L'objet de l'invention se rattache notamment aux secteurs techniques de la manipulation des matériaux en bandes et du traitement des textiles après fabrication.The object of the invention relates in particular to the technical sectors of the handling of strip materials and the treatment of textiles after manufacture.
Suivant l'invention, on a voulu réaliser une machine qui, successivement et dans une action continue, assure le déroulement des bandes à partir de mateaux, la rétraction des bandes déroulées, le séchage des bandes rétractées, et le bobinage en longueurs déterminées avec contrôle de la qualité et des éventuelles variations de longueurs.According to the invention, we wanted to make a machine which, successively and in a continuous action, ensures the unrolling of the strips from fabrics, the retraction of the unrolled strips, the drying of the retracted strips, and the winding in determined lengths with control quality and possible length variations.
Pour cela, la machine selon l'invention est esentielle- ment composée d'une succession de postes selon lesquels, les bandes stockées sur des mateaux, sont déroulées en tension constante par des coupleurs électromagnétiques associés aux moteurs d'entraînement et avec accrochages en continu des bandes de mateaux différents, puis amenées, soit à un moyen de rétraction par vaporisation sous tension réduite, par l'intermédiaire d'au moins un dispositif donneur ou magasin ; soit directement à une enceinte de séchage et de rétraction, puis les bandes séchées traversent une réserve variable de bandes par enroulements alternés, avant d'être bobinées en longueurs déterminées avec contrôle permanent de la qualité, contrôle et règlage permanents des longueurs, et moyens d'enroulement des bandes et d'éjection des bobines constituées ; tous ces postes travaillant en synchronisme sous la conduite d'un moyen de commande du type automate programmable.For this, the machine according to the invention is essentially composed of a succession of stations according to which, the strips stored on the mat, are unwound at constant voltage by electromagnetic couplers associated with the drive motors and with continuous latching strips of different materials, then brought either to a means of shrinking by vaporization under reduced tension, by means of at least one donor or store device; either directly to a drying and shrinking enclosure, then the dried strips pass through a variable reserve of strips by alternating windings, before being wound up in determined lengths with permanent quality control, permanent control and adjustment of the lengths, and means of 'winding of the strips and ejection of the coils formed; all these stations working in synchronism under the control of a control means of the programmable automaton type.

Comme on le voit bien aux figures 1 et 2, la machine selon l'invention comprend dans l'exemple non limitatif illustré, deux postes d'alimentation (Al - A2), un poste de rétraction (B), un poste de séchage (C) et un poste de bobinage (D) séparé du poste (C) par un dispositif de réserve variable de bande (E).As can be seen in Figures 1 and 2, the machine according to the invention comprises in the nonlimiting example illustrated, two supply stations (Al - A2), a retraction station (B), a drying station (C) and a winding station (D) separated from the station (C) by a variable tape reserve device (E).
On a prévu deux postes d'alimentation (Al - A2) pour délivrer simultanément deux bandes accolées (bl - b2) au poste de rétraction. Pour cela, comme illustré à la figure 2, on décale transversalement les mateaux (1 S 2) montés sur le poste (Al) par rapport aux mateaux (3 - 4) montés sur le poste (A2). Bien entendu, on pourrait prévoir un seul poste d'alimentation délivrant une bande de largeur double, ou encore plus de deux bandes en adaptant s'il y a lieu, la largeur des différents postes pour le passage des bandes.Two feeding stations (Al - A2) are provided for simultaneously delivering two adjoining strips (bl - b2) to the retraction station. For this, as illustrated in FIG. 2, the mats (1 S 2) mounted on the station (Al) are transversely offset with respect to the mats (3 - 4) mounted on the station (A2). Of course, one could provide a single supply station delivering a strip of double width, or even more than two strips by adapting if necessary, the width of the different stations for the passage of the strips.
En se référant plus particulièrement aux figures 1, 2, 3, 8, 9 et 10, on décrit maintenant les postes d'alimentation (Al - A2), dans le détail.Referring more particularly to FIGS. 1, 2, 3, 8, 9 and 10, the supply stations (A1 - A2) will now be described in detail.
