[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet feeding device used in a bill dispensing device and the like, and in particular, sheets (paper sheets, films, thin plates, etc.) are separated from the bottom of the accumulating and accommodating section, one by one. The present invention relates to a sheet feeding device for feeding.

[0002]

2. Description of the Related Art As shown in FIG. 8, a conventional banknote payout device includes a box-shaped storage section 2 for accumulating and storing a large number of banknotes 1 and a banknote deposit provided on the storage section 2. A load applying mechanism 10 for applying a load to the paper, and a roller peripheral surface is projected into the bill surface exposure hole 8 opened on the bottom surface of the storage portion 2,
A banknote kicking roller 3 as a separating means for contacting a friction material 3a such as rubber attached to a part of the peripheral surface with the bottom surface of the banknote deposit to laterally shift the banknote from the bottom discharge port 2a and discharging the banknote. The roller 3 and the transmission belt 3b rotate in synchronism with each other, and the lower pressure contact drive roller (feed roller) 4 on which a friction material 4a such as rubber is attached to a part of the roller peripheral surface and the upper side formed of sponge or the like. Pressureless non-rotating roller (friction roller)
5, the press-contact winding area 6 between them receives the leading edge of the banknote that is ejected and blocks the entrance of the accompanying banknote, and the friction material 4a makes contact with the banknote to roll the banknote one by one to the outside. And a pressure contact type double feed prevention device 7 for feeding.

The load applying mechanism 10 includes a bill holder 10a, a torsion spring 10b, and links 10c and 10d.
It is a pantograph mechanism using the, and is an expansion and contraction mechanism that elastically biases the banknote holder 10a downward.

The bottommost banknote of the banknote stack is discharged laterally by the contact of the friction material 3 of the banknote kicking roller 3,
Although separated from the rest of the accumulated banknotes, the banknotes above the lowest banknote may also be displaced laterally at the same time due to the friction between the banknotes. The leading edge of the banknote to be discharged is pushed out to the pressure contact winding area 6 of the pressure contact type double feed prevention device 7, and when the roller peripheral surface other than the friction material 4a is in contact, the frictional force is generated. One or more bills that have been fed out are stopped in the pressure contact winding area 6, but when the friction material 4a comes into contact, only the contacted bills are taken up due to the frictional force and the outside of the roller 4 is reached. It is being sent to.

By the way, since the pressure contact type double feed preventing device 7 itself can be constituted by a small number of parts such as the pressure contact drive roller 4 and the pressure contact non-rotating roller, it has the advantages of simplicity of structure and no adjustment, but pressure contact entrainment. In the area 6, the pressure contact force is strong to prevent double feed (overlap feed) and elastic crushing occurs, so if the supply force (pressing force) of the banknote to the pressure contact winding area 6 is not strong, it is rolled up. A mistake, that is, a paper feed failure is likely to occur. Therefore, when the pressure contact type double feed prevention device 7 is used, the pressing force of the bill against the pressure contact winding area 6 must be strong in principle.
Therefore, it is essential to increase the frictional force of the bill ejecting roller 3 in order to enhance the paper ejection force of the bill ejecting roller 3. As shown in FIG. 8A, when the amount of banknote deposits is large, a sufficient load is applied to the roller peripheral surface of the banknote kicking roller 3, so that a considerable frictional force can be obtained.
As shown in (b), when the amount of banknote deposits decreases, the load also decreases, so the frictional force is proportionally weakened, and pressure contact type double feed prevention is performed despite the remaining amount of accumulated banknotes to some extent. In some cases, the paper cannot be fed from the device 7.

In order to eliminate such a paper feeding failure, the conventional bill payout device has a structure in which the load applying mechanism 10 is attached to the upper part of the storage unit 3, and even if the amount of deposits of bills becomes small, A sufficient load is applied to the roller peripheral surface of the kicking roller 3 to prevent the frictional force from disappearing and to prevent the pressure contact type double feed preventing device 7 from being caught in the wrong position.

[0007]

However, the above-mentioned conventional bill payout device has the following problems.

When the amount of banknote deposits is large as shown in FIG. 8A, both the heavy load of the banknote deposits and the strong load of the load applying mechanism 10 are applied to the roller peripheral surface of the banknote kicking roller 3. Therefore, the burden on the bill ejecting roller 3 becomes much larger than the conventional one, and it is necessary to use a separating device such as a roller having a robust and durable structure, and abrasion of the friction material 3a itself poses a problem, resulting in a long life. Also becomes shorter. Furthermore, the use of drive motors with high output torque is obligatory.

When replenishing bills, the load applying mechanism 10
Since it is necessary to temporarily remove or retreat from the upper part of the storage unit 2, no load is applied during that time.
There is no choice but to stop the bill payout operation. Since the replenishment of banknotes is performed when the amount of accumulated banknotes is small, the fact that the payout operation is stopped at this time is caused when the amount of accumulated banknotes is small in the banknote dispensing device that does not include the load applying mechanism 10. It is the same situation as the impossible situation.

