Description

L'invention concerne un appareil simplifié de distribution et de coupe simultanées de bandes de matériaux enroulés, avec changement automatique du rouleau en service.The invention relates to a simplified apparatus for the simultaneous distribution and cutting of strips of wound material, with automatic change of the roll in service.

L'objet de l'invention se rattache au secteur technique des moyens de distribution de longueurs déterminées de bandes enroulées sur bobine ou noyau. En particulier, mais non limitativement, l'invention s'applique aux appareils de distribution et de coupe simultanées de papier, ouate, et autres matériaux d'essuyage.The object of the invention relates to the technical sector of the means for distributing determined lengths of strips wound on reel or core. In particular, but not limited to, the invention applies to apparatus for the simultaneous distribution and cutting of paper, wadding, and other wiping materials.

L'appareil est du type bien connu selon lequel le rouleau de matériau en service est appliqué de préférence en pression directement sur un tambour à surface anti-glissante, afin que par simple traction manuelle sur la bande de matériau débordant de l'appareil, on distribue et on coupe automatiquement une bande dont la longueur est sensiblement égale au diamètre du tambour, cela par un dispositif de coupe dentelé qui est associé au tambour et fait saillie hors du tambour lor- qu'on l'entraîne en rotation par traction sur le matériau, de manière à pénétrer dans le matériau ainsi tendu de part et d'autre du dispositif de coupe. Après la coupe le tambour lancé, revient à sa position initiale par l'intermédiaire d'organes complémentaires, et une nouvelle bande de matériau déborde de l'appareil.The apparatus is of the well known type according to which the roll of material in service is preferably applied under pressure directly to a drum with an anti-slip surface, so that by simple manual pulling on the strip of material overflowing from the apparatus, a strip whose length is substantially equal to the diameter of the drum is automatically dispensed and cut by a serrated cutting device which is associated with the drum and projects out of the drum when it is rotated by traction on the material, so as to penetrate the material thus stretched on either side of the cutting device. After cutting the drum launched, returns to its initial position by means of complementary members, and a new strip of material overflows from the device.

Dans certains cas d'utilisation de ce type d'appareils, il est nécessaire d'installer des appareils peu encombrants en profondeur, distribuant des bandes de largeur étroite à partir de rouleaux de grand diamètre, et autorisant le changement automatique de rouleaux.In certain cases of use of this type of device, it is necessary to install space-saving devices at depth, distributing strips of narrow width from large diameter rollers, and allowing the automatic change of rollers.

Pour répondre à ces impératifs, on a créé un nouvel appareil de coupe et de distribution simultanées, à partir du tambour d'entraînement à surface anti-glissante, dans lequel se déplace l'organe de coupe comme indiqué plus haut.To meet these requirements, a new simultaneous cutting and distribution device has been created from the non-slip surface drive drum, in which the cutting member moves as indicated above.

On cite au titre de l'art antérieur le plus proche au titre de l'article 54.2 de la CBE, le brevet européen 0 116 508 appartenant au déposant de la Demande - le préambule de la revendication principale tient compte de ce brevet.

