Figure 'i41 shows a sectional view in the longitudinal direction. This supply head is used for welding nuts (hereinafter abbreviated as nuts).
A fluid pressure cylinder 4 is fixed via a cover cylinder 2 to the rear part of the main body block 1 connected to the chute 3 through which the fluid is sent.
A rod 6 connected to the tip of the piston rod 5 of the fluid pressure cylinder 4 is arranged so as to be able to protrude from the main body block 1 through the cover cylinder 2.

診る。Therefore, the nut 20 fed from the chute 3 comes into contact with the wall part a and stops at the front position of the passage 8. Furthermore, as shown in FIG. 2, the folding screen 7 always has a coil spring 10.
10 and balls 11 and 11 in the closing direction, and are opened by the pressing force of the nut or rod 6. In addition, a gap is formed in the mating part of the door 7.7, and when the rod is pushed out, the air in the passage 8 is released through the gap.Therefore, when the nut 20 is force-fed by air, etc., the door 7. , to prevent and diagnose problems such as the door being opened inadvertently or the nut's posture being abnormal due to air being blown back.
本体ブロック１の後部に、カバー筒２がボルト１２によ

つナツト２０の内径Ｌ２より小さく形成される。At the tip of the rod 6, there is a jagged head 1 at the tip of the rod portion 15a.
A nut support portion 15 having a diameter 5b is formed. As shown in FIG. 5, the rod portion 15a of the nut support portion 15 has a diameter L1 smaller than the inner diameter L2 of the nut 20, and a length L3 slightly longer than the thickness (height) L4 of the nut 20. It is formed. Further, the diameter L5 at the base of the jagged head 15b at the tip is slightly larger than the diameter L1 of the rod portion 15a and smaller than the inner diameter L2 of the nut 20.
また、ぎぼし状であるため、その元部は球形状を呈し、

The tip thereof is formed into a substantially circular female shape. Note that the diameter L6 of the rod 6 is smaller than the outer diameter of the nut 20 and its inner diameter L2.
formed larger.
従って、ナツト供給時にロッド６が押出し作動した場合
、通路８の前部に位置するナツト２０の孔にナツト支持
部１５が挿通され、ナツト２０はそのナツト支持部１５
の棒部１５ａに掛けられて押し出される。Therefore, when the rod 6 is pushed out during nut supply, the nut support part 15 is inserted into the hole of the nut 20 located in the front part of the passage 8, and the nut 20 is inserted into the nut support part 15.
It is hung on the rod portion 15a and pushed out.
カバー筒２の後端部には、流体圧シリンダ４が固定され

、その場合のナツト挿入効果に差は生じない。An air traction hole 4a is provided inside the tip side of this fluid pressure cylinder 4, and the piston is braked at the extrusion end when the piston rod 5 is pushed out, and the piston stops without impact due to the air traction action. It has a structure that reduces impact noise. Note that it is also possible to use a fluid cylinder that does not have an air cursor structure, and there is no difference in the nut insertion effect in that case.

示しないナツトフィーダの分離供給装置に接続される。The supply head configured as described above is placed at a predetermined position on the workpiece 21 (guide pin 22) for welding the nut 20.
It is arranged so that it is tilted downward so that its front part is directed to the protruding position. Then, when the rod 6 is pushed out, the toothed head 15b of the nut support portion 15 is positioned so that it stops exactly slightly above the tip of the guide pin 22. Since its tip is easy to see compared to a sphere, alignment with the tip of the guide pin 22 is easy. The chute 3 is connected to a separate supply device of a nut feeder (not shown) via a feed hose.

。Next, the fluid pressure cylinder 4 operates to push out the piston rod 5, thereby pushing the rod 6 forward (Fig. 6). At this time, the nut support portion 15 at the tip of the rod 6 enters the hole in the nut 20. While moving forward, the forward force pushes open the doors 7.
5, the rod 6 moves forward toward the tip of the guide pin 22 of the workpiece 21. At this time, the rod 6 moves diagonally forward, but the nut 20
Since it is in contact with the serrated head 15b of the nut support portion 15, it is held there without falling. Further, when the nut 20 pushes open the door 7.7 and is released from the pressure of the coil springs 10, 10, the nut 20
When the nut 20 is pushed forward on the rod 15a of the nut support 15, the difference L7 between the length L3 of the rod and the thickness (height) L4 of the nut acts (Fig. 5). The low drag force (frictional force) generated when sliding between the nut 20 and the force of contact with the serrated head 15b absorbs the reaction force and prevents the nut 20 from popping out.

置に着地する。Then, when approaching the extrusion end of the fluid pressure cylinder 4, the forward speed of the piston rod 5 is reduced by the air traction action, and the jagged head 15b at the tip of the rod reaches directly above the guide pin 22 of the workpiece 21. At this time, the piston rod 5 and the rod 6 stop gently and without impact. At this time, the nut 20 supported by the nut support part 15
Place its lower end on the workpiece or part of the guide pin,
Due to its inertia force and its own weight, the nut 20 is rotated using the contact point as a fulcrum.
rotates forward. As a result, the nut 20 lands at a fixed position on the workpiece so that the tip of the guide pin 22 is inserted into the hole.

ツト支持部１５を離れワーク上の定位置に載置される。The tip of the nut support 15 has a serpentine head 15b and its base is spherical, so the nut 2o can smoothly slide through its inner hole on the serpentine head 15b, and the nut 20 can be smoothly attached to the nut support 15. is removed and placed in a fixed position on the workpiece.

載置することができる。In this way, the nut 20 is hooked onto the bar 15a of the nut support 15 provided at the tip of the rod and fed, and the forward end of the rod 6 rotates the nut 20 forward by sliding its jagged head 15b. Because it is placed at a fixed position on the workpiece 21, there is no need to limit the forward speed of the rod 6 compared to the conventional skewering type supply head, and a wider range of speeds can be selected, and it is stable and reliable. The nut can then be placed in place.

ナツトがワーク上の定位置に供給される。After the nut 20 has been supplied, the rod 6 returns to its original position within the cover cylinder 2 by the retracting action of the hydraulic cylinder 4.
At this time, #7 of the main body block 1 is closed by the biasing force of the coil spring 10, and the next nut enters the front part of the passage 8. From then on, the same operation as above is repeated, and each time the nut is Supplied in place above.

Thus, it is possible to feed nuts even when the rod 6 is horizontal.

The diameter of the base of the rod is slightly larger than the diameter of the rod and slightly smaller than the hole diameter of the nut, and the length of the rod is slightly longer than the thickness of the nut. Since the nut support part is inserted into the nut and the rod part supports and supplies the nut, the nut can be sent to a fixed position on the workpiece without using the magnetic force of the electromagnetic coil. The material may be purchased from materials other than magnetic materials, and the structure of the supply head can be simplified and lightened, and a control circuit for controlling the electromagnetic coil is not required. Also,
Compared to the conventional skewering method, the nut does not fall due to its own weight and is supported by the nut support at the tip of the rod while being fed onto the workpiece, allowing the nut to be stably placed in a fixed position on the workpiece.
