A conveyor (3) is provided for transporting application objects (2) through the coating area. Independent claims are also included for the following: (A) Coating and treatment area for application objects; and (B) Coating system with many areas.

Description

Coating area and installation of coating with high appliances.

The present invention relates to an area of a cladding installation according to the preamble of the independent claims as well as to an installation of coating with areas of this type. In particular, it refers to varnishing areas or other areas of a facility for serial coating of application objects such as, in particular, bodies of motor vehicles or their annexed parts by using robots, including varnishing robots or other application, other manipulators, such as for example additional devices, and / or handling robots, such as by example door openers and bonnets.

In conventional varnish booths for motor vehicle bodies with robots their lanes guided are usually mounted laterally on the floor of the cabin. For different reasons it may be more appropriate, however, the arrangement of robot guide rails above the conveyor or even above the bodies for example because there they affect less the view through the wall side of the cabin and accessibility to the bodies or other application objects, and / or because the robots arranged elevated have a corresponding freedom of movement improved, and / or because the guide rails arranged elevated are dirtied less by Overspray, which is removed down by the usual air flow in the cabins. In addition, high mounted robots can have the advantage that less disturb the flow of air flowing from the roof of the cab down, along the sides of the body, towards the floor of the cabin that the robots that are on the floor next to the body, which narrow the air path directly next to the body, which can lead to a unwanted increase in the speed of the current.

In a varnish installation, known for the WO 2004/037430 A1, there are, in each case, several varnishing robots on two parallel guide rails the which, meanwhile, are mounted on a chassis arranged in the cabin interior space, with four support legs connected each other by crossbars, similar to known portal robot constructions.

From EP 1 263 535 B1 it is already known a generic varnish zone in a varnish booth for bodies of motor vehicles with air supply through from the upper roof wall and in each case two control zones mobiles arranged on the side walls vertically one above on the other, with robot guide rails, arranged by above the conveyor, in modular side wall elements Prefabricated cabin. The support structures of the Guiding rails are, unlike in the frame according to the WO 2004/037430 A1, separated from each other in space inside the cabin, therefore avoid their crossbars in the cabin interior space and possible problems regarding The mechanical strength of the known chassis. On the floor of this known varnishing booth, which is formed as usual by a lattice construction for the withdrawal of the current from vertical air, are mounted, below the guide rails arranged high, along the lower control area, rails Additional guidance for other robots, in the case of Bottom-level robots of varnishing robots and robots from the top of door openers and bonnets.

EP 0 745 429 A1 discloses some varnish booths for auto vehicle bodies with robot guide rails mounted on top of others on the walls of the booths and with several varnishing areas arranged, some after others, along the transport route of the conveyor.

Document DE 203 13 854 U1 discloses a Coating area with a body varnishing booth of motor vehicles, whose side walls run tilted up with increase in width reduction of the interior space. In this way, the displacement effect of bodies that are transported to through the cabin, whereby the cross section of circulation that is available free for air flow varies with less intensity depending on the height inside of the cabin.

In known varnishing areas with rails of guided of robots located elevated the lateral walls of the varnishing booth run from its upper roof wall, perpendicularly down, toward the ground plane. Given the the varnishing booth, including walkable control areas, should not be too wide, with a view to the costs of construction and investment, here are disadvantages of principle of the known varnishing areas. On the one hand, space Available for control areas is undesirably narrow. On the other hand, they would be unwantedly narrowed, in case of a given total width and an increase in the control zones, the paths for the air flow flowing in the cabin from The roof wall down.

Another problem is the necessary support of the elevated arranged guide rails that naturally you can achieve with greater difficulty than in guide lanes in the cabin floor. A sufficient strength of rails of guided mounted on a cabin wall above the conveyor, especially without its own transversal pillar at the height of these Guiding lanes, could be achieved so far with a undesirably large constructive complexity for walls correspondingly resistant sides.

