As can be seen from FIGS. 1 to 7, particularly FIG. 5, the device of the present invention is a component that is inserted from the hopper 11, takes out the linear components 2 stored in the chamber 1, aligns them, and supplies them to the outside of the device. It is a supply device, and includes a rotation roller 3, a relay guide 4, and an alignment guide 5.
Here, the linear component 2 refers to a substantially linear component such as a pin shape, a rod shape, a column shape, a cylindrical shape, or a knock pin in the present embodiment. The component 2 is made of a material that can be adsorbed by a magnet 6 described later, for example, an iron-based material such as iron or steel.

The rotating roller 3 is a roller that attracts and takes out a plurality of parts 2 housed in the chamber 1 with six magnets 6 in this case.
In this case, the six magnets 6 are provided on the outer circumferential surface of the rotating roller 3 at positions shifted in the axial direction and the circumferential direction of the rotating roller 3 (see FIG. 6). As described above, the plurality of (six) magnets 6 are dispersedly arranged on the outer peripheral surface of the rotating roller 3 so that the adsorption and extraction by the magnets 6 of the components 2 housed in the chamber 1 are uniformly and efficiently performed. This is to disperse the fall of the component 2 on the alignment guide 5 in terms of time and position, as will be described later.
Each magnet 6 is embedded so as not to protrude from the outer peripheral surface of the rotating roller 3. Each magnet 6 is basically of any type of electromagnet or permanent magnet, but permanent magnets are used in consideration of the structure and simplification of handling.

The relay guide 4 is a guide that slides the component 2 that is attracted to the plurality of magnets 6 and is taken out from the chamber 1, and is interposed between the rotating roller 3 and the alignment guide 5.
In the present embodiment, the relay guide 4 is moved from the magnet 6 on the outer periphery of the rotating roller 3 by rotating the rotating roller 3 by moving the component 2 attracted to the magnet 6 on the outer periphery of the rotating roller 3 and being carried to the opposite side of the chamber 1. It is separated by scraping and formed so as to be slidable toward the alignment guide 5. Specifically, one end of the relay guide 4 faces the outer peripheral surface of the rotating roller 3 with a slight gap (at least a dimension smaller than the dimension in the short direction of the component 2), and the other end rotates the alignment guide 5. It consists of a downwardly inclined plate body that extends to an upper position on the roller 3 side or a position slightly closer to the center side of the alignment guide 5 than the upper end of the roller 3 side. Side walls 7 that prevent the component 2 from dropping from the relay guide 4 are disposed on both sides of the relay guide 4.

The alignment guide 5 is a guide that receives the parts 2 that have been slid and dropped on the relay guide 4 and aligns the parts 2 in the longitudinal direction, and is inclined downward in one direction and has a substantially U-shaped or V-shaped cross section (almost). (It is generally called a U-shape.).
A side plate 8 is attached upstream of the alignment guide 5. The side plate 8 is useful for, for example, guiding the component 2 that has slid and dropped the relay guide 4 to the bottom side of the alignment guide 5.
Further, on the downstream side of the alignment guide 5, when the component 2 flows up and down, the upper component 2 falls from the alignment guide 5 by its own weight and is removed, so that the notch for jumping out is used. 5a is formed.

In the present embodiment, the aligned parts 2 are supplied to a knock pin automatic press-fitting machine that performs the next process. Therefore, the downstream end of the alignment guide 5 formed with the notch portion 5a and having a narrow width has the above-described configuration. A guide pipe 9 for supplying a knock pin to the automatic knock pin press machine is connected.
The guide pipe 9 is a downwardly inclined pipe that passes through the parts 2 reaching the downstream end of the alignment guide 5 one by one, and has an inner diameter that is slightly larger than the dimension of the part 2 in the short direction (maximum diameter of the knock pin). . Accordingly, even at the entrance portion of the guide pipe 9, it is possible to eliminate the upper part 2 when the part 2 flows vertically.
Of course, the supply destination (next process) of the component 2 by the guide pipe 9 is not limited to the above knock pin automatic press-fitting machine.
Reference numeral 41 in FIG. 4 denotes a tray for the component 2 that has been spilled or dropped from the alignment guide 5 when being put into the hopper 11, and is not shown in FIGS. 1 to 3.

