Summary of the Invention
Problems to be Solved by the Invention
[0004] Incidentally, in order to transport or store multiple feeders at once, it is conceivable to use a feeder magazine that accommodates the multiple feeders, or to incorporate a structure equivalent to such a feeder magazine into a mounting machine or the like. By providing grooves on both the top and bottom of such a feeder magazine, it would be possible to stably support multiple feeders. However, in this case, it is not always easy to correctly set the feeders in the grooves on the top and the corresponding grooves on the bottom, which would worsen the workability when storing the feeders in the feeder magazine. Furthermore, if the lower end of a feeder gets stuck in a groove on the bottom that does not correspond to a groove on the top, there is a risk that the feeder may bend significantly or interfere with other feeders and be damaged.
[0005] Therefore, the primary objective of this disclosure is to provide a feeder magazine and a component mounting machine that ensure good workability when housing feeders and can stably house multiple feeders. [Means for solving the problem]
[0006] The feeder magazine of this disclosure includes a top, bottom, back, and an opening opposite the back, and houses a plurality of feeders, each holding a plurality of components, and includes a plurality of support grooves formed in the top, each opening on the bottom side and extending parallel to each other from the opening toward the back, into which the upper end of each feeder is inserted and detachably; a plane formed in the bottom so as to face the plurality of support grooves in the top; and a plurality of positioning parts disposed in the bottom so as to correspond to each of the plurality of support grooves on the opening side of the plane, and engaging with engaging parts formed on the lower end of each feeder as the feeder is pushed toward the back from the opening with its upper end inserted into the support groove.
[0007] When a feeder is placed in the feeder magazine of this disclosure, the upper end of the feeder is inserted into the corresponding support groove on the ceiling, and the feeder is pushed in from the opening toward the rear. As the feeder is pushed in from the opening toward the rear, the engaging portion of the feeder engages with the positioning portion on the opening side, and the placement of the feeder into the feeder magazine is completed. In essence, by supporting the feeder in the support groove on the ceiling and pushing it toward the rear, it is possible to place the feeder into the feeder magazine. Furthermore, even if the engaging portion of the feeder engages with at least one of the positioning portions that does not correspond to the support groove supporting the upper end, the engaging portion of the feeder can be re-engaged with the positioning portion corresponding to the support groove supporting the upper end without removing the entire feeder from the feeder magazine. Therefore, it is possible to place multiple feeders in the feeder magazine so that they extend straight in the vertical direction without tilting them. Furthermore, since foreign matter is less likely to accumulate on the bottom surface, foreign matter is prevented from getting caught between the lower end of the feeder and the surface, thereby effectively suppressing tilting of the feeder and interference with other feeders caused by foreign matter getting caught. As a result, the feeder magazine of this disclosure ensures good workability when housing feeders and makes it possible to stably house multiple feeders.
[0008] The component mounting machine of this disclosure has a feeder mounting section that accommodates a plurality of feeders, each holding a plurality of components, and is a component mounting machine that picks up the components from the feeders and mounts them on an object, wherein the feeder mounting section includes a top section, a bottom section, a back section, an opening on the opposite side of the back section, a plurality of support grooves formed in the top section that open on the bottom section side and extend parallel to each other from the opening toward the back section, into which the upper ends of the feeders are inserted and removed, a plane formed in the bottom section opposite to the plurality of support grooves in the top section, and a plurality of positioning parts disposed in the bottom section on the opening side of the plane so as to correspond to each of the plurality of support grooves, and which engage with engagement parts formed in the lower ends of the feeders as the feeders are pushed toward the back section from the opening with their upper ends inserted into the support grooves. With such a component mounting machine, it is possible to ensure good workability when housing the feeders in the feeder mounting section and to stably house a plurality of feeders.

[0010] Next, with reference to the drawings, embodiments for carrying out the invention of this disclosure will be described.
