Description

The present invention aims to improve production efficiency when arranging an automatic feeder device and a manual feeder device at a plurality of arrangement positions arranged in a row on a component mounting machine, and sets a plurality of component types into the automatic feeder device and the manual feeder device. The present invention relates to a part type allocation method and a part type allocation device to be allocated to a manual feeder device.

Facilities for producing substrates on which a large number of components are mounted include solder printing machines, component mounting machines, reflow machines, and board inspection machines. It has become common to connect these facilities to form a substrate production line. Of these, the component mounting machine includes a board transfer device, a component supply device, a component transfer device, and a control device. As a typical example of the parts supply device, there is a feeder device of a type in which parts storage tapes containing parts are fed out to a plurality of parts storage units. In combination with this feeder device, a reel holding device is used that holds the parts supply reel around which the parts storage tape is wound in a rotatable and replaceable manner.

The plurality of feeder devices and reel holding devices are arranged at a plurality of arrangement positions arranged in a row on the component mounting machine. Then, the plurality of component types of the components to be mounted on the substrate are arranged at a plurality of arranged arrangement positions. At this time, the production efficiency of the substrate changes depending on the order in which the plurality of component types are arranged. Therefore, a technique for simulating the arrangement of component types has been developed in consideration of the moving distance of the mounting head of the component transfer device, and an example is disclosed in Patent Document 1. In the device layout determining method of Patent Document 1, the management device determines the layout of a plurality of feeder devices so that the mounting cycle time (tact time) required to produce one substrate is shortened. At this time, the difference in the types of the plurality of feeder devices, the conditions of the parts types that can be supplied, and the like are taken into consideration (see paragraphs 0026 and 0027 of Patent Document 1).

JP-A-2009-130337

By the way, when the parts stored in the parts storage tape in the conventional manual feeder device are exhausted during the production of the board, a splicing operation for replenishing and connecting a new parts storage tape is required. The splicing work is troublesome for the worker because it takes time and effort, and is one of the causes for lowering the production efficiency. As a countermeasure against this, an automatic feeder device (so-called autoloading feeder) has been developed, which has an automatic loading function for automatically loading a component storage tape and greatly reduces splicing work.

In contrast to the recent development trend of the feeder device described above, the technique of Patent Document 1 does not consider the difference in workability between the automatic feeder device and the manual feeder device. That is, in the technique of Patent Document 1, although the direct mounting cycle time for executing the production of the substrate can be shortened, the splicing work cannot be reduced, and the overall production efficiency including the splicing work time can be improved. difficult. From another point of view, establish a method for allocating parts to the automatic feeder device and the manual feeder device so that the automatic feeder device, which has good workability and is highly convenient when refilling the component storage tape, can be effectively used. It is necessary.

The present invention has been made in view of the above-mentioned problems of the background technology, and is a method of allocating parts types that can effectively utilize an automatic feeder device to reduce splicing work and contribute to improvement of substrate production efficiency. And the problem to be solved is to provide the parts type allocation device.

The component type allocation method of the present invention that solves the above problems is an automatic feeder device having an automatic loading function that automatically loads the component storage tape when the component storage tapes containing the components are inserted into the plurality of component storage sections. And a part type allocation method that allocates a plurality of part types to a manual feeder device that does not have an automatic loading function, and a new part is used when there are no more parts stored in the parts storage tape loaded in the manual feeder device. A workability evaluation step that evaluates the amount of time and effort required for splicing work to replenish and connect the storage tape for each part type of the part, and a part type that requires a large amount of time and effort for the splicing work are preferentially allocated to the automatic feeder device. It has an automatic side allocation step.

In the part type allocation method of the present invention, the amount of time and effort required for splicing work in the manual feeder device is evaluated, and the part type that requires a large amount of time and effort for splicing work is preferentially allocated to the automatic feeder device. Therefore, the automatic feeder device can be preferentially used over the manual feeder device, and the automatic feeder device can be effectively utilized to reduce the splicing work. Further, since the labor of the splicing work in the manual feeder device is reduced in descending order, it is possible to contribute to the improvement of the production efficiency of the substrate.

