Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hanging type drying apparatus suitable for use in an automobile repair shop or the like.

[Prior Art] Conventionally, a coating operation includes a coating step such as spraying and a drying step of drying a coated product (hereinafter referred to as a work).

In order to obtain high quality coated products, it is important to maintain uniform and stable drying temperature and drying time as basic conditions in the drying process, as well as to improve the uniformity and adhesion of the coating film in the coating process. is there. For example, in the case of an automobile body coated with a cationic paint, the drying temperature is 180 ° C and the drying time is 20 minutes.

By the way, in a workplace where a large amount of work (vehicle body) is entirely coated with high quality like an automobile manufacturing plant, a large-scale dedicated drying facility as shown in Japanese Utility Model Publication No. 59-6397 is usually provided. However, in a work place where a small amount of work is mostly partially painted, such as in an automobile repair shop, installing a dedicated drying facility will impose a heavy burden on the facility economy and installation space. Too much.

Therefore, in an automobile repair shop or the like, as shown in FIG. 2, every time the work W is dried, a mobile drying device 50 equipped with a hot air lamp 51 or the like is brought from the storage location to the work W, and the local area is locally moved. It is heating.

[Problems to be solved by the invention] However, in this case, a transport space and a storage space for moving the mobile drying device 50 must be specially secured in the work place, which is effective in terms of facility economy and work space. It is disadvantageous in use.

Further, since the work W is locally heated, it is difficult to uniformly dry the coated portion of the work W at a predetermined temperature for a predetermined time, and problems such as discoloration often occur. Therefore, especially when the entire surface of the work W is dried, it is impossible to guarantee a predetermined coating quality.

A problem similar to the above also occurs in a factory where a large number of products are manufactured and only a specific part is painted.

An object of the present invention is to provide a hanging-type coating drying apparatus which is excellent in facility economy and handleability, can effectively utilize a work space, and can be easily used at the time of use.

[Means for Solving the Problems] In the present invention, in a work place where a large amount of works are not dried, such as in an automobile repair shop, the arrangement of the drying device is limited to a flat space. It is the same as the above, and it is reconfirmed that it is disadvantageous in terms of equipment economy and effective use of work space, and that the local heating method cannot guarantee the prescribed coating quality. It is sometimes formed so that it can be hung on the ceiling of an empty space.

That is, a furnace body unit including a furnace body, a hot air generating means, and a hot air circulating means, which is formed so as to be able to be hung above an upper part of a work place when not in use, and this furnace body unit is arranged at a lower part of the work place when used. Elevating means for lowering the work so as to accommodate the work and raising it to the upper part after the drying process.

[Operation] In the present invention, when a work is dried, the furnace body unit is lowered from the upper portion (for example, the ceiling) of the work space by using the elevating means to accommodate the work in the furnace body of the unit. Next, the hot air generating means and the hot air circulating means of the furnace unit are driven to blow hot air to the work to dry it at a predetermined temperature for a predetermined time. After the work drying process,
Use the lifting means to move the furnace unit to the upper part of the void (ceiling)
Lift to.

Therefore, the work is not limited to a flat space, but the three-dimensional space is positively used to dry the work. Therefore, the facility economy and the handleability are excellent, and the work space can be effectively used. Available.

[Embodiment] FIG. 1 is a view showing an embodiment of a hanging type coating drying apparatus according to the present invention.

The present embodiment is a drying device which is roughly divided into a furnace unit 10 and an elevating means 40 and is used in an automobile repair shop.

Here, the furnace body unit 10 includes a furnace body 11 and hot air generating means.
21 and the hot air circulation means 31, and is formed so that it can be hung on the upper part of the work place (the ceiling 9 in this embodiment) when not in use.

Here, the furnace body 11 is formed into an overall box shape with an open bottom 12 so that it can accommodate a work W that descends from the ceiling 9 and is located in the lower part of the work space (the floor surface 2 in this embodiment). Has been done. The volume of the furnace body 11 is the work W to be dried.
Of these, the ones with the largest external dimensions are selected to be accommodated.

The hot air generating means 21 is means for generating hot air to be supplied into the furnace body 11. In the present embodiment, the hot air generating means 21 includes a heater chamber 22 arranged above the furnace body 11.
And a heater using electric heat built in the heater chamber 22,
The heater and temperature control means for controlling the heater to maintain the indoor temperature at a predetermined temperature for a set time are not shown (the heater and the temperature control means are not shown in FIG. 1).

Further, the hot air circulation means 31 includes a blower 32 for sending the hot air generated in the heater chamber 22 into the furnace body 11, and a blower.
It includes a hot air blowing duct 33 for blowing the hot air sent from 32 into the furnace body 11, and a suction duct 34 for returning the hot air blown into the furnace body 11 to heat the work W to the heater chamber 22 again. Has been formed.

On the other hand, the elevating means 40 includes a wire 42 for suspending the furnace unit 10, and a ceiling hoist 41 for hoisting and lowering the wire 42 to ascend and descend the furnace unit 10.

The heater chamber 22 and the blower 32 described above are arranged on the furnace body 11 so as to be horizontal when suspended.

 Next, the operation will be described.

In order to dry the work W in an automobile repair shop, the work W is placed on the floor surface 2 portion directly below the furnace unit 10 suspended from the ceiling 9. Next, the elevating means 40 is driven to lower the furnace unit 10 and land it on the floor surface 2. Then, the work W is housed in the furnace body 11 in a state of being sealed by the furnace body 11 and the floor surface 2.
