Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dual chute in cold forging.

The chute refers to a slightly inclined material path for guiding and directing the material toward the press.

This chute is used depending on the shape of the material, such as a pipe-shaped chute for relatively long materials, and a so-called flat chute with a U-shaped cross section for relatively flat materials.

On the other hand, materials handled by the same press machine also
Due to the influence of high-mix, low-volume production, they have come to be available in a wide variety of shapes. In addition to this, there has been an increasing demand for improved productivity, that is, a reduction in setup time.

The present invention has been made to meet this demand, and will be described below based on the drawings, which are one embodiment of the present invention.

In FIG. 1, a press machine 1 is provided with a transfer feed device 1a and its feed bar 2. As shown in FIG. As is well known, raw materials, pressed semi-finished products, products, etc. are conveyed by this feed bar.

Adjacent to the press 1 is a series of feeding devices for the materials to be handled by the press.
In this embodiment, this series of supply devices includes a material feeding device 3 for feeding materials together into a stock conveyor 4, and a material feeding device 3 for feeding materials together into a stock conveyor 4; A switching duct 5 for selecting and guiding the material, a first orientation 6, a second orientation 9, and a first It consists of a pipe chute 7 provided on the exit side of the orientation 6, a material alignment device 8 provided in the middle thereof, and a flat chute 10 provided on the exit side of the second orientation 9.

In this embodiment, the pipe chute 7 is provided at the side opening of the press machine 1, and the flat chute 10 is provided at the front left side of the press machine 1.

It is impossible to share the terminal ends of both chute 7 and 10 because the device for delivering the material coming out of the chute to the feed bar is adapted to the shape of each material, so mutual interference is avoided. It is located in a different place to avoid it.

When the material supplied to the material input device 3 is relatively elongated, that is, when the material requires a pipe-like chute, the switching duct 5 provides a passage to the first orientation 6. The passage to the second orientation 9 is closed. At the stage of moving up the belt conveyor for the first orientation, only those whose conveying posture is normal are taken out and passed through the pipe-shaped chute 7 and enter the material aligning device 8. The alignment device aligns the front and back of the material in the longitudinal direction so that it is to be fed to the press, and the material is guided through the pipe-like chute 7 to the press machine 1. The material exiting the pipe-like chute 7 is delivered to the feed bar 2 by a delivery device 11.

When the material fed to the material input device 3 is relatively flat, that is, the material requires the use of the flat chute 10, the switching duct 5 closes the passage to the first orientation 6 and closes the passage to the first orientation 6. Open the passage to orientation 9 of 2. When the materials that have arrived at the second orientation 9 are moved up by the orientation belt conveyor, only those that are in a normal conveyance posture are taken out and enter the flat chute 10. The material coming out of the flat chute is transferred to the delivery device 12
It is delivered to the feed bar 2 by.

In FIGS. 3 and 4, a delivery device 1 connected to a pipe-like chute 7 is shown as an example of a delivery device.
1 is shown. The delivery device 11 includes a pipe-shaped chute 7.
A chute member 13 is provided which is connected to and guides the material 14. The foremost material 14 is stopped by a rotating pawl 15 rotated by a cylinder device 15a. A cylinder device 16 is provided that holds and stops the next material 14 when the rotating claw 15 moves up and passes the first material 14. A rotary chute 17 is provided at the outlet of the chute member 13, which is rotatable around a fulcrum pin 17a, and when rotated by a spring 17b, it waits for the material 14 at the position indicated by the dashed line, and the material 14 enters the rotary chute 17 and is prevented from passing through. When it comes into contact with the plate 18 and stops, the rotating force due to the weight of the material 14 overcomes the biasing force of the spring 17b, and the rotating chute 17 rotates and stands almost upright. A pusher member 19 is provided below the rotary chute 17 and is moved forward and backward by a cylinder device 21. When the pusher member 19 retreats and stops, a push rod 20 fixed to the pusher member 19 pushes the notch of the rotary chute 17. Push it upright. The blank 14 falls from the pivot chute 17 into the pusher member 19. The position where the pusher member 19 advances and stops is the delivery position 2 where the material 14 is delivered to the feed bar 2.
Two holes are provided. The material 14 falls from the pusher member 19 into the hole at the transfer position 22 and passes through the pusher member 19. When the rotating claw 15 rotates down, the piston rod of the cylinder device 16 is retracted, and the material 14 advances until it is received by the rotating claw 15. By repeating these operations, the material 14 sent from the pipe-like chute 7 continues to be delivered to the feed bar 2.

The material 14 sent from the flat chute 10 is delivered to the feed bar 2 by a delivery device 12 having a similar structure.

Since the present invention has the above-described configuration, it is possible to cope with changes in the materials handled by the same press machine, and shortening of setup time can be expected. In other words, it is recognized that it is compatible with high-mix, low-volume production and is effective in improving productivity.
