Definitions
- This invention relates to a transferring apparatus, particularly to a transferring apparatus used for supplying and retrieving a semi-processed work to and from a pressing machine or stamping machine, and to a large transferring apparatus using two transferring apparatuses which transfer a large work by holding with more than two places spaced widely.
- JP '262 the arm operating apparatus of the robot of joint type is disclosed.
- the first arm is rotatably attached to a pedestal, and the second arm whose length is same as the first arm is rotatably coupled to the front end of the first arm.
- the belt is wrapped between the first pulley fixed to the pedestal and the second pulley fixed to the base end of the second arm.
- the diameter of the second pulley is made to be 1 ⁇ 2 of the diameter of the first pulley.
- the first arm swings reciprocatingly by a motor.
- the first arm swings and the second arm also swings as the same angle as the first arm synchronized with the first arm through the pulley and the belt. Resultantly, the grip portion attached to the front end of the second arm operates reciprocatingly in liner motion.
- JP '262 the apparatus to parallely move the grip portion is disclosed.
- the belt is wrapped between a fixed pulley fixed to the pedestal, and the intermediate pulley which is concentric with the second pulley and which has the same diameter as the first pulley.
- the driven pulley of the same diameter as the intermediate pulley is fixed to the grip portion.
- the belt is wrapped between the intermediate pulley and the driven pulley.
- JP '183 the handling robot having the first arm and the second arm which are about same as those of JP '262 is disclosed.
- the pedestal is rotated horizontally, and the grip portion is rotated by a motor attached to the joint portion of the second arm and the first arm through the pulley and the belt.
- JP '393 the work retrieving apparatus having the first arm and the second arm which are about same as JP '262 is disclosed.
- the first arm is rotated or driven by the first motor attached to a pedestal, and the second arm is rotated by a second motor through the pulley and the belt.
- the chuck portion (grip portion) attached to the front end of the second arm can be moved to the arbitrary position in a vertical plane and with arbitrary trajectory by two axis control.
- the two axis control can independently rotate the first arm and the second arm. For example, it can be moved up and down to retrieve the molded object from the extrusion molding machine, and it can move the object horizontally to a predetermined position.
- the length of the first arm and the second arm may be not identical.
- JP '976 the vacuum robot for transferring substrates which is about same as JP '393 in the point that the first arm and the second arm are made to operate independently.
- JP '381 the transferring apparatus of horizontal revolution type which is about same as JP '183 is disclosed.
- the apparatus has a tilt mechanism to be capable of controlling the angle of a hand independently to a second arm.
- JP '406 the work transferring apparatus in the tandem press line is disclosed.
- This apparatus has a pair of beam installed between adjacent press machines; the carrier running along the beam; the swinging table swingably hanged to the carrier and being swingingly driven; the feed lever provided by the swinging table through the linear moving mechanism (extend/retract mechanism).
- the extension and retraction of the feed lever are independently operated. And these operations are combined to carry out the work transfer between the pressing machines of the tandem press line.
- the arm equipped with the vacuum cup is further provided swingably at the front end of the feed lever extending and retarecting from the swinging table.
- the transferring apparatus for large machines is disclosed, in which the work transferring apparatuses provided as the pair in left and right, support the cross bar extending left and right, and the vacuum cup provided in the cross bar holds the work.
- the apparatus of JP '262 has a merit that while having a joint type structure suitable for transferring a comparatively heavy work, it can transfer the work linearly.
- the length of the first arm and the length of the second arm are identical, it is necessary to adapt the height of the pedestal to the transfer level.
- it is necessary to adapt the height of the pedestal of the robot to the transfer level such as in the case that the installed position of the pedestal and the mounted position of the work, for example, the pressing die is different. This is same for the handling robot of JP '183, even if the first arm and the second arm are changed so as to turn around a horizontal axis to make it suitable for the transfer of a heavy load.
