Similarly, a plurality of feeders 26, 28, and 30 are mounted on the mounting machine 14, and a plurality of feeders 32, 34, and 36 are mounted on the mounting machine 16. In the example shown in the figure, a case is shown in which three feeders are mounted on each of the mounting machines 12, 14, and 16, but the number of feeders mounted on the mounting machine is not limited to this. Each feeder 20, 22, 24, 26, 28, 30, 32, 34, 36 is a feeder controller 20a, 22a, 24a, 26a, 28a, 30a, 32a, 34a for controlling the operation of various components. 36a. When the feeders 20, 22, and 24 are mounted on the mounting machine 12, the feeder controllers 20a, 22a, and 24a can communicate with the mounting machine controller 12a. Similarly, when the feeders 26, 28, 30 are mounted on the mounting machine 14, the feeder controllers 26 a, 28 a, 30 a can communicate with the mounting machine controller 14 a, and the feeders 32, 34, 36 are mounted on the mounting machine 16. Then, the feeder controllers 32a, 34a, and 36a can communicate with the mounting machine controller 16a.

  Each of the feeders 20, 22, 24, 26, 28, 30, 32, 34, and 36 supplies components to be mounted on the circuit board B to the mounting machines 12, 14, and 16. The feeders 20, 22, 24, 26, 28, 30, 32, 34, and 36 in the present embodiment are, for example, a predetermined tape at a predetermined feed speed by driving a servo motor with a tape having components attached at predetermined intervals. This is a tape feeder that feeds in order by feed amount.

  The mounting machines 12, 14, and 16 take out the components supplied from the feeders 20, 22, 24, 26, 28, 30, 32, 34, and 36 that are mounted by a component mounting head (not shown). And configured to be mounted on the circuit board B.

  The mounting machine controllers 12 a, 14 a, and 16 a of the mounting machines 12, 14, and 16 can communicate with the production management computer 38. The production management computer 38 controls operations of the mounting machines 12, 14, 16, the feeders 20, 22, 24, 26, 28, 30, 32, 34, 36, the conveyance path 18, and the like.

  In the component mounting system 10 of the present embodiment, a first type of mounting machine can be used as the mounting machines 12, 14, and 16, and a second type of mounting machine can also be used. In this embodiment, the first type mounting machine is an old type mounting machine that has been used conventionally, and the second type mounting machine is a new type that can be used in place of the first type mounting machine. It is a mounting machine.

  Further, in the component mounting system 10 of the present embodiment, the first type of feeder can be used as the feeders 20, 22, 24, 26, 28, 30, 32, 34, and 36, and the second type of feeder can be used. A feeder can also be used. In this embodiment, the first type feeder is an old type feeder that has been used conventionally, and the second type feeder is a new type feeder that can be used in place of the first type feeder. .

  When the feeder of the first type receives a request for feeder information from the mounting machine with the first command, the feeder transmits the feeder information indicating the first type of feeder to the mounting machine. Thereafter, the first type feeder performs the component supply operation of the first aspect and supplies the components to the mounting machine. In the present embodiment, in the component supply operation of the first aspect, the tape to which the component is attached is sent out at a predetermined feed rate (first feed rate), and the component supply operation to the mounting machine is performed. When the feeder of the first type receives a request for feeder information with a command other than the first command, it transmits an abnormal response to the mounting machine.

  When the feeder of the second type receives a request for feeder information with the second command from the mounting machine, the feeder of the second type indicates that the feeder is the second type of feeder. Thereafter, the second type feeder performs the component supply operation of the second mode and supplies the component to the mounting machine. In the present embodiment, in the component supply operation of the second aspect, the tape to which the component is attached is sent out at a predetermined feed speed (second feed speed) that is faster than the first feed speed, and the parts are mounted on the mounting machine. The supply operation is performed. Further, when the feeder of the second type receives a request for the feeder information from the mounting machine with the first command, the feeder of the second type indicates that the feeder is the first type of feeder. Thereafter, the second type feeder performs the component supply operation of the first aspect, that is, feeds the tape with the component attached thereto at the first feeding speed, and supplies the component to the mounting machine.

  When the feeder is mounted, the first type of mounting machine requests feeder information to the feeder using a first command. Thereafter, when the feeder information indicating that the feeder is the first type of feeder is received from the feeder, the component mounting operation of the first aspect adapted to the component supply operation of the first aspect of the feeder is performed. In the component mounting operation of the first aspect, the component is taken out by the head and the component is mounted on the circuit board B in accordance with the operation of the feeder that supplies the component at the first feeding speed.

