Description

[Technical Field]

[0001] The present disclosure relates to a component stock device and a component mounting device. [Background technology]

[0002] Patent Document 1 discloses a component supply device that loads a magazine, which contains multiple trays containing aligned components separated into upper and lower trays, onto a lifting platform in a cabinet through a magazine loading / unloading opening with a door. This component supply device secures the magazine in the loading position by pressing it down with a retainer, and positions a specific tray in the magazine at the tray loading / unloading position of the cabinet by raising and lowering the lifting platform, and then pulls out the tray to make the stored components available for use. The component supply device also performs a component supply operation when a detection means detects that the door is in the closed position. The door cannot be closed when the retainer is not in the pressing position. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-068384 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a component supply device such as that described in Patent Document 1, due to the door opening / closing mechanism, a gap must be secured between the door and the magazine to be inserted into the cabinet of the component supply device when the door is closed. For this reason, the door may close even when the clamp is in a half-locked state (i.e., the magazine is not fully inserted) while approaching the clamping position. In this case, the detection means detects the door being closed, so there is a possibility that the component supply device may start operation (for example, supplying a tray from the magazine to a component mounting device) for the magazine that is not fully inserted.

[0005] The present disclosure has been devised in consideration of the above-described conventional situation, and aims to provide a component stock device and a component mounting device that can prevent the occurrence of a situation in which the magazine is incompletely inserted and can start operation only after the magazine is completely inserted. [Means for solving the problem]

[0006] The present disclosure provides a parts stock device comprising: a stocker that stores a magazine at a predetermined position in an internal space, the magazine having a removably insertable part storage body for storing parts; a magazine transport means that moves the magazine between the outside and the internal space by advancing to and retreating from the outside of the stocker through an opening formed in the stocker; a door that closes the opening with a gap between it and the magazine transport means when the magazine is located at the predetermined position; an opening closure detection unit that detects the door when the opening is closed; a restriction means that restricts the transport of the magazine to the predetermined position when the magazine is located at a restriction position that is closer to the opening than the predetermined position; and a switching means that releases the restriction of the restriction means to allow the magazine to move to the predetermined position and locks the movement of the magazine transport means with the magazine located at the predetermined position.

[0007] The present disclosure provides a component mounting device comprising a component stock device, a component storage drawer section that draws out the component storage body from the magazine housed in the internal space of the component stock device, and a mounting head that picks up the component from the component storage body drawn out by the component storage drawer section and mounts the component on a board. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to prevent the magazine from being incompletely inserted, and to start operation after the magazine is completely inserted. [Brief explanation of the drawings]

[0010] Hereinafter, with reference to the accompanying drawings, detailed descriptions of specific embodiments of the component stock device and component mounting device according to the present disclosure will be provided. However, unnecessary detailed descriptions 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.

[0011] FIG. 1 is a side view of a component mounting apparatus 11. The component mounting apparatus 11 is an example of a component mounting apparatus according to the present disclosure, and is an apparatus that produces mounted boards by picking up components BH from a tray TR supplied to a predetermined component supply position and mounting them on a board KB. In addition to a base 13, the component mounting apparatus 11 includes various devices, such as a transport conveyor 15, a component stock device 17, a mounting head 19, and a head moving mechanism 21. In the following description, the left-right direction as seen from the operator OP in FIG. 1 is defined as the X-axis direction, and the front-to-back direction as seen from the operator OP is defined as the Y-axis direction. The up-down direction perpendicular to both the X-axis and Y-axis directions is defined as the Z-axis direction. Furthermore, in the Y-axis direction, the far side as seen from the operator OP is defined as the front, and the near side is defined as the rear.

[0012] The transport conveyor 15 is provided on the upper surface of the base 13, and transports the board KB in the X-axis direction and positions it at a predetermined work position. The component stock device 17 is a component supply device for supplying components BH to the component mounting device 11. The component stock device 17 vertically stores magazines 23 that store multiple component storage bodies (e.g., pallets PL) that hold trays TR for component supply, and supplies the components BH by pulling out the required pallet PL and positioning it at a predetermined component supply height.

[0013] 1, the mounting head 19 has suction nozzles 25 at its lower end that pick up components BH. The mounting head 19 can generate a force at the lower end of each suction nozzle 25 that picks up components BH in the tray TR. The head movement mechanism 21 moves the mounting head 19 between the pallet PL, which has been positioned at the component supply height by the component stock device 17, and the board KB, which has been positioned by the transport conveyor 15.

[0014] Fig. 2 is a perspective view of the component stock device 17 provided in the component mounting device 11. Fig. 3 is a perspective side view of the component stock device 17. The component stock device 17 may be provided as a device that constitutes a part of the component mounting device 11, or may be provided as a device separate from the component mounting device 11. In the following description, the component stock device 17 will be described as being provided as a device that constitutes a part of the component mounting device 11.

[0015] 2 and 3, component stock device 17 includes cart 27, stocker 29, magazine 23, component storage unit drawer (pallet drawer 31), and lifting mechanism 33. Cart 27 is movable on the floor by a plurality of casters 35 and is moved by an operator OP. When component mounting device 11 is in operation, component stock device 17 is installed at a rear position of base 13 (see FIG. 1).

[0016] 2 and 3, the stocker 29 is attached to the rear of the cart 27. A plurality of magazine installation shelves 39 are arranged one above the other in the internal space 37 of the stocker 29. On each magazine installation shelf 39, one magazine 23 is installed at a predetermined position.

