Description

Izum se nanaša na pozicioniranje šipe, potujoče na transporterju, zlasti šipe, segrete nad zmehčišče glede na usločitev in/ali toplotno obdelavo za spremembo določenih mehanskih značilnosti šipe. Bolj konkretno izum zadeva proizvodnjo šip za motoma vozila.The invention relates to the positioning of the pile traveling on the conveyor, in particular the piles heated above the softener with respect to the contraction and / or heat treatment to alter certain mechanical characteristics of the pile. More specifically, the invention relates to the manufacture of motor vehicle pane windows.

Da bi dobili primerno šipo z optimalno usločenostjo in zadovoljivo optično kakovostjo je pomembno, da je šipa, predno jo zgrabijo orodja za usločanje in/ali toplotno obdelavo, pravilno postavljena. Vendar pa šipe, kije segreta čez temperaturo mehčanja, ni mogoče držati s prijemali ali drugimi zgrabilnimi elementi, če ni mogoče sprejeti sledi, ki jih orodja nujno pustijo za seboj. Prav tako je treba šipo postaviti glede na orodja pred segrevanjem, t.j. orodja se morajo zaustaviti za skrajno dolgo časa, kar vodi k zelo visokim proizvodnim stroškom.In order to obtain a suitable pane with optimum resolution and satisfactory optical quality, it is important that the pile is properly positioned before being grabbed by the tools for machining and / or heat treatment. However, piles heated beyond the softening temperature cannot be held by grips or other gripping elements unless the traces that the tools necessarily leave behind cannot be accepted. The pile should also be positioned relative to the pre-heating tools, i.e. the tools must stop for an extremely long time, which leads to very high production costs.

Ti problemi sledi prijemal in zaustavljanja orodij se zmanjšajo v slučaju postopkov usločanja in/ali toplotne obdelave, pri katerih se prva stopnja, namreč segrevanje šipe, izvaja v peči, skozi katero šipe potujejo npr. na kotalni postelji. Problem postavljanja pa ni rešen, ker so potovalne hitrosti in dolžine peči take, da dve zaporedni si šipi nimata vedno natanko isti tirnici. Te razlike v tirnicah lahko vodijo k dvema vrstama napak, namreč k drsenju pravokotno na os transporterja in zasuku glede na omenjeno os, in tem napakam se da izogniti z bočnimi položajnimi sredstvi in čelnimi položajnimi sredstvi.These problems are followed by gripping and stopping of the tools in the case of decision-making and / or heat treatment processes in which the first stage, namely the heating of the pile, is carried out in a furnace through which the piles pass, e.g. on a rolling bed. The setup problem is not solved, however, because the traveling speeds and furnace lengths are such that two consecutive piles do not always have exactly the same rail. These differences in rails can lead to two types of defects, namely, sliding perpendicular to the conveyor axis and rotation relative to said axis, and these errors can be avoided by lateral position means and front position means.

Kot je razvidno iz EP-A- 267.120, je bočno vodenje doseženo npr. s pomočjo vodilnih palic, ki se gibljejo skupaj z napredovanjem v smeri naprej gibanja transporterja in ki določajo prehod za šipo. Steklo podrsava na teh palicah, ki ga pa ne zaustavijo.As shown in EP-A-267,120, lateral guidance is achieved e.g. by means of guide bars that move in conjunction with the forward movement of the conveyor and which determine the passage for the pile. Glass slides on these bars, but they don't stop it.

