Detailed Description

Accordingly, the supply rack can automatically prepare 1 st component container or more to be supplied from the plurality of 1 st component containers, and therefore, when the 1 st component container is supplied to the manufacturing apparatus, the 1 st component container held in the supply unit may be supplied. In other words, when the 1 st component container is supplied to the manufacturing apparatus, it is not necessary to select 1 or more 1 st component containers to be supplied from the plurality of 1 st component containers. Thus, the 1 st component container can be efficiently supplied to the manufacturing apparatus by the supply rack.

Further, for example, the supply rack may further include a control unit that controls the moving unit so that one or more 1 st component containers are moved from the 1 st storage unit to the supply unit before a supply device for moving the one or more 1 st component containers to the manufacturing apparatus is connected to the supply rack.

Therefore, 1 st component container 1 or more to be supplied can be prepared in advance before the supply device is connected to the supply rack, so that the 1 st component container can be supplied to the manufacturing device more efficiently by the supply rack.

Further, for example, the supply unit may supply two or more of the 1 st component containers to the supply device together when the two or more of the 1 st component containers are held in a state where the supply device is connected to the supply rack.

Accordingly, 1 or more 1 st component containers can be supplied to the supply device in a short time, so that the 1 st component containers can be efficiently supplied to the supply device by the supply rack.

Further, for example, the supply device may have a plurality of 1 st holding portions capable of holding the 1 st component container or the 2 nd component container in which no component is held, the supply device may have a plurality of 2 nd holding portions corresponding to the plurality of 1 st holding portions, and the 2 nd holding portions may hold one or more 1 st component containers, and the control portion may control the moving portion so that one or more 1 st component containers are moved to one or more 2 nd holding portions corresponding to one or more 1 st holding portions in which the 1 st component container or the 2 nd component container is not held, among the plurality of 2 nd holding portions.

Thus, even when the 2 nd component container is held in the supply device, the supply rack does not need to move the position of the 2 nd component container, and supplies 1 or more 1 st component containers to the supply device.

Further, for example, the supply rack may further include a recovery unit that recovers the 2 nd component containers held in one or more of the 1 st holding units together in a state where the supply device is connected to the supply rack.

Accordingly, 1 or more 2 nd component containers can be collected together, so that the supply rack can perform a collection operation more efficiently than a case where 1 or more 2 nd component containers are collected in sequence.

Further, for example, the supply rack may further include a mounting portion on which one or more of the 2 nd component containers collected by the collection portion is temporarily mounted, and the control portion may control the collection portion and the supply portion so that at least a part of a collection operation of the collection portion for collecting one or more of the 2 nd component containers from the 1 st holding portions and then moving the collection portion to the mounting portion and a supply operation of the supply portion for supplying one or more of the 1 st component containers to the 1 st holding portions after starting the movement from the supply portion to the 1 st holding portions are performed in parallel.

Accordingly, the feeding operation of the 1 st component container to the feeding device and the collecting operation of the 2 nd component container to the feeding rack are partially performed in parallel, and therefore both the feeding operation and the collecting operation can be performed efficiently by the feeding rack.

Further, for example, the supply rack may further include a 2 nd storage unit that stores a plurality of the 2 nd component containers, and the control unit may control the collection unit so that one or more of the 2 nd component containers placed on the placement unit are rearranged and moved to the 2 nd storage unit.

Thus, the 2 nd component container can be efficiently stored by rearranging the 2 nd component container in the 2 nd storage section without any gap.

Further, for example, the 2 nd storage unit may be located above the 1 st storage unit.

Thus, the supply rack in which the 2 nd storage unit is located above the 1 st storage unit can be realized.

Further, for example, the supply rack may include a plurality of the 2 nd storage units.

Accordingly, since more 2 nd component containers can be stored than in the case where 1 2 nd storage units are provided, the number of times that the worker collects the 2 nd component containers can be reduced, for example.

Further, for example, the control unit may control the collection unit to move the 2 nd component container to one of the 2 nd storage units preferentially over the other 2 nd storage units of the plurality of 2 nd storage units so that the largest number of the 2 nd component containers are stored in the one of the 2 nd storage units.

Thus, the 2 nd component container can be stored efficiently.

Further, for example, the supply rack may further include a connection portion connected to the supply device, the connection portion being located at one end side of the supply rack, and the 1 st storage portion being located at the other end side opposite to the one end side.

Thus, when the supply device is capable of autonomously supplying the 1 st component container to the manufacturing device, the automation area and the area where the worker is located can be separated, so that the safety is improved.

Further, for example, each of the plurality of 1 st component containers may have a tag storing 1 st component information indicating a type of the contained component, and the supply rack may further include a reading unit configured to obtain the 1 st component information from the tag of each of the plurality of 1 st component containers stored in the 1 st storage unit.

Thus, the supply rack can easily obtain the 1 st component information of the 1 st component container from the tag.

Further, for example, the supply rack may further include an obtaining unit that obtains, from a management device that manages the manufacturing device, 2 nd component information indicating a type of component that needs to be supplied to the manufacturing device, and the moving unit may take out one or more 1 st component containers from the 1 st storage unit and move the 1 st component containers to the supply unit based on the 1 st component information and the 2 nd component information.

Thus, the supply rack can prepare 1 or more 1 st component containers using the 2 nd component information from the management device.

For example, the plurality of manufacturing apparatuses to which the 1 st component container is supplied from the supply rack may be provided, the 2 nd component information may include information indicating a type of a component to be supplied to each of the plurality of manufacturing apparatuses, and the moving unit may move one or more 1 st component containers to the supply unit so that the one or more 1 st component containers are arranged in order of supplying the 1 st component containers to the plurality of manufacturing apparatuses.

Accordingly, 1 or more 1 st component containers can be supplied to the component mounting device in a shorter time since 1 or more 1 st component containers do not need to be rearranged in the supply device.

For example, the supply rack may further include a notification unit that notifies that the number of the 1 st component containers stored in the 1 st storage unit is equal to or less than a predetermined number when the number of the 1 st component containers stored in the 1 st storage unit is equal to or less than the predetermined number.

Thus, the occurrence of the component shortage of the 1 st component container in the 1 st storage unit can be suppressed.

Further, for example, the supply rack may include a plurality of the 1 st storage units.

Accordingly, since more 1 st component containers can be stored than in the case where 1 st storage unit is 1, the number of times that the worker supplies the 1 st component containers to the 1 st storage unit can be reduced by the supply rack.