  • - Selon l'invention l'appareil de distribution et de coupe simultanées de bandes de matériaux enroulés comprend un carter avec parois avant, arrière, latérales et de fond avec changement automatique du rouleau en service, du type selon lequel le rouleau de matériau en service est appliqué en appui directement sur un tambour d'entraînement agencé avec un dispositif de coupe escamotable extérieurement afin que par simple traction manuelle sur la bande libre de matériau débordant d'une ouverture du carter sous l'appareil après s'être enroulée sur le tambour, on distribue et on coupe automatiquement une bande dont la longueur est sensiblement égale au diamètre du tambour, un rouleau de réserve étant disposé au-dessus du rouleau de service en attente de la finition dudit rouleau de service susceptible d'être évacué dans un magasin de stockage, ledit rouleau de réserve étant disposé sur un volet support réglable en position, ledit volet étant articulé et étant asservi à un ensemble de moyens de transmission et de verouillage pour assurer soit la retenue du rouleau de réserve, soit sa mise en place automatique en appui sur le tambour après évacuation du rouleau de service presque vide, ledit appareil étant caractérisé en ce que:
  • - le rouleau de service posé sur le tambour d'entraînement est également en appui à roulement sur un cylindre rotatif par rapport auxdites parois avant et arrière du carter; la bande libre à tirer débordant de l'ouverture du carter après être passé entre deux rouleaux fous;
  • - le rouleau de service reçoit dans son noyau ou mandrin un moyen de poussée lui conférant une force de poussée d'intensité constante vers le bas pour l'éjecter entre le tambour et le cylindre dans le magasin de stockage.
  • - lesdits moyens de transmission et de verouillage sont actionnés par un moyen de commande, sollicité lui -même par les moyens de poussée.
Under the closest prior art under Article 54.2 of the EPC, European patent 0 116 508 belonging to the applicant is cited - the preamble to the main claim takes this patent into account.
  • - According to the invention, the apparatus for simultaneously distributing and cutting strips of wound material comprises a casing with front, rear, side and bottom walls with automatic change of the roll in service, of the type according to which the roll of material in use is applied directly against a drive drum arranged with an externally retractable cutting device so that by simple manual pulling on the free strip of material projecting from an opening of the casing under the device after being wound on the drum , a strip is automatically dispensed and cut, the length of which is substantially equal to the diameter of the drum, a reserve roll being placed above the service roll awaiting the completion of said service roll capable of being removed to a store storage, said reserve roller being disposed on a support flap adjustable in position, said flap being articulated and being slaved to a set of means of transmission and locking to ensure either the retention of the reserve roller, or its automatic positioning by pressing on the drum after evacuation of the almost empty service roller, said apparatus being characterized in that:
  • - The service roller placed on the drive drum is also bearing bearing on a rotary cylinder relative to said front and rear walls of the housing; the free strip to be drawn overflowing from the opening of the casing after having passed between two idle rollers;
  • - The service roller receives in its core or mandrel a pushing means giving it a constant downward pushing force to eject it between the drum and the cylinder in the storage magazine.
  • - Said transmission and locking means are actuated by a control means, itself solicited by the pushing means.

Pour certains cas d'utilisation, il est nécessaire de modifier le dispositif sensible au poids du rouleau presque vide et de le combiner avec un dispositif remplaçant le lestage des mandrins.For certain use cases, it is necessary to modify the device sensitive to the weight of the almost empty roller and to combine it with a device replacing the ballasting of the mandrels.

Pour cela, le dispositif support du rouleau neuf en attente établi sous la forme d'un volet articulé sur les parois latérales du carter, est associé à un ensemble de moyens pivotants par rapport à la plaque de fond du carter et combinés entre eux pour assurer soit la retenue dudit rouleau neuf, soit sa mise en place automatique en appui sur le tambour à surface anti-glissante et sur le cylindre rotatif après éjection automatique du rouleau presque vide, avec mise en pression également automatique du rouleau neuf. Ces caractéristiques et d'autres encore ressortiront bien de la description qui suit.For this, the support device for the new standby roller established in the form of a hinged flap on the side walls of the casing, is associated with a set of pivoting means relative to the bottom plate of the casing and combined together to ensure either the retention of said new roller, or its automatic positioning by pressing on the drum with non-slip surface and on the rotary cylinder after automatic ejection of the almost empty roller, with also automatic pressurization of the new roller. These characteristics and others will become apparent from the description which follows.

A l'intérieur du tambour est disposé parallèlement à l'axe de rotation une barrette (8) de longueur un peu supérieure à celle du tambour, de manière à ce que dans une position de fonctionnement de l'extrémité (8a) la barrette repose dans une ouverture (3g) du flasque (3C) en ne dépassant pas à l'extérieur, tandis que l'autre extrémité (8b) passe à travers une ouverture (3h) du flasque (3b) en débordant jusqu'à proximité de la paroi arrière (1a) du carter (figure 5).Inside the drum is arranged parallel to the axis of rotation a bar (8) of length a little greater than that of the drum, so that in an operating position of the end (8a) the bar rests in an opening (3g) of the flange (3C) while not projecting outside, while the other end (8b) passes through an opening (3h) of the flange (3b) projecting up to near the rear wall (1a) of the casing (FIG. 5).

Comme on l'explique par la suite, dans une autre phase de fonctionnement, c'est l'extrémité (8a) qui déborde à l'extérieur du tambour, tandis que l'extrémité (8b) est escamotée, cela pour coopérer alternativement avec une butée (9) solidaire de la paroi arrière (1a) ou avec une rampe (10) solidaire de la paroi avant (1 b).As explained below, in another operating phase, it is the end (8a) which projects beyond the outside of the drum, while the end (8b) is retracted, this in order to cooperate alternately with a stop (9) secured to the rear wall (1a) or with a ramp (10) secured to the front wall (1b).

Dans lesdites phases de fonctionnement, la barrette (8) coopère également par une saillie (8c), avec une butée (11) située à l'intérieur du tambour, et un ressort (12) convenablement disposé rappelle la barrette en position de butée.In said operating phases, the bar (8) also cooperates by a projection (8c), with a stop (11) located inside the drum, and a spring (12) suitably arranged recalls the bar in the stop position.

