Description

This invention relates to a component mounting system and a component mounting method, and in particular to a component mounting system and a component mounting method that transport a component supply unit.

Conventionally, a component mounting system that transports a component supply unit is known. Such a component mounting system is disclosed, for example, in Japanese Patent Publication No. 6266621.

The above-mentioned Patent Publication No. 6266621 discloses a component mounting system that includes an automated guided vehicle that transports a feeder (component supply unit) and a component mounting machine on which the feeder is placed. In this component mounting system, a worker in a preparation area prepares the feeder to be transported, and the prepared feeder is transported to the production area by the automated guided vehicle. Then, a worker in the production area supplies the feeder transported by the automated guided vehicle to the component mounting machine.

Patent No. 6266621

Although not specified in the above-mentioned Japanese Patent No. 6266621, in the component mounting system described in the above-mentioned Japanese Patent No. 6266621, the feeder prepared by the worker in the preparation area may be placed on the temporary placement table, and the feeder placed on the temporary placement table may be picked up and transported by the automatic guided vehicle. In this case, the worker in the preparation area may mistakenly place the feeder on the temporary placement table (such as placing the feeder in the wrong placement position on the temporary placement table). In this case, there is a problem in that it is difficult for the worker to efficiently place the feeder (component supply unit) on the temporary placement table (placement device).

This invention has been made to solve the problems described above, and one object of the invention is to provide a component mounting system and a component mounting method that enables an operator to efficiently place a component supply unit on a placement device when a transport robot retrieves the component supply unit from a placement device and transports it to a component mounting device.

In order to achieve the above object, the component mounting system according to first to sixth aspects of the present invention includes a component mounting device that mounts components on a board using a component supply unit, a transport robot that transports the component supply unit to the component mounting device, a placement device in which the multiple component supply units transported by the transport robot are arranged, and a control device that, when the transport robot acquires the component supply unit from the placement device and transports it to the component mounting device, creates a setup list including information representing the placement position in the placement device of the component supply unit to be transported, and notifies an operator of the created setup list. In a component mounting system according to a first aspect of the present invention, each of the component mounting device, the transport robot, and the placement device has a plurality of component supply unit placement units in which the component supply units are placed, and the component mounting device, the transport robot, and the placement device are each configured to be able to place the component supply units in the corresponding component supply unit placement units , and the control device is configured to create a setup list so that the position of the component supply unit placement unit in which the component supply units are placed in the placement device corresponds to the position of the component supply unit placement unit in which the component supply units are placed in the transport robot and the position of the component supply unit placement unit in which the component supply units are placed in the component mounting device. In a component mounting system according to a second aspect of the present invention, the component mounting device, the transport robot, and the placement device are each configured to be able to place the component supply units in corresponding positions, and the control device is configured to create a setup list so that the position of the component supply unit in which the component supply units are placed in the placement device corresponds to the position of the component supply unit in which the component supply units are placed in the transport robot and the position of the component supply unit in the component mounting device.

In the component mounting system according to the first to sixth aspects of the present invention, when a transport robot acquires a component supply unit from a placement device and transports it to a component mounting device, a setup list including information indicating the placement position of the component supply unit to be transported in the placement device is created, and a control device is provided that notifies an operator of the created setup list. This allows the setup list to clearly indicate the placement position of the component supply unit in the placement device to the operator. As a result, it is possible to prevent the operator from making a mistake in placing the component supply unit in the placement device (such as placing the component supply unit in a wrong placement position in the placement device). This allows a component mounting system to be provided that allows an operator to efficiently place the component supply unit in the placement device when a transport robot acquires a component supply unit from a placement device and transports it to a component mounting device.

In the component mounting system according to the first aspect, the control device is preferably configured to create a setup list such that the setup list is arranged in order of the start time of use of the component supply units. With this configuration, the worker can easily recognize the component supply unit with the earliest start time of use (the component supply unit with the highest priority) from the setup list. As a result, the worker can perform placement work on the placement device in order from the component supply unit with the earliest start time of use (the component supply unit with the highest priority).

In the component mounting system according to the first aspect, the placement device is preferably configured to detect whether the component supply unit has been placed at a position specified by the setup list, and, if it detects that the component supply unit has been placed at an incorrect position other than the position specified by the setup list, to notify the worker to place the component supply unit at the correct position specified by the setup list. With this configuration, if the worker places the component supply unit in an incorrect position, the worker can easily recognize that the component supply unit has been placed in an incorrect position, and can easily reposition the component supply unit that has been placed in an incorrect position to the correct position.

In the component mounting system according to the first aspect, the control device is preferably configured to display the setup list on the display unit. With this configuration, the worker can easily check the setup list displayed on the display unit.

In this case, preferably, the display unit includes at least one of an area display unit provided in the area where the placement device is installed, a mobile terminal display unit provided on a mobile terminal carried by the worker, and a placement device display unit provided on the placement device. With this configuration, when the display unit is an area display unit, if there are multiple workers in the area, the multiple workers can easily check the setup list. Also, when the display unit is a mobile terminal display unit, a worker carrying a mobile terminal can easily check the setup list at the desired timing. Also, when the display unit is a placement device display unit, a worker can easily check the setup list in the vicinity of the placement device where the actual work is performed.

In the component mounting system according to the second aspect , the transport robot has a plurality of slots in which the component supply units are arranged, and the control device is configured to create a setup list so that, when a setup change is performed to switch the type of board to be produced from the current type to the next type, an empty slot for retrieving the component supply units can be provided among the plurality of slots of the transport robot. With this configuration, the transport robot can retrieve the component supply units arranged in the component mounting device to the empty slots, while replenishing the component supply units arranged in the slots other than the empty slots to the component mounting device. As a result, the transport robot can be used more efficiently than when the transport robot only retrieves the component supply units arranged in the component mounting device or only replenishing the component supply units to the component mounting device.

In the component mounting system according to the third aspect, the transport robot has a plurality of slots in which the component supply units are arranged, and the control device is configured to create a setup list so that, when a setup change is performed to switch the type of board to be produced from a current type to a next type, an empty slot for retrieving the component supply units can be provided among the plurality of slots of the transport robot. The control device is also configured to divide the setup list so that an empty slot can be provided. With this configuration, a setup list that allows an empty slot to be provided can be easily created by dividing the setup list. As a result, the transport robot can be easily and efficiently used.