[0011] Figure 1 is a schematic diagram showing a production line 1 utilizing the feeder magazine 100 of this disclosure. The production line 1 shown in the figure produces substrates S on which components P are mounted, and includes a printing device 2, a printing inspection device 3, a storage unit (buffer station) 4, a plurality of component mounting machines 5 (for example, four in this embodiment), a mounting inspection device 6, a reflow device 7, a reflow inspection device 8, a line control device 10, etc. The printing device 2, the printing inspection device 3, the storage unit 4, the plurality of component mounting machines 5, the mounting inspection device 6, the reflow device 7, and the reflow inspection device 8 are arranged in this order along a predetermined transport direction of the substrates S.
[0012] The printing apparatus 2 prints solder onto the wiring pattern of the substrate S and includes a substrate transport device for transporting the substrate S, a print head, a head moving device for moving the print head, a fixed frame to which a screen mask is fixed, a control device which is a computer including a CPU, ROM, RAM, non-volatile storage device, input / output interface, etc. (all not shown). The printing inspection apparatus 3 inspects the condition of the solder printed on the substrate S by the printing apparatus 2 and includes an inspection mechanism and a control device (computer) that controls the inspection mechanism. The control devices of the printing apparatus 2 and the printing inspection apparatus 3 exchange information with the line control device 10 via wireless or wired communication, respectively.
[0013] In this embodiment, the storage unit 4 is incorporated between the printing inspection device 3 and the upstream component mounting machine 5 of the production line 1, and includes a plurality of (two in this embodiment) storage spaces 41 and a plurality of (two in this embodiment) electric conveyors 42 installed in the corresponding storage spaces 41 to transfer items to and from the electric conveyors 91 of the automated guided vehicles (AGVs) 90. In this embodiment, the line control device 10 of the production line 1 is installed in the storage unit 4 and controls the controlled objects such as the electric conveyors 42 of the storage unit 4. Multiple items used in the production of substrates S with components P mounted are temporarily stored in the storage unit 4 in order to improve the production efficiency of the production line 1.
[0014] In this embodiment, the items stored in the storage unit 4 are feeders 50 that are attached to each component mounting machine 5. Multiple feeders 50 that are scheduled to be attached to the component mounting machine 5 (before use) are stored in one storage space 41, and multiple used feeders 50 that have been removed from the component mounting machine 5 are stored in the other storage space 41. In this embodiment, a box-shaped feeder magazine 100 capable of accommodating multiple feeders 50 is used to transfer multiple feeders 50 at once between the storage unit 4 and the automated guided vehicle 90. Note that the multiple feeders 50 stored in one feeder magazine 100 may contain different components or the same components.
[0015] Furthermore, production line 1 includes a loader 9. The loader 9 is controlled by the line control device 10 to move along the transport direction of the substrate S and to transfer feeders 50 between the storage unit 4 and the multiple component mounting machines 5. That is, the loader 9 collects the used feeders 50 from the corresponding component mounting machines 5 and stores them in the feeder magazine 100 stored in the other storage space 41 of the storage unit 4. The loader 9 also takes out the unused feeders 50 from the other storage space 41 (feeder magazine 100) of the storage unit 4 and mounts them in the corresponding component mounting machines 5.
[0016] The plurality of component mounting machines 5 are all surface mounting machines that can pick up components P from a tape fed out by a feeder 50 and mount them on a substrate S as an object, and as shown in FIG. 1, they are arranged along the conveyance direction of the substrate S on the downstream side of the printing inspection apparatus 3. Each component mounting machine 5 includes a housing, a feeder set table on which a plurality of feeders 50 are mounted, a substrate conveyance device, an XY moving device, a mounting head including at least one suction nozzle, a parts camera, a mark camera, a nozzle station (all not shown), and a control device 5c, etc. The control device 5c of each component mounting machine 5 is a computer including a CPU, ROM, RAM, a non-volatile storage device, an input / output interface, etc., and exchanges information with the line control device 10 via wireless or wired communication.
