Abstract
Description
Oppfinnelsen angår en anordning for en papirkuttemaskin, The invention relates to a device for a paper cutting machine,
som definert i den beskrivende delen av patentkrav 1. as defined in the descriptive part of patent claim 1.
Det vanlige for papirkuttemaskiner er at arkene overlapper hverandre på veien til ei saralekasse. Et problem ved kutting ved høye hastigheter er å bremse arkene tilstrekkelig til at framkantene ikke skades. For å oppnå dette må arkene overlappe hverandre og når en går opp i hastighet nås en grense hvor overlappingen er nær 100 % og maksimum overlap-pingshastighet når 76.2-106.7 m/min. Høy hastighet forårsaker også problemer med luft i papiransamlingen som gjør det vanskelig å håndtere papirbunkene og vanskelig å oppnå høy kvali-tet. It is common for paper cutting machines that the sheets overlap each other on the way to a paper box. A problem when cutting at high speeds is slowing down the sheets sufficiently so that the leading edges are not damaged. To achieve this, the sheets must overlap each other and when speed increases, a limit is reached where the overlap is close to 100% and the maximum overlap speed reaches 76.2-106.7 m/min. High speed also causes problems with air in the paper accumulation, which makes it difficult to handle the stacks of paper and difficult to achieve high quality.
Overlappingsoperasjonen utføres vanligvis v.h.a. båndsys-temer med henholdsvis høy og lav hastighet. Hastigheten på det ledende arket senkes ved at det mates på båndet med lav hastighet v.h.a. et middel slik som en stopperulle. Et eksempel på en slik overlappingsprosess med stopperulle er vist i U.S. Patent No. 3 554 534, hvor en nedbøyningsrulle er plassert oppstrøms for stopperullen for å ta unna haleenden på arkene som strømmer til båndet med lav hastighet, fra veien til det neste påfølgene arket levert av båndet med høy hastighet. The overlapping operation is usually performed by tape systems with respectively high and low speed. The speed of the conductive sheet is lowered by feeding it onto the belt at a low speed, i.e. a means such as a stopper roller. An example of such a stopper roller lapping process is shown in U.S. Pat. Patent No. 3,554,534, where a deflection roller is located upstream of the stopper roller to remove the tail end of the sheets flowing to the low speed belt from the path of the next succeeding sheet delivered by the high speed belt.
Et liknende apparat er kjent fra DE-AS 1.561.728 som beskriver et arktransporterende apparat som omfatter en brem-seinnretning som er plassert mellom leveringsenden av et transportbånd og en oppsamlingssone. Bremseinnretningen omfatter en nedre bremserulle og en øvre oscillerende rulle som sammen vil danne en klemspalte og utøve et hardt "napp" for bremsing av arket. Den oscillerende rullen er drevet slik at arket bare blir "nappet" ved sin bakerste del. Selv om apparatet tillater flere ark å passere, vil overlappingen ikke skje ved nedbremsingen. Overlappete par blir ført fram, men de representerer atskilte stabler med to ark som er skåret fra mer enn en papirhane i arkmaskinen. Slik vil arkene være i overlappet stilling allerede når de kommer til bremsesonen, og umiddelbart etter bremsing blir de ført videre med samme fart som bremserullen. Bruken av hardt "napp" som bremsemiddel er en ulempe pga. tendens til å sette merke på arkene, og det blir ikke kompensert for tykkelsesvariasjoner på tvers av arkene. A similar device is known from DE-AS 1,561,728 which describes a sheet transporting device comprising a braking device which is placed between the delivery end of a conveyor belt and a collection zone. The braking device comprises a lower brake roller and an upper oscillating roller which together will form a clamping gap and exert a hard "nip" for braking the sheet. The oscillating roller is driven so that the sheet is only "nipped" at its rear part. Although the device allows several sheets to pass, the overlapping will not occur during the deceleration. Overlapped pairs are displayed, but they represent separate stacks of two sheets cut from more than one tap in the sheet machine. In this way, the sheets will already be in an overlapped position when they reach the braking zone, and immediately after braking they will be carried forward at the same speed as the brake roller. The use of a hard "pacifier" as a brake is a disadvantage because tend to mark the sheets, and thickness variations across the sheets are not compensated for.
