Definitions

  • the invention relates to a method and a device for producing printed matter according to the preamble of patent claim 1 and patent claim 4.
  • Such a method and such a device are known, for example, from EP-A-0 562 443.
  • a method and a device for producing printed matter such as e.g. Advertising materials, described, in which a flexible material web is continuously unwound from a rotatably mounted roll and fed to individual stations of a processing line, on which e.g. Punchings, perforations and glue applications can be carried out.
  • sensor and control devices known per se and not further shown in this document, periodic markings are determined on the material web and the speeds of conveying means along the processing line are controlled accordingly.
  • the material web is pulled through the processing section under a tensile stress exerted on it by the conveying means.
  • the tensile stresses increase from station to station, so that the material web is exposed to an increasingly higher tensile load.
  • This can be disadvantageous for carrying out certain processing steps, for example when punching out window openings and then sticking a window film over the punched-out area. Due to the constantly increasing tensile stress, the material web in the punched-out area is warped irregularly, so that the window film that is stuck on during the subsequent relaxation can warp, resulting in an unusable end product.
  • the present invention is based on the object of creating a method and a device of the type mentioned at the outset, in which or in which the individual processing steps on the material web can be carried out under optimal conditions in order to produce high-quality end products.
  • the invention is based on the knowledge that the flexible material web should, if possible, be passed through the individual processing stations with a tensile stress corresponding to the respective processing step.
  • the tensile force exerted by the train arrangements on the material web is set as a function of the processing step to be carried out at the individual processing stations. In this way, the tensile force on the individual processing stations can be increased or decreased between certain limits in accordance with the needs and the changes in the material web caused by the processing, without changing the actual conveyance of the material web through the processing line.
  • the material web is preferably covered by a feed unit arranged at the beginning of the processing section conveyed essentially constant delivery speed into the processing line, whereby a corresponding short-term acceleration or deceleration of the material web in the feed unit ensures that the periodic markings on the material web run past a reference point in exact chronological agreement with the overall cycle in order to process the processing steps at the right place to be able to carry out the material web.
  • a feed unit arranged at the beginning of the processing section conveyed essentially constant delivery speed into the processing line, whereby a corresponding short-term acceleration or deceleration of the material web in the feed unit ensures that the periodic markings on the material web run past a reference point in exact chronological agreement with the overall cycle in order to process the processing steps at the right place to be able to carry out the material web.
  • FIG. 1 shows a first part of a device according to the invention for producing printed matter and a schematic representation of the various processing steps
  • FIG. 2 shows a second part of the device adjoining the first part, as in FIG. 1, 3 shows the drive unit for the various work stations and for the associated pairs of pull rollers, and below that shows the possible web tensions between two successive pairs of pull rollers,
  • FIG. 5 shows the arrangement of the scanning device on a processing station.
  • the device 1 shown in FIGS. 1 and 2 for producing printed matter, in particular form and advertising printed matter with a window film, is run through from right to left and is also described in this order.
  • a flexible material web 2 for example a printed paper web, with the processing steps carried out in the various workstations is shown below the device 1.
  • An unwinding station 3 with a rotatably mounted roll 4 from the flexible material web 2 is provided as a store for the flexible material or paper to be processed. This is followed by a so-called loop memory 5.
  • the material web 2 is then conveyed by a feed unit 6 into a processing line, generally indicated by the reference numeral 7, with an essentially constant delivery speed V.
  • the loop memory 5 serves to compensate for differences in the unwinding speed of the roll 4 and the delivery speed V of the flexible material web 2. If the loops that form become too long, a sensor (not shown here) responds in a manner known per se, which causes a delay in the unwinding speed.
  • the feed unit 6 has a pair of compensating rollers 8 and various feed rollers 9 forming a double loop with the material web 2, which are followed by a reading or scanning device 10 provided between two tensioning rollers, which reads periodic markings 11 on the flexible material web 2 scans.
  • the periodic markings 11 can be small lines or also certain images such as bar codes or the like, as are usually found on printed matter and printed matter.
  • a punching module 12 is provided directly adjacent to the feed unit 6 and has at the beginning a pair of pull rollers 13 with a reading or scanning device 14. Furthermore, a punching roll 15 equipped with punching knives and a counter-pressure roll 16 are provided, with which a window opening 17 is punched out of the paper web 2.
  • the flexible material web 2 is then conveyed further to an adhesive module 18, which at the beginning again has a reading or scanning device 19 and further consists of a plate cylinder 21, an impression cylinder 22 and a metering unit 23.
  • the plate cylinder 21 has frames 24 made of a rubber-elastic material distributed over its surface at regular intervals over its surface.
  • the adhesive in particular glue, is applied to the frame 24 by means of the metering unit 23 and correctly in the plate cylinder 21 Working cycle printed around the window openings 17 in the paper web 2.
  • the excess adhesive is collected by a container 26 via a channel 25 and then returned to the metering unit 23.
  • a pair of pull rollers is not provided in the adhesive module 18 for reasons mentioned later.
  • the paper web 2 is then conveyed further to an application module 28, which at the beginning in turn has a reading or scanning device 29 and also consists of an overlying blade cylinder 30, a middle suction cylinder 31 and an impression cylinder 32 below.
  • a transparent film 33 is guided over various deflection rollers 34 to the suction cylinder 31, which is provided with sieve holes (not shown here) and is connected to a vacuum unit. Due to the negative pressure, the film 33 adheres to the cylinder surface and is cut to the correct size by the blade cylinder 30. This cut window film 35 is then printed in the correct place on the window opening 17 of the paper web 2 surrounded by adhesive.
  • the application module 28 has a pair of pull rollers 36 which pulls the paper web 2 out of the cylinders 31 and 32 with a predetermined pull.
  • the paper web 2 is then conveyed to a perforating module 37, which initially has a pair of pull rollers 38 and further consists of a perforating cylinder 40 covered with perforating blades and a smooth, hardened impression cylinder 41.
  • a perforation 42 in the transverse direction.
  • Deflection rollers 43 are also provided at the output of the perforation module 37.
  • the paper web 2 is then transported further via dancer rollers 45 to a cross-cutting module 46 which, after the dancer rollers 45, has a reading or scanning device 47, a pair of pull rollers 48 and a blade cylinder 49 with a correspondingly designed counter-pressure cylinder 50.

