Definitions

  • the invention relates to a transport device for paper webs with two tractors per paper web, which are arranged on two associated bearing shafts and can be driven by at least one bearing shaft and each have an endless transport chain with pins with holding flaps pivotable on their long sides, in which the paper web has one long side of the assigned tractors is fed to the pressure abutment, guided around it and discharged via the other longitudinal side of the assigned tractors, and a guide piece is arranged on the end of the assigned tractors facing the pressure abutment, around which the paper web is guided in a curved manner in front of the pressure abutment.
  • Such a transport device is known from DE-A-20 62 806.
  • the double-sided guidance of the paper web on the tractor ensures good guidance by 180 ° around the pressure abutment designed as a roller. Since the paper web can expand or shrink depending on the air humidity, a deflection member designed as a roller is arranged on the tractor, which ensures that the paper always rests on the printing roller under approximately the same tension.
  • the invention has for its object to provide a transport device of the type mentioned that displacement and bulging of the paper layers of the paper web to each other is largely avoided and that an easy and convenient insertion of the paper web in the tractors is possible.
  • the guide pieces extend continuously from the front of the tractor to the contact area in which the supplied paper web touches the pressure abutment, that the two tractors can be pivoted about the other bearing shaft with one of their two bearing shafts, and that the guide pieces pivot when swiveling the tractors are led over the surface of the pressure abutment into the swivel position.
  • the tractors with the guide pieces can be pivoted about one of their two bearing shafts, the guide pieces then being moved over the pressure abutment when the tractors are pivoted away.
  • the guide pieces on the assigned tractors In order to render manufacturing tolerances ineffective, it is expedient to articulate the guide pieces on the assigned tractors and to support them with their front part on the pressure abutment.
  • the respective guide piece with a sliding element, for. B. a roller, roller or a felt covering on the front part.
  • the paper webs are particularly well inserted into the underside of the tractors when they are pivoted about the rear bearing shaft, which is arranged away from the pressure abutment.
  • the front bearing shaft is supported on the rear. It is also possible to connect the guide pieces to the assigned tractors in an articulated rather than flexible manner. In order to guide the guide pieces over the pressure abutment in this case, the distance between the pressure abutment and the two tractors must be increased by moving one of these parts to such an extent that the tractors can be pivoted freely with their guide pieces.
  • the transport device shown in the figures consists of the side parts 20 and 21, which are fastened to a booking machine frame via straps in a known manner.
  • the two side parts are firmly connected to one another by the bearing rod 16 and the stop rod 19. It is also on these side parts 20 and 21 attached a connecting plate 22, which is not shown in Figure 1.
  • the rear bearing shaft 6 is supported in the side parts 20 and 21. This is driven synchronously with the pressure abutment 4 designed as a roller via the gear 17 by an electric motor (not shown). However, it can also be rotated manually by the handwheel 10.
  • the electric motor is not slotted to insert the paper web, so that the paper is fed by hand.
  • the rear bearing shaft 6 two tractors 2 are arranged so that the endless transport chains stored in the tractors are moved by it. These transport chains have pins 1 and 1a, which engage in the perforation at the edge of the paper web and thereby transport it.
  • the front bearing shaft 15 is also rotatably supported via connecting lever 18. This makes it possible to pivot the tractors around the rear bearing shaft 6, as is indicated in FIG. 1 for a tractor. In the operating position, the tractors 2 rest on the bearing rod 16 while they rest on the stop rod 19 in the pivoted-off state.
  • the pivoted position of the tractors 2 can be seen in FIG. 3.
  • their retaining flaps 3 are pivoted sideways. Since the underside of the tractors 2 is directed towards the operator, inserting the paper web 7 is easy and convenient.
  • the holding flap 3 is moved back and the tractors are pivoted back into their working position. This working position is shown in Fig. 2.
  • the paper web 7 is then inserted into the pressure device 8 with a pressure roller and placed around the pressure roller 4.
  • the pressure device 8 remains pivoted away from the pressure roller 4 during operation.
  • the retaining flaps 3a are pivoted upward, so that the paper web 7 with its perforation holes can be inserted into the pins 1 of the transport chains in a manner known per se. After the holding flaps 3a have been pivoted back, the clamping process of the paper web 7 is ended.
  • the individual webs are stapled together in the area of the perforation holes. Since the paper web 7 wraps around the roller by 180 ° with such a transport guide, the webs close to the roller 4 are guided on a narrower radius of curvature than the outer webs of the paper web 7.
  • the outer paper layer runs with the required tension around the pressure abutment 4, while the inner layers experience a back pressure through the pressure abutment and form a large wave in front of the pressure abutment 4, which grows on longer paper webs and destroys the so-called crimp-lock adhesion.
  • rollers or sliders can also be used.
  • the spring 12 is stretched until the connecting line of its fastening points has swept over the bearing axis 11.
  • the guide piece 9 is then guided and held in its pivoted stable position by the spring force 12. This stable position is chosen so that the free end of the guide piece 9 is no longer hindered by the roller 4.
  • the guide pieces 9 are still in their pivoted-down position or, if they had to be pivoted back into their working position so as not to impede pivoting of the retaining flaps 3, back into the stable position have been pivoted back, the free end of the guide pieces 9 strikes a stop 14 of the connecting plate 22 shortly before the operating position of the tractors is reached.
  • This situation is indicated by dashed lines in FIG. 3.
  • the course of the stop 14 is to be selected so that the front edge of the free end of the guide piece 9 occurs at an acute angle, so that when the tractors 2 are pivoted further, the guide piece 9 slides on the surface of the stop 14 until the spring 12 again exceeds its dead center position Has.
  • the guide piece 9 is held resiliently against the roller 4 by the spring 12. Since no great forces have to be exerted by the spring 12, it can be dimensioned in such a way that the guide piece 9 abuts the roller 4 only slightly.
  • the guide piece 9 has the shape of a bracket and is adapted to the width of the tractors.
  • other shapes are also conceivable.
  • the guide piece 9 has a slightly curved surface over which the paper web 7 slides.
  • the outer paper layer which runs in under tension, exerts constant pressure over the entire sliding surface, so that the inner paper layers have no possibility of forming a large wave.
  • the surface of the guide piece 9 is formed in a straight line, the paper web exerts different tensions on this surface which are greater at the beginning and end of the surface than in the area in between. This can create many small waves in the paper web distributed over the sliding surface, but these cannot destroy the crimp-lock adhesion of the individual paper layers.
