Description

Separating device, treatment system, method for separating two areas of space and method for treating workpieces

The present invention relates to a separating device for separating two room areas, for example two treatment room sections of a treatment room of a treatment system.

For example, locks can be provided at an inlet or an outlet of a treatment room of a treatment plant for treating workpieces in order to enable an efficient separation of a fluid arranged within the treatment room, in particular air, from the ambient air surrounding the treatment plant. In particular, an undesired exchange of air can be minimized or prevented, whereby, for example, energy expenditure for conditioning the fluid arranged in the treatment room, in particular for conditioning air, can be minimized.

Such locks can enable efficient fluid separation, for example by generating flow rollers, but usually require a relatively large installation space.

For example, a distance between the two guide elements can be at most approximately 5 cm, for example at most approximately 2 cm.

It can be advantageous if at least two guide elements are connected to one another, for example by means of webs which in particular extend parallel to a main flow direction of the separating fluid in the area between the at least two guide elements.

In one embodiment of the invention it can be provided that one or more or all guide elements extend at least in sections over at least about 5%, for example at least about 10%, preferably at least about 20%, of a maximum or average height of a passage connecting the two spatial areas opening extend.

It can be provided that the separating device comprises a blocking device for blocking the separating fluid.

The blocking device preferably comprises one or more blocking elements which prevent or at least reduce a flow of separating fluid from spreading into at least one of the two spatial areas.

One or more blocking elements are preferably arranged in a floor area of the separating device, for example arranged and / or fixed on a floor of one or both spatial areas.

One or more or all of the blocking elements are preferably designed as impact elements, in particular impact plates.

It can be favorable if one or more or all of the blocking elements extend upwards starting from the floor area, in particular starting from the floor, in particular extending upwards at least approximately vertically.

It can be favorable if one or more or all of the blocking elements of the blocking device are arranged offset parallel to a separation plane along which the two spatial areas can be separated from one another by means of the separation device.

The parting plane extends in particular between the two guide elements.

The parting plane is preferably a plane of symmetry, in particular a mirror plane, of the two guide elements. It can be favorable if the parting plane is arranged essentially vertically; the parting plane preferably forms a center plane of a feed slot of the feed device for feeding the separating fluid between the two spatial areas.

It can be favorable if the separating device comprises a discharge device for discharging the separating fluid.

The discharge device is arranged in particular in a floor area of the separating device, for example integrated into a floor of one or both space areas.

The discharge device preferably comprises one or more suction slots, which in particular are partially or at least approximately completely arranged parallel to the parting plane of the separating device.

It can be favorable if one or more or all of the suction slits run along one or more planes which are arranged offset parallel to the parting plane.

One or more or all of the suction slits are preferably arranged and / or formed continuously along the respective plane or else arranged and / or formed in several parts and interrupted.

It can be advantageous if the discharge device, in particular an outlet opening, for example a suction slot, on the one hand and one or more blocking elements of a blocking device of the separating device on the other hand are arranged on opposite sides of a separating plane of the separating device. The one or more or all of the blocking elements of the Blockiervor direction are preferably offset with respect to the parting plane, in particular starting from the parting plane, to one of the spatial areas, while one or more or all of the outlet openings, in particular suction slots, preferably with respect to the parting plane, in particular starting from the parting plane, to which further of the two spatial areas are arranged offset.

Such an arrangement makes it possible, in particular, that a separating fluid curtain extends downwards essentially along the separating plane of the one or more guide elements and can be suctioned off on one side in a bottom region of the separating device, with a flow spreading to the other side at the same time by means of the one or the plurality of blocking elements is prevented or at least reduced.

This enables, in particular, a particularly space-saving and flow-efficient separation of the two spatial areas from one another.

The separating device is particularly suitable for use in a treatment system for treating workpieces.

The present invention therefore also relates to a treatment system for treating workpieces, in particular a drying system for drying coated vehicle bodies.

The treatment system preferably comprises the following: a treatment room for treating workpieces, which includes one or more treatment room sections; at least one separating device for separating two room areas, in particular a separating device according to the invention, at least one treatment room section forming one of the room areas which can be separated from another of the room areas by means of the at least one separating device.

It can be provided that the further room area is a further treatment room section of the treatment room.

As an alternative to this, it can be provided that the further space area is a space section of a device different from the treatment system.