  • All processing stations are driven by a single drive motor 56 via a common drive shaft 55, which is preferably designed as a cardan shaft.
  • a superposition gear 58 is driven, which is connected to the various cylinders 60 of the processing stations 61 via a further belt 59 in rotary drive connection.
  • the superposition gear 58 is itself drive-connected to a stepper motor (not shown) (see FIG. 5) and has a circumferential register of 360 °.
  • the position of the interacting cylinders 60 of a processing station 61 can thus be determined by the respective superposition gear 58 in accordance with the scanned periodic markings 11 on the paper web 2 can be set, as will be described in more detail with reference to FIG. 5.
  • the pair of pull rollers 63 (corresponds to the respective pair of pull rollers 13, 36, 38 or 48) of the individual processing stations is driven by the common drive shaft 55 via a belt 62.
  • the lower roller 64 of the pair of pull rollers 63 is connected to the belt 62 in a rotary drive connection via an adjustable coupling 65, in particular an electrically adjustable magnetic powder coupling.
  • the tensile force on each pair of pull rollers 63 can be set individually in a range from 0 to 250 N.
  • the web tension can thus be set at each selected processing station 61 depending on the requirements for the processed flexible web 2.
  • curves a, b and c of web tension S below the diagram of drive unit 54 are given as examples of a different setting.
  • Curve a represents a slightly increasing web tension between the pairs of pull rolls of successive processing stations 61.

  • the respective pair of pull rolls 13, 36, 38 or 48 has the task of requesting the material web 2 through the processing section 7.
  • the throughput speed of the material web 2 is not changed by the respective pair of draw rollers 13, 36, 38 or 48.
  • the measures explained in detail below with reference to FIGS. 4 and 5 are taken (individually or together).
  • FIG. 4 the drawing-in unit 6 with the drawing-in rollers 9 and the associated reading or scanning device 10 are shown purely schematically.
  • the feed rollers 9 are driven via the common drive shaft 55 and a superposition gear 67 arranged directly thereon and provided with a stepping motor 66.

From these time pulse signals Z Is . and ZGg Q ⁇ , a correction signal ZG j - orr is determined in the comparison unit 68 and applied to the stepping motor 66 in order to briefly accelerate or decelerate the material or paper web 2 in accordance with a determined deviation 6ZG between Z Is ⁇ and ZGg Q.
  • a correction needs to be carried out only once in the form of a pre-shift or set-back so that the respective processing steps can then be carried out with respect to the periodic markings 11 at the correct location.
  • a comparison unit 68 is provided, which in this case contains the current actual time pulse Z Ist with the target time pulse ZE coordinated with the work cycle of the processing station 61 should compare and a correction signal outputs the cylinder 60 of the respective work station 61 for the work cycle.
  • this correction signal ZE Korr is used to start up the stepping motor 66 of the superposition gear 58, as a result of which the deviation ⁇ ZE between Eg 0 n and z i st corresponds to a brief shift in the starting point of the work cycle, ie a rotation of the machining cylinder 60.
  • the delivery speed V of the paper web 2 in the area of the respective work station 61 thus remains unchanged and the rotational speed of the cylinders 60 is briefly increased or decreased in accordance with the determined deviation ⁇ ZE.
  • the delivery speed V can be set between 10 m / min and 200 m / min depending on the printed product 51 to be produced. In the production of form and advertising printed matter with viewing windows, the constant delivery speed and throughput speed lie between approximately 120 m / min and 150 m / min.
  • no pair of pull rollers is provided between the punch module 12 and the adhesive module 18 and between the adhesive module 18 and the application module 28.
  • the punched-out window opening 17 is thus not additionally subjected to tensile stress, so that the window opening 17 maintains its shape in this area. Only when the window film 35 has been applied to the application module 28 does the paper web 2 in the region of the window opening 17 again have sufficient inherent stability through the window film 35 to be subjected to an additional tensile stress by the pair of pull rollers 36.

Abstract

Pour la fabrication d'imprimés tels que les matériels de publicité et produits similaires, on réalise sur une feuille continue de matériau flexible (2) alimentée en continu des opérations de transformation comme, par exemple, l'estampage, la perforation, l'application de colle, la coupe en travers, dans différents postes (12, 18, 61) le long d'une ligne de transformation (7). La feuille continue (2) est introduite dans la ligne de transformation (7) à une vitesse prédéterminée sensiblement constante, par une unité d'entraînement (6), tirant dans le sens de déplacement et placée en amont de la ligne de transformation (7). Au moins une partie des postes de transformation (12, 61) sont pourvus de paires de rouleaux de traction (13, 63). La force de traction exercée par ces derniers sur la feuille continue (2) est réglable pour le poste de transformation associé (12, 61) - indépendamment des autres postes de transformation -, notamment en fonction de l'opération à exécuter dans le poste de transformation associé (12, 61).
