Technical field
The present invention relates to a kind of suction roll system, it has rotationally supported cylindrical suction roll, the cylindrical jacket of this suction roll is provided with multiple sucker especially forming poroid seam pattern, and these suckers individually or in groups can be connected with low-pressure system selectively by control system.In addition, the invention still further relates to one and be used for the device of rapidoprint breadth (especially paper web face or cellulose breadth).
Background technology
In paper conversion or cellulose processing industry, often material web is processed.At this, such as, when manufacturing envelope, printed matter or similar object, paper web face is supplied to another processing stations, wherein by the cutting of paper web face, flanging, printing or be otherwise processed into single material block.Equally, such as when manufacturing handkerchief, cellulose-fiber web will stand other procedure of processing, is wherein suitably cut into the size of expectation by cellulose-fiber web or other hygienic article, carries out suitably flanging and packaging subsequently at this material block obtained.
Process these material webs and cut by material web or separate plane material block time, this material usually be used for process device in guided by multiple transmission or processing unit (plant).In this context, often go back application function roll, material web also or material block guided by these function rolls and realize turning to, also maybe may just realize support.On demand, this function roller can arrange cutter sweep, pressure setting or similar device, satisfactorily can process material when each material is operated by roll.This function roll also or function roller can be designed to so-called suction roll system at this, the material operated by these rollers is satisfactorily inhaled on function roller or function roll by this suction roll system, therefore, it is possible to adhere to the material guided by roller or roll well.
The known this suction roll system of such as DE 10 2,009 033 575 A1, it comprises rotationally supported cylindrical suction roll usually, the cylindrical jacket of this suction roll is provided with the sucker of the poroid seam pattern of multiple formation or inhales seam, and they individually or in groups can be connected with low-pressure system selectively by control system.By suitable control, single sucker or the sucker group selected purposively are connected with low-pressure system at this, and therefore this material is inhaled and is also therefore fixed on above it on suction roll within the scope of the sucker controlled respectively.
In order to realize controlling, these suckers are connected with the side of roll body by the system of suction channel usually at this, these suction channels in the inside of roll body along its longitudinal direction guide and on the position of each sucker radially outward fork and by respective sucker.Side is corresponding therewith, and so-called control head is arranged in the fixed mount of suction roll, and this control head has some and controls aperture, and they self are connected with low-pressure system.The situation that may occur when suction roll rotates is, the side outlet of each suction channel is salty folded with the control hole in control head, and therefore corresponding sucker is connected with low-pressure system in this case.Therefore low pressure can satisfactorily be connected when suction roll rotates and again disconnect in respective sucker, and therefore each sucker can load low pressure by rhythm exactly.
But these suction channels have the ratio of relatively disadvantageous length and cross section usually in such systems, therefore the gas exchanges in each suction channel subjected to relatively high flow resistance when changing between low-voltage and normal pressure pattern, and sucker and control head couple together in low-pressure side by this suction channel respectively.Therefore, when jointly or side by side controlling multiple sucker in groups, can only limit as the free degree by this system accessible turn-on time.
Summary of the invention
Therefore the object of the invention is, a kind of suction roll system of the above-mentioned type is described, of short duration conversion time can be realized in a reliable fashion by it, even if also high flexibility can be realized when controlling multiple sucker in groups in addition.
For realizing this object, the present invention is by following realization, namely control system comprises hard-wired, the hollow circular cylinder put in suction roll, its cylindrical jacket is bored a hole by multiple control slit, and this set-up of control system must be used for optionally single or multiple sucker or suction seam being coupled together with low-pressure system.
The present invention is based on such thinking, channel geometries when accessible conversion time and the possible process speed of whole system depend on that sucker is connected with low-pressure system to a great extent when controlling sucker or inhale seam.Especially in order to realize of short duration conversion and control time, effort maintenance interface channel is short as far as possible and channel cross-section is wide as far as possible.Specify for this reason, be positioned near sucker region by the area of space (being the control head in the carrier of suction roll in existing system) loading low pressure consistently, the interface channel therefore between sucker and permanent depression can keep especially short as far as possible self-consistentency.
