Abstract

PURPOSE:To drop a foreign substance properly toward the underside of a stacking part and remove the foreign substance by holding paper sheets off an intake roller together with a front panel when the paper sheets are not in an intake process. CONSTITUTION:Paper sheets are thrown into a throwing zone (a) between a front panel 1 and a backup 2. In this case, a foreign substance, if mixed therein, drops into a pan 28 via a gap on a floor 7. Thereafter, the floor 7 vibrates, the paper sheets are arrayed and the foreign substance completely drops into the pan 28. Furthermore, the backup 2 and the front panel 1 move toward an intake roller 3. Then, a part of the intake roller 3 projects internally through the notch of the front panel 1 and is pressed with the paper sheets. Succeedingly, the paper sheets are taken in with the roller 3 one by one, while double intake is being prevented with a gate roller 25, According to the aforesaid constitution, the foreign substance contained in the paper sheets can be completely removed.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention is provided in an automatic teller machine, automatic teller machine, etc., and is used to sequentially collect accumulated paper sheets (banknotes) one by one. The present invention relates to a paper sheet loading device.

(Prior art) Generally, this type of paper sheet intake device includes a take-in roller that takes in the paper sheets accumulated in a stacking section, and two sheets that are arranged opposite to this take-in roller to prevent double taking of paper sheets. Remover prevention machine m (
It consists of a gate roller) and a backup roller that presses paper sheets against the take-in roller.

If there is a foreign object, such as a coin or a paper clip, among the stacked paper sheets, it may get caught in the take-in section between the take-in roller and the double-sheet prevention mechanism placed opposite it. This may result in the inability to capture paper sheets or damage to the capture device.

For this reason, methods are generally adopted in which a gap is provided in the floor that receives paper sheets in the direction of gravity to allow foreign objects to fall, and the floor is further photographed to allow foreign objects to fall through the gap. There is.

(Problems to be Solved by the Invention) However, since the double-sheet prevention mechanism is provided facing the sheet stacking section opposite to the take-in roller,
The problem remains that foreign matter tends to remain in the take-in portion between the double-sheet prevention mechanism and the take-in roller, and that the foreign matter cannot be removed sufficiently. The present invention aims to solve these problems.

[Configuration of the Invention (Means for Solving the Problems)] In order to solve these problems, the present invention includes a take-in roller that takes in paper sheets one after another, and a take-in roller that is arranged opposite to this take-in roller. A double-sheet-taking prevention mechanism for preventing paper sheets from being taken twice, a back-up for pressing the paper sheets against the take-in roller, and a front panel facing the back-up and facing the side where the take-in roller is arranged with respect to the paper sheets are provided. A front panel is supported so as to be movable toward and away from the take-in roller, and the front panel is moved away from the take-in roller when not taking in paper sheets, and moved to the side where the take-in roller is placed when taking in sheets. A part of the take-in roller is nested and protrudes inside the front panel, and this protrusion allows paper sheets to be taken in by being pressed against the take-in roller via the backup.

(Function) When not taking in paper sheets, that is, when inserting paper sheets between the front panel and the backup, the front panel is spaced from the take-in roller, so that coins and If a foreign object such as a paper clip gets mixed in, the front panel restricts the foreign object and prevents it from entering the intake area between the intake roller and the double-sheet prevention mechanism, and allows it to fall accurately below the collection area. .

The images can be taken in sequentially one by one. When the taking in is completed, a residual check is performed by the residual detection cell 51, and after that, each member returns to its initial position, and the sheet taking in process is completed. [Figure 4(d)].

Next, the operation of discharging paper sheets to the stacking section A will be explained with reference to FIGS. 1 and 5.

First, the backup drive motor 41 rotates clockwise from the state shown in FIG. 1(a) as shown in FIG. 1(C).

In response, the backup 2 and the front panel 1 move against the springs 38, 37 to the opposite side of the take-in roller 3, and in this position the movable part 4 of the backup 2
5 is driven by a solenoid (not shown) to open outward, and in this state, the front panel 1 is released via the discharge roller 27.
Paper sheets are ejected between the back-up 2 and the back-up 2 [Fig. 5(a)].

Thereafter, the movable part 45 of the backup 2 is closed by turning off the solenoid, and then the front panel 1 and the backup 2 are returned to their initial positions by the operation of the backup drive motor 41 (FIG. 5(b)).

In this state, the floor 7 is raised by the operation of the floor drive motor 11, and the shutter 1 is raised by the operation of the shutter drive motor 17.
5 is opened, thereby making it possible to return paper sheets to the customer [FIG. 5(C)].

When the paper sheet is extracted by the customer, the shutter 15 is closed by the operation of the shutter drive motor 17, and the remaining paper sheet is roughly checked by the residual detection cell 51, and the sheet discharging process is completed. Figure 5(d)].

Note that the present invention is not limited to the above-mentioned example,
Various modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As explained above, according to the present invention, when paper sheets are not being taken in, the paper sheets M are kept separated from the taking-in roller together with the front panel, so that there are no coins, clips, etc. on the paper sheets. If a foreign object gets mixed in, the front panel restricts the foreign object and prevents it from entering the intake area between the intake roller and the double-sheet prevention R mechanism. This has the effect that it can be dropped and removed below the accumulation section.
