However, in recent years, in the SMT (Surface Mounting Technology) process, the frequency of electronic component replenishment during production 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 connector components, and the adoption of SMT for large components in downstream processes, which has led to larger tray components and reduced component counts per tray. In response to this, reducing labor in component replenishment requires increasing the number of components mounted on a single tray. However, from the perspective of area productivity, simply expanding the space of component mounting equipment is not feasible. For example, to automatically transfer magazines, the magazines must be fully extended from the stocker unit that transfers them. 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 in which the drive source is installed. Against this background, there is a demand to automate magazine transfer and to improve area productivity by placing more equipment in a limited space.

The present disclosure was devised in light of the above-mentioned conventional situation, and aims to provide a component stock device and component mounting system that facilitates magazine transfer using compact equipment, enables labor savings in pallet supply, and increases area productivity.

The present disclosure provides a parts stock device comprising: a stocker capable of storing a magazine in the internal space of a housing, the magazine allowing a part storage unit containing parts to be inserted and removed along a first axis; and a slide table device on which the magazine is placed and which moves the magazine between the inside and outside of the housing along a second axis that intersects the first axis within a plane along a horizontal plane, the slide table having a slide table that can protrude from the inside to the outside of the housing , wherein the slide table device supports the slide table and has a slide rail that extends and retracts along the second axis, the slide table moves between the outside and inside of the housing as the slide rail extends and retracts, and the slide table comprises a first regulating portion that regulates the position of the magazine in the first axial direction relative to the slide table, and a second regulating portion that regulates the position of the magazine in the second axial direction relative to the slide table.

The present disclosure also provides a parts stock device comprising: a stocker capable of storing a magazine in the internal space of a housing, the magazine allowing a part storage unit containing parts to be inserted and removed along a first axis; a slide table device having a slide table on which the magazine is placed and which moves the magazine between the inside and outside of the housing along a second axis that intersects the first axis within a plane along a horizontal plane and which can protrude from the inside to the outside of the housing; and an advance/retract drive unit which causes the slide table to protrude outside the housing, wherein the advance/retract drive unit has: a first rack gear fixed inside the housing with its longitudinal direction oriented parallel to the first axis; a second rack gear attached to the slide table and arranged parallel to and facing the first rack gear; a pinion gear that meshes with the first rack gear and the second rack gear; and an advance/retract drive source which moves the pinion gear along the second axis .

The present disclosure also provides a component mounting device that uses a component mounting unit to remove components stored in a component storage unit and mount them on a board, a component supply device that supplies the component storage unit to a position where it can be removed by the component mounting unit, and a component stock device that replenishes the component storage units to the component supply device, the component stock device including a stocker that can store a magazine in an internal space of a housing, the magazine allowing component storage units that store components to be inserted and removed along a first axis, a component storage unit transport unit that transports the component storage units between the stocker and the component supply device, and a component storage unit that can place the magazine and transport the magazine inside the housing along a second axis that intersects with the first axis in a plane along a horizontal plane. and a slide table device that moves the magazine between the inside and outside of the housing and has a slide table that can protrude from the inside to the outside of the housing , wherein the slide table device supports the slide table and has a slide rail that extends and retracts along the second axis, the slide table moves between the outside and inside of the housing as the slide rail extends and retracts, and the slide table is equipped with a first regulating portion that regulates the position of the magazine in the first axial direction relative to the slide table, and a second regulating portion that regulates the position of the magazine in the second axial direction relative to the slide table.

The present disclosure also provides a component mounting device that uses a component mounting unit to remove components stored in a component storage unit and mount them on a board, a component supply device that supplies the component storage unit to a position where it can be removed by the component mounting unit, and a component stock device that replenishes the component storage units to the component supply device, the component stock device including a stocker that can store a magazine in an internal space of a housing, the magazine allowing component storage units that store components to be inserted and removed along a first axis, a component storage unit transport unit that transports the component storage units between the stocker and the component supply device, and a component storage unit that can place the magazine and transport the magazine inside the housing along a second axis that intersects with the first axis in a plane along a horizontal plane. and an advance/ retract drive source that moves the pinion gear along the second axis.

Hereinafter, with reference to the drawings as appropriate, a detailed description of specific disclosed embodiments of a component stock device and component mounting system according to the present disclosure will be provided. However, more detailed description than necessary may be omitted. For example, detailed descriptions of well-known matters or redundant descriptions 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.

Figure 1 is a plan view of a factory floor where a component mounting system 11 according to embodiment 1 is installed. Below, in the diagrams with directional arrows, 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 and Y axes are orthogonal and contained in a horizontal plane. The Z axis is contained in a vertical plane that is orthogonal to the horizontal plane.

As shown in FIG. 1, multiple component mounting devices 13 are arranged closely together on the factory floor along an aisle 15 with an aisle width of W1. Each component mounting device 13 is provided with multiple parallel board transport conveyors 19, with the X-axis direction being the transport direction for boards 17, extending between the multiple 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.

Multiple component mounting devices 13 installed side by side make up a mounting line 27 on a factory floor. In factory floors with particularly high production volumes, multiple mounting lines 27 are installed in parallel, separated by an aisle 15 that runs along the X-axis and passes in front of and behind the component mounting devices 13. Of the multiple component mounting devices 13 installed side by side, the component mounting device 13 in which the tray component stock device 29 is integrally connected to the tray component supply device 23 makes up a component mounting system 11.

In the component mounting system 11, the longitudinal direction of the tray component stock device 29 is installed along the aisle 15, minimizing the reduction in the effective aisle width W2 between adjacent mounting lines 27.

Figure 2 is an overall configuration diagram of the component mounting system 11 shown in Figure 1. The component mounting system 11 according to embodiment 1 includes a component mounting device 13 that uses a mounting head 35 (see Figure 3) serving as a component mounting unit to remove components 33 (see Figure 4) stored on trays 31 (see Figure 4) and mount them on a board 17, a tray component supply device 23 that supplies trays 31 to a position where they can be removed by the mounting head 35, and a tray component stock device 29 that replenishes trays 31 in the tray component supply device 23.

