The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood 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 diverter conveyor belt 1, which includes a main conveyor belt 11, an auxiliary conveyor belt 1 12 and an auxiliary conveyor belt 2 13. A diverter 15 is installed at the intersection of the main conveyor belt 11, the auxiliary conveyor belt 1 12 and the auxiliary conveyor belt 2 13.

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

[0029] Preferably, the edges of the auxiliary conveyor belt 1 12 and the auxiliary conveyor belt 2 13 are both installed with limiting plates, and the widths of the auxiliary conveyor belt 1 12 and the auxiliary conveyor belt 2 13 are both equal to the packaging box.

[0030] The flow divider 15 includes a driving member and a flow divider fence assembly. The driving member and the limit fence 14 are rotatably connected to the flow divider fence assembly respectively. The driving member drives the flow divider fence assembly to rotate to both sides repeatedly at a fixed time.

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

[0032] As a preferred embodiment, the diverter fence assembly includes two groups of rotating fences 153 and connecting rods 154. The limiting fence 14 and the rotating fence 153 are rotatably connected. The two groups of rotating fences 153 are rotatably connected to the connecting rods 154 respectively, and the output end of the cylinder 152 is rotatably connected to one group of rotating fences 153.

[0033] When the cylinder 152 is extended to the longest and shortest positions, the inflow ends of the auxiliary conveyor belt 1 12 and the auxiliary conveyor belt 2 13 are parallel to the two sets of rotating bars 153 respectively.

[0034] The packages are transported from the main conveyor 11 between the limit bars 14 to the diverter 15 in sequence, and the diverter 15 guides the packages to the auxiliary conveyor 12 and the auxiliary conveyor 13 one by one in sequence. The specific working principle is: the cylinder 152 extends and retracts to drive the rotating bar 153 to repeatedly move toward the auxiliary conveyor 12 and the auxiliary conveyor 13, and the connecting rod 152 drives another set of rotating bars 152 to rotate synchronously. When the cylinder 152 is extended to the longest end, the rotating bar 153 is parallel to the inflow end of the auxiliary conveyor 13, and the packages are guided to the auxiliary conveyor 13. When the cylinder 152 is retracted to the shortest end, the rotating bar 153 is parallel to the inflow end of the auxiliary conveyor 12, and the packages are guided to the auxiliary conveyor 12.

[0035] A turning mechanism is installed on one side of the auxiliary conveyor belt 12, and 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, and the horizontal flipping mechanism 3 is installed on the output end of the reciprocating mechanism 2. The output end of the reciprocating mechanism 2 rises and falls in the vertical direction or approaches or moves away from the auxiliary conveyor belt 12 in the horizontal direction. The horizontal flipping mechanism 3 drives the clamping mechanism 4 to intermittently rotate 180 degrees.

[0036] As a preferred embodiment, the reciprocating mechanism 2 includes a mounting frame 21, the mounting frame 21 is E-shaped, a motor 22 is installed at the bottom end of the mounting frame 21, a screw rod 23 is rotatably installed on the mounting frame 21 along the length direction, the screw rod 23 is fixedly connected to the output end of the mounting frame 21, a movable block 24 is threadedly connected to the screw rod 23, a limiting slider is connected to the movable block 24, a limiting groove is provided on the side wall of the mounting frame 21, and the limiting slider slides in the limiting groove in a limited direction along the vertical direction.

[0037] The motor 22 drives the screw rod 23 to rotate, and the screw rod 23 drives the movable block 24 to rise and fall along the limiting slide groove.

[0038] As a preferred embodiment, the horizontal flipping mechanism 3 includes a motor 2 31 mounted on the movable block 24 , an L-shaped rod 32 is mounted on the output end of the motor 2 31 , a mounting plate 33 is mounted on the end of the L-shaped rod 32 , and the clamping mechanism 3 is mounted on the mounting plate 33 .

[0039] The second motor 31 drives the L-shaped rod 32 to flip 180 degrees, and the L-shaped rod 32 drives the mounting plate 33 to flip 180 degrees, thereby driving the clamping mechanism 3 to flip 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 oblique clamping plate 42 slidably mounted on the mounting plate 33, the oblique clamping plate 42 is parallel to the oblique side of the trapezoidal package, a motor 43 is mounted on the straight clamping plate 41, a screw rod 44 is mounted on the output end of the motor 43, and the screw rod 44 is threadedly connected to the oblique clamping plate 42.

