Definitions

  • the invention relates to a device for conveying printed sheets in a channel bottom and a guide element extending on a longitudinal side conveying channel, in which fixed at a circulating in the conveying direction traction means at regular intervals, the sheet conveyors are arranged transporting.
  • Devices of the type mentioned are used for transporting and collecting printed sheets to loose book blocks in gathering machines.
  • investors are arranged, which feed the conveyor channel in each case with a variety of printed sheets to be collected.
  • the cross-sectional profile of the conveying channel is L-shaped and consists of an approximately vertical guide wall and a sloping towards this channel bottom.
  • the channel bottom is divided into two by the conveyor track of engaging in the conveyor channel driver separate floor elements.
  • the drivers are attached to a circumferentially driven traction means at equal intervals and push the sheet material compositions in the conveyor channel.
  • Each driver is fed on its way in the conveyor channel of each feeder a sheet so that each driver is associated with a book block composed of loose sheet at the end of the collection.
  • the channel bottom is inclined towards the guide wall, so that the sheet material combinations rest by gravity on the guide wall and can not be rotated by acting in the region of the channel bottom frictional forces.
  • the two parts of the channel floor are in a shallow resp. obtuse angles to each other, whereby the sheet material combinations are slightly bent parallel to their conveying direction.
  • the kink has the task of stiffening the per se labile printed products in their conveying direction in the region of the force application by the driver.
  • a conveyor channel according to the prior art is for example in the CH 446 269 disclosed.
  • a disadvantage of such devices is that most sheets have at the rear edge on which attack the driver, a fold, which stiffens the sheets so that they can no longer bend by the weight transversely to the conveying direction.
  • the previewed US Pat. No. 4,795,144 relates to a gathering device for signatures, comprising a conveyor with spaced-apart dogs projecting into a conveyor channel fed with signatures from feeders arranged along the conveyor channel to form loose printed products.
  • the conveyor channel has a second wing portion disposed at an angle to a first wing portion, the wing portions being spaced apart.
  • the two angles of the second wing part of the conveying channel is greater than the angle of the first wing part with respect to the horizontal BDh that the two Traghalteamaschine viewed in the transverse direction of the conveying channel form a kink, which in the longitudinal direction of the conveyor channel on the printed sheet respectively. collated printed sheet affects.
  • the object of the invention is to provide a device of the type mentioned so that both light, flexible and bulky sheets can be processed reliably and accurately.
  • the channel bottom has an at least partially concave-shaped, continuously curved surface.
  • the Fig. 1 shows a section of a conveyor 1 for the purpose of collecting resp. Collating sheet 2 to Bogerunaterialzusammengna 7 resp. Book blocks.
  • the conveyor 1 successors 3 are arranged one behind the other, each store a next sheet 2 on the sheet material assemblies 7.
  • On the way of the conveyor 1 is before each driver 12 of the investors 3 each a sheet 2 placed on the sheet material compilations 7 so that at the end of the conveyor 1 complete sheet material compilations 7 are present, which are transferred for further processing in a next machine, such as an adhesive binder.
  • the driver 12 mounted at equal distances on the traction means 11 and with this a conveyor member 20 forming the sheet material assemblies 7 in the conveying direction F in the formed from the channel bottom 10 and a guide member 5 conveying channel 14.
  • the channel bottom 10 is through a recess for the web of the driver 12 divided into a guide element 5 facing bottom element 8 and another bottom element 9.
  • Both bottom elements 8,9 are connected to one another by a yoke 22 guided in a holder 23 and can be adjusted in the longitudinal direction of the guide element 5, transversely to the conveying direction, by means of a height adjustment device 15, for example a lifting spindle.
  • the guide element 5 in an alternative position (in Fig. 2 dashed lines) displaceably mounted by a pivot bearing 24.
  • Other bearings, such as linear bearings or combinations of bearing types are also conceivable.
  • in particular adjustments can be made or faulty sheet material assemblies 7 are removed from the conveyor channel 14 in case of faults.
  • the channel bottom 10 can thus be optimally optimally adapted to the level of the uppermost signature of the sheet material assemblies 7 with respect to guide element 5.
  • a slidably guided on the bottom member 8 is elastic Element 18 is provided, which is pressed by a spring system 19 against the guide member 5.
  • the bottom element 8 forms with the guide element 5 an angle ⁇ of a maximum of 90 °.
  • the sheet material assemblies 7 are with their flat sides on the preferably against the guide member 5 towards inclined channel bottom 10 and stand with the edges by the inclination of the guide member 5 at.
  • the channel bottom 10 has a conveying channel facing, advantageously arcuate, concave cross-sectional shape on which create the sheet material assemblies 7. On the one hand, this leads to a stiffening of the printed sheets 2 in the conveying direction F and, on the other hand, the respectively uppermost printed sheets 2 of the sheet material assemblies 7 are pressed against the underlying printed sheets 2 by an internal restoring force due to the imposed deformation, especially in the region of the back edge 16 and the front edge 17.
  • the continuously curved, concave shape of the channel bottom 10 further leads to a uniform distribution of the contact force on the channel bottom 10 and thus to a favorable distribution of frictional forces in relation to the turning of wide sheet material combinations 7.
  • a further advantageous embodiment of the inventive device results from in the channel bottom 10 built Blas Kunststoffdüsen 13 which produce an air cushion in the conveyor channel 14 between the channel bottom 10 and the sheet material compositions 7 sliding thereon.
