4 Claims.
'I'his invention appertains to an improvement in automatic spraying machines, and has for an object to provide one of a comparatively simple, inexpensive, and eicient design and construction, to spray paint or the like onto an object, especially a dat surface, which is movable by an endless conveyor or the like relatively to the spray head or nozzle of the machine; the spray head or nozzle, itself, being movable relatively to the object and the conveyor, in order to completely coat the exposed surface, or surfaces, of the object automatically, without need for any manual control or operation, other than that required to start and stop the machine.
Another object of the invention has to do with the provision of a spray machine of this kind, wherein an electrically operated spray gun is mounted on a motor driven dolly, which is, in turn, mounted on a trackway for reverse directional movements thereon relatively to and transversely of the aforesaid conveyor, a reverse gearing being interposed between the motor and the drive connection with the dolly to change the direction of travel of the latter along the trackway, the reverse gearing being automatically operable when the dolly reaches its opposite limits of travel.
A further object of the invention lies in the provision of a spray apparatus as hereinbefore characterized, wherein an electric eye and a light source are cooperatively mounted on the dolly to have a common focal point to scan the surface, or surfaces, to be coated, during the relative travel of the dolly and the aforesaid conveyor, and thereby control the operation of the spray gun; the electric eye acting to close a circuit on the spray gun following the movement of the object into focus and to open the circuit when the latter moves out of focus, thus assuring of full coverage of the exposed area of the object and, at the same time, preventing waste of tl'il` coating material, or paint.
With these and other objects and advantages of equal importance in view, the invention resides in the certain new and useful combination, construction, and arrangement of parts and circuits, as will be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawings, in which:
Figure 1 is a front elevation, partly in section, a
of a practical embodiment of the spray apparatus or machine, in accordance with our invention;
Figure 2 is an enlarged, fragmentary, top plan view;
Figure 3 is an enlarged, fragmentary, vertical,
longitudinal section, taken through the line 3-3 on Figure 2, looking in the direction of the arrows;
Figure 4 is a front elevation of the electrically operated spray gun, per se;
Figure 5 is an elevational side view of the spray gun, taken at right angles to the elevational view of Figure 4;
Figure 6 is an enlarged, horizontal section, taken through the housing of the reverse gearing interposed between the motor and the drive connection with the dolly;
Figure 7 is a vertical, longitudinal section, taken through the line 'I'I on Figure 6, looking in the direction of the arrows; and,
Figure 8 is an enlarged, fragmentary, elevational view, partly in section, of an end of the trackway, showing one of the adjustable abutments or pins for actuating the control lever of the reverse gearing.
Referring to the drawings, wherein like characters of reference denote corresponding parts in the several views, the invention, as it is exemplii'led therein, is generally comprised in a horizontally travelling work conveyor; a trackway mounted transversely of and above the conveyor; a carriage or dolly supported for reverse directional movements on the trackway; a power drive mechanism mounted on the carriage or dolly for its operation; an electrically operated spray gun mounted on the carriage or dolly; means, also mounted on the carriage or dolly, for automatically controlling the operation of the spray gun; and other means, mounted in part on the carriage or dolly and in part by the framework of the trackway, for automatically controlling the directional movements of the carriage or dolly along the trackway.
The work conveyor is preferably in the form of an endless belt Il), mounted on rollers I2 (one only being shown in Figure 1), to convey objects, e. g., sheet materials, to be coated, i. e., painted, beneath the trackway I4; the latter is oi extremely simple construction and, as shown in Figures 1 and 2, is comprised of horizontally disposed, parallel rails I4', suitably supported in properly spaced relation above the conveyor I0; one of the rails at least is provided with vertically extending end portions I4", substantially as shown.
The carriage or dolly is embodied in a substantially rectangular platform I6, having journals I8 adjacent the opposite ends of its upper side to support axles 20, upon which grooved wheels 22 are keyed for rolling engagement with the rails I4' of the trackway I4. Secured on the platform I6 is an electric motor 24 which is coupled, at 26, to as reduction gearing 28 that, in turn, is coupled, air-ZB, to a reversing gearing 30. As best shown in Figures 6 and 7, the reversing gearing is housed within a casing having a shaft 32 journalled -in its end walls, with one end of the shaft extending outwardly for coupling to the power take-off shaft of the reduction gearing 28. Opening through the inner side wall of the reversing gearing casing, is a bearing 34 to support a power take-off shaft 36, disposed at right angles to the shaft 32, which shaft 86 carries a pulley 38 on its outer end and a bevel gear 48 on its inner end. Splined on the shaft 32 is a sleeve 42, having a pair of opposed bevel gears 44 mounted on its ends. Formed centrally on the sleeve 42 is a channel 46 to receive the forked inner end of an actuating lever 48, the outer end of which projects from the top wall of the casing 30 for its operation to shift the sleeve 42 in opposite directions on the shaft 32 t0 move the bevel gears 44 alternately into and out of mesh with the iixed bevel gear 40. The pulley 38 is connected by an endless belt 50 to a pulley 52, keyed on one of the axles 20, thus applying the power of the motor 24 to the carriage or dolly for its reversed directional movements along the trackway I4, at a proper speed as determined by the gearing and pulley ratio. The lever 48 is pivoted, as at 48', in ears formed at the opposite longer sides of a slot in the top wall of the gear casing 30, and carries lugs 48" on the inner sides of the arms of its inner forked end in engagement with the channel 46, on the sleeve 42, substantially as is shown in Figures 6 and 7.
