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

Therefore, the above terms should not be understood as limiting the present application.

[0042] The present application is further described in detail below in conjunction with the accompanying drawings. Figures 1 to 7 illustrate.

[0043] Embodiment 1

[0044] The present application provides a stacking regularization device 1 (hereinafter referred to as regularization device 1), such as Figures 1 to 4 As shown, the tidying device 1 includes a mounting support 3, a driving mechanism 4 and an alignment mechanism 2, the driving mechanism 4 is connected to the mounting support 3, the driving mechanism 4 is connected to the alignment mechanism 2, and the alignment mechanism 2 is used to align the misplaced sheet materials in the stack 24 to achieve the tidying of the stack 24, so as to facilitate the subsequent storage or retrieval of the stack 24 materials.

[0045] Specifically, Figures 1 to 4 , Figure 6 As shown, the alignment mechanism 2 includes at least two alignment parts arranged opposite to each other, and a space for accommodating the stack 24 is formed between the alignment parts. The stack 24 is located between the two alignment parts. The driving mechanism 4 is connected to at least one of the alignment parts. The driving mechanism 4 can drive the connected alignment part to move, thereby changing the spacing between the alignment parts. When the stack 24 is placed between the alignment parts, the driving mechanism 4 drives the alignment part to move slowly. During the movement, the spacing between the alignment parts gradually decreases. The alignment part pushes the sheet material that is displaced and moves outward, so that the displaced sheet material is reset. When the alignment part cannot move, it indicates that all the sheet materials are completely aligned, thereby achieving the regularity of the stack 24 material.

[0046] It should be noted that the initial spacing between the alignment parts is greater than the length of the stack 24, which, on the one hand, prevents the stack 24 from being unable to be inserted and causing contact, and on the other hand, reserves space for some sheet materials in the stack 24 to be dislocated and moved outward, so that the alignment mechanism 2 can fully regularize the stack 24.

[0048] like Figures 4 to 6 As shown, the alignment portion on the side of the driven wheel 12 close to the screw 8 is rotatably connected to the screw 8; the alignment portion includes a connecting block 14 and a limiting member 15, and a rotating hole for the screw 8 to pass through is provided in the connecting block 14, and a thread matching the thread of the screw 8 is provided on the rotating hole, thereby realizing the connection between the connecting block 14 and the screw 8. When the screw 8 rotates, the connecting block 14 will make a linear displacement along the extension direction of the screw 8; the upper end of the connecting block 14 is fixedly connected to the limiting member 15, and when the connecting block 14 moves, the limiting member 15 can move with the connecting block 14; the limiting member 15 is used to limit the side of the stack 24, and the limiting member 15 extends upward, and its length is greater than the thickness of each stack of stacks 24, so that the limiting member 15 can fully regularize the stack 24.

[0049] It should be noted that in the present application, two alignment parts are provided, wherein the screw rod 8 is connected to the alignment part on the side close to the driven wheel 12, and the driving mechanism 4 is used to drive the alignment part to move relative to the other alignment part, thereby changing the spacing between the two alignment parts to achieve the regularity of the laminations 24; and the two alignment parts are provided on the same plane.

[0050] Further, such as Figure 1 , Figure 3 , Figure 6 As shown, the alignment mechanism 2 also includes a connecting plate 16, and the alignment part is connected to the connecting plate 16; specifically, the connecting plate 16 is a plate-like structure, the limiter 15 is connected to the upper end surface of the connecting plate 16, the connecting block 14 is fixedly connected to the lower end surface of the connecting plate 16, and at least two limiters 15 are provided on the connecting plate 16, and the two limiters 15 are spaced apart on the connecting plate 16, and the two limiters 15 limit the two sides of the stack 24 respectively, thereby increasing the point of action on the stack 24 to accelerate the regularization effect of the stack 24.

[0051] Embodiment 2

[0052] This embodiment is further expanded on the basis of the first embodiment;

[0053] In this embodiment, if Figure 6 As shown, the screw rod 8 is located between the two alignment parts, so that the screw rod 8 can act evenly on the two alignment parts; a slider 22 is provided on the mounting support 3, and the upper end of the slider 22 is fixedly connected to the lower end of the connecting plate 16, and sliders 22 are provided on both sides of the connecting plate 16, and the sliders 22 are symmetrically arranged on both sides of the screw rod 8; a guide rail 23 is provided on the mounting support 3, and the guide rail 23 is fixedly connected to the upper end surface of the mounting plate 25, and the guide rail 23 is parallel to the length direction of the screw rod 8, and the guide rail 23 and the screw 8 are spaced apart. The length of the guide rail 23 is slightly smaller than the length of the mounting plate 25, and the slider 22 is slidably connected to the guide rail 23, so that when the alignment part moves, there are support points on both sides, which is beneficial to the stable movement of the alignment part, and the guide rail 23 can play a guiding role, so that the alignment part can move along the guide rail 23, avoiding deviation of the alignment part during movement, which is beneficial to improving the regularity and stability of the alignment mechanism 2 for the lamination 24.