In order to realize this point, arrange the hollow circular cylinder put in suction roll, its inner space should load by low pressure enduringly when device operates.Therefore in order to " connection " sucker, the connection of only build-up pressure side between low-voltage space (i.e. the inner space of hollow circular cylinder) and each sucker is gone back.Therefore for this reason required control channel only penetrate the cylindrical jacket of hollow circular cylinder; On the contrary, the longitudinal direction of the suction roll at the channel range and little channel cross-section with corresponding length is not needed to carry out passage guiding.In order to control sucker at this, namely control the connection of the low-pressure side of the inner space of itself and hollow circular cylinder, hollow circular cylinder and cylindrical jacket thereof have multiple control slit.If each sucker controls slit because the rotation of suction roll extends beyond one of them, then achieve described control, namely achieve the connection in low-pressure side of each sucker and low pressure chamber.
This sucker or each sucker can both have circular aperture cross-sectional, and therefore it is substantially identical with the hole of routine.Alternatively, such as, according to the position of sucker on cylindrical jacket and for realizing the aspiration feature reaching expectation when operating, this sucker also can arrange the suction face of the active of other structure, and its form is such as inhale seam or similar object.Concept " sucker " should comprise the geometry of this change in statement.
Advantageously, slit is controlled respectively in the circumferentially extension of cylindrical jacket.Therefore by the position of each control slit, especially according to its starting point and terminal and length in a circumferential direction, the control time of the expectation for each sucker can suitably be adjusted in advance.Therefore particularly by suitably locating multiple control slit (they may be different from each other in the correlation of starting point and/or terminal), can the prespecified control pattern for whole sucker, therefore by being correspondingly placed in the cylinder wallboard of hollow circular cylinder by suitable control slit, the sucker that can realize device technique is especially suitable controls pattern.Such as selected by the suitable width of each control slit at this, also can control multiple sucker in groups, wherein its especially such size up on width, namely multiple sucker of placing successively at the longitudinal direction of suction roll jointly extends beyond respective control slit.
Can reach especially high flexibility when operating multiple sucker in groups at this, its mode is: in especially favourable structural scheme, suction roll is configured to the form of the distribution passage for low pressure in the region of its cylindrical jacket guided for passage.For this reason, the distribution member that another is designed to from main member can be set, or the cylindrical jacket of suction roll can design and for solid, to form this distribution member on it enough thick.The distribution member formed by this deformation program is in this preferably design like this, and namely it is connected with the multiple suction pipes suitably selected respectively in low-pressure side.For this reason advantageously, suction roll comprises by its distribution outer cover round the rotatable supporting of hollow circular cylinder to form this distribution member in inner side, and it is bored a hole by multiple distribution passage.The guiding of passage is distributed by these, the sucker being subordinated to each distribution passage at outlet side can be subordinated to according to the prespecified of personalization the control slit selected separately, wherein especially also can be guided by suitable passage in the sucker of the longitudinal direction of roll and each control slit locations spaced and couple together with respective control slit.By this way, guided by suitable passage, during the pattern of the control slit in the cylindrical jacket presetting hollow circular cylinder, can reach relative complex, personalized with each dress technique and the control pattern that matches of the Control requirements of consequent sucker.
In especially favourable improvement project, this design can be used to especially control sucker in groups at the longitudinal direction of suction roll.Specify aptly, these distribute at least several cross sections had from interior towards external expansion in passage for this reason.This distributes passage or each distribution passage has the cross section extended on the longitudinal direction of suction roll especially aptly on the lateral surface distributing outer cover, multiple sucker set gradually at the longitudinal direction of suction roll can be connected on one or same distribution passage because distribute passage by these.Respective distribution passage can be provided with size and set to obtain the cross section of relative narrowness in inner side, its form is such as hole.If the hole, inner side respectively distributing passage in this embodiment when suction roll rotates round hollow circular cylinder has extended across the control slit being placed in hollow circular cylinder, then the distribution passage therefore on all outsides and the sucker that is attached thereto are simultaneously and load by low pressure synchronously with one another.