Ker pa šipe, ki so predvidene za okna motornih vozil, nikoli niso pravokotne plošče in skoraj praviloma se njihova širina od enega konca okna do drugega spreminja, omenjeno bočno pozicioniranje ne zadošča in mora biti dopolnjeno s čelnim pozicioniranjem, ki po EP-A- 267.120 vključuje fazo zaustavljanja šipe. Da šipo usmerijo, kot je treba, je na njeni progi razporejeno zaustavljalno sredstvo, ki sestoji iz npr. dveh nastavkov in ki je nujno nataknjeno na en konec vodilnega roba šipe in je položajno držano primerno dolgo časa, tako da transporter med nadaljnjim gibanjem šipe le-to lahko preusmeri. Dokler zaustavljalno sredstvo drži šipo vsaj delno zaustavljeno, šipa podrsava na mestu na kolescih, ki lahko pustijo na steklu odtis, katerega se zaradi visoke temperature kaj lahko opazi. Tako je čelno pozicioniranje vir številnih optičnih okvar.However, since the windows intended for motor vehicle windows are never rectangular panels and their width varies from one end of the window to the other almost entirely, the lateral positioning mentioned is not sufficient and must be supplemented by frontal positioning, which according to EP-A-267.120 involves the stop phase of the pile. To direct the pile as it should, a stop means is arranged on its line, consisting of e.g. two nozzles, which is necessarily attached to one end of the leading edge of the pile and is positionally held for an appropriate length of time so that the conveyor can be re-positioned during further movement of the pile. As long as the stopping agent holds the pane at least partially stopped, the pile slides in place on the wheels, which can leave an imprint on the glass that can be spotted due to the high temperature. Thus, frontal positioning is the source of many optical defects.

Predmet izuma je nov postopek čelnega pozicioniranja šipe, ki minimizira trenje stekjla ob kolescih in s tem tveganje nastanka sledi.The subject of the invention is a new method of frontal positioning of the pane that minimizes the friction of the glass against the wheels and thus the risk of trace formation.

Rešitev, ki jo predlaga izum, obsega postopek pozicioniranja šipe, potujoče na transporterju, po katerem je na poti šipe vključen zaustavljalni element, na katerega se zatakne en konec vodilnega roba šipe in ki ostane v stiku s steklom primerno dolgo za izvedbo preusmeritve, ki jo opravi transporter, ko brez prestanka premika šipo, pri čemer je izum značilen po tem, da zaustavljalno sredstvo v času pozicioniranja izvaja translacijsko gibanje vzporedno s smerjo potovanja stekla v isti smeri kot slednje in pri hitrosti, kije nižja od hitrosti gibanja transporterja.The solution of the invention comprises a process of positioning a pile traveling on a conveyor, in which a stop element is engaged in the pile path, to which one end of the leading edge of the pile is stuck and which remains in contact with the glass for a long time to perform the diversion, which perform the conveyor when it moves the pile without ceasing, the invention being characterized in that the stopping means performs translational motion during positioning in parallel with the direction of travel of the glass in the same direction as the latter and at a speed lower than the speed of movement of the conveyor.

V primerjavi s postopki iz stanja tehnike čelno pozicioniranje šipe po izumu ne vključuje zaustavljanja potovanja šipe, tako da se vroče steklo na kolescih samo upočasni, kar pomeni, da se ohrani optična kakovost stekla.In comparison with the prior art, the frontal positioning of the pane according to the invention does not involve stopping the pile travel so that the hot glass on the wheels only slows down, which means that the optical quality of the glass is maintained.

Smotrno se zaustavljalni element giblje, predno nanj zadene prednji konec šipe. To gibanje se prednostno sproži z zaznavanjem pred prispetjem šipe prednostno s pomočjo svetlobne pregrade, kakršna je znana npr. iz EP-A- 267.850.The stopping element is advantageously moved before being hit by the front end of the pile. This movement is preferably triggered by detection prior to the arrival of the pile, preferably by means of a light barrier such as is known, e.g. from EP-A-267,850.

Ko je pozicioniranje slednjič vzpostavljeno, se v nadaljnjem zaustavljalni element primerno pospeši na hitrost, kije višja od hitrosti transporterja, tako da se zaustavljalni element loči od šipe brez nevarnosti, da bi slednjo malenkostno dvignil, pri čemer šipa zaradi svoje visoke temperature stremi za tem, da se prilepi na zaustavljalni element.When the positioning is last established, the stopping element is further appropriately accelerated to a speed which is higher than the speed of the conveyor, so that the stopping element is separated from the pile without risking the latter to rise slightly, leaving the pier due to its high temperature. to attach to the stop element.

