In particular, one or more people can enter the access area.

The one or more access openings can preferably be closed, in particular in order to avoid an undesired exchange of air with the surroundings of the treatment system.

To minimize an exchange of air and / or to minimize the entry of contaminants into the treatment room, it can be provided that the access opening comprises a lock and / or an air curtain and / or a compressed air shower, etc.

The access area is preferably accessible to a person from outside an enclosure of the treatment system through the access opening, in particular a door.

The access area is preferably accessible for one or more action devices starting from the treatment area through an access opening.

Furthermore, it is provided in particular that the access area is accessible to a person directly from outside the housing of the treatment system through the access opening. In particular, the person does not have to pass through the treatment area in order to get into the access area.

Preferably, the person does not come into contact with the atmosphere of the treatment area in order to get to the access area.

The access area preferably has a gas composition that differs from the treatment area, in particular a lower level of pollution, for example a lower solvent concentration.

In the access area, there is preferably a permanent atmosphere that allows a person to stay unprotected, while a higher concentration of pollutants, in particular a higher concentration of solvents, can be present in the treatment area, in particular with a pollution, for example solvent concentration, which is above a maximum workplace concentration.

In one embodiment of the invention, it can be provided that the treatment system comprises an air guiding device which comprises a circulating air device and / or a supply air guiding device.

A circulating air flow can preferably be passed several times through the treatment area by means of the circulating air guiding device.

A supply air flow, in particular a fresh air flow and / or a hall air flow, can preferably be supplied to the one or more access areas by means of the supply air guide device.

In particular, a supply air flow can be supplied to each of the spatial areas of the treatment room that are separated from the treatment area by means of one or more separating elements by means of the supply air guide device.

Supply air in general is, for example, fresh air and / or hall air. The supply air can be supplied unconditioned and / or unchanged from the respective source (for example from the surroundings and / or from the hall). As an alternative to this, a conditioned supply can take place, in which the supply air was or is conditioned in particular by heating, cooling, humidifying and / or dehumidifying.

By means of the air guiding device, a separate air supply to the one or more access areas on the one hand and the treatment area on the other hand is preferably possible, whereby in particular different pollutant loads, in particular solvent concentrations, are obtainable, in particular adjustable. In this way, the pollutant load in the one or more access areas can preferably be minimized in the sense of optimal personal protection, while, for example, in the sense of operating the treatment system in the most energy-saving way possible, the air passed through the treatment area is circulated several times and thus a cleaning effort when cleaning exhaust air as well as a Conditioning effort for conditioning the total air required is minimized.

It can be advantageous if the circulating air flow from the treatment area and the supply air flow from the one or more access areas can be combined to form an overall flow by means of the circulating air guiding device.

By means of the circulating air device, at least a partial volume flow of the total flow can preferably be fed back to the treatment area as a circulating air flow.

A partial volume flow of the total flow can preferably be discharged as exhaust air by means of an exhaust air duct.

In particular, the total flow is preferably divided downstream of a separation device for cleaning the total flow into the partial volume flow, which is again fed to the treatment area, and the exhaust air flow, which is cleaned, for example by means of a thermal cleaning device, in particular a regenerative thermal exhaust gas cleaning device, and finally released to the environment or otherwise used.

It can be advantageous if one or more, in particular all, access areas preferably each have an inlet which is arranged in particular at an upper end with respect to the direction of gravity of a spatial area of the treatment room separated from the treatment area by means of the one or more separating elements.

The inlet is arranged in particular in a ceiling area, in particular a ceiling wall, of the treatment room.

Furthermore, it can be provided that one or more, in particular all, access areas preferably each have an outlet which is arranged in particular at a lower end with respect to the direction of gravity of a spatial area of the treatment room separated from the treatment area by means of the one or more separating elements.

One or more outlets preferably open into the treatment area, in particular at a bottom area of the treatment area that is lower with respect to the direction of gravity.

As an alternative or in addition to this, it can be provided that one or more, in particular all, access areas do not have a separate outlet, but that the one or more access openings form the single outlet for the air flow fed to the access area.

Furthermore, it can be provided that one or more outlets open into a raw gas shaft arranged below the treatment room, so that it is provided in particular that the air discharged from the access areas is only merged with the air discharged from the treatment area downstream of the treatment area.

