Abstract
Description
La présente invention concerne un organe de conditionnement de touret et un touret équipé de cet organe de conditionnement.The present invention relates to a reel conditioning member and a reel equipped with this conditioning member.
On sait que pour le transport d'un câble électrique, téléphonique ou autre, celui-ci est généralement enroulé sur un touret qui est ensuite conditionné pour permettre un transport et un stockage prolongé du câble sans détérioration de celui-ci. Pour le conditionnement du touret on prévoit généralement d'enrouler tout d'abord sur le câble un film de polypropylène chargé de noir de carbone pour le rendre opaque aux rayons ultraviolets, puis un film de matière plastique comportant des bulles d'air emprisonnées pour réaliser une protection contre les chocs, et un lattis de bois formant un emballage de maintien du film polypropylène et du film à bulles. En outre, des lames de bois sont généralement clouées sur le bord des joues du touret pour réaliser une protection extérieure. Le conditionnement d'un touret réalisé dans ces conditions est une opération longue et implique en outre le stockage des quatre matériaux différents destinés à réaliser le conditionnement de sorte que ce conditionnement représente un coût non négligeable qui grève le prix du câble ainsi conditionné.It is known that for the transport of an electric, telephone or other cable, it is generally wound on a reel which is then conditioned to allow transport and prolonged storage of the cable without deterioration thereof. For the packaging of the reel, provision is generally made to first wind on the cable a polypropylene film loaded with carbon black to make it opaque to ultraviolet rays, then a plastic film comprising air bubbles trapped to produce impact protection, and a wooden lath forming a packaging for holding the polypropylene film and the bubble film. In addition, wooden blades are generally nailed to the edge of the reel's cheeks to provide external protection. The packaging of a reel produced under these conditions is a long operation and furthermore involves the storage of the four different materials intended for packaging so that this packaging represents a non-negligible cost which increases the price of the cable thus conditioned.
On connaît également du document GB-A-2.268.468 un touret comportant un organe de conditionnement formé d'une bande en matière thermoplastique ayant une face comportant des parties en surépaisseur donnant à cette face une structure crénelée, et une face sensiblement lisse. D'après ce document, les parties en surépaisseur ont de préférence une largeur égale à la distance entre les faces internes des joues du touret. Lors de la mise en place de l'organe de conditionnement la face crénelée est tournée vers l'intérieur du touret, les parties en surépaisseur étant insérées entre les joues. En outre il est prévu des moyens pour relier les extrémités de la bande l'une à l'autre lors de la mise en place de l'organe de conditionnement. Compte tenu de cette structure l'organe de conditionnement doit être strictement adapté tant en longueur qu'en largeur au touret à conditionner et il n'est donc pas possible d'utiliser un même organe de conditionnement pour des tourets présentant des dimensions variées. En outre la fixation de l'organe de conditionnement en reliant ses extrémités ne permet pas d'obtenir une bonne étanchéité avec le bord des joues.Document GB-A-2,268,468 also discloses a reel comprising a conditioning member formed from a strip of thermoplastic material having a face having excess thickness portions giving this face a crenellated structure, and a substantially smooth face. According to this document, the excess parts preferably have a width equal to the distance between the internal faces of the cheeks of the drum. When the packaging member is put in place, the crenellated face is turned towards the inside of the reel, the excess parts being inserted between the cheeks. In addition, means are provided for connecting the ends of the strip to one the other during the establishment of the conditioning member. Given this structure, the packaging member must be strictly adapted both in length and in width to the drum to be packaged and it is therefore not possible to use the same packaging member for drums having various dimensions. Furthermore, the fixing of the packaging member by connecting its ends does not make it possible to obtain a good seal with the edge of the cheeks.
