Description

Technical Field

[0001] This utility model relates to a transfer device, specifically a pallet transfer device for demolding concrete bricks. Background Technology

[0002] Concrete bricks are produced by casting or pressing using pallets as carriers. After casting or pressing, the bricks need to be demolded to separate them from the pallets, allowing the pallets to be reused. Patent application CN208560797U discloses a steel pallet buffer device for a bricklaying production line, which includes a buffer conveyor on one side of the pallet conveyor line and a palletizing unit mounted above the buffer conveyor and the pallet conveyor line. The palletizing unit transfers steel pallets between the working positions of the buffer conveyor and the pallet conveyor line using magnetic attraction. When the production line starts or the main machine stops production, the buffer device of this utility model can put pre-stored steel pallets onto the production line or transfer and pre-store steel pallets on the production line, eliminating the need for manual handling. This avoids situations where bricks cannot be removed from the curing kiln when the main machine is not producing or is undergoing maintenance and repair, which may affect delivery. Furthermore, when the plate is being suctioned, the connecting seat moves upward and the guide column ensures the straightness of the upward movement of the connecting seat, ensuring reliable contact between the electromagnet and the steel plate. This avoids failure to pick up the plate or damage to the equipment due to steel plate size deviation or detection error.

[0003] The aforementioned buffer device can transfer the pallet, but it does so by magnetically fixing the steel pallet with electromagnetic force. However, during use, the steel pallet is easily corroded by water and alkaline raw materials during the concrete brick production process, resulting in an uneven surface and consequently uneven bricks, which can affect product quality. A better option is to use plastic pallets made of engineering plastics as the carrier, but since plastics are generally non-magnetic, they are difficult to transfer magnetically. Therefore, it is necessary to redesign a pallet transfer device for concrete brick demolding to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a pallet transfer device with a simple structure that can easily lift and transfer plastic pallets and circulate concrete bricks for demolding.

[0005] The technical solution of this utility model is:

[0006] A pallet transfer device for demolding concrete bricks comprises a lifting mechanism, a transition conveyor chain, a demolding conveyor chain, and rollers. The device is characterized in that: a transition conveyor chain is provided on the lifting mechanism, a demolding conveyor chain is provided at one end of the transition conveyor chain, and multiple rollers are provided at intervals at the other end of the transition conveyor chain.

[0007] The lifting mechanism consists of an assembly frame, a rotating shaft, a lifting motor, a lifting frame, lifting sprockets, and a lifting chain. The rotating shaft is movably mounted on the assembly frame via bearing seats. A lifting motor is installed on the assembly frame on one side of the rotating shaft, and the output shaft of the lifting motor is connected to the rotating shaft via a chain and sprockets. A lifting frame is installed on the assembly frame below the rotating shaft, and lifting sprockets are respectively installed on the two ends of the rotating shaft and on the assembly frames below the two ends of the lifting frame. A lifting chain is connected to the lifting frame, and the lifting chain passes through the lifting sprockets at the ends of the rotating shaft and the lifting sprockets below the lifting frame. The lifting frame is fixedly connected to the frame of the transition conveyor chain.

[0008] The lifting frame is U-shaped, and slide rails are respectively provided on the assembly frames on both outer sides of the lifting frame; multiple grooved wheels are respectively provided at both ends of the lifting frame, and the grooved wheels are slidably connected to the slide rails.

[0009] A baffle is provided on the demolding conveyor frame on one side of the transition conveyor chain.

[0010] The height of the bottom edge of the baffle relative to the demolding conveyor chain is between the thickness of the pallet and the thickness of the concrete brick.

[0011] The beneficial effects of this utility model are as follows:

[0012] This concrete brick demolding pallet transfer device has a simple structure. It uses a lifting mechanism to raise and lower a transition conveyor chain, which in turn raises and lowers the pallets. The raised and lowered transition conveyor chain facilitates the convenient transfer of the demolded pallets from a higher position to a lower position on the idler rollers. Because the pallets are raised and lowered via the transition conveyor chain, it can handle both raising and lowering and transferring plastic pallets. Furthermore, it can stack multiple plastic pallets together for transfer at once, effectively improving transfer efficiency and facilitating forklift transfer of stacked pallets from the idler rollers. This solves the problem that existing buffer devices can only transfer steel pallets and not plastic pallets. Attached Figure Description

[0019] This concrete brick demolding pallet transfer device consists of a lifting mechanism, a transition conveyor chain 1, a demolding conveyor chain 2, and idler rollers 3. The lifting mechanism is equipped with the transition conveyor chain 1, which is used to raise and lower the pallet on the transition conveyor chain 1. The demolding conveyor chain 2 is located at one end of the transition conveyor chain 1, transferring the demolded pallet onto the transition conveyor chain 1. Multiple idler rollers 3 are spaced apart at the other end of the transition conveyor chain 1. The gaps between the idler rollers 3 facilitate forklift handling of the pallet, and the rolling motion of the idler rollers 3 reduces friction during transfer, minimizing pallet wear. Because the transition conveyor chain 1 supports the pallet, it can lift and transfer any pallet, including those made of steel and plastic, thus enabling the transfer of the pallet from the demolding conveyor chain 2 to the idler rollers 3. When receiving pallets via the transition conveyor chain 1, multiple pallets can be supported at once, allowing the pallets to be stacked on the transition conveyor chain 1. This enables the pallets to be transported in one go, facilitating the simultaneous transfer of multiple pallets by the forklift on the roller 3.

