Description
[Technical Field]
[0001] The present disclosure relates to a component stock device and a component mounting system. [Background technology]
[0002] A parts conveying device capable of appropriately managing parts is known (see, for example, Patent Document 1). This parts conveying device includes a mounting unit on which a tray for supporting parts is mounted, a cart having wheels that can contact a running surface, and an automated guided vehicle that is connected to the cart via a connecting mechanism so as to be relatively movable and that travels on the running surface.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-91770 Summary of the Invention [Problem to be solved by the invention]
[0004] However, in recent years, the frequency of electronic component replenishment during production in the surface mounting technology (SMT) process has increased as equipment productivity has improved, creating a greater demand for labor-saving and automated component replenishment. This is partly due to the increasing size of components, such as automotive connectors, and the adoption of SMT for large components in downstream processes, which has led to larger tray components. This has reduced the number of components that can be supplied per tray, resulting in an increased frequency of component replenishment. To address this issue, labor savings in component replenishment require an increased component load, but from the perspective of area productivity, simply expanding the space of the component mounting equipment is not feasible. For example, automatic magazine transfer requires the magazine to be fully extended from the stocker unit that handles the magazine transfer. This requires a drive source (e.g., an air cylinder) to provide a large stroke for the magazine drive unit located within the stocker unit. As a result, the drive source becomes large (i.e., long), making it difficult to miniaturize the equipment that houses the drive source. Against this backdrop, there is a demand for automated magazine transfer and for improving area productivity by arranging more equipment in a limited space.
[0005] The present disclosure has been devised in consideration of the above-described conventional situation, and aims to provide a component stock device and a component mounting system that facilitates the transfer of magazines using compact equipment, enables labor savings in pallet supply, and increases area productivity. [Means for solving the problem]

[0012] Hereinafter, with reference to the drawings as appropriate, a detailed description of an embodiment of a component stock device and a component mounting system according to the present disclosure will be provided. However, unnecessary detailed description may be omitted. For example, detailed description of well-known matters or redundant description of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure and are not intended to limit the subject matter recited in the claims.
[0013] 1 is a plan view of a factory floor where a component mounting system 11 according to embodiment 1 is installed. In the following drawings with arrows indicating directions, the X axis indicates the left-right direction of the component mounting device 13, the Y axis indicates the front-rear direction of the component mounting device 13, and the Z axis indicates the up-down direction of the component mounting device 13. The X axis and Y axis are orthogonal to each other and are contained in a horizontal plane. The Z axis is contained in a vertical plane that is orthogonal to the horizontal plane.
[0014] 1, a plurality of component mounting devices 13 are arranged closely next to each other along an aisle 15 having an aisle width W1 on the factory floor. Each component mounting device 13 is provided with a plurality of parallel board transport conveyors 19, with the X-axis direction being the transport direction of the boards 17, extending between the plurality of component mounting devices 13. A stick feeder 21, a tray component supply device 23, or a tape component supply device 25 is integrally connected to the component mounting device 13.
[0015] A plurality of component mounting devices 13 arranged side by side constitute a mounting line 27 on a factory floor. In particular, on factory floors with high production volumes, a plurality of mounting lines 27 are installed in parallel, separated by an aisle 15 in the direction along the X-axis that passes in front of and behind the component mounting devices 13. Of the plurality of component mounting devices 13 arranged side by side, a component mounting device 13 in which a tray component stock device 29 is integrally connected to a tray component supply device 23 constitutes a component mounting system 11.
[0016] In the component mounting system 11, the tray component stock device 29 is installed such that its longitudinal direction is aligned with the passage 15, so that the reduction rate of the effective passage width W2 between adjacent mounting lines 27 is kept to a minimum.
[0017] Fig. 2 is an overall configuration diagram of the component mounting system 11 shown in Fig. 1. The component mounting system 11 according to the first embodiment includes a component mounting device 13 that picks up components 33 (see Fig. 4) stored in trays 31 (see Fig. 4) using a mounting head 35 (see Fig. 3) that is a component mounting unit and mounts them on a board 17, a tray component supply device 23 that supplies the trays 31 to a position where the trays 31 can be picked up by the mounting head 35, and a tray component stock device 29 that replenishes the tray component supply device 23 with trays 31.
[0018] The component mounting device 13 has a component mounting device main body 37. The component mounting device main body 37 has a passage-side surface to which the tray component supply device 23 and the tape component supply device 25 are connected. The component mounting device main body 37 is integrally connected to the tray component stock device 29 via the tray component supply device 23.
[0019] The tray components stock device 29, an example of a components stock device, includes a magazine 41 that allows a pallet 39 (see FIG. 4) on which a tray 31 storing components 33 (see FIG. 4) is placed to be inserted and removed along a first axis (e.g., the X-axis). The tray components stock device 29 includes a pallet stock unit 43 that functions as a stocker. The pallet stock unit 43 allows the magazine 41 to be inserted and removed along a second axis (e.g., the Y-axis) that intersects with the X-axis within a horizontal plane. The tray components stock device 29 also includes a pallet transport unit 45. The pallet transport unit 45 transports a pallet 39 along the X-axis from the magazine 41 stored in the pallet stock unit 43. The pallet 39 transported from the pallet stock unit 43 by the pallet transport unit 45 is supplied to the tray components supply device 23. In addition, the pallet transport section 45 transports pallets 39 from the tray component supply device 23 to the pallet stock section 43 for collection when the pallets 39 have consumed components 33 (i.e., all components 33 on the pallet 39 have been used to mount on the board 17).
[0020] Fig. 3 is a conceptual diagram showing the cross-sectional structure of the component mounting system 11 shown in Fig. 2. The component mounting device main body 37 is provided with a board transport section 49 on the upper surface of a base 47, the board transport section 49 having a board transport conveyor 19 for transporting the board 17 in a direction along the X-axis (board transport direction). The board transport section 49 transports the board 17 on which components are to be mounted, and positions and holds it at the working position of the component mounting device main body 37. A tray component supply device 23 is arranged on the aisle side of the base 47.
[0021] The tray component supply device 23 has a replacement pallet storage unit 51. The replacement pallet storage unit 51 holds multiple magazines 41 arranged in a vertical direction (along the Z axis). In the tray component supply device 23, a pallet changer 53 is provided between the replacement pallet storage unit 51 and the base 47. The pallet changer 53 raises and lowers a changer lifting table 55 using a pallet changer lifting unit 57 (see FIG. 11). The tray component supply device 23 moves the pallet 39 between the replacement pallet storage unit 51 and the component removal position by operating the pallet changer 53. The tray component supply device 23 supplies the components 33 to the mounting head 35 by moving the pallet 39, which holds the trays 31 on which the components 33 (see FIG. 4) are stored in a grid-like arrangement, to the component removal position.
[0022] The mounting head 35 is a multiple-head arrangement equipped with multiple unit transfer heads, each of which has a replaceable suction nozzle attached to its lower end. The mounting head 35 is attached so that it can move freely in the X and Y directions by an XY table 59 that moves along the Y axis and is comprised of a linear drive mechanism or the like. The XY table 59 allows the mounting head 35 to move freely between a component removal position and a component mounting position on the board transport section 49.
[0023] The tray component stock device 29 has a pallet stock section 43 and a pallet conveying section 45. The pallet stock section 43 stores a plurality of magazines 41 at predetermined intervals in the vertical direction (along the Z axis). Any pallet 39 can be inserted or removed from each magazine 41 stored in the vertical direction (along the Z axis) by the pallet conveying section 45 in the direction along the X axis. The pallet 39 pulled out from the pallet stock section 43 by the pallet conveying section 45 is moved to the tray component supply device 23 by the pallet conveying section 45. The pallet conveying section 45 can also move the pallet 39 in the opposite direction.
[0024] Fig. 4 is a perspective view of a pallet 39 on which trays 31 are placed. Fig. 5 is an exploded perspective view of the pallet 39 shown in Fig. 4.
[0025] The pallet 39 will now be described. The pallet 39 has a pallet body 61 formed in the shape of a rectangular plate in a plan view. One of a pair of parallel long sides of the pallet 39 is a first long side 63 and the other is a second long side 65. In the first embodiment, the first long side 63 is the front of the pallet, and the second long side 65 is the rear of the pallet. The pallet 39 is transported with either the first long side 63 or the second long side 65 at the leading edge in the transport direction.
[0026] Pallet 39 is made of a magnetic material at least in its upper surface. Tray 31, made of a non-magnetic material such as resin, is placed on the upper surface of pallet 39. A plurality of components 33 are aligned on tray 31. Tray 31 is held in a predetermined position on pallet 39 by a positioning device 67. Pallet 39 with tray 31 placed thereon constitutes component storage unit 69. Note that component storage unit 69 may also be a pallet 39 on which components are placed and stored. Alternatively, tray 31 may have the same external shape as pallet 39 and be used as component storage unit 69.
