Abstract
Rewinder and Method for threading a material web into a rewinder, in which the start of the material web is drawn off a supply roll at full width by an auxiliary device in order to improve automation possibilities. Further, provision is made for the material web to be fed to a winding position at full width and for the auxiliary device to be released from the material web in the region of the winding position.
Description
Technical field
The present invention relates to a kind of band (material web) be worn the method for leading in the rewinding machine, wherein band is pulled out from the supply roll coil of strip with the initiating terminal of full duration state by auxiliary device.In addition, the invention still further relates to a kind of rewinding machine, it has the station of expansion and winder station, launch station and have the position that at least one is used to supply the roll coil of strip, winder station has at least one winding position and auxiliary device, auxiliary device launch station zone clamping from the band of the supply roll coil of strip with the full duration state.
Background technology
Such method and rewinding machine are disclosed in EP0820946B1.For the ease of the coiling band, band is directed on the cutter sweep after pulling out on the supply roll coil of strip, and this cutter sweep cuts out tip (point) from band.For this purpose, rewinding machine has at least one cutter, when band can laterally move with respect to the band moving direction through out-of-date this cutter.In this mode, by use this cutter can with angled ground of band moving direction cutting of web.Because this tip can easier operation band.But also by some shortcomings.At first loss the band of scheduled volume.This part band no longer has overall with after cutting out the tip.Partly arrive winding position because band must continue to move forward up to its overall with after arriving winding position, so operating winding needs the more relatively time.Usually the speed that moves forward is less than winding speed.Therefore consumed the relative plenty of time.Also need operator or sensor to determine when to arrive band overall with part.This monitoring can cause the mistake that adds in addition, makes the automation mechanized operation difficulty that becomes.
Summary of the invention
The purpose of this invention is to provide a kind of automatic guidance.
Purpose of the present invention realizes by following manner, promptly at the initial period of said method, band is directed to winding position with the full duration state, and in the winding position zone band and auxiliary device is separated.
By this structure, all saved required intermediate steps, promptly band is being worn the cutting tip step of carrying out before leading in the rewinding machine, and the step at the cut-out tip after arriving winding position.By contrast, the band that this structure not only can the clamping overall with can also make band pass whole rewinding machine with unmodified form (being full duration), up to arriving winding position.Here only need band is separated with auxiliary device, and begin to carry out operating winding.Therefore neither can or not pass through winding position and elapsed time by a large amount of relatively band of loss in order to make the tip yet.Though also loss band slightly here, this loss only is limited to a part, promptly in order to be firmly held in a necessary part on the auxiliary device.But auxiliary device automatic guidance.Because band always is in the overall with state, so can save the sensor of judging width.In addition, operator's monitoring becomes easier.
Preferably band is through slitter, this slitter at auxiliary device by being in open mode before.Formed in the process of reel by the former roll coil of strip (parent reel) or the large-scale roll coil of strip (jumbo reel), band is cut into the required width of user usually.Slitter is required for this purpose.Therefore can obtain a large amount of reels by the former roll coil of strip.Slitter all comprises two row's cutters in many cases, and it shears band from both sides.In order to make band process under the control of auxiliary device, this two rows cutter must be removed enough distances so that the auxiliary device process.Yet this is easy to realize.
Preferably slitter is closed through later at auxiliary device, and produces at least one vertical cutting part before auxiliary device arrives winding position in band.This is to save time and the another kind of measure of material.Usually wish beginning winding part band, promptly the strip coil that will be separated by slitter when winding position is separated from one another when the part band is on a plurality of reels.If through cutting of web immediately later, then can make " shearing " zone become very short at auxiliary device.For example, if slitter is closed immediately after auxiliary device passes through, then can keep the not share zone of 50cm to 1m.In order to begin to carry out actual operating winding, only this zone is sent to outside the spool positions.
Preferably auxiliary device further transmits band after arriving winding position, arrives winding position up to vertical cutting part.Thereby single reel no longer is connected to each other together.
In this case, preferably band is wound on the auxiliary device in the winding position zone, arrives winding position up to vertical cutting part.Therefore after arriving winding position, no longer need to be moved further auxiliary device vertical cutting part is sent to winding position.Auxiliary device for rotation or its part band of reeling simply.
Preferably, band is firmly held in the winding position zone, and band cuts off between winding position and auxiliary device, and auxiliary device moves to the processing position.Handling the position, the cut-off parts of band (particularly not cutting part) falls (for example launching) and delivers to the pulper from auxiliary device.Auxiliary device continues the initiating terminal of the next band of clamping then.
