Definitions

  • the invention relates to a method and a device for inserting insertion objects between the sheets of multi-sheet products, in particular multi-sheet printed products according to the preamble of claims 1 and 15, respectively.
  • a multi-sheet product consists of a plurality of sheets, for example rectangular sheets of paper, which (in the closed state of the product) are stacked together and held together in the region of an edge.
  • Each of the sheets thus has an edge that is not separable from the corresponding edges of other sheets (fixed edge), and for example three edges that are separable from the corresponding edges of the other sheets (separable edges).
  • a multi-sheet product is opened, for example, by pushing an opening element between the sheets, such that a number of sheets is pivoted about an axis parallel to the fixed edges of the sheets with respect to a further number of sheets or with respect to the remaining sheets such that two or several stacks of sheets are created.
  • the fixed edges of multi-sheet printed products can be held together by, for example, one or more interlocking folds, binding, stapling or a tool that does not belong to the printed product and temporarily holds the edges together.
  • Newspapers, magazines, books, booklets, sheets folded into each other or temporarily held stacks of loose sheets are all multi-page printed products.
  • Insert elements are inserted between the sheets of multi-sheet printed products for various purposes.
  • opening elements are inserted to open the products so that inserts can be inserted.
  • sheet edges lying one on top of the other are usually first separated from one another at at least one point in the closed product, in such a way that at least between two adjacent sheets of the product there is a distance at least in the region of one of their separable edges, into which an opening element is then pushed.
  • the opening element By inserting the opening element, the sheets or a part thereof are pivoted about the fixed edge, that is, the printed product is opened and, if necessary, held in this open position.
  • the edge separation preceding the insertion of the opening element is carried out as far as possible from the fixed edge of the sheets.
  • an opening element with an insert slot is usually used, the insert slot being arranged essentially parallel to the fixed edge of the multi-sheet printed product and the insert being inserted through the insert slot.
  • a suction is exerted on the top side of multi-leaf printed products conveyed in a lying position at a point remote from the fixed edges, which is capable of lifting the top sheet for an insertion process.
  • multi-sheet printed products can only be opened between the top sheet and the rest of the sheets.
  • the sheets of a folded printed product are pressed together by a printing element, the separable sheet edges being pressed apart by the pre-tension in the sheets due to the folding, so that an insert element can be pushed between them.
  • the procedure can only be applied to folded products of a certain type and the insert object can only be inserted in the middle.
  • products with a pre-fold (sheets that are not exactly folded in the middle) or corresponding products with narrower and wider sheets are opened by compressing the wider sheets so that they bulge against the narrower sheets and thereby move them away , whereby the corresponding edges are separated and an opening element can be inserted.
  • This procedure can only be used for products with sheets of different widths (e.g. with pre-fold) and harmlessly deformable sheets.
  • the product is always opened between narrower and wider sheets, so a product with a pre-fold is always opened in the middle.
  • a printed product conveyed lying with the fixed edges of the sheets in the conveying direction towards the rear is opened by applying a braking force from above, which delays the upper sheets compared to the lower ones and thereby separates the corresponding edges between an opening element can then be pushed.
  • This method can also only be used for products with harmlessly deformable blades.
  • a folded product is opened in the middle using this procedure.
  • the corresponding sheets In order to ensure opening at a certain other point, the corresponding sheets must be pretreated on the sides lying one on top of the other in such a way that their mutual friction is reduced.
  • the methods and devices mentioned are all applicable to multi-leaf products with certain properties and are only suitable for an insertion process at a very specific point (for example in the middle).
  • the methods according to the two Swiss Patent Nos. 641113 and 644815 are available, both of which are based on the fact that with a sharp edge separating element is stuck between the superimposed sheet edges of the closed printed product.
  • the edge separating element inhibits the movement of a number of sheets, which thereby bulge at least at one point, as a result of which the remaining sheets are raised and thereby deflected at an opening element.
  • the common disadvantage of the two methods is that the separation of sheet edges lying on top of one another is accomplished by inserting a pointed object, which can easily lead to injuries to the sheets. Furthermore, the puncture accuracy is more or less limited depending on the quality of the flower of the product to be opened.
