Description

Technical Field

[0001] This invention relates to the field of product traying technology, and in particular to an automatic adjustment production line compatible with multiple products. Background Technology

[0002] With the rapid development of industry, products closely related to human work and life, such as 3C, new energy, and smart logistics, are being updated at an increasingly faster pace. This requires automation equipment to be more and more compatible. Dedicated equipment has been gradually phased out by the era of rapid development, and highly compatible equipment has become a trend in the future automation industry.

[0003] A carrier return mechanism generally includes a carrier that matches the product size and an ear plate chain assembly that drives the carrier's cyclical movement. Existing carriers generally fall into two categories: fixed-size and adjustable-size. Fixed-size carriers have a fixed size and can only accommodate products of one size. When different sizes of products need to be transported, different-sized carriers must be replaced, resulting in a lack of carrier compatibility, high equipment costs, and reduced production efficiency. Adjustable-size carriers are adjustable in size, and can be further divided into manual and automatic adjustments. Manual adjustment of adjustable-size carriers affects production efficiency, while automatic adjustment carriers have a more complex structure and higher equipment costs. How to make carriers compatible with multiple products, with a simple structure, low cost, and without affecting production efficiency when adjusting sizes is a pressing technical problem to be solved in this field. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is how to make the carrier compatible with a variety of products, simple in structure, low in cost, and not affect production efficiency when adjusting size.

[0005] To solve the above-mentioned technical problems, the present invention provides an automatic adjustment assembly line compatible with multiple products. The product to be conveyed is rectangular in shape, having four bottom corners and four bottom edges. The automatic adjustment assembly line includes a first chain mechanism, a second chain mechanism, and a rotary power mechanism. The first chain mechanism and the second chain mechanism are arranged sequentially along the horizontal X-axis. The first chain mechanism includes a first lug chain, the sprocket of which rotates around the horizontal X-axis. The second chain mechanism includes a second lug chain, the sprocket of which rotates around the horizontal X-axis. The rotary power mechanism is used to drive the sprockets of the first lug chain and the second lug chain to rotate.

[0006] The first ear plate chain is connected to a plurality of first tooling block assemblies evenly distributed along its circumference. Each first tooling block assembly includes a first corner-shaped tooling block and a first edge-shaped tooling block arranged sequentially in a clockwise direction. The second ear plate chain is connected to a plurality of second tooling block assemblies evenly distributed along its circumference. Each second tooling block assembly includes a second corner-shaped tooling block and a second edge-shaped tooling block arranged sequentially in a clockwise direction.

[0007] When the automatic adjustment conveyor line transports products, the plurality of first tooling block assemblies and the plurality of second tooling block assemblies form a plurality of support and limiting carriers arranged sequentially around the horizontal X-axis. Each support and limiting carrier includes a first tooling block assembly and a second tooling block assembly. Each product to be conveyed corresponds to one support and limiting carrier. The first corner-shaped tooling block and the second corner-shaped tooling block support and limit the two bottom corners of the corresponding product to be conveyed in a corner-shaped manner. The first edge-shaped tooling block and the second edge-shaped tooling block support and limit the two bottom edges of the corresponding product to be conveyed in an edge-shaped manner. The rotary power mechanism drives the first ear plate chain and the second ear plate chain to move in the same direction and at the same speed.

[0008] When the automatic adjustment assembly line adjusts the size, the rotary power mechanism drives the first ear plate chain and the second ear plate chain to move at different speeds to adjust the relative positions of the first tooling block assembly and the second tooling block assembly of the same support and limiting carrier.

[0009] In one embodiment of the present invention, when the automatic adjustment assembly line conveys products, the rotary power mechanism drives the sprockets of the first ear plate chain and the second ear plate chain to rotate clockwise synchronously. When the automatic adjustment assembly line adjusts the size, the rotary power mechanism drives the sprockets of the first ear plate chain to rotate counterclockwise, while the sprockets of the second ear plate chain remain stationary.

