Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing material feeding device for conveying, for example, forging press material to a press delivery position.

[0002]

2. Description of the Related Art For example, in a forging press, various feeding devices are used to push out a working material contained in a stacker on a plane and sequentially convey it to a press delivery position. As this feeding device, a pusher plate is connected to a feed bar of a press transfer via a pin, and a pusher device having a recessed portion corresponding to the outer shape of the material to be processed is formed at the tip of the pusher plate. No. 4367, hereinafter referred to as the first pusher device), and a pusher member having a slight cylindrical portion for accommodating a processing material at its upper portion and capable of advancing and retracting, is provided at the delivery position. BACKGROUND ART A pusher device (see Japanese Utility Model Publication No. 62-5804, hereinafter referred to as a second pusher device) having a concave portion for accommodating the bottom of a material is known.

[0003]

However, since the first pusher device is not provided with a mechanism for preventing the processing material from collapsing, when the processing material having a small diameter and a long length is used, When the processing material is supplied from the stacker, it may fall down, or if the end surface of the processing material is not smooth, the processing material may fall down during transportation. Therefore, it has been pointed out that it becomes difficult to reliably convey the processing material to the press delivery position, and it is not possible to efficiently carry out the processing material feeding operation.

Further, in the first pusher device, the pusher plate is connected to the press transfer, and
This press transfer is connected to the press body. Therefore, for example, when the pusher plate is pushed out in a state where the processing material is locked in the stacker discharge port, an excessive load is applied to the first pusher device, and this load tends to act on the press body. At that time, the press coupling, which is a safety device of the press, is prevented from being disengaged and the load on the press body is prevented, and when the work material feeding operation is restarted, this press coupling assembly work, etc. There is a problem that it becomes necessary to restart the feeding operation quickly and easily.

Further, the first pusher device is provided with a pressing member for pressing the working material in the middle of conveyance from above so as to prevent the material from tipping over. There is a problem in that the height of the presser needs to be adjusted, which increases the man-hours of the entire work.

On the other hand, in the second pusher device, since the processing material is held by the pusher member and conveyed to the press delivery position, it is dropped and supplied to the concave portion provided at the press delivery position. The impact may cause the processing material to fall down. Moreover, the pusher member and the concave portion can correspond only to a single-size processing material, but when using various processing materials having different lengths, the pusher member and the concave portion can be processed according to each processing material. Since the member and the concave portion must be provided, there is a problem that the versatility is poor.

The present invention solves this kind of problem, and it is possible to reliably send out the material for processing, and at the same time, to feed the material for processing which can easily improve the efficiency of the whole processing operation. The purpose is to provide a device.

[0008]

In order to achieve the above-mentioned object, the present invention is a processing material feeding device for feeding a processing material received at a supply position to a predetermined delivery position, the actuator comprising: A swinging arm mechanism that is swingable under action, a pushing member that is connected to the swinging arm mechanism and that can move back and forth between the supply position and the sending position, and the swinging member that is openably and closably attached to the pushing member. A claw member for gripping the working material, and a link mechanism for releasing the claw member to release the gripping action of the working material when the claw member is arranged at the delivery position. Is characterized by.

[0009]

In the processing material feeding device according to the present invention described above, after the processing material is gripped by the pushing member and the claw member at the feeding position, the pushing material is pushed through the swing arm mechanism under the action of the actuator. The member is delivered to the delivery position. At this time, the processing material is securely gripped by the claw member, and even if the processing material has a small diameter and a long length, the processing material does not fall. Next, the pawl member is opened under the action of the link mechanism at the delivery position, so that the processing material is placed at this delivery position and is conveyed to the pressing position via, for example, the press transfer.

