In the parts supply management system equipped with the parts storage body storage device described in Patent Document 1, when the number of remaining parts in the parts mounting device is low, the parts storage body storage device is instructed to take out the parts storage body for storing the parts. .. Upon receiving the delivery instruction, the parts storage body storage device starts shipping the parts storage body. Then, the parts storage body storage device transfers the parts storage body to the take-out position and waits for the operator to receive the parts storage body. Here, the problem is that the operating status of the parts storage body storage device, that is, the status is not notified to the operator. That is, in the conventional device, the worker who works at a position away from the parts storage body storage device is not informed of anything about the start or completion of delivery of the parts storage body in the parts storage body storage device. .. Therefore, it is necessary for the worker to interrupt the work as appropriate and move to the parts storage body storage device to check the status of the parts storage body storage device. This is one of the main factors that reduce work efficiency.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a parts storage body storage device, a parts supply management system, and a parts supply management method for efficiently performing parts supply work.

The first aspect of the present invention is a parts storage body storage device, which is a storage unit for storing a plurality of parts storage bodies for storing parts, and a parts storage device for storing parts requested to be replenished to the parts mounting device. The status acquisition unit acquires the transfer unit that selectively transfers the body from the storage unit to the delivery position, the status acquisition unit that acquires status information indicating the operating status, and the external device provided apart from the delivery position.

It is characterized in that the status information received in is notified to the worker.

Further, in the third aspect of the present invention, the worker mounts the parts storage body selectively delivered in the parts storage body storage device for storing a plurality of parts storage bodies containing the parts from the parts storage body storage device. It is a parts supply management method that manages parts supply work by carrying it to the device and supplying parts to the parts mounting device. It is characterized by including a process of notifying an operator of status information at a position away from the device.

In the invention configured in this way, status information indicating the operating status of the parts storage body storage device is transmitted, and the position information away from the parts storage body storage device is notified. Therefore, the operator can grasp the operating status of the parts storage body storage device without moving to the parts storage body storage device. As a result, the worker can receive the parts storage body in which the parts requested to be replenished to the parts mounting device are stored at a reasonable timing, and the efficiency of parts replenishment can be improved.

Here, the timing at which the storage-side communication unit transmits the status information is arbitrary, and for example, the component storage unit storage device may transmit the status information to an external device such as a management control device at regular intervals. However, in this case, the status information may be transmitted at a timing when the status information is not required. Therefore, for example, the storage side communication unit may be configured to transmit status information in response to a status request from an external device. As a result, the status information is efficiently notified at the timing when it is highly necessary.

In addition, the transfer unit starts transferring from the storage unit of the parts storage body, which is the target of the delivery instruction, to the delivery position in response to the delivery instruction of the parts storage body from the external device, and the communication unit on the storage side starts the transfer of the parts storage body to the delivery position. It may be configured to send the status information indicating the start of delivery to an external device to notify the start of delivery.

It may be configured to send to to notify the completion of delivery. This makes it possible to promptly notify the operator that the preparation for parts supply is completed.

In addition, when the elapsed time from the start of delivery of the parts storage body exceeds a certain period of time, the transfer unit interrupts the delivery of the parts storage body that is the target of the delivery instruction, and the storage side communication unit stores the parts. It may be configured to send status information indicating the suspension of delivery of the body to an external device to notify the suspension of delivery. It is possible to prevent the operating condition in which the parts storage body is not properly delivered from being continued. In addition, it is possible to reliably notify the operator that such an inappropriate operating condition has occurred.

In addition, the reason for the suspension of delivery may be included in the status information indicating the suspension of delivery of the parts storage body, so that the worker can grasp not only the fact that the delivery is suspended but also the reason for the suspension. It will be possible to respond appropriately.

In addition, when the parts storage body that is the target of the delivery instruction is not stored in the storage unit, the storage side communication unit provides status information indicating that there is no parts storage body that is the target of the delivery instruction. It may be configured to be sent to and notified. As a result, the operator can quickly grasp that the parts storage body, which is the target of the delivery instruction, is in the non-storage state without moving to the vicinity of the parts storage body storage device.