[0010] In one embodiment of the present invention, the rotary power output shaft of the rotary power mechanism drives the sprocket of the first ear plate chain to rotate in both forward and reverse directions. The rotary power mechanism drives the sprocket of the second ear plate chain to rotate through a ratchet mechanism. When the rotary power output shaft of the rotary power mechanism rotates forward, it drives the sprocket of the second ear plate chain to rotate. When the rotary power output shaft of the rotary power mechanism rotates in reverse, it does not drive the sprocket of the second ear plate chain to rotate.

[0011] In one embodiment of the present invention, when the automatic adjustment assembly line conveys products, the first corner-shaped tooling block and the second edge-shaped tooling block are aligned along the horizontal X-axis direction, and the second corner-shaped tooling block and the first edge-shaped tooling block are aligned along the horizontal X-axis direction.

[0012] In one embodiment of the present invention, each of the first tooling block components further includes a third edge-enclosing tooling block, wherein the first corner-enclosing tooling block, the first edge-enclosing tooling block, and the third edge-enclosing tooling block are arranged sequentially in a clockwise direction, and each of the second tooling block components further includes a fourth edge-enclosing tooling block, wherein the second corner-enclosing tooling block, the second edge-enclosing tooling block, and the fourth edge-enclosing tooling block are arranged sequentially in a counterclockwise direction.

[0013] In one embodiment of the present invention, when the automatic adjustment assembly line conveys products, the first corner-shaped tooling block is aligned with the fourth edge-shaped tooling block or the second edge-shaped tooling block along the horizontal X-axis direction, and the second corner-shaped tooling block is aligned with the third edge-shaped tooling block or the first edge-shaped tooling block along the horizontal X-axis direction.

[0014] In one embodiment of the present invention, the first chain mechanism and the second chain mechanism are movable relative to each other along the horizontal X-axis direction, the rotary power mechanism is mounted on the frame of the first chain mechanism, and the rotary power mechanism and the second chain mechanism are movable relative to each other along the horizontal X-axis direction and maintain transmission.

[0015] In one embodiment of the present invention, the rotary power mechanism drives the second ear plate chain to move via a sliding transmission shaft that can slide along the horizontal X-axis direction.

[0016] In one embodiment of the present invention, the rotary power output shaft of the rotary power mechanism includes a first shaft segment and a second shaft segment. The first shaft segment is driven by a sprocket of the first lug chain. The cross-section of the second shaft segment is non-circular. The second shaft segment extends into a bushing. The inner hole of the bushing has a non-circular cross-section. The bushing is connected to a sleeve that fixes a ratchet. The second shaft segment and the bushing can slide axially and rotate.

[0017] The sliding drive shaft includes a third shaft section and a fourth shaft section. The third shaft section drives the sprocket shaft of the second lug chain. The fourth shaft section has a non-circular cross-section and extends into the inner hole of the ratchet. The fourth shaft section and the ratchet are axially sliding and rotatable.

[0018] In one embodiment of the present invention, a slide rail mechanism and a translational force mechanism are further included. The slide rail mechanism is used to guide the first chain mechanism and / or the second chain mechanism to move along the horizontal X-axis direction, and the translational force mechanism is used to drive the first chain mechanism and / or the second chain mechanism to move along the horizontal X-axis direction.

[0019] The technical solution of the present invention has the following advantages compared with the prior art:

[0020] 1) The automatic adjustment production line compatible with multiple products described in this invention has multiple first tooling block assemblies connected on a first ear plate chain and multiple second tooling block assemblies connected on a second ear plate chain. The relative positions of the first and second tooling block assemblies of the same support and limiting carrier can be adjusted, thereby adjusting the size of the support and limiting carrier along the horizontal Y-axis. The size of the support and limiting carrier is cleverly adjusted by a rotational power mechanism. The support and limiting carrier is compatible with multiple products, has a simple structure, low cost, and does not affect production efficiency when adjusting the size.

