The specific embodiment
Fig. 1 has illustrated a kind of back winder of continuous handling, wherein from paper machine or paper justifying equipment the paper in reel W of preceding operation part via on volume nip N advance on the roll R, this paper in reel generally has several meters wide.Utilize the endless flexible load-carrying element 1 of belt for example or silk screen to form and to go up volume nip.This load-carrying element 1 of guiding on two deflector rolls 2 and 3, the motion of member 1 is transformed in the opposite direction at each deflector roll place.Direct of travel along paper in reel, first deflector roll 2 can form " hard nip " with the paper roll that starts in the starting stage of last volume operation, promptly make this load-carrying element 1 contact at the certain position place that this member passes through with paper roll, this position is supported on the surface of this roller by deflector roll 2.Back one deflector roll 3 or first deflector roll 2 can be driven vollers, and promptly nip rolls perhaps can be these two rollers independent actuator all is set.Paper in reel is advancing under the guiding of load-carrying element 1 on the machine reel R, and this paper roll forms around spool 5, and spool 5 can utilize the center driver rotation of himself.This spool 5 can move along machine direction with respect to annular support member 1, and spool is set, and the suitable supporting construction of bearing carrier ring utilization that is positioned at roller tube end that promptly makes spool 5 to rotate supports.About this back winder, also have the memory storage (not shown) of empty reel spool 5, spool enters the switching station that is positioned at first deflector roll, 2 places from here, so that the paper in reel that advances to machine reel R is switched, this moment, this machine reel R was just by around full.The paper roll blocked operation carries out with speed of production, and promptly at high speed is delivered to and is switched on the new spool that becomes to advance to send into switching station around the paper in reel of expiring paper roll.
Machine reel R can be in transfer device 7 shifts along machine direction, and this transfer device supports and is positioned at the bearing carrier ring of roller tube end and actuator that utilization is connected to the back winder framework moves.This transfer device 7 is arranged in along going up on the volume guide rail 6 of the basic horizontal of machine direction extension and moves, and is formed by the support of each end that is positioned at spool, and this stent support is positioned at the bearing at end cover of spool 5.When the increasing diameter of machine reel R adds and paper roll when moving forward, this paper roll and load-carrying element 1 keep uninterrupted contact, this is because the transfer path of transfer device 7 forms an angle along the shift direction opening with the paper in reel bearing part of load-carrying element 1.In Fig. 1, the top of annular support member 1, along oblique downward guiding, and the transfer path of roll R (and spool 5) is a basic horizontal in its sense of motion in the paper in reel bearing part.
Fig. 2 has illustrated the situation in last volume operation initial stage, at this moment, spool 5 and on preliminary, transfer to transfer device 7 around the roll R of its formation winding apparatus 8 on preliminary in the volume, this transfer device 7 is operated as winding apparatus on the secondary.For this reason, this transfer device 7 is along move to the position of going up winding apparatus 8 near preliminary in face of direction shown in the arrow of paper in reel direct of travel.In this stage, paper in reel W advances on the roll R via the part from first deflector roll 2 of load-carrying element 1.
Fig. 3 has illustrated this situation, wherein corresponding to the growth of roll R diameter, transfer device 7 shifts forward along last volume guide rail 6 along the direct of travel of paper in reel, thereby this paper roll always contacts annular support member 1 in its bottom side, make paper in reel between the paper in reel bearing part of this annular support member 1 and paper roll neighboring on move on the neighboring of roll R among the volume nip N.The spool 5 that forms the refill of new paper roll is admitted to the preliminary winding apparatus 8 of going up.Fig. 3 has also illustrated a kind of situation, and this moment, this annular support member 1 shifted forward along machine direction, make the deflector roll 2 of winning be positioned at new spool 5 under.The motion of this first deflector roll 2 and annular support member 1 will be described below in further detail.
