Abstract

The invention relates to a device for pretensioning film on a binder of the agricultural or industrial type. It consists of a roller (1) guided by two sliding rings (5) and (6) on guides (2) and (3). Pushed to the left by the user when the film is fitted before undertaking binding, the roller (1) around which the film is passed is equipped with tension springs (11) and (12) which become stretched during this operation. During the tilting the film is stretched out over a great length. When it returns to horizontal, the roller (1) slides to the right, thanks to the effect of the springs (11) and (12), thus allowing the film to be pretensioned before the next bale is bound. The device according to the invention is particularly intended for tensioning the film on a machine for binding bales of straw, fodder, ensilage and all agricultural products.

Description

SYSTEME DE PRE-TENSION DE FILM POUR MACHINE A ENRUBANNER
LES BALLES D'ENSILAGE, DE PAILLE, DE FOURRAGE.
FILM PRE-TENSION SYSTEM FOR A WRAPPING MACHINE
BALLS OF SILAGE, STRAW, FORAGE.

La présente invention concerne un système permettant la pré-tension de film sur enrubanneuse agricole ou industrielle munie ou non d'un système d'accrochage automatique de film et d'un dispositif d'étirage de film. The present invention relates to a system for pre-tensioning film on an agricultural or industrial wrapper, whether or not equipped with an automatic film attachment system and a film stretching device.

Actuellement, lors du basculement de la tourelle d'une enrubanneuse, le film qui est accroché sur celle-ci est tiré, puis après le retour à l'horizontal de la tourelle, le film est détendu. Cet état de fait rend difficile sinon impossible l'enrubannage.  Currently, during the tilting of the turret of a wrapper, the film which is hung on it is pulled, then after the return to the horizontal of the turret, the film is expanded. This fact makes wrapping difficult if not impossible.

Le dispositif selon l'invention permet de remédier à cet inconvénient. The device according to the invention overcomes this drawback.

I1 comporte en effet un rouleau vertical, monté sur un châssis, coulissant sur deux guides cylindriques (ou d'autre forme) reliés à deux points haut et bas rendus fixes par un ressort de traction haut et bas. Le film est passé autour du rouleau avant d'être pincé sur la tourelle d'enrubannage. Au départ de l'enrubannage, le rouleau est alors coulissé à gauche, de façon à être contre le dispositif d'étirage à cet instant, et le reste pendant toute l'opération d'enrubannage, jusqu'au moment du basculement. Les ressorts sont étirés. I1 in fact comprises a vertical roller, mounted on a chassis, sliding on two cylindrical guides (or of other shape) connected to two high and low points made fixed by a high and low tension spring. The film is passed around the roller before being pinched on the wrapping turret. At the start of the wrapping, the roller is then slid to the left, so as to be against the stretching device at this instant, and the rest during the entire wrapping operation, until the moment of tilting. The springs are stretched.

Lors du basculement, les ressorts se détendent, permettant ainsi au film qui se déroule lors du basculement de la tourelle porte-balle de rester tendu à ce moment. Le rouleau, monté sur bagues coulissantes revient vers la balle, venant à peu près à mi-course de la distance entre l'avant et l'arrière de la course des guides du rouleau faisant office de tendeur de film pendant toutes les opérations d'enrubannage, basculement et retour de la tourelle. During the tilting, the springs relax, thus allowing the film which takes place during the tilting of the bullet turret to remain taut at this moment. The roller, mounted on sliding rings, returns towards the ball, coming about halfway between the distance between the front and the rear of the travel of the roller guides acting as film tensioner during all the operations of wrapping, tilting and return of the turret.

La tourelle est à ce moment là en position totalement verticale. Dès ce moment, le dispositif d'accrochage et de coupe de film effectue son travail pour permettre à la balle d'être séparée du film qui doit rester en place, près pour enrubanner une ou deux autres balles. Ensuite, la balle est décrochée et stockée verticalement par avancement de l'enrubanneuse. La tourelle se trouve vidée et peut-être ramenée à l'horizontale. Dès ce moment, l'opérateur fait se rabattre la tourelle. Après le basculement, pour que le film ne se prenne pas dans cette tourelle et soit prêt à être utilisé, le dispositif continue son action. Le rouleau cette fois-ci est totalement mis en arrière du dispositif, les ressorts de traction sont pratiquement détendus tout en le restant suffisamment pour tenir le film sous tension. Les supports des rouleaux sont en appuis sur les ressorts de compression. The turret is at this time in a completely vertical position. From this moment, the film hooking and cutting device does its work to allow the bale to be separated from the film which must remain in place, ready to wrap one or two other bales. Then, the bale is unhooked and stored vertically by advancing the wrapper. The turret is emptied and perhaps brought back to the horizontal. From this moment, the operator folds down the turret. After the tilting, so that the film does not get caught in this turret and is ready to be used, the device continues its action. The roller this time is completely put behind the device, the tension springs are almost relaxed while remaining sufficient to keep the film under tension. The roller supports are supported on the compression springs.

