Definitions

  • the present invention relates to a drive system for driving an inertial mass.
  • Heald frames in weaving are reciprocated vertically through a linkage mechanism by means of rotating cams or crank motions on a common shaft, each selected by use of a clutch or other such power selection means.
  • the shape of the cams and/or the paths traced out by the crank motions when driven by the drive motor accelerates the heald frame from its lowest shedding position to a velocity which is then maintained over a period before the heald frame begins to decelerate towards its upper shedding position.
  • the heald frame decelerates towards its upper position under the action of gravity and is then driven down, accelerated and then decelerated, towards its lowermost shedding position with the assistance of gravity, its stored potential and kinetic energy is released back to the drive shaft.
  • This returned energy assists in accelerating other heald frames which are being moved from their lower to their upper shedding positions.
  • the drive motor can be a relatively low power motor.
  • the linkage mechanism of the heald frames typically provides a suitable mechanical advantage to allow a relatively low power drive motor to be used. This enables the heald frames to be driven at speeds up to 600 picks per minutes. However, to increase the speed of a heald frame substantially above this limit requires a very considerable increase in the power of the drive motor, rendering the system uneconomical. If the linkage is changed to provide a more direct drive to the heald frame, because of the inertia of the heald frame a considerable amount of electrical energy is generated in the drive motor as a result of the motor being "driven" by the heald frame during deceleration towards the end of the stroke of its downward shedding movement.
  • Figure 1 is an idealised graph of velocity against time for movement of a heald frame from its lower extreme shedding position to its upper position during a shedding movement.
  • the graph for the return movement of the heald frame from its upper shedding position to its lower shedding position is identical to Figure 1.
  • This is an ideal motion diagram and shows that maximum power is required from the drive motor only during the acceleration period r ⁇ from time t t to t,.
  • the present invention seeks to provide an improved drive system for driving an inertial mass.
  • the present invention provides a drive system for driving an inertial mass over a drive path between first and second extreme positions, comprising:
  • linkage means connecting said drive motor to said mass for driving said mass
  • control means for applying electrical power to said drive motor thereby to accelerate said mass over a first portion of its drive path from one of said first and second extreme positions;
  • control means connects said drive motor to said storage means whereby when said drive motor acts as an electromagnetic brake during deceleration of said mass over a second portion of its drive path towards the other of said first and second extreme positions said drive motor serves to charge said storage means.
  • Figure 1 is a graph showing velocity against time for the ideal movement of an oscillating mass driven along a drive path between two extreme positions;
  • Figure 2 is a graph similar to that of Figure 1 with friction and damping forces taken into account
  • Figure 3 is a graph similar to that of Figure 1 additionally showing velocity against time for the ideal movement of a reciprocating mass such as a heald frame of a weaving machine, the heald frame being driven by a preferred form of drive system according to the present invention

  • Figure 5 is a diagrammatic representation of the steps of operation of the drive system according to the present invention using relative positional feedback for the drive control;
  • Figure 6 is a diagrammatic representation similar to that of Figure 5 using analogue absolute positional feedback for the drive control
  • Figure 7 is a graph similar to that of Figure 3.

  • This enables very low power motors to be used to drive the heald frames directly and in rum the heald frames can be made relatively lightweight.
  • actuators such as brushless servo motors (which can be accelerated very rapidly up to the required heald frame velocity) can be used. This reduces both the acceleration and deceleration time periods for the heald frame and thus enables an increase in the weaving speed.
  • the control system has a microprocessor 16 which controls the actuation of each actuator 12, 14 individually, thereby controlling the weaving process, according to a preselected weaving programme.
  • the microprocessor 16 determines the selection of heald frames and times the selection and the movement of the weft thread.
  • Control signals from the microprocessor are passed to an actuator controller 18 which monitors the power drawn by each actuator. This indicates whether or not each actuator (and thus each heald frame) is being accelerated from one of its extreme lowermost or highermost shed positions.
  • the actuator controller 18 is also connected to an electrical power storage means, preferably in the form of a capacitance 20, in turn connected both to a storage monitor 22 and an electrical power controller 24.

