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.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application is a National Stage of International Patent Application No. PCT/JP2020/048759, filed Dec. 25, 2020, the entire contents of which is incorporated herein by reference. BACKGROUND Technical Field The present disclosure relates to a technique of mounting a component on a board, specifically, to a technique of supplying a component housed in a tray placed on a pallet having been pulled out from a slot of a magazine for mounting of the component on a board. Background Art A component mounter that produces a component-mounted board by mounting a component on a board is required to be replenished with a component as appropriate. In this regard, various techniques have been suggested for component replenishment. According to JP2012-134331, for example, a component supply jig is picked from a component supply jig storage shelf and placed on a component supply carriage in response to a command from a production system, and the component supply jig is conveyed using the component supply carriage. By doing so, a component arranged at the component supply jig is replenished to a component mounter. According to JP2018-507558, a carrier for a bin load unit for supplying a component is provided with a display and information about the bin load unit is presented on the display. According to JP2019-218157, a component tray received from an intermediate storage is loaded to a carrier cart and a self-propelled transport machine conveys the carrier cart. SUMMARY In some cases, the component mounter mounts a component housed in a tray (so-called tray component). Such a component mounter extracts a component from a slot of a magazine having a plurality of slots each configured to hold a component therein, and mounts the component on a board. More specifically, a pallet is insertable into and removable from the slot. While the pallet is inserted in the slot with the tray housing the component placed on the pallet, the component is held on the pallet. Therefore, for component replenishment to such a component mounter, it is preferable that a magazine can be prepared automatically where a pallet is inserted in a slot with a tray housing a component to be mounted by the component mounter placed on the pallet, as it leads to reduction in burden on an operator. By contrast, JP2012-134331 does not give particular consideration to a component requiring a tray, a pallet, and a magazine. Furthermore, JP2018-507558 and JP2019-218157 mainly relate to a technique of conveying a component and do not disclose preparation of a magazine such as that described above. The present disclosure has been made in view of the above-described problems, and is intended to provide a technique allowing manpower-saving in component replenishment by automatically preparing a magazine having a slot in which a pallet is inserted with a tray housing a component placed on the pallet. A component storage system according to the disclosure comprises a component storehouse including a tray storage part storing a tray housing a component, and a work implementation part, that holds a pallet on which the tray extracted from the tray storage part is placed, in a slot provided at a magazine; and a controller that controls the component storehouse. The magazine holds the component housed in the tray placed on the pallet in the slot by holding the pallet in the slot, the controller notifies the component storehouse of a magazine preparation command indicating the component to be held in the slot of the magazine, and the work implementation part prepares the magazine where the component indicated by the magazine preparation command is held in the slot. A component storehouse according to the disclosure comprises a tray storage part storing a tray housing a component; and a work implementation part that holds a pallet on which the tray extracted from the tray storage part is placed in a slot provided at a magazine. The magazine holds the component housed in the tray placed on the pallet in the slot by holding the pallet in the slot, and he work implementation part prepares the magazine where the component indicated by a magazine preparation command is held in the slot, the magazine preparation command indicating the component to be held in the slot of the magazine. A magazine preparation method according to the disclosure comprises a step of notifying a magazine preparation command indicating a component to be held in a slot of a magazine; and a step of preparing the magazine at a component storehouse including a tray storage part storing a tray housing the component, and a work implementation part that holds a pallet on which the tray extracted from the tray storage part is placed in the slot provided at the magazine. The magazine is prepared by causing the work implementation part to hold the component indicated by the magazine preparation command in the slot. According to the present disclosure having the above-describe