Od trenutka, ko je zaustavljalni element zadosti odmaknjen od šipe, se ta element lahko povleče nazaj, t.j. odstrani s proge šipe, in se seveda z visoko hitrostjo vrne v svoj izhodiščni položaj, kjer čaka na naslednjo šipo. Očitno se to vračanje izvaja pri zadostnem odmiku zaustavljalnega elementa od proge šipe, s čimer je zagotovljeno, da se zaustavljalni element ne dotika šipe.From the moment the stopping element is sufficiently moved away from the pile, this element can be pulled back, i.e. removes the piles from the track, and naturally returns to its starting position at high speed, where it awaits the next pile. Obviously, this return is made at a sufficient distance from the stop of the stop element, so that the stop element does not touch the stop.

Predmet pričujoče prijave je tudi naprava, ki je zasnovana za izvedbo predloženega postopka pozicioniranja. Ta naprava je v glavnem sestavljena iz nosilca, na katerega je pritrjen zaustavljalni element, pri čemer je nosilec podprt na vsakem svojem koncu s tirnicama, ki sta vzporedni z osjo transporterja, katerega nosijo premakljivi vozički, ki potujejo na kolescih, pri čemer se premik vozičkov opravi z obračanjem polža ali dvigalke, razporejene vzporedno z osjo transporterja.The subject of this application is also a device designed to perform the positioning process provided. This device mainly consists of a carrier to which a stop element is attached, the carrier being supported at each end by rails parallel to the conveyor axis, which is carried by movable carts traveling on wheels, with the movement of the carts. performed by turning the auger or hoist arranged parallel to the conveyor axis.

Premik nosilca v navpični smeri za prehod opornikov v zgornji položaj na koncu pozicioniranja in nato nazaj v spodnji položaj za šipo se opravi prednostno z vgraditvijo kolesca na izsrednosti, ki jo vključi pnevmatska vrtilna dvigalka, prednostno z digitalnim električnim krmiljenjem, in ki je funkcija položaja vozička in smeri njegove premaknitve.Movement of the carrier in the vertical direction for the passage of the struts to the upper position at the end of positioning and then back to the lower position for the pile is preferably done by mounting the roller on a pivot provided by the pneumatic rotary lift, preferably by digital electric control, which is a function of the position of the trolley and the direction of its displacement.

Smotrno je za hkraten pogon dveh vozičkov, razporejenih na vsaki strani transporterja, uporabljen isti motor, pri čemer prenosniški trakovi zavrtijo polže ali dvigalke z enakimi hitrostmi. Ta motor, ki je razporejen npr. pod transporteijem, je prednostno opremljen z uravnalnikom hitrosti, ki omogoča gibanje vozičkov s sorazmerno nizko konstantno hitrostjo v smeri potovanja transporterja med pozicioniranjem in nato s pospeševanjem za potrebe oddvojitve zaustavljalnega elementa in slednjič zagotovi vračalno gibanje prednostno s hitrostjo, ki je višja od hitrosti gibanja zunaj, s čimer so omogočene višje proizvodne hitrosti s kratkim presledkom med zaporednima šipama.It is advisable to use the same engine for the simultaneous operation of two trolleys arranged on each side of the conveyor, with the conveyor belts rotating the augers or elevators at the same speed. That engine that is deployed e.g. under transportei, it is preferably equipped with a speed adjuster which allows the carts to move at a relatively low constant speed in the direction of travel of the conveyor during positioning and then by acceleration for the purpose of detaching the stopping element, and the latter provides return movement preferably at a speed higher than the speed of movement outside. , allowing higher production speeds with a short space between successive piles.

