- the breaking of the line of pre-cutting is ensured by the acceleration of the batch on which the adhesive strip is applied relative to the upstream conveyor carrying a line of packaging at the distribution station, this acceleration being obtained by the downstream drive means which cause the packaging batch to a linear speed greater than that of movement of the upstream conveyor.
- the speed differential between the upstream conveyors and downstream requires fine and regular adjustments, failing which the rupture of the section is not carried out in perfect condition.
- the object of the present invention is to provide a device for displacement of an adhesive strip, usable among other things for distribution strip sections on packaging or moving articles which remedies the disadvantages of current devices and, in particular, eliminates the distribution stops following blockages by wedging the belt or sections.

- each label is separated from the strands by peeling rollers which, despite their small contact surface with each label, are sources of incident, by sticking and accumulation on them of tags.
- the document DAS 1 116 145 relates to a device for distribution of pre-glued stanioles in the trajectory of the bottle neck in displacement. After gluing and cutting, the staniole is transferred to two spaced belts connected to the same motor means, and more precisely is pressed, by its longitudinal edges, on the external face of vertical strands spaced by two belts describing endless paths of on either side of the pass path.
- the songs of the two belts are in different planes, parallel to each other, but perpendicular to the band.
- the belts move step by step so as to bring the first staniole in the trajectory of a pass which takes it in passing, before brushes fold the sides of this staniole against the neck of the bottle.

- the present invention implements these drive means in organizing them differently.
- the two drive means are arranged so that the active strand which, in each of them, cooperates with the face tape adhesive, either straight, parallel, spaced from active strand juxtaposed with the other drive means, and has a song arranged substantially in the same plane as that of the active strand of the means juxtaposed drive, this plane being parallel and coincident with that of the strip, these two active strands facing each other being spaced from each other by a distance less than the width of the adhesive strip so that their edges cooperate with the longitudinal edges of said strip.
- the adhesive tape is moved only by its temporary bonding on the strands of the two drive means. From this done, the adhesive side is protected during its movement and does not risk stick to a surface of the device, generating incidents of distribution.
- the provision of drive means with belts substantially in the same plane and on either side of the strip in scrolling allows the strands to separate from the adhesive side by generating two opposite forces which, perpendicular to the longitudinal edges of the tape, cancel each other and do not influence the tape exit trajectory.
- the endless drive means are arranged so that the tape movement path brings the free end of an extreme section in the path of packaging in displacement on a conveyor, upstream of a plating roller or brush, and the electric motor, common to the drive means, is controlled by a control means triggering its supply at the passage of each conditioning and stopping its feeding when a section length is unwound and is at least partially pressed against the packaging, to cause, by stopping the unwinding, the tearing of a line of precut formed between the strip and its extreme section.
- the free end of the extreme section pre-cut in the strip protrudes from the drive means and is arranged in the path of movement of the packaging in front receive this section and upstream of the brush or the plating roller.
- the adhesive side of it sticks to the conditioning, while simultaneously the means of driving the dispensing device are powered to deliver a length of tape corresponding to the length of a section.
- the drive means are stopped so that the effort of displacement communicated by the packaging to the glued strip section on it causes the pre-cutting line between the section and the band-Aid.
- the section is pressed by the brush or roller on the corresponding side of the packaging, while that the end of the next section protrudes in the displacement path packaging.
- This device works piecemeal, whatever the interval between two successive packages.
- the means for precutting the section in the strip are formed, on the one hand, by a blade arranged transversely between the two active strands of the unwinding means, this blade being connected to means able to move it alternately in one direction towards the strip, then in the other direction, under the control of control means reacting to the stopping of the reeling, and, on the other hand, by a fixed anvil against which slides the non-adhesive back of the strip.
- the reference numeral 2 denotes the plane of displacement of a roller conveyor on which packaging 3 are moved by drive means, and for example, by the strands spaced 4a, 5a of drive belts 4 and 5 circulating between a pulley drive 6 and a return pulley 7 and moving in the direction of arrow 8 in FIG. 2.
- 9 designates a reel of adhesive tape 10 whose face 10a wears adhesive.
