2. Description of the Related Art Conventionally, a component mounting machine is known in which components are sequentially picked up by a nozzle from a plurality of feeders arranged in a slot of a feeder set base and mounted on a substrate. As such a component mounting machine, there is known a device that proposes a method of arranging feeders arranged on a feeder set base so that the moving time or moving distance of a component picking head holding a nozzle is optimized (for example, Patent Document 1). .

JP 2013-51240 A

However, when a predetermined number of parts mounting boards of the same type are manufactured, a feeder that supplies a large number of parts to be mounted on one board may have to be replaced several times along the way. In that case, workability at the time of exchanging feeders varies greatly depending on how the feeders are arranged. There is no known method for arranging feeders considering such workability.

The present invention has been made to solve such a problem, and in order to manufacture a predetermined number of component mounting boards of the same type, the feeders are arranged in consideration of workability when the feeders are arranged on the feeder set base. The main purpose is to provide indicators of

The mounting management apparatus of the present invention
A mounting management device that manages a component mounting machine that sequentially collects components from a plurality of feeders arranged on a feeder set stand and mounts them on a board,
Storage means for storing factors necessary for calculating an individual placement time index taking into account workability when placing the feeder on the feeder set base;
In manufacturing a predetermined number of component mounting boards of the same type, the individual placement time index of each of the plurality of feeders is calculated using the factor, and based on the calculated individual placement time index of all the feeders Calculating means for calculating all feeder arrangement time indexes required to manufacture the predetermined number of the component mounting boards;
It is equipped with.

In this mounting management apparatus, when a predetermined number of component mounting boards of the same type are manufactured, first, an individual placement time index is added for each of the plurality of feeders, taking into account workability when placing the feeders on the feeder set base. Then, based on the calculated individual placement time indexes of all feeders, all feeder placement time indexes required for such production are calculated. The individual arrangement time index is an index that takes into account workability when the feeder is arranged on the feeder set base. Such workability varies depending on how the feeders are arranged. For this reason, the individual arrangement time index also changes depending on how the feeders are arranged. The all feeder arrangement time index is an index of time required to manufacture a predetermined number of component mounting boards of the same type, and is calculated based on the individual arrangement time index of all feeders. Therefore, the total feeder arrangement time index also changes depending on how the feeders are arranged. Therefore, when producing a predetermined number of component mounting boards of the same type, all feeder arrangement time indicators can be used as indicators for arranging feeders in consideration of workability when the feeders are arranged on the feeder set base.

In the mounting management apparatus of the present invention, the factors may include environmental factors related to the arrangement environment on the left and right sides of each feeder. Environmental factors are factors that vary depending on how the feeders are arranged. For this reason, it is preferable to calculate the individual placement time index, and thus the total feeder placement time index, using environmental factors.

Here, the environmental factor may include at least one of a first sub-factor related to the arrangement work space on the left and right sides of each feeder and a second sub-factor related to the adjacent feeder. Since the first and second sub-factors are greatly influenced by how the feeders are arranged, it is preferable to include them as environmental factors.

At this time, the first sub-factor is determined so that a value closer to the feeder among slots on the left and right sides of the feeder is larger, and the second sub-factor is arranged so that two feeders are adjacent to each other. In this case, the smaller the gap between the two feeders, the larger the value may be set. By doing so, the values of the first and second sub-factors increase as the influence of the arrangement operation is increased, and as a result, the value of the total feeder arrangement time index also increases.

In the mounting management apparatus of the present invention, the factor includes, in addition to the environmental factor, a single placement factor related to a standard single placement time when each feeder is placed on the feeder set stand alone, and the component An arrangement frequency factor related to the arrangement frequency of each feeder required to manufacture the predetermined number of mounting substrates may be included. In this way, the individual placement time index can be regarded as the work time required to place one feeder when a predetermined number of the same type of component mounting boards are manufactured.

In the mounting management apparatus of the present invention, the calculation means uses the total of the individual arrangement time indexes of the plurality of feeders as the total feeder arrangement time index for each of a plurality of ways of arranging the feeders, and calculates the total feeder arrangement The arrangement of the feeders may be determined so that the time index is minimized. In this way, it is possible to propose a method for arranging the feeders so that the entire feeder arrangement time is as short as possible.

In the mounting management apparatus of the present invention, the calculation means calculates the total of the individual arrangement time indexes of the plurality of feeders as the total feeder arrangement time index for each of a plurality of ways of arranging the feeders, and the component mounter Calculates the time required to produce one component mounting board as a board production time index, and arranges the feeders so that the total of the calculated feeder placement time index and the board production time index is minimized. You may decide. In this way, it is possible to propose a feeder arrangement method in which the total of the total feeder arrangement time and the substrate production time is as short as possible.

