In general, for example, in the case of manufacturing printing equipment composed of several rolls as in Korean Patent No. 0873847, the setup accuracy of the roll greatly affects the quality of the printed product. In particular, parallelism between rolls is an important technology for improving the printing precision in the field of printing electronics, and high technology demand is expected in the future.

On the other hand, in the film printing process using a roll, when the parallelism of the rolls is not coincident with each other, there arises a problem that a film or the like passing through the rolls can not be produced in a meandering or folded film uniformly.

In order to solve the parallelism between rolls, a tape measure or the like has been used. Such a conventional roll parallelism measuring device has a problem that it is difficult to accurately and accurately fix the tape measure during the measurement operation. Also, measurement equipment using laser has been attempted, but it is troublesome to use it as expensive equipment.

In addition, in the conventional roll parallelism measuring apparatus, it is difficult to replace the gauge when the gauge for measuring the parallelism between the rolls fails.

A coupling hole having a thread is formed so that the bolt 34 can be fastened to the coupling part 124 and the roll seating part 121. The bolt 34 is inserted into the coupling part 124 and the roll seating part 121 So that the engaging portion 124 and the roll seat 121 can be coupled and fixed to each other.

In order to form a 'V' groove that is opened toward the shaft 22 of the second roll, the seating groove 122 is formed in the second housing 120 As shown in Fig. The shaft of the second roll is inserted into the groove of the V groove on both sides of the seating groove portion 122 so that the shaft can be simultaneously contacted with the V groove of the second roll through the second dial indicator, (22) is measured and displayed.

The first dial indicator 13 and the second dial indicator 14 are connected to the shaft 21 of the first roll and the shaft 22 of the second roll, (131, 141), respectively. The through-holes for the measurement rods 131 and 141 are respectively formed in the roll seating belts 111 and 121, respectively. That is, the measurement rods 131 and 141 of the first dial indicator 13 and the second dial indicator 14 are inserted into the through holes formed in the roll seating portions 111 and 121 of the first housing 110 and the second housing 120 The first dial indicator 13 and the second dial indicator 14 are respectively installed in the first housing 110 and the second housing 120 such that the first dial indicator 13 and the second dial indicator 14 are passed through the first dial indicator 13 and the second housing 120, 2 dial indicator 14 are connected to the shaft 21 of the first roll and the second roll 21 which are fixed by the roll seating belts 111 and 121, the drop prevention portion 112 and the seating groove portion 122, Respectively, to measure the gap.

The length varying parts 132 and 142 include spindle guides 133 and 143 and holders 134 and 144 that can vary the protruding lengths of the measurement rods 131 and 141 by rotating relative to the spindle guides 133 and 143 .

Hereinafter, a method of operating the apparatus for measuring roll parallelism using the dial indicator according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 4, when it is necessary to measure a plurality of roll parallelograms using the roll parallelism measuring apparatus 1 using the dial indicator, first, the shaft 22 of the second roll is rotated in the second The second dial indicator 14 is inserted into the groove of the V groove formed on the outer side of the housing 120 so that the shaft 22 of the second roll can be in contact with the V groove, The gap between the second roll 22 and the shaft 22 can be measured and displayed.

At this time, it is possible to confirm whether or not the shaft 22 of the second roll is exactly fixed to the roll seat 121 of the second housing 120 through the second dial indicator 14. For example, when the shaft 22 of the second roll is correctly fixed to the roll seat 121 of the second housing 120, a scale indicated by the second dial indicator 23 is set as a seating reference point The shaft 22 of the second roll is not fixed to the roll seat 121 of the second housing 120 when the scale indicated by the second dial indicator 23 is deviated from the seating reference point The shaft 22 of the second roll is moved to the second housing 120 when the scale indicated by the second dial indicator 23 reaches the seating reference point by changing the posture of the roll parallelism measuring device 1, It can be judged that the roll rests 121 are correctly fixed.

Next, in a state where the roll seat 111 of the first housing 110 is located adjacent to the shaft 21 of the first roll among the plurality of rolls, So that the roll parallelism measuring apparatus 1 is prevented from dropping or being separated from the shaft 21 of the first roll.

At this time, the roll parallelism measuring device 1 is positioned at a different point on the shaft 21 of the first roll and the shaft 22 of the second roll, with the scale indicated by the first dial indicator 13 being a parallel reference point And the roll parallelism can be measured based on whether or not the scale indicated by the first dial indicator 13 deviates from the parallel reference point. For example, after the roll parallelism measuring apparatus 1 is moved to be located at a different point on the shaft 21 of the first roll and the shaft 22 of the second roll, the first dial indicator 13 If the scale is deviated from the parallel reference point, it can be determined that the plurality of rolls are not positioned parallel to each other. Conversely, after the roll parallelism measuring device 1 is moved to the other position on the shaft 21 of the first roll and the shaft 22 of the second roll, the scale indicated by the first dial indicator 13 If it is still located at the parallel reference point, it can be determined that the plurality of rolls are positioned parallel to each other.

That is, according to the roll parallelism measuring apparatus 1, the change in the distance between the plurality of points on the shaft 21 of the first roll and the shaft 22 of the second roll is measured to measure the plurality of roll parallelism You can.

Therefore, according to the present invention, there is an advantage that the roll parallelism measurement can be performed more easily and accurately. The present invention has the advantage that the roll parallelism measurement can be performed at a lower cost and the repairing and replacing operation of the gauge can be made simpler.

It will be apparent to those skilled in the art that many other modifications and variations are possible in light of the above teachings and the scope of the present invention should be construed on the basis of the appended claims will be.
