Description

TECHNICAL FIELD OF THE INVENTION The present invention is applicable to the case where a tile base formed by a press is conveyed to a glazed position in the next step, or when the tile base is packed in a box for firing. The present invention relates to a device for transferring a tile base material supplied at a loading position with a certain gap to a loading position by narrowing the gap between the tile base materials.

Problems to be Solved by Conventional Techniques and Inventions In the tile manufacturing process, the tile base formed by pressing is placed on a conveyor and conveyed to the glazed position in the next step. Usually, the tile base is pressed. When molding, a gap of about 10 mm is required between the tile bases from the viewpoint of the strength of the mold, and the tile bases are transported with a gap, but at the glaze position where the glaze is sprayed, the glaze is In order to reduce the loss of the tile base, it is preferable to fill the gaps between the tile base materials and convey the tile base materials.

Therefore, conventionally, the tile base that has been shaped by a press and sequentially conveyed by a conveyor is stopped by applying it to a stopper provided at the end position of the conveyor to close the gap in the conveyance direction and A method was generally adopted in which a guide provided was used to fill the gap in the direction perpendicular to the conveying direction and aligned, and the aligned tile base material was lifted by a transfer device equipped with a suction cup and transferred onto the conveyor at the glaze position. Especially when closing the gap in the direction perpendicular to the transport direction,
The tile base may rotate due to friction with the guide, or the tile bases may be pressed against each other, causing the tile bases to overlap with each other.When the suction cups of the transfer device are pressed, the tile bases are cracked, or the suction cups are sucked. An excessive load may be applied to the support part of the and may cause a malfunction.

Means for Solving the Problems The tile base aligning and transferring apparatus of the present invention has been completed in view of the above points, and at least three tile bases are spaced at regular intervals in one direction. The same number of tile foundations as the moving bodies that reciprocate between the unloading position where the tile foundations in one row are supplied and the unloading position where the tile foundations in one row are transferred with a narrow space between the tile bodies are loaded. Of the suction cups which can be attached and moved, the suction cups are arranged in a row in the parallel direction of the tile base, and one of the ends is immovable and the other two or more are movable in the parallel direction, respectively. The suction cup at the other end arranged farthest from the immovable suction cup is reciprocally driven by a distance corresponding to a difference in distance between the tile bases at both ends of the one row of tile bases at the loading position and the unloading position. Moveable between the drive unit and the suction cups at both ends Elastic body which is attached to a rod fixed to the suction cup at the other end and which always urges in the direction of the immovable suction cup, which penetrates through the above-mentioned suction cup, and the attachment of the elastic body formed at the tip of the rod. The engaging portion that holds the intermediate suction cup by force to hold it at a position corresponding to the intermediate tile base of the row of tile bases at the loading position and the immovable suction cup fixed to the intermediate suction cup at the other end. To move to a position corresponding to the tile base in the middle of one row of tile bases at the unloading position against the urging of the elastic body with the movement of the sucker to the unloading position. A stopper is provided to be engaged with the intermediate suction cup.

Action and Effect of the Invention The present invention has the above-described configuration. First, when the suction cup at the other end farthest from the immovable suction cup is moved to the stroke end in the direction away from the immovable suction cup by the drive device, the suction cup at the other end Is positioned at a position corresponding to the tile base at the other end of the row of tile bases at the loading position, and the intermediate suction cup is pressed against the engaging member by the elastic force of the elastic body, and The suction cups are positioned at positions corresponding to the tile bases, and each suction cup takes a position corresponding to each row of the tile bases supplied to the shipping position.

When the moving body is moved to the unloading position in such a state, each suction cup is pressed against each tile base material to adsorb the tile base material, and then the moving body moves to the unloading position side to load the tile base material. After leaving the position and before reaching the loading position,
When the suction cup at the other end is pulled to the immovable suction cup side by the drive device, the intermediate suction cup is first pushed by the elastic body and is pulled together with the suction cup at the other end to the immovable suction cup side. After the intermediate suction cup hits the stopper and the intermediate suction cup is held at the position corresponding to the intermediate tile base in the loading / unloading position, and the intermediate suction cup hits the stopper, the elastic body is compressed and the other end is pressed. When only the suction cup of the other end is drawn and the suction end of the other end reaches the stroke end in the direction approaching the immovable suction cup, it is positioned at the position corresponding to the tile base at the other end in the unloading position, and the moving body is stacked. When the suction force of the suction cups is released at the time of moving to the descending position, the tile bases in one row are transferred to the unloading position in a state where the tile bases are aligned with the gap between them narrowed.

After the tile base is transferred, while the moving body moves to the loading position side, if the driving device pushes the suction cup at the other end away from the immovable suction cup, the elasticity of the elastic body causes the intermediate When the suction cup at the other end moves while the suction cup is pressed against the stopper, and the engaging member engages with the intermediate suction cup midway, the intermediate suction cup is pulled together and the other suction cup moves away from the immovable suction cup. When the stroke end in the direction is reached, the suction cups at the other end and the suction cups at the middle are returned to the positions corresponding to the tile bases at the other end and the tile bases at the middle of the row of tile bases at the shipping position.

As described above, in the present invention, since the tile base material supplied with a certain gap at the loading position is sucked by the suction cup, the gap between the tile base materials is narrowed while moving to the loading / unloading position. After surely adsorbing the tile base, the gap between the tile bases can be accurately narrowed and the tile base can be transferred to the loading / unloading position, and the suction cup that is farthest from the immovable suction cup can be driven by one drive device. Since the intermediate suction cup and the intermediate suction cup are configured to be movable between the loading position and the unloading position, the device can be made compact and lightweight.
