Abstract

PURPOSE:To make the title device lest the vibration generated by a medal- feeding means is transmitted to a medal-replenishing line by a method wherein a clearance is formed between an outlet of the medal-feeding means and an inlet of a conveying channel, and a pair of rollers are located in the clearance, and a medal discharged from the outlet is held between them and is fed into the inlet. CONSTITUTION:A medal feeder 10 is composed of a bowl 16 holding medals 14 fed from a reserved bucket 12 and a vibrator body 18 applying vibration to this bowl 16, and feeds the medals 14 to a conveying channel 20 one by one. An almost-horizontal guide surface 21 in the form of a spiral is formed on the inside of the bowl 16, and the medals 14 are gradually lifted along the guide surface 21, are gradually turned from horizontal to vertical, are arranged one by one, and are finally discharged. Since an outlet 16a of the bowl 16 is separately located from an inlet 20a of the conveying channel 20, the vibration of the bowl 16 is not transmitted to the conveying channel 20. A pair of conveying-rollers 30 made of rubber are located in the clearance part between the outlet 16a and the inlet 20a, and feeds the medals into the conveying line 20.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a system for transporting medals and coins to game machines and money exchange machines, and more specifically, to a system for transporting medals and coins to game machines and money exchange machines, and more specifically, to a system for transporting medals and coins to a game machine or a currency exchange machine. It concerns improvements to the supply system.

[Conventional technology]

The medal replenishment system stores a large number of medals in a predetermined container, and transports and supplies them to each device from there. In such a medal supply system, in order to feed the medals one by one into the medal supply path, conventionally, for example, a retaining pin with a thickness less than one medal is provided protruding from the surface of the disk, and this disk is inserted into the medal storage packet. It used a hopper device that rotated at the bottom.

However, in such a medal supply system using a hopper device, there is a problem in that the hopper device has a high malfunction rate.

Therefore, the present applicant has already developed a system in which a medal feed means is provided in front of the medal supply route, which feeds the medals by mechanically vibrating a bowl formed with a spiral guide surface, thereby supplying medals to the supply route. (Japanese Patent Application No. 63-283087).

[Problem to be solved by the invention]

However, in the above-mentioned system, the vibration of the medal feeding means reaches not only the conveyance rail but also the game machine and the exchange machine, which has a disadvantage in that it adversely affects the operation of each of these devices. Another problem arose in that the noise caused by vibration was large.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a medal supply system in which vibrations generated in the medal feeding means are not propagated to the medal supply path.

[Means for Solving the Problems] In order to achieve the above object, the present invention forms a gap between the discharge port of the medal feeding means and the receiving port of the conveyance rail, and also provides a means for discharging from the discharge port into this gap. A pair of rollers is installed to sandwich the medals and feed them into the receiving opening.

[Function] Since the present invention is configured as described above, even if the medal feeding means vibrates when replenishing medals, the vibration is suppressed through the gap between the medal discharge port of the medal feed means and the suction port of the transport rail. The vibration of the medal feeding means is not transmitted to the transport rail.

Moreover, since the medals discharged from the medal feeding means while vibrating are sent out while being held between the pair of rollers in the gap between the medal feeding means and the transport rail, the medals are reliably fed to the transport rail.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 shows the overall configuration of the medal supply system according to this embodiment. In the figure, the medal feeder 10 is composed of a bowl 16 that accommodates medals 14 supplied from a spare packet 12, and a vibrating body 18 that vibrates the bowl 16.
Send out one sheet at a time. Since the medal feeder 10 is generally placed near the ceiling of a building, the medals 14 are transported to the reserve packet by a transport device such as a lift.

As shown in FIG. 3, the bowl 16 has a spiral, substantially horizontal guide surface 21 formed on its inner surface, and the medals 14 are gradually carried upward along this guide surface 21 by the vibration of the bowl 16. It will be done. Then, the uppermost stage 22 of the guide surface 21
is inclined inward, and a jaw 24 is formed on the receiver corresponding to the thickness of one medal, and the medals 14 that have been conveyed along the guide surface 21 are gradually raised from a horizontal position and placed one by one. They are arranged to be ejected. Further, the bottom surface 26 of the bowl 16 has a raised central portion so that the stacked medals 14 are moved closer to the periphery by vibration.

The vibrating body 18 is installed on a base 28 with rubber feet 30 for vibration isolation, and is vibrated in the lateral direction by a built-in magnetic drive device 32.

