Abstract

The invention relates to a device for embossing and/or glazing fine metallic paper, comprising at least a first and a second embossing roll. The flat material can be fed under pressure between said embossing rolls, in order to create a pattern. At least an additional embossing roll (4) is connected downstream of the second embossing roll (3). Said additional embossing roll interacts with the first (2) or preceding (3) embossing roll. The patterned flat material (6) can be fed between these embossing rolls, in order to be embossed again with substantially the same pattern. In complex processing methods, especially under the condition that there is a thin metaled paper, it can avoid using high compressive stress with serious abrasion, and it is advantageous to synchronise the embossing rolls.

Description

Handle the equipment of flat material
The present invention relates to a kind ofly be used to handle the equipment that flat material is particularly useful for film embossing and/or glaze light by claim 1 preamble is described.For example by US-A-5007271 or known this kind equipment of US-A-5598774 of same applicant.Flat material especially refers to these bands or web, and promptly they are covering layer of metal in one side, aluminium normally, and their carrier is made of paper or common fibrous material, or for example refers to the film by plastics, metal or composite system.
Above-mentioned emebosser especially is used for glaze light packaging material in packaging industry, but wherein also coining trademark, coded sequence etc. simultaneously.Here glaze light refers to and adds millimeter on the surface and less than the refined net in the millimeter scope.This type of band or laminar packaging material for example are applied to packing smoking articles, cigarette, food, chocolate, chewing gum etc.
It is suitable that the equipment that preface is mentioned had proved already, if these films of wanting glaze light especially packing film mainly be with aluminium or mainly be that the paper that usefulness is easy to folding line is made.These packaging material for example task when manufacturing the cigarette of bag are will count the cigarette of clear quantity in process of production and seal, so that in the cigarette case of then packing into.
In order to observe the environmental regulations of increasingly stringent, the material of embossing to obtain further development, promptly, these want the object of embossing, especially metallized paper has been strengthened fibrillatable, thereby has been worsened favourable folding line characteristic constantly in the bed thickness that reduces to metallize.
When using mentioned equipment, can observe, in traditional embossing process, strengthened under the Fibrotic situation for the paper of wanting glaze light, the fiber of paper disconnects no longer fully, and after the folding line process, can see so-called memory effect, the result be the part crossed of folding line again towards the direction part back bending of reset condition.Therefore, come adverse influence for the dress tape of the cigarette packaging unit of sealing with new package material or can not carry out sometimes.If the paper of wanting embossing is owing to bad storage loses moisture content, and thereby further improved the toughness of paper fiber, then strengthened above mentioned effect more significantly.Although perhaps can be before folding line or embossing by heat treatment or adopt remedial measures on purpose for the material humidification at this effect, for packaged food, chewing gum, cigarette etc. do like this from hygienic viewpoint to see it is disadvantageous.Otherwise, in some cases advantageously, the paper of embossing is flattened with roller again.
In order still to process this material that is difficult to folding line, the thrust of used knurling rolls is brought up to the thrust when being higher than to pass by the accepted standard material significantly in the file that part will be mentioned in the above.But the result who does like this falls sharply the service life of knurling rolls, and must breaks in production for the work of necessity except the expense of replacement part, has consequently reduced efficient generally and has reduced productive profit thus.
Learn also similarly that with it for the inlet control of quality, the terminal use should very strictly limit the quality tolerance band of the material of paper manufacturers supply.Its reason is that because thickness deviation is excessive, embossing pressure that is to say the thrust of roller on driven roller that match, and must significantly improve again, so that under any circumstance can both realize enough powerful impression.Owing to improved the quantity that quality requirement has limited possible supply of material company greatly, or they must make greater effort in order to produce this paper.
Compare with known prior art, the objective of the invention is the folding line characteristic that improves the quality of embossing and glaze light and improve processed film, meanwhile do not improve embossing pressure and thereby do not increase the wearing and tearing of knurling rolls.This purpose reaches by means of the equipment by claim 1.
