Prednostno se kot material za izdelavo drsnega profila uporabi nerjaveče jeklo, ki ima zelo majhno obrabo. Izboljšano drsno vodilo torej predvsem omogoča manjšo tvorbo neželenih delcev zaradi obrabe koleščkov, obenem pa omogoča večji odmik vratnega krila od drsnega vodila,kar posledično pomeni več prostora in lažji dostop za samo čiščenje, kar je ena od ključnih stvari pri vzdrževanju vrat.The present invention belongs to the field of doors and their accessories, more specifically, the invention belongs to the field of sliding doors for clean rooms. The invention relates to sliding doors for use in clean rooms. The sliding door according to the invention includes a door frame in which at least one door leaf is fixed, which is slidably movable on a sliding guide with the help of at least one movably mounted trolley with wheels, whereby the mobility of the door leaf is provided by a drive unit with a motor. The essence of the invention is that the tubular sliding guide of the door is oval-shaped, or the cross-section of the guide is oval-shaped, which increases the bearing surface of the wheels that ensure the movement of the door leaf. As a result, friction and thus wear on the wheels is reduced, which means that less particles fall off them. Stainless steel, which has very little wear, is preferably used as the material for the production of the sliding profile. The improved sliding guide therefore primarily allows for less formation of unwanted particles due to the wear of the wheels, and at the same time allows for a greater distance of the door leaf from the sliding guide, which in turn means more space and easier access for cleaning itself, which is one of the key things in door maintenance.

Drsna vrata za čiste prostoreSliding doors for clean rooms

Področje tehnikeThe field of technology

Pričujoči izum spada na področje vrat ter dodatkov zanje, natančneje spada izum na področje drsnih vrat za čiste prostore. Izum se nanaša na drsna vrata za uporabo v čistih prostorih.The present invention belongs to the field of doors and their accessories, more specifically, the invention belongs to the field of sliding doors for clean rooms. The invention relates to sliding doors for use in clean rooms.

Ozadje izuma in tehnični problemBackground of the Invention and Technical Problem

Čisti prostor je zaprt prostor, v katerem je nadzorovano število delcev v zraku, temperatura in relativna vlaga zraka, pretok zraka znotraj prostora, razlika pritiska med čistim prostorom in zunanjim okoljem ter mikrobiološka obremenitev prostora. Njihova razdelitev po ISO standardih poteka glede na število delcev v kubičnem metru. V zunanjem zraku v tipičnem urbanem okolju je približno 35000000 delcev v vsakem kubičnem metru, pri čemer so delci velikosti vsaj 0,5 pm kar ustreza ISO 9 čistemu prostoru. Nasprotno, ISO 1 čisti prostor ne dovoli nobenih delcev večjih od 0,5 pm in le 12 delcev na kubični meter, ki so veliki 0,3 pm in manjši. Čisti prostori se običajno uporabljajo v posebnih industrijskih proizvajalnih obratih ali v znanstveno-raziskovalnih ustanovah, kjer je čistost prostora še posebej pomembna. Predvsem so pogosti pri proizvodnji farmacevtskih izdelkov, integriranih vezij, LCD, OLED in mikroLED zaslonov in podobnih izdelkov.A clean room is a closed space in which the number of particles in the air, the temperature and relative humidity of the air, the air flow inside the room, the pressure difference between the clean room and the outside environment, and the microbiological load of the room are controlled. Their division according to ISO standards takes place according to the number of particles in a cubic meter. Ambient air in a typical urban environment contains approximately 35,000,000 particles in every cubic meter, with particles of at least 0.5 pm in size, corresponding to an ISO 9 clean room. In contrast, an ISO 1 cleanroom allows no particles larger than 0.5 pm and only 12 particles per cubic meter that are 0.3 pm and smaller. Clean rooms are usually used in special industrial production plants or in scientific research institutions, where the cleanliness of the room is particularly important. They are especially common in the production of pharmaceutical products, integrated circuits, LCD, OLED and microLED displays and similar products.

Zaradi takšnih zahtev po čistosti prostora, je torej pomembno kakšni konstrukcijski materiali se uporabijo za izdelavo čistih sob, kot tudi kako se ti prostori čistijo in vzdržujejo. Vrata so meja med čistim prostorom in zunanjostjo, kar pomeni, da so ključni element, ki preprečuje vdor delcev in drugih umazanij, ki jih večinoma prinašajo ljudje, bodisi ob vstopu, bodisi ob čiščenju ter vzdrževanju prostorov. Osnovno vodilo za vse elemente, kateri so sestavni del čistih prostorov je, da:Because of such requirements for the cleanliness of the room, it is therefore important what construction materials are used to create clean rooms, as well as how these rooms are cleaned and maintained. The door is the border between the clean room and the outside, which means that it is a key element that prevents the ingress of particles and other dirt, which are mostly brought by people, either when entering, or when cleaning and maintaining the premises. The basic guideline for all elements that are an integral part of clean rooms is that:

- ustrezajo vsem GMP standardom,- meet all GMP standards,

- je njihovo čiščenje in vzdrževanje čim lažje ter je v največji meri omogočeno vzdrževanje brez poseganja v sam čisti prostor.- their cleaning and maintenance is as easy as possible and maintenance is possible to the greatest extent possible without interfering with the clean room itself.

