Description

  The present invention relates to a support apparatus, and more particularly, to a support apparatus that supports preparation for replacement work between a storage section in use and a preliminary storage section in a mounting apparatus that collects components and mounts them on a substrate.

  Conventionally, a mounting apparatus for mounting an electronic component on a substrate is known. As such a mounting apparatus, an apparatus including a component supply unit, a component transfer unit, and a preliminary storage unit is known. The component supply unit includes a plurality of feeders that accommodate and supply different types of components. The component transfer unit collects components supplied by each feeder of the component supply unit and mounts them on the substrate. The spare storage unit stores a spare feeder that accommodates parts of the same type as the feeder being used in the parts supply unit. A plurality of such mounting devices are arranged in the production line. The board is transported from the upstream to the downstream of the production line by the conveyor to each mounting apparatus, and various components are mounted on each mounting apparatus. In the mounting apparatus, when a feeder in use becomes out of parts, a spare feeder is adopted as the feeder in use. Then, the spare feeder disappears, and a new spare feeder is supplied. Patent Document 1 discloses an apparatus for determining an operator who performs such replenishment work. Further, Patent Document 2 discloses a component management computer that manages the component expiration time.

  By the way, a considerable number of feeders are in use on the production line. Further, the time required for the feeder in use to run out of parts varies depending on the number of parts held on the tape, the number of parts mounted on one board, and the like. For this reason, the timing at which a feeder in use is out of components varies depending on each feeder, but in some cases, many feeders may be out of components at the same time. If a large number of feeders run out of parts at once, the burden on the operator in charge of replacement work becomes too great, which may cause a situation where the production line must be stopped.

  The present invention has been made in order to solve such a problem, and has as its main object to level the replacement work between the spare storage unit storing the parts and the storage unit in use regardless of the timing.

The support device of the present invention
Mounting device including a component supply unit including a plurality of storage units that store and supply different types of components, and a mounting processing unit that collects components from the storage units of the component supply unit and mounts them on a substrate A spare storage unit that stores the same type of component as the storage unit in use in the component supply unit, and a support device that assists in preparation for replacement work with the storage unit in use,
Using the total number of parts included in the specific storage unit and a predetermined change value different from the other storage units, the predetermined used part number and / or the predetermined remaining part number of the specific storage unit are replaced A setting means for setting the number of parts;
Output means for outputting replacement information related to the set replacement time part number;
It is equipped with.

  In this support device, it is necessary to replace at least one of the number of used parts and the number of remaining parts of the specific storage unit by using the total number of parts included in the specific storage unit and a predetermined change value different from the other storage units. Set to the number of parts, and output replacement information related to the set number of parts for replacement. Thereafter, using this output exchange information, the operator is notified of the replacement time of the storage unit. As described above, since the number of parts for replacement with the spare storage unit is different in each storage unit, the replacement time of the spare storage unit to be replaced in a certain work period is different from that of the other standby storage unit. It becomes difficult to overlap with the replacement time. Therefore, it is possible to level the replacement work between the spare storage unit storing the parts and the storage unit in use regardless of the time. Here, examples of the “predetermined change value” include a coefficient (for example, less than 1) that is multiplied by the total number of parts, an addition / subtraction number that is added to or subtracted from the total number of parts, and the like. Further, the “replacement information” may include the number of replacement time parts, and in addition to or instead of this, information that can be used to derive the number of replacement time parts, for example, a change value is included. It may be a thing.

  In the support apparatus according to the present invention, the setting unit may set the change values of the specific storage unit and the other storage units to different values using a random variable. In this way, the replacement work can be leveled relatively easily by using random variables.

  In the support device of the present invention, the setting means sets the used parts number in the range of 80% or less of the total number of parts in the housing part as the replacement time part number, or the total parts in the housing part The number of remaining parts in a range of 20% or more of the number may be set as the number of parts for replacement. In this way, for example, since the number of replacement time parts is set with a margin more than using up the accommodating parts, the number of replacement time parts between the accommodating parts can be easily made different. In addition, for example, when the storage portion is a tape or the like for storing components, the remaining tape is relatively long, so that the frequency of processing for adding the excess tape can be further reduced, and the replacement work is accompanied. The efficiency of other work is better. At this time, the setting means may set the number of used parts within a range of 70% or less of the total number of parts of the housing portion or a range of 60% or less as the number of parts for replacement. Alternatively, the setting means may set the number of remaining parts in the range of 30% or more of the total number of parts in the housing portion or in the range of 40% or more as the number of parts for replacement. Further, from the viewpoint of further suppressing an increase in replacement frequency to the spare storage unit, the setting means sets the used component number in the range of 40% or more of the total number of components of the storage unit as the replacement time component number. It is preferable to do. Moreover, it is preferable that a setting means sets the said number of remaining parts of the range of 60% or less of the total number of parts of the said accommodating part to the said number of parts for replacement | exchange time.

