Description

Technical Field

[0001] The present invention belongs to the technical field of button processing, and specifically relates to a feeding device for processing buttons. Background Art

[0002] Buttons are small accessories used for connection or decoration on products such as clothing and luggage, and are fixed by means of holes, stitches or magnetic attraction. During the production and processing of buttons, it is necessary to arrange and feed the buttons in an orderly manner to ensure the smooth progress of the production and processing process.

[0003] The patent with the publication number CN206915259U discloses an automatic button sorting device, belonging to the technical field of automatic material sorting. The patent includes a bracket, a conveyor belt, a front baffle, side baffles, an intermediate baffle, a rear baffle, a baffle fixing beam, a height limiting plate, a feeding slope, a feeding hopper and a material limiting plate. The material limiting plate can be driven to move up and down by a driving device such as a motor or a cylinder, the rear baffle can be driven to insert and withdraw from the side of the side baffle by a driving device such as a motor or a cylinder, the distance between the side baffle and the intermediate baffle is slightly larger than the diameter of the button, the feeding ends of the side baffle and the intermediate baffle are provided with arc-shaped chamfers, the distance between the front baffle and the rear baffle is slightly larger than the diameter of the button, and the gap between the height limiting plate and the conveyor belt is slightly larger than the thickness of the button, and the cross section is arc-shaped. This device can realize the multi-row and multi-column sorting of discrete materials such as buttons, with high working efficiency and simple and reliable structure.

[0004] However, the above technical solution still has the following deficiencies in actual application:

[0005] When feeding buttons, the conveyor belt is used to drive the buttons to move. And, the stacked buttons are blocked by the height limiting plate, so that the buttons pass through in a single layer and enter the track composed of the side baffle and the intermediate baffle, and move until they are blocked by the front baffle. The buttons behind are also blocked by the buttons in front, so that the scattered buttons are arranged in a row, so as to facilitate subsequent processing. However, in some cases, the buttons to be conveyed have two sides, an arc surface and a flat surface. When the arc surface of the button contacts the conveyor belt, the contact area between the button and the conveyor belt is smaller than the contact area between the flat surface and the conveyor belt. Therefore, when the button moves with the conveyor belt, it is easy to slip and shake due to inertia. And when the button behind approaches the button in front, the two will collide, and the button behind is easy to slip onto the button in front, resulting in the overlap of the two, thus affecting the sorting effect of the buttons and being unfavorable for the subsequent production and processing.

[0023] 1. For a feeding device for processing buttons according to the present invention, by using the button sorting assembly and the sorting anti-overlap assembly, the scattered buttons can be arranged in an orderly state in the sorting track, which is convenient for subsequent processing. Moreover, during the entire sorting process, the buttons in the sorting track do not contact each other, thereby avoiding the situation that during the sorting process, when the arc surface of the button contacts the conveyor belt and the button at the rear collides with the button at the front, the button at the rear slides onto the button at the front, resulting in the overlap of the two and affecting the button sorting effect, ensuring the progress of subsequent production and processing. And when the buttons are sorted in the sorting track, the distance between adjacent buttons in the sorting track can be changed, and thus different processing procedures can be adapted, which is beneficial to improving the processing efficiency.

[0024] 2. For a feeding device for processing buttons according to the present invention, by using the button flipping group, the buttons in the sorting track can have the same orientation to meet different subsequent processing requirements.

[0025] 3. The feeding device for processing buttons according to the present invention utilizes a pushing component to enable the pushing plate to reciprocally slide on the sorting plate when the buttons move along the sorting plate, thereby pushing the buttons and promoting their movement into the sorting track. This effectively avoids the situation where some buttons get stuck at the sorting plate due to the large frictional force between the buttons and the surface of the sorting plate and cannot move into the sorting track.

[0045] A sorting anti-overlap component is also arranged on the frame 1;

[0046] The sorting anti-overlap component includes a limit rod 12 fixedly connected to one side of the frame body 4, and a plurality of groove blocks 15 sleeved on the limit rod 12. The rightmost groove block 15 is fixedly connected to the end of the limit rod 12, and the remaining groove blocks 15 are slidably connected to the limit rod 12.

[0047] In this embodiment, as Figures 1-7 , Figures 9-11 , Figure 13 , Figure 14As shown, at both ends of the upper side of the frame body 4, a first bidirectional threaded rod 9 is rotatably arranged. Both sides of the first bidirectional threaded rod 9 are threadedly connected to one end of the sorting plate 6. One side of the frame body 4 is fixedly connected with a first motor 8, and the output end of the first motor 8 is fixedly connected to one end of the first bidirectional threaded rod 9.

[0048] On one side of the upper end of the frame body 4, a first cylinder 5 is fixedly connected. The piston end of the first cylinder 5 is fixedly connected to one side of the upper end of the limiting plate 11.

