  • Patent number: 9470368
    Abstract: A buffer unit is configured to store and transfer adhesive particulate to at least one adhesive melter. The buffer unit includes a buffer bin defining an interior space configured to hold a bulk supply of adhesive particulate with an agitator plate positioned within the housing at a non-horizontal orientation. A vibration generating mechanism is coupled to the agitator plate so that vibration is transmitted into the adhesive particulate to form a flow of fluidized adhesive particulate which flows toward at least one pump inlet. The buffer unit breaks up clumps of coalesced adhesive particulate to avoid clogging the pump inlet, while also ensuring that all adhesive particulate in the buffer bin can be removed at the pump inlet. Additionally, makeup air used by pumps to generate vacuum at the pump inlet does not need to be drawn through the entire bulk supply of adhesive particulate.

    Abstract: A machine for conditioning and dispensing loose fill insulation material, such as cellulosic insulation, fiber glass insulation and rock wool insulation. The machine includes a hopper, a conditioning chamber, an air lock and a blower for pneumatically dispensing the material. The conditioning chamber is equipped with three rotating shafts with helically arranged spikes which serve as conveyors as well as dispersers. A lower conveyor shaft moves the material toward the opening into the air lock, while the two uppermost conveyor shafts move the material in the opposite direction. Thus, the same assembly which conveys the material to the air lock also conditions the material. Moreover, the counter current flow pattern churns or agitates the insulation material while the individual spikes disperse it. A single motor drives the rotation of the conveyor shafts and the rotation of the vanes in the air lock.

    Abstract: An apparatus for depositing loose materials, such as insulation or fireproofing in worksite areas, may be used for depositing a single or premixed loose material. Alternatively, the apparatus may be used both for combining two constituent loose materials to form a composite loose material and for depositing the composite loose material in a worksite area. The apparatus includes a separate hopper or bin for each of the constituent loose materials. Each hopper is operatively connected to a single loose material combining channel for supplying their respective constituent loose material for forming the composite loose material immediately before it is deposited in the worksite area. A single motor is used for supplying both constituent loose materials to the combining channel. The ratio of constituent loose materials in the composite loose material may be changed by replacing an easily accessible gear used in driving an auger for extracting the constituent loose material from one of the hoppers.

A metal axial spacer is preferably next to the plate, but only within the innermost radius of chambers and with a sizable wall thickness. The body is preferably a feed-bowl type, with chambers formed as generally U-shaped pockets. A gunite machine using the polymeric feed structure also has a hopper, delivery tube, support and rotation of the feed structure, compressed-air for expelling the particulate material from the chambers into the tube, and provision for transporting the hopper, tube, body, and other apparatus. Chambers are selectively sealed to the expelling device and delivery tube.

  • Patent number: 5590984
    Abstract: In a method and a system for installing loose insulation, loose wool is transported, in compacted state and packed in e.g. filled bags (12), to the site where the insulation operation is to be performed and where loose wool (11) received from the bags is mechanically fluffed, and where the fluffed loose wool is transported by blowing it through a hose (15) to the location where it is to be placed; and the loose wool supplied through the hose (15) is spread on said location in the desired configuration. The novelty of the invention resides in that the bags (12) containing loose wool first are so arranged as to be able, successively and in a controlled manner, to discharge the compacted loose wool contained therein for automatic fluffing and onward blowing through the hose, whereupon from the location where the spreading of loose wool takes place, the discharge of compacted loose wool from the bags is remote-controlled in connection with the spreading, whereby the method can be carried out by a single operator.

  • Patent number: 5403128
    Abstract: A fully integrated insulation spraying system with an insulation spraying subsystem for spraying wet or dry insulation and a fiber recovery subsystem for recycling waste insulation fibers and reintegrating them into the spraying process for more efficient and ecologically sound use of the insulation material. The insulation spraying subsystem includes a hopper with a rotary conveyor that conditions the fiber insulation and carries it into a standby chamber which is connected an airlock that introduces the fibers into a moving airstream. The airstream carries the fibers to the spraying head where moisture is added to promote adhesion of the insulation. A pneumatically powered insulation shaver is provided for smoothing the insulation after it is applied.

  • Patent number: 5114281
    Abstract: A machine for blowing loose thermal insulation into cavities in the walls, ceilings, and floors of buildings is contained within a smooth box-like housing that is easily moved about within a house on its own wheels and is easily transported to and from a job site. The housing encloses an equipment cavity and has a hopper located above the equipment cavity, but the hopper, into which the loose insulation is placed, is octagonal so that corner channels exist within the housing between the sides of the hopper and the corners of the housing. The equipment cavity at the bottom of the housing contains a motor which rotates an agitating wheel in the hopper, and that wheel has flexible tips that sweep the loose insulation over the floor of the hopper and into a feed hole in that floor. A grate extends through the hopper above the wheel to prevent access to the wheel in the bottom of the hopper.

  • Patent number: 4978252
    Abstract: A feeder apparatus is provided for delivery of insulation material or the like using pressurized air, particularly where such material is relatively light and fluffy and/or delivered at a low rate. The feeder apparatus includes a hopper and a chute. The hopper receives the material, which is to be carried using the pressurized air. A chute housing a pair of tine assemblies receives the material from the hopper and is used in carrying the material to an inlet. The inlet is formed by first and second adjusting assemblies, which are located on opposite sides of the chute. The user is able to provide a desired size inlet by rotating crank handles of the two adjusting assemblies to cause linear movement of adjustable plates. Material passing from the inlet is received by a rotary pocket feeder having a number of vanes. Pressurized air is also delivered to the rotary pocket feeder. The pressurized air carries the material through an outlet formed in the pocket feeder for delivery to a predetermined site.