Further, a storage information storage unit for storing storage information regarding a plurality of parts storage bodies stored in an external parts storage is further provided, and the storage side communication unit has a parts storage unit corresponding to a delivery instruction in the parts storage. When it is stored, it may be configured to send status information indicating storage of the parts storage body in the parts storage to an external device to notify it. As a result, the worker can quickly grasp that the parts storage body, which is the target of the delivery instruction, is stored in the parts storage without moving to the vicinity of the parts storage. Further, the status information indicating the storage of the parts storage body in the parts storage may include the storage position of the parts storage body in the parts storage, and the parts storage body corresponding to the delivery instruction is stored in the above storage position. Is notified to the worker. Therefore, the worker can efficiently take out the parts storage body corresponding to the delivery instruction from the parts storage and carry it to the parts mounting device.

Further, in order to notify the operator of the status information, a monitor may be arranged in the vicinity of the component mounting device to display the status information on the monitor. Further, the status information may be displayed on the mobile terminal by wirelessly communicating with the mobile terminal carried by the worker. By adopting these display methods, the operator can easily check the operating status of the parts storage body storage device.

Further, when the parts supply work for the plurality of parts mounting devices is shared by a plurality of workers, the status information displayed on the mobile terminal may be different according to the parts supply work shared by each worker. As a result, only the status information related to the parts replenishment work that each worker is in charge of is displayed on the mobile terminal carried by each worker. As a result, it is possible to accurately grasp and execute the parts replenishment work to be performed by oneself, and it is possible to improve the efficiency of parts replenishment.

According to the present invention, since status information indicating the operating status of the parts storage body storage device is transmitted to notify the position away from the parts storage body storage device, a plurality of parts storage bodies containing parts are stored. It is possible to selectively carry the parts storage body containing the parts requested to be replenished from the storage unit to the parts mounting device to the delivery position and efficiently replenish the parts to the parts mounting device.

The status information that can be acquired in this embodiment is as shown in FIG.

FIG. 6 is a diagram showing the relationship between the status and the contents of the reel storage device. The left column of the figure describes the type of status, and the right column describes the contents of each status. That is, the relationship between status and status content is
・ Reel storage device is warehousing reel ・ Reel storage device is warehousing reel ・ Reel storage device is warehousing ・ Reel storage device Is in an abnormal state-Initialization ... Reel storage device is in initialization operation-Preparation completed ... Ready state-Starting delivery ... Reel storage device has started shipping reel -Delivery completed ... Reel delivery from the reel storage device completed-No parts ... No spare parts in the reel storage device-Parts storage ... Replenishment parts exist in the parts storage. The "replenishment component" means a component for which supply to the component mounting devices MC1 to MC3 is requested.

Upon receiving the status notification, the management control device 200 acquires the status of the reel storage devices PT1 to PT3 and displays information on parts supply on the large monitor 600 and the mobile terminal 400. In FIG. 5 (FIGS. 7 to 9 described later), as information regarding parts supply,
・ Production line L1, which requires parts supply,
・ Parts mounting devices MC1 to MC3, which require parts supply,
・ Types of parts (replenishment parts) that are required to be replenished,
-Reel storage devices PT1 to PT3 that store the reel R that stores spare parts.
-Status of the reel storage devices PT1 to PT3,
-The estimated time required for shipping, that is, the remaining shipping time, is displayed in a table format. Therefore, the worker OP, who is mainly working on the production line L1, does not have to move to the storage area where the reel storage devices PT1 to PT3 are arranged. Information can be grasped all at once.

Further, in the parts supply management system 100, the production line control device 300 periodically collects information about the parts on the production line L1 and transmits the information to the management control device 200 (parts information notification). In the management control device 200, the system management control unit 210 acquires the parts information notification, and examines whether or not the number of remaining parts in the production line L1 is reduced and the parts need to be replenished. Then, when it is determined that replenishment is necessary, the system management control unit 210 determines that the parts determined to be replenished, that is, the reel R for accommodating the replenishment parts (hereinafter referred to as "replenishment reel R"). ) Is transmitted from the storage source (reel storage devices PT1 to PT3) to the reel storage device PT1 to issue the reel R (delivery instruction).

