As shown in fig. 3 and 7, the guide body 38 includes: a groove portion 41 formed recessed on the upper surface of the base 16 and extending along the front and rear; and left and right rail plates 42, 42 fixed to the left and right sides of the groove 41 on the upper surface of the base 16 and extending toward the upper and left and right center portions of the groove 41. The guide body 38 includes a groove space 43 having a vertically inverted T-shaped cross section formed by the groove 41 and the pair of rail plates 42 and 42. The groove space 43 extends in the front-rear direction.
The reciprocating member 39 is formed in cooperation with the lower portion (lower body portion 25d) of the trunk portion 25 in the present embodiment. The reciprocating member 39 includes a lower portion of the body portion 25 accommodated between the pair of rail plates 42, and a pair of guide plates 44, 44 protruding from the lower portion of the body portion 25 along the left and right.
The positioning guide 36 guides the positioning member 22 so that the positioning member 22 can reciprocate. Further, although not shown, a driving device for reciprocating the positioning member 22 is provided above the turntable 11 independently of the cassette 13. A stopper 37 for determining a stop position at the time of reciprocating (at the time of forward and backward movements) of the positioning member 22 reciprocated by the driving device is provided to the guide main body 38 and the shuttle 39.
As shown in fig. 6, the stop device 37 includes: a plunger 46; a front concave portion 47 into which the tip end portion of the plunger 46 can be inserted and withdrawn; and a rear concave portion 48 which is capable of inserting and removing the tip end portion of the plunger 46 at a position rearward of the front concave portion 47. In the present embodiment, the plunger 46 is embedded in one of the portions of the base 16 that stand on the left and right with respect to the groove portion 41. Further, the distal end portion of the plunger 46 is in a state of protruding toward the groove portion 41 side. The plunger 46 further includes: a cylindrical plunger main body 46 a; a ball 46b internally disposed within the plunger body 46 a; and a spring 46c (compression coil spring) which is internally provided in the plunger main body 46a and which partially projects the ball 46b from the plunger main body 46a to the groove portion 41 side.
The front recess 47 and the rear recess 48 are formed on the surfaces of the pair of guide plates 44, 44 of the reciprocating member 39 that face the plunger 46 and are recessed at intervals in the front-rear direction. The position of the positioning member 22 when the distal end portion of the plunger 46 is fitted into the front concave portion 47 is referred to as a retreated position. The position of the positioning member 22 when the distal end portion of the plunger 46 is fitted into the rear concave portion 48 is referred to as an advanced position. When the positioning member 22 is in the retreated position, that is, in a state where the distal end portion (ball 46b) of the plunger 46 is fitted in the front concave portion 47, if a driving device (not shown) moves the positioning member 22 forward (advances), the ball 46b is separated from the front concave portion 47, and the ball 46b advances and is fitted in the rear concave portion 48, so that the positioning member 22 is in the advanced position. At this time, the distal end portions 26a of the side claws 26 and the distal end portions of the pull tab holding pieces 27 of the positioning member 22 are arranged above the stage 17, and the components of the slider 1 are positioned. In a state where the positioning member 22 is located at the forward position, that is, in a state where the distal end portion of the plunger 46 is fitted in the rear concave portion 48, when the driving device reciprocates (retreats) the positioning member 22, the ball 46b is fitted in the front concave portion 47, and the positioning member 22 becomes the retreated position. The tip end 26a of the side claw 26 and the tip end of the tab holder 27 are separated from above the stage 17.
As shown in fig. 2, 3, and 6, the stage 17 is a stage on which the body 2 of the slider 1 is placed. The outer shape of the front portion of the upper surface of the stage 17 is substantially the same as (identical or similar in shape and size to) the outer shape of the main body 2 in plan view. The rear portion of the upper surface of the stage 17 has a rectangular shape extending in the front-rear direction in plan view. Further, a lifting mechanism 18 guides the stage 17 so that the stage 17 can be lifted and lowered.