- the means of displacement of the adhesive tape ensure the unwinding of the reel 9 and include two spaced drive means A and B each composed a belt 12, 13 circulating between a drive return wheel 14, 15 and a free return wheel 16, 17, by describing trajectories in the vertical plane, parallel to the strip to be moved.
- the two strands 12a, 13a which are opposite, are rectilinear, parallel and spaced by a distance less than the width of the strip 10, and are arranged so that their edge 12b, 13b, facing the band, either in the same plane as that of the other belt, this plane being parallel to the strip, so that, by plating to the by means of a roller 18 with a vertical axis, the adhesive longitudinal edges of the strip 10 temporarily stick against these longitudinal edges 12b, 13b.
- the driving wheels 14 and 15 are connected by a mechanism to gears 19 to a common electric motor 20 which is suitable for communicate, at belts 12 and 13, a movement of movement, in the direction of the arrows 21 and at a speed equal to the speed of movement of the packaging 3.
- This stepper or brushless motor is controlled by a control unit 22 which reacts to the stresses of a sensor 23, visible in FIG. 2, detecting the passage of each package 3 and to which it is connected by a circuit 24.
- the device comprises means carrying out a precut in the strip 10 unwound, means which, in the embodiment shown and as shown in more detail in Figure 3, are composed of a toothed blade 26 and an anvil 27, arranged on either side of the trajectory of movement of the strip 10.
- the blade 26 is disposed between the two strands 12a, 13a of the drive means A, B and is carried by a support 28, itself connected to means 29, capable of alternately moving the blade between a rest position, shown in Figure 3, and a working position in which it comes into contact with the strip 10, while pressing on the anvil 27. In this position, the blade makes a transverse precut line 30 extending over the greater part of the width of the adhesive strip 10, at the exception of the extreme zones Z, shown in FIG.
- the drive means 29 can be constituted by a pneumatic cylinder, by an electric cylinder or by an electromagnet.

- the blade 26 can also have a straight edge making a clear cut but constituting a precut due to the Z zones not cut.
- Figures 1 and 2 show that the frame 31, carrying the two drive means A and B, the roller 18 and the precut means 26 to 29, is disposed laterally to the path of movement of the packages 3 represented by the arrow 8 in FIG. 2 and by forming, with respect to this trajectory, an angle a which, in the embodiment shown, is acute, but can also be straight, if the environment allows it.
- the control unit 22, regulating the supply of the motor electric stepper 20, is designed to stop supplying this motor when the free end 32 of the section 33 projecting from the downstream ends of the drive means A and B comes in the path of movement of packaging 3, that is to say occupies the position shown in FIG. 1.
- the adhesive side of this section sticks to the end of the packaging, and in this case against its longitudinal side face, and all the more easily that said end 32 is disposed just upstream of a roller or a brush 35 for plating the section against the face of the packaging.
- the sensor 23 detects the passage of the packaging and causes the power to the motor 20 and the movement of the belts 12 and 13 over a length corresponding to the length of the section. The section, still linked to the strip 10, is therefore applied by the roller 35 against the face of the packaging.
- the drive effort communicated in packaging 3 and in section 32 causes the line of tear to be torn pre-cutting 30, so that the cut section leaves with the packaging, while the end 32 of the following section is placed in the standby position and, projecting, in the trajectory of the following conditioning.
- the tape stop triggers the operation of the means performing the precut 30.
- the strands 12a and 13a Compared to current distribution systems, it has a safe operation, because the movement of the strands 12a and 13a, at the end of the journey straight, is carried out by a clearance towards the outside, from the edges longitudinal of the section, and in the opposite direction, without communicating with the section 33 any effort tending to deviate from the path imposed on it.
- the strands protect the adhesive side and prevent that, when stopped or when its movement, it sticks to a surface of the device generating a distribution incident.
- the length of the strands 12a, 13a of the two belts 12 and 13 is determined so that, by adjusting the position of the means of realization of the precut 30, the same distribution device can be used to distribute sections of different lengths.
- the belts 12 and 13 are replaced by endless chains against the side faces of which the adhesive tape is plated.
- the return strands may, depending on congestion, describe various trajectories passing over more than one return pulley 16 or 17.
- the entire device which has been described in the case of its application to the distribution of sections of adhesive tape on the side of a packaging, can also put adhesive sections on top of a packaging or a batch of packaging, by changing its position by relation to the packaging trajectory.
