  As described in the “Background Art” section, a container such as a tray for storing a plurality of equipment is used to supply electronic parts and the like. For example, a plurality of trays are stacked, and components are sequentially taken out from the uppermost tray of the plurality of stacked trays. The lifter raises the plurality of trays until the uppermost tray reaches the height position for supplying the components when supplying the components, and descends to the replenishing position when the trays are replenished. When a tray is refilled, it takes time for the lifter to descend to the refill position, time for the tray to be refilled, and time for the lifter to return to its original position after refilling, and the parts supply may stop at these times There is. Therefore, the supply efficiency of components is lowered. Therefore, the present inventors have devised a technique for improving the supply efficiency of parts as follows.

  For example, the component supply method according to one aspect of the present disclosure is a component supply method for supplying components accommodated in a container, and (a) a step of placing a plurality of stacked containers on a stage. And (b) the stage between a take-out position where the uppermost container among the plurality of stacked containers is taken out and a replenishment position where the container is replenished to the stage. (C) a step of taking out the uppermost container from the stage and moving it to a supply position; (d) obtaining a quantity of the parts of the container; and (e) the stage. Obtaining the quantity of the container above, (f) waiting the stage at the take-out position, and (g) waiting the stage at the replenishment position, the step (c) After the top of the next top During the next step (c) for taking out the container, when the quantity of the parts acquired in the step (d) is less than a first predetermined quantity, the step (f) is performed, and the step ( When the quantity of the parts acquired in d) is not less than the first predetermined quantity and the quantity of the containers acquired in the step (e) is smaller than a second predetermined quantity, the step (g )I do.

  According to the said aspect, when there are few quantities in the container, the taking-out space | interval of the container from a stage becomes short. In such a case, during the operation of taking out the container from the next container take-out operation, the stage is made to stand by at the take-out position, and the take-out efficiency of the container is prioritized. Moreover, when there are many parts in a container, the taking-out space | interval of the container from a stage becomes long. Furthermore, if the quantity of containers on the stage is less than the second predetermined quantity, the containers can be replenished. In such a case, the replenishment time of the container can be shortened by waiting the stage at the refill position between the container take-out operation and the next container take-out operation. Furthermore, since the container take-out interval is long, the influence of the movement of the stage to the refill position on the container take-out can be suppressed. Therefore, the supply efficiency of parts can be improved.

  In the component supply method according to one aspect of the present disclosure, in the step (e), the quantity of the containers may be acquired from the height position of the stage.

  According to the said aspect, the position determination of the stage to the taking-out position according to the quantity of containers and the replenishment position becomes easy.

  In the component supply method according to an aspect of the present disclosure, in the step (d), the quantity of the component set in the container may be acquired as the number of the component of the container.

  According to the said aspect, it is not necessary to detect the quantity of the components in the said container for every container. That is, since a device for detecting the quantity of parts in the container is not required, the device can be simplified and the cost can be reduced.

  In the component supply method according to an aspect of the present disclosure, between the step (c) and the next step (c) after the step (c), the quantity of the parts acquired in the step (d) is the first predetermined quantity. If it is the above and the quantity of the containers acquired in the step (e) is equal to or larger than a second predetermined quantity, the step (f) may be performed.

  According to the said aspect, since the quantity of the container of a stage is large, the replenishment of a container is not required. In such a case, the take-out efficiency of the container is improved by making the stage stand by at the take-out position during the take-out operation of the next container. Therefore, the supply efficiency of parts can be improved.

Examples of the memory may be a volatile memory such as a RAM (Random Access Memory) and a non-volatile memory such as a ROM (Read-Only Memory). A part or all of the functions of the control unit 53 may be achieved by the CPU executing a program recorded in the ROM using the RAM as a working memory.

  The storage unit 61 makes it possible to store various information and to retrieve the stored information. The storage unit 61 is realized by a storage device such as a semiconductor memory such as a ROM, a RAM, or a flash memory, a hard disk drive, or an SSD (Solid State Drive). In the present embodiment, the storage unit 61 is included in the control unit 53, but may be provided separately from the control unit 53.

