[0035] Before describing the embodiments of the present disclosure, problems in conventional devices will be briefly described.

[0036] The component management device described in Patent Document 1 has the following problem: it takes time to install or remove the component (reel) on the pallet each time the component is put in or taken out of the warehouse. In addition, a component management device that can put in or take out the component more easily and efficiently is sought.

[0037] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Figure 1 A structural diagram of a component assembly system 1 including a component management device in one embodiment of the present disclosure is shown. The component assembly system 1 includes a manufacturing line 2, a carrier processing device 3 associated with the supply of components to the manufacturing line 2, and a storage warehouse 4 associated with the storage and management of components. The manufacturing line 2 manufactures an assembly substrate JK in which components are assembled on the substrate KB by performing operations while transferring the substrate KB between a plurality of devices connected in series.

[0038] exist Figure 1 In the embodiment, the manufacturing line 2 is connected to the management computer 6 via the information management terminal 5. The management computer 6 manages the operation of each device constituting the manufacturing line 2. Figure 1 As shown in FIG. 1 , the carrier tape processing device 3 and the storage warehouse 4 are also connected to the management computer 6. The management computer 6 also manages the operations of the carrier tape processing device 3 and the storage warehouse 4. Figure 1 As shown, the management computer 6 is connected to an operator terminal 7 , and an operator of the component assembly system 1 can perform various operation inputs on the component assembly system 1 through the operator terminal 7 .

[0039] First, the manufacturing line 2 will be described. Figure 1 In the figure, the manufacturing line 2 includes a substrate supply device 11, a printing device 12, a post-printing inspection device 13, a plurality of component assembly devices 14, a post-assembly inspection device 15, a reflow device 16, a final inspection device 17 and a substrate recovery device 18.

[0040] The substrate supply device 11 sequentially supplies the substrate KB to the printing device 12 on the downstream side. The printing device 12 carries in the substrate KB supplied from the substrate supply device 11, applies a paste-like solder to the electrode formed on the surface of the substrate KB, and carries it out to the post-printing inspection device 13 on the downstream side. The post-printing inspection device 13 carries in the substrate KB carried out from the printing device 12, and inspects whether there are any parts with poor solder coating conditions by using a camera, and then carries out the substrate KB to the component assembly device 14 on the downstream side.

[0041] Each component assembly device 14 assembles components on the substrate KB carried in from the upstream side and carries it out to the downstream side. The component assembly device 14 located at the most downstream side carries out the substrate KB to the post-assembly inspection device 15 located downstream thereof. The component assembly device 14 will be described later.

[0042] The post-assembly inspection device 15 carries in the substrate KB carried out from the component assembly device 14 located on the most downstream side, and inspects whether there are any parts with poor assembly status of the components by using a camera, and then carries out the substrate KB to the reflow soldering device 16 on the downstream side. The reflow soldering device 16 carries in the substrate KB carried out from the post-assembly inspection device 15, and passes it through a reflow furnace, thereby melting and solidifying the solder to join the components to the electrodes. The final inspection device 17 carries in the substrate KB that has passed through the reflow soldering device 16, and inspects the joining status of the components to the electrodes by using a camera, and then carries it out to the substrate recovery device 18 on the downstream side. The substrate recovery device 18 receives the substrate KB carried out from the final inspection device 17 and recovers it.

[0043] Next, use Figure 2 The component assembly device 14 is described below. Figure 2 In the embodiment, a base cover 22 is provided on a base 21 of the component assembly device 14 , and a substrate conveying path 24 for conveying a substrate KB in a horizontal direction is provided in a work space 23 between the base 21 and the base cover 22 .

[0044] Feeder carriages 25 are connected to positions on both sides of the substrate conveying path 24 on the base 21. A plurality of component supply units 26 are mounted on each feeder carriage 25. Here, the component supply unit 26 is a tape feeder, and the carrier tape 27 is conveyed by a sprocket 26S, thereby supplying components BH one by one to a predetermined component supply position.

[0045] exist Figure 2 In the embodiment, an assembly head 32 is provided in the work space 23, and the assembly head 32 is moved in the horizontal plane by a head moving mechanism 31. A component suction nozzle 33 is provided in the assembly head 32 so as to extend downward. The component BH supplied by the component supply unit 26 is sucked at the lower end of the component suction nozzle 33.

[0046] After each component assembly device 14 carries in the substrate KB from the upstream side on the substrate conveying path 24 and positions the substrate KB, the assembly head 32 is operated to repeatedly perform assembly rounds while supplying the component BH using the component supply unit 26. In one assembly round, the assembly head 32 sequentially performs the actions of sucking and picking up the component BH supplied by the component supply unit 26 and assembling the component BH at a predetermined component mounting position on the substrate KB. After the assembly head 32 repeatedly performs assembly rounds and assembles all the components BH to be assembled on the substrate KB, the substrate conveying path 24 is operated to carry the substrate KB out to the downstream side.

