The transfer means 3 has a suction tool 13 that can move back and forth, left and right, and up and down, and is used to suction and hold the plate-shaped object positioned by the means 2, and transfer and position it to the shearing machine 4. That is, the transfer means 3 is three-dimensionally controlled through a servo system, and 3a indicates a known servo device.

The shearing machine 4 cuts the plate-shaped body positioned by the means 3. The shearing machine 4 is equipped with a known sensor 4a for checking the cutting operation.
is provided.

The sorting means 5 has a take-out conveyor 14 which is tiltably provided by a tilting means 14a, and a shearing machine 4.
The cut plates are sorted into products and non-products. Note that the means 5 is provided with a known sensor 14b for checking the tilting movement of the conveyor 14.

The product storage means 6 are arranged at the end of the product conveyor 15 which is continuous with the conveyor 14 in its horizontal position. The stocking means 6 is formed of a shelf-like stocker 16, and the stocker 16 has a plurality of shelves 17 that can be moved up and down, and products can be stored on these shelves 17.

The transfer means 7 includes a reversing conveyor 18 which is provided below the conveyor 15 and is continuous with the conveyor 14 in the downward tilted position of the conveyor 14, and a conveyor stocker 8 (belt) which is provided below the shearing machine 4 and which is continuous with the conveyor 18. conveyor).
Further, a secondary material conveyor 11 is connected to the end of the stocker 8. Note that the conveyor 18, stocker 8, and conveyor 11 have their transfer amounts controlled via a servo system. 8a shows a known servo device of the stocker 8.

20 is a control means connected to each of the means 1 to 7 and the input device 21 via a bus line 20c, and is mainly composed of a central processing unit 20a and a memory 20b. The dimensions and procedure for cutting the plate-shaped object are inputted to the control means 20 in advance by the input device 21.
Therefore, the length of the secondary material plate 19 is as shown in the figure.
l ₁ , l ₂ , l ₃ are stored in advance, and their interval l ₀ is also stored in the same way. Based on these, the transfer amount of the conveyor stocker 8 is determined by a command from the control means 20 to the servo device 8a. In this way, the conveyor stocker 8 temporarily reserves the plate-like material 19 (secondary material) to be re-cut, which is supplied from the take-out conveyor 14 via the reversing conveyor 18, and stores the plate-like material 19 (secondary material) to be recut in relation to the shearing machine 4, etc. 19, the secondary material on the secondary material conveyor 11 is supplied to the positioning means 2 again in good time.

The operation of the control means 20 will be explained step by step with reference to the flowchart shown in FIG.

(1) First, the material on the material stocker 10 is transferred to the positioning means 2 by the material supply means 1 (procedure
_P1 ).

(2) Next, the operation confirmation sensor 1a confirms that the plate has been sent, the positioning means 2 positions the plate, and the operation confirmation sensor 2a confirms this positioning. The shaped body is held by the transfer means 3, the position of the shearing machine 4 is controlled by the servo device 3a according to the cutting dimension, and the shearing machine 4 is operated to cut it (procedure).
_P2 ).

(3) The operation confirmation sensor 4a confirms the cutting, and it is determined whether the plate-shaped body that has just been cut is a secondary material or not (Step P ₃ ). This is input into the control means 20 in advance to store whether or not the plate-shaped bodies to be successively cut are secondary materials.

(4) If it is a secondary material in step P ₃ , the take-out conveyor 14 is tilted by the tilting means 14a and the secondary material is sent toward the conveyor stocker 8 (step P ₄ ).

(5) The length of the secondary material in step _P4 (previously stored in the control means 20) and the distance l ₀ between the secondary materials (also stored in advance) are the same as the length of the conveyor. The secondary material on the claw 8 is transferred by a command to the servo device 8a (procedure P ₅ ).

(6) On the other hand, if it is determined in step _P3 that it is not a secondary material, the cut plate is sent to the product storage means ₆ (step P6).

(7) After steps P ₅ and P ₆ , it is determined whether all the cutting processes for the plate-shaped object currently held in the transfer means 3 have been completed (step P ₇ ).

(8) If so in step P ₇ , determine whether there is secondary material on the conveyor stocker 8 (step
_P8 ). This judgment can be made by the control means 20 based on the results of the operations up to now.

(9) If there is, only one secondary material is transferred onto the secondary material conveyor 11 (step P ₉ ). At this time as well, the arrangement of the secondary materials on the conveyor stocker 8 is determined by the control means 20 and the transfer amount is commanded.

(10) Transfer the secondary material on the secondary material conveyor 11 to the positioning means 2 by the material supply means 1 (procedure
_P10 ) Return to step _P2 .

(11) If this is not the case at P ₈ and there is no secondary material on the conveyor stocker 8, it is determined whether all cutting work has been completed (Step P ₁₁ ). If so, this program will be terminated. If not, return to step _P1A .

As mentioned above, in the automatic shearing device, not only the conveyor stocker 8 but also all operations are controlled by the control means 2.
0 and is automatically performed according to registered commands.

Therefore, according to the conveyor stocker of the present invention as described above, the transfer, stop, and transfer amount are controlled by the control means, and the plate-like objects are processed in the processing order in cooperation with each means of the plate-like object processing device. By temporarily retaining the material until it becomes available and supplying it at the right time, it is possible to minimize the waiting time of the plate processing machine and significantly improve the operating rate, as well as improve work efficiency and safety. , it has various excellent advantages such as being able to simplify the overall structure by adding a conveyor stocker function for conveyance.