If auxiliary device is from the take-off location to the winding position and to return be that what to move along loop also is favourable.In this structure, for example can guide auxiliary device from the supply roll coil of strip to the process of winding position, passing slitter, and in the process of returning (promptly from winding position to the supply roll coil of strip) can walk around slitter.Just can begin to reel in case result's auxiliary device arrives winding position, comprise rip cutting.Auxiliary device do not transmitted can hinder operating winding.
In the rewinding machine of the above-mentioned type, can be by making auxiliary device move to winder station, arriving winding position and realize the object of the invention from launching station.
Therefore can be by the initiating terminal of auxiliary device with full duration state clamping band.If the down-stream guiding auxiliary device according to band passes rewinding machine, then auxiliary device can draw with the band of full duration state in its back.Therefore only need guarantee whether auxiliary device arrives winding position, after cutting off band from auxiliary device, band can be wound on the ready core in winding position place.
Preferably launching between station and the winder station slitter to be set, slitter has cut state and transition condition (passage state), and it vertically cuts the band of process, the removable slitter that passes through of auxiliary device when transition condition when cut state.Usually slitter has the two row's cutters that are arranged in the band two sides, and band is divided into a plurality of strip sections (part web), two cutters always interact vertically to cut.Therefore in cut state, there is not space even stacked on top of each other between the cutter.If therefore auxiliary device is through slitter, auxiliary device needs some spaces.Cutter is separated.So entered transition condition.The result of conversion can make band pass through whole rewinding machine with the full duration state between two states, especially passes through slitter.
In this case, preferably slitter has two cross members (crossmember), and one of them can move with respect to another.By mobile cross member, can create in simple mode is that guiding is connected with the auxiliary device of band by the required space of slitter.Compare with mobile cutter on cross member, it is simpler usually to realize moving at least one cross member.
Preferably auxiliary device is directed on two mobile routes, and these two mobile routes are laterally arranged with respect to the band moving direction, and each interval one preset distance.For example mobile route can be made of track or guide rail.Auxiliary device is supported on the both sides, means that this auxiliary device can obtain guiding very quietly.By such support, band can be guided through rewinding machine under the situation that folding line can not take place or tear.Distance between two mobile routes also can guarantee to tilt.
In this case, particularly preferably, with the outside of these mobile route lateral arrangement at band.Therefore these mobile routes can not hinder the residue component part (remainingconstituent parts) of rewinding machine when operation.Especially, although there is mobile route, need not adopt any method to come closed slitter in the slitter zone yet.These mobile routes laterally are positioned at the outside of slitter.
The mobile route of auxiliary device is loop preferably.Therefore auxiliary device can move to winder station from launching station in the first of mobile route, is moved back into the expansion station at second portion from winder station.Therefore auxiliary device is guided the operation that can not hinder rewinding machine.
Selectively or additionally, make mobile route be used for two-way moving.In other words, if desired, auxiliary device can be when the threading material be got back to the expansion station from winder station on the same section of the mobile route of process.In this case, because slitter must stay open state before auxiliary device is returned, so have the shortcoming that has postponed slitter cut-in time.But when the restricted quarter, can accept this shortcoming.
Preferably, transmitting device (transport device) is directed along at least one mobile route.Therefore do not need auxiliary device itself to have the actuating device that therewith moves.On the contrary static actuating device can be set, it acts on the transmitting device.This transmitting device can be made of for example chain, band or hawser, and draws auxiliary device along mobile route.
It also is favourable that the cross-cutter that band between auxiliary device and the winding position is worked is arranged in the winding position zone.Under the effect of cross-cutter, band can be cut off between winding position and auxiliary device.Can simplify the threading material like this.Do not need at first to discharge band from auxiliary device.Therefore not absolute demand carefully can damage band when the initiating terminal of auxiliary device clamping band initiating terminal.The sub-fraction of loss band is an acceptable, as long as this part is required when being auxiliary device clamping band.
