Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To provide an operating time analyzer for automatically conducting an analyzing operation of an operating time at a center by measuring and storing the time at each operating state of an injection molding machine. SOLUTION: An operating state of an injection molding machine is detected at each predetermined period Δt (S1 to S6). The detected periods Δ are sequentially added to detected operating state (S7 to S13) thereby to calculate an integrated time of each operating state. The integrated time of each operating state is read by a central managing system, and stored at each operating state for each injection molding machine. A time ratio of occupying each operating state is calculated based on mutual relation of the integrated times stored in the respective operating states. The operating state and ratio of the each operating state are displayed and output at each injection molding machine.

Filed: 1979-10-05
Abstract: PURPOSE: To effectively remove flocs deposited on filtering layer by a method in which prior to back washing, the level of sand layer is measured and the amount of back washing water is regulated until a target sand layer level predetermined is reached.  
     CONSTITUTION: At the time of back washing, the level of sand layer during washing operation is detected by the sand layer level detector 13, and the opening degree of the back washing water flow rate regulating valve 8 is controlled by the controller 14 until the sand layer level during the washing operation reaches a target sand layer level, corresponding to an optimum sand layer expansion rate, in order to regulate the amount of back washing water. Also, since the optimum sand layer expansion rate (target sand layer level) is charged with temperature, the temperature of water is measured by the water temperature measuring meter 15 as needed to correct the temperature of target sand layer level. Thus, optimum washing effect can be attained from the standpoints of keeping the sand layer clean, preventing the loss of sand, and economy of washing water.
