  • The WGR - a coin handling carrousel - has two specific functions. It not only stores coins, acting as an escrow to return rejected coins, but also serves as a payout mechanism.
  • The escrow returns the originally entered coins, so acts as a Last- In, First-Out (LIFO)mechanism. These features are so constructed to offer the user optimal security in coin handling.
  • The modular design of the WGR allows several carrousels to be placed on top of each other by using a simple rack construction, resulting in a complete coin storage and payout system.
  • The WGR is a cylindrically designed magazine with 54 compartments in which 50 entered coins can be stored. The carrousel´s mechanical design allows all coin handling to take place within the unit. Coins that enter into the WGR do not require an additional rundown. This also applies to coin overflow and coins that are rejected
  • by the validator. All coins pass through the magazine(s).
  • The magazine is powered by a bi-directional drive motor which is linked to a pinion. The motor can drive the magazine both forwards and backwards. The current motor position, which is correspondingly the current compartment position, is monitored by a slotted optical switch and this information is sent to the CPU. It is thus possible to position the motor so that the next empty compartment is in the accept position for the next entered coin.
  • As soon as the coin is accepted by the validator an electro-magnetic shutter closes the coin channel of the magazine that is to accept the coin. The positioning of the shutter
  • is also monitored by LEDs
  • To install the magazine, simply slide it into a slot on the rack. This is connected to the machine via a D-SUB connector at the back of the magazine. To ensure optimal connector contact, the PCB is placed in a floating position.
  • It is standard practice to insert several WGR carrousels on top of each other to form a coin handling system. Each separate coin value is thus assigned to a separate magazine. A CPU controls the whole process and drives the magazines.
  • A sensor is positioned underneath the validator to recognise coins that enter the system. It sends a signal to the CPU, and once the system’s set-time has elapsed, the CPU will let the validator accept further coins. In the WGR carrousels the coins also first pass through a coin entry LED (LS1) which is connected to the CPU.
  • Once a coin has been accepted, the CPU instructs the relevant magazine to close the shutter via magnets and the motor turns the carrousel in the coin accept position. This coin is now stored. The relevant motor/compartment position is controlled by an opto finger on the drive motor’s pinion via a slotted optical switch.
  • If the purchase is cancelled in mid-vend, then coins that have already been entered are returned. The CPU instructs the motor in the magazine to turn anti-clockwise. In this way the last entered coins are the first to be returned (LiFo principle).
  • If all compartments are full in the magazine, then the coin that was first accepted reaches the overflow opening in the base of the WGR magazine, and consequently falls through the opening when the next coin enters the magazine. As each magazine is placed directly on top of each other, the coin will fall through the magazine under it and thus into the cashbox.
  • A coin exit sensor is inserted underneath the magazines to ensure that the CPU is informed of any misrouted coin.
  • Coin validator, coin entry and exit sensors and cashbox do not form part of the magazine delivery programme and are therefore necessary additional system components.
