[0032] In Japanese Patent Publication No. 2017-163006, the pair of fall-off prevention parts provided in the storage bin are structures that move separately (between a restricted position and a non-restricted position). Therefore, in order for the tray feeder to be able to extract the pallet from the storage bin, two mechanisms are required to simultaneously operate the pair of fall-off prevention parts. Therefore, there is a problem that the mechanism of the tray feeder becomes complicated and the cost becomes high.

[0033] Therefore, an object of the present invention is to provide a component assembly device, a tray feeder, and a storage bin that can achieve cost reduction while reliably preventing a pallet from falling off from a storage bin.

[0034] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 1 is a side view showing a component assembly device 1 according to an embodiment of the present invention. The component assembly device 1 is a device that picks up the component BH stored in the tray TR and assembles it on the substrate KB, and includes a base 11, a conveyor 12, a tray feeder 13, an assembly head 14, and a head moving mechanism 15. In the present embodiment, for the sake of convenience of explanation, the left-right direction observed by the operator OP is set as the X-axis direction, and the front-back direction observed by the operator OP is set as the Y-axis direction. In addition, the up-down direction is set as the Z-axis direction. Furthermore, in the front-back direction (Y-axis direction), the inner side observed by the operator OP is set as the front, and the near-front side observed by the operator OP is set as the rear.

[0035] The conveyor 12 is provided on the upper surface of the base 11, and conveys the substrate KB along the X-axis direction and positions it at a predetermined working position. The tray feeder 13 is a component supply device, and extracts the pallet PL holding the tray TR storing the component BH and positions the pallet PL at a predetermined component supply height. The assembly head 14 has a suction nozzle 14N at the lower end for sucking the component BH. The head moving mechanism 15 moves the assembly head 14 between a position above the pallet PL at the component supply height and a position above the substrate KB positioned by the conveyor 12.

[0036] Figure 2 It is a perspective view of the tray feeder 13 provided in the component mounting device 1 . Figure 3 is a perspective side view of the tray feeder 13. Figure 2 and Figure 3 In the tray feeder 13, there is a trolley 21, a frame 22, a storage bin 23, a drawer table 24, and a table lift 25. The trolley 21 is movable on the floor surface by a plurality of wheels 21a, and is arranged at the rear of the base 11. The frame 22 is mounted on the rear of the trolley 21, and has a plurality of storage bin setting shelves 22T arranged vertically inside. The storage bin setting shelf 22T is provided with a storage bin 23. The storage bin setting shelf 22T functions as a storage bin setting part in the tray feeder 13. In the storage bin 23, a plurality of pallets PL are stored in a state of being arranged in the vertical direction.

[0037] Figure 4 It is a perspective view of a part of the tray feeder 13 . Figure 5A as well as Figure 5B 13 is an operation diagram for explaining the tray feeder 13. Figure 4 In the embodiment, the pallet PL has a disk shape, and a pallet TR is placed on the upper surface. A plurality of recesses PK are arranged in an array on the pallet TR, and a component BH is accommodated in each recess PK. The pallet TR is fixed to the upper surface of the pallet PL by a fixing member KG such as a magnet. A pair of engaged blocks BL are arranged opposite to each other in the left-right direction (X-axis direction) at the front edge of the pallet PL.

[0038] exist Figure 2 , Figure 3 and Figure 4 In the embodiment, the drawer 24 is located in the front area of ​​the frame 22. Figure 4 As shown in FIG. 1 , a tray extraction portion 24R and a pair of tray guides 24G are provided on the extraction platform 24. The tray extraction portion 24R is composed of a rod-shaped member extending in the X-axis direction and is provided to be movable in the Y-axis direction on the extraction platform 24 (in Figure 4A pair of pallet guides 24G extend in the Y-axis direction and are disposed opposite to each other in the X-axis direction at positions of the pallet drawer 24R sandwiching the upper surface of the drawer table 24 in the X-axis direction.

[0039] exist Figure 2 and Figure 3 In the drawing, the table lifting section 25 includes: front and rear guide posts 25T, which are arranged to extend upward from the carriage 21; a ball screw 25B, which extends in the Z-axis direction; and a lifting motor 25M, which drives the ball screw 25B to rotate around the Z-axis. The ball screw 25B is screwed with a nut portion 24N provided at the front of the drawer table 24, and the guide post 25T guides the movement of the drawer table 24 in the Z-axis direction. The lifting motor 25M causes the ball screw 25B to rotate around the Z-axis, thereby raising and lowering the drawer table 24 via the nut portion 24N (in the drawing). Figure 3 The table 24 is configured to be able to be raised and lowered freely under the action of the table lifting part 25.

[0040] When the pallet PL stored in the storage bin 23 is pulled out by the pallet pull-out portion 24R, the lifting motor 25M is operated to lift the pull-out table 24 so that the upper surface of the pull-out table 24 is located at a position (height) for storing the pallet PL to be pulled out. After the upper surface of the pull-out table 24 is located at the height of the pallet PL to be pulled out, the pallet pull-out portion 24R is moved backward (toward the side where the frame 22 is provided) so that the left and right ends of the pallet pull-out portion 24R are engaged with a pair of engaged blocks BL ( Figure 4 → Figure 5A Then, after both ends of the pallet extraction part 24R are engaged with a pair of engaged blocks BL, the pallet extraction part 24R is moved forward. As a result, the pallet PL is extracted forward and placed on the upper surface of the extraction platform 24 ( Figure 5A → Figure 5B At this time, the pallet PL moves on the drawer table 24 with both side surfaces guided by the left and right pallet guides 24G, and is therefore placed on the drawer table 24 in a straight posture without being tilted relative to the drawer table 24.

