Title: Method for judging plan completion time in multiple orifice continuous extrusion
Inventor: TOKUHIRO NAOMICHI
IPC: B29C48/92
Filed: 1989-12-28
Abstract: PURPOSE:To make it possible to judge the plan completion time in multiple orifice continuous extrusion by a method wherein the numbers of extruded products per unit time is calculated for respective continuous extrusions on the basis of respective cutting intervals of a large number of extrudates and, on the basis of the data obtained by said calculation, the expected time of the achievement of designed number of extruded products is calculated. CONSTITUTION:Limit switches Li and cutters Ci are arranged to the respective extrudates 3... from an extruder. When the extrudate 3, which is formed by and extruded through a mold 2, strikes the limit switch Li, the cutter Ci is put into actuation so as to produce one extruded product 3. By means of relays Si, which are attached to the respective cutters Ci, cut signal is inputted when the cutter Ci is put into actuation. When any one of cut signals is inputted, the signal is inputted in a microcomputer M so as to start the timer of the microcomputer. The timer is stopped by inputting next cut signal so as to obtain the cutting time interval in order to calculate the number of extruded products per unit time. Accordingly, by subtracting the number of actually extruded products from the number of designed extruded products, the rest number of products to be produced further is ascertained.
