Definitions

  • the invention relates to a device for connecting the end of an outgoing material web to the beginning of the web of a new winding roll when unwinding material webs, in particular paper or cardboard webs, from a winding roll.
  • splicing devices which connect the end of the outgoing material web with the start of the web of a new winding roll.
  • unwinding heavy paper rolls that are wound on continuous metal axes (reels) and can weigh over 50 t with a web width of 8 m and more the unwinding device and the subsequent processing machine are usually shut down for splicing.
  • the holding device for the running web is pivotally mounted in order to press it against an inserted full winding roll, at the beginning of which a tape is attached. A connection is thus established in which the end of the outgoing web overlaps with the beginning of the new winding roll at the splicing point.
  • the invention has for its object to improve a generic device so that an overlap-free connection of the two webs can be made.
  • connection point does not have twice the web thickness and there is no step-like shoulder (joint) at the splice point.
  • An impact at the splice point can lead to malfunctions in subsequent processing machines.
  • a second carriage is movably mounted transversely across the working width in the space between the two holding elements.
  • This car carries a second tape applicator.
  • the second carriage can be coupled to the first carriage connected to a travel drive; for example by means of a movable bolt. It is thus dragged along by the first car when the web is cut and when the adhesive tapes are applied.
  • Claims 8 and 9 claim the preferred embodiment of the invention, in which the carriage consists of two parts which are rigidly connected to one another via a bridge. A separating knife is arranged on each side of the bridge.
  • This embodiment has the advantage over the embodiment with two carriages that it can be cut in both directions of movement of the carriage. Thus, the car does not need to be moved back to its starting position after cutting the running web in order to cut through the new beginning of the web before gluing.
  • the device according to claims 8 and 9 has the further advantage that no additional storage for a second carriage in the holding device is required.
  • the two carriage parts with the elements attached to them for cutting and applying adhesive tape are exactly aligned with one another. An exact alignment of the elements on both carriages or both carriage parts is necessary so that the webs can be cut without problems and exactly at the highest possible working speed and the adhesive tapes can be applied.

Outside the area of the bridge 48, the two parts 46, 47 are separated from one another by a slot 49, which is located in the swiveled-in working position of the web separating and adhesive tape application device 12 in the area of the web level 4.
  • the two separating knives 16, 45 designed as circular knives are mounted so as to be movable directly next to the bridge 48 on the part 46 in the direction of the part 47 by means of a piston-cylinder unit 24. Each of the two circular knives 16, 45 can thus be moved for cutting against a counter roller 25 attached to part 47. To apply the adhesive tapes 18 the circular knives 16, 45 are moved back into an inactive position at a distance from the counter rollers 25.
  • Each adhesive tape applicator 17, 19 contains a supply roll 26, from which the adhesive tape 18 is pulled off and guided by guide rollers 27, 28 to the plane of the web.
  • Pinch rollers 29, 30, which are arranged at a distance from one another, serve to press the respective adhesive tape 18 against the web 4.
  • a tear-off blade 31 for cutting the respective adhesive tape 18 is mounted between the two pinch rollers 29, 30.
  • Both front pinch rollers 29 of a carriage part 46, 47 are mounted such that they can be pivoted away from one another by means of an associated piston-cylinder unit 32.
  • the carriage 14 is mounted in the swivel beam 13 such that when it swivels against the holding elements 7, 18, the carriage part 47 moves into the space between the two holding elements 7, 8.
  • the carriage part 46 In the swiveled-in position, the carriage part 46 is on one side of the web, the part 47 of the car is on the other side of the web, as shown in FIG.
  • the cutting edges of the two knives 16, 45 are moved through the plane of the web when pressed against the respectively assigned counter roller 25, therefore the web 4 is severed by the respectively activated circular knife 16, 45 when the slide moves across the web width.
  • the two knives 16, 45 arranged on both sides of the fixed bridge 48 thus enable the web 4 to be moved in both possible directions of movement of the slide 14 cut through.
  • the respective circular knife 16, 45 in the direction of movement is activated so that the subsequent bridge 48 can move through the cut.
  • the unwinding process is first braked.
  • the stationary web 4 is clamped to the guide roller 10 by the clamping device 40, and the two holding elements 7, 8 are activated by switching on the suction air.
  • the beam 13 then pivots against the holding device 6, the carriage 14 being located on one side next to the track 4.
  • the carriage 14 is then moved across the width of the web with the activated cutting knife 45 and the web 4 is cut. So that the bridge 48 can move through the cut, the movement of the carriage 14 takes place from the bottom to the top in the illustration according to FIG. When cutting, the two adhesive tape dispensers 17, 19 are inactive, no adhesive tape 18 is applied.
  • the bar 13 is pivoted back into its rest position, and the remaining roll is removed from the unwinding frame 3.
  • the suction tube 38 of the web transport device 37 is pivoted against the full winding roll 1 while the suction air is switched on inside.
  • the beginning of the web is wound onto the suction pipe 38 in a length which corresponds at least to the movement distance of the suction pipe 38 into the lowered position behind the web holding device 6.
  • the beginning of the web of the new winding roll 1 is then transported to behind the web holding device 6 by pivoting the suction tube 38.
  • the web 4 wound on it is unwound except for a few layers.
  • Cutting knife 16 through the cut. It is therefore not necessary to move the carriage 14 back to the original web side before the second cutting process.
  • the new web start of the new winding roll 1 thus created is held by the upper holding element 7, the end of the running web by the lower holding element 8.
  • the two web ends are located directly next to each other without overlap in the web level.
  • the bar 13 pivots again against the holding element 6, the two adhesive tape applicators 17, 19 being activated.
  • the pinch rollers 28, 29 of the two carriage parts 46, 47 are moved against each other.
  • the carriage 14 then travels across the working width (from bottom to top in FIG. 18), an adhesive tape 18 being applied to each side of the web.
  • the separating knives 16, 45 are deactivated, that is to say in a retracted position.
  • the bridge 48 moves through the space between the two web ends before the adhesive tapes 18 are applied connecting the web ends. No empty travel of the carriage 14 is required to apply the adhesive tapes 18 either.

Abstract

Les systèmes connus qui permettent de relier l'extrémité d'une bande (42) de matière finissante avec le début (43) d'un nouveau rouleau (1) lors du déroulement de bandes (4) de matière, en particulier de bandes de papier ou de carton, possèdent un dispositif (16) destiné à sectionner la bande (4) et un dispositif de retenue (6) destiné à retenir l'extrémité de la bande finissante (42). Selon la présente invention, le dispositif de retenue (6) est disposé à demeure adjacent à une face de la bande (4) de matière finissante et possède deux éléments (7, 8) de retenue qui sont placés à un certain écart l'un de l'autre dans le sens de déplacement de la bande. Sur l'autre face de la bande, un dispositif (12) de coupe de bande et d'application de bande adhésive, qui est monté mobile par rapport au dispositif de retenue (6), comporte au moins un appareil d'application (17) de bande adhésive et au moins un couteau de coupe (16). En cas de mouvement du dispositif (12) de coupe de bande et d'application de bande adhésive vers le dispositif de retenue (6), le couteau de coupe (16) se déplace dans le plan de la bande dans l'espace présent entre les deux éléments (7, 8) de retenue. Le début (43) de bande d'un nouveau rouleau (1) est intercepté sur la périphérie dudit rouleau par un dispositif de transport (37) de bande et déplacé jusque derrière la zone du dispositif de retenue (6). Ledit système permet un raccord bout à bout reliant les deux bandes ensemble sans qu'elles se chevauchent.