[0017] Also, the control device 5c acquires imaging data of the parts camera and the mark camera, detection values of various sensors (not shown) installed in the substrate conveyance device, the XY moving device, the mounting head, etc. Further, the control device 5c executes a production program based on information from the line control device 10, imaging data of the parts camera and the mark camera, detection values of various sensors, etc., and controls a plurality of feeders 50 (component supply units), the substrate conveyance device, the XY moving device, the mounting head, etc. The production program defines the mounting order of the components P on the substrate S in the plurality of component mounting machines 5 of the production line 1, the production quantity of the substrate S, etc., and is stored in the ROM, etc. of the control device 5c.
[0018] The mounting inspection device 6 inspects the mounting status of components P mounted by each component mounting machine 5, and includes an inspection mechanism and a control device (computer) that controls the inspection mechanism. The control device of the mounting inspection device 6 also exchanges information with the line control device 10 via wireless or wired communication. The reflow apparatus 7 is located downstream of the mounting inspection device 6 and includes a substrate transport device that transports substrates S from the mounting inspection device 6, a heating unit that heats the substrates S transported by the substrate transport device, and a control device that controls the substrate transport device, heating unit, etc. The reflow apparatus 7 melts the solder on the substrate S by heating the substrate S to a predetermined reflow temperature (e.g., 220°C-250°C) in the heating unit. As a result, the molten solder cools and solidifies, electrically connecting and fixing each component to the wiring pattern on the substrate S. The reflow inspection device 8 inspects the state of components P on the substrate S that has undergone reflow processing, and includes an inspection mechanism and a control device that controls the inspection mechanism. The control devices for the reflow apparatus 7 and the reflow inspection apparatus 8 are both computers that include a CPU, ROM, RAM, storage device, etc., and they exchange information with the line control device 10 via wireless or wired communication.
[0019] The line control device 10 is a computer that includes a CPU, ROM, RAM, non-volatile storage devices such as hard disk drives or solid-state drives, and input / output interfaces, as well as input devices such as a keyboard and mouse, and display devices (not shown in the illustration) to which these are connected. The storage device of the line control device 10 stores various production information related to the production of the substrate S. The production information includes the inventory status and supply status of components P to be mounted on the substrate S, the production plan for the substrate S (including the usage plan for components P), the production status of the substrate S, and the operating status of multiple component mounting machines 5 that constitute the production line 1. The line control device 10 also provides various command signals to the printing control unit of the printing device 2, the control devices 5c of each component mounting machine 5, the reflow control unit of the reflow device 7, etc., in response to requests from the equipment side. The line control device 10 may also be composed of a server and terminals connected to the server via a network.
[0020] The feeder 50 mounted on each component mounter 5 of the production line 1 is a cassette-type tape feeder. As shown in FIG. 2, it includes a tape reel 51 around which a tape containing a plurality of components P is wound, and a thin box-shaped feeder body 52 that removably houses the tape reel 51. In the tape reel 51, the plurality of components P are each protected by a film covering the surface of the tape, and the film is peeled off before the component P reaches the component supply position in the component mounter 5. Further, inside the feeder body 52, a tape feeding mechanism for pulling out the tape from the tape reel 51 and feeding it to the component supply position, and a feeder control device for controlling the tape feeding mechanism are housed (both are not shown). The feeder control device includes a microcomputer having a CPU, ROM, RAM, etc. In the present embodiment, electrical components such as the tape feeding mechanism and the feeder control device are housed in an electrical component housing portion 52e defined between the front end face 52f located on the right side of the feeder body 52 in FIG. 2 and the housing portion of the tape reel 51.