Po definiciji je šipa popolno orientirana, ko je njen vodilni rob poravnan z zaustavljalnim elementom. Ta zaustavljalni element je narejen npr. kot enojen zvezni del v smislu zaslona ali kot niz medsebojno razmaknjenih delov v smislu naslonov. V splošnem gre za dva naslona, ki sta do skrajnosti razmaknjena, računajoč pri tem z dolžino vodilnega roba s ciljem, doseči večjo natančnost pozicioniranja. Vgraditev teh naslonov prednostno dopušča regulacijo njunega položaja relativno glede na nosilec vsaj v smeri pravokotno nanj, tako da je omogočeno pozicioniranje šip, katerih vodilni rob ne poteka pravokotno na os transporterja. Koristna je tudi možnost regulacije razmika med naslonoma. Tako je npr. možno v ta namen uporabiti na drsniku zasnovane montažne sklope.By definition, a pile is perfectly oriented when its leading edge is aligned with the stop element. This stopping element is made e.g. as a single continuous section in the sense of the screen or as a series of spaced apart parts in the sense of the backrests. In general, these are two backrests that are spaced to the extreme, with the aiming length of the leading edge, to achieve greater positioning accuracy. The mounting of these backrests preferably permits the regulation of their position relative to the carrier at least in a direction perpendicular to it, so that positioning of piles whose leading edge does not extend perpendicular to the conveyor axis is enabled. The ability to adjust the spacing between the backrests is also useful. Thus, e.g. it is possible to use mounting assemblies based on the slider for this purpose.

Nadaljnje podrobnosti in smotrne značilnosti izuma so v nadaljnjem opisane upoštevaje dva lista skic, v katerih kaže sl. 1 šipo v tlorisu pred pozicioniranjem in po njem, sl. 2 vsebino sl. 1 v perspektivni projekciji, in sl. 3 napravo za pozicioniranje po izumu v prerezu po črti A - A s sl. 1.Further details and expedient features of the invention are described below with reference to two sheets of drawings in which FIG. 1 is a plan view of the pile before and after positioning; FIG. 2 shows the contents of FIG. 1 in perspective view, and FIG. 3 is a cross-sectional view of the invention according to the invention in cross-section along line A - A of FIG. 1.

Sl. 1 poenostavljeno kaže šipo 1, ki potuje v smeri, ki jo označuje puščica Ffna transporterju z osjo 2, pri čemer transporter tvori postelja 3 gnanih valjev. Šipa je pripravljena za vstop v npr. usločevalno postajo, zlasti tako po FR-A-2.549.465 ali FR-A-2.6Q4.992. Šipa je v ta namen segreta na temperaturo blizu 650 °C, kar jo naredi v bistvu plastično in občutljivo na to, da jo predmet, ki pride v stik z njo, zaznamuje. Vrtenje valjev 3 podeli steklu hitrost VI, ki znaša npr. okoli 20 cm/s.FIG. 1 shows in a simplified fashion a pile 1 traveling in the direction indicated by the arrow Ffna to the conveyor with axis 2, wherein the conveyor is formed by a bed of 3 driven cylinders. The pile is ready for entry into e.g. decision-making station, in particular in accordance with FR-A-2.549.465 or FR-A-2.6Q4.992. For this purpose, the pile is heated to a temperature near 650 ° C, which makes it essentially plastic and sensitive to being marked by the object that comes in contact with it. The rotation of the cylinders 3 gives the glass a velocity VI of, e.g. about 20 cm / s.

Nad transporterjem je vzporedno z valji razporejen nosilec 4. K omenjenemu nosilcu 4 sta priključeni npr. preko drsnikov roki 5, ki nosita naslona 6, 7, ki sta na drsni način fiksirana na rokah 5. Naslona 6, 7 napredujeta v smeri transporterja, ravna črta, ki poteka čez ta naslona, pa ustreza želenemu položaju za vodilni rob šipe.Above the conveyor, a carrier 4 is arranged in parallel with the cylinders. through the sliders of the arms 5, which support the backs 6, 7, which are slidably fixed on the arms 5. The backs 6, 7 advance in the direction of the conveyor, and the straight line passing through these backs corresponds to the desired position for the leading edge of the bar.

Kot se da v podrobnostih videti s sl. 2, je nosilec 4 na svojih konceh podprt s tirnicama, razporejenima na vsakokratni strani transporterja in vzporedno z osjo 2. Tirnici 8, 8’ tečeta po kolesih 9, 9’ in 10, 10’ in ju translatorno poganjata vozička 11, 11’. Voziček se premika s pomočjo dvigalke 12, ki je vzporedna s tirnicama 8 in katero vrti jermen 13, katerega poganja motor, ki je razporejen pod transporterjem. Podobna je stvar z vozičkom 11’, tako daje nosilec gnan z isto hitrostjo na obeh svojih koncih.As can be seen in detail from FIG. 2, the carrier 4 is supported at its ends by the rails arranged on each side of the conveyor and parallel to the axis 2. The rails 8, 8 'run on wheels 9, 9' and 10, 10 'and are driven by the trolleys 11, 11'. The trolley is moved by means of a lift 12 parallel to the rails 8 and rotated by a belt 13 driven by an engine arranged under the conveyor. It's similar to a trolley 11 ', so the carrier is driven at the same speed at both ends.

