Abstract

The invention relates to a winding machine to wind a continuously fed thread on a spool; wherein the thread is guided into a cross-winding device consisting of a pre-cross-winding unit and a grooved roller located downstream from the path of the thread. The winding machine has a thread deflection device in order to change the thread from a full spool clamped on a spool spindle to an empty spool clamped on another spool spindle by rotating a winding turret. The thread deflection device consists of a guide plate which is guided parallel to the periphery of the grooved roller and a thread guide which can be positioned parallel to the axis of the spool spindle. By pivoting the guide plate, the thread can be thus guided from the cross-winding device without substantially changing the winding.

Description

Winding machine

The invention relates to a dishwashing machine for winding a thread running continuously into a bobbin according to the preamble of claim 1.

Such a winding machine is known from DE 23 64 284 (= US Pat. No. 3,999,715). Here, a continuously running thread is wound into a bobbin. After the bobbin is completely wound, there is an automatic change from the full bobbin to an empty tube, the thread being guided by means of a thread folding device in such a way that it is taken over by the empty tube. For this purpose, the full bobbin and the empty tube are each clamped on a winding spindle, which are cantilevered and rotatably mounted on a winding turret. To transfer the thread, the full bobbin is pivoted from the winding area into a changing area and the empty tube from the changing area into the winding area by rotating the winding turret. To transfer the thread, the thread must be lifted out of the traversing device by means of the thread folding device. The traversing device consists of a pre-traversing unit and a grooved roller. The grooved roller is arranged directly in front of the bobbin to be wound and is partially wrapped around by the thread, the thread being guided in a thread guide groove for placement on the bobbin.

The known thread transfer device therefore guides the thread by means of a thread guide in a spacious loop outside the traversing device. Such large deflections generate correspondingly high thread tensions in the thread. These thread tensions can lead to the thread tearing before the thread has been caught on the empty tube. Accordingly, it is an object of the invention to further develop a winding machine of the type mentioned at the outset in such a way that the thread transfer from the full bobbin to the empty tube is as gentle as possible, so that the thread tension fluctuates as little as possible during the transfer.

This object is achieved according to the invention by a winding machine with the features of the characterizing part of claim 1 and by a method with the features of claim 11.

The winding machine according to the invention is characterized in that the degree of wrap of the thread that the thread assumes during the traversing on the grooved roller is approximately maintained when the thread is turned over. The thread pulling forces generated in the thread by friction when the thread is turned from the full bobbin to the empty tube are thus insignificantly changed compared to the thread pulling forces during the winding travel. For this purpose, the thread deflection device of the winding machine has a guide plate guided parallel to the circumference of the grooved roll and a thread guide that can be positioned parallel to the axis of the winding spindles. By moving the guide plate from a rest position into an operating position, the leading edge of the guide plate facing the thread will take over the thread and lift it out of the engagement of the pre-curtain and the grooved roller. By means of the thread guide, the thread can now be guided into a catch position in which the thread is caught in a catch slot of the empty tube.

The thread transfer device of the winding machine according to the invention can advantageously be used when the thread is first placed on an empty tube and when the thread is turned from a full bobbin to an empty tube.

The development of the winding machine according to claim 2 has the advantage that the wrapping of the thread on the grooved roller and the wrapping of the thread on the guide plate are essentially the same. At the same time, the guide plate serves to cover the grooved roller. Here, the guide plate can be designed such that the area of the grooved roller that is not contacted by the thread is completely covered in the rest position of the guide plate. This reduces the air turbulence generated by the grooved roll, so that the thread can be safely guided in the thread guide groove of the grooved roll during traversing.

Due to the design of the winding machine according to claim 3, a particularly gentle transfer of the thread from the traversing device is achieved. The direction of movement of the guide plate is identical to the direction of the thread. In this arrangement, the thread is first guided out of the pre-traversing unit during the movement of the guide plate, which is particularly advantageous in the case of a grooved roller which has a thread guide groove only in the end regions of the traversing stroke.

In the case of a grooved roller which contains thread guide grooves over the entire traversing stroke on the circumference, the configuration of the winding machine according to claim 4 can preferably be used. With this arrangement, the thread is first removed from the engagement of the grooved roller, the thread being able to follow the traversing movement of the pre-traversing unit by sliding along the leading edge of the guide plate without impairment.