[0021] Also, the front end face 52f of the feeder body 52 extends vertically above the center in the height direction of the feeder body 52 and orthogonal to the upper end face of the feeder body 52, and is inclined so as to approach the rear end face 52r of the feeder body 52 located on the left side in FIG. 2 as it goes downward from near the center. And on the upper part 52u of the front end face 52f located above the center in the height direction of the feeder body 52, first and second positioning pins 53a and 53b are provided. The first positioning pin 53a projects from the upper part 52u of the front end face 52f near the upper end face of the feeder body 52 to the right side in FIG. 2, and the second positioning pin 53b projects from the upper part 52u of the front end face 52f to the right side in FIG. 2 below the first positioning pin 53a. In the present embodiment, the tip of the lower second positioning pin 53b is located on the rear end face 52r side (left side in FIG. 2) of the tip of the upper first positioning pin 53a.
[0022] Furthermore, a feeder connector 54 is installed on the upper part 52u of the front end surface 52f. The feeder connector 54 protrudes to the right in Figure 2 from between the first and second positioning pins 53a and 53b, which are spaced apart in the vertical direction. When the feeder 50 is mounted on the component mounting machine 5 and the feeder connector 54 is connected to a connector (not shown) provided on the component mounting machine 5, power is supplied from the component mounting machine 5 to electrical components such as the tape feeding mechanism and the feeder control device, and various information is exchanged between the control device 5c (see Figure 1) of the component mounting machine 5 and the feeder control device. In addition, the feeder body 52 includes a bumper 52a that protrudes to the right in Figure 2 from between the upper part 52u of the front end surface 52f and the downward inclined portion.
[0023] Furthermore, a relatively long guide rail 55 having a T-shaped cross-section is fixed to the upper end surface of the feeder body 52. The guide rail 55 extends from near the rear end of the electrical component housing section 52e of the feeder body 52 to just before the rear end surface 52r, forming the upper end of the feeder 50. In addition, the feeder body 52 includes a clamp member 56a for fixing the feeder 50 to the component mounting machine 5 and the feeder magazine 100. The clamp member 56a is biased by a biasing member such as a spring (not shown) so as to protrude diagonally upward from the upper end surface of the feeder body 52 toward the rear end surface 52r on the side of the rear end surface 52r of the guide rail 55, and engages with an engaged portion formed on the component mounting machine 5 and the feeder magazine 100. Furthermore, by operating a release lever 56b protruding from the rear end surface 52r of the feeder body 52, the clamp member 56a can be moved against the biasing force of the biasing member, and the engagement between the clamp member 56a and the engaged portion can be released.
[0024] In addition, a relatively long rail member 57, which forms the lower end surface of the feeder 50, is fixed to the lower end of the feeder body 52. The front end 57t of the rail member 57 is located on the rear end surface 52r side of the first and second positioning pins 53a, 53b and the upper part 52u of the front end surface 52f, and the rail member 57 extends from near the rear end of the electrical component housing 52e of the feeder body 52 to just before the rear end surface 52r. Furthermore, a projection 57p is formed on the lower end of the feeder body 52, which protrudes downward from the lower end surface of the rail member 57 (feeder 50) on the rear end surface 52r side of the rail member 57.
[0025] Figure 3 is a perspective view showing the feeder magazine 100 of the present disclosure. As shown in the figure, the feeder magazine 100 includes a top portion 110, a bottom portion 120, a pair (two) side portions 130 connecting the corresponding side edges of the top portion 110 and the bottom portion 120, and a back portion 140 connecting the side edges of the pair of side portions 130. The top portion 110, the bottom portion 120, and the pair of side portions 130 define an opening 150 located on the opposite side of the back portion 140.
[0026] As shown in Figure 3, the top portion 110 of the feeder magazine 100 is formed to cover a predetermined area on the side of the opening 150 of the bottom portion 120, and an opening is formed between the top portion 110 and the back portion 140. Furthermore, the top portion 110 has a plurality of slots 111 (support grooves) (65 in this embodiment) into which the guide rails 55 (upper ends) of the feeder 50 are inserted and removed. As shown in Figure 4, each of the plurality of slots 111 has a T-shaped cross-section, opens on the bottom portion 120 side (lower side), and extends parallel to each other from the opening 150 toward the back portion 140 (see Figure 3). As a result, when the guide rails 55 of the feeder 50 are inserted into the slots 111, the feeder 50 is supported in a suspended state by the top portion 110 via the guide rails 55 inserted into the slots 111.
