On the contrary, when the supply control unit 61 switches the switch SW1 from the closed state to the open state, the power transmission circuit PT0 is opened and the supply of AC power to the power receiving circuit PR0 is stopped.

In the power receiving circuit PR0, the unit side power receiving unit 72 and the power receiving side resonance unit RR1 are connected in parallel on the input side of the power conversion unit 73, and the power receiving side resonance circuit is formed. For example, a coil can be used for the unit-side power receiving unit 72. A capacitor can be used for the power receiving side resonance portion RR1. The power conversion unit 73 may include a known rectifier circuit, booster circuit, and inverter circuit. The AC power supplied from the power transmission circuit PT0 is rectified by a rectifier circuit such as a diode bridge, for example. The DC power rectified by the rectifier circuit is boosted to a predetermined voltage by the booster circuit. The boosted DC power is converted into AC power having a predetermined voltage of Vac by the inverter circuit.

The predetermined voltage Vac can be set to, for example, the supply voltage of a commercial power source (for example, 100V, 120V, 200V, etc.). In this case, the unit 70 can also supply driving power to an electric device driven by a commercial power source. As described above, the unit 70 of the present embodiment includes a power conversion unit 73 that converts the power supplied by the non-contact power supply from the board working machine WM0 into AC power of a predetermined voltage Vac. Therefore, the unit 70 can supply various AC powers from the power conversion unit 73, and the unit 70 can be used as a general-purpose power source.

The unit-side guide roller 712 is provided on the unit-side bracket 711 and rotatably engages with the upper portion of the first rail 41. The unit-side guide roller 712 corresponds to the first guide roller 512 of the movable portion 51. The unit-side traveling roller 713 is provided on the unit-side bracket 711 in pairs so as to be able to roll a pair of side wall portions of the traveling groove 46 formed in the groove bottom portion of the first rail 41 in pairs in the Y direction. The unit-side traveling roller 713 corresponds to the traveling roller 514 of the movable portion 51.

For example, the operator can carry in the unit-side movable portion 71 from one end side of the travel path 40R shown in FIG. 1 and drive the unit-side movable portion 71 to the area NA0 of the travel path 40R. In this case, the operator can also use the unit 70 while traveling the unit-side movable portion 71 in the area NA0 of the travel path 40R. Further, a regulating member for restricting the movement of the unit-side movable portion 71 may be provided in the region NA0 of the traveling path 40R.

As described above, since the unit 70 of the present embodiment is detachably provided in the region NA0 where the movable portion 51 is not scheduled to travel in the predetermined time zone, the unit 70 can be easily installed and removed.

2. An example of the effect of the first embodiment The power supply system 60 includes a supply control unit 61. Therefore, the power supply system 60 is paired with the unit 70 other than the movable portion 51 provided in the region NA0 in which the movable portion 51 is not scheduled to travel in a predetermined time zone in at least a part of the traveling path 40R. The electric power supplied by the non-contact power supply from the board work machine WM0 can be supplied.

3. 3. Technical concept derived from the present disclosure Here, various electric units are used in the board-to-board working machine provided in the board production line. However, it may be difficult to prepare a power source for driving the unit around the board working machine. Further, even if it is possible to prepare a power supply, the management of the power supply may become complicated. Further, for example, when a rechargeable battery is mounted on the unit, it is necessary to charge the battery, replace the battery due to deterioration of the battery, and the like, which may complicate the work. In addition, the substrate production line may be provided with a power supply system in which movable parts can travel along the travel path, and there is a demand for further utilization of the power supply system.

As shown in FIG. 10, the transfer device 201 moves along the transfer path 217 on the floor 215 (see FIG. 11) provided with the production system 200, and replaces the feeder 20. FIG. 11 is a schematic view of a state in which the transfer device 201 is moved to a position where the feeder storage device BS0 and the feeder 20 can be delivered (hereinafter, may be referred to as a replacement position) as viewed from the side in the X direction. .. Further, FIG. 12 is a schematic view of a state in which the transport device 201 of FIG. 11 is arranged at the exchange position, as viewed from above. FIG. 13 shows the configuration of the power supply system 202 of the second embodiment.

