' * Den foreliggende opfindelse angår et anlæg til fremstilling af bægerformede genstande af den art/ der har et antal med indbyrdes afstand liggende arbejdsstationer til udførelse af en række efter hinanden følgende operatio-5 ner på genstandene, hvilke stationer er forbundet ved hjælp af en kanal til aerodynamisk overføring af genstande fra én arbejdsstation til den næste. Opfindelsen finder navnlig anvendelse ved fremstilling af hylsteragtige genstande, såsom cylindriske todelte kapper eller dåser og lo lommelygtebatterikapper,The present invention relates to a plant for the manufacture of cup-shaped articles of the kind having a number of spaced-apart work stations for performing a series of successive operations on the articles, which stations are connected by means of a channel for aerodynamic transfer of objects from one workstation to the next. The invention is particularly applicable to the manufacture of holster-like objects, such as cylindrical two-piece caps or cans, and lint flashlight battery caps,
Det er velkendt, at sådanne cylindriske genstande almindeligvis udstanses og formes ud fra ved trækning metallisk båndmateriale og derefter trækkes igen en eller flere gange for at reducere diameteren, medens genstandens 15 højde forøges. Principielt bliver genstanden først udstan set af et bånd og trukket nedad gennem en trækkematrice, således at der dannes et cylinderformet bæger, der er relativt stort i diameter og lille i højde. Dette bæger fjernes fra værktøjet og anbringes med sin bund på en passage-2o bane. Bægeret bliver derpå bevæget til en anden arbejdsstation af en luftstrøm, hvor det trækkes igen, og dets diameter reduceres. Sædvanligvis er der ved den anden arbejdsstation sideværts stop med en størrelse, som forhindrer passage af bægeret i dets begyndelsestilstand, men 25 tillader passage, efter at det er blevet trukket igen og dets diameter reduceret. Lignende arrangementer kan findes ved andre mellemliggende stationer, hvor der på bægeret udføres operationer, som reducerer dets diameter. Ved en sidste station bliver flangen tilrettet, og det færdige 3o hylster kan afleveres fra anlægget. Stoppene ved hver af stationerne er forsynet med vakuumåbninger, så at hylstret holdes fast på plads ved stationerne, medens operationen udføres. Efter at bægeret er blevet trukket igen ved enhver af de mellemliggende stationer, kan der findes 35 et løfteorgan til at løfte det tilbage op til en stilling, hvor dets bund er på passagebanen, så at det kan overføres til en efterfølgende station af luftstrøm eller andre passende midler. Et typisk anlæg, der arbejder på denneIt is well known that such cylindrical articles are generally punched and formed from metallic strip material by pulling and then pulled once or more to reduce the diameter while increasing the height of the article. In principle, the object is first constituted by a belt and pulled downwardly through a drawing die to form a cylindrical cup which is relatively large in diameter and small in height. This cup is removed from the tool and placed with its bottom on a passage-20 web. The beaker is then moved to another workstation by an air stream where it is retracted and its diameter reduced. Usually, at the second workstation, there are lateral stops of a size which prevent passage of the beaker in its initial state, but allow passage after it has been retracted and its diameter reduced. Similar arrangements can be found at other intermediate stations where the cup is performed on operations that reduce its diameter. At one last station, the flange is adjusted and the completed 3o casing can be delivered from the plant. The stops at each of the stations are provided with vacuum openings so that the casing is held in place at the stations while the operation is performed. After the cup has been retracted at any of the intermediate stations, a lifting means may be found to lift it back up to a position where its bottom is on the passage path so that it can be transferred to a subsequent station of air flow or other appropriate means. A typical plant working on this

2 ftiåde, er vist og beskrevet i USA patentskrift nr. RE29.645.2 feet, are shown and described in U.S. Patent No. RE29,645.
