DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for elevating and lowering a processed product in a steam drying apparatus.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional steam drying apparatus fills a processing tank 1 with a highly volatile medium 2 such as isopropyl alcohol and heats it with a heater 3 attached to the bottom to generate steam. The moisture adhering to the surface of the processing object 6 supported by the elevating frame 5 located above the drain pan 4 is replaced with the vaporized medium vapor, and furthermore, condensation due to the temperature difference between the processing object 6 and the medium vapor. As a result, the processed material 6 is dried.
I was The water or the like attached to the surface of the workpiece 6 had become as to flow out received by the drain pan 4.

Further, a cooling coil 7 is surrounded inside the upper portion of the processing tank 1 , and the medium vapor is condensed by the cooling coil 7 and received by a condensed liquid tray 8 provided below. It had become a way to flow out to the outside Te.

[0007] As shown in FIG. 7, the lifting frame 5 is provided at its lower end with a receiving table 9 for supporting the processing object 6, and at the upper end of the lifting frame 5 is provided a mounting plate 10 protruding on the opposite side of the receiving table 9. The rod 13 of the air cylinder 12 provided on the cylinder mounting plate 11 is mounted on the lower surface of the mounting plate 10, and guide shafts 14 and 15 are mounted on both sides of the rod 13.
Guide pipes 16 and 17 with 15 fixed to cylinder mounting plate 11
Inserted and had become so that is moved between by elevating the elevating frame 5 treated 6 the drying position and the processing tank 1 of the upper external mounting position by the drive of the air cylinder 12 in the.

[0005]

In the above-mentioned conventional apparatus, drying is carried out by the replacement of moisture adhering to the processing object with the medium vapor and the condensation effect due to the temperature difference. Therefore,
When inserting the treated product in the processing bath, it would be inserted inevitably elevator frame and pedestal also treatment tank. Therefore, even in the low temperature portions of the lifting frame and the receiving table and in the portion where moisture is attached, the replacement with the medium vapor and the condensation phenomenon occur. Come to, and the vapor medium at the lifting frame and pedestal
There is a problem that the consumption of the highly volatile medium increases by the amount of the replacement and condensation phenomena. Therefore, in the present invention,
Reduces the contact surface with medium vapor and reduces the consumption of highly volatile media
It is an object of the present invention to provide an apparatus for elevating and lowering a processed product in a steam drying apparatus, which suppresses the occurrence of the problem.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a lifting cable is mounted on a support for supporting a workpiece to be raised and lowered in a processing tank, and the lifting cable is driven by a winding motor. The evaporator is wound around a take-up drum to constitute a device for elevating and lowering a processed material in a steam dryer.

In addition, grooved wheels are mounted at four corners of a support for supporting a workpiece to be lifted and lowered in the processing tank, and the other end of the lifting cable fixed at one end is connected to the other end of the cable via grooved wheels perpendicular to the workpiece. The above problem has been solved by forming a device for lifting and lowering a processed material in a steam drying device by winding the product on a winding drum.

[0008]

SUMMARY OF] The present invention has the structure described above, the winding and the winding of the lift cable by the driving of the winding motor
The pedestal supporting the processed object is moved up and down by returning . Further, one end of the lifting cable is fixed, by winding the winding drum via the grooved wheels mounted on the pedestal, causing the temperature descending the cradle by driving and self-weight of the winding drum.