[0041] Next, the structure of the storage compartment 23 will be described. Figure 6 as well as Figure 7 This is a perspective view of the storage compartment 23 included in the tray feeder 13 as viewed from the upper front. Figure 8 as well as Fig. 9 This is a three-dimensional view of the storage bin 23 observed from the rear and upper side. Figure 6 , Figure 7 , Figure 8 and Fig. 9In the embodiment, the storage bin 23 includes left and right side plates 31, a top plate 32, and a bottom plate 33. The left and right side plates 31 are opposite to each other in the X-axis direction, and the upper and lower ends are connected to each other by the top plate 32 and the bottom plate 33, respectively. The storage bin 23 as a whole has a shape that is opened at the front and the back, and includes a front entrance 23F as a front pallet entrance and exit, and a rear entrance 23A as a rear pallet entrance and exit. The storage bin 23 includes a plurality of slots 23S arranged in the up-down direction inside, and each slot 23S stores a pallet PL in a horizontal posture.

[0042] exist Figure 6 and Figure 7 In the embodiment, a front pallet fall-off prevention mechanism 40A is provided at the front portion of the front area of ​​the storage bin 23, and the front pallet fall-off prevention mechanism 40A prevents the pallet PL stored in the storage bin 23 from moving to the outside (front) from the front entrance 23F and falling off (falling out). The front pallet fall-off prevention mechanism 40A is composed of the following components: a pair of fall-off prevention parts (a first fall-off prevention part 41 and a second fall-off prevention part 42) which are provided at the left and right ends of the front entrance 23F of the storage bin 23; and a motion transmission mechanism (a front motion transmission mechanism 50A) which transmits motion between the pair of fall-off prevention parts.

[0043] exist Figure 8 and Fig. 9 In the embodiment, a rear pallet fall-off prevention mechanism 40B is provided in the rear area of ​​the storage bin 23, and the rear pallet fall-off prevention mechanism 40B prevents the pallet PL stored in the storage bin 23 from moving to the outside (rearward) from the rear entrance 23A and falling off. The rear pallet fall-off prevention mechanism 40B is composed of the following components: a pair of fall-off prevention parts (third fall-off prevention parts 43 and fourth fall-off prevention parts 44) which are provided at the left and right ends of the rear entrance 23A of the storage bin 23; and a motion transmission mechanism (rear motion transmission mechanism 50B) which transmits motion between the pair of fall-off prevention parts.

[0044] exist Figure 6 and Figure 7In the embodiment, the first fall-off prevention part 41 and the second fall-off prevention part 42 constituting the front pallet fall-off prevention mechanism 40A are arranged at the left and right ends of the front entrance 23F of the storage bin 23. The first fall-off prevention part 41 is composed of the following components: upper and lower first swinging pieces 41M, which are movable members arranged at one side of the left and right ends in front of the storage bin 23; and a first rod 41R, which is a rod member whose upper and lower ends are supported by the above-mentioned upper and lower first swinging pieces 41M. The second fall-off prevention part 42 is composed of the following components: upper and lower second swinging pieces 42M, which are movable members arranged at the other side of the left and right ends in front of the storage bin 23; and a second rod 42R, which is a rod member whose upper and lower ends are supported by the above-mentioned upper and lower second swinging pieces 42M.

[0045] exist Figure 6 and Figure 7 In the embodiment, the upper and lower first swing pieces 41M are pivotally supported by upper and lower first pivot pins 41P arranged in a manner having a common upper and lower axis on the top plate 32 and the bottom plate 33 of the storage bin 23 (the lower first pivot pin is omitted in the figure). Therefore, the first fall-off prevention portion 41 composed of the upper and lower first swing pieces 41M and the first rod 41R is integrated and swings around the upper and lower axes of the upper and lower first pivot pins 41P.

[0046] The upper and lower first swing pieces 41M are respectively provided with first swing piece extensions 41H extending outwardly of the storage compartment 23. The upper and lower ends of a front operating rod 41D extending in the vertical direction are attached to the upper and lower first swing piece extensions 41H.

[0047] exist Figure 6 and Figure 7 In the embodiment, the upper and lower second swing pieces 42M are pivotally supported by upper and lower second pivot pins 42P arranged in a manner having a common upper and lower axis on the top plate 32 and the bottom plate 33 of the storage bin 23 (the lower second pivot pin is omitted in the figure). Therefore, the second fall-off prevention portion 42 composed of the upper and lower second swing pieces 42M and the second rod 42R is integrated and swings around the upper and lower axes of the upper and lower second pivot pins 42P.

[0048] The first fall-off prevention portion 41 and the second fall-off prevention portion 42 are freely movable between a restricted position that restricts the movement of the pallet PL from the front entrance 23F to the outside (front) of the storage bin 23 and a non-restricted position that does not restrict the movement of the pallet PL from the front entrance 23F to the outside of the storage bin 23. In addition, the first rod 41R of the first fall-off prevention portion 41 and the second rod 42R of the second fall-off prevention portion 42 are located on the movement path of the pallet PL from the front entrance 23F to the outside (front) of the storage bin 23 when the first fall-off prevention portion 41 and the second fall-off prevention portion 42 are located in the restricted position. Figure 6 ), and when the first fall-off prevention portion 41 and the second fall-off prevention portion 42 are in the non-restricted position, the position is located in the moving path of the detached pallet PL from the front entrance 23F to the outside of the storage bin 23 (specifically, the left and right sides of the storage bin 23) ( Figure 7 ).