Na tržišču obstaja nekaj drsnih vrat z nizko prepustnostjo zraka, ki se uporabljajo v čistih prostorih, ter so po večini sestavljena iz zelo podobnih osnovnih elementov, kot so vratno krilo, okvir vrat, tesnilo, drsno vodilo, pogon in avtomatika. Poleg osnovnih delov so pomembni tudi prekrivna maska, ki prekrije drsno vodilo, koleščki, s katerimi se zagotavlja premik krila po drsnem vodilu, ter talno vodilo, ki preprečuje nihanje vratnega krila.There are a number of low air permeability sliding doors on the market that are used in clean rooms, and most of them consist of very similar basic elements, such as door leaf, door frame, seal, sliding guide, drive and automation. In addition to the basic parts, the cover mask that covers the sliding guide, the wheels that ensure the movement of the sash along the sliding guide, and the floor guide that prevents the swinging of the door leaf are also important.

Problem obstoječih drsnih vrat za čiste prostore je drsno vodilo, izbrani materiali ter komponente, ki so neposredno povezane z le-tem, to so koleščki, pokrivna maska, pozicija motorja in avtomatizacije, talno vodilo in zaščita samih vrat, vratno krilo). Drsno vodilo je namreč vlečen profil z ustreznimi utori, po katerem se preko koleščkov premika vratno krilo. Ker je profil oster, posledično prihaja do trenja in večje obrabe koleščkov ter posledično ustvarjanja nezaželenih delcev, ki potem prosto padajo v čisti prostor. Prekrivna maska, ki prekriva drsno vodilo, ne preprečuje padanja delcev v čisti prostor. Dodatni problem kontaminacije čistega prostora lahko predstavljajo tudi drugi elementi vrat, ki niso neposredno vezani na koleščke potrebne za premikanje drsnih vrat. Talno vodilo oziroma usmerjevalnik, ki je nameščen in fiksiran v sama tla, se namreč lahko poškoduje in s tem izruva iz podlage, kar lahko pripelje do kontaminacije prostora. Iz vidika vzdrževanja je problematična namestitev pogona in avtomatizacije, ki se nahajata ob drsnem vodilu, ob okvari pa se mora vzdrževanje opraviti s posegom v čisti prostor. Nenazadnje pa je problematično tudi čiščenje, saj se na primer vratno krilo lahko očisti le ob demontaži vrat, kar pomeni, da bo čisti prostor kontaminiran ob demontaži in naknadnem čiščenju.The problem with existing sliding doors for clean rooms is the sliding guide, the selected materials and the components that are directly connected to it, i.e. the castors, the cover mask, the position of the motor and automation, the floor guide and the protection of the door itself, the door leaf). The sliding guide is a drawn profile with appropriate grooves along which the door leaf moves via castors. Because the profile is sharp, this results in friction and increased wear of the wheels and, as a result, the creation of unwanted particles, which then fall freely into the clean area. The cover mask that covers the sliding guide does not prevent particles from falling into the clean room. An additional problem of contamination of the clean room can also be presented by other elements of the door, which are not directly connected to the wheels necessary for moving the sliding door. The floor guide or router, which is installed and fixed in the floor itself, can be damaged and thus uprooted from the base, which can lead to contamination of the room. From the point of view of maintenance, the installation of the drive and automation, which are located next to the sliding guide, is problematic, and in the event of a malfunction, maintenance must be carried out by intervention in the clean room. Last but not least, cleaning is also problematic, because for example the door leaf can only be cleaned when the door is dismantled, which means that the clean space will be contaminated during dismantling and subsequent cleaning.

Zgoraj našteti problemi so bili izhodišče za razvoj izboljšanih drsnih vrat za čiste prostore z lastnostjo majhne prepustnosti zraka. Tehnični problem je torej konstrukcijska zasnova drsnih vrat, ki bo reševala zgoraj omenjene probleme obstoječih vrat na učinkovit način, tako da bo čim manj delcev lahko prodrlo v čisti prostor ter da bo čiščenje in servisiranje vrat lahko potekalo brez posega v čisti prostor.The problems listed above were the starting point for the development of improved sliding doors for clean rooms with the property of low air permeability. The technical problem is therefore the structural design of the sliding door, which will solve the above-mentioned problems of the existing door in an efficient way, so that as few particles as possible can penetrate into the clean room and that the cleaning and servicing of the door can take place without interfering with the clean room.