[0054] Embodiment 3

[0055] This embodiment further expands the limiting member 15 based on any of the above embodiments;

[0056] In this embodiment, if Figure 5 As shown, the limiting member 15 includes a connecting shaft 19 and a rotating drum 20. The rotating drum 20 is sleeved on the outside of the connecting shaft 19. A bearing 21 is provided between the connecting shaft 19 and the rotating drum 20. The bearings 21 are respectively arranged at the upper and lower ends of the connecting shaft 19. The bearings 21 are sleeved on the connecting shaft 19. The inner wall of the rotating drum 20 fits the outer wall of the bearing 21. The connecting shaft 19 is fixedly connected to the connecting plate 16, so that the rotating drum 20 can rotate relative to the connecting shaft 19. Therefore, when the limiting member 15 touches the stacking sheet 24, the rotating drum 20 can rotate relative to the stacking sheet 24, thereby reducing the friction between the rotating drum 20 and the stacking sheet 24, thereby avoiding the stacking sheet 24 from wearing the limiting member 15, which is beneficial to improving the service life of the alignment mechanism 2.

[0057] Embodiment 4

[0058] This embodiment is further expanded on the basis of any of the above embodiments;

The support bracket 17 is arranged on the side of the limit member 15 away from the stacking plate 24. The support bracket 17 is used to support the limit member 15 to prevent the limit member 15 from being pushed back by the stacking plate 24 when acting on the stacking plate 24, thereby causing the limit member 15 to shift.

[0060] like Figure 6 As shown, the cross-section of the support bracket 17 is an F structure, which includes a vertical plate, a first horizontal plate and a second horizontal plate. The first horizontal plate is arranged in parallel with the second horizontal plate. The ends of the first horizontal plate and the second horizontal plate away from the limiting member 15 are connected to the upper end of the vertical plate. The lower end of the vertical plate is fixedly connected to the connecting plate 16. A roller 18 is provided between the first horizontal plate and the second horizontal plate. The roller 18 is rotatably connected to the first horizontal plate and the second horizontal plate. The roller 18 is in contact with the limiting member 15, so that there is rolling friction between the support bracket 17 and the limiting member 15, which can reduce the contact wear between the support bracket 17 and the limiting member 15.

[0061] Further, such as Figure 7 As shown, the end of the support bracket 17 close to the limit is special-shaped, and a matching edge is provided at the end thereof, which is matched to form a V-shaped structure, and the angle of its opening is an obtuse angle. The matching edge acts on the outside of the limit member 15, and the matching edge is used to expand the support area of ​​the limit member 15. Rollers 18 are respectively provided at both ends of the matching edge, that is, at least two rollers 18 are provided on a support bracket 17, and the rollers 18 are arranged at intervals, so as to improve the support stability of the limit member 15.

When the screw 8 rotates, the two alignment parts can be driven to move toward or oppositely at the same time, so that the spacing adjustment speed of the alignment parts is accelerated, and the adjustment efficiency of the alignment mechanism 2 on the laminations 24 can be accelerated.

[0065] Embodiment 6

[0066] The difference between this embodiment and the first embodiment is that, in this embodiment, the driving mechanism 4 includes a driving motor 7 and a lead screw (not shown in the figure), the driving motor 7 is fixedly connected to the mounting support 3, the driving motor 7 is connected to the upper end surface of the mounting plate 25, one end of the lead screw is connected to the driving motor 7, and the other end is fixedly connected to the connecting block 14 of the alignment part close to the lead screw.

[0067] In addition, the driving mechanism 4 can also be driven by a cylinder, a linear motor or a hydraulic cylinder, as long as it can achieve linear reciprocating drive.

[0068] It should be noted that the stacking arrangement device 1 of the present application can be installed on both sides of the conveyor belt of the conveying device to arrange and align the stacking sheets 24 on the conveyor belt.