In especially preferred structural scheme, suction roll system designs be used for changing respective parts especially easily at this.For this reason advantageously, put in hollow circular cylinder in suction roll only to go up and bearing structure is fixedly linked at an one side (especially its mounting end).The other end of hollow circular cylinder is closed in side hermetically by suitable lid aptly, and this end is advantageously placed on the driving flange outstanding forward of driver element regularly at this.In this preferred embodiment, this suction roll and may from inner side be arranged on distribution outer cover this suction roll from shift onto above drive flange (especially motor flange) axle, and to be substantially bearing in completely above this.As required, extra supporting can be carried out by the supporting system be arranged on the mounting end of hollow circular cylinder.Such as maintain or repair work to carry out, also or in order to match with the requirement of device technique suction roll is set with the sucker changed poroid seam pattern, by this " the movable supporting " of suction roll, parts can be changed in especially simple mode, its mode is, suction roll and may be arranged on the distribution outer cover inside it and therefrom pulled out by the free end of hollow circular cylinder and can replace by substitute part.At this, equally by being arranged on the connected system on mounting end, the inner space of hollow circular cylinder can be connected in low-pressure system.
These suckers can be arranged in the cylindrical jacket of suction roll with the form of poroid seam pattern on the whole.But in especially favourable structural scheme (it also regards content of the present invention as), the cylindrical jacket of suction roll is formed in the mode of many bodies, wherein the single local surfaces of cylindrical jacket is designed to independent, removable component, and they carry multiple sucker respectively.In this especially preferred embodiment, wherein the cylindrical jacket of suction roll has some outer cover laths, this outer cover lath releasably with originally or " inner " suction roll body be connected and be respectively arranged with some suckers.At this, by each sucker or inhale the suitable location of seam and/or size setting and/or shape and select, outer cover lath is formed and the suction pattern of function match, and each process and the requirement of it and device technique match.Such as outer cover lath can be configured to so-called suction lath, and it is substantially provided with suction hole and fixes the section source, each portion of handkerchief portion section when processing of cellulose-handkerchief product.But outer cover lath also can alternatively be designed to flanging lath, sucker and suction seam combine and fix handkerchief portion section when upset or flanging by it, therefore form the new front edge of handkerchief portion section after the flop at this.
By this structural scheme, in order to regulate or change the poroid seam pattern be made up of the sucker on the surface of cylindrical jacket, then need only be changed this with the form design of shadow shield, such as by the fixing component that is threaded.On the contrary, suction roll other component, especially there is the matrix that distributes the low-pressure system of outer cover and the script of suction roll or inside subject can remain unchanged.Therefore, it is possible to regulate suction pattern or poroid seam pattern in especially simple mode.
In another same especially preferred embodiment, in order to especially satisfactorily treatment paper breadth or cotton paper breadth, this suction roll system can purposively keep relatively low to the requirement of required low pressure.In this preferred embodiment, whole suckers in the cylindrical jacket of suction roll (also or at least partly sucker) are all provided with the cross section that the outer surface from the inner surface of cylindrical jacket towards cylindrical jacket is expanded.Also preferred and what regard content of the present invention as is such embodiment of suction roll system, namely one or several in this embodiment in these suckers has cross-sectional profiles in its outboard end, in this cross-sectional profiles, suction face surrounds supporting surface at least partly, and this supporting surface is almost positioned in the outer surface of the cylindrical jacket of suction roll.
Its based on theory be, what the reason expectation due to technology reached is, low pressure (namely different from normal pressure in amount) needed for implementing process is kept relatively low, because can will keep relatively low to the requirement of sealing system and similar object by this way.In equipment, this scavenging period also therefore, it is possible to reliably carry out with relatively low cost, but conversion and the reaction time shorter.But in order to plain existing reliable technique guide by relatively low low-pressure water, wherein especially on suction roll, be reliably applied for the confining force needed for fixing paper web face or material web by low-pressure system, therefore the size of effective suction face (i.e. penetration surface) of each sucker should set enough large, and low pressure is applied on material web on the surface of suction roll by this suction face.
