Definitions
- the invention relates to methods for waxing a roll of material according to the preamble of claim 1 or 12.
- stripping devices for example stripping rings, are present on known roll changers.
- WO 02/40387 A1 describes a device for producing sleeveless paper rolls, in which the two trunnions are withdrawn simultaneously to change the paper roll.
- the invention has for its object to provide methods for waxing a roll of material.
- the object is achieved by the features of claim 1 or 12.
- the first stripping device is pressed against the material roll with a first stripping force, with no relative movement between the material roll and the axle journal initially occurring due to the fixed distance between the roll arms of the roll changer. Then, in the second process step, the roller arms are moved apart until the first side of the material roll is stripped from the first axle journal. The correct wiping of the first side of the material roll from the first axle journal is ensured by the wiping force A of the first wiping device.
- the second stripping device is then pressed against the roll of material with a second stripping force.
- the second side of the material roller is then also stripped from the second journal.
- the second stripping force B is greater than the first stripping force A. This can be advantageous if the roll of material has not yet been completely used up and thus hangs on one side from the first axle journal after stripping the first side. Due to the tilting moment that occurs, the frictional forces between the second side of the material roll and the second axle journal are increased, so that one correspondingly higher second stripping force B is required for stripping the second side of the material roll from the second journal.
- tensioning devices for fixing the material roll are provided on the axle journals, for example in the form of clamping jaws, these should not simply be opened at the same time before the material roll is axed. Rather, only the tensioning device on the first side of the material roll should initially be opened, so that the second side of the material roll is initially still fixed and cannot come loose from the second journal. Only after the first side of the material roll has been completely stripped off from the first axle pin will the second tensioning device also be opened, so that the second stripping device can strip off the second side of the material roll.
- the manner in which the first scraper device is fixed in the end position is basically arbitrary.
- a particularly simple manner results from the fact that the first stripping device is pressed against an end stop with a fixing force C for fixing in the end position.
- a device for applying the Fixing force C must be present on the first stripping device anyway, for example in the form of a pneumatic or hydraulic actuating cylinder, and an end stop is also regularly present anyway.
- the fixing force C is greater than the second stripping force B, so that the first stripping device cannot be pushed back when the second stripping device is extended.
- the weight of the roll of material tilts downwards with its first side from the second journal when it is waxed down.
- This tilting of the material roll can damage the second stripping device.
- a tilting of the material roll causes a considerable force load on the second stripping device, which the latter is often not able to cope with.
- the scraper device is designed, for example, in the manner of a scraper ring which is extended by several actuating cylinders in the direction of the longitudinal axis of the material roll, the tilting of the material roll can often cause the push rods of the actuating cylinders to bend.
- the second stripping force B assumes two values in the respectively assigned phases of the waxing-up, the values of the stripping force B ⁇ and B 2 being maintained consistently during the successive phases.
- the material roll generally tilts when the material roll is essentially completely stripped off a cylindrical part of the second axle pin and only rests on the conical end of the second axle pin.
- the two successive phases for applying the second stripping force B should therefore be oriented at the transition between the cylindrical part of the second journal and the conical part of the second journal.
- a suitable means of transport can be used to remove the roll of material after waxing without manual intervention.
- this means of transport is arranged below the material roll before the material roll is stripped from the first axle journal or before the material roll is braced from the second axle journal. In this way, the means of transport can pick up the finished material roll and then transport it back to the material warehouse or dispose of an empty material roll.
- the tilting of the roll of material after the unilateral axis can be avoided in a simple manner by providing a height-adjustable support unit on the transport means.
- This support unit can, for example, in the manner of a Scissor lift table be formed. Before and / or during the waxing of the material roll, the support unit is approximated or placed on the circumference of the material roll, so that the one-sided tipping of the material roll is correspondingly reduced or avoided entirely.
- a suitable drive device for example a chain conveyor arranged under the floor, can be provided for the automatic movement of the transport means. It is particularly advantageous if a coupling device is provided between the transport means and the drive device, so that the coupling device can be uncoupled under the material roll after the transport device has been arranged in the correct position. The result of this is that, after contact with the material roll, the transport means can follow all longitudinal movements of the material roll during the waxing-up, so that damage to the circumference of the material roll due to an undesired relative movement between transport means and material roll is excluded. In addition, the optimal position of the material roll on the transport means is easily maintained during the waxing down.
- Figure 1 shows a schematically illustrated reel changer in a first phase of a material reel
- FIG. 2 the reel changer according to FIG. 1 in a second phase of the waxing up
- FIG. 3 shows the reel changer according to FIG. 1 in a third phase of the waxing-up;
- FIG. 4 shows a diagram of the pressure forces on the stripping devices of the roll changer according to FIG. 1 during the various phases of the waxing.
