Procedure and device for the continuous production one simply or several times bent Glasbandes, in particular of building profile glass

The invention concerns a procedure and a device for the execution of the same for the continuous production einoder several times bent Glasbandes, in particular from Bauprofllglas, with or without Stahilisierungselementen, in particular such from wire or wire mesh. It is to be achieved by the invention that the assortment at glass pro EN extended, whose quality in particular regarding the dimensional accuracy, surface quality and optical characteristics improves as well as the work time necessary for the production are shortened and thus the manufacturing costs are lowered. It is already well-known to convert from a melting furnace continuously out-flowing frit in a rolling procedure by a pair of rollers to a flat Glasband of even strength and width to then form this in still ductile condition by bending mechanisms in several stages to the cross section of the strand profile which can be manufactured nnd in such a way manufactured Strangprof'd afterwards in a cooling furnace on ambient temperature to cool down. Further it is well-known to roll in for the improvement of the mechanical characteristics of the Strangprof'fles into the still ductile Glasband of wires or wire meshes. For the execution of a such procedure there are already different devices. Like that it is well-known to arrange itself behind the pair of rollers serving for the production of the Glasbandes lüntereinandergeschaltete, first flat, then the cross section which can be manufactured ever more approaching guidance supports or adjustable guide sheaves which transport equipment leading formed from roles by the cooling furnace follows. Further i t a device admits, with which between the pair of rollers and the cooling furnace figuration mechanisms are, which limit the Glasband in the figuration place over the entire profile cross section and from the interior profile producing, with Bandgesehwindigkeit moved for cores as well as from several producing the Außenprof'rI surrounding countryside-end deformation rollers exist, whose Oberflächengeschwindigkeit at all parts standing with the Glasband in contact essentially corresponds to the glass volume speed. These figuration elements can guiding devices be upstream, which prepare the shaping. With the application of a such procedure and the device to the Durchfährung of the same the glass up to the finished strand profile is formed by several successive rolling procedures. The glass cools ever more and its mouldability down diminishes. Easily, particularly by a too large roller speed, tensions in the glass can occur, to errors ferries making uselessly those to distortion, tears and others the Strangprof'fl. Particularly large difficulties result in the case of Strangprof'tlen reinforced by wire meshes. The temperature is still very high with rolling the wire mesh in into the Glasband, so that both form an as it were homogeneous unit. This however by the following rolling procedures to a large extent again is destroyed, since the wire mesh stretches itself in the comparison to the glass for only very little, in addition, thus the physical properties of a such strand profile is strongly down-reduced. It is well-known to roll for the favorable influence of the stretching procedure curved wire mesh in into the Glasband. A such measure increases however the total costs, without completely repairing the Mangd. For the achievement of the complete system thus the rolling speed permissible for the figuration of the cross section the extrusion press from the Glasband is decisive. Since this is relatively small however, and particularly with complicated profile cross sections of the far under Leistungst? ähigkeit the fusion aggregate lies, are the manufacturing costs for strand profiles from glass still much high and limit thereby its employment. It consisted now the task to develop a procedure and a device for the execution of the same which it makes possible, the rolling speed for the production of an endless Strangpro£tles of glass without occurrence of inadmissible tensions, dependent on the optimal achievement of the Sehmelzaggregates to arrange. According to invention this takes place by means of that directly before caliber of a pair of rollers by guidance in a collecting channel the caliber similar larger training is formed more exhibiting and an approximately constant pressure on the same exercising glass surplus and the cross section of the einoder several times bent G1asbandes is made directly of the Glasäbersehuß in a rolling procedure by the pair of rollers, whereby at the rollers the glass temperature is lowered directly on a temperature sufficient for the preservation of the manufactured more einoder several times bent Glasbandes, and after the rolling procedure einoder several times bent Glasband in still ductile condition is kept stable and arranged with arising deformations. By the procedure according to invention a substantial increase of the V¢alzgesehwindigkeit is and thus an important increase of the Arbeitsprodukfivität possible, since the strand profile is finished directly from the still liquid frit in a face procedure. In addition an extension of the assortment at Glasprufihn is possible when simultaneous improvement the quality, since without difficulties in each direction examinations and Pruißierungen of the