The working steps of the apparatus of the present invention will be described based on this. First, a large number of sheets P for aligning the sheets are stacked on the table 2 of the feeder A and the main power source is turned on. Then, when the size of the paper P is input according to the instruction of the operation panel 118, the fork 1 on the side of the supply device A transfers the paper P via the guide plate 14 to the stacking device B.
And the stacking device B
Side front guide ruler plate support arm 94 and right lateral guide ruler plate support arm 109 adjust the size by advancing or retracting according to the size of the sheet P, and the fork 53 on the stacking device B side supplies the device. Ascending to a position where the first sheet of paper P transferred from the A side can be stacked, and operating the forward / backward tilt hydraulic device 26 to tilt the entire stacking device B backward, and then the left / right tilt hydraulic device. 37 is actuated to further tilt the stacking device B to the rear side and further tilt it to the left side, and the table 54 on which the sheets P transferred from the supply device A are stacked is set to the rear side and the left side. Hold down while leaning down. This completes the preparation for transferring the paper P from the supply device A side to the stacking device B. The inclination angle of the table 54 to the rear side is preferably about 8 degrees and the inclination angle to the left side is about 8 degrees.

After the preparation is completed, an operator rides on a workbench (not shown) arranged on the rear side of the feeding device A, and the leading end portion of a predetermined number of sheets P is moved to the air cylinder 12 of the biting device 3.
Is operated to bite between the holding plate 10 and the holding plate 13, and the biting device 3 is moved onto the stacking device B via the guide rail 4. The sheet P is transported to the table 54 along the guide plate 14 while being bitten by the bite device 3, and the front of the guide plate 14 is formed on the slope portion 15 so as to match the inclination of the table 54. Because of the presence of the sheet P, the transfer operation of the sheet P can be performed smoothly. In the meantime, the fork 1 on the side of the feeder A moves up by the height of the transported paper P.

Immediately before the sheets P are stacked on the table 54, the front guide ruler plate 99 and the right lateral guide ruler plate 114 are slightly retracted by reversely rotating the motors 85 and 105, respectively, and are transferred onto the table 54. The discharged paper P is moved to the table 5 by operating the air cylinder 12 of the bite device 3 to release the bite state.

Vibration is applied to the two sides of the rear side surface and the left side surface of the sheet P while keeping contact with each other. As a result, since the entire table 54 is tilted to the rear side and the left side surface side, the entire sheet P is moved to the rear side and the left side surface side while being vibrated, and the sheet P stacked on the table 54 is moved. By accurately aligning the two sides of the rear side surface and the left side surface, the remaining two sides are naturally aligned, and the sheet aligning work of the sheets P stacked on the table 54 at the first time is completed. The left lateral guide ruler plate 80, the front guide ruler plate 99 and the right lateral guide ruler plate 114 are attached to the mounting shafts 79,
Since it is swingably fixed to the tips of 98 and 113 and is pressed in the direction of the paper P by the pressing springs 81, 100 and 115, it is possible to adapt to the inclined state of the paper P.

Next, the paper alignment work of the paper P transferred to the stacking device B after the second time will be described. Immediately after the first paper P alignment operation is completed and the second paper P transfer operation is started, the paper retainer / air blowing plate 72 is immediately pressed.
Moves forward from the recessed portion 70 of the vertical guide ruler plate 67, drops onto the rear end portion of the paper P after the completion of the first paper alignment work, and comes into pressure contact with the air from the outlet 74. Air is fed onto the paper P. After that, the paper P is further stacked on the paper P stacked on the table 54 by the bite device 3 as in the first time. During this time, the rear end portion of the first-time sheet P is pressed by the sheet-holding / air-blowing plate 72, so that the stacked sheets P are prevented from being displaced and air is blown from the blow-out port 74 at the first time. Paper P
Air is sent to the upper side to form an air curtain, and the already stacked first sheet P and newly stacked second sheet P
And the alignment of the paper P are further improved. Then, when the sheets P of the second time are piled up, the sheet pressing / air blowing plate 72 moves up and retracts to the rear of the vertical direction guide ruler plate 67, and the subsequent aligning work of the sheets P is the same as that of the first time. Further, the alignment work from the third time onward is also the same as the second time.

When the sheets P having a predetermined height are piled up on the table 54 by the paper alignment work, the work is completed, and when the operation completion button on the operation panel 118 is pressed, the left and right tilt hydraulic devices 37 and the front and rear tilt hydraulic devices 26 are pressed. Is activated to return the stacking apparatus B to the original position in the horizontal state, the front guide ruler plate 99 and the right lateral guide ruler plate 114 are also retracted and returned to the original position, and the fork 53 is also lowered to the original position. On the other hand, the fork 1 on the supply device A side is also lowered to return to the original position, and the operation of the device of the present invention is stopped by turning off the main power supply.

After the operation of the apparatus of the present invention is stopped, the table 54 on the fork 53 on which the sheets P for which the alignment work on the stacking apparatus B has been completed is stacked by a forklift or a handlift is transferred to a printing machine or the like. . When the paper alignment work is continued again, the above work is repeated.

[0040]

Since the present invention is as described above, the sheets transferred from the side of the feeder to the stacking device are stacked on the table inclined rearward and to the left side, and Forcibly inclines according to the inclination, and its four sides contact the vertical guide ruler plate, the left lateral guide ruler plate, the front guide ruler plate, and the right lateral guide ruler plate respectively, and the vertical guide ruler plate and the left lateral guide ruler plate. Vibration is applied by the vertical vibrator and the left lateral vibrator attached to the ruler plate, and the two sides of the rear side and the left side of the paper are aligned, so that the other two sides are automatically aligned. When the paper is further transferred from the feeding device to the stacking device on the paper for which the aligning work is completed, the rear end face of the paper already stacked on the table is pressed by the paper pressing and air blowing plate, and the air is blown. By feeding the air onto the paper from the outlet, it is possible to prevent the already stacked paper from being flipped or lifted, and to smoothly carry out the work of stacking the newly stacked paper. Also, every time the paper is transferred from the feeder side and stacked on the table of the stacking device, the infrared sensor detects the stacking height, and the fork on the stacking device side is moved by the stacking height. Since the height of the table that descends and always stacks the sheets transported from the feeder side is constant, the transported sheets can be placed gently without dropping on the table.
