- FIG. 1 there is a laying machine denoted M, for laying sleeves on moving objects, arranged in accordance with the invention.
- the laying machine M has a number of points in common with the laying machine described in the document WO-A-99/59871 above mentioned by the plaintiff. These common elements will therefore be described briefly, but reference may be made to the aforementioned document for further details. details.
- Objects 10, represented here in the form of flasks, run on a conveyor belt 11 in a direction denoted 100, said conveyor belt being driven in motion by associated means not shown here.
- a flat sheath of heat-shrinkable plastics material 13 is fed from a spool 14 rotatably mounted on a frame portion 16, said sheath passing over return rollers 17 and 18 to arrive over an opening shaper sheath 20.
- the sheath opening shaper 20, which is here vertical axis X, comprises an upstream central portion 21 surmounted by a flat portion 22, so as to gradually open the continuous sheath 13 arriving on said shaper.
- the sheath opening shaper 20 further comprises a downstream portion 23, which extends the upstream central portion 21, the separation being made at a groove 24.
- a cutting means 27 with at least one movable blade 28 is carried by a rotating support 29 arranged at the groove 24 to cut the sheath according to a given control instruction, the cut being circularly in a plane P perpendicular to the X axis of the shaper, that is to say in this case essentially horizontal.
- the shaper 20 is of floating type, being held by cooperation between first outer rollers 30, 31 and counter rollers 25, 26 of parallel axes carried by said shaper.
- the continuous sheath 13 thus opens progressively on the upstream portion 21 of the shaper 20, and passes between the roller 30 and the counter rollers 25, and between the roller 31 and the counter rollers 26, respectively, the rollers 30, 31 thus ensuring both a floating support function of the shaper 20 and, by their motorization, a function of advance of the continuous sheath 13 along said shaper.
- Second outer rollers 32, 33 are provided downstream of the cutting means 27 for ejecting the section of cut sheath, noted 15, on an object 10 coming directly above the shaper 20, as a result of the passage of said object in front of a cell 80 .
- an electric motor 41 for driving the pair of rollers 30, 31 of sheath feed, and two electric motors 42, 43 for driving the rollers 32, 33 for ejection of the clipped section of sheath.
- the cutting means 27 is carried by a rotating support 29 which consists of two superimposed rings 55, 57 driven in rotation, and whose rotation speed difference ensures, by means of a particular cam system which will be described next. in more detail, the alternating pivoting of the cutting blade or blades 28 between a retracted position and a cutting position.
- the driving of these two superimposed rings 55, 57 is ensured, by means of belts 56, 58, by two electric motors 48, 49.
- the aforementioned electric motors 41, 42, 43, 48, 49 are connected, by associated lines 51, 52, 53, 54, 54 'respectively, by a common electronic programmer 50 with a virtual shaft.
- the cell 80 which sees each scrolling object 10 is connected by a line 81 to the common electronic programmer 50, in particular to transmit the signal authorizing the control of the motors 42, 43 associated with the ejection of the section of sheath cut on the object 10 coming in line with the shaper 20.
- the general synchronization is ensured by the common electronic virtual shaft programmer 50 which includes at least one electronic control card 55 with multiple commands which is connected to the control lines 51, 52, 53, 54, 54 'above.
- the cutting means 27 'then consists of a plurality (here four) of razor blades 28' arranged to pivot in a common plane which is the cutting plane.
- Each blade 28 ' is mounted on a blade holder 62' provided with an axis 61 'which is journalled on a rotating ring 55', and the blades 28 'rotate in synchronism in a single movement between their retracted position and their cutting position.
- each blade 28 'between its retracted position and its cutting position is ensured by means of a cam system 59' of circumferential type in which a roller 59'.1 associated with the blade holder 62 'of each blade 28 'circulates in a cam track bounded by 360 ° by coaxial tracks 59'.2, 59'.3 of a fixed ring 57'.
- the four blades 28 ' are in the retracted position.
- such an arrangement is incompatible with very high speeds, and the wear of the rollers 59'.1 is fast and difficult to control.
- the invention overcomes this limitation through an arrangement in which the alternating pivoting of the or each blade 28 between its retracted position and its cutting position is provided by means of a cam system. 29 by the difference in rotation of two superimposed rotating rings 55, 57 constituting the support of said blade, one of which (here the upper ring 55) has a straight cam path 60 parallel to the section plane P and oblique direction, in which slides an elongated cam 59.1 which is integral in rotation with the blade holder 62 via an axis 61 which is parallel to the common axis X of the rings 55, 57 and journalled on the other rotary ring 57.
