Description

Opfindelsen angår et anlæg til at lakere hjulsættene på et skinnekøretøj, og som har mindst et lakeringskammer med et spor, der er farbar med de hjulsæt, der skal lakeres, og som er forsynet med en lakeringsrobot.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a system for painting the wheelsets on a rail vehicle, which has at least one paint chamber with a track that is passable with the wheelsets to be painted and which is equipped with a paint robot.

Forskellige køretøjers hjulsæt lakeres af lakeringsrobotter, hvorved påføringens ensartethed er af væsentlig betydning.The wheelsets of different vehicles are lacquered by lacquer robots, whereby the uniformity of the application is essential.

Fra DE 196 29 288 Al kendes et lakeringsanlæg til lakering af fælge på motorkøretøjer. Anlæggets holder er forsynet med mindst et par drivhjul, som går i friktionsfast indgreb med fælgenes omkreds, så de drejes under lakeringen.From DE 196 29 288 Al is known a coating system for painting rims on motor vehicles. The system holder is equipped with at least a pair of drive wheels which engage friction-tightly with the circumference of the rims so that they are rotated during the coating.

Fra DE 23 06 851 C3 kendes et lakeringsanlæg til KFZ-karosserier, som føres til påføringsstationen hængende på skinner. DE 196 49 538 Al viser en sædvanlig påføringsrobot til sådanne indretninger. DE 526 844 angiver et lakeringsanlæg som svarer til krav 1’s overbegreb.From DE 23 06 851 C3, a coating system for KFZ bodies is known, which is carried to the application station hanging on rails. DE 196 49 538 A1 discloses a conventional application robot for such devices. DE 526 844 specifies a paint system which corresponds to the concept of claim 1.

Der findes det problem ved brug af lakeringsrobotter, at hjulsættene er forholdsvis lange, og at industrirobotternes arme derfor er udformet med tilsvarende længde. Ved et arrangement, hvor lakeringsrobotten er placeret ved en side af lakeringskammeret, findes desuden det problem, at de kendte lakeringsanlægs akseltappe kommer forholdsvis tæt på denne side, så industrirobottens bevægelsesfrihed er begrænset. Endvidere er lakeringen af den indad-vendende side af hjulet i nærheden af sidevæggen, hvor lakeringsrobotten er placeret, problematisk ved de kendte anlæg.There is a problem with the use of paint robots, that the wheel sets are relatively long and that the arms of the industrial robots are therefore designed with a similar length. In addition, in an arrangement where the coating robot is located at one side of the coating chamber, there is the problem that the shaft pins of the known coating systems come relatively close to this side, so that the freedom of movement of the industrial robot is limited. Furthermore, the coating of the inward-facing side of the wheel in the vicinity of the sidewall where the coating robot is located is problematic at the known facilities.

Formålet med opfindelsen er at anvise et lakeringsanlæg af den indledningsvis nævnte art, som tager de svære rumforhold i lakeringskammeret i betragtning.The object of the invention is to provide a paint system of the kind mentioned initially, which takes into account the difficult room conditions in the paint chamber.

Denne opgave løses ifølge opfindelsen derved, at der i lakeringskammeret er anbragt et sporafsnit på en tallerken, der kan drejes mindst +/- 90° eller 270°, at det sporafsnit, der løber på tallerkenen, er afbrudt på midten, og at tallerkenen har et par drivhjul, der via sporafsnittets afbrydelse står i friktionsfast indgreb med hjulets slidbane eller hjulkrans, således at hjulsættet kan drejes overfor at blive lakeret af lakeringsrobotten.This task is solved according to the invention in that a groove section is placed on a plate that can be rotated at least +/- 90 ° or 270 °, that the groove section running on the plate is cut off in the middle and that the plate has a pair of drive wheels which, via the interruption of the track section, are in frictional engagement with the tread or wheel rim of the wheel, so that the wheelset can be turned over to be painted by the coating robot.

En foretrukket udførelsesform er kendetegnet ved, at lakeringsrobotten er anbragt i en sidevæg på lakeringskammeret, hvorved lakeringsrobottens krop er placeret uden for lakeringskammeret, og lakeringsrobottens styrbare arm er placeret inde i lakeringskammeret. Opfindelsen forklares nærmere nedenfor under henvisning til tegningen, hvor Fig. 1 viser, set fra siden, et lakeringskammer ifølge opfindelsen, og Figur 2 viser, set fra oven, lakeringskammeret med fjernede sidevægge.A preferred embodiment is characterized in that the lacquer robot is arranged in a side wall of the lacquer chamber, whereby the body of the lacquer robot is located outside the lacquer chamber and the controllable arm of the lacquer robot is located inside the lacquer chamber. The invention will be explained in more detail below with reference to the drawing, in which FIG. 1 is a side view of a paint chamber according to the invention, and Figure 2 is a top view of the paint chamber with removed side walls.

