Description

[Technical Field]

[0001] The present invention relates to a component stock device that stores a magazine holding component storage units, and a component mounting device that picks up components from a component storage unit drawn from a magazine stored in the component stock device and mounts them on a circuit board. [Background technology]

[0002] A component mounting apparatus is known in the art that uses a mounting head to pick up components supplied by a component supply unit and mount them on a circuit board. A tray feeder, which is used as one type of component supply unit in such a component mounting apparatus, includes a component stocking device that stores a magazine in a stocker, which holds component storage units containing components and allows them to be freely inserted and removed through an entrance, and a storage unit drawer that draws the component storage units from the magazines stored in the stocker. The component mounting apparatus is configured so that the mounting head picks up components from the component storage units drawn by the storage unit drawer.

[0003] Such a component stocking device is provided with a drop prevention unit to prevent component storage bodies from flying out and falling out of the magazine when the magazine is moved (see, for example, Patent Document 1 listed below). In Patent Document 1, the drop prevention unit is comprised of a rod-shaped stopper member extending in the vertical direction, and is provided on the magazine so as to be positioned in a restricting position that blocks a portion of the entrance and exit for the component storage bodies in the magazine. Because the drop prevention unit (stopper member) is biased toward the restricting position by an elastic body such as a spring, the component storage bodies will not fall out of the magazine unless the worker operates the drop prevention unit, allowing the worker to work safely when storing the magazine in the stocker. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2017-163006 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the configuration described in Patent Document 1, when inserting or removing a component storage unit into or from the magazine, the worker must move the fall-prevention unit from the restricting position to the non-restricting position (a position that does not block the entrance or exit for the component storage unit in the magazine) against the biasing force of the elastic body and maintain that position, which means the worker must handle the component storage unit with one hand, resulting in poor operability. To solve this problem, it is conceivable to provide a mechanism that can lock the fall-prevention unit in the non-restricting position, but this would require the worker to pay close attention not to forget to return the fall-prevention unit to the restricting position when storing the magazine in the stocker, which could increase the worker's workload.

[0006] Therefore, an object of the present invention is to provide a component stock device and a component mounting device that can improve the workability of inserting and removing component storage units into and from a magazine without increasing the workload of the worker. [Means for solving the problem]

[0007] The parts stock device of the present invention comprises a magazine that holds a parts storage unit containing parts so that it can be freely inserted and removed through an entrance and exit, and a stocker having a storage space for storing the magazine, wherein the magazine has a fall prevention part that is movable between a restricted position that restricts the insertion and removal of the part storage unit through the entrance and an unrestricted position that allows the part storage unit to be inserted and removed through the entrance and exit, and a locking means that locks the fall prevention part in the unrestricted position, and the stocker has an unlocking means that releases the state in which the fall prevention part is locked in the unrestricted position by the locking means when the magazine is being stored in the storage space.

[0008] The component mounting device of the present invention comprises the component stock device of the present invention described above, a storage unit drawer that draws the component storage unit out of the stocker through the entrance / exit of the magazine stored in the stocker, and a mounting head that picks up components from the component storage unit drawn out of the stocker by the storage unit drawer and mounts them on a board. [Effects of the Invention]

[0009] According to the present invention, the workability of inserting and removing component storage units into and from a magazine can be improved without increasing the workload of the worker. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a component mounting apparatus 1 according to one embodiment of the present invention. The component mounting apparatus 1 is an apparatus for manufacturing a mounted board by mounting components BH on a board KB, and includes a base 11, a board transport unit 12, a tray feeder 13, a mounting head 14, and a head moving mechanism 15.

[0012] The board transport unit 12 is made up of a conveyor mechanism and is provided on the base 11. The board transport unit 12 transports the board KB horizontally to load, position, and unload the board KB. For ease of explanation in this embodiment, the transport direction of the board KB by the board transport unit 12 is defined as the X direction (the left-right direction as seen from the worker OP), the horizontal direction perpendicular to the X direction is defined as the Y direction (the front-to-back direction as seen from the worker OP), and the up-down direction is defined as the Z direction. Furthermore, the back side of the Y direction as seen from the worker OP is defined as the front, and the front side as seen from the worker OP is defined as the rear.