[0049] In a state where the first fall-off preventing portion 41 and the second fall-off preventing portion 42 are located at the restricting position and the first rod 41R and the second rod 42R are located on the moving path of the pallet PL ( Figure 6 ), the left and right ends of the pallet PL abut against the first rod 41R and the second rod 42R. Therefore, the pallet PL cannot move to the outside of the storage bin 23, and the pallet PL is prevented from falling off from the storage bin 23. On the other hand, when the first fall-off prevention portion 41 and the second fall-off prevention portion 42 are located in the non-restricted position and the first rod 41R and the second rod 42R are located in a position away from the moving path of the pallet PL ( Figure 7 ), the pallet PL does not contact the first rod 41R and the second rod 42R. Therefore, the pallet PL can be pulled out of the storage bin 23.

[0050] exist Figure 8 and Fig. 9 In the embodiment, the third fall-off prevention part 43 and the fourth fall-off prevention part 44 constituting the rear pallet fall-off prevention mechanism 40B are arranged at the left and right ends of the rear entrance 23A of the storage bin 23. The third fall-off prevention part 43 is composed of the following components: upper and lower third swing pieces 43M, which are movable components arranged at one side of the left and right ends at the rear of the storage bin 23; and a third rod 43R, which is a rod component supported by the upper and lower third swing pieces 43M. The fourth fall-off prevention part 44 is composed of the following components: upper and lower fourth swing pieces 44M, which are movable components arranged at the other side of the left and right ends at the rear of the storage bin 23; and a fourth rod 44R, which is a rod component supported by the upper and lower fourth swing pieces 44M.

[0051] exist Figure 8 and Fig. 9In the embodiment, the upper and lower third swing pieces 43M are pivotally supported by the upper and lower third pivot pins 43P arranged in a manner having a common upper and lower axis on the top plate 32 and the bottom plate 33 of the storage bin 23 (the lower third pivot pin is omitted in the figure). Therefore, the third fall-off prevention portion 43 composed of the upper and lower third swing pieces 43M and the third rod 43R is integrated and swings around the upper and lower axis of the upper and lower third pivot pins 43P.

[0052] The third swing piece extensions 43H extending outward from the storage compartment 23 are provided on the upper and lower third swing pieces 43M, respectively. The upper and lower ends of a rear operating rod 43D extending in the vertical direction are mounted on the upper and lower third swing piece extensions 43H.

[0053] exist Figure 8 and Fig. 9 In the embodiment, the upper and lower fourth swing pieces 44M are pivotally supported by the upper and lower fourth pivot pins 44P arranged in a manner having a common upper and lower axis on the top plate 32 and the bottom plate 33 of the storage bin 23 (the lower fourth pivot pin is omitted in the figure). Therefore, the fourth fall-off prevention portion 44 composed of the upper and lower fourth swing pieces 44M and the fourth rod 44R is integrated and swings around the upper and lower axis of the upper and lower fourth pivot pins 44P.

[0054] The third fall-off prevention portion 43 and the fourth fall-off prevention portion 44 are freely movable between a restricted position that restricts the movement of the pallet PL from the rear entrance 23A to the outside (rear) of the storage bin 23 and a non-restricted position that does not restrict the movement of the pallet PL from the rear entrance 23A to the outside of the storage bin 23. In addition, when the third fall-off prevention portion 43 and the fourth fall-off prevention portion 44 are located in the restricted position, the third rod 43R of the third fall-off prevention portion 43 and the fourth rod 44R of the fourth fall-off prevention portion 44 are located on the movement path of the pallet PL from the rear entrance 23A to the outside (rear) of the storage bin 23 ( Figure 8 ), and when the third fall-off prevention portion 43 and the fourth fall-off prevention portion 44 are in the non-restricted position, they are located at a position of the moving path of the detached pallet PL from the rear entrance 23A to the outside of the storage bin 23 (specifically, the left and right sides of the storage bin 23) ( Fig. 9 ).

[0055] In a state where the third fall-off preventing portion 43 and the fourth fall-off preventing portion 44 are located at the restricting position and the third rod 43R and the fourth rod 44R are located on the moving path of the pallet PL ( Figure 8), the left and right ends of the pallet PL abut against the third rod 43R and the fourth rod 44R. Therefore, the pallet PL cannot move to the outside from the rear entrance 23A of the storage bin 23, and the pallet PL is prevented from falling off from the storage bin 23. On the other hand, when the third fall-off prevention portion 43 and the fourth fall-off prevention portion 44 are in the non-restricted position and the third rod 43R and the fourth rod 44R are in a position away from the moving path of the pallet PL ( Fig. 9 ), the pallet PL does not contact the third rod 43R and the fourth rod 44R. Therefore, the pallet PL can be drawn out from the rear entrance 23A of the storage bin 23 to the outside.

[0056] exist Figure 6 and Figure 7 In the embodiment, the front motion transmission mechanism 50A constituting the front pallet fall-off prevention mechanism 40A is arranged in the front area above the top plate 32. The front motion transmission mechanism 50A transmits the motion of one of the first fall-off prevention part 41 and the second fall-off prevention part 42 (the first fall-off prevention part 41) moving from the restricted position to the non-restricted position to the other (the second fall-off prevention part 42), thereby causing the other fall-off prevention part (the second fall-off prevention part 42) to move from the restricted position to the non-restricted position. In addition, the front motion transmission mechanism 50A transmits the motion of the first fall-off prevention part 41 moving from the non-restricted position to the restricted position to the second fall-off prevention part 42, thereby causing the second fall-off prevention part 42 to move from the non-restricted position to the restricted position. In the present embodiment, the front motion transmission mechanism 50A realizes the above-mentioned action by forming a link mechanism that causes the first anti-falling part 41 and the second anti-falling part 42 to always move (swing) in opposite directions, and causes the left and right rod members (the first rod 41R and the second rod 42R) to move in a manner of separating from or approaching each other.