Stanje tehnikeState of the art

Patentna prijava W02005085575 opisuje avtomatska drsna vrata, ki ima vsaj eno vodilo, ki je stacionarno nameščeno na steno, vsaj eno avtomatsko enoto, ki je stacionarno nameščena na steno in ki vključuje pogon za vrata ter vsaj en voziček z vsaj enim koleščkom. Voziček je premičen po vodilu s pomočjo koleščka. Vodilo je oblikovano kot vlečen profil, ki se reže glede na potrebe. Avtomatska enota je oblikovana kot standardna enota z nespremenljivo dolžino, ki ustreza širini vrat. Voziček je oblikovan kot kontinuirana tirnica, njegova dolžina pa se lahko prilagaja. Ta rešitev se od pričujočega izuma razlikuje po obliki omenjenega vodila. Slabost vodila opisanega v W02005085575 je v tem, da ima več sestavnih delov, med katerimi se lahko nabirajo nečistoče.Patent application W02005085575 describes an automatic sliding door having at least one guide that is stationary mounted on the wall, at least one automatic unit that is stationary mounted on the wall and that includes a drive for the door and at least one carriage with at least one wheel. The trolley is moved along the guide with the help of a castor. The guide is designed as a drawn profile, which is cut according to needs. The automatic unit is designed as a standard unit with a fixed length corresponding to the width of the door. The trolley is designed as a continuous rail, and its length can be adjusted. This solution differs from the present invention in the form of said guide. The disadvantage of the guide described in WO2005085575 is that it has several components between which impurities can accumulate.

Opis rešitve tehničnega problemaDescription of the solution to the technical problem

Cilj izuma je optimizacija konstrukcije drsnih vrat, še posebno drsnega vodila in vseh pripadajočih elementov. Tehnični problem je rešen, kot je predstavljeno v neodvisnem zahtevku, medtem ko so prednostne rešitve definirane v odvisnih zahtevkih.The goal of the invention is to optimize the construction of the sliding door, especially the sliding guide and all associated elements. The technical problem is solved as presented in the independent claim, while preferred solutions are defined in the dependent claims.

Drsna vrata po izumu vključujejo okvir vrat, v katerega je vpeto vsaj eno vratno krilo, ki je drsno pomično na drsnem vodilu s pomočjo vsaj enega premično vpetega vozička s koleščki, pri čemer premičnost vratnega krila zagotavlja pogonska enota z motorjem. Jermen, ki zagotavlja premičnost, je na strani, kjer ni motorja vpet v proti-kolo, ki tako vodi jermen m preprečuje njegov izpad ali pomanjkljivo napetost. Običajno so vrata enoknlna ali dvokrilna, komponente izuma pa so pri obeh izvedbah enake oziroma delujejo na enak način.The sliding door according to the invention includes a door frame in which at least one door leaf is fixed, which is slidably movable on a sliding guide with the help of at least one movably mounted carriage with wheels, the mobility of the door leaf being provided by a drive unit with a motor. The belt that ensures mobility is on the side where the engine is not engaged in the counterwheel, which thus guides the belt and prevents it from falling out or lacking tension. Usually, doors are single or double-leaf, and the components of the invention are the same or work in the same way in both versions.

Bistvo izuma je v tem, da je cevasto drsno vodilo vrat ovalne oblike oziroma je prečni prerez vodila ovalne oblike, s čemer se naležna površina koleščkov, ki zagotavljajo premikanje vratnega krila, poveča. Posledično se zmanjša trenje in s tem obraba koleščkov, kar pomeni, da od njih odpada manj delcev. Prednostno se kot material za izdelavo drsnega profila uporabi nerjaveče jeklo, ki ima zelo majhno obrabo. Na vodilu so prednostno pripravljeni utori za naleganje in tesnjenje vrat, v katere se vsedejo koleščki, na katere je pritrjeno vratno krilo. Funkcija utorov je zagotavljanje tesnjenja, medtem ko sami utori nimajo vpliva na obrabo koleščkov, saj se površina naleganja slednjih praktično ne spremeni glede na vodilo brez utorov. Izboljšano drsno vodilo torej predvsem omogoča manjšo tvorbo neželenih delcev zaradi obrabe koleščkov, obenem pa omogoča večji odmik vratnega krila od drsnega vodila, kar posledično pomeni več prostora in lažji dostop za samo čiščenje, kar je ena od ključnih stvari pri vzdrževanju vrat.The essence of the invention is that the tubular sliding guide of the door is oval-shaped, or the cross-section of the guide is oval-shaped, which increases the bearing surface of the wheels that ensure the movement of the door leaf. As a result, friction and thus wear on the wheels is reduced, which means that less particles fall off them. Stainless steel, which has very little wear, is preferably used as the material for the production of the sliding profile. On the guide, grooves are preferably prepared for fitting and sealing the door, in which the castors to which the door leaf is attached fit. The function of the grooves is to ensure sealing, while the grooves themselves have no effect on the wear of the wheels, since the bearing surface of the latter practically does not change compared to the guide without grooves. The improved sliding guide therefore primarily enables less formation of unwanted particles due to the wear of the wheels, and at the same time enables a greater distance of the door leaf from the sliding guide, which in turn means more space and easier access for cleaning itself, which is one of the key things in door maintenance.