Further, a production system according to an aspect of the present disclosure includes: the above-mentioned supply rack; and a manufacturing apparatus for performing a predetermined operation on the substrate, the manufacturing apparatus receiving the supply of the 1 st component container from the supply rack.

Thus, the same effects as those of the supply rack described above can be achieved.

Further, for example, the production system may further include a supply device to which one or more 1 st component containers are supplied from the supply unit, and the supply device may transfer the supplied one or more 1 st component containers to the manufacturing device.

Thus, in the case where the supply device is an automatic device, automation can be realized from the time of moving the 1 st component container to be supplied to the manufacturing device to the time of supplying the 1 st component container.

Further, for example, the production system may further include a parts warehouse for storing the plurality of 1 st parts containers supplied to the manufacturing apparatus, and the supply rack may temporarily store the plurality of 1 st parts containers supplied from the parts warehouse to the manufacturing apparatus.

Thus, the supply rack can function as a buffer for temporarily storing the 1 st component container, and for example, the 1 st component container can be efficiently supplied to the manufacturing apparatus even if the component warehouse is located at a position remote from the manufacturing apparatus.

Further, a supply method according to an aspect of the present disclosure is a supply method for a supply rack for supplying a 1 st component container containing a plurality of components used in a manufacturing apparatus for performing a predetermined operation on a substrate to the manufacturing apparatus, the supply rack including: a 1 st storage unit configured to store a plurality of the 1 st component containers; a supply unit configured to hold a plurality of the 1 st component containers and supply the held 1 st component containers to the outside of the supply rack; and a moving unit that takes out the 1 st component container from the 1 st storage unit and moves it to the supply unit, wherein in the supply method, the moving unit takes out one or more 1 st component containers that are required to be supplied to the manufacturing apparatus next from among the 1 st component containers stored in the 1 st storage unit and moves it to the supply unit.

Thereby achieving the same effect as the supply rack.

The embodiments are described below with reference to the drawings.

The embodiments described below are examples showing the summary or the concrete of the present disclosure. The numerical values, shapes, components, arrangement positions of components, connection patterns, steps, order of steps, and the like shown in the following embodiments are examples, and the gist of the present disclosure is not to be limited. The following embodiments will be described with reference to the accompanying drawings, which are not intended to limit the scope of the invention.

The drawings are schematic representations, not strict representations. Therefore, for example, the scale is not uniform in each drawing. In the drawings, substantially the same members are denoted by the same reference numerals, and repetitive description thereof will be omitted or simplified.

In the present specification and the drawings, the X-axis, the Y-axis, and the Z-axis are three axes of a three-dimensional rectangular coordinate system of the right-hand system. In the embodiment, the X-axis direction is a direction in which the mounting substrate manufacturing line extends, the Y-axis direction is a direction in which the plurality of mounting substrate manufacturing lines are aligned, and the Z-axis direction is a direction orthogonal to the floor of the manufacturing shop in which the mounting substrate manufacturing line is disposed. In the present specification, "upper" means the positive Z-axis side, and "plan view" means a view seen from the Z-axis direction.

In the present specification, terms indicating the relationship between elements such as orthogonal and phase, and terms indicating the shape of an element such as straight line and rectangular are used, and numerical values and numerical ranges are used to indicate not only the strict expression but also expressions having practically equivalent ranges, for example, expressions including a difference of about several percent (for example, about 10%).

(embodiment)

The production system according to the present embodiment will be described below with reference to fig. 1 to 12.

[1. Structure of production System ]

First, the configuration of the production system according to the present embodiment will be described with reference to fig. 1 to 6. Fig. 1 is a diagram showing a schematic configuration of a production system 1 in the present embodiment. The layout of the production plant F (an example of a manufacturing plant) will be described with reference to fig. 1.

As shown in fig. 1, a manufacturing shop F such as a manufacturing factory is configured to include a plurality of mounting board manufacturing lines L, and is divided into four directions by a predetermined wall. In the production facility F, a plurality of component mounting devices 20, a plurality of supply devices 40, and a supply rack 100 that constitute the mounting substrate manufacturing line L are arranged.

The component mounting apparatus 20 is an example of a manufacturing apparatus that performs a predetermined operation on a substrate, and in the present embodiment, performs a soldering operation of components (for example, electronic components) on the substrate. The component mounting device 20 is disposed in a production area a in which a mounting substrate having electronic components soldered on a substrate is manufactured.

In the component mounting apparatus 20, since the components are consumed, it is necessary to supply (supplement) a component container, which is a container for containing a plurality of components, to the component mounting apparatus 20 at the time of operation of the production plant F. In the present embodiment, the component mounting apparatus 20 receives the supply of 1 or more component containers stored in the supply rack 100 (held by a supply unit 130 shown in fig. 2, 5, 6, etc., described later).

The supply device 40 is an example of a working robot, and supports the operation of supplying a component container for containing components consumed in the manufacturing apparatus such as the component mounting apparatus 20 to the manufacturing apparatus (for example, the operation of transporting the component container to the vicinity of the manufacturing apparatus), or supplies the component container (for example, the component container is supplied to the manufacturing apparatus instead of the worker H). In the present embodiment, the feeder 40 is mounted on an automated guided vehicle (AGV: automated GuidedVehicle) (AGV 80 shown in fig. 5), and moves by the AGV80, but the feeder 40 itself may have a self-propelled function. In the present embodiment, the supply device 40 supplies the component container to the component mounting device 20. In the following description, the feeder 40 is described as feeding the component container even when the feeder 40 is mounted on the AGV80 and moved to feed the component container.

The supply rack 100 is a rack for temporarily storing (for relay) components for storing a plurality of components used in the component mounting apparatus 20, in order to supply the component mounting apparatus 20 with the component storage. As will be described later, the supply rack 100 is configured such that the supply rack 100 stores a plurality of component containers, and can collect 1 or more component containers that need to be supplied to the component mounting device 20 from the plurality of component containers in accordance with the inventory of components of the component mounting device 20, and supply the components to the outside of the supply rack 100. In other words, the supply rack 100 has a function of automatically and previously preparing 1 or more component containers that are required to be supplied next to the component mounting device 20.

The supply rack 100 functions as a buffer for temporarily storing a plurality of component containers that may be supplied to the component mounting apparatus 20 from a warehouse 60 for storing the plurality of component containers supplied to the manufacturing apparatus including the component mounting apparatus 20. The supply rack 100 is disposed between the warehouse 60 and the production area a (for example, the mounting substrate manufacturing line L). Thus, the component container can be efficiently replenished to the component mounting device 20.