It is a top view which simplifies the whole structure of a component mounting machine and shows schematically. It is a side view which shows the configuration example of the use state in which the automatic feeder device and the reel holding device are mounted on a common pallet. It is a figure which showed the arithmetic processing flow of part type allocation of an embodiment. It is a figure explaining the arithmetic processing content of the arithmetic processing flow as an example.

(1. Overall configuration of component mounting machine 1)
First, the overall configuration of the component mounting machine 1 that performs the component type allocation method according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a plan view schematically showing the overall configuration of the component mounting machine 1 in a simplified manner. The direction from the right side to the left side of the paper surface in FIG. 1 is the X-axis direction in which the substrate K is carried in and out, and the direction from the rear on the lower side of the paper surface to the front on the upper side of the paper surface is the Y-axis direction. The component mounting machine 1 is configured by assembling a board transfer device 12, a detachable manual feeder device 7, an automatic feeder device 9, a component transfer device 14, a component camera 15, a control device 16, and the like on the machine base 19. There is. The board transfer device 12, the feeder devices 7 and 9, the component transfer device 14, and the component camera 15 are controlled by the control device 16, and each of them performs a predetermined operation.

The board transfer device 12 carries in the board K to the mounting implementation position, positions it, and carries it out. The substrate transfer device 12 is composed of a pair of first and second guide rails 121 and 122, a pair of conveyor belts, a clamp device, and the like. The first and second guide rails 121 and 122 extend in the transport direction (X-axis direction) across the center of the upper surface of the machine base 19, and are assembled to the machine base 19 in parallel with each other. A pair of endless annular conveyor belts (not shown) are arranged side by side on the inside of the first and second guide rails 121 and 122 facing each other. The pair of conveyor belts are rotated around with both edges of the substrate K placed on the conveyor transport surface, and the substrate K is carried in and out to the mounting implementation position set in the central portion of the machine base 19. A clamp device (not shown) is provided below the conveyor belt at the mounting position. The clamping device pushes up the substrate K, clamps it in a horizontal posture, and positions it at the mounting implementation position. As a result, the component transfer device 14 can perform the mounting operation at the mounting implementation position.

The manual feeder device 7 and the automatic feeder device 9 each sequentially supply parts. The feeder devices 7 and 9 have a flat shape having a small width direction dimension, and are arranged in rows in the first to ninth slots SL1 to SL9 of the common pallet 5 mounted on the machine base 19 (details will be described later). In FIG. 1, automatic feeder devices 9 are arranged in the fourth and fifth slots SL4 and SL5, and manual feeder devices 7 are arranged in the other slots SL1 to SL3 and SL6 to SL9. Behind the automatic feeder device 9, a reel holding device 6 that can be attached to and detached from the common pallet 5 is arranged. On the other hand, the manual feeder device 7 is integrally provided with a reel holding device. In an actual component mounting machine, a larger number of feeder devices 7 and 9 are often arranged in a row.

The component transfer device 14 sucks and collects components from the supply positions 94 of the plurality of feeder devices 7 and 9, and transports the components to the positioned substrate K for mounting. The component transfer device 14 is an XY robot type device that can move horizontally in the X-axis direction and the Y-axis direction. The component transfer device 14 includes a pair of Y-axis rails 141 and 142, a Y-axis slider 143, a mounting head 144, a nozzle tool 145, a board camera 146, and the like. The pair of Y-axis rails 141 and 142 are arranged near both side surfaces of the machine base 19 and extend in the front-rear direction (Y-axis direction). A Y-axis slider 143 is mounted on the Y-axis rails 141 and 142 so as to be movable in the Y-axis direction. The Y-axis slider 143 is driven in the Y-axis direction by a Y-axis ball screw mechanism (not shown).