Drsna vrata po izumu so prednostno opremljena s prekrivno masko, ki prekriva drsno vodilo. Prekrivna maska je v približni obliki črke C, tako da je vertikalni del poravnan s steno oz. stropom, ko so vrata vgrajena, sama maska pa je enostavno snemljiva s pomočjo tečajev, prednostno narejenih iz PE plastike. Tečaji iz PE plastike ne vsebujejo gibljivih delcev, s tem omogočajo lažje čiščenje in zmanjšajo možnost kontaminiranja čistih prostorov. Na ta način je omogočen lažji dostop do vodila in možnosti čiščenja, prav tako se s poravnano površino maske s steno oziroma stropom izogne dodatni površini, kjer se lahko nabirajo prašni delci.Sliding doors according to the invention are preferably equipped with a covering mask that covers the sliding guide. The overlay mask is in the approximate shape of the letter C, so that the vertical part is aligned with the wall or ceiling when the door is installed, and the mask itself is easily removable with the help of hinges, preferably made of PE plastic. Hinges made of PE plastic do not contain moving particles, thus enabling easier cleaning and reducing the possibility of contaminating clean rooms. In this way, easier access to the guide and the possibility of cleaning is enabled, and with the aligned surface of the mask with the wall or ceiling, an additional surface where dust particles can accumulate is avoided.

Za lovljenje delcev, ki vseeno lahko nastanejo med odpiranjem in zapiranjem, je predviden vsaj en lovilec delcev, izmed katerih je prvi že omenjena prekrivna maska, ki prekriva drsno vodilo po njegovi celotni dolžini. Oblikovana je tako, da preprečuje, da bi obrabljeni koščki plastike, ki odpadajo od koleščkov, prosto padali v čisti prostor. Oblika prvega lovilca delcev, ki je hkrati prekrivna maska, je v osnovi oblike črke C, odvisno od vpetja lovilca, pri čemer pri izvedbi v obliki črke C vertikalni del ravna površina, zgornji del je oblikovan tako, da lahko nalega na tečaj, prednostno iz PE plastike, spodnji del pa se nahaja pod drsnim vodilom, tako da lahko učinkovito lovi morebitne delce. Spodnji del sega v notranjost konstrukcije vrat in je praviloma večji kot pa zgornji del, ki skrbi za pritrditev na vrata. Ravni vertikalni del se enostavno čisti m vzdržuje, medtem ko je dostop do spodnjega dela, kjer se lahko ulovijo delci omogočen z odstranitvijo prekrivne maske ali z odpiranjem le-te.At least one particle catcher is provided for catching particles that may still be generated during opening and closing, the first of which is the already mentioned cover mask that covers the sliding guide along its entire length. It is designed to prevent worn pieces of plastic that fall off the casters from falling freely into the clean area. The shape of the first particle trap, which is also an overlay mask, is basically C-shaped, depending on the trap's mounting, whereby in the C-shaped design, the vertical part is a flat surface, the upper part is designed so that it can rest on the hinge, preferably from PE plastic, and the lower part is located under the sliding guide, so that it can effectively catch any particles. The lower part reaches inside the door structure and is generally larger than the upper part, which takes care of fixing it to the door. The flat vertical part is easy to clean and maintain, while access to the lower part, where particles can be caught, is enabled by removing the cover mask or by opening it.