Upon receiving the delivery instruction, the reel storage device PT1 starts the delivery of the reel R at the specified storage source. For example, when the storage source of the replenishment reel R is the reel storage device PT1, the reel storage device PT1 specifies the storage position of the replenishment reel R in the reel storage device PT1 and the replenishment reel as shown in FIG. The time required for the delivery of R, the so-called remaining delivery time, is predicted. Then, the reel storage device PT1 transmits to the management control device 200 that the delivery has started with the remaining delivery time (delivery start notification). When the storage source of the replenishment reel R is the reel storage devices PT2 and PT3, the storage position of the replenishment reel R is specified and the remaining delivery time is predicted by the reel storage devices PT2 and PT3. Information regarding the delivery time and the start of delivery is transmitted to the management control device 200 via the master, that is, the reel storage device PT1 (delivery start notification).

Upon receiving the delivery start notification, the management control device 200 updates the display contents of "status" and "remaining delivery time" among the display items on the large monitor 600 and the mobile terminal 400 based on the received information (update of status, etc.). .. For example, as you can see by comparing the upper left and middle left figures in Fig. 5, the "status" section is updated from "waiting" to "delivering" and the "remaining delivery time" section is "-". Is updated to "30 seconds". Therefore, the worker OP working on the production line L1 can see the large monitor 600 and the mobile terminal 400, and can replenish the reel R without moving to the storage area where the reel storage devices PT1 to PT3 are arranged. It can be confirmed that the replenishment reel R is scheduled to be delivered to the warehousing / delivery position 512 at least about 30 seconds after the warehousing is started.

In the reel storage device PT1 that has notified the start of delivery, the reel transfer unit 520 (FIG. 2) moves to the storage position of the replenishment reel R and holds the replenishment reel R following the identification of the storage position of the replenishment reel R. do. Then, the reel transfer unit 520 moves to the warehousing / delivery position 512 while holding the replenishment reel R, and then releases the holding of the replenishment reel R. In this way, the replenishment reel R is transferred to the warehousing / delivery position 512. Upon confirming the completion of delivery of the replenishment reel R in this way, the reel storage device PT1 determines that the delivery of the replenishment reel R has been completed and the worker OP can receive the replenishment reel R. Send to (Notice of completion of delivery).

Upon receiving the delivery completion notification, the management control device 200 updates the display contents of "status" and "remaining delivery time" among the display items on the large monitor 600 and the mobile terminal 400 based on the delivery completion notification (status, etc.). (Update), for example, as shown in FIG. 5, a message such as "The delivery of the replenishment reel has been completed" is additionally displayed on the large monitor 600 and the mobile terminal 400. Therefore, the worker OP working on the production line L1 can see the large monitor 600 and the mobile terminal 400, and can replenish the reel R without moving to the storage area where the reel storage devices PT1 to PT3 are arranged. Can be confirmed to have been delivered to the warehousing / delivery position 512 of the reel storage device PT1. Then, the worker OP may move to the storage area at his / her convenience, receive the replenishment reel R, and carry it to the component mounting device MC1 displayed on the large monitor 600 and the mobile terminal 400 to replenish the components. can.

As described above, according to the present embodiment, status information indicating the operating status of the reel storage devices PT1 to PT3 is transmitted to the management control device 200 for notification, and is displayed on the large monitor 600 and the mobile terminal 400. Therefore, the operator OP can grasp the operating status of the reel storage devices PT1 to PT3 at a position away from the reel storage devices PT1 to PT3 without moving to the storage area by checking the displayed contents. As a result, the worker OP can go to the storage area at a reasonable timing and receive the reels containing the parts to be replenished in the parts mounting devices MC1 to MC3, that is, the replenishment reel R. In addition, the efficiency of parts supply work can be improved. Moreover, when the management control device 200 makes a status request to the reel storage device PT1, the communication unit 590 of the reel storage device PT1 transmits the status information. Therefore, the status information is notified at the timing when the operating status of the reel storage devices PT1 to PT3 is desired to be grasped, and the notification efficiency can be improved.