The mounting head 144 is mounted on the Y-axis slider 143 so as to be movable in the X-axis direction. The mounting head 144 is driven in the X-axis direction by an X-axis ball screw mechanism (not shown). The nozzle tool 145 is interchangeably held by the mounting head 144. The nozzle tool 145 has one or a plurality of suction nozzles for sucking parts and mounting them on the substrate K. The board camera 146 is provided on the mounting head 144 alongside the nozzle tool 145. The substrate camera 146 captures an image of the fiducial mark attached to the substrate K to detect the exact position of the substrate K.

The component camera 15 is provided upward at the center position in the width direction of the upper surface of the machine base 19 between the substrate transfer device 12 and the feeder devices 7 and 9. The component camera 15 captures the state of the component sucked by the suction nozzle while the mounting head 144 is moving from the feeder devices 7 and 9 onto the substrate K. When the image pickup data of the component camera 15 reveals an error in the suction posture of the component, a deviation in the rotation angle, or the like, the control device 16 fine-tunes the component mounting operation as necessary, and if mounting is difficult, the component concerned Control to discard.

The control device 16 holds mounting sequence data that specifies the component type, mounting position, mounting order, compatible nozzle, and the like of the parts to be mounted on the substrate K. The control device 16 controls the component mounting operation according to the mounting sequence data based on the imaging data of the board camera 146 and the component camera 15, the detection data of the sensor shown in the figure, and the like. Further, the control device 16 sequentially collects and updates operation status data such as the number of production of the board K for which production has been completed, the mounting time required for mounting the component, and the number of occurrences of the component adsorption error.

(2. Configuration example of automatic feeder device 9, reel holding device 6, and manual feeder device 7)
Next, a configuration example of the automatic feeder device 9 and the reel holding device 6 will be described. FIG. 2 is a side view showing a configuration example of a used state in which the automatic feeder device 9 and the reel holding device 6 are mounted on the common pallet 5.

The common pallet 5 is detachably mounted on the upper side of the machine base 19. Not limited to this, the common pallet 5 may be fixedly mounted on the upper side of the machine base 19. The common pallet 5 has a feeder mounting portion 51 and a reel mounting portion 55. The feeder mounting portion 51 is formed by providing an upright portion 53 on the front side of a substantially rectangular flat surface portion 52, and has a substantially L shape in a side view. On the flat surface portion 52, nine first to ninth slots SL1 to SL9 extending in the front-rear direction are engraved side by side in the width direction. FIG. 1 shows the positions of the first, fifth, and ninth slots SL1, SL5, and SL9 in the width direction. The automatic feeder device 9 is inserted and mounted from the rear of the slots SL1 to SL9 toward the front upright portion 53. The first to ninth slots SL1 to SL9 correspond to the arrangement positions where the feeder devices 7 and 9 are arranged.

The automatic feeder device 9 has a tape insertion port 91 near the middle height of the rear end, and has an insertion lever 92 near the upper part of the rear end. By lifting the insertion lever 92, the first and second component storage tapes 85 and 86 can be inserted into the tape insertion port 91 in order. A feeding rail 93 is arranged from the tape insertion port 91 of the automatic feeder device 9 toward the upper part of the front end. The supply position 94 is set on the upper surface near the front end of the feed rail 93. A standby position 96 is set on the upper surface of the feeding rail 93 near the rear side near the tape insertion port 91. The inserted first and second component storage tapes 85 and 86 advance to the standby position 96 and temporarily stop.

A tape control unit 95 is provided above the standby position 96. The tape control unit 95 allows the first component storage tape 85 to be fed out from the standby position 96, and makes the second component storage tape 86 stand by. Moreover, when the first component storage tape 85 is exhausted, the tape control unit 95 automatically allows the second component storage tape 86 to be fed out from the standby position 96. Therefore, the splicing work for connecting the first and second component storage tapes 85 and 86 is unnecessary. A specific configuration of the tape control unit 95 is disclosed in, for example, Japanese Patent Application Laid-Open No. 2014-82454.