The component mounting device 13 has a component mounting device main body 37. The tray component supply device 23 and tape component supply device 25 are connected to the aisle side of the component mounting device main body 37. The tray component stock device 29 is integrally connected to the component mounting device main body 37 via the tray component supply device 23.

The tray parts stock device 29, an example of a parts stock device, has a magazine 41 that allows pallets 39 (see Figure 4) on which trays 31 containing parts 33 (see Figure 4) are placed to be inserted and removed along a first axis (e.g., the X-axis). The tray parts stock device 29 has a pallet stock section 43 that functions as a stocker. The pallet stock section 43 allows the magazines 41 to be inserted and removed along a second axis (e.g., the Y-axis) that intersects the X-axis within a horizontal plane. The tray parts stock device 29 has a pallet transport section 45. The pallet transport section 45 transports pallets 39 along the X-axis from the magazines 41 stored in the pallet stock section 43. The pallets 39 transported from the pallet stock section 43 by the pallet transport section 45 are supplied to the tray parts supply device 23. In addition, the pallet transport unit 45 transports pallets 39 from the tray component supply device 23 that have consumed components 33 (i.e., all components 33 on the pallet 39 have been used to mount on boards 17) to the pallet stock unit 43 for collection.

Figure 3 is a conceptual diagram showing the cross-sectional structure of the component mounting system 11 shown in Figure 2. The component mounting device main body 37 is provided with a board transport section 49 on the upper surface of a base 47, which has 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 located on the aisle side of the base 47.

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 Figure 11). The tray component supply device 23 moves a 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 components 33 to the mounting head 35 by moving a pallet 39, which holds trays 31 on which components 33 (see Figure 4) are stored in a grid-like arrangement, to the component removal position.

The mounting head 35 is a multiple-head unit equipped with multiple unit transfer heads, each with 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 using 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 the component removal position and the component mounting position on the board transport unit 49.

The tray component stock device 29 has a pallet stock section 43 and a pallet transport section 45. The pallet stock section 43 stores multiple 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 transport section 45 in the direction along the X axis. The pallet 39 pulled out from the pallet stock section 43 by the pallet transport section 45 is moved to the tray component supply device 23 by the pallet transport section 45. The pallet transport section 45 can also move the pallet 39 in the opposite direction.

Figure 4 is a perspective view of a pallet 39 on which a tray 31 is placed. Figure 5 is an exploded perspective view of the pallet 39 shown in Figure 4.

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 the 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 embodiment 1, 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.

At least the top surface of the pallet 39 is made of a magnetic material. A tray 31 made of a non-magnetic material such as resin is placed on the top surface of the pallet 39. A plurality of parts 33 are aligned on the tray 31. The tray 31 is held in a predetermined position on the pallet 39 by a positioning device 67. The pallet 39 with the tray 31 placed on it constitutes a part storage unit 69. Note that the part storage unit 69 may also be a pallet 39 on which parts are placed and stored. Alternatively, the tray 31 may have the same external shape as the pallet 39 and the tray 31 itself may be used as the part storage unit 69.

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 perpendicular to each other, 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 is aligned with the inside corner of the pallet 39.

Once the tray 31 is positioned on the pallet in this way, a positioning device 67 is pressed against the surface opposite the surface pressed against the tray positioning piece 71, thereby securing it to the pallet 39. The positioning device 67 has, for example, a magnet. The positioning device 67 is strongly secured to the top surface of the pallet 39, which is made of a magnetic material, by magnetic force. This restricts movement of the tray 31 on the pallet 39 and secures it in place. The positioning device 67 has two lever portions 73 on both ends (see Figure 5), and each lever portion 73 is positioned above the top 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 top surface of the pallet 39, using the principle of leverage.

The pallet 39 also has 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 embodiment 1, the first engagement portion 75 engages with the changer engagement rod 79 (see Figure 10) of the pallet changer 53, and the second engagement portion 77 engages with the handler engagement rod 81, which is the traction portion of the pallet transport unit 45 shown in Figure 10.

Figure 6 is a perspective view of the magazine 41 containing the pallet 39. Figure 7 is a perspective view of the magazine 41 viewed diagonally from below.

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 Figure 7), forming an internal storage space in the shape of a rectangular cylinder 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 space between them along the Y-axis.

The inner surface of each side panel 83 is provided with ribs 91, both ends of which extend across the insertion/removal opening 89. The gaps between adjacent ribs 91 in the vertical direction (along the Z-axis) accommodate the insertion of a pair of parallel short sides of the pallet 39. 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 them to be inserted and removed through the insertion/removal opening 89.

As shown in Figure 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 section 95 is provided on the lower inside of the pair of side plates 83, close to the insertion/removal openings 89 at both ends. A tapered surface 97 is formed on the Y alignment section 95, and the tapered surface 97 is formed by a slope that thins the side plate 83 downward.

As shown in Figure 7, four Y alignment rollers 99 are provided on the underside of the bottom plate 87. Each Y alignment roller 99 is supported by a mounting piece 101 that hangs down perpendicularly from the underside of the bottom plate 87 to the side plate 83, and is rotatable around a center of rotation perpendicular to the mounting piece 101. The above-mentioned X alignment roller 93 and Y alignment roller 99 constitute a first alignment group 103.

A pair of parallel lower edges of the insertion/removal opening 89 at both ends of the bottom plate 87 form the X alignment section 105. The Y alignment section 95 having the tapered surface 97 described above and the X alignment section 105 form a second alignment group 107.

