Abstract

PURPOSE:To make it possible to precisely detect a conveying condition by detecting and counting bundles of sheets conveyed by a conveying means so that data of a full number are delivered when the counter number exceeds a regulated number while data of a full stay are delivered when the detected time exceeds a regulated time. CONSTITUTION:Sheets P0 such as bundled banknotes or the like, are fed by a conveying means 2 in a sheet stacking device 1, and are charged into a storage means 4 after a detecting lever 3a of a detecting means 3 is actuated. Detection signals from the detecting means 3 are counted by a number data output means 5 through a CPU 10, and when thus counted number exceeds a regulated number, the CPU 10 allows an recognition control means 9 to deliver data of a full number (warning). The time of output of the detection signals from the detecting means 3 is counted by a staying data output means 6, and when thus counted time exceeds a regulated time, the recognition control means 9 delivers data of a full stay. Further, the drive of the conveying means 2 is stopped simultaneously with the delivery of the data of a full number and the data of a full stay. Thus, a full condition of the storage means is precisely detected, thereby it is possible to prevent occurrence of an abnormal condition.

The discrimination unit 35 discriminates whether the incoming banknote P is of type 2, front or back, whether it is torn, whether it is taped or not.

In addition, on the front of the discriminator 31, there is a bill type designation button that allows the operator to seal each type of bill P (10,000 yen, 50,000 yen, 1,000 yen, etc.) by a certain number (for example, 100 pieces). (not shown) is provided.

Then, the bill P of the bill type specified by the bill type designation button is
are conveyed to the sealing machine 32 along the conveyance path 36, and banknotes P of a bill type not specified by the note type designation button are conveyed to the conveyance path 37.
and then to the upper accumulation section 38a.

38b and 38G, respectively.

On the other hand, the sealing machine 32 is provided with a front and back stacking section 39 arranged with an opening facing the conveyance path 36, and this front and back stacking section 39 aligns the front and back sides of the banknotes P. There is.

Then, the banknotes P whose front and back sides are aligned are sent to the rear band sealing unit 41 where they are separated by a separator 40 into designated number of sheets, and are bundled by the band to form a banknote Po, which is a paper sheet which is an embodiment of the present invention. It is designed to be supplied to the integration device 1.

Here, the paper sheet stacking device 1 will be explained with reference to FIGS. 1 to 3.

This paper sheet stacking device 1 is arranged facing a conveyance means 2 for conveying a bundle Po, which is a bundle of sealed paper sheets P, in the direction of arrow X, and a conveyance path for the bundles Pa in this conveyance means 2. For example, a detection means 3 such as a limit switch, a storage means 4 such as a storage box having an upward opening disposed below the discharge end of the conveyance means 2, and a detection lever 3a of the detection means 2 are held in a grip P.