I nogle tilfælde kan der være tale om, at den bestemte operation, som tilføres ved en arbejdsstation, ikke tjener til at reducere diameteren af bægeret. Eksempelvis 5 kan der' udføres en bestemt operation, hvor et hul dannes i bunden af bægeret, eller sidevæggene af bægeret bliver trukket for at opretholde den samme diameter, men forøge genstandens højde. I disse tilfælde vil den i det ovenfor nævnte patentskrift beskrevne type af begrænsende sidelo stop ikke tjene til at holde bægeret på plads under operationen ved en bestemt arbejdsstation. I så fald skal der følgelig findes mekanisk aktiverede mellemliggende stop, som tidsstyres sammen med virkningen af pressestemplet.In some cases, the particular operation applied at a workstation may not serve to reduce the diameter of the beaker. For example, a particular operation may be performed in which a hole is formed at the bottom of the beaker or the side walls of the beaker are drawn to maintain the same diameter but increase the height of the object. In these cases, the type of limiting lateral stop described in the above-mentioned patent will not serve to hold the cup in place during the operation at a particular workstation. In this case, there must therefore be mechanically activated intermediate stops, which are timed together with the effect of the plunger.
Formålet med den foreliggende opfindelse er at 15 tilvejebringe et anlæg af den indledningsvis angivne art, hvor aerodynamisk overføring af genstandene kan ske, uden at en ændring i genstandenes dimension og mellemliggende mekaniske stop er påkrævet.The object of the present invention is to provide an installation of the kind initially described, in which aerodynamic transfer of the objects can occur without a change in the dimension of the objects and intermediate mechanical stops.
I henhold til den foreliggende opfindelse er kana-2o len til aerodynamisk overføring af genstandene dannet af et antal under indbyrdes vinkler beliggende kanalsegmenter, som danner indre hjørner med afrundede overflader ved deres forbindelsessteder, hvor arbejdsstationerne er beliggende ved forbindelsesstederne, organer til at holde genstandene imod 25 et indre hjørne under operationen ved den pågældende arbejdsstation og organer til at føre genstandene fremad fra station til station efter hver operation.According to the present invention, the channel 2 for aerodynamically transmitting the articles is formed by a plurality of inter-angular channel segments which form inner corners with rounded surfaces at their connection points where the workstations are located at the connection points, means for holding the objects against 25 shows an internal corner during the operation at the workstation concerned and means for moving the objects forward from station to station after each operation.
Som det vil fremgå, tilvejebringer den foreliggende opfindelse midler til at holde bægeret nøjagtigt på 3o plads ved hver arbejdsstation uden hensyn til, om anlægget anvendes til emner med en afvigende størrelse eller diameter.As will be seen, the present invention provides means for holding the cup accurately in position at each work station regardless of whether the system is used for items of varying size or diameter.
Som følge heraf kan fremstillingsoperationer,såsom huldannelse eller vægtrækning, udføres uden behov for komplicerede mekaniske holdemekanismer.As a result, manufacturing operations, such as hole forming or weight drawing, can be performed without the need for complicated mechanical holding mechanisms.
35 I en udførelsesform ifølge opfindelsen indbefatter organerne til at føre genstandene fremad fra station til station efter hver operation organer i forbindelse med den sidste arbejdsstation til at aflevere genstanden aksialt iIn one embodiment of the invention, the means for moving the objects forward from station to station after each operation includes means in connection with the last work station for delivering the object axially in

3 forhold til denne. Disse organer ved den sidste station kån være i form af et bevægeligt stop, som tillader dåsen at bevæges aksialt af tyngdekraften ned under passagebanen og transporteres til efterfølgende fremstillingsstation.3 relation to this. These bodies at the last station may be in the form of a movable stop which allows the can to be moved axially by gravity down the passage path and transported to subsequent manufacturing station.
5 Ved en foretrukken udførelsesform som angivet i krav 11 trækker en første arbejdsstation et bæger ud fra et metalemne, og en anden arbejdsstation trækker igen bægeret for at reducere dets diameter. Bægeret føres derefter til en formningsstation, en huldannelsesstation og afrette- eller endelo stationer. Bægeret overføres mellem arbejdsstationerne af kanalsegmenter .In a preferred embodiment as claimed in claim 11, a first workstation pulls out a beaker from a metal blank, and a second workstation again pulls the cup to reduce its diameter. The cup is then conveyed to a forming station, a hole forming station, and erection or end stations. The beaker is transmitted between the workstations by channel segments.