The management device 50 is an information processing device that manages the production system 1, and is communicably connected to each of the manufacturing device such as the component mounting device 20, the supply device 40, the warehouse 60, and the supply rack 100.

In the production system 1, in the production shop F, the component containers temporarily stored in the supply rack 100 are held and moved by the supply device 40, and the component containers are transported by the supply device 40 and supplied to the manufacturing apparatus including the component mounting device 20.

Here, the component receiver is a case that receives components. The component container is, for example, a box in which a carrier tape is stored. The component container has a hollow portion, and for example, a spirally wound carrier tape (a roll-shaped carrier tape that is not wound around a reel) or a carrier tape wound around a reel is accommodated in the hollow portion. The component container may further include a tape feeder (not shown) for feeding the carrier tape at intervals. The belt conveyor is composed of a sprocket provided in the vicinity of the lower part of the component suction position, a motor for rotationally driving the sprocket, and the like. Such a component receiver may be a component receiver having a function of a feeder. The component container may be a case having a feeder function and a storage function.

The positions, arrangement orientations, occupied areas, and numbers of the component mounting devices 20, the supply devices 40, and the supply racks 100 disposed in the production shop F are examples, and are not limited to the example of fig. 1, and may be appropriately designed according to the conditions of the production shop F. In the production shop F, a conveyance path R for driving the supply device 40 is formed. The supply device 40 travels on this conveyance path R, and conveys the component container or the like containing the electronic components from the supply rack 100 to the production area a. The conveyance path R is defined by physical information such as a logo and a guidance line provided in the production facility F, or path information, map information, and the like stored in the storage unit 45 (see fig. 2) in the supply device 40. In fig. 1, for convenience of explanation, the conveyance path R is simply represented as a straight line or a rectangular shape, but is not limited thereto. The conveyance path R may be provided in various shapes (e.g., zigzag, oblique directions, etc.) as needed.

In addition, the warehouse 60 is provided outside the production plant F, but may also be provided inside the production plant F.

In the example of fig. 1, 3 mounting board manufacturing lines L are provided in a straight line in the production area a. Each of the mounting substrate manufacturing lines L is constituted by a plurality of manufacturing apparatuses including a component mounting apparatus 20, by which a series of manufacturing processes such as solder printing on a substrate, mounting (assembling) electronic components to a substrate, reflow soldering, and the like are automatically performed. The mounting substrate manufacturing line L includes a substrate supply device 11, a screen printing device 12, a printing solder inspection device 13, a component mounting device 20, a component mounting state inspection device 14, a reflow soldering device 15, a mounting substrate inspection device 16, a mounting substrate recovery device 17, and a display device 18.

The substrate supply device 11 sequentially supplies the conveyed substrates to the screen printing device 12. The screen printing device 12 performs screen printing on a substrate to be supplied, for example, solder paste or the like, at a predetermined position. The print soldering inspection device 13 inspects the state of solder printed on the substrate.

Each of the plurality of component mounting devices 20 mounts an electronic component on a position where solder paste is printed by the screen printing device 12 by using a mounting head 27 (see fig. 3). The component mounting apparatus 20 further includes a component supply unit 23 (see fig. 3), and the component supply unit 23 is configured to supply electronic components to the mounting head 27. The component supply unit 23 is provided with a component container in which electronic components are stored, and supplies the components of the component container to a position where the mounting head 27 of the component mounting apparatus 20 can hold the components. When the electronic components of the component supply unit 23 are used and the number of remaining components is small, the worker H or the supply device 40 replaces the electronic components with a new component container from the supply rack 100. In the example of fig. 1, since a plurality of electronic components of different types are mounted on a substrate, a plurality of component mounting devices 20 (3 in this embodiment) are used. Each of the plurality of component mounting devices 20 is a device to which the supply device 40 supplies the component container.

The component mounting state inspection device 14 inspects the state of the electronic component mounted on the substrate. The reflow soldering apparatus 15 performs soldering on the substrate on which the electronic component is mounted. That is, the reflow apparatus 15 is a so-called heating furnace, heats and melts solder on a substrate, and then cools and solidifies the solder to solder electronic components on the substrate. The mounting board inspection device 16 inspects the mounting board after the soldering by the reflow soldering device 15. The mounting substrate collection device 17 collects the substrates on which the electronic components are soldered, and conveys the substrates to the outside of the mounting substrate manufacturing line L.

The display device 18 is configured to include a display panel such as a liquid crystal panel, for example, and is suspended from the ceiling of the production plant F by a predetermined holding member so as to be adjustable to an arbitrary posture. In each mounting substrate manufacturing line L, a pair of display devices 18 are disposed back to back. Thus, the worker H can easily and quickly visually confirm the display device 18 at any place in the production shop F.

The display device 18 may have a function as a notifying unit that notifies the worker H that the number of component containers stored in the supply rack 100 is equal to or less than a predetermined number by using an image. The display device 18 may be communicably connected to the management device 50 or the supply rack 100.

Next, the structure (mainly, functional structure) of each component of the production system 1 and the structure of the component mounting device 20 will be described with reference to fig. 2 and 3. Fig. 2 is a block diagram showing a functional configuration of the production system 1 in the present embodiment. Fig. 3 is a diagram showing the structure of the component mounting apparatus 20 in the present embodiment. Fig. 3 is a plan view of the component mounting apparatus 20 shown in fig. 1 from above.

The arrow mark of the broken line in fig. 2 indicates the moving path of the component container in the supply rack 100. Hereinafter, a new component container in which components are stored will be referred to as a component container 210, and an empty component container will be referred to as a component container 220. The new component container is a new product of the component container (unused component container), but may be a component container in which the number of components to be stored is equal to or greater than a predetermined number. The empty component container is a component container in which the contained components are zero, but the number of the contained components may be smaller than a predetermined number.

As shown in fig. 2, the component mounting device 20 is configured to be capable of communicating with the supply device 40, the management device 50, and the supply rack 100. As shown in fig. 3, the component mounting apparatus 20 has a pair of substrate transport mechanisms 22 arranged along the X-axis direction (substrate transport direction) in the center of the main body base 21. The substrate conveying mechanism 22 includes a pair of conveyor belt portions 22A extending along the X-axis direction, and a substrate holding portion 22B provided by connecting the pair of conveyor belt portions 22A in the Y-axis direction (a direction orthogonal to the X-axis direction in a plan view). A substrate holder 22C for fixedly holding a substrate is disposed at each end of the substrate holding portion 22B. The substrate conveying mechanism 22 conveys the substrate supplied from the upstream side device (for example, the printing inspection device 13) and determines and holds the position.