As shown in fig. 3, the elevating mechanism 18 includes at least an elevating guide 51, and the elevating guide 51 is fixed to the base 16 and guides the stage 17 so that the stage 17 can be elevated. In the present embodiment, the lifting mechanism 18 includes, in addition to the lifting guide 51: a lowering spring 52 that presses the stage 17 so as to lower the stage 17; and a lift stopper 53 which determines a lift range of the stage 17.
The lifting guide 51 includes: a lifter 55 extending in the up-down direction; and a guide body 56 that guides the lifter 55 so that the lifter 55 can move up and down. In the present embodiment, the elevating guide 51 fixes the elevating member 55 to the stage 17 and fixes the guide body 56 to the base 16.
As shown in fig. 3 and 5, the guide body 56 has a cylindrical shape penetrating in the vertical direction, more specifically, a square cylindrical shape. Further, the guide body 56 includes: a main block 57 having an opening 57a that opens forward in a plan view; and a sub-plate 58 fixed to the main block 57 and closing the opening 57a of the main block 57 from the front.
The main block 57 is fixed to the lower surface of the front portion of the base 16. Further, through holes 16h that open upward to the opening 57a of the main block 57 are formed in the left and right intermediate portions of the front portion of the base 16. The through hole 16h forms a lower part of a space for elevating the stage 17, and extends in the left-right direction and the rear direction with respect to the opening 57a in a plan view. The main block 57 further includes: a main block body 57s disposed on the lower side with respect to the base 16; and a fitting projection 57t that projects upward from the main block body 57s and is fitted into the through hole 16 h.
As shown in fig. 3 and 10 (c), the lifter 55 extends downward from the lower surface of the front portion of the stage 17, and has a vertical overall length longer than the overall length of the guide body 56. The lifter 55 has a prismatic shape corresponding to the inner surface shape of the guide body 56. Also, it is the elevation stopper 53 that determines the elevation range of the stage 17 disposed above the elevation member 55.
The up-down stopper 53 includes an up-down stopper 61 for determining a down-down limit position and an up-down stopper 59 for determining a up-down limit position.
The descent stopper 61 is constituted by the stage 17 and the guide main body 56 (main block 57). The stage 17 is vertically opposed to the main block 57, and the lowering limit position of the stage 17 is determined by collision. The lowering limit position of the stage 17 is a position where components of the slider 1 are fitted, and therefore, is sometimes referred to as an "fitting position".
The lift stopper 59 includes a projecting piece 63 projecting from the lower portion of the lifter 55 to the periphery, and a guide body 56 facing above the projecting piece 63.
The protruding piece 63 protrudes forward and backward from the lower portion of the lifter 55. The rear portion of the projecting piece 63 faces the lower side of the guide main body 56 (main block 57).
The rear portion of the protruding piece 63 faces the main block 57 in the vertical direction, and the lift limit position of the stage 17 is determined by collision. Incidentally, the extreme elevation position is a position where the upper surface of the stage 17 and the upper surface of the side block 19 are at the same height. This position is a position where the assembled slider 1 is discharged, and therefore, is sometimes referred to as "discharge position". Further, housed between the rear portion of the projecting piece 63 and the upper and lower portions of the guide body 56 is a lowering spring 52.
The descending spring 52 is a compression coil spring as shown in fig. 3, 4, and 10 (c). The upper portion of the descent spring 52 is housed in a downward hole 57h formed in the lower surface of the main block 57 of the guide body 56. The downward hole 57h is also opened at the rear surface of the guide body 56. To position the descent spring 52 accommodated in the downward hole 57h, the pin 64 protrudes upward from the rear portion of the protruding piece 63. The pin 64 is inserted into the inside of the descending spring 52 so that the descending spring 52 is positioned.
When the stage 17 is present at the mounting position, the lower portion of the lowering spring 52 protrudes downward from the downward hole 57h, and the rear portion of the protruding piece 63 is vertically separated from the guide main body 56 (main block 57). Further, in order to move the stage 17 from the mounting position to the discharge position, an elevation driving device for elevating the stage 17 against the restoring force of the lowering spring 52 is provided below the projecting piece 63 independently of the cassette 13, although not shown. A pair of side blocks 19 are disposed on the left and right of the stage 17 and above the base 16.
