  • FIG. 6 shows a detail on an enlarged scale of a modification ofthe mechanism shown in FIG. 5, and
  • FIG. 7 is a circuit diagram.
  • the apparatus comprises a stand 2, an inspection station 4 situated over a lamp house 6 in the lower housing, a sorting head 8 supported above the inspection station by a column 10 extending from the stand, a star wheel 12 mounted for rotation in the direction shown by the arrow about a vertical axis on a hollow shaft 16 journaled in a bearing 14 in housing 2 so that one point on its periphery is adjacent the inspection station 4, a conveyor 18 adapted to advance bottles in single file towards the star wheel and away from the star wheel, a spring belt 20 on free-running pulleys 34 supported from the column 10 by brackets, the belt holding the bottles against the star wheel, and a rotating table 35 within a pen 37, adjacent and to one side of the star wheel, or a second conveyor 36 (see FIG. 3) extending tangentially away from the star wheel at a point further advanced relative to its direction of rotation.
  • the conveyor 18 runs alongside the inspection station 4 beneath the star wheel 12, so that advancing bottles are constrained by the action of the star wheel and the belt 20 to leave the conveyor, pass through the inspection station 4, and to return to the conveyor, this last step being assisted by a further idling star wheel 13.
  • the column 10 may be moved forwardly or rearwardly relative to the stand 2 on slides 3 by means of a handwheel l1 and an associated screw drive, whilst a further handwheel 5 on the column provides vertical adjustment of the sorting head 8 on slides 7 carried by the column 10, thus accommodating different bottle diameters and heights.
  • the star wheels 12 and 13 are also interchangeable to suit different ranges of bottle size.
  • the star wheel 12 comprises two discs 22, 24 linked by struts 26 and is detachably mounted on the shaft 16.
  • the lower disc 22 has a series of peripheral recesses 28 each adapted partially to receive the body of a bottle, and the upper disc 24 a corresponding series of recesses 30 adapted partially to receive the neck of a bottle.
  • the disc 24 comprises an inner flange portion 38 carried by a hub disc 39, an upwardly extending frustoconical portion 40, and a radially extending flange 42, the last being provided with the recesses 30.
  • a window 44 is provided in line with each recess 30 so as to lie adjacent a portion of the neck of a bottle whose neck is received in that recess, and a further series of smaller windows 46 is provided adjacent the first windows, but circumferentially displaced so as not to lie in line with the neck of a bottle received in the recess concerned.
  • valve block 48 Also mounted on the shaft 16 is a valve block 48 (see FIG. ll) carrying a number of radially extending tubes 50 (for clarity only two are shown) in line with the recesses in the discs, each tube terminating in a rubber suction cup 52 adapted to contact the body ofa bottle received by the recesses in the two discs.
  • the valve block 48 contains a valve associated with each tube and having positions connecting each cup 52 via its tube 50 with the atmosphere or with a vacuum pump contained in the base 2 via the hollow shaft 16 and a rotary joint, the valves being operated by plungers 54 (again only two are shown) extending vertically through the valve block.
  • the star wheel 12 is rotated by the pressure of the incoming bottles on the conveyor 18, each bottle reaching the wheel being received by a pair of the recesses 28, 30 and being carried thereby through the inspection station 4 and back onto the conveyor 18.
  • a solenoid 56 is so arranged beneath the valve block 48 that energization of the solenoid whilst a bottle is in the inspection station will drive upwards that plunger 54 operating the valve associated with the cup 52 contacting the bottle in the station, thereby evacuating the cup and holding the bottle firmly in the pair of recesses so that it cannot pass back onto conveyor 18 and is instead carried by the star wheel 12, either into engagement with a guide 58 which holds it in the recesses until it is released onto the platform 35 (FIG.
  • the inspection station 4 comprises a platform 60 over which the bottles pass, the platform having a clear or opalised window 62 situated so that in their progress over the platform each bottle will pass exactly over the window.
  • Light from the lamp house 6 shines upwardly onto the underside of the platform so as to illuminate the window 62, and through this window, the bases of the bottles, an inclined mirror 64 (see FIG. 4) within the head 8 and level with the portion 40 of the disc 24, and a window 66 in a mirror housing 63 (see FIG.