Further, the automatic feeder device 9 includes a tape feeding mechanism (not shown) composed of a servomotor, a sprocket, and the like. When the first component storage tape 85 is inserted up to the standby position 96, the automatic feeder device 9 drives the servomotor in the forward rotation. As a result, the automatic feeder device 9 automatically feeds out and loads the first component storage tape 85, and the substrate K is ready for production. That is, the automatic feeder device 9 has an automatic loading function. The second component storage tape 86 may be inserted immediately after the first component storage tape 85 is inserted, or may be in the middle of production by the first component storage tape 85.

Further, the automatic feeder device 9 reversely drives the servomotor when receiving the discharge command. As a result, the automatic feeder device 9 discharges the cut ends of the loaded first or second component storage tapes 85 and 86 from the supply position 94 toward the tape insertion port 91. That is, the automatic feeder device 9 has an automatic discharge function. The discharge command is commanded from the control device 16 or is commanded by the operator pressing the discharge button (not shown) attached to the automatic feeder device 9. The automatic feeder device 9 is provided with the tape control unit 95 and has an automatic loading function, which greatly reduces the labor of replenishing the new component storage tape. The applicant of the present application has filed a detailed configuration example of the automatic feeder device 9 in international application JP2014 / 064443, international application JP2014 / 083319, and the like.

The reel mounting portion 55 of the common pallet 5 is composed of two arm members 56, a front transfer plate 57, a rear transfer plate 58, and the like. The reel mounting portion 55 can mount one or a plurality of reel holding devices 6. As described in detail below, the two arm members 56 are fixed to the rear portions on both sides of the feeder mounting portion 51 in the width direction, respectively. The arm member 56 is formed so as to initially extend horizontally rearward, then incline and extend rearward and downward, and finally extend horizontally rearward. A front transfer plate 57 is passed so as to connect the inclined portions of the two arm members 56. A post-delivery plate 58 is passed so as to connect the horizontal portions behind the two arm members 56. The reel holding device 6 is detachably mounted on the upper side of the front transfer plate 57 and the rear transfer plate 58.

The reel holding device 6 rotatably holds the first and second component supply reels 81 and 82 in the front-rear direction while arranging them. The size of the reel holding device 6 in the width direction (direction of the reel axis) is not limited, and one or a plurality of first and second component supply reels 81 and 82 are held side by side in the width direction. Therefore, the reel holding device 6 corresponds to one or a plurality of automatic feeder devices 9 and is mounted behind the reel holding device 6.

When the parts stored in the second part storage tape 86 loaded in the automatic feeder device 9 are exhausted, the operator replaces the reel holding device 6 arranged behind the automatic feeder device 9 or replaces the reel holding device 6. Only the first and second component supply reels 81 and 82 are replaced. Subsequently, the operator pulls out the first and second component storage tapes 85 and 86 from the first and second component supply reels 81 and 82, and inserts them from the tape insertion port 91 of the automatic feeder device 9 to the standby position 96. This insertion work is lighter than the splicing work for connecting the two component storage tapes 85 and 86. As a result, the automatic loading function of the automatic feeder device 9 works, and the first and second component storage tapes 85 and 86 are sequentially fed to the supply positions 94.

On the other hand, the manual feeder device 7 is integrally provided with a reel holding device and directly holds the component supply reel. When the parts stored in the parts storage tape loaded in the manual feeder device 7 are exhausted, the operator needs to replenish a new parts supply reel and perform a splicing operation for connecting the two parts storage tapes. is there. The splicing work is a troublesome work for the worker. Since the manual feeder device 7 can be configured based on various known techniques, detailed description thereof will be omitted.