Note also but then, when effective suction face sets too large, distortion may be occurred in material web, especially when this material web is relatively soft cloth material.This distortion can cause packing less situation when sucked material, and this may have a strong impact on the carrying out of technique.In order to overcome this point, roller surface in each suction areas should take the following form of the composition, namely suction areas (i.e. the regional area of effective suction face of each sucker) is located directly adjacent with supporting surface, and material web is suitably stablized and is fixed in this supporting surface.For this reason, being used for the supporting surface of backing material is positioned at the directly adjacent place of each suction face, and material can suitably lie on this supporting surface in order to avoid distortion (such as folding line).Advantageously, this suction roll system is applied in the device for rapidoprint breadth (especially paper web face or cellulose breadth).In this device, material web or fiber speed breadth are guided by multiple function roller or function roller, and therefore this function roller or each function roller are designed to the suction roll of described type.
This suction roll system especially can be applied in the field of the handkerchief portion section of the band shape of processing health product, pre-flanging at this.They are held by the cylinder of the expansion bearing be made up of suction roll, and wherein due to the structure of above-described suction roll system, vacuum and air are radially supplied to suction hole.These handkerchief portion sections in the apparatus single or multiple ground, transverse to its direction of motion flanging, and are forwarded to other processing stations.This single product department's section remains on cylinder or suction roll circumferentially at this preferably by multiple row suction hole, and they are arranged on this roller or roll transverse to the direct of travel of product department's section.
The advantage reached by the present invention is especially, can keep especially short by conversion distance by control system being configured to the hollow circular cylinder stretched in suction roll, sucker is connected with low-pressure system when manipulating by this conversion distance.Therefore, while raising reliability, especially short control time and corresponding high process speed can be realized.By distributing the especially preferred intermediate conversion of outer cover, can when maintenance compared with when jitty length flexibly and precise synchronization control multiple sucker.Therefore, it is possible to controlling pattern by technique restriction ground by desirably changing, with regard to distributing the guide being arranged on its inside of passage, need only change in this control pattern and distributing outer cover.

Suction roll system 1 can be used as in the device of each function roller or function roll on arbitrary position, this suction roll system purposively designs be used for reliably at this and controls single sucker accurately, and material web or respective material block temporarily can be fixed on outside roll by this sucker.For this reason, this suction roll system comprises hollow circular cylinder 2, and it is connected regularly with the bearing structure be not shown specifically on its end 4 (hereinafter referred to " mounting end 6 ").Drive motors 8 and carrying flange 9 are arranged on this bearing structure, and hollow circular cylinder 2 can be shifted onto on this carrying flange 9.The inner space 10 of this hollow circular cylinder 2 to be connected to by the sleeve pipe (Durchf ü hrung) 11 arranged on mounting end 2 in the low-pressure system 14 that Fig. 1 represented by vavuum pump 12 at this.
Hollow circular cylinder 2 carries out wiper seal by lid 18 on its free end 16, and this lid 18 can be designed to independently component also or form the part of cast body of hollow circular cylinder 2.The cylinder outer cover 20 of hollow circular cylinder 2 is bored a hole by multiple control slit 22, and the inner space 10 of hollow circular cylinder 2 controls slit by these and is on the pressure side being in connection status with space outerpace.These control slits 22 in this circumferentially extension at hollow circular cylinder 2 and cylinder outer cover 20 thereof.
Suction roll system comprises distributes outer cover 30, and it is arranged on the inside of cylindrical suction roll 32.This distribution outer cover 30 this can be designed to autonomous, push in suction roll 32 and and be suitably fixed on the component at this place.In an embodiment, outer cover 30 is distributed by the script of suction roll 32, suitably thickening and be designed to solid cylindrical jacket 34 and form.
