Vynález aa týká plniacej hlavy na dóvkovanie tekutých médii, najmB pre zariedenia no utrlobrenie skloněných obalov,The invention aa relates to a filling head for the addition of liquid media, in particular to a device for tearing off inclined packages,

U doteraz známého zariadenia na etriebrenle aklenaných obalov, napr. vložiek do termoizolačných fliaš pozostáva plniaca hlava plnlacej jednotky z posúvača ukončeného nllcullo, lín |( 11 ? e ΓI Mil , |.

Plniaca ihla Je uchytená v Jednoduchou) držiaku a vnútorný prieator plniacej hlavy Je uteuiiený toonincou rúrkou.The filling needle is held in a simple holder and the internal preator of the filling head is cleaned by a toonine tube.

Nevýhody doteraz použivanej plniacej hlavy plnlacej Jednotky apočivajú v tom, že spStné ventily zabezpečujúce dávkovanle tekutých médii boli umiestnená mimo plnlacej hlavy, čim dochádzalo k hromadeniu tekutých médii na trase od epBtných ventilov k plniJLcej hlavě a k vzájomnému miešaniu a znehodnocovaniu týchto médii. Calšou nevýhodou plniacej hlavy je značná znečisTovanie pracovného prostredia jednak rozprašováním hmloviny zapříčiněné netěsným spojením čerpacej rúrky a púzdra, jednak netesnoslaml krytovania plniacej jednotky. Toto krytovanle zároveň aj zvyšuje hmotnos? celého zariadenia. Nevýhodou je tiež velká dlžka plniacej ihly, čo často vedie k jej zlomeniu a znehodnoteniu. Komplikovaná a zdlhavá je tiež výměna poškodenej plniacej ihly za novC. Celá konštrukcia plniacej hlavy je zložitá a pozostáva z velkého počtu súčiastok. Nevýhodou doteraz použivanej plniacej hlavy je aj elektrické blokovanie dávkovania tekutých médií pričom dochádza k častým poruchám z dovodu nespolehlivosti elektromagnetických snímačov a zložitého riadiaceho systému. Nevýhodou je tiež vytekanie dávkovanej tekutiny do okolitého priestoru, pretože aj v případe prasknutla skleněného obalu zostáva zapnutý snímač indikujúcl pritomnosT skleněného obalu.Disadvantages of the filling head of the filling unit used hitherto are that the check valves securing the dosing of the liquid media have been placed outside the filling head, thereby accumulating the liquid media on the way from the pressure valves to the filling head and mixing and deteriorating these media. A calmer disadvantage of the filling head is the considerable contamination of the working environment, both by spraying the nebula caused by the leaking connection of the pump tube and the housing and, on the other hand, by leaking the cover of the filling unit. This cover also increases weight? of the entire device. A disadvantage is also the large length of the filling needle, which often leads to its breakage and deterioration. Replacing a damaged filler needle with novC is also complicated and lengthy. The construction of the filling head is complex and consists of a large number of components. A disadvantage of the filling head used hitherto is also the electrical blocking of the liquid medium dosing, with frequent failures due to the unreliability of the electromagnetic sensors and the complex control system. A drawback is also the leakage of the dosed liquid into the surrounding space, since even in the case of a glass container rupture, the sensor indicating the presence of the glass container remains on.

Vyššie uvedená nevýhody odstraňuje a technický problém rieši plniaca hlava na dávkovonio tekutých médii podlo tohoto vynálezu, ktorého podstatou je, že duté válcové teleso je na jednom konci opatřené posuvné uloženým posúvačom a Jeho druhý koniec je pevne spojený s deleným držiakom, v ktorého prednej časti je posuvné uchytený dutý držiak plnlacej ihly, ktorej hrot korešponduje s púzdrom atrediaceho kužela poaúvača. V zadnej časti děleného držiaka je osadený najmenej jeden epStný ventil, ktorý je cez plniaci kanál připojený na dutý držiak plnlacej ihly. Duté válcové teleso je po celej dlžke opatřené obvodovým kanálom vyúsfujúcim najmenej do jednoho výustného kanála.The above-mentioned disadvantages are overcome and a technical problem is solved by the filling head for the liquid-medium dosing device according to the invention, which is characterized in that the hollow cylindrical body is provided with a sliding slider at one end and its other end firmly connected to a split holder in its front part a slidable hollow filling needle holder, the tip of which corresponds to the casing of the slip-on cone. At least one epistle valve is mounted in the rear part of the split holder, which is connected to the hollow filling needle holder via a feed channel. The hollow cylindrical body is provided with a circumferential channel extending all the way into at least one outlet channel.

