Description

Technical Field

[0001] The present invention belongs to the technical field of feeding devices, and specifically relates to an automated feeding device for the production of the armrest surfaces of outdoor camping folding chairs. Background Art

[0002] An outdoor camping folding chair is a portable seat designed specifically for outdoor activities. The armrest surface refers to the part on both sides of the chair for arm support. During the production process of the armrest surface, an automated feeding device is required to transport the armrest surface to a designated position for processing to replace traditional manual feeding.

[0003] The patent with the publication number CN222389137U discloses an automated feeding device for the production of chair armrest surfaces, which relates to the technical field of feeding devices and includes a base. A bracket is fixedly installed on the surface of the base, and a storage bin is fixedly installed on the surface of the bracket. By setting the structures of the base, bracket, storage bin, inclined table, first motor, first lead screw, first sliding block, push plate, first notch, fixed plate, second notch, second motor, second lead screw, second sliding block, placing plate, and third notch, when the first notch aligns with the bottom end of the inclined table, the parts will fall onto the surface of the first notch. The first lead screw drives the first sliding block and the push plate to push the parts inside the first notch towards the second notch on the surface of the fixed plate. Subsequently, the parts will fall from the second notch into the third notch. Then, the first motor retracts the push plate, and the second part falls into the first notch again. By repeating the above operations, the push plate can push the parts out in sequence, avoiding excessive numbers of parts when sliding from the storage bin and causing equipment chaos.

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

[0005] By adding multiple armrest surface parts to the storage bin and then pushing the parts out in sequence by the push plate, although this method can achieve separated feeding to avoid feeding chaos, generally, in order to ensure the continuity of the processing of multiple parts and improve the processing efficiency, it is necessary to make multiple parts at a unified angle. However, after the parts are pushed out by the push plate, their angles are random, resulting in non-uniform angles of multiple parts, affecting the continuity and efficiency of part processing.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. For the automatic feeding device for the production of the armrest surface of an outdoor camping folding chair according to the present invention, by using the limiting component, multiple scattered parts can be gathered at the same place and neatly arranged, thus realizing the separated feeding of multiple parts, avoiding feeding chaos, and moreover, the angles of each part can be unified, improving the continuity and efficiency of the subsequent processing of the parts.

[0026] 2. For the automatic feeding device for the production of the armrest surface of an outdoor camping folding chair according to the present invention, by using the component for detecting the front and back of the parts and the component for clamping the parts, each part can be placed with the plane facing downwards, which not only avoids the situation of shaking and offset of the parts due to the arc surface facing downwards, but also ensures the unified orientation of each part, further ensuring the continuity and efficiency of the subsequent processing of the parts.

[0027] 3. For the automatic feeding device for the production of the armrest surface of an outdoor camping folding chair according to the present invention, whenever a part is placed on the first conveyor belt, the turning block can be used to clamp the part and change the orientation of the part on the first conveyor belt, so that the parts are arranged in multiple rows, reducing the total length of the arrangement of the same batch of parts on the first conveyor belt. When the same batch of parts move to the designated position, since the same batch of parts are arranged in multiple rows in an orderly manner and the total length is reduced, it is convenient to perform operations such as unified packaging and storage of the parts. Moreover, by using the feeding auxiliary component, during the entire feeding process, the parts are in a limited state, thus avoiding the situation that the parts are offset due to external forces, which in turn affects subsequent operations such as packaging. And since the feeding auxiliary components are arranged on both sides of the first frame, the equipment for operating on the parts can be arranged on both sides of the first frame, and the two groups of feeding auxiliary components limit the parts, which is beneficial to improving work efficiency.

[0028] 4. An automatic feeding device for the production of the armrest surface of an outdoor camping folding chair according to the present invention utilizes an anti-overlapping component. According to the length of the parts, the first anti-overlapping plate slides on the second anti-overlapping plate until the end of the first anti-overlapping plate is above the end of the part blocked by the baffle, driving the first anti-overlapping plate to be almost in contact with the part. At this time, when the subsequent parts squeeze the parts blocked by the baffle, there will be no overlapping situation due to the block of the first anti-overlapping plate, thus avoiding the situation that when the baffle blocks the parts, because the subsequent parts are in a continuous motion state, when the arc surface of the part faces downwards, the part moves above the part blocked by the baffle, resulting in part overlapping and affecting subsequent feeding.