In the configuration in which the setup list is divided so that the empty slots can be provided, preferably, the control device is configured to divide the setup list so that the transport robot can retrieve the component supply unit arranged in the component mounting device to an empty slot, and slide the multiple slots to supply the component supply unit arranged in the slot to the component mounting device. With this configuration, the transport robot can retrieve the component supply unit arranged in the component mounting device and supply the component supply unit to the component mounting device by simply sliding the multiple slots without moving the entire transport robot. As a result, unlike the case in which the transport robot retrieves the component supply unit arranged in the component mounting device and supplies the component supply unit to the component mounting device while moving the entire transport robot, it is not necessary to position the transport robot with respect to the component mounting device many times. This makes it easy to retrieve the component supply unit arranged in the component mounting device and supply the component supply unit to the component mounting device by the transport robot.

In the component mounting system according to the fourth aspect, the control device is configured to divide the setup list so that the setup list is divided into a plurality of supply groups when replenishing the component supply unit due to a component shortage. With this configuration, since the setup list is divided into a plurality of supply groups, the component supply unit can be transported by the transport robot at a timing that is more in line with the timing of component shortage of each component supply unit included in the supply group than when the setup list is not divided into a plurality of supply groups. As a result, it is possible to prevent the transport robot from waiting for the component supply unit to run out of components (stop time) due to the timing of the transport robot's transport of the component supply unit not matching the timing of the component supply unit running out of components. This makes it possible to prevent a decrease in the operation rate of the transport robot.

In this case, the control device is preferably configured to divide the setup list so that, among the part supply units in the setup list, the part supply units whose usage start time falls within a predetermined time are grouped together. With this configuration, it is only necessary to group the part supply units whose usage start time falls within a predetermined time, so that the setup list can be easily divided into multiple supply groups.

In the configuration for dividing the setup list so that the setup list is divided into a plurality of supply groups, the control device is preferably configured to divide the setup list so that, among the component supply units in the setup list, the component supply units whose interval between the use start times of the component supply units is within a range shorter than the time it takes for the transport robot to transport the component supply unit and return to the placement device are grouped into one group. With this configuration, supply groups can be created in which the interval between the use start times of the component supply units is within the range of the time it takes for the transport robot to transport the component supply unit and return to the placement device, so that the setup list can be divided into supply groups that can efficiently utilize the transport robot.

In the component mounting system according to the fifth aspect, the control device is configured to create a setup list by combining the component supply units to be transported to the multiple component mounting devices when the transport robot can transport the component supply units to the multiple component mounting devices. With this configuration, the component supply units of the multiple component mounting devices can be transported at once. As a result, the movement of the transport robot can be reduced compared to the case where the component supply units are transported separately to the multiple component mounting devices.

In this case, the control device is preferably configured to check whether there is an overlap in the placement positions on the placement device of the component supply units of the multiple component mounting devices based on the priority order, and if there is no overlap, to create a setup list by combining the component supply units transported to the multiple component mounting devices. With this configuration, it is possible to check whether placement positions on the placement device of the component supply units transported to the multiple component mounting devices can be secured, and if secured, to create a setup list by combining the component supply units transported to the multiple component mounting devices.

In the above-mentioned configuration for creating a setup list by combining component supply units transported to multiple component mounting devices, the control device is preferably configured to check whether there is an overlap in the placement positions of the component supply units of the multiple component mounting devices in the placement device based on the priority order, and if there is an overlap, to offset the placement position in the placement device of the component supply unit of the component mounting device with the lower priority order, and if there is no overlap, to create a setup list by combining the component supply units transported to multiple component mounting devices. With this configuration, the offsetting of the placement position in the placement device of the component supply unit can increase the possibility of creating a setup list that combines component supply units transported to multiple component mounting devices. As a result, it is easier to create a setup list that combines component supply units transported to multiple component mounting devices.

In the above-mentioned configuration in which a setup list is created by combining component supply units transported to multiple component mounting devices, the priority is preferably set based on the usage start time of the component supply unit, the number of component supply units to be transported, or the distance from the placement device to the component mounting device. By configuring in this way, the priority can be appropriately set based on the usage start time of the component supply unit related to urgency, the number of component supply units to be transported related to the amount of work, or the distance from the placement device to the component mounting device related to the transport time.

In the component mounting system according to the sixth aspect, the control device is configured to, when the placement of the component supply unit in the placement device is not in time for the transfer start time of the transport robot, check whether the component supply unit can be placed in a second placement device different from the first placement device that is the placement device specified in the setup list, and, when the component supply unit can be placed in the second placement device, change the setup list to notify the operator that the component supply unit will be placed in the second placement device. With this configuration, when the placement of the component supply unit in the first placement device is not in time, the component supply unit can be placed in the second placement device to be transferred by another transport robot. As a result, the component supply unit that was placed in the second placement device because it was not in time for placement in the first placement device can be quickly transferred by another transport robot.

In this case, the control device is preferably configured to notify the worker to transport the component supply unit if it is not possible to place the component supply unit on the second placement device. This configuration allows the worker to transport the component supply unit that was not placed on the first placement device in time, thereby preventing the component mounting device from stopping due to the component supply unit not being transported in time.

In order to achieve the above object, a component mounting method according to a seventh aspect of the present invention is a component mounting method for a component mounting system including a component mounting device that mounts components on a board using a component supply unit, a transport robot that transports the component supply unit to the component mounting device, and a placement device in which a plurality of component supply units transported by the transport robot are arranged, the method including, when acquiring a component supply unit from the placement device by the transport robot and transporting it to the component mounting device, a step of creating a setup list including information representing a placement position in the placement device of the component supply unit to be transported, and a step of notifying an operator of the created setup list, Each of the mounting device, the transport robot, and the placement device has a plurality of component supply unit placement sections in which the component supply units are placed, and the plurality of component supply unit placement sections of each of the component mounting device, the transport robot, and the placement device are configured to be able to place the component supply units in corresponding component supply unit placement sections , and the step of creating the setup list includes a step of creating the setup list so that the positions of the component supply unit placement sections in which the component supply units are placed in the placement device correspond to the positions of the component supply unit placement sections in which the component supply units are placed in the transport robot, and the positions of the component supply unit placement sections in which the component supply units are placed in the component mounting device.