Pour ce qui concerne le tambour (3), on voit encore qu'il présente au centre une gorge périphérique (3i) pour loger une courroie (13) qui est enroulée dans une gorge (14a) établie au centre d'un rouleau inférieur (14) porté à rotation libre par les parois avant et arrière du carter. Un autre rouleau similaire (15) est monté de la même manière à côté du premier en laissant entre eux un espace suffisant pour le passage du matériau à distribuer mais trop faible pour le passage accidentel des doigts de l'utilisateur, afin d'éviter leur contact éventuel avec la lame de coupe pendant sa rotation. Les rouleaux (14 et 15) sont de préférence fixés en léger débordement dans l'ouverture (1e) du fond du carter pour être actionnés au besoin manuellement.As far as the drum (3) is concerned, it can also be seen that it has in the center a peripheral groove (3i) for accommodating a belt (13) which is wound in a groove (14a) established in the center of a lower roller ( 14) carried with free rotation by the front and rear walls of the casing. Another similar roller (15) is mounted in the same way next to the first, leaving between them sufficient space for the passage of the material to be dispensed but too small for the accidental passage of the user's fingers, in order to avoid their possible contact with the cutting blade during its rotation. The rollers (14 and 15) are preferably fixed in slight overflow in the opening (1e) of the bottom of the housing to be actuated if necessary manually.

Le premier rouleau (R1) de matériau à débiter est simplement placé en appui sur un berceau composé de trois éléments, à savoir: le tambour (3), un cylindre rotatif (16) porté à rotation libre sur les parois avant et arrière du carter, et un déflecteur (17) solidaire d'une paroi latérale (1c) du carter.The first roll (R1) of material to be cut is simply placed in abutment on a cradle composed of three elements, namely: the drum (3), a rotary cylinder (16) carried with free rotation on the front and rear walls of the casing , and a deflector (17) secured to a side wall (1c) of the casing.

En avant du cylindre (16) est disposée une palette (18) dont les bras d'extrémités (18a) (18b) sont articulés en (19) sur les parois avant et arrière du carter, près de l'axe de rotation du cylindre, tandis que la partie médiane (18c) s'étend en direction du tambour. Du côté de la paroi arrière du carter, le bras (18b) présente une ouverture ovalisée (18d) coopérant avec un doigt (20a) porté par une tige verticale (20) remontant vers la partie supérieure de la paroi (1a) du carter en étant guidée avec un jeu par un étrier (21) ou moyen similaire (figure 3). Un ressort (22) relie le doigt (20a) à un point fixe inférieur du carter pour rappeler la tige (20) vers le bas et la palette (18) en position haute, du fait de la position excentrée du doigt (20a) par rapport aux points de la rotation (19) de la palette.In front of the cylinder (16) is arranged a pallet (18) whose end arms (18a) (18b) are articulated at (19) on the front and rear walls of the casing, near the axis of rotation of the cylinder , while the middle part (18c) extends in the direction of the drum. On the side of the rear wall of the housing, the arm (18b) has an ovalized opening (18d) cooperating with a finger (20a) carried by a vertical rod (20) rising towards the upper part of the wall (1a) of the housing in being guided with play by a stirrup (21) or similar means (Figure 3). A spring (22) connects the finger (20a) to a lower fixed point on the housing to bring the rod (20) down and the pallet (18) in the high position, due to the eccentric position of the finger (20a) by relative to the points of rotation (19) of the pallet.

A la partie supérieure, la tige (20) présente un décrochement (20b) pour passer à côté d'une saillie (1f) de la paroi du carter sur laquelle s'appuie un crochet (23) articulé en (23b) à ladite paroi, et dont l'extrémité active (23a) retient en position normale une partie en débordement (24a) formée sur un volet incliné (24) qui est articulé à son extrémité opposée en (25 et 26) sur les parois du carter (figures 1 et 3).At the upper part, the rod (20) has a recess (20b) for passing beside a projection (1f) of the wall of the casing on which a hook (23) articulated at (23b) on said wall rests. , and whose active end (23a) retains in normal position an overflowing part (24a) formed on an inclined flap (24) which is articulated at its opposite end at (25 and 26) on the walls of the casing (Figures 1 and 3).

