Abstract: A removed article storage box having a box-shaped body into which an article to be removed to an outside of a transport path due to a specific inspection result is input includes weight measuring unit for measuring a weight value of the article input into the box-shaped body and for measuring a first measurement value measured at a preset fixed cycle and a second measurement value measured at a time at which a predetermined time elapses after the removal, input determination unit for determining, based on the first and second measurement values, whether or not the article with the specific inspection result is input into the box-shaped body from the transport path within a predetermined time after the removal, and notification output unit for performing a notification output of a storage state of the article in the box-shaped body according to a determination result of the input determination unit.

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.

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.
