Definitions

  • the present invention relates to a drawing or cut ⁇ ting machine of the type having a table plate having at one end a reel holder for a supply reel of paper or another web that is to be treated on the table plate when laid out thereover, and at the opposite end a driv ⁇ ing mechanism for advancing the web over the table plate, while a coordinate-controlled drawing or cutting head is mounted on a transverse, which is movable along the table plate.
  • Machines of this type are usable for automatized cutting of sign texts and symbols in a self adhering plastic web, which, carried on a backing sheet, can be unreeled as a continuous web from a supply reel; after the cutting of the relevant cutting lines the desired letters or symbol details may be left on the backing sheet while the remainder of the plastic web is drawn off therefrom. It is important that for different orders webs of different widths may be used, viz. such that the waste of plastic web material may be kept at a required minimum, and for this reason the web driving mechanism should be able to advance both wide and narrow webs. For several reasons it is also important to make use of a steady reference location of one edge of the various webs, no matter their respective widths, i.e. the webs should always be laid out and advanced with one edge located in a well defined manner closely adjacent one side of the table plate.
  • the driving mechanism which may be a driving roller, should be located at the table end close to the selected side edge of the table, such that also quite narrow webs can be advanced, when a new web is desired.
  • the driving mechanism which may be a driving roller
  • a driv ⁇ ing mechanism having a relatively small width is suffi ⁇ cient to advance even much wider webs, i.e. these can be advanced solely by a driving engagement at a narrow edge area thereof.
  • the driving mechanism can cooperate with but a quite narrow width or partial width of the webs, inasfar as this makes it possible, without associated disadvantages, to effect variations of the direction of the driving roller or preferably a pair of cooperating driving rollers in response to an automatic detection of the location of the web edge, in order to achieve that the web edge is guided into a correct loca ⁇ tion whenever a deviation therefrom is detected.
  • the detection as well known per se, can easily be effected by sensors such as photo cells reacting to web edge locations respectively inside and outside the correct position, and the short driving rollers may then be angularly adjusted for producing an advancing which will immediately result in a lateral displacement of the web length into the correct position of the reference edge.
  • Fig. 1 is a perspective view of a drawing or cut ⁇ ting machine according to the invention.
  • Fig. 2 is a corresponding partial view thereof.
  • the drawing or cutting machine shown in Fig. 1 is built as a table with an elongate table plate 2, the opposed side edges of which have guiding tracks 4 for block heads 6 carrying between them a traverse 8, which carries a longitudinally movable holding head 10 for a drawing or cutting implement 12.
  • a horizontal supply reel 16 of a paper or plastic web 18, which can be drawn from the reel and laid out on the table 2 underneath the traverse 8 and the drawing or cutting head 12.
  • the web is drawn to the opposite end of the table 2, where there is mounted a cross cutting device 20 and a driving system 22, which, through a built-in pair of driving rollers, cooperates with a reference edge area of the web 18 adjacent one side of the table.
  • Fig. 2 is shown that the driving system 22 com ⁇ prises a pair of cooperating driving rollers 24, 26, which are mounted on a common carrier post 28 also car ⁇ rying a driving motor 30, which, internally in the post 28, is in driving connection with at least one of the rollers 24, 26.
  • the post itself is mounted rotatably about a vertical axis by means of a shaft pin 32 in a fixed socket portion 34.
  • a pair of sensors 42 and 44 which are located just outside and just inside, respec ⁇ tively, of the desired location of the relevant refe ⁇ rence edge of the web 18.
  • These sensors are connected with the motor 30 through a non-illustrated control unit in such a manner that the gear motor 40 will pivot the roller pair 24, 26 in the direction designated £, if the web edge is misplaced outwardly to cover the sensor 42, whereby the pair of rollers during the advancing of the web will impart to the web a lateral movement component so as to cause the web edge to be pulled inwardly until the sensor 42 is again uncovered, whereby the roller pair is triggered to pivot back to normal position.
  • the roller pair is pivoted in the direction II if the inner sensor 44 is uncovered, until it becomes covered again. Consequently the web edge can be guided with a high accuracy so as to assume its desired situa ⁇ tion at the end of each advancing operation.
  • gear motor 40 may be replaced by a mechanism, e.g. simple solenoids, that can effect a pivoting of the roller pair 24, 26 between only three positions, viz. an accurately transverse position and slightly angularly offset positions at respective opposite sides of that transverse position.
  • the web be advanced exclusively by a controlled rotation of the rollers 24, 26 and not additionally by a resulting longitudinal movement of the roller pair, as the case may be when the roller pair is pivoted about the post pin 32.
  • the pivoting it is possible to arrange for the pivoting to take place about a vertical axis through the middle area of the roller pair, e.g. by means of a cranked pivot shaft.
  • the pair of driving rollers 24, 26 should be able to advance the web 18 in an accurate manner into a "con ⁇ tinuation position" on the table 2 irrespectively of the resistance of the supply reel 16 being more or less pronounced. For this reason it has been found important that the unreeling resistance be reduced to a minimum by arranging for the reel shaft 14 to be connected with sensing and driving means which, responsive to an occur ⁇ ring pull in the web 18, will give rise to a motor driven rotation of the shaft 14 for a practically fric- tionless unrolling of a new web length to the table 2.
  • the new laid-out web length by the computer controlled operation of the driving rollers 24, 26, may be delivered just in such a position, in which the draw ⁇ ing or cutting head 12 may resume its operation at the front edge area of the table for completing a previously initiated working, without giving rise to visible dis ⁇ placements between the respective sections of the draw ⁇ ing or the cutting lines and without the advancing of the web having to be watched or manually finely cor ⁇ rected.

Abstract

Dans des machines servant à découper un texte ou des caractères dans une bande à travailler en plastique, un mode d'utilisation connu consiste à employer une tête de travail (10) commandée par un système de coordonnées, qui agit sur un segment de bande (18) lequel est posé sur une table (2) et est déroulé depuis une bobine alimentatrice (16) de sorte que de nouveaux segments de bande puissent être posés sur la table si nécessaire. L'avance de la bande est assuré par un petit cylindre d'entraînement transversal (24) placé sur un côté de l'extrémité frontale de la table, le cylindre pouvant ainsi faire avancer des segments de bande à la fois larges et étroits dont un côté latéral doit toujours être situé le long d'une ligne de référence spécifique du dessus de la table. Pendant son avance, la bande peut facilement quitter cette ligne, avec un mouvement vers l'extérieur ou vers l'intérieur, et il est important de pouvoir placer le nouveau segment de bande dans une position correcte à la fois longitudinalement et transversalement. La présente invention assure un guidage latérale automatique de la bande (18) par une simple détection de la position de son bord de référence et par des opérations associées de réglage ou de modification de la direction transversale du cylindre d'entraînement (24, 26) qui sont destinées à imprimer un mouvement transversal compensatoire au segment de bande qui avance. Le mouvement dans le sens de la longueur est également régulable avec précision automatiquement.
