The operation of the conveying device (1) for the superposed paper sheets (P) according to this embodiment having the above-mentioned structure will be described with reference to FIGS. 2 and 3.

When the superposed paper sheet (P) is pulled in, the motor (5) rotates in the normal direction (direction of arrow X in FIG. 2) and the third pulley (13) engages with the first driven shaft (8). Then, the third pulley (13) is rotated in the direction of the arrow.

The rotational force of the third pulley (13) is transmitted to the first idle wheel (18) via the second belt (19). At this time, the one-way clutch (38) of the fourth pulley (14) is not engaged and is in an idling state (engaged and rotated only when rotating in the direction of the arrow shown by the dotted line). Therefore, the superposed paper sheet (P) is sandwiched between the fourth pulley (14) and the second belt (19), but it is moved in the same direction as the conveying direction of the second belt (19). 4 pulleys (1
4) only idles, and is substantially conveyed by the second belt (19) by the rotational force of the third pulley (13).

At this time, the laminated paper sheet (P) sandwiched between the fourth pulley (14) and the second belt (19) is
Since the curvature on the front surface (P1) side in contact with the fourth pulley (14) is smaller than that on the back surface (P2) side, the speed on the back surface (P2) side is higher than that on the front surface (P1) side.

When the superposed paper sheet (P) reaches the conveying position shown by the solid line in FIG. 3, when the motor (5) is rotated in the reverse direction (direction of arrow Y in FIG. 3), one of the fourth pulley (14) is moved. The directional clutch (38) is engaged and brought into engagement with the second driven shaft (9), and the fourth pulley (14) becomes a drive pulley and is rotated in the arrow direction.

At this time, the one-way clutch (37) of the third pulley (13) is disengaged and is in an idling state (engaged and rotated only when rotating in the direction of the arrow shown by the dotted line). Therefore, the drive belt is switched from the second belt (19) to the third belt (20). Therefore, the superposed paper sheet (P) is in a state of being sandwiched between the third pulley (13) and the third belt (20), but it is different from the conveying direction of the third belt (20). 3rd in the same direction
The pulley (13) of FIG. 3 simply idles, and is substantially conveyed by the third belt (20) by the rotational force of the fourth pulley (14), and the laminated paper sheet (P) is indicated by the alternate long and short dash line in FIG. It is discharged from the transport device (1) as indicated by.

At this time, the laminated paper sheet (P) sandwiched between the third pulley (13) and the third belt (20) is
Since the curvature of the back surface (P2) side in contact with the third pulley (13) is smaller than that of the opposite surface (P1) side, the front surface (P
The speed on the 1) side becomes faster than that on the back surface (P2) side.

That is, for example, if the speed difference generated between the front surface side and the back surface side of the superposed sheet (P) by the fourth pulley (14) at the time of normal rotation of the motor (5) is positive, then at the time of reverse rotation. Since the speed difference between the front surface side and the back surface side of the superposed paper sheet (P) due to the third pulley (13) is negative, the speed difference is canceled (absorbed) by both.

FIG. 4 is a plan view of a stacking sheet conveying device showing a second embodiment of the present invention, FIG. 5 is a sectional view taken along the line AA, and FIG. 6 is a sectional view taken along the line BB. The same parts are designated by the same reference numerals and the description thereof will be omitted.

In the second embodiment, the third pulley (13) and the fourth pulley (13a, 13b) and (14a, 14b), which are two in the first embodiment, are integrally formed.
Of the third pulley (39) and the fifth pulley (40), which are separate bodies, and the fourth pulley (41) and the sixth pulley (41).
This is different from the pulley (42) in FIG.

With this change, the pulleys (39, 4)
0, 41, 42) has the following configuration. The fifth pulley (40) and the sixth pulley (41) each have two rolling bearings (43, 44) and (45, 48), respectively.
Are rotatably supported by the first driven shaft (8) and the second driven shaft (9) respectively, and the third pulley (39) and the fourth pulley (42) are each one rolling bearing. (4
7,46) with a first driven shaft (8) and a second driven shaft (9)
It is rotatably supported by.