(3. Part type allocation method of the embodiment)
Next, the component type allocation method of the embodiment will be described with reference to FIGS. 3 and 4. The component type allocation method of the embodiment is realized by the arithmetic processing function of the control device (host computer) shown in the drawing that manages the substrate production line including the component mounting machine 1. The component type allocation method is not limited to this, and may be realized by the control device 16 of the component mounting machine 1 or a separately installed computer device that shares various data such as mounting sequence data. FIG. 3 is a diagram showing a calculation processing flow of the component type allocation method of the embodiment. Further, FIG. 4 is a diagram illustrating and explaining the arithmetic processing contents of the arithmetic processing flow.

As a precondition, a simple example in which parts of four types of parts PA, PB, PC, and PD are mounted on the substrate K to be produced is assumed. Of these, the parts of the three types of parts PA, PB, and PC can be supplied from either the automatic feeder device 9 or the manual feeder device 7. The parts of the part type PD correspond to the excluded part types described later, and can be supplied only from the manual feeder device 7. Further, it is assumed that two automatic feeder devices 9 are prepared and a manual feeder device 7 is also prepared. In reality, more types of parts are mounted on the substrate K, and there are many cases where the number of automatic feeder devices 9 is three or more.

In step S1 of FIG. 3, the control device sets the allocation mode based on the input setting operation of the operator or the like. As the allocation mode, either the workability evaluation mode M1 or the mounting point priority mode M2 is selectively set. The workability evaluation mode M1 is a mode for allocating parts types based on the amount of labor required for splicing work. On the other hand, the mounting point priority mode M2 is a mode in which component types are allocated based on the mounting points N of the components mounted per one substrate K.

In step S2, the control device confirms the presence or absence of the excluded component type. The excluded part type is a part type that cannot be supplied from the automatic feeder device 9 due to a special shape or the like, or is preferably supplied from the manual feeder device 7. The control device excludes the component type D, which is the exclusion component type, from the target of the arithmetic processing during the workability evaluation steps S4 to S6 and from step S14 to step S16, which will be described later.

In step S3, the control device controls the branching of the arithmetic processing flow based on the set mode. That is, the control device advances the execution of the arithmetic processing flow to the workability evaluation step S4 if the workability evaluation mode M1 is set, and executes the arithmetic processing flow in step S14 if the mounting point priority mode M2 is set. Proceed to.

In the workability evaluation step S4, the control device evaluates the amount of time and effort required for the splicing work. More specifically, the control device replenishes and connects new parts storage tape when the parts stored in the parts storage tape loaded in the manual feeder device 7 are exhausted. Evaluate each part type. In the present embodiment, the execution frequency S of the splicing work is used as an index indicating the magnitude of the labor of the splicing work. This is because if the implementation frequency S is large, the number of splicing operations increases and it takes time and effort.

The control device creates workability evaluation data in order to evaluate the execution frequency S of the splicing work. As shown in FIG. 4, the workability evaluation data is created based on the mounting sequence data and the component data. The mounting sequence data is data summarizing the component type, mounting position, mounting order, and the like of the parts to be mounted on the substrate K. The mounting sequence data indicates the number of mounting points N of each component type PA, PB, and PC mounted per board K. The number of mounting points NA of the component type PA is 100, the number of mounting points of the component type PB is NB = 50, and the number of mounting points of the component type PC is NC = 100.

On the other hand, the component data is data that summarizes information about each component used in the component mounting machine 1. The part data includes the reel names of each part type PA, PB, and PC, the number of storage points Q meaning the total number of parts stored in the parts storage tape, and the shape information of the parts. The number of storage points for the part type PA is QA = 10000, the number of storage points for the part type PB is QB = 3000, and the number of storage points for the part type PC is QC = 20000.

