S10 is a process on the management device side, and steps S101,
S102 is a process of the control unit on the mounting machine side. Steps S201 to S204 indicate an operation by the operator.

The operation of the operator and the processing corresponding to the operation will be described with reference to this figure. First, when the operator sets the reel 21 which is an assembly of parts on the tape feeder 4, in addition to the setting operation, immediately before or immediately after the setting operation, Then, the user operates the bar code reader 30 to read the bar codes of the recording media 23 and 24 attached to the reel 21 and the tape feeder 4, respectively. This allows
The component identification information and the feeder identification information read by the barcode reader 30 are transmitted. The management device 31 receives these information in step S1, and stores the relationship between the set reel 21 and the tape feeder 4 in step S2 based on the information.

Next, when the operator sets the tape feeder 4 after mounting the reels on the component supply unit 3 of the mounting machine, in addition to the setting operation, the bar code reader 30 is operated immediately before or immediately after the set operation. The barcode of the recording medium 24 attached to the feeder 4 and the barcode of the recording medium 25 attached to the mounting position with respect to the tape feeder 4 are read. Thereby, the feeder identification information and the mounting position identification information read by the barcode reader 30 are transmitted.

The management device 31 receives the information in step S3, and stores the relationship between the feeder mounting position and the tape feeder 4 set in that position in step S4 based on the information.

After the setting of the reel 21 and the feeder 4 is completed, as a process for starting production, an operator inputs a production model by an input unit. The preferred arrangement of the feeder 4 according to the various printed circuit boards is obtained in advance by a method such as optimization by computer analysis and stored in the control unit 32 of the mounting machine and the management device 31. Then, when the production model is input, the control unit 32 of the mounting machine changes the data used for mounting according to the production model and sends the data of the production model to the management device 31.

In step S5, the management device 31 reads out an appropriate feeder arrangement corresponding to the production model from the memory. Then, in step S6, the actual feeder arrangement determined based on the processing in steps S2 and S4 is compared with the data of the preferred feeder arrangement read from the memory, and in step S7, the feeder arrangement in which the actual feeder arrangement is preferable It is determined whether or not it matches the arrangement.

If the actual feeder arrangement does not match the proper feeder arrangement, the collation result in this case is transmitted to the control unit 32 of the mounting machine in step S8.
The information indicating the mismatch and the location indicating the mismatch are transmitted. The control unit 32 receives the information and displays a message corresponding to the information on the display 36 (step S102). Then, the operator corrects the set of the feeders 4 in accordance with the above message, and reads the barcodes of the recording media 24 and 25 attached to the corresponding tape feeder 4 and the feeder mounting position after the correction. By operating 30 (step S204), the information is transmitted.

The management device 31 receives the new bar code read information in step S9, performs the collation in step S6 and makes the determination in step S7 again, and repeats step S7 until the actual feeder arrangement matches the proper feeder arrangement.
Steps S6 to S9 are repeated. If the actual feeder arrangement matches the proper feeder arrangement, the collation result is sent to the control unit 32 of the mounting machine in step S10.
And the display 36 is displayed on the display 36 to end the process.

According to the apparatus of the present embodiment as described above,
When the reel 21 is set on the tape feeder 4, information on the recording media 23 and 24 attached to the reel 21 is read by the barcode reader 30, and when the tape feeder 4 is set at the feeder mounting position of the component supply unit 3. The control device 31 automatically checks the actual feeder arrangement (the relationship between the components, the feeders, and the mounting positions) by reading the information of the recording media 24 and 25 attached to the respective devices by the barcode reader 30. And
Matching with the appropriate feeder arrangement is performed.

Therefore, the reel 21 and the tape feeder 4
It can be easily confirmed whether or not the setting has been performed properly. If there is a setting error, it is displayed on the display 36 of the mounting machine, so that the error is not overlooked.

The component identification information is recorded on the recording medium 23 of the reel 21, the feeder identification information is recorded on the recording medium 24 of the tape feeder 4, and the mounting position identification information is recorded on the recording medium 25 of each feeder mounting position of the component supply unit 3. The management device 31 creates data indicating these correspondences based on the information read from the recording media 23, 24, and 25. The reels 21 are set on the tape feeder 4, for example. Also, troublesome processing such as rewriting the recorded contents of the recording medium 24 of the tape feeder 4 is not necessary even when is replaced. That is,
Management including recording of information on a recording medium and reading of information can be performed easily and reliably.

By the way, when using the management device of the present embodiment, the data of the components to be mounted is input in advance for each board so that the components mounted on each board by the management device 31 or the like as shown in FIG. A list including a feeder set position, a part name, a bar code, and the like is created, and the list is printed out by the management device 31. When the list is used by the operator to search for parts in a parts store, The work of searching for the mounting position when setting the camera can be facilitated.

That is, if the list printed out by the management device 31 is placed on the wall surface of the parts store, the parts can be searched while referring to the list when searching for parts in the parts store. Also, if the above-mentioned list is pasted on the side surface of the component supply unit 3 of the mounting machine main body, when setting the feeder 4 in the component supply unit 3, it is possible to search for the mounting position with reference to this list.

Further, in these cases, collation can be performed using the barcode reader 30. For example, when searching for a part in the parts storage, as shown in FIG. 10, first, the barcode of the corresponding part in the list or the barcode of the empty reel 21 is read (step S3).
01), the barcode is temporarily stored in a memory in the barcode reader 30 (step S302). Next, the barcode of the found component is read (step S30).
3) The barcode reader 30 compares the part with the temporarily stored part (step S304), and notifies the user of the coincidence or non-coincidence by display and sound according to the comparison result (step S305).

By such a process, if there is a mismatch, the part can be searched again and the mistake can be eliminated.

When the feeder 4 is set in the component supply section 3, as shown in FIG. 11, first, a bar code of the reel 21 mounted on the feeder 4 is read (step S401), and the bar code is read by the bar code reader 30. (Step S402).
Next, the barcode of the component corresponding to the set position to be attached is read from the list (step S40).
3) The barcode reader 30 compares the part with the temporarily stored part (step S404), and notifies the user of the coincidence or non-coincidence with a display and a sound according to the comparison result (step S405).

According to such processing, when the two do not match, the feeder set position is searched again, and the wrong set position can be prevented.

In the above-described embodiment, the recording media 23, 2 using bar codes are respectively provided at the feeder mounting positions of the reel 21, the tape feeder 4, and the component supply unit 3.
4 and 25 are attached, a recording medium using a barcode is attached to the side of the tape feeder 4, and a recording medium composed of a ROM is attached to the upper end or the like. A reading means for reading the recorded contents of the ROM may be provided at each feeder mounting position of the component supply unit 3. Also in this embodiment, a recording medium using a barcode is attached to the reel 21. The first information transmitting means is constituted by the barcode reader, and the second information transmitting means is constituted by the reading means at each feeder mounting position.

In this case, as shown in FIG. 12, when the operator sets the feeder at the feeder mounting position of the component supply unit of the mounting machine (step S202 '), the processing at the mounting machine side is performed at the position where the feeder is set. The feeder identification information is read from the ROM by the reading means (step S110). Then, the feeder identification information and the mounting position identification information obtained by checking which position the reading unit has read are transmitted from the control unit of the mounting machine to the management device. The management device receives the read information and the like, and stores the relationship between the feeder mounting position and the tape feeder set at that position based on the read information (step S3 '). Other processes are the same as those in the flowchart of FIG.

According to this embodiment as well, the arrangement of the tape feeders in the component supply section can be easily and reliably managed.