The fifth pulley (40) is engaged with the one-way clutch (4) which is engaged only when the motor (5) is rotating normally.
9), the sixth pulley (42) is provided with a one-way clutch (50) that engages only when the motor (5) is in reverse rotation.

The second belt (19) is always in contact with the ridges of the third pulley (39), the sixth pulley (42) and the first idler wheel (18), and is wound. The belt (20) of No. 3 has a fourth pulley (41) and a fifth pulley (4).
0) and the first mountain (17) are wound in contact with the respective mountains, and are respectively wound and transmitted under predetermined conditions.

Conveying device (1) in the second embodiment
The operation will be described with reference to FIGS. 5 and 6. When the superposed paper sheet (P) is pulled in, the motor (5) reversely rotates (direction of arrow X in FIG. 5), the one-way clutch (50) of the sixth pulley (42) is engaged, and the second driven member is driven. The sixth pulley (42) is rotated in the direction of the arrow via the shaft (9), the sixth pulley (42) becomes a drive pulley, and the second belt (19) becomes a drive belt.

At this time, the third pulley (39) does not have a one-way clutch and is in an idling state. Then, the rotational force of the sixth pulley (42) is transmitted to the second belt (19) and the sixth pulley (42) and the second belt (19) are rotated.
The superposed paper sheet (P) drawn between the belts (19) is conveyed by the rotational force of the sixth pulley (42).

At this time, the laminated paper sheet (P) sandwiched between the sixth pulley (42) and the second belt (19) is
Since the curvature on the front surface (P1) side in contact with the sixth pulley (42) is smaller than that on the rear surface (P2) side, the speed on the rear surface (P2) side is higher than that on the front surface (P1) side.

When the superposed paper sheet (P) reaches the carrying position shown by the solid line in FIG. 6, when the motor (5) is rotated in the normal direction (direction of arrow Y in FIG. 6), the fifth pulley (40) moves. The one-way clutch (49) is engaged, the fifth pulley (40) is rotated in the arrow direction through the first driven shaft (8), and the fifth pulley (40) becomes a drive pulley, The third belt (20) becomes a drive belt.

The fourth pulley (41) has no one-way rotation clutch and is in a free state. Further, the rotational force of the fifth pulley (40) is the third
The third belt (20) transmitted to the belt (20) of
The laminated paper sheet (P) is passed through the fifth pulley (4
Due to the rotational force of (0), it is discharged from the carrier device (1) as shown by the chain line in FIG.

During this discharging and conveying, the fifth pulley (40)
The laminated paper sheet (P) sandwiched between the third belt (20) and the third belt (20) has a back surface (P) in contact with the fifth pulley (40).
Since the curvature on the 2) side is smaller than that on the surface (P1) side,
The speed on the 1) side becomes faster than that on the back surface (P2) side.

That is, for example, if the speed difference generated by the sixth pulley (42) between the front surface side and the back surface side of the laminated paper sheet (P) when the motor (5) is rotated in the reverse direction is positive, Since the speed difference between the front surface side and the back surface side of the superposed paper sheet (P) by the fifth pulley (40) becomes negative, the speed difference between them is canceled (absorbed).

The operation of each of the above embodiments can be controlled by, for example, a one-chip microcomputer in which the operation sequence is stored in advance.

[0043]

As described above, according to the present invention, since the rotating and superposed sheets are conveyed while repeating the forward and reverse rotations of the motor, the speed difference due to the use of the pulley having the small curvature can be absorbed, and the superposed sheets can be superposed. Do not cause local misalignment on the laminated paper sheet and cause it to occur on the laminated paper sheet. Therefore, there is an effect that it is possible to smoothly convey the superposed paper sheet without causing misalignment, wrinkle, jam, and the like.
