Description

Technical Field

[0001] The utility model belongs to the technical field of slider production, and particularly relates to a slider conveying device of a slider assembling machine. Background Art

[0002] The elephant nose type zipper head is a kind of slider, which includes a slider body and a pull tab arranged on the slider body. An ear similar to an elephant nose is formed on the slider body, and the pull tab is hung on the ear. Its installation method is generally to arrange the pull tab in the installation gap formed by the ear of the elephant nose, and through the riveting method, the ear deforms to close the installation gap to prevent the automatic slipping of the pull tab.

[0003] In order to realize the automatic assembly of this kind of slider, automatic assembling machines have been developed on the market. Such automatic assembling machines include a turntable, and a slider receiving seat is arranged on the turntable. A slider body conveying device, a pull tab conveying device and a riveting device are arranged on the rotation path of the turntable. The slider body is sent into the slider receiving seat through the slider body conveying device. The turntable rotates to the position of the pull tab conveying device, and the pull tab is sent into the installation gap of the ear through the pull tab conveying device. Then the turntable rotates to the position of the riveting device, and the hook is riveted through the riveting device to complete the assembly of the slider.

[0004] With the change of living standards, in order to make the pull tab more flexible when pulled, one type of zipper head is to first set a hook on the ear of the elephant nose. One end of the hook has a clamping part, and then the pull tab is arranged on the clamping part of the hook. Through the riveting method, the hook deforms to close the clamping part to prevent the automatic slipping of the pull tab.

[0005] Although the above-mentioned assembling machine has the advantages of simple structure and convenient processing, due to reasons such as the vibration of the machine table, the hook will have a slight displacement during the conveying process. When the slider body conveying device conveys the slider with a hook, it is difficult to ensure the stable conveying of the hook. And the slider receiving seat generally includes a seat body, and a receiving groove for accommodating the slider body is arranged on the seat body. Due to reasons such as the vibration of the machine table, the slider body will have a slight displacement in the receiving groove, resulting in the offset of the position of the clamping part of the hook, making it difficult to install the pull tab on the clamping part of the hook during subsequent assembly, affecting the assembly of this kind of slider.

[0006] In view of this, the applicant has conducted in-depth research on the above problems, and thus this case has been produced. Content of the Utility Model

[0051] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0052] As Figures 1 to 5As shown, a pull head conveying device of a pull head assembling machine includes a turntable 10, a pull head conveying mechanism 1 arranged on one side of the turntable 10, and pull head receiving seats 2 annularly and spacedly arranged on the turntable 10. The pull head conveying mechanism 1 is used to convey the pull head 20 to the pull head receiving seat 2, and then the turntable 10 rotates to drive the pull head receiving seat 2 to rotate to the next working station for subsequent work. It should be noted that in this embodiment, the pull head 20 has an elephant trunk 201, and a hook 202 is arranged on the 201. The hook 202 has a clamping portion 204 for arranging a pull tab 203; the pull head conveying mechanism 1 includes a pull head vibrating hopper 11, a pull head guiding track 3 arranged at the discharge port of the pull head vibrating hopper 11, a material distributing mechanism 4 arranged on the pull head guiding track 3, and a pushing mechanism 5 arranged at the bottom of the pull head guiding track 3. Specifically, the middle of the pull head guiding track 3 has a pull head accommodating channel 31, and the top of the pull head accommodating channel 31 has an opening 32 for the elephant trunk 201 and the clamping portion 204 to extend out. The pull head guiding track 3 is inclinedly arranged, and one end of the bottom of the pull head guiding track 3 is the discharge end. The opening 32 extends from the other end of the pull head guiding track 3 to the discharge end. The turntable 10 and the pull head vibrating hopper 11 in the present invention can adopt the existing conventional structures in the art, and will not be elaborated in detail in this embodiment; with such an arrangement, when the pull head guiding track 3 conveys the pull head 20, the pull head 20 and the clamping portion 204 can always be clamped in the opening 32, ensuring the stable conveyance of the pull head 20.

