Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fiber filament textile, in particular to a warp stop detection device. Background Art
[0002] During the fiber filament textile process, if a break occurs and is not discovered in time, it will cause the situation of following the head and having fewer heads, resulting in more defects in the woven fiber textile cloth and affecting its overall quality. In order to detect breaks in time, an infrared detector is generally used to detect whether there is a break in the fiber yarn at present; the detection method is to set an infrared detector on one side of the loom, and the infrared detector emits infrared rays horizontally; when a certain yarn breaks and its falling process passes through the infrared rays, the infrared detector immediately sends a break signal to the control system, and the control system controls the loom to stop immediately.
[0003] However, in actual application, because the break position of the yarn is not fixed, sometimes after the break, it cannot pass through the infrared rays during its falling process, so the infrared detector cannot measure the break; in addition, even if the infrared detector has detected a break, it cannot accurately locate the break position, and manual search for the break and then wiring are required. Because there are many warp threads on the loom, the search takes a certain amount of time and is very demanding on the eyesight of workers, so the break positioning and wiring efficiency are low, resulting in an extended downtime and delaying the production progress. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a warp stop detection device, which improves the sensitivity of self-stop for breaks, reduces defects; in addition, it can accurately locate the break position, facilitating manual wiring and improving production efficiency.
[0005] To achieve the above purpose, the utility model provides a warp stop detection device, which includes a frame, and a trigger device and an induction device are installed on the frame corresponding to the warp threads; the trigger device is slidably installed on the frame up and down, and a hook for the warp thread to pass through is arranged thereon. When the trigger device is tightened by the warp thread, it will enter / exit the detection area of the induction device; the induction device is used to detect whether the trigger device enters / leaves its detection area.
[0006] With the above structure, by passing the warp thread through the hook, when the trigger device is tightened by the warp thread, it will enter / exit the detection area of the induction device, and then the induction device detects it to judge whether the warp thread breaks, so that the single warp thread can be quickly detected with high detection accuracy, thus reducing defects. At the same time, it can accurately locate the break position, facilitating manual wiring and improving production efficiency.
[0007] For the convenience of installation and maintenance of the induction device, the triggering device includes a wire guide hook that is slidably mounted up and down on the frame. One end of the wire guide hook located inside the frame is provided with a hook, and the warp thread passes through the hook. One end of the top of the wire guide hook extending out of the frame is fixed with a trigger head, and the induction device is fixed above the trigger head. When the wire guide hook is tightened by the warp thread, the tightening force controls the wire guide hook to slide upward against its gravity and enter the detection area of the induction device.
[0008] To improve the sensitivity of the device, a return spring is clamped between the trigger head and the frame.
[0009] To effectively guide the hook and prevent it from swaying left and right, which may affect the operation of its adjacent warp threads, a guide rod is vertically installed at the bottom of the hook, and the guide rod is slidably mounted up and down at the bottom of the frame.
[0010] To protect the induction device and ensure the moving distance of the hook, a limit head is fixed at one end of the bottom of the guide rod extending out of the bottom of the frame.
[0011] To provide sufficient installation space for the hook and the induction device and avoid interference, multiple rows of triggering devices are provided, and each row of triggering devices is arranged on the frame with a left-right offset.
[0012] To increase the selection range of the induction device, the induction device is a proximity switch, a photoelectric sensor, or an infrared sensor.
[0013] After adopting the above technical solutions, the beneficial effects of the present utility model are:
[0014] The warp stop detection device of the present utility model solves the technical problems in the prior art that the infrared detector has low measurement accuracy for broken ends and cannot achieve rapid positioning of broken ends. The present utility model detects it through the induction device to determine whether the warp thread has a broken end, so as to quickly detect a single warp thread with high detection accuracy, thereby reducing defects. At the same time, it can accurately locate the position of the broken end, facilitate manual wiring, and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] All orientations mentioned in this specification are based on the orientation when a warp stop detection device of the present invention is working properly, without limiting its orientation during storage and transportation, only representing relative positional relationships and not absolute positional relationships.
