Description

Batch the batch up gear of fiber web continuously

Technical field

The present invention relates to a kind of fiber web that makes and center on the batch up gear that spool is wound into machine rolls continuously, this batch up gear comprises: reel, and it forms nip with the machine rolls of being reeled; Support frame, it is set to be used to support machine rolls, and by this support frame, as the core of machine rolls and the spool that operates can move along directions X, in batch up gear, fiber web can swingingly be wound into machine rolls thus.

Background technology

Batch up gear is with the device of the material webs coiled of producing continuous fiber width of cloth material as the roll form of machine rolls.In the production process of fiber web, batch normally first subprocess, thereby wherein continuous production is interrupted continuation successively.Machine rolls forms around the spool of operating as the volume core, promptly is in a fiber web on the machine rolls and has top and end.The trend in this field is that the size of machine rolls increases constantly, and this claims for the exploitation batch up gear.In fact the size of spool has specified the upperlimit of machine rolls.Yet because we are to the concern of dynamic environment, and fiber web is the rollable material that is subject to the various faults influence, so by quite important as the performed task of the batch up gear of the efficient retainer of paper machine or lap machine.The reason that the size of machine rolls increases continuously is to hope in the production of fiber web, to realize starting and termination still less, these startings and end to hinder or upset production process and lower efficiency.

Simultaneously, described a kind of method among the patent FI91383 (EP0483092B1), this method is transferred to new order with the size of machine rolls, and can with good mode form the beginning of machine rolls from the angle of the attribute of the fiber web that batched this moment.When the quantity of the fiber web that batches increased, the importance at beginning increased, and operated as " basis " of volume structure because should the beginning.At this, develop this technological key feature and be by main center driver and subcenter actuator to be the advanced person's that provides of machine rolls center moment of torsion, this makes it possible in the process that forms machine rolls, use many-sided parameter of batching.Prior art before this device is a so-called Pope surface reel device (Pope reeler), wherein form machine rolls through machine rolls being pressed against the driving reel, so machine rolls forms by the friction between reel and the machine rolls.

The method of describing among the patent US5370327 has been introduced on a vertical plane idea that forms machine rolls for the first time, makes this machine rolls in whole coiling process, be on the top of horizontal rail of identical vertical height.Patent documentation FI91383 has also described such device, but before beginning to batch, spool moves to reference position with the mode of Pope formula (Pope-type).In patent US5370327, the reel that moves can remain on the constant plane center of spool.The advantage of this device is from being present in the load of load transfer to the side of the reel that is present in mass conservation on the machine rolls side to the adjusting of nip forces.

Except " pioneer's patent " of above-mentioned second generation batch up gear, also have various embodiment, these embodiment have further improved the theory of in these two patents, describing.One in them is patent US6354531, and it has been described fiber web swingingly is arranged into a plurality of different flexible program in the machine rolls.The specification sheets of patent WO2007/010094A2 has also been described some possible devices that are used for swingingly batching fiber web.

In the continuous coiling device of listing, the swing in secondary the batching is through making machine rolls and reel turn to (that is fiber web is turned to) and generation along machine direction.This is described in the specification sheets of patent DE19939506 in more detail.This device needs movably reel, therefore can influence the Tension Distribution of fiber web on the horizon.

In the continuous coiling device that applicant's the name with OptiReel Plus is sold, machine rolls along teeter, makes and moves along the Y direction simultaneously along the parent roll slide unit (sledge) of directions X mobile apparatus volume and support load during secondary batching.

In describing context of the present invention, following term is used to make to be described conveniently: machine direction (MD) is meant directions X, and laterally (CD) is meant the Y direction, and highly is meant the Z direction.The incoming direction of fiber web is meant updrift side, and the outflow direction of fiber web is meant downstream direction.The volume core is meant spool in context, but it also can be called winding off spindle.

Summary of the invention

The objective of the invention is to develop a kind of device that can batch simple and reliablely,, can swingingly batch fiber web when needed by this device.The present invention also aims to provide a kind of device, its theory of batching is based on the known method that forms machine rolls by reel.

Batch up gear according to the present invention is characterised in that support frame is arranged to can move along the Y direction with respect to framework, is used to provide the swing path of spool, and support frame combines with actuator, is used for producing moment of torsion in machine rolls.

Therefore, the teeter of machine rolls is to control through the side travel that the support frame that makes supporting reel is followed along machine rolls.The bearing portion of low friction is set below support frame, in bearing portion slidingsurface each other against and slide delicately.To this valuably, between support frame and framework, plane sliding bearing is set, so that support the load that the quality by machine rolls causes.

In concrete embodiment, support frame is connected to subframe, between support frame and the subframe or between subframe and framework, be provided with plane sliding bearing, and the load that causes in order to the quality that supports by machine rolls.In addition, in the device according to useful embodiment, the element as the control track moves is provided with the control guiding device, in order to control roll track moving along the Y direction between roller track or subframe and framework.Relevant with the present invention; Framework refers to such part of batch up gear; It is static that said part is set to respect to building, and via said part, and the load that is caused by the quality of machine rolls and the actual mass of batch up gear are supported by building by transmission.

The fault that the narrow afterbody that the abundant swing of machine rolls has reduced fiber web causes the structure of batch up gear or machine rolls.These comprise: become difficulty or hindered of the discharge of the air that produces from the end of machine rolls; In the machine rolls of fiber web, form to stretch striped or other is equal to problem.These possible problems increase (that is, this influence occurs again and again) along with the increase of machine rolls diameter.Usually, this swing (wherein, during batching, fiber web departs from several centimetres to about ten centimetres along the Y direction from an edge to another edge) is enough to overcome the problem that is caused by striped.For fiber web is not unnecessarily stretched because of swing, the wobble length that is fit to of setting fiber web also is very important.Wobble length L _Osk=v*t _Osk, wherein v is a speed of production, and t _OskIt is the time of accomplishing an oscillating traverse motion.For example, the cycle of wobble cycles is 1.5 minutes, and the speed of production of fiber web is 1800m/min, and then wobble length is 2700 meters, and this in most of the cases is sufficient.