The particularly advantageous development of the winding machine according to claim 5 is particularly suitable when the thread is turned from a full bobbin to an empty tube. Here, the full bobbin is moved into an outer position on the winding turret by means of the winding spindle, so that the empty tube and the full bobbin are positioned offset to one another in the direction of thread travel. This avoids that while the thread is being guided in the catch position, it does not run off the full spool. Until the thread is caught in a catch slot of the empty tube, the thread is wound on the full spool. In addition, this version of the winding machine has a very high contact security. The thread can be guided in a parallel thread run to the catch slot in the empty tube. The entire length of the catch slot is thus available for catching the thread.

Here, the configuration of the winding machine according to claim 6 is preferably to be used in order to be able to deposit the thread already guided from the traversing on the full bobbin without forming a binding bead. Only when the full spool is moved to its outer position is a binding bead wound on the full spool. Another advantage of this embodiment is that no additional drive means are required to displace the winding spindle.

In order to prevent the thread from falling off the full bobbin, it is also possible, however, that in the region between the empty tube and the full bobbin, a lay-on plate with a guide groove swivels in during the folding, so that the thread is guided in a fixed position in the guide groove the full spool runs up and thus forms a binding bead. After the thread between the empty tube and the full bobbin is gripped by the guide groove, the positionable thread guide moves into the catching position, so that the thread runs through in the area of the catching slot on the empty tube and can be taken over by the empty tube.

Another particularly preferred embodiment of the winding machine provides that the winding turret can be driven with the opposite direction of rotation to the direction of rotation of the winding spindle. This ensures that the empty tube moves in the opposite direction to the thread running during catching. The relative movement between the empty tube and the thread leads to the fact that the empty tube very quickly leads the required clamping forces to build up a thread tension, which causes the tearing of the thread in the section between the empty tube and the full spool. On the other hand, this arrangement allows the wrap around the empty tube required for catching the thread to be kept very low, so that no sudden changes in tension in the thread occur when the empty tube is pivoted into the thread path.

Due to the advantageous development of the winding machine according to claim 8, the looping of the thread on the empty tube in the winding area can be minimized. Only after the thread has been brought into the catching position is the feed plate pivoted into the thread path between the empty tube and the full spool, so that the leading edge deflects the thread. This sets the looping of the thread on the empty tube required for catching.

The design of the winding machine according to claim 10 is particularly advantageous in order to avoid the loose thread end of the full bobbin coming into the area of the bobbin to be newly formed. Here, the swivel direction of the contact plate and the rotational movement of the full spool are aligned in the alternating area. This prevents the loose thread end from hitting the leading edge of the feed plate.

Further advantages of the winding machine according to the invention are explained on the basis of the exemplary embodiments shown in the attached figures.

They represent:

Thread over; Fig. 4 shows schematically the side view of another embodiment of the dishwasher.

In all exemplary embodiments of the winding machine shown, the thread 1 is supplied to the winding machine without interruption at a constant speed. The thread 1 is first passed through the head thread guide 2, which forms the tip of the traversing triangle. The thread then arrives at the traversing device 3. The traversing device 3 consists of a pre-traversing unit 4 and a grooved roller 8 connected in the thread run. Such a traversing device is described, for example, in US Pat. No. 3,797,767. The pre-traversing unit 4 is preferably formed from a reversing thread shaft 5 and a traversing thread guide 7 guided in a straight guide 6. Here, the traversing thread guide 7 is guided in a groove of the reversing thread shaft 5 and driven by the driven reversing thread shaft 5 to a reciprocating movement. The grooved roller 8 has thread guide grooves 9 on the circumference. Since the reverse thread shaft 5 and the grooved roller 8 are driven at a synchronous circumferential speed, the traversing thread guide 6 serves to guide the thread in the thread guide groove 9. The reversing thread shaft 5 is matched to the grooved roller 8 in such a way that the traversing thread guide 7 securely guides the thread with sufficient advance the thread guide groove 9 conducts. The thread guide groove 9 takes over the actual laying of the thread 1 on a spool 15. The thread 1 is deflected at the circumference of the grooved roller 8 by approximately 90 ° and then runs onto the spool 15. To fix the deposited thread, a pressure roller 10 is arranged axially parallel to the grooved roller 8 and lies on the spool surface of the spool 15 with a predetermined contact force on.