[0047] Here, the carrier tape 27 used in the component assembly device 14 for supplying the component BH is unwound from a boxed roll 41 in this embodiment. Here, the "boxed roll 41" is obtained by storing the roll 27R of the carrier tape 27 in a box 42 (see also Figure 3 ). The boxed roll 41 is different from the conventionally used roll-attached reel roll 43 ( Figure 4 Here, the "attached reel reel 43" is obtained by holding the reel 44 with the reel 27R.

[0048] In this embodiment, the reel 44 with the reel body 43 is assumed to be Figure 5 As shown in the figure, there are two side plates 45 and a winding core 46 arranged between the two side plates 45. In the present embodiment, the winding core 46 is connected to one side plate 45. In addition, it is set to have a structure in which the two side plates 45 are connected by fitting a plurality of concave portions 46K of the winding core 46 provided on one side plate 45 with a plurality of convex portions 45T provided on the side of the other side plate 45. Therefore, when the reel 44 is disassembled in the present embodiment, the reel 44 is divided into two parts, namely, a part including one side plate 45 and a part including the other side plate 45.

[0049] Here, the box 42 of the boxed roll body 41 is described. The box 42 is as follows. Fig. 6A As shown in the figure, it has left and right side walls 51, a bottom wall 52, a front wall 53 and a rear wall 54, and has an upper opening 55 and a rear opening 56. A wireless tag 42M is attached to the outer surface of the front wall 53. On the upper part of the rear wall 54, two upper and lower protrusion bases 51B extending inward from the inner surface of one side wall 51 are provided, and the two protrusion bases 51B are provided with a belt front end holding portion 42K ( Figure 6B ).

[0050] like Fig. 7A , Figure 7BAs shown, during the storage period when the boxed roll 41 is stored or during the transportation period when the boxed roll 41 is transported, the conveying hole 27K (the hole engaged with the outer peripheral teeth of the sprocket 26S) possessed by the carrier tape 27 is inserted in advance into the tape front end retaining portion 42K provided in the box 42 and locked. It should be noted that the storage period when the boxed roll 41 is stored or the transportation period when the boxed roll 41 is transported means that the roll 27R is stored in the box 42 and is not in a state of being pulled out from the roll 27R and used by the carrier tape 27. In this embodiment, the two conveying holes 27K are inserted into the two tape front end retaining portions 42K provided in the box 42 and locked. This prevents the carrier tape 27 from escaping from the box 42 of the boxed roll 41 during the storage period or during the transportation period, and even prevents the entire roll 27R from falling off from the box 42.

[0051] On the other hand, when the carrier tape 27 is used after being pulled out from the boxed roll body 41, the two tape front end holding portions 42K are removed from the feed holes 27K of the carrier tape 27, and are set as follows: Figure 3 As shown in the figure, the front wall 53 is in the posture of the lower surface. By pulling out the carrier tape 27 from the rear opening 56 in the posture of the front wall 53 in the lower surface, the carrier tape 27 can be fed to the component supply unit 26. In this way, by providing the tape front end holding portion 42K in the cassette 42, the position of the front end of the carrier tape 27 in the cassette 42 is unified, so that the operation of taking out the front end of the carrier tape 27 from the cassette 42 can be easily performed. In addition, it is also easy to cope with the operation of taking out the front end of the carrier tape 27 using automated equipment such as a robot.

[0052] As the usage form of the boxed roll body 41 with respect to the component supply unit 26, for example, in addition to the following Figure 2 In addition to the form of being installed in the feeder carriage 25 as the boxed roll body 41 shown on the left side of Figure 2 The right side and Fig. 8A The boxed roll body 41 shown in FIG. 1 is mounted on the component supply unit 26 via the attachment 26A. Figure 8B As shown in FIG. 2 , the entire boxed roll body 41 is accommodated in the component supply unit 26. Alternatively, there is also a configuration as shown in FIG. Figure 8C As shown in FIG. 1 , the roll body 27R is taken out from the boxed roll body 41 , and only the roll body 27R is stored inside the component supply unit 26 .

[0053] As described above, in this embodiment, the cassette 42 of the cassette roll 41 can function as a supporting mechanism for the roll 27R when the roll 27R is placed outside the component supply unit 26 for use (the function of the reel 44 in the reel-attached roll 43 ).

[0054] Next, the carrier tape processing device 3 is described. The carrier tape processing device 3 is a device that processes the carrier tape 27 used by the component assembly device 14 to produce the boxed roll 41. The carrier tape processing device 3 has a structure that takes out the roll 27R from the reel 44 of the conventional reel-attached roll 43 and stores the roll 27R in the box 42, while collecting the reel 44.