As shown in FIGS. 11 to 13, the transport device 201 includes a device main body portion 219 and a mounting portion 223. A battery 221 is built in the device main body 219. At the lower part of the device main body 219, a moving unit 225 for moving the device main body 219 by the electric power received from the battery 221 is provided. The moving unit 225 is, for example, a moving device that rotates a tire on the floor 215 by a motor. The moving unit 225 moves the device main body unit 219 based on the control of the control unit 231 of the transport device 201. The configuration of the moving portion 225 is not limited to the configuration including tires, and may be a configuration using caterpillars or a configuration using compressed air such as hovercraft.

The mounting portion 223 is fixed to the upper part of the device main body portion 219, for example. In the transfer device 201 of the present embodiment, a plurality of feeders 20 are put in the magazine 227, and the magazine 227 is placed on the mounting portion 223 and conveyed. The magazine 227 is formed, for example, in a substantially cubic box shape having an opening 227A having one surface opened. The magazine 227 is formed in a size such that a plurality of feeders 20 can be inserted through the opening 227A. In the magazine 227, for example, a slot connected to each feeder 20 is provided. The plurality of feeders 20 are conveyed by the transfer device 201 together with the magazine 227 in a state of being mounted in this slot, for example.

The mounting portion 223 is provided with a plurality of rollers 229 for moving the magazine 227. The control unit 231 of the transfer device 201 is connected to the roller drive unit 233, the power receiving unit 235, the power supply board 237, the communication unit 239, and the position acquisition device 240 in addition to the moving unit 225 described above (see FIG. 13). The control unit 231 is, for example, a computer-based device including a CPU, RAM, ROM, and the like. The roller drive unit 233 is a drive device including a motor and an amplifier for rotating the roller 229. By controlling the roller drive unit 233, the control unit 231 can rotate the plurality of rollers 229 and move the magazine 227 in one direction (for example, in the Y direction shown in FIG. 11).

Further, the feeder storage device BS0 is provided with an arrangement unit 228 for arranging a plurality of magazines 227 (two in the example shown in FIG. 12). Each arrangement portion 228 is provided with a plurality of rollers 241 for moving the magazine 227. The transfer device 201 and the feeder storage device BS0 execute the delivery of the magazine 227 by rotating the rollers 229 and 241 with the transfer device 201 arranged at the exchange position shown in FIG. 11 (see arrow 243 in FIG. 11). ). The magazine 227 arranged in the feeder storage device BS0 is connected to the feeder storage device BS0 via the connection unit 245 provided in the arrangement unit 228. As a result, the feeder 20 is in a state of being able to communicate with the line control device LC0 and the management device 211 via the slot of the magazine 227. The transfer device 201 and the feeder storage device BS0 may individually deliver the feeder 20 without using the magazine 227. In this case, the feeder storage device BS0 may not include the connecting portion 245 and may include a slot for directly connecting the feeder 20 without going through the magazine 227. Further, the holding portion 551 (see FIG. 3) of the movable portion 51 replaces the feeder 20 with respect to the magazine 227 arranged in the feeder storage device BS0. The holding portion 551 takes out or inserts the feeder 20 from the opening 227A of the magazine 227, and replaces the feeder 20.

The feeder 20 is an example of the work related to the substrate working machine of the present disclosure. The work to be conveyed by the transfer device 201 is not limited to the feeder 20, and may be, for example, a suction nozzle used in the mounting head 30, a squeegee for solder application used in the printing machine 203, or the like. Therefore, as the work of the present disclosure, various members used in the anti-board working machine, for example, exchange elements detachably mounted on the anti-board working machine can be adopted.