The traversing device 3 and the pressure roller 10 are arranged on a height-adjustable slide 12. The carriage 12 is moved back and forth in a guide 13 in a vertical direction by a pneumatic relief device (not shown). Compressed air is applied to the pneumatic relief device in such a way that it fully or partially compensates for the slide weight and, if necessary, generates an additional contact force between the pressure roller 10 and the adjacent coil. Such a relief device can also be controlled via a programmable control device in such a way that a course of the contact force, which is predetermined for the winding travel, acts between the pressure roller 10 and the coil 15.

The coil 15 is formed on the sleeve 16. The sleeve 16 is clamped on the rotatably mounted winding spindle 17. The spool 15 is driven by the spool 17 connected to a spindle drive 36 (FIG. 3). However, the coil 15 can also be driven on its circumference by the pressure roller 10.

In Fig. 1, the winding spindle 17 with the sleeve 16 clamped thereon and the coil 15 formed thereon is in the winding area. At this time there is a second winding spindle 18 with an empty tube 19 stretched thereon in an alternating area. Both winding spindles 17 and 18 are cantilevered in a rotatable turret 20 freely rotatable. The winding turret 20 is rotatably mounted in the machine base 21 of the winding machine and can be pivoted by the turret drive 40 (FIG. 3), so that the winding spindles 17 and 18 can alternately be pivoted into the winding area or changing area when the bobbin 15 on the one of the spindles is fully wound. The turret 20 is for this purpose connected to the turret drive 40 (FIG. 3).

In order to enable the bobbin diameter of the bobbin 15 to grow during the winding travel in the winding area, the pressure roller 10 and the traversing device 3 are moved away in the vertical direction by means of the slide 12. This movement is controlled by the relief device (not shown here).

The winding machine has a thread deflection device for placing the thread on an empty tube or for turning the thread from a full spool to an empty tube. The thread deflection device consists of a guide plate 24 which is movably arranged on the circumference of the grooved roller 8. Furthermore, the thread deflection device has a thread guide 11 arranged in the thread run in front of the traversing device 3, which can be positioned axially parallel to the winding spindles 17 and 18 by means of a positioning device 42. In Fig. 1 the dishwasher is shown in the operating position. The guide plate 24 is in a rest position. In this position, the area of the pressure roller 8 that is not contacted by the thread is covered entirely or partially by the guide plate 24. The thread guide 11 is also in a rest position lying outside the traversing triangle.

When it is first put on, the winding spindle 17 with the sleeve 16 is first pivoted by rotating the winding turret 20 into the position shown in the winding area — as shown in FIG. 1. The carriage 12 then moves down to bring the pressure roller 10 into contact with the sleeve 16. The sleeve 16 is driven by the winding spindle 17 so that the pressure roller 10 assumes the same peripheral speed when it comes into contact with the sleeve 16. The guide plate 24 is then turned counterclockwise in the direction of movement indicated by the arrow pivoted into the thread path between the pre-traversing unit 4 and the grooved roller 8. The thread is gripped by the leading edge 25 of the guide plate 24 and guided out of the traversing thread guide 7 and out of the thread guide groove 9 of the grooved roller. The thread thus comes out of the traversing device. It is placed around the guide plate 24 with a feed gun and guided between the empty sleeve 16 and the empty sleeve 19. The thread will take its natural running direction, so that it is located in the central region of the sleeve 16. The direction of movement of the thread 1 is opposite to the direction of movement of the empty tube 16 indicated by the arrow. Now the thread guide 11 is pivoted from the rest position into a catching position by means of the positioning device 42. The thread guide 11 picks up the thread 1 and guides it along the leading edge 25 into the catching position. The catching position is outside the traversing area. Here, the thread guide 11 lies in a normal plane with a catch slot made in the sleeve 16. Now, by guiding the feed gun by the operator, the looping of the thread 1 on the empty tube 16 can be increased such that the thread is caught in the catch slot of the empty tube 16.