[0017] 2, an opening (for example, a magazine entrance 41) is formed on one side of stocker 29. Magazine entrance 41 is used as an entrance for installing magazine 23 on magazine installation shelf 39. Pallet drawer 31 is located in front of stocker 29. Pallet drawer 31 can be raised and lowered freely by lifting mechanism 33.

[0018] 4(a) and (b) are perspective views of the magazine 23 provided in the parts stock device 17. As shown in FIGS. 4(a) and (b), the magazine 23 has left and right side panels 43, a top panel 45, and a bottom panel 47 arranged opposite each other in the X-axis direction, and has an overall box shape that is open at both the front and back. The magazine 23 has a plurality of slots 49 arranged vertically inside (see FIG. 4(a)), and a pallet PL is inserted into each slot 49 one by one in a horizontal position and stored therein. This allows each pallet PL to be inserted into and removed from the magazine 23 horizontally. Wheels 51 are provided at each of the four corners of the underside of the magazine 23 (the underside of the bottom panel 47) to enable the magazine 23 to be easily moved.

[0019] Figure 5 is a perspective view of a portion of the component stock device 17. In Figures 4(b) and 5, the pallet PL has a dish shape, and the tray TR is placed on the upper surface of the pallet PL. The tray TR has a plurality of pockets PK arranged in a matrix (see Figure 5), and each pocket PK stores one component BH. The tray TR is positioned by being fixed to the upper surface of the pallet PL with a fixture KG such as a magnet. A pair of engaging blocks BL are provided on the front edge of the pallet PL, facing each other in the left-right direction (X-axis direction).

[0020] In Figure 5, pallet pull-out section 31 has a table section 53, a locking device 55, and a pair of pallet guides 57. Locking device 55 is a rod-shaped member extending in the X-axis direction, and is provided on table section 53 so as to be movable in the Y-axis direction (see arrow A in Figure 5). The pair of pallet guides 57 are provided on the top surface of table section 53 at positions sandwiching locking device 55 in the X-axis direction, and each has a shape that extends in the Y-axis direction.

[0021] 6(a) and (b) are explanatory diagrams of the operation of the parts stock device 17. When the pallet pull-out section 31 pulls out a pallet PL stored inside the magazine 23, it moves the locking device 55 rearward on the table section 53 (FIG. 5 → FIG. 6(a)), engages both ends of the locking device 55 with a pair of engaged blocks BL of the pallet PL (FIG. 6(a)), and then moves the locking device 55 forward (FIG. 6(a) → FIG. 6(b)). As a result, the pallet PL is pulled out of the magazine 23 and moves onto the table section 53. At this time, the pallet PL is guided on both sides by the left and right pallet guides 57, so that it is placed on the table section 53 in the correct position without tilting relative to the table section 53.

[0022] 2 and 3, the lifting mechanism 33 includes front and rear guide pillars 59 extending upward from the carriage 27, a ball screw 61 extending in the Z-axis direction, and a lifting motor 63 that drives the ball screw 61 to rotate about the Z-axis. The ball screw 61 is threadedly engaged with a nut portion 65 provided at the rear of the table portion 53 of the pallet drawer 31. The lifting motor 63 rotates the ball screw 61 about the Z-axis, thereby raising and lowering the table portion 53 (i.e., the pallet drawer 31) via the nut portion 65 (see arrow B in FIG. 3). At this time, the guide pillars 59 function as guides for movement of the table portion 53 in the Z-axis direction.

[0023] 1, the control device 67 provided in the component mounting device 11 performs overall control of the operation of each section of the component mounting device 11. Specifically, the control device 67 controls the transport of the board KB by the transport conveyor 15 and the positioning of the board KB at the work position. The control device 67 also controls the supply operation of the components BH by the component stock device 17. More specifically, the control device 67 controls the lifting operation of the pallet drawer 31 by the lifting mechanism 33, and the insertion and removal operation of the pallet PL from the magazine 23 by the pallet drawer 31. The control device 67 also controls the suction operation of the components BH by the mounting head 19, and the movement of the mounting head 19 by the head moving mechanism 21.

[0024] When the component mounting device 11 mounts components BH on a board KB, the control device 67 first operates the transport conveyor 15 to receive the board KB supplied from the upstream process side and position it at a predetermined position. After positioning the board KB, the control device 67 operates the lift motor 63 to move the pallet puller 31 to the height of the slot 49 in which the pallet PL to be pulled out is stored. Then, when the top surface of the table portion 53 is positioned at the height of the slot 49, the control device 67 moves the locking device 55 rearward (toward the magazine 23) and engages its left and right ends with a pair of engageable blocks BL provided on the pallet PL (see FIGS. 5 and 6(a)).

[0025] When the left and right ends of the locking device 55 engage with the engaged blocks BL of the pallet PL, the control device 67 moves the locking device 55 forward to place the pallet PL on the upper surface of the table unit 53 (see FIG. 6(a) → FIG. 6(b)). Once the pallet PL is placed on the upper surface of the table unit 53, the control device 67 activates the lifting motor 63 to position the table unit 53 at the component supply height (see FIGS. 1 and 2). Once the table unit 53 is positioned at the component supply height, the control device 67 enables the mounting head 19 to pick up the components BH stored on the pallet PL.

[0026] When the mounting head 19 is ready to pick up a component BH stored on the pallet PL, the control device 67 moves the mounting head 19 to repeatedly execute a mounting turn consisting of a pickup operation and a component mounting operation. Here, the pickup operation is the operation of suctioning the component BH supplied by the component stock device 17 onto the suction nozzle 25, and the component mounting operation is the operation of mounting the component BH that has been picked up by the suction nozzle 25 during the pickup operation onto the board KB. After the control device 67 has repeatedly executed the mounting turn to mount all of the components BH that should be mounted on the board KB, it operates the transport conveyor 15 to transport the board KB to the downstream process side. This completes the component mounting operation for one board KB.