As shown in fig. 2 and 3, the side block 19 has a surface on the stage 17 side of the left and right side surfaces as a surface along the side surface of the stage 17. The pair of side blocks 19, 19 sandwich the stage 17 at the mounting position from the left and right by the opening and closing mechanism 21. Further, the surfaces of the upper portions of the pair of side blocks 19, 19 on the stage 17 side become a pair of inclined surfaces 19a, 19a that are separated in both right and left directions as they go upward. Therefore, the distance between the pair of side blocks 19 in the left-right direction is wider at the upper portion than at the lower portion, and the body 2 of the slider 1 can be easily put in.
The opening/closing mechanism 21 includes at least an opening/closing guide 66, and the opening/closing guide 66 is fixed to the base 16 and the side block 19 and guides the pair of side blocks 19, 19 so that the pair of side blocks 19, 19 can be opened and closed in the right and left directions. In addition, in the present embodiment, the opening/closing mechanism 21 includes, in addition to the opening/closing guide 66: an open/close stopper 67 for determining an open/close range of the pair of side blocks 19, 19; a closing spring 68 that presses the pair of side blocks 19, 19 so as to close (approach) the pair of side blocks 19, 19; a transmission device 69 that converts upward movement into left-right movement, transmits the movement to the pair of side blocks 19, and opens (separates) the pair of side blocks 19, 19; and a transmission lowering spring 71 that generates a downward force in such a manner as to restrict the upward movement of the transmission 69.
As shown in fig. 2, the opening/closing guide 66 includes an opening/closing member 72 that moves in the left-right direction, and a guide body 73 that guides the opening/closing member 72 so that the opening/closing member 72 can move in the left-right direction. In the present embodiment, the guide body 73 is fixed to the upper surface of the front portion of the base 16 and extends in the left-right direction. In addition, the guide body is provided with grooves (reference numerals omitted) extending along the left and right at the front and rear surfaces. The shutter 72 is shaped to cover the guide body 73 from the upper surface and sandwich the upper portion of the guide body 73 from the lower side (groove) thereof. The shutter 72 projects downward from the side block 19. Also, it is the opening/closing stopper 67 that determines the moving range of the side block 19 in the left-right direction.
The open/close stopper 67 includes a close stopper 75 that determines a closed position (approaching limit position) of the pair of side blocks 19, and an open stopper 76 that determines an open position (separating limit position) of the pair of side blocks 19, 19.
As shown in fig. 2 and 4, the closing stopper 75 is composed of the stage 17 and a pair of side blocks 19 and 19. The stage 17 and the left side block 19 oppose each other in the left-right direction, and the stage 17 and the right side block 19 oppose each other in the left-right direction, and the closed position of the side blocks 19 is determined by collision. Incidentally, the stage 17 is opposed to the pair of side blocks 19, 19 in the left-right direction over the entire lifting range. Further, the opening stopper 76 is detailed later. Further, a closing spring 68 presses the pair of side blocks 19, 19 so as to close the pair of side blocks 19, 19 with the stage 17 interposed therebetween (so as to approach the stage 17 in the left-right direction).
The closing spring 68 is a compression coil spring as shown in fig. 2 and 6. Further, a perforated piece 78 that houses the closing spring 68 protrudes downward from the lower surface of the side block 19 at a position rearward of the shutter 72 of the opening-closing guide 66. The apertured member 78 is in the form of a block. Further, a housing hole 78h for housing the closing spring 68 is formed in a surface of the left and right side surfaces of the holed member 78 opposite to the stage 17. The housing hole 78h is formed to surround the closing spring 68 from the outer peripheral side of the closing spring 68. On the other hand, a pressing plate 79 that presses the closing spring 68 from the surface on the opposite side to the stage 17 is fixed to the side surface in the front portion of the base 16. The closing spring 68 accommodated in the accommodating hole 78h is accommodated in a state of being contracted in the left-right direction by the pressing plate 79. The platen 79 faces the holed member 78 on the opposite side of the stage 17 from the holed member 78. Thus, the holed member 78 and the pressure plate 79 are in a positional relationship capable of colliding, and thus constitute the opening stopper 76.