[0055] like Fig. 9 , Fig.10 and Fig.11 As shown, the carrier tape processing apparatus 3 in the present embodiment includes a reel supply unit 61 , a reel conveyance unit 62 , a reel unloading unit 63 , a collection unit 64 , a reading unit 65 (component information acquisition unit), and a writing unit 66 .

[0056] The reel supply unit 61 has the function of supplying the attached reel reel 43. The reel supply unit 61 is as follows: Fig. 9 and Fig.10 As shown, the container is formed of a container-like member with an upper side open, for example, and holds a plurality of additional reel rolls 43 in a state of being arranged in a lateral direction.

[0057] The reel conveying section 62 has a function of holding the attached reel roll 43 supplied by the reel supply section 61 and moving it upward to the roll taking-out section 63. Fig. 9 and Fig.10 As shown in the figure, there are a gripping head 71 and a gripping head moving mechanism 72. The gripping head 71 grips the additional reel roll 43 supplied by the reel supply unit 61 with two gripping parts 71H extending downward. The gripping head moving mechanism 72 moves the gripping head 71 gripping the additional reel roll 43 in the horizontal plane direction and in the vertical direction.

[0058] The reel taking-out section 63 has a function of taking out the reel 27R from the reel 44 of the reel-attached reel 43 and storing it in the box 42. The reel taking-out section 63 includes a separation section 63A for separating the reel 27R from the reel 44 of the reel-attached reel 43, and a reel storing section 63B for storing the reel 27R separated from the reel 44 by the separation section 63A in the box 42.

[0059] Separation section 63A Fig. 9 and Fig.10 As shown in the figure, the separator 73 and the separator driving unit 74 are provided. The separator 73 is composed of a pair of movable plates 73S which are opposed to each other in the horizontal direction and extend in the vertical direction. Each movable plate 73S is provided with a U-shaped escape portion 73N ( Fig.10 ).

[0060] exist Fig. 9 and Fig.10In the embodiment, the separator driving unit 74 includes a pair of (two) arm portions 74A and an arm driving unit 74B that moves the two arm portions 74A. One end of the two arm portions 74A is respectively mounted on the two movable plates 73S, and the two arm portions 74A extend in a substantially horizontal direction. The arm driving unit 74B can change the interval between the two arm portions 74A (thereby changing the interval between the separator 73) by moving the two arm portions 74A in the horizontal direction.

[0061] exist Fig. 9 and Fig.10 In the embodiment, the roll storage section 63B includes a box holding section 63Ba and a chute section 63Bb. The roll storage section 63B has the function of holding an empty box 42 and conveying it in the horizontal direction. The chute section 63Bb has the function of guiding the roll 27R so that the rolls 27R separated from the reel 44 by the separation section 63A are stored one by one in the empty box 42 held by the box holding section 63Ba.

[0062] The box holding portion 63Ba is as follows Fig. 9 , Fig.10 and Fig.11 As shown in the figure, the cassette holding section 63Ba holds the cassettes 42 in a row with the upper openings 55 facing upward, and intermittently conveys the cassettes 42 in the horizontal direction.

[0063] The chute portion 63Bb is as follows Fig. 9 , Fig.10 and Fig.11 As shown in the figure, it is composed of a pair (two) of slide groove members 63T. The two slide groove members 63T are arranged to face each other in the direction in which the two movable plates 73S constituting the separator 73 face each other. The two slide groove members 63T are arranged below the separator 73.

[0064] exist Fig.11 In the embodiment, the two slide groove members 63T have respective upper end portions 63J that are shaped to expand toward the upper side. The interval between the upper end portions of the two slide groove members 63T is wider than the interval between the lower end portions of the two movable plates 73S constituting the separator 73. In addition, the interval between the two slide groove members 63T becomes narrower toward the lower end side ( Fig.11 ).

[0065] The chute portion 63Bb guides the roll 27R separated from the reel 44 by disassembling the reel 44 by the separation portion 63A downward, thereby storing the roll 27R in the cassette 42 located below the chute portion 63Bb. Thus, one roll 27R is stored in one cassette 42.

[0066] The recovery unit 64 has a function of recovering the reel 44 decomposed by the separation unit 63A. Fig. 9 and Fig.10 As shown, a pair of reel discharge chutes 75 and a recovery box 76 are provided.

[0067] The two reel discharge chutes 75 have a cylindrical shape with an opening that expands as it goes upward. The upper end opening 75K of each of the two reel discharge chutes 75 is located on the side of the separator 73 (on the side of each of the two movable plates 73S). The recovery box 76 is a container-shaped member with an upper opening, and is arranged below the two reel discharge chutes 75.

