Abstract

PURPOSE:To prevent the jam due to the floating-up which is generated by the bending of a paper sheet by forming a blowing means in the vicinity of a paper sheet taking-in port of an accumulating box and pressing and arranging the paper sheets into the accumulating box. CONSTITUTION:Blowing ports 9 and 12 are formed in the vicinity of a taking-in port for the paper sheets discharged from the vane wheel 4a of an accumulating box 7. Even if a bent part exists on the paper sheet 1 accumulated in the accumulating box 7, the paper sheets can be accumulated in parallel to the accumulating surface by the wind pressure supplied from the blowing ports. The wind pressure is discharged from an air vent hole 3 formed on the accumulating box 7. Therefore, the floating-up due to the bending of the paper sheet 1 is prevented, and generation of jam is prevented, and stable accumulation operation is permitted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a paper sheet stacking device, and is particularly used in an automatic teller machine. Paper sheets that are sequentially fed out from the conveyance path are
The present invention relates to a device that holds the paper sheets by a rotating impeller and guides and stacks the paper sheets one by one into a stacking whistle as the impeller rotates.

[Conventional technology]

As a paper sheet stacking device having the above-mentioned configuration, for example, the device disclosed in Japanese Patent Application Laid-Open No. 57-27857 has been known.

As shown in FIG. 3 as a side view, and as shown in FIG. 4 as a front view (view taken along arrow B-B in FIG. 3), this device can handle three pairs of paper sheets arranged in upper and lower pairs. It is composed of conveyor belts 2a, 2b (hereinafter simply referred to as "conveyor belts"), impellers 4a, 4b, and a collection box 7. In addition, 5 is the impeller 4
The axes a and 4b are shown.

The outline of the operation of this device is as follows.

The paper sheet 1, which has been conveyed while being held between the conveyor belts 2a and 2b, is fed into the upper part of the impellers 4a and 4b. direction). A plurality of thinly wound notches 6 are formed in the impellers 4a and 4b, and the paper sheets 1 conveyed by the conveyor belts 2a and 2b are sequentially fed into each of the notches 6.

Further, a stopper 8 is provided below between the impellers 4a and 4b and at the upper edge of the accumulation box 7.
ejects the paper sheets held in the notch 6,
It is configured so that it is dropped into a collection box by its own weight and is collected.

Note that the paper sheets 1 sent out from the conveyor belts 2a and 2b
is stably fed into the impellers 4a and 4b.
The speeds of the conveyor belts 2a, 2b and the rotational speeds of the impellers 4a, 4b are configured to be synchronized.

[Problem that the invention seeks to solve]

However, in the above device, no consideration is given to a means for holding the paper sheets 1 that are sequentially stacked in the stacking box 7 parallel to the stacking surface (bottom surface), and the paper sheets 1 have a strong tendency to bend. When paper sheets 1 are successively taken into the collection box 7, there is a raised part due to the bending of the paper sheet l taken in first, and a folded part of the paper sheet 1 taken in next. Since the sheets collide with each other and the paper sheets are sequentially fed in this state, a jam may occur at that location.

The present invention has been made in view of the above circumstances, and its purpose is to solve the above-mentioned problems in conventional paper sheet stacking devices, and to reliably handle paper sheets that have a tendency to bend. It is an object of the present invention to provide a paper sheet stacking device which can take in and stack paper sheets and whose stacking operation is highly stable.

[Means for solving problems]

The above-mentioned object of the present invention is to have a plurality of blade-like holding parts capable of holding paper sheets, and to sequentially receive paper sheets sequentially conveyed through a conveyance path in the previous stage, and to hold the received paper sheets. In a paper sheet stacking device having an impeller that can rotate once to sequentially stack paper sheets into a stacking box as it rotates, a blowing means for arranging paper sheets near a paper sheet intake port of the stacking box. This is achieved by a paper sheet stacking device characterized by being provided with.

[Effect]

In the present invention, even when strongly bent paper sheets are continuously taken into the collection box by the wind pressure blown from the air outlet provided near the paper sheet intake port of the collection box, The paper sheets taken in first are pressed against the stacking surface in the stacking box to eliminate lifting caused by folding.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a side view of a paper sheet stacking device showing one embodiment of the present invention, and FIG. 2 is a view taken along the line A--A.

In both figures, symbols 1, 2a, 2b, 4a, 4b, 5-
Reference numeral 8 designates the same component as previously shown in FIGS. 3 to 5, 3 is an air vent hole provided in the collection box 7, 9.12 is an air outlet to be described later, and 10.11 is not shown in the figure. The air duct is connected to an air source that is not connected to the air source.

In this embodiment, the conventional paper sheet stacking device is provided with air outlets 9 and 12 for blowing air into the stacking box 7 through the air pipes 10 and 11. Even if the paper sheets 1 stacked in the stacking box 7 are bent due to the wind pressure, they are stacked parallel to the stacking surface.

Although the details of the air outlet 9 are not shown in FIG. 2, it is constructed in the same way as the air outlet 12.

According to this embodiment, even when paper sheets 1 that have a tendency to bend can be continuously stacked, they can be reliably captured and stacked.

In the above embodiment, the ventilation ports 9 and 12 are replaced by the ventilation pipe 10.
．． Although an example has been shown in which the air outlets 9 and 12 are configured in a nozzle shape attached to the air outlet 11, it goes without saying that the air outlets 9 and 12 may have a structure other than this. Further, the arrangement may be changed in various ways within the range that does not interfere with the operation of other components.

〔Effect of the invention〕

As described above, according to the present invention, there is provided a plurality of wing-shaped holding parts capable of holding paper sheets, and the paper sheets sequentially conveyed through the conveyance path in the previous stage are sequentially received. In a paper sheet stacking device having a rotatable impeller that sequentially stacks paper sheets in a stacking box as it rotates, the paper sheets are arranged in the vicinity of a paper sheet intake port of the stacking box. Since the paper sheet stacking device is equipped with an air blowing means, even paper sheets with a tendency to bend can be reliably taken in and stacked. It is something to play.
