Description

[Detailed Description of the Invention] [Objective of the Invention] Industrial Field of Application The present invention provides a method for manufacturing bricks, in which the work of loading blanks onto a firing cart before firing and the work of unloading fired products after firing in the firing process are carried out. This invention relates to an automatic brick loading/unloading line system that allows centralized operation at the same work site using a series of mechanical lines.

Conventional technology Conventionally, in the process of manufacturing bricks, operations such as moving, transporting, and placing the molded blank material to the next process were required each time. Due to the high humidity of the white background, please be sure to
Extreme care must be taken to prevent damage to corners, etc.
In addition, relying on manual labor for each of these operations is extremely inefficient and uneconomical, and the operations must always be performed with extreme caution, which limits the improvement in yield.

Problems to be Solved by the Invention In the present invention, the molded blank bricks are piled up in grids on a pallet receiver every 4 to 5 sheets, and then transferred to the firing cart in line, and the fired bricks are placed on the conveyor. By loading and unloading bricks sequentially, we are able to improve the yield, reduce the manufacturing cost of bricks, secure a work area, and centrally manage continuous production status at the same work site. It aims to provide a loading and unloading line system.

[Structure of the invention]

Means for Solving the Problems The present invention has been developed in view of the above points, and in the next step in which the clay extruded by the clay kneading machine is cut into a predetermined length and a predetermined number of pieces by a cutter, a two-stage conveyor is used to cut the clay into pallets. The blanks are transferred in a circular manner to a stacking position, where they are stacked in a grid on a pallet receiver on one of the two-stage conveyors by a stacking device, and the blanks are sequentially arranged on a baking cart that is circulated and transferred together with the receiver. After transferring the firing carts to the firing furnace and firing them, the firing carts are transferred to the loading and unloading position, and the loading and unloading device loads the bricks together with the receivers from the firing cart onto one of the two-stage conveyors. It is an object of the present invention to overcome the above-mentioned drawbacks by providing an automatic brick loading and unloading line system for loading and unloading bricks onto pallets.

Function The present invention stacks a white background formed into a predetermined shape in a lattice on a pallet receiver using a stacking device when the pallets on one of the conveyors that are circulated by a two-stage conveyor are transferred to a stacking position. Next, the white fabric stacked in a lattice is transferred along with the receivers and pallets to the loading position on the baking cart by one of the two-stage conveyors, and is aligned and transferred onto the baking cart together with the receivers. After the transferred firing carts are sequentially carried into the firing furnace and fired, when the firing carts are transferred to the loading/unloading position, the bricks are placed together with the receivers onto the pallet on one of the two-stage conveyors by the loading/unloading device. Continuous operation is handled by transferring and then transporting to the unloading position.