The invention poses the problem of creation of a coating area or other type of a siding installation or an installation with several of these areas that are distinguished by a good use of space for the best possible air circulation and costs Low construction.

This problem is solved by characteristics of the claims.

According to a first aspect of the invention, a coating area has, in one or preferably in both sides of the transport route, at the height of the lanes of guided by elevated robots, a superior control zone passable, which is separated from the interior space of the area cladding by inclined side walls, thereby the interior space in this area becomes increasingly narrow at move up This forms, on the outer side of the sloping side walls, a space correspondingly width of the passable control zone, which can be used both for control facilities of the robot that found in the elevated guide rail as well as for the personnel who observe the coating process and for jobs maintenance. An essential advantage of the provision of control facilities in the vicinity of controlled robots for them they are at the same time the hose connections and correspondingly short driving.

At the same time it increases, thanks to the walls inclined sides, the cross section of circulation of the downward facing area, which is available for air circulation, which can be compensated to a certain extent corresponding the obstruction of air circulation by robots and circulation speeds vary with less intensity within the coating area than on the walls which until now were vertical. It turns out, for example, in a varnishing booth or a varnishing area for bodyworks of motor vehicles, an optimal air distribution also when the side walls run perpendicularly next to the body. An air circulation too strong next to the bodies or other application objects would drive, for example by dragging the coating material to be apply, reduce application performance.

According to the invention, the side walls have inclined travel only in the upper control zone passable while in the lower control zone passable, that is on the ground (typically covered by grid) of the lining area may run preferably, up to the upper edge of the objects of application, vertically upwards, for example to the zone of superior control. In this way, a total width is avoided undesirably large of the coating area in the area of the ground.

When there is only one guide rail of robots preferably raised on both sides of the conveyor, the Walkable lower control zone can be used, so minus one of the sides of the conveyor, for example for the observation of the coating process without hindrance to the vision for robots as well as for maintenance work, etc. However, it is also possible to mount on the ground in the area of lining or near the floor plane, on the wall side of the coating area, in one or preferably in both sides of the conveyor, other robot guide rails additional. The guide rails can be arranged, on each side of the coating area, at such a distance on top of others, that the corresponding robots can pass one next to each other in the parallel longitudinal direction with respect to the transport route However, more than two guide rails on one or each side, especially at heights different, that is to say in three or more distanced planes vertically with each other. For the distribution of in each case several robots on the guide rails, e.g. including robots varnishing and handling, there are especially possibilities described in documents DE 10 2004 030858 and DE 10 2004 056493 (EP 1 609 532 A1). In addition, it is possible to mount, on one or both sides of the coating area and the conveyor, one or various arrangements of guide rails, arranged at a distance each other, which may contain in each case more than one lane and that they can be built in such a way that on different lanes, spatially displaced from each other, from one and the same arrangement of guide rails, robots can pass movable next to each other in the parallel direction with respect to the transport path of the conveyor.

The lanes mentioned in relation to the This application can also be used advantageously for robots that can move on them for devices additional which, which may exist in a way additional to spray application robots (applicators) and / or handling robots (manipulators). Examples of additional devices are processing devices discretionary including mobile dryers, which may irradiate, in a known manner, the application objects for its drying with IR or UV radiation, as well as cleaning devices and, especially, also probes and measuring devices, which are known and usual itself for measuring results of coating and layer quality characteristics such as layer thicknesses, "wave scan", color tone, brightness, brightness, etc., and for the determination of errors of coating. Measurements can take place online, too for online quality measurement with error correction in your automatic case for following application objects, for example according to EP 0 874 213 B1 or EP 1 176 388 A2. The devices Additional can be found in a booth liner or also in a separate repair or control area, being able to be arranged then also without application robot or opener of doors or similar on the mentioned guide rails. The Additional devices may be mounted properly in own robots or also robots that serve universally as a pillar of different devices, such as for example sprayers, dryers, measuring systems, etc. When the Additional appliances are in a coating area, it can move on the rails of the application robots and / or handling provided there or, instead, on rails own, which can be displaced in height with respect to to the lanes of the application or handling robots.

