Abstract
Description
Technical Field
[0001] The invention relates to the field of zipper manufacturing, in particular to a detection device for a hook and puller. Background Art
[0002] Hook-code zipper is a special type of zipper. This type of zipper head has an anti-reverse function, so it is widely used. The matching relationship between the zipper and the zipper head in traditional hook-code zippers is mostly detected manually. Manual detection is not only inefficient, but also prone to misjudgment. At present, some slider detection devices have appeared on the market. These detection devices are equipped with a detection table. Each slider needs to be installed, tested, and disassembled on the detection table. There are generally many working steps, resulting in low efficiency.
[0003] For example, 201710750905.4 discloses a detection device for a self-locking slider assembly machine, comprising a turntable fixing seat and a vertical turntable rotatably arranged on the side of the turntable fixing seat, a plurality of slider cores for receiving and fixing the slider are arranged at intervals on the vertical turntable, the rear end of the slider is inserted into and fixed in the slider core, a horse hook detection mechanism is also fixed on the turntable fixing seat, the horse hook detection mechanism comprises a push block, a push block slide, a push block driving mechanism and a proximity sensor, the push block slide is fixed on the turntable fixing seat beside the upper middle part of the vertical turntable, The push block can slide through the push block slide seat, and the end of the push block close to the slider is provided with a U-shaped groove in the longitudinal direction that matches the width of the slider cap. The U-shaped groove slides from the front end of the cap toward the pull rod direction of the pull tab, and the inner side wall of the U-shaped groove is tightly attached to the side wall of the cap. The proximity sensor is arranged on the side of the sliding direction of the push block. The proximity sensor is used to sense the sliding distance of the push block. When the sliding distance of the push block is greater than or equal to the sensing distance set by the proximity sensor, the slider is a qualified product; when the sliding distance of the push block is less than the sensing distance set by the proximity sensor, the slider is a defective product.
[0004] The above-mentioned slider detection device inserts the slider into the slider core, and sets a detection device beside the slider core to detect whether the slider on the slider core is qualified. The whole detection process has many steps, and each slider with detection needs to be installed and disassembled on the slider core, resulting in low detection efficiency and involving many reaching mechanisms, which increases the manufacturing cost.

DETAILED DESCRIPTION
[0033] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.
[0034] like Figure 1As shown in FIG2 , a detection device for a hook code slider comprises a slider feeding track 10, on which a slideway 101 for sliding a slider 60 is provided, a material receiving plate 20, a sensing switch 102, and a driving mechanism for driving the material receiving plate 20 to move forward and backward are provided at the outlet of the slider feeding track 10, the material receiving plate 20 is provided with a material receiving groove 201 toward the outlet of the slider feeding track 10, a sensing sheet 30 is slidably provided below the material receiving plate 20, the sensing sheet 30 comprises a contact end 301 for contacting the hook code 602 of the slider 60 toward the outlet direction of the slider feeding track 10, and a sensing end corresponding to the sensing switch 102, the contact end 301 of the sensing sheet 30 is arranged on the travel path of the material receiving groove 201 of the material receiving plate 20, a reset mechanism for resetting the sensing sheet 30 is provided behind the sensing sheet 30, and the sensing switch 102 is arranged behind the sensing end of the sensing sheet 30. Specifically, the hook-code slider is a special slider, which has an anti-backward function, and its function is mainly realized by the hook code 602. When the slider 60 is on the chain belt, one end of the hook code 602 on the slider 60 will be stuck on the chain tooth, and the slider 60 can slide forward, but cannot slide backward. The hook code 602 needs to be lifted by the pull rod 603 to pull the slider 60 backward. When the slider 60 slides from the slider feeding track 10 into the material receiving groove 201 on the material receiving plate 20, the contact end 301 of the induction sheet 30 provided on the material receiving groove 201 detects whether the hook code 602 in the slider protrudes. The hook code 602 of the qualified slider 60 will touch the contact end 301, so that the induction sheet 30 moves backward, and the induction end will connect to the induction switch 102. The hook code 602 of the unqualified slider 60 will not protrude, the induction sheet 30 cannot touch the hook code 602, and the induction end cannot connect to the induction switch 102. It should be noted that the slider 60 is reversely and upside down installed into the slider feeding track 10 , with the slider chain outlet 601 facing forward and the pull rod 603 of the slider 60 facing downward.