Figure 8 is an oblique view of the tray component stock device 29 shown in Figure 2. The pallet stock section 43 has a housing (e.g., cover 109) that forms an internal space capable of storing the magazine 41. This cover 109 has an opening (e.g., a magazine exchange window 111) that allows the magazine 41 to be inserted and removed along the second axis (Y-axis). The lower part of the magazine exchange window 111 of the pallet stock section 43 forms the base section 113. This base section 113 is provided with a docking section 115. The docking section 115 serves as a connection portion when, for example, a self-propelled magazine transport device (not shown) is used. The docking section 115 is provided with a connector 117, which electrically connects it to the tray component stock device control section 119 (see Figure 11). Furthermore, an operation section 121, such as a touch panel, electrically connected to the tray component stock device control section 119 (see Figure 11) is provided on the outer surface of the pallet transport section 45 on the aisle side. Note that this operation unit 121 may be omitted from the configuration of the tray component stock device 29.

The tray component stock device 29 has a slide table device 123 arranged in the internal space of the cover 109. The slide table device 123 places the magazine 41 on it, and by passing it through the magazine exchange window 111 along the second axis (Y axis), the magazine 41 can be moved (i.e., inserted and removed) between the internal space of the cover 109 and the outside of the cover 109.

Figure 9 is a schematic diagram of the interior of the tray component stock device 29, viewed 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, a slide table device 123 is fixed to, for example, the second-lowest fixed shelf 125. That is, in the pallet stock section 43, of the magazines 41 stored in four vertical tiers, the second-lowest magazine 41 is placed on the slide table device 123. In embodiment 1, 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. Also, in embodiment 1, 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.

The slide table device 123 can manually drive the slide table 127 (see Figure 17) on which the magazine 41 rests forward and backward. The slide table device 123 may also be configured to include a forward and backward drive unit 129 so that the slide table 127 on which the magazine 41 rests automatically protrudes outside the cover 109. In this case, the forward and backward drive unit 129 includes, for example, an air cylinder 131 (see Figure 18) which is the forward and backward drive source, and a valve that supplies operating air to the air cylinder 131.

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.

The lifting base 137 is fixed to the lifting base nut portion. The drawer 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 upright 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 form a rotation mechanism 149 (see Figure 10). When the handler motor 145 of the rotation mechanism 149 is driven, rotational force is transmitted to the handler shaft 139, causing the drawer device 141 to rotate around the handler shaft 139. The drawer device 141 has a handler engagement rod 81 and a pair of parallel pallet guides 151.

The pallet handler 133 moves up and down along the pallet stock unit 43, for example, by driving a handler lift motor (not shown) by the pallet transport control unit 153 (see Figure 11). At this time, the pallet handler 133 can position the pull-out device 141 at the height position of the pallet 39 corresponding to the storage address by specifying the 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 operations is provided below the pallet transport unit 45.

Figure 10 is a plan view showing the layout of the tray component stock device 29 and tray component supply device 23. The pallet stock section 43 and pallet transport section 45 are aligned along the aisle 15 (see Figure 1). That is, the tray component stock device 29 is installed with its long side oriented along the aisle 15. The pallet transport 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 pallet transport section 45 aligned along the X-axis on their long sides, and the pallet stock section 43 and pallet transport section 45 connected to the tray component supply device 23 in a direction intersecting the X-axis.

Therefore, the component mounting system 11 according to embodiment 1 comprises a component mounting device 13 that removes components 33 stored in a tray 31 using a component mounting unit (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 unit (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 allows pallets 39, which hold trays 31 containing components 33, to be inserted and removed along a first axis (e.g., the X axis); a component storage transport section (e.g., a pallet transport section 45) that transports the pallets 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 holds the magazine 41 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 the first axis in a horizontal plane, and has a slide table 127 that can protrude from the inside to the outside of the cover 109.

Furthermore, in the tray component stock device 29, the slide table device 123 may further include a forward/backward drive unit 129 that causes the slide table 127 to protrude outside the cover 109.

Next, we will explain the configuration of the control system of the tray component stock device 29 in embodiment 1.

Figure 11 is a block diagram of the tray parts stock device 29. The tray parts stock device 29 includes a pallet transport unit 45, a slide table device 123, an operation unit 121, a connector 117, and a tray parts stock device control unit 119. An external power supply unit 155 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 parts stock device control unit 119 via a signal line 161.

The tray parts stock device control unit 119 includes a pallet transport control unit 153, a slide table control unit 163, and a memory unit 165.

When the pallet transport control unit 153 receives a request instruction for a component 33 from the component mounting device 13, it references 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 component 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, after referencing the component stock information stored in the memory unit 165, the pallet transport control unit 153 finds that the requested component 33 is not available or that the remaining amount is low (for example, less than the specified amount), it displays a request instruction for the component 33 to the tray component stock device 29 on the operation unit 121 and notifies the user that the component is out of stock or will soon be out of stock.

When a pull-out command is input from the operation unit 121, for example, 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 also drive the slide table 127 forward and backward in response to a forward and backward command from the component mounting device 13 or the magazine transport device (not shown).

The memory unit 165 is configured using a data recording device such as a flash memory, HDD (Hard Disk Drive), or SSD (Solid State Drive), and stores stock information. The memory unit 165 stores component stock information indicating the quantity of components 33 to be supplied to the component mounting device 13, the storage address (for example, a combination of the magazine 41, pallet 39, and tray 31 numbers on which each component 33 is placed), and whether or not the component mounting device 13 is being supplied.

Next, we will explain an example of specific operations when transporting a pallet.

Figure 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 positioned 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 vertically (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.

Figure 13 is an explanatory diagram of the operation of the pallet transport unit 45 after the pallet 39 has been pulled out from the pallet stock unit 43. The pull-out device 141, with the handler engagement rod 81 engaged with the second engagement portion 77, pulls out the pallet 39 in the X direction together with the handler engagement rod 81 when the traction motor (not shown) is driven. The pallet 39 pulled out by the pull-out device 141 has both short sides supported from below by a pair of pallet guides 151.