On voit que la partie en débordement (24a) du volet traverse une ouverture en arc de cercle (1g) de la paroi du carter, et qu'un doigt (24b) du volet situé près de son articulation supérieure (26) traverse également une ouverture en arc de cercle (1h) de la paroi; ce doigt étant relié au crochet (23) par ressort (27).It can be seen that the projecting part (24a) of the flap crosses an opening in an arc (1g) of the wall of the casing, and that a finger (24b) of the flap located near its upper articulation (26) also crosses a opening in an arc (1h) of the wall; this finger being connected to the hook (23) by spring (27).

Comme on le comprend, le volet (24) est destiné à retenir en attente, au-dessus du rouleau (R1) en service, un deuxième rouleau (R2) qui est coincé entre ce volet et une paroi latérale (1c) du carter.As can be understood, the flap (24) is intended to hold on standby, above the roller (R1) in service, a second roller (R2) which is wedged between this flap and a side wall (1c) of the casing.

On décrit maintenant le fonctionnement de l'appareil en se référant aux figures des dessins.The operation of the apparatus will now be described with reference to the figures in the drawings.

Pour la mise en service de l'appareil, on pose le rouleau (R1) sur le tambour (3), le cylindre (16) et le déflecteur (17), et on fait sortir la bande libre sous l'appareil en actionnant le tambour à l'aide d'un bouton (7) ou éventuellement le rouleau (14).To put the device into service, put the roller (R1) on the drum (3), the cylinder (16) and the deflector (17), and the free strip is brought out under the apparatus by actuating the drum using a button (7) or possibly the roller (14).

En tirant sur la bande débordante, on provoque l'entraînement en rotation sous glissement du tambour du fait que celui-ci présente à sa périphérie une surface accrocheuse du type toile émeri par exemple.By pulling on the protruding strip, the drum is caused to rotate under sliding of the fact that the latter has at its periphery a catchy surface of the emery cloth type for example.

Pendant cette rotation du tambour, la lame de coupe (4) qui est escamotée à l'intérieur du tambour prend appui par sa partie (4b) sur la came (6) dont le profil est étudié pour que après passage sous le rouleau (R1), la lame sorte du tambour et pénètre dans la bande de matériau. En position de sorte maximum (figure 2), et du fait que la bande est tendue de part et d'autre par l'effet de traction manuelle et d'appui du rouleau sur le tambour combiné avec la rotation, la bande est détachée, et le tambour libéré continue sa rotation, tandis que la lame s'escamote de nouveau dans le tambour.During this rotation of the drum, the cutting blade (4) which is retracted inside the drum bears by its part (4b) on the cam (6) whose profile is studied so that after passing under the roller (R1 ), the blade comes out of the drum and enters the strip of material. In the maximum position (Figure 2), and the fact that the strip is stretched on both sides by the effect of manual traction and support of the roller on the drum combined with the rotation, the strip is detached, and the released drum continues to rotate, while the blade retracts back into the drum.

Lorsque le tambour atteint la position selon laquelle la lame de coupe est escamotée et située en arrière du rouleau de matériau, la barrette (8) qui est maintenue par la butée (11) et le ressort incliné (12) dans la position ou l'extrémité profilée (8b) déborde du tambour, s'appuie par ladite extrémité contre la butée (9), comme on le voit aux figures 5, 6, 7, en arrêtant ainsi le tambour.When the drum reaches the position in which the cutting blade is retracted and located behind the roll of material, the bar (8) which is held by the stop (11) and the inclined spring (12) in the position or the profiled end (8b) protrudes from the drum, bears by said end against the stop (9), as seen in Figures 5, 6, 7, thereby stopping the drum.

Par réaction, dûe au ressort de rappel (12), la barrette se déplace dans l'ouverture de passage (3h) et, sous l'effet du ressort, s'escamote à l'intérieur du tambour, tandis que l'autre extrémité (8a) de la barrette vient à son tour en débordement.By reaction, due to the return spring (12), the bar moves in the passage opening (3h) and, under the effect of the spring, retracts inside the drum, while the other end (8a) of the bar in turn comes into overflow.

L'appareil est alors prêt pour être de nouveau utilisé.The device is then ready to be used again.

Lorsqu'on tire une nouvelle bande en faisant tourner le tambour, l'extrémité débordante et profilée (8a) de la barrette s'appuie contre la rampe (10) de la paroi avant du carter (figures 8, 9, 10) et ladite barrette est repoussée pour être replacée dans la position où l'extrémité (8b) déborde, en vue de l'arrêt du tambour après la coupe.When a new strip is pulled by rotating the drum, the protruding and profiled end (8a) of the bar rests against the ramp (10) of the front wall of the casing (Figures 8, 9, 10) and said bar is pushed back to be replaced in the position where the end (8b) overflows, in order to stop the drum after cutting.

