Definitions

  • the invention relates to a transport device for feeding and discharging an endless form to a platen roller, which is mounted in the frame walls of a printing unit, with paired transport chains, which capture the form around the platen roller in front of and behind the platen roller and arranged on shafts mounted in side walls of the transport device are, at least one of which can be driven.
  • the known arrangement has the disadvantage that the rigid coupling means that the distance between the transport chains and the platen roller always remains constant during operation, so that the continuous forms inserted are only under the same tension during transport if they always have the same thickness.
  • the invention has for its object to provide a transport device that can be easily adjusted to different forms or sets of forms with different strengths and in which the effort required for this is low.
  • an actuating lever is pivotally mounted on at least one of the two side walls of the device, which on the one hand has an attachment for ratcheting in different pivot positions and on the other hand has a bearing eyelet with which the side walls in the corresponding pivot positions of the actuating lever on the Frame walls of the printing unit are fastened by bolts, and that the side walls are each provided with an elongated hole which engages around a further bolt fastened to the frame walls, such that when the actuating lever is pivoted, the side walls slide in the elongated holes and the distance between the transport chains and the Platen changes.
  • the entire transport device can be plugged onto the printing unit as a modular unit.
  • the two actuating levers arranged on the side walls of the transport device can be individually supported or can also be connected to one another in a rotationally fixed manner. While in the first case each actuating lever has to be moved individually and has to have its own catch, in the second case the pivoting and catch of one of the two actuating levers is sufficient.
  • the transport device for continuous forms is designed as an easily assembled, attachable assembly.
  • a clamp connection was chosen to enable easy placement on the printing unit.
  • the side walls 1 and 2 each have an open slot 3.
  • the bolts 4 and 5 for inserting the transport device onto the printing unit are fastened to the frame walls 6 and 7 (FIG. 1), which are components of the printing unit.
  • the cladding 8 of the printing unit which is only partially shown in FIGS. 2 and 3, has an opening on the right and left of the platen roller 12 which enables the side walls 1 and 2 to be inserted.
  • Fig. Shows how the transport device is plugged on. By tilting the transport device to the front, the elongated holes 3 are inserted over the bolts 4 and the transport device is then pivoted back again until the clamping lugs 9 and 10, which form a bearing eye, snap into place over the second bolt 5.
  • the side walls 1 and 2 are each provided with an edge 11 which is in the functional position the transport device rests on the associated pin 5 and prevents further pushing through when plugging in and relieves the bearing eye.
  • the teeth of the gear 13 fastened on the platen roller 12 and the gear 14 located on the transport device engage and represent the transmission for power transmission from the platen roller 12 to the drive shaft 21 of the transport chains 16.
  • the transport device can also be detachably held on the printing unit in another way. It should only be noted that the transport device can be moved on the printing unit by the actuating lever 15.
  • the distance A must be variable depending on the form thickness or depending on the number of form layers.
  • a particularly favorable solution is the fixed assignment of the distance A to the form thickness or to the form layers.
  • the distance between transport chains 16, in particular their drive shaft 21, and the platen roller 12, in particular their bearing shaft 22, is made adjustable.
  • the actuating lever 15, which at the same time effects the releasable fastening of the transport device on the printing unit.
  • the actuating lever 15 is fastened in the pivot bearing 17 on the side walls 1 and 2 of the transport device. It has an integrally formed arm 18 in the upper part, which acts as a fixing spring. This engages in four positions, which are punched as elongated holes 19 in the side walls 1 and 2.
  • the actuating lever 15 rotates about the bolt 5.
  • the transport device is described and illustrated in such a way that it can, if necessary, be placed on and removed from the frame of the printing unit. For this reason, the elongated holes and the bearing eyelets 9, 10 are each open to the outside. However, if the transport device can be firmly connected to the frame and does not have to be removable, it is also possible to make the elongated holes and the eyelets closed. In this case, the bearing bolts 4, 5 are then to be inserted into the assigned holes either during assembly of the printer or by resilient bending of the side walls 1.
