Abstract
Dispensing apparatus includes canisters mounted on a turntable, the canisters including dispense pumps and valves. Actuators for operating the dispense pumps and valves are located on a service door mounted alongside the turntable. The dispense apparatus is mounted on modular framework to improve serviceability of the components employed.
Claims29
Dispensing apparatus for dispensing a plurality of pulverulent materials, comprising:
- a plurality of canisters for storing materials to be dispensed;
- a dispensing station whereat the materials are dispensed;
- a plurality of metering pumps, associated with respective ones of said plurality of canisters for receiving materials therefrom, the metering pumps including pump operators for dispensing preselected amount of materials withdrawn from the canisters;
- a movable platform for supporting the plurality of canisters and for presenting preselected ones of the plurality of canisters to the dispensing station;
- a frame supporting the platform;
- a door at the dispensing station, hingedly supported by the frame;
- pump actuator means carried on the door, for engaging the pump operators and for actuating the pump operators to selectively withdraw and dispense preselected amounts of materials from the canisters.

Apparatus for dispensing flowable materials, comprising:
- a plurality of canisters for holding the flowable materials,
- a plurality of metering pumps for withdrawing preselected quantities of materials from the canisters and for discharging the materials, and
- a plurality of valves associated with the metering pumps, for controlling the flow of materials discharged from the metering pumps;
- a workstation adjacent the canisters where materials are dispensed;
- a housing at least partly surrounding the canisters;
- turntable means for carrying the metering pumps and valves so as to present a preselected canister to the workstation, at least a portion of the turntable being made of magnetic material;
- drive means for moving the turntable to bring a selected canister to the workstation;
- and
- braking means adjacent the turntable to stop movement of the turntable to align the selected canister at the workstation, the braking means comprising an electromagnet supported by the housing adjacent the turntable to magnetically attract the turntable so as to engage the turntable.
