Disclosure of Invention

Summary of the invention

Problems to be solved by the invention

However, the component-housing storage described in patent document 2 has room for improvement in terms of shortening the time required for the component housing to be taken out.

In the present specification, a technology is disclosed that can shorten the time required for the shipment of any type of component housing.

Means for solving the problems

(1) According to one aspect of the present invention, a component storage is configured to store a component storage body that stores components to be mounted on a substrate, the component storage including: a plurality of storage locations for storing one of the component containers; an in-out/in-out place for placing the component housing to be in-out/in; a moving unit for moving the component storage unit in the component storage; a receiving unit that receives an instruction to deliver the component; and a control unit configured to secure, as a priority storage location, a number of storage locations equal to or greater than the number of types of the components stored in the component storage in order of a short movement time to the in-out storage location, the control unit performing: a first moving process of moving at least one component housing body to the preferential storage place by the moving unit for each type of the components stored in the component storage before receiving an instruction to discharge the components; and a second movement process of, when receiving an instruction to deliver a certain type of component, moving the component housing body housing the component of the type from the priority storage location to the delivery/delivery storage location by the movement unit.

In the case of the component-container storage described in patent document 2, when the component container stored in the storage rack far from the doorway (in other words, the storage rack having a long movement time to the doorway) is taken out of the storage rack, the movement time from the storage rack to the doorway is long, and therefore, it takes time from the acquisition of the preparation instruction to the transfer of the component container to the doorway.

In contrast, the component storage according to the present invention secures, as the priority storage, the storage having the number equal to or greater than the number of types of components stored in the component storage, in order of the movement time to the entry/exit storage from the storage. Before receiving the instruction for the component to be delivered, the component storage moves at least one component storage body to a priority storage location for each type of component stored in the component storage. When the component storage receives an instruction to deliver a component of a certain type, the component storage moves the component storage body containing the component of the certain type from the priority storage location to the delivery and storage location. The preferential storage location has a shorter movement time to the in-out storage location than a storage location other than the preferential storage location (hereinafter referred to as a non-preferential storage location), and therefore, the component storage can be moved to the in-out storage location in a short time regardless of which type of the component storage is instructed to be in-out. Therefore, according to the component storage of the present invention, the time required for the shipment can be reduced regardless of the type of component container, as compared with the component container storage described in patent document 2.

(2) According to an aspect of the present invention, two storage racks may be arranged in parallel, each of the two storage racks may have a plurality of storage locations, the access storage location may be provided in one of the storage racks, and the priority storage location may be secured in the other storage rack.

According to the component storage described above, when the two storage racks are arranged in parallel, the time required for the delivery of the component storage bodies can be shortened by ensuring the priority storage location in the other storage rack, and by ensuring the priority storage location in the other storage rack, the time required for the delivery of the component storage bodies can be shortened regardless of the type of the component storage bodies.

(3) According to one aspect of the present invention, a component storage is configured to store a component storage body that stores components to be mounted on a substrate, the component storage including: two pipe-protecting frames arranged in parallel; a plurality of storage places provided in each of the storage racks, each of which stores one of the component storage bodies; an in-out/in-out place provided on one of the storage racks, and on which the component storage body to be in-out/in-out is placed; a moving unit for moving the component storage unit in the component storage; a receiving unit that receives an instruction to deliver the component; and a control unit configured to ensure, at the one storage rack, a predetermined number of storage locations as storage waiting locations in order of a short moving time to the storage locations, and to ensure, at the other storage rack, a priority storage location as storage locations in order of a short moving time to the storage locations, a number of storage locations equal to or greater than the number of types of components stored in the component storage, the control unit configured to execute: a first moving process of moving at least one component housing body to the preferential storage place by the moving unit for each type of the components stored in the component storage before receiving an instruction to discharge the components; a third movement process of moving, by the moving section, the component housing bodies stored in the component housing bodies in the priority storage location, in which the order of the component housing bodies to be delivered is relatively early, to the delivery waiting location; and a fourth movement process of, when receiving an instruction to deliver a certain type of component, moving the component housing body housing the component of the certain type from the delivery waiting place to the delivery warehouse place by the movement unit.

According to the component storage described above, the component storage having a relatively early order of the components to be discharged is moved from the priority storage location to the discharge waiting location before the components to be discharged are discharged, so that the time required for moving the components to be discharged to the in-out storage location can be shortened when the component storage is instructed to discharge the components. Therefore, according to the above-described component storage, the time required for the shipment can be shortened regardless of the type of component storage.