[0068] When the reel 44 is separated by the separation section 63A, first, the attached reel roll 43 held by the holding head 71 of the reel conveying section 62 is positioned above the separator 73 ( Fig.11 ). Then, after the interval between the upper ends of the two movable plates 73S constituting the separator 73 is made smaller than the interval between the two side plates 45 of the reel 44 constituting the additional reel reel 43 ( Fig. 12A The holding head 71 is lowered relative to the separator 73 as shown by the arrow A in the figure, so that the upper ends of the two movable plates 73S are inserted between the two side plates 45 from below ( Fig. 12A The arrow shown in B).

[0069] After the upper ends of the two movable plates 73S are inserted between the two side plates 45 from below, the arm driving unit 74B operates to gradually increase the distance between the two movable plates 73S. At this time, the distance between the two movable plates 73S is made larger than the distance between the two side plates 45 ( Fig. 12B As a result, the movable plate 73S pushes the side plate 45 outward to expand the gap between the side plate 45 and the roll body 27R.

[0070] By gradually increasing the distance between the two movable plates 73S, the gap between the side plate 45 and the roll body 27R is enlarged ( Fig. 12B ), so that the holding head 71 is further lowered relative to the separator 73 ( Fig. 12C As shown by arrow D in FIG. 1 , the two movable plates 73S are inserted into the gap between the enlarged side plate 45 and the roll body 27R. At this time, the winding core 46 enters the aforementioned escape portion 73N formed in each movable plate 73S.

[0071] After the two movable plates 73S are inserted between the side plate 45 and the roll body 27R, the arm driving unit 74B further increases the distance between the two movable plates 73S ( Fig.13 As a result, the two side plates 45 are pulled apart, and the plurality of concave portions 46K of the winding core 46 provided on one side plate 45 are separated from the plurality of convex portions 45T provided on the other side plate 45 ( Fig.13). Thus, the reel 44 is divided into two parts, a part including one side plate 45 and a part including the other side plate 45. The reel 27R separated from the reel 44 is stored in the empty box 42 located directly below the reel storage part 63B through the two slide grooves 63Bb constituting the reel storage part 63B.

[0072] On the other hand, the side plate 45 on one side of the reel 44 divided into two parts falls toward the upper end opening 75K of the reel discharge chute 75 on one side, and the side plate 45 on the other side falls toward the upper end opening 75K of the reel discharge chute 75 on the other side ( Fig.13 The two side plates 45 respectively fall through the reel discharge chute 75 and enter the recovery box 76 to be recovered.

[0073] exist Fig. 9 In the embodiment, the reading unit 65 is composed of a reader or camera that optically reads an identifier (mark) such as a barcode or a two-dimensional code printed (recorded) on the surface of the outer side of the reel 44, and is provided near the reel supply unit 61. The identifier includes component information of the component BH stored in the carrier tape 27. In the present embodiment, the reading unit 65 reads the code label 43L ( Fig. 9 and Fig.10 ) to obtain (read) the component information. Fig. 9 , Fig.10 The dotted line Br schematically shows the reading range of the reading section 65. Here, "component information" refers to information related to the component BH stored in the carrier tape 27 of the reel body 43, including at least one of the type, name, characteristics, date of manufacture, manufacturer, expiration date, number of components of the component BH and access information (URL, etc.) for accessing the type, name, characteristics, date of manufacture, manufacturer, expiration date, number of components of the component BH.

[0074] Thus, in the present embodiment, the reading unit 65 becomes a component information acquisition unit that acquires information related to the components stored in the carrier tape 27, that is, component information. It should be noted that, in the case where the reel 44 has a wireless tag storing component information, the reading unit 65 may also use a non-contact reader having the function of reading the information of the wireless tag in a non-contact manner. In addition, the reading unit 65 reads the component information from the reel 44 of the reel supply unit 61, but it may also read the component information from the reel 44 held by the holding head 71. In addition, in the present embodiment, the reading unit 65 is arranged at a position where the identifier of the reel 44 of the reel supply unit 61 can be read, but it may be any position as long as it is a position where the identifier can be read. In addition, it may also be mounted on the holding head 71 or a robot arm (not shown) so as to be movable. Moreover, the reading unit 65 may also be composed of a wireless or wired handheld scanner and controlled by the operator OP (refer to Fig.14 ) operation to read the identifier of reel 44.

[0075] The writing unit 66 writes information to the wireless tag 42M attached to the cartridge 42 held by the cartridge holding unit 63Ba by wireless communication. The information written to the wireless tag 42M by the writing unit 66 is the component information acquired (read) by the reading unit 65 and the identification information.

[0076] Here, the "identification information" is information for distinguishing a component BH stored in one reel 27R used in the component assembly system 1 from a component BH stored in another reel 27R. The identification information is composed of, for example, a serial number issued in a factory where the component assembly system 1 is installed. In the present embodiment, the identification information is generated (issued) in the management computer 6 when the reel 27R separated from the reel 44 is stored in the box 42, as described later. In addition, the identification information is also used as management information for managing the box 42. That is, the identification information is used for both the purpose of identifying the reel 27R and the purpose of identifying the box 42.