[0057] exist Figure 6 and Figure 7 In the embodiment, the front motion transmission mechanism 50A includes a front intermediate member 51, a front operating side rod 52, and a front operated side rod 53. The front intermediate member 51 extends in the front-to-back direction in the middle portion of the front region of the upper surface of the top plate 32, and its middle portion is pivotally supported on the top plate 32 by a front pivot pin 51P. The front operating side rod 52 has a shape extending in the left-right direction, and both ends are pivotally connected to one end side of the front intermediate member 51 in the front-to-back direction and the rear end side of the first swinging piece 41M (the portion that is more rearward than the first pivot pin 41P). The front operated side rod 53 also has a shape extending in the left-to-right direction, and both ends are pivotally connected to the other end side of the front intermediate member 51 in the front-to-back direction and the rear end side of the second swinging piece 42M (the portion that is more rearward than the second pivot pin 42P).

[0058] exist Figure 6 and Figure 7In the embodiment, at least one of the upper and lower first swing pieces 41M (here, only the upper first swing piece 41M) is urged toward the restricted position by the urging mechanism (front urging spring 41S) provided between the at least one first swing piece 41M and the spring support portion 41K of the side plate 31 mounted on the storage bin 23. In addition, thereby, the lower first swing piece 41M and the upper and lower second swing pieces 42M located below the upper first swing piece 41M are also urged toward the restricted position through the front motion transmission mechanism 50A, the first rod 41R, and the second rod 42R.

[0059] Fig. 10A as well as Fig. 10B FIG. 2 is a top view of a portion of the storage bin 23 for explaining the operation of the front pallet fall-off prevention mechanism 40A provided in the storage bin 23. Fig. 10A As shown, in a state where no external force is applied to either the first fall-off prevention portion 41 or the second fall-off prevention portion 42, under the action of the force of the front force spring 41S, the first fall-off prevention portion 41 and the second fall-off prevention portion 42 are both located in the restricted position, and the first rod 41R and the second rod 42R are located in front of the front entrance 23F of the storage bin 23 (on the moving path of the pallet PL), thereby preventing the pallet PL from falling off the storage bin 23.

[0060] When from Fig. 10A When the force P1 acts on the first swing piece extension 41H in the rearward direction, the first swing piece 41M overcomes the force of the front biasing spring 41S and swings in the counterclockwise direction R1 with the first pivot pin 41P as the fulcrum, and is located in the non-restricted position ( Fig. 10B ). The front operating side lever 52 utilizes the movement of the first swinging piece 41M to move the front operating side lever 52 as a whole toward the second swinging piece 42M, and the front intermediate member 51 swings in the clockwise direction R2 with the front pivot pin 51P as the fulcrum. In addition, the front operated side lever 53 is thereby moved as a whole toward the first swinging piece 41M, so that the second swinging piece 42M swings in the clockwise direction R3 with the second pivot pin 42P as the fulcrum and is located in the non-restricted position.

[0061] In the above series of actions, the first swing piece 41M and the second swing piece 42M swing in opposite directions, and the first rod 41R and the second rod 42R move in a manner of separating from each other and are respectively located in the non-restricted position. Fig. 10B ), since the first rod 41R and the second rod 42R are both located on the left and right sides of the front entrance 23F of the storage bin 23, the pallet PL can move forward from the front entrance 23F of the storage bin 23.

[0062] When from Fig. 10B When the force P1 acting on the first swing piece extension 41H is removed, the first swing piece 41M swings clockwise under the force of the front biasing spring 41S and returns to the restricted position ( Fig. 10A ). As a result, the front operating side lever 52 moves toward the first swing piece 41M, the front intermediate member 51 swings counterclockwise, and the front operated side lever 53 moves toward the second swing piece 42M. As a result, the second swing piece 42M swings counterclockwise with the second pivot pin 42P as a fulcrum, and returns to the restricted position.

[0063] In the above series of actions, the first swing piece 41M and the second swing piece 42M swing in opposite directions, and the first rod 41R and the second rod 42R move toward each other and are located at the restricted positions. Fig. 10A ), the movement of the pallet PL from the front entrance 23F of the storage bin 23 is restricted again.

[0064] exist Figure 8 and Fig. 9 In the embodiment, the rear action transmission mechanism 50B constituting the rear support plate fall-off prevention mechanism 40B is arranged in the rear area above the top plate 32. The rear action transmission mechanism 50B transmits the action of one of the third fall-off prevention part 43 and the fourth fall-off prevention part 44 (the third fall-off prevention part 43) moving from the restricted position to the non-restricted position to the other (the fourth fall-off prevention part 44), thereby causing the other fall-off prevention part (the fourth fall-off prevention part 44) to move from the restricted position to the non-restricted position. In addition, the rear action transmission mechanism 50B transmits the action of the third fall-off prevention part 43 moving from the non-restricted position to the restricted position to the fourth fall-off prevention part 44, thereby causing the fourth fall-off prevention part 44 to move from the non-restricted position to the restricted position. In this embodiment, the rear action transmission mechanism 50B realizes the above-mentioned action by forming a connecting rod mechanism that causes the third anti-falling part 43 and the fourth anti-falling part 44 to always move (swing) in opposite directions, and causes the left and right rod components (the third rod 43R and the fourth rod 44R) to move in a manner of separating from or approaching each other.

