PURPOSE:To carry out smooth feeding and machining by feeding a part having a hole from a temporarily stopping chamber having nearly a horizontal outlet on the end of a passage member, with its hole axis kept horizontally to a placing member provided near said outlet by means of a push-out device, and retracting said passage member at the time of machining. CONSTITUTION:A part 5 passes through a passage member 1 having a rectangular section with its hole axis kept horizontally, enters a temporarily stopping chamber 2 having a permanent magnet 4 on its end part and is adsorbedly stopped by it, pushed out of an outlet 3 by means of a small diameter part 9 of the piston rod 7 of an air cylinder 6, and placed on a placing member (lower electrode) 13 having a guide pin 14. After that, the passage member 1 is rotated centering around a rotating shaft 16 and retracted and, after an upper electrode 15 is lowered to carry out welding, the passage member 1 is returned by a spring 18 and positioned by a stopper 19. Accordingly, a moving distance can be reduced while the part 5 can be smoothly and securely fed to and machined on the placing member 13.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a supply device for parts with open holes, such as projection nuts that grow screw holes and welding protrusions. It is suitable for cases such as transferring onto a lower electrode, and cases where a distance piece with a through hole is to be supplied to a predetermined location.

(CJ) Conventional Technique 1g Two examples of the most orderly S moat in the above-mentioned component transfer are the case of supplying a projection nut. In the prior art in this kind of case, the tip of the wood of the copper alloy layer is a fixed pole, and a guide groove with a shallow but considerable length fI is formed up to the tip of the pole. The part, ie, the projection nut, is pushed out by the piston wood of the cylinder along the long i-groove.

UJM points that e1 Seimei aims to solveAccording to the above-mentioned conventional technology, the time required to move the parts is long, and if there is welding spatter or other impurities attached to the guide groove. , parts often get caught in it and come off the guide groove. This means that the part is not transferred to the part to be fixed, for example, to the quasi-pole of the part.

B) Rounding means for solving the aft problem and its construction No. 1 In order to solve the above problems, the present invention provides a completely submerged temporary chamber having an outlet opening in a substantially horizontal direction at the distal end of the passage member. Temporary locking means is provided in a part of the temporary locking chamber so that the axis of the hole of the component in the locking chamber is substantially horizontal, and a component extrusion device is attached to the passage member in the portion forming the temporary locking chamber. , a member on which the parts are placed is arranged near the outlet, and a means is provided for retracting the passage member when the part is processed, so that the parts in the board chamber are not placed very close to each other. The extrusion device i! is applied to the member on which the positioned part is placed. Therefore, the transfer can be carried out in a short time and accurately.

...) Example As is clear from the above-mentioned industrial fields of application, the present invention is applicable to a wide variety of types of parts and types of processing, but in this example, a projection nut is transferred onto the lower electrode. Indicates when to do so.

A temporary locking chamber 2 is provided at the tip of the stainless steel passage member 1 having a rectangular cross section, and an outlet 5 opening in a substantially horizontal direction is provided therein. A permanent magnet 4 serving as a stopping means is fixed.

The PROJE KUNYON nut 5 is placed in a trap and upright position so that the axis of its screw hole is approximately horizontal (Fig. 2, -, 1).
55) enters the temporary locking chamber 2, and is attracted to the permanent magnet 4, thereby determining the temporary locking position.

There are various specific examples of the parts extrusion device, such as an electromagnetically actuated extrusion plunger and a link actuated plunger, but here, the piston rod 7 of the air cylinder B is used as an example. The piston rod 7 is provided with a large diameter portion 8 and a small diameter portion 9, and the boundary between the two is an extrusion surface 10. The extrusion device is attached to the passage member 1 in the portion forming the temporary locking chamber 2, and the extrusion device is attached to the passage member 1 through a collar 11 as a member, and the piston is inserted through the through hole 12 made in the side plate of the passage member 1. The rod 7 enters the temporary locking chamber z, and the positions of related parts are set so that the screw hole of the temporarily locked nut 5 and the small diameter portion 9 are coaxially aligned. ing.

The member to which the part is It corresponds here to the lower electrode 13 and is arranged in close proximity to the outlet 3. The appropriate distance between the two is about 1.5 to 3 times the thickness of the nut 5, but it may be less than or more than the above value depending on the usage and the relationship with peripheral equipment. A guide pin 14 protrudes from the center of the lower electrode 13, and the upper electrode i1s facing the same electrode 1511C is reinstalled.