[0020] The lifting mechanism consists of an assembly frame 4, a rotating shaft 5, a lifting motor 6, a lifting frame 7, lifting sprockets 8, and a lifting chain 9. The rotating shaft 5 is movably mounted on the assembly frame 4 via bearing seats. The lifting motor 6 (servo motor) is mounted on one side of the assembly frame 4, and its output shaft is connected to the rotating shaft 5 via a chain and sprockets. The lifting frame 7 is mounted on the assembly frame 4 below the rotating shaft 5. Lifting sprockets 8 are mounted on both ends of the rotating shaft 5 and on the assembly frame 4 below both ends of the lifting frame 7. The lifting chain 9 is connected to the lifting frame 7, passing over the lifting sprockets 8 at the ends of the rotating shaft 5 and the lifting sprockets 8 below the lifting frame 7. The lifting frame 7 is fixedly connected to the frame of the transition conveyor chain 1. The function of the lifting motor 6 is to drive the rotating shaft 5 to rotate, which in turn drives the lifting sprockets 8 at both ends of the rotating shaft 5 to rotate. The rotating lifting sprockets 8 drive the lifting chain 9 to move, thereby causing the lifting frame 7 to rise and fall. This, in turn, causes the transition conveyor chain 1 to rise and fall. Since the rotating shaft 5 drives the lifting sprockets 8 at both ends of the rotating shaft 5 to rotate synchronously during the rotation process, it can drive the lifting chains 9 at both ends of the rotating shaft 5 to move synchronously. This can drive the lifting frame 7 to lift synchronously, ensuring that the lifting process is not prone to deviation.

[0021] The lifting frame 7 is U-shaped, and slide rails 10 are respectively provided on the mounting brackets 4 on both outer sides of the lifting frame 7; multiple grooved wheels 11 are respectively provided on both ends of the lifting frame 7, and the grooved wheels 11 are slidably connected to the slide rails 10. The function of the grooved wheels 11 is to further restrict the lifting frame 7 by cooperating with the slide rails 10, so that the lifting frame 7 can only move up and down, and is not easy to deviate in the horizontal direction, thus further ensuring the stability during the lifting process.

[0022] A baffle 12 is installed on the demolding conveyor 2 frame on one side of the transition conveyor chain 1. The bottom edge of the baffle 12 is positioned between the thickness of the pallet and the thickness of the concrete brick relative to the demolding conveyor chain 2. This means that the bottom edge of the baffle 12, relative to the demolding conveyor chain 2, only allows the pallet to pass through, but not the concrete brick. The function of the baffle 12 is to block the concrete brick while allowing the pallet to pass through, preventing the concrete brick from being conveyed outwards along with the pallet. This ensures that there are no foreign objects between stacked pallets, guarantees the stability of the pallets when stacked, and facilitates pallet transfer.

[0023] When the concrete brick demolding pallet transfer device is in operation, the transition conveyor chain 1 is raised to be level with the demolding conveyor chain 2. Specifically, the lifting motor 6 is started, and the lifting motor 6 drives the transition conveyor chain 1 upward through the rotating shaft 5, lifting sprocket 8, lifting chain 9, and lifting frame 7 in sequence. After the transition conveyor chain 1 reaches its position, the pallet is demolded on the demolding conveyor chain 2, and the demolding conveyor chain 2 drives the pallet through the bottom of the baffle 12 and transfers it onto the transition conveyor chain 1. After each pallet is transferred onto the transition conveyor chain 1, the transition conveyor chain 1 descends by the thickness of one pallet, and the pallets are stacked during the next transfer. After multiple pallets are stacked, the lifting motor 6 is started, driving the transition conveyor chain 1 downward, making the transition conveyor chain 1 level with the roller 3, and the conveyor chain 1 is started to transfer the pallets onto the roller 3. After the pallets are transferred onto the roller 3, a forklift is used to promptly transfer the pallets from the roller 3 to the next process.

[0024] This concrete brick demolding pallet transfer device has a simple structure. It uses a lifting mechanism to raise and lower the transition conveyor chain 1, thereby raising and lowering the pallet. The raised and lowered transition conveyor chain 1 facilitates the transfer of the demolded pallet from the higher demolding conveyor chain 2 to the lower idler roller 3. Since the pallet is raised and lowered after being received by the transition conveyor chain 1, it can lift and transfer plastic pallets. Furthermore, it can stack multiple plastic pallets together for transfer at once, effectively improving transfer efficiency and facilitating forklift transfer of stacked pallets from the idler rollers. This solves the problem that existing buffer devices can only transfer steel pallets and not plastic pallets.
