Definitions
- the invention relates to a combing machine with a device to guide the working organs of the combing machine in a desired angular position.
- a combing machine has a plurality of reciprocating or not constantly revolving working members such as pliers, fixed comb, pair of feed rollers and two Abr facedwalzencrue. To be able to adjust these working organs exactly in their working position and in their functional sequence, it is necessary to sensitively bring the comber into several, well-defined working positions, which are connected to certain rotational angular positions of the comber, that is, with the angular position of their circular comb.
- From the DE 195 09 209 A1 is a combing machine with highly loaded, highly dynamic to be driven unit with characteristic torque curve known, which has a position-actual value transmitter, the field-oriented controls controls other drive motors assigning manipulated variables as position-target values.
- a drive motor and a position-actual value transmitter is also used in the device according to the invention.
- the upper nipper is mounted on a statically displaceable by a motor or dynamically adjustable axis.
- DE 195 06 351 A1 discloses a comber having means comprising a rotational angle initial value interrogator on a component participating in the rotary motion of the comb machine and a controller for urging the comber drive motor.
- the invention was therefore the task of bringing the combing machine automatically in a given her angular position or to be able to watch their functioning accurately.
- the comber can be given a desired angular position or a specific function sequence can be specified.
- the rotation angle position actual value interrogation device detects the actual rotation angle position of the comber.
- the comparison device the desired rotational angle position and the actual rotational angle position are compared and, in the event of a deviation between these values, an actuating signal is output to the control device which acts on a drive of the comber in order to reduce the deviation.
- the acted upon drive of the comber may be their normal drive motor. In some cases, it may also be useful to equip the comber with an auxiliary drive motor, which can drive them at a reduced speed. By means of such an auxiliary drive motor targeted rotation angle positions can be approached more accurately.
- Such an auxiliary drive motor is connected via a speed-reducing gearbox with the combing machine. Since such a transmission would be overloaded at the usual operating speed of a comber, its engagement during normal operation can be solved. Alternatively, a freewheel can be switched on between the auxiliary drive motor and the combing machine transmission, which allows the transmission to be overtaken by the main drive.
- an embodiment of the invention is shown schematically. It shows the front view essential working organs of the comber with the organs of the device according to the invention.
- the combing machine has a gearbox 1 through which its essential working members are driven.
- the extensive gear not only causes the rotary drive of various working organs, but also their spatial displacement.
- These essential working organs are a circular comb 2 which constantly revolves during operation of the comber and whose comb segment 3 is indicated, a fleece tongs 4 movable back and forth, an intermittently rotated feed roller pair 5, an upwardly and downwardly movable fixed comb 6 and two pairs movable back and forth and intermittently rotated Abr complicatwalzen 7.
- the drive of the transmission 1 is effected by a main drive motor. 8
- an angular position actual value interrogation device in the form of a rotational angle position sensor 9 which scans the rotational angle position of the circular comb.
- the circumference of the circular comb is provided for this purpose with indicators not shown here.
- the rotational angle position sensor 9 may also be associated with another component of the comber, which participates in the rotational movement.
- a working cycle of the comber which corresponds to one revolution of the circular comb 2, can be divided into, for example, 40 steps of 9 ° by the indicators. In some cases, even a finer subdivision of a work cycle may seem appropriate or unevenly subdivided steps may be assigned to specific, characteristic steps of a work cycle.
- the signal value of the rotational angle position sensor 9 is fed as an actual value to a comparison device 10, to which a control value of a selector 11 is also supplied as the desired value.
- This dialer may be equipped with an alphanumeric input keyboard 12 and a display 13. The input keyboard is set up to specify desired rotational angular positions of the circular comb 2 or to switch it stepwise or to let it run slowly forward or backward.
- the comparison device 10 compares the actual rotational angular position of the circular comb 2 with the predetermined rotational angle position predetermined by the selection device 11 and outputs in the case of deviations between these values, an actuating signal in the sense of reducing this deviation to a control device 14. This acts on the drive motor 8 of the circular comb 2 and moves the comber in the position corresponding to the desired position. In this position settings can then be made or checked on the comber and their organs.
- an auxiliary drive may be provided in the form of an auxiliary drive motor 15 which allows the comber to be driven more slowly and with which certain angular positions are more precisely approachable.
- a stepper motor with a reduction, through which the circular comb axis 2 is rotated by increments of, for example, 1 ° during each rotation step of the stepping motor.
- a freewheel can be turned on, which allows the drive of the comber by the drive motor 8 in operation at high speed. However, this eliminates the need to rotate the circular comb backwards. To open up this possibility would have waived the freewheel, the engagement of the auxiliary drive motor during normal operation of the combing machine with operating speed.