  The acquisition unit 54 acquires the quantity of the parts 3 accommodated in the tray 5. For example, for various trays, information indicating the types and quantities of components that can be accommodated in the trays is stored in the storage unit 61 in advance. That is, the storage unit 61 stores the quantity that accommodates the parts set in the tray. The acquisition unit 54 may acquire the quantity of components 3 that can be accommodated in the tray 5 on the placement stage 13 as the quantity of components 3 accommodated in the tray 5 by referring to the storage unit 61. Here, the acquisition unit 54 is an example of a first acquisition unit.

  The 1st monitoring part 55 monitors the remaining number which is the quantity of the components 3 accommodated in the tray 5 transferred to 2nd transfer position B2. Specifically, the first monitoring unit 55 counts the number of components 3 taken out from the tray 5 using information on the operation of the mounting head 51 sent from the component mounting apparatus 4. Further, the first monitoring unit 55 calculates the remaining number of components 3 in the tray 5 by subtracting the count number from the number of components 3 that can be accommodated in the tray 5 stored in the storage unit 61.

  The transfer control unit 56 moves the table 22 or 26 from the first transfer position B1 to the second transfer position B2 based on the remaining number of parts 3 acquired from the first monitoring unit 55, and the second transfer position B2. The table 26 or 22 is moved from to the first transfer position B1. When the table 26 moves, the transfer control unit 56 also moves the table 26 up and down.

  The transfer control unit 57 performs the operation of the transfer arm 41 based on the remaining number of parts 3 acquired from the first monitoring unit 55 and the information on the positions of the tables 22 and 26 acquired from the transfer control unit 56. Control. The transfer control unit 57 controls the transfer arm 41 so that the pallet 12 holding the used tray 5A that has been emptied by taking out the components 3 is transferred to the first transfer position B1 by the table 22 or 26, and is transferred to the collection stage 33 at the transfer position D1. Further, the transfer control unit 57 controls the transfer arm 41 to take out the pallet 12 holding the uppermost tray 5 from the mounting stage 13 at the take-out position A1, and the first where the tray 5 is not mounted. Transfer to the table 22 or 26 at the transfer position B1.

  The second monitoring unit 58 monitors the ascending / descending state of the mounting stage 13 of the supply side lifter 20 and the recovery stage 33 of the recovery side lifter 40. The second monitoring unit 58 performs the above monitoring based on the detection results acquired from the light receiving units U1 and U3 and the detection sensors S1 to S5. Based on the monitoring result of the second monitoring unit 58, the control unit 53 detects the number of trays 5 placed on the placement stage 13 and the number of used trays 5 </ b> A placed on the collection stage 33. . That is, the control unit 53 detects or acquires the height position in the Z direction of the mounting stage 13 and the collection stage 33 based on the monitoring result of the second monitoring unit 58, and the light receiving units U1 and U3 are in the ON state. Based on the height positions of the loading stage 13 and the collection stage 33 at this time, the number of trays on each stage is calculated, that is, acquired. The light receiving units U1 and U3 are in the “ON” state when detecting the tray 5 or the used tray 5A, and are in the “OFF” state when not detecting them. The detection sensors S1 to S5 are in the “ON” state when detecting the main body portion 18b or 38b of the plate-like member 18 or 38, and are in the “OFF” state when not detecting.

  The monitoring of the supply side lifter 20 by the second monitoring unit 58 will be described with reference to FIGS. 3 and 6. FIG. 6 is a schematic side view showing a state of the supply-side lifter 20 according to the embodiment. When the first detection sensor S1 and the second detection sensor S2 are ON and the first light receiving unit U1 is OFF, the second monitoring unit 58 is in the “first state” where the mounting stage 13 is located at the replenishment position A2. It is judged that.

  When at least the second detection sensor S <b> 2 is OFF, the second monitoring unit 58 is “the second state” in which the placement stage 13 is higher than the first state but the number of placed pallets 12 is large. It is judged that. At this time, the number of pallets 12 is equal to or greater than the second predetermined amount.

  When the first detection sensor S1 is OFF and the second detection sensor S2 is ON, the second monitoring unit 58 moves up to the vicinity of the take-out position A1 and the quantity of the pallets 12 placed. It is determined that the “third state” is small. At this time, the quantity of the pallet 12 is smaller than the second predetermined quantity.