The concept of "robot" used in the this memory must be understood in the most general sense of a Multi-axis automaton that can be freely programmed, preferably in a constructive way with an angled arm minus six rotary axes (three main axes and three axes of hand), being able to move the base body of the axes of consecutive movement as skate on one of the lanes here considered, similar to the accompaniment axis (axis 7) of conventional or similar varnishing robots. However it is also possible to mount, on a common base body, movable as a skate on one and the same lane, at least two robot constructions with for example in each case two or three axes main which, depending on the application case, may have, similar to the robots that can move through separated on the same lane or separate lanes, the same or different functions (coating, handling, mediation, etc.).

As explained above, it they need, for the assembly of the guide rails that found above the conveyor and, when appropriate, by above the upper edges of the bodies or others application objects, for several robots that work next to each other, special support structures which until now they were carried out either by means of the constructions of frame arranged in the coating or handling area or by proper formation of the side walls themselves. According to another aspect of the invention, they are provided by opposite, on at least one and preferably the two walls sides of the coating area or the control zone or repair, support structures, arranged and connected preferably fixedly with them, which can be supported with supporting elements, which extend transversely with with respect to the transport path of the conveyor, for example above or below the floor of the area or also on the ceiling wall, so that the side walls themselves do not have to be made carrier function charge and may be formed in a manner correspondingly simple and, for example for observation of the coating process, largely also transparent in the lower zone. These support elements don't have to be for therefore an integral part of the side wall itself, but may be away from the side wall and / or extend, separating from the side wall, transversely with respect to the transport path (preferably in a parallel direction to the ground plane).

On the other hand, support structures do not they have preferably (unlike the crossbars of the portal construction according to WO 2004/037430 mentioned at the beginning) supporting elements, which extend on the side top of application objects such as vehicle bodies cars but also below the roof wall through of interior space of the coating area and disturbing the vertical air circulation of the cabin and / or that could get dirty Application objects because of color particles or other kind of sticking to them and letting go again.

It may be especially suitable when you are support structures are constructively combined with the carrier or reinforcement elements of the separation walls ("Silhouettes") per se usual and necessary at the ends of entrance and / or exit of the individual coating areas. The purpose of these separation walls, arranged transversely with respect to the transport path, you can consist, for example, of insulating, several coating areas arranged one after another in a varnishing booth, with a different air economy in each case, for example an area for electrostatic application with rotating sprayers of one zone for air sprayers, thanks to the need different air velocities, having to be prevented in the as much as possible the mixture of air and circulations transversal between the zones. In addition, the transverse walls they have security functions for the protection of people.

One possibility is, for example, in hold these separation walls, arranged transversely with respect to the transport route, directly at support structures for robot guide rails high, which eliminates the complexity for fasteners typical of the separation walls. In particular, it can serve, however, a reinforcement structure for the guide rails of robots The support and support structures of the rails they can therefore be an integral integral part of a reinforcement of the separation walls or, on the contrary, the reinforcements of the separation walls can be an integral integral part of the support and support structures of the guide rails.

Application objects can be transported, through the areas considered, in operation  of continuous passage with robots that, as a rule, move along with them along the transport route or, instead of this, in cyclic operation in which the object is in rest during processing.

The invention is explained in greater detail to from the exemplary embodiments represented in the drawing in a broadly schematic and simplified way. At He drew:

For the same elements or those that are correspond are used, in the following, the same numbers of reference, also for different embodiments.

