Description

The invention relates to a method for winding a continuous web of material, in particular Paper or cardboard web, according to the preamble of the claim 1 and a winding machine for continuous Winding a web of material, in particular Paper or cardboard web, according to the preamble of the claim 12th

A winding machine is known from EP 0 697 006 B1 of the kind mentioned here, the one on a vertically displaceable lifting table arranged pressure drum. A continuously incoming material web, for example paper web, is over a perimeter of the too referred to as the back-up roller or support drum led and on a drum to one Winding roll wound up. The pressure drum on the circumference of the winding roll is pressed and with this forms a winding gap, is during the entire winding process below a horizontal Guideway arranged along which the initially empty drum and after the separation and Transfer of the material web this with the on it wound winding roll is guided. For preparation a change of drum turns the pressure drum move vertically upwards and at the same time the almost finished, until then stationary in one Winding position held along the Guideway in the direction of a finished winding position relocated. Meanwhile the line contact remains between the pressure drum and the almost finished one Winding roll exist. The pressure drum is on the Extent one from a waiting position into a Shifting position shifted along the guideway empty drum pressed and forms with this a second winding nip. After that the material web is separated, whose free end wrapped on the empty reel and the finished winding roll is shifted horizontally in such a way that the contact between this and the pressure drum will be annulled. To transfer the new winding roll from the winding position to the The pressing drum is vertical down and the new winding roll along the Guideway shifted. The new winding roll rolls over a peripheral region of the pressure drum ab, that is, the winding gap remains during the transfer of the new winding roll into the winding position exist and migrate over a circumferential area the pressure drum. After the new Winding roll has reached the winding position and in this is fixed, becomes the bigger one Winding roll diameter by a vertical Compensated downward movement of the pressure drum. The The pressure drum is thus used during the entire winding process from below to the circumference of the winding roll pressed and must therefore part of the winding roll weight wear. Due to the deflection of the drum with the winding roll wound on it the line force in the winding gap over the web width uneven, causing the quality of the finished Product is reduced. Furthermore, fluctuations occur in line force while the new one Winding roll from the winding position to the winding position is transferred, i.e. over the circumferential area the pressure drum moves. This too can Fluctuations in the line force lead and thus Discontinuities in winding hardness or Winding hardness course, which also results in winding is affected in an undesirable manner. Furthermore, it has been shown that the vertical Process of the pressure drum to influence the Line force requires a complex control is. Nevertheless, in many cases the line force not set precisely enough Jumps and fluctuations in line force, for example caused by an imbalance in the winding roll are not set with sufficient accuracy become.

It is therefore an object of the invention to provide a method and to create a winding machine that this Do not have disadvantages.

A method is used to solve this problem the features of claim 1 proposed. This is characterized in that the continuously incoming material web over a peripheral area a pressure drum is guided, which with a in a winding position rotatably held winding roll forms a winding gap. For preparation a drum change is preferably vertical, but at least essentially vertically displaceable Move the pressure drum down, so lowered. Then the almost finished winding roll from the winding position towards a finished winding position and an empty drum from a waiting position towards the angular position along a preferably horizontal, but at least in essentially horizontal guideway. The pressure drum is now raised, that is shifted vertically upwards and a winding nip between the pressure drum and the empty drum a horizontal or essentially horizontal Relative movement of the pressure drum against that empty drum formed. The position of the pressure drum compared to the empty drum is like this chosen that the winding gap in an imaginary, horizontal plane at the center the pressure drum is, or below this level is formed. Finally the Material web separated, the free end of the empty drum transferred and wound up.

When changing the drum, the pressure drum So moved to a position where the empty one Drum - seen in the horizontal direction - this can happen without these in contact with each other come. Only then is the pressure drum raised and by a horizontal relative movement compared to the empty drum with defined force pressed on its circumference and a winding gap is formed. The position of the pressure drum chosen over the empty drum in such a way that the center point - seen in the vertical direction - at least at the same level or above the The center of the empty drum is located. Thereby it is ensured that only on the pressure drum the forces act through the pressure the pressure drum to the circumference of the drum or the winding roll wound on it be formed. In other words, during the Wrapping does not become part of the dead weight the winding roll (as in the prior art) carried by the pressure drum. Hence the Deflection of the winding roll practically none, at least but only very little influence on the line force in the winding nip. It is therefore possible a uniform line force across the web width adjust, which achieves a high winding quality can be. By preferably -in vertical Direction seen - constant position of the winding gap during the entire winding process fluctuations and jumps in line force, as they are known in the - described above Winding machine during the transfer of the new winding roll in the winding position by the Unwinding of the winding roll over a circumferential area the pressure drum occur avoided. Furthermore is a compensation of those occurring in the winding gap Fluctuations and jumps in line force respectively the line force curve through the horizontal Relative movement of the pressure drum opposite the winding roll possible, especially because the pressure drum having a relatively large weight just moved and not raised or lowered needs to be. This is the line force sensitive enough adjustable, making a high winding quality can be achieved.

