Description

Technical Field

[0001] This utility model belongs to the technical field of palletized products, and in particular relates to a pallet-changing device for a fully automated loading line for palletized products. Background Technology

[0002] A pallet transfer device is a piece of equipment used in automated logistics systems, primarily for automatically transferring entire pallets of goods from one pallet to another. Its main functions include pallet replacement, pallet standardization, and automated handling, reducing manual intervention and improving logistics efficiency. Common types of transfer devices include robotic arm type, lifting and sliding type, and tilting type, each suitable for products of different shapes and characteristics. However, pallet transfer devices still have the following drawbacks in practical use:

[0003] The pallet changing device directly uses a clamping structure to flip the entire pallet of products during the pallet changing process, or it needs to transport the entire pallet of products over a long distance. During the operation, the pallet changing time is relatively long, and long-distance transportation leads to low efficiency or large equipment space occupation, making the work inconvenient and the pallet changing efficiency low.

[0004] Secondly, the pallet-changing device directly clamps the pallet and the product during operation. As the work progresses, the pallet is released and needs to be manually removed and replaced, which is inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a pallet changing device for a fully automated loading line for palletized products. By setting up a support frame, hollow compartment, clamping plate and fixing plate, it solves the problems of pallet changing devices requiring overall product flipping, long operation time and inconvenient pallet changing operation.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a pallet changing device for a fully automated loading line for palletized products. It includes a support frame, hollow chambers, clamping plates, and a fixing plate. A support platform is movably connected within the support frame. A fixing plate is fixed to the top center of the support platform. A push plate is located on the lower part of one side of the fixing plate. The support frame is U-shaped, with hollow chambers fixed to both ends of the top. Clamping plates are located on the sides of the two hollow chambers that are close to each other. During operation, a hydraulic cylinder fixes the support platform to the working plane via the support frame and an extension plate. An electric push rod is fixed within the hollow chamber and drives the clamping plate to move. During the movement of the clamping plate, the palletized products on the support platform are clamped onto it. The fixing plate pushes the push plate, thus pushing the pallet out.

[0008] Furthermore, an extension plate is fixed to one end of the support frame, and hydraulic cylinders are fixed at two corners at the bottom of the support frame and the top of the extension plate that are far apart from each other. The support frame adopts a U-shaped structure, with an extension plate welded to one end to increase stability. The hydraulic cylinders are symmetrically installed at the four corners at the bottom of the support frame and the top of the extension plate to ensure that the support platform can be raised and lowered smoothly.

[0009] Furthermore, the extension and retraction end of the hydraulic cylinder is fixed with a piston rod, and the top ends of the four piston rods are respectively fixed at the four corners of the bottom of the support platform. The top ends of the piston rods of the hydraulic cylinder are fixed at the four corners of the support platform, and the platform is precisely raised and lowered by a synchronous controller.

[0010] Furthermore, each of the two clamping plates is symmetrically fixed with a reinforcing plate on the side away from each other. The reinforcing plate is supported on the top of the hollow chamber. The outer side of the clamping plate is welded with a reinforcing plate and abuts against the top of the hollow chamber to enhance the rigidity during clamping and prevent deformation.

[0011] Furthermore, each of the two hollow chambers is symmetrically fixed with an electric push rod. Two movable holes are opened on the side of the hollow chamber near the clamping plate. The telescopic end of the electric push rod passes through the movable hole and is fixed to the hollow chamber. The electric push rod is installed inside the hollow chamber, and its telescopic end passes through the movable hole and connects to the clamping plate, synchronously driving the two clamping plates to clamp or release the product.

[0012] Furthermore, the fixing plate is positioned directly above the extension plate, and electric push rods are symmetrically fixed on the side of the fixing plate away from the support frame. The telescopic end of the electric push rod passes through the fixing plate and is fixedly connected to the push plate. The electric push rod is fixed to the top of the support platform, and the fixing plate is vertically fixed to the support platform. The electric push rods on both sides drive the push plate to move horizontally, which is used to push out the old tray or reset it.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of long operation time required for pallet changing devices that require the entire product to be flipped during pallet changing by setting up a support frame, hollow compartment, and clamping plate. When pallet changing is required, the pallet is first placed on the support platform. After the position is fixed by the fixing plate and push plate under the movement of the forklift, all hydraulic cylinders are activated. The first electric push rod in the hollow compartment drives the clamping plate to move. During the movement of the clamping plate, after the clamping plate clamps and sets the product on the pallet, the hydraulic cylinders on the support frame and extension plate are activated to drive the piston rod to lower the support platform. After the pallet is removed, a new pallet is placed on the support platform. Then, the hydraulic cylinders are activated, and the piston rod drives the support platform to rise until it supports the bottom of the entire pallet of products, providing support for the entire pallet of products. This eliminates the need for the entire product to be flipped during pallet changing, and the operation time is shortened.

