Can be moved to a position.

  Four bolt supply portions 6 are attached to the front portion of the base 2 so as to face the four guide rails 14 of the bolt alignment portion 5. As shown in FIG. 7, the bolt supply unit 6 is coupled to a cylindrical pipe member 25 (accommodating member) that accommodates a predetermined number of bolts B, and an upper end portion of the pipe member 25. A receiving member 26 for receiving the bolt B from the guide rail 14 and a take-out mechanism 27 coupled to the lower end portion of the pipe member 25 and taking out the bolts B accommodated in the pipe member 25 one by one are provided. .

  The inner diameter of the pipe member 25 is slightly larger than the outer diameter of the head B1 of the bolt B, the bolts B can be accommodated in a line along the axial direction, and the inner peripheral surface of the pipe member 25 and the bolt B The shaft portion B2 is set so as not to enter between the head portion B1. The pipe member 25 is a transparent tube made of, for example, polyvinyl chloride resin, acrylic resin or the like, and the state of the bolt B accommodated therein can be visually observed from the outside.

  The receiving member 26 has a substantially cylindrical shape having a bore 28 that has the same diameter as the inner diameter of the pipe member 25 and communicates with the inside of the pipe member 25, and the upper portion of the bore 28 is enlarged in a tapered shape to form an enlarged diameter portion 28 </ b> A. Has been. A guide cover 29 having a half-divided cylindrical shape is extended upward at the upper end edge of the receiving member 16 so as to face the tip of the guide rail 14 of the bolt aligning portion 5. The extension length of the guide cover 29 is slightly longer than the entire length of the bolt B. In this embodiment, the guide cover 29 is attached to the outer peripheral portion of the receiving member 26 as a separate body from the receiving member 26, but may be formed integrally with the receiving member 26.

  A bolt guide 30 (component guide) having an arc-shaped cross section extending from the center of the upper end inside the guide cover 29 to the vicinity of the lower end of the enlarged diameter portion 28A in the bore 28 is attached to the receiving member 26. The bolt guide 30 has a radius of curvature of the arc-shaped inner surface that is slightly larger than the outer diameter of the bolt B, and is substantially the same as the distal end portion of the guide rail 30 with the bolt supply unit 6 attached to the base 2. They are arranged so as to face vertically (φ = 90 ° in FIG. 7).

  The take-out mechanism 27 has a take-out member 31 having a two-divided structure that is divided in half in the vertical direction. Has been. The upper portion of the bore 32 is enlarged in a tapered shape to form a tapered portion 32A, and the upper end portion of the tapered portion 32A is slightly larger in diameter than the head B1 of the bolt B and communicates with the inside of the pipe member 25. . Each half 31A constituting the take-out member 31 of the divided structure (two-divided structure in the illustrated example) is supported by the pin 33, and the closed position shown in FIG. It is possible to rotate between the taken-out position. In each half 31A of the take-out member 31, a gripping portion 34 is extended upward substantially in parallel. Each half 31A of the take-out member 31 is biased to the closed position shown in FIG. 7 by a spring 35, and is in the take-out position shown in FIGS. 9 (A) and 9 (B) against the spring force of the spring 35.

The take-out member 31 may have a radially divided structure of three or more in addition to the illustrated two-divided structure.

  Next, the attaching / detaching mechanism 36 of the bolt supply unit 6 to the base 2 will be described mainly with reference to FIG. As shown in FIG. 10, the bolt supply unit 6 is detachably attached to a holding plate 37 that extends in the horizontal direction from the front portion of the base 2. A U-shaped notch 38 for receiving the pipe member 25 of the bolt supply unit 6 is formed at the front end of the holding plate 37, and the receiving member 26 of the bolt supply unit 6 is formed around the notch 38 on the upper surface of the holding plate 38. An annular recess 40 is formed to receive a ring-shaped retainer 39 attached to the lower part. A magnet 41 is embedded in a contact surface of the annular recess 40 with the retainer 39, and the retainer 39 is a ferromagnetic body to which the magnet 41 can be attracted. Thus, the pipe member 25 is inserted into the notch 38, and the retainer 39 is fitted into the annular recess 40, whereby the magnet 41 attracts the retainer 39 and attaches the bolt supply portion 6 to the holding plate in a detachable manner. it can. The bolt supply unit 6 may be attached to the base 2 by other known detachable means.

Next, the operation of the present embodiment configured as described above will be described.
A plurality of non-aligned bolts B are introduced into the insertion portion 4. The plurality of bolts B that have been thrown in are distributed uniformly while abutting against the inclined plates 13 that are alternately arranged, and drop onto the bolt orientation aligning portion 3. The bolt B dropped on the bolt orientation aligning portion 3 is received in the vertical groove 10 along the outer peripheral surface of the guide plate 11 and the pipe material 9 while sliding downward by the inclination angle θ, and the shaft portion along the vertical groove 10. The orientation is aligned with either B2 or the head B1 facing downward (see FIGS. 5A and 5B).