- the means carrying out the precut 30 are arranged outside of the drive means A and B, in upstream or downstream of these means.
- This device for moving the adhesive tape can also be implemented with means cutting the section downstream of the means A and B.
- the device is similar to that shown in Figures 1 and 2, except for the sectioning means which can be of the same type as those shown in Figure 3, with a blade straight of length at least equal to the width of the strip and moved when when the tape stops, or be rotatable and operate before the tape stops Of the band.
- the tape moving device has been described in its application to a device for dispensing adhesive sections, its application is not limited to this, since it can be used to distribute an adhesive strip between two stations performing various operations on the tape, such as labeling, printing, decoration.

Abstract
Description
L'invention est relative à un dispositif de déplacement d'une bande adhésive, par exemple pour un appareil de distribution de tronçons adhésifs sur des conditionnements.The invention relates to a device for moving a strip adhesive, for example for a device for dispensing adhesive sections on packaging.
Dans la présente description, l'expression « tronçon de bande adhésive» désigne une étiquette adhésive, une bande adhésive réunissant plusieurs composants d'un lot ou une bande d'information s'étendant sur le côté ou sur le dessus d'un lot ou d'un article.In the present description, the expression “strip section adhesive "means an adhesive label, an adhesive strip joining multiple components of a batch or an information strip spanning the side or top of a lot or item.
Avant de distribuer un tronçon de bande adhésive, il faut d'abord dévider une bobine de bande adhésive et l'acheminer à un poste de découpage ou de prédécoupage. En général, en raison du caractère adhésif de l'une des faces de la bande, l'acheminement est assuré par contact de rouleaux contre le dos non adhésif de la bande mise en tension. Quels que soient les moyens mis en oeuvre pour dévider la bobine et déplacer la bande, il arrive fréquemment des incidents de distribution en raison du caractère adhésif de la bande ou des tronçons.Before dispensing a section of adhesive tape, you must first unwind a reel of adhesive tape and send it to a post cutting or precut. In general, due to the adhesive nature of one of the faces of the strip, the routing is ensured by contact of rollers against the non-adhesive back of the tensioned strip. Some the means used to unwind the reel and move the strip, it distribution incidents occur frequently due to the adhesive nature of the strip or sections.
Le document EP-A-921 073 au nom de la déposante est relatif à un dispositif comprenant des moyens de dévidage d'une bobine de bande adhésive, des moyens réalisant une prédécoupe transversale dans la bande, un rouleau ou une brosse de plaquage de la bande sur l'une des faces longitudinales de chaque conditionnement en défilement, et des moyens provoquant la rupture de la ligne de prédécoupe par une différence de vitesse instantanée, respectivement de la bande et du tronçon de bande.Document EP-A-921 073 in the name of the applicant relates to a device comprising means for unwinding a reel of tape adhesive, means carrying out a transverse precut in the strip, a roller or a brush for plating the strip on one of the faces longitudinal of each scrolling packaging, and means causing a break in the precut line by a difference in speed instant, respectively of the strip and of the strip section.
Plus précisément, dans ce dispositif, la rupture de la ligne de prédécoupe est assurée par l'accélération du lot sur lequel la bande adhésive est appliquée par rapport au convoyeur amont acheminant une file de conditionnement au poste de distribution, cette accélération étant obtenue par les moyens d'entraínement aval qui entraínent le lot de conditionnement à une vitesse linéaire supérieure à celle de déplacement du convoyeur amont. En pratique, il se révèle que le différentiel de vitesse entre les convoyeurs amont et aval nécessite des réglages fins et réguliers, à défaut de quoi la rupture du tronçon ne s'effectue pas dans de parfaite condition.More precisely, in this device, the breaking of the line of pre-cutting is ensured by the acceleration of the batch on which the adhesive strip is applied relative to the upstream conveyor carrying a line of packaging at the distribution station, this acceleration being obtained by the downstream drive means which cause the packaging batch to a linear speed greater than that of movement of the upstream conveyor. In practical, it turns out that the speed differential between the upstream conveyors and downstream requires fine and regular adjustments, failing which the rupture of the section is not carried out in perfect condition.
