Abstract
A filled plastic bag may contain insulation. The bags are stacked in a loader. A pair of reciprocating arms rotate a bottom-most bag causing that bag to fall through an opening of a base. A conveyor receives the bag and moves it through a transverse knife and a longitudinal knife. Once the bottom of the bag is slit into quadrants, a pair of gripper wheels peel the bag off. The bag's contents fall into a hopper of a blower.
Claims15
A system for opening rectangular bags of non-powdered insulation material into a dispensing subsystem, the system comprising:
- a storage subsystem capable of holding one or more rectangular bags of a same first size in a vertical stack;
- a releasing subsystem capable of releasing a rectangular bag located at a bottom of the vertical stack (first bag) from the storage subsystem into a first conveyor subsystem;
- wherein the first conveyor subsystem is capable of transporting the first bag from the storage subsystem to a cutting subsystem;
- the cutting subsystem comprising a longitudinal stationary blade and a moving transverse blade;
- wherein the longitudinal stationary blade cuts one or more longitudinal slits in a bottom of the first bag in a longitudinal direction as the first bag travels through the cutting subsystem;
- wherein the moving transverse blade cuts a plurality of slits in the bottom of the first bag in a transverse direction as the first bag travels through the cutting subsystem;
- the transverse slits intersecting the longitudinal slits;
- a gripping subsystem comprising two gripping wheels capable of separating the first bag from the non-powdered insulation material housed within the first bag after the first bag is cut;
- and
- wherein the non-powdered insulation material falls from the gripping subsystem into the dispensing subsystem.
A system for opening rectangular bags of non-powdered insulation material into a dispensing subsystem means, the system comprising:
- a storage subsystem means functioning to hold one or more rectangular bags in a vertical stack;
- a releasing subsystem means functioning to release a rectangular bag located at a bottom of the storage subsystem means (first bag) from the storage subsystem means to a conveyor subsystem means;
- the conveyor subsystem means functioning to transport the first bag from the storage subsystem means to a cutting subsystem means;
- the cutting subsystem means functioning to cut slits forming a plurality of quadrants in a bottom of the first bag;
- said cutting subsystem means having a stationary blade means functioning to cut a longitudinal slice along the bottom of the bag and having a powered transverse blade means functioning to cut a plurality of transverse slices on the bottom of the bag;
- wherein said transverse slices intersect the longitudinal slice;
- a gripping subsystem means functioning to separate the first bag from the loose material housed within the first bag;
- and
- the dispensing subsystem means functioning to dispense the non-powdered insulation material in a controlled manner.
A process of opening a rectangular bag of non-powdered insulation material into a dispensing subsystem, the process comprising the steps of:
- storing one or more rectangular bags in a vertical stack within a storage subsystem;
- rotating a rectangular bag located at a bottom of the vertical stack (first bag) such that the first bag falls through a rectangular opening in a base plate;
- transporting the first bag from the storage subsystem to a cutting subsystem;
- cutting slits in two different directions in a bottom of the first bag via a stationary blade and a moving blade located within the cutting subsystem;
- providing said moving blade with a powered transverse motion actuator;
- cutting a plurality of transverse slits across at least one longitudinal slit by actuating said moving blade;
- separating the first bag from the non-powdered insulation material housed within the first bag by gripping the first bag between two wheels rotating in opposite directions;
- and
- receiving the non-powdered insulation material in the dispensing subsystem.