Next, the operation of the present embodiment will be described with reference to FIGS.
As shown in FIG. 5, a large number of parts 2 thrown in from the hopper 11 are accommodated in the chamber 1 without restriction in the direction thereof.
From this state, when the rotating roller 3 rotates counterclockwise (see arrow 51) in FIG. 5, the parts 2 adsorbed by the magnets 6 distributed on the outer periphery of the rotating roller 3 are separated from the chamber 1 side. Carried to the other side. When the component 2 reaches the position of the relay guide 4, the component 2 is separated from the magnet 6 on the outer periphery of the rotating roller 3 by being scraped by one end of the relay guide 4 (right end in FIG. 5). It slides and falls onto the alignment guide 5 from the other end (left end in FIG. 5).
The part 2 is separated from the magnet 6 on the outer periphery of the rotating roller 3 and dropped onto the alignment guide 5, as shown in FIG. 6, the magnet 6 is dispersed at positions shifted in the axial direction and the circumferential direction of the rotating roller 3. Therefore, they are dispersed (not concentrated) in both time and position.

When the part 2 slides on the relay guide 4 and falls on the alignment guide 5, the component 2 slides on the relay guide 4 while receiving an action in which the longitudinal direction thereof is directed to the extending direction of the alignment guide 5. (See arrow 71 in FIG. 7).
The component 2 that has fallen onto the alignment guide 5 flows down in the downstream direction by its own weight due to the downward inclination of the alignment guide 5 (see arrow 72 in FIG. 7). Here, since the alignment guide 5 is formed in a bowl shape having a substantially U-shaped cross section, the component 2 flows down while receiving an action such that the longitudinal direction thereof is directed to the extending direction of the alignment guide 5. That is, the parts 2 are oriented so that the longitudinal direction of each part 2 is aligned with the extending direction of the alignment guides 5, from falling from the relay guide 4 onto the alignment guide 5 to flowing downstream in the alignment guide 5. To be aligned.

  When the component 2 is vertically overlapped on the upstream side of the alignment guide 5, when the component 2 reaches the downstream side of the alignment guide 5, that is, the position where the notch 5 a for jumping is formed, The component 2 loses its support by the alignment guide 5 and falls out of the notch 5a by its own weight and is removed from the alignment guide 5 (see arrow 81 in FIG. 8). In addition, illustration of the side plate 8 is abbreviate | omitted in FIG.

The part 2 that has reached the downstream end of the alignment guide 5 in which the notch 5a is formed and narrowed, that is, the aligned part 2 passes through the guide pipe 9 (see arrow 82 in FIG. 8). It is supplied to the knock pin automatic press-fitting machine which is the next process.
Since the inner diameter of the guide pipe 9 is slightly larger than the dimension in the short direction of the part 2 (maximum diameter of the knock pin), the upper part when the part 2 flows up and down also at the inlet portion of the guide pipe 9 2 can be eliminated.

As described above, according to the present embodiment, the following effects can be exhibited.
That is, since a plurality of (six) magnets 6 that adsorb the components 2 housed in the chamber 1 are provided on the outer circumferential surface of the rotating roller 3 at positions shifted in the axial direction and the circumferential direction of the rotating roller 3. Adsorption and removal by the magnet 6 of the component 2 housed in the chamber 1 can be performed uniformly and efficiently. Moreover, the fall of the component 2 on the alignment guide 5 can be dispersed in time and position. Therefore, the parts 2 can be prevented from clogging at the entrance portions of the relay guide 4 and the alignment guide 5.
In addition, the alignment guide 5 has a substantially U-shaped cross section and is formed to extend downwardly and incline in one direction, and when the component 2 flows vertically on the downstream side, the upper component 2 is moved by its own weight. A notch 5a to be dropped was formed. Therefore, the reliably aligned components 2 can be supplied smoothly and easily to the outside of the apparatus, and clogging of the components 2 at the component supply destination (next process) can be suppressed.
Furthermore, in this embodiment, since the guide pipe 9 that passes the parts 2 one by one is connected to the downstream end of the alignment guide 5, this guide pipe 9 can be used as a guide pipe for supplying parts at the part supply destination (next process). Moreover, the parts 2 can be more reliably aligned.
