Description

Vertikalni hadicovy balici stroj
Oblast techniky
Vynalez se tÿka nového konstrukcniho reseni a prostorového uspofadani vybranÿch funkcnich celkù na vertikalnich hadicovÿch balicich strojich, zejména kontinualnich, které slouzi pro tvarovani, plneni a uzavirani rùznÿch typù hadicovÿch sackù. Reseni podle vynalezu vÿrazne usnadnuje myti a sanitaci stroje.
Dosavadni stav techniky
Kontinualni vertikalni hadicové balici stroje slouzi ke tvarovani, plneni a uzavirani hadicovÿch sackù. Strojem kontinualne prochazi obalova folie - v oblasti jejiho tvarovani do foliové hadice, jejiho plneni a jejiho uzavirani ve vertikalnim smeru. Pohyb folie zabezpecuji posuvové elementy - femeny nebo kola. Kontinualnimu pohybu obalové folie se museji pfizpùsobit i nekteré prvky stroje, které na ni pùsobi. Jedna se zejména pficné svafovaci celisti a tvarovaci nastroje slouzici ke skladani dna sackù. Ty vykonavaji v oblasti tvorby pficnÿch svarù a sklâdâni dna sackù soubezne vratnÿ vertikalni pohyb podél kontinualne se pohybujici foliové hadice a zaroven i horizontalni pohyb k sobe a od sebe.
U beznÿch kontinualnich vertikalnich hadicovÿch balicich strojù jsou pohony vsech techto pohybù ulozeny v jedné spolecné mechanické skfini. Pohyby vetsiny prvkù pùsobicich na folii se nechaji z této spolecné mechanické skfine vyvést pomoci rotacnich hfideli nebo posuvnÿch tyci, tzn. Z hygienického hlediska bez problémù. Vyvedeni vertikalniho pohybu pficnÿch svafovacich celisti ze spolecné mechanické skfine je vsak z hygienického hlediska velkÿ problém. Skrz celni desku spolecné mechanické skfine museji bÿt vytvofeny drazky do prostoru tvorby pficnÿch svarù, zpravidla tfi az pet, kterÿmi prochazeji tyce, na kterÿch jsou namontovany pficné svafovaci celisti. Drazky maji délku fadove ve stovkach mm a sifku fadove v desitkach mm. Hygienicky uspokojivé zpùsoby jejich zakryti nejsou znamy. Nasledkem toho dochazi ke znecisteni vnitfniho prostoru spolecné mechanické skfine prachem a/nebo balenÿm sypkÿm materialem. Vzhledem k clenitosti a choulostivosti zafizeni uvnitf spolecné mechanické skfine je jejich dostatecné cisteni znacne problematické.
Obecne jsou mechanismy vertikalnich hadicovÿch balicich strojù velmi clenité, a to i ty, které jsou umisteny v oblastech, kde hrozi jejich kontaminace balenÿmi produkty. Jejich cisteni z dùvodù hygienickÿch, nebo napf. z dùvodù odstraneni alergenù, je znacne pracné.
Uvedené nedostatky odstranuje feseni podle vynalezu.
Podstata vynalezu
Podstatou vynalezu je konstrukce vertikalniho hadicového baliciho stroje pro tvarovani, plneni a uzavirani hadicovÿch sackù. Stroj obsahuje zafizeni pro odvijeni ploché obalové folie, typicky z role. Stroj dale obsahuje plnici trubku, ktera je uspofadana (ve smeru pohybu odvinuté folie) za zafizenim pro odvijeni ploché obalové folie. Na plnici trubce je uspofadan tvarovaci limec pro formovani odvinuté ploché obalové folie do tvaru podélne neuzavfené foliové hadice. Pod tvarovacim limcem je na plnici trubce dale uspofadana podélna uzaviraci celist pro podélné uzavfeni foliové hadice. Uzavfenim se mysli svafeni pfekrÿvajiciho se materialu po vytvofeni podélne neuzavfené foliové hadice. Tim vznikne (uzavfena) foliova hadice, ktera mùze bÿt dale delena pficnÿmi svary a plnena zbozim. Dale mùze bÿt uzita jedna nebo vice podélnÿch hranovÿch celisti pro fixaci podélnÿch vÿztuznÿch hran. Podélné celisti (uzaviraci i hranové) mohou bÿt pevné
- 1 CZ 2023 - 40 A3 nebo vertikalne pohyblivé. Vsechny podélné celisti vytvareji svary, které jsou rovnobezné s podélnou osou plnici trubky, resp. foliové hadice.
Stroj dale obsahuje zarizeni posuvu foliové hadice po plnici trubce od tvarovaciho limce k podélnÿm uzaviracim a hranovÿm celistem a k pricnÿm svarovacim celistem, které jsou usporadané pod plnici trubkou. Pricné svarovaci celisti jsou usporadany pro tvorbu pricnÿch svarù, které uzaviraji a oddeluji jednotlivé hadicové sacky od foliové hadice.
Pricné svarovaci celisti jsou vÿstupnimi tycemi propojeny s mechanismem horizontalniho pohybu pricnÿch svarovacich celisti. Soucasti mechanismu horizontalniho pohybu pricnÿch svarovacich celisti je nejméne jedno vedeni vertikalniho pohybu pricnÿch svarovacich celisti. Pricné svarovaci celisti jsou timto vedenim spolecne s mechanismem horizontalniho pohybu pricnÿch svarovacich celisti vertikalne pohyblivé po nejméne jedné vodici tyci. Vodici tyc nebo tyce jsou pevne spojené s ramem. Mechanismus horizontalniho pohybu pricnÿch svarovacich celisti je usporadan ve vertikalne pohyblivé mechanické skrini. Vertikalne pohybliva mechanicka skrin je s mechanismem horizontalniho pohybu pricnÿch svarovacich celisti pevne spojena. To v tomto pripade zejména znamena, ze nejsou vùci sobe vertikalne pohyblivé.

Jedna se o horni mechanickou skrin, ktera je pevne spojena s ramem stroje, a spodni mechanickou skrin, ktera je vùci horni mechanické skrini i vùci ramu stroje vertikalne pohybliva. Tyto skrine obsahuj i vetsinu mechanismù stroj e a maj i jednoduché a hladké vnej si tvary, takze j sou snadno cistitelné.
Horni mechanicka skrin obsahuje vsechny prvky a pohony jako pùvodni mechanicka skrin dle stavu techniky, s vÿjimkou mechanismu horizontalniho pohybu pricnÿch svarovacich celisti a pripadne i pohonu tvarovacich nastrojù pro skladani dna sackù. Mezi obsazené prvky spada pohon zarizeni posuvu foliové hadice, dale pak zejména rùzné mechanické, pneumatické a elektrické prvky pro rizeni a vykonâvâni funkce stroje. Zejména se mùze jednat o pohon vertikalniho pohybu mechanismu horizontalniho pohybu pricnÿch svarovacich celisti, vÿvevu, pneumatické ventily, pohon vertikalniho a/nebo horizontalniho pohybu podélnÿch celisti apod. Spodni, vertikalne pohybliva mechanicka skrin, obsahuje mechanismus horizontalniho pohybu pricnÿch svarovacich celisti a pripadne i pohon tvarovacich nastrojù pro skladani dna sackù. Lze uvazovat i provedeni, ve kterém bude pohon vertikalniho pohybu mechanismu horizontalniho pohybu pricnÿch svarovacich celisti usporadanÿ ve spodni mechanické skrini.
