- ABSTRACT Apparatus and method for sorting foreign closures from a stream of closures being fed into a capping machine A light source is positioned at an acute angle with respect to the horizontal plane defined by the top panel of a metal closure. A light sensing unit is positioned at an angle with respect to the horizontal plane less than the angle of spectral reflection of the light from the light source. It has been found that each of a plurality of metal closures has unique light-scattering properties which may be measured by the light sensing unit positioned off of the angle of reflection of the light source.
- a level may be established for each of the closures.
- the rejection mechanism most frequently takes the form of a puff of compressed air to blow foreign closures from a line of closures being fed into a capping machine.
- the apparatus further includes a series of filters positioned over the light source to reduce the amount of light to an intensity level to which the light sensing unit is responsive.
- the effect in such a case, is alsoto cause amajamming of the capping machine, which would have been set up to accept only the closure for the currentcapping operation.
- foreign .caps are detected only by a human operator standingby the cap feed line and visually observing foreign caps and removing :them from the feed line. This, of course, is .an inefficient and expensive process, since the human operator is subject to error and may on occasion miss the presence .of foreign caps.
- the present invention presents an apparatus which automatically sorts caps and rejects any foreign caps from the line feeding the capping machine.
- a light source is positioned at an acute angle with respectto a horizontal plane designed by the top panel of a closure
- a light-sensitive detection unit is then positioned opposite the light source at an angle less than the angle of spectral reflection of the light from the light source.
- Individual closures are then placed into the path of the light beam andtheir scattering properties are measured by the light sensitive detection unit.
- an electronic logic unit may be set to reject closures which give scattered light values 5 above or below the unique preset level.
- FIG. 1 is an elevational view of the apparatusof the present invention as his used todetermine the unique llightt-scattering properties of v eachclosure;
- FIG. 2 is a plan view of tthe apparatus of the present invention as it would be utilized in conjunction with the feeding of a series of closures to a capping machine.
- a source of lightt 10 is positioned over a stationary flat surface 12 at an acute angle by suitable sup- 0 port means (not shown).
- a light sensing unit 14 is also positioned over the fiat surface 12 at an acute angle less than the spectral angle of reflection of light from the light source 10 by the same support means used to carry the light source 1010.
- the light source 10 is positioned at an angle of with respect to the plane of the flat surface 12.
- the sensing unit 14 is positioned at an angle of 30 with respect to the flat surface 12.
- the light source 10 is made up of a c number of components.
- a 12 volt incandescent lamp 16 is held in place in a suitable lamp holder 18.
- a lens tube 20 is telescopingly engaged over the lamp holder 18.
- the lens tube 20 serves to carry a piano-convex lens 22 which is used to focus the light emanating from the incandescentlamp 16.
- a series of three filters 24, 25 and 26 are positioned near the end of the lens tube 20.
- the filter 24 is a Roscolene No. 871; the filter 25 is a Roscolene 874; and the filtter 26 is a Roscolene No. 878.
- the filters 24, 25 and 26 are all manufactured by Rosco Laboratories, Inc., Port Chester, NY. The net effect of the filters 24, 25 and 26 is to filter out all the light emanating from the incandescent lamp 16 except that light falling within the 4800 to 4600 Angstrom wavelength range. Th This light is green in color. The particular color oof light transmitted by the light source10 is not critical for proper 0 operation of this invention.
- the filters 24, 25 and 26 serve merely to reduce the intensity of light issuing from the light source 10 to a level which is acceptable to a photo transistor 28 mounted within the light sensing unit 14.
- the light sensing unit 14 itself is also made up of several component parts.
- a support tube 30 forms the major framework for the sensing unit 14.
- the phe photo transistor 28 which is an LS-6OO photo transistor manufactured by the General Sensors Corporation of Athens, Texas.
- the photo transistor 28 is of the type whose resistance varies s a function of the amount of light incident on it.
- a double convex lens 32 and a plano-convex lens 34 which are used to focus incoming light on the photo transistor 28.
- an infrared filter 36 is mounted at the entrance to the mounting tube 30. The purpose of the infraredfilter 36 is to filter out all wavelengths above 7500 Angstroms. This was found necessary because of the effect oof various ambient light sources on the sensitivity and discrimination of the photo transistor 28.
- the output of the photo transistor 28 is through a suitable electric wiring network 38 8 into an ohmeter 40 in the embodiment shown in FIG. 1.
- the configuration shown in FIG. 1 may beused to measure the apprisque light-scattering properties of a plurality of cllosures 42 for use in determining a level of acceptance or rejection when inspecting a plurality of moving closures 42. I have found that,
- the characteristics of the photo transistor 28 are such that its resistance varies dependingon the amount of light incident upon it. Because of the unique light-scattering properties of each specific closure, the resistance of the photo transistor 28 will be different for different types of closures. The results obtained for eleven different types of closures are shown in Tables 1 and 2.
- Sample Nos. 1 and 7 These closures are identical except for the type of paint on the top of the closure. It is believed that the scattering effect is a function of the type of paint and its color on the top of each closure. It should also be noted that Samples 2, 8, 10 and l l are also identical in size and configuration, but are unlike in the type of paint placed on the top of the closure. It will be noted from Table 2 that closures 9 and 11 gave identical results seeming to contradict the unique light-scattering properties attributed to each specific closure. However, closure 9 was an unpainted closure having a brushed aluminum top. The direction in which the burnishing marks appear on the top of closure No. 9 appear to have a significant effect on the light-scattering properties of such a closure. Therefore, this apparatus is not usable with respect to such closures but may be used with any painted closure to discriminate and select one specific closure from other unlike closures if the top surfaces of the closures are paintedto present a uniform reflecting surface.
- FIG. 2 a plurality of supposedly identical closures 42 are conveyed toward a capping machine in the direction shown by the arrow by a suitable conveying means 44.
- the conveying means 44 may be a belt-type conveyor or may be an inclined chute down which the closures 42 slide.

