Definitions

  • the invention relates to a folder according to the preamble of claim 1.
  • a folder of this type is known from GB-A 1 036 778.
  • three transverse folding devices are provided, the two upset folding devices at the front in the transport direction being combined to form a unit and correspondingly attached to one another in such a way that the folding gap of the upset folding device at the rear in the transport direction simultaneously forms the inlet gap of the upset folding device in the transport direction. Accordingly, there is practically no distance between these two upsetting devices. There is therefore no possibility of delaying the products for the purpose of reducing the gaps between the individual products.
  • a distance bridged by a band guide is indeed provided between the flap folding device and the upset folding device at the rear in the transport direction.
  • the tape guide is formed in one piece here and therefore runs along the entire length at the speed of the flap folding device.
  • the subordinate upsetting device is therefore loaded inevitably at the speed of the flap folder.
  • This known arrangement therefore results in a very high stress on the products and thus a high risk of damage.
  • the one-piece tape guide ends at a distance in front of the inlet gap of the first upsetting device. Therefore, the products must inevitably be transferred from the belt guide to the inlet nip of the upsetting device in question, which is a major source of errors and faults, since in the area of such transfer points there is a risk of the products being without guidance, especially if comparatively small products are processed.
  • the folder 1 indicated by a dash-dotted outline is arranged in a manner known per se on the front face of a web-fed rotary printing press 2 also indicated by a dash-dotted outline.
  • a paper web 3 printed in the web-fed rotary printing press 2 is drawn over a funnel 4 fastened to the frame of the web-fed rotary printing press 2 to form a longitudinal fold.
  • pull rollers 5 forming the folder inlet are provided in the folder 1, the paper web 3 is divided into sheet-shaped products and here provided with two parallel cross folds.
  • the folder 1 is provided with a transverse cutting device 6 and two successive transverse folding devices 8 and 9, which are arranged downstream of the transverse cutting device 6 and are connected to one another by a band guide 7.
  • the finished two times Cross-folded products are thrown into a paddle wheel 10 arranged below the second cross-folding device 9 and are deposited by the latter in the form of a shingled stream on a delivery belt 11.
  • the cross-cutting device 6 consists, in a manner known per se, of a cylinder 13 provided with a knock-off knife 12, against which a further cylinder 15 is provided, which is provided with groove bars 14 assigned to the knock-off knife 12.
  • the first cross fold is designed as a flap fold.
  • the first transverse folding device 8, which is arranged downstream of the transverse cutting device 6, is accordingly designed as a flap folding device.
  • the cylinder 15 carrying the grooved beams 14 is hereby provided in a manner known per se with controlled folding blades 16 arranged between the grooved beams 14, which are arranged in a manner known per se with a jaw cylinder 17 placed on the cylinder 15 carrying the grooved beams 14 and folding blades 16 , controlled jaws 18 cooperate.
  • the structure and mode of operation of cross-cutting devices and flap folding devices are known per se and therefore do not require any further explanation in the present context.
  • This second transverse folding device 9 is designed as a compression folding device, which consists of a compression shaft 20, which practically forms a dead end for the products arriving via the belt guide 7, and of three with the same peripheral speed driven rollers 21, 22, 23, which are arranged and placed against each other, that on the circumference of the middle roller 22 offset by about 90 ° to each other, the input cross-section of the compression shaft 20 opposite transport gaps 24 and 25, in the area of which a take-along Products are produced, and a window 26, which is assigned to the upsetting shaft 20 and is opposite the middle roller 22 and is delimited by the two outer rollers 21 and 23, which are spaced on the circumference, in the area in which the products are not detected by the rollers 21 and 23, respectively .
  • the rollers 21 to 23 are driven so that the transport gap facing the first transverse folding device 8, here the transport gap 24 delimited by the rollers 21 and 22, acts as a feed gap into which the transport plane of the belt guide 7 arrives.