Figure 14 is an explanatory diagram of the operation of the pallet transport unit 45 when the pull-out device 141 rotates clockwise. Next, the pull-out device 141 supporting the pallet 39 rotates 90 degrees clockwise by driving 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 replacement pallet storage unit 51 side. 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.

Figure 15 is an explanatory diagram of the operation of the pallet transport unit 45 after inserting a pallet 39 into the tray component supply device 23. The pull-out device 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 pallet handler lifting unit 135 raises or lowers the lifting base 137 to the desired height. After inserting the pallet 39 into the tray component supply device 23, the pull-out device 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 pull-out device 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.

In the tray component supply device 23, to retrieve an empty pallet 39 from which components 33 have been consumed to the pallet stock section 43, the above-described operational procedure is reversed to move the empty pallet 39 to the pallet stock section 43.

Next, we will further explain the slide table device 123.

Figure 16 is a plan view of the slide table device 123 in which the slide table 127 is stored. The tray component stock device 29 has a pallet stock section 43 and a slide table device 123. The pallet stock section 43 can store a magazine 41 in the internal space of the cover 109, which allows a pallet 39 on which a tray 31 storing components 33 is placed to be inserted and removed along a first axis (e.g., the X axis). The slide table device 123 has a slide table 127. The slide table 127 places the magazine 41 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.

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 cover 109 as the slide rail 167 extends and retracts. The slide rail 167 has a fixed rail 169 (see Figure 18), a connecting rail 171 (see Figure 18), and a movable rail 173 (see Figure 18).

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 parallel to the fixed rail 169 and is slidable in the direction of extension of the fixed rail 169. Approximately half of the connecting rail 171's length can be advanced from the fixed rail 169 in the Y direction. 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 parallel to the connecting rail 171 and is slidable in the direction of extension of the connecting rail 171. Approximately half of the movable rail 173's length can be advanced from the connecting rail 171 in the Y direction. 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).

As a result, when the movable rail 173 is extended, the slide rail 167 is supported by the fixed rail 169 and the connecting rail 171, which has extended approximately half its length from the movable rail 173. This allows the movable rail 173 to be extended from the fixed rail 169 by approximately its entire length (see Figure 18). This allows the slide rail 167 to have an extension length that is approximately the same as the storage space.

The slide table device 123 may have one or more slide rails 167. In embodiment 1, 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 each other at a distance in a direction along a first axis (e.g., the X axis). The two parallel slide rails 167 face each other with their respective movable rails 173 on the inside. A slide base 177 (see Figure 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 multiple connecting plates 179. The slide base 177 and connecting plates 179 constitute the slide table 127. The slide table 127 is sized to accommodate at least one magazine 41.

Figure 17 is a perspective view of the slide table 127. The slide base 177 is provided with a first restricting portion that restricts the position of the magazine 41 in the direction of a first axis (e.g., the X axis) relative to the slide table 127, and a second restricting portion that restricts the position of the magazine 41 in the direction of a second axis (e.g., the Y axis) relative to the 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.

The first restriction portion is the 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 the side plates 83 of the magazine 41 (see Figure 6). The pair of X alignment guides 181, located at opposing positions on the two slide bases 177, have inclined surfaces 183 that move away from each other as they extend upward. In other words, when viewed from the direction along the Y axis, the pair of X alignment guides 181 are inclined upward in a Y-shape (see Figure 19). The above-mentioned X alignment rollers 93 (see Figure 6) provided on the side plates 83 of the magazine 41 are fitted between the pair of X alignment guides 181 by being guided while sliding along the inclined surfaces 183.

The second restriction portion is the Y alignment guide 187 (see Figure 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. The pair of Y alignment guides 187, located 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, when viewed from the direction along the X axis, the pair of Y alignment guides 187 are inclined, fanning outward in an A-shape (see Figure 25). The pair of Y alignment guides 187 are positioned relative to the slide table 127 by the aforementioned Y alignment rollers 99, located on the underside of the bottom plate 87 of the magazine 41, being guided by the inclined surfaces 185 on the outside of both guides.

Figure 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 on 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.

In embodiment 1, the forward/backward drive unit 129 is positioned between two slide rails 167 (see Figure 18).

The forward/backward drive unit 129 has a first rack gear 189, a second rack gear 191, a pinion gear 193, and a forward/backward drive source.

The first rack gear 189 is fixed inside the cover 109 with its longitudinal direction oriented parallel to the second axis (e.g., the Y axis). More specifically, the first rack gear 189 is fixed to the fixed shelf 125. The second rack gear 191 is attached to the slide table 127 and is arranged parallel to and facing the first rack gear 189. The pinion gear 193 meshes with the first rack gear 189 and the second rack gear 191. The forward/backward drive source moves the pinion gear 193 along the second axis (e.g., the Y axis).

In embodiment 1, the forward/backward drive source is, for example, an air cylinder 131 that moves the forward/backward drive shaft from the cylinder. A valve or the like that supplies operating air is connected to the air cylinder 131. By switching between multiple ports, the valve can drive the forward/backward drive shaft of the air cylinder 131 in the forward or backward direction.

A slider 195 is fixed to the tip of the forward/backward drive shaft of the air cylinder 131. The slider 195 moves linearly, guided by a slider rail 197 that is fixed to the fixed shelf 125 and extends along the Y-axis. The pinion gear 193 is supported on the slider 195 so that it can rotate freely, with the Z-axis as its center of rotation.

