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,
In the mounting apparatus, the storage unit in use calculates a predicted time when a part will run out, and based on the predicted time, to one or more spare storage units to be replaced in a predetermined work period set before the predicted time An exchange calculation means for calculating the exchange time of
It is determined whether or not the calculated replacement time for the spare storage unit exceeds a predetermined upper limit value, and if it exceeds the upper limit value, any of the preliminary storage units included in the calculated work period is selected as the work A time setting means for performing a pre-replacement process to be replaced in a previous work period that is earlier than the period, and setting a replacement time for the spare container;
Output means for outputting the set replacement time of the preliminary accommodating portion before the replacement time;
It is equipped with.

  In this support apparatus, even if the replacement time of the spare storage unit to be replaced in a certain work period increases as the upper limit value is exceeded, the spare storage to be replaced in the previous previous work period for the portion exceeding the upper limit value Part. 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, the “accommodating portion” may include, for example, a tape that accommodates components, or may include a tray on which components are placed.

  In the support apparatus according to the present invention, the time setting means may set the replacement time of the spare storage unit in consideration of the number of workers and the number of usable storage units. By so doing, the replacement work can be leveled more reliably by taking into account the number of workers and the number of usable storage units.

  In the support device according to the present invention, the time setting means sets a new value larger than the upper limit value when the replacement time in any work period exceeds the upper limit value even after the pre-replacement processing is performed. The upper limit value may be set, and the replacement time of the spare accommodating unit may be set using 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. Such a process of updating the upper limit value is preferably repeated until the replacement time of the accommodating portion to be replaced in all work periods does not exceed the upper limit value. At this time, the time setting means sets, as the new upper limit value, a value obtained by adding a multiple of the time required for one worker engaged in the replacement work to replace the spare accommodating portion to the upper limit value. It may be a thing. In this way, the replacement work can be leveled more reliably by increasing the number of workers.

  In the support apparatus according to the present invention, the time setting means may be replaced at a more distant position in the accommodating portion in use that is replaced in the work period in the mounting apparatus when the pre-replacement processing is performed. The storage section should be replaced in the previous work period, or the spare storage section replaced at a position closer to the used storage section to be replaced in the mounting apparatus in the previous work period is replaced in the previous work period. It is good also as what should set the replacement | exchange time of the said preliminary | backup accommodating part by at least one among them. If it carries out like this, a worker's movement by exchange work can be controlled more, and exchange work can be leveled, accompanied by more efficient exchange work.

  The support device according to the present invention is the support device according to any one of the above-described ones that also supports a preparatory work for supplying parts to the spare container, and based on the calculated predicted time, before the predicted time. Replenishment calculating means for calculating the replenishment time of one or more spare storage units to be replenished during a predetermined work period to be set, and the time setting means is a predetermined upper limit for the replenishment time of the preliminary storage unit It is determined whether or not the value exceeds the upper limit value, and if it exceeds the upper limit value, any one of the spare storage units included in the calculated work period should be replenished in the work period prior to the work period. And setting the replenishment time of the spare storage unit before the set replacement time of the spare storage unit, and the output means also outputs the set replenishment time of the preliminary storage unit There. In this way, it is possible to level the preparation work for replenishment of the spare storage section and level the replacement work. In addition, since the work schedule is assigned so that the replacement work of the spare storage unit is performed after the replenishment work, the replacement work can be leveled more reliably.

  In the support device of the present invention including a replenishment calculating means, the timing setting means includes as much as possible replenishment work of the preliminary accommodating portion in the work period when performing the pre-replacement process and the pre-replacement process. The replacement period and the replenishment time of the preliminary accommodating part may be set by at least one of the replacement work of the spare accommodating part as much as possible in the work period. In this way, the worker is assigned a work schedule in which either the replenishment work or the replacement work is arranged during the same work period, so that the replenishment work and the replacement work are leveled and more efficient work is performed. It can be carried out.