In the present embodiment, the left-right direction (X-axis), the front-rear direction (Y-axis), and the up-down direction (Z-axis) are as shown in FIGS.

As shown in FIG. 1, the component mounting system 1 includes a plurality of component mounters 10 that form a mounting line, and a mounting management device 80 that manages the production of a board. In the component mounting system 1, each component mounter 10 mounts components on the substrate 12 carried in from the upstream side, and the substrate 12 after component mounting is unloaded.

As shown in FIG. 2, the component mounter 10 includes a board transfer device 18, a head unit 34, a parts camera 39, a feeder 40, a feeder set base 60, and a mounting controller 70.

The substrate transport device 18 is provided with

support plates

20 and 20 provided at intervals in the front and rear direction of FIG. 2 and extending in the left-right direction, and

conveyor belts

22 and 22 provided on the mutually opposing surfaces of the support plates 20 and 20 (FIG. 1 shows only one of them). The

conveyor belts

22 and 22 are stretched over the drive wheels and the driven wheels provided on the left and right sides of the

support plates

20 and 20 so as to be endless. The substrate 12 is carried on the upper surfaces of the pair of

conveyor belts

22 and 22 and is conveyed from left to right. The substrate 12 is supported by a large number of support pins 23 erected on the back side.

The head unit 34 is detachably attached to the front surface of the X-axis slider 26. The head unit 34 has a handle 35 on the front surface to be gripped by an operator during replacement work. The X-axis slider 26 is slidably attached to a pair of upper and

lower guide rails

28, 28 provided in front of the Y-axis slider 30 and extending in the left-right direction. The Y-axis slider 30 is slidably attached to a pair of left and right guide rails 32, 32 extending in the front-rear direction. The head unit 34 moves in the left-right direction as the X-axis slider 26 moves in the left-right direction, and moves in the front-rear direction as the Y-axis slider 30 moves in the front-rear direction. Each

slider

26, 30 is driven by a drive motor (not shown). The head unit 34 has a rotary head 36 having a plurality of suction nozzles 38. The suction nozzle 38 uses pressure to suck a component at the tip of the nozzle or release a component sucked at the tip of the nozzle. The height of the suction nozzle 38 can be adjusted by a Z-axis motor (not shown) mounted on the head unit 34. Such a suction nozzle 38 is appropriately replaced in accordance with the type and size of the component.

The parts camera 39 is installed between the feeder set base 60 and the substrate transfer device 18 so that the imaging direction is upward at the approximate center of the length in the left-right direction. The parts camera 39 images the parts sucked by the suction nozzle 38 passing above, and outputs an image obtained by the imaging to the mounting controller 70.

The feeder 40 rotatably holds a reel 42 around which a tape 44 is wound, as shown in FIG. A plurality of recesses 46 are formed in the tape 44 so as to be arranged along the longitudinal direction of the tape 44. Each recess 46 accommodates a part P. These parts P are protected by a film 48 that covers the surface of the tape 44. The feeder 40 has a component suction position. The component suction position is a position determined by design in which the suction nozzle 38 sucks the component P. Each time the tape 44 is fed backward by a predetermined amount by the feeder 40, the parts P accommodated in the tape 44 are sequentially arranged at the parts suction position. The part P that has reached the part suction position is in a state where the film 48 is peeled off, and is sucked by the suction nozzle 38. The width of the tape 44 increases as the size of the component P increases, the width of the reel 42 increases as the width of the tape 44 increases, and the width of the feeder 40 increases as the width of the reel 42 increases. Therefore, there are feeders having various widths depending on the size of the part P.

The feeder set base 60 has a plurality of slots 62 on its upper surface as shown in FIG. The slots 62 are grooves extending along the Y axis, and a plurality of slots 62 are provided in a row on the upper surface of the feeder set base 60 along the X axis. A rail (not shown) provided on the lower surface of the feeder 40 is inserted into the slot 62. The feeder set base 60 has a standing wall at the rear end. The standing wall is provided with a connector 65 at a position corresponding to each slot 62, and positioning holes 66 and 67 are provided above and below each connector 65. When the feeder 40 is inserted into the slot 62, two positioning pins and connectors (not shown) provided on the rear end surface of the feeder 40 are connected to the positioning holes 66 and 67 of the feeder set base 60 and the connector 75, respectively. The feeder 40 occupies only one slot 62 when it is narrow, but occupies a plurality of slots 62 when it is wide.