Endearbejdsstationen og dens tilknyttede dele kan ifølge opfindelsen hensigtsmæssigt være udført som angivet i krav 13, og organerne, som tillader genstanden at falde ned 15 under passagebanen, kan ifølge opfindelsen hensigtsmæssigt være udformet som angivet i krav 14.The end work station and its associated parts may according to the invention be suitably designed as claimed in claim 13, and the means which allow the article to fall down 15 during the passage path may according to the invention be suitably designed as claimed in claim 14.
De forskellige arbejdsstationer kan være anbragt på lineær måde, således at den første station findes ved en forreste ende og endestationen ved en bageste ende. Ifølge opfindelsen kan 2o orienteringen af stationerne imidlertid være en sådan,at den anden station og endestationen er beliggende umiddelbart op til hinanden, idet dette kan være ønskeligt af design- og pladshensyn.The various workstations may be arranged in a linear fashion such that the first station is located at a front end and the end station at a rear end. However, according to the invention, the orientation of the stations may be such that the second station and the end station are located adjacent to each other, which may be desirable for design and space purposes.
Opfindelsen skal herefter forklares nærmere under henvisning til tegningen, hvor 25 fig. 1 viser et brudstykkevist skemati'sk-perspekti- visk billede af en udførelsesform for et aerodynamisk overføringssystem ifølge den foreliggende opfindelse, fig. 2 et brudstykkevist skematisk billede ovenfra 3o af et fremadskridende arbejdende fremstil lingsværktøj med fire udgange, som anvender det aerodynamiske overføringssystem ifølge den foreliggende opfindelse, fig. 3 et brudstykkevist forstørret billede oven-35 fra af en enkelt bearbejdningsbane, som an vender det aerodynamiske overføringssystem ifølge den foreliggende opfindelse, og fig. 4 et brudstykkevist tværsnit efter linien 4-4The invention will now be explained in more detail with reference to the drawing, in which FIG. 1 is a fragmentary schematic perspective view of one embodiment of an aerodynamic transmission system of the present invention; FIG. 2 is a fragmentary schematic top view of a progressive four output manufacturing tool utilizing the aerodynamic transmission system of the present invention; FIG. 3 is a fragmentary enlarged top view of a single machining path using the aerodynamic transmission system of the present invention; and FIG. 4 is a fragmentary cross-section along line 4-4

Den foreliggende opfindelse er beskrevet og vist i forbindelse med fremadskridende arbejdende bearbejdningsapparatur vist generelt ved 1 til fremstilling af en kappe- eller bægeragtig genstand, såsom et dåselegeme eller en batterikappe. I den specifikke beskrevne og i fig. 2 5 skematisk viste udførelsesform anvender bearbejdningsapparaturet 1 fire bearbejdningsbaner 2. Det vil imidlertid forstås, at bearbejdningsbanerne er identiske i konstruktion og virkmåde. Kun én af banerne vist generelt ved 3 vil følgelig blive beskrevet.The present invention is described and shown in conjunction with progressive working processing apparatus shown generally at 1 for the manufacture of a sheath or cup-like object, such as a can body or a battery sheath. In the specific described and in FIG. In a schematically illustrated embodiment, the processing apparatus 1 uses four processing paths 2. However, it will be understood that the processing paths are identical in construction and operation. Accordingly, only one of the lanes generally shown at 3 will be described.
lo I den specifikke beskrevne udførelsesform indbe fatter- hver bearbejdningsbane 2 fem arbejdsstationer omfattende en stanse- og trækkestation 4, en gentrækkesta-tion 5, en bunddannelsesstation 6, en huldannelsesstation 7 og en afretningsstation 8. Det vil imidlertid forstås, at 15 et hvilket som helst antal efter hinanden følgende arbejdsstationer kan tilvejebringes for en bestemt anvendelse. Endvidere er detaljerne ved udstansematricerne og gen-trækkematricerne såvel som de respektive stempler ikke vist, eftersom disse træk er konventionelle og velkendte 2o og forstås af fagmanden.In the specific embodiment described, each processing path 2 includes five workstations comprising a punching and pulling station 4, a gene pulling station 5, a bottom forming station 6, a hole forming station 7 and a straightening station 8. However, it will be understood that any number of consecutive workstations can be provided for a particular application. Furthermore, the details of the punching and retraction matrices as well as the respective pistons are not shown, since these features are conventional and well known and understood by those skilled in the art.
