Definitions

  • the invention relates to a device for pulling apart sheets which are offset with respect to one another transversely to the transport direction, preferably of folded products transported in the form of a scale track over a transport route, with folded products arranged in the region of a section of the transport route on both sides of the product track, with the free edge of the respective facing offset Sheets which can be brought into engagement and are driven with the same holding device running in the transport direction, at least one of which also has a movement component running transversely to the transport direction.
  • a device of this type is known from DE-PS 2 417 614. Since, in devices of this type, two folding products of the same or different thickness can be folded together and possibly trimmed, a second or a double-width folding device is unnecessary.
  • the holding devices are designed as gripper rows which are each guided on an endless track and have grippers arranged next to one another, which grasp a respectively assigned sheet package at its free edge formed by the mutual offset and bring it into the desired lateral position.
  • the disadvantage here is that the predetermined distance between the grippers requires a precise distance between the successive folding products.
  • the grippers have a fixed mutual distance.
  • each holding device which also has a movement component running transversely to the transport direction, as a band guide with its front end protruding laterally in relation to the transport direction and having a straight edge strip formed by the facing, offset by the sheet offset of the product web is formed through the clamping gap, which is delimited by mutually opposite, uniformly rotating clamping bands.
  • each clamping gap on the side is delimited by at least two clamping bands rolling on one another advantageously results in an elastic, gap-free limitation of this clamping gap over its entire length and thus not only a particularly simple construction but also a particularly high degree of freedom from interference.
  • the advantages that can be achieved with the invention can therefore be seen in particular in their simplicity and therefore overall in excellent economy.
  • the clamping bands can advantageously be supported by pressure rollers arranged in the area between their deflection devices.
  • the opposing pressure rollers of the lower and upper clamping band of a band guide can advantageously be offset from one another in the transport direction in order to ensure high elasticity in the region of the clamping gap. This ensures that thickenings in the area of the product flow can also be absorbed without disruption and readjustment.
  • a further advantageous embodiment of the superordinate measures can consist in the fact that at least one clamping band, preferably all clamping bands of each band guide, are designed as toothed belts received on toothed belt wheels. These measures result in a non-slip
  • the upper and lower clamping bands of each band guide can advantageously be connected to one another in terms of drive by means of a countershaft arranged in the region of a toothed belt wheel pair.
  • the folding product 1 shown in FIG. 1 consists of two interlocking sheet packs 1a and 1b, which are laterally offset from one another, so that in the area of each side there is a free edge 2 with which one sheet pack projects above the other.
  • the width of the edge 2 corresponds to the lateral offset.
  • the two sheet packs 1a and 1b can be grasped and pulled apart, so that two separate folding products result, which can have the same or different number of pages.
  • the production of these two folding products can, however, be carried out together in one folding device, the working width of which corresponds only to the width of a product plus the lateral offset.
  • the structure and mode of operation of a folder are known per se and therefore do not require any detailed explanation in the present context.
  • the folded and possibly trimmed folding products are, as can be seen in FIG. 2, deposited by a paddle wheel 3 in the form of a shingled stream 4 on a delivery belt 5, which consists of carrying belts 7 which are guided around belt rollers 6 and are laterally spaced apart.
  • the belt rollers 6 can simply be mounted in the side walls 8 of the folder.
  • the delivery belt 5 leading out of the folder forms the first section of a multi-part transport route leading to a further processing device, for example to a packaging device.
  • holding devices are provided on both sides of the shingled stream 4, which hold the passing folding products at the respectively assigned free edge 2 and transport them further in the direction of transport and from one another separate, ie pull apart sideways.
  • Belt rollers are also provided to accommodate the conveyor belts 7 forming the transport route section 9 and the further transport route sections.
  • a common belt roller can be provided in the toothing area of successive transport route sections, on which the carrying belts 7 of successive transport route sections are lined up in an alternating sequence, which automatically results in a drive-related connection of the individual transport route sections.
  • At least one upper and one associated lower clamping band 10 and 11 are provided, respectively, web guides 12 and 13, each of which delimit a straight, continuous clamping gap 14, which extends over its entire length and which faces from the respective one , through the relevant edges 2 formed edge strips of the scale web 4 is penetrated.
  • the two web guides 12 and 13 can be extended laterally with their front end opposite to the transport direction indicated by the arrow 15.
  • the one web guide 12 is arranged parallel to the transport direction and only the other web guide 13 with its front end at a certain angle relative to the transport direction is flared.
