And the screw S is fastened in the fastening position of a workpiece | work by the fastening apparatus (illustration omitted), and a screw fastening thing is manufactured.

  Here, the screw S is an example of a component. As an example, the screw S of the present embodiment is a male screw with a flange. More specifically, the screw S includes, as an example, a head S1, a shaft S2 extending from the head S1, and a flange S3 provided at an edge of the head S1 and the shaft S2 (see FIG. 2 and FIG. 2). (See FIG. 9). As an example, a cross groove is formed in the head S1 of the screw S (see FIG. 1). Although illustration is omitted, the screw fastener to which the screw S is fastened is manufactured by fastening a plurality of members (for example, two plates) with the screw S as an example.

  In the present specification, “supply” refers to delivery of the screw S from the take-out unit 38 of the supply device 10 to the transport device 12.

  Hereinafter, the configuration of the supply device 10 will be described with reference to the drawings, with each component being divided.

[Container and drive system]
The container 20 has a function of accommodating the screw S supplied to the transport device 12. As shown in FIGS. 1 and 2, the container 20 is, for example, a bottomed cylinder that opens at one end. The container 20 includes a cylinder 21 centered on the axis O and a disc 22 disposed on the other end side of the cylinder 21. The circular plate 22 is formed with a through hole 22A having a diameter D1 centered on the axis O (see FIG. 3). Here, the disk 22 is an example of a bottom. In FIG. 1, the screw S in the container 20 is not shown for easy understanding of the configuration of the container 20.

  The drive system 24 has a function of rotating the container 20 around the axis (about the axis O). Here, the drive system 24 is an example of a rotating machine.

  The gear 25 </ b> A has a through hole having a diameter D <b> 2 (see FIG. 3), and is fixed to the outer surface of the disc 22 around the axis O. The bearing 25B is a ball bearing having an outer diameter D2 and an inner diameter D3 (<diameter D1), and is fitted into the through hole of the gear 25A on the outer peripheral side and the outer periphery of the shaft 30 on the inner peripheral side (see FIG. 3). ). When the driving force is transmitted to the bearing gear 25 via the gear 26 by the electric motor 27, the container 20 is rotated around the axis (centering on the axis O). 1 to 3 indicate the rotation direction of the container 20.

  As shown in FIG. 2, the container 20 is disposed in an inclined state with respect to the horizontal direction (a direction orthogonal to the height direction) so that the disc 22 is located below. Therefore, the container 20 accommodates the screw S in a state where the screw S is brought close to the side where the disk 22 is disposed (see FIG. 2).

[Rake-up member]
The scooping member 28 has a function of scooping up the screw S in the container 20 and transporting it above the axis O (shaft 30) by rotating around the axis O together with the container 20. The scooping member 28 is disposed in the container 20 as shown in FIGS. The scooping member 28 is rectangular when viewed from a direction orthogonal to the axis O, and is in contact with the cylinder 21 and the disc 22 (see FIG. 2). Further, the scooping member 28 has a shape bent in an L shape toward the downstream side in the rotational direction when viewed from the direction along the shaft 30 (axial direction) (see FIG. 3).

  As shown in FIG. 3, the scooping member 28 includes an arcuate mounting portion 28A that contacts the cylinder 21 and a protruding portion 28B that is bent radially inward from the mounting portion 28A. The attachment portion 28A is bonded and fixed to the cylinder 21. The protrusion 28B is provided at a position upstream of the attachment portion 28A in the rotation direction of the container 20 (that is, the rotation direction of the scooping member 28). In the present embodiment, the angle of the protruding portion 28B with respect to the tangent line of the mounting portion 28A (the angle at which the protruding portion 28B is bent from the mounting portion 28A) is an acute angle. The scooping member 28 carries the screw S on the protruding portion 28 </ b> B along with the rotation of the container 20, and carries the screw S upwardly from the axis O (the shaft 30). The screw S carried to the upper side of the axis O (shaft 30) by the scooping member 28 falls to the shaft 30 side by gravity. The positional relationship between the scooping member 28 and the plate member 66 will be described later.

[shaft]
The shaft 30 has a function of rotatably supporting the container 20 around the axis (centering on the axis O) in a state where the container 20 is inclined so that the circular plate 22 faces downward. In other words, the shaft 30 has a function of supporting the container 20 so as to be rotatable about the axis (centering on the axis O) in an inclined posture with the disc 22 positioned below. Here, the shaft 30 is an example of a shaft body. As shown in FIGS. 1 and 2, the shaft 30 is disposed in an inclined state with respect to the height direction (or horizontal direction), and is fixed to a holding portion 52 of a support 50 described later. The shaft 30 rotatably supports the container 20 via the bearing gear 25. Further, a part (one end side) of the shaft 30 is disposed in the container 20 through the through hole 22A. That is, the shaft 30 passes through the disk 22.