[0021] 2) The automatic adjustment production line compatible with multiple products described in this invention drives the rotation of the second ear plate chain through a sliding transmission shaft that can slide relative to it via the rotation power output shaft of the rotation power mechanism, and drives the second chain mechanism to move through the translational power mechanism, thereby adjusting the size of the support and limiting carrier along the horizontal X-axis direction.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0033] Example 1

[0034] See Figures 1 to 8 As shown, an automatic adjustment assembly line compatible with multiple products is disclosed. The product to be conveyed, 1, is rectangular in shape and has four bottom corners 11 and four bottom edges 12. The automatic adjustment assembly line includes a first chain mechanism 2, a second chain mechanism 3, and a rotary power mechanism 4. The first chain mechanism 2 and the second chain mechanism 3 are arranged sequentially along the horizontal X-axis. The first chain mechanism 2 includes a first ear plate chain 21, and the sprocket of the first ear plate chain 21 rotates around the horizontal X-axis. The second chain mechanism 3 includes a second ear plate chain 31, and the sprocket of the second ear plate chain 31 rotates around the horizontal X-axis. The rotary power mechanism 4 is used to drive the sprockets of the first ear plate chain 21 and the second ear plate chain 31 to rotate.

[0035] The first ear plate chain 21 is connected to a plurality of first tooling block assemblies 5 evenly distributed along its circumference. Each first tooling block assembly 5 includes a first corner-shaped tooling block 51 and a first edge-shaped tooling block 52 arranged sequentially in a clockwise direction. The second ear plate chain 31 is connected to a plurality of second tooling block assemblies 6 evenly distributed along its circumference. Each second tooling block assembly 6 includes a second corner-shaped tooling block 61 and a second edge-shaped tooling block 62 arranged sequentially in a clockwise direction.

[0036] When the automatic adjustment conveyor conveys products, multiple first tooling block assemblies 5 and multiple second tooling block assemblies 6 form multiple support and limiting carriers 7 arranged sequentially around the horizontal X-axis. Each support and limiting carrier 7 includes a first tooling block assembly 5 and a second tooling block assembly 6. Each product to be conveyed corresponds to one support and limiting carrier 7. The first corner-shaped tooling block 51 and the second corner-shaped tooling block 61 support and limit the two bottom corners of the corresponding product to be conveyed 1 in the form of corner wrapping. The first edge-shaped tooling block 52 and the second edge-shaped tooling block 62 support and limit the two bottom edges of the corresponding product to be conveyed 1 in the form of edge wrapping. The rotary power mechanism 4 drives the first ear plate chain 21 and the second ear plate chain 31 to move in the same direction and at the same speed.

[0037] When the automatic adjustment assembly line adjusts the size, the rotary power mechanism 4 drives the first ear plate chain 21 and the second ear plate chain 31 to move at a differential speed to adjust the relative position of the first tooling block assembly 5 and the second tooling block assembly 6 of the same support and limiting carrier 7.

[0038] The first chain mechanism 2 further includes a first chain frame 22, on which the first ear plate chain 21 is mounted. The second chain mechanism 3 further includes a second chain frame 32, on which the second ear plate chain 31 is mounted. The first chain frame 22 and the second chain frame 32 have the same structure, both including a horizontal profile and legs. The horizontal profile extends along the horizontal Y-axis, and the legs are vertically arranged. Depending on the actual arrangement, the rotary power mechanism 4 may be mounted on the first chain frame 22 or the second chain frame 32.

[0039] The aforementioned first corner-shaped tooling block 51 and second corner-shaped tooling block 61 have the same structure, each including three tooling plates connected perpendicularly in pairs. The three tooling plates of the first corner-shaped tooling block 51 and the second corner-shaped tooling block 61 are respectively attached to the bottom, side, and end face of the product to be conveyed. The aforementioned first edge-shaped tooling block 52 and second edge-shaped tooling block 62 have the same structure, each including two tooling plates perpendicular to each other. The two tooling plates of the first edge-shaped tooling block 52 and the second edge-shaped tooling block 62 are respectively attached to the bottom and side of the product to be conveyed.

