Abstract

Un dispositif (10; 10a) pour chauffer une bande en film thermo-déformable (1) comprend des plaques de contact (12) qui sont en contact avec la bande en film (1). Afin de permettre un remplacement simple des plaques de contact (12) soumises à une certaine usure, on propose conformément à l'invention de réaliser le dispositif de chauffage des plaques de contact (12) par exemple à l'aide de radiateurs à infrarouges (15, 15a). Grâce au chauffage indirect des plaques de contact (12), on peut ainsi obtenir une structure simplifiée et un travail de manipulation réduit du dispositif (10; 10a).A device (10; 10a) for heating a thermo-deformable film web (1) comprises contact plates (12) which are in contact with the film web (1). In order to allow a simple replacement of the contact plates (12) subjected to a certain wear, it is proposed in accordance with the invention to produce the device for heating the contact plates (12), for example using infrared heaters ( 15, 15a). Thanks to the indirect heating of the contact plates (12), it is thus possible to obtain a simplified structure and reduced handling work of the device (10; 10a).

Description

i L'invention se rapporte à un dispositif pour chauffer une bande en filmi The invention relates to a device for heating a film strip

thermodéformable dans une installation d'emballage, comportant au moins deux plaques de contact agencées respectivement en vis-à-vis l'une de l'autre, entre lesquelles la bande en film est susceptible de passer, les deux plaques de contact étant mobiles perpendiculairement à la direction de déplacement de la bande en film, et comportant un dispositif de chauffage associé respectivement à l'une des plaques de contact. Des dispositifs connus de ce type comprennent au moins une paire de plaques de contact dont les plaques sont agencées en vis-à-vis l'une de l'autre. La bande en film est transportée entre les plaques de contact, en étant chauffée. Chaque plaque de contact possède un dispositif de chauffage sous forme d'une plaque chauffante fermement reliée à la plaque de contact. On connaît également des modes de réalisation dans lesquels la plaque de contact et la plaque de chauffage sont réalisées en une seule pièce. Dans la plaque de chauffage sont noyés par exemple des fils chauffants électriques. Etant donné que la plaque de contact présente une certaine usure en raison de son contact d'appui avec la bande en film, cette plaque doit être fixée de façon interchangeable sur le dispositif, ce qui est difficile à cause de sa liaison mécanique avec la plaque de chauffage. De plus, la plaque de contact doit également être déplaçable en éloignement de la bande en film, car par exemple lors d'un arrêt de la machine, on doit éviter un chauffage excessif de la bande en film. A cet effet, il faut un dispositif de basculement approprié ou bien un guidage linéaire avec un entraînement d'actionnement correspondant. En raison du couplage de la plaque de contact avec la plaque de chauffage et à cause du poids résultant de l'agencement, ainsi que de l'amenée des lignes de branchement de la plaque de chauffage, une complexité structurelle relativement  heat-deformable in a packaging installation, comprising at least two contact plates arranged respectively opposite one another, between which the film strip is capable of passing, the two contact plates being movable perpendicularly to the direction of movement of the film strip, and comprising a heating device associated respectively with one of the contact plates. Known devices of this type comprise at least one pair of contact plates, the plates of which are arranged opposite one another. The film strip is transported between the contact plates, while being heated. Each contact plate has a heater in the form of a heating plate firmly connected to the contact plate. Embodiments are also known in which the contact plate and the heating plate are made in one piece. In the heating plate are embedded for example electric heating wires. Since the contact plate has some wear due to its bearing contact with the film strip, this plate must be fixed interchangeably on the device, which is difficult because of its mechanical connection with the plate of heating. In addition, the contact plate must also be movable away from the film strip, because for example when stopping the machine, excessive heating of the film strip must be avoided. For this purpose, an appropriate tilting device or a linear guide with a corresponding actuation drive is required. Due to the coupling of the contact plate with the heating plate and due to the weight resulting from the arrangement, as well as the supply of the connection lines of the heating plate, a relatively complex structure

importante s'impose.important is essential.

L'objectif sous-jacent à l'invention est de développer un dispositif de ce type de telle sorte que l'on évite les inconvénients décrits ci- dessus  The objective underlying the invention is to develop a device of this type so that the disadvantages described above are avoided.

de l'état de la technique.state of the art.

Cet objectif est atteint par le fait que le dispositif de chauffage possède des éléments chauffants pour chauffer les plaques de contact au moyen d'un rayonnement thermique, et que le dispositif de chauffage et la plaque de contact sont agencés à distance l'un de l'autre. Un tel dispositif présente l'avantage que la plaque de contact est interchangeable de manière particulièrement simple, car aucun élément de fixation avec le dispositif de chauffage ne doit être détaché et remonté après remplacement de la plaque de contact. De plus, on peut omettre l'application souvent nécessaire d'une pâte thermoconductrice entre la plaque de chauffage et la plaque de contact, ce qui exige un  This object is achieved by the fact that the heating device has heating elements for heating the contact plates by means of thermal radiation, and that the heating device and the contact plate are arranged at a distance from each other. 'other. Such a device has the advantage that the contact plate is interchangeable in a particularly simple manner, since no fastening element with the heating device has to be detached and reassembled after replacement of the contact plate. In addition, the often necessary application of a thermally conductive paste can be omitted between the heating plate and the contact plate, which requires a

travail supplémentaire dans les dispositifs connus.  additional work in known devices.

D'autres avantages et développements avantageux du dispositif conforme à l'invention pour chauffer une bande en film thermodéformable dans une installation d'emballage ressortiront à la  Other advantages and advantageous developments of the device according to the invention for heating a strip of thermo-deformable film in a packaging installation will become apparent from the

To prepare the forming of the cups, pots or the like, the film strip 1 first passes through the device illustrated 10 in a direction which extends perpendicular-

ment au plan du dessin.on the drawing plane.