As shown in FIG. 2, the mounting controller 70 is configured as a microprocessor centered on a CPU, and includes a ROM that stores processing programs, an HDD that stores various data, a RAM that is used as a work area, and the like. These are electrically connected via a bus (not shown). The mounting controller 70 is connected to a feeder controller (not shown) of the feeder 40 and a mounting management device 80 so as to be capable of bidirectional communication. Further, the mounting controller 70 is connected so as to be able to output control signals to the substrate transport device 18, the X-axis slider 26, the Y-axis slider 30, the Z-axis motor, etc. Has been. For example, the mounting controller 70 picks up the component P from the component supply tape sent to the component supply position by each feeder 40 by the suction nozzle 38 on the basis of the production program received from the mounting management device 80 and performs predetermined processing on the substrate 12. The substrate transport device 18, the X-axis slider 26, the Y-axis slider 30, the Z-axis motor, and the like are controlled so as to be sequentially mounted at the positions. Further, the mounting controller 70 determines whether or not a component is attracted to the suction nozzle 38 based on an image captured by the parts camera 39, and determines the shape, size, suction position, and the like of the component.

As shown in FIG. 1, the mounting management apparatus 80 is a microprocessor centered on a CPU 81, and includes a ROM 82 that stores a processing program, an HDD 83 that stores a board production program, and a RAM 84 that is used as a work area. . These are electrically connected via a bus (not shown). An input signal is input to the mounting management device 80 from an input device 85 such as a mouse or a keyboard, and an image signal to the display 86 is output from the mounting management device 80.

Next, a mounting optimization processing routine executed by the mounting management device 80 of the component mounting system 1 configured as described above will be described. FIG. 5 is a flowchart of a mounting optimization processing routine. Here, a case where a predetermined number of component mounting boards of the same type are manufactured will be described as an example.

When this mounting optimization processing routine is started, the CPU 81 of the mounting management device 80 reads the current production program data from the HDD 83 (step S100). The production program is a program related to a plan that determines what parts are to be mounted on a board and how many boards on which such parts are mounted. Such a production program is stored in the HDD 83 of the mounting management apparatus 80 when the operator operates the input device 85. The production program data includes production date and time, the number of substrates to be manufactured, component information about components to be mounted on the substrate, head information about the head to be used, nozzle information about the suction nozzle mounted on the head, and the like.

Next, the CPU 81 of the mounting management device 80 sets a mounting sequence (step S200). Specifically, the CPU 81 sets a mounting sequence by designating a component type, a mounting position (X coordinate, Y coordinate) and a type of suction nozzle to be used (used nozzle type) in the mounting order. The used nozzle type is set to a suction nozzle having a large nozzle diameter from among the types of suction nozzles that can suck parts and do not interfere with adjacent mounted parts.

Next, the CPU 81 of the mounting management device 80 distributes the mounting sequence to each component mounting machine 10 (step S300). Specifically, the CPU 81 distributes so that the number of mounting sequences distributed to each component mounter 10 is equal or as even as possible. In each mounting sequence, which feeder component is to be mounted is determined. Therefore, how many feeders 40 are mounted on each component mounter 10 is determined by the distribution of the mounting sequence.

Next, the CPU 81 of the mounting management device 80 calculates the mounting order of components for each component mounting machine 10 (step S400). At this time, the CPU 81 calculates the mounting order so that, for example, when the components are mounted on the substrate, the mounting of the components is not hindered by the previously mounted components.

Next, the CPU 81 of the mounting management apparatus 80 executes a feeder arrangement determining routine for determining the arrangement of the feeders 40 for each component mounting machine 10 (step S500). Taking one component mounter 10 as an example, based on the mounting sequence allocated to the component mounter 10, a plurality of feeder arrangement methods are created, and the optimum feeder arrangement method is selected from among them. Is determined as a method of arranging the feeders of the component mounter 10. Details of this routine will be described later. Thereby, in each component mounting machine 10, how to arrange the feeders 40 is determined. Thereafter, the CPU 81 stores the production program including the arrangement method in the HDD 83 (step S600), and ends this routine.

Here, the feeder arrangement method determination routine (step S500) will be described with reference to the flowchart of FIG. Here, for convenience, a routine for setting the mounting position of the feeder 40 allocated to one component mounting machine 10 will be described. In practice, this routine is performed for all the component mounting machines 10 constituting the component mounting system 1. Execute.

