The width of the sheet sent from the horizontal folded section 1 onto the conveyor belt 9 is detected by the width detecting means 51. Now, when the wide width sheet having the width W2 is detected by the width detecting means 51, the detection signal is sent to and stored in the control device. And
If the preceding sheet does not exist between the width detecting means 51 and the gate 23, that is, the preceding sheet has already been carried out by the carry-out device 25.
Alternatively, when it is stored in 38, the journaling / laminating machine 36 is in a state in which the carriage 41 is retracted to the outside of the machine frame 37 to receive the wide sheets. In this case, when the preceding sheet is a wide sheet, the carriage 41 is in the retracted position, and therefore does not operate as it is. Then, when the narrow sheet is ahead and the carriage 41 is located in the machine frame 37, the control device switches the control valve of the pneumatic cylinder 47 to retract the piston rod of the pneumatic cylinder 47 to move the carriage 41. Evacuate out of the machine frame 37. Even during this period, the conveyor belt 9 conveys the wide sheets, and when the wide sheets come to the position of the lift 14, the arm 1 moves.

The sheet ends are clamped between the belts 32 and 33 at a and are sandwiched by the belts 32 and 33 that move in the direction of the arrow shown in the drawing, and the sheets are conveyed until they pass the pulleys 28 and 30 positions. Belt 32 moving in the direction
Send the sheets in the direction of the arrow. When the leading edge of the sheet is detected by the leading edge detection sensor 20, the signal is sent to the control device,
The control device urges the drive device that drives the swing shaft 24 to rotate the swing shaft 24, open the closed gate 23 in a double-door manner, and drop the sheet. Since there is no obstacle such as the carriage 41 on the locus where the sheets fall, the sheets are loaded on the first unloading device 25. Gate 23 closes as soon as the sheets fall after opening. When the width detecting means 51 detects that the sheet to be sent next is a wide sheet, the trolley 41 kept in the above state remains retracted.

Here, when the narrow width W1 sea is detected at the position of the width detecting means 51 and the preceding wide width sheets are stacked, the signal of the width detecting means 51 switches the control valve of the pneumatic cylinder through the control device. Then, the piston rod of the pneumatic cylinder 47 is moved forward, and the carriage 41 enters the machine frame 37 and stands by. The narrow sheet comes through the conveyor belt 9 and the conveyor 171 onto the closed gate 23, and the leading edge is detected by the leading edge detection sensor 2
When the signal is detected at 0, the signal opens the gate 23, the narrow sheets are stacked on the second unloading device 38, and the gate 23 is closed. If the sheets to be sent next are narrow, the cart 4
No. 1 is immovable without changing the position in the machine frame 37, and when the width is wide, the dolly 41 is retreated to the outside of the machine 37.

Thus, when the control device counts that a predetermined number of sheets has been loaded on either of the unloading devices 25 and 38, the unloading device 25 or 38 that has loaded the predetermined number of sheets is driven, and the sheets move to the belt conveyor 26 or 44. It is transferred to and shipped out. As a result, the sheet bundle carried out by the belt conveyor 26 has only wide sheets, and the sheet bundle carried out by the belt conveyor 44 has only narrow sheets, so that the sheets can be bound as they are, so that the bundling machine can be automated. Can be delivered to.
