Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seal plate assembling device for assembling a seal plate such as a gasket to a member to be assembled such as a cylinder block of an engine.

(Prior art) Generally, at a station where a large number of plates are stacked and placed, the suction means of an industrial robot picks up the top plate one by one and transports it to an assembly station where it is assembled onto a workpiece. A similar method is known (see, for example, Japanese Patent Laid-Open No. 60780586).

By the way, in the case of engine gaskets, oil is applied to their surfaces, and if they are piled up as they are, the gaskets will stick to each other and be difficult to separate, so they are sometimes stacked with release paper on every other gasket. In this case, when the gasket is picked up by the suction means, a number of layers of release paper will also follow, and it is necessary for the operator to separately remove this release paper.

(Problem to be Solved by the Invention) The problem to be solved by the present invention is to solve the following problem: When seal plates are placed in a stacked state through an intermediate material such as two series of release papers,
Seal plate 1 allows you to assemble the seal plate onto the workpiece while automatically removing intermediate materials one by one.
Our purpose is to provide assembly equipment.

(Means for Solving the Problems) The seal plate 1 and assembly device of the present invention has a seal plate mounting position where seal plates are placed in a stacked state via an intermediate plate, and a seal plate mounting position where the seal plates are assembled to a workpiece. The movable part set is provided with a movable part set that can be moved between three positions: a position where the seal plate assembly can be removed, and an intermediate phase removal position where the intermediate phase is removed. 1 adsorption means, a second adsorption means for adsorbing the intermediate phase, and an air blowing means for blowing air against the intermediate material, and at the seal plate mounting position, part 1 is provided. Then, the second adsorption means is operated to adsorb the seal plate 1 and the intermediate phase in contact with the lower surface thereof, and the air blow means is operated at the intermediate profit removal position described in 1 to remove the intermediate phase. A control means is provided for controlling the first and second suction means and the air flow means so as to stop the operation of the first suction means at the seal plate 1/assembly position and assemble the seal plate onto the workpiece. It is characterized by

(Function) In the device described in "Seal Plate 1/Group A", the seal plate 1 and the intermediate portion below it are used by the first and second suction means],
Since I is actively picked up, the intermediate 4] will not remain attached to the seal plate below. and,
In removing the intermediate key, the operation of the second suction means is not only stopped, but also the air blowing means is activated to blow out air into the medium, so that the removal of this intermediate phase is ensured. Become.

(Effects of the Invention) Therefore, according to the present invention, from a structure in which the seal plates are placed in a stacked state with an interlayer interposed therebetween, the two most parts of the seal plate and the intermediate material thereunder are removed. It is possible to reliably remove only the intermediate phase before assembling the seal plate to the workpiece, eliminating the need for manual labor by the operator to remove the intermediate phase, improving the efficiency of seal plate 1 and silk fabric work. In addition, since air blowing is used to remove this intermediate material, there is no need to separately grasp and peel off the intermediate phase with, for example, a robot hand, and the structure of the intermediate phase removal means is also simplified.