In a component mounting method according to a seventh aspect of the present invention, when a transport robot acquires a component supply unit from a placement device and transports it to a component mounting device, the method includes the steps of creating a setup list including information indicating a placement position of the component supply unit to be transported in the placement device, and notifying an operator of the created setup list. This allows the setup list to clearly indicate the placement position of the component supply unit in the placement device to the operator. As a result, it is possible to prevent the operator from making a mistake in placing the component supply unit in the placement device. This provides a component mounting method that allows an operator to efficiently place the component supply unit in the placement device when a transport robot acquires a component supply unit from a placement device and transports it to a component mounting device.

Then, the worker W performs the work of placing the completed component supply unit 60 with the reel R attached in a predetermined slot 20b of the placement device 20. Then, the transport robot 40 acquires the component supply unit 60 placed by the worker W in the predetermined slot 20b of the placement device 20 (see FIG. 3(A)), and transports and places the acquired component supply unit 60 to the predetermined slot 13b of the component mounting device 13 (see FIG. 3(B)).

In addition, the worker W collects the used component supply unit 60 from a specified slot of the return device 30 and places the collected component supply unit 60 on the work desk 102. The worker W then removes the used reel R from the main body 60a of the component supply unit 60 at the work desk 102.

A display unit 103 is also provided in the work area AR2. The display unit 103 is a monitor such as an LCD monitor. The display unit 103 is provided in a position where it can be seen by one or more workers W present in the work area AR2. The worker W also carries a mobile terminal 104. The mobile terminal 104 is provided with a display unit 104a. The display unit 104a is a monitor such as an LCD monitor. The display unit 103 is an example of an "area display unit" as claimed. The display unit 104a is also an example of a "mobile terminal display unit" as claimed.

(Configuration regarding setup in work area)
Next, a configuration related to the arrangement work (setup work) of the component supply unit 60 on the arrangement device 20 by the worker W in the work area AR2 will be described with reference to FIGS.

Here, in this embodiment, as shown in FIG. 5, when the transport robot 40 acquires the component supply unit 60 from the placement device 20 and transports it to the component mounting device 13, the production management device 53 is configured to create a setup list L2 including information indicating the placement position of the component supply unit 60 to be transported in the placement device 20, and to notify the worker W of the created setup list L2. Specifically, in this embodiment, the production management device 53 is configured to display the setup list L2 on the display unit. More specifically, the production management device 53 is configured to display the setup list L2 on the display unit 103 of the work area AR2, the display unit 104a of the mobile terminal 104, and the display unit 20f of the placement device 20. For example, the production management device 53 is configured to display the setup list L2 on the display unit 103, and to display the setup list L2 on the display unit 104a of the mobile terminal 104 and the display unit 20f of the placement device 20 in response to a request from the worker W.

The production management device 53 is configured to create a requested parts list L1 for each component mounting device 13 in the mounting area AR1, and to create a setup list L2 for each component mounting device 13 in the mounting area AR1 based on the created requested parts list L1. Note that FIG. 5 shows the requested parts list L1 and setup list L2 for the first setup performed when the component supply unit 60 is not placed in the component mounting device 13.

The requested parts list L1 indicates which parts are required at which positions on which component mounting devices 13 and by what time. Specifically, the requested parts list L1 includes information indicating the type of parts required by the component mounting device 13, information indicating the position of the component mounting device 13 that requests the parts, information indicating the location (position of slot 13b) of the component supply unit 60 in the component mounting device 13 that requests the parts, and information indicating the time (use start time) when the parts are required by the component mounting device 13. In the example shown in FIG. 5, for example, it is indicated that a part of type "A" is required by 9:00 at the position of slot 13b "1" of the component mounting device 13 at the position "Mch001-A".

The setup list L2 indicates which parts are to be attached to which part supply unit 60, which position on which placement device 20 they are required at, and by what time, as well as the placement status of the part supply unit 60 on the placement device 20. Specifically, the setup list L2 includes information indicating the type of part requested by the component mounting device 13, information indicating the ID of the part supply unit 60 corresponding to the type of part, information indicating the placement device 20 that places the part supply unit 60, information indicating the placement position of the part supply unit 60 in the placement device 20 (position of slot 20b), information indicating the deadline time for the part supply unit 60 to place the part on the placement device 20, and information indicating the placement status of the part supply unit 60 on the placement device 20. In the example shown in Figure 5, for example, it is indicated that a part of type "A" is attached to a part supply unit 60 with an ID of "FEEDER-11A" and is required at slot 20b position "1" of placement device 20 with "CART001" by 8:40, and that the part supply unit 60 has not yet been placed on the placement device 20 by "Not yet".

In addition, in this embodiment, the production management device 53 is configured to create the setup list L2 so that the setup list L2 is arranged in the order of the start time of use of the part supply units 60. Specifically, the production management device 53 is configured to create the setup list L2 so that the part supply units 60 with the earliest start time of use are arranged in the upper part of the setup list L2. For example, when there are three part supply units 60 with start times of use (required times) of "9:00", "9:10", and "9:20", the production management device 53 creates the setup list L2 so that the part supply units 60 with the start time of use of "9:00", the part supply units 60 with the start time of use of "9:10", and the part supply units 60 with the start time of use of "9:20" are arranged from the top to the bottom of the setup list L2 in this order.

In addition, in this embodiment, the production management device 53 is configured to create the setup list L2 so that the position (position of slot 20b) at which the component supply unit 60 is placed in the placement device 20 corresponds to the position (position of slot 13b) at which the component supply unit 60 is placed in the component mounting device 13. For example, in the example shown in FIG. 5, the production management device 53 creates the setup list L2 so that the component supply unit 60 is placed in the slots 20b of the placement device 20 at "1", "2", "5", "7" and "10" since the component supply unit 60 is placed in the slots 13b of "1", "2", "5", "7" and "10" of the component mounting device 13. In this case, the transport robot 40 acquires the component supply unit 60 placed in the slots 20b of "1", "2", "5", "7" and "10" of the placement device 20 into the slots 40c of "1", "2", "5", "7" and "10". Then, the transport robot 40 transports and places the acquired component supply units 60 in the slots 13 b of the component mounting device 13 , numbered “1”, “2”, “5”, “7”, and “10”.

