Web afterbody connects the specific stage that usually occurs in.In other words be not, to connect at a dass web afterbody by whole machine.Under normal circumstances, web afterbody and whole fiber web are at the end in each stage, and the end of all drying sections as shown in Figure 1 50, temporarily moves towards pulper 44.If web afterbody should rupture before rewinding machine, can avoid like this repeating web afterbody in the whole length of fiber web machine and connect the needs of operation.
As shown in Figure 1, in drying section 50, the fabric loop (fabric loop) 28 that is subject to guiding machine part 12 ' supporting is arranged between machine part 12.In this case, fabric loop refers to the wet end fabric that is arranged to ring-type, and guiding machine part 12 ' refer to deflector roll.When the wet end fabric of fabric loop 28 with when playing drying cylinder that machine part 12 acts on and contacting with each other, between them, form holding point 14.This holding point refers to that during one or more machine parts rotations, described at least one contact point is carrying fiber web and web afterbody at least one contact point between two machine parts between machine part and fabric loop or alternatively.That is to say, in the time of contact point between machine part and fabric loop or between two machine parts of fiber web or web afterbody, just form the holding point of carrying fiber web and web afterbody towards the direction of rotation of machine part.
Arrangement according to the invention comprises three essential parts.Part I is by forming for the building mortion 18 that forms web afterbody 10 from fiber web.Part II is the cutter sweep 13 for cutting web afterbody 10, and Part III to be web afterbody connect equipment 16 discharges web afterbody 10 for the surface of the machine part 12 from rotation, and the web afterbody 10 of cutting is like this forwarded.Building mortion 18 can be made up of for example tooth shape cutting machine or similar device, for web afterbody is separated along the direct of travel of fiber web and the fiber web of whole width.The width of web afterbody can be for example 200mm.In embodiment as shown in Figure 1-Figure 3, fiber web is plate web, and in this case, preferably building mortion is made up of tooth shape cutting machine, because plate needs higher mechanical strength in cutting process.Building mortion 18 be positioned at the holding point 14 that is in before pulper 44 ' before; That is to say, before the machine part 12 along the direct of travel of fiber web before being positioned at pulper 44.More precisely, building mortion preferably web afterbody connect immediate holding point 14 above of equipment 16 ' and the second immediate holding point 14 " between.In other words, web afterbody also can form in the region of descending web.Preferably, in embodiment as depicted in the figures, web afterbody forms in the fiber web moving up.
Cutter sweep 13 is a kind of devices for cutting web afterbody 10, according to the present invention, this device be positioned at the holding point 14 that is in before pulper 44 ' before; , along the direct of travel of fiber web the machine part 12 before being positioned at pulper 44 before.Or rather, cutter sweep 13 is arranged in so-called open draw part, makes the cutting of web afterbody 10 occur in the not supported part 19 of the web afterbody 10 between two holding points 14.Preferably cutting occurs in the traction process that web afterbody advances to higher machine part 12 from lower machine part 12, in process upwards.Preferably, cutter sweep 13 is near of pulper 44 machine part 12 above, between the machine part 12 before pulper 44 and the immediate machine part 12 before above-mentioned machine part 12.According to shown in Fig. 1 to Fig. 3 because web afterbody is to form by building mortion 18, therefore cutter sweep 13 always along the direct of travel of fiber web be positioned at building mortion 18 after.Preferably, building mortion 18 and cutter sweep 13 are all in the identical not supported open draw part 19 of the fiber web between two holding points 14.In this article, word " not supported " means in this open draw part between holding point, and fiber web and web afterbody thereof are not subject to for example roller, fabric or the similarly supporting of supporting member.The tractive that only the advancing of web afterbody and fiber web produces by the traction point being positioned at along direct of travel thereafter and directed.After the cutting of web afterbody, web afterbody is temporary transient only directed by its linear momentum.The cutting of web afterbody occurs in web afterbody and transmits in district, and web afterbody is directly towards the holding point operation being positioned at along direct of travel thereafter herein.
