Description

BACKGROUND OF THE INVENTION 1. Field of the invention

The invention relates to a system for treating objects such as vehicle bodies and / or vehicle components with a plurality of treatment modules.

The invention also relates to a treatment module for the treatment of objects such as vehicle bodies and / or vehicle attachment parts and a method for treating objects such as vehicle bodies and / or vehicle attachment parts.

2. Description of the Related Art

Equipment for the treatment of objects are used, for example, as paint shops or as drying systems in vehicle construction, for example, for vehicle bodies or vehicle attachment parts. Vehicle attachment parts may be, for example, bumpers, exterior mirror covers, wheels, etc.

Typically, such systems are divided according to the necessary for a painting or drying treatment steps in individual areas, which passes through the object to be treated in order. In such a "road" or "line", the components to be treated are usually transported along a contiguous transport path through the treatment plant and the individual treatment stations.

Especially in the coating and Lackierbereich the objects to be treated are usually promoted in continuous continuous operation. The objects to be treated are transported on a conveyor unit continuously within the processing line along a fixed path through the individual processing areas. Alternatively, such a coating or painting plant also work clocked. This is also called stop-and-go. In such a case they are too also during the entire treatment in / on the conveyor unit, but are essentially silent during the treatment at the respective station and are promoted between the individual treatment steps from one station to the next.

In both cases, it is customary for the objects to be treated to be applied at the beginning of a treatment to a workpiece carrier, for example a so-called skid, which transports the object (s) to be treated to the individual treatment stations. As a rule, the objects to be treated do not leave the workpiece carrier for the treatment or are returned to the workpiece carrier after the treatment step. A conveyor system connecting the individual treatment stations ensures that the objects to be treated reach each treatment station in accordance with a continuous predetermined sequence by means of such a workpiece carrier.

For this purpose, a continuous conveyor system is usually provided. In principle, a single workpiece carrier can pass through the treatment system from start to finish and thus also each individual treatment station.

A disadvantage of the mentioned treatment systems is that subsequent capacity extensions are possible only with basic modifications of the entire treatment plant. This weighs particularly hard for smaller systems, for which from the outset only a small floor area is provided. On the part of the plant operators, therefore, there is an increasing desire, especially for smaller treatment plants, for example, for vehicle components with low available floor space to achieve a compact system structure, which allows even after the initial construction extensions in the capacity of the system without a fundamental conversion.

In this context, modularly constructed systems are known in the prior art which promise a certain flexibility in the construction of paint shops. By way of example in this connection is the international patent application with the publication number WO 2009/018841 A1 directed. There, a painting system constructed from module groups is described, with the workpieces individual processing stations go through one after the other. A disadvantage of this approach is that increases the overall length for an increase in the capacity of the system and thus the entire layout of the system must be redesigned.

It is an object of the present invention to provide a plant, a treatment module and a method of treating articles which allows a simple change in the total capacity of the plant.

SUMMARY OF THE INVENTION

The object is achieved by a system for the treatment of objects such as vehicle bodies and / or vehicle attachment parts according to independent claim 1.

The system according to the invention has a plurality of treatment modules. Each treatment module has a treatment zone, a conveyor system for conveying a workpiece carrier along a path within the treatment module and for the conveyor system at least one receiving point for receiving a workpiece carrier and at least one delivery point for dispensing a workpiece carrier. The conveyor system is adapted to receive a workpiece carrier at the receiving location, to convey into the treatment zone and to convey it to the delivery point.

The delivery point of a first treatment module and a receiving point of a second treatment module are designed such that the delivery point of the first treatment module can cooperate as intended with the receiving point of the second treatment module, that a workpiece carrier can be transferred from the first treatment module to the second treatment module.

Thus, each treatment module has its own conveyor system. By dividing the conveyor of the system in accordance with the treatment modules separate, the respective treatment module associated conveyor systems, the previous concept is abandoned. There is no continuous conveyor system that could feed a workpiece carrier through all treatment modules. Rather, from treatment module to treatment module a transfer of a workpiece carrier with an object to be treated instead of. Within the treatment module, the workpiece carrier can be conveyed from the receiving location to the treatment zone and from the treatment zone to the delivery location. The resulting transfer points are also interfaces within the system and thus allow a total of a modular design of the system. This means a significant improvement in terms of flexibility in design of the system and facilitates a subsequent change in the system, such as an increase in plant capacity.