The cylindrical jacket 34 of suction roll 32 is provided with the sucker 36 forming poroid seam pattern on the whole on its outer surface, and the material lain on the surface of cylindrical jacket 34 can be picked up by these suckers on demand.Suction roll 32 is provided with lid 38 in side.In addition, the cylindrical jacket 34 of suction roll 32 is designed to many bodies, is wherein designed with single local surfaces in its surface, and as outer cover lath 40 that is independent, that form desirable lower member, they carry multiple sucker 36 respectively.These outer cover laths 40 this releasably by suitable be threaded with cylindrical jacket 34 (its form originally or the suction roll body of " inside ") be connected, and in order to fix in the suitable groove of insertion cylindrical jacket 34 in local positioning and side.
At this by each sucker or inhale the suitable location of seam and/or size setting and/or shape and select, outer cover lath 40 is formed and the suction pattern of function match, and each process and the requirement of it and device technique match.Such as outer cover lath 40 can be configured to so-called suction lath, and it is substantially provided with suction hole and fixes each end of handkerchief portion section when processing of cellulose-handkerchief product.But outer cover lath 40 also can alternatively be designed to flanging lath, sucker and suction seam combine and fix handkerchief portion section when upset or flanging by it, therefore form the new front edge of handkerchief portion section after the flop at this.
As marked by arrow 42, suction roll 32 is shifted onto on hollow circular cylinder 2 when suction roll system is installed, and therefore, hollow circular cylinder 2 stretches in suction roll 32 under the installment state of suction roll system.Suction roll 32 is fixed on mounting end 6 in side on the contact surface 43 that driven by drive motors 8.When suction roll system 1 is run, described contact surface 43 is placed oneself in the midst of among the rotation of the longitudinal axis of suction roll system, and therefore suction roll 32 also can correspondingly rotate round its longitudinal axis by it.In order to realize supporting, suction roll 32 is bearing on sliding axle carrier ring 44 at this, and this sliding axle carrier ring is arranged on hollow circular cylinder 2 from side.Therefore achieve substantially " supporting actively " of suction roll 32, the sliding axle carrier ring 44 that wherein main supporting force is installed by side receives.In order to realize extra guiding and stablize when needed, the free end of reach 9 can also be arranged and guide bolt 45, its embed corresponding, inner side, be arranged in lid 38, not shown groove from centre.
The distribution outer cover 30 be integrated in the cylindrical jacket 34 of suction roll 32 is bored a hole by multiple distribution passage 46.At outlet side, namely towards the region of the outer surface of cylindrical jacket 34, the below of the flanging lath 40 belonging to each distribution passage 46 leads to separately, and be therefore subordinated to the suction hole 36 being placed in each flanging lath 40.Therefore each distribution passage 46 establishes gas side and connection on the pressure side being subordinated to respectively between its suction hole 36 and the inner space of cylindrical jacket 34 of suction roll 32 in the mounted state.
Under the installment state of suction roll system, if being namely provided with the suction roll 32 distributing outer cover 30 from inner side shifts onto hollow circular cylinder 2, then control the sucker 36 of suction roll 32, if namely extend beyond one of them control slit 22 because suction roll 32 and the distribution outer cover 30 be arranged on inside it rotate round hollow circular cylinder 2 aperture, inner side distributing passage 46, then each sucker 36 is on the pressure side being connected with low-pressure system 14.In this case, between the inner space 10 and sucker 36 of hollow circular cylinder 2, establish connection on the pressure side, this sucker is connected with each distribution passage 46 in outside.
As can be learnt under the installment state from the suction roll system in the longitudinal sectional drawing of Fig. 2, distribute passage 46 and there is cross section from interior towards external expansion respectively, wherein distribute passage 46 and there is the cross section that the longitudinal direction along suction roll 32 extends on the outside distributing outer cover 30.These distribute passages 46 in this like this setting size and measurement, and namely according to the application purpose of regulation separately, they are connected with one or more in sucker 36 in a longitudinal direction.
