Description

  The present invention relates to a paint drying apparatus.

  A conventional paint drying device used to dry paint, for example, paint applied to the body of a car, has a heater, a base for fixing the drying device to the ground, and a vertical installation on the base. And a fixing portion for fixing the heater to the column. The fixing portion is slidably attached to the column along the column, and the position of the heater can be changed to a desired position in the vertical direction by moving the fixing unit along the column.

  However, in the conventional paint drying apparatus, the vertical position change of the heater is manually performed. Specifically, the fixing part is released, the heater is held by human power, the heater and the fixing part are moved manually along the support column, the heater is moved to a desired position, and the fixing part is operated again. The position of the heater is changed by fixing the heater to the column. Thus, when changing the position of the heater, in addition to the weight of the heater, the heater must be moved against the frictional force between the fixed portion and the support column caused by the sliding of the fixed portion. Further, a conventional paint drying apparatus generally has a plurality of heaters, and the plurality of heaters are fixed to the support column by one fixing portion. The length of each heater in the longitudinal direction is generally 0.6 to 1.8 m, and its weight is 2 kg to 40 kg or more. Accordingly, the weight of the heater of one paint drying apparatus is several tens of kg or more. For this reason, the weight of the heater is heavy, and a large frictional force is generated by sliding of the fixed portion when the position of the heater is changed. As described above, in the conventional paint drying apparatus, the load on the operator when changing the position of the heater is very large, and a great amount of labor is required for changing the position of the heater. It was difficult.

  An object of the present invention is to provide a paint drying apparatus that can reduce a load applied to an operator when changing the position of a heater and can easily change the position of the heater.

In order to achieve the above object, a paint drying apparatus according to the present invention is a paint drying apparatus including at least one heater and a support device that supports the heater, and the support device includes a base, A vertical column that is erected on the base; and a holding unit that holds the heater at a predetermined height. The holding unit is a horizontal column that is attached to the heater, and the horizontal column. Is movable along the vertical column and fixed to the vertical column, and a lifting unit that lifts the heater. The lifting unit lifts the heater in the vicinity of the heater. The lifting means includes a wire part and an elastic part, and one of the wire part and the elastic part is attached in the vicinity of the heater, and the other of the wire part and the elastic part is The lifting means is stretched between the vicinity of the heater and the lower part of the holding part via the upper part of the holding part, and the heater is connected via a connecting member. It is attached to the transverse member, and one of the wire part and the elastic part is attached to the heater side tip of the transverse column .

Preferably, in the paint drying apparatus according to the present invention, the heater is rotatably attached to the connection member.

  More preferably, in the paint drying apparatus according to the present invention, the horizontal column can be expanded and contracted in the longitudinal direction of the horizontal column.

  More preferably, in the coating material drying apparatus according to the present invention, the vertical column is vertically installed on the base, and the movable fixing unit orthogonally crosses the horizontal column with the vertical column. To hold.

  According to the paint drying apparatus of the present invention, the lifting means for lifting the heater lifts the heater in the vicinity of the heater. Thus, since the lifting means lifts the heater, it is possible to reduce the frictional force generated by sliding along the vertical column of the moving fixed portion when changing the position of the heater, and the operation necessary for changing the position of the heater. The person's power can be reduced. For this reason, it is possible to reduce the load on the operator when changing the position of the heater, and to easily change the position of the heater. Further, since the lifting force of the heater acts in the vicinity of the heater away from the moving fixed portion, the moment generated in the moving fixed portion by this lifting force can be increased. For this reason, since the frictional force generated when the heater position is changed can be further reduced, the load on the operator can be further reduced, and the heater position can be changed more easily. In addition, the force required to change the position of the heater can be further reduced with a smaller lifting force.

  According to a preferred aspect of the present invention, since the lifting means includes the wire portion and the elastic portion, the lifting means expands and contracts when the position of the heater is changed, and the heater is lifted by the lifting means. However, the position of the heater can be easily changed. One of the wire part and the elastic part is attached in the vicinity of the heater, the other of the wire part and the elastic part is attached below the holding part, and the lifting means is connected to the heater via the upper part of the holding part. Since it is stretched between the vicinity and the lower part of the holding portion, the lifting means does not interfere with the heater position change, and the heater position change can be made easier.

  According to the more preferable configuration of the present invention, since the horizontal column can be expanded and contracted in the longitudinal direction of the horizontal column, the magnitude of the moment in the moving fixed portion by the lifting force can be adjusted. In addition, by extending the horizontal struts in the longitudinal direction, the moment at the moving fixed part due to the lifting force can be increased, and the load on the operator when changing the position of the heater can be further reduced. It is possible to make it easier to change the position.