- the support of the cutting means 29 thus consists of two superimposed rotary rings 55, 57 driven in rotation about the X axis (arrow 101), the alternating phase shift between these two rings generating the movement of the blade holders 62 thanks to the cam system 59 connected to the axis 61, which axis is coupled to an associated sliding cam 29.1 passing in a cam path 60 arranged in the upper ring 55.
- This arrangement is better visible in the partial view of the figure 9 , where the other ring 57 has not been shown, the shaded area 61.1 of the axis 61 here symbolizing the other ring 57 by the area where said axis is journalled in said ring.
- the ring 57 is therefore almost identical to the ring 55, but does not have the four straight and oblique cam paths 60.
- FIG 3 there is shown a conventional type cutting system which could equip the laying device of the aforementioned type, with in a), the two blades 28 which are in the retracted position, that is to say that the tip 68 of the end of the blade 65 is at a distance (for example 3 mm) from the sheath wall 13, facing the groove 24 of the shaper 20.
- each blade 28 is in the cutting position.
- the invention proposes a more efficient solution, with here two embodiments given by way of non-limiting example, respectively illustrated in FIGS. Figures 5, 6 , 10 and to Figures 7, 8 , in which the or each blade 28 has a free end 65 which is arranged to pierce the wall of the sheath 13 and cut said wall while exerting thereon a force F directed radially outwardly.
- each blade 28 is such that the wall of the sheath 13 is first pierced, then cut by being pulled radially outwardly during the rotation of the blade support around the blade.
- a first way of ensuring this double function of cutting and drawing the wall cut in a radially outer direction consists in providing that the free end, denoted 65, of the or each cutting blade 28 is shaped as a hooked beak, as illustrated in Figures 5, 6 , and 10 .
- the hooked free end 65 has a concave arc-shaped cutting edge 66 extending to a point 68 of the blade, the other edge 67 (non-cutting) is convex arc-shaped.
- Each blade 28 is mounted on its blade holder 62, being held in an associated slide 63 of said blade holder by means of pins 70 of the blade holder received in an oblong slot 69 of the blade 28.
- Each blade 28 is thus arranged to rotate about an axis X1 parallel to the X axis of the shaper, the reciprocating pivoting of the blade 28 being between a rear position or withdrawal, in which the tip 68 is not in contact with the wall of the sheath 13, and a cutting position, wherein said tip 68 has passed through the wall of the sheath to be cut and has penetrated slightly into the associated groove 24 of the shaper 20.
- an individual quick-release fastening means which here consists of a sliding bar 64 arranged to pass over the blade 28 in order to maintain it, or to release said blade to allow removal.
- this slide bar 64 is shown in the holding position, and it suffices to act manually on a projecting lug 64.1 of said bar to retract it and access the blade 28 for removal.
- the blade 28 is then arranged so that its hooked end 65 intersects the wall of the sheath 13 while maintaining an orientation such that the two aforementioned tangents T and ⁇ , at the point of attack J, are between them ⁇ angle less than 90 °, for example here about 75 °.
- the force F exerted on the sheath wall at the point J is then turned outwardly of the groove 24 of the shaper 20, thus illustrating the effect of traction obtained which avoids pushing the sheath wall into said groove.
- Another way to ensure the dual function of cutting and pulling the wall cut in one direction radially outer is to provide that the free end 65 of the or each blade 28 has a cutting edge 66 which is rectilinear, and whose direction defines the tangent to the cutting edge ⁇ , and with a direction of the blade which is modified (for example by changing the direction of the slide 63 of the blade holder 62) to maintain an angle ⁇ which is less than 90 °, for example 60 ° to 80 °, in contrast to the arrangement of figures 3 and 4 where the cutting edge 66 is rectilinear, but where the angle ⁇ is obtuse.
- the pivoting of the blade 28 is adjusted so that the penetration distance of the free end 65 of said blade in the groove 24 of the shaper 20 is just sufficient to ensure the passage of the wall of the sheath 13.
- This penetration distance which is indicated by a parameter a2, will for example be about 2 to 3 mm, so in this case close to the separation distance a1 in the retracted position of the blade 28 ( figures 5 and 7, a) ).
- the adjustment of this penetration distance must, however, be chosen with care if it is desired to obtain the desired double effect of both piercing and pulling the wall of the sheath in an outer direction. In practice, the penetration distance should not exceed a value of about 3mm, otherwise it becomes very difficult to exercise the desired traction force F.
- a support consisting of two superimposed rotating rings 55, 57, driven in rotation about the X axis by the respective belts 56, 58 which are connected to the output shaft of the aforementioned drive motors 48, 49.
