DK 172029 B1 INDRETNING TIL PÅFØRING AF LIM PÅ OBJEKTER Opfindelsens anvendelsesområde 5 Denne opfindelse angår en indretning til påføring af lim på objekter, især etiketter, som i en etiketteringsmaskine skal overføres til og fastklæbes på emner, der skal mærkes.GB 172029 B1 DEVICE FOR APPLICATION OF ADMINISTS ON OBJECTS The scope of the invention 5 This invention relates to a device for applying adhesives to objects, especially labels, which in a labeling machine must be transferred to and adhered to items to be labeled.
Kendt teknik 10 I kendte etiketteringsmaskiner anvendes forud trykte etiketter, der leveres i ruller med silikonebelagt bagpapir til beskyttelse af selvklæbende lim på etiketternes bagside. Bagpapiret er affald, som skal bortskaffes, hvilket 15 miljømæssigt er vanskeligt som følge af silikonebelægningen, der også fylder op på arbejdspladsen. Ved skift til en ny etiketstørrelse eller et nyt påtryk må de første 5-10 etiketter kasseres, før den første nye etiket kan anbringes på emnet. Man er derfor gået over til at anvende etikette-20 ringsmaskiner, hvor etiketternes trykkes i etiketteringsmaskinen og i en indretning forsynes med lim på bagsiden umiddelbart før etiketterne placeres på emnerne.Prior Art 10 In prior art labeling machines, preprinted labels are supplied, supplied in rolls with silicone-coated backing paper to protect adhesive adhesive on the back of the labels. The backing paper is waste that must be disposed of, which is environmentally difficult due to the silicone coating that also fills up in the workplace. When changing to a new label size or print, the first 5-10 labels must be discarded before the first new label can be placed on the item. Therefore, labeling machines have been used where the labels are printed in the labeling machine and in a device provided with glue on the back immediately before the labels are placed on the blanks.
Det tekniske problem, der skal løses 25The technical problem to be solved 25
Fra EP offentliggørelsesskrift nr. 0 268 425 kendes en indretning til påføring af lim på objekter, hvilken indretning omfatter en valse, hvis rundtgående overflade skiftevis har forhøjninger og fordybninger, som er beklædt med et sugende 30 materiale, såsom filt. Valsen er hul og er indvendigt beklædt med svampegummi og har inderst et centralt rør forsynet med åbninger, så lim, der tilføres gennem det centrale rør, under den ved rotationen af valsen frembragte centrifugalkraft kan sive ud i svampegummiet og derfra gennem 35 huller i bunden af fordybninger videre ud i filtbeklædningen. På grund af forhøjningerne anbringes limen i striber DK 172029 B1 2 på etiketterne, hvorefter striberne kun delvist udbredes til større områder på etiketternes bagside ved overføringen til emnerne, der skal mærkes med etiketterne. Limen påføres således kun ujævnt ved den kendte valse.EP-A-0 268 425 discloses a device for applying glue to objects, which comprises a roller, the circumferential surface of which alternately has ridges and depressions coated with a absorbent material, such as felt. The roller is hollow and is internally lined with sponge rubber and has at least one central tube provided with openings, so that glue supplied through the central tube under the centrifugal force produced by the rotation of the roll can seep into the sponge rubber and thence through 35 holes at the bottom of the recesses further into the felt lining. Because of the elevations, the adhesive is placed in stripes DK 172029 B1 2 on the labels, after which the stripes are only partially spread to larger areas on the back of the labels when transferring to the items to be labeled. Thus, the glue is applied only unevenly to the known roller.

Fra US patentskrift nr. 3.763.823 kendes også en indretning til påføring af lim på objekter, hvilken valse har en glat overflade og har et centralt rør til tilførsel af lim til valsen. Limen passerer under den ved valsens rotation frem-10 bragte centrifugalkraft ud gennem huller i valsens overfla de, så der med indbyrdes afstande i rotationsretningen fremkommer dråber af lim på overfladen. Dråberne presses derefter ud over et større område af valsen, når objektet presses mod valsen, så limen fordeles i klatter på objek-15 tet.US Patent No. 3,763,823 also discloses a device for applying glue to objects which roll has a smooth surface and has a central tube for applying glue to the roll. The glue passes during the centrifugal force produced by the rotation of the roll through holes in the surface of the roll, so that droplets of glue appear on the surface with mutual distances in the direction of rotation. The drops are then pressed out over a larger area of the roller as the object is pressed against the roller so that the glue is distributed in clumps on the object.
