Description

Material volume batch up gear and the method that is used to make the material volume

Technical field

The present invention relates to a kind of material volume batch up gear; Wherein can constitute coiling system; This coiling system comprise by winding roller form batch bed, at least one material in forming is rolled up and at least one single-piece or the carrying roller be made up of a plurality of sections; Wherein, winding roller and carrying roller have the wiggle and the appearance profile line that under the power effect, can change in the axial direction.

The present invention relates to a kind of method that is used on material volume batch up gear, making the material volume in addition; Said material volume batch up gear can constitute coiling system; This coiling system comprise by winding roller form batch bed, at least one material in forming is rolled up and at least one single-piece or the carrying roller be made up of a plurality of sections; Wherein, winding roller and carrying roller have wiggle in the axial direction, the influence that stressed effect changes in the process of coiling process of said wiggle.

Background technology

Material twists in this respect can be by vertically being divided into the sub-width of cloth or undivided web generation.

The present invention will be described below in conjunction with the processing of paper web.But the present invention also can corresponding use on other width of cloth of similar operations.Other width of cloth for example are board web, plastics or metallic paper, but this is not exhaustive.

Paper web is produced on paper machine with the highest sizable width that surpasses 11m.Produce and almost carry out continuously.At this, the product service direction of paper machine be in all machine and equipments in the paper mill confirm vertically with horizontal surface on perpendicular horizontal.For simplifying this document, this external suitable part vertically be called X to, laterally be called Y to direction perpendicular to the plane of opening by this both direction be called Z to.On the end of paper machine, the paper web that is produced is wound on the volume core with whole width in first coiling process.This volume core all periodically changing in any case in production run.The volume with fabric width that produces in this manner is commonly referred to parent roll.For later user for example can be operated the printing house, must will batch the sub-width of cloth that paper web on parent roll cuts into a plurality of parallel distributions, its width is applicable to later relative users.These width are looked the particular case meeting, and great changes have taken place, thereby cutting apart usually of paper web carried out according to the cut mode that can confirm individually.The sub-width of cloth is coiled into the material volume then again, exactly, coils into so-called sub-width of cloth volume or finished product volume and also discharges as so-called throwing volume jointly.Cut mode is being thrown volume and is being thrown between the volume and can change.Vertically cut and batch according to purpose and on unique machine, carry out.The batch up gear of equipment is referred to as material volume cutting machine then like this.Therefore this material volume cutting machine mainly is made up of unwinding device, cutting part and wind2, and wherein, cutting part has the blade that constitutes with possible most plate-like of cutting apart the corresponding quantity that cooperates.

Aspect the formation of material volume cutting machine, promptly there is difference in the professional between carrying roller reeler and the anvil roll reeler two kinds of basic structure types.This point also is applicable to this situation, i.e. at least one influence in coiling process, form material volume-just sub-width of cloth volume or finished product volume-winding roller replaced by belt around roller.The characteristic of the carrying roller reeler type of introducing comparatively in detail for example here is a wind2, and wherein whole throwing twists in by what two winding rollers that constitute as carrying roller were formed and batches to be wound on the bed and batch on the sleeve.The sleeve that batches of throwing volume can not have betwixt mountains through clamping head or guide head maintenance, or the winding off spindle that under more rare situation, batches in the sleeve through insertion keeps.The something in common of volume is that as a whole thrower batches.This point is generally batched by circumference and is carried out, and can drive at least one of two carrying rollers for this reason.If can use winding off spindle, so also can carry out central coiling or the two is made up.

Use additional pressure roller generally, these pressure rollers are responsible for batching hardness and in the process that coiling process continues, often bearing stable task of the degree that requires at the initial period that batches at every turn.

For guaranteeing competitiveness also for reaching high quality, people pursue and reach high production speed.In this regard, all devices or the equipment that are in the paper mill production link all are as the criterion with the speed of production of predesignating through paper machine.Because except failure condition, the paper machine continuous working so roll up cutting machine for the material of discontinuous work, is difficult to catch up with the speed that is provided.Because therefore the corresponding frequent appearance of the task that equipment, acceleration and deceleration time and specification reduce also can only remedy through improving speed of production.

This means that material volume cutting machine must produced with the procedural type of " having stopped go further (stop-and-go) " between the volume group under extreme acceleration and deceleration value.In the past few years; The speed of production of paper machine promotes greatly; Hope to adopt unique material volume cutting machine to follow the production of paper machine and satisfy different user for economic reasons, thereby cause present finished product volume to produce with the finished weight between the width range between about 0.2m-5.0m and the hundreds of kilogram to 10 ton to the ever-increasing demand of upper specification limit.The final diameter of finished product volume is about 1.5m mostly, and wherein, the finished product volume greatly different with this size is also very common.In this regard, pursue speed of production and be up to 3000m/min, this speed of production need be at 40m/s ²To 60m/s ²Acceleration and reach between the decelerating phase.

But also have this high request to imply potential excessive risk with relevant therewith owing to vibration occurring to material volume cutting machine to coiling process.The material volume that will produce therefore almost can not form desirable circle.For example owing to the small profile change of paper web that will batch cause batch little error, whenever batching a circle will superpose.Because the periodicity of batching error separately of rotation volume repeatedly, under the situation that depends on its circumference and circumferential velocity, constitute the vibration of corresponding frequencies.

Along with the growth of speed of production, shake increasing frequently (under the situation that circumferential velocity improves, the same position of volume is more and more continually through same volume crack) and amplitude more and more stronger (simultaneously along with coil diameter its out-of-flat of increase and effective weight are also increasing).The material volume of roller in forming that can not control Relative Oscillation then applies fitfull or periodic pulse, and therefore its out-of-flat increases.In this regard, formation is batched error on the one hand.On the other hand, the excitation that causes through material volume itself becomes big once more.

