Abstract

This support is of the type comprising a sleeve 2 penetrating into the spindle 3 of the reel, by means of a handle 13 which is screwed longitudinally onto the sleeve and forms a member for adjusting the braking, spindle-centring bushes 7 and 8 interposed between this spindle and bearing surfaces for the support and for the handle, and at least one friction ring 8 interposed between one of the bushes and its bearing surface. According to the invention, it includes spring means 15 which, inserted between the bearing surface of the handle 13 and the bearing surface of the central bush 8 facing it, provide a force for longitudinally clamping the other bush against the friction ring 9, this force depending on the setting of these spring means by screwing the axial handle 13 with respect to the sleeve 2.

Description

"Support de dévidage manuel freiné pour bobine de film étirable"
Pour soti5ari;see une cnrgé sur une palette, il est connu d'envelopper 3'ensemble par un film étirable suivant la technique dite du banderolage. Le film est -mis- en -place--soit par des moyens automatiques, soit manuellement, en saisissant directement'la' bobine ou un support de dévidage portant cette bobine.
"Braked manual unwinding support for stretch film reel"
For soti5ari; see a cnrgé on a pallet, it is known to wrap 3 'together with a stretch film according to the technique known as wrapping. The film is - put in place - either by automatic means, or manually, by directly gripping the reel or a reel support carrying this reel.

De tels '4upports comportent généralement une ossature munie de moyens de préhension et de moyens de maintien de la bobine lui permettant de tourner sur elle-même pour dévider le film, tout en contrôlant cette rotation En -effet, le serrage des spires de film sur la charge dépendant de la - tension de pose du film, il est nécessaire que la rotation soit freinée, afin que la bobine ne se dévide que sous un effort déterminé correspondant à l'effort d'étirage voulu. Cet effort- doit être adapté à la configuration de la-charge et être plus élevé à certains endroits, par exemple, dans les angles. En pratique, la personne assurant le banderolage doit pouvoir régler en permanence la tension d'étirage et donc le freinage du dévidage de la bobine. Such '4upports generally include a frame provided with gripping means and means for holding the reel allowing it to turn on itself to unwind the film, while controlling this rotation. In effect, the tightening of the turns of film on the load depending on the - laying tension of the film, it is necessary that the rotation be braked, so that the reel only unwinds under a determined effort corresponding to the desired stretching effort. This effort must be adapted to the configuration of the load and be higher in certain places, for example, in the corners. In practice, the person ensuring the wrapping must be able to permanently adjust the stretching tension and therefore the braking of the unwinding of the reel.

Le brevet U.S. 4 166 589 décrit un support d'étirage comprenant un manchon pénétrant - dans le fût de la bobine, au moins une poignée se vissant longitudinalement sur le manchon, et constituant organe de réglage du freinage, des douilles de centrage du fût, interposées entre ce fût et des faces d'appui du support et de la poignée, et au moins une bague de friction interposée entre l'une des douilles et sa face d'appui. US Pat. No. 4,166,589 describes a drawing support comprising a sleeve penetrating - into the barrel of the spool, at least one handle which is screwed longitudinally on the sleeve, and constituting the brake adjustment member, the centering sleeves of the barrel, interposed between this barrel and the bearing faces of the support and the handle, and at least one friction ring interposed between one of the sockets and its bearing face.

Ainsi, pendant le banderolage, la rotation manuelle de la poignée vissée sur le manchon modifie l'effort de serrage longitudinal du fût de la bobine sur le support, l'effort de serrage de la garniture de friction et le freinage du dévidage de la bobine. Thus, during the wrapping, the manual rotation of the handle screwed on the sleeve modifies the longitudinal tightening force of the drum of the coil on the support, the force of tightening of the friction lining and the braking of the unwinding of the coil .

En raison de la liaison filetée, poignée-manchon, conduisant à un déplacement axial de la face d'appui de la poignée qui est directement proportionnel au pas du filetage, la course de réglage du serrage de la garniture de friction est très faible et conduit à un réglage grossier du freinage. Due to the threaded connection, handle-sleeve, leading to an axial displacement of the support face of the handle which is directly proportional to the thread pitch, the adjustment stroke of the friction lining tightening is very small and leads coarse brake adjustment.

La présente invention a pour but de fournir un support de dévidage du type précité permettant d'obtenir un réglage fin du freinage grâce à une course de réglage plus grande du serrage de la garniture de friction. The object of the present invention is to provide a reeling support of the aforementioned type making it possible to obtain a fine adjustment of the braking thanks to a greater adjustment stroke for the tightening of the friction lining.

A cet effet, le support, selon l'invention, comporte des moyens à ressorts qui, interposés entre la face d'appui de la poignée et la face d'appui de la douille de centrage lui faisant vis à vis,fournissent un effort de serrage longitudinal de l'autre douille contre la bague de friction dépendant du tarage de ces moyens à ressorts obtenu par vissage de la poignée axiale par rapport au manchon. To this end, the support according to the invention comprises spring means which, interposed between the bearing face of the handle and the bearing face of the centering sleeve facing it, provide a force of longitudinal tightening of the other sleeve against the friction ring depending on the setting of these spring means obtained by screwing the axial handle relative to the sleeve.

Grâce à cet agencement, la course de réglage du freinage est beaucoup plus longue et l'utilisateur peut effectuer un contrôle fin de ce freinage. Thanks to this arrangement, the braking adjustment stroke is much longer and the user can fine-tune this braking.