Further, when the management control device 200 determines that the parts mounting devices MC1 to MC3 need to be replenished with parts, the management control device 200 transmits a delivery instruction of the replenishment reel R to the reel storage device PT1. Then, in response to this, the reel storage device that stores the replenishment reel R immediately starts warehousing of the replenishment reel R from the storage unit 530 to the warehousing / delivery position 512. Therefore, the time required for parts replenishment work can be shortened. This delivery start is transmitted from the reel storage device PT1 to the management control device 200, displayed on the large monitor 600 and the mobile terminal 400 via the management control device 200, and the delivery start is grasped at a position away from the reel storage devices PT1 to PT3. can do. Moreover, in the present embodiment, since the remaining warehousing time is displayed on the large monitor 600 and the mobile terminal 400 at the same time as the warehousing start, the worker OP who sees this easily predicts the receivable time of the replenishment reel R. It is easy to make the setup of the current work and parts supply. As a result, the efficiency of parts supply work can be improved.

Further, when the delivery is completed, the reel storage device PT1 transmits the delivery completion to the management control device 200, and the delivery completion is displayed on the large monitor 600 and the mobile terminal 400 via the management control device 200, and the positions away from the reel storage devices PT1 to PT3. The worker OP can quickly grasp the completion of delivery. As a result, the worker OP can shift to the parts replenishment work after confirming the completion of delivery, and the parts replenishment work can be performed at a reasonable timing.

By the way, in the first embodiment, the reel storage devices PT1 to PT3 perform the warehousing process of the replenishment reel R in response to the warehousing instruction. The delivery process of the replenishment reel R corresponding to the instruction cannot be performed. The same applies when an abnormality has occurred in the reel storage devices PT1 to PT3. When the reel storage devices PT1 to PT3 are in these operating states, the reel storage devices PT1 to PT3 do not shift to the warehousing completion state indefinitely, and the worker OP keeps waiting for the completion of the warehousing process.

Therefore, if the delivery of the replenishment reel R cannot be completed within a certain period of time after receiving the delivery instruction, the status information indicating this is transmitted from the reel storage device PT1 to the management control device 200 to notify the management control device 200. It is desirable to do (second embodiment). Hereinafter, the second embodiment of the present invention will be described with reference to FIG. 7.

FIG. 7 is a diagram showing an example of a parts supply management operation in a parts supply management system that manages parts supply using the second embodiment of the parts storage body storage device according to the present invention. In the second embodiment, the configuration of the entire parts supply management system including the reel storage devices PT1 to PT3 is the same as that of the first embodiment, but the operation described below is additionally carried out. Therefore, in the following, the additional parts will be mainly described, and the same configuration and operation will be omitted.

Also in the second embodiment, similarly to the first embodiment, the reel storage device PT1 transmits and notifies the status information of all reel storage devices PT1 to PT3 in response to the status request from the management control device 200. Further, in response to the delivery instruction from the management control device 200, a part or all of the reel storage devices PT1 to PT3 start the delivery process of the replenishment reel R, and the reel storage device PT1 transmits status information indicating the start of delivery. Notify. Here, for the sake of easy understanding of the content of the invention, the description will be continued on the assumption that the reel corresponding to the delivery instruction, that is, the replenishment reel R is delivered in the reel storage device PT1.

The operation up to this point is the same as that of the first embodiment, but in the second embodiment, the reel storage device PT1 starts counting the elapsed time at the same time as the start of delivery. Then, even when the state in which the warehousing process is not completed exceeds a predetermined fixed time (a sufficient time for transferring the replenishment reel R from the storage unit 530 to the warehousing / delivery position 512), the warehousing is completed. When not, the transfer of the replenishment reel R by the reel transfer unit 520 is stopped. That is, the reel storage device PT1 interrupts the warehousing work. Further, in the reel storage device PT1, the status acquisition unit 543 acquires status information including the reason for interruption of the delivery work, and the communication unit 590 transmits it to the management control device 200 to notify the interruption and the reason for the interruption of the delivery work. ..

Upon receiving these, the management control device 200 updates the display contents of "status" and "remaining delivery time" among the display items on the large monitor 600 and the mobile terminal 400 based on the delivery interruption notification (update of status and the like). At the same time, for example, as shown in FIG. 7, a message such as "Reason for interruption of delivery: Abandonment of the previous delivery reel" is additionally displayed on the large monitor 600 and the mobile terminal 400. Therefore, the worker OP working on the production line L1 can see the large monitor 600 and the mobile terminal 400 without moving to the storage area where the reel storage devices PT1 to PT3 are arranged, but the reel storage device PT1. It can be confirmed that the reason for the interruption of the delivery work has occurred in. Then, the worker OP can perform the work corresponding to the reason for the interruption and eliminate the interruption of delivery.