Chaque poste est formé d'un bâti mécanosoudé comprenant une structure porteuse arrière (5 - 6) pour le montage des mateaux et une structure porteuse avant (7 - 8) pour le dispositif donneur ou magasin (F - G). Ces deux structures peuvent être solidaires ou indépendantes. Chaque mateau est porté à rotation libre par un axe-support (9) relié à un dispositif de freinage du type coupleur électromagnétique à poudre (10) pour assurer un déroulement en tension consolante entre le mateau et son moteur d'entraînement (11) représenté schématiquement en bout de l'axe-support à la figure 2.Each station consists of a mechanically welded frame comprising a rear support structure (5 - 6) for mounting the mat and a front support structure (7 - 8) for the donor or store device (F - G). These two structures can be integral or independent. Each mat is carried in free rotation by a support pin (9) connected to a braking device of the electromagnetic powder coupler type (10) to ensure a constant tension unwinding between the mat and its drive motor (11) shown schematically at the end of the support axis in Figure 2.
Les bandes (bl - b2) enroulées sur les mateaux (2 et 4) sont développées successivement sur des rouleaux d'alignement intérieurs (12) et sur des rouleaux d'alignement supérieurs (13) portés à rotation libre par des potences mécanosoudées (14-15) qui sont reliées aux structures porteuses (7 - 8). Puis les dites bandes traversent le dispositif donneur qui comprend essentiellement un chariot (16) constitué par deux flasques triangulaires (16a), reliés axialement entre eux par un tambour (16b) monté à rotation libre sur les flasques, par des roulements (16c) ou organes similaires.The bands (bl - b2) wound on the mat (2 and 4) are developed successively on internal alignment rollers (12) and on upper alignment rollers (13) carried in free rotation by mechanically welded brackets (14 -15) which are connected to the supporting structures (7 - 8). Then said bands pass through the donor device which essentially comprises a carriage (16) constituted by two triangular flanges (16a), connected axially to each other by a drum (16b) mounted for free rotation on the flanges, by bearings (16c) or similar organs.
A chaque sommet, les flasques portent à rotation libre par roulements (16d) ou équivalents, des pignons (16e). Comme on le voit mieux aux figures 3 et 8, les flasques (16a) sont orientés de telle sorte que pour chaque flasque deux pignons engrènent simultanément avec des crémaillères (17) portées par les montants arrière (7a ou 8a) de la structure avant (7 ou 8), tandis que les troisièmes pignons engrènent avec des crémaillères opposées (18) portées par des montants avant (7b ou 8b). A noter que pour assurer un roulement correct du chariot par les pignons et les crémaillères, ces dernières sont montées sur les montants par l'intermédiaire de profilés en équerre (19) règlables par rapport à ces montants.At each vertex, the flanges carry free rotation by bearings (16d) or the equivalent, pinions (16th). As best seen in Figures 3 and 8, the flanges (16a) are oriented so that for each flange two pinions mesh simultaneously with racks (17) carried by the rear uprights (7a or 8a) of the front structure (7 or 8), while the third pinions mesh with opposite racks (18) carried by front uprights (7b or 8b). Note that to ensure correct rolling of the carriage by the pinions and the racks, the latter are mounted on the uprights by means of angle profiles (19) adjustable relative to these uprights.
Les bandes (bl - b2) venant du ou des rouleaux supérieurs (13) sont enroulées sur le tambour (16b) du chariot, après être passées par un rouleau de renvoi (20): Après leur enroulement sur le tambour (16b), les bandes (bl - b2) remontent s'enrouler sur un autre rouleau de renvoi (21) et sont dirigées vers le poste de rétraction. Les rouleaux (20 - 21) sont respectivement portés à rotation libre en haut des montants avant et arrière (7a - 7b) ou (8a - 8b) .The strips (bl - b2) coming from the upper roller (s) (13) are wound on the drum (16b) of the carriage, after having passed through a deflection roller (20): After their winding on the drum (16b), the bands (bl - b2) go up to be wound on another deflection roller (21) and are directed towards the retraction station. The rollers (20 - 21) are respectively rotated freely at the top of the front and rear uprights (7a - 7b) or (8a - 8b).