The individual treatment modules are constructed in terms of their receiving point and their delivery point so that receiving point and delivery point are compatible. Thus, a receiving location of a first treatment module can cooperate as intended with a delivery location of a second treatment module.

Overall, this results in a completely modular design of the entire system. The interfaces of the conveyor system allow easy replacement of a treatment module. This may be used, for example, to replace it with a larger capacity in a desire to increase the capacity of the treatment module. The conveyor technology integrated within the treatment module does not require a larger capacity treatment module to have a greater length at the same time. Rather, the larger capacity can also be reflected in a treatment zone which is widened perpendicular to the general conveying direction. At the same time, the overall system can also be easily expanded by the modularity, in that only one further treatment module is attached to an already existing interface, such as, for example, a receiving station or a delivery point.

The separate delivery system of a treatment module also makes it possible to easily expand a single treatment module in terms of its capacity. Thus, due to the possibility that a workpiece carrier from the receiving location to the treatment zone is conveyed, simply the capacity of the treatment zone and thus the capacity of the treatment module can be extended without the module or larger parts of the system would have to be replaced.

In an advantageous embodiment of the invention can be provided that each treatment module has its own conveyor drive. The conveyor drive can be controlled individually. In this way, the overall control of the system can be adapted on a modular basis.

Advantageously, it can be provided that each receiving point is compatible with each delivery point, so that each treatment module can be combined with another treatment module. This allows a particularly easy combinability of the treatment modules with each other.

An advantageous embodiment of the system provides that the treatment zone of a treatment module comprises a plurality of treatment units. The division of the treatment zone into treatment units facilitates the already mentioned adaptation of the capacity of the treatment zone of a treatment module. For an increase in capacity, the number of treatment units per treatment module can be increased and reduced accordingly for a reduction in capacity. Due to the separate conveyor system, this does not require any adaptation of the conveyor systems in other treatment modules or a - not present anyway - overall conveyor system.

In a specific embodiment of the system can be provided that the treatment units are similar and / or arranged side by side and / or one above the other. The treatment units may, for example, be similar in terms of their function and / or their dimensions and / or their construction. Similar treatment units within the treatment zone of a treatment module reduce the manufacturing costs of the individual treatment units and facilitate an increase or decrease in the number of treatment units per treatment module or an exchange of individual treatment units. In the case of an increased capacity requirement, further similar treatment units can be added in a simple manner; if the capacity requirement is permanently lower, the identical treatment units can simply be dismantled and, if appropriate, otherwise utilized.

An arrangement of the treatment units next to each other within the treatment zone of a treatment module, for example, directly adjacent to each other, represents a conveying technology easy to implement embodiment. An arrangement of treatment units on top of each other saves installation area for the treatment module and thus also for the entire system. This is particularly interesting for a subsequent expansion of the capacity of a treatment module or for a particularly short footprint for the entire system.

An embodiment of the system provides that the treatment units perform the function of a vaporization zone, a dryer, a cooling zone or a general residence time. Thus, functions that require a certain residence time within a plant can be realized over a corresponding number of treatment units within the respective treatment module. In particular, a number of treatment units corresponding to the respective residence time per treatment module or treatment zone can be provided.

In this context, it may be advantageous if the treatment units can be charged by means of the conveyor system. For this purpose, the conveyor system, for example, a turntable, a lift table, a combined rotary rotary table or similar device to achieve the required for the feeding of a treatment unit alignment of the workpiece carrier. For example, the treatment units may be designed for the loading or the loading in such a way that, as a result of an inclination or depression of a level present in the treatment unit, the workpiece carrier can slide without drive into the treatment unit. The inclination can be done for example pneumatically or electrically. For the discharge can be reversed by adjusting the plane in the other direction or raised. Alternatively, a transfer of the workpiece carrier to the treatment unit in push / pull operation can take place. The treatment unit itself can be designed, for example, as a shelf with compartments or with drawers.

In one embodiment of the system can be provided that the conveyor system has a conveyor unit for receiving and moving a workpiece carrier. This allows a particularly simple transfer of a workpiece carrier. In particular, when transferring a workpiece carrier to a treatment unit, a telescopic conveyor can be used.