[0052] In this embodiment, as Figures 1 - 9 、 Figure 14 shown, a cylinder three 22 is fixedly connected to one side of the upper end face of the cross beam one 4.

The baffle 47 can pass through the through hole at the end of the feeding plate 5.

[0053] A threaded block 23 is threadedly connected to the upper end of a two-way threaded rod two 24. Both ends of the two-way threaded rod two 24 are rotatably arranged on the cross beam one 4. A motor four 25 is fixedly connected to one side of the upper end of the cross beam one 4. The output end of the motor four 25 is fixedly connected to one end of the two-way threaded rod two 24.

[0054] One end of the adjustment plate 53 is threadedly connected to a threaded rod six 50. One end of the threaded rod six 50 is rotatably arranged on the cross beam three 9. A motor nine 48 is fixedly connected to one side of the upper end of the cross beam three 9. The output end of the motor nine 48 is fixedly connected to one end of the threaded rod six 50.

[0055] One side of the lower end of the cross beam two 8 is threadedly connected to a threaded rod two 12. Both ends of the threaded rod two 12 are rotatably arranged on the bottom plate 2. A motor two 13 is fixedly connected to one side of the upper end face of the bottom plate 2. The output end of the motor two 13 is fixedly connected to one end of the threaded rod two 12.

[0056] One end of the clamping plate 19 is threadedly connected to a two-way threaded rod one 18. Both ends of the two-way threaded rod one 18 are rotatably arranged on the mounting plate 16. A motor three 17 is fixedly connected to one end of the mounting plate 16. The output end of the motor three 17 is fixedly connected to one end of the two-way threaded rod one 18. A motor five 26 is fixedly connected to one side of the inner cavity of the clamping plate 19. The output end of the motor five 26 is fixedly connected to the turning block 20.

[0057] Specifically, when the existing automatic feeding device for armrest surfaces is in use, multiple armrest surface parts are added to the storage bin, and then the parts are sequentially pushed out by the push plate. Although this method can achieve separated feeding to avoid feeding chaos, usually, in order to ensure the continuity of processing of multiple parts and improve processing efficiency, it is necessary to make multiple parts at a unified angle. However, after the parts are pushed out by the push plate, their angles are random, resulting in inconsistent angles of multiple parts, which affects the continuity and efficiency of part processing.

[0058] Therefore, to solve the above problems, in this embodiment, when in use, the same batch of armrest surfaces with the same specifications are used, and usually, the armrest surface parts are strip-shaped; according to the thickness and width of the parts when placed flat, the two-way threaded rod two 24 is rotated by the motor four 25 to adjust the distance between the two threaded blocks 23 and the feeding plate 5 until the minimum distance between the two feeding plates 5 is greater than the width of one part and less than the width of two parts. At the same time, the partition plate 29 is driven to move up and down by the cylinder three 22 to adjust the distance between the bottom of the partition plate 29 and the upper surface of the conveyor belt two 6, and this distance is greater than the thickness of one part when placed flat and less than the thickness of two parts stacked.

[0059] Then the parts are added to the conveyor belt two 6, and the conveyor belt two 6 is driven to operate. Since the armrest moving channel formed by the two feeding plates 5 is from wide to narrow, the parts will converge towards the narrowest part of the feeding plate 5 due to the operation of the conveyor belt two 6. And because the partition plate 29 and the feeding plate 5 cooperate with each other to form a part inlet, and only one part can pass through the inlet at a time, the parts will be arranged at the narrowest distance between the two feeding plates 5, and then the parts are sequentially sent to the conveyor belt one 3. The conveyor belt one 3 drives the parts to move for feeding, thus not only achieving separated feeding of multiple parts to avoid feeding chaos, but also making the angles of each part unified, improving the continuity and efficiency of subsequent part processing.