On comprend que, lorsqu'un appel de bande devient plus important en aval ou lorsque le freinage des mateaux est plus important, le chariot monte dans le magasin en réduisant la boucle emmagasinée. Inversement, lorsqu'il y a réduction de freinage ou d'appel, le chariot descend dans le magasin en allongeant la boucle. A noter que l'action de freinage ou de dé- freinage des coupleurs est commandée par un potentiomètre agissant en fonction de la position du chariot.It is understood that, when a band call becomes more important downstream or when the braking of the fabrics is more important, the carriage goes up into the store by reducing the stored loop. Conversely, when there is a reduction in braking or call, the carriage descends into the store by lengthening the loop. Note that the braking or braking action of the couplers is controlled by a potentiometer acting according to the position of the carriage.
Les bandes (bl - b2) passent ensuite dans le poste de rétraction qui a pour but de les rendre extensibles ou d'augmenter leur capacité élastique. A cet effet, les bandes passent entre un rouleau moteur (22) et un galet presseur (23) porté par des bras (24) articulés en (25) sur des montants du bâti (26), avec ressorts (27) de rappel élastique. Le rouleau (22) est relié à un ensemble moteur-réducteur à vitesse variable (28) d' entraînement des bandes qui traversent ensuite horizontalement une enceinte isolante (29) équipée de buses (30) distribuant de la vapeur d'eau sans pression notable (figure 4).The bands (bl - b2) then pass into the retraction station which aims to make them extensible or to increase their elastic capacity. To this end, the bands pass between a drive roller (22) and a pressure roller (23) carried by arms (24) articulated at (25) on the uprights of the frame (26), with springs (27) of elastic return . The roller (22) is connected to a variable speed motor-reducer assembly (28) for driving the bands which then pass horizontally through an insulating enclosure (29) equipped with nozzles (30) distributing water vapor without significant pressure (figure 4).
L'enceinte (29) est formée d'un couvercle (29a) en double pente et d'une base (29b) de forme générale en U. Les deux parties de l'enceinte entre lesquelles passent les bandes sont constituées par une enveloppe enfermant un matériau isolant (31), et des goulottes (29c) recueillent les gouttes de condensation (figure 5) en dehors du cheminement des bandes.The enclosure (29) is formed of a cover (29a) in double slope and of a base (29b) of general U-shape. The two parts of the enclosure between which the strips pass are constituted by an envelope enclosing an insulating material (31), and troughs (29c) collect the drops of condensation (Figure 5) outside the path of the strips.
A noter encore que les bandes sont guidées dans la traversée de l'enceinte de vaporisation par glissement sur des axes-supports (32) disposés à intervalles réguliers et qui sont montés très libres en rotation, afin de ne pas modifier les conditions de rétraction des bandes (figure-4).Note also that the strips are guided through the vaporization enclosure by sliding on support pins (32) arranged at regular intervals and which are mounted very freely in rotation, so as not to modify the conditions of retraction of the bands (figure-4).
A la sortie de l'enceinte, les bandes rétractées s'enroulent sur un rouleau de renvoi fixe (33) et autour d'un rouleau moteur (34) associé à un ensemble moteur-réducteur à vitesse variable (35), destiné à compenser l'écart de longueur des bandes entre l'entrée et la sortie du poste de rétraction.At the exit of the enclosure, the retracted bands are wound on a fixed deflection roller (33) and around a motor roller (34) associated with a variable speed motor-reducer assembly (35), intended to compensate the difference in length of the strips between the inlet and the outlet of the shrinking station.
Les bandes (bl - b2) traversent ensuite le poste (C) de séchage pour supprimer l'humidité due à la vaporisation et pour parfaire la rétraction. Pour cela, les bandes passent sous un four ou une enceinte isolante (36) portée par un bâti (37) et équipée de lampes à infra-rouges (38) ou autres moyens similaires (figures 6 et 7).The strips (bl - b2) then pass through the drying station (C) to remove the humidity due to vaporization and to perfect the retraction. For this, the strips pass under an oven or an insulating enclosure (36) carried by a frame (37) and equipped with infrared lamps (38) or other similar means (Figures 6 and 7).