The flow cross-sections of the one or more access openings and of the one or more outlets are preferably selected so that the supply air, in particular fresh air and / or hall air, supplied via the one or more inlets, from the access area through the access opening in the direction of the treatment area flows.

As an alternative or in addition to this, it can be provided that one or more access openings and / or one or more outlets are dimensioned, in particular with regard to the respective flow cross-section, so that, in particular with a suitably selected volume flow, the supply air flow supplied via one or more inlets through the one or more access openings, an air flow is generated which is directed from the treatment area into the access area.

In a further development of the invention, it can be provided that the supply air passed through the access area, in particular fresh air and / or hall air, preferably with no or only slight contamination by the circulating air passed through the treatment area is used to flush one or more guide elements, in particular around one to avoid and / or at least minimize undesired escape of circulating air in the area of the one or more guide elements.

The admixture of supply air to the circulating air then occurs in particular in the area of the one or more guide elements.

It can be advantageous if the treatment system comprises a control device, by means of which the treatment system can optionally be switched into different operating modes.

1. a) Ein Behandlungsmodus, in welchem ein oder mehrere Werkstücke in dem Behandlungsbereich mittels einer oder mehrerer Aktionsvorrichtungen behandelt werden, wobei sich vorzugsweise keine Person in dem einen oder den mehreren Zugriffsbereichen aufhält oder aufhalten kann. Ein solcher Behandlungsmodus dient insbesondere zur Minimierung eines Zuluftbedarfs, wobei dann insbesondere in den Zugriffsbereichen keine für Personen ungeschützt zugängliche Atmosphäre herrscht.
2. b) Ein Sicherheitsmodus, in welchem ein oder mehrere Werkstücke in dem Behandlungsbereich mittels einer oder mehrerer Aktionsvorrichtungen behandelt werden, wobei sich vorzugsweise mindestens eine Person in dem einen oder den mehreren Zugriffsbereichen aufhält oder aufhalten kann. In einem solchen Sicherheitsmodus herrscht vorzugsweise in dem einen oder den mehreren Zugriffsbereichen eine Atmosphäre mit derart geringer Schadstoffbelastung, dass ein ungeschützter Aufenthalt für Personen ermöglicht ist. Insbesondere ist eine Schadstoffbelastung unterhalb der zulässigen maximalen Arbeitsplatzkonzentrationen in dem einen oder den mehreren Zugriffsbereichen vorgesehen, wenn die Behandlungsanlage in dem Sicherheitsmodus betrieben wird. Die Behandlungsanlage kann insbesondere in den Sicherheitsmodus versetzt werden, um Wartungs- und/oder Rüstaktionen an den Aktionsvorrichtungen durchführen zu können, während gleichzeitig im Behandlungsbereich weitere Behandlungsvorgänge an den Werkstücken durchgeführt werden. Es ist somit vorzugsweise kein vollständiger Stillstand der Behandlungsanlage erforderlich, um zumindest einzelne Wartung- und/oder Rüstaktionen an der einen oder den mehreren Aktionsvorrichtungen durchführen zu können.
3. c) Ein Wartungsmodus, in welchem keine Behandlung von Werkstücken im Behandlungsbereich erfolgt. Die Behandlungsanlage wird vorzugsweise nur dann in den Wartungsmodus versetzt, wenn Komponenten oder Bauteile der Behandlungsanlage gewartet werden müssen, welche auch in einem Zugriffszustand einer oder mehrerer Aktionsvorrichtungen nicht in einem Zugriffsbereich oder von dem Zugriffsbereich aus zugänglich sind.

In particular, one or more of the following operating modes are provided:

1. a) A treatment mode in which one or more workpieces in the treatment area are treated by means of one or more action devices, wherein preferably no person is or can be in the one or more access areas. Such a treatment mode is used in particular to minimize the need for supply air, in which case there is no atmosphere that is unprotected for people in the access areas.
2. b) A safety mode in which one or more workpieces in the treatment area are treated by means of one or more action devices, wherein preferably at least one person is or can be in the one or more access areas. In such a security mode, there is preferably an atmosphere in the one or more access areas with such a low level of pollutants that it is possible for people to stay unprotected. In particular, a pollutant load below the permissible maximum workplace concentrations is provided in the one or more access areas when the treatment system is operated in the safety mode. The treatment system can in particular be switched to the safety mode in order to be able to carry out maintenance and / or set-up actions on the action devices, while at the same time further treatment processes are carried out on the workpieces in the treatment area. It is therefore preferably not necessary for the treatment system to come to a complete standstill in order to be able to carry out at least individual maintenance and / or set-up actions on the one or more action devices.
3. c) A maintenance mode in which there is no treatment of workpieces in the treatment area. The treatment system is preferably only switched to maintenance mode when components or parts of the treatment system have to be serviced which, even when one or more action devices are in an access state, are not accessible in an access area or from the access area.

