12 Claims.
This invention relates to paint spraying machines or devices and more particularly to an improved automatic spraying machine adapted to perform a variety of spraying operations.
' Spraying installations having manually controlled stationary spray guns and conveyor for moving the work past such guns have been successfully used on large pieces such as automobile bodies, structural steel beams, large panels, and the like. However, installations of this character cannot be used for painting small pieces, of odd shapes, such as various frames, bent pieces of molding, and the like, without prohibitivelylarge waste of paint, space, and time. Therefore, spraying of suchsmall pieces has been done by hand with resulting inefllciency, waste of time, material, and factory space. Such hand operations are also injurious to the'health of the operators and give low volume of production.
One of the objects of the present invention is to provide an improved automatic paint spray-- sumed to look in the direction of ing machine which can perform spraying operations on a variety of workpieces which heretofore had to be sprayed by hand.
Another object of the invention is to provide an improved automatic spraying machine which can be used for spraying such workpieces as bent pieces of molding, automobile window frames, and the like, and is adapted to spray the paint only over the surface of the workpiece and not on the conveyor, thereby eliminating the excessive waste of paint by preventing wasteful spray-- ing of paint through the openings in the workpieces onto conveyor surfaces.
A further object of the invention is to provide an improved spraying machine which is substantially continuous and automatic in its operation and can be served by one operator only and yet have a high productivity and give uniform coats of paint onthe workpieces.
A still further object of the invention is to prothe following description and appended claims,
reference being had to the accompanyin drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

Before explaining in detail the present inven tion it is to be understood that the invention is not limited in its application to thedetails of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of bein practiced or carried out in various ways. Also it is to be understood that the phraseology or ter- 7 showing in plan the spray gun moving chain, the observer minology employed herein is for the purpose of description and not'of limitation, and it is not intended to limit the invention claimed herein beyond the requirements of the prior art.
In the drawings there is shown, by way of example, a spraying machine adapted for automatic spraying of workpieces such as frames, curved moldings and the like. The machine is termed automatic, since the only manual operations in connection with operating this improved machine is loading and unloading of the workpieces on the work conveyor, all other operations being performed automatically by improved means performing predetermined functions.
The machine illustrated in the drawings and hereinafter described is adapted for painting by spraying a frame molding for a motor vehicle body, said molding being in the form of a rectangular frame with rounded corners. It will be understood, however, that machines constructed in accordance with the present invention may be used for painting or spraying a great number of articles of various shapes, and, in fact, the machine hereinafter described may be adapted for painting workpieces of configurations different than that of the above specified frame molding which may be done by changing the guiding means of the spray gun and properly arranging the location and operation of the relay and switch means.
The machine illustrated in the drawings comprises generally a work conveyor adapted to receive workpieces to be painted, at one of its ends and to discharge the same at its other end. Superjacent of said conveyor there is provided a movable spray gun adapted to be moved in a path corresponding to the configuration of the frame moldings to be sprayed. The work conveyor and a chain moving said gun are actuated with the aid of electric motors. There are also provided means for opening and closing air conduits of said gun at the beginning and at the end of the operative movement thereof around said path, for starting and shutting ofl the spray gun. The machine is provided with a plurality of switches and relays included in an electric circuit connected to a suitable source of electric energy and adapted to control the above mentioned electric motors. Said switches and relays are so arranged that the work conveyor moves only until a workpiece to be sprayed reaches a predetermined position under said spray gun, whereupon the conveyor motor is shut off and the workpiece comes to rest. At this point the electric motor actuating the gun moving chain is automatically started and the spray gun moves around said frame, means also being provided to open the air conduit thereby starting operation of the spray gun. When the spray gun reaches the end of its working movement, the gunchain actuating motor is switched oflf, and the spray gun is shut off. Simultaneously, the work conveyor motor is switched on and the work conveyor begins moving to carry the sprayed workpiece to the discharge end thereof and to bring the new wakpie'ce into the spraying position under the sway gun.
Referring to the drawings and particularly-to Figs. 1, 4 and 6, the spraying machine illustrated therein comprises a frame made up of a plurality of members forming a table having legs l5 and horizontal members l6. On said table there is operatively mounted an electric motor I'I connected drivingly through a gear box !8 effecting suitable speed reduction, sprocket wheel I! engaged by a chain 20 driving a second sprocket wheel 2| with a shaft 22 on which said sprocket wheel 2| is mounted. The shaft 22 has two intermediate size sprocket wheels 23 and constitutes a driving shaft of the work conveyor adapted to carry workpieces past the spray gun.
The work carrying conveyor generally indicated by the numeral 24 comprises two endless connectors, in the present instance chains 25, driven by the sprocket wheels 23, said chains being passed around idler sprocket wheels 26 and large size idler sprocket wheels 21. There is provided four of such large idler sprocket wheels divided into pairs, each pair being operatively mounted on a shaft 28 having ends journalled in bearings 29 secured to the lower horizontal members 16 of the table.
To the links of the chains there are secured pieces 30 (see Fig. 5), the two opposing pieces of the chains 25 being connected by means of a bar or rod 3|. Since links of the chain 25 are relatively small, the bars 3| are arranged relatively close together, thus forming in effect a rather wide built-up flexible conveyor passing around the sprocket wheels and driven by the electric motor ll. Thus, when the electric motor I1 operates it rotates a sprocket wheel l9. Rotation of said wheel I9 is transmitted by the chain 20 to the second sprocket wheel 2| and the shaft 22. The sprocket wheels 23 secured on the ends of the driven shaft 22 drive the chains 25 and therefore the entire conveyor.
