Now, when polishing the application section 3 of the squeegee 1 with the polishing device 6 of the squeegee 1 having the above-described configuration, first, the handle 88 of the longitudinal movement adjustment section 53 is rotated to rotate the lead screw 87. , the slide member 83 is slid on the slide base 81 and retreated, and the abrasive part 5 held above the slide member 83 via the lifting block 91, the holding stand 73, and the holding frame 60 is moved above the holding part 2 of the squeegee 1. Make them retreat further.

After that, the clamp cylinder 28 of the holding part 2 is operated to move the clamping arm 26 back and forth, and the clamping plate 27 is moved back and forth.
is separated from the holding plate 24a of the holder main body 24.

As shown in FIG. 7b, the squeegee 1 fitted into the squeegee holder 8 made of an aluminum frame is placed on the upper side of the movable base 30 while abutting against the holding piece 32 of the movable base 30, and the squeegee 1 is applied. The part 3 is connected between the clamping plate 24a of the holder main body 24 and the clamping plate 2.
7, the clamp cylinder 28 is operated again to move the clamping arm 26 backward to hold the squeegee 1 with its squeegee holder 8 in contact with the holding piece 32, and also to hold the squeegee 1 at the application portion of the squeegee 1. The tuyeres of No. 3 can be corrected and held while being clamped from both left and right sides via the clamping plates 24a and 27 over their entire length.

Note that the clamping plates 24a and 2 of the application section 3 of the squeegee 1
The holding position of the holder 7 can be arbitrarily adjusted by rotating the adjustment screw 22 and moving the holder main body 24 up and down via the guide shafts 20 on both left and right sides.

Therefore, after the holding part 2 has finished holding the squeegee 1, the handle 88 is rotated again to move the slide member 83 forward on the slide base 81, thereby causing the abrasive part 2 to hold the squeegee 1. Return it to the upper side of the holding part 2.

Then, the motor 99 of the vertical adjustment movement section 54 of the polishing section 2 is started, and the rotation shaft 97 and the rotation gear 94 are rotated.
The lifting block 91 is lowered by rotating the lifting screw lever 92 via the lifting screw lever 92, and in conjunction with the lowering movement of the lifting block 91, the drive motor 65 of the rotating part 52 is started, and the driving roll 61, tension roll 62a, 62b The endless sandpapers 50 and 51 are rotated via the abrasive contact roll 64 and the positioning roll 63, and the motor 47 of the moving part 4 of the holding part 2 of the squeegee 1 is started, and the chain belt 44 and the connecting member connected thereto are started. The moving platform 30 is connected to the slide rail 4 via 45.
It is caused to reciprocate back and forth between the front and rear ends of 2.

Therefore, by lowering the lifting block 91, the endless sandpaper 50 or 51 is brought into pressure contact with the polished portion of the application section 3 reciprocated by the movable section 4 via the polishing contact roll 64, thereby accomplishing the desired polishing. can do.

In addition, when polishing the application part 3 of the squeegee 1 by the polishing part 5, the holding parts 24a and 2 of the holding part 2 are
7, polishing can be performed while correcting the deformation of the application section 3, and the polishing liquid is supplied from the tank 112 to the endless sandpaper 50 or 51 through the nozzle 111 of the supply section 7. As a result, it is possible to prevent heat generation in the application section 3, and also to prevent the abrasive surface of the endless sandpaper 50 or 51 from being clogged with abrasive powder, thereby eliminating the conventional drawbacks such as burning and clogging. Defects can be eliminated.

Furthermore, in the rotating part 52 of the polishing part 5, two endless sandpapers 50 and 51 are stretched, and for example, the endless sandpaper 50 is used as the endless sandpaper for rough polishing, and the endless sandpaper 51 is used as the endless sandpaper for rough polishing. By using the endless sandpaper for finish sanding, rough sanding and finish sanding can be performed continuously without the need to change the endless sandpaper.

This switching operation between the endless sandpapers 50 and 51 is carried out while the polishing section 5 is moved forward or backward via the forward/backward motion adjustment moving section 53 of the polishing section 5.

That is, by rotating the rotary handle 88, the lead screw 87 is rotated, and as the lead screw 87 is rotated, the connecting member 84 that is threaded thereon is threaded.

Therefore, due to the screwing of the connecting member 84, the slide member 83 slides on the upper side of the slide base 81 while moving forward or backward according to the screwing direction of the connecting member 84, causing the polishing section 5 to move forward or backward. You can force it.

