In order to ensure the convenience of product collection and packaging, the existing automatic assembly line increases the cover structure according to the situation to collect the products after transfer printing.

[0005] With the development of the transfer printing industry, the types of packaging boxes for transfer printing are gradually increasing. Especially when the conjoined packaging box is transferred, the conjoined packaging box has a cover body, a folding edge and a box body. Before feeding, the conjoined packaging box is stored by stacking. The stacking method of the conjoined packaging box is that a plurality of cover bodies and a plurality of box bodies are stacked together.

[0006] Among them, due to the fact that the depth of the box body is much larger than the depth of the cover body, it is difficult to stack the box body with large depth by inertia or gravity. In order to stack the box bodies together, the box body needs to be embedded into the box body of the adjacent conjoined packaging box by external force, which increases the step of mutual extrusion and stacking during storage, increases the storage time of the conjoined packaging box, and is limited by the storage speed, which makes it difficult to improve the production efficiency.

[0046] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0047] Referring to FIGS. 1-3, in some embodiments of the present application, the present application provides a connected packaging box storage device, comprising: a material receiving assembly 1, a transmission assembly 2 and a pushing assembly 3, the material receiving assembly 1 and the pushing assembly 3 are arranged at both ends of the transmission assembly 2, wherein the material receiving assembly 1 is used to transmit the connected packaging boxes 41 to the transmission assembly 2 one by one, and a certain number of connected packaging boxes 41 are sent to the vicinity of the pushing assembly 3. The pushing assembly 3 pushes a certain number of connected packaging boxes 41 to a fixed position for storage. In order to facilitate storage, a certain number of connected packaging boxes 41 need to be stacked to form a packaging box group. The stacking method is to stack the cover and the box body of the connected packaging box 41 respectively.

[0048] In the present scheme, the receiving assembly 1 can also realize stacking of the adjacent connected packaging boxes 41 during the process of conveying the connected packaging boxes 41 one by one. The conveying assembly 2 comprises a pallet unit 23, and the receiving assembly 1 is arranged at one side of the upstream end of the pallet unit 23, and the connected packaging boxes 41 are stacked close to the upstream end of the pallet unit 23.

[0049] Specifically, as shown in FIGS. 4 and 5, the receiving assembly 1 comprises a turnover unit 11, a guide rod unit 12, and a driving unit 14. The turnover unit 11 has a circulating line body 111, and the circulating line body 111 is provided with bottom supporting plates 112 at intervals. The connected packaging boxes 41 are contained between two adjacent bottom supporting plates 112. The driving unit 14 is used to drive the circulating line body 111, so that the connected packaging boxes 41 between the bottom supporting plates 112 are conveyed one by one towards the conveying assembly 2. For example, the bottom supporting plates 112 move along a first straight line direction towards the conveying assembly 2.

[0050] The guide rod unit 12 comprises a guide rod 121. As shown in FIGS. 6 and 7, the bottom supporting plate 112 has an avoiding groove 1121 for receiving the guide rod 121. The bottom supporting plate 112 has a bottom portion 1122 and a top portion 1123 as opposite ends. The bottom portion 1122 is installed on the circulating line body 111, and the top portion 1123 is arranged away from the circulating line body 111. The avoiding groove 1121 penetrates through the bottom supporting plate 112 and extends to the top portion 1123. The guide rod 121 is located in the avoiding groove 1121.

[0051] The guide rod 121 extends towards the conveying assembly 2. The extension direction of the guide rod 121 is arranged at an angle with the feeding direction of the circulating line body 111 (i.e. the first straight line direction). Along the extension direction of the guide rod 121, the distance between the guide rod 121 and the circulating line body 111 gradually increases. At least the guide rod 121 close to one side of the pallet unit 23 is flush with the top portion 1123 of the bottom supporting plate 112. The connected packaging boxes 41 between two bottom supporting plates 112 move along with the circulating line body 111, and are also limited by the guide rod 121. Therefore, the connected packaging boxes 41 move along the extension direction of the guide rod 121, and the position of the connected packaging boxes 41 relative to the bottom supporting plate 112 carrying itself changes.