For example, using one or more sensors, which are arranged, for example, in or on one or more access openings, and / or on the basis of a maintenance prediction and / or a maintenance plan, the treatment system can, preferably by means of the control device, automatically as required in the treatment mode, the safety mode or put into maintenance mode.

Furthermore, one or more action devices can preferably be deactivated automatically by means of the control device with regard to one or more functions, in particular when the respective action device is put into the access state. For example, it can be provided that a high voltage applied to an action element of an action device is switched off when the action element in question approaches the access area and / or is moved into the access area.

It can be favorable if the treatment system has several safety areas and / or safety levels, which are graded in particular with regard to the degree of danger for a person and / or with regard to the likelihood of contamination and / or damage to a workpiece.

In particular, the safety areas and / or safety levels are arranged in such a way that the greater the distance from the treatment area, an increasingly lower risk level is provided.

In particular, different movement speeds of the workpieces and / or the action devices, in particular the action elements, can be provided in the individual security areas and / or security levels, wherein the highest movement speeds are preferably permissible in the treatment area itself, while the lowest speeds are preferably permissible in the access area or other areas accessible to people. In between, intermediate areas, in particular intermediate stages, can be provided in order to create transition areas between high and low movement speeds.

It can be favorable if the treatment system comprises one or more automatic maintenance devices, in particular cleaning devices, for one or more action elements in each case. In particular, an automatic cleaning device can be a so-called bell cleaner for cleaning one or more action elements, wherein the one or more action elements can in particular be application heads, in particular spray heads.

The one or more automatic maintenance devices, in particular cleaning devices, can be arranged, for example, outside the access area and / or on a side of the one or more partition elements, in particular partition walls, facing the treatment room.

In particular, it is provided that the workpiece treatment, in particular workpiece coating, is not interrupted in the safety mode.

The one or more action devices which are put into an access state, in particular in order to carry out a maintenance action and / or a set-up action, are preferably at least temporarily replaced with regard to their function by one or more further action devices of the treatment system.

The treatment system, in particular the action devices, can preferably be operated in a degradation mode in which all actions required for the treatment of the workpieces are assigned to those action devices that are not in an access state but in a standby state and / or treatment state.

It can be favorable if the treatment system has more action devices than are required to carry out the actions required to treat the workpieces. Thus, one after the other, individual or multiple action devices can be temporarily released from individual tasks and placed in the access state for carrying out one or more maintenance actions and / or set-up actions.

It can be provided that the treatment system comprises a conveying device by means of which the workpieces can be conveyed along a conveying direction into the treatment area, through the treatment area and / or out of the treatment area.

At least two access areas are preferably provided, which are arranged and / or formed on opposite sides of a vertical longitudinal center plane of the treatment system running parallel to the conveying direction.

The workpieces are thus in particular accessible from both sides, with simultaneous treatment on both sides and / or alternating one-sided treatment of the workpieces in each case being possible.

Alternatively or in addition to this, it can be provided that at least two access areas are provided, of which at least one access area is arranged in front of a treatment area with respect to the conveying direction and of which at least one further access area is arranged behind the treatment area with respect to the conveying direction.

A plenum for supplying air to the treatment area is preferably arranged above the treatment area, in particular directly above the treatment room.

The plenum can, for example, be a split plenum, that is to say a divided plenum, by means of which different air flows can be supplied to different areas of the treatment room. For example, circulating air can be supplied to the treatment area by means of a split plenum, while, for example, supply air, in particular fresh air and / or hall air, is supplied to one or more access areas.

The treatment system furthermore preferably comprises one or more fans for driving one or more air flows, in particular for driving the circulating air flow and / or the supply air flow and / or the exhaust air flow.

The treatment facility preferably comprises 100 a treatment area 108 in which the workpieces 102 can be introduced one after the other in order to carry out one or more treatment actions, in particular coating steps.