[0027] Two tray positioning pieces 71 are fixed to the top surface of the pallet 39, parallel to the first long side 63 and one of the short sides adjacent to the first long side 63, and are arranged perpendicular to each other. The two tray positioning pieces 71 are arranged in the perpendicular direction, thereby forming an inside corner. The tray 31 is positioned relative to the pallet 39 by pressing two side surfaces against the tray positioning piece 71 so that one corner coincides with the inside corner of the pallet 39.
[0028] The tray 31 positioned on the pallet in this manner is fixed to the pallet 39 by pressing a positioning device 67 against the surface opposite to the surface pressed against the tray positioning piece 71. The positioning device 67 has, for example, a magnet. The positioning device 67 is strongly fixed to the upper surface of the pallet 39 made of a magnetic material by magnetic force. This restricts the tray 31 from moving on the pallet 39 and fixes it in place. At this time, the positioning device 67 has two lever portions 73 on both ends (see FIG. 5), and each lever portion 73 is positioned above the upper surface of the pallet 39. The positioning device 67 can be easily removed from the pallet 39 by pressing these lever portions 73 toward the upper surface of the pallet 39 using the principle of leverage.
[0029] Pallet 39 is also provided with a first engagement portion 75 on the first long side 63 and a second engagement portion 77 on the second long side 65. The first engagement portion 75 and the second engagement portion 77 are arranged so that the opening sides of the engagement claws, which are U-shaped in plan view, face each other. The first engagement portion 75 has a larger gap between its engagement claws than the second engagement portion 77. In the first embodiment, the first engagement portion 75 engages with a changer engagement rod 79 (see FIG. 10) of the pallet changer 53, and the second engagement portion 77 engages with a handler engagement rod 81, which is a traction portion of the pallet conveying unit 45 shown in FIG. 10.
[0030] Fig. 6 is a perspective view of magazine 41 storing pallets 39. Fig. 7 is a perspective view of magazine 41 as seen obliquely from below.
[0031] The magazine 41 will now be described. The magazine 41 has a pair of parallel side plates 83 whose upper ends are connected by a top plate 85 and whose lower ends are connected by a bottom plate 87 (see FIG. 7), forming an inner storage space in the shape of a square tube with insertion / removal openings 89 on both sides. The magazine 41 is stored in the pallet stock section 43 with both ends along the X-axis facing open. In other words, the pair of side plates 83 are stored in the pallet stock section 43 with a distance between them in the direction along the Y-axis.
[0032] A rib 91 is provided on the inner surface of each side plate 83, with both ends extending across the insertion / removal opening 89. A pair of parallel short sides of the pallet 39 is inserted into the gap between adjacent ribs 91 in the vertical direction (along the Z axis). This allows the magazine 41 to store multiple pallets 39 in multiple stages in the vertical direction (along the Z axis) in the internal storage space (see above), and allows the pallets 39 to be inserted and removed through the insertion / removal opening 89.
[0033] 6, a pair of X alignment rollers 93 are provided on the lower outside of each side plate 83. Each of the pair of X alignment rollers 93 is rotatable around a rotation center perpendicular to the side plate 83. Furthermore, a Y alignment portion 95 is provided on the lower inside of each of the pair of side plates 83, close to the insertion / removal openings 89 on both ends. A tapered surface 97 is formed on the Y alignment portion 95, and the tapered surface 97 is formed by a slope that reduces the thickness of the side plate 83 downward.
[0034] 7, four Y alignment rollers 99 are provided on the underside of bottom plate 87. Each Y alignment roller 99 is supported by a mounting piece 101 hanging down from the underside of bottom plate 87 in a direction perpendicular to side plate 83 so as to be rotatable around a rotation center perpendicular to this mounting piece 101. The above-mentioned X alignment rollers 93 and Y alignment rollers 99 constitute a first alignment group 103.
[0035] A pair of parallel lower sides of the insertion / removal opening 89 at both ends of the bottom plate 87 form X alignment portions 105. The Y alignment portion 95 having the tapered surface 97 described above and the X alignment portion 105 form a second alignment group 107.
[0036] FIG. 8 is a perspective view of the tray components stock device 29 shown in FIG. 2. The pallet stock unit 43 has a housing (e.g., a cover 109) that forms an internal space capable of storing the magazine 41. This cover 109 has an opening (e.g., a magazine replacement window 111) that allows the magazine 41 to be inserted and removed along the second axis (Y-axis). The lower part of the magazine replacement window 111 of the pallet stock unit 43 serves as a base 113. This base 113 is provided with a docking unit 115. The docking unit 115 serves as a connection portion when, for example, a self-propelled magazine transport device (not shown) is used. The docking unit 115 is provided with a connector 117, thereby electrically connected to the tray components stock device control unit 119 (see FIG. 11). In addition, an operation unit 121, such as a touch panel, electrically connected to the tray components stock device control unit 119 (see FIG. 11) is provided on the outer surface of the pallet transport unit 45 on the aisle side. The operation unit 121 may be omitted from the configuration of the tray component stock device 29.
[0037] In the tray component stock device 29, a slide table device 123 is arranged in the internal space of the cover 109. The slide table device 123 places the magazine 41 thereon, and by passing through the magazine exchange window 111 along the second axis (Y axis), the magazine 41 can be moved (i.e., taken in and out) between the internal space of the cover 109 and the outside of the cover 109.
[0038] FIG. 9 is a schematic diagram of the interior of the tray component stock device 29 as seen from the aisle side. The tray component stock device 29 has multiple (e.g., four) fixed shelves 125 spaced apart in the vertical direction (along the Z direction). Of these, for example, a slide table device 123 is fixed to the second-lowest fixed shelf 125. That is, in the pallet stock section 43, of the magazines 41 stored in four vertical tiers, the magazine 41 in the second-lowest tier is placed on the slide table device 123. In the first embodiment, an example is described in which the slide table device 123 is installed in the second-lowest tier, but the slide table device 123 may be installed in any tier in the vertical direction. Furthermore, in the first embodiment, an example is described in which the slide table device 123 is installed only in the second-lowest tier, but the slide table device 123 may be installed in multiple tiers.
[0039] The slide table device 123 can manually drive a slide table 127 (see FIG. 17) on which the magazine 41 is placed to advance and retreat. The slide table device 123 may also be configured to include an advance and retreat drive unit 129 so that the slide table 127 on which the magazine 41 is placed automatically protrudes to the outside of the cover 109. In this case, the advance and retreat drive unit 129 includes, for example, an air cylinder 131 (see FIG. 18) which is an advance and retreat drive source, a valve for supplying operating air to the air cylinder 131, and the like.
[0040] The pallet transport unit 45 provided in the tray component stock device 29 includes a pallet handler 133 that moves pallets 39 between the pallet stock unit 43 and the tray component supply device 23. The pallet transport unit 45 includes a pallet handler lifting unit 135 that moves up and down (along the Z direction). The pallet handler lifting unit 135 is erected on the base unit 113 and has approximately the same height as the pallet stock unit 43. The pallet handler lifting unit 135 is provided with an erect stocker feed screw (not shown). This stocker feed screw is rotated by a handler lifting motor (not shown). An lifting base nut unit (not shown) is threadedly engaged with the stocker feed screw.
[0041] A lifting base 137 is fixed to the lifting base nut portion. A drawing device 141 is rotatably supported on the upper surface of the lifting base 137 via a handler shaft 139 that extends along the Z-axis. A handler motor 145, whose output shaft extends along the Z-axis, is fixed to the standing base portion 143 of the lifting base 137. A belt 147 is stretched between the output shaft of this handler motor 145 and the handler shaft 139. The handler motor 145, belt 147, and handler shaft 139 constitute a turning mechanism 149 (see FIG. 10). When the handler motor 145 of the turning mechanism 149 is driven, a rotational force is transmitted to the handler shaft 139, and the drawing device 141 is rotated around the handler shaft 139. The drawing device 141 has a handler engaging rod 81 and a pair of parallel pallet guides 151.
[0042] The pallet handler 133 moves up and down along the pallet stock unit 43, for example, when a handler lifting motor (not shown) is driven by a pallet transport control unit 153 (see FIG. 11). At this time, the pallet handler 133 can position the drawing device 141 at the height position of the pallet 39 corresponding to the storage address by specifying a storage address assigned to the pallet storage unit of the pallet stock unit 43. A tray parts stock device control unit 119 for controlling these components is provided below the pallet transport unit 45.