[0049] At one side of the leftmost and rightmost slot blocks 15, a first transmission rod 19 is rotatably arranged. At one side of the remaining slot blocks 15, a second transmission rod 20 is rotatably arranged. One end of the first transmission rod 19 is rotatably connected to one end of the second transmission rod 20, and the ends of adjacent second transmission rods 20 are rotatably connected.

[0050] At one end of the limiting rod 12, a first threaded rod 14 is rotatably arranged. The first threaded rod 14 is threadedly connected to one end of the leftmost slot block 15. One end of the limiting rod 12 is fixedly connected with a second motor 21, and the output end of the second motor 21 is fixedly connected to one end of the first threaded rod 14.

[0051] One end of the connecting plate 16 is fixedly connected with a first spring 24, and the lower end of the first spring 24 is fixedly connected to one side of the slot block 15. One side of the second stop block 18 is fixedly connected with a second spring 29, and the end of the second spring 29 away from the second stop block 18 is fixedly connected to the inner cavity wall of the first stop block 17.

[0052] One side of the connecting plate 16 is fixedly connected with an inclined plate 36. One side of the frame 1 is slidably connected with a push rod 3. One end of the push rod 3 is threadedly connected with a second threaded rod 23. Both ends of the second threaded rod 23 are rotatably arranged on the frame 1. One side of the frame 1 is fixedly connected with a third motor 22, and the output end of the third motor 22 is fixedly connected to one end of the second threaded rod 23. When the push rod 3 moves horizontally, it can contact the inclined plate 36.

[0053] Specifically, in the prior art, when feeding buttons, a conveyor belt 2 is used to drive the buttons to move. And, through a height limiting plate, the stacked buttons are blocked so that the buttons pass through in a single layer and enter the track composed of side baffles and middle baffles, and move until they are blocked by the front baffle. The buttons behind are also blocked by the buttons in front, so that the scattered buttons are in an arranged state for subsequent processing. However, in some cases, the buttons to be conveyed have two sides, an arc surface and a flat surface. When its arc surface contacts the conveyor belt 2, the contact area between the button and the conveyor belt 2 is smaller than the contact area between the flat surface and the conveyor belt 2. Therefore, when the button moves with the conveyor belt 2, it is easy to slip and shake due to inertia. And when the button behind approaches the button in front, the two will collide, and then the button behind is easy to slip onto the button in front, resulting in the overlap of the two, thus affecting the sorting effect of the buttons and being unfavorable for the subsequent production and processing.

[0054] Therefore, to solve the above problems, when this embodiment is in use, first, according to the diameter and thickness of the buttons to be conveyed, the first motor 8 and the first cylinder 5 are started respectively. When the first motor 8 drives the first bidirectional threaded rod 9 to rotate, the distance between the two sorting plates 6 can be adjusted, so that only one button can pass through the minimum distance between the sorting plates 6 at a time, and the buttons cannot pass side by side. Moreover, the second stopper 18 will slide inside the first stopper 17 due to the movement of the sorting plate 6, and under the action of the second spring 29, the second stopper 18 will always be in close contact with the sorting plate 6. When the first cylinder 5 drives the limiting plate 11 to move up and down, the distance between the bottom of the limiting plate 11 and the upper surface of the conveyor belt 2 can be adjusted, so that the buttons can only pass through in a single layer;

[0055] Then, the buttons are placed on the conveyor belt 2, and the conveyor belt 2 is driven to operate, driving the buttons to move. The buttons move along the sorting plate 6 and pass through the opening formed by the cooperation of the limiting plate 11, the conveyor belt 2, and the sorting plate 6, and only one button can pass through the opening at a time. Then the buttons enter the sorting track. Moreover, when a button passes through the opening, the visual detection mechanism 30 will recognize the button, and then the limiting plate 11 descends to seal the opening, so that the subsequent buttons are blocked. The buttons in the sorting track still move. At the same time, the third motor 22 drives the second threaded rod 23 to rotate, so that the push rod 3 moves from right to left, and its end will squeeze the rightmost inclined plate 36, causing the connecting plate 16 to move downward along the chute of the groove block 15 until the first stopper 17 and the second stopper 18 are in contact with the surface of the conveyor belt 2 to block the buttons. Then the limiting plate 11 rises again, and the subsequent buttons can pass through. Moreover, the push rod 3 continues to move, squeezing the subsequent inclined plates 36 to block the buttons again, and then repeating the above operations, the buttons in the sorting track are separated. When a certain number of buttons are sorted, the conveyor belt 2 stops operating, the push rod 3 moves away from the inclined plate 36, and the connecting plate 16 resets under the action of the first spring 24. At this time, the buttons in the sorting track maintain the same distance. Then the conveyor belt 2 continues to operate, and a row of buttons can be conveyed to the designated position for processing. During the entire sorting process, the buttons in the sorting track do not contact each other, thus avoiding the situation that during the sorting process, when the arc surface of the button contacts the conveyor belt 2 and the subsequent button collides with the previous button, the subsequent button slides onto the previous button, resulting in the overlap of the two and affecting the sorting effect of the buttons, ensuring the subsequent production and processing. Moreover, compared with the method of setting another limiting plate 11 at the end of the sorting track to separate the overlapping buttons, the above method will not affect the distance between adjacent buttons that have been sorted;