[0027] As shown in Figure 3, the bottom 120 of the feeder magazine 100 includes a flat surface 12s without irregularities (grooves), a plurality of (for example, 65 in this embodiment) first positioning portions 121 that can engage with projections 57p (engaging portions) formed at the lower end of the feeder 50, and a plurality of (for example, 65 in this embodiment) second positioning portions 122 that can engage with the front end 57t (second engaging portion) of the rail member 57 provided at the lower end of the feeder 50. The flat surface 12s is a smooth, flat surface formed on the surface (upper surface) of the bottom 120 so as to extend parallel to the ceiling portion 110 and face the plurality of slots 111.
[0028] Each of the multiple first positioning portions 121 is positioned on the bottom portion 120 so as to correspond to each of the multiple slots 111 of the ceiling portion 110 on the side of the opening 150 of the plane 12s, as shown in Figure 3. More specifically, each of the multiple first positioning portions 121 is a recessed area from the plane 12s that opens on the side of the opening 150, and as shown in Figure 4, it faces the corresponding slot 111 in the vertical direction when viewed from the side of the opening 150. In this embodiment, the multiple first positioning portions 121 are formed at equal intervals along the longitudinal direction on the thin-walled edge of a plate member 123 having a substantially wedge-shaped cross-section that becomes thinner from one edge extending in the longitudinal direction to the other edge. The plate member 123 is fixed to the bottom portion 120 so as to be flush with the plane 12s and continuous on the thick-walled back portion 140 side.
[0029] As shown in Figure 3, the multiple second positioning sections 122 are composed of multiple projections 125 formed on a narrow plate member 124. In this embodiment, the multiple projections 125 are formed along the longitudinal direction of the plate member 124 at intervals (equal intervals) corresponding to the groove width of the slot 111 and the width of the rail member 57 (front end 57t), and each projection protrudes upward from the surface of the plate member 124. The plate member 124 is fixed to the bottom 120 such that each projection 125 extends parallel to the slot 111 of the ceiling section 110, and the surfaces between adjacent projections 125 are flush with the plane 12s on the back side 140 of the plane 12s. Once the plate member 124 is fixed to the bottom 120, as shown in Figure 3, the multiple projections 125 are arranged on the bottom 120 so as to correspond to each of the multiple slots 111 of the ceiling section 110 on the back side 140 of the plane 12s. In other words, as shown in Figure 4, the space between two adjacent protrusions 125 faces the corresponding slot 111 in the vertical direction when viewed from the opening 150 side, and forms a second positioning portion 122 that can engage with the front end 57t of the rail member 57.
[0030] As shown in Figures 3 and 4, the back portion 140 of the feeder magazine 100 includes a plurality of (65 in this embodiment) first positioning holes 143a into which the first positioning pins 53a of the feeder 50 are inserted, and a plurality of (65 in this embodiment) second positioning holes 143b into which the second positioning pins 53b of the feeder 50 are inserted. The plurality of first positioning holes 143a are formed in the back portion 140 at intervals (equally spaced) along the upper edge of the back portion 140 so as to correspond to each of the plurality of slots 111 of the ceiling portion 110. The plurality of second positioning holes 143b are formed in the back portion 140 at intervals below each of the first positioning holes 143a so as to correspond to each of the plurality of slots 111 of the ceiling portion 110.
[0031] Furthermore, the back section 140 includes a plurality of connectors 144 (for example, 65 in this embodiment) that can each be connected to the feeder connector 54 of the feeder 50. As shown in Figure 4, the plurality of connectors 144 are fixed to the back section 140 so as to face the opening 150 side between the corresponding first and second positioning holes 143a and 143b in the vertical direction. Each of the plurality of connectors 144 is connected to an external connector (not shown) fixed to the back section 140, and this external connector can be connected to a connector (not shown) provided in the storage space 41 of the storage unit 4. As a result, each feeder 50 can be connected to the line control device 10 and the power supply of the storage unit 4 (not shown) via the feeder connector 54, connectors 144, external connector, etc., and feeder information from each feeder 50 can be taken into the line control device 10.
