Further, as shown in FIG. 11(b), a JOB list in which JOB names and nozzle transfer end information are associated is called a JOB list.

<Operation in electrical component mounting system>
In each of the mounters 4, when the mounting work on the line I {for example, the work JOB(a) in 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 job JOB(1), so-called changeovers, are made when necessary. It is troublesome for the operator to replace or place the nozzles N placed on the tray T during the changeover, and it takes a long time. In addition, in the case of manual operation, the wrong nozzle may be placed.
Therefore, in this embodiment, the operator only needs to set the tray T to be used in the next mounting operation in the tray holders 168 and 170, and the nozzle N is automatically transferred in the nozzle management machine 6. FIG. 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, Nozzle information {ND(i), NP(i)} relating to nozzle N to be placed on tray T represented by tray information TD(i) is determined, and nozzle information {ND(i), NP(i) }, the transfer of the nozzle N is performed. When nozzles are previously placed on the trays T placed on the tray holders 168 and 170, unnecessary nozzles are removed and transferred to the pallet P, and required nozzles are transferred from the pallet P. Therefore, the nozzles are replaced. When the nozzle N is not placed on the tray T set in the tray holding units 168 and 170, the nozzle N is transferred to a predetermined position. Hereinafter, these will be referred to as nozzle transfers.

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

In S24, one of the JOBs whose nozzle transfer end information is "unfinished" is selected from the JOB list, and the JOB name (for example, JOB(2)) is sent to the host PC8. The JOB name {JOB(2)} is defined with a JOB counter i of 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 control JOB information shown in FIG. 2), which may be referred to as tray information TD(2)}, is transmitted to the nozzle management machine 6. At S25 and S26, the nozzle management device 6 compares the received tray information TD(2) with the tray information TD* acquired at S22, and determines whether or not they match. If they do not match, the JOB counter i is incremented by 1 in S27, the process returns to S24, and JOB(3) is selected. By executing S24 to S26, it is determined whether or not the tray information TD(3) corresponding to JOB(3) matches TD*. Thereafter, S24 to S27 are repeatedly executed until TD* and the tray information TD(i) sent from the host PC 8 match.

Then, if TD(i) {for example, i=x} matches TD*, the determination in S26 becomes YES, and the job name {JOB(x)} is sent from the nozzle management machine 6 to the host PC 8. . The host PC 8 selects and transmits the nozzle transfer end information (completed or not) corresponding to JOB(x). In the nozzle management machine 6, it is determined in S28 whether or not the transmitted nozzle transfer end information is "not yet". If it is "completed", the JOB counter is incremented by 1 in S27, and the process returns to S24. Thereafter, S24 to S28 are repeatedly executed to search for JOB information that includes tray information TD(i) that is the same as TD* and whose nozzle transfer end information is "not completed".
If the nozzle transfer completion information corresponding to JOB(x) is "unfinished", the determination in S28 becomes YES, and the nozzle management machine 6 sends the JOB(x) name to the host PC 8. FIG. The host PC 8 transmits nozzle information {ND(i), NP(i)} etc. corresponding to JOB(x). In the nozzle management machine 6, the nozzle information {ND(i), NP(i)} and the like are read in S29, and the presence or absence of the nozzle N in stock is determined in S30 based on the nozzle management information shown in FIG. It is determined whether or not more than the required number of nozzles N of the type represented by the nozzle type information ND(x) of the nozzle information {ND(i), NP(i)} is stored in the pallet storage device 74. It is. If there is no nozzle N in stock, the JOB counter is incremented by 1 in S27, S24-30 are repeatedly executed, the tray T of the same type as TD* is used, and the nozzle transfer end information is "not yet." JOB information that is available and has nozzle inventory is searched.

If there is nozzle inventory for JOB(x), the determination in S30 becomes YES, and in S31 nozzle N is transferred based on the nozzle information {ND(x), NP(x)}. When the transfer of the nozzle N is completed, the nozzle transfer end information indicating "completed" for the JOB(x) name is transmitted from the nozzle management device 6 to the host PC 8 . In the host PC 8, in the production plan JOB information shown in FIG. 11(a), the nozzle transfer completion information corresponding to JOB(x) is changed from "uncompleted" to "completed" and stored. Mounting machine information corresponding to JOB(x) is also transmitted to the nozzle management machine 6 . In the nozzle management machine 6, the mounter information is received, and in S32, the completion of the nozzle transfer is displayed on the display 252 in association with the job name {JOB(x)} and the mounter 4x. be.

After confirming the display on the display 252, the operator removes the tray T from the tray holders 168 and 170, places it on a cart near the mounter 4x, attaches a card (memo), etc., to the mounter 4x. Therefore, it is possible to easily recognize that the tray T is the one to be loaded. When the mounting work is finished in the mounter 4x, the tray T can be exchanged satisfactorily.
Further, in the above embodiment, the case where one tray T is set in one of the tray holding portions 168 and 170 has been described, but the same is true when the tray T is set in both. For each T, the nozzle transfer program can be executed in order.
Furthermore, in the above embodiment, the JOB(i) information includes one piece of tray information, but it may include a plurality of pieces of tray information. In that case, the nozzle transfer end information is stored for each tray information. The nozzle transfer completion information corresponding to the JOB name in the list is set to "not completed". In S28, the nozzle transfer end information corresponding to the JOB name is obtained from the JOB list, and the nozzle transfer end information corresponding to each tray information is obtained from the production plan JOB information. Nozzle transfer is performed in the same manner as in the embodiment.

