Lifting actuators 4, 6, 7 are mounted on the frame in order to lift the pay-off pack 2 in the process of being emptied and thus to remove it from the pay-out (unreeling) unit 3 into which a new, full pay-off pack 8 is installed for transfer and joining while running. Use for saving space for the feed of a supercalender.

Description

La présente invention concerne une dérouleuse fonctionnant en continu, par exemple pour amener dans une supercalandre une bande de papier provenant dvun fut de bobine, comportant un ensemble de déroulage monté sur une embase, un bloc de déroulage inclus dans 1 ensemble de déroulage et permettant de synchroniser la vitesse d'un rouleau, qui se trouve sur le fut de bobine, avec la vitesse de la bande de papier, et un ensemble formant tte de jonction permettant de faire adhérer la bande de papier provenant du fut de bobine en train de se vider à une bande de ruban adhési+ double face d'un nouveau rouleau. The present invention relates to an unrolling machine operating continuously, for example to bring into a supercalender a paper web from a reel bobbin, comprising a unwinding assembly mounted on a base, a peeler block included in 1 unwinding assembly and allowing synchronize the speed of a roll, which is on the bobbin stock, with the speed of the paper web, and a joining head assembly to adhere the paper web from the bobbin stock being empty to a strip of tape + double-sided tape a new roll.

On utilise des machines de ce type par exemple pçour amener dans une supercalandre une bande de papier provenant d'un fut de bobine, c'est-a-dire par exemple un cylindre sur lequel le papier est initialement enroulé. Machines of this type are used, for example, to bring a strip of paper from a roll bobbin into a supercalender, that is to say for example a roll on which the paper is initially wound.

L'art antérieur est basé sur un ensemble formant dérouleuse fonctionnant en continu, formant un bloc distinct, ce qui rend la dérouleuse couteuse ainsi que plutbt encombrante en particulier dans la direction latérale. The prior art is based on a continuously operating reel unit forming a separate block, which makes the reel expensive and rather cumbersome particularly in the lateral direction.

Le but de l'invention est de surmonter les inconvénients mentionnés ci-dessus et de permettre de réaliser la jonction en marche sur le fut de bobine. The object of the invention is to overcome the drawbacks mentioned above and to make it possible to make the junction in operation on the coil bobbin.

Appareil conforme a l'invention est basé sur des actionneurs de levage qui sont fixes sur le bati de la supercalandre et au moyen desquels on peut lever du bloc de déroulage un f..t de bobine en train de se vider. ConformX- ment à une réalisation préférée de l'invention, la dérouleuse comporte un ensemble de déroulage, deux chariots et des guides qui sont montés sur le bati de la supercalandre et le long desquels les chariots se déplacent, entraînes par des chaines manoeuvrées par vérin hydraulique. Àu moyen des chariots, le fut de bobine en train de se vider est soulevé du bloc de déroulage de l'ensemble de déroulage et on fait rouler dans le bloc de déroulage un nouveau fut de bobine portant un nouveau rouleau.On synchronise la vitesse du nouveau rouleau avec la vitesse de la bande avant de presser la bande contre un ruban adhisif double face qui se trouve à la surface du nouveau rouleau. On détache la bande finissante et on arrête le fat de bobine vide. Apparatus according to the invention is based on lifting actuators which are fixed on the frame of the supercalender and by means of which can be lifted from the unwinding block a coil f..t being emptied. In accordance with a preferred embodiment of the invention, the unwinder comprises a unwinding assembly, two carriages and guides which are mounted on the frame of the supercalender and along which the carriages move, driven by chains actuated by jack hydraulic. By means of the carriages, the spooling bobbin is lifted from the unwinding block of the unwinding assembly and a new roll bobbin bearing a new roll is rolled in the unwinding block. new roll with the speed of the tape before pressing the tape against a double-sided adhesive tape that is on the surface of the new roll. The finishing band is detached and the empty coil fat is stopped.

De façon plus spécifique, l'appareil conforme à l'invention est caractérisé par des actionneurs de levage qui sont montés sur un bati de la supercalandre et sur lesquels un fut de bobine en train de se vider peut strie levé au moins sensiblement verticalement hors du bloc de déroulage, dans lequel se met en place un nouveau fut de bobine pour transfert et jonction en marche. More specifically, the apparatus according to the invention is characterized by lifting actuators which are mounted on a frame of the supercalender and on which a coil is being emptied may streak raised at least substantially vertically out of the unwinding block, in which a new coil is installed for transfer and junction in operation.