[0032] In addition, as shown in Figures 3 and 4, a recess 145 is formed in the back portion 140 to receive the bumper 52a of the feeder 50. In this embodiment, the feeder mounting portion 5f (see Figure 1) of each component mounting machine 5 is capable of accommodating multiple feeders 50, and the feeder mounting portion 5f includes the slots corresponding to the ceiling portion 110, bottom portion 120, a pair of side portions 130, slot 111, first and second positioning portions 121, 122, first and second positioning holes 143a, 143b, connector 144, recess 145, etc.
[0033] When a user (person) manually places a feeder 50 into the feeder magazine 100 configured as described above, first, the front part of the feeder 50 is inserted into the feeder magazine 100 through the opening 150, and the guide rail 55 (upper end) of the feeder 50 is inserted into the target slot 111 in the ceiling part 110, as shown in Figure 5. Furthermore, with the guide rail 55 inserted into the slot 111, the feeder 50 is pushed in from the opening 150 toward the back part 140. At this time, the bumper 52a of the feeder 50 appropriately pushes aside other feeders 50 already housed in the feeder magazine 100. As shown in Figure 6, as the feeder 50 is pushed toward the back part 140, the first positioning pin 53a of the feeder 50 reaches the entrance of the first positioning hole 143a in the back part 140. Furthermore, as the feeder 50 moves further toward the back portion 140, the first positioning pin 53a is inserted into the first positioning hole 143a, and the second positioning pin 53b of the feeder 50 reaches the entrance of the second positioning hole 143b of the back portion 140.
[0034] In this embodiment, the feeder 50 and feeder magazine 100 are configured such that, as shown in Figure 7, when the second positioning pin 53b reaches the entrance of the second positioning hole 143b, the distance L1 between the projection 57p (engaging portion) and the engagement start position of the first positioning portion 121 becomes shorter than the distance L2 from the front end 57t (second engaging portion) of the rail member 57 to the two protruding pieces 125 that constitute the first positioning portion 121. As a result, as the feeder 50 moves, the second positioning pin 53b is inserted into the second positioning hole 143b, and as shown in Figure 8, the projection 57p of the feeder 50 enters into the first positioning portion 121 (recess) corresponding to the slot 111 supporting the guide rail 55 and engages with the first positioning portion 121.
[0035] As the feeder 50 is pushed further toward the rear 140, as can be seen in Figure 9, the front end 57t (second engagement portion) of the rail member 57 engages with the second positioning portion 122 corresponding to the slot 111 supporting the guide rail 55. That is, the front end 57t of the rail member 57 is held from both sides by the two protrusions 125 that constitute the second positioning portion 122. Also, as shown in Figures 8 and 9, the feeder connector 54 of the feeder 50 connects with the connector 144 corresponding to the slot 111 supporting the guide rail 55 as the feeder 50 moves toward the rear 140. Furthermore, the clamp member 56a of the feeder 50 engages with an engagement portion (not shown) formed on the feeder magazine 100. This restricts the movement of the feeder 50 toward the rear 140, and the storage of one feeder 50 into the feeder magazine 100 is completed.
[0036] As explained above, when installing the feeder 50 into the feeder magazine 100, the guide rail 55 forming the upper end of the feeder 50 is inserted into the target slot 111 in the ceiling portion 110, and the feeder 50 is pushed in from the opening 150 toward the back portion 140. As the feeder 50 is pushed in from the opening 150 toward the back portion 140, the projection 57p (engaging portion) of the feeder 50 and the front end 57t (second engaging portion) of the rail member 57 engage with the first positioning portion 121 on the opening 150 side or the second positioning portion 122 on the back portion 140 side, completing the installation of the feeder 50 into the feeder magazine 100. In short, by supporting the feeder 50 in the slot 111 of the ceiling portion 110 and pushing it toward the back portion 140, it is possible to install the feeder 50 into the feeder magazine 100.