[0043] 10 is a plan view showing the layout of the tray component stock device 29 and the tray component supply device 23. The pallet stock unit 43 and the pallet transport unit 45 are aligned along the aisle 15 (see FIG. 1). That is, the tray component stock device 29 is installed with its long side oriented along the aisle 15. The pallet transport unit 45 of the tray component stock device 29 is connected to the component mounting device 13 in the direction along the Y-axis via the tray component supply device 23. As a result, the component mounting system 11 is installed in an L-shaped space in plan view, with the pallet stock unit 43 and the pallet transport unit 45 aligned along the long side along the X-axis, and the pallet stock unit 43 and the pallet transport unit 45 connected to the tray component supply device 23 in the direction intersecting the X-axis.
[0044] Therefore, the component mounting system 11 according to the first embodiment includes a component mounting device 13 that removes components 33 stored in a tray 31 using a component mounting section (e.g., a mounting head 35) and mounts them on a board 17, a tray component supply device 23 that supplies the tray 31 to a position where it can be removed by the component mounting section (e.g., the mounting head 35), and a tray component stock device 29 that replenishes the tray component supply device 23 with trays 31. The tray component stock device 29 is configured to include a pallet stock section 43 capable of storing a magazine 41 in the internal space of the cover 109, the magazine 41 allowing a pallet 39 on which a tray 31 containing components 33 is placed to be inserted and removed along a first axis (e.g., the X axis), a component storage body transport section (e.g., a pallet transport section 45) that transports the pallet 39 between the pallet stock section 43 and a component supply device (e.g., the tray component supply device 23), and a slide table device 123 that has a slide table 127 that can protrude from the inside to the outside of the cover 109 and that transports the magazine 41 between the inside and outside of the cover 109 along a second axis (e.g., the Y axis) that intersects the first axis within a horizontal plane.
[0045] In addition, in the tray component stock device 29, the slide table device 123 may further include a forward / backward driving unit 129 that causes the slide table 127 to protrude outside the cover 109.
[0046] Next, the configuration of a control system of the tray parts stock device 29 according to the first embodiment will be described.
[0047] 11 is a block diagram of the tray components stock device 29. The tray components stock device 29 includes a pallet transport unit 45, a slide table device 123, an operation unit 121, a connector 117, and a tray components stock device control unit 119. A power supply unit 155 external to the tray components stock device 29 is connected to the connector 117 via a power supply cable 157. An external power source 159 is connected to the power supply unit 155 via the power supply cable 157. The power supply unit 155 is also directly connected to the tray components stock device control unit 119 via a signal line 161.
[0048] The tray parts stock device control unit 119 includes a pallet transport control unit 153, a slide table control unit 163, and a storage unit 165.
[0049] When the pallet transport control unit 153 receives a request instruction for components 33 from the component mounting device 13, it refers to the component stock information stored in the memory unit 165 and sends an instruction to the pallet transport unit 45 to withdraw the pallet 39 of the tray 31 holding the components 33 from the pallet stock unit 43. Based on the instruction from the pallet transport control unit 153, the pallet transport unit 45 withdraws the corresponding pallet 39 from the pallet stock unit 43 and inserts the withdrawn pallet 39 into the magazine 41 of the replacement pallet storage unit 51 in the tray component supply device 23, thereby completing the supply of the pallet 39 to the tray component supply device 23. If, as a result of referring to the component stock information stored in the memory unit 165, the pallet transport control unit 153 finds that the requested components 33 are not available or that the remaining amount is low (for example, less than a specified amount), it displays a request instruction for components 33 to the tray component stock device 29 on the operation unit 121 and notifies the user that the components are out of stock or will soon be out of stock.
[0050] For example, when a pull-out command is input from the operation unit 121, the slide table control unit 163 sends an instruction to the slide table device 123 to switch the port of the valve connected to the air cylinder 131 (see FIG. 18) to the pull-out operating side. The slide table device 123 switches the above-mentioned valve based on the instruction from the slide table control unit 163. This switching causes the drive shaft of the air cylinder 131 (see FIG. 18) to advance, and the slide table 127 passes through the magazine exchange window 111 and advances to the aisle side. Furthermore, when a storage command is input from the operation unit 121, the slide table control unit 163 sends an instruction to the slide table device 123 to switch the port of the valve connected to the air cylinder 131 (see FIG. 18) to the storage operating side. The slide table device 123 switches the above-mentioned valve based on the instruction from the slide table control unit 163. This switching causes the drive shaft of the air cylinder 131 (see FIG. 18) to retract, and the slide table 127 is stored in the pallet stock unit 43. The slide table control unit 163 may drive the slide table 127 to move forward and backward in response to a forward and backward command from the component mounting device 13 or a magazine transport device (not shown).
[0051] The storage unit 165 is configured using a data recording device such as a flash memory, a hard disk drive (HDD), or a solid state drive (SSD), and stores stock information. The storage unit 165 stores component stock information indicating the quantity of components 33 to be supplied to the component mounting device 13, storage addresses (for example, a combination of the numbers of the magazines 41, pallets 39, and trays 31 on which each component 33 is placed), and whether or not the component mounting device 13 is being supplied.
[0052] Next, an example of a specific operation when transporting a pallet will be described.
[0053] 12 is an explanatory diagram of the operation of the pallet transport unit 45 immediately before pulling out a pallet 39 from the pallet stock unit 43. The pallet 39 is stored in the pallet stock unit 43 with the second engagement portion 77 disposed on the surface facing the pallet transport unit 45. To supply the pallet 39 to the tray component supply device 23, the pull-out device 141 of the pallet transport unit 45 moves in the vertical direction (direction along the Z axis), and the handler engagement rod 81 provided on the pull-out device 141 engages with the second engagement portion 77 provided on the desired pallet 39.
[0054] 13 is an explanatory diagram of the operation of the pallet transport unit 45 that has finished pulling out the pallet 39 from the pallet stock unit 43. The pull-out device 141, which has engaged the handler engaging rod 81 with the second engaging portion 77, pulls out the pallet 39 in the X direction together with the handler engaging rod 81 when a traction motor (not shown) is driven. The pallet 39 pulled out by the pull-out device 141 is supported from below on both short sides by a pair of pallet guides 151.
[0055] 14 is an explanatory diagram of the operation of the pallet conveying unit 45 in which the pull-out device 141 has rotated clockwise. Next, the pull-out device 141 supporting the pallet 39 is rotated 90 degrees clockwise by the drive of the handler motor 145. After the pallet 39 has rotated 90 degrees clockwise, the first engagement portion 75, with which the handler engagement rod 81 is not engaged, is positioned on the side of the replacement pallet storage unit 51. The pull-out device 141 is positioned so that the handler engagement rod 81 engaged with the second engagement portion 77 is on the aisle side in the direction along the Y axis.
[0056] FIG. 15 is an explanatory diagram of the operation of the pallet transport unit 45 after inserting the pallet 39 into the tray component supply device 23. The drawer 141 moves the handler engaging rod 81 in the Y direction. As the handler engaging rod 81 moves in the Y direction, the pallet 39 slides along the pallet guide 151 and is inserted into the replacement pallet storage unit 51 of the tray component supply device 23. If the pallet 39 is to be inserted at a different height, the lifting base 137 is raised or lowered to the desired height by the pallet handler lifting unit 135. After inserting the pallet 39 into the tray component supply device 23, the drawer 141 is moved up or down by the drive of the pallet handler lifting unit 135. After disengaging from the second engaging unit 77, the drawer 141 retreats away from the tray component supply device 23. The pallet transport unit 45 returns the handler engaging rod 81 to the retreated position, completing the supply of the pallet 39 to the tray component supply device 23.
[0057] In the tray component supply device 23, to recover an empty pallet 39 from which components 33 have been consumed to the pallet stock section 43, the empty pallet 39 is moved to the pallet stock section 43 by performing the above-described operation procedure in reverse.
[0058] Next, the slide table device 123 will be further described.
[0059] FIG. 16 is a plan view of the slide table device 123 in which the slide table 127 is housed. The tray component stock device 29 has a pallet stock section 43 and a slide table device 123. The pallet stock section 43 can house a magazine 41, which allows a pallet 39 carrying a tray 31 storing components 33 to be inserted and removed along a first axis (e.g., the X axis), in the internal space of the cover 109. The slide table device 123 has a slide table 127. The slide table 127 places the magazine 41 on the slide table 127 and moves the magazine 41 between the inside and outside of the cover 109 along a second axis (e.g., the Y axis) that intersects with the first axis within a horizontal plane. In other words, the slide table 127 can protrude from the inside to the outside of the cover 109.