[0027] 7 is a perspective side view of a stocker 29 provided in the component stock device 17 of the component mounting device 11. Rails 69 are attached to each magazine installation shelf 39 provided in the stocker 29. One magazine 23 is installed on each magazine installation shelf 39 via the rails 69. The rails 69 can advance to an outside 71 through a magazine entrance 41 formed on one side of the stocker 29. The rails 69 can advance to and retreat from the internal space 37 of the stocker 29 to the outside 71 via the magazine entrance 41.

[0028] Rail section 69 is provided extending in the X-axis direction within internal space 37 of stocker 29. Rail section 69 is made up of a pair of nested rails (telescopic rails) arranged side by side in the Y-axis direction, and has a base rail 73 fixed to stocker 29 and a slide rail 75 that slides relative to base rail 73.

[0029] The base rail 73 is entirely housed in the internal space 37 of the stocker 29. The slide rail 75 can move (slide) between a position where it is entirely housed in the internal space 37 of the stocker 29 and a position where it advances to the outside 71 of the stocker 29 through the magazine entrance 41.

[0030] A magazine mounting portion 77, which is a mounting portion for magazine 23, is provided on the pair of slide rails 75 so as to be slidable laterally (in the X-axis direction, approximately horizontally). The rail portion 69 and the magazine mounting portion 77 constitute a magazine transport means 79. By the rail portion 69 moving forward and backward through the magazine entrance 41, the magazine mounting portion 77 can move between a position housed in the internal space 37 of the stocker 29 and a position drawn out to the outside 71 of the stocker 29.

[0031] Two holding portions 81 extending in the Y-axis direction are arranged side by side in the X-axis direction on the upper surface of the magazine mounting portion 77. The two holding portions 81 have stepped portions on which the corners where the bottom and side surfaces of the magazine 23 intersect are placed. These two holding portions 81 are arranged with their stepped portions facing each other, thereby sandwiching and holding the magazine 23 in the X-axis direction. The holding portions 81 function as movement restriction portions that restrict movement of the magazine 23 placed on the magazine mounting portion 77.

[0032] A base end of a placement section stopper 85 is attached to a wall section 83 that is a part of the stocker 29. The tip end of the placement section stopper 85 faces the magazine entrance 41. The placement section stopper 85 is movable in the X-axis direction, and is biased toward the magazine entrance 41 by a return spring 87. Therefore, when the placement section stopper 85 receives a pressing force from the magazine placement section 77 due to the retraction of the rail section 69, it compresses the return spring 87 and moves in a direction away from the magazine entrance 41 (a direction approaching the wall section 83) until it reaches a set movement limit.

[0033] The base end of a magazine biasing spring 89, which is a biasing member, is attached to the wall 83 above the placement section stopper 85. The tip (free end) of the magazine biasing spring 89 faces the magazine entrance 41. The magazine biasing spring 89 is made of a compression spring. As the magazine 23 is pushed into the internal space 37 of the stocker 29, it abuts against the tip (free end) of the magazine biasing spring 89 and compresses the magazine biasing spring 89. This causes the magazine biasing spring 89 to generate a biasing force that presses (pushes back) the magazine 23 in a direction toward the magazine entrance 41. The magazine 23 pushed back by the magazine biasing spring 89 abuts against the holder 81 on the magazine entrance 41 side, thereby restricting rattling in the X direction with respect to the magazine placement section 77.

[0034] The base end of a bracket 91 is fixed to the wall 83 between the placement section stopper 85 and the magazine installation shelf 39. The bracket 91 extends along each rail 69, with its tip end protruding toward the magazine entrance 41. A restricting means 93 is provided across the tip of the bracket 91 in the protruding direction and the tip of the magazine placement section 77 in the advancing direction. In addition, a switching means 95 is provided at the tip of the magazine placement section 77 in the advancing direction.

[0035] 8 is an enlarged view of the main parts of the regulating means 93 and the switching means 95 when the magazine 23 is positioned at a predetermined position in the internal space 37. The magazine entrance 41 described above is formed in an outer shell 97, which is part of the stocker 29, on the opposite side of the magazine 23 from the wall 83. A door 99 that can freely open and close the magazine entrance 41 is attached to the outer shell 97. The door 99 closes the magazine entrance 41 by abutting against a door stop 101 attached to the outer shell 97, and reaches the final closed position C.

[0036] In the internal space 37, a sensor bracket 103 fixed to the outer shell portion 97 is disposed near the magazine entrance 41. An opening closure detection unit 105 is attached to the sensor bracket 103, and detects the door 99 that has closed the magazine entrance 41. The opening closure detection unit 105 detects the door 99 that has closed the magazine entrance 41 and reached the final closed position C. The opening closure detection unit 105 has, for example, a pair of separation and opening joints (not shown) in a groove, and when a conductive key KE provided on the door 99 is inserted into the groove, the pair of separation and opening joints are closed, and the door 99 is detected to have reached the final closed position C. Note that the configuration of the opening closure detection unit 105 is not limited to this as long as it can detect a closed door 99.

[0037] 9 is an enlarged view of the essential parts of the parts stock device 17, with the magazine transport means 79 restricted by the restricting means 93 when the magazine 23 is not inserted. The restricting means 93 restricts the magazine 23 from being transported to the predetermined position when the magazine 23 is in a restricted position closer to the opening than the predetermined position. The restricting means 93 includes a first engaging portion 107 and a second engaging portion 109. The first engaging portion 107 is disposed below the mounting portion and protrudes downward. The second engaging portion 109 is disposed at the protruding tip of the bracket 91 and protrudes upward toward the magazine mounting portion 77 to engage with the first engaging portion 107.