In view of the above problems, an object of the present invention is to replenish sheets such as banknotes at any time without providing a load applying mechanism, and as long as there is a remaining amount of accumulated sheets in the storage section. An object of the present invention is to provide a sheet feeding device capable of reliably feeding a sheet from a pressure contact type double feed preventing device.

[0011]

In order to solve the above-mentioned problems, the means taken by the present invention is such that the frictional force itself for separating the sheet from the sheet deposit is applied to the pressure-contact winding part of the pressure-contact type double feed preventing means. Instead of using it as a feeding force for the separated sheet, the separated sheet is received without resistance, and the sheet is sandwiched and the leading edge of the sheet is directly pressed against the pressure contact winding area of the pressure contact type double feed preventing means. Where it is.

That is, according to the present invention, a storage unit for accumulating and accumulating sheets, a sheet separating means for discharging a sheet laterally from a bottom discharge port by bringing a friction material into contact with the bottom surface of the accumulated sheet, and a discharge unit A sheet feeding device including a pressure-contact type double feed preventing means for receiving the leading edge of the fed sheet in the pressure-contact winding area of the pressure-contact drive roller to prevent the accompanying sheet from advancing and feed the sheet one by one. Then, in the middle of the sheet conveying path from the bottom discharge port to the press contact winding area, an operation for temporarily generating a margin space to be received by receiving the leading edge side of the sheet discharged from the bottom discharge port and It is characterized in that a sheet insertion assisting means for repeating the operation of sandwiching the received sheet and pressing it against the pressure contact winding area is provided.

Here, the sheet insertion assisting means may use a weight body in order to increase the force for sandwiching the sheet, but in place of this, it may be provided with elastic means for giving an elastic force. desirable.

As the sheet insertion assisting means, there are sheet abutting means located above the sheet conveying path and having a sheet sliding surface, and below the sheet conveying path, and a friction material pushing-up operation and a lateral feeding operation. And a frictional material circulation locus moving means for performing the pulling-back operation in one cycle. The sheet contact receiving means may be a movable seat receiving means which includes the elastic means and in which the seat sliding surface is supported so as to be vertically movable. Here, the sheet movable contact receiving means may be a sheet swing contact receiving means having a swingable sheet sliding surface, or may be a sheet elevating contact receiving means having an ascendable sheet sliding surface. good.

Further, the sheet abutting receiving means is a sheet fixed abutting receiving means in which the sheet sliding surface is fixed, and the friction material circulation locus moving means may be provided with the elastic means.

[0016]

Since the sheet insertion assisting means is provided immediately before the pressure contact type double feed preventing means, the supply force to the pressure contact winding area of the sheet is the pressing force with the sheet being clamped and sufficient insertion is possible. The force can be secured, and the press-contact type double feed preventing means does not have a winding defect, and the sheets can be fed one by one reliably.

By the way, when the sheet insertion assisting means is constituted by the winding roller or the like, it is difficult to strongly pinch the leading edge of the sheet discharged from the discharge port. This is because the pressure contact force must be made strong in order to firmly pinch it, but if the pressure contact force is made strong, sheet winding defects will occur, as in the case of the pressure contact type double feed preventing means. However, in the present invention, a margin space is temporarily generated in advance, and the leading edge side of the sheet is inserted thereinto in a non-resistance state to be received, and thereafter, the sheet is sandwiched, so that the sheet is secured. And strong insertion can be achieved.

Therefore, according to the present invention, since it is not necessary to attach a load applying mechanism to the storage portion, it is possible to replenish sheets such as bills at any time. In particular, since the frictional force of the separating means can be reduced as compared with the conventional one, it is possible to prolong the service life of the separating means and to use a drive motor having a low output torque.

When the sheet insertion assisting means has elastic means for applying elastic force, inertia can be suppressed as compared with the case where a weight is used, so that speedup can be realized.

[0020]

Embodiments of the present invention will now be described with reference to the accompanying drawings.

[Embodiment 1] FIG. 1 is a side view showing a bill payout device according to Embodiment 1 of the present invention. The banknote payout device of this example includes a box-shaped storage section 2 for accumulating and storing a large number of banknotes 1, and a banknote surface exposure hole 8 opened on the bottom surface of the storage section 2.
A rubber bill ejecting roller 13 as a separating means for ejecting the roller peripheral surface into the inside, contacting the bottom surface of the banknote deposit and laterally shifting the banknote from the bottom discharge port 2a, and the bottom part. A pressure contact drive roller (feed roller) 4 on the lower side in which a friction material 4a such as rubber is attached to a part of the peripheral surface of the roller in the front of the banknote conveyance path from the discharge port 2a, and an upper pressure contactless rotation roller formed by a sponge or the like ( Friction roller) 5, and presses the leading edge of the banknote ejected in the pressure contact winding area 6 between them to block the entry of the accompanying banknote and to contact the friction member 4a to move the banknote outward one by one. Is provided in the middle of the banknote transport path 12 from the pressure contact type double feed prevention device 7 for sending out to the pressure contact type entrainment area 6 of the pressure contact type double feed prevention device 7 from the bottom discharge port 2a, and from the bottom discharge port 2a to the storage part. Outside of 2 A bill insertion assisting device 20 that repeats an operation of temporarily generating a margin gap G to be received by receiving the leading edge side of the appearing bill and a subsequent operation of firmly holding the bill and pressing it against the pressure contact winding area 6. Have

