Description

Technical Field

[0001] The utility model belongs to the field of zipper machine equipment and relates to a device for the upper limit code of a zipper. Technical Background

[0002] The limit code plays a limiting role at the lower end of the chain belt, which can reduce the probability of tooth misalignment during use. In the existing equipment, the automation degree of the equipment for the upper limit code is low and the production efficiency is not high. Summary of the Invention

[0003] According to the above problems, the present invention provides a device for the upper limit code of a zipper, which has the advantages of automatically applying the upper limit code to the chain belt and improving the production efficiency.

[0004] The purpose of the utility model is achieved as follows:

[0005] A device for the upper limit code of a zipper includes a chain belt table, a chain belt conveying channel is arranged on the chain belt table, a first chain tooth induction mechanism is arranged in front of the chain belt table, a code feeding table and a code feeding table driving air cylinder for driving the code feeding table to move back and forth are arranged in front of the chain belt table, a second chain tooth induction mechanism is arranged in the middle of the code feeding table, two inclined auxiliary surfaces are formed at the front end of the code feeding table, and the two inclined auxiliary surfaces are arranged at intervals to form a code feeding gap. An out-chain channel inclined downward is arranged below the front of the code feeding table, and a chain belt traction device is arranged in front of the out-chain channel;

[0006] A limit code feeding device is further arranged in front of the code feeding table, including a code feeding clamp corresponding to the code feeding gap, a clamping air cylinder for driving the code feeding clamp to perform a clamping action, and a front and rear air cylinder for driving the code feeding clamp to move back and forth. Code feeding channels are arranged on both sides of the code feeding clamp, and a feeding device for sequentially feeding limit codes to the code feeding clamp is arranged on the code feeding channels;

[0007] A limit code pressing device is arranged between the code feeding table and the out-chain channel.

[0008] Through the above settings: the chain belt traction device drives the chain belt to move forward. When the first chain tooth induction mechanism senses the position of the chain teeth, the code feeding table is controlled to move forward to a set position, and then the chain belt continues to move forward. When the second chain tooth induction mechanism on the code feeding table senses the front end of the chain teeth, it proves that the chain belt has moved to the code feeding position. Then, the code feeding clamp is controlled to move backward and close to the code feeding table, and the limit code on the code feeding clamp enters the chain belt from the cutting edge in front of the chain teeth. Then, the code feeding table retracts, and the limit code pressing device presses the limit code and the chain belt tightly, realizing automatic application of the upper limit code to the chain belt and improving the production efficiency;

[0009] Through the setting of the inclined auxiliary surface and the downwardly inclined out-chain channel, in the working interval of code feeding, the chain belt moves obliquely downward, while the code feeding clamp moves horizontally. This makes it more convenient for the code feeding clamp to feed the limit code from the notch on the chain belt, and the success rate of applying the upper limit code is higher.

[0010] The present invention is further configured that: the second chain tooth sensing mechanism includes a sensing hook and a sensing hook driving device, and a swinging groove for the sensing hook to swing is formed below the middle of the code feeding table.

[0011] The present invention is further configured that: a metal sensing point for detecting the chain teeth is further provided on the side of the inclined auxiliary surface, and the metal sensing point is arranged in front of the sensing hook.

[0012] Through the design of the metal sensing point, when the limit code on the code feeding clip enters the chain belt from the knife edge in front of the chain teeth, the chain belt traction device traction the chain belt to continue to move forward a short distance. When the metal sensing point detects the chain teeth, it is judged that the movement is in place, and then the code feeding table is controlled to reset, and the limit code pressing device presses the limit code. At this time, the limit code is closer to the chain teeth, so that the limit effect and the anti-misaligned teeth effect are better.

[0013] The present invention is further configured that: a code feeding clip guiding seat is arranged in front of the lower part of the inclined auxiliary surface, and a code feeding clip guiding groove is formed on the guiding seat.

[0014] Through the arrangement of the code feeding clip guiding groove, it plays a guiding role when the code feeding clip approaches the chain belt, thereby providing the stability and success rate of code feeding.

[0015] The present invention is further configured that: the limit code pressing device includes a stamping platform, a stamping machine and a left and right driving mechanism.

[0016] In order not to interfere with the work in the code feeding stage, it is preferably to arrange the limit code pressing device on the side of the working channel. When the limit code enters the chain belt and is in place, after the code feeding table resets, the stamping platform and the stamping machine approach the chain belt and press the limit code and the chain belt tightly.

[0017] The present invention is further configured that: it further includes a chain belt table air cylinder for driving the chain belt table to move up and down.

[0018] In order to save space, the chain belt table is initially arranged above the code feeding table. When the first chain tooth sensing mechanism senses the chain teeth and controls the code feeding table to move forward, the chain belt table air cylinder drives the chain belt table to descend to a horizontal state with the code feeding table.

[0019] The present invention is further configured that: the first chain tooth sensing mechanism includes a mounting seat, an "L"-shaped swinging member is hinged in the mounting seat, a sensing member is arranged at the front end of the swinging member, the sensing member extends downward to the chain belt running path, and a proximity switch is arranged at the rear end of the swinging member for sensing the upper end of the swinging member.

[0020] The prominent and beneficial technical effects of the present invention compared with the prior art are as follows: The chain belt traction device drives the chain belt forward. When the first chain tooth induction mechanism senses the position of the chain teeth, the code input table is controlled to move forward to the set position. Then the chain belt continues to move forward. When the second chain tooth induction mechanism on the code input table senses the front end of the chain teeth, it proves that the chain belt has moved to the code input position. Then the code input clamp is controlled to move backward and approach the code input table. The limit code on the code input clamp enters the chain belt from the cutting edge in front of the chain teeth. Then the code input table retracts, and the limit code pressing device presses the limit code and the chain belt tightly, realizing the automatic limiting code for the chain belt and improving production efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope protected by the present invention.