[0060] The slide table device 123 supports the slide table 127 and has a slide rail 167 that extends and retracts along a second axis (for example, the Y axis). The slide table 127 moves between the outside and inside of the cover 109 as the slide rail 167 extends and retracts. The slide rail 167 has a fixed rail 169 (see FIG. 18), a connecting rail 171 (see FIG. 18), and a movable rail 173 (see FIG. 18).
[0061] The slide rail 167 has a fixed rail 169 fixed to the fixed shelf 125 of the pallet stock section 43 by an L-shaped bracket 175. The connecting rail 171 is connected in parallel to the fixed rail 169 and is slidable in the direction in which the fixed rail 169 extends. Approximately half of the connecting rail 171 can advance in the Y direction from the fixed rail 169. Once approximately half of the connecting rail 171 has advanced from the fixed rail 169, further advancement is restricted by a stopper mechanism (not shown). The movable rail 173 is connected in parallel to the connecting rail 171 and is slidable in the direction in which the connecting rail 171 extends. Approximately half of the movable rail 173 can advance in the Y direction from the connecting rail 171. Once approximately half of the movable rail 173 has advanced from the connecting rail 171, further advancement is restricted by a stopper mechanism (not shown).
[0062] Therefore, when the movable rail 173 is advanced, the slide rail 167 is supported by the fixed rail 169 and the connecting rail 171, which has advanced from the movable rail 173 by approximately half of its total length, over approximately half of the total length of the movable rail 173. This allows the movable rail 173 to be extended from the fixed rail 169 by approximately its entire length (see FIG. 18). This allows the slide rail 167 to have an extension length that is approximately the same as the storage space.
[0063] The slide table device 123 may have one or more slide rails 167. In the first embodiment, the slide table device 123 has two slide rails 167 that extend along a second axis (e.g., the Y-axis) and are arranged in parallel with a gap in the direction along a first axis (e.g., the X-axis). The two parallel slide rails 167 face each other with their movable rails 173 on the inside. A slide base 177 (see FIG. 17) with an L-shaped cross section is fixed to the inside of each movable rail 173 along the longitudinal direction of the movable rail 173. The pair of parallel slide bases 177 are connected to each other by a plurality of connecting plates 179. The slide base 177 and the connecting plates 179 constitute the slide table 127. The slide table 127 is sized to accommodate at least one magazine 41.
[0064] 17 is a perspective view of slide table 127. Slide base 177 is provided with a first restricting portion that restricts the position of magazine 41 in a first axis direction (e.g., X-axis) relative to slide table 127, and a second restricting portion that restricts the position of magazine 41 in a second axis direction (e.g., Y-axis) relative to slide table 127. Each slide base 177 has an L-shaped cross section with the horizontal piece facing inward and the upright piece standing outward.
[0065] The first restriction portion is an X alignment guide 181. A total of four pairs of X alignment guides 181 are fixed, spaced apart in the extension direction of each slide base 177. These X alignment guides 181 are upright plates perpendicular to side plates 83 (see FIG. 6) of magazine 41, and the pair of X alignment guides 181, provided at opposing positions on two slide bases 177, have inclined surfaces 183 that move away from each other as they extend upward. In other words, the pair of X alignment guides 181 are inclined upward in a Y shape when viewed from the direction along the Y axis (see FIG. 19). The above-mentioned X alignment rollers 93 (see FIG. 6) provided on side plates 83 of magazine 41 are fitted between the pair of X alignment guides 181 by being guided while sliding along inclined surfaces 183.
[0066] The second restriction portion is a Y alignment guide 187 (see FIG. 25). A total of four pairs of Y alignment guides 187 are fixed inside the four X alignment guides 181, spaced apart in the extension direction of each slide base 177. The Y alignment guides 187 are upright plates perpendicular to the side plates 83 of the magazine 41, and the pair of Y alignment guides 187, provided at opposing positions on the two slide bases 177, are formed into a trapezoidal shape with one corner of the quadrangle chamfered on the X alignment guide 181 side. In other words, the pair of Y alignment guides 187 are inclined, widening toward the end in an A-shape when viewed from the direction along the X axis (see FIG. 25). The pair of Y alignment guides 187 are positioned relative to the slide table 127 by the Y alignment rollers 99, provided on the underside of the bottom plate 87 of the magazine 41, being guided by the inclined surfaces 185 on the outer sides of both guides.
[0067] 18 is a plan view of the slide table device 123 with the slide table 127 advanced. The tray component stock device 29 may be provided with an advance / retract drive unit 129 in the slide table device 123. The advance / retract drive unit 129 enables the slide table 127 to automatically advance and retract between the outside of the cover 109 and the internal space.
[0068] In the first embodiment, the forward / backward driving unit 129 is disposed between two slide rails 167 (see FIG. 18).
[0069] The forward / backward driving unit 129 has a first rack gear 189, a second rack gear 191, a pinion gear 193, and a forward / backward driving source.
[0070] First rack gear 189 is fixed inside cover 109 with its longitudinal direction oriented parallel to a second axis (e.g., the Y axis). More specifically, first rack gear 189 is fixed to fixed shelf 125. Second rack gear 191 is attached to slide table 127 and disposed parallel to and facing first rack gear 189. Pinion gear 193 meshes with first rack gear 189 and second rack gear 191. The forward / backward driving source moves pinion gear 193 along the second axis (e.g., the Y axis).
[0071] In the first embodiment, the forward / backward drive source is, for example, an air cylinder 131 that moves a forward / backward drive shaft from a cylinder. A valve or the like that supplies operating air is connected to the air cylinder 131. By switching between multiple ports of the valve, it is possible to drive the forward / backward drive shaft of the air cylinder 131 in the direction of advancing or retracting.
[0072] A slider 195 is fixed to the tip of the forward / backward drive shaft of the air cylinder 131. The slider 195 moves linearly while being guided by a slider rail 197 in the direction along the Y axis fixed to the fixed shelf 125. The pinion gear 193 is rotatably supported by the slider 195, with the direction along the Z axis as the center of rotation.
[0073] 19 is a front view of slide table device 123 as seen from the aisle side. When viewed from the direction along the Y axis, slide table device 123 has a pair of parallel slide rails 167 fixed to fixed shelf 125 and extending outwardly in the direction along the Y axis. A slide base 177 is fixed to the inner side (i.e., the movable rail side) of each of the pair of slide rails 167. The pair of slide bases 177 constitute slide table 127 fixed by connecting plate 179. Air cylinder 131, which is the forward / backward drive source, is housed in a space surrounded by the pair of slide bases 177 and connecting plate 179 and is fixed to fixed shelf 125. Pinion gear 193, which is moved forward / backward by the forward / backward drive shaft of air cylinder 131, is sandwiched between first rack gear 189 fixed to fixed shelf 125 and second rack gear 191 fixed to slide base 177 and meshes with both rack gears.
[0074] 20 is a conceptual diagram of an advance / retract mechanism that uses an air cylinder 131 as an advance / retract drive source. The advance / retract drive unit 129 moves along the second axis (Y-axis) while rotatably supporting a pinion gear 193 on a slider 195. When the slide base 177 is housed inside the cover 109, the pinion gear 193 is located at the rear side of the first rack gear 189 (opposite the slide table advance side) and meshes with the pinion gear 193. At this time, the tip side of the second rack gear 191 fixed to the slide base 177 in the advance direction meshes with the pinion gear 193.
[0075] In the slide table device 123, when the air cylinder 131 is driven and the pinion gear 193 moves by an amount A in the advancing direction while meshing with the first rack gear 189, the second rack gear 191 meshing with the pinion gear 193 is advanced by an amount twice the amount of movement of the pinion gear 193 (A+A=2A).
[0076] FIG. 21 is a conceptual diagram of an advance / retract mechanism using a motor as the advance / retract drive source. The advance / retract drive unit 129 may be configured to use an advance / retract drive motor 199 as the advance / retract drive source. In this case, the fixed shelf 125 rotatably supports a pair of sprockets 201 whose rotation centers are along the X-axis and spaced apart along the Y-axis. An endless chain 203 is stretched across the pair of sprockets 201. The chain 203 rotatably supports a pinion gear 193 that meshes with both the first rack gear 189 and the second rack gear 191. By driving one of the sprockets 201 with the advance / retract drive motor 199, the pinion gear 193 moves along with the movement of the chain 203. As a result, similar to the movement using the air cylinder 131, the pinion gear 193 can be moved along the Y-axis while meshing with both rack gears. According to the advance / retract drive unit 129 using the advance / retract drive motor 199 as the advance / retract drive source, the slide table 127 can be advanced and retracted without using air pressure equipment.