- the product retrieving apparatus of JP '393 is that which independently controls a first arm and a second arm. In this, even if the point that the length of the arms is not identical can be applied to the apparatus of JP '262 in which the arms are synchronously swung. It cannot perform linear transfer if nothing is done. This is also same for the JP '976. Moreover, in the transferring apparatus of JP '381, the length of the first arm and the second arm is equal (see paragraph [0014]).
- the work transferring apparatus of JP '406 performs up and down movement and forward and backward movement by combining the swinging of a swinging table. Therefore, the linear movement (extend/retract) of a feed arm is achieved, but it needs a large stroke in the linear movement mechanism, making it unsuitable for high speed transfer.
- This invention is directed to provide a transferring apparatus which can transfer a work at high speed about linearly by synchronizing mechanically a first arm and a second arm which are rotatably coupled. Further, this invention is directed secondly to provide a large transferring apparatus suitable for a heavy load using this transferring apparatus.
- a transferring apparatus of this invention is composed of a pedestal having a first axis, a first arm having a base end and a front end, a second arm having a length different to the first arm and having a base end and a front end, a hand attached to the front end of the second arm, and a drive means to swing the first arm reciprocatingly.
- the first arm is swingably provided around the first axis, and the front end is equipped with a second axis parallel with the first axis.
- the second arm is swingably provided around the second axis.
- the transferring apparatus further has a first circular plate having a center and a periphery, a second circular plate having a center and a periphery, and a torque transmission means interposed between the periphery of the first circular plate and the periphery of the second circular plate.
- the first circular plate is attached to the pedestal, and the center is within the first axis.
- the second circular plate attached to the base end of the second arm, and the center is within the second axis.
- the torque transmission swings the second arm synchronously with the first arm.
- a ratio of a diameter of the first circular plate and a diameter of the second circular plate is set so that the front end of the second arm moves about linearly when the second arm swings synchronously with the first arm.
- an angle adjusting mechanism of the second arm can adjust the angle of the first circular plate.
- a parallel movement mechanism can be included, which maintains the hand at a predetermined angle always with respect to a rest frame regardless of the turn of the first arm.
- Another aspect of this invention comprises a pedestal having a first axis, a first arm having a base end and a front end, a second arm having a base end and a front end, a third arm having a front end, a hand attached to the front end of the third arm, and a drive means to swing the first arm reciprocatingly.
- the first arm is swingably provided around the first axis, and the front end is equipped a second axis parallel with the first axis.
- the second arm is swingably provided around the second axis.
- the third arm protrudes from the front end of the second arm and the third arm performs liner motion against the second arm.
- the second aspect of the transferring apparatus further comprises a first circular plate having a center and a periphery, a second circular plate having a center and a periphery, a torque transmission means interposed between the periphery of the first circular plate and the periphery of the second circular plate, an extend/retract drive means to extend and retract the third arm, and a control means to control so that the front end of the third arm moves about linearly accompanying with a swing of the first arm.
- the first circular plate is attached to the pedestal and the center is within the first axis.
- the second circular plate is attached to the base end of the second arm and the center is within the second axis.
- the torque transmission swings the second arm synchronously with the first arm.
- a tilt mechanism to swing the hand around the front end of the second arm or the front end of the third arm can be included.
- first circular plate and the second circular plate are pinions
- the torque transmission means is equipped with a rack meshing with these pinions.
- the pair of racks are arranged at both sides in left and right line connecting the first axis and the second axis, and at least one pinion is provided so as to tolerate the variation of the distance to the other pinion. Further, at the same time, the one pinion is energized or forced in a departing direction or an approaching direction to the other pinion.
- a large transferring apparatus of this invention includes the transferring apparatus of the above invention arranged as one pair in left and right of processing machine, a beam to interconnect the hands of these transferring apparatuses, and a work holding means provided in the beam.
