Description
Vynález sa týká integrovanej linky na smaltovanie plochých výrobkov práškováním v elektrickom poli, pozostávajúce]' z aspoň jednej elektrostatickej nanášacej kabiny s príslušenstvom, cez ktorú je vedený priebežný dopravník.The invention relates to an integrated electric field powder enamelling line consisting of at least one electrostatic coating booth with accessories through which a continuous conveyor is guided.
Smaltovanie výrobkov, ktoré z híadiska charakteristiky tvaru sú označované ako ploché, sia podlá známého stavu techniky uskutiočňuje v dvoch samostatných operáciách. Povrchovo predupravené dielce sa na samostatnej linke nanášajú metódon práškovamla v elektrickom poli tým, že sú zavesené na priebežný, například podvesný dopravník a přechodem cez nainášaciu kabinu sa automaticky alebo ručně vytvoří požadovaná vrstva prášku smaltu. Podvesný dopravník je nekonečný a výrobky po přechode cez nanášaciu kabinu sú prevešiavané na dopravník vypalovacej pece. Vzhladom na vlastnosti nanesenej vrstvy prásku smaltu, ktorá po otrasoch a kontaktoch s akýmkolvek materiálom sa porušuje, operécia prekladaňia je zdrojem častých chýb výrobku.The enamelling of products which, in terms of shape characteristics, are described as flat, according to the prior art, is carried out in two separate operations. The surface pretreated parts are applied on a separate line by a method of powders in an electric field by being suspended on a continuous, for example overhead conveyor, and by passing through a booth to the desired layer of enamel powder automatically or manually. The overhead conveyor is endless and the products are transferred to the kiln conveyor after passing through the application booth. Due to the properties of the applied enamel powder layer, which is damaged after shocks and contacts with any material, the folding operation is a source of frequent product defects.
Uvedené nevýhody odstraňuje integrovaná linka na smaltovanie plochých výrobkov podlá vynálezu, ktorého podstata spočívá v tom, že< v elektrostatickej oanášacej kabině, prepojenej pomocou priebežného dopravníka s vypalovacou perou je vo smere dráhy dopravníka vytvořený ochranný tunel unášačov tohoto dopravníka, ktoré unášače sú opatřené dvojstrannými závěsnými hákmi, ktorých hroty či břity sú usporiadané v zrkadtavooi obraze voči zvislej centrálnej rovině.The above-mentioned disadvantages are overcome by the integrated flat enameling line according to the invention, which consists in the fact that in the electrostatic booth interconnected by means of a continuous conveyor with a firing tongue, a protective tunnel of carriers of this conveyor is formed in the direction of the conveyor. hooks whose tips or blades are arranged in a mirror image relative to a vertical central plane.
Výhoda vynálezu vyplývá z toho, že výrobky sú zavěšované na integrovaný priebežný dopravník, ktorý je spoločný pre operáciu nanášania a vypalovamia, a to takým sposobom, ktorý neruší proces vytvárania rovnomernej vrstvy prášku smaltu po celej ploché funkčnej časti výrobku. Tým sa odstraňuje závažný zdroj nepodarfcovosti výrobkov, ktoré na priebežnom dopravníku po nanesení vrstvy prášku smaltu kontinuálně pokračujú do vypalovacej pece bez akejkolvek mianipulácie.The advantage of the invention is that the articles are suspended on an integrated continuous conveyor, which is common to the deposition and baking operation, in a manner that does not interfere with the process of forming an even layer of enamel powder throughout the flat functional portion of the article. This removes a significant source of non-gargling of the articles which, on the continuous conveyor, after the application of the enamel powder layer, continuously proceed to the kiln without any mianipulation.
