The transport unit 2 according to an embodiment of the present invention is divided into the following four operations.

First, when the pallet P on which the strip S is placed is supplied from the outside to the stacking unit

The pallet P on which the strip S is placed is transported from the outside through a separate apparatus. For example, a separate apparatus can position the pallet P in the bottom support 211 of the input / output unit 21. [

As another example, the input / output unit 216 operates in a state where the input / output unit 21 faces the other device. Then, the pallet P is moved to the bottom support portion 211 of the input / output unit 21 in a state where the first input / output locking portion 214a is inserted into the second input / output locking portion P3. Thus, the input / output unit 21 can position the pallet P located in a separate device in the bottom support portion 211 of the input / output unit 21.

At this time, the thickness of the strip S can be detected through the thickness detector 251 in the pallet P positioned in the bottom support 211. When the pallet P is properly positioned on the bottom support 211, the first input / output locking portion 214a is inserted into and supported by the second input / output locking portion P3.

The pallet P positioned at the bottom supporting portion 211 at the initial position is operated by the control of the transportation control portion 252 in correspondence with the thickness of the detected strip S so that the lifting driving portion 236 is operated. Then, the elevation drive unit 236 moves the input / output unit 21 to the loading position of the pallet P.

After the input / output unit 21 stops at the loading position of the pallet P, the input / output unit 216 is operated by the control operation of the transportation control unit 252. [ Then, in a state in which the first input / output locking portion 214a is inserted into the second input / output locking portion P3, the input / output drive portion 216 moves the pallet P to the loading unit 1. When the pallet P is seated and supported in the right position of the loading unit 1, the entry / exit trajectory portion 214 is moved by the entrance / exit coupling portion 216 or the elevation driving portion 236 is operated, 214a are released from the second entry / exit securing portion P3.

Then, the elevation driving unit 236 is operated by the control operation of the transportation control unit 252 to return the input / output unit 21 to the initial position.

Second, when the pallet P loaded on the stacking unit 1 is discharged to the outside

The elevation driving unit 236 moves the input / output unit 21 to the position of the pallet P to be discharged when the elevation driving unit 236 is operated in the control operation of the transportation control unit 252 at the initial position. When the input / output unit 21 is positioned at the position of the pallet P to be discharged, the first input / output locking portion 214a is inserted into the second input / output locking portion P3. The first input / output coupling portion 214a is moved by the input / output trajectory portion 214 and inserted and supported in the second input / output coupling portion P3 in accordance with the operation of the input / output coupling portion 216 in a state where the input / .

Out port portion 216 is operated by a control operation of the conveyance control portion 252 so that the pallet P of the stacking unit 1 in the state where the first input / output locking portion 214a is inserted into the second input / output locking portion P3, Output unit 21 to the bottom support portion 211 of the input / The pallet P is then positively positioned on the bottom supporting portion 211 in a state where the first input / output locking portion 214a is inserted into the second input / output locking portion P3.

Then, the elevation driving unit 236 is operated by the control operation of the transportation control unit 252 to return the input / output unit 21 to the initial position.

And a separate device for discharging the pallet P may be provided outside. For example, a separate device may bring the pallet P positioned on the bottom support 211 to itself.

As another example, the input / output unit 216 operates in a state where the input / output unit 21 faces the other device. Then, the pallet P can be moved to a separate apparatus in a state where the first input / output locking portion 214a is inserted into the second input / output locking portion P3. Accordingly, the input / output unit 21 can send the pallet P positioned on the bottom support 211 to a separate device.

Third, when the pallet P loaded on the stacking unit 1 is delivered to the sorting and conveying unit 7

The pallet P mounted on the loading unit 1 is moved to the bottom supporting portion 211 at a predetermined position in the same manner as in the second case because the inlet and outlet opening portion 216 and the elevation driving portion 236 are operated by the control operation of the transportation control portion 252 And returns to the initial position.

The sorting and conveying unit 7 can be disposed below the lowermost pallet P corresponding to the loading position of the pallet P. [ The sorting bogie portion 71 of the sorting and conveying unit 7 is moved to the lower side of the pallet P.

The inlet / outlet unit 216 is operated in a state in which the inlet / outlet unit 21 is positioned so as to face the sorting and conveying unit 7. [ The pallet P can be moved to the sorting and conveying unit 7 in a state where the first input / output locking portion 214a is inserted into the second input / output locking portion P3. The input / output unit 21 can transmit the pallet P positioned in the bottom support portion 211 to the sorting and conveying unit 7. At this time, thickness information of the strip S that is seated on the pallet P can be transmitted to the sorting and conveying unit 7.

Fourth, when the pallet P seated on the sorting and conveying unit 7 is loaded on the stacking unit 1 or discharged to the outside

When the sorting bogie portion 71 of the sorting and conveying unit 7 is moved to the lower side of the pallet P at the lowermost end of the stacking unit 1 and the entrance / exit unit 21 is positioned to face the sorting / conveying unit 7 And the inlet / outlet opening portion 216 is operated. Then, the pallet P is moved to the bottom support portion 211 of the input / output unit 21 in a state where the first input / output locking portion 214a is inserted into the second input / output locking portion P3. The input / output unit 21 can correctly position the pallet P seated on the screening carriage 71 to the bottom support 211 of the input / output unit 21. [

At this time, the pallet P of the input / output unit 21 can be loaded on the loading unit 1 as the input / output port unit 216 and the elevation driving unit 236 are operated by the operation of the transportation control unit 252 as in the first case have. The pallet P of the input / output unit 21 can be discharged to the outside through the input / output unit 21 or another device as in the second case.