- the first axis and the second axis of the left and the right transferring apparatus are arranged concentrically to each other. Further, the first axis and the second axis extend perpendicular to the transfer direction of the work and horizontally, and the each left and the right drive means operates synchronously mutually.
- the transferring apparatus of this invention since the length of the first arm and the second arm is different, it is not necessary to adapt the pedestal to the transfer line, allowing the installation at a suitable position. Further, because the ratio of the first circular plate and the second circular plate is set to move the front end of the second arm about linearly when the second arm swings synchronously with the first arm, even though the length of the first arm and the second arm is different. Therefore, it is possible to perform the transfer similar to the conventional transferring apparatuses.
- the transferring apparatus equipped with an angle adjusting mechanism of the second arm to adjust the fixed angle of the first circular plate can tilt the moving trajectory of the hand to a reference position by shifting the phase of the second arm by adjusting the fixed angle.
- the transferring apparatus can be equipped with a parallel movement mechanism to maintain the hand at a predetermined angle with respect to a rest frame regardless of the swing of the first arm. Since the posture of a work does not change when the hand moves, the design or the planning of the hand and the positioning jig etc. are easy.
- the transferring apparatus of this invention since fundamental movements can be achieved by the joint type first arm and the joint type second arm, rapid linear movement is possible. Moreover, appearing and disappearing of the third arm from the front end of the second arm allow fine movements such as avoiding a pressing die. Further, the transferring apparatus which is equipped with a tilt mechanism swinging the hand to the second arm, can change the angle of a work when in transferring a work and in mounting it on a jig etc. Hence, it is possible to transfer at an angle suitable for transferring, and to mount at an angle suitable for mounting.
- the first circular plate and the second circular plate may be pinions, and the torque transmission means may equipped with racks meshing with these pinions. It can make the torque transmissibility large compared with that using a belt. It may be that the rack are arranged at both side as one pair in left and right of a line connecting the first axis and the second axis, and at least one pinion is provided so as to tolerate the variation of the distance to the other pinion, and one pinion is energized in a direction to depart from or to become close to the other pinion.
- the transferring apparatuses arranged as one pair in the left and right of a processing machine transfer one sheet or one each of work in a coordinated manner, thereby the weight imposed on one apparatus becomes small. Further, the edge portion of a work can be stably held and the load are reduced, therefore the load torque applied to the hand becomes small.

- FIG. 16 is a side view showing the working status of the transferring apparatus.
- the transferring apparatus 10 shown in FIG. 1 includes a pedestal 11 , a first arm 12 of which the base end is swingably provided to the pedestal and is extended upward in a reference position, a second arm 13 which is provided swingably in the upper end of the first arm and is extended downward in the reference position, a hand 14 attached to the front end of the second arm, and a first motor M 1 to reciprocatingly swings the first arm 12 to the pedestal 11 .
- the center J 1 (a first axis) of rotation or swing of the first arm 12 and the center J 2 (a second axis) of rotation or swing of the second arm 13 are horizontal respectively and in parallel mutually.
- this transferring apparatus 10 further has a synchronous swinging mechanism 15 to swing the second arm 13 synchronously with the swing of the first arm 12 , as shown in FIG. 2 a.
- This mechanism 15 is equipped with a first pinion 16 installed so as not to move to the pedestal 11 , a second pinion 17 rotatably provided around the second axis J 2 and fixed to the second arm 13 , and one pair of left and right racks 18 , 19 which mesh with those pinions 16 , 17 and move up and down along the first arm 12 .
- the racks 18 , 19 may be the one of either the left or the right.
- the first pinion 16 is attached to the pedestal 11 through a second motor M 2 which is a component of a later described second arm angle adjusting mechanism 20 . It does not rotate as far as the second motor M 2 does not rotate.
- teeth 18 a, 19 a are formed in the portion only where meshing with the pinions 16 , 17 , and the racks 18 , 19 are supported slidably by the first arm 12 .
