[0040] In the field of packaging technology, after production, sheets need to be packaged, and generally, they are packaged in a box. In the process of feeding materials into the box, the opening of the box is relatively small in its natural state, while the height of the sheet group to be packaged in its natural state is almost the same as the opening of the box. This results in a low success rate for material assembly, affecting work efficiency. In addition, for sheets with irregular surfaces, the feeding method in traditional technology may also cause wear of the sheets and damage to the device, reducing production efficiency. Therefore, providing a feeding method and feeding structure that can improve the success rate of assembly has become a difficult problem that technicians in this field are eager to solve.

[0041] In view of this, the present invention provides a method for feeding materials into a box, wherein: Figures 1 to 2 This is a schematic diagram of the steps of an embodiment of the feeding method provided by the present invention. The present invention also provides a feeding structure for feeding into the box. Figures 3 to 5 This is a structural schematic diagram of an embodiment of the feeding box structure provided by the present invention.

[0042] See also Figure 1The present invention provides a method for feeding materials into a box, which specifically includes the following steps:

[0043] S10, providing a bell mouth at the end of the expanding device, wherein the end of the bell mouth extends along the pushing direction to form a feeding end;

[0044] It should be noted that the box body is a general packaging box body of a rectangular parallelepiped or a cube, which is mainly used to store packaging sheets. The sheets can be understood as sheet materials with regular shapes, such as plastic sheets, paper, instructions, etc. The expanding device actively opens the opening of the box body to form a feeding port to facilitate the assembly of stacked sheets. The expanding of the box body by the expanding device can be understood as fixing one side of the box body opening, and the expanding device controls the other opposite side to move in the opposite direction. It can also be that the expanding device simultaneously controls the two opposite sides of the box body to move in opposite directions. The expanding process of the box body can solve the problem of low assembly success rate caused by the fact that the height of the box body opening and the stacked sheets are almost the same in traditional technology, and significantly improves the assembly success rate.

[0045] S20, pushing the box body from a distance from the feeding end, with the opening of the box body facing the feeding end, and inserting the feeding end into the inner cavity of the box body;

[0046] S30, limiting the tail of the box body with a limiting structure, and pushing the stacked sheets in from the front of the opening of the box body along the bell mouth.

[0047] It should be noted that the stacked sheets are opposite to the feeding port. After the box body is expanded, the pushing mechanism pushes the sorted stacked sheets into the box body through the feeding port to complete the feeding process.

[0048] Further, see Figure 2 , after “pushing the box body from a distance from the feeding end, with the opening of the box body facing the feeding end, and inserting the feeding end into the inner cavity of the box body”, the following steps are also included:

[0049] S100: Adjust the distance between the springs of the bell mouth to open the opening of the box body.

[0050] Since both the sheet and the construction structure exert forces on the box during the process of feeding materials into the box, in order to prevent the box from moving during the assembly process, causing damage to the box or reducing the success rate of assembly, the box needs to be limited after entering the assembly station. Generally, the box will be limited in the pushing direction to prevent it from moving. The pushing direction here can be understood as the feeding direction of the sheet into the box, which can be a limit on the tail of the box.

[0051] For further information, see Figure 2After “limiting the tail of the box body with a limiting structure and pushing the stacked pieces into the box body from the front of the opening along the bell mouth”, the following steps are also included:

[0052] S200 , a channel with a bottom slot is preset at the opening of the box body, stacked sheets are laid on the channel, and a pushing block pushes the stacked sheets along the bottom slot.

[0053] Boxes waiting for packaging are arranged in an orderly manner at the waiting station. Once the boxes at the assembly station are packed, they are transported to the assembly station for the next round of packaging. By zoning the waiting and assembly stations, we can ensure orderly production, speed up production rhythm, and improve production efficiency.

[0054] The present invention expands the opening of the box body located at the assembly station through an expansion device to form a feed port, and the pushing mechanism pushes the stacked sheets into the box body through the feed port along the pushing direction, so that the opening of the material box is expanded, which significantly improves the success rate of feeding into the box, reduces the risk of sheet wear, and improves the production quality of the product.

[0055] The following describes the feeding inlet method in conjunction with a specific device. This embodiment provides a feeding box structure 1000, including a mounting seat 100, an expansion device 200 and a pushing mechanism 300. In the drawings of this specification, Figure 3 A schematic diagram of the three-dimensional structure of an embodiment of the material feeding into the box structure 1000 provided by the present invention; Figure 4 for Figure 1 Top view in ; Figure 5 for Figure 1 Schematic diagram of the three-dimensional structure when the middle movable plate 221 and the box body 500 are assembled.

[0056] As mentioned above, the stacked sheets can be plastic sheets, instruction manuals, etc. In traditional technology, the assembly success rate of stacked sheets in the box is low. Due to the unstable assembly effect, the sheets may be worn during the boxing process, affecting production quality. In addition, during the assembly of sheets such as instruction manuals, the assembly effect is poor due to the presence of accessories such as staples on the instructions. The staples on the instructions are easily damaged and lost, which not only affects the quality of the materials but also may cause damage to the machine. Please refer to Figure 3In the technical solution provided by the present invention, the feeding-into-box structure 1000 includes a mounting seat 100, an expanding device 200, and a pushing mechanism 300. The mounting seat 100 includes a mounting area 110 for mounting the box body 500; the expanding device 200 includes at least one expanding structure 210 movably connected to the mounting seat 100, and an expanding drive assembly 220 provided on the mounting seat 100. The expanding drive assembly 220 drives the expanding structure 210 to expand the opening of the box body 500 to form a feeding port 510; the pushing mechanism 300 is used to push the stacked sheets into the box body 500 through the feeding port 510. The feeding-into-box structure 1000 provided by the present invention is simple to operate. The expanding device 200 can expand the feeding port 510, significantly improving the success rate of feeding assembly and reducing the risk of sheet wear.

