Problems solved by technology

Yarns used for weaving are often divided into several groups, and each group of yarns is erected on 4-6 warp drop beams through warp stoppers. Therefore, hundreds of yarns will be erected on each warp drop beam, and workers still need to Locating broken yarn among thousands of warp droppers, it is not enough to indicate the position of the warp drop beam

no. 1 example

[0041] refer to figure 1 The menopause film shown in the present embodiment provides a kind of menopause film. The main body of the menopause film is made of metal materials. The yarn hole 17 communicates with the opening 18 , an LED lamp 11 is installed on the upper end of the beam-through hole 16 , and a wire 12 is arranged on one side of the beam-through hole 16 , and the LED lamp 11 is electrically connected with the wire 12 . An insulating region 13 is provided on one side of the opening 18 as a part of the negative electrode to form an electrical path.

[0042] In order to improve the conductivity, the conductive part of the wire 12 in this embodiment is made of copper wire.

[0043] The dropper provided in this embodiment is suitable for a loom with a safety stop unit, and after the loom stops, the voltage is switched by controlling the single-pole double-throw switch to re-supply power to the light-emitting element.

no. 2 example

[0045] Such as figure 2 For the menacea shown in the above example, the menacea provided in this embodiment includes at least two light-emitting parts, and the LED lights 14, 15 and the menacea body are bonded together with a paint film of epoxy resin material, which is applicable to The loom of the unit lowers the power supply voltage by controlling the single-pole double-throw switch to re-supply the light-emitting element.

[0046] The thickness of the menopause provided by the present invention is set to 0.2-0.5mm, which depends on the diameter of the warp and the density of the warp. Generally speaking, the larger the diameter of the warp and the higher the density, the thinner the warp should be set to reduce menopause. The friction between the sheets and between the warp yarns and the drop sheets due to mutual movement reduces static electricity.

no. 3 example

[0048] Such as image 3As shown, the present embodiment provides a broken yarn detection circuit, wherein the warp dropper provided by the first embodiment is used, and the loom equipped with a safety shutdown unit can automatically act as a light on the dropout wire without affecting the shutdown. The device provides a stable working voltage.

[0049] The control circuit includes a broken yarn self-stop controller 2, a warp stop beam 3, a stop signal receiving device 4 and a warp stop film;

[0050] The warp stop beam 3 includes a conductive peripheral body 31 and a conductive internal body 33, an insulator 32 is connected between the conductive peripheral body 31 and the conductive internal body 33, and the conductive internal body 33 and the conductive peripheral body 31 are all connected to the broken yarn automatically. The stop controller 2 is electrically connected, and several warp stoppers are erected on the warp stop beam 3 through the beam hole 16;

Abstract

The invention discloses a yarn breakage detection device and system and a detection method. A light-emitting part is arranged on a metal dropper, the outage shutdown function of a loom is reserved, and on the basis, a yarn breakage position can be accurately indicated when yarn is broken. A detection circuit is improved, when the dropper falls and makes contact with a dropper beam to form an electric access, a power supply voltage is switched from high voltage to low voltage, and a stable working voltage is provided for the light-emitting part while shutdown of the loom is not affected. According to the yarn breakage detection system, optical detection is conducted on a light source, the broken yarn is automatically positioned, broken ends of the broken yarn are sucked out through a brokenyarn suction unit, the workload of workers is reduced, and the textile production efficiency is effectively improved; the detection device can be directly and additionally arranged on the existing loom, and the loom does not need to be greatly changed; the implementation cost is relatively low, the idle time of the loom due to shutdown is reduced, and meanwhile, the weaving productivity and the weaving efficiency are improved.

Description

technical field [0001] The invention belongs to the field of textile machinery, and in particular relates to a yarn break detection device, system and detection method thereof. Background technique [0002] In the process of textile production, warp yarn breakage will inevitably occur, which greatly affects the production efficiency of textile production. Now most of the looms are equipped with stoppers to solve the problem that the machine cannot be stopped after the yarn breaks. The power failure of the loom After the shutdown, the workers in the workshop will locate and repair the broken yarn. This process is completely done manually. There are hundreds of thousands or even tens of thousands of warps for large-scale weaving, and the efficiency of yarn break location depends on the experience of workers and the density of yarn, so that manual positioning and repair will consume a lot of time. The existing method of positioning broken yarn by adding an indicator light on t...