- the two superposed rings 55, 57 are driven in rotation to speeds close to each other, with a slight alternating phase shift which is here driven by the common electronic programmer 50.
- the cam system 59 with its cams 59.1 sliding in their cam path 60, is arranged such that a rotation speed difference (in one direction or another) between the rings 55, 57 imparts a movement to each cam of the cam system 59, and consequently a pivoting of each door lamina 62 around its axis X1.
- a rotation speed difference in one direction or another
- controlling the angular phase shifts between the rings 55, 57 ensures a very precise control of the pivoting of each of the blades 28 between their retracted position and their cutting position.
- the alternating pivoting of the blades 28 is thus perfectly controlled, in speed and in position, by the difference in rotation of the two superimposed rings 55, 57.
- the height of the groove 24, denoted h, as illustrated on the figure 11 will be chosen so that the blade 28 can penetrate without risk of interference in said groove at the highest rates.
- the laying machine allows use at very high speeds, for example 600 rounds per minute, and with sheaths whose constituent film is thin, for example 25 microns, and low density, for example a density less than 1.

Abstract
Description
La présente invention concerne la pose de manchons, en particulier la pose de manchons thermorétractables, sur des objets en défilement, les objets revêtus de leur manchon passant ensuite au niveau d'un four de rétraction.The present invention relates to the laying of sleeves, in particular the installation of heat shrink sleeves, on moving objects, the coated objects of their sleeve then passing at a retraction furnace.
Pour la pose de manchons thermorétractables sur des objets en défilement, on utilise classiquement une technique selon laquelle les manchons sont tronçonnés à partir d'une gaine continue passant sur un conformateur d'ouverture de gaine, qui est maintenu flottant par coopération entre des galets extérieurs et des contre-galets d'axes parallèles portés par le conformateur, lesquels galets extérieurs assurent l'avance de la gaine le long du conformateur, en général vertical, jusqu'à et au-delà d'un moyen de coupe. D'autres galets sont en général prévus en aval du moyen de coupe pour éjecter le tronçon de gaine coupé sur l'objet venant à l'aplomb du conformateur.For the installation of heat-shrink sleeves on moving objects, a technique is conventionally used in which the sleeves are cut from a continuous sheath passing over a sheath-opening shaper, which is kept floating by cooperation between outer rollers. and counter-rollers of parallel axes carried by the shaper, which outer rollers ensure the advance of the sheath along the shaper, generally vertical, to and beyond a cutting means. Other rollers are generally provided downstream of the cutting means for ejecting the section of sheath cut on the object coming directly above the shaper.
Ainsi, dans la plupart des techniques utilisées, on trouve des premiers galets extérieurs destinés à assurer l'avance de la gaine sur le conformateur, et des seconds galets extérieurs servant à éjecter le tronçon de gaine coupé sur l'objet concerné. Tous ces galets extérieurs sont bien entendu motorisés, et leur motorisation a donné lieu à différents types d'agencements.Thus, in most of the techniques used, there are first outer rollers intended to ensure the advance of the sheath on the shaper, and second outer rollers for ejecting the section of sheath cut on the object concerned. All these outer rollers are of course motorized, and their motorization has given rise to different types of arrangements.
Il a ainsi été proposé d'avoir une motorisation complètement indépendante pour les seconds galets et les premiers galets, afin de pouvoir faire tourner les seconds galets beaucoup plus vite que les premiers, ceci pour précipiter la chute verticale du tronçon de gaine coupé sur l'objet concerné. Cette approche est illustrée dans le document
On s'est cependant aperçu que les techniques précitées imposaient des limites en termes de cadencement, car, lorsqu'on arrive aux cadences élevées, on a constaté que des manchons étaient fréquemment mal positionnés sur des objets, et ce a fortiori s'il s'agissait de manchons de hauteur importante.However, we realized that the techniques The above mentioned limitations in terms of timing, because, when arriving at high speeds, it was found that sleeves were often poorly positioned on objects, especially if they were sleeves high height.
Un pas important a été franchi plus récemment avec une technique mettant en oeuvre une commande des moteurs électriques concernés réalisée en synchronisme par un programmateur électronique commun agencé pour déterminer un profil continu de variation des vitesses, afin de piloter l'éjection de chaque tronçon de gaine, ledit programmateur incluant au moins une carte de commande qui coopère avec un codeur adjacent monté en bout d'un arbre entraîné en rotation par un groupe moto-réducteur central. Ceci est illustré dans le document
Il existe cependant une demande croissante de cadencements de plus en plus élevés, atteignant couramment des valeurs de 300 à 600 coups par minute.There is, however, a growing demand for increasingly higher clock speeds, typically ranging from 300 to 600 strokes per minute.