Lorsque le rouleau (R1) est presque fini c'est-à-dire lorsqu'il ne reste que quelques longueurs de bande à distribuer autour du mandrin ou noyau (A), ce dernier peut reposer sur la palette (18), s'étendant entre le tambour (3) et le cylindre (16). Mais le poids du mandrin n'est pas suffisant pour faire pivoter la palette, c'est pourquoi on prévoit de lester le mandrin soit par introduction d'un barreau indépendant (29), soit par mise en oeuvre d'un mandrin lui-même lesté. A noter que ce poids supplémentaire du rouleau évite tout glissement sur le tambour hors de la traction manuelle, lorsque le rouleau est très largement entamé donc moins lourd.When the roller (R1) is almost finished, that is to say when there are only a few lengths of tape to distribute around the mandrel or core (A), the latter can rest on the pallet (18), extending between the drum (3) and the cylinder (16). But the weight of the mandrel is not sufficient to rotate the pallet, this is why it is planned to ballast the mandrel either by introduction of an independent bar (29), or by implementation of a mandrel itself ballasted. Note that this additional weight of the roller prevents any slipping on the drum outside of manual traction, when the roller is very largely started therefore less heavy.

Le mandrin ainsi lesté fait pivoter la palette (18) qui par son bras (18b) repousse alors vers le haut la tige (21) à l'encontre de son ressort de rappel (22).The mandrel thus ballasted rotates the pallet (18) which by its arm (18b) then pushes upwards the rod (21) against its return spring (22).

L'extrémité supérieure (20b) de la tige soulève le crochet (23) en libérant ainsi le volet (24) qui sous l'effet du poids du rouleau (R2) en attente, pivote vers le bas en parcourant l'ouverture (1g). Le rouleau (R2) prend alors la place du rouleau (R1) qui est tombé dans un réceptacle inférieur (30). Parallèlement, le ressort (22) a rappelé la tige (20) vers le bas et la palette (18) en position haute, tandis que le ressort (27) rappelle également le volet (24) en position de verrouillage par le crochet (23).The upper end (20b) of the rod lifts the hook (23), thereby releasing the flap (24) which, under the effect of the weight of the waiting roller (R2), pivots downwards by traversing the opening (1g ). The roller (R2) then takes the place of the roller (R1) which has fallen into a lower receptacle (30). At the same time, the spring (22) returns the rod (20) downwards and the pallet (18) in the high position, while the spring (27) also returns the flap (24) in the locking position by the hook (23 ).

En effectuant alors une nouvelle traction manuelle sur la bande débordante (R1), le rouleau (R2) sera entraîné par le tambour (3) et on distribuera alors deux bandes simultanément jusqu'à ce que le rouleau (R1) soit fini.By then carrying out a new manual traction on the overflowing strip (R1), the roller (R2) will be driven by the drum (3) and two strips will then be distributed simultaneously until the roller (R1) is finished.

En variante, notamment si l'on veut appliquer l'invention pour distribuer des bandes de plus grande largeur, il peut être intéressant de remplacer le dispositif comprenant la barrette (8), les butées (9) et (11), la rampe (10) et le ressort (12) par les dispositions connues par de précédentes demandes dont le déposant est également le titulaire notamment la demande européenne 85.02873, c'est-à-dire mettant en oeuvre un parachute, un cliquet des butées fixes ou mobiles, et des moyens de guidage, associés à la rotation du tambour, en les aménageant pour correspondre à la structure de la présente invention.As a variant, in particular if one wishes to apply the invention to distribute strips of greater width, it may be advantageous to replace the device comprising the bar (8), the stops (9) and (11), the ramp ( 10) and the spring (12) by the arrangements known from previous requests of which the applicant is also the holder, in particular European application 85.02873, that is to say using a parachute, a pawl of the fixed or mobile stops, and guide means, associated with the rotation of the drum, arranging them to correspond to the structure of the present invention.

Selon une autre variante illustrée aux figures 11 à 15 et pour certains cas d'utilisation, le dispositif sensible au poids du rouleau presque vide est modifié et est combiné avec un dispositif remplaçant le lestage des mandrins.According to another variant illustrated in FIGS. 11 to 15 and for certain use cases, the device sensitive to the weight of the almost empty roller is modified and is combined with a device replacing the ballasting of the mandrels.