La présente invention a pour objet de fournir un dispositif de déplacement d'une bande adhésive, utilisable entre autres pour la distribution de tronçons de bande sur des conditionnements ou articles en défilement qui remédie aux inconvénients des dispositifs actuels et, en particulier, élimine les arrêts de distribution consécutifs à des blocages par calage de la bande ou des tronçons.The object of the present invention is to provide a device for displacement of an adhesive strip, usable among other things for distribution strip sections on packaging or moving articles which remedies the disadvantages of current devices and, in particular, eliminates the distribution stops following blockages by wedging the belt or sections.
On connaít par le document EP-A-577 241, un dispositif de déplacement de tronçons d'étiquettes découpés dans une bande adhésive en bobine, dispositif comprenant des courroies de section circulaire, superposées, décrivant chacune une trajectoire sans fin et disposées dans un caisson relié au vide et leurs brins décrivent une trajectoire rectiligne dans l'ouverture du caisson, et reçoivent sur leur face extérieure les étiquettes, celles-ci étant plaquées sur les brins par leur face adhésive mais maintenues par l'aspiration du caisson. En fin de parcours, chaque étiquette est séparée des brins par des rouleaux de pelage qui, malgré leur faible surface de contact avec chaque étiquette, sont sources d'incident, par collage et accumulation sur eux des étiquettes.Document EP-A-577 241 discloses a device for moving sections of labels cut from adhesive tape coil, device comprising belts of circular section, superimposed, each describing an endless trajectory and arranged in a connected box vacuum and their strands describe a straight path in the opening of the box, and receive the labels on their outside, these being pressed on the strands by their adhesive side but held by the suction of the box. At the end of the journey, each label is separated from the strands by peeling rollers which, despite their small contact surface with each label, are sources of incident, by sticking and accumulation on them of tags.
Le document DAS 1 116 145 est relatif à un dispositif de distribution de stanioles préencollées dans la trajectoire du col de bouteille en déplacement. Après encollage et découpage, la staniole est transférée sur deux courroies espacées reliées aux mêmes moyens moteur, et plus précisément est plaquée, par ses bords longitudinaux, sur la face externe des brins verticaux espacés de deux courroies décrivant des trajectoires sans fin de part et d'autre de la trajectoire de passage des cols.The document DAS 1 116 145 relates to a device for distribution of pre-glued stanioles in the trajectory of the bottle neck in displacement. After gluing and cutting, the staniole is transferred to two spaced belts connected to the same motor means, and more precisely is pressed, by its longitudinal edges, on the external face of vertical strands spaced by two belts describing endless paths of on either side of the pass path.
Comme dans le dispositif précédent, les chants des deux courroies sont dans des plans différentes, parallèles entre eux, mais perpendiculaires à la bande.As in the previous device, the songs of the two belts are in different planes, parallel to each other, but perpendicular to the band.
Les courroies se déplacent pas à pas de manière à amener la première staniole dans la trajectoire d'un col qui la prélève au passage, avant que des brosses rabattent les côtés de cette staniole contre le col de la bouteille. Malgré le prélèvement par le col qui passe entre les deux courroies, ce dispositif n'est pas à l'abri des incidents de distribution.The belts move step by step so as to bring the first staniole in the trajectory of a pass which takes it in passing, before brushes fold the sides of this staniole against the neck of the bottle. Despite the removal by the collar which passes between the two belts, this system is not immune to distribution incidents.
La présente invention met en oeuvre ces moyens d'entraínement en les organisant différemment.The present invention implements these drive means in organizing them differently.
A cet effet, dans le dispositif de déplacement d'une bande adhésive selon l'invention, les deux moyens d'entraínement sont disposés de manière que le brin actif qui, dans chacun d'eux, coopère avec la face adhésive de la bande, soit rectiligne, parallèle, espacé du brin actif juxtaposé de l'autre moyen d'entraínement, et possède un chant disposé sensiblement dans le même plan que celui du brin actif du moyen d'entraínement juxtaposé, ce plan étant parallèle et confondu avec celui de la bande, ces deux brins actifs en vis-à-vis étant espacés l'un de l'autre par une distance inférieure à la largeur de la bande adhésive afin que leurs chants coopèrent avec les bords longitudinaux de ladite bande.To this end, in the device for moving a strip adhesive according to the invention, the two drive means are arranged so that the active strand which, in each of them, cooperates with the face tape adhesive, either straight, parallel, spaced from active strand juxtaposed with the other drive means, and has a song arranged substantially in the same plane as that of the active strand of the means juxtaposed drive, this plane being parallel and coincident with that of the strip, these two active strands facing each other being spaced from each other by a distance less than the width of the adhesive strip so that their edges cooperate with the longitudinal edges of said strip.