  The bolt B whose direction is aligned by the bolt alignment portion 3 is received by the guide rail 14 of the bolt alignment portion 5, and as shown in FIGS. 5 (A) and 5 (B), the shaft portion B2 is between the rails 14A by its own weight. The head B1 slides along the guide rail 14 while being aligned with the head B1 placed on the guide rail 14. At this time, the upper end portion of the head B1 of the bolt B to be aligned is guided by the guide member 16, thereby preventing the flange portion of the bolt B1 from overlapping.

  As shown in FIG. 6A, the bolts B aligned on the guide rail 14 are held on the guide rail 14 by abutting against the downstream stopper pins 18 protruding between the rails 14A by the cutting mechanism 17. . After the bolts B held on the guide rail 14 reach a certain number (9 in the illustrated example), the support plates 20 and 21 are operated so that the downstream stopper pin 18 and the upstream stopper pin 19 are moved as shown in FIG. ). As a result, the upstream stopper pin 19 protrudes between the rails 14A (holding position), holds the bolt B on the upstream side thereof, and the downstream stopper pin 18 retreats from between the rails 14A (release position), and the downstream stopper pin A certain number of bolts B between 18 and the upstream stopper pin 19 are slid along the guide rail 14. In this way, a certain number of bolts B can be cut out. Thereafter, the support plates 20 and 21 are operated to return the downstream stopper pin 18 and the upstream stopper pin 19 to the positions shown in FIG. As a result, the upstream stopper pin 19 retracts from between the rails 14A (release position), and the bolt B held by the upstream stopper pin 19 slides down on the guide rail 14 and protrudes between the rails 14A. It is held by (holding position).

  As shown in FIG. 7, the fixed number of bolts B cut out by the cutting mechanism 17 falls from the front end portion of the guide rail 14 and is received by the bolt supply unit 6. The bolt B falling from the tip end portion of the guide rail 14 abuts on the bolt guide 30 having an arc-shaped cross section, and slides along the bolt guide 30 into the enlarged diameter portion 28 </ b> A of the receiving member 26. At this time, since the bolt guide 30 is disposed substantially perpendicularly to the guide rail 14 (φ = 90 °), when the bolt B falling from the guide rail 14 collides with the bolt guide 30, Since the head portion B1 and the shaft portion B2 collide almost simultaneously, the bolt B smoothly slides into the receiving member 26 along the bolt guide 30 without being violated. The guide cover 29 covers the side portion of the bolt guide 30 to prevent the bolt B from popping outside even if the bolt B is dropped from the bolt guide 30.

  The bolt B dropped into the enlarged diameter portion 28A of the receiving member 26 further falls into the pipe member 25, the head B1 comes into contact with the tapered portion 32A of the take-out member 31 of the bolt take-out mechanism 27, and the shaft portion B2 Is held in a state of projecting outside through the bore 32. Then, a certain number of bolts B are sequentially dropped and held in the pipe member 25. At this time, since the pipe member 25 is transparent, the number and direction of the bolts B held inside can be visually confirmed.

  In this manner, after a certain number of bolts B are accommodated in the pipe member 25, the bolt supply unit 6 is removed from the holding plate 38 of the base 2 as shown in FIG. Install. As a means for installing the bolt supply unit 6, a method similar to the attachment to the holding plate 38 or other known detachable means can be used. Then, by picking the shaft portion B2 of the bolt B protruding outward from the take-out mechanism 27 and pulling it downward, the head B1 of the bolt B presses the taper portion 32A as shown in FIG. As the member 31 expands to the take-out position against the spring force of the spring 35, the bolt B can be taken out. Thereafter, the take-out member 31 returns to the closed position shown in FIG. 7 by the spring force of the spring 35 and holds the remaining bolts B in the pipe member 25. In this way, in the process of using the bolt B, a certain number of bolts B can be taken out one by one and used.

  If the bolt B is accommodated in the reverse direction, the takeout member 31 picks up the gripping portion 34 and resists the spring force of the spring 35 as shown in FIG. 9B. Therefore, the reverse bolt B can be easily removed.

  In the present embodiment, the bolt supply unit 6 may be fixed to the base 2 without being detachable when it is not necessary to remove the bolt supply unit 6. In the present embodiment, as an example, the case where the present invention is applied to a bolt aligning device for aligning bolts B, which are flange bolts, is described. However, the present invention is not limited to this, and other types are also described. The present invention can be similarly applied to a component aligning and supplying apparatus for aligning a bolt or a rivet or other component having a head and a shaft.
