Description
Методът и възелът за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой са приложими за производството на опаковки от ламинатно фолио, по-специално туби, бутилки, кутии и други.The method and assembly for protecting the bare edges of a multilayer laminate film with at least one metal layer are applicable to the manufacture of laminate film packages, in particular tubes, bottles, boxes, and the like.
ПРЕДШЕСТВАЩО СЪСТОЯНИЕ НА ТЕХНИКАТАBACKGROUND OF THE INVENTION
Известни са метод и възел за защита на оголени краища на многослойно ламинатно фолио [ЕР 0152616 А2].A method and a knot for protecting the bare edges of a multilayer laminate film are known [EP 0152616 A2].
Чрез известният метод за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой, срещу избрания един среден слой, чийто оголен срез не трябва да контактува с продуктите, които ще се опаковат в това фолио, се насочва мощен лазерен лъч, който изпарява до зададена дълбочина този слой. Изпареният частично слой може да е от хартия, алуминий и др. Полученият канал се запълва допълнително с безопасен материал или чрез огъване и притискане на външния съседен безопасен слой.The known method of protecting the bare edges of a multilayer laminate film with at least one metal layer against a selected middle layer whose bare section does not have to come into contact with the products to be packed in this film, directs a powerful laser beam that evaporates to a given depth this layer. The partially evaporated layer may be made of paper, aluminum, etc. The resulting duct is additionally filled with safety material or by bending and pressing the outer adjacent safety layer.
Известният възел за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой се състои от лазерен изпарител и запечатваща екстрадираща дюза и/или запечатващ огъвач-притискач.The known knot for protecting the exposed edges of a multilayer laminate film with at least one metal layer consists of a laser evaporator and a sealing extrusion nozzle and / or a sealing bend-presser.
Недостатък на известните метод и възел за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой е, че:A disadvantage of the known method and assembly for protecting the bare edges of a multilayer laminate film with at least one metal layer is that:
- използването на лазер усложнява възела и изисква допълнителни противопожарни защити;- the use of a laser complicates the assembly and requires additional fire protection;
- по време на изпаряването, обработваният слой и неговите съседни слоеве частично изгарят и получените отровни летливи отпадъци остават в работната зона.- during evaporation, the treated layer and its adjacent layers are partially burned and the toxic volatile waste generated remains in the working area.
- поради това при използването на елементи от така обработеното фолио с отровни отпадъци по него се получава контакт с продукта, който се опакова в него, ·· ·· • · · ·· · · което е недопустимо;- therefore, the use of elements of the poisonous waste film treated in this way results in contact with the product which is packed in it, which is inadmissible;
- освен това по същите причини работата на персонала изисква допълнителни защитни облекла и маски;- furthermore, for the same reasons, the work of staff requires additional protective clothing and masks;
- известният метод за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой може да обработва само линейни краища, което ограничава приложението на получените детайли.- the known method of protecting the bare edges of a multilayer laminate film with at least one metal layer can only process linear edges, which limits the application of the details obtained.
ТЕХНИЧЕСКА СЪЩНОСТ НА ИЗОБРЕТЕНИЕТОSUMMARY OF THE INVENTION
Задачата на изобретението е да се създаде опростени метод и възел за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой сIt is an object of the invention to provide a simplified method and assembly for protecting the bare edges of a multilayer laminate film with at least one metal layer with
разширено приложение, безопасни за персонала, с повишено качество на защитата на обработения край, и с възможност да обработва краища с различна топология.an expanded application, safe for staff, with improved quality of machined edge protection, and able to handle edges with different topologies.
Тази задача се решава, като се създава метод за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой, при който заготовка от многослойно ламинатно фолио с поне един метален слой се полага върху работна повърхност. След това върху заготовката едновременно се прилага притискане и нагряване, докато неметалните слоеве на заготовката се разтопяват и в следствие на приложения натиск се изместват върху края, докато среза на металният слой се покрие от разтопените неметални слоеве и те се слеят в едно покритие. След това се прекратява нагряването и се охлажда под натиск, докато слетите слоеве се втвърдят. Тогава се прекратява натискът и заготовката се отстранява от работната повърхност.This problem is solved by creating a method for protecting the bare edges of a multilayer laminate film with at least one metal layer, in which a workpiece of multilayer laminate films with at least one metal layer is applied to a work surface. Then, the workpiece is simultaneously pressed and heated while the non-metallic layers of the workpiece are melted and, as a result of the applied pressure, are shifted to the end, while a slice of the metal layer is covered by the molten non-metallic layers and they merge into a single coating. The heating is then stopped and cooled under pressure until the fused layers have solidified. Then the pressure is stopped and the workpiece is removed from the work surface.
Възможно е в метода за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой, нагряването да се осъществява с високочестотно електромагнитно поле.In the method of protecting the bare edges of a multilayer laminate film with at least one metal layer, the heating can be carried out with a high-frequency electromagnetic field.
Възможно е в метода за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой, изтичането на разтопения материал да се ограничава чрез формоване по времето на изстиването.In the method of protecting the exposed ends of a multilayer laminate film with at least one metal layer, the leakage of the molten material may be limited by molding during cooling.