Le dispositif 10 comprend deux dispositifs de chauffage identiques 11 agencés à symétrie par rapport à la bande en film 1, dont seul le dispositif de chauffage inférieur 1 1 est illustré dans son ensemble dans la figure 1. Le dispositif de chauffage 1 1 possède une plaque de contact 12 en un matériau bon conducteur de la chaleur, de préférence en aluminium, qui est reliée par l'intermédiaire d'éléments d'écartement 13 à une plaque de base 14 agencée parallèlement à la plaque de contact 12. La plaque de contact 12 est fixée de façon interchangeable sur les éléments d'écartement 13 au moyen de fermetures rapides non illustrées. Sur le côté de la plaque de base 14 qui est orienté vers la plaque de contact 12, on a agencé plusieurs radiateurs à infrarouges 15 sur la plaque de base 14. Entre les radiateurs à infrarouges 15 et la plaque de base 14, on a associé en outre à chaque radiateur à infrarouges 15 un élément réflecteur 16 qui reflète en direction de la face inférieure 17 de la plaque de contact 12 le rayonnement thermique  The device 10 comprises two identical heating devices 11 arranged symmetrically with respect to the film strip 1, of which only the lower heating device 1 1 is illustrated as a whole in FIG. 1. The heating device 1 1 has a plate contact 12 made of a good heat conducting material, preferably aluminum, which is connected by means of spacers 13 to a base plate 14 arranged parallel to the contact plate 12. The contact plate 12 is fixed interchangeably on the spacer elements 13 by means of quick fasteners not shown. On the side of the base plate 14 which faces the contact plate 12, several infrared radiators 15 are arranged on the base plate 14. Between the infrared radiators 15 and the base plate 14, there is associated in addition to each infrared radiator 15 a reflective element 16 which reflects towards the underside 17 of the contact plate 12 the thermal radiation

dégagé par le radiateur à infrarouges 15.  released by the infrared radiator 15.

Afin d'obtenir pour la plaque de contact 12 une réception de la chaleur la plus favorable possible, la face inférieure 17 est réalisée de façon rugueuse ou mate, ou bien elle est colorée ou peinte en noir. Par contre, la face supérieure 18 de la plaque de contact 12 orientée vers la bande en film 1 est réalisée avec un recouvrement anti-adhésion. Pour pouvoir chauffer toute la largeur b de la bande en film 1 de façon régulière, la plaque de contact 12 présente en outre une largeur B qui est supérieure à la largeur b_ de la bande en film 1, de sorte que la plaque de contact 12 dépasse au-delà de la bande en film 1 au niveau  In order to obtain the most favorable heat reception possible for the contact plate 12, the underside 17 is produced in a rough or matt manner, or else it is colored or painted black. On the other hand, the upper face 18 of the contact plate 12 oriented towards the film strip 1 is produced with an anti-adhesion covering. In order to be able to heat the entire width b of the film strip 1 regularly, the contact plate 12 also has a width B which is greater than the width b_ of the film strip 1, so that the contact plate 12 protrudes beyond the film strip 1 at the level

de ses zones de bordure latérales.of its side border areas.

Afin de pouvoir écarter la plaque de contact 12, par exemple pendant une pause de production, depuis la bande en film 1 jusque dans la position illustrée dans la figure 1, pour éviter un chauffage fort non désiré de la bande en film 1, la plaque de base 12 est reliée via un levier 19 à un entraînement pneumatique 20. De plus, lors d'un transport intermittent de la bande en film 1, par exemple par un entraînement à pince connu en soi, la plaque de contact 12 est écartée depuis la bande en film 1, afin d'éviter une friction de glissement de la  In order to be able to move aside the contact plate 12, for example during a production break, from the film strip 1 to the position illustrated in FIG. 1, to avoid strong unwanted heating of the film strip 1, the plate base 12 is connected via a lever 19 to a pneumatic drive 20. In addition, during intermittent transport of the film strip 1, for example by a clamp drive known per se, the contact plate 12 is moved away from the film strip 1, in order to avoid sliding friction of the

plaque de contact 12.contact plate 12.

Dans le dispositif modifié 10a illustré dans la figure 2 les radiateurs à infrarouges 15a sont fixés sur une plaque de base fixe 14a. Dans ce cas, les éléments d'écartement 13a sont fixés sur le côté opposé à la plaque de contact 12 sur un châssis supplémentaire 21 qui est accouplé à l'entraînement pneumatique 20. Ainsi, lors du déplacement de la  In the modified device 10a illustrated in FIG. 2 the infrared radiators 15a are fixed on a fixed base plate 14a. In this case, the spacer elements 13a are fixed on the side opposite to the contact plate 12 on an additional chassis 21 which is coupled to the pneumatic drive 20. Thus, during the movement of the

plaque de contact 12, la plaque de base 14a reste à son emplacement.  contact plate 12, the base plate 14a remains in its location.

Grâce à la réduction de la distance par rapport aux radiateurs à infrarouges 15a lorsque la plaque de contact 12 est écartée, la plaque  By reducing the distance from the infrared heaters 15a when the contact plate 12 is moved away, the plate

de contact 12 est chauffée en supplément.  contact 12 is heated additionally.

On notera en supplément que le choix, l'agencement, et la réalisation des radiateurs utilisés pour chauffer les plaques de contact 12 se font bien entendu selon les circonstances données, et qu'ils ne se limitent pas seulement aux radiateurs à infrarouges 15, 1Sa indiqués dans la  It will be noted in addition that the choice, the arrangement, and the realization of the radiators used to heat the contact plates 12 are of course according to the given circumstances, and that they are not limited only to infrared radiators 15, 1Sa indicated in the