  • the length of the web guides 12 and 13 and the size of the opening angle are chosen so that a complete separation and a sufficient distance between the separated products are achieved even with the maximum product width.
  • the maximum product width corresponds to the working width of the upstream folder minus the width of the smallest required offset. If the product width changes, only the width of the offset is expediently changed, so that no lateral adjustment of the web guides 12 or 13 is necessary.
  • the web guides can therefore be arranged stationary. However, it would also be conceivable to provide lateral adjustability. For this it is sufficient if only the web guide 12 parallel to the direction of transport is arranged to be laterally adjustable.
  • the clamping bands 10, 11 forming the web guides 12 and 13 are driven by the folder.
  • the drive takes place via the conveyor belt 5, which is driven in a manner not shown here.
  • the lower clamping belt 10 of the web guide 12 parallel to the transport direction is accommodated on the belt rollers 6 assigned to the adjacent carrying belts 7, of which the belt roller at the rear in the transport direction also belongs to the delivery belt 5 .
  • the upper clamping band 11 is received on band wheels 18 arranged above the band rollers 6.
  • the drive coupling with the assigned lower clamping band 10 takes place, as can best be seen from FIG. 4, via spur gears 19 arranged on laterally projecting drive stubs 19.
  • the clamping bands 10 and 11 of the laterally flared web guide 13 are on in the area between the web rollers 6 Transport route section 9 arranged band wheels 20 which, as shown in FIG. 5, are also drivingly coupled to each other by spur gears 21 placed on laterally projecting drive stubs.
  • the torque is introduced via a cardan shaft 22, which is connected to the front belt roller 6 of the delivery belt 5 by means of a countershaft arranged here laterally outside of the web guide 12.
  • a toothed belt 23 is provided for this purpose, which is received on a toothed belt pinion 24 on the belt roll side and a toothed belt wheel 25 mounted parallel to the axis thereof.
  • the clamping tapes 10 and 11 can be designed as simple tapes similar to the support tapes 7. In order to achieve a smooth running of the clamping bands 10 and 11, they should be designed as toothed belts in the exemplary embodiment shown, which in a simple manner achieves exact synchronism of the clamping bands. This ensures that there is no relative movement of the clamping bands relative to the products detected on the edge, so that they are protected.
  • the belt wheels 18 and 20 are designed in this case as toothed belt wheels.
  • the belt rollers 6 are provided with the clamping belt 10, which is accommodated thereon and assigned to the web guide 12, toothed belt pinions 26.
  • the web guides 12 and 13 can each be formed by aligned individual bands or multiple bands.
  • 12 individual belts are provided to form the web guide.
  • Double belts are provided to form the web guide 13.
  • pressure rollers 27 are provided in the area between the deflection devices assigned to the clamping bands 10 and 11, as can be seen in particular in FIGS. 2 and 6, which support the effective engagement strand of the respectively assigned clamping band, so that over the entire length of the Clamping gap 14 reliable sheet entrainment is guaranteed.
  • the pressure rollers 27 assigned to the lower clamping band 10 and the respectively associated upper clamping band 11 are offset with respect to one another in the transport direction, so that a certain elasticity is retained in the region of the clamping gap 14, which thus also copies of stronger material or thickening of the scale flow without damaging the drive means and can record without readjustment, which ensures trouble-free transport.
  • the distance between the toothed belt wheels 18 can be adjustable to accomplish any length compensation that may be required. In the exemplary embodiment shown, one or both toothed belt wheels 18 should simply be arranged correspondingly resiliently. When processing shingled streams with a thickness that differs greatly from one another, it may be expedient to arrange at least the upper and / or the lower pressure rollers 27 in an adjustable manner.
  • An inlet or outlet gap may result in the area of the belt deflections.
  • the pressure rollers 27 are freely rotatably received on side cheeks 28, which in turn are fastened to holders 29 fixed to the housing.
  • bearing blocks 30 arranged on a carrier plate 31 are provided.
  • the carrier plate 31 is pivotally attached to the folder side walls 8 by means of holders 32 and rests on the floor via supports 33.
  • the toothed belt wheel 25 connected to the cardan shaft 22 can simply be found in egg ner projection of the adjacent bearing block 30 may be mounted.
  • the holders 29 assigned to the cheeks 28 are also fastened on the carrier plate 31.
  • the transport route section 9 adjoining the transport route section 9 having the lateral web guides 12 and 13 is positioned so close with its rear belt roller 6 to the front belt roller 6 of section 9 that there is a smooth transition.
  • the side supports 34 of section 17 can be releasably attached to the adjacent bearing blocks 30.