Strangpro£ are possible hs. Hiedurch can be strongly extended the Anwandungsgebiet by Strangprofihn from glass and opened thus for new Verbraucherkreisen. In the device for the execution of the procedure the Sammdrinne, whose delta directly exhibits before the caliber this similar larger training and in that the inlet with a shutoff device provided and with the fusion aggregate of a Speiserinne connected for the admission of the glass surplus is intended, before the pair of rollers is arranged, and in or several calibers anfweisende pairs of direction rollers congruent in relation to the caliber of the pair of rollers are arranged after the pair of rollers. For the reaching of such training can be arranged in the delta Lenksteine. The Speiserinne is appropriately heatable trained. For the lowering of the downtimes with arising disturbances and above all also on conversion of production to other assortments are trained the collecting channel, the pair of rollers and the pairs of direction rollers than a replaceable unit. This can be exchanged then in shortest time against one outside of the complete system unit installed ready to be installed. It is further possible, at the collecting channel several pairs of rollers amuordnen. During a such device is for each strand profile places which can be manufactured only in each case one caliber form necessary, and devices admitted the number of necessary pairs of rollers including pairs of direction rollers substantially lower than with for the past procedures. The costs of the Gesamflage sink thereby substantially. By the small costs of the complete system and the higher productivity of the procedure according to invention when simultaneous improvement of the quality of the product and extension of the assortment it is possible, a better, to bring low-priced and the Effordemissen of the Verhraucherkreise generally corresponding assortment at strand profiles from glass on the market. On the basis the designs and a Ausführungsbeispides the Erfindnngsgegenstand is more near described. Show: Fig.1 a pattern of the complete system with an introduction device for a stabilization element, Fig.2 a cut by a collecting channel and a Walzeupaar, Fig.3 the delta of the Sammdrinne and the caliber of the pair of rollers, Fig.4 a cut by the collecting channel, a transverseformed pair of rollers and an appropriate Riehtwalzenpaar, Fig.5 the delta of the collecting channel for several pairs of rollers next to one another and the calibers the same and Fig.6 to 14 training forms of Profilquersehnitten. Between a fusion aggregate --2-- and a heated collecting channel --5-- is a feeder gutter --3-- arranged. The feeder gutter --3-- is with a shutoff device --4--provide, preferably in form of a slidegate valve. Subsequently, to the collecting channel --5-- is from a Oberwalze --9-- and a Unterwalze --10-- existing pair of rollers --8-- arranged. This points to the finished cross section of the strand profile which can be manufactured --12-- appropriate caliber --11-- up. The delta of the collecting channel --5-- is by Lenksteine --6-- so lined that it the caliber --11-- similar larger training possesses. It is therefore necessary, for each new caliber --11-- either a new Sammdrinne --5-- to plan, or a new Ausldeidung of the delta by Lenksteine --6-- to make. Oberund Unterwalze --9 and 10-- the pair of rollers --8-- in addition can be examined and prof'fliert. The example of a formed crosswise pair of rollers --8-- is represented in Fig.4. Before the pair of rollers --8-- one is from a supply role --16-- and an auxiliary role --17-- existing Einflthruagsvorfichtung flir a stabilization element --18-- arranged. Hiebei is favourable it, the Oberwalze --9-- shifted to the Unterwalze --10-- to arrange, as is represented in Fig.1. During the production of a Strangproflhs --12-- without insert of a stabilization element --18-- stand against it both rollers favourable-proves perpendicularly one above the other. Therefore it is appropriate to provide the pair of rollers with a Schwenkmeehanismus. The pair of rollers --8-- is connected with different Einriehtungen, which just like the slewing mechanism is not represented in the designs. Like that is the pair of rollers --8-- with, connected by a Temperaturregeleinriehtung steered Kühleinfichtung, those with the Oberwalze --9-- from a flow water cooling and with the Unterwalze --10-- of a splashing with Trockenvorriehtung to consist can. Further is an infinitely variable transmission for the pair of rollers, provided with a driving device --8-- planned, that with one preferably at the transition between fusion aggregate --2-- and feeder gutter --3-- arranged Regeleinriehtung is connected. The pair of rollers ---8--- a Transporteimächtung provided with its own Antfiebseinrichtung is subordinate. This exists from the pair of rollers --8-- to approximately to the beginning of a cooling furnace --15-- from or several, with the caliber --11-- the pair of rollers --8-- congruent calibers provided pair of direction rollers --13-- and afterwards from pinchrolls --14--. Between the pairs of direction rollers likewise Transportrolhn can --14-- arranged its. The individual members of the transport equipment, in particular the Riehtwalzenpaare --13-- can be provided with a steered cooling equipment. For the avoidance of Kaltlu£teinwirkungen on the material which can be processed it is appropriate to plan appropriate screens