Description

Technical Field

[0001] This utility model relates to the field of stacking device technology, specifically an automatic stacking device for finished plastic storage boxes. Background Technology

[0002] Plastic storage boxes are widely used in home storage, logistics and transportation due to their lightweight, durable and stackable characteristics. The stacking of finished products is a key link in the production process, and efficient, automatic and stable stacking is required to reduce labor costs and improve warehousing efficiency.

[0003] Chinese utility model patent CN221164998U discloses a container stacker, including a moving component. Two columns are fixedly connected to the upper end of the moving component, and a top plate is fixedly connected to the upper ends of the two columns. A moving frame is slidably connected between the two columns. First grooves are formed on the opposite sidewalls of the two columns, and limiting mechanisms for restricting the movement of the moving frame are provided in both first grooves. A gripping component is installed at the inner bottom of the moving frame, and a second groove is formed at the inner top of the moving frame. A clamping mechanism for gripping the container is provided in the second groove. This utility model has a reasonable structure. By setting up the clamping mechanism, it achieves the clamping of the container, improving the stability of the container during transportation and preventing the container from falling and causing danger.

[0004] However, in the process of using this utility model, the stacker crane in the prior art focuses on the single operation mode of "grabbing, handling and stacking", lacks the adaptable structure to the continuous conveyor line of finished products, and is difficult to meet the continuous stacking requirements after the mass production of plastic storage boxes. It requires manual transfer and connection, which is inefficient. Therefore, an automatic stacking device for finished plastic storage boxes is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic stacking device for finished plastic storage boxes. It has the advantages of being adapted to the characteristics of plastic storage boxes and having smooth connections. It solves the problem that the stacker cranes in the prior art focus on a single operation mode of "grabbing, handling and stacking", lack a structure adapted to the continuous conveyor line of finished products, and cannot meet the continuous stacking requirements after the mass production of plastic storage boxes. It also solves the problem of low efficiency caused by the need for manual transfer and connection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic stacking device for finished plastic storage boxes, including a support frame and a roller conveyor device disposed inside the support frame. The support frame is externally fixedly connected to an installation frame extending to its top, and the installation frame is internally provided with a stacking mechanism capable of stacking the storage boxes.

[0007] The stacking mechanism includes a limiting rod fixedly connected inside the mounting frame, an mounting rod fixedly connected inside the mounting frame, a support block rotatably connected to the outside of the mounting rod, a telescopic cylinder extending to its top fixedly connected inside the support frame, and a top plate capable of pushing the storage box out fixedly connected to the output end of the telescopic cylinder.

[0008] Furthermore, the limiting rod is located at the top of the mounting rod and the support block, and a limiting groove is formed on the side of the support block near the limiting rod.

[0009] Furthermore, there are two mounting brackets, which are symmetrically distributed on both sides of the support frame, and each mounting bracket has four limiting rods inside.

[0010] Furthermore, a positioning rod extending into the support frame is fixedly connected to the bottom of the top plate, and the top plate is located between two rollers in the roller conveyor device.

[0011] Furthermore, the mounting frame is provided with a limiting strip inside, which can limit the position of the storage box. A connecting block extending to the outside of the mounting frame is fixedly connected to the limiting strip. A fastener is threadedly connected to the side of the connecting block away from the limiting strip.

[0012] Furthermore, the limiting strip has an L-shaped cross-section, and the mounting bracket has an internal movable groove that matches the connecting block.

[0013] Furthermore, an mounting plate is fixedly connected to the upper surface of the support frame, and an electric push rod is fixedly connected to the side of the mounting plate away from the roller conveyor. A positioning plate is fixedly connected to the output end of the electric push rod.

[0014] Furthermore, there are two mounting plates, which are symmetrically distributed on the top of the support frame, and anti-slip pads are fixedly connected to the opposite side of each of the two positioning plates.

[0015] Compared with the prior art, this utility model provides an automatic stacking device for finished plastic storage boxes, which has the following beneficial effects:

[0016] 1. This automatic stacking device for finished plastic storage boxes adopts a collaborative structure of "roller conveyor + top plate". The roller conveyor realizes continuous automatic conveying of finished plastic storage boxes, and the top plate is precisely located between the two rollers. The storage boxes can be directly pushed to the stacking station without additional transfer, realizing seamless connection between conveying and stacking. By setting support blocks and limit rods, the storage boxes can be sent to the support blocks by the action of the top plate, realizing the stacking of storage boxes from bottom to top, thereby achieving the effect of automatic stacking.

[0017] 2. This automatic stacking device for finished plastic storage boxes, through the cooperation of the limiting strip, connecting block, and movable groove, allows for adjustment of the lateral position via fasteners. An electric push rod drives the positioning plate to adjust the spacing. Both mechanisms work together to adapt to plastic storage boxes of different lengths and widths. No replacement of adapter parts is required; simple adjustments are all that's needed to meet the stacking needs of various product specifications. This solves the problem of the stacker cranes in the comparison documents, which focus on a single-operation mode of "grabbing, handling, and stacking," lacking a compatible structure with continuous conveyor lines for finished products. This makes it difficult to meet the continuous stacking needs after mass production of plastic storage boxes, requiring manual transfer and connection, resulting in low efficiency.