In an advantageous embodiment of the method it is envisaged that the winding gap between Press drum and empty drum only then formed when the empty drum is in the winding position is arranged. Before the winding nip formed the empty reel from the waiting position transferred to and in the winding position kept stationary. In connection with the present Invention is understood to be "stationary" that a rotation of the drum around its Longitudinal axis is possible and a translational movement of the drum is prevented. The control the displacement movements of the winding roll and the Pressure drum from the start of the winding process to Finishing the winding roll is relatively easy, ensuring that at every stage of the Winding process a defined line force in the winding gap is adjustable. In a further variant the process becomes the winding nip between the pressure drum and empty drum during the relocation of the empty drum from the Waiting position formed in the winding position. Thereby can change the drum in a very short time be carried out so that the number of winding layers, the while the web of material in a free Train from the pressure drum to the almost finished winding roll led and wound up on this, are low.

Advantageous embodiments of the method result from the remaining subclaims.

To solve the above-mentioned problem, a Winding machine for winding a continuously incoming material web, especially paper or Cardboard web, on a reel to a winding roll proposed that mentioned in claim 12 Features. The winding machine includes one preferably vertical, but at least essentially vertically displaceable lifting table, on one preferably driven pressure drum rotatable is arranged. There is also a tour for the reel provided at least two in one Distance from each other, parallel or essentially arranged parallel to an imaginary horizontal Includes guide rails along which the Drum is movable. The winding machine draws characterized in that a transport device on the lifting table is provided on which the pressure drum is rotatably arranged and that the Transport device on the lifting table by means of a Lifting device horizontally or essentially horizontally is relocatable. This is a quick one Compensation of occurring in the winding gap Fluctuations and jumps in line force respectively of the line force curve possible because the The pressure drum is not lifted vertically or must be lowered, but only needs to be moved horizontally.

An embodiment is particularly preferred the winding machine, which is characterized by that the pressure drum rotatable on one of the transport device movable guide carriage is held by means of a pressure device horizontally or essentially horizontally is relocatable. The vertically movable Lift table is therefore only used during of a drum change a passing an empty one To allow drums to come from a waiting position is transferred to the winding position. The increasing diameter of the in the winding position stationary winding roll is used in this Embodiment by a compensating movement the pressure drum through a horizontal Relocation of the transport equipment realized is compensated while maintaining the line force in the winding gap by a relative movement of the Pressure drum against the winding roll by a Controlled horizontal displacement of the slide becomes. To automate the wrapping process, can the relative movement of the pressure drum to adjust the line force using suitable Means are also regulated.

Further advantageous exemplary embodiments of the winding machine result from the other subclaims. The drive type described in claim 18 is related to another Winding machine known from US 5,251,835.

The winding machine described below is generally used for winding a material web. The winding machine can be at the end of a machine for manufacturing or finishing, for example Coating machine, a material web, for example a paper web, to be arranged wind the finished material web into a winding roll. The winding machine can also do this be used, a pre-wound, also referred to as a roll, to roll the winding roll.

Figures 1a to 1d each show a side view an exemplary embodiment of a winding machine 1, which is used to wind up a material web 3, for example a paper or cardboard web serves a drum. This can, for example, from a tubular roller with trunnions be, or from a sleeve by a winding rod will be carried. From Figures 1a to 1d goes a sequence of functional steps the Winding machine 1 out.

The winding machine 1 comprises a lifting table 5, the by means of a guide device 7, of which in FIG la only a guide 9 shown is vertical in the direction of a double arrow 11 displaced. On the lifting table 5 is also a Transport device 13 designated carriage, in the horizontal direction (double arrow 15) movable on a guide, not shown is attached to the lifting table 5. About the procedure the transport device 13 on the lifting table 5, a lifting device 17 is provided, which at this embodiment of a spindle drive is formed, which is driven by a motor 19 Includes threaded spindle 21. The design the lifting device 17 can in principle be varied and can also, for example, of a - preferably hydraulic piston / cylinder unit formed become. On the transport device 13 is a Guide carriage 23 arranged on a not shown second guide, which - at least partially - attached to the transport device 13 is, by means of a pressing device 25 in the horizontal Direction (double arrow 27) can be moved. The pressure device 25 is here as - preferably hydraulic piston / cylinder unit, the one guided in a cylinder 29 -not shown- includes pistons. On the piston a piston rod 31 attached to its other End with the slide 23 respectively connected to a bearing 33 mounted thereon is. The design of the pressure device 25 is variable, that is, with another Embodiment of the winding machine 1 can Pressure device 25, for example, from a spindle drive be formed.