DE-AS 2.841.658 beskriver også et apparat og en fram-gangsmåte for nedbremsing av ark. Apparatet baserer seg på vakuum for nedbremsing av arkene, mens en roterende børste er anbragt for å slå ned bakre del av arkene for at en vakuum-stang skal kunne gripe arket ved slepekanten og føre det inn i oppsamlingssonen. Børsten er kun et organ for å slå arket ned og deltar ikke her i bremsingen. Forskjellige ulemper oppstår når vakuum alene brukes for nedbremsing av arkene. Vakuum virker ikke tilfredsstillende ved bruk av flere papirbaner og heller ikke ved bruk av store hastigheter pga. den store tregheten til arkene. Ved flere papirbaner virker vakuum mer effektivt på bunn-arkene enn på topp-arkene, og tregheten til topp-arkene vil sende disse gjennom med større fart. På denne måten oppstår et fenomen kalt "shuffling" som resulterer i at topp-arket føres lenger enn det nedre arket. Dette blir kritisk ved høye hastigheter. DE-AS 2,841,658 also describes an apparatus and a method for slowing down sheets. The apparatus is based on vacuum to slow down the sheets, while a rotating brush is arranged to knock down the rear part of the sheets so that a vacuum rod can grab the sheet at the trailing edge and lead it into the collection zone. The brush is only a device for knocking the sheet down and does not take part in braking here. Various disadvantages occur when vacuum alone is used to slow down the sheets. Vacuum does not work satisfactorily when using several paper paths nor when using high speeds due to the great inertia of the sheets. With multiple paper paths, the vacuum acts more effectively on the bottom sheets than on the top sheets, and the inertia of the top sheets will send these through with greater speed. In this way, a phenomenon called "shuffling" occurs which results in the top sheet being moved further than the bottom sheet. This becomes critical at high speeds.
Et formål med oppfinnelsen er å forbedre innretningen og framgangsmåten for nedbremsing slik at kuttete ark som blir transportert med høy hastighet, blir bremset effektivt, og brakt til å overlappe ved framføring til oppsamlingssonen uten at det oppstår risiko for ødeleggelse av arkene. Dette blir oppnådd ved de trekk som framgår av den karakteriserende delen av patentkrav 1. One purpose of the invention is to improve the device and the procedure for deceleration so that cut sheets that are transported at high speed are effectively braked and brought to overlap during conveyance to the collection zone without there being a risk of destroying the sheets. This is achieved by the features that appear in the characterizing part of patent claim 1.
I denne oppfinnelsen er den vanlige overlappingen elimi-nert. Istedenfor å stoppe arket med framkanten er en endestopp-anordning som i en første utførelse omfatter en toppbørste-rulle som slår ned arkenden og tillater det neste arket å passere over og overlappe. Børsterullen tar arket noer enden og presser det ned mot en rulle som går med en hastighet på ca. 76.2-106.7 m/min. Ved at børsten forlater den langsomtgående rullen er det ikke noe som driver arket inn i samlekassen, så det ligger på rullen inntil børsten kommer rundt igjen og slår ned enden på det neste arket. Børsten presser dermed på begge arkene. Det nederste arket blir da akselerert til en hastighet av 45.7- 76.2 m/min. inn i papiransamlingen mens det øverste arket blir på den uklemte rullen, ventende på neste nedpres-s ing. In this invention, the usual overlap is eliminated. Instead of stopping the sheet with the leading edge is an end stop device which, in a first embodiment, comprises a top brush roll which strikes down the end of the sheet and allows the next sheet to pass over and overlap. The brush roller takes the sheet towards the end and presses it down against a roller which moves at a speed of approx. 76.2-106.7 m/min. As the brush leaves the slow-moving roller, there is nothing to propel the sheet into the collection box, so it sits on the roller until the brush comes around again and hits the end of the next sheet. The brush thus presses on both sheets. The bottom sheet is then accelerated to a speed of 45.7-76.2 m/min. into the paper stack while the top sheet remains on the unclamped roll, waiting for the next push-down.