As described above, according to the second embodiment, the delivery of the replenishment reel R by the reel transfer unit 520 is interrupted as the elapsed time from the start of delivery of the replenishment reel R exceeds a certain time. There is. Therefore, it is possible to reliably prevent the replenishment reel R from being delivered under an inappropriate operating condition. In addition, such an operation status can be promptly notified to the worker OP. Further, since the status information includes the reason for the suspension of delivery, the worker OP can accurately grasp not only the fact that the delivery is suspended but also the reason for the suspension. Then, the interruption of delivery can be resolved at an early stage by an appropriate response by the worker OP.

In the first embodiment and the second embodiment, the storage unit 530 stores various types of reels R, and the reel corresponding to the delivery instruction, that is, the replenishment reel R is at least one of the reel storage devices PT1 to PT3. The replenishment reel R is delivered and suspended on the premise that it is stored in one place. However, the replenishment reel R may not be stored in any of the reel storage devices PT1 to PT3, and a state in which delivery cannot be performed may occur. In order to deal with this, it is desirable to transmit the status information indicating the status information from the reel storage device PT1 to the management control device 200 to notify the management control device 200. Further, although the replenishment reel R is not stored in the reel storage devices PT1 to PT3, it may be stored in the parts storage PW. Therefore, it is necessary for the worker OP to move to the parts storage PW, and to find out whether or not the replenishment reel R is stored in the parts storage PW, and further to find the storage position. In view of these circumstances, when a delivery instruction is received from the management control device 200, the replenishment reel R in the reel storage devices PT1 to PT3 is stored / non-stored and the replenishment reel R in the parts storage PW is stored before the delivery is started. It is desirable to automatically confirm the storage / non-storage of the reel (third embodiment). Hereinafter, the third embodiment of the present invention will be described with reference to FIG.

FIG. 8 is a diagram showing an example of a parts supply management operation in a parts supply management system that manages parts supply using the third embodiment of the parts storage body storage device according to the present invention. In the third embodiment, the configuration of the entire parts supply management system including the reel storage devices PT1 to PT3 is the same as that of the first embodiment or the second embodiment, but the operation described below is additionally implemented. Therefore, in the following, the additional parts will be mainly described, and the same configuration and operation will be omitted.

Also in the third embodiment, as in the first embodiment and the second embodiment, the reel storage device PT1 transmits the status information of all reel storage devices PT1 to PT3 in response to the status request from the management control device 200. Notice. On the other hand, when a delivery instruction is given to the reel storage device PT1 from the management control device 200, the reel corresponding to the delivery instruction, that is, the replenishment reel R is released from the reel storage devices PT1 to before starting the delivery process of the replenishment reel R. The reel storage device PT1 determines whether or not it is stored in the PT3. Here, when the storage of the replenishment reel R is confirmed, the delivery of the replenishment reel R is started as in the first embodiment and the second embodiment.

On the other hand, when it is confirmed that the replenishment reel R is not stored in any of the reel storage devices PT1 to PT3, the reel storage device PT1 replenishes the replenishment reel based on the storage information stored in the reel storage information storage unit 580. It is determined whether or not R is stored in the parts storage PW. Here, if the storage of the replenishment reel R cannot be confirmed, the illustration in FIG. 8 is omitted, but in the reel storage device PT1, the replenishment reel R is also a part of the reel storage devices PT1 to PT3. Status information indicating that it does not exist in the storage PW, that is, "no parts" is transmitted to the management control device 200 to notify the management control device 200. Then, in response to this, the management control device 200 updates the display of the large monitor 600 and the mobile terminal 400 to the content of notifying "no parts". Therefore, the worker OP working on the production line L1 does not have to move to the storage area where the reel storage devices PT1 to PT3 and the parts storage PW are arranged by looking at the large monitor 600 and the mobile terminal 400. It can be recognized that spare parts do not exist and that spare parts need to be arranged immediately.