Lovilcev delcev je lahko tudi več, lahko so oblikovani kot približna črka C, pa tudi približna oblika črke S ali L. Drugi lovilec delcev je pokrivna ploščevina pogona, ki ima podobno obliko kot prvi lovilec delcev, torej, da je pod vodilom ustrezen spodnji del, na katerem se zadržijo morebitni delci nastali med delovanjem vrat. Prednostno je tretji lovilec delcev nameščen pod pogonsko jermenico, četrti lovilec delcev pa pod protikolo. Z večjim številom lovilcev delcev se izboljša lovljenje delcev in preprečevanje njihovega vdora v čisti prostor.There can also be more particle traps, they can be shaped like an approximate letter C, but also an approximate shape of the letter S or L. The second particle trap is the cover plate of the drive, which has a similar shape to the first particle trap, that is, that there is a corresponding lower part under the guide , on which any particles formed during door operation are retained. Preferably, the third particle catcher is located under the drive pulley and the fourth particle catcher is located under the counterwheel. With a greater number of particle traps, the trapping of particles and the prevention of their entry into the clean room are improved.

Drsna vrata po izumu so nadalje opremljena z izboljšanimi tesnili, ki preprečujejo ustvarjanje zračnih žepkov. Oblika tesnila je v prerezu približno pravokotna ali kvadratna, pri čemer je v spodnjem delu iz enega kota izhajajoči štrleči del, ki je usmerjen proti nasprotnemu spodnjemu kotu. Na ta način tesnilo preprečuje, da bi se nečistoče nabirale v prostorih, ki so težje dostopna za čiščenje, obenem se enostavno čisti. Tesnila so narejena iz kateregakoli materiala, ki je za ta namen odobren s strani FDA.Sliding doors according to the invention are further equipped with improved seals that prevent the creation of air pockets. The shape of the seal is approximately rectangular or square in cross-section, with a protruding part in the lower part coming out of one corner and directed towards the opposite lower corner. In this way, the seal prevents impurities from accumulating in areas that are more difficult to access for cleaning, and at the same time it is easy to clean. Seals are made of any material approved for this purpose by the FDA.

Prednostno so drsna vrata z izboljšanim vodilom po izumu oblikovana tako, da je avtomatski sklop in pogonski sklop postavljen v tehnični coni, t.j. etažni prostor nad vrati, ko se le-ta vgrajena, tako da ob posegu v te komponente vrat ni potrebno posegati v čisti prostor, kar poenostavi vzdrževanje in servisiranje vrat. Poseganje v čisti prostor je izjemno nezaželeno, izum pa to rešuje s posebno obliko vodila ter s prestavitvijo pogonskega in avtomatskega sklopa. Pogonski sklop je sestavljen iz ohišja s pokrovom, znotraj ohišja pa sklop vključuje motor, prednostno BLCD motor, pogonsko os z ležajem in ohišjem le-tega, sklopko za prenos med motorjem in pogonsko osjo in elektromagnetno tuljavo s tipalom za zaklepanje pogonske osi. Pogonski sklop je preko pogonske gredi in sklopke nadalje povezan na jermenico, ki preko jermena poganja vozičke kril. Avtomatski sklop (tudi krmilna omarica oz. avtomatika) je povezan s pogonskim sklopom preko vodnikov (kablov) in služi za avtomatizirano delovanje vrat. Sestavljen je iz ohišja, napajalnika, baterij, varoval, krmilne elektronike, relejev, priključnih sponk in vodnikov.Preferably, the sliding door with an improved guide according to the invention is designed in such a way that the automatic unit and the drive unit are placed in the technical zone, i.e. floor space above the door when it is installed, so that when tampering with these door components, it is not necessary to tamper with the clean room, which simplifies the maintenance and servicing of the door. Encroachment into the clean space is extremely undesirable, and the invention solves this with a special guide shape and by repositioning the drive and automatic assembly. The drive assembly consists of a housing with a cover, and inside the housing the assembly includes a motor, preferably a BLCD motor, a drive axle with a bearing and its housing, a clutch for transmission between the engine and the drive axle and an electromagnetic coil with a sensor for locking the drive axle. The drive assembly is further connected to a pulley via a drive shaft and a clutch, which drives the wing carriages via the belt. The automatic unit (also control box or automation) is connected to the drive unit via conductors (cables) and serves for the automated operation of the door. It consists of a housing, power supply, batteries, fuses, control electronics, relays, connection terminals and conductors.

