Description

151465 5 Opfindelsen angår en fremgangsmåde og et apparat til anbringelse af beskyttelsesfolie på bøger eller hæfter.This invention relates to a method and apparatus for applying protective foil to books or booklets.

Bøger eller hæfter, der anvendes ofte, eller som 10 læses eller gennemses af mange personer, beskyttes ofte med en eller anden form for ekstra indbinding.Books or booklets that are frequently used or that are read or read by many people are often protected with some form of extra binding.

Por at undgå at skulle føre teksten fra selve bogbindet ud på det ekstra omslag, anvendes gennemsigtigt papir eller plastmateriale til den ekstra indbinding.To avoid having to carry the text from the book binding itself onto the extra cover, transparent paper or plastic material is used for the extra binding.

15 Visse typer hæfter er desuden ikke indbundet solidt nok til hyppig brug, f.eks. tegneseriehæfter, og skal sådanne udlånes på bibliotek eller læsesal, går bindet hurtigt i stykker. De beskyttes derfor næsten altid med en klar beskyttelsesfolie ofte af 20 en selvklæbende type.15 Certain types of booklets are also not hard-bound sufficiently for frequent use, e.g. comic booklets, and should be borrowed at the library or reading room, the volume breaks quickly. They are therefore almost always protected with a clear protective foil often of a self-adhesive type.

Det er et stort, manuelt arbejde at lægge beskyttelsesfolie på bøger, især når man anvender den selvklæbende type, hvilket man ofte ønsker, fordi denne 25 type styrkemæssigt og slidmæssigt har mange fordele.It is a great manual work to put protective foil on books, especially when using the self-adhesive type, which is often desired, because this type of strength and wear has many advantages.

Først skal et passende stykke folie afskæres eller tilklippes, og herefter skal en dækfolie over klæbesiden fjernes. Herefter sættes folien på bogen. De selvklæbende folier, der anvendes, er meget stærkt 30 klæbende, så monteringen skal være korrekt første gang, idet det er umuligt at fjerne folien igen uden at ødelægge bogen. Det er også et problem at undgå, at man punktvis indespærrer luft mellem folien og bogen eller hæftets oprindelige omslag, hvilken inde- 151465 2 1 spærrede luft ville medføre blærer på bindet. Ved manuel pålægning kræver det faktisk en meget stor rutine og god fingerfærdighed at lægge en selvklæbende beskyttelsesfolie på en bog eller et hæftebind, helt 5 uden luftblærer. En rutineret medarbejder kan derfor maksimalt lægge beskyttelsesfolie på 30 bøger eller hæfter per time.First, a suitable piece of foil must be cut or cut, and then a cover foil over the adhesive side must be removed. Then put the foil on the book. The self-adhesive foils used are very strong adhesive, so the mounting must be correct the first time, as it is impossible to remove the foil again without damaging the book. It is also a problem to avoid puncturing air temporarily between the foil and the book or the original cover of the booklet, which entrapped air would cause blisters on the bandage. In manual application, applying a self-adhesive protective foil to a book or booklet, 5 without air bubbles, requires a very large routine and good dexterity. A skilled employee can therefore place a maximum of 30 sheets or booklets per hour on a protective film.

Formålet med opfindelsen er at angive en fremgangsmåde 10 og et apparat til anbringelse af beskyttelsesfolie på bøger eller hæfter, så man både får en sikker og fejlfri pålægning af folien, men samtidig opnår en væsentligt øget hastighed i pålægningen. Dette opnås ved at gå frem som angivet i krav 1's kendeteg-15 nende del, f.eks. under anvendelse af et apparat, som angivet i krav 4's kendetegnende del. Man får hermed automatiseret den manuelle proces, så et apparat kan lægge folie på bøger med en hastighed af 300 bøger per time. Ved at anvende valser, som anbrin-20 ger folien på bogens eller hæftets ydersider, fås altid en jævn og ensartet pålægning helt uden luftblærer.The object of the invention is to provide a method 10 and an apparatus for applying protective foil to books or booklets so as to obtain both a safe and error-free application of the foil, but at the same time obtaining a substantially increased speed in the application. This is achieved by proceeding as set forth in the characterizing part of claim 1, e.g. using an apparatus as claimed in the characterizing part of claim 4. The manual process is thus automated, so that an appliance can put foil on books at a rate of 300 books per hour. By using rollers which apply the foil to the outside of the book or booklet, a uniform and uniform coating is always obtained without any air bubbles.

