Description

[Detailed Description of the Invention] The present invention relates to an apparatus for sorting and stacking paper sheets on either side.

Conventionally, this type of device has a detection unit that detects whether the front and back sides of paper sheets are uneven. However, when aligning either the front or the back, that work has traditionally been done manually.
Even when a part of the process is performed by a machine, the machine simply identifies the front and back sides using the detection unit, stacks each in a separate stacking unit (box), and then takes them out and stacks them manually. Therefore, it is similar that the work requires manual intervention.

Therefore, the purpose of the present invention is to provide a device that detects the front and back sides of paper sheets and stacks them on either side without requiring any human intervention.
In particular, a paper sheet sorting and stacking device that collects paper sheets from a hopper section that loads paper sheets, passes through a detection section that identifies the front and back sides of the paper sheets, and stacks them in a stacking box in alignment with front or back tickets. a pair of conveyance belts for conveying the paper sheets that have passed through the detection section while being held therein; and a sorting guide rotatably provided adjacent to the separated portion of each of the conveyance belts;
A pair of paper sheets connected to the pair of spaced apart conveyor belts to form a front ticket conveyance path and a back ticket conveyance path adjacent to the distribution guide in order to convey paper sheets that have passed through the sorting guide in different directions. In order to rotatably hold one end of each endless belt at a position adjacent to the distribution guide and to prevent each endless belt from joining with any conveyor belt other than the conveyor belt to be joined, the axial center positions of the endless belts are adjusted to each other. A double pulley section consisting of a pair of pulleys rotatably held on one shaft with different angles; and a pair of impellers configured to rotate in mutually different directions,
The object of the present invention is to provide a paper sheet sorting and stacking device in which the paper sheets that have passed through the detection section are arranged into front tickets or back tickets via the sorting guide, each of the conveyance paths, and each of the impellers. do.

Examples will be described below with reference to the drawings. In FIG. 1, a hopper section 2 on which paper sheets 1 are loaded;
a feeding section consisting of a feeding roller 3 and a separation roller 4 that feeds the paper sheets 1 one by one to the detection section 5;
Conveyor belts 6 and 7 that convey the sent paper sheets
A paper sheet processing machine according to the present invention is equipped with a detection unit 5 having a function of identifying the front and back sides of a paper sheet, and the paper sheet processing machine according to the present invention detects the front ticket (paper The front side of the leaf is facing up) and the back ticket (the back side of the leaf is facing up)
a distribution guide 18 that distributes the information to each conveyance path;
A front ticket conveyance path 9 that conveys the front ticket 8, a back ticket conveyance path 11 that conveys the back ticket 10, and a stacking section (accumulation box) that receives the front ticket 8 from the front ticket conveyance path 9 and holds it between blades.
An impeller 12 receives the back ticket 10 from the back ticket conveyance path 11 and transfers it to a collection box by pinching it between the blades, and scraping off the front ticket and the back ticket held by the impeller. It consists of a notch 15 at the upper edge of the collecting box 14 into which a blade is passed.

Next, to explain the operation of the device of the present invention, when the front ticket 8 passes the detection unit 5, the front/back detection signal from the detection unit 5 causes the distribution guide 18 to be activated before the front ticket reaches the distribution guide 18. Use an electromagnetic solenoid or other means to tilt it to the right (the position indicated by the solid line) as shown in Figure 2. The front ticket 8 is sent toward the front ticket conveyance path 9. The endless belt 20 of the ticket conveyance path 9 is in contact with the conveyor belt 7 and conveys the ticket 8,
The ticket is ejected between the blades of the impeller 12. The impeller 12 was constantly rotating in a clockwise direction, and the front ticket 8 was held by the blades and approached the upper edge of the collection box 14, and the front ticket 8 was held in the notch 15 as shown in FIG. When the blade passes, it is scraped off and accumulated on the accumulation receiving plate 16. The table tickets 8 are accumulated because the rotation of the impeller 12 is clockwise.
The front side faces upward as when passing through the detection section 5. When the back ticket 10 passes through the detection unit 5, the sorting guide is tilted to the left (the position indicated by the dotted line) before the back ticket 10 reaches the sorting guide 18.
The back ticket 10 is conveyed to the back ticket conveyance path 11 by the impeller 1
It is held between 3 wings. The impeller 13 rotates counterclockwise, and the blades holding the back ticket 10 move toward the collection box 1.
When passing through the notch 15 on the upper edge of 4, the back ticket 10
is scraped off and accumulated on the accumulation receiving plate 16.
Since the rotation of the impeller 13 is counterclockwise, the front side of the accumulated back tickets 10 faces downward in the opposite direction to that when passing through the detection unit 5. In the end, all paper sheets are stacked with the front side facing up in the stacking box. The stacking receiving plate 16 is lowered by a receiving plate lifter 17 using a spring 22 or the like as the weight of the paper increases, and is raised when the paper is removed.

Furthermore, as shown in FIGS. 2 and 4, the above-mentioned non-feed belts 20 and 21 are rotatable on a single crank-shaped shaft 23 provided with different axis positions. A pair of first pulley 24 and second pulley 25 are provided, which are held in the double pulley section 19 and are held in the same direction.
The first endless belt 20 suspended on the conveyor belt 6 is joined to the conveyor belt 6, and the second endless belt 21 suspended on the second pulley 25 is joined to the conveyor belt 7.

Therefore, the first pulley 24 and the second pulley 2
5 is configured such that the mutually held axial center positions differ by a distance indicated by the symbol D,
As described above, each banknote that is sorted in either direction by the sorting guide 18 and sent to the front ticket conveyance path 9 or the back ticket conveyance path 11 has its axial center position shifted, and 25 are shifted from each other, and either one of the endless belts 2
0 or 21, the outer periphery of the endless belt 20 or 21 on the opposite side is not on the same plane as there is a difference in level, and the banknotes to be transported are transported between the endless belt 20 or 21 on the opposite side and the outer circumference of the endless belt 20 or 21. belt 6 or 7
The tickets can be reliably conveyed through the front ticket conveyance path 9 or the back ticket conveyance path 11 without coming into contact with or getting caught in them.

In this embodiment, as shown in FIG. 1, the pair of conveyor belts 6 and 7 will be described in the form of a continuous pair of loops for the detection unit 5 and the respective conveyance paths 9 and 11. However, the present invention is not limited to the above-mentioned embodiments, and although not shown in the drawings,
A pair of endless conveyor belts is used corresponding to the detection section 5, and conveyance paths 9 and 11 are formed downstream of the detection section 5 in order to convey the paper sheets that have passed through the detection section 5. It goes without saying that the scope of the present invention also includes a case where a pair of endless conveyor belts are provided to convey the paper sheets 1 by providing one or more pairs of each conveyor belts 6 and 7.

In the embodiment described above, paper sheets with the front side facing up can be stacked, but it is also possible to stack paper sheets with the back side facing up by changing the front/back detection signal of the detection unit and the like.

Therefore, since the paper sheet sorting and stacking device according to the present invention is constructed as described above, front tickets or back tickets sorted from the sorting guide are passed through an endless belt formed by a pair of pulleys whose axes are shifted from each other. Thereby, a sheet sorting and stacking device can be obtained which can reliably transport sheets without interfering with each other and reliably stacks sheets by sorting the front and back sides of the sheets.
