  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The configuration, shape, and the like described below are examples for explanation, and can be appropriately changed according to the specifications of the component mounting device and the component supply device (tray feeder). In the following, corresponding elements in all the drawings are denoted by the same reference numerals, and redundant description will be omitted. In FIG. 1 and a part to be described later, as two axial directions orthogonal to each other in a horizontal plane, an X direction in the substrate transport direction (horizontal direction in FIG. 1) and a Y direction orthogonal to the substrate transport direction (vertical direction in FIG. 1) Is shown. In FIG. 2 and a part described later, the Z direction is indicated as a height direction orthogonal to the horizontal plane. The Z direction is a vertical direction or an orthogonal direction when the component mounting apparatus is installed on a horizontal plane.

  First, the configuration of the component mounting apparatus 1 will be described with reference to FIG. In FIG. 1, a substrate transfer mechanism 2 is disposed on the upper surface of a base 1a in the X direction. The board transport mechanism 2 transports the board 3 on which components are to be mounted, and positions and holds the board 3 at a work position by the component mounting mechanism described below. Component supply units 4A and 4B for supplying components mounted on the substrate 3 are provided on both sides of the substrate transport mechanism 2.

  A component supply device 5 (tray feeder) is disposed in the component supply unit 4A. The component supply device 5 moves the pallet 7 on which the trays 6 (here, two) for storing the components P in a grid array to a component supply position for supplying the components P to a component mounting mechanism described below. A plurality of tape feeders 8 are arranged in parallel in the component supply unit 4B. The tape feeder 8 supplies the component P to the component mounting mechanism by feeding the carrier tape holding the component P at a pitch.

  A Y-axis beam 9 having a linear drive mechanism is disposed at one end in the X direction on the upper surface of the base 1a. To the Y-axis beam 9, two X-axis beams 10 similarly having a linear drive mechanism are movably coupled in the Y direction. A mounting head 11 is mounted on each of the two X-axis beams 10 so as to be movable in the X direction. The mounting head 11 is a multiple head including a plurality of holding heads, and a suction nozzle for sucking the component P is attached to a lower end of each holding head.

  By driving the Y-axis beam 9 and the X-axis beam 10, the mounting head 11 moves horizontally (X direction, Y direction) between the component supply units 4A, 4B and the substrate 3 held by the substrate transport mechanism 2. The component P supplied by the component supply units 4A and 4B is taken out by the suction nozzle and mounted on the board 3. Therefore, the Y-axis beam 9, the X-axis beam 10, and the mounting head 11 constitute a component mounting mechanism for mounting the component P on the substrate 3 by the suction nozzle.

  A component recognition camera 12 is provided between the component supply units 4A and 4B and the board transport mechanism 2. When the mounting head 11 that has taken out the component P from the component supply units 4A and 4B moves above the component recognition camera 12, the component recognition camera 12 captures an image of the component P held by the mounting head 11. Thereby, identification and position recognition of the component P held by the mounting head 11 are performed. The mounting head 11 is provided with a board recognition camera 13 located on the lower surface side of the X-axis beam 10 and moving integrally with the mounting head 11. When the mounting head 11 moves, the board recognition camera 13 moves above the board 3 positioned and held by the board transport mechanism 2 and captures an image of the board 3. Thus, the position of the substrate 3 is recognized.

  Next, the configuration of the component supply device 5 will be described with reference to FIGS. The component supply device 5 includes a carriage 20 that is movable on a work floor by wheels 21. On the upper surface of the cart unit 20, a rack unit 22 and a pallet moving unit 23 are provided. A plurality of (two in this case) magazine holding sections 24 for storing magazines 40 for stacking and storing the pallets 7 for mounting the trays 6 for storing the components P are arranged in the rack section 22 in the vertical direction. I have.

  On the operation side of the rack unit 22 by the operator, a rack door 24b that is freely openable in the vertical direction (arrow a in FIG. 3) is provided corresponding to the magazine entrance 24a of each magazine holding unit 24. In a state where the magazine door 24a is opened by opening the rack door 24b (upper side in FIG. 3), the magazine 40 is inserted and removed in the horizontal direction from the magazine door 24a corresponding to the rack door 24b. When the rack door 24b is closed, the magazine entrance 24a corresponding to the rack door 24b is closed (the lower side in FIG. 3). As described above, the rack portion 22 has the plurality of magazine holding portions 24 arranged in the vertical direction, and the magazine 40 inserted in the horizontal direction from the magazine entrance 24a provided corresponding to each magazine holding portion 24. Is held in the magazine holding unit 24.

