Abstract

The coil holding device comprises one or more rotary drums (4) supported at one end for rotation about a generally horizontal axis. An end plate (8) adjacent the support (3) incorporates a spiral groove (5) in the surface running in the opposite sense to the direction of rotation. The groove effectively moves towards the end plate (8) during rotation. A coil (A) mounted on the drum is guided by the groove and is maintained in position on the drum.

Description

La présente invention concerne un dispositif de maintien d'une bobine comportant une grande longueur de fil qui permet une alimentation facile et régulière d'une machine d'allongement ou d'étirage. Les dispositifs classiques de maintien de ce genre sont constitués d'un agencement ayant les caractéristiques suivantes : le tambour de montage de la bobine est placé de façon à être horizontal et à tourner librement, et il comporte une plaque circulaire sur son côté extérieur qui a un diametre supérieur à celui du tambour Qui-même, ce qui permet d'éviter le glissement de la bobine pendant l'alimentation en fil.Cependant, selon ce système, chaque fois qu'une nouvelle bobine de matériau, amenée par un engin de levage ou analogue, est montée sur le tambour, la plaque circulaire doit être enlevée et remontée, ce qui crée embarras et frais de main d'oeuvre supplémentaires. The present invention relates to a device for holding a spool comprising a long length of wire which allows easy and regular feeding of an extension or stretching machine. Conventional holding devices of this kind consist of an arrangement having the following characteristics: the reel mounting drum is placed so as to be horizontal and to rotate freely, and it has a circular plate on its outer side which has a diameter larger than that of the drum itself, which avoids slipping of the spool during the wire feeding. However, according to this system, each time that a new reel of material, brought by a machine of lifting or the like, is mounted on the drum, the circular plate must be removed and reassembled, which creates embarrassment and additional labor costs.

La présente invention a par conséquent pour objet d'éviter ce genre d'inconvénients des dispositifs de maintien existants et de prévoir un équipement de maintien de bobine qui évite l'opération incommode du montage de cette bobine. The present invention therefore aims to avoid this kind of drawbacks of existing holding devices and to provide a coil holding equipment which avoids the inconvenient operation of mounting this coil.

La présente invention a également pour objet de prévoir un dispositif qui évite le glissement de la bobine sur le tambour au cours des opérations d'alimentation en fil grâce à une gorge en spirale qui est découpée sur le pourtour du tambour. Another object of the present invention is to provide a device which prevents the coil from sliding on the drum during wire feeding operations by means of a spiral groove which is cut out around the periphery of the drum.

La présente invention a également pour objet de prévoir un dispositif de maintien de bobine qui permette un fonctionnement parfait de la gorge en spirale indiquée ci-dessus, grâce à la forme conique du tambour, la partie étroite du cône étant du côté support. Another object of the present invention is to provide a reel holding device which allows perfect functioning of the spiral groove indicated above, thanks to the conical shape of the drum, the narrow part of the cone being on the support side.

La présente invention a également pour objet de prévoir un dispositif de maintien de bobine, qui soit apte à éviter que le crochet de levage de la bobine ne s'introduise entre la bobine et le tambour, ce qui en rend l'extraction difficile ; dans ce but, des gorges concaves rectilignes sont prévues longitudinalement dans le tambour. The present invention also has for its object to provide a reel holding device, which is able to prevent the reel lifting hook from being introduced between the reel and the drum, which makes its extraction difficult; for this purpose, rectilinear concave grooves are provided longitudinally in the drum.

La présente invention sera bien comprise à la lecture de la description suivante faite en relation avec les dessins ci-joints, dans lesquels
La figure 1 est une vue en perspective du dispositif de maintien de bobine selon la présente invention
La figure 2 est une vue avant du dispositif ; et
La figure 3 est une vue agrandie de la partie B de la figure 2.
The present invention will be clearly understood on reading the following description made in relation to the attached drawings, in which
Figure 1 is a perspective view of the coil holding device according to the present invention
Figure 2 is a front view of the device; and
FIG. 3 is an enlarged view of part B of FIG. 2.