[0013] The tray feeder 13 supplies components BH by positioning a component storage unit 16 containing the components BH at a component supply position at a predetermined height. The mounting head 14 is equipped with a nozzle 14N extending downward. The head movement mechanism 15 is, for example, an XY table, and moves the mounting head 14 horizontally. The mounting head 14 is moved by the head movement mechanism 15 between the tray feeder 13 and the board KB positioned by the board transport unit 12, and the nozzle 14N picks up and attaches the components BH supplied by the tray feeder 13 to the board KB.

[0014] 2 and 3, tray feeder 13 includes a dolly 21, a parts stock device 22, a drawer table 23, and a table lifting unit 24. Dolly 21 is movable on the floor by a plurality of wheels 21a and is installed behind base 11. Parts stock device 22 is installed behind dolly 21.

[0015] 1 and 2, parts stock device 22 includes stocker 31 and magazine 32. As shown in Fig. 2, storage space 31S for storing magazine 32 is formed inside stocker 31, and multiple magazine installation shelves 31T are arranged parallel to the Z direction within storage space 31S. The lower surface of ceiling panel 31B of stocker 31 and the upper and lower surfaces of each magazine installation shelf 31T are parallel to the horizontal plane.

[0016] 2, a magazine access opening 31K is provided in one of the left and right side walls (here, the left side wall) of stocker 31. Magazine access opening 31K is connected to storage space 31S, and an operator OP can install magazine 32 on magazine installation shelf 31T (i.e., in storage space 31S) through magazine access opening 31K.

[0017] 4, each magazine installation shelf 31T is provided with a magazine installation guide 31G. The magazine installation guides 31G are configured to be nested and are extendable in the X direction, and a portion of them can be protruded from the magazine access opening 31K to the outside of the stocker 31. Therefore, the operator OP can install the magazine 32 on the magazine installation guide 31G protruding to the outside of the stocker 31 (FIG. 4), and then simply move it toward the stocker 31 (arrow A shown in FIG. 4) to install the magazine 32 on the magazine installation shelf 31T (in the storage space 31S).

[0018] In Figure 5, the component storage unit 16 includes a tray TR and a pallet PL. The tray TR has a plurality of pockets PK arranged in a matrix, and the pallet PL is dish-shaped and has the tray TR placed on its top surface. Each of the plurality of pockets PK formed on the tray TR stores one component BH. The tray TR is fixed onto the pallet PL by a tray fixing device KG such as a magnet. Left and right engaging blocks BL are provided at the front end of the pallet PL, facing each other in the X direction.

[0019] 4, a storage unit drawer opening 31W connected to the storage space 31S is provided on the front wall of the stocker 31. The component storage units 16 in the magazines 32 placed on the magazine installation shelf 31T can be removed to the front of the stocker 31 through the storage unit drawer opening 31W, and the magazines 32 removed from the stocker 31 can be returned to the magazines 32 through the storage unit drawer opening 31W.

[0020] As described above, in this embodiment, the stocker 31 has a storage space 31S for storing the magazine 32, and is configured so that the component storage body 16 can be inserted into and removed from the magazine 32 through the storage body drawer opening 31W connected to the storage space 31S.

[0021] 1, 2, and 3, table lifting section 24 is located in front of parts stock device 22. As shown in Fig. 5, drawer table 23 is provided with storage body engaging section 23R and left and right drawer guides 23G.

[0022] 5, storage unit engaging portion 23R has a shape that extends in the left-right direction (X direction) as a whole, and each of its left and right ends is provided with a protrusion 23T that protrudes outward in the left-right direction. The left and right drawer guides 23G each extend in the Y direction and are arranged opposite each other in the X direction with storage unit engaging portion 23R in between.

[0023] 5, an engagement portion moving mechanism 23K is provided on the upper surface of the drawer table 23. The engagement portion moving mechanism 23K moves the storage body engagement portion 23R in the Y direction on the drawer table 23 (arrow B shown in FIG. 5).

[0024] 3 and 4, table lifting unit 24 includes left and right guide pillars 24T extending upward from carriage 21, and ball screws 24B extending in the Z direction. Ball screws 24B are driven by lifting motors 24M provided on carriage 21, and are rotated around an axis extending in the Z direction.