Web afterbody connects equipment 16 and can be made up of the equipment of setting associated with machine part 12, and this equipment discharges fiber web for the surface from machine part 12, and is forwarded holding point 14 subsequently.Web afterbody connects equipment 16 and can comprise: independent releasing device 46, and it can be for example shown in Fig. 2 or Fig. 3, to pick up blowpipe 36; One blade construction or the similarly solution of prior art, it can discharge fiber web in the surface from rotary machine part 12 in the case of advancing in the end of the web afterbody 10 that do not slow down, thereby prevents to relax.Web afterbody connects the conveyer 26 that equipment 16 can also comprise web afterbody 10, this conveyer can be for example by the vacuum belt conveyer shown in Fig. 2, blow plate or a simple plate forms.Conveyer 26 is for transmitting the holding point 14 of the web afterbody discharging from machine part 12 10 further facing backwards, and this holding point can be for example nip or the rewinding machine between felt wrapped roll.
In order to carry out the method according to this invention, web afterbody 10 is to utilize building mortion 18 to be formed by fiber web.In the time that needs continue to connect web afterbody to distant place, utilization is in web afterbody and connects equipment 16 holding point 14 before cutter sweep 13 above, cutting web afterbody 10 in the not supported part 19 at web afterbody 10 between two holding points 14.Web afterbody 10 discharges from the surface of machine part 12 and utilizes web afterbody to connect equipment 16 and forwards.In other words,, when needs continue to connect web afterbody forward time from pulper 44, the building mortion 18 being comprised by this layout forms web afterbody in entering the fiber web of pulper 44 travelling through the walking of going forward side by side of holding point 14 and scraper 40.In the time that web afterbody 10 extends to pulper 44, cutter sweep 13 cutting web afterbodys 10, and make thus the web afterbody 11 before holding point enter pulper 44.Be positioned at web afterbody 10 after cut point by its linear momentum not supported advance to holding point 14, the further tractive web afterbody 10 of this holding point 14 arrives web afterbody and connects equipment 16.
In this application, preferably, scraper 40 is combined predetermined web and the web afterbody that carries out break process of guiding and is gone to pulper with lower pull tool (not shown).Preferably, lower pull tool is made up of drop-down blowning installation (pull-down blow).When web afterbody leaves 14 ' time of holding point, this pulldown function can produce gap on cutting position.
The cutter sweep using in arrangement according to the invention is preferably the water cutting machine for cutting web afterbody.Water cutting machine can by across web afterbody laterally mobile water jet carry out cutting web afterbody.Then,, in the time that web afterbody 10 moves forward, in web afterbody 10, the wedge shape forming as shown in Fig. 4 a is cut sth. askew to 56.Can be that final when cut when web afterbody, the end of cutting sth. askew just arrives holding point, to can keep the tractive of nearly continuity in web afterbody by the arrangement of time of this cutting operation at this.Can adopt in the method according to the invention water cutting or blade cuts.
According to an embodiment, cutter sweep has cutting sequence, and this cutting sequence control water jet makes water jet along horizontal initial cut stage fast moving in the time starting from the first edge of web afterbody, and more slowly moves in the time approaching the second edge.Therefore, 56 will form an obtuse wedge 58 by cutting sth. askew of web afterbody 10, as shown in Figure 4 b.After through obtuse point 58, the current of injection will move more lentamente, form thus long leg and divide 60.Obtuse shape can more effectively be resisted the power of pointing to web afterbody in holding point.