The lining area 1 for bodies of motor vehicles 2, shown in Fig. 1, may form a part of a varnishing booth. The areas described and represented herein and in what follows may be arranged however also, eventually, inside a cabin wider. The bodies can be passed through the area of coating 1 on a conventional floor conveyor 3 (comp. Fig. 3, not shown in Fig. 1) along a defined transport route, for example, by means of lanes 4 (Fig. 3). The coating area is limited by above by a horizontal roof wall 5, on both sides by 6 or 6 'side walls arranged parallel to the transport route, down the ground 7 horizontal and in the inlet and / or outlet ends by separation walls 8 or 8 'arranged transversely with respect to the path of transport. For example, in the varnishing booth you can connect, on the outer sides of the separation walls 8 and / or 8 ', along the transport route, other areas of similar or different coatings. In usual way it is conducts, during operation, an air circulation, directed down essentially vertically, through the coating zone 1 which, for example, can be introduced through the ceiling wall, equipped with this purpose with steps or a separate aeration installation, and can exit, for example, through the ground 7 formed as a construction Lattice The separation walls 8 and 8 'are introduced, sealing tightly between the wall elements contiguous, that is especially the side walls 6 and 6 'and, at if possible, also sealed between the ceiling wall 5 and the floor 7, in order to prevent air mixing or circulation cross-sections especially between contiguous areas with an economy of different air on both sides of the separation wall 8 or 8 ' correspondent. The openings 9 in the separation walls 8 u 8 'for bodies 2 on conveyor 3 can be closed by This motif during coating. In addition, they can be found on the side walls 6, 6 'and / or the separation walls 8, 8 'doors that can be closed (not shown) for staff of service, for example in a frame construction preferably metallic on one or both sides of the wall of separation 8, as depicted in 43 in the example of embodiment of Fig. 4, described below. Thanks to that there are advantages over safety such as the security of transit with the simultaneous creation of escape routes.

According to the representation, for example approximately halfway up the side walls 6, 6 'and preferably above the upper sides of the bodies 2, are arranged in the side walls, in the interior space of the lining zone 1, in each case 10 or 10 'guide rail arrangements for 11 robots. robots 11 may be equipped with conventional sprayers or other applicators for coating material. As structure of support for the guide rails serve, in the example represented, vertical 12 pillars, which are anchored in suspension, on or next to the ceiling wall 5, with elements of support 13 located horizontally transversely with respect to to the transport route, and which carry the 10 or 10 'guide rail arrangements with support elements 14 lower, also located horizontally transversely. Pillars 12 are located on the side of the provisions of 10 or 10 'guide rails, away from interior space in the area of coating 1, and of the corresponding side wall 6 or 6 '. The ceiling wall 5 can be, in this example, an integral part of roof construction made for example from concrete, of a larger space, in which the area of lining 1.

The separation walls 8 and 8 'are fixedly connected at least to the side walls 6 and 6 'and may also be subject with its frame 19 directly to the supporting structures of the lane arrangements of guided 10 and 10 '.

The lining zone 1 has on its side, away from its interior space, from the side walls 6 and 6 ', on the ground 7 that extends there, in each case, a first control zone 15 or 15 'passable for the personnel of service 16. In addition, it is preferably provided on both sides of the coating zone 1, above the first zone of 16 or 16 'control, on the upper side of the constructions that contain the provisions of 10 or 10 'guide rails, also on the outer side of the side walls 6 or 6 ', in each case a second control zone 17 or 17 'passable for the service personnel 16. At least in control areas 17 and 17 'upper control cabinets can be found (no represented) and other control and supply facilities for the robots 11.

In the example represented the area of siding 1 contains only the rail layouts of  guided by high 10 and 10 'robots, although there is the possibility to mount on the floor 7, between the bodies 2 and the walls 6 or 6 'sides, on one or both sides, in parallel with respect to the guide rails, provisions 10 and 10 'in each case another guide rail for additional robots.