However, it is also possible to give the thread 1 a specific wrap on the sleeve 16. For this purpose, a contact plate 26 arranged on the side of the machine frame is used. The contact plate 26 is fastened to the end of a swivel arm 27. The other end of the pivot arm 27 is pivotally mounted on a pivot axis 28 arranged in the upper machine frame 22. The swivel arm 27 can be swiveled by a drive (not shown here) in such a way that the contact plate 26 can enter the region of the winding turret 20. Then the contact plate 26 is pivoted between the sleeve 16 and the empty sleeve 19. A leading edge 29 of the contact plate 26 deflects the thread 1 in such a way that the thread 1 wraps around the sleeve 16. When the contact plate 26 is in the operating position is located and the thread guide 11 is moved into the catching position, the thread is caught in the catching slot of the sleeve 16.

After the thread is caught in the catch slot of the sleeve 16, the thread guide 11 is guided in such a way that a thread reserve can be wound on the sleeve 16. After the thread reserve has been laid, the thread guide 11 moves back into its starting position. At the same time, the guide plate 24 is pivoted into its rest position, so that the thread falls into the traversing device and is taken over by the traversing thread guide 7 and the thread guide groove 9. The contact plate 26 is also pivoted into its rest position. The winding cycle for forming the coil 15 begins.

During the winding cycle, the speed of the winding spindle 17 is controlled by means of a control device such that the peripheral speed of the coil 15 remains constant. For this purpose, the speed of the pressure roller 10 is detected and a control device is given. As soon as the speed of the pressure roller 10 changes, the spindle drive 36 of the spindle 17 is adjusted via the control device, so that the peripheral speed of the pressure roller adjusts itself to its target value.

When threading it is also possible that the thread guide 11 transfers the thread to a thread reserve device at the end of the traverse stroke. The thread reserve device then guides the thread during catching and during the formation of the thread reserve. The thread reserve device then releases the thread.

In Fig. 2 is the situation when threading from the full bobbin to one

Empty sleeve shown. After the coil 15 is fully wound, the carriage 12 moves to its uppermost position. The winding turret 20 is against the Swiveled clockwise in direction of rotation 23. After the full spool 15 has left the area of the grooved roller 8, the carriage 12 is lowered. Now the guide plate 24 is pivoted from its rest position into the operating position. For this purpose, the guide plate 24 is connected to a rocker 43 (FIG. 3) which is pivotably arranged on the carriage 12. Then the leading edge 25 of the guide plate 24 guides the thread 1 from the traversing thread guide 7 of the pre-traversing unit 4 and from the thread guide groove 9 of the grooved roller 8. The thread 1 assumes its natural thread running direction, which lies approximately in the middle of the bobbin 15. Thus, a first binding bead is first wound.

When the winding turret 20 is pivoted, the winding spindle 17 with the full bobbin is moved in the axial direction from an inner position to an outer position on the winding turret 20 — as will be described in more detail later in FIG. 3. The outer position is reached when the winding spindle 17 with the full bobbin 15 has reached the changing range, as shown in FIG. 2. The winding spindle 18 with the empty tube 19 and the winding spindle 17 of the full spool 15 are offset from one another on the winding turret 20.

In Fig. 3 the situation of Fig. 2 is shown in the front view. In the embodiment of the winding machine shown in FIG. 3, several winding stations are shown by way of example - four winding stations are shown. Each of the winding stations has the same structure, so that the description based on a winding station - as before - is continued.

The winding spindles 17 and 18 are slidably mounted with the spindle bearings 31 and 32 in the winding turret 20. The winding turret 20 is mounted with bearings 38 in the machine frame 21. On the side of the winding turret 20 opposite the winding stations, the winding spindle 17 is connected to the spindle drive 36 and the winding spindle 18 is connected to the spindle drive 37. In the area around the drive 36 and the bearing 31, a cam 33 is arranged on the winding spindle 17. The cam 33 engages in a groove 34 in the machine frame. The groove 34 is arranged circumferentially in the machine frame, the groove course preferably being partially inclined to the vertical. Thus, the winding spindle 17 with the cam 33 relative to the winding spindle 18, which is also guided with a cam 35 in the groove 34, is moved axially from an inner to an outer position on the winding turret.

