7 Claims.
This invention relates to inspection devices, and more particularly to that type employing inter alla a photo-electric cell in the detecting of foreign ingredients in transparent containers such as commonly used in the merchandising of beverages and the like whereby a single machine beverages. may 'be speeded up to accomplish the same re- I have heretofore disclosed a device of this sults now produced by two such devices. type in my United States Patent No. 2,132,447, Another object is to provide simplicity of opissued October 11, 1938, for Processes and appaeration and economy in construction of a beverratus for inspecting fluids;` -and machines inage inspection device. volving this basic inventive concept are coming A still further object is to make possible eniincreasingly into commercial use.

This in large plants such as those found in 'somo 45 rotation of the containers is abruptly stopped, cities, a higher rate of bottling is uniformly pracimmediately before inspection, through brake ticed, which means that two inspection machines arm 23 (Fig 2) plvotally mounted at 24 and instead of one must be employed. This not only Operating against the tension of spring 25 Botrequires a dwelling 0f @Very other bottle in the tles enter the machine through conveyor 26 and line t0 the auxiliary machine but requires an 50 infeed star wheel 21 and leave same with the asinitial extra expenditure for the other machine, sstance 0f Outfeed star Whee1 28, there to be WhiCli` besides representing a Considerable ndirected either to the ordinary discharge conveyvestment in dollars and cents, is undesirable at or 29 or a reject conveyor V3@ with the assistance a time when supplies and materials of this type of revolving disc 30a, this latter occurring when the presence of a foreign particle in a bottle. has
are increasingly dilicult of procurement and when national policy demands conservation in every way possible.
An object of my invention is'to provide apparatus for and a method of inspecting bottled resulted in an amplified impulse setting up means whereby solenoid 3 I, which normally holds reject arm 32 in an open position, becomes de-energized with the result that said arm, which is pivoted on a spring at 33, assumes the position shown in Fig. 2, the bottle containing the undesired substance then being by-passed or rejected when it reaches this point and such reject condition continuing until solenoid 3l again becomes energized, which may be effected by conventional means.
A cap or receiving templated to engage element 34 (Fig. 3) is conthe tops of bottles in the machine, said cap being held in position against the tension of spring 35 and allowed freely to revolve either on shaft 3B or in conjunction with said shaft. As the bottle enters the machine, a fixed cam guide automatically raises element 34 so that the bottle may be secured in place, said cap then descending and remaining in place until a similar guide lelevates it and releases the bottle just as such is about to leave the machine.
Attention isnow directed to the optical system which constitutes an important part of the instant invention, same comprising a source of light 31 suitably screened as at 38 and backed by a reflector 39, said radiant energy being passed through a lens 40 so as to direct its beams through two or more openings 4l of turret l2, the beams then passing through bottles being inspected in a more or less conventional manner.
Particular attention is now drawn to the rear or receiving end of my optical system, same constituting a plurality of photo-electric cells 42 spacedly mounted on a silent or roller chain 43, which chain operates on a pair of open-toothed gears 44 mounted on shafts 45 in such a manner that chain 43 and associated photo-electric cells revolve freely in the path established by said gears upon application of an appropriate external driving force, which in this instance is represented by teeth 46 positioned around the outside edge of turret l2 in such a manner that as said turret revolves the teeth engage 43 and thereby result in bottles adjacent said teeth travelling together in synchronized relationship with individual photo-electric cells on said chain for a stated interval during which inspection occurs.
That is, upon a bottle's coming into juxtaposition with a given photo-electric cell, the focused light from lamp 3l passes through the whirling contents of the bottle and on to the cell. Any interruption in said beam of light, such as would be caused by a foreign particle passing into or out of said light, is immediately registered by the cell, amplified and employed to cause a rejection of the objectionable container.
From the foregoing it will be apparent that my invention results in the speed of inspection being greatly increased, it no longer being necessary to wait for the optics to return to their initial position before starting inspection of another bottle, each bottle in effect being met at the threshold by a photo-electric cell which travels with it during such time as may be required for inspection. the number of cells on chain 43 and the manner in which said cells travel through a given course guaranteeing that there shall be no waiting, but that each bottle shall be promptly and expeditiously inspected.
This arrangement makes possible the elimination of the extra machine now employed in high speed plants, and at little additional cost.
While I have described in detail certain ferred structure in disclosing my invention,
pre-
will be understood that I do not intend to limit myself thereby, nor is the exact method described herein to be unduly restricted, it being my intention that the appended claims shall be given a construction and scope fairly in keeping with my contribution to the art.
