Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a material separating device for separating the materials to be molded by a press one by one.

[Prior Art] When the material is carried into the press by the conventional automatic carrier,
A material separating device is provided on the upstream side of the automatic carrying device to separate the materials continuously carried in by a chute etc. one by one and deliver them to the automatic carrying device.

As the material separating device, for example, Japanese Patent Application No. 62-19
No. 8262 has already been filed.

[Problems to be solved by the invention]

However, in the separation device of the above application, there is a part where the material spontaneously falls during the separation of the material, and since it includes a very unstable process both physically and temporally, it may not be in time for the cycle time of automatic transfer, There was a problem such as not being able to position a good material.

[Means and Actions for Solving Problems]

This invention has been made for the purpose of improving the above-mentioned problems, and in a material separating device for separating the material to be molded by a press etc. one by one before being conveyed by an automatic conveying device, in the chute below the chute. Is provided with a pocket for accommodating one of the materials falling vertically, and the pocket is connected to a rotary shaft rotated by a rotary cylinder,
The material accommodated in the pocket in the vertical direction can be rolled over, and in the vicinity of the pocket, there is provided an extruding member for pushing out the rolled material toward the cradle side. Since the directionality is constant, there are no temporal or physical instability factors, and synchronization with the automatic transport device is easy.

〔Example〕

 An embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 is a main body of the apparatus, and a material carrying-in port 1a is provided at a lower end of a chute 3 through which a material 2 to be molded by a press or the like continuously falls, and the material carrying-in port 1a drops from the chute 3. A pocket 4a for accommodating one of the materials 2 is provided.

The pocket 4a is fixed to one end side of a hollow rotary shaft 4 horizontally supported by the main body 1 via a bearing 5, and is rotated in the vertical direction by being rotated by about 90 ° together with the rotary shaft 4. One piece of material 2 can be rolled over. A base end portion of a lever 6 is spline-engaged with the other end side of the rotary shaft 4, and a rotary cylinder 7 rotatably supported on an upper portion of the main body 1 is attached to a front end portion of the lever 6. The tip end side of the piston rod 7a is pivotally attached, and the rotary shaft 4 is rotated by the rotary cylinder 7.

Further, in the pocket 4a, an extruding member 9 for extruding the overturned material 2 from the pocket 4a is provided.

The push-out member 9 is attached to one end of an operating rod 10 housed in the rotary shaft 4 movably in the axial direction by a fastener 11, and the other end of the operating rod 10 is horizontally attached to the rear portion of the main body 1. Rod 1 of ejected cylinder 12
It is pivotally attached to the tip of 2a, and the pushing cylinder 12 pushes the material 2 forward from the inside of the pocket 4a by the pushing member 9.

On the other hand, a temperature detector 13 for detecting the temperature of the material 2 (preheated for hot forging of the material 2) housed in the pocket 4a is provided below the pocket 4a.

The temperature detector 13 detects temperature from the amount of infrared rays emitted from the material 2, and the detection surface 13a has pockets 4
It faces the material 2 through a through hole 4b opened at the bottom of a, and at the same time as detecting the temperature of the material 2, has a function of detecting whether or not the material 2 is completely accommodated in the pocket 4a. A gate 14 is provided on the material 2 unloading side of the pocket 4a.

The gate 14 has a pin 1 near the bottom of the chute 3 at the top.
It is pivotally attached by 9 and is in the position shown by the solid line in FIG. 1 due to its own weight. When the material 2 is pushed out, the position shown by the virtual line in FIG.
The material 2 can be carried out by being rotated. Further, a lever 14a is provided in an upper portion of the gate 14 so as to project in a substantially inverted L shape, and an arc-shaped long hole 14b is formed in the lever 14a. Are engaged through.

The lower end of the link 15 is pivotally attached by a pin 18 to a bypass member 17 provided below the rotary shaft 4.

When the temperature of the material 2 stored in the pocket 4a is below a preset temperature, the bypass member 17 bypasses the material to prevent defective products from occurring. The support 17a is pivotally attached to the main body 1 side, and has a support 17a on the front end side that closes the bypass port 21 that opens at the lower front of the pocket 4a from below.

The bypass cylinder 2 is attached to the tip of the bypass member 17.
The tip of the second piston rod 22a is pivotally attached to the pin 20
The bypass member 17 can be moved down to the position shown by the phantom line in FIG.

In the figure, reference numeral 23 denotes a cradle for receiving the material 2 extruded from the pocket 4a, and the material 2 received by the cradle 23 is clamped by an automatic conveying device (not shown) and carried into a press or the like. .

Next, the operation will be described. When the material 2 continuously dropped from the chute 3 is housed in one pocket 4a, the rotary cylinder 7 rotates the rotary shaft 4 by about 90 °, so that the pocket 4a inside the pocket 4a is rotated. Material 2 is rolled over and succeeding material 2
And separated.

After that, the pushing cylinder 12 is extended, the pushing member 9 is moved forward through the operating rod 10, and the material 2 in the pocket 4a is moved.
The gate 14 is pushed open to the pedestal 23 by opening the closed gate 14 by its own weight and then carried into a press or the like by an automatic carrier device (not shown).

The above operation is repeated to separate the materials 2 that continuously drop from the chute 3 one by one. However, the temperature of the preheated material 2 is lowered during transportation, and the pocket 4 is removed.
When the temperature detector 13 detects that the installed value when it is accommodated in a is lower than the set value, the bypass cylinder 22 rotates the bypass member 17 to the position B of the phantom line in FIG. 1 in order to bypass the material 2. To move.

As a result, the link 15 connected to the bypass member 17
Also, since the gate 15 is opened by the link 15 in the half-opened state (position indicated by phantom line B ′ in FIG. 1) by the link 15, the material 2 extruded from the pocket 4a by the extruding member is guided to the gate 14. It falls to the bypass port 21, further falls to the carry-out means 25 via the chute 24 provided below the bypass port 21, and is carried out by the carry-out means 25 to be heated again.

[Effect of device]

In this invention, when the material dropped vertically in the chute is accommodated in the pocket, the pocket is rotated by the rotating cylinder to roll over and pushed out to the pedestal by the pushing member. Since there is no process for the material to fall naturally, there are no factors that are unstable temporally or physically, which facilitates synchronization with the automatic transfer device and also improves positioning accuracy. Occurrence can also be prevented.