  In the support device according to the aspect of the invention including the replenishment calculation unit, the time setting unit includes a total time obtained by adding the replenishment time of the spare storage unit and the replacement time of the spare storage unit included in the predetermined work period. It is determined whether or not a predetermined upper limit value is exceeded, and if it exceeds the upper limit value, any of the spare storage units exceeding the upper limit value should be replenished or replaced in a previous work period prior to that As an alternative, the replacement time and / or the replenishment time may be set. In this way, the replenishment work and the replacement work can be leveled using the total time of the replenishment work and the replacement work performed during the same work period.

  The support apparatus according to the present invention may include a notification unit that notifies the worker of the output replacement time. In this way, the operator can grasp, for example, what kind of spare accommodating portion should be prepared and when, based on the notified replacement time. Here, the notification means may notify the worker of the output replenishment time. Further, the notifying means may notify the worker of the replacement time or the replenishment time by, for example, displaying a screen, or notify the worker of the replacement time or the replenishment time by outputting a sound. Alternatively, the operator may be notified of the replacement time or the replenishment time by printing out the printed matter.

The head 24 moves in the left-right direction as the X-axis slider 26 moves in the left-right direction along the guide rails 28, 28, and the Y-axis slider 30 moves in the front-rear direction along the guide rails 32, 32. As it moves, it moves in the front-rear direction. The suction nozzle 40 uses pressure to suck a component at the tip of the nozzle or to release a component sucked at the tip of the nozzle. The height of the suction nozzle 40 is adjusted by a Z-axis motor 34 built in the head 24 and a ball screw 36 extending along the Z-axis. The component supply device 70 has a plurality of slots 71 arranged in the left-right direction, and a feeder 72 can be inserted into each slot 71. A reel 73 around which a tape is wound is attached to the feeder 72. On the surface of the tape, parts are held in a state of being arranged at equal intervals along the longitudinal direction of the tape. These parts are protected by a film covering the surface of the tape. Such a tape is fed by a predetermined pitch by a sprocket 74 shown in FIG. 3, and is placed at a predetermined position in a state where the film is peeled off and the parts are exposed. The components arranged at the predetermined positions are sucked by the suction nozzle 40. The mounting controller 50 is configured as a microprocessor centered on a CPU, and is connected so that signals can be exchanged with the substrate transport device 18, the X-axis slider 26, the Y-axis slider 30, the head 24, and the component supply device 70. Has been. The mounting apparatus 11 is provided with an operation panel (not shown), and displays information related to the feeder 72 to be replaced in the next work period on a display (not shown).

  The management computer 60 has the function of the support apparatus of the present invention, and includes a computer main body 62, an input device 64, and a display 66, as shown in FIGS. As shown in FIG. 4, the computer main body 62 is configured as a microprocessor centered on a CPU 62a, and includes a ROM 62b for storing processing programs, an HDD 62c for storing various data, a RAM 62d used as a work area, an external device and an electric device. An input / output interface 62e for exchanging signals is provided. These are connected via a bus 62f. Further, the computer main body 62 is connected to a mouse and a keyboard which are input devices 64 via an input / output interface 62e and a display 66 which is an output device. Further, the computer main body 62 is connected to the LAN via the input / output interface 62e and the communication device 68, and is capable of bidirectional communication with the preparatory work computer 90. The HDD 62c of the computer main body 62 stores production job data including information on mounting conditions. 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. A mouse, a keyboard, and a label reader (here, a barcode reader) are connected to the input device 94. The preparatory work computer 90 displays on the display 96 information related to the spare feeder 76 to be replenished with the reel 73 mounted on the empty feeder 72.

  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.

  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 mounting apparatus 11 will be described. When the mounting controller 50 of the mounting apparatus 11 receives a command to start mounting components on the board 16, the sprocket 74 of the feeder 72 is rotationally driven to unwind the tape wound around the reel 73 toward the rear, The part is exposed on the surface of the tape at a predetermined position. Thereafter, the mounting controller 50 controls the X-axis slider 26 and the Y-axis slider 30 so that the suction nozzle 40 comes directly above the exposed component. Subsequently, the mounting controller 50 controls the Z-axis motor 34 to lower the suction nozzle 40 with the ball screw 36 and applies a negative pressure to the suction nozzle 40. Then, the component is adsorbed to the adsorption nozzle 40. Thereafter, the mounting controller 50 raises the suction nozzle 40, controls each slider 26, 30 so that the component is directly above a predetermined position of the substrate 16, lowers the suction nozzle 40 at that position, and sucks the suction nozzle 40. Supply positive pressure to Then, the component leaves the suction nozzle 40 and the electronic component is mounted at a predetermined position on the substrate 16.

