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.

Paint baking oven and paint baking method

A paint baking oven is for a vehicle body that includes a body exterior part and a narrow portion. The paint baking oven bakes a wet coating film applied to a coated surface of the narrow portion. The paint baking oven includes a heat source, such as an infrared heater, a halogen heater, an induction heater, or a hot air generator, configured to give heat energy primarily to the coated surface of the narrow portion and a heat source mover configured to move the heat source toward and away from the narrow portion.

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.

Paint baking method and door offset device for vehicle body coating process

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 coat drying device dries a wet-coated film that is coated on a continuously transported coating object having first and second parts, where the second part has a greater heat capacity than the first part. The coat drying device includes a heat source and a heat source moving device. The heat source provides thermal energy primarily to a coating surface of a second part. The heat source moving device moves the heat source to the second part such that a spacing between the second part and the heat source is maintained within a predetermined range.

Coat drying device and coat drying method

A coat drying device dries a coated film that is coated on a continuously transported coating object having first and second parts, where the second part has a greater heat capacity than the first part. The coat drying device includes a drying furnace, a hot air supply device and a control unit. The coating object is conveyed inside of the drying furnace main body. The hot air supply device heats the coating object by blowing hot air to the drying furnace. The control unit controls the hot air supply device based on a heat capacity of the coating object. The control unit controls the hot air supply device such that, when heating the second part, hot air with a greater amount of heat is supplied to the second part than an amount of heat in the hot air that is supplied to heat the first part.

An electrode material drying method and apparatus for drying electrode material are provided for achieving quality improvement of batteries. Electrode material portions containing a solvent are spaced apart from each other on the metal foil. An inductive coil that inductively heats the metal foil faces the metal foil. An amount of heat applied to an uncoated portion of the metal foil between the electrode material portions is reduced below that of a coated portion of the metal foil on which the electrode material portions are arranged. The heat evaporates the solvent in the electrode material portions by causing the metal foil to generate heat with inductive heating while moving the metal foil and the inductive coil relative to each other in an arrangement direction, that is, a direction in which the electrode material portions are arranged.
