DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating apparatus having a movable coating apparatus.

[0002]

2. Description of the Related Art A method of coating or impregnating a web made of paper, plastic film, metal foil, or the like with a coating agent includes:
There are various methods such as a roll coating method, a knife coating method, a die coating method, and a deep coating method. The coating equipment is prepared in advance with a number of dedicated coating devices corresponding to the desired coating type so that it can support these various coating types, and the coating is performed according to the change of the coating type. In some cases, the processing device can be replaced, and an unwinding device, a drying device, a winding device, and the like arranged in the coating facility are used as they are.

Conventionally, this coating device can be replaced manually by a worker when the coating device is small and very light. However, when the coating device is large and heavy, a winding machine is used. You need to do it.

[0004] However, when the coating device is exchanged using the winder, the guide rail for the winder is extended from above the coating device installation area in the coating equipment to above the coating device storage space. Required, and coating equipment is subject to restrictions for installing guide rails. Further, when the hoist is operated, dust such as metal powder is generated from a moving mechanism of the hoist, etc., so that it is not possible to cope with coating equipment in a clean environment in which dust needs to be reduced extremely.

[0005] In order to solve the above-mentioned problems, the applicant of the present application has proposed a coating apparatus which can be easily moved without using a winding machine in the prior application of Japanese Patent Application No. 7-122916. . This movable coating device 31
As shown in the front view of FIG. 5, the plan view of FIG. 6, and the bottom view of FIG. 7, a total of four floating tools 7 are disposed near the four corners on the bottom surface 32a side of the apparatus main body 32. A restraining wheel 16 is provided at the center of the side.

As shown in FIGS. 5 and 7, the floating tool 7 has a hollow-shaped air pressure holding area 7a having an open bottom surface facing the equipment floor F, and is formed inside the annular bank 7b. And a compressed air supply port 7d in a suitable place such as the ceiling surface 7c.
Is opened to guide the compressed air supplied from the compressed air supply port 7d to the air pressure holding area 7a. The compressed air supply port 7d of each floating tool 7 is connected to a pressure-resistant rubber pipe 8 (see FIG. 6) extending to the outside via a pipe and an on-off valve (not shown) provided in the apparatus main body 32. I have. The pressure-resistant rubber tube 8 has its tip joined to a compressor (not shown) for supplying clean compressed air free of moisture and dust. As shown in FIG. 5, when clean compressed air is supplied to the air pressure holding areas 7a of the respective floating tools 7, the coating apparatus 31 uses the air pressure generated between the air pressure holding areas 7a and the equipment floor F to release the floor. Floats on surface F.

The coating device 31 includes a rear end 32 of the device main body 32.
A push handle 15 is attached to b, so that it can be pushed and pulled in the direction of arrow E which is the left and right direction. The restraining wheel 16 disposed at the center of the bottom side of the apparatus main body 32 for restraining the moving direction in one direction includes a wheel 17 rotatably supported so as to be guided in an arrow E direction, and a wheel 17. Pressing means 18 having a built-in biasing tool such as a pressing spring for pressing downward
And

In the coating device 31, the wheel 17 of the restraining wheel 16 is pressed against the floor surface F when ascending, so that when the pushing handle 15 is pushed and pulled, it is moved only in the direction of the arrow E without skidding. Can be. When it is desired to change the movement direction when the coating device 31 floats, the push handle 15 may be pushed and pulled in a circumferential direction around the wheel 17 of the restraining wheel 16. This direction change can be easily performed with a light force because the contact between the wheel 17 and the floor surface F is a line or point contact.

The restraining wheel 16 rotatably supports a bracket that supports the wheel 17 and includes a remote control device for remotely controlling the rotation angle of the bracket, thereby enabling the coating device 31 to move in the moving direction. May be configured to be changed. Further, the restraining wheel 16 guides a bracket that supports the wheel 17 so as to be able to move up and down, and has a remote control device that remotely controls the raising and lowering of the bracket, thereby cutting off the contact of the wheel 17 with the equipment floor F. In some cases, the moving direction of the transfer device 1 can be freely selected.

The procedure for replacing the coating device 31 is performed as follows. First, the operator releases the connection between the driving device 25 installed in the coating equipment 20 and the coating apparatus 31, and releases and prepares a locking device (not shown) for fixing the coating apparatus 31. . Next, the worker floats the coating device 31 with the compressed air supplied to the four floating tools 7,
Move to the desired position. At this time, the coating device 31 generates air pressure between the floating tools 7, 7,... And the floor surface F by clean compressed air supplied through the pressure-resistant rubber tube 8, and floats on the equipment floor surface F. I do. The floating coating device 31
Since there is no frictional resistance with the floor F, the guide wheel 15 is moved in the direction of the arrow E by the restraining wheel 16 with a very small operation force on the pushing handle 15.

When the removal of the coating apparatus 31 is completed, the operator holds the other coating apparatus 31 to be replaced in a state where the other coating apparatus 31 is floated, and the front and rear devices 23 (for example, an unwinding apparatus) of the coating equipment 20.
It is moved to the coating device installation area A formed between the front and rear devices 24 (for example, a drying device). Thereafter, the supply of the compressed air is stopped and the compressed air is lowered onto the floor F. Next, the worker fixes the lowered coating device 31 with the locking device and joins the coating device 31 and the drive device 25 to complete the replacement operation.

[0012]

The coating apparatus 3
1 is a horizontal axis C such as a coating roll and a coating equipment 2
It is necessary to stop accurately at a predetermined position in the coating device installation area A so that the axis in the left-right direction of a guide roll (not shown) or the like arranged at 0 is parallel. The axis C of the coating device 31 and the axis of the coating equipment 20 are made parallel so that the web passes through the coating device 31 without meandering.

Incidentally, the conventional coating equipment 20 does not include a device for accurately stopping the coating device 31 at a predetermined position in the coating device installation region A. , It is necessary to correct the stop position by repeating rising and lowering by the floating tools 7, 7,.... However, since this correction operation requires a lot of time, the operation efficiency of the conventional coating equipment 20 is reduced.