[0077] FIG. 22 is a conceptual diagram showing a variable stroke structure of the advance / retract mechanism. The advance / retract drive unit 129 may also have a large-diameter pinion gear 205 and a small-diameter pinion gear 207 fixed coaxially. In this case, for example, the small-diameter pinion gear 207 (peripheral length A) meshes with the first rack gear 189, and the coaxially fixed large-diameter pinion gear 205 (peripheral length 2A) meshes with the second rack gear 191. With this advance / retract drive unit 129, if the movement distance of the small-diameter pinion gear 207 is A, the extension distance of the second rack gear 191 is A + 2A = 3A. In this way, the advance / retract drive unit 129 can freely set the stroke expansion ratio by combining multiple pinion gears 193 with different diameters (peripheral lengths). This allows the advance / retract drive unit 129 to realize a highly versatile advance / retract mechanism that can accommodate slide table devices 123 with different drawer lengths.
[0078] Next, the positioning operation of the slide table device 123 will be described.
[0079] 23 is a perspective view of magazine 41 positioned and placed on slide table 127. By placing magazine 41 on slide table 127, the magazine is positioned in each of the X-axis direction, Y-axis direction, and Z-axis direction.
[0080] 24 is an explanatory diagram of the positioning operation of slide table 127, mainly by X alignment guide 181. In slide table device 123, magazine 41 is placed on slide table 127 by being moved downward in the direction along the Z axis. This placing operation may be manual (i.e., performed by an operator) or automatic. When magazine 41 is lowered in a direction approaching slide table 127, X alignment roller 93 of magazine 41 comes into contact with a first restriction portion (e.g., X alignment guide 181). As X alignment roller 93 is guided by X alignment guide 181, the position of magazine 41 in the first axial direction (e.g., X axis direction) is determined relative to slide table 127.
[0081] 25 is an explanatory diagram of the positioning operation of slide table 127, mainly by Y alignment guide 187. In magazine 41, Y alignment roller 99 comes into contact with a second restriction portion (e.g., Y alignment guide 187) almost simultaneously with contact between X alignment guide 181 and X alignment roller 93. As Y alignment roller 99 is guided by inclined surface 185 of Y alignment guide 187, the position of magazine 41 in the second axial direction (e.g., Y axis direction) is determined relative to slide table 127.
[0082] When magazine 41 is moved to the final lowered position and placed thereon, the underside of bottom plate 87 comes into contact with Y alignment guides 187. When the underside of bottom plate 87 abuts against four Y alignment guides 187, magazine 41 is positioned in the Z axis relative to slide table 127. As a result, once magazine 41 has been placed on slide table 127, it is simultaneously positioned in the X, Y, and Z directions relative to slide table 127.
[0083] Next, the operation of the tray parts stock device 29 according to the first embodiment will be described.
[0084] The component stock device (e.g., tray component stock device 29) includes a magazine 41 that allows component storage units 69 (e.g., pallets 39 on which trays 31 are placed) storing components 33 to be inserted and removed along a first axis (e.g., the X-axis), a stocker (e.g., the pallet stock unit 43) that allows the magazine 41 to be inserted and removed along a second axis (e.g., the Y-axis) that intersects with the first axis within a horizontal plane, and a component storage unit transport unit (e.g., the pallet transport unit 45) that transports the component storage units 69 (e.g., the pallets 39) from the magazine 41 stored in the stocker along the first axis. The stocker has a housing (e.g., a cover 109) that forms an internal space that allows the magazine 41 to be stored. The housing has an opening (e.g., a magazine exchange window 111) that allows the magazine 41 to be inserted and removed along the second axis.
[0085] In the tray component stock device 29 according to the first embodiment, a tray 31 containing components 33 is placed on a pallet 39. The pallet 39 is removably inserted along a first axis and stored in a magazine 41. A plurality of pallets 39 are stored in the magazine 41 in multiple layers in the vertical direction. The magazine 41 is capable of transporting a plurality of stored pallets 39 at a time. A plurality of magazines 41 are stored in a stocker (e.g., a pallet stock section 43). A plurality of magazines 41 are stored in the pallet stock section 43 in multiple layers in the vertical direction. A pallet transport section 45 is integrally connected to the pallet stock section 43 along the first axis. The pallet transport section 45 transports pallets 39 one by one from the magazines 41 stored in the pallet stock section 43 along the first axis, while removing and inserting them.
[0086] In the tray component stock device 29, the pallet stock section 43 and the pallet transport section 45 are integrally connected. The pallet stock section 43 and the pallet transport section 45 constitute the tray component stock device 29. The pallet stock section 43 requires at least the installation space of one pallet. Similarly, the pallet transport section 45 also requires at least the installation space of one pallet. Therefore, the tray component stock device 29, which is made up of the pallet stock section 43 and the pallet transport section 45, is rectangular in plan view, requiring the installation space of at least two pallets.
[0087] In this tray component stock device 29, a pallet stock section 43 and a pallet transport section 45 are arranged along the passage 15. That is, the tray component stock device 29 is installed with the long side of the rectangle oriented along the passage 15 in a plan view.
[0088] In the tray components stock device 29, an opening (e.g., a magazine replacement window 111) is provided in the housing (e.g., a cover 109) of the pallet stock unit 43. The pallet stock unit 43 can insert and remove the magazine 41 through this magazine replacement window 111 along the second axis (Y axis). The second axis is a direction intersecting the first axis along the aisle 15. That is, as described above, in the tray components stock device 29, whose long side is installed along the aisle 15, the magazine replacement window 111 faces the side of the pallet stock unit 43 facing the aisle 15, of the pallet stock unit 43 and the pallet conveying unit 45 lined up along the aisle 15, and the magazine 41 can be inserted and removed from the pallet stock unit 43 in the direction (front-back direction) along the second axis (Y axis) from the aisle 15.
[0089] The tray parts stock device 29 allows the magazine 41 to be replaced in the direction along the Y-axis from the aisle side, making it easy to use the wide space above the aisle to replace the magazine 41. It also does not interfere with access to the feeder mounted on the carriage (for splicing, feeder replacement, or carriage replacement). Furthermore, when the transport robot automatically replaces the magazine, it is no longer necessary to go around to the side (left or right) of the tray parts stock device 29.
[0090] The tray component stock device 29 also includes a slide table device 123 that is arranged in the internal space, places the magazine 41 on it, and moves the magazine 41 between the internal space and the outside of the housing through the opening along the second axis.
[0091] In this tray component stock device 29, the pallet stock section 43 is provided with a slide table device 123 in the internal space covered by the cover 109. The slide table device 123 is provided corresponding to the position of the magazine exchange window 111. The slide table device 123 allows the magazine 41 to move between the internal space of the cover 109 and the outside of the cover 109 by passing through the magazine exchange window 111 along the second axis (Y axis).
[0092] A plurality of magazines 41 are stored in multiple vertical rows in the pallet stock section 43. The pallets 39 stored in each magazine 41 can be taken in and out by the pallet transport section 45 in the direction along the X axis.
[0093] One of the multiple magazines 41 stored in multiple stages in the vertical direction is placed on the slide table device 123. This one magazine 41 can be moved inside and outside the cover 109 through the magazine exchange window 111 by the slide table device 123. In other words, the tray parts stock device 29 can exchange only this one magazine 41 placed on the slide table device 123. The slide table device 123 serves as a transfer unit (i.e., an exchange unit) that exchanges magazines 41 one by one between the outside of the pallet stock unit 43 and the internal space.
[0094] Pallets 39, each storing components 33 in a tray 31, are successively drawn out by the pallet transport unit 45 from the magazine 41 placed on the slide table device 123. In the empty space in the magazine 41 from which the pallet 39 was drawn, another pallet 39 carrying an empty tray 31 from which components 33 have been consumed is stored by the pallet transport unit 45. In other words, the magazines 41 filled with components 33 placed on the slide table device 123 are successively replaced with empty pallets 39 by the pallet transport unit 45.
[0095] When all stored pallets 39 are replaced with empty pallets 39, the magazine 41 placed on the slide table device 123 is moved to the outside of the cover 109 (onto the aisle) by the slide table device 123. When the slide table device 123 is extended, the magazine 41 containing consumed parts and moved onto the aisle is replaced with a magazine 41 refilled with parts 33 by hand or a magazine transport device.
[0096] In this tray parts stock device 29, the magazine 41 is advanced onto the aisle through a magazine replacement window 111 provided on the aisle side of the pallet stock section 43, and furthermore by a slide table device 123, so that a magazine 41 having a weight of, for example, about 20 kg can be easily replaced.