Figure 19 is a front view of the slide table device 123 as seen from the aisle side. When viewed from the Y-axis direction, the slide table device 123 has a pair of parallel slide rails 167 fixed to the fixed shelf 125, extending outward along the Y-axis. A slide base 177 is fixed to the inside (i.e., the movable rail side) of each of the pair of slide rails 167. The pair of slide bases 177 form a slide table 127 fixed by a connecting plate 179. The air cylinder 131, which serves as the forward/backward drive source, is housed in the space surrounded by the pair of slide bases 177 and the connecting plate 179 and is fixed to the fixed shelf 125. The pinion gear 193, which is moved forward/backward by the forward/backward drive shaft of the air cylinder 131, is sandwiched between a first rack gear 189 fixed to the fixed shelf 125 and a second rack gear 191 fixed to the slide base 177 and engages with both rack gears.

Figure 20 is a conceptual diagram of the advance/retract mechanism that uses an air cylinder 131 as the advance/retract drive source. The advance/retract drive unit 129 moves along the second axis (Y-axis) while rotatably supporting the pinion gear 193 on the slider 195. When the slide base 177 is stored 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 engages with it. At this time, the tip side of the second rack gear 191 fixed to the slide base 177 in the advance direction engages with the pinion gear 193.

In the slide table device 123, when the air cylinder 131 is driven and the pinion gear 193 moves by a distance A in the forward direction while meshing with the first rack gear 189, the second rack gear 191 meshing with the pinion gear 193 is extended in the forward direction by a distance twice the distance traveled by the pinion gear 193 (A + A = 2A).

Figure 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 centers of rotation 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 meshed with both rack gears. The advance/retract drive unit 129, which uses the advance/retract drive motor 199 as the advance/retract drive source, allows the slide table 127 to advance/retract without using pneumatic equipment.

Figure 22 is a conceptual diagram showing the variable stroke structure of the advance/retract mechanism. The advance/retract drive unit 129 may also have the large-diameter pinion gear 205 and the 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 travel 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.

Next, we will explain the positioning operation of the slide table device 123.

Figure 23 is an oblique view of the magazine 41 positioned and placed on the slide table 127. By placing the magazine 41 on the slide table 127, the magazine 41 is positioned in the X-axis, Y-axis, and Z-axis directions.

Figure 24 is an explanatory diagram of the positioning operation of the slide table 127, mainly by the X alignment guide 181. In the slide table device 123, the magazine 41 is placed on the slide table 127 by moving it downward in the direction along the Z axis. This placement operation may be manual (i.e., performed by an operator) or automatic. When the magazine 41 is lowered in a direction approaching the slide table 127, the X alignment roller 93 of the magazine 41 comes into contact with a first restriction portion (e.g., the X alignment guide 181). As the X alignment roller 93 is guided by the X alignment guide 181, the position of the magazine 41 in the first axial direction (e.g., the X axis direction) is positioned relative to the slide table 127.

Figure 25 is an explanatory diagram of the positioning operation of the slide table 127, mainly by the Y alignment guide 187. The Y alignment roller 99 of the magazine 41 contacts the second restriction portion (e.g., Y alignment guide 187) almost simultaneously with the contact between the X alignment guide 181 and the X alignment roller 93. The Y alignment roller 99 is guided by the inclined surface 185 of the Y alignment guide 187, and the position of the magazine 41 in the second axial direction (e.g., Y axis direction) is determined relative to the slide table 127.

When the magazine 41 is moved to the final lowered position and placed thereon, the underside of the bottom plate 87 comes into contact with the Y alignment guides 187. The Z-axis position of the magazine 41 is determined relative to the slide table 127 as the underside of the bottom plate 87 abuts against the four Y alignment guides 187. As a result, once the magazine 41 has been placed on the slide table 127, it is simultaneously positioned in the X, Y, and Z directions relative to the slide table 127.

Next, we will explain the operation of the tray component stock device 29 according to embodiment 1.

A parts stock device (e.g., tray parts stock device 29) includes a magazine 41 that allows a parts storage unit 69 (e.g., a pallet 39 on which trays 31 are placed) containing parts 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 can insert and remove the magazine 41 along a second axis (e.g., the Y axis) that intersects the first axis within a horizontal plane, and a parts storage unit transport unit (e.g., the pallet transport unit 45) that transports the parts storage unit 69 (e.g., the pallet 39) from the magazine 41 stored in the stocker along the first axis. The stocker has a housing (e.g., the 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.

In the tray component stock device 29 according to the first embodiment, trays 31 containing components 33 are placed on pallets 39. The pallets 39 are stored in a magazine 41, with insertion and removal along a first axis. The magazine 41 stores multiple pallets 39 in multiple levels in the vertical direction. The magazine 41 is capable of transporting multiple stored pallets 39 at once. Multiple magazines 41 are stored in a stocker (e.g., a pallet stock section 43). The pallet stock section 43 stores multiple magazines 41 in multiple levels 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, inserting and removing them along the first axis.

In the tray parts stock device 29, the pallet stock section 43 and pallet transport section 45 are integrally connected. The pallet stock section 43 and pallet transport section 45 make up the tray parts stock device 29. The pallet stock section 43 requires at least the installation space of one pallet. The pallet transport section 45 also requires at least the installation space of one pallet. Therefore, the tray parts stock device 29, which is made up of the pallet stock section 43 and pallet transport section 45, is rectangular in plan view, requiring the installation space of at least two pallets.

In this tray component stock device 29, the pallet stock section 43 and pallet transport section 45 are aligned along the aisle 15. In other words, the tray component stock device 29 is installed with the long side of its rectangular shape aligned with the aisle 15 in a plan view.

The tray parts stock device 29 has an opening (e.g., a magazine replacement window 111) in the housing (e.g., cover 109) of the pallet stock section 43. The pallet stock section 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 parts stock device 29, whose long side is installed along the aisle 15, the magazine replacement window 111 faces the side of the pallet stock section 43 facing the aisle 15, of the pallet stock section 43 and pallet transport section 45 lined up along the aisle 15. This allows the magazine 41 to be inserted and removed from the pallet stock section 43 in the direction (front-to-back direction) along the second axis (Y-axis) from the aisle 15.

