In the output step (S130), the production number information is outputted.

Description

  The present invention relates to a production number information generation method for generating information relating to the number of productions in a mounting line having a plurality of conveyance lanes.

  Conventionally, when switching the type of board to which components are mounted in a mounting line in which multiple component mounters are connected, all other types of boards are mounted after completing the mounting of the type of board currently being mounted. The mounting units are replaced so that components can be mounted on the mounting unit.

  However, when the setup change method is adopted, the installation line is completely stopped and the setup units of the installation units included in the implementation line are changed.

  Therefore, in synchronization with the operation of transporting the final board of the type of board currently being mounted from upstream to downstream, the setup change start signal is sequentially transmitted to the component mounting machine downstream from the position where the final board exists. The technique to do is disclosed by patent document 1. FIG.

  According to Patent Document 1, by adopting this technology, the component mounter that has received the setup change start signal can determine that the board that has been transported at that time is the final board of the type of board, It is described that the setup change can be started when the mounting of the final board is completed.

  Conventionally, there is a mounting line having two transport lanes formed by connecting a plurality of component mounters each composed of a set of mounting units arranged to face each other.

  Specifically, two transport lanes are formed by connecting a transport device that transports a substrate included in each of the plurality of mounting units provided in the mounting line.

  A technique for improving the production efficiency of a mounting line having such a plurality of conveyance lanes is also disclosed (see, for example, Patent Document 2).

  According to the technique described in Patent Document 2, synchronization is performed in which the mounting line is synchronized with substrate transportation or the like in the two transportation lanes according to whether the types of the substrates to be input to the two transportation lanes are the same or not. It is determined whether to operate in the mode or the asynchronous mode in which the substrate transportation in the two transportation lanes is performed independently. In this way, it is possible to improve the production efficiency by automatically determining the operation mode without depending on the operator.

  Here, even in the above-described mounting line having a plurality of transfer lanes, if there is a change in the type of board to be mounted with components (hereinafter, also referred to as “product type switching”), each mounting unit has a step as necessary. A replacement is made.

  For example, in a mounting line having a first transport lane and a second transport lane, one set of a plurality of sets of mounting units arranged to face each other is defined as a first mounting unit and a second mounting unit.

  In this mounting line, the same number of types of boards before switching the product type is loaded into each transfer lane, so that new types of boards after switching the product type reach the first mounting unit and the second mounting unit almost simultaneously. Assume that In this case, the operation of both the first mounting unit and the second mounting unit is stopped, and the operator starts one of the setup changes. Thereafter, when the one set-up is completed, the set-up for the other is started.

  That is, while one of the first mounting unit and the second mounting unit is being replaced, the other is left in an operation stopped state. For example, if the one set-up time is 5 minutes, both the first mounting unit and the second mounting unit are stopped for 5 minutes. This is a factor that greatly reduces the production efficiency of the component mounting board.

  In order to suppress the occurrence of such waste, it is also conceivable to arrange a plurality of operators for the setup change, for example. However, in this case, for example, in a factory where a plurality of mounting lines are arranged, it is necessary to arrange a large number of operators for setup change, which is not a realistic solution.

  In addition, for example, by switching the number of boards distributed to the first transport lane and the second transport lane of the type of board before the product type switching to either one, it is possible to switch the product type of the first mounting unit and the second mounting unit. It is also possible to improve the possibility that the corresponding setup change will not occur at the same time. However, in this case, one of the first transport lane and the second transport lane ends the production work quickly, and the other continues the production work for a long time. It is thought that it occurs.

  In consideration of the above-described conventional problems, the present invention provides a production number information generation method and a production number information generation apparatus for suppressing a decrease in production efficiency due to setup change in a mounting line having two conveyance lanes. Objective.