(4) According to an aspect of the present invention, the control unit may execute a process of newly securing the priority storage location when the component storage body storing the component of the type not stored in the component storage is stocked.

According to the component storage, even if a new component storage is stored, the component storage of the new storage type can be stored in the priority storage location.

(5) According to an aspect of the present invention, the first movement process may be performed by setting a priority of the shipment of each component container, and the control unit may move the component container having the highest priority to the priority storage location for each type of component container.

According to the component storage described above, the components can be first-out from the component storage having a high priority for the component storage for each type of component.

(6) According to an aspect of the present invention, the component storage may include a dehumidifier that dehumidifies an interior of the component storage, and the preferential storage may be secured in order from a near side to a far side with respect to the storage, with the exception of the component storage body that stores the components of the type that are unsuitable for contact with air having a high humidity.

The dry air dehumidified by the dehumidifier is blown out in the vicinity of the outlet of the dehumidifier. According to the above-described component storage, since the priority storage locations are ensured in the order of the distance from the outlet of the dehumidifier with respect to the component storage body in which the components of the type unsuitable for contact with the air having high humidity are stored, the possibility of contact between the components of the type unsuitable for contact with the air having high humidity and the air having high humidity can be reduced.

The invention disclosed in the present specification can be implemented in various forms such as an apparatus, a method, a computer program for realizing the functions of the apparatus or the method, and a recording medium on which the computer program is recorded.

Detailed Description

< embodiment 1>

Embodiment 1 will be described with reference to fig. 1 to 12. In the following description, the same constituent members may be omitted from the drawings except for some portions.

(1) Substrate production equipment

Referring to fig. 1, a substrate production apparatus 1 for mounting components to a substrate is described. The substrate production apparatus 1 includes a production line 2 for mounting components on a substrate, a component tower 3 (an example of a component storage), and a management computer 4, which are communicably connected via a communication network 5 such as LAN (Local Area Network).

The production line 2 includes a loader 10, a screen printer 11, a printing inspection machine 12, a dispenser 13, a plurality of surface mounting machines 14, a post-mounting appearance inspection machine 15, a reflow apparatus 16, a post-curing appearance inspection machine 17, and an unloader 18, which are connected in series via a plurality of conveyors 19.

The surface mounting machine 14 includes a mounting portion for mounting components on a substrate and a component supply device for supplying components to the mounting portion. A plurality of reels 26 (see fig. 3) around which the component tape 25 (see fig. 2) is wound are provided in the component supply device. The reel 26 is an example of a component housing. The component supply device includes an electric type feeding device for feeding out the component tape 25, and supplies the components to the mounting portion by feeding out the component tape 25 by the feeding device.

The management computer 4 is a computer in which various information about the substrate production apparatus 1 is registered. The various information includes production plan information of the substrate, component remaining number information indicating the number of components remaining on each reel 26 mounted on the component supply device, various information about the reels 26, and the like.

The reel 26 includes various information such as a reel ID for uniquely identifying the reel 26, information indicating the type of the component housed in the reel 26, an unsealing date and time, a number of days of humid air, a number of days of oxidation, a guarantee period, and the like.

The unsealing date and time is the date and time when the plastic bag of the housing reel 26 is unsealed. The reel 26 is housed in a plastic bag and is supplied from the component manufacturer. The plastic bag is opened when the reel 26 is used, and the operator registers the opening date and time in the management computer 4.

The number of days of humid air is the number of days that the components housed in the reel 26 cannot be used due to the humid air. When the number of days of humid air passes from the date and time of opening, the component housed in the reel 26 cannot be used.

The number of days of oxidation is the number of days that the element accommodated in the reel 26 cannot be used due to oxidation. When the number of days of oxidation has elapsed from the date and time of opening, the element housed in the reel 26 becomes unusable.

The guarantee period is a period during which the component manufacturer that provides the spool 26 guarantees the quality of the component.

The above information is an example of information related to the spool 26. The information relating to the spool 26 is not limited thereto.

(2) Component tape and reel

As shown in fig. 2, the component tape 25 is a tape that accommodates a plurality of components E. The component tape 25 has: the carrier tape 25B having a plurality of accommodating recesses 25A at equal intervals in the longitudinal direction; the element E is accommodated in each accommodation recess 25A; and a release tape 25C attached to the upper surface of the carrier tape 25B. At one side in the width direction of the component tape 25, conveyance holes 25D are provided at equal intervals in the longitudinal direction, and the conveyance holes 25D are inserted with teeth of a sprocket provided in a feeder of the component feeder. The components E are of a plurality of types, and the same type of components E are accommodated in one component tape 25.

