Fremgangsmåde ved fremstilling af dobbeltlakerede emballageemner ud fra trykte kartonark, samt produktionsanlæg og stansemaskine til brug herved.Method of producing double-lacquered packaging items from printed cardboard sheets, as well as production plant and punching machine for use therewith.
Den foreliggende opfindelse angår et produktionssy-.5 stem for kartonemballageemner, bestående af arktrykkemaskiner, en udrustning til overfladelakering af de trykte ark, og et antal stansemaskiner til udstansning af kartonemnerne fra arkene. Det er sædvanligt, at flerfarve-trykkemaskinerne er udformet med et lakeringsværk, som 10 påfører en klar lak ovenpå den trykte arkside, hvorved der kan opnås en eftertragtet overfladeglans på emnerne, men den nævnte ekstra eller separate lakeringsudrustning er ønskelig derved, at det for en vis del af produktionen kan være påkrævet at efterbehandle arkene for opnå-15 else af en ekstra god overfladeglans. Dette er en fordyrende behandling, men resultatet bliver mærkbart bedre, fordi arkene allerede er 'grundet' med det første laklag.The present invention relates to a production system for cardboard packaging items consisting of sheet printing machines, a surface coating equipment for the printed sheets, and a number of punching machines for stamping the cardboard items from the sheets. It is customary for the multicolor printing machines to be designed with a paint job which applies a clear varnish on top of the printed sheet side, thereby obtaining a coveted surface gloss on the workpieces, but the said additional or separate coating equipment is desirable in that a Some of the production may be required to post-process the sheets to obtain an extra good surface gloss. This is an expensive treatment, but the result is noticeably better because the sheets are already 'primed' with the first coat of paint.
Det har været forsøgt at anbringe efterlakerings-20 værket i direkte tilslutning til en trykkemaskine, men resultatet bliver ikke specielt godt, fordi lakeringsunderlaget trods brug af mellemvarme ikke kan nå at være helt tørt eller hærdet inden påføringen af det ekstra laklag, og det er derfor det mest almindelige, at der 25 gøres brug af den nævnte separate lakeringsudrustning, som givetvis vil være dyrere, men altså også giver produkterne en bedre kvalitet, idet de ark, der skal efterbehandles, kan nå at tørre ordentligt, f.eks. ved at ligge til næste dag. I almindelighed vil det kun være en 30 mindre del af produktionen, der skal efterlakeres, og ved brugen af den separate lakeringsmaskine er det en tilhørende fordel, at denne maskine kan modtage ark fra enhver af de benyttede trykkemaskiner; disse vil ofte være udrustet med forskellige antal af farvetrykværker, DK 167664 B1 2 og et benyttet efterlakeringsværk bør naturligvis være anbragt på en maskine med det højeste antal farvetrykværker, hvilket så kan give en kapacitetsbegrænsning, når det er tryk med færre farver, der skal efter lakeres.Attempts have been made to place the finishing paint directly in connection with a printing machine, but the result is not very good, because the coating substrate, despite the use of intermediate heat, can not reach completely dry or hardened before the application of the extra paint layer, which is why the most common is the use of said separate coating equipment, which of course will be more expensive, but thus also gives the products a better quality, since the sheets to be processed can now dry properly, e.g. by lying to the next day. Generally, only a minor portion of production will need to be repainted, and with the use of the separate coating machine it is an associated advantage that this machine can receive sheets from any of the printing machines used; these will often be equipped with different numbers of color prints, DK 167664 B1 2 and a used paint finisher should of course be placed on a machine with the highest number of color prints, which can then give a capacity limitation when there are fewer colors to print. painted.
Ved brug af den separate lakeringsmaskine kan alle tryk-5 kemaskinerne udnyttes optimalt.By using the separate coating machine, all the printing machines can be optimally utilized.