Dutý držiak plniacej ihly je s výhodou opatřený mechanickým spStným ventilom.The hollow filling needle holder is preferably provided with a mechanical check valve.

Výhody riešenia podle vynálezu spočivajú hlavně v uloženi epBtných ventilov priamo do plniacej hlavy, čim ea zjednoduší dávkovanle plniacich tekutých médii do plniacej ihly a zabráni sa vzájomnému miešaniu médii a ich znehodnocovaniu, Vodoteanou konštrukciou plniacej hlavy a podtlakovým odsáváním tekutých médii ea zabráni znečišfovaniu pracovného prostredia a odpadne poměrně zložitá konštrukcia vodotěsného krytovanla celej plniacej jednotky, čim sa podstatné zniži aj Jej hmotnosf. K íalšim výhodám patři skrátenie plniacej ihly, Čim sa zvýši jej tuhosf a v dSsledku toho tiež Jej životnosf. Delený držiak umožňuje rýchlu výměnu poškodenej plniacej ihly a tak skrátenie nevýrobných časov zariadenia. Mechanický spatný ventil nahrádza zložltý riadiaci systém, elektromagnetické snímače a solenoidové ventily, ktoré blokovali dóvkovanie tekutých médii.Advantages of the solution according to the invention consist mainly in placing epiteal valves directly into the filling head, thereby simplifying the dosing of filling liquid media into the filling needle and avoiding mutual mixing and deterioration of the media, the relatively complicated construction of the watertight covering of the entire filling unit is eliminated, thereby substantially reducing its weight. Other advantages include shortening the filling needle, thereby increasing its stiffness and, consequently, its service life. The split holder enables quick replacement of the damaged filling needle and thus shortens the non-production times of the device. The mechanical check valve replaces the sophisticated control system, solenoid sensors and solenoid valves that have blocked the addition of liquid media.

Claims

The filling head is pushed to the pump tube 16 of the glass container 17, e.g. thermal insulating inserts. The centering cone 3 of the pusher 2 centers the pumping tube 16 and when it reaches the housing 4a and the pusher 2 begins to slide inside the hollow cylindrical body 11. The tip 6 of the filling needle 8 is inserted into the pump tube 16. The slide 2 strikes the hollow holder 10 and opens the mechanical check valve 10. Through one of the check valves 11, the respective filling channel 12 and the mechanical backflow 18 flow the liquid medium into the hollow holder 10. through the tip 9 of the filling needle 8 fills the encapsulated envelope 17. On flushing, the liquid medium is discharged through the air, which flows through the 3 other check valve 11 and the open mechanical pressure valve 18 into the filling needle 0, leaving the liquid medium through the pump tube 16; The pusher 6 into the peripheral duct 13 from where it is sucked through the discharge ducts 14 into the collecting vessel (see FIG. not shown /. After the liquid medium has been dispensed or withdrawn and the filling head is brought back to the original position by the hydroelectric device (FIG. 5), the glass tube 17 is released from the slider 2. By reversing the central spring 15, the slider 2 returns to the upper return position. the filling needle spring 20 returns the filling needle 8 to its initial position and automatically closes the mechanical check valve 18 by actuating the spring 19 of the mechanical check valve 18 and can repeat the entire dosing cycle e.

If the glass container 17 is not located opposite the filling head, or if the glass container 17 ruptures as the tip of the filling needle 6 slides into the lance 16, the mechanical check valve 18 blocks the liquid medium supply.

The filling head is designed especially for dispensing silver solutions and their rinsing from thermo-insulating inserts. Its design makes it possible to fully automate the silvering process.
