Technical Field

[0001] This invention belongs to the technical field of stacking devices, and specifically relates to a trapezoidal packaging stacking device. Background Technology

[0002] Modern televisions, monitors, and other similar products typically use rectangular packaging. However, these products are inherently wider at the bottom and narrower at the top. Using traditional rectangular packaging wastes packaging materials and space, leading to wasted logistics resources and hindering sustainable resource development. Trapezoidal packaging, which better suits the product, can solve this problem. This requires specially designed stacking devices suitable for trapezoidal packaging. Summary of the Invention

[0003] In view of the problems mentioned in the background art, the purpose of this invention is to provide a trapezoidal packaging stacking device to solve the problems mentioned in the background art.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A trapezoidal packaging stacking device includes a conveying assembly and a stacking plate. The stacking plate is installed on the side of a conveyor belt. Along the conveying direction, the side of the conveyor belt is sequentially equipped with a turning mechanism for intermittently turning packaging boxes and a turning mechanism for pushing forward and reverse packaging boxes to the stacking plate. The stacking plate is equipped with stacking mechanisms.

[0006] As a preferred technical solution, the conveying component includes a diversion conveyor belt, which includes a main conveyor belt, a secondary conveyor belt one, and a secondary conveyor belt two. A diverter is installed at the intersection of the main conveyor belt, the secondary conveyor belt one, and the secondary conveyor belt two, and a limit bar is installed above the main conveyor belt.

[0007] As a preferred technical solution, the diverter includes a driving component and a diverting barrier assembly. The driving component and the limiting barrier are rotatably connected to the diverting barrier assembly. When the diverting barrier assembly is stationary, the rotating barrier of the diverting barrier assembly is parallel to the inflow ends of the first and second auxiliary conveyor belts, respectively.

[0008] As a preferred technical solution, the turning mechanism includes a reciprocating mechanism, a horizontal flipping mechanism, and a clamping mechanism. The clamping mechanism is installed on the output end of the horizontal flipping mechanism, and the horizontal flipping mechanism is installed on the output end of the reciprocating mechanism.

[0009] As a preferred technical solution, the driving direction of the reciprocating mechanism is vertical or horizontal and perpendicular to the conveying direction of the conveying component.

[0010] As a preferred technical solution, the assembly mechanism includes, in sequence, a second feeding device and a first feeding device along the conveying direction, with the output ends of both the second feeding device and the first feeding device facing the conveying component.

[0011] As a preferred technical solution, there are connecting plates one and two connecting plates between the conveying component and the stacking plate, and the tops of connecting plates one, two connecting plates, the linear conveyor belt and the stacking plate are flush.

[0012] As a preferred technical solution, connecting plate one and connecting plate two are located directly below the output ends of feeding device one and feeding device two, respectively. The extension distances of feeding device two and feeding device one are equal, the lengths of connecting plate one and connecting plate two are equal, and the sum of the lengths of connecting plate one and the packaging box is less than the extension distance of feeding device one.

When the output end of the drive component extends to its maximum length, the distance between the output end and the side of the connecting plate away from the turning mechanism is not less than the sum of the top and bottom ends of the trapezoid of the packaging box. When the output end extends to its minimum length, the output end does not exceed the side of the connecting plate that is close to the turning mechanism.

[0014] As a preferred technical solution, it also includes an anti-tipping frame, which slides in contact with the top of the stacking plate and is located on the side of the connecting plate away from the turning mechanism.

[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Example 1

[0027] refer to Figures 1 to 5 The trapezoidal packaging stacking device described in this embodiment includes a conveying component. Preferably, the conveyor belt is a diversion conveyor belt 1, which includes a main conveyor belt 11, a secondary conveyor belt 12 and a secondary conveyor belt 2 13. A diverter 15 is installed at the intersection of the main conveyor belt 11, the secondary conveyor belt 12 and the secondary conveyor belt 2 13.

[0028] Limit bars 14 are installed above the main conveyor belt 11, and the distance between the limit bars 14 is equal to the length of the packaging box.

[0029] Preferably, limit plates are installed on the edges of both the first secondary conveyor belt 12 and the second secondary conveyor belt 13, and the widths of both the first secondary conveyor belt 12 and the second secondary conveyor belt 13 are equal to those of the packaging box.

[0030] The diverter 15 includes a drive unit and a diverter assembly. The drive unit and the limit bar 14 are rotatably connected to the diverter assembly. The drive unit drives the diverter assembly to rotate repeatedly to both sides at regular intervals.

[0031] As a preferred embodiment, the drive unit includes a support frame 151 and a cylinder 152. The cylinder 152 is rotatably mounted on the support frame 151 via a mounting plate 155, and the output end of the cylinder 152 is rotatably connected to the diverter assembly.