I den første station eller stanse- og trækkestationen 4 udstanses et cirkulært emne 9 af en plade af metalmateriale. Som det er i og for sig velkendt, kan plademateriale lo tilføres fra en ikke vist materialerulle og be-25 væges fremad i retning af pilen 11 efter hver stanseoperation.In the first station or the punching and pulling station 4, a circular blank 9 is punched by a sheet of metal material. As is well known in the art, sheet material 10 may be supplied from a roll of material not shown and moved forward in the direction of arrow 11 after each punching operation.
Efter stanseoperationen bliver det cirkulære emne 9, der er vist punkteret i fig. 1, trukket ved hjælp af et matriceorgan 12 i stanse- og trækkestationen 4 for at 3o danne et relativt bredt cylindrisk bæger 13a med lille dybde. Efter at bægeret 13a er trukket, bliver det aftrukket nedad ved hjælp af ikke viste aftrækkeorganer og ender i stillingen vist i fig. 4, hvor bunden af bægeret hviler på en vandret beliggende stillestående passagebane 14.After the punching operation, the circular blank 9 shown in FIG. 1, drawn by means of a die 12 in the punching and pulling station 4 to form a relatively wide cylindrical cup 13a of small depth. After the cup 13a is pulled, it is pulled downward by means of the pull-off means not shown and ends in the position shown in FIG. 4, wherein the bottom of the cup rests on a horizontally positioned stationary passage path 14.
35 Det vil ses, at passagebanen 14 danner den nederste overflade af en rendeformet kanal vist generelt ved 15, som tjener til at lede bægrene gennem efter hinanden følgende arbejdsstationer i bearbejdningsanlægget. Kanalen 15 5It will be seen that the passage path 14 forms the lower surface of a gutter-shaped channel, generally shown at 15, which serves to guide the cups through successive workstations in the processing plant. Channels 15 5

indbefatter et første lige kanals'egment 16, som strækker' sig fra stanse- og trækkestationen 4 til gentrækkestatio-nen 5. Bægeret 13a føres fremad gennem det første kanalsegment 16 ved hjælp af en luftstrøm, som er parallel med ka-5 nalsegmentet og frembringes af en luftdyse 17, der er beliggende opstrøms i forhold til stanse- og trækkestationen 4. Trykluft synkroniseret med operationen af stanse- og trækkeværktøjet kan tilføres luftdysen 17 i retning af pilen 18 fra en ikke vist kilde.includes a first straight channel segment 16 extending from the punch and pull station 4 to the gene pull station 5. The beaker 13a is advanced through the first channel segment 16 by an air flow parallel to the channel segment and produced of an air nozzle 17 located upstream of the punching and pulling station 4. Compressed air synchronized with the operation of the punching and pulling tool can be supplied to the air nozzle 17 in the direction of the arrow 18 from a source not shown.
lo Ved gentrækkestationen 5 drejer kanalen 15 til højre ved hjælp af et lige andet kanalsegment 19, der er orienteret vinkelret på det første kanalsegment 16.Som det bedst fremgår af fig. 1 og 3,danner forbindelsesstedet af kanalsegmenterne 16 og 19 et i hovedsagen afrundet indre hjørne 15 2o med i det væsentlige samme diameter som den ydre diameter af det trukne bæger 13a. Det vil ses, at krumningsradius for det afrundede hjørne 2o er tilstrækkelig til at sikre overflade-mod-overfladekontakt med i det mindste ca. en fjerdedel af den ydre overflade af det trukne bæger 13a.10 At the gene pull station 5, the channel 15 is turned to the right by a straight second channel segment 19 oriented perpendicular to the first channel segment 16. As best seen in FIG. 1 and 3, the connection site of the channel segments 16 and 19 forms a substantially rounded inner corner 15o of substantially the same diameter as the outer diameter of the drawn cup 13a. It will be seen that the radius of curvature of the rounded corner 20o is sufficient to ensure surface-to-surface contact with at least approx. a quarter of the outer surface of the drawn cup 13a.