On alors préféré utiliser des machines plus perfectionnées en abandonnant le système d'avancement pas à pas des objets, ainsi que le système de codeur monté en bout d'un arbre entraîné en rotation par un groupe moto-réducteur central (comme décrit dans le document
Parallèlement à cette recherche de cadences très élevées, il existe également une tendance à utiliser des gaines constituées à partir d'un film thermorétractable d'épaisseur de plus en plus faible. A titre indicatif, les techniques classiques utilisaient des films thermorétractables dont l'épaisseur était de l'ordre de 50 µm, alors que maintenant on cherche à utiliser des films de matière plastique thermorétractable de plus faible épaisseur, c'est-à-dire pouvant descendre jusqu'à 25 µm, et aussi de plus faible densité.Parallel to this search for very high rates, there is also a tendency to use sheaths made from a heat shrinkable film of increasingly weaker thickness. As an indication, the conventional techniques used heat-shrinkable films whose thickness was of the order of 50 microns, whereas now it is sought to use heat-shrinkable plastic films of smaller thickness, that is to say up to 25 microns thick. μm, and also of lower density.
La double exigence précitée complique ainsi considérablement l'agencement des dispositifs de pose de manchons, et l'on peut relever un type de problème technique qui se pose de façon de plus en plus aiguë, et qui concerne le processus de coupe de la gaine immobilisée sur le conformateur d'ouverture de gaine.The aforementioned double requirement thus considerably complicates the arrangement of sleeving devices, and there is a type of technical problem which is increasingly acute, and which concerns the cutting process of the immobilized sheath. on the sheath opening shaper.
En effet, le moyen de coupe traditionnellement utilisé met en oeuvre au moins une lame qui tourne autour du conformateur au niveau d'une gorge profonde de celui-ci qui est associée à un ligament réunissant les deux parties constitutives du conformateur, le pivotement alterné de la ou de chaque lame entre sa position de retrait et sa position de coupe étant assuré au moyen d'un système de came de type circonférentiel selon lequel un galet associé à la ou à chaque lame circule dans un chemin de came délimité sur 360° par des pistes coaxiales d'une couronne fixe. Or, on s'est aperçu qu'un tel agencement devenait impraticable aux cadences très élevées, et que l'usure rapide des galets était très difficile à contrôler. On a illustré à titre d'exemple un tel agencement à la
De plus, lors du processus de coupe, le bord de coupe de la lame attaque la paroi de la gaine au niveau de la gorge précitée du conformateur, en exerçant un effort de poussée important afin de traverser la paroi de la gaine. Or on s'est aperçu que cet effort radial a pour effet de repousser les lèvres de coupe dans la gorge précitée, ce qui occasionne un bord de coupe qui n'est pas parfaitement rectiligne mais présente des irrégularités, et génère en outre un risque inhérent aux déformations d'enfoncement subies par la gaine qui ne peuvent que perturber le processus normal d'avance de gaine et d'éjection du tronçon coupé. Cet effet négatif de poussée de la paroi de gaine lors de la coupe devient encore plus aigu lorsque l'on utilise des manchons réalisés à partir d'un film thermorétractable de faible épaisseur et de faible densité.In addition, during the cutting process, the cutting edge of the blade attacks the wall of the sheath at the aforementioned groove of the shaper, exerting a large thrust force to pass through the wall of the sheath. Now it has been found that this radial force has the effect of pushing the cutting lips in the aforementioned groove, which causes a cutting edge which is not perfectly straight but has irregularities, and also generates an inherent risk deformations of depression experienced by the sheath that can only disturb the normal process of sheath advance and ejection of the cut section. This negative thrust effect of the sheath wall during cutting becomes even more acute when sleeves made from a heat-shrinkable film of small thickness and low density are used.
L'état de la technique concernant plus spécifiquement les systèmes de coupe de gaine continue qui équipent les machines de pose de manchons sur des objets en défilement, est également illustré dans les documents mentionnés ci-après.The state of the art relating more specifically to the continuous sheath cutting systems that equip the sleeves laying machines on moving objects, is also illustrated in the documents mentioned below.

