Definitions

  • the stacks to be processed by sheet layers often show such a large offset that an additional lateral pre-correction of the entire stack or else of the sheet on the feed table is necessary.
  • the transfer errors in the sheet separation can be taken into account in an advantageous manner.
  • the evaluation result can also be influenced by simply adjusting their distance.
  • the transport device that feeds the sheet 5 of the machine 6 or a cylinder 7 of the machine 6 is first formed by a feed table 8.
  • Endless conveyor belts 9, which are driven by a deflecting roller 10, are arranged on this at certain intervals (see FIG. 2), two deflecting rollers 10, 11, which extend over the entire width, being provided in the sheet running direction before and after the feed table.
  • a further roller 12 also regulates the tension of the conveyor belts 9.
  • These are each assigned a plurality of transport rollers 13 on the feed table 8 and clock rollers 15 which are mounted in a longitudinally displaceable manner on a crossbar 14 by means of a support arm 26. Depending on the sheet processing speed of the machine 6, these are placed on or off the already separated sheets 5 in cycles, which is caused by the crossmember 14 which can be pivoted about its axis.
  • a further traverse 16 is provided, extending over the width of the sheet feeder 1 determined by the side parts 27.
  • optical detection devices designed as reflective light barriers 19, 20 are fastened thereon by means of brackets 17 which can be locked on the crossbar 16 by means of clamping screws 18.
  • the control signals for triggering the corrective movement of the stacking table 3 result from the different light reflectance when it hits the white paper sheet 5 or in the "empty space".
  • the evaluation result can be made variable, for example by adjusting its distance.
  • both reflective light barriers 19, 20 are assigned to a lateral sheet edge 21.
  • the sheets 5 are separated outside a certain tolerance range and assume the position shown in broken lines in FIG. 4, they are detected by both reflective light barriers 19, 20, which results in a specific actuating signal. This is transmitted to a servomotor 24, which laterally adjusts the stacking table 3 by a predetermined amount in the corresponding direction (to the right).
  • An actuating signal for the stack movement in the other direction is issued when, in an equivalent manner, the separated sheets 5 assume the position shown in dashed lines in FIG. 4 (both reflective light barriers 19, 20 go into the “empty space”).
  • a further possibility would also be to assign a reflection light barrier 19, 20 to each of the two lateral sheet edges 21, 23. Additional information regarding the sheet width could be derived from this.
  • T a specific response time of the reflex light barrier 19, 20 in question.
  • the number of sheets 5 from which the servomotor 24 carries out a corrective movement of the stack 2 can advantageously be predetermined.
  • the transfer errors in the sheet separation can be taken into account in an advantageous manner, so that finally the side drawing mark 25 has only a slight final alignment for the exact registration of the sheets 5.
  • the device shown is an extremely short reaction time to realize.

Claims (4)

1. Margeur pour machine travaillant les feuilles, présentant les particularités suivantes:
à une pile (2) composée des feuilles (5) à travailler, sont associés un dispositif de séparation (4) agissant sur les feuilles, un dispositif de tranport (8 à 15) servant à acheminer les feuilles séparées à la machine (6), et un dispositif servant à l'alignement automatique de la position latérale de la pile;
le dispositif servant à l'alignement automatique de la position latérale comprend un moteur de positionnement (24) qui est en liaison effective avec une table porte-pile (3) qui porte la pile et qui est montée de façon à pouvoir se déplacer transversalement par rapport à la direction de transport des feuilles; et
un dispositif de détection de la position réelle des feuilles qui envoie des signaux de positionnement au moteur de positionnement,
le dispositif de détection de la position réelle des feuilles présente un capteur de position réelle des feuilles, travaillant sans contact, disposé immédiatement en aval de la pile, considéré dans le sens du transport des feuilles, caractérisé en ce que
le capteur de la position réelle des feuilles estformé de deux dispositifs photoélectriques à réflexion qui sont montés mobiles en translation longitudinale sur la traverse (16) qui s'étent transversalement à la direction du transport des feuilles, et
peuvent être bloqués sélectivement à des écartements mutuels pouvant être choisis,
de part et d'autre d'un bord latéral choisi (21 ou 23)
ou encore de part et d'autre des deux bords latéraux (21 et 23) d'une feuilles qui est saisie par le dispositif de transport.
2. Margeur selon la revendication 1, caractérisé en ce que, dans le cas où les deux dispositifs photoélectriques à reflexion sont associés à un seul et même bord latéral d'une feuille, cette feuille est intéressée par un seul des deux dispositifs photoélectriques à réflexion dans le cas où la feuille est acheminée dans les limites d'une certaine tolérance tandis que, dans le cas où le transport des feuilles demande une correction, la feuille n'est intéressée par aucun des dispositifs photoélectriques à réflexion ou encore est intéressée par ces deux dispositifs.
3. Margeur selon la revendication 1, caractérisé en ce qu'un signal de positionnement envoyé au moteur de positionnement (24) est produit en fonction d'une certaine durée de réponse (T) du dispositif de détection de la position réelle des feuilles (16 à 20).
4. Margeur selon la revendication 1, caractérisé en ce que la durée de réponse (T) est réglable par pas successifs, un pas de temps correspondant à un intervalle de temps (T1= I/v) qui résulte de la longueur ( 1 ) des feuilles et de la vitesse de transport (v), et pendant lequel une seule feuille (5) active le dispositif de détection (16 à 20), T pouvant de préférence être inférieur ou égal à Tl, ou encore égal à un multiple entier de Tl.
