Pallet-free off-line stacking device

Abstract

The invention discloses a pallet-free off-line stacking device. The pallet-free off-line stacking device comprises a pallet returning machine, a primary brick push mechanism, a primary brick receivingplatform, a secondary brick push mechanism, a secondary brick receiving platform, a third brick push mechanism, a third brick receiving platform, a fully-automatic green brick stacking machine and apiled brick conveyor. By means of the primary brick push mechanism, bricks on each single layer can be pushed from the pallet returning machine to the primary brick receiving platform. By means of thesecondary brick push mechanism, the bricks on each single layer can be pushed from the primary brick receiving platform to the secondary brick receiving platform. By means of the third brick push mechanism, the bricks on each single layer can be pushed from the secondary brick receiving platform to the third brick receiving platform. By means of the fully-automatic green brick stacking machine, the bricks on each single layer can be clamped and delivered from the third brick receiving platform to the piled brick conveyor. The third brick push mechanism comprises two movable push block platesand multiple third fixing push plates, wherein the movable push block plates are used for pushing the bricks, and the third fixing push plates are used for achieving hole reservation operation of thebricks on each single layer. The pallet-free off-line stacking device is good in operation stability, reliable in stacking process, high in locating precision and capable of automatically stacking thebricks into piled bricks with lifting holes.

Description

technical field [0001] The invention belongs to the field of building material palletizing equipment, and in particular relates to a pallet-free off-line palletizing device. Background technique [0002] At present, in the field of building materials production in our country, when transporting brick stacks, most of them bundle the brick stacks and the pallet at the bottom into a whole, and use a forklift to insert them into the through holes of the pallet to realize the transportation of the brick stacks. Brick stacks will occupy a large number of pallets. After the brick stacks are shipped out of the product factory, due to the limitations of loading and unloading on the construction site, construction and other factors, the recycling cycle of the pallets is long, and the pallets are easily damaged, resulting in a serious shortage of pallet resources. Waste, contrary to the concept of cost saving, low-carbon and environmental protection, and the existing pallet-less brick ...

AI Technical Summary

Problems solved by technology

[0003] Most domestic manufacturers use pallets for bundled transportation when transporting brick stacks, and some manufacturers use pallet-free bundled transportation methods, but the middle lifting holes can only be manually placed to place vacant positions, and then stacked into a whole stack, and then bundled and packaged , which not only greatly affects production efficiency, but also wastes human resources. There are problems in the three palletizing methods widely used at present: low efficiency of manual palletizing, high personnel cost and unstable brick stacking due to manual errors; automatic palletizing Mechanical palletizing, most of them cannot be completely and automatically stacked into brick stacks with lifting holes, and a vacant position needs to be manually reserved at the lifting holes of the stacking, and there are devices that can be completely and automatically stacked into bricks with lifting holes The principle mechanism is different from that of the present invention; intelligent robot arm stacking, currently there is no device that can stack bricks with lifting holes

The stacking process involved in this invention patent is suitable for relatively large concrete blocks. Due to the single brick pushing mechanism, the brick layer cannot be pushed by default, and the bricks cannot be automatically stacked into brick stacks with lifting holes. The current fully automatic stacking machine has the function of stacking by rotating 90 degrees, and the block rotation process in this stacking process is no longer necessary