  When the first detection sensor S1, the second detection sensor S2, and the first light receiving unit U1 are ON, the second monitoring unit 58 raises the mounting stage 13 to the take-out position A1, and the pallet 12 on the mounting stage 13 Is the “fourth state”, which is empty.

  Furthermore, monitoring of the collection side lifter 40 by the second monitoring unit 58 will be described. The second monitoring unit 58 determines that the state is the “fifth state” at least when the third detection sensor S3 is OFF. In the fifth state, the collection stage 33 is raised to a predetermined position away from the collection position D2, and the number of pallets 12 placed on the upper surface thereof is zero or small, that is, the pallet 12 is collected. It is in a state where there is a sufficient margin until.

  The second monitoring unit 58 determines that the state is the “sixth state” when only the third detection sensor S3 is ON. In the sixth state, the collection stage 33 is lowered from the fifth state, and the quantity of the pallets 12 placed on the upper surface thereof is equal to or greater than the third predetermined quantity, that is, until the pallet 12 is collected. There is little room.

  The second monitoring unit 58 determines that the state is the “seventh state” when the third detection sensor S3 and the fourth detection sensor S4 are ON. In the seventh state, the collection stage 33 is lowered from the sixth state, and the pallets 12 stacked on the upper surface thereof are full.

  When the third to fifth detection sensors S3 to S5 are ON, the second monitoring unit 58 determines that the recovery stage 33 is in the “eighth state” that is lowered to the recovery position D2.

  Note that by increasing the number of detection sensors, the second monitoring unit 58 can further subdivide and monitor the ascending / descending state of the mounting stage 13 and the collection stage 33 and the number of trays 5 stacked on these. . By reducing the number of detection sensors, the second monitoring unit 58 can reduce the state of monitoring of the up / down state and the number of trays 5.

  Returning to FIG. 5, the first lifter control unit 59 controls the operation of the supply-side lifter 20. The first lifter control unit 59 receives the inspection light received by the first light receiving unit U1, the monitoring result of the second monitoring unit 58, and the number of components 3 that can be stored in the tray 5 stored in the storage unit 61. Based on the above, the elevation of the mounting stage 13 is controlled.

  Specifically, the first lifter control unit 59 operates as follows when the quantity of the parts 3 that can be accommodated in the tray 5 is smaller than the first predetermined quantity. When the mounting stage 13 is in the second state or the third state, the first lifter control unit 59 raises the mounting stage 13 until the uppermost tray 5 blocks the inspection light incident on the first light receiving unit U1. . Further, each time the uppermost pallet 12 is taken out by the transfer arm 41, the first lifter control unit 59 raises the mounting stage 13 by one pallet and again blocks the inspection light incident on the first light receiving unit U1. In this manner, the uppermost tray 5 is supplied to the take-out position A1. Thus, each time the pallet 12 is taken out from the placement stage 13, the placement stage 13 is raised, and the quantity of the pallets 12 on it is reduced. Then, the first lifter control unit 59, in the period from the removal of the first uppermost tray 5 to the removal of the next second uppermost tray 5, specifically, over the entire period. With the second uppermost tray 5 being positioned at the take-out position A1, the mounting stage 13 is put on standby.

  The first lifter control unit 59 replenishes the placement stage 13 when the placement stage 13 is in the fourth state and when the user inputs replenishment of the pallet 12 via an input device (not shown). Lower to position A2. That is, the first lifter control unit 59 places the mounting stage 13 in the first state and stands by. After refilling the pallet 12, the first lifter control unit 59 operates in the same manner as in the second state. The first lifter control unit 59 may lower the placement stage 13 to the replenishment position A2 when the quantity of the pallets 12 on the placement stage 13 becomes less than a preset quantity.

  Further, the first lifter control unit 59 operates as follows when the quantity of the parts 3 that can be accommodated in the tray 5 is equal to or larger than the first predetermined quantity. When the mounting stage 13 is in the second state, the first lifter control unit 59 raises the mounting stage 13 until the uppermost tray 5 blocks the inspection light incident on the first light receiving unit U1. Further, each time the uppermost pallet 12 is taken out, the first lifter control unit 59 raises the mounting stage 13 by one pallet and again blocks the inspection light incident on the first light receiving unit U1. The tray 5 is supplied to the take-out position A1. In the second state, the number of pallets 12 on the mounting stage 13 is equal to or greater than the second predetermined amount. Then, the first lifter control unit 59 continuously continues over the entire period from the removal of the first uppermost tray 5 to the removal of the next second uppermost tray 5. Then, the mounting stage 13 is put on standby in a state where the second uppermost tray 5 is positioned at the extraction position A1.

