Description

The present specification relates to a parts warehouse that stores reels on which carrier tapes containing a plurality of parts are wound.

2. Description of the Related Art A technology for mass-producing substrate products by performing board-to-board work on a board on which printed wiring has been applied is widespread. Furthermore, it is common to configure a component mounting line by arranging a plurality of component mounting machines that perform component mounting work as board-related work. Many component mounters supply components using carrier tapes that contain multiple components. This carrier tape is procured in a reel-wound state and stored in a parts warehouse. Then, the reels are taken out from the parts warehouse according to the progress of the mounting work and the changeover work when changing the board type. Patent Documents 1 and 2 disclose technical examples related to this type of parts warehouse.

Patent Literature 1 discloses an automatic warehouse management device that utilizes vacant time for entering and leaving the warehouse based on the delivery schedule, and moves articles with earlier scheduled delivery dates and times to shelves closer to the delivery station. According to this, it is possible to shorten the time from the delivery request to the completion of delivery.

Further, Patent Document 2 discloses an automated warehouse in which the shelves of an automated warehouse are divided into a short-term zone close to a delivery station and a medium- to long-term zone distant from the delivery station, and the planned number of deliveries for one day is set as the safety stock number, and stored items are moved from the medium- to long-term zone to the short-term zone during a specified time period such as nighttime or lunch break. According to this, the shortage from the safety stock quantity is replenished in the short-term zone during the time when the load is light, so the waiting time until delivery can be shortened.

By the way, the technical examples of Patent Literature 1 and Patent Literature 2 are preferable in that the time required for shipping individual articles can be shortened. However, in the parts warehouse, if the individual reels are separately delivered, the delivery operation becomes frequent, which is troublesome for the operator. Furthermore, every time the product is delivered, it takes time and effort to take out the reel and transport it to the component mounting machine or the component mounting line. Note that the reel is not necessarily directly transported to the component mounting machine, and may be transported to the setup work area and loaded into the feeder device.

An object of the present specification is to provide a parts warehouse capable of streamlining the reel delivery operation and the subsequent transport operation.

The present specification includes a warehouse housing, an entrance/exit provided in the warehouse housing for loading/unloading a reel around which a carrier tape containing a plurality of components is wound, and a carrier case capable of storing the plurality of reels, a storage unit provided inside the warehouse housing and having a plurality of storage positions for storing the reel and the carrier case, a transport operation unit for transporting the reel and the carrier case between the entrance/exit and the storage position, and a transport operation unit for transporting the reel and the carrier case between the storage position and the entrance/exit. and a storage operation unit for storing in a parts warehouse.

In the parts warehouse disclosed herein, a plurality of reels can be stored in a carrier case inside the parts warehouse. Therefore, by unloading the carrier case, a plurality of reels can be unloaded at the same time, and the unloading operation can be made efficient. Furthermore, since a plurality of reels can be transported at the same time by transporting the carrier case to the place where the post-process is performed, transport work can be made more efficient. In addition, since reels can be quickly supplied, it contributes to the improvement of production efficiency of printed circuit board products.

1. Device Configuration of Parts Warehouse 1 of First Embodiment The device configuration of the parts warehouse 1 of the first embodiment will be described with reference to FIGS. 1 to 4. FIG. The parts warehouse 1 receives, stores, and delivers a reel 81 wound with a carrier tape containing a plurality of parts and a carrier case 85 capable of accommodating the plurality of reels 81 . The reel 81 is used in a component mounting line 9 in which one component mounting machine or a plurality of first to fourth component mounting machines (91 to 94) are lined up (see FIG. 5).

As shown in FIGS. 2 and 3, the reel 81 is disc-shaped and has a through hole 82 in its center. A component type label 83 is attached to the reel 81 when it is procured. The component type label 83 indicates, for example, the type and characteristics of the component accommodated in the carrier tape, the expiration date, the width of the carrier tape, the size of the reel 81, the production lot number, and the like. The component type label 83 is produced and attached by the component supplier. A bar code, a two-dimensional code, a number string, or the like is used as the part type label 83 .