[0040] When using the equipment for the first time, the adjustable production line needs to be sized. Based on the horizontal Y-axis dimension of the product to be conveyed, the first and second ear plate chains are controlled to move at different speeds. This causes the first tooling block assembly 5 and the second tooling block assembly 6 of the same support and limiting carrier 7 to move relative to each other along the horizontal Y-axis until the distance between the first corner-shaped tooling block 51 and the second corner-shaped tooling block 61 of the same support and limiting carrier 7 matches the Y-axis dimension of the product to be conveyed. The support and limiting carrier can then accommodate products with different Y-axis dimensions. After the adjustable production line sizing is completed, the rotary power mechanism drives the first and second ear plate chains to move in the same direction and at the same speed, at which point product conveying can begin.

[0041] In this preferred embodiment, when the automatic adjustment assembly line is conveying products, the rotary power mechanism 4 drives the sprockets of the first ear plate chain 21 and the second ear plate chain 31 to rotate clockwise synchronously. When the automatic adjustment assembly line is adjusting its size, the rotary power mechanism 4 drives the sprockets of the first ear plate chain 21 to rotate counterclockwise, while the sprockets of the second ear plate chain 31 remain stationary. The rotary power mechanism 4 reverses direction, thus driving only the first ear plate chain 21 to rotate counterclockwise, while the second ear plate chain 31 remains stationary. At this time, the first ear plate chain 21 and the second ear plate chain 31 move at different speeds to adjust the size of the adjustable assembly line. After the size adjustment is completed, the rotary power mechanism 4 rotates clockwise, thus driving the first ear plate chain 21 and the second ear plate chain 31 to move clockwise synchronously, so that the supporting and limiting carrier supports and limits the products according to the adjusted size.

[0042] In the preferred embodiment of this example, the rotary power output shaft of the rotary power mechanism 4 drives the sprocket of the first ear plate chain 21 to rotate in both forward and reverse directions. The rotary power mechanism 4 drives the sprocket of the second ear plate chain 31 to rotate through the ratchet mechanism 41. When the rotary power output shaft of the rotary power mechanism 4 rotates forward, it drives the sprocket of the second ear plate chain 31 to rotate. When the rotary power output shaft of the rotary power mechanism 4 rotates in reverse, it does not drive the sprocket of the second ear plate chain 31 to rotate.

[0043] Specifically, the ratchet mechanism 41 includes a ratchet 411, a sleeve 412, and a pawl 413. The sleeve 412 is coaxially sleeved on the outside of the ratchet 411, and the pawl 413 is connected to the inside of the sleeve 412 and works in conjunction with the ratchet 411. When the rotary power mechanism 4 reverses, it drives the sprocket of the first ear plate chain 21 and the sleeve 412 of the ratchet mechanism to rotate. The sleeve 412 drives the pawl 413 to reverse. At this time, the pawl 413 passes over the ratchet 411, and the rotary power mechanism 4 will not drive the sprocket of the second ear plate chain 31 to rotate. When the rotary power mechanism 4 rotates forward, it drives the sprocket of the first ear plate chain 21 and the sleeve of the ratchet mechanism 41 to rotate forward. The sleeve 412 drives the pawl 413 to rotate. At this time, the pawl 413 drives the ratchet 411 to rotate, and the rotary power mechanism 4 can drive the sprocket of the second ear plate chain 31 to rotate.