[0060] Although the above method can make the angle of each part uniform, in some cases, one side of the part is an arc surface, which is to adapt to the natural bending of the arm. When multiple parts are arranged between the feed plates 5, the arc surface may face upward or downward. When the arc surface faces downward, the contact area between the arc surface and the conveyor belt 3 is small, and the parts are prone to shaking and offset, resulting in multiple parts on the conveyor belt 3 being uneven and not uniform in direction, which still affects the continuity of subsequent processing. Therefore, in order to solve the above problem, when the part is between the two feed plates 5, the baffle 47 is used to block the part, and the motor is used to The nine 48 drives the threaded rod six 50 to rotate, so that the adjustment plate 53 moves horizontally, and adjusts the distance between the two pressure sensors 52 so that the distance is equal to the length of a part. Then, the electric push rods 51 on both sides are started at the same time to drive the pressure sensors 52 to descend until the pressure sensors 52 contact the two ends of the part. When the arc surface of the part faces upward, the height of the edges on both sides is less than the thickness of the part. When the arc surface of the part faces downward, the flat surface faces upward, and the height of the edges on both sides is equal to the thickness of the part. Therefore, when the pressure sensor 52 descends, although the pressure signal can be detected by contacting the part, the piston end of the electric push rod 51 is The strokes are different, so the direction of the part can be determined based on the stroke of the piston end of the electric push rod 1 51 when the pressure sensor 52 detects pressure, and because the two pressure sensors 52 are respectively aligned with the two edges of the part, when both are in contact with the part at the same time, the part is evenly stressed and will not tilt due to the arc surface facing downward; the detection information is transmitted to the controller, and if the arc surface of the part faces downward, the motor 2 13 drives the threaded rod 2 12 to rotate, so that the crossbeam 2 8 moves horizontally on the bottom plate 2, so that the two clamping plates 19 extend between the two feeding plates 5, and at the same time, the cylinder 15 is used to drive the mounting plate 16 to descend, so that a part is in Between the two clamping plates 19, the flip block 20 is aligned with the part, and under the action of the motor three 17 driving the bidirectional threaded rod one 18 to rotate, the two flip blocks 20 are brought close to each other to clamp the part, and then the part is driven to rise, the motor five 26 drives the flip block 20 to rotate, so that the part rotates one hundred and eighty degrees, and then the flipped part is driven to move to the conveyor belt one 3. Repeating the above operation can make each part face flat downward, which not only avoids the shaking and deviation of the parts due to the arc surface facing downward, but also ensures the uniform orientation of each part, thereby further ensuring the continuity and efficiency of the subsequent processing of the parts.

[0061] In this embodiment, Figure 1 , Figure 12 , Figure 13 As shown, one end of the slider 14 is threadedly connected to a threaded rod 11, both ends of the threaded rod 11 are rotatably set on the crossbeam 2 8, one side of the upper end of the crossbeam 2 8 is fixedly connected to a motor 10, and the output end of the motor 10 is fixedly connected to one end of the threaded rod 11.

The end of the spring 34 away from the telescopic plate 32 is fixedly connected with one side of the inner cavity of the groove plate 33.

[0064] One side of the transverse moving block 35 is threadedly connected with a fourth threaded rod 36. Both ends of the fourth threaded rod 36 are rotatably arranged on the first frame 1. One side of the first frame 1 is fixedly connected with a tenth motor 54. The output end of the tenth motor 54 is fixedly connected with one end of the fourth threaded rod 36. One side of the lower end surface of the transverse moving block 35 is fixedly connected with a fourth cylinder 37. The piston end of the fourth cylinder 37 is fixedly connected with one side of the lifting plate 39.

The output end of the seventh motor 40 is fixedly connected with one end of the third bidirectional threaded rod 41. One side of the limiting plate 42 is threadedly connected with a fifth threaded rod 44. One end of the fifth threaded rod 44 is rotatably arranged on the lifting plate 39. One side of the lifting plate 39 is fixedly connected with an eighth motor 43. The output end of the eighth motor 43 is fixedly connected with one end of the fifth threaded rod 44.