The feeder storage device BS0 of this embodiment can supply electric power to the transfer device 201. As shown in FIG. 13, the power supply system 202 of the second embodiment includes a transfer device 201 and a power supply device 250. The power supply device 250 includes a power transmission unit 247 and a supply control unit 249. For example, a power receiving unit 235 is provided at a position of the mounting unit 223 on the side of the feeder storage device BS0 in the Y direction. The first rail 41 of the feeder storage device BS0 is provided with a power transmission unit 247 of the power supply device 250. The power receiving unit 235 can receive electric power from the power transmitting unit 247 by, for example, an electromagnetic coupling type non-contact power supply. The power transmission unit 247 switches between starting and stopping the power supply to the power receiving unit 235 based on the control of the supply control unit 249 of the power supply device 250.

The configuration of the power receiving unit 235, the power transmission unit 247, and the supply control unit 249 is not particularly limited. For example, the power receiving unit 235, the power transmission unit 247, and the supply control unit 249 may use the same configurations as the power receiving unit 52, the power transmission unit 45, and the supply control unit 61 of the first embodiment. The power receiving unit 235 of the transport device 201 may be inserted into the U-shaped first rail 41 (see FIG. 3) as in the first embodiment (see FIG. 9). The transport device 201 may include a movable power receiving unit 235. The transport device 201 moves to the replacement position, moves the mounting portion 223 to the upper part of the first rail 41, and then inserts the power receiving portion 235 from the mounting portion 223 into the first rail 41. For example, in FIG. The power receiving unit 235 inserted as shown may be rotated by 90 degrees to receive power from the power transmitting unit 45.

Alternatively, the feeder storage device BS0 may include the power transmission unit 247 for the transport device 201 separately from the power transmission unit 45 for the traveling device 50. For example, the power transmission unit 247 may be provided on the upper portion of the first rail 41, a pair of side wall portions (side walls on the transport device 201 side) of the first rail 41, or the bottom portion of the first rail 41. Further, the supply control unit 249 may be the same device as the supply control unit 61 of the above embodiment and may be provided in the line control device LC0. Alternatively, the supply control unit 249 may be provided in the feeder storage device BS0, the management device 211, the component mounting machine 10, and the like in a device different from the supply control unit 61.

The control unit 231 of the transfer device 201 is arranged on the transfer path 217 that moves by the moving unit 225 and conveys the feeder 20, and receives electric power from the feeder storage device BS0 that transfers the feeder 20 by the power receiving unit 235. The control unit 231 charges the battery 221 with the electric power received from the feeder storage device BS0. More specifically, the power supply board 237 of the transport device 201 includes, for example, an AC / DC circuit, a rectifier circuit, a transformer circuit, and the like, and is connected to the power receiving unit 235. When the transfer device 201 reaches the replacement position, the control unit 231 controls the roller drive unit 233 to transfer the magazine 227 between the feeder storage device BS0 and the mounting unit 223. The control unit 231 receives electric power from the feeder storage device BS0 to the power receiving unit 235 while the magazine 227 is being delivered. Based on the control of the control unit 231, the power supply board 237 converts the alternating current received by the power receiving unit 235 into a direct current (charging voltage of the battery 221) and supplies it to the battery 221. As a result, the battery 221 of the transport device 201 can be charged with the electric power received from the feeder storage device BS0 by the non-contact power supply during the replacement work of the magazine 227. Further, since the transfer device 201 is stopped during the delivery of the magazine 227, electric power can be stably supplied from the feeder storage device BS0 to the transfer device 201.

The feeder storage device BS0 is an example of the external device of the present disclosure. The external device is not limited to the feeder storage device BS0. For example, various devices on the transport path 217 to which the transport device 201 shown in FIG. 10 moves can be adopted. The external device may be a printing machine 203, a printing inspection machine 205, a component mounting machine 10, a reflow furnace 207, a substrate appearance inspection machine 209, or the like. For example, the transfer device 201 may receive electric power from the printing machine 203 when the replenishing solder or squeegee is conveyed to the printing machine 203 as a work. Further, the transport device 201 may receive electric power from the component mounting machine 10 when the suction nozzle is transported to the component mounting machine 10 as a work.

