For example, when the movement of the lock lever 9 stopped at the third position is detected by the operation sensor 82, the second data processing unit 56 causes the communication unit 58 to communicate the communication data indicating that the locking mechanism 28 is released from the feeder container 105. When the operation sensor 82 detects the movement of the lock lever 9 stopped at the fourth position, the second data processing unit 56 causes the communication unit 58 to communicate communication data indicating that the lock mechanism 28 is fixed to the feeder container 105 .

[0082] The storage unit 57 stores the state data of the conveying mechanism 30 based on the first data processing. In the present embodiment, the storage unit 57 stores the position data of the sprocket 32 ​​at the time when the human sensor 81 detects the approach or contact of the operator.

[0083] The communication unit 58 communicates with the feeder container 105 based on the second data processing. The communication unit 58 sends the communication data to the feeder container 105 via the communication terminal 29. In the present embodiment, the communication unit 58 sends the communication data indicating the operation of the locking mechanism 28 to the feeder container 105 when the operation sensor 82 detects the operation of the locking lever 9.

[0084] When the human sensor 81 detects the operator and the operation sensor 82 does not detect the operation of the lock lever 9, the first data processing is performed. When the human sensor 81 detects the operator and the operation sensor 82 detects the operation of the lock lever 9, the second data processing is performed.

[0085] [action]

[0086] Fig. 9 1 is a flowchart showing the operation of the feeder 10 according to the present embodiment. With the locking mechanism 28 fixed to the feeder container 105, the feeder 10 moves the carrier tape T and sequentially conveys a plurality of components C to the supply position SM. The mounting head 5 mounts the components C supplied to the supply position SM on the substrate P disposed at the mounting position DM.

[0087] When the operator is not close to the handle 8 or is not in contact with the handle 8, the human sensor 81 outputs detection data indicating that the operator is not close to or in contact with the handle 8 to the control device 50. When the operator is close to the handle 8 or is in contact with the handle 8, the human sensor 81 outputs detection data indicating that the operator is close to or in contact with the handle 8 to the control device 50. The first detection data acquisition unit 51 acquires the detection data of the human sensor 81 (step S1).

[0088] When the lock lever 9 is not operated, the operation sensor 82 outputs detection data indicating that the lock lever 9 is not operated to the control device 50. When the lock lever 9 is operated, the operation sensor 82 outputs detection data indicating that the lock lever 9 is operated to the control device 50. The second detection data acquisition unit 52 acquires the detection data of the operation sensor 82 (step S2).

[0089] The first data processing unit 55 determines whether the operator approaches or touches the handle unit 8 based on the detection data of the human sensor 81 acquired by the first detection data acquisition unit 51 (step S3 ).

[0090] For example, when the components C are mounted on the substrate P, the number of components C held on the carrier tape T decreases. The operator approaches the feeder 10 to replace the carrier tape T. When the human sensor 81 detects the approach of the operator, it outputs the detection data indicating that the operator approaches the handle 8 to the first detection data acquisition unit 51. The first data processing unit 55 can determine whether the operator approaches or touches the handle 8 based on the detection data of the human sensor 81 acquired by the first detection data acquisition unit 51.

[0091] If it is determined in step S3 that the operator has not approached or touched the handle portion 8 (step S3: No), the process returns to step S1.

[0092] If it is determined in step S3 that the operator approaches or touches the handle 8 (step S3: Yes), the first data processing unit 55 starts the first data processing. As described above, in this embodiment, the first data processing includes a process of storing the state data indicating the state of the conveying mechanism 30 in the storage unit 57. The first data processing unit 55 stores the state data of the conveying mechanism 30 in the storage unit 57 (step S4).

[0093] In the present embodiment, the first data processing unit 55 performs, as the first data processing, a process of storing the position data of the sprocket 32 ​​at the time when the human sensor 81 detects the approach of the worker in the storage unit 57 .

[0094] The second data processing unit 56 determines whether the lock lever 9 has been operated based on the detection data of the operation sensor 82 acquired by the second detection data acquisition unit 52 (step S5 ).

[0095] For example, when replacing the carrier tape T, the fixing of the locking mechanism 28 and the feeder container 105 is released. The operator operates the locking lever 9 to release the fixing of the locking mechanism 28 and the feeder container 105. When the operation sensor 82 detects the operation of the locking lever 9, it outputs the detection data indicating that the locking lever 9 is operated to the second detection data acquisition unit 52. The second data processing unit 56 can determine whether the locking lever 9 is operated based on the detection data of the operation sensor 82 acquired by the second detection data acquisition unit 52.

[0096] If it is determined in step S5 that the lock lever 9 has not been operated (step S5: No), the process returns to step S1.

