Definitions

  • the present invention relates to a method and an apparatus for trimming printed products according to the preambles of the independent claims.
  • Multi-layer, in particular single or multiple folded printed products e.g. Magazines generally have to be trimmed on at least one, but usually on two or three pages.
  • the cutting process into the dynamic production process, i.e. to cut at full rotational output (e.g. 80,000 copies per hour).
  • CH-PS 650 967 and EP-PS 0 017 878 each show a device for the lateral trimming of paper sheets, in which the paper sheets produced in the form of a shingled stream on a flat conveyor belt against one or more rotating ones Cutting knife transported and trimmed from the side.
  • acceptable cutting results are usually achieved in this manner, these devices have some disadvantages. So it turns out to be difficult and expensive to precisely align the individual printed products in the shingled stream.
  • the stream of shingles creates a cavity between the individual products and the base, which leads to tearing of the cutting edges, in particular the first sheets, and irregular cutting marks, especially in the case of thick material to be cut. If the products are not only to be cut on the sides parallel to the conveying direction, the stream of shingles must be deflected by 90 ° or the printed products must be rotated individually, which is contrary to an optimal spatial arrangement of the production line and is technically complex.
  • the CH patent application 4876 / 85-4 shows a device for trilateral trimming of printed products with an endless path around two drive wheels with a number of compartments, which are each intended for receiving a printed product.
  • three cutting devices are arranged with a plurality of cutting and counter knives rotating in pairs parallel to the path, past which the printed products are guided and trimmed accordingly.
  • a good cut is achieved in this way even with thick printed products.
  • it proves to be disadvantageous that the precision that is essential for the exact cut straight guidance of the circulating path is technically rather complex and that the cutting devices are relatively maintenance-intensive.
  • Another device according to CH-PS 583 611, with which the printed products are cut individually, comprises a rotating cell wheel, the individual cells of which are each intended to receive a printed product and are provided with movable knives which can be actuated via common control cams and counter-knives which interact with them.
  • This device is relatively complicated in construction and accordingly expensive to maintain.
  • the present invention seeks to remedy this. It sets itself the task of creating a reliable and precise method and a simple, maintenance-friendly and inexpensive device with which a high-quality trimming of multilayer printed products is made possible in a continuous process, in particular a high-performance manufacturing process. This task be solved by the characterizing features of the independent claims.
  • the main advantages of the invention can be seen in the fact that on the one hand the throughput required for a dynamic high-performance process is realized and at the same time a cutting quality comparable to static cutting methods is achieved by the knife parts (preferably counter knife) which are fixed relative to the material to be cut.
  • a suitable choice and arrangement of the second knife parts (preferably cutting knife) makes it possible, depending on the nature, size and thickness of the printed products to be trimmed, to determine the cutting curve similarly to the static cutting devices mentioned above in such a way that an optimal distribution of the Cutting forces result. This will make the qualitative advantages of a static and the performance advantages of a dynamic cutting process.
  • the printed products can be trimmed on three sides in a single pass without the product flow having to be deflected.
  • Figures 1a and 1b show the principle of the method according to the invention.
  • the spatial sequence is viewed from the side
  • Figure 1b shows the same sequence from above for better understanding.
  • Phase I represents the printed products 2, which are conveyed, for example, in the form of a shingled stream 1, ie partially overlapping one another, as are usually conveyed away by a rotary press.
  • the shingled stream is dissolved, with each individual or, as in the illustration, several printed products jointly being assigned a first knife part 3 which moves with the printed products (phase II).
  • the printed products conveyed in the stream 1 can each comprise several elements.
  • the printed products denoted by 2 in the figure can thus consist of several individual products, for example magazines lying one above the other or parts of a newspaper inserted into one another. If the term "printed product” is used, one or more (eventu only temporarily) to understand individual products combined into one unit.
  • the printed products and the associated first knife part 3 are aligned along an intended cutting edge 4 and brought into contact (phase III) and guided past a second knife part 5.
  • the first 3 and the second knife part 5 are brought into cutting engagement, so that the printed products 2 are trimmed along the intended cutting edge 4 (phase IV).
