I overensstammelse darmed best4r bandmaterialet vanligtvis av sana railer. En maskin, i vilken sadant material anyandes, maste, nar en sadan anaterialrulle Sr slut, stoppas en stund, och en annan rulle insattas pa en pa forhand bestamd plats, varpa. maskinen startas igen. Pa detta sStt anaste masikinen stoppas vane gang en materialrulle Sr slut. Det Sr darfOr tydligt, att den erhallna produkten blir ojanin och att resultatet blir en forsamrig av material, saint materialforlust och tidsforlust, och olika andra ekonomiska °eh tekniska olagenheter. Inventors: K Ota and K Aoki Priority requested on December 5, 1958 (Japan) The present flare refers to a device which allows a continuous workflow, as in a batch of continuous rollers (or spools) with continuous replacement of individual rollers by mechanical splicing of the ends of a material wound on a roll with the initial end of the material wound on the following roll without the work process having to be broken in the machine in which the strip material is used. % dant tape material Sr e.g. metal foil, popper (including waxed popper, foil-coated paper, etc.). Wrapped web material such as metal foil, popsicles, film, etc., which are to be treated, are generally of limited length, since the weight is limited. Accordingly, the strip material usually consists of sane rails. A machine in which such a material is required, when such a roll of material is exhausted, is stopped for a while, and another roll is inserted in a predetermined place, warp. the machine restarts. In this way, the only machine is usually stopped when a roll of material ends. It is therefore clear that the product obtained will be ojanin and that the result will be a combination of materials, saint material loss and loss of time, and various other economic and technical irregularities.

En maskinram 1 (vilken i verkligheten Sr konstruerad sasom ett par delar, som stracka sig parallellt med varandra, varvid alla ax-lama, som namnas i det foljande, are anardnade anellan dessa nada parallella delar, ritningen Sr den ena av dessa hada delar borttagen) her an nedat utskjutande del 2, vilken skall uppbara axeln 3. Denna axel 3 har en dubbelarmad havstang 6 forsedd rued axlar 4, 5 fOr att uppbara var sin rulle vid vardera anden av havstangen 6, varvid ha.vstangen 6 insattes pa axeln 3 genom centrumhalet 7. A machine frame 1 (which in reality Sr is constructed as a pair of parts extending parallel to each other, all the shafts, which are mentioned in the following, being arranged in these nad parallel parts, the drawing Sr one of these had parts removed) ) here a downwardly projecting part 2, which is to support the shaft 3. This shaft 3 has a double-armed sea rod 6 provided with red shafts 4, 5 to support each roll at each end of the sea rod 6, the sea rod 6 being inserted on the shaft 3 through the center tail 7.

Den bockade stangen 9 oda aranen 10 aro svangbart upphangda pa axeln 8, vilken les av en lamplig, ej visad, stationar del pa ovre delen av maskinramen. En axel 11 fOrbunden med en ej visad mekanism for svangming av den bockade stangen 9 Sr lagrad I den ,bockade delen av derma stang, och en mottagarrrulle 12 Sr roterbart lagrad i den fria anden av ,stangen 9, varvid, sasora visas i fig. 5, rullens 12 axel 13 Sr ihalig, och det genomgaende halet 14 1 deama axel star i forbindelse med en Fang slits 15 i axialled i raottagarrullens 12 mantelyta. Den °Puma ytan 16 utformas t. ex. genom lampligt bred pragling bakom slitsen 15 i rullens 12 rotationsriktning (sasom visas med en pil pa nit- 2— — ningen). En kontakt 17 t. ex. en mikrokontakt är anordnad vid rullens 12 ena ande och en paverkningsknapp 18 pa kontakten 17 Sr lampligt framskjuten frau rullens periferiyta. The bent rod 9 or the arane 10 are pivotally suspended on the shaft 8, which is read by a lamp, not shown, stationary part on the upper part of the machine frame. A shaft 11 connected to a mechanism (not shown) for pivoting the bent rod 9 is mounted in the bent part of this rod, and a receiving roller 12 is rotatably mounted in the free spirit of the rod 9, wherein, as shown in FIG. 5, the shaft 13 of the roller 12 is sloping, and the through-tail 14 in the same shaft is connected to a catch slot 15 in the axial direction in the circumferential surface of the receiver roller 12. The ° Puma surface 16 is designed e.g. by suitably wide embossing behind the slot 15 in the direction of rotation of the roller 12 (as shown by an arrow on the rivet). A contact 17 e.g. a micro-contact is arranged at one end of the roller 12 and an actuating button 18 on the contact 17 is suitably projected from the peripheral surface of the roller.

Vid armens 10 fria dude uppbares roterhart en tryckrulle 21 genom stadorganet 19, med fjadern 20 insatt mellan amen 10 och stodorganet 19. Tryckrullen 21 Sr gjord av gummi, papper eller nagot an.nat elastiskt amne, eller har atminstone pa sin. yttersida en sadan belaggning. Ett skarverktyg 22 Sr fast vid stodorganet 19, sa att dess egg 23 kan riktas mot mottagarrullen 12 mitt emot tryckrullen 21. At the free dude of the arm 10, a pressure roller 21 is rotatably supported through the city member 19, with the spring 20 inserted between the frame 10 and the support member 19. The pressure roller 21 is made of rubber, paper or some other elastic blank, or at least has its own. surface such a coating. A splice tool 22 is attached to the support member 19 so that its edge 23 can be directed towards the receiving roller 12 opposite the pressure roller 21.

