Description

Technical Field

[0001] The present invention belongs to the field of packaging technology, and specifically relates to a device for stacking a previous packaging box with a subsequent packaging box before packaging, and more particularly to a bio-based packaging box stacking device and a working method thereof. Background Art

[0002] Bio-based packaging boxes refer to packaging containers made from renewable biomass resources (plants, microorganisms, etc.).

[0003] In the related art, the thin-sheet bio-based packaging boxes used for trays of food and electronic products are relatively soft in texture. During production, the bio-based packaging boxes need to be stacked and then packaged to complete the circulation.

[0004] However, collapse often occurs during stacking of thin bio-based packaging boxes.

[0005] Therefore, how to prevent the collapse of thin bio-based packaging boxes during the stacking process is a technical problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0075] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0076] Research has found that in related technologies, bio-based packaging boxes are typically stacked from below to achieve higher stacking heights. However, due to the relatively soft texture of thin bio-based packaging boxes, they are prone to bending during transportation. For example, when transported on a double-sided conveyor belt, the middle of the bio-based packaging box is prone to bending. When transporting bio-based packaging boxes using multiple sets of opposing push rods, the middle is also prone to bending. This makes it impossible to align the bio-based packaging boxes during stacking, resulting in the collapse of the stacked bio-based packaging boxes.

[0077] Based on the above research, the embodiment of the present disclosure provides a bio-based packaging box 300 stacking device and a working method thereof, wherein the bio-based packaging box 300 to be stacked is pushed and flattened by the supporting sub-mechanism 210, so that the bio-based packaging box 300 is aligned with the stacked bio-based packaging boxes 300 when stacked, thereby preventing the bio-based packaging box 300 from collapsing.

[0078] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0079] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0080] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0081] See also Figure 1 and Figure 2 At least one embodiment provides a bio-based packaging box 300 stacking device, including the following structure:

[0082] The conveying mechanism 100 is used to convey the bio-based packaging box 300 .

[0083] See also Figure 3 Specifically, the conveying mechanism 100 includes:

[0084] The conveying assembly 110 is used to convey the bio-based packaging box 300. The conveying belt 111 is used to convey the bio-based packaging box 300.

[0085] The lifting assembly 120 is disposed at the discharge end of the conveying assembly 110 and is used to lift the bio-based packaging box 300 conveyed by the conveying assembly 110 .

[0086] Specifically, the bio-based packaging box 300 is lifted by the lifting plate 121 and the lifting structure 122 .

[0087] The transfer assembly 130 is disposed above the lifting assembly 120 and is used to transfer the bio-based packaging box 300 lifted by the lifting assembly 120 to the stacking mechanism 200 for stacking.

[0088] Specifically, the transfer assembly 130 includes a push plate 131 and a linear drive unit 132.

[0089] The stacking mechanism 200 is used to stack the bio-based packaging boxes 300 conveyed by the conveying mechanism 100 .

[0090] Please continue reading Figure 3 The stacking mechanism 200 includes a supporting sub-mechanism 210 and a supporting sub-mechanism 220. The supporting sub-mechanism 220 is disposed above the supporting sub-mechanism 210 and is used to support the stacked bio-based packaging boxes 300.

[0091] See also Figure 4 and Figure 7 , a control module is configured to control the supporting sub-mechanism 210 to push the bio-based packaging box 300 upward until it abuts against the supporting 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 multiple support rods 211 of the supporting sub-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; and control the supporting sub-mechanism 220 to release the support for the stacked bio-based packaging boxes 300. After stacking is completed, control the supporting sub-mechanism 210 to continue pushing until the second position information transmitted by the second detection sensor 240 is consistent with the second preset information, then stop pushing, control the supporting sub-mechanism 220 to support the stacked bio-based packaging boxes 300, and control the supporting sub-mechanism 210 to reset.

[0092] Specifically, in the first state, the supporting sub-mechanism 210 pushes the bio-based packaging box 300 upwards. Figure 8 As shown, the pushing direction is as Figure 8 In the second state, the top support sub-mechanism 210 continues to push until the bio-based packaging box 300 and the top support sub-mechanism 210 abut against each other, as shown in FIG. Figure 9 In the third state, the top support sub-mechanism 210 continues to push, so that the top support sub-mechanism 210 of the plurality of support rods 211 and the supporting portion 310 at the bottom of the bio-based packaging box 300 abut against and flatten the bio-based packaging box 300, as shown Figure 10 fourth state, the control support sub-mechanism 220 releases the support of the stacked bio-based packaging box 300, and after the stacking is completed, the control top support sub-mechanism 210 continues to push until it passes the support sub-mechanism 220, as shown Figure 11 fifth state, the control support sub-mechanism 220 supports the stacked bio-based packaging box 300, and controls the top support sub-mechanism 210 to reset, as Figure 12 shown.