For the purpose of reversing the direction of travel of the carriage or dolly, abutments 54 and 55 in the form of adjustable pins are provided and are mounted in the vertical members I 4, of the trackway I4, in the path of movement of the lever 48, so as to strike the outer end of the latter at the end of each movement of the carriage or dolly in opposite directions on the trackway; the lever, when struck, acting to shift the sleeve 42 and the bevel gears 44 relatively to the gear 40, causing the latter to rotate the take-off shaft 36 and the pulley 38, together with the pulley 52 and the axle 20 on which it is mounted, alternately in opposite directions, with the result that the carriage or dolly is positively driven likewise and at a uniform speed. The abutment pins 54 and 55 are screw threaded through the parts I4" and each carries a nut 56 to secure them in adjusted positions, substantially as shown in Figures 1 and 8.
A conventional form of electromagnetically operated spray head or gun 58 is carried on the lower end of a length of metal tube 60, depending through an opening, formed in the platform I6, and a substantially conical support 62, is secured on the under sideof the latter; a set screw 64 is carried by the support to permit of vertical adjustment of the tvie in setting the spray head or gun 58, at a selected spraying distance relatively to the work, supported on the conveyor I0. As best shown in Figures 4 and 5, the spray head or gun 58 is provided with a liquid inlet connection 66 for the coating material or paint and a second inlet connection 18 for a uid pressure supply, the connections 66 and 10 being adapted for attachment to lengths of flexible hose 68 and 12, respectively, lead to sources of supply` Mounted on the platform I6, adjacent the upper end of the supporting tube 60 for the spray head or gun 58, is an amplifier 14, having proper elec.- Y,
/s'pray head or trical connections, from its power output side,
leading to the operating solenoid 11 of the spray head or gun, and other proper electrical connections 18 leading to a photo-electric cell 18, also mounted on the platform and at one side of the amplifier and, consequently, at one side of the spray head or gun. The photo-electric cell 18 is carried by a bracket 82 and is adjustable thereon by means of a thumb-screw 82 to vary its angular relation with respect to a focal point on the work, which point is located in line with the vertical axis of the spray head or gun 58. Supported from the bracket 82, immediately below the photo-electric cell 18, is a light beam concentrating lens 80, which, together with the cell 18 is positioned above a glass panel 84, mounted in an opening in the platform I6. Rising from the platform I8, at the opposite side of the amplifier 14 and beyond the upper end of the supporting tube 60, is a bracket 86 to support an electric lamp 88 above a second glass panel 80, mounted in an opening in the platform; the lamp being set at an angle that its beam is directed onto the aforesaid focal point of the photo-electric cell 18. The lamp 88 is provided with electrical connections 82, leading to a suitable source of current, which may be the same source from which the motor 24 is supplied.
In operation, with the conveyor I0 provided with a suitable electric drive (not shown), the work is positioned thereon with reference to the 8 in a manner that the sprayingpperationgg bes 1a a. eleading edge 6r sideQLthLwnr'iat, in e re ative movement of the conve the carriage or dolly, the entire milgiEi-Fid top surfaces of the object or sheet will be uniformly coated. As the work moves with the conveyor Ill, the carriage or dolly moves crosswise thereof in reversed directions and continues so to do until the object or sheet is completely coated. With the starting motions of the conveyor l0 and the carriage or dolly, light from the lam 88 is reflected from the point onmlpmrme cell 18 sto troi 11 of th/spray head or gun 5s, p aiiit l 'rin es ed opera ive condition, and, thereafter, the spraylg gration is entirely automatic, until the work is comp e y coated. Witlr, the completion e spra g operation, the work passes from the focal point of the cell 'I8 and the lamiganhegction of the lighta beam from t atter ceases, rendering the cell 18 inoperative to supply er current to the amplifier 14 and', consequently, to the solenoid 11, which fle-energize cotingmaterial and fluid pressure from the he electric motor 24 is preferably of a variable speed type. or it will be operatively connected to the carriage or dolly through a variable speed drive system (not Shown), in order that the rate in speed of the carriage or dolly may be readily adjusted to conform to the speed of the conveyor I0. In this manner, a greater iiexibility in control of the thickness of the coating of the spray material on the object or sheet will be obtained. The amplifier-photoelectric cell system here employed is designed to have the sensitivity of the cell 18 to be greater when the spray head or gun 58 is not in operation and to decrease in sensitivity as soon as the latter is brought into play, in order that the head or gun will come into operation immediately upon its arrival over the leading edge or surface of the bevel gear 40.
object or work and will cutoil' likewise promptly upon d e passing of the latter out of the focal point the cell 18 and the lamp 88 thereon. In this way, all4 wastage of the coating material is avoided, without leaving any of the edges of the object or sheet uncoated. In the movements of the carriage or dolly along the trackway I4, when the limits thereof are reached in each direction. the gear shift lever 48 is engaged by the abutments or stop pins 54 and 55 and is moved to proper positions to alternately move the bevel gears 44 into and out of engagement with the An explosion-proof casing 94 is provided to enclose the amplifier 14, the photoelectric cell 18, and the electric lamp 88, and it may be extended to completely enclose the upper side of the platform I6, if desired, to afford protection to the drive mechanism. A cable 82 leads from the casing 94 for connection with a suitable source of electric current supply (not shown) to provide the necessary energy to the motor 24 and the lamp 88.
While in the foregoing we have described our invention in its preferred embodiment, it is to be understood that the words which we have used are words of description rather than of limitation, and that changes within the purview of the appended claims may be made, without departing from the true scope and spirit of our invention in its broader aspects.