The board product manufacturer manages the procured reels 81 by affixing reel identification labels 84 afterwards. The reel identification label 84 identifies an individual reel 81 . The reel identification label 84 may be associated with additional information desired by the manufacturer. As additional information, information possessed by the component type label 83 can be exemplified. According to this, if the reel identification label 84 is read in subsequent operations and works, it becomes unnecessary to read the part type label 83 each time.

As shown in FIGS. 3 and 4, the carrier case 85 is shaped like a box that opens upward. The depth of the carrier case 85 is appropriately set according to the number of reels 81 to be accommodated. An axial rod 86 extending vertically is provided in the center of the carrier case 85 . The shaft rod 86 engages with the through holes 82 of the plurality of reels 81 . As a result, the carrier case 85 accommodates the plurality of reels 81 while stacking them vertically. A case identification label 87 is affixed to the collar portion of the upper edge of the carrier case 85 . The case identification label 87 identifies the individual carrier case 85 . Note that the carrier case 85 may have a shape different from that described above. For example, the carrier case 85 may have a cylindrical shape that opens upward and the shaft rod 86 may be omitted.

The parts warehouse 1 includes a warehouse housing 2, an entrance/exit port 3, a reel storage section 4R, a case storage section 4C, a holding/moving section 5, a warehouse control section 7 (see FIG. 5), and the like. The warehouse housing 2 is formed in a rotationally symmetrical shape with a vertical axis AX. In the first embodiment, as shown in FIGS. 1 to 3, the warehouse housing 2 is formed in a vertical cylindrical shape. The inside of the warehouse housing 2 has a three-stage structure consisting of an upper stage, a middle stage, and a lower stage.

Seven reel storage units 4R are arranged in the upper row of the warehouse housing 2 in the circumferential direction. A loading/unloading port 3 and six reel storage units 4R are arranged in the middle of the warehouse housing 2 in the circumferential direction. Four reel storage units 4R and three case storage units 4C are arranged in the lower row of the warehouse housing 2 in the circumferential direction. The positions of the three case storage sections 4C are directly below the entrance/exit 3 and on both left and right sides thereof. Therefore, a total of 17 reel storage units 4R and 3 case storage units 4C are provided. Note that the number of storage units (4R, 4C) may be other than the above. Furthermore, the arrangement and structure of the storage units (4R, 4C) inside the warehouse housing 2 can be modified in various ways.

The entrance/exit 3 is arranged at an intermediate height on the front surface of the warehouse housing 2 . The loading/unloading port 3 is a place where the reel 81 and the carrier case 85 are loaded and unloaded. By locating the entrance/exit 3 at an intermediate height, the average value of the transportation distances to all the storage racks 42 is minimized. Therefore, the average value of the time required for entering the warehouse and the average value of the time required for leaving the warehouse are also minimized. It is also possible to arrange the entrance at the middle height of the front surface of the warehouse housing 2 and separately arrange the exit entrance at the middle height of the rear surface of the warehouse housing 2 . The entrance/exit 3 is composed of an opening 31, a stand 32, a camera 34, a label making/pasting machine 35, and the like.

The opening 31 is formed in a horizontally long rectangular shape at an intermediate height position on the front surface of the warehouse housing 2 . A stand 32 is provided deep inside the lower edge of the opening 31 . The stand 32 is configured including two plate members separated left and right. The two plates are arranged with a slight inclination angle so that the front side near the opening 31 is low and the back side is high. A lower arm 562 of the gripping portion 56, which will be described later, can enter between the two plates. A positioning member 33 extending in the left-right direction is provided in the upper part of the front side of the stand 32 . The positioning member 33 stabilizes the mounting positions of the reel 81 and the carrier case 85 mounted on the mounting table 32 .

