IPC: B29C45/76
Filed: 1989-02-14
Abstract: PURPOSE:To detect the time of utilization limit of a plasticizing equipment in the future by measuring plasticizing time for plasticizing constant amount of material in an arbitrary time from start up of the plasticizing equipment and calculating the time necessary until the measured plasticizing time reaches the preset plasticizing time. CONSTITUTION:When the relational expression of both plasticizing time T for plasticizing constant amount of material and elapsed time (t) from start up of a plasticizing equipment is shown as T=f(t), plasticizing time T1 in the arbitrary time t1 from start up of the plasticizing equipment is formularized in T1=f(t1). When plasticizing time more than this is necessitated and the limit value of time for causing an obstacle in production is T2, the time reaching T2 from the plasticizing time T1 may be calculated. In other words, T1 and t1 are measured and t2 may be calculated from T2=f(t2). When t2 is calculated, it is output as an electric signal and plasticizing time can be indicated as date and time. Further when the plasticizing time reaches the prescribed time a little before the limit value and an alarm is issued, stopping of the plasticizing equipment can be incorporated in a production planning.