Le problème précité est résolu conformément à l'invention grâce à un dispositif de pose de manchons sur des objets en défilement, lesdits manchons étant tronçonnés à partir d'une gaine continue passant sur un conformateur d'ouverture de gaine ayant un axe central, lequel conformateur est maintenu flottant entre des premiers galets extérieurs et des contre-galets d'axes parallèles portés par ledit conformateur, jusqu'à et au-delà d'un moyen de coupe, des seconds galets extérieurs étant prévus en aval du moyen de coupe pour éjecter le tronçon de gaine coupé sur un objet venant à l'aplomb du conformateur par suite du passage dudit objet devant une cellule, le moyen de coupe comportant au moins une lame montée sur un support qui est agencé pour tourner autour du conformateur, la ou chaque lame pouvant pivoter sur ledit support tournant en restant dans un plan essentiellement perpendiculaire à l'axe du conformateur, en regard d'une gorge dudit conformateur, alternativement entre une position de retrait et une position de coupe dans laquelle elle pénètre en partie dans ladite gorge du conformateur, ledit dispositif étant remarquable en ce que le pivotement alterné de la ou de chaque lame entre sa position de retrait et sa position de coupe est assuré au moyen d'un système de came par la différence de rotation de deux couronnes tournantes superposées constituant le support de la ladite lame, dont l'une présente un chemin de came parallèle au plan de coupe et de direction oblique, dans lequel coulisse une came qui est solidaire en rotation d'un porte-lame par l'intermédiaire d'un axe parallèle à l'axe commun des couronnes et tourillonné sur l'autre couronne, et en ce que la ou chaque lame présente une extrémité libre qui est agencée pour percer la paroi de la gaine et couper ladite paroi tout en exerçant sur celle-ci une force (F) dirigée radialement vers l'extérieur.The aforementioned problem is solved according to the invention by means of a device for laying sleeves on moving objects, said sleeves being cut from a continuous sheath passing over a sheath opening shaper having a central axis, which shaper is maintained floating between first outer rollers and counter rollers of parallel axes carried by said shaper, to and beyond a cutting means, second outer rollers being provided downstream of the cutting means for eject the section of sheath cut on an object coming directly above the shaper as a result of the passage of said object in front of a cell, the cutting means comprising at least one blade mounted on a support which is arranged to turn around the shaper, the or each blade being pivotable on said rotating support while remaining in a plane substantially perpendicular to the axis of the shaper, facing a groove of said shaper, alter nally between a withdrawal position and a cutting position in which it partially penetrates into said shaper groove, said device being remarkable in that the alternating pivoting of the or each blade between its retracted position and its cutting position is provided by means of a cam system by the difference of rotation of two superimposed rotating crowns constituting the support of said blade, one of which has a cam path parallel to the oblique cutting plane and direction, in which slides a cam who is integral in rotation with a blade holder via an axis parallel to the common axis of the rings and journalled on the other ring, and in that the or each blade has a free end which is arranged to piercing the wall of the sheath and cutting said wall while exerting thereon a force (F) directed radially outwardly.
A cet effet, il est prévu que la ou chaque lame soit agencée de façon que son extrémité coupe la paroi de la gaine en conservant une orientation telle que la tangente au bord de coupe forme avec la tangente à la paroi de gaine, dans le sens de rotation du support de ladite lame, un angle (α) inférieur à 90°. En particulier, l'angle (α) entre les deux tangentes est choisi voisin de 75°.For this purpose, it is provided that the or each blade is arranged so that its end intersects the wall of the sheath while maintaining an orientation such that the tangent to the cutting edge forms with the tangent to the sheath wall, in the direction rotation of the support of said blade, an angle (α) less than 90 °. In particular, the angle (α) between the two tangents is chosen to be close to 75 °.
Ainsi, les caractéristiques précitées permettent de garantir que la paroi de la gaine est d'abord percée, puis coupée en étant tirée radialement vers l'extérieur, sans risque que les lèvres de coupe soient repoussées en direction de l'axe du conformateur, et ce même aux cadences les plus élevées et avec des parois de gaine très minces.Thus, the abovementioned characteristics make it possible to guarantee that the wall of the sheath is first pierced, then cut off by being pulled radially outwards, without the risk that the cutting lips are pushed towards the axis of the shaper, and this same at the highest rates and with very thin sheath walls.
Selon un mode d'exécution particulier, l'extrémité libre de la ou de chaque lame est conformée en bec crochu. Avantageusement alors, l'extrémité libre en bec crochu de la ou de chaque lame présente un bord de coupe en forme d'arc concave s'étendant jusqu'à une pointe de ladite lame dont l'autre bord est en forme d'arc convexe.According to a particular embodiment, the free end of the or each blade is shaped hook beak. Advantageously then, the hooked free end of the or each blade has a concave arc-shaped cutting edge extending to a tip of said blade whose other edge is convex arc-shaped. .