Za dodatno preprečevanje posegov v čisti prostor in preprečevanje vdora nečistoč v čisti prostor je prilagojeno tudi vpetje vrat v tla prostora. Namesto talnega vodila in dodatnih stebričkov iz nerjavečega jekla za zaščito vrat je predviden nastavljiv povišan talni stebriček z drsnikom, katerega funkcija je obenem kot zaščita vrat in talno vodilo. Na ta način se zmanjša število elementov fiksiranih v tla. Prav tako je talni drsnik dizajniran tako, da ima ločeno talno ploščo, katera je pričvrščena v tla, na ploščo je pa potem nameščen stebriček s talnim drsnikom. V primeru poškodbe stebrička ne pride do poškodbe talne plošče in je preprečena možnost kontaminacije. Sila loma stebrička se lahko definira preko uporabe različnih vpetij stebrička in materialov vpetij, ki so lahko inox, HPL, PE in podobni. Vpetje je lahko izvedeno preko vijaka in lomljive ploščice oziroma podložke ter dodatnih vijakov, ki s pomočjo sider poskrbijo za zanesljivo vpetje. Drsnik iz PE plastike, ob katerem drsijo vrata, je na stebriček nameščen kot prstan, ki obenem služi kot drsni člen ter prekrije pritrdilne vijake. S tem je izboljšano in olajšano čiščenje.For additional prevention of interventions in the clean room and prevention of impurity entering the clean room, the locking of the door to the floor of the room is also adjusted. Instead of a floor rail and additional stainless steel posts for door protection, an adjustable elevated floor post with a slider is provided, which functions as a door protection and floor guide at the same time. In this way, the number of elements fixed in the ground is reduced. Also, the floor slide is designed to have a separate floor plate that is fixed into the floor, and then the post with the floor slide is placed on top of the plate. In case of damage to the column, the floor plate is not damaged and the possibility of contamination is prevented. The breaking force of the post can be defined through the use of different post mounts and mount materials, which can be stainless steel, HPL, PE and similar. Fastening can be done via a screw and a breakable plate or washer and additional screws, which ensure reliable fastening with the help of anchors. The slide made of PE plastic, along which the door slides, is mounted on the post as a ring, which also serves as a sliding link and covers the fastening screws. This improves and facilitates cleaning.

Vratno krilo je oblikovano tako, da ga je možno v celoti očistiti. Vrata po izumu imajo več načinov delovanj, in sicer:The door wing is designed in such a way that it can be completely cleaned. The door according to the invention has several modes of operation, namely:

- Avtomatsko letno (polno odpiranje),- Automatic annual (full opening),

- Avtomatsko zimsko (delno odpiranje),- Automatic winter (partial opening),

- Enosmerno letno (polno odpiranje),- One-way annual (full opening),

- Enosmerno zimsko (delno odpiranje),- One-way winter (partial opening),

- Zaprto/zaklenjeno (vrata zaprta/zaklenjena),- Closed/locked (door closed/locked),

- Odprto (vrata odprta),- Open (door open),

- Stop (motor odklopljen, omogočeno ročno premikanje vrat), ter- Stop (engine disconnected, manual door movement enabled), ter

- Čiščenje, kjer se vrata polno odprejo, ročno premikanje vrat pa je omogočeno. Kontrolo izbire delovanja in delovanja v izbranem načinu izvaja avtomatika na znane načine. V načinu delovanja čiščenja, je vrata možno odpreti ročno ali avtomatsko do skrajnega odprtega položaja mimo drsnika, kjer je krilo za potrebe čiščenja mogoče nagniti za cca. 10°. Za potrebe čiščenja se izvede sledeče korake: a) izbere se način delovanja čiščenje,- Cleaning where the door opens fully and manual movement of the door is enabled. Control of the selection of operation and operation in the selected mode is carried out by automation in known ways. In the cleaning mode, the door can be opened manually or automatically to the extreme open position past the slider, where the sash can be tilted for cleaning purposes by approx. 10°. For cleaning purposes, the following steps are performed: a) the cleaning mode is selected,

b) vrata se avtomatsko odprejo v skrajno odprt položaj mimo povišanega talnega stebrička,b) the door automatically opens to the fully open position past the raised floor post,

c) vrata je s pomočjo koleščkov vozičkov možno nagniti za cca. 10° kar omogoča čiščenje predelov tesnil oz. robove vratnega krila,c) the door can be tilted by approx. with the help of the trolley wheels. 10°, which enables cleaning of the seal areas or the edges of the door leaf,

d) Vrata je možno ročno pomikati po vodilu, saj je pogonska enota v tem načimu delovanja neaktivna,d) It is possible to manually move the door along the rail, as the drive unit is inactive in this mode of operation,