[0053] As Figure 1 , Figure 2 and Figure 5As shown in the figure, the slider receiving seat 2 includes a base 21 provided on the turntable 10 and an upper seat 22 provided above the base 21. A plurality of support columns 23 are connected between the upper seat 22 and the base 21. The number of the support columns 23 can be set according to actual needs and is not limited in this embodiment. Preferably, in this embodiment, each support column 23 is located on both sides of the upper seat 22, and each support column 23 is threadedly connected to the upper seat 22. The support column 23 extends from the top of the upper seat 22 to the bottom of the upper seat 22 and abuts against the top of the base 21. The distance between the base 21 and the upper seat 22 can be adjusted by tightening or loosening the support column 23 so as to adapt to sliders 20 of different specifications; a sink 221 is recessed in the middle of the side of the upper seat 22 away from the center of the turntable 10. A transverse groove 24 is formed between the upper seat 22 and the base 21. The sink 221 is communicated with the transverse groove 24 to form a receiving groove 25 for placing the slider. The transverse groove 24 is used to receive the body of the slider 20, and the sink 221 is used to receive the elephant nose 201. The discharge end of the slider guiding track 3 corresponds to the receiving groove 25 in the slider receiving seat 2. The pushing mechanism 5 is used to push the slider at the discharge end of the slider guiding track 3 into the receiving groove 25; further, a horizontally arranged connecting seat 26 can be provided between the discharge end of the slider guiding track 3 and the receiving groove 25 (the connecting seat can be horizontally and fixedly arranged at the discharge end of the slider guiding track 3), and a transition channel for the slider 20 to pass through is opened in the connecting seat 26. With this setting, the slider 20 falls from the discharge end of the slider guiding track 3 into the connecting seat 26 in a horizontal state, which is convenient for the pushing mechanism 5 to smoothly push the slider 20 into the receiving groove 25; further, a abutting seat 27 for abutting against the slider 20 is further provided on the side of the receiving groove 25 away from the pushing mechanism 5. With this setting, when the pushing mechanism 5 pushes the slider 20 into the receiving groove 25, the position of the slider 20 can be restricted by the abutting seat 27, so that the slider 20 is located in the receiving groove 25, and most of the hook 202 is located outside the receiving groove 25.

[0054] The pushing mechanism 5 of the present utility model includes a pushing cylinder 51 and a pushing plate 52 provided at the output end of the pushing cylinder 51. The pushing cylinder 51 is fixedly provided at the bottom of the slider guiding track 3, and the output end of the pushing cylinder 51 is arranged towards the position of the receiving groove 25. Correspondingly, a notch for the pushing plate 52 to extend into is formed at the bottom of the slider guiding track 3. When the slider 20 with the hook 202 falls into the connecting seat 26 at the discharge end of the slider guiding track 3 under the vibration of the slider vibrating mechanism 11, the pushing cylinder 51 extends so that the pushing plate 52 pushes the slider 20 into the receiving groove 25. Correspondingly, the size of the receiving groove 25 can be adjusted in advance according to the size of the slider 20. Preferably, a guiding inclined surface is further provided on the side of the receiving groove 25 facing the pushing mechanism 5 to facilitate the slider 20 to be more smoothly pushed into the receiving groove 25.

[0055] Further, a jacking mechanism 6 for adjusting the distance between the upper seat 22 and the base 21 is also provided at the position of the bottom of the turntable 10 corresponding to the pull head receiving seat 2. The jacking mechanism 6 includes a jacking cylinder 61 fixed to the bottom of the turntable 10 and a jacking rod 62 fixed to the output end of the jacking cylinder 61. The jacking cylinder 61 is vertically arranged, and the jacking rod 62 passes through the turntable 10 and the base 21 in sequence and is fixedly connected to the upper seat 22. Correspondingly, through holes for the jacking rod 62 to pass through are provided on both the turntable 10 and the base 21. With such a setting, the distance between the upper seat 22 and the base 21 can be flexibly adjusted by the jacking cylinder 61. It should be noted that the jacking mechanism 6 in this embodiment is not limited to the above structure, and other conventional mechanisms in the art that can achieve the above functions can also be used.

[0056] Further, as Figure 1 and Figure 2 shown, a hook correction mechanism 7 for correcting the flatness of the hook 202 is also provided at a position on one side of the turntable 10 close to the pull head conveying mechanism 1. The hook correction mechanism 7 includes a vertically arranged telescopic cylinder 71 and a slide rail 72 provided at the top of the telescopic cylinder 71. The telescopic cylinder 71 is fixed to the frame of the pull head assembling machine, the slide rail 72 is horizontally arranged, and two correction sliders 73 that can move towards or away from each other on the slide rail 72 are provided at the top of the slide rail 72. A slider control mechanism (not shown in the figure) for controlling the simultaneous movement of the two correction sliders 73 is also provided at the top of the telescopic cylinder 71. It should be noted that the slider control mechanism can adopt a conventional two-way synchronous control mechanism in the art, and this embodiment does not limit it here. For example, a two-way cylinder with output ends on both sides can be used. During use, the two correction sliders 73 are correspondingly arranged at the two output ends of the two-way cylinder. The hook correction mechanism 7 is arranged below the rotation path of the pull head receiving seat 2. With such a setting, it is avoided that the pull head receiving seat 2 collides with the hook correction mechanism 7 when rotating. When the turntable 10 drives the pull head receiving seat 2 to be located at the hook correction mechanism 7, the telescopic cylinder 71 extends from below, so that the clamping part 204 of the hook 202 on the pull head receiving seat 2 is located between the two correction sliders 73. The slider control mechanism controls the two correction sliders 73 to move towards each other to clamp and correct the clamping part 204 on the hook 202, so that it is located in the middle of the pull head 20, which is convenient for the subsequent pull tab conveying mechanism (not shown in the figure) to convey the pull tab 203 to the clamping part 204 of the hook 202. It should be noted that the above pull tab conveying mechanism can adopt the pull tab conveying mechanism on the existing conventional pull head assembling machine, and the specific structure will not be elaborated here. During use, the pull tab conveying mechanism is arranged on the rotation path of the pull head receiving seat 2, and the discharge end of the pull tab conveying mechanism is aligned with the clamping part 204 of the hook 202 in the receiving groove 25. It is also possible to manually hang the pull tab 203 on the clamping part 204.