  When the placement stage 13 is in the third state, the first lifter control unit 59 lowers the placement stage 13 to the replenishment position A2 after the uppermost tray 5 is taken out, that is, the placement stage 13. To the first state. In the third state, the number of pallets 12 on the placement stage 13 is smaller than the second predetermined amount. Specifically, the first lifter control unit 59 performs a period from when the first uppermost tray 5 is taken out to when the next second uppermost tray 5 is taken out. Continuously throughout, the mounting stage 13 is lowered to the replenishment position A2 and waits. The first lifter control unit 59 then places the placement stage so that the second uppermost tray 5 is positioned at the takeout position A1 immediately before the transfer arm 41 takes out the second uppermost tray 5. 13 is raised. Thereby, the user can replenish the tray 5 to the mounting stage 13 in the replenishment position A2 while the component 3 is mounted on the substrate 2 from the tray 5 at the second transfer position B2. The first lifter control unit 59 sets the timing of raising the mounting stage 13 to the information on the remaining number of parts 3 in the tray 5 at the second transfer position B2 obtained from the first monitoring unit 55, the transfer control unit. It may be determined from the movement status of the table 22 or 26 acquired from 56, the transfer status of the pallet 12 acquired from the transfer control unit 57, or the like.

  In this way, the first lifter control unit 59 takes out the extraction position A1 every time the uppermost tray 5 is taken out from the placement stage 13 during a period when the quantity of the pallets 12 on the placement stage 13 is smaller than the second predetermined quantity. And the loading stage 13 are moved up and down between the replenishment position A2. And the 1st lifter control part 59 will control the mounting stage 13 in a 2nd state, if the quantity of the pallet 12 on the mounting stage 13 becomes more than a 2nd predetermined quantity. Further, the fourth state of the mounting stage 13 does not exist in this case.

  The second lifter control unit 60 controls the operation of the collection side lifter 40. The second lifter control unit 60 controls the raising and lowering of the collection stage 33 based on the light receiving state of the inspection light by the second light receiving unit U3 and the monitoring result of the second monitoring unit 58. Specifically, the second lifter control unit 60 determines that the pallet 12 is transferred onto the recovery stage 33 at the transfer position D1 when the recovery stage 33 is in the fourth state, the fifth state, or the sixth state. Each time the inspection light incident on the second light receiving unit U3 is blocked, the collection stage 33 is lowered by one pallet. That is, when the pallet 12 is transferred to the collection stage 33 by the transfer arm 41, the collection stage 33 or the uppermost pallet 12 already transferred to the collection stage 33 is lowered by one pallet from the transfer position D1. Done in In this way, each time the pallet 12 is transferred to the collection stage 33, the collection stage 33 is lowered and the number of pallets 12 on it is increased.

  Further, the second lifter control unit 60 moves the collection stage 33 to the collection position D2 when the collection stage 33 is in the seventh state and when an input indicating collection of the pallet 12 is made by the user via an input device (not shown). To the eighth state. Further, the second lifter control unit 60 causes the collection stage 33 to wait until the pallet 12 on the collection stage 33 is removed. When the pallet 12 on the collection stage 33 is removed, the second lifter control unit 60 raises the collection stage 33 to the transfer position D1.

  The notification unit 62 includes a display device provided in the component supply device 1. The notification unit 62 notifies that the pallet 12 on the mounting stage 13 is empty or needs to be refilled and that the pallet on the collection stage 33 is full by a warning sound and flashing light. The user is audibly and / or visually notified. An example of a state where the pallet 12 on the mounting stage 13 needs to be replenished is a state where the number of the pallets 12 on the mounting stage 13 is smaller than the second predetermined amount.