Slika 1 prikazuje dvokrilna drsna vrata 1 za čiste prostore po možnem izvedbenem primeru, kjer so vrata 1 sestavljena iz dveh kril 1a,1b, in sicer levega 1a in desnega 1b, pri čemer je pogonski sklop 11 nameščen nad vodilom 1 c vrat, proti-kolo 12 pa je nameščeno na drugi strani od pogonskega sklopa 11. Slika 1 ter tudi slika 2 v prerezu vrat 1 iz slike 1 v ravnini A-A prikazujeta pogonski sestav 11, in sklop vodila, ki ga sestavljajo manjši voziček 14, večji voziček 13, ki sta oba namenjena premikanju kril la, 1b, po drsnem vodilu 16, jermen 15 in vpenjalo zanj 15a. Pogonski sestav 11 je nameščen nad vodilom vrat 1c, medtem ko so vrata v tla vpeta s pomočjo talnih stebričkov 2.Figure 1 shows a double-winged sliding door 1 for clean rooms according to a possible implementation example, where the door 1 consists of two wings 1a, 1b, namely the left 1a and the right 1b, and the drive unit 11 is installed above the guide 1c of the door, counter- and the wheel 12 is installed on the other side of the drive unit 11. Figure 1 and also Figure 2 in the cross-section of the door 1 from Figure 1 in the A-A plane show the drive assembly 11 and the guide assembly, which consists of a smaller carriage 14, a larger carriage 13, which both are intended to move the wings 1a, 1b along the sliding guide 16, the belt 15 and the clamp for it 15a. The drive assembly 11 is mounted above the door guide 1c, while the door is anchored to the floor by means of floor posts 2.

Slika 3 prikazuje cevasto drsno vodilo 16 vrat, ki je v prerezu ovalne oblike, s čemer se naležna površina koleščkov vozičkov 13, 14, ki zagotavljajo premikanje vratnega krila 1a, 1 b, poveča. Dolžina drsnega vodila 16 se prilagodi dimenzijam vrat, narejeno pa je iz nerjavečega jekla.Figure 3 shows the tubular sliding guide 16 of the door, which has an oval cross-section, with which the bearing surface of the wheels of the carriages 13, 14, which ensure the movement of the door leaf 1a, 1b, increases. The length of the sliding guide 16 is adjusted to the dimensions of the door, and it is made of stainless steel.

Za lovljenje delcev, ki vseeno lahko nastanejo med odpiranjem in zapiranjem, je predviden vsaj en lovilec delcev, ki je preoblikovana že omenjena prekrivna maska 18, ki prekriva drsno vodilo po njegovi celotni dolžini. Oblikovana je tako, da preprečuje, da bi obrabljeni koščki plastike, ki odpadajo od koleščkov, prosto padali v čisti prostor. Prekrivna maska je v obliki črke C (slika 4), tako da je vertikalni del 18b poravnan s steno oz. stropom, ko so vrata vgrajena, spodnji del sega 18c v notranjost konstrukcije vrat in je praviloma večji kot pa zgornji del 18a, ki skrbi za pritrditev na vrata. Ravni vertikalni del 18b se enostavno čisti in vzdržuje, medtem ko je dostop do spodnjega dela 18c, kjer se lahko ulovijo delci omogočen z odstranitvijo ali odpiranjem prekrivne maske 18. Sama maska je enostavno snemljiva oziroma se odpre s pomočjo tečajev 18d, prednostno narejenih iz PE plastike. Tečaji iz PE plastike ne vsebujejo gibljivih delcev, s tem omogočajo lažje čiščenje in zmanjšajo možnost kontaminiranja čistih prostorov. Na ta način je omogočen lažji dostop do vodila in možnosti čiščenja, prav tako se s poravnano površino maske s steno oziroma stropom izogne dodatni površini, kjer se lahko nabirajo prašni delci. Predvidena je tudi konzola (20) za zaklepanje maske, ki poskrbi, da se ključavnica, primerna za čiste prostore, zaklene.At least one particle catcher is provided for catching particles that may still be generated during opening and closing, which is a modified cover mask 18, which covers the sliding guide along its entire length. It is designed to prevent worn pieces of plastic that fall off the casters from falling freely into the clean area. The cover mask is in the shape of the letter C (Figure 4), so that the vertical part 18b is aligned with the wall or ceiling, when the door is installed, the lower part 18c extends inside the door structure and is generally larger than the upper part 18a, which takes care of fixing it to the door. The flat vertical part 18b is easy to clean and maintain, while access to the lower part 18c, where particles can be caught, is made possible by removing or opening the cover mask 18. The mask itself is easily removable or opened with the help of hinges 18d, preferably made of PE plastic. Hinges made of PE plastic do not contain moving particles, thus enabling easier cleaning and reducing the possibility of contaminating clean rooms. In this way, easier access to the guide and the possibility of cleaning is enabled, and with the aligned surface of the mask with the wall or ceiling, an additional surface where dust particles can accumulate is avoided. A console (20) is also provided for locking the mask, which ensures that the lock suitable for clean rooms is locked.