  • the two outer rollers 21 and 23 are adjustable to adapt the clear width of the transport gaps 24 and 25 and thus to adapt the transport gaps 24 and 25 to different product thicknesses compared to the central roller 22, as indicated in FIG. 1 by double arrows.
  • the diameter of the rollers 21, 22, 23 placed against each other in the area of the transport gaps 24 and 25 is such that between the two outer salts 21 and 23, which are offset by 90 ° from one another on the circumference of the middle roller, a larger one, forming the passage window 26 Distance results.
  • the compression shaft 20 connects to the middle roller 20 is open.
  • the compression shaft 20, which extends over the entire width of the machine, is inclined upwards from the window 26 forming its entrance with respect to the transport plane of the belt guide 7 entering the transport gap 24.
  • this inclination is approximately 45 °, ie the upsetting shaft 20, with its central plane continuing the transport plane of the belt guide 7, is approximately perpendicular to the axes 21 and 23 containing the axes of the two outer rollers 21 and 23 offset from one another on the circumference of the central roller 22 Level arranged.
  • the upsetting shaft 20 can be arranged exactly in the middle between the two outer rollers 21 and 23. In the exemplary embodiment shown, the upsetting shaft 20 is slightly offset relative to such a central arrangement in relation to the outer roller 23 assigned to the downward-pointing transport gap 25, in order to ensure a good entry and exit of the products.
  • the upsetting shaft 20 results as the interior of a configuration which is approximately U-shaped in longitudinal section and is open towards the middle roller, the parallel guide walls 27 and 28, which are spaced apart from one another and form across the entire width of the machine, and form the distance between them Guide walls 27, 28 bridging, limiting the depth of the compression shaft 20, also extending over the entire machine width stop web 29 is formed.
  • the upper and lower guide walls 27 and 28 are spaced apart from one another by an interposed spacer bar 30 arranged in the region of their ends remote from the roller and received on a crossbar 31 fastened to the machine frame.
  • the spacer bar 30 is interchangeable, which means an adjustment of the clear width of the compression shaft 20 to the makes the respective product thickness possible.
  • the guide walls 27 and 28 are tapered and bent to form a V-shaped inlet and outlet gap opening towards the middle roller.
  • the position of this second transverse fold depends on the depth of the compression shaft 20.
  • the stop web 29 delimiting the depth of the compression shaft 20 is accordingly adjustable over the length of the compression shaft 20. Normally, the stop bar 29 is set so that the center of the once folded Product is located above the transport gap 25 acting as a pull-out gap when the front product edge in the transport direction runs up against the stop web 29.
  • the tongue-shaped end near the roller of the upper guide wall of the upsetting shaft 20 extends far into the gap 24, which is facilitated by the fact that the upsetting shaft 20 is opposite the center between the two rollers 21 and 23 is offset toward the outer roller 23 associated with the transport gap forming the pull-out gap. It is therefore not possible to deflect the products in a direction leading away from the gap 25.
  • the spacing bar 30 which specifies the clear width of the compression shaft 20 is dimensioned such that no evasion perpendicular to the direction of transport is possible within the compression shaft 20.
  • the spacer bar 30 is accordingly interchangeable.
  • a further adaptation to the different conditions that arise in the case of products of different thicknesses is possible by pivoting or displacing the entire upsetting shaft 20.
  • the traverse 31 receiving the compression shaft 20 can simply be arranged so as to be pivotable or adjustable.
  • the guide walls 27 and 28, which extend over the entire width of the machine, can be designed as plate-shaped elements.
  • the guide walls 27, 28 consist, as can best be seen from FIG. 3, of tongues 34 which are arranged next to one another with a lateral spacing and which extend with their roller-side ends into the region of the two outer rollers 21 and 23.
  • the stop bar 29 has between the tongues 34 engaging tabs 35 which are attached to a bar 36 which is adjustably attached to one of the guide walls 27 and 28 respectively.
