Definitions

  • the invention initially relates to a method for positioning a plurality of additional devices of a bag-making machine, which are spaced apart in the intermittent region along a movement path of a material web, in particular a plastic film web, in front of a welding device .
  • the material web is corresponding to the distance of a repeat length or a multiple edited in order to produce in this way flawless bags or tote bags.
  • the accessories are single or too several mounted on a carriage, which is adjustable in the longitudinal direction of the web is stored. Changes in the repeat length have hitherto been carried out by means of a sensor device, for example, a photocell, detected and then the or the car with the on it additional devices in a corresponding to the Rapportinnver selectedung move to a more optimal position.
  • a sensor device for example, a photocell
  • the invention is based on the object, a method of the type mentioned to propose, by a quick and accurate repositioning or repositioning of Additional equipment is achieved. Furthermore, a device is to be created by the Um- / or Repositioning is ensured by simple means.
  • a material web for example a plastic film web 1
  • moves according to the arrow 2 from right to left can be.
  • the plastic film web becomes intermittent in the area of interest moved to each in the downtime of the plastic film 1, this according to the to be able to process the given repeat length R.
  • a first processing device is as Welding device 3 is formed, which has an upper welding bar 4 and a lower welding roller 5 has.
  • the welding device is explained in more detail below Considerations at a position zero. Starting from this zero position are contrary to Movement direction of the plastic film web 1 further bag positions P1 to P6 shown. at P6, for example, ventilation holes 6 are introduced, while at P5 a corner weld. 7 takes place. At positions P3, P4 theoretically further additional work could be carried out if this is necessary for the bag or bag to be made. in the illustrated embodiment is finally shown in the position P 2 yet that Suspension openings 8 are introduced.
  • the processing on the individual bag positions is done with the help of additional equipment 9, as this for example, shown in Figure 2 on a smaller scale.
  • the attachment 9 has each according to the work to be carried out tools not shown.
  • points each accessory, a control unit 11 with an input option of the respective position P1 to P6 on Each attachment is on the control unit 11 and a drive member 12 and a Drive motor 13 with a cooperating displacement transducer via control lines 14, 15 with a computer 16 of a controller 17 in conjunction, which finally with a arranged in the field of plastic film 1 photocell 18 as a sensor or control element cooperates for any deviations of the feed length of the plastic film web 1.
  • a drive gear 19 is coupled with the a rack arranged on the machine frame 21 in the longitudinal direction of the plastic film web 1 22 cooperates.
  • control device 17 and the drive device can be Reposition the attachments 9.
  • the accessories 9 each to a feed length of 300 mm between the individual positions P1 to P6 set.
  • the repeat length due to Railway tension changes quite, for example, from 300 mm to 302 mm.
  • this difference length of 2 mm starting from the zero position, with the number of bags to respective position of the attachment, e.g. for the bag position 4 an error of 8 mm.
  • gears and racks instead of gears and racks, another adjusting device can be used, which has, for example, a longitudinally adjustable spindle.

Claims (4)

    la valeur de correction est transmise à chacun des appareils supplémentaires (9) qui sont finalement positionnés dans leur position correcte par une course de positionnement déterminée à partir de la valeur de correction multipliée par l'écart de position correspondant de l'appareil supplémentaire (9) concerné par rapport à une position zéro fixée, le dispositif de soudage (3) se trouvant à la position zéro.
  2. Dispositif pour mettre en oeuvre un procédé selon la revendication 1 ayant les caractéristiques suivantes :
    un capteur unique, notamment une cellule photoélectrique (18), détermine les écarts entre la longueur d'avance réelle de la bande de matière et la longueur d'avance de consigne en vue de modifier l'avance de la bande de matière,
    un moteur d'entraínement commandable (13), un capteur de course agissant conjointement avec le moteur d'entraínement (13) ainsi qu'un dispositif de transmission (19, 22) pour chaque appareil supplémentaire (9), et
    un dispositif de commande avec un ordinateur (16) qui traite les écarts déterminés par le capteur entre la longueur d'avance réelle de la bande de matière et la longueur d'avance de consigne en vue d'obtenir une valeur de correction, laquelle est transmise à chacun des appareils supplémentaires (9) et qui positionne les appareils supplémentaires (9) dans leur position correcte par une course de positionnement déterminée par rapport à une position zéro fixée à partir de la valeur de correction multipliée par l'écart de position correspondant de l'appareil supplémentaire (9) concerné, et
    un dispositif de soudage (3) qui se trouve à la position zéro.
  3. Dispositif selon la revendication 2, caractérisé en ce que le dispositif de transmission est formé par une roue dentée d'entraínement (19) couplée au moteur d'entraínement (3) et une crémaillère (22) agissant conjointement avec celle-ci ou alors par un dispositif de positionnement présentant une broche positionnable dans le sens longitudinal.
  4. Dispositif selon la revendication 2 ou 3, caractérisé en ce que chaque appareil supplémentaire (9) présente une unité de commande (11) avec une possibilité de saisie de la position correspondante (P1 - P6) des appareils supplémentaires (9).
