Detailed implementation manners

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0025] Through research, it is found that in the related art, in order to stack biobased packaging boxes higher, the biobased packaging boxes are generally stacked in a manner of inserting from below. However, due to the relatively soft texture of the sheet-shaped biobased packaging boxes, they are prone to bending during transportation. For example, when using a bilateral conveyor belt for transportation, the middle part of the biobased packaging box is prone to bending. When using multiple sets of push rods arranged oppositely to transport the biobased packaging boxes, the middle part is also prone to bending, resulting in the inability to align the biobased packaging boxes during stacking, and thus the stacked biobased packaging boxes collapse.

[0026] Based on the above research, the embodiments of the present disclosure provide a stacking device for biobased packaging boxes 300 and its working method. The to-be-stacked biobased packaging boxes 300 are pushed and flattened by the top support mechanism 210, so that when the biobased packaging boxes 300 are stacked, they are aligned with the stacked biobased packaging boxes 300, avoiding the collapse of the biobased packaging boxes 300.

[0027] Regarding the defects existing in the above solutions, they are all the results obtained by the inventor through practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article for the above problems should be the contributions made by the inventor to the present disclosure during the process of the present disclosure.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] Please refer to Figure 1 and Figure 2 , at least one embodiment provides a stacking device for biobased packaging boxes 300, including the following structures: A conveying mechanism 100, which is used to convey the biobased packaging boxes 300.

[0031] Please refer to Figure 3 , specifically, the conveying mechanism 100 includes: A conveying assembly 110 for conveying the biobased packaging box 300. A conveyor belt 111 is used to convey the biobased packaging box 300.

[0032] A lifting assembly 120 is arranged at the discharge end of the conveying assembly 110 and is used for lifting the biobased packaging box 300 conveyed by the conveying assembly 110.

[0033] Specifically, the lifting of the biobased packaging box 300 is completed by a lifting plate 121 and a lifting structure 122.

[0034] A transfer assembly 130 is arranged above the lifting assembly 120 and is used for transferring the biobased packaging box 300 lifted by the lifting assembly 120 to the stacking mechanism 200 for stacking.

[0035] Specifically, the transfer assembly 130 includes a push plate 131 and a linear drive part 132. Through the linear drive part 132 A stacking mechanism 200 is used for stacking the biobased packaging boxes 300 conveyed by the conveying mechanism 100.

[0036] Please continue to refer to Figure 3 , wherein the stacking mechanism 200 includes a top support sub-mechanism 210 and a support sub-mechanism 220. Among them, the support sub-mechanism 220 is arranged above the top support sub-mechanism 210 and is used for supporting the stacked biobased packaging boxes 300.

[0037] Please refer to Figure 4 and Figure 7 , a control module configured to control the top support sub-mechanism 210 to push the biobased packaging box 300 upward until it abuts against the top support sub-mechanism 210, and continue to push until the first position information transmitted by the first detection sensor 230 is consistent with the first preset information, then stop pushing, so that the plurality of support rods 211 of the top support sub-mechanism 210 abut against the abutting part 310 at the bottom of the biobased packaging box 300, and flatten the biobased packaging box 300; and, control the support sub-mechanism 220 to release the support for the stacked biobased packaging boxes 300. After stacking is completed, control the top support sub-mechanism 210 to continue to push until the second position information transmitted by the second detection sensor 240 is consistent with the second preset information, then stop pushing, control the support sub-mechanism 220 to support the stacked biobased packaging boxes 300, and control the top support sub-mechanism 210 to reset.

[0038] Specifically, in the first state, the top support sub-mechanism 210 pushes the biobased packaging box 300 upward, as Figure 8 shown, the pushing direction is as Figure 8As shown in F in the figure; in the second state, the top support mechanism 210 continues to push until the bio-based packaging box 300 abuts against the top support mechanism 210, as Figure 9 shown; in the third state, the top support mechanism 210 continues to push, so that the multiple support rods 211 of the top support mechanism 210 abut against the abutting portion 310 at the bottom of the bio-based packaging box 300, and flatten the bio-based packaging box 300, as Figure 10 shown; in the fourth state, control the support mechanism 220 to release the support for the stacked bio-based packaging boxes 300. After stacking is completed, control the top support mechanism 210 to continue to push until it crosses the support mechanism 220, as Figure 11 shown; in the fifth state, control the support mechanism 220 to support the stacked bio-based packaging boxes 300, and control the top support mechanism 210 to reset, as Figure 12 shown.