The advantage of arrangement according to the invention and method is: in the time forwarding, can prevent that web afterbody is in relaxed state.In prior art scheme, after web afterbody cutting occurs in holding point, or rather, only occur in and utilize web afterbody to connect equipment to make after web afterbody leaves machine part surface.Based on the reason of space requirement, web afterbody connects equipment and is therefore usually located at the below of the axle of machine part, thereby it is even annular to make web afterbody can after it is cut, continue to form racing towards forwarding before holding point is subsequently advanced.Then can cause easily laxly, upset web afterbody is connected process by this.In arrangement according to the invention, cutting completed before holding point, in this case, the web afterbody that leaves holding point can be after holding point discharges from machine part surface as quickly as possible, and is directly guided and be tensioned to that web afterbody connects equipment and towards follow-up holding point.Web afterbody connect equipment can be positioned at web afterbody and connect machine part before equipment substantially in same level.The statement of " substantially in same level " means that this web afterbody connects in the vertical spacing of equipment between highest face temperature and the minimum surface of machine part.Therefore can be according to fiber web the course in operating process provide the course of the standard of being close to for web afterbody.
Fig. 2 shows the another kind of embodiment of arrangement according to the invention.In figure, clearly describe and how to have made web afterbody 10 can be after holding point 14 discharge from the surface of machine part 12 immediately, thereby can be almost directly and by being included in web afterbody have connected conveyer 26 (in this case vacuum belt conveyer) in equipment 16 towards guiding forward web afterbody 10 in this unshowned follow-up holding point.In should embodiment, the releasing device 46 that web afterbody connects equipment 16 comprises and can pivotable pick up blowpipe and blow plate 24; Pick up blowpipe 36 and by means of blowing, web afterbody 10 is discharged from the surface of rotary machine part 12, and by blowing plate 24, web afterbody 10 is forwarded.Also can use conveyer to replace and blow plate.
Fig. 3 shows the third embodiment of arrangement according to the invention, is included in the blowpipe 36 that picks up that web afterbody connects in equipment 16 discharges web afterbody 10 from machine part in this use.The position of in this embodiment, picking up blowpipe 36 is lower than embodiment as shown in Figure 2.But, discharge the position that web afterbody 10 occurs in higher than existing technical scheme, compared with prior art scheme, this embodiment allows web afterbody 10 more directly to advance to follow-up holding point 14.In the present embodiment, follow-up holding point 14 is made up of carrying rope sheave 38, and carrying rope sheave 38 forwards web afterbody 10 from this holding point.Carrying rope system can comprise that web afterbody connects rope 37 and rope sheave 39, and rope sheave 39 can move near of machine part 12 duration that web afterbody connects process, and in course of normal operation, moves to side.
Fig. 1-Fig. 3 shows the application that this layout is associated with the drying section being applied in two fabric operational systems.In this case, machine part 12 is rollers, and holding point 14 forms between roller and fabric loop.Fiber web does not move into place in the open draw part between holding point 14 not supportedly.There are two fabric loops at this: one is positioned at top, and another is positioned at bottom.If drying section is implemented as single fabric operational system, can one space be set on the cutter sweep between machine part by the ring of for example wet end formation of fabrics, in this ring, fabric is for example advanced via two roller (not shown).This design can be similar to the technical scheme being generally used for according to the fabric loop of prior art.Thus between fabric and fiber web for cutter sweep provides a space.Arrangement according to the invention is applicable to be applied in the drying section in single fabric operational system or two fabric operational system.
Compare with common practice with prior art, it is unexpected that part be can be before holding point, in the interval between holding point, (do not supported) cutting web afterbody in this web, in this case, web afterbody can keep without traction in part distance.Because web afterbody in web afterbody connects process is also to move with significant speed, therefore there is certain linear momentum, this linear momentum can also still make web afterbody keep forward even without provisional traction after cutting.Therefore the web afterbody, being supported will continue towards moving with direction identical before cutter sweep.
The basic element of character using in arrangement according to the invention, building mortion, cutter sweep and web afterbody connect equipment, can be similar to the equipment of prior art, can make thus this layout become simple and save cost.
Preferably, this layout and method are applicable in plate production, because plate has very poor folding property based on its rigidity, therefore in the time using prior art, are very easy to keep lax in the cutting of web afterbody and web afterbody deenergized period.In this article, plate refers to that basic weight exceedes 125g/m
2fiber web.This layout is also applicable to paper and produces.Arrangement according to the invention preferably adopts the method according to this invention.