[0038] In this embodiment, the switching means 95 is, for example, a lock lever 111. The lock lever 111 extends in the X-axis direction along the magazine placement portion 77 and is swingable about a swing shaft 113 that is in the horizontal direction (i.e., the Y-axis direction) that intersects with the transport direction of the magazine 23. One end of the lock lever 111 (the end on the magazine entrance / exit side) that sandwiches the swing shaft 113 swings about the swing shaft 113, and the other end also swings.

[0039] The lock lever 111 has a knob 115 at one end. A handle 117 extending from the magazine mounting portion 77 is disposed below the knob 115 at a distance. The lock lever 111 can be swung by, for example, an operator OP holding the handle 117 with one hand and pressing the knob 115 with a finger. The other end of the lock lever 111 is urged downward in FIG. 9 by a lever biasing spring 119. That is, the lock lever 111 is urged clockwise around the swing shaft 113. The lock lever 111, urged by the lever biasing spring 119, is stopped at a horizontal position by a lever stopper (not shown). Therefore, when the knob 115 is pressed down, the lock lever 111 swung counterclockwise against the biasing force of the lever biasing spring 119.

[0040] The lock lever 111 has a first engagement portion 107 that protrudes downward at the other end. The lock lever 111 can move the first engagement portion 107 between two positions: a first position where the first engagement portion 107 engages with the second engagement portion 109 on the opening side, and a second position where the first engagement portion 107 does not engage with the second engagement portion 109 on the opening side. In other words, the lock lever 111 can be moved to the second position where the first engagement portion 107 does not engage with the second engagement portion 109 on the opening side by swinging the knob portion 115. When the first engagement portion 107 is in the second position, the lock lever 111 allows the magazine 23 to be transported from the restricted position to a predetermined position.

[0041] When the magazine 23 of the parts stock device 17 is in the restricted position shown in Figure 9, the door 99 is prevented from closing against the magazine entrance 41 by the lock lever 111 (knob portion or handle portion 117) abutting against the inside of the door 99.

[0042] By the swinging of the gripping portion 115, the magazine conveying means 79 permitted to move is pushed by the handle portion 117 and moved to the inner side of the inner space 37. When the magazine 23 reaches a predetermined position, the lock lever 111 is swung clockwise in FIG. 8 by the biasing force of the lever biasing spring 119 when the finger is released from the gripping portion 115, and the first engaging portion 107 abuts against the second engaging portion 109 from the opposite side of the magazine entrance / exit 41.

[0043] In this state, the magazine 23 is biased substantially horizontally by the magazine biasing spring 89. The first engaging portion 107 is pressed against the second engaging portion 109 in a direction opposite to the conveying direction of the magazine 23 from the outside 71 to the inner space 37. Thereby, as shown in FIG. 8, the movement of the magazine conveying means 79 is locked (positioned) by the lock lever 111 in the component stock device 17.

[0044] FIG. 10 is an enlarged view of the main part of the regulating means 93 and the switching means 95. The sum (T + U) of the respective distances (length or width) T and U of the first engaging portion 107 and the second engaging portion 109 in the conveying direction (X-axis direction) of the magazine 23 from the outside 71 (for example, see FIG. 7) to the inner space 37 is larger than the distance of the gap S (S < T + U). Thereby, as shown in FIG. 9, the switching means 95 can regulate the closing of the door 99 when the first engaging portion 107 abuts against the second engaging portion 109 from the side of the magazine entrance / exit 41.

[0045] FIG. 11 is a perspective view of a main part showing the biasing structure of the second engagement portion 109. The second engagement portion 109 is biased in the direction opposite to the transport direction of the magazine 23 from the exterior 71 to the internal space 37. The second engagement portion 109 has a shaft member 121 (see FIG. 10) extending along the Y-axis direction. An outer cylindrical member 123 that contacts the first engagement portion 107 is rotatably fitted around the outer periphery of this shaft member 121. In other words, when the second engagement portion 109 engages or disengages with the first engagement portion 107, the outer cylindrical member 123 rotates, enabling low-friction contact. Both ends of the shaft member 121 are supported by support brackets 127, which are made up of a pair of parallel support plates 125. The support brackets 127 are fixed to the bracket 91. Each support plate 125 has an elongated hole 129 that is long in the X-axis direction. Both ends of the shaft member 121 of the second engaging portion 109 pass through the elongated hole 129 and are supported so as to be movable in the longitudinal direction of the elongated hole 129. In the second engaging portion 109, an outer cylinder member 123 fitted onto the shaft member 121 is disposed between a pair of support plates 125 such that its movement in the axial direction is restricted.

[0046] Movable-side L-shaped brackets 131 are fixed to both ends of the shaft member 121 that passes through the elongated hole 129. A guide shaft 133 extending in the longitudinal direction of the elongated hole 129 (the X-axis direction) passes through each movable-side L-shaped bracket 131 so as to be able to slide. The guide shafts 133 are supported by fixed-side L-shaped brackets 135 that are fixed to each support plate 125. A coil-shaped stopper biasing spring 137 is fitted around the guide shaft 133 between the movable-side L-shaped bracket 131 and the fixed-side L-shaped bracket 135. The stopper biasing spring 137 biases the movable-side L-shaped bracket 131 toward the magazine entrance / exit side, thereby biasing the second engagement portion 109 in the same direction. The second engagement portion 109, biased in the X-axis direction, stops when the shaft member 121 hits the end of the elongated hole 129. When the second engagement portion 109 is in this stop position, the first engagement portion 107 engages with the magazine entrance 41 from the opposite side, thereby restricting movement of the magazine transport means 79 in the X-axis direction and positioning the magazine 23 at a predetermined position.