[0077] Next, the storage warehouse 4 is described. The storage warehouse 4 stores the boxed rolls 41. The boxed rolls 41 mentioned here include not only the boxed rolls 41 just manufactured by the carrier tape processing device 3, but also the boxed rolls 41 in use such as being used in the component assembly device 14 and being sent back in the middle.

[0078] exist Fig.14In the embodiment, the storage warehouse 4 has a plurality of shelf sections 82 (storage sections) in a housing 81. An entrance 83 is provided below the front surface of the housing 81, and a movable workbench 84 is provided inside the housing 81. The movable workbench 84 is extended to the outside of the housing 81 (the side close to the operator OP) and is pulled into the inside of the housing 81 (the side in the depth when viewed from the operator OP) through the entrance 83. The movable workbench 84 is extended to the side close to the operator OP when the boxed roll 41 is stored in the storage warehouse 4, and is pulled into the depth when the boxed roll 41 placed on the movable workbench 84 is stored in the housing 81.

[0079] A plurality of storage positions 82S for storing (loading) the boxed roll 41 are respectively set in advance on the plurality of shelf portions 82 provided in the storage warehouse 4. That is, in the present embodiment, each shelf portion 82 becomes a storage portion having a plurality of storage positions 82S, and the storage positions 82S store the box 42 (i.e., the boxed roll 41) containing the roll 27R.

[0080] exist Fig.14 In the embodiment, a box transfer mechanism 85 is provided in the housing 81. The box transfer mechanism 85 includes a Z-axis table 86 extending in the vertical direction (set as the Z-axis direction), a Y-axis table 87 extending in the front-rear direction (set as the Y-axis direction) when viewed from the operator OP and moving in the vertical direction via the Z-axis table 86, an X-axis table 88 extending in the lateral direction (set as the X-axis direction) when viewed from the operator OP and moving in the front-rear direction via the Y-axis table 87, and a transfer head 89 moving in the X-axis direction via the X-axis table 88.

[0081] The cassette transfer mechanism 85 moves the transfer head 89 three-dimensionally by the Z-axis table 86 moving the Y-axis table 87 along the Z-axis direction, the Y-axis table 87 moving the X-axis table 88 along the Y-axis direction, and the X-axis table 88 moving the transfer head 89 along the X-axis direction. The transfer head 89 has two fingers 89F arranged in the X-axis direction.

[0082] The transfer head 89 can move the two fingers 89F closer to or farther from each other in the X-axis direction. When the two fingers 89F are closed with the boxed roll 41 disposed between them, the boxed roll 41 is held by the two fingers 89F (i.e., by the transfer head 89).

[0083] exist Fig.14 In the embodiment, the transfer head 89 is provided with a non-contact reader 90 with its imaging field of view oriented in the depth direction when viewed from the operator OP. The non-contact reader 90 faces the wireless tag 42M provided on the box 42 of the boxed roll 41 at the position where the transfer head 89 holds the boxed roll 41.

[0084] The contactless reader 90 reads the information written in the wireless tag 42M (the component information and identification information of the component BH stored in the roll body 27R) by wireless communication while facing the wireless tag 42M. In the present embodiment, the contactless reader 90 functions as an identification information reading unit that reads the identification information written in the wireless tag 42M as a storage unit. After reading the information written in the wireless tag 42M of the boxed roll body 41, the contactless reader 90 stores the read information in the management computer 6 (described later).

[0085] A unique address is assigned to each storage position 82S set in each of the plurality of shelf sections 82. In the present embodiment, when the boxed roll 41 is stored (placed) in the storage position 82S, information (component information) of the component BH stored in the roll 27R (carrier tape 27) of the boxed roll 41 is associated (so-called linked) with the identification information of the boxed roll 41 and stored in the management computer 6. Furthermore, information (storage position information) of the component information is associated with the information of the storage position 82S and stored in the management computer 6 (described later). Thus, the management computer 6 can understand which boxed roll 41 storing which component BH is stored in which storage position 82S of the storage warehouse 4.

[0086] Fig.15 The overall control system of the component assembly system 1 is shown by a block diagram. Fig.15 As shown, the management computer 6 includes a production information management unit 91, a component monitoring unit 92, an operation instruction unit 93, and an information management unit 94. The production information management unit 91 stores production plan data in the component assembly system 1. The component monitoring unit 92 monitors the remaining number of components BH in the manufacturing line 2. When the component monitoring unit 92 predicts that the component is running out, it transmits this to the operation instruction unit 93.

[0087] The operation instruction unit 93 instructs the manufacturing line 2 and the operator OP to switch the machine model based on the production plan data stored in the production information management unit 91, and instructs the storage warehouse 4 to deliver the parts BH used in the production of the next machine model. In addition, the operation instruction unit 93 instructs the storage warehouse 4 to deliver the parts BH used in the production of the next machine model based on the information from the parts monitoring unit 92 (specifically, the delivery of the replenishment parts to the storage warehouse 4 and the parts replenishment operation to the operator OP).