  According to a further preferred configuration of the present invention, the longitudinal struts are erected vertically on the base, and the moving fixed part holds the transverse struts perpendicular to the longitudinal struts, so that force balance is achieved. Can be set easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 4, a paint drying apparatus 1 as a paint drying apparatus according to an embodiment of the present invention includes a heater device 10 and a support device 20 that supports the heater device 10. The paint drying apparatus 1 is used, for example, for drying paint applied to a metal such as a car body.

  The heater device 10 includes, for example, three heaters 11, 12, and 13. The number of heaters provided in the heater device 10 is not limited to this, and may be one or plural. The heaters 11, 12, and 13 are conventionally known heaters. For example, the heaters 11, 12, and 13 have the same shape and the same size, rectangular casings 11a, 12a, and 13a, and infrared heating elements 11b, 12b, and 13b provided in the casings 11a, 12a, and 13a, respectively. With each. The three heaters 11, 12, and 13 are attached to a pair of left and right strip-shaped connection frames 14a and 14b on both side surfaces. The heaters 11, 12, and 13 are attached to the connection frames 14a and 14b at equal intervals in the lateral direction perpendicular to the longitudinal direction. Further, the heater device 10 includes a connection frame 15 for connecting the heater device 10 to the support device 20. As shown in FIG. 4, the connection frame 15 includes a long piece 15a and a pair of short pieces 15b and 15c connected to both ends of the long piece 15a, and the shape thereof is substantially U-shaped. The free ends of the short pieces 15b and 15c are attached to the substantially central portions in the longitudinal direction of the connecting frames 14a and 14b. In the connection frame 15, the long piece 15 a is parallel to the longitudinal direction of the heaters 11, 12, 13, and the short pieces 15 b, 15 c are parallel to the heat radiation direction of the heaters 11, 12, 13 (arrow a direction in FIGS. 2 and 3). Further, it is fixed to the connection frames 14a and 14b. The connection frame 15 may be rotatably attached to the connection frames 14a and 14b. In this case, the heat dissipation direction of the heaters 11, 12, and 13 can be changed to an arbitrary direction.

  The support device 20 includes a rectangular base 21 for fixing the coating material drying apparatus 1 to the ground, a vertical column 22 erected perpendicularly to the base 21, and a holding unit 30 that holds the heater device 10. Prepare. Wheels 23 that enable the paint drying apparatus 1 to move are attached to the four corners of the base 21. The vertical column 22 is a straight bar-like member, and a pulley 24 around which a lifting portion 33 (described later) is stretched is pivotally supported at the upper end thereof.

  The holding unit 30 includes a movement fixing unit 31 attached to the vertical column 22 so as to be slidable in the vertical direction (the arrow b direction in FIGS. 2 and 3) along the vertical column 22, and the heater unit 10. The horizontal support | pillar 32 connected with 31 and the lifting part 33 which lifts the heater apparatus 10 upward are provided. The movement fixing part 31 has, for example, a hollow cylindrical shape, and in the coating material drying apparatus 1, the vertical column 22 is disposed through the hollow part. In addition, the movement fixing unit 31 includes a fixing device 34, and the fixing device 34 enables the movement fixing unit 31 to be fixed in the vertical column 22. The fixing device 34 is a conventionally well-known device. For example, the fixing device 34 is a fixing bolt. The fixing device 34 is screwed into a screw hole provided in the moving fixing portion 31 and tightened to thereby fix the moving fixing portion 31 to the vertical column 22. Make it fixable.

  Thus, in the paint drying apparatus 1, the movement fixing unit 31 is configured to be able to fix the heater device 10 at an arbitrary position in the vertical direction.

  As shown in FIG. 3, the lateral column 32 is a straight bar-shaped member, and one end is attached to the longitudinal center of the long piece 15 a of the connection frame 15 of the heater device 10. It is attached. The horizontal column 32 extends parallel to the heat dissipation direction of the heater of the connection frame 15, and is attached to the movable fixing unit 31 so as to be orthogonal to the vertical column 22. Moreover, the horizontal direction support | pillar 32 is comprised by the conventionally well-known structure in the longitudinal direction (heat dissipation direction) so that expansion-contraction is possible. For example, as shown in FIG. 3, the horizontal column 32 includes a hollow cylindrical guide casing 32a, a column 32b extending in the heat dissipation direction, and a fixing device 32c. In the paint drying apparatus 1, the guide casing 32 a is fixed to the movement fixing unit 31 so as to open in the heat dissipation direction. One end of the column 32b is fixed to the connection frame 15 as described above, and is slidably disposed in the hollow portion of the guide casing 32a. Thereby, the support | pillar 32b can move in the guide casing 32a in a heat radiating direction, and the horizontal support | pillar 32 can be expanded-contracted in parallel with the heat radiating direction of a heater. The fixing device 32c is a conventionally known device like the fixing device 34 of the movable fixing portion 31, and is, for example, a fixing bolt that is screwed into a screw hole provided in the guide casing 32a and tightened. Thus, the support column 32b, that is, the heater device 10 can be fixed to the guide casing 32a, that is, to the vertical support column 22. Note that the horizontal column 32 may not be extendable.

