DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. The shaft-like component 1 with a flange in this embodiment is for "caulking" and is made of iron in which a circular flange 3 is integrated with a shaft portion 2 having a circular cross section. The shaft portion 2 includes a large diameter portion 4 and a small diameter portion 5. This part 1 is used as a pivot of a hinge as shown in FIG. 7, and arm 6 and 7 made of steel plate are rotatably connected. A recess 9 is formed in the fixed die 8 for caulking, and the flange 3 is fitted into the recess 9 exactly. Then, the hole of the arm 6 matches the large-diameter portion 4, and the hole of the arm 7 matches the small-diameter portion 5. Let it. Then caulking mold 1
0 advances while rotating, and the small-diameter portion 5 shown by a two-dot chain line
Is pressed, the portion is deformed to form the swaged flange 11. The axial length of the large diameter portion 4 is set slightly larger than the plate thickness of the arm 6 so that the arm 6 can rotate smoothly.

The component 1 is supplied from a parts feeder (not shown) to the guide member 12, where it is temporarily locked, held by the supply rod 13 that has advanced, and supplied to the recess 9 of the fixed mold. You. The guide member 12 is fixed to a stationary member 14, and a guide portion 15 is formed. An inlet 16 and an outlet 17 are formed in the guide 15, a supply pipe 18 is connected to the inlet 16, and an opening 19 through which the shaft 2 passes is provided. A supply hose 20 extending from a parts feeder is connected to the supply pipe 18. A cover plate 21 is fixed to the left and right in the vicinity of the entrance 16 and an opening 19 is continuous.

The guide surface 22 of the guide portion 15 is formed at a position one step lower than the surface 23 of the guide member 12, and the step between the guide surface 22 and the surface 23 of the guide member 12 is as shown in FIG.
The thickness is set to be equal to or slightly larger than the thickness of the flange 3 as shown in FIG. A guide wall 24 is formed by this step structure, and a positioning portion 25 is formed in a part thereof. The positioning portion 25 includes an arc portion 26 for receiving the outer peripheral surface of the flange 3 and a component holding means. The component holding means may have any function as long as it has a function of suctioning the flange 3 to the arc portion 26 or the guide surface 22.
Various methods such as a magnet type and a vacuum type can be adopted. In the case of the vacuum type, a small hole may be opened in the arc portion 26 or the guide surface 22 of the guide wall, and the air suction force therefrom may act on the flange 3.

In the case shown, the two magnets 27 are
6 is buried in the vicinity. A hole is drilled from the back side of the guide member 12, into which a permanent magnet 27 is inserted. As shown in FIG. 2, the magnets are configured as a set of two magnets.
The poles, north pole, south pole, and north pole are combined in this order. The guide member 12 is made of non-magnetic stainless steel in order to make the magnetic field lines of the magnet act more strongly on the component 1.

The supply rod 13 is made of an elongated member having a square cross section, and moves forward and backward by an air cylinder 28. The supply rod 13 is connected to the piston rod 29 of the air cylinder 28 by bolts 30 when the piston rod 29 advances, and passes through the outlet 17 to reach just above the recess 9 of the fixed mold 8. The supply rod 13 advances and retreats in a direction substantially orthogonal to the direction in which the supply rod 13 advances and retreats. As a mechanism therefor, an air cylinder 31 is fixed to the stationary member 14, and a piston rod 32 thereof is connected to the air cylinder 28. The moving direction of the piston rod 32 is substantially orthogonal to the moving direction of the piston rod 29. Therefore, by combining the forward and backward movements of the two air cylinders 28 and 31, the component 1 held by the supply rod 13 can be made to perform a square motion.

At the tip of the supply rod 13, a component holding means for the component 1 is installed. This means may be a chuck type made up of a pair of arms that can be opened and closed, or various methods such as a method in which a small air hole is opened at the tip of the supply rod 13 and vacuum is acted on the air hole to suck the parts. Can be adopted. In the case shown, it is a magnet type. Reference numeral 33 indicates the entire component holding means. Supply rod 13
The housing groove 34 is formed by a forked structure, and its inner wall is used as a holding wall 35. The innermost portion of the accommodation groove 34 is formed in an arc shape, and the shaft portion 2 is brought into close contact therewith. A regulating surface 36 of the flange 3 is formed on the lower surface of the supply rod 13, and this surface 36 is
2 or in a slight gap. The length of the regulating surface 36 is set to a distance that can suppress the floating of the flange 3 until the holding force of the component holding means 33 disappears when the flange 3 is fitted into the concave portion 9 and the supply rod 13 retreats.

