High-reliability socks knitting machine

Abstract

The invention provides a high-reliability socks knitting machine. A broken yarn detection sensor is additionally arranged; the device can be used for reasonably distributing yarns and the detection sensitivity is guaranteed; the high-reliability socks knitting machine is compact in structure, and a broken needle detection device has relatively high sensitivity, can be used for detecting a broken needle phenomenon without axial movement and can automatically quit when detection is not needed; a limited socks knitting working region does not need to be excessively occupied, and broken needle and broken yarn phenomena are effectively detected, so that the reliability of the socks knitting machine is improved, the generation of defective products is reduced and the production cost is reduced; meanwhile, the high-reliability socks knitting machine is relatively simple to design, mount and debug, and is relatively high in stability and reliability. The high-reliability socks knitting machine comprises a yarn feeding mechanism for supplying yarns to a knitting mechanism, and a control mechanism for controlling the knitting mechanism, wherein the yarn feeding mechanism comprises a yarn rack, a plurality of supporting plates which are arranged on the yarn rack, are used for storing a bobbin seat and are sequentially distributed from bottom to top, a sensor set arranged above the supporting plate on the uppermost layer, and a yarn guide rod arranged above the sensor group; and the knitting mechanism is provided with the broken needle detection device.

Description

Technical field [0001] The invention relates to the technical field of socks production equipment, in particular to a high-reliability hosiery machine. Background technique [0002] The hosiery machine is one of the important equipment for the production of socks. The hosiery machine is composed of a yarn feeding mechanism, a knitting mechanism and a control mechanism. The yarn feeding mechanism supplies the knitting mechanism with yarn, and the knitting mechanism is controlled by the control mechanism. Automated production reduces labor costs and improves work efficiency. In the existing hosiery machine, the two factors of needle breakage and yarn breakage will directly affect the quality of the socks. It is inevitable that the needle or yarn of the hosiery will be broken due to man-made or external reasons, resulting in the failure of normal knitting. , Resulting in product leakage, affecting product quality and increasing production costs.

In the existing sock knitting machines, the two factors of sock knitting needle breakage and yarn breakage will directly affect the quality of socks. Due to human or external reasons, it is inevitable that the sock knitting needle or yarn will be broken, resulting in the failure of normal knitting. , resulting in product leakage, affecting product quality and increasing production costs

[0003] At present, in the existing hosiery knitting machines, if the thread break detection sensor is not installed, the mechanism is compact and reasonable, and the floor space is small, but it requires more manpower to manually judge whether a thread break occurs, which will increase labor intensity and increase production. Cost. After installing the disconnection detection sensor, due to the large number of wire barrels, it is necessary to set up multiple disconnection detection sensors. In order not to interfere with each other when designing the wiring distribution, the volume will be too large, the structure will not be compact, and it will take up a large area. The use of area is a problem, so while designing a reasonable wiring distribution, it is necessary to ensure the sensitivity of detection

[0004] At present, most of the detection probes of existing broken needle detection devices extend vertically downward from the upper end of the hosiery machine working area to the upper end of the hosiery needle. When a broken needle occurs, there will be a phenomenon of thread stacking, which will promote the detection The probe moves upwards, so the broken needle is detected, that is, the detection probe needs to move axially to detect it. In order to improve the detection accuracy, the detection probe needs to be inserted into the upper end of the sock needle. In actual production, it is found that the above structure is not only sensitive It is relatively low and occupies a limited working area of ​​the hosiery machine, and it is easy to get entangled with the thread, causing problems such as thread breakage. In addition, during the hosiery knitting process, the height of the sock knitting needle needs to change constantly when knitting the heel, so the detection probe It should be far away from the upper end of the sock-knitting needle to avoid false detection. This is inconsistent with the above-mentioned detection probes that extend vertically downward from the upper end of the hosiery machine working area to the upper end of the sock-knitting needle. In order to balance this contradiction, the existing detection device This contradiction needs to be considered in many processes such as design, installation, and debugging, so that the design, installation, and debugging are more complicated, and the stability and reliability are lower.
