Description

[Detailed explanation of the idea] The present invention relates to a transfer device.

Conventionally, a device as shown in FIG. 8 has been proposed and used as a transfer device for, for example, test pieces of rolled steel plates, scraps, and the like.

This device controls the linear movement of the cylinder 2' in the vertical direction.
The arm 9', which is shrink-fitted or keyed to the shaft 4', is rotated through the arm 5' to rotate around a shaft 4' supported by a bearing 3' fixed to the shearing machine body 1'. axis 4'
After rolling the steel pieces, test pieces, scraps, etc. onto a conveyor installed at the bottom of the shearing machine body using the claw 11' attached to the arm 9', the arm 9 is rolled in the reverse motion. It is designed to be swung up to a position where it does not obstruct the passage of the steel plate, that is, the position shown by the imaginary line.

In this way, conventional devices require a space in front of the shearing machine for the stroke of the claws, and shearing machines that require a rolled steel plate tensioning device (pinch roll) or the like on the front of the shearing machine,
Since product accuracy and product yield are important, the distance between the shearing machine body and the tensioning device becomes narrow, making it impossible to utilize this type of device.

The present invention was developed in view of these circumstances, and it solves the conventional problems with a simple configuration. - Through a continuous rotational motion, the motion is converted into a linear motion and a rotational motion, and this is converted into a linear motion and a rotational motion of the nail. It is made to work on a certain arm and allows objects to be transferred in a limited narrow space.

Next, the configuration and operation of the present invention will be explained with reference to the drawings.

1 and 2, the movement of the cylinder 2, which is fixed vertically to the shears body 1, is
A shaft 4 suspended horizontally between multiple bearings 3 fixed to a vertical wall of
The transmission is transmitted to the cylinder arm 5 which is integrated by shrink fitting, and further by a plurality of arms 6 which are integrated by shrink fitting to the shaft 4, a shaft is mounted between the arms 6 and is provided parallel to the shaft 4. It acts to rotate 7.

The arm 6 and the shaft 7 are slidably movable by a bush 8, and the operation of the arm 6 consists solely in rotating the shaft 7 attached thereto about the shaft 4.

The upper end of an arm 9 is attached to the shaft 7 by shrink fitting, and a claw 11 for holding a steel piece or a test specimen 10 is rotatable by a pin 12 at the lower end, that is, the tip of the arm 9. attached.

Arms 13 are attached to both ends of the shaft 7 in a direction opposite to the direction of the arm 9, and are integrated with the shaft 7 by shrink-fitting and guide the movement of the shaft 7. A bearing cover 15 which has a stopper 14, is fixed to the bush 8, and is integrated with the arm 6 is disposed on both sides of the arm 6.

A cylinder 16 having a contraction habit is installed between the arm 13 and the shaft 4, and this cylinder 16
Pressure is constantly applied to the rod side of the arm 13, and the stopper 14 attached to the bearing cover 15 is operated so as to come into contact with the block 17 provided at the lower end of the arm 13.

A guide roller 18 is attached to the upper end of the arm 13, and when the cylinder 2 acts with a certain stroke, the guide roller 18 has an arcuate surface whose radius is the distance between the axes of the shafts 4 and 7, and Either it starts to come into contact with the arcuate surface of the guide 19 provided on the shear body 1, or it moves away from the contact state.

When the guide roller 18 and guide 19 come into contact,
If the cylinder speed of cylinder 2 is high, it will generate an impact sound, so in order to absorb the impact energy, the guide 19
A cushioning rubber 21 is attached between the support base 20 and the support base 20.

The major feature of this device is that the movement of the cylinder 2, which is the root of all movements, is a rotational movement around an axis 4.
Due to the contact between the block 17 attached to the arm 13 and the stopper 14 attached to the bearing cover 15 fixed to the shaft 7, and the contact between the guide roller 18 and the guide 19, the shaft 7
Raise (or lower) the arm 9 fixed to the arm 9 almost straight upward (or lower) at a certain position. Specifically, change the arm 9 from the rotational movement of the arm 6 by the cylinder 2 to a linear movement, and To make a steel piece or a test piece 10 fall onto a conveyor without interfering with an obstacle 22.

FIG. 3 shows the steady state of the device. In this state, the cylinder 2 is in the O stroke, and the guide roller 18 and guide 19 of the arm 13 are in contact with each other due to the contraction of the cylinder 16. be.

