There is the Galette unit for the induction coil layout structure heated
Technical field
The present invention relates to a kind of Galette unit of roller shell with cylinder, this roller shell can be by means of Fixed induction coil layout structure heats.
Background technology
Heated godet is used for heating in field of textile industry and guides at least one threads Or band.Roller shell generally rotates with the peripheral speed of up to 8000 meters [m/min] per minute.In existing skill In art, on the one hand the known various different systems for heating roller shell, wherein can realize from outside adding Heat, but the most preferably by being positioned at the parts realization heating within roller shell.Document DE 195 40 905 A1 describe a kind of such arrangement, in this arrangement, is positioned at roller shell The fixed induction coil in portion can generate electric current, this electric current heating roller shell in roller shell.This Invention is derived from this arrangement, and this arrangement also describes, how can the roller of spinning in the future The measured temperature of set is outwards transferred to fixed device.
Have a lot of other for inductively heating roller shell by being arranged in the induction coil within roller shell Form of implementation.The common ground of all these forms of implementation is, applies ferromagnetic material the most always Material, the most stacked plate or ferritic form, in order to conduct in roller shell as fully as possible The magnetic flux of induction coil.This situation needs to expend substantial amounts of material, and causes induction type to add thermojunction Structure is the heaviest and expensive.But it is required that this way is counted as up to now, in order to avoids Other parts in heat driven axle and Galette unit, and as efficiently as possible roller shell is realized heating.
Summary of the invention
It is an object of the invention to, weight more lightly designs, with cost, the sense being positioned in roller shell inside lower Answer formula heating arrangement, and and increase loss indistinctively.
It is used for realizing above-mentioned purpose according to the Galette unit described in independent claims 1.Can be independent Application or with the favourable design of technical significant mode combination application at dependent claims Middle explanation.
According to Galette unit of the present invention have by ferromagnetic and conduction material make, Cylindrical heated roller shell, this roller shell has thickness and for heating and guiding at least one root length Silk or the periphery of band, and this roller shell surrounds an inner chamber, has can revolve in center arrangement in this inner chamber The drive shaft turned, roller shell is fastened in this drive shaft by outer side, and this Galette unit also has Induction coil layout structure on bobbin, between drive shaft and roller shell, fixed, Wherein, this bobbin is made up of nonconducting and nonferromagnetic material, and bobbin and drive shaft With roller shell arranged concentric, wherein, except drive shaft be probably ferromagnetic in addition to, in inner space It is substantially absent from ferromagnetic material.
Coil arrangement according to the present invention is that so-called " centreless " or " iron-core-free " is arranged Structure, that is, there is not the built-in fitting of inside conduct magnetic field at roller shell.Surprisingly, The built-in fitting omitting conduct magnetic field can't cause loss to significantly increase, and is also not result in other component It is heated in a larger amount than roller shell.In fact according to the invention, it is possible to use the coil being made of plastics Frame, the most whole induction coil layout structure ratio has the least according to the bobbin of prior art Weight.But surprisingly, glass is also proved to be applicable material.Glass tube can be with cost Manufacture cheaply, and than most of working of plastics, there is more preferable heat resistance, even if thus glass is non- Often can also apply inside godet at a temperature of height.Apply following category of glass in an advantageous manner Type, this kind of glass is modified and is specifically designed at such as 100 DEG C to 200 DEG C or even 300 DEG C Apply under high temperature.So far glass is not also considered as material parts in godet inside, this Being because those skilled in the art to think, the different thermal coefficient of expansion of metal and glass is disadvantageous. But bobbin is the most only fixed in side or energy elastic clamping, thus bobbin is in the axial direction Can expand independent of miscellaneous part.And bobbin only need to support coil, owing to coil has had Balance, thus coil self does not produce extra load to glass tube in the case of high-revolving. It addition, the cost of the substantially cylindrical bobbin being made up of glass is stacked significantly less than using The material cost of transformer silicon steel sheet and assembly cost.From this, do not using conduct magnetic field Device in the case of, be even capable of the highly uniform sensing heating to roller shell.According to this Bright being preferably used following induction coil layout structure, this induction coil layout structure has at least one Be concentrically surrounding drive shaft extend coil, this coil can with there is prespecified frequency and/or electricity The AC power of intensity of flow connects.
The most from the prior art known cylindrical coil basic arrangement and by AC power Power supply.Cause inductivity to be slightly reduced although omitting ferromagnetic coil core, but this can pass through It is appropriately modified AC power or is compensated by improving frequency.Therefore the present invention only need to be known Current supply device and control to carry out small change on device.
Loss can be made in the case where there to be maintained at the most small degree, i.e. work as induction coil layout Structure is spaced apart with roller shell by outer annular gap, and induction coil layout structure is by between inner annular Gap is spaced apart with drive shaft, when this outer annular gap is significantly less than internal annular gap.Thus, line Magnetic density within Quan is relatively small, and the magnetic field concentration of the outside of coil arrangement is in roller shell. The size of internal annular gap is preferably at least twice in outer annular gap, especially outer annular More than five times of the size in gap.
In currently preferred form of implementation, drive shaft at least has electric conductivity in the inner chamber of roller shell Good coating, coating the most made of aluminum.
This point such as can have the aluminum pipe realization of 0.1 3mm thickness, this aluminum pipe cover by installation On the driving shaft.Because drive shaft is generally made up of the material conducting electricity, the most even by ferromagnetic Material is made, so magnetic field also produces electric current in drive shaft and adds in the inside of coil arrangement This drive shaft of heat.Although owing to the such situation of the size of internal annular gap is slight journey Degree, but the most undesirable.The coating (it such as can be realized by aluminum pipe or copper pipe) of good conductivity The vortex flow on surface is formed, this vortex flow magnetic field to producing this vortex flow due to small resistance Have the opposite effect, and therefore by this magnetic field as excluded the region of drive shaft.Although this surface can become Heat, but it is intended to fainter much to the heating of whole drive shaft than in the case of otherwise.
According to the present invention, coil arrangement is designed to realize its purpose, in this coil or institute State the dynamic alternating current of these coil midstreams and produce alternating magnetic field, this alternating magnetic field enter in roller shell and There generates electric current, and this induced current heats this roller shell.
According to the present invention, the most all known coil arrangements for this purpose can With thering is no ferrimagnet in the inside of roller shell use, but cylindrical coil or multiple each other before and after The cylindrical coil successively arranged is particularly suited for this purpose.
Due to the simple structure of bobbin, present disclosure additionally applies for having up to 1500mm or or even Longer axial length, long especially godet.Diametrically outside, this coil arrangement is also Not restriction, thus overall diameter fully achieve 500mm and more than.
As in principle by known in the art, in the present invention, temperature adjusting can also be by by means of extremely Temperature in a few temperature sensor measurement godet realizes, wherein, and this temperature sensor and use Regulation device in the AC power of regulation and control induction coil layout structure is connected.
It should also be noted that in currently preferred form of implementation, roller shell has been connected with drive shaft The outer side of the godet come is made up of ferromagnetic material.The most additionally advantageously heating hub portion.Simultaneously this Stray magnetic field is stoped to occur in the outside of Galette unit.