[0093] The structure of the supporting sub-mechanism 210 is described in detail below. Figure 4The supporting sub-mechanism 210 further includes: a lifting plate 212 and a pushing 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 the two opposite sides of the bio-based packaging box 300; and the supporting directions of the two support rods 211 in each group of support rods 211 are arranged in opposite directions. In this way, when the bio-based packaging box is pushed, the bio-based packaging box 300 is flattened, reducing the degree of bending of the bio-based packaging box 300 when stacked. The support rods 211 are rotatably arranged on the lifting plate 212. In the second state, the support rods 211 are arranged along the two opposite sides of the bio-based packaging box 300. Figure 5 The bio-based packaging box 300 is rotated in the direction of F1, and the bio-based packaging box 300 is flattened 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°.

[0094] See also Figure 4 and Figure 6 The lifting plate 212 is provided with a rotation opening 212a; the support rod 211 is provided with a hinge block 211a; the hinge block 211a is rotatably arranged in the rotation opening 212a via a rotating shaft 211b and a return torsion spring 211c. The return torsion spring 211c is used to reset the support rod 211. At the same time, in order to reduce the fatigue of the return torsion spring 211c, in the fifth state, when the support sub-mechanism 220 is reset, the support rod 211 is pushed along the rotation opening 212a by the support sub-mechanism 220. Figure 5 The return torsion spring 211 c rotates in the direction of F2, causing the return torsion spring 211 c to deform in the opposite direction, thereby improving the fatigue resistance of the return torsion spring 211 c.

[0095] At the same time, the supporting sub-mechanism 220 pushes the support rods 211 to move toward each other. After the elasticity of the return torsion spring 211c decreases or loses its elasticity, the support rods can still complete the return, thereby improving the stability of the stacking device. Figure 4 In an optional embodiment, the supporting sub-mechanism 220 includes: two oppositely arranged supporting side plates 221 and a horizontal cylinder 222 for driving the supporting side plates 221 to move horizontally toward each other; opposite sides of the two supporting side plates 221 are provided with recessed portions 221a adapted to the support rods 211; the control module is further configured to control the supporting sub-mechanism 220 to support the stacked bio-based packaging boxes 300, and push the support rods 211 of the supporting sub-mechanism 220 toward each other through the recessed portions 221a of the supporting side plates 221.

[0096] It should be noted that before the recessed portion 221a of the supporting side plate 221 pushes the strut 211 of the supporting sub-mechanism 220 toward each other, the strut 211 is first lowered by the pushing cylinder 213 so that the top of the strut 211 is separated from the bio-based packaging box 300. At this time, the strut 211 is reset under the action of the reset torsion spring 211c, and the strut 211 of the supporting sub-mechanism 220 is pushed toward each other through the recessed portion 221a of the supporting side plate 221, so that the reset torsion spring 211c is deformed in the opposite direction, thereby improving the fatigue resistance of the reset torsion spring 211c.

[0097] The first detection sensor 230 is embedded in the side wall of the rotation opening 212a of the lifting plate 212 and is used to detect the distance between the support rod 211 and the first detection sensor during rotation, i.e., first position information, and sends it to the control module. When the received first position information is consistent with the first preset position information, the control module indicates that the support rod 211 has rotated to the desired position, and then controls the pushing cylinder 213 to stop pushing. The second detection sensor is embedded in the recess 221a of the supporting side plate 221 and is used to detect the distance that the top surface of the support rod 211 passes over the supporting side plate 221, i.e., second position information, and sends it to the control module. When the received second position information is consistent with the second preset position information, the control module indicates that the support rod 211 has been pushed to the desired position, and then controls the pushing cylinder 213 to stop pushing.

[0098] It should be noted that, in this embodiment, the first detection sensor and the second detection sensor are miniature photoelectric sensors, model E3Z-D62, and the control module controls the first detection sensor and the second detection sensor to start detection in the corresponding process, that is, the first detection sensor only performs distance detection when it is in the third state, and the second detection sensor only performs distance detection when it is in the fourth state.

[0099] Please continue reading Figure 6 The cross-section of the rotating opening 212a is a parallelogram; the control module is further configured to control the supporting sub-mechanism 210 to push the bio-based packaging box 300 upward until it abuts against the supporting sub-mechanism 210, and continue to push so that the multiple support rods 211 of the supporting sub-mechanism 210 abut against the abutting portion 310 at the bottom of the bio-based packaging box 300, and when the bio-based packaging box 300 is flattened, the hinge block 211a of the support rod 211 rotates to abut against the side wall of the rotating opening 212a.