A magnet 37 is buried near the back of the holding wall 35. Here, it is a pair of forms, each of which has two magnets stacked as shown in FIG. 2 and FIG. 5, and the polarity of each magnet is N pole, S pole, N pole, S pole in order from the top. They are arranged. By doing so, the lines of magnetic force pass through the component 1 as shown in FIG. 5, and no force is generated to attract a nearby magnetic body. Therefore, no suction force acts on the fixed mold 8, and no force for bending the supply rod 13 toward the fixed mold 8 is generated. Reference numeral 38 in FIG. 5 indicates a magnetic field line. The supply rod 13 is made of non-magnetic stainless steel in order to make the magnetic force act on the component 1 more strongly.

The large diameter portion 4 and the small diameter portion 5 of the shaft portion 2
In order to conform to FIG.
9 and a narrow portion 40 are provided. In order to cope with a change in the length of the large diameter portion 4 of the component 1, the height L2 of the large portion 39 is set larger than the length L1 of the large diameter portion 4 as shown in FIG. It is. In FIGS. 1 and 2, the guide member 12 and the fixed mold 8 are illustrated as being relatively close to each other, but they are actually spaced apart.

The operation of this embodiment will be described below. FIGS. 1 and 2 show a state in which the component 1 enters the guide portion 15 and the flange 3 receives the attractive force of the magnet 27 and conforms to the arc portion 26, and the component 1 is temporarily locked. I have.
In this state, the housing groove 34, the shaft portion 2, and the circular concave portion 9 are arranged in a straight line. Here, when the supply rod 13 advances by the air cylinder 28, the shaft portion 2 relatively enters into the housing groove 34, and coincides with the inner portion of the holding wall 35. When the supply rod 13 further advances, the component 1 held by the magnet 27 is forcibly pushed toward the outlet 17. At this stage, the component 1 receives the attraction force of the magnet 37 and is therefore held on the supply rod 13 side. The component 1 held by the supply rod 13 advances further away from the outlet 17, and stops when the flange 3 comes directly above the recess 9. Thereafter, the operation of the air cylinder 31 causes the entire supply rod 13 to move in a direction perpendicular to the direction in which the supply rod 13 moves, and the flange 3
Fit into.

With the flange 3 still fitted, the supply rod 13 is now retracted by the air cylinder 28. At the time of retreat, the regulating surface 36 moves while rubbing the surface of the flange 3 or with a slight gap therebetween, so that even if the attraction force of the magnet 37 acts on the component 1, the flange 3 may come off from the recess 9. Absent. Therefore, the length of the regulating surface 36 is set so as to function until the attractive force of the magnet 37 substantially disappears. Thereafter, before the supply rod 13 interferes with the guide member 12, the entire supply rod 13 is floated by the air cylinder 31.

Although not shown, an electromagnetic air switching valve and a control circuit for each air cylinder are provided in order to perform the above operations in order.
These are generally widely adopted and can be easily implemented.

FIGS. 8 and 9 show a modified example of the supply rod 13. FIG. Members having the same functions as those described above are denoted by the same reference numerals in the drawings. This modified example is a magnet 3
7 moves away from the holding wall 35. For this purpose, a sliding piece 42 is fitted in the guide hole 41, and a magnet 37 is embedded therein. An operating rod 43 is connected to the sliding piece 42. When the rod 43 is pulled, the magnet 37
Moves away from the holding wall 35. Although not shown, the operation rod 43 is driven by another air cylinder attached to the supply rod 13.

FIG. 10 shows an example in which the magnets 27 and 37 are replaced with electromagnets. The supply rod 13 is made of iron, which is a magnetic material, and penetrates through the electromagnetic coil 44. Also,
An electromagnet 45 is embedded in the guide member 12.

FIG. 11 shows a modification of the supply rod 13.
This is a single type from the two-part bifurcated shape as described above. Parts that perform the same functions as those described above are denoted by the same reference numerals in the drawings.

Although not described in the claims, the following matters can be recited in the claims. That is, the shaft portion of the component is held by the bifurcated supply rod, and the supply rod advances to supply the flange to the concave portion of the fixed mold for caulking. In this way, the parts can be supplied to the mold while holding the shaft portion with good stability at the forked portion.
In addition, since the flange is slid on the guide surface and the component positioning portion is provided in the middle thereof, the component can move smoothly.

FIGS. 12 to 14 show an embodiment in which a function of sucking a component stuck in the recess is provided. FIG.
In the case of No. 2, two elongated rod-shaped magnets 46 are inserted. The bottom surface of the concave portion 9 is circular, and two magnets 46 are arranged on the diameter line. The magnets 46, 46 are arranged in the axial direction of the fixed mold 8, and the upper side of one magnet 46 is an N pole, the lower side is an S pole, and the other magnet 46 is of the opposite polarity. The magnets 46, 46 make an elongated hole in the fixed mold 8, insert it there, and then cover it with a synthetic resin lid 47,
47, and bolts 48, 4
8, the magnets 46 are fixed. With such a magnet arrangement, the lines of magnetic force flowing from one magnet to the other magnet pass through the portion of the flange 3 of the component 1, so that the portion above the flange of the component 1 is not magnetized. It is similar to the phenomenon in FIG. The fixed mold 8 is made of non-magnetic stainless steel in order to allow the magnetic flux to pass through the component more.