In addition, the closing spring 68 urges the side block 19 in the left-right direction toward the stage 17 with its restoring force. Although not shown, an opening drive device for opening the pair of side blocks 19 and 19 against the restoring force of the closing spring 68 is disposed below the set cassette 13 independently of the set cassette 13. Further, what converts the upward movement of the opening drive means into a movement in the left-right direction to transmit to the pair of side blocks 19, 19 and to open (separate) the pair of side blocks 19, 19 is a transmission means 69.
As shown in fig. 2, 3, and 5, the transmission device 69 includes: a drive cam 81 that is displaced in the vertical direction and is pressed downward by the transmission lowering spring 71; a driven cam 82 that is pushed by the rising drive cam 81 to be displaced in the left-right direction together with the pair of side blocks 19, 19; a drive cam guide 83 fixed to the base 16 and guiding the drive cam 81 such that the drive cam 81 can be raised and lowered; and a descent stopper 84 that determines a descent limit position of the drive cam 81.
The driven cam 82 is a portion facing the stage 17 side in the right and left side portions of the holed member 78. The driven cam 82 is further away from the stage 17 than the surface facing the stage 17 among the left and right side surfaces of the side block 19. That is, a drive cam space 86 is formed between the stage 17 side surface of the left and right side surfaces of the driven cam 82 and the stage 17. The drive cam space 86 is formed on the left and right of the stage 17 and accommodates the drive cam 81.
The drive cam 81 extends in the up-down direction. The upper portion of the drive cam 81 contacts the lower portion of the driven cam 82 along left and right surfaces 81a and 82a (hereinafter referred to as contact surfaces). Contact surfaces 81a and 82a between the upper portion of the drive cam 81 and the driven cam 82 are inclined surfaces inclined so as to approach the stage 17 as going upward. As shown in fig. 2 and 5, the base 16 is formed with a through hole 16c extending in the vertical direction through which the drive cam 81 is inserted into the drive cam space 86 from below the base 16. Further, a through hole 57b extending in the vertical direction through which the drive cam 81 passes is formed in the main block 57 of the up-down guide 51 at a position corresponding to the through hole 16c of the base 16. Further, a driving cam guide 83 for guiding the pair of driving cams 81 and 81 so that the pair of driving cams 81 and 81 can move up and down.
As shown in fig. 2 and 3, the drive cam guide 83 includes a transmission member 87 extending in the vertical direction and a guide body 88 for guiding the transmission member 87 so that the transmission member 87 can move up and down. In the present embodiment, the drive cam guide 83 has the transmission member 87 fixed to the pair of drive cams 81, and the guide body 88 fixed to the lower surface of the base 16.
The transmission member 87 is in the present embodiment in a plate shape having a thickness direction in the front-rear direction. The transmission member 87 has a pair of drive cams 81 and 81 projecting upward from the left and right sides of the upper surface of the transmission member 87.
The guide body 88 is the guide body 56 (main block 57) of the elevating guide 51, and the transmission member 87 is guided from the front surface and the rear surface of the transmission member 87. A guide hole 57c for guiding the transmission member 87 so that the transmission member 87 can be raised and lowered is formed in the rear portion of the lower surface of the main block 57. The guide hole 57c penetrates along the left and right sides, and communicates with a through hole 57b through which the drive cam 81 penetrates. Further, the front surface portion of the guide hole 57c and the front surface of the transmission piece 87 are fitted to each other by a concave portion and a convex portion extending in the vertical direction so that the transmission piece 87 can be lifted and lowered, so that the transmission piece 87 is not displaced in the left and right direction in the guide hole 57 c. Incidentally, fig. 5 shows a case where a convex portion 87a is formed on the front surface of the transmission member 87. A descent stopper 84 that prevents the transmission member 87 from falling and determines a descent limit position of the drive cam 81 is fixed to a lower surface of the main block 57.