The camera 34 is arranged at the back of the upper edge of the opening 31 and faces downward to take an image. The camera 34 has a light source for illumination, and has a function of automatically adjusting imaging conditions according to an object to be imaged. The camera 34 images the reel 81 on the stand 32 and reads the part type label 83 and the reel identification label 84 . Also, the camera 34 images the carrier case 85 on the stand 32 and reads the case identification label 87 . Furthermore, the camera 34 may have a function of determining a plurality of types of sizes of the reel 81 and the carrier case 85, and confirming the placed position and orientation.

The label making and applying machine 35 is arranged further behind the camera 34 at the upper edge of the opening 31 . The label producing and pasting machine 35 produces reel identification labels 84 according to the instructions. The label making and pasting machine 35 further moves the produced reel identification label 84 to the lower pasting execution position and sticks it to the reel 81 positioned below.

The internal configuration of the 17 reel storage units 4R is generally the same. Each of the reel storage units 4R is composed of a storage container 41 and five storage racks 42. As shown in FIG. The storage container 41 is formed in a box shape that opens sideways toward the axis AX. The five storage racks 42 are arranged at regular intervals in the vertical direction inside the storage container 41 . The storage shelf 42 is made of two plate members separated left and right like the stand 32 and has the same inclination angle as the stand 32. - 特許庁Storage shelf 42 is one form of storage position for storing reels 81 . Since the storage shelf 42 and the table 32 have an inclination angle, the reel 81 is prevented from slipping down due to the influence of vibration or the like.

The parts warehouse 1 stores reels 81 in a total of 85 storage racks 42 of 17 reel storage units 4R. An actual parts warehouse can store a larger number of reels 81 . Each storage shelf 42 is assigned an identification number and managed. The identification number is, for example, a combination of a number specifying the storage container 41 and a number representing the arrangement height of the storage shelf 42 .

The internal configurations of the three case storage units 4C are generally the same. Each of the case storage sections 4C is composed of a storage container 41 and two storage racks 42 having the same shape as the reel storage section 4R. The height positions of the two storage racks 42 correspond to the lowest and third storage racks 42 from the bottom of the reel storage section 4R. Therefore, the distance between the storage racks 42 in the vertical direction is increased, and the storage racks 42 can store the tall carry case 85 . A maximum of six carrier cases 85 are stored in the three case storage sections 4C. Each of the storage racks 42 is assigned an identification number and managed in the same manner as the reel storage section 4R.

Note that the storage shelf 42 is detachable from the storage container 41 . The operation of attaching and detaching the storage shelf 42 is performed through an openable and closable hand hole (not shown) provided in the warehouse housing 2 . Therefore, the reel storage section 4R can be changed to the case storage section 4C, or vice versa. Furthermore, the storage container 41 can be moved or replaced with a spare part.

The holding/moving unit 5 moves inside the warehouse housing 2 while holding the reel 81 and the carrier case 85 . The holding/moving unit 5 serves as both a transport operation unit and a storage operation unit. The transport operation unit transports reels 81 and carrier cases 85 between the entrance/exit 3 and the storage racks 42 of the storage units (4R, 4C). The storage operation section stores a plurality of reels 81 in a carrier case 85 inside the warehouse housing 2 .

The holding/moving unit 5 includes two elevating shafts 51, a bearing unit 52, a rotary driving unit 53, an elevating/rotating unit 54, an elevating driving unit 55 (see FIG. 5), a gripping unit 56, and the like. The two elevating shafts 51 extend in the vertical direction and are arranged symmetrically across the axis AX. In FIG. 1, the two lifting shafts 51 are overlapped in the front-back direction of the page, and only one is shown.

The bearing portion 52 is arranged on the bottom plate 21 of the warehouse housing 2 . The bearing portion 52 supports the lower ends of the two elevation shafts 51 and allows the two elevation shafts 51 to revolve around the axis AX. The rotation drive unit 53 is arranged under the top plate 22 of the warehouse housing 2 . The rotary drive unit 53 supports the upper ends of the two elevation shafts 51 and drives the two elevation shafts 51 to revolve around the axis AX.

