Description

Technical Field

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

[0002] The limit code is the limit at the lower end of the chain belt, which can reduce the chance of misalignment during use. The existing equipment, the upper limit code equipment has a low degree of automation and low production efficiency. Summary of the invention

[0003] In view of the above problems, the present invention provides a zipper upper limit code device, which has the advantages of automatically providing an upper limit code for a chain and improving production efficiency.

[0004] The object of the present invention is achieved in that:

[0005] A zipper upper limit code device comprises a chain belt platform, a chain belt conveying channel is arranged on the chain belt platform, a first chain tooth sensing mechanism is arranged in front of the chain belt platform, a code feeding platform and a code feeding platform driving cylinder for driving the code feeding platform to move forward and backward are arranged in front of the chain belt platform, a second chain tooth sensing mechanism is arranged in the middle of the code feeding platform, two inclined auxiliary surfaces are formed at the front end of the code feeding platform, and the two inclined auxiliary surfaces are arranged at intervals to form a code feeding gap, a downwardly inclined chain outlet channel is arranged at the front lower part of the code feeding platform, and a chain belt traction device is arranged in front of the chain outlet channel;

[0006] A limit code feeding device is also provided in front of the code feeding platform, including a code feeding clamp arranged corresponding to the code feeding gap, which drives the code feeding clamp to perform a clamping action, and a code feeding clamp front and rear cylinders which drive the code feeding clamp to move forward and backward. Limit code feeding channels are provided on both sides of the code feeding clamp, and a feeding device is provided on the limit code feeding channel to sequentially convey the limit codes to the code feeding clamp;

[0007] A limit code pressing device is provided between the code entry platform and the chain exit channel.

[0008] Through the above settings: the chain belt traction device drives the chain belt forward, when the first chain tooth sensing mechanism senses the chain tooth position, the code feeding platform is controlled to move forward to the set position, and then the chain belt continues to move forward, when the second chain tooth sensing mechanism on the code feeding platform senses the front end of the chain tooth, it proves that the chain belt moves to the code feeding position, and then the code feeding clamp is controlled to move backward close to the code feeding platform, the limit code on the code feeding clamp enters the chain belt from the knife edge in front of the chain tooth, and then the code feeding platform retreats, and the limit code pressing device presses the limit code and the chain belt, so as to automatically give the chain belt an upper limit code, thereby improving production efficiency;

[0009] By setting the inclined auxiliary surface and the downward slanted chain outlet channel, the chain belt moves downwardly in the working section of the code feeding, while the code feeding clamp moves horizontally. This makes it easier for the code feeding clamp to feed the limit code through the notch on the chain belt, making the success rate of the upper limit code higher.

[0010] The present invention is further configured as follows: the second sprocket sensing mechanism comprises 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 encoding platform.

[0011] The present invention is further configured as follows: a metal sensing point is also provided on the side of the inclined auxiliary surface for detecting the chain teeth, 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 clamp enters the chain belt from the blade in front of the chain tooth, the chain belt traction device pulls the chain belt to continue to move forward a short distance. When the metal sensing point detects the chain tooth, 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 tooth, so that the limiting effect and anti-misalignment effect are better.

[0013] The present invention is further configured as follows: a code feeding clamp guide seat is arranged at the front lower part of the inclined auxiliary surface, and a code feeding clamp guide groove is formed on the guide seat.

[0014] The setting of the guide groove of the code feeding clamp plays a guiding role when the code feeding clamp approaches the chain belt, thereby providing stability and success rate of code feeding.

[0015] The present invention is further configured as follows: the limit code pressing device includes a punching platform, a punching machine, and left and right driving mechanisms.

[0016] In order to avoid interference with the work in the coding 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 is in place, the coding table is reset, and the stamping platform and the stamping machine move closer to the chain belt and press the limit code and the chain belt.

[0017] The present invention is further configured to include a chain belt table cylinder that drives the chain belt table to move up and down.

[0018] In order to save space, the chain belt table is initially set above the coding table. When the first chain tooth sensing mechanism senses the chain tooth and controls the coding table to move forward, the chain belt table cylinder drives the chain belt table down to a level state with the coding table.

[0019] The present invention is further configured as follows: 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 provided at the front end of the swinging member, the sensing member extends downward to the chain belt travel path, and a proximity switch is provided at the rear end of the swinging member for sensing the upper end of the swinging member.