De kendte indretninger er uhensigtsmæssige i brug som følge af den uregelmæssige fordeling af limen. Det er derfor formålet med den foreliggende opfindelse at angive en indret-20 ning til påføring af lim på objekter, hvor indretningen fordeler limen i et ensartet lag over hele fladen af objekterne .The known devices are inappropriate in use due to the irregular distribution of the glue. It is therefore the object of the present invention to provide a device for applying glue to objects, the device distributing the glue in a uniform layer over the entire surface of the objects.
Den nye teknik 25The new technique 25
Dette formål opnås ved en indretning af den indledningsvis angivne art, hvilken indretning ifølge opfindelsen er særegen ved, at indretningen omfatter en tilførselsvalse med et perforeret, centralt rør, som er sluttet til en limtil-30 førsel, og et perifert, rundtgående skumgummilag, hvilket skumgummilag er i anlæg mod en aftagevalse, der i hovedsagen er anbragt oven over tilførselsvalsen og på sin side ligger an mod en påsmørevalse og kan overføre lim fra nævnte lag til denne.This object is achieved by a device of the type mentioned in the introduction, which device according to the invention is peculiar in that the device comprises a feed roller with a perforated central tube connected to a glue supply and a peripheral, circumferential foam rubber layer, which foam rubber layers are in contact with a take-off roller, which is generally positioned above the feed roller and in turn abuts on an application roller and can transfer glue from said layer to the same.
Den tekniske virkning 35 DK 172029 B1 3Technical effect 35 DK 172029 B1 3
Den tilførte lim trænger gennem det perforerede, centrale rør ud til skumgummilaget og fugter dette. Det gennemfugte-de skumgummilag overfører derefter limen i et jævnt lag til 5 aftagevalsen ved dennes anlæg mod skumgummilaget og videregiver limen til påsmørevalsen, som er indrettet til at komme i berøring med objekterne, der skal forsynes med lim på en flade.The applied adhesive penetrates through the perforated central tube to the foam rubber layer and wets this. The moistened foam rubber layer then transfers the glue in an even layer to the removal roller at its abutment against the foam rubber layer and passes the glue to the lubricating roller which is arranged to come into contact with the objects to be provided with glue on a surface.
10 Ved at anvende den ovennævnte nye teknik i forbindelse med den kendte teknik forsynes påsmørevalsen med et ensartet og jævnt fordelt lag af lim på hele sin overflade, hvilket limlag med samme jævne fordeling kan overføres til objekterne i en etiketteringsmaskine.Using the aforementioned new technique in connection with the prior art, the lubricating roller is provided with a uniform and evenly distributed layer of glue on its entire surface, which glue layer with the same even distribution can be transferred to the objects in a labeling machine.
15 Når påsmørevalsen er anbragt i det væsentlige oven over tilførselsvalsen, vil lim fra påsmørevalsen, som trykkes væk fra objekterne, dryppe ned på tilførselsvalsen og forblive i indretningen til fornyet anvendelse.When the lubricating roller is positioned substantially above the supply roll, glue from the lubricating roller which is pushed away from the objects will drip onto the supply roll and remain in the device for reuse.
2020
Det er fordelagtigt, at der ved siden af påsmørevalsen og i justerbart anlæg mod denne findes en afskraber, hvorfra afskrabet lim ligeledes kan dryppe ned på tilførselsvalsen.It is advantageous that there is a scraper next to the applicator roller and in an adjustable abutment against which the scraped glue can also drip down onto the feed roller.
25 Opfindelsen og specielt fordelagtige udførelsesformer forklares nærmere i det følgende under henvisning til figurerne på tegningen.The invention and particularly advantageous embodiments are explained in more detail below with reference to the figures in the drawing.
Figurfortegnelse 30Figure 30
Fig. 1 viser et sidebillede af en etiketteringsmaskine med en indretning ifølge opfindelsen til påføring af lim på objekter i form af etiketter, 35 fig. 2 viser et tværsnit i indretningen ifølge opfindel sen til påføring af lim på objekter i form af eti- DK 172029 B1 4 ketter, og fig. 3 viser det med III-III i fig. 2 antydede snit i indretningen ifølge opfindelsen til påføring af 5 lim på objekter i form af etiketter.FIG. 1 is a side view of a labeling machine with a device according to the invention for applying adhesive to objects in the form of labels; FIG. 2 is a cross-sectional view of the device according to the invention for applying adhesive to objects in the form of etiquette; and FIG. 3 shows that with III-III in FIG. 2 indicates sections in the device according to the invention for applying 5 adhesives to objects in the form of labels.