Fig. 4 has illustrated a kind of situation, and send new spool 5 into switching station by reducing the preliminary winding apparatus 8 of going up vertically this moment, and it is contacted with the part of advancing on first deflector roll 2 of annular support member 1, so that form so-called hard nip.Before this, by this driving of tentatively going up winding apparatus 8, this new spool 5 has been accelerated to web velocity.In switching station, the plane of the central axial line of connection spool 5 and the central axial line of deflector roll 2 is vertical substantially.Compare with Fig. 3 situation, old machine reel R on secondary in the winding apparatus moves forward corresponding to the growth of reel diameter, and promptly volume nip N is moved along the direct of travel on this annular support member top between roll R and the annular support member.Present paper in reel W process between first deflector roll 2 of new empty reel spool 5 and annular support member, and further advancing along the paper in reel bearing part on the top of this annular support member 1, and in last volume nip N around to the periphery of old roll R.Fig. 4 further illustrated in this stage old roll R how to form with pressure roller 9 to contact, and this pressure roller can pivoted and utilized the actuator of himself to be rotated, and its purpose is to guarantee the density on paper roll top layer.Nip between the shell of load-carrying element 1 and new spool 5, that paper in reel is advanced by wherein utilizes mark N1 to indicate.
Fig. 5 has illustrated a kind of situation, the paper in reel that to deliver to old roll R this moment switches to around new spool 5 advances, promptly, behind the nip N1 between the spool 5 and first deflector roll 2, this paper in reel is followed the surface of new spool 5 and is begun to form new machine reel R around it, in this situation, above-mentioned nip N1 forms in the volume operation on preliminary and rolls up nip.Can comprise suitable air blowing method at this changing method that does not describe in further detail, make web breakage and be directed thus round new spool 5.At paper in reel is to utilize known way to carry out blocked operation under the paper in reel speed of production at full speed.Between transfer period, spool 5 is arranged in the preliminary winding apparatus 8 of going up.
Fig. 5 has illustrated how the terminal of winding apparatus is positioned at second deflector roll 3 (position of nip N) before on the secondary of old roll R.Also can proceed on this secondary the volume operation, make and go up the place, end that is positioned at second deflector roll, 3 tops that volume nip N moves to the downward oblique part of annular support member 1 always.
Fig. 6 has illustrated a kind of situation, broken away from and the contacting and transferred to forward by transfer device 7 and remove the station of annular support member 1 around full second-hand machine roll R this moment, pressure roller 9 moves corresponding to this transfer movement simultaneously, makes it keep continuous contacting with the surface of machine reel R.When the second-hand machine roll R removed from annular support member and on beginning preliminary volume roll out when having certain thickness ply of paper the stage around new spool 5, the peripheral direction of annular support member 1 in face of the direction of feed of paper in reel along spool so shifts in the mode shown in the arrow, make the deflector roll 2 of winning further away from new paper roll, and the periphery surface of this paper roll in the free part that follows this deflector roll 2 closely of load-carrying element 1 against this annular support member, that is, this moment, situation was with shown in Figure 2 identical.In this stage, new spool still is arranged in the preliminary winding apparatus 8 of going up.Therefore last volume nip N1 moves with respect to deflector roll 2 along the direct of travel of load-carrying element 1.
Here the direction of feed of paper in reel refers to the direction that paper in reel enters volume nip between annular support member 1 and the spool 5.Therefore paper in reel W can both can be guided (in the mode shown in Fig. 4 to 6 by first deflector roll 2 on part crooked on the deflector roll 2 in annular support member, wherein paper in reel to enter annular support member be by being positioned at jockey roller 10 guiding before this annular support member), perhaps it also can and be positioned under the ply of paper guiding at spool top at spool 5 and enter nip, promptly, before the volume nip N1, it is at first guided along the paper roll surface on entering.
When around full roll R when back winder removes, transfer device 7 can freely move to position shown in Figure 2 towards the preliminary winding apparatus 8 of going up on guide rail 6, in this position, be arranged in this and tentatively go up the spool 5 of winding apparatus 8 and begin roll R around its formation and be admitted to transfer device 7 and roll up on the secondary so that carry out.Then, according to Fig. 2 to 6 along the top of annular support member 1, the paper in reel bearing part carries out volume operation on the secondary of this new roll R once more.Roll up operating period on this secondary, deflector roll 2 is shifted (from Fig. 2 position to Fig. 3 position) by the direct of travel along paper in reel once more, promptly arrive these deflector roll 2 residing positions when once more new spool being sent into switching station.