With regard to the receiving point and the delivery point of a treatment module can be provided that receiving location and delivery point are identical. This may mean that there is only a single transfer point on the treatment module, which acts both as a receiving site and as a delivery point. The receiving point and the delivery point may alternatively be arranged, for example, on opposite sides of a treatment module and thus enable a straight-line continuous operation by the treatment module. Alternatively, receiving location and delivery location can be arranged on adjacent sides of a treatment module. This allows for a rectangular basic structure of a treatment module, a deflection of the workpiece support path relative to the entire system seen by 90 °. Furthermore, alternatively, the receiving location and delivery location can be arranged on the same side of a treatment module. This allows for a rectangular basic structure of a treatment module, a deflection of the workpiece support path relative to the entire system seen by 180 °.

Further embodiments of the system are specified in the remaining subclaims.

The object is also achieved by a treatment module for the treatment of objects such as vehicle bodies and / or vehicle attachment parts. The treatment module according to the invention has a treatment zone, a conveyor system for conveying a workpiece carrier along a path within the treatment module and for the conveyor system a receiving point for receiving a workpiece carrier and a delivery point for dispensing a workpiece carrier. The conveyor system is adapted to receive a workpiece carrier at the receiving location, to promote the workpiece carrier in the treatment zone of the treatment module and to convey the workpiece carrier to the delivery point.

The receiving point and delivery point of the treatment module are set up so that the receiving point of the treatment module can cooperate as intended with a delivery point of another similar treatment module and / or the delivery point of the treatment module with a receiving point of another similar treatment module. Admission point and delivery point of a treatment module are thus compatible with each other. The receiving point of a treatment module can be combined with the delivery point of another treatment module so that a transfer of a workpiece carrier from one treatment module to another treatment module is possible without requiring a further transfer functionality, for example in the form of a transfer robot. This allows the advantages of a particularly flexible modularity of a treatment plant constructed from such treatment modules already described above.

In a treatment module according to the invention it can be provided that the treatment module has one or more interfaces. For example, an interface can simultaneously form the receiving point and the delivery point, but it is also possible to provide several interfaces with different functions. In addition to the transfer function for one or more workpiece carriers, an interface can also offer a simplified interface for media such as, for example, high-performance electrics, control technology, compressed air, water, etc.

The object is also achieved by a method for treating objects such as vehicle bodies and / or vehicle attachment parts. The method comprises the steps of: receiving a first workpiece carrier with a first object to be treated at a receiving location of a treatment module of an apparatus for treating objects; Moving the first workpiece carrier along a path within the treatment module to a first treatment unit of the treatment module; Treating the first item in the first treatment unit; Receiving a second workpiece carrier with a second object to be treated at a receiving location of a treatment module of an apparatus for treating objects; Moving the second workpiece carrier along a path within the treatment module to a second treatment unit of the treatment module; Treat the second item in the second treatment unit; Removing the first workpiece carrier of the first treatment unit; Method of the first workpiece carrier to a delivery point of the treatment module; Delivering the first workpiece carrier to another treatment module; Removing the second workpiece carrier of the second processing unit; Moving the second workpiece carrier to a delivery point of the treatment module; Dispensing the second workpiece carrier to another treatment module.

With the method according to the invention, it is possible to treat a plurality of objects on corresponding workpiece carriers in a corresponding number of treatment units within a treatment module with a separated conveyor technique. The Simultaneität the treatment allows a particularly advantageous control of the treatment process and allows, as already explained, a particularly simple expansion or reduction of the capacity of a treatment module and thus the entire system.

In an advantageous embodiment of the method can be provided that the dispensing of the workpiece carrier can be carried out serially from a first treatment module to a second treatment module. This may mean, for example, that after the removal of a treated object from a treatment center and the transfer to the second area, the now vacant treatment center is again occupied.

The transfer of the treated objects can alternatively be carried out in parallel. This may mean, for example, that first all treated objects are removed from the treatment units and transferred to the second treatment module and then the vacant treatment units are again occupied.

Furthermore, the transfer of a workpiece carrier over two treatment modules can take place simultaneously or sequentially. For example, the change of a workpiece carrier from a first treatment module into a second treatment module may take place simultaneously with a change of a workpiece carrier from the second treatment module into a third treatment module. Alternatively, however, it may also only the change of a workpiece carrier from the second treatment module into a third treatment module done, which then leaves a place in the second treatment module, which in turn can be occupied by a workpiece carrier from the first treatment module.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 shows a schematic representation of a first embodiment of a paint shop 10. The paint shop has a series of treatment modules 20, 30, 40, 50, 60, 70, 80, which are explained in more detail below. The paint shop 10 is merely an exemplary embodiment. However, the treatment plant could also be another form of treatment such as a pure drying plant, a pure assembly plant, a pure control / audit facility or a combination of the types of plant mentioned.