The up-and-down rotation part 54 is arranged in a central area of the warehouse housing 2 where the storage parts (4R, 4C) do not exist, and is attached across the two up-and-down shafts 51 . As the two elevation shafts 51 revolve, the elevation rotation portion 54 rotates around the axis AX. An elevation driving section 55 is attached to the elevation rotation section 54 . The elevation rotating section 54 is driven by the elevation driving section 55 to ascend and descend along the two elevation shafts 51 . The up-and-down rotating portion 54 is elongated in the front-rear direction (horizontal direction in FIG. 1) and has the same angle of inclination as the table 32 and the storage shelf 42 .

The gripping portion 56 is provided on the up-and-down rotating portion 54 so as to be movable in the radial direction. The gripping portion 56 is composed of a gripping body portion 561 , a lower arm 562 , an upper arm 563 and a gripping driving portion 564 . The grip body portion 561 can move back and forth on the upper surface of the up/down rotating portion 54 . As a result, the entire gripping portion 56 moves back and forth in the radial direction around the axis AX. The lower arm 562 is attached to the lower portion of the grip body portion 561 and extends forward. The upper arm 563 is attached at a position higher than the lower arm 562 of the grip main body 561 and extends forward. The upper arm 563 can move up and down with respect to the grip main body 561 . The length of upper arm 563 is shorter than that of lower arm 562 . The lower arm 562 and the upper arm 563 have the same angle of inclination as the table 32 and the storage shelf 42 and are parallel to each other.

As shown in FIG. 1 , when the grip main body 561 is positioned at the rear end of the up/down rotation portion 54 , the tip of the lower arm 562 does not protrude from the up/down rotation portion 54 . Therefore, the lower arm 562 does not interfere with the rotation and elevation of the up-and-down rotating portion 54 . When the grip main body 561 moves forward of the up/down rotation part 54 , the lower arm 562 protrudes from the up/down rotation part 54 and enters between the two plate members that constitute the table 32 and the storage shelf 42 .

The grip driving portion 564 is provided on the upper portion of the grip body portion 561 . The grip drive unit 564 drives the upper arm 563 up and down. As a result, the distance between the lower arm 562 and the upper arm 563 in the vertical direction changes. Therefore, the lower arm 562 and the upper arm 563 can grasp the reel 81 and the carrier case 85 placed on the table 32 and the storage shelf 42 from above and below, and can release them. It is also possible to employ a configuration in which the grip body portion 561 does not move and the lower arm 562 and the upper arm 563 expand and contract in the front-rear direction.

2. Configuration Related to Control of Parts Warehouse 1 Next, a configuration related to control of the parts warehouse 1 will be described. As shown in FIG. 5 , the parts warehouse 1 has a warehouse control section 7 . Further, as shown in FIG. 2 , an operation display panel 79 is provided above the entrance/exit 3 on the front surface of the warehouse housing 2 . The operation display panel 79 includes an operation section operated by the operator and a display section for displaying information to the operator. The operation display panel 79 functions as a man-machine interface for exchanging information between the worker and the warehouse control section 7 .

The warehouse control unit 7 is a computer device that has a CPU, a storage unit, and the like and operates with software. The warehouse controller 7 controls the camera 34 and the label making and applying machine 35 . Furthermore, the warehouse control section 7 controls the rotation drive section 53 , the elevation drive section 55 , the grip body section 561 and the grip drive section 564 of the holding/moving section 5 . Furthermore, the warehouse control unit 7 includes three control function units that comprehensively control the operations of the parts warehouse 1, namely, a transport control unit 71, a storage control unit 72, and a storage position control unit 73.

The warehouse controller 7 is communicatively connected to the line controller 99 . The line control unit 99 is connected for communication with the first to fourth component mounting machines (91 to 94) constituting the component mounting line 9, respectively. The component mounting line 9 is a part of a production line for mass-producing board products by mounting components on boards. A line control unit 99 manages the progress of the mounting work of the first to fourth component mounting machines (91 to 94). In addition, the line control unit 99 manages changes in the types of board products to be produced and the types of base boards.

