Definitions

  • the invention relates to a method and a device for processing a material web, in particular for producing individual sections from a path of a limp material moving along a material movement direction, for example made of paper.
  • a material movement direction for example made of paper.
  • Newspaper printing uses paper webs wound on paper rolls. These rolls of paper are unrolled or unwound and the web is passed through a printing machine with the aid of a plurality of rollers. In the printing press, ink is usually applied to the paper web in the offset printing process. By means of a so-called Klappenfalzapparats the paper web is cut and thus created individual, the newspaper pages forming sections.
  • the front end of the paper web is gripped by means of dot needling of a folding blade cylinder of the flap folding apparatus, and the paper is at least partially transported along its circumference by a rotational movement of the folding blade cylinder.
  • a cutting blade cylinder arranged parallel to the folding blade cylinder is in contact with the paper and rotates in the direction opposite to the rotational movement of the folding blade cylinder.
  • cutting blades extending along the axis of rotation are mounted thereon. If these knives hit the paper web, they are severed there. Suitably located on the folding blade on the corresponding to the cutting blades of the cutting blade cylinder so-called cutting strips. These cutting bars are used both to ensure the most accurate cut and a protection of the cutting blade and / or the folding blade itself. Comparatively close behind each of the cutting bars are theillonumadeln mentioned above. In this way, the paper web and the created sections are relatively certainly pulled without kinking them by the Klappenfalzapparat.
  • a disadvantage of the Klappenfalzapparat is that the size of the created sections is always the same and given by the distribution of the cutting blade and the cutting strips on the respective cylinders. If sections of a different size are to be made, these two cylinders must be replaced.
  • a device for producing individual, format-appropriate material sections from a web.
  • An essential feature here are so-called cross tables with NOTEumadeln, by means of which material web and the sections are transported along a direction of movement.
  • As a cross table an association of two linear motors is called servo drives, wherein the respective direction of movement is orthogonal to each other.
  • servo drives By means of one of the cross tables, a portion of the web is pulled along a direction of material movement and separated by a cutting blade which cooperates with a cutting bar. This is attached to another of the cross tables.
  • the length of the created sections can be varied as desired, since the two-dimensional movability of the two linear motors of each of the cross tables makes it possible to move them along a plurality of trajectories while avoiding collisions between the linear motors.
  • the sections are transported to a folding blade via a pair of rollers downstream of the cross tables. This brings at a predetermined location a fold in the sections, with a gripper engages the sections. After opening the gripper, the folded sections fall on a sheet delivery, which transports them away.
  • the invention has for its object to provide a method and an improved apparatus for processing a material moving in the direction of moving material web of a pliable material. Under Edit is here in particular the production of individual sections of the material web understood.
  • the object concerning the method is solved by the features of claim 1 and the object relating to the device by the features of claim 5.
  • Advantageous developments and refinements are the subject of the respective subclaims.
  • the method is used in the context of processing the production of individual sections of a material web which is moved along a material movement direction and consists of a pliable material.
  • the material is in particular paper, whereby rope, fabric, foil or the like would be conceivable.
  • the method is used in particular in the production of newspapers or other printed products.
  • Double slide linear motor is understood to mean an electric drive machine as a servo drive with a stator extending along a direction of movement, the direction of movement being linear. At least two runners assigned to the drive machine interact with the stator and perform a translation along the direction of movement during operation of the double slide linear motor.
  • a double carriage linear motor is a conventional linear motor but has two rotors. The runners are independently movable, both their position relative to one another and their respective position relative to the stator is variable. However, the order in which the runners are relative to the stator along the direction of travel is constant.
  • Each double carriage linear motor has a first carriage in the material movement direction and a second carriage, each comprising a driver.
  • a first step by means of the driver of the first carriage of the first double slide linear motor, a region corresponding to the length of the section the web pulled along the material movement direction.
  • the driver of the first carriage engages the web at the front material or portion of the section in the material movement direction.
  • the area is transferred to the driver of the second carriage of the second double slide linear motor.
  • the driver of the second carriage engages the web at the front region or part of the section.
  • these two carriages are moved during the transfer in the material movement direction at the speed with which the web is moved.
  • the two drivers are in contact with the web, so that no uncontrolled movements of the web arise.
