Abstract

A machine for distributing material from a package of compressed loosefill insulation material is provided. The machine includes a chute having an inlet end and an outlet end. The inlet end is configured to receive compressed loosefill insulation material. A lower unit has a shredding chamber configured to receive the compressed loosefill insulation material from the outlet end of the chute. The shredding chamber includes a plurality of shredders configured to condition the loosefill insulation material. The shredders include a shredder shaft and a plurality of vane assemblies. The vane assemblies are oriented such that adjacent vane assemblies are offset from each other by an angle of about 45° to about 75°. A discharge mechanism receives the loosefill insulation material exiting the shredding chamber and distributes the loosefill insulation material into an airstream and a blower is configured to provide the airstream flowing through the discharge mechanism.

First claim

What is claimed is:

1. A machine for distributing loosefill insulation material from a package of compressed loosefill insulation material, the machine comprising:
a chute having an inlet end and an outlet end, the inlet end configured to receive compressed loosefill insulation material; and
a lower unit having:
a front panel;
a back panel opposing the front panel;
a left side panel;
a right side panel opposing the left side panel;
a shredding chamber enclosed by the front, back, left side and right side panels and configured to receive the compressed loosefill insulation material from the outlet end of the chute, the shredding chamber including a plurality of shredders configured to shred, pick apart and condition the loosefill insulation material;
an agitator;
a discharge mechanism mounted to receive the conditioned loosefill insulation material exiting the shredding chamber, the discharge mechanism configured to distribute the conditioned loosefill insulation material into an airstream;
a blower configured to provide the airstream flowing through the discharge mechanism; and
a removable front access assembly configured to cover a portion of the front panel of the lower unit, the removable front access assembly further configured for removal from the lower unit;
wherein the removable front access assembly includes a framework having an inlet assembly mounted therein, the inlet assembly including a screen adjacent a filter;
wherein a combination of the screen and the filter is configured as an air inlet; and

wherein removal of the removable front access assembly further makes the filter accessible for inspection, cleaning, and replacement, and makes the plurality of shredders, the agitator, and the discharge mechanism within the lower unit visible and accessible for inspection, replacement, and repair.

2. The machine of claim 1 , wherein with the removable front access assembly removed from the lower unit, the plurality of shredders and the agitator are visible.

3. The machine of claim 1 , wherein with the removable front access assembly removed from the lower unit, the blower is also visible and accessible for inspection, replacement, and repair.

4. The machine of claim 1 , wherein the removable front access assembly includes a control panel configured to direct operating characteristics of the machine.

5. The machine of claim 1 , wherein the removable front access assembly includes a display configured to visually show operating characteristics of the machine.

6. The machine of claim 1 , wherein the removable front access assembly includes a first aperture configured to receive a machine outlet.

7. The machine of claim 1 , wherein the removable front access assembly includes a second aperture configured to receive an electrical power cord connector.

8. The machine of claim 1 , wherein the removable front access assembly includes the inlet assembly configured to allow air exterior to the machine to enter and flow through the machine.

9. A machine for distributing loosefill insulation material from a package of compressed loosefill insulation material, the machine comprising:
a chute having an inlet end and an outlet end, the inlet end configured to receive compressed loosefill insulation material; and
a lower unit having:
a front panel;
a plurality of shredders configured to shred, pick apart and condition the loosefill insulation material;
a discharge mechanism mounted to receive the conditioned loosefill insulation material exiting the plurality of shredders, the discharge mechanism configured to distribute the conditioned loosefill insulation material into an airstream;
a blower configured to provide the airstream flowing through the discharge mechanism, the blower including a blower motor configured for variability in a rotational speed of the blower to provide an airstream, the airstream configured for removing stray fibers from an environment within which the machine for distributing loosefill insulation material is operating; and
a removable front access assembly configured to cover a portion of the front panel of the lower unit, the removable front access assembly further configured for removal from the lower unit;
wherein the removable front access assembly includes a framework having an inlet assembly mounted therein, the inlet assembly including a screen adjacent a filter;
wherein a combination of the screen and the filter is configured as an air inlet; and
wherein removal of the removable front access assembly further makes the filter accessible for inspection, cleaning, and replacement, and makes the plurality of shredders, and the discharge mechanism within the lower unit visible and accessible for inspection, replacement, and repair.

10. The machine of claim 9 , wherein the blower motor is configured for pulse width modulation control.

11. The machine of claim 9 , wherein the blower motor is configured for 120 volt alternating current (A.C.) operation.

12. The machine of claim 9 , wherein the blower motor requires a maximum current of 11.0 amps.

13. The machine of claim 9 , wherein the blower motor has a maximum rotational speed in a range of about 30,000 revolutions per minute to about 40,000 revolutions per minute.