  In the support device of the present invention, the setting means is different for the specific storage unit and the other storage units that have the same replacement time determined based on the total number of parts included in the storage unit. The number of parts for each replacement time may be set. By so doing, it is possible to more reliably suppress the overlapping of replacement times. At this time, the setting means, with respect to the specific storage unit and the other storage unit that the same replacement time is determined by the number of mounting per unit time and the total number of components included in the storage unit, The different number of replacement parts may be set. Alternatively, the setting means may include the specific storage unit and the other storage unit that have the same replacement time determined by the mounting time required for the mounting process of one component and the total number of components included in the storage unit. On the other hand, the different numbers of parts for replacement may be set.

  In the support device of the present invention, the setting means acquires a work period including a replacement time of each of the storage units to the spare storage unit based on the set replacement time part number, and the acquired work period It is determined whether or not the work time relating to the replacement to the spare storage unit included in exceeds a predetermined upper limit, and if the work time exceeds the upper limit, the change value is changed again, The replacement time part number may be set. In this way, the work time included in the predetermined work period is within the upper limit value, so that the replacement work can be leveled more reliably. It is preferable to repeat the process of resetting the number of parts for replacement at this time until the work time of the storage section to be replaced does not exceed the upper limit value in all work periods. The “working time included in the predetermined work period” includes, for example, at least one of a time for preparing the spare housing unit to be usable and a time for replacing the housing unit being used and the spare housing unit. It may be a thing. At this time, the setting means has a value larger than the upper limit value when the work time in any work period exceeds the upper limit value even after performing the process of resetting the number of parts for replacement. May be set as a new upper limit value, and it may be determined whether or not the work time exceeds the new upper limit value. In this way, even if the initially set upper limit value is too small and the leveling effect cannot be obtained, the upper limit value is subsequently updated to a large value, so that the leveling effect is finally obtained.

  Alternatively, in the support device of the present invention, the setting unit acquires a work period including a replacement time of each of the storage units to the spare storage unit based on the set replacement time part number, and acquires the work period It is determined whether or not the number of replacements to the spare storage unit included in the work period exceeds a predetermined upper limit value.If the number of replacements exceeds the upper limit value, the change value is changed again, The replacement time part number may be set. In this way, the number of replacements included in the predetermined work period is within the upper limit value, so that the replacement work can be leveled more reliably. Such a process of resetting the number of parts for replacement is preferably repeated until the number of replacements of the storage units to be replaced in all work periods does not exceed the upper limit value. At this time, if the number of replacements in any work period exceeds the upper limit value even after performing the process of resetting the number of parts for replacement, the setting means sets a value larger than the upper limit value. A new upper limit value may be set, and it may be determined whether the number of exchanges exceeds the new upper limit value. In this way, even if the initially set upper limit value is too small and the leveling effect cannot be obtained, the upper limit value is subsequently updated to a large value, so that the leveling effect is finally obtained.

  In the support device according to the aspect of the invention in which the upper limit value is changed, the setting unit adds a multiple of the time required for one worker engaged in the replacement work to replace the spare accommodating unit to the upper limit value. The value may be set to the new upper limit value. In this way, the replacement work can be leveled more reliably by increasing the number of workers.

  The support device according to the present invention indicates that when the number of parts of the specific storage unit reaches the replacement time part number based on the output replacement information, the specific storage unit and the spare storage unit are exchanged. It is good also as a thing provided with the alerting | reporting means which alert | reports alerting | reporting information to an operator. In this way, the operator can grasp, for example, what kind of spare accommodating portion should be replaced and when, for example, based on the notified notification information. Here, for example, the notification unit may notify the worker of the notification information by displaying and displaying a screen, or may notify the worker of the notification information by outputting a voice, The operator may be notified of the notification information by printing out a printed matter.

In the production job data, it is determined in each mounting apparatus 11 which parts from which slot position the feeder is to be mounted in what order on which board type, how many boards are mounted in that order, and the like. It has been.

  In the preparation area A2, as shown in FIG. 1, a work table 80 and a preparatory work computer 90 are provided. The work table 80 is used by the operator in the preparation area A2 to supply (mount) the reel 73 to the empty feeder 72 to produce (prepare) the spare feeder 76. The preparatory work computer 90 includes a computer main body 92, an input device 94, and a display 96, can input signals from the input device 94 operated by an operator, and can output various images to the display 96. is there.