In addition, in this embodiment, the placement device 20 can detect whether the component supply unit 60 has been placed at the position (slot 20b) specified by the setup list L2. Specifically, when the component supply unit 60 is placed in the slot 20b, the placement device 20 is configured to acquire the ID of the component supply unit 60 placed in the slot 20b by the component supply unit communication unit 20h. The placement device 20 is also configured to acquire information representing the position of the slot 20b in the setup list L2 based on the acquired ID of the component supply unit 60. The placement device 20 is then configured to detect whether the component supply unit 60 has been placed at the position specified by the setup list L2 by detecting whether the acquired information representing the position of the slot 20b in the setup list L2 matches the information representing the position of the slot 20b that was actually placed.

As shown in FIG. 6, when the production management device 53 detects that the part supply unit 60 has been placed in the position (slot 20b) specified by the setup list L2 in the placement device 20, it is configured to change the placement status item of the setup list L2 displayed on the display unit 103, etc. from "Not yet" to "Completed."

7, in this embodiment, when the placement device 20 detects that the component supply unit 60 has been placed in an incorrect position (slot 20b) other than the position specified by the setup list L2, the placement device 20 is configured to notify the worker W to place the component supply unit 60 in the correct position (slot 20b) specified by the setup list L2. For example, the placement device 20 is configured to notify the worker W by displaying information on the display unit 103, 104a or 20f.

In addition, the placement device 20 is configured to notify the worker W of the position (slot 20b) specified by the setup list L2 by the lighting unit 20e when the worker W places the component supply unit 60 in the slot 20b of the placement device 20. Specifically, the placement device 20 is configured to obtain the ID of the component supply unit 60 based on the read barcode when the worker W reads the barcode of the component supply unit 60 by the reading unit 20g when placing the component supply unit 60 in the slot 20b. In addition, the placement device 20 is configured to obtain information indicating the position of the slot 20b in the setup list L2 based on the obtained ID of the component supply unit 60. The placement device 20 is configured to notify the worker W of the position (slot 20b) specified by the setup list L2 by turning on the lighting unit 20e at the position corresponding to the information indicating the position of the slot 20b in the acquired setup list L2.

Here, referring to Figure 8, the control processing for the initial setup is explained based on a sequence diagram.

As shown in FIG. 8, first, in step S1, the production management device 53 identifies the type of board S to be produced. Then, in step S2, the production management device 53 acquires the planned production start time. Then, in step S3, the production management device 53 requests a setup list from the line management device 51. Then, in step S4, the line management device 51 notifies the production management device 53 of the setup list.

Then, in step S5, the production management device 53 creates a requested parts list L1 for each component mounting device 13 based on the setup list obtained from the line management device 51. Then, in step S6, the production management device 53 creates a setup list L2 for each component mounting device 13 based on the requested parts list L1 for each component mounting device 13. Then, in step S7, the production management device 53 notifies the display unit 103, etc. of the created setup list L2. Then, in step S8, the setup list L2 is displayed on the display unit 103, etc. Then, based on the setup list L2 displayed on the display unit 103, etc., the worker W performs the placement work of the component supply unit 60 on the placement device 20.

Then, when the worker W completes the placement work of the component supply unit 60 on the placement device 20, in step S9, the production management device 53 recognizes that the setup work on the placement device 20 has been completed. For example, based on a work completion signal from the placement device 20, the production management device 53 recognizes that the setup work on the placement device 20 has been completed. Then, in step S10, the production management device 53 instructs the transport robot 40 to transport the component supply unit 60 that has been placed on the placement device 20.

Then, in step S11, the transport robot 40 moves to the placement device 20 and acquires the component supply unit 60 from the placement device 20. Then, in step S12, the transport robot 40 moves to the component mounting device 13 and supplies (attaches) the component supply unit 60 to the component mounting device 13. This completes the initial setup.

<In case of changeover>
9 and 10, in this embodiment, the production management device 53 is configured to create the setup list L2 so that, when a setup change is performed to switch the type of the board S to be produced from the current type to the next type, an empty slot 40c for retrieving the component supply unit 60 can be provided among the multiple slots 40c of the transport robot 40. In other words, the production management device 53 is configured to create the setup list L2 so that, when a setup change is performed to switch the type of the board S to be produced from the current type to the next type, an empty slot 20b for providing the empty slot 40c in the transport robot 40 is provided among the multiple slots 20b of the placement device 20.

Specifically, in this embodiment, the production management device 53 is configured to divide the setup list L2 so that an empty slot 40c can be provided. More specifically, the production management device 53 is configured to divide the setup list L2 so that the transport robot 40 can collect the component supply unit 60 arranged in the component mounting device 13 to the empty slot 40c, and slide the multiple slots 40c to supply the component supply unit 60 arranged in the slot 40c to the component mounting device 13. For example, the production management device 53 is configured to divide the setup list L2 so that an empty slot 40c can be provided every other slot.

Furthermore, when the production management device 53 divides the setup list L2, it is configured to specify different placement devices 20 in the divided setup list L2. Furthermore, when the production management device 53 divides the setup list L2, it is configured to bring forward the work deadline in the divided setup list L2. This makes it possible to prevent delays in the transportation of the component supply unit 60 even if the number of transports by the transport robot 40 increases due to the division of the setup list L2.

In the example shown in FIG. 9, one setup list L2 is divided into two setup lists L2a and L2b. In the setup list L2 before division, the slots 20b "1 to 10" of the placement device 20 of "CART001" are specified as the placement positions of the component supply unit 60. In the setup list L2a after division, the odd-numbered slots 20b "1, 3, 5, 7, 9" of the placement device 20 of "CART001" are specified as the placement positions of the component supply unit 60. In the setup list L2b after division, the even-numbered slots 20b "2, 4, 6, 8, 10" of the placement device 20 of "CART002", which is different from "CART001", are specified as the placement positions of the component supply unit 60. This makes it possible to provide an empty slot 40c every other slot in the transport robot 40.

In addition, in the post-split setup list L2a, the work deadline is specified as "8:20," which is earlier than "8:40" in the pre-split setup list L2.

