Description

[Detailed Description of the Invention] A. Industrial Field of Application The present invention provides a banknote supply device, device, and body that accurately and reliably feeds the exact number of banknotes specified by the user, regardless of whether the banknotes are new or old in use. Concerning automated cash dispensers that dispense with sex.

B. Prior Art Automated teller machine owners and users want brand new cash to be dispensed from the dispenser. The banknote holding cassette has approximately 30% more storage space than old banknotes, which tend to swell when stacked.
Since a moderate amount of new banknotes can be inserted, the cost of replenishing banknotes will be lower if new banknotes are supplied. Customers also prefer to receive new bills that can be used rather than crumpled and dirty old bills.

Additionally, old banknotes are sometimes taped or stapled to their owners, but such banknotes must be removed in order to be reliably dispensed with commonly known payment machines. There must be. Such operations increase the cost of using old banknotes in cash dispensers.

However, in order to provide uninterrupted service when new bills are not available, a cash dispensing machine that can dispense not only new bills but also old bills is desired.

Many different devices for feeding banknotes are known in the art.

U.S. Pat. No. 4,221,376 discloses a type of device that has been proven to accurately and reliably dispense new bills. The device disclosed in U.S. Pat. No. 4,459,052 provides a more accurate and reliable supply of old banknotes.

However, devices of the type disclosed in U.S. Pat. No. 4,459,052 are unable to reliably separate and accurately dispense stacks of new banknotes that have become clumped together due to, for example, humidity and temperature.

The present invention therefore represents a new modification to a device of the type disclosed in U.S. Pat. No. 4,459,052.

Improve the ability to accurately and reliably dispense new notes.

Other attempts have failed to provide such capabilities. These efforts downplay the inability to accurately deliver new notes and emphasize the ability to supply old notes. If new notes have to be supplied, another means is for the owner to send them through a known type of note counter in a bank or other financial institution, whereby the new notes are transferred to the old banknotes under controlled conditions. A method of turning it into a tag has been proposed. Having to swipe new bills through the counter several times significantly increases operating costs, as does having to remove tape or staples from old bills.

Problems to be Solved by the C0 Invention It is an object of the present invention to provide a single device capable of accurately and reliably dispensing both old and new banknotes.

Means for Solving the D0 Problem The present invention overcomes the problems of the type disclosed in U.S. Pat. Solve the problem of supplying new bills for the device.

The gradient member applies pressure inwardly to each of the bills as the bills are raised toward the friction feeder.

Bend the banknote upwards to separate it from the banknote below.

After bending upward and separating from the notes below, each note passes over the top of the slope member and flattens out again, becoming part of a loose small stack of separated notes. The banknotes in this stack are reliably and accurately dispensed by a friction feeding device which has proven to be sufficiently effective for dispensing old notes.

In a preferred embodiment of the invention, the banknote block separation gradient member means is formed by two gradient members, which compress and bend the banknotes twice inwardly, such that the position of the banknotes in the stack above the gradient members is above and below. Two or more banknotes are reattached to each other after being shifted horizontally from the position of adjacent banknotes,
- Preventing people from being sent together.

E. Embodiment Referring to FIG. 1, a side view of one embodiment of the present invention is shown. A stack 11 of banknotes is present in the cassette 13. The cassette 13 has a movable floor or support 15, which is raised by a motor 17 via a lifting mechanism 19.
It looks like it's going down. The lifting mechanism 19 may consist of a lead screw, connecting rod and crank, or similar mechanism.