  Next, the operation of the management computer 60 as the support device of the present embodiment configured as described above, in particular, the replenishment time when the empty feeder 72 is replenished with the reel 73 and the spare feeder 76 is prepared, and the spare feeder 76 is in use. A process for outputting the replacement time with the feeder 72 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 replacement timing of the feeder 72. FIG. 6A is an explanatory diagram before the pre-replacement process, and FIG. 6B is an explanatory diagram after the pre-replacement process. FIG. 7 is an explanatory view of the outline of the leveling process, FIG. 7A is an explanatory view of the attachment position of the feeder 72 on the production line 10, and FIGS. 7B to 7I are the leveling process. It is explanatory drawing of a series of processes. The leveling process routine is stored in the HDD 62c, and is repeatedly executed every elapse of a predetermined time (for example, 30 minutes or 1 hour) with the execution of the mounting process in the production line 10. 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 acquires production job data from the HDD 62c (step S100), and calculates an expected time when the parts of each feeder 72 mounted on the production line 10 will run out (step S110). ). 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. . Based on these data, the CPU 62a can calculate the expected time when the parts of each feeder will run out. For example, the expected time of out of parts can be obtained by dividing the number of parts accommodated in the feeder by the number of parts used per board and multiplying that value by the cycle time. The number of parts accommodated in the feeder is the total number of parts when it is new, and is a value obtained by subtracting the number of parts consumed from the number of parts in a new state when used. The cycle time is the time required to mount all the components on one board, and may be calculated by the CPU 62a immediately before executing the leveling process routine. 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. Further, the expected time of part shortage can be obtained by adding the expected time of part shortage to the current time. FIG. 6A is an explanatory diagram in which the estimated time of component shortage is obtained in this way.

  Next, the CPU 62a sets a predetermined determination period for performing the replenishment work for replenishing the empty feeder 72 with the reel 73 in advance and preparing the spare feeder 76 and the exchange work for exchanging the feeder 72 and the spare feeder 76 in use. (Step S120). This determination period includes one or more predetermined work periods, and may be, for example, a preset time (30 minutes, 1 hour, etc.). Alternatively, since the replenishment time and the replacement time may be changed by a pre-replenishment advancement process or a pre-replacement advancement process, which will be described later, the determination period is dynamically determined so that the replacement time of each feeder 72 is included only once by the CPU 62a. It is good also as what is set to (refer Fig.6 (a)). The pre-replenishment advancement process is a replenishment work of the reel 73 to the empty feeder 72 during a work period (also referred to as a previous work period) prior to the initial work period including the replenishment time obtained based on the part cut-off time. This is a process for setting the time to perform. Further, the pre-replacement processing is to replace the feeder 72 currently in use with the spare feeder 76 during the work period (previous work period) before the initial work period including the replacement time obtained based on the part cut-off time. This is a process for setting the timing for performing the work to be performed.

  When the determination period is set, the CPU 62a selects a determination target work period for determining whether to execute the pre-replenishment advancement process or the replacement advancement process (step S130). In this process, among the one or more work periods included in the determination period, the work periods are selected in order from the later period. The work period includes, for example, a time required for replenishing the reel 73 to the empty feeder 72 (for example, 3 minutes or 6 minutes), a time required for exchanging the feeder 72 in use with the spare feeder 76 (for example, 2 minutes, 4 minutes or the like) may be set based on these (for example, 5 minutes or 10 minutes). Next, the CPU 62a sets a predetermined upper limit value for determining whether to execute the pre-replenishment advance process or the pre-replacement advance process (step S140). 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 value is set according to the number of workers assigned, but is changed according to a change in the number of workers in charge of the production line 10.