Before this routine is executed, the HDD 83 stores factors necessary for calculating an individual placement time index that takes into account workability when placing the feeder 40 on the feeder set base 60. As shown in FIG. 7, these factors include a single arrangement factor and an arrangement frequency factor in addition to environmental factors.

The environmental factor is a factor related to the arrangement environment on the left and right sides of each feeder 40. In this embodiment, the environmental factor is related to the first sub-factor related to the arrangement work space on the left and right sides of each feeder and the adjacent feeder. Sub-factors.

An example of the numerical value S representing the first subfactor is shown in FIG. In FIG. 8, it is assumed that the feeder 40 includes three types of a feeder A having a narrow width, a feeder B having a medium width, and a feeder C having a wide width. For each of the feeders A, B, and C, a numerical value S representing the first subfactor is set. In the following description, numerical values S _Lm and S _Rm are used. Of the subscripts Lm and Rm after S, L is the slot 62 on the left side of the feeder to be placed (placement target feeder). R means that it is the slot 62 on the right side of the placement target feeder, and m means that it is the m th slot 62 from the slot 62 into which the placement target feeder is inserted.

The feeder A has a width that occupies one slot 62. In the first slot 62 on the left side of the feeder A, a value 1 is set as a numerical value S _L1 . In the first slot 62 on the right side of the feeder A, a value 1 is set as a numerical value S _R1 . The feeder B has a width that occupies the three slots 62. In the first slot 62 on the left side of the feeder B, a value 3 is set as the numerical value S _L1 , and in the second slot 62, a value 1 is set as the numerical value S _L2 . Further, a value 3 is set as a numerical value S _{R1 in} the first slot 62 on the right side of the feeder B, and a value 1 is set as a numerical value S _{R2 in the} second slot 62. The feeder C has a width that occupies the five slots 62. In the first slot 62 on the left side of the feeder C, a value 5 is set as a numerical value S _L1 , a value 3 is set as a numerical value S _{L2 in the} second slot 62, and a numerical value S is set in the third slot 62. _The value 1 is set as _L3 . The first slot 62 on the right side of the feeder C is set to a value 5 as a numerical value S _R1 , the second slot 62 is set to a value 3 as a numerical value S _R2 , and the third slot 62 is a numerical value. The value 1 is set as S _R3 .

Thus, the numerical value S representing the first sub-factor has an effect on workability when inserting the feeder into the slot 62 in the slots 62 closer to the feeder among the left and right sides of the slot 62 into which the placement target feeder is inserted. Since the value is large, the value is set to be large. In addition, since the work load increases as the width of the placement target feeder increases, the value is determined to increase.

An example of the numerical value K representing the second subfactor is shown in Table 1. In Table 1, a numerical value K is set according to the relationship between the placement target feeder and the surrounding feeders. The width of each feeder is not necessarily made an integral multiple of the slot width. The width of the feeder depends on the width of the target tape. For this reason, when each feeder occupies the slot 62, there are a feeder that occupies the entire slot width and a feeder that occupies a gap left and right. As a result, when the feeders are arranged adjacent to each other, there are cases where the two feeders are in contact with each other without a gap, and there are cases where a little gap is left. In the case of a combination that touches without a gap, it is difficult to perform the arrangement work. On the other hand, the larger the gap, the easier the work. Therefore, in Table 1, the values are set so as to increase as the gap between the two feeders becomes smaller when they are arranged adjacent to each other. For example, when the feeder to be arranged is the feeder A, the numerical value K is set to a small value of 1.0 even if the surrounding feeder is any of the feeders A, B, and C. This is because the feeder A occupies the slot 62 with a large gap between the left and right, so that when the feeder A is inserted into the slot 62, a sufficient gap is formed between the feeder A and any feeder. For this reason, workability when the feeder A is arranged does not deteriorate so much. When the placement target feeders are feeders B and C, the width occupied with respect to the slot width is relatively large, and a gap is hardly generated. For this reason, the numerical value K is set to be a large value. Thus, the numerical value K representing the second sub-factor is determined such that the value increases as the gap between the two feeders becomes smaller when the two feeders are arranged adjacent to each other.

Next, a single arrangement factor will be described. The single placement factor is a factor related to a standard single placement time when each feeder is placed on the feeder set base 60 alone. Let this single arrangement factor be t.
An example of the relationship between the feeder and the single placement factor is shown in Table 2. As shown in Table 2, since the work load when inserting the feeder into the slot 62 increases as the width of the placement target feeder increases, the single placement factor t is set to increase. Here, the standard single unit arrangement time of the feeder A is defined as a value 1, and the ratio of the standard single unit arrangement time of the feeders B and C to the value is expressed as a numerical value t.