[0023] 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.

[0024] Please see Figures 1 to 3 An automatic stacking device for finished plastic storage boxes in this embodiment includes a support frame 1 and a roller conveyor 2 disposed inside the support frame 1. An installation frame 3 extending to the top of the support frame 1 is fixedly connected to the outside of the support frame 1. A stacking mechanism capable of stacking storage boxes is disposed inside the installation frame 3. The stacking mechanism includes a limit rod 4 fixedly connected inside the installation frame 3, an installation rod 5 fixedly connected inside the installation frame 3, a support block 6 rotatably connected to the outside of the installation rod 5, and a telescopic cylinder 7 extending to the top of the support frame 1 fixedly connected inside the support frame 1. A top plate 8 capable of pushing the storage boxes out is fixedly connected to the output end of the telescopic cylinder 7.

[0025] Specifically, the limiting rod 4 is located at the top of the mounting rod 5 and the support block 6. The support block 6 has a limiting groove on the side near the limiting rod 4. There are two mounting brackets 3, which are symmetrically distributed on both sides of the support bracket 1. Each mounting bracket 3 has four limiting rods 4 inside. The lower surface of the support block 6 is a slope. When the side of the support block 6 away from the limiting rod 4 is on a horizontal line, the other side of the support block 6 is in contact with the limiting rod 4.

[0026] It should be noted that when the telescopic cylinder 7 moves the top plate 8 upward, the top plate 8 lifts the storage box upward. As the storage box continues to rise, it will squeeze the support block 6, causing the support block 6 to rotate. When the storage box is above the support block 6, the telescopic cylinder 7 moves the top plate 8 downward. Due to gravity, the storage box will move downward at the same time. The support blocks 6 on both sides and the limiting rod 4 will support the storage box. The subsequent storage boxes can then be stacked downward in sequence.

[0027] Please see Figure 1 and Figure 4 In this embodiment, the mounting frame 3 is provided with a limiting strip 9 that can limit the storage box. The limiting strip 9 is fixedly connected to a connecting block 10 that extends to the outside of the mounting frame 3. The side of the connecting block 10 away from the limiting strip 9 is threadedly connected to a fastener 11.

[0028] Specifically, the limiting strip 9 has an L-shaped cross-section, and the mounting bracket 3 has an internal movable groove 12 that matches the connecting block 10.

[0029] It should be noted that by loosening the fastener 11, the connecting block 10 can be pushed to move laterally along the movable groove 12, thereby adjusting the spacing of the limit strips 9 on both sides to adapt to plastic storage boxes of different widths; tightening the fastener 11 can lock the position of the limit strip 9. Its L-shaped structure can limit the lateral displacement of the storage box and prevent the storage box from tipping over when stacked.

[0030] Please see Figure 1 In this embodiment, an mounting plate 13 is fixedly connected to the upper surface of the support frame 1. An electric push rod 14 is fixedly connected to the side of the mounting plate 13 away from the roller conveyor device 2. A positioning plate 15 is fixedly connected to the output end of the electric push rod 14. There are two mounting plates 13, which are symmetrically distributed on the top of the support frame 1. Anti-slip pads are fixedly connected to the opposite sides of the two positioning plates 15.

[0031] Specifically, the initial distance between the two positioning plates 15 is greater than the width of the largest storage box. When the storage box is transported to the stacking station, the electric push rod 14 synchronously drives the positioning plates 15 to move towards the center until the anti-slip pad is in contact with the side wall of the storage box, thus achieving precise positioning. After positioning is completed, the electric push rod 14 drives the positioning plates 15 to reset, without affecting the subsequent transport of the storage box.

[0032] The working principle of the above embodiments is as follows:

[0033] According to the size of the plastic storage box, adjust the spacing of the limit strips 9, loosen the fasteners 11, move the connecting block 10 to the appropriate position and then tighten it. The finished plastic storage box is conveyed to the stacking station at a uniform speed by the roller conveyor device 2. When the storage box triggers the limit switch, the roller conveyor device 2 stops. The electric push rod 14 drives the two positioning plates 15 to move closer to the middle. The anti-slip pad is attached to the side wall of the storage box to prevent it from shifting. After positioning, the electric push rod 14 resets, the telescopic cylinder 7 is vented and extends upward, driving the top plate 8 to lift the storage box. The bottom of the storage box presses the support block 6, causing it to rotate outward around the mounting rod 5 and pass smoothly through the area of ​​the support block 6. When the storage box rises to the preset height, the telescopic cylinder 7 is vented in the opposite direction and resets downward. The storage box falls under the action of gravity, and the two side support blocks 6 automatically rotate and reset, cooperating with the limit rod 4 to support the bottom of the storage box, completing the first layer of stacking.

[0034] Roller conveyor 2 resumes operation, sending the next storage box to the stacking station, repeating the positioning and lifting process; after the new storage box is lifted, it falls down along the limit rod 4 and is stacked on top of the first layer of storage boxes, and the support block 6 lifts and supports it again; this cycle can achieve automatic stacking of three to five layers. After stacking is completed, the entire stack of storage boxes is removed manually or by a robotic arm, and the device continues to carry out subsequent stacking operations.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