Ved at anvende et apparat, som angivet i krav 51 s 25 kendetegnende del, opnår man, at apparatet kan lægge folie på bøger eller hæfter med forskellig tykkelse, uden at man skal foretage indgreb i apparatet og efterindstille dette efter bogens tykkelse og øvrige dimensioner.By using an apparatus as defined in claim 51, s 25, it is achieved that the apparatus can apply foil to books or booklets of different thickness, without having to intervene in the apparatus and adjust it according to the book's thickness and other dimensions.

Ved at gå frem som angivet i krav 21 s kendetegnende del, f.eks. under anvendelse af et apparat, som angivet i krav 6's kendetegnende del, opnår man, at de samme midler anvendes til både at fastholde det klar- 3 151465 1 gjorte foliestykke og til at lægge foliestykket på den næste bog. Hele fremgangsmåden ved pålægning af folien sker fuldautomatisk, idet apparatet afmåler og afskærer et passende stykke folie under hensyntagen 5 til både tykkelse og størrelse af bog eller hæfte.By proceeding as claimed in claim 21, the characteristic part, e.g. using an apparatus as claimed in the characterizing part of claim 6, it is obtained that the same means are used to both hold the prepared film piece and to place the film piece on the next book. The entire process of applying the foil is fully automatic, the apparatus measuring and cutting a suitable piece of foil, taking into account 5 for both the thickness and size of the book or booklet.

Skal der bruges et indslag, hvilket man almindeligvis anvender, afmåles folien blot med passende overmål, f.eks. 2 x 15 mm til bogens eller hæftets modsat ryggen værende kanter, idet der normalt ikke anvendes 10 indslag om bogens vinkelret på ryggen værende kanter. Indslaget slås manuelt ind efter foliepålægningen er fuldført.If a wrap is to be used, which is commonly used, the foil is simply metered with appropriate overlays, e.g. 2 x 15 mm to the edges of the book or booklet opposite the back, normally 10 notches on the book's perpendicular to the back edges are used. The wrap is manually wrapped after the foil coating is complete.

Ved at gå frem som angivet i krav 3's kendetegnende 15 del, f.eks. under anvendelse af et apparat, som anvendes i krav 7's kendetegnende del, kan man også lægge beskyttelsesfolie på bøger eller hæfter, hvor omslaget er meget sart. Skal der f.eks. lægges folie på indbundne bøger, hvor omslaget ikke er ridsefast, kan 20 man ikke nøjes med at fremføre og positionere bøgerne på et almindeligt transportbånd, idet mindre sandskorn eller anden snavs kan give ridser på bindet. Ved at anvende en luftpude ifølge opfindelsen undgår man fuldstændigt at ridse eller på anden måde beskadi-25 ge bindet, inden der bliver pålagt beskyttelsesfolie.Proceeding as set forth in the characterizing part of claim 3, e.g. using an apparatus used in the characterizing part of claim 7, protective film can also be applied to books or booklets where the cover is very delicate. Should, for example, If foil is placed on hardcover books where the cover is not scratch resistant, it is not enough to carry and position the books on a regular conveyor belt, as less sand grains or other dirt can cause scratches on the binding. By using an airbag according to the invention, it is completely avoided to scratch or otherwise damage the binder before applying protective foil.

Apparatet til pålægning af beskyttelsesfolier er fortrinsvis udformet som angivet i krav 8's kendetegnende del. Herved kan man på enkel måde indstille 30 apparatet til bøger eller hæfter af forskellig tykkelse. Apparatet er fortrinsvis konstrueret således, at højdeindstillingen sker ud fra måling af den næste bogs tykkelse.The apparatus for applying protective foils is preferably formed as defined in the characterizing part of claim 8. Hereby, the apparatus can be easily adjusted to books or booklets of different thicknesses. The apparatus is preferably constructed such that the height adjustment is made from the measurement of the thickness of the next book.