[0065] exist Figure 8 and Fig. 9In the embodiment, the rear motion transmission mechanism 50B includes a rear intermediate member 55, a rear operating side rod 56 and a rear operated side rod 57. The rear intermediate member 55 extends in the front-to-back direction at the middle portion of the rear region of the upper surface of the top plate 32, and its middle portion is pivotally supported on the top plate 32 by a rear pivot pin 55P. The rear operating side rod 56 has a shape extending in the left-right direction, and both ends are pivotally connected to one end side of the rear intermediate member 55 in the front-to-back direction and the front end side of the third swing piece 43M (a portion forward of the third pivot pin 43P). The rear operated side rod 57 also has a shape extending in the left-to-right direction, and both ends are pivotally connected to the other end side of the rear intermediate member 55 in the front-to-back direction and the front end side of the fourth swing piece 44M (a portion forward of the fourth pivot pin 44P).

[0066] exist Figure 8 and Fig. 9 In the embodiment, at least one of the upper and lower third swing pieces 43M (here, only the upper third swing piece 43M) is urged toward the restricted position by the urging mechanism (rear urging spring 43S) provided between the at least one third swing piece 43M and the spring support portion 43K installed on the side plate 31 of the storage bin 23. In addition, the lower third swing piece 43M and the upper and lower fourth swing pieces 44M located below the upper third swing piece 43M are also urged toward the restricted position through the rear motion transmission mechanism 50B, the third rod 43R and the fourth rod 44R.

[0067] Fig.11A as well as Fig. 11B 2 is a top view of a portion of the storage bin 23 for explaining the operation of the rear pallet fall-off prevention mechanism 40B provided in the storage bin 23. Fig.11A As shown, in a state where no external force is applied to either the third fall-off prevention portion 43 or the fourth fall-off prevention portion 44, under the action of the force of the rear force spring 43S, the third fall-off prevention portion 43 and the fourth fall-off prevention portion 44 are both located in the restricted position, and the third rod 43R and the fourth rod 44R are located behind the rear entrance 23A of the storage bin 23 (on the moving path of the pallet PL), thereby preventing the pallet PL from falling off the storage bin 23.

[0068] When from Fig.11A When the force P2 is applied to the third swing piece extension 43H in the forward direction in the state shown, the third swing piece 43M overcomes the force of the rear biasing spring 43S and swings in the counterclockwise direction R4 with the third pivot pin 43P as the fulcrum, and is located in the non-restricted position ( Fig. 11B). The rear operating side lever 56 utilizes the movement of the third swinging piece 43M to move the entirety toward the fourth swinging piece 44M, and the rear intermediate member 55 swings in the clockwise direction R5 with the rear pivot pin 55P as the fulcrum. In addition, the rear operated side lever 57 is thereby moved entirely toward the third swinging piece 43M, so that the fourth swinging piece 44M swings in the clockwise direction R6 with the fourth pivot pin 42P as the fulcrum and is located at the non-restricted position.

[0069] In the above series of actions, the third swing piece 43M and the fourth swing piece 44M swing in opposite directions, and the third rod 43R and the fourth rod 44R move in a manner of separating from each other and are respectively located in the non-restricted position. Fig. 11B ), since the third rod 43R and the fourth rod 44R are both located on the left and right sides of the rear entrance and exit 23A of the storage bin 23, the pallet PL can move backward from the rear entrance and exit 23A of the storage bin 23.

[0070] When from Fig. 11B When the force P2 acting on the third swing piece extension 43H is removed, the third swing piece 43M swings clockwise under the force of the rear biasing spring 43S and returns to the restricted position ( Fig.11A ). As a result, the rear operating side rod 56 moves toward the third swing piece 43M, the rear intermediate member 55 swings counterclockwise, and the rear operated side rod 57 moves toward the fourth swing piece 44M. As a result, the fourth swing piece 44M swings counterclockwise with the fourth pivot pin 44P as a fulcrum and returns to the restricted position.

[0071] In the above series of actions, the third swing piece 43M and the fourth swing piece 44M swing in opposite directions, and the third rod 43R and the fourth rod 44R move toward each other and are located at the restricted positions. Fig.11A ), the movement of the pallet PL from the rear entrance 23A of the storage bin 23 is restricted again.

[0072] Thus, in the storage bin 23 of the present embodiment, the front pallet fall-off prevention mechanism 40A comprises: a first fall-off prevention portion 41 and a second fall-off prevention portion 42, which are a pair of fall-off prevention portions that are movable between a restricted position for restricting the movement of the pallet PL from the front entrance 23F to the outside (front) of the storage bin 23 and a non-restricted position for not restricting the movement of the pallet PL from the front entrance 23F to the outside of the storage bin 23; and a front motion transmission mechanism 50A, which is a motion transmission mechanism for transmitting the motion of moving one of the pair of fall-off prevention portions, i.e., the first fall-off prevention portion 41, from the restricted position to the non-restricted position to the other of the pair of fall-off prevention portions, i.e., the second fall-off prevention portion 42, thereby moving the second fall-off prevention portion 42 from the restricted position to the non-restricted position. In detail, a pair of fall-off prevention parts (first fall-off prevention part 41 and second fall-off prevention part 42) include a pair of rod members (first rod 41R and second rod 42R) extending in the up-down direction and configured to move in a manner of separating from or approaching each other, and when located in the restricted position, the pair of rod members are located on the moving path of the pallet PL from the front entrance 23F to the outside of the storage bin 23, and when located in the non-restricted position, the pair of rod members are located at a position away from the moving path of the pallet PL.

