Abstract

PURPOSE:To temporarily hook a part correctly with high reliability via the proper setting of relative positions of a feeding means and a hooking means of parts by integrally arranging them, and moving the feeding means to the correct feed position and the retreat position. CONSTITUTION:If a bolt 4 is fed when an outlet pipe 8 is located at the position of a double-chain line by the action of an air cylinder 13, a shaft section 6 enters a holding hole 16, and a taper section 7 matches an extruding piece 31. The magnetic force of a magnet 19 is applied to the shaft section 6 for temporary hooking. The outlet pipe 8 is moved to the right by the action of the cylinder 13 to the retreat position from a hooking means 2 as shown by a solid line. When means 1, 2, 27 are integrally advanced to the preset positions by a cylinder 32 and stopped, a holding piece 18 is retreated to the left by a cylinder 24, the magnetic force of the magnet 19 to the shaft section 6 practically disappears, and the bolt 4 is dropped and fed to the objective position.

(F) Effects According to the present invention, the feeding means and the locking means are integrally arranged, so that the feeding means can take the normal position and the retreated position when feeding. Therefore, by setting the relative positions of the feeding means and the locking means to be exactly the same, the parts can be temporarily locked with high reliability. Since a retractable magnet is used as the locking means, it is possible to securely lock the parts once, and also to correctly release the temporary lock by retracting the magnet. By attaching the extrusion means to the receiving member, the transfer of the goods is forced, and S loading errors do not occur. It is advantageous to provide a side of the drive so that the member approaches the part.
The locus of movement of the damaged structure can be easily determined, and even in places where there are space constraints, it is possible to use as few paperbacks as possible. Furthermore, by combining the feeding means and the locking means with the advancing and retracting means, the temporarily locked parts can be accurately brought to the receiving member of the other party.
