Definitions
- the present invention relates to a method for operating a processing roller, a computing unit, a corresponding computer program and a corresponding computer program product.
- Cross-processing applications i. Applications in which, for example, a material web is cut through by means of a rotary cutter are known in general.
- Another example of cross-processing applications are transverse sealing devices, transverse perforating devices and cross-punching devices.
- Section length is not necessarily identical to the circumference of the cross-machine roller used.
- suitable laws of motion for the cross-processing roller can be achieved that during processing a typically material web synchronous cut and the rest of the time a so-called compensating movement is performed.
- This compensation movement serves a shorter or longer Format (section length) to reach as the so-called synchronous length, which corresponds to the circumference of the Qube processing roller.
- a method for operating a cross-processing roller is described in DE 10 2007 034 834 A1.
- An energy saving balance movement can accordingly be achieved if the compensation length, i. the part of the circumferential length of the cross-processing roller that can be used for the compensating movement, based on a synchronous range (Bexeich synchronous tangential speed of the roller and
- Movement speed of the material is determined.
- the compensation movement comprising braking, reverse rotation and acceleration of the roller can thus be carried out within the greatest possible limits.
- the synchronous area for cross cutters is defined so that the cut takes place exactly in the middle of the area. Enlarging the synchronous area on both sides ensures a clean insertion and removal of the blade into and out of the material. If the cross cutter is allowed to oscillate to the edge of the synchronous range, it is ensured that the knife will not dip into the material passing below the cross cutter during the pendulum process.
- slitters or Slot first defines the length of the slot to be created the synchronous area. This does not necessarily have to correspond to the length of the knife used. By enlarging the synchronous area on one side, it is possible to ensure a clean insertion or removal of the knife into or out of the material. Since slots are used with individual sheets which are at a defined distance from each other, slits of arbitrarily smaller length than the knife length can be cut with only one knife if the unused portion of the knife before or after the bottom edge of the knife Slotters happens. Compensating movements comprising a controlled reverse rotation of the processing roller are not known for slitters in the prior art.
- the present invention proposes a method, a computing unit, a computer program and a computer program product with the features of the independent claims.
- Advantageous embodiments are the subject of
- a circumferentially extending processing length or cutting length is defined along which the tool during machining with the material to be machined engaged. Furthermore, a compensation length or pendulum length is specified in the circumferential direction, along which a compensating movement of the processing roller is executable or executed, wherein the
- Tangential Marie of the processing roller is at least temporarily negative.
- the compensation length is determined on the basis of the circumferential length, the machining length and the tool length.
- the compensation length describes at least the one for
- the acceleration and / or deceleration process may also use the compensation length. However, it is also possible that the acceleration and / or deceleration length differ from the compensation length.
- the invention teaches, in particular, to take into account the tool length when determining the compensation length.
- the solutions for cross cutters known in the prior art only the cutting length or the synchronous range (range of synchronous tangential velocity of the roll and
- Machining rollers suitable in which the cutting length is not equal to the tool length, i. a part of the tool already passes bottom dead center without being in engagement with material.
- the invention offers the possibility to carry out energy-optimized movements and thus use lower-power and thus cheaper to buy and maintain drives, converters, etc.
- the compensation length is determined on the basis of a cutting length comprehensive synchronous range.
- the synchronous range i. the range of synchronous tangential velocity of the roll and the speed of travel of the material are increased beyond the working length. Since the synchronous range within the machine control is known, but not necessarily the machining length, the method can be easily implemented in this way.
- the compensation length is determined as the difference between the circumferential length and the sum of the tool length and a portion of the machining length or the synchronous range not lying within the tool length.
- the maximum available length can be used for the compensation movement, so that there is a particularly energy-saving solution.
- the backward movement can thus (in the limit) exactly to the tool. This allows maximum stopping and acceleration paths, resulting in a significant reduction of the maximum occurring accelerations.
- the compensation length is determined as the difference between the circumferential length and the sum of the machining length or the synchronous range and twice a portion of the tool length that is not within the machining length or the synchronous range.
- the machining length or the synchronous area is extended in both directions by the protrusion of the tool length.
- the processing roller may execute any compensation movement laws. These can be selected in such a way that the lowest possible energy consumption arises.
- the energy consumption can be determined or estimated, for example, based on the square of the acceleration of the drive and / or the roller. This makes it possible to minimize energy loss, thereby minimizing energy costs.
- the different laws of motion can also be optimized according to different criteria.
- criteria for example, the energy consumption of Compensation movement, which is particularly small, for example, in the description of the movement of the roller by means of a 3rd degree polynomial.
- polynomials of the third degree or sinoids prove to be advantageous.
- Modified sine lines for example Bestehorn smus lines with low jerk characteristic values, are suitable for this purpose.
- the applicable laws of motion can be selected, for example, energy-optimized, in which case, in particular, heating, energy consumption and motor or amplifier size can be taken into account.
- the laws of motion used can be optimized for the maximum moment, e.g. the maximum speed of the feed or the drive or motor or amplifier size.
- the selected law of motion can also be optimized to protect the mechanics, which, for example, a lower noise is feasible.
- the compensation length is additionally determined on the basis of a material length.
- the material fed to the slitter or slitter lies usually already present in isolated bows.
- the machine configuration typically provides that the leading edge of each sheet reaches the bottom dead center of the slotper at a defined centerline position (eg, 0 °). Bows can be larger than that
- Run length of the leading axis which is typically the size of the heaviest and most non-dynamic machine component - e.g. Impression cylinder, rotary die cutter, ... - corresponds. This means that a new arc does not always start for each master axis cycle. From the given values "iieicachspositiön, where the arc reaches the slotter", "development length of the leading axis” and “material length” can be determined in which area of the Leitachsposition no material is in the engagement area of the slotter. This information can be used in the calculation of the compensation movement, so that in areas where there is no material in the engagement area of the slotter, the compensation length can extend into the synchronous area of the cut and beyond. This is due to lower acceleration and deceleration values dynamic and energetically more efficient than the oscillation up to the maximum at the beginning of the machining length or the synchronous range.
- An arithmetic unit according to the invention is, in particular programmatically, configured to perform a method according to the invention.
- the invention additionally relates to a computer program with program code means in order to carry out all the steps in accordance with a method according to the invention when the computer program is executed on a computer or a corresponding arithmetic unit.
- the inventively provided computer program product with program code means which are stored on a computer-readable data carrier is designed to perform all steps according to a method according to the invention when the computer program is executed on a computer or a corresponding computing unit.
- Suitable data carriers are, in particular, floppy disks, hard disks, flash memories, EEPROMs, CD-ROMs, DVDs, and the like. It is also possible to download a program via computer networks (Internet, intranet, etc.).