[0047] Next, the operation of the parts stock device 17 will be described.

[0048] 12 is an explanatory diagram of the operation when the first engagement portion 107 is in the first position. When the magazine transport means 79 retreats and the lock lever 111 enters the internal space 37 without swinging, the first engagement portion 107 provided at the other end of the lock lever 111 is in the first position where it abuts against the second engagement portion 109. At this time, the magazine 23 is in the restricted position. When the first engagement portion 107 is in the first position, one end (such as the knob 115) of the lock lever 111 protrudes toward the outside 71 beyond the magazine entrance 41, thereby interfering with the door 99 that is being closed and preventing the door 99 from closing the magazine entrance 41. Therefore, when the magazine 23 is in the restricted position, the opening closure detection unit 105 is not turned on.

[0049] 13 is an explanatory diagram of the operation when the lock lever 111 is swung. When the knob 115 at one end of the lock lever 111, with the first engagement portion 107 in the first position, is operated, the lock lever 111 moves to a second position where the first engagement portion 107 does not engage with the second engagement portion 109 on the opening side. When the first engagement portion 107 is in the second position, the lock lever 111 allows the magazine 23 to be transported from the restricted position to a predetermined position.

[0050] 14 is an explanatory diagram of the operation when the first engagement portion 107 is in the middle of climbing over the second engagement portion 109. When the magazine transport means 79, with the first engagement portion 107 of the lock lever 111 in the second position, is pushed further into the internal space 37, the first engagement portion 107 slides over the second engagement portion 109 while making sliding contact with the outer cylindrical member 123 (see FIG. 9). At this time, the lever biasing spring 119, which biases the lock lever 111 clockwise in FIG. 14, is compressed and an elastic restoring force is accumulated.

[0051] 15 is an explanatory diagram of the operation immediately after the first engagement portion 107 passes over the second engagement portion 109. When the magazine 23 is pushed into a predetermined position, the first engagement portion 107 of the lock lever 111 passes over the second engagement portion 109. The lock lever 111 is then swung clockwise in FIG. 15 by the elastic restoring force of the lever biasing spring 119 that has accumulated. The swung lock lever 111 descends to a position where the first engagement portion 107 abuts against the second engagement portion 109 from the internal space side opposite the magazine entrance 41.

[0052] 16 is an explanatory diagram of the operation when the first engagement portion 107 abuts against the second engagement portion 109 from the internal space side opposite the magazine entrance 41, locking the magazine 23 in a predetermined position. When the first engagement portion 107 descends, the lock lever 111 abuts against the second engagement portion 109 from the internal space side. In this state, the magazine placement portion 77 of the magazine transport means 79 is biased toward the magazine entrance by the return spring 87 of the placement portion stopper 85. The magazine 23 is also biased toward the magazine entrance by the magazine biasing spring 89.

[0053] As a result, the magazine carrying means 79 positions the magazine placement section 77 as the first engagement section 107 abuts against the second engagement section 109. The magazine 23 is then positioned relative to the holder 81 of the positioned magazine placement section 77, and is locked in the predetermined position. With the magazine 23 in this predetermined position, the parts stock device 17 no longer prevents the door 99 from closing, and the door 99 abuts against the door stop 101 and is closed. As a result, the parts stock device 17 has the conductor key KE enter the groove of the opening closure detection section 105, turning on the opening closure detection section 105, and notifying the facility that the magazine 23 has been inserted normally.

[0054] Next, the operation of the parts stock device 17 will be described.

[0055] The parts stock device 17 includes a stocker 29 that stores a magazine 23 at a predetermined position in an internal space 37, the magazine 23 having removably insertable part storage bodies (e.g., pallets PL) for storing parts BH; a magazine transport means 79 that moves the magazine 23 between the outside 71 and the internal space 37 by advancing to and retreating from the outside 71 of the stocker 29 through an opening (e.g., a magazine entrance / exit 41) provided in the internal space 37; a door 99 provided in the stocker 29 that closes the opening with a gap S between it and the magazine transport means 79 when the magazine 23 is located at the predetermined position; an opening closure detection unit 105 that detects the door 99 when the opening is closed; a restriction means 93 that restricts the transport of the magazine 23 to the predetermined position when the magazine 23 is located at a restriction position that is closer to the opening than the predetermined position; and a switching means 95 that releases the restriction of the restriction means 93 to allow the magazine 23 to move to the predetermined position and locks the movement of the magazine transport means 79 when the magazine 23 reaches the predetermined position.

[0056] In parts stock device 17, magazine transport means 79 provided in internal space 37 of stocker 29 enables magazine 23 to be moved between internal space 37 of stocker 29 and outside 71 of stocker 29. Magazine transport means 79 advances to outside 71 and retreats to internal space 37 through an opening (for example, magazine entrance / exit 41) formed in stocker 29. Stocker 29 is provided with a door 99 that opens and closes magazine entrance / exit 41.

[0057] When the magazine 23 is at a predetermined position in the internal space 37, the door 99 closes the magazine entrance 41 with a gap S between it and the magazine transport means 79. In the parts stock device 17, due to manufacturing tolerances and assembly tolerances of each part, the magazine transport means 79, which has positioned the magazine 23 at a predetermined position, may slightly protrude into the magazine entrance 41. In this case, the door 99 may become unable to close if it interferes with the protruding magazine transport means 79. Therefore, by ensuring the above-mentioned gap S, the parts stock device 17 prevents the door 99 from becoming unnecessarily unable to close when the magazine transport means 79, which has been misaligned due to tolerances, interferes with the door 99 when the magazine 23 is positioned at a predetermined position.

