BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoisting device for collecting medals discharged from a game machine such as a slot machine by a collecting conveyor and hoisting them into a tank in a medal supply device body.

[0002]

2. Description of the Related Art As a conventional lifting device, there is one as shown in FIGS. The one shown in FIG. 3 is a conveyor for collecting medals discharged from a game machine such as a slot machine (1)
Transferred by a lift (3) through a chute (2)
Be thrown into. The lift is composed of belts (7) having bars (4) arranged at regular intervals and stretched between pulleys (5) and (6), and medals thrown by the bars (4) of the lift (3) are It is designed such that it is lifted and put into a tank (10) having a payout machine (9) from an upper chute (8). Further, in the structure shown in FIG. 4, medals discharged from a game machine such as a slot machine are transferred by a collecting conveyor (1), and are accumulated in a medal hopper (11) via a chute (2) and a mouth of an escalator (13) ( 12)
Therefore, the medals are lifted and inserted into a tank (15) having a payout machine (16) from an upper chute (14).

[0003]

In the lift shown in FIG. 3, it is necessary to collect the accumulated medals because the medals spill from the crosspiece (4) and the medals are accumulated on the bottom of the lift, which makes the lift unrotatable. It is difficult because there is no space under the lift (3). In the case of the one shown in FIG. 4, medals are easily clogged in the escalator (13), and when deformed medals enter the escalator (13), they are often clogged, and the escalator must be disassembled to remove it, which is troublesome for recovery. . Further, as shown in FIG. 5 in both FIGS. 3 and 4, there are two recovery conveyors (1) on both islands, and when the medals from both are guided to the lift or the medal hopper (11) by the chute (2), there is a difference in height. Since there is no such thing, the minimum inclination of 30 ° can not be caught and the medal does not flow smoothly. Further, it is desirable to store a large amount of medals in the tank, but since the medals are paid out from the pay-out machine to the calendar lifting machine as shown in FIG. 2, the height of the bottom of the tank becomes a certain height. Therefore, the capacity of the tank is limited, and the space below it is wasted. 3 does not have a tank function, and FIG. 4 is limited to a maximum of 1000 sheets, for example. Further, since both the lift and the medal hopper are located in the lower part of the island, it is difficult to perform maintenance in case of trouble. Therefore, this plan is easy to maintain without trouble.
Moreover, it is an object of the present invention to provide a lifting device that can take a sufficient space in the tank.

[0004]

In order to achieve the above-mentioned object, the present invention provides the following lifting device. That is, the medals supplied from the medal carrier are used in the game machine, the medals used in the game machine are collected in the collection tank by the collection conveyor, and the collected medals are collected in the payout tank by the lifting device that can remove dust. In a medal replenishing device in which the medals that have been transferred and then passed through a medal polishing machine and a medal polishing agent separator from the payout tank are returned to the medal carrier, the lifting system is placed in a vacuum pump chamber equipped with a filter. The medal absorption chamber is provided adjacent to the medal absorption chamber, and the medal absorption chamber is provided with an absorption hose that opens to the front of the filter and a lid that is opened and closed by a lid opening / closing device. It is the lifting device.

[0005]

Function: The medals absorbed by the vacuum hose equipped with the filter through the absorption hose are removed by the filter and discharged into the absorption chamber, and the medals accumulated in the absorption chamber are opened and closed by the lid opening / closing machine. It is discharged to the tank.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below. The lifting machine of the present invention is as shown in FIG. 1, and a medal absorption chamber (20) is arranged adjacent to a vacuum pump chamber (18) equipped with a filter (19). Is an absorption hose (1
There is a lid (22) provided with 7) and opened and closed by a lid opening / closing machine (21). The lifting device of the present invention is configured as described above, and the medal is sucked up into the absorption chamber (20) by the vacuum pump (18) through the absorption hose (17) and mixed into the medal in the absorption chamber (20). The dust thus collected is absorbed by the vacuum pump (18) through the filter (19). The medals from which dust has been removed are discharged into the tank (28) by a signal from the lid opening / closing device. Such a lifting device is
As shown in FIG. 2, it is provided above the tank in the main body (A) of the medal supply device at the island end.

Therefore, a system diagram using the device of the present invention shown in FIG. 2 will be described. The medals discharged from the game machine (23) such as a slot machine through the discharge bellows (26) are transferred by the recovery conveyor (1) and discharged to the recovery tank (27), and the tank (28) is lifted by the lifting device of the present invention. The medal collected in the recovery tank (27) is sucked up by the suction hose (17) by the vacuum pump (18), and the medals whose dust has been removed are absorbed in the absorption chamber. It falls to (20). Absorption chamber (2
The medals accumulated in 0) open the lid (22) in response to a signal entering the lid opening / closing device (21), and eject the medals to the tank (28). The medals accumulated in the tank (28) are sent from the medal polisher (30) to the medal polisher separator (31) through the chute (34) by the payout machine (29),
The polished medal is sent from the chute (32) to the medal carrier (33) and is replenished from the replenishing bellows (24) to the hopper (25). The lifting device of the present invention is provided in the medal replenishing device as described above, and the dust of the medals sucked up by the absorption hose into the absorption chamber is absorbed by the vacuum pump. ) Is discharged inside.

[0008]

Effect of the Invention The present invention has the following effects. (1) By using the present invention, since the recovery tank can use the lower part of the tank and the lower part of the game machine on the island as necessary, the medal storage device can sufficiently cover the medal supply device. (2) By using this plan, medals from the collection conveyor need only be put into the collection tank, so even if a problem occurs with the system of this plan, it will continue without any hindrance to business on the island. To be (3) Since the medals returning from the collection conveyor are often mixed with dust, they tend to be clogged with conventional lifts, coin hoppers, tank dispensers, polishing and lifting machines, etc., causing troubles. In this plan, these troubles can be prevented because they are removed by a filter. (4) Since the lifting device according to the present invention is housed in the main body provided at the end of the island, even if a trouble should occur, maintenance can be performed without affecting business on the island. (5) Even if there are two collection conveyors on both islands, the medals can be collected smoothly without dropping the medals, since the medals can be dropped directly from each collection conveyor into the collection tank. (6) The lifting device including the vacuum pump of the present invention can be housed in the medal supply device body. That is, the medals collected in the collection tank are merely raised to a height, and the medals can be small in size, and thus can be stored in the medal supply device body. If the lifting device is not housed in the medal supply device body, it is difficult to install the blower in another place and guide it by the transportation pipe in the hall because of the ventilation pipes in the hall.