By disclosed solution in the claim 1, show unexpectedly, at least another is used for the material knurling rolls of embossing again by connecting in the downstream, not only significantly reduced thrust, for example thrust by half but also has been accomplished obvious the improvement visual signature of embossed material and its folding line characteristic.
Other designs and improvement explanation in the dependent claims by present device.
The embodiment that represents by means of accompanying drawing further specifies the present invention below.Wherein:
First kind of form of implementation signal of Fig. 1 the present invention and perspective view;
Equipment and signal and the profile of wanting the material of embossing that Fig. 2 is shown in Figure 1;
Equipment that Fig. 3 is shown in Figure 1 and partial, detailed view;
Fig. 4 is by second kind of embodiment of equipment with synchronous transmission device of the present invention;
Equipment and the profile of wanting the material of embossing that Fig. 5 is shown in Figure 4;
The equipment that Fig. 6 is shown in Figure 4 and the enlarged detail of tooth; And
The equipment that Fig. 7 is shown in Figure 4 and the enlarged detail of other teeth.
First kind of embodiment of Fig. 1 indication equipment 1, it has pair important components of the present invention, one with second knurling rolls 3 with at first knurling rolls 2 of knurling rolls 4 cooperatings in downstream, wherein first knurling rolls 2 are driven by drive unit 5, and other two rollers 3 and 4, that is the roller that matches, neither be driven also and do not pass through lazy-tongs (for example gear) synchronization with driven roller, but by means of material 6 (see figure 2) transmissions.
As shown in Figure 2, the material 6 of embossing, for example pass through the paper of the sheet metalization of a 0.006mm, vertically, that is in this figure, flow from the top down.
The knurling rolls of representing in Fig. 1 and 2 have smooth surface, can process different structures in order that hint it.A kind of favourable structure be by the tooth of the US-A-5007271 that at first mentions or by earlier disclosed european patent application 98811220.7 through improved design.
When replenishing the embossing again of embossing, importantly all knurling rolls have the similar tooth with same size, so be in symmetrically between four teeth of opposed roll at each tooth of each roller under the basicly stable situation of relative position this.Different decorative patterns is embossed into a total decorative pattern before and after when replenishing embossing.
For the impression of the coded sequence that is called decorative pattern (Muster) below realizing, trade mark etc., remove in the position that requires or shorten tooth.These rags can or only be carved on a roller in this case, driven roller for example, or on different rollers.Rag on the roller that matches is designed to identical or changes, in this case at first more bigger by area than on follow-up one or more rollers that match of decorative pattern on the roller that match, so that obtain profile clearly by means of follow-up roller.
Be used for adopting similar tooth on all cooperative knurling rolls of embossing again, the tooth that is not only applicable to pyramid shape, these teeth are parallel and perpendicular to longitudinal axis and arrange, and are applicable to the tooth of any kind of arranging by variety of way.
In Fig. 1 and 2, represent two match roller 3 and 4 and driven roller 2 engagement, but not necessarily always this situation.Some that it is also contemplated that second or other match roller can be only and first that is that roller engagement that matches of going before.In addition maybe advantageously, establish altogether more than three knurling rolls for some application scenario, they all have similar tooth.In addition, the diameter of each roller can be different with length.Except knurling rolls, can also use soft roller.
The ground supporting of driven roller 2 fixed-site, and at least one freely turns round and supports by the mode of introduction in U.S. Pat-5598784 in two rollers that match.Cause the axis of knurling rolls no matter longitudinally or along compression aspect and/or along material flow direction can be offset thus.This just might adjust knurling rolls, make tooth intermesh exactly and thereby can process to nothing to find fault with, be without rebuke material, meanwhile can not crumple material.In the european patent application of mentioning in front 98811220.7 this point has been described also.