not represented in the designs. The collecting channel --5--, the pair of rollers --8-- and the Riehtwalzenpaare --13-- preferably form a replaceable unit. In Fig.5 an arrangement is shown, with afterwards to a collecting channel --5-- several pairs of rollers --8-- with same caliber --11-- are arranged. Hiebei is the delta of the collecting channel --5-- by Lenksteine --6-- so divided that before each pair of rollers --8-- the caliber --11-- similar larger training develops. It is naturally also possible and lies quite in the context of the Er8ndungsgedankens, afterwards to a Sammelrlnne --5-- several pairs of rollers --8-- with different caliber --11-- to arrange or at a fusion aggregate --2-- several pairs of rollers --8-- with in each case an own collecting channel --5-- to plan. Fiir the pairs of rollers --8-- is then transport equipment with according to arranged pairs of direction rollers --13-- and pinchrolls --14-- as well as preferably a common Ktthlofen --15-- planned. From the fusion aggregate --2-- the Glasschmelze flows --1-- by the feeder gutter --3-- the collecting channel --5-- too. There a Glasiiberschuß collects itself --7-- on, that by heating the collecting channel --5-- one keeps liquid. This glass surplus --7-- flows now the caliber --11-- the pair of rollers --8-- too. By the appropriate training of the delta of the collecting channel --5--, is the pressure of the Glasiibersehusses --7-- on all points of the caliber--11-- approximately evenly and concomitantly the glass river to these, flir the even training of the cross section of the Strangproflhs --12-- of substantial importance is. In a rolling procedure now the Strangprof'd becomes --12-- manufactured and at the same time the verarbdtete glass by the temperature of the roller surfaces Oberund Unterwalze --9 and 10-- on a temperature down-cooled, with that the form of the manufactured strand profile --12-- after going through the pair of rollers --8-- remains. A cooling on 700° to 900°C proved hiebei as favorable, since so no unfavorable influence on the structure of the glass is expenditure-practiced. The rollers of the pair of rollers --8-- before commencement of production to work temperature are warmed up and held during production by means of Kähhinrichtungen on this temperature. It is possible to support the cooling procedure during rolling by Lu£tdu. The rolling speed of the pair of rollers --8-- becomes dependent on the glass conditions of the Glasschmelze --1-- in the fusion aggregate --2-- by effect of the active glue proscription on the stepless transmission regularly. With production disturbances or conversions of production it is possible, the glass river of the fusion aggregate --1-- to the Sammdrinne --S-- by the shutoff device --4-- to interrupt up to the resumption of production. It is also possible, arrnierte strand profiles --12-- to manufacture. As stabilization elements --18-- hiebei wire or wire meshes is particularly used. The stabilization element --18-- rolls from the supply role --16-- off, arrives by the Hil£srolle --17-- led before the pair of rollers --8-- into the glass surplus --7-- and becomes then into the strand profile --12-- rolled in. Between glass and stabilization element as it were a homogeneous unit at the existing high temperature during the rolling procedure, which is also again not destroyed due to the unique figuration, forms. By the unique figuration it is further possible, also transverseformed strand profiles --12-- using an accordingly formed pair of rollers --8-- to manufacture. The strand profile --12-- runs now over the transport equipment to the Kählofen --15--. In this way is the strand profile --12-- relatively toughly, however by far yet does not solidify. It is however possible, by means of the pairs of direction rollers --13-- to keep stable $trangprofil and arrange with arising deformations. The strand profile --12-- with the fact it abgek'ählt itself however so that after entering the cooling furnace --15-- Pinchrolls --14-- Application to find know. The cooling furnace --15-- the strand profile leaves --12-- then with ambient temperature and can be supplied so to the further processing. With strand profiles without reinforcing the speed of the transport equipment is larger than those of the pair of rollers --8-- and with reinforced strand profiles somewhat smaller. However the speed differences are not so large that by it the strand profiles --12-- to be affected negatively, during with transverseformed Strangprof'den --12-- both speeds of equally large to be must, there the pairs of direction rollers 13-- otherwise would deform the rolled strand profile. With training of the Sammelrlnne --5-- the pair of rollers --8-- and the pair of avenging rollers --13-- as a replaceable unit it is possible to place and replace with disturbances or Produktäonsumstellungen against in production the present fast outside of the production course a such unit for the replacement or ready for the admission of a new production. Become several pairs of rollers --8-- with different caliber --11-- at a fusion aggregate --2-- arranged, it is possible, these according to their glass need with different Wa] zgeschwindigkeiten work to let. In Fig.6 to 14 producible strand profiles without and with Profillerungen in Längsund Querrichrung are represented by the descriptive procedure. The Zab_l of such strand profiles lets itself increase naturally at will. i