[0025] In Figure 5, a nut portion 23N is provided at the rear of drawer table 23. Ball screw 24B is threaded into nut portion 23N of drawer table 23, and guide pillar 24T guides movement of drawer table 23 in the Z direction while restricting rotation of drawer table 23 within a horizontal plane. Therefore, when lifting motor 24M rotates ball screw 24B, drawer table 23 moves up and down (arrow C shown in Figures 1 and 3).

[0026] Figure 6 shows the control system in component mounting apparatus 1. A control device 40 (see also Figure 1) provided in component mounting apparatus 1 controls the operation of board transport unit 12, tray feeder 13, mounting head 14, and head movement mechanism 15. Board transport unit 12 is controlled by control device 40 to load, position, and unload boards KB, and tray feeder 13 positions a component storage unit 16 pulled out of magazine 32 at the component supply position and supplies components BH to mounting head 14. Mounting head 14 and head movement mechanism 15 operate in cooperation to pick up components BH from component storage unit 16 and mount them on board KB.

[0027] When the tray feeder 13 positions a component storage unit 16 at the component supply position, first, the lift motor 24M drives the ball screw 24B to raise and lower the drawer table 23, and the upper surface of the drawer table 23 is positioned at the drawer preparation position, which is slightly higher than the height of the component storage unit 16 to be drawn. Once the upper surface of the drawer table 23 is positioned at the drawer preparation position, the engagement portion moving mechanism 23K moves the storage unit engagement portion 23R toward the magazine 32 (arrow B1 shown in FIG. 7(a)). Then, when the left and right protrusions 23T of the storage unit engagement portion 23R are positioned above the left and right engaged blocks BL of the pallet PL, the drawer table 23 is slightly lowered, thereby engaging the left and right protrusions 23T with the left and right engaged blocks BL (FIG. 7(a)).

[0028] When the left and right protrusions 23T of the storage unit engaging portion 23R engage with the left and right engaged blocks BL of the pallet PL, the storage unit engaging portion 23R is moved forward by the engaging portion moving mechanism 23K (arrow B2 shown in Figure 7(b)). As a result, the component storage unit 16 (or more specifically, the pallet PL) is drawn out of the magazine 32 and placed on the drawing table 23 (Figure 7(b)).

[0029] When the component storage unit 16 is drawn out onto the drawer table 23, the left and right ends of the component storage unit 16 (or more directly, the pallet PL) are guided by the left and right drawer guides 23G. As a result, the component storage unit 16 is drawn straight out in the Y direction relative to the drawer table 23 and placed on the drawer table 23 in the correct posture.

[0030] Once the component storage unit 16 is placed on the drawer table 23, the lift motor 24M rotates the ball screw 24B to raise the drawer table 23 and position the component storage unit 16 at the component supply position (FIG. 1). This enables the mounting head 14 to pick up a component BH from the component storage unit 16.

[0031] Next, the magazine 32 will be described. In Figures 8 and 9, the magazine 32 has a box shape that is open to the front as a whole. The magazine 32 includes a top plate 41, a bottom plate 42, and a pair of side plates 43 that are arranged opposite each other in the left-right direction (X direction).

[0032] 8 and 9, the opening at the front of the magazine 32 is a port 32F for inserting and removing the component storage unit 16. A plurality of slots 32S are arranged vertically inside the magazine 32. The component storage unit 16 can be inserted and removed from each slot 32S in a horizontal position through the port 32F.

[0033] 8, 9, and 10, a first bracket 51 is provided on the upper part of one of the left and right side plates 43 (here, the right side plate 43) of the magazine 32. As shown in Fig. 10, the first bracket 51 includes a main portion 51a that extends in the X direction and has its right end attached to the side plate 43, and a stopper portion 51b that bends and extends upward from the left end of the main portion 51a. An upper shaft hole 51H that penetrates the main portion 51a in the thickness direction (Z direction) is provided.