  • the position signal which is supplied by the microprocessor 16 to the error calculation logic circuit 100 varies over the cycle of movement of the actuator and its rate of change represents the acceleration and deceleration of the actuator and thus of the heald frame.
  • the circuit is thus monitoring the velocity of the actuator and comparing it with a desired velocity set by the microprocessor 16 by virtue of the change with time of the position signal from the microprocessor 16 and the comparison of the difference position signal with the pre-selected reference value.
  • the comparison gives the indication of the velocity and acceleration of the linear actuator 12 and, in dependence upon the comparison of the different signal with the reference value, the logic circuit 120 applies a further error signal to a speed calculation circuit 122.
  • the latter also receives a signal from the store 118 indicating the current position of the linear actuator and thus of the heald frame within its cycle.
  • the speed calculation circuit 122 uses the signals to determine whether or not the heald frame should be maintained at a constant speed, accelerated or decelerated and applies a resulting signal to the output selection logic 102 to maintain the linear actuator at the same speed or accelerate or decelerate the actuator accordingly.
  • the position signal from the store 118 is also fed to a polarity and coil selection circuit 124 which determines the direction of movement of the linear actuator 12 and thus the heald frame in dependence on this position signal and accordingly applies a directional signal to the output selection logic circuit 102 which either maintains the actuator 12 moving in the same direction or reverses its direction.
  • Figure 6 shows a simplified control system in which the position sensor 28 on the actuator 12 supplies a position signal to a subtractor 200. This compares the signal with a desired position signal from the microprocessor 16 and applies a resulting error signal to a polarity and coil selection circuit 202, the output of which is applied to the drive circuits 108, 110 for the coils of the actuator 12.

  • the error signal generated by the error calculation logic 100 is also fed back to the microprocessor 16 where it is compared with a pre-set reference level. If the error signal exceeds the pre-set reference level this indicates that the speed or acceleration of the actuator 12 is not meeting the desired value and the current applied to the actuator coils is therefore approaching an unacceptable level. This may be as a result of a breakdown in the mechanical equipment or increased friction forces. If this occurs then the microprocessor 16 applies a current limit to the coil drive circuits 108, 110 to prevent the applied current reaching unacceptably high levels.
  • FIG. 3 A velocity against time graph is shown in Figure 3 which compares the idealised conventional drive system (curve A of Figure 1) with that of the described embodiment of the present invention (curve B).
  • the actuator controller 18 monitors the speed of the actuator in the manner described above and compares this with a desired speed v, which is set by the variation in the desired position signal from the microprocessor 16. Since initially the speed of the actuator 12 and therefore the heald frame is less than v ; the controller 18 applies power to the actuator to increase the actuator speed. However, the acceleration of the actuator 12 is maintained within certain limits (such as set by the slope 30 of the curve B) by the reference value which is set by the microprocessor 16 and compared with the difference signed in the logic circuit 120.
  • This reference value is increased by the microprocessor 16 at a pre-selected rate from a first minimum preset value to a second maximum preset value. This ensures power is supplied to the actuator 12 at a controlled rate to ensure a steady acceleration of the actuator 12 at a pre-selected rate.
  • the reference value reaches the second preset value which is a maximum set by the microprocessor 16, and is held at that value. This has the effect of preventing further acceleration of the actuator 12 which then continues at the desired velocity v
  • the reference value is maintained at its maximum value over the time period t' e in order to maintain the velocity of the actuator 12 and thus the heald frame at v ; .
  • the microprocessor 16 begins to reduce the reference value from its maximum value back towards the first preset value. This reduces power to the actuator 12 at a relatively constant rate and thus decelerates the actuator 12 in a controlled manner.
  • the actuator 12 is acting an electromagnetic brake on the heald frame and is therefore generating electrical power.
  • the excess power which is generated by the actuator is fed by the controller 18 to the power capacitance 20 for storage.
  • the actuator 12 is then accelerated in the reverse direction and the cycle is repeated in the same manner as previously described. Again, when the actuator is decelerated towards the lowermost shed position of the heald frame electrical energy is generated by the motor and this is again stored in the power capacitance 20.
  • the actuator controller 18 monitors the power required by each actuator and where this rises above a threshold, supplies power from the power storage means 20.
  • the level of the power capacitance 20 is momtored by the monitor 22 such that if the power capacitance level drops below a certain level the momtor 22 switches mains power from the mains supply through the power controller 24 into the capacitance to top it up.
  • the power returned to the system by each actuator will initially be below a threshold which is monitored by the monitor 22. Whilst this power level is below the threshold none is returned to the power capacitance, it being used by the system to bring the machine up to operating speed as quickly as possible.
  • the power level returned to the system by the actuators 12, 14 rises above the threshold of the monitor 22 it is channelled to the power capacitance. When power is required by any one of the actuators it is transmitted to the actuator by the actuator controller from the power capacitance.
  • the energy required to be drawn from the mains can be reduced considerably, and under certain energy imbalance conditions energy may be regenerated and returned to the mains to reduce further the overall energy costs.
  • the invention can also be applied to flat bed and circular knitting machines, needle boards of needling machines, needles of tuft machines, yarn winding machines and any other machines in which an inertial mass is driven in an oscillating manner such as in a simple harmonic motion or any compound motion of variable strokes and frequencies.
  • Figure 8 shows a further simple form of motion for a heald frame which is sinusoidal. It will be appreciated that each of the above forms of motion can be applied to any inertial mass oscillating between two positions.
