KR950030000A - Cup dispensing automatic switchgear of coffee vending machine and its driving circuit - Google Patents

Abstract

The present invention relates to a cup dispensing automatic opening and closing device and a driving circuit for automatically opening and closing a cup dispensing opening for dispensing a cup in a coffee vending machine, and particularly, after the cup dispensing opening is automatically opened and the cup is withdrawn The present invention relates to a cup dispensing automatic switchgear and a driving circuit thereof of a coffee vending machine which can automatically close the cup dispensing opening.

The cup outlet automatic opening and closing device of the present invention is a motor 20 for opening and closing the cup outlet 10 when the selling operation is completed by the user inputs a coin in a state that the cup outlet 10 is connected to the closing detection switch (SW2). ) Is driven by a drive circuit to rotate the screw bar 14 by belt transmission, and the guide rod 11 connected to the center of the bottom of the cup outlet 10 inserted into the spiral groove of the screw bar 14 is a left spiral groove line. When the cup outlet 10 is connected to the open sensing switch SW1 by guiding movement along the 14a to reach the end point of the spiral groove, the driving of the motor 20 is temporarily stopped, and then the motor 20 is driven by the driving circuit. Guide rod 11 positioned at the end point is guided along the right spiral groove track 14b as opposed to opening by the rotational force of the motor 20 to close the cup outlet and close the cup outlet. Connected to the closing detection switch (SW2) at the first point Up to stop the driving of the motor 20 and repeatedly performs a series of functions to return to the original state.