The paint shop 10 is designed for the coating of vehicle attachment parts 12 such as bumpers 121. Of course, in such a paint shop 10, other vehicle attachments such as wheels, etc. are coated. In the paint shop 10, the objects to be coated 12 on workpiece carriers 14 such as a conveyor carriage 141, also called Skid promoted. The drive of the workpiece carrier 14 takes place in principle via a known drive technology 16! like belt, roller or chain conveyors. To the alignment of the workpiece carrier 14 relative to the To be able to change the paint shop 10, turntables such as a turntable 161 are provided at corresponding locations in the paint shop 10.

The beginning of the paint shop 10 forms the feed point 18, at which a aligned by the turntable 161 workpiece carrier 14 can be introduced into the paint shop. The task of a workpiece carrier 14 on the turntable 161 can be done manually or automatically.

At the feed point 18, a first treatment module 20 connects. The treatment module 20 has a substantially cuboidal basic structure and comprises side walls 201-204, the structure of which is basically known and which depends on the type of treatment which is to take place in the treatment module and therefore will not be explained in detail here. Not shown is an upper boundary of the treatment module 20, which encloses a treatment space together with the bottom of the treatment module 20 shown only schematically.

Two opposite side walls 203, 204 of the first treatment module 20 are provided with receiving points and delivery points: a first side wall 203, which faces the turntable 161 and the feed point 18, has a first receiving position 205 and a first delivery point 206, a second side wall 204, which is opposite to the first side wall, has a second delivery location 207 and a second location 208. In the treatment module 20 there is a conveyor system 216 having a first conveyor section 2161 and a second conveyor section 2162. The first conveyor section 2161 connects the first receiving station 205 and the second discharge station 207, the second conveyor section 2162 connects the second receiving station 208 and the first discharge station 206.

The receiving and dispensing points 205-208 form openings in the side walls 203, 204, through which the workpiece carrier 14 can be moved through the conveyor 16 through. The openings may be visible and closable by, for example, high speed doors or other suitable barrier means.

The two conveyor sections 2161, 2162 of the conveyor system 216 pass through a two-part treatment zone 209 in the treatment module 20, which in FIG. 1 is shown in dashed lines. Within the treatment zone 209, an application robot 210 is arranged, which is designed, for example, for an application of a primer, also called a primer, and a clearcoat. The application robot 210 may, for example, carry two application heads for this purpose. Alternatively, two separate application robots may be provided. Depending on the preparation of the application robot 210, in a first section 211 of the treatment zone 209, which in FIG FIG. 1 is applied top, applied to a primer or applied in a second portion 212 of the treatment zone 209 a clear coat on an object to be treated.

After a task of a workpiece carrier 14 at the feed point 18 of the workpiece carrier 14 is generally promoted together with the workpiece 12 via the conveyor 16 in the treatment module 20. Concretely, the conveying section 2161 takes over a workpiece carrier 14 projecting partially into the interior of the treatment module 20 through the first receiving point 205 and conveys it into the first section 211 of the treatment zone 209. After application of the primer by the application robot 210, the workpiece carrier 14 can pass through the conveying section 2161 the second delivery point 207 are conveyed out of the first treatment module 20.

After application of the primer in the first treatment module 20, a first evaporation treatment module 30 connects, which comprises a designated with a dashed line Abdunstzone 307. The evaporation treatment module 30 has - as with the first treatment module 20 - side walls 301-304, as well as ceiling and floor (without reference numerals). The evaporation treatment module 30 has a conveyor system 316 with a turntable 3161 movable along a conveyor section 3162. The evaporation zone 307 has a plurality of treatment units: Four evaporation units 308 are arranged adjacent to one another and parallel to one another within the evaporation zone 307. In the in FIG. 1 shown operating state are two Abdunsteinheiten 308 already with a workpiece carrier 14, which carries an object to be treated 12 occupied.

For feeding the evaporation zone 307, the turntable 3161 takes over a workpiece carrier 14 from the first treatment module 20. For this purpose, the turntable 3161 moves along the conveying section 3162 of the conveyor system 316 to a first side wall 302, which is adjacent to the first treatment module 20. In this first side wall 302, a receiving location 305 is arranged so that it is complementary to the discharge point 207 of the first treatment module 20. The receiving location 307 makes it possible to transfer a workpiece carrier 14 from the first treatment module 20 into the evaporation treatment module 30.