As shown in fig. 3, the component tape 25 is wound around a reel 26. The reel 26 is marked with a bar code 27 indicating the reel ID of the reel 26. The reel ID may be represented by a two-dimensional code instead of the barcode 27.

When the number of components remaining in the component tape 25 in the current use is reduced, the operator of the surface mounter 14 removes the reel 26 around which the component tape 25 in the current use is wound and installs a new reel 26, and connects the front end portion of the new component tape 25 to the rear end portion of the component tape 25 in the current use. The work of joining the front end portion of the new component tape 25 to the rear end portion of the component tape 25 in current use is generally called splicing. The feeding device is capable of mounting two component tapes 25, and has an automatic loading function of automatically feeding one component tape 25 when the other component tape 25 becomes component-depleted.

In the following description, the component E stored in the component tape 25 wound around the reel 26 will be referred to simply as "component E stored in the reel 26".

(3) Part tower

Referring to fig. 4, the external appearance of the component tower 3 is described. The component tower 3 is a storage for storing the reels 26. The component tower 3 has a box-shaped main body 30 having a transverse direction (W) of 2600cm, a depth (L) of 1350cm, and a height (H) of 2500 cm. A rectangular opening (not shown) is formed in a front surface of the storage main body 30 at a position on a front side of an access rack 33 (see fig. 5) to be described later. An opening/closing door 31 is rotatably connected to the storage main body 30, and the opening/closing door 31 opens and closes the opening. An operation unit 41 is provided on the right side of the opening/closing door 31 on the front surface of the library main body 30.

The inside of the component tower 3 will be described with reference to fig. 5 and 6. The component tower 3 includes: a holding rack 32 for holding the reels 26; an in-out-in-storage rack 33 on which the reels 26 to be in-out-of-storage are mounted; a moving unit 34 (see fig. 6) that moves the reel 26 stored in the storage rack 32 or the reel 26 placed in the entry/exit rack 33; and a scanner 42 (see fig. 7).

As shown in fig. 5 and 6, the storage rack 32 is composed of a front storage rack 32A (one example of a storage rack) and a rear storage rack 32B (another example of a storage rack). The rear storage rack 32B has a longitudinal direction 34 and 7 lateral direction rows, and stores one reel 26 in each row. In the following description, a place where one spool 26 is stored will be referred to as a storage place 38. The front storage rack 32A has the same overall structure as the rear storage rack 32B, but is provided with a warehouse-in/warehouse-out rack 33 in the central portion. The in-out and in-in rack 33 has a longitudinal direction of 14 segments and a transverse direction of 2 rows, and one reel 26 is placed on each segment. In the following description, a place where one reel 26 is placed in the in-out rack 33 will be referred to as an in-out place 39.

The moving unit 34 will be described with reference to fig. 6. The moving unit 34 is a mechanism for moving the spool 26 between the warehouse-in/out site 39 and the storage site 38. The moving unit 34 moves the spool 26 between the storage locations 38 as well, as will be described in detail below. The moving section 34 includes a moving head 34A that holds the spool 26, and a head moving section 34B that moves the moving head 34A in two dimensions up and down and left and right.

The moving head 34A is configured to hold the spool 26 by sandwiching it from above and below, and includes a head body 35, a holding portion 36 for holding the spool 26, a not-shown forward and backward moving mechanism, and a not-shown lifting mechanism. The clamp 36 is supported by the head body 35 so as to be movable in the front-rear direction. The clamp 36 includes: two upper extension portions 37 extending forward from the upper side of the spool 26; and a lower extension portion, although not seen in fig. 6, extending forward from the lower side of the spool 26. A forward/backward movement mechanism, not shown, is provided in the head main body 35, and moves the clamp 36 forward/backward. A lifting mechanism, not shown, is provided in the holding portion 36 to lift and lower the upper extension portion 37.

The head moving unit 34B includes a moving mechanism for moving the moving head 34A up and down and right and left, and a rotating mechanism for rotating the moving head 34A about a plumb line by 180 ℃.

