Airless adhesive spray guns are innovative devices that allow the spraying of adhesive without the “fog” overspray caused by the use of air-atomized spray guns. Airless spray guns result in far less fog, saving on total adhesive use. Further, these devices provide a safer, cleaner work environment. Further, the use of airless sprayed adhesive unexpectedly provides better adhesion as well.
Such spray guns operate by atomizing adhesive through a nozzle. Because of the shearing and other forces applied to the adhesive passing through the nozzle, the nozzle can easily and quickly become fouled with use. This fouling causes it to lose effectiveness and eventually clog. Clogging and general fouling is especially noticeable when use is stopped. This includes, for example, taking a break to re-fill an adhesive source, during rest, while replacing material to be sprayed with the adhesive, during lunch breaks, and at the end of the work day, among other times. The time off of use allows the adhesive left in and on the spray nozzle to harden and clog or otherwise interfere with flow through the nozzle. Typically, this clogging/fouling problem is addressed by manually scraping or otherwise removing the hardened adhesive.
Therefore, what is needed is a system that may limit adhesive buildup on the nozzle of the airless adhesive spray gun.
The subject matter of this application may involve, in some cases, interrelated products, alternative solutions to a particular problem, and/or a plurality of different uses of a single system or article.
In one aspect, a holster for holding a spray gun is provided. The holster is formed of a reservoir body. The reservoir body defines a chamber in which at least a portion of the spray gun can be received. This chamber is configured to be substantially fluid-tight to hold fluid within it without leakage. Two uprights may extend upward from a front face of the reservoir body. These uprights may serve to stabilize the spray gun when held in the holster. Further, a cross bar may extend from a rear of the reservoir body. The cross bar is configured such that a hook of the spray gun can be hooked to the cross bar. A connecting structure such as a flange may extend from the reservoir body to allow the holster to be connected to a wall or other support.
In another aspect, a spray gun holster system is provided. The holster system has a reservoir body. The reservoir body defines a chamber in which at least a portion of the spray gun can be received. This chamber is configured to be substantially fluid-tight to hold fluid within it without leakage. A connecting structure such as a flange may extend from the reservoir body to allow the holster to be connected to a wall or other support. An airless adhesive spray gun is positioned to be resting in the chamber, with at least a nozzle positioned within the chamber. Also within the chamber is a quantity of fluid, in which a nozzle of the spray gun is submerged.
The detailed description set forth below in connection with the appended drawings is intended as a description of presently preferred embodiments of the invention and does not represent the only forms in which the present invention may be constructed and/or utilized. The description sets forth the functions and the sequence of steps for constructing and operating the invention in connection with the illustrated embodiments.
Generally, the present invention concerns a holster for a spray gun. The holster may have a reservoir forming a cavity in which a forward portion of a spray gun, including the nozzle, may be placed. Fluid may be within the reservoir cavity to prevent a clogging and drying of adhesive or other chemicals on the nozzle of the spray gun.
The present invention provides a holster for an adhesive spray gun. Most embodiments of the holster may be designed for airless atomized adhesive spray guns, but the holster may also be used for air atomized adhesive spray guns, or indeed any fluid spray guns, in varying embodiments. The holster includes a reservoir having a liquid therein to prevent a drying of the adhesive (or other material sprayed through the nozzle) leftover in and on the nozzle. This liquid in the reservoir chamber may also help remove and/or dissolve adhesive on the nozzle. This reservoir may have a single chamber for a one-component or multi-component gun, or may have more than one chamber for a multi-component gun. For example, for a two-component spray gun (having two separate spray nozzles) there may be two chambers in the holster reservoir body.
In one embodiment, each chamber may be separated from the other and may contain a liquid placed therein. In another embodiment, the chambers may be separate from each other but for an opening in the separator allowing fluid interchange between the two chambers. In one embodiment, the liquid may be the same in each chamber. In another embodiment, the liquid may be different and may be specific to the material of the nozzle of the multi-component spray gun (that is to say, the material that is sprayed through each nozzle). The specific fluid placed in each chamber may be used to minimize adhesion and/or dissolve the material (an adhesive on a first nozzle and an adhesive activator on a second nozzle, for example) on each nozzle.
Typically, the holster is formed of stainless steel. However, it should be understood that any material may be used that is capable of holding the liquid in the reservoir and also capable of supporting the weight of the adhesive spray gun with minimal or no deformation. Such materials may include, but are not limited to: various metals and alloys, rigid plastics, composite materials, and the like.
The liquid stored in the reservoir may be any liquid capable of keeping the material in and on the nozzle (which is the material sprayed through the nozzle when in use) from drying out or otherwise hardening or thickening. In some further embodiments, the fluid may at least partially dissolve or break down this material (adhesive and activator, for example). In still a further embodiment, the fluid may be a water-based surfactant. Examples of which the liquid may be selected from include, but are not limited to: Water (preferably soft water or deionized water), Polyethoxylated tallow amines; Soaps of fatty acids such as water soluble tallates, laurates; Alkoxylated alcohols; Ethoxlated alcohols such as lauryl alcohol, decyl alcohol, C12-C18 alcohols; Ethoxylated phenols such as decyl phenol, dinonyl phenol, dodecyl phenol; Ethoxylated fatty acids such as laurate, stearate, oleate, tallate; Ethoxylated fatty amines such as tallow amine, tallow diamine, hydrogenated tallow amine, oleyl amine, stearyl amine, coco amine, coconut amine; Ethoxylated glycerides such as coconut glyceride, castor oil, hydrogenated castor oil; Phosphate esters based on various alcohols and phenols; Polyethylene glycolated esters; Polyoxyalkylene glycol ether; Sulfated alcohols; Sulfonated alcohols; Sulfonated castor oil; Alkyl carboxylates such as water soluble stearates, i.e. sodium stearate; Anionic surfactants such as Sodium Lauryl Sulfate, Sodium Lauryl Ether Sulfate; Anionic detergents such as alkyl sulfates, alkyl sulfonates, alkyl benzene sulfonates; Cationic detergents such as quaternary ammonium salts, fatty alcohols such as Lauryl Alcohol, Decyl Alcohol, C12-C18 alcohols; Nonionic detergents such as those based on polyoxyethylene; and Amphoteric surfactants such as imino acetates and imino propionates such as sodium octyliminodipropionate, among others.
Turning to the figures generally, particular embodiments of the spray gun holster are shown. These embodiments show the holster having a reservoir 10 that is attachable to a wall or other surface by at least one flange 11, 13. However, it should be understood that the holster may be positioned anywhere, and connected to a supporting structure in any manner. In one embodiment, the flange 11, 13 may swivel about a hinge relative to the reservoir body to provide flexibility in mounting location and surface. Two uprights 14 may protrude upward from the base reservoir 10 on the front of the holster to provide balance to the gun. Further, in some embodiments a cross bar 15 may extend upwards from a rear of the holster. In this embodiment, the spray gun may be hung on the cross bar 15 because many spray guns have a hanging hook on their top (See
In some embodiments, mounting flanges 11, 13 extend away from the reservoir to provide a spacing between the reservoir and a wall, so that the rear of the reservoir is not flush with the wall. A drain 22 may be positioned on an underside of the reservoir body 10 to allow draining of the liquid 21 within the chamber 16. In use, the liquid 21 is filled to a level within the chamber 16 sufficient to cover the nozzle when the spray gun 41 is positioned in the holster with the nozzle in the reservoir chamber 16. The spray gun can be placed in the holster when not being used and, when ready, can be removed for spraying.