- the length L 2 of the second arm 13 (the distance between the center J 2 of rotation of the second arm and the hand 14 ) is shorter than the length L 1 of the first arm (the distance between the first axis J 1 and the second axis J 2 ). It is about 1 ⁇ 2 of the length L 1 of the first arm 12 .
- the diameter D 2 of the second pinion (the diameter of the pitch circle) is about 9/23 of the diameter D 1 of the first pinion 16 , which is made to be smaller than 1 ⁇ 2.
- the first arm 12 coupled to the output shaft of the motor M 1 swings as much as angle ⁇ 1 clockwise, for example, as shown in FIG. 2 b, around the first axis J 1 .
- the reference numeral K is a reference line of vertical direction.
- the first pinion 16 does not rotate, the one rack 18 supported by the first arm 12 descends toward the base end side of the first arm 12 .
- the other rack 19 performs linear movement so as to ascend toward the front end side.
- the second pinion 17 swings anti-clockwise until angle ⁇ 2 to the vertical line.
- the reference numeral 22 is a floor face.
- FIG. 2 b and FIG. 3 The graph of the relation between the height H and the angle ⁇ 1 of the first arm is shown in FIG. 2 b and FIG. 3 . As seen in the figures, the front end of the second arm 13 moves closer to a horizontal line shown by the chain line P.
- the front end of the second arm 13 moves horizontally strictly, as the apparatus of JP '262. But since in this transferring apparatus 10 , the length of the first arm 12 is about twice of the length L 2 of the second arm, and the ratio of the diameter D 1 of the first pinion 16 and the diameter D 2 of the second pinion 17 is about 23/9, the movement of the front end of the second arm does not becomes strictly horizontal. It deviates from the horizontal line along the way, but it is not much a problem in practice.
- the length L 2 of the second arm 13 is shorted than the length L 1 of the first arm.
- the ratio of the diameter D 1 of the first pinion 16 and the diameter D 2 of the second pinion 17 are suitably selected, as shown in FIG. 2 b and FIG. 3 . Therefore, the hand 14 of the front end of the second arm 13 can be moved about horizontally. Further, as found from FIG. 2 b, in the status that the first arm 12 is swung large to the reference line K, the second arm 13 swings further large to the vertical straight line K 2 .
- the first arm 12 is swung as much as the identical angle from the reference line to the front side and the back side. By swinging back and forth as thus, a work which is press-worked in the foregoing process of the left edge can be moved to the next pressing die. But, the swinging angle of first arm 12 is not necessary to be made identical in the fore and back. Moreover, it can be selected suitably according to the shape of the work to be transferred, the jig or the pressing die to retrieve the work, and the jig or the pressing die of the next process to which the work is supplied.
- the length of the second arm 13 is shortened as described above, even when the pedestal 11 is installed on the floor face 22 , the work can be transferred with the transfer level higher than the floor face.
- the work supplying height the height of the upper face of a pressing die
- the second arm 13 which is provided at the tip side of the apparatus and which moves largely, can be made light, thereby the whole inertia becomes small and the power of the first motor M 1 can be made small.
- This angle adjusting mechanism 20 of the second arm is that in which the second motor M 2 is connected to the first pinion 16 and the second arm 13 only is made to be advanced or delayed as much as the predetermined angle ⁇ 3 , while the first arm 12 remains stationary.
- the phase of the second arm 13 is made to be advanced as much as ⁇ 3 and the first arm 12 is swung by driving the first motor M 1
- the hand 14 of the front end of the second arm 13 moves along the inclined transfer line as shown by the chain line P 2 in FIG. 5 . Accordingly, in the case that there are obstacles in its way, transfer can be carried out via a path which avoids the interference with the obstacles. Inversely, in the case that the transfer is carried out with its movement being delayed, it becomes a transfer line inversely inclined, as shown in the imaginary line P 3 .
- a first gear 26 is provided concentrically to the first axis J 1 .