  When the upper limit value is set, the CPU 62a calculates the total time obtained by adding the replenishment time and the replacement time of the feeder 72 included in the selected work period (step S150), and whether the calculated total time exceeds the upper limit value. It is determined whether or not (step S160). Here, the CPU 62a obtains the replacement time of each feeder 72 by adding the expected part cut time to the time, grasps the feeder 72 having the replacement time included in this work period, and supplies and replaces during this work period. Assume that the total time is calculated as a work. When the total time does not exceed the upper limit value, the CPU 62a considers that the amount of work of the worker is appropriate, and does not execute the pre-replenishment advancement process or the pre-replacement advancement process. It is determined whether or not the above determination has been made for the work period (step S220). When the above determination is not made for all the work periods, the CPU 62a executes the processes after step S130. That is, in step S130, the CPU 62a selects the previous work period as the work period to be determined, and then in step S160, determines whether the total time exceeds the upper limit value.

  On the other hand, when the total time exceeds the upper limit value in step S160, the CPU 62a considers that the work amount of the worker is excessive, and whether or not advance processing including pre-replenishment processing and forward replacement processing is possible. Is determined (step S170). In this determination, the CPU 62a advances the process when the work period immediately before the selected work period is the foremost work period included in the determination period, and when the advance process is performed, the total time exceeds the upper limit value. Is not possible, and in other cases, advance processing is possible. When the advance processing is possible, the CPU 62a determines whether or not the replenishment work is included in the selected work period (step S180). When replenishment work is included in the selected work period, the CPU 62a performs a pre-replenishment process in which any one of the feeders 72 included in the selected work period is to be replenished in the work period prior thereto. The replenishment time of the spare feeder 76 is set (step S190). Here, the CPU 62a selects the replenishment work of the feeder 72 at a farther replacement position included in the selected work period, and performs a process of moving to the previous work period. In this way, the work period being selected further includes the replenishment work of the feeder 72 that needs to be replaced, which is in a closer replacement position. Further, since the replenishment work is prioritized and advanced, the replacement work of the feeder 72 is further included in the selected work period. In the process of selecting a feeder 72 at a farther exchange position, for example, the CPU 62a determines one feeder 72 and repeats the process of obtaining the distance of another feeder with respect to this feeder 72 for each feeder, and a group of feeders. Assume that the feeder 72 having the exchange position farthest from 72 is selected. At this time, the CPU 62a has a plurality of feeders 72 that are not superior to the distance of the replacement position with respect to the group of feeders among the plurality of feeders 72. May select one feeder based on a predetermined superiority or inferiority order (for example, feeder number order). Here, it is assumed that the CPU 62a selects in order from the smallest feeder number.

  On the other hand, in step S180, when the replenishment work is not included in the selected work period, for example, when all the replenishment work is advanced, the CPU 62a selects one of the feeders 72 included in the selected work period. Pre-replacement processing that should be replaced in the previous work period is performed, and the replacement time for the spare feeder 76 is set (step S200). At this time, the CPU 62a selects a replacement work of the feeder 72 at a further replacement position included in the selected work period, and performs a process of moving to the previous work period. Selection of the feeder 72 at a farther exchange position can be performed by the same method as in step S190. In this way, the work period being selected further includes the replacement work of the feeder 72 that needs to be replaced at a closer replacement position. Here, in order to move the replenishment work more preferentially to the previous work period, a work schedule is assigned in the specific spare feeder 76 so that the spare storage unit is replaced after the replenishment work.

  After step S200 or step S190, the CPU 62a repeatedly executes the processing after step S150. That is, in step S150, the total time after the replenishment advance processing is calculated, and in step S160, it is determined whether or not the total time exceeds the upper limit value. If the total time exceeds the upper limit value, the pre-replenishment advancement process or processing in step S190 or the pre-replacement process in step S200 is executed. In addition, for the replenishment work and replacement work of the spare feeder 76 that has not been advanced, the replenishment time and replacement time are set in the work period initially included. As described above, the CPU 62a performs the replenishment work and the replacement work for each feeder 72 so that the replenishment time and the replacement time (total time) included in the selected work period are equal to or less than the upper limit values at which the worker can work. The time to be performed is set using advance processing.