Les bandes (bl - b2) séchées sont alors acheminées vers le poste de bobinage (D) en passant au préalable par le dispositif de réserve variable (E), et éventuellement par un troisième ensemble moteur-réducteur d'entraînement, disposé en sortie du four.The dried strips (bl - b2) are then conveyed to the winding station (D) passing beforehand by the variable reserve device (E), and possibly by a third motor-reducer drive assembly, disposed at the outlet of the oven.
Le dispositif de réserve variable de bande (E) illustré aux figures 1, 2, 11 et 12, comprend un bâti (39) dont les quatre montants (39a) reçoivent une crémaillère (40) à positionnement réglable par des profilés en équerre (41). Un chariot (42) composé de deux flasques (42a) de forme générale en T et entretoisés en (42b), présente suivant les extrémités des trois branches du T, des pignons (43) portés par des axes-supports (44), afin d'engrèner avec les crémaillères selon la disposition illustrée figure 1.The variable band reserve device (E) illustrated in FIGS. 1, 2, 11 and 12, comprises a frame (39) whose four uprights (39a) receive a rack (40) with adjustable positioning by angle profiles (41 ). A carriage (42) composed of two flanges (42a) of general shape in T and braced in (42b), has, according to the ends of the three branches of the T, pinions (43) carried by support axes (44), so to mesh with the racks according to the arrangement illustrated in Figure 1.
En haut des montants (39a) sont montés à rotation libre par pointes de centrage à billes (45), des rouleaux de renvoi (46), tandis que d'autres rouleaux de renvoi (47) sont montés également à rotation libre dans la partie médiane des flasques (42a). Dans l'exemple illustré, il y a trois rouleaux supérieurs (46) et deux rouleaux inférieurs (47), étant entendu que ce nombre pourrait être différent.At the top of the uprights (39a) are mounted with free rotation by ball centering pins (45), deflection rollers (46), while other deflection rollers (47) are also mounted with free rotation in the part median of the flanges (42a). In the example shown, there are three rollers laughers (46) and two lower rollers (47), it being understood that this number could be different.
Les bandes (bl - b2) sortant du four (36) passent sur un rouleau de renvoi (48) porté par les montants (39a) arrière, puis s'enroulent successivement sur les rouleaux supérieurs (46) et les rouleaux inférieurs (47) avant d'être acheminés au poste de bobinage (D).The strips (bl - b2) leaving the oven (36) pass on a deflection roller (48) carried by the rear uprights (39a), then wind successively on the upper rollers (46) and the lower rollers (47) before being routed to the winding station (D).
Ces enroulements alternés sont destinés à absorber de grandes longueurs de bande et assurent la continuité de défilement pendant que s'effectuent la coupe des bandes et le bobinage.These alternating windings are intended to absorb long lengths of strip and ensure continuous running while the strips are being cut and wound.
Afin d'alléger le chariot (42) et éviter une déformation ou une cassure des bandes, on prévoit des contre-poids (49) convenablement tarés et reliés par lien souple (49a) et poulies (49b) aux flasques du chariot.In order to lighten the carriage (42) and avoid deformation or breakage of the bands, counterweights (49) are suitably tared and connected by flexible link (49a) and pulleys (49b) to the flanges of the carriage.
Bien entendu, le chariot (42) présente un asservissement commandant la vitesse de l'ensemble moteur-réducteur (35) pour la ralentir si le chariot descend, ou l'accélérer si le chariot monte, cela pour compenser les avances ou les retards détectés en aval, c'est-à-dire au niveau du conditionnement des bandes bobinées.Of course, the carriage (42) has a control controlling the speed of the motor-reduction unit (35) to slow it down if the carriage descends, or to accelerate it if the carriage ascends, this to compensate for the advances or delays detected. downstream, that is to say at the level of the conditioning of the wound strips.
