Description

For the packaged ring-type bar of the continuous material that manufactures flat equipment and Method
Technical field
The present invention relates to a kind of apparatus and method for being used to manufacture the packaged ring-type bar of the continuous material of flat. In particular, it is related to a kind of apparatus and method for being used to manufacture aerosol generation object or smoking article or its component.
Background technology
Aerosol generates object or its component (such as filtering plug) typically at least part by such as paper, tobacco or plastic slat Continuous material etc. flat is manufactured.The flat continuous material is subsequently formed into ring-type bar.The ring-type bar is packaged into In wrapping paper.Adhesive is provided to wrapping paper to close wrapping paper and wrapping paper is fixed into ring-type bar.It is attributed to for giving birth to The special material (especially plastic material) filled in and the high production speed for manufacturing these plugs are produced, often displacement is filled in or is packed from it Paper drops.This is especially apparent in a case where:The carriage direction suddenly change of strip-shaped product or semi-finished product, for example, prolong from longitudinal direction The movement for being transverse to this direction is changed into the movement on direction stretched.Unlocked section may be attributed on the first direct of travel it is used Property and remove.This can cause the blocking of production line.It can also cause limitation to speed of production, or negatively affect final strip production The operation of product.
Accordingly, it would be desirable to which a kind of packaged ring-type bar for being used to manufacture the continuous material of flat is in such as smoking The apparatus and method used in the production of the aerosols such as object generation object.In particular, it is necessary to which a kind of be used to manufacture generally The apparatus and method of the improved grappling that its wrapping paper is expected with web of the packaged ring-type bar of flat continuous material.
The content of the invention
There is provided a kind of packaged ring-type bar for being used to manufacture the continuous material of flat according to an aspect of the present invention Equipment.The equipment includes being used for the bar formation unit that the continuous material of flat is shaped as to ring-type bar.It is described to set It is standby also to include being used to provide wrapping paper and the packing device for packing ring-type bar with wrapping paper.There is provided adhesive applicator is used for Wrapping paper is applied adhesive to before packaging ring-type bar.The equipment further comprises that being arranged in bar formation unit upstream uses The corona module of sided corona treatment is carried out in the continuous material to flat.
In corona module, the continuous material of the flat is through sided corona treatment.By sided corona treatment, improve continuous The wetting characteristics of at least side of material.Whereby, compared with material of the identical without sided corona treatment, in a device later or under Swim adhesive preferably wetting continuous material and the distribution above the extension of continuous material respectively that farther place applies.As general When wrapping paper is packaged in around strip continuous material, adhesive is then not only in small finite point but also in the extension area of adhesive The material of bow strip in domain.This improves the grappling that web expects its wrapping paper.Therefore, it can reduce or prevent strip material in wrapping paper In longitudinal direction and swing offset risk.It is therefore possible to prevent strip material being not intended in its wrapping paper or from the generation of its wrapping paper Displacement or loss, or reduce its incidence.This at high production speeds and when use with low relative adhesion material (example Such as paper and plastic material) when it is particularly advantageous.
Adhesive applicator arranged can be used to apply adhesive to wrapping paper with specific pattern and position, preferably The middle body of wrapping paper is applied to, will be such as more fully described below on methods described.Preferably, an equipment is passed through after It is programmed to carry out the method.
Generally disappeared in a few days in addition, being attributed to the effect, sided corona treatment has few permanent shadow to product performance Ring.Few machine rebuilding through handling material also occurs during sided corona treatment.Because sided corona treatment does not need chemical substance, Do not have the remnants of unexpected chemical substance be maintained at be incorporated in the product of the material handled by corona field or on.
Depending on the material for wrapping paper, sided corona treatment can also improve bonding force of the wrapping paper material to its own, especially Its in wrapping paper material also through sided corona treatment in the case of.Therefore, sided corona treatment can also support the shape of the reliable seam of wrapping paper Into.
Because adhesive is usually needed for manufacturing process but is not necessarily needed for final products or desired material, institute Bottom line should be maintained at the amount of adhesive.Via the preferable bonding and distribution of adhesive after the sided corona treatment of strip material, The amount of adhesive may be restricted, and still with the flat with being manufactured in the case of without extra sided corona treatment The packaged ring-type bar of continuous material compares improved grappling.
Sided corona treatment is that the surface for being used for the plastic material (especially) such as polyethylene, polypropylene and polyester foil is modified The electrochemical process known.Sided corona treatment is performed to strengthen wettability of the surface (such as printed liquid).As will be by corona The base material of the material of processing is exposed to the high-voltage discharge occurred between electrode and counterelectrode, and counterelectrode is generally in Earthing potential.By sided corona treatment, the surface tension through handling material is have changed via the ionization for the fluid for surrounding base material. If base material docks counterelectrode, then the side for being only oriented towards electrode of base material is processed under high voltage.Generally, electrode Powered by the high frequency generator with 10 to the frequency between the alternating voltage and 10 and 60kHz 20kV.
According to the one side of the equipment according to the present invention, the electrode of corona module or the shape of counterelectrode correspond to corona mould Surface of the continuous material of flat along its induction element guided in block.In such embodiment, passing through corona While module, continuous material is guided above induction element.Induction element can directly serve as electrode or counterelectrode.It is preferred that Ground, induction element is counterelectrode.Preferably, counterelectrode is electrically isolated from each other.Preferably, counterelectrode is maintained at earthing potential.If big The direct contact guidance element (for example guiding reel) of flat continuous material on body, then the contact guidance element of continuous material Side is without sided corona treatment.In this setting, the side for being only oriented towards electrode of continuous material carries out sided corona treatment.
The use of induction element can further simplify the disposal and conversion of base material during or between production run.So And, corona module may be adapted to the different materials with constant geometrical condition.Preferably, when corona module is to enliven, that is, work as When continuous material carries out sided corona treatment, continuous substrate material continuously and is preferably directed across corona module with constant speed.