- a light source 10 and a sensing unit 14 as shown in FIG. 1, which are supported from the conveying means 44 by suitable support brackets 46 and 47.
- An elevational view of FIG. 2 would show a configuration of the light source 10 and the sensing unit 14 as identical to that shown in FIG. 1, with the closures passing under the two units 10 and 14 with their top surface essentially parallel to the conveying means 44.

- the ohmeter 40 has been replaced by a logic and discrimination unit 48 which receives the output from the photo transistor28 through the electrical wiring network 38.
- the logic and discrimination unit 48 is of the type well known in the electronic arts which will give no output so long as the input furnished through the electrical wiring network 38 remains within a specified preset value.
- the preset value is determined by the resistance caused by light scattering of the specific closure which is to be fed into the capping machine. Any foreign or unlike closures which may be transported by the conveying means 44 will cause the photo transistor 28 to give an output different than that preset in the logic and discrimination unit 48. Should this occur, an output from the logic and discrimination unit 48 will be transferred by electrical wiring means 50 to a rejection means 52.
- the rejection means 52 comprises a normally closed air solenoid valve 53 and a directional nozzle 56 connected to an output port of the solenoid valve 53.
- the rejection means 52 could take the form of a reciprocating rod, a swinging gate or similar device suitable for removing an individual unlike closure 42 from the stream of closures 42.
- Air under pressure is furnished through a pipe 54 to the solenoid valve 53.
- the solenoid valve 53 Upon signal from the logic and discrimination unit 48, the solenoid valve 53 will open, allowing compressed air to flow outward through the nozzle 56.
- the blastof high-pressure air emanating from the nozzle 56 will blowa foreign closure 42 from the conveying means 44 and prevent its entry into the capping machine and subsequent jamming of the capping machine.

- This invention generally relates to the sorting of closures for containers.