The treatment area 108 is in particular part of a treatment room 110 , which from an enclosure 112 the treatment plant 100 is surrounded.

The enclosure 112 is designed in particular essentially cuboid. The treatment room 110 is thus preferably also essentially cuboid.

The enclosure 112 comprises two opposing side walls 114 as well as an inlet side 116 . The inlet side 116 in particular comprises a feed opening 118 through which the workpieces enter the treatment room 110 can be introduced and / or removed from the same.

In the first case mentioned is the treatment facility 100 in particular a single box system with one-sided feed. In the latter case, the treatment system is a single box system with implementation or part of an action line.

With regard to a direction of gravity g is the treatment room 110 on its underside from a floor wall 122 and on its top from a ceiling wall 124 limited.

The treatment facility 100 preferably comprises a conveyor device 126 for conveying the workpieces 102 along a conveying direction 128 (see in particular 2 ).

The two opposite side walls 114 the enclosure 112 are in particular parallel to the conveying direction 128 aligned.

The inlet side 116 and the outlet side 120 are preferably essentially perpendicular to the conveying direction 128 aligned.

Like the one in particular 1 and 6th can be seen, includes the treatment facility 100 preferably multiple action devices 130 to carry out one or more actions to treat the workpieces 102 .

The actions are in particular coating actions and / or handling actions.

The action devices 130 are therefore in particular application devices and / or handling devices, for example application robots 132 and / or handling robots 134 .

Preferably both as an application robot 132 trained action devices 130 as well as other action devices 130 , which as handling robots 134 are formed, provided.

How in particular 2 can be seen are the action devices 130 preferably on both side walls 114 of the treatment room 110 intended.

In particular, there is an essentially mirror-symmetrical arrangement of the action devices 130 with respect to a vertical longitudinal center plane 136 of the treatment room 110 intended.

To simplify the description of the application devices 130 will be referred to in the following in particular 1 and 6th Referring to which only the action devices 130 on a single side wall 114 demonstrate. The opposite side wall 114 can be identical to those in the 1 and 6th illustrated action devices 130 be provided.

Furthermore, in alternative embodiments (not shown), individual action devices 130 be waived as well as additional further action devices 130 can be provided.

Of course, an asymmetrical arrangement of the action device can also be used 130 with respect to the vertical longitudinal median plane 136 be provided.

Like in particular from 6th includes the treatment facility 100 preferably one or more, for example three, guide elements 138 for guiding one or more action devices 130 . For example, are on each guide element 138 two action devices each 130 guided, in particular movably guided.

The guiding elements 138 especially form guide rails 140 or are designed as such.

The guiding elements 138 extend in particular along a guide direction 142 .

The direction of leadership 142 is in particular at least approximately parallel to the conveying direction 128 the conveyor 126 .

It can be favorable if two or more than two guide elements 138 each with two as application robots 132 trained application devices 130 are provided and / or serve to guide the same.

Another guide element 138 is preferably used to accommodate and / or guide one, two or more than two action devices 130 , which as handling robots 134 are trained.

The guide element 138 for receiving and / or guiding the one or more as a handling robot 134 trained action devices 130 is preferably under the one or more guide elements 138 arranged, which to accommodate one or more as an application robot 132 trained action devices 130 serve.

How in particular 7th As can be seen, each action device includes 130 preferably an action base 144 , by means of which the respective action device 130 in particular movable on the respective guide element 138 is arranged.

Each action device further comprises 130 preferably an action item 146 , which is used to carry out an action. An action item 146 can for example be a spray head for applying coating material.

Furthermore, an action item 146 for example a gripper, with which one is used as a handling robot 134 trained action device 130 for example to open doors, for example on a vehicle body 106 trained workpiece 102 attacks.

The base of action 144 and the action item 146 of each action device 130 are in particular at opposite ends of an action arm 148 of each action device 130 arranged.

The action arm 148 of each action device 130 is designed, for example, as an articulated arm and / or robot arm.

In particular, multiple joints and / or multi-axis robot arms can act as an action arm 148 be provided.

Like in particular from 2 it appears are the action devices 130 can be arranged in different positions and / or states of motion, with the action devices in particular 130 on different guide elements 138 can extend into overlapping areas of space. When moving the action device 130 along the guide elements 138 a potential collision can result.