Under the present speed of production situation of pursuing; Almost still do not exist in addition economic utilization possibility be the natural frequency of such designing institute carrying roller of participating in; The possible intrinsic excitation of system is reliably got rid of with superposeing therewith other a large amount of vibration tracers also occurred, these vibration tracers are summarised as one group of vibration tracer that equipment causes.

Mainly receive above-mentioned group, frequent in addition observed other phenomenons appear in the influence of those vibration tracers that just are associated with paper web to be processed basically, and these phenomenons part at least are summed up as each volume freedom of motion relative to each other.Observation shows, reaches or the diameter that batches through about 800mm-1100mm like fruit width of cloth volume, particularly can constitute critical batching the stage.

Summary of the invention

Therefore the object of the invention is, stablizes the state on the bed that batches.Avoid in addition or reduce the appearance batch error at least.The wearing and tearing that people hope to produce special quality material volume and reduce material volume batch up gear.

The object of the invention is achieved according to the present invention thus, and promptly winding roller and carrying roller constitute like this, and its wiggle or its opposed facing appearance profile line can synchronized with each otherly be changed.

In this regard.Phraseology " synchronized with each other " is meant the object that can be synchronized with the movement each other, and just the aspect-stabilized state of winding roller and carrying roller is changing during the coiling process, particularly remaining unchanged under its situation apart from increasing aspect its elastic line or its opposed facing appearance profile line.This means that winding roller and carrying roller move simultaneously of the same typely on size and Orientation.

In this regard, preferably these lines can be straight line or curve, on its spatial orientation, form parallel lines with briefly, its collimation remains unchanged through coiling process, if the distance of said line obviously also increases along with the material volume in forming and becomes greatly.

Therefore winding roller aspect the described line type of observation, carries out consistent motion according to time, size and Orientation.

In this manner, the internal state of coiling system can keep constant all the time and can handle the material volume in the formation ideally.

Wiggle or its opposed facing appearance profile line under the preferred carrying roller peak load correspond to the wiggle under the winding roller minimum load and under minimum load, correspond to the wiggle under the winding roller peak load.

Under these tensioning states, can constitute coiling system according to simple especially mode with alleged advantage.

What have advantage in this regard is; Batch up gear forms through double bracket roller batch up gear and the minimum load of carrying roller is between the 0.1N/cm-12N/cm; Preferably in the scope between the 0.5N/cm-5N/cm and peak load be between the 15N/cm-65N/cm; Preferably in the scope between the 20N/cm-45N/cm, the minimum load of the winding roller that constitutes as carrying roller then then between 0.3N/cm-13N/cm, preferably changes in the scope between the 1N/cm-6N/cm; And peak load preferably changes in the scope between the 20N/cm-80N/cm between 15N/cm-100N/cm.

Experiment shows, under these prerequisites, can produce special special quality finished product volume.In this regard, in described scope, can process extremely different paper product kinds.Situation even show more surprisingly also can be operated highdensity paper like this under quite high pressure.The position (the ply of paper in-to-in crackle that has just batched forms) that hypothesis observation now increases appearance causes through the mutual action of high elongation with through impacting the power that discharges.Paper web stretches many more, dangerous with regard to rising naturally so.

But through foundation device of the present invention, the material volume in the formation obtains good guiding, to such an extent as to almost can not constitute the impact of being worth mentioning, forms thereby also can not occur crackle in layer or the paper web batching of high elongation.

What have advantage is to have at least one device, utilizes it initiatively to influence at least one wiggle or at least one appearance profile line towards the coiling system center according to shape and/or size.

In this regard, preferably can influence all wiggles or synchronously towards the appearance profile line at coiling system center.But it is contemplated that also only unique roller line distributes with the line of other rollers and cooperates, so that the collimation through whole coiling process maintenance space.The type of the amplitude of the sinuousness that in this regard importantly, can measure on the line type separately is identical identical with size.

In this manner, keeping under the desired line states situation, also the volume of the material in forming applies local different pressure especially simply.Therefore on the Y direction, observe, can avoid different material volumes to increase especially effectively.This point particularly is suitable for material volume batch up gear has the situation of cutting part as following further introduction is under.

What have advantage in addition is, the circular movement of the material volume in forming on the circumference of the material volume that a single at least section of pressure roller or pressure roller can be in formation in the process of coiling process or around at least one.

In this manner, the state in can the additional stability coiling system.

At least one section of preferred pressure roller or pressure roller is preferably constituting with the synchronously driven mode of winding roller.This point particularly constitutes common batching under the situation at other winding rollers and has advantage.

In this manner, can added influence and stablize the material volume that forms in the coiling system particularly well.Preferably pressure roller or its section have the elasticity lining for this reason.

Preferred material volume batch up gear has cutting part, and the web that wherein can on material volume batch up gear, operate for formation material volume can be divided at least two sub-width of cloth in the vertical.

In this regard, cutting part preferably has a large amount of adjustable separation members, is used for that the sub-width of cloth that produces from web is carried out other form and selects.

In this manner, can from web, produce the sub-width of cloth, this a little width of cloth can coil into the sub-width of cloth volume of common formation then.In this case, can use especially effectively, because handle the oscillation problem that the sub-width of cloth volume that constitutes side by side in most cases can cause especially severe according to material volume batch up gear of the present invention.

What have advantage especially is, the roller that forms coiling system contacts through roll gap with the material volume, wherein, preferably has sensor then, can be intermittently or the roll gap of METHOD FOR CONTINUOUS DETERMINATION maintenance and preferably act on the power of roll gap through these sensors.