On the other hand, when the storage of the replenishment reel R can be confirmed, as shown in the lower right portion of FIG. 8, the reel storage device PT1 indicates that the replenishment reel R is stored in the parts storage PW. The status information including the storage position is transmitted to the management control device 200 to notify the management control device 200. Then, the management control device 200 that has received this updates the display contents of "storage device", "status", and "remaining delivery time" among the display items on the large monitor 600 and the mobile terminal 400 based on the above notification. Along with (update of status and the like), for example, as shown in FIG. 8, a message such as "storage position in the parts storage: shelf (2-1)" is additionally displayed on the large monitor 600 and the mobile terminal 400. Therefore, the worker OP working on the production line L1 moves to the parts storage PW, takes out the replenishment reel R from the shelf (2-1) by looking at the large monitor 600 and the mobile terminal 400, and mounts the parts. It is carried to an apparatus (in the case shown in FIG. 8, the component mounting apparatus MC1) to supply components.

As described above, according to the third embodiment, it is automatically determined whether or not the replenishment reel R is stored in the parts storage PW based on the storage information stored in the reel storage information storage unit 580. Can be done. Further, along with the storage of the replenishment reel R in the parts storage PW, the status information including the storage position is transmitted to the management control device 200, displayed on the large monitor 600 and the mobile terminal 400, and notified to the operator OP. Therefore, the worker OP can quickly grasp that the reel that is the target of the delivery instruction, that is, the replenishment reel R is stored in the parts storage PW without moving to the parts storage PW. ing. Moreover, the storage position of the replenishment reel R in the parts storage PW is also displayed on the large monitor 600 and the mobile terminal 400, and is notified to the operator OP. Therefore, the worker OP in the parts storage PW can efficiently take out the replenishment reel R from the parts storage PW and carry it to the parts mounting devices MC1 to MC3.

As described above, in the first embodiment to the third embodiment, the reel R corresponds to an example of the "parts storage body" of the present invention, and in particular, the replenishment reel R corresponds to the "parts mounting device" of the present invention. It corresponds to an example of "a parts storage body that stores parts for which replenishment is requested" and "a parts storage body that is subject to a delivery instruction". Further, the management control device 200 corresponds to an example of the "external device" of the present invention. Further, the warehousing / delivery position 512 corresponds to an example of the "delivery position" of the present invention. Further, the communication units 590 and 250 correspond to examples of the "storage side communication unit" and the "management side communication unit" of the present invention, respectively. Further, the reel storage position storage unit 580 corresponds to an example of the "storage information storage unit" of the present invention.

The present invention is not limited to the above-described embodiment, and various modifications can be made other than those described above as long as the present invention is not deviated from the gist thereof.

Even in the case of sharing, all status information and the like may be displayed collectively on the large monitor 600 and the mobile terminal 400. Further, as shown in FIG. 9, of the two workers OP1 and OP2, the worker OP1 is in charge of the parts supply work for the parts mounting devices MC1 and MC2, and the worker OP2 is in charge of the parts supply work for the parts mounting device MC3. In this case, the display content on each mobile terminal 400 may be different. That is, while only the status information related to the component mounting devices MC1 and MC2 is selectively displayed for the mobile terminal 400 of the worker OP1, the status related to the component mounting device MC3 is displayed for the mobile terminal 400 of the worker OP2. Only information may be selectively displayed. In this way, the mobile terminal 400 carried by each worker OP1 and OP2 displays only the status information related to the parts replenishment work that he / she is in charge of, so that each worker OP1 and OP2 can perform the parts that he / she should perform. It is possible to accurately grasp the replenishment work and improve the efficiency of parts replenishment. Even in this case, it is desirable that the large monitor 600 collectively displays the status information and the like related to all the component mounting devices MC1 to MC3.

Further, in the first embodiment, the status notification is appropriately executed between the delivery start notification and the delivery completion notification to notify the management control device 200 of the progress status of the delivery operation, and the large monitor 600 and the mobile terminal 400 are displayed. May be updated. As a result, the worker OP can visually confirm the progress of the delivery operation of the replenishment reel R, which is preferable.

Further, in the above embodiment, status information, messages, and the like are displayed on the large monitor 600 and the mobile terminal 400 to visually notify the workers OP, OP1, and OP2, but together with or instead of the display. May be notified by voice.

Further, in the above embodiment, the reel storage device PT1 is made to function as a master in order to collectively control the three reel storage devices PT1 to PT3, but the status information is independently provided to the management control device 200. May be configured to send.