Here point out, on whole, roll up operating period, it is continuous contacting with the nip of load-carrying element 1, promptly when from preliminary volume when the secondary volume switches, contact with the nip of this annular support member when being continuous maintenances when tentatively upward winding apparatus 8 is sent into transfer device 7 spool 5.This transfer device 7 can begin just onwards to shift spool 5 and paper roll from this fixed position, switching instant and whole preliminary on during the volume, tentatively go up winding apparatus 8 and all spool 5 remained on this fixed position and locate.When spool 5 is sent into transfer device 7 from tentatively going up winding apparatus 8, can be in known manner, the moment of torsion that will be used for spinning reel 5 is supplied with the actuator that switches to transfer device 7 from the preliminary actuator of going up winding apparatus 8.Roll up operating period on secondary, the actuator of transfer device 7 moves with this transfer device with the required speed of speed of production and spinning reel 5 and around the roll R of this spool, after cutting off paper in reel, reduces speed now around full paper roll.
Shift first deflector roll 2 in face of the direction of feed of paper in reel W and realized favourable effect, that is, for example 1 of the annular support member of belt or silk screen against, the position of the periphery that begins the new paper roll that forms around spool 5 can move to the free part of following this deflector roll of annular support member 1 from deflector roll 2.In fact this relatively moving can be realized by shifting spool 5 forward along the throughput direction of strap lug in the winding apparatus on preliminary.But the shortcoming of this situation is, on preliminary in the volume, need roll up on it this because paper in reel W and make the motion channeling conduct of quality continually varying spool 5.When utilizing the method according to this invention when operation, the central axial line of this spool 5 is in this transition phase of last volume nip and even roll up operating period on preliminary and can remain on fixing position whole.And this can make at least that should tentatively go up winding apparatus 8 is maintained fixed, being that it can only move according to a basic vertical transfer path, is not must shift spool 5 for the direction along annular support member and tentatively go up the possibility that winding apparatus provides horizontal motion for this.
Advantageously, this process is such, i.e. volume in the stage on beginning preliminary, after switching, promptly originally reel ply of paper begins to go up volume against hard nip N1 around the paper roll of spool 5 bottom, and this spool 5 remains in the switching station simultaneously, and subsequently by with first deflector roll 2 with respect to spool 5 shift begin to enter second tentatively on the volume stage, after this, the soft nip N1 of paper roll base abuts goes up volume.
By shift this deflector roll 2 along machine direction, can determine suitable reference position, volume stage deflector roll is positioned at this position in switching and first tentatively.When switching paper in reel and paper roll and begin to increase around new spool, corresponding to the increase of paper roll, deflector roll 2 moves down along vertical direction, and by this motion, also first preliminary on volume regulated the linear load of volume nip in the stage.
Fig. 1 has simply illustrated the motion possibility of first deflector roll 2 and second deflector roll 3.Advantageously this first deflector roll 2 can can move along horizontal direction again along vertical direction in the direction of rotation axis perpendicular to it, make that the transfer movement in these directions is separate, wherein can utilize this first deflector roll 2 to determine on preliminary, to roll up the position of rolling up nip on operating period.Therefore, this first deflector roll 2 can with the corresponding to perpendicular of the direct of travel of paper in reel with certain size scope in be positioned the position accurately selected, and can be by the desirable transfer of transfer path realization from the primary importance to the second place.Also there is same motion possibility in second deflector roll 3.In practice, the situation that two deflector rolls all are moved can realize by deflector roll being rotatably connected to first element, and it can be moved along a direction in above-mentioned perpendicular linearly, and this element is set to and can move linearly along the direction perpendicular to this first direction in same perpendicular again.Such element is positioned at the both sides of deflector roll on the edge of back winder.
In the embodiment according to Fig. 2 to 7, full annular load-carrying element 1 should be corresponding to the motion of first deflector roll 2 and is moved, and promptly second deflector roll 3 should be followed the motion of this first deflector roll 2, makes it possible to keep the ideal position of this annular support member.This can realize like this that body interconnects even the rotation axis utilization of first deflector roll 2 and second deflector roll 3 is rigidly connected, and with dashed lines has simply illustrated this connector in Fig. 1.In practice, can further realize this motion, make each deflector roll be installed to movably along short transverse in the support of himself, this support can shift along machine direction in the back winder framework again.Therefore, for example, the support by moving first deflector roll 2 on one's own initiative and by regulating the height and position of deflector roll 2 in support on one's own initiative, deflector roll can be always gone up winding apparatus 8 and spool wherein 5 be positioned in the correct position with respect to preliminary.Second deflector roll 3 is followed the motion of first deflector roll, makes annular support member angle with respect to the horizontal plane change with ideal style or keeps constant.In practice, the motion of second deflector roll 3 should only guide along a direction on one's own initiative, and because this body that is rigidly connected, deflector roll is with in the direction that automatically himself will be positioned at perpendicular to this direction.For example, when utilizing effective actuator to shift the support of first deflector roll 2, and when the effective actuator that utilizes these supports is regulated the height and position of deflector roll 2 in support, in the support of second deflector roll 3, only need on one's own initiative highly regulating, and support can automatically be followed moving of first deflector roll 2 along machine direction by this body that is rigidly connected.