The work conveyor 24 is adapted to receive workpieces 32 which in the present instance are garnish moldings such as are used in motor vehicle bodies. The moldings are of a substantially rectangular form, thus presenting workpieces of closed linear configuration. The workpieces 32 are located on said conveyor by means of suitable means such as blocks 33 provided on the bars or rods 3|.
The conveyor 24 is adapted to move intermittently and to receivev workpieces at its receiving end, bring them to the spray gun generally indicated by the numeral 35 and to discharge said workpieces at its delivery end. Loading and unloading of the conveyor 24 is done by hand as was explained above.
Intermittent motion of the conveyor 24 is effected by opening and closing the electric circuit feeding the work conveyor motor l1, theopening of said circuit and consequently stopping the motor I 7 being effected at the moment when a workpiece reaches a predetermined position under the spray gun 35. In the present embodiment of the invention such switch is exemplified by the switching device 36 operated for performance of the above function by a relay 3! which relay is hereinafter termed the first relay. Said first relay is operated in turn by means of a photoelectric device, often referred to in the art as an electric eye, said device including a projector 3& fed from an electric circuit supplying electric current brought to proper voltage and amperage with the aid of a transformer 39 connected to the electric source, in the presentinstance the regular power line.- The projector 38 is adapted to throw a beam of light passing just above the conveyor and received by a screen of a light sensitive device 40 operatively connected to said first relay 31. The beam of light is adapted to be intercepted by a workpiece when the same reaches a predetermined position, such interception of the light beam causing the light sensitive device 40 to operate the first relay 3'! hose 5441, see Fig. 5.
the desired rotative speed at the drive shaft 43 carrying a drive pinion '44, the rotation of which is transmitted with the aid of a chain 45 to a driven wheel 46'. The wheel 46 is secured to a shaft 4'! on'the opposite end of which is secured a driving wheel 48 engaging a gun moving chain or conveyor 49. The gun moving chain 49 is adapted to move in a predetermined path corresponding to the configuration of the workpiece 52 which path is determined bythe guiding means generally indicated by the numeral 50 and comprising a built-up templet of a configuration substantially similar to that of the workpiece 32. a gun 35 by means of an arm or link 5i adapted to move bodily with said chain 49 making one complete revolution as the chain makesone complete turn. The link 5i is secured to the gun in such a way as to rotate the same as said link moves around.
Fig. 6 illustrates various positions of the gun in the rotating movement thereof. It should be understood that the actual path of the gun although similar in its configuration to the configuration of i the workpiece is considerably smaller than the workpiece. In many instances only rotation of the gun will be sufficient for spraying workpieces of enclosed configurations.
The gun 35 is carried by a head generally indicated by the numeral 52, said head being a struc- The chain as is connected with As. already explained, there are provided means, which become active at the moment of stopping of the work conveyor, operating to switch onthe spray gun motor 4|, and also to start the spray gun 35 by opening an air valve 65 admitting air under pressure to said gun 35 through the air conduit 51. Said means comprise in the present embodiment of the invention a second relay 66 electrically connected to said light sensitive device 40, and to the power line through the switch 35a as shown in the diagram of Fig. 10; When the work conveyor stops, the second relay 66 switches on the gun conveyor motor 4! and energizes the solenoid 61,
which overcomes under said conditions, the resistance of the spring 58.
On the gun moving chain d5there is provided a pin or block 69 adapted to engage a hook It operated by an electric eye solenoid H. The hook Hi is adapted to operate the. switches 36 and 36a. A spring 12 is compressed when the hook it is caught by the moving pin 65, and when the hook being raised by the solenoid ii is released, said spring expands, returning the switches 35 and 36a into the positions shown in Fig. 10. This causes switching on of the work conveyor motor it asexplained. When, however, the solenoid ii is de-energized and the hook it is engaged by the pin til, the switches 35 and 36a are operated to stop the spray gun motor M and the gun moving chain 45. At the end of the movement of the gun moving chain 45, the above means operate to start the work conveyor, as already described, thus beginning a new operative cycle.
A general switch ll-i is provided for the purpose" of starting and stopping the entire machine.
When said switch is closed the work conveyor beture providing three concentric conduits, 53, 53a,
and 5%, the central conduit 53 having a connection for a rubber hose 54 connected to the paint supply tank 55. The paint from said conunderstood that the concentric conduits are formed as shown in Fig. 9 by concentric tubes connected to the gun and rotatable therewith. Although the hose lines 54, 56 and 5i are fixed against rotation with. the head 52 they remain at all times in communication with the concentric tubes during any rotative movement thereof in response to corresponding movements of the gun.
The head 52 is rotatably carried by an arm 53 hingedly connected as shown at'59 to an arm 69 hingedly secured to the post 5! secured to the plate 62. The plate 62 carries the gun actuating and guiding means, and is in turn secured to the horizontal members i6 of the table or frame of the machine.
gins moving. It is desirable to put a first workpiece on the conveyor when the same is still stationary, since if no workpieces are carried by the conveyor, it will move continuously, but the spray gun operating means will remain inactive.
Since the relays 5i and are of a conventional design, the diagram of Fig. 10 is believed to be quite sumcient for those skilled in the art to effect proper connections of the devices combined, tracing of all circuits under the conditions men-' tioned being deemed unnecessary.
