A transfer member having a hole and a regulating surface is inserted in a movable state, and an air nozzle hole is provided in the delivery pipe connected to the outlet hole, and a magnet for attracting parts is installed at a position on the delivery side of the nozzle hole. The feature is that the parts are waiting on the regulating surface in advance, and when the transfer member strokes and the through hole matches the inlet hole and the outlet hole, the part is sent through the through hole to the delivery pipe and sent out by the magnet. The parts are stored by suction on the inner surface of the tube, and after the transfer member closes the outlet hole, compressed air is ejected from the air injection hole, and the force of the compressed air causes the parts to be sent out through the delivery tube against the magnetic attraction. Then, the next component is again placed on standby on the regulating surface. According to a second aspect of the present invention, in the first aspect, the air nozzle hole and the magnet are positioned opposite to each other when viewed from the cross-sectional direction of the delivery tube, and the ejected air is blown directly against the component. Claim 3 is a method carried out using the apparatus as claimed in Claim 1, in which a component is placed on standby in advance on a regulating surface, and the component is removed by matching the inlet hole and the outlet hole. The material is passed through the delivery pipe and adsorbed to the inner wall of the pipe by a magnet, and immediately after that, the inlet hole is closed by the regulating surface of the transfer member, and then the parts inside the delivery pipe are blown away by an air jet, and at about the same time, the next The part is then brought onto the restricted surface.

。[0006] Air injection holes 26 are provided in the delivery pipe 17.
A connecting pipe 27 is welded continuously thereto, and an air hose 28' is connected thereto. A magnet 28 is installed at a position closer to the delivery side than the air injection hole 26. The magnet here is a permanent magnet, and is housed in the case 29 and attached to the outer surface of the delivery tube 17. The positional relationship between the magnet 28 and the air nozzle hole 26 when viewed in the component delivery direction is as described above, but the positional relationship when viewed from the cross-sectional direction of the delivery pipe 17 is such that they face each other in the diametrical direction as shown in FIG. ing. Note that a supply hose 30 extending from a parts feeder (not shown) is connected to the inlet pipe 16. Furthermore, it is preferable that the delivery tube 17 be made of a non-magnetic material such as stainless steel to further strengthen the magnetic force acting on the components.

Problems such as those mentioned can definitely be solved. Since air is injected to a place that is temporarily held by a magnet, and the outlet hole is closed when air is injected, the air pressure acts positively on the parts.
The transfer force to the parts can be effectively obtained, and since the injection transfer starts from temporary locking, it is possible to accurately control the supply according to the required timing. Since the positional relationship between the air nozzle hole and the magnet is opposite when viewed from the cross-sectional direction of the delivery pipe, the ejected air hits the parts directly, and the dynamic pressure of the ejected air is effectively applied to the parts. It is effective for powerful yet moderate parts delivery.