[0039] The structure of the top support mechanism 210 will be described in detail below. Please refer to Figure 4 , the top support mechanism 210 further includes: a lifting plate 212 and a top push cylinder 213; the support rods 211 are rotatably arranged on the top surface of the lifting plate 212; the support rods 211 are arranged in pairs, and there are two groups of support rods 211 in total; the two groups of support rods 211 are respectively arranged along two opposite sides of the bio-based packaging box 300; and, the opening directions of the two support rods 211 in each group of support rods 211 are opposite to each other. Thus, when pushing the bio-based packaging box, the bio-based packaging box 300 is flattened, and the bending degree of the bio-based packaging box 300 during stacking is reduced. The support rods 211 are rotatably arranged on the lifting plate 212. In the second state, the support rods 211 rotate along the Figure 5 direction of F1 in the figure, and flatten the bio-based packaging box 300 during the rotation process to prevent the bio-based packaging box 300 from bending. The rotation angle is a, and the range of a is 5° - 10°.

[0040] Please refer to Figure 4 and Figure 6 , the lifting plate 212 is provided with a rotation opening 212a; a hinge block 211a is sleeved on the support rod 211; the hinge block 211a is rotatably arranged in the rotation opening 212a through a rotating shaft 211b and a return torsion spring 211c. The return of the support rod 211 is completed through the return torsion spring 211c. At the same time, in order to reduce the fatigue of the return torsion spring 211c, when the support mechanism 220 resets in the fifth state, the support mechanism 220 is used to push the support rod 211 to rotate along the Figure 5 direction of F2 in the figure, so that the return torsion spring 211c undergoes a reverse deformation, thereby improving the anti-fatigue ability of the return torsion spring 211c.

[0041] Meanwhile, the support sub-mechanism 220 is used to push the support rods 211 to move towards each other. After the elastic force of the reset torsion spring 211c decreases or loses its elasticity, the support rods can still complete the reset, thereby improving the stability of the stacking device. Please refer to Figure 4 , in an alternative embodiment, the support sub-mechanism 220 includes: two oppositely arranged support side plates 221 and a horizontal air cylinder 222 for driving the support side plates 221 to move horizontally towards each other; recesses 221a adapted to the support rods 211 are formed on the opposite sides of the two support side plates 221; the control module is further configured to control the support sub-mechanism 220 to support the stacked bio-based packaging boxes 300, and push the support rods 211 of the support sub-mechanism 220 towards each other through the recesses 221a of the support side plates 221.

[0042] It should be noted that before the recesses 221a of the support side plates 221 push the support rods 211 of the support sub-mechanism 220 towards each other, the support rods 211 are first lowered by the push cylinder 213 so that the tops of the support rods 211 are separated from the bio-based packaging boxes 300. At this time, the support rods 211 are reset under the action of the reset torsion spring 211c, and the recesses 221a of the support side plates 221 push the support rods 211 of the support sub-mechanism 220 towards each other, so that the reset torsion spring 211c undergoes a reverse deformation, thereby improving the anti-fatigue ability of the reset torsion spring 211c.

[0043] Among them, the first detection sensor 230 is embedded on the side wall of the rotation port 212a of the lifting plate 212, and is used to detect the distance between the support rod 211 during rotation and the first detection sensor, that is, the first position information, and send it to the control module. When the first position information received by the control module is consistent with the first preset position information, it indicates that at this time, the support rod 211 has rotated to the required position, and then the control module controls the push cylinder 213 to stop pushing. The second detection sensor is embedded on the recess 221a of the support side plate 221, and is used to detect the distance that the top surface of the support rod 211 passes over the support side plate 221, that is, the second position information, and send it to the control module. When the second position information received by the control module is consistent with the second preset position information, it indicates that at this time, the support rod 211 has been pushed to the required position, and then the control module controls the push cylinder 213 to stop pushing.

[0044] It should be noted that in this embodiment, the first detection sensor and the second detection sensor are miniature photoelectric sensors, with the model number E3Z-D62. The control module controls the first detection sensor and the second detection sensor to start detection in the corresponding processes, that is, the first detection sensor only performs distance detection in the third state, and the second detection sensor only performs distance detection in the fourth state.

[0045] Please continue to refer to Figure 6, the cross-section of the rotation port 212a is a parallelogram; the control module is further configured to control the top support mechanism 210 to push the biobased packaging box 300 upward until it abuts against the top support mechanism 210, and continue to push, so that the plurality of support rods 211 of the top support mechanism 210 abut against the abutting portion 310 at the bottom of the biobased packaging box 300, and when the biobased packaging box 300 is flattened, the hinge block 211a of the support rod 211 rotates to abut against the side wall of the rotation port 212a.