Le principal avantage de l'invention est la réduction de l'encombrement. On peut placer la dérouleuse fonctionnant en continu conforme à l'invention dans un espace mBme restreint. Les économies de matériel de construction sont également appréciables en comparaison avec les dispositifs de l'art antérieur car le bâti des actionneurs de levage est constitué par la supercalandre elle-mEme. La construction conforme a l'invention maintient l'ensemble formant teste de jonction toujours orthogonal au fut de bobine indépendamment du diamètre du fut de bobine, en se dispensant par conséquent d'un rouleau de jonction couteux de grandes dimensions pour obtenir une jonction satisfaisante. The main advantage of the invention is the reduction of the bulk. The continuously operating unrolling machine according to the invention can be placed in a small space. The savings of construction equipment are also significant in comparison with the prior art devices because the frame of the lifting actuators is constituted by the supercalender itself. The construction according to the invention maintains the junction test assembly always orthogonal to the coil winding independently of the bobbin diameter, thereby dispensing with a large costly joining roller to obtain a satisfactory junction.

On va examiner ci-dessous 12invention plus en détail au moyen de réalisations prises à titre d'exemple, en référence aux dessins annexés, auxquels
- la figure 1 est une vue latérale schématique partielle d'une dérouleuse fonctionnant en continu conforme a l'invention avant détachement de la bande et jonctionne ment avec un nouveau rouleau
- la figure 2 représente la dérouleuse de la figure 1 en vue avant et partiellement en trait mixte ;
- la figure 3 représente la dérouleuse de la figure 1 en vue de dessus et partiellement en trait mixte
- la figure 4 est unie vue latérale d'une autre réalisation d'une dérouleuse fonctionnant en continu conforme å l'invention.
The invention will now be discussed in more detail by way of example embodiments, with reference to the accompanying drawings, to which
FIG. 1 is a partial schematic side view of a continuous working unwinder according to the invention before detaching the strip and joining a new roll.
- Figure 2 shows the unroller of Figure 1 in front view and partially in dotted lines;
FIG. 3 represents the unrolling machine of FIG. 1 in plan view and partly in dotted line.
- Figure 4 is a side view of another embodiment of a continuous working unroller according to the invention.

La dérouleuse conforme aux figures 1 a fonctionne de la façon suivante : une bande de papier 12 est amenée en provenance d'un rouleau en cours de déroulage qui est sur un fut de bobine 2, à une réenrouleuse (non représentée). en passant par plusieurs rouleaux rigides 16 et plusieurs rouleaux souples 17 d'une supercalandre 5. The unwinding machine according to FIGS. 1a operates as follows: a paper strip 12 is fed from a unwinding roll which is on a roll bobbin 2, to a rewinding machine (not shown). passing through several rigid rollers 16 and several flexible rollers 17 of a supercalender 5.

Tandis que le rouleau en cours de déroulage est en train de se vider sur le filt de bobine 2, porté par des chariots 4 on fait rouler, avec un levier 14, le long des rails 13, un nouveau rouleau monté sur le fat de bobine 8 pour amener dans un bloc de déroulage 3, prévu sur une base il, sous le fut de bobine B, pour l'amener dans un bloc de déroulage 3, prévu sur une base 11, sous le fût de bobine en train de se vider et situé dans l'ensemble de déroulage 1.On synchronise la vitesse du nouveau rouleau monté sur le fut de bobine 8 avec celle de la bande de papier 12, bande de papier 12 que l'on presse contre un ruban adhésif double face qui se trouve sur la surface du nouveau rouleau, au moyen d'une brosse d'un ensemble formant tête de jonction 9. On détache la bande finissante, on arrête le fut de bobine vide 2 et on l'enlève. Au cours du déroulage du nouveau rouleau, son fut de bobine 8 est soulevé vers le haut par des chaines 7 manoeuvrées par un vérin hydraulique le long de guides verticaux 6 montés sur le bati de la supercalandre 5, au moyen de chariots guidés 4, pour laisser de la place pour le prochain nouveau rouleau.While the roller being peeled is being emptied on the spool thread 2, carried by carriages 4 is rolled, with a lever 14, along the rails 13, a new roll mounted on the coil fat 8 to bring in a peeler block 3, provided on a base it, under the coil bobbin B, to bring it in a peeling block 3, provided on a base 11, under the coil drum emptying and located in the unwinding assembly 1.The speed of the new roll mounted on the roll bobbin 8 is synchronized with that of the paper strip 12, paper strip 12 which is pressed against a double-sided adhesive tape which is is located on the surface of the new roll, by means of a brush of a junction head assembly 9. The finishing band is detached, the empty coil end 2 is stopped and removed. During the unwinding of the new roll, its coil 8 was raised upwards by chains 7 operated by a hydraulic cylinder along vertical guides 6 mounted on the frame of the supercalender 5, by means of guided trolleys 4, for leave room for the next new roll.

Le levage du fût de bobine du rouleau qui se dévide peut également entre effectué à l'aide d'un vérin a vis ou, conformément a la figure 4, au moyen de leviers pivotants 10 et de vérins hydrauliques 15 montés sur le bati de supercalandre 5.  The lifting of the unwinding roll bobbin can also be effected by means of a screw jack or, in accordance with FIG. 4, by means of pivoting levers 10 and hydraulic cylinders 15 mounted on the supercalender box. 5.