The descent stopper 84 is shaped to support the transmission member 87 from below at a position above the lower end of the transmission member 87. The transmission member 87 is formed in a shape in which the upper portion protrudes in both right and left directions with respect to the lower portion. Therefore, the upper portion of the transmission member 87 is provided with lower end surfaces on both left and right sides. The descent stopper 84 is formed in a frame shape so as to support left and right lower end surfaces in an upper portion of the transmission member 87 from below and guide a lower portion of the transmission member 87 so as to be displaceable in the vertical direction. Incidentally, the front side of the frame-shaped descent stopper 84 becomes the opening 84 a. As shown in fig. 4, a downward hole 57h for accommodating the lowering spring 52 of the elevating mechanism 18 is disposed directly above the opening 84 a. The opening 84a is not in contact with the descending spring 52 and the rear portion of the projecting piece 63 of the ascending stopper 59. A transmission lowering spring 71 presses downward a transmission member 87 supported from below by the lowering stopper 84.
The transmission lowering spring 71 is housed between the main block 57 and the transmission member 87 in the vertical direction as shown in fig. 2. A downward hole 57i for accommodating the transmission lowering spring 71 is formed in the lower surface of the main block 57. In the illustrated example, two downward holes 57i, 57i are formed in the lower surface of the base 16 so as to be spaced apart from each other in the left-right direction. The transmission lowering spring 71 is housed in the upper surface of the transmission member 87 and the two downward holes 57i and 57i on the upper side thereof in a contracted state, and generates a downward force to restrict the upward movement of the transmission member 87. When the transmission member 87 collides with the descent stopper 84, the pair of side blocks 19 and 19 are brought into a closed state in which they sandwich the stage 17 by the restoring force of the closing spring 68.
The set box 13 is controlled to stop at 8 stop points as described above, and at several stop points, the robot arm feeds the components of the slider 1 onto the stage 17 of the set box 13.
As shown in fig. 9 (a), the main body 2 is supplied from directly above the stage 17 at the 1 st stop point. At this time, the driving device for the opening and closing mechanism is operated to raise the transmission member 87, and the transmission device 69 converts the upward movement of the transmission member 87 into the movement in the left-right direction to separate the pair of side blocks 19, 19 from the stage 17 and set the state to the open state. In addition, the stage 17 exists at the mounting position (the descent limit position). When the main body 2 is supplied, as shown in fig. 9 (B), the driving device for the opening/closing mechanism is separated from the transmission member 87, and the pair of side blocks 19 and 19 approach the stage 17 by the restoring force of the closing spring 68, thereby being in the closed state. When the dimension of the main body 2 in the left-right direction is slightly smaller than the dimension of the stage 17 in the left-right direction, the main body 2 is accommodated between the pair of side blocks 19, 19 in a state capable of being slightly moved. When the dimension of the main body 2 in the left-right direction is slightly larger than the dimension of the stage 17 in the left-right direction, the main body 2 is sandwiched between the pair of side blocks 19, 19. Incidentally, at the 1 st stop point, the positioning member 22 exists at a retreated position that is away from the stage 17 in the rearward direction.
Next, as shown in fig. 9 (C), the tab 3 is supplied onto the body 2 at the 2 nd stop point, and the annular portion 3a of the tab 3 is penetrated by the front cover fixing portion 9. Thereafter, the drive device for the pusher support mechanism of the positioning member 22 is operated to raise the distal end portion of the tab pusher 27 as shown in fig. 10 (a). Then, when the drive device for the shuttle 23 is operated to advance the positioning member 22 to the advanced position as shown in fig. 10 (B), and the tip end portion of the tab presser 27 reaches the position directly above the tab 3, the drive device for the presser support mechanism is operated so as to be separated from the tab presser 27, and the tab 3 is pressed by the tip end portion of the tab presser 27. At this time, the distal end portion 26a of the side claw 26 is inserted into the body 2, and the body 2 is positioned.
This state is maintained at the 3 rd stop point and the 4 th stop point. Further, at the 4 th stop point, the cover 4 is supplied directly above the pair of cover fixing portions 9, 9. At the 5 th stop point, the drive device for the pressing member support mechanism of the positioning member 22 is operated to raise the tip end portion of the tab pressing member 27, and in this state, the cover 4 is fastened and fixed to the pair of cover fixing portions 9, 9. Thereafter, the drive device for the pressing member support mechanism is operated to separate from the tab pressing member 27, and the tab 3 is pressed by the tip end portion of the tab pressing member 27. Thereafter, at the 6 th stopping location, the state at the 5 th stopping location is substantially maintained. Further, the positioning member 22 may be retracted to an intermediate position between the forward position and the backward position by operating a driving device for the reciprocating mechanism 23.
