Definitions

  • the innovation relates to a sheet delivery on rotary printing presses, in which the fed sheets are deposited on a lowerable deposit table to form a sheet stack, with a bar grate that can be inserted when the sheet stack is full, as an intermediate stacking device which, when inserted, has its front, free end on a support discards.
  • DE-PS 35 35 113 shows such a sheet boom with a lowerable support of the bar grate.
  • the disadvantage of this known device is that e.g. When using euro pallets that are larger than the maximum sheet format, the support of the intermediate stacking device collides with the euro pallet when the same is being raised. As a result, the function of the intermediate stacking device is considerably impaired. There is also the risk that the intermediate stack will be damaged or shifted by means of transport for the sheet feed, so that this also results in expenditure and costs.
  • this object is achieved in that the support is designed as a rail which is mounted horizontally displaceably from the area of the sheet stack by means of adjusting means.
  • the actuating means are arranged on both sides of the rail and are designed as pneumatic cylinders, the rail being mounted on the piston rods of the pneumatic cylinders.
  • the shifting of the rail can be linked in terms of circuitry with the retraction or extraction of the bar grate.
  • the pneumatic cylinders are mounted on supports which can be lowered as the stack height of the intermediate stack increases. This lowering of the intermediate stacking device is necessary in particular when processing thicker sheet material in order to achieve an equal fall height of the sheets to be deposited.
  • the sheets 1 to be deposited from gripper bars 2, which are provided on a chain system 3, are fed to a sheet stack 4 in a known manner.
  • the sheet stack 4 rests on a not shown table, which can be lowered according to the increasing stack height. As soon as the sheet stack 4 has reached its full height, it is removed from the machine and an empty stack board is laid and moves it into its upper starting position to receive a new stack of sheets.
  • an intermediate stack 6 is formed on an insertable bar grate 5.
  • the bar grate 5 rests on a traverse 7 at its rear end.
  • a support 8 is designed here as a rail 9, which is mounted on both sides of the piston rods 10 of pneumatic cylinders 11.
  • the rail 9 can be moved with the support 8 to the right into the position shown in broken lines. In this position e.g. without using the intermediate stacking device, a pallet is placed on the lay-down table and the latter is moved into its upper receiving position without the pallet, which survives the maximum sheet format, colliding with the support 8.
  • the pneumatic cylinders 11 on both sides of the sheet stack are mounted on supports 12, to which the cross member 7 is also attached.
  • the carriers 12 are provided with a guide 13 which are guided in a roller bearing 14.
  • the carrier 12 and with it the bar grate 5 and the intermediate stack 6 can be lowered vertically by means of a lifting device (not shown). This lowering is necessary for non-stop operation, especially with thick sheet material and high machine speeds.

  1. Receveur de feuilles de machines à imprimer rotatives, dans lequel les feuilles alimentées sont déposées en pile sur une table abaissable, comportant, en tant que dispositif d'empilage intermédiaire, une grille à barreaux à introduire lorsque la pile de feuilles est complète, qui, en position introduite, se dépose avec son extrémité libre avant sur un appui, caractérisé en ce que l'appui (8) est conçu sous la forme d'un rail (9) qui est monté coulissant horizontalement, grâce à des moyens de réglage, à partir de la zone de la pile de feuilles (4).
  2. Receveur de feuilles selon la revendication 1, caractérisé en ce que les moyens de réglage sont montés des deux côtés du rail (9) et sont conçus sous la forme de vérins pneumatiques (11) et en ce que le rail (9) est monté sur les tiges de piston (10) des vérins pneumatiques (11).
  3. Receveur de feuilles selon les revendications 1 et 2, caractérisé en ce que les vérins pneumatiques (11) sont montés sur des supports (12) qui peuvent être abaissés lorsque la hauteur de la pile intermédiaire (6) augmente.