  • Light passing through the window 62 is transmitted up the walls 68 ofa bottle positioned thereover and illuminates these walls, throwing into contrast any labels these may carry, light radiated by any ceramic label on the bottle walls being picked up by two or more photoelectric cells 70 distributed around the bottle ofthe level at which labels, normally ceramic labels, are expected to occur. If a sufficient number of cells is used, depending on the circumferential extent of the label concerned (two will normally be sufficient), light will be received by at least one of the cells from the edge-illuminated label, and the total output or resistance of the cells will be different from that expected from a bottle without a label.
  • base lighting in the manner described is an important feature since it gives a large difference in overall output or resistance for labeled and unlabeled bottles and the light emitted by a label may be easily received by a cell placed at the opposite side of the bottle, whilst by the alternative use of reflected light, the ceramic label may have a reflectivity similar to that of glass.
  • the light reflected from the mirror 64 passes through a window 72 and a diffuser 78 in the housing 8 towards a photoelectric cell 76 mounted in a holder 84 behind an aperture 77 in a depending portion 74 of the housing 8 extending into the frustoconical portion 40 of the disc 24, the cell 76 being arranged so as to be in line with a window 46 in disc portion 40 and the window 72 when the base ofa bottle engaged by the corresponding recesses 26 and 28 is exactly in the inspection station 4.
  • the cell 82 may be positioned above the bottle to receive light passing through the bottle base via the window 62, or a combination of two cells measuring the color transmission of base and neck (or wall) may be used.
  • the amount of light falling on the cell 76 will depend on the light-absorbtive properties of the glass of which the bottle is made, and it is found that, at least with the photoelectric cells currently available, and with the glasses commonly used for bottle making, the color filter is necessary to provide sufficient differentiation in the cell response between the transmission characteristics of glasses of different color and shade. Further, the use of diffused light is essential if consistent transmission through bottles of the same color is to be achieved, since effects due to refraction of the light by the glass then tend to cancel each other.
  • the light passing through the aperture 66 falls on the overlapping ends of a pair of elongated shutter members 86, 88 above which is situated a further photoelectric cell 90.
  • the overlapping ends of the shutter members are formed with apertures 92, 93 respectively and form a shutter assembly which can be opened to allow light from the window 66 to fall on the cell by alignment of the two apertures 92.
  • the member 88 is pivoted on a sleeve 89 carried by a vertical shaft 94 supported by a bearing assembly 87 and carrying a feeler 96 at its lower end, and the sleeve is biased by a spring 97 anchored by a screw 98 so that the feeler 96 projects into the path of the top lip of a bottle 100 passing through the inspection station 4.
  • the feeler 96 can thus be set with vertically and angularly relative to the member 88 so that when an angle 102 in the feeler 96 engages the lip of a bottle of a desired height and neck diameter, the aperture 92 in the free end of the member 88 will be in alignment with the window 66 and the cell 90. if the neck of the bottle is too large or too small, the feeler will be deflected more or less, and alignment will not occur; if the bottle is too tall or too short, the feeler will be deflected too much, owing to the bottle engaging the feeler above the notch, or not at 11, owing to the bottle missing the feeler.
  • the member 86 is pivoted on a sleeve 101 carried by a vertical shaft 104 supported by a bearing assembly 103 and carrying a feeler 106 at its lower end, and the sleeve is spring-biased by a spring anchored by a screw 108 so that the feeler 106 projects into the path of the bodies ofa bottle passing through the inspection station 4.
  • the free ends of the members 86 and 88 are forked so that the arms 111 of the forks will limit movement of the members by contacting stops 113. Any excess movement of the feelers 96, 106 will be accommodated by the springs 95, 109.
  • the cell 90 will be exposed to light from the window 66 since the apertures 93 will be in alignment with each other, the cell and the window. Moreover the arrival of a bottle at the inspection station will result in light falling on the cell 76, in filtered diffused light which has passed through the neck of the bottle falling on the cell 82, and in light radiated from a label on the bottle falling on the cells 70.
  • the dimensional tolerances permissible in the bottles being inspected are set by the dimensions of the apparatus 92. Since in the case of bottle diameter at least the tolerances required will vary with bottle size, some means for adjusting tolerance is desirable. This is achieved by the arrangement of FIG.
  • a pin 51 is carried by a plunger member 53 of the micrometer screw device 110, this pin projecting through a slot 55 in an outer sleeve 57 of the device.
  • a shutter plate 59 is pivoted to the plate 88 so that one end partially obturates the aperture Q3 and a grommet 61 mounted on the other end engages the pin 51.
  • the micrometer screw device is extended so as to set the feeler for larger bottles, the degree of obturation of the aperture 93 is decreased and the tolerance increased.
