Description

Technical Field

[0001] This utility model relates to the field of packaging box palletizing, specifically a packaging box palletizing device. Background Technology

[0002] Palletizing equipment is a key piece of equipment in the field of industrial automation. It is mainly used to stack products such as packaging boxes, cartons, and bags into stacks according to a preset arrangement to facilitate warehousing, transportation, or loading and unloading. Its development is closely related to industrial automation, logistics efficiency improvement, and labor cost optimization.

[0003] Gravity always plays a role in the transportation of products. Therefore, when arranging products, palletizing devices usually use gravity to connect different transport mechanisms. In order to prevent products from falling due to gravity and causing mechanical collisions when they come into contact with the device plane, traditional palletizing devices often add cushioning structures such as springs. However, when the spring releases its elastic potential energy, it may rebound excessively, causing the packaging box to be thrown into the air due to the spring's rebound, thus disrupting the neat arrangement of the palletized products. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, traditional palletizing devices often add cushioning structures such as springs to prevent damage caused by mechanical collisions when products fall due to gravity and come into contact with the device plane. However, when the spring releases its elastic potential energy, it may rebound excessively, causing the packaging box to be thrown into the air due to the spring rebound, resulting in problems such as disrupting the neat arrangement of the palletized products. This utility model proposes a packaging box palletizing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a packaging box palletizing device, including a conveying device, a base is fixedly connected to one side of the conveying device, a housing is fixedly connected to one side of the base, and an anti-rebound mechanism is provided in the inner cavity of the housing.

[0006] The anti-rebound mechanism includes a stacking plate, one side of which is slidably connected to the inner cavity of the outer shell. A limit rod is fixedly connected to one side of the stacking plate. A limit member is fixedly connected to the inner wall of the base. The surface of the limit rod is slidably connected to the inner cavity of the limit member. A protrusion is fixedly connected to the inner wall of the limit member. A rotating shaft is rotatably connected to one side of the protrusion. A clamping plate is fixedly connected to the surface of the rotating shaft. One side of the clamping plate is in contact with one side of the protrusion. A first spring is fixedly connected to one side of the clamping plate. One end of the first spring is fixedly connected to the inner wall of the limit member.

[0007] Preferably, a telescopic damping rod is fixedly connected to one side of the palletizing plate, one end of the telescopic damping rod is fixedly connected to the inner wall of the outer shell, and a second spring is sleeved on the surface of the telescopic damping rod. One end of the second spring is fixedly connected to one side of the palletizing plate, and the other end of the second spring is fixedly connected to the inner wall of the outer shell.

[0008] Preferably, one side of the base is fixedly connected to a sliding plate, a toothed plate is slidably connected to the inner cavity of the sliding plate, a gear is rotatably connected to the inner cavity of the toothed plate, the teeth of the gear mesh with the teeth of the toothed plate, a support plate is fixedly connected to one side of the toothed plate, a buffer plate is fixedly connected to one side of the support plate, and a transmission mechanism is provided in the inner cavity of the base.

[0009] Preferably, the transmission mechanism includes a motor, one side of which is fixedly connected to the inner wall of the base, and the output end of the motor is fixedly connected to a rotating shaft, one end of which is fixedly connected to one side of a gear.

[0010] Preferably, a fixing post is fixedly connected to one side of the toothed plate, a connecting rod is rotatably connected to the surface of the fixing post, a positioning post is fixedly connected to one side of the sliding plate, and the inner cavity of the connecting rod is slidably connected to the surface of the positioning post.

[0011] Preferably, a groove is provided on one side of the sliding plate, and a slider is slidably connected to the inner wall of the groove, with the surface of the slider slidably connected to the inner cavity of the connecting rod.

[0012] Preferably, a push plate is fixedly connected to one side of the slider, and one side of the push plate is slidably connected to one side of the base.

[0013] The advantages of this utility model are:

[0014] This invention utilizes an anti-rebound mechanism. When a product falls onto a palletizing plate due to gravity, the plate is pressed down, compressing the second spring. Simultaneously, the palletizing plate moves a limiting rod downwards, contacting and pushing open a retaining plate. This compresses the first spring, accumulating elastic potential energy. When the limiting rod passes through a retaining plate, that plate is no longer under pressure, and the first spring releases its elastic potential energy, causing the retaining plate to reset and one side of it to be secured by a protrusion. When the second spring releases its elastic potential energy, the palletizing plate and limiting rod rise. The limiting rod then contacts the reset retaining plate again, but due to the protrusion's limitation, it cannot rise further, thus preventing excessive rebound. This solves the problem of traditional palletizing devices, which often add buffer structures like springs to prevent damage from mechanical collisions when products fall and contact the device surface. However, these springs may over-rebound when releasing their elastic potential energy, causing packaging boxes to be thrown into the air and disrupting the neat arrangement of the palletized products.

