Definitions

  • the containers are transferred from an inspection star wheel rotor to a separating star wheel rotor.
  • a common dirty bottle segregating mechanism is associated with the separating star wheel rotor and a common regulating unit which responds to the several inspection sensors for selectively actuating the segregating mechanism to segregate dirty from clean containers on the separating rotor.
  • the clean containers leave the separating rotor via a discharge conveyor, and the dirty bottles leave the separating rotor via a reject conveyor.
  • This invention relates to apparatus for inspecting empty, open top, transparent containers such as bottles, glasses and so on, which are transferred in upright position by means of bottle transport starwheels.
  • machines of the type described typically do not have their own drive. Accordingly, they only work if sufficient pressure is delivered thereto from the conveyor belt.
  • the bottle starwheels of such machines must be driven by the bottles. Accordingly, the speed of the machine varies, and this adversely affects all the following machines in the plant.
  • At least two separate inspecting scanners are arranged in the bottle passageway in the region of the central inspection star wheel rotor. These separate scanners trigger a common bottle reject apparatus.
  • a third conventional inspecting scanner may be arranged at the top side of the lip of the bottle mouth in the region of the central inspection star wheel to inspect this portion of the bottle and trigger the reject mechanism.
  • paratus for removing foam at the bottom of the bottle is located between the infeed of the bottle and the base scanner.
  • the foam removing apparatus desirably comprises brushes rotating in a water bath and against the bottom of the bottle.
  • the wall scanning apparatus includes at least two radial pencils of light rays coming from a stationarily arranged light source crossing the bottle path.
  • rotating devices are arranged for partially turning the bottles so that the bottle wall sections intercepted by the different light beams overlap. This insures scanning of the entire area of the bottle wall. Only one light source located in the middle of the region of the central star wheel is needed for the wall scanner operation.
  • the receivers for the light beams are advantageously located outside the bottle path.
  • Another feature of the invention relates to the regulating unit by which all dirt scanners actuate through a common reject mechanism selected bottle holders (holding and releasing arms) which segregate dirty from clean bottles on the separating or output star wheel rotor.
  • the scanners selectively trigger an amplifier which energizes an electromagnet which lifts a reject cam which, in turn, actuates mechanism which positions appropriate bottle holders in holding or non-holding position.
  • the holder When in holding position, the holder directs the dirty bottle to a reject conveyor.
  • the reject cam is not activated. Accordingly, the holding and releasing arm corresponding to such clean bottles is not selected, whereupon such bottles are delivered by the output star wheel to the normal output conveyor of the machine.
  • Another feature of the invention relates to slide ramps which contact the bottoms of the bottles between successive star wheels,
  • the ramps provide an adjustment for accommodating for varying sizes of the bottles.
  • the ramps raise short bottles and lower tall bottles so that all bottles, regardless of height, fit the machine.
  • a bottle sensor signals a device which controls the speed of the machine. In case of missing bottles or stagnation of the bottles, the bottle infeed is blocked and the speed ofthe machine is reduced to a minimum.
  • the present machine provides a novel and compact arrangement of a variety of inspection devices around the central star wheel.
  • Each device independently signals a simple, inexpensive, mechanical reject device which mechanically stores and transmits the separate reject signals.
  • the mechanism of the machine is easily understood and repaired by the machine operators.
  • the wall inspection device of the present invention further has the great advantage in that the bottles need not be rotated by separate mechanism for each bottle as they pass the wall inspection zone.
  • the bottles need only be partially turned as they travel on their path. This is accomplished simply by pressing them laterally against friction rails.
  • FIG. 1 is a diagrammatic plan view of an automatic inspection machine embodying the invention, certain electrical connectors being also shown schematically.
  • FIG. 1a is a diagrammatic view similar to FIG. I, but showing a modified embodiment.
  • FIG. 2 is another diagrammatic plan view of the machine of FIG. 1, showing certain parts not shown in FIG. 1 and omitting certain parts which are shown in FIG. 1.
  • FIG. 3 is a diagrammatic side view of a portion of the device of FIG. I, and showing the ramps for varying size bottles to fit into the machine.
  • FIG. 4 is a diagrammatic developed elevation of the inspection star wheel rotor illustrating an arrangement of the cleaning elements for the removal of foam from the bottom of the bottle.
  • FIG. 5 is a fragmentary view partly in cross section and including elements shown diagrammatically of the mechanism for triggering the reject mechanism.
  • FIGS. 6a to 6d are fragmentary side elevations of the segregating star wheel illustrating various stages in the actuation of the holding dogs by the actuating arm.
  • FIG. 7 is a diagrammatic view which illustrates the overlap of the light beams over various parts of the bottle.
  • FIG. 8 is a diagrammatic side view of the scanner for inspecting the bottoms of the bottles.
  • FIG. 9 is a vertical cross section through the separating star wheel rotor of a machine embodying the invention.