Kolesi 9 in 10 sta rabljeni za dviganje in spuščanje nosilca in naslonov, ki sta združena z njim. Kolo 9 je prednostno na fiksni višini in se prosto vrti. Nizvodno razporejeno kolo 10 se nahaja na izsredniku, katerega premika npr. vrtilna pnevmatska dvigalka. Slednjo smotrno vklaplja digitalno električno krmilje, ki je odvisno od položaja vozička in smeri njegovega premika.Wheels 9 and 10 are used to raise and lower the carrier and the struts associated with it. Wheel 9 is preferably at a fixed height and rotates freely. The downstream spaced wheel 10 is located on a straightener, which is moved e.g. rotary pneumatic lift. The latter is intelligently switched on by the digital electrical control, which depends on the position of the trolley and the direction of its movement.

Pozicionimi cikel je takle: V čakalnem položaju se nosilec nahaja nad valji in na zadosti velikem odmiku od transporterja, tako da sta opori v neaktivnem položaju; z drugimi besedami, gre za dvignjeni položaj. Ko šipa vstopi v pozicionirno polje, jo zazna brezkontaktni detektor 15, npr. svetlobna zavesa, ki je združena s fotoelektrično celico ali kamero. Naslona se zatem spustita v spodnji položaj, torej v aktivni položaj. Hkrati ali s časovno zakasnitvijo, ki je fiksirana kot funkcija razmika med detektorjem 15 in naslonoma 6, 7, se vključi premikanje nosilca 4 vzporedno z osjo 2 transporterja. Časovna zakasnitev je smotrno izbrana tako, da se pospeševalna faza, v kateri nosilec 4 od mirovanja prejme konstantno hitrost V2, konča v trenutku, ko konec vodilnega roba na čelu zadene ob prvi naslon 7.The positioning cycle is as follows: In the waiting position, the carrier is located above the rollers and at a sufficient distance from the conveyor so that the supports are in the inactive position; in other words, it is a raised position. When the pile enters the positioning field, it is detected by a contactless detector 15, e.g. a light curtain paired with a photoelectric cell or camera. The backrests are then lowered to the lower position, ie to the active position. At the same time or with a time delay fixed as a function of the distance between the detector 15 and the backrests 6, 7, the movement of the carrier 4 in parallel with the axis 2 of the conveyor is engaged. The time delay is suitably chosen such that the accelerating phase in which the carrier 4 receives a constant velocity V2 from standstill ends when the end of the leading edge on the forehead hits the first abutment 7.

Iz razloga splošnega dimenzioniranja je razdalja d2, ki jo pokrivata naslona, omejena, tako da mora biti V2 zadosti majhna, da razdalja dl, katero v istem času lahko pokrije šipa do skrajnega zadka, ustreza, da omenjeni konec ujame naslon 6, ki v istem času pokriva razdaljo d2. Da se zmanjša trenje, kateremu je podvržena šipa, ki jo drži naslon 7, mora biti hitrost V2 kar se da blizu hitrosti VI. Dober kompromis privede do izbire hitrosti V2 npr. manj od polovice hitrosti VI transporterja.For reasons of general sizing, the distance d2 covered by the backrests is limited so that V2 must be sufficiently small so that the distance dl, which at the same time can cover the pile to the extreme rear, corresponds to said end catching the backrest 6, which in the same time covers distance d2. In order to reduce the friction to which the pillar supported by the support 7 is subjected, the velocity V2 should be as close as possible to the velocity VI. A good compromise leads to the choice of speed V2 e.g. less than half the speed of the VI conveyor.