  In order to achieve the above object, a production number information generation method according to an aspect of the present invention is the production number of component mounting boards in a mounting line formed by connecting a plurality of sets of mounting units arranged to face each other. The production number information generation method for generating information related to the above-mentioned, wherein the set of mounting units includes a first mounting unit having a first transport device and a second mounting unit having a second transport device. And the mounting line includes a first transport lane formed by connecting the plurality of first transport devices, and a second transport lane formed by connecting the plurality of second transport devices. In the production number information generation method, the plurality of first mounting units each of which is a first type board from a first board to which a component mounting target board is a second type board. Switch to two boards The maximum setup time acquisition step for acquiring the first maximum time, which is the maximum setup time, of the setup time, which is the time required for the setup change to enable component mounting on the second board. And a first unit production time, which is a time required for component mounting per one board in the second mounting unit facing the first mounting unit corresponding to the acquired first maximum time. A unit production time acquisition step, using a value obtained by dividing the first maximum time by the first unit production time, a first production number that is the number of the first substrate to be put into the first transport lane, A generation step for generating production number information indicating a difference from a second production number that is the number of the first substrates to be put into the second transport lane; and an output step for outputting the generated production number information. Including.

  According to this method, the first mounting unit having the maximum setup time and the maximum setup time (first maximum time) are specified among the plurality of first mounting units. Further, the number of first substrates that can be mounted by the second mounting unit facing the first mounting unit within the first maximum time is calculated. Further, production number information indicating the difference between the first production number and the second production number is generated and output using the obtained number.

  By using the production number information output in this way, while the setup change requiring the maximum setup time is being executed in the first mounting unit, the component to the first board is transferred to the second mounting unit. Implementation can continue.

  In other words, the setup change timing of the first mounting unit and the setup change timing of the second mounting unit can be shifted by an amount corresponding to the difference. Further, as described above, the difference is determined by using the number of producible sheets of the second mounting unit corresponding to the maximum setup time, and thus does not become unnecessarily large.

  That is, the occurrence of an inefficient state due to an increase in the time during which only one of the two transport lanes is operating is suppressed.

  Thus, according to the production number information generation method of this aspect, it is possible to suppress a decrease in production efficiency due to setup change in a mounting line having two transport lanes.

  Further, in the production number information generation method according to one aspect of the present invention, in the generation step, (a) the second mounting unit is the first unit time by dividing the first maximum time by the first unit production time. Calculating a difference number, which is the number of the first substrates that can be mounted in one maximum time, and (b) a difference between the first production number and the second production number being equal to or greater than the difference number As described above, the first production number and the second production number may be determined, and (c) the production number information indicating the determined first production number and the second production number may be generated.

  According to this method, production number information indicating each of the first production number and the second production number is generated and output. That is, since the information directly indicating the first production number and the second production number is output, for example, an operation using the information is efficiently performed.

  Further, in the production number information generation method according to one aspect of the present invention, in the maximum setup time acquisition step, a plurality of work contents in the setup change for each of the plurality of first mounting units are specified, and the specified plurality The setup time of each of the plurality of first mounting units for each of the plurality of work contents may be calculated by referring to a setup time database that stores an individual time that is a required time for each of the work contents. .

  According to this method, for example, even when the content of the setup change of any mounting unit is changed, the setup time corresponding to the setup change can be easily calculated.

  In the production number information generation method according to an aspect of the present invention, in the output step, the production number information is output to a display device that displays information, thereby causing the display device to display the production number information. It is good.

  According to this method, for example, the operator can immediately obtain the production number information generated by the method.

  In the production number information generation method according to one aspect of the present invention, the mounting line further includes a substrate loading device for loading a substrate into each of the first transport lane and the second transport lane, and the output step. Then, by outputting the previous production number information to the substrate loading device, the first production number of the first substrates is loaded into the first transport lane, and the second production number of the first substrates It is also possible to input.

  According to this method, the loading operation of the first substrate to each transfer lane is automatically executed according to the production number information generated by the method.

  Further, in the production number information generation method according to an aspect of the present invention, in the maximum setup time acquisition step, a component mounting target board of each of the plurality of first mounting units is further changed from the second board to the third board time. The maximum setup time of the setup time, which is the time required for the setup change to make it possible to mount the component on the third board, required when switching to the third board which is the kind of board. The second maximum time is acquired, and in the unit production time acquisition step, the component per second board in the second mounting unit facing the first mounting unit corresponding to the acquired second maximum time. A second unit production time, which is a time required for mounting, is acquired, and the generation step further includes a difference between the first production number and the second production number, and the second maximum time. Using the value divided by the second unit production time, the difference between the number of the second substrate to be loaded into the first transfer lane and the number of the second substrate to be loaded into the second transfer lane is calculated. The production number information shown may be generated.