[0035] Furthermore, the width of the sensor sheet 30 is smaller than the width of the slider chain outlet 601. Specifically, when the width of the sensor sheet 30 is smaller than the width of the slider chain outlet 601, the sensor sheet 30 can better detect the hook 602 on the slider 60 when detecting the slider 60.
[0036] Furthermore, the sensing end is a protruding block 302 disposed on one side of the sensing sheet 30, and the sensing switch 102 is disposed behind the protruding block 302 on one side of the sensing sheet 30. Specifically, if the sensing end is disposed behind the sensing sheet 30, the sensing head of the sensing switch 102 is likely to interfere with the material receiving plate 20. By disposing the sensing switch 102 on one side of the sensing sheet 30, the sensing head can be extended as much as possible without conflicting with the material receiving plate 20, making the overall design more reasonable.
[0037] Furthermore, a connecting block 103 is provided at the bottom of the material receiving plate 20, a cavity 104 for accommodating the induction sheet 30 and the reset mechanism is formed in the connecting block 103, and a projection opening 105 for the projection block 302 to extend is formed on one side of the cavity 104, and the projection block 302 can move up and down relative to the projection opening 105. Specifically, a connecting block 103 is provided at the bottom of the material receiving plate 20, the induction sheet 30 and the reset mechanism are arranged in the cavity 104 of the connecting block 103, the projection block 302 of the induction sheet 30 is arranged on the projection opening 105, the material receiving plate 20 is fixed on the connecting block 103, and the induction sheet 30 is clamped between the material receiving plate 20 and the connecting block 103 and can move up and down.
[0038] Furthermore, a slider 106 is provided between the driving mechanism and the material receiving plate 20, and a slide rail 401 is formed at the top of the driving mechanism. One end of the slider 106 extends to the driving mechanism and is connected to the slide rail 401 on the driving mechanism. Specifically, the driving mechanism drives the slider 106 to move so that the material receiving plate 20 on the slider 106 is connected to the slider feeding track 10. Since the distance between the driving mechanism and the slider feeding track 10 is far, deviation is easy to occur, so the slide rail 401 is formed at the top of the driving mechanism and is connected to the connection surface of the slider 106.
[0039] Furthermore, two positioning pieces 107 are provided at the end of the slider feeding track 10, which are symmetrically arranged on both sides of the slideway 101. Specifically, two positioning pieces 107 are provided at the end of the slider feeding track 10, and when the slider 60 slides over the positioning pieces 107, the positioning pieces 107 relative to the two sides of the slider 60 can better guide the slider 60 into the receiving groove 201.
[0040] Furthermore, a material receiving step 108 is formed at the end of the slider feeding track 10 for the material receiving plate 20 to support. Specifically, when the material receiving plate 20 is connected to the slider feeding track 10, the front end of the material receiving plate 20 is placed on the material receiving step 108 of the slider feeding track 10, so that the slider feeding track 10 and the material receiving plate 20 are more stable.
[0041] Furthermore, the reset mechanism is a spring 50. Specifically, one end of the spring 50 abuts against the sensing sheet 30 and the other end abuts against the slider 106. After a pull head 60 is detected, the spring 50 drives the sensing sheet 30 to reset.
[0042] Further, the driving mechanism is a cylinder 40. Specifically, the cylinder 40 controls the forward and backward movement of the receiving plate 20, and when the pull head 60 is detected, the cylinder 40 extends, and when the detection is completed, the cylinder 40 retracts.
[0043] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