Ob koncu potovanja se morata naslona 6 in 7 potegniti nazaj, da lahko šipa nadaljuje s potovanjem. Da je zagotovljeno, da steklo (ki se zaradi svoje visoke temperature nekoliko prilepi na naslona) v trenutku, ko sta naslona dvignjena, ne teži k premikanju proč s transporterja, se to potegovanje nazaj izvaja dvostopenjsko, namreč naslona se pospešita do hitrosti V2’, ki je večja od VI, od stekla pa se oddaljita s pomočjo kolesa 10.At the end of the journey, the rests 6 and 7 must be pulled back so that the pile can continue traveling. In order to ensure that the glass (which, due to its high temperature, adheres slightly to the backrests) does not tend to move away from the conveyor at the moment when the backrests are lifted, this retraction is performed in two stages, namely, the backrests are accelerated to the speed V2 ', larger than VI and away from the glass by means of the wheel 10.

Nosilec, ki nosi naslona, zatem pride prednostno z visoko hitrostjo v začetni čakalni položaj, kjer je pripravljen za pozicioniranje naslednje šipe. V določenih slučajih je hitrost potovanja šipe zelo visoka, kar včasih pogojuje vračalne hitrosti nad hitrostjo VI.The bracket-bearing bracket then preferably arrives at high speed in the initial waiting position, where it is ready to position the next pile. In some cases, the speed of travel of the pile is very high, sometimes resulting in a return velocity above the velocity of VI.

Sl. 3 je pogled od spredaj na transporter, ki je opremljen s pozicionirnim sistemom po izumu. Na sl. 3 je predstavljena pozicionirna naprava, ko sta naslona dvignjena. Transporter je sestavljen iz valjev 16, nameščenih na kolesih 17, ki so vgrajena v ustreznih oporah 18. Na enem od svojih koncev so valji 16 gnani s hitrostjo VI od pastorkovFIG. 3 is a front view of a conveyor equipped with a positioning system according to the invention. In FIG. 3 shows the positioning device when the backrests are raised. The conveyor consists of cylinders 16 mounted on wheels 17, which are mounted in suitable supports 18. At one end, the cylinders 16 are driven at a speed of VI by the stepchildren.

19. Ves transporter je zaščiten s pokrovom, fiksiranim na okvir 20, tako da so šipe vzdrževane na primerni temperaturi.19. The entire conveyor is protected by a cover fixed to the frame 20 so that the piles are maintained at a suitable temperature.

Pozicionirni sistem obsega nosilec 21, ki je razporejen nad cilindri 16 in vzporedno z njimi. Nosilec 21 je smotrno opremljen z dvema oporama, ki sta vgrajeni npr. s pomočjo drsnikov, pri čemer ti opori nista vidni na sl. 3. Na vsaki strani nosilca 21 so razporejene konzole 22, na katerih sta pritrjeni tirnici 23, 24, pri čemer tirnica 23 teče na kolesu 25. Tirnica 24, kije narejena s trikotnim delom, teče na kolesu 26, zasnovanem kot utorasto kolo, ki izvaja in zagotavlja vodilno funkcijo. Kolesi 25,26 sta pritrjeni na izsrednikih, ki ju premikata pnevmatski dvigalki 27.The positioning system comprises a support 21 arranged above and parallel to the cylinders 16. The carrier 21 is advantageously provided with two supports, e.g. by means of sliders, these supports being not visible in FIG. 3. Consoles 22 are arranged on each side of the bracket 21, on which the rails 23, 24 are attached, with the rail 23 running on the wheel 25. The rail 24 made with a triangular part runs on a wheel 26 designed as a grooved wheel, which performs and provides leadership function. Wheels 25,26 are mounted on the cranks driven by pneumatic hoists 27.

Fiksirne konzole 22 so nadalje pritrjene na vozičkih 28, ki se drsno gibljejo vzdolž osi, vzporedne z ravnino risbe, kar je rezultat tega, da jermen 29 vrti dvigalko, jermen pa je preko niza vračalnih jermenic speljan k osi motorja 30, fiksiranega k tlom preko nog 31.The retaining brackets 22 are further attached to carts 28 that slide sliding along an axis parallel to the plane of the drawing, as a result of the belt 29 rotating the lift and the belt via a series of return pulleys driven to the axis of the motor 30 fixed to the ground via nog 31.