The control device calculates the execution frequency S of the splicing work by dividing the number of mounting points N by the number of stored points Q for each part type PA, PB, and PC. The unit of the implementation frequency S is (times / sheet). It is calculated as the implementation frequency SA = (NA / QA) = (100/10000) = (1/100) related to the part type PA. This means that the splicing work related to the component type PA is performed once for every 100 substrates produced. Similarly, the implementation frequency SB related to the part type PB is calculated as SB = (50/3000) = (1/60), and the implementation frequency SC related to the part type PC is calculated as (100/20000) = (1/200). To.

Further, the control device ranks the priority Y in descending order of the implementation frequency S. That is, the priority YB of the part type PB having the highest implementation frequency SB is set to 1st, and the priority YA of the part type PA having the intermediate implementation frequency SA is set to 2nd, and the part having the lowest implementation frequency SC. The priority of the product type PC is YC = 3rd. As a result, the workability evaluation data shown in FIG. 4 is completed.

In the next step S5, the control device preferentially allocates to the automatic feeder device 9 in order from the component type having the highest priority Y. In the first step S5, the control device allocates the component type PB having the priority YB = 1 to the first automatic feeder device 9. In the next step S6, the control device returns the execution of the arithmetic processing flow to step S5 if there is a remaining number of the automatic feeder devices 9 to which the part types are not assigned, and executes the arithmetic processing flow if there is no remaining number. Proceed to step S7. In the first step S6, since the component type is not assigned to the second automatic feeder device 9, the control device returns the execution of the arithmetic processing flow to step S5.

In the second step S5, the control device allocates the component type PA having the priority YA = 2 to the second automatic feeder device 9. In the second step S6, since the remaining number of the automatic feeder devices 9 is exhausted, the control device advances the execution of the arithmetic processing flow to step S7. The loop calculation process including step S5 and step S6 corresponds to the automatic side allocation step of the present invention.

In step S7 after exiting the loop calculation process, the control device allocates the part type PC having the priority YC = 3 which has not been assigned yet and the part type D which is the excluded part type to the manual feeder device 7.

Further, in step S14, which proceeds when the mounting point priority mode M2 is set in step S3, the control device ranks the priority Z in descending order of the mounting point number N. That is, the number of mounting points NA = the number of mounting points NC = 100, and the priority ZA of the component type PA = 1st in the same ratio, and the priority ZC of the component type PC = the 1st in the same ratio. Further, the number of mounting points is as small as NB = 50, and the priority ZB of the component type PB is 3rd.

In the next step S15 and step S16, similarly to the workability evaluation mode M1, the control device preferentially allocates to the automatic feeder device 9 in order from the component type having the highest priority Z. Specifically, the control device allocates the component type PA and the component type PC having the priority ZA = priority ZC = 1st place in the same ratio to the two automatic feeder devices 9. As a result, the remaining number of the automatic feeder devices 9 is eliminated, so that the control device advances the execution of the arithmetic processing flow to step S7. In step S7, the control device allocates the part type PB having the priority ZB = 3rd place, which has not been assigned yet, and the part type D, which is the excluded part type, to the manual feeder device 7.

As described above, the allocation result may differ depending on the allocation mode setting. If the mounting point priority mode M2 is set, the component type PB having the maximum splicing work execution frequency SB is assigned to the manual feeder device 7. As a result, the number of splicing operations increases, and the production downtime due to the operations increases. On the other hand, when the workability evaluation mode M1 is set, the component type PC having the minimum splicing work execution frequency SC is allocated to the manual feeder device 7, and the number of splicing work is reduced. Therefore, the workability evaluation mode M1 is usually superior to the mounting point priority mode M2.

In a subsequent step S8, the control device performs the allocation adjustment process. In the allocation adjustment process, the mounting order of each part type A to D and the order in which the manual feeder device 7 and the automatic feeder device 9 are arranged in the first to ninth slots SL1 to SL9 are adjusted, and the mounting sequence data is updated. Will be done. As a general trend, the automatic feeder device 9, which is advantageous in reducing splicing work, is often applied to parts that are consumed quickly. For this reason, the automatic feeder device 9 is often arranged near the center in the width direction close to the component camera 15 and the substrate K, but it is not unconditionally determined. Since various techniques have been publicly known regarding the allocation adjustment process, detailed description thereof will be omitted.