The transport control unit 71 controls the holding/moving unit 5 to perform the warehousing operation and the warehousing operation. More specifically, the transport control unit 71 first recognizes that the reel 81 and the carrier case 85 have been carried into the entrance/exit 3 . The presence of the reel 81 and the carrier case 85 is automatically recognized by the regular imaging operation of the camera 34 or recognized by the operator's input operation to the operation display panel 79 .

Next, the transport control unit 71 designates the identification number of the storage rack 42 and commands the holding/moving unit 5 to transport and store (instruction of warehousing operation). The designation of the identification number of the storage rack 42 is performed autonomously by the transport control unit 71 or according to the input operation to the operation display panel 79 by the operator. Thirdly, the transport control unit 71 associates the reel identification label 84 of the stored reel 81 or the case identification label 87 of the carrier case 85 with the identification number of the storage rack 42 and stores them.

The transport control unit 71 also receives requests from the line control unit 99 and requests input to the operation display panel 79 . The transport control unit 71 identifies the necessary reel identification label 84 of the reel 81 or the case identification label 87 of the carrier case 85 and further identifies the identification number of the storage rack 42 in response to the request. Next, the transport control unit 71 designates the identification number of the storage shelf 42, and commands the holding/moving unit 5 to transport the reel 81 or the carrier case 85 to the entrance/exit 3 (instruction of unloading operation). The control functions of the storage control section 72 and the storage position control section 73 will be described later.

3. Details of warehousing operation of parts warehouse 1 Next, the details of the warehousing operation of the parts warehouse 1 will be described with reference to the time-series situations and operations in FIGS. Prior to the warehousing operation, the up-and-down rotation unit 54 is driven to a position facing the entrance/exit 3, the grip main body 561 is positioned at the rear end of the up-and-down rotation unit 54, and the upper arm 563 is driven upward to increase the separation distance from the lower arm 562.

At the beginning of the warehousing operation, as shown in FIG. The placement of the reel 81 is performed by an operator. Alternatively, the placement of the reel 81 may be automatically performed by a transport robot. Next, the camera 34 performs an imaging operation (see symbol TP in FIG. 6) to read the part type label 83 and the reel identification label 84 attached to the reel 81 . Here, the reel 81 to which the reel identification label 84 is already attached is half used.

On the other hand, the reel 81 to which the reel identification label 84 is not attached is new. The warehouse control unit 7 sets an identification code to the new reel 81, and instructs the label producing/pasting machine 35 to produce a reel identification label 84 corresponding to the identification code. The warehouse control unit 7 further associates and stores the component type label 83 of the new reel 81 and the reel identification label 84 . The label production and application machine 35 that has received the command creates a reel identification label 84 and moves it to the lower application position. This results in the situation in FIG.

Next, the transport control unit 71 advances the gripping unit 56 to cause the lower arm 562 to enter below the reel 81 and the upper arm 563 to enter above the reel 81, as indicated by arrow M1 in FIG. Next, the transport control unit 71 lowers the upper arm 563 as indicated by an arrow M3 while raising the elevation rotating portion 54 as indicated by an arrow M2 in FIG. Thereby, the lower arm 562 and the upper arm 563 grip the reel 81 .

Next, the transport control unit 71 causes the gripping unit 56 to retreat while raising the up/down rotating unit 54 as indicated by an arrow M4 in FIG. 10 . As a result, the reel 81 moves closer to the label making/applying machine 35 and moves to the closest position directly below the applying position. Next, the warehouse control section 7 instructs the label making and pasting machine 35 to stick the reel identification label 84 . The label producing/pasting machine 35 that has received the command sticks the reel identification label 84 to the reel 81 as indicated by the arrow M5 in FIG. It should be noted that the attachment position of the reel identification label 84 does not have to be adjacent to the component type label 83 .

