Level for roll horizontal adjustment (Roll axis adjustment level)
Rolls are often used as parallel rolls in manufacturing lines for paper, vinyl sheets, steel strips, etc. However, if the horizontal accuracy of the roll axis is poor, problems such as transport jams can occur. In other words, paper, vinyl sheets, and steel strips flow to the left or right, and rolled products are not wound up cleanly, resulting in a loss of product quality. In some cases, the product must be discarded. To prevent this, this product is designed to be placed on a flat roll for leveling.
Features
01 Used for leveling horizontal rolls
02 Applicable to rolls with diameters from φ40 to φ200
03 Special jig (*) enables stable measurement of horizontal roll angle
※ See supplementary explanation.
04 Angle measurement range: 2 axis type: ±0.3 degrees, 1 axis type;±1.0 degree Accuracy(repeatability)
2 axis;±0.001 degree(range ±0.3deg)
1 axis;±0.005 degree(range ±1.0deg)
Supplementary explanation
The following is a description of “roll axis misalignment” in conveyor rollers of printing equipment.
Stable measurement of the roll axis as indicated in Feature0 3 and installation of a digital level are shown below.
The roll axis adjustment level consists of the sensor used in the digital level held in the center of a dedicated jig. Two SUS cylinders are placed on the bottom of the dedicated jig, and when placed on the top surface of the roll to be measured as shown in the figure above, the roll axis and the tangential cylindrical axis of the digital level jig are aligned parallel, enabling stable horizontal angle measurement of the roll axis.