Selon l'invention on propose un touret comportant des joues circulaires disposées de part et d'autre d'un tambour circulaire et ayant un bord recouvert par un organe de conditionnement formé d'une bande de matière thermoplastique ayant une face crénelée et une face sensiblement lisse, l'organe de conditionnement étant disposé avec la face sensiblement lisse en appui sur le bord des joues et fixée sur le bord des joues.According to the invention there is provided a reel comprising circular cheeks disposed on either side of a circular drum and having an edge covered by a conditioning member formed of a strip of thermoplastic material having a crenellated face and a substantially face smooth, the conditioning member being disposed with the substantially smooth face in abutment on the edge of the cheeks and fixed on the edge of the cheeks.
Ainsi la face sensiblement lisse de l'organe de conditionnement réalise avec le bord des joues du touret une étanchéité suffisante de sorte que l'utilisation de ce seul organe de conditionnement permet d'obtenir les mêmes effets qu'avec les différents organes de conditionnement antérieurs. L'invention présente en outre l'avantage de permettre une adaptation à volonté à des tourets ayant des dimensions variées en retaillant la bande de conditionnement avant ou après sa mise en place.Thus, the substantially smooth face of the packaging member achieves sufficient sealing with the edge of the cheeks of the drum so that the use of this single packaging member makes it possible to obtain the same effects as with the various prior packaging members. . The invention also has the advantage of allowing adaptation at will to drums having various dimensions by cutting the packaging strip before or after its installation.
Par ailleurs, le conditionnement du touret peut être réalisé très aisément en disposant l'organe de conditionnement à plat sur le sol puis en faisant rouler le touret sur l'organe de conditionnement et en clouant ou en agrafant l'organe de conditionnement au fur et à mesure de la rotation du touret. La longueur de l'organe de conditionnement peut être ajustée en fonction du diamètre du touret. Pour faciliter la mise en oeuvre, plusieurs organes de conditionnement de faible longueur peuvent être utilisés pour conditionner un touret de grand diamètre.Furthermore, the packaging of the drum can be carried out very easily by placing the packaging member flat on the ground then by rolling the drum on the packaging member and by nailing or stapling the packaging member as and as the reel rotates. The length of the packaging member can be adjusted according to the diameter of the drum. To facilitate the implementation, several short packaging members can be used to condition a large diameter drum.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention, en relation avec les figures parmi lesquelles:
- la figure 1 est une vue en perspective schématique d'un touret et d'un tronçon d'organe de conditionnement selon l'invention disposé en regard du touret,
- la figure 2 est une vue en coupe partielle de l'organe de conditionnement selon la ligne II-II de la figure 1.
- FIG. 1 is a schematic perspective view of a reel and of a section of packaging member according to the invention placed facing the reel,
- FIG. 2 is a view in partial section of the packaging member according to line II-II of FIG. 1.
En référence aux figures 1 et 2, l'organe de conditionnement de touret selon l'invention est formé d'une bande épaisse 1 de matière thermoplastique comportant des rainures 2 s'étendant transversalement à une direction longitudinale de la bande sur l'une des faces de celle-ci et réalisant une face crénelée tandis que l'autre face est sensiblement lisse.With reference to FIGS. 1 and 2, the reel conditioning member according to the invention is formed from a
Pour une utilisation de l'organe de conditionnement selon l'invention sur des tourets destinés au transport des câbles électriques, il a été expérimenté que d'excellents résultats étaient obtenus avec une bande de matériau thermoplastique d'1 cm d'épaisseur, comportant des rainures d'une largeur de 2 cm et d'une profondeur de 6 mm espacées les unes des autres d'une distance de 8 cm. On obtient ainsi une bande présentant une résistance mécanique satisfaisante et suffisamment flexible pour être enroulée sur un touret. Selon la flexibilité souhaitée les rainures peuvent être plus ou moins espacées et être séparées par des surépaisseurs de dimensions appropriées pour obtenir une résistance adaptée au touret à conditionner.For the use of the packaging member according to the invention on reels intended for the transport of electric cables, it has been tested that excellent results were obtained with a strip of
Afin que l'organe de conditionnement selon l'invention protège le câble contre le rayonnement solaire, en particulier lorsque le touret est stocké en plein air pendant une période de temps prolongée, la matière thermoplastique de préférence inclut une charge la rendant opaque aux rayons ultraviolets.In order for the packaging member according to the invention to protect the cable against solar radiation, in particular when the drum is stored in the open air for an extended period of time, the thermoplastic material preferably includes a filler making it opaque to ultraviolet rays.
