Definitions
- the invention relates to a winding roll according to the preamble of claim 1 and a winding machine for the continuous winding of a material web, in particular paper or cardboard web, on a spool to a winding roll according to the preamble of claim 9.
- Methods and winding machines of the type mentioned here are related with a machine for the production or processing of a material web, for Example paper or cardboard web used.
- a winding machine proposed (DE 197 35 590.0), in which the material web over a peripheral region of a pressure drum is guided with a winding roller forms a winding gap.
- the diameter increases the winding roller by a relative movement of the winding roller relative to the Pressure drum balanced and the line force in the winding gap by a shift the pressure drum controlled.
- To prepare a drum change a new drum in a primary area above the pressure drum brought in. There is a winding gap between the new drum and the pressure drum due to a relative movement between the pressure drum and the new drum educated.
- the material web is separated and its free end on the new one Reel wound.
- the new drum comes with the newly created winding roll over a circumferential area of the pressure drum into a lower-lying secondary area transferred.
- the winding in the primary area and during the transfer becomes a compensation of the increasing winding roll diameter and the Control of the line force in the winding nip realized by moving the pressure drum.
- the diameter increase of the winding roll is again by a relative movement of the winding roll with respect to the pressure drum a guide track balanced and the line force in the winding gap through again controlled a shift of the pressure drum. It has been shown that the setting the line force during winding in the primary area is not always sensitive enough is possible, which has an adverse effect on the winding quality.
- the procedure provides that during the current Winding process the material web guided over a peripheral region of a pressure drum through a winding gap between the pressure drum and a winding roller led and wound on this.
- the pressure drum is pressed against the winding roll, with a control or regulating the line force in the winding gap by moving the pressure drum he follows.
- a desired diameter of the winding roll and The pressure drum becomes the necessary preparation for a drum change in a fixed position, in which the bearing of the pressure drum temporarily is fixed. This can e.g. in such a way that the contact with the winding roll under Maintaining the desired line force is maintained.
- the weight of the pressure drum is both greater than that of an empty drum also that of a winding roll with only a few winding layers.
- the one for control or regulation of the line force in the winding nip to move mass of the winding roll The start of the winding process is therefore relative to the mass of the pressure drum low, so that a particularly sensitive one, especially during the winding process Setting the line force is possible.
- This in turn enables an optimal one Core winding and thus a defined structure of the winding roll, which results in the winding result is improved. Only after the winding roll in the secondary area has been transferred, there is a change in the tax movement for hiring the line force instead.
- the stationary storage of the Press drum released so that they are shifted to adjust the line force can, preferably during the balancing of the increasing winding roll diameter by a relative movement of the winding roller with respect to the pressure drum is carried out because namely in the manufacture of very large winding roll diameters the usual maximum stroke distance of moving the pressure drum for one stationary storage of the winding roll is usually not sufficient.
- a good winding result that is a Winding roll can be achieved with a defined, uniform winding hardness, because a Fine adjustment of the line force in the winding gap between the pressure drum and the Winding roll during the start of the winding process and when transferring the reel in the secondary area is possible.
- a winding machine with the features of the claim 9 suggested.
- This includes a pressure drum, which by means of a pressure device - preferably horizontally - is shiftable. Over a circumferential area the pressure drum is a material web, in particular a paper or Cardboard web, guided on a spool and wound up into a winding roll. Of the Drum forms a winding nip with the pressure drum through which the material web to be led.
- the winding machine also has a new reel primary storage, with the help of the new drum along a first Guideway is radially displaceable to the pressure drum, as well as a secondary bearing for the drum.
- the pressure drum is when the drum is in the primary storage is temporarily fixable in a fixed position and it is when the drum is in the secondary storage by means of the pressure device - preferably horizontally or essentially horizontally - displaceable.
- the line force in the winding gap during winding in The primary area is particularly sensitive due to a shift of the drum from the beginning only a few layers of winding roll relative to the temporarily fixed Pressure drum can be set. A particularly good core winding of the Tambours possible, which in turn increases the quality of the winding roll.
- the line force is controlled again in the secondary area according to DE 197 35 590.0.
- Figures 1 to 5 each show a highly schematic schematic diagram of an embodiment a winding machine 1, which is used for winding one in the following paper web generally referred to as material web 3 serves on a reel.

- the pressure drum driven by a drive, preferably a center drive 5 is rotatably held on a guide carriage 8 which on a horizontal guide 9 is movable.
- the hydraulic in this embodiment Piston / cylinder unit designed pressing device 6 includes a in a cylinder 11 guided piston 13, which engages with the guide carriage 8 Piston rod 15 is firmly connected.
- Cylinder 11 becomes the guide carriage 8 and thus the pressure drum 5 in Figure 1 shifted to the right in the direction of an arrow 19.
- Cylinder 11 becomes the guide carriage 8 and thus the pressure drum 5 in Figure 1 shifted to the right in the direction of an arrow 19.