[0097] If it is determined in step S5 that the lock lever 9 is operated (step S5: Yes), the second data processing unit 56 starts the second data processing. As described above, in this embodiment, the second data processing includes processing for communicating communication data between the communication unit 58 and the feeder container 105. The second data processing unit 56 sends the communication data from the communication unit 58 (step S6).

[0098] In this embodiment, the second data processing unit 56 performs the following processing as the second data processing, namely: when the operation sensor 82 detects the operation of the locking rod 9, communication data indicating that the locking mechanism 28 is actuated and the fixation between the locking mechanism 28 and the feeder container 105 is released is sent to the feeder container 105.

[0099] As described above, when the feeder 10 is taken out from the feeder container 105, the data processing of the feeder 10 is completed.

[0100] When the feeder 10 is mounted on the feeder container 105, the first data processing is similarly started based on the detection data of the human sensor 81, and the second data processing is started based on the detection data of the operation sensor 82. In this case, the first data processing may be a processing of storing the state data indicating the state of the conveying mechanism 30 in the storage unit 57, or a processing of storing the number of components C held on the carrier tape T newly connected to the feeder 10. The second data processing may be a processing of sending communication data indicating that the locking lever 9 is operated and the locking mechanism 28 and the feeder container 105 are fixed to each other.

[0101] [Effect]

[0102] As described above, according to the present embodiment, the human sensor 81 is provided on the handle 8. When the human sensor 81 detects the approach or contact of the operator, the first data processing is started. This can prevent the feeder 10 from executing a plurality of data processing at the same time.

[0103] An operation sensor 82 is provided to detect the operation of the lock lever 9 for operating the lock mechanism 28. When the operation sensor 82 detects the operation of the lock lever 9, the second data processing starts. This can prevent the first data processing and the second data processing from being executed simultaneously in the feeder 10.

[0104] For example, if the first data processing and the second data processing are executed simultaneously due to the operation of the lock lever 9, the data processing load of the control device 50 increases. In addition, there is a case where the lock lever 9 is operated multiple times unnecessarily. When the first data processing and the second data processing are executed simultaneously due to the operation of the lock lever 9, if the lock lever 9 is operated multiple times unnecessarily, the control device 50 will execute the first data processing and the second data processing multiple times unnecessarily, and the data processing load in the control device 50 increases.

[0105] For example, there is a case where the operator's clothes are caught on the lock lever 9 or the operator's hand touches the lock lever 9, causing the operator to inadvertently operate the lock lever 9. In this case, the lock lever 9 is inadvertently operated multiple times. In addition, in the present embodiment, in a state where no external force acts on the lock lever 9, the lock lever 9 is arranged in the third position by the elastic force of the elastic member (not shown) connected to the lock lever 9, and the hook 28A is arranged in the first position by the elastic force of the spring 28B. For example, there is a case where, even if the operator wants to operate the lock lever 9 so that the lock lever 9 moves from the third position to the fourth position, the lock lever 9 returns to the third position due to the operator's hand slipping or operation error. In the case where the lock lever 9 returns to the third position, the operator needs to operate the lock lever 9 multiple times so that the lock lever 9 is arranged in the fourth position. In this way, even if the operator wants to operate the lock lever 9, the lock lever 9 is inadvertently operated multiple times when the lock lever 9 is not fully operated.

[0106] In this embodiment, a human sensor 81 and an operation sensor 82 are provided, and when the human sensor 81 detects an operator, the first data processing is performed, and when the operation sensor 82 detects the operation of the lock lever 9, the second data processing is performed. Thus, even if the lock lever 9 is inadvertently operated, the first data processing is not performed. Therefore, it is possible to suppress an increase in the load of data processing in the control device 50.

[0107] In the present embodiment, the first data processing includes a process of storing the state data of the conveying mechanism 30 in the storage unit 57. Thus, the control unit 54 can control the conveying mechanism 30 after the carrier tape T is replaced based on the state data of the conveying mechanism 30 stored before the carrier tape T is replaced. For example, when the state data of the conveying mechanism 30 includes the position data of the sprocket 32 ​​at the time when the human sensor 81 detects the operator, the control unit 54 can control the conveying mechanism 30 after the carrier tape T is replaced based on the state data of the sprocket 32 ​​stored before the carrier tape T is replaced.

[0108] In the present embodiment, the second data processing includes processing for communicating communication data with the feeder container 105. Thus, the feeder container 105 can recognize whether the feeder 10 has been mounted on the feeder container 105 based on the communication data.

[0109] When the human sensor 81 detects an operator and the operation sensor 82 does not detect the operation of the lock lever 9, the first data processing is executed. When the human sensor 81 detects an operator and the operation sensor 82 detects the operation of the lock lever 9, the second data processing is executed. Thus, it is possible to suppress the first data processing and the second data processing from being executed simultaneously in the feeder 10.