Príklad vyhotovenia integrovanej linky podlá vynálezu je znázorněný na výkresoch, na ktorých ob,r. 1 představuje schematický nárysný pohlad na integrovanú linku, obr, 2 schematický bokorysný rez kabiny s priebežným dopravníkomi, obr. 4, 5 schematický bokorysný pohlad na dve rozino vyhotovenia závěsných hákov, obr. 6 detail „A“ z obr. 5 a obr. 7 představuje hrot závěsného háku z obr. 6 v nárysnom pohlade.An exemplary embodiment of an integrated line according to the invention is shown in the drawings, in which FIG. 1 is a schematic elevational view of an integrated line; FIG. 2 is a schematic side sectional view of a cab with continuous conveyors; FIG. 4, 5 is a schematic side view of two side elevations of the suspension hooks; FIG. 6 shows the detail "A" of FIG. 5 and FIG. 7 shows the tip of the hook of FIG. 6 in a front view.
Integrovaná linka pozostáva z dvoch elektrostatických nanášacích kabin 1 s příslušenstvům, přepojených pomocou priebežného dopravníka 2 s vypalovacou pečou 3. V elektrostatickej nanášacej kabině 1 je v smere dráhy dopravníka 2 vytvořený ochranný tunel 4 unášačov 5 tvoriacich súčasť dopravníka 1. Na dolný koniec týchto unášačov 5 sú prostredníctvom lišty B zavesené dvojstranné závěsné háky 7, a to tak, že jednotlivým článkom dopravné] reťaze sú priradené unášače 5 a každé dva unášače 5 sú přepojené líštou 6, ná ktorej sú umiestnené za sebou dva dvojstranné závěsné háky 7. Hroty 8 závěsných hákov 7 sú usporiadané v zrkadlo;’ :m obraze voči zvislej centrálnej rovině 9, preloženej dráhou dopravníka 2 a to tak, že vyčnievajú od tejto centrálnej roviny smerom von (obr. 4), alebo. ležia v rovinách 10 rovnoběžných, s centráinou rovinou 9.An integrated line consists of two electrostatic coating booths 1 with accessories, connected by a continuous conveyor 2 with a baking oven 3. In the electrostatic coating booth 1, a protective tunnel 4 of grippers 5 forming part of the conveyor 1 is formed downstream of the conveyor 2. the two-sided suspension hooks 7 are suspended by means of the bar B, so that the individual links of the conveyor chain are assigned to the grippers 5 and each two grippers 5 are connected by a bar 6, on which two two-sided suspension hooks 7 are placed. 7 are arranged in a mirror image relative to the vertical central plane 9, intersected by the path of the conveyor 2, so that they protrude outwards from this central plane (FIG. 4); they lie in planes 10 parallel, with centrine plane 9.
Pri prevádzke integrovanej linky sú unášačo 5 záveisené na dopravnej reťazí, chráněné před nanesením prášku tým, že sú v ochrannom tuneli 4, v ktorom je okrem tohio voči vnútornému priestoru kabiny 1 úderný přetlak. Dopravované ploché dielce 11 sú na koncoch závěsných hákov 7 uchytené tak, že nerušia proces elektrostatického raanášania. Tieto konce závěsných hákov 7, najmá ich hroty 8 sú vystavené nanášaniu prášku, avšak po niekolkonásobnom opakovaní celého technologického cyklu možno z nich smailtovú škrupinu poměrně 1'ahko oklepať. Výhodou priebežného dopravníka, na ktorom počas celého technologického cyklu, netřeba prevešiavať závěsy je to, že nedochádza k opádávaniu naneseného prášku.In the operation of the integrated line, the carrier 5 is hinged to the conveyor chain, protected from powder deposition by being in a protective tunnel 4, in which, in addition to this, there is an overpressure against the interior of the cab 1. The conveyed flat parts 11 are fastened at the ends of the suspension hooks 7 so that they do not interfere with the electrostatic shredding process. These ends of the suspension hooks 7, in particular their tips 8, are subjected to powder deposition, but after several repetitions of the entire process cycle, the enamel shell can be easily knocked out of them. The advantage of a continuous conveyor, on which during the whole technological cycle, there is no need to rewind the curtains, is that there is no falling of the applied powder.