L'axe du rouleau est équipé sur sa poulie supérieure d'un galet empêchant la montéedu film, chaque coulisse vient en butée sur un ressort de compression. Chaque guide cylindrique est muni à chaque extrémité de tiges de pré-tension des ressorts de traction.  The axis of the roller is equipped on its upper pulley with a roller preventing the film from rising, each slide comes into abutment on a compression spring. Each cylindrical guide is provided at each end with pre-tension rods for the tension springs.

L'ensemble du système qui est orientable est maintenu en position grâce à une broche et est monté sur le châssis de l'enrubanneuse. Les dessins annexés illustrent l'invention
La figure 1 représente le dispositif seul avec le rouleau en position repos.
The entire system, which is adjustable, is held in position by a spindle and is mounted on the chassis of the bale wrapper. The accompanying drawings illustrate the invention
Figure 1 shows the device alone with the roller in the rest position.

La figure 2 représente le dispositif avant le basculement de la balle (24). FIG. 2 shows the device before the ball (24) is tilted.

La figure 3 représente une vue d'ensemble de l'enrubanneuse et du système. Figure 3 shows an overview of the wrapper and the system.

La figure 4 représente le système avec le film tiré lors du basculement, rouleau à demi-course sur la coulisse. FIG. 4 represents the system with the film drawn during the tilting, roller at half stroke on the slide.

La figure 5 représente le système avec le film retendu par le rouleau du dispositif après remise à l'horizontale de la tourelle. FIG. 5 shows the system with the film stretched by the roller of the device after the turret has been brought back to horizontal.

En référence à ces dessins, le dispositif comporte un rouleau (I), autour duquel est passé le film (21) pris dans la pince (25), qui, est monté sur deux bagues coulissantes (5) et (6). Les ressorts de traction (11) et (12) sont accrochés à une extrémité sur les coulisses, à l'autre extrémité ceux-ci sont fixés sur les supports (7) et (8). Deux tiges filetées (10) et (13) permettent la pré-tension des ressorts (11) et (12) afin de pouvoir régler la résistance opposée au déplacement du rouleau (1). Les coulisses (5) et (6) sont guidées en translation sur les guides cylindriques (2) et (3) fixés sur un montant support (17). Ce montant (17) fait office d'axe d'articulation de l'ensemble du système, ses points de pivot (18) et (19) sont solidaires du châssis 22 et du support tendeur de film de l'enruban- neuse. With reference to these drawings, the device comprises a roller (I), around which the film (21) taken in the clamp (25) has passed, which is mounted on two sliding rings (5) and (6). The tension springs (11) and (12) are hooked at one end on the slides, at the other end these are fixed on the supports (7) and (8). Two threaded rods (10) and (13) allow the pre-tensioning of the springs (11) and (12) in order to be able to adjust the resistance opposed to the movement of the roller (1). The slides (5) and (6) are guided in translation on the cylindrical guides (2) and (3) fixed on a support upright (17). This upright (17) acts as an axis of articulation of the entire system, its pivot points (18) and (19) are integral with the frame 22 and the film tensioning support of the bale wrapper.

Une broche (15) permet le maintien de l'ensemble en position de travail, si elle est placée sur le support (16), en position route si elle est placée sur le support (14). Un galet (4) empêche le film (21) de monter et de se dégager du rouleau lors du basculement de la tourelle (23) de l'enrubanneuse. Les ressorts de compression (9) et (20) sont les amortisseurs destinés à réduire le choc du retour en butée des bagues guides coulissantes (5) et (6) lors de la remise à l'horizontale de la tourelle (23) de ltenrubanneuse. L'Ensemble du dispositif (17) est positionnable à différentes hauteurs
Le système est utilisable sur toutes machines agricoles, industrielles ou autres nécessitant le maintien sous-tension d'un film d'une bande, d'un câble, ou tout autre produit souple, étirable ou non, pour éviter sa distension ou sa cessation de maintien en place.
A pin (15) allows the assembly to be kept in the working position, if it is placed on the support (16), in the road position if it is placed on the support (14). A roller (4) prevents the film (21) from going up and out of the roll when the turret (23) of the wrapper is tilted. The compression springs (9) and (20) are the shock absorbers intended to reduce the shock of the return in abutment of the sliding guide rings (5) and (6) when the turret (23) of the wrapper is brought back to horizontal. . The whole device (17) can be positioned at different heights
The system can be used on all agricultural, industrial or other machines requiring the tension of a film, tape, cable, or any other flexible product, stretchable or not, to avoid distension or its cessation of tension. hold in place.