[0034] 8, 9, and 10, a rod member 52 is provided at the right end of the entrance 32F of the magazine 32 as a fall-off prevention member. The rod member 52 is a member that extends in the Z direction as a whole, and the upper and lower ends are each bent and extend horizontally to form horizontal portions 52H. The tip of each of the upper and lower horizontal portions 52H is bent vertically to form a shaft portion 52T. The two upper and lower horizontal portions 52H extend in the same direction and in parallel, and the two upper and lower shaft portions 52T extend in directions facing each other and are located on the same axis (swing axis 52J) (FIG. 10).

[0035] 10, of the two upper and lower shaft portions 52T, the upper shaft portion 52T is inserted from above into an upper shaft portion hole 51H of the first bracket 51. On the other hand, the lower shaft portion 52T is inserted from below into a lower shaft portion hole 42H (FIG. 10) provided in the bottom plate 42. Therefore, when the rod member 52 is attached to the top plate 41 and the bottom plate 42, it can swing about the swing axis 52J.

[0036] 8, 9, 10, and 11, a locked member 53 serving as a first engaging member is provided on the upper surface of first bracket 51. Locked member 53 is a flat plate-like member extending along the XY plane, and has a shaft insertion hole 53H formed in the center thereof, penetrating in the thickness direction (Z direction). Upper shaft 52T of rod member 52 is inserted from above into shaft insertion hole 53H of locked member 53, and then inserted into upper shaft hole 51H.

[0037] 10 and 11, the locked member 53 includes a rod member locking portion 53a, a spring member mounting portion 53b, an engaged portion 53c, and an operated portion 53d. The rod member locking portion 53a extends forward from the shaft insertion hole 53H side, and the spring member mounting portion 53b extends leftward in the left-right direction on the plane of Fig. 11 from the shaft insertion hole 53H side. The engaged portion 53c extends rearward from the shaft insertion hole 53H side, and the operated portion 53d extends rightward in the left-right direction on the plane of Fig. 11 from the shaft insertion hole 53H side.

[0038] 10 and 11, a rod member locking groove 53M is formed in the rod member locking portion 53a. The rod member locking groove 53M extends from the tip (front end) of the rod member locking portion 53a toward the shaft insertion hole 53H. The upper part of the rod member 52 is locked in the rod member locking groove 53M (FIG. 11). Therefore, when the rod member 52 swings about the swing axis 52J, the locked member 53 also rotates integrally with the rod member 52 about the swing axis 52J.

[0039] The rod member 52 swings about the swing axis 52J to a restricting position (FIGS. 11 and 12(a)) where it is located in front of the entrance 32F of the component storage unit 16 and blocks a portion of the entrance 32F, or a restricted position (FIG. 12(b)) where it is located outward (to the right in this case) from the front of the entrance 32F and opens the entrance 32F. When the rod member 52 is in the restricting position, even if an attempt is made to pull the component storage unit 16 outward (to the front) of the magazine 32, a portion (a part on the right side) of the component storage unit 16 interferes with the rod member 52, preventing the component storage unit 16 from being pulled out. Therefore, when the rod member 52 is in the restricting position, the component storage unit 16 is prevented from flying out of the magazine 32 against the operator's intention.

[0040] On the other hand, when the rod member 52 is in the non-restricted position, the component storage body 16 being pulled out of the magazine 32 does not interfere with the rod member 52. Therefore, when the rod member 52 is in the non-restricted position, the magazine 32 can be pulled out of the component storage body 16.

[0041] In this embodiment, the rod member 52 as a fall prevention part is freely movable between a restricting position that restricts the insertion and removal of the component storage body 16 through the entrance / exit 32F of the component storage body 16 in the magazine 32, and a non-restricting position that allows (does not restrict) the insertion and removal of the component storage body 16 through the entrance / exit 32F.

[0042] 8, 9, 10, and 11, a second bracket 54 is provided on the right side of the upper surface of the top plate 41 (closer to the center of the magazine 32 in the left-right direction than the first bracket 51). The second bracket 54 has a base 54a that extends along the XY plane and a wall 54b that extends upward from the rear edge of the base 54a. The base 54a is attached to the upper surface of the top plate 41 with a plurality of screws 54S (FIGS. 10 and 11).