In this case, as shown in FIG. 10, the transport robot 40 acquires the component supply units 60 for the slots 40c "1, 3, 5, 7, 9" from the placement device 20 in which the component supply units 60 to be used in the production of the next type of board S are placed in the slots 20b "1, 3, 5, 7, 9" based on the setup list L2a. At this time, the slots 40c "2, 4, 6, 8, 10" become vacant slots 40c. Then, the transport robot 40 moves to the component mounting device 13 with the component supply units 60 to be used in the production of the next type of board S placed in the slots 40c "1, 3, 5, 7, 9" and is positioned relative to the component mounting device 13. In the component mounting device 13, the component supply units 60 used in the production of the current type of board S are placed in the slots 13b "1 to 10".

Then, the transport robot 40 retrieves the component supply units 60 arranged in the slots 13b of the component mounting device 13 of "1, 3, 5, 7, 9" by the insertion/removal unit 40f to the empty slots 40c of "2, 4, 6, 8, 10". Then, the transport robot 40 slides the multiple slots 40c horizontally by one slot by the slide unit 40g. Then, the transport robot 40 supplies the component supply units 60 arranged in the slots 40c of "1, 3, 5, 7, 9" to the slots 13b of the component mounting device 13 of "1, 3, 5, 7, 9" by the insertion/removal unit 40f. This replaces the component supply units 60 in the slots 13b of "1, 3, 5, 7, 9" of the component mounting device 13. Although detailed explanations are omitted, the operation of the transport robot 40 based on the setup list L2b is also similar. As a result, the component supply units 60 in the slots 13b of the component mounting device 13 are replaced.

Here, the control process in the case of changeover will be described based on a sequence diagram with reference to Figure 11. Note that the same processes as those shown in Figure 8 are denoted by the same reference numerals, and detailed descriptions thereof will be omitted.

As shown in Figure 11, first, steps S1 to S5 are processed in the same manner as the control process shown in Figure 8. Then, in step S6a, the production management device 53 creates a setup list L2 for each component mounting device 13 based on the required parts list L1 for each component mounting device 13. At this time, if the setup list L2 can be divided, the production management device 53 divides the setup list L2 so that an empty slot 40c can be provided.

Then, steps S7 to S11 are performed in the same manner as the control process shown in Fig. 8. Then, in step S12a, the transport robot 40 moves to the component mounting device 13, retrieves the component supply unit 60 from the component mounting device 13 to an empty slot 40c, and slides the multiple slots 40c to replenish (attach) the component supply unit 60 to the component mounting device 13 from the slots 40c other than the empty slot 40c. This allows a changeover.

<In case of out-of-stock parts>
In this embodiment, as shown in Fig. 12, the production management device 53 is configured to divide the setup list L2 so that the setup list L2 is divided into a plurality of supply groups when replenishing the component supply units 60 due to component shortage. For example, the production management device 53 is configured to divide the setup list L2 so that the component supply units 60 whose use start times are within a predetermined time (for example, within 5 minutes) are grouped into one group. For example, the production management device 53 is configured to divide the setup list L2 so that the component supply units 60 whose use start times are within a range shorter than the time it takes for the transport robot 40 to transport the component supply units 60 and return to the placement device 20 are grouped into one group.

In the example shown in FIG. 12, five parts, "Parts_A", "Parts_B", "Parts_C", "Parts_D", and "Parts_E", are likely to run out of stock in the component mounting device 13 of "Mch001-A", so one requested parts list L1 is created, including the five parts, "Parts_A", "Parts_B", "Parts_C", "Parts_D", and "Parts_E". Then, based on the requested parts list L1, one setup list L2 is created, including the five parts, "Parts_A", "Parts_B", "Parts_C", "Parts_D", and "Parts_E", but the setup list L2 is divided into two setup lists L2c and L2d so as to be divided into two supply groups.

In the setup list L2c after division, three of the above five parts are included: "Parts_A", "Parts_B", and "Parts_C". In addition, in the setup list L2d after division, two of the above five parts are included: "Parts_D" and "Parts_E".

In this case, as shown in Fig. 10, the transport robot 40 acquires three component supply units 60 from the placement device 20 in which the three component supply units 60 holding the three components "Parts_A", "Parts_B", and "Parts_C" are arranged based on the setup list L2c. Then, with the three component supply units 60 arranged, the transport robot 40 moves to the component mounting device 13 and supplies the three component supply units 60 to the component mounting device 13.

At another timing, the transport robot 40 acquires two component supply units 60 from the placement device 20 in which the two component supply units 60 holding the two components "Parts_D" and "Parts_E" are arranged based on the setup list L2d. Then, with the two component supply units 60 arranged, the transport robot 40 moves to the component mounting device 13 and supplies the two component supply units 60 to the component mounting device 13.

<When combining multiple component mounting devices>
13, in this embodiment, when the transport robot 40 can transport the component supply units 60 to the multiple component mounting devices 13, the production management device 53 is configured to create a setup list L2 by combining the component supply units 60 to be transported to the multiple component mounting devices 13. Specifically, the production management device 53 is configured to create a required parts list L1 for each of the multiple component mounting devices 13, and when the created required parts lists L1 for each of the multiple component mounting devices 13 can be combined, to create a setup list L2 by combining the component supply units 60 to be transported to the multiple component mounting devices 13.

Specifically, in this embodiment, the production management device 53 is configured to check whether there is any overlap in the placement positions of the component supply units 60 of the multiple component mounting devices 13 in the placement device 20 based on the priority order, and if there is no overlap, to create a setup list L2 by combining the component supply units 60 to be transported to the multiple component mounting devices 13. The production management device 53 is also configured to continue repeatedly checking whether there is any overlap while changing the component mounting device 13 to be checked based on the priority order, until there are no more combinations of component supply units 60 of the multiple component mounting devices 13.

In this embodiment, the priority is set based on the time when the component supply unit 60 starts being used, the number of component supply units 60 to be transported, or the distance from the placement device 20 to the component mounting device 13. For example, the priority is set to be higher for a component mounting device 13 that starts using its component supply unit 60 earlier. Also, for example, the priority is set to be higher for a component mounting device 13 that has a greater number of component supply units 60 to be transported. Also, for example, the priority is set to be higher for a component mounting device 13 that is closer to the placement device 20.

