Abstract
Rod-shaped articles such as finished cigarettes are drawn individually from a magazine and are subjected to at least one first test while moving in a first direction in a predetermined orientation (e.g. with the flutes of rotary drums at right angles to their axes), and thereupon to at least a second test while moving in a second direction in a second predetermined orientation (e.g. axially in the form of a file).The first test(s) may involve testing the integrity of the wrapper and/or the density of the ends of each cigarette. The second test(s) may involve optically scanning the external surfaces of the cigarettes, monitoring the density of the fillers of successive cigarettes, and/or weighing the cigarettes. A nozzle may be provided ahead of the first additional testing station to blow away impurities from the external surfaces of the cigarettes prior to the optical scanning test. <IMAGE>
Description
SPECIFICATION
Method and apparatus for ascertaining the condition of rod-shaped articles of the tobacco processing industry
The present invention relates to a method and to an apparatusforascertainingthecondition of rod- shaped articles ofthe tobacco processing industry.
More particularly, the invention relates to improvements in a method andapparatusforsubjecting successive or selected rod-shaped articles of the tobacco processing industry to several tests, such as determining the integrity or absence of integrity of their wrappers; determining the condition (particular lythe density or hardness) ofthetobacco-containing ends of plain orfiltercigarettes, cigarillos or cigars; determining the presence or absence of flaws at the exterior of rod-shaped articles; monitoring the density of the tobacco-orfilter-containing fillers of rod-shaped articles; and weighing the rod-shaped articles.
It is well known to monitorvariouscharacteristics of cigarettes or analogous rod-shaped articles ofthe tobacco processing industry (hereinafter called cigarettes with the understanding, however,thatthe same type of treatment can be carried out in connection with practically all othertypes of tobacco- and/or filter material-containing rod-shaped articles ofthe tobacco processing industry) while the cigarettes are in the process of being mass-produced in a cigarette maker.Such testing of cigarettes is often very reliable andhighlyadvantageous because it renders itpossible to segregate unsatisfactory cigarettes from satisfactory cigarettes before the unsatisfactory cigarettes reach a magazine or a processing machine, such as a packing machine for plain orfiltercigarettes. The defective or unsatisfactory cigarettes are usually introduced into a machine which recovers tobacco for renewed introduction into the distributor of a cigarette maker.
It is often desirable to carry out a relatively simpie or a highly complex examinatioflortesting of cigarettes independently ofthe testing which is performed inthe cigarette maker proper. For example, such independenttesting is often desirable in a laboratory in order to ascertain whether or not the detecting and monitoring units which are installed in the cigarette maker proper operate satisfactorily, i.e., whether or not such units segregate any cigarettes which are sufficiently satisfactoryto warranttheirfurther processing and introduction into soft or hard cigarette packs.Such laboratory tests can be utilized to adjust various potentiometers and/or other sources of reference values which are associated with conventional testing units in a cigarette maker in order to furnish reference values which are relied upon in determination whether or notcertain characteristics of tested cigarettes are satisfactory.
Onefeature of the invention resides in the provision of a method of ascertaining the condition of cigarettes and analogous rod-shaped articles of the tobacco processing industry. The method comprises the steps of accumulating a supply of rod-shaped articles, withdrawing from the supply a succession (e.g., a single file) of rod-shaped articles and advancing the
withdrawn articles along a first path in a first
predetermined orientation, subjecting at least some
articles in the first path to at least one first test, transporting the articles from the first path along a
second path in a second predetermined orientation,
and subjecting at least some articles in the second
path to at least one secondtest.The advancing step
preferably includes moving the articles at least su bsfa ntia Ily at rightangles to their respective axes,
and the transporting step preferably includes moving the articles at least substantially axially.
In orderto ascertain the condition of articles of the type having tubuiarwrappers consisting of cigarette
paper, imitation cork or a similar wrapping material, that test which takes place while the articles move - substantially at right angles to their respective axes can include monitoring the condition ofthewrappers of at least some articles in the respective path. In order to ascertain the condition of the end portions of the articles, that test which takes place while the articles are moved substantially or exactly at right angles to their respective axes preferably includes monitoring at least one end portion of at least some articles in the respective path.
That test which takes place whitethe articles are moved at least substantially axially can include optically scanning the external surfaces of at least some articles inthe respective path. Alternatively, or in addition to the just mentioned test, the test which takes place while the articles are moved substantially axially can include monitoring me density ofthe fillers of at least some articles in the respective path. Still further and in addition to or in lieu ofthe two last mentioned tests, the test which takes place while the articles are moved axially can include weighing at least some articles in the respective path. At least one ofthetwo paths can constitute an at least partially arcuate path.Furhermore, at least one ofthe two paths (particularly the path wherein the articles move axially or substantially axially) is preferably an at least partially straight path.
