Abstract

The method of thermoplastic sticking of flat elements has the following features: The sticking does not take place in the straight line as it happens when sticking is carried out between rotating rollers of rolling machines (mills); the sticking takes place over the whole area, without having to subject the bonded sandwichto tension. The proposed design of thermoplastic sticking of materials gives rise to an opportunity of forming new types of products closely focused on the final characteristics required. In principle, this is the method of melting-on the whole area of the sticking thermoplastic interlayer of the sandwich formed, starting on the reverse side, in an appropriate time and thermal operting mode. Very important is the use of side stops preventing the greater compression of material than required and the impression of the set sticking "interlayer" into the material, which would impair the strength of the bond. The individual elements of the product (sandwich) are bonded by means of a fusible "interlayer" allover the area. Heat is delivered from the reverse side, and the sticking "interlayer" of a suitable weight is inlaid according to the characteristics of the elements bonded and requirements for the joint strength. The whole technological and operating process is closely connected with time and thermal modes. The input and subsequently output parameters required are attained by side stops of the "press ironer", the height setting of the parameters defines the target thickness of the final product.

Description

Oblast technikyTechnical field

Vynález se týká způsobu termoplastického lepení plochých dílů. S využitím termoplastické mezivrstvy dochází ke spojení vstupujících dílů bez porušení jejich vzhledových i fyzikálních a mechanických vlastností.The invention relates to a method of thermoplastic bonding of flat parts. Using the thermoplastic interlayer, the joining parts are joined without compromising their visual and physical and mechanical properties.

Dosavadní stav technikyBACKGROUND OF THE INVENTION

Doposud užívané postupy pro spojování plochých dílů z tavitelných materiálů v tzv. sendviče využívaly termoplastických vlastností slepovaných dílů, ale samotné spojení probíhalo za pomoci přídavných tavitelných složek vkládaných do struktury spojovaných dílů nebo do místa spoje. Používá se vložení vláken nebo se provádí klasický rubový zátěr na jednu ze slepovaných stran s následným ohřevem a zatížením. Při tomto zpracování dochází vždy k nežádoucímu zhutnění a stlačení vzniklého sendviče. Další nevýhodou dosavadního stavu je ta skutečnost, že spojování probíhá jako spojování dvou nekonečných pásů mezi lisovacími válci, kde finální sendvič je namáhán na tah a tím dochází k jeho další deformaci, tedy k nepravidelnému vlivu na tloušťku výsledného výrobku.Previously used methods for joining flat parts of fusible materials in so-called sandwiches used thermoplastic properties of glued parts, but the joining itself was done by means of additional fusible components inserted into the structure of the parts to be joined or to the place of the connection. Fibers are used or a classic backing is applied to one of the glued sides with subsequent heating and loading. This processing always causes undesirable compaction and compression of the resulting sandwich. A further disadvantage of the prior art is that the joining takes place as the joining of two endless belts between the press rolls, where the final sandwich is subjected to tension and thereby further deformed, i.e., irregularly affecting the thickness of the resulting product.

Podstata technického řešeníThe essence of the technical solution

Uvedené nedostatky stávajícího stavu techniky se odstraní způsobem termoplastického lepení plochých dílů podle vynálezu, jehož podstata spočívá v tom, že lepení neprobíhá v/ omezené stykové přímce vytvořené dotykem povrchů přiléhajících válců jako je tomu u lepení mezi rotačními válci válcovacích strojů (stolic), ale celoplošně bez tahového namáhání lepeného sendviče.These drawbacks of the prior art are eliminated by the method of thermoplastic gluing of flat parts according to the invention, which consists in that the gluing does not take place in a limited contact line formed by contacting the surfaces of adjacent rollers as in gluing between rotating rollers without tensile loading of the glued sandwich.

Navrhované řešení termoplastického spojování materiálů dává možnost vzniku nových typů výrobků úzce specifikovaných na požadované finální vlastnosti. Principiálně se jedná o celoplošný způsob natavení lepicí termoplastické mezivrstvy vzniklého sendviče od rubové strany v odpovídajícím časovém a tepelném pracovním režimu. Velmi důležitý faktor je zde také použití bočních zarážek, které zabraňují většímu stlačení materiálu než je požadováno a zároveň vtlačení nastavené lepící mezivrstvy do materiálu, a tím také snížení pevnosti spoje.The proposed solution of thermoplastic joining of materials gives the possibility to create new types of products closely specified for the required final properties. In principle, it is a full-area method of melting the adhesive thermoplastic intermediate layer of the resulting sandwich from the reverse side in the corresponding time and thermal operating mode. A very important factor here is also the use of lateral stops which prevent the material from being compressed more than desired and at the same time pushing the adjusted adhesive interlayer into the material, thereby reducing the bond strength.

Jednotlivé části výrobku (sendviče) jsou spojovány tavitelnou mezivrstvou v celé ploše. K předání tepla dochází od rubové strany a podle charakteru spojovaných částí a požadavků na pevnost spoje je vkládána lepící mezivrstva o odpovídající hmotnosti. Celý technologickopracovní proces je úzce spjat s časovým a tepelným režimem. Zajištění vstupních a následně výstupních parametrů je řešeno bočními zarážkami Žehlícího lisu, které svým výškovým nastavením vymezují výslednou tloušťku finálního výrobku.The individual parts of the product (sandwiches) are joined by a fusible interlayer over the entire surface. Heat transfer takes place from the reverse side and, depending on the nature of the parts to be joined and the strength requirements of the joint, an adhesive intermediate layer of appropriate weight is inserted. The whole technological process is closely related to the time and thermal regime. Ensuring the input and output parameters is solved by the side stops of the Ironing Press, which by their height adjustment define the final thickness of the final product.

Velmi důležitý a také kritický moment celého termoplastického lepem je následné clilazent slepovaného spoje. Tato část technologického uzlu je řešena zařazením chladícího a kalibračního zařízení speciálně k tomuto účelu zkonstruovanému.A very important and also critical moment of the whole thermoplastic adhesive is the subsequent clilazent of the glued joint. This part of the technological node is solved by the inclusion of cooling and calibration equipment specially designed for this purpose.

Tepelně slepený materiál je v celé ploše vložen do tohoto zařízení u kterého jsou rovněž zabudovány stavitelné boční zarážky. Slepovaný materiál je pak oboustranně chlazen protékajícím médiem (vodou).The thermally bonded material is fully embedded in this apparatus, in which also adjustable lateral stops are incorporated. The material to be bonded is then cooled on both sides by the flowing medium (water).

Navrhovaný způsob lépe řeší fixaci tepelného spoje v porovnání s průběžným tepelným lepením (rotační válce), u kterého dochází vždy k částečnému posunu slepovaných složek (materiálů).The proposed method better solves the fixation of the thermal joint in comparison with the continuous thermal bonding (rotary rollers), in which there is always a partial shift of the glued components (materials).