  Thus, in the paint drying apparatus 1, the horizontal column 32 is configured to be expandable and contractable in the heat dissipation direction, and is configured to be able to fix the heater device 10 at an arbitrary position in the heat dissipation direction.

  The lifting portion 33 is a string-like member, and includes a wire portion 35 made of a wire and an elastic portion 36 made of an elastic body. Specifically, the wire part 35 is made of a metal wire, the elastic part 36 is made of, for example, a coil spring, and one end of the wire part 35 and the elastic part 36 are joined to each other. The wire portion 35 is not limited to a metal wire, and may be a wire made of another material. The elastic portion 36 is not limited to a coil spring, and may be another elastic body such as a helical spring or rubber.

  In the paint drying apparatus 1, the other end of the wire portion 35, that is, one end 33 a of the lifting portion 33 is attached to the lateral column 32, and the other end of the elastic portion 36, that is, the other end 33 b of the lifting portion 33 is attached to the base 21. ing. Further, the wire portion 35 is stretched around the pulley 24 of the vertical column 22. As shown in FIGS. 2 and 3, the lifting portion 33 is stretched between the lateral column 32 and the base 21 via the pulley 24, and the elastic force of the elastic portion 36 is transverse. It acts on the support column 32, and the horizontal support column 32, that is, the heater device 10 is lifted upward, more specifically, in the direction of the wire portion 35. The wire part 35 and the elastic part 36 are formed in a predetermined length, and are set so that a desired lifting force acts at an arbitrary position of the heater device 10 in the vertical direction.

  One end 33 a of the lifting portion 33 is attached to the tip 37 of the column 32 b of the lateral column 32. In this way, the one end 33a of the lifting portion 33 is attached to the position farthest from the vertical column 22 in the column 32b of the horizontal column 32, so that the periphery of the movable fixing unit 31 generated by the lifting force of the lifting unit 33 is provided. The moment can be increased. For this reason, the load which acts on the movement fixing | fixed part 31 by the load of the heater apparatus 10, specifically between the fixing apparatus 34, the movement fixing | fixed part 31, and the vertical direction support | pillar 22, and between the horizontal direction support | pillar 32 and the vertical direction support | pillar 22 Can be reduced. Also, with this configuration, as will be described later, it is possible to reduce the burden on the operator when the heater device 10 is moved in the vertical direction.

  As the attachment position of the one end 33a of the lifting portion 33 is farther from the vertical column 22, the effect of the lifting portion 33 can be further increased. That is, this effect can be achieved even if the attachment position of the one end 33 a of the lifting portion 33 is not the tip 37 of the lateral column 32. Accordingly, the attachment position of the one end 33a of the lifting portion 33 is not limited to the tip 37 of the horizontal column 32, but the position of the vertical column 22 side from the tip 37 of the horizontal column 32, the connection frame 15, the heater 11, The vicinity of the heater device 10 such as 12, 13 may be used. The attachment position of the one end 33 a of the lifting portion 33 is most preferably in the vicinity of the heater device 10. When the attachment position of the one end 33a of the lifting part 33 is the horizontal column 32, the strength of the paint drying apparatus 1 can be improved.

  Next, the operation of changing the vertical position of the heater device 10 in the paint drying apparatus 1 having the above-described configuration will be described.

  First, the operator releases the fixation of the movement fixing unit 31 by the fixing device 34 of the movement fixing unit 31 and enables the movement fixing unit 31 to move in the vertical direction. Then, the operator holds the heater device 10 and moves the heater device 10 to a desired position in the vertical direction. At this time, due to the weight of the heater device 10, a frictional force is generated between the movable fixing portion 31 and the vertical support column 22, and the operator slides the movable fixing portion 31 against the frictional force to heat the heater. The apparatus 10 will be moved.

