Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet dispensing device such as that built in an automatic teller machine used in banking, for example.

Among the paper industry for banknotes, slips, and cards, the wire handling device i for handling M (banknotes) such as the above-mentioned example has conventionally been used to feed out banknotes by contacting the banknotes with the banknote opening surface of the banknote storage section. Bills were fed out one by one from the bill storage section using a loaf and a friction loaf that pressed against the feeding lobe and restricted the number of bills from coming out.

However, such a feeding mechanism requires friction lobes, which complicates the structure, and these friction lobes constantly apply a constant suppressing load to the feeding roller, accelerating wear of the feeding lobe and shortening its service life. This was the cause of the decline.

Furthermore, if the contact pressure between these two rollers is not equal,
When the banknotes are fed out, the banknotes tend to swing sideways and cause problems in the subsequent conveyance path, so the contact pressure between these two rollers must always be maintained at a constant level, which is a frequent drawback.

Therefore, the purpose of this paper sheet feeder 1 is to provide a paper sheet feeding device that can feed one sheet without requiring a friction loaf.

According to the present invention, since the semi-moon-shaped roller provided to feed out the banknotes is provided with both low weight and 1': kg members around the circumferential surface, this semi-moon-shaped lobe is used to feed the paper sheets. If it is placed opposite to the opening surface of the paper sheet storage section, based on the rotation of this half-moon-shaped loaf, it will rotate while slipping in constant pressure contact with the paper sheets in the low friction coefficient part in the front half of the rotation direction. , rotates while holding paper sheets. Then, in the latter half of the rotation direction, where the friction coefficient is still high, the rotor rotates in a state of high frictional contact with the paper sheet, so it rotates as if turning over the paper sheet one by one.

In addition, a sheet of paper turned over based on the rotation of the semi-moon-shaped roller has a gap formed by the rotational position of the semi-circular notch of the semi-moon-shaped loaf, and the paper sheet is turned over in a curved shape. The 9 sheets that are turned over return to this empty 1 (0 copy) and expand to their normal state.

Furthermore, since the half-moon-shaped loaf is equipped with a conveyor roller,
A single sheet of paper is nipped and conveyed between this conveyance lobe and a downstream conveyance table (V) that faces the conveyance lobe, and can be fed out and conveyed thinly.

In addition, if you store paper sheets in a curved manner so that they face the feeding opening of the paper storage section, it will be easier to separate new paper sheets with a high degree of adhesion, and it will also be possible to The multiple operations of flipping each sheet of paper based on this can be made more reliable.

An embodiment of the present invention having such characteristics will be described below with reference to Figure i'lj-+.

The drawing shows a bill dispensing device h used in an automatic teller machine, and as shown in FIGS. Side 3
It is composed of a half-moon-shaped roller 4 which is disposed opposite to the banknotes 1 and feeds out the banknotes one by one, and a conveyor belt 5 which feeds out and conveys the banknotes 1.

The above-mentioned banknote storage section 2 consists of a stacking frame 6 for storing banknotes l and a weight 7 for pressing down the banknotes l upwardly inside the stacking frame 6.
The stacking frame 6 is formed with an open top surface, and banknotes l are loaded through this top surface. The lower surface of the stacking frame 6 is inclined downward from the longitudinal center of the stacking frame 6 to form a long inclined plate 8 and a short inclined plate 9. The banknote l is fed out through this feeding opening i'111B.

A notch is formed in the short inclined plate 9, and the circumferential surface of a half-moon loaf, which will be described later, faces this part and comes into contact with it in order to feed out the banknotes l in the stacking frame 6. Still, the width and length of the frame 60 in the collection A'1 are formed to be slightly shorter than the short side length of the banknotes 1, so that the short side of the banknotes is curved in the gap when the banknotes 1 are stacked in the stacking frame 6. There is.

This is to ensure the feeding operation of banknotes l,
The curved state of both inclined plates 8 located at the bottom of the stacking frame 6.
The banknote L is stored along the bank 9 in a curved state with the central part of the short side facing F.

Further, a weight 7 is placed on the upper surface of the banknotes l stacked in the stacking frame 6 to stack all the banknotes in the stacking frame 6 into a uniformly curved state. For this reason, the weight 7 is provided so as to protrude downward in the same curved shape commensurate with the curved state of the lower banknote.