In the example shown in FIG. 13, the position (position of slot 13b) of the component supply unit 60 in the component mounting device 13 of "Mch001-A" is "1, 2, 5, 7, 10." That is, the position (position of slot 20b) of the component supply unit 60 in the placement device 20 of the component mounting device 13 of "Mch001-A" is "1, 2, 5, 7, 10." Also, the position (position of slot 13b) of the component supply unit 60 in the component mounting device 13 of "Mch002-A" is "4, 6, 9." That is, the position (position of slot 20b) of the component supply unit 60 in the placement device 20 of the component mounting device 13 of "Mch002-A" is "4, 6, 9."

And since the positions "1, 2, 5, 7, 10" of the component mounting device 13 of "Mch001-A" do not overlap with the positions "4, 6, 9" of the component mounting device 13 of "Mch002-A", the setup list L2 is created by combining the component supply units 60 to be transported to the two component mounting devices 13 of "Mch001-A" and "Mch002-A". In this case, the transport robot 40 acquires eight component supply units 60 from the placement device 20 in which the eight component supply units 60 for the two component mounting devices 13 of "Mch001-A" and "Mch002-A" are arranged. Then, the transport robot 40 transports the eight component supply units 60 for the two component mounting devices 13 of "Mch001-A" and "Mch002-A" in one transport.

In this embodiment, as shown in FIG. 14, the production management device 53 is configured to check whether there is an overlap in the placement positions of the component supply units 60 of the multiple component mounting devices 13 on the placement device 20 based on the priority order, and if there is an overlap, to offset the placement positions of the component supply units 60 of the component mounting device 13 with the lower priority order on the placement device 20, and if there is no overlap, to combine the component supply units 60 transported to the multiple component mounting devices 13 to create the setup list L2. Specifically, the production management device 53 is configured to offset the placement positions of the component supply units 60 of the component mounting device 13 with the lower priority order on the placement device 20 by one slot when there is an overlap, and to combine the component supply units 60 transported to the multiple component mounting devices 13 to create the setup list L2 when there is no overlap, and not to combine the component supply units 60 transported to the multiple component mounting devices 13 to create the setup list L2 when there is no overlap even after offsetting by one slot.

In the example shown in FIG. 14, the position (position of slot 13b) of the component supply unit 60 in the component mounting device 13 of "Mch001-A" is "1, 2, 5, 7, 10." That is, the position (position of slot 20b) of the component supply unit 60 in the placement device 20 of the component mounting device 13 of "Mch001-A" is "1, 2, 5, 7, 10." Also, the position (position of slot 13b) of the component supply unit 60 in the component mounting device 13 of "Mch002-A" is "5, 7, 10." That is, the position (position of slot 20b) of the component supply unit 60 in the placement device 20 of the component mounting device 13 of "Mch002-A" is "5, 7, 10."

And because the positions "1, 2, 5, 7, 10" of the component mounting device 13 of "Mch001-A" overlap with the position "5, 7, 10" of the component mounting device 13 of "Mch002-A", the position "5, 7, 10" of the component mounting device 13 of "Mch002-A", which has the lower priority, is offset by one slot. As a result, the placement position (position of slot 20b) of the component supply unit 60 in the placement device 20 of the component mounting device 13 of "Mch002-A" is changed to "4, 6, 9".

And since the positions "1, 2, 5, 7, 10" of the component mounting device 13 "Mch001-A" and the positions "4, 6, 9" of the component mounting device 13 "Mch002-A" no longer overlap, the setup list L2 is created by combining the component supply units 60 to be transported to the two component mounting devices 13 "Mch001-A" and "Mch002-A". In this case, the transport robot 40 acquires eight component supply units 60 from the placement device 20 in which the eight component supply units 60 for the two component mounting devices 13 "Mch001-A" and "Mch002-A" are arranged. Then, the transport robot 40 transports the eight component supply units 60 for the two component mounting devices 13 "Mch001-A" and "Mch002-A" in one transport. In addition, when the transport robot 40 supplies the component supply unit 60 to the offset component mounting device 13 of "Mch002-A", it uses the slide unit 40g to slide the multiple slots 40c horizontally by one slot and supplies the component supply unit 60.

<If you cannot make it in time for the start of transport>
In this embodiment, as shown in FIG. 15, when the placement of the part supply unit 60 on the placement device 20 is not in time for the transfer start time of the transfer robot 40, the production management device 53 is configured to check whether the part supply unit 60 can be placed on the second placement device 22 (the placement device 20 of "CART002") different from the first placement device 21 (the placement device 20 of "CART001"), which is the placement device 20 specified in the setup list L2, and to change the setup list L2 so as to notify the worker W that the part supply unit 60 will be placed on the second placement device 22 if the part supply unit 60 can be placed on the second placement device 22. Specifically, the production management device 53 is configured to notify the worker W that the part supply unit 60 will be placed on the second placement device 22 by changing the display of the item of the placement device 20 in the setup list L2 displayed on the display unit 103 or the like from the first placement device 21 to the second placement device 22.

In addition, in this embodiment, as shown in Fig. 16, when the part supply unit 60 cannot be placed on the second placement device 22, the production management device 53 is configured to notify the worker W to transport the part supply unit 60. Specifically, the production management device 53 is configured to notify the worker W to transport the part supply unit 60 by displaying information on the display unit 103 or the like.

Here, referring to Figure 17, the control process in the case where the transport start time is not met will be explained based on a flowchart.

As shown in FIG. 17, first, in step S21, the production management device 53 determines whether or not all of the component supply units 60 to be transported have been placed on the placement device 20. If it is determined that all of the component supply units 60 to be transported have been placed on the placement device 20, the process proceeds to step S22. Then, in step S22, the production management device 53 issues a transport instruction to the transport robot 40.

Also, if it is determined in step S21 that all of the component supply units 60 to be transported have not been placed on the placement device 20, the process proceeds to step S23. Then, in step S23, the production management device 53 determines whether the transport start time of the transport robot 40 has passed. If it is determined that the transport start time of the transport robot 40 has not passed, the process proceeds to step S21, and the processing of step S21 is repeated. Also, if it is determined that the transport start time of the transport robot 40 has passed, the process proceeds to step S24.