- moving in the piston rod 15 in the cylinder 11 is a displacement of the pressure drum 6th to the left in Figure 1.
- the winding machine 1 further comprises a primary bearing 21, the two pivot levers 23 comprises, of which only one is shown in Figure 1.
- the swivel levers 23 are around a stationary one that extends perpendicularly into the image plane of FIG Swiveling axis.
- a holding device 25 is attached to the pivot levers 23, which with the aid of a primary pressure device shown only symbolically with an arrow 72 is displaceable relative to the pivot levers 23.
- the holding device 25 is used for rotatably holding and guiding a reel.
- the winding phase shown is an empty drum 27 from the holding device 25 in a distance from the pressure drum 5 held ("standby position").
- the primary pressure device (arrow 72) is the one in FIGS. 1 to 5 illustrated embodiment a piston / cylinder unit, the structure - at least essentially - that of the pressing device 6.
- you can to move the holding device 25 relative to the pivot levers 23 also Spindle drive or the like can be used.
- On the function of the Primary bearing 21 is discussed in more detail below.
- the winding machine 1 further comprises a secondary bearing 31, which is arranged horizontally Rails 33 and a transport device movable by means of a lifting device 35 37 includes.
- the lifting device 35 is formed here by a spindle drive, which comprises a threaded spindle 41 driven by an electric motor 39.
- the transport device 37 serves to hold and guide one on the rails 33 overlying drums; in the winding phase of a drum shown in Figure 1 43, on which a winding roll 45 is wound.
- the secondary bearing 31 is a a symbol indicated, hereinafter referred to as secondary drive 47 Center drive assigned to that of the secondary storage or Transport device 37 drives the drum 43.
- the secondary drive 47 is in a known manner together with the transport device 37 parallel to the Rails 33 relocatable.
- the drum 43 is arranged in a secondary area in FIG.
- Secondary area is the part of the winding process in which the winding roll on the Rails 33 of the secondary bearing 31 rests and optionally along this a second linear guideway is shifted; in this embodiment along the line G.
- the pressure drum 5 by means of the pressure device 6 defines the scope of the wound on the reel 43 Winding roll 45 pressed, whereby a winding gap is formed.
- the material web 3 is passed over a peripheral region of the pressure drum 5 and onto the winding roll 45 wound up.
- the line force (arrow L) in the winding gap between the pressure drum 5 and the one lying on the rails and guided by the transport device 37 Winding roll 45 is 5 in by a displacement movement of the pressure drum Direction of the double arrow 7 set or optimized. For this is at a control device 49 is provided in this exemplary embodiment.
- the pressure drum 5 is only relatively slightly in the direction of the double arrow 7 shifted from its central position, in which the piston 13 of the pressing device 6 is located approximately in the middle of the cylinder 11.
- the pressure drum 5 points towards the winding roll, which becomes heavier with increasing diameter 45 less weight, so that a change in the direction of displacement the pressure drum 5 can be carried out very quickly. So you can for example, changes occurring due to an imbalance of the winding roll itself Jumps in line force can be compensated for quickly, so that a winding roll with a defined winding hardness or an even winding hardness curve can be formed.
- the control device 49 described below is especially suitable for one hydraulic system and is in another - in the figures not shown - embodiment of the pressing device adapted accordingly or modified.
- the control device 49 here comprises a measuring device 51 for the line force L, a controller 53 and a setpoint generator 55.
- the measuring device 51 is connected to the controller 53 via a measuring line 57.
- the control device 49 comprises a first valve 59 which can be switched into two functional positions In the first functional position shown in FIG. 1, the valve 59 connects one of the Regulator 53 line 61 coming with cylinder 11.
- the pressure of line 61 Hydraulic fluid present is set by controller 53 and is smaller than that maximum pressure provided by a pressure source 63.
- the maximum pressure of the hydraulic system is also present in a bypass line 65 which bypasses the controller 53.
- the cylinder 11 of the pressing device 6 pressurized with the maximum pressure of the hydraulic system.
- the Control device 49 also includes a second valve 67, which has two functional positions is switchable. In a second functional position, line 61 is connected via a Line 69 with the cylinder of the primary pressure device shown only symbolically (Arrow 72) connected ( Figure 2). In the first functional position of valve 67 (FIG. 1) becomes the connection between line 61, in which the for setting the line force required pressure set by the controller 53 is present, and the primary pressure device (Arrow 72) interrupted.
- the Controller 53 then the pressure of the hydraulic fluid in line 61 and thus in Cylinder 11 such that the measured value of the line force approaches the target value.
- the line force can then also be constant, for example constant Value is maintained if a fault occurs in the winding process.
- a malfunction can be caused by an inaccurate movement of the transport device 37, so that the position of the pressure drum 5 and the winding roller 45th formed winding gap shifts slightly.