  When the worker in the preparation area A2 produces the spare feeder 76, as shown in FIG. 1, the barcode label 73a affixed to the reel 73 and the barcode label 72a affixed to the feeder 72 to which the reel 73 is mounted. Are read by the label reader of the preparatory work computer 90. Then, the preparatory work computer 90 stores both in association with each other. The barcode of the reel 73 is stored in a database by the management computer 60 in association with the information (type and number of parts) of the parts held on the tape wound around the reel 73 in advance. Therefore, the barcode of the feeder 72 is associated with the information of the parts held on the tape wound around the reel 73 via the barcode of the reel 73. The preparatory work computer 90 can be connected to the storage element 75 of the feeder 72, and the information on the reel 73 is stored in the storage element 75.

  Although not shown, the assembly factory 1 is provided with a warehouse area upstream of the preparation area A2, and further has a loading area upstream thereof. In the arrival area, an identification number (ID) is issued to the new reel 73. The ID of the reel 73 is converted into a barcode, registered by the computer for component registration in the arrival area in association with the information of the component held on the tape wound on the reel 73, and printed on the barcode label 73a. Is done. The printed barcode label 73 a is attached to the reel 73. A plurality of parts shelves are provided in the warehouse area. A large number of reels 73 are arranged and arranged on the parts shelf. The operator selects the reel 73 necessary for replenishment from the parts shelf in the warehouse area and moves it to the preparation area A2.

  Next, the operation of the management computer 60 as the support device of the present embodiment configured as described above, in particular, the replacement time component which is the number of remaining components of the feeder 72 that serves as a guide for replacing the spare feeder 76 and the feeder 72 in use. Processing for outputting information about numbers will be described. FIG. 5 is a flowchart showing an example of a leveling process routine executed by the CPU 62a of the management computer 60. 6A and 6B are conceptual diagrams of the feeder 72 replacement timing. FIG. 6A is a relationship diagram of the feeder replacement timing and working time before the leveling process, and FIG. 6B is each leveling process after the leveling process. FIG. 6 is a relationship diagram of feeder replacement time and work time. The leveling process routine is stored in the HDD 62 c and is executed before the execution of the mounting process on the production line 10 is started. It is assumed that the worker inputs the number of workers on the production line 10 and the number of workers to be reinforced as the amount of work increases in advance to the management computer 60 before executing the leveling process routine.

  When this routine is started, the CPU 62a of the management computer 60 obtains production job data from the HDD 62c (step S100), obtains information such as the total number of parts from the production job data, and calculates part replacement time for each feeder 72. (Step S110). The part-out replacement time is the time required to use up the reel 73, and can be calculated from the number of mountings per unit time or the mounting time per part and the total number of parts. The production job data includes the type of components included in the reel 73 of each feeder 72, the total number of components, the number of components used per board, the transfer time required for mounting at each placement position, and the like. . The CPU 62a calculates the part-out replacement time for each feeder 72 based on these data. For example, in a feeder 72 that accommodates the same number of parts and has the same number of mounted units per unit time, the part breakage replacement time is the same and the replacement time is the same (see feeder Nos. 2 to 4 in FIG. 6A). ). The total number of parts of the feeder 72 is the total number of parts included in the reel 73 when new, and is the value obtained by subtracting the number of consumed parts from the number of parts in a new state when used. The production job data may include the part type and the number of parts that are read out and acquired from each feeder 72 currently mounted on the production line 10. FIG. 6A is an explanatory diagram in the case where the process for obtaining the part replacement replacement time and replacing the spare feeder 76 of the same total number of parts with the feeder 72 is continued. The replacement time when a part is out can be obtained by adding the part out replacement time to the current time.

  Next, the CPU 62a performs processing to extract a feeder having the same part replacement time as a feeder group (step S120), and sets a change value corresponding to each of the feeders 72 included in each feeder group to a different value (step S120). S130). This change value is used to set the number of parts for replacement time, which is the number of remaining parts for notifying the replacement to the spare feeder 76, and is determined as a coefficient (for example, less than 1) by which the total number of parts is multiplied. It has been. For example, the change value may be set to a different value by setting the initial value to 0.10 and adding a predetermined value (for example, 0.05) from the initial value. Specifically, feeder no. 2 is changed to 0.10, and the feeder No. 3 is changed to 0.15, and the feeder No. The change value of 4 may be 0.20.

