Definitions

  • the present invention relates to a device and a method for transporting flexible, flat products according to claim 1 or 13.
  • the printed products are often transported by means of staple transporters. It often happens that the printed products for further processing of the staple transporters are delivered to the belt conveyor, see, for example US 4,565,363 A1 or EP 1 493 701 A1 .
  • the transfer of the printed products from the staple conveyor to the belt conveyors has the problem that they flutter and, in particular, become restless after being released by the clamps of the staple transporters and there is a risk that they will lose their ordered position.
  • the clamps of the staple transporter are intended to hold and transport with their clamp mouth a flexible, flat product, in particular a printed product such as a newspaper, a magazine or the like, at its holding area adjacent to a holding edge. Since the products are held in the clamp mouth, they have a well-defined position.

  • the course over the entire transfer section is arcuate.
  • the brackets can each be equipped with a single product. However, it is also possible that the brackets are equipped with more than one product, for example two products, which products are arranged in a scale, so that the holding areas of the products are exposed.
  • the belt conveyor is designed as a vacuum belt conveyor with a perforated belt, the active strand runs in the transfer section at a distance from the path of movement of the Klammermäuler.
  • the arcuate course of the path of movement of the Klammermäuler causes the products with their free, the retaining edge facing away from the end, safely reach the active run of the vacuum belt conveyor to the plant.
  • the vacuum belt conveyor sucks the end area of the products in question on the active strand, stabilizing them and keeping them in a defined position. so that they can not change this situation when you subsequently open the clip in question.
  • the trajectory of the Klammermäuler has a curved course and the active run of the vacuum belt conveyor runs in the transfer section at a distance from the trajectory, the mutual distance of the products, or their overlap, is changed during the transfer. If the arcuate course of the movement path is convex, the distance between the free ends of successive products opposite the holding edges of the products is increased. Accordingly, this distance is reduced in a concave course.
  • Vacuum belt conveyors have at least one self-contained perforated belt, which is driven circumferentially in the conveying direction and whose holes are connected in the suction section of the active strand with a vacuum source.
  • the suction section can extend over virtually the entire length of the active strand. However, it is also possible for the suction section to be subdivided in successive subsections in the conveying direction.
  • vacuum belt conveyors are provided with a negative pressure trough connected to the vacuum source via the opening of which the active strand of the perforated belt is moved.
  • a negative pressure trough connected to the vacuum source via the opening of which the active strand of the perforated belt is moved.
  • the Klammermäuler have in the transfer section on a speed - amount of its vectorial speed - on, which according to the invention is smaller than that Speed - and thus the speed of rotation - of the perforated belt.
  • the active strand preferably has a course which is at least approximately curved in the same direction with respect to the movement path. At least approximately arcuate course means that the sheet can also be reproduced by successive, chord-like sections.
  • the path of movement of the clamp mouths in the transfer section and preferably over the entire length of the transfer section has a circular arc-shaped course.
  • the distance between the trajectory of the Klammerffleuler and the active run of the vacuum belt conveyor is adjustable. This allows optimal processing of differently thick and different lengths of printed products.
  • the respective clamp jaws forming clamping tongues of the clamps, and thus the Klammermäuler, about a transverse to the conveying direction, in particular perpendicularly extending bracket axis pivotally mounted.
  • This makes it possible, for example by means of a link control, to control the desired pivoting position of the clamp mouths upon reaching the transfer section and within this.
  • the staple axis runs parallel to the conveying surface defined by the vacuum belt conveyor.
  • the clamp mouths are directed obliquely backwards with respect to the conveying direction. As a result, the free end edge of the products is trailing with respect to their located in the clamp mouth retaining edge.
  • the staple conveyor on a guided in a guide channel conveying member.
  • This is preferably a link chain, which can be claimed on train and pressure.
  • cantilever-type support members are arranged in a predetermined carrier distance, which pass through the gap of a C-shaped cross-section having guide channel. These carry outside the guide channel in each case a clip.
  • the exact position and location of each product and thus the position of the products to each other is always predetermined and known.
  • the path of movement of the clamp mouths is convex and corresponding to the active run of the vacuum belt conveyor concave.
  • the centrifugal forces can be utilized, which press the free end region of the products in contact with the active run of the vacuum belt conveyor.
  • the distance between the free end edges of the successive products will be greater than the carrier spacing and thus the distance which these end edges occupy in a rectilinear course of the staple transporter, additionally enlarged.
  • the active strand in the transfer section is subdivided into rectilinear segments which follow one another in the conveying direction and thus form chords of the sheet, allowing a concave course of the active strand in the transfer section.
  • This embodiment offers the possibility to hold the perforated belt with respect to the arc in the radial direction to the outside between successive segments.
  • At least some of the segments are associated with a negative pressure well connected to a vacuum source over which the active run passes. At least the segments located in the suction section of the vacuum belt conveyor are formed in this manner. Preferably, all, possibly except in the conveying direction, the first or the last segment, executed in such a way.
  • the perforated belt between each successive segments Q-shaped guided around guide rollers. This allows a low-friction operation.
  • the perforated belt in a preferred manner, is supported in the area of the vacuum troughs by means of support rollers against moving into the vacuum troughs.
  • the vacuum belt conveyor has, in addition to the perforated belt, at least one further perforated belt driven at the same speed, preferably on both sides.
  • the Segments of the further perforated belt or of the further perforated belts are preferably offset relative to the segments of the perforated belt in the conveying direction, so that the area between successive segments of the perforated belt is bridged by a segment of the further perforated belt or the further perforated belts. This ensures uninterrupted holding of the end regions of the products despite segmentation of the active strand.