The above-mentioned half-moon roller 4 has a low-friction member lO having a low friction coefficient such as Teflon on its curved surface, and a high-friction member 11 having a high-friction coefficient of rubber 4 on its circumferential surface, and conveys the banknote through it. The stomach friction member 11 is formed in the rear half of the half-moon-shaped loaf 4 in the rotational direction, and the transportation roller 121 is formed in the first half of the half-moon-shaped roller 40 in the rotational direction. The half-moon loaf 4 provided in this manner is connected to the left and right pair by a drive shaft 18, and a pulley 14 and a cam 15 are pivotally attached to the end of this drive shaft 1B.
Rotation from the feeding motor 17 via the drive shaft 18
is transmitted to. In addition, in order to detect one revolution of this jlfJ axis 1B by the rotation of the cam 15, the micro switch 1 is
8 is provided. And these half-moon loaf 4,4
The upper end of the stacking frame 6 is disposed opposite to the notch of the short inclined plate 9 located at the delivery opening surface 8 of the above-mentioned stacking frame 6.

The above-mentioned conveyor belt 5 has two pulleys 19, one end of which is disposed opposite to the feed-out opening tm8 of the stacking frame 6, and the other end of which is disposed facing the banknote feed-out conveyance direction (the same inclination direction as the long inclined plate 9). 2
A flat plate μ)21 is stretched between 0 and this flat plate)V)2
In order to drive the pulley 19 on one side, drive #r A /
A conveyance motor 2B is provided through the banknote 22, and the banknote bell (21) is rotated in the banknote payout direction 17 by driving this motor 28.

Furthermore, a corresponding loaf 24 is provided on the inside of the belt at the same portion in the middle of this flat plate A/) 21, and this corresponding lobe 24 has a central portion of a loaf support plate 26 pivotally attached to a horizontally installed fulcrum pin 25. The tip of this roller support plate 26 corresponds to the roller 24.
is supported, and the corresponding roller 24 is always urged toward the inner side of the child belt 21 and toward the conveyance surface by the tension of a spring 28 provided at the base end.

As a result, the conveyor belt surface of the flat bell 21 is sandwiched and corresponds to the above-mentioned conveyor roller 12, thereby enabling the clamping and conveyance of banknotes.

Reference numeral 28 denotes a fixed loaf, which is provided at a position corresponding to the pulley 20 on the other side, and is used to securely clamp and convey banknotes at this portion in the same way as the above-mentioned two p-ws 12 and 24. , it is determined whether or not the bill fed out onto this flat belt 21 has passed.

80 is a banknote guide plate, and 31 is a stopper.

The above-mentioned conveyance belt 5 is provided in a pair on the left and right, and further includes the above-mentioned accumulation frame 6, the drive shaft 1B of the half-moon roller 4, the motor for manual use 17, the conveyance motor 28 of the conveyance belt 5, each pulley 19. 20.28, the fulcrum bin 25, and the stopper 81 are each supported by a frame (not shown).

As shown in FIG. 1, in the sheet stacking device configured as described above, in its standby position, the conveyance loaf 12 is stopped at a rotational position facing the corresponding roller 24, and the semicircular loaf 4 is rotated. The upper part, the low-friction Tsukai lO, is the accumulation frame 6.
The green opening surface 8 of the paper is in contact with the banknote l.

Then, if there is a request to dispense banknotes, a discharge command signal 1;
Based on this, the conveyance motor 28 is started, and then the feeding motor 17 is started, and based on this, the half-moon-shaped loaf 4 begins to rotate in the feeding direction (clockwise rotation), and while the half-moon-shaped roller 4 is rotating, The microswitch 18 is turned OFF, and the low friction member 10 rotates while slipping against the bill l, so the banknote is not dispensed, but the high friction member 11
In the 0 part, due to the high frictional contact that occurs with the banknote l,
The banknotes are flipped over one by one as shown in Figure 8.

At this time, the banknotes 1 are forced upwardly and downwardly by the weight 7, so the banknotes are in #1#'f, constant-pressure contact state, and the frictional resistance is greater than that of the high-friction member. The contact resistance of 11 ensures that one sheet can be turned over.

Then, as shown in FIG. 4, the banknote I is flipped from the curved state to the extended state. At this time, since the half-moon loaf 4 is provided with a half-moon-shaped gap, the bill effectively utilizes the gap and easily changes from a curved state to a normal extended state.

Then, as shown in FIG. 5, when the semicircular loaf 4 rotates and the conveying loaf 12 faces the corresponding loaf 24 at one rotation position, the cam 15 contacts the microswitch 18 to give an ON signal, and the feeding motor 17 The rotation of the banknote 1 is stopped, and the ejected banknote l is held between the flat plate μ) 21 and the conveyance loaf 12, pulled out through the stacking frame 6, and transferred to the subsequent conveyance means (
(not shown).

When the sensor 29 detects the rear end of the banknote being conveyed, the rotation of the conveyance motor 28 is stopped after a predetermined period of time after the green banknote has been completely removed, and the operation of feeding out one banknote is completed.

By continuously performing such a feeding operation, the requested number of banknotes is fed.

In the above-described embodiment, a vertical stacking frame is shown, but the present invention is not limited to this, and a horizontal stacking frame may be provided so that banknotes are biased into a curved state by a horizontal bending panel or the like.
