Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts distribution control device for feeding parts one by one to a plurality of pipes to be supplied.

0002

[Prior Art] To explain the conventional example shown in FIG. 5, a distribution member 2 is inserted into a case body 1 so as to be freely advanced and retracted, and a component receiving groove 3 is formed in the distribution member 2, and the distribution member 2 is connected to the case body 1. A supply pipe 4 communicates with the housing groove 3, and a plurality of supply pipes 5 are welded to the case body 1 and communicate within the case body 1. The air cylinder 6 is used to stroke the distribution member 2, and its piston rod 7 is connected to the distribution member 2. Part 8 here is a projection nut, and projections 9 for welding protrude from its four corners. As shown by the solid line, the nut 8 is waiting in the housing groove 3, and the distribution member 2 strokes here to deliver the nut 8 to one of the supplied pipes 5.

0003

[Problems to be Solved by the Invention] With the above structure, since the next nut shown by the two-dot chain line enters into the housing groove 3, the welding protrusion in particular inevitably enters. Therefore, since the protrusions for welding in particular inevitably enter, the protrusions may get caught when the distribution member 2 moves and cannot be stroked, or the protrusions 9 may slide on the inner wall of the case body 1. If there is even the slightest unevenness on the inner wall, the protrusion 9 will get caught, making it impossible to perform a smooth stroke, and ultimately making it impossible to perform normal and reliable distribution control.

[Means for Solving the Problems and Their Effects] The present invention has been provided to solve the above-mentioned problems, and includes a single supply pipe and a plurality of supplied pipes. The supply pipe is configured such that one of the two is movable relative to the other, and the supplied pipe is provided with a closing member that can be opened and closed, and the air nozzle is opened downstream of the closing member. The parts transferred from the pipe to the supplied pipe are sent out with compressed air after the closing member is closed.

[0005]

[Embodiment] First, the embodiment shown in FIGS. 1 to 3 will be described. A supply hose 12 is connected to an outlet pipe 11 of a vibrating parts feeder 10, and a supply pipe 13 is connected to the other end of the hose 12. has been done. Air cylinders 14 and 15 are attached to the supply pipe 13 for delivering the parts one by one. A plurality of supplied pipes 1 for the supply pipe 13
In the illustrated case, there are three pieces 6, which are firmly fixed to a stationary member 18 via a connecting member 17. A widening portion 19 is provided at the upper end of the supplied pipe 16, an air cylinder 20 for advancing and retracting a closing member to be described later is fixed to the supplied pipe 16, and an air supply hose 21 is connected thereto. and,
In order to move the supply pipe 13 to each supplied pipe 16, an air cylinder 22 is fixed to the stationary member 18, and its piston rod 23 is connected to the supply pipe 13.

[0006] To explain in more detail with reference to FIG. 2,
The air cylinder 14 is connected to the supply pipe 13 via the bracket 24.
The piston rod 25 is connected to a control pin 26. The control pin 26 enters into the supply pipe 13, and a through hole 27 is bored on one side of the supply pipe 13. The part 28 shown here is a projection nut similar to that described above (however, the protrusion for welding is omitted from the illustration), and is continuously fed from the supply hose 12, and the second Insert control pin 2 into the screw hole of nut 28.
6 is passing through. Another air cylinder 15 is also fixed to the supply pipe 13 via a bracket 29, and its piston rod 30 is connected to a control plate 31. Control board 3
1 also enters into the supply pipe 13, and a slit hole 32 is opened on one side of the supply pipe 13, and the first nut 28
is posted.

The air cylinder 20 is also fixed to the supplied pipe 16 via a bracket 33, and its piston rod 34 is connected to a plate-shaped closing member 35. The closing member 35 can enter into the supplied tube 16 and close the conduit, and a slit hole 36 is formed on one side of the supplied tube 16. A cross section of this part is shown in FIG. On the other hand, an air nozzle 37 is opened on the downstream side of the closing member 35.
An air supply hose 21 is connected to it. A delivery hose 38 is connected to the supplied pipe 16, and this hose and the above-mentioned supply hose 12 are made of flexible materials such as polypropylene and vinyl chloride. It is made of metal.

To explain the operation of this embodiment, in FIG. 2, the first nut 28 is stopped on the control plate 31, and the second nut 28 is stopped by being penetrated by the control pin 26, and the blockage is stopped. Member 35 is also closed as shown. The supply pipe 13 and the supplied pipe 16 are in a continuous positional relationship as shown in FIG. When the control plate 31 is first opened by the air cylinder 15, only the first nut 28 falls and stops on the closing member 35. Next, when the closing member 35 opens and the nut 28 falls inside the supplied pipe 16, the closing member 35 immediately closes to its original position, and when compressed air is ejected from the air nozzle 37, the nut 28 is released with force. through the delivery hose 38 to the destination (not shown)
sent to. Air from the air nozzle 37 passes through the closing member 3
5 is closed, the nut is forced to be fed without flowing backward upwards. While the above operations are being performed, the control plate 31 is returned to the closed position, and then the control pin 26 is moved back, and the nut 28 that was stopped second
stops on the control plate 31, and the third one moves to the second position, and the control pin 26 advances there, resulting in the state shown in FIG. 2 again.

When the supply of nuts to the central supplied pipe 16 is completed by the above operation, the supply pipe 13 is aligned with the adjacent supplied pipe 16 by the operation of the air cylinder 22, and the above operation is performed. Nut supply is performed and the distribution function is performed.

[0010] In order to obtain the above-mentioned operation, working air is supplied and discharged to each air cylinder in a predetermined order, but such supply control can be easily carried out using normal sequence control. Can be done.

In the embodiment shown in FIG. 4, the supply pipe 13 is fixed to the stationary member 18 with a bracket 39, and the supplied pipe 16 side is moved. A control board 31 is installed on the outlet pipe 11 of the parts feeder 10. Therefore, the piston rod 41 of the air cylinder 40 is connected to the connecting member 17, and the connecting member 17 is supported by a guide member 42 to ensure smooth operation. Since the operation of this embodiment can be easily understood from the previous embodiment, the explanation here is omitted.

[Effects] According to the present invention, since a single supply pipe and a plurality of supplied pipes are configured to be able to move relative to each other, there is no phenomenon in which parts get caught when moving to select a distribution destination, and as compared to the conventional technology. The problem will definitely be resolved. Furthermore, since a closing member is installed on the supplied pipe, backflow of the conveying air is prevented and a strong feeding force can be obtained.
