  • Patent number: 11968786
    Abstract: A component replenishment management system includes an emergency device extraction unit, an emergency time setting unit, a replenishable device identification unit, and a replenishment target extraction unit. The emergency device extraction unit extracts, as first and second emergency devices, top two component supply devices having highest degree of emergency for performing the component replenishment work. The emergency time setting unit sets an emergency time zone from a first emergency time for the component replenishment work for the first emergency device to a second emergency time for the component replenishment work for the second emergency device. The replenishable device identification unit identifies, as a replenishable device, a component supply device that can be replenished with a component storage member.

  • Publication number: 20240124234
    Abstract: In a component warehousing support apparatus, the stock quantity which is the number of target components to be warehoused, which are actually stored in each of component storages, is acquired for each of the plurality of component storages. Then, the warehousing destination candidate information indicating a candidate of the warehousing destination of the target component among the plurality of component storages is calculated on the basis of the stock quantity of the target component in each of the plurality of the component storages. Therefore, a candidate of the warehousing destination in accordance with the stock quantity of the target component in each component storage can be confirmed with reference to the warehousing destination candidate information. As a result, it becomes possible to easily determine an appropriate component storage as the warehousing destination of the component from among the plurality of component storages.

  • Publication number: 20240015942
    Abstract: The component storehouse storing the tray in the tray storage rack (tray storage part) is notified of the magazine preparation command indicating the component to be held in the slot of the magazine. In response to this, the component storehouse includes the working robot (work implementation part) that conducts a predetermined work including the tray extraction work, the tray placement work, and the pallet insertion work. The working robot prepares the magazine where the component indicated by the magazine preparation command is held in the slot. In this way, it becomes possible to prepare the magazine automatically where the pallet is inserted in the slot with the tray housing the component placed on the pallet, thereby allowing manpower-saving in component replenishment.

  • Patent number: 11778797
    Abstract: In a component replenishment management system, a component supply monitoring unit estimates replenishable time, which represents time until component replenishment work becomes possible, for each of component supply devices. A work determination unit determines whether or not the component replenishment work can be actually performed at a timing at which replenishment component type information is acquired by an external input and output unit. In a case where the work determination unit determines that the component replenishment work cannot be performed, a work guidance unit generates performing process guidance information. The performing process guidance information is information for guiding a performing process based on the replenishable time of the component replenishment work.
