Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a coin conveying device for conveying coins for gaming in a game hall where coin game machines are installed, and in particular to a coin conveying device for conveying coins for coins, such as a coin game machine or a coin lending machine. This is effective when supplying coins to multiple devices. [Conventional technology] In gaming parlors, coin lending machines that lend out coins used by players when playing games, and coins that are paid out from coin gaming machines according to game results, are monitored based on the lending status of each coin lending machine and each coin lending machine. Each coin lending machine and each coin gaming machine must be paid according to the payout status of the coin gaming machine.

Previously, employees could directly supply coins to each device, or
A coin replenishment device is placed on the island of a game hall where coin game machines are installed, and coins are transported and supplied to coin lending machines and coin game machines that require coins. This coin conveying device can be used to push coins one by one into a coin supply tube with a cross-sectional shape that matches the width and thickness of the coin, and feed them sequentially to a coin lending machine as needed, or a belt conveyor. There are things you can use to replenish coin lending machines. [Problems to be solved by the invention] However, when trying to automatically supply coins to each of the coin game machines arranged in rows on the island, the former coin supply device has the problem that coins tend to get clogged in the coin supply pipe, and the coin supply pipe is narrow. Since the number of coins that can be sent through the coin supply pipe is limited, it is not possible to distribute and supply coins to many coin gaming machines. Further, coins need to be replenished to each coin gaming machine only according to the payout state of each coin gaming machine, and do not need to be constantly carried in. For this reason, in the latter belt-based coin replenishment device, the coins are transported once and then
If the extra coins are not carried into each coin gaming machine, they will be carried to the end of the belt conveyor. Therefore, coins that are not carried into each device must be collected using equipment such as a belt conveyor that is separate from the one used for transport. Another problem is that in order to reliably supply coins to each device, it is necessary to distribute and supply each device individually. The present invention is mainly used in a coin transport device that transports coins to coin gaming machines and coin lending machines, and is capable of reliably distributing and distributing coins to each device. To provide a direct transport system for coins that does not require separate collection even when the coins are not carried into a machine or a coin game machine.

Further, it is preferable that the sliding table has the shape of two rails arranged at a substantially regular interval, and the endless chain is arranged between the sliding table. On the other hand, it is preferable that the conveyance body has a pre-offender conveyance section arranged in a line on the conveyance path and is connected to the endless chain. Here, it is preferable that the conveyance section has an arc-shaped section that is aligned with an adjacent conveyance section. In that case, the shape of the conveyance section for continuous alignment may be approximately a crescent moon shape. Furthermore, the coin pushing means may be a rocking plate that is rotatably supported outside the transport path and swings into the transport path.

In the present invention, when the endless chain runs along the conveyance path, the plurality of conveyance bodies connected by the endless chain are driven and slide on the sliding platform to move along the conveyance path in an approximately horizontal direction. When the coin pushing means moves one step while the coin is being transported, the coin placed on the transport section of the transport body is pushed out of the transport path and sent to a device or the like.

Here, since the conveyance path forms a circulation path in a substantially horizontal direction, the coins conveyed by the conveyance body continue to be conveyed by the conveyance body forever until they are pushed out by the pushing means. .

[Effects of the Invention] In the present invention, the conveying body circulates and conveys the coins in the horizontal direction using an endless chain, so the coins can be freely conveyed over a wide range, and extrusion means are attached at necessary locations. By doing this, it is possible to reliably supply coins to each M & container. Therefore, the supply and management of coins becomes easy, and since the transported coins circulate along the transport path together with the transport body, there is no need to collect the coins when the coins are not transported to each device.

If the conveyance path is provided with a wall, the coins placed on the conveyance section can be conveyed within the conveyance path without coming out from the conveyance path.

If the sliding table forms two rails and the endless chain is arranged between the sliding tables, the shape of the circulation path can be freely set without the restriction of clockwise or counterclockwise rotation, and the conveyor can be It can be placed across between two sliding tables, so
A large number of coins can be transported in a stable state.

Furthermore, when the transport parts of a plurality of transport bodies are arranged in a row on the transport path,
