  A drying apparatus provided with such a heater unit 2d instead of the heater unit 2a or the heater unit 2b is also included in the drying apparatus according to the present invention.

  When the heater unit 2d is provided in place of the heater unit 2a or the heater unit 2b, the heating capacity of each of the pair of heater units 2d and 2d located at the outermost portion is such that the outermost portion is heated. It becomes larger than the heating capacity of the heater unit (in this example, each of the heater units 2c1 and 2c2) provided inside the pair of heater units 2d and 2d, and the temperature at the boundary between the atmosphere and the hot air is lowered. Since the temperature of the part can be raised efficiently, the painted surface of various articles can be dried uniformly and efficiently.

  Moreover, in this drying apparatus 1, since the blower means which has a turbo fan is used as the air source 3, when using compressed air, the temperature of compressed air rises by a blower means.

That is, in this drying apparatus 1, since the compressed air whose temperature has risen is further heated by the heater means, the painted surfaces of various articles can be dried with high energy efficiency.
(Embodiment 2 of the invention)
Hereinafter, an example of a drying apparatus with a paint gun according to the present invention will be described in more detail with reference to the drawings.

  FIG. 9 is a side view schematically showing an example of a drying apparatus with a paint gun according to the present invention.

  Since this drying apparatus with a paint gun 1A has the same configuration as the drying apparatus 1 except for the following configuration, it corresponds to a member apparatus that constitutes the drying apparatus 1 among the member apparatuses that constitute the drying apparatus with a coating gun 1A. The member device to be attached is denoted by the same reference numeral as that of the member device constituting the drying device 1, and the description thereof is omitted.

  This coating gun-equipped drying device 1A can be connected to a coating gun 61.

  Further, in the drying apparatus with a paint gun 1A, an air switching chamber 10A is used instead of the air distribution chamber 10.

  FIG. 10 (a) shows a side view schematically showing the vicinity of the air switching chamber 10A in an enlarged manner, and FIG. 10 (b) shows the air switching chamber 10A shown in FIG. 10 (a). It is a top view which shows roughly the state which looked at the vicinity in the downward direction from the upper position.

  The air switching chamber (two-way switching means) 10 </ b> A includes an air distribution chamber 41.

  The air distribution chamber 41 includes an air supply port h42a, an air discharge port h42b connecting the air supply tube T1, an air discharge port h42c connecting the air supply tube T2, an air discharge port h42d connecting the air supply tube T3, and an air supply. An air discharge port h42e for connecting the tube T4 and an air supply tube connection port (second air discharge port) h42f for connecting an air supply tube T10 for supplying compressed air to the coating gun 61 are provided.

  In this specification, the air outlet h42b, the air outlet h42c, the air outlet h42d, and the air outlet h42e are all connected to the air outlet nozzles 24. The discharge ports h42b, h42c, h42d, and h42e are collectively referred to as a first air discharge port.

  The air switching chamber (two-way switching means) 10 </ b> A includes an operation lever 42.

  The operation lever 42 is provided to be rotatable about a rotation shaft 42ax.

  Further, immediately below the operation lever 42, the air source 3 and the first air discharge port (air supply pipes T1, T2, T3, T4) are in a non-conductive state, and the air source 3 and the air supply pipe are provided. The connection port (second air discharge port) h42f (air supply pipe T10) is in a conductive state or the air source 3 and the first air discharge port (air supply pipes T1, T2, T3, T4) And a switching valve 43 for making the air source 3 and the air supply pipe connection port (second air discharge port) h42f (air supply pipe T10) non-conductive. The air distribution chamber 41 is provided.

  The drying apparatus with a paint gun 1A includes an air switching chamber (two-way switching means) 10A. Therefore, the operation lever 42 of the air switching chamber (two-way switching means) 10A is operated to switch the switching valve 43 to the air source 3. Between the air source 3 and the first air discharge port (air supply pipes T1, T2, T3, T4), and the air source 3 and the air supply pipe connection port (second air discharge port) h42f (air supply) If the tube T10) is not electrically connected, it can be used as a drying device.

  Further, since the drying apparatus with a paint gun 1A includes an air switching chamber (two-way switching means) 10A, the operation lever 42 of the air switching chamber (two-way switching means) 10A is operated to switch the switching valve 43 to the air. Between the air source 3 and the first air discharge port (air supply pipes T1, T2, T3, T4), and the air source 3 and the air supply pipe connection port (second air discharge port) h42f. If it is in a conductive state with (air supply pipe T10), it can be used as a coating apparatus.

  This drying device 1A with a coating gun is used to perform coating of various articles using a coating gun 61 with one device by switching operation of the two-way switching unit of the air switching chamber (two-way switching unit) 10A, Since the painted surfaces of various articles can be dried using the units 2a, 2b, 2c1, and 2c2, the painting operation and the subsequent drying operation of the painted surfaces can be performed efficiently.

  As shown in FIGS. 10A and 10B, in this drying apparatus with a paint gun 1A, the air connecting between the air source 3 and the air switching chamber (two-way switching means) 10A. A through hole ht0a is provided in the middle position of the supply pipe T0A (in this example, a position above the middle position of the air supply pipe T0A), and the pressure adjusting means 51 is provided so as to cover the through hole ht0a.

  The pressure adjusting means 51 includes a housing 52 and a pressure adjusting member 53 accommodated in the housing 52.

  The case 52 includes a through hole h52 for conducting between the inside of the case 52 and the atmosphere.

  As the pressure adjusting member 53, for example, a fibrous material that conducts air but has air resistance (for example, cotton) is used.

  The drying device with a paint gun 1A includes the pressure adjusting means 51. For example, the operating lever 42 of the air switching chamber (two-way switching means) 10A is operated to switch the switching valve 43 between the air source 3 and the first. The air discharge port (air supply pipes T1, T2, T3, T4) is in a non-conductive state, and the air source 3 and the air supply pipe connection port (second air discharge port) h42f (air supply pipe T10) When the coating gun 61 is not used when used as a coating apparatus, when the air pressure in the air supply pipe T10 becomes a predetermined air pressure or higher, the pressure adjusting means 51 Is released into the atmosphere, the air pressure in the air supply pipe T10 is always maintained at a constant pressure.

  That is, if the type and amount of the pressure adjusting member 53 accommodated in the casing 52 are adjusted so that the air pressure in the air supply pipe T10 becomes the optimum air pressure for the painting work, the use of the coating gun 61 is started. Since a large amount of air is not released from the coating gun 61, the painting operation of the coated surfaces of various articles can be performed in an optimum state.

  Since the drying apparatus according to the present invention can efficiently dry the coated surface of various articles that have been coated, it can be widely used in the field of coating.