When the reel 26 stored in the storage location 38 is taken out by the moving head 34A, the component tower 3 moves the moving head 34A to the target storage location 38 by the head moving unit 34B. The component tower 3 moves the holding portion 36 forward by the forward/backward movement mechanism while the upper extension portion 37 is lifted. When the holding portion 36 is moved to the front side, the upper extension 37 is located at the upper side of the spool 26 and the lower extension is located below the spool 26.

In this state, the component tower 3 lowers the upper extension 37 by the elevating mechanism. When the upper extension 37 is lowered, the spool 26 is sandwiched by the upper extension 37 and the lower extension. In this state, the component tower 3 moves the clamping portion 36 to the rear side by the forward/backward movement mechanism. Thereby removing the spool 26. The spool 26 is stored in the storage location 38 in the opposite manner.

When the reel 26 stored in the rear storage rack 32B is taken out, the component tower 3 rotates the moving head 34A about the plumb line by 180 ℃. The operation after rotating the moving head 34A by 180 ℃ is the same, and therefore, the description thereof is omitted.

The scanner 42 (see fig. 7) is provided to the moving head 34A. The bar code 27 marked on the spool 26 is read by the scanner 42 while the spool 26 is held by the moving head 34A. The scanner 42 may be provided at a predetermined position in the parts tower 3. In this case, the spool 26 held by the moving head 34A moves to the reading position of the scanner 42 to read the barcode 27.

(4) Electrical structure of component tower

Referring to fig. 7, the electrical structure of the component tower 3 will be described. The component tower 3 includes a control unit 40, a moving head 34A, a head moving unit 34B, an operation unit 41, and a scanner 42.

The control unit 40 includes a microcomputer 40A, a memory unit 40B, and a communication unit 40C (an example of a receiving unit), which are configured to have a CPU, a RAM, and the like as a single chip. The storage unit 40B stores various control programs, a management table for managing the reels 26 stored in the component tower 3, and the like. The microcomputer 40A executes a control program stored in the storage unit 40B to control each unit of the component tower 3. The communication unit 40C is a communication circuit for the microcomputer 40A to communicate with other devices via the communication network 5.

The control unit 40 may include ASIC (Application Specific Integrated Circuit), FPGA (Field Programmable Gate Array), and the like instead of the microcomputer 40A.

The operation unit 41 includes a display device such as a liquid crystal display, and an input device such as a keyboard, a mouse, and a touch panel. The operator can instruct the reel 26 to be put in and taken out by operating the operating unit 41.

(5) Management table

The aforementioned management table will be described with reference to fig. 8. When the operator puts the reel 26 in storage in the component tower 3, the reel ID is read by the scanner 42. The control unit 40 acquires various information on the reel 26 indicated by the read reel ID from the management computer 4, and registers the information in the management table in association with the reel ID.

As shown in fig. 8, the management table of embodiment 1 includes data items such as a reel ID field, a storage place field, an element type field, a warehouse date and time field, an unsealing date and time field, a humid air day field, a days of oxidation field, and a guarantee period field. The storage location column is a data item in which information indicating the storage location 38 of the storage reel 26 is registered. At the time point when the reel ID is read, the storage space is also empty, and when the reel 26 moves to the storage space 38, information indicating the storage space 38 is registered in the storage space. The component type field is a data item in which information indicating the type of the component is registered. The date and time column is a data item in which the date and time of the reel 26 being put in the component tower 3 is registered. The unsealing date and time column, the humid air day column, the oxidation day column, and the guarantee period column are data items in which the unsealing date and time, the humid air day, the oxidation day, and the guarantee period are registered, respectively.

When the reels 26 stored in the component tower 3 are discharged, the control unit 40 deletes the information of the discharged reels 26 from the management table.

(6) Priority of spool out of stock

The number of days of humid air, the number of days of oxidation, the warranty period, and the like are set on the spool 26 as described above. In the present embodiment, the earliest deadline among the deadline for the unavailability of the element E by the humid air (the time elapsed from the date and time of opening and the number of days of humid air), the deadline for the unavailability of the element E by oxidation (the time elapsed from the date and time of opening and the number of days of oxidation and the guaranteed deadline) is set as the consuming deadline of the spool 26, and the higher the priority of the delivery is for the spool 26 whose consuming deadline is earlier.

