<Operation in electrical component mounting system>
In each of the mounting machines 4, when the mounting work on the line I {for example, the work JOB (a)} on the mounting machine 4A is completed, the mounting work {JOB (1)} on the line II is executed, but the mounting work JOB ( Preparations for switching from a) to mounting work JOB (1), so-called setup change, are performed when necessary. In the setup change, it is troublesome for the operator to replace or mount the nozzle N mounted on the tray T, and it takes a long time. In addition, in the case of manual work, an erroneous nozzle may be placed.
Therefore, in this embodiment, the operator may set the tray T to be used in the next mounting operation in the tray holding portions 168 and 170, and the nozzle management machine 6 automatically transfers the nozzle N. The tray information TD (i) of the tray T set in the tray holding units 168 and 170 is acquired, and based on the tray information TD (i) and the production plan JOB information stored in the storage unit 262 of the host PC 8. The nozzle information {ND (i), NP (i)} regarding the nozzle N to be placed on the tray T represented by the tray information TD (i) is determined, and the nozzle information {ND (i), NP (i) } The transfer of the nozzle N is performed based on. When the nozzles are previously mounted on the trays T mounted on the tray holding portions 168 and 170, the unnecessary nozzles are removed and transferred to the pallet P, and the necessary nozzles are transferred from the pallet P. The nozzles are replaced. When the nozzle N is not placed on the tray T set in the tray holding portions 168 and 170, the nozzle N is transferred from the pallet P to the tray T based on the nozzle information {ND (i), NP (i)}. Is relocated to a predetermined position. Hereinafter, these are referred to as nozzle transfer.

In the nozzle management machine 6, the nozzle transfer program shown in the flowchart of FIG. 12 is executed.
In step 21 (hereinafter abbreviated as S21; the same applies to other steps), it is determined whether or not the tray T is set in the tray holding portions 168 and 170. For example, it is possible to determine whether or not the tray T has been set based on the presence or absence of input via the operator's input device 254 (for example, a nozzle transfer instruction). In S22, the transfer head 200 is moved, the tray T is imaged by the camera 222, and the tray information TD is acquired {for example, the acquired tray information is TD *}. In S23, the JOB list shown in FIG. 11B transmitted from the host PC 8 is read. For example, the nozzle management machine 6 can transmit list request information and nozzle transfer instruction information to the host PC 8, and the JOB list can be supplied accordingly.

In S24, one of the JOBs whose nozzle transfer end information is "not yet" is selected from the JOB list, and the JOB name (for example, JOB (2)) is transmitted to the host PC 8. For the JOB name {JOB (2)}, it is assumed that the JOB counter i is specified by 2 (i = 2) in this embodiment. The host PC 8 selects the tray information TD (2) included in the JOB (2) information whose JOB name is JOB (2) from the production plan JOB information shown in FIG. 11 (a). The tray information TD (2) corresponding to 2) may be referred to}, and the information is transmitted to the nozzle management machine 6. In S25 and 26, in the nozzle management machine 6, the received tray information TD (2) and the tray information TD * acquired in S22 are compared, and it is determined whether or not they match. If they do not match, the JOB counter i is incremented by 1 in S27, returned to S24, and JOB (3) is selected. By executing S24 to 26, it is determined whether or not the tray information TD (3) corresponding to JOB (3) and TD * match. Hereinafter, S24 to 27 are repeatedly executed until the TD * and the tray information TD (i) transmitted from the host PC 8 match.

Then, when TD (i) {for example, i = x} and TD * match, the determination in S26 becomes YES, and the JOB name {JOB (x)} is transmitted from the nozzle management machine 6 to the host PC 8. .. The host PC 8 selects and transmits nozzle transfer end information (completed or unfinished) corresponding to JOB (x). In the nozzle management machine 6, in S28, it is determined whether or not the transmitted nozzle transfer end information is "not yet", and if it is "not yet", the determination is YES and S29 is executed. If it is "finished", the JOB counter is incremented by 1 in S27 and returned to S24. Hereinafter, S24 to 28 are repeatedly executed, and JOB information that includes the same tray information TD (i) as TD * and whose nozzle transfer end information is “not yet” is searched.
If the nozzle transfer end information corresponding to JOB (x) is "not yet", the determination in S28 becomes YES, and the JOB (x) name is transmitted from the nozzle management machine 6 to the host PC 8. The host PC 8 transmits nozzle information {ND (i), NP (i)}, etc. corresponding to JOB (x). In the nozzle management machine 6, nozzle information {ND (i), NP (i)} and the like are read in S29, and in S30, the presence or absence of inventory of the nozzle N is determined based on the nozzle management information shown in FIG. Nozzle information {ND (i), NP (i)} Nozzle type information It is determined whether or not the number of nozzles N of the type represented by ND (x) or the like is accommodated in the pallet accommodating device 74 in excess of the required number. It is. When the nozzle N is out of stock, the JOB counter is incremented by 1 in S27, S24 to 30 are repeatedly executed, the tray T of the same type as the TD * is used, and the nozzle transfer end information is "not yet". JOB information that is present and has nozzle inventory is searched.