Avec ce dispositif, la bande adhésive est déplacée uniquement par son collage temporaire sur les brins des deux moyens d'entraínement. De ce fait, la face adhésive est protégée durant son déplacement et ne risque pas de se coller sur une surface du dispositif, en générant des incidents de distribution. La disposition des moyens d'entraínement avec les courroies sensiblement dans le même plan et de part et d'autre de la bande en défilement permet aux brins de se séparer de la face adhésive en générant deux efforts opposés qui, perpendiculaires aux bords longitudinaux de la bande, s'annulent et n'influencent pas la trajectoire de sortie de la bande.With this device, the adhesive tape is moved only by its temporary bonding on the strands of the two drive means. From this done, the adhesive side is protected during its movement and does not risk stick to a surface of the device, generating incidents of distribution. The provision of drive means with belts substantially in the same plane and on either side of the strip in scrolling allows the strands to separate from the adhesive side by generating two opposite forces which, perpendicular to the longitudinal edges of the tape, cancel each other and do not influence the tape exit trajectory.
Dans une forme d'exécution et pour la distribution de tronçons adhésifs prédécoupés, les moyens d'entraínement sans fin sont disposés de manière que la trajectoire de déplacement de la bande amène l'extrémité libre d'un tronçon extrême dans la trajectoire de conditionnements en déplacement sur un convoyeur, en amont d'un rouleau ou d'une brosse de plaquage, et le moteur électrique, commun aux moyens d'entraínement, est contrôlé par un moyen de commande déclenchant son alimentation au passage de chaque conditionnement et arrêtant son alimentation quand une longueur de tronçon est dévidée et est au moins partiellement plaquée contre le conditionnement, pour provoquer, par arrêt du dévidage, la déchirure d'une ligne de prédécoupage formée entre la bande et son tronçon extrême.In one embodiment and for the distribution of sections pre-cut adhesives, the endless drive means are arranged so that the tape movement path brings the free end of an extreme section in the path of packaging in displacement on a conveyor, upstream of a plating roller or brush, and the electric motor, common to the drive means, is controlled by a control means triggering its supply at the passage of each conditioning and stopping its feeding when a section length is unwound and is at least partially pressed against the packaging, to cause, by stopping the unwinding, the tearing of a line of precut formed between the strip and its extreme section.
En position d'attente, l'extrémité libre du tronçon extrême prédécoupé dans la bande est en saillie des moyens d'entraínement et est disposée dans la trajectoire de déplacement du conditionnement devant recevoir ce tronçon et en amont de la brosse ou du rouleau de plaquage. Dans ces conditions, lorsque le conditionnement en déplacement rencontre l'extrémité du tronçon, la face adhésive de celui-ci se colle sur le conditionnement, tandis que, simultanément les moyens d'entraínement du dispositif de distribution sont alimentés pour débiter une longueur de bande correspondant à la longueur d'un tronçon. Dès que cette longueur de bande est débitée, les moyens d'entraínement sont arrêtés afin que l'effort de déplacement communiqué par le conditionnement au tronçon de bande collé sur lui provoque la rupture de la ligne de prédécoupage entre le tronçon et la bande adhésive. Par le mouvement du convoyeur, le tronçon est plaqué par la brosse ou le rouleau sur la face correspondante du conditionnement, tandis que l'extrémité du tronçon suivant fait saillie dans la trajectoire de déplacement des conditionnements. Ce dispositif fonctionne au coup par coup, quel que soit l'intervalle entre deux conditionnements successifs.In the standby position, the free end of the extreme section pre-cut in the strip protrudes from the drive means and is arranged in the path of movement of the packaging in front receive this section and upstream of the brush or the plating roller. In these conditions, when the packaging on the move meets the end of the section, the adhesive side of it sticks to the conditioning, while simultaneously the means of driving the dispensing device are powered to deliver a length of tape corresponding to the length of a section. As soon as this strip length is charged, the drive means are stopped so that the effort of displacement communicated by the packaging to the glued strip section on it causes the pre-cutting line between the section and the band-Aid. By the movement of the conveyor, the section is pressed by the brush or roller on the corresponding side of the packaging, while that the end of the next section protrudes in the displacement path packaging. This device works piecemeal, whatever the interval between two successive packages.