151465 4 1 Opfindelsen forklares herefter nærmere under henvisning til tegningen, der skitsemæssigt viser et lodret plant snit gennem en udførelsesform for opfindelsen.The invention will now be explained in more detail with reference to the accompanying drawings, which show a vertical plan section through an embodiment of the invention.

5 På tegningen angiver 4 et bord eller et lignende maskinstativ, der bærer hele apparatet til foliepålægningen. I venstre side er vist et magasin med bøger 1, hvilket magasin er således indrettet, at man kan indstille det til bøger af forskellig størrelse.5 In the drawing, 4 indicates a table or similar machine rack supporting the entire apparatus for the foil coating. On the left is a magazine with books 1, which magazine is arranged so that it can be set for books of different sizes.

10 Magasinet er i øvrigt af almindelig kendt type og skal ikke omtales nærmere. Fra bunden af magasinet udleveres bøgerne enkeltvis af en almindelig kendt udleveringsmekanisme til et endeløst transportbånd 3, der altid kører i den med pile viste retning.10 The magazine is otherwise of a generally known type and does not need to be mentioned in more detail. From the bottom of the magazine, the books are delivered individually by a commonly known dispensing mechanism to an endless conveyor belt 3, which always runs in the direction indicated by arrows.

15 Bøgerne er anbragt med ryggen mod højre, og udleveres således også til båndet 3 med ryggen mod højre. Det er således nødvendigt, at bøgerne 1 altid lægges i magasinet med ryggen i en bestemt retning, men det er til gengæld underordnet, om bogens forside 20 eller bagside vender opad.The books are arranged with the back to the right, and thus are also delivered to the band 3 with the back to the right. Thus, it is necessary that the books 1 always be placed in the magazine with their backs in a certain direction, but it is in turn inferior whether the front of the book 20 or the back of the book faces upwards.

Idet en bog eller et hæfte udleveres, møder den en tykkelseaftaster 2, der måler den netop udleverede bogs tykkelse. Transportbåndet 3 er forsynet med 25 et antal huller eller dyser 14 for trykluft, så der dannes en luftpude mellem bogen 5 og båndet 3. Man kan således flytte eller skubbe bogen 5 til korrekt position på båndet, uden at snavs, sand eller ujævnheder på båndet ridser bogbindet.As a book or booklet is handed out, it encounters a thickness scanner 2 that measures the thickness of the book just released. The conveyor belt 3 is provided with a plurality of compressed air holes or nozzles 14 to form an air cushion between the book 5 and the belt 3. Thus, the book 5 can be moved or pushed to the correct position on the belt without any dirt, sand or unevenness on the belt. scratches the book binding.

En mikrokontakt eller en anden form for aftastnings-organ 6 reagerer, så snart en bog 5 passerer, og herved aktiveres en luftcylinder 26, der betjener et sidestyr, som anbringer bogen 5 korrekt på båndet, 5 151465 1 og samtidig hermed måles ryggens længde. Længere fremme på båndet 3 findes en yderligere mikrokontakt eller en anden form for aftastningsorgan 9. Aftastningsorganerne 6 og 9 anvendes til styring af trans-5 portbåndet 3's drivmotor, så bøgerne 5 og 5' fremføres i en passende takt og med passende afstand. Aftastningsorganerne 6 og 9 anvendes desuden til måling af bogens bredde. Bogens bredde kan også konstateres ved måling på bogmagasinet/ der udleverer bogen til 10 båndet 3.A microswitch or other type of sensing means 6 responds as soon as a book 5 passes, thereby activating an air cylinder 26, which serves a side guide which correctly places the book 5 on the tape, and at the same time measures the length of the back. Further on the band 3 is a further microswitch or other form of sensing means 9. The sensing means 6 and 9 are used to control the drive belt 3's drive motor so that the books 5 and 5 'are conveyed at a suitable rate and at a suitable distance. The scanning means 6 and 9 are additionally used for measuring the width of the book. The width of the book can also be ascertained by measuring on the book magazine / delivering the book to the 10 band 3.