[0043] 8, 9, 10 and 11, a return spring 55 serving as a biasing means is provided between the spring member mounting portion 53b of the locked member 53 and the base portion 54a of the second bracket 54. The return spring 55 is made of a tension spring, and biases the rod member 52 toward the second bracket 54 (i.e., toward the center portion of the magazine 32 in the left-right direction) (arrow D shown in FIGS. 11 and 12(a)).

[0044] 8, 9, 10, and 11, a locking member 56 serving as a second engaging member is provided on the wall portion 54b of the second bracket 54. The locking member 56 has a shape that extends in the X direction (substantially horizontally) as a whole, and its middle portion is attached to the wall portion 54b. The locking member 56 is attached to the wall portion 54b by a pin 56P whose axis 56J (FIG. 10) extends in the Y direction, and is capable of swinging freely within the XZ plane like a seesaw.

[0045] 10 and 11, the locking member 56 has an engaging portion 56a extending to the right of the pin 56P and an operating portion 56b extending to the left of the pin 56P. The tip of the engaging portion 56a is bent slightly forward.

[0046] When no operating force is being applied to operating portion 56b, locking member 56 is in a position where the lower edge of engaging portion 56a is in contact with table top 41 while the lower edge of operating portion 56b is separated from table top 41 due to weight balance caused by its own weight (FIG. 11). In this state, a gap LS is formed between operating portion 56b and table top 41 as an allowance for pressing down operating portion 56b. The position of locking member 56 where no operating force is being applied to operating portion 56b of engaging portion 56a and engaging portion 56a is in contact with table top 41 will be referred to as the "locked position" below.

[0047] When the operator OP presses the operating portion 56b of the locking member 56 positioned in the operated position downward (arrow E shown in FIG. 13), the locking member 56 swings around the axis 56J of the pin 56P, and the engaging portion 56a moves away from the top plate 41 (arrow F shown in FIG. 13). As a result, a gap SP of a certain height is formed between the engaging portion 56a and the top plate 41. Hereinafter, the position of the locking member 56 where the engaging portion 56a moves away from the top plate 41 and the gap SP is formed below the engaging portion 56a in this way will be referred to as the "unlocked position."

[0048] When the rod member 52 is moved from the restricted position to the non-restricted position (arrow G in FIGS. 12(b) and 14), the locked member 53 rotates counterclockwise in a plan view (from FIG. 12(a) to FIG. 12(b)). As a result, the engaged portion 53c of the locked member 53 moves from a position to the right of the engaging portion 56a of the locking member 56 (FIG. 12(a)) along an arc-shaped movement path R (FIG. 12(b)) centered on the swing axis 52J. If the locking member 56 is in the unlocked position at this time, the engaged portion 53c passes below the engaging portion 56a and moves forward, abutting against the stopper portion 51b of the first bracket 51 from behind (FIG. 14). Note that the operated portion 53d of the locked member 53 is always located outside the magazine 32 (to the right of the right side plate 43), regardless of the rotational position of the locked member 53.

[0049] After engaged portion 53c of locked member 53 has passed under engaging portion 56a of locking member 56 as described above, when locking member 56 is positioned at the locked position (FIG. 15), engaging portion 56a of locking member 56 is positioned on movement path R along which locked member 53 has traveled. Therefore, when operator OP releases rod member 52 after locking member 56 has been positioned at the locked position, engaged portion 53c of locked member 53, which rotates clockwise due to the biasing force of return spring 55, comes into contact with engaging portion 56a from the front (locking member 56 and locked member 53 engage), and rod member 52 is locked at the non-restricted position (FIGS. 15 and 16).

[0050] Furthermore, when the locking member 56 is moved (swingn) to the unlocked position from a state in which the rod member 52 is locked in the non-restricted position, the engagement between the locking member 56 and the locked member 53 is released. As a result, the locked member 53 is urged by the urging force of the return spring 55 to rotate clockwise in a plan view and return to the restricted position. The spring member attachment portion 53b then stops at a position where it abuts against the stopper portion 51b of the first bracket 51 from the front (FIGS. 11 and 12(a)).