The following description of folding the thread applies to both FIG. 2 and FIG. 3. After the winding spindle 17 with the full bobbin 15 has reached the position in the changing range, the thread guide 11 is moved from its rest position into a catching position by a positioning device 41 method. Here, the thread is gripped by the thread guide 11 and slides along the leading edge 25 of the guide plate 24. In this position, another binding bead is wound on the full spool 15. The empty tube 19 on the winding spindle 18 is only slightly looped by the thread 1. Catching is not possible in this situation. Only after the contact plate 26 has been pivoted from its rest position into the operating position, as shown in dashed lines in FIG. 2, is the wrap of the thread 1 on the sleeve 19 increased such that the thread 1 dips into the catch slot 41 of the empty sleeve 19 and is caught. The contact plate 26 is not shown in FIG. 3 due to the clarity. The thread then breaks in the section between the full bobbin 15 and the empty tube 19. The feed plate 26 is now designed such that the entire length of the full bobbin 15 is covered. Thus, the loose thread end of the full bobbin 15 cannot get into the area of the empty tube 19.

After the thread 1 is caught on the empty tube 19, the thread guide 11 is positioned such that a thread reserve can be deposited on the tube is. If the thread reserve is wound, the guide plate 24 and the thread guide 11 move back into their starting position. The thread 1 is thus released and reaches the areas of the thread guide groove 9 of the grooved roller 8 and the traversing thread guide _c 7 of the pre-curling 4. The new winding cycle begins.

The winding spindle 17 with the full spool 15 is braked so that the full spool 15 is ready for removal. After the full spool 15 has been cleared of the spindle 17, the contact plate 26 swings back into its starting position. One or more new empty tubes are plugged onto the winding spindle 17.

When threading it is also possible to guide the thread by means of the thread guide 11 and a thread reserve device arranged outside the traverse stroke. Here, the thread is moved by the thread guide 11 only for transfer to the thread reserve device from the traverse stroke area. The positioning for catching and forming the thread reserve is carried out by the thread reserve device.

In the catch position, the thread runs parallel through the catch slot 41 of the empty tube 19. The parallel thread run and the opposite directions of movement of the thread 1 and the empty tube 19 lead to a very high degree of catching security.

4 shows a further embodiment of the winding machine according to the invention in a side view. The construction here is essentially identical to the construction of the winding machine in FIG. 1. Compared to the winding machine in FIG. 1, in the dishwasher shown in FIG. 4, the guide plate 24 is arranged in such a way that the direction of movement for pivoting into an operating position is clockwise he follows. The winding spindles 17 and 18 are not displaceably mounted on the winding turret 20. The direction of rotation of the turret is also aligned with the direction of rotation of the winding spindles. Therefore, when threading from the full bobbin 15 to the empty tube 19, the winding spindle 18 with the empty tube 19 is pivoted into the thread path in such a way that the direction of rotation of the tube 19 and the running direction of the thread 1 are the same. With this arrangement, the empty tube 19 has a loop which is already required for catching the thread in the winding area.

When changing the thread, the carriage 12 is first moved to an uppermost position so that the winding turret can move the full bobbin 15 clockwise from the winding area into the changing area. After the full bobbin 15 is positioned in the changing area, the guide plate 24 is moved into its operating position so that the leading edge 25 of the guide plate 24 lifts the thread out of the thread guide groove 9 and the traversing thread guide 7. The thread then runs again in its natural course in the central region of the full bobbin 15. Now the feed plate 26 is pivoted between the empty sleeve 19 and the full spool 15 by means of the swivel arm 27. The contact plate 26 has a guide groove 30 facing the thread, in which the thread is caught. In this position, a binding bead is formed on the full spool 15. Now the thread guide 11 moves from its rest position into the catching position. The thread 1 is moved out of the area of the traversing stroke until the thread 1 passes through a catch slot in the empty sleeve 19. After the thread 1 has been caught by the empty tube 19, the thread reserve is formed. Then the winding trip begins. In this embodiment of the winding machine, too, the thread is guided out of the traversing device in such a way without substantially changing its wrap in the area of the grooved roll.
