Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a component supply device, which is mainly intended to properly and temporarily retain a component in a temporary stop chamber. What is projected to the outside is the target of supply.

(B) Conventional Technology The conventional technology will be described with reference to FIGS. 7 and 8. FIG. 7 shows an example of handling a projection nut 2 having a projection 1 for welding. The protrusion 1 projects outward in the lower part of the component, that is, in a direction away from the center line of the nut 2. The supply pipe 4 having the supply passage 3 of the nut 2 and the guide pipe 6 of the supply rod 5 are arranged in a substantially orthogonal positional relationship, and a stop plate 7 is installed at the right side position of the supply passage 3. The temporary stop chamber 8 is formed by the member arrangement as described above. The temporary stop chamber 8 is opened downward, one side is the opening of the supply passage 3, the other side is the installation of the stop plate 7, and the upper side is the upper wall surface 9. In the case of FIG. 7,
The entire stop plate 7 is made of magnets (permanent magnets) 10.

In FIG. 8, the component is a nut 12 with a flange 11, and a magnet 10 is incorporated below the stop plate 7. The flange 11 projects outward at the bottom of the part, ie away from the centerline of the nut 12. The other structure is the same as that of FIG. In both figures
Reference numeral 13 is a guide pin fixed to the tip of the supply rod 5.

(C) Problems to be solved by the device In the conventional example as described above, since the components that have passed through the supply passage 3 are directly sucked directly by the magnet 10, the upper part of the temporary stop chamber 8 As shown in the drawing, a gap is formed between the wall surface 9 and the component, which temporarily locks the component in a tilted state. That is, in the case of the projection nut 2, since the entire stop plate 7 is a magnet, the nut 2 is sucked and moved right beside and the protrusion 1 is also protruded laterally as shown in the figure. Inclination occurs, and in the case of the nut 12 with the flange, the inclination due to the flange 11 occurs. If such an inclination occurs, the guide pin 13 of the supply rod and the screw holes of the nuts 2 and 12 do not coincide with each other in the axis line, so that the guide pin 13 does not smoothly enter the screw hole and only the nut comes first. It will be repelled.

(D) Means for Solving the Problem and Its Action The present invention has been provided to solve the above problems, in which parts are temporarily locked in a temporary stop chamber in which the supply passage is open. , A magnet that is mounted in a state where it forms a part of the stop plate of the component, in which the component is delivered by the supply rod, and the protrusion or flange or the like protruding outward from the bottom of the component is the target of supply. Is displaced to the upper wall surface side of the temporary holding chamber, and such a magnet arrangement allows the component to enter the temporary fixing chamber while adhering to the upper wall surface of the temporary fixing chamber, and The protrusion and the flange come into contact with the stop plate and stop while keeping close contact with, thereby preventing the parts from tilting. That is, the component entry as described above is achieved by forming a vector component of the attractive magnetic force having a directivity that lifts the component.

(E) Embodiment In the embodiment shown in FIGS. 1 to 6 below, the seventh embodiment
Members given the same reference numerals as those in FIGS. 8A and 8B have the same functions as those shown in FIGS.

In order to solve the above-mentioned problem, in FIGS. 1 and 2, the magnet 10 is assembled to the stop plate 7 in a state where the magnet 10 forms a part of the stop plate.
It is arranged close to the upper wall surface 9 side. That is, when the nut 2 moves in the temporary stop chamber 8, the nut 2
The nut 2 slides into the upper wall surface 9 so as to approach the upper side (see FIG. 1). In this way, the magnet 10 is displaced toward the upper wall surface 9 so that the nut 2 having moved through the supply passage 3 is given an upward motion component. Therefore, finally, as shown in FIG. 2, the nut 2 is attracted by the magnet 10 in a state where the nut 2 is in close contact with the upper wall surface 9, and at this time, the projection 1 contacts the stop plate 7.

In the case of FIG. 3 and FIG. 4, the supply rod 5 is constituted by a hollow outer shaft 14 and an inner shaft 15 slidably incorporated therein, and at the tip of the inner shaft 15. The magnet 16 is fixed. The outer shaft 14 is preferably made of stainless steel, and a frame-shaped projection 17 as shown in FIG. 4 is provided at the tip of the outer shaft 14. The protrusion 17 is an opening for allowing the nut 2 to pass through.
18 are formed. The approach behavior of the nut 2 is the same as in the case of FIGS. 1 and 2. In the case of the one shown in FIG. 3, when the outer shaft 14 and the inner shaft 15 are integrally advanced and stopped at a predetermined position, then only the inner shaft 15 is retracted to eliminate the magnetic force on the nut 2. The purpose is to remove the nut.

The embodiment shown in FIGS. 5 and 6 has a cylindrical portion 19 and a flange portion 20.
In the case of the component 21 consisting of, the operation is similar to the previous embodiment. This embodiment is intended for a part as shown in FIG. 8, and the position of the magnet 10 is displaced considerably upward from that of FIG. 8 due to the shape of the part, but the displacement shown in FIG. Not not.

It is appropriate to displace the magnet to the upper wall surface side as much as possible in consideration of the relation with the center of gravity of the parts and the posture when traversing the temporary stop chamber.

(F) Effect The present invention is intended for supplying a part having a protrusion or a flange protruding downward to the outside, and is a magnet attached to the stop plate in a state of forming a part of the stop plate of the part. Is displaced toward the upper wall surface, the attractive magnetic force acting on the component that has entered the temporary stop chamber has a directional upward vector component, so the component slides on the upper wall surface. However, when the projection or flange comes into contact with the stop plate and stops, the part is temporarily locked in close contact with the upper wall surface, preventing the part on which the projection or flange for welding is formed from tilting. Can be solved completely.