Sl. 3 tudi kaže, da se da višino vozičkov 28 nastaviti s pomočjo premikalnih ročajev 32, s čimer je omogočeno regulirati razdaljo med naslonoma in valji 16 transporterja, kar je potrebno v zvezi z upoštevanjem različnosti debeline šip.FIG. 3 also shows that the height of the trolleys 28 can be adjusted by means of movable handles 32, thereby allowing the distance between the struts and the rollers 16 of the conveyor to be adjusted, which is necessary in order to take account of the difference in thickness of the piles.

Nosilec 21 se da s pridom dvigniti s pomočjo kavljev, pritrjenih na okvir 20, ko je le-ta dvignjen npr. za odpravo šip, blokiranih na transporterju zaradi problemov nekje niže na liniji, zlasti v oblikovalni postaji.The carrier 21 can be conveniently raised by means of hooks attached to the frame 20 when it is raised e.g. to eliminate piles blocked on the conveyor due to problems somewhere down the line, especially in the design station.

Pozicionirna naprava, kot jo predlaga izum, omogoča v veliki meri omejiti intenzivnost trenja med šipami in valji in s tem se izboljša optična kakovost šip ali oken. Ta naprava celo lahko deluje v postrojenju, kjer si šipe sledijo druga blizu druge, npr. kjer so razmaknjene za manj kot 50 cm pri hitrosti potovanja okoli 20 cm/s, kot je to slučaj z usločevalnim postrojenjem, kakršno je znano iz FR-A-2.549.465 in FR-A-2.604.992.The positioning device according to the invention allows to a great extent to limit the intensity of friction between piles and cylinders, thereby improving the optical quality of piles or windows. This device can even operate in a plant where the piles follow each other, e.g. where they are spaced less than 50 cm at a travel speed of about 20 cm / s, as is the case with the decision plant as known from FR-A-2,549,465 and FR-A-2,604,992.

A method of positioning a pile (1) traveling on a conveyor according to which a stop element (6, 7) is mounted on the pile line (1) to which the leading edge of the pile (1) is inserted at one end and which remains for a sufficiently long time in contact with the glass (1) so that the conveyor is able to divert the glass and continue moving the pile (1), characterized in that during the entire positioning period, the stopping means (6, 7) performs translational motion in parallel with the movement of the glass in the same direction as the latter. and at a speed lower than that of the conveyor.

Positioning process according to claim 1, characterized in that the velocity V2 of the stopping element (6,7) is kept constant by the rod (1) in contact with it.

3. Positioning process according to claim 1 or 2, characterized in that the stop element (6, 7) is moved before the pile (1) hits it, the acceleration phase being terminated when the stop element (6, 7) hits the end of the leading edge.

Positioning process according to one of the preceding claims, characterized in that, when the positioning is complete, the stop element (6,7) accelerates and receives a speed V2 'above the speed of the conveyor and then pulls back.

5. Positioning process according to claim 1, characterized in that the stop element (6, 7) follows the following sequence of speeds:

Waiting in the initial position with the stopping element (6, 7) pulled back, lowering the stopping element (6,7), accelerating the stopping element (6,7) at speed V2, translatomic motion at constant speed V2, acceleration at the end of positioning and pulling back the stopping element (6,7) and returning to the starting position.

Positioning process according to claim 5, characterized in that the velocity V2 is less than half the velocity VI of the conveyor.

7. A positioning device for a pile (1) traveling on a conveyor formed by a carrier (21) to which a stopping element (6, 7) is attached, supported on its end by a single rail (8) parallel to the axis (7). 2) conveyors, the rails being supported by trolleys (11) traveling on wheels (9,10), the movement of the trolleys (11) by rotating the screw (12) parallel to the axis (2) of the conveyor.

Positioning device according to claim 7, characterized in that the wheels are attached to the straighteners, which are moved by rotary lifts (14), which are preferably digitally controlled.

Positioning device according to claim 7 or 8, characterized in that the stopping element (6,7) is made of backrests fixed by sliders on the arms (5) attached to the carrier (4,21).