[0088] The information management unit 94 includes a first information management unit 94a, a second information management unit 94b, an identification information generation unit 94c, and a storage location information generation unit 94d ( Fig.15). The first information management unit 94a manages the component information, and the second information management unit 94b manages the information (storage location information) of the storage location 82S of the component BH in the storage warehouse 4. Specifically, the first information management unit 94a stores the component information and identification information about the reel 27R separated from the reel 44 in an associated state. In addition, the second information management unit 94b stores the identification information and storage location 82S information (storage location information) about the reel 27R separated from the reel 44 in an associated state.

[0089] The identification information generating unit 94c generates (issues) identification information on the roll 27R when the carrier tape processing device 3 disassembles the reel 44 of the reel-attached roll 43 and separates the roll 27R from the reel 44. The storage position information generating unit 94d identifies the storage position 82S of the boxed roll 41 when the boxed roll 41 is stored in the storage warehouse 4 and generates the storage position information.

[0090] like Fig.15 As shown in FIG. 1 , the carrier tape processing device 3 includes a processing device control unit 3C. The processing device control unit 3C controls the reel conveying unit 62, the reel unloading unit 63, the reading unit 65, the writing unit 66, etc. included in the carrier tape processing device 3. Fig.15 As shown, the storage warehouse 4 includes a warehouse control unit 4C. The warehouse control unit 4C controls the moving table 84, the cassette transfer mechanism 85, and the non-contact reader 90 included in the storage warehouse 4.

[0091] Next, use Fig.16 The flowchart shown in FIG. 1 is used to explain the process of manufacturing the boxed roll 41 (processing the carrier tape 27) performed by the carrier tape processing device 3. First, the processing device control unit 3C of the carrier tape processing device 3 obtains the component information of the attached reel roll 43 that is the operation target among the attached reel rolls 43 supplied by the reel supply unit 61 (the component information acquisition process of step ST1). Here, the component information is acquired by reading the identifier of the code label 43L attached to the reel 44 of the attached reel roll 43 that is the operation target by the reading unit 65 ( Fig. 9 ), but other methods may be used. For example, the operator OP may input the content of the code tag 43L from an input device (not shown) connected to the processing device control unit 3C.

[0092] After obtaining the component information of the attached reel roll 43 in step ST1, the processing device control unit 3C operates the reel conveying unit 62 of the carrier tape processing device 3 to cause the gripping head 71 to grip the attached reel roll 43 as the work object. Then, after the gripping head 71 grips the attached reel roll 43, the gripping head 71 is moved ( Fig.10) and position the attached reel roll 43 above the separator 73 (positioning process of step ST2). Fig.11 ).

[0093] After positioning the attached reel reel 43 above the separator 73, the processing device control unit 3C separates the reel 44 ( Fig. 12A → Fig. 12B → Fig. 12C ), so that the reel 27R is separated from the reel 44 (separation process of step ST3). As a result, the reel 44 is divided into two parts, a part including one side plate 45 and a part including the other side plate 45, and the reel 27R is stored in the empty box 42 located directly below the reel storage part 63B through the reel storage part 63B (reel storage process of step ST4). In addition, the reel 44 divided into two parts passes through the reel discharge chute 75 and is recovered in the recovery box 76 (retainer recovery process of step ST5).

[0094] Here, the separation process of step ST3 and the roll storage process of step ST4 become a roll taking-out and storage process of taking out the roll 27R from the reel 44 and storing the roll 27R in the box 42. Here, the reel 44 is a holding body that holds the carrier tape 27 storing the components BH in the state of the roll 27R. In the roll storage process in the roll taking-out and storage process, the rolls 27R separated from the reel 44 in the separation process are stored one by one in the empty box 42. Therefore, one roll 27R can be managed in units of one box 42.

[0095] When the processing device control unit 3C separates the reel 44 in step ST3, it requests the identification information generating unit 94c of the management computer 6 to generate identification information about the reel 27R separated from the reel 44. Then, the identification information generating unit 94c, which receives the request for generating identification information from the processing device control unit 3C, generates identification information about the reel 27R taken out by separating the reel 44 (identification information generating step of step ST6).

[0096] After the identification information is generated by the identification information generating unit 94c in step ST6, the processing device control unit 3C of the carrier tape processing device 3 receives the generated identification information. Then, the component information acquired in step ST1 and the identification information generated in step ST6 are written by the writing unit 66 to the wireless tag 42M attached to the cassette 42 (the cassette 42 in which the roll 27R is stored in step ST4) (writing process in step ST7).