[0044] In this preferred embodiment, when the automatic adjustment assembly line is conveying products, the first corner-shaped fixture 51 and the second edge-shaped fixture 62 are aligned along the horizontal X-axis, and the second corner-shaped fixture 61 and the first edge-shaped fixture 52 are also aligned along the horizontal X-axis. In this embodiment, the first corner-shaped fixture 51 and the second corner-shaped fixture 61 respectively support and limit one set of diagonal positions of the bottom surface of the product to be conveyed, and the first edge-shaped fixture 52 and the second edge-shaped fixture 62 respectively support and limit the other set of diagonal positions of the bottom surface of the product to be conveyed. In other embodiments, the first edge-shaped fixture and the second edge-shaped fixture may also be aligned along the horizontal X-axis. In this case, the first corner-shaped fixture and the second corner-shaped fixture respectively support and limit one set of diagonal positions of the bottom surface of the product to be conveyed, and the first edge-shaped fixture and the second edge-shaped fixture respectively support and limit opposite sides of the bottom surface of the product to be conveyed.

[0045] In a preferred embodiment of this example, each first tooling block assembly 5 further includes a third edge-wrapping tooling block 53. The first corner-wrapping tooling block 51, the first edge-wrapping tooling block 52, and the third edge-wrapping tooling block 53 are arranged sequentially in a clockwise direction. Each second tooling block assembly 6 further includes a fourth edge-wrapping tooling block 63. The second corner-wrapping tooling block 61, the second edge-wrapping tooling block 62, and the fourth edge-wrapping tooling block 63 are arranged sequentially in a counterclockwise direction. In the above technical solution, the first corner-wrapping tooling block and the second corner-wrapping tooling block respectively support and limit a set of diagonal positions on the bottom surface of the product to be conveyed. The first edge-wrapping tooling block and the second edge-wrapping tooling block respectively support and limit a set of opposite side positions or another set of diagonal positions on the bottom surface of the product to be conveyed. The third edge-wrapping tooling block and the fourth edge-wrapping tooling block respectively support and limit a set of opposite side positions or another set of diagonal positions on the bottom surface of the product to be conveyed.

[0046] In this preferred embodiment, when the automatic adjustment assembly line is conveying products, the first corner-shaped tooling block 51 is aligned with the fourth edge-shaped tooling block 63 or the second edge-shaped tooling block 62 along the horizontal X-axis, and the second corner-shaped tooling block 61 is aligned with the third edge-shaped tooling block 53 or the first edge-shaped tooling block 52 along the horizontal X-axis. When the product to be conveyed is small in size along the horizontal Y-axis, the first corner-shaped tooling block 51 and the second corner-shaped tooling block 61 respectively support and limit one set of diagonal positions on the bottom surface of the product to be conveyed, and the first edge-shaped tooling block 52 and the second edge-shaped tooling block 62 respectively support and limit the other set of diagonal positions on the bottom surface of the product to be conveyed. When the product to be conveyed has a large dimension along the horizontal Y-axis, the first corner-shaped tooling block 51 and the second corner-shaped tooling block 61 respectively support and limit one set of diagonal positions of the bottom surface of the product to be conveyed, the first edge-shaped tooling block 52 and the second edge-shaped tooling block 62 respectively support and limit one set of opposite side positions of the bottom surface of the product to be conveyed, and the third edge-shaped tooling block 53 and the fourth edge-shaped tooling block 63 respectively support and limit another set of diagonal positions of the bottom surface of the product to be conveyed.

[0047] In this preferred embodiment, the length direction of the product to be conveyed 1 is the horizontal X-axis direction, and the width direction of the product to be conveyed is the horizontal Y-axis direction. The length dimension of the supporting and limiting carrier is the horizontal Y-axis dimension, and the width dimension of the supporting and limiting carrier is the horizontal X-axis dimension. The width dimension of the supporting and limiting carrier is adjusted by the differential motion of the first ear plate chain and the second ear plate chain.