At the 7 th stop point and the 8 th stop point, the drive device for the shuttle 23 is operated to retreat the positioning member 22 to the retreated position as shown in fig. 10 (C), and the tab presser 27 and the side pawl 26 are separated from the slider 1. Further, as shown in fig. 11, the stage 17 is raised to the discharge position by operating the driving device for the elevating mechanism. In the ejecting position, the upper surface of the stage 17 and the upper surface of the side block 19 are at the same height, and therefore, the slider 1 can be gripped by the robot arm and ejected.
Since the set box 13 according to the first embodiment of the present invention described above includes the opening/closing guide 66, the left-right interval between the pair of side blocks 19, 19 is widened by displacing the pair of side blocks 19, 19 to the opened position, the left-right interval between the pair of side blocks 19, 19 can be made wider than the left-right dimension of the predetermined main body 2 to be supplied, and the main body 2 can be supplied onto the stage 17 from above.
In the placement box 13 according to the first embodiment, the pair of side blocks 19 and 19 are displaced to the closed position, so that the left-right distance between the pair of side blocks 19 and 19 is narrowed, and the movement of the main body 2 in the left-right direction is restricted by the pair of side blocks 19 and 19, thereby stabilizing the posture of the main body 2 on the stage 17.
Further, since the set box 13 of the first embodiment includes the stage 17 that can be lifted and lowered, the body 2 can be projected upward with respect to the pair of side blocks 19, 19 by simply lifting the stage 17, and the assembled slider 1 can be discharged by the projected portion. Incidentally, with the set box 13 of the first embodiment, at the rising limit position of the stage 17, the height of the upper surface of the stage 17 is the same as the height of the upper surface of the side block 19, and therefore, the assembled slider 1 is easily ejected.
Further, since the set cassette 13 according to the first embodiment is attached to the turn table 11, when the slider 1 to be attached is changed, the set cassette 13 according to the shape and size of the changed slider 1 may be attached to the turn table 11 instead, and the turn table 11 does not have to be replaced.
Further, since the mounting box 13 of the first embodiment includes the side claws 26 and the tab holders 27, the body 2 and the tabs 3 can be stabilized during assembly, and the assembly accuracy can be improved. Further, since the cassette 13 according to the first embodiment is independent of the driving device, the size of the cassette 13 can be reduced compared to the case where the cassette is integrated with the driving device.
As shown in fig. 12, the set cassettes 13 are placed on the outer peripheral portion of the upper surface of the turntable 11 having a disk shape at equal intervals. In order to determine the position for placing the cassette 13, as shown in fig. 16 (B), a positioning portion 91 is formed on the turntable 11 and the cassette 13. In the present embodiment, the turntable 11 includes a disc-shaped table main body 11a, and a projection 92 projecting upward from the upper surface of the table main body 11 a. The base 16 of the storage box 13 has a recess (not shown) on its lower surface into which the projection 92 is fitted. The cassette 13 positioned by the positioning portion 91 including the convex portion 92 and the concave portion is fixed to the turntable 11 by the coupling device 14.
As shown in fig. 13 and 14, the coupling device 14 includes: a fixed block 101 fixed to the turntable 11 (table main body 11 a); a 1 st shaft 102 supported by the fixed block 101; an arm 103 extending in a radial direction around the 1 st axis 102 and rotatable around the 1 st axis 102; a 2 nd shaft 104 extending from a distal end portion of the arm 103 in a direction intersecting the longitudinal direction of the arm 103; a lever 105 which can rotate around the 2 nd axis 104 and which clamps the base 16 of the cassette 13 in cooperation with the turntable 11; a lever spring 106 which is penetrated between the 1 st shaft 102 and the 2 nd shaft 104 by the arm 103; a washer 107 for pressing the base 16 downward by the rod 105, which is inserted through the arm 103 and sandwiched between the rod spring 106 and the rod 105; and a posture determining unit 108 for determining the posture of the arm 103 rotating about the 1 st axis 102 when the mounting box 13 is coupled to the base 16.
