部品を移送するようにしている。 Conventionally, in automatic fasteners, etc., separation and pressure feeding devices for headed rod-shaped parts such as screws separate the plurality of rod-shaped parts that have been conveyed by being suspended from a chute at their heads one by one using a separator, and then force-feed the parts. The rod-shaped component is transferred by the pressure of the fluid that is fed from a pressure-feeding fluid source, through a fluid-feeding path, and into a component-feeding path.

不具合があつた。(Problem to be solved by the invention) Due to the structure described above, the fluid sent into the component feeding path hits the wall surface of the component feeding path on the opposite side from the spout of the fluid feeding path, causing the fluid to flow up and down. The fluid that flows separately in the direction and blows up toward the separator not only causes leakage and lowers the pumping efficiency, but also causes the rod-shaped part to move against the pumping direction.
There were problems with pushing up. In addition, in the case of short rod-shaped parts, there were problems such as the parts turning over during pressure feeding.

本考案は上記問題点を解決するためになされた

is suspended and transported toward the separator 3. The separator 3 includes a slider 8 to which a slider plate 7 is fixed and a screw 1 separated from the chute 2.
A head guide 11 is attached to hold the separator and then feed it into the component feeding path 10. Both of these operate in conjunction with a piston 12 that occupies the main part of the separator 3. A hole in the separator 3 through which the screw passes is connected to a hose 4 via a hose connector 5 to form a component pressure passage 10. A nozzle 13 is provided at the upper part of the hose connector 5 connected to the hole through which the screw passes, and is inclined downward in the direction in which the screw 1 is pumped. The fluid supplied from the pressure-feeding fluid adjustment device 9 flows through the fluid feed path 6 provided in the separator 3.
Then, it is ejected from the nozzle 13 of the ejection port into the component pressure feeding path 10. This nozzle 13 is shown in FIG.
As shown in FIG. 4, the structure is such that the screw 1 is inclined in the pressure feeding direction, that is, downward, and opens at a position other than the radial center of the component pressure feeding path 10, so that the fluid flow is directed to the inner wall of the hose connector 5. It is configured to create a swirling flow that descends along the

る。 When the piston 12 of the separator 3 is in the "in" state, the positional relationship between the screw 1 conveyed by the chute 2 and the separator 3 is as shown in FIG. Next, when the piston 12 moves to the "out" state, as the slider 8 moves, the slider plate 7 fixed thereto pushes out the screw 1 at the most extreme position of the chute 2 toward the separator 3.
As shown in FIGS. 1 and 2. and,
The screw 1 is held in a groove provided at the tip of the head guide 11 at the upper part of the separation pressure passage 10. Then, when the piston 12 returns to the "in" state, the screw 1 held by the head guide 11 freely falls into the component feeding path 10. Next, at the same time as the piston 12 moves, the fluid supplied from the pressure-feeding fluid amount adjusting device 9 passes through the fluid feed path 6 and enters the component pressure-feeding path from the nozzle 13 provided at the spout.
0 and pumps the screw 1. In this case, since the nozzle 13 is configured as described above,
The fluid is ejected in a spiral manner in the pumping direction, applying dynamic pressure to the screw 1 being pumped and causing it to rotate.