Avant d'être introduites dans le poste de bobinage (D), les bandes (bl - b2) passent sous une caméra (50), avec éclairage (51) sous ces bandes, chargée de contrôler leur qualité (avec mise en mémoire de l'endroit du défaut) et de détecter les rajoutures de bandes, en vue de les éliminer au bobinage, comme on le verra plus loin.Before being introduced into the winding station (D), the bands (bl - b2) pass under a camera (50), with lighting (51) under these bands, responsible for controlling their quality (with storage of the 'location of the defect) and to detect the additions of bands, with a view to eliminating them by winding, as will be seen below.
Après leur passage sous la caméra, les bandes (bl - b2) sont dirigées par un rouleau d'entrée (52) porté par une potence (53a) du bâti général (53) constituant le poste (D), vers les moyens de bobinage proprement dits (figures 13 et 14).After passing under the camera, the strips (bl - b2) are directed by an input roller (52) carried by a bracket (53a) of the general frame (53) constituting the station (D), towards the winding means proper (Figures 13 and 14).
A cet effet, les extrémités des bandes sont engagées au départ, entre des axes espacés (54) qui sont portés en bout d' une broche (55) associée à un moteur-variateur-frein (56).To this end, the ends of the bands are engaged at the start, between spaced axes (54) which are carried at the end of a spindle (55) associated with a motor-variator-brake (56).
Une autre broche (57) portant deux axes espacés (58), est également reliée à un moteur-variateur-frein (59). Ces deux organes moteurs sont portés de manière diamétralement opposée, par un flasque (60) lié à un axe central (61) tournant dans un fourreau (62) solidaire du bâti et relié par un accouplement (63) à un vérin rotatif (64) assurant les rotations du flasque suivant un demi-tour.Another spindle (57) carrying two spaced axes (58) is also connected to a motor-variator-brake (59). These two drive members are carried diametrically opposite, by a flange (60) linked to a central axis (61) turn nant in a sleeve (62) integral with the frame and connected by a coupling (63) to a rotary actuator (64) ensuring the rotations of the flange according to a half-turn.
Lorsque l'amorce est réalisée, la broche supérieure (55) est entraînée en rotation sur elle-même, afin de réaliser le bobinage et simultanément, le vérin rotatif (64) est actionné pour commander la rotation du flasque (60) suivant un demi-tour, afin d'amener la broche (57), donc les axes (58), en position haute, pour réaliser la bobine suivante.When the primer is made, the upper spindle (55) is rotated on itself, in order to carry out the winding and simultaneously, the rotary actuator (64) is actuated to control the rotation of the flange (60) by one half -turn, in order to bring the spindle (57), therefore the axes (58), in the high position, to produce the next coil.
Pendant ce temps, la première bobine continue de se former sur les axes (54). Lorsqu'elle est pratiquement terminée, la broche (55) est arrêtée (par le frein) avec les axes (54) replacés l'un au dessus de l'autre, et une lame (65) portée en bout d'un vérin (66) solidaire du bâti (traits interrompus, figure 13), est avancée pour engager les bandes dans les axes (58), jusqu'à ce que les boucles ainsi formées aient dépassé lesdits axes. Simultanément, des vérins de placage (67) à forme d'appui élastique (67a) sont avancés contre les bobines formées sur la broche (55). La lame (65) étant arrêtée en position avancée, un couteau pneumatique (68) du type à lame en forme de disque à facettes, guidé sur des colonnes (69), est poussé par un vérin central (70) pour couper les bandes (traits interrompus, figure 2). Après la coupe, la lame (65) est de nouveau actionnée pour assurer l'engagement complet des extrémités des bandes coupées dans les axes (58).During this time, the first coil continues to form on the axes (54). When it is practically finished, the spindle (55) is stopped (by the brake) with the pins (54) replaced one above the other, and a blade (65) carried at the end of a jack ( 66) secured to the frame (broken lines, Figure 13), is advanced to engage the strips in the axes (58), until the loops thus formed have exceeded said axes. Simultaneously, plating cylinders (67) in the form of elastic support (67a) are advanced against the coils formed on the spindle (55). The blade (65) being stopped in the advanced position, a pneumatic knife (68) of the blade type in the shape of a faceted disc, guided on columns (69), is pushed by a central jack (70) to cut the strips ( broken lines, Figure 2). After cutting, the blade (65) is again actuated to ensure complete engagement of the ends of the cut strips in the axes (58).