[0015] This invention solves the problem of inconvenient pallet replacement operation in whole-pallet product changing devices by setting up a support frame and a fixing plate. When changing pallets, the whole pallet is placed on the support platform, and then two clamping plates are driven to move closer together by an electric push rod. After the two clamping plates move closer together, they are supported on the hollow chamber by a reinforcing plate to increase the clamping effect of the clamping plates. After the clamping plates clamp the whole pallet, the whole pallet is clamped. Then, the hydraulic cylinder is activated to drive the piston rod to descend, which in turn lowers the support platform. After the support platform descends, an electric push rod is activated, which drives a push plate. Under the push of the push plate, the pallet is pushed away from the support platform, making the pallet replacement operation of the whole-pallet product changing device more convenient.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-5 This utility model relates to a pallet-changing device for a fully automated loading line for palletized products. It includes a support frame 1, a hollow compartment 2, a clamping plate 3, and a fixing plate 4. A support platform 104 is movably connected within the support frame 1, supporting the hollow compartment 2 and the clamping plate 3. During operation, the support platform 104 supports the entire palletized product and the pallet itself. A fixing plate 4 is fixed to the top center of the support platform 104. The fixing plate 4 is connected to an electric push rod 402 and a push plate 401 on the support platform 104. A push plate 401 is provided on the lower part of one side of the 4. The push plate 401 moves horizontally under the drive of the electric push rod 402, pushing the pallet out along the side of the support platform 104. The support frame 1 is U-shaped, and hollow chambers 2 are fixed at both ends of the top. The hollow chambers 2 fix the electric push rod 302 in them, pushing the clamping plate 3 to move. The clamping plates 3 are provided on the side of the two hollow chambers 2 that are close to each other. The entire pallet of products is clamped on the clamping plates 3 under the push of the electric push rod 302.

[0026] Specifically, an extension plate 101 is fixed to one end of the support frame 1, and hydraulic cylinders 102 are fixed at two corners at the bottom of the support frame 1 and the top of the extension plate 101, which are far apart from each other. The support frame 1 increases the support area through the extension plate 101, and the four hydraulic cylinders 102 are controlled by the same controller to synchronously drive the support platform 104 to rise and fall.

[0027] Furthermore, the extension end of the hydraulic cylinder 102 is fixed with a piston rod 103, and the top ends of the four piston rods 103 are respectively fixed at the four corners of the bottom of the support platform 104. When the hydraulic cylinder 102 is working, it drives the piston rods 103 to rise and fall, thereby driving the support platform 104 to rise and fall.

[0028] The operation process of this embodiment is as follows: During operation, when it is necessary to change pallets of products, the pallet is first placed on the support platform 104. Under the movement of the forklift, the position is fixed by the fixing plate 4 and the push plate 401. Then, all the hydraulic cylinders 102 are started, and the electric push rod 302 in the hollow compartment 2 is started. The electric push rod 302 drives the clamping plate 3 to move. During the movement of the clamping plate 3, after the clamping plate 3 clamps and sets the products on the pallet, the hydraulic cylinders 102 on the support frame 1 and the extension plate 101 are started to drive the piston rod 103 to drive the support platform 104 to descend. After the pallet is removed, a new pallet is replaced on the support platform 104. Then, the hydraulic cylinders 102 are started, and the piston rod 103 drives the support platform 104 to rise until it supports the bottom of the entire pallet of products, thus providing support for the entire pallet of products. Specific Implementation Example 2

[0029] Please see Figure 1 , 3 4, 5. Based on the first specific embodiment, each of the two clamping plates 3 is symmetrically fixed with a reinforcing plate 301 on the side away from each other. The reinforcing plate 301 is supported on the top of the hollow chamber 2. The clamping plate 3, in cooperation with the reinforcing plate 301, increases the supporting effect of the clamping plate 3 on the hollow chamber 2.

[0030] Specifically, each of the two hollow chambers 2 has an electric push rod 302 symmetrically fixed inside. Two movable holes 201 are opened on the side of the hollow chamber 2 near the clamping plate 3. The telescopic end of the electric push rod 302 passes through the movable hole 201 and is fixed to the hollow chamber 2. All the electric push rods 302 are controlled to move synchronously by the same controller. The telescopic end of the electric push rod 302 is movably connected to the movable hole 201, and the clamping plate 3 is driven to move by the electric push rod 302.

[0031] Furthermore, the fixing plate 4 is positioned directly above the extension plate 101. On the side of the fixing plate 4 away from the support frame 1, electric push rods 402 are symmetrically fixed. The telescopic end of the electric push rods 402 passes through the fixing plate 4 and is fixedly connected to the push plate 401. The electric push rods 402 are fixed to the top of the support platform 104. The two electric push rods 302 are controlled by the same controller to move synchronously. The electric push rods 402 drive the push plate 401, which in turn pushes the tray on the support platform 104.

[0032] The operation process of this embodiment is as follows: During operation, when changing pallets, the entire pallet of products is placed on the support platform 104. Then, the electric push rod 302 drives the two clamping plates 3 to move closer together. After the two clamping plates 3 move closer, they are supported on the hollow chamber 2 by the reinforcing plate 301, increasing the clamping effect of the clamping plates 3. After the clamping plates 3 clamp the entire pallet of products, the entire pallet of products is securely held. Then, the hydraulic cylinder 102 is activated, driving the piston rod 103 to descend, which in turn lowers the support platform 104. After the support platform 104 descends, the electric push rod 402 is activated. 2. The electric push rod 402 drives the push plate 401. Under the push of the push plate 401, the pallet is pushed away from the support platform 104. Then, the electric push rod 402 is activated to drive the push plate 401 back to contact the fixed plate 4. The pallet to be replaced is then placed on the support platform 104 and set to lower the entire pallet. Then, the hydraulic cylinder 102 is activated to drive the piston rod 103 to rise and support the entire pallet. The electric push rod 302 is then activated to drive the clamping plate 3 away from the entire pallet. The entire pallet is now supported on the pallet and can be removed by a forklift.