[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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a packaging box palletizing device. (Refer to...) Figures 1 to 5A packaging box palletizing device includes a conveying device 1, a base 2 fixedly connected to one side of the conveying device 1, a housing 3 fixedly connected to one side of the base 2, and an anti-rebound mechanism 4 provided in the inner cavity of the housing 3.

[0026] The anti-rebound mechanism 4 includes a pallet plate 401. One side of the pallet plate 401 is slidably connected to the inner cavity of the outer shell 3. A limit rod 402 is fixedly connected to one side of the pallet plate 401. A limit member 403 is fixedly connected to the inner wall of the base 2. The surface of the limit rod 402 is slidably connected to the inner cavity of the limit member 403. A protrusion 404 is fixedly connected to the inner wall of the limit member 403. A rotating shaft 405 is rotatably connected to one side of the protrusion 404. A locking plate 406 is fixedly connected to the surface of the rotating shaft 405. One side of the locking plate 406 is in contact with one side of the protrusion 404. A first spring 407 is fixedly connected to one side of the locking plate 406. One end of the first spring 407 is fixedly connected to the inner wall of the limit member 403. By setting the anti-rebound mechanism 4, when the product falls onto the pallet plate 401 due to gravity, the pallet plate 401 is pressed down, thereby compressing the second spring 6. At the same time, the pallet plate 401... 1. The limiting rod 402 moves downward, and the limiting rod 402 contacts and pushes open the clamping plate 406, causing the first spring 407 to be compressed and accumulate elastic potential energy. When the limiting rod 402 passes through one layer of clamping plate 406, the clamping plate 406 is no longer under the pressure of the limiting rod 402, and the first spring 407 releases elastic potential energy, causing the clamping plate 406 to reset, and one side of the clamping plate 406 is clamped by one side of the protrusion 404. When the second spring 6 releases elastic potential energy, the palletizing plate 401 and the limiting rod 402 rise, and the limiting rod 402 contacts the reset clamping plate 406 again. Due to the limitation of the protrusion 404, the limiting rod 402 cannot continue to rise, thereby preventing the palletizing plate 401 from excessively rebounding under the action of the second spring 6. As the number and total mass of products palletized on the palletizing plate 401 increase, the anti-rebound mechanism 4 can be activated multiple times by setting multiple layers of clamping plates 406.

[0027] Reference Figure 4 A telescopic damping rod 5 is fixedly connected to one side of the pallet 401. One end of the telescopic damping rod 5 is fixedly connected to the inner wall of the outer shell 3. A second spring 6 is sleeved on the surface of the telescopic damping rod 5. One end of the second spring 6 is fixedly connected to one side of the pallet 401, and the other end of the second spring 6 is fixedly connected to the inner wall of the outer shell 3. By setting the second spring 6, in order to prevent the pallet 401 from making hard contact with the product and causing damage to the product, when the product falls on the pallet 401 due to gravity, the pallet 401 is subjected to pressure and moves downward, causing the second spring 6 to deform and accumulate elastic potential energy, so that the downward speed of the pallet 401 and the product gradually decreases with the deformation of the second spring 6.

[0028] Reference Figure 2 and Figure 6One side of the base 2 is fixedly connected to the sliding plate 7. A toothed plate 8 is slidably connected to the inner cavity of the sliding plate 7. A gear 9 is rotatably connected to the inner cavity of the toothed plate 8. The teeth of the gear 9 mesh with the teeth of the toothed plate 8. A support plate 10 is fixedly connected to one side of the toothed plate 8. A buffer plate 11 is fixedly connected to one side of the support plate 10. A transmission mechanism 12 is provided in the inner cavity of the base 2. By setting the toothed plate 8 and the gear 9, when the gear 9 rotates, since the teeth of the gear 9 mesh with the teeth of the toothed plate 8, and since only half of the teeth of the gear 9 cannot mesh with the teeth on both sides of the toothed plate 8 at the same time, the rotation of the gear 9 drives the toothed plate 8 to switch left and right and move in opposite directions. Thus, the toothed plate 8 drives the support plate 10. The buffer plate 11, which is fixedly connected to the support plate 10, moves left and right. By setting the buffer plate 11, the products pushed into the inner cavity of one side of the outer shell 3 by the push plate 18 from the base 2 will first fall onto the buffer plate 11 extending from the base 2. This avoids the possibility that the same layer of products may be pushed off the base 2 one after another due to the different positions of the products on the base 2 when the push plate 18 pushes the products, thus making it impossible to arrange them. When the push plate 18 moves to the edge of the base 2 to complete the stacking, the buffer plate 11 will be driven by the toothed plate 8 to move to the other side of the outer shell 3 as the toothed plate 8 moves, so that the products originally carried by the buffer plate 11 in the outer shell 3 can fall onto the stacking plate 401 under the action of gravity.