En annen fordel med oppfinnelsen overfor kjent teknikk er at apparatet og framgangsmåten i samsvar med oppfinnelsen består i at det dannes et mykt "napp" mellom en roterende børste og den roterende bremserullen, som bremser arket uten å ødelegge det. Den roterende børsten brukes ved siden av å danne mykt "napp" også til samtidig å slå ned bakre ende av arkene, og på den måten tillate at arkene overlapper når de blir ført inn i oppsamlingssonen. En ytterligere fordel består i at arkene ikke blir ført fremover når de ikke blir "nappet" mot den roterende rullen av "nappe"-organet. Hvert ark vil da bare forbli på toppen av rullen. Det er bare når det neste påfølgende arket blir ført fram over det første arket og et nytt "napp" dannes av børsten at det nederste arket blir ført inn i oppsamlingssonen samtidig som det øverste arket inntar den plasseringen som det nederste arket hadde før "nappet". Ved denne framgangsmåten blir arkene bare flyttet til sine bestemte plasseringer bare ved aksjon av nappeorganet (børs- Another advantage of the invention over the prior art is that the apparatus and method according to the invention consists in the formation of a soft "pacifier" between a rotating brush and the rotating brake roller, which brakes the sheet without destroying it. The rotating brush is used in addition to forming soft "pacifiers" to simultaneously strike down the trailing end of the sheets, thereby allowing the sheets to overlap as they are fed into the collection zone. A further advantage consists in the fact that the sheets are not carried forward when they are not "nipped" against the rotating roller by the "nipping" means. Each sheet will then only remain on top of the roll. It is only when the next successive sheet is advanced over the first sheet and a new "nip" is formed by the brush that the bottom sheet is brought into the collection zone at the same time that the top sheet occupies the position that the bottom sheet had before the "nip". . In this procedure, the sheets are only moved to their specific positions only by action of the nipping device (stock-

En utførelsesform av oppfinnelsen vil nå bli beskrevet An embodiment of the invention will now be described
med eksempel og med referanse til tegningene hvor; by example and with reference to the drawings where;

utførelse av oppfinnelsen. execution of the invention.
Med referanse til fig 1 er det vist en serie med ark slik som papirarkene 10, 12, 14 og 16, som er tilkuttet av en kniv oppstrøms fig. 1 og deretter ført i en rekkevis strøm. Et høyhastighets transportbåndsystem 18 som har et båndorgan 20 opphengt på en rull 22 i den ene enden og i den andre enden en tilsvarende ikke vist rull, tjener til å transportere de tilkuttetde arkene i høy hastighet. Høyhastighetsbåndet 20 transporterer arkene ved hastigheter opp til 457.5 m/min. With reference to Fig. 1, there is shown a series of sheets such as paper sheets 10, 12, 14 and 16, which have been cut by a knife upstream of Fig. 1 and then passed in a series of currents. A high-speed conveyor belt system 18 which has a belt member 20 suspended on a roller 22 at one end and at the other end a corresponding roller, not shown, serves to transport the cut sheets at high speed. The high speed belt 20 transports the sheets at speeds up to 457.5 m/min.
Rett etter rullen 22 er det montert en bremseanordning i samsvar med oppfinnelsens prinsipper. I utførelsen vist i fig. 1 er det montert en endestoppeanordning som omfatter en topp-børsterulle 24 og en langsomt roterende rulle 26. Begge rullene 24 og 26 er drevet v.h.a. en elektrisk motor 28 og med hensiktsmessige giranordninger 30. Immediately after the roller 22, a braking device is fitted in accordance with the principles of the invention. In the embodiment shown in fig. 1, an end stop device is mounted which comprises a top brush roller 24 and a slowly rotating roller 26. Both rollers 24 and 26 are driven by an electric motor 28 and with suitable gear devices 30.