  • the second knife part 5 is shown in FIG. 1 as a stationary, rotating cutting knife.
  • the second knife part can e.g. be designed as a stationary, non-rotating blade or also as a movable, non-stationary knife part.
  • the moving knife part 3 is preferably designed as a counter knife and the knife part 5 as an actual cutting knife, their functions are of course also interchangeable.
  • the method described here whether the printed products are fed in as a shingled stream or in some other arrangement. It may well be that the printed products are already delivered individually or in groups from a previous work process.
  • the printed products are advantageously guided past the knife part 5 in such a way that the side edge after cutting is essentially perpendicular to the surface of the printed product.
  • a preferred embodiment of a device according to the invention for triple-sided trimming of multilayer printed products will now be described with reference to FIG. To emphasize the essential points, the figure is limited to a largely schematic representation.
  • a drum rotor 11, which rotates about a fixed axis 13, is provided on its periphery with a plurality of cells 12, which are preferably arranged radially and are opened laterally and towards the outside.
  • the multilayer printed products 2, which are fed in the form of a shingled stream in the direction of arrow A, are each inserted into one of these cells by a feed device (not shown). Due to the rotation of the drum rotor 11, the printed products located in the cells 12 are first guided past a first stationary cutting device 14, with which e.g.
  • the side edge facing away from the observer is trimmed.
  • the side edge of the printed products facing the observer is then trimmed by means of a second cutting device 15.
  • the cutting devices 14 and 15 are designed as disk-shaped rotating cutting knives.
  • a third cutting device 16 e.g. a cutting roller, the upper edge of the printed products is trimmed, whereupon the printed products, which are now trimmed on three sides, are removed from the cells 12 by a conveyor device (not shown) and conveyed further in the direction of arrow B.
  • the cells 12 of the drum rotor 11 are separated from one another by preferably radially extending cell walls 31.
  • the cell walls are either provided with three counter-knives which interact with the cutting devices 14, 15 and 16 or are designed directly as counter-knives. A detailed embodiment is described below with reference to FIGS. 8 to 12:
  • the advantage of the specific embodiment described here basically consists in the fact that with the drum rotor, a defined and precise guidance of the counter-knives interacting with the stationary cutting knives and thus a constant cutting quality can be achieved in a simple manner can be realized.
  • Figure 3 shows the device of Figure 2 in a development, the conveying direction is indicated by an arrow.
  • the inserted into the cells 12 and these laterally projecting, untrimmed printed products 2 are positioned, for example, by means of a lateral link 17 in the cells 12 to a defined position of the printed products - in particular the intended cutting edges 4, 4 '- in relation to the cell wall 31, which here also acts as a counter knife, and to create the cutting knife 14.
  • further scenes on the other side of the printed products or in front of the second cutting knife 15
  • the printed products can also be clamped in their cells direction are fixed in such a way that they are no longer moved until they have passed the second cutting knife 15.
  • FIG. 4 A device similar to that previously discussed is shown in Figure 4.
  • the function of the cutting knives 14 and 15 is perceived by rotating cutting rollers 18 and 19 arranged on the side of the drum rotor 11.
  • the axes of rotation of these cutting rollers are preferably arranged perpendicular to the axis of rotation 13, but in such a way that they do not cut them, so that - considering a single printed product - this does not cover an entire side edge at the same time, but rather continuously and in an analogous manner to those mentioned above
  • Cutting knives 14 and 15 is cut from one end of the side edge to the other. In the selected representation, the side edges of the printed products are therefore cut from the inside towards the outside.
  • the cutting devices 14, 15 and 18, 19 provided at different locations in the illustration can also be arranged opposite one another, that is to say the front and rear edge cuts are carried out simultaneously.
  • the arrows A and B and the indication of the direction of rotation of the drum rotor 11 are not mandatory. The device can thus also be operated in the opposite sense.
  • the invention makes it possible, in particular, to arrange the lateral cutting devices 14, 15 and 18, 19 in such a way that they are optimally used by, as shown in FIG. 2, a single cutting knife simultaneously engaging with three or four printed products.
  • the edge of a printed product is also continuously cut from one end to the other (here from the inside to the outside), which results in a high cut quality increases.