[0065] Specifically, in the above embodiment, although the parts can be separated and fed to avoid chaotic feeding, in some cases, it is necessary to feed the parts in batches to meet different usage requirements, such as packaging, storage, etc. When feeding in batches, the number of parts in each batch needs to be the same. However, when the parts are arranged on the first conveyor belt 3, they are only in a single row, which will cause the arrangement of a batch of parts on the first conveyor belt 3 to be too long and not easy to perform operations such as packaging and storage. Therefore, to solve this problem, the working principle of this embodiment is as follows:

[0066] Whenever a part is placed on the first conveyor belt 3, since the first motor 10 drives the first threaded rod 11 to rotate, the slider 14 can move horizontally in the chute of the second cross beam 8. Therefore, the position of the clamping plate 19 in the X, Y, and Z axes directions can be adjusted, and the part can be clamped by the flipping block 20 and the orientation of the part on the first conveyor belt 3 can be changed to make the parts arranged in multiple rows, so as to reduce the total length of the arrangement of the same batch of parts on the first conveyor belt 3. When the same batch of parts moves to the designated position, since the same batch of parts are arranged in multiple rows in an orderly manner and the total length is reduced, it is convenient to perform operations such as unified packaging and storage of the parts;

[0067] Moreover, although the parts can be placed in multiple rows in an orderly manner by the clamping plate 19, during the movement of the parts, they may be offset due to external force factors, affecting subsequent operations such as packaging. Therefore, to avoid this situation, after the flipping block 20 clamps the parts, the parts are placed one by one along the edge of the lifting plate 39. And the distance between the lifting plate 39 and the limiting plate 42 and the distance between the two groove plates 33 can be adjusted by driving the rotation of the bidirectional threaded rod three 41 by the motor seven 40 and driving the rotation of the threaded rod five 44 by the motor eight 43. At the same time, when the limiting plate 42 moves, the telescopic plate 32 will also slide at the groove plate 33. Under the action of the spring 34, the telescopic plate 32 is kept in close contact with the limiting plate 42, so that the placed parts are limited by the lifting plate 39, the telescopic plate 32, the groove plate 33, and the limiting plate 42. When the conveyor belt one 3 moves, the motor ten 54 drives the rotation of the threaded rod four 36, the transverse movement block 35 moves transversely, and the lifting plate 39 moves synchronously with the conveyor belt one 3. During the entire feeding process, the parts are in a limited state, thus avoiding the situation that the parts are offset due to external force and then affecting subsequent operations such as packaging. When the lifting plate 39 reaches the designated position, the lifting plate 39 is driven to rise by the cylinder four 37 to make it away from the parts, and then it can be reset. And because the feeding auxiliary components are arranged on both sides of the frame one 1, the equipment for operating the parts can be arranged on both sides of the frame one 1, and the two groups of feeding auxiliary components limit the parts, which is beneficial to improving the work efficiency.

[0068] In this embodiment, as Figure 10 , Figure 11 shown, an anti-overlapping component is further provided on the cross beam one 4;

[0069] The anti-overlapping component includes a cylinder two 21 fixedly connected to one side of the upper end surface of the cross beam one 4. The piston end of the cylinder two 21 is fixedly connected with an anti-overlapping plate two 28. The anti-overlapping plate two 28 is inserted and slidably connected with an anti-overlapping plate one 27. One side of the anti-overlapping plate one 27 is threadedly connected with a threaded rod three 31. One end of the threaded rod three 31 is rotatably arranged on the anti-overlapping plate two 28. One end of the anti-overlapping plate two 28 is fixedly connected with a motor six 30. The output end of the motor six 30 is fixedly connected with one end of the threaded rod three 31.