Furthermore, as an alternative to this, it can be provided that the further spatial area is an area surrounding the treatment system.

It can be favorable if the treatment system comprises a conveying device for conveying the workpieces, which in particular extends along a conveying direction of the conveying device through the separating device.

The parting plane of the separating device is then aligned in particular at an angle, for example perpendicular, to the conveying device.

It can be favorable if the conveying device is a clocked conveying device.

The parting plane preferably runs between two immediately neighboring positions or places at which workpieces to be treated linger at least temporarily, for example due to a cyclic conveyance. Within one cycle of a conveyor device designed as a cycle conveyor device, a workpiece is preferably conveyed from a cycle location (position, location) arranged in one of the spatial areas to a subsequent cycle location (position, location) arranged in the further spatial area.

In one embodiment of the invention, it can be provided that an underside of one or more or all of the guide elements is at least partially or at least approximately complementary to a conveying contour of the workpieces to be conveyed by means of the conveying device.

In particular, an underside of one or more or all of the guide elements is at least partially and / or at least approximately complementary to an upper side of a spatial area swept over by the workpieces when conveying them along the conveying direction.

The feed device of the separating device, in particular one or more or all of the guide elements, are preferably designed to be adapted to a workpiece contour.

For example, if the treatment system is used to treat vehicle bodies, it can be provided that an underside of one or more or all of the guide elements has an area arranged further up in the vertical direction, which is shaped like a roof area of the vehicle bodies, while an underside continues in the vertical direction The area of the underside of one or more or all of the guide elements arranged below is shaped like a front hood area. Furthermore, an intermediate area of the underside of one or more or all of the guide elements, which is oriented obliquely to the vertical direction and connects the area further up and the area further down, is provided, which is shaped like a windshield area of the vehicle bodywork. In one embodiment of the invention it is provided that the treatment system comprises several treatment room modules.

Each treatment room module preferably surrounds a treatment room section and / or forms a cycle location of a cycle conveyor device.

The separating device is arranged, for example, between two treatment room modules or integrated between two treatment room modules.

One or both of the treatment room modules adjoining a separating device preferably have no suction for a circulating air device. In this way, a flow guidance can be optimized in favor of a separating fluid flow.

In particular, a separating fluid curtain, for example an air curtain, can be generated in a substantially vertical direction, in particular while minimizing a cross-flow of a circulating air flow that reduces the separating effect.

The present invention also relates to a method for separating two spatial areas by means of a separating device.

The object on which the invention is based in this regard is to provide a method which can be carried out easily and which enables efficient fluid separation.

According to the invention, this object is achieved by the features of the independent method claim.

The method for separating two spatial areas by means of a separating device is in particular a method for separating two spatial areas by means of a separating device according to the invention. In the method for separating two spatial areas, a separating fluid is preferably introduced between the two spatial areas by means of a feed device.

The separating fluid is preferably guided by means of at least two guide elements.

The at least two guide elements are preferably designed as guide plates.

It can be favorable if the at least two guide elements are arranged at least approximately parallel to one another and / or at least approximately vertically to one another.

The method according to the invention for separating two spatial areas is particularly suitable for use in a method for treating workpieces.

The present invention therefore also relates to a method for treating workpieces, in particular for drying coated vehicle bodies.

Preferably, the method for treating workpieces comprises the following:

Passing workpieces through a separating device for separating two spatial areas;

Separating the spatial areas from one another by supplying a separating fluid flow between the two spatial areas, in particular by performing the method according to the invention for separating two spatial areas. One or more of the methods described preferably have one or more of the features and / or advantages described in connection with the separating device according to the invention and / or the treatment system according to the invention.

Furthermore, the separating device, the treatment system and / or one or more of the methods described preferably have one or more of the features and / or advantages described below:

The separating device can, for example, form an inlet lock / inlet lock or outlet lock / outlet lock of any system, for example a treatment system.

Furthermore, the separating device can form an intermediate lock within a treatment system or between two treatment systems.

The formation of a flow roller is preferably prevented or at least minimized by means of the separating device. The separating effect of the separating device results preferably at least for the most part from a separating fluid curtain produced by means of the feed device.

The separating fluid is fed to one or more or all of the guide elements, in particular in an area between two guide elements, preferably via a, for example, funnel-shaped mouth section, which is arranged in particular in a ceiling area, for example on a ceiling wall.

