Title: Control method for continuous quantitative segmenting of raw material
Inventor: ISHIKAWA TOSHIYUKI
IPC: G01G13/00
Filed: 1987-05-06
Abstract: PURPOSE:To perform feed control continuously when a raw material is charged in a weighing hopper by arranging and controlling two quantitative segmenting controllers. CONSTITUTION:When a 1st quantitative segmenting controller 10a starts feed control first, the setting signal WS of a target segmenting quantity setter 21 is supplied to a weighing regulator 12a. A feeder 5a is so controlled that this signal WS equals the differential value of a signal WA from a load detector 4a. Further, when the raw material level of the weighing hopper reaches a specific lower limit, the setting signal WD1 of a segmenting quantity reducer 22a is supplied to the regulator 12a with the signal until zero and the segmenting quantity decreases momentarily. The output signal of a subtracting circuit 23a is supplied to a weighing regulator 12b with a signal indicating the level reaches the lower limit of the weighing hopper and a 2nd quantitative segmenting controller 10 starts segmenting control. Then the sum of segmenting quantities WA and WB from the controllers 10a and 10b is so controlled as to equal to the sum of the signals WD1 and WM1, and the signal WS is maintained eventually. Those two kinds of control are performed alternately to perform the quanti tative segmenting of the raw material continuously.

A mold having a cylindrical hollow part the inner diameter RC of which is larger than RA and the face LO of which is longer than LB is used. After the core shaft 1 is inserted in silicone sponge 2 which is extruded and cured continuously so as to have a nearly uniform thickness, both the ends of the sponge 2 is cut off so as to make the face of the sponge 2 equal to LO and the outer peripheral surface of the sponge is ground so as to make the outer diameter of the sponge equal to RB. After the resultant sponge roller is fixed in the cylindrical hollow part of the mold main body 4, is which the core shaft 1 stands on its end, low-temperature curing silicone rubber is poured in the hollow part of the mold main body so as to be cured by heating. After the removal from the mold, the outer peripheral surface of the surface rubber layer 3 is ground. Thus, the loss at the outer layer portion is reduced and the quality of the obtained rubber roller is stabilized.
