2. Description of the Related Art Conventionally, as this type of technology, for example,
As shown in FIGS. 6 to 7, a hollow pillar 3 is externally fitted to a pillar portion 1 of a movable base 2 so as to be vertically movable, and a handle 4 is attached to the lowermost portion on the back side of the hollow pillar 3. Has been.
A vertically movable mounting member 6 having an arm 5 is externally fitted to the hollow column 3, and a plurality of heaters 7 for radiating heat rays are inelastic to the arm 5 of the vertically movable mounting member 6. A heater panel 8 arranged in a specific manner is attached. Further, a first pulley 27 is provided on the front side of the uppermost end of the hollow column 3, and a flexible member for moving the attachment member 6 having the heater panel 8 vertically through the pulley 27 without difficulty. One end of 28 is locked to the upper part on the front side of the mounting member 6, and the other end is locked to the uppermost part on the front side of the inner wall of the column 1 of the movable mount 2. And
A second pulley 29 is provided on the uppermost portion on the back side of the inner wall of the pillar portion 1 erected on the movable frame 2, and a flexible strip for reasonably moving the hollow pillar 3 up and down through the pulley 29. One end of 30 is locked to the lowermost portion on the back side of the hollow support column 3, and the other end is connected to a constant load spiral spring 31 that is axially attached to the lower portion of the inner wall of the column portion 1 of the movable mount 2.

In the heater panel 8 of the coating / drying apparatus 9 described above, the reflection plate 12 formed of a corrugated aluminum plate is fitted in the casing 32, and the reflection plate 1 is formed.
A plurality of heaters 7 are arranged between the two short walls 32a of the casing 32 at the front positions of the respective concave surfaces of the casing 2.

In the coating / drying apparatus 9 described above, the hollow support column 3 which is vertically fitted onto the column section 1 of the movable base 2 is lowered by its own weight while receiving the respective loads of the mounting member 6 and the heater panel 8. However, since the force of the action and the elastic force of the constant load spiral spring 31 that receives the tensile load due to the action of the action are equal, the hollow support column 3 has a predetermined position in the height direction. The stationary state is held by, while holding the handle 4 attached to the lower end on the back side of the hollow support column 3 by hand, the hollow support column 3 is applied with a slight force.
It is possible to move up and down freely. Also,
As the hollow support column 3 moves up and down, the heater panel 8 fixed to the arm 5 of the mounting member 6 also moves up and down.

Therefore, when using the above-mentioned coating drying apparatus 9, for example, when the coating film of the car body of an automobile is heated and hardened to be dried, the heater is moved to the height position of the portion which needs to be dried. The panel 8 is moved up and down to set the position. A plurality of heaters 7 arranged on the heater panel 8 radiate heat rays, and the reflectors 12 radiate the heat rays forward with the direction perpendicular to the heater panel 8 as the center.

[0007]

However, according to the above-mentioned prior art, although the height of the heater panel 8 can be easily adjusted, the heater panel 8 itself is inclined at a predetermined angle so that the heat rays are inclined downward or upward. There is a drawback that irradiation cannot be performed in various oblique directions. As a result, when a location parallel to the ground, such as the ceiling of a car body of an automobile or a hood, is irradiated with the heat radiation, the heat radiation radiated from the heater 7 of the heater panel 8 that is in the positional relationship perpendicular to the ground. Is radiated by being diffused forward around a direction parallel to the ceiling and bonnet, so that part of the irradiated heat rays is not absorbed by the ceiling or bonnet and its coating film, so efficient drying by heating and curing is possible. There is a problem that you cannot do it.

In some places, such as the lower part of the bumper of the vehicle body of an automobile, it is possible to heat-cure and dry more efficiently when the heat rays are radiated from the lower side to the upper side, so that the same problem as described above occurs.

Further, the heater panel 8 of the coating dryer 9
When the heater panel 8 is vibrated, the plurality of heaters 7 arranged on the heater panel 8 are only inelastically fitted to both ends of the short wall 32a of the casing 32 of the heater panel 8. However, since the vibration and the like are directly transmitted to the heater 7, there is a problem that the heater 7 is damaged when the vibration and the like are strong.

The present invention solves the above problems and enables the heat rays emitted from the heaters of the heater panel to move forward in various oblique directions so that the coating film of the material to be dried can be efficiently heat-cured and dried. It is an object of the present invention to provide a coating drying apparatus that can be diffused and irradiated.

It is another object of the present invention to provide a heater mounting member having elasticity that absorbs vibrations or the like even if the vibrations or the like are transmitted to the heater arranged in the heater panel of the coating dryer.