Therefore this suction roll system forms the roller system of expansion bearing, wherein due to the structure of above-mentioned distribution passage 46, vacuum and air is radially supplied to suction hole 36 relative to suction roll 32.These pass through channel system air feed for the single suction hole 36 (they laterally extend on width) of product department's section by distribution passage 46, and this channel system is arranged in distribution outer cover 30 in the below of the product plane that the outer surface of the script by suction roll 32 is formed.According to conception, therefore the outer surface 50 distributing outer cover 30 forms the second plane of passage guide.It communicates with access aperture 62 by distributing passage 46 in vacuum or air side, and this access aperture is arranged on this distribution passage from inner side, and this access aperture is positioned on the inner surface 54 of distribution outer cover 30 in the mode of the 3rd plane.These access aperture 52 especially can be located at the longitudinal direction of suction roll 32 changeably at this, and its position independently can be selected with affiliated suction hole 36.
At this, vacuum or air side arrange, connection between each access aperture 52 and the suction hole 36 being subordinated to it realized by the suitable passage guide distributing passage 46.The respective access aperture 52 control slit 22 corresponding with it is arranged in hollow circular cylinder 2 matchingly, and this hollow circular cylinder is positioned at inside and plays control volume or control flange.Respective control slit 22 suitably carries out selecting and setting size for affiliated suction hole 36 circumferentially seeing in starting point and terminal and length of roll at this within the control time expected.
Respective control slit 22 by give prominence to, the framework frame of bulge shape lives, the aerated area of vacuum area and air is separated by this framework.
This suction roll 32 or cylinder are contactlessly rotated by the control flange surface be made up of the outer surface of hollow circular cylinder 2 together with distribution outer cover 30 (it is arranged on suction roll in inner side).
Guided by the passage distributing passage 46, particularly by its moulding, achieve relatively uniform, short and small channel cross-section by all to be arranged by the suction suction that forms of hole 36, and therefore achieve and be conducive to the length of quick-replaceable gas and the ratio of cross section.Therefore, it is possible to realize ventilation and of short duration conversion time especially fast, but also useful volume and dead center volume are kept especially low.
In addition, cylindrical jacket 34 is also provided with cleaning systems.Its theoretical foundation is, removes the particulate that may stick on surface and material remains by compressed air.For this reason, hollow circular cylinder 2 is equipped with for compressed-air actuated passage.It leads in such hole at outlet side, and namely this hole is arranged in the bulge shape border between area of low pressure and atmosphere zone, and the service duct therefore in Rotating outer can load compressed air.At this, especially define the both sides of tap and the layout of symmetry, the compression shock of both sides can be applied in the middle of roll.This pressure pulse this can automatically especially with system cadence synchronization ground or manually trigger.
As figure can draw from the view of the flanging lath 40 of Fig. 3 and 4, suction roll system is also by suitably selecting geometry and being realized by the moulding of the surface profile in sucker 36 scope, to realize the low pressure level keeping relatively low, established technology pressure is relative subnormal pressure only.In addition, by keeping especially of short duration conversion and reaction time implement scavenging period.But in order to guide by the plain existing reliable technique of this low-pressure water keeping relatively low, wherein especially on suction roll 32, be reliably applied for the confining force needed for fixing paper web face or material web by low-pressure system 14, the discharging area at each suction hole 36 is suitably formed and configures in geometry.
On the one hand, sucker in the cylindrical jacket 34 of suction roll 32 36 (in this embodiment in each flanging lath 40, it forms the local surfaces of the outer surface 60 of cylindrical jacket 34 in the mounted state by its lateral surface) is for this reason by from the inner surface of cylindrical jacket 34 towards the cross section realization that the outer surface of cylindrical jacket 34 expand.On the other hand, in the embodiment regarding suction roll system 1 of the present invention as, sucker 36 is formed like this at this, namely it has cross-sectional profiles in its outboard end, in this cross-sectional profiles, suction face 62 surrounds supporting surface 64 at least partly, this supporting surface on its height (namely with regard to its towards the medial axis of suction roll 32 spacing with regard to) be almost positioned in the outer surface 60 of the cylindrical jacket 34 of suction roll 32.Therefore form such geometry and profile, being namely used for the supporting surface 64 of backing material is positioned at the directly adjacent place of each suction face 62, and material can suitably lie on this supporting surface in order to avoid distortion (such as folding line).