The side walls 6 and 6 'run, according to the representation, in the control zone 15 or 15 'lower, starting from floor 7, perpendicularly up to constructions containing the lane arrangements of guided 10 or 10 'and, consequently, in the example shown, up to a height above the bodies 2. Part 18 of the side walls 6 and 6 ', which extends into the control zone 17 or 17 'upper passable, which runs upwards from the robot guide rails, on the other hand inclined obliquely inward, according to the representation, so that the interior space of the lining zone 1 is constantly narrower in these control zones. The inclined path of the side walls 6 and 6 'can be converted according to the representation, before reaching the ceiling wall 5, again in a vertical part, which is anyway in the vertical direction shorter than the inclined part 18. The entrance openings of air lining area are in the area of the roof wall 5 located between the upper end of the walls 6 and 6 'sides.

The lower vertical parts of the walls lateral 6 and / or 6 'can be, for example, so high (approx. 2 m) that there can be mounted precisely doors for the staff of service 16.

The side walls 6 and 6 'do not have to have themselves bearer function for other integral parts of the coating area and can be made, at least in an essential part of a transparent work material as glass, in order to make possible the view of staff 16 in the interior space. The separation walls 8 and 8 'can be also transparent.

In the case of floor 7, represented only schematically, it can be a lower construction or carrier supported, on the other hand (not represented) on supports separate, on or under which the provisions of electrical, pneumatic and supply lines for the area considered, for example, including pipes annular for the supply of color in the case of a cabin varnished For access to this supply area may be provided, for example floor covers 7.

Especially suitable can be a structure modular areas described here, which can be mounted previously, in whole or at least partially, in the dependencies of the manufacturer of the installation and be transported in this state until the operator of the installation, so that The advantages are explained, among others, in EP 0 349 177 A. During the modification of older facilities previously existing modules of this type can be placed, assembled beforehand, with the help of the constructions lower and carrier mentioned above, as soil on special foundations

The coating area 21 according to Fig. 2 corresponds extensively to the exemplary embodiment according to Fig. 1, so that with respect to the lane arrangements of guided 10 with the robots 11, the side walls 6 with the parts 18 inclined, from control zones 15 and 17 and, with respect to Separation walls 8 a new description is not necessary. The guidance lanes are not suspended here however in a resistant roof wall, as in Fig. 1, but they are mounted on vertical carrier supports 22. Braces carriers can be supported, for their part, with supporting elements horizontal cross sections, indicated only schematically in 24, on the ground 7 that is assumed here as resistant. Under the floor 7 there can also be elements of adequate cross support. The roof wall 25 permeable to air from the lining area 21 may be formed as in conventional varnish booths.

The coating area 31 represented in Fig. 3 may correspond, in relation to the controllable control areas and the partly inclined side walls, to the examples of embodiments described above, although this is not represented here. The construction according to Fig. 3 is suitable, however, also for a coating area without these characteristics. There is a coincidence with Fig. 1 and Fig. 2 in any case with regard to the conveyor 3 and, where appropriate, as regards the arrangements of guide rails 10 for robots 11 arranged above the bodies 2. The conveyor 3 shown in Fig. 3 with rails 4 for the bodies 2 can also be used in the embodiments according to Fig. 1 and
Fig. 2.

Unlike the examples of ways of embodiment described above, especially the support structures for guide rail arrangements 10 elevated. These support structures consist, essentially, of frame constructions 33, for example of the rectangular shape represented, with two carrier supports 32 vertically connected by transverse support elements 34 upper and lower. The frame 33 constructions consist of each case, in this example, of a vertically placed plane transverse with respect to transport rails 4 on the side, oriented towards the conveyor 3, of the provisions of guide rails 10 of the robots 11 and, with it, on the side exterior of the side walls 36 on a part of the floor 37. According to the representation may be arranged, below each of the ends of the guide rail arrangements 10, adjacent to the outer side of the vertical side wall 36 in this place, such a framework that is supported by the support element transverse 34 lower on the floor part 37 and support in its upper transverse support element rail layout of guidance 10. There may also be (not shown) other frames of this type or other supports. The two frame 33 constructions, which serve as support structures for the guide rails of robots, at the entrance and exit ends of the coating area 31, may preferably be connected in the vicinity of the ground plane and, properly, under the conveyor 3 by means of a crossbar 35. The crossbars of this type for the frame constructions 33 can also be arranged at height  of the guide rail arrangements 10.