Samtidig med at en bog 5' ' er nået frem til selve pålægningspositionen, er foliemekanismen blevet klargjort. Fra en forrådsrulle føres en foliebane 12 15 med dækfolie til en hovedvalse 20, der har en ensidig omløbsretning som vist. Her møder foliebanen 12 straks en fremtræksvalse 15, der trækker foliebanen 12 frem og afleverer dækfolien 11 til et magasin herfor.At the same time that a book 5 '' has reached the actual positioning position, the film mechanism has been made clear. From a supply roll, a foil web 12 15 with cover foil is fed to a main roller 20 having a unilateral direction of rotation as shown. Here, the foil web 12 immediately encounters an advance roller 15 which pulls the foil web 12 forward and delivers the cover foil 11 to a magazine therefor.

Med pile er angivet både foliebanen 12 og dækf olien 20 11's bevægelsesretning. Beskyttelsesfolien føres videre af en valse 16, der desuden renskærer foliekanten i korrekt bredde efter den tidligere omtalte måling af bogens højde. 1 2 3 4 5 6Arrows indicate both the film path 12 and the direction of travel of the oil 20 11. The protective foil is further guided by a roller 16 which further cleans the foil edge at the correct width after the previously mentioned measurement of the height of the book. 1 2 3 4 5 6

Af en førevalse 17 ledes folien gennem en ikke vist 2 åbning i bordet 4 ned til en fremtræknings- og holde 3 valse 21. Holdevalsen 21, der f.eks. kan være en 4 sugevalse, griber foliekanten og fastholder og trækker 5 i denne, idet valsen 21 på dette trin har samme om- 6 løbsretning som hovedvalsen 20. Ud fra resultatet af den forudgående måling af bogens tykkelse og bredde styres et skæreværktøj 18, så der afskæres et stykke folie 22 tilstrækkeligt stort til at lægges på den bog 51 ', som er nået frem til foliepålægningsmekanis- 6 151465 1 men. Det klargjorte og renskårne foliestykke 22 er nu fastholdt og udspændt mellem valserne 20 og 21, der begge står stille, idet en holdevalse 19 trykker folien mod valsen 20, og idet folien suges fast til 5 valsen 21. Folien står nu klar til pålægning, idet klæbesiden vender mod ryggen af den bog 51', som nu skal pålægges beskyttelsesfolie.From a lead roller 17, the foil is guided through a not shown 2 opening in the table 4 down to a projection and hold 3 roller 21. The holding roller 21, e.g. may be a 4 suction roller, grasping the foil edge and holding and pulling 5 therein, the roller 21 at this stage having the same direction of rotation as the main roller 20. From the result of the prior measurement of the book's thickness and width, a cutting tool 18 is controlled so that a piece of foil 22 is cut sufficiently large to be placed on the book 51 'which has been obtained for the foil application mechanism. The prepared and clean cut film piece 22 is now retained and stretched between rollers 20 and 21, both standing still, a holding roller 19 pressing the film against the roll 20, and the film being sucked to the roll 21. The film is now ready for application, the adhesive side faces the back of the book 51 'which is now to be coated with protective foil.

Bogen 511 føres mod folien af transportbåndet 3 og 10 ind mellem valserne 20 og 21, hvoraf sidstnævnte nu drives med modsat omløbsretning, så foliestykket 22 valses på bogen 5'1 fra ryggen mod kanten. Et andet transportbånd 8 overtager nu den videre transport af bogen 5' ’ 1 videre til position 51'11, hvor 15 bogen afleveres til viderebehandling, som f.eks.The book 511 is inserted against the foil of the conveyor belt 3 and 10 between the rollers 20 and 21, the latter of which is now driven in the opposite direction of rotation, so that the foil 22 is rolled on the book 5'1 from the back to the edge. Another conveyor belt 8 now takes over the further transport of the book 5 '' 1 to position 51'11, where the book is handed over for further processing, such as e.g.

består i, at et eventuelt overmål af folie på bogens modsat ryggen værende kanter slås ind manuelt.consists of manually wrapping any excess film on the opposite edges of the book.