The cassette 13 has a rectangular horizontal cross section that is wider than the length and width of the banknote. Opposing side walls of the cassette are shown. Each side wall has a slope member 21.2 near the top of the cassette.
3 is installed. 5 to 1 from the top of the cassette
It has been found that if the top of each gradient member 21.23 is positioned 5 ngn below, a stack of bills separated into two pieces can be formed on the gradient member 21.23. This stack is small and loose enough to prevent re-blocking in humid, high temperature conditions, but large enough to be reliably dispensed without becoming trapped at the top of the gradient member 23. The gradient member 21.23 has an inwardly sloped flat lower surface and an arcuately sloped upper surface, peaking at the junction of the two surfaces. This arcuate top surface allows the stack of bills to be pushed down into the interior of the cassette, leaving the cassette ready for removal from the cash dispenser. Although the gradient member may be of any width, it has been found that a width of approximately 13+In provides good separation without excessive deformation of the banknote.

Feeding is effected by belt 25 across pulleys 27, 29 and 31. Rollers 33, 35 and 37 are also belt 25
The banknotes are conveyed from the stack 11 to an issue storage area (not shown). The issuance and storage area is where banknotes are stored until the appropriate number of banknotes is sent. Rollers 39 and 41 also constitute a feeding mechanism, transferring banknotes from adjacent stacks of banknotes, possibly of different denominations, to roll 2.
It was sent during 9.37 and is being transported to the issue storage area.

The stack of banknotes 11 is normally attached to the bell 1 by an actuator arm 43 that pushes down the banknotes away from the belt 25.
The distance is -25. When it is time to send a note, the actuator arm 43 is raised by the electromagnet 43 and the top note of the stack 11 of notes comes into contact with the belt 25 and is drawn by friction between the pulley 29 and the roll 47. . Since pulley 29 and roll 47 are both rotating counterclockwise, roll 47 tends to inhibit the lower, but separate, bill from being fed. Since a large number of banknotes are delivered from the top of the stack 11, the belt 25
eventually ceases to be in contact with the top of stack 11, and even though belt 25 is rotating and actuator arm 43 is retracting, no bill is advanced and therefore is not sensed by detector 49.

If the scheduled time has passed and the belt 25 is rotating but not feeding bills, the control computer energizes the motor 17 to drive the lifting mechanism 19 to move the support 15 of the cassette 13 rise. As soon as the banknote is sent, the motor 17 is turned off. Even if more than one bill is sent at the same time, multiple bills are diverted to a reject bin (not shown) and are not issued to the user. If multiple banknotes were to be issued several times, the computer would turn on the motor 17 again, but this time drive the leadscrew 19 in the opposite direction to reduce the pressure that was being applied to the stack of banknotes. lower. This is because excess banknotes were being passed through the separation gradient member.

FIG. 2 shows a preferred embodiment including the same motor 17, lead screw 19, feed wheel 31, belt 25 and actuator 43. However, in this embodiment, the bill is pushed from both ends in a direction transverse to the feed direction, causing it to arch upwardly and separate.

In FIG. 2, the banknote separating slope member is a replaceable banknote width guide 5.
It is integrated with 9 and 61. These width guides 59 and 61 are available in different sizes to accommodate longer or shorter banknotes such as those found in currencies of different countries. In addition to gradient members 51 and 53, there are gradient members 55 and 57 in series, with gradient members 51 and 53
The banknotes are bent twice as they are pushed up through the cassette 1. Furthermore, the sloped members 51.55 molded into guide 59 are made slightly lower than the corresponding sloped members 53.57 molded into guide 61, so that the banknotes will not move from one side to the other as they are pushed up through the cassette. Move 8 is coming. This lateral movement causes the banknotes to shift horizontally in the loose stack formed at the top of the cassette, reducing the probability that they will become blocks again at high temperatures and humidity.

Although the ramp members 51 and 53 have been described as integral parts of the guide, it is also possible to attach them directly to the side walls of the cassette. Similarly, in place of the belt 25 and actuator arm 43, other equivalent friction feeders include a gradient member near the feed point for separating blocks of a stack of banknotes being raised towards the friction feeder. can be used.

F6 Effects of the Invention In accordance with the present invention, a single device is provided that can accurately and reliably dispense both old and new banknotes.
