Description

Technical Field

[0001] This utility model relates to the field of automated stacking equipment technology, and in particular to the palletizing machine unfolding mechanism. Background Technology

[0002] Palletizers are widely used automated equipment in modern industrial production. They are mainly used to automatically stack materials on pallets or carts according to predetermined rules, replacing heavy manual handling and improving production efficiency.

[0003] In certain industries, such as leather processing, textiles, or flexible materials manufacturing, palletizers need to handle materials that are not standard, regular boxes, but rather irregularly shaped, soft, and have many small corners and edges, such as flexible leather or sheet materials.

[0004] Existing palletizing machines often rely solely on the material's own gravity when releasing flexible materials from the end of the conveyor belt onto the carriage below. Due to the material's irregularity and softness, its edges and corners are prone to curling, folding, or piling during the descent, preventing it from landing flat on the carriage. These creases or wrinkles generated during stacking become fixed under the pressure of subsequent layers of material, making them difficult or impossible to eliminate in later processing. This severely affects the quality and yield of the final product, constituting a pressing technical challenge in this field.

[0005] Therefore, this utility model proposes a palletizing machine unfolding mechanism to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a palletizing machine unfolding mechanism, which aims to improve the problem in the prior art that when handling flexible materials, the materials are prone to curling and wrinkling during the falling process due to their irregularity and softness, resulting in uneven stacking and affecting product quality.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The palletizer unfolding mechanism includes a palletizer beam, a rotary cylinder, a central rotating shaft, a stainless steel swing arm, and a carriage. The rotary cylinder is mounted on the palletizer beam. The central rotating shaft is connected to the output end of the rotary cylinder via a coupling. The stainless steel swing arm is fixedly connected to the lower part of the central rotating shaft. The carriage is located below the stainless steel swing arm and also includes an alignment mechanism.

[0009] The alignment mechanism is mounted on the stainless steel swing arm. The alignment mechanism includes a connecting plate, which is fixed to the stainless steel swing arm. A sliding column is slidably connected to the connecting plate. A rotating block is rotatably connected to the front end of the sliding column. A nylon roller is installed at the end of the rotating block. A spring is sleeved on the outer periphery of the sliding column.

[0010] Preferably, the two ends of the spring abut against the actuating parts of the connecting plate and the sliding column, respectively;

[0011] Preferably, it further includes a connecting shell, which is encapsulated outside the connection between the coupling and the central rotating shaft;

[0012] Preferably, a limit mechanism is also installed on the stainless steel swing arm;

[0013] Preferably, the limiting mechanism includes a pushing column, a first sliding shell, a second sliding shell, and a limiting clamp. The pushing column is driven by a power source to push the first sliding shell and the second sliding shell to slide relative to each other. Furthermore, the limiting mechanism also includes a connecting column that connects the first sliding shell, the second sliding shell, and the limiting clamp.

[0014] Preferably, a rubber buffer plate is fixed to the side of the limiting clamp facing the material;

[0015] Preferably, the limiting mechanism further includes a limiting post, which is used to limit the maximum sliding distance between the first sliding shell and the second sliding shell;

[0016] Preferably, the limiting mechanism further includes a positioning post, which is used to maintain the posture of the limiting clamp during movement.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem of irregular flexible materials folding and wrinkling due to gravity and uneven edges when stacked and falling, by setting a stainless steel swing arm driven by a rotary cylinder and integrating a straightening mechanism and a limiting mechanism on the swing arm. The straightening mechanism straightens the edges of the material when the swing arm swings, and the limiting mechanism guides and positions the material in a coordinated operation. This achieves the effect of laying the material flat on the cart, avoiding creases that cannot be eliminated later, and significantly improving product quality.

[0019] 2. This utility model, through the combination structure of nylon rollers, springs, sliding columns and rotating blocks in the straightening mechanism, solves the problem that the rigid mechanism used in the prior art is prone to damage or tearing of the material surface due to pulling when handling flexible materials. It achieves the effect of being able to adapt to the irregular contour of the material, perform flexible sorting and straightening, reduce friction and rigid impact, and effectively protect the surface of the material.

