Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a paper sheet stacking device that stacks paper sheets one after another, and in particular prevents the edges from folding when paper sheets are introduced and aligns them. This invention relates to a paper sheet stacking device that facilitates the process.

(b) Prior art At present, in machines that handle banknotes, such as automatic teller machines (ATMs) and other cash processing devices and automatic vending machines, in order to speed up cash processing, banknotes are sequentially placed on a stop plate. A banknote stacking device is used that transports banknotes and stacks them one on top of the other.

(c) Problems to be solved by the invention However, in the past, as shown in FIG. 1, the width L2 of the stop plate 2 was wider than the width L1 of the banknote 1, so the thin banknotes with low bending rigidity were tilted and the stop plate 2, the corners of the banknotes were bent when they hit the stop plate 2. When such an edge fold occurs, as shown in FIG. 2, the next introduced banknote 3 gets caught on the edge fold part 4 and overlaps with the edge folded note 1 at an angle, resulting in uneven bills. This resulted in inconveniences such as banknotes being piled up and jamming.

Further, in order to stack banknotes at high speed, the banknotes are conveyed to the stacking section at high speed. For this reason, in conventional banknote stacking devices, banknotes that hit the stacking plate bounce back, which is another cause of bill misalignment.

The purpose of this invention is to provide a paper sheet stacking device that can smoothly align and stack paper sheets while preventing the ends of the paper sheets from folding and bouncing back. There is a particular thing.

(d) Means for solving the problem This invention introduces the paper sheets from above toward the stop plate forming the bottom of the stacking section, and transports the paper sheets until the edge of the paper contacts the stop plate. In a device for stacking paper sheets in sequence along a stop plate, the stop plate has a flat part wider than the long side of the paper sheets and is continuously located on the paper sheet introduction side. , a narrow flat part formed to have a width only at the center of the edge of the paper sheet to be introduced, and a friction roller rotating in the paper sheet introduction direction on the side surface on the paper sheet introduction side. and a pressing plate that is biased toward the friction roller and retreats from the narrow side of the stop plate to the wide side as paper sheets are accumulated, and furthermore, the narrow plane portion of the stop plate is configured such that: A notch is formed at the tip of the friction roller, and a portion of the friction roller is disposed at a position where the friction roller enters the notch.

(e) Function In the paper sheet stacking device of this invention, paper sheets are introduced toward the stop plate. Paper sheets are stopped and accumulated when they hit the stop plate, but since the stop plate is narrow enough to contact only the center of the edges of the paper sheets, the corners of the paper sheets are stopped and accumulated by the stop plate. It does not hit the edges and does not cause edge breakage. Also, when stacking paper sheets, they are stably supported by the wide part of the stop plate. In addition, in high-speed processing equipment, paper sheets are conveyed at high speed, but since the friction rollers that the paper contacts come into contact with rotate toward the stop plate, there is no bounce, and the paper sheets do not come into contact with the stop plate. sorted by state. Furthermore, since the friction roller is positioned downward, the paper sheets are fed at the lower end side, and the paper sheets are immediately aligned.

As a result, the paper sheets can be stacked in a straight line without folding.

(f) Example Figure 3 is a side view of the bill stacking section of an ATM implementing this invention, Figure 4 is a sectional view taken along the line E-E in Figure 3, and Figure 5 is a cross-sectional view taken along the line F-F in Figure 3. It is an arrow sectional view.

The stop plate 10 has a flat part (wide part) wider than the length of the long side of the banknote, and a flat part 1 narrower than the length of the long side.
1 (narrow width part) and are arranged horizontally. The narrow plane part 11 is located on the banknote introduction side, and as will be described later, the banknotes are introduced so that their edges come into contact with the upper surface of the plane part 11, and are sequentially introduced to the plane part wider than the plane part 11. They are piled up and accumulated. The stop plate that stops the banknotes in this way is constituted by the upper surface of the stop plate 10 made up of the two flat parts.

In order to convey banknotes to the stop plate 10, a conveyance device composed of rollers is arranged on the plane portion 11 side. That is, above the flat part 11 located on the banknote introduction side, a feed roller 12 and a restraining roller 15 biased by a lever 13 and a spring 14 in a direction opposite to the feed roller 12 are arranged. Further, below these rollers, friction rollers 16 and 17 whose surfaces are made of rubber or the like and have a friction coefficient larger than that of banknotes are arranged in two stages, and the rotation axis of the lower friction roller 17 is closer to the stop plate 10. It is located above. As shown in Figures 4 and 5,
Each of the friction rollers 16 and 17 is composed of a pair of rollers, and the friction roller 17 is disposed at a position where a portion of the friction roller 17 enters a notch portion on the tip side of the flat portion 11. While the bill is being held between the feed roller 12 and the press roller 15, the banknote is fed into the flat section 11 with its short side being the traveling direction, and the edges of the banknote are placed on the top surface of the flat section 11 by friction rollers 16 and 17. are transported until they come into contact with each other. A pressing plate 18 is provided on the upper side of the stop plate 10, to which wheels are attached so as to slide along the upper surface thereof, and which is biased toward the friction rollers 16 and 17 by a spring 19.