  According to this method, when the product type is switched from the second substrate to the third substrate, the difference between the previously determined first production number and second production number is considered. Thereby, the setup change timing of the first mounting unit requiring the maximum setup time and the setup change timing of the second mounting unit facing the first mounting unit can be shifted by an appropriate amount.

  The present invention can also be realized as a production number information generation apparatus that executes the production number information generation method according to any one of the above aspects.

  Further, the present invention can be realized as a program for causing a computer to execute each process included in the production number information generation method according to any one of the above aspects, and can be realized as a recording medium on which the program is recorded. it can. The program can be distributed via a transmission medium such as the Internet or a recording medium such as a DVD.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an outline of a production system 100 according to an embodiment of the present invention.

  As shown in FIG. 1, the production system 100 according to the embodiment includes a mounting line 110 that produces a component mounting board, and a control device 105 that is connected to the mounting line 110 via a communication network and controls the operation of the mounting line 110. With.

  In the present embodiment, the mounting line 110 is formed by connecting a plurality of component mounting machines 120 having two transfer devices that can transfer a substrate independently of each other. In the present embodiment, specifically, six component mounters 120 of component mounters [A] to [F] are connected.

  Moreover, the 1st conveyance lane 111 and the 2nd conveyance lane 112 are formed by connecting the conveying apparatus which each of component mounting machine [A]-[F] has between component mounting machines. Component mounting boards are produced in each of these two transport lanes.

  In addition, a display device 106 is connected to the control device 105, and various information related to the mounting line 110 is displayed on the display device 106.

  Note that the plurality of component mounters 120 included in the mounting line 110 need not be the same model. In FIG. 1, the mounting line 110 only needs to include a plurality of component mounting machines 120, and the number of the mounting lines 110 is not limited. Further, the mounting line 110 may include other types of devices necessary for component mounting, such as a printing machine and a reflow device.

  FIG. 2 is a plan view showing a main configuration of the component mounter 120 in the embodiment.

  As shown in FIG. 2, the component mounting machine 120 includes a first mounting unit 121 and a second mounting unit 122 that are arranged to face each other.

  The first mounting unit 121 includes a first transport device 131 that transports a substrate, a first head 151 that removably holds a plurality of suction nozzles, and a first component that removably holds a plurality of component cassettes that store a plurality of components. A one-component supply unit 141 and a first nozzle station 161 that holds a plurality of replacement suction nozzles are provided.

  The first head 151 sucks a component supplied from the first component supply unit 141 by a suction nozzle, and mounts the component on the board carried by the first transport device 131.

  Moreover, the 1st head 151 can replace | exchange the suction nozzle currently hold | maintained with the suction nozzle currently hold | maintained at the 1st nozzle station 161 by moving to the upper direction of the 1st nozzle station 161. FIG. In other words, automatic nozzle replacement is possible.

  Similarly to the first mounting unit 121, the second mounting unit 122 includes a second transport device 132, a second head 152, a second component supply unit 142, and a second nozzle station 162.

  Each of the first head 151 and the second head 152 is movably attached to a beam (not shown) that extends in the X-axis direction and moves in parallel in the Y-axis direction. Thereby, mounting of a plurality of components on a substrate and automatic nozzle replacement can be performed.

  A plurality of component mounters 120 having such a configuration are arranged in the X-axis direction, and adjacent first transfer devices 131 are connected to form a first transfer lane 111 (see FIG. 1). Moreover, the 2nd conveyance lane 112 is formed by connecting the adjacent 2nd conveyance apparatuses 132 mutually.

  Moreover, in this Embodiment, the 1st mounting unit 121 and the 2nd mounting unit 122 with which the same component mounting machine was equipped perform the component mounting operation | work of the substantially the same content. That is, the opposing first mounting unit 121 and second mounting unit 122 have substantially the same production time (unit production time) per substrate.

  For this reason, the first type of substrate that is loaded almost simultaneously into each of the first transport lane 111 and the second transport lane 112 is loaded into the opposing first mounting unit 121 and second mounting unit 122 almost simultaneously, and almost It is carried out at the same time. That is, the arrival timing of the board to each mounting unit is substantially synchronized or completely synchronized between the first transport lane 111 and the second transport lane 112.

