Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a paper sheet arranging device for arranging the front and back sides of paper sheets, such as a banknote deposit/dispensing machine or a banknote sorting machine.

[Prior art]

In a conventional paper sheet sorting device, paper sheets in a mixed state are sorted into two conveyance paths by a sorting device that operates based on the front and back discrimination results of a discrimination section installed in the middle of the conveyance path. In one conveyance path, the paper sheets are conveyed as they are, and in the other conveyance path, the paper sheets are reversed by a reversing device disposed on the way, and then merged with the one conveyance path. A mechanism for aligning the front and back sides of paper sheets is known (Japanese Unexamined Patent Application Publication No. 75392/1983, etc.).

Furthermore, Japanese Patent Application Laid-Open No. 55-91258 proposes a device for reading both sides of a document in a reading device for a copying machine, a facsimile transmitter, etc.

This reading device is configured to send the original that has passed through the original reading unit to either the first paper ejection unit or the paper ejection unit shown in FIG. When sending the paper to the document ejection section, either swing the movable guide plate provided between the second paper ejection section and the document reading section to prevent it from returning to the document reading section, or move the transport rollers. The configuration was such that the edge of the document was forcibly fed toward the second paper discharge section by a drive roller or the like for switching the rotation direction.

[Problem that the invention attempts to solve]

In the conventional front-back sorting device, the front paper sheets and the back paper sheets are sorted and passed through separate conveyance paths, but since one conveyance path is provided with a reversing mechanism, each It is difficult to accurately control the time required for the two processes from merging through the conveyance path to sorting. Therefore, it is difficult to ensure a constant conveyance interval and a constant conveyance order of paper sheets, and continuous and smooth processing cannot be ensured. Furthermore, the reversing device reduces the processing speed, and the configuration of two conveyance paths, a sorting mechanism, a reversing mechanism, etc. makes the entire device complicated and large.

In addition, in the latter reading device such as a copying machine or facsimile transmitter, the original comes into contact with the lower part of the movable guide plate when it is sent to the second paper ejection section, so the copying process cannot be performed as in a copying machine or facsimile transmitter. This is fine when the feeding speed is slow, such as when performing transmission processing, but when paper currency is reversed or non-reversed at high speed to align the front and back sides, it can cause jamming, which poses a problem in terms of speeding up. Furthermore, a mechanism for swinging the movable guide plate or a mechanism for controlling the drive roller is required, resulting in a problem that the mechanism becomes complicated.

This invention solves the above-mentioned conventional drawbacks and ensures a constant conveyance interval and conveyance order of paper sheets to ensure continuous,
In addition, it is intended to enable smooth processing, and to realize faster processing, simpler equipment, and smaller size.

[Means to solve the problem]

This invention uses a paper sheet sorting device in which paper sheets whose front and back sides have been identified are conveyed one after another at a predetermined interval in a mixed state, and the paper sheets are conveyed with their front and back directions aligned. a linear strip-shaped reversible conveyance path that is sandwiched between a pair of conveyance belts and conveys the material so as to move forward and backward; a conveyance exit path that continues in a straight line with respect to the conveyance surface of the reversible conveyance path at one end side of the reversible conveyance path; Continuous to the other end of the reversible conveyance path, and approximately U
a return conveyance path that is folded back in a letter shape and merges with the conveyance exit path; and a conveyance entrance path that introduces paper sheets from one end side of the reversible conveyance path at a predetermined angle with respect to the conveyance surface of the reversible conveyance path. It is characterized by:

[Effect]

According to the device for arranging both front and back sides of this invention, paper sheets in a mixed state are conveyed from the conveyance entry path to the reversible conveyance path at predetermined intervals, and the sheets are sandwiched between the conveyor belts in the reversible conveyance path. to hold the paper sheet in its original flat state. If the paper sheet is determined to be the back side, for example, it is fed out in a straight line from one end of the reversible conveyance path to the conveyance exit path. In this case, in the reversible conveyance path, the paper sheets are held flat by the conveyance belt, and the conveyance exit path is connected in a straight line to the conveyance surface, so the sheets can be conveyed simply by reversing the conveyance belt. Paper sheets can be handed over on the way out. On the other hand, if the paper sheet is determined to be front side, the paper sheet is sent from the other end of the reversible conveyance path to the return conveyance path, and is made to turn in this return conveyance path.
It is made to join the conveyance exit path in an upside-down state. That is, by simply changing the driving direction of the reversible conveyance path, paper sheets can be smoothly conveyed to either the conveyance exit path or the return conveyance path, and the front and back sides can be aligned by selecting the conveyance path.