[0048] In this preferred embodiment, the first chain mechanism 2 and the second chain mechanism 3 are movable relative to each other along the horizontal X-axis. A rotary power mechanism 4 is mounted on the frame of the first chain mechanism 2, and the rotary power mechanism 4 and the second chain mechanism 3 are movable relative to each other along the horizontal X-axis and maintain transmission. Through this arrangement, the distance between the first chain mechanism and the second chain mechanism along the horizontal X-axis can be adjusted. At this time, the distance between the first corner-shaped tooling block and the second corner-shaped tooling block of the same support and limiting carrier along the horizontal X-axis can be adjusted. When adjusting the distance between the first chain mechanism and the second chain mechanism along the horizontal X-axis, the rotary power mechanism can maintain transmission with the first ear plate chain and the second ear plate chain, thereby adjusting the dimension of the support and limiting carrier section along the horizontal X-axis. The support and limiting carrier can adapt to products with different X-axis dimensions.

[0049] In the preferred embodiment of this example, the rotary power mechanism 4 drives the second ear plate chain 31 to move via a sliding transmission shaft 42 that can slide along the horizontal X-axis direction.

[0050] Specifically, the rotary power output shaft of the rotary power mechanism includes a first shaft segment 441 and a second shaft segment 442. The first shaft segment is driven by a sprocket of the first lug chain. The cross-section of the second shaft segment is non-circular. The inner hole of the ratchet is non-circular. A sleeve 412 is connected to a bushing 47. The inner hole of the bushing 47 is non-circular. The second shaft segment 442 extends into the inner hole of the bushing 47. The second shaft segment 442 and the bushing 47 can slide axially and rotate.

[0051] The sliding drive shaft 42 is rotatably mounted on the second chain frame 32. The sliding drive shaft 42 includes a third shaft section 421 and a fourth shaft section 422. The third shaft section 421 is connected to the sprocket shaft of the second ear plate chain 31 through a third synchronous belt assembly 48. The cross-section of the fourth shaft section 422 is non-circular. The fourth shaft section 422 extends into the inner hole of the ratchet 411. The fourth shaft section 422 and the ratchet 411 can slide axially and rotate.

[0052] The rotary power mechanism 4 includes a motor 43 and a rotary power output shaft 44. The motor 43 is mounted on the first chain frame 22, and the rotary power output shaft 44 is rotatably mounted on the first chain frame 22. The rotary power output shaft 44 includes a first shaft section 441 and a second shaft section 442. The first shaft section 441 is connected to the rotating shaft of the motor 43 through a first synchronous belt assembly 45. The first shaft section 441 is also connected to the sprocket shaft of the first lug chain 21 through a second synchronous belt assembly 46.

[0053] The cross-section of the second shaft section 442 is non-circular, the inner hole of the ratchet 411 is non-circular, the sleeve 412 is connected to the bushing 47, the inner hole of the bushing 47 is non-circular, the second shaft section 442 extends into the inner hole of the bushing 47, and the second shaft section 442 and the bushing 47 can slide axially and rotate.

[0054] The sliding drive shaft 42 is rotatably mounted on the second chain frame 32. The sliding drive shaft 42 includes a third shaft section 421 and a fourth shaft section 422. The third shaft section 421 is connected to the sprocket shaft of the second ear plate chain 31 through a third synchronous belt assembly 48. The cross-section of the fourth shaft section 422 is non-circular. The fourth shaft section 422 extends into the inner hole of the ratchet 411. The fourth shaft section 422 and the ratchet 411 can slide axially and rotate.

[0055] The aforementioned non-circular shape is preferably a regular polygon, which is easy to process and transmits temperature.

[0056] In a preferred embodiment of this invention, a slide rail mechanism 8 and a translational force mechanism 9 are further included. The slide rail mechanism 8 guides the first ear plate chain 21 and / or the second ear plate chain 31 to move along the horizontal X-axis, and the translational force mechanism 9 drives the first ear plate chain 21 and / or the second ear plate chain 31 to move along the horizontal X-axis. The bottoms of both the first chain frame 22 and the second chain frame 32 are connected to the slide rail mechanism 8, which is mounted on a base plate. The aforementioned translational force mechanism is a cylinder, which pushes the second chain frame to move along the horizontal X-axis, thereby adjusting the distance between the first chain mechanism and the second chain mechanism.

[0057] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