2o Bægeret 13a skubbes ind i hjørnet 2o af kraften fra luftstrømmen, som afgives fra luftdysen 17, der er korrekt tidsstyret i forhold til stanse-,trække- og gentrækkeope-rationerne ved hjælp af ikke viste organer. Bægeret 13a kan holdes tæt ind i hjørnet 2o for nøjagtigt at placere 25 bægeret under gentrækkeoperationen ved hjælp af en eller flere vakuumåbninger, hvoraf én er vist ved 21, som er placeret i midten af krumningen af det afrundede hjørne 2o og tjener til at trække bægeret imod den afrundede hjørneoverflade. Vakuumet, som frembringes af vakuumåbningen, 3o bliver synkroniseret med bearbejdningsoperationen for at holde og frigive det trukne bæger 13a i det korrekte tidsrum.2o The cup 13a is pushed into the corner 2o by the force of the air flow delivered from the air nozzle 17 which is properly timed relative to the punching, pulling and repeating operations by means not shown. The cup 13a can be held tightly into the corner 20o to accurately place the cup during the gene pull operation by one or more vacuum openings, one of which is shown at 21, which is located in the center of the curvature of the rounded corner 20o and serves to pull the cup. against the rounded corner surface. The vacuum produced by the vacuum opening 30 is synchronized with the machining operation to hold and release the drawn cup 13a for the correct period of time.
Under gentrækkeoperationen trækkes bægeret 13a til en langstrakt og reduceret diametertilstand angivet ved 35 13b. Efter gentrækkeoperationen vil bunden af bægeret 13b væ re placeret under passagebanen 14. På dette tidspunkt træder en udløfteskive 22, som påvirkes af et kamskive-fjedereller lufttrykorgan (ikke vist) i funktion for at løfteDuring the gene pulling operation, the beaker 13a is pulled to an elongated and reduced diameter state indicated by 13b. After the gene pull operation, the bottom of the beaker 13b will be located below the passage path 14. At this point, a venting disc 22, which is actuated by a cam washer or air pressure means (not shown), functions to lift

6 det gentrukne bæger 13b, således*at bunden af bægeret igen kommer i plan med passagebanen 14. Denne konstruktion er konventionel og velkendt indenfor den pågældende teknik.6, the re-engraved cup 13b so that the bottom of the cup comes into alignment with the passage path 14. This construction is conventional and well known in the art.
På dette tidspunkt tilføres trykluft til en luftdy-5 se 23 beliggende koaksialt med det andet kanalsegment 19 ved hjørnet 2o for at skubbe eller fremføre det gentrukne bæger 13b gennem det andet kanalsegment hen mod bunddannelsesstationen 6.At this point, compressed air is supplied to an air nozzle 23 located coaxially with the second channel segment 19 at the corner 20 to push or advance the retracted beaker 13b through the second channel segment toward the bottom formation station 6.
Som det bedst fremgår af fig. 1 og 3, er bunddannel-lo sesstationen 6 beliggende ved forbindelsesstedet for det andet kanalsegment 19 og et lige tredie kanalsegment 23.As best seen in FIG. 1 and 3, the bottom forming station 6 is located at the junction of the second channel segment 19 and a straight third channel segment 23.
Det tredie kanalsegment 23 er orienteret vinkelret på det andet kanalsegment 19 og strækker sig til højre derfra.The third channel segment 23 is oriented perpendicular to the second channel segment 19 and extends to the right thereof.
Det vil ses, at forbindelsesstedet for disse, kanalsegmenter 15 danner et afrundet indre hjørne 24 med i det væsentlige samme krumningsradius som den ydre krumningsradius af det gentrukne bæger 13b. I almindelighed vil det afrundede hjørne 24 være udformet således, at det tilvejebringer over-flade-mod-overfladekontakt med i det mindste en fjerdedel 2o af den ydre cylindriske overflade af det gentrukne bæger.It will be seen that the junction site of these channel segments 15 forms a rounded inner corner 24 having substantially the same radius of curvature as the outer radius of curvature of the retracted cup 13b. Generally, the rounded corner 24 will be configured to provide surface-to-surface contact with at least a quarter of the outer cylindrical surface of the recycled cup.