  In FIG. 3, the pallet moving unit 23 is provided behind the rack unit 22 (on the side opposite to the side operated by the operator), and includes a pallet mounting table 25, an elevating mechanism 26, and an unloading mechanism 27. The elevating mechanism 26 has a ball screw 26a extending in the vertical direction and a motor 26b for driving the ball screw 26a to rotate. The lifting mechanism 26 drives the motor 26b to move the pallet mounting table 25 up and down (arrow b). The take-out mechanism 27 includes an engagement tool 27a and a moving mechanism 27b that moves the engagement tool 27a in the front-rear direction (Y direction) on the upper surface of the pallet table 25.

  The transfer of the pallet 7 between the magazine 40 and the pallet mounting table 25 is performed as follows. First, the elevating mechanism 26 is located behind a predetermined magazine 40 in which the pallet 7 to be taken out is stored (specifically, a pallet take-out port 24c provided corresponding to the magazine holding unit 24 holding the magazine 40). The pallet mounting table 25 is positioned at the transfer height (behind).

  Next, the moving mechanism 27b moves the engaging tool 27a to the pallet take-out port 24c (in the direction of the magazine 40) and engages with the engaging portion 7a (see FIG. 2) provided behind the pallet 7. The moving mechanism 27b pulls out the pallet 7 to the pallet mounting table 25 by moving the engaging member 27a backward in this state. The moving mechanism 27b stores the pallet 7 in the magazine 40 by moving the engaging tool 27a to the pallet outlet 24c (in the direction of the magazine 40) in a state where the engaging tool 27a is engaged with the engaging portion 7a. I do.

  When the pallet 7 is moved to the component supply position, the motor 26b is driven while the pallet 7 is pulled out of the magazine 40 and held on the pallet mounting table 25, and the pallet mounting table 25 is raised to the component supply position. As a result, the component P is supplied to the component supply position, and the component P can be mounted on the board 3 by the component mounting mechanism. As described above, the pallet moving unit 23 takes out the pallets 7 from the plurality of magazines 40 held in the rack unit 22 through the pallet outlets 24c provided corresponding to the respective magazine holding units 24 and moves them to the component supply position. . That is, the component supply device 5 takes out the pallet 7 on which the tray 6 for storing the component P is mounted from the magazine 40 for stacking and storing the pallet 7 and moves it to the component supply position.

  Next, a configuration of the magazine holding unit 24 of the component supply device 5 will be described with reference to FIGS. The structure of the two magazine holders 24 arranged in the up-down direction is the same. In the magazine holding section 24, a chain storage section 28 for storing a chain 30 (roller chain) and four sprockets 31 is provided between the magazine 40 to be held and the left and right side covers 22a of the rack section 22, respectively. I have. In FIG. 4, for convenience, only the positions of the pins 30c (see FIG. 8) inserted between the pair of outer plates 30a and the pair of inner plates 30b of the chain 30 are indicated by circles.

  In FIG. 4, the four sprockets 31 are arranged at the positions of the vertices of the rectangle in the YZ plane with the rotation axis 31a facing in the X direction. The chain 30 is attached so as to mesh with the four sprockets 31 and orbit in the YZ plane. That is, each magazine holding portion 24 has a pair of chains 30 facing each other in parallel in the magazine insertion direction (Y direction).

  In FIGS. 4 and 5, a rod 32 is suspended and provided between a part of the pins 30c of the pair of chains 30 (portion indicated by a black circle in FIG. 4). ). When there is no magazine 40 in the magazine holding section 24 (state of the upper magazine holding section 24), the pallet take-out port 24c is closed (blocked) by the plurality of rods 32. This prevents the worker from opening the rack door 24b and accessing the operating pallet moving unit 23 from the magazine doorway 24a opened and through the pallet outlet 24c. That is, the plurality of rods 32 function as shutters S (blocking means) provided to be suspended between the pair of chains 30, and block the pallet take-out port 24c with the magazine 40 removed.