Indledningsvis forklares udformningen af en etiketterings-maskine med en indretning ifølge opfindelsen til påføring af lim på objekter i form af etiketter. Med 1 er angivet et 10 lager af en ubeskrevet papirbane, der er lagt i Z-folder, hvilken papirbane efter påtrykning af tekst og adskillelse i enkelte etiketter skal anbringes på emner 10, 12, der skal mærkes med etiketterne.Initially, the design of a labeling machine with a device according to the invention for the application of glue to objects in the form of labels is explained. 1 indicates a 10 stock of an unspecified paper web loaded in Z folds, which paper sheet after printing text and separating in individual labels should be placed on blanks 10, 12 to be labeled.
15 Et trykværk er angivet med 2 og kan trykke en given tekst på papirbanen, når den på kendt måde aftrækkes fra lageret 1 ved hjælp af en perforering langs kanterne. Indretningen ifølge opfindelsen til påføring af lim på objekter i form af etiketter er betegnet med 3 og befinder sig under et su-20 gehoved 4, som dels kan holde en etiket fast under trykningen og dels indeholder en stanse, der kan udskære den trykte etiket af papirbanen. Den overskydende papirbane er angivet med 9 og opsamles i en rulle under trykværket 2.A printing press is indicated by 2 and can print a given text on the paper web when it is pulled from the stock 1 in a known manner by means of a perforation along the edges. The device according to the invention for applying glue to objects in the form of labels is denoted by 3 and is located under a suction head 4 which can partly hold a label during printing and partly contains a punch which can cut the printed label from the paper sheet. The excess paper web is indicated by 9 and is collected in a roll under the printing plant 2.
Denne rulle af overskydende papirbane frembyder ingen van-25 skeligheder ved bortskaffelsen, da papiret ikke har belægninger af silikone. Pilene 6, 7 antyder bevægelser af sugehovedet 4 og pilene 5, 8 antyder en trykt etikets bevægelse i etiketteringsmaskinen. Endelig er med 11 angivet et transportbånd, hvorpå emner 10, 12, der skal afmærkes med 30 trykte etiketter, transporteres gennem etiketteringsmaskinen.This roll of excess paper web presents no problems with the disposal as the paper does not have silicone coatings. Arrows 6, 7 indicate movements of the suction head 4 and arrows 5, 8 indicate the movement of a printed label in the labeling machine. Finally, 11 is indicated a conveyor belt on which items 10, 12, to be marked with 30 printed labels, are conveyed through the labeling machine.
Der henvises nu til fig. 2 og 3, der viser et tværsnit henholdsvis et længdesnit i indretningen ifølge opfindelsen 35 til påføring af lim på objekter i form af etiketter.Referring now to FIG. 2 and 3 showing a cross section and a longitudinal section, respectively, of the device according to the invention 35 for applying glue to objects in the form of labels.
DK 172029 B1 5DK 172029 B1 5
Indretningen omfatter en tilførselsvalse 13 med et perforeret, centralt rør 14, som er sluttet til en limtilførsel 15, og et perifert, rundtgående skumgummilag 16, hvilket skumgummilag 16 er i anlæg mod en aftagevalse 17, der i ho-5 vedsagen er anbragt oven over tilførselsvalsen 13 og på sin side ligger an mod en påsmørevalse 18 og kan overføre lim fra skumgummilaget 16 til påsmørevalsen 18.The device comprises a feed roller 13 with a perforated central tube 14 connected to a glue supply 15 and a peripheral, circumferential foam rubber layer 16, which foam rubber layer 16 abuts against a discharge roller 17, which is disposed above the hollow 5 above. the feed roller 13 and in turn abuts on a lubricating roll 18 and can transfer glue from the foam rubber layer 16 to the lubricating roll 18.
Perforeringerne 19 i det centrale rør 14 forløber efter en 10 skruelinie på dens overflade, så lim, der tilføres gennem limtilførslen 15, kan trænge nogenlunde jævnt ud i skumgummilaget 16, hvori det fordeles jævnt gennem aftagevalsens 17 tryk mod tilførselsvalsen 13, idet aftagevalsens 17 overflade samtidigt dækkes med et tyndt limlag.The perforations 19 in the central tube 14 extend along a screw line on its surface, so that glue supplied through the glue feed 15 can penetrate roughly evenly into the foam rubber layer 16, where it is evenly distributed through the pressure of the take-up roller 17 against the feed roll 13, the surface of the take-off roller 17 at the same time covered with a thin layer of glue.
1515
Limlaget på aftagevalsens 17 overflade overføres derefter til påsmørevalsen 18 og udjævnes yderligere under denne overførsel.The adhesive layer on the surface of the removal roller 17 is then transferred to the lubricating roller 18 and further leveled during this transfer.