In the case of FIG. 13, a rod-shaped magnet 49 is buried in the diameter direction of the fixed mold 8, and the right side is the S pole and the left side is the N pole. Therefore, the magnetic lines of force mainly pass through the flange 3, and the shaft portion 2 is not magnetized.

FIG. 14 shows a case where the flange 3 is sucked by vacuum. That is, the suction hole 5 is formed in the bottom of the recess 9.
Two or three 0 and 50 are left, and this is the passage 5
1 and an air hose 52 connected to a vacuum pump (not shown). The component 1 fitted in the concave portion 9 is firmly held by the flange 3 being suctioned by the vacuum from the suction holes 50, 50.

The supply rod that has advanced does not interfere with the outer peripheral surface of the flange or the corners of the flange, and securely retains the shaft to transfer the component from the outlet to the target location. This means that the shaft of the component is retained. Therefore, the shaft portion is held by the supply rod, and the flange can be immediately fitted into the counterpart concave portion, thereby increasing the efficiency of component supply.

A concave portion for receiving the flange is formed at the supply position of the component, and the supply rod holding the component moves in a substantially right angle direction after moving out, whereby the flange is fitted into the concave portion, Since the supply rod is retracted in this fitted state, the part having the largest outer shape of the component is fitted into the concave portion to make it stable, and then the supply rod is retracted, so the supplied component comes off the concave portion.

In other words, the regulation function on the regulation surface continues until the holding force of the component holding means disappears. Since the phenomenon of pulling back the component is prevented in this way, there is no problem even if the function of holding the component is strengthened. In other words, the stability of holding the component can be significantly improved.

The positioning portion comprises an arc portion for receiving the outer peripheral surface of the flange and a component holding means installed near the arc portion. Therefore, since the outer peripheral surface of the flange coincides with the circular arc portion, the position of the flange in the guide portion is always fixed at a certain position, and the standby position of the supply rod is uniformed,
The parts of the supply rod are held securely.

The component holding means in the supply rod is constituted by a magnet. Therefore, by using the magnet, the component holding means can be formed in a very simple and small space. In addition, by selecting the polarity of the magnet so that the magnetic field lines pass through the inside of the component, no force is generated for the component held by the supply rod to attract a nearby magnetic body. This means that when the component held by the supply rod approaches the member at the supply point, no suction force acts on this member, so that the supply rod does not tilt or bend, and the component is accurately supplied into the recess. It is done.

The feed rod is turned at right angles, whereby the flange is fitted into the recess, and the supply rod is retracted while staying in the fitted state. It is characterized by retreating while regulating the flange.

The component that has entered through the entrance portion has its flange moved along the guide surface and is temporarily locked at the positioning portion. In this state, the supply rod comes out and holds the part without interfering with the flange, and further the supply rod moves out and stops the part right near the concave part, and then the supply rod turns at right angles and moves Then, the flange of the component is fitted into the recess. When the supply rod is retracted in the fitted state, the flange is regulated by a regulating surface so as not to come off from the concave portion. In this way, each of the actuating elements allows smooth movement of the parts and secure insertion into the recess, so that a highly reliable device can be obtained.

A part in which a circular flange is integrated with a shaft part having a circular cross section is to be supplied. The supply rod has a holding wall of the shaft part and a regulating surface of the flange. The length of the regulating surface is set so that the regulating surface can regulate the flange so as not to come off from the concave portion when the supply rod is retracted in a state of being fitted in the concave portion.

This means that when the component held by the supply rod approaches the member at the supply point, no suction force acts on this member, so that the supply rod does not tilt or bend, and the component is accurately supplied to the target location. It is done.

Since the component is configured to be sucked into the concave portion, even when the counterpart component may come into contact with the shaft portion when fitting the hole of the counterpart component to the shaft portion,
Since the parts do not easily shift or come off, it is possible to solve the above-described problem such as the parts falling. Furthermore, since the passage of the magnetic field lines of the magnet is biased to a part of the part, no attraction force is generated in the other part of the part.
No abnormal suction force acts on the counterpart component even when the counterpart component is approached. Therefore, the counterpart part can be smoothly combined with the part, and a trouble such as the above-mentioned part falling can be avoided. Similar advantages can be obtained when using vacuum.
