Description

Technical Field

[0001] The invention belongs to the field of aerated concrete product production equipment, and in particular relates to a clamp for sorting aerated concrete blocks. Background Art

[0002] At present, the existing aerated concrete packaging is generally packaged as a whole after leaving the kettle, so there are damaged blocks in the brick stacks transported to the site, but the aerated concrete blocks are priced based on the intact products after being transported to the construction site. At the same time, the damaged products are easy to cause damage to the adjacent blanks when packaged without a pallet. Therefore, the packaging without a pallet requires the damaged products to be sorted before packaging. In the prior art, there is no clamp for sorting blocks. The block sorting generally requires sorting the blocks into three types: intact products, second-class products, and damaged products, and then these three products need to be processed separately. Therefore, the developed sorting clamp also needs to be able to realize the sorting of the three products. Summary of the invention

[0003] The purpose of the present invention is to provide a clamp for sorting aerated concrete blocks, which can clamp and stack the brick group where the damaged blocks are located, put the intact blocks in the brick group in a designated place, stack the second-class blocks on the second-class pallet, discard the damaged blocks, and clamp the pallet to realize the automatic pallet transportation. The clamp of the present invention can be used in multiple links of block sorting, greatly improving the automation degree and sorting efficiency of block sorting, effectively reducing manual participation, and saving labor costs.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a clamp for sorting aerated concrete blocks, comprising a support frame and a plurality of gripper groups arranged on the support frame, each gripper group comprising two symmetrically arranged grippers and a driving mechanism for controlling the opening and closing of the two grippers, at least one of the plurality of gripper groups is a broken block gripper group, and the remaining gripper groups are main gripper groups; the main gripper group is used to clamp a whole group of blocks, and the broken block gripper group is used to clamp broken blocks that cannot be clamped by the main gripper group; the support frame is also provided with a pallet gripper for clamping a pallet.

[0005] The upper ends of the two grippers of the gripper group are hinged to the support frame, and the two ends of the driving mechanism are respectively hinged to the middle parts of the two grippers to achieve the clamping and opening of the grippers.

[0006] The two grippers in the broken building block gripper group are provided with grippers extending oppositely, and the grippers are provided with clamping surfaces. The two grippers can achieve different degrees of closure under the control of the corresponding driving mechanism to clamp the broken building blocks with different degrees of damage.

[0007] The incomplete building block gripper group is arranged at the ends of the plurality of gripper groups, and a patterned anti-skid clamping surface is provided on the gripper head of the incomplete building block gripper group.

[0008] The working stroke of the driving mechanism of the incomplete building block gripper group is longer than that of the driving mechanism in the main gripper group, so as to ensure the gripping of severely damaged building blocks that cannot be gripped by the main gripper group.

[0009] The pallet grippers are provided with two groups, and the two groups of pallet grippers achieve synchronous action through a synchronization mechanism, and the synchronization mechanism is connected to the pallet clamping power mechanism.

[0010] The synchronization mechanism includes a synchronization shaft and a connecting rod mechanism. The synchronization shaft is rotatably mounted on the support frame. The connecting rod mechanism is provided with two groups, which are respectively arranged at both ends of the synchronization shaft. Each group of connecting rod mechanisms includes an adjusting connecting rod and a connecting plate. The connecting plate is fixed to the axial end of the synchronization shaft. One end of the adjusting connecting rod is hinged to the connecting plate, and the other end is hinged to the clamping piece of the adjacent pallet clamp.

[0011] The length of the adjusting link can be adjusted.

[0012] The clamping piece in the pallet clamp is provided with a hook capable of hooking the edge of the pallet.

[0013] The driving mechanism is a linear driving mechanism.

[0014] The beneficial effects of the present invention are as follows: first, the present invention can realize the clamping of a whole set of bricks, the discarding of damaged blocks, the clamping of incomplete blocks adhered to the brick stack, and the clamping of pallets, thereby meeting the requirements of each link in the sorting process, greatly improving the automation degree and sorting efficiency of block sorting, and saving labor costs.

[0015] Second, the multiple gripper groups in the present invention can grip the entire group of blocks where the damaged blocks are located, and process the intact, second-class and damaged aerated concrete blocks separately; or only the second-class and damaged blocks can be gripped and processed separately. The intact and second-class aerated concrete blocks need to be stacked on a pallet, and the pallet gripper can be used to clamp the pallet for transportation.

[0016] Third, since the size of the broken building blocks is smaller than that of the intact building blocks and the shape is irregular, conventional clamps cannot clamp or tighten them. Therefore, the present invention provides a broken building block clamp group, and the two clamps of the clamp group are provided with clamps extending in opposite directions. Under the control of the driving mechanism, the two clamps can achieve different degrees of closure, rather than closure in a single position, so broken building blocks of different sizes can be clamped and clamped.

[0017] Fourthly, in the present invention, the synchronous action of the two groups of pallet grippers is achieved through a synchronous mechanism, the structure is simple and compact, and the clamping pieces of the pallet grippers are provided with hooks that can hook the edge of the pallet to prevent the pallet from falling off during transfer.