In the conveyance device configured as described above, when a banknote is introduced toward the flat part 11 by the feed roller 12 and the press roller 15, the friction roller 16,
17 acts on the bill to draw it downward, and the bill reaches the stop plate 10. The first banknote descends along the pressing surface of the pressing plate 18, and the second and subsequent banknotes descend along the paper surface of the banknotes that have already arrived. When introducing this banknote, the pressing plate 1
Due to the action of pressing the bill against the friction rollers 16 and 17 at 8 and the action of pulling the bill into the friction rollers 16 and 17, the upper end of the bill does not fall to the side opposite to the pressing plate 18 and is always kept straight. Stop the banknotes with plate 1
It can be placed on 0. Moreover, after the banknote stops on the flat surface 11, the friction rollers 16, 17 and the banknote slip, and the conveying force is no longer transmitted, so that the banknote can be maintained in an upright state. By repeating banknote conveyance in this manner, banknotes can be accumulated one after another on the pressing plate 18 side.

In the above-mentioned banknote stacking section, as described above, the width of the stop plate 10 on the banknote introduction side is narrowed to prevent the ends of banknotes from folding. That is, as shown in FIG. 5, the width B of the flat part 11 is narrower than the width A of the banknote (B<A), and the banknote 21 is introduced at an angle with respect to the flat part 11 as shown in FIG. At this time, the corners of the banknote do not come into contact with the flat part 11, and no edge folding occurs. After a part of the edge of the banknote 21 comes into contact with the flat part 11,
Since the bill rotates under the conveyance force of the friction rollers 16 and 17, the bill is stopped on the flat surface 11 in the correct direction as shown by the two-dot chain line. By making the width of the flat portion 11 narrower than the width of the banknote in this way, it is possible to prevent the ends of the banknote from folding, and the friction rollers 16 and 17
By providing this, it is possible to prevent banknotes from bouncing back. This allows banknotes to be stacked continuously without causing irregularities or jamming. Also,
Since the position of the friction roller is low, it is possible to feed the banknotes at a portion close to the non-end side, and the banknotes can be immediately aligned.

Next, an example in which the present invention is implemented in a banknote stacking section of an ATM, a vending machine, etc. that requires a so-called escrow function, in which banknotes stacked in the stacking section are ejected from the stacking section again, is shown in FIGS. 7 and 7. This will be explained with reference to FIG. FIG. 8 is a sectional view taken along the line GG in FIG. 7. In these figures, the same parts as those in the above embodiment are given the same numbers.

The difference between this example and the previous embodiment is that a portion corresponding to the plane portion 11 of the stop plate 10 is constructed with a gate 31 supported so as to be openable and closable. When the gate 31 is closed, the top surface of the tip of the gate 31 forms the same horizontal plane as the horizontally fixed stop plate 30, thereby forming a stop plate for stopping the banknotes. With the gate 31 closed, bills are introduced and the gate 31 is closed.
When the gate 31 is opened downward after stopping the bill on the top surface of the tip, the gate tip is separated from the stop plate 31 and the bill can be guided downward. By supporting the gate 31 in such a manner that it can be opened and closed, a banknote stacking section having an escrow function can be constructed, and the width C of the upper surface of the tip of the gate is formed to be narrower than the width A of the banknotes, as shown in FIG. Therefore, as in the embodiment described above, it is possible to prevent the edges of the banknotes from folding when the banknotes are introduced, and to smoothly stack the banknotes continuously. Further, the action of the friction rollers 16, 17 and the position of the friction roller 17 can prevent the banknotes from bouncing back or becoming loose.

Note that the above example is applied to an ATM that handles banknotes, but it can be applied to any paper handling equipment as long as it is a piece of paper with low rigidity where the corners hit the stop plate and cause the ends to fold. The present invention can also be applied to.

(g) Effects of the invention As described above, according to the paper sheet stacking device of this invention, the width of the stop plate is formed only at the center of the edge of the paper sheets, so that the paper sheets are not tilted. Even if the paper sheet is introduced into the paper sheet, its corner will not come into contact with the stop plate, and folding of the paper sheet can be reliably prevented. In addition, when stacking, the wide part of the stop plate is used, so the paper sheets can be supported stably. Further, by providing a friction roller in the introduction section, even if paper sheets introduced at high speed hit the stop plate, they will not bounce back. Furthermore, because the friction roller is located low, the paper sheets are fed near the leading edge (lower edge side), and as a result, the paper sheets are quickly aligned to prevent them from turning up at the lower edge. can be done. In this way, it is possible to eliminate disturbances in the stacking of paper sheets due to folded edges, bounce, turn-up, etc., and it is possible to correctly align and stack paper sheets even in a high-speed processing device for paper sheets.