Selon un autre mode d'exécution particulier, l'extrémité libre de la ou de chaque coupe présente un bord de coupe qui est rectiligne, et dont la direction définit la tangente au bord de coupe.According to another particular embodiment, the free end of the or each section has a cutting edge which is rectilinear and whose direction defines the tangent to the cutting edge.
De préférence encore, la ou chaque lame est fixée sur son porte-lame par un moyen individuel de fixation à démontage rapide. En particulier, le moyen individuel de fixation à démontage rapide comporte une barrette coulissante agencée pour passer sur la lame afin d'en assurer le maintien, ou pour libérer ladite lame afin d'en permettre l'enlèvement.More preferably, the or each blade is fixed on its blade holder by an individual quick-release fastening means. In particular, the individual quick-release fastening means comprises a sliding bar arranged to pass over the blade in order to maintain it, or to release said blade in order to allow removal.
Il est par ailleurs intéressant de prévoir que le support porte une pluralité de lames angulairement réparties et agencées pour pivoter dans un plan commun.It is also advantageous to provide that the support carries a plurality of blades angularly distributed and arranged to pivot in a common plane.
Avantageusement alors, le système de cames est agencé de telle sorte que les lames pivotent en synchronisme selon un même mouvement entre leur position de retrait et leur position de coupe.Advantageously then, the cam system is arranged so that the blades rotate in synchronism in the same movement between their retracted position and their cutting position.
Il est dans ce cas intéressant de prévoir que le pivotement alterné des lames est réglé pour que la distance de pénétration de l'extrémité libre de celle-ci dans la gorge du conformateur soit juste suffisante pour garantir la traversée de la paroi de la gaine, en particulier de 2 à 3 mm environ.In this case it is advantageous to provide that the alternating pivoting of the blades is adjusted so that the distance of penetration of the free end thereof into the groove of the shaper is just sufficient to ensure the passage of the wall of the sheath, in particular about 2 to 3 mm.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lumière de la description qui va suivre et des dessins annexés, concernant un mode de réalisation particulier.Other features and advantages of the invention will emerge more clearly in the light of the following description and the accompanying drawings, relating to a particular embodiment.

Sur la
La machine de pose M comporte un certain nombre de points communs avec la machine de pose décrite dans le document
Des objets 10, représentés ici sous la forme de flacons, défilent sur un tapis de convoyage 11 dans une direction notée 100, ledit tapis de convoyage étant entraîné en défilement par des moyens associés non représentés ici.
Une gaine plate de matière plastique thermorétractable 13 est débitée à partir d'une bobine 14 montée tournante sur une partie de châssis 16, ladite gaine passant sur des rouleaux de renvoi 17 et 18 pour arriver au-dessus d'un conformateur d'ouverture de gaine 20. Le conformateur d'ouverture de gaine 20, qui est ici d'axe vertical X, comporte une partie centrale amont 21 surmontée d'une partie plate 22, de façon à ouvrir progressivement la gaine continue 13 arrivant sur ledit conformateur. Le conformateur d'ouverture de gaine 20 comporte en outre une portion aval 23, qui prolonge la portion centrale amont 21, la séparation se faisant au niveau d'une gorge 24.A flat sheath of heat-
Un moyen de coupe 27 avec au moins une lame mobile 28 est porté par un support tournant 29 agencé au niveau de la gorge 24 pour couper la gaine selon une instruction de commande donnée, la coupe se faisant circulairement selon un plan P perpendiculaire à l'axe X du conformateur, c'est-à-dire en l'espèce essentiellement horizontal.A cutting means 27 with at least one
Le conformateur 20 est de type flottant, en étant maintenu par coopération entre des premiers galets extérieurs 30, 31 et des contre-galets 25, 26 d'axes parallèles portés par ledit conformateur.The
La gaine continue 13 s'ouvre ainsi progressivement sur la partie amont 21 du conformateur 20, et passe entre le galet 30 et les contre-galets 25, et entre le galet 31 et les contre-galets 26, respectivement, les galets 30, 31 assurant ainsi à la fois une fonction de support flottant du conformateur 20 et, par leur motorisation, une fonction d'avance de la gaine continue 13 le long dudit conformateur.The
Des seconds galets extérieurs 32, 33 sont prévus en aval du moyen de coupe 27 pour éjecter le tronçon de gaine coupé, noté 15, sur un objet 10 venant à l'aplomb du conformateur 20, par suite du passage dudit objet devant une cellule 80.Second