Via the mouth section, for example, a guide channel formed between the two guide elements is preferably in fluid connection with a pressure chamber, which is formed, for example, in a pressure chamber box above one or both spatial areas. Such a pressure chamber box can for example be provided with one or more filter elements and / or one or more fans in order to clean and / or drive the separating fluid before it is supplied between the two space areas.

The mouth section preferably extends at least approximately over an entire width of the at least two guide elements and / or the passage opening.

A temperature of the separating fluid is preferably higher than the temperature of the fluids in one or both spatial regions.

The separating device separates, for example, two spatial areas from one another in which different temperatures, in particular mean gas temperatures and / or mean room temperatures, prevail.

In one embodiment, it can be provided that the separating device follows a colder spatial region along or against the conveying direction. Furthermore, it can be provided that a warmer spatial area follows the separating device along or against the conveying direction.

The information "colder room area" and "warmer room area" relate to one another, which means that the temperature in the colder room area is lower than in the warmer room area.

In particular, in order to at least partially compensate for an admixture of colder gas from the colder area of the room into the separating fluid and / or into the warmer area of the room, it can be provided that the separating fluid has a temperature in comparison to the temperature in the warmer area of the room and / or in comparison to the temperature in the is supplied to a colder area of the room at an increased temperature. As an alternative to this, it can be provided that the separating fluid is supplied at a temperature that is reduced in comparison to the temperature in the warmer area of the room and / or in comparison to the temperature in the colder area of the room. In this way, in particular, overheating of the colder area of the room can be avoided if warmer gas flows from the warmer area of the room into the colder area of the room.

It can be favorable if at least one blocking element is arranged in the colder area of the room.

It can also be favorable if at least one outlet opening, in particular at least one suction slot, is arranged in the warmer area of the room.

It can be advantageous if the temperature of the separating fluid is between a temperature, in particular average room temperature and / or average gas temperature, in the warmer room area and a temperature, in particular average room temperature and / or average gas temperature, in the colder room area, in particular before the inflow and / or during the inflow of the separating fluid between the two spatial areas.

It can be particularly favorable if the separating device separates two spatial areas from one another in which there are different temperatures, the separating fluid being able to be supplied by means of the supply device at a temperature which is between the temperature in a warmer of the two spatial areas and the temperature in a colder one both room areas.

In particular, to vary the temperature of the separating fluid, it can be provided that a supply air flow, for example a gas flow that is unconditioned at least in terms of temperature, for example fresh air flow, can be fed to the separating fluid, in particular upstream and / or can be admixed in the feed device. The supply air flow is, for example, a Bypass flow, which bypasses or can be guided past a fresh air heat exchanger.

It can be favorable if the separating fluid is provided as a hot separating fluid and then divided between at least two different separating devices, the separating fluid being cooled in one of the separating devices, in particular in exactly one of the separating devices, by admixing a fluid, preferably the supply air flow, optionally within the feed device and / or between the at least two guide elements.

The separating device in which the separating fluid cooled by means of the supply air flow is fed is, for example, an inlet lock / inlet lock, an intermediate lock or an outlet lock / outlet lock.

In one embodiment of the invention, it can be provided that a gas flow, for example circulating air flow, which is directed into the one or more spatial areas by means of one or more inlet openings arranged directly adjacent to a separating device, with regard to its mass flow and / or its volume flow, with regard to a flow rate of the gas flow and / or its temperature deviates from the gas flow directed through other inlet openings, optionally all other inlet openings. For this purpose, a control can be provided, for example, which is designed and set up to carry out individual or more method features and / or by means of which the deviations can be controlled and / or regulated, for example using valve devices, flap devices and / or regulating devices. One or more mechanically and / or manually or automatically actuatable throttle plates can simply be provided for this purpose.

It can be favorable if one or more inlet openings arranged directly adjacent to a separating device have at least one valve device and / or flap device and / or regulating device or if at least one valve device and / or flap device and / or control device is assigned to one or more inlet openings arranged directly adjacent to a separating device.

Furthermore, it can be favorable if all the inlet openings of a room area, in particular a treatment room section, arranged directly adjacent to a separating device include at least one valve device and / or flap device and / or control device or if at least one valve device and / or flap device and / or control device includes all inlet openings one is assigned in a space area, in particular a treatment space section, arranged directly adjacent to a separating device.

