DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a calender roll profile measuring device.

[0002]

2. Description of the Related Art In a rubber calender or the like, since the flatness of the surface of a roll greatly affects the quality of a product, it is necessary to appropriately polish the roll in accordance with a change in profile (wear). Conventionally, in order to obtain the management data, a profile is obtained by measuring the diameter of a roll with a roll caliper equipped with a micrometer.

[0003]

However, the measurement using the roll calipers requires considerable skill and has a problem that the reliability as management data is low because the measurement varies depending on the measurer.

For example, in the case of a four-roll calender, in order to measure the third roll profile, a gap with the second roll must be opened so that a caliper can be inserted. Had become.

On the other hand, in the field of rolling mills, a technique for accurately detecting the profile of a work roll has been proposed (for example, JP-A-3-186712).
This device was complex and large, and was difficult to use for calendars.

In view of the above circumstances, the present invention has been devised in order to provide a calender roll profile measuring device which is simple, easy to operate, and capable of accurate profile measurement.

As shown in FIGS. 3 and 4, one side of the slide table 7 is appropriately grooved so as to fit into the guide rail 8, and a mounting member is provided on the opposite side. A distance detector 12 is provided to support the distance detector 6 so that its detection terminal appropriately faces the roller 3. The mounting member 12 can adjust the distance between the distance detector 6 and the roller 3 to, for example, about 1.0 mm by a screw.
The guide rail 8 is formed to be sufficiently longer than the rolls 1... 4, and is attached to a guide frame 13 having substantially the same length as the rolls along the longitudinal direction. The guide frame 13 includes two guide rollers 14 provided at both ends in the longitudinal direction, and a belt 15 attached to the slide table 7 at both ends and wound around the guide rollers 14.
And a motor 19 for rotating a drum 17 for driving the belt 15. One end of a cable 29 is attached to the slide table 7, and the other end of the cable 29 is wound around the guide roller 14 and connected to the position detector roller 16. That is, these constitute a moving means 9 for appropriately moving the slide table 7 back and forth via the belt 15.

The holding means 10 is, as shown in FIGS. 1 and 2, a guide frame 1 for supporting the guide rail 8.
3 , two rail holding members 30 attached to both end sides
And two arms 18 for appropriately fixing the respective rail holding members 30 to the roll 3. Each of the rail holding member 30, the roll 3 side from the mounting portion 19 of the guide frame 13 has two legs 20 extending like angle to each other at right angles, these
The leg 20 is engageable with the roll 3 so as to sandwich the same.

Support means are configured. The arm base ends 27 are connected to each other by a horizontal rod 28, are formed as handles for swinging and sliding operations, and serve as counterweights on the distal end side.

The arithmetic processing unit 11 is connected to the moving means 9 and the distance detector 6, and calculates the axis of the roll surface based on the input cable winding amount (extending amount) of the position detector roller 16 and the detected distance value. Seeking a profile along the direction,
It is recorded as management data. Then, the wear amount is calculated by comparing the profile value at the time of new installation with the measured profile value, and if the wear amount requires polishing, it can be displayed to alert the administrator.

Next, the operation of this embodiment will be described.

When obtaining a profile to grasp the abrasion state of the rolls 1 to 4, the supply of hot water for heating the rolls 1 to 4 is first stopped, and the rolls 1 to 4 are set at a predetermined constant temperature close to room temperature. Keep it. The rail holding member 30 is pressed against, for example, the surface of the third roll 3 by appropriately swinging / sliding the arm 18, and all the legs 20 are sandwiched between the rolls 3 and brought into close contact with the rolls 3. 13 and the guide rail 8 are fixed. As a result, the guide rail 8 becomes parallel to the axis of the roll 3, activates the distance detector 6, and moves the slide table 7 from one end of the roll 3 to the other end by winding and feeding the belt 15. At this time, the slide table 7

The slide table 7 or the distance
The separation detector 6 is moved from one end to the other end of the roll 3 over the entire width.
Can be moved. The distance detection value at this time is input to the arithmetic processing unit 11 together with cable scales, recorded or displayed as management data. When the profile measurement for one roll 3 is completed, the operation moves to another roll, for example, the first roll 1 by the arm operation.

As described above, the slide table 7 on which the distance detector 6 is mounted is moved along the guide rail 8, and the rail 18 is provided with the rail holding member 30 having the leg 20. Since the guide rail 8 is fixed in a state parallel to the roll axis, the measurement can be performed accurately without the individual difference of the measurer only by operating the distance detector 6 and the moving means 9. That is, the reliability of the measurement data is improved. In addition, since the measurement can be performed while the rolls 1... 4 are incorporated in the frame of the calendar 5, it is possible to contribute to an improvement in production efficiency. Furthermore, this measuring device has a simple configuration, is applicable to all kinds of calendars, and is extremely versatile.

In this embodiment, accurate setting of the guide frame 13 and the like on the rolls 1... 4 can be easily performed only by operating the arm 18, and the burden on the operator can be greatly reduced. More specifically, the arm 18 is operated to
