Definitions
- the invention relates to devices for pulling a web of material into a machine according to the preamble of claims 1, 5 or 6.
- Devices of this type are used in printing presses in order to convey the beginning of the web of material along the desired drawing-in path through the printing press. This is necessary, for example, when moving in for a new production, or whenever a material web is torn off during the printing process, so that the beginning of the web of the new material web cannot be pulled through by means of a flying roll change.
- the printing units can be traversed along different conveying paths in order to be able to achieve correspondingly different printing results, so that when converting, the new material web must be drawn in along the corresponding feeding path.
- a device for pulling material webs in rotary printing presses in which the pulling-in means designed in the manner of a spring steel strip can be pushed through the outlet of the printing press along different pulling-in paths, between which it can be switched by means of switches.
- the pull-in means is driven by a fixedly arranged drive wheel, which comes into positive engagement with the pull-in means and the pull-in means through the printing press along its entire length.
- EP 0418 903 A2 discloses a device for pulling in a material web, wherein a pulling-in means is driven by a motor which is regulated as a function of measurement data determined during the pulling-in process. The regulation takes place with regard to a constant retraction speed or speed.
- DE 9409390 U1 discloses a device for pulling in a material web, a pulling means being driven by a stepper motor. A transport route already covered by the pull-in means is detected by means of sensors.
- the invention has for its object to provide devices for pulling a web of material.
- An advantage of the invention is, in particular, that the flexible and finely designed pull-in means can be wound up on a spool, so that only a small amount of space is required to store the part of the pull-in means that is not inserted into the printing press.
- the design as a finite drawing-in means, which is fastened at one end to a bobbin and can be completely wound up, is of great advantage that, in contrast to endless or rewinding drawing-in means, different drawing-in paths can be realized via switches.
- the drive of the pull-in means can basically be guaranteed in any way.
- the pulling-in means is carried out by driving the bobbin, which is used for winding or unwinding the Einzugmitteis can be driven in two directions. A separate drive wheel for driving the pull-in center can thus be dispensed with.
- a controllable electric motor is preferably used to drive the coil former, so that the coil former can be driven in a controlled manner with different rotational speeds and / or torques.
- the feed rate of the Einzugmitteis or the applied moment can then be adjusted by controlling the electric motor, a constant conveying speed or a comparable torque on the feed means.
- the electric motor can also be controlled in accordance with a speed (e.g. frequency) or a torque (power).
- the linearly directed feed speed of the pull-in center can be determined in a simple manner and can then be regulated to a desired value by corresponding regulation of the speed of rotation of the bobbin.
- a corresponding dependency of the target speed on the number of revolutions that is stored in the software as a control curve is also conceivable.
- the feed means can therefore preferably be in the form of a steel strip, in particular a spring steel strip, since steel strips have a high degree of flexibility and at the same time can transmit high tensile or compressive stresses.
- steel strips have a high degree of flexibility and at the same time can transmit high tensile or compressive stresses.
- plastic straps, chains or appropriately designed ropes is also possible.
- the pull-in means can be covered at least in regions with a friction-reducing layer.
- a friction-reducing layer it is possible to encase a steel strip pull-in means with a plastic layer, in order to thereby combine the material properties of the steel strip with high tensile or compressive strength with the desired low-friction material properties of the plastic.
- FIG. 1 shows a printing press with a device for drawing in a material web in a schematically illustrated cross section.
- a printing machine 01 for the treatment of material webs, for. B. of paper webs, a device 08; 09; 11 provided for retraction.
- the printing press 01 shown in cross section in the drawing has two printing units 02; 03 with two double printing units or four printing units and three reelstands 04; 06; 07 on.
- the devices 08; 09; 11 each consist of a pull-in center 12 designed in the manner of a spring steel strip 12, which is mounted on a rotationally symmetrical bobbin 13 can be wound up.
- the bobbin 13 is by means of a motor 17, for. B. an electric motor 17 (shown only for the upper bobbin 13), in particular by means of a controllable AC motor 17 with frequency converter.