  When the feeder is mounted, the second type of mounting machine first requests the feeder information with a second command to the feeder. Thereafter, when feeder information indicating that the feeder is of the second type is received from the feeder, the component mounting operation of the second mode adapted to the component supply operation of the second mode of the feeder is performed. In the component mounting operation of the second aspect, the component is taken out by the head and the component is mounted on the circuit board B in accordance with the operation of the feeder that supplies the component at the second feed rate. For this reason, in the component mounting operation of the second aspect, compared with the component mounting operation of the first aspect, the component extraction operation by the head is faster, and the tact time of the component mounting operation is shorter. If the feeder information indicating that the feeder is the second type of feeder is not received from the feeder, the second type of mounting machine then requests the feeder with the first command from the feeder. After that, when feeder information indicating that the feeder is the first type of feeder is received from the feeder, the second type of mounting machine, the component mounting of the first mode adapted to the component supply operation of the first mode of the feeder Perform the action.

  As shown in FIG. 2, when the first type of feeder is mounted on the first type of mounting machine, feeder information is requested from the mounting machine to the feeder with the first command. Then, feeder information indicating that the feeder is of the first type is transmitted from the feeder to the mounting machine. Thereafter, the feeder performs the component supply operation of the first aspect, and the mounting machine performs the component mounting operation of the first aspect corresponding to the component supply operation of the first aspect.

  As shown in FIG. 3, when the second type feeder is mounted on the first type mounting machine, the feeder information is requested to the feeder by the first command from the mounting machine. Then, feeder information indicating that the feeder is of the first type is transmitted from the feeder to the mounting machine. Thereafter, the feeder performs the component supply operation of the first aspect, and the mounting machine performs the component mounting operation of the first aspect corresponding to the component supply operation of the first aspect.

  As shown in FIG. 4, when the first type feeder is mounted on the second type mounting machine, first, feeder information is requested from the mounting machine to the feeder using the second command. Then, an abnormal response is transmitted from the feeder to the mounting machine. Next, the feeder information is requested from the mounter to the feeder by the first command. Then, feeder information indicating that the feeder is of the first type is transmitted from the feeder to the mounting machine. Thereafter, the feeder performs the component supply operation of the first aspect, and the mounting machine performs the component mounting operation of the first aspect corresponding to the component supply operation of the first aspect.

  As shown in FIG. 5, when a second type of feeder is attached to the second type of mounting machine, first, feeder information is requested from the mounting machine to the feeder using a second command. Then, feeder information indicating that the feeder is of the second type is transmitted from the feeder to the mounting machine. Thereafter, the feeder performs the component supply operation of the second aspect, and the mounter performs the component mounting operation of the second aspect corresponding to the component supply operation of the second aspect.

  As described above, in the component mounting system according to the present embodiment, the first type feeder can be mounted and used with respect to the first type mounting machine conventionally used. It is also possible to use with a type of feeder. For this reason, even if the supplier of the component mounting system temporarily ends the production of the first type of feeder and produces only the second type of feeder, the first type of mounting machine is used. Convenience for users who continue to do so is not impaired.

  According to the component mounting system of the present embodiment, the first type feeder that has been conventionally used can be mounted on the second type mounting machine, or the second type feeder is mounted. You can also For this reason, even when the first type of mounting machine is replaced with the second type of mounting machine, the first type of feeder that has been used can be used continuously. . Further, by mounting the second type feeder on the second type mounting machine, it is possible to realize component mounting at a higher speed than in the past.

  The first command and the second command may be different commands communicated by the same communication method, or may be commands communicated by different communication methods. For example, the first command may be a command communicated by an unencrypted communication method, and the second command may be a command communicated by an encrypted communication method.

  In the component mounting system 10 of this embodiment, the production management computer 38 generates a production plan in the component mounting system 10 by executing a component mounting optimization (optimization) program. In the production plan generated by the production management computer 38, the types of parts supplied by the feeders 20, 22, 24, 26, 28, 30, 32, 34, 36 and the feeders 20, 22, 24, 26, 28, 30 are provided. , 32, 34, and 36 and the component mounting operation to be performed by the mounting machines 12, 14, and 16 are specified.