By means of a (not shown) control device of the treatment system 100 can preferably coordinate the action device 130 take place in such a way that this, in particular by suitable positioning and / or alignment of the respective action arm 148 can be moved past each other without collision.

How in particular 3 can be seen, the bottom wall 122 be accessible by yourself. The bottom wall 122 can therefore have a walk-on floor 150 of the treatment room 110 form.

However, it is preferably provided that above the treatment room 110 limiting floor wall 122 an additional floor that can be walked on 150 is arranged, which for example in the area above the bottom wall 122 is retractable, pivotable and / or retractable.

The walkable floor 150 can then, in particular, only be introduced when required, for example to provide a walk-in area in the treatment room for maintenance purposes only 110 to accomplish.

The walkable floor 150 is preferably still below all Action devices 130 and / or below all guide elements 138 . This in particular enables easy accessibility of the action devices 130 and / or the guide elements 138 guaranteed in the event of maintenance. The walkable floor 150 is also preferably below the conveyor 126 arranged.

When the conveyor 126 is even accessible, arises preferably between the accessible floor 150 and a top of the conveyor 126 a step or an offset which is preferably at most approximately 70 cm, in particular at most approximately 60 cm, for example approximately 50 cm. Fall protection can be dispensable in such a case.

Like the one in particular 1 , 4th , 6th and 7th can be seen, includes the treatment room 110 preferably several from the treatment area 108 separated room areas, which are hereinafter referred to as access areas 152 are designated. In the following, the entire separated room areas are used as access areas 152 to allow a simple description of the invention. However, it can also be provided that the functionally as an access area 152 Room areas to be viewed are only sub-rooms of the treatment room 110 represent separated room areas.

An access area 152 in particular, is an area that a person can enter to gain access to one or more action devices 130 especially without the treatment area 108 having to enter or be exposed to its atmosphere.

The action devices 130 can be brought into an access state for this purpose in order to provide access for a person from the access area 152 from or in the access area 152 to enable. This will be discussed in more detail below.

The access areas 152 are in particular by means of several separating elements 154 spatially from the treatment area 108 Cut.

The dividers 154 are especially partition walls 156 .

For example, form the partitions 156 Shaft walls 158 one as a maintenance shaft 160 trained access area 152 .

The access areas 152 are preferably flushed and / or flowed through with supply air by means of a supply air guide device to be described below.

The supply air is in particular fresh air and / or hall air, preferably unconditioned fresh air and / or hall air.

The access areas 152 preferably have an inlet for this 162 on, which in particular at an upper end of the access area with respect to the direction of gravity g 152 is arranged.

Furthermore, there are preferably one or more outlets (to be described below) 164 intended. The outlets 164 can be provided in different variations. With regard to the 16 received below.

At this point it is only crucial that through the inlet 162 Supply air to the access area 152 is fed, which is due to the presence of the separating elements 154 , especially the partitions 156 not or only insignificantly with the gas, especially the circulating air, in the treatment area 108 mixed.

The through the access area 152 Flowing air thus has a low concentration of pollutants, so that people are unprotected in the access area 152 can stop, especially when in the treatment area 108 Work pieces 102 be treated.

At least one separator 154 preferably has an access opening 166 on.

By means of the access opening 166 is in particular a connection between the access area 152 and the treatment area 108 created.

In particular, it can be provided that at least one part, in particular an action element 146 , an action device 130 through the access opening 166 through into the access area 152 can be introduced in order to be able to carry out a maintenance and / or set-up action.

In particular, the action devices are 130 successively movable so that at least their respective action element 146 in the access area 152 protrudes or is arranged therein. By doing that on the action devices 130 in the access area 152 Maintenance and / or setup actions can be carried out and that the access area 152 preferably always or at least temporarily has an atmosphere that is harmless to people, the treatment of workpieces can 102 in the treatment area 108 preferably be continued while maintenance and / or set-up actions are being carried out.

Access to the access area 152 for one or more people is in particular through an access opening 168 in a side wall 114 the enclosure 112 the treatment plant 100 possible.

In particular, the access opening is 168 a door 170 through which a person enters the access area 152 can occur.

The access opening 166 is preferably such in at least one separating element 154 arranged that one through the access opening 166 in the access area 152 protruding action element 146 an action device 130 convenient for one in the access area 152 located person is accessible, for example at hip height and / or chest height.