  • Different tolerance ranges are provided by providing alternative holes 63 in the plates 59 and 88 into which a pivot pin 65 may be inserted.
  • the photoelectric cells used are preferably photoresistive, although photovoltaic cells or other photoelectric devices could conceivably be used, and further description is based on the assumption that photoresistive cells are used.
  • the lower housing 2 accommodates a stabilized AC power supply which supplies a tungsten lamp in the lamp house 6, and an electronic assembly consisting of a circuit board 112 mounted in the upper housing which processes the output of the cells 76, 70, 82, 90, and the solenoid 56, the last being controlled by the assembly 112.
  • This assembly comprises a separate power supply comprising a transformer T1, its primary being connected to the stabilized AC supply at 114, 116.
  • the transformer secondary is connected across a bridge rectifier comprising diodes D1-D4, the output of which is connected to a negative lead 118 and a positive lead 120, and is smoothed by capacitor C1.
  • the positive lead 121) feeds two further positive leads 122, 124, through resistors R6, R7, the potentials of both being stabilized by diodes D5, D6 and D7, D8.
  • the resistance of the photoresistive cell 76 is lowered in response to the illumination it receives upon a bottle reaching the inspection station 41, and since it is connected to assembly 112 so as to form part of a potential divider completed by re sistor R1 and preset potentiometer VR1, it controls the bias applied to the base of transistor TR1, which together with TR2, R2, R3 and R41, forms a Schmitt trigger circuit fed from the positive lead 122.
  • Triggering of the circuit by reason of lowering the resistance of cell 76 beyond a level preset by means of VR1 causes TR2 to conduct and a pulse to be trans mitted to an amplifier comprising TR3, R8 and R9 via coupling capacitor C2, from whence the amplified pulse is applied to the base of T114 which forms part of an AND gate comprising TR4 and TRS.
  • the collector of TR4 is fed from the lead 122 via TR5, which conducts only on a suitable bias being applied to its base.
  • the pulse potential developed across R111 passes via R11 to a further amplifier fed from the lead 120 and comprising TR6, TR7, R12, R13, R14 and R15, a network comprising C3, R16 serving 'to maintain a sufficient bias at the base of TR6 to enable it to conduct for a period determined by the values of C3 and R16.
  • Diode D9 prevents the development of a reverse potential across C3.
  • Such a pulse will however be held at TR4, and the solenoid not actuated, if no bias is applied to the base of TR5, the application or otherwise of a bias being determined by that part of the circuit fed from the lead 124.
  • the photoresistive cell 82 is connected to form a potential divider with R18 and either of the two present potentiometers VR2 and VR3 according to the position of switch S1, the divider being used to bias the base of transistor TR8 which together with TR9, R19, R20 and R21 forms a further Schmitt trigger circuit.
  • either VR1 or VR2 is set so that a value of resistance of the cell 82 exactly corresponding to a level of filtered light transmission falling between that of bottles acceptable and that of bottles not acceptable on the ground of color causes TR7 to be biased to exactly that level at which the Schmitt trigger circuit changes state from TR8 conducting to TR9 conducting or vice versa.
  • S1 and the second potentiometer enables an alternative level to be present and selected at will.
  • either one of these potentials if developed may be applied via diode D10, switch S5 and resistance R22 to the base of TRS, causing the latter to conduct and TR4 to pass the pulse developed from cell 76. If S2 is operated to select the potential if any across R20, bottles darker than the selected level will be diverted, and if the potential if any across R21 is selected, bottles lighter than the selected level will be diverted.
  • the photoresistive cells and 70 are connected into similar circuits, comprising respectively TRIO, TR11, R23 26, VR4, S3, D11 and S6, and TRl2, TR13, R27-30, VRS, 54, D12 and S7, the only difference being that no alternative preset potentiometer and associated switch is provided in either case.
  • Switches S5S7 enable any one of the three circuits to be switched out, whilst the diodes Dl0Dl2 prevent interaction between the circuits and form an OR gate.
  • the switch S3 is operative either to divert or not to divert dimensionally acceptable bottles according to whether the potential across R25 or R24 is selected, whilst in the case of the circuit associated with cell 70, the switch S4 is operative either to divert or not to divert bottles with ceramic labels, according to whether the potential across R30 or R29 is selected.
  • the windows 46 are of relatively small size so that the pulse is not transmitted until the bottle is exactly at the inspection station.
