Abstract

PURPOSE:To accurately narrow each interspace between tile base themselves after performing suction of these tile bases positively and transferring them onto a loading position, by installing suction cups of the same number as tile bases in a way of making one piece at one end unshiftable and other more than two pieces shaftable the other way. CONSTITUTION:While a moving body 3 is moved to the side of an unloading position, at each suction unit 5, a position rod 26 of an air cylinder 25 is contracted whereby an outer suction box 6c is attracted to the central side. At the beginning, a suction box 6b is pressed via a compression coil spring 31, and attracted to the central side together with the outer suction box 6b. At a spot where a supporter 18 of the suction box 6b collides with a stopper 35, the intermediate suction box 6b is kept at a position corresponding to a tile base (a) of an intermediate row in the unloading position. Afterward, the suction box 6c alone is further attracted while elastically contracting the compression coil spring 31, thus a row of the tile bases (a) of each set, and each interspace among these tile bases (a) is narrowed.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is applicable to cases where a tile base formed by a press is transported to a glazing position in the next process, or when a tile base is packed in a sagger for firing. The present invention relates to a device that transfers tile blanks supplied to a loading position with a certain gap between them to a loading/unloading position by narrowing the gap between the tile blanks.

Conventional Techniques - and Problems to be Solved by the Invention In the tile manufacturing process, the tile base formed by a press is placed on a conveyor and transported to the glazing position for the next process. When press forming, a gap of about 10m+ is required between the tile bases to ensure the strength of the mold, and the tile bases are transported with a gap between them, but at the glazing position where the glaze is sprayed, In order to reduce loss of glaze, it is preferable to transport the tiles with the gaps between the tiles closed.

Therefore, in the past, the gaps in the conveyance direction were closed by stopping the tile bases formed by a press and being conveyed sequentially by a conveyor against a stopper provided at the end position of the conveyor.

Generally, the method used is to align the tiles by closing the gap in the direction perpendicular to the conveyance direction using a guide provided on the conveyor, and then lift the aligned tile bases with a transfer device equipped with a suction cup and transfer them onto the conveyor at the glazing position. Tag.

In particular, when closing the gap in the direction perpendicular to the conveyance direction, the tile base may rotate due to friction with the guide.

The tile bases may press against each other and overlap, causing the tile base to crack when the suction cup of the transfer device is pressed, or excessive load being applied to the support of the suction cup, causing failure. Means for Solving the Problems The tile substrate alignment and transfer device of the present invention has been completed in view of the above points, and at least three tile substrates are arranged in one direction. A movable body that reciprocates between a loading position where the tile blanks are supplied one row at a time with a certain gap between the tiles and a loading/unloading position where the tile blanks in the first row are transferred by narrowing the gap between the tile blanks. , Attach the same number of suction cups as the tile bases in a row in the parallel direction of the tile bases, one end of which is immovable, and the other two or more suction cups movable in the parallel direction.

Among the movable suction cups, the suction cup at the other end located farthest from the immovable suction cup is placed at the loading position and at the loading/unloading position. an elastic body that always urges the movable suction cup disposed between the suction cups at both ends in the direction of the immovable suction cup at the one end; a stopper that abuts the middle suction cup with a bias and holds it at a position corresponding to the middle tile base of the one row of tile bases at the loading/unloading position; As the suction cup moves to the unloading position, the suction cup is moved to a position corresponding to the tile base in the middle of one row of tile bases at the unloading position against the bias of the elastic body. The structure includes an engaging member that engages with the holder.

Functions and Effects of the Invention The present invention has the above-mentioned configuration. First, when the suction cup at the other end that is farthest from the immovable suction cup is moved to the stroke end in the direction away from the immovable suction cup using 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 one row of tile bases at the unloading position, and the intermediate suction cup is pressed against the engagement member by the elasticity of the elastic body. The suckers are positioned at positions corresponding to the tile blanks, and each suction cup takes a position corresponding to a row of tile blanks supplied to the unloading position.

When the movable body is moved to the unloading position in this state, each suction cup is pressed against each tile base and adsorbs the tile base,
Next, after the movable body moves to the loading/unloading position and the tile base leaves the loading/unloading position, until it reaches the loading/unloading position, if the suction cup at the other end is pulled toward the immovable suction cup by the drive device. ,
At first, the middle suction cup is pushed through the elastic body and drawn together with the other end of the suction cup toward the immovable suction cup. On the way, when the middle suction cup hits the stopper, the middle suction cup is loaded and unloaded. After the middle suction cup hits the stopper, only the other end of the suction cup is pulled while the elastic body is elastically contracted, and the other end of the suction cup cannot be moved. When it reaches the stroke end in the direction of approaching the suction cup, it is positioned at a position corresponding to the tile substrate at the other end of the loading/unloading position, and when the suction force of the suction cup is released when the moving body moves to the loading/unloading position, 1 The rows of tile blanks are transferred to the loading/unloading position in a state where they are aligned with narrowed gaps between the tile blanks.

After the tile base is transferred and while the movable body is moving toward the unloading position, the drive device pushes the suction cup at the other end in the direction away from the immovable suction cup.

Due to the elasticity of the elastic body, only the suction cup at the other end moves while keeping the intermediate suction cup pressed against the stopper, and when the engaging member engages with the intermediate suction cup on the way, the intermediate suction cup is pulled together, and the suction cup at the other end moves. reaches the end of the stroke in the direction away from the immovable suction cup, the suction cup at the other end and the intermediate suction cup correspond to the tile substrate at the other end and the intermediate tile substrate of the row of tile bodies at the unloading position. returned to position.

In this way, in the present invention, the tile bases supplied with a certain gap at the unloading position are sucked by suction cups, and the gap between the tile bases is narrowed while moving to the unloading position. After reliably adsorbing the tile substrates, it is possible to accurately narrow the gap between the tile substrates and transfer them to the loading/unloading position.In addition, with a single drive device, it is possible to move the tile substrates to the farthest suction cup from the immovable suction cup. Since the structure allows the device to move between the unloading position and the unloading position together with the intermediate suction cup, there is an effect that the device can be made compact and lightweight.
