13 Claims. (Cl. zoo-n1),-

The invention relates to the inspection of fluids in bottles and .has as an obiectthe provision of improvements upon the machine of this charac- George Philip S t on October 11, 1938, for carrying out the process claimed in said patent.

It isa further object of the invention to improve upon the machine of said patent generally, and particularly in the drive, the provision for mixing the liquid, for oscillating the testing light,

and for ejecting bottles the contents of which contain a foreign body.

Further objects of the invention will appear from the following description 'when read in connection with the .accompanying drawings showing an illustrative embodiment of the invention, and wherein:

-As shown the device comprises .a supporting table l5 mounted on a base I 8 supported by level-. ing screws IL' Standards lS-rise' from thetable ii for port of a plate l9 having a circularopening 29. V

-. Mounted tor revolution -on a central standard II is a turret 22 carryinga ringzear 29 uponits a speed-reducing mechanism housed in a casing c I is a continuation in part of" George Philip Stout above-referred to, is carried out by the passage or radiant energy through I stationaryand the contents are in motion.

. ing apparatus is shown release To cause revolution of the bottles with consequent eflect upon the contents thereof there are Mounted for revolution in said turret 22 adjacent its periphery, there are a plurality of bottle cups 29 carried by hollow stems 3|]. each provided with a drum 3| for causing revolution of the cup. The turret 22 is shown as mounted .upon ball bearings 32 upon the standard 2!.

The standard 2!, which is tubular, has a turret cover plate 33 secured as by cap screws 36 toits upper edge.

To feed bottles to the cups 29 there is shown a star wheel 35 operating in a. manner conventional with bottle-handling. apparatus, shown as driven by means of gearing similar to the gearing 86, Figure 2, for drive of the star wheel 3] for removing bottles from the cups. Thus the in and out feed devices are accurately geared to work in unison with the revolution of the turret.

Bottles are delivered to the star wheel 35 by conveyor I35. To cause the conveyor to deliver the bottles well toward the bottom of the recesses of the star wheel a deflector I36 is shown pivoted at I31 and yieldably urged toward the star wheel by spring I38. A gate member I39 forms the opposite side of the infeed throat,

which gate is shown as pivoted at I40, and. may

be actuated about its pivot intime with the revolution of the star wheel by means not shown to bottles at the proper times.

shown friction bands 39, 39, preferably'driven by a motor not shown, separate from the motor 29, and mounted upon the table l5.

The band 38 is driven as shown by the arrow .in-adirection the reverse of the band 39 and desirably at a substantially greater speed. The bands 38, 39 act upon the drums 3| for driving the individual cups 29, and the band 38 is desirably operated at a speed substantially inexcess of the speed of the band 39, for the purpose of causing a violent agitation of the contents of the bottle when the direction of revolution thereof is reversed.

The testing of the contents of the bottles for foreign bodies as described in the application of while the bottles are In accordance with the present invention. the testas mounted upon an 49 mounted in bearthe, bottles and contents oscillatory hollow spindle is so ins: u m the upper end .of the standard 2:, the

spindle carrying the optical equipment casing 42. The details of the optical equipment and the circuits involved form no portion of the present invention and may be similar to that disclosed in the Stout application, with the single exception that response to a foreign body in a bottle will cause the breaking of a controlled circuit instead of the making of such a circuit as in the Stout application.

Mounted upon the turret 22 there is a circular wall 43 having windows 44 opposite each of the cups 29, which wall 43 carries an upper ring 45 in which are revolubly mounted spindles 48 each bearing a cup 41 for engagement with the bottle cap for the purpose of keeping the bottles centered during their revolution.

The light box structure includes an arm 48 connected to the lower end of the spindle 40 having an upwardly directed portion 49, Figure 8, connected to a vertical member 50 carrying the light sensitive cell in a casing and a connecting member 52 secured to the box 42 overhanging the ring 45, whereby thecasing 5| partakes of an oscillatory movement of the box 42 and spindle 40.

To cause oscillation of the testing mechanism in one direction exactly in synchronism with the movement of the bottles with a quick return between tests, the arm 48 is shown as carrying a roller 53 pressed by a spring 54 attached to the arm 48 and anchored at 55, Figure 4, to the table, the roller 53 being thus held against a cam 58 carried by the spindle 51 upon which the gear 24 is mounted. The form of cam 58 is shown in Figure '7. g

To stop the rotation of cups 29, a brake shown in plan view in Figure 13 is provided. As there shown a bell crank 58 is pivoted at 59 to a lug 80 carried by the light box structure. A brake block 8| is secured to the arm 82 of the bell crank. To urge the brake block against the drums 3| a spring 83 pulls upon a link 84 anchored in arm 85 of the bell crank, the spring 83 having abutment against rib 88 upon arm 49.