Vidare Sr maskinramen. 1 forsedd med en uppatriktad arm 24, pa. vilken en. roterbar ledrulle 26 Sr anordnad pa en axel 25. Further Sr the machine frame. 1 provided with an upright arm 24, pa. which one. rotatable articulated roller 26 Sr arranged on a shaft 25.

Anordningen enligt ovan beskrivna konstruktion verkar pa foljande satt: Med hanvisning till fig. 1 ledes forst ett bandmaterial 27, som bildar en rulle A, genum ett mellanrum mellan rnottagarrullen 12 och tryckrullen 21, vilka aro atskilda frail varandra. The device according to the construction described above operates in the following way: Referring to Fig. 1, a strip material 27, which forms a roller A, is first guided through a space between the receiver roller 12 and the pressure roller 21, which are separated from each other.

Pet drages framat pa ett lamplagt satt och anvandes i en maskin. I ett lage som detta, innan materialet 27 avrullats Sr rullen A liten, varvid en annan rulle B, som skall anvandas darefter Sr anordnad pa en axel 5 mitt emot den axel, pa vilken rullen A Sr monterad. Begynnelseanden till materialet 27', soun bildar rullen B, bringas darafter att fasta vid mottagarrullen 12 genom paverkan av ett sag-organ, som star i forbindelse med slitsen 15 genom dot genomgaende halet 14 i mottagarrullen 12. Samtidigt darmed ror sig den hoekade stangen 9 fran sitt lage i fig. 1 gradvis till laget i fig. 2 och narmar sig vidare tryckrullen 21 tvArs over detta lage i fig. 2 genom paverkan av en ,drivrnekanism for axeln 11. Pet is pulled forward on a lamped set and used in a machine. In a layer like this, before the material 27 is unrolled, the roller A is small, whereby another roller B, which is to be used thereafter, is arranged on a shaft 5 opposite the shaft on which the roller A is mounted. The initial spirit of the material 27 ', which forms the roller B, is then fastened to the receiver roller 12 by the action of a saw member which communicates with the slot 15 through the dot through the hole 14 in the receiver roller 12. At the same time the angled rod 9 moves. from its bearing in Fig. 1 gradually to the bearing in Fig. 2 and further approaches the pressure roller 21 across this bearing in Fig. 2 by the action of a drive mechanism for the shaft 11.

Omedelbart innan materialet 27 pa rullen A har anvants, kommer mottagarrullen 12 i kontakt Tried tryckrullen 21 sasom i fig. 3, varvid dessa rullar 12, 21 hada rotera niir de ingripa med varandra, eftersom materialet 27 meddelas en. viss dragspanning i den maskin, som matas, sasom beskrivits tidigare. Immediately before the material 27 on the roller A has been used, the receiving roller 12 comes into contact with the pressure roller 21 as in Fig. 3, these rollers 12, 21 having rotated before they engage with each other, since the material 27 is communicated to one another. certain tensile stress in the machine being fed, as previously described.

I detta agonblick, nar en paverkande knapp 18 pa. kontakten 17 inpressas av tryckrullen 21, pa grund av kontaktens 17 lage enligt fig. 5 och 6, barjar begynnelseanden till materialet 27, som kommer frau rullen A, en rarelse langs materialet 27' frail mottagarrullen 12, forutsatt, att rotationsrarelsen har anordnats sa, att sugorganet kan stoppas. Men eftersom mottagarrullen Sr forsedd med den. ojamna ytan 16, sasona tidigare namints, skarvas materialen 27 och 27' under Overlappning, varpa materialet 27 avskares av eggen 23 pa. skarverktyget 22, vilket narmar sig materialet 27, till ARM av fOrskjutning av tryckrullen 21 (se fig. 4). I Overensstammelse dar- med svanges darefter rullen B, bildad av materialet 27' till rullens A lage, f6r att fortsatta arbetet. I fig. 7 'visas en latt modifika- lionkonstruktionen av mottagarrullen 12, varigenom en gripanordning 28 anvandes i stallet for ,sugorganet for att gripa begynnelseariden. till materialet. Aven i detta fall paverkas gripmekanismen 28 elektriskt med hjalp av MIKROkontaktern 17. A andra sidan kan i praktiken. en varmeforeningsmetod anordnas for att skarva de bada materialen i stallet far tandingrepp genom den ojamna ytan 16, varigenom ett upphettningsorgan inslutes i mottagarrullen 12, och samtidigt behovs en film av termoplastisk syntetisk harts for att utgora atminstone begynnelseanden p5. materialet. At this moment, an affecting button reaches 18 pa. the contact 17 is pressed by the pressure roller 21, due to the position of the contact 17 according to Figs. 5 and 6, the initial end of the material 27 coming from the roller A begins to move along the material 27 'from the receiving roller 12, provided that the rotation movement has been arranged so, that the suction means can be stopped. But since the receiving roller Sr provided with it. uneven surface 16, sasona previous namints, the materials 27 and 27 'are spliced under overlap, the warp material 27 is cut off by the edge 23 pa. the splice tool 22, which approaches the material 27, to the ARM by displacing the pressure roller 21 (see Fig. 4). In accordance with this, the roller B, formed by the material 27 'to the layer A of the roller A, is then pivoted to continue the work. Fig. 7 'shows a light modification construction of the receiving roller 12, whereby a gripping device 28 is used in the stable for, the suction means for gripping the initial arid. to the material. Even in this case, the gripping mechanism 28 is electrically actuated with the aid of the MICRO contactor 17. On the other hand, in practice. a heat joining method is provided for splicing the bath materials instead of tooth engagement through the uneven surface 16, thereby enclosing a heating means in the receiving roller 12, and at the same time a film of thermoplastic synthetic resin is required to form at least the initial spirit p5. the material.