A cet effet le deuxième rouleau (R2) qui est posé en attente sur le volet (24) articulé à une extrémité en (25 et 26) sur les parois latérales du carter, présente à son autre extrémité un galet cannelé (48) pouvant se déplacer dans une ouverture (1g) en arc de cercle ayant pour centre les axes (25 - 26).To this end, the second roller (R2) which is placed on standby on the flap (24) articulated at one end at (25 and 26) on the side walls of the casing, has at its other end a fluted roller (48) which can be move in an opening (1g) in an arc with the axes (25 - 26) at the center.

Un bras (46) articulé en (47) sur la paroi (1a) du carter, s'appuie par son extrémité libre profilée et sous l'effet d'un ressort de rappel (31), sous le galet (48). Lorsque le rouleau (R2) est posé sur le volet, ce dernier pivote sous le poids (traits interrompus figure 1) jusqu'à ce que le galet (48) soit arrêté par la partie saillie (32a) d'une butée (32) montée pivotante en (33) sur la paroi (1a) du carter, avec rappel en position haute par un ressort (34).An arm (46) articulated at (47) on the wall (1a) of the housing, is supported by its profiled free end and under the effect of a return spring (31), under the roller (48). When the roller (R2) is placed on the flap, the latter pivots under the weight (broken lines in Figure 1) until the roller (48) is stopped by the projection (32a) of a stop (32) pivotally mounted at (33) on the wall (1a) of the housing, with return to the high position by a spring (34).

Sur l'axe (33) s'articule également l'extrémité d'une biellette (35) qui est reliée par son autre extrémité à un support (36) dont l'extrémité inférieure forme une chape (36a) pour l'articulation d'un doigt profilé (37) qui est maintenu en position horizontale par un ressort concentrique (38). La biellette (35) est rappelée vers le bas par un ressort (39) et porte une saillie profilée (35a) destinée à coopérer dans une phase de fonctionnement avec un crochet (40) suspendu librement en (41) au bras (46).On the axis (33) is also articulated the end of a link (35) which is connected by its other end to a support (36) whose lower end forms a yoke (36a) for the articulation of 'a profiled finger (37) which is held in a horizontal position by a concentric spring (38). The link (35) is returned downwards by a spring (39) and carries a profiled projection (35a) intended to cooperate in an operating phase with a hook (40) suspended freely at (41) on the arm (46).

Comme on le voit encore aux figures des dessins, le doigt (37) peut se déplacer dans une ouverture (1i) de la paroi (1a) dimensionnée pour assurer le passage libre du doigt avec tous types de rouleaux de matériau, et traverse le noyau ou mandrin du rouleau dans lequel il s'appuie en pression.As can still be seen in the figures of the drawings, the finger (37) can move in an opening (1i) of the wall (1a) dimensioned for ensure the free passage of the finger with all types of rolls of material, and passes through the core or mandrel of the roll in which it is pressed.

On décrit maintenant le fonctionnement de l'appareil selon la variante des figures 11 à 15 en supposant qu'un rouleau (R1) est en service appliqué en pression sur le tambour (3) par le doigt (37), tandis qu'un rouleau (R2) est en attente, retenu par le volet (24) dont le galet (48) est en butée contre la saillie (32a).The operation of the apparatus according to the variant of FIGS. 11 to 15 will now be described by assuming that a roller (R1) is in service applied under pressure to the drum (3) by the finger (37), while a roller (R2) is on hold, retained by the flap (24) whose roller (48) is in abutment against the projection (32a).

Lorsqu'il ne reste plus que quelques longueurs de bandes à débiter, le mandrin du rouleau (R1), qui est poussé vers le bas par l'action du doigt (37), peut passer entre le tambour (3) et le cylindre (16) afin d'être réceptionné dans un magasin (30) où il continuera à débiter les bandes restantes.When there are only a few lengths of tape left to cut, the mandrel of the roller (R1), which is pushed down by the action of the finger (37), can pass between the drum (3) and the cylinder ( 16) in order to be received in a store (30) where it will continue to cut the remaining strips.

A noter que pour éviter toute inclinaison du mandrin sous l'effet du doigt-presseur (37), le cylindre (16) est monté légèrement incliné entre les parois (figure 4) pour assurer un jeu (j) du côté opposé au doigt.Note that to avoid any inclination of the mandrel under the effect of the pressing finger (37), the cylinder (16) is mounted slightly inclined between the walls (FIG. 4) to ensure a clearance (j) on the side opposite the finger.