[0057] Further, as Figure 3 andFigure 4 As shown, the material dividing mechanism 4 of the utility model includes two needle blocking mechanisms 43 that can clamp the slider 20 in the slider accommodating channel 31 when descending, and a pin ejector mechanism 44 that drives and controls the up and down movement of the needle blocking mechanism 43. The two needle blocking mechanisms 43 are arranged continuously along the slider accommodating channel 31, and can clamp two sliders 20 adjacent to each other in front and behind. The pin ejector mechanism 44 can sequentially lift up the two needle blocking mechanisms 43 so that only one slider 20 can slide to the discharge end of the slider guide track 3.

[0058] Specifically, the needle blocking mechanism 43 includes a needle blocking movable block 431, a needle blocking fixed block 432 and a blocking needle 433, which are controlled by the ejector mechanism 44. The blocking needle 433 is fixedly mounted on the needle blocking movable block 431 through the needle blocking fixed block 432; the blocking needle 433 faces the slider accommodating channel 31 and extends into the slider accommodating channel 31 to clamp the slider 20. The ejector mechanism 44 can push the needle blocking movable block 431 to rise, thereby allowing the blocking needle 433 to leave the slider 20 and allow the slider 20 to slide down.

[0059] Specifically, the ejector mechanism 44 includes an ejector movable rod 441, a movable block box 442, and an ejector driving cylinder 445 for driving the ejector movable rod 441 to move, wherein the movable block box 442 is provided with two mutually parallel needle stopper movable grooves 443 and an ejector movable groove 444, the ejector movable groove 444 is interconnected with the two needle stopper movable grooves 443, and the needle stopper movable groove 443 and the ejector movable groove 444 are arranged perpendicular to each other; the needle stopper movable block 431 can be slidably embedded in the needle stopper movable groove 443 up and down, and the ejector movable rod 441 can be slidably embedded in the ejector movable groove 444 forward and backward. The front part of the ejector movable rod 441 has a convex part 4411 and the middle part has a concave part 4412. When the convex part 4411 contacts the needle blocking movable block 431, the needle blocking movable block 431 can be lifted up to make the needle blocking 433 leave the slider 20. When the concave part 4412 contacts the needle blocking movable block 431, the needle blocking 433 on the needle blocking movable block 431 can be lowered to clamp the slider 20 in the slider accommodating channel 31. The concave part 4412 should be designed to be larger than the distance between the two needle blocking movable blocks 431, so that at most only one needle blocking movable block 431 can be lifted up by the ejector movable rod 441 at the same time. The movable block box 442 is installed on the side of the slider guide track 3, and the ejector drive cylinder 445 is locked and connected to the rear side of the movable block box 442, and is transmission-connected to the ejector movable rod 441 through an ejector cylinder fixing block 446. The design of the needle blocking mechanism 43 and the ejector mechanism 44 enables the slider 20 to be transported individually.

[0060] The pull head conveying device of the present utility model, the pull head guiding track 3 is provided with a pull head accommodating channel 31, the top of the pull head accommodating channel 31 has an opening 32 for the elephant nose 201 and the hook 202 to protrude, the pull head 20 and the clamping portion 204 can always be clamped in the opening 32, so that the pull head 20 with the hook 202 can be stably conveyed to the discharge end of the pull head guiding track 3, and the push rod mechanism 5 is used to push the pull head 20 at the discharge end into the accommodating groove 25. After the pull head 20 is located in the accommodating groove 25, the clamping portion 204 of the hook 202 is located outside the pull head receiving seat 2, which is convenient for subsequent conveying of the pull tab 203 onto the clamping portion 204.

[0061] Furthermore, a material distributing mechanism 4 is provided to enable single-piece conveying of the pull heads 20 and avoid material jamming.

[0062] Furthermore, a hook correction mechanism 7 is provided to correct the position of the clamping portion 204 on the hook 202, which can effectively avoid the situation of hook 202 deviation and facilitate the subsequent pull tab conveying mechanism to convey the pull tab 203 onto the clamping portion 204 of the hook 202.

[0063] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