  • the object of the invention to provide a method and a device of the type mentioned at the outset, with which or with which simple, reliable and, above all, gentle multi-leaf products can be opened in order to insert the insertion objects between the separate sheets , largely independent of the type of connection between the fixed edges of the sheets (fold, stapling, binding, temporary holding together, etc.), largely independent of the mechanical properties of the sheets (deformability, rigidity, friction) and largely independent of the number of sheets which the product exhibits.
  • the method should also be applicable to continuously conveyed products.
  • the method and the device should also make it possible to insert objects at the same time into products having a corresponding number of sheets.
  • CH-A-408 970 describes a method and a device for separating folded sheets and placing them on a roof-shaped saddle, in which the sheets are removed from a stack by means of separating rollers, opened and then placed on the saddle become.
  • To spread the sheet halves one sheet half is held on the circumference of the separating roller, while the other, free sheet half flakes off the separating roller.
  • the outside of the sheet with respect to the separating roller can be blown with air. Furthermore, the use of blown air to keep the already open sheet open is proposed in this document.
  • the main feature of the method according to the invention for inserting objects between the sheets of multi-sheet products, in particular between the sheets of multi-sheet printed products, at at least one position which can be predetermined in any way, is that the at least partial separation of sheet edges in the first method step is not as according to the prior art a mechanical instrument in the form of a pointed separating element but a gas stream, in particular an air stream, is used.
  • the air flow is directed essentially parallel to the surfaces of the sheets against an end face of the closed, multi-sheet product, which is formed by separable sheet edges lying one on top of the other. Due to the dynamic pressure which occurs when the air flow strikes the end face, the sheet edges are separated from one another and are kept stable in this separate position by the air flowing into the spaces between the sheets as long as the air flow is effective.
  • an insertion object for example an opening element
  • an insertion object is then pushed between the edges separated by the air flow, as a result of which the printed product is opened and opened more or less, for example, in accordance with the requirements of further processing.
  • the method according to the invention is not limited to the insertion of opening elements, but can, as will be explained in the following, be used for other objects which are to be inserted into multi-leaf products.
  • the separable sheet edges are individually fanned out.
  • This fanning out is all the more regular, that is, the resulting distances between the separated sheet edges become more regular, the more similar the sheets are in their mechanical properties and in the quality of the edges to be separated, and the more uniform the air jet over the entire thickness of the fanned out product works.
  • the edges are fanned out the wider, the smaller the resistance of the sheets to the deformation (of deformable sheets) or displacement (of stiff sheets) necessary for the fanning out and the stronger the air flow.
  • the edges of all the sheets are fanned out, but only the edges of some sheets, in extreme cases only the edges of two adjacent sheets separated.
  • Another advantage of the method according to the invention is that the sheet edges do not have to be mechanically manipulated for the separation, so that it is also suitable for products of high quality made of sensitive material Application can come.
  • the figures now show the method according to the invention in an exemplary application.
  • This is the insertion of an opening element into multi-sheet printed products in order to open them for inserting inserts.
  • the printed products are usually conveyed in a channel with a V or U-shaped cross-section with the back or fold (fixed edges of the sheets) against the apex line of the channel and thereby opened and kept open for insertion.
  • the product can or must be held in the area of the back or fold.
  • FIG. 1 shows the principle of the method according to the invention in the first, exemplary application mentioned above in a three-dimensional representation.
  • the printed product D is conveyed in the conveying direction (arrow F), for example, by a slide 11 running along the channel 10.
  • a nozzle 20 is arranged against the end face of the printed product opposite the fold at an acute angle ⁇ to the conveying direction F and essentially parallel to the main planes of the sheets of the closed product D, through which an air flow LS flows against the printed product.
  • the air flow LS fans out the separable sheet edges of the printed product in the area of the front corner E in the conveying direction F, that is, it fans out the sheet edges on both sides of the corner E.