Създава се и възел за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой, в който има работната повърхност за поставяне на ···· ·· заготовката от многослойно ламинатно фолио с поне един метален слой, чиитоA knot is also created to protect the exposed edges of a multilayer laminate film with at least one metal layer, in which there is a working surface for affixing a multilayer laminate film with at least one metal layer whose
метален слой трябва да се защити. Освен това възелът над работната повърхност има притискащ елемент, който е с нагряващ елемент в него.the metal layer must be protected. In addition, the assembly above the work surface has a clamping element which has a heating element therein.
Възможно е във възела за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой нагряващият елемент да е вградена индукционна намотка.It is possible that the induction coil is embedded in the knot for protecting the bare edges of a multilayer laminate film with at least one metal layer.
Възможно е възелът за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой да има формоващ стопер.It is possible that the knot for protecting the bare edges of a multilayer laminate film with at least one metal layer has a molding stopper.
Предимства на възела са, че може да работи с различна топология на защитавания край, не се получава изгаряне и съответно отделяне на опасни съединения в зоната на защитения слой и не се използват уреди, които създават опасност за персонала.Advantages of the unit are that it can work with different topology of the protected end, does not result in burning and consequently separation of dangerous compounds in the area of the protected layer and does not use devices that create danger for the personnel.

ПРИМЕРНО ИЗПЪЛНЕНИЕ И ДЕЙСТВИЕ НА ИЗОБРЕТЕНИЕТОEXAMPLE IMPLEMENTATION AND ACTION OF THE INVENTION
По-подробно изобретението е пояснено с едно примерно изпълнение на метода и възела за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой, показано на фигурите.The invention is explained in more detail by an exemplary embodiment of the method and assembly for protecting the bare edges of a multilayer laminate film with at least one metal layer shown in the figures.
Метод за защита на оголени краища на многослойно ламинатно фолио с поне един метален слой, при който заготовка 2 от многослойно ламинатно фолио е с ·♦··A method for protecting the bare edges of a multilayer laminate film with at least one metal layer in which a blank 2 of the multilayer laminate film is · ♦ ··
поне един метален слой 3, като тази заготовка 2 се полага върху работна повърхност 1. След това върху заготовката 2 едновременно се прилага притискане и нагряване с притискащия елемент 4, докато неметалните слоеве на заготовката се разтопяват и в следствие на приложения натиск се изместват върху края, докато среза на металният слой се покрие от разтопените неметални слоеве и те се слеят в едно покритие. След това се прекратява нагряването и се охлажда под натиск, докато слетите слоеве се втвърдят. Тогава се прекратява натискът и заготовката 2 се отстранява от работната повърхност. Разтопеният материал може да се ограничава чрез формоващ стопер 7 по времето на изстиването.at least one metal layer 3 is applied to the work surface 1. This workpiece 2 is then pressed and heated simultaneously with the workpiece 2, while the non-metal workpiece layers are melted and displaced at the end by the applied pressure. until a slice of the metal layer is covered by the molten non-metallic layers and they merge into a single coating. The heating is then stopped and cooled under pressure until the fused layers have solidified. The pressure is then stopped and the workpiece 2 is removed from the work surface. The molten material may be limited by a molding stopper 7 during the cooling time.
©Възможно е нагряването на притискащия елемент 4 да става по време на притискането чрез вградената индукционна намотка 6, в която да се подава високочестотен ток (източникът на тока не е показан на фигурите) и създаденото поле да нагрява металния слой 3 на заготовката 2.© It is possible to heat the pressure element 4 during the pressure by means of the built-in induction coil 6, in which a high frequency current is supplied (the current source is not shown in the figures) and the created field heats the metal layer 3 of the workpiece 2.
И в двата случая неметалните слоеве 5 на заготовката 2 се разтопяват и в следствие на приложения натиск се разтичат. От своя страна металният слой 3 не се разтопява и не промяна значително своето положение. По такъв начин срезът на металния слой 3 остава покрит от разтопения материал на неметалните слоеве 5. Следва прекратяване на нагряването и охлаждане под натиск, при което разтопените слоеве 5 се сливат и се втвърдяват.In both cases, the non-metallic layers 5 of the workpiece 2 melt and, as a result of the applied pressure, flow. For its part, the metal layer 3 does not melt and does not significantly change its position. In this way, the slice of the metal layer 3 remains covered by the molten material of the non-metallic layers 5. This is followed by the termination of the heating and the cooling under pressure, whereby the molten layers 5 merge and solidify.
Полученият полуфабрикат - заготовката от многослойно ламинатно фолио с поне един метален слой, се отстранява от възела, или, ако той е пригоден за последващи операции с него (като, например, формоване и др.) може да остане на място за придвижване на следваща позиция (не показани на фигурите).The resulting semi-finished product - the workpiece of multilayer laminate film with at least one metal layer, is removed from the assembly or, if it is adapted for subsequent operations with it (such as molding, etc.), it may remain in place to move to the next position (not shown in the figures).
