Definitions

  • the invention relates to a method for combining two shingled streams running side by side, in particular consisting of folded products, into a common product stream and, according to a further inventive idea, relates to an apparatus for carrying out this method.
  • the folding products produced in a folding device and designed in the form of one or more shingled streams are generally subsequently fed to a packaging device in order to form dispatchable units.
  • a packaging device in order to form dispatchable units.
  • the procedural solution to this problem is, according to the invention, that the two scale streams have a displacement of their products corresponding to half a scale distance in the running direction, brought together in a common transport plane at an acute angle to a complete overlap and alternately in the area of the meeting of the mutual products from the common one Transport level can be deflected.
  • the two shingled streams to be combined are advantageously pushed together to form a common shingled stream with half the shingled spacing, a trouble-free pushing together being achieved due to the mutual displacement of the two shingled streams in the running direction and due to the alternating deflection of the successive products between the two shingled streams.
  • the end product is advantageously a uniform stream of flakes with the same products.
  • this common scale flow has a comparatively high stability, which has a positive effect on the further processing, for example in a packing device. Nevertheless, this ensures that all products in the area of the combined stream flow have the same position and orientation, which is often desirable for reasons of sorting.
  • the measures according to the invention ensure gentle treatment of the products, since they practically do not leave their original transport level. From this it can be seen that the invention solves the task set with simple and inexpensive means.
  • a further expedient measure can consist in the removal of the product stream combined to form a shingled stream in a direction corresponding to the course of the bisector between the directions of the two shingled streams to be combined. This measure advantageously facilitates the alignment of the front product edges perpendicular to the end direction.
  • the two shingled streams to be combined can be non-positively detected at least in the area of their outer side edges and can be guided while maintaining the non-positive engagement until the products of the two shingled streams are only laterally offset from one another by the respective non-positively captured area.
  • two shingled flow guides inlet branches 1, 2) converging in a V-shape and having the same speed in the transport direction
  • the end regions (ia, 2a) having the same transport planes are designed in the manner of a miter symmetrical to the bisector between their transport directions and in the area of the intersection of the inner peripheral edges of the shingled streams (4 or 5) lying on them have a support-free area (14, 14a) to which a deflection device (15 or 15a) arranged above the inner edge edges of the shingled streams (4 or 5) is assigned , by means of the edge region of the successive products (13) of the two shingles (4 or 14) corresponding to half a shingle spacing (S) in the direction of travel of their products (13, 14a) of the shingled flow guides (1, 2) 5) can be lowered from the original transport level .
  • the table provided here advantageously provides reliable, level support for the two streams of shingles in the overlap area.
  • the table recess and the deflection device assigned to it With the help of the table recess and the deflection device assigned to it, the formation of insertion gaps located in the transport plane for mutually pushing the products of the two scale streams into one another is achieved despite this fixed support.
  • the recess provided in the region of the table advantageously ensures that the shingled flow region which is unsupported in the region of the recess can be deflected from the transport plane in the desired manner simply by gently pressing it down, which proves to be particularly advantageous when processing multilayer folded products.
  • the measures according to the invention accordingly result in a high degree of reliability and functional reliability with a comparatively simple construction.
  • the deflection device can be designed as a cam disk arranged above the table, driven in time with the incoming products and engaging with its circumference in the recess of the table. In an advantageous manner, this is a very robust, continuously drivable component for depressing the scale flow areas going beyond the table recess. If only one cam disk is provided, it is expediently arranged in such a way that its plane of rotation corresponds to a plane perpendicular to the table and running along the bisector between the two shingled flow guides converging at an acute angle. This ensures that the circumferential cams of the cam disk alternately come into engagement with one or the other shingled stream offset in the running direction.
  • a further advantageous measure can consist in the fact that the shingled flow guides each have at least one pair of clamping bands which detects the outer edge of the respectively associated shingled flow and extends beyond the clamping gap and runs parallel to the assigned transport direction.
  • a further advantageous measure can consist in the fact that, following the pair of clamping bands assigned to the outer marginal edges of the two shingled streams, alignment bands are provided which run parallel to this and are arranged perpendicular to the table plane, preferably with lead. are driven relative to the pair of clamping bands.
  • These alignment belts straighten the individual products of the combined stream of shingles. H. with its front edge perpendicular to the end running direction, which advantageously corresponds to the course of the bisector between the transport directions of the two shingled streams to be combined with one another.
  • the scale flow delivery according to the invention is, as can best be seen from FIG. 1, a top view of a Y-shaped scale flow guide with two inlet branches 1, 2 converging at an acute angle in the transport direction and a direction corresponding to the course of the bisector between the transport directions of the inlet branches Discharge branch 3 based.
  • the outlet-side ends of the inlet branches 1, 2 overlap each other, so that the shingled streams 4 and 5 arriving on the outlet branches 1, 2 are pushed together to form a common shed stream 6, which is transported away on the outlet branch 3.
  • the inlet branches 1, 2 and the outlet branch 3 are formed by sets of belts which run in the respective direction indicated by arrows and are arranged in accordance with the desired Y-shaped basic configuration and are driven synchronously at the same speed.
  • the outlet branch 3 has a plurality of belts 7 arranged next to one another in order to achieve reliable support.