  Next, the operation of the component supply apparatus 1 according to the embodiment will be described. As shown in FIGS. 1 and 3 to 5, the control unit 53 of the component supply device 1 raises the mounting stage 13 until the stacked uppermost tray 5 is located at the take-out position A1. Next, the control unit 53 takes out the pallet 12 holding the uppermost tray 5 from the mounting stage 13 using the transfer arm 41. After the pallet 12 is taken out, the control unit 53 raises the placement stage 13 to supply the uppermost tray 5 to the take-out position A1 before the pallet 12 is next taken out using the transfer arm 41.

  Further, the control unit 53 transfers the pallet 12 held by the transfer arm 41 onto the table 22 or 26 located at the first transfer position B1. On the other hand, the table 26 or 22 is located at the second transfer position B <b> 2, and the mounting head 51 of the component mounting apparatus 4 mounts the component 3 of the tray 5 on the substrate 2. During the loading, the transfer is performed. After completing the mounting of all the components 3, the control unit 53 moves the tables 22 and 26 to exchange their positions. At this time, the control unit 53 lowers the table 26 and passes below the table 22. Thereby, the used tray 5A is arranged at the first transfer position B1, and the new tray 5 is arranged at the second transfer position B2. After the replacement, the component mounting apparatus 4 mounts the component 3 of the new tray 5 positioned at the second transfer position B2 on the substrate 2.

  Next, during mounting of the component 3 of the tray 5 at the second transfer position B2, the control unit 53 removes the pallet 12 holding the used tray 5A at the first transfer position B1 using the transfer arm 41, and transfers the pallet. Transfer to the collection stage 33 at the loading position D1. Thereafter, the control unit 53 takes out the pallet 12 holding the tray 5 supplied to the take-out position A1 using the transfer arm 41 and transfers it onto the table 22 or 26 at the first transfer position B1. Thereby, a new tray 5 is arranged at the first transfer position B1. When the pallet 12 is transferred onto the collection stage 33, the control unit 53 lowers the collection stage 33 by one pallet. In this manner, the control unit 53 supplies the tray 5 taken out from the tray supply unit 6 to the tray transfer unit 7 and transfers the used tray 5A from which the components 3 have been taken out by the tray transfer unit 7 to the tray collection unit 8. To do.

  Next, the operation of the supply-side lifter 20 will be described with reference to FIGS. 7A and 7B. The operation described below is executed based on a control program stored in advance in the control unit 53 of the component supply apparatus 1. 7A and 7B are flowcharts illustrating an example of the operation of the component supply device 1 according to the embodiment. First, in step S <b> 11, the control unit 53 acquires an accommodation quantity that is the quantity of the parts 3 accommodated in the tray 5. In the present embodiment, the control unit 53 acquires the storage quantity from the storage unit 61.

  Next, in step S12, the control unit 53 determines whether or not the accommodation quantity is less than the first predetermined quantity. The control unit 53 proceeds to step S13 when it is less than the first predetermined quantity (Yes in step S12), and proceeds to step S14 when it is greater than or equal to the first predetermined quantity (No in step S12).

  In step S13, the control unit 53 determines the light receiving state of the first light receiving unit U1. Specifically, the control unit 53 determines whether the first light receiving unit U1 is ON or OFF. When the first light receiving unit U1 is ON (Yes in step S13), the control unit 53 proceeds to step S16. When the first light receiving unit U1 is OFF (No in Step S13), the control unit 53 proceeds to Step S15.

  In step S15, the control unit 53 controls the supply side lifter 20, raises the mounting stage 13 until the first light receiving unit U1 is turned on, and proceeds to step S16. Thereby, the uppermost tray 5 of the mounting stage 13 is positioned at the take-out position A1. That is, the control unit 53 continuously waits for the placement stage 13 at the take-out position A <b> 1 after the uppermost tray 5 is taken out from the placement stage 13 until the next uppermost tray 5 is taken out. Let

  In step S <b> 16, the control unit 53 determines whether the quantity of the pallets 12 on the placement stage 13 is 0 based on the monitoring result of the second monitoring unit 58. For example, when the mounting stage 13 is in the fourth state, the number of pallets 12 is zero. When the quantity is 0 (Yes in Step S16), the control unit 53 proceeds to Step S17, and when the quantity is not 0 (No in Step S16), the control unit 53 returns to Step S13. Note that the criterion for determining the quantity of pallets 12 in step S16 may not be 0, and may be a preset quantity such as the remaining number of pallets 12 that need to be replenished with the pallet 12 to the mounting stage 13. Good.