Avantageusement, les moyens de prédécoupage du tronçon dans la bande sont constitués, d'une part, par une lame disposée transversalement entre les deux brins actifs des moyens de dévidage, cette lame étant reliée à des moyens aptes à la déplacer alternativement dans un sens en direction de la bande, puis dans l'autre sens, sous le contrôle de moyens de commande réagissant à l'arrêt du dévidage, et, d'autre part, par une enclume fixe contre laquelle glisse le dos non adhésif de la bande.Advantageously, the means for precutting the section in the strip are formed, on the one hand, by a blade arranged transversely between the two active strands of the unwinding means, this blade being connected to means able to move it alternately in one direction towards the strip, then in the other direction, under the control of control means reacting to the stopping of the reeling, and, on the other hand, by a fixed anvil against which slides the non-adhesive back of the strip.
Cet aménagement simple permet de réaliser la prédécoupe à l'arrêt de défilement et dans d'excellentes conditions, sans augmenter l'encombrement général du dispositif.This simple arrangement makes it possible to carry out the precut when stationary scrolling and in excellent conditions, without increasing the overall size of the device.
D'autres caractéristiques et avantages ressortiront de la description
qui suit en référence au dessin schématique annexé représentant, à titre
d'exemple, une forme d'exécution du dispositif selon l'invention dans le cas de
son application à une installation de distribution de tronçons prédécoupés.
Aux figures 1 et 2, la référence numérique 2 désigne le plan de
déplacement d'un convoyeur à rouleaux sur lequel des conditionnements 3
sont déplacés par des moyens d'entraínement, et par exemple, par les brins
espacés 4a, 5a de courroies d'entraínement 4 et 5 circulant entre une poulie
motrice 6 et une poulie de renvoi 7 et se déplaçant dans le sens de la flèche 8
à la figure 2. 9 désigne une bobine de bande adhésive 10 dont la face 10a
porte l'adhésif. In Figures 1 and 2, the reference numeral 2 denotes the plane of
displacement of a roller conveyor on which
Dans la forme d'exécution représentée, les moyens de
déplacement de la bande adhésive assurent le dévidage de la bobine 9 et
comprennent deux moyens d'entraínement espacés A et B composés chacun
d'une courroie 12, 13 circulant entre une roue de renvoi motrice 14, 15 et une
roue de renvoi libre 16, 17, en décrivant des trajectoires dans le plan vertical,
parallèlement à la bande devant être déplacée. Les deux brins 12a, 13a, qui
sont en vis à vis, sont rectilignes, parallèles et espacés par une distance
inférieure à la largeur de la bande 10, et sont disposés de manière que leur
chant 12b, 13b, faisant vis-à-vis à la bande, soit dans le même plan que celui
de l'autre courroie, ce plan étant parallèle à la bande, afin que, par plaquage au
moyen d'un rouleau 18 d'axe vertical, les bords longitudinaux adhésifs de la
bande 10 se collent temporairement contre ces chants longitudinaux12b, 13b.In the embodiment shown, the means of
displacement of the adhesive tape ensure the unwinding of the reel 9 and
include two spaced drive means A and B each composed
a
Les roues motrices 14 et 15 sont reliées par un mécanisme à
engrenages 19 à un moteur électrique commun 20 qui est apte à
communiquer, aux courroies 12 et 13, un mouvement de déplacement, dans le
sens des flèches 21 et à une vitesse égale à la vitesse de déplacement des
conditionnements 3. Ce moteur, de type pas à pas ou brushless, est
commandé par un boítier de commande 22 qui réagit aux sollicitations d'un
capteur 23, visible figure 2, détectant le passage de chaque conditionnement 3
et auquel il est relié par un circuit 24.The
Le dispositif comprend des moyens réalisant une prédécoupe dans
la bande 10 dévidée, moyens qui, dans la forme d'exécution représentée et
comme montré plus en détails à la figure 3, sont composés d'une lame dentée
26 et d'une enclume 27, disposées de part et d'autre de la trajectoire de
déplacement de la bande 10. La lame 26 est disposée entre les deux brins
12a, 13a des moyens d'entraínement A, B et est portée par un support 28, lui-même
relié à des moyens 29, aptes à déplacer alternativement la lame entre
une position de repos, montrée à la figure 3, et une position de travail dans
laquelle elle vient en contact de la bande 10, alors en appui sur l'enclume 27.