A pair of front and rear component supply units 23 are provided on both sides (Y-axis positive side and Y-axis negative side) of the substrate conveyance mechanism 22. A pair of wall portions 21A are provided on both sides of the main body base portion 21, and the component supply portions 23 are disposed in spaces surrounded by the pair of wall portions 21A. Each of the component supply sections 23 has a feeder base 23A provided with a slot 23B, and a plurality of tape feeders 23C are mounted in the slot 23B side by side as feeders.

Further, the component mounting apparatus 20 has a feeder wagon 24. The feeder wagon 24 includes a carrying portion 24A on the lower side of which a plurality of casters are arranged, and a plurality of reel stock portions 24B on the upper side of the carrying portion 24A which are arranged in different layers from each other. The reel stock portions 24B each house a component container, and the carrier tape housing the electronic component is pulled out from each component container, thereby supplying the electronic component to the tape feeder 23C. Accordingly, the tape feeder 23C sends the carrier tape at intervals in the tape sending direction, and supplies the electronic components through the mounting head 27 of the component mounting device 20.

Further, a pair of Y-axis table mechanisms 25 are disposed along the Y-axis direction at both ends of the upper surface of the main body base portion 21 in the X-axis direction. Further, between the pair of Y-axis table mechanisms 25, an X-axis table mechanism 26 is installed so as to be capable of sliding along the Y-axis direction, and is installed so as to bridge between these Y-axis table mechanisms 25. The mounting head 27 is mounted on the front end portion of the X-axis table mechanism 26 so as to be slidable along the X-axis direction. The X-axis table mechanism 26 and the Y-axis table mechanism 25 are each constituted by a linear guide driving mechanism.

The mounting head 27 is a multi-head having a plurality of holding heads, and a component holding nozzle (not shown) is mounted on the lower end portion of each holding head. The component holding nozzle vacuum-sucks and holds the electronic component by air pressure, and lifts and lowers the electronic component. The mounting head 27 further includes a Z-axis lifting mechanism (not shown) for lifting and lowering the component holding nozzle, and a θ -axis rotation mechanism (not shown) for rotating the component holding nozzle about a nozzle axis (for example, Z-axis). By driving the Y-axis table mechanism 25 and the X-axis table mechanism 26, the mounting head 27 can be positioned at an arbitrary position in the horizontal plane (XY plane). Accordingly, the mounting head 27 removes the electronic component from the removal position of the tape feeder 23C of the component supply unit 23 through the component holding nozzle.

Further, a component recognition camera 28 is disposed between the component supply unit 23 and the substrate conveyance mechanism 22. When the mounting head 27, which has taken out the electronic component from the component supply section 23, moves above the component recognition camera 28, the component recognition camera 28 photographs the electronic component held by the mounting head 27. The recognition processing is performed on the imaging result, whereby recognition, position detection, and the like of the electronic component are performed. A substrate recognition camera 29 is fixedly provided on the mounting head 27, and the substrate recognition camera 29 is disposed on the lower surface side of the X-axis table mechanism 26 and moves integrally with the mounting head 27. By the movement of the mounting head 27, the substrate recognition camera 29 moves above the substrate positioned by the substrate conveyance mechanism 22, and photographs the substrate.

When the component container 210 is replenished to the 1 st storage section 121, the lid 111 is opened, and the component container 210 is supplied to the 1 st storage section 121 from the opening of the 1 st storage section 121 that is exposed. For example, the worker H supplies the component container 210 to the 1 st storage sections 121 and 122. For example, the component container 210 may be supplied from the warehouse 60 to the supply rack 100 using the cart 70 (see fig. 5).

An opening 113 is formed in the housing 110. The opening 113 is an opening for exposing the component container 220 stored in the 2 nd storage sections 161 and 162 (i.e., the empty component container). By providing the opening 113, the worker H can know whether or not the component container 220 is stored by looking at the opening 113. Further, the worker H can easily take out (collect) the component container 220 from the supply rack 100 through the opening 113.

The 1 st storage units 121 and 122 are frame-shaped members capable of storing the plurality of component containers 210. The 1 st storage units 121 and 122 have a comb-shaped holding unit (bottom surface) in which the plurality of component containers 210 are aligned and held in the X-axis direction. The component container 210 is supplied to the 1 st storage units 121 and 122 from the opening on the negative side of the Y axis.

The 1 st storage part 121 has an opening 121a extending in the X-axis direction formed in an upper part thereof, and the 1 st storage part 122 has an opening 122a extending in the X-axis direction formed in an upper part thereof. The openings 121a and 122a are formed, for example, at positions of the labels 211 provided in the component container 210. The 1 st reading section 103a reads the 1 st component information from the tag 211 by moving over the openings 121a and 122a.

The 1 st storage units 121 and 122 are located on the negative side of the Y axis in the supply rack 100 in a plan view. This is an example in which the 1 st storage units 121 and 122 are located on the other end side of the supply rack 100.

The 1 st storage sections 121 and 122 are made of metal or resin, but are not limited thereto.

The number of 1 st storage units provided in the supply rack 100 is not limited to 2 (1 st storage units 121 and 122), but may be 1 or 3 or more.

The supply unit 130 can hold a plurality of component containers 210, and supply the held component containers 210 to the outside of the supply rack 100. The supply unit 130 holds 1 or more component containers 210 to be supplied next to the component mounting device 20 among the plurality of component containers 210. The supply portion 130 has a plurality of channels (grooves) capable of holding the component container 210. The channel is an example of the 2 nd holding portion.

The plurality of channels (grooves) of the supply portion 130 have shapes corresponding to the plurality of channels (grooves) of the component holding portion 43. The plurality of channels of the supply unit 130 corresponding to the plurality of channels of the component holding unit 43 means that, for example, the intervals and the number of the respective channels are equal.