  • the bottles 3 leaving a washing machine are transferred by means of the infeed conveyor belt 1 into the operating region of the inspection machine.
  • the bottles 3 are transferred by the infeed screw or worm 2, as shown in FIG. 1, to the infeed star wheel rotor 4, which transfers the bottles to the central inspection star wheel rotor 5.
  • the bottles 3 Just after the bottles 3 enter the inspection star wheel rotor 5, they pass the zone of a top lip or mouth inspection scanner 6. Thereafter, the bottles 3 are subject to a side wall scanner 42 and pass successively through three light beams 9 coming from a common light source 39 which is stationarily arranged in the central light well 8 of the wall inspection or scanning device.
  • the beams 9 are respectively aimed at light sensitive receivers 10 at the periphery of the inspection rotor 5.
  • FIG. 1 there are short friction pads or rails 14 intermediate the successive light beams 9.
  • the bottles 3 are pressed laterally against pads 14, thus to effectuate intermittently a partial rotation of the bottle about its upright axis.
  • This arrangement insures that all portions of the side wall of the bottle will surely be scanned by one or another of the beams 9 as indicated in FIG. 7.
  • FIG. la shows a modified arrangement in which a single long pad or rail 14 continuously turns the bottles as they pass the zone of the side wall inspection device 42.
  • the shaded areas in the representation of the bottle 3 in successive positions in FIGS. 1 and 1a indicate the portions of the bottle walls which are scanned as the bottles pass through the scanner 42 from one light beam to the next.
  • the bottles 3 Shortly before their transfer to the output or separating star wheel rotor 11, the bottles 3 pass through the region 7 of the device (FIG. 8) for inspecting the bottle bottoms near the end of the bottle passageway in the inspecting star wheel rotor 5.
  • a bottle sensor or feeler 15 is located adjacent the infeed conveyor.
  • a bottle sensor or feeler 16 is located at the output conveyor. These feelers sense the flow of bottles to insure proper bottle flow rate. This arrangement is also shown in my copending U.S. Pat. No. 3,607,547 aforesaid.
  • the bottle sensor 16 is actuated and through it a variable speed drive 26, 27, 28, 29, (FIG. 2) adjusts the machine speed up to its capacity.
  • the bottle stop 17 at the input conveyor is concurrently withdrawn, thus permitting continuous infeed of bottles.
  • the regulator 30 adjusts the variable width pulley 27 for V-belt 41 from the pulley 28 of motor 29, thus to vary the speed of drive 26.
  • sensor 15 will feel no pressure. This will trigger the variable speed drive to reduce machine speed to a minimum.
  • the regulating unit can be electric, pneumatic or mechanical.
  • the regulating units 35 are electromagnets (FIGS. 2 and 5).
  • Each regulating unit 35 is subject to actuation by the amplifier 50 which in turn is subject to pulsing from any one or more of the mouth inspection device 6, the bottle bottom inspection device 7 and each ofthe light ray receivers 10. Accordingly, it is immaterial at which of the different inspection stations dirty bottles are recognized.
  • Each electromagnet 35 has a sliding cam stem 20. When the sensing of a dirty bottle triggers the magnet 35 for the station occupied by the dirty bottle, the stem 20 for that magnet is lifted and held in lifted position by permanent mag net-type holder 20.
  • the sliding part 20 Only after the transfer of the bottles to the separating star wheel rotor 11 will the sliding part 20 be again brought back by a rail, not shown, to its retracted position.
  • the reject mechanism includes blocking units or dogs 24.
  • the dogs 24 are pivotally mounted on pintles 19 on the lower star arms of separating star wheel 11. These dogs 24 are selectively actuated by the swing arm 21 of transfer unit to cause rotation about its axle shaft 23 of the corresponding bottle holding element 25.
  • Each axle 23 has a coil spring 60 (FIG. 9) which biases the shaft 23 to rotate clockwise in FIG. 2.
  • the dogs 24 block this clockwise motion of the shaft 23 and holder arm 25, until the dog 24 is swung down to an out of the way position by pressure of transfer arm 21 (FIG. 6b), whereupon spring 60 swings the arm 25 over the top of the retracted dog 24 (FIGS. 6c and 6d) and into a dirty bottle retaining position.
  • the shafts 23 also carry arms 61 (FIG.
  • cam rollers 22 acted upon by the cam 18 which will withdraw the holding arms 25 from retaining relation to the dirty bottles on star wheel 11 when the bottle reaches the reject conveyor 12.
  • the profile of cam 18 is such that holding arm 25 continues to hold the dirty bottle as separating star wheel rotor 11 carries it past discharge conveyor 13. Thereafter, the cam 18 exerts pressure on cam roller 22 to turn shaft 23 counterclockwise against the bias of coil spring 60 and gradually withdraw holding arm 25 away from confining relation to the dirty bottle.