[0073] In addition, the rear pallet fall-off prevention mechanism 40B includes: a third fall-off prevention portion 43 and a fourth fall-off prevention portion 44, which are a pair of fall-off prevention portions that are movable between a restricted position that restricts movement from the rear entrance 23A to the outside (rear) of the storage bin 23 and a non-restricted position that does not restrict movement from the rear entrance 23A to the outside of the storage bin 23; and a rear motion transmission mechanism 50B, which is a motion transmission mechanism that transmits the motion of moving one of the pair of fall-off prevention portions, i.e., the third fall-off prevention portion 43, from the restricted position to the non-restricted position to the other of the pair of fall-off prevention portions, i.e., the fourth fall-off prevention portion 44, thereby moving the fourth fall-off prevention portion 44 from the restricted position to the non-restricted position. In detail, a pair of fall-off prevention parts (third fall-off prevention part 43 and fourth fall-off prevention part 44) include a pair of rod members (third rod 43R and fourth rod 44R) extending in the up-down direction and configured to move in a manner of separating from or approaching each other, and when the pair of rod members are in the restricted position, the pair of rod members are located on the moving path of the pallet PL from the rear entrance 23A to the outside of the storage bin 23, and when the pair of rod members are in the non-restricted position, the pair of rod members are located at a position away from the moving path of the pallet PL.

[0074] Fig. 12A as well as Fig. 12B2 is a cross-sectional top view of the tray feeder 13 showing the step of setting the storage bin 23 in the frame 22 of the tray feeder 13. When the storage bin 23 of the above structure is set in the frame 22 (the storage bin is provided with a shelf 22T), the storage bin 23 is opened from the opening 22K ( Figure 2 ) is inserted into the rack 22 ( Fig. 12A → Fig. 12B ).like Fig. 12A , Fig. 12B As shown, a pair of storage bin installation guides 22G extending along the X-axis are provided on the upper surface of the storage bin installation shelf 22T. The storage bin 23 is guided by these storage bin installation guides 22G to move along the X-axis direction on the storage bin installation shelf 22T and is fixed to a predetermined position on the storage bin installation shelf 22T. When the storage bin 23 is installed on the storage bin installation shelf 22T in this way, the plurality of pallets PL in the storage bin 23 are installed together in the frame 22.

[0075] exist Fig. 12A , Fig. 12B In the embodiment, an operating cylinder 61 is installed on the frame 22. The operating cylinder 61 is installed on the inner surface of the side wall 22W of the frame 22, which is located on the side opposite to the side where the opening 22K is provided, in such a manner that the piston rod 62 extends in the Y-axis direction and the front end side faces forward. Fig. 12A , Fig. 12B As shown, a locking hook 63 that is open toward the opening 22K (here, L-shaped in cross section) is attached to the piston rod 62. The operation cylinder 61 can move the locking hook 63 in the Y-axis direction by moving the piston rod 62 forward and backward in the Y-axis direction.

[0076] Fig.13A as well as Fig. 13B 1 is a partial top view of the tray feeder 13 for explaining the operation of the operating cylinder 61 provided in the tray feeder 13. The operating cylinder 61 is provided corresponding to each of the plurality of storage bin installation shelves 22T provided in the frame 22. When the storage bin 23 is provided on the storage bin installation shelf 22T, the front operating rod 41D of the storage bin 23 is locked to the locking hook 63 ( Fig. 12A → Fig. 12B ). Therefore, after the storage bin 23 is set on the storage bin setting shelf 22T ( Fig. 12B ), the operating cylinder 61 is operated to move the locking hook 63 backward ( Fig.13A → Fig. 13B), thereby overcoming the force of the front biasing spring 41S and moving the front operating rod 41D backward. When the front operating rod 41D moves backward, the first fall-off prevention portion 41 moves from the restricted position to the non-restricted position, and then the second fall-off prevention portion 42 moves from the restricted position to the non-restricted position via the front action transmission mechanism 50A. As a result, the pallet PL can be pulled out of the storage bin 23 by the pallet pull-out portion 24R ( Fig. 13B ).

[0077] On the other hand, when the locking hook 63 is moved forward from the state where the front operating rod 41D is moved rearward by the operating cylinder 61 as described above ( Fig. 13B → Fig.13A ), the first swing piece 41M returns to its original position under the action of the force of the front force spring 41S, and the first fall-off prevention portion 41 and the second fall-off prevention portion 42 return from the non-restricted position to the restricted position. Therefore, it becomes impossible to extract the pallet PL from the storage bin 23 by the pallet extraction portion 24R. In addition, when the storage bin 23 is removed from the frame 22, when the pallet PL is about to fall out of the storage bin 23, this situation is prevented.

[0078] Thus, in this embodiment, when the storage bin 23 is mounted on the frame 22, the first fall-off prevention portion 41 and the second fall-off prevention portion 42 constituting the front pallet fall-off prevention mechanism 40A can be moved between the restricted position and the non-restricted position by operating the operating cylinder 61. At this time, the operating cylinder 61 is provided on the frame 22, and functions as an operating mechanism for moving one of the pair of fall-off prevention portions (the first fall-off prevention portion 41) of the storage bin 23 provided on the storage bin shelf 22T from the restricted position to the non-restricted position.