Den langsomt roterende rullen 26 roterer med overflate-hastighet av ca. 76.2-106.7 m/min. Børsterullen har to radielt utstående børster 32, 34 som er plassert diamentralt i forhold til hverandre på rullen 24. Etterhvert som arkene mates ut av transportsystemet 18 passerer fremkanten på arkene mellom de to rullene 24, 26 når børstene 32, 34 er i omtrent horisontal stilling slik at arkets framkant kan passere mellom de to rullene. Når arket drives videre fremover mellom de to rullene vil en av børstene ta arket nær enden og tvinge det nedover til den langsomt roterende rullen 26. Når børsten under videre omdreining ikke trykker mot rullen 26 er det ikke noe som driver arket inn i stabelen så det blir værende på rullen til børsta tar enden på neste ark og presser dette ned. Når det skjer vil børsten legge press på begge arkene. I fig 1 er det vist at børsten 32 slår ned enden på arket 10 mens arket 12 ennå henger på den langsomtgående rullen 26. Når børsten legger press på begge arkene vil det nederste arket 12 bli akselerert til en hastighet av ca. 45.7-76.2 m/min. inn i papiransamlingen som vist med arket 14. Det øverste arket forblir på den uklemte langsomtgående rullen 26 inntil neste nedpressing av børsten. På dennne måten oppnås at arkene føres inn i samlekassen med lav hastighet. The slowly rotating roller 26 rotates at a surface speed of approx. 76.2-106.7 m/min. The brush roll has two radially protruding brushes 32, 34 which are placed diametrically in relation to each other on the roll 24. As the sheets are fed out of the transport system 18, the leading edge of the sheets passes between the two rolls 24, 26 when the brushes 32, 34 are in an approximately horizontal position so that the leading edge of the sheet can pass between the two rollers. When the sheet is driven further forward between the two rollers, one of the brushes will catch the sheet near the end and force it down to the slowly rotating roller 26. When the brush does not press against the roller 26 during further rotation, there is nothing that drives the sheet into the stack so it remains on the roll until the brush catches the end of the next sheet and presses it down. When that happens, the brush will put pressure on both sheets. In Fig. 1, it is shown that the brush 32 strikes down the end of the sheet 10 while the sheet 12 is still hanging on the slow-moving roller 26. When the brush applies pressure to both sheets, the bottom sheet 12 will be accelerated to a speed of approx. 45.7-76.2 m/min. into the paper stack as shown by sheet 14. The top sheet remains on the unclamped slow-moving roller 26 until the next brush depression. In this way, it is achieved that the sheets are fed into the collection box at low speed.
Flere bunker (av gitt størrelse) samles i samlekassa hvor lufta presses ut av bunkene. Bunkene fjernes fra bunnen av papiransamlingen. Dette er vist i fig. 1 hvor bunken 38 fjernes. Et bunkesplitteorgan 40 med en skarp egg 42 framme, til å trenge inn i papiranstabelen 36 og med et belte 44 på den spydformede delen av splitteorganet føres inn i stabelen 36. Den utstikkende fronteggen skiller et øvre ark 46 på bunken 38 fra et nedre ark 48 i papirstabelen 36. Beltet 44 på det spydformede splitteorganet 40 er opphengt på frontrullen 50 og bakrullen 52. Når splitteorganet innføres i papiranstabelen 36, og skiller bunken 38 fra resten av papiranstabelen, løper beltet 44 med urviseren på rullene 50 og 52 som vist i fig. 1, slik at den delen av beltet som er i kontakt med det nederste arket i papiransamlingen er stasjonær i forhold til dette Several piles (of a given size) are collected in the collection box where the air is forced out of the piles. The stacks are removed from the bottom of the paper stack. This is shown in fig. 1 where the pile 38 is removed. A stack splitting device 40 with a sharp edge 42 at the front, for penetrating the paper stack 36 and with a belt 44 on the spear-shaped part of the splitting device is introduced into the stack 36. The protruding front edge separates an upper sheet 46 of the stack 38 from a lower sheet 48 in the paper stack 36. The belt 44 on the spear-shaped splitting member 40 is suspended on the front roller 50 and the rear roller 52. When the splitting member is introduced into the paper stack 36, and separates the pile 38 from the rest of the paper stack, the belt 44 runs clockwise on the rollers 50 and 52 as shown in fig. . 1, so that the part of the belt that is in contact with the bottom sheet of the paper stack is stationary in relation to this
arket inntil splitteorganet er ført helt inn. the sheet until the splitting device is fully inserted.