  In step S <b> 17, the control unit 53 notifies the user of a request for replenishment of the tray 5 via the notification unit 62. Next, in step S18, the control unit 53 controls the supply side lifter 20 to lower the placement stage 13 to the replenishment position A2. Thereafter, the tray 5 is replenished by the user.

  Next, in step S19, after the replenishment of the tray 5 is completed, the control unit 53 controls the supply side lifter 20, raises the placement stage 13, and takes the uppermost tray 5 to the removal position A1. Then, the control part 53 repeats this process from step S11. Note that the control unit 53 may recognize completion of refilling of the tray 5 from input information by the user via an input device (not shown).

  In step S <b> 14, the control unit 53 determines whether the quantity of the pallets 12 on the placement stage 13 is equal to or larger than the second predetermined quantity based on the monitoring result of the second monitoring unit 58. The control unit 53 proceeds to step S20 when it is equal to or greater than the second predetermined quantity (Yes in step S14), and proceeds to step S21 when it is less than the second predetermined quantity (No in step S14).

  In step S20, the control unit 53 determines whether the first light receiving unit U1 is ON or OFF, as in step S13. When the first light receiving unit U1 is ON (Yes in step S20), the control unit 53 returns to step S14. When the first light receiving unit U1 is OFF (No in Step S20), the control unit 53 proceeds to Step S22.

  In step S22, the control unit 53 controls the supply-side lifter 20, raises the mounting stage 13 until the first light receiving unit U1 is turned on, and returns to step S14. That is, the control unit 53 continuously waits for the placement stage 13 at the take-out position A <b> 1 after the uppermost tray 5 is taken out from the placement stage 13 until the next uppermost tray 5 is taken out. Let

  Moreover, in step S21, the control part 53 judges ON or OFF of the 1st light-receiving part U1 similarly to step S13. When the first light receiving unit U1 is ON (Yes in step S21), the control unit 53 repeats step S21. When the first light receiving unit U1 is OFF (No in Step S21), the control unit 53 proceeds to Step S23.

  In step S23, the control unit 53 controls the supply side lifter 20 to lower the placement stage 13 to the replenishment position A2. That is, the control unit 53 continuously waits for the placement stage 13 at the replenishment position A2 during the period from when the uppermost tray 5 is removed from the placement stage 13 to when the next uppermost tray 5 is removed. Let

  Next, in step S <b> 24, the control unit 53 notifies the user of a request for replenishment of the tray 5 via the notification unit 62. Next, in step S25, the control unit 53 controls the supply-side lifter 20 at a predetermined timing to raise the placement stage 13 and bring the uppermost tray 5 to the removal position A1. An example of the predetermined timing is a timing immediately before the uppermost tray 5 is taken out by the transfer arm 41, and is a timing for raising the mounting stage 13 determined by the first lifter control unit 59.

  Next, in step S <b> 26, the control unit 53 determines whether or not the tray 5 is replenished to the mounting stage 13. Specifically, the control unit 53 determines whether or not the quantity of the pallets 12 on the placement stage 13 is greater than or equal to a second predetermined quantity. When the amount is equal to or larger than the second predetermined quantity (Yes in Step S26), the control unit 53 proceeds to Step S11 and repeats the process from Step S11. In this case, it can be considered that the tray 5 has been replenished to the mounting stage 13. The control part 53 returns to step S21, when it is less than the second predetermined quantity (No in step S26). In this case, it can be considered that the tray 5 has not been replenished to the mounting stage 13.

  As described above, the control unit 53 switches the control of the supply-side lifter 20 in accordance with the capacity of the tray 5. When the amount of the tray 5 that is less than the first predetermined amount is small, the control unit 53 performs a period from when the uppermost tray 5 is removed from the placement stage 13 to when the next uppermost tray 5 is removed. During the period, the mounting stage 13 is put on standby so that the uppermost tray 5 is located at the take-out position A1, and the take-out efficiency of the tray 5 from the tray supply unit 6 is prioritized. On the other hand, when there is a large amount of trays 5 that are equal to or greater than the first predetermined quantity, the control unit 53 removes the next uppermost tray 5 after the uppermost tray 5 is removed from the placement stage 13. During this period, the stage 13 that needs to be refilled with the tray 5 is put on standby at the refill position A2, and the time for refilling the tray 5 is shortened.