La broche (57) est alors entraînée en rotation pour réaliser le deuxième bobinage, tandis que la broche (55) est également entraînée pour finir d'enrouler la fin des bandes coupées. Puis les vérins de placage (67) sont reculés et une palette (71) est engagée par un vérin articulé (72), derrière les bobines terminées, afin de les évacuer par action d'un autre vérin (73), sur une balance électronique (74) fixée sur un châssis indépendant (75), afin d'éviter les vibrations.The spindle (57) is then driven in rotation to produce the second winding, while the spindle (55) is also driven to finish winding the end of the cut strips. Then the plating jacks (67) are moved back and a pallet (71) is engaged by an articulated jack (72), behind the finished coils, in order to evacuate them by the action of another jack (73), on an electronic balance (74) fixed on an independent chassis (75), in order to avoid vibrations.
La balance vérifie la longueur des bandes bobinées par pesée, cela, en fonction de leur densité connue. Si le poids ne corespond pas, une correction est effectuée automatiquement, par une cellule photo (non représentée) coopérant avec un disque denté, afin de modifier le comptage des dents par la cellule.The balance checks the length of the wound tapes by weighing it according to their known density. If the weight does not correspond, a correction is made automatically, by a photo cell (not shown) cooperating with a toothed disc, in order to modify the counting of the teeth by the cell.
En cas de défauts détectés par la caméra, la ou les bobines repérées sont éjectées latéralement de la balance, par des vérins (76) à forme d'appui, tandis que les bobines correctes sont éjectées vers un moyen de conditionnement, par une palette (77) engagée derrière lesdites bobines posées sur la balance, par un vérin articulé (78) et un vérin de poussée (79).In the event of faults detected by the camera, the identified coil (s) are ejected laterally from the scale, by cylinders (76) in the form of a support, while the correct coils are ejected towards a packaging means, by a pallet ( 77) engaged behind said coils placed on the scale, by an articulated cylinder (78) and a thrust cylinder (79).
Pour réaliser le déroulement des bandes en continu, il est nécessaire que la fin des bandes (bl - b2) déroulées des mateaux (2 et 4) soit accrochée automatiquement avec le début des bandes (b3 - b4) enroulées sur les mateaux (1 et 3), afin d'avoir toujours deux mateaux en attente.To carry out the unrolling of the bands continuously, it is necessary that the end of the bands (bl - b2) unrolled from the fabrics (2 and 4) is hooked automatically with the beginning of the bands (b3 - b4) wound on the fabrics (1 and 3), in order to always have two pending matches.
Pour cela, et comme illustré à la figure 3, on met en oeuvre un dispositif porté par la potence (14 ou 15) solidaire des montants (7a ou 8a) des magasins ou donneurs, et sur laquelle sont montés à rotation libre, les rouleaux d'alignement (12 - 13) des bandes (bl - b2), comme on l'a vu plus haut.For this, and as illustrated in FIG. 3, a device is carried carried by the bracket (14 or 15) secured to the uprights (7a or 8a) of the stores or donors, and on which the rollers are mounted with free rotation. alignment (12 - 13) of the bands (bl - b2), as seen above.
La potence est prolongée par un support (14a ou 15a) dont l'extrémité inférieure porte un rouleau d'alignement (80) pour les bandes (b3 - b4) déroulées des mateaux (1 et 3), pour fixer leurs extrémités libres équipées d'un adhésif double face, sur une pièce à surface accrocheuse (81) du type peau de phoque, par exemple, que l'on peut à cet effet tirer latéralement par rapport 'à son guide-support (82) porté par un bras (83) articulé en (84) à la potence.The bracket is extended by a support (14a or 15a), the lower end of which carries an alignment roller (80) for the bands (b3 - b4) unrolled from the mat (1 and 3), to fix their free ends fitted with a double sided tape, on a workpiece-catching surface (81) seal the skin type, for example, which may for this purpose take laterally relative 'to its support-guide (82) carried by an arm ( 83) articulated in (84) at the gallows.