20 Ved siden af påsmørevalsen 18 findes en afskraber 20, der tjener til ved delvis afskrabning af limlaget på påsmørevalsen 18 at indstille limlagets tykkelse til en forud fastsat tykkelse, og med dette for øje er afskraberen justerbar i afstand i forhold til påsmørevalsen 18. Afskrabe-25 ren 20 består på kendt måde af en klinge 21, som strækker sig langs påsmørevalsens 18 overflade.20 Beside the lubricating roller 18 there is a scraper 20 which serves to adjust the thickness of the glue layer to a predetermined thickness by partially scraping the adhesive layer 18, and for this purpose the scraper is adjustable in distance from the lubricating roller 18. The clean 20 consists in a known manner of a blade 21 which extends along the surface of the lubricating roller 18.
For at indretningen ifølge opfindelsen skal kunne overføre lim til etiketter, uanset om etiketterne tilføres i den ene 30 eller den anden retning, består afskraberen 20 af to klinger 21, som forløber tangentialt på to modstående sider af påsmørevalsen 18.In order for the device according to the invention to be able to transfer glue to labels, regardless of whether the labels are applied in one or the other direction, the scraper 20 consists of two blades 21 which extend tangentially on two opposite sides of the lubricating roller 18.
De nævnte valser er indkapslet i en kappe 22, der forhin-35 drer limen i at brede sig ud i etiketteringsmaskinen. Kappen 22 er ved enderne tætnet på ikke nærmere vist måde.Said rollers are encased in a sheath 22 which prevents the glue from spreading into the labeling machine. The sheath 22 is sealed at the ends in a manner not shown.
DK 172029 B1 6DK 172029 B1 6
Transporten af lim fra en på tegningen ikke vist limtank foregår på følgende måde. Limen føres til det centrale rør 14 i tilførselsvalsen 13, hvorfra limen gennem perforerin-5 gerne 19 siver ud i skumgummilaget 16, som derved gennem-fugtes på en til dels ujævn måde, idet der vil være mest lim udfor perforeringerne 19. Denne ujævne fordeling ophæves gennem aftagevalsen 17, der er presset mod tilførselsvalsens 13 skumgummilag 16, der derefter er gennemvædet 10 ensartet med lim. Ved dette anlæg overføres der også lim til overfladen af aftagevalsen 17, der via sit samvirke med påsmørevalsen 18 overfører limlaget til denne.The transport of glue from a glue tank not shown in the drawing is carried out as follows. The glue is passed to the central tube 14 of the feed roll 13, from which the glue seeps through the perforations 5 into the foam rubber layer 16, which is thereby wetted in a somewhat uneven manner, with most glue being present on the perforations 19. This uneven distribution is lifted through the take-up roll 17 pressed against the foam rubber layer 16 of the feed roll 13, which is then uniformly soaked 10 with glue. At this plant, glue is also transferred to the surface of the take-off roller 17, which through its cooperation with the lubricating roller 18 transmits the adhesive layer thereon.
Limlaget er dog fortsat af en utilladelig tykkelse, hvorfor 15 limlaget ved en efterfølgende overførsel til objekterne, det vil sige etiketterne, ville være for tykt, så limlaget på etiketterne ikke kunne tørre tilstrækkeligt hurtigt og derfor utilsigtet kunne falde af emnerne, der er forsynet med etiketterne.However, the adhesive layer remains of an inadmissible thickness, which is why the adhesive layer upon subsequent transfer to the objects, that is, the labels, would be too thick so that the adhesive layer on the labels could not dry sufficiently quickly and therefore could inadvertently fall off the items bearing the labels.
2020
Dette reguleres ved brugen af en afskraber 20, der i form af en klinge 21 strækker sig langs påsmørevalsen 18 og skraber overflødig lim af, som derefter kan dryppe ned på tilførselsvalsen 13, så limen forbliver i indretningen uden 25 at tørre.This is controlled by the use of a scraper 20 which extends in the form of a blade 21 along the lubricating roller 18 and scrapes off any excess glue which can then drip onto the feed roller 13 so that the glue remains in the device without drying.
Afskraberen 20 udformes med to klinger 21, så indretningen ifølge opfindelsen kan anvendes, uanset om etiketterne tilføres fra den ene eller den anden retning.The scraper 20 is formed with two blades 21 so that the device according to the invention can be used, regardless of whether the labels are supplied from one direction or the other.
3030
Alle valserne i indretningen er på deres akselender forsynet med tandhjul, så valserne kan drives af en motor via en fælles tandrem.All the rollers in the device are provided with gears on their shaft ends, so that the rollers can be driven by a motor via a common toothed belt.
