Problems solved by technology

Although the structure of this sensing device is relatively simple, it requires that the tension of the thread should not be too small, otherwise the shading sheet will fall off by mistake due to insufficient tension, especially when the tension fluctuates greatly, the sensing errors will increase significantly; at the same time, each time The wiring needs to pass the silk thread through the hook hole, which is inconvenient to operate; in addition, this kind of device is completely exposed, and it is easy to make the silk thread hang eastward and westward during operation, causing unnecessary troubles, and this exposed device is also vulnerable to external light. Errors caused by interference; moreover, this device can only implement single-wire sensing and cannot meet the requirements of simultaneous working sensing of multiple wires

Embodiment 1

[0024] Embodiment 1: (Assembly installation of disconnection self-stop photoelectric sensor device)

[0025] The material that each other part of the present invention adopts is that the photoelectric transmitter seat 21, the light guide seat 27, the photoelectric receiver seat 31, the half sleeve 26, the shading sheet seat 6 and the butterfly-shaped fixing card 4 are made of ABS plastic; The sheet 17 and the shading sheet 13 are stamped with 0.2mm thick phosphor bronze skin and punched with reinforcing ribs; the booster empty tube 9, the fork-shaped wire guide 5 and the wear-resistant needle 12 are made of alumina or titanium oxide materials Guide wire disc 29 and guide wire waist sheet 28 are stamped with 1.2mm stainless steel plate; Needle shaft 15 is made with No. 4 sewing needles.

[0026] The outer contour size of the light guide seat 27 is 106 mm long × 45 mm wide × 38 mm high, and the inner light hole diameter is 9 mm; the outer contour size of the photoelectric transm...

Embodiment 2

[0038] Embodiment 2: (the application of photoelectric sensing device on the digitally controlled wire stranding machine)

[0039] According to embodiment 1, the disconnection self-stop photoelectric sensing device installed and the J-shaped fixed frame 37 of the numerically controlled silk thread stranding machine, the frame fixed angle iron 42, the reciprocating intertwining mechanism 36, the electronic roughening device 38, and the automatic thread tension Regulator 39, tension adjustment counterweight 41 lead screw rod 40 etc. carry out assembling and connect electric wire and can put into operation (see Figure 9 ).

Embodiment 3

[0040] Embodiment 3: (Application of photoelectric sensing device on numerically controlled compound shaking machine)

[0041] The implementation method is the same as that of Examples 1 and 2, the difference is that each winding frame of the CNC re-oscillating machine only winds 5 pieces of wire at the same time, therefore, only 4 light guide seats 27 need to be installed to form 5 pieces of wires for simultaneous sensing and monitoring. The structure of a broken thread.

Abstract

The invention is a fiber break automatic stop photoelectric sensing device, comprising photoelectric emitter seat, photoelectric emitter, light guide seat, photoelectric receiver seat, photoelectric receiver, angle light shielding piece, and shielding plate; and it uses tension and friction force as winding fiber, lifts and moves up the angle shielding piece, and starts up when the light passes through, and after the fiber breaks, the angle shielding piece falls so that the light is blocked and it stops. And it is novel-designed, and reasonable-structured; and it is a closed light transmission system; it improves working efficiency; it is convenient to connect and change fiber; and it is applied to mechanical spinning industries of silk weaving, chemical fiber, cotton spinning, etc.

Description

technical field [0001] The invention relates to a control sensing device for automatic stopping of fiber threads in textile machinery, in particular to a photoelectric sensor automatic control device for automatic stop of fiber threads in textile machinery. Background technique [0002] During the winding process of mechanical processing, the fiber thread may be broken. At this time, the machine or winding device is required to stop immediately in order to connect the broken thread. Otherwise, the length of the thread will be unequal, which will affect the quality of the subsequent process. At present, many textile equipment have self-stop devices for thread breakage, but there are many sensing methods for thread breakage self-stop, and those with high cost have contact sensors (such as capacitive non-contact sensors, a set can only sense one Silk); moderate cost photoelectric and electrical contact sensors; low cost mechanical sensors. In the photoelectric sensing method, ...