The turntable 3161 takes over the workpiece carrier 14, moves away from the first side wall 302 with the workpiece carrier 14 by moving along the conveyor section 3162 in the direction of the second side wall 302, rotates the workpiece carrier 14 by 90 ° and conveys it into a free evaporation unit 308 Abdunstzone 307. Depending on the configuration of the evaporation zone 307 within the evaporation treatment module 30 and the process of the method after the acquisition of the workpiece carrier 14 can be omitted. If, for example, there are sufficient free spaces between the outer delimitation of the evaporation zone 307 and the side walls 302, 303, an evaporation unit 308 can already be loadable after the 90 ° rotation.

The number of the evaporation units 308 in the evaporation zone 307 correlates with the cycle time for taking over a workpiece carrier 14 from the first treatment module 20 and the desired evaporation time per evaporation process. After completion of a Abdunstvorgangs the turntable 3161 takes in turn the workpiece carrier 14 from the treatment unit 308, moves it optionally along the conveyor section 3162, rotates the workpiece carrier 14 by 90 ° and promotes him in the direction of the second side wall 307, in which a discharge point 306 is arranged.

The abatement treatment module 30 is followed by another treatment module, the basecoat treatment module 40.

The basecoat treatment module 40 has a ceiling and floor (not numbered), sidewalls 401-404, a basecoat treatment module 40 in two portions 410, 411 dividing partition 409, a conveyor 416 and each one in the sub-areas 410, 411 arranged painting robot 412, 413 on. In the subregions 410, 411, the conveyor system 416 has a first conveyor section 4161 and a second conveyor section 4162.

In a first side wall 402, which is adjacent to the evaporation treatment module 30, a first take-up point 405 is in the first portion 410, a second discharge point 406 in the second portion 411, and a second side wall 403 located in a first side wall 402 is in the first Subregion 410 a first delivery point 407 and in the second portion 411 a second receiving location 408 arranged.

The painting robots 412, 413 each define a treatment zone 414, 415, each represented by a dashed line.

The basecoat treatment module 40 is passed through twice by a workpiece carrier 14. First, the conveyor 416 takes over in the conveyor section 4161 via the receiving station 405 a workpiece carrier 14 which is conveyed by the evaporation treatment module 30 via the discharge point 306 and transports the workpiece carrier 14 in the first treatment zone 414, which is located in the first portion 410. There, the article 12 to be treated located on the workpiece carrier 14 is coated by the painting robot 412 with a first layer of basecoat material. After the coating process, the workpiece carrier 14 is transported further along the conveying section 4161 to the discharge point 407 in the second side wall 403.

The basecoat treatment module 40 is followed by a transfer module 50. The transfer module 50 has a first side wall 501 with a receiving point 502 and a discharge point 503 as well as further side walls, ceiling and floor, which do not have their own reference numerals.

Within the transfer module 50 is a conveyor 516, which has as essential components a first turntable 5161 and a second turntable 5162.

After taking over a workpiece carrier 14 from the delivery point 407 of the base paint treatment module 40 via the receiving point 502 through the first turntable 5161 rotates this performs the workpiece carrier 14 by 90 ° and passes the workpiece carrier 14 to the second turntable 5162. This in turn performs a rotation through 90 ° in the same direction and passes the workpiece carrier 14 via the discharge point 503 to the base paint treatment module 40, in particular to the second portion 411th

In the second subarea 411, similarly to the first subarea 410, again a basecoat coating by a painting robot 413 takes place. After application of the second layer of base coat by the painting robot 413, the workpiece carrier 14 is conveyed along the second conveying section 4162 through the conveyor 416 to the second delivery point 406.

There, the conveyor 416 transfers the workpiece carrier 14 to a second evaporation treatment module 60. The second evaporation treatment module 60 is constructed substantially identical to the first evaporation treatment module 30. It is therefore dispensed with a detailed description of the individual features. Identical or identical features begin with the numeral 6 instead of - as in the first treatment module 30 - with the numeral 3.

Upon request of the workpiece carrier 14 from the second portion 411 of the basecoat treatment module 40 via the delivery location 406, the turntable 6161 of the conveyor 616 of the second evaporation treatment module 60 at the receiving location 606 in the second side wall 603 takes over the workpiece carrier 14, rotating it by 90 ° and one of the free evaporation treatment units 608. If in one of the evaporation treatment units 608, the treatment process - ie the evaporation - completed, takes the turntable 6161 located therein workpiece carrier 14, optionally moves along the conveyor section 6162, rotates the workpiece carrier 14 and supports this along the conveyor section 6162 to the discharge point 605.