Next, the placement frequency factor will be described. The arrangement frequency factor is a factor related to the arrangement frequency of each feeder required to manufacture a predetermined number of component mounting boards. This arrangement frequency factor is N. Table 3 shows an example of the relationship between the feeder and the arrangement frequency factor. Regarding the number of feeders arranged, the more the number of components supplied by the feeder is mounted per board, the greater the number of feeder replacements. In Table 3, feeders A-1, A-2, and A-3 (using the same feeder A but different parts to be supplied) are set to 5 times, feeder B is set to 3 times, and feeder C is set to 1 time. Has been. Since the number of times of feeder replacement is greatly related to the work time when the feeder is inserted into the slot, the number of feeder replacement itself is used as the arrangement number factor N here. Note that the number of replacements is also counted as one when the feeder is first set on the feeder set base 60.

When starting the feeder arrangement method determination routine, the CPU 81 first creates a plurality of feeder arrangement methods based on the mounting sequence allocated to the component mounter 10 (step S510). Specifically, the CPU 81 selects necessary feeders according to the mounting sequence allocated to the component mounter 10, and creates a plurality of ways of arranging these feeders using concepts such as permutations and combinations. Here, for the sake of convenience, the description will be made assuming that the two arrangements shown in FIG. 9 and the arrangement shown in FIG. 10 are created. 9 and 10, it is assumed that the feeder set base 60 is provided with a total of 23 slots 62 from No. 1 to No. 23. FIG. 9 is an example of an arrangement in which feeders are packed and arranged so that there is no empty slot between the feeders. FIG. 10 is an example of an arrangement in which feeders are arranged so that empty slots are formed around feeders B and C. It is an example.

Next, the CPU 81 calculates the total of the individual arrangement time index T _{k as} the total feeder arrangement time index T _SUM for each of the plurality of ways of arranging the feeders (step S520). Specifically, for each arrangement, the individual placement time index T _k of each of the plurality of feeders is set to the first and second sub-factors S and K constituting the environmental factor, the single placement factor t, the placement frequency factor N, And the total ΣT _k is calculated as the total feeder arrangement time index T _SUM . An example of an arithmetic expression for the individual arrangement time index T _k is shown in the following expression (1). Further, C _k in the equation (1) is calculated by the following equation (2). 9 and 10 show the values of the individual placement time indexes T ₁ to T ₅ of each feeder and the values of all the feeder placement time indexes T _{SUM in} the respective arrangement methods.

T _k = (t _k + C _k ) * N _k (1)
T _k : Individual placement time index T of the kth feeder from the left among the feeders set on the feeder set stand
t _k : single placement factor t of the k th feeder
N _k : arrangement factor N of the kth feeder
C _k : correction term C of the k th feeder
k: an integer greater than or equal to 1

C _k = (S _L1k * K _L1k + S _L2k * K _L2k + ...) + (S _R1k * K _R1k + S _R2k * K _R2k + ...) (2)
S _Lmk : Numerical value S assigned to the mth slot from the left of the kth feeder
K _Lmk : Numerical value K assigned by the relationship between the kth feeder and the feeder that occupies the mth slot from the left of the feeder
S _Rmk : Numerical value S assigned to the mth slot from the right of the kth feeder
K _Rmk : Numerical value K assigned by the relationship between the kth feeder and the feeder occupying the mth slot from the right of the feeder
m: an integer greater than or equal to 1

Next, the CPU 81 determines the feeder arrangement that minimizes the calculated total feeder arrangement time index T _SUM as the recommended feeder arrangement this time (step S530), and displays it on the display 86 (step S540). This routine ends. In this example, since the value of the total feeder arrangement time index T _SUM is smaller in FIG. 9 than in FIG. 10, the CPU 81 determines the arrangement in FIG. 86.

By the way, the individual arrangement time index T _k is an index considering workability when the feeder 40 is arranged on the feeder set base 60. Such workability varies depending on how the feeders 40 are arranged (for example, whether or not the feeders 40 are arranged next to each other, and what kind of feeders 40 are arranged). For this reason, the individual arrangement time index T _k also changes depending on how the feeders 40 are arranged. All feeders arranged time index T _SUM is the same type of component mounting substrate is indicative of time required for a predetermined number of production, in which is calculated as the sum of the individual arrangement time index T _k of all feeders 40. Therefore, the total feeder arrangement time index _TSUM also changes depending on how the feeders 40 are arranged.

Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The HDD 83 of this embodiment corresponds to the storage unit of the present invention, and the CPU 81 corresponds to the calculation unit.

According to the mounting management device 80 of the present embodiment described above, when a predetermined number of component mounting boards of the same type are manufactured, all feeder placement time indices _TSUM are used, and work when placing the feeder 40 on the feeder set base 60 is performed. This can be used as an index for arranging the feeders 40 in consideration of the characteristics.

The environmental factors (first and second sub-factors) are factors that change depending on how the feeders are arranged. Since the individual placement time index T _{k and} thus the total feeder placement time index T _SUM are calculated using this environmental factor, an appropriate index can be obtained.

Further, the first subfactor is determined such that the slot closer to the feeder out of the left and right side slots of the feeder has a larger value, and the second subfactor is determined when the two feeders are arranged adjacent to each other. The value is determined to be larger as the feeder gap is smaller. For this reason, the value of each sub-factor increases as the influence of the arrangement work is increased, and as a result, the value of the total feeder arrangement time index T _SUM also increases.

And also, in addition to the environmental factors, since the computed indicators T _k individual arrangement time using the arrangement number factors as simplex arrangement factor, individual arrangement time indicator T _k, when a predetermined number of manufacturing the same type of component mounting board It can be regarded as the work time required to arrange one feeder.

Furthermore, it is possible to display on the display 86 how to arrange the feeders so that the total feeder arrangement time is as short as possible, and to propose to the operator.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

In the above-described embodiment, the recommended feeder arrangement is determined such that the total feeder arrangement time index T _SUM is obtained for each of a plurality of feeder arrangement methods and is minimized, but is determined by other methods. May be. For example, the time component mounting apparatus 10 is required to produce a single component mounting board is calculated as the substrate production time index T _pro, total minimum the total feeder arranged time index T _SUM and board production time index T _pro The recommended feeder arrangement may be determined so that The suction nozzle 38 picks up the component P supplied by the feeder 40, sucks the component P, moves to a predetermined position of the substrate 12 through the position above the parts camera 39, and releases the component P there. A series of operations are repeated for all the parts to be mounted on the substrate 12. In the mounting sequence, a component type, a mounting position (X coordinate, Y coordinate) and a type of suction nozzle to be used (used nozzle type) are specified in the mounting order. Therefore, if the arrangement of the feeders 40 is determined, the time required for the component mounter 10 to produce one component mounting board, that is, the board production time index T _pro can be calculated by simulation. In this way, it is possible to propose a feeder arrangement method in which the total of the total feeder arrangement time and the substrate production time is as short as possible. If an attempt is made to shorten the total feeder arrangement time, the board production time may become longer. Conversely, if an attempt is made to shorten the board production time, the entire feeder arrangement time may become longer. For this reason, it is considered that selection of feeders that minimizes the sum of the two is the best choice.

Instead of the total feeder arrangement time index T _SUM of the above-described embodiment, the total of correction terms C _k related to environmental factors, that is, ΣC _k may be used as the total feeder arrangement time index. This correction term C _k varies depending on the arrangement environment on both the left and right sides of the feeder, that is, how the feeders are arranged, as shown in the above equation (2). On the other hand, the single arrangement factor t _k and the arrangement frequency factor K _k do not change depending on how the feeders are arranged. Therefore, ΣC _k can be used as an index for arranging the feeders 40 in consideration of workability when the feeders 40 are arranged on the feeder set base 60.

In the above-described embodiment, the environmental factor has been described as including both the first subfactor and the second subfactor, but either one may be included. Or you may make it include the subfactor related to an environment different from the 1st and 2nd subfactor.

In the above-described embodiment, T _SUM is obtained from the above equation (1), but is not limited to the above equation (1), and any other equation including three factors t _k , C _k , and N _k may be used. The following formula may also be used.

In the above-described embodiment, C _k is obtained from the above equation (2), but is not limited to the above equation (2), and is a numerical value S representing the first subfactor and a numerical value representing the second subfactor. Other formulas may be used as long as they include K. For example, C _k may be obtained by the above formula (2 ′).
C _k = ((S _L1k + K _L1k ) + (S _L2k + K _L2k ) + ...) + ((S _R1k + K _R1k ) + (S _R2k * K _R2k ) + ...) (2 ')

It goes without saying that the numerical values representing the factors shown in the above-described embodiments are merely examples, and other numerical values may be adopted.
