[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine, a vending machine, and the like (hereinafter, simply referred to as a vending machine, etc.) for accepting bills inserted by a user and discharging returned bills and fishing bills. It relates to a bill taking-in / discharging unit.

[0002]

2. Description of the Related Art As a conventional bill processing apparatus in a vending machine or the like, bills (thousand-yen bills, 5,000-yen bills, 10,000-yen bills) as described in, for example, JP-A-62-83933. When the bills are taken in one by one, identified, stored by denomination, and returned (discharged) for fishing bills, the 1,000-yen bills stored in the 1,000-yen bill storage section are fed out as fishing bills, and the extracted bills are taken out. 2. Description of the Related Art There is known an apparatus in which a case is sent to a storage case, and the case is rotated and taken out.

[0003]

However, the above-mentioned conventional banknote handling machine has the following problems.

(A) Since the take-in mechanism and the return mechanism or the discharge mechanism are provided separately, the insertion position and the return position are separated from each other, so that the operability is poor for the user and the drive mechanism And the like must be provided, which leads to a complicated structure and an increased cost.

(B) Since only one bill can be inserted, it is inconvenient to insert a plurality of bills.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a simple structure, low cost, good operability, and a plurality of bills in a vending machine. The purpose is to be able to insert bills in a lump.

[0007]

According to the first aspect of the present invention, a bill taking-in / discharging portion of a vending machine or the like according to the first aspect of the present invention is disposed forward and backward, and a pair of pulleys at least one of which is driven is wound between the pulleys. A turned endless belt having a friction surface on the outer periphery,
An upper roller disposed above the pulley on the front side with the endless belt interposed therebetween, supported rotatably and movably in the vertical direction, and urged toward the endless belt,
A lower roller disposed below the front pulley with the endless belt interposed therebetween, supported rotatably and movably in the vertical direction, and urged toward the endless belt;
A drive transmission unit that connects the upper roller and the lower roller to each other so as to transmit one rotation to the other roller, and a first power transmission unit formed behind the upper roller.
A bill holding portion and a second formed behind the lower roller.
And a bill storage unit.

[0008] The bill taking-in / discharging unit of the vending machine or the like according to the second aspect of the present invention is disposed forward and backward, and a pair of pulleys at least one of which is driven; An endless belt having a friction surface on the outer periphery, and an upper roller disposed above the front pulley with the endless belt interposed therebetween and supported rotatably and vertically movable,
A lower roller disposed below the front pulley with the endless belt interposed therebetween and supported rotatably and movably in the up and down direction, and wound between a rotation axis of the upper roller and a rotation axis of the lower roller. The drive transmission belt is rotated to transmit rotation to each other, and presses both rollers against the front pulley by its own elasticity, a first bill storage unit formed behind the upper roller, and the lower roller. And a second bill holding portion formed at the rear.

[0009]

According to the first aspect of the present invention, one or a plurality of bills are inserted into a bill take-in / discharge unit of a vending machine or the like, for example, between a lower roller and an endless belt. Then, the endless belt is driven, and the inserted bill is held between the lower roller and the endless belt and taken in.
At this time, the upper roller rotates in the opposite direction by being pressed against the friction surface of the endless belt, and the rotation is transmitted to the lower roller by the drive transmission means. As a result, the endless belt and the lower roller holding the bill rotate together in the take-in direction. As described above, since both the endless belt and the lower roller rotate at the time of taking in banknotes, even when the inserted banknotes are large and thick, stable holding / conveying is possible. Then, the taken-in banknote is held in the second holding unit, and is subjected to subsequent processing. Further, in this case, when returning or paying out the bills, the bills held in the first holding unit are nipped and conveyed by the upper roller and the endless belt, and are discharged. At this time, the lower roller is rotated by being pressed against the friction surface of the endless belt, and the rotation is transmitted to the upper roller. Since both the endless belt and the upper roller that hold the bills rotate in the discharge direction, stable clamping / discharging is possible even when the number of discharged bills is large and thick. Note that the above is the operation when the intake mechanism is configured for the lower roller and the discharge mechanism is configured for the upper roller.
Conversely, there is a case where the intake mechanism is formed on the upper roller and the discharge mechanism is formed on the lower roller. In this case, the upper and lower positions are changed, but the operation is the same.