[0032] As a preferred embodiment, the diversion barrier assembly includes two sets of rotating barriers 153 and a connecting rod 154. The limiting barrier 14 and the rotating barriers 153 are rotatably connected. The two sets of rotating barriers 153 are rotatably connected to the connecting rod 154 respectively. The output end of the cylinder 152 is rotatably connected to one of the sets of rotating barriers 153.

[0033] When cylinder 152 is extended to its longest and shortest positions, the inflow ends of secondary conveyor belt 12 and secondary conveyor belt 2 are parallel to the two sets of rotating bars 153, respectively.

[0034] Packaging boxes are sequentially conveyed from the main conveyor belt 11 between the limit bars 14 towards the diverter 15. The diverter 15 guides the packaging boxes one by one onto the secondary conveyor belt 12 and the secondary conveyor belt 2 13. The specific working principle is as follows: the cylinder 152 extends and retracts, causing the rotating bar 153 to repeatedly face the secondary conveyor belt 12 and the secondary conveyor belt 2 13. The connecting rod 152 drives another set of rotating bars 152 to rotate synchronously. When the cylinder 152 extends to its longest end, the rotating bar 153 is parallel to the inflow end of the secondary conveyor belt 2 13, and the packaging box is guided onto the secondary conveyor belt 2 13. When the cylinder 152 retracts to its shortest end, the rotating bar 153 is parallel to the inflow end of the secondary conveyor belt 12, and the packaging box is guided onto the secondary conveyor belt 12.

[0035] A turning mechanism is installed on one side of the secondary conveyor belt 12. The turning mechanism includes a reciprocating mechanism 2, a horizontal flipping mechanism 3, and a clamping mechanism 4. The clamping mechanism 4 is installed on the output end of the horizontal flipping mechanism 3, which is also installed on the output end of the reciprocating mechanism 2. The output end of the reciprocating mechanism 2 moves up and down vertically or moves closer to or further away from the secondary conveyor belt 12 horizontally. The horizontal flipping mechanism 3 drives the clamping mechanism 4 to rotate 180 degrees intermittently.

[0036] As a preferred embodiment, the reciprocating mechanism 2 includes a mounting frame 21 in the shape of an E. A motor 22 is mounted on the bottom of the mounting frame 21. A lead screw 23 is rotatably mounted on the mounting frame 21 along its length. The lead screw 23 is fixedly connected to the output end of the mounting frame 21. A movable block 24 is threaded onto the lead screw 23. A limit slider is connected to the movable block 24. A limit groove is formed on the side wall of the mounting frame 21. The limit slider slides vertically within the limit groove.

[0037] Motor 22 drives lead screw 23 to rotate, and lead screw 23 drives movable block 24 to rise and fall along the limit slide groove.

[0038] As a preferred embodiment, the horizontal flipping mechanism 3 includes a second motor 31 mounted on the movable block 24, an L-shaped rod 32 mounted on the output end of the second motor 31, a mounting plate 33 mounted on the end of the L-shaped rod 32, and a clamping mechanism 3 mounted on the mounting plate 33.

[0039] Motor 2 31 drives L-shaped rod 32 to rotate 180 degrees, L-shaped rod 32 drives mounting plate 33 to rotate 180 degrees, thereby driving clamping mechanism 3 to rotate 180 degrees.

[0040] As a preferred embodiment, the clamping mechanism 4 includes a straight clamping plate 41 fixedly mounted on the mounting plate 33 and an inclined clamping plate 42 slidably mounted on the mounting plate 33. The inclined clamping plate 42 is parallel to the inclined side of the trapezoidal package. A motor 43 is mounted on the straight clamping plate 41, and a lead screw 44 is mounted on the output end of the motor 43. The lead screw 44 is threadedly connected to the inclined clamping plate 42.

[0041] When the packaging box moves to the reversing position, the reciprocating mechanism 2 drives the horizontal flipping mechanism 3 to descend, so that the packaging box is located between the straight clamping plate 41 and the inclined clamping plate 42. Then, the clamping mechanism 4 clamps the packaging box. Finally, the horizontal flipping mechanism 3 drives the clamping mechanism 4 to flip 180 degrees away from the diverter 15, so that the top and bottom of the packaging box are reversed. After the reversal is completed, the above actions are reversed, that is, the clamping mechanism 4 releases the packaging box. Then, the reciprocating mechanism 2 drives the horizontal flipping mechanism 3 to rise and remove the limit on the packaging box. The reversed packaging box is driven by the auxiliary conveyor belt 12 to continue moving. Before the next packaging box arrives, the horizontal flipping mechanism 3 flips 180 degrees again to complete the reset.