  • arm 25 cams against the inclined top of blocking dog 24 to restore the dog to its initial position against stop 53 (FIG. 60).
  • the reject amplifier 50 will not be pulsed. Accordingly the electromagnet 35 corresponding to the clean bottle will not be energized and sliding cam stem 20 will remain retracted. Accordingly, neither the transfer arm 21 nor the blocking dog 24 will be actuated. Accordingly, blocking dog 24 will maintain its FIG. 6a position and prevent coil spring 60 from turning holding arm 25 into reject position.
  • FIGS. 6b and 60 show the release of the holding arm 25.
  • FIG. 6d shows how the holding arm 25 is brought via its roller 22 by the cam disk 18 to its starting position (FIG. 6a) by pushing it over the blocking dog 24.
  • FIG. 3 shows schematically how the bottles 3 are lifted by a slide face or ramp 31 touching the bottle base in the region of the transfer of bottles from the infeed star wheel 4 into the central star wheel 5.
  • bottle 3 is shorter than standard and is lifted by ramp 31 into proper carrying position with respect to star wheel 5.
  • slide face or ramp 32 touching the bottle bottom in the region of the transfer of bottles from the center star wheel 5 to the output star wheel 1 1 in order to bring overtall bottles, such as tall bottle 3", hanging in the central star wheel 5 to the bottle conveyor belt 33.
  • the base scanner 7 of FIG. 8 is arranged at the end of the bottle passageway in the central inspection star wheel 5 in order to provide a long distance for removing the foam from the bottom of the bottle before it reaches the bottom scanner.
  • FIG. 4 shows the foam remover which comprises rotating brushes 37 immersing into a water bath 38. These are arranged to brush the foam from the bottom of the bottle in the region of the central star wheel 5, as the bottles travel on their path through side wall scanner 42.
  • the brushes can be replaced by a foam remover comprising a fluid nozzle jet 51 of air or water 52, as shown in FIG. 4.
  • FIG. 7 shows schematically how the three light beams 9 of the wall inspection device 42 overlap.
  • Section I shows the inspected part of the bottle wall of the first light beam 9.
  • the bottle 3 makes a partial rotation of about 60 and passes then through the second light beam 9 of section II.
  • the bottle then passes the third wall inspection station after a further partial rotation of 60 and is impinged by the beam of section III.
  • the overlapped beams give good assurance that all parts of the bottle wall will receive the direct rays of one or the other of the three beams.
  • FIG. 8 shows a bottom scanner.
  • a light source 43 for light rays 44 is located in a light well 36.
  • the rays of light 44 are changed into diffused light by a pane or opalized glass 45.
  • the rays 48 coming from the pane of opalized glass 45 are collected by a lens 46 and are transmitted via a rotating scanner 47 to a receiver 10.
  • the receiver triggers an amplifier 50 via the circuit lines 49 whereby the amplifier 50 actuates the appropriate electromagnet 35.
  • the lip of the bottle mouth is illuminated by a light source in a conventional mouth inspection device 6 in FIG. 1.
  • the image of the bottle mouth reflects to a rotating prism which transfers the reflection to a photocell. If the lip is broken, an uneven reflection will appear, and an impulse is transmitted via an amplifier 50 to the appropriate electromagnet 35 which actuates its sliding part to set in motion the reject mechanism for that particular bottle.
  • the automatic inspection machine can also operate with less than all of the three inspection devices functioning, depending upon requirements.
  • the machine is versatile because as requirements demand, additional inspection devices can be added without materially increasing expense.
  • the inspection machine can be adapted to inspect bottles of different height, diameters and shapes.
  • FIG. 1a differs from the embodiment of FIG. 1 with respect to the form and operation of the bottle turning rail 14, as hereinbefore described, and also with respect to the location of the reject conveyor 12.
  • reject conveyor 12 is perpendicular to discharge conveyor 13 and line up tangentially with output star wheel 11.
  • reject conveyor 12 is parallel to discharge conveyor 13 and receives rejected bottles from star wheel 11 via a transfer star wheel 54.
  • the inspection sensor for the side wall of the container comprises successive light beams through which the container passes successively, and mechanism to rotate the container between successive beams.
  • the common dirty container segregating mechanism associated with the separating rotor comprises container holders having holding and nonholding positions, and mechanism responsive to the regulating unit to selectively position the holder in one or the other of said positions.
  • the container holders comprise arms spring biased toward container holding positions, said mechanism comprising blocking dogs restraining said arms from moving toward said container holding positions and dog displacing arms responsive to the regulating unit to displace said dogs from blocking relation to the arms.
  • the mechanism further comprises a sliding cam shaft actuated by the regulating unit, said dog displacing arms having a portion in the path of the actuated cam shaft whereby to trigger said mechanism responsive to the actuation of the regulating unit.
  • the regulating unit comprises an electromagnet which energizes the sliding cam shaft and a holding magnet which retains the cam shaft in its actuated position.