[0097] After writing the component information and identification information to the wireless tag 42M of the box 42, the processing device control unit 3C transmits the information written to the wireless tag 42M (component information and identification information about the roll 27R) to the management computer 6, and causes the first information management unit 94a of the management computer 6 to store the information (component information and identification information). As a result, the identification information, which is the inherent information of the roll 27R, and the component information, which is the information of the component BH stored in the roll 27R, are registered in the management computer 6 in a state of being associated with each other (component information registration process of step ST8).

[0098] After writing the information on the roll 27R into the first information management unit 94a of the management computer 6, the processing device control unit 3C ends the production of the boxed roll 41 (processing operation of the carrier tape 27) by the carrier tape processing device 3.

[0099] Next, use Fig.17 The flowchart shown in the figure will be used to explain the process of the storage operation of the boxed roll body 41. First, the warehouse control unit 4C of the storage warehouse 4 moves the movable workbench 84 from the entrance 83 provided in the housing 81 to the near side. Then, the operator OP (or a mobile robot not shown) places the boxed roll body 41 on the movable workbench 84 (placement process of step ST11). Fig.14 At this time, the boxed roll body 41 is placed on the movable workbench 84 with the upper opening 55 facing upward and the front wall 53 facing the near side (the side of the operator OP). As a result, the wireless tag 42M set in the box 42 is in a state of facing the near side ( Fig.14 ).

[0100] After the mobile workbench 84 places the boxed roll 41, the warehouse control unit 4C moves the mobile workbench 84 to pull the boxed roll 41 into the shell 81. After the boxed roll 41 is pulled into the shell 81, the warehouse control unit 4C moves the transfer head 89 to the near front side of the boxed roll 41 placed on the mobile workbench 84. Then, the two fingers 89F are operated in a closed manner to allow the transfer head 89 to hold the boxed roll 41. At this time, the non-contact reader 90 provided on the transfer head 89 is directly opposite to the wireless tag 42M of the box 42 provided on the boxed roll 41, and the non-contact reader 90 reads the identification information written into the wireless tag 42M (the identification information reading process of step ST12).

[0101] After the non-contact reader 90 reads the identification information written in the wireless tag 42M, the warehouse control unit 4C transmits the identification information read by the non-contact reader 90 to the management computer 6. After receiving the transmission of the identification information from the warehouse control unit 4C, the management computer 6 determines the storage position 82S of the boxed roll body 41 (the boxed roll body 41 whose identification information has been read by the non-contact reader 90) corresponding to the identification information in the storage position information generating unit 94d and generates the storage position information (storage position information generating process of step ST13). The storage position 82S is determined by arbitrarily selecting from the storage positions 82S that are in an idle state at that time point or selecting according to a predetermined rule.

[0102] After the storage location information generating unit 94d generates the storage location information in step ST13, the management computer 6 stores the generated storage location information and the identification information of the boxed roll body 41 corresponding to the storage location information in the second information management unit 94b in a state of being associated with each other. Thus, with respect to the boxed roll body 41 to be stored in the storage warehouse 4, the inherent information of the roll body 27R, i.e., the identification information, and the information on the storage location of the boxed roll body 41 including the roll body 27R in the storage warehouse 4 (storage location information) are registered in the management computer 6 in a state of being associated with each other (storage location information registration process of step ST14).

[0103] After the management computer 6 stores the storage information and the identification information of the boxed roll body 41 placed on the movable table 84 in the second information management unit 94b in an associated state, it operates the box transfer mechanism 85 to transfer the boxed roll body 41 placed on the movable table 84 to the storage position 82S corresponding to the storage position information for storage (storage process of step ST15). Thus, the storage operation of the boxed roll body 41 is completed.

[0104] Thus, in this embodiment, the roll 27R can be taken out from the holder such as the reel 44 and stored in the box 42, and the roll 27R can be handled as the boxed roll 41. The boxed roll 41 can be made smaller in width and more compact than the reel-attached roll 43, and the reel 44 does not remain as waste after the roll 27R (that is, the carrier tape 27) is used up, so the workability is good. In addition, the box 42 is not only inexpensive itself, but also can be reused (circulated) unlike the reel 44, so the cost can be reduced in this respect.

[0105] Furthermore, in the present embodiment, the box 42 is provided with a wireless tag 42M as a storage unit capable of storing component information, and the component information recorded on the reel 44 can be written and stored in the wireless tag 42M. Therefore, even if the roll 27R is taken out from the reel 44, the component information is not lost, and the component information can be managed for each boxed roll 41. In addition, the component information is stored in association with the identification information, which is the inherent information of the roll 27R, so the component information can be managed for each boxed roll 41.