[0046] The side wall of the parallelogram-shaped rotation port 212a is used to limit the support rod 211, so as to prevent the rotation angle α of the support rod 211 from being too large when the gravity of the stacked biobased packaging boxes on the support rod 211 is too large. It should be noted that the elastic modulus of the return torsion spring is small, that is, a large elastic deformation can occur under a small stress, so that the biobased packaging box will not be scratched when it is flattened.

[0047] Wherein, the top surface of the support rod 211 is an inclined surface; and when the hinge block 211a of the support rod 211 rotates to abut against the side wall of the rotation port 212a, the top surface of the support rod 211 rotates to be horizontal.

[0048] Please refer to Figure 2 and Figure 7 , the support mechanism 220 further includes: a support main board 223 and an insertion cylinder 224; the support main board 223 is used to be inserted between the two support side boards 221 under the drive of the insertion cylinder 224. After stacking is completed, the support main board 223 is driven to be inserted between the two support side boards 221 to support the stacked biobased packaging boxes 300, so as to prevent the middle part of the biobased packaging boxes 300 from bending downward.

[0049] Please refer to Figure 1 and Figure 2 , the present disclosure embodiment further provides a biobased packaging box stacking device, including: a conveying mechanism 100, which is used to convey the biobased packaging box 300; a stacking mechanism 200, which is used to stack the biobased packaging boxes 300 conveyed by the conveying mechanism 100.

[0050] Among them, the stacking mechanism 200 includes: a top support sub-mechanism 210, which is provided with a lifting plate 212 and a support rod 211 rotatably arranged on the lifting plate 212; a support sub-mechanism 220, which is arranged above the top support sub-mechanism 210 and is used to support the stacked bio-based packaging boxes 300; a control module, which is configured to control the top support sub-mechanism 210 to push the bio-based packaging box 300 upward until it abuts against the top support sub-mechanism 210, and continue to push until the first position information transmitted by the first detection sensor 230 is consistent with the first preset information, then stop pushing, and make the support rod 211 rotate outwards to flatten the bio-based packaging box 300; and, control the support sub-mechanism 220 to release the support for the stacked bio-based packaging boxes 300. After stacking is completed, control the top support sub-mechanism 210 to continue to push until the second position information transmitted by the second detection sensor 240 is consistent with the second preset information, then stop pushing, control the support sub-mechanism 220 to support the stacked bio-based packaging boxes 300, and at the same time, push the support rod 211 to rotate inwards and control the top support sub-mechanism 210 to reset.

[0051] By providing the top support sub-mechanism 210 and the support sub-mechanism 220, the conveyed bio-based packaging boxes 300 are stacked. During stacking, the support sub-mechanism 220 supports the stacked bio-based packaging boxes 300, and then the top support sub-mechanism 210 pushes and flattens the bio-based packaging box 300 to be stacked, so as to prevent the bent and deformed bio-based packaging box 300 from entering the bottom of the stacked bio-based packaging boxes 300, thereby reducing the possibility of the bio-based packaging boxes 300 collapsing during stacking.

[0052] Please refer to Figure 14 , at least one embodiment further provides a working method applied to the bio-based packaging box 300 stacking device as described above. The working method includes: Step S110, conveying the bio-based packaging box 300 through the conveying mechanism 100; Step S120, the control module controls the top support sub-mechanism 210 to push the bio-based packaging box 300 upward until it abuts against the top support sub-mechanism 210; Step S130, the control module controls the top support sub-mechanism to continue to push, so that the plurality of support rods 211 of the top support sub-mechanism 210 abut against the abutting part 310 at the bottom of the bio-based packaging box 300 and flatten the bio-based packaging box 300; Step S140, the control module controls the support sub-mechanism 220 to release the support for the stacked bio-based packaging boxes 300 to complete the stacking; Step S150: The control module controls the top support mechanism 210 to continue pushing until it passes over the support mechanism 220, and then controls the support mechanism 220 to support the stacked bio-based packaging boxes 300. Step S160: The control module controls the support mechanism 220 to reset.

[0053] In summary, the present invention provides a stacking device and a working method for bio-based packaging boxes 300. The stacking device for bio-based packaging boxes 300 stacks the conveyed bio-based packaging boxes 300 by providing a top support mechanism 210 and a support mechanism 220. During stacking, the support mechanism 220 supports the stacked bio-based packaging boxes 300, and then the top support mechanism 210 pushes and flattens the bio-based packaging boxes 300 to be stacked, so as to prevent the bent and deformed bio-based packaging boxes 300 from entering the bottom of the stacked bio-based packaging boxes 300, thereby reducing the possibility of the bio-based packaging boxes 300 collapsing during stacking.