The method canfurthercomprisethe step of pneumatically cleaning successive articles in one of the two paths. For example,such cleaning step can take place immediately before the articles reach the station where they are optically scanned for the presence of blemishes or other defects in or on their external surfaces.
Anotherfeature of the invention resides in the provision of an apparatus for ascertaining the condition of cigarettes and analogous rod-shaped articles of the tobacco processing industry. The apparatus comprises a magazine or another suitable source of rod-shaped articles, means for advancing from the source a succession of rod-shaped articles along a first path and four maintai ning the articles in first predetermined orientation, first testing means for subjecting at least some articles in the first path to at least one first test, meansfortransporting the articles which have completed their advance along the first path along a discrete second path and for maintaining the articles in a second predetermined orientation, and second testing means for subjecting at least some articles in the second path to at least one second test.
One ofthe advancing and transporting means in cludes means for moving the articles at leastsubstantially at right angles to their respective axes, and the otherofthe advancing and transporting means preferably includes meansfor moving the articles at least substantially axially. The other of the advancing and transporting means can be provided with an elongated flute wherein the articles are moved axially.
The other ofthe advancing andtransporting means can comprise a conveyor andarticle-entraining means on the conveyor. Such conveyor can include an endless flexible element in the form of a belt or chain, and the entraining means is then provided on the flexible element.
The source has an outlet for rod-shaped articles and, in accordance with a presently preferred embodiment ofthe invention, the advancing means comprises a first endless conveyorwhich serves to receive articles that issue from the outlet ofthe source and to move the articles substantially at right angles to their respective axes along an arcuate first portion of the first path, and a second endless conveyor which serves to receive articles from the first endless conveyor and to move the articles substantially at right anglestotheir respective axes along an arcuate second portion ofthefirst path. The first testing means then preferably includes discrete first and second testing devices which are respectively adjacent to and cooperate with the first and second conveyors.Such advancing means can further comprise a third endless conveyor in the form of a rotary drum or the like which servesto move a succession of discrete articles from the outlet to the first conveyor. One of the testing devices which form part of the first testing means can comprise means for monitoring the condition ofthe wrappers of at least some articles in the respective portion of the first path. Another testing device of the first testing means can include means for monitoring one end portion of at least some articles in the respective portion of the first path. The magazine can be provided with a downwardly extending duct which can store a single row of parallel articles and defines the aforementioned outlet.
In accordance with a presently preferred embodiment ofthe invention, the transporting means comprises means for conveying the articles in the form of a file coaxial articles along the second path, and such apparatus preferably further comprises means for feeding successive articles of the file into the second path. The feeding means can comprise an upright duct which receives articles from the second conveyor of the advancing means.Such apparatus can further comprise means for pneumatically cleaning the articles in the second path The cleaning means can comprise a nozzle which is connected to a source of compressedairoranothersuitablegaseousfluidand discharges one or more streams of compressed gas in orderto expel from the exterior of successive rodshaped articles in the second path fragments of tobacco, dust and/or other impurities which may interfere with propertesting ofthe articles during travel along the second path. The second testing means can comprise a device for optically scanning the external surfaces ofatleastsome articles in the second path, a device for monitoring the density of at least some articles in the second path and/or a device for weighing at least some articles in the second path.
The novel features which are considered as charac teristic of the invention are set forth in particular in the appended claims. The improved apparatus itself, however, both as to its construction and its mode of operation,togetherwith additional features and advantagesthereof, will be best understood upon perusal ofthefollowing detailed description of certain specific embodiments with reference to the accompanying drawing.
The single Figure ofthe drawing is a schematic perspective view of an apparatus which embodies one form of the invenbonand wherein the means for advancing rod-shaped articles at right anglesto their respective axes is located ahead ofthe means for transporting the articles axially.
