An example of this is the device disclosed in Japanese Patent Publication No. 47-41655, which I invented. Various types of magnets are known in which a component is temporarily held on the sliding surface of a magnet and is pushed out by the advance stroke of the supply rod while sliding on the sliding surface. but,
Here, a case is shown in which a projection nut as shown in FIG. 1 is supplied to a spot welding device.

石であつてもよい。 To explain the component supply device 5, the head body 6 is provided with a temporary fixing chamber 7 that opens downward, and a component supply passage 8 communicates with the temporary fixing chamber 7. This passage is formed by a port 9 opened in the head body 6 and a component supply pipe 10. A magnet 11 is fixed at the front position of the component supply passage 8.
One side thereof serves as a component sliding surface 12 so as to form one inner wall of the temporary fixing chamber 7 . Although the illustrated magnet 11 is a permanent magnet and is fixed to the head body 6 using a bolt 13, it may be an electromagnet instead of a permanent magnet.

係が設定されている。 The supply rod 14 is operated by the forward and backward movement output of an air cylinder 15, and is adapted to slide within a guide tube 16 provided in the head body 6. Since the component 17 to be supplied in the illustrated case is a projection nut, the supply rod 14 is provided with a guide rod 18 that enters into the threaded hole of the nut.
An extrusion surface 19 is provided at the interface between the supply rod 14 and the guide rod 18. In the illustrated state, the nut 17 is attracted to the component sliding surface 12 and is temporarily locked, and the positional relationship of each part is set so that the screw hole of the nut 17 and the supply rod 14 are coaxial. There is.

7, the nut 17 is pushed out while sliding on the component sliding surface 12, and after the nut leaves the component sliding surface 12, it slides on the guide rod 18 and is brought into alignment with the pin 4. 2 in Figure 1
The state shown by the dotted chain line indicates a transition period in which the nut 17 is supplied.

大きく、これによつても摺動面１２に摩耗が発生
する。 In the parts supply device as described above,
Due to the extremely high frequency of use due to mass production, the problem of wear occurs on the sliding surface 12 of the magnet component. This is a phenomenon peculiar to magnets, and when the nut 17 enters the temporary locking chamber 7 after the supply rod 14 has retreated, the nut 17 is significantly accelerated by the attractive force of the magnet 11. Therefore, the impact energy on the magnet 11 becomes extremely large. Moreover, when compressed air is supplied at high speed, rather than when it slides down under its own weight as shown in Figure 1, the magnetic force is added and the impact force becomes even higher. If such a phenomenon is repeated many times, the sliding surface 12 of the component that is hit by the nut will become damaged.
The parts are worn out so that they look like they are depressed. As a result, the flatness of the component sliding surface 12 is impaired, and the temporary locking position of the nut 17 is tilted, causing the nut 17 to be out of coaxiality with the supply rod 14, which may impede correct extrusion by the supply rod 14. Also,
During the transition period of extrusion, the attraction force of the magnet is acting, so the frictional force between the nut and the component sliding surface 12 is considerably large, and this also causes wear on the sliding surface 12.

防止できるのである。 As a means to prevent wear as explained above, it is generally adopted in other technical fields to manufacture only the relevant parts with high-grade materials with excellent wear resistance. In a component supply device such as the one shown in FIG. FIGS. 2 to 5 are embodiments in which such considerations have been taken into consideration, and are shown as single-piece views with the magnet 11 removed from FIG. 1. 2 and 3 show a first embodiment, in which a wear prevention member 20 with excellent wear resistance is embedded in a component sliding surface 12, and the member 20 is formed of a long and thin steel plate. As is clear from both figures, the member 20 is press-fitted into a narrow groove cut into the magnet 11. Since the member 20 must exhibit excellent wear resistance, it is appropriate to use high grade materials such as molybdenum steel, tool steel, and the like.
The buried member 20 continues smoothly with respect to the component sliding surface 12 and is exposed in a linear form on the component sliding surface 12. Preferably, the direction extends in the extrusion direction of the part. The reason why the member 20 extends below the magnet 11 as shown in FIG. 2 is to ensure that the component is guided more reliably and to prevent the sliding resistance from disappearing when the component is separated from the component sliding surface 12. This is to prevent the supply rod 14 from being suddenly accelerated. Since this extended portion is magnetic, sudden changes in sliding resistance can be prevented.

材料を使用するのが適当である。 In the second embodiment shown in FIGS. 4 and 5, a wire rod made of the above-mentioned material is buried as the wear prevention member 21, and appears in the form of a line on the surface. Incidentally, it is appropriate to use a magnetic material for the wear prevention members 20 and 21 in order to prevent the component attraction force from decreasing even in the slightest.

る。 According to the present invention, the buried wear prevention member acts against collisions and sliding of parts, thereby preventing the parts from being temporarily locked in an abnormal position as described above, and allowing normal extrusion of the supply rod. It can be achieved. A particularly important point is that since the wear prevention member appears in a linear form on the sliding surface of the component, it only slightly reduces the area of contact between the component and the magnet, resulting in insufficient adsorption force. It is extremely suitable for this type of parts supply device since it does not have any disadvantages such as causing problems.