[0097] The slide table device 123 may be manually pulled out from the aisle side. In this case, the slide table device 123 pulled out to the aisle side functions as a shelf, and the wide space above the aisle becomes a working space, facilitating manual replacement work.
[0098] In addition, in the tray component stock device 29, the slide table device 123 further includes a forward / backward driving section 129 that causes the slide table 127 on which the magazine 41 is placed to protrude outside the housing.
[0099] In this tray parts stock device 29, a forward / backward driving unit 129 is provided on the slide table device 123. When activated, the forward / backward driving unit 129 automatically moves the slide table 127 forward / backward between the outside of the cover 109 and the internal space through the magazine exchange window 111. This makes it easy to automate the exchange of magazines 41 when the self-propelled magazine transport device of the tray parts stock device 29 is traveling on a passageway, without the need for a large-scale elevator device or the like, and at low equipment cost.
[0100] In addition, the component mounting system 11 according to embodiment 1 includes a component mounting device 13 that removes components 33 stored in a component storage body 69 (e.g., tray 31) using a component mounting section (e.g., mounting head 35) and mounts the components on a board 17, a component supply device (e.g., tray component supply device 23) that supplies the component storage body 69 (e.g., tray 31) to a position where it can be removed by the component mounting section (e.g., mounting head 35), and a component stock device (e.g., tray component stock device 29) that replenishes the component storage body 69 (e.g., tray 31) to the tray component supply device 23. The tray component stock device 29 includes a magazine 41 that allows a component storage unit 69 (e.g., a pallet 39 on which a tray 31 is placed) storing components 33 to be inserted and removed along a first axis (e.g., the X-axis), a stocker (e.g., a pallet stock unit 43) that allows the magazine 41 to be inserted and removed along a second axis (e.g., the Y-axis) that intersects with the first axis in a horizontal plane, and a component storage unit transport unit (e.g., a pallet transport unit 45) that transports the component storage unit (e.g., the pallet 39) from the magazine 41 stored in the stocker along the first axis (e.g., the X-axis). The stocker (e.g., the pallet stock unit 43) has a housing (e.g., a cover 109) that forms an internal space that allows the magazine 41 to be stored. The housing has an opening (e.g., a magazine exchange window 111) that allows the magazine 41 to be inserted and removed along the second axis (e.g., the Y-axis).
[0101] In the component mounting system 11 according to the first embodiment, the pallet transport unit 45 transports the pallets 39 between the pallet stock unit 43 and the component mounting device 13. The pallets 39 are supplied in the order of the pallet stock unit 43, the pallet transport unit 45, and the component mounting device 13, and are recovered in the order of the component mounting device 13, the pallet transport unit 45, and the pallet stock unit 43. In other words, the pallets 39 are supplied from the pallet stock unit 43 via the pallet transport unit 45 to the component mounting device 13, and after the components 33 have been consumed and the pallets are empty, they are recovered from the component mounting device 13 to the pallet stock unit 43 via the pallet transport unit 45.
[0102] On a factory floor, a plurality of component mounting devices 13 are installed side by side in the left-right direction (along the X-axis), thereby forming a linear mounting line 27. Furthermore, on factory floors with high production volumes, a plurality of mounting lines 27 may be installed in parallel, sandwiching an aisle 15 along the X-axis that passes in front of and behind the component mounting devices 13. In this case, the mounting lines 27 and the aisles 15 are laid out parallel to each other and alternate with each other.
[0103] Here, if a new pallet stock section 43 and pallet conveying section 45 are connected in a straight line to the rear of the component mounting device 13 that has been installed conventionally, the pallet stock section 43 and pallet conveying section 45 will extend in a direction (along the Y-axis) that intersects with the extension direction of the mounting line 27 (along the X-axis).
[0104] As described above, because aisles 15 are laid out before and after mounting line 27, pallet stock unit 43 and pallet transport unit 45, which extend from the rear of component mounting device 13, protrude into aisle 15 to a considerable extent. On the other hand, if component mounting device 13 is provided with additional installation space to accommodate this protrusion in order to ensure aisle width during factory floor design at the time of new construction, this will result in an increase in the factory floor area and a decrease in area productivity.
[0105] In the component mounting system 11, the pallet stock unit 43 and the pallet transport unit 45 are integrally connected to form the tray component stock device 29. The pallet stock unit 43 requires an installation space equivalent to at least one pallet, and the pallet transport unit 45 also requires an installation space equivalent to at least one pallet. Therefore, the tray component stock device 29, which is made up of the pallet stock unit 43 and the pallet transport unit 45, is rectangular in shape in plan view, requiring an installation space equivalent to at least two pallets.
[0106] Therefore, the tray component stock device 29 has a pallet stock section 43 and a pallet conveying section 45 aligned along the aisle 15. That is, the tray component stock device 29 is installed with its long side aligned along the aisle 15. The pallet conveying section 45 of the tray component stock device 29 is connected to the component mounting device 13 along the Y-axis via the tray component supply device 23. As a result, the component mounting system 11 is installed in an L-shaped space in plan view, with the pallet stock section 43 and the pallet conveying section 45 aligned along the long side along the X-axis and connected to the tray component supply device 23 on the component mounting device side in a direction intersecting the X-axis. This allows the component mounting system 11 to set the pallet insertion / removal direction of the tray component supply device 23 perpendicular to the aisle 15 and the pallet insertion / removal direction of the pallet stock section 43 parallel to the aisle 15.
[0107] By arranging the stock positions in this L-shape, the component mounting system 11 can position the pallet stock section 43 at a right angle, which reduces the risk of the pallet stock section 43 protruding into the aisle 15 compared to when the pallet stock section 43, pallet conveying section 45 and tray component supply device 23 are arranged in series on a straight line that intersects with the aisle 15 between the equipment lines (in other words, the aisle width can be increased).
[0108] In this way, in the component mounting system 11, the pallet 39 is transferred by changing its direction between the direction along the X axis (left-right direction) between the pallet stock unit 43 and the pallet transport unit 45, and the direction along the Y axis (front-back direction) between the pallet stock unit 43 and the tray component supply device 23. This makes it possible to ensure both the aisle width and area productivity.
[0109] Furthermore, the component stock device (e.g., tray component stock device 29) according to embodiment 1 includes a stocker (e.g., pallet stock section 43) capable of storing a magazine 41 in the internal space of a housing (e.g., cover 109), which enables a component storage body (e.g., a pallet 39 on which trays 31 are placed) containing components 33 to be inserted and removed along a first axis (e.g., X-axis), and a slide table device 123 on which the magazine 41 is placed, which moves the magazine 41 between the inside and outside of the housing along a second axis (e.g., Y-axis) that intersects with the first axis within a plane along the horizontal plane, and which has a slide table 127 capable of protruding from the inside to the outside of the housing.
[0110] In the tray component stock device 29 according to the first embodiment, a stocker (e.g., a pallet stock unit 43) is provided with a slide table device 123 in an internal space covered by a housing (e.g., a cover 109). The slide table device 123 enables the magazine 41 to move between the internal space of the cover 109 and the outside of the cover 109 along a second axis (e.g., the Y axis).
[0111] A plurality of magazines 41 are stored in multiple vertical stages in the pallet stock section 43. The pallets 39 stored in each magazine 41 can be taken in and out in the direction along the X axis.
[0112] One of the multiple magazines 41 stored in multiple stages in the vertical direction is placed on the slide table device 123. This one magazine 41 can be moved inside and outside the cover 109 by the slide table device 123. In other words, the tray components stock device 29 can replace only this one magazine 41 placed on the slide table device 123. The slide table device 123 serves as a transfer unit (i.e., an exchange unit) that exchanges magazines 41 one by one between the outside of the pallet stock unit 43 and the internal space.
[0113] In the internal space of the pallet stock unit 43, pallets 39 each storing parts 33 in a tray 31 are successively pulled out from a magazine 41 placed on the slide table 127. In the empty space of the magazine 41 from which the pallet 39 was pulled out, a pallet 39 carrying an empty tray 31 from which the parts 33 have been consumed is stored. In other words, in the internal space of the pallet stock unit 43, the magazines 41 filled with parts placed on the slide table 127 are successively replaced with empty pallets 39.
[0114] When all the stored pallets 39 have been replaced with empty pallets 39, the magazine 41 placed on the slide table 127 is moved to the outside of the cover 109 (onto the passage) by the slide table device 123. The magazine 41 moved onto the passage by the extension of the slide table 127 is replaced with a new magazine 41 filled with parts 33 by hand or by a magazine transport device.
[0115] In this tray component stock device 29, the magazine 41 is fed onto the passage by the slide table device 123, so that the magazine 41, which has a weight of, for example, about 20 kg, can be easily replaced by hand.
