455 496 10 15 20 25 30 35 _2- ningen och matas till en tryckcylinder i maskinen. Under accele- rationsförloppet görs det i arkets matningsriktning bakomliggande klâmrullparet overksamt genom att rullarna säras frân varandra så snart arkets främre kant har nått det framförliggande klåmrullparet så att nästa ark kan n8 märken. Det därefter verksamma klåmrullparet accelererar arket till en hastighet, som år större än tryckcylinderns periferihastighet, detta för att arkets främre kant säkert skall nå cylinderns märke. Cylinderns gripare övertar den fortsatta transport- en av arket i maskinen under det att rullarna i det nämnda framför- liggande klämrullparet likasâ säras frân varandra. Vid denna kända arkmatning uppnås visserligen att arken transporteras tätt följda av varandra genom en dubblerad anordning av klämrullparen och samspelet mellan dem. Emellertid ankommer det ej pâ den exakta positionering av arkets framkant relativt tryckcylindern eftersom toleransen då fram- kanten när cylinders märken jämnas ut genom arkets förhöjda transporthastighet relativt cylinderns periferihastighet. Dessutom medför de dubbla klåmrullparen och deras våxelvisa samverkan att styrningen av maskinen blir kostsam och känslig för störningar. Ändamålet med föreliggande uppfinning är att åstadkomma en anordning av det inledningsvis nämnda slaget, vilken trots hög arkkapacitet har lâg förslitning och åstadkommer en noggrann matning med för varieran- de arklångd inställbar.synkron hastighet relativt maskinhastigheten. 455 496 10 15 20 25 30 35 _2- and is fed to a pressure cylinder in the machine. During the acceleration process, the clamping roller pair underlying the sheet feed direction is rendered inactive by separating the rollers from each other as soon as the leading edge of the sheet has reached the leading clamping roller pair so that the next sheet can n8 marks. The subsequently acting clamping roller pair accelerates the sheet to a speed which is greater than the peripheral speed of the printing cylinder, so that the leading edge of the sheet will safely reach the mark of the cylinder. The gripper of the cylinder takes over the continued transport of the sheet in the machine while the rollers in the said present clamping roller pair are also separated from each other. In this known sheet feeding, it is admittedly achieved that the sheets are transported closely followed by each other by a doubled arrangement of the clamping roller pairs and the interaction between them. However, it does not depend on the exact positioning of the leading edge of the sheet relative to the printing cylinder because the tolerance then the leading edge when the cylinder marks are leveled by the increased transport speed of the sheet relative to the peripheral speed of the cylinder. In addition, the double clamp roller pairs and their alternating interactions mean that the control of the machine becomes costly and susceptible to disturbances. The object of the present invention is to provide a device of the kind mentioned in the introduction, which, despite high sheet capacity, has low wear and provides an accurate feed with a synchronous speed adjustable for varying sheet length relative to the machine speed.
Enligt uppfinningen åstadkommas detta med en anordning hos vilken accelerationsanordningen uppvisar en accelerationsvals vars drivning sker med en frân transportvalsens drivning separerad varvtalsstyrd drivmotor, mot vilken accelerationsvals de ark som skall accelereras pressas av en synkroniseringsrulle. §n anordning enligt uppfinningen uppvisar inga delar hos vilka man kan vänta förslitning, såsom t.ex en koppling eller liknande: Den kan köras med utomordentligt hög hastighet. När bakkanten av ett ark, som transportvalsen gripit tag i, har passerat accelerationsvalsen, sänker sig synkroniseringsvalsarna ned mot den fortfarande stilla- stående accelerationsvalsen. Det nya arket, som ligger an mot de främre märkena, kläms fast mellan accelerationsvalsen och synkronise- _ 10 15 20 25 30 35 455 496 -3- ringsrullen. En av enturaxeln driven rotationsgivare ger start impulsen för accelerationsvalsen, vilken accelererar detta ark frân stillestând till maskinhastighet.According to the invention, this is achieved with a device in which the acceleration device has an acceleration roller whose drive takes place with a speed-controlled drive motor separated from the drive of the drive roller, against which acceleration roller the sheets to be accelerated are pressed by a synchronizing roller. The device according to the invention has no parts in which wear can be expected, such as, for example, a coupling or the like: It can be driven at an extremely high speed. When the trailing edge of a sheet which the transport roller has grasped has passed the acceleration roller, the synchronizing rollers descend towards the still stationary acceleration roller. The new sheet, which abuts the front marks, is clamped between the accelerator roller and the synchronizing roller. A rotary sensor driven by the enturaxle provides the starting impulse for the acceleration roller, which accelerates this sheet from standstill to machine speed.
Enligt ett föredraget utförande av uppfinningen styrs maximivarvtalet för accelerationsvalsens drivmotor av transportvalsen. Denna hastig- het kan Lex avkännas elektroniskt. Företrädesvis motsvarar därvid vidden hos den spalt, som bildas mellan arktransportvalsen och acce- lerationsvalsen med resp samverkande rullar högst den minsta Längden hos arken, vilka skall transporteras och minst den för acceleration till maskinhastigheten dubbla sträckan.According to a preferred embodiment of the invention, the maximum speed of the drive motor of the acceleration roller is controlled by the transport roller. Lex can be sensed electronically at this speed. Preferably, the width of the gap formed between the sheet transport roller and the acceleration roller with respective cooperating rollers corresponds at most to the minimum length of the sheets to be transported and at least twice the distance for acceleration to the machine speed.
