Abstract: A dispenser for compound-containing containers includes a cassette for a container; at least one push rod displaceable relative to the cassette; a motor for moving the at least one push rod; a main switch for generating a control signal in response to actuation of the main switch; a control unit for controlling the motor; and a sensor configured to detect the moving of the push rod which is electronically connected to the control unit. The control unit is configured to store the dispensed volume of the compound and provide a feedback to the user once the dispensed volume of the compound reaches a defined value, and the user gets informed as soon as the cassette should be checked. Based on saved information of the dispensed volume of the compound, the user can be informed if a specified volume is reached and a check of the cassette is recommended.

Abstract: A dispenser for compound-containing containers includes a receiving chamber for a container; at least one push rod displaceable relative to the receiving chamber; a motor for moving the at least one push rod; a control unit for controlling the motor; a main switch; an operation selection switch for setting a selected amount of the compound to be dispensed in one application run; and a sensor configured to detect movement of the push rod. The control unit is configured to store a missing amount of the compound when one application run is interrupted. The dispenser dispenses the missing amount of the compound when the main switch is actuated for finishing the interrupted application. If an application run gets interrupted, for example due to empty battery, the missing amount of the compound is dispensed instead of the preselected amount. This function allows the application to proceed without additional chemical or compound wastage.

Abstract: A dispenser for compound-containing containers includes a receiving chamber for a container; at least one push rod displaceable relative to the receiving chamber; a motor for moving the at least one push rod; a control unit for controlling the motor; a main switch for activating the motor; an operation selection switch for switching between different operation modes; and a first sensor configured to detect a position or movement of the push rod. The operation selection switch is configured to select an amount of the compound to be dispensed in one application run. The dispenser will warn the user once the remaining amount of the compound in the container is less than the needed amount for next application, so that the user will notice the compound shortage and prepare an additional container before starting the next application. Accordingly, rework of cured chemical compounds will be avoided.