Lakeringskammeret består af et - ikke yderligere beskrevet - rensningskammer, et i føringsretningen for hjulsættet, der skal lakeres, bagved anbragt - ligeledes ikke yderligere beskrevet - tørrekammer, og et bagved anbragt lakeringskammer 12, hvorved de forskellige kamre er adskilt fra hinanden med døre, som kan lukkes.The lacquer chamber consists of a cleaning chamber - not further described - one in the direction of the wheelset to be painted, rearwardly - also not further described - drying chamber, and a rearwardly lacquering chamber 12, whereby the various chambers are separated from each other by doors which can be closed.

Lakeringskammeret 12 er forsynet med en tallerken 18, hvorpå der er anbragt et sporafsnit. Tallerkenen kan drejes +/- 90° eller 270° fra den position, hvor dens sporafsnit flugter med det øvrige spor.The lacquer chamber 12 is provided with a plate 18 on which is arranged a groove section. The plate can be rotated +/- 90 ° or 270 ° from the position where its track section aligns with the other track.

Det sporafsnit, der løber på tallerkenen 18, er afbrudt på midten. Tallerkenen 18 har desuden et par drivhjul 20, der via sporafsnittets afbrydelse står i friktionsfast indgreb med hjulets slidbane eller hjulkrans, således at hjulsættet 10 kan drejes for at blive lakeret af lakeringsrobotten.The track section running on plate 18 is cut off in the middle. The plate 18 additionally has a pair of drive wheels 20 which, via the interruption of the track section, are in frictional engagement with the wheel's tread or wheel rim, so that the wheelset 10 can be rotated to be painted by the coating robot.

For at lakere hjulsættet bliver hjulsættet, som er anbragt i lakeringskammerets midte, grebet af drivhjul parrene 20. Derefter følger en drejning af tallerkenen på + 90°, således at aksen på det hjulsæt 16, der skal lakeres, løber parallelt med sporet.To paint the wheel set, the wheel set located in the center of the paint chamber is gripped by the drive wheels pairs 20. Then a turn of the plate of + 90 ° follows, so that the axis of the wheel set 16 to be painted runs parallel to the track.

Lakeringsrobotten 16, hvis krop er placeret uden for lakeringskammeret, og hvis arm er placeret inde i lakeringskammeret 12, lakerer da i overensstemmelse med et program, der bestemmer armens bevægelse, det ene hjuls slidbane, akseltappen og den ene halvdel af akslen. For at tilvejebringe en ensartet påføring af lakken finder lakeringen sted under stadig drejning af hjulsættet, hvilket bevirkes af drivhjulene 20. Efter at den ene halvdel af hjulsættet er lakeret, følger en drejning af tallerkenen 18 på 180°, således at hjulsættets anden halvdel nu et tilgængelig for Lakeringsrobottens 16 arm, hvorefter lakeringen af den anden halvdel af hjulsættet finder sted under drejning af denne halvdel.The paint robot 16, whose body is located outside the paint chamber and whose arm is located inside the paint chamber 12, then paints according to a program that determines the movement of the arm, the one wheel tread, the shaft pin and one half of the shaft. In order to provide a uniform application of the varnish, the varnishing takes place while still rotating the wheelset, which is caused by the drive wheels 20. After one half of the wheelset is lacquered, a rotation of the plate 18 of 180 ° follows, so that the other half of the wheelset now available for the Laker Robot 16 arm, after which the lacquer of the other half of the wheelset takes place while rotating this half.

Derpå følger en drejning af tallerkenen 18 på yderligere 90°, så hjulene igen flugter med sporet, og hjulsættet kan føres ud.Then a turn of plate 18 is followed by a further 90 ° so that the wheels are flush with the track again and the wheelset can be extended.

Den her foreslåede udformning af et lakeringsanlægs lakeringskammer tillader en ensartet lakering også under svære rumlige forhold i lakeringskammeret, hvorved lakeringsrobottens arm kan udformes kortere end hjulsættet, hvilket især er af betydning, da lakeringsarmens stabilitet påvirkes negativt, såfremt den har en altfor stor længde.The design of a painting system's paint chamber here proposed allows uniform paintwork even in severe spatial conditions in the paint chamber, whereby the paint robot's arm can be designed shorter than the wheel set, which is especially important since the paint arm's stability is adversely affected if it has an excessive length.