The 1 st moving unit 104a takes out 1 or more component containers 210 to be supplied to the component mounting apparatus 20 from among the plurality of component containers 210 stored in the 1 st storage units 121 and 122 based on the 1 st component information and the 2 nd component information, and moves the component containers to the supply unit 130. The 1 st moving section 104a has 2 or more plate-like members (for example, sheet metal) extending in the Y-axis direction, and the members are used to pull out (for example, lift up) the member holders 210 (1 or more member holders 210) to be supplied from the 1 st storage sections 121 and 122, and the 2 or more plate-like members are inserted in the upward direction through gaps of the comb-shaped holding sections (bottom surfaces) as intervals corresponding to the width of the member holders 210 to be supplied, so that the member holders 210 to be supplied are lifted up and moved in the Y-axis forward direction. Fig. 6 shows a state in which the 1 st moving unit 104a lifts the desired component container 210 to the Y-axis positive direction. The 1 st moving unit 104a takes out the component container 210 from the 1 st storage unit of the 1 st storage units 121 and 122, which is not opened with the cover (the cover 111 or 112), and moves the component container to the supply unit 130.

The 1 st moving unit 104a is mounted on an axis extending in the X-axis direction so as to be capable of sliding along the axis, and moves to the X-axis positive side while maintaining the state of the component container 210 to be supplied. The 1 st moving unit 104a moves the component container 210 to the channel of the supply unit 130. By repeating this series of operations, for example, only 1 or more component containers 210 that are subsequently supplied to the component mounting apparatus 20 are held in the supply unit 130. The 1 st moving unit 104a is mounted on the axis so as to be slidable along the axis extending in the Y-axis direction, and can move the supply unit 130 holding 1 or more component containers 210 to the Y-axis positive side.

The collection unit 140 collects, for example, 1 or more component containers 220 together. The collection unit 140 has a plurality of channels 141, and the component container 220 can be held in the channels 141. The channel 141 is formed of, for example, a channel (trench) extending in the Y-axis direction. The simultaneous collection means that, for example, 1 or more component holders 220 held in the component holding portion 43 of the supply device 40 are collected simultaneously in 1 operation (for example, a collection operation of the claw portion 142 shown in fig. 11B described later).

The connection of the supply device 40 to the supply rack 100 means a state in which the component container 220 held by the component holding portion 43 of the supply device 40 can be moved to the collection portion 140 or a state in which the component container 210 held by the supply portion 130 can be supplied to the component holding portion 43.

The 2 nd moving unit 104b is mounted on the axis so as to be slidable along the axis extending in the Y-axis direction, and can move the collecting unit 140 in the X-axis direction. The 2 nd moving unit 104b is mounted on the axis so as to be slidable along the axis extending in the Z-axis direction, and can move the recovery unit 140 in the Z-axis direction. The 2 nd moving unit 104b performs operations from temporary storage in the placement unit 150 to storage in the 2 nd storage units 161 and 162 with respect to the component containers 220 collected by the collection unit 140.

The mounting portion 150 is a frame-shaped member capable of storing a plurality of component containers 220, and temporarily mounts (holds) 1 or more component containers 220 collected by the collection portion 140. The mounting portion 150 mounts 1 or more component containers 220 as they are, for example, in a state of being recovered from the supply device 40. Each of the 1 or more component containers 220 placed on the placement unit 150 is extracted by the 2 nd reading unit 103b, and the 1 st component information including at least the width of the component container 220 is extracted.

The mounting portion 150 has a holding portion (bottom surface) formed with a channel (groove), and the holding portion holds 1 or more component containers 220 received therein while being aligned in the X-axis direction.

In the present embodiment, the placement unit 150 is located above (on the positive Z-axis side of) the 1 st storage units 121 and 122. For example, in a plan view, the placement unit 150 is located at a position not overlapping with the 1 st storage units 121 and 122. The placement portion 150 is shielded by the housing 110, for example, and cannot be visually checked from the outside.

The 2 nd storage sections 161 and 162 are frame-shaped members capable of storing the plurality of component containers 220. The 2 nd storage units 161 and 162 have a holding unit (bottom surface) formed with a plurality of channels (grooves), and receive 1 or more component containers 220 temporarily stored in the mounting unit 150, and the received 1 or more component containers 220 are aligned and held in the X-axis direction in the holding unit. The parts to the parts containers 220 of the 2 nd storage sections 161 and 162 are supplied from the opening on the Y-axis positive side.

In the present embodiment, the 2 nd storage sections 161 and 162 are located above (on the positive Z-axis side of) the 1 st storage sections 121 and 122. For example, the 2 nd storage sections 161 and 162 overlap with at least a part of the 1 st storage sections 121 and 122 in a plan view. The 2 nd storage sections 161 and 162 are located on the Y-axis negative side of the supply rack 100 in a plan view. This is an example in which the 2 nd storage sections 161 and 162 are located at the other end side of the supply rack 100. In the present embodiment, the 1 st storage units 121 and 122 and the 2 nd storage units 161 and 162 are located at the other end side of the supply rack 100.

The number of the 2 nd storage units (the 2 nd storage units 161 and 162) included in the supply rack 100 is not limited to 2, and may be 1 or 3 or more. The number of the 2 nd storage sections 161 and 162 provided in the supply rack 100 may be the same as or different from the number of the 1 st storage sections 121 and 122.

The connection portion 170 is a portion to which the supply device 40 is connected, and has a function of determining a position of the supply device 40 when the supply device is connected to the supply rack 100. The component holding portion 43 of the supply device 40 abuts against the connecting portion 170, and thereby the supply device 40 is connected to the supply rack 100.

The connection portion 170 is located on the Y-axis positive side of the 1 st storage portions 121 and 122 in the supply rack 100 in a plan view. This is an example in which the connection portion 170 is located at one end side of the supply rack 100. In the present embodiment, the connection portion 170 and the 1 st storage portions 121 and 122 are disposed on opposite sides of the supply rack 100 as a center in a plan view. In the present embodiment, one end side is the side (Y-axis positive side) on which the mounting substrate manufacturing line L is disposed, but the present invention is not limited thereto.

[2 ] action of production System ]

Next, the operation of the production system 1 configured as described above will be described with reference to fig. 7 to 12. Fig. 7 is a sequence diagram showing the operation of the production system 1 in the present embodiment.

As shown in fig. 7, the supply rack 100 detects supply (replenishment) of the component container 210 (S10). The control unit 102 of the supply rack 100 detects supply to the component containers 210 of the 1 st storage units 121 and 122, for example, based on the opening and closing of the covers 111 and 112, the detection results of the sensors, and the like.