  • the respective outer bands 8a go through to the end of the overlap region.
  • the inner bands 8b already end in the area where the two inlet branches 1 and 2 begin to overlap.
  • the products forming the shingled streams 4, 5 are supported in this area by means of a table 9 formed by a plate of sheet metal or plywood or the like, over which the upper run of the outer bands 8a and the inner bands 8b partially passes.
  • a clamping gap 10 is provided in the area of each inlet gap 1, 2, in which the corresponding products with their outer, ie. H. shrink away from the edge.
  • a pair of clamping bands is provided in order to form the clamping gap 10, which is effected by forced movement and transport, which is simply formed here by the respective outer band 8a as the lower band and by an upper clamping band 11 associated therewith, which extends approximately over the length of the table 9 .
  • the belts 8 and 7 forming the inlet branches 1 and 2 and the outlet branch 3 are forcibly driven, with at least the belts 8 of the inlet branches 1 and 2 having the same speed.
  • the belts 7 of the outlet branches should also have the same speed as the belts 8 of the inlet branches 1, 2.
  • the products forming the shingled streams 4, 5 to be combined may be cardboard blanks or the like.
  • these are supposed to be folding products 13 which are designed by a folding apparatus arranged downstream of a printing press.
  • two shingled streams are already designed to reduce the working speed.
  • interlocking products in the form of a simple shingled stream and then pulling the products apart to such an extent that two parallel shingled streams result.
  • there are equal scale spacings the scale streams 4, 5 to be combined with one another are guided in such a way that the fold back of the fold products 13 points in the direction of transport in the overlap region.
  • the shingled streams 4, 5 to be combined with one another are offset from one another in the transport direction by about half a shingled spacing, so that the folded products 13 of the two shingled streams 4, 5 in the region of the intersection of the inner marginal edges of these two shingled streams, i.e. H. meet at the beginning of the mutual overlap, with an offset corresponding to half a scale distance, d. H. the inner front corner of the folded products 13 of the one shingled stream meets the side edge of the respectively associated folded product 13 of the opposite shingled stream approximately in the region of the center of the shingled distance.
  • the scale spacing of the combined scale stream 6 accordingly corresponds to half the scale distance of the scale streams 4, 5 to be combined.
  • the inner marginal edges of the successive products of the two scale streams 4, 5 are alternately deflected downward from their transport plane defined by the table 9.
  • the table 9 is in the area of the intersection of the inner marginal edges of the two scale streams 4, 5, d. H. in the area of the beginning of the mutual overlap of the two inlet branches or the shingled streams associated therewith, i.e. in the area in which the folded products 13 of the two shingled streams 4, 5 meet, are provided with a recess 14 into which one is rotatably mounted above the table 9
  • Cam disk 15 dips with its circumferential cams 16, as can best be seen from FIG. 3.
  • the recess 14 can, as shown in Figure 1, be rectangular and be arranged so that the bisector between the inlet branches 1, 2 converging at an acute angle forms a line of symmetry.
  • the plane of rotation of the cam disc 15 corresponds to a perpendicular to the table 9, the aforementioned bisector containing level.
  • the cam disk 15 is provided with a plurality of tooth-shaped cams 16, the spacing of which corresponds to half the scale spacing in the area of the inlet-side scale flows 4, 5.
  • the cam disc 15 is in time with the incoming products, i. H. driven so that each of the folded products 13 of the two shingled streams 4 passing underneath them comes into engagement with a circumferential cam 16.
  • the edge regions 18 of the recess 14 can be angled slightly downwards to protect the products to be pressed down.
  • a center ie. H. provided in the region of the bisector 15 which alternately depresses the successive products of one or the other scale flow.
  • two cam disks arranged next to one another, each of which presses down the folded products i3 of the respectively associated shingled stream at an offset cycle. These cams could be arranged on a common shaft and driven at the same speed.
  • the distance between the circumferential cams provided would correspond to the scale spacing in the area of the inlet-side scale flows 4, 5, the circumferential cams of the two cam disks being offset from one another by half a scale spacing.
  • the front edges or side edges of the folded products 13 are at right angles or parallel to the end direction, ie. H. aligned with the direction of the outlet branch 3.

  • the alignment belts 19 have a grippy outer surface and are driven at a somewhat higher speed than the transport speed, so that the from the clamping bands 11 released folding products 13, each of which still have the orientation predetermined by the clamping bands 11, are pivoted in such a way that their front edges are oriented approximately perpendicularly and their side edges approximately parallel to the running direction of the outlet branch 3.
  • the aligning belts 19 are expediently arranged so far outside that their running surfaces practically only come into engagement with the front corners of the folded products 13 to be pivoted.
  • the aligning belts 19 are followed by a vibrating device with vibrating bars 20 running parallel to the side edges of the outflow-side scale flow 6, which can be displaced in a shaking movement perpendicular to the transport direction of the outflow-side scale flow 6, as indicated by the double arrows shown in FIG. 1 is.
  • the aligning belts 19 aligned parallel to the edge edges of the respectively assigned inlet branch 1 or 2 thereby practically constitute an inlet funnel bridging the fork-shaped transition from the two inlet branches 1, 2 to the outlet branch 3 for the vibrating ledges 20 running parallel to the edge edges of the outlet branch 3 Shaking device represents.