[0051] In this embodiment, the locked member 53 (first engaging member) that moves integrally with the rod member 52, and the locking member 56 (second engaging member) that locks the rod member 52 in the non-restricted position by engaging with the locked member 53 (positioning on the movement path R of the engaged portion 53c) when the rod member 52 is in the non-restricted position, and releases the lock by disengaging from the locked member 53 (retracting from the movement path R of the engaged portion 53c), form a locking means 60 that locks the rod member 52 in the non-restricted position (Figures 8 and 9).

[0052] When the rod member 52 is locked in the non-restricted position by the locking means 60, it is possible to take the component storage unit 16 in or out of the magazine 32 (FIG. 17), but at this time the operator OP can release his or her hands from the rod member 52. This allows the operator OP to handle the component storage unit 16 with both hands, which not only makes it easier to take the component storage unit 16 in or out of the magazine 32, but also allows the operator OP to handle the component storage unit 16 carefully, making it less likely that a component BH will fall out of the component storage unit 16.

[0053] 18(a), (b), and (c), an unlocking means 70 is provided on the underside of the magazine installation shelf 31T (or ceiling board 31B). As shown in FIGS. 19(a), (b), (c), and (d), the unlocking means 70 includes a base portion 71 attached to the underside of the magazine installation shelf 31T (ceiling board 31B), and a roller 72 attached to the base portion 71. The roller 72 is pivotally supported by a pivot pin 73 having an axis extending in the Y direction, and is rotatable within the XZ plane.

[0054] In Figures 18(a), (b), and (c), the aforementioned magazine installation guide 31G provided on the top surface of each magazine installation shelf 31T is configured in a nested manner, with a fixed part 81 fixed to the magazine installation shelf 31T, an intermediate movable part 82 that slides on the outside of the fixed part 81, and an outer movable part 83 that slides on the outside of the intermediate movable part 82, and is freely expandable and contractible in the X direction.

[0055] When storing magazine 32 in storage space 31S, operator OP first pulls out outer movable part 83 and part of intermediate movable part 82 of magazine installation guide 31G from stocker 31, and positions outer movable part 83 outside magazine 32, and further outside stocker 31. Then, magazine 32 is placed on the pulled-out outer movable part 83 (FIG. 18(a)), and the magazine 32 is pushed into storage space 31S of stocker 31 together with outer movable part 83 (arrow H shown in FIG. 18(b)). As a result, intermediate movable part 82 slides relative to fixed part 81, and outer movable part 83 slides relative to intermediate movable part 82, so that magazine 32 is stored in storage space 31S (FIG. 18(c)).

[0056] 19(a), when the magazine 32 is stored in the storage space 31S, the height of the lower end of the unlocking means 70 (here, the lower end of the roller 72) is lower than the upper surface of the operating part 56b (the other end) when the engaging part 56a (one end) of the locking member 56 is positioned on the movement path R of the engaged part 53c, and a height gap GP is generated between the lower end of the roller 72 and the upper surface of the operating part 56b (FIG. 19(a)). Therefore, during the process of storing the magazine 32 in the storage space 31S of the stocker 31, the operating part 56b of the locking member 56 provided on the magazine 32 abuts against the roller 72 of the unlocking means 70 provided on the stocker 31 (FIG. 19(a) → FIG. 19(b)), and then, as the magazine 32 is further pushed into the stocker 31, the operating part 56b of the locking member 56 is pressed down by the roller 72 (FIG. 19(b) → FIG. 19(c)).

[0057] When the operating portion 56b of the locking member 56 is pressed down by the roller 72, the locking member 56 swings around the axis 56J of the pin 56P to the unlocked position (FIG. 19(c)). If the locking member 56 and the locked member 53 are engaged at that time, the engagement is released. The locked member 53 then rotates counterclockwise due to the biasing force of the return spring 55, and the rod member 52 returns to the restricted position (FIG. 16 → FIG. 12(a)). Therefore, even if the magazine 32 is stored in the stocker 31 with the rod member 52 in the non-restricted position, the rod member 52 is automatically returned to the restricted position. As the storing operation of the magazine 32 into the stocker 31 progresses and the roller 72 of the lock releasing means 70 moves away from the operating portion 56b of the locking member 56 (FIG. 19(d)), the locking member 56 returns to the locked position by its own weight. The means for returning the locking member 56 to the locked position is not limited to its own weight, but may be a spring or other resilient member that biases the engaging portion 56a toward the top plate 41 to return it to the locked position.