- This first gear 26 is coupled to the second gear 28 which is provided rotatably concentrically to the second axis J 2 through a torque transmission mechanism 27 .
- the torque transmission mechanism 27 comprises semi-circular sector gears 31 , 32 provided rotatably around shafts 29 , 30 supported respectively by the first arm 12 , a link 33 coupling those sector gears 31 , 32 .
- the link 33 is composed of two units which is one pair of the left and the right, but it may be one unit.
- the other torque transmission mechanism such as a chain, a pulley, a timing pulley can be adopted.
- the hand 14 of the front end of the second arm 13 is supported rotatably in the second arm 13 by a shaft 34 .
- a first timing pulley 35 is coupled to the second gear 28 so as to co-rotate, and a second timing pulley 36 is fixed to the shaft 34 so as to co-rotate.
- the timing pulleys (geared pulley) 35 , 36 are mutually coupled by a timing belt 37 (geared belt) which is a wrapping connector.
- the gear ratio of the first gear 26 and the second gear 28 is 1, and the gear ratio of the first timing pulley 35 and the second timing pulley 36 is also 1.
- the first gear 26 , the torque transmission mechanism 27 , the second gear 28 , the first timing pulley 37 , and the second timing pulley 36 composes a parallel movement mechanism 24 of the hand.
- a third motor M 3 is provided in the pedestal 11 .
- a drive gear 38 coupled to the output shaft of the third motor M 3 is meshed with the first gear 26 to constitute a tilt mechanism of the hand.
- This shaft 34 also does not rotate with respect to the rest frame similar to those described above. Accordingly, even when the second arm 13 swings accompanying the swing of the first arm 12 , the hand 14 moves about horizontally maintaining the original angle (see FIG. 6 b ). Thereby, the work held by the hand is transferred with its posture not changing, achieving parallel movement function.
- the tilt mechanism When the angle of the work is desired to be changed while retrieving or supplying a work, the tilt mechanism is used. In other words, when the position of the first arm is placed in any of the position, the third motor M 3 is rotated to rotate the drive gear 38 . This rotation is transmitted to the first gear 26 , and transmitted to the shaft 34 of the hand 14 through the torque transmission mechanism 27 , the second gear 28 , the first timing pulley 35 , the timing belt 37 , and the second timing pulley 36 . And the hand 14 rotates as much as the same predetermined angle as the first gear 26 (see FIG. 6 c ). Thereby, the posture of the work can be changed according to need.
- the torque transmission mechanism 27 equipped with two semi-circular sector gears 31 , 32 , is interposed between the first gear 26 and the second gear 28 .
- the semi-circular sector gear 26 a in place of the first gear and a rotating link 28 a in place of the second gear are directly coupled by a link 33 .
- the parallel movement mechanism of FIG. 6 a or FIG. 7 a is usually made to be a standard equipment. But there is a case that the adjustment mechanism and the tilt mechanism of the second arm are not necessary, this is usually made to be an option, because the second motor M 2 and the third motor M 3 should be added.
- the transferring apparatus 10 of FIG. 1 is arranged to be one pair in left and right spaced at an interval, and at the same time, a common transfer beam 41 is used as a hand.
- a vacuum cup or gripper which actually holds a work is attached to the beam 41 detachably.
- the left and the right transferring apparatus 10 is made to be plane symmetry, and as the pedestal 11 , that which is common large one is used.
- the second arm adjusting mechanism and the tilt mechanism are not equipped.
- the output shaft 42 of the first motor M 1 and the base end of the first arm 12 are coupled by a drive gear 43 fixed to an output shaft 42 and a driven gear 44 fixed to the first arm 12 , as shown in FIG. 9 .
- the motion of the large transferring apparatus 40 is substantially same as the transferring apparatus 10 of FIG. 1 as shown in FIG. 10 . And it can transfer one relatively large work in cooperation of the left and the right transferring apparatus 10 .