[0106] In the above-mentioned component assembly system 1, the carrier processing device 3 (processing device control unit 3C, reel conveying unit 62, reel body unloading unit 63, reading unit 65 as a component information acquisition unit, writing unit 66), storage warehouse 4 (shelf unit 82, warehouse control unit 4C, box transfer mechanism 85, non-contact reader 90 as an identification information reading unit), information management unit 94 (first information management unit 94a, second information management unit 94b, identification information generation unit 94c and storage position information generation unit 94d) constitute a component management device 100 ( Fig.15 ).

[0107] The management operation (parts management method) of the parts BH performed using the parts management device 100 first obtains the parts information (parts information acquisition process), generates identification information (identification information generation process), writes the parts information and identification information to the wireless tag 42M provided in the box 42 (writing process), associates the written parts information with the identification information and stores them in the first information management unit 94a (parts information registration process). In addition, the processing is performed in the following steps: the identification information written in the wireless tag 42M is read by the identification information reading unit (non-contact reader 90) (identification information reading process), determines the storage location 82S and generates the storage location information (storage location information generation process), and then associates the identification information with the storage location information and stores them in the second information management unit 94b (storage location information registration process).

[0108] According to such a component management method, in addition to storing the component information about the boxed roll body 41 in association with the identification information, the identification information of the boxed roll body 41 is also stored in association with the storage location information, so that the boxed roll body 41 in the storage warehouse 4 can be stored and taken out smoothly. Therefore, according to the component management device 100 (component management method) in this embodiment, the components BH can be put in and taken out simply and efficiently.

[0109] It should be noted that the roll 27R of the boxed roll 41 handled by the component management device 100 in the present embodiment does not necessarily need to be taken out from the attached reel roll 43, and may be a roll manufactured from the beginning as the roll 27R of the carrier tape 27. For example, the roll 27R may be manufactured by measuring the length while winding a large-capacity carrier tape roll that is the basis for manufacturing the attached reel roll 43.

[0110] Fig.18 The figure shows an image of the operation of the boxed roll 41 in the component assembly system 1 in the present embodiment. As shown in the figure, the boxed roll 41 in the present embodiment is manufactured by supplying the reel roll 43 and the box 42 to the carrier processing device 3. A part of the boxed roll 41 manufactured by the carrier processing device 3 is transported to the manufacturing line 2 for use, and the other part is stored (stored) in the storage warehouse 4. The boxed roll 41 stored in the storage warehouse 4 is unloaded from the storage warehouse 4 and transported to the manufacturing line 2 for use. In addition, the box 42 generated due to the exhaustion of the carrier tape 27 of the boxed roll 41 in the manufacturing line 2 is recovered and supplied to the carrier processing device 3, and reused in the manufacture of a new boxed roll 41. In addition, a part of the boxed roll 41 that is transported to the manufacturing line 2 and in a state where the carrier tape 27 has not been exhausted is sent back to the storage warehouse 4 for storage (stored).

[0111] As described above, in the component management device 100 (component management method) of the present embodiment, the roll 27R is taken out from the holding body such as the reel 44 and stored in the box 42, and the roll 27R can be handled as the boxed roll 41. The boxed roll 41 can be made smaller in width and more compact than the reel-attached roll 43, and the reel 44 does not remain as waste after the roll 27R (that is, the carrier tape 27) is used up, so the workability is good. In addition, the box 42 is not only cheap in itself, but also can be reused (circulated) unlike the reel 44, so the cost can be reduced in this respect.

[0112] Furthermore, in the present embodiment, the identification information of the boxed roll 41 is associated with the storage position information and stored, so that the boxed roll 41 in the storage warehouse 4 can be stored and taken out smoothly. Therefore, according to the component management device 100 (component management method) in the present embodiment, the components BH can be put in and taken out simply and efficiently.

[0113] The embodiments of the present disclosure have been described so far, but the present disclosure is not limited to the above-mentioned embodiments, and various modifications are possible. For example, in the above-mentioned embodiments, the reel 44 with the reel reel body 43 is divided into two parts, but this is an example, and it can also be divided into three or more parts. Even in this case, the multiple parts generated by the decomposition can be made to fall into the recovery box 76 through the reel discharge chute 75, and the decomposed reel 44 can be reliably recovered.

[0114] The structure of the disassembly mechanism of the reel 44 and the disassembly method shown in the above embodiment are examples, and the reel 27R may be disassembled by other methods to be taken out from the reel 44. Furthermore, if the reel 44 can be taken out without disassembling the reel 44 (for example, the reel 44 has a single side plate 45, and the core 46 extends from the single side plate 45 in a cantilevered state, and the reel 27R can be separated from the reel 44 as long as the reel 27R can be taken out from the core 46), the reel 44 does not necessarily need to be disassembled. Furthermore, the specific structure of the reel taking-out portion 63 shown in the above embodiment is only an example, and the structure is free as long as the reel 27R can be taken out from the holding body such as the reel 44 and stored in the box 42. The reel 44 holds the carrier tape 27 storing the component BH in the state of the reel 27R.