Til gengæld optræder der så en klar operativ opdeling mellem tre forskellige typer af enheder i systemet, nemlig henholdsvis trykkemaskinerne, efterlakeringsenheden og stansemaskinerne, og til hver af disse enheder 10 hører det nødvendige indfødningsapparatur for arkene, en såkaldt ilægger,ligesom der skal udføres interne transporter af arkstabler mellem enhederne. En fordel ved brugen af et efterlakeringsværk på en eller for så vidt flere af trykkemaskinerne er netop, at dette værk 15 så kan arbejde 'on line', dvs. uden anvendelse af en særlig ilægger for stabelvis tilbragte ark.On the other hand, there is a clear operational division between three different types of units in the system, namely the printing machines, the finishing unit and the punching machines, and each of these units 10 has the necessary feeding apparatus for the sheets, a so-called inserter, as well as for internal transport. of sheet stacks between the devices. An advantage of using a finishing work on one or in so far as several of the printing machines is precisely that this work 15 can then work 'on line', ie. without the use of a special feeder for stacked sheets.
Der tilstræbes ved nærværende opfindelse netop en sådan forenkling af det samlede system, dog uden at der optræder de nævnte ulemper med hensyn til nedsat kvali-20 tet af efterlakeringen.The present invention seeks to achieve such a simplification of the overall system, but without the mentioned disadvantages with regard to the reduced quality of the paint finish.
Ifølge opfindelsen arrangeres den separate efterlakeringsenhed i direkte operativ sammenkobling med en af de i systemet forekommende stansemaskiner, nemlig anbragt foran denne, således at arkene fra tilbragte ark-25 stabler indfødes successivt i efter lakeringsenheden og derfra løbende føres til stansemaskinen, uden at denne i sig selv skal være udført med en tilføringsenhed for enkeltark fra tilførte arkstabler.According to the invention, the separate finishing unit is arranged in direct operative coupling with one of the punching machines present in the system, namely located in front of it, so that the sheets from spent sheet stacks are successively fed in after the coating unit and then continuously fed to the punching machine without it per se. itself must be provided with a single-sheet feeder unit from loaded sheet stacks.
Stansemaskinerne arbejder uafhængigt af, om der er 30 tale om tryk med flere eller færre farver, således at efterlakeringsenheden ret ukritisk kan anbringes i forbindelse med en hvilken som helst af stansemaskinerne.The punching machines operate independently of whether there are more or less color prints, so that the finisher unit can be placed uncritically in connection with any of the punching machines.
Da påtrykket og forlakeringen på arkene kan være godt tørrede, når arkstablerne tilbringes til ilæggeren 35 på den kombinerede efter lakerings- og stansemaskine DK 167664 B1 3 opnås god sikkerhed for, at efter laker ingen kan udføres med topkvalitet, og tilbage vil kun være det problem, at der også i stansemaskinen stilles visse krav til, at overfladelaget på arkene skal være rimeligt tørt eller 5 hærdet, da laget ellers kan beskadiges lokalt af de trykorganer, som i stansemaskinen fastholder arkene under stansningen. Dette krav til tørringen eller hærdningen er imidlertid mindre rigoristisk end det modsvarende krav om tørhed inden tilføjelsen af det ekstra 10 laklag, og kravet kan langt lettere tilgodeses ved brug af en passende mellemvarmning eller anden hærdningsbehandling mellem påføreisen af det yderligere laklag og den efterfølgende udstansning af kartonemnerne. Den ønskværdige direkte overførsel af arkene fra efterlake-15 ringsenheden til stansemaskinen kan således foregå gennem en forholdsvis kort tørrings- eller hærdningssektion, hvorved det bliver fuldt realistisk at sammenkoble efter lakeringsenheden med stansemaskinen, dvs. fortrinsvis med den ene af flere stansemaskiner i systemet, alt 20 efter behovet for efterbehandling af de producerede ark.Since the printing and leaching of the sheets can be well dried when the sheet stacks are applied to the feeder 35 on the combined after lacquer and punch machine DK 167664 B1 3, good assurance is obtained that after lacquers no one can be performed with top quality and back will only be the problem Also, in the punching machine there are certain requirements that the surface layer of the sheets must be reasonably dry or hardened, otherwise the layer can be damaged locally by the pressure means which in the punching machine hold the sheets during the punching. However, this requirement for drying or curing is less rigorous than the corresponding dryness requirement prior to the addition of the extra 10 lacquer layers, and the requirement can be far more easily met by the use of an appropriate intermediate heating or other curing treatment between the application of the additional lacquer layer and the subsequent punching of the lacquer. blanks. Thus, the desirable direct transfer of the sheets from the finisher unit to the punching machine can take place through a relatively short drying or curing section, whereby it becomes fully realistic to couple the coating unit with the punching machine, i.e. preferably with one of several punching machines in the system, totaling 20 as needed for finishing the sheets produced.