Further, the transfer device 201 may receive electric power from an external device other than the board-to-board work machine such as the printing machine 203. As shown in FIG. 10, the transfer device 201 moves, for example, between the storage chamber 251 for storing the feeder 20 and the magazine 227 and the substrate production line 1. For example, a feeder management device 253 and a feeder exchange device 255 are arranged in the storage room 251. The feeder management device 253 is a device that manages the feeder 20 and executes reading of a barcode that identifies the feeder 20 and the like. The feeder exchange device 255 is a device that transfers the magazine 227 to and from the transfer device 201, and exchanges / replenishes the feeder 20 with respect to the magazine 227. The feeder management device 253 and the feeder switching device 255 are connected to the network 213 and can communicate with the management device 211. The feeder exchange device 255, for example, transfers the magazine 227 to and from the transfer device 201, replenishes the feeder 20, and the like based on the control of the management device 211. The transport device 201 may receive electric power from the feeder switching device 255 when the feeder switching device 255 and the magazine 227 are delivered.

Further, the production system 200 is provided with, for example, a feeder stock device 257 for stocking a magazine 227 and a feeder 20 corresponding to each substrate production line 1. The feeder stock device 257 is configured so that, for example, a plurality of magazines 227 can be placed, and is connected to the network 213 by wireless communication. In the feeder stock device 257, a magazine 227 equipped with a feeder 20 that is no longer used in the substrate production line 1 and a magazine 227 equipped with a feeder 20 to be used for the next and subsequent productions are arranged. The feeder stock device 257 transfers the magazine 227 to and from the transfer device 201, for example, under the control of the management device 211. The transfer device 201 may receive electric power from the feeder exchange device 255 when the feeder stock device 257 and the magazine 227 are delivered. Therefore, the external device of the present application is not limited to the board-to-board work machine that executes the board-to-board work on the substrate 90, and various devices on the transfer path 217 to which the transfer device 201 moves can be adopted.

Further, as shown in FIG. 13, the transport device 201 includes a communication unit 239. The communication unit 239 is connected to the network 213 by, for example, wireless communication such as a wireless LAN or Bluetooth (registered trademark). Further, the position acquisition device 240 is a device that acquires the current position of the transfer device 201. The configuration of the position acquisition device 240 is not particularly limited. For example, using sensors such as LIDAR and millimeter-wave radar, map data in which the topography around the transport path 217 and the transport path 217 is detected in advance is generated. The position acquisition device 240 confirms the terrain by comparing the real-time detection information such as LIDAR with the map data while the transport path 217 is moving, compares the movement amount of the moving unit 225 (tire) with the map data, or The current position of the transport device 201 can be acquired by confirming the information combining them. Further, for example, the position acquisition device 240 detects the position of the access point of the wireless LAN in the network 213 and the processing result of the image of the transport path 217 by wireless communication with the board working machine of the board production line 1. The current position of the transfer device 201 may be acquired based on the position, the movement information of the transfer device 201, and the like. Alternatively, the position acquisition device 240 may be provided with a GPS receiver or the like and may be configured to acquire the current position by GPS. Further, the transfer device 201 does not have to include the position acquisition device 240. The transport device 201 transports, for example, by reading a magnetic tape, a colored tape, a two-dimensional code, etc. previously attached to the floor 215 on which the substrate production line 1 is arranged with a reading device, capturing an image with a camera, and detecting the tape. The route 217, the stop position (start or goal), or the like may be determined. Moreover, you may combine the above-mentioned methods.