The brake block 8| projects further from arm 82 at its heel 81 than at its point 88 and is of a length in excess of the spaces between successive,

It follows from this structure that when the heel 81 leaves one drum, during retro- I grade movement of arm 48, 49, the block will be drums 3|.

mal retracted position by a coil spring 82 against a stop member 83. The arm 84 is in turn pivoted upon arm 8| and is urged against a stop 85 also carried by the turret cover 33 by means of a spring 88. The stop 85 is preferably faced with rubber to cushion the stoppage of the arm 84.

When one of the'pins 18 is raised by breaking of the current in the solenoid 1|, it is thrown upwardly so as to come into contact with a cam 81 carried by shaft 19, thereby forcing the arm 8| and 84 to the right, as shown in Figure 4, to pass through the window 44 opposite the defective bottle and by virtue of the pivotal mounting of the arm 84 thearm can yield to the movement of the turret while the arm 8| is forcing the bottlecontacting member 88 against the bottle to force the bottle out of the cup to fall upon a surface 89 from which they may be removed in any manner desired.

When the pin 18 is raised it is locked in raised position by means of a spring-pressed pin 90, Figure 9, and held in this position until the revolution of the turret brings the pin into contact with a cam 9| carried byturret cover 33, Figure 6, which restoresany raised pin to normal position.

To allow defective bottles to be removed there is shown a cap lifting cam 92, Figures 1 and 2, and to allow removal of the bottles from the star wheel 31 there is shown a second lifting cam 93,

solenoid, it results that failure of current in the test circuit will cause de-energization of the re-.

ject solenoid with consequent "rejection" of all bottles both good and bad until the defect is remedied. Hence a defective bottle cannot be passed during failure of the test.

As shown the cam 58 is shaped to provide synchronized motion of the test light casing 42 with the bottle cups during 240 of the revolution-of the cam and a return movement of 42 during 120 of the revolution of the cam and to provide a motion corresponding to a sine curve.

12 overcoming a compression spring 13 anchored to the rod by means of lock nuts 14 and abutting against a lug 15 to hold the rod 12 down to keep a cam 18 carried by arm 11 mounted upon the rod 12 out of the path of movement of pins 18, of which one is provided for each bottle cup and mounted in the turret 22.

The pins 18 as shown in Figure 9 retain their lowermost position by gravity but when the cam 18 lifts to the dotted line position in Figure 10, the movement of the pins 18 into contact. with the cam 18 will cause them to be .raised to the dotted line position in Figure 10 to act upon the ejecting mechanism.

As shown in Figures 1, 4, and 5, the ejecting mechanism comprises a shaft 19 mounted in a bearing 88 carried by the turert cover 33. Car- With a speed of the turret acting to test 120 hottles per minute, there is thus provided a period of one-third second for the inspection test, which is ample when the bottles have been spun at a speed of substantially 900 R. P. M. for a time fect dispersion of the syrup through the other liquid in the bottle than other mixing devices heretofore used, which is of importance in a dependable inspection.

while on the machine, and-access of the'syrup" to the mechanism would be detrimental to its operation. The machine of the invention has been formed to protectthe mechanism from access of liquids. To this end the turret cover 83 hasa downturned lip lapping with an upturnedmarginal rib 88 surrounding the recess in-the turret. The upper surface of the turret about and. between the bosses 91 in which the cups :9 revolve, slopes downwardly and outwardly as shownv at 88, Figures 3 and 5, andat its extreme outer edge the turret is formed beneath with an annu-.

ment"!!! of opening 20 'in.the plate IS, a shield MI is secured to the arm 159 which oscillates in said enlargement space, the shield having an up-' tnmed lip entering the groove 99. The surface of plate 19 slopes from the left as seen in Figure 2 to the right in said Figure, as indicated by dotted line at I02. An upstanding flange IE3 is provided around the opening 20 and the enlargement Hill to prevent liquid on plate 19 from entering the opening it.

Conveyors of the type indicated at B5 are in common use'in bottling plants and bottles are commonly moved from one machine to another by such' means. The machine of the present invention may be withdrawn from use without interfering with movement of bottles on the conveyor to and from the other machines, by merely removing the guides IM, and I35 and the star wheels 35 and 31, .when the bottles will pass the machine uninterruptedly.