[0052] In the present scheme, the driving unit 14 drives the circulating line body 111, so that the bottom supporting plate 112 moves relative to the guide rod 121, and along the extension direction of the guide rod 121, the distance between the guide rod 121 and the circulating line body 111 gradually increases. During the operation of the circulating line body 111, the closer the bottom supporting plate 112 is to the pallet unit 23, the closer the guide rod 121 is to the top portion 1123 of the bottom supporting plate 112. That is, the position of the avoiding groove 1121 on each bottom supporting plate 112 is different. In order to avoid interference between the guide rod 121 and the moving bottom supporting plate 112, the avoiding groove 1121 is designed to penetrate through the bottom supporting plate 112 and extend to the top portion 1123.

[0053] Based on the above-mentioned one-piece packaging box storage device, during the circulation of the one-piece packaging box 41 in the circulation line body 111, the one-piece packaging box 41 is always located above the flow guide rod 121. During the process of the one-piece packaging box 41 gradually approaching the transmission assembly 2, the one-piece packaging box 41 gradually increases from the top 1123 of the bottom support plate 112, and finally realizes the complete separation of the one-piece packaging box 41 from the bottom support plate 112. The one-piece packaging box 41 located upstream is still limited by the bottom support plate 112 when it is not separated from the bottom support plate 112, and the one-piece packaging box 41 is continuously pushed forward along the extension direction of the flow guide rod 121 by the bottom support plate 112. On the other hand, the one-piece packaging box 41 completely separated from the bottom support plate 112 is not subjected to the thrust force of the bottom support plate 112, which makes it difficult to continue to move forward without external force. Because the one-piece packaging box 41 that has not been separated from the bottom support plate 112 continuously advances, and the one-piece packaging box 41 that has been completely separated from the bottom support plate 112 is stationary, the one-piece packaging box 41 upstream pushes the one-piece packaging box 41 separated from the bottom support plate 112 to move forward, and at the same time of advancing the one-piece packaging box 41 as a whole, the frictional resistance generated when the one-piece packaging box 41 separated from the bottom support plate 112 advances, will cause the interval between the two one-piece packaging boxes 41 separated from the bottom support plate 112 to be reduced, thereby realizing the stacking of the cover body and the box body respectively. Compared with the existing scheme of applying extrusion force to the one-piece packaging box to stack two one-piece packaging boxes 41 together, the automatic stacking in the circulation process is realized in the present application, the process of extruding and stacking by external force is reduced, and the automatic extrusion and stacking of the one-piece packaging box 41 is realized by the interaction of the thrust force and the frictional force during the advancement of the one-piece packaging box 41, thereby improving the production efficiency.

[0054] In the above-mentioned scheme, the one-piece packaging box 41 located upstream is the one-piece packaging box 41 close to the end of the circulation line body 111 away from the transmission assembly 2, and the one-piece packaging box 41 located upstream is located between the two bottom support plates 112 and continuously advances under the action of the bottom support plate 112. The advancement is the transmission direction of the one-piece packaging box 41, specifically the direction of the circulation line body 111 towards the transmission assembly 2.

[0055] Further, the circulation line body 111 includes a driving pulley 1111, a driven pulley 1112 and a transmission chain 1113. In the present scheme, the driving pulley 1111 is in transmission connection with the driving unit 14, the driving pulley 1111 and the driven pulley 1112 are in transmission connection through the transmission chain 1113, and the bottom support plate 112 is installed on the transmission chain 1113.