  Here, with reference to FIGS. 6 to 8, the vicinity of the magazine entrance 24 a on the lower side of the chain 30 on the right side as viewed from the operation side by the operator (the C area indicated by a two-dot chain line rectangle in FIG. 4) will be described in detail. FIG. 6 illustrates a region C as viewed from the side cover 22a side. 6 omits the illustration of the side cover 22a, the inner wall 28a of the chain storage portion 28, the upper guide member 28b, and the lower guide member 28c, which will be described later, and FIG. 6 (b) further illustrates the chain 30 and the sprocket 31. The display is simplified. FIG. 7 illustrates a region C as viewed from the inside of the magazine holding unit 24. For convenience, FIG. 7B omits the illustration of the inner wall 28a, the upper guide member 28b, the lower guide member 28c of the chain storage unit 28, and the protection member 38 described later. FIG. 8 shows a DD cross section shown in FIG. 7A as viewed from the operation side by the operator.

  6 to 8 show a state in which the magazine 40 is not provided in the magazine holding portion 24. A connecting member 33 connected to the chain 30 and movable in the Y direction in conjunction with the running of the chain 30 connects the vicinity of the magazine entrance 24a. It has moved to position Pc. The connecting member 33 has a plate shape extending in the YZ plane, and an opening 33a that penetrates in the X direction and opens long in the Z direction is formed on the YZ surface of the connecting member 33. The other end of the connecting pin 34 connected to the chain 30 at one end and extending in the X direction penetrates through the opening 33a. The connecting pin 34 moves in the Y direction integrally with the chain 30, and at this time, the connecting pin 34 moves in the opening 33a in the Z direction.

  A U-shaped connection groove 33b is formed in an upper portion of the connection member 33 on the magazine entrance 24a side. One end of the connecting groove 33b is connected to a plate-like connecting member 42 disposed on the rear side (the side inserted into the magazine entrance 24a) of the lower portion of the side surface 41 of the magazine 40, and a connecting pin extending in the X direction. The other end of 43 (see FIGS. 13 and 14) is connected from above. The coupling member 42 is connected to the side surface 41 of the magazine 40 via a spacer 42a. That is, a gap corresponding to the thickness of the spacer 42a is formed between the side surface 41 of the magazine 40 and the coupling member 42.

  8, an upper guide member 28b and a lower guide member 28c extending in the Y direction are provided on the lower side of the inner wall 28a of the chain storage portion 28. The inner wall 28a, the upper guide member 28b, and the lower guide member 28c sandwich the connecting member 33 from above, below, left and right to form a guide path 28d that restricts the movement of the connecting member 33 in the X and Z directions and extends in the Y direction. (See also FIG. 12). The connecting member 33 is freely movable integrally with the chain 30 along the guide path 28d between the connecting position Pc near the magazine entrance 24a and the holding position Ph near the pallet take-out 24c.

  In FIGS. 6 and 7, below the chain 30 near the connection position Pc, a substantially rectangular plate-shaped end is connected to a rotation shaft 35a extending in the X direction and extends in a YZ plane swinging about the rotation shaft 35a. Is provided. The other end of the lock member 35 opposite to the rotation shaft 35a is urged upward by an elastic body such as a spring (not shown).

  In the chain 30, near the connected connecting pin 34 and closer to the pallet take-out port 24 c than the connecting pin 34, there is provided a lock pin 36 having one end extending in the X direction connected to the chain 30. I have. A recess 35b that engages with the lock pin 36 is formed on the upper side near the other end of the lock member 35 opposite to the rotation shaft 35a. The recess 35b of the lock member 35 urged upward is engaged with the lock pin 36 in a state where the connection member 33 is at the connection position Pc. As a result, the traveling of the pair of chains 30 is prevented (locked).

  Between the rotation shaft 35a of the lock member 35 and the concave portion 35b, a contact pin 37 having one end connected to the lock member 35 and extending in the X direction is provided. 8, the contact pin 37 extends to the vicinity of the protection member 38 through a notch 28e (see also FIG. 7A) formed in the lower guide member 28c. That is, the other end of the contact pin 37 extends to between the protection member 38 and the lower guide member 28c. The contact pin 37 swings inside the notch 28e integrally with the lock member 35.

  9 to 11, when the magazine 40 is inserted into the magazine holding portion 24, the engagement between the recess 35b and the lock pin 36 is released, and the traveling of the pair of chains 30 is permitted (unlocked). The operation up to this point will be described. 9 and 10, for convenience, the description of the magazine 40 is simplified and only the coupling member 42 and the coupling pin 43 are shown. FIG. 11 shows a DD section in FIG. 7A when the state of FIG. 9B is viewed from the side of the operation by the operator.