Preferably, by means of at least one valve device and / or flap device and / or control device, a gas flow supplied through one or more inlet openings in the immediate vicinity of the separating device is reduced in terms of its flow velocity and / or in terms of its momentum in order to influence a separating fluid flow in the separating device as little as possible.

One or more flap devices and / or valve devices and / or regulating devices can in particular directly influence an opening cross-section of an inlet opening and / or an inflow cross-section on a filter device.

For example, a reduced mass flow and / or volume flow can be provided for inlet openings arranged closer to the separating device.

The feed device is preferably designed to be self-regulating, in particular in order to achieve an air flow that is as uniform as possible in the parting plane of the parting device. In particular, results from a Workpiece contour adaptation of the guide elements is a flow path that varies across the width of the guide elements, in particular with regard to a guide-free flow path, sections with a shorter guided flow path between the guide elements result in an overall lower flow resistance, so that despite different lengths of guide-free paths of the separating fluid along the parting plane a preferably at least approximately uniform flow of separating fluid can be obtained. In particular, a uniform curtain of separating fluid can be generated in this way.

Identical or functionally equivalent elements are provided with the same reference symbols in all figures.

A treatment system shown in FIGS. 1 to 8 and designated as a whole by 100 is used, for example, to treat workpieces 102.

The workpieces 102 are, in particular, vehicle bodies which are dried by means of the treatment system 100.

In particular, the treatment system 100 is a painting system and / or drying system.

The treatment system 100 includes, in particular, a housing 104 which surrounds a treatment space 106.

The treatment room 106 comprises in particular a plurality of treatment room sections 108.

The treatment system 100 preferably comprises a plurality of treatment room modules 110, each treatment room module 110 preferably surrounding a treatment room section 108 of the treatment room 106.

The treatment system 100 furthermore preferably comprises a conveying device 112, by means of which the workpieces 102 are conveyed along a conveying direction 114 can be passed through the treatment room 106 (see in particular FIGS. 5 and 6).

One or more treatment room modules 110 preferably include a circulating air duct 116, in particular a circulating air duct 116 in each case.

Each circulating air duct 116 preferably comprises one or more inlet openings 118 for supplying a circulating air flow to the respective treatment room section 108.

Optionally, each circulating air duct 116 can also have one or more outlet openings in order to be able to discharge circulated air from the respective treatment room section 108, in particular to be able to suck it off.

By means of the at least one circulating air duct 116, in particular a circulating air flow oriented essentially transversely, for example at least approximately perpendicularly, to the conveying direction 114 can be generated within the respective treatment room section 108.

In the embodiment of a treatment system 100 shown in FIGS. 1 to 8, a separating device 120 is preferably provided, by means of which the two treatment room sections 108 of the two treatment room modules 110 can be separated from one another, preferably in a fluidically effective manner.

In particular, a fluid exchange, in particular air exchange, between the two treatment room sections 108 can preferably be prevented or at least reduced by means of the separating device 120.

For this purpose, the separating device 120 is preferably arranged between the two treatment room modules 110 or arranged in an end region of the further treatment room module 110 facing a treatment room module 110 or integrated therein. The separating device 120 comprises, in particular, a feed device 122 for feeding a flow of separating fluid, for example an air flow.

For this purpose, the feed device 122 comprises in particular a fan 124 for driving the separating fluid flow and optionally one or more conditioning units for heating, cooling, dehumidifying and / or humidifying the separating fluid flow and / or one or more filter elements 126 for removing contaminants from the separating fluid flow.

The separating fluid flow is in particular an air flow, for example from an environment 128 of the separating device 120 and / or the treatment system 100.

The separating fluid flow is preferably sucked in by means of a suction 130 and fed to one or more guide elements 134 of the feed device 122 via a pressure chamber box 132 of the feed device 122.

As can be seen in particular from FIGS. 6 and 7, the pressure chamber boxes 132 are fluidically connected by means of an opening section 136 to a guide channel 138 formed between two guide elements 134, so that separating fluid from the pressure chamber boxes 132 can be introduced between the two guide elements 134.

The mouth section 136 is preferably arranged and / or embodied in a substantially V-shape in a cross section and / or longitudinal section.

By means of the mouth section 136, in particular, a uniform supply of the separating fluid to the guide channel 138 is possible.