[0056] Although the above method can prevent the buttons from overlapping due to mutual collision, the spacing between adjacent buttons is the same. Usually, different processing procedures have specific requirements for the spacing between adjacent buttons. If the spacing between adjacent buttons is a fixed value, it is not conducive to adapting to different processing procedures and will affect the processing efficiency. Therefore, to solve this problem, after the buttons are sorted in the sorting track, the motor two 21 can drive the first threaded rod 14 to rotate, so as to drive the leftmost slot block 15 to slide on the limiting rod 12. At the same time, under the cooperation of the first transmission rod 19 and the second transmission rod 20, the other slot blocks 15 also slide on the limiting rod 12, and the spacing between adjacent slot blocks 15 changes equally, adjusting the spacing between adjacent second stoppers 18. Then, the conveyor belt 2 is used to drive the buttons to move, so that the buttons in the sorting track contact the first stopper 17 on its right again, and the spacing between adjacent buttons in the sorting track is changed, thus achieving the purpose of controlling the spacing between adjacent buttons in the same row, and further being able to adapt to different processing requirements and being beneficial to improving the processing efficiency.

[0057] In this embodiment, as Figure 7 and Figure 8 shown, a button flipping assembly is further provided on the frame 4;

[0058] The button flipping assembly includes a second cylinder 13 fixedly connected to the middle of the upper end of the frame 4. The piston end of the second cylinder 13 is fixedly connected with a lifting plate 31. Both ends of the lower side of the lifting plate 31 are fixedly connected with second sliding rods 34. Both sides of the second sliding rods 34 are slidably connected with threaded blocks 35. One side of the lower end of the threaded block 35 is rotatably provided with a clamping block 28.

[0059] Both ends of the lifting plate 31 are rotatably provided with a second bidirectional threaded rod 33. Both sides of the second bidirectional threaded rod 33 are threadedly connected with the threaded blocks 35. One end of the lifting plate 31 is fixedly connected with a fifth motor 32. The output end of the fifth motor 32 is fixedly connected with one end of the second bidirectional threaded rod 33. One side of the lower end of the threaded block 35 is fixedly connected with a sixth motor 37. The output end of the sixth motor 37 is fixedly connected with one side of the clamping block 28.

[0060] Specifically, since the vision detection mechanism can distinguish the orientation of the buttons, when the buttons are detected by the vision detection mechanism, the conveyor belt stops, and the second cylinder drives the lifting plate to descend, so that the buttons are located between the two clamping blocks. Then, the fifth motor drives the second bidirectional threaded rod to rotate to drive the two threaded blocks to approach each other, and the buttons are clamped by the clamping blocks. Then, the buttons are driven to rise, and the fifth motor is used to drive the buttons to rotate, so that the buttons can be flipped, so that the buttons in the sorting track have the same orientation to adapt to subsequent different processing requirements.

[0061] In this embodiment, as Figure 11 and Figure 12 shown, a pushing component is further provided on the sorting plate 6;

[0062] The pushing component includes a push plate 7 slidably connected to one side of the sorting plate 6. One side of the upper end of the push plate 7 is rotatably provided with a second connecting rod 27. One end of the second connecting rod 27 is rotatably provided with a first connecting rod 26. One end of the first connecting rod 26 is rotatably provided on the sorting plate 6. One side of the upper end of the sorting plate 6 is fixedly connected with a fourth motor 25. The output end of the fourth motor 25 is fixedly connected to one end of the first connecting rod 26.

[0063] Specifically, in the above embodiment, although the scattered buttons can be gathered and arranged through the sorting plate 6, however, when the frictional force between the buttons and the surface of the sorting plate 6 is large, some buttons may get stuck at the sorting plate 6 and cannot move into the sorting track.

[0064] Therefore, to solve the above problems, when in use in this embodiment, when the buttons move along the sorting plate 6, the fourth motor 25 can drive the first connecting rod 26 to rotate, and with the cooperation of the second connecting rod 27, the push plate 7 can reciprocally slide on the sorting plate 6, so as to push the buttons, thereby promoting the buttons to move into the sorting track, effectively avoiding the situation that some buttons get stuck at the sorting plate 6 and cannot move into the sorting track due to the large frictional force between the buttons and the surface of the sorting plate 6.