When the parts are processed, ie when the upper electrode 15 is lowered and welding is performed, means must be provided for retracting the passage member 1. This is because in order to effect the movement of the nut 5, the passage member 1 must be set at a higher position than the upper surface of the lower electrode 13, but in order to do so, the passage member 1 must be retracted. This is not the case. In FIG. 1, a passage member 1't is mounted on a stationary member 17 by a pivot 16 so as to be able to swing vertically, and is positioned by a coil spring 18 and a stopper 19. The above retracting means is a rough theory of the passage member 1 centered around the pivot shaft 16, but instead of this, it is also possible to retract in the direction of parallel movement using the cylinder rod 20 as shown by the 11th chain double-dashed line. .

In the explanations so far, the temporary locking means has been constructed of permanent magnets as shown in FIGS. 1 and 2, but FIG. 8 shows a pivot type opening/closing lid instead. That is, the pivot 21 is fixed to a part of the passage member 1, and the opening/closing lid 22 is supported by this, and although not shown, a torsion coil spring wound around the pivot 21 keeps the opening/closing lid 22 always in the closing direction. elasticity? Please accept it.

Note that reference numeral 23 in FIG. 1 is a vinyl hose with a rectangular cross section that is connected to the passage member 1 and extends from a parts feeder (not shown).

Furthermore, the nuts can be transported to the temporary locking chamber 2 by forcefully sending them one by one using air pressure, or by arranging them in a circle in a passage member and using the nuts' own weight from above to push them. .

Regarding force transmission when retracting the passage member 1, '9th
Examples are shown in FIGS. In FIG. 9, it is pushed down by the upper electrode 15 and directly pushed and retracted by the fC sheet metal part 241C. In Figure 10, it is evacuated by an auxiliary arm 25 extending from the upper 11 pole 15. Furthermore, FIG. 11 shows the piston rod 2 of the cylinder 26 provided separately.
It was evacuated at 7. Note that it is appropriate for the operator to hold the sheet metal part 24 by hand and wait at a certain position, or to use some other support.

Figures 2 and 3 show a state where the nut 5 is attracted by the permanent magnet 4 VC in the board Joko 2 and the position is determined, and when the piston rod 7 advances, its small diameter As the part 9 enters the screw hole, it passes through the outlet 6 while being moved to the nut 5' by the extrusion surface 10. In Figs. 1j is a schematic representation of the behavior until it is loaded, and ′i
Fig. sA shows a state in which the nut 5 is on standby, Fig. 5 shows a state in which the nut is moving while being locked to the tip of the piston rod 7, and Fig. 5 shows a state in which the nut 5 is moving while being locked to the tip of the piston rod 7; Fig. 7 shows a state in which the nut is tipped over, and the piston rod is returned to its original position after the nut has fallen down. These series D111: Dynamic V is set to a value that is almost the same as the falling speed of the gold nut, or slightly faster than the advancing speed of the piston rod 7, to prevent the nut from propagating rg'. is appropriate. In addition, since the distance between the exit 3 and the lower part 1j13 is short, it can be said that the nut is thrown into a strange state.

'$12 The example of the figure below is EE ra a 1! In this case, the passage member 1 is placed in a slightly inclined position as shown in the figure (the figure is exaggerated). Then, the piston rod 7 is also set at Vζ so as to advance slightly downward. However, the axis of the screw hole of the nut is slightly inclined to the temporary fixing base circle d, and the force S is approximately horizontal. By making this distinction, the nut 5 behaves as if it were to fall halfway into the recess.

In the example row shown in Fig. 1, the passage member 1 extends almost horizontally, and the VC temporary fixing chamber 2 at its tip is damaged. In this case, the passage member 1 is very short, and its tip is oriented in the upward direction, and the inside thereof becomes the temporary fixing chamber 2, and the curved part 29
A vinyl hose 23 is connected to. The extrusion equipment A for the parts is the same as in the previous case.

An actuating rod 30 that moves up and down is coupled to the air cylinder 6, thereby forming a means for retracting the passage member. Incidentally, a permanent magnet 4 is attached here as a temporary locking means at a position as shown in the figure.

FIG. 14 is a plan view showing still another embodiment,
The passage member 1 is designed to be able to rotate in the horizontal direction around a pivot @ 31, and when the supply of parts onto the F part i8 j'M 1q is completed, the passage member 1 is rotated and retracted counterclockwise by the retracting cylinder 32. It is something to do.

(f) Effects Since the present invention uses the tank formation function as described above, it is possible to transfer the perforated component km, which is kept on standby in a predetermined posture, onto a mating member. In particular, since the exit of the temporary fixing chamber and the member on which the component is mounted are placed in a very close relationship, and the hole in the component is oriented almost horizontally, the component cannot be moved by the extrusion device. Place the parts on the other party's parts easily and reliably in a short time! 2'I11, and there is no problem with spatter etc. as in the conventional example. Further, since the means for retracting the passage member VC is associated, the passage member does not become an obstacle during some processing such as welding.
