Title: Control device for measuring distance of transfer line
Inventor: HOTTA HIROYOSHI
IPC: B21B39/08
Filed: 1989-09-12
Abstract: PURPOSE:To eliminate an error due to the change of the roll diameter of transfer rolls by calculating the distance of material in the part of transfer roll by determining the contact angle between the transfer roll and the material due to the diameter of the transfer rolls. CONSTITUTION:First, the distance L between the center points of an upper roll and lower roll is obtd. to determine the distance l3 between the contact points of material between the upper roll and the lower roll 1, 1 of the transfer roll. The distance l3 between the contact points of material between the upper roll and the lower roll is obtd. by the use of that distance L. Next, the distance l2 of the contact part of material with the lower roll of the transfer roll and the distance l4 of the contact part of material with the upper roll are determined. However, because the roll diameters of rolls of the upper roll 1 and the lower roll 1 have the same value, they are l2=l4. To determine l2=l4, l2=l4 is determined by determining theta3. By this way, l2, l3, and l4 are determined. The distance from a detecting sensor 3 for the position of material to the contact point 5 of material on the outlet of the transfer roll and the distance from the sensor 3 to the position of a fixed machine 2 are determined by adding fixed values of l1 and l5, and the error due to the change of the roll diameter of the transfer roll 1 can be eliminated.