Under det spydformede splitteorganet 40 er plassert ei skyveplate 54 som ligger mot sideflaten 56 til bunken 38 og tjener til å flytte den sideveis etter hvert som det spydformede splitteorganet 40 trenger inn i papiranstabelen 36. Høyden på skyveplaten 54 er litt høyere enn tykkelsen på den utskilte bunken 38 for å oppnå en klaring, vist ved 58, mellom det øverste arket 46 i den borttagne bunken 38 og beltet 44, på rullene 50 og 52. Below the spear-shaped splitting member 40 is placed a sliding plate 54 which lies against the side surface 56 of the stack 38 and serves to move it laterally as the spear-shaped splitting member 40 penetrates into the paper stack 36. The height of the sliding plate 54 is slightly higher than the thickness of the separated the stack 38 to obtain a clearance, shown at 58, between the top sheet 46 of the removed stack 38 and the belt 44, on the rolls 50 and 52.
Papiranstabelen 36 er normalt holdt oppe av et løftebord som omfattter to frittrullende transportbånd 60, 62 som ligger an mot det nedre arket 64 i den nederste bunken i papiranstabelen 36. De to transportbåndene, 60 og 62, er montert på et delt løftebord som bærer bunkene mens splitteorganet føres inn og trekkes tilbake. De to transportbåndene er montert med vertikal uavhengig bevegelighet slik at bunken og papiranstabelen 36 er kontinuerlig understøttet. The paper stack 36 is normally held up by a lift table comprising two free-rolling conveyor belts 60, 62 which abut against the lower sheet 64 in the bottom stack of the paper stack 36. The two conveyor belts, 60 and 62, are mounted on a split lift table which carries the stacks while the splitting organ is introduced and withdrawn. The two conveyor belts are mounted with vertical independent movement so that the stack and the paper stack 36 are continuously supported.
Når det spydformede splitteorganet innføres i papiranstabelen 36 vil skyveplaten 54 flytte bunken 38, båret på de frittrullende transportbåndene 60, 62 mot et luftbord 66. Når bunken 38 er deponert på luftbordet 66 som vist med stiplede linjer, vil mesteparten av vekten bæres av en luftpute dannet av trykkluft fra ledningene 68 i luftbordet som slippes ut mot overflaten 70 til bordet gjennom adskilte åpninger 72. Langs-gående transportbånd 74, 76 som er høyere nivellert enn overflaten 70 til luftbordet 66, benyttes til å transportere bunkene videre til neste stasjon i papirbehandlingssystemet. When the spear-shaped splitting member is introduced into the paper stack 36, the sliding plate 54 will move the stack 38, carried on the free-rolling conveyor belts 60, 62, towards an air table 66. When the stack 38 is deposited on the air table 66 as shown by dashed lines, most of the weight will be carried by an air cushion formed by compressed air from the lines 68 in the air table which is discharged towards the surface 70 of the table through separate openings 72. Longitudinal conveyor belts 74, 76 which are higher level than the surface 70 of the air table 66 are used to transport the stacks on to the next station in the paper processing system .
Når det spydformede splitteorganet trekkes tilbake fra papiranstabelen 36 beveges det frittrullende transportbåndet 60 vertikalt til det støtter opp under papiranstabelen mens splitteorganet fortsetter tilbaketrekningen, og deretter beveges transportbåndet 62 også vertikalt og støtter opp under papiranstabelen. When the spear-shaped splitting member is withdrawn from the paper stack 36, the free-rolling conveyor belt 60 is moved vertically until it supports under the paper stack while the splitting member continues its withdrawal, and then the conveyor belt 62 is also moved vertically and supports up under the paper stack.
