Description

The present invention relates to a component supply control device, and a transfer passage communicating with an inlet passage and an outlet passage of a component made of a magnetic material has a case body. It is used for the type provided inside.

(B) Conventional technology When a component enters the transfer passage in the case body from the inlet passage of the component, the pusher member subsequently operates to transfer the component to the outlet passage, and then compressed air, etc. It is known to deliver from an exit passage.

(C) Problems to be Solved by the Invention In the conventional example as described above, when a component that has entered the transfer passage from the inlet passage collides with the inner wall of the transfer passage, the component is repelled. For example, it stops in a state in which a crotch is formed at the boundary between the inlet passage and the transfer passage. When the pusher member advances to such a place, a phenomenon occurs in which the component is caught in the boundary portion or is pushed back into the inlet passage, and normal transfer is not achieved.

(D) Means for Solving the Problem and Its Action The present invention is provided to solve the problems as described above, and the first term is connected to the inlet passage and the outlet passage of the component. A transfer passage is provided in the case body, and a magnet is installed at a temporary stop point where the inlet passage enters the transfer passage, and a magnet for stopping the component at a fixed position is installed, and the component positioned by the magnet is transferred to the outlet passage. The magnet is arranged at a position where the attraction force acts on the magnet in a direction to bring the component into contact with the inner wall of the transfer passage and the front end wall of the pressing piece. The parts that come into the transfer passage always stop at the proper position due to the attractive force of the magnet.At this time, the parts are brought into contact with both the inner wall of the transfer passage and the front end wall of the pressing piece depending on the installation position of the magnet. Of the magnet The arrangement is selected to apply such suction force.

In the second aspect, in the invention of the first aspect, the space of the transfer passage is substantially closed by the pressing piece so that the carrier air for the parts does not escape.

(E) Example Hereinafter, an example of the drawings will be described. FIG. 1 is a plan view of the entire apparatus, in which an air cylinder 2 is coupled to a case body 1 and a supply rail 3 for components is connected to the case body 1. An outlet pipe 4 is attached to the upper surface of the case body 1. The component 5 in this embodiment is a projection bolt, and the flange 6 is integrally formed with the bolt 6, and the flange 7 is provided with a projection 8 for welding.
The supply rail 3 is composed of a slide portion 9 having a shallow U-shaped cross section that is open upward and a lid plate 10 on the upper side thereof, and the lid plate 10 is provided with a space 11 through which the bolt 6 passes. Therefore, the component 5 slides in the posture shown in FIG.

The cross section (4)-(4) of FIG. 1 will be described with reference to FIG. 4. The case body 1 has a base plate 12 and a lid member 13 abutted against each other, and a fixing bolt 14 (see FIG. 5). And both are integrated. A shallow groove 15 having a size slightly larger than the flange 7 is formed on the base plate 12, while a narrow and deep groove 16 having a size slightly larger than the bolt 6 is formed on the lid member 13.
As a result, a transfer passage 17 having a shape similar to that of the component 5 as shown in FIGS. 4 and 5 and having a size slightly larger than that of the component 5 is formed. An inlet passage 18 communicates with the transfer passage 17, and in order to make the cross-sectional shape of the passage 18 similar to that of the transfer passage 17, a shallow groove 19 is formed in the base plate 12 toward the lid member 13.
A deep groove 20 is provided on the side of the feed rail 3, and the supply rail 3 and the inlet passage 18 are opposed to each other so that components can smoothly move. As is clear from FIGS. 8 and 9, the transfer passage 17 extends in the longitudinal direction of the case body 1, and the outlet passage 21 communicates with the transfer passage 17.

In the transfer passage 17, a pressing piece 22 having a cross-sectional shape (inverted T-shape) that exactly matches this passage shape is slidably inserted, and a piston rod 23 of the air cylinder 2 is connected. There is. The outlet pipe 4 is welded to the outlet passage 21 in a continuous state (see FIG. 7), and the delivery hose 24 is connected thereto. A nozzle pipe 25 is opened in the base plate 12 at a position coaxial with the outlet passage 21 and the outlet pipe 4, and an air hose 26 is connected to the nozzle pipe 25.

The pressing piece 22 is stopped at a position where its end face is in the same row as the shallow groove 19 as shown in FIG. 8 or slightly retracted to the right of the groove (not shown), and waits for the entry of the component 5. A magnet 28 for stopping the component 5 is installed at a temporary stop location 27 where the entrance passage 18 enters the transfer passage 17. In order to make the attraction force of the magnet 28 act so as to press the flange 7 against the bottom surface of the groove 15, the magnet 28 is attached so as to be fitted from the lower side of the base plate 12 and is covered with the cover plate 29. Further, in order for the flange 7 to contact both the inner side wall 30 of the groove 15 and the front end wall 31 of the pressing piece 22 so as to always obtain a uniform temporary stop point, the magnet 28 is shown in FIG. 3 and FIG. As can be seen, the flange 7 is installed at a position close to the inner wall 30 and the front end wall 31 from the center point 0. The selection of such a magnet installation location is performed by ensuring that the components are in contact with the inner wall 30 of the transfer passage 17 and the front end wall 31 of the pressing piece 22, that is, the attraction force of the magnet 28 realizes such contact. It means that the installation position of the magnet 28 is selected.

The case body 1 and the supply rail 3 described above are tightly fixed to a stationary member (not shown).
In order to make the magnetic force of the magnet 28 act more strongly on the component 5, the base plate 12, the lid member 13, the cover plate 29, the pressing piece 22 and the like are preferably made of a non-magnetic stainless steel material.
Further, it goes without saying that the magnet 28 may be an electromagnet instead of the permanent magnet as shown.

Next, the operation will be explained. The position where the pressing piece 22 is most retracted is the position shown by the chain double-dashed line in FIG. 8, and when the component 5 reaches the transfer passage 17 from the supply rail 3 via the inlet passage 18, The suction force of the magnet 28 acts on the flange 7
3 is attracted to the bottom surface of the groove 15, a suction force acts to the right in FIG.
Stops when it is firmly pressed against both sides. After that, when the pressing piece 22 moves to the left by the output of the air cylinder 2, the flange 7 is transferred while sliding on the bottom surface of the groove 15, and when the component 5 comes to a position concentric with the outlet passage 21, the transfer is stopped. Then, the compressed air from the nozzle pipe 25 is vigorously sent out toward the delivery hose 24 through the outlet passage 21.
At this time, since the pressing piece 22 closes the transfer passage 17 as shown by the two-dot chain line in FIG.
It effectively acts on the component 5 without escaping to.

(F) Effect According to the present invention, since the magnet is installed at the temporary stop position where the entrance path enters the transfer path, the parts that enter the case body always stop at a fixed position. As a result, as the standby position for transfer, the troubles described in the prior art can be reliably prevented. Further, since the pressing piece is installed so as to be able to move forward and backward, the component is accurately transferred to the outlet passage. And, the most important effect is that the parts where the parts are temporarily stopped are always made uniform. That is, the magnet is arranged at a position where the attraction force acts on the inner wall of the transfer passage and the front end wall of the pressing piece so that the component is in contact with the inner wall of the transfer passage and the front end wall of the pressing piece. The two contact points are contacted, and the temporary stop points are made uniform. further,
Since the pressing piece has a cross-sectional shape that substantially closes the transfer passage, air carried out to the component does not escape to the other, and a strong propulsive force can be applied to the component.