There, a transfer of the second evaporation treatment module 60 to the first treatment module 20. The conveyor 216 of the first treatment module 20 takes along the conveyor section 2162 at the second receiving location 208, the workpiece carrier 14 and promotes this in the second section 212 of the treatment zone 209th

There, the application robot 210 can apply a clearcoat to the object 12 to be treated on the workpiece carrier 14. After completion of the coating process, the workpiece carrier 14 is conveyed along the conveying path 2162 to the first discharge point 206. There may be a transfer of the workpiece carrier 14 to the next module in the manufacturing plant 10.

After the clearcoat, the workpiece carrier 14 is conveyed into the last flash treatment module 70. Again, the structure is comparable to the first treatment module 30. In contrast to the first treatment module 30, six evaporation units 708 are provided in the last evaporation treatment module 70.

After the transfer of the workpiece carrier 14, the turntable 7161 of the conveyor 716 of the treatment module 70 at the receiving location 706 of the first side wall 703 takes over the further transport of the workpiece carrier 14. A free evaporation unit 708 is occupied by the transferred workpiece carrier 14. Subsequently, a workpiece carrier 14, a Abdunsteinheit 708 whose Abdunstzeit has already expired, removed by means of the turntable 7161 of the Abdunsteinheit 708 and conveyed to the discharge point 705 of the second side wall 702.

Subsequent to the last evaporation treatment module 70, a combination of two dryer treatment modules 80, 90 and a distributor unit 100 is provided in the system 10. The dryer treatment modules 80, 90 are constructed essentially identical. It will therefore be discussed in detail on the first dryer-treatment module 80.

The first dryer treatment module 80 is constructed similar to the first evaporation treatment module 30. A series of drying units 808 are disposed adjacent to each other and parallel to each other within a treatment zone 807. A conveyor 816 with a travel table 8161, which is movable along a conveyor line 8162, is arranged within the drying treatment module 80.

Alternatively or additionally, the drying units 808 could also be arranged one above the other. In this case, the 8161 travel table would also be equipped with a lifting device.

As mentioned, a conveyor 8161 for linear conveyance along a conveyor line 8162 permits loading and unloading of the drying units 808. The transfer of a workpiece carrier 14 into the drying unit 808 can take place, for example, via a push / pull technique or via a non-driven transfer the drying unit 808 may be lowered / tilted for loading and raised / tilted for discharge.

The transfer of a workpiece carrier 14 to the displacement table 8161 via a receiving and delivery point 802 in a first side wall 801, which faces the distribution unit 100.

Similarly, the second dryer treatment module 90 also has a receiving and discharging location 902 in a side wall 901 that faces the distribution unit 100.

The distributor unit 100 has a conveyor system 116 with a turntable 1161 and a conveyor line 1162. The turntable 1161 is movable along the conveying path 1162 and adapted to receive a goods carrier 14 conveyed via the discharge point 705 of the last evaporation treatment module 70, to rotate through 90 ° and align it with one of the receiving and delivery points 802, 902 and into one of the to hand over two dryer treatment modules 80, 90. Accordingly, the distributor unit 100 is designed to take over after the completion of a drying process of an article on a goods carrier article 12 12 through the receiving and dispensing points 802, 902 and to promote a removal point 110. Optionally, if necessary, cooling of the treated article 12 on the workpiece carrier 14 can take place in the removal point. The transfer of the workpiece carrier 14 to the removal point 110 is possible via a delivery point 117.

In the FIG. 2 illustrated embodiment of a treatment plant 10 'has compared with in FIG. 1 illustrated treatment plant 10, the same treatment modules 20-70 regarding the coating and the evaporation processes. These treatment modules therefore have the same reference numerals 20-70 and will not be explained again.

By contrast, the drying treatment module 80 'is rotated by 90 ° compared to the drying area treatment modules 80 of the treatment installation 10 and directly adjoins the evaporation treatment module 70 without a distributor unit. It has in its treatment zone seven drying units 808 ', which are arranged adjacent to and parallel to each other. On a side wall 801 'facing the evaporation treatment module 70, the drying treatment module 80' has a receiving location 802 'and a delivery location 803'.

Within the drying treatment module 80 'is a conveyor 816' with a linearly movable displacement table 8161 ', which can be moved along a conveyor line 8162' back and forth and the drying units 808 'loading and unloading.