In particular, a center of the access opening 166 is preferably at least about 1 m, for example at least about 1.20 m, and / or at most about 1.80 m, in particular at most about 1.60 m, above a floor that can be walked on 150 in the access area 152 arranged.

The access opening 166 preferably has a lower lower edge with respect to the direction of gravity g 172 and one of those lower edges 172 opposite upper edge with respect to the direction of gravity g 174 on. In addition, two are the two edges 172 , 174 interconnecting side edges 176 intended.

Preferably the top edge is 174 the access opening 166 at a height of no more than approximately 2 m above the accessible floor 150 , for example at a height of no more than approximately 1.80 m above the accessible floor 150 in the access area 152 .

A bottom edge 172 is preferably at least about 80 cm, preferably at least about 1.20 m, above the accessible floor 150 of the access area 152 .

The access opening 166 is preferably dimensioned so that one or more action items 146 one or more action devices 130 unhindered through the access opening 166 can be passed through, in particular can be stretched through. For example, the free passage area is the access opening 166 at least 50% larger, for example at least 100% larger, and / or at most approximately 500% larger, for example at most approximately 200% larger, than a maximum cross-sectional area of one or more, in particular all, action elements 146 , which through the respective access opening 166 in the access area 152 should be or can be brought in.

The shape of the access opening 166 can for example be chosen to be rectangular.

Alternatively, the access opening 166 also one on the outer contour of one or more, in particular all, action elements 146 have adapted shape.

The access opening 166 , in particular a geometric center thereof, is preferably essentially centered with respect to a height H of the treatment room 110 arranged, in particular in a range between approximately 30% to approximately 70%, preferably in a range between approximately 40% to approximately 60%, of the height H of the treatment room 110 .

It can be beneficial if the access opening 166 completely in a middle third of the treatment room 110 is arranged and / or formed based on its height.

It can be beneficial if the access opening 166 is arranged at least approximately at the same height as a workpiece 102 . It can also be provided that one or more access openings 166 with respect to a height direction running parallel to the direction of gravity above or overlapping with one or more workpieces 102 is arranged.

The action devices 130 are preferably optionally set to different states in order to carry out different actions.

In particular, a standby state or a treatment state can be provided in which workpieces 102 be treated or at least the readiness of the respective action device 130 this exists.

Furthermore, an access state is preferably provided in which the respective action device 130 in particular to carry out maintenance and / or set-up actions for the access area 152 is movable. In particular, an action element is in the access state 146 the respective action device 130 in the access area 152 arranged.

The action devices 130 are preferably designed in such a way that they can be moved past one another for switching to the access state and / or the treatment state and / or the standby state and in particular do not block one another, at least with exception of those action devices 130 , which on the same guide element 138 are led.

Further are the action devices 130 preferably designed and / or controlled in such a way that they have overlapping activity profiles and can thus at least partially replace one another, at least temporarily.

For example, two or more than two action devices 130 be designed and / or controlled to carry out the same coating process, so that this coating process in the event of a required maintenance of one of the action devices 130 continue to work on the workpieces 102 can be performed, namely by one of the action devices 130 while the further action device 130 placed in the access state and serviced, for example cleaned, in the access area.

One or more action devices 130 are thus in particular designed and / or arranged and / or controlled redundantly.

As the action devices 130 their operation poses a risk to people and / or other components of the treatment system 100 represent, for example due to high voltage flashovers, etc., are at the treatment plant 100 Preferably several safety areas are provided, which are graded in particular with regard to the respective hazard and / or damage potential.

How 9 can be seen, there is a particular one in the treatment area 108 located high risk area 177 .

To this high risk area 177 no person must have access when a treatment procedure is being performed. In the high risk area 177 are in particular the highest movement speeds of the action devices 130 permissible. In addition, it is in the high risk area 177 activated a high voltage supply to perform treatment procedures.

A low risk area 178 is especially the access area 152 . In this low risk area 178 become the action devices 130 preferably moved at the lowest speed. In addition, the high voltage is preferably deactivated, so that there is a risk of injury to people and a risk of damage to other components of the treatment system 100 is minimized as possible.

Between the high risk area 177 and the low risk area 178 are preferably further intermediate risk areas 180 provided, in which in particular graduated speed limits for the movement of the action devices 130 consist.