[0021] As Figure 1 、 Figure 2 and Figure 3 collectively show, a warp stop detection device includes a frame 1, a triggering device 3 and a sensing device 4 are installed on the frame 1 corresponding to the warp thread 2. The triggering device 3 is slidably installed up and down on the frame 1, and a hook 31 for the warp thread 2 to pass through is provided thereon. When the triggering device 3 is tightened by the warp thread 2, it will enter / exit the detection area of the sensing device 4, and the sensing device 4 is used to detect whether the triggering device 3 enters / leaves its detection area.
[0022] For example: when the sensing device 4 is fixed above the triggering device 3, when the triggering device 3 is tightened by the warp thread 2, the tightening force controls the triggering device 3 to move upward, then it will enter the detection area of the sensing device 4. When the sensing device 4 detects that the triggering device 3 is in its detection area, it proves that the triggering device 3 is tightened by the warp thread 2. When the warp thread breaks, the tightening force of the triggering device 3 disappears, and the triggering device 3 disengages from the detection area of the sensing device 4 under the action of gravity, and at this time it proves that the warp thread is broken.
[0023] When the sensing device is fixed below the triggering device 3, when the triggering device 3 is tightened by the warp thread 2, the tightening force controls the triggering device 3 to move upward, then it disengages from the detection area of the sensing device 4. At this time, the sensing device 4 cannot detect the triggering device 3, proving that there is no break; when the warp thread breaks, the tightening force of the triggering device 3 disappears, and the triggering device 3 enters the detection area of the sensing device 4 under the action of gravity, and at this time it proves that the warp thread is broken.
[0024] In this embodiment, the triggering device 3 includes a wire guiding hook 32 slidably installed up and down on the frame 1. One end of the wire guiding hook 32 located inside the frame 1 is provided with a hook 31, and the warp thread passes through the hook 31; a triggering head 33 is fixed to one end of the top of the wire guiding hook 32 extending out of the frame 1, and the sensing device 4 is fixed above the triggering head 33; when the wire guiding hook 32 is tightened by the warp thread 2, the tightening force controls the wire guiding hook 32 to slide upward against its gravity and enter the detection area of the above-mentioned sensing device 4.
[0025] In order to ensure that after the wire breaks, the wire guide hook 32 can fall faster and more stably out of the detection area of the out-of-position induction device 4, making the device more sensitive, a return spring 34 is clamped between the trigger head 33 and the frame 1.
[0026] In order to ensure that when the hook 31 slides up and down, it is more stable and avoids shaking, a guide rod 35 is vertically installed at the bottom of the hook 31, and the guide rod 35 is slidably installed up and down at the bottom of the frame 1.
[0027] In order to prevent the warp 2 from being overly tightened, causing the trigger head 33 to hit the induction device 4 and cause damage, a limit head 351 is fixed to the end of the guide rod 35 that extends out of the bottom of the frame 1.
[0028] For reasonable layout and to reduce the width of the device, multiple rows of trigger devices 3 are provided. In this embodiment, two rows are provided, and in practical applications, three rows or other quantities can also be set; each row of trigger devices 3 is arranged on the frame 1 with left-right dislocation.
[0029] The induction device 4 is fixed to the top of the frame 1 through a bracket 11 and is positioned opposite the trigger head 33. The induction device 4 is a proximity switch, a photoelectric sensor, or an infrared sensor.
[0030] A warp stop detection device of the present utility model solves the technical problems in the prior art that the infrared detector has low measurement accuracy for broken ends and cannot achieve rapid positioning of broken ends. The present utility model detects it through an induction device to determine whether the warp has a broken end, so that a single warp can be detected quickly with high detection accuracy, thereby reducing defects, and at the same time, the position of the broken end can be accurately located, facilitating manual wiring and improving production efficiency.
[0031] Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the substantial scope of the present utility model should also fall within the protection scope of the present utility model.