Ved opfindelsen kan trykkemaskinerne udnyttes optimalt samtidigt med, at der ikke kræves nogen separat aflevering af arkstabler med efterbehandlede, højkvalificerede ark til stansemaskinerne.In the invention, the printing machines can be utilized optimally at the same time as no separate delivery of sheet stacks with post-processed, high-quality sheets for the punching machines is required.
25 Opfindelsen er illustreret skematisk på tegningen, hvor fig. 1 er et diagram af et traditionelt trykkerianlæg, fig. 2 et tilsvarende diagram af et anlæg eller et 30 system ifølge opfindelsen, og fig. 3 et sidebillede af en kombineret efterlakerings- og stanseenhed ifølge opfindelsen.The invention is illustrated schematically in the drawing, in which fig. 1 is a diagram of a traditional printing plant; FIG. 2 is a corresponding diagram of a plant or system according to the invention; and FIG. 3 is a side view of a combined finishing and punching unit according to the invention.
I fig. 1 er det vist, at et antal trykkemaskiner 2 i en virksomhed hver er forsynet med et lakereværk 4, og 35 at der desuden forefindes et antal stansemaskiner 6 med hver sin ilægger 8, hvortil der kan tilføres stabler DK 167664 B1 4 af trykte ark fra enhver af trykkemaskinerne 2.In FIG. 1, it is shown that a number of printing machines 2 in one company are each provided with a paintwork 4, and 35 that there are furthermore a number of punching machines 6 with each of its inserts 8, to which stacks DK 167664 B1 4 of printed sheets from any of the printing machines 2.
Det er antydet, at en enkelt trykkemaskine kan være forsynet med et ekstra lakereværk 10, men som omtalt kan dette af flere grunde være mindre hensigtsmæssigt, og 5 det foretrækkes normalt at gøre brug af en separat lake-ringsenhed 12 med ilægger 14, som så kan modtage stabler af ark til efterbehandling fra enhver af trykkemaskinerne, ligesom trykket og det første laklag på arkene kan nå at være ordentligt tørret eller hærdet inden det 10 ekstra laklag påføres.It has been suggested that a single printing machine may be provided with an additional paintwork 10, but as mentioned this may be less convenient for a number of reasons and 5 it is usually preferable to use a separate storage unit 12 with inserter 14 which then can receive stacks of sheets for finishing from any of the printing machines, just as the printing and first lacquer layer on the sheets may now be properly dried or cured before the additional 10 lacquer layers are applied.
Stansemaskinerne 6 kan modtage arkstabler både fra enhver af trykkemaskinerne 2 og fra lakeringsenheden 12, hvilket er antydet med forskellige forbindelseslinier.The punching machines 6 can receive sheet stacks both from any of the printing machines 2 and from the coating unit 12, which is indicated by different connection lines.
Det vil så tilsvarende gælde, at arkene i de forskellige 15 stabler kan være godt tørrede inden stansningen udføres, således at arkene kan håndteres uden beskadigelse af den trykte og lakerede overflade.Similarly, the sheets in the various stacks may be well dried before the punching is performed so that the sheets can be handled without damage to the printed and varnished surface.
