A paint baking oven bakes a wet coating film applied to a vehicle body while conveying the vehicle body. The vehicle body has a main shell body to which side doors are attached via hinges. The topcoat paint baking oven includes a oven body and a hot air supplier that supplies hot air into the oven body. The oven body is configured to include a first oven body and a second oven body. The first oven body has a side-to-side width corresponding to a body width of the vehicle body in a state of closing the side doors. The second oven body has a width wider than the side-to-side width of the first oven body. The width of the second oven body corresponds to a body width of the vehicle body in a state of opening the side doors.

A paint baking method includes a process for conveying a vehicle body while exposing the vehicle body to a hot air atmosphere to bake a wet coating film applied to the vehicle body. In the vehicle body, hinges and door offset members are attached between hinge fastening parts of the main shell body and hinge fastening parts of the side doors. The distance between the hinge fastening parts of the main shell body and the hinge fastening parts of the side door in a state in which the hinges and the door offset members are attached is longer than a distance between the hinge fastening parts of the main shell body and the hinge fastening parts of the side door in a finished vehicle state.

A device for controlling the temperature of workpieces, in particular for drying vehicle bodies, having a housing, a temperature-controlling tunnel accommodated in the housing, and a temperature-controlling system for controlling the temperature of workpieces. The temperature-controlling system includes a full-space temperature-controlling device which can control the temperature of a workpiece as a whole, and a local temperature-controlling device which can control the temperature of locally delimited regions of the workpiece and which comprises multiple temperature-controlling units that can be activated and actuated independently of one another for this purpose. The full-space temperature-controlling device and the local temperature-controlling device are provided in the temperature-controlling tunnel such that a workpiece at least within an active section in the temperature-controlling tunnel can be under the influence of both the full-space temperature-controlling device as well as the local temperature-controlling device. A system and a method for controlling the temperature of workpieces are additionally provided.

A device for controlling the temperature of, and in particular for drying, objects, in particular vehicle bodies, having a housing which integrates a temperature-control chamber that includes at least one air outlet and at least one air inlet. The temperature-control chamber is assigned at least one heating unit in which it is possible to generate a hot primary gas flow and to which it is possible to supply, from the air outlet, air that is to be heated. The heating unit includes a heat exchanger device into which the hot primary gas can be guided and in which it is possible to heat air from the temperature-control chamber using hot primary gas, which air can be supplied, as heated recirculation air, in a circuit via the at least one air inlet back to the temperature-control chamber. The heating unit includes at least a first and a second flow outlet via which heated recirculation air leaves the heating unit.

The present invention relates to an annealing system which can be used to anneal workpieces, for example vehicle bodies. According to the invention, an annealing chamber, a feed air system, an exhaust air system and one or more air circulation systems are provided.

A drying furnace comprises a plurality of drying areas that are continuously provided along a longitudinal direction of the furnace and include a first hot air supply port, a second hot air supply port, and an exhaust port. The first hot air supply port is arranged at a position below a vehicle body in the furnace shell to discharge hot air diagonally upward. The second hot air supply port is arranged at a position higher than the first hot air supply port in the furnace shell to discharge hot air diagonally downward. The exhaust port is arranged at a position lower than the first hot air supply port and the second hot air supply port in the furnace shell to discharge the hot air outside the furnace shell. The drying furnace uniformly raises the temperature of the external and internal parts of the vehicle body while shortening the furnace length.

An apparatus for controlling the temperature of workpieces, in particular of vehicle bodies, has a temperature-control tunnel, a traction chamber and an intermediate floor which is arranged between the temperature-control tunnel and the traction chamber and which has a connection passage. The apparatus includes a conveying device for conveying the workpieces in the temperature-control tunnel, wherein the conveying device has at least one conveying carriage with a running gear and has a workpiece carrier for holding the workpieces of which the temperature is to be controlled. The running gear is arranged in the traction chamber and is connected by a connecting device, which projects through the connection passage of the intermediate floor, to the workpiece carrier arranged in the temperature-control tunnel. To control the temperature of the traction chamber and thus adequately protect the running gear against heat or cold, the intermediate floor is equipped at least in regions with an active cooling and/or heating means.

In order to provide a separating device for separating two spatial regions, which has a simple structure and provides for efficient fluid separation, it is proposed that the separating device comprises a supply device for supplying a separating fluid to be introduced between the two spatial regions, the supply device preferably comprising at least two guide elements for guiding the separating fluid, which guide elements are designed in particular as guide plates

A vehicle washing system includes a vehicle treatment area that is configured to receive a vehicle to be dried. At least one dryer media device is positioned in the vehicle treatment area. The at least one dryer media device is configured to dry the vehicle upon contact with the vehicle. An air moving assembly is located adjacent to the at least one dryer media device in the vehicle treatment area, and is configured to remove excess moisture from the at least one dryer media device.

A paint baking oven comprises an oven body and a hot air supplier that supplies hot air into the oven body. The paint baking oven bakes a wet coating applied to a vehicle body while conveying the vehicle body. The vehicle body includes a body exterior part and a narrow portion. The oven body is configured to include a spot baking region in which the hot air is blown primarily toward the narrow portion to locally bake a coating film applied to the narrow portion.