- the transfer distance can be lengthened by swinging left and right the first arm 12 , same as the case of FIG. 3 . Therefore, the tilt angle of the second arm 13 becomes small in the position of retrieving and supplying the work, and it makes the retrieving and supplying of the work easy.
- the transmission of power from the first pinion to the second pinion is done by the racks, but, the power transmission can be done by a gear train, as shown in FIG. 11 a. Moreover, as shown in FIG. 11 b, it can be done by pulleys 46 , 47 and a belt 48 , or a timing pulley and a timing belt, further, it can be done by a sprocket and a chain.
- the second pinion 17 is provided in some measure movable in the direction of the axis line of the arms to the first arm 50 , and is energized to the first pinion 16 side by a spring 51 .
- this first arm 50 there is no clearance between the upper side of the teeth of the left and the right racks 18 , 19 and the lower side of the teeth of the second pinion 17 , and the clearance is brought together between the lower side of the left and the right racks 18 , 19 and the upper side of the teeth of the second pinion 17 .
- the right side of the first pinion 16 , the right rack 19 , and the right side of the second pinion 17 transmit the power without clearance opposing the given energy, and do not transmit the power through the left rack 18 .
- any of the rack and pinion transmits the power without clearance. Accordingly, when the direction of rotation of the first pinion 16 changes, in other words, the swinging direction of the first arm 50 changes, no backlash is generated. Thereby, the vibration of the second arm is suppressed. This effect is same as the case that the second pinion 17 is energized in the direction of the front end side of the first arm 50 , in other words, the opposite side to the first pinion. Moreover, the first pinion 16 may be energized in the direction of the second pinion 17 side, or in the reverse direction. As the energizing means, other than a spring 51 , such as a gas spring utilizing an air cylinder can be used.
- FIG. 12 a and FIG. 12 b show respectively the mechanism of the other embodiments which drive without backlash.
- the racks 18 , 19 are meshing with the both sides of the first pinion 16 and an intermediate pinion 52 .
- the first pinion 16 is energized to the intermediate pinion 52 side by energizing means such as a spring 56 a, same as the above described embodiment.
- energizing means such as a spring 56 a, same as the above described embodiment.
- the second pinion 17 meshes with those idle gears 54 , 55 .
- the left and right idle gears 54 , 55 are energized in the direction of drawing apart mutually by an energizing means such as a spring 56 b.
- an energizing means such as a spring 56 b.
- the first pinion 16 rotates clockwise, the power is transmitted to the second pinion 17 without clearance through the left rack 18 and the left idle gear 54 .
- the power is transmitted without clearance through the right rack 19 and the right idle gear 55 . Accordingly, same as described above, when the swinging direction of the first arm changes, no backlash is generated.
- a driven gear 58 is fixed to the first arm 12 so as not to rotate. And, the rotation of the drive gear 59 , driven by the first motor, transmits the power to the driven gear 58 respectively through the left and the right intermediate pinions 60 , 61 provided rotatably in the first arm 12 .
- the each intermediate pinion 60 , 61 is fixed so that the large diameter gears 60 a, 61 a meshing with the drive gear 59 and the small diameter gears 60 b, 61 b meshing with the driven gear 58 are made to corotate.
- the direction of the backlash of the drive gear 59 and the large diameter gear 60 a, and direction of the backlash of the small diameter gear 60 b and the driven gear 58 are determined, so that the rotation is transmitted to the driven gear 58 without backlash through the left intermediate pinion 60 when the drive gear 59 rotates in one direction.
- the direction of the backlash of the drive gear 59 and the large diameter gear 61 a, and the direction of the back lash of the small diameter gear 61 b and the driven gear 58 are adjusted so that the rotation is transmitted to the driven gear 58 without backlash through the right intermediate pinion 61 when the drive gear 59 rotates in the reverse direction. Therefore, the rotation of the first motor can be transmitted without backlash in any direction of the rotation, and it suppresses the vibration even when the swinging direction of the first arm changes same as the case of FIG. 12 a.