  On the other hand, when advance processing is not possible in step S170, that is, when the total time (working time) during the work period included in the determination period does not become the upper limit value or less, the CPU 62a has been set in the set determination period. The replenishment time and replacement time are cleared (step S210), and the processing after step S130 is executed. That is, in step S130, the determination target work period is set, and in step S140, the upper limit value used for the determination is reset. In the process of step S140 when the advance process is not possible, the CPU 62a sets the upper limit value that is larger than the currently set upper limit value. 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 time required for replenishment and replacement of the feeder 72 to be replenished and replaced in all work periods does not exceed the upper limit value.

  When the above determination is made for all the work periods included in the determination period in step S220, the CPU 62a sets the timing (work time) of the replenishment process and replacement process of the feeder 72 for all the determination periods. It is determined whether or not it has been set (step S230), and when the work time has not been set for all the determination periods, the processing after step S120 is executed. That is, the CPU 62a sets the next determination period in step S120, selects the last work period included in the determination period as a determination target in step S130, and as necessary until the total time does not exceed the upper limit value. Pre-replenishment processing and pre-replacement processing are performed. On the other hand, when the work time is set for all the determination periods in step S230, the CPU 62a outputs time information including the set replenishment time and replacement time to the mounting apparatus 11, the preparatory work computer 90, and the display 66. (Step S240), this routine is finished. This time information includes, for example, information on the feeder 72 (identification information, etc.), information on the part type, information on the replenishment time and replacement time, as information on the spare feeder 76 that requires replenishment and replacement. The worker confirms the time information displayed on the operation panel of the mounting apparatus 11, the display 96 of the preparatory work computer 90, and the display 66 to determine which spare feeder 76 should be prepared and replaced at which time. I can grasp it.

  Next, a specific example of the leveling process routine will be described with reference to the schematic explanatory diagram of FIGS. Here, it is assumed that the determination period is set to 30 minutes and once, the initial value of the upper limit is set to 5 minutes, the work period is set to 5 minutes, 3 minutes for replenishment work, 2 minutes for replacement work It will be explained as necessary. Further, in this production line 10, as shown in FIG. 1 and 5 are mounted, and the feeder No. 2 is mounted, and feeders Nos. 3 and 4 are mounted on the mounting apparatus 11d. When the leveling process routine is executed, the CPU 62a calculates an expected time at which each feeder will run out of parts in step S110 (see FIG. 6A). Here, the feeder No. 1 is the time included in the work period t3, the feeder No. 2 to 4 are times included in the work period t5, feeder No. It is assumed that 5 is out of parts at the time included in the work period t6 (FIG. 7B). Next, the CPU 62a sets the determination period to a predetermined period (here, 30 minutes) in step S120, and first, in step S130, the work period t6 that is the last of the determination periods is set as the determination target work period. Select. Next, the CPU 62a sets an upper limit value in step S140, calculates the total time in the work period to be determined in step S150, and determines whether or not the total time exceeds the upper limit value in step S160. During the work period t6, the feeder No. Since the replenishment and replacement work of only 5 is included, the CPU 62a determines that the total time does not exceed the upper limit value, and selects the previous work period t5 in step S130.

