Description

The present invention relates to a device for feeding a machine using wire rings.

The present invention relates more particularly to a device for feeding wire reels in wire rings. Such a feeding device must have a certain number of advantages and in particular be able to comprise a large number of crowns (for example a sufficient loading for a working day), being able moreover, with a view to a possible continuous work, be recharged without disturbing the supply of the reel (s) in crowns and possibly be able to present a certain automation.

• - un bâti dont la partie supérieure, formant berceau, est destinée à recevoir les couronnes de fil dont l'axe est sensiblement horizontal,
• - un chariot se déplaçant à l'intérieur et le long dudit bâti, et comportant lui-même un support à position haute et à position basse, lequel support peut se disposer sous la couronne lorsqu'il est en position basse et peut porter ladite couronne lorsqu'il est en position haute, ledit chariot et ledit support comportant des moyens mécaniques pour maintenir ledit support en position haute, et
• - des moyens assurant le déplacement programmé du chariot dans les deux directions le long dudit bâti.

We know from documents US-A-2 419 699 and US-A-2 156 695 a device for feeding a metal strip dispenser from the crowns of said strips which comprises:

• - a frame whose upper part, forming a cradle, is intended to receive the wire rings whose axis is substantially horizontal,
• - A carriage moving inside and along said frame, and itself comprising a support in the high position and in the low position, which support can be placed under the crown when it is in the low position and can carry said crown when in the high position, said carriage and said support comprising mechanical means for maintaining said support in the high position, and
• - Means ensuring the programmed movement of the carriage in both directions along said frame.

The present invention relates to a device of the type described above in which the reel device comprises a base on which are mounted pivoting about a horizontal axis reels which receive a ring of wire while they are in horizontal position or almost horizontal and which are arranged, after loading, in a substantially vertical position to unwind the wire ring. When a wire ring arranged on a reel is finished, its end can be welded with the end of another ring mounted on the other reel. It is thus possible by alternately recharging the two reels to envisage the implementation of an almost continuous reeling of the wire rings.

The invention will be better understood by referring to Figures 1 to 3, said figures illustrating a non-limiting embodiment of the invention. In the example thus illustrated, certain preferential characteristics of the invention will also be mentioned.

• - en 1 le dévidoir que l'on veut alimenter avec le dispositif selon l'invention; ce dévidoir comporte une embase et deux dévidoirs proprement dits 2 et 3 qui sont montés pivotants autour d'un axe horizontal,
• - en 4 un bâti s'étendant longitudinalement devant le dévidoir (il y a un bâti par dévidoir proprement dit); ce bâti est constitué par un certain nombre de poteaux soutenant un berceau, lequel est constitué de deux parties métalliques planes 5 formant un dièdre sur lequel on dépose, à l'aide d'un pont roulant par exemple, les couronnes de fil 6 (ces couronnes ayant un axe horizontal ou sensiblement horizontal),
• - à la base du bâti, on a ménagé deux rails ou chemins de roulement servant de support au déplacement du chariot 7 sur des galets 8,
• - ledit chariot 7 comporte essentiellement un support 9 pouvant prendre une position haute et une position basse. Ce support 9 est représenté en 10 en position basse et en 11 (traits interrompus en position haute). Ce support est constitué d'un bâti supporté par des galets 12 qui assurent le déplacement dudit support de la position haute vers la position basse et vice-versa par roulement sur deux rails inclinés 13, ce bâti comporte deux plaques métalliques formant un dièdre 14 sur lequel les couronnes de fils reposeront. Ledit dièdre est supporté par deux barres 15 parallèles suffisamment longues pour recevoir, éventuellement, d'autres dièdres supports par exemple s'il convient de manipuler des couronnes plus longues que celles actuellement utilisées.