The tray parts stock device 29 allows magazine 41 replacement 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 cart-mounted feeder (for splicing, feeder replacement, or cart replacement). Furthermore, when the transport robot automatically replaces the magazine, there is no need to go around to the side (left or right) of the tray parts stock device 29.

The tray component stock device 29 also includes a slide table device 123 that is disposed 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.

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 passes through the magazine exchange window 111 along the second axis (Y axis), allowing the magazine 41 to move between the internal space of the cover 109 and the outside of the cover 109.

The pallet stock section 43 stores multiple magazines 41 in multiple vertical rows. The pallets 39 stored in each magazine 41 can be moved in and out along the X-axis by the pallet transport section 45.

One of the multiple magazines 41 stored in multiple vertical rows is placed on the slide table device 123. This 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 only exchange 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.

Pallets 39, each containing parts 33 stored in a tray 31, are successively pulled 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 pulled out, the pallet transport unit 45 stores a pallet 39 containing an empty tray 31 from which parts 33 have been consumed. In other words, the magazines 41 filled with parts 33 placed on the slide table device 123 are successively replaced with empty pallets 39 by the pallet transport unit 45.

When all stored pallets 39 have been replaced with empty pallets 39, the magazine 41 placed on the slide table device 123 is moved outside the cover 109 (onto the aisle) by the slide table device 123. By extending the slide table device 123, the magazine 41 with consumed parts moved onto the aisle is replaced with a magazine 41 refilled with parts 33, either by hand or using a magazine transport device.

In this tray parts stock device 29, the magazine 41 is advanced onto the aisle by the slide table device 123 through the magazine replacement window 111 located on the aisle side of the pallet stock section 43, making it possible to easily replace a magazine 41 weighing, for example, approximately 20 kg.

The slide table device 123 may also be manually pulled out from the aisle side. In this case, the slide table device 123 pulled out to the aisle side acts as a shelf, and the large space above the aisle becomes a work space, making manual replacement work easier.

In addition, in the tray component stock device 29, the slide table device 123 further includes a forward/backward drive unit 129 that causes the slide table 127 on which the magazine 41 is placed to protrude outside the housing.

In this tray parts stock device 29, a forward/backward drive unit 129 is provided on the slide table device 123. When activated, the forward/backward drive unit 129 automatically moves the slide table 127 forward and backward between the outside of the cover 109 and the internal space through the magazine replacement window 111. This makes it easier to automate the replacement of magazines 41 when the self-propelled magazine transport device is traveling along the aisle, without the need for a large-scale elevator device or the like, and at low equipment cost.

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 unit (e.g., mounting head 35) and mounts them 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 unit (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) in the tray component supply device 23. The tray component stock device 29 includes a magazine 41 that allows component storage units 69 (e.g., pallets 39 for carrying trays 31) containing 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 can insert and remove the magazine 41 along a second axis (e.g., the Y-axis) that intersects the first axis within 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 can accommodate the magazine 41. 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).

In the component mounting system 11 according to embodiment 1, the pallet conveying unit 45 conveys pallets 39 between the pallet stocking unit 43 and the component mounting device 13. The pallets 39 are supplied in the order of the pallet stocking unit 43, the pallet conveying unit 45, and the component mounting device 13, and are recovered in the order of the component mounting device 13, the pallet conveying unit 45, and the pallet stocking unit 43. In other words, the pallets 39 are supplied from the pallet stocking unit 43 via the pallet conveying 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 via the pallet conveying unit 45 to the pallet stocking unit 43.

On a factory floor, multiple component mounting devices 13 are installed side-by-side in the left-right direction (along the X-axis), forming a linear mounting line 27. Furthermore, on factory floors with high production volumes, multiple mounting lines 27 may be installed in parallel, separated by an aisle 15 along the X-axis that runs in front of and behind the component mounting devices 13. In this case, the mounting lines 27 and aisles 15 are laid out parallel to each other and alternate.

Here, if a new pallet stock unit 43 and pallet transport unit 45 are connected in a straight line to the rear of a conventionally installed component mounting device 13, the pallet stock unit 43 and pallet transport unit 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).

As mentioned above, because aisles 15 are laid out before and after the mounting line 27, the pallet stock unit 43 and pallet transport unit 45 extending from the rear of the component mounting device 13 protrude into the aisles 15 to a considerable extent. Meanwhile, if the component mounting device 13 were to be expanded with this protruding installation space to ensure aisle width during new factory floor design, this would result in an increase in the factory floor area and reduced area productivity.

In the component mounting system 11, the pallet stock unit 43 and 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 pallet transport unit 45, is rectangular in plan view, requiring an installation space equivalent to at least two pallets.

The tray component stock device 29 has its pallet stock section 43 and pallet transport 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 transport 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 pallet transport 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.

By arranging the stock positions in this L-shape, the component mounting system 11 can position the pallet stock unit 43 at a right angle, thereby reducing the risk of components protruding into the aisle 15 (in other words, making it possible to widen the aisle width), compared to when the pallet stock unit 43, pallet transport unit 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 this way, in the component mounting system 11, the pallets 39 are transferred by changing their direction between the X axis (left-right direction) between the pallet stock unit 43 and the pallet transport unit 45, and 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 aisle width and area productivity.

The parts stock device (e.g., tray parts stock device 29) according to embodiment 1 also includes a stocker (e.g., pallet stock unit 43) capable of storing a magazine 41 in the internal space of a housing (e.g., cover 109), which allows a parts storage unit (e.g., a pallet 39 on which trays 31 are placed) containing parts 33 to be inserted and removed along a first axis (e.g., the X axis), and 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 within a horizontal plane, and which has a slide table 127 that can protrude from the inside to the outside of the housing.

In the tray component stock device 29 according to the first embodiment, the stocker (e.g., the pallet stock unit 43) is provided with a slide table device 123 in an internal space covered by a housing (e.g., 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 (e.g., the Y axis).