(7) Priority storage location

The preferred storage location 80 secured in the rear storage rack 32B will be described with reference to fig. 9. In fig. 9, a box indicated by a thick line 50 indicates the position of the warehouse-in/out place 39 provided in the front storage rack 32A. In embodiment 1, the time required for moving the priority storage space 80 from the priority storage space 80 to the in-out warehouse 39 is shorter than the time required for moving the priority storage space 80 from the front storage space 32A to the rear storage space 32B. Therefore, in embodiment 1, the priority storage location 80 is secured in the rear storage rack 32B. The movement time may be determined by the distance to the warehouse-in/out site 39, and may not be determined by the distance alone. This is because the movement time of the moving head 34A varies even if the distance to the warehouse 39 is the same.

Specifically, in the rear storage rack 32B, the storage locations 38 are provided with the same number of storage locations 38 as the number of types of reels 26 stored in the component tower 3, as the priority storage locations 80, in order of the moving time to the warehouse-in/warehouse-out locations 39 from short to long. For example, the number of types of reels 26 stored in the component tower 3 is 8. In this case, as shown in fig. 9, 8 storage locations 38 (storage locations 38 surrounded by a rectangular frame indicated by a dotted line 51, in other words, storage locations 38 marked with hatching) having a short movement time of the entry/exit location 39 are secured as priority storage locations 80 (an example of securing processing). For simplicity, the storage locations 38 that are not the preferred storage locations 80 will be referred to as non-preferred storage locations in the following description.

If there are a plurality of storage locations 38 having the same movement time to the warehouse 39, any one storage location 38 among the plurality of storage locations 38 may be "a storage location 38" having a short movement time to the warehouse 39. Specifically, in fig. 9, the storage locations 38 in the frame indicated by the thick line 50 have the same movement time to the warehouse-in/warehouse-out location 39, and all have the shortest movement time to the storage locations 38 in/warehouse-out location 39. In this case, any one of the storage locations 38 may be secured as the priority storage location 80. The preferential storage site 80 may not be continuous.

In the present embodiment, each of the priority storage locations 80 does not correspond to a specific type of spool 26. Therefore, the spool 26 can be stored in any one of the preferential storage places 80.

When the new reel 26 is put in the component tower 3, the priority storage location 80 is dynamically secured. For example, in the example shown in fig. 9, when a new type of reel 26 is put in storage, the number of types of reels 26 stored in the component tower 3 is 9. In this case, as shown in fig. 10, one storage location 38 among the storage locations 38 having a short movement time of the entry/exit location 39 is newly secured as a ninth priority storage location 80.

When another type of spool 26 has been stored in the newly secured priority storage location 80, the spool 26 is moved to a non-priority storage location, and the newly stored spool 26 is stored in the storage location 38 (newly secured priority storage location 80).

(8) Movement of reels

Before receiving the instruction to store the reels 26, the control unit 40 moves at least one of the reels 26 to the priority storage location 80 for each type of the components E stored in the component tower 3 (an example of the first movement process). When receiving an instruction to deliver one type of reels 26, the control unit 40 moves the reels 26 storing the type of components E from the priority storage 80 to the warehouse 39 (an example of the second movement process) by the movement unit 34. Hereinafter, description will be made specifically.

(8-1) first movement processing

The first movement process is described with reference to fig. 11. As described above, when the operator puts the reel 26 in storage in the parts tower 3, the reel ID is read by the scanner 42. When the reel ID is read by the scanner 42, the present process is started.

Here, as described above, the priority storage location 80 is newly secured when a new type of spool 26 is put in storage, but in the following description, a case in which the same type of spool 26 as the spool 26 that has been stored is put in storage will be described as an example. Therefore, the step of storing the new reel 26 in the warehouse to newly secure the priority storage location 80 is omitted.

In S101, the control unit 40 acquires information on the reel 26 indicated by the read reel ID from the management computer 4 and registers the information in the management table.

In S102, the control unit 40 reads out information on the reel 26 of the same type as the reel 26 to be put in storage from the management table.

In S103, the control unit 40 determines whether or not the spool 26 of the same type as the spool 26 to be stored is stored in the priority storage location 80, and the process proceeds to S104 when stored, and proceeds to S107 when not stored.

Here, when the same kind of reels 26 as the reels 26 to be stocked are not stored in the priority storage 80, the same kind of reels 26 as the reels 26 to be stocked are not stored in the component tower 3, and therefore, a new kind of reels 26 are stocked in the component tower 3. That is, the types of reels 26 stored in the component tower 3 are increased. Therefore, the control unit 40 newly secures the priority storage location 80.

