Description

Technical Field

[0001] The utility model relates to the technical field of carton processing equipment, in particular to a carton storage device. Background Art

[0002] A carton is a most common packaging material. Before being packed, it is usually in a flat shape. Generally, multiple cartons are stacked on top of each other and placed at a specific position for storage. When packaging is needed, the carton is taken down and folded to be used for packing items.

[0003] A vertical carton opener places the carton vertically in the carton storage. After the vertical carton is grabbed by a grabbing device, it is pulled open to hold items.

[0004] However, since the carton is placed vertically in the carton storage, when the gravity of the carton is large, the middle part of the vertically placed carton will collapse, causing the carton to deform before use, which is not convenient for opening the carton. Second, when the carton gets damp due to weather reasons, especially in the southern regions of China during the plum rain season when the air humidity is high, the carton gets damp and soft. When the carton is placed vertically, it will be squeezed and deformed, seriously affecting the storage and opening of the carton.

[0005] Therefore, there is a need for a new type of carton storage device that can store cartons and at the same time facilitate the transportation of multiple cartons simultaneously to facilitate the grabbing of cartons by the carton opener. Summary of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0042] It should be noted that in the embodiments of the present invention, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] In addition, the descriptions of “first”, “second”, etc. in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

[0044] The embodiment of the present invention provides a carton storage device, which can be used to store cartons stacked on each other to form a stack, and can transport the cartons out in sequence. During the transportation process, the cartons can be transported one by one, with high transportation efficiency and accuracy. At the same time, when the cartons stack is tilted or scattered, the stack can be sorted to prevent the stack from tilting and collapsing. Figures 1-4 As shown, the utility model provides a carton storage device, including a base frame and a base frame, the base frame provides a mounting base, and a conveying device 200 and a carrying device 300 are arranged on the base frame, wherein the conveying device 200 is arranged on the base frame to convey the cartons along a predetermined direction; the carrying device 300, the carrying device 300 is used to carry cartons stacked on each other, and includes a guide rod 301, a bottom plate 310 and a lifting drive device 320, wherein the guide rod 301 includes a plurality of vertically arranged on opposite sides of the base frame, and both ends of the bottom plate 310 are slidably connected to the guide rod 301 in the vertical direction, and an avoidance position 311 corresponding to the conveying device 200 is arranged on the bottom plate 310, and the lifting drive device 320 is fixedly installed on the base frame and is transmission-connected to the bottom plate 310 to drive the bottom plate 310 to move back and forth along the axis direction of the guide rod 301.

[0045] An extension rack 400 is also provided in front of the conveying device 200 along the conveying direction to receive the cartons conveyed by the conveying device 200. The extension rack 400 is linked to the conveying device so that the extension rack 400 and the conveying device 200 can move synchronously, and the cartons stacked on the carrying device can be stacked and conveyed.

[0046] When storing cartons, the cartons are stacked on top of the bottom plate 310 to form a carton stack. In the initial stage, the bottom plate 310 is located above the conveying device 200 under the drive of the lifting drive device 320, so that the cartons and the conveying device 200 are spaced apart from each other. When it is necessary to convey the cardboard, the bottom plate 310 moves towards the conveying device 200 under the drive of the lifting drive device 320, so that the lowermost carton comes into contact with the conveying device 200. Thus, the entire carton stack is conveyed under the frictional action between the conveying device 200 and the cartons, and the carton stack is conveyed along the conveying device and the extension frame at the same time. Furthermore, the carton stack is conveyed towards the outer side within the box storage. When storing the cartons, the cartons are placed flat on the bottom plate, and multiple cartons are stacked on top of each other to form a carton stack. By stacking the cartons after placing them flat, the cartons can be relatively stable. Compared with vertical carton openers, it can avoid the deformation of the cartons due to gravity within the box storage. At the same time, after the cartons are damp and soft, they can still be relatively stable and will not deform, which can ensure the carton opening work. And through this device, the entire carton stack can be conveyed, that is, the carton stack can be conveyed on the conveying device and the extension frame. By conveying the entire carton stack, it is convenient for the subsequent carton opening mechanism to sequentially remove the cartons from the carton stack for subsequent carton opening and packing work.

[0047] It can be imagined that the lifting drive device 320 moves the bottom plate 310 downward, so that the cartons are exposed on the avoidance position 311, and the conveying drive device moves along the avoidance position 311 towards the cartons. Furthermore, the cartons come into contact with the conveying device 200, and under the gravitational action of the carton stack, the lowermost carton is in tight contact with the conveying device 200. The entire carton stack is conveyed through the frictional force between the conveying device 200 and the cartons, and at the same time, it is conveyed towards the extension frame direction. Since the extension frame is linked to the conveying device, the conveying synchronization of the extension frame and the conveying device can be guaranteed, and the conveying of the carton stack is more stable.

The second drive motor 404 drives the second conveyor belt 403 to be transmitted on the drive shaft 402, so as to receive the cartons transmitted by the conveying device 200 and continue to convey the cartons forward on the second conveyor belt 403 and the roller 405. By setting the extension frame 400, the conveying distance of the cartons by the conveying device 200 can be extended, which is more convenient for subsequent processes to operate and process the cartons.

[0049] In this embodiment, a specific example of the structure of the conveying device 200 is given, such as Figure 4 As shown, the conveying device 200 includes a frame 201100.

A first conveyor belt 204 is sleeved on the drive rollers 202 and the driven rollers 203, and the drive roller 202 is in transmission connection with the second drive motor 404 to drive the drive roller 202 to rotate. By connecting the drive roller 202 to the second drive motor 404, the first conveyor belt 204 and the second conveyor belt 403 can be synchronously driven, so as to ensure the more stable and smooth conveying of the cartons.

The two ends of the roller are rotatably connected to the fixing plates 406 respectively, and a number of limiting columns 407 arranged vertically and spaced apart from each other are rotatably connected to at least one fixing plate 406. By moving the adjusting rod 408 along the axial direction, the position of the roller 405 is adjusted, which is convenient for conveying different cartons. At the same time, the limiting columns 407 are arranged on at least one fixing plate 406 to limit the cartons being conveyed to prevent the conveying from deviating.