Next, the 1 st reading unit 103a reads the 1 st component information from the tag 211 of the component container 210 using the detected supply of the component container 210 as a trigger or at predetermined time intervals (S20). The 1 st reading unit 103a reads the 1 st component information from the tag 211 of each of the plurality of component containers 210 stored in the 1 st storage units 121 and 122. The 1 st reading unit 103a associates the 1 st component information thus read with the position of the component container 210, and stores the information in the storage unit 106 (S30). The 1 st reading unit 103a reads the tag 211, for example, under the control of the control unit 102.

Next, the control unit 102 transmits the 1 st component information read in step S20 to the management device 50, and the management device 50 receives the 1 st component information from the supply rack 100 (S40). The management device 50 may store the received 1 st component information in the storage unit 55.

Next, the control unit 52 of the management device 50 determines the parts (types of parts) to be replenished to the part mounting device 20 based on the inventory, production conditions, production plan data, and the like of the parts of the part container mounted on the part mounting device 20 (S50). The control unit 52 determines that the stock of components in the component container is equal to or less than a predetermined number (3 rd number) or is predicted to be equal to or less than the predetermined number as components to be replenished. The control unit 52 determines the components to be replenished for each of the plurality of component mounting apparatuses 20.

Next, when there is a component to be replenished, the control unit 52 transmits information for instructing to prepare the component to the supply rack 100, and the supply rack 100 receives information for instructing to prepare the component from the management device 50 (S60). The information may include, for example, the 2 nd component information indicating the type of the component to be supplied to the component mounting apparatus 20, or may include information indicating which position of the 1 st storage unit 121 or 122 the component container 210 is to be supplied (moved to the supply unit 130). The information may include information indicating which channel of the supply unit 130 the component container 210 stored in which position of the 1 st storage unit 121 or 122 is moved.

Next, the control unit 102 takes out the necessary component container 210 from the 1 st storage units 121 and 122 based on the information indicating the preparation of the components, and moves the component container to the supply unit 130 (S70).

Next, the control unit 52 transmits information for instructing the feeding device 40 to be transported to the feeding rack 100 to the AVG80, and the AVG80 receives the instructed information (S80). Further, the AVG80 connects the supply device 40 to the supply rack 100 (S90).

Next, the supply rack 100 collects the component containers 220 (empty component containers) and supplies the component containers 210 (S100). In the supply rack 100, when the component holders 220 are held by the component holding portions 43 of the supply device 40, all the component holders 220 are collected. For example, the supply rack 100 recovers all of the component containers 220 together. The collected component container 220 is temporarily placed on the placement unit 150. The supply rack 100 supplies the component container 210 held in the supply unit 130 to the supply device 40.

Next, when the supply of the component containers 210 from the supply rack 100 is completed, the control unit 52 transmits information instructing the conveyance of the supplied component containers 210 to the component mounting device 20 to the AVG80, and the AVG80 receives the instructed information (S110). Then, the AVG80 conveys the supply device 40 to the component mounting device 20 (S120).

Next, the rack 100 rearranges the component containers 220 temporarily stored in the mounting portion 150 (empty component containers collected in step S100) (S130). Specifically, the control unit 102 of the supply rack 100 takes out the component container 220 temporarily stored in the mounting unit 150 and moves it to any channel of the 2 nd storage units 161 and 162.

The instructions from the management device 50 in step S80 and step S110 shown in fig. 7 may be performed in parallel, for example.

Next, with respect to step S70 shown in fig. 7, description will be made with reference to fig. 8 to 9D. Fig. 8 is a flowchart showing the details of step S70 shown in fig. 7.

As shown in fig. 8, the control unit 102 controls the 1 st moving unit 104a so that the component container 210 to be supplied to the component mounting apparatus 20 is moved from the 1 st storage units 121 and 122 to the supply unit 130 (S210). The control unit 102 can be said to move the component container 210 that needs to be supplied to the component mounting apparatus 20 from the 1 st storage units 121 and 122 to the supply unit 130. The control unit 102 may control the 1 st moving unit 104a to move 1 or more component containers 210 to the supply unit 130 so that 1 or more component containers 210 are arranged in order of supplying the component containers 210 to the plurality of component mounting devices 20.

Accordingly, since the operation of rearranging 1 or more component containers 210 in the supply device 40 can be omitted, the time required for the component containers 210 to be supplied to the component mounting device 20 after the component containers 210 are supplied from the supply unit 130 to the supply device 40 can be shortened. Further, the supply device 40 may be said to be capable of being directly transported to the component mounting device 20 in the order in which the 1 or more component containers 210 received from the supply unit 130 are arranged, without performing the operation of rearranging the 1 or more component containers 210 received from the supply unit 130.

The operation of transferring the component container 210 from the 1 st storage units 121 and 122 to the supply unit 130 (transferring operation) will be described with reference to fig. 9A to 9D.

Fig. 9A is a view 1 for explaining the moving operation of the supply rack 100 in the present embodiment. Fig. 9A is a view schematically showing the inside of the supply rack 100 in a state where the component container 210 to be supplied is not held in the supply portion 130 (not prepared). Fig. 9A shows the interior of the supply rack 100 before receiving information indicating preparation of components.

Fig. 9B is a view 2 for explaining the moving operation of the supply rack 100 in the present embodiment. Fig. 9B shows the interior of the supply rack 100 after receiving information indicating preparation of the components.

As shown in fig. 9B, the 1 st moving part 104a moves slidably to the channels of the 1 st storage parts 121 and 122 storing the parts to be supplied 210, and the parts storage 210 held in the comb-shaped holding parts (bottom surfaces) of the 1 st storage parts 121 and 122 are lifted up from below by the plate-like parts 104a1, whereby the parts storage 210 to be supplied are extracted from the 1 st storage parts 121 and 122. Fig. 9B illustrates an example immediately before the plate-like member 104a1 is lifted up from the member storage 210 of the 1 st storage unit 121. The plate-like member 104a1 is movable in the Z-axis direction and the Y-axis direction in fig. 9B. In other words, the plate-like member 104a1 can move the member receiver 210 in the Z-axis direction and the Y-axis direction.

Fig. 9C is a 3 rd view for explaining the moving operation of the supply rack 100 in the present embodiment. Fig. 9C shows the 1 st moving unit 104a as it has taken out the component container 210 from the 1 st storage unit 121. The 1 st moving unit 104a moves slidingly in the X-axis negative direction until the position of the supply unit 130 after the component container 210 is taken out from the 1 st storage unit 121.