In S104, the control unit 40 compares the priority of the reel 26 stored in the warehouse with the priority of the same type of reel 26 stored in the component tower 3. The control unit 40 proceeds to S105 when the priority of the spool 26 to be put in is high, and proceeds to S108 when it is low.

In S105, the control unit 40 temporarily moves the reel 26 to be stored to a non-preferential storage location.

In S106, the control unit 40 moves the reels 26 of the same type in the preferential storage place 80 to the non-preferential storage place.

In S107, the control unit 40 moves the spool 26 to be stored to the priority storage location 80.

In S108, the control unit 40 stores the reel 26 stored in the storage location in a non-priority storage location.

(8-2) second movement processing

The second movement process is described with reference to fig. 12. When the remaining number of components of one reel 26 is equal to or less than a predetermined number, the surface mounter 14 instructs the controller 40 of the component tower 3 to send out the same type of components E as the type of components E stored in the reel 26. When the component tower 3 is instructed to be taken out of the reel 26 from the surface mounting machine 14, the second moving process is started. The instruction to leave the warehouse may be made by an operator operating the operation unit 41.

In S201, the control unit 40 moves the reel 26 containing the component E of the type indicated in the warehouse from the priority storage place 80 to the warehouse-in/warehouse-out place 39.

In S202, the control unit 40 determines whether or not the same type of element E is stored in a non-priority storage location, and proceeds to S203 when stored, and proceeds to S204 when not stored.

In S203, the control unit 40 moves the spool 26 stored in the non-priority storage location and the spool 26 of the same type as the spool 26 instructed to be discharged to the priority storage location 80. Specifically, the control unit 40 moves the spool 26 to the priority storage 80 when the number of spools 26 of the same type stored in the non-priority storage is only one, and moves the spool 26 having the highest priority among the plurality of spools 26 to the priority storage 80 when there are a plurality of spools 26 of the same type.

In S204, the control unit 40 excludes the storage site 38 with the longest movement time to the in-out warehouse 39 from the priority storage sites 80, among the storage sites 38 secured as the priority storage sites 80. When the spool 26 is stored in the priority storage 80 having the longest moving time to the warehouse 39, the control unit 40 moves the spool 26 to another empty priority storage 80 (for example, the priority storage 80 storing the spool 26 to be discharged), and excludes the priority storage 80 storing the spool 26 from the priority storage 80.

(10) Effects of the embodiments

According to the component tower 3, before receiving an instruction to store the reels 26, at least one of the reels 26 is moved to the priority storage location 80 for each type of the components E stored in the component tower 3. The priority storage location 80 has a shorter movement time to the in-out warehouse location 39 than the non-priority storage location, and therefore, the reels 26 can be moved to the in-out warehouse location 39 in a short time regardless of which kind of reels 26 are instructed to be out of the warehouse. Therefore, according to the component tower 3, the time required for the spool 26 to be taken out of the warehouse can be shortened regardless of the type of the spool 26.

According to the component tower 3, the two storage racks 32A and 32B are arranged in parallel, and the priority storage place 80 is secured to the rear storage rack 32B, so that the time required for the spool 26 to be taken out can be shortened. Therefore, the component tower 3 can ensure the preferential storage place 80 in the rear storage rack 32B. Therefore, the time required for the shipment can be shortened regardless of the kind of the reel 26.

According to the component tower 3, when the reels 26 storing the components E of the type not stored in the component tower 3 are stocked, the priority storage 80 is newly secured, and therefore even if the reels 26 of the new type are stocked, the reels 26 of the new type can be stored in the priority storage 80.

The priority of the shipment of the reels 26 is set according to the component tower 3, and the reels 26 having the highest priority are moved to the priority storage place 80 for each type of the reels 26, so that the reels 26 having the highest priority can be first stocked for each type of the components E.

< embodiment 2>

Embodiment 2 will be described with reference to fig. 13.

(1) Waiting place for warehouse out

A delivery waiting place secured in the front storage rack 32A will be described with reference to fig. 13. In embodiment 2, as in embodiment 1, a priority storage location 80 is secured in the rear storage rack 32B. In embodiment 2, the storage locations 38 around the warehouse-in/out location 39 among the plurality of storage locations 38 of the front storage rack 32A are set as the warehouse-out waiting locations 81. Specifically, in the front storage rack 32A, a predetermined number (52 in the example shown in fig. 13) of storage locations 38 (storage locations 38 surrounded by rectangular frames indicated by thick lines 61, in other words, storage locations 38 marked with hatching) are set as the warehouse-out waiting locations 81 for the storage locations 38 in order of the moving time to the warehouse-in/warehouse-out locations 39.