[0042] The assembly mechanism 5 includes a first feeding device and a second feeding device, which are respectively installed on both sides of the first secondary conveyor belt 12 and the second secondary conveyor belt 13. The second feeding device is closer to the main conveyor belt 11 than the first feeding device.

[0043] As a preferred embodiment, the feeding device includes a cylinder 51, a push plate 52 is installed on the output end of the cylinder 51, and a connecting plate 53 is connected to the secondary conveyor belt 12 in the extension and retraction direction of the cylinder 51. The connecting plate 53 is flush with the top end of the secondary conveyor belt 12.

[0044] Cylinder 51 pushes the forward-facing packaging box of the auxiliary conveyor belt 12 along the connecting plate 53 to the stacking plate 61 via push plate 52.

[0045] As a preferred embodiment, the feeding device 2 includes a cylinder 2 54, a push plate 2 55 is installed on the output end of the cylinder 2 54, and a connecting plate 2 56 is connected to the secondary conveyor belt 2 13 in the extension and retraction direction of the cylinder 2 54. The connecting plate 2 56 is flush with the top end of the secondary conveyor belt 2 13.

[0046] Cylinder 2 54 pushes the reverse packaging box of auxiliary conveyor belt 2 13 along connecting plate 2 56 to stacking plate 61 via push plate 2 55.

[0047] Preferably, limit plates are installed on the edges of both connecting plate 53 and connecting plate 56.

[0048] The limiting plate prevents the packaging box from tipping over during movement.

[0049] A stacking plate 61 is installed between the secondary conveyor belt 12 and the secondary conveyor belt 2. Both the connecting plate 1 53 and the connecting plate 2 56 are connected to the stacking plate 61 and are flush with the top of the stacking plate 61. A stacking mechanism 6 is installed on the end of the stacking plate 61 near the main conveyor belt 11.

[0050] Preferably, the stacking mechanism 6 includes a cylinder 62, and a pusher plate 63 is installed on the output end of the cylinder 62. The extension and retraction direction of the cylinder 62 is consistent with the length direction of the stacking plate 61. When the cylinder 62 is extended to its maximum length, the distance between the pusher plate 63 and the side of the connecting plate 53 away from the separator 15 is not less than the sum of the top and bottom ends of the trapezoidal shape of the packaging box. When the cylinder 62 is extended to its minimum length, the pusher plate 63 does not exceed the side of the connecting plate 56 near the separator 15.

[0051] Preferably, it also includes an anti-tipping frame 64, which slides in contact with the top of the stacking plate 61 and is located on the side of the connecting plate 53 away from the turning mechanism.

[0052] Assembly mechanism 5 pushes the forward-facing packaging boxes on secondary conveyor belt 2 13 onto stacking plate 61 and pushes the reverse-facing packaging boxes on secondary conveyor belt 1 12 onto stacking plate 61. Cylinder 3 62 pushes the forward-facing packaging boxes and the reverse-facing packaging boxes into contact through push plate 3 63, so that the oblique edges of the forward-facing packaging boxes and the reverse-facing packaging boxes are engaged. This process is repeated to complete the stacking. Anti-tipping frame 64 supports the packaging boxes to prevent them from falling over during the pushing process and causing stacking failure.

[0053] Example 2

[0054] refer to Figures 1-6 The trapezoidal packaging stacking device described in this embodiment has a conveying component consisting of a linear conveyor belt and a stacking plate 61. The stacking plate 61 is installed on one side of the linear conveyor belt, and a turning mechanism and an assembly mechanism 5 are installed sequentially on the other side along the conveying direction. The assembly mechanism 5 includes a feeding device 1 and a feeding device 2, which are installed on the same side of the linear conveyor belt. A stacking mechanism 6 is installed on the stacking plate 61.

[0055] The turning mechanism and stacking mechanism 6 are the same as the turning mechanism in Example 1.

[0056] The connecting plate 53 included in the first feeding device and the connecting plate 56 included in the second feeding device are both installed between the linear conveyor belt and the stacking plate 61. The tops of the connecting plate 53, the connecting plate 56, the linear conveyor belt and the stacking plate 61 are flush.

[0057] The linear conveyor belt is used to transport packaging boxes. The turning mechanism intermittently flips the next set of packaging boxes 180 degrees. The feeding device 1 and feeding device 2 push the forward and reverse packaging boxes onto the stacking plate 61 in sequence, and the stacking mechanism 6 pushes the forward packaging boxes to contact and stack the reverse packaging boxes.