All areas 177 , 178 , 180 can be secured with additional security measures. For example, it can be provided that in individual areas, for example in the low-risk area 178 and / or in one or more adjacent intermediate risk areas 180 a movement of the action devices 130 is only permitted if a person approves this, for example by pressing an approval button.

Furthermore, it can be provided that one or more, in particular all, action devices 130 monitored, for example camera-monitored. One or more people can check the images and / or videos captured by one or more cameras, for example in a visualization, in particular to assess possible errors or the proper functioning of the treatment system 100 .

In 8th is a simplified representation of a ceiling wall 124 the treatment plant 100 shown.

About this ceiling wall 124 in particular one or more air flows to the treatment room 110 fed.

The ceiling wall 124 comprises in particular an essentially central filter cover 182 , via which a circulating air flow to the treatment area 108 is feedable.

The ceiling wall also includes 124 multiple inlets 162 for supplying an air flow, in particular one or more supply air flows 186 to the access areas 152 .

The access areas 152 are in corner areas 188 of the essentially cuboid treatment room 110 arranged.

The side walls 114 facing one or more additional flow areas can be created, with a corresponding air flow feed likewise via the ceiling wall 124 , optionally separated from the circulating air flow 184 , or via one or more guide elements 138 can be done.

In the 11 and 12th alternative flow variants are shown, which differ from the in 8th The flow guide shown essentially differ in that further flow areas, in particular between the Treatment area 108 supplied circulating air flow 184 and the access areas 152 supplied supply air flows 186 are created.

These further areas form in particular air locks or air curtains for more efficient separation of the atmosphere in the treatment area 108 on the one hand from the atmospheres in the access areas 152 on the other hand.

In the following, these areas are therefore referred to as separation areas 190 designated.

A separation area 190 can also alternatively or additionally in the area of a feed opening 118 and / or an opposite discharge opening 192 be provided, thereby in particular a lock function in the area of conveying the workpieces 102 can be achieved.

Incidentally, the in 11 Alternative flow guidance shown in terms of structure and function with the in 8th embodiment shown, so that reference is made to the preceding description thereof.

One in 12th Another alternative embodiment of a flow guide shown differs from that in 11 illustrated embodiment essentially in that not every access area 152 a separate supply air flow 186 is fed, but that rather between the two side walls 114 consistently two access areas each 152 sensing flow sections are formed.

These flow sections become the separation areas 190 from that of the treatment area 108 circulating air flow to be supplied 184 Cut.

Through suitable control of valves 194 the volume flows and / or speeds of the air flows to be supplied to the individual areas can preferably be controlled in a targeted manner, in particular to prevent pollution in the access areas 152 to minimize and at the same time the conditioning effort for conditioning the circulating air flow 184 and / or the supply air flow 186 to minimize.

Incidentally, the in 12th Alternative embodiment of the flow guide shown in terms of structure and function with the in 11 embodiment shown, so that reference is made to the preceding description thereof.

In 13th is a simplified representation of a treatment plant 100 pictured.

The treatment facility 100 is shown in a top view from above and includes in the corner areas 188 a treatment room 110 one access area each 152 , also two side walls opposite one another 114 arranged guide elements 138 , on each of which two action devices 130 are arranged to be movable.

By means of the action devices 130 is especially the treatment area 108 accessible to work pieces 102 (in 13th not shown to deal with.

Out 13th In particular, it appears that each action device 130 by moving them appropriately to access an access area 152 and thus maintenance and / or set-up actions on each action device 130 are feasible.

One in 14th illustrated alternative embodiment of a treatment plant 100 differs from the in 13th embodiment shown essentially in that only two access areas 152 are provided which between each two action devices 130 are arranged.

Any action device 130 thus shares an access area 152 with another action device 130 .

It can be provided that with respect to a conveying direction 128 in front of the access areas 152 arranged action devices 130 for the treatment of workpieces 102 in a first treatment area 108 serve, while those in the conveying direction 128 according to the access areas 152 arranged action devices 130 for the treatment of workpieces 102 in another treatment area 108 serve.

Thus are the access areas 152 at the in 14th illustrated embodiment of the treatment system 100 several action devices each 130 from different treatment areas 108 assigned.

In the 14th illustrated embodiment of the treatment system 100 can especially be used in treatment lines 196 Are used while the in 13th illustrated embodiment of the treatment system 100 especially a treatment box 198 can be.