Bægeret bliver nøjagtigt placeret og fastholdt på plads imod det afrundede hjørne 24 ved hjælp af et vakuum, som frembringes af en vakuumåbning 25, der er beliggende ved midten af krumningen af hjørnet 24. I almindelighed 25 vil vakuumet, som frembringes af vakuumåbningen 25, blive tidsstyret for at holde bægeret på plads, indtil bunddannelsesværktøjet vist generelt ved 26 i fig. 4 træder ind i bægeret. Ved denne arbejdsstation dannes en bund i bægeret, hvilket resulterer i bægergenstanden 13c. Efter bund-3o dannelsesoperationen kan bægeret 13c bevæges fremad fra stationen 6 til huldannelsessektionen 7 af en luftstrøm, der udsendes af en luftdyse 27 beliggende i det afrundede hjørne 24 og rettet mod den næste arbejdsstation. Det vil forstås, at luftstrømmen, som udsendes af luftdysen 27, er 35 tidsstyret i forhold til operationen af bunddannelsesværktø jet 26.The cup is precisely positioned and held in place against the rounded corner 24 by a vacuum produced by a vacuum opening 25 located at the center of the curvature of corner 24. In general, the vacuum produced by the vacuum opening 25 will be time controlled to hold the beaker in place until the bottom forming tool shown generally at 26 in FIG. 4 enters the cup. At this workstation, a bottom is formed in the cup, which results in the cup article 13c. After the bottom 30 forming operation, the beaker 13c can be moved forward from the station 6 to the hollow section 7 of an air stream emitted by an air nozzle 27 located in the rounded corner 24 and directed to the next work station. It will be understood that the air flow emitted by the air nozzle 27 is time-controlled relative to the operation of the bottom forming tool 26.
Et lige fjerde kanalsegment 28 forbinder huldannelsesstationen 7 med afrettestationen 8. Kanalsegmentet 7A straight fourth channel segment 28 connects the hole forming station 7 with the execution station 8. The channel segment 7
DK 151690BDK 151690B
28 er orienteret vinkelret på kanalsegmentet 23 og strækker sig til venstre derfra, så der dannes et afrundet indre hjørne 29 beliggende ved huldannelsesstationen 7. Hjørnet 29 er udformet til at holde bægeret 13c tæt og nøjagtigt 5 på plads under operationen af en huldannelsesmatrice 3o, som danner et hul 31 i bunden af bægeret for at danne en hulbægergenstand 13d. Under huldannelsesoperationen kan bægeret fastholdes på plads ved hjælp af et vakuum, som skabes gennem en vakuumåbning 32 beliggende ved midten af lo krumningen af det afrundede hjørne 29,se fig, 3. Frembringelsen af vakuumet i tilknytning til denne vakuumåbning vil være tidsstyret med operationen af huldannelsesmatricen 3o.28 is oriented perpendicular to the channel segment 23 and extends to the left thereof to form a rounded inner corner 29 located at the hollow forming station 7. The corner 29 is designed to hold the cup 13c tightly and precisely 5 in place during the operation of a hollow forming matrix 30 which forming a hole 31 at the bottom of the cup to form a hollow cup article 13d. During the hole-forming operation, the cup may be held in place by a vacuum created through a vacuum opening 32 located at the center of the curvature of the rounded corner 29, see Fig. 3. The generation of the vacuum associated with this vacuum opening will be timed with the operation hole forming matrix 3o.
Efter huldannelsesoperationen kan bægeret 13d bevæges gennem det fjerde kanalsegment 28 til afrettestatio-15 nen 8 ved hjælp af en luftstrøm, som afgives fra en luftdyse 33 beliggende ved hjørnet 29. Operationen af luftdysen 33 vil være tidsstyret med operationen af huldannelsesmatricen 3o.After the hole-forming operation, the beaker 13d can be moved through the fourth channel segment 28 to the discharge station 8 by means of an air stream which is delivered from an air nozzle 33 located at the corner 29. The operation of the air nozzle 33 will be timed with the operation of the hole-forming matrix 30.