  Next, the CPU 62a sets the number of parts for replacement corresponding to each feeder 72 using the total number of parts and the change value of the feeder 72 (step S140). The number of parts for replacement time may be set, for example, by multiplying the total number of parts by a change value that is a coefficient. Specifically, feeder no. When 2 to 4 accommodate 10,000 parts and the change values are 0.10, 0.15, and 0.20, respectively, the feeder No. The remaining number of parts for replacement 2 is 1,000. No. 3 replacement period, the remaining number of parts is 1,500, feeder No. The remaining number of parts for 4 is 2,000. For example, as shown in FIG. 6A, in a feeder (Nos. 2 to 4) having the same part replacement time, the replenishment work of the reel 73 and the replacement work with the spare feeder 76 are performed during the same work period. (See work period t4). Here, by changing the change value, the number of parts for replacement time (part replacement time, replacement time) is changed.

  When the replacement time number of parts is set, the CPU 62a calculates the replacement time and working time of all the feeders that have replaced the feeder 72 up to a predetermined number based on the replacement time number of parts (step S150). Here, the CPU 62a calculates a predetermined number (for example, 10 times) of the replacement timing of each feeder 72, assuming that the replacement spare feeder 76 is replaced when the replacement time component count is reached. For example, FIG. A process chart in the mounting apparatus 11 as shown in b) is created. The working time includes a replenishment time (for example, 3 minutes and 6 minutes) required for replenishing the reel 73 to the empty feeder 72 and a replacement time (for example, 2 minutes) required for exchanging the feeder 72 and the spare feeder 76 in use 4 minutes).

  Subsequently, the CPU 62a determines whether or not there is a work period in which the work time exceeds the upper limit value (step S160). The work period may be set based on the replenishment time and the replacement time as one unit (for example, 10 minutes or 30 minutes). The upper limit value may be determined based on, for example, a multiple of the time required for one worker engaged in the replenishment operation and the replacement operation to replenish and replace the spare feeder 76. Specifically, the upper limit value is a product of the time required for one worker to replenish and replace the spare feeder 76 and the number of workers in charge of the replenishment and replacement work, and a predetermined margin if necessary. It may be determined by adding. The upper limit is set according to the number of workers assigned, but is changed according to the change in the number of workers in charge of the production line 10 (see step S190 described later).

  When there is no work period in which the work time exceeds the upper limit value, the CPU 62a considers that the work amount of the worker is appropriate, transmits and outputs the replacement information regarding the set replacement time component number to the mounting apparatus 11, and displays the display. The display is output to 66 (step S170), and this routine is terminated. The replacement information may include, for example, the number of replacement time parts, or may include a change value as information from which the number of replacement time parts can be derived. Shall be included. The mounting controller 50 of the mounting apparatus 11 stores the acquired replacement information in the HDD 53 as the notification timing of the replacement time of each feeder 72, and uses this during the mounting process. As described above, the management computer 60 uses the change value to set a different value for the number of replacement time parts, which is the timing for notifying the replacement to the spare feeder 76. Accordingly, it is possible to disperse the replacement timing of the feeder 72 that will allow the replacement processing to overlap at the same time while intentionally allowing the remaining parts.

  On the other hand, when there is a work period in which the work time exceeds the upper limit value in step S160, the CPU 62a determines whether or not the replacement time part number in step S140 has been set up to a predetermined number of times (step S180). When the number of parts for replacement time has not been set up to a predetermined number of times, the CPU 62a repeatedly executes the processes after step S130. Here, in step S130 at the time of repetition, the change value is further changed so that the difference in the number of parts for replacement of each feeder 72 becomes larger. Specifically, the CPU 62a may change the predetermined value added to the initial value (0.10) to a value larger than 0.05, such as 0.06 or 0.08. Further, the predetermined number of times used for the determination in step S180 may be set to, for example, the number of times determined empirically so that the replacement times of the feeders are appropriately dispersed, for example, 5 times or 10 times. If the working time becomes equal to or less than the upper limit value while setting the number of parts for replacement over a predetermined number of times, the CPU 62a outputs the replacement information in step S170 and ends this routine. On the other hand, when the number of replacement time parts has reached the predetermined number in step S180, it is considered that the work amount of the worker is excessive, and the CPU 62a changes the upper limit value to a larger value (step S190). The processing after step S130 is repeated. Specifically, the CPU 62a sets, as a new upper limit, a value obtained by adding a multiple of the time required for one worker engaged in replenishment and replacement work to replenish and replace the spare feeder 76 to the upper limit. And The larger upper limit value can be set based on, for example, the number of people who can reinforce supply and replacement work. The process of updating the upper limit value is repeated until the work time (replenishment time and replacement time) of the spare feeder 76 does not exceed the upper limit value in all work periods. In step S130 after increasing the upper limit value, the changed value may be returned to the initial value. Then, the upper limit value is changed to a larger value, and if the work time becomes equal to or less than the upper limit value in step S160, the CPU 62a outputs the replacement information in step S170 and ends this routine.