  • the surface of the cutting roller 16 is provided, for example, with spiral cutting edges, so that the printed products are cut at a similarly favorable cutting angle as the circular cutting knives, which corresponds to the slope of the spiral.
  • FIGS. 5a and 5b schematically show how the cutting forces acting on the printed products can be influenced and utilized by suitably arranging the cutting knife in relation to the drum rotor 11 and by selecting the direction of rotation.
  • the axis of rotation of the cutting knife 14 is relatively close, at a distance a, at the axis of rotation 13 of the drum rotor 11.
  • the printed products are cut continuously in this way from the inside to the outside (based on the drum rotor).
  • the cutting knife is displaced outwards by a distance b. In this case, the printed products are continuously cut from the outside towards the inside.
  • the direction and amount of the cutting forces acting on the printed products F 1 (tangential) and F 2 (radial) can be varied depending on the application.
  • the printed products are automatically fixed in the cell 12 by a suitable choice of these cutting forces.
  • FIG. 1 A single printed product 2, which is located on the periphery of the drum rotor 11, which rotates at a constant angular velocity ⁇ , moves at its outer end E n at a greater speed than at its inner end E 1 facing the axis of rotation 13.

  • the cutting angle ⁇ n 'at S n ' is significantly flatter than the cutting angle ⁇ 1 'at S1'.
  • the speed of the printed product at S n is greater than at S1 (v n > v1).
  • the cutting geometry is also influenced by the design of the cutting edges of the cutting knives.
  • the change in the cutting angle between S 1 and S n can be influenced by enlarging / reducing the cutting knife ( ⁇ i as a function of r i ).
  • the arrangement of the cut surfaces of the cutting devices with respect to the printed products located on the circular path is of importance in all of the embodiments.
  • the cutting surface of the cutting devices in the case of the cutting knives 14 and 15 corresponds exactly to the plane of the cutting knife.
  • the cut surface corresponds to the tangential surface to that surface line of the respective cutting roller which is closest to the printed products.
  • other possible cutting devices e.g. rotating wires
  • cylindrical cutting rollers instead of cylindrical cutting rollers, other geometric shapes can also be used. So it is conceivable the lateral cutting rollers 18 or 19 e.g. not cylindrical, but frustoconical.
  • the cylindrical roller 16 the axis of rotation of which is arranged parallel to the axis of rotation 13 of the drum rotor 11 to achieve a head cut perpendicular to the side edges, has the effect that the head edge of a printed product is trimmed along its entire length substantially simultaneously. If the head edge is also to be cut continuously from one end to the other, instead of the cylindrical cutting roller shown, another rotationally symmetrical body can be selected, the axis of rotation of which is slightly oblique to the axis of rotation 13. Assuming that the head edge of the printed products should run parallel to the axis of rotation 13 of the drum rotor 11, those points at which the cutting device cuts the printed product must be equally spaced from the axis of rotation 13.
  • the geometrical The location of all these intersection points of a single edge corresponds to a section from a helix, which can be approximated by a flat elliptical section if the axis of rotation is slightly inclined.
  • the ellipse section then corresponds to a surface line of the rotating body of the cutting device.
  • FIG. 1 An expanded embodiment of a device according to the invention is shown in FIG.
  • the device initially consists of a first drum rotor 11 and two laterally arranged rotating cutting blades 14 and 15, as has already been described in connection with FIG. 2.

  • the axis of rotation 23 of the drum rotor 21 is preferably perpendicular to the axis of rotation 13 of the first drum rotor 11.
  • the third edge - normally the edge parallel to the fold or collar - of the printed products can now be trimmed by a further cutting knife 24, so that With this device, the multilayer printed products can be trimmed on three sides in a single pass, whereby the advantages of a cutting knife compared to a cutting roller come into play.
  • FIG. 1 A preferred embodiment and mode of operation of the individual cells of the drum rotor will now be explained with reference to FIG.
  • the representation is chosen so that four different situations a) to d) are each shown from two different viewing directions: the right drawing shows a cell 12, in which the viewing direction runs parallel to the axis of rotation 13 of the drum rotor 11, while the left drawing shows the same cell from the direction of arrow D.
