KR970017065A - Pizza remaining amount detector of pizza vending machine - Google Patents

Abstract

The present invention relates to a pizza remaining amount detection device of a pizza vending machine that can detect the remaining amount of the pizza stored in the pizza storage rack and inform the pizza replenishment time before the pizza is sold out.

Conventional pizza vending machines are difficult to manage the pizza vending machine and lose the opportunity to sell the pizza due to the lack of a function of notifying the pizza replenishment time before the pizza is sold out by detecting the remaining amount of pizza.

Pizza remaining amount detection device of the present invention is a combination of a load sensor and an optical sensor installed in the pizza storage rack, an indicator for notifying the pizza replenishment time, and the detection signal through the load sensor and the optical sensor "on / off" ”Control unit.

In the present invention, the control unit outputs a control signal to the indicator when the condition that the detection weight through the load sensor is equal to or less than the reference set weight and the condition that the light sensor is "on" at the same time, the indicator to supplement the pizza You will be notified when.