  Here, the leveling process will be described with reference to FIG. Here, the initial value of the upper limit value is set to 10 minutes and the work period is set to 10 minutes, and description will be made assuming that 3 minutes are required for replenishment work for one feeder 72 and 2 minutes are required for replacement work. As shown in FIG. 6 (a), in the feeder 72 having the same part replacement time (for example, 2 hours after the start of mounting), if the replacement timing is set as usual, the operation of each feeder (replenishment work and replacement) Work) overlap in the same work period (work periods t4, t8, t12). In such a case, the management computer 60 sets the number of replacement time parts corresponding to the replacement time to the spare feeder 76 to a value different from that of the other feeders using a change value different from that of the other feeders. For this reason, for example, even in the feeder 72 with the same part replacement time, as shown in FIG. 6B, the time (number of parts to be replaced) for notifying the replacement is appropriately dispersed. The work is moderately distributed.

  Next, an operation of the mounting apparatus 11, for example, a process for executing the mounting process using the exchange information acquired from the management computer 60 will be described. FIG. 7 is a flowchart illustrating an example of a mounting process routine executed by the CPU 51 of the mounting controller 50. This routine is stored in the HDD 53 of the mounting controller 50, and is executed by a start instruction from the operator. This routine is executed by the CPU 51 using each unit of the mounting apparatus 11, for example.

  When this routine is started, the CPU 51 first acquires production job data from the management computer 60 (step S200), and sets the replacement time component number of each feeder 72 using the stored replacement information (step S200). S205). As for the number of parts for replacement, the total number of parts accommodated in each feeder 72 is acquired from each feeder 72, the change value (coefficient) included in the replacement information is acquired, and the total number of parts is multiplied by the coefficient. Can be obtained. When the replacement information includes information on the number of replacement time parts, the CPU 51 can acquire the number of replacement time parts directly from the replacement information. The set replacement time component number is stored in the RAM 54. Next, the CPU 51 executes the conveyance and fixing process of the substrate 16 (step S210), sets the parts to be picked up based on the production job data mounting order (step S220), and performs the picking and placement processes of the parts. This is performed (step S230). In this process, the CPU moves the suction nozzle 40 to a predetermined pickup position of the component supply device 70 and sucks the component. After sucking the component, the CPU 51 moves the suction nozzle 40 to the coordinates of the mounting position specified by the production job data, and places the component on the substrate 16. Next, the CPU 51 updates the number of remaining parts of each feeder 72 and stores it in the RAM 54, and outputs the number of remaining parts to the management computer 60 (step S240).

  Subsequently, the CPU 51 determines whether the number of remaining parts of each feeder 72 has reached the number of replacement time parts set for each feeder (step S250), and the number of remaining parts has reached the number of replacement time parts. When the feeder 72 is present, notification information, which is information indicating that the feeder 72 in use and the spare feeder 76 need to be replaced, is displayed on the operation unit 57 (step S260). This notification information includes the identification number and attachment position of the feeder 72 that requires replacement, the time limit for replacement, and the like. The CPU 51 displays a replacement notification screen including these pieces of information on the display unit 56. The CPU 51 may output the notification information to the management computer 60 or the preparatory work computer 90 and display the notification information on the display 66 or the display 96. Further, the CPU 51 outputs the replacement information and the number of remaining parts to the management computer 60 and the preparatory work computer 90, and these computers execute the process of step S250, and display the replacement notification screen on the display 66 or the display 96. It may be a thing. The worker who has confirmed this replacement notification screen performs the replenishment work and replacement work for the corresponding spare feeder 76.

  After step S260 or when the number of remaining parts has not reached the replacement time part number in step S250, the CPU 51 determines whether or not the current mounting process of the board 16 is completed (step S270). When the mounting process of the substrate 16 is not completed, the processes after step S220 are executed. That is, the CPU 51 sequentially mounts components on the current board 16. On the other hand, when the current mounting process of the board 16 is completed in step S270, the CPU 51 ejects the board 16 that has been mounted (step S280), and determines whether the production is completed (step S290). When the production is not completed, the CPU 51 repeatedly executes the processes after step S210. That is, the CPU 51 transports and fixes a new board 16 and repeats the process of mounting the parts on the board 16 while displaying the notice information (replacement notice screen) when the number of remaining parts reaches the number of parts to be replaced. Do. On the other hand, when the production is completed in step S290, this routine is finished. As described above, when the number of remaining parts reaches the number of parts for replacement time set to a value different from that of the other feeders 72, the mounting apparatus 11 notifies the operator of notification information that prompts replacement work. Even before the operator uses up the feeder 72, the worker performs the notified replacement work of the feeder 72. Note that when the leveling process is performed, the feeder 72 is replaced before the parts are used up, so that an excess tape including the parts is generated. For example, the surplus tape is spliced to a new reel 73 by being connected to another tape with a change in the number of parts. The connected reels 73 are set in the feeder 72 and used for mounting processing.

  Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The feeder 72 (reel 73) of the present embodiment corresponds to a storage portion of the present invention, the spare feeder 76 (reel 73) corresponds to a preliminary storage portion, the component supply device 70 corresponds to a component supply portion, and an X-axis slider. 26, the Y-axis slider 30 and the head 24 correspond to the mounting processing unit, the CPU 62a corresponds to the setting means and the output means, and the operation panel 55 corresponds to the notification means.

  According to the management computer 60 described above, the number of remaining parts of the feeder 72 is set as the number of parts for replacement using the total number of parts included in the specific feeder 72 and a predetermined change value different from that of the other feeders 72. Then, the replacement information regarding the set number of parts for replacement is output to the mounting apparatus 11. Thereafter, the operator is notified of the replacement timing of the feeder 72 by using the output replacement information. As described above, since each feeder 72 has a different replacement time component number for replacement with the spare feeder 76, the replacement time of the spare feeder 76 to be replaced in a certain work period is the same as that of the other spare feeders 76. It becomes difficult to overlap with the replacement time. Therefore, the replacement work of the spare feeder 76 and the feeder 72 in use can be leveled regardless of the time.

  In addition, the CPU 62a replaces the specific feeder 72 and other feeders 72 that have the same replacement time determined by the number of mounted units per unit time and the total number of components included in the feeder 72, with different replacement time parts. Since the number is set, the overlap of the replacement times can be more reliably suppressed. Further, the CPU 62a acquires a work period including the replacement time of each feeder 72 to the spare feeder 76 based on the set replacement time parts number, and the work related to the replacement to the spare feeder 76 included in the acquired work period. It is determined whether or not the time exceeds a predetermined upper limit value. If the work time exceeds the upper limit value, the change value is changed and the number of parts for replacement time is set again. For this reason, since the work time included in the predetermined work period is within the upper limit value, the replacement work can be leveled more reliably. Furthermore, the CPU 62a sets a value larger than the upper limit value to a new upper limit value if the work time in any of the work periods exceeds the upper limit value even after performing the process of resetting the number of parts for replacement. It is set and it is determined whether the work time exceeds a new upper limit value. For this reason, even if the initially set upper limit value is too small and the effect of leveling cannot be obtained, the upper limit value is subsequently updated to a larger value, so that the leveling effect is finally obtained. The CPU 62a sets a value obtained by adding a multiple of the time required for one worker engaged in the replacement work to replace the spare feeder 76 to the upper limit value as a new upper limit value. Therefore, the replacement work can be leveled more reliably. In addition, when the number of remaining parts of the specific feeder 72 reaches the number of replacement time parts, the CPU 62a notifies the operator of notification information that the feeder 72 in use and the spare feeder 76 will be replaced. The person can grasp, for example, what kind of spare feeder 76 should be replaced and when, for example, based on the notified notification information.

  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.

  For example, in the above-described embodiment, the leveling process routine shown in FIG. 5 is executed. However, the present invention is not limited to this as long as the replacement times of the feeders 72 are not overlapped. For example, the CPU 62a may set the change values of the specific feeder 72 and other feeders 72 to different values using random variables. FIG. 8 is a flowchart illustrating an example of another leveling process routine. The leveling process routine is stored in the HDD 62 c and is executed before the execution of the mounting process on the production line 10 is started. When this routine is started, the CPU 62a obtains production job data (step S300), and sets a different change value for each feeder 72 so that the number of remaining parts of each feeder 72 falls within a predetermined range using a random variable. (Step S310). At this time, the CPU 62a may set the predetermined range of the number of remaining parts to a range of 20% to 60% of the total number of parts of the feeder 72. In the range of 20% or more of the total number of parts, for example, the number of replacement time parts is set with more margin than using up the feeder 72, so the number of replacement time parts between the feeders 72 can be easily made different. Further, for example, when the feeder 72 is a tape or the like that accommodates parts, the remaining tape is relatively long, so that the frequency of processing to add the excess tape can be further reduced, and the replacement work is accompanied. The efficiency of other work is better. Moreover, in the range of 60% or more of the total number of parts, the replacement frequency of the feeder 72 can be further suppressed, which is preferable. The predetermined range of the number of remaining parts may be a range of 30% or more of the total number of parts, or a range of 40% or more. The predetermined range of the number of remaining parts may be set empirically in a suitable range depending on the relationship between the frequency of replacement work and the number of splicing processes of the remaining tape. Next, the CPU 62a outputs the set change value to the mounting apparatus 11 as replacement information regarding the number of parts for replacement time (step S320), and ends this routine. The mounting apparatus 11 that acquired the replacement information executes, for example, the above-described execution processing routine, determines whether or not the number of remaining parts has reached the number of parts for replacement at step S250, and displays notification information when it reaches. . When the number of replacement time parts is obtained using the change value set at random as described above, the number of replacement time parts of each feeder 72 is likely to be different as in the case shown in FIG. 6B. Therefore, it is possible to level the exchange work. Further, by using random variables, the replacement work can be leveled with a relatively easy process. Note that even in the above-described embodiment in which random variables are not used, the change value may be set so as to be within the predetermined range.