  In FIG. 11, the coupling member 42 enters between the protection member 38 and the upper guide member 28b and the lower guide member 28c, and moves together with the magazine 40 in the Y direction. The coupling member 42 comes into contact with the contact pin 37 extending from the top to the position between the protection member 38 and the lower guide member 28c at the connection position Pc. In FIG. 9, the lower surface of the coupling member 42 contacts the contact pin 37 and pushes down the contact surface 37 and a horizontal surface (hereinafter, referred to as a “pressed surface 42 b”) and a slope that is cut obliquely toward the magazine entrance 24 a ( Hereinafter, it is referred to as “pressed slope 42c”).

  In the step of inserting the magazine 40 into the magazine holding portion 24 and moving it to a position where the magazine 40 is held, first, the rear side of the magazine 40 (the side inserted into the magazine entrance 24a) is slightly lifted, and then moved to the connection position Pc. The connecting pin 33 is inserted into the connecting member 33 to be contacted (arrow e in FIG. 9A). Next, the rear side of the magazine 40 is lowered (arrow f), and the magazine 40 is placed so that the lower surface of the magazine 40 lands on the floor surface 24d of the magazine holding unit 24 (FIG. 9B).

  In the process from the state shown in FIG. 9A to the state shown in FIG. 9B, the connecting pin 43 (connecting portion) enters the connecting groove 33b and is connected to the connecting member 33. The pressing surface 42b contacts the contact pin 37 and presses it down, so that the lock member 35 swings downward (arrow g). Thereby, the concave portion 35b of the lock member 35 is disengaged from the lock pin 36, and the traveling of the pair of chains 30 is allowed (lock release) (see also FIG. 11).

  When the lock is released, the connecting member 42, the connecting pin 43, the connecting member 33, and the connecting pin 34 move integrally in the Y direction (arrow h in FIG. 10A). In the state shown in FIG. 10A, the pressed surface 42b is continuously in contact with the contact pin 37. The magazine 40 is further moved in the Y direction (arrow j in FIG. 10B), and when the connecting pin 34 passes above the lock member 35, the contact pin 37 moves upward along the pressing slope 42c (FIG. 10 (b)). With the upward movement of the contact pin 37, the lock member 35 swings upward (arrow k) and stops at the upper limit position by upper limit suppressing means (not shown).

  When pulling out the magazine 40 from the magazine holding part 24, the connecting pin 34 passes above the lock member 35 after the contact pin 37 is pushed down along the pressing slope 42c and the lock member 35 swings downward. Therefore, the lock member 35 does not interfere with the connecting pin 34 that reciprocates in the Y direction.

  As described above, the lock member 35 and the contact pin 37 allow the pair of chains 30 to travel while the magazine 40 is inserted into the magazine holding unit 24 and is placed on the floor surface 24d of the magazine holding unit 24 ( Unlocking) and a blocking means for blocking (locking) the running of the pair of chains 30 when the magazine 40 is not placed. The blocking means allows the pair of chains 30 to travel (unlocks) with the connecting pin 43 (connecting part) connected to the connecting member 33 (connecting means). The pressing surface 42b of the coupling member 42 is in a state in which the blocking means allows the pair of chains 30 to travel (unlocks) when the coupling pin 43 (the coupling portion) is coupled to the coupling member 33 (the coupling means). Opening means.

  Further, the pair of chains 30 further has a lock pin 36 connected to the pair of chains 30. The lock member 35 (blocking means) further has a concave portion 35b (engagement mechanism) that engages with the lock pin 36 to prevent the pair of chains 30 from running. The pressing surface 42b of the coupling member 42 comes into contact with the contact pin 37 to push down the lock member 35, remove the lock pin 36 from the concave portion 35b (engagement mechanism) engaged with the lock pin 36, and Opening means for allowing the chain 30 to travel.

  In FIG. 11, the gap secured by the spacer 42a between the area where the coupling member 42 moves while the magazine 40 is inserted into the magazine holding portion 24 and moved to the holding position Ph and the side face 41 of the magazine 40 is In addition, a plate-like protection member 38 that stands on the floor surface 24d of the magazine holding portion 24 and extends in the Y direction is provided. That is, the magazine holding section 24 has the protection member 38 between the lock member 35 (blocking means) and the magazine 40 inserted into the magazine holding section 24.

  The protection member 38, together with the upper guide member 28b and the lower guide member 28c, protects the contact pin 37 from being touched by an operator's finger. Thereby, safety is ensured so that the lock of the chain 30 cannot be released by a method other than the operator inserting the magazine 40. In FIG. 7, the operator's operation side of the chain storage unit 28 is closed by the front cover 22b. Further, the front cover 22b extends in the X direction to a position where the front cover 22b does not interfere with the inserted coupling member 42, and protects the contact pin 37 from swinging from the operation side (see also FIG. 5).