- the control takes place in such a way that the speed is changed with a changing coil radius in such a way that the retraction speed is almost constant over time.
- the regulation can also take place in such a way that the electric motor 17 is operated at any time with a specific, predeterminable torque and thus leads to a largely constant web tension.
- This moment can e.g. B. constant for short retraction paths, and for longer retraction paths, for example, along a predetermined curve.
- the electric motor 17 can generally be controllable as a function of measurement data which are obtained during the pulling-in and which provide information about the progress and / or applied moments.
- the pull-in means 12 can be driven by means of a synchronous drive 14 formed by two rollers including the pull-in means.
- the synchronous drive 14 can also have a driven roller and a non-driven roller that can be set against it.
- the coil former also has a motor which, however, does not have to be controllable in the same way as the aforementioned electric motor 17.
- the electric motor 17 (dashed) is arranged to drive the synchronous drive 14 (dashed) and, as above, is regulated to a constant retraction speed or a constant or predeterminable torque.
- the coil former 13 has a central axis on which one end of the pull-in center 12 is fixed.
- lateral cheeks are provided at the ends of the central axis, on which the part of the pull-in center 12 wound onto the bobbin 13 is laterally supported.
- the finite drawing-in means 12 can be unwound from the bobbins 13 and, depending on the position of the switches 16, which are only shown schematically, can be pushed through the printing machine 01 along different drawing-in paths.
- the pull-in means 12 is guided by guide rails, not shown.
- the drawing-in means 12 can be coupled to the beginning of the web of the respective paper web, so that the paper web is conveyed through the printing machine 01 by pulling back the drawing-in means 12 along the desired drawing-in path.
- the regulation of the electric motor 17 driving the bobbin 13 according to the first exemplary embodiment can also be applied to devices for drawing in, wherein a finite drawing-in means 12 from a bobbin (not shown) in the area of the roll changer (s) 04; 06; 07 on a bobbin 13 behind the outlet of the printing units 02; 03 is rewound and vice versa.
- the individual units for. B. the cylinders of the printing units individually or in pairs, the entire printing unit or the printing unit, the driven rollers of the paper guide, the folder, and possibly other rotatable parts the printing press each has its own drive motor.
- the coordination or synchronization takes place with a so-called “virtual master axis” or “electronic shaft”, which electrically connects the regulation or control of the units to one another.
- a regulation (or control) of the electric motor 17 for the synchronous drive 14 or the direct drive of the coil former 17 is electrically connected to this “virtual leading axis”, for example in such a way that a speed of the pull-in means approximately the respective surface speed of the web contacting units, e.g. the corresponding cylinder of the printing units 02; 03, the driven paper guide or drawing rollers (not shown), the roll changer 04; 06; 07 etc.
- the corresponding speed or angular speed for the electric motor 17 of the synchronous drive 14 or the coil former 13 is determined in an electronic circuit or computing unit, possibly using a controllable frequency converter, and applied to the electric motor 17.
- a, possibly constant, pull-in speed can also be specified, the other units, which relate to the pull-in process, being driven via the electronic shaft with a corresponding peripheral speed.
- the change in the effective diameter must be superimposed on the desired or required retraction speed as described.
- the exemplary embodiment for the regulation of the electric motor 17 with respect to a moment aims at limiting the load on the web or the connection between the web and the pulling means 04 during the pulling in.
- the regulation takes place here in the case of a directly driven coil body 13, as already partially explained above, taking into account the changing diameter. This is taken into account, for example, in an electronic circuit or arithmetic unit by means of stored functions (for example depending on the revolutions or angles that have taken place or on the basis of the abovementioned measured values).
- the angular velocity or rotational speed can be determined on the bobbin or on the electric motor 17 (e.g. by means of an incremental encoder), and, as in the above-mentioned example, the controls or regulations of other, individually driven units are specified via the electronic shaft after corresponding conversion.
- the determination of the retraction speed can, however, also take place in a different way on the retraction path.