Enligt ytterligare ett föredraget utförande av uppfinningen motsvarar avståndet mellan främre märket och spalten mellan arktransportvalsen och mottrycksrullarna åtminstone den sträcka, som erfordras för acce- lerationen till maskinhastigheten. Denna sträcka bör åtminstone uppgå till hälften av den sträcka, som tidigare ark tillryggalägger under accelerationen till maskinhastighet.According to a further preferred embodiment of the invention, the distance between the front mark and the gap between the sheet transport roller and the counter-pressure rollers corresponds to at least the distance required for the acceleration to the machine speed. This distance should be at least half the distance that previous sheets travel during the acceleration to machine speed.
Uppfinningen förklaras närmare med hänvisning till ritningen, som visar ett utförandeexempel. Pâ ritningen visar: Fig 1 schematiskt en sidovy av en kaschermaskin med en matningsanord- ning enligt uppfinningen; Fig 2 schematiskt en frontvy av anläggningen enligt fig 1 och Fig 3 schematiskt en förstorad sidovy av endast matningsanordningen.The invention is explained in more detail with reference to the drawing, which shows an embodiment. In the drawing: Fig. 1 schematically shows a side view of a cashmere machine with a feeding device according to the invention; Fig. 2 schematically shows a front view of the plant according to Fig. 1 and Fig. 3 schematically an enlarged side view of only the feeding device.
Från en arkläggare 3 matas ark 4 via ett transportband 5, som tillhör en generellt med 6 betecknad matningsanordning, varifrån de matas till själva kaschermaskinen 7 i vilken arken kascheras på en bärande bana 8. Från arklåggaren 3 transporteras arken 4 delvis täckande varandra. Det främsta arket 4" kommer inriktat fram till anliggning mot ett främre märke 9. Efter det bakkanten av det utgående arket 4' (fig 3) passerat accelerationsvals 10, sänks synkroniseringsrullar 11 ned pâ den stillastående accelerationsvalsen 10 och klämmer därvid fast arket 4" mellan sig. En av arkläggarens 3 enturaxel 12 driven rotationsgivare 13 (fig 2) ger en startimpuls för accelereringen av arket 4" som ligger an mot främre märket 9.0ärvid fälls samtidigt 10 15 20 25 455 496 ...ÅF detta ner. Accelereringen och samtidigt nedfällningen av främre märket 9 utlöses alltså vid ett noggrannt fastlagt gradtal hos entur- axeln 12. Under arkets 4" acceleration tillryggalågger det tidigare av en arktransportvals 14 med mottrycksrulle 15 omhändertagna arket 4' sträckan s med konstant maskinhastighet. Härunder accelereras arket 4" från noll till full maskinhastighet och transporteras härvid sträckan s/2 så att det i det ögonblick då maskinhastigheten upp- nåtts, med sin framkant kommer att ligga precis mot bakkanten av det tidigare arket 4'. Styrningen av accelerationen hos accelerations- valsens 10 drivmotor 16 sker elektroniskt på i och för sig känt sätt via en rotationsgivare 17 i beroende av den med maskinhastighet via kaschermaskinens 7 transmissionsdrivning 18 drivna arktransportvalsen 14 via ett styrorgan 20, varvid en rotationsgivare 19 likaså matar in arktransportvalsens 14 maskinhastighet i styrorganet 20. Enturaxeln 12 drivs likaså av transmissionsdrivningen 18 via en regulatorväxel 21, via vilken enturaxelns varvtal ställs in i beroende av den aktuella arklängden.From a sheet pile 3, sheets 4 are fed via a conveyor belt 5, which belongs to a feeding device generally designated 6, from where they are fed to the caching machine 7 itself in which the sheets are cached on a supporting web 8. From the sheet pile 3 the sheets 4 are partially covered. The front sheet 4 "is directed towards abutment against a front mark 9. After the trailing edge of the outgoing sheet 4 '(Fig. 3) has passed acceleration roller 10, synchronizing rollers 11 are lowered onto the stationary acceleration roller 10 and thereby clamp the sheet 4" between sig. A rotational sensor 13 (Fig. 2) driven by the entraaxel 12 of the sheet pile 3 gives a starting impulse for the acceleration of the sheet 4 "which abuts the front mark 9.0, in which case it is simultaneously folded down. The acceleration and at the same time the lowering of the front mark 9 is thus triggered at a precisely determined degree of the entrail axis 12. During the acceleration of the sheet 4 ", the sheet 4 'previously taken by a sheet transport roller 14 with back pressure roller 15 travels the distance s at a constant machine speed. Below this, the sheet 4 "is accelerated from zero to full machine speed and the distance s / 2 is transported so that, at the moment when the machine speed has been reached, its leading edge will lie exactly against the trailing edge of the previous sheet 4 '. the drive motor 16 of the roller 10 takes place electronically in a manner known per se via a rotary sensor 17 in dependence on the sheet transport roller 14 driven at machine speed via the transmission drive 18 of the casing machine 7 via a guide means 20, a rotation sensor 19 also feeding the machine speed of the sheet transport roller 14 into the guide means 20 The single shaft is also driven by the transmission drive 18 via a regulator gear 21, via which the speed of the single shaft is set depending on the actual sheet length.
Efter det accelerationsvalsen uppnått maskinhastigheten, vrider den sig med konstant hastighet tills arket tagits om hand av ark- transportvalsen 14.After the acceleration roller reaches the machine speed, it rotates at a constant speed until the sheet is taken care of by the sheet transport roller 14.
Vid en kosntant sträcka-s ändrar sig sålunda accelerationen endast i beroende av maskinhastigheten. Formatlängden har inget direkt inflytande på accelerationen.Thus, at a constant distance, the acceleration changes only depending on the machine speed. The format length has no direct influence on the acceleration.