  The shaft 30 is a rod-shaped member having a diameter D3 (see FIG. 3). As shown in FIG. 2, the shaft 30 has an upper portion extending from the inner side (inner side) to the outer side (outer side) of the container 20 with respect to the outer peripheral surface of the shaft 30, and the thickness of the head S <b> 1 of the screw S and the flange S <b> 3. Recessed larger than. A long flat surface 32 along the axial direction is formed in the recessed portion of the shaft 30 (see FIG. 3). Further, the portion where the flat surface 32 of the shaft 30 is formed and extends from the inner end of the container 20 to the outer end beyond the disk 22 extends in the longitudinal direction (axial direction). A long groove 34 that opens upward is formed (see FIG. 4A). As shown in FIG. 3, the cross-sectional shape of the groove 34 viewed from the axial direction of the shaft 30 is a rectangular shape. The groove 34 includes a bottom portion 34A on the lower side in the depth direction and an opening portion 34B that opens upward. In addition, an inclined surface 35 whose corners are chamfered is formed at the edge between the width direction both sides of the groove 34 and the flat surface 32. By providing the inclined surface 35 at the edge between the width direction both sides of the groove 34 and the flat surface 32, the screw S is less likely to be caught in the groove 34 than when there is a corner at the edge between the groove and the flat surface.

  Here, the width of the groove 34 viewed from the axial direction of the shaft 30 is narrower than the diameters of the head S1 and the flange S3 of the screw S and wider than the diameter of the shaft S2, as shown in FIG. Further, the depth of the groove 34 is deeper than the length of the axis S2, as shown in FIGS. With the above relationship, the shaft 30 is in a state where the shaft S2 is inserted into the groove 34 and the head S1 and the flange S3 are supported by the plane 32 (hereinafter, sometimes referred to as a “predetermined holding state”). The screw S can be held. Furthermore, since the plane 32 is inclined along the axial direction of the shaft 30 as described above, the shaft 30 allows the held screw S to pass from above to below due to its own weight. As described above, the shaft 30 is opened upward from the inside of the container 20 to the outside, and the groove 34 through which the screw S is passed is formed. The through hole 22A of the disk 22 of the container 20 is an outlet through which the screw S passes from the inside of the container 20 toward the outside. That is, the through hole 22A is an example of an outlet. Here, the “exit” refers to an opening that is formed in a part of the container 20 and the screw S inside the container 20 goes out of the container 20.

  As an example, the shaft 30 is provided with a long flat surface 33 that protrudes above the flat surface 32 and extends along the axial direction at a position adjacent to the flat surface 32 (see FIG. 4A). A concave portion 33 </ b> A for accommodating a later-described pressing spring 64 is formed at the end portion of the flat surface 33 on the flat surface 32 side.

  A plate-like body 80 disposed at the upper end of the shaft 30 is provided inside the container 20. The plate-like body 80 is joined to the upper end portion of the shaft 30 by adhesion or the like. A gap is provided between the outer peripheral surface of the plate-like body 80 and the inner peripheral surface of the cylinder 21, and the plate-like body 80 does not rotate when the container 20 rotates. The plate-like body 80 is provided with a circular opening 82 (see FIG. 1), and a plurality of screws S are introduced from the opening 82 to the lower side in the container 20.

It can be moved to.

  As shown in FIG. 9, when the air cylinder 40 is in the lower position P1, the groove 34 of the shaft 30 and the groove 42 of the air cylinder 40 are continuously connected. At this time, the width of the groove 34 in the direction orthogonal to the axial direction of the shaft 30 is equal to the width of the groove 42 in the direction orthogonal to the axial direction of the shaft 30. In addition, the take-out portion 38 is provided with a magnet 46 that attracts a screw S, which is a magnetic body, on the back side and obliquely below the groove 42 of the air cylinder 40 in the holding portion 52 described later. Thereby, when the air cylinder 40 is in the lower position P1, the screw S that has reached the groove 34 of the lower end portion 30A of the shaft 30 is supplied from the groove 34 to the groove 42 of the air cylinder 40. Thus, the screw S is in a state where the shaft S2 is inserted into the groove 42 of the air cylinder 40 and the head S1 is supported by the flat surface 44 of the air cylinder 40. At this time, the screw S is attracted to the magnet 46, so that the shaft S2 of the screw S is easily inserted into the groove 42 of the air cylinder 40.

  Further, as shown in FIG. 8, when the air cylinder 40 moves to the upper position P <b> 2 with respect to the shaft 30, one screw S is taken out. Then, the screw S is supplied to the transport device 12 by being gripped by the grip portion 12A of the transport device 12, and the screw S is transported to the fastening position determined by the transport device 12.
