into the ring. In order to ensure that the turret stops with the cup stack positioned
centrally over the ring, the carousel micro-switch is activated by a series of levers on
the turret. By ensuring that both the cup empty and carousel micro-switches are off,
the controller always stops the turret in the correct position.
Two features of the controller program assist in the operation of the cup mechanism:
1. To prevent the customer having to wait for the cup stack to rotate into position
after the cup empty micro-switch activates, one further vend can be made before
the “out of cups” message is displayed, allowing the next cup stack to move into
position.
2. Should the cup turret jam or be empty, the cup indexing motor would continue to
run and eventually burn out. To eliminate this, a ninety second time-out has been
incorporated after which time the machine will be set into the disabled state and
display the “out of cups” message.
The flow chart below shows the general operation of the cup mechanism.