[0037] Furthermore, in the feeder magazine 100, the multiple first positioning parts 121 are arranged on the side of the opening 150 of the plane 12s, and the multiple second positioning parts 122 are arranged on the side of the back 140 of the plane 12s. As a result, even if at least one of the projections 57p and front end 57t of the feeder 50 engages with at least one of the first and second positioning parts 121, 122 that do not correspond to the slots 111 that support the guide rails 55, the projections 57p and front end 57t of the feeder 50 can be re-engaged with the first and second positioning parts 121, 122 that correspond to the slots 111 that support the guide rails 55 without removing the entire feeder 50 from the feeder magazine 100. Therefore, it is possible to house multiple feeders 50 in the feeder magazine 100 so that they extend straight in the vertical direction without tilting them. Furthermore, in the feeder magazine 100, foreign matter is less likely to accumulate on the flat surface 12s of the bottom 120, preventing foreign matter from getting caught between the lower end of the feeder 50 and the flat surface 12s, thereby effectively suppressing tilting of the feeder 50 and interference with other feeders 50 caused by foreign matter getting caught. As a result, the feeder magazine 100 ensures good workability when storing the feeders 50 and makes it possible to stably store multiple feeders 50.
[0038] Furthermore, the feeder 50 has a first positioning pin 53a that protrudes toward the back 140 from the upper part 52u of the front end face 52f, which is the end face on the back 140 side, and a second positioning pin 53b that protrudes toward the back 140 from the upper part 52u of the front end face 52f, below the first positioning pin 53a. In the above embodiment, the tip of the second positioning pin 53b is located closer to the opening 150 than the tip of the first positioning pin 53a. In addition, the back 140 is formed with a plurality of first positioning holes 143a into which the first positioning pin 53a of the feeder 50 is inserted, and a plurality of second positioning holes 143b into which the second positioning pin 53b of the feeder 50 is inserted, corresponding to each of the plurality of slots 111.
[0039] As a result, when the feeder 50 is pushed in from the opening 150 toward the back portion 140, the first positioning pin 53a is inserted into the first positioning hole 143a of the back portion 140, and then the second positioning pin 53b is inserted into the second positioning hole 143b. This allows the feeder 50, supported by the slot 111 of the ceiling portion 110, to extend straight in the vertical direction by the first and second positioning pins 53b, and enables the projection 57p or front end 57t of the feeder 50 to smoothly engage with the first and second positioning portions 121 and 122 corresponding to the slot 111 that supports the guide rail 55.
[0040] Furthermore, in the above embodiment, as the feeder 50 is pushed from the opening 150 toward the back 140, the second positioning pin 53b reaches the second positioning hole 143b, after which the projection 57p (engaging portion) of the feeder 50 engages with the first positioning portion 121, and thereafter the front end 57t (second engaging portion) of the rail member 57 of the feeder 50 engages with the second positioning portion 122. In other words, in the above embodiment, if the projection 57p of the feeder 50 engages with the first positioning portion 121 which does not correspond to the slot 111 supporting the guide rail 55, the feeder 50 will tilt, preventing the front end 57t of the rail member 57 from smoothly engaging with the second positioning portion 122, making it difficult to push the feeder 50 toward the back 140. This makes it easy for a user attempting to place the feeder 50 into the feeder magazine 100 to notice that the projection 57p (engaging part) of the feeder 50 is not engaged with the first positioning part 121, which it should be engaged with, and prompts them to correct the issue.