Next, the transport control section 71 further retracts the grip section 56 as indicated by an arrow M6 in FIG. As a result, the up-and-down rotation unit 54 unloads the reel 81 from the entrance/exit 3 . The transport control unit 71 controls the holding/moving unit 5 so that the reel 81 in use is directly transferred from the state of FIG. 9 to the state of FIG. 12 without going through FIGS. 10 and 11 .

After that, the transport control unit 71 drives the up/down rotation unit 54 to a position facing the storage shelf 42 to which the identification number is designated, and advances the grasping unit 56 . Thereby, the reel 81 reaches the storage rack 42 . The transport control unit 71 widens the separation distance between the lower arm 562 and the upper arm 563 and places the reel 81 on the storage shelf 42 for storage. As a result, the warehousing operation of the reel 81 is completed.

In the unloading operation of the reel 81 , the reel 81 is gripped by the storage shelf 42 and released at the entrance/exit 3 . Also, the label production and application machine 35 is not used in the shipping operation. Further, the same warehousing operation and warehousing operation are performed for the carrier case 85 as well. However, the difference is that the label making and applying machine 35 is not used, and the separation distance between the lower arm 562 and the upper arm 563 is significantly increased.

4. Control Functions of Storage Control Unit 72 and Storage Position Control Unit 73 Next, control functions of the storage control unit 72 and the storage position control unit 73 will be described. The storage control unit 72 controls the holding/moving unit 5 so that the carrier case 85 stores a plurality of reels 81 required as the mounting work progresses on the component mounting line 9 . Further, the storage control unit 72 collectively stores the plurality of reels 81 in the carrier case 85 based on the order in which the reels 81 are required. Here, the line control section 99 predicts the order of the reels 81 to be required and transmits the prediction result to the warehouse control section 7 .

The storage control unit 72 controls the holding/moving unit 5 based on the received prediction result to sequentially store the plurality of reels 81 in the carrier case 85 . Specifically, the holding/moving unit 5 repeats the operation of holding the reel 81 on the storage shelf 42 of the reel storage unit 4R, transporting it above the carrier case 85, and releasing and dropping it. Here, if the carrier case 85 can accommodate, for example, four reels 81, the required first to fourth reels 81 are accommodated in the first carrier case 851 (see FIG. 13). The required fifth to eighth reels 81 are stored in the second carrier case 852 , and the required ninth to twelfth reels 81 are stored in the third carrier case 853 .

First, the first carrier case 851 is delivered, then the second carrier case 852 is delivered, and third, the third carrier case 853 is delivered. The unloaded carrier cases (851, 852, 853) are conveyed to the component mounting line 9 by an operator or a conveying robot, and the reels 81 are taken out and used. Alternatively, the unloaded carrier cases (851, 852, 853) are conveyed to the setup work area, and the reels 81 are taken out and loaded into the feeder device. Then, this feeder device is conveyed to the component mounting line 9 and used.

In this manner, in storage based on the order of the required reels 81, the required reels 81 for the component mounting line 9 are reliably supplied. Therefore, the risk of production interruption due to parts shortage is reduced. If the required reel 81 does not exist in any of the storage racks 42 , the storage control unit 72 displays a message on the operation display panel 79 requesting the operator to store the reel 81 in question. In addition, as the carrier cases (851, 852, 853) are delivered, the storage shelf 42 of the case storage unit 4C becomes empty, so that a new carrier case 85 can be stored.

The storage position control unit 73 controls the holding/moving unit 5 so that the carrier case 85 scheduled to be delivered earlier is stored in the storage shelf 42 closer to the entrance/exit 3 . More specifically, the order of the storage racks 42 closest to the entrance/exit 3 is determined in advance based on the length of time required for unloading, not the physical distance. The time required for leaving the warehouse depends on the rotation operation time and the elevation operation time of the elevation rotation unit 54 . In the first embodiment, as shown in FIG. 13, the upper storage shelf 421 of the case storage unit 4C1 directly below the entrance/exit 3 is the closest to the entrance/exit 3, and the lower storage shelf 422 is the second closest to the entrance/exit 3.