It also is favourable that the expansion station has ready position, and thereunder is furnished with the pulper mouth, and auxiliary device is removable through the zone between ready position and the pulper mouth.Launch station and all have expanded position usually, and the former upon deployment roll coil of strip is positioned at wherein.For two former roll coil of strips can successfully be changed, launching that another space, i.e. ready position at least are set on the station.Prepare that in this ready position the new former roll coil of strip is arranged, that is to say that the skin that is easy to damage launches to produce straight band front edge, its moving direction with respect to band becomes about 90 °.This operation also is called as " stretching (squaring) ".Damage owing to can produce some in this operating process, promptly the skin of the former roll coil of strip damages, and it is directly dropped into the pulper mouth is favourable.Therefore the initiating terminal of the band that downward near vertical is hung is directed to the pulper mouth from ready position.In this case, can make relatively easily clamping band of auxiliary device.Only need from the band back, promptly from the back of the band of moving direction, auxiliary device moves up.If auxiliary device has clamped band, can band be sent to winding position by simply moving forward auxiliary device subsequently.
Preferably cross-cutter is arranged in this zone.Be convenient to produce neat band initiating terminal like this.If auxiliary device has clamped band, the band of cross-cutter action and cut-out auxiliary device downside.Cut-off parts drops in the pulper mouth.Auxiliary device can controlled the initiating terminal of band securely then.
Preferably cross-cutter has cut zone, and it can move on the moving direction of band.In some cases, the former roll coil of strip or the large-scale roll coil of strip are not that identical diameter is always arranged.If the former roll coil of strip always is positioned at identical ready position, then the initiating terminal of band also is suspended on the diverse location on the moving direction downwards.This is no problem usually for auxiliary device, because it can at any time move along moving direction, therefore can adapt to little position difference difference.If slitter similarly can move, then it similarly can adapt to this little position difference.
Preferably auxiliary device has sucking hole and/or holding device.Be used for controlling securely the initiating terminal of band.Sucking hole is being controlled band securely by vacuum.Certainly in this case, need guarantee that air can discharge from auxiliary device, or at any time from sucking hole, discharge.Under the situation of using holding device, but only need to guarantee the initiating terminal of these holding device clamping bands and can control band securely.Two kinds of anchor fittings are all remote controlled, i.e. operation from the outside.
In this case, preferably, the actuation gear that auxiliary device is worked is set in expansion station zone.Thereby can behind the clamping band, actuate auxiliary device at once.If auxiliary device is being controlled band securely by sucking hole, then for example under the effect of actuation gear, in auxiliary device, produce vacuum.If controlling band securely by holding device, then actuation gear can be actuated holding device.Usually, actuation gear only works just enough in the initial secured stage of auxiliary device.Therefore can make actuation gear keep static, but also can move a little in this case to be adapted to the diameter difference of the former roll coil of strip.But do not need to make actuation gear to move to winder station, and then retract from launching station.This makes guiding become easy.
Preferably actuation gear is a rotating driving device, and it can be worked with auxiliary device and be connected.Therefore rotating driving device makes the auxiliary device rotation, thereby makes auxiliary device roll the initiating terminal of band.In case obtain the winding layer of scheduled volume, as long as have predetermined tensile force, band just is firmly held on the auxiliary device.For example can close the vacuum at sucking hole place then or reduce the power that holding device applies.Being operatively connected by engageable power-transfer clutch between rotating driving device and the auxiliary device realizes that rotating driving device just can not participate in whole the moving of auxiliary device like this.
The rotating driving device of the auxiliary connecting device of can working preferably is arranged in winding position.After arriving winding position, this rotating driving device also can for example pass through the power-transfer clutch auxiliary connecting device.Rotating driving device can make auxiliary device further rotate, the band part of reeling and not cut by slitter.Can under the situation that is not moved further auxiliary device, move band to winding position like this, and have only the cutting part of band to be positioned at winding position, and the formation reel separately of reeling.
Preferably launching between station and the slitter docking station to be set.Such docking station for example can produce known " abutment joint ", as described in DE19923097A1.This docking station can save and upgrade insertion process or after changing the former roll coil of strip band worn and lead in the rewinding machine.The initiating terminal of the new former roll coil of strip can simply be connected to an end that launches the former roll coil of strip.
Preferably auxiliary device moves in the underground space, launches station and winder station and is arranged on the ground.In other words, moving at " subterranean room " of auxiliary device carried out, and expansion station and winder station are arranged on " ground ".This layout has increased safety.Be positioned at that the operator who launches station and winder station zone contacts auxiliary device and the possibility that comes to harm is relatively low.