[0020] 3. This utility model uses a limiting mechanism with a push column-driven limiting clamp, and works in conjunction with a limiting column and a positioning column for precise control. A rubber buffer plate is set on the limiting clamp, which solves the problem that the material may still shift or curl again during the falling process after being unfolded, resulting in inaccurate stacking position. It achieves precise limiting and buffering guidance of the edge of the unfolded material, prevents secondary folding, ensures the consistency of the stacking position, and improves the stability of the mechanism operation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5 This utility model provides an embodiment of a palletizer unfolding mechanism, including a palletizer beam 1 and a rotary cylinder 2 mounted on the palletizer beam 1. The palletizer beam 1 serves as a fixed base for the entire device, while the rotary cylinder 2 provides rotational power. A central rotating shaft 4 is connected to the output end of the rotary cylinder 2 via a coupling 3. A stainless steel swing arm 5 is fixedly connected to the lower part of the central rotating shaft 4, and a carriage 6 is located below the stainless steel swing arm 5 to receive materials. One of the core structures of this embodiment is the alignment mechanism 8 mounted on the stainless steel swing arm 5. The alignment mechanism 8 includes a connecting plate 805, which is fixed to the stainless steel swing arm 5. A sliding column 801 is slidably connected to the connecting plate 805. A rotating block 803 is rotatably connected to the front end of the sliding column 801, and a nylon roller 804 is mounted at the end of the rotating block 803. Furthermore, a spring 802 is sleeved on the outer periphery of the sliding column 801, and the two ends of the spring 802 abut against the connecting plate 805 and the action part on the sliding column 801, respectively.

[0030] The palletizer's unfolding mechanism also includes a connecting shell 9, which is encapsulated outside the connection between the coupling 3 and the central rotating shaft 4. It also includes a limiting mechanism 7, which is also mounted on the stainless steel swing arm 5. The limiting mechanism 7 includes a pushing column 701, a first sliding shell 702, a second sliding shell 703, and a limiting clamp 707. The pushing column 701 is driven by a power source to push the first sliding shell 702 and the second sliding shell 703 to slide relative to each other. The limiting mechanism 7 also includes a connecting column 705, which connects the first sliding shell 702, the second sliding shell 703, and the limiting clamp 707. This structure allows the movement of the pushing column 701 to be transmitted through the relative sliding of the first sliding shell 702 and the second sliding shell 703 via the connecting column 705, ultimately driving the limiting clamp 707 to move.

[0031] A rubber buffer plate 708 is fixed on the side of the limiting clamp 707 facing the material. In order to prevent the limiting mechanism 7 from moving too far, the limiting mechanism 7 also includes a limiting post 704. The limiting post 704 is used to limit the maximum sliding distance of the first sliding shell 702 and the second sliding shell 703. In order to ensure the stability and accuracy of the movement of the limiting clamp 707, the limiting mechanism 7 also includes a positioning post 706. The positioning post 706 is used to maintain the posture of the limiting clamp 707 during movement.

[0032] Working principle: When the sensor detects that the material is in place, the rotary cylinder 2 installed on the palletizer beam 1 is started. The rotational power of the rotary cylinder 2 is transmitted to the central rotating shaft 4 through the coupling 3, driving the central rotating shaft 4 to rotate. The central rotating shaft 4 then drives the fixedly connected stainless steel swing arm 5 to swing outward from the vertical position. During the swinging process of the stainless steel swing arm 5, the straightening mechanism 8 installed on the stainless steel swing arm 5 contacts the material first. The nylon roller 804 on the straightening mechanism 8 makes rolling contact with the edge of the material. The rotating block 803 rotates accordingly to adapt to the material contour. If wrinkles are encountered, the sliding column 801 slides inward under the buffer force provided by the spring 802. The overall flexible straightening and sorting are achieved through the connecting plate 805.

[0033] Simultaneously with or immediately following the action of the alignment mechanism 8, the limiting mechanism 7 is activated. The pushing column 701 within the limiting mechanism 7 begins to move under the drive of the power source, pushing the first sliding shell 702 and the second sliding shell 703 to slide relative to each other. This relative sliding is converted into the extension action of the limiting clamp 707 through the connecting column 705. The rubber buffer plate 708 of the limiting clamp 707 on the side facing the material contacts and limits or guides the edge of the material that has been unfolded by the alignment mechanism 8. The limiting column 704 is used to limit the maximum sliding distance of the first sliding shell 702 and the second sliding shell 703. The positioning column 706 is used to maintain the posture of the limiting clamp 707 during the movement. Under the synergistic action of the alignment mechanism 8 and the limiting mechanism 7, the material is flatly stacked on the carriage 6 below. During this process, the connecting shell 9 plays a role in sealing and protecting the connection between the coupling 3 and the central rotating shaft 4.