Det er imidlertid ved opfindelsen indset, at netop tørringen eller hærdningen af det omtalte ekstra laklag 20 kan foregå så hurtigt, at det er muligt at sammenkoble den ekstra lakeringsenhed 12 med en af stansemaskinerne 6, når der imellem disse enheder tilvejebringes en passende tørrings- eller hærdningszone 16, der successivt gennemløbes af de efter lakerede ark, se fig. 2. Arkene i 25 de stabler, der kommer fra trykkemaskinerne 2, kan fortsat være godt tørrede, når de bringes til lakeringsenheden 12 f.eks. dagen efter trykningen, idet de så kan være tørret ' i dybden', altså ikke blot i den trykte overflade, men også i materialet neden under denne, 30 således at der for efter laker ingen er skabt optimale betingelser for et godt resultat. Ved tørringen eller hærdningen af det ekstra laklag er det kun selve dette lag, det drejer sig om, dvs. et ganske tyndt overfladelag, der ikke er delvis nedtrængende i et underliggende 35 porøst lag, og netop derfor kan der ved hjælp af en rimeligt kort tørre- eller hærdezone 12 opnås en fuldt DK 167664 B1 5 tilstrækkelig fiksering til at arkene derefter kan håndteres i stansemaskinen uden at arkoverfladen tager skade.However, it is recognized by the invention that precisely the drying or curing of the aforementioned auxiliary lacquer layer 20 can take place so quickly that it is possible to interconnect the auxiliary lacquer unit 12 with one of the punching machines 6 when a suitable drying or drying device is provided between these units. curing zone 16 which is successively traversed by the lacquered sheets, see FIG. 2. The sheets in the stacks coming from the printing machines 2 may continue to be well dried when brought to the coating unit 12 e.g. the day after printing, since they can then be dried 'in depth', ie not only in the printed surface, but also in the material underneath it, so that for varnishes no optimum conditions have been created for a good result. In the drying or curing of the extra lacquer layer it is only this layer itself, ie. a quite thin surface layer that is not partially penetrating into an underlying porous layer, and precisely because of this a relatively short drying or curing zone 12 a full fixation can be obtained so that the sheets can then be handled in the punching machine without damaging the sheet surface.
Længden eller effekten af tørrezonen 16 bør afstem-5 mes på en sådan måde, at stansemaskinen 6 kan arbejde med fuld operativ hastighed med ark, hvis ekstra laklag er nået at tørre eller hærdes tilstrækkeligt efter behandlingen i lakeringsenheden 12.The length or effect of the drying zone 16 should be adjusted in such a way that the punching machine 6 can operate at full operating speed with sheets if additional varnish layers have been sufficiently dry or cured after treatment in the lacquer unit 12.
I fig. 3 er antydet en praktisk udførelse af den 10 kombinerede lakerings- og stansemaskine 12,6. Den tilhørende indføderenhed 14 er vist i figurens højre side, og det vil forstås, at man ved systemet ifølge opfindelsen kan undgå at benytte en separat ilægger til stansemaskinen 6, ligesom man undgår at skulle transportere 15 arkstabler til stansemaskinen fra den i fig. 1 viste, separate lakeringsenhed 12.In FIG. 3 is a practical embodiment of the 10 combined paint and punching machine 12.6. The associated feeder unit 14 is shown in the right-hand side of the figure, and it will be appreciated that the system according to the invention can avoid using a separate feeder for the punching machine 6, as well as avoiding having to transport 15 sheet stacks to the punching machine from the one shown in FIG. 1, separate coating unit 12.
Der er intet i vejen for, at samme stansemaskine 6 kan benyttes til håndtering af ark, der ikke ønskes ekstra lakeret, idet man så blot kan undlade at aktivere 20 henholdsvis lakeringsenheden 12 og tørretunnelen 16, dvs. lade arkene passere fra indføderen 14 direkte frem til stansemaskinen uden mellemliggende behandling. Stansemaskinen er altså ikke dedikeret til blot at håndtere dobbeltlakerede ark, dvs. den er anvendelig også i peri-25 oder, hvor det ikke er aktuelt at producere ark af denne type.There is nothing in the way that the same punching machine 6 can be used for handling sheets that are not wanted extra lacquered, since one can simply fail to activate the lacquer unit 12 and the drying tunnel 16, ie. allowing the sheets to pass from the feeder 14 directly to the punching machine without intermediate processing. Thus, the punching machine is not dedicated to simply handling double-lacquered sheets, ie. it is also applicable in peri-25 odes where it is not appropriate to produce sheets of this type.
Hvis der i en given virksomhed er en særligt stor delproduktion af arkemner, som skal dobbeltlakeres, kan det naturligvis være hensigtsmæssigt, at den i fig. 3 30 viste kombination benyttes for mere end blot en enkelt stansemaskines vedkommende.If, in a given business, there is a particularly large sub-production of sheets to be double-coated, it may, of course, be appropriate that the embodiment shown in FIG. 330 is used for more than just a single punching machine.