Description of drawings
Below in conjunction with accompanying drawing and preferred embodiment explanation the present invention, wherein:
Fig. 1 is the scheme drawing of first embodiment of rewinding machine,
Fig. 2 is the scheme drawing of second embodiment of rewinding machine,
Fig. 3 is the detailed view at X place among Fig. 2, and
Fig. 4 is the detailed view at Z place among Fig. 2.
The specific embodiment
Fig. 1 is the scheme drawing with the rewinding machine 1 that launches station 2 and winder station 3.Slitter 4 is arranged in and launches between station 2 and the winder station 3.
Has expanded position 5 at the expansion station.Have the bearing 6 of expansion at expanded position 5, wherein spool 7 is installed in rotation on it.The former roll coil of strip 8 is wound on the spool 7, also can find out its part from Fig. 1.Band 9 is pulled out from the former roll coil of strip 8, and the former roll coil of strip 8 also can be described as " the large-scale roll coil of strip ".Band 9 is cut into a plurality of strip sections at slitter 4 places, and is wound into a plurality of reels 10 at winder station 3 and since these reels 10 on the direction vertical with plane, accompanying drawing place one by one, so in Fig. 1, can only see a reel.
Launch bearing 6 and be suitable for relative high-speed operation.For example, can 2000 speed that arrive 3000m/min extract band 9 out.Certainly, can arrange identical expansion bearing 6 at the opposite side of spool 7.
Reel 10 is bearing on two bearing rollers 11,12, and wherein at least one is a driven voller.Loaded roll 13 can be set with the control operating winding." the two bearing roller rewinding machine " of backing roll rewinding machine shown in substituting also can be set, and wherein the center of reel 10 keeps and is bearing on backing roll or the touch roll.
Launch station 2 and also have ready position 14, have another spool 15 thereon in advance with new former roll coil of strip 16.This ready position has preparation bearing 17, and similarly it allows spool 15 to rotate, but because required here rotative speed is slower, so its structure is fairly simple.Preparation bearing 17 and launch bearing 6 and be connected to each other by running track 18 and be in the same place, when needs were changed spool, spool 15 can 5 rollings from ready position 14 towards expanded position on the running track.
Prepare to have the former roll coil of strip 16 in ready position 14.In order to prepare, launch and arrange which floor band usually.This operation also is called as " stretching ".For the ease of handling band 9 parts, pulper mouth 19, particularly by gravity are set below ready position 14 band 9 is hung contact pulper mouth 19 downwards.Because the radius of the former roll coil of strip 16 is always not identical, so the position of the band 9 that hangs can change a little downwards.Can receive the band that falls but pulper mouth 19 is very big.If desired, also funnel 20 can be set in addition.
Sometimes need band 9 is directed to winder station 3 from launching station 2.In this process, band 9 also must be through slitter 4.This process also is called as " threading material ".
In order to realize the threading material, rewinding machine 1 has auxiliary device 21, and the diverse location in Fig. 1 shows this auxiliary device.For the sake of clarity, (a, b c) represent auxiliary device 21 by lowercase at diverse location.
Auxiliary device 21 is directed along the mobile route shown in the long and two-short dash line 22.Mobile route is made of the track or the guide rail that are arranged in band 9 both sides (and in width outside).Can also be along mobile route 22 guiding chain, band or hawsers, these devices drive by common type of drive, no longer specify here, thereby on the direction vertical with band 9 moving directions auxiliary device 21 are directed to winder station 3 from launching station 2.
(left side shown in Figure 1) rises to because gravity and the band 9 that hangs downward vertically auxiliary device 21 from the left side, and is fixed on the band.For example, auxiliary device 21 can have sucking hole, does not here understand specifically.If produce vacuum at the sucking hole place, then auxiliary device 21 just can controlled band 9 securely.Also available holding device replaces sucking hole controlling band 9 securely.At last, auxiliary device 21 is rotated around axle (perpendicular to the plane at accompanying drawing place), it can be by rotating the band 9 of reeling in several weeks and hanging downwards like this.As long as keep enough tensile forces in band 9, band 9 just can be firmly held on the auxiliary device 21.In order to realize reeling, auxiliary device 21 can link to each other with static rotating driving device, does not understand specifically here.
In case auxiliary device 21 clamps band 9, just can actuate cross-cutter 23, it can cut off the redundance 24 of band 9.This part 24 will drop in the pulper mouth 19 then.Cross-cutter 23 can move to adapt to the former roll coil of strip 16 change in radius, the position change that the former roll coil of strip 16 change in radius can make band 9 hang along the direction shown in the double-head arrow 25.Because auxiliary device 21 can at any time move along mobile route 22, so the position change of band 9 can not influence auxiliary device 21.