[0041] When the packaging box moves to the turning 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, and then the clamping mechanism 4 clamps the packaging box. Finally, the horizontal flipping mechanism 3 drives the clamping mechanism 4 to flip 180 degrees to the side away from the diverter 15, so that the top and bottom ends of the packaging box are turned; after the turning is completed, the above actions run in reverse, that is, the clamping mechanism 4 releases the packaging box, and then the reciprocating mechanism 2 drives the horizontal flipping mechanism 3 to rise to cancel the limit on the packaging box. The turned packaging box is driven by the auxiliary conveyor belt 12 to continue to move, and 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 unloading device and a second unloading device which are respectively installed on both sides of the auxiliary conveyor belt 1 12 and the auxiliary conveyor belt 2 13. The second unloading device is closer to the main conveyor belt 11 than the first unloading device.

[0043] As a preferred embodiment, the unloading 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 auxiliary conveyor belt 12 in the extension direction of the cylinder 51, and the connecting plate 53 is flush with the top of the auxiliary conveyor belt 12.

[0044] The cylinder 51 pushes the forward packaging box of the auxiliary conveyor belt 12 along the connecting plate 53 to the stacking plate 61 through the push plate 52.

[0045] As a preferred embodiment, the unloading 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 auxiliary conveyor belt 2 13 in the extension direction of the cylinder 2 54 , and the connecting plate 2 56 is flush with the top of the auxiliary conveyor belt 2 13 .

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

[0047] Preferably, limit plates are installed on the edges of the connecting plate 1 53 and the connecting plate 2 56 .

[0048] The limit plate prevents the packaging box from falling over during movement.

[0049] A stacking plate 61 is installed between the auxiliary conveyor belt 12 and the auxiliary conveyor belt 2 13, and the connecting plate 1 53 and the connecting plate 2 56 are both connected to the stacking plate 61 and the connecting plate 1 53 and the connecting plate 2 56 are both flush with the top of the stacking plate 61, and a stacking mechanism 6 is installed on the stacking plate 61 near one end of the main conveyor belt 11.

[0050] Preferably, the stacking mechanism 6 includes a cylinder three 62, and a push plate three 63 is installed on the output end of the cylinder three 62. The extension direction of the cylinder three 62 is consistent with the length direction of the stacking plate 61. When the cylinder three 62 is extended to the longest, the distance between the push plate three 63 and the connecting plate one 53 away from the separator 15 is not less than the sum of the top and bottom ends of the trapezoid of the packaging box. When the cylinder three 62 is extended to the shortest, the push plate three 63 does not exceed the connecting plate two 56 close to the separator 15.

[0051] Preferably, an anti-falling frame 64 is further included, and the anti-falling frame 64 is in sliding contact with the top of the stacking plate 61 and the anti-falling frame 64 is located on the side of the connecting plate 53 away from the turning mechanism.

[0052] The assembly mechanism 5 pushes the forward packaging box on the auxiliary conveyor belt 2 13 onto the stacking plate 61 and pushes the reverse packaging box on the auxiliary conveyor belt 1 12 onto the stacking plate 61. The cylinder 3 62 pushes the forward packaging box to contact the reverse packaging box through the push plate 3 63, so that the oblique edges of the forward packaging box and the reverse packaging box are engaged with each other. The stacking is repeated to complete the stacking. The anti-fall frame 64 supports the packaging box to prevent the packaging box from falling over during the pushing process, causing stacking failure.

[0053] Example 2

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 in sequence along the conveying direction on the other side. The assembly mechanism 5 includes a feeding device 1 and a feeding device 2. The feeding device 1 and the feeding device 2 are installed on the same side of the linear conveyor belt, and the stacking mechanism 6 is installed on the stacking plate 61.

[0055] The turning mechanism and the stacking mechanism 6 are the same as the turning mechanism in the first embodiment.

[0057] The straight conveyor belt is used to transport packaging boxes. The turning mechanism intermittently turns one group of packaging boxes over by 180 degrees for the next group of packaging boxes. The unloading device 1 and the unloading device 2 push the forward and reverse packaging boxes onto the stacking plate 61 in turn, and the stacking mechanism 6 pushes the forward packaging boxes to contact and stack the reverse packaging boxes.