The separation walls 8, provided in the inlet and outlet ends of the lining area 31 can be properly inserted between the constructions of frame 33 contiguous parallel to them which can serve in This case, in addition to its function as a support structure for robot guidance lanes, at the same time as construction reinforcement or separation wall frame and, where appropriate, the crossbars 35 of the frame constructions 33.

The coating area 41 represented in the Fig. 4 is a modification of the exemplary embodiment according to Fig. 3, from which it differs essentially only in that frames 43, which serve as a support structure for guide lane arrangements 10 of the robots, which in principle match with frame construction 33, I don't know extend on the side of the robot driving lanes away from the conveyor 3 but, according to the representation, They are arranged on the side facing the conveyor. Guide rails 10 are located here, according to the representation, on an extension, oriented horizontally outward from the upper transverse support elements 44 of the frames 43. The separation wall 48 is inserted here also sealing tightly between frame 43, which serves as reinforcement of the separation wall, that is the structures of support of the guides of guides of robots. The constructions frame 43 (or 33 in Fig. 3) may contain wall elements transparent or others.

The examples of embodiments described they can be modified in different ways, especially also in regards to lane arrangements. For example, it may be appropriate to arrange lanes that run, inside or outside of the coating area (or a control or repair zone in the case of the additional devices mentioned), before and / or after of the processing area, for example perpendicularly (Y direction) with respect to the parallel running rails with respect to the transport address (address X) of the application objects, in the plane or planes of the X-rails These cross rails can be also arranged above the application objects and are preferably connected in this way with the one or more lane (s) -X corresponding in it flat, so that the robots in question can change the X-lane to transverse lane and vice versa and / or between the X-lanes on opposite sides of the path of transport, for example in a manner known per se in the art Of transport.

The other possibility of modification consists of install, instead of linear rail arrangements described, guide rails with, in particular, a route horizontal circular or semicircular or, for example, oval curved, preferably with respect to the transport path or symmetric and preferably closed with respect to a vertical axis. Here an arrangement of lanes above application objects such as, for example motor vehicle bodies.

The arrangements of rails modified in this way may also be suitable, in the context of the claims, in installations in which essential features of the invention described herein are not realized, especially with respect to the inclined path of the side walls or of the special support structure and its support elements, although they can be combined, on the other hand, also with any of the remaining features of the described invention. The arrangements of XY rails with the possibility of changing the robots as well as the arrangements of rails with curved or circular paths are suitable, in particular, also for mounting suspended in a coating, control or repair area. Suspended mounting, for example on a car roof or on a sloping side wall of a car can be carried out, in particular, in the manner described in the application
EP 06 111 359.3.

The provision of additional devices on mentioned lanes can be combined, within the framework of claims, with each of the remaining features described in this application, since it has advantages independent such as a good use of space and reduction of constructive complexity in an installation of coating and, in case of use of common robots for different devices, also a reduction in the complexity of machines and control.

In general, the combination of each one is possible of the characteristics described in this application with one or several of the other characteristics described in the framework of the claims, and advantageous, depending on the embodiment.

The described areas may be arranged, a behind another, in an inline lining installation conventional. They can be arranged, however, also parallel to each other when the transport route of the application objects branches into several parallel branches, in which in each case one of the areas of processing, as described in patent application DE 10 2006 022 335.

In all examples of embodiments of the invention with coating areas the guide rails of robots should be structured and preferably arranged such that the rails and robots do not influence or do not at least essentially about the air circulation in the cabin. This is achieved by a narrow constructive form. and / or by positioning the lane on the outside, especially above the varnishing area.