The control unit 231 acquires map information of the floor on which the board production line 1 is installed from the management device 211, for example, through the communication unit 239. The control unit 231 controls the self-propelling of the own device based on the current position of the transfer device 201 acquired from the position acquisition device 240 and the map information. For example, the control unit 231 acquires information on the destination and the relay point from the management device 211, and sets the transport route 217 based on the acquired information on the destination and the map information. The control unit 231 travels on the set transport path 217 while periodically notifying the management device 211 of the current position of the own device, for example. The management device 211 controls the feeder exchange device 255, the feeder stock device 257, and the like based on the position information acquired from the transfer device 201. For example, when the transfer device 201 reaches the position of the feeder exchange device 255, the management device 211 causes the feeder exchange device 255 to start supplying electric power to the transfer device 201. Therefore, the management device 211 is an example of the supply control unit of the present disclosure. The feeder switching device 255 and the like do not have to change the power supply based on the control of the management device 211. For example, the feeder exchange device 255 may be configured to include a sensor in its own device and start supplying electric power when the sensor detects that the transfer device 201 is approaching the exchange position. In this case, the feeder switching device 255 or the like may be provided with a supply control unit.

The control unit 231 notifies, for example, that it has reached the line control device LC0 of the board production line 1 when it reaches the front of the feeder storage device BS0 of any board production line 1. When the line control device LC0 receives the notification from the control unit 231, the line control device LC0 acquires the position of the traveling device 50. For example, when the traveling device 50 moves to the front of the component mounting machine 10 and starts the work on the component mounting machine 10, the line control device LC0 notifies the transport device 201 of an instruction to start the replacement work of the magazine 227. When the control unit 231 acquires the replacement work start instruction from the line control device LC0, the control unit 231 controls the moving unit 225 to move to the replacement position shown in FIG. 11 and notifies the line control device LC0 that the replacement position has been reached. .. When the supply control unit 249 of the line control device LC0 receives the notification from the control unit 231, the power transmission unit 247 starts supplying electric power. The transport device 201 charges the battery 221 while replacing the magazine 227. Further, when a predetermined condition is satisfied, the control unit 231 controls the moving unit 225 to move from the exchange position. When the control unit 231 moves from the exchange position, the supply control unit 249 stops the power supply by the power transmission unit 247. The predetermined conditions referred to here are, for example, a condition in which the replacement of the magazine 227 is completed, a condition in which the battery 221 can be charged to the desired amount of charging power, a condition in which the battery 221 can be charged for a desired charging time, and a line control device LC0. This is the condition for obtaining the instruction to move from.

Therefore, the control unit 231 controls the moving unit 225 as the traveling device 50 transfers the feeder 20 to and from the component mounting machine 10, and the magazine between the feeder storage device BS0 and the mounting unit 223. The apparatus main body 219 is moved to an exchange position where the delivery of 227 can be executed. As a result, the transport device 201 can charge the battery 221 while replacing the magazine 227 without affecting the replacement work of the feeder 20 by the traveling device 50.

The device for notifying the information of the traveling device 50 is not limited to the line control device LC0, but may be another device such as the management device 211. Further, the line control device LC0 retracts the traveling device 50 from the front of the feeder storage device BS0 to the front of the component mounting machine 10 in accordance with the arrival of the transfer device 201 even if the feeder 20 has not been replaced. Is also good. Further, the traveling device 50 may detect the presence of the transport device 201 by the motion sensor 57 (see FIG. 3) and determine the timing of returning to the feeder storage device BS0.

Further, the control unit 231 executes a control for adjusting the charging time based on the charging power and the power consumption. More specifically, for example, the transport device 201 travels on the first transport path 217A and the second transport path 217B shown in FIG. 10 as an example. The first transfer path 217A is a path that moves from the position of the feeder exchange device 255 in the storage chamber 251 to the position of the feeder stock device 257 corresponding to the substrate production line 1 at the top of FIG. Further, the second transfer path 217B is a path for moving from the feeder stock device 257 to the feeder storage device BS0 of the top substrate production line 1. For example, the transport device 201 returns to the storage chamber 251 in the order of the first transport path 217A, the second transport path 217B, the second transport path 217B, and the first transport path 217A, starting from the storage chamber 251.