[0065] Working principle: First, according to the diameter and thickness of the buttons to be conveyed, motor 1 (8) and cylinder 1 (5) are started respectively. When motor 1 (8) drives the bidirectional threaded rod 1 (9) to rotate, the distance between the two sorting plates 6 can be adjusted, so that only one button can pass through the minimum distance between the sorting plates 6 at a time, and the buttons cannot pass side by side. Moreover, the second stopper 18 will slide inside the first stopper 17 due to the movement of the sorting plate 6, and under the action of the second spring 29, the second stopper 18 will always keep in close contact with the sorting plate 6. When cylinder 1 (5) drives the limiting plate 11 to move up and down, the distance between the bottom of the limiting plate 11 and the upper surface of the conveyor belt 2 can be adjusted, so that the buttons can only pass through in a single layer. Then, the buttons are placed on the conveyor belt 2, and the conveyor belt 2 is driven to operate, driving the buttons to move. The buttons move along the sorting plate 6 and pass through the opening formed by the cooperation of the limiting plate 11, the conveyor belt 2 and the sorting plate 6, and only one button can pass through the opening at a time. Then the buttons enter the sorting track. Moreover, when a button passes through the opening, the visual detection mechanism 30 will recognize the button, and then the limiting plate 11 will descend to seal the opening, so that the subsequent buttons are blocked. The buttons in the sorting track still move. At the same time, motor 3 (22) drives the threaded rod 2 (23) to rotate, so that the push rod 3 moves from right to left, and its end will squeeze the rightmost inclined plate 36, causing the connecting plate 16 to move downward along the chute of the groove block 15 until the first stopper 17 and the second stopper 18 are in contact with the surface of the conveyor belt 2 to block the buttons. Then the limiting plate 11 rises again, and the subsequent buttons can pass through. Moreover, the push rod 3 continues to move, squeezing the subsequent inclined plates 36 to block the buttons again, and then the above operations are repeated. The buttons in the sorting track are separated. When a certain number of buttons are sorted, the conveyor belt 2 stops operating, the push rod 3 moves away from the inclined plate 36, and the connecting plate 16 resets under the action of the first spring 24. At this time, the buttons in the sorting track maintain the same distance. Then the conveyor belt 2 continues to operate, and a row of buttons can be conveyed to the designated position for processing. During the whole sorting process, the buttons in the sorting track do not contact each other, thus avoiding the situation that during the sorting process, when the arc surface of the button contacts the conveyor belt 2 and the rear button collides with the front button, the rear button slides onto the front button, resulting in the overlap of the two, which affects the sorting effect of the buttons, ensuring the subsequent production and processing. Moreover, compared with the method of setting another limiting plate 11 at the end of the sorting track to separate the overlapping buttons, the above method will not affect the distance between adjacent buttons that have been sorted;Although the above method can avoid the superposition of buttons due to mutual collision, the spacing between adjacent buttons is the same. Usually, different processing procedures have specific requirements for the spacing between adjacent buttons. If the spacing between adjacent buttons is a fixed value, it is not conducive to adapting to different processing procedures and affects the processing efficiency. Therefore, to solve this problem, after the buttons are sorted in the sorting track, the motor two 21 can drive the rotation of the first threaded rod 14 to drive the leftmost groove block 15 to slide on the limiting rod 12. At the same time, under the cooperation of the first transmission rod 19 and the second transmission rod 20, the other groove blocks 15 also slide on the limiting rod 12, and the spacing between adjacent groove blocks 15 changes equally, adjusting the spacing between adjacent second stoppers 18. Then, the conveyor belt 2 is used to drive the buttons to move, so that the buttons in the sorting track contact the first stopper 17 on its right again, and the spacing between adjacent buttons in the sorting track is changed, thus achieving the purpose of controlling the spacing between adjacent buttons in the same row, and further being able to adapt to different processing requirements and being beneficial to improving the processing efficiency; Since the visual inspection mechanism can distinguish the orientation of the buttons, when the buttons are detected by the visual inspection mechanism, the conveyor belt stops, the second cylinder drives the lifting plate to descend, so that the buttons are located between the two clamping blocks. Then, the motor five drives the rotation of the second bidirectional threaded rod to drive the two threaded blocks to approach each other, and the buttons are clamped by the clamping blocks. Then, the buttons are driven to rise, and the motor five is used to drive the buttons to rotate, so that the buttons can be flipped, so that the buttons in the sorting track have a unified orientation to adapt to subsequent different processing requirements; When the buttons move along the sorting plate 6, the motor four 25 can drive the rotation of the first connecting rod 26, and under the cooperation of the second connecting rod 27, the pushing plate 7 reciprocates on the sorting plate 6, so that the buttons can be pushed, thereby promoting the movement of the buttons into the sorting track, effectively avoiding the situation that some buttons are stuck at the sorting plate 6 and cannot move into the sorting track due to the large frictional force between the buttons and the surface of the sorting plate 6.;

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