Pendant le déplacement vers le bas du mandrin, donc de l'ensemble biellette (35), support (36) et doigt (37), un pion (35b) établi sur la biellette (35), bute contre un épaulement (32b) de la butée (32) et la fait pivoter vers le bas, ce qui à pour effet de libérer le galet (48) de sa butée (32a), donc de permettre le pivotement complet du volet (24) de retenue du rouleau (R2). Ledit rouleau tombe alors sur le tambour (3) et parallèlement, le crochet (40) accroche la saillie (35a) de la biellette (35), avant de remonter sous l'effet de rappel du bras (46). Le crochetage de la biellette entraîne vers le haut le support (36) du doigt (37) qui pivote verticalement pour longer le rouleau (R1) jusqu'à ce qu'il pénètre dans le mandrin dudit rouleau où il peut revenir en butée à la position horizontale sous l'effet du ressort (38). A cet instant, le crochet par réaction se libère de la saillie en permettant ainsi le relevage du volet (24) entrainé par le bras (46), et la mise en pression du rouleau (R2) par le doigt (37).During the downward movement of the mandrel, therefore of the link (35), support (36) and finger (37) assembly, a pin (35b) established on the link (35), abuts against a shoulder (32b) of the stop (32) and makes it pivot downwards, which has the effect of releasing the roller (48) from its stop (32a), therefore allowing the pivoting of the roller retaining flap (24) (R2) . Said roller then falls on the drum (3) and in parallel, the hook (40) hooks the projection (35a) of the link (35), before rising under the return effect of the arm (46). The hooking of the link pulls upwards the support (36) of the finger (37) which pivots vertically to follow the roller (R1) until it enters the mandrel of said roller where it can come back into abutment at the horizontal position under the effect of the spring (38). At this instant, the hook by reaction is released from the projection thus allowing the lifting of the flap (24) driven by the arm (46), and the pressurization of the roller (R2) by the finger (37).

L'appareil est alors prêt à recevoir un rouleau en attente pendant que se débite le rouleau mis en service, avec la fin du premier rouleau.The device is then ready to receive a waiting roll while the roll in service is being fed, with the end of the first roll.

A noter que le magasin (30) peut présenter une ouverture inférieure (30a) calibrée pour laisser passer seulement le mandrin lorsqu'il est vide et permettre ainsi son éjection automatique.Note that the magazine (30) may have a lower opening (30a) calibrated to let only pass the mandrel when it is empty and thus allow its automatic ejection.

On à encore prévu une variante de réalisation selon laquelle on peut placer en attente d'autres rouleaux de matériau d'essuyage avec mise en service automatique.An alternative embodiment has also been provided, according to which other rolls of wiping material can be placed on standby with automatic commissioning.

A la figure 15, on à illustré une réalisation à trois rouleaux. A cet effet, un deuxième volet (42) est monté pivotant au dessus et à l'opposé du volet (24). Ce volet présente une branche (42a) de l'autre côté de l'articulation, selon un angle déterminé, et dans sa partie médiane s'articule une tringle (43) qui est reliée à un troisième volet (44) monté pivotant, au dessus et du même côté que le volet (42).In Figure 15, there is illustrated an embodiment with three rollers. To this end, a second flap (42) is pivotally mounted above and opposite the flap (24). This flap has a branch (42a) on the other side of the articulation, at a determined angle, and in its middle part is articulated a rod (43) which is connected to a third flap (44) pivotally mounted, at above and on the same side as the flap (42).

Comme on le voit, les points d'attache de la tringle sont calculés pour que lorsque le volet (42) est abaissé par le passage du rouleau (R2) en appui sur le volet (24), le volet (44) est relevé pour retenir un troisième rouleau (R3).As can be seen, the attachment points of the rod are calculated so that when the flap (42) is lowered by the passage of the roller (R2) bearing on the flap (24), the flap (44) is raised to retain a third roller (R3).

Lorsque le rouleau (R2) est libéré par le volet (24), le volet (42) remonte par rappel d'un ressort (45), tandis que la tringle (43) tire le volet (44) pour permettre le transfert du rouleau (R3) sur le volet (42) qui bascule alors pour autoriser l'appui dudit rouleau sur le volet (24) tandis que le volet (44) remonte, prêt à recevoir un autre rouleau.When the roller (R2) is released by the flap (24), the flap (42) rises by return of a spring (45), while the rod (43) pulls the flap (44) to allow the transfer of the roller (R3) on the flap (42) which then switches to authorize the pressing of said roller on the flap (24) while the flap (44) goes back up, ready to receive another roller.