Dans la figure 1, on a représenté le dispositif de maintien de bobine selon la présente invention, qui comporte un tambour rotatif 4 pour monter une bobine A de matériau qui est placée sur un support 3 lui-même monté sur une plaque 2 de banc. Autour de la surface 4 du tambour, une gorge en spirale 5 est gravée, dont le sens est inverse du sens de rotation du tambour, c'est-à-dire que la gorge en spirale 5 se dirige vers le support 3 pendant le mouvement de rotation du tambour. Le tambour 4 a une forme conique, le diamètre du cône étant plus petit à proximité du support 3, et des gorges concaves, rectilignes 4-1 ... sont pratiquées dans le sens longitudinal du tambour.La plaque 2 du banc du dispositif de la figure 1 est entrainée sur des rails 6 et 6 vers l'avantou vers l'arrière par une chaîne 7 qui est commandée par un moteur réversible, de façon à faciliter les opérations de réglage de la bobine de matériau sur l'équipement d'allongement, étc.. La référence 8 représente les plaques circulaires intérieures qui permettent d'éviter la chute de la bobine A de matériau sur le côté du support 3 lorsqu'elle est placée sur le tambour 4. In Figure 1, there is shown the reel holding device according to the present invention, which comprises a rotary drum 4 for mounting a reel A of material which is placed on a support 3 itself mounted on a plate 2 of the bench. Around the surface 4 of the drum, a spiral groove 5 is engraved, the direction of which is opposite to the direction of rotation of the drum, i.e. the spiral groove 5 goes towards the support 3 during the movement drum rotation. The drum 4 has a conical shape, the diameter of the cone being smaller near the support 3, and concave, rectilinear grooves 4-1 ... are formed in the longitudinal direction of the drum. The plate 2 of the device bench Figure 1 is driven on rails 6 and 6 forwards or backwards by a chain 7 which is controlled by a reversible motor, so as to facilitate the operations of adjusting the coil of material on the equipment of extension, etc. Reference 8 represents the internal circular plates which make it possible to avoid the fall of the coil A of material on the side of the support 3 when it is placed on the drum 4.

Lorsque la bobine A est placée sur le tambour 4 et que le fil est tiré par la machine d'allongement (non représentée), la traction exercée provoque la rotation du tambour 4 et le fil de la bobine tombe dans la gorge en spirale 5. When the spool A is placed on the drum 4 and the thread is pulled by the extension machine (not shown), the traction exerted causes the rotation of the drum 4 and the thread of the spool falls into the spiral groove 5.

Par suite de la rotation du tambour, la gorge 5 essaie de se rapprocher du support 3 et bien que le fil de la bobine essaie de sortie alors que la vitesse de rotation est accélérée, il est maintenu dans la gorge et une alimentation régulière et parfaite se produit constamment sans qu'il y ait chute vers l'extérieur. As a result of the rotation of the drum, the groove 5 tries to approach the support 3 and although the spool thread tries to exit while the speed of rotation is accelerated, it is maintained in the groove and a regular and perfect feeding occurs constantly without falling outward.

Comme cela a été expliqué précédemment, grâce au dispositif de maintien de bobine selon la présente invention, ou la gorge en spirale pratiquée dans l'extérieur du tambour de montage de bobine a un sens inverse au sens de rotation du tambour de sorte qu'elle se déplace vers le support pendant la rotation du tambour au moment de l'alimentation en fil, le fil est dirigé dans la direction interne c'est-à-dire vers le support, par la gorge en spirale alors que le tambour est animé d'un mouvement de rotation. Par con séquent, la fixation de la plaque circulaire extérieure pour éviter que le fil ne tombe comme dans les types de dispositifs classiques, n'est plus nécessaire et rend extrêmement facile l'opération de montage de la bobine sur le tambour. As explained above, thanks to the spool holding device according to the present invention, or the spiral groove made in the exterior of the spool mounting drum has a direction opposite to the direction of rotation of the drum so that it moves towards the support during the rotation of the drum at the time of the wire feeding, the wire is directed in the internal direction i.e. to the support, by the spiral groove while the drum is animated by 'a rotational movement. Consequently, fixing the outer circular plate to prevent the wire from falling as in conventional types of devices is no longer necessary and makes it extremely easy to mount the coil on the drum.

De plus, comme cela est représenté dans l'exemple, le tambour ayant une forme conique vers l'intérieur, c'est-à-dire vers le support, l'effet qui permet d'éviter la chute de la bobine sera renforcé, et les gorges droites longitudinales de forme concave du tambour faciliteront l'insertion de l'extrémité ouverte du crochet de levage pour monter la bobine sur le tambour ; après montage, le crochet pourra être facilement libéré. In addition, as shown in the example, the drum having a conical shape towards the inside, that is to say towards the support, the effect which makes it possible to avoid the fall of the coil will be reinforced, and the longitudinal concave straight grooves of the drum will facilitate insertion of the open end of the lifting hook to mount the spool on the drum; after assembly, the hook can be easily released.

S'agissant du fonctionnement, une paire de tambours 4, 4 est placée sur le support 3 de façon à pouvoir pivoter horizontalement, comme cela est représenté dans l'exemple. Cet agencement est ainsi conçu que pendant l'utilisation d'une bobine sur un tambour, une autre bobine peut être montée sur l'autre tambour 4, et lorsque le matériau de la bobine en service est totalement utilisé, les tambours 4, 4 pivotent horizontalement de 1800 de façon à démarrer une nouvelle opération. With regard to operation, a pair of drums 4, 4 is placed on the support 3 so as to be able to pivot horizontally, as shown in the example. This arrangement is thus designed that during the use of a reel on a drum, another reel can be mounted on the other drum 4, and when the material of the reel in use is fully used, the drums 4, 4 pivot horizontally from 1800 so as to start a new operation.

La présente invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits, elle est au contraire susceptible de variantes et de modifications qui apparaîtront à l'homme de l'art. The present invention is not limited to the embodiments which have just been described, it is on the contrary liable to variants and modifications which will appear to those skilled in the art.