The guide elements 134 are preferably formed out as guide plates 140. The guide elements 134 are preferably arranged essentially parallel to one another and / or extend, starting from a ceiling area 142, at least approximately parallel to a direction of gravity 144 downwards.

In particular, it can be provided that the guide elements 134 are arranged on a ceiling wall 146 of one or both treatment room modules 110 of the treatment system 100, in particular fixed thereto.

The guide elements 134 are in particular arranged and / or designed to be rigid and / or immovable.

As can be seen in particular from FIGS. 1 and 4, a feed opening 148 of the feed device 122 is gebil det by means of the guide elements 134.

The feed opening 148 is in particular a feed slot 150 which is arranged and / or formed in particular on an underside 152 of the guide elements 134.

The underside 152 is in particular an end of the guide elements 134 facing away from the ceiling area 142.

In particular, an underside 152 of the guide elements 134 is a lower end of the guide elements 134 with respect to the direction of gravity 144.

As can be seen in particular from FIG. 4, the feed opening 148 preferably extends at least approximately over an entire width B of a passage opening 154, which connects the spatial areas 156 to be separated from one another by means of the separating device 120, in particular the treatment room sections 108. The guide elements 134 preferably have a shape which is at least approximately complementary to an outer contour of a workpiece 102 to be treated.

In particular, the underside 152 of the guide elements 134 is designed to be at least approximately complementary to an upper side of an outer contour of a workpiece 102 to be conveyed through the separating device 120.

The guide elements 134 can thus in particular form a screen which reduces the passage opening 154 at least approximately to that shape and / or that cross section which is required for conveying the workpieces 102 through the separating device 120.

By means of the feed device 120, in particular a flow of separating fluid can be introduced along the direction of gravity 144 from top to bottom between the two space areas 156, in particular the two treatment space sections 108.

As can be seen in particular from FIGS. 6 and 8, in a bottom area 158 of the separating device 120 opposite the top area 142, preferably no discharge opening directly against which the feed device 122 flows is arranged and / or formed.

Rather, a combination of one or more outlet openings 160 and one or more blocking elements 162 of a blocking device 164 is preferably provided.

A discharge device 166, which in particular comprises the one or more outlet openings 160, is preferably not arranged in a direct extension of the guide elements 134, but rather offset along the conveying direction 114. In particular, the two outlet openings 160 are designed as continuous and / or interrupted suction slots 168, which in particular extend in the base area 158 at least approximately parallel to a dividing plane 170 of the dividing device 120.

The parting plane 170 is in particular a mirror plane of the guide elements 134 and / or a center plane of the guide channel 138.

In particular, the parting plane 170 is formed at least approximately perpendicular to the conveying direction 114.

The parting plane 170 can furthermore be a plane arranged and / or running between the two treatment room modules 110.

Preferably, all of the outlet openings 160 of the discharge device 166 are arranged on a single side of the parting plane 170.

On a further side of the parting plane 170 opposite this side, one or more blocking elements 162 of the blocking device 164 are preferably arranged.

As can be seen in particular from FIG. 6, the blocking elements 162 extend from the bottom region 158, in particular a bottom wall 172, upwards, in particular against the direction of gravity 144 upwards.

The one or more blocking elements 162 in particular enable a damming effect such that separating fluid, which is guided from top to bottom along the direction of gravity 144 and which is deflected in the bottom region 158, is blocked at least in one direction parallel to the conveying direction 114 by means of the guide elements 134. In the embodiment of the treatment system 100 shown in FIGS. 1 to 8, one or the other a plurality of blocking elements 162 in particular causes the separating fluid to spread in the bottom region 158 counter to the conveying direction 114 and thereby, for example, not to form a flow roller.

By means of the one or more outlet openings 160, which are arranged on a side of the parting plane 170 opposite the one or more blocking elements 162, the parting fluid can preferably also be sucked off without the formation of a flow roller.

A separating fluid curtain generated by means of the separating fluid, in particular an air curtain, thereby preferably has a particularly small extent along the conveying direction 114, so that the separating device 120 as a whole can take up a small amount of space.

As can be seen in particular from FIGS. 1, 2 and 5, a plurality of blocking elements 162 or at least one or more interrupted blocking elements 162 are preferably provided, with one or more elements of the conveyor device 112, for example rails or the like, between one or more interruptions 174 , are passed through.

Furthermore, in particular with regard to FIGS. 6, 7 and 8, the option of a compensation device 176 should be pointed out.