[0058] Here, before describing the main functions of the parts stock device 17, we will explain the functions of a parts stock device 139 according to a comparative example. Figure 17 is an enlarged view of the main parts of the parts stock device 139 according to the comparative example, showing the closed state of the door 99 when the magazine 23 is placed in a predetermined position.

[0059] In parts stock device 139, when magazine 23 is placed in a predetermined position, lever 143, which is swingably supported by bracket 91, engages with stopper 141 provided on magazine transport means 79. At this time, magazine 23 is biased toward the magazine entrance / exit side by magazine biasing spring 89. Similarly, magazine transport means 79 is also biased toward the magazine entrance / exit side by return spring 87 (see FIG. 7) of placement section stopper 85. As a result, magazine 23 is placed in a locked state in which movement in the X direction is restricted, and it is positioned at a predetermined position.

[0060] At this time, even in the parts stock device 139 according to the comparative example, the door 99 is closed with a gap S secured between the magazine transport means 79 and the door 99. The closed door 99 cannot be closed any further because it abuts against the door stop 101. In other words, the door 99 is in the final closed position C. For this reason, the magazine 23 cannot be pushed in through the door 99. In this closed state, the door 99 is detected as closed by the opening closure detection unit 105.

[0061] 18 is an enlarged view of a main portion of a parts stock device 139 according to a comparative example, showing the closed state of the door 99 when the magazine 23 is incompletely inserted. However, in the parts stock device 139 according to the comparative example, the gap S can cause the lever 143 to enter a half-locked state. That is, even if the lever 143 is in a half-locked state where it is not fully engaged with the stopper 141, if the door 99 is forcibly closed, the gap S will cause the door 99 to close while the magazine 23 remains in an incompletely inserted state. In other words, the door 99 reaches the final closed position C. Once the door 99 is closed, the opening / closing detection unit 105 will detect that the door 99 is closed, and there is a possibility that the equipment will start operating even though the magazine 23 is in an incompletely inserted state.

[0062] Therefore, in the parts stocking device 17 according to this embodiment, the stocker 29 is provided with a restricting means 93. The restricting means 93 restricts the movement of the magazine transporting means 79 when the magazine 23 is at the opening side position before it reaches the predetermined position (i.e., when the magazine 23 is not inserted), as shown in FIG. 9 . In other words, the magazine 23 is actively in an uninserted state. When the magazine 23 is not inserted in the stocker 29, the restricting means 93 restricts the movement of the magazine transporting means 79, causing the magazine transporting means 79 to protrude toward the opening. This causes interference with the magazine transporting means 79, making it impossible to close the door 99. Therefore, the opening closure detector 105 does not detect that the door 99 is closed (does not turn ON), because the door 99 is not closed.

[0063] The stocker 29 is also provided with a switching means 95. The switching means 95 releases the restriction imposed by the restricting means 93 and allows the movement of the uninserted magazine 23 to a predetermined position. In addition, the switching means 95 locks the movement of the magazine transport means 79 when the magazine 23 reaches the predetermined position.

[0064] Therefore, in the parts stock device 17, the movement of the magazine transport means 79 is restricted by the restricting means 93 when the magazine 23 is in an incompletely inserted state before it reaches the predetermined position, so the door 99 does not close. This prevents the magazine 23 from being in an incompletely inserted state. As a result, the parts stock device 17 can reliably prevent the opening closure detection unit 105 from turning ON and the equipment from starting operation while the magazine 23 is in an incompletely inserted state. In other words, the parts stock device 17 prevents the magazine 23 from being incompletely inserted and can start operation only after the magazine 23 is completely inserted.

[0065] Furthermore, in parts stock device 17, magazine transport means 79 includes a mounting portion (e.g., magazine mounting portion 77) on which magazine 23 is mounted. Restriction means 93 includes a first engagement portion 107 that is provided below the mounting portion and protrudes downward, and a second engagement portion 109 that is provided in internal space 37 and protrudes upward toward the mounting portion and engages with first engagement portion 107. Switching means 95 moves first engagement portion 107 between two positions: a first position where first engagement portion 107 engages with second engagement portion 109 on the opening side, and a second position where first engagement portion 107 does not engage with second engagement portion 109 on the opening side; and when first engagement portion 107 is located in the second position, permits magazine 23 to be transported from the restricted position to a predetermined position.

[0066] In this parts stock device 17, the magazine transport means 79 includes a magazine placement portion 77. The restriction means 93 includes a first engagement portion 107 and a second engagement portion 109. The first engagement portion 107 is provided below the placement portion and protrudes downward. The second engagement portion 109 is provided in the internal space 37 and protrudes upward toward the magazine placement portion 77.

[0067] The switching means 95 moves the first engagement portion 107 between two positions, a first position and a second position. At the first position, the first engagement portion 107 engages with the second engagement portion 109 on the opening side. At the second position, the first engagement portion 107 does not engage with the second engagement portion 109 on the opening side. When the first engagement portion 107 is located at the second position, the switching means 95 allows the magazine 23 to be transported from the restricted position to the predetermined position. In other words, the switching means 95 can release the restriction on movement of the magazine transport means 79 so that the magazine 23 can be transported from the restricted position to the predetermined position.