  Next, the CPU 62a calculates the total time in the work period t5 and determines whether or not the total time exceeds the upper limit value. In the work period t5, the feeder No. Since 2 to 4 replenishment and replacement operations are included, the CPU 62a determines that the total time exceeds the upper limit value, and determines whether advance processing is possible. Since the work period t4 is not the foremost work period, the CPU 62a determines that the advancement process is possible and determines whether or not there is a replenishment work in the work period t5. Next, the CPU 62a determines that there is a replenishment operation during the operation period t5, and selects a feeder located at a farther replacement position. Here, the feeder No. 2 to 4, the furthest feeder No. 2 is selected (see FIG. 7A). Subsequently, the CPU 62a determines the selected farthest feeder No. 2 to advance the replenishment work ahead of the feeder No. 2 is set to the work period t4 (FIG. 7C). The CPU 62a repeats the pre-supply replenishment process until the total time becomes equal to or less than the upper limit value (FIGS. 7D and 7E). When the total time exceeds the upper limit value and the replenishment work is not included in the work period, the CPU 62a determines that the feeder No. No. 2 is moved forward and feeder no. 2 is set to the work period t4. Then, the CPU 62a determines that the total time of the work period t5 does not exceed the upper limit value, and in the work period t5, the feeder No. Only the replacement work of 3 and 4 is included (FIG. 7 (f)). Subsequently, the CPU 62a selects the work period t4 as a determination target in step S130. The CPU 62a repeats the same process as described above, performs a process of moving the replacement position farther away and prioritizing the replenishment work, and the feeder No. No. 4 replenishment work and feeder no. 2 replacement work is included (FIG. 7G). Similarly, the CPU 62a performs forward processing for the work periods t3 to t1, and the feeder No. No. 3 replenishment work and feeder no. 1 is included (FIG. 7 (h)), and the feeder No. 2, 1 replenishment work is included (FIG. 7 (i)). Then, when viewed over the entire determination period, as shown in FIG. The replacement work of No. 2 is put forward, and feeder no. The replenishment work of 1-4 is advanced. As described above, the CPU 62a sets a work schedule in which the work time of the replenishment work and the replacement work is within the upper limit value in each work period included in the determination period. In addition, when the replacement process is advanced, the feeder 72 is replaced before the parts are used up, so that an excessive tape including the parts is generated. This tape can be used by, for example, performing a splicing operation for joining to another tape with a change in the number of parts.

  Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The management computer 60 of the present embodiment corresponds to the support device of the present invention, the computer main body 62 of the management computer 60 corresponds to the replacement calculation means, the timing setting means, the supply calculation means, and the output means, and the display 66 corresponds to the notification means. To do. Further, the component supply device 70 corresponds to a component supply unit, the feeder 72 (reel 73) corresponds to a storage unit, the spare feeder 76 corresponds to a backup storage unit, and the head 24, the X-axis slider 26, and the Y-axis slider 30. Etc. corresponds to the mounting processing unit.

  According to the management computer 60 (support device) of the present embodiment described in detail above, the expected time when the feeder 72 (accommodating portion) in use in the mounting apparatus 11 will run out of parts is calculated, and the expected time is calculated based on the expected time. The replacement time for one or more spare feeders 76 to be replaced in a predetermined work period set before is calculated, and if the calculated replacement time for the spare feeder 76 exceeds a predetermined upper limit value, the upper limit value is set. Pre-replacement processing is performed in which any of the surplus spare feeders 76 should be replaced in the previous work period before that, and the replacement time of the spare feeder 76 is set. Then, the set replacement time of the spare feeder 76 is output before this replacement time, and the operator is notified. In this management computer 60, even if the replacement time of the spare feeder 76 to be replaced in a certain work period increases as the upper limit value is exceeded, the portion exceeding the upper limit value is reserved in the previous previous work period. Since the feeder 76 is used, the replacement work of the spare feeder 76 and the feeder 72 in use can be leveled regardless of the time.

  In addition, when the replacement time in any work period exceeds the upper limit value even after performing the pre-replacement process, the management computer 60 sets a value larger than the upper limit value as a new upper limit value and sets a new upper limit value. The replacement time of the spare feeder 76 is set using the upper limit value, that is, the replacement time of the spare feeder 76 is set in consideration of the number of workers. For this reason, it is possible to level the replacement work more reliably by taking into account the number of workers. 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 larger value, so that the leveling effect is finally obtained. In addition, since a value obtained by adding a multiple of the time required for one worker to replace the spare feeder 76 is set as a new upper limit value, the number of workers is increased, for example, and the replacement work is leveled more reliably. can do.

  Furthermore, when performing the pre-replacement processing, the management computer 60 should replace the spare feeder 76 that is exchanged at a further exchange position among the feeders 72 in use that are exchanged in the work period in the mounting apparatus 11 in the previous work period. Therefore, the movement of the operator during the replacement work can be further suppressed, and the replacement work can be leveled with more efficient replacement work. Furthermore, if the calculated replenishment time of the spare feeder 76 exceeds a predetermined upper limit value, the management computer 60 should replenish any of the spare feeders 76 that have exceeded the upper limit value in the previous work period. In order to set the supply time of the spare feeder 76 before the set replacement time of the spare feeder 76, the preparatory work for supplying the spare feeder 76 is leveled and the replacement work is leveled. can do. Further, since the management computer 60 is assigned a work schedule so that the replacement work of the spare feeder 76 is performed after the replenishment work, the replacement work can be leveled more reliably.