The curve of the guide 19 is such that when the cylinder 2 goes in the direction of extension from the 0 stroke, the stopper 14 and the block 17
It is determined that the claw 11 attached to the arm 9, which is integrated with the shaft 7 by shrink fit, descends almost straight until it comes into contact with the shaft 7.

In the state shown in this figure, the claw 11 is raised to a position where it does not interfere with the threading of the rolled steel plate when there is no need to knock off the steel piece or test piece 10.

FIG. 4 shows that when the cylinder 2 is activated and the block 17 of the arm 13 comes into contact with the stopper 14 attached to the bearing cover 15 provided on the shaft 7 rotating via the arm 6, the guide roller 18 of the arm 13 indicates the moment when the guide 19 leaves the guide 19.

From the state shown in Fig. 3 to the state shown in Fig. 4, the claw 11 attached to the arm 9 descends almost straight down along the curved surface of the guide 19, and in the state shown in Fig. 4, it is attached downward. The guide plate 23 comes into contact with the upper surface of the guide plate 23, rotates about the pin 12, and becomes able to slide along the guide plate 23 surface.

In the state shown in FIG. 4, the claw 11 is attached to the steel piece or test piece
It goes without saying that it must be located just before 0.

When the cylinder 2 further increases its stroke from this state, the rotation of the arm 13 is regulated by the abutting relationship between the stopper 14 and the block 17, so that the arm 9 begins to rotate about the shaft 4.

FIG. 5 shows that the movement of the arm 13 is regulated by the abutting relationship between the stopper 14 and the block 17, the stroke action of the cylinder 2 changes the arm 9 into a rotational movement around the shaft 4, and the claw 11 is rotated against the steel piece or the test piece. The state from when the piece 10 is kicked to when it is finished is shown.

This layout 11 pushes the steel piece or test piece 10 while sliding along the surface of the guide plate 23, and is finished when the cylinder 2 reaches its full stroke.

At this time, the pawl 11 is adjusted by the liner 24 so that no gap is created between the pawl 11 and the guide plate 23.

FIG. 6 shows the state in which the steel piece or test piece is returned to its original position after being kicked.

The cylinder 2 is oriented in the direction of contraction from the full stroke, and the pawl 11 takes a return path along the guide plate 23.

In the state shown in this figure, the guide roller 18 of the arm 13 is in contact with the guide 19 at the same time as the stopper 14 separates from the block 17, and at this point,
The arm 13 is rotated about the axis 4 by the guide 19.
It changes to upward linear motion regulated by

In addition, in this state, there must be a space between the device and the obstacle 22 in front of it that will not cause interference.

If the speed of cylinder 2 is high, guide roller 1
When the guide 8 comes into contact with the guide 19, an impact sound is generated, but the impact sound is alleviated by the buffer rubber 21 which reduces the impact energy between the main body 1 and the guide 19.

FIG. 7 shows a steady position in which the cylinder 2 moves toward the O stroke from the state shown in FIG. 6, the guide roller 18 rises along the guide 19, and the cylinder 2 reaches the O stroke.

Since the movement of the arm 13 is regulated by the guide 19, the claw 11 attached to the arm 9 exhibits upward linear movement.

In this way, interference with the obstacle 22 in front of the device can be avoided since a constant distance is maintained.

During this series of operations, the cylinder 16 always applies pressure to the rod side, so the guide roller 18 and the guide 19 are in complete contact, or the stopper 14 and the block 1
7 acts to make complete contact.

As described above, according to the present invention, the rotational motion of the shaft 4 is converted into a linear motion and applied to the arm 9 via the arm 6 and the shaft 7, and from the end of this linear motion, the arm 6 is Arm 9
Touch to transmit the rotation of arm 6 to arm 9,
Articles can be transferred using the claw 11 at the tip of this.

In this way, since the arm 9 moves linearly in the vertical direction and then rotates, there is no need to make a large swing of the arm backwards as in the prior art shown in FIG. For example, when the present invention is applied to a shearing machine for rolled steel plates, a tensioning device for the rolled steel plates, etc. can be installed close to the shearing machine body, and product accuracy and product yield can be improved.

It also has the excellent feature that it can be widely used in transportation and transportation devices that utilize this device in limited spaces.