  • the tabs 35 engaging between the tongues 34 are simply formed in the exemplary embodiment shown as bent edge claws of the strip 36.
  • the tongues 34 of the lower guide wall 28 can be attached individually to the cross member 31, which in turn can be fixed on the machine frame of the folder 1.
  • the tongues 34 of the upper guide wall 27 can be combined to ensure a simple and quick interchangeability of the spacer bar 30 to form a continuous rake over the entire machine width.
  • the once cross-folded products are delayed in the area of the band guide 7 to such an extent that the gaps between successive products which result from the first transverse fold disappear except for a small remainder.
  • the rollers 21, 22, 23 of the upset folding device 9 can accordingly run at a speed which is lower than the peripheral speed of the cylinders of the flap folding device 8, so that the products entering the upset shaft 20 have a comparatively low speed, so that damage in the region of the stop web 29 does not increase fear.
  • the belt guide 7 has two successive sections 7a, 7b, which are interlocked with one another and are driven at speeds which are graded in the direction of transport, in such a way that the rear section 7a with the peripheral speed of the jaw cylinder 17 of the jaw folder 8 and the front section 7b the peripheral speed the rollers 21, 22, 23 of the upset folding device 9 run.
  • the tapes of the tape guide sections 7a and 7b are laterally offset from one another, that is to say arranged on a gap, so that mutual interlocking is possible.
  • the mutually adjacent deflection members of the band guide sections 7a, 7b are arranged behind one another.
  • the belts of the front belt guide section 7b are guided around the rollers 21 and 22 of the compression folder device 9 facing the flap folding device 8 and delimiting the transport gap 24 acting as a feed gap, whereby the belt guide-side transport plane automatically runs into the transport gap 24 and at the same time drives the belts of the front belt guide section 7b he follows.
  • the middle roller 22 is, as can best be seen from FIG. 2, provided with the grooves 37 assigned to the strips, the depth of which corresponds approximately to the strip thickness, so that in the region of the transport gap 25 acting as an extension gap, in the region of which the fold formation takes place, results in a practically smooth surface.
  • the lower belts of the front belt guide section 7b which wrap around the middle roll 22 of the upset folding device 9, are guided in such a way that they run off the roll 22 in the region of the second transport gap 25, which acts as a pull-out gap.
  • a deflecting roller 38 arranged below the roller 22 is provided.
  • the outer roller 23, which cooperates with the central roller 22 in the area of the transport nip 25, is likewise wrapped in belts 39, which are likewise guided over a deflection roller 38 arranged below the roller 23 and accordingly run off the roller 23 in the area of the transport nip 25.
  • FIG. 1 A downward ejection section 40 can be seen, which throws the twice cross-folded products into the paddle wheel 10 arranged below it.
  • the rollers 21, 22, 23 of the upset folding device 9 are provided with drive wheels 21a, 22a, 23a which are arranged in the region of a machine side and are designed here as toothed wheels and which engage with a double-sided toothed belt 41.

  • the upper and lower belts of the front belt guide section 7b are driven by the rollers 21 and 22, respectively, of the compression folding device which they wrap around. The same naturally also applies to the belts 39 that wrap around the roller 23. As shown in FIG.
  • the upper belts of the rear belt guide section 7a wrap around the region of the folding jaw cylinder 17 upstream of the lifting tongues 19 and thereby receive a drive at the desired speed. Only the lower belts of the rear belt guide section 7b accordingly require a separate drive.
  • a deflection roller 43 assigned to these belts is provided with a laterally attached drive wheel 43a which is in engagement with a toothed belt 44 which is arranged coaxially to the pinion 42 and has a larger diameter than the desired speeds Pinion 45 is driven.
  • the twice cross-folded products are laid out. But it would also be conceivable this is fed via a further band guide, which can be formed in one piece or in the above-described manner also in two parts, to a further transverse folding device, for example designed as an upset folding device.
  • the embodiment according to FIG. 4 offers the possibility of laying out cross-folded products only once.