Then, in step S24, the production management device 53 determines whether it is acceptable for the next transport of the transport robot 40 that started transport at the transport start time. If it is determined that it is acceptable for the next transport of the transport robot 40, after the transport robot 40 returns, the component supply unit 60 that did not make it in time for the transport start time is transported by the returned transport robot 40. In this case, the component supply unit 60 that did not make it in time for the transport start time is left in its original placement device 20 (in FIG. 15, the placement device 20 of "CART001").

Also, in step S24, if it is determined that the next transport of the transport robot 40 is not suitable, the process proceeds to step S25. Then, in step S25, the production management device 53 determines whether or not the component supply unit 60 can be placed in a placement device 20 (second placement device 22) different from the original placement device 20 (first placement device 21) specified in the setup list L2. If it is determined that the component supply unit 60 can be placed in the second placement device 22, the process proceeds to step S26. Then, in step S26, the production management device 53 changes the display of the placement device 20 in the setup list L2 displayed on the display unit 103, etc. from the first placement device 21 to the second placement device 22. Then, the worker W performs the task of placing the component supply unit 60 in the second placement device 22 based on the changed setup list L2.

If it is determined in step S25 that the component supply unit 60 cannot be placed on the second placement device 22, the process proceeds to step S27. Then, in step S27, the production management device 53 issues a transport instruction to the worker W to transport the component supply unit 60 by displaying the instruction on the display unit 103 or the like. Then, based on the transport instruction, the worker W transports the component supply unit 60 to the slot 13b of the component mounting device 13 that requires the component supply unit 60.

(Effects of this embodiment)
In this embodiment, the following effects can be obtained.

In this embodiment, as described above, when the transport robot 40 acquires the component supply unit 60 from the placement device 20 and transports it to the component mounting device 13, a production management device 53 is provided that creates a setup list L2 including information indicating the placement position of the component supply unit 60 to be transported in the placement device 20, and notifies the worker W of the created setup list L2. As a result, the setup list L2 can clearly indicate the placement position of the component supply unit 60 in the placement device 20 to the worker W. As a result, it is possible to prevent the worker W from making a mistake in placing the component supply unit 60 on the placement device 20. As a result, when the transport robot 40 acquires the component supply unit 60 from the placement device 20 and transports it to the component mounting device 13, the worker W can efficiently place the component supply unit 60 on the placement device 20.

In addition, in this embodiment, as described above, the production management device 53 is configured to create the setup list L2 so that the setup list L2 is arranged in the order of the start time of use of the component supply units 60. This allows the worker W to easily recognize the component supply units 60 that have an earlier start time of use (the component supply units 60 with a higher priority) from the setup list L2. As a result, the worker W can perform placement work on the placement device 20 in the order of the component supply units 60 that have an earlier start time of use (the component supply units 60 with a higher priority).

In addition, in this embodiment, as described above, the production management device 53 is configured to create the setup list L2 so that the position at which the component supply unit 60 is placed in the placement device 20 corresponds to the position at which the component supply unit 60 is placed in the component mounting device 13. This allows the worker W to place the component supply unit 60 in the placement device 20 based on the setup list L2 so that the position at which the component supply unit 60 is placed in the placement device 20 corresponds to the position at which the component supply unit 60 is placed in the component mounting device 13. As a result, the transport robot 40 can acquire the component supply unit 60 from the placement device 20 so that the position at which the component supply unit 60 is placed in the transfer robot 40 corresponds to the position at which the component supply unit 60 is placed in the component mounting device 13. In other words, the transport robot 40 can acquire the component supply unit 60 from the placement device 20 so that the component supply unit 60 can be easily supplied to the component mounting device 13. As a result, the transport robot 40 can more efficiently supply the component supply unit 60 to the component mounting device 13 than when the position at which the component supply unit 60 is located on the transport robot 40 does not correspond to the position at which the component supply unit 60 is located on the component mounting device 13.

In addition, in this embodiment, as described above, the placement device 20 is configured to detect whether the component supply unit 60 has been placed at a position specified by the setup list L2, and when it detects that the component supply unit 60 has been placed at an incorrect position other than the position specified by the setup list L2, to notify the worker W to place the component supply unit 60 at the correct position specified by the setup list L2. This allows the worker W to easily recognize that the component supply unit 60 has been placed at an incorrect position when the worker W places the component supply unit 60 at an incorrect position, and to easily reposition the component supply unit 60 that has been placed at the incorrect position to the correct position.

In addition, in this embodiment, as described above, the production management device 53 is configured to display the setup list L2 on the display units 103, 104a, and 20f. This allows the worker W to easily check the setup list L2 displayed on the display unit.

In addition, in this embodiment, as described above, the display units 103, 104a, and 20f include at least one of the display unit 103 provided in the work area AR2 in which the placement device 20 is provided, the display unit 104a provided in the mobile terminal 104 carried by the worker W, and the display unit 20f provided in the placement device 20. As a result, when the display unit is the display unit 103, when there are multiple workers W in the work area AR2, the multiple workers W can easily check the setup list L2. When the display unit is the display unit 104a, the worker W carrying the mobile terminal 104 can easily check the setup list L2 at the desired timing. When the display unit is the display unit 20f, the worker W can easily check the setup list L2 in the vicinity of the placement device 20 where the actual work is performed.

In addition, in this embodiment, as described above, the transport robot 40 has a plurality of slots 40c in which the component supply unit 60 is arranged. In addition, the production management device 53 is configured to create a setup list L2 so that, when a setup change is performed to switch the type of the board S to be produced from the current type to the next type, an empty slot 40c for recovering the component supply unit 60 can be provided among the plurality of slots 40c of the transport robot 40. As a result, the transport robot 40 can recover the component supply unit 60 arranged in the component mounting device 13 to the empty slot 40c, while supplying the component supply unit 60 arranged in the slot 40c other than the empty slot 40c to the component mounting device 13. As a result, the transport robot 40 can be used more efficiently than when the transport robot 40 only recovers the component supply unit 60 arranged in the component mounting device 13 or only supplies the component supply unit 60 to the component mounting device 13.

