The second roller holding base 59-2 is lowered so as to be located below.

Then, when the leading end of the plate-like component P conveyed by the first conveyor 1 moves to the first roller holding table 59-1, the plate-like component P is rotated by the rotation of the first roller 51. First
The plate-shaped component P is transferred onto the first roller holding table 59-1 because it is drawn onto the roller holding table 59-1.

When the plate-like part P is transferred to the first roller holding table 59-1, the second roller holding table 59-2 is raised. When the second roller holding base 59-2 moves up, the second roller 52 moves the plate-shaped component P to the first roller holding base 59-1.
Is lifted above the upper surface of the plate to cut off the contact between the plate-like part P and the first roller 51.

At the same time, the rotation of the second roller 52 causes the plate-shaped component P to be sent toward the second conveyor 2,
Finally, the plate-shaped component P is transferred to the second conveyor 2.
When this transfer is completed, the second roller holder 59-2 descends,
The preparation for receiving the next plate-shaped component P from the first conveyor 1 is completed.

[0024]

According to the first aspect of the invention, the first roller is inclined by 45 degrees with respect to the traveling direction of the first conveyor, and the second roller is orthogonal to the first roller. Initially, both of them rotate in a direction in which there is a component force for pulling the plate-shaped component onto the roller holder.

Therefore, the component force of the first roller for moving the plate-shaped component toward the second conveyor and the plate-shaped component being moved to the second
The component force of the second roller that moves in the opposite direction to the conveyor is substantially canceled.

Then, both component forces in the sensor direction, that is, when the plate-shaped component is pulled into the roller holding base, are combined. Therefore, the plate-shaped component is drawn straight onto the roller holding table. Next, when the plate-like parts have been transferred onto the roller holding table, the second
Rollers rotate in reverse. As a result, the component force of the first roller that moves the plate-shaped component in the sensor direction and the component force of the second roller that moves the plate-shaped component in the first conveyor direction are substantially offset. Then, both component forces for sending the plate-shaped component toward the second conveyor are combined. Therefore, the plate-shaped component is sent straight to the second conveyor.

In the second invention, the first roller group 21 is inclined by 45 degrees with respect to the traveling direction of the first conveyor, and the second roller groups are orthogonal to each other with the first roller group sandwiched therebetween. .. That is,
Since the number of rollers in contact with the back surface of the plate-shaped component is large, a strong feeding force is applied to the plate-shaped component.

On the other hand, when the plate-like component is pulled into the roller holding base, it is in the lowered position, and the guide roller 25 which rises when the plate-like component is transferred to the roller holding base is held by the first conveyor and the roller holding base. It is arranged between the table and the table.
In addition, the fixed guide rollers 26 arranged along the side edge of the roller holding base on the side opposite to the second conveyor, and the other fixings arranged along the side edge of the roller holding base on the side opposite to the first conveyor. A guide roller 27 is provided. Each of the guide roller and the fixed guide roller is mounted so as to be rotatable around a vertical axis.

Therefore, when the plate-shaped component is transferred from the first conveyor to the transfer conveyor, the component force of the first roller group that moves the plate-shaped component toward the second conveyor and the plate-shaped component is moved to the second conveyor.
The component force of the second roller group that moves in the direction opposite to the conveyor is not canceled out, and the plate-like component may be pulled in the diagonal direction with respect to the roller holding base.
Since the fixed guide roller 26 serves as a guide, the plate-shaped component moves straight in the sensor direction.

Further, when transferring from the transfer conveyor to the second conveyor, the component force of the first roller group for moving the plate-shaped component in the sensor direction and the plate-shaped component in the first conveyor direction are moved. The fixed guide roller 27 and the guide roller 25 serve as guides even if the plate-shaped component moves diagonally with respect to the second conveyor without canceling out the component force of the second roller group. Therefore, the plate-shaped component moves straight in the direction of the second conveyor.

According to a third aspect of the present invention, a roller group is provided on the roller holding base, the rotating shafts of which are rotated by 45 degrees with respect to the traveling direction of the first conveyor, and the plate-shaped parts are arranged on the roller holding base. In the case where the plate-shaped component is moved down to the roller holder, the guide roller 35 is arranged between the first conveyor and the roller holder when the plate-shaped component is lowered. Further, the fixed guide rollers 36 arranged along the side edge of the roller holding base on the side opposite to the second conveyor, and the other fixings arranged along the side edge of the roller holding base on the side opposite to the first conveyor. A guide roller 37 is provided.

Therefore, when the plate-shaped component is transferred from the first conveyor to the transfer conveyor, the roller group acts in a direction in which the plate-shaped component is moved obliquely with respect to the roller holding base, but the fixed guide roller is used. Since 36 serves as a guide, the plate-shaped component moves straight toward the sensor.

Further, when transferring from the transfer conveyor to the second conveyor, the roller group acts in a direction to move the plate-like component in an oblique direction with respect to the second conveyor. Since the roller 35 serves as a guide,
The plate-shaped component moves straight in the direction of the second conveyor.

Also in the fourth aspect of the invention, the respective guide rollers and fixed guide rollers fulfill the same function.

It should be noted that when the plate-shaped component P is completely transferred to the second conveyor 2, it rotates normally.

More specifically, since the rotation axis of the first roller 11 is parallel to one diagonal line of the roller holding base 19, the second roller 12-2 of the roller holding base 19 will rotate when rotated as shown by the solid line.

On the other hand, by rotating the second rollers 12-1 and 12-2 in the forward direction as shown by the solid line, the plate is formed at the corner of the first roller end side farther from the first conveyor 1. A force that moves the component P obliquely works. In addition, by rotating the second rollers 12-1 and 12-2 in the reverse direction as shown by the dotted line, the plate-shaped component P is provided at the corner of the first roller end side closer to the first conveyor 1. The force to move it diagonally works.

Therefore, when the plate-shaped component P is sent out from the first conveyor 1 to the roller holding table 19, the component force of the first roller 11 for moving the plate-shaped component P toward the second conveyor 2 and , The component force of the second rollers 12-1 and 12-2 for moving the plate-shaped component P in the direction opposite to the second conveyor 2 is almost canceled, and the plate-shaped component P is sent to the sensor 8 in both directions. The component forces are combined. Therefore, the plate-like part P should be straight on the roller holder.
Pulled over 19.

When the plate-like part P has finished moving on the roller holding table 19, the second rollers 12-1 and 12-2 rotate in the reverse direction.
Then, the component force of the first roller 11 that moves the plate-like component P in the sensor 8 direction and the component force of the second rollers 12-1 and 12-2 that move the plate-like component P in the first conveyor direction. And are almost canceled out, and both component forces for sending the plate-shaped component P in the direction of the second conveyor 2 are combined. Therefore, the plate-like component P moves straight toward the second conveyor 2 and is transferred to the second conveyor 2.