(4. Embodiments and effects)
The component type allocation method of the embodiment is an automatic feeder having an automatic loading function that automatically loads the component storage tapes 85 and 86 when the component storage tapes 85 and 86 containing the components are inserted into the plurality of component storage portions. This is a part type allocation method for allocating a plurality of part types PA to PD to the device 9 and the manual feeder device 7 having no automatic loading function, and the parts stored in the parts storage tape loaded in the manual feeder device 7 are Workability evaluation step S4, which evaluates the amount of time and effort required for splicing work to replenish and connect new parts storage tape for each part type PA, PB, and PC when it runs out, and part types that require a large amount of time and effort for splicing work. It has an automatic side allocation step (steps S5 and S6) for preferentially allocating PB and PA to the automatic feeder device 9.

According to this, the magnitude of the time and effort of the splicing work in the manual feeder device 9 is evaluated, and the parts type in which the time and effort of the splicing work is large are preferentially allocated to the automatic feeder device 9. Therefore, the automatic feeder device 9 can be preferentially used over the manual feeder device 7, and the automatic feeder device 9 can be effectively utilized to reduce the splicing work. Further, since the labor of the splicing work in the manual feeder device 7 is reduced in descending order, it is possible to contribute to the improvement of the production efficiency of the substrate K.

Further, in the workability evaluation step S4, at least one item of the execution frequency S of the splicing work in the manual feeder device 7, the difficulty level of the splicing work depending on the difference in the properties of the component storage tapes 85 and 86, and the required time of the splicing work. Based on this, it is possible to evaluate the amount of time and effort required for splicing work.

In addition to the implementation frequency S, the difficulty level and the required time can be adopted as an index indicating the amount of time and effort required for the splicing work. For example, the difficulty level of the splicing work depends on the difference in the material and hardness of the parts storage tapes 85 and 86. In addition, the difference between the embossed tape in which the component storage portion is formed in a convex shape and the flat tape having a flat surface also has an effect. Therefore, by preferentially allocating the parts types having a high degree of difficulty in the splicing work to the automatic feeder device 9, the work reduction effect becomes remarkable.

Further, it is possible to combine two or more indexes indicating the magnitude of the time and effort of the splicing work. For example, when the required time of the splicing work changes depending on the properties of the component storage tape, it is preferable to use the product of the implementation frequency S and the required time. By preferentially allocating the parts with a large product type to the automatic feeder device 9, the production stop time can be shortened.

Further, in the workability evaluation step S4, the number of mounting points N of each component mounted per board K is divided by the number of storage points Q of each component stored in the component storage tapes 85 and 86 to perform the splicing work. The implementation frequency S is calculated respectively, and it is evaluated that the larger the implementation frequency S, the greater the labor of the splicing work. According to this, the implementation frequency S can be easily calculated by using the mounting sequence data and the component data created in advance for the production of the substrate K, and the labor of the splicing work can be easily evaluated.

The part type allocating method of the embodiment can also be implemented as a part type allocating device. This component type allocation device may be realized by the arithmetic processing function of the control device (host computer) shown in the figure that manages the board production line including the component mounting machine 1, and is not limited to this. It may be realized by the control device 16 of the mounting machine 1 or a separately installed computer device that shares various data such as mounting sequence data. That is, the parts allocating device of the embodiment has an automatic loading function of automatically loading the parts storage tapes 85 and 86 when the parts storage tapes 85 and 86 containing the parts are inserted into the plurality of parts storage portions. A component type allocation device that allocates a plurality of component types PA to PD to the feeder device 9 and the manual feeder device 7 that does not have an automatic loading function, and is a component stored in the component storage tape loaded in the manual feeder device 7.