Dans cette position, la lame réalise une ligne de prédécoupage transversale 30
s'étendant sur la plus grande partie de la largeur de la bande adhésive 10, à
l'exception des zones extrêmes Z, montrées à la figure 4, correspondant aux
bords longitudinaux de la bande adhérant contre les chants 12b, 13b des
courroies 12 et 13. Les moyens moteurs 29 peuvent être constitués par un
vérin pneumatique, par un vérin électrique ou par un électro-aimant.
L'ensemble, composé de la lame 26 avec son support 28 et ses moyens
moteurs 29, mais aussi avec l'enclume 27, est porté par un support non
représenté, pouvant être déplacé longitudinalement par rapport au châssis
portant l'ensemble du dispositif de distribution, de manière à pouvoir régler la
position de la ligne de prédécoupage 30 par rapport à l'extrémité libre 32 du
tronçon prédécoupé 33.The device comprises means carrying out a precut in
the
La lame 26 peut aussi posséder un tranchant rectiligne réalisant
une découpe franche mais constituant un prédécoupage en raison des zones Z
non découpées.The
Les figures 1 et 2 montrent que le châssis 31, portant les deux
moyens d'entraínement A et B, le rouleau 18 et les moyens de prédécoupage
26 à 29, est disposé latéralement à la trajectoire de déplacement des
conditionnements 3 représentée par la flèche 8 à la figure 2 et en formant, par
rapport à cette trajectoire, un angle a qui, dans la forme d'exécution
représentée, est aigu, mais peut également être droit, si l'environnement le
permet.Figures 1 and 2 show that the frame 31, carrying the two drive means A and B, the
Le boítier de commande 22, régissant l'alimentation du moteur
électrique pas à pas 20, est conçu pour arrêter l'alimentation de ce moteur
lorsque l'extrémité libre 32 du tronçon 33 débordant des extrémités aval des
moyens d'entraínement A et B vient dans la trajectoire de déplacement des
conditionnements 3, c'est-à-dire occupe la position montrée à la figure 1.The
Dans ces conditions, lorsqu'un conditionnement en déplacement
par les moyens de convoyage 4, 5 rencontre l'extrémité libre 32 du tronçon 33,
la face adhésive de ce tronçon se, colle sur l'extrémité du conditionnement, et
en l'occurrence contre sa face longitudinale latérale, et cela d'autant plus
facilement que ladite extrémité 32 est disposée juste en amont d'un rouleau ou
d'une brosse 35 de plaquage du tronçon contre la face du conditionnement.
Simultanément, le capteur 23 détecte le passage du conditionnement et
provoque l'alimentation du moteur 20 et la mise en mouvement des courroies
12 et 13 sur une longueur correspondante à la longueur du tronçon. Le
tronçon, toujours lié à la bande 10, est donc appliqué par le rouleau 35 contre
la face du conditionnement.Under these conditions, when packaging on the go
by the conveying means 4, 5 meets the
Dès que le moteur 20 s'arrête, l'effort d'entraínement communiqué
au conditionnement 3 et au tronçon 32 provoque la déchirure de la ligne de
prédécoupage 30, de sorte que le tronçon débité part avec le conditionnement,
tandis que l'extrémité 32 du tronçon suivant est disposée en position d'attente
et, en saillie, dans la trajectoire du conditionnement suivant. L'arrêt de la bande
déclenche le fonctionnement des moyens réalisant la prédécoupe 30.As soon as the
Il ressort de ce qui précède que le dispositif fonctionne automatiquement au passage de chaque conditionnement, indépendamment de l'intervalle entre deux conditionnements.It appears from the above that the device works automatically when each package passes, independently the interval between two packages.