Thus, in this embodiment, the operator only needs to set the trays T on the tray holders 168 and 170, and the nozzles N suitable for the set trays T are automatically transferred. As a result, the operator does not need to perform troublesome tasks such as nozzle replacement and placement, and the time required for setup change can be shortened. Also, it is possible to prevent the wrong nozzle from being placed.
Also, the nozzle information {ND(i), NP(i)} is determined based on the next work information, which is JOB information obtained by excluding JOB information whose nozzle transfer end information is "completed" from the production plan JOB information. . Therefore, it is possible to satisfactorily prevent transfer of duplicate nozzles on the same type of tray T. FIG.
Further, in the nozzle management machine 6, nozzle management information is stored as shown in FIG.

In the above embodiment, the nozzle information {ND(i), NP(i)} corresponding to the tray T is determined by communication with the host PC 8 (production planning JOB information) in the nozzle management machine 6. However, it is also possible to store the production plan JOB information in the nozzle management machine 6 in advance, in which case it is not necessary to communicate with the host PC 8 .
Also, the tray information TD of the trays T set in the tray holding units 168 and 170 is transmitted from the nozzle management machine 6 to the host PC 8, and the nozzle information {ND(i), NP(i)} is determined in the host PC 8. can be sent to the nozzle management machine 6. Thus, the execution (role sharing) of each of the nozzle management machine 6 and the host PC 8 is not limited to the above embodiment, and either execution may be performed in either.
Also, the production planning JOB information and JOB list are not limited to the host PC 8, and can be stored in an external device or the like connected to the bus 10. FIG. Furthermore, a PC can be directly connected to the nozzle management machine 6 and stored in the PC.

In the second embodiment, nozzle information {ND(i), NP(i)} is determined in the host PC 8 based on the operator's input and the production planning JOB information, and supplied to the nozzle management machine 6 . Information that can determine the nozzle information {ND(i), NP(i)}, such as JOB name, JOB name, and mounter information, can be selected or input by the operator.
A nozzle transfer program represented by the flow chart of FIG. 13(a) is executed in the nozzle management machine 6, and a nozzle information supply program represented by the flow chart of FIG. 13(b) is executed by the host PC8.
In the host PC 8, a JOB list is displayed on the display 266 in S51. At S52, an operator's input (selection) is awaited. When the operator selects the JOB name {JOB(x)}, in S53, the nozzle information {ND(x), NP(x)} corresponding to JOB(x) is selected and the nozzle management machine 6 Send to Thereafter, in S54, the supply (receipt) of nozzle transfer completion information is awaited.
In the nozzle management machine 6, in S61, it is determined whether or not the tray T is set in either of the tray holding units 168 and 170. If it is set, in S62 nozzle information {ND(i), NP (i)} supply is awaited. When the nozzle information {ND(x), NP(x)} is supplied from the host PC 8, the nozzles are transferred based on the nozzle information {ND(x), NP(x)} in S63. will be When the transfer of the nozzles is completed, in S64, the nozzle transfer completion information "Completed" is transmitted, and in S65, the supply of mounting machine information is awaited.
When the host PC 8 receives the nozzle transfer end information, the determination in S54 becomes YES, the mounting machine information corresponding to JOB(x) is transmitted in S55, and the nozzle corresponding to JOB(x) is transmitted in S56. The transfer end information is changed from "unfinished" to "finished" and stored.
When the mounter information is supplied to the nozzle management machine 6, the determination in S65 becomes YES, and in S66, the completion of the nozzle transfer is displayed in association with the mounter.

Thus, in this embodiment as well, the operator does not need to perform troublesome nozzle transfer work, and the nozzles corresponding to the tray T can be properly placed.
In this embodiment, when the nozzles are out of stock, it is possible to notify that effect. The operator can again select another JOB. It is also possible to send information indicating that the nozzle is out of stock to the host PC 8 so that the host PC 8 searches for other nozzle information {ND(i), NP(i)}.
In addition, a JOB list can be displayed on the display 252 of the nozzle management machine 6, and an operator can enter the information in the nozzle management machine 6. FIG.
As described above, in this embodiment, the control device 14 and the host PC constitute an input information dependent nozzle management control device.

In the nozzle management machine 6, the nozzles N are transferred to the pallet P and accommodated in the pallet P for the tray T after use, not limited to the transfer of the nozzles for setup change, for example, when the mounting work is completed. The present invention can also be applied to storage in the device 74 .
For example, the operator takes out the tray T containing the used nozzles N from the mounter, sets it in the tray holding section 168, and selects or inputs the job name corresponding to the tray T. FIG. In the nozzle management machine 6, the nozzles N placed on the tray T are transferred to the pallet P. In this case, the nozzle type information ND(i) etc. of the nozzles N transferred to the pallet P can be obtained from the nozzle information {ND(i), NP(i)} corresponding to . There is an advantage that it is not necessary to image the nozzle N by the transfer head 200 and read the ND code each time.
In addition to the above embodiments, the present invention can be implemented in various modes with various modifications and improvements based on the knowledge of those skilled in the art.
