Definitions

  • the object therefore of this invention is to disclose a dry method, as opposed to a wet method, of disposing of the excess paint in a spray booth.
  • Another object of the invention is to provide improved means for practicing the method.
  • a further object of the invention is to provide a paint spray booth, which has a comparatively thin wall of highly absorbent, readily disposable material.
  • Another object of the invention is to provide a paint spray booth which has a substantially vertical, maximal: sively moveable, thin wall of highly absorbent, normally dry, non-woven, fabric material, positioned to absorb and trap all excess spray paint.
  • Another object of the invention is to provide a paint spray booth having a thin wall of highly absorbent material of the character indicated, with means for main taining a fresh supply of such material, and means for facilitating the easy disposal of used portions of such material.
  • Fig. l is a perspective view of a paint spray booth embodying the invention.
  • Fig. 2 is an enlarged perspective view of the booth illustrated in Fig. l, with parts broken away to show the relation of other parts.
  • Fig. 3 is a side elevational view of the device illustrated in Fig. 1 with parts broken away and parts in -sectin.
  • Fig. 4 is a section taken substantially on the line 4-4 of Fig. 3.
  • the reference character 7 indicates, in general, the paint spray booth, which. is preferably made in three sections, designated by the reference characters 8, 9 and 10.
  • the section 8 consists of a pair of wings 11 and 12 and a canopy 13.
  • the section 8 serves as a protective stall for the operator 14, who is using a paint spray gun 15, to paint an object 16.
  • the sections 8, 9 and 10 are all preferably made of light sheet metal material and are fabricated and secured together by any suitable means.
  • the section 9 has a top 17 and side walls 18 and 19, which serve as a housing for and means to support, the upper roll 20, on which is stored the material, from which the fabric curtain 21 is formed.
  • the curtain 21 extends downwardly from the roll 20, to form the front wall of the section 9.
  • the curtain 21 passes over an idler roll 22, and on to a collector roll 23, which is constructed and driven as hereinafter described.
  • the section 9 is provided with hinged panels 24 and 25, so that access may be had to the rolls 20 and 23, for
  • the curtain wall 21, is preferably backed up with an welded to angle members 27 and 28 (Fig. 3), which serve to re-inforce and support the walls of the section 9.
  • the screen 26 is intended to re-inforce the material of the curtain 21, so that the curtain 21 may withstand the blast from the spray gun 15, and the current of air, which passes through the curtain 21, and may resist-the pressure of any object which might be forced against it.
  • the roll 20 is carried on an axle 29, the ends of which ride in channel members 30, secured to the inside of the walls 18 and 19.
  • the roll 22 is similarly supported.
  • the rolls 20 and 22 are readily installed, by causing the ends of their axles to be received in the channels 30.
  • hub 31 is splined on the shaft 35, so that it may slide to the left, against .the pressure of the spring 37, and
  • the hub 31 is provided with keys 38, which engage slots 39, formed in the ends of the tubular member 23A, so that the latter may be rotated by the drive shaft 35.
  • the hub 32 and end plate 34 rotate on a stub shaft 40, which is welded or otherwise secured, as at 41, to a backing plate 42, which is secured to the inner face of the wall 19.
  • a roller bearing 43 is preferably interposed between the stub shaft 40 and the hub 32.
  • the sprocket 36 which rotates the shaft 35 is driven by a chain 44, which in turn is driven by a smaller sprocket 45, which is driven by an electric motor 46, through a suitable gear reduction, not shown.
  • the drive motor 46 is preferably manually controlled, by means of a switch within easy reach of the operator 14, so that portions of the curtain material 21 may be intermittently advanced from the roll 20 to the collector roll 23.
  • the sprockets 36 and. 45 and thechain 44 are all covered by means of a cover..47, which is secured by any suitable means, to the outside of the wall 18.
  • the motor 46 andi'ts .gear reduction are housed in the bottom of the section 10.
  • the interior of the section 10, communicates at the top with a stack 48, in which ist-mounted an exhaust fan, not shown, which is driven by'means: ofv an electric motor 49.
  • the exhaust fan draws a-continuous stream of fresh airthrough the three sections 8, 9 and 10, and through the fabric curtain 2'1, and out the stack 48, as indicated by the arrows in Fig. 3:
  • The'curtain 21 preferably consists of azpre-determined length, of one hundred percent, nonwoven, cotton fibres, having a high factor of absorbency, which fibers are-calendered, or pressed, to a layer thickness of approximately one sixty-fourth of an inch, to provide a normally dry, smooth surface, without nap;
  • non-woven fabrics aremats of fibers held together with a bonding material, or by the action of. thermo-plastic and thermosetting resins, mixed in with the fibers. No yarns or conventional weaving equipment is used.
  • Non-woven, or bonded fiber fabrics consist of fibers adhesively bonded to one another.
  • the fibers are bonded together with heat, pressure and/ or vacuum-subjected to various forms of applications, to insure uniform dispersion of' thebonding agents.
  • Bonded fiber fabrics are usually produced on conventional carding equipment as'the basis for the web..
  • Thefibers'in the carded Web lienearly parallel, giving greater strength in the Warp Wise direction.
  • the fabric may also be produced on a garnetting machine. Bonding is done by a chemo-thermic process, under extremely-high heat, pressure and/or vacuum.
  • the non-woven clothreferred toin this application is a blend offibers, which will give maximum absorbency and is treatedso that it will have a smooth surface without nap,.with resins, which will-add a maximum degree of bonding and tensile strength, and yet will ofier little resistance to thepassage of'air therethrough.
  • the fabric material is preferably flame-proofed, with any suitable chemical composition.
  • Thematerial so described has a comparatively-high tensile'strength, offers little, if any, resistance to the passage of air there-through, and becauserof itshigh factor of absorbency, will catch, hold and absorb, any and all excess paint spray, which may contact itduringa paint spray operation. This material when loaded with excess paint spray, is readily disposable.
  • The'usedsections are continuously rolled onto the collector roll 23, which when filled is removed and dis posed of.
  • the method of trapping and disposing of paint overspray which consists of providing a booth-like structure havingatleast one moveable wall formed of. a thin.curtain of normally dry, highly absorbent, non-woven, cotton fabric material of sufii'cient tensil'estrength to permit it to be pulled from a rotating support, positioning an object to be paint sprayed in close proximity to said curtain, passing a current of air about said object and through: and around said curtainand' while said air-is in motion; directing a paint spray toward said object, and thencausing' said curtain to be removed from its'said' original wall position.
  • A.curtain as defined inclaim 2 including rotating. means'. for suspending said curtain in said booth and means for pulling sections of said-curtain into and out ofia predetermined: position with respectto said booth;
  • a paint spray booth having a moveable wall; consisting of a continuous layer of normally dry, highly absorbenhfiame proofed,.non woven, cotton fabric materiaLapproximately one sixty-fourth of aninch in thickness', and pressed toa napless, smooth finish and having suflicient tensile. strength. to support large paint laden sections. thereof, means for adjustably supporting saidlayer, means for directinga current of air through: and