  Next, an operation of the chain 30 until the magazine 40 is inserted into and held in the magazine holding unit 24 will be described with reference to FIG. In FIG. 12, for convenience, the description of the magazine 40 is simplified, and only the connecting member 42 is shown, and the position of the connecting pin 34 is indicated by a black circle. In FIG. 12, the description of the blocking means for blocking (locking) the traveling of the chain 30 and the description of the process of unlocking are omitted.

  In FIG. 12A, the magazine 40 is inserted into the magazine holding portion 24, and the coupling pin 43 of the coupling member 42 is coupled from above to the coupling groove 33b of the coupling member 33 located at the coupling position Pc (arrow m). That is, the coupling pin 43 is a coupling portion that is coupled to the coupling member 33 (the coupling means) when the magazine 40 is inserted into each magazine holding portion 24.

  In FIG. 12B, when the magazine 40 is moved toward the pallet take-out port 24c, the connecting member 42, the connecting pin 43, the connecting member 33, and the connecting pin 34 move integrally in the Y direction (arrow n). . Thus, the chain 30 connected to the connecting pin 34 runs counterclockwise in FIG. 12B (arrow o), and the plurality of rods 32 (shutters S) that have blocked the pallet outlet 24c are sequentially moved upward. Go to

  In FIG. 8C, when the magazine 40 is moved to the holding position Ph held by the magazine holding unit 24, all the rods 32 (shutters S) move upward and the pallet take-out port 24c is opened. As a result, the pallet 7 stored in the magazine 40 can be pulled out to the pallet mounting table 25 through the pallet outlet 24c.

  Thus, the pair of chains 30 travels in conjunction with the insertion and removal of the magazine 40 into and out of the magazine holding unit 24. The pair of chains 30 has a connecting member 33 (connecting means) that works in conjunction with the traveling of the pair of chains 30. Each magazine holding unit 24 is provided with a blocking means (shutter S) that closes and opens in conjunction with the loading and unloading of the magazine 40 from the magazine entrance 24a, and blocks the pallet removal port 24c when the magazine 40 is removed. I have.

  The connecting means for connecting the magazine 40 to the chain 30 is not limited to the method using the connecting member 33, and for example, the connecting pin 34 connected to the chain 30 is directly connected to the connecting member 42 connected to the magazine 40. You may make it engage and connect.

  Further, the magazine 40 is inserted to a predetermined position (connection position Pc) of the magazine holding portion 24 by the above-described blocking means for preventing (locking) the running of the chain 30, and the connection pin 43 is connected to the connection member 33. Until the unlocking of the pair of chains 30 is performed, the traveling of the pair of chains 30 is blocked. This also prevents the movement of the plurality of rods 32 (shutters S) that block the pallet take-out port 24c. That is, it is ensured that the shutter S (blocking means) blocks the pallet take-out port 24c in a state where the magazine 40 is not inserted into the magazine holding unit 24, and the safety of the worker is secured.

  Next, the configuration of the magazine 40 will be described with reference to FIGS. In FIGS. 13 to 15, the side where the magazine 40 is inserted into the magazine entrance 24 a when the magazine 40 is inserted into the magazine holding portion 24 is referred to as a rear side, and the opposite side is referred to as a front side. The right hand and the left hand are respectively referred to as the right side and the left hand as viewed from the front side, and the upper and lower sides are defined as upper and lower sides, respectively. In FIG. 13, a grip portion 44 that is gripped by an operator when the magazine 40 is inserted into the magazine holding portion 24 is provided in an upper portion on the front side of the left and right side surfaces 41.

  In FIG. 14B, a plurality of (here, six levels) shelves 45 are provided in the magazine 40 in the vertical direction, and each shelf 45 stores a pallet 7 on which the tray 6 is mounted. I have. On the upper part of the magazine 40, there is provided a bar 41a for preventing the pallet 7 from jumping out from above.

  In front of the magazine 40, a magazine door 46 that can be freely opened in the vertical direction (arrow p in FIG. 13B) is provided. That is, the magazine 40 has the magazine door 46 that opens and closes on the side facing the magazine entrance 24a while being held by each magazine holding unit 24. The operator puts the pallet 7 in and out of the shelf 45 with the magazine door 46 opened (FIGS. 13B and 14B).