Referring to the drawing in detail, the apparatus which is shown therein comprises a magazine X oran analogous source of parallel rod-shaped articles 4 (hereinafter called cigarettes) having a downwardly extending duct2 containing a single row of parallel cigarettes 4 and defining an outlet which discharges a succession of discrete cigarettes into successive peripheral flutes of a rotary drum-shaped conveyor3 forming part of an advancing means which moves the cigarettes 4 in a first orientation, namely at right angles totheir respective axes.The conveyor 3 is drivento rotate in aclockwisedirection, as viewed in the drawing, and transports a rowofspaced-apart parallel cigarettes 4to a transfer station between the conveyor 3 and a second rotary drum-shaped conveyor 6 which advances the cigarette 4 along an arcuate first portion of a first path past a firsttesting station accommodating a testing device 7 and toward a transfer station between the conveyor 6 and a third rotary drum-shaped conveyor8ofthe advancing means. The conveyor 8 defines an arcuate second portion ofthefirst path wherein the cigarettes 4 are caused to move at right angles to their respective axes and pasta second testing station accommodating a second testing device 9.In the embodiment which is shown in the drawing, the conveyor6 is driven to rotate in a counter-clockwise direction and the conveyor 8 is driven to rotate in a clockwise direction.
A magazine which can be utilized in the apparatus of the present invention to store a supply of parallel cigarettes 4 is disclosed, for example, in commonly owned Germany Pat. No. 955755 or in commonly owned U.S. Pat. No. RE 28,383 to Rudszinat.
The testing device 7 is adjacent to that portion ofthe first path which is defined by the endless drumshaped conveyor 6 and can be the type disclosed in commonly owned U.S. Pat. 3,948,084 to Heitmann et al. This device serves to ascertain the integrity of the tubular wrappers 4a of successive cigarettes 4 on the conveyor 6. The arrangement can be such that the testing device 7 of the first testing means, which further includes the testing device 9, ascertains the presence or absence of holes, frayed ends, open seams and/or combinations of such defects in the wrappers 4a of the adjacent cigarettes. The testing device 9 can be of the type disclosed in U.S. Pat. No.
3,951,267 to Reuland and serves to ascertain the density and/or other characteristics of the adjacent end portions of successive cigarettes 4. For example, the cigarettes 4 may be ofthe type having dense ends, and the testing device 9 can be designed to monitor the densities of the adjacent end portionsofsucces- sive cigarettes 4. The arrangement may be such that the testing device 9 mechanically ascertains the density ofthe adjacent end portions of fillers in successive cigarettes 4 orthatthe device 9 comprises a capacitive or otherwise constructed density monitoring device of any conventional design.
The conveyor 8 of the advancing means delivers successive twice-tested cigarettes 4 into the upper end of a vertical duct 11 which constitutes a means for feeding successive twice-tested cigarettes into the range of a transporting means 16 which is designed to convert the cigarettes 4 into a single file 22 of coaxial cigarettes and to advance such cigarettes axially in the direction indicated by the arrow A.The transporting means 16can comprise an endlessflexible belt or chain conveyor 19which istraned over pulleys or sprocket wheels 17, 18 and is provided with one or more entraining elements in the form of outwardly extending pushers 21 serving to advance successive cigarettes 4from the lower end 12 ofthe duct 11 into the adjacent portion of a horizontal flute 13 in the upper side of an elongated block-shaped guide 14 which is disposed at a level belowthe duct 11. The lower or discharge end 12 ofthe feeding duct 11 admits successive cigarettes into the range of the pushers 21 which transfer successive twice-testedcigarettes 4 from the duct 11 into the flute 13.
The path which is defined by the transporting means 16 is at least substantially straight and can but need not be horizontal.
During travel along such second path, successive cigarettes 4 are subjected to a series of additional tests by testing devices 24,26 and 27 which are adjacent to- the flute 13. It will be notedthatthe block-shaped guide 14 can be assembled of a series of successive spaced-apart sections which alternate with the testing devices 24,26 and 27 as well as with a cleaning device 23 in the form of or including a nozzle. This nozzle is connected to a source 23a of compressed air or another gaseous fluid serving to expel from the external surfaces of successive cigarettes 4 any particles oftobacco, dustand/or otherforeign matter which could interfere with testing by the device 24,26 and/or 27.The cleaning device can be constructed and assembled in a manner as disclosed in commonly owned copending British PatentAppln. No.8410869 by Brand petal. for Method and apparatys for monitoring the diameters of rod-shaped products of the tobacco processing industry". In addition to expelling or removing impurities from the external surfaces of successive cigarettes 4 in the flute 13, the cleaning device 23can also serve asameansfor monitoring the diameters of successive cigarettes in a manner as disclosed in the aforementioned copending patent application of Peter Brand et al.