The fixed block 101 includes a front block 111 and a rear block 112 facing each other in the front-rear direction, and a middle block 113 extending between the lower portion of the front block 111 and the lower portion of the rear block 112. Both end portions of the 1 st shaft 102 are rotatably supported by the front block 111 and the rear block 112.
The 1 st axis 102 extends horizontally. Further, an arm 103 is fixed to an intermediate portion of the 1 st shaft 102. Therefore, the arm 103 is integrated with the 1 st shaft 102, and the arm 103 can rotate about the 1 st shaft 102.
Further, the arm 103 extends in a radial direction around the 1 st axis 102. Therefore, one end of the arm 103 is fixed to the 1 st shaft 102, and the other end (tip end) of the arm 103 is separated from the 1 st shaft 102. The longitudinal direction of the arm 103 coincides with the radial direction around the 1 st axis 102. The arm 103 penetrates the lever spring 106 and the washer 107 in this order from the one end side toward the other end side.
The rod spring 106 is a compression coil spring. An arm 103 penetrates inside the lever spring 106. The 2 nd shaft 104 is fixed to a portion of the arm 103 that protrudes to the opposite side of the 1 st shaft 102 with respect to the lever spring 106 and the washer 107, that is, a distal end portion of the arm 103.
The 2 nd axis 104 extends in a direction orthogonal to the longitudinal direction of the arm 103 and parallel to the 1 st axis 102. The 2 nd shaft 104 extends in a radial direction around the arm 103. Therefore, the 2 nd shaft 104 has a longitudinal middle portion thereof penetrated and fixed by the arm 103, and longitudinal both end portions of the 2 nd shaft 104 extend so as to be spaced apart from the arm 103. The rods 105 are rotatably supported at both ends of the 2 nd shaft 104.
The rod 105 includes: a cam portion 115 that rotates about the 2 nd shaft 104 and clamps the base 16 in cooperation with the turntable 11; and an operating portion 116 extending from the cam portion 115.
The cam portion 115 includes a pair of plate cams 117, 117 penetrated by both end portions in the longitudinal direction of the 2 nd shaft 104. The operation portion 116 extends from the pair of plate cams 117, 117 in a radial direction around the 2 nd shaft 104. The direction in which the operation portion 116 extends is the longitudinal direction of the rod 105.
A rotation hole 117h through which the 2 nd shaft 104 is rotatably inserted is formed in the center of the plate cam 117. The distance between the center of the rotation hole 117h (2 nd shaft 104) and the outer periphery of the plate cam 117 (cam portion 115) is not constant. The longitudinal direction of the rod 105 is extended at right angles to the longitudinal direction of the arm 103, and the posture of the rod 105 at this time is set to the 1 st posture. The longitudinal direction of the rod 105 is made to coincide with the longitudinal direction of the arm 103, and the posture of the rod 105 at this time is set to the 2 nd posture. In the 1 st posture, the shortest distance between the outer periphery of the cam portion 115 and the 1 st shaft 102 is shorter than that in the 2 nd posture. When the set cassette 13 is detached from the turntable 11, the lever 105 assumes the 2 nd posture. On the other hand, when the cassette 13 is coupled to the turntable 11, the lever 105 assumes the 1 st posture, and the arm 103 assumes a posture extending upward from the 1 st shaft 102 in a straight line (upright posture). Further, it is the posture determining section 108 that positions the arm 103 in the upright posture.
The posture determining unit 108 is constituted by a collision member 119 inserted between the 1 st shaft 102 and the rod spring 106 by the arm 103 and the middle block 113 which is collided by the collision member 119.