Furthermore, one is also referred to as a pressure roller Pressure drum 35 is provided, which by means of Storage 33 held stationary on the carriage 23 is. The pressure drum 35 is with one a symbol represented drive 37, which here as Center drive is formed, driven, the stationary, i.e. in a fixed position on the Guide carriage 23 is arranged. With the help of Drive 37 can have an adjustable drive torque be applied to the pressure drum 35.

The winding machine 1 further comprises a guide 39 for a drum on which the material web 3 is wound up. The guide 39 comprises at least two at a distance from each other, parallel to one imaginary horizontal lines H arranged guide rails, of which in the representation according to the FIGS. 1a to 1d only the guide rail 41 is recognizable. In Figure la there is an empty drum 45 with its journal 43 and by means of not shown Bearings on the guide rails 41 of the Guide 39. In the shown in Figure la Winding phase is on a drum 47, which with its Journal 43 also on the guide rails 41 rests, the continuously tapering material web 3 wound into a winding roll 49. Of others are for guiding and holding a drum two bearings (not shown) known per se and transport devices are provided, which also as Primary and secondary storage are designated, by means of which a reel during the winding process movable along the guide rails 41 is. The primary and secondary storage can for example, a construction similar to that Have guide carriage 23.

Furthermore, a first drive 51 and a second Drive 53 provided, each with a Symbol are shown. Shown at in Figure 1a Winding phase are both drives 51, 53 that on opposite sides of the winding machine 1 are arranged with the in winding position (III) held drum 49 coupled. By means of the preferably drives designed as center drives 51, 53 can have a defined torque the winding roll or on the reel, on which the winding roll is wound, applied become. The drives 51, 53 are by means of Not shown relocation means independently from each other parallel to the guide rails 41 of the Guide 39 relocatable, that is, in the horizontal direction. In a particularly preferred embodiment the winding machine, which is characterized by a simple structure, is one of the Drives 51, 53 on one of the storage and transport devices kept stationary.

The stationary in Figures 1a and 1b in a winding position (III) held winding roll 49 forms with the pressure drum 35, over the circumference of the material web 3 is led in areas, a winding gap, which in this embodiment during of the entire winding process in an imaginary horizontally running - dash-dotted lines - Level E lies. In level E, the one standing perpendicular to the image plane of Figure 1a Spans the area, the center points of the in a pressure drum located in a raised position 35 and the resting on the guide rails 41 Drum 45, 47.

As can be seen from Figure 1a, the material web 3 of the winding machine 1 - in the direction of rotation Material web 3 seen (arrow 55) - upstream Manufacturing or processing machine first via a stationary inside the winding machine 1 arranged deflection roller 57 guided and by this to a deflection roller attached to the guide carriage 23 59, for example as an spreader roller is trained. From the pulley 59 the material web 3 of the pressure drum 35 is fed, over a peripheral region of the pressure drum 35 of guided about 180 ° and wound on the winding roll 49. The pressure drum 35 is by means of the pressure device 25 with a defined force pressed the circumference of the winding roller 49 so that a Winding gap is formed through which the material web 3 is performed. Which also as a clamping pressure respectively -kraft Designated line force in the winding gap is carried out by a procedure of the carriage 23, on which the pressure drum 35 is stationary is held on the transport device 13 controlled. In another embodiment the winding machine 1 is provided that the line force is regulated in the winding gap, that is, the line force is controlled automatically set to a desired value. For this purpose, only one is shown schematically in FIG. 1a shown control unit 61 provided on the will be discussed in more detail below. In both Cases, i.e. when controlling or regulating the line force, For this purpose, the pressure device 25 the guide carriage carrying the pressure drum 35 23 is assigned, influenced influenced. By moving the pressure drum 35 can Fluctuations in line force compensated for respectively be avoided so that continuously a desired winding hardness can be achieved. The increasing diameter of the winding roller 49 - while the winding roller 49 is stationary in the Winding position (III) is held by a process the transport device 13 on the lifting table 5 against the direction of web travel (arrow 55), that is in the embodiment shown in Figures 1a to 1d the winding machine to the right, balanced.

