Apparatus and method for automatic supply of lubricants.

摘要

PURPOSE:To grease automatically a mechanism section driven by a servo motor securely in the appropriate timing by issuing a driving signal of a greasing device when the error voltage is beyond the grease starting voltage. CONSTITUTION:When greasing decision treatment is instructed during the operation of an injection molding machine, a CPU 52 for PMC of CNC 50 displays a display for measuring greasing on a CRT display treatment of CRT/MD 157. The grease staring voltage and the specified position of a movable platen 12 are read from a common RAM 56 and stored in RAM 53 tentatively, and when the present position of the movable platen 12 reaches the specified position, CPU 52 for PMC reads the error voltage at that time and compares the error voltage with the grease starting voltage. When the error voltage is beyond the grease starting voltage, a driving signal of a greasing device 30 is output from an output circuit 60 to a driving section 31. Automatic greasing can be carried out properly in proper timing by said processing.