[0068] The parts stock device 17 further includes a lock lever 111 that is provided on the mounting section and is swingable around a direction intersecting the conveying direction of the magazine 23, with one end swinging around the swing center and the other end also swinging. The first engagement portion 107 is provided on the other end of the lock lever 111. The switching means is constituted by the lock lever 111 that swings one end to swing the other end to move the first engagement portion 107 to a second position where it does not engage with the second engagement portion 109 on the opening side.

[0069] In this parts stock device 17, the switching means 95 is a lock lever 111. The lock lever 111 is provided below the magazine mounting portion 77 and protrudes downward. The lock lever 111 extends along the transport direction of the magazine 23, and the center of the extension direction is capable of swinging about a horizontal swing center that intersects with the transport direction of the magazine 23.

[0070] When one end of the lock lever 111, which is on the magazine entrance side, is swung around the swing center, the other end is also swung. In other words, one end of the lock lever 111 can be used as a knob 115 on the operation side. The first engagement portion 107 is provided on the other end of this lock lever 111. When the knob 115 is swung, the first engagement portion 107 is swung, and the lock lever 111 can be moved to a second position where the first engagement portion 107 does not engage with the second engagement portion 109 on the opening side.

[0071] As a result, the magazine transport means 79 is released from the movement restriction imposed on the magazine 23 before it reaches the predetermined position and before it is inserted. With the movement restriction now released, the magazine transport means 79 is able to insert the magazine 23 into the predetermined position. When the magazine 23 reaches the predetermined position, the first engagement portion 107 of the magazine transport means 79 moves over the second engagement portion 109, and the first engagement portion 107 is positioned in a locked position on the opposite side of the second engagement portion 109 from the first position. With the first engagement portion 107 positioned in the locked position, the magazine transport means 79 is locked from moving with the magazine 23 positioned in the predetermined position.

[0072] Furthermore, in the parts stock device 17, when the magazine 23 is in the restricted position, the lock lever 111 abutting against the door 99 prevents the door 99 from closing against the opening.

[0073] In this parts stock device 17, when the magazine 23 is in the restricted position, the magazine transport means 79 protrudes toward the magazine entrance. A lock lever 111 is provided on the magazine entrance side of the magazine transport means 79. When the magazine 23 is in the restricted position, the first engagement portion 107 provided on the lock lever 111 engages with the second engagement portion 109 provided in the internal space 37 on the magazine entrance side. In other words, the knob portion 115 provided on one end of the lock lever 111 protrudes toward the magazine entrance side by the distance of the first engagement portion 107 and the second engagement portion 109 along the insertion direction of the magazine 23. As a result, as shown in FIG. 18 , the door 99 abuts against the lock lever 111 provided on the magazine transport means 79, whose movement is restricted, and is prevented from closing the magazine entrance 41.

[0074] In the parts stock device 17, the total length of the first engagement portion 107 and the second engagement portion 109 in the conveyance direction of the magazine 23 from the outside 71 to the internal space 37 is greater than the distance of the gap.

[0075] In this parts stock device 17, the gap between the magazine transport means 79, which has placed the magazine 23 at a predetermined position, and the door 99 has a predetermined size relationship with the dimensions of the first engagement portion 107 and the second engagement portion 109. That is, the first engagement portion 107 and the second engagement portion 109 are set so that the sum of their respective distances in the transport direction of the magazine 23 from the outside 71 to the internal space 37 is greater than the distance of the gap. More specifically, when the distance (length or width) of the first engagement portion 107 in the magazine transport direction is T, the distance (length or width) of the second engagement portion 109 in the magazine transport direction is U, and the gap is S, then S <T+Uとなっている。

[0076] As a result, by ensuring gap S, parts stock device 17 can prevent magazine transport means 79, which has shifted in position due to tolerance, from interfering with door 99 when magazine 23 is in the predetermined position, causing door 99 to become unnecessarily unable to close. In addition, when magazine 23 is in an uninserted state before reaching the predetermined position, first engagement portion 107 and second engagement portion 109 restrict the movement of magazine transport means 79, preventing door 99 from closing. This effectively prevents magazine 23 from becoming incompletely inserted.

[0077] In addition, in the parts stock device 17, the second engagement portion 109 is biased in a direction opposite to the conveyance direction of the magazine 23 from the outside 71 to the internal space 37.

[0078] In this parts stock device 17, the second engagement portion 109 is biased in a direction opposite to the transport direction of the magazine 23 from the outside 71 to the internal space 37. When the magazine transport means 79 with the magazine 23 placed thereon is pushed into the internal space 37 in the normal state where the switching means 95 is not swung, the first engagement portion 107 provided on the switching means 95 comes into contact with the second engagement portion 109 provided in the internal space 37.

[0079] Therefore, when the magazine transport means 79 is forcefully pushed into the internal space 37, the first engagement portion 107 comes into contact with the second engagement portion 109. At this time, the second engagement portion 109 is biased in the direction opposite to the transport direction of the magazine 23, so it moves in the transport direction of the magazine 23 against this biasing force, absorbing part of the impact energy and reducing the reaction force that the first engagement portion 107 receives from the second engagement portion 109.

[0080] As a result, the first engagement portion 107 of the magazine transport means 79 comes into contact with the second engagement portion 109, and the impact acting on the magazine 23 via the switching means 95 and the magazine placement portion 77 is alleviated. As a result, the parts stock device 17 can prevent the parts in the magazine from scattering due to the impact from the second engagement portion 109 when the magazine 23 is pushed in.

[0081] In addition, the parts stock device 17 further has a biasing member (magazine biasing spring 89) that is provided in the internal space 37 and biases the magazine 23 at a predetermined position approximately horizontally, pressing the first engagement portion 107 against the second engagement portion 109 in a direction opposite to the transport direction of the magazine 23 from the outside 71 to the internal space 37.