- a reel changer 01, z. B. a web-fed rotary printing press with two roller arms 02; 03 shown.
- a first axle pin 04 and a second axle pin 06 are provided on the first roller arm 02 and are inserted into a cylindrical recess 07 of a material roller 08 on the second roller arm 03.
- the material roll 08 can be rotatably mounted on the roll changer 01.
- the clamping devices 09 are designed in the manner of clamping jaws 09 and can be actuated on the roller arms 02; 03 are pressed against the inner circumference of the cylindrical recess 07.
- the roll changer 01 has a second pair of roll arms, not shown, for receiving a second material roll and / or residual roll, which is preferably identical to the first pair of roll arms 02; 03 are trained.
- the two roller arms are pivoted about a pivot axis.
- the clamping devices 09 have elements that can be moved in the radial direction.
- the clamping devices 09 can be radially expanded by the clamping jaws 09.
- first wiper device 11 is provided on the first roller arm 02 and a second wiper device 12 is provided on the second roller arm 03.
- the two stripping devices 11; 12 are both in the manner of scraper rings 11; 12 and can be pressed against the end faces 14 of the material roll 08 by means of pneumatic actuating cylinders 13 (see FIGS. 2 and 3). Proceed as follows to axis the material roll 08 from the roll changer 01:
- the first stripping device 11 is pressed with a first stripping force A against the left end face 14 of the material roll 08. Then the tensioning device 09 on the first axle 04 is opened. The first roller arm 02 is then moved outwards in the direction of the movement arrow 16 in order to ax the first axle journal 04, in order in this way to increase the distance between the roller arms 02 and 03. Since the right side of the material roll 08 is fixed by means of the tensioning device 09 of the second axle pin 06, the first axle pin 04 is pulled out of the cylindrical recess 07 by moving the roller arms 02 and 03 apart. This pull-out movement is supported by the extension of the first stripping device 11 with the first stripping force A, so that the undesired pulling off of the right side of the material roll 08 from the second axle pin 06 is excluded.
- Fig. 2 the material roll 08 is shown after the left side has been axed from the first journal 04. It can be seen that the first stripping device 11 is now fully extended. In this end position, the stripping device 11 is fixed by acting on the actuating cylinders 13 , 13 with a higher operating pressure, for example 6 bar. This prevents undesired pushing of the left side of the material roll 08 onto the first axle pin 04 during the further axle-off.
- a means of transport 17 is arranged below the material roll 08 in order to be able to remove the material roll 08 after it has been axed.
- the second stripping device 12 is then subjected to the initial value B of a second stripping force B and the tensioning device 09 of the second axle pin 06 is opened. Due to the stripping force B exerted by the stripping device 12, the material roll 08 is first pressed against the fixed stripping device 11. Then the second Move the roller arm 03 to the right in accordance with the movement arrow 18 in order to further increase the distance between the roller arms 03 and 02. Corresponding to the greater distance between the roller arms 02 and 03, the right side of the material roller 08, supported by the extension of the second stripping device 12, is stripped from the second axle pin 06.
- the stripping force B of the second stripping device 12 is reduced to the final value B 2 , so that the frictional force between the end face 14 and the stripping device 12 is reduced and damage to the Actuating cylinder 13 is excluded when the material roll 08 tipping.
- Fig. 3 the material roll 08 can be seen after the complete waxing.
- the full roll of material 08 lies on the transport means 17 and can now be automatically transported away from the roll changer 01.
- the drive pressures of the stripping devices 11; 12 schematically shown during the waxing of the material roll 08.
- the drive pressure of the first stripping device 11 is shown with a solid line and the driving pressure of the second stripping device 12 with a dashed line.
- the first stripping device 11 is subjected to an overpressure of 1.5 bar when the left side of the material roll 08 is axed, in order to generate the stripping force A in this way. After the left side of the material roll 08 has been completely wiped off, the first wiping device 11 is then subjected to an overpressure of 6 bar in order to generate the fixing force C.
- the second stripping device 12 is initially depressurized. Only after the first stripping device 11 has been fixed with the fixing force C does the second stripping device 12 become attached a pressure of 3 bar to generate the initial value B ⁇ of the second stripping force B. In the second phase of stripping the right side of the material roll 08, the pressure of the second stripping device 12 is then reduced to 1.5 bar gauge pressure, which corresponds to the end value B 2 of the second stripping force B.