Par rapport aux dispositifs de distribution actuels, il a un
fonctionnement sûr, car le mouvement des brins 12a et 13a, en fin de parcours
rectiligne, s'effectue par un dégagement vers l'extérieur, à partir des bords
longitudinaux du tronçon, et en sens inverse, sans communiquer au tronçon 33
un quelconque effort tendant à le dévier de la trajectoire qui lui est imposée. De
plus, les brins protégent la face adhésive et empêchent que, à l'arrêt ou lors de
son déplacement, elle se colle sur une surface du dispositif en générant un
incident de distribution.Compared to current distribution systems, it has a
safe operation, because the movement of the
La longueur des brins 12a, 13a des deux courroies 12 et 13 est
déterminée de manière que, par réglage de la position des moyens de
réalisation de la prédécoupe 30, le même dispositif de distribution puisse être
utilisé pour distribuer des tronçons de longueurs différentes.The length of the
Dans une variante de réalisation, les courroies 12 et 13 sont
remplacées par des chaínes sans fin contre les faces latérales desquelles la
bande adhésive est plaquée.In an alternative embodiment, the
S'il est indispensable que les brins 12a, 13a décrivent des
trajectoires rectilignes parallèles, les brins de retour peuvent, en fonction de
l'encombrement, décrire des trajectoires diverses en passant sur plus d'une
poulie de renvoi 16 ou 17.If it is essential that the
L'ensemble du dispositif, qui a été décrit dans le cas de son application à la distribution de tronçons de bande adhésive sur le côté d'un conditionnement, peut aussi poser des tronçons adhésifs sur le dessus d'un conditionnement ou d'un lot de conditionnements, en modifiant sa position par rapport à la trajectoire des conditionnements.The entire device, which has been described in the case of its application to the distribution of sections of adhesive tape on the side of a packaging, can also put adhesive sections on top of a packaging or a batch of packaging, by changing its position by relation to the packaging trajectory.
Dans une variante non représentée, les moyens réalisant la prédécoupe 30 sont disposés hors des moyens d'entraínement A et B, en amont ou en aval de ces moyens.In a variant not shown, the means carrying out the precut 30 are arranged outside of the drive means A and B, in upstream or downstream of these means.
Ce dispositif de déplacement de la bande adhésive peut aussi être mis en oeuvre avec des moyens découpant le tronçon en aval des moyens d'entraínement A et B. Dans ce cas, le dispositif est similaire à celui représentée aux figures 1 et 2, à l'exception des moyens de sectionnement qui peuvent être du même type que ceux représentés figure 3, avec une lame rectiligne de longueur au moins égale à la largeur de la bande et déplacée lors de l'arrêt de la bande, ou être rotatifs et fonctionner avant l'arrêt de défilement de la bande.This device for moving the adhesive tape can also be implemented with means cutting the section downstream of the means A and B. In this case, the device is similar to that shown in Figures 1 and 2, except for the sectioning means which can be of the same type as those shown in Figure 3, with a blade straight of length at least equal to the width of the strip and moved when when the tape stops, or be rotatable and operate before the tape stops Of the band.
Bien que le dispositif de déplacement d'une bande adhésive ait été décrit dans son application à un appareil de distribution de tronçons adhésifs, son application n'est pas limitée à cela, puisqu'il peut être utilisé pour distribuer une bande adhésive entre deux postes réalisant diverses opérations sur la bande, telles que pose d'étiquettes, impression, décoration.Although the tape moving device has been described in its application to a device for dispensing adhesive sections, its application is not limited to this, since it can be used to distribute an adhesive strip between two stations performing various operations on the tape, such as labeling, printing, decoration.
De même, le dispositif à été décrit dans le cas d'une application fonctionnant avec avancement pas à pas et arrêt de la bande adhésive, mais il peut aussi être appliqué sur une installation fonctionnant en continu et distribuant en permanence de la bande adhésive ou des tronçons de bande sectionnés au défilement, par exemple par un couteau rotatif.Similarly, the device has been described in the case of an application working with step-by-step advancement and tape stop, but it can also be applied to a continuously operating installation and continuously dispensing adhesive tape or strip of tape sectioned by scrolling, for example by a rotary knife.