- the balance of the growing Diameter of the winding roller guided and held by the secondary bearing 31 45 is during this winding phase by a process of Transport device 37 in the direction of arrow 19 by means of the lifting device 35 realized.
- the cylinder 11 is the Pressure device 6 with the maximum pressure of the hydraulic system or the pressure source 63, while the cylinder of the A lower pressure is applied to the primary pressure device (arrow 72), namely the pressure prevailing in line 61 for setting the line force in new winding gap.
- the primary pressure device arrow 72
- the empty, from the Primary storage 21 held and by the primary drive at web speed Accelerated drum 27 is from its standby position shown in Figure 1 shifted to the so-called primary position, i.e. defined against the Circumference of the pressure drum 5 pressed; this is done using the in the figures an arrow 72 shown primary pressure device.
- the drum 27 held by the primary bearing 21 from Primary drive 29 driven.
- the controller 53 the pressure in the line 61st changes accordingly.
- the drum 27 is already in the Secondary region arranged, that is, the drum 27 lies on the rails 33 the secondary storage 31. Until the drum 27 with the wound on it Transfer winding roll 71 from the primary bearing 21 to the secondary bearing has been, the pressure drum 5 remains fixed in its starting position, because the cylinder 11 of the pressure device 6 continues at the maximum pressure of Hydraulic system is connected. In Figure 3, the finished winding roll 45 is already from the Secondary storage 31 was removed after it was braked and by Secondary drive 47 was separated.
- FIG. 6 shows a diagram in which the line force or the pressure L in the winding gap between the pressure drum and the winding roll, the pressure in the cylinder of the pressure device 6 and the pressure prevailing in the cylinder of the primary pressure device are plotted before, during and after a reel change.
- the pressure p is plotted on the ordinate axis and the time t is plotted on the abscissa axis.
- the solid line L shows the pressure L in the nip between the winding roller and the pressure drum.
- the course of the pressure p Z11 in the cylinder 11 of the pressure device 6 is shown with a dashed line and the pressure p PA in the cylinder of the primary pressure device (arrow 72) is shown with a dash-dotted line.
- the pressure L that is to say the line force in the winding gap, has an essentially constant value here purely by way of example.
- the line force is again controlled or regulated exclusively by adjusting the pressure in the cylinder 11 of the pressing device 6, so that the pressure in the nip between the winding roller and the pressing drum increases slightly.
- the pressure in the cylinder 11 is slightly reduced again and thus the pressure L in the winding gap.
- the reason why the pressure p Z11 at point 3 has not been reduced to the pressure p PA in the cylinder of the primary pressure device is that a decrease in the pressure in the winding gap is to be prevented during the transfer of the reel from the primary bearing to the secondary bearing .
- both drives that is the primary drive 29 and the Secondary drive 47, coupled to the drum 27. This ensures that the reel with an exact, adjustable during the entire winding process Torque (drive / braking torque) can be applied.
- the winding machine described with reference to Figures 1 to 5 is generally for winding a material web can be used.
- the winding machine can end at one Machine for manufacturing or processing, for example finishing, a material web, for example a paper or cardboard web, to be arranged around the wind the finished material web into a winding roll.
- the winding machine can also be used to rewind already wound winding rolls.
- the almost finished winding roller 45 in guided by the secondary bearing is used
- Direction of the arrow 19 to the right into an example in FIG. 2 with a broken line Move the position shown before the material web 3 onto the empty drum 27 is transferred.
- the pressure roller serves to to prevent air being carried in between the winding layers of the winding roll 45, for example, when the web of material moves freely from the pressure drum 5 is guided to the winding roll 45.
- the contact pressure with which the pressure roller is pressed on the circumference of the winding roll 45 is adjustable.
- the pressure roller can are preferably driven by a drive, for example a center drive before and during the pressure roller to the extent of the secondary storage held winding roll 45 is pressed.
- the formation of a space between the almost finished winding roll and the The pressure drum before changing the drum creates space, for example, for one Separating device for separating the material web into the area between the new one Tambour, the pressure drum and the almost finished winding roll. It is also possible, from below a medium flow, for example air flow, in the Conduct intermediate space, while braking the almost finished winding roll leads to the formation of a material web loop. In the area of the loop, the Material web are separated by means of the separating device. It goes without saying a "Nordic change" is possible, that is, the material web loop is in the nip wrapped between empty drum and pressure drum. Then the tears Material web from. Such methods and devices for separating the material web are generally known, so that they are not discussed in more detail here.
- the method according to the invention is also described in DE 197 37 709.2 Winding machine realizable, which is based on a similar structure to that 1 to 5 of the winding machine described.
- the new drum is already on the rails of the secondary storage before a winding gap is formed between the empty drum and the pressure drum and the material web is transferred to the empty reel. With this winding machine the reel is fed along a straight guideway shifted.
- the content of DE 197 37 709.2 is hereby Made the subject of this description.