The pallet stock section 43 stores multiple magazines 41 in multiple vertical rows. The pallets 39 stored in each magazine 41 can be inserted and removed along the X-axis.

One of the multiple magazines 41 stored in multiple vertical rows is placed on the slide table device 123. This magazine 41 can be moved inside and outside the cover 109 by the slide table device 123. In other words, the tray parts stock device 29 can only replace 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.

In the internal space of the pallet stock section 43, pallets 39 containing parts 33 stored in trays 31 are sequentially pulled out from magazines 41 placed on the slide table 127. In the empty space in the magazine 41 from which the pallets 39 have been pulled out, pallets 39 containing trays 31 from which the parts 33 have been consumed are stored. In other words, in the internal space of the pallet stock section 43, magazines 41 filled with parts placed on the slide table 127 are sequentially replaced with empty pallets 39.

When all stored pallets 39 have been replaced with empty pallets 39, the magazine 41 placed on the slide table 127 is moved outside the cover 109 (onto the aisle) by the slide table device 123. The magazine 41, which has been moved onto the aisle by the slide table 127 being extended, is then replaced with a new, fully stocked magazine 41 filled with parts 33 by hand or by a magazine transport device.

In this tray component stock device 29, the magazine 41 is advanced onto the path by the slide table device 123, making it possible to easily replace a magazine 41 weighing, for example, approximately 20 kg, even by hand.

The slide table device 123 may also be manually pulled out from the aisle side. In this case, the slide table device 123 pulled out to the aisle side acts as a shelf, and the large space above the aisle becomes a work space, making manual replacement work easier.

In addition, 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.

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. In other words, 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.

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).

In this tray component stock device 29, the slide rails 167 are 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 component 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 a direction perpendicular to the forward/backward direction, the magazine 41 can be supported more stably than when supported by a single slide rail 167.

In addition, in the tray component stock device 29, the slide table 127 is equipped with a first regulating portion (e.g., X alignment guide 181) that regulates the position of the magazine 41 in the 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 the second axial direction relative to the slide table 127.

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 the direction of a first axis (e.g., the X axis) relative to the slide table 127. The second regulating portion (e.g., Y alignment guide 187) regulates the position of the magazine 41 in the direction of a second axis (e.g., the Y axis) 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. By also functioning as the magazine receiver 187, the Y alignment guide 187 regulates the position of the magazine 41 in the Z axis direction relative to the slide table 127. This positions the magazine 41 relative to the slide table 127 in the X, Y, and Z directions.

The parts stock device (e.g., tray parts stock device 29) also includes a stocker (e.g., pallet stock unit 43) capable of storing a magazine 41 in the internal space of the housing, which allows parts storage units 69 (e.g., pallets 39 on which trays 31 are placed) containing parts 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 horizontal plane and which has a slide table 127 that can protrude from the inside to the outside of the housing; and an advance/retract drive unit 129 that causes the slide table 127 to protrude outside the housing.

In this tray parts stock device 29, 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 back and forth 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 along the aisle, without the need for a large-scale elevator device or the like, and at low equipment cost.

In addition, 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 and inside of the housing (e.g., cover 109) as the slide rail 167 extends and retracts.

In this tray component stock device 29, the 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 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. In other words, 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. Using a single slide rail 167 simplifies the support structure for the slide table 127.

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 parallel to and spaced apart in a direction along the first axis.

In this tray parts stock device 29, the slide table device 123 equipped with the forward/backward drive unit 129 has two slide rails 167 that are parallel to each other and spaced apart in the direction along the X-axis. In the tray parts stock device 29, the slide table 127 is supported by two slide rails 167, increasing 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 a direction perpendicular to the forward/backward direction, the magazine 41 can be supported more stably than when supported by a single slide rail 167.

In addition, in the tray component stock device 29, the forward/backward drive unit 129 is positioned between the two slide rails 167.

In this tray parts 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.

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 that meshes 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.

In this tray component stock device 29, the slide table 127 is driven to move forward and backward by the forward and backward drive unit 129. The forward and backward drive unit 129 rotatably supports the pinion gear 193 and moves it along the second axis. The pinion gear 193 meshes with the first rack gear 189 fixed inside the cover 109. Meanwhile, the pinion gear 193 is mounted on the slide rail 167 so that it can move forward and backward relative to the cover 109, and also meshes with the second rack gear 191, which is arranged parallel to and facing the first rack gear 189. In other words, the pinion gear 193 is sandwiched between and meshes with both the first rack gear 189 fixed inside the cover and the second rack gear 191 attached to the slide table 127, which can move forward and backward.

The pinion gear 193 is moved along the Y axis by a forward/backward drive source (e.g., 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 and meshed with the rear side of the first rack gear 189 (the side opposite the slide table advancement side). At this time, the tip side of the second rack gear 191 attached to the slide table 127 in the advancement direction is meshed with the pinion gear 193.

When the forward/backward drive source (e.g., air cylinder 131) is driven and the pinion gear 193 rotates in the forward direction while meshing with the first rack gear 189, the second rack gear 191 meshing with the pinion gear 193 is extended in the forward direction by a distance twice the distance traveled by the pinion gear 193.

This allows the tray component supply device 23 to keep the slide table device 123 compact while still ensuring the necessary movement stroke for the slide table 127. By changing the gear ratio between the pinion gear 193 and the rack gear in this forward/backward drive unit 129, 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 forward/backward drive source.

In addition, in the tray component stock device 29, the slide table 127 is provided with a first restriction portion (e.g., X alignment guide 181) that restricts the position in the first axial direction relative to the magazine 41, and a second restriction portion (e.g., Y alignment guide 187) that restricts the position in the second axial direction relative to the magazine 41.

