Abstract
The packaging machine is provided with a dumper shaft which includes material receiving chambers which can be adjusted in size to receive and measure varying amounts of material. Each material receiving means is made up of a pair of coaxial discs and radiating plates between the discs, the discs being held in place by locking collars. Outlet nozzles from the hopper above the dumper shaft are disposed to empty into a respective chamber while being disposed within the plane of the chamber. As the dumper shaft is rotated, the hopper and the outlets are raised to permit rotation. The upper edge of each plate has a lip or ledge directed in the direction of rotation of the dumper shaft to retain the material during rotation.
Claims21
A packaging machine comprising
- a hopper for receiving a supply of flowable material, said hopper having a plurality of outlet nozzles in a base thereof for outflow of a plurality of streams of the flowable material;
- a rotatable dumper shaft below said hopper, said dumper shaft having a plurality of flow measuring means thereon, each said measuring means being disposed below a respective hopper outlet nozzle and including a pair of discs adjustably mounted on said shaft in coaxial relation for longitudinal movement along said shaft and a plurality of plates between said discs and radially of said shaft to define a plurality of material receiving chambers circumferentially disposed about said shaft, each said chamber being of adjustable size to receive varying amounts of material from a respective outlet nozzle;
- a plurality of guide tubes, each said tube being aligned with a respective measuring means to guide a measured amount of material therethrough;
- means for moving a pair of continuous sheets over said guide tubes;
- means for sealing the continuous sheets to each other between and alongside said guide tubes;
- and
- a pair of rotatable seal bars below said guide tubes for sealing the sheets to each other transversely of said guide tubes to define sequentially spaced packets containing measured amounts of the material.
A dumper shaft for a packaging machine for dispensing packets containing measured amounts of material, said dumper shaft having a plurality of longitudinally spaced apart flow measuring means to receive a flow of material, each said measurng means including a pair of discs removably mounted on said shaft in coaxial relation, a plurality of plates between said discs radially of said shaft to define a plurality of material receiving chambers circumferentially disposed about said shaft and locking collars for securing said discs on said shaft.
In a packaging machine;
- a hopper for receiving a supply of flowable material, said hopper having a plurality of outlet nozzles in a base thereof for outflow of a plurality of streams of the flowable material;
- a rotatable dumper shaft below said hopper, said dumper shaft having a plurality of flow measuring means thereon, each said measuring means being disposed below a respective hopper outlet nozzle and including a plurality of material receiving chambers circumferentially disposed about said shaft to receive material from a respective outlet nozzle;
- and
- means for reciprocally moving said hopper vertically relative to said dumper shaft, wherein said outlet nozzles are disposed to move between a position in the circumferential plane of said plates of said measuring means and a position spaced therefrom.
A packaging machine comprising
- a hopper for receiving a supply of flowable material, said hopper having a plurality of outlet nozzles in a base thereof for outflow of a plurality of streams of the flowable material;
- a rotatable dumper shaft below said hopper, said dumper shaft having a plurality of longitudinally spaced apart flow measuring means thereon, each said measuring means being disposed below a respective hopper outlet nozzle and including a pair of discs adjustably mounted on said shaft in coaxial relation for longitudinal movement along said shaft and a plurality of plates between said discs and radially of said shaft to define a plurality of material receiving chambers circumferentially disposed about said shaft, each said chamber being of adjustable size to receive varying amounts of material from a respective outlet nozzle;
- a plurality of guide tubes, each said tube having a funnel portion at an upper end projecting into the plane of a respective measuring means and aligned with a respective measuring means to receive a measured amount of material;
- and
- means for receiving individually dispensed charges of material from said guide tubes to define sequentially spaced packets containing measured amounts of the material.
A packaging machine comprising
- a hopper for receiving a supply of flowable material, said hopper having a plurality of outlet nozzles in a base thereof for outflow of a plurality of streams of the flowable material;
- a rotatable dumper shaft below said hopper, said dumper shaft having a plurality of discs adjustably mounted on said shaft in coaxial relation for longitudinal movement along said shaft and a plurality of plates between said discs and radially of said shaft to define a plurality of material receiving chambers circumferentially disposed about said shaft, each said chamber being of adjustable size to receive varying amounts of material from a respective outlet nozzle;
- a plurality of guide tubes, each said tube being aligned with a respective measuring means to guide a measured amount of material therethrough;
- means for moving a pair of continuous sheets over said guide tubes;
- means for sealing the continuous sheets to each other between and alongside said guide tubes;
- and
- a pair of rotatable seal bars below said guide tubes for sealing the sheets to each other transversely of said guide tubes to define sequentially spaced packets containing measured amounts of the material.
