Is set to a predetermined height so that the plate material 22 can be loaded. Further, the motors 16 and 16 'are continuously driven so that the left and right upper rollers 14 and 14' are rotated in opposite directions.
In the initial state of operation of the sorting apparatus 2, the left and right lower rollers 21 and 21 'are both positioned below the conveyor surface of the conveyor 5.

Then, the plate material 22 obtained by punching the strip plate with the press machine is conveyed by the conveyor 1 at a relatively short time interval, and its front end abuts the stopper roller 23 and stops. At this time, each belt 12 of the conveyor 1 continues to run in a state of slipping with respect to the plate material 22. Further, when the plate member 22 comes into contact with the stopper roller 23, a sensor (not shown) is activated and only the lower left roller 21 on the left side protrudes above the conveying surface of the conveyor 1 by the left air cylinder 20. At this time, the right air cylinders 20 'are not operated, and as a result, the right lower rollers 21' are maintained below the conveying surface of the conveyor 1. Then, the plate material 22 is lifted and separated from the conveyor 1,
As shown in FIG. 3, the left side portion of the plate 22 is the upper roller 14
And is held by each lower roller 21, and is distributed to the left side by the rotation of each upper roller 14. Even during this distribution, the upper rollers 14 'on the right side are continuously rotated in the opposite direction, and the plate material 22 is distributed while overcoming this frictional resistance while slightly contacting the upper rollers 14'. Become.

Further, the plate member 22 is guided by the guide plates 36 and 37 so as to be aligned in the front-rear direction of the plate member 22 and guide plates 28 and 29.
The plate member 22 is guided by being aligned in the left-right direction, dropped along the guide plates 28, 29, 36, 37 and placed on the pedestal 27. After allocating the plate material 22 in this way, the lower rollers 21 on the left side are lowered by the respective air cylinders 20 and returned to their original positions to prepare for the allocation operation of the next plate material 22.

If the counter (not shown) detects that the set number of plate materials 22 are loaded on the receiving table 27 by repeating the above-described operation, the left-side sorting work is completed, and the right-side sorting work is switched to.

That is, when the plate material 22 comes into contact with the respective stopper rollers 23, the sensor is operated, and only the right lower rollers 21 'are projected above the conveying surface of the conveyor 1 by the right air cylinders 20'. Is lifted and separated from the conveyor 1, the right side portion of the plate material 22 is sandwiched between the upper rollers 14 'and the lower rollers 21', and is distributed to the right side by the rotation of the upper rollers 14 '.

Thus, the left and right upper rollers 14, 14 'are always continuously rotated in the opposite directions, and the left and right lower rollers 21,
Either one of 21 'is selectively vertically raised, and the plate material 22 is sandwiched and distributed by the vertically raised lower roller 21 (or 21') and the upper roller 14 (or 14 ') opposed thereto. When changing the distribution direction of the plate material 22, it is not necessary to switch the rotation direction of the upper rollers 14 and 14 ', and it is possible to avoid wasting time associated with this switching of the rotation direction. In other words, the distribution direction of the plate material 22 can be switched by simply switching the drive of the left air cylinder 20 to the drive of the right air cylinder 20 '. As a result, it is not necessary to stop the operation of the conveyor 1 and the press machine when switching the distribution direction, and the productivity can be improved.

After a predetermined number of plate materials 22 are loaded on the receiving table 27, the table lifter 25 is lowered, and the plate materials 22 are moved on the roller conveyor 26 while being loaded on the receiving table 27 and taken out.

The present invention is not limited to the above-mentioned embodiment and various modes are possible. For example, the left and right upper rollers may be continuously rotated in opposite directions by a single motor via a gear train.

Further, it is possible to alternately operate a pair of motors intermittently. In this case, it is desirable to start driving the stopped motor with a time margin before switching the transfer direction.

(Effect of the Invention) As described above, in the present invention, the plate material is directly sandwiched between the lower roller on either side and the upper roller which is vertically opposed to the lower roller, and the plate material is distributed in the rotation direction of the upper roller. Therefore, the distribution direction of the plate material can be switched to the left and right in a short time, and the productivity can be improved.

Further, the upper roller is connected to a rotary drive system and is given a rotary drive function for distributing the plate materials, while the lower roller is rotatable and lifted to hold the plate material with the upper roller. Since the function is added and therefore both the rotation driving function and the lifting function are separated into the upper and lower rollers, the structure of the plate material allocating device is simple and it is of course possible to reduce failures. Since the left and right lower rollers are individually supported by the elevating function so as to be vertically vertically movable and rotatably supported, the plate material can be distributed to the right and left by individually and selectively moving up and down the lower rollers.
