Operating device of weaving machine

Abstract

The present invention relates to an operating device of a loom which comprises a setter for setting at least one parameter, and a controller which, when an operation signal is inputted, makes the loom perform a low-speed normal rotation process for normally rotating the main shaft of the loom at a low speed and then a blank beating operation process without accompanying weft insertion while actuating the loom, and subsequently, shifting the loom to an ordinary operation process accompanying weft insertion. In the setter, it is possible to manually set the termination time of at least one of the low-speed normal rotation process and the blank beating operation process as the parameter. For preventing the thickness segment, the invention can set each period of the low-speed normal rotation process and the blank beating operation process properly.

Description

technical field [0001] The present invention relates to a device for starting a stopped loom and operating a loom. Background technique [0002] As one of loom operating techniques for starting a loom that has stopped, there is an operating method (Patent Document 1) in which the main shaft of the loom is reversed at a low speed from the current position to a predetermined position when the loom operation is started (Patent Document 1). position, then start the loom, and only make the loom perform an empty run without weft insertion (i.e., dummy weaving operation) corresponding to the reverse amount, and then make the loom change to a weaving operation with weft insertion. The so-called normal operation method of operation. [0003] Another technique that is a loom operation technique for starting a loom that is stopped is to perform dry running of the loom without reversing at the start of loom operation, and then turn the loom to normal Operation method of operation (pat...

Problems solved by technology

As a result, when stretchable weft yarns are used, slack occurs in the weft yarns exposed to the cloth fell, which becomes a fabric defect

[0010] In addition, the operating method of Patent Document 2 cannot be applied to shedding devices other than electronic dobby devices (for example, crank shedding devices, cam shedding devices, etc.) that perform shedding movement in a predetermined mechanically determined selective shedding mode.

[0011] In addition, with the operating method of Patent Document 3, since the number of idle beatings after the loom is started is limited to one time, there is no degree of freedom in setting the number of idle beatings like the techniques of Patent Documents 1 and 2, and it is impossible to reliably eliminate thick and thin sections.
