Abstract
Dispensing apparatus is provided for simultaneously dispensing metered quantities of a plurality of materials into a common receptacle. Pump modules each containing a plurality of individual pump members are arranged in a rectangular pattern, between a base plate and a drive plate. The drive plate is raised and lowered, toward and away from the base plate, by a pair of drive screws. The plurality of individual pump members are thus simultaneously operated to dispense different materials into a common receptacle, at the same time.
Claims38
Dispensing apparatus, comprising:
- a frame;
- a bottom plate supported by the frame;
- a top plate;
- at least one slide support carried by said bottom plate so as to extend toward said top plate;
- at least one of said slide support supporting said top plate above said bottom plate;
- a generally rectangular drive plate slidably supported by said at least one slide support for movement toward and away from said bottom plate;
- a plurality of material supply vessels;
- a dispense head;
- a plurality of selectively operable valve means coupled to said dispense head;
- a plurality of pump means for pumping said material carried by said bottom plate and arranged on said bottom plate in a rectangular pattern, having inlets coupled to respective ones of said material supply vessels and outlets coupled through respective ones of said valve means to said dispense head, said pump means further having first ends coupled to said drive plate and second ends coupled to said bottom plate, said first and second ends movable with respect to each other so as to pump material through said pump means;
- and
- actuating means for moving said drive plate toward and away from said bottom plate so as to pump material through said pump means.