  In the above-described embodiment, the number of remaining parts remaining in the feeder 72 is set as the number of replacement time parts. However, the present invention is not limited to this, and the number of used parts used in the feeder 72 is set as the number of replacement time parts. It may be set. The same applies to the leveling process of FIG. In the leveling process of FIG. 8, for example, the CPU 62a preferably sets the number of used parts in the range of 80% or less and 40% or more of the total number of parts of the feeder 72 as the predetermined range as the number of replacement time parts. At this time, the predetermined range may be 70% or less or 60% or less of the total number of parts. Even in this case, the same effect as that of the above-described embodiment can be obtained. In this case, the mounting apparatus 11 that has acquired the replacement information executes, for example, the same execution processing routine as described above, and determines whether or not the number of used parts has reached the number of parts for replacement in step S250. What is necessary is just to display alerting | reporting information, when it arrives.

  In the above-described embodiment, the work time included in the specific work period is calculated in step S150, and it is determined whether the work time exceeds the upper limit value in step S160. It may be based on the number of exchanges. Specifically, the CPU 62a acquires a work period including the replacement time of each feeder 72 for the spare feeder 76 based on the set replacement time parts number, and supplies the spare feeder 76 included in the acquired work period. It may be determined whether or not the number of replacements exceeds a predetermined upper limit value, and when the number of replacements exceeds the upper limit value, the change value may be changed and the replacement time component number may be set again. Since the work time related to the replacement of the feeder 72 corresponds to the number of replacements of the feeder 72, the number of replacements included in the predetermined work period is within the upper limit value as in the above-described embodiment, and thus more reliably. Exchange work can be leveled. At this time, if the number of replacements in any work period exceeds the upper limit value even after performing the process of resetting the replacement time component count, the CPU 62a sets a value larger than the upper limit value to the new upper limit value. It may be set to determine whether the number of exchanges exceeds a new upper limit value. In this way, even if the initially set upper limit value is too small and the leveling effect cannot be obtained, the upper limit value is subsequently updated to a large value, so that the leveling effect is finally obtained.

  In the above-described embodiment, it has been described that the feeders 72 with the same part replacement time are extracted and different change values are set for them. It is good also as what extracts and sets a different change value with respect to these. In this way, since different change values are set for the feeders 72 whose replacement timings overlap, this is effective when the leveling process routine is executed during the mounting process. Alternatively, in the above-described embodiment, it has been described that the feeder 72 having the same part replacement time is extracted and different change values are set for these, but this process may be omitted. That is, different change values may be set for all the feeders 72. Even in this case, the replacement work of the spare feeder 76 and the feeder 72 in use can be leveled regardless of the time.

  In the above-described embodiment, the process of updating the upper limit value is repeated until the work time of the spare feeder 76 does not exceed the upper limit value in all work periods. However, the present invention is not limited to this. For example, when the upper limit value is outside the allowable range, the process of increasing the upper limit value may be stopped there, and the last set change value may be adopted, or the work time may be set to the upper limit value set so far. It is good also as what adopts the change value which does not exceed most. Even in this way, the replacement work can be leveled as much as possible.

  In the above-described embodiment, it is determined whether or not the work time included in the predetermined work period exceeds the upper limit value, but the processes in steps S150, S160, and S180 may be omitted. In the above-described embodiment, the upper limit value is increased in step S190. However, this process may be omitted. Even in this case, the replacement work of the spare feeder 76 and the feeder 72 in use can be leveled regardless of the time. Moreover, the processing content can be simplified.