Fig. 9D is a view 4 for explaining the moving operation of the supply rack 100 in the present embodiment. Fig. 9D shows the inside of the supply rack 100 after all of the component containers 210 to be supplied are moved to the supply section 130. The component container 210 is moved to the supply unit 130 by the plate-like component 104a 1.

Referring again to fig. 8, the control unit 102 determines whether all the parts containers 210 to be supplied have been moved to the supply unit 130 (S220). The control unit 102 determines in step S220 whether or not all of the components included in the information for instructing preparation of the components from the management device 50 or the component container 210 have been moved to the supply unit 130.

When it is determined that all the parts containers 210 to be supplied have been moved to the supply unit 130 (yes in S220), the control unit 102 ends the processing, and when it is determined that all the parts containers 210 to be supplied have not been moved to the supply unit 130 (no in S220), returns to step S210, and moves the remaining parts containers 210 to the supply unit 130.

The control unit 102 may control the 1 st moving unit 104a so that all of the component containers 210 to be supplied are moved from the 1 st storage units 121 and 122 to the supply unit 130 before the supply device 40 for transporting the component containers 210 to be supplied to the component mounting device 20 is connected to the supply rack 100.

Next, with respect to step S100 shown in fig. 7, description will be made with reference to fig. 10 to 11G. Fig. 10 is a flowchart showing details of step S100 shown in fig. 7. Fig. 10 shows the operation after the supply device 40 is connected to the supply rack 100.

As shown in fig. 10, the control unit 102 recovers the component container 220 (empty component container) from the supply device 40 (S310).

Fig. 11A is a view 1 for explaining the collection operation and the supply operation of the supply rack 100 according to the present embodiment. Fig. 11A shows a state in which the connection portion 170 is connected to the supply device 40, for example, the connection portion 170 abuts against the component holding portion 43.

Fig. 11A shows a state in which 1 or more channels of the supply unit 130 corresponding to 1 or more channels of the component holding unit 43 that do not hold the component holders 210 and 220 are shifted from the state in which the component holders 210 need to be supplied, among the plurality of channels of the supply unit 130. Thus, the component container 220 can be efficiently (e.g., simultaneously) collected and supplied to the component container 210. Such movement of the component container 210 is controlled by the control unit 102. The control unit 102 may obtain information indicating which channel of the supply device 40 is empty from the supply device 40 or the management device 50 in advance.

The channels of 1 or more of the supply units 130 corresponding to the channels of 1 or more of the component holding units 43 are channels of the supply units 130 on the extension line of the empty channels of the component holding units 43 in a state where the component holding units 43 are close to or in contact with the supply units 130 (for example, in a state of fig. 11C), and are channels of the supply units 130 connected (connected) to the empty channels of the component holding units 43 in a state where the component holding units 43 are in contact with the supply units 130.

In fig. 11A, 11C to 11G, illustration of the placement portion 150 and the like is omitted. Since the illustration of the placement unit 150 is omitted, the symbol is indicated by a broken line lead line.

Fig. 11B is a view 2 for explaining the collection operation and the supply operation of the supply rack 100 in the present embodiment.

As shown in fig. 11B, the collection unit 140 moves the claw portion 142 with respect to the component container 220 to be collected, and retracts (moves toward the Y-axis positive side) the claw portion 142 after engaging the concave portion or the protrusion formed in the component container 220 with the tip end of the claw portion 142, thereby collecting the component container 220. The collection unit 140 may collect 1 or more component containers 220 together, or may collect 1 or more component containers 220 sequentially by 1 or a small number of the claws 142, for example, by having the same number of claws 142 as the number of channels of the component holding unit 43.

Fig. 11C is a view of fig. 3 for explaining the collection operation and the supply operation of the supply rack 100 in the present embodiment. Fig. 11C shows the state of the inside of the supply rack 100 after the recovery unit 140 recovers all the component containers 220 to be recovered. At this time, the component holding portion 43 does not hold the component receiver 220.

Referring again to fig. 10, the control unit 102 controls the 2 nd moving unit 104b to start moving the component container 220 (empty component container) collected in step S310 to the mounting unit 150 (S320).

Fig. 11D is a view 4 for explaining the collection operation and the supply operation of the supply rack 100 according to the present embodiment. In fig. 11D, in order to move the collection unit 140 having collected the component container 220 to the placement unit 150, the collection unit 140 is moved to the Z-axis positive side by the 2 nd moving unit 104b (see fig. 6). The direction of movement of the recovery unit 140 is not limited to the positive Z-axis, and the recovery unit 140 may be moved to a position other than between the supply unit 130 and the component holding unit 43. The recovery unit 140 is moved to the positive X-axis side, for example.

Referring again to fig. 10, the control unit 102 controls the 1 st moving unit 104a to move the component container 210 of the supply unit 130 to the supply device 40 (S330).

Fig. 11E is a view 5 for explaining the collection operation and the supply operation of the supply rack 100 according to the present embodiment. Fig. 11E shows a state in which the 1 st moving portion 104a moves the supply portion 130 to the component holding portion 43 side (the connection portion 170 side). In the state of fig. 11E, the supply portion 1×0 and the component holding portion 43 may abut.

Fig. 11F is a view 6 for explaining the collection operation and the supply operation of the supply rack 100 according to the present embodiment. Fig. 11F shows a state in which the 1 st moving portion 104a moves the component container 210 of the supply portion 130 to the component holding portion 43. When the supply unit 130 holds 2 or more component containers 210 in a state where the supply device 40 is connected to the supply rack 100, the 2 or more component containers 210 may be supplied to the supply device 40 (specifically, the component holding unit 43) together, or 2 or more may be supplied in sequence, one for each or 2 or more. The simultaneous supply means that, for example, 1 or more component holders 210 held by the supply unit 130 are simultaneously moved (supplied) by one operation (for example, a storage operation of a claw portion (not shown) provided in the 1 st moving unit 104 a).

Referring again to fig. 10, the control unit 102 controls the 2 nd moving unit 104b to move (move) the component container 220 to the mounting unit 150, and ends the operation of the collecting unit 140 to move the component container 220 to the mounting unit 150 (S340).

Fig. 11G is a view 7 for explaining the collection operation and the supply operation of the supply rack 100 according to the present embodiment. Fig. 11G shows a state in which the component container 220 held by the collection unit 140 is moved to the placement unit 150.

