Definitions

  • the invention relates to a method for connecting layers of paper and a device for carrying out the method.
  • Adhesive binding, thread stitching and wire stitching have proven particularly effective for the mass binding of paper layers, such as occur in printers.
  • the perfect binding is preferably used for binding books, catalogs and specialist magazines.
  • gluing processes are often combined. For example, a low-viscosity layer of high wetting is applied first, followed by layers that improve adhesion. On in this way the bandage quality can be significantly increased compared to the simpler processes.
  • the width of the glue application is usually 4 mm. Approx. 15,000 copies / hour can be bound by gluing, whereby the glue drying on the assembly line must be allowed a considerable distance.
  • a major disadvantage of the process is the drying time that must be granted to the adhesive.
  • Thread stitching has a number of advantages and disadvantages compared to perfect binding. While the quality of the perfect binding largely depends on the type of paper, the thread binding is largely independent of the paper quality.
  • thread stitching can be seen as a relatively slow method and well suited for high-quality binding of books.
  • Wire stitching is of the greatest importance for stapling printed material in the form of booklets and brochures.
  • Rotary wire stitchers have a high performance but are relatively expensive. A copy of a booklet can be up to 100 pages long.
  • the wire clamp is pressed against an abutment without a locking mechanism by the spreading paper.
  • Single wire stitchers perform less than rotary wire stitchers per unit of time; but they are also expensive. However, the product can contain up to 300 pages.
  • Single wire stitchers have a stitch abutment with a locking mechanism.
  • wire stitching is the ability to fully open the booklet. There is no closed fold edge that covers part of the print information.
  • wire stitching is the fact that the material is applied through the clip in the back, which limits the stackability of the products. Furthermore, the selection, storage and processing of the suitable wire material requires additional effort. There are also limits to the reliability of wire stitching - especially when it comes to thick, more than 200-page layers of paper.
  • Ultrasonic welding is a known method for joining metals and plastics. The method is based on the fact that the weld metal is heated under the influence of ultrasound due to its internal friction in the contact region in such a way that the material to be joined is melted and thus welded. It is in this connection to the writing "Ultrasound for plastic joining" by R. Altena, W.-R.Behnke, L.Horvath, H.-J.Rheinhardt and W.Ruhland, published by Branson Schallkraft GmbH, Industriestrasse 48, D-6056 Heusenstamm.
  • This coating can be, for example, a printing ink that is applied during printing or a thin, quick-drying plastic film. If necessary, a suitable binder can already be incorporated during paper production. The simultaneous action of heat, pressure and a vibration movement result in sufficient adhesion of the paper layers even when a very small amount of binding material is present.
  • connection of layers of paper by gluing is known, but this method requires that glue must be applied to the adhesive immediately before the gluing. On the one hand, this requires an additional work step in which the paper sheets are individually provided with adhesive and, on the other hand, it must be ensured that the paper sheets prepared for connection do not touch prematurely.
  • the proposed ultrasound process allows the paper to be pretreated simultaneously with the printing for the subsequent connection can - the pre-treatment process can thus be integrated into the printing process - and above all that the further processing of the printed matter, such as cutting, arranging the individual sheets and folding the paper layers, is not impaired by the connection pre-treatment. It is particularly advantageous that the paper layers can be connected in analogy to wire or thread stitching.
  • FIG. 1 shows an example of the basic structure of an ultrasound device, such as is used for welding plastics:
  • the control unit 10 consists of a power supply unit 11, the amplifier 12, the high-frequency transformer 13 and a tunable positive coupler 14. The latter is connected to the input of the amplifier 12 and the high-frequency transformer 13 via the positive feedback circuit 15.
  • the ultrasonic oscillator 20 is connected to the high-frequency transformer as a frequency-determining element. This circuit ensures that the ultrasonic vibrator 20 can be operated in acoustic resonance, which is necessary for a good transmission of the vibration power from the source to the operating point.
  • the phase position of the high-frequency oscillator can be optimized by tuning the co-coupler 14.
  • the basic structure of the ultrasonic vibrator 20 is shown in FIG. 2.
  • This device is generally composed of an ultrasonic transducer 21 and the vibrating tool, the so-called sonotrode 24.
  • the ultrasound transducer 21 consists of a stack of piezo-ceramic plates 22 connected in parallel. If necessary, a sound amplitude transformer, a so-called booster 23, is interposed between the ultrasound transducer and the sonotrode. This passive element 23 causes an increase or decrease in the vibration amplitude.
  • the sonotrode the real thing che connecting tool, ensures at its tip 25 the transmission of ultrasonic power to the weld metal 26 to be connected.
  • An abutment 27 serves to absorb the contact pressure which the sonotrode end exerts on the weld metal 26.