The operation is the same in the case of the bill taking-in / discharging section of the vending machine or the like according to the second aspect of the present invention. In this case, the drive transmission belt that rotationally connects the upper roller and the lower roller urges both rollers toward the endless belt due to its own elasticity, so that the number of bills to be inserted or ejected is large and thick. As a result, the drive transmission belt is stretched, and the force for holding the bill increases. for that reason,
Even if the number of banknotes is large, stable take-in or discharge is possible.

At this time, the feeding mechanism is driven, and the pressed highest bill is fed and sent to the descending conveyance path 154.

When two sheets are fed out due to poor feeding, the bill is sent from the third branching section 158 to the third branching conveyance path 161. At this time, the push-in member 147 of the 5,000-yen bill storage unit is raised in conjunction with the elevation of the movable push-in member 84 of the 5,000-yen bill storage / feed-out unit, and the banknote conveyed along the third branch conveyance path 161. The (dispensing reject bill) enters under the pushing member 147 and is stored in the dispensing reject bill storing unit 134.

Then, the normally fed bills pass through the descending conveyance path 162 and are accumulated in the dispensed bill storage unit 135 as shown in FIG. Then, when the number of 1,000 yen bills to be dispensed is accumulated in the dispensing bill storage unit 135, as shown in FIG. 8B, the dispensing bill storage unit 135
The holding roller 152 is lowered, and the take-in / discharge belt 166 is driven in a counterclockwise direction, and the bills held in the pay-out bill holding unit 135 are conveyed forward, and the upper holding roller 168 and the take-up rollers 168 are taken in. The sheet is held and transported by the discharge belt 166. At this time, the intake / discharge belt 16
6, the lower pinching roller 167 is driven to rotate, and the rotation is driven by the drive transmission belt 66.
Is transmitted to the upper nip roller 168 via the, and the upper nip roller 168 rotates clockwise. In this way, since both the take-in / discharge belt 166 for holding the bill and the upper sandwiching roller 168 rotate in the direction for sending the bill, even when sending a plurality of bills, the bill is discharged without being separated. . Also, when the number of bills to be discharged is large and thick, the upper sandwiching roller 168 is lifted according to its thickness, and the drive transmission belt 166 is stretched, so that the upper sandwiching roller 167 is elastically attached to the lower side. Since the force of the force increases, the force of holding the bill increases. Therefore, even if the number of bills increases, stable discharge is possible.

The sent bill pushes and opens the closing portion 69b of the shutter member 69 to protrude forward as shown in FIG. 8C, and the shutter member 69 moves the closing portion 69b downward by the weight of the bill. It is pushed down, and accordingly, the holding part 6
9c is lifted to hold the bill. Then, at this time, the detection lever is rotated by being pushed by the pushing portion of the shutter member 69, and the detection lever 72 is moved by the photo interrupter 71.
Is in a light-transmitting state, indicating "there is a bill".

When the discharged bill is extracted by the user, the shutter member 69 returns to the position where the closing portion 69a closes the discharge passage, and the photo interrupter 71 is in a light-shielded state, indicating "no bill". Processing can be accepted.

[0043]

As described above, according to the present invention, since the take-in mechanism and the discharge mechanism are vertically arranged with the endless belt interposed therebetween, the insertion position and the withdrawal position of the bill are arranged at substantially the same position. In addition to improving the operability for the user, the drive mechanism of the take-in mechanism and the discharge mechanism can be used in common, so that the structure can be simplified and the cost can be reduced. With the configuration in which the rollers are urged, it is possible to stably take in and discharge a plurality of bills.

Also, by employing a configuration in which both rollers are urged by the elasticity of the drive transmission belt that rotationally connects the upper and lower rollers, the pinching force is increased as the number of inserted or ejected paper money increases and the paper money becomes thicker. Can be maintained.