As described above, the control unit 102 controls the recovery unit 140 and the supply unit 130 so that at least a part of the recovery operation of recovering 1 or more component containers 220 from the plurality of channels of the component holding unit 43 and at least a part of the supply operation of moving (supplying) 1 or more component containers 210 to the component holding unit 43 after the recovery unit 140 starts to move from the supply unit 130 to the component holding unit 43 (the plurality of channels of the component holding unit 43) are performed in parallel. The control unit 102 may perform the collection operation and the supply operation at different timings (for example, start the supply operation after the collection operation is completed).

Next, with reference to fig. 12, description will be made regarding step S130 shown in fig. 7. Fig. 12 is a flowchart showing the details of step S130 shown in fig. 7. Fig. 12 shows a process of rearranging the component containers 220 temporarily stored in the mounting unit 150 to the 2 nd storage units 161 and 162.

As shown in fig. 12, the control unit 102 controls the 2 nd reading unit 103b to read the label 221 of the component container 220 of the mounting unit 150 (S410). In step S410, at least the widths of the component containers 220 of the mounting portion 150 may be obtained.

Thus, the control unit 102 can obtain the component container 220 of which width is temporarily stored at which position of the mounting unit 150.

Next, the control unit 102 determines the destination (channel to be the destination) in the 2 nd storage units 161 and 162 based on the empty channels of the 2 nd storage units 161 and 162 and the width of the component container 220 read by the 2 nd reading unit 103b in step S410 (S420). The control unit 102 determines the channel to be moved so that no empty channel occurs or the number of empty channels is minimized. The control unit 102 determines the channel of the movement destination so that the component container 220 is stored without a gap in the 2 nd storage units 161 and 162.

The control unit 102 may determine the destination so that the largest number of component containers 220 are stored in one of the 2 nd storage units 161 and 162, and may move the component containers 220 to the one 2 nd storage unit in preference to the other 2 nd storage units.

Next, the control unit 102 controls the collection unit 140 to rearrange 1 or more component containers 220 mounted on the mounting unit 150 and to shift to the determined channels of the 2 nd storage units 161 and 162 (S430).

Next, the control unit 102 determines whether or not the storage numbers of the 2 nd storage units 161 and 162 are the maximum number (S440). The control unit 102 determines yes in step S440 when the storage number of the component containers 220 in any one of the 2 nd storage units 161 and 162 is the largest (in other words, when no empty channel exists in any one of the 2 nd storage units 161 and 162).

Next, when determining that the storage number of at least one of the 2 nd storage units 161 and 162 is the maximum number (yes in S440), the control unit 102 notifies the notification unit 105 (S450), and when determining that the storage numbers of the 2 nd storage units 161 and 162 are not the maximum number (no in S440), the processing ends.

(other embodiments)

The supply rack and the like according to one or more aspects are described above with reference to the embodiments, but the present disclosure is not limited to these embodiments. Various modifications that can be made by those skilled in the art without departing from the spirit of the present disclosure may be included in the present disclosure, as well as forms that are formed by combining constituent elements in different embodiments.

For example, in the above embodiment, an example has been described in which a plurality of component containers, which may be component containers for housing the same type of component or component containers for housing different types of component, are housed in one 1 st storage unit. The width dimensions of the plurality of component containers may be the same or different from each other.

In the above embodiment, the example in which the supply device collects the empty component containers from the component mounting device and transfers the empty component containers to the supply rack has been described, but the supply device may hold at least new component containers and supply the components to the component mounting device.

In the above embodiment, the 1 st storage unit and the connection unit are disposed on the opposite sides (one end side and the other end side) of the supply rack, but the positional relationship between the 1 st storage unit and the connection unit is not limited thereto. The 1 st storage unit and the connection unit may be disposed, for example, concentrated on one end side or the other end side, or may be disposed adjacently. The adjacent arrangement means that, for example, in the case where the 1 st storage unit is provided on the Y-axis negative side of the supply rack, the connection unit is provided on the X-axis positive side or the X-axis negative side.

In the above embodiment, the example in which the component container held in the supply portion of the supply rack is conveyed by the supply device has been described, but the present invention is not limited thereto. The component container held in the supply unit can be transported by a worker and supplied to the component mounting device. Even in such a case, the component container to be supplied is moved to the supply unit, so that the worker can dispense with the task of searching for the component container, and the component container can be efficiently supplied to the manufacturing apparatus.

In the above embodiment, the example of the supply rack performing the operation of collecting empty component containers and the operation of supplying new component containers has been described, but at least the operation of supplying new component containers may be performed. In other words, the supply rack may not perform the operation of collecting the empty component containers. In this case, the supply portion is not limited to be movable in the Y-axis direction, and may be fixed to the connection portion.

In the above embodiment, the example in which the component container containing the component to be supplied next is moved to the supply portion of the supply rack has been described, but the present invention is not limited to this. The component container for containing the components to be supplied in the predetermined period from the present time (for example, the components that may be supplied in the present day) may be moved to the supply unit, or the component container for containing the components that may be supplied at the timing of "next" other than "next (next)".

The order of execution of the steps in the flowchart is an example shown for the purpose of specifically explaining the present disclosure, and may be other than the above. Further, a part of the above steps may be performed simultaneously (in parallel) with other steps, or a part of the above steps may not be performed.

The division of the functional blocks in the block diagrams is an example, and a plurality of functional blocks may be realized as one functional block, or one functional block may be divided into a plurality of functional blocks, or a part of the functions may be transferred to other functional blocks. Also, the functions of a plurality of functional blocks having similar functions may be processed in parallel or time-division by a single hardware or software.

In the above embodiments, the processing unit may be configured by dedicated hardware, or may be implemented by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or a processor, or by reading and executing a software program recorded in a recording medium such as a hard disk or a semiconductor memory.

Furthermore, an aspect of the present disclosure may be a computer program for causing a computer to execute the steps having features included in the supply method shown in any one of fig. 7, 8, 10, and 12.

Further, the program may be a program for causing a computer to execute, for example. Further, an aspect of the present disclosure is a non-transitory recording medium readable by a computer having the program recorded thereon. For example, the above-described program may be distributed or circulated in a recording medium. For example, the distributed program may be installed in a device having another processor, and the processor may execute the program, thereby enabling the device to perform the above-described processes.

The present disclosure relates to a rack for temporarily storing components, for supplying component containers to a manufacturing apparatus, and the like.
