  • the invention is based on a fluid transformation of a scale-like formation of flexible, flat objects, in particular folded printed sheets by means of a conductive agent.
  • a fluid transformation of a scale-like formation of flexible, flat objects in particular folded printed sheets by means of a conductive agent.
  • the printed products to be processed are preferably supplied in the form of an imbricated flow, in which the trailing edges, in folded sheets whose fold, the printed products or printed sheets to be processed are arranged above and overlap the subsequent printed product.
  • Such a scale flow is fed to the conducting means, which serves to transform the scale flow in angle, orientation and density, so that a new scale-like formation results.
  • the supplied printed products are arranged as a stack, layer or imbricated stream, they are transferred before being separated by suitable means into said scale-like formation standardized according to the invention.
  • the fold is preferably arranged at the top and the folded sheet supported on its flower, so that the folded sheets can be detected at the fold individually or in a defined number.
  • the invention accordingly also makes it possible to process a bar, a stack or other formations using the same method according to the invention for separating the printed products, ie that the products do not necessarily have to be supplied as scale flow.
  • the standing products for example, a rod are thus transferred to the desired oblique position, whereas in a scale flow, as described above, an erection of the printed products is required.

  • the device according to the invention enables dynamic processing of the printed products.
  • the invention may also include a passive removal, that is, the separation or separation takes place by the transfer module itself and the separated sheet or sheet groups are transferred to a removal unit, which plays no separating function.
  • the functional principles known today require that the printed products are transferred practically horizontal or supported in a planar manner.
  • the printed products are oriented by the conductive agent so that they are present in the transfer region of the guide surface in an obliquely upright, largely freely accessible position and separated.
  • this also has the advantage that the separation process does not necessarily mean that a printed product must be completely separated before the separation of the next printed sheet can begin.
  • the fold points upwards, ie away from the guide surface, so that the printed sheets are delivered individually or in a defined number by means of e.g. a gripping means can be detected easily and with high accuracy.
  • the printed products show in processing with each other and with the Leitsch a procedurally favorable mutual influence and stabilization, which is particularly relevant in the end of the baffle for the process.
  • a plurality of adjacent printed products show in their entirety an elastic or supple behavior.
  • a first form of elastic behavior can be observed in a package of printed products that is leveled and held by stops. As the constraints of the printed product package are pulled apart longitudinally, the angle between the printed products and the plane becomes flatter. By contrast, pushing the bounds of the package together makes the angle between the plane and the printed products steeper. This behavior, understood in this way, is elastic.
  • Another form of elastic behavior is particularly important in an arrangement of folded printed products. Due to the fold, the individual printed products tend to bulge in regions or to open. But even with other flexible products or printed products due to material irregularities and air entrapment such flexibility is given.
  • This buffering effect acts as a dynamic buffer (due to local compression) to a certain extent and geometrical compensation during processing. This effect is specifically exploited here to compensate for differences in processing speed between feeding and discharging device means or short term disturbances.
  • the guide surface used in the conducting means preferably has a shape which causes the scale-like formation guided over it to be compacted by printed products and simultaneously set up (or tilted) in a controlled manner.
  • Particularly suitable are guide surfaces having a flat portion, which merge into an arcuate or straight, obliquely downwardly extending portion.
  • the baffle e.g. in the form of a mechanical stop preventing the printed products of the compacted scale flow from passing along the guide surface.
  • the printed products are controlled jammed and erected.
  • the lateral gravity decreases continuously, so that the printed products come into an unstable equilibrium and then tend to tipping over.
  • they enter the effective range of a conveyor, which captures them and leads them away one by one.
  • a special separating device may be included here, which transfers the printed sheets to a subsequent conveying module.
  • a means for actively changing the inclination of the printed products in order to convey the printed products in a controlled manner to the conveyor at the moment they tend to tip over.
  • This may be, for example, a rotating, flat or structured roller or a rotating cam belt, by means of which the printed products are influenced by friction, form or other adhesion.
  • rollers or vane-type wheels equipped with suction elements which intervene between the printed products and thus bring them dynamically to the conveyor are also suitable.
  • a controlled air flow acting from the side or from the top to the printed products is also suitable.
  • transfer means or separating means has a lever, at one end of a suction cup is attached.
  • the lever is rotatably mounted about an axis, wherein the pivot point of the axis is arranged in the region of the mechanical stop at the end of the guide surface.
  • the foremost printed product, which is present at the mechanical stop (board) is pressed against the lever or the suction cup.
  • the lever and with it the printed product held by the suction cup is pivoted relatively quickly, so that the printed product is free and can be detected by the conveyor.
  • the remaining printed products remain stationary due to their inertia or held by a mechanical stop. It is readily possible to effect the removal or the conveying away also by circulating roller pairs, conveyor belts or alternative conveying means.
  • the distance between the guide surface and the conveyor, or the transfer means is preferably adjustable, so that the device is suitable for the processing of printed products of variable formats.
  • a further advantage of the invention is that a switch system can be provided at the location of the separation and, if necessary, so that the printed sheets can be transferred to different conveyors immediately after the transfer module or can be removed therefrom.

  • additional active means for controlling the flow, density and shape of the scale flow.
  • These conductive agents are e.g. around one or more circulating conveyor belts (conveyor belts), which act by means of friction on the flow behavior and transfer of the printed products.

  • An additional advantage of the invention is that, especially with folded sheets in the area of the flower, greater compression is produced than in the middle or at the folded edge of the folded sheets. The folded sheets have a tendency to expand in the middle region, so that the folded edges are not tight against each other, but can be processed in a slightly fanned out formation, which in particular simplifies the separation and the already described folding.
  • the embodiments described above have a board 3, which is directly connected to the guide means.
  • the required stop according to the invention but also by a separate means, for example.
  • a movable plate or stop bars are formed.
  • a movable stop is indicated, which is moved controlled in the direction of arrow M when removing a sheet, so that the foremost printed products can also be given free on the flower side and thus easily removed.
  • the removal device according to the embodiment FIG. 5 has a conveyor, with which the printed products are conveyed away substantially immediately after the separation (not shown here) and the removal in the direction of the arrow H substantially vertically upwards.
  • the board 3 or the stop can also be formed by movable elements which promote the printed products in the removal direction, so that the removal process is supported in this way.
  • the expert will provide, inter alia, a horizontal axis, optionally controlled rollers, which minimize or avoid any frictional forces of the product to be removed relative to the board 3.
  • the transfer may also be carried out directly on different removal means during separation, e.g. alternating with different grippers.
  • FIG. 6 another embodiment of the invention is shown.
  • the printed products are offset slightly in the direction of the arrow S in front of the separation and removal in the direction of the main conveying direction P substantially at right angles to the guide surface 2.
  • This transverse offset can be effected by a simple lifting means, for example a sheet 28 which acts on the side edges of the printed products.
  • the separation by means of the reloading means 5 can be simplified.
  • the following printed products can be retained by means of a retaining means 29 falz document in a simple manner. After separation, the printed product are conveyed away in the manner described above by means of the removal means 9.