By moving the polishing section 5 in the front-back direction, the endless sandpapers 50 and 51 are switched to the applicator section 3 of the squeegee 1.

In addition, the operation of reciprocating the holding part 2 of the squeegee 1 via the moving part 4 when polishing the application part 3 of the squeegee 1 with the endless sandpapers 50 and 51, and the endless sandpaper 50 of the polishing part 5, 51
The relationship between the polishing operations can be controlled by a proximity switch 77.

That is, the reciprocating motion of the movable table 30 in the movable section 4 is achieved by starting the motor 47 and moving the drive pulley 4.
8. Sprocket 43 via sprocket 46
By rotating the frame 41, the movable base 30 is moved while running on a chain belt 44. Switching between forward and backward movement is via limit switches (not shown) installed at the forward and reverse ends of the base 41. This is accomplished by rotating the motor 47 forward and reverse.

This traveling movement of the moving table 30 also causes the squeegee 1 to move.
When the abrasive surface pushes the abrasive contact roll 64 upward, the proximity switch 77 detects this and
The reciprocating movement of the moving table 30 in the moving unit 4 continues, and the polished surface of the squeegee 1 is polished by a predetermined amount,
Proximity switch 77 detects when the polishing control 64 has lost its height to be pushed upward;
The rotational drive of the motor 47 in the moving unit 4 is stopped via the detection signal.

Furthermore, the polishing position in the polishing part 5 and the holding part 2 of the squeegee 1 is adjusted by moving the polishing part 5 in the front and back direction by the longitudinal adjustment movement part 53 and by moving the polishing part 5 in the vertical direction by the vertical movement adjustment movement part 54. This is accomplished by the movement operation of the polishing section 5 and the rotation operation of the polishing section 5 by the rotation (angle) adjustment movement section 55.

That is, the operation in the front and back direction can be performed by the same operation as the back and forth movement operation in the switching operation of the endless sandpapers 50 and 51 described above, and the movement operation in the up and down direction can be performed roughly by driving the motor 99. In addition to dynamic adjustment, fine adjustment can be performed using the rotating handle 98.
By rotating the rotary handle 98, the lifting screw rod 92 is rotated via the gear 94, and the connecting member 93 that is threaded thereon is screwed in the vertical direction, and the lifting block 9 is moved through the connecting member 93.
The polishing section 5 can be raised and lowered via the holding frame 60 by raising and lowering the polishing section 1 along the raising/lowering guide frame 90.

In addition, for rotation operation, the rotary handle 10
3, the holding frame 60 can be rotated in the front and rear directions in FIG. be able to.

In addition to the positioning of the polishing position by the front-back, up-down and angle adjustment operations of the polishing unit 5, the tension roll 62 and the contact roll 64 of the rolls 61, 62, 63 and 64 of the rotating unit 52 are
It is also possible to set the position by adjusting each roll of the positioning roll 63 and adjusting the height position of the holding portion 2 of the squeegee 1 .

The height position of the holder can be adjusted by rotating the adjustment screw 22.
This is performed while moving up and down in the up and down direction via the guide shaft 20.

The polishing position of the endless sandpaper 50, 51 of the polishing section 5 with respect to the polishing surface of the squeegee 1 held in the holding section 2 can be set by each operation in each part described above. The polishing position can be set in the same manner for the operation for polishing the squeegee 1.

Now, after completing the rough polishing and finishing polishing of the application part 3 of the squeegee 1 with the endless sandpaper 50, 51 in the above, after stopping the movable part 4, the polishing part 5 is moved upward and retreated backward. The polishing work of the squeegee 1 can be completed by operating the clamp cylinder 28 of the holding part 2 to release the clamping of the application part 3 between the holding plates 24a and 27 and removing the squeegee 1 from the holding part 2. The next polishing process of the squeegee 1 can be performed using the same working procedure.

Incidentally, regarding the polishing work of the squeegee 1, automatic polishing work of the squeegee 1 can be made possible by operating each part in a related manner.

[Effect of the invention] As is clear from the above explanation, according to the present invention,
Appropriate polishing of the applied area can be performed without being affected by deformation of the applied area caused by the use of a squeegee.

Further, the adjustment work of the application section and the polishing part of the squeegee and the switching work of the polishing work can be simplified and speeded up, and the polishing work of the squeegee can be performed appropriately.