  In the above-described embodiment, the mounting apparatus 11 has been described as repeatedly performing the mounting process using a change value set to a value different from that of the other feeders 72, but the present invention is not particularly limited thereto. For example, the mounting process may be executed using the changed value set to a value different from that of the other feeders 72 only for the first time or the replacement of the feeder 72 from the first time to several times. For example, even if the parts replacement time of the feeder 72 is the same, after the first replacement time is shifted, even if the changed value of each feeder 72 is the same, the first shifted replacement time continues. The replacement work between the spare feeder 76 and the feeder 72 in use can be leveled regardless of the time. In the mounting apparatus 11 described above, after the change value is set to 0.50, when the feeder 72 having a total number of parts of 10,000 is installed in the slot 71, the number of remaining parts reaches 5,000. An exchange is announced. After that, when the feeder 72 having the total number of parts of 5,000 is installed in the slot 71, the replacement is notified when the number of remaining parts reaches 2500. As described above, when the above-described processing is performed, there may be a large difference in the number of remaining parts of the reel 73. On the other hand, if the mounting process is performed using the same change value (for example, a value in the vicinity of the coefficient 1.0) as the other feeders 72 for the second and subsequent replacements, the remaining number of components on the reel 73 Can be made smaller.

  In the above-described embodiment, the notification information is notified on the operation panel 55. However, the notification information is not limited to this. For example, the notification information on the operation panel 55 is assumed to be notified on the display 66 or the display 96. This notification may be omitted. Even in this case, the replacement work of the spare feeder 76 and the feeder 72 in use can be leveled regardless of the time.

  In the embodiment described above, a value obtained by adding a multiple of the time required for one worker engaged in the replacement work to replace the spare feeder 76 to the upper limit value is set as the new upper limit value. As long as the value is largely changed, the present invention is not particularly limited to this.

  In the embodiment described above, the change value is set to a different value by adding the predetermined value (0.05) to the initial value (0.10). It is good also as what is set as a different value between each feeder 72 using a variable. Even in this case, the same effect as that of the above-described embodiment can be obtained. Alternatively, the CPU 62a may acquire a change value set by the operator by input from the input device 64, and set the replacement time component count using this value. Even in this case, the replacement work of the spare feeder 76 and the feeder 72 in use can be leveled regardless of the time.

  In the above-described embodiment, the change value has been described as a coefficient (for example, less than 1) by which the total number of components is multiplied. However, the change value is not particularly limited thereto. In addition, the replacement information includes a change value as information for deriving the number of parts at the time of replacement, but is not particularly limited thereto, and in addition to or instead of this, the number of parts at the time of replacement It may be included. In the above-described embodiment, the component cut-off replacement time is calculated using the number of mountings per unit time. However, the present invention is not limited to this, and the component cut-off replacement time using the mounting time required for mounting a single component is used. May be calculated. In the embodiment described above, the work time includes the supply time for supplying the reel 73 to the spare feeder 76 and the exchange time for exchanging the feeder 72 and the spare feeder 76 in use. It should be included.

  In the above-described embodiment, the feeder 72 mounted with the reel 73 around which the tape for housing the component is mounted has been described as the “accommodating portion”. However, the present invention is not particularly limited thereto. It is good also as. Even in this way, it is possible to level the exchange operation of the accommodating portion.

  In the above-described embodiment, the spare feeder 76 is manufactured by setting the reel 73 on the feeder 72. However, when a compact feeder with a built-in tape take-up unit is used, a tape is fed from the reel to the tape take-up unit. You may produce a preliminary feeder by winding up.

  In the above-described embodiment, the notification information is notified to the worker by displaying and displaying the screen. However, the present invention is not particularly limited thereto, and the notification information may be notified to the worker by outputting a voice. Alternatively, the notification information may be notified to the worker by printing out a printed matter.

  In the above-described embodiment, the leveling process routine is described as being performed before the start of the execution of the mounting process. However, the present invention is not particularly limited thereto, and the leveling process routine may be repeatedly executed every time a predetermined period elapses. . Even in this case, the replacement work of the spare feeder 76 and the feeder 72 in use can be leveled regardless of the time.

  In the above-described embodiment, the management computer 60 has the function of the support device. However, the present invention is not particularly limited thereto. For example, the mounting controller 50 of the mounting device 11 may have the function of the support device. The preparatory work computer 90 may have the function of the support device, and other computers may have the function of the support device. In the above-described embodiment, the management computer 60 has been described as the support device. However, the present invention is not particularly limited thereto, and for example, a support method or a program thereof may be used.