  In the present embodiment, information indicating the number of component mounting boards to be produced in each of the first conveyance lane 111 and the second conveyance lane 112 is generated by the production quantity information generation device 200 for each type of board. The

  FIG. 3 is a block diagram illustrating a main functional configuration of the production number information generation device 200 according to the embodiment. In the present embodiment, the production number information generation device 200 is provided in the control device 105.

  The production number information generation device 200 includes a maximum setup time acquisition unit 201, a unit production time acquisition unit 202, a production number information generation unit 203, and an output unit 204.

  A basic processing flow of the production number information generation apparatus 200 including these components will be described with reference to FIGS. 4 and 5.

  FIG. 4 is a flowchart showing a basic processing flow of the production number information generation device 200 according to the embodiment.

  FIG. 5 is a diagram illustrating an example of information regarding the setup change of each component mounter 120 according to the embodiment.

  The maximum setup time acquisition unit 201 has a maximum setup time required for setup change required when the target board for component mounting is switched from the first board to the second board in each of the plurality of first mounting units 121. A first maximum time that is a setup time is acquired (S100). The first substrate and the second substrate are different types of substrates.

  The unit production time acquisition unit 202 is a first unit production time which is a time required for component mounting per one first board in the second mounting unit facing the first mounting unit 121 corresponding to the first maximum time. Is acquired (S110).

  For example, when the setup time corresponding to the type switching from the first board to the second board of each of the plurality of first mounting units 121 is the value shown in FIG. 5, the first mounting unit 121 of the component mounting machine [D] The setup time “180” is the maximum. Therefore, the maximum setup time acquisition unit 201 acquires “180” as the first maximum time.

  The unit production time acquisition unit 202 also has a unit production time of the second mounting unit 122 facing the first mounting unit 121 whose setup time is “180”, that is, the second mounting unit 122 of the component mounting machine [D]. “50” is acquired as the first unit production time.

  The production number information generation unit 203 generates production number information indicating a difference between the first production number and the second production number by using a value obtained by dividing the first maximum time by the first unit production time (S120). The first production number is the number of first substrates to be loaded into the first transfer lane 111, and the second production number is the number of first substrates to be loaded into the second transfer lane 112.

  In this example, the production number information generation unit 203 first obtains “3.6” from “180/50”. That is, this calculation result is obtained when the first mounting unit 121 of the component mounting machine [D] is performing the component changeover corresponding to the product type switching from the first board to the second board. The second mounting unit 122 in theory means that component mounting on 3.6 first boards is theoretically possible.

  In this case, in the present embodiment, in the component mounting machine [D], the number of the first boards on which the second mounting unit 122 should mount the components is determined by the number of the first boards on which the first mounting unit 121 should mount the components. Also increase 4 or more. Specifically, the second production number is increased by four or more than the first production number.

  Thus, the component mounting operation can be continued in the second mounting unit 122 facing the first mounting unit 121 in which the setup change is performed during the setup change period requiring the maximum time on the first transport lane 111 side. it can.

  Therefore, the production number information generation unit 203 determines, for example, “4” as the difference between the first production number and the second production number, and generates production number information indicating the difference.

  For example, the production number information generation unit 203 generates production number information indicating the numerical value “4” that is the difference.

  Alternatively, the production number information generation unit 203 determines the first production number and the second production number so that the difference between the first production number and the second production number is “4”, for example. Numerical values indicating the first production number and the second production number are generated as production number information. For example, when the total number of first substrates on which components are to be mounted is 200, “198” is determined as the first production number and “202” is determined as the second production number.

  The output unit 204 outputs the generated production number information (S130). For example, the output unit 204 outputs the production number information to the display device 106 connected to the control device 105. Thereby, the production number information is displayed on the display device 106.

  Various types of information processing by the production number information generation device 200 are realized by, for example, a CPU (Central Processing Unit) reading and executing a control program for each process.

  FIG. 6A is a diagram illustrating a display example of production number information in the embodiment, and FIG. 6B is a diagram illustrating another display example of production number information in the embodiment.