  • the abutment 27 must be designed in such a way that it absorbs as little as possible of the ultrasonic power used, ie it must have the highest possible mechanical inertia with respect to the weld metal 26 and be as undeform
  • the system of ultrasonic transducer 21 - booster 23 - sonotrode 24 is operated in acoustic resonance. Longitudinal vibration is excited in most applications. Ultrasonic welding machines generally work at a frequency of 20 kHz to 40 kHz. Typically, the longitudinal oscillation amplitude at the tip 25 of the sonotrode 24 is approximately 100 ⁇ m at 20 kHz operation and approximately 50 ⁇ m at 40 kHz.
  • the device consisting of the control device 10 and the ultrasonic oscillator 20, is usually operated by means of a control system in such a way that the mechanical amplitude at the sonotrode end 25 has a constant, predetermined value, regardless of the damping by the weld metal 26.
  • the contact pressure which the sonotrode end 25 exerts on the weld metal 26 and the time of the ultrasonic action can be specified.
  • the choice of the booster 23 and the shape of the sonotrode 24 depend on the type of the weld metal 26 and the welding to be carried out. Examples of the most common forms of sonotrodes are given in the previously mentioned work “Ultrasound for plastics Fügen "by R. Altena, W.-R.Behnke, L.Horvath, H.-J.Rheinhardt and W.Ruhland.
  • 3 to 5 show some examples of sonotrodes which are particularly favorable for applications which will be mentioned later.
  • 3 shows a conical, 31, in a tip 32 tapered sonotrode 24, which is suitable for creating spot welds.
  • FIG. 4 illustrates a sonotrode with a flat sonotrode end 41 and a cutting-shaped welding edge 42.
  • This embodiment of the sonotrode 24 is particularly suitable for producing a long, narrow weld seam.
  • FIG. 5 shows a combination of the two embodiments of FIGS. 3 and 4.
  • the flat sonotrode end 41 is designed in a similar cutting shape to that, 42, of FIG. 4.
  • the knife-shaped welding edge 42 provided with notches 53. Welding points lying in a long and narrow weld seam can thus be generated simultaneously.
  • Ultrasonic movement is carried out. Such matting could be weakly demonstrated with a longitudinal movement.
  • the paper layers are slightly moistened.
  • the paper structure is easily destroyed - a paper pulp is formed locally, as is present in the paper production.
  • the paper fibers are felted and glued in analogy to the actual paper production process. In this way, limited liability of the paper layers is already possible.
  • a laterally delimited strip 63 is defined in the fold region 62 of the booklet of the paper sheet 61 and is provided with a printing dye or a plastic which melts at a higher temperature.
  • Such strips 63 can, for example, additionally or alternatively be applied in regions 64 of sheet 61, where later insert sheets, registration and receipt forms, or art prints are inserted.
  • the stripe regions 63, 64 can either be applied as part of the printing process - for example by multiple coating using printing inks, a special printing dye containing a large amount of binder - or in an additional processing step on the paper 61.
  • pretreatment for the subsequent ultrasonic welding of the paper 61 consists in the application of a colorless binder, for example a very thin plastic film, which is not sharply delimited. Such pretreatment does not require any change in the printing process, for example by using a special printing dye.
  • the pretreatment could be accomplished, for example, by spraying the printed sheet in the binding region.
  • the material application which usually falls in the fold region anyway, would hardly be disruptive due to the minimal material application.
  • a further paper treatment consists in that the paper sheet is pretreated on all sides either during the production process during or after the printing process for the ultrasonic welding. With a pretreatment during or immediately after papermaking, respectively. Before or during the printing process, for example, a desired gloss effect, moisture protection or the like could also be added can be achieved.
  • binder or water can be injected, for example, into the fold region 63 of the paper layers already stacked.
  • the paper layers can be pre-perforated and, at the same time or subsequently, provided with binders or water by means of hollow needles or cannulated needles.
  • binders or water by means of hollow needles or cannulated needles.
  • an abutment 27 is necessary to absorb the contact pressure which the sonotrode 24 exerts on the weld metal 26.
  • this abutment can be a plate, as is shown in Fig. 7.
  • the abutment is an instep-shaped device 27 ', on which the paper layers in the scale flow of the printing press, as shown in Fig. 8, are stored.
  • the abutment can be rod-shaped or instep-shaped.
  • FIG. 9 shows an example of a basic illustration of a printing system with an integrated ultrasonic welding device for paper layers.
  • the paper passes from the paper loading device 90 to the printing device 91, which can consist of several printing stages.
  • the printed material is then cut lengthwise and, if necessary, fed to a cutting device 92.
  • the printed matter then reaches, for example, the welding pretreatment device 94, where binder is printed or sprayed on.
  • the substrate is on finally bundled and carried on. If necessary, welding pretreatment can be carried out on the bundled layers of paper by binder binding.
  • the printed matter then arrives in the ultrasonic welding device 95, where the paper layers are connected.
  • the bound products are then accepted by the removal device 96, for example as a shingled stream 93.