[0029] A zipper upper limit code device includes a chain tape table 1, a chain tape conveying channel 2 is provided on the chain tape table 1, a first chain tooth sensing mechanism is provided in front of the chain tape table 1, a code feeding table 3 and a code feeding table driving air cylinder 4 for driving the code feeding table to move back and forth are provided in front of the chain tape table 1, a second chain tooth sensing mechanism is provided in the middle of the code feeding table 3, two inclined auxiliary surfaces 5 are formed at the front end of the code feeding table 3, and the two inclined auxiliary surfaces 5 are arranged at intervals to form a code feeding gap 6. A downwardly inclined chain outlet channel 7 is provided below the front of the code feeding table 3, and a chain tape traction device 8 is provided in front of the chain outlet channel 7;

[0030] A limit code feeding device is further provided in front of the code feeding table 3, including a code feeding clamp 9 corresponding to the code feeding gap 6, a clamping air cylinder 10 for driving the code feeding clamp to perform a clamping action, and a front and rear air cylinder 11 for driving the code feeding clamp to move back and forth. Limiting code feeding channels 12 are provided on both sides of the code feeding clamp 9, and a feeding device 13 for sequentially feeding limit codes to the code feeding clamp is provided on the limiting code feeding channel 12 (the feeding device is a prior art and will not be elaborated here);

[0031] A limit code pressing device is provided between the code feeding table 3 and the chain outlet channel 7.

[0032] Through the arrangement of the inclined auxiliary surface 5 and the downwardly inclined chain outlet channel 7, the chain tape moves downwardly inclined during the working interval of code feeding, while the code feeding clamp 9 moves horizontally. This makes it more convenient for the code feeding clamp 9 to feed the limit code into the chain tape from the notch on the chain tape, resulting in a higher success rate of upper limit code.

[0033] The second chain tooth sensing mechanism includes a sensing hook 14 and a sensing hook driving device (not shown), and a swinging groove for the sensing hook to swing is formed below the middle of the code feeding table 3.

[0034] A metal sensing point 16 for detecting chain teeth is further provided on the side of the inclined auxiliary surface 5, and the metal sensing point 16 is arranged in front of the sensing hook 14. Through the design of the metal sensing point 16, when the limit code on the code feeding clamp 9 enters the chain tape from the cutting edge in front of the chain teeth, the chain tape traction device pulls the chain tape to move forward a short distance. When the metal sensing point 16 detects the chain teeth, it is determined that the movement is in place, and then the code feeding table 3 is controlled to reset, and the limit code pressing device presses the limit code. At this time, the limit code is closer to the chain teeth, resulting in better limiting effect and anti-misaligned tooth effect.

[0035] An encoding clip guide base 17 is provided at the front lower part of the inclined auxiliary surface 5, and an encoding clip guide groove 18 is formed on the guide base 17. Through the arrangement of the encoding clip guide groove 18, it plays a guiding role when the encoding clip approaches the chain belt, thereby providing the stability and success rate of encoding.

[0036] The limit code pressing device includes a stamping platform 19, a stamping machine 20 and a left and right driving mechanism. In order not to interfere with the work during the encoding stage, it is preferred to set the limit code pressing device on the side of the working channel. When the limit code enters the chain belt and reaches the position, after the encoding table resets, the stamping platform and the stamping machine approach the chain belt and press the limit code and the chain belt tightly.

[0037] It also includes a chain belt table cylinder (21) for driving the chain belt table 1 to move up and down. In order to save space, the chain belt table is initially set above the encoding table. When the first chain tooth sensing mechanism senses the chain tooth and controls the encoding table to move forward, the chain belt table cylinder drives the chain belt table to descend to a horizontal state with the encoding table.

[0038] The first chain tooth sensing mechanism includes a mounting seat 22, an "L" - shaped swinging member 23 is hinged inside the mounting seat 22, a sensing member 24 is provided at the front end of the swinging member 23, the sensing member 24 extends downward to the chain belt running path, and a proximity switch 25 is provided at the rear end of the swinging member for sensing the upper end of the swinging member.

[0039] Working principle: The chain belt traction device 8 drives the chain belt to move forward. When the front end of the chain tooth reaches below the first chain tooth sensing mechanism and drives the sensing member 24 to swing, after being sensed by the proximity switch 25, it controls the encoding table 3 to move forward to the set position. Then the chain belt continues to move forward. When the sensing hook 14 on the encoding table 3 senses the front end of the chain tooth, it proves that the chain belt has moved to the encoding position. The notch is set behind the encoding clip 9. Then it controls the encoding clip 9 to move backward and approach the notch. Since this section of the encoding is set to be inclined downward, the limit code on the encoding clip 9 enters the chain belt from the notch in front of the chain tooth. Then the chain belt continues to move forward. When the metal sensing point 16 detects the chain tooth, it is judged that the movement is in place. At this time, the front end of the chain tooth is very close to the limit code, having a good limit effect. Then the encoding table resets, the stamping platform 19 and the stamping machine 20 approach the chain belt, and press the limit code and the chain belt tightly to complete the working process of the upper limit code.

[0040] The present invention has the characteristics of automatically feeding the upper limit code to the chain belt and improving production efficiency.

[0041] The above - mentioned embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