As shown in FIGS. 1 and 4, the discharge port 16a of the bowl 16 and the transport rail 20 are both formed to be slightly wider than the width of the medals 14, so that the medals 14 can be loaded one by one without causing medal jams. Transport is ensured. In addition, the discharge port 16a of the bowl 16 and the conveyor rail 1
The receiving ports 20a of No. 6 are arranged apart by a length l,
Care is taken to prevent the vibration of the bowl 16 from being transmitted to the transport rail 20. Note that the value of l is preferably about BIT II 11 when the outer diameter of the medal 14 is 25 mm.

Discharge port 16a of bowl 16 and receiving section 2 of conveyor rail 20
A pair of rubber conveyance rollers 30 are arranged in the gap 0a in order to send out the medals 14 sent from the bowl 16 to the conveyance rail 20. The pair of conveyor rollers 30 are spaced apart from each other by a distance slightly narrower than the thickness of the medal 20 (for example, about 1.6 mm),
The medals 14 are biased toward each other by biasing means (not shown) so that the medals 14 are reliably held.

Then, the conveyance roller 30 is transferred to the motor vehicle 3 via the belt 32.
Rotating force is transmitted from 4 to rotate at high speed and forcefully send out the medals 14 to the conveyance rail 20 side.

A sender 3 is placed at an appropriate interval along the conveyor rail 16.
6 are arranged, and thereby the medals 14 are transferred on the transport rail 16. This feeder 36 is composed of a feed roller 38 that presses the medal 14 from both sides, and a motor 40 that rotationally drives this roller 38, and the rotation of the feed roller 38 transfers the medal 14 to the right at a constant speed. Note that this feeding speed corresponds to the speed at which the medals 14 are discharged by the medal feeder 10.

Reference numeral 42 denotes a dispenser, which transports and supplies the medals 14 sent to the transport rail 20 to the slot machine 44 and the medal lending machine 46. That is, the dispenser 42
is for adjusting the sending direction of the medals 20 being conveyed, and is configured to switch the internal supply route in response to a supply signal from the slot machine 44 or the medal lending machine 46.

Next, the operation and effect of the embodiment configured as above will be explained.

After the medals 14 are transported to the spare packet 12 by a transport device (not shown), the power to the medal feeder 10 is turned off.
Set it to N. When the medal feeder 10 is turned on,
The magnetic drive device 32 is activated and the bowl 16 begins to vibrate. As a result, the medal 14 accommodated at the bottom of the bowl 16
moves on the spiral guide surface 21 and rises. Then, the medals 14 are erected one by one at a predetermined angle on the uppermost stage 22 of the guide surface and are ejected from the ejection port 16a.

Next, the medals 14 are ejected from the ejection port 16a of the bowl.
A pair of transport rollers 30 rotating at high speed send the paper to the transport rail 20 from the receiving section 20a separated by l. In this way, the discharge port 16a of the bowl 16 and the conveyor rail 20
Since the receiving portions 20a of the medal feeder 10 are arranged at a distance of l, the vibration of the medal feeder 10 is not propagated to the conveyance rail 20.

Moreover, even if the discharge port 16a vibrates to some extent, the medal 14
As long as it is sent between the conveyance rollers 30, it can be reliably sent to the receiving section 20a.

Next, the medals 20 sent into the transport rail 20 are supplied to each device that requires replenishment by the action of the dispenser 42. That is, the slot machine 44. The medal lending machine 46 outputs a replenishment signal when the amount of medals held falls below a certain amount, and the dispenser 42 switches the replenishment route accordingly and supplies the medals 14 to devices that require replenishment.

As described above, since the vibrations of the medal feeder 10 are not transmitted to the transport rail 20, the delivery device 36°, the dispenser 42. The medal lending machine 46 and the slot machine 44 can be operated properly at all times without adversely affecting their operation.

Thereafter, when the number of medals 14 in the reserve packet 12 becomes less than the specified amount, the reserve packet 12 is replenished with medals 14.

〔Effect of the invention〕

As explained above, in the present invention, since a predetermined gap is provided between the discharge port of the medal feeding means and the receiving port of the conveying rail, the 4° vibration of the medal feeding means is blocked by the gap, and the conveying rail This has the effect of preventing any adverse effects on the subsequent operation of each device.

Furthermore, since the pair of rollers is arranged within the gap, the medals discharged from the medal feeding means while vibrating can be reliably fed to the conveyance rail.
