Abstract: A cheese-producing textile machine (1), having a central control unit (37), a plurality of work stations (2), and a service unit (23), which automatically supplies the work stations (2). The work stations (2) each have a winding device with a winding drum (17), which is individually driven by a motor, and a work station computer (39). The central control unit (37) is connected via a machine bus (40) with the work station computers (39) and with a control device (39) of the service unit (23). Specific winding drum data (x, y), in particular the number of traverses (g) of the winding drum (17) of the work stations (2), are stored in a memory, e.g., integrated in the central control unit (37). During the yarn pickup by means of the yarn lifter (41) of the service unit (23) in the course of a cheese change, the individual electric motor drive (50) of the winding drum (17) is controlled to match the number of revolutions of the winding drum (17) to the number of traverses (g) thereof.

Abstract: A method for operating a cheese-producing textile machine (1), having a plurality of aligned work stations (2), a transport device (21) extending over the length of the machine for removing finished cheeses (11), and a cheese changer (23) displaceable above the work stations with an ultrasound sensor device (30) connected to the control device (38) of the cheese changer (23) for monitoring the loading state of the transport device (21). The sensor device (30, 38) is initially set to the climatic conditions of the respective place of employment by processing appropriate reference sound signals, i.e. a correction factor is determined. During operation, scanning values (TW) are then determined by means of the traveling time of the measuring sound signals of the ultrasound sensor (30) which, taking into consideration the respectively prevailing climatic conditions, permit conclusions regarding the loading state of the transport device (21) in the deposit areas of the respective work station (2).

Abstract: A cheese-producing textile machine 1 with a central control unit 37 and a plurality of winding stations 2 which are serviced by an autonomously operating service unit 23. The central control unit 37 of the textile machine 1 is connected via a machine bus 40 with individual winding station computers 39 as well as with a control device 38 of the service unit 23. Control programs A, B, C, D, etc. are stored in the control device 38 of the service unit 23, and are specially adapted to various respective structural configurations of the service unit 23. It is possible in a simple manner to activate the control programs A, B, C, D, etc. in correspondence to the particular prevailing structural configuration of the service unit 23 by means of appropriate software encoding via an input element 41 on the central control unit 23.

Abstract: A cheese-producing textile machine 1 has a plurality of winding stations 2 and a service unit 23 for servicing the winding stations 2. The textile machine 1 has a central control unit 37 as well as separate winding station computers 39 for the individual winding stations 2. The service unit 23 has a control computer 38 which is connected by a machine bus 40 with the central control unit 37 as well as with the winding station computers 39. During the process of exchanging a cheese with an empty bobbin performed by the service unit 23, the yarn tensioner 14 of the respective winding station 2 is actuated via the machine bus 40 in accordance with the control computer 38 of the service unit 23, to set the tension of the yarn 30 optimally according to the respectively existing processing conditions.

Abstract: A cheese-producing textile machine 1 having a plurality of winding stations 2 with respective separate winding station computers 39 and a unit 23 for servicing the winding stations 2. The textile machine 1 has a central control unit 37 and the service unit 23 has a separate control computer 38. These control devices 37, 38 and 39 are connected with each other by means of a machine bus 40. During the process of replacing a finished cheese with an empty tube at any winding station, a cheese brake integrated into the winding creel 18 and/or a creel lifting device 49 can be actuated by the service unit computer 38 via the machine bus 40 in a pulsed manner when needed, for example to dislodge a cheese 11 which is stuck in the winding creel.

Abstract: An automatic package doffer of a textile winding machine includes a yarn engaging device and a travel limiting device. The yarn engaging device includes a pivot housing and a movably hinged yarn lifter head and is seated on a pivot and bearing shaft in a partially rotatable and axially displaceable disposition. A yarn catcher plate, clamping shears, and a yarn guide plate are disposed on the yarn lifter head. The yarn engaging device also includes a stop element for engaging the housing of a respective winding station for stopping movement of the yarn engaging device at a first predefined position with respect to the winding station housing. The travel limiting device includes a clamp assembly that is clampable to the yarn engaging device when at the first predefined position and guide rails attached to the doffer upon which the clamp assembly is slidably disposed. A pneumatic cylinder selectively causes the clamp assembly to clamp onto a braking tube that is part of the yarn engaging device.