Here, for example, when moving the first and second transport paths 217A and 217B, the magazine 227 is delivered between the feeder exchange device 255, the feeder stock device 257, and the feeder storage device BS0. Charge the battery 221. The amount of electric power of the battery 221 after charging in each of the external devices is defined as the charging electric power. Further, the power consumption is the amount of power of the battery 221 consumed when moving from the feeder exchange device 255 or the like to the position of the destination external device after the magazine 227 is delivered. In this case, the control unit 231 adjusts the time for receiving power from the external device so that the power consumption is smaller than the charging power.

For example, the control unit 231 starts moving when it can charge more charging power than the required power consumption by the next moving destination. For example, when the control unit 231 moves from the feeder exchange device 255 to the feeder stock device 257 in the first transport path 217A, the battery 221 can be charged with charging power equal to or greater than the power consumption consumed by the movement of the first transport path 217A. , The movement is started from the feeder exchange device 255. As a result, it is possible to start to the next destination feeder stock device 257 in the shortest time and improve the efficiency of the magazine 227 replacement work. When the charging power is insufficient due to a stop or the like during movement, the control unit 231 may charge the battery 221 with a feeder stock device 257 or the like in the middle of the first transport path 217A. Further, by enabling the charging of the battery 221 in each external device of the transport path 217 in this way, it is not necessary to provide a charging station only for receiving the battery 221 in the substrate production line 1 or the storage chamber 251. ..

Further, for example, the control unit 231 provides a movable device such as a feeder stock device 257 or a feeder replacement device 255 as compared with the feeder storage device BS0 and the component mounting machine 10 whose charging time is limited by the movement of the traveling device 50 or the like. You may give priority to the charging time in the external device which is not provided. For example, the control unit 231 reciprocates the charging power after being charged by the feeder stock device 257 in the second transport path 217B and returns the charging power from the feeder stock device 257 to the feeder stock device 257 via the feeder storage device BS0. The charging time may be adjusted so that the power consumption exceeds the required power consumption. That is, the destination external device of the present disclosure is not limited to the external device that delivers the magazine 227 next to the arbitrary external device when the magazine 227 is delivered by the arbitrary external device. Various external devices encountered in the transport path 217 after starting from the external device can be employed. As a result, even if the charging time in the feeder storage device BS0 is shortened due to the movement of the traveling device 50, it is possible to reciprocate in the second transport path 217B and return to the feeder stock device 257.

Further, in the power supply device 250 of the second embodiment, when the magazine 227 is delivered between the power transmission unit 247 that supplies power to the power transmission device 201 and the power transmission device 201, the power transmission unit 247 transfers the electric power. A supply control unit 249 for supplying electric power to 201 is provided. As a result, the transport device 201 moving along the transport path 217 can be charged while the magazine 227 is being delivered. Stable power supply can be executed between the external device related to the substrate production line 1 and the transfer device 201.

The supply control unit 249 is not limited to the configuration provided in the line control device LC0. For example, the feeder storage device BS0 or the printing machine 203 may be provided with the supply control unit 249 to control the power transmission from the power transmission unit 247 to the transfer device 201 that has come to work on its own device.

Incidentally, the component mounting machine 10, the printing machine 203, the printing inspection machine 205, the reflow furnace 207, and the substrate appearance inspection machine 209 are examples of the board work machine and the external device of the present disclosure. The traveling device 50 is an example of a movable device. The management device 211 is an example of a supply control unit for the feeder exchange device 255 and the feeder stock device 257.

Electric power is received when the 227 is delivered, and the battery 221 is charged based on the received electric power. As a result, electric power can be stably received from the external device of the substrate production line 1 during the work. In addition, the battery 221 can be charged during work at the destination of the transport path 217, and self-propelled operation using the battery 221 as a drive source can be continued.
