Description

[Detailed Description of the Invention] (Industrial field of application) The present invention takes out a tile row arranged in a rectangular shape in a predetermined number vertically and horizontally from a tile case conveyed by a conveyor and places it on a belt conveyor. The present invention relates to a tile takeout device.

(Prior Art) In general, a tile take-out device of this type has a first conveyor that conveys a box of tiles that are stacked in a rectangular row and a predetermined number of tile rows arranged vertically and horizontally, and a tile row is placed in each column. It is equipped with a tile adsorbing means that reciprocates by a vertical movement and a horizontal movement between a second conveyor composed of a plurality of belt conveyors arranged in parallel to each other to be conveyed by the first conveyor. The tile row is adsorbed by the tile adsorbing means from the tile case and is taken out and transferred to the second conveyor.

(Problems to be Solved by the Invention) By the way, as shown in FIG. 4, tiles T, which are arranged in a square with 6 columns in length and 3 columns in width, are stacked and packed in a box in the case 1 during transportation. The position of each tile T is displaced due to the vibration during transfer by the first conveyor or the first conveyor, and the rows and columns are not aligned.

In the above-mentioned conventional tile take-out device, the tile row that has been destroyed by vibration is taken out from the tile case 1 as it is and directly transferred to the second conveyor, so that the vertical row of tiles is placed on each belt conveyor of the second conveyor without being aligned. Will be. Therefore, the tiles are likely to fall off when placed on the belt conveyor, or the tiles are likely to fall out of balance during transportation. In addition, if the columns of tiles are not aligned, it is inconvenient to handle the tiles in the next step, which is mechanized for labor saving.

In view of such problems, an object of the present invention is to provide a tile take-out device which can be placed on a belt conveyor in a state where columns of tiles are aligned.

(Means for Solving the Problems) In order to achieve the above object, the present invention is to convey a first conveyor for conveying tile cases in which rectangular tile rows are stacked and packed in a box and the tile rows are placed in every column and conveyed. In order to move the tile rows from the tile case to the second conveyor by reciprocating by vertical movement and horizontal movement between the second conveyor composed of a plurality of belt conveyors arranged in parallel with each other In the apparatus, a plurality of alignment stands having the same width as the tile and having the tile rows placed in every column are arranged in parallel between the first conveyor and the second conveyor so as to be movable both inward and outward. Then, an aligning stopper for aligning the columns of the tiles is provided at the outer end of the outermost aligning stand, and the outermost aligning stand is connected to the actuator. When the aligning bases are driven by the actuator to move inward, the adjacent aligning bases are closely contacted with each other, and when moving outwardly, the aligning bases are separated from each other and the aligning bases are adjacent to each other so as to face the belt conveyors. The aligning bases are connected to each other so that they can be separated from each other, and the tile adsorbing means reciprocates between the first conveyor and the aligning base by a vertical movement and a horizontal motion to reciprocate the tile rows from the tile case for each column. The first tile adsorbing means mounted on each alignment table and the reciprocating movement between the alignment table and the second conveyor by the vertical movement and the horizontal movement to reciprocally move the tile columns from the alignment table to the same alignment table. The second tile adsorbing means for transferring onto the belt conveyor is provided.

(Operation and Effect of the Invention) According to the above configuration, the tile rows are taken out by the first tile adsorbing means from the tile case conveyed by the first conveyor, and are set at positions facing the belt conveyor. The tiles are transferred to the alignment table in columns, and then the actuator moves the outermost alignment table inward to bring the adjacent alignment tables into close contact with each other. As a result, the tiles on the outermost aligning table are pushed inward by the aligning stopper, so that the tiles on each aligning table also come into close contact with each other, and as a result, the columns of tiles are aligned in a straight line. It Then, when the actuator moves the outermost aligning table outward, the inner aligning table also moves outward and the adjacent aligning tables are separated from each other, and each aligning table faces the corresponding belt conveyor. Therefore, if the second tile adsorbing means transfers the columns of tiles from the respective aligning stands to the start ends of the corresponding belt conveyors, the columns of tiles are placed on the belt conveyor in a linear alignment.

As described above, according to the present invention, the columns of tiles taken out from the tile case are once linearly aligned and then transferred to the corresponding belt conveyors, so that the tiles are surely placed on the belt conveyor and The tile can be prevented from falling, and the tile can be easily handled in the mechanized next step.