Drugi lovilec 19a delcev je pokrivna pločevina pogona, ki ima podobno obliko kot prvi lovilec delcev, torej, da je pod vodilom ustrezen spodnji del, na katerem se zadržijo morebitni delci nastali med delovanjem vrat. Tretji lovilec 19b delcev je nameščen pod pogonsko jermenico, četrti lovilec (ni prikazan na sliki) delcev pa pod proti-kolo.The second particle catcher 19a is a cover plate of the drive, which has a similar shape to the first particle catcher, i.e. under the guide there is a corresponding lower part on which any particles generated during the operation of the door are retained. The third particle catcher 19b is located under the drive pulley, and the fourth particle catcher (not shown) is located under the counterwheel.

Za dodatno preprečevanje posegov v čisti prostor in preprečevanje vdora nečistoč v čisti prostor je prilagojeno tudi vpetje vrat v tla prostora, in sicer preko nastavljivega povišanega talnega stebrička z drsnikom, kot je prikazan na sliki 5. Funkcija stebrička je hkrati zaščita vrat in talno vodilo.In order to additionally prevent interventions in the clean room and to prevent impurities from entering the clean room, the fastening of the door to the floor of the room is adapted, namely via an adjustable elevated floor post with a slider, as shown in Figure 5. The post's function is both door protection and a floor guide.

Stebriček 2 ima osnovno telo 21, ki se s sidri 23 namesti v tla, na osnovno telo 21 pa je z vijaki 25 nameščeno sekundarno drsno vodilo, ki služi za vodenje kril pri lomu stebrička. Pokrivno drsno vodilo 27, znotraj katerega je z vijakom 24 pritrjena lomljiva ploščica 26 na površino cevi 28. Pokrivno drsno vodilo iz PE, ki je nameščeno kot prstan na stebriček 2, omenjeno vodilo pa obenem služi kot drsni člen ter prekrije pritrdilne vijake 24 in 25. Stebriček je dodatno opremljen s t.i. sterilization lock, ki je v bistvu mehanska ključavnica za zaklepanje vrat v zaprtem ali odprtem stanju. Namenjena je dodatni zaščiti med opravljanjem sterilizacije prostora, da v njega ni možen nepooblaščeni dostop in za zaščito vrat med samo instalacijo in gradnjo objekta, da vrat ni mogoče ročno zapirati, temveč so mehansko zaklenjena v odprtem stanju. Omenjena ključavnica vključuje montažno ploščo, ki je je pritrjena z vijakoma na stebriček. Na montažno ploščo je nameščena rotirajoča ključavnica, ki je z vijakom povezana z navojnim vretenom. Na navojno vreteno je preko večstopenjskega navoja nameščen zaklep. Pri rotiranju ključavnice se navojno vreteno prav tako rotira in preko navojev potiska zaklep iz ali v sam stebriček, odvisno od smeri rotiranja. Za drsenje poskrbi drsnik iz umetne mase, vodenje je izvedeno s konzolo, ki je privarjena v stebriček.Post 2 has a base body 21, which is installed in the ground with anchors 23, and on the base body 21, a secondary sliding guide is mounted with screws 25, which serves to guide the wings when the post breaks. Cover sliding guide 27, inside which a breakable plate 26 is fixed to the surface of the tube 28 with a screw 24. Cover sliding guide made of PE, which is placed as a ring on the post 2, and said guide also serves as a sliding link and covers the fixing screws 24 and 25 The post is additionally equipped with a so-called sterilization lock, which is basically a mechanical lock for locking the door in the closed or open state. It is intended for additional protection during the sterilization of the room, so that unauthorized access is not possible, and to protect the door during the actual installation and construction of the building, so that the door cannot be closed manually, but is mechanically locked in the open state. Said lock includes a mounting plate that is attached to the post with two screws. A rotating lock is mounted on the mounting plate, which is connected to the threaded spindle with a screw. A lock is installed on the threaded spindle via a multi-stage thread. When the lock is rotated, the threaded spindle also rotates and pushes the lock through the threads from or into the post itself, depending on the direction of rotation. Sliding is provided by a slide made of synthetic material, the guidance is carried out with a console that is welded to the post.

Drsna vrata po izumu so nadalje opremljena z izboljšanimi tesnili 3, ki preprečujejo ustvarjanje zračnih žepkov. Oblika tesnila je prikazana na sliki 6 in je v prerezu približno kvadratna, pri čemer je v spodnjem delu iz enega kota izhajajoči štrleči del, ki je usmerjen proti nasprotnemu kotu. Na ta način tesnilo preprečuje, da bi se nečistoče nabirale v prostorih, ki so težje dostopna za čiščenje ter se enostavno čisti.The sliding door according to the invention is further equipped with improved seals 3 which prevent the creation of air pockets. The shape of the seal is shown in Figure 6 and is roughly square in cross-section, with a protruding part in the lower part coming out of one corner and pointing towards the opposite corner. In this way, the seal prevents impurities from accumulating in areas that are more difficult to access for cleaning and is easy to clean.
