Abstract

A control system for a multished weaving machine includes one or more scanners (9) for checking faults and adapted to generate a danger signal on fault detection, a main signal generator (1) adapted to generate a starting signal, a speed pulse generator (2) to be started by the starting signal and to generate speed signals for controlling the machine, a braking signal generator (5), and an output unit (6) controlled to brake the machine on receipt of a locking signal initiated by the danger signal. <IMAGE>

BACKGROUND OF THE MANAGEMENT OF THE MULTIPLE SHEAR WEAVING MACHINE

BACKGROUND OF THE INVENTION The present invention relates to the control of a multi-shed weaving machine. The invention is based on the interconnection of the control circuits, the machine dangerous state sensors, the stop system block, the reset blocks and the output block so that the wiring operates reliably and quickly and in case of failure it is easy to identify the fault. The invention can be used to control textile 1, in particular multi-sheath weaving machines.

- 2 machine functions are connected to the first, second and third outputs of the output block by their first, second and third outputs, and the second input of the speed control block is connected to the output of the reset block, the fourth input is connected to a bypass whose output is connected to the third input of the machine function evaluation block.

The advantages of the control system of the multi-shred weaving machine according to the invention are, in particular, the rapid response of the control system to the instantaneous state of the machine, higher reliability of the control system and greater operator safety. It is also an advantage that, in the event of failure of any part of the wiring control system according to the invention, it ensures that the machine cannot be started before the fault has been eliminated. In addition, the circuitry according to the invention provides clear indication of a possible fault and clarity in its determination.

The control wiring of the multi-shed weaving machine according to the invention will be described below with reference to the attached drawing. Input block 1 is connected with its first output to the first input of the speed control block 2 and to the second input of the bypass block 2 and its second output is connected to the micro-feed block 4 and to the third input of the bypass block 2. The speed selection control block 2 is connected by its first and second outputs to the first and second inputs of the machine function evaluation block, which is connected to the first, second and third inputs of the output block 6 by its first, second and third outputs. connected to the fourth input of the machine function evaluation block 2 and to the second input of the resetting block 7, the first input of which is connected to the sixth input of the machine function evaluation block 2 and the output

3 231 628 of the emergency system block 8, the input of which is connected to the output of the machine hazardous state sensor 6 and to the fourth input of the bypass block 2. The third input of the machine function evaluation block is connected to the output of the bypass block 2 and the sixth input of the machine function evaluation block 6 is connected to the first input of the reset block 6 and the output of the stop system block 10. The resetting block £ is its own. the fourth input is connected to the output of the initial reset circuit 11 and the first input of the bypass block, and its output is connected to the second input: Speed Selection Control 2.

In operation, the input block 1 sends a start pulse 12 to the speed selection train 2, which generates a pulse 13 the technological speed or the operating speed pulse 14, which are fed to block 5 to evaluate the function of the machine 6 is an operating speed pulse 15, an operating speed pulse 16 or a brake switch pulse 17. The input block 1 further comprises actuators shown to give a pulse 18 'at its second output, which is applied to a micro-feed block 4, which by its output pulse 19 ' operating speed in the machine function evaluation block £ and through the reset block £ resets the control block 2 by the rate of operation. An impulse 19 of the micro-feed block 4 applied to the fourth input of the machine function evaluation block 2 causes a pulse to appear at the second input of the machine function evaluation block. 15 technological speed. The stop system block 10 with its output pulse 20 of the stop system block 10 blocks the passage of the process speed pulses 13 and 14 and the operating speed in the evaluation block 2.
