Problems solved by technology

It is conceivable that in the latter case the weft release time tends to vary, and thus the time difference occurs only in an insignificant manner, which makes it difficult to select a sub-nozzle pressure suitable for reducing the compressed air consumption and also depends on the sub-nozzle The selected value of the pressure may cause unstable weft insertion

Embodiment Construction

[0013] The following will refer to figure 1 and 2 A first embodiment of the display device of the air jet loom according to the present invention will be described. Note that the terms "upstream" and "downstream" appearing in the following description are used to indicate a direction or a relative position with respect to the direction in which the weft yarn is introduced into the ridge (and also the direction in which compressed air supplied from an external source flows) .

[0014] see figure 1 , the air-jet loom indicated by 1 comprises a weft insertion device 2, a plurality of sub-nozzles 5 and an end nozzle 6, the sub-nozzles and end nozzles are arranged at the weft insertion device along a reed 4 with a plurality of reed teeth 3 2 downstream. In this figure, the compressed air supply lines to the weft insertion device 2, the sub-nozzles 5 and the end nozzles 6 are also shown in block diagram form. The weft insertion device 2 has a main nozzle 7 and a tandem nozzle 8...

Abstract

There is provided a display device of an air jet loom that includes a weft insertion device causing a weft yarn released from a weft measuring and storing device to move by compressed air injected from a main nozzle and plural sub-nozzles arranged in the direction of weft insertion, a setting and measuring device that serves to set and measure pressure or flow rate of the main nozzle and also to set and measure pressure of the sub nozzle, and a controller storing the measured pressure or flow rate of the main nozzle and equipped with a display. The controller causes the display to show a line graph representing pressure or flow rate of the main nozzle with which weft insertion is completed at a previously set angular position of the air jet loom for each of different predetermined pressures of the sub-nozzle.

Description

technical field [0001] The present invention relates to a display device for an air jet loom. Background technique [0002] When fabrics are woven in the air-jet loom, empirically obtained data of weaving conditions based on given fabric conditions such as kinds of weft and warp are set in the air-jet loom in advance. For example, data of air injection pressure or air injection timing of main nozzles and sub nozzles of a weft insertion device suitable for stable weft insertion is set as spinning conditions. Recently there has also been a need to reduce the compressed air consumption at the main or sub-nozzles in order to provide energy savings in air-jet looms. [0003] Japanese Unexamined Patent Application Publication No. 5-51842 discloses that the timing of weft yarn release is detected by a weft yarn release sensor provided in the weft yarn measuring and storage device, and the timing of weft yarn arrival is detected by a sensor on the side of the reed opposite to the m...
