Description

[Detailed description of the invention] This invention is designed to prevent irregularities when stacking paper sheets and to ensure that they are aligned in a machine that distinguishes, counts, and otherwise processes paper sheets. This invention relates to a paper sheet transport mechanism that transports paper sheets to a binding section, etc. without disturbing them.

For example, in a first inspection machine, which is a device that distinguishes whether paper notes are genuine or counterfeit notes, the paper notes that have been identified as genuine or fake are stacked on a paper stacker, and the number of sheets stacked is When the number of sheets reaches a certain value, the sheets are transported to the binding section.

In this case, the sheets must not be stacked unevenly, and the sheets must be transported without disturbing the alignment of the sheets.

The conveyance mechanism for this purpose generally includes a pair of upper and lower conveyor belts that pinch and convey the paper on the stacking table.

In the conventional type, as shown in FIG. 4, the conveying surface of the stationary lower conveying belt 1 is the receiving surface 2a of the paper stacking table 2.
When conveying paper waste, the upper conveyor belt 3 rotates around the pulley shaft 3a on the conveyance exit side.
The paper sheets stacked on the stacking table 2 are sandwiched between the upper conveyor belt 3 and the lower belt 1, and both belts are driven to convey them.

In this device, the lower belt 1 is located above the receiving surface 2a of the stacking table 2, so when the paper scraps fall from the stacker 4, the leading end catches on the lower belt 2, causing the paper scraps to be stacked unevenly. It becomes difficult.

In order to avoid this inconvenience, the lower belt 1 can be placed below the surface 2a of the stacking table 2, and the lower belt 1 can be raised to hold the paper, but this would result in a complicated structure. Become.

This invention was proposed in order to eliminate the above-mentioned conventional defects, and the purpose is to provide a paper sheet transport mechanism that has a simple structure and can transport paper sheets without irregularities.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 is a side view of the main part of the paper conveyance mechanism of the first inspection machine. The paper that has been discriminated as genuine or counterfeit by the discrimination section (not shown) is transferred to the stacking wheel 6 by the feed roller 5. 7, rotates together with the stacking wheel 6, hits the guide plate 8, falls, and is stacked on the stacking table 9.

This stacking table 9 has a notch 9b in a portion corresponding to a conveyor belt to be described later, and the base is attached to the guide plate 8 by a hinge 10.
The guide plate 8 is mounted so as to be rotatable downward, and is normally kept perpendicular to the guide plate 8 by a spring 11 that applies a force in the opposite direction.

The paper waste conveyance section that conveys the paper waste 12 stacked on the stacking table 9 is composed of a lower conveyance belt 13.13 and an upper conveyance belt 14.14.

The lower conveyor belts 13, 13 are provided below the surface of the stacking table 9, and normally do not come into contact with the paper.

The upper conveyor belt 14.14 has a pulley shaft 1 on the conveyor exit side.
It pivots downward about 7a, and as shown in FIG. 3, the lower conveyor belts 13, 13 sandwich the paper sheet 12.

The structure for feeding the upper and lower conveyor belts 13, 13, 14 and 14 and for rotating the upper conveyor belts 14 and 14 will be described.

The pulley shaft 1 of the lower belt 13, 13 is attached to the machine frame 15.15.
6a, 16b, and one pulley shaft 17a of the upper belt 14.14 is supported.

A gear 18 is fixed to the shaft 16a, and is rotationally driven by a motor 19 via a tuning band 20.

Further, a gear 21 is fixed to the shaft 17a, and this gear 21
meshes with the gear 18 having the same number of teeth, and the shaft 17a is rotationally driven.

An elevating side plate 22.22 is rotatably attached to this shaft 17a, and an upper belt 1 is attached to the end of this elevating side plate 22.22.
The other pulley shaft 17b of 4.14 is supported.

Pulleys 1 are located on the shafts 16a, 16b of the lower belt 13.13 and the shafts 17a, 17b of the upper belt 14.14 at positions corresponding to the notches 9a, 9b of the stacking table 9, respectively.
3a, 13a, 13b, 13b and 14a, 14a,
14b, 14b are fixed, and the aforementioned lower belts 13, 13 and upper belts 14, 14 are wound around these pulleys.

A gear 24.24 is fixed to the elevating side plate 22.22, and a gear 25.25 meshing with this gear 24 is fixed to a shaft 26 supported by the machine frames 15, 15.
is rotationally driven by a motor 27 via a tuning belt 28.

In the paper transport mechanism section of the first inspection machine configured as described above, when a predetermined number of paper sheets, for example 10 sheets, are stacked on the stacking table 9, the motor 27 is started and the gear meshing with the gear 25 is activated. 24, and the elevating side plate 22 integrated with this
Then, the upper conveyor belt 14 is rotated and lowered, and the paper 12 is sandwiched between the upper conveyor belt 14 and the lower conveyor belt 13.

Note that a protrusion 30 is attached to the pulley 29 of the shaft 26,
When this protrusion 30 blocks the photosensor 31, the upper conveyor belt 14 stops rotating and descending.

The mounting position of this photosensor 31 is 12
The upper belt 14 is predetermined so as to stop at an appropriate position for pinching.

Subsequently, motor 19 is started and gears 18, 21 are respectively
drive shafts 16a, 17a through both bells) 13.1
4 to convey the paper stack 12 toward the binding section.

The end of paper transport is detected by the photosensors 32a and 32b,
The motor 27 rotates in the opposite direction to that described above, and the upper conveyor belt 1
4 pivots upward and stops when the protrusion 30 blocks the photosensor 33.

Then, it is rotated upward by the spring 11 and returns to its original state.

In the above operation, when the waste paper falls from the stacking car 6 onto the stacking table 9 and is stacked, the lower conveyor belt 13 does not allow the paper waste to lie flat because the receiver of the stacking table 9 is located below the surface 9a. The supports fall directly onto surface 9a and are therefore stacked in alignment without any disturbance.

In this regard, in the conventional type, the lower conveyor belt 1 was placed above the surface, which tended to cause paper misalignment, but this has been greatly improved.

Further, when the upper conveyor belt 14 swings down and picks up the paper scraps 12, the stacking table 9
2, the lower conveyor belt 13
Even if the receiver is lower than surface 9a, there will be no problem in paper failure 1.
2 can be held in between, and the paper 12 will not be disturbed.

Furthermore, during conveyance, the upper and lower belts 13 and 14 are sufficiently sandwiched, so that no irregularities occur.

As explained above, this idea places the lower conveyor belt below the surface of the sheet stacking table, and also allows the stacking table to pivot downwards around its base so that it can return to its original position. Therefore, it has become possible to stack paper sheets in a way that does not cause misalignment, and it has also become possible to transport the paper sheets to a bundling section or the like without disturbing the alignment of the sheets.

Moreover, this is made possible by an extremely simple structure.