Resten af konstruktionen i forbindelse med huldan-2o nelsesstationen 7 er af konventionel' udførelse.The remainder of the construction associated with the hollow forming station 7 is of conventional design.
Den sidste station,afretterstationen 8,indbefatter et stoporgan 34 med en cylindrisk flade beliggende midt for ved enden af kanalsegmentet 28 sammen med en afrundet kanalvægdel 35, der er udformet til at ligge an mod en del af den ydre cylin-25 driske overflade af bægergenstanden, som modtages fra arbejdsstationen 7. En vakuumåbning 36 drives i synkronisme med afretteværktøj et 37 for at holde bægeret fast imod stoporganet, medens afretningsværktøjet bevæger sig ned i bægeret. Efter at værktøjet er ført ind i bægeret, trækkes 3o stoporganet 34 tilbage i retning af pilen 38, så at flangen 39 på bægeret 13d kan gå fri af kanalvægdelen 35 for at tillade bægeret at falde nedad aksialt i forhold til sig selv til stillingen vist punkteret i fig. 4, så at flangen kan fjernes. Dette resulterer i, at det endelige bæger 13e 35 på grund af tyngdekraften falder ned på en transportør 4o, hvormed den færdige genstand kan fjernes fra anlægget.The last station, the eraser station 8, includes a stop member 34 with a cylindrical surface located at the center of the end of the channel segment 28 along with a rounded channel wall portion 35 formed to abut a portion of the outer cylindrical surface of the beaker article. received from the workstation 7. A vacuum aperture 36 is synchronously operated with alignment tool 37 to hold the beaker against the stop member as the alignment tool moves down the beaker. After the tool is inserted into the beaker, the stop member 34 is retracted in the direction of the arrow 38 so that the flange 39 on the beaker 13d can be detached from the channel wall portion 35 to allow the beaker to fall down axially with itself to the position shown punctured. in FIG. 4 so that the flange can be removed. This results in the final beaker 13e 35 falling due to gravity onto a conveyor 4o, whereby the finished article can be removed from the plant.
Selv om kun funktionen af en enkelt bearbejdningsbane er blevet beskrevet af hensyn til den eksempeltdseAlthough only the function of a single machining path has been described for the sake of the exemplary

8 forklaring, vil det forstås, at' alle bearbejdningsbaner 2 kan arbejde samtidigt for at udføre de beskrevne operationer .8, it will be understood that all machining paths 2 can work simultaneously to perform the operations described.
Medens hosliggende kanalsegmenter i den eksempelvise illustration er orienteret tilnærmelsesvis vinkelret på hinanden, vil det forstås, at de kan være anbragt under en hvilken som helst ønsket vinkel med hinanden. Som vist punkteret i fig. 2 kan eksempelvis vinklen mellem det første kanalsegment 16 og det andet kanalsegment 19 være større end 90°, hvilket giver kanalen 15 en zig-zagform. Dette kan være særlig nyttigt, når diameteren af bægeret skal reduceres under operationen ved den pågældende arbejdsstation. I dette tilfælde lettes positioneringen af bægeret af den indsnævrede indgangsvej til det efterfølgende kanalsegment. Efter at diameteren af genstanden er blevet reduceret, kan den let passere ind i kanalsegmentet 19 til den næste arbejdsstation.While adjacent channel segments in the exemplary illustration are oriented approximately perpendicular to each other, it will be appreciated that they may be disposed at any desired angle with each other. As shown punctured in FIG. 2, for example, the angle between the first channel segment 16 and the second channel segment 19 may be greater than 90 °, giving the channel 15 a zig-zag shape. This can be particularly useful when reducing the diameter of the beaker during surgery at that workstation. In this case, the positioning of the beaker is facilitated by the narrowed entry path to the subsequent channel segment. After the diameter of the article has been reduced, it can easily pass into the channel segment 19 to the next workstation.