Det er ønskelig at det øverste arket, vist med ark 16 i fig. 1, i papiranstabelen forblir i samme nivå i forhold til rullene 26, 24 gjennom hele driften. Derfor er splitteorganet 40 og transportbåndene 60, 62 montert på vertikalt bevegelige skaft 78. For at splitteorganet skal kunne trenge inn i papiranstabelen 36, mens papiranstabelen er i samlekassen, har samlekassen 80, som vist i fig. 1, en utsparing 82 som sammen-faller med entringspunktet til splitteorganet 40. Når splitteorganet føres inn i papiranstabelen 36 vil det også beveges nedover slik at når det når veggen 84 på motsatt side av samlekassen 80 vil det passere under en kant 86 til denne veggen. It is desirable that the top sheet, shown with sheet 16 in fig. 1, in the paper stack remains at the same level in relation to the rolls 26, 24 throughout the operation. Therefore, the splitting device 40 and the conveyor belts 60, 62 are mounted on vertically movable shafts 78. In order for the splitting device to be able to penetrate the paper stack 36, while the paper stack is in the collection box, the collection box 80, as shown in fig. 1, a recess 82 which coincides with the entry point of the splitting member 40. When the splitting member is introduced into the paper stack 36 it will also be moved downwards so that when it reaches the wall 84 on the opposite side of the collection box 80 it will pass under an edge 86 of this wall .
I fig. 2 er vist en alternativ utførelse av bunkeutskil-lingsanordningen, hvor papiranstabelen 36a, splitteorganet 40a, de frittrullende transportbåndene 60a og 62a og luftbordet er skråstilt i samme vinkel, for å samordne papiranstab-lings og bunkeutskillingsprosedyren. Luftbordet 66a har et sidemontert transportbånd 88 som er drevet med en motor 90 og som transporterer de utskilte bunkene 38a til neste ledd i prosessen, istedenfor transportbåndene 74 og 76 i utførelsen i fig. 1. I alle andre henseende er denne utførelsen lik med den i fig. 1, men denne utførelsen utnytter i en viss grad tyngde-kraften til hjelp ved papiranstabelen 36a og fjerning av In fig. 2 shows an alternative embodiment of the pile separation device, where the paper stacker 36a, the splitting member 40a, the free-rolling conveyor belts 60a and 62a and the air table are inclined at the same angle, in order to coordinate the paper stacking and pile separation procedure. The air table 66a has a side-mounted conveyor belt 88 which is driven by a motor 90 and which transports the separated piles 38a to the next stage in the process, instead of the conveyor belts 74 and 76 in the embodiment in fig. 1. In all other respects this embodiment is similar to that of fig. 1, but this design makes use of gravity to a certain extent to aid in the stacking of paper 36a and removal of
utskilte bunker 38a. separated bunker 38a.
Fig. 2 viser børsterullen 24 i en annen omdreiningsposi-sjon enn vist i fig.l og det er vist at et papirark 92 er fremført mellom rullene 24, 26 v.h.a. det hurtigående transportbåndet 18. Det kan også sées at børsten 34 vil ta enden på arket 92 og presse den ned på rullen 26 hvor trykket fra børsten 34 vil gjøre at arket 10 som ligger på rullen 26, akselererer og beveges inn i papiranstabelen 36a. Fig. 2 shows the brush roll 24 in a different rotational position than shown in Fig. 1 and it is shown that a sheet of paper 92 is advanced between the rolls 24, 26 v.h.a. the high-speed conveyor belt 18. It can also be seen that the brush 34 will take the end of the sheet 92 and press it down onto the roller 26, where the pressure from the brush 34 will cause the sheet 10 lying on the roller 26 to accelerate and move into the paper stack 36a.