  • an opening element 30 is arranged in such a way that it is pushed between the fanned sheet edges at a predetermined point when the product is conveyed further.
  • the channel for the opening process is arranged in such a way (not symmetrically to a vertical plane) that the closed printed product D rests on one of its walls and thus assumes a defined position when the air flow strikes its end face.
  • the printed product can also be held in the groove in the area of the fold.
  • FIG. 2 shows a section perpendicular to the conveying direction F (section line II in FIG. 1) through part of the channel, where the sheet edges are not fanned out, that is to say, for example, in the region of the sheet corners at the rear in the conveying direction.
  • Figure 3 shows a corresponding section (section line III in Figure 1) through the channel 10 and the product D in an area with fanned leaf edges. These are distributed essentially at equal intervals over the space available between the side walls 10.1 and 10.2. Regardless of the strength of the acting air flow LS, the sheet edges can no longer be fanned out such that they take up the entire space between the side walls of the channel. For example, an opening element placed in the middle between the two walls will open each product in the middle.
  • FIGS. 4 and 5 now show insertion devices in which the method according to the invention for inserting an opening element for opening multi-leaf products, in particular printed products which are conveyed in a V-shaped or U-shaped channel, is used.
  • FIG. 4 schematically shows an insertion drum 40, as described, for example, in Swiss Patent No. 584153.
  • Multi-sheet printed products DD are introduced individually or in groups continuously into the cells of the rotating drum 40 and during a first rotation (conveying direction FF) in the cells that the Trough of Figures 1 to 3 correspond substantially, conveyed in the axial direction (conveying direction F) of the drum and opened at the same time, that is, in the area of a stationary opening element (not shown).
  • a row of nozzles or a single slot-shaped nozzle 41 is arranged over an area of the drum in such a way that the rotating with the drum 40 (conveying direction FF) as well as in Axial direction (conveying direction F) conveyed printed products are always hit by the most uniform air flow possible at the same point during the intended time interval.
  • the effect of the air flow on the end faces of the printed products must begin before they meet the opening element and in such a time that a stable fanning out of the sheet edges or sheet corners is possible before the opening element is pushed between the sheets. As soon as only a small part of the opening element (or the opening elements) is between the sheets, the effect of the air flow can stop.
  • FIG. 5 schematically shows an insertion section 50 for insertion, such as that used in Switzerland Patent Specification No. 669944.
  • the difference to the insertion drum is that the cells, which contain the multi-sheet printed products, do not rotate with a drum but are moved by corresponding conveying elements over an essentially straight conveying path (conveying direction FF). During this conveying, the printed products are likewise moved within the cells perpendicular to the conveying direction FF (conveying direction F) and opened at the same time.
  • the method according to the invention can also be used advantageously in such a system.
  • a row of nozzles or a corresponding, slit-shaped nozzle 51 is again arranged above the cells, in such a way that the air flow for fanning out the sheet edges or sheet corners and introducing the opening element (s) continuously onto the same end face location in both the conveying direction FF with the cells as well as transversely to it (conveying direction F) printed products conveyed in the cells.
  • the row of nozzles or the slit-shaped nozzle 51 must also be arranged at an angle to the conveying direction FF (see also FIG. 7 and corresponding description).

  • the air flow LS acts essentially parallel to the transport base 60 and at an angle ⁇ , which is smaller than 90 ° to the conveying direction F, on the end face of the printed products which is parallel to the conveying direction F and is formed by separable sheet edges.
  • the nozzle (not shown) can be used accordingly large product distance (as shown) to be stationary, or to be moved with each product during the necessary period in which the sheet edges or sheet corners are fanned out and kept open for inserting, for example, an opening element 61.
  • FIG. 7 shows in detail the view of the opening of the cells, the sequence of the opening method according to the invention, for example in the cells of a plug-in drum, as shown in FIG. 4 or in the cells of a plug-in section according to FIG. 5
  • the figure can also be understood as an illustration of the process in a single channel in which printed products are conveyed in linear succession, similar to that shown in FIG.
  • the multi-leaf product in cell a is in closed form on one of the cell walls.