[0079] exist Fig. 12A , Fig. 12B In the embodiment, an access opening 22A is provided on the back side of the frame 22, which enables access to the storage bin 23 provided with the shelf 22T in the storage bin from the rear. When the operator OP accesses the storage bin 23 from the access opening 22A and inserts or removes the pallet PL relative to the storage bin 23, he or she operates the rear operating lever 43D provided on the third fall-off prevention part 43 (third swing piece 43M) constituting the rear pallet fall-off prevention mechanism 40B forward with one hand. As a result, the third fall-off prevention part 43 moves from the restricted position to the non-restricted position, and then the fourth fall-off prevention part 44 moves from the restricted position to the non-restricted position via the rear motion transmission mechanism 50B, so that the pallet PL can be inserted or removed from the storage bin 23.

[0080] Thus, in this embodiment, even after the storage bin 23 is set on the frame 22, the storage bin 23 can be accessed from the access opening 22A and the rear operating lever 43D can be operated with one hand, and the pallet PL can be plugged in and out (taken out and put in) relative to the storage bin 23.

[0081] Fig.14 is a block diagram showing a control system of the component assembly device 1. Figure 1 In the embodiment, the control device 70 of the component assembly device 1 is as follows: Fig.14 The control device 70 controls the operation of each part of the component assembly device 1 as shown. Specifically, the control device 70 controls the conveying of the substrate KB by the conveyor 12 and the positioning operation to the working position. In addition, the control device 70 controls the supply operation of the component BH by the tray feeder 13. In detail, the control device 70 controls the lifting operation of the extraction table 24 by the table lifting unit 25 and the moving operation of the pallet extraction unit 24R by the extraction table 24. In addition, the control device 70 controls the suction operation of the component BH by the assembly head 14 and the movement control of the assembly head 14 by the head moving mechanism 15.

[0082] When the component assembly device 1 performs the assembly operation of the component BH with respect to the substrate KB, the control device 70 first operates the conveyor 12 to receive and position the substrate KB supplied from the upstream process side at a predetermined position. After positioning the substrate KB, in order to be able to extract the pallet PL from the storage bin 23 mounted on the frame 22, the operating cylinder 61 corresponding to each storage bin 23 is operated to make the first and second fall-off prevention parts 41 and 42 of the front pallet fall-off prevention mechanism 40A constituting the storage bin 23 move from the restricted position to the non-restricted position ( Fig.13A → Fig. 13B ).

[0083] After the control device 70 moves the first fall-off prevention portion 41 and the second fall-off prevention portion 42 from the restricted position to the non-restricted position, the control device 70 extracts the pallet PL according to the above-mentioned method and places it on the upper surface ( Figure 5A → Figure 5B ), and then place the pallet PL at the component supply height ( Figure 1 and Figure 2 ). After the draw-out table 24 is located at the component supply height, the assembly head 14 can be used to pick up the component BH stored in the pallet PL. Therefore, the control device 70 moves the assembly head 14 to repeatedly perform an assembly cycle, which is composed of the following actions: a picking action to adsorb the component BH supplied by the tray feeder 13 to the adsorption nozzle 14N; and a component assembly action to assemble the component BH adsorbed by the adsorption nozzle 14N in the picking action on the substrate KB.

[0084] After all the components BH to be mounted on the substrate KB are mounted on the substrate KB by repeatedly executing the mounting round, the control device 70 operates the conveyor 12 to carry the substrate KB to the downstream process side. Thus, the component mounting operation for each substrate KB is completed.

[0085] As described above, in the present embodiment, the storage bin 23 includes a pair of fall-off prevention parts (the first fall-off prevention part 41 and the second fall-off prevention part 42 or the third fall-off prevention part 43 and the fourth fall-off prevention part 44) that can move freely between a restricted position that restricts the movement of the pallet PL from the pallet entrance and exit (the front entrance and exit 23F or the rear entrance and exit 23A) to the outside of the storage bin 23 and a non-restricted position that does not restrict the movement of the pallet PL, and includes a motion transmission mechanism (the front motion transmission mechanism 50A or the rear motion transmission mechanism 50B) that transmits the motion of moving the fall-off prevention part (the first fall-off prevention part 41 or the third fall-off prevention part 43) on one side from the restricted position to the non-restricted position to the fall-off prevention part (the second fall-off prevention part 42 or the fourth fall-off prevention part 44) on the other side, thereby moving the fall-off prevention part on the other side from the restricted position to the non-restricted position.

[0086] Therefore, in the present embodiment, when a pair of fall-off prevention parts are simultaneously positioned at the non-restricted position from the restricted position, it is sufficient to position the fall-off prevention part of one side from the restricted position to the non-restricted position. Therefore, it is sufficient to have a mechanism that moves only the fall-off prevention part of one side between the restricted position and the non-restricted position. Thus, the structure of the tray feeder 13 having a mechanism for extracting the pallet PL from the storage bin 23 can be simplified, thereby being able to achieve cost reduction while reliably preventing the pallet PL from falling from the storage bin 23. In addition, since the fall-off prevention part of the other side can be operated only by operating the fall-off prevention part of one side with one hand (i.e., a pair of fall-off prevention parts can be operated with one hand), the pallet PL can be efficiently plugged in and out of the storage bin 23 by manual operation.

[0087] The front motion transmission mechanism 50A constituting the front pallet fall-off prevention mechanism may be other structures as long as it transmits the motion of the first fall-off prevention part 41 moving from the restricted position to the non-restricted position to the second fall-off prevention part 42, thereby causing the second fall-off prevention part 42 to move from the restricted position to the non-restricted position. Fig.15 As shown in the modified example, the front motion transmission mechanism 50A is composed of a front connecting rod 151 extending in the left-right direction, and also as Fig.16A , Fig. 16BAs shown, a structure is obtained by pivoting one end to the rear end side of the first swinging piece 41M (the part behind the first pivot support pin 41P) and pivoting the other end to the front end side of the second swinging piece 42M (the part in front of the second pivot support pin 42P).