[0041] Furthermore, in the above embodiment, the plane 12s of the bottom portion 120 extends parallel to the ceiling portion 110. Also, the projection 57p (engaging portion) of the feeder 50 protrudes below the lower end surface of the rail member 57 (feeder 50), and the first positioning portion 121 is a recess that is recessed from the plane 12s that opens on the opening 150 side and engages with the projection 57p of the feeder 50. Furthermore, the two projections 125 that constitute the second positioning portion 122 hold the front end 57t (the end on the back portion 140 side) of the rail member 57 of the feeder 50 from both sides. This prevents the lower end of the feeder 50 (such as the front end 57t of the rail member 57) from interfering with the first positioning part 121 when inserting the guide rail 55 of the feeder 50 into the slot 111 of the ceiling part 110. Furthermore, if the projection 57p is engaged with the first positioning part 121 (recess) that does not correspond to the slot 111 that supports the guide rail 55 of the feeder 50, it becomes possible to easily and quickly disengage the projection 57p from the first positioning part 121 and engage it with the first positioning part 121 that it should be engaged with.
[0042] Furthermore, the feeder 50 includes a guide rail 55 having a T-shaped cross-section fixed to the upper end surface of the feeder body 52, and is supported suspended by the ceiling portion 110 via the guide rail 55 inserted into the slot 111. This allows the feeder 50 to extend straight in the vertical direction by its own weight until the projection 57p of the feeder 50 and the front end 57t of the rail member 57, which are pushed toward the back portion 140, engage with the first or second positioning portions 121, 122.
[0043] Up to this point, the feeder magazine 100 of this disclosure has been described using the example of manually loading the feeder 50 into the feeder magazine 100, but it goes without saying that the feeder 50 can also be loaded into the feeder magazine 100 by a transport device such as a loader 9. Furthermore, the feeder 50 may be configured such that the tip of the first positioning pin 53a is located closer to the opening 150 than the tip of the second positioning pin 53b. Moreover, if the feeder 50 has relatively high rigidity, for example, the feeder 50 and the feeder magazine 100 may be configured such that the projection 57p (engaging portion) of the feeder 50 and the front end 57t (second engaging portion) of the rail member 57 engage with the first or second positioning portions 121, 122 simultaneously. Furthermore, the flat surface 12s of the bottom 120 of the feeder magazine 100 does not necessarily have to be a flat surface extending parallel to the top 110. It may be a sloped surface or a gently curved surface as long as it is a surface without irregularities (slots), or it may be a flat surface with minute irregularities that do not substantially accumulate foreign matter, such as those formed by the attachment of seals or the fixing of wiring, and holes may be formed in the flat surface 12s.
[0044] Furthermore, by providing multiple second positioning parts 122 (multiple protrusions 125) on the feeder magazine 100, or by providing elements equivalent to multiple second positioning parts 122 (multiple protrusions 125) on the feeder mounting part 5f of the component mounting machine 5, it becomes possible to support multiple feeders 50 very stably with the feeder magazine 100, etc., but it is not limited to this. That is, the multiple second positioning parts 122 (multiple protrusions 125) may be omitted from the feeder magazine 100, and elements equivalent to multiple second positioning parts 122 (multiple protrusions 125) may be omitted from the feeder mounting part 5f of the component mounting machine 5. In such a feeder magazine 100, etc., basically, if the feeder 50 is supported in the slot 111 of the ceiling part 110 and pushed toward the back part 140, it becomes possible to accommodate the feeder 50 in the feeder magazine 100. Furthermore, even if the projection 57p of the feeder 50 engages with the first positioning part 121 that does not correspond to the slot 111 supporting the guide rail 55, the projection 57p can be re-engaged with the first positioning part 121 that corresponds to the slot 111 supporting the guide rail 55 without removing the entire feeder 50 from the feeder magazine 100. Therefore, in this embodiment as well, it is possible to house multiple feeders 50 in the feeder magazine 100 or feeder mounting part 5f so that they extend straight in the vertical direction without tilting, thereby ensuring good workability when housing the feeders 50 and stably housing multiple feeders 50.