Below the one in the winding position (III) Winding roll 49 is one over the entire Width of the winding roll 49 extending, also as The squeeze roller 63, by means of a guide device, not shown relocatable and to the extent of with the pressure drum 35 forming a winding nip Winding roll 49 can be pressed. The squeeze roller 63 is used to introduce Air between the winding layers of the winding roller 49 prevent, for example, when the material web 3 is performed in a free move. The contact pressure, with the squeeze roller 63 to the circumference the winding roll 49 is pressed is adjustable. The squeeze roller 63 can be driven by a drive, for example, a center drive become.

In the following, the function of the winding machine 1 are explained in more detail using a winding process. For reasons of clarity are in the figures 1b to 1d that described with reference to Figure 1a Parts of the winding machine 1, by means of which the pressure drum 35 is publisher-based, not shown. The material web 3 is on the pressure drum 35th guided and on the stationary in the winding position (III) held winding roll 49 wound up (FIG 1a). Before the winding roll 49 its final / target diameter reached, the squeeze roller 63 pressed to the circumference of the winding roller 49. it then the pressure drum 35 becomes vertical down into the lowered, shown in Figure 1b Move position in which the material web 3 in a free train from the pressure drum 35 to Winding roll 49 is guided. Furthermore, the empty drum 45 from that shown in Figure la Waiting position (I) in the direction of the winding position (III), in which the winding roll 49 is still located, method. Before or during the empty drum 45 move in the direction of the winding position (III) the first drive 51 with the empty one Drum 45 coupled and this at running speed the material web 3 accelerates. Before the empty one moving in the direction of arrow 55 Drive over reel 45 to position (II), i.e. above the pressure drum 35 has passed this the almost finished winding roll 49 in the direction of one Finished winding position (IV) shifted so that the Winding position (III) is free and the empty reel 45 held in place by suitable means can be.

The pressure drum 35 is then vertically upwards in the raised position shown in Figure lc shifted in the center of the pressure drum 35 lies in the imaginary plane E. The winding gap between pressure drum 35 and empty drum 45 is by a horizontal relative movement the pressure drum 35, which by a method of Transport device 13 and / or the guide carriage 23 is realized in the direction of Arrow 55 formed. This winding phase is in figure 1c. The of the pressure drum 35 over a peripheral area of the empty reel 45 and this guided in a free train to the winding roll 49 Material web 3 is in the area of the free Train by means of a known, with a Arrow 65 indicated separating device for Example can be formed by an air blowing nozzle separated and their free end on the drum 45 wound up (Figure 1d). The increasing diameter the on the stationary in the winding position (III) held drum 45 -not shown- winding roll is made by a process of the transport device 13 as shown in FIG la described - against the direction of travel of the material web (Arrow 55) balanced to the right and the line force in the winding gap by a process of the guide carriage 23 in the direction of the double arrow 27 controlled, if necessary regulated.

The full winding roll 49 will be reached after Finished winding position (IV), as shown in Figure 1d, from the second drive 53 to a standstill braked. The second drive 53 is then released from the winding roller 49, to the in the winding position (III) guided drum 45 guided, which is driven by the first drive 51 and coupled with it. Then will the first drive 51 detached from the drum 45. There are so briefly both drives 51, 53 with the reel 45 effectively connected. So the drum change completed. As shown in Figure 1d, is used to prepare the subsequent drum change an empty drum 67 in the waiting position (I) introduced.

In the described with reference to Figures 1a to 1d Winding machine 1, the drives 51, 53 alternate, one after the other with a winding roll or with the drum on which the winding roll is wound up, coupled to this apply a defined drive or braking torque. According to a further variant (not shown) it is envisaged that one each the drives 51, 53 during the entire winding process a winding roll or one Drum is assigned. This will be more advantageous Way discontinuities of line force and thus the winding hardness or the winding hardness curve avoided, which may be at one Change the drive as shown in Figures la bis 1d described- can occur. In this embodiment is just one of the two Storage and transport facilities assigned to a drum, which this from the waiting position (I) to leads to the finished winding position (IV). The next The drum is then used by the other of the warehouse and Transport equipment led.

