Description

[Detailed description of the invention] This invention is suitable for vertically aligning and stacking steel plates, which are rolled into a coil and cut into predetermined dimensions, for example, used as a material for automobile bodies. Relating to a material stacking device.

For example, in an automobile body manufacturing factory, a coiled steel plate is cut into predetermined dimensions using a blanking press, and the cut materials (blank materials) are stacked using a stacking device. Conventionally, as shown in FIG. 1, the device has four side plates 4,4°4.4 divided into four parts, and a supporting member 5 is attached integrally or integrally to the lower part of each side plate 4. It has been proposed that the positions of the side plates 4, 4, . . . can be adjusted according to the dimensions of the material.

However, since the material inputted from the conveying device 3, which is installed at an angle and has guide rollers for feeding the material, hits the side plate 4, the side plate 4 is made to be considerably heavy so that the side plate can withstand the impact when the material is inputted. It is necessary to ensure that the position does not shift, and even if the side plate 4 is heavy, it will move slightly when the material is introduced, and this will cause the stacked end faces of the stacked materials to be uneven. For example, when using a vacuum suction tool, the topmost material There was an inconvenience that when the sheet feeder carried in the materials by suctioning them one by one, the loading position would be incorrect.

In addition, in order to take out the stacked materials, it is necessary to remove and set at least two side plates 4, 4 each time, which requires a lot of setup time, and the side plates are heavy, which increases the burden on the worker. there were.

The present invention was created in view of the above points, and aims to improve the stacking accuracy of materials by automatically aligning the end faces of materials introduced by their own weight from a conveying device installed at an angle. The purpose is to reduce the number of setup steps for workers.

A configuration of the present invention to remotely achieve such an object is to mount a pair of side guides facing each other on a base member so as to be able to approach and separate from each other, and to form a substantially right angle to the side guides. The first stopper and the second stopper face each other in between.
a stopper is mounted on the base member, and the material is placed from the second stopper side into the material storage space formed by the side guide and the first and second stoppers.
A conveying device for feeding the material toward the stopper is inclined and provided on the base member, and the first stopper is moved back by the impact when the material fed into the material storage space collides with the first stopper. , a material stacking device in which the first stopper is provided with a pressing means for pushing back the material after impact.

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

In FIGS. 2 and 3, reference numeral 10 designates a base member of the material stacking device, and the base member 10 has a substantially T-shaped overall planar shape.

Side guides 12 and 12 are erected on both sides of the support portion 11 extending to the central portion of the base member 10 so as to be parallel to and opposite to each other.

The spacing of the side guides 12.12 is adjusted according to the width of the material to be accommodated.

A first stopper 13 is disposed at the tip of the side guide 12 (the left side in the figure is the tip).

This first stopper 13 is connected to a rod 16 of a pneumatic cylinder 15, which is fixed to a holding member 14 placed on the base material 1° and serves as a pressing means. 13 is designed to move in the direction of arrow A.

Further, the holding member 14 is attached to rails 17 and 17 extending along both side edges of the support portion 11 of the base member 10.
8, it is supported so that it can run freely.

That is, the holding member 14 is moved in the direction of arrow B by a suitable drive device (not shown) or input, and the first stopper 13 is moved.
In addition to the positioning of the attached locking device 1
9 fixes the holding member 14 in a predetermined position.

On the other hand, a support frame 20 is attached to the base end of the side guide 12 on the opposite side to the side where the first stopper 13 is provided, and the support frame 20 is attached to a frame 22 connected to the side guide holding member 21 with pins. It is pivotally connected via 23.

Therefore, the side guide 12 rotates in a horizontal plane as shown by arrow X around the pin 23.

Further, the side guide holding member 21 is attached to the support portion 11.
Support frame 25.2 erected on support part 24 orthogonal to
By turning a handle 27 attached to the end of the screw shaft 26 in the direction shown by the arrow, the side guides 12 move toward and away from each other, that is, the direction shown by the arrow C. It will move in the direction.

In order to ensure the movement of the side guide 12, a roller 28 is provided at the bottom of the side guide holding member 21, and the roller 28 is placed on a rail 29 extending in the axial direction of the screw shaft 26.

On the other hand, a second stopper 30 is disposed on the base member 10 so as to be located on the proximal end side of the side guide 12 and to face the first stopper 13. 1 stopper 13 and the side guide 12
．． 12, I am self-disciplined about the material storage space.

The second stopper 30 is connected to a piston rod 32 of a cylinder 31 provided on the support portion 24.

Thereby, the position of the second stopper 30 relative to the first stopper 13 can be set depending on the dimensions of the material.

Further, a conveyance device 33 is provided on the base member 10 above the side guide holding member 21, that is, above the second stopper 30.

The conveyance device 33 has rollers 34 arranged in a row, and is located inclined downward toward the material storage space,
The material is introduced into the storage space toward the first stopper 13.

Next, the effect will be explained.

First, depending on the size of the material to be introduced, both side guides 1
2 interval is adjusted.

This is done by turning the threaded shaft 26.

Next, the distance between the first stopper 13 and the second stopper 30 is set to match the length of the material by moving the holding member 14 or driving the cylinder 31.

Then, a plurality of scripts are placed in the defined material storage space, and a single steel plate is placed on top of these bases to serve as the base of the pile of materials, completing preparations.

Subsequently, the blank materials cut by the planking bus machine are successively introduced into the material storage space via the conveying device 33.

At this time, the second stopper 30 is set at a predetermined forward position by the piston rod of the cylinder 31, and collides with the first stopper 13 every time one sheet of material is introduced.

Then, since a pneumatic cylinder 15 as a pressing means is attached to the first stopper 13, the first stopper 13 temporarily retreats by absorbing the impact of the material, but the pressure of the air compressed within the pneumatic cylinder 5 The restoring force moves forward and pushes the material back toward the second stopper 30 arranged oppositely.

In this way, all the front end surfaces of the materials that are sequentially introduced are aligned, and the stacking accuracy of the materials is improved.

When the stacking of materials is completed, the first and second stoppers 13
．． 30 and move the side guide 12.12 back to the pin 23.
Rotate in the horizontal plane as shown by arrow X around .

This allows the stacked materials to be taken out.

As described above, according to the present invention, the material introduced from the conveying device collides with the first stopper,
The first stopper is equipped with a pressing means such as a pneumatic cylinder, so when the material collides with the first stopper, the first stopper retreats due to the impact, but the pressing means causes the first stopper to move toward the second stopper. The material is pushed back, and the end faces of the stacked materials are brought together.

This improves the accuracy of stacking materials, ensuring that materials are always delivered to the correct position when loading them into the sheet feeder, and reduces the setup process for stacking positions and reduces the labor burden on workers. It has effects such as being
