Conventionally, a component supply device is known. A component supply device is disclosed in Japanese Patent No. 4368612, for example.

Japanese Patent No. 4368612 discloses a component supply device including tray plates on which trays, on which components have been placed, are arranged, a tray magazine capable of holding a plurality of tray plates, and a tray plate placement portion on which a tray plate that has run out of components is placed. In this component supply device, tray plates that have run out of components are pulled out one by one of the tray magazine and are placed on the tray plate placement portion, and an operator replenishes the trays with components at the tray plate placement portion.

SUMMARY

In the component supply device disclosed in Japanese Patent No. 4368612, the tray plates that have run out of components are pulled out one by one of the tray magazine and are placed on the tray plate placement portion, and at the tray plate placement portion, the operator replenishes the trays with components. Therefore, the operator needs to perform a replenishment operation each time the tray plate runs out of components. Furthermore, when all the components of the trays of the tray magazine are run out, it is necessary to interrupt the component mounting operation until the operator completes component replenishment, and thus the component mounting operation may be disadvantageously interrupted for a long time. Therefore, there are problems that the work burden on the operator performing a component replenishment operation is increased, and it is difficult to significantly reduce or prevent prolonged interruption of the component mounting operation.

Therefore, the present disclosure provides a component supply device and a component mounting device, both of which are capable of significantly reducing or preventing an increase in the work burden on an operator performing a component replenishment operation and significantly reducing or preventing prolonged interruption of the component mounting operation.