[0056] Specifically, the driving wheel 1111 and the driven wheel 1112 are connected by the transmission chain 1113, the transmission chain 1113 is supported by the driving wheel 1111 and the driven wheel 1112, so that a part of the transmission chain 1113 is arranged in a straight line, and the downstream end of the straight line of the transmission chain 1113 is arranged close to the transmission assembly 2 along the movement direction of the transmission chain 1113. Specifically, the transmission chain 1113 is a silent chain, and the transmission chain 1113 is engaged with the driving wheel 1111 and the driven wheel 1112 to drive, and the transmission chain 1113 is a silent chain to reduce the noise generated by the driving wheel 1111, the driven wheel 1112 and the transmission chain 1113 during operation. The bottom supporting plates 112 are uniformly arranged on the surface opposite to the tooth part of the transmission chain 1113. The bottom 1122 of the bottom supporting plate 112 is fixedly connected to the transmission chain 1113, so that the bottom supporting plate 112 is arranged vertically at an angle of 90° or approximately 90° with the transmission chain 1113.

[0057] The interval between the adjacent two bottom supporting plates 112 is greater than the depth of the box body of the connected packaging box 41 and is not greater than the sum of the depths of the box body and the cover body of the connected packaging box 41, so that the box body and the cover body of the connected packaging box 41 are limited by the adjacent two bottom supporting plates 112, and the effect of stacking is affected.

[0058] In the present scheme, the extension direction of the guide rod 121 is arranged at an angle with the straight line on the transmission chain 1113, and the guide rod 121 is located above the straight line. Under the driving of the driving unit 14, the bottom supporting plates 112 on the part (i.e. the straight line) of the transmission chain 1113 move in the feeding direction (i.e. the first straight line direction).

[0059] Further, the guide rod 121 comprises an initial segment 1211, an arc segment 1212 and a guide-out segment 1214, which are connected in sequence. The arc segment 1212 is arranged in parallel with the transmission chain 1113; and the extension direction of the guide-out segment 1214 is arranged at an angle with the feeding direction.

[0060] Specifically, the arc segment 1212 is arranged in parallel with the transmission chain 1113 corresponding to the driven wheel 1112, and the arc segment 1212 is arranged concentrically with the driven wheel 1112; and the interval distance between the arc segment 1212 and the transmission chain 1113 corresponding to the driven wheel 1112 is consistent. The connected packaging box 41 is fed into the corresponding two bottom supporting plates 112 from the side of the circulation line body 111 close to the driven wheel 1112. The guide rod 121 covers the transmission chain 1113 through which the connected packaging box 41 enters and flows out of the circulation line body 111.

[0061] The extension direction of the initial section 1211 is perpendicular to the extension direction of the leading-out section 1214. The guide rod unit 12 further comprises a mounting seat 122, the initial section 1211 is arranged through the mounting seat 122, and the mounting seat 122 is mounted on the support of the circulating line body 111, so as to fix the position of the guide rod 121.

[0062] More specifically, the transition section 1213 is arranged between the arc section 1212 and the leading-out section 1214, and the transition section 1213 extends in an arc shape. In order to stably transfer the connected packaging box 41 from the arc section 1212 to the leading-out section 1214. The transition section 1213 is arranged between the arc section 1212 and the leading-out section 1214, so that the arc section 1212 and the leading-out section 1214 are smoothly transitioned through the transition section 1213. For example, the two ends of the transition section 1213 are tangentially arranged with the arc section 1212 and the leading-out section 1214.

[0063] In some embodiments of the present application, as shown in FIGS. 2 and 7, the material receiving assembly 11 further comprises a guide unit 13 and a side plate 15, wherein the guide unit 13 is at least located above the bottom supporting plate 112 corresponding to the straight section, and the guide unit 13 is arranged in parallel with the extension direction of the leading-out section 1214, so as to limit the position of the connected packaging box 41 in the vertical direction, and the side plate 15 is arranged on both sides of the circulating line body 111, so that the side plate 15 is located on both sides of the bottom supporting plate 112 to limit the position of the connected packaging box 41 in the horizontal direction.