  As a result of the processing flow shown in FIG. 5, for example, as shown in FIG. 6A, information indicating that the second production number should be four more than the first production number is displayed on the display device 106. .

  In this case, for example, an operator who sees the information can put a substrate into each of the first transport lane 111 and the second transport lane 112 according to the information.

  For example, the operator sequentially inserts the first board into the first transport lane 111 and the second transport lane 112 one by one, and the remaining four (when the total number of first boards is an odd number of 5 or more) 5), the remaining number of first substrates can be loaded only into the second transport lane 112.

  In addition, as shown in FIG. 6B, when each production number is directly indicated by a numerical value, for example, an operator who has viewed the information puts 198 first substrates into the first transport lane 111, and 202 first substrates can be loaded into the second transfer lane 112.

  The same applies when the first substrate is loaded into each of the first transport lane 111 and the second transport lane 112 using a substrate loading device (for example, also called “loader”) that loads the substrate into the transport lane according to the setting. It is. For example, the operator may perform setting in accordance with the production number information displayed on the display device 106 in the substrate loading device.

  In this way, it is assumed that the first production number is 198 and the second production number is 202. In this case, the 198th first substrate in the first transport lane 111 is unloaded from the first mounting unit 121 of the component mounting machine [D], and almost simultaneously with this, the second mounting unit of the component mounting machine [D]. From 122, the 198th first substrate in the second transfer lane 112 is carried out.

  Thereafter, in the first mounting unit 121 of the component mounting machine [D], the setup change for mounting the component on the second board is started, while in the second mounting unit 122 of the component mounting machine [D], 199 is started. Component mounting on the first to 202nd first substrates is sequentially executed for each substrate.

  Here, the setup time in the first mounting unit 121 is 180 seconds, and the time required for the second mounting unit 122 to mount components on the four first boards is 200 seconds (50 seconds × 4). (See FIG. 5).

  Therefore, at least while the setup change of the first mounting unit 121 is being performed, the second installation unit 122 can be caused to perform component mounting on the first board, and the setup change is completed. After that, it is possible to change the setup of the second mounting unit 122 according to the type switching to the second board.

  Further, it is assumed that the maximum unit production time in the plurality of second mounting units 122 upstream of the second mounting unit 122 of the component mounting machine [D] is a value longer than 50 seconds, for example, 60 seconds. In this case, in the second mounting unit 122 of the component mounting machine [D], the carry-in interval of the first board becomes longer than 50 seconds.

  In addition, a device for temporarily storing the carried board is not connected to the downstream side of the second mounting unit 122 of the component mounting machine [D], and the maximum unit production in the plurality of downstream second mounting units 122 is performed. When the time is longer than 50 seconds, the unloadable interval of the first substrate is longer than 50 seconds.

  Accordingly, in any of the above cases, the time required for the second mounting unit 122 to mount the components on the four first substrates is longer than 200 seconds. However, there is no change in that the component mounting operation can be continued during the setup change of the first mounting unit 121 of the component mounting machine [D], and a decrease in production efficiency is suppressed.

  Thus, according to the production number information generation apparatus 200 of the present embodiment, production number information that can suppress a reduction in production efficiency due to setup change can be generated and output. Specifically, by using the production number information, the first mounting unit 121 is in the middle of executing the setup change requiring the maximum setup time on the first transport lane 111 side in the first mounting unit 121. Component mounting on the first board can be continued by the opposing second mounting unit 122.

  Here, since the first mounting unit 121 and the second mounting unit 122 that face each other perform component mounting work with substantially the same contents as described above, the setup time of the first mounting unit 121 and the second mounting unit There is a high probability that the setup time of the unit 122 is almost the same.

  That is, in the case of the above example, the second mounting unit 122 of the component mounting machine [D] is also considered to have a relatively long setup time.

  That is, by using the production number information generated by the production number information generation apparatus 200, in a group that requires a relatively long time for changeover among a plurality of groups composed of two opposing mounting units, 2 The timing of changing the setup of each of the two mounting units can be shifted.

  That is, by using the production number information of the present embodiment, among the plurality of sets, each mounting unit of the set that is considered to have the most influence on the production efficiency of the mounting line 110 from the viewpoint of the time required for the setup change. The timing of setup change can be shifted.