[0070] Specifically, in the above embodiment, when the baffle 47 blocks the parts, since the subsequent parts are in a continuous motion state, when the arc surface of the part faces downward, the part may move above the part blocked by the baffle 47, resulting in overlapping of the parts and affecting subsequent feeding. Therefore, to avoid this problem, according to the length of the part, the motor six 30 drives the threaded rod three 31 to rotate, so that the anti-overlap plate one 27 slides on the anti-overlap plate two 28 until the end of the anti-overlap plate one 27 is above the end of the part blocked by the baffle 47. Under the action of the cylinder two 21, the anti-overlap plate one 27 is driven to descend, so that the anti-overlap plate one 27 is almost in contact with the part. At this time, when the subsequent part presses the part blocked by the baffle 47, it will not overlap due to the block of the anti-overlap plate one 27, thus avoiding the situation that when the baffle 47 blocks the part, due to the continuous motion of the subsequent part and the arc surface of the part facing downward, the part moves above the part blocked by the baffle 47, which in turn leads to overlapping of the parts and affects subsequent feeding. At the same time, it does not affect the clamping of the part at the end of the feeding plate 5 by the flipping block 20.

[0071] Working principle: According to the thickness and width of the parts when they are laid flat, the motor 4 25 drives the two-way threaded rod 24 to rotate, and adjusts the spacing between the two threaded blocks 23 and the feeding plate 5 until the minimum spacing between the two feeding plates 5 is greater than the width of one part and less than the width of two parts. At the same time, the cylinder 3 22 is used to drive the partition plate 29 to move up and down, and adjust the spacing between the bottom of the partition plate 29 and the upper surface of the conveyor belt 2 6, and this spacing is greater than the thickness of a part when laid flat and less than the thickness of two parts stacked; then the parts are added to the conveyor belt 2 6, and the conveyor belt 2 6 is driven to operate. Since the handrail movement channel composed of the two feeding plates 5 is from wide to narrow, the parts will Due to the operation of the conveyor belt 2 6, the parts are gathered at the narrowest part of the feeding plate 5. Since the partition plate 29 cooperates with the feeding plate 5 to form a parts entrance, and only one part can pass through the entrance at a time, the parts will be arranged at the narrowest part of the distance between the two feeding plates 5, and then the parts will be fed to the conveyor belt 1 3 in turn. The conveyor belt 1 3 drives the parts to move for feeding, thereby not only realizing the separate feeding of multiple parts and avoiding feeding confusion, but also making the angle of each part uniform, thereby improving the continuity and efficiency of subsequent processing of the parts; although the angle of each part can be made uniform by the above method, in some cases, one side of the part is an arc surface, which is to adapt to the natural bending of the arm. When multiple parts are arranged between the feed plates 5, their arc surfaces may face upward or downward. When the arc surface faces downward, the parts are prone to shaking and shifting due to the small contact area between the arc surface and the conveyor belt 3, resulting in the multiple parts on the conveyor belt 3 being uneven and not in uniform orientation, which still affects the continuity of subsequent processing. Therefore, in order to solve the above problem, when the parts are between the two feed plates 5, the baffle 47 is used to block the parts, and the motor 9 48 is used to drive the threaded rod 6 50 to rotate, so that the adjustment plate 53 moves horizontally, and the distance between the two pressure sensors 52 is adjusted so that the distance is equal to the length of a part, and then the electric push rods 51 on both sides are started at the same time to drive the pressure sensors 52 to move horizontally. The pressure sensor 52 is lowered until the pressure sensor 52 contacts the two ends of the part. When the arc surface of the part faces upward, the height of the edges on both sides is less than the thickness of the part. When the arc surface of the part faces downward, the plane faces upward, and the height of the edges on both sides is equal to the thickness of the part. Therefore, when the pressure sensor 52 is lowered, although the pressure signal can be detected by contacting the part, the stroke of the piston end of the electric push rod 51 is different. Therefore, the direction of the part can be judged according to the stroke of the piston end of the electric push rod 51 when the pressure sensor 52 detects the pressure. In addition, since the two pressure sensors 52 are respectively aligned with the two edges of the part, when both are in contact with the part at the same time, the part is evenly stressed and will not be lifted due to the arc surface facing downward.The