  Here, as described above, in the horizontal column 32, the heater device 10 is lifted upward by the lifting portion 33 in the direction opposite to the weighting direction of the heater device 10, and is fixed when the heater device 10 moves. The frictional force between the part 31 and the vertical column 22 can be reduced. In addition, the lifting portion 33 is attached to the tip 37 of the column 32 b that is the farthest position from the vertical column 22 in the horizontal column 32, and the moment generated in the movable fixing unit 31 by the lifting force of the lifting unit 33 is increased. can do. Accordingly, the moment acting on the movable fixing portion 31 due to the load of the heater device 10 can be greatly reduced or offset, and the movement between the movable fixing portion 31 and the vertical column 22 generated when the heater device 10 moves. The frictional force can be greatly reduced or offset. For this reason, the force that resists the frictional force required when moving the heater device 10 is reduced or eliminated, and the operator's force required for moving the heater device 10 is reduced, which is applied to the operator. The load can be further reduced, and the heater position can be changed more easily.

  As described above, according to the paint drying apparatus according to the embodiment of the present invention, the lifting device 33 is located near the heater device 10 away from the movable fixing unit 31 (vertical column 22). Since it is lifted, the moment generated in the movable fixing part 31 by the lifting force of the lifting part 33 can be increased. For this reason, when the position of the heater device 10 is changed, the frictional force generated between the movable fixing unit 31 and the vertical column 22 by sliding along the vertical column 22 of the movable fixing unit 31 can be efficiently reduced. Or can be deleted. Therefore, it is possible to reduce the load applied to the operator when the position of the heater device 10 is changed, and to easily change the position of the heater device 10. In addition, since the moment generated in the movable fixing portion 31 by the lifting force of the lifting portion 33 can be increased, the force required to change the position of the heater device 10 can be further reduced with a smaller lifting force.

  Further, since the lifting portion 33 lifts the heater device 10, it is possible to reduce the frictional force generated when the position of the heater device 10 is changed, and the operator's force necessary for changing the position of the heater device 10 can be reduced. It can be further reduced. For this reason, the load applied to the operator when the position of the heater device 10 is changed can be further reduced, and the position change of the heater device 10 can be made easier.

  In addition, since the lifting portion 33 includes the wire portion 35 and the elastic portion 36, the lifting portion 3 expands and contracts when the position of the heater device 10 is changed, so that the heater device 10 is lifted by the lifting portion 33. However, the position of the heater device 10 can be easily changed.

  The lifting portion 33 has one end 33 a attached to the horizontal column 32 and the other end 33 b attached to the base 21. The lifting portion 33 is connected to the horizontal column 32 via a pulley 24 attached to the upper portion of the vertical column 22. Since it is stretched between the base 21, the lifting portion 33 does not interfere with the position change of the heater device 10, and the position change of the heater device 10 can be made easier.

  In the embodiment of the present invention, one end of the elastic portion 36 is attached to the base 21, but the attachment position of one end of the elastic portion 36 is not limited to this. For example, one end of the elastic portion 36 may be attached to the vertical column 22. In the embodiment of the present invention, one end of the wire portion 35 and one end of the elastic portion 36 are attached to the lateral column 32 and the base 21, respectively. One end of each may be attached to the base 21 and the lateral column 32.

  Further, since the horizontal column 32 can be expanded and contracted in the longitudinal direction (heat radiation direction) of the horizontal column 32, the magnitude of the moment in the movable fixing unit 31 generated by the lifting force of the lifting unit 33 can be adjusted. In addition, by extending the horizontal column 32 in the longitudinal direction, it is possible to increase the moment in the moving fixed portion 31 due to the lifting force of the lifting portion 33, and the load applied to the operator when the position of the heater device 10 is changed. Can be reduced, and the position of the heater device 10 can be changed more easily.

  Furthermore, since the vertical column 22 is erected vertically on the base and the movable fixing unit 31 holds the horizontal column 32 so as to be orthogonal to the vertical column 22, the balance of force can be easily set. can do.

  In the embodiment of the present invention, one end of the elastic portion 36 is attached to the base 21, but the attachment position of the one end of the elastic portion 36 is not limited to this. For example, one end of the elastic portion 36 may be attached to the vertical column 22.

  Further, the vertical column 22 is erected on the base 21 vertically, and the movable fixing unit 31 holds the horizontal column 32 so as to be orthogonal to the vertical column 22. 22 and the positional relationship of the horizontal direction support | pillar 32 are not restricted to this.

  Furthermore, the present invention is not limited to the above-described embodiment of the present invention, and the material, dimensions, configuration, and the like may be arbitrarily changed.
