Title: Method for controlling start of cascade
Inventor: SHIBATA NAGAHIKO
IPC: G05B13/02
Filed: 1982-05-21
Abstract: PURPOSE:To minimize the quantity of nonstandardized products by controlling many cascades collectively in consideration of mutual relation. CONSTITUTION:A signal from pressure gauge 17j(j=1,2...N) for material supplying stage feed header of each cascade 11 and a signal from a flowmeter 18j for material supplying pipe are respectively inputted to a valve opening controller 25, which processes these signals and output a valve operating signal to each control valve 15j. Although it is ideal to control flow rate for material supply at the operation of each cascade, the supplying performance of a material supplying device 16 is generally designed so as to have almost rated one. However, it is necessary to supply the quantity of several times the rated one to each cascade, so that it is impossible to start the whole cascades 11l-11N simultaneously. Therefore, some cascades are simultaneously started, but other cascades are stopped and waited. When the flow rate to supply the material to the started cascades is reduced, the remaining cascades are started successively.

The speed command set according to the signal is continuously emitted from said generator. The motor 39 runs according to the speed command value. For example, the motor runs at a low speed at the start and the speed is gradually increased to the high speed. The speed is gradually decreased in the position where a moving die 6 moves near to an upper die 5. Selection switches 55 and 58 are changed over to change over the control system to the 2nd speed control system at the point of the time when the speed coincides with the max. speed of the motor 44. The speed is further decreased and a material to be molded is molded between the upper die and the moving die 6. The pressing power of the die 6 is released when backward rotating power is thereafter exerted to a screw shaft 36 by the motor 44. Both dies 5 and 6 are detached when the shaft is rotated backward by the motor 39.