  Then, when performing the pre-replacement process and the pre-replenishment process, the management computer 60 includes the replenishment process of the spare feeder 76 in the work period as much as possible by performing the advance process with higher priority on the replenishment process. The replacement time and the replenishment time of the spare feeder 76 are set by at least one of the replacement operations of 76 as much as possible. For this reason, the worker is assigned a work schedule in which either the replenishment work or the replacement work is arranged during the same work period, so that the replenishment work and the replacement work are leveled and more efficient work is performed. be able to.

  Further, the management computer 60 exceeds the upper limit value when the total time including the replenishment time of the spare feeder 76 and the replacement time of the spare feeder 76 included in the predetermined work period exceeds a predetermined upper limit value. Any of the spare feeders 76 should be replenished or replaced in a previous work period prior to that. For this reason, it is possible to level the replenishment work and the replacement work using the total time of the replenishment work and the replacement work performed during the same work period.

  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 embodiment described above, the CPU 62a sets the replenishment time and replacement time of the spare feeder 76 in consideration of the number of workers. For example, the CPU 62a takes into account the number of empty feeders 72 that can be used. The replenishment time and replacement time of the feeder 76 may be set. In considering the number of empty feeders 72, the CPU 62a manages the number of empty feeders 72, obtains the replenishment timing and the number of empty feeders 72 used in the replenishment work, and can secure the empty feeders 72. After confirming that there is, it is also possible to perform a pre-replenishment advancement process or a replacement advancement process. In this way, the replacement work can be leveled more reliably by taking into account the number of usable feeders 72. When there is no empty feeder 72 that can be used for replenishment work, an increase in the work amount can be dealt with by increasing the upper limit value. Alternatively, in the above-described embodiment, the supply time and replacement time of the spare feeder 76 are set in consideration of the number of workers, but this may be omitted. Even in this way, the leveling of the replenishment work and replacement work of the spare feeder 76 can be performed.

  In the embodiment described above, the CPU 62a sets a value obtained by adding, to the upper limit, a multiple of the time required for one worker engaged in the replenishment work or replacement work to replenish or replace the spare feeder 76. However, the present invention is not limited to this. For example, the CPU 62a increases the upper limit value by a predetermined time (for example, 3 minutes or 5 minutes) and replenishes the preparation area A1 with the number of workers commensurate with the upper limit value at the time when the leveling process routine ends. It is good also as what notifies an operator.

  In the above-described embodiment, the CPU 62a performs the advance processing of the replenishment work timing of the spare feeder 76 included in the work period and the advance processing of the replacement work time of the spare feeder 76. However, the present invention is particularly limited to this. For example, the replenishment work and the replacement work may be managed by separate work schedules, and the pre-replenishment advancement process and the replacement advancement process may be performed separately. FIG. 8 is an explanatory diagram of an outline of the leveling process in which the replenishment work and the replacement work are divided, in which FIG. 8A is an explanatory diagram before the forward processing and FIG. 8B is an explanatory diagram after the forward processing. As shown in the upper part of FIG. 8, the CPU 62a calculates the replenishment time included in each work period. When the replenishment time exceeds the upper limit value, the CPU 62a performs the replenishment work for any of the spare feeders 76 included in the work period. The replenishment process is performed to set the replenishment time of the spare feeder 76. Similarly, as shown in the lower part of FIG. 8, the CPU 62a calculates the replacement time included in each work period, and when the replacement time exceeds the upper limit value, any of the spare feeders 76 included in the work period. The replacement work is advanced and the replacement time of the spare feeder 76 is set. At this time, the replenishment time and the replacement time are set so that the replenishment time comes before the replacement time of one spare feeder. Even in this way, the replenishment work and replacement work of the spare feeder 76 can be leveled.