L'organe de conditionnement selon l'invention est réalisé de préférence par moulage (injection ou presse) de déchets de matière thermoplastique, par exemple du polyéthylène réticulé et non réticulé chargé de noir de carbone servant à réaliser par extrusion une gaine externe sur les câbles électriques.The packaging member according to the invention is preferably produced by molding (injection or press) of thermoplastic waste, for example crosslinked and non-crosslinked polyethylene loaded with carbon black used to produce an external sheath on the cables. electric.
Ces déchets qui sont généralement impropres à un recyclage pour la réalisation de gaines de câbles sont au contraire tout à fait adaptés à la réalisation de l'organe de conditionnement selon l'invention tant en raison de la facilité de mise en oeuvre pour un moulage qu'en raison de leur propriété de résistance mécanique et de protection contre le rayonnement solaire, la charge rendant la matière plastique opaque aux rayons ultraviolets étant déjà incluse dans les déchets.This waste, which is generally unsuitable for recycling for the production of cable sheaths, is on the contrary entirely suitable for the production of the packaging member according to the invention both because of the ease of implementation for molding and because of their property of mechanical resistance and protection against solar radiation, the filler making the plastic material opaque to ultraviolet rays being already included in the waste.
En référence à la figure 1, on vise selon l'invention à conditionner un touret comportant des joues 4 disposées de part et d'autre d'un tambour 6. La bande 1 a une largeur égale à la distance entre les faces externes des joues 4 d'un touret. Selon l'invention, l'organe de conditionnement est appliqué par sa face lisse sur le bord des joues et les rainures 2 sont tournées vers l'extérieur. La bande 1 est fixée sur le bord 5 des joues par clouage ou agrafage à travers la bande ou par collage sur le bord 5 des joues.With reference to FIG. 1, the aim is according to the invention to condition a
On remarquera que l'organe de conditionnement selon l'invention peut être non seulement mis en place aisément mais également retiré très aisément par un arrachage des clous ou des agrafes. Il est donc généralement possible de récupérer l'organe de conditionnement en vue d'une réutilisation. Lorsque celui-ci est détérioré, il est encore possible de le recycler pour réaliser un nouvel organe de conditionnement. A ce propos on notera que pour obtenir un organe de conditionnement présentant des propriétés mécaniques satisfaisantes tout en assurant une utilisation maximale des déchets de matière thermoplastique résultant de la fabrication de câbles électriques, on réalise de préférence un mélange de 80 % de matière thermoplastique non réticulée et de 20 % de matière thermoplastique réticulée. Ces pourcentages pourront être modifiés selon les caractéristiques désirées du produit final.It will be noted that the packaging member according to the invention can not only be easily put in place but also very easily removed by pulling out nails or staples. It is therefore generally possible to recover the packaging member for reuse. When it has deteriorated, it is still possible to recycle it to produce a new packaging unit. In this regard, it should be noted that for obtain a packaging member having satisfactory mechanical properties while ensuring maximum use of the waste of thermoplastic material resulting from the manufacture of electric cables, a mixture of 80% of non-crosslinked thermoplastic material and 20% of thermoplastic material is preferably produced crosslinked. These percentages can be modified according to the desired characteristics of the final product.
Bien entendu l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to the embodiment described and it is possible to make variant embodiments without departing from the scope of the invention as defined by the claims.
En particulier, bien que l'organe de conditionnement ait été illustré avec des rainures présentant des bords rectilignes on peut les réaliser avec des bords curvilignes ou en créneaux.In particular, although the packaging member has been illustrated with grooves having rectilinear edges, they can be produced with curvilinear or crenelated edges.