  Further, this deviation amount is also determined by using the other production possible number corresponding to one setup time, and therefore does not become unnecessarily large. As a result, for example, the occurrence of an inefficient state due to an increase in the time during which only one of the first transport lane 111 and the second transport lane 112 is operating is suppressed.

  In the production number information generation device 200 of the present embodiment, the maximum setup time acquisition unit 201 acquires the setup times of each of the plurality of first mounting units 121, but this acquisition method is not limited to a specific method. It is not limited.

  For example, the maximum setup time acquisition unit 201 may acquire the setup time from each of the plurality of first mounting units 121 via a communication network. Further, the maximum setup time acquisition unit 201 may acquire these setup times from an external database, for example.

  Further, the maximum setup time acquisition unit 201 may calculate these setup times, for example.

  FIG. 7 is a diagram illustrating a data configuration example of the setup information 230 in the embodiment, and FIG. 8 is a diagram illustrating a data configuration example of the setup time database 235 in the embodiment.

  The maximum setup time acquisition unit 201 acquires, for example, setup information 230 indicating the content of setup change when switching the product type from the first board to the second board of the first mounting unit 121 from the component mounting machine [D].

  Furthermore, the maximum setup time acquisition unit 201 refers to a setup time database 235 that stores individual times that are required times for a plurality of work contents. Note that the setup time database 235 is stored in a device such as the control device 105 that is communicably connected to the maximum setup time acquisition unit 201.

  From the setup information 230 and the setup time database 235, the maximum setup time acquisition unit 201 calculates the setup time when switching the product type from the first mounting unit 121 of the component mounter [D] and the first board to the second board. To do.

  In the case of the example shown in FIGS. 7 and 8, the work contents shown in the setup information 230 are “part cassette replacement: 5” and “nozzle replacement: 3”, and the individual time for parts cassette replacement is 30. Therefore, the setup time is calculated as 180 seconds from (5 × 30) + (3 × 10).

  The maximum setup time acquisition unit 201 can calculate the setup time for the other mounting units from the setup information 230 corresponding to the other mounting units and the setup time database 235 as well.

  Further, the method by which the unit production time acquisition unit 202 acquires the unit production time is not limited to a specific method. The unit production time acquisition unit 202 may acquire the unit production time from each of the plurality of second mounting units 122 via a communication network, for example. Further, the unit production time acquisition unit 202 may acquire these unit production times from an external database, for example.

  Further, the production number information may be output to the substrate loading device instead of or in addition to being displayed on the display device 106. That is, by inputting the production number information to the substrate loading apparatus, the substrate loading apparatus may be operated according to the production number information.

  FIG. 9 is a diagram showing an outline when a substrate loading apparatus is installed on the mounting line 110 in the embodiment.

  In FIG. 9, the board loading device 300 is installed upstream of the plurality of component mounting machines 120 in the mounting line 110. For example, when the difference “4” between the first production number and the second production number is given as the production number information, the substrate loading apparatus 300 uses the total number of the first substrates and “4” to obtain the first production number information. The production number and the second production number are calculated. The substrate loading apparatus 300 further loads the first substrate one by one sequentially into each of the first transport lane 111 and the second transport lane 112 according to the calculation result.

  Further, the substrate loading apparatus 300, for example, sequentially inserts the first substrate into each of the first transport lane 111 and the second transport lane 112, and the remaining four (the total number of first substrates is 5 or more). The remaining number of the first substrates may be put into only the second transport lane 112 when the number of the first substrates reaches 5).

  Thus, by making the mounting line 110 use the production number information without using an operator, for example, the production efficiency of the mounting line 110 can be improved.

  The production number information generation method and production number information generation apparatus according to the present invention have been described above based on the embodiments. However, the present invention is not limited to the above embodiment. Unless it deviates from the meaning of this invention, the form which carried out the various deformation | transformation which those skilled in the art thinks to the said embodiment, or the form constructed | assembled combining the several component demonstrated above is also in the scope of the present invention. included.

  For example, in the present embodiment, the production number information is generated using the maximum setup time on the first transport lane 111 side. However, the production number information may be generated using the maximum setup time on the second transport lane 112 side. In other words, if the number of pieces of production information is generated using the maximum setup time on either one of the two transport lanes and the unit production time of the mounting unit facing the mounting unit that requires the maximum setup time, Good.