In embodiment 2, the movement time from the warehouse-out waiting place 81 to the warehouse-in/out place 39 is shorter than the movement time from the priority storage place 80 to the warehouse-out place 39 secured by the storage rack 32B on the rear side. The warehouse-out waiting space 81 is closer to the warehouse-in and warehouse-out space 39 than the other storage space 38, and therefore, when the warehouse-out is instructed, the spool 26 can be moved to the warehouse-in and warehouse-out space 39 in a shorter time than the other storage space 38.

(2) Movement of reels

As in embodiment 1, before receiving the instruction to deliver the component E, the control unit 40 moves at least one spool 26 to the priority storage location 80 for each type of component E stored in the component tower 3 (an example of the first movement process).

Next, the control section 40 receives the component remaining number information of each reel 26 from the surface mounter 14 via the communication network 5. The component remaining number information includes the component remaining number of each reel 26 provided to the component supply device. The control unit 40 receives production plan information of the substrate from the surface mounter 14, for example, when starting production of the substrate. The production plan information of the substrates includes the types of the substrates to be produced, the order in which the substrates of the respective types are produced, the number of the substrates of the respective types to be produced, the types of the elements E to be mounted on the substrates of the respective types, the number of the respective types, and the like. The control unit 40 may receive these pieces of information from the management computer 4.

The control unit 40 determines the order in which the reels 26 stored in the component tower 3 are to be discharged based on the received production schedule information, component remaining amount information, and the like. The control unit 40 causes the reels 26 stored in the priority storage 80 to be moved from the priority storage 80 to the waiting area 81 for delivery (an example of the third movement process) in advance before the reels 26 are instructed to be delivered.

When receiving an instruction to deliver one type of reels 26, the control unit 40 moves the reels 26 stored in the delivery waiting place 81 to the delivery/storage place 39 by the moving unit 34 (an example of the fourth movement process).

The third movement process and the fourth movement process are specifically described below.

(2-1) third movement Process

For example, when starting production of the substrates, the control unit 40 determines that a plurality of components E stored in the reels 26 are used for each substrate for each reel 26 provided to the component supply device. The control unit 40 divides the number of components remaining in each reel 26 by the number of components E used for each substrate for each reel 26, and calculates the number of substrates that can be produced remaining for each reel 26.

Since the reels 26 having a smaller number of substrates to be produced need to be replaced first, the reels 26 having the same types of components E as those contained in the reels 26 having a smaller number of substrates to be produced need to be stocked first. Accordingly, the control unit 40 determines, for each reel 26 provided to the component supply apparatus, the order from the number of substrates that can be produced remaining being reduced to the number of substrates that can be produced remaining being increased, and determines the order in which the components E of each type are discharged from the magazine according to the type of the components E of each reel 26. The control unit 40 determines the order in which the reels 26 are discharged from the order in which the various types of components E are discharged.

For example, the type of the component E stored in the reel 26 having the smallest number of substrates that can be produced among the reels 26 mounted to the component supply apparatus is a, the type of the component E stored in the second smallest reel 26 is B, and the type of the component E stored in the third smallest reel 26 is C. In this case, the control unit 40 determines that the reels 26, and 26 of the components E, a, B, and C are sequentially discharged.

The control unit 40 moves the reel 26 to be delivered in the earlier order (in other words, the reel 26 containing the component E to be delivered in the earlier order) from the priority storage place 80 to the delivery waiting place 81. Hereinafter, the description will be made specifically. For easy understanding, in the following description, the warehouse-out waiting space 81 is initially empty.

The control unit 40 controls the moving heads 34A and 34B to move the reels 26 stored in the priority storage 80 to the shipment waiting location 81 in an order from the earlier order to the later order.

When the shipment waiting space 81 is full, the control unit 40 determines whether or not the reels 26 of the same type as the reels 26 are stored in the component tower 3 for each of the reels 26 moving from the priority storage space 80 to the shipment waiting space 81, and moves the reels 26 of the same type from one non-priority storage space to the priority storage space 80 when stored in the component tower 3. When the same kind of reels 26 as the reels 26 moving from the priority storage 80 to the warehouse-out waiting 81 are not stored in the component tower 3, the storage 38 having the longest moving time to the warehouse-in/out 39 among the storage 38 set as the priority storage 80 is excluded from the priority storage 80. When the spool 26 is stored in the storage location 38 having the longest movement time, the spool 26 stored in the storage location 38 having the longest movement time is moved to the empty priority storage location 80.