Les avantages ressortent bien de la description, on souligne notamment la simplification de l'appareil par rapport aux appareils existants, le fonctionnement doux et précis, le chargement automatique de rouleaux augmentant la capacité de l'appareil, le chargement facile et rapide de l'appareil par l'absence de tout support de rouleau, le faible encombrement en profondeur, l'éjection automatique du mandrin vide, la mise en pression permanente du rouleau en service.The advantages emerge clearly from the description, in particular the simplification of the device is emphasized compared to existing devices, the smooth and precise operation, the automatic loading of rollers increasing the capacity of the device, the easy and fast loading of the device by the absence of any roller support, the small space requirement, the automatic ejection of the empty mandrel, the permanent pressurization of the roller in service.

Apparatus as claimed in Claim 1, characterized in that the roll in use (R1) accommodates within the spindle or core (4) thereof a ballast (29) which, when the roll in use is nearly empty, controls the putting into operation of the second roll (R2), said roll (R1) being in abutment on the control means actuating said transmission and interlocking means, said control means being a palette (18) mounted pivotally at (19) on the front and rearward walls of the casing, an arm (18b) of said palette having an oblong opening (18d) which co-operates with the intermediary transmission and interlocking means (20) consisting of a finger (20a) integral with a rod (20) guided vertically rearwardly of the rear wall (1a ) of the casing, the upper end of said rod, when the palette (18) is pivoted downwardly, cooperating with the means associated with the flap (24) for holding back the spare roll (R2).
5. Apparatus as claimed in Claim 4, characterized in that the roll supporting flap (24) is associated with contoured pivotal means with an arched opening, and is linked hingedly at the upper portion thereof on the walls of the casing, and extends downwardly in a slanted manner in order to wedge the roll between this flap itself and a side wall (1c) of the casing, said flap, at the lower portion thereof, being provided, on the side opposite the rearward wall (1a) of the casing, with means consisting of a projection (24a) extending through an arched opening (1g) of the wall and co-operating with the actuating portion (23a) of the hook (23), a spring (2, 7) secured to the flap and to the hook returning the flap in the interlocking position after the falling down of the roll (R2).
6. Apparatus as claimed in Claim 1, characterized in that the assembly of the means for the automatic changeover of the rolls includes for holding back the spare roll (R2) a device consisting of a contoured arm (46) abutted elastically under a roller (48) which is connected to the flap (24) and is capable of being moved through an arched opening (1g), the end of the arm (46) being abutted on the projection (32a) of a movable stop (32) when laid roll is resting on the flap.
7. Apparatus as claimed in Claim 6, characterized in that the means (37) imparting an urging force to the roll in use has the function of a control means for the actuation of the transmission and interlocking means, said means (37) being a finger which is mounted hingedly linked directly on the end of a support (36) which is in turn linked hingedly to the end of a small connecting rod (35) supported by the same supporting pin as the stop (32), and returned elastically in the pressure or urging position by the finger (37) engaged within the spindle of the roll of material.
8. Apparatus as claimed in Claim 7, characterized in that the assembly of the means for the automatic changeover of the rolls includes a device for releasing the waiting roll (R2) consisting of a stud (35b) supported by the small connecting rod (35) and coming in abutment against a shoulder (32b) of the stop (32) in order to cause this stop to be pivoted when the nearly empty roll (R1) is moved along between the drum (3) and the cylinder (16), while dricing along thereby the finger (37) together with the support (36) thereof and the small connecting (35).
9. Apparatus as claimed in Claim 8, characterized in that the assembly of the means for the automatic changeover of the rolls includes a device for the automatic return of the finger (37) in the position of abutment within the spindle of the fresh roll placed in the position of use (R2), said device consisting of a hook (40) hanging freely to the arm (46) and co-operating with a projection (35a) of the small connecting rod (35) when the roll (R1) is moved along between the drum (3) and the cylinder (16), the arm (46), returned during this step of co-operation by the spring (31) thereof, pulling then upwardly the assembly consisting of the finger (37), the support (36) the small connecting rod (35) and the hook (40), the finger (37) pivoting vertically in order to be moved along past the roll (R2) and to penetrate within the spindle of said roll, whereby the hook (40), on completion of the movement, is made free by reaction from the projection (35a), in order to permit the pressure setting of the finger owing to the action exerted by the return spring (39) of the small connecting rod (35).
10. Apparatus as claimed in Claim 7, characterized in that the rotational cylinder (16) is mounted in a slightly slanting position relative to the drum (3), in order to provide a passage clearance for the nearly empty roll against the action of the finger (37).
11. Apparatus as claimed in Claim 1, characterized in that a plurality of rolls is placed in a waiting position above the roll in use, said rolls in a waiting position being automatically transferred towards the drum (3) by an assembly of pivotal means (42 - 44), which are combined together in order to provide the transfer of the rolls in succession.
