Definitions

  • the invention relates to a drive station on a device for drawing in material webs - preferably a paper web drawing device in web-fed rotary printing presses - according to the features in the preamble of patent claim 1.
  • a generic device is known from DE-C 35 05 515.
  • a feed element is driven by a transport wheel which is rigidly mounted above the same.
  • the distance between the transport wheel and the feed element is selected so that the former protrudes into the travel path of the latter to such an extent that the teeth on the outer circumference of both parts can come into non-positive engagement.
  • a spring-loaded ball protrudes from below into the path of the feed element, which actuates a switch for the connection of a motor driving the transport wheel with the interposition of a drive gear when the same runs in.
  • the ball also has the function of pushing the feed element up and thus ensuring its positive engagement with the teeth of the transport wheel.
  • the running-in process at this drive station is also not smooth if one tooth head of the pull-in element and the transport wheel meet.
  • the invention has for its object to provide a drive station that enables a highly wear and jerk-free transport of a feed element.
  • pull-in elements flexible rope-like elements with a circular or polygonal cross-section, rope-like elements which are additionally provided with a helical spiral on the outside or chain-like elements.
  • all of the retraction elements are suitable for the drive station according to the invention, which allow a positive engagement of a toothed transport wheel.
  • a pull-in element 1 is formed on the circumference of the cable by a flexible cable 2 with a circular cross section and a helical coil 3 firmly connected thereto, as can be seen in FIG. 1.
  • a plurality of fastening elements 4 are arranged, to which a flexible pull element 5 is fastened.
  • a paper web (not shown) is connected to this before the drawing-in process.
  • the feed element can be moved in a tubular guide 6 with a circular cross section.
  • the guide 6 has a slot 7 on one side, through which the fastening members 4 are guided.
  • Drive stations 8, one of which is shown in FIG. 2 are arranged at intervals along the printing press.
  • Each drive station 8 consists of a base plate 9 to which the guide 6 is fastened and on which all other elements required for the drive are mounted.
  • the base plate 9 is in turn attached to a machine side wall of the printing press (not shown).
  • the guide 6 at least instructs in the area of a drive station 8 a recess on its upper side, through which an externally toothed transport wheel 10 partially projects into the guide.
  • the guide 6 can, however, just as well, as shown in FIG. 2, be interrupted over part of its length.
  • both ends 6 a and 6 b of the guide 6 are fastened to the base plate 9 in alignment with their longitudinal axis.
  • the feed element 1 is supported in the region of the tooth engagement of the transport wheel 10 from below by a counter pressure roller 11.
  • the transport wheel 10 is in engagement with a drive wheel 12 which can be driven by a motor 14 fastened to the base plate 9 by means of a flange 13.
  • the motor 14 is preferably designed as a pneumatic motor.
  • a bearing 16 receiving the axle ends 15 of the transport wheel 10 is, according to the invention, opposite the longitudinal axis of the feed element 1 against the direction of travel of the same at an acute angle ⁇ against a force F movable.
  • the forces acting on the transport wheel 10 can be better seen in the schematic illustration in FIG. 3.
  • the force is introduced into the transport wheel 10 by the drive wheel 12 at the common point of contact 17.
  • the force is diverted from the transport wheel 10 to the feed element 1 at the common point of contact 18.
  • the pitch circle tangents in the points of contact are designated 17 a and 18 a. They are identical to the lines of action of the forces acting on the transport wheel 10 in these points, the driving force F17 and the reaction force F18 of the feed element 1 on the transport wheel 10.
  • the drive wheel 12 is always arranged to the transport wheel 10 so that the bisector 19 at an acute angle ß / 2 against Running direction of the feed element 1 is inclined. This always results in a resultant force F res on the transport wheel 10 during operation, which pulls the transport wheel 10 into the wedge formed from the pitch circle tangents 17 a and 18 a; and the stronger, the greater the transmitted driving force F17 or F18.
  • the transport wheel 10 is easily movable in the opposite direction, ie out of the wedge formed by the pitch circle tangents. So it can easily move upwards when the feed element 1 runs in.
  • the force F against which the transport wheel 10 is moved is very low. It should only bring about the first tooth engagement of the transport wheel 10 with the feed element 1.
  • the force on the bearing 16 of the axles 15 of the transport wheel 10 is exerted by a compression spring 20; with a corresponding mass of the transport wheel 10, the weight of the same will be sufficient to produce the tooth engagement.
  • a spring 20 is preferred, the force of which likewise acts on the transport wheel 10 at an acute angle ⁇ counter to the running direction of the feed element 1.
  • the angle ⁇ is preferably between 30 ° and 70 °, in a particularly preferred embodiment at 45 °; Also advantageous is an arrangement in which the angle ⁇ corresponds to the angle ⁇ , because the transport wheel 10 is displaced tangentially to the drive wheel 12 and the meshing is best maintained.
  • a switching element 21 cooperating with the bearing 16 of the transport wheel 10 is provided, which actuates a switch 22 when the transport wheel is moved, as is indicated schematically in FIG. 3.
  • the switching element 21 is designed as a bolt, which is supported with one end on the bearing 16 and the other conically ground end is guided in a bore 23 of a switch housing 24.
  • the shaft of the bolt also serves to guide those surrounding it at a short distance Spring 20.
  • a blind hole 25 is arranged in the switch housing 24 at right angles to the bore 23.
  • a ball 26 is supported, which is supported on the conical end of the bolt and is pressed by the bolt into the bore 25 when the transport wheel 10 is displaced. It actuates a pneumatic switch 27 which, directly or indirectly to reduce the switching force required, sets the motor 14 into operation via a pneumatic booster stage.
  • the drive wheel 12 and the transport wheel 10 meshing with it are set in rotation.
  • the entire drive station 8 acts in the running direction of the feed element 1 as an overrunning clutch or freewheel: As long as the feed element 1 is still from a further back drive station or as soon as it is moved by a preceding one again at a greater speed than the peripheral speed of the transport wheel 10 under consideration, the latter deviates the angle ⁇ obliquely upwards. However, as soon as the driving force of the drive station under consideration becomes effective after the run-up, the tooth engagement between the transport wheel 10 and the feed element 1 is automatically maintained due to the resulting force F res described further above.
  • the oblique displacement of the bearing 16 shown in FIGS. 2 and 5 is provided in a slot-like guide 28, in which the ⁇ angle remains unchanged.
  • a pivoting of the transport wheel 10b on a circular arc 29 around the axis of the drive wheel 12b is also possible, in which the angle ⁇ varies slightly with the small pivoting distance to be covered.
  • the transport wheel 10 b is mounted in a pivoting lever 30 which can be rotated about the axis of the drive wheel 12 b.
  • a spring 20 b acts on the latter, the force of which acts analogously to that of the spring 20 in FIG. 3 in the direction of the wedge formed by the pitch circle tangents.