[0029] Reference Figure 6 The transmission mechanism 12 includes a motor 1201. One side of the motor 1201 is fixedly connected to the inner wall of the base 2. The output end of the motor 1201 is fixedly connected to a rotating shaft 1202. One end of the rotating shaft 1202 is fixedly connected to one side of the gear 9. By setting the motor 1201, the motor 1201 works and controls the rotating shaft 1202 fixedly connected to its output end to rotate, thereby driving the gear 9 fixedly connected to one end of the rotating shaft 1202 to rotate.

[0030] Reference Figure 2 A fixed post 13 is fixedly connected to one side of the toothed plate 8. A connecting rod 14 is rotatably connected to the surface of the fixed post 13. A positioning post 15 is fixedly connected to one side of the sliding plate 7. The inner cavity of the connecting rod 14 is slidably connected to the surface of the positioning post 15. By setting the connecting rod 14, as the toothed plate 8 moves, it will drive the fixed post 13 fixedly connected to one side. Since the connecting rod 14 is rotatably connected to the surface of the fixed post 13 and the connecting rod 14 is limited by the positioning post 15, the movement of the fixed post 13 will drive one end of the connecting rod 14 to swing, causing the other end of the connecting rod 14 to swing in the opposite direction.

[0031] Reference Figure 2 A groove 16 is provided on one side of the sliding plate 7. A slider 17 is slidably connected to the inner wall of the groove 16. The surface of the slider 17 is slidably connected to the inner cavity of the connecting rod 14. By setting the groove 16 and the slider 17, the groove 16 limits the slider 17, so one end of the connecting rod 14 swings to drive the slider 17 to move left and right in the groove 16.

[0032] Reference Figure 1 A push plate 18 is fixedly connected to one side of the slider 17, and one side of the push plate 18 is slidably connected to one side of the base 2. By setting the push plate 18, the product falls onto the base 2. The push plate 18 moves under the drive of the slider 17. The push plate 18 can push the product transported from the conveying device 1 until the push plate 18 moves to the edge of the base 2, so that the products can be neatly arranged. The conveying device 1 is an existing structure and will not be described further.

[0033] Working principle: The conveyor 1 has two transport tracks, each corresponding to one side of the outer casing 3 for stacking. When the product is transported to the base 2 by the conveyor 1, the motor 1201 operates, controlling the rotation of the rotating shaft 1202 fixedly connected to its output end. This drives the gear 9 fixedly connected to one end of the rotating shaft 1202 to rotate. Because the teeth of the gear 9 mesh with the teeth of the gear plate 8, and because the gear 9 only has half of its teeth, it cannot mesh with the teeth on both sides of the gear plate 8 simultaneously. Therefore, the rotation of the gear 9 drives the gear plate 8 to switch left and right and move in opposite directions. As the gear plate 8 moves, it drives the gear plate 8 fixedly connected to one side of the base 2 to rotate. The fixed column 13 is rotatably connected to the connecting rod 14, and the connecting rod 14 is limited by the positioning column 15. Therefore, the movement of the fixed column 13 causes one end of the connecting rod 14 to swing, causing the other end of the connecting rod 14 to swing in the opposite direction. Since the slide groove 16 limits the slider 17, the swing of one end of the connecting rod 14 causes the slider 17 to move left and right within the slide groove 16. The push plate 18 moves under the action of the slider 17. The push plate 18 can push the products transported from the conveyor 1 until the push plate 18 moves to the edge of the base 2, so that the products can be neatly arranged on the buffer plate 11. As the toothed plate 8 moves, the buffer plate 11 is driven by the toothed plate 8 to move towards the outer shell 3 on the other side. This allows the product originally carried by the buffer plate 11 inside the outer shell 3 to fall onto the palletizing plate 401 under gravity. This causes the palletizing plate 401 to be pressed down, thereby compressing the second spring 6. At the same time, the palletizing plate 401 drives the limiting rod 402 to move down. The limiting rod 402 moves down and contacts and pushes open the clamping plate 406, causing the first spring 407 to be compressed and accumulate elastic potential energy. When the limiting rod 402 passes through one layer of clamping plate 406, that layer of clamping plate 406 is no longer under the pressure of the limiting rod 402, and the first spring 407... The elastic potential energy is released, causing the clamping plate 406 to reset and one side of the clamping plate 406 to be clamped by one side of the protrusion 404. When the second spring 6 releases the elastic potential energy, the stacking plate 401 and the limiting rod 402 rise. The limiting rod 402 contacts the reset clamping plate 406 again. Due to the limiting of the protrusion 404, the limiting rod 402 cannot continue to rise, thereby preventing the stacking plate 401 from excessively rebounding under the action of the second spring 6. As the toothed plate 8 drives the two ends of the connecting rod 14 to swing in opposite directions, the push plate 18 and the buffer plate 11 move relative to each other, thereby stacking on the left and right outer shells 3.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