On a représenté schématiquement un moteur électrique 41 servant à entraîner la paire de galets 30, 31 d'avance de gaine, et deux moteurs électriques 42, 43 servant à entraîner les galets 32, 33 d'éjection du tronçon de gaine coupé.There is shown schematically an
Le moyen de coupe 27 est porté par un support tournant 29 qui est constitué de deux couronnes superposées 55, 57 entraînées en rotation, et dont la différence de vitesse de rotation assure, par le biais d'un système de cames particulier qui sera décrit ensuite plus en détail, le pivotement alterné de la ou des lames de coupe 28 entre une position de retrait et une position de coupe. L'entraînement de ces deux couronnes superposées 55, 57 est assuré, par l'intermédiaire de courroies 56, 58, par deux moteurs électriques 48, 49.The cutting means 27 is carried by a rotating
Les moteurs électriques précités 41, 42, 43, 48, 49 sont reliés, par des lignes associées respectivement 51, 52, 53, 54, 54', par un programmateur électronique commun 50 à arbre virtuel. La cellule 80 qui voit passer chaque objet en défilement 10, est reliée par une ligne 81 au programmateur électronique commun 50, afin notamment de transmettre le signal autorisant la commande des moteurs 42, 43 associés à l'éjection du tronçon de gaine coupé sur l'objet 10 venant à l'aplomb du conformateur 20. La synchronisation générale est assurée par le programmateur électronique commun à arbre virtuel 50 qui inclut au moins une carte de commande électronique 55 à multiples commandes qui est connectée aux lignes de commande 51, 52, 53, 54, 54' précitées.The aforementioned
On va maintenant décrire plus en détail l'agencement du moyen de coupe 27 servant à couper la paroi de la gaine 13 au niveau de la gorge 24 du conformateur 20, cette passe de coupe intervenant juste après l'arrêt de l'avance de la gaine, et juste avant l'éjection du tronçon de gaine coupé 15.The arrangement of the cutting means 27 for cutting the wall will now be described in more detail. of the
Pour mieux comprendre le mode opératoire du moyen de coupe utilisé dans le dispositif de pose de manchons conforme à l'invention, avec les avantages importants qui en découlent, on va tout d'abord décrire un agencement de type traditionnel en référence à la
Le moyen de coupe 27' est alors constitué d'une pluralité (ici quatre) de lames de rasoir 28' agencées pour pivoter dans un plan commun qui est le plan de coupe. Chaque lame 28' est montée sur un porte-lame 62' muni d'un d'axe 61' qui est tourillonné sur une couronne tournante 55', et les lames 28' pivotent en synchronisme selon un même mouvement entre leur position de retrait et leur position de coupe.The cutting means 27 'then consists of a plurality (here four) of razor blades 28' arranged to pivot in a common plane which is the cutting plane. Each blade 28 'is mounted on a blade holder 62' provided with an axis 61 'which is journalled on a rotating ring 55', and the blades 28 'rotate in synchronism in a single movement between their retracted position and their cutting position.
Le pivotement alterné de chaque lame 28' entre sa position de retrait et sa position de coupe est assuré au moyen d'un système de came 59' de type circonférentiel selon lequel un galet 59'.1 associé au porte-lame 62' de chaque lame 28' circule dans un chemin de came délimité sur 360° par des pistes coaxiales 59'.2, 59'.3 d'une couronne fixe 57'. En a) les quatre lames 28' sont en position de retrait. En b) et en c), la rotation dans la direction 101 de la couronne tournante 55' entraîne les galets 59.1, dont le coulissement dans le chemin de came circonférentiel fait pivoter lesdits galets et avec eux les porte-lame associés 62'. Comme indiqué plus haut, un tel agencement est incompatible avec des cadences très élevées, et l'usure des galets 59'.1 est rapide et difficile à contrôler.The alternating pivoting of each blade 28 'between its retracted position and its cutting position is ensured by means of a
L'invention permet de remédier à cette limitation grâce à un agencement selon lequel le pivotement alterné de la ou de chaque lame 28 entre sa position de retrait et sa position de coupe est assuré au moyen d'un système de came 29 par la différence de rotation de deux couronnes tournantes superposées 55, 57 constituant le support de ladite lame, dont l'une (ici la couronne supérieure 55) présente un chemin de came rectiligne 60 parallèle au plan de coupe P et de direction oblique, dans lequel coulisse une came allongée 59.1 qui est solidaire en rotation du porte-lame 62 par l'intermédiaire d'un axe 61 qui est parallèle à l'axe commun X des couronnes 55, 57 et tourillonné sur l'autre couronne tournante 57.The invention overcomes this limitation through an arrangement in which the alternating pivoting of the or each