[0116] The slide table device 123 may be manually pulled out from the aisle side. In this case, the slide table device 123 pulled out to the aisle side functions as a shelf, and the wide space above the aisle becomes a working space, facilitating manual replacement work.
[0117] In the tray component stock device 29, the slide table device 123 supports the slide table 127 and has a slide rail 167 that extends and retracts along a second axis (e.g., the Y axis). The slide table 127 moves between the outside and inside of the housing as the slide rail 167 extends and retracts.
[0118] In this tray component stock device 29, the slide table 127 is supported by slide rails 167. The slide rails 167 allow the slide table 127 to move between the interior space of the cover 109 and the outside of the cover 109. For example, a single slide rail 167 may support the slide table 127. That is, the slide table 127 may be moved back and forth between the inside and outside of the pallet stock section 43 by a single, extendable slide rail 167. When a single slide rail 167 is used, the support structure for the slide table 127 is simplified.
[0119] In addition, in the tray component stock device 29, the slide table device 123 has two slide rails 167 that extend along a second axis (e.g., the Y axis) and are arranged parallel to and spaced apart in a direction along the first axis (e.g., the X axis).
[0120] In this tray components stock device 29, the slide rail 167 is configured from two slide rails 167 that are parallel to each other and spaced apart in the direction along the X-axis. In the tray components stock device 29, the slide table 127 is supported by two slide rails 167, which increases the load capacity of the slide table 127. In addition, because the slide table 127 is supported by two slide rails 167 that are spaced apart in the direction perpendicular to the forward / backward direction, the magazine 41 can be supported more stably than when supported by a single slide rail 167.
[0121] In addition, in the tray component stock device 29, the slide table 127 is provided with a first regulating portion (e.g., X alignment guide 181) that regulates the position of the magazine 41 in a first axial direction (e.g., X axis direction) relative to the slide table 127, and a second regulating portion (e.g., Y alignment guide 187) that regulates the position of the magazine 41 in a second axial direction relative to the slide table 127.
[0122] In this tray component stock device 29, a first regulating portion and a second regulating portion are provided on the slide table 127. The first regulating portion (e.g., X alignment guide 181) regulates the position of the magazine 41 in a first axis (e.g., X axis) direction relative to the slide table 127. The second regulating portion (e.g., Y alignment guide 187) regulates the position of the magazine 41 in a second axis (e.g., Y axis) direction relative to the slide table 127. The Y alignment guide 187 also serves as a magazine receiver 187 that receives the magazine 41 placed from above. The Y alignment guide 187 also functions as the magazine receiver 187, thereby regulating the position of the magazine 41 in the Z axis direction relative to the slide table 127. This determines the relative position of the magazine 41 in the X, Y, and Z directions with respect to the slide table 127.
[0123] The component stock device (e.g., tray component stock device 29) also includes a stocker (e.g., pallet stock section 43) capable of storing a magazine 41 in the internal space of the housing, which enables component storage bodies 69 (e.g., pallets 39 on which trays 31 are placed) containing components 33 to be inserted and removed along a first axis (e.g., the X-axis), a slide table device 123 on which the magazine 41 is placed and which moves the magazine 41 between the inside and outside of the housing along a second axis (e.g., the Y-axis) that intersects with the first axis in a plane along the horizontal plane, and which has a slide table 127 capable of protruding from the inside to the outside of the housing, and an advance / retreat drive section 129 that causes the slide table 127 to protrude outside the housing.
[0124] In this tray parts stock device 29, the slide table 127 is driven by an advance / retract drive unit 129. When the advance / retract drive unit 129 is activated, it automatically moves the slide table 127 forward and backward between the outside of the cover 109 and the internal space. This makes it easy to automate the replacement of magazines 41 when the self-propelled magazine transport device of the tray parts stock device 29 is traveling on a passageway, without requiring a large-scale elevator device or the like, and at low equipment cost.
[0125] In the tray component stock device 29, the slide table device 123 supports the slide table 127 and has a slide rail 167 that extends and retracts along a second axis. The slide table 127 moves between the outside of the housing (e.g., the cover 109) and the inside of the housing (e.g., the cover 109) as the slide rail 167 extends and retracts.
[0126] In this tray component stock device 29, a slide table 127 is supported by slide rails 167 in a slide table device 123 equipped with an advance / retract drive unit 129. The slide rails 167 enable the slide table 127 to move between the interior space of the cover 109 and the outside of the cover 109. For example, a single slide rail 167 may support the slide table 127. That is, the slide table 127 may be moved forward and backward between the inside and outside of the pallet stock unit 43 by a single, extendable slide rail 167. When a single slide rail 167 is used, the support structure for the slide table 127 is simplified.
[0127] In addition, in the tray component stock device 29, the slide table 127 extends along the second axis and has two slide rails 167 arranged in parallel and spaced apart in the direction along the first axis.
[0128] In this tray components stock device 29, the slide rails 167 in the slide table device 123 equipped with the advance / retract drive unit 129 are configured with two slide rails 167 that are parallel to each other and spaced apart in the direction along the X-axis. In the tray components stock device 29, the slide table 127 is supported by two slide rails 167, which increases the load capacity of the slide table 127. Furthermore, because the slide table 127 is supported by two slide rails 167 that are spaced apart in the direction perpendicular to the advance / retract direction, the magazine 41 can be supported more stably than when supported by a single slide rail 167.
[0129] In addition, in the tray component stock device 29, the forward / backward driving unit 129 is disposed between the two slide rails 167.
[0130] In this tray components stock device 29, the slide table device 123 is equipped with two slide rails 167 that are parallel to each other and spaced apart in the direction along the X axis. The slide table device 123 has an advance / retract drive unit 129 installed in the space between the two slide tables 127. This allows the slide table device 123 to have a compact advance / retract drive mechanism equipped with the advance / retract drive unit 129.
[0131] In addition, in the tray component stock device 29, the forward / backward drive unit 129 has a first rack gear 189 fixed inside the housing with its longitudinal direction oriented parallel to the second axis, a second rack gear 191 attached to the slide table 127 and arranged parallel to and facing the first rack gear 189, a pinion gear 193 meshing with the first rack gear 189 and the second rack gear 191, and an forward / backward drive source (e.g., an air cylinder 131) that moves the pinion gear 193 along the second axis.
[0132] In this tray component stock device 29, the slide table 127 is driven to move forward and backward by an advance / retract drive unit 129. The advance / retract drive unit 129 rotatably supports a pinion gear 193 and moves it along a second axis. The pinion gear 193 meshes with a first rack gear 189 fixed inside the cover 109. Meanwhile, the pinion gear 193 is provided by a slide rail 167 so as to be able to move forward and backward relative to the cover 109, and also meshes with a second rack gear 191 that is disposed parallel to and facing the first rack gear 189. In other words, the pinion gear 193 is sandwiched between and meshes with the first rack gear 189 fixed inside the cover and the second rack gear 191 attached to the slide table 127, which is able to move forward and backward.
[0133] The pinion gear 193 is moved along the Y axis by an advance / retract drive source (for example, air cylinder 131) while being sandwiched between and meshing with both rack gears. When the slide table 127 is retracted inside the cover 109, the pinion gear 193 is positioned on the far side of the first rack gear 189 (opposite the slide table advance side) and meshes with it. At this time, the tip side of the second rack gear 191 attached to the slide table 127 in the advance direction meshes with the pinion gear 193.
[0134] When the forward / backward drive source (e.g., air cylinder 131) is driven and pinion gear 193 rolls in the forward direction while meshing with first rack gear 189, second rack gear 191 meshing with pinion gear 193 is extended in the forward direction by a distance twice the distance of the pinion gear 193.
[0135] As a result, in the tray component supply device 23, it is possible to keep the slide table device 123 compact in size while ensuring the movement stroke required for the slide table 127. In this advance / retract drive unit 129, by changing the gear ratio between the pinion gear 193 and the rack gear, it is possible to change the movement stroke of the slide table 127 relative to the movement stroke of the pinion gear 193 caused by the advance / retract drive source.
[0136] In addition, in the tray component stock device 29, the slide table 127 is provided with a first regulating portion (e.g., X alignment guide 181) that regulates the position in the first axial direction relative to the magazine 41, and a second regulating portion (e.g., Y alignment guide 187) that regulates the position in the second axial direction relative to the magazine 41.
[0137] In this tray component stock device 29, as magazine 41 is moved downward in the direction along the Z axis, X alignment roller 93 of magazine 41 comes into contact with a first restriction portion (for example, X alignment guide 181). As X alignment roller 93 is guided by X alignment guide 181, the position of magazine 41 in the first axial direction (for example, X axis direction) is determined relative to slide table 127.
