Abstract
An improved dry mix dispensing apparatus and method for controllably dispensing materials from bulk storage bags are disclosed. A support structure is provided for elevating loaded bulk bags over a collector and discharge means that controllably empties the contents of the bag, one batch at a time, as needed, into an underlying batch mixer. The collector only processes that material currently being dispensed, and the bag continues to store the bulk material until actually dispensed through the collector. The dispensing apparatus is rapidly collapsible in the vertical and lateral directions for ease of transport and movement about the construction site.
Claims20
A portable dispenser for changing a batch mixer with powdered materials of the type carried by a flexible storage container containing multiple charges of such materials, said storage container having downwardly depending walls defining a lower outlet port, comprising:
- (a) a support frame sized and configured for resting on a support surface and to enable a portable batch mixer to be aligned at a receiving station to one side thereof;
- (b) a collector suitable for continuously receiving materials from a flexible bulk storage container, sized to retainably hold only a portion of the materials carried by said storage container;
- (c) means for supporting said collector in fixed cantilevered manner to one side of said support frame and generally overlying said receiving station;
- (d) container support means operatively connected to said support frame for supporting the flexible storage container in cantilevered manner in operative unattached overlying juxtaposition with said collector such that said materials released through said outlet port of said flexible container are immediately collected and retained by said collector;
- and such that said container walls, in combination with said collector, contain said material leaving said outlet port to said collector;
- and
- (e) means operatively connected with said collector for controllably discharging said retained materials from said collector to the batch mixer at said receiving station.
A portable dispenser for delivering premixed dry mortar-blend materials carried by a flexible bulk storage bag of the type having an outlet chute and containing multiple batch charges of said materials, to the inlet port of a batch mixer at a receiving station, comprising:
- (a) a collector having an inlet port and an outlet port and configured to continuously receive said materials from the flexible storage bag through its inlet port and to direct such materials toward its outlet port, said collector being sized to retainably hold only a portion of the materials carried by said storage bag;
- (b) means for supporting said collector above said receiving station and for supporting said storage bag in operative overlying but unattached relationship with said collector, with the outlet chute of said bag being aligned with and addressing said collector such that flow of said materials exiting from said bag are retainably redirected by said collector;
- and
- (c) discharge means operatively connected with the outlet port of said collector for controllably discharging said materials from said collector therethrough and toward the inlet port of a batch mixer at said receiving station;
- wherein said discharge means causes said materials to leave said bag in real time in direct proportion to the amount of said materials discharged by said discharge means.
A method of dispensing materials at a construction site from a flexible bulk storage bag of the type having an outlet discharge chute and containing a plurality of batch charges of such materials, comprising the steps of:
- (a) supporting a collector having a controllable discharge means, above a receiving station for a batch mixer;
- (b) hanging the bulk storage bag in elevated manner over said collector;
- (c) operatively fixing the height of the bag such that its outlet discharge chute operatively addresses and is juxtapositioned over but unattached to the collector;
- (d) opening the outlet discharge chute of the bag, enabling its contents to flow by gravity into said collector;
- (e) controllably emptying said materials from said storage bag, through said collector and discharge means, one batch at a time;
- and
- (f) directing by gravity the emptied materials, from said collector to said receiving station.