In addition, in this embodiment, as described above, the production management device 53 is configured to divide the setup list L2 so that an empty slot 40c can be provided. This makes it possible to easily create a setup list L2 that can provide an empty slot 40c by dividing the setup list L2. As a result, the transport robot 40 can be used easily and efficiently.

In addition, in this embodiment, as described above, the production management device 53 is configured to divide the setup list L2 so that the transport robot 40 can recover the component supply unit 60 arranged in the component mounting device 13 to an empty slot 40c, and can slide the multiple slots 40c to supply the component supply unit 60 arranged in the slot 40c to the component mounting device 13. As a result, the transport robot 40 can recover the component supply unit 60 arranged in the component mounting device 13 and supply the component supply unit 60 to the component mounting device 13 by simply sliding the multiple slots 40c without moving the entire transport robot 40. As a result, unlike the case where the transport robot 40 recovers the component supply unit 60 arranged in the component mounting device 13 and supplies the component supply unit 60 to the component mounting device 13 while moving the entire transport robot 40, there is no need to position the transport robot 40 with respect to the component mounting device 13 many times. This allows the transport robot 40 to easily retrieve the component supply units 60 arranged on the component mounting device 13 and replenish the component supply units 60 to the component mounting device 13 .

In addition, in this embodiment, as described above, the production management device 53 is configured to divide the setup list L2 so that the setup list L2 is divided into multiple supply groups when replenishing the part supply unit 60 due to a part shortage. As a result, since the setup list L2 is divided into multiple supply groups, the part supply unit 60 can be transported by the transport robot 40 at a timing that is more in line with the timing of the part shortage of each part supply unit 60 included in the supply group than when the setup list L2 is not divided into multiple supply groups. As a result, it is possible to suppress the occurrence of a time (stop time) during which the transport robot 40 waits for the part supply unit 60 to run out of parts due to the transport of the part supply unit 60 by the transport robot 40 not matching the timing of the part supply unit 60 to run out of parts. This makes it possible to suppress a decrease in the operating rate of the transport robot 40.

In this embodiment, as described above, the production management device 53 is configured to divide the setup list L2 such that, among the part supply units 60 in the setup list L2, the part supply units 60 whose use start time is within a predetermined time are grouped into one group. This allows the setup list L2 to be easily divided into multiple supply groups, since it is only necessary to group the part supply units 60 whose use start time is within a predetermined time into one group.

In addition, in this embodiment, as described above, the production management device 53 is configured to divide the setup list L2 so that, among the component supply units 60 in the setup list L2, the component supply units 60 whose interval between the use start times of the component supply units 60 is within a range shorter than the time it takes for the transport robot 40 to transport the component supply units 60 and return to the placement device 20 are grouped together. This makes it possible to create supply groups whose interval between the use start times of the component supply units 60 is within the range of the time it takes for the transport robot 40 to transport the component supply units 60 and return to the placement device 20, so that the setup list L2 can be divided into supply groups that can efficiently use the transport robot 40.

In addition, in this embodiment, as described above, the production management device 53 is configured to create a setup list L2 by combining the component supply units 60 to be transported to multiple component mounting devices 13 when the transport robot 40 can transport the component supply units 60 to multiple component mounting devices 13. This allows the component supply units 60 of multiple component mounting devices 13 to be transported at once. As a result, the movement of the transport robot 40 can be reduced compared to the case where the component supply units 60 are transported separately to multiple component mounting devices 13.

In addition, in this embodiment, as described above, the production management device 53 is configured to check whether there is an overlap in the placement positions on the placement device 20 of the component supply units 60 of the multiple component mounting devices 13 based on the priority order, and if there is no overlap, to create a setup list L2 by combining the component supply units 60 to be transported to the multiple component mounting devices 13. This makes it possible to check whether the placement positions on the placement device 20 of the component supply units 60 to be transported to the multiple component mounting devices 13 can be secured, and if secured, to create a setup list L2 by combining the component supply units 60 to be transported to the multiple component mounting devices 13.

In addition, in this embodiment, as described above, the production management device 53 is configured to check whether there is an overlap in the placement positions of the component supply units 60 of the multiple component mounting devices 13 in the placement device 20 based on the priority order, and if there is an overlap, to offset the placement positions of the component supply units 60 of the component mounting device 13 with the lower priority order in the placement device 20, and when there is no overlap, to create a setup list L2 by combining the component supply units 60 transported to the multiple component mounting devices 13. This increases the possibility of creating a setup list L2 that combines the component supply units 60 transported to the multiple component mounting devices 13 by offsetting the placement positions of the component supply units 60 in the placement device 20. As a result, it is possible to easily create a setup list L2 that combines the component supply units 60 transported to the multiple component mounting devices 13.

In addition, in this embodiment, as described above, the priority is set based on the usage start time of the component supply unit 60, the number of component supply units 60 to be transported, or the distance from the placement device 20 to the component mounting device 13. This allows the priority to be appropriately set based on the usage start time of the component supply unit 60 regarding urgency, the number of component supply units 60 to be transported regarding the amount of work, or the distance from the placement device 20 to the component mounting device 13 regarding the transport time.

In this embodiment, as described above, the production management device 53 is configured to check whether the part supply unit 60 can be placed in the second placement device 22, which is different from the first placement device 21 that is the placement device 20 specified in the setup list L2, when the placement of the part supply unit 60 in the placement device 20 is not in time for the start of the transfer of the transport robot 40, and to change the setup list L2 so as to notify the worker W that the part supply unit 60 will be placed in the second placement device 22 if the part supply unit 60 can be placed in the second placement device 22. As a result, when the part supply unit 60 is not placed in the first placement device 21 in time, the part supply unit 60 can be placed in the second placement device 22, which is transferred by another transport robot 40. As a result, the part supply unit 60 that was placed in the second placement device 22 because the placement in the first placement device 21 was not in time can be quickly transferred by another transport robot 40.

In addition, in this embodiment, as described above, the production management device 53 is configured to notify the worker W to transport the component supply unit 60 when it is not possible to place the component supply unit 60 on the second placement device 22. This allows the worker W to transport the component supply unit 60 that was not placed on the first placement device 21 in time, thereby preventing the component mounting device 13 from stopping due to the component supply unit 60 not being transported in time.