The bill insertion assisting device 20 of this embodiment rotates synchronously via the bill ejecting roller 13 and the transmission belt 13b, and has a lower intermittent feed friction in which a friction material pad 22a such as rubber is attached to a part of the peripheral surface. It has a car 22 and a swing type elastic pressure applying mechanism 24 provided directly above this. The leading edge side of the banknote supported by the outlet side receiving section 2b on the bottom surface of the storage section 2 is also supported by the banknote leading edge receiver 26 in the vicinity immediately before the press contact winding area 6. A friction material withdrawal hole 28 is formed between the discharge port side receiving portion 2b and the bill tip receiving portion 26 so that the friction material pad 22a of the intermittent feed friction wheel 22 can rotate in and out. The intermittent feed friction wheel 22 and the pressure contact drive roller 4 rotate synchronously via the transmission belt 4b. On the other hand, the oscillating elastic force applying mechanism 24 includes an oscillating pressing member 24b that can oscillate about a pivot 24a and a coil spring 24c that elastically urges the oscillating pressing member 24b downward.
And a support frame 24d having a stopper piece that regulates the swinging range of the swinging pressing member 24b.

When the pressure contact drive roller 4, the intermittent feed friction wheel 22, and the bill ejecting roller 13 are synchronously rotated in the state before the banknote separation shown in FIG. 1A, as shown in FIG.
The lowest banknote among the accumulated banknotes is discharged laterally by the banknote kicking roller 13 and the friction material pad 22a of the intermittent feed friction wheel 22 is retracted right below the friction material retracting hole 28. A marginal gap G is generated. Therefore, this margin space G is provided on the leading edge side of the discharged bill.
Entered and accepted in a non-resistance state. Then, Figure 1
As shown in (c), when the thick friction material pad 22a is raised by the rotation of the intermittent feed friction wheel 22 through the friction material recess / eject hole 28, it enters the clearance G and receives the received banknotes by the rocking pressing member 24b. It is strongly sandwiched between Since the swinging pressing member 24b is elastically biased by the coil spring 24c, it floats up according to the amount of protrusion of the friction material pad 22a. During this time, the bill is strongly sandwiched by the pressure of the coil spring 24c while the friction material pad 22a is being pressed. Is rotated to press the leading edge thereof toward the press contact winding area 6.

As described above, since the bill insertion assisting device 20 provided immediately in front of the pressure contact type double feed prevention device 7 makes the insertion force strong due to the transitional nip transfer of the bill to the pressure contact winding area 6. Therefore, the press-contact type double feed prevention device 7 does not cause a winding failure, and the sheets can be reliably fed one by one. Since it is not necessary to attach a load applying mechanism to the storage unit 2, bills can be replenished at any time. In particular, since the frictional force of the bill ejecting roller 13 as the separating device can be reduced as compared with the conventional one, the burden on the bill ejecting roller 3 is reduced, and the life of the roller can be extended. A drive motor with low output torque can be used.

Here, a weight body may be used in place of the swing type elastic pressure applying mechanism 24. However, when the paying-out speed is increased, the vertical movement frequency of the weight body becomes high, so that it becomes impossible to follow the pinching timing due to inertia. Therefore, when a weight is used, it is suitable for low speed payout. A structure in which the pressing member is pressed downward by an elastic means such as a coil spring is more suitable for high-speed payout since the inertia can be suppressed. If necessary, a leaf spring that also serves as the coil spring 24c and the pressing member 24b may be used.

For example, the pivot 24a has a double feed preventing device 7
When the friction material pad 22a is moved away from the swing pressing member 24b, when the friction material pad 22a moves away from the swing pressing member 24b,
b loses its support and falls on the stopper piece with a slight drop. However, since the pivot shaft 24a of the rocking pressing member 24b in this example is located on the bottom discharge port 2a side, when the friction material pad 22a is separated from the rocking pressing member 24b, the rocking pressing member 24b is moved. Has returned to the state of being stopped by the stopper piece. For this reason, it is possible to reduce damage to the swinging pressing member 24b and the stopper piece and the occurrence of abnormal noise.

The difference from the first embodiment is that the elastic pressure mechanism is changed from the swing type to the lift type. In the swing-type elastic pressure applying mechanism 20 of the first embodiment, since the contact point is near the pivot 24a when the friction material pad 22a starts to contact the swing pressing member 24b, the arm length of the moment is If the torque is short and the friction wheel 22 has a relatively high torque, it is difficult to push up the swing pressing member 24b. However, in the lifting type elastic pressurizing mechanism 34 of this example, since there is no pivot, the length of the arm for moment does not matter, and there is an advantage that the torque of the friction wheel 22 can be relatively low.