Hovedvalsen 20 med hjælpevalserne 15, 16, 17 og 19 20 og skæreværktøjet 18 er anbragt på en holder 10, som kan drejes omkring et ophængningspunkt 25, så alle de nævnte dele kan forskydes samlet, som angivet ved dobbeltpilen ud for holderen 10. Afstanden mellem hovedvalsen 20 og holdevalsen 21 reguleres således 25 ved at hæve og sænke holderen 10. Holderen 10 hæves og sænkes af en luftcylinder 13 med stempel, der gennem en arm griber fat i holderen 10. Afstanden mellem valserne 20 og 21 indstilles efter målingen af bogens tykkelse, så valserne altid påvalser folie-30 stykket 22 på bogen 5'' med et bestemt tryk, uafhængigt af bogens tykkelse. Valseafstanden indstilles således automatisk, så den altid passer til den næste bog, der skal have folie påvalset.The main roller 20 with the auxiliary rollers 15, 16, 17 and 19 20 and the cutting tool 18 is arranged on a holder 10 which can be rotated about a suspension point 25 so that all said parts can be displaced together, as indicated by the double arrow next to the holder 10. The distance between Thus, the main roller 20 and the holding roller 21 are adjusted 25 by raising and lowering the holder 10. The holder 10 is raised and lowered by an air cylinder 13 with a piston which grips the holder 10 through an arm. The distance between the rollers 20 and 21 is adjusted according to the measurement of the book thickness. , so that the rollers always roll the foil 30 piece 22 on the book 5 '' with a certain print, regardless of the thickness of the book. Thus, the spacing distance is automatically set so that it always fits the next book that must have foil rolled.

151465 7 1 Mellem bordet 4 eller transportbåndet 8 og holderen 10 er der anbragt en mikrokontakt 23 eller et lignende aftastningsorgan, som aftaster O-stillingen, så valserne 20 og 21 ikke trykkes hårdt mod hinanden, når 5 apparatet ikke lægger folie på en bog.Between the table 4 or the conveyor belt 8 and the holder 10, a microswitch 23 or a similar sensing means is placed which senses the O-position so that the rollers 20 and 21 are not pressed hard against each other when the apparatus does not put foil on a book.

Under de to transportbånd 3 og 8 kan der blive plads til at anbringe forskelligt hjælpeudstyr i form af f.eks. en trykluftpumpe og en vacuumpumpe 7 med behol-10 der for henholdsvis trykluft og vacuum, og et eller flere skabe 24 med det nødvendige udstyr til styring og regulering af apparatets enkelte funktioner. Desuden kan drivmotorerne til transportbåndene anbringes her. De enkelte valser og hjælpevalser kan drives 15 af mindre elektromotorer eller af trykluftmotorer.Under the two conveyor belts 3 and 8, there may be space to place different auxiliary equipment in the form of e.g. a compressed air pump and a vacuum pump 7 with containers 10 for compressed air and vacuum respectively, and one or more cabinets 24 with the necessary equipment for controlling and regulating the individual functions of the apparatus. In addition, the drive motors for the conveyor belts can be placed here. The individual rollers and auxiliary rollers can be driven by smaller electric motors or by compressed air motors.

Valserne 15, 16, 17 og 19 og eventuelt også valserne 20 og 21 samt skæreværktøjet 18 er udformet således, at den stærkt klæbende folie ikke hæfter herpå, f.eks.The rollers 15, 16, 17 and 19 and optionally also the rollers 20 and 21 as well as the cutting tool 18 are designed so that the highly adhesive foil does not adhere thereto, e.g.

20 ved at de er belagt med Teflon^ eller lignende afvisende belægning. Valserne 20 og 21 er fortrinsvis gummivalser.20 in that they are coated with Teflon ^ or similar repellent coating. The rollers 20 and 21 are preferably rubber rollers.

Styreskabet 24 styrer apparatets forskellige funktio-25 ner på almindelig kendt måde ud fra aftastning af bøgernes positioner og størrelser, idet styringen og reguleringen foregår på almindelig kendt måde ved elektriske komponenter eller trykluftkomponenter.The control cabinet 24 controls the various functions of the apparatus in a generally known manner based on scanning of the books' positions and sizes, the control and regulation being carried out in a generally known manner by electrical components or compressed air components.