  • the web is gripped by means of the driver of the first carriage of the second double carriage linear motor.
  • the gripping takes place in the direction of movement at the foremost area of the section.
  • the area is separated from the web by a cutting tool, wherein the separation of the web with the first carriage of the first and second Doppelschlittenlinearmotors takes place.
  • the thus produced portion of the pliable material is transported away with the second carriage of the second or first Doppelschlittenlinearmotors.
  • the length of the wider area and thus the length of the newly created section may differ from the length of the original area.
  • the method it is possible to produce portions of the web directly one behind the other, the length of which varies with each other.
  • the created sections are further processed, for example folded and / or sorted.
  • the cutting tool is carried by the first carriage of the second double slide linear motor and another cutting tool by the first carriage of the first double slide linear motor.
  • this cutting tool By means of this cutting tool, the material is cut in the direction of movement in front of the driver of the first carriage and the area located in front of the driver is separated from the web. Since the cutting tool is carried by the carriage, which moves with the speed of the web, thus, a movement of the web at different speeds is allowed, in each case a straight, ie running at a right angle to the material movement direction cutting edge can be created.
  • the apparatus in the course of processing, at least for separating individual sections from a path of a limp material moving along a material movement direction, is suitably used for the production of newspapers within a printing shop.
  • a stator of a first and a second double slide linear motor are arranged.
  • On each of the two stators are movably mounted a first and a second carriage, each of the carriages comprising a rotor.
  • the rotor cooperates with the stator such that the carriage can be moved along the stator.
  • the stator has a number of permanent magnets and the rotor has a coil which interacts with the magnets of the stator when the current is applied in a suitable manner.
  • the rotor is designed as a permanent magnet and the stator comprises a number of coils, or both the rotor has an electromagnet and the stator has a number of electromagnets.
  • Each carriage has a driver, by means of which the material is transported along the material movement direction.
  • the sections are removed from the web by means of the drivers of the second carriages and conveyed to another machine, which processes the sections, for example folds.
  • the sections can be transferred, for example, to another driver, or more preferably, the sections are at least partially processed while they are in contact with those drivers.
  • each of the carriages has a pivoting motor, which is operatively connected to the respective carrier of the carriage.
  • the swivel motor is designed in particular as a 90 ° swivel drive. By means of the swivel motor, it is possible to pivot the driver on the web.
  • the drivers on each other parallel and arranged on both sides of the web gripper bars.
  • the gripper bars are pivoted by means of the pivot motor from a position parallel to the material movement direction in a position perpendicular to this position and in addition, for example, with the same drive or by means of another drive, against each other. In this way, the material web between the gripper bars of each driver is held securely and can thus be gripped and pulled. With a reverse to this movement, the drivers are released from the web.
  • the rotor is designed as an electromagnet and thus has a coil.
  • the rotor is ironless and thus has the lowest possible mass. In this way, it is possible that the carriage can be accelerated and decelerated comparatively quickly, so that the processing of comparatively many sections in succession in can be done in a short time. Further, the speed with which the web is moved can be increased compared to a device in which a rotor is used with an iron core and therefore with a large inertia.
  • the two Doppelschlittenlinearmotoren are advantageously arranged on opposite sides of the web and in particular diametrically to the web.
  • the device has a control unit.
  • the control unit is configured programmatically and / or circuitally to control the individual carriages of the two double slide linear motors.
  • the control unit comprises, for example, a microprocessor.
  • the carriage and its driver are synchronized with the control unit to each other such that the above method is performed by means of the device. Further, the carriages are tuned to each other so that they do not collide during operation.
  • Fig. 1a to 1c is shown schematically in a time course, a device 2, a first double slide linear motor 4 with a stator 6 and a second double carriage linear motor 8 with a stator 10, wherein the two stators 6, 10 are arranged parallel to each other and to a straight material movement direction 12.
  • the first double-slide linear motor 4 and the second double-slide linear motor 8 have, in the material movement direction 12, a first slide 14 and 16 and a second slide 18 and 20, respectively, which are movable relative to the associated stator 6 and 10, respectively.
  • Each of the carriages 14, 16, 18, 20 has a driver 22.
  • the slides 14, 16, 18, 20 are controlled by means of a control unit 24, which is connected via supply / data lines 26 with the two double slide linear motors 4, 8.