Figure 2 shows that described with reference to Figures 1a to 1d Winding machine 1, in which the reel change according to a further variant is carried out. This is characterized by that the pressure drum 35 from its lowered, in Figure 2 with the solid line position shown only then vertically upwards in their in figure 2 shown with dashed line, raised Position is moved if the towards the empty reel traversing the winding position (III) 45 this already happened and the winding position (III) has reached and held stationary in this becomes. By this measure and by the defined Distance of the winding position (III) to the position (II) it is ensured that after the pressure drum 35 reached their raised position has, the material web 3 the extent of the empty (from the first drive 51) drum 45 initially only tangent or wrapped only weakly. The peripheral area of the empty drum 45, over which the material web 3 is guided, can then defined by a process of the pressure drum 35 in the direction of the in winding position (III) held drum 45 can be enlarged. Advantageous here is that with a relatively simple Control on when placing the material web 3 the circumference of the drum 45, that is, with an enlargement of the wrap angle on the material web acting forces can be kept small. Position II above is preferred a starting position for the pressure drum 35, in who move them vertically by means of the lifting table 5 becomes,

A third variant of the winding process with that described with reference to Figures 1a to 1d Winding machine 1 is used in the following of Figures 3a and 3b explained in more detail. The empty reel 45 is moved from the waiting position (I) shifted the position shown in Figure 3a and held between the starting position (II) the pressure drum 35 and the winding position (III) lies. Then the pressure drum 35 by means of Move the lifting table 5 vertically upwards until it is Center lies in level E. By horizontal Movement of the pressure drum 35 by means of the Transport device 13 and / or the guide carriage 23 in the direction of arrow 55, i.e. in Figure 3a to the left, the winding gap with the empty drum 45 formed. Then the empty one Drum 45 and the pressure drum 35 together in Proceed in the direction of arrow 55 until the empty one Drum 45 has reached the winding position (III).

Now the material web can - as with the figures 1c and 1d described on the empty drum 45 be transferred.

From the description of Figures 1a to 3b results the above-mentioned procedure with the Features of claim 1 without further ado. This is particularly characterized in that the vertical position of the winding gap preferably during the entire winding process in the horizontal Level E lies and that the center of the pressure drum is in level E or above. Further the drum with the wound on it Winding roll at least during the winding process only along a horizontal guideway relocated by the arrangement of the guide rails 31 of the guide 39 is set.

The pressure drum 35 is in the on the basis of the figures 1a to 1d explained winding machine 1 vertically can be moved along a straight line. Of course it is also possible to run this along one increasing gradient to the inclined plane move or the vertical displacement of the pressure drum 35 by pivoting the pressure drum or to realize the lifting table 5. It is important that the pressure drum in vertical Direction is shiftable, so that this the horizontal guideway of the drum and can be driven into it again. Thereby it is ensured that the reel is the pressure drum pass horizontally and into the winding position can be shifted without these together get in touch.

To control the winding machine 1 is that in Figure 1a highly schematically represented control unit 61 provided the motor 19 of the threaded spindle 21 of the lifting device 17 depending on the Speed of the diameter increase of the winding roll 49 controls. The diameter increase of the Winding roll 49 is by means of a measuring device 69 measured. The horizontal position of the transport device 13 therefore preferably changes alone, that means only according to the increase of the winding roll diameter. The size of the Line force in between the pressure drum 35 and the winding nip 49 formed is preferred alone, that is, exclusively through one Movement of the guide carriage holding the pressure drum 35 23 determined, preferably by means of a control device 71 regulated. This includes a measuring device 73 for the line force, a Controller 75, a setpoint generator 77 and one not shown control unit / device. The measuring device 73 is connected via a measuring line 79 to the Controller 75 connects or opens into this. The setpoint generator 77 gives the controller 75 the desired setpoint.

In the event that the measured by the measuring device 73 Value of the line force in the winding gap from that deviates from the setpoint generator 77, the controller 75 gives a signal to the Controller / Equipment. This then changes the pressure in the cylinder 29 of the pressing device 25 such that the measured value of the line force approaches the setpoint. This allows the line force even then on a constant, for example Worth keeping if there is a disturbance in the winding process occurs. For example, a malfunction a not very precise method of the transport device 13 so that the position of the the pressure drum 35 and the winding roller 49 formed Winding gap shifts slightly.

In a further embodiment (not shown) the winding machine 1 is provided that the pressure drum 35 stationary, that is rotatable held directly on the transport device 13 is. By moving the pressure drum horizontally 35 with the help of the transport device 13 the line force in the winding gap is controlled / regulated here and thereby balancing the larger be carried out winding roll diameter. In other words, the line force on you set the desired value, the transport device 13 horizontally against the direction of travel the material web 3, that is to say in FIGS. 1a to 3b move to the right, being influenced the line force is controlled / regulated during the travel process becomes. The fact that in this embodiment dispensed with the guide carriage 23 the structure of the winding machine 1 can be simplified become.

In summary, it should be noted that the fact that the line force in the winding nip throughout Winding process by a horizontal shift the pressure drum adjusted or regulated precise control of the winding hardness from the beginning of the winding process to the end of it is possible, whereby a good winding result is achieved can be.
