The guide member has a cylindrical shape having substantially the same diameter as the transport roller,
A plurality of grooves are formed in the outer peripheral portion, and the distribution member is provided with a plurality of protrusions corresponding to the plurality of grooves of the guide member in a comb-like shape, thereby forming a plurality of protrusions with the grooves of the guide member. A nested structure is formed between them.

(Operation) According to the paper sheet sorting and stacking apparatus having the above-described configuration, the required number of concave grooves provided on the outer peripheral portion of the cylindrical guide member having substantially the same diameter as the transport roller and the comb-like shape of the sorting member are provided. Since the protruding portions of the rotating pieces arranged in a line form a nested structure, when each rotating piece is turned to the guide member side, there is no obstacle in the passing area of the sheets and the conveying direction of the jammed sheets. Regardless of
Jam processing can be performed simply. Further, since the transport roller and the guide member are coaxially configured, an effect that the jam processing can be performed more reliably is obtained.

(Example) Hereinafter, an example of the present invention will be described in detail.

A paper sheet sorting and accumulating apparatus 1 shown in FIG. 1 includes a paper sheet supply unit 10 for supplying loaded stacked paper sheets (hereinafter referred to as banknotes P) one by one to a next-level device, A paper sheet inspection unit 20 for discriminating whether or not various kinds of banknotes P supplied from the supply unit 10 are stacked, whether or not a cellophane tape is attached, discrimination of denominations, true / false audits, damage inspections, etc. A transport path 30 including first to third transport sections (transport means) 30a, 30b, 30c for transporting various kinds of banknotes P passing through the section 20 to the next apparatus, and bills transported on the transport path 30 A sorting gate 40 as a plurality of sorting means for sorting Ps into denominations based on a signal from the paper sheet inspection unit 20, and first to thirty storages of the banknotes P sorted by the sorting gates 40 by denomination. And a sorting stack 50 made up of third sorting boxes 50a, 50b, 50c.

The transport path 30 includes a banknote P that has passed through the paper sheet inspection unit 20.
Transport section 30a for guiding the upper part of the container, and the respective sorting boxes 50a, 50
b, 50c and the reject assembly 50r
Transport section 30b, the first transport section 30a and the second transport section 30
and a third transport unit 30c that communicates with b.

As shown in FIG. 2, each of the sorting boxes 50a, 50b, and 50c is provided so as to be openable and closable so as to cover a box-shaped main body 51 for accumulating and storing bills P and an opening of the main body 51. Lid 52
Further, a magnetic member 52a is attached to the protruding end side of the lid 52.

The distribution gate 40 is attached at a predetermined interval to a shaft 44 disposed in a direction perpendicular to the direction of transport of the banknote P by the second transport section 30b, as shown in an enlarged manner in FIG. For example, a total of four comb-tooth-shaped sorting members attached at predetermined intervals to a medium-high transport roller 43 for transporting the banknote P in a three-piece configuration and a rotating shaft 45 arranged in parallel with the shaft body 44.
42, four guide members 41 coaxially arranged with the transport roller 43 and opposed to the distribution members 42, respectively, and a motor 46 for driving the rotation shaft 45 to rotate.

Each of the guide members 41 has a columnar shape having substantially the same diameter as each of the transport rollers 43, and has an outer peripheral portion in a direction perpendicular to the shaft body 44.
The plurality of concave grooves 41a are formed.

The distributing member 42 includes three turning pieces 42a having protrusions 42b which can be immersed in the respective concave grooves 41a of the guide member 41.
It is configured to be arranged in a comb shape corresponding to the interval of a.

In the paper sheet sorting and accumulating apparatus 1 as described above, the paper money P may be jammed in the transport path 30 while the paper money P is being transported.

In this case, the rotation shaft 45 is rotationally driven by the motor 46 so that the projection 42b of the rotation piece 42a of the distribution member 42 is moved into the concave groove 41a of the guide member 41 as shown in FIG.
Immerse yourself in Accordingly, there is no obstacle in the transport area of the bill P, and the bill P is
It is guided along the outer circumference of the circle adjacent to 41a and passes without hindrance.

As a result, the paper money P removal process in the jam state can be quickly performed.

Note that the jam of the bill P is generally generated near the sorting means 40, but is constituted by a photo sensor or the like for detecting the passage of the bill P near the sorting means 40 and taking the operation timing of the sorting member 42. Bill detector (bill sensor)
Is provided in advance, and this bill detector is used for detection of a jam by the sorting means 40. That is, the banknote P being transported passes through the banknote detector for a predetermined time, but the banknote is clogged in the sorting means 40, and when the banknote P stays at the position of the banknote detector, the detection time of the banknote P becomes longer. Is used to determine the occurrence of a jam.

Another method is jam detection called shift control. This is to confirm that the bill P is being conveyed between two adjacent bill detectors for a predetermined time.

In this method, the paper money detector does not detect the jam at the time of dark detection, but detects that the paper money P that has passed through the preceding paper money detector does not reach the next paper money detector within a predetermined time. Judge the occurrence of jam. Therefore, the jam detection in this case is a bright detection.

The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the invention.

[Effects of the Invention] As described above, according to the present invention, the required number of concave grooves provided on the outer peripheral portion of the guide member and the protrusions of the rotating pieces arranged in a comb-like shape of the distribution member are nested. Since the structure is formed, it is possible to provide a paper sheet sorting and accumulating apparatus capable of easily performing the jam processing regardless of the conveying direction of the jammed paper sheets.