Le support du moyen de coupe 29 est ainsi constitué de deux couronnes tournantes superposées 55, 57 entraînées en rotation autour de l'axe X (flèche 101), le déphasage en alternance entre ces deux couronnes générant le mouvement des porte-lame 62 grâce au système de cames 59 relié à l'axe 61, lequel axe est couplé à une came coulissante 29.1 associée passant dans un chemin de came 60 agencé dans la couronne supérieure 55. Cet agencement est mieux visible sur la vue partielle de la

En b), la pointe 68 de chaque lame 28 arrive au contact de la paroi de gaine 13 pour percer ladite paroi.In b), the
En c), chaque lame 28 est en position de coupe.In c), each
Si l'on se réfère maintenant au détail de la
Pour y remédier, l'invention propose une solution plus performante, avec ici deux modes d'exécution donnés à titre d'exemple non limitatif, respectivement illustrés aux
Ainsi, l'agencement de l'extrémité libre de chaque lame 28 est tel que la paroi de la gaine 13 est d'abord percée, puis coupée en étant tirée radialement vers l'extérieur lors de la rotation du support de lame autour de l'axe X du conformateur 20, ce qui évite à chaque lèvre de coupe d'être repoussée à l'intérieur de la gorge 24, avec les inconvénients qui ont été relevés plus haut au regard des techniques antérieures.Thus, the arrangement of the free end of each
Une première façon d'assurer cette double fonction de coupe et de tirage de la paroi coupée dans une direction radialement extérieure consiste à prévoir que l'extrémité libre, notée 65, de la ou de chaque lame de coupe 28 est conformée en bec crochu, comme cela est illustré aux
Cette conformation en bec crochu est bien visible sur les
On notera sur la
Ainsi que cela est mieux visible sur la vue de la
Une autre façon d'assurer la double fonction de coupe et de tirage de la paroi coupée dans une direction radialement extérieure consiste à prévoir que l'extrémité libre 65 de la ou de chaque lame 28 présente un bord de coupe 66 qui est rectiligne, et dont la direction définit la tangente au bord de coupe Δ, et avec une direction de la lame qui est modifiée (par exemple en modifiant la direction de la glissière 63 du porte-lame 62) pour conserver un angle α qui est inférieur à 90°, par exemple de 60° à 80°, contrairement à l'agencement des
Ceci est illustré aux
Comme cela est visible sur la vue de détail de la
Dans le cadre de l'invention, on a ainsi prévu un support constitué de deux couronnes tournantes superposées 55, 57, entraînées en rotation autour de l'axe X par les courroies respectives 56, 58 qui sont reliées à l'arbre de sortie des moteurs d'entraînement précités 48, 49. Les deux couronnes superposées 55, 57 sont entraînées en rotation à des vitesses proches l'une de l'autre, avec un léger déphasage en alternance qui est ici piloté par le programmateur électronique commun 50. En effet, on constate que le système de cames 59, avec ses cames 59.1 coulissant dans leur chemin de came 60, est agencé de telle façon qu'une différence de vitesse de rotation (dans un sens ou dans un autre) entre les couronnes 55, 57 imprime un mouvement à chaque came du système de cames 59, et par suite un pivotement de chaque porte-lame 62 autour de son axe X1. Ainsi, le pilotage des déphasages angulaires entre les couronnes 55, 57 garantit une commande très précise du pivotement de chacune des lames 28 entre leur position de retrait et leur position de coupe. Le pivotement alterné des lames 28 est donc parfaitement contrôlé, en vitesse et en position, par la différence de rotation des deux couronnes superposées 55, 57.In the context of the invention, there is thus provided a support consisting of two superimposed

On est ainsi parvenu à réaliser un dispositif de pose de manchons sur des objets en défilement qui perfectionne sensiblement le dispositif antérieur du document
La machine de pose permet une utilisation à des cadences très élevées, par exemple 600 coups par minute, et ce avec des gaines dont le film constitutif est de faible épaisseur, par exemple 25 µm, et de basse densité, par exemple une densité inférieure à 1.The laying machine allows use at very high speeds, for example 600 rounds per minute, and with sheaths whose constituent film is thin, for example 25 microns, and low density, for example a density less than 1.
L'invention n'est pas limitée au mode de réalisation qui vient d'être décrit, mais englobe au contraire toute variante reprenant, avec des moyens équivalents, les caractéristiques essentielles énoncées plus haut.The invention is not limited to the embodiment which has just been described, but on the contrary covers any variant using, with equivalent means, the essential characteristics mentioned above.