For example can utilize on the connector that is movably connected to deflector roll and with annular support member 1 contacted jockey pulley be implemented in preliminary go up during the volume and particularly on the secondary during the volume as the tension force of this load-carrying element 1 of one of them controlled variable.
Second kind of possibility that the motion of this annular support member is set is to be provided with movably deflector roll 2 and 3, make that they are not that utilization can determine the body that is rigidly connected of the distance between their center-point to be connected, but they can separate fully moving in the restriction that this annular support member sets.For the motion possibility of two deflector rolls, can be identical with it, for example they can move along short transverse and machine direction, but pass through their mutual motion, the present also tension force of this load-carrying element 1 of scalable.
As finding out by accompanying drawing, tentatively to go up winding apparatus and can in vertical direction, move along the vertical guiding device in the back winder framework, i.e. this motion is linear.The lock pawl that the bearing carrier ring of new spool 5 can bonded assembly be tentatively gone up winding apparatus is orientated the direction that paper roll will shift, the i.e. shift direction of transfer device 7 from this framework during secondary is rolled up.Can be by winding apparatus on reducing tentatively and by first deflector roll 2 and annular support member are remained on the position of shifting before it, perhaps winding apparatus 8 is held in place and remain between this load-carrying element 1 and the spool 5 next closed nip N1 between new spool 5 and load-carrying element 1 until paper in reel by promoting first deflector roll 2 by will tentatively going up.
Fig. 7-11 has illustrated a kind of back winder, and wherein each stage and above-mentioned each stage are basic identical.But except first deflector roll 2 and second deflector roll 3, the 3rd deflector roll that also has in annular support member 1 inboard is other deflector roll 11, and this deflector roll is positioned at the front of first deflector roll 2 along the paper in reel direct of travel.At first deflector roll, 2 places, the direct of travel of annular support member does not change over opposite direction, but this load-carrying element 1 is transformed into part along oblique downward guiding along the oblique upwards part of guiding, goes up volume nip N simultaneously and roll up on secondary and shift in operating.Between the other deflector roll 11 and first deflector roll 2 along on the part of oblique upwards guiding, this load-carrying element 1 is towards scrolling up nip N1 delivery roller paper.This other deflector roll can be used for regulating the tension force of load-carrying element.And at the arranged outside and the load-carrying element 1 contacted roller 12 of annular support member, it can be used as guide reel, by its motion (arrow) of an end can be in horizontal direction positioning supporting components 1.
The advantage of embodiment in Fig. 7-11 is, when the volume stage on preliminary need change deflector roll 2 and on during the mutual alignment of volume nip N1, only need first deflector roll 2 in the deflector roll in the shift ring, and other deflector roll can all remain on identical position in all stages.
The plane flexible strut member 1 that utilizes two or more deflector rolls to form closed loop is preferably breathed freely, for example silk screen.But other ventilative load-carrying element also is positioned at the scope of the invention, for example has the belt of closure surfaces.This load-carrying element has same structure in the horizontal direction of machine, promptly it is corresponding to the width of the paper in reel of going up volume.But the scope of the invention also comprises this thought, and promptly this closed loop is formed with parallel relation closed loop of advancing adjacent one another are by a plurality of, and identical shown in the global geometric shape in the lateral plan and Fig. 2 to 11.Like this, the tension force of these closed loops for example can be according to being regulated independently by the known principle of EP-860391.
The preliminary winding apparatus 8 of going up preferably can move straight up and down, and in this case, at the upper position place, this device obtains new spool 5 from memory storage, and in lower position, forms and switch and the preliminary volume station of going up.But switch and preliminary on the volume stage keep this new spool should be preliminary on winding apparatus can be completely fixed in its position.At this moment, utilize special transfer component for example jacking system new spool is sent into the preliminary winding apparatus of going up from the top.Therefore, should be by moving first deflector roll 2 with volume nip N1 on the closure.