The testing device 24 ofthe second testing means is located immediately or closely downstream ofthe cleaning device 23 and may be of the type disclosed in commonly owned U.S. Pat. 4,350,170 to Baier. The purpose ofthe testing device 24 is to ascertain the presence or absence of blemishes, improperly applied imprints and/or analogous optically detectable defects on or in the external surface ofthe cigarette 4 which advances from the cleaning device 23 toward the testing device 26. The testing device 24 can further ascertain the presence of holes in thewrappers 4a of cigarettes 4, folds in the wrappers, projecting tobacco ribs, patches of dirt, light-reflecting fragments of adhesive and/or many other defects. Such defects can develop after testing bythe devices 7,9 or even prior to such testing.In the latter instance, sensitivity ofthe testing device 24 is such that it can ascertain defects which cannot be detected by the device 9 and/or 7.
The testing device 26 of the second testing means may be of the type disclosed in the commonly owned
U.S. Pat. 4,024,394to Reuland and may include a density monitoring means which operates with cor puscular radiation.lt is also possible to employ a density monitoring device which operates with X-rays in a manner as disclosed, for example, in commonly owned copending British PatentAppln. 8401681 by
Henning Miller et al. for "Method and apparatus for monitoring and evaluating the density of tobacco stream".
The last testing device 27 of the second testing means is a weighing devicewhich serves to ascertain the mass orweight of successive cigarettes 4. For example, the weighing device 27 may be a laboratory type scale such as that which is manufactured and sold by the assignee ofthe present application under the designation LC.
ltisclearthattheimproved apparatusissusceptible of many additional modifications without departing from the spiritofthe invention. For example, the rather simple vertical gravity ductorfeeding means 11 between the last conveyor8ofthe advancing means andtheflute l3 ofthe transporting means 16 can be replaced with a more sophisticated feeding device, such as a planetary transfer unit of the type disclosed in commonly owned U.S. Pat. No.4,051,947 to
Schumacher. All that counts is to provide some suitable feeding means which can change the orientation of articles during transferfrom the advancing means including the conveyors 3 6,8two to the transport- ing means 16.
It is further possible to provide a suitable computer (shown by broken lines at 28) which can receive and evaluate signals from at least some of the testing devices 7,9,24,26,27 (and 23 ofthe latter is designed to monitorthe diameters ofthe cigarettes 4) and generates suitable output signals which are transmitted to the controls of the cigarette maker, for example, to alter the reference values if the apparatus of the present invention has ascertained that certain characteristics ofthe cigarettes 4 are acceptable. It is assumed herethatthe magazine 1 contains a supply of cigarettes which were segregated from the remaining cigarettes as being defective. The computer 28 can be associated or can include a suitable device 29 which displays the results ofthe various testing, scanning or monitoring operations.
It is also clearthat the various testing devices can be arranged in any other suitable sequence without departing from the spirit ofthe invention. For example, the testing device 9 can precede the testing device 7,thetesting device 27 can precede the testing device 26, and the testing device 24 can followthetesting device 26 or 27.
It is for example also possible to arrange in the transverse conveying region the known weighing and sorting automatic mach ine type LC of the Appl ica nts, having a step conveyorfor its individual stations, and which transfers the rod shaped products by means of a pivotal channel in a lengthwise conveying direction to an X-raytube.
An important advantage ofthe improved method and apparatus isthat it is possible to subject each of a shorteror longer series satisfactory or presumably defective rod-shaped articles of the tobacco processing industryto one or more simple or complex tests independently ofthe testing which takes place during the making of such articles in a cigarette rod making, filtertipping, filter rod making andtor analogous machine.
Another important advantage of the improved method and apparatus is thatthe articles are trans- ported in different orientations so that it can be best associated with and tested by various testing devices.
It should be borne in mind that certain testing devices are capable oftesting rod-shaped articles only, or in a much more satisfactory way, ifthe articles advance therealong by moving axially. On the other hand, certain other testing devices operate more satisfac torily if they can test the a rticles wh i tethe articles are being moved at right angles to their respective axis.
Afurther important advantage of the improved apparatus is its compactness. Such apparatus can be readilysetup in alaboratory, ratherthan in the manufacturing plant proper, and its magazine 1 can be filled with presumably defective rod-shaped articles or with articles which were considered to be satisfactory by the standard testing devices of a cigarette rod making or analogous machine. The advantages ofthe improved apparatus as a means for repeatedly testing cigarettes which were segregated as being defective in a cigarette rod making machine will be readily appreciated. The results of such testing can be utilized to adjustthe cigarette maker in ordertoensure that the makerwill ceaseto eject satisfactory articles or articles which might be veryslightly defective but are stillsatisfactoryforfurtherprocessing,forexample, for introduction into a tipping orpacking machine.