- the extend/retract arm 62 shown in FIG. 13 a, FIG. 13 b is equivalent to the second arm 13 of the transferring apparatus 10 of FIG. 1 , FIG. 2 , and is provided with an extend/retract mechanism.
- the extend/retract arm 62 is equipped with a rectangular pipe like arm holder 63 attached rotatably to the first arm 12 , and a sliding arm 64 housed slidably to the arm holder.
- the arm holder 63 is the second arm
- the sliding arm 64 becomes a third arm provided slidably to the second arm.
- the shaft 17 a of the second pinion 17 of the first arm 12 is fixed to the rear surface side of the upper end of the arm holder 63 .
- an opening 65 is formed in the side of the arm holder 63 , and a nut holder 66 fixed to the side of the sliding arm 64 protrudingly from the opening 65 .
- the nut 66 is omitted for easy understanding.
- upper and lower brackets 67 , 68 are attached, and these brackets 67 , 68 support a screw shaft 69 rotatably.
- the upper end of the screw shaft 69 is coupled with the output shaft of a fourth motor M 4 .
- a nut 70 screwing together with the screw shaft 69 is fixed to the nut holder 66 .
- the screw shaft 69 and the fourth motor M 4 etc. are also omitted.
- the extend/retract arm 62 composed as thus, when the fourth motor M 4 rotates in one direction, the screw shaft 69 rotates, the sliding arm 64 to which the nut 70 screwing together with the screw shaft descends, and its front end further protrudes from the lower end of the arm holder 63 . Thereby, the extend/retract arm 62 extends.
- the upper portion of the sliding arm 64 always protrudes from the upper end of the arm holder 63 , therefore the term “extends” here means the distance between the turning center of (the second axis J 2 ) of the arm holder 63 and the front end of the sliding arm 64 and the substantial whole length of the extend/retract arm 62 (the length of the sliding arm 64 ) does not change.
- the fourth motor M 4 rotates in the inverse direction, the sliding arm 64 ascends and its front end moves toward the direction of withdrawing. Thereby, the extend/retract arm 62 retracts.
- the reference numeral 71 of FIG. 13 a is a balance cylinder which energizes the sliding arm 64 upward in order to cancel the weight of the sliding arm 64 .
- a spring can be also adopted.
- As the screw shaft 69 and the nut 70 in order to reduce the friction torque, it is preferable to adopt a ball screw and a ball nut.
- the structure of the slide portion of the arm holder 63 and the sliding arm 64 is preferable to be composed by a linear motion bearing (linear ball bearing) 72 and a linear motion rail (LM rail) 73 fixed to the sliding arm 64 , as shown in FIG. 14 a. In this case, to receive the torque of rotational direction, two linear motion rails 73 are adopted.
- an independent tilt mechanism 74 is provided in the sliding arm 64 as shown in FIG. 14 b.
- This tilt mechanism 74 is composed of a first gear 75 and a second gear 76 rotatably provided in the upper end and the lower end of the sliding arm 64 respectively, a torque transmission mechanism 77 which transmits torque between the first gear 74 and the second gear 76 , a fifth motor (reference numeral M 5 of FIG. 13 b ) which rotatively drives the first gear 75 , and a hand holder 78 coupled with the second gear 76 .
- the torque transmission mechanism 77 comprises a semicircular sector gear 79 meshing with the first gear 75 , a sector gear 80 meshing with the second gear 76 , and a link 81 to couple these sector gears 79 , 80 mutually.
- other torque transmission mechanisms such as a pulley and a belt, particularly, a timing pulley and a timing belt, or a sprocket and a chain can also be adopted.
- fluid motors such as air motor or an oil hydraulic motor can be also adopted for saving the weight.
- the tilt mechanism 74 composed as above, when the fifth motor M 5 rotates in one direction, the hand holder 78 rotates through the first gear 75 , the torque transmission mechanism 77 , and the second gear 76 , and it control the tilt of the hand 14 holding a vacuum cup.
