  • Publication number: 20220413470
    Abstract: A production management system is capable of detecting an abnormal tendency in a production line device forming a production line and finding out a trouble of the production line device at an early stage. The production management system includes a weighing device and a packaging device which are production line devices, an inspection device, and a host computer. The production line devices, the inspection device, and the host computer are configured to communicate with each other via a network. The inspection device transmits inspection result information in the own device to the host computer. The weighing device and the packaging device transmit processing result information in the own devices to the host computer. The host computer detects the abnormal tendency of the production line device based on the inspection result information and/or the processing result information and outputs an alarm.

  • Publication number: 20220375005
    Abstract: There is provided a production management system capable of grasping a production line device that has caused a decrease in production efficiency and notifying an operator that the production efficiency of the entirety of the production line has decreased. A production line device including a weighing device, a packaging device, an inspection device, and a caser, and a host computer are configured to communicate via a network. In a case where a predetermined event has occurred in each of the production line devices, the production line device transmits event data indicating that the event has occurred, to the host computer. In a case where the host computer determines that production efficiency has decreased, based on the received event data, the host computer specifies the production line device that has caused the decrease in the production efficiency and outputs an alarm indicating that the production efficiency has decreased.

  • Publication number: 20180298857
    Abstract: An impeller for a fuel pump is molded by a molding material containing a phenolic resin and an inorganic filler. A content at a minimum spin-spin relaxation time is 70% or higher with respect to a whole when approximating a free induction decay curve, which is obtained by Solid Echo Method in a pulse NMR measurement at 90° C., with a sum of relaxation curves of three components. The content at the minimum spin-spin relaxation time corresponds to a content of a portion of the phenolic resin, which forms the impeller for the fuel pump, where a cross-linking reaction is caused. A swelling amount of the impeller due to a liquid containing a fuel and water decreases as a crosslink density of the phenolic resin increases. The swelling amount of the impeller in the present disclosure is smaller than the swelling amount of an impeller molded by PPS resin.