[0020] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects: the chain belt traction device drives the chain belt forward, and when the first chain tooth sensing mechanism senses the chain tooth position, the coding platform is controlled to move forward to the set position, and then the chain belt continues to move forward, and when the second chain tooth sensing mechanism on the coding platform senses the front end of the chain tooth, it proves that the chain belt moves to the coding position, and then the coding clamp is controlled to move backward close to the coding platform, and the limit code on the coding clamp enters the chain belt from the blade in front of the chain tooth, and then the coding platform retreats, and the limit code pressing device presses the limit code and the chain belt, thereby automatically providing the upper limit code to the chain belt and improving production efficiency.

DETAILED DESCRIPTION

[0028] 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.

[0029] A zipper upper limit code device comprises a chain belt platform 1, a chain belt conveying channel 2 is provided on the chain belt platform 1, a first chain tooth sensing mechanism is provided in front of the chain belt platform 1, a code feeding platform 3 and a code feeding platform driving cylinder 4 for driving the code feeding platform to move forward and backward are provided in front of the chain belt platform 1, a second chain tooth sensing mechanism is provided in the middle of the code feeding platform 3, two inclined auxiliary surfaces 5 are formed at the front end of the code feeding platform 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 at the front lower part of the code feeding platform 3, and a chain belt traction device 8 is provided in front of the chain outlet channel 7;

[0030] A limit code feeding device is also provided in front of the code feeding platform 3, including a code feeding clamp 9 arranged corresponding to the code feeding gap 6, which drives the code feeding clamp to perform a clamping action, and a code feeding clamp front and rear cylinder 11 that drives the code feeding clamp to move forward and backward. A limit code feeding channel 12 is provided on both sides of the code feeding clamp 9, and a feeding device 13 is provided on the limit code feeding channel 12 for feeding the limit code to the code feeding clamp in sequence (the feeding device is a prior art and will not be described in detail here);

[0031] A limit code pressing device is provided between the code entry platform 3 and the chain exit channel 7.

[0032] By setting the inclined auxiliary surface 5 and the downwardly inclined chain outlet channel 7, in the working interval of code feeding, the chain belt moves downwardly, while the code feeding clamp 9 moves horizontally, which makes it more convenient for the code feeding clamp 9 to feed the limit code from the notch on the chain belt, so that the success rate of the upper limit code is higher.

[0033] The second sprocket sensing mechanism comprises a sensing hook 14 and a sensing hook driving device (not shown), and a swinging groove for the sensing hook to swing is formed at the lower middle part of the encoding platform 3 .

[0034] The side of the inclined auxiliary surface 5 is also provided with a metal sensing point 16 for detecting the chain teeth, 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 belt from the knife edge in front of the chain teeth, the chain belt traction device tractions the chain belt to continue to move forward a short distance, and when the metal sensing point 16 detects the chain teeth, it is judged that the movement is in place, and then the code feeding station 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, so that the limit effect and the anti-misalignment effect are better.

[0035] A code feeding clamp guide seat 17 is provided at the front lower part of the inclined auxiliary surface 5, and a code feeding clamp guide groove 18 is formed on the guide seat 17. The code feeding clamp guide groove 18 is provided to guide the code feeding clamp when it approaches the chain belt, thereby providing stability and success rate of code feeding.

[0036] The limit code pressing device includes a punching platform 19, a punching machine 20, and left and right driving mechanisms. In order not to interfere with the work of the code feeding 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 is in place, the code feeding platform is reset, and the punching platform and the punching machine approach the chain belt and press the limit code and the chain belt.

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

[0038] The first chain tooth sensing mechanism includes a mounting seat 22, in which an "L"-shaped swinging member 23 is hinged. A sensing member 24 is provided at the front end of the swinging member 23, and the sensing member 24 extends downward to the chain belt path. 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 forward. When the front end of the sprocket moves under the first sprocket sensing mechanism and drives the sensing member 24 to swing, the proximity switch 25 senses and controls the code feeding platform 3 to move forward to the set position, and then the chain belt continues to move forward. When the sensing hook 14 on the code feeding platform 3 senses the front end of the sprocket, it proves that the chain belt moves to the coding position. The gap is set behind the coding clamp 9, and then the coding clamp 9 is controlled to move backward close to the gap. Since this section of the coding is tilted downward, the limit code on the coding clamp 9 enters the chain belt from the gap in front of the sprocket, and then the chain belt continues to move forward. When the metal sensing point 16 detects the sprocket, it is judged that the movement is in place. At this time, the front end of the sprocket is very close to the limit code, and there is a good limiting effect. Then the coding platform is reset, and the stamping platform 19 and the stamping machine 20 approach the chain belt, and the limit code and the chain belt are pressed tightly to complete the workflow of the upper limit code.

[0040] The invention has the characteristics of automatically providing an upper limit code for the chain belt and improving production efficiency.

[0041] 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.