- the control of the fifth motor M 5 can be used to hold the tilt of the hand 14 horizantly in response to the angle of the extendable arm 62 , namely the tilt of the arm holder 63 . Further, the control of the fifth motor M 5 can also be used to tilt the hand 14 avoiding the interference with the pressing die or a pressing machine.
- the transferring apparatus 82 shown in FIG. 15 and FIG. 16 is equipped with the first arm 12 rotatably provided around the first axis J 1 to the pedestal and the extend/retract arm 62 provided rotatably around the second axis J 2 in the front end of the first arm 12 , which are about similar to FIG. 1 . Since the length of the extend/retract arm 62 extends and retracts freely, as the case of the transferring apparatus 10 of FIG. 1 , the ratio of the length of the first arm 12 and the extend/retract arm 62 , and the ratio of the diameter of the first pinion 16 and the second pinion 17 are not so important.
- the length L 3 (the distance between the second axis J 2 and the turning axis J 3 of the hand holder) in the state that the extendable arm 62 is retracted is made to be same as the length L 1 of the first arm, the ratio of the diameter of the first pinion (first sector gear) 16 and the diameter of the second pinion 17 can be made to be 2:1.
- the length L 3 of the extend/retract arm 62 may be made always longer than the length L 1 of the first arm 12 , as shown in FIG. 16 . Further, it may be made shorter in the normal state and may be extended when needed. In this case, the length of the extending arm 62 and the first arm 12 may instantly become congruent, but fundamentally, it is the different length.
- the torque transmission can be made by one pair of the left and the right racks between the first pinion 16 and the second pinion 17 , same as the case of FIG. 1 and FIG. 2 .
- the same diameter intermediate pinion 52 provided in the upper portion of the first arm 16 and the second arm 17 are coupled by one pair of the left and the right racks not shown in the figure.
- the intermediate pinion 52 and the second pinion 17 fixed to the arm holder 63 , are coupled through one pair of idle gears 54 , 55 .
- the reason that the racks and the idle gears 54 , 55 are provided as one pair left and right, is to eliminate the backlash.
- the extend/retract arm 62 when the first arm 12 is in the central reference position, the extend/retract arm 62 is retracted, and when the apparatus 82 is in the sate of retrieving a work in a pressing machine of upstream side (left side of FIG. 16 ), the extend/retract arm 62 is extended, as shown in FIG. 16 . And, after taking out the work, when it passes the reference position, the extend/retract arm 62 is retracted, and when the apparatus 82 is in the state of placing a work in a pressing machine of downstream side (right side of FIG. 16 ), the extend/retract arm 62 is extended again. And, when returning to the reference position, the extend/retract arm 62 is retracted.
- the pressing die of the pressing machine of upstream side and down stream side shown by the imaginary line it can approach from the upper side and can withdraw to the upper direction.
- the retrieving of a work from the pressing die and the supply of a work to the pressing die becomes smooth.
- the reference numeral 83 of FIG. 16 it is possible to overgo the obstacle by partially raising the trajectory of movement of the hand 14 .
- the moving trajectory of the hand 14 is selected so that the work does not interfere with the pressing die etc.
- the first motor M 1 to turn the first arm 12 and the fourth motor M 4 to move the sliding arm 64 are computer-controlled so as to realize the above described two dimensional trajectory. Moreover, the rotation of the fifth motor M 5 of the tilt mechanism 74 of FIG. 14 b is controlled so as to be electrically synchronized with the swing of the first arm 12 .
- the fundamental motion of the transfer is based on the swing of the first arm 12 around the first axis J 1 and the turn of the arm holder 63 mechanically coupled to the first arm 12 around the second axis J 2 . Thereby, the small amount of movement of the sliding arm is sufficient. Hence, a work can be transferred rapidly and safely, compared with the transferring apparatus of JP '406.
