Embodiment Construction

[0053] Correspondingly schematically shown in the figure is a circuit diagram for controlling a yarn splicing device of a textile machine for producing cross-drums, with a device according to the invention for monitoring the function of a solenoid valve of the yarn splicing device.

[0054]FIG. 1 here shows a preferred embodiment of the invention, in other words a pressure sensor is temporarily inserted in a compressed air distribution line, said pressure sensor being connected to a portable control unit.

[0055] FIG. 2 shows another embodiment of the invention. In this embodiment, a fixed pressure sensor is installed in the compressed air distribution line, which is connected to the central control unit of the textile machine.

[0056] As can be seen from the figure, each of the large number of cross-drum robot working stations, marked A, B, etc., has its own yarn splicing device, generally indicated by reference numeral 1 in the figure. Such a yarn splicing device 1, as de...

Abstract

The system to monitor the function of electromagnetic valves, at a pneumatic yarn splicer (1) for a cross wound bobbin winder, has a pressure sensor (12) to register a temporary pressure drop in the pressure lines (3,15) serving each electromagnetic valve (5,14). The pressure drop is converted into a proportional electrical signal (i) to be passed to a control unit (19,22). The signal is matched against a comparative value to determine the functioning of the electromagnetic valves, and the results are displayed (28).

Description

technical field [0001] The invention relates to a method for checking the function of a solenoid valve for controlling a pneumatic yarn splicing device in a working position of a textile machine for the production of cross-drums. The invention also relates to a device for carrying out the method described above. Background technique [0002] Pneumatic yarn splicing devices have long been known in the textile industry, for example in relation to cross-drum robots. In the operating positions of such known and commonly used textile machines, the textile bobbins produced, for example, on ring spinning machines are wound into bulky cross-drums. [0003] When winding, check whether the running yarn has yarn defects at the same time. The detected yarn defects are cut off, and the resulting yarn ends are reconnected by the yarn splicing device. [0004] With the known yarn splicing devices it is possible to achieve yarn splicings which are very close in quality (firmness and appe...
