In the existing concrete block production process, most of the front-end production process adopts the production process of batching, mixing, forming, and stacking boards with a high degree of mechanization and automation; while the subsequent production process is mostly still manual due to the lack of economical and applicable methods. Mainly. The formed block body and pallets are stacked layer by layer to form a "pallet stack" in which pallets and blocks are stacked alternately, as shown in Figure 4. The pallet stacks on which the blocks are placed are transported to the curing yard by means of transport such as forklift trucks for maintenance. After the concrete blocks are cured, the blocks are manually detected and coded into "block stacks"; at the same time, the pallets are manually collected and sent to the block forming machine for use in remolding.

It can be seen that the existing post-production process of concrete blocks has the following disadvantages: after the blocks are cured, the work of stacking blocks and collecting and transporting pallets must be done manually by workers. This requires a large number of operators, and the labor intensity of the workers is great, and the operation process is also easy to damage the blocks, which is not conducive to improving production efficiency and improving the quality of the concrete blocks.

In view of the above-mentioned shortcomings of the existing concrete block production process, a simple, economical and applicable automatic palletizing equipment for the concrete block production process is needed.

Several pneumatic grippers are installed below for grabbing bricks. This invention patent is only applicable to the hydraulic brick machine, and it is only suitable for clamping specific brick types (such as standard bricks). Therefore, the automatic stacking machine has a narrow application range and cannot meet the needs of most brick factories.

The invention patent with the patent number CN201010559438.5 discloses an automated production process for the rear production process of concrete blocks, that is, an automatic stacking process for concrete blocks. Block process and block stacking process. The stacking process involved in this invention patent is also only suitable for some specific relatively large brick types, and there is no interval rotation process during the stacking process, so that the stacked blocks after stacking are easy to collapse due to external force , and in this invention patent, only the part of the pallet inside the palletizer frame can be utilized, so the utilization rate of the pallet is low.

(16) Push the block onto the brick-connecting platform (22). When the block reaches the center of the brick-connecting platform (22), the proximity sensor at this position will act, and once the block pushing plate (16) returns, and the supporting The board still stays on the pallet return machine (6); [2] Start the supporting plate to return to the hydraulic cylinder (9), and the movable frame (7) continues to move towards the front position of the supporting plate returning machine (6) with the supporting plate. When reaching the supporting plate returning machine (6) front position, The proximity sensor at this position acts, the movable frame (7) stops moving, and the supporting plate slides into the stacker (17); Third, the side push block process: The side push hydraulic cylinder (19) drives the side push plate (21) to push the block from the brick receiving platform (22) onto the turntable (24). When the block reaches the center of the turntable (24), the proximity sensor at this position activates , the side push plate (21) returns; Fourth, block rotation process: After the block reaches the center of the turntable, the turntable (24) rotates 90°; Fifth, the second block pushing process: The second block push plate (8) pushes the block from the turntable (24) to the inner side of the hydraulic clamp (29), and when the block reaches the limit baffle position on the stacking platform (27), the Proximity sensor action, the second push block push plate (8) returns; Sixth, the block stacking process, the steps are as follows: [1] After the second pushing block is completed, the hydraulic lifting platform under the stacking platform (27) rises to a height slightly lower than the pull plate (25) and stops, and at the same time, the hydraulic clamp (29) pulls the block from both sides block clamping; [2] Start the pulling plate hydraulic cylinder (26) to pull the pulling plate (25) out from under the block. When the rear position of the pulling plate (25) is close to the sensor action, the pulling plate (25) stops moving, and then the hydraulic clamp (29 ) slowly unclamps, and the block falls on the pallet (28); [3] Make the hydraulic lifting platform stop after dropping the height of a block, and then the pull plate hydraulic cylinder (26) pulls the pull plate (25) back to the front position; After the above-mentioned one-time stacking action is completed, the concrete block automatic stacking equipment starts the next cycle until the pallet (28) descends on the conveyor chain (30) of the stacker, and the block stacking falls on the stacker ( 31) On the rear position, the stacker (31) starts, and the above-mentioned block stacking is transported to the front position of the stacker (31). 7. The palletizing process of the concrete block automatic palletizing equipment according to claim 6, characterized in that: during the palletizing process, a rotation action is performed every other time.