(2-2) fourth movement Process

When the remaining number of components of one reel 26 is equal to or less than a predetermined number, the surface mounter 14 instructs the controller 40 of the component tower 3 to send out the same type of components E as the type of components E stored in the reel 26. When the control unit 40 instructs the shipment, the reel 26 containing the instructed type of component E is moved from the shipment waiting location 81 to the shipment/shipment location 39.

When the spool 26 stored in the shipment waiting space 81 is moved to the in-out warehouse 39 and the shipment waiting space 81 is left empty, the control unit 40 sequentially moves from the spool 26 stored in the spool 26 of the priority storage space 80 to the shipment waiting space 81 in the order of shipment. When the same kind of reels 26 as the reels 26 moved from the priority storage 80 to the shipment waiting 81 are stored in the component tower 3, the control unit 40 moves the same kind of reels 26 to one priority storage 80.

(3) Effects of the embodiments

According to the component tower 3 of embodiment 2, the reels 26 whose order of delivery is relatively early are moved from the priority storage place 80 to the delivery waiting place 81 before delivery of the reels 26 is instructed. Therefore, compared with the case where the spool 26 is not moved from the priority storage place 80 to the warehouse-out waiting place 81, the time required for moving the spool 26 to be warehouse-out to the warehouse-in/warehouse-out place 39 can be shortened when the instruction to warehouse-out the spool 26 is received. Therefore, according to the component tower 3, the time required for the spool 26 to be taken out of the warehouse can be shortened.

< embodiment 3>

Embodiment 3 will be described with reference to fig. 14.

As shown in fig. 14, the component tower 3 of embodiment 3 includes two dehumidifiers 71 on the rear side. In the component tower 3, a suction port and a discharge port, not shown, are provided in the vicinity of each dehumidifier 71, and the suction port and the discharge port are connected to the dehumidifier 71, respectively. The air in the component tower 3 is sucked into the dehumidifier 71 through the air inlet, dehumidified by the dehumidifier 71, and discharged into the component tower 3 through the discharge port.

Since the vicinity of the warehouse-in/warehouse-out site 39 is easily contacted with the outside air, a device E of a type unsuitable for contact with air having a high humidity (hereinafter referred to as a device E requiring humidity control) is unsuitable for storage in the vicinity of the warehouse-in/warehouse-out site 39. Therefore, in embodiment 3, the priority storage location 80 is secured in the vicinity of the ejection port, except for the reel 26 around which the component tape 25 containing the component E of the type requiring humidity management is wound. Specifically, the priority storage locations 80 are ensured to be the number of types of reels 26 requiring humidity management, in order from the storage location 38 closest to the ejection port.

In embodiment 3, for example, information indicating whether humidity management is necessary is included in the information of the reel 26 acquired from the management computer 4. The control unit 40 determines whether or not the spool 26 to be stocked is the spool 26 of the type requiring humidity management based on the information acquired from the management computer 4, and stores the spool 26 of the type requiring humidity management in the priority storage location 80 secured in the vicinity of the ejection port.

According to the component tower 3 of embodiment 3, the storage space 38 in the vicinity of the outlet of the dehumidifier 71 is ensured as the priority storage space 80 with respect to the reel 26 in which the component E of the type unsuitable for contact with the air having high humidity is accommodated, and therefore, the possibility of contact between the component E of the type unsuitable for contact with the air having high humidity and the air having high humidity can be reduced.

In this case, when a plurality of reels 26 of the same type are stored in the component tower 3, any one of the reels 26 of the same type may be stored in the priority storage 80. Alternatively, the spool 26 may be a first-in-first-out spool that goes out of the warehouse first-in first-out spool.

(6) In embodiment 2, the case where the control unit 40 of the component tower 3 determines the order of the reels 26 to be discharged based on the production schedule information, the component remaining amount information, and the like will be described as an example. In contrast, the surface mounter 14 or the external management computer 4 may determine the order of the reels 26 to be discharged and notify the control unit 40.

(7) In the above embodiment, the reel 26 is described as an example of the component housing, but the component housing may be a component tray on which the component E is mounted.
