By reading the identifier 6d, the mounting device 1 and the nozzle management device 31 can acquire the nozzle management information associated with the nozzle ID obtained from the identifier 6d from the host computer 19.

The nozzle status information includes information on the number of shots of parts sucked by the mounting device 1, maintenance necessity information, inspection necessity information, usability information, and maintenance date and time (date and time when inspection or cleaning was performed). The number of shots is the number of times that the nozzle 6 executes the operation of holding the component in the mounting device 1. The number of shots includes the total number of lifetime shots that have been adsorbed from the new state and the number of shots after maintenance. The nozzle state information is updated by an accompanying maintenance device (not shown), and the updated result information is transmitted to the host computer 19.

The maintenance necessity information is information in which the information processing unit 19a determines whether or not maintenance is required for each nozzle 6 based on predetermined determination criteria such as the number of shots and the usage time. Here, maintenance includes at least cleaning of the nozzle 6. The inspection necessity information is information in which the information processing unit 19a determines whether or not each nozzle 6 needs to be inspected based on predetermined determination criteria such as the number of shots and the usage time. Here, the nozzle inspection is, for example, an inspection of the air flow rate flowing through the nozzle, the shape of the nozzle tip, and the like. The usability information is a judgment result of usability at the time of completion inspection after maintenance and nozzle inspection. The maintenance necessity information and the inspection necessity information are recorded based on the determination result of the information processing unit 19a as described above, but are removed from the mounting device 1 and stored in the nozzle management device 31 regardless of the number of shots and the usage time. The maintenance necessity information of the nozzle 6 stored in the returned changer 9 may be set as "necessary", and the inspection necessity information may be set as "necessary". That is, the nozzle 6 housed in the changer 9 returned to the nozzle management device 31 may always be maintained and inspected.

The nozzle location information is information that can specify the storage position of the nozzle 6. When the nozzle 6 is stored in the nozzle pallet 39, the ID information of the stored nozzle pallet 39 and the information regarding the storage position are included.

The location of the changer 9 and the nozzle pallet 39 can be controlled from the amount of movement of the transfer head 43, and the storage location in the changer 9 and the nozzle pallet 39 can be specified.

Further, the information processing unit 19a of the host computer 19 stores the nozzle ID in the storage unit 19b in association with the changer management information. The changer management information includes a changer ID and changer location information. The changer ID is attached to each changer 9 as an identifier 9e. The identifier 9e is attached as, for example, a two-dimensional barcode, a QR code (registered trademark), or an RFID tag. The changer location information is information that can specify the storage location of the nozzle 6 in the changer pallet 35. Further, it is managed so that the position of the changer in the mounting device 1 and the carriage 21 during the external setup can be specified as well as in the nozzle management device 31.

The control unit 42 of the nozzle management device 31 includes an image recognition unit 42a, a mechanism control unit 42b, a transfer control unit 42c, and a storage unit 42d. The control unit 42 includes, for example, an arithmetic unit such as a processor and an FPGA as an image recognition unit 42a, a mechanism control unit 42b, and a transfer control unit 42c. Further, a storage device composed of at least one such as a memory, a hard disk, and an SSD is included as the storage unit 42d, and the processing programs of the image recognition unit 42a, the mechanism control unit 42b, and the transfer control unit 42c are stored. The control unit 42 is connected to the host computer 19 by wire or wireless communication.

The nozzle management device 31 acquires nozzle management information regarding the nozzle 6 to be stored from the host computer 19 and stores it in the storage unit 42d. The transfer control unit 42c instructs the transfer unit 41 to move the nozzle 6 on the nozzle pallet 39 based on the nozzle management information.

For example, the transfer control unit 42c instructs the transfer unit 41 to store another nozzle 6 of the same type in the nozzle pallet 39 near or adjacent to a nozzle 6 of a certain type. As a result, in the nozzle pallet 39, the nozzles 6 of the same type are collectively collected at a location close to or adjacent to each other, so that the time required to convey the nozzles 6 of the same type to the work stage 37 can be shortened. For example, a nozzle pallet 39 dedicated to a specific nozzle may be provided, and the nozzles 6 may be housed in the nozzle pallet 39 for each type. Further, one nozzle pallet may be divided into a plurality of sections and stored in the corresponding sections according to the type of the nozzle 6. For example, the large nozzle 6 may be stored in the region Na on the work stage 37 side in the nozzle pallet 39, and the small nozzle 6 may be stored in the region Nf on the nozzle magazine 55 side in the nozzle pallet 39.

Further, the nozzle pallet 39 may be divided according to the state of the nozzle 6, or the storage section of the nozzle pallet 39 may be divided. For example, a nozzle pallet 39 dedicated to the unusable nozzle may be prepared, or a part of the nozzle pallet 39 may be set as a storage compartment for the unusable nozzle 6. For example, the unusable nozzle 6 may be stored in the area Nf on the nozzle magazine 55 side away from the work stage in the nozzle pallet 39.
