[Prior Art]

 Conventionally, as shown in FIG. 4, an adsorption device for adsorbing and transferring a large number of tiles of various sizes is made of rubber and integrally molded, and is located above a conical suction cup b having a through hole a in its central portion. A suction chamber d having a spherical inner space having a valve opening c communicating with a vacuum pump at the upper part is formed, and an adsorber f for opening and closing the valve opening c is formed by a spherical body e housed in the suction chamber d. Many suction boxes g are found, but in the case of this adsorber f, however, dirt due to foreign substances adhering to the surface of the spherical body e and the shape defect of the valve opening c (integrated molding). In addition, since the valve port c is formed inside, it cannot be inspected.) Therefore, there is a defect that a sealing failure occurs with the sphere e.

Therefore, the inside of the suction box g is divided into an arbitrary number according to the tiles, and the valve j is provided for each of the block chambers h to eliminate the above-mentioned drawbacks. As the number of block chambers h increases to several hundreds or more, the number of valves j to be used also increases, resulting in an extremely high cost, and electrical control that combines the operation and non-operation of the adsorber f depending on the tile is complicated. Had the drawback of becoming.
