Description

[Detailed Description of the Invention] This invention relates to a paper sheet conveying device used in a paper sheet dispensing device or the like.

Conventionally, as a paper sheet dispensing device, there is, for example, a banknote dispensing device. This bill dispensing device is configured to suction and separate bills one by one from a bill stacker and then dispense them to a dispensing port using a conveying device.
Moreover, this bill dispensing device is equipped with a slip issuing device, and the slip issuing device sends a receipt on which the amount of the bill dispensed and the like is written to the conveying device.

However, since the delivery roller that sends out the receipt from the slip issuing device and the transport roller that transports the receipt sent out by this delivery roller to the transport device are driven separately, for example, the rotational speed of the delivery roller is different from that of the transport roller. If the rotation speed is slower than the rotating speed, the receipt is pulled by the delivery roller and the conveyance roller, resulting in a problem that the receipt slips or is torn.

This idea was made in view of the above circumstances, and its purpose is to prevent paper sheets from slipping or tearing even if the drive sources for the delivery roller and the conveyance roller are separate. It is an object of the present invention to provide a paper sheet conveying device capable of conveying paper sheets smoothly and reliably.

Hereinafter, one embodiment of this invention will be described in detail based on the drawings. FIG. 1 shows a banknote dispensing device,
This banknote dispensing device sequentially sucks and separates banknotes one by one from a banknote stacker 1 loaded by denomination using a suction swinging rod 2 and sends them out to a conveying device 3, and transfers the sent banknotes to a stacking car 4. After feeding, the banknotes are stacked at a payout port 5, and then a shutter 6 provided at the payout port 5 is opened to dispense the stacked banknotes. In the conveyance device 3, the banknotes are conveyed while being held between a pair of first belt conveyors (hereinafter simply referred to as belt conveyors) 7, and the conveyance direction is further changed by a guide member 8. Thereafter, it is sent to a second belt conveyor (hereinafter simply referred to as belt conveyor) 9, which is also provided in a pair, and is further conveyed by this belt conveyor 9, and is delivered to the delivery port 5 via the collection car 4. There is. Further, each of the belt conveyors 7 and 9 of the conveying device 3 is configured to convey banknotes at the same speed by the same drive source (not shown).

A slip issuing device 10 is disposed above the conveying device 3. This slip issuing device 1
0, a receipt on which the amount of the bill dispensed at the dispensing port 5 is displayed is sent out to the belt conveyor 9 via the guide member 8 by a conveying device 11 (described later). That is, the conveyance device 11 includes the slip issuing device 10 and the belt conveyor 9.
a pair of delivery rollers 12 disposed between the
and a pair of conveyance rollers 13 for conveying receipts sent out from the belt conveyor 9 to the belt conveyor 9. The delivery roller 12 is driven via an overrunning clutch 14 by a drive source (not shown) separate from the drive source of the conveying device 3. By the way, as shown in FIGS. 3 and 4, the overrunning clutch 14 is configured such that when the drive source 15 rotates in the direction of the arrow (counterclockwise), the rollers 18 are pushed out by the metal springs 17 held by the holder 16. , the outer ring cam surface 19 reaches the meshing position, and the outer ring 20 rotates together with the drive shaft 15, and when the outer ring 20 rotates faster than the drive shaft 15, as shown in FIG. Thus, the rollers 18 are separated from the outer ring cam surface 19 so that only the outer ring 20 idles.

Further, the conveyance roller 13 is driven by the same drive source (not shown) as the drive source for the belt conveyors 7 and 9.

Next, the operation of the banknote dispensing device configured as described above will be explained. First, when a dispensing command is sent to the bill dispensing device, the bills corresponding to the dispensing command are suctioned and separated one by one from within the bill stacker 1 by the suction swinging rod 2, and then sent to the conveying device 3. The conveyance device 3 collects them at the outlet 5. Thereafter, when the banknotes are paid out, the receipt is sent out to the sending roller 12 by the slip issuing device 10. When the receipt is sent out to the delivery roller 12 in this manner, it is conveyed to the belt conveyor 9 via the conveyance roller 13. At this time, for example, if the rotational speed of the delivery roller 12 is
If the rotational speed is faster than the rotational speed of
The belt conveyor 9 is bent between the belt conveyor 9 and the conveyor roller 13.
transported to. Further, when the rotational speed of the delivery roller 12 is slower than the rotational speed of the transport roller, the receipt is pulled by the transport roller 13, and this stretched receipt causes the delivery roller 12 to overrun (idle). )do. That is, since the outer ring 20 of the delivery roller 12 rotates faster than the drive shaft 15, the rollers 18 rotate on the outer ring cam surface 19.
As a result, only the outer ring 20 spins idly.
In this way, when the delivery roller 12 idles,
The receipt is smoothly conveyed to the belt conveyor 9 without slipping or tearing. After this,
The receipt is dispensed to the dispensing outlet 5.

As explained in detail above, this invention is such that in a conveyance device in which the feed roller and the conveyance roller are each driven by separate drive sources, the feed roller is provided with an overrunning clutch, and the rotation speed of the feed roller is increased. is faster than the rotational speed of the conveyance roller, the paper sheet to be conveyed is bent between the feed roller and the conveyance roller and is conveyed by the conveyance roller, and the rotation speed of the feed roller is If the rotation speed is slower than the rotation speed of the conveyance roller, the paper sheet is pulled by the conveyance roller, and the feed roller is overrunning, so the conveyance device is driven by another drive source. There is an effect that when paper sheets are fed into the machine, the paper sheets can be fed smoothly and reliably without slipping or tearing. Furthermore, since the conveyance rollers provided just before the conveyance device are driven by the same drive source as the conveyance device, bills can be smoothly transferred from a mechanism driven by a drive source different from the conveyance device to the conveyance device. This has the effect that it can be carried out.