  In the above-described embodiment, the CPU 62a performs the pre-replenishment processing of the spare feeder 76 and the pre-replacement processing. However, for example, the pre-replenishment processing may be omitted. Even in this case, the replacement work of the spare feeder 76 containing the parts and the feeder 72 in use can be leveled regardless of the time. At this time, the replenishment work of the spare feeder 76 that performs the pre-replacement process may be performed in advance before the replacement work. Alternatively, the pre-replacement advancement process may be omitted from the replenishment advancement process and the replacement advancement process. In this way, it is possible to level the replenishment work of the spare feeder 76 (spare accommodating portion) that accommodates the parts regardless of the time.

  In the above-described embodiment, the CPU 62a has been described as performing replacement advance processing in which the spare feeder 76 to be replaced at a more remote replacement position among the feeders 72 in use to be replaced should be replaced in the previous work period. However, it is not particularly limited to this. For example, when performing the pre-replacement processing, the CPU 62a may replace the spare feeder 76 that is replaced at a position closer to the feeder 72 in use that is replaced in the previous work period in the mounting apparatus 11 in the previous work period. Good. In this way, the CPU 62a can further suppress the movement of the operator in the replacement work, and can level the replacement work with more efficient replacement work. Alternatively, the CPU 62a preliminarily replaces the spare feeder 76 to be replaced at a replacement position that is farther away from the feeder 72 in use to be replaced. However, the CPU 62a performs the advance replacement process without considering the distance of the replacement position. It may be a thing. In this way, the replacement work can be leveled while further suppressing the complication of the processing contents.

  In the above-described embodiment, the CPU 62a has been described as performing the replenishment advance processing in which the spare feeder 76 that is to be replaced at a more remote replacement position among the feeders 72 that are being used to be replaced should be replenished in the previous work period. However, it is not particularly limited to this. For example, when performing the pre-replenishment processing, the CPU 62a may replenish the preliminary feeder 76 that is replaced at a position closer to the feeder 72 in use that is replaced in the previous work period in the mounting apparatus 11 in the previous work period. Good. 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. Alternatively, the CPU 62a performs the pre-replenishment processing of the spare feeder 76 to be replaced at a further replacement position among the feeders 72 in use to be replaced, but performs the pre-replenishment processing without considering the distance of the replacement position. It may be a thing.

  In the above-described embodiment, the CPU 62a is described as including the replenishment process and the replacement process in the same work period in the initial state, but the present invention is not particularly limited thereto. FIG. 9 is an explanatory diagram for setting the replacement process to be performed in the work period after the replenishment process. For example, as shown in FIG. 9, the CPU 62a may include the replenishment work in a period before the work period in which the replacement work is performed before performing the advance processing. In this way, the replacement work of the spare feeder 76 can be performed more reliably. Further, as shown in FIG. 9, the CPU 62a may include the replacement work in a work period before the calculated replacement time. By doing this, although there is a surplus of components on the reel 73, it is possible to further suppress the interruption of the mounting process of the mounting apparatus 11 and perform a more continuous mounting process.

  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 replenishment operation and the replacement operation of the storage section.

  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 operator is notified of the replenishment time and replacement time of the spare feeder 76 by displaying and displaying a screen. However, the present invention is not limited to this as long as the replenishment time and replacement time are notified. . For example, the operator may be notified of the supply time or replacement time by outputting a sound, or the printed material may be printed to notify the worker of the supply time or replacement time.

  In the above-described embodiment, the leveling process routine is repeatedly executed every time a predetermined period is accompanied with the execution of the mounting process. However, the present invention is not limited to this, and the leveling process routine is executed before the mounting process is executed. It is also possible to set the supply time and replacement time of the spare feeder 76 throughout the entire production. 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 replenishment time and replacement time of the spare feeder 76 are calculated. However, the present invention is not particularly limited to this. For example, the number of spare feeders 76 that require work is set as the replenishment time and replacement time of the spare feeder 76. It is also possible to perform the pre-replenishment advancement process or the pre-replacement advancement process depending on whether or not the upper limit (the number of spare feeders 76) is exceeded. Even in this case, the replacement work between the spare feeder 76 and the feeder 72 in use and the replenishment work of the spare feeder 76 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.

  The present invention is used to support an operation of preparing a component to be replenished in an assembly factory for mounting a component on a board.