Le bras (83) est également relié par une biellette (85) à un autre bras (86) se développant derrière le rouleau d'alignement (13) qui est articulé en (87) à la potence.The arm (83) is also connected by a link (85) to another arm (86) developing behind the alignment roller (13) which is articulated at (87) to the bracket.
Le bras (83) porte encore derrière le guide-support (82) un élément-support (88) pour une résistance (89) ; l'ensemble bras (83) - support (88), étant rappelé en position arrière par un ressort de rappel (90) attaché au pralongement (14a ou 15a).The arm (83) still carries behind the support guide (82) a support element (88) for a resistance (89); the arm (83) - support (88) assembly, being returned to the rear position by a return spring (90) attached to the extension (14a or 15a).
De la même façon, l'extrémité inférieure du bras (86) porte une résistance (91) et ces deux résistances sont destinées à agir alternativement pour couper les bandes de fin de mateau, après accrochage des bandes déroulées des mateaux neufs. Pour cela, on place derrière la pièce accrocheuse (81), un électro-aimant (92) ou autre moyen similaire à poussoir, fixé sur le prolongement (14a ou 15a).In the same way, the lower end of the arm (86) carries a resistor (91) and these two resistors are intended to act alternately to cut the end bands of the mat, after hooking up the unrolled bands of the new mats. For this, there is placed behind the hooking piece (81), an electromagnet (92) or other similar means to push, fixed on the extension (14a or 15a).
On comprend que lorsque les mateaux (2 et 4) sont presque vides, l'électro-aimant (92) est actionné pour pousser la pièce accrocheuse (81) contre une pièce (93) à surface rugueuse qui est montée fixe derrière les bandes (bl - b2), dans le même alignement, mais avec possibilité de déplacement latéral dans son guide.It is understood that when the plates (2 and 4) are almost empty, the electromagnet (92) is actuated to push the catching piece (81) against a piece (93) with a rough surface which is fixedly mounted behind the strips ( bl - b2), in the same alignment, but with the possibility of lateral displacement in its guide.
Dans cette action déclenchée pendant que les bandes (bl - b2) continuent de se dérouler, la deuxième face de l'adhésif assure le collage des bandes (b3 - b4) en attente, tandis que le bras (86) ramené contre les bandes (bl - b2) par l'effet des articulations bras, biellettes, permet à la résistance (91) qui est alimentée de couper les bandes (bl - b2) derrière le collageIn this action, triggered while the strips (bl - b2) continue to unroll, the second side of the adhesive ensures the bonding of the waiting strips (b3 - b4), while the arm (86) brought back against the strips ( bl - b2) by the effect of the arm and link joints, allows the resistance (91) which is supplied to cut the strips (bl - b2) behind the bonding
Inversement, lorsqu'on veut raccorder en continu des bandes neuves (bl - b2) à des fins de bandes (b3 - b4), on tire latéralement la pièce accrocheuse (93) pour y fixer les extrémités des bandes (b3 - b4) munies des adhésifs double face, puis on la remet en position d'attente. Lorsque les mateaux (1 et 3) sont presque vides, on actionne l'électro-aimant (92) pour assurer le collage des extrémités de bandes (b3 - b4) sur les bandes (bl - b2), puis la résistance (89) qui est seule alimentée, coupe les bandes (b3 - b4) derrière le collage.Conversely, when it is desired to continuously connect new strips (bl - b2) for the end of strips (b3 - b4), the hooking piece (93) is pulled laterally to fix the ends of the strips (b3 - b4) provided therein. double-sided tape, then put it back in the waiting position. When the mat (1 and 3) are almost empty, the electromagnet (92) is activated to ensure the bonding of the ends of the strips (b3 - b4) on the strips (bl - b2), then the resistance (89) which is only supplied, cuts the strips (b3 - b4) behind the collage.
Bien entendu, toutes les opérations de collage, coupe, règlage de défilement..., sont pilotées de toute manière connue, notamment par un automate programmable.Of course, all the operations of bonding, cutting, scrolling adjustment, etc., are controlled in any known manner, in particular by a programmable controller.