detection information is transmitted to the controller. If the arc surface of the part faces downward, the second motor 13 drives the second threaded rod 12 to rotate, causing the second crossbeam 8 to move horizontally on the bottom plate 2, so that the two clamping plates 19 extend between the two feeding plates 5. At the same time, the first cylinder 15 drives the mounting plate 16 to descend, so that a part is located between the two clamping plates 19, and the flipping block 20 is aligned with the part. Under the action of the third motor 17 driving the first bidirectional threaded rod 18 to rotate, the two flipping blocks 20 approach each other to clamp the part, and then the part is driven to rise. The fifth motor 26 drives the flipping block 20 to rotate, so that the part rotates 180 degrees, and then the flipped part is driven to move onto the first conveyor belt 3. By repeating the above operations, each part can be made to face downward flat, which not only avoids the situation of shaking and offset of the part due to the arc surface facing downward, but also ensures the uniform orientation of each part, thus further ensuring the continuity and efficiency of the subsequent processing of the part. Whenever a part is placed on the first conveyor belt 3, since the first motor 10 drives the first threaded rod 11 to rotate and the slider 14 can move horizontally at the sliding groove of the second crossbeam 8, the position of the clamping plate 19 in the X, Y, and Z axis directions can be adjusted to pick up the part by using the flipping block 20 and change the orientation of the part on the first conveyor belt 3, so that the parts are arranged in multiple rows to reduce the total length of the arrangement of the same batch of parts on the first conveyor belt 3. When the same batch of parts moves to the specified position, since the same batch of parts are placed in multiple rows in an orderly manner and the total length is reduced, it is convenient to perform operations such as unified packaging and storage of the parts;Moreover, although the parts can be placed in multiple rows in an orderly manner by the clamping plate 19, during the movement of the parts, they may be offset due to external force factors, affecting subsequent operations such as packaging. Therefore, to avoid this situation, after the flipping block 20 clamps the parts, the parts are placed one by one along the edge of the lifting plate 39. And the distance between the lifting plate 39 and the limiting plate 42 and the distance between the two groove plates 33 can be adjusted by driving the rotation of the bidirectional threaded rod three 41 by the motor seven 40 and driving the rotation of the threaded rod five 44 by the motor eight 43. At the same time, when the limiting plate 42 moves, the telescopic plate 32 will also slide at the groove plate 33, and the telescopic plate 32 is kept in close contact with the limiting plate 42 under the action of the spring 34, so that the placed parts are limited by the lifting plate 39, the telescopic plate 32, the groove plate 33, and the limiting plate 42. When the conveyor belt one 3 moves, the motor ten 54 drives the rotation of the threaded rod four 36, the transverse movement block 35 moves transversely, and the lifting plate 39 moves synchronously with the conveyor belt one 3. During the entire feeding process, the parts are in a limited state, thus avoiding the situation that the parts are offset due to external force, which in turn affects subsequent operations such as packaging. When the lifting plate 39 reaches the specified position, the lifting plate 39 is driven to rise by the cylinder four 37, so that it is far away from the parts, and then it can be reset. And because the feeding auxiliary components are arranged on both sides of the frame one 1, the equipment for operating the parts can be arranged on both sides of the frame one 1, and the two groups of feeding auxiliary components limit the parts, which is beneficial to improving the work efficiency. According to the length of the parts, the motor six 30 drives the rotation of the threaded rod three 31, so that the anti-overlapping plate one 27 slides on the anti-overlapping plate two 28 until the end of the anti-overlapping plate one 27 is above the end of the part blocked by the baffle 47, and under the action of the cylinder two 21, the anti-overlapping plate one 27 is driven to descend so that the anti-overlapping plate one 27 is almost in contact with the part. At this time, when the subsequent parts squeeze the parts blocked by the baffle 47, they will not overlap due to the blocking of the anti-overlapping plate one 27, thus avoiding the situation that when the baffle 47 blocks the parts, because the subsequent parts are in a continuous movement state, when the arc surface of the part faces down, the part moves above the part blocked by the baffle 47, resulting in the overlapping of the parts and affecting the subsequent feeding, and at the same time, it does not affect the clamping of the parts at the end of the feeding plate 5 by the flipping block 20.;