In this tray component stock device 29, when the magazine 41 is moved downward in the direction along the Z axis, the X alignment roller 93 of the magazine 41 comes into contact with the first restriction portion (e.g., X alignment guide 181). The X alignment roller 93 is guided by the X alignment guide 181, and the position of the magazine 41 in the first axial direction (e.g., X axis direction) is determined relative to the slide table 127.

When the X alignment guide 181 and the X alignment roller 93 contact each other, the Y alignment roller 99 of the magazine 41 contacts a second restriction portion (e.g., the Y alignment guide 187). The Y alignment roller 99 is guided by the inclined surface 185 of the Y alignment guide 187, and the magazine 41 is positioned in the second axial direction (e.g., the Y axis direction) relative to the slide table 127.

When the magazine 41 is moved to the final lowered position and placed thereon, the underside of the bottom plate 87 abuts the four Y alignment guides 187. This positions the magazine 41 along the Z axis relative to the slide table 127. As a result, once the magazine 41 has been placed on the slide table 127, it is simultaneously positioned in the X, Y, and Z directions relative to the slide table 127.

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 unit (e.g., mounting head 35) and mounts them 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 unit (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) in the tray component supply device 23. The tray component stock device 29 includes a stocker (e.g., pallet stock unit 43) that can store magazines 41 in the internal space of the housing. The magazines 41 allow component storage units 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 component storage unit transport unit (e.g., the pallet transport unit 45) transports the component storage units 69 (e.g., the pallets 39) between the stocker and the tray component supply device 23. A slide table device 123 that carries 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 within a horizontal plane, and has a slide table 127 that can protrude from the inside to the outside of the housing.

In the component mounting system 11 according to embodiment 1, the pallet stock unit 43 includes a slide table device 123 in the 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 the second axis (Y axis).

The pallet stock section 43 stores multiple magazines 41 in multiple vertical rows. The pallets 39 stored in each magazine 41 can be inserted and removed along the X-axis.

One of the multiple magazines 41 stored in multiple vertical rows is placed on the slide table device 123. This magazine 41 can be moved inside and outside the cover 109 by the slide table device 123. In other words, the tray parts stock device 29 can only replace 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.

From the magazine 41 placed on the slide table device 123, pallets 39 storing parts 33 in trays 31 are sequentially moved to the tray component supply device 23. In the empty space in the magazine 41 from which the pallet 39 was pulled out, the pallet 39 carrying the tray 31 from which the parts 33 have been consumed and which is now empty is returned from the tray component supply device 23 and stored. In other words, the magazines 41 filled with parts 33 placed on the slide table device 123 are sequentially replaced with empty pallets 39.

When all stored pallets 39 have been replaced with empty pallets 39, the magazine 41 placed on the slide table device 123 is moved outside the cover 109 (onto the aisle) by the slide table device 123. By extending the slide table device 123, the magazine 41 with consumed parts moved onto the aisle is replaced with a magazine 41 refilled with parts 33 by hand or by a magazine transport device.

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, making it possible to easily replace a magazine 41 weighing, for example, approximately 20 kg.

The slide table device 123 may also be manually pulled out from the aisle side. In this case, the slide table device 123 pulled out to the aisle side acts as a shelf, and the large space above the aisle becomes a work space, making manual replacement work easier.

The component mounting system 11 also 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 unit (e.g., mounting head 35) and mounts them 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 unit (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 components stock device 29 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 allows a component storage unit 69 (e.g., a pallet 39 on which trays 31 are placed) storing components 33 to be inserted and removed along a first axis (e.g., X-axis), a component storage unit transport section (e.g., pallet transport section 45) that transports the component storage unit 69 (e.g., pallet 39) between the stocker and the tray components 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., cover 109) along a second axis (e.g., Y-axis) that intersects with the first axis in a plane along the horizontal plane, and that has a slide table 127 that can protrude from the inside of the housing (e.g., cover 109) to the outside of the housing (e.g., cover 109). The slide table device 123 includes an advance/retract drive unit 129 that causes the slide table 127 to protrude outside the housing.

In this component mounting system 11, the pallet stock unit 43 is equipped with a slide table device 123 in the internal space covered by the cover 109. 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 along the second axis (Y axis).

The pallet stock section 43 stores multiple magazines 41 in multiple vertical rows. The pallets 39 stored in each magazine 41 can be inserted and removed along the X-axis.

One of the multiple magazines 41 stored in multiple vertical rows is placed on the slide table device 123. This magazine 41 can be moved inside and outside the cover 109 by the slide table device 123. In other words, the tray parts stock device 29 can only replace 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.

From the magazine 41 placed on the slide table device 123, pallets 39 storing parts 33 in trays 31 are sequentially moved to the tray component supply device 23. In the empty space in the magazine 41 from which the pallet 39 was pulled out, the pallet 39 carrying the tray 31 from which the parts 33 have been consumed and which is now empty is returned from the tray component supply device 23 and stored. In other words, the magazines 41 filled with parts 33 placed on the slide table device 123 are sequentially replaced with empty pallets 39.

When all stored pallets 39 have been replaced with empty pallets 39, the magazine 41 placed on the slide table device 123 is moved outside the cover 109 (onto the aisle) by the slide table device 123. By extending the slide table device 123, the magazine 41 with consumed parts moved onto the aisle is replaced with a magazine 41 refilled with parts 33 by hand or by a magazine transport device.

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, making it possible to easily replace a magazine 41 weighing, for example, approximately 20 kg.

The slide table device 123 may also be manually pulled out from the aisle side. In this case, the slide table device 123 pulled out to the aisle side acts as a shelf, and the large space above the aisle becomes a work space, making manual replacement work easier.

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 back and forth between the outside of the cover 109 and the internal space. This makes it easier for the component mounting system 11 to automate the replacement of magazines 41 when the self-propelled magazine transport device is traveling along an aisle, without the need for a large-scale elevator device or the like, and at low equipment cost.