[0057] Specifically, see Figure 4 as well as Figure 5 The expansion structure 210 includes two movable plates 211 movably mounted on the mounting base 100. The two movable plates 211 are configured to correspond to the opposite side walls of the box body 500 and have a movable range of moving closer to and away from each other. When moving away from each other, the two movable plates 211 drive the opposite side walls of the box body 500 to move away from each other, thereby expanding the opening of the box body 500 and forming the feeding port 510. It should be noted that, taking the rectangular box body 500 as an example, the two movable plates 211 can be arranged relative to the two long sides of the opening of the rectangular box body 500, or relative to the two short sides of the opening of the rectangular box body 500, as long as they can serve to expand the opening of the box body 500. In addition, in this embodiment, the two opposite movable plates 211 simultaneously expand the opposite side walls of the box body 500. Specifically, based on the original two movable plates 211, one movable plate 211 remains fixed while the other movable plate 211 moves to open the opening of the box body 500.

[0058] Further, referring to Figure 5 , the movable plate 211 has a proximal end proximal to the mounting area 110 and a distal end distal from the mounting area 110. Each movable plate 211 includes a flaring section 212 and a guide section 213, which are sequentially connected from proximal to distal. The flaring section 212 is configured to extend into the box body 500 to expand the opening of the box body 500, while the guide section 213 extends obliquely from proximal to distal, gradually away from the other movable plate 211. It should be noted that in this embodiment, the guide sections 213 of the two movable plates 211 are arranged at an angle relative to each other. This not only reduces motion interference between the two movable plates 211, but also reduces resistance to the flaring of the box body 500, preventing damage to the box body 500, thereby significantly improving assembly efficiency.

[0059] See also Figure 5The movable plate 211 further includes a connecting section 214 that bends and extends from the distal end of the guide section 213 toward the proximal direction; the flaring drive assembly 220 includes a driving cylinder 221, which drives the connecting section 214 connected to the movable plate 211. One end of the connecting section 214 is connected to the guide section 213, and the other end is connected to the flaring drive assembly 220. The bent and extended connecting section 214 allows the flaring drive assembly 220 to be positioned away from the box body 500 and the guide section 213, without interfering with each other's movement strokes. Specifically, the pushing mechanism 300 includes a pushing block 310 that is movable in the direction of approaching and away from the installation area 110, and a pushing drive structure for driving the pushing block 310 to move. When the pushing block 310 is close to the installation area 110, it pushes the stacked sheets into the box body 500 through the feeding port 510.

[0060] Furthermore, the movable plate 211 has a proximal end proximal to the mounting area 110 and a distal end distal to the mounting area 110. Each movable plate 211 is provided with a slot 215 extending along its thickness to the proximal end of the movable plate 211. The pusher block 310 is provided corresponding to the slot 215 and is configured to move along the slot 215 to push the stacked sheets into the box body 500. The slot 215 not only guides the pusher block 310 to the edge of the box opening, preventing collision and motion interference between the pusher block 310 and the movable plate 211, but also reduces the overall weight of the device, alleviating the operating pressure of the expansion drive assembly 220, thereby increasing the service life of the entire device.

[0061] Since both the sheet and the construction structure will exert force on the box body 500 during the process of feeding the materials into the box, in order to prevent the box body 500 from moving during the assembly process, causing damage to the box body 500 or reducing the success rate of assembly, the box body 500 needs to be limited after entering the assembly station. Specifically, the feeding structure 1000 also includes a limiting structure 400 detachably mounted on the installation area 110. The limiting structure 400 is used to limit the box body 500 in the pushing direction when the pushing mechanism pushes the stacked sheets. Figure 4 The mounting base 100 is provided with a receiving groove 120 on a side of the mounting area 110 away from the pushing mechanism 300. The limiting structure 400 includes a telescopic limiting top block 410, which is accommodated in the receiving groove 120 and can be movably extended from the receiving groove 120 to limit the position of the box body 500. The telescopic limiting top block 410 mainly limits the rear end of the box body 500 to prevent the box body 500 from moving during the assembly of the stacked sheets, which would affect the assembly success rate.

[0062] As shown in the figure, the installation area 110 has a first direction corresponding to the longitudinal direction of the feed port 510; multiple slots 215 are spaced apart along the first direction, and multiple pusher blocks 310 are provided corresponding to the multiple slots 215. Multiple pusher blocks 310 can improve the stability of pushing the stacked sheets and increase the success rate of packaging. In addition, the pusher blocks 310 are arranged on the slotted plate. The front end of the pusher block 310 is inserted into the slot and slides to push the rear end of the stacked sheets forward until it is immersed in the slot 215, and the rear end of the sheet is completely inserted into the box. During the movement of the sheet, the bottom sheet of the sheet is not in full contact with the slotted plate, which can effectively solve the problem of scratches on the stacked sheets.

[0063] The present invention discloses a feeding method and feeding structure 1000. The feeding method includes the following steps: an expansion device 200 expands an opening of a box body 500 located at an assembly station to form a feeding port 510; and a pushing mechanism 300 pushes stacked sheets into the box body 500 through the feeding port 510 along a pushing direction. The feeding method provided by the present invention can improve the success rate of feeding assembly and significantly reduce the risk of material wear.

[0064] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