The guiding elements 138 for guiding the action devices 130 are at the in 14th illustrated embodiment of the treatment system 100 by means of the access areas 152 interrupted.

However, it can also be provided that the access areas 152 essentially in the middle along the conveying direction 128 continuous guide elements 138 arranged and to the vertical longitudinal center plane of the treatment room 110 are arranged offset.

Incidentally, the in 14th illustrated embodiment of the treatment system 100 in terms of structure and function with the in 13th embodiment shown, so that reference is made to the preceding description thereof.

One in 15th illustrated embodiment of a treatment plant 100 differs from the in 14th embodiment shown essentially in that further action devices 130 and other access areas 152 are provided.

In particular, there are six access areas 152 provided, of which four are access areas 152 in the corner areas 188 are arranged.

Two more access areas 152 are in particular essentially centered with respect to the conveying direction 128 in the treatment room 110 arranged.

There are preferably eight action devices here 130 provided, with four guide elements 138 to guide the eight action devices 130 are provided.

The access areas 152 are in particular at the ends of the guide elements 138 arranged so that each action device 130 Access to one of the access areas 152 Has.

Incidentally, the in 15th illustrated embodiment of the treatment system 100 in terms of structure and function with the in 14th embodiment shown, so that reference is made to the preceding description thereof.

16 shows a schematic representation of an air duct, which in principle in all of the treatment systems shown and / or described 100 can be provided.

The following therefore focuses in particular on the treatment system 100 according to the 1 to 10 Reference, as all deviations, which result from 16 result, also with the treatment plant 100 according to the 1 to 10 can be provided.

The treatment facility 100 includes according to 16 in particular a circulating air device 200 , by means of which a circulating air flow 184 to the treatment area 108 is feedable.

The treatment facility also includes 100 an air supply device 202 , by means of which one or more supply air flows 186 , in particular fresh air flows and / or hall air flows, through the inlets 162 to the access areas 152 are supplied.

The supply of the circulating air flow 184 as well as the supply air flow 186 takes place in particular through a plenary session 204 , for example a split plenum above the treatment room 110 .

Under the treatment room 110 is in particular a separation device 206 the treatment plant 10 provided, by means of which the from the treatment room 110 discharged gas stream can be freed of impurities.

How 16 can be seen, for example, in the area of a raw gas shaft 208 below the treatment room 110 the circulating air flow 184 and the one or more supply air flows 186 brought together and thereby mixed.

Part of the total flow thus obtained is used as a circulating air flow 184 the treatment area again 108 fed. The return of the circulating air flow 184 , that is, the supply from below the treatment room 110 arranged area of the treatment system 100 in the one above the treatment room 110 arranged area of the plenary 204 preferably takes place within an outer contour of the treatment system 100 , for example according to 5 in particular, a width range can be used, which due to the side wall 114 protruding component of the guide elements 138 and / or action devices 130 on the outside of the side walls 114 is available.

How 16 It can also be seen that part of the total flow is preferably via an exhaust air duct 210 the treatment plant 100 discharged as exhaust air.

The part discharged as exhaust air essentially corresponds to the part supplied as supply air in order to maintain a constant pressure.

To merge the circulating air flow 184 with the one or more supply air flows 186 there are several options.

For example, it can be provided that the at least one supply air flow 186 exclusively through the access openings 166 through into the treatment area 108 flows in.

As an alternative or in addition to this, it can be provided that above or below the bottom wall 122 in a lower end area of the access area with respect to the direction of gravity g 152 one or more outlets 164 are provided through which the at least one supply air flow 186 to the circulating air flow 184 to be led.

The outlets 164 can in particular above the bottom wall 122 are arranged and thus open into the treatment area 108 .

It can also be provided that one or more outlets 164 directly into the raw gas shaft 208 open and thus only in the raw gas shaft 208 the mixing of the circulating air flow 184 with the at least one supply air flow 186 he follows.

By appropriately guiding the circulating flow 184 and / or the supply air flows 186 can in particular in the at least one access area 152 Atmospheric conditions can be achieved with minimal pollutant concentrations, which means that one or more people remain unprotected in the at least one access area 152 allow. The treatment of workpieces 102 in the treatment area 108 is thus the implementation of maintenance and / or set-up actions on the one or more action devices 130 not in the way. The treatment facility 100 can thus be used particularly efficiently for workpiece treatment.