[0138] When X alignment guide 181 and X alignment roller 93 come into contact with each other, Y alignment roller 99 of magazine 41 comes into contact with a second restriction portion (for example, Y alignment guide 187). As Y alignment roller 99 is guided by inclined surface 185 of Y alignment guide 187, the position of magazine 41 in the second axial direction (for example, the Y axis direction) is determined relative to slide table 127.
[0139] When magazine 41 is moved to the final lowered position and placed thereon, the lower surface of bottom plate 87 abuts against four Y alignment guides 187. This positions magazine 41 along the Z axis relative to slide table 127. As a result, once magazine 41 has been placed on slide table 127, it is simultaneously positioned in the X, Y, and Z directions relative to slide table 127.
[0140] In addition, the component mounting system 11 according to embodiment 1 includes a component mounting device 13 that removes components 33 stored in a component storage body 69 (e.g., tray 31) using a component mounting section (e.g., mounting head 35) and mounts the components on a board 17, a component supply device (e.g., tray component supply device 23) that supplies the component storage body 69 (e.g., tray 31) to a position where it can be removed by the component mounting section (e.g., mounting head 35), and a component stock device (e.g., tray component stock device 29) that replenishes the component storage body 69 (e.g., tray 31) to the tray component supply device 23. The tray component stock device 29 has a stocker (e.g., pallet stock section 43) that can store a magazine 41 in the internal space of the housing, which allows a component storage body 69 (e.g., a pallet 39 on which trays 31 are placed) containing components 33 to be inserted and removed along a first axis (e.g., the X axis), a component storage body transport section (e.g., the pallet transport section 45) that transports the component storage body 69 (e.g., the pallet 39) between the stocker and the tray component supply device 23, and a slide table device 123 that has a slide table 127 that can protrude from the inside to the outside of the housing and that mounts the magazine 41 and moves the magazine 41 between the inside and outside of the housing along a second axis (e.g., the Y axis) that intersects with the first axis in a plane along the horizontal plane.
[0141] In the component mounting system 11 according to the first embodiment, the pallet stock unit 43 includes a slide table device 123 in an internal space covered by the cover 109. The slide table device 123 enables the magazine 41 to move between the internal space of the cover 109 and the outside of the cover 109 along a second axis (Y axis).
[0142] A plurality of magazines 41 are stored in multiple vertical stages in the pallet stock section 43. The pallets 39 stored in each magazine 41 can be inserted and removed in the direction along the X axis.
[0143] One of the multiple magazines 41 stored in multiple stages in the vertical direction is placed on the slide table device 123. This one magazine 41 can be moved inside and outside the cover 109 by the slide table device 123. In other words, the tray components stock device 29 can replace only this one magazine 41 placed on the slide table device 123. The slide table device 123 serves as a transfer unit (i.e., an exchange unit) that exchanges magazines 41 one by one between the outside of the pallet stock unit 43 and the internal space.
[0144] Pallets 39, each storing components 33 in a tray 31, are sequentially moved from the magazine 41 placed on the slide table device 123 to the tray component supply device 23. Pallets 39 carrying trays 31 that have been emptied after components 33 have been consumed are returned from the tray component supply device 23 and stored in the vacant space of the magazine 41 from which the pallet 39 was pulled out. In other words, magazines 41 filled with components 33 placed on the slide table device 123 are sequentially replaced with empty pallets 39.
[0145] When all stored pallets 39 are replaced with empty pallets 39, the magazine 41 placed on the slide table device 123 is moved to the outside of the cover 109 (onto the aisle) by the slide table device 123. When the slide table device 123 is extended, the magazine 41 containing consumed parts and moved onto the aisle is replaced with a magazine 41 refilled with parts 33 by hand or a magazine transport device.
[0146] In this component mounting system 11, the magazine 41 is advanced onto the aisle from the aisle side of the pallet stock section 43 by the slide table device 123, so that the magazine 41, which weighs, for example, about 20 kg, can be easily replaced.
[0147] The slide table device 123 may be manually pulled out from the aisle side. In this case, the slide table device 123 pulled out to the aisle side functions as a shelf, and the wide space above the aisle becomes a working space, facilitating manual replacement work.
[0148] The component mounting system 11 also includes a component mounting device 13 that uses a component mounting section (e.g., a mounting head 35) to remove components 33 stored in a component storage body 69 (e.g., a tray 31) and mounts them on a board 17, a component supply device (e.g., a tray component supply device 23) that supplies the component storage body 69 (e.g., a tray 31) to a position where it can be removed by the component mounting section (e.g., the mounting head 35), and a component stock device (e.g., a tray component stock device 29) that replenishes the component storage body 69 (e.g., a tray 31) to the tray component supply device 23. The tray component stock device 29 includes a stocker (e.g., a pallet stock section 43) capable of storing a magazine 41 in the internal space of a housing (e.g., a cover 109), which allows a component storage body 69 (e.g., a pallet 39 on which a tray 31 is placed) containing components 33 to be inserted and removed along a first axis (e.g., the X axis); a component storage body transport section (e.g., a pallet transport section 45) that transports the component storage body 69 (e.g., the pallet 39) between the stocker and the tray component supply device 23; and a slide table device 123 that mounts the magazine 41 and moves the magazine 41 between the inside and outside of the housing (e.g., the cover 109) along a second axis (e.g., the Y axis) that intersects with the first axis in a plane along the horizontal plane, and has a slide table 127 that can protrude from the inside of the housing (e.g., the cover 109) to the outside of the housing (e.g., the cover 109). The slide table device 123 includes a forward / backward driving section 129 that causes the slide table 127 to protrude outside the housing.
[0149] In this component mounting system 11, the pallet stock unit 43 is provided with a slide table device 123 in an internal space covered by a cover 109. The slide table device 123 enables the magazine 41 to move between the internal space of the cover 109 and the outside of the cover 109 along a second axis (Y axis).
[0150] A plurality of magazines 41 are stored in multiple vertical stages in the pallet stock section 43. The pallets 39 stored in each magazine 41 can be inserted and removed in the direction along the X axis.
[0151] One of the multiple magazines 41 stored in multiple stages in the vertical direction is placed on the slide table device 123. This one magazine 41 can be moved inside and outside the cover 109 by the slide table device 123. In other words, the tray components stock device 29 can replace only this one magazine 41 placed on the slide table device 123. The slide table device 123 serves as a transfer unit (i.e., an exchange unit) that exchanges magazines 41 one by one between the outside of the pallet stock unit 43 and the internal space.
[0152] Pallets 39, each storing components 33 in a tray 31, are sequentially moved from the magazine 41 placed on the slide table device 123 to the tray component supply device 23. Pallets 39 carrying trays 31 that have been emptied after components 33 have been consumed are returned from the tray component supply device 23 and stored in the vacant space of the magazine 41 from which the pallet 39 was pulled out. In other words, magazines 41 filled with components 33 placed on the slide table device 123 are sequentially replaced with empty pallets 39.
[0153] When all stored pallets 39 are replaced with empty pallets 39, the magazine 41 placed on the slide table device 123 is moved to the outside of the cover 109 (onto the aisle) by the slide table device 123. When the slide table device 123 is extended, the magazine 41 containing consumed parts and moved onto the aisle is replaced with a magazine 41 refilled with parts 33 by hand or a magazine transport device.
[0154] In this component mounting system 11, the magazine 41 is advanced onto the aisle from the aisle side of the pallet stock section 43 by the slide table device 123, so that the magazine 41, which weighs, for example, about 20 kg, can be easily replaced.
[0155] The slide table device 123 may be manually pulled out from the aisle side. In this case, the slide table device 123 pulled out to the aisle side functions as a shelf, and the wide space above the aisle becomes a working space, facilitating manual replacement work.
[0156] In this component mounting system 11, the slide table 127 is driven by an advance / retract drive unit 129. When activated, the advance / retract drive unit 129 automatically moves the slide table 127 forward and backward between the outside of the cover 109 and the internal space. This makes it easy to automate the replacement of magazines 41 when the self-propelled magazine transport device is traveling on a passageway in the component mounting system 11, without requiring a large-scale elevator device or the like, and at low equipment cost.
[0157] Although various embodiments have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to such examples. It is clear that a person skilled in the art can conceive of various modifications, alterations, substitutions, additions, deletions, and equivalents within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present disclosure. Furthermore, the components of the various embodiments described above may be combined in any manner without departing from the spirit of the invention. [Industrial Applicability]
[0158] The present disclosure is useful as a tray component stock device and component mounting system that allows for easy magazine transfer using compact equipment, reduces the labor required for pallet replenishment, and increases area productivity. [Explanation of symbols]