Dans une forme d'exécution de l'invention, le manchon est solidaire, à l'une de ses extrémités, d'une poignée radiale coudée et d'un disque d'appui pour la bague de friction et comporte à son autre extrémité, un alésage fileté, tandis que la poignée axiale est solidaire d'une tige filetée qui, se vissant dans l'alésage du manchon, est munie, à proximité de cette poignée axiale, d'une bague d'arrêt en translation longitudinale de la douille et des moyens à ressorts. In one embodiment of the invention, the sleeve is integral, at one of its ends, with a bent radial handle and a support disc for the friction ring and comprises at its other end, a threaded bore, while the axial handle is integral with a threaded rod which, being screwed into the bore of the sleeve, is provided, near this axial handle, with a stop ring in longitudinal translation of the sleeve and spring means.

Ainsi, les moyens de réglage font corps avec la poignée axiale et sont imperdables. Thus, the adjustment means are integral with the axial handle and are captive.

D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé dont l'unique figure représente, à titre d'exemple non limitatif, une forme d'exécution de ce support. Other characteristics and advantages will emerge from the description which follows with reference to the appended schematic drawing, the single figure of which represents, by way of nonlimiting example, an embodiment of this support.

Dans ce dessin, 2 désigne le manchon axial du support destiné à pénétrer dans le fût 3 de la bobine 4 de film étirable, 5 désigne une poignée radiale coudée solidaire du manchon 2 et d'un disque d'appui 6, 7 et 8 désignent deux douilles de centrage du fût 3, montées libres en rotation, et 9 désigne une garniture de friction interposée entre la douille 7 et le disque d'appui 6. In this drawing, 2 denotes the axial sleeve of the support intended to penetrate into the barrel 3 of the reel 4 of stretch film, 5 denotes a bent radial handle integral with the sleeve 2 and a support disc 6, 7 and 8 denote two barrel centering sleeves 3, mounted to rotate freely, and 9 designates a friction lining interposed between the sleeve 7 and the support disc 6.

Selon l'invention, le manchon 2 est solidaire, à son extrémité libre, d'une bague 10 filetée intérieurement dans laquelle se visse une tige filetée 12, solidaire d'une poignée axiale 13. La tige filetée 12 est également solidaire d'une bague 14 assurant l'arrêt en translation longitudinale de la douille 8, entre elle-même et la poignée 13. According to the invention, the sleeve 2 is secured at its free end to an internally threaded ring 10 into which a threaded rod 12 is screwed, secured to an axial handle 13. The threaded rod 12 is also secured to a ring 14 ensuring the stop in longitudinal translation of the sleeve 8, between itself and the handle 13.

Suivant la caractéristique essentielle de l'invention, des moyens à ressorts 15, constitués dans cette forme d'exécution par des rondelles coniques et élastiques, dites belleville disposées en opposition, sont interposées entre la douille 8 et la poignée 13. According to the essential characteristic of the invention, spring means 15, constituted in this embodiment by conical and elastic washers, called belleville arranged in opposition, are interposed between the sleeve 8 and the handle 13.

On conçoit aisément que toute rotation communiquée a la poignée 13 provoque le vissage de la tige 12 dans la bague 10 du manchon et, simultanément, une réduction de la distance d entre les faces d'appui de la poignée 13 et la douille 8, et le serrage des rondelles élastiques 15. Ce serrage assure le tarage des rondelles qui communiquent à la douille 8, montée libre en translation et en rotation sur la tige filetée 12, un effort longitudinal dans le sens de la flèche f dépendant de ce tarage.Cet effort se transmet, par le fût 3 de la bobine, à la douille 7 et correspond donc à l'effort de serrage de la garniture de friction entre la douille 7 et le disque d'appui 6.I1 est évident que les rondelles 15 sont choisies de manière que la variation d'efforts en fonction de leur serrage conduisent à une courbe ayant une faible pente de manière à procurer une bonne progressivité du serrage et un contrôle de ce serrage sur plusieurs tours de rotation de la poignée axiale 13. It is easily understood that any rotation communicated to the handle 13 causes the rod 12 to be screwed into the ring 10 of the sleeve and, simultaneously, a reduction in the distance d between the bearing faces of the handle 13 and the sleeve 8, and the tightening of the elastic washers 15. This tightening ensures the calibration of the washers which communicate with the socket 8, mounted freely in translation and in rotation on the threaded rod 12, a longitudinal force in the direction of the arrow f depending on this calibration. force is transmitted, through the barrel 3 of the coil, to the sleeve 7 and therefore corresponds to the force of tightening of the friction lining between the sleeve 7 and the bearing disc 6.I1 it is obvious that the washers 15 are chosen so that the variation of forces as a function of their tightening leads to a curve having a slight slope so as to provide good progressive tightening and control of this tightening over several rotations of rotation of the axial handle 13.

Grâce à cet agencement, le contrôle du freinage de dévidage de la bobine s'effectue sur une plage beaucoup plus longue et permet d'obtenir un contrôle sensitif. Thanks to this arrangement, the braking of the unwinding of the reel is controlled over a much longer range and makes it possible to obtain sensitive control.

I1 est évident que les moyens à ressorts peuvent être remplacés par un ressort hélicoïdal de compression, par une bague élastique interposée entre deux rondelles ou par tout autre moyen équivalent. It is obvious that the spring means can be replaced by a helical compression spring, by an elastic ring interposed between two washers or by any other equivalent means.

Le support est muni d'un piètement 16 permettant de le poser en position verticale. Enfin, et de façon connue, la tige filetée a une longueur déterminée de manière que le dispositif puisse accueillir des bobines ayant des fûts de longueurs différentes.  The support is provided with a base 16 allowing it to be placed in a vertical position. Finally, and in a known manner, the threaded rod has a determined length so that the device can accommodate coils having drums of different lengths.