[0088] In such a structure, if Fig. 16B As shown, when the first swing piece 41M is swung in the counterclockwise direction R1 and is located from the restricted position to the non-restricted position, the second swing piece 42M is swung in the clockwise direction R3 via the front connecting rod 151, so as to be located from the restricted position to the non-restricted position. In this way, since the first swing piece 41M and the second swing piece 42M always swing in opposite directions, the pair of rod members (the first rod 41R and the second rod 42R) move in a manner of separating from or approaching each other, thereby being able to obtain the same effect as the case of the aforementioned embodiment.

[0089] Similarly, the rear motion transmission mechanism 50B constituting the rear pallet fall-off prevention mechanism 40B may be other structures as long as it transmits the motion of the third fall-off prevention part 43 moving from the restricted position to the non-restricted position to the fourth fall-off prevention part 44, thereby causing the fourth fall-off prevention part 44 to move from the restricted position to the non-restricted position. Fig.15 As shown in the modified example, the rear motion transmission mechanism 50B is composed of a rear connecting rod 155 extending in the left-right direction, and also as Fig.17A , Fig. 17B As shown, a structure is obtained by pivoting one end to the front end side of the third swinging piece 43M (the part in front of the third pivot support pin 43P) and pivoting the other end to the rear end side of the fourth swinging piece 44M (the part in the rear of the fourth pivot support pin 44P).

[0090] In such a structure, if Fig. 17B As shown, when the third swing piece 43M is swung in the counterclockwise direction R4 and is located from the restricted position to the non-restricted position, the fourth swing piece 44M is swung in the clockwise direction R6 via the rear connecting rod 155, so as to be located from the restricted position to the non-restricted position. In this way, since the third swing piece 43M and the fourth swing piece 44M always swing in opposite directions, the pair of rod members (the third rod 43R and the fourth rod 44R) move in a manner of separating from or approaching each other, thereby being able to obtain the same effect as the case of the aforementioned embodiment.

[0091] As described above, the component assembly device 1 of the present embodiment is constructed such that the storage bin 23 includes a pair of fall-off prevention parts (the first fall-off prevention part 41 and the second fall-off prevention part 42 or the third fall-off prevention part 43 and the fourth fall-off prevention part 44) that can move freely between a restricted position that restricts the movement of the pallet PL from the pallet entrance and exit (the front entrance and exit 23F or the rear entrance and exit 23A) to the outside of the storage bin 23 and a non-restricted position that does not restrict the movement of the pallet PL, and the storage bin 23 includes a motion transmission mechanism (the front motion transmission mechanism 50A and the rear motion transmission mechanism 50B) that transmits the motion of moving the fall-off prevention part (the first fall-off prevention part 41 or the third fall-off prevention part 43) on one side from the restricted position to the non-restricted position to the fall-off prevention part (the second fall-off prevention part 42 or the fourth fall-off prevention part 44) on the other side, thereby moving the fall-off prevention part on the other side from the restricted position to the non-restricted position.

[0092] Therefore, when the tray feeder 13 is capable of pulling out the pallet PL from the storage bin 23 and making a pair of fall-off prevention parts simultaneously move from the restricted position to the non-restricted position, it is sufficient to move one of the fall-off prevention parts from the restricted position to the non-restricted position. Therefore, only one operating mechanism (such as the aforementioned operating cylinder 61) is required to perform the operation of moving the fall-off prevention part of one side between the restricted position and the non-restricted position. Therefore, in the present embodiment, the structure of the tray feeder 13 having a mechanism for pulling out the storage bin 23 from the pallet PL can be simplified, thereby being able to reliably prevent the pallet PL from falling out of the storage bin 23 while achieving cost reduction. In addition, since the fall-off prevention part of the other side can be operated only by operating the fall-off prevention part of one side with one hand (that is, the pair of fall-off prevention parts can be operated with one hand), the pallet PL can be efficiently inserted and removed from the storage bin 23 by manual operation.

[0093] The embodiments of the present invention have been described so far, but the present invention is not limited to the above contents, and various modifications are possible. For example, in the above embodiments, the pair of rod members constituting the front pallet fall-off prevention mechanism 40A or the rear pallet fall-off prevention mechanism 40B is a structure that separates or approaches each other under the action of the swing of a pair of moving members (swinging pieces) swinging around the vertical axis relative to the storage bin 23. However, it can also be a structure as follows: the pair of rod members are installed on a pair of moving members that slide in the left and right directions relative to the storage bin 23, and separate or approach each other under the action of the movement of the left and right moving members separating or approaching each other.

[0094] In addition, in the above-mentioned embodiment, the storage bin 23 is configured to include both the front pallet fall-off prevention mechanism 40A and the rear pallet fall-off prevention mechanism 40B, but the storage bin 23 only needs to include at least one of the front pallet fall-off prevention mechanism 40A and the rear pallet fall-off prevention mechanism 40B. In addition, in the above-mentioned embodiment, the motion transmission mechanism (the front motion transmission mechanism 50A or the rear motion transmission mechanism 50B) is disposed on the upper surface side of the storage bin 23, but it may also be disposed on the lower surface side. Alternatively, it may also be disposed on both the upper surface side and the lower surface side. That is, the motion transmission mechanism only needs to be disposed on at least one of the upper surface side and the lower surface side of the storage bin 23.

[0095] The present invention provides a component assembly device, a tray feeder and a storage bin which can reliably prevent a pallet from falling off from a storage bin and achieve cost reduction.