[0082] In this parts stock device 17, the magazine 23 in a predetermined position is urged almost horizontally by a urging member (magazine urging spring 89) provided in the internal space 37. The almost horizontal urging direction of this magazine urging spring 89 is opposite to the direction in which the magazine 23 is transported from the outside 71 to the internal space 37.

[0083] The magazine 23 is urged by the magazine urging spring 89 in the direction opposite to the magazine transport direction, and the magazine transport means 79 is urged in the same direction via the magazine 23. That is, the magazine transport means 79 urges the magazine placement portion 77 in the same direction via the magazine 23, and the first engagement portion 107 of the switching means 95 provided on the magazine placement portion 77 is pressed against the second engagement portion 109 from the side opposite to the magazine entrance 41 (see FIG. 8).

[0084] As a result, the magazine transport means 79 is positioned such that the magazine placement portion 77 is biased relative to the position of the second engagement portion 109 with which the first engagement portion 107 abuts. In addition, the magazine 23 is also positioned by being pressed against the magazine entrance / exit side of the holding portion 81 of the positioned magazine placement portion 77. As a result, the magazine 23 is positioned at a predetermined position relative to the second engagement portion 109.

[0085] 19 is an enlarged view of a main portion of the component stock device 17 according to the first embodiment, in which a biasing force acts on the magazine 23 in a push-back direction when the magazine is not completely inserted. In the component stock device 17, when the magazine is not completely inserted (e.g., in a semi-locked state), the magazine biasing spring 89 pushes the magazine 23 back in the direction of arrow D. In the semi-locked state, the first engagement portion 107 rides up on the second engagement portion 109. At this time, the lock lever 111 is biased by the lever biasing spring 119 in a direction in which the first engagement portion 107 presses down on the cylindrical second engagement portion 109 from above.

[0086] In this state, when the hands are released from the knob portion 115 and the handle portion 117 and the door 99 is about to be closed, the magazine transport means 79, which is no longer subjected to a pushing force, is pushed back in the direction of arrow D via the magazine 23 which is biased by the magazine biasing spring 89.

[0087] 20 is an enlarged view of a main portion of parts stock device 17 according to embodiment 1 in which magazine 23 is pushed back while it is not completely inserted, causing first engagement portion 107 to assume the first position. When magazine transport means 79 is pushed back, first engagement portion 107, which had been resting on second engagement portion 109, moves toward the magazine entrance / exit side. Then, lock lever 111 is pushed down in the direction of arrow E by the biasing force of lever biasing spring 119, and first engagement portion 107 assumes the first position where it abuts against second engagement portion 109 on the magazine entrance / exit side.

[0088] 9, the first engagement portion 107 of the door 99 comes into contact with the second engagement portion 109, making it impossible to close the door 99. That is, the component stock device 17 according to the first embodiment can effectively prevent the door 99 from being closed in a semi-locked state (an incomplete insertion state occurring when the door 99 is forcibly closed), as in the component stock device 139 of the comparative example shown in FIG.

[0089] In addition, the component mounting device 11 according to embodiment 1 includes a component stock device 17, a component storage body drawer that draws out a component storage body from a magazine 23 housed in the internal space 37 of the component stock device 17, and a mounting head 19 that picks up a component from the component storage body drawn out by the component storage body drawer and mounts the component on a board.

[0090] The component mounting device 11 according to the first embodiment includes a component stock device 17. In the component mounting device 11, a component storage drawer (pallet drawer 31) draws out a magazine 23 stored in an internal space 37 of the component stock device 17, and a mounting head 19 picks up a component from the drawn component storage and mounts it on a board.

[0091] At this time, the parts stock device 17 is provided with a restricting means 93 and a switching means 95, and thereby restricts the movement of the magazine transporting means 79 at the position on the opening side before the magazine 23 reaches the predetermined position (i.e., when the magazine 23 is not inserted). With the movement of the magazine transporting means 79 restricted, the parts stock device 17 is unable to close the door 99, and the opening closure detection unit 105, which operates when the door 99 is normally closed, does not operate.

[0092] Therefore, the component mounting device 11 does not start operation of the facility when the opening closure detector 105 is turned on while the magazine 23 is incompletely inserted.

[0093] This prevents the pallet drawer 31 from operating when the magazine 23 of the component stock device 17 is in a half-locked state on its way to the predetermined position, preventing the locking device 55 of the pallet drawer 31 from drawing out the engaged block BL of the pallet PL stored in the magazine 23 that is not in the predetermined position, which would cause a locking error. This prevents the component mounting device 11 from having to stop due to an error, thereby improving productivity.

[0094] Therefore, with the parts stock device 17 according to the first embodiment, it is possible to prevent the opening closure detection unit 105 from turning on and causing the equipment to operate when the magazine 23 is in an incompletely inserted state.

[0095] Furthermore, according to the component mounting device 11 of embodiment 1, it is possible to prevent the equipment from operating when the magazine 23 is incompletely inserted, thereby preventing operational errors from occurring, thereby reducing unnecessary error downtime and improving productivity.

[0096] Although various embodiments have been described above with reference to the accompanying drawings, the present disclosure is not limited to such examples. It is clear that those skilled in the art can conceive of various modifications, alterations, substitutions, additions, deletions, and equivalents within the scope of the claims, and it is understood that these also fall within the technical scope of the present disclosure. Furthermore, the components of the various embodiments described above may be combined in any manner without departing from the spirit of the invention. [Industrial Applicability]