The upper storage shelf 423 of the one case storage section 4C2 which is out of right below the entrance/exit 3 is set as the third, and the upper storage shelf 424 of the other case storage section 4C3 which is out of the right lower position is set as the fourth. Furthermore, the lower storage shelf 425 of one case storage section 4C2 is set as the fifth, and the lower storage shelf 426 of the other case storage section 4C3 is set as the sixth.

In this case, the first carrier case 851 is stored on the closest storage shelf 421 and the second carrier case 852 is stored on the second closest storage shelf 422 . A third carrier case 853 is stored in the storage shelf 423 that is the third closest. Thereafter, the fourth to sixth carrier cases 85 are respectively stored in the fourth to sixth closest storage racks (424 to 426).

After the first carrier case 85 is taken out from the storage shelf 421, the storage position control unit 73 moves the second carrier case 852 of the storage shelf 422 to the storage shelf 421 during the idle time when the storage/retrieval operation is not performed. Further, the storage position control unit 73 sequentially moves the third carrier case 853 of the storage rack 423 to the storage rack 422 . Further, the storage position control unit 73 sequentially moves the fourth and subsequent carrier cases 85 to the storage shelf 42 near the entrance/exit 3 . As a result, the carrier case 85 is always unloaded from the storage rack 421 closest to the entrance/exit 3, thereby shortening the time required for unloading.

Note that the storage control unit 72 may collectively store a plurality of reels 81 in the carrier case 85 based on the arrangement positions of the first to fourth component mounters (91 to 94) instead of the order of the required reels 81. For example, one carrier case 85 can be assigned to each of the first to fourth component mounters (91 to 94) to collectively house four reels 81 required for each.

Further, for example, the four reels 81 required by the first component mounting machine 91 and the second component mounting machine 92 can be accommodated in the first carrier case 85, and the four reels 81 required by the third component mounting machine 93 and the fourth component mounting machine 94 can be accommodated in the second carrier case 85. In this manner, storage based on the arrangement positions of the first to fourth component mounters (91 to 94) makes it less likely that the reel 81 will be mixed up when the reel 81 is taken out from the carrier case 85 and used on the component mounting line 9, and the work is easy, so workability is improved.

Furthermore, it is not always necessary to perform the unloading operation in units of carrier cases 85 . In other words, when the required timing of a certain reel 81 is greatly deviated from the required timing of other reels 81, the transport control unit 71 can control the holding/moving unit 5 so that the relevant reel 81 is released alone. In addition, the transport control unit 71 can immediately take out the reel 81 urgently needed due to the occurrence of trouble or the like. In other words, by combining the unloading operation of the carrier case 85 and the unloading operation of the reel 81, the reel 81 can be provided elastically and timely.

Further, the storage control unit 72 controls the holding/moving unit 5 so that a plurality of reels 81 required for each of the first to fourth component mounting machines (91 to 94) are collectively stored in the same carrier case 85 when the type of substrate is changed on the component mounting line 9. In a setup change operation when changing the type of board on the component mounting line 9, it is usually necessary to replace a large number of reels 81 with each other. The storage control unit 72 can acquire from the line control unit 99 information about the timing of the changeover work and the type and number of the required reels 81 .

Then, the storage control unit 72 controls the operation of storing the reel 81 into the carrier case 85 by the holding/moving unit 5 based on the acquired information. In this case, it is preferable to assign a carrier case 85 to each of the first to fourth component mounters (91 to 94). The number of carrier cases 85 to be assigned may be different for each of the first to fourth component mounters (91 to 94).

In the parts warehouse 1 of the first embodiment, a plurality of reels 81 can be stored in the carrier case 85 inside the parts warehouse 1 . Therefore, by unloading the carrier case 85, a plurality of reels 81 can be unloaded at the same time, and the unloading operation can be made efficient. Furthermore, since a plurality of reels 81 can be transported at the same time by transporting the carrier case 85 to the place where the post-process is to be performed, transport work can be made more efficient. In addition, since the reels 81 can be supplied quickly, it contributes to the improvement of the production efficiency of substrate products. It is also possible to reduce the waiting time of workers at the entrance/exit 3 .