Therefore, the rod-shaped workpiece W held by the receiving member 44 fixed to the pushing member 16 and the claw member 18 is conveyed from the supply position A to the delivery position B on the flat conveying path 66 (FIG. 3). reference). After the pushing member 16 is stopped at the feeding position B, the cylinder 60 constituting the link mechanism 20 is driven and the rod 62 extends toward the pushing member 16 side, and the cam plate 64 fixed to the rod 62 moves. Then, the roller 56 of the link member 52 is pressed. As a result, the link member 52 swings toward the pushing member 16 side around the fulcrum 54, and the link member 52
The rod 48 engaged with the end of the rod is pulled in the direction opposite to the arrow X direction against the elastic force of the spring 50, and the claw member 18 engaged with the rod 48 is swung in the opening direction. .

When the claw member 18 is opened and the gripping action of the rod-shaped work W is released, the cylinder 12 is driven to move the rod 26 in the direction opposite to the arrow X direction, and the rack connected to this rod 26. The first arm member 34 is swung in the direction opposite to the arrow Y direction via the pinion 28 and the pinion 30. Therefore, the pushing member 16 returns to the original position (supply position A) under the pulling action of the second arm member 38, and the link member 5 moves while the pushing member 16 moves.
2 disengages from the cam plate 64, and the pawl member 18 is swung in the closing direction via the elastic force of the spring 50. After the pushing member 16 reaches the original position (supply position A), the driving of the cylinder 12 is stopped, while the cylinder 60 is driven and the cam plate 64 is retracted and stands by.

On the other hand, the rod-shaped work W arranged at the delivery position B is conveyed to a press position (not shown) via a press transfer (not shown) and a predetermined press work is performed.

In this case, in this embodiment, the pushing member 1
A claw member 18 for gripping the rod-shaped work W in cooperation with the receiving member 44 is swingably provided at the tip of 6.
Therefore, at the supply position A, when the bar-shaped work W is dropped and supplied from the stacker 68 with the pawl member 18 closed, it is possible to prevent the bar-shaped work W from falling due to the impact of the drop or the like.

Further, since the bar-shaped work W is grasped by the claw member 18 and the receiving member 44 and conveyed in the direction of the arrow X, the bar-shaped work W having a particularly small diameter and a long plane conveyance path 66.
Even if the rod-shaped work W whose surface in contact with is not smooth, it can be reliably conveyed to the delivery position B without falling over during the conveyance. Here, since the bar-shaped work W is gripped by the claw member 18 and the receiving member 44, even when the size (length) of the bar-shaped work W is different, the various bar-shaped works W can be reliably gripped. It has the advantage of being versatile and versatile.

Moreover, at the delivery position B, the claw member 18 is opened in a state where the end surface of the bar-shaped work W is in contact with the plane conveyance path 66, so that the bar-shaped work W is released when the gripping action of the claw member 18 is released. Does not fall and fall. As a result, it is possible to reliably and easily convey the rod-shaped work W supplied through the stacker 68 from the supply position A to the delivery position B.

Furthermore, the feeding device 10 according to the present embodiment.
Is a rack 28 connected to the rod 26 of the cylinder 12.
Further, it is provided with first and second arm members 34 and 38 which are swingable via a pinion 30 which meshes with the rack 28, and the pushing member 16 is engaged with the second arm member 38. Therefore, the movement amount of the rod 26 in the arrow X direction is increased via the swing arm mechanism 14 and transmitted to the pushing member 16, so that the rod-shaped workpiece W can be quickly transported from the supply position A to the delivery position B. Therefore, there is an effect that the cycle time of the whole press work can be easily shortened.

In addition, the feeding device 10 is not mechanically connected to the press transfer, and the pushing member 16 is moved back and forth in the arrow X direction via the cylinder 12 provided individually. Therefore, for example, two rod-shaped workpieces W having different lengths are simultaneously dropped and supplied from the stacker 68, and one rod-shaped workpiece W is fed to the stacker 68.
Even if a load is applied to the pushing member 16 by being locked at the discharge port of the press member, this load does not act on the press body. Therefore, the press coupling, which is a safety device of the press main body, does not come off, and when the feeding work of the rod-shaped workpiece W is restarted, the assembling work of the press coupling and the like becomes unnecessary, and the feeding work can be performed quickly and quickly. It can be restarted easily. As a result, there is an advantage that the efficiency of the entire press work can be easily performed.