  Further, in the present embodiment, the flow of processing for generating production number information for product type switching from the first substrate to the second substrate has been mainly described.

  However, the production number information generation apparatus 200 can also generate production number information for product type switching from the second substrate to the third substrate, which is the third type of substrate.

  Specifically, the maximum setup time acquisition unit 201 is a second maximum time that is the maximum setup time among the setup times when switching the product type from the second board to the third board of the plurality of first mounting units. To get.

  The unit production time acquisition unit 202 is a second unit production time, which is a time required for component mounting per second board in the second mounting unit 122 facing the first mounting unit 121 corresponding to the second maximum time. To get.

  The production number information generation unit 203 uses the difference between the previously determined first production number and the second production number, and a value obtained by dividing the second maximum time by the second unit production time. Production number information indicating a difference between the number of the second substrates to be loaded into the lane and the number of the second substrates to be loaded into the second transfer lane is generated. The output unit 204 outputs the generated production number information.

  As described above, the production number information generation unit 203 determines the first production number and the second production number that are determined in advance when allocating the second substrate to the first conveyance lane 111 and the second conveyance lane 112. And the difference can be taken into account.

  For example, the difference between the first production number and the second production number is “4” as described above, and the value P obtained by dividing the second maximum time by the second unit production time is 6 <P ≦ 7. Assuming that

  In this case, at the stage where the board to be mounted is the first board, there are already four differences in the board distribution of the first transport lane 111 and the second transport lane 112. Therefore, for example, the production number information generation unit 203 sets “3” as the difference between the number of the second substrate to be put into the first transport lane and the number of the second substrate to be put into the second transport lane. The production number information indicating is generated.

  As described above, the production number information generation unit 203 faces the first mounting unit at the timing of the changeover of the first mounting unit that requires the maximum setup time for the product type switching from the second board to the third board. The production number information for shifting the setup change timing of the second mounting unit by an appropriate amount can be generated.

  Further, in the present embodiment, the mounting line 110 is formed by connecting a plurality of component mounting machines 120 including a pair of mounting units arranged to face each other.

  However, a set of mounting units constituting a part of the mounting line 110 may not constitute one component mounter.

  FIG. 10 is a schematic diagram showing another configuration example of the production system 100 according to the embodiment of the present invention.

  The production system 100 shown in FIG. 10 includes a mounting line 510, and the mounting line 510 includes a plurality of sets of first mounting units 521 and second mounting units 522 arranged to face each other.

  Moreover, the 1st conveyance lane 511 and the 2nd conveyance lane 512 are formed by connecting the conveying apparatus which these mounting units have.

  The mounting line 510 is connected to the control device 105 via a communication network, and the production number information generation device 200 included in the control device 105 generates production number information about the mounting line 510, for example, the display device 106. Output to.

  Here, when the group of the first mounting unit 521 and the second mounting unit 522 arranged to face each other on the mounting line 510 is named [A] group to [F] group from the right, [A] group to [[ Each of the F] sets corresponds to the component mounter [A] to the component mounter [F] in the embodiment.

  That is, as shown in FIG. 10, even if two mounting units arranged opposite to each other are physically separated, if the two units operate so as to synchronize with each other, By using the production number information generated by the information generation device 200, a decrease in production efficiency due to setup change is suppressed.

  Further, in the mounting line 510, by providing a passage so as to penetrate between two opposing mounting units in each group, the operator can sequentially and efficiently perform the setup change of each of the two mounting units in each group. The effect is demonstrated.

  When the two mounting units are arranged to face each other, it is not necessary to arrange the two mounting units in parallel in the direction (Y-axis direction) orthogonal to the substrate transport direction as shown in FIGS. That is, it is only necessary to arrange two mounting units in each group so that two transport lanes are formed when a plurality of sets of two mounting units are connected. Thereby, “a set of mounting units arranged to face each other” is realized.

  INDUSTRIAL APPLICABILITY The present invention is useful as a production number information generation method, a production number information generation apparatus, and the like for suppressing a decrease in production efficiency due to setup change in a mounting line having two conveyance lanes.