5. Modified Example of Carrier Case Note that the carrier case 85 may be the one shown in FIGS. 14 and 15 . A large carrier case 8A shown in FIG. 14 is provided with four shafts 86. As shown in FIG. Therefore, the carrier case 8A can accommodate four times as many reels 81 as the carrier case 85 can. In this case, it is preferable to change the design of the size of the warehouse housing 2, the entrance/exit 3, and the case storage section 4C, as well as the mechanical strength and driving power of the holding/moving section 5, according to the size of the carrier case 8A.

A vertical carrier case 8B shown in FIG. 15 can accommodate five reels 81 in an upright posture. In this case, it is preferable that the reel storage section 4R has a structure in which the reels 81 are stored in an upright position, and the holding/moving section 5 also transports the reels 81 in an upright position. Further, carrier cases having shapes other than those of FIGS. 14 and 15 may be used.

6. Parts warehouse 1A of the second embodiment
Next, the parts warehouse 1A of the second embodiment will be mainly described in terms of differences from the first embodiment. As shown in FIG. 16, the parts warehouse 1A of the second embodiment includes a transport operation unit 61 and a storage operation unit 62 separately instead of the holding/moving unit 5. As shown in FIG. The device configuration and transport operation of the transport operation unit 61 are substantially the same as those of the holding/moving unit 5 of the first embodiment, and the description thereof will be omitted.

The storage operation section 62 is provided in at least one or more case storage sections 4D. The case storage section 4D is composed of a storage container 41 and one storage shelf 42. As shown in FIG. The height position of the storage shelf 42 corresponds to the lowest storage shelf 42 of the reel storage section 4R. The storage operation section 62 is provided in the upper part inside the case storage section 4D. The storage operation part 62 has a plurality of fingers 63 capable of holding the reel 81 therebetween. The storage operation section 62 is controlled by the warehouse control section 7 . The storage operation section 62 can use the finger 63 to receive the reel 81 transported by the transport operation section 61 and store it in the carrier case 85 . The storage operation unit 62 and the transport operation unit 61 repeat the above operations to collectively store the plurality of reels 81 in the carrier case 85 .

Furthermore, in the second embodiment, a carrier case 85 containing a plurality of used or new reels 81 is carried into the entrance/exit 3 . At this time, the transport operation section 61 transports and stores the carrier case 85 to the storage rack 42 of the case storage section 4D. Next, the storage operation unit 62 takes out the half-used reels 81 one by one from the carrier case 85 and transfers them to the transport operation unit 61 . The transport operation unit 61 transports the reel 81 once to the entrance/exit 3 .

Then, the camera 34 takes an image of the reel 81 and acquires the component type label 83 and the reel identification label 84 . At this time, if the reel 81 is new, a reel identification label 84 is attached by the label making and attaching machine 35 . Thereafter, similarly to the first embodiment, the reel 81 is transported to the storage rack 42 of the reel storage section 4R and stored.

The series of operations described above are performed in order for all the reels 81 in the carrier case 85 . It should be noted that the plurality of reels 81 in the carrier case 85 may be a mixture of used reels and new reels. In the second embodiment, a plurality of reels 81 can be accommodated in the carrier case 85 and collectively stored. Therefore, compared with the case where the reels 81 are stored one by one, the labor of the operator for the storage work is reduced.

7. Applications and Modifications of the Embodiment Note that the label production and application machine 35 may be replaced by a code printer that prints an identification code corresponding to the reel identification label 84 directly on the reel 81 . Further, the storage operation unit 62 of the second embodiment may be configured to include a suction cup that sucks and holds the reel 81 and an elevation driving unit that raises and lowers the suction cup. Furthermore, in order to accommodate multiple types of reels 81 of different sizes, the parts warehouses (1, 1A) may include multiple types of storage units (4R, 4C), multiple types of carrier cases 85, and the like. In addition, various applications and modifications are possible for the first and second embodiments.
