Definitions

  • the invention relates to a longitudinal folder with a braking distance according to the preamble of claim 1.
  • Longitudinal folding devices of this type are used in the printing industry above all in the final production of printed products, the printed products being pressed into the folding nip by the folding knife and being longitudinally folded therein. Because the direction of entry of the printed products into the longitudinal folding apparatus is transverse to their subsequent movement through the folding nip, they have to be braked before they pass through the folding nip.
  • brake brushes which gradually brake the incoming printed products by means of friction, are known in known longitudinal folding apparatuses, as are stationary stops against which the printed products abut and are thereby braked abruptly.
  • the friction between printed products and brushes also depends on the Surface quality of the printed products. Products made from smooth paper can hit the stop too quickly, while products made from rough paper of the same thickness and weight may not reach the stop.
  • the position of the brushes must therefore be adjusted practically with every print job in order to ensure the proper functioning of the longitudinal folder. Due to the variety of influencing parameters, the adjustment can often only be made empirically, which is associated with a high expenditure of time and costs.
  • the invention has for its object to provide a longitudinal folder with a braking distance.
  • the object is achieved by the features of claim 1.
  • the movable stop gently brakes the products, eg. B.
  • Printed products is achieved because the kinetic energy with which the products hit the current stop is reduced compared to the kinetic energy that is released when striking a stationary stop. If the difference between the input speed of the products and the speed of the running stop is chosen to be sufficiently small, the undesired effects mentioned as a result of the kinetic energy released can even be avoided entirely.
  • the movable stop very high input speeds of the products can be absorbed and the products braked gently.
  • a braking effect that is independent of the mass, thickness and surface properties of the incoming products can be achieved, so that different products can be processed without the longitudinal folder having to be adapted to them beforehand.
  • the longitudinal folding apparatus very particularly preferably comprises a control unit which controls a reduction in the speed of the stop on the braking distance.
  • a control unit which controls a reduction in the speed of the stop on the braking distance.
  • control unit has an input for a signal representative of the input speed of the products, the speed of the stop at changing ones can be controlled by the control unit Almost adjust the input speeds of the products.
  • a sensor for detecting incoming products is located upstream of the braking distance and coupled to the control unit, so that the control unit can synchronize the movement of the movable stop in such a way that a detected incoming product strikes the stop moving at approximately the input speed at the beginning of the braking distance.
  • the speed of the stop at the beginning of the braking distance may be lower than the input speed as long as the difference between the speeds is not so great that damage to the product appears possible. It can also be slightly larger; in this case, contact between the two will only occur later on the braking distance when the stop has become slower than the product.
  • the stop is arranged on a running endless belt which has a section parallel to the braking distance.
  • the endless belt can either be provided above a folding table having the folding gap as a retrofittable module of the longitudinal folder, or else the endless belt is arranged as a module firmly integrated in the longitudinal folder under the folding table.
  • the endless belt is a toothed belt on which the stop is welded.
  • the stop is designed as a circumferential cam, the direction of movement of which intersects a braking distance of the product at least on one path section.
  • a on a rotatable body e.g. B. a disc, a roller or an eccentric, arranged circumferential cam, the stop in a continuous movement, without reversing the direction of drive one end of the braking distance - that is, an out of contact with the product - back to its beginning - that is, a contacting - to be able to catch the next product there.
  • the rotatable body can either be provided over a folding table having the folding gap as a retrofittable module of the longitudinal folding apparatus, or else the rotating body having the cams is arranged as a module firmly integrated in the longitudinal folding apparatus under the folding table.
  • the body is a plurality of disks which are arranged axially next to one another and each have at least one cam on their circumference.
  • At least one endless belt is arranged on both sides of the folding nip, each carrying synchronously moved stops. Two endless belts per side of the nip are preferred. This ensures proper alignment of the braked product and makes it even more difficult to twist the product unintentionally with respect to the rebate gap.
  • At least one motor can be provided on both sides of the nip to drive the endless belts.
  • This motor can be a highly dynamic servo motor or an electric motor.
  • an embodiment is also possible in which a single motor drives the endless belts on both sides of the folding gap by means of a continuous shaft.
  • a speed of the stop at the beginning of the braking distance of at least 90% of the input speed of the products is preferred because there is a sufficiently small difference between the speed of the stop and the input speed so that only little kinetic energy is released when the products hit the stop ,