[0100] The sidewalls of the parallelogram-shaped rotation opening 212a limit the support rod 211, preventing it from rotating too much at an angle a when subjected to excessive weight from the stacked bio-based packaging boxes. It should be noted that the return torsion spring has a low elastic modulus, meaning it can undergo significant elastic deformation even under relatively low stress. This prevents scratches on the bio-based packaging boxes when they are flattened.

[0101] 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 rotating opening 212a, the top surface of the support rod 211 rotates to be horizontal.

[0102] See also Figure 2 and Figure 7 The supporting sub-mechanism 220 further includes a supporting main plate 223 and an insertion cylinder 224. The supporting main plate 223 is driven by the insertion cylinder 224 to be inserted between the two supporting side plates 221. After stacking is completed, the supporting main plate 223 is driven to be inserted between the two supporting side plates 221 to support the stacked bio-based packaging boxes 300 and prevent the middle portion of the bio-based packaging boxes 300 from bending downward.

[0103] See also Figure 1 and Figure 2 The embodiment of the present disclosure further provides a bio-based packaging box 300 stacking device, including: a conveying mechanism 100, which is used to convey the bio-based packaging box 300; and a stacking mechanism 200, which is used to stack the bio-based packaging box 300 conveyed by the conveying mechanism 100.

[0104] The stacking mechanism 200 includes: a supporting sub-mechanism 210, which is provided with a lifting plate 212 and a support rod 211 rotatably provided on the lifting plate 212; a supporting sub-mechanism 220, which is provided above the supporting sub-mechanism 210 and is used to support the stacked bio-based packaging boxes 300; a control module, which is configured to control the supporting sub-mechanism 210 to push the bio-based packaging box 300 upward until it contacts the supporting sub-mechanism 210, and continue to push until the first position information and the first preset information transmitted by the first detection sensor 230 are received. After the second position information transmitted by the second detection sensor 240 is consistent with the second preset information, the pushing is stopped, the support rod 211 is rotated outward, and the bio-based packaging box 300 is flattened; and the supporting sub-mechanism 220 is controlled to release the support for the stacked bio-based packaging boxes 300. After the stacking is completed, the supporting sub-mechanism 210 is controlled to continue pushing until the second position information transmitted by the second detection sensor 240 is consistent with the second preset information, the pushing is stopped, the supporting sub-mechanism 220 is controlled to support the stacked bio-based packaging boxes 300, and at the same time, the supporting rod 211 is pushed to rotate inward, and the supporting sub-mechanism 210 is controlled to reset.

[0105] The transported bio-based packaging boxes 300 are stacked by providing a supporting sub-mechanism 210 and a supporting sub-mechanism 220. During stacking, the supporting sub-mechanism 220 supports the already stacked bio-based packaging boxes 300, and the supporting sub-mechanism 210 pushes and flattens the bio-based packaging boxes 300 to be stacked. This prevents 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.

[0106] See also Figure 14 At least one embodiment further provides a working method for the bio-based packaging box 300 stacking device as described above, the working method comprising:

[0107] Step S110 , transporting the bio-based packaging box 300 through the transport mechanism 100 ;

[0108] Step S120 , the control module controls the supporting sub-mechanism 210 to push the bio-based packaging box 300 upward until it abuts against the supporting sub-mechanism 210 ;

[0109] Step S130 : The control module controls the supporting sub-mechanism to continue to push, so that the multiple supporting rods 211 of the supporting sub-mechanism 210 abut against the supporting portion 310 at the bottom of the bio-based packaging box 300 , and the bio-based packaging box 300 is flattened.

[0110] Step S140 : The control module controls the supporting sub-mechanism 220 to release the support for the stacked bio-based packaging boxes 300 , thereby completing the stacking.

[0111] Step S150: The control module controls the supporting sub-mechanism 210 to continue pushing until the bio-based packaging boxes 300 pass through the supporting sub-mechanism 220, and controls the supporting sub-mechanism 220 to support the stacked bio-based packaging boxes 300;

[0112] In step S160 , the control module controls the supporting sub-mechanism 220 to reset.

[0113] In summary, the present invention provides a device and operating method for stacking bio-based packaging boxes 300. The device stacks bio-based packaging boxes 300 by providing a supporting sub-mechanism 210 and a supporting sub-mechanism 220 to stack conveyed bio-based packaging boxes 300. During stacking, the supporting sub-mechanism 220 supports the already stacked bio-based packaging boxes 300, and the supporting sub-mechanism 210 pushes and flattens the bio-based packaging boxes 300 to be stacked. This prevents 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.

The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