In the figures according to the invention, there is shown:

• - In 1 the reel that we want to supply with the device according to the invention; this reel has a base and two reels proper 2 and 3 which are pivotally mounted about a horizontal axis,
• - in 4 a frame extending longitudinally in front of the reel (there is a frame per reel itself); this frame is made up of a number of posts supporting a cradle, which is made up of two flat metal parts 5 forming a dihedral on which the crowns of wire 6 are deposited (using an overhead crane for example). crowns having a horizontal or substantially horizontal axis),
• - at the base of the frame, two rails or raceways have been provided which support the movement of the carriage 7 on rollers 8,
• - Said carriage 7 essentially comprises a support 9 which can take a high position and a low position. This support 9 is shown in 10 in the low position and in 11 (broken lines in the high position). This support consists of a frame supported by rollers 12 which move said support from the high position to the low position and vice versa by rolling on two inclined rails 13, this frame comprises two metal plates forming a dihedral 14 on which the crowns of wires will rest. Said dihedral is supported by two parallel bars 15 which are long enough to receive, if necessary, other supporting dihedra, for example if it is necessary to handle crowns longer than those currently used.

• - ledit chariot 7 est tracté dans un sens ou l'autre par un moteur 18, ce moteur (par exemple électrique) est réversible et agit par exemple à l'aide du câble 19 passant sur la poulie 20.

The end of the support consists of a stopper 16. Finally, the support includes a mechanical element 17 allowing said support to be held in the high position by snapping said mechanical element onto a corresponding element carried by the carriage,

• - Said carriage 7 is towed in one direction or the other by a motor 18, this motor (for example electric) is reversible and acts for example using the cable 19 passing over the pulley 20.

• - le bâti 4 a été alimenté avec un certain nombre de couronnes de fil 6,
• - un des dévidoirs proprement dit ayant été amené en position horizontale, le chariot (qui se trouve en position de départ au voisinage immédiat de l'extrémité dudit dévidoir) est envoyé pour le chargement de la couronne de fil la plus proche; au moment du démarrage du chariot depuis sa position de départ, un dispositif mécanique adéquat provoque le dé- sencliquetage de l'élément mécanique 17 de sorte que le support 9 descende le long des rails 13 pour se placer en position basse;
• - dans cette position basse, le chariot et son support passent sous la couronne de fil jusqu'à ce que le butoir 16 vienne s'appuyer sur la partie terminale de ladite couronne,
• - la moteur 18 fournit alors un effort suffisant pour, en tirant sur le chariot, provoquer la remontée, le long des rails du support 9 jusqu'à ce que celui-ci arrive à sa position haute (où il porte la couronne de fil) où il se fixe mécaniquement grâce à son dispositif 17. Le moteur 18 ayant enregistré "effort résultant de la montée du support inversera alors son sens de rotation (après quelques secondes de temporisation) et le chariot, portant la couronne, se déplacera vers le dévidoir,
• - lorsque le chariot arrive aux environs du dévidoir (position identique à la position de départ) il stoppe et ne reprend sa marche vers le dévidoir pour la mise en place de la couronne qu'après avoir reçu l'information selon laquelle ledit dévidoir est en place pour recevoir ladite couronne; lorsque la couronne est entièrement enfilée sur le dévidoir, un arrêt de fin de course provoque la remontée du dévidoir et, après temporisation, une inversion de la rotation du moteur et le retour du chariot à la position de départ.

The operation of the device according to the invention can be described as follows:

• the frame 4 was supplied with a certain number of rings of wire 6,
• - one of the reels itself having been brought into a horizontal position, the carriage (which is in the starting position in the immediate vicinity of the end of said reel) is sent for loading the nearest wire ring; when the carriage starts from its starting position, an adequate mechanical device causes the mechanical element 17 to detatch so that the support 9 descends along the rails 13 to place itself in the low position;
• - in this low position, the carriage and its support pass under the wire crown until the stopper 16 comes to bear on the end part of said crown,
• - the motor 18 then provides sufficient effort to, by pulling the carriage, cause the ascent, along the rails of the support 9 until the latter reaches its high position (where it carries the crown of wire) where it is mechanically fixed thanks to its device 17. The motor 18 having recorded "force resulting from the rise of the support will then reverse its direction of rotation (after a few seconds of delay) and the carriage, carrying the crown, will move towards the reel ,
• - when the carriage arrives in the vicinity of the reel (position identical to the starting position) it stops and resumes its march towards the reel for the installation of the crown only after having received the information according to which said reel is in place to receive said crown; when the crown is fully threaded on the reel, an end-of-travel stop causes the reel to rise and, after delay, an inversion of the rotation of the motor and the return of the carriage to the starting position.