  As described above, the component supply device 1 according to the embodiment supplies the component 3 accommodated in the tray 5. The component supply device 1 includes a placement stage 13 on which a plurality of stacked trays 5 are placed, a take-out position A1 from which the uppermost tray 5 among the plurality of stacked trays 5 is taken out, A supply-side lifter 20 as an elevating device that raises and lowers the mounting stage 13 between the replenishment position A2 in which the tray 5 is replenished to the mounting stage 13 and the uppermost tray 5 from the mounting stage 13 are taken out. The transfer unit 9 as a moving device that moves to the position, the acquisition unit 54 as a first acquisition unit that acquires the quantity of the components 3 of the tray 5, and the second that acquires the quantity of the tray 5 on the mounting stage 13. And a control unit 53 as an acquisition unit. When the quantity of the parts 3 acquired by the acquisition unit 54 is smaller than the first predetermined quantity, the supply-side lifter 20 has the second uppermost tray 5 after the first uppermost tray 5 is taken out. In the period until removal, the mounting stage 13 is put on standby at the removal position A1. When the quantity of the parts 3 acquired by the acquisition unit 54 is greater than or equal to the first predetermined quantity and the quantity of the tray 5 acquired by the control unit 53 is less than the second predetermined quantity, the supply side lifter 20 In the period from the removal of the first uppermost tray 5 to the removal of the next second uppermost tray 5, the mounting stage 13 is put on standby at the replenishment position A2.

  Note that waiting the mounting stage 13 at the extraction position A1 may mean waiting the mounting stage 13 so that the uppermost tray 5 is positioned at the extraction position A1. The placement stage 13 stands by at the replenishment position A2. The placement stage 13 stands by at the replenishment position A2, and the placement stage 13 stands by near the replenishment position A2. Including. For example, the placement stage 13 being positioned in the vicinity of the replenishment position A2 means that the placement stage 13 is located at an intermediate position between the take-out position A1 and the replenishment position A2, and that the placement stage 13 is located from the take-out position A1. May also include being located near the replenishment position A2.

  According to the above configuration, when the number of the parts 3 in the tray 5 is small, the interval at which the tray 5 is removed from the mounting stage 13 is shortened. In such a case, during the operation of taking out the first uppermost tray 5 to the next operation of taking out the second uppermost tray 5, the loading stage 13 is made to wait at the removal position A1, and the tray 5 is taken out. Efficiency is a priority. Further, when the number of the parts 3 in the tray 5 is large, the interval at which the tray 5 is removed from the mounting stage 13 becomes long. Furthermore, when the quantity of the tray 5 of the mounting stage 13 is smaller than the second predetermined quantity, the tray 5 can be replenished. In such a case, the tray 5 is placed in the replenishment position A2 between the takeout operation of the first uppermost tray 5 and the next takeout operation of the second uppermost tray 5, whereby the tray 5 It is possible to shorten the replenishment time. For example, the user can replenish the tray 5 without waiting for the placement stage 13 to descend to the replenishment position A2. Alternatively, the user can replenish the tray 5 during the period. Further, since the take-out interval of the tray 5 is long, the influence of the movement of the mounting stage 13 to the replenishment position A2 on the take-out of the tray 5 can be suppressed. Therefore, the supply efficiency of the component 3 is improved.

  The first predetermined quantity and the second predetermined quantity may be arbitrarily set according to the capabilities of the component supply apparatus 1 and the component mounting apparatus 4, the configuration of the substrate 2, and the like. For example, the first predetermined quantity may be set according to the component mounting capability of the component mounting device 4 on the substrate 2 and the arrangement of components on the substrate 2. The second predetermined quantity is the number of trays 5 that can be placed on the placement stage 13 in the component supply apparatus 1, the raising / lowering speed of the supply-side lifter 20, the moving speed of the transfer arm 41, the transfer speed of the tray transfer unit 7, etc. It may be set according to
