Tray-free packing method and tray-free packing device of brick stack

Abstract

The invention discloses a tray-free packing method and a tray-free packing device of a brick stack. The tray-free packing device comprises a feeding machine, a clamping and transporting device, a cyclic conveying line, binding machines and a plurality of transfer trays; the feeding machine is arranged on a return track to complete the movement and positioning of a steaming-curing truck, and the return track runs through the clamping and transporting device; the cyclic conveying line is a closed rectangular annular cyclic conveying chain and comprises an empty-tray conveying chain-type conveyor belt, a secondary folding and clamping chain-type conveyor belt, an elevation and pushing mechanism, a primary binding chain-type conveyor belt, a secondary elevation and pushing mechanism, a secondary binding chain-type conveyor belt, a stack unloading chain-type conveyor belt, an empty-tray feeding chain-type conveyor belt and the a tray transportferring device; two binding machines respectively stretches across the primary binding chain-type conveyor belt and the secondary binding chain-type conveyor belt so as to bind the brick stack in the two mutually-vertical directions; and a transportferring tray is horizontally arranged on each station of the cyclic conveying line. Due to the adoption of the device, the production efficiency is greatly improved, and the labor intensity of workers is greatly alleviated.

Description

technical field [0001] The invention relates to the technical field of autoclaved brick stack packaging machinery, in particular to a pallet-free packaging method and device for brick stacks. Background technique [0002] Most of the existing wall bricks in China are loaded and unloaded by finished bricks in bulk, and recently there has been a demand for packaging finished bricks into whole brick stacks for loading and unloading and transportation. Due to the shortcomings of high damage rate, heavy loading and unloading workload, low loading and unloading efficiency, environmental pollution, and large storage space occupied by finished bricks in bulk loading and unloading transportation methods, more and more wall material product companies and construction companies have proposed packaging of finished bricks. The method of loading and unloading and transportation of brick stacks as a whole and the requirements for equipment. [0003] In the existing packaging technology fo...

Problems solved by technology

[0004] 1. The whole bricks are sent to the finished product yard through the fixture for bulk storage, and then the bricks are re-stacked manually to form a brick shape suitable for packaging, and finally the bricks are bundled by a simple manual strapping device to form Finished bricks are packaged into stacks of bricks; the packaging process is backward, the packaging production does not match the brick production line, the labor intensity of the workers is high, and the work efficiency is low;

[0005] 2. Put the bricks on the wooden pallet with a jig and then use manual or strapping equipment to bundle the bricks and the pallet together into a packaged brick. This packaging method requires a wooden pallet for each brick. Although the pallet is envisaged to be recyclable use, but the pallet is easily damaged during transportation and use, and recycling is troublesome, and the recovery rate and intact rate are difficult to guarantee, so the packaging cost of brick stomp is high