[0064] Preferably, the guide unit 13 is located above the circulating line body 111, and the guide unit 13 comprises an arc-shaped guide section and a straight guide section, the arc-shaped guide section corresponds to the position of the transmission chain 1113 where the driven roller 1112 is located, and the straight guide section corresponds to the position of the transmission chain 1113 where the straight section is located, so that after the connected packaging box 41 is fed into the circulating line body 111, the guide unit 13 limits the position of the connected packaging box 41 in the vertical direction, and prevents the connected packaging box 41 from deviating in the vertical direction.

[0065] At the same time, as shown in FIGS. 1 and 4, the upper side of the material plate unit 23 is provided with a stacking station 231 and a pushing-out station 232, and the stacking station 231 is arranged close to the upstream end of the material plate unit 23. The transmission assembly 2 further comprises a counting unit 21 and a material distributing unit 22, the counting unit 21 is arranged on the stacking station 231, and the material distributing unit 22 is located between the stacking station 231 and the pushing-out station 232. The side plate 15 extends into the stacking station 231, and the counting unit 21 is mounted on the side plate 15. The material distributing unit 22 can also be mounted on the side plate 15. It can be understood that the guide unit 13 also extends to the stacking station 231, and the counting unit 21 and / or the material distributing unit 22 are mounted on the guide unit 13.

[0066] In the scheme, the counting unit 21 is electrically connected with the separating unit 22. During the movement of the connected packaging boxes 41 on the material plate unit 23, the connected packaging boxes 41 pass through the counting unit 21 one by one, and the counting unit 21 counts the number of the connected packaging boxes 41. When the counting unit 21 counts a certain number of connected packaging boxes 41, the separating unit 22 separates the connected packaging boxes 41 in the stack, and sends the separated certain number of connected packaging boxes 41 to the push-out station 232 for storage. The counting unit 21 can be an electronic counter or a mechanical counter. The electronic counter can be an infrared counter. When the connected packaging boxes 41 pass through the infrared rays, the connected packaging boxes 41 are counted once for each time of blocking the infrared rays.

[0067] Further, the counting unit 21 can also be a mechanical counter. Specifically, the counting unit 21 includes a fixed plate 211, an encoder 212, a rotating shaft 213, and a gear 214. The encoder 212 is mounted on the fixed plate 211. In the scheme, the fixed plate 211 is fixedly connected to the side plate 15, and the fixed plate 211 extends from the side plate 15. The encoder 212 is mounted on the part of the fixed plate 211 extending from the side plate 15. One end of the rotating shaft 213 is connected to the encoder 212, and the gear 214 is connected to the other end of the rotating shaft 213. The teeth of the gear 214 are embedded between the skirts of two connected packaging boxes 41 in the stack. When the connected packaging boxes 41 in the stack move towards the push-out station 232, the connected packaging boxes 41 drive the gear 214 to rotate, and the gear 214 drives the rotating shaft 213 to rotate through a certain angle, which is counted as one connected packaging box 41.

[0068] In the above embodiment, while the skirts of the connected packaging boxes 41 drive the gear 214 to rotate to realize counting, the connected packaging boxes 41 are subjected to the rotating resistance generated by the rotation of the rotating shaft 213 relative to the encoder 212, and the friction generated by the movement of the connected packaging boxes 41 on the material plate unit 23 and the resistance generated by the rotation of the counting unit 21. The two acting forces are arranged opposite to the pushing force of the bottom support plate 112 on the connected packaging boxes 41, and the connected packaging boxes 41 in the stack on the stacking station 231 are extruded to realize stacking of the connected packaging boxes 41, so as to improve the stacking effect between the connected packaging boxes 41.

[0069] Further, the material separating unit 22 comprises a screw rod and a cylinder, the screw rod drives the cylinder to move along the extension direction of the guide rod 121, and the power output end of the cylinder can extend into the space between the two stacks of the connected packaging boxes 41. The counting unit 21 controls the material separating unit 22 to work, and when the counting unit 21 counts a certain number of connected packaging boxes 41, the material separating unit 22 separates the two stacks of the connected packaging boxes 41 and drives the separated connected packaging boxes 41 to move to the pushing station 232.