[0058] When the magazine 32 is stored in the stocker 31, the operated portion 53d of the locked member 53 provided in the magazine 32 is adapted to engage with an operating portion (not shown) that is driven by an actuator (not shown) provided in the stocker 31. Therefore, after the magazine 32 is stored in the stocker 31, the actuator is operated to rotate the locked member 53 via the operating portion and the operated portion 53d that engages with it, thereby holding the rod member 52 in the non-restricted position without relying on the locking means 60.

[0059] As described above, in the tray feeder 13 of this embodiment, in the process of storing the magazine 32 in the storage space 31S, the lock release means 70 provided in the stocker 31 operates the lock means 60 provided in the magazine 32, thereby releasing the state in which the rod member 52 has been locked in the non-restricted position by the lock means 60. Therefore, even if the operator OP positions the rod member 52 in the non-restricted position by the lock means 60 and then forgets to release that state (the state in which the rod member 52 is positioned in the non-restricted position) while storing the magazine 32 in the stocker 31, the rod member 52 is automatically positioned in the restricted position, so there is no risk of the component storage body 16 jumping out and falling out of the magazine 32 when the operator OP stores the magazine 32 in the stocker 31.

[0060] As described above, the tray feeder 13 provided in the component mounting device 1 in this embodiment includes the magazine 32 that holds the component storage units 16 so that they can be freely inserted and removed through the entrance 32F, and the stocker 31 having the storage space 31S that stores the magazine 32. The magazine 32 includes the rod member 52 as a drop prevention unit that is movable between a restricted position that restricts the insertion and removal of the component storage units 16 through the entrance 32F and an unrestricted position that allows the component storage units 16 to be inserted and removed through the entrance 32F, and the locking means 60 that locks the rod member 52 in the unrestricted position. Therefore, by locking the rod member 52 in the unrestricted position with the locking means 60, the operator OP does not need to manually hold the rod member 52 in the unrestricted position when inserting or removing the component storage units 16 into or from the magazine 32. Therefore, the operator OP can handle the component storage body 16 with both hands, which not only makes it easier to take the component storage body 16 in and out of the magazine 32, but also allows the operator OP to handle the component storage body 16 carefully, making it less likely that a mistake such as dropping a component BH from the component storage body 16 will occur.

[0061] Furthermore, in the tray feeder 13 of this embodiment, the stocker 31 is provided with a lock release means 70, and in the process of storing the magazine 32 in the storage space 31S of the stocker 31, the lock release means 70 releases the rod member 52 from the non-restricted position locked by the lock means 60. Therefore, even if the operator OP forgets to release the lock on the rod member 52 from the non-restricted position when storing the magazine 32 in the stocker 31, the rod member 52 automatically and reliably returns to the restricted position, preventing the component storage unit 16 from jumping out and falling out of the magazine 32.

[0062] In this way, according to the tray feeder 13 (component mounting device 1 equipped with tray feeder 13) in this embodiment, the rod member 52 can prevent the component storage body 16 from popping out, while improving workability when storing the magazine 32 in the stocker 31.

[0063] While the present invention has been described above in terms of an embodiment, it is not limited to the above and various modifications are possible. For example, in the above embodiment, the component storage unit 16 is composed of a tray TR having a plurality of pockets PK arranged in a matrix and a dish-shaped pallet PL on which the tray TR is placed. However, the component storage unit 16 only needs to be able to store components BH, and the tray TR does not necessarily have to have pockets PK. Alternatively, the tray TR and pallet PL may be integrally formed (i.e., the pockets PK are formed on the pallet PL).

[0064] The configuration of the fall-off prevention unit is not limited to that shown in the above embodiment as long as it is movable between a restricting position that restricts insertion and removal of the component storage unit 16 through the entrance 32F of the magazine 32 and a non-restricting position that allows insertion and removal of the component storage unit 16 through the entrance 32F. The locking means 60 may be configured to lock the fall-off prevention unit in the non-restricting position, and the unlocking means 70 may be configured to release the fall-off prevention unit from the state locked by the locking means 60 in the non-restricting position during the process of storing the magazine 32 in the storage space 31S of the stocker 31.