Remaining drive unit of equipment and structural details can be referring to the US-A-5598774 that mentions, in this example the material perpendicular flow.Schematically illustrated supporting arrangement among Fig. 1, that is two supports 7 of two bearings have been housed.Also expression whereby, the supporting of roll shaft can one by one or in groups or jointly be carried out.
By using follow-up roller and reducing thrust, there is no need fully to establish expensive deflection compensation device for knurling rolls again.
Fig. 3 and Fig. 1 are same equipment, and identical part is also represented with same label.Represented a kind of definite tooth among Fig. 3, wherein the position mentioned already in the above of each tooth 8 is designed to the prismoid equally, but the side of cone is not parallel or be not orthogonal to the longitudinal axis of knurling rolls, but can become an angle arbitrarily, for example 45 ° with it.
Being specially adapted to rag by the equipment of Fig. 1 to 3 is on the driven roller 2 and two rollers that match have only tooth not have under the situation of rag.In addition, this equipment preferably be applied to material match at two not crooked or have only seldom under the crooked situation of amount between the roller, unclear to avoid soft edge.
If on the one hand the regulation rag not only built on one of them knurling rolls for example on the driven roller but also built in one or even two rollers that match on, and/or exist paper on the other hand two serious crooked danger between the roller that match, so favourable and what can not exempt from sometimes is to make roller synchronization constantly mutually.In pressing second kind of embodiment of Fig. 4 to 7, the roller 11 and second that matches of the driven rollers 10, first in the equipment 9 matches roller 12 mutually by gear 13,14 and 15 synchronizations.Here as lazy-tongs, other known lazy-tongs comprise electronic component etc. to gear at large.
Embossing exactly under the complicated situation that synchronization allows to mention in the above.Here also be the material of wanting embossing to be carried out precompressed basically, then implement embossing again, so that eliminate the residual stress that also leaves in the material to the full extent by second roller that matches by means of first roller that matches.In this case, embossing is positioned in the precreping as far as possible again.That is to say, matched under the situation on the follow-up roller that matches of also being present on the roller, can process more biggerly than the follow-up roller that matches at first profile that matches on the roller, so that make better profile by area when rag both has been present in first.
The supporting of roll shaft, the roller that matches be on the driven roller or identical among the processing of storing on the roller that is going before and rag and in front that embodiment, but some other possibility of its application also is provided under synchronized situation in addition.Match in the roller one or two all or some can to have with respect to driven roller be opposite rag, that is to say that driven roller has (cloudy) rag of sun, and one or more roller that matches has (cloudy) rag of sun.
Here knurling rolls also needn't have identical diameter and length, but different with first kind of embodiment are, if the diameter of roller is inequality, the diameter of the situation lower roll of realizing by means of gear in synchronization must become ratio of integers mutually so, and length can be unique.
Drawn among Fig. 6 with Fig. 3 in the tooth of identical roller.
Drawn the tooth at quarter with tooth 16 among Fig. 7, they are made up of the angle centrum of band rhombus bottom surface, and their side is parallel with the longitudinal axis of roller or become angle arbitrarily.In addition, tooth also can be a kind of truncated cone.
The same applicant who here refers explicitly to has not earlier illustrated a kind of emebosser in the disclosed european patent application 99810255.2, and wherein one of knurling rolls are included in the stand-by unit at least, and stand-by unit can position be in accordance with regulations packed in the storage rack.
In this equipment that at least three knurling rolls are arranged, roller is single or be located in groups outstanding advantage is arranged in the stand-by unit, because so rationalize effect and environmental protection advantageous particularly to obtaining.
Disclosedly can find out by equipment of the present invention many advantages are arranged by above:
1. fracture best paper fiber and eliminate to the full extent the memory effect of paper of its fair meter. It So can accomplish this point is accurately location because the knurling rolls that front and back are arranged are in operation. Thus Can accomplish, even also can not have in the situation of visual deficiencies again in the very meticulous glaze light time Press the decorative pattern that exists.