  According to the component mounting system 10 of the present embodiment, when the production management computer 38 generates a production plan by the optimization program, the feeder performs the component supply operation of the first aspect, and the mounting machine has the first aspect. A mode for preferentially specifying the first operation state in which the component mounting operation is performed, and a second operation state in which the feeder performs the component supply operation of the second mode and the mounter performs the component mounting operation of the second mode. The user can select one of the modes in which priority is designated. In the component mounting system 10 according to the present embodiment, a second type of mounting machine and a second type of feeder are required to realize the second operation state. However, if the user does not own both the second type mounting machine and the second type feeder, the second operation state cannot be realized. As described above, the user has a configuration in which the user can select the mode in which the first operation state is specified with priority and the mode in which the second operation state is specified with priority. A production plan that matches the actual situation of the machine and the feeder can be generated. In addition, you may comprise so that selection of the above modes can be performed according to the form of a feeder. For example, when the feeder is a tape feeder, the mode in which the second operation state is designated with priority when the tape width is 12 mm, and the first operation state is prioritized when the tape width is 8 mm or 16 mm. It may be configured so that the user can select the mode to be designated.

  In the component mounting system 10 of the present embodiment, the first operation mode that prioritizes the operation state of the combination of the feeder and the mounting machine specified by the production plan and the operation state that can be realized by the actual feeder and mounting machine are prioritized. It is possible to switch between the second operating modes. Below, each mode is demonstrated, referring the flowchart of FIG.

  In step S2, the production management computer 38 generates a production plan. In step S4, the production management computer 38 determines that the operation state specified in the production plan is an operation state that can be realized by a combination of an actual feeder and mounting machine. Determine whether they match. Information about the combination of the actual feeder and the mounting machine is transmitted from the mounting machine controllers 12a, 14a, 16a to the production management computer 38. When the operation state specified in the production plan matches the operation state that can be realized by the combination of the actual feeder and the mounting machine (in the case of YES in step S4), the process proceeds to step S12 and is specified in the production plan. An instruction is transmitted from the production management computer 38 to the mounting machine controllers 12a, 14a, and 16a so that the feeder and the mounting machine are operated in the operating state.

  If the operation state specified in the production plan does not match the realizable operation state (NO in step S4), the process proceeds to step S6, and the production management computer 38 operates the operation state specified in the production plan. It is determined which one of the first operation mode that prioritizes and the second operation mode that prioritizes the realizable operation state is selected.

  If the first operation mode is selected in step S6, the process proceeds to step S8, and the production management computer 38 issues a warning to the user and prompts replacement of the feeder and the mounting machine. In step S10, the production management computer 38 stands by until the feeder and the mounting machine are replaced. When the feeder and the mounting machine are exchanged, a message to that effect is transmitted from the mounting machine controllers 12a, 14a, 16a to the production management computer 38. When the user replaces the feeder and the mounting machine (YES in step S10), the process proceeds to step S12, and the production is performed so that the feeder and the mounting machine are operated in the operation state specified in the production plan. An instruction is transmitted from the management computer 38 to the mounting machine controllers 12a, 14a, and 16a. In this way, by operating the component mounting system 10 in the first operation mode, the component mounting operation on the circuit board B can be performed according to the production plan generated by the optimization program, and the expected tact time And the actual tact time can be reduced.

  When the second operation mode is selected in step S6, the process proceeds to step S14, and the production management is performed so that the feeder and the mounting machine are operated in an operation state that can be realized by the combination of the actual feeder and the mounting machine. An instruction is transmitted from the computer 38 to the mounting machine controllers 12a, 14a, and 16a. In this case, the actual tact time is different from the tact time expected from the production plan. However, it is possible to perform the component mounting work on the circuit board B by making the best use of the feeder and mounting machine that the user currently has.

  Note that the component mounting system 10 can be configured such that the production management computer 38 regenerates the production plan when the second operation mode is selected. In this case, when the production management computer 38 regenerates the production plan by the optimization program, the operation state that can be realized by the combination of the actual feeder and the mounting machine is designated with priority. Thereafter, an instruction is transmitted from the production planning computer 38 to the mounting machine controllers 12a, 14a, and 16a so that the feeder and the mounting machine are operated in the operation state specified in the regenerated production plan, so as to meet the production plan. In addition, it is possible to perform a component mounting operation on the circuit board B, and it is possible to reduce an error between an expected tact time and an actual tact time.

  Further, when the first operation mode is selected and the production management computer 38 issues a warning prompting the user to replace the feeder and the mounting machine in step S8, the second operation mode is changed from the first operation mode by the user. The component mounting system 10 may be configured to be able to switch to the operation mode. In this case, in the second operation mode after switching, even if the production management computer 38 operates the feeder and the mounting machine in an operation state that can be realized by a combination of the actual feeder and the mounting machine, as in step S14. Alternatively, as described above, the production management computer 38 may regenerate a production plan in accordance with an operation state that can be realized by a combination of an actual feeder and a mounting machine.

  In the above-described embodiment, among the processes performed by the production management computer 38, except for the production plan generation (and regeneration), the mounting machine controllers 12a, 14a, and 16a perform the same. The component mounting system 10 may be configured.