Auxiliary device 21 moves to winder station 3 along mobile route 22 then, and guiding band 9 is walked around a plurality of deflection roll 26 up to winder station 3 in this process.Mobile route 22 keep with deflection roll 26-29 at a distance of enough distances, just can be in the operation subsequently required mode of band 9 (its back at auxiliary device 21 is drawn) is on deflection roll 16 like this.But auxiliary device 21 can not collide with deflection roll 26-29.In guiding band initiating terminal, the new former roll coil of strip 16 is movable to expanded position 5.
Cutter sweep has last cross member 30 and lower cross member 32, and last cross member has fixes a cutting tool 31, and lower cross member has bottom tool 33.Lower cross member 32 can move along the direction shown in the double-head arrow 34, like this at the bottom tool 33 of cutting position shown in the dotted line with regard to the crossover position shown in the removable solid line.Therefore slitter 4 has cut state and transition condition, band 9 is cut into a plurality of strip sections when cut state, when transition condition, fix a cutting tool 31 and bottom tool 33 each interval certain distances, the very big so that auxiliary device 21 of this distance at an easy rate through fixing a cutting tool 31 and bottom tool 33 between the zone.
By slitter 4 is closed immediately afterwards, beginning vertical cutting from the short relatively distance of auxiliary device 21 at auxiliary device 21 like this.This distance is 0.5 to 1m.
Auxiliary device is moved further up to arriving the position shown in the 21c, and it makes band contact bearing roller 12.Described all processes so far all carries out with the overall with form, that is to say band 9 with the state of overall with by auxiliary device 21 clampings, be transmitted with the state of overall with and pass slitter 4, and be placed on the bearing roller 12 with the state of overall with.For example controlling band securely there by suction.
Auxiliary device 21c is further rotated up to the part of vertically being cut by slitter 4 and also arrives bearing roller 12 then.Cross-cutter 35 actions afterwards and the band 9 of cut-out between auxiliary device 21c and bearing roller 12.In case band 9 arrives bearing roller 12, it just is positioned known " winding position ".Cross-cutter 35 moves towards bearing roller 12 along the direction shown in the double-head arrow 36 then, and cuts off the band 9 that is positioned between auxiliary device 21c and the winding position (being bearing roller 12).Auxiliary device 21c moves to its initial position once more then.Cross-cutter 35 moved to outside the mobile route of auxiliary device 21c before moving along direction shown in the double-head arrow 36.
In case the band 9 of cutting arrives winding position and just begins to carry out operating winding.Therefore in winding process, auxiliary device 21c can retract its initial position, thereby reduces the time that is consumed.Initial position is positioned at the top of pulper mouth 19, makes to launch to fall into pulper mouth 19 and to handle simply by the unnecessary band that will be wrapped on the auxiliary device 21.
Also lasting rotating driving device (not specifically illustrating) can be set in the winding position zone, and auxiliary device for rotation 21c arrives bearing roller 12 up to vertical cutting part.In this way, can avoid once more mobile auxiliary device 21c so that vertical cutting part is sent to bearing roller 12.
Except saving time, all right saving in material is because the waste of band 9 is less than wedge that uses in the prior art or the most advanced and sophisticated band of being wasted.
Auxiliary device 21a also can be used for making known " butt joint ".For this purpose, the docking facilities 37 that moves along direction shown in the double-head arrow 38 can be set between expanded position 5 and slitter 4.Auxiliary device 21a is used to make the band 9 contact docking facilitiess 37 that launch from the former roll coil of strip 8.Docking facilities 37 is being controlled band 9 securely and it is separated with the former roll coil of strip 8.
Afterwards, the band 9 of the former roll coil of strip 16 that auxiliary device 21 clampings are made a fresh start, and similarly with its guiding docking facilities 37.The end of two bands is connected to each other together there, and for example DE19923097A1 is disclosed.In this case, auxiliary device 21 moves forward and backward along mobile route 22.But in this operation engineering, auxiliary device 21 is only moved along a direction of mobile route 22.
Fig. 2 shows the variant embodiment of rewinding machine 1, and wherein identical and corresponding parts use identical mark.Here launch station 2 and have only the bearing 6 of expansion.When needs are changed spool, for example can move up and pull down the former roll coil of strip 8, to insert the new former roll coil of strip 16.
