Abstract

A dryer for increasing the dryness by fixing the inside of a bowl-shaped workpiece toward a rotating table side is provided.
A dryer for drying an object includes a rotatable hollow cylindrical rotation shaft, a center shaft supported inside of the rotation shaft via a bearing and does not rotate, the center shaft having an inner blow passage therein extending along the center shaft, a rotation plate fixed to the first end of the rotation shaft; an inner fixed nozzle extending along the first end of the rotation shaft from the center shaft, a jig disposed on the rotation plate for fixing the object, a drive motor for rotating the rotation shaft, and a blower connected to the inner blow passage.

First claim

What is claimed is:

1. A dryer for drying an object, comprising:
a hollow cylindrical rotation shaft configured to rotate;
a center shaft supported inside of the rotation shaft via a bearing, the center shaft configured not to rotate, the center shaft having an inner blow passage therein extending along the center shaft;
a rotation plate fixed to a first end of the rotation shaft;
an inner fixed nozzle extending along the first end side of the rotation shaft from the center shaft;
a jig disposed on the rotation plate for fixing the object;
a drive motor configured to rotate the rotation shaft;
a blower connected to the inner blow passage;
a housing slidably fixed to an outer surface of the rotation shaft at a second end that is different from the first end;
a compressed air source;
an annular passage extending circumferentially between the housing and the rotation shaft;
a first passage connecting the annular passage and the compressed air source; and
a second passage extending inside the rotation shaft in a shaft direction, the second passage connecting to the annular passage, the second passage having an opening at the first end of the rotation shaft,
wherein the jig includes
a clamp having an air cylinder, and
a third passage connecting the second passage and the air cylinder.

2. The dryer according to claim 1 , wherein
the inner fixed nozzle includes a cylindrical pipe-shaped body extending along the rotation shaft and having a closed end at one end, the inner fixed nozzle having a slit extending along the rotation shaft.

3. The dryer according to claim 2 , wherein
the slit extends from a basal end fixed to the center shaft to around a distal surface of the body.

4. The dryer according to claim 1 , wherein
the rotation shaft rotates at a rotational speed of 200 to 500 rpm.

5. The dryer according to claim 1 , further comprising:
an outer blow nozzle arranged outside a closed area occupied by rotating the rotation plate, the object and the jig, the outer blow nozzle facing the object.

6. The dryer according to claim 1 , wherein
the rotation plate has an opening exposing a blow object portion of the object from the rotation plate when the object is mounted on the rotation plate.

7. The dryer according to claim 1 , further comprising:
a drive toothed pulley;
a driven toothed pulley; and
an endless toothed belt stretched between the drive toothed pulley and the driven toothed pulley,
wherein the drive motor is a servo motor.

8. The dryer according to claim 2 , wherein
the rotation shaft rotates at a rotational speed of 200 to 500 rpm.

9. The dryer according to claim 3 , wherein
the rotation shaft rotates at a rotational speed of 200 to 500 rpm.

10. The dryer according to claim 2 , further comprising:
an outer blow nozzle arranged outside a closed area occupied by rotating the rotation plate, the object and the jig, the outer blow nozzle facing the object.

11. The dryer according to claim 3 , further comprising:
an outer blow nozzle arranged outside a closed area occupied by rotating the rotation plate, the object and the jig, the outer blow nozzle facing the object.

12. The dryer according to claim 4 , further comprising:
an outer blow nozzle arranged outside a closed area occupied by rotating the rotation plate, the object and the jig, the outer blow nozzle facing the object.

13. The dryer according to claim 2 , wherein
the rotation plate has an opening exposing a blow object portion of the object from the rotation plate when the object is mounted on the rotation plate.

14. The dryer according to claim 3 , wherein
the rotation plate has an opening exposing a blow object portion of the object from the rotation plate when the object is mounted on the rotation plate.

15. The dryer according to claim 4 , wherein
the rotation plate has an opening exposing a blow object portion of the object from the rotation plate when the object is mounted on the rotation plate.

16. The dryer according to claim 5 , wherein
the rotation plate has an opening exposing a blow object portion of the object from the rotation plate when the object is mounted on the rotation plate.

17. The dryer according to claim 2 , further comprising:
a drive toothed pulley;
a driven toothed pulley; and
an endless toothed belt stretched between the drive toothed pulley and the driven toothed pulley,
wherein the drive motor is a servo motor.

18. The dryer according to claim 3 , further comprising:
a drive toothed pulley;
a driven toothed pulley; and
an endless toothed belt stretched between the drive toothed pulley and the driven toothed pulley,
wherein the drive motor is a servo motor.

19. The dryer according to claim 4 , further comprising:
a drive toothed pulley;
a driven toothed pulley; and
an endless toothed belt stretched between the drive toothed pulley and the driven toothed pulley,
wherein the drive motor is a servo motor.
