Definitions

  • the invention relates to a device for transporting sheets printed in a printing unit with a chain system (EP-A 00 39 526) which is guided around a delivery drum and can be displaced in the longitudinal direction.
  • a chain system EP-A 00 39 5266
  • a section of the right chain 2 is shown, to which the ends of a gripper support spindle 3 and a gripper spindle 4 are fastened or guided.
  • they carry cross bars 3, 4, which are spaced apart from one another transversely to the transport direction, between two chains, the gripper support 5 of which is rotatably mounted on the gripper support spindle 3 and the gripper tongues 6 of which are mounted on the gripper spindle 4.
  • the gripper tongues 6 are pivoted by rotating the gripper spindle 4 to detect and release an arc.
  • a gripper control roller 7 running over a curve, not shown, is used for this.
  • the carrier plate 13 has on both sides with the elongated hole 14 and the bore 14 'corresponding elongated holes 21, 22, in which also engage the bolts 10, 11.
  • the roller 17 runs on or behind the delivery drum 1 on the curve 18, as a result of which the toggle lever 15 is pivoted in the clockwise direction.
  • the roller 23 positioned in the recess 24 also carries the carrier plate 13, to which the transverse bars 4, 5 are fastened, in the clockwise direction, that is to say in the transport direction F of the chain 2. It is thus advantageously achieved that the beginning of the sheet which is led out of the printing unit undergoes an acceleration in addition to the transport speed of the chain 2, which should continue until the sheet end has left the printing line by the appropriate formation of curve 18.
  • a stop 25 limits the pivoting movement of the lever 15 in the counterclockwise direction.

1. Dispositif pour transporter des feuilles imprimées dans un groupe imprimant, comprenant un système de chaînes (2) qui embrasse un tambour de réception (1) et qui guide des pinces (5, 6) mobiles en translation dans la direction longitudinale, caractérisé en ce que chacune des barres transversales (3, 4) qui portent les pinces (5, 6) est fixée latéralement à une plaque support (13) qui présente des trous allongés (21, 22), cette plaque support étant elle-même montée mobile en translation sur un étrier (12) disposé sur le côté de cette plaque support qui est à l'opposé des barres transversales (3, 4) et qui présente à ses extrémités (figure 2) deux perçages (14, 14') qui correspondent aux trous allongés (21, 22) et dont l'un (14) est un trou allongé, de telle sorte que, dans les trous allongés (21, 22) et les perçages (14, 14') sont respectivement engagés deux axes (10, 11) fixés à la chaîne (2) à un certain écartement mutuel, de sorte que la plaque support (13) peut se déplacer en translation dans le sens du transport par rapport à l'étrier (12), en ce qu'à l'étrier (12) est articulé un levier de commande coudé (15) à une des extrémités duquel est disposé un galet (17) roulant sur une came (18) située derrière le tambour de réception (1) et qui fait pivoter ce levier, tandis que son autre extrémité est engagée dans un évidement (24) de la plaque support (13), de telle sorte que, lors du franchissement de la came (18), la plaque support (13) subit un mouvement d'avance additionnel, rapporté à la direction (F) du défilement de la chaîne.
2. Dispositif selon la revendication 1, caractérisé en ce que l'une des extrémités du levier de commande (15) est engagée, par l'intermédiaire d'un galet (23), dans un évidement allongé (24) prévu dans la plaque support (13), et orienté à peu près transversalement à la direction du défilement de la chaîne.
2. Dispositif selon une des revendications précédentes, caractérisé en ce que le levier de commande (15) est sollicité par un ressort de compression (19) qui agit dans le sens inverse du sens du défilement de la chaîne.
4. Dispositif selon une des revendications précédentes, caractérisé en ce que les axes (10, 11) constituent des prolongements des axes (8, 9) de la chaîne.
5. Dispositif selon une des revendications précédentes, caractérisé en ce qu'une butée (25) limite le mouvement du levier (15) en dehors de la région active de la came (18), dans le sens inverse de celui des aiguilles d'une montre.