The collision member 119 is fixed in contact with the 1 st shaft 102. A flat portion 121 is formed on the outer peripheral surface of the intermediate portion in the longitudinal direction of the 1 st shaft 102 so that the striker 119 makes surface contact therewith. To be more specific, the 1 st axis 102 has a shape in which the middle portion in the longitudinal direction thereof is cut along a plane parallel to the axial direction of the cylinder. More specifically, the 1 st shaft 102 includes, in its longitudinal intermediate portion: a planar portion 121 extending parallel to the longitudinal direction of the 1 st shaft 102; and a curved surface portion 122 that connects both ends of the planar portion 121 in an arc shape when viewed from the longitudinal direction of the 1 st shaft 102, and the arc is shaped to extend parallel to the longitudinal direction of the 1 st shaft 102.
One end of the arm 103 extending in a direction perpendicular to the plane portion 121 is embedded in the plane portion 121 at the middle portion of the 1 st shaft 102 in the longitudinal direction. Further, the arc of the curved surface portion 122 is a shape larger than a semicircle.
A corner portion of the middle block 113, which is formed by one of the left and right side surfaces and the upper surface, is formed with a corner recess 113a recessed along the curved surface portion 122 of the 1 st shaft 102 so as to have an arc-shaped cross section. In addition, the collision member 119 collides with a portion of the upper surface of the middle block 113 adjacent to the angular recess 113a, positioning the arm 103 in the upright posture. The upper surface of the middle block 113 is located below the upper surfaces of the front block 111 and the rear block 112. A space 123 for accommodating the striker 119 between the front block 111 and the rear block 112 is formed above the middle block 113.
Further, a washer 107 is disposed between the cam portion 115 and the rod spring 106. The washer 107 has a through hole 107h through which the arm 103 passes. The washer 107 is radially outwardly extended from the rod spring 106. The washer 107 is pressed against the cam portion 115 by the elastic force of the lever spring 106. The gasket 107 presses the base 16 of the cassette 13 against the turntable 11.
As shown in fig. 16 (B), the base 16 includes a coupling portion 16t that is pressed by the washer 107 and coupled by the coupling device 14. An access hole 16u through which the arm 103 can be accessed is formed in the connection portion 16t, and the access hole 16u penetrates in the vertical direction and opens laterally. Incidentally, as shown in fig. 5, the base 16 includes: a base body 16r on which a rail plate 42 of the positioning reciprocating mechanism 23 is placed; a pair of base sub-bodies 16s, 16s extending left and right on the front side of the base main body 16r and on which a guide body 73 of the opening/closing guide 66 is placed; and a connecting portion 16t that is shaped to extend laterally from the base main body portion 16 r. A through hole 16h is formed between the pair of base sub-bodies 16s, 16 s.
As shown in fig. 16 (B), a hole 11h for embedding the fixed block 101 is formed in the upper surface of the turntable 11 (table main body 11 a). The coupling device 14 is in a state where the fixed block 101 is embedded in the hole 11h of the turntable 11 and the rod 105 is disposed above the turntable 11.
The above-described coupling device 14 is used in the following order.
As shown in fig. 15 (a), the lever 105 is in the 1 st posture in a state where the cassette 13 and the turntable 11 are coupled by the coupling device 14. At this time, the lever 105 is in a horizontal state, and the coupling portion 16t of the base 16 is pressed against the turntable 11 via the washer 107 by the cam portion 115. At this time, the posture of the arm 103 is an upright posture.
Next, as shown in fig. 15 (B), when the lever 105 is rotated about the 2 nd shaft 104 to bring the lever 105 into the 2 nd posture, the state in which the washer 107 is in close contact with the coupling portion 16t of the base 16 is released, and the washer 107 is brought into a state in which it is separated upward from the coupling portion 16t by the elastic force of the lever spring 106.
Next, as shown in fig. 16 (a), the lever 105 is rotated about the 1 st axis 102 so that the lever 105 is separated from the position directly above the connection portion 16t, and the posture of the arm 103 is brought into a fallen posture.
Thereafter, the set cassette 13 is raised as shown in fig. 16 (B). In this way, the cassette 13 can be replaced with another cassette.
In the attachment mechanism 15 of the cassette 13 according to the first embodiment of the present invention, the shortest distance between the outer periphery of the cam portion 115 and the 1 st shaft 102 can be changed by simply operating the lever 105, and therefore, the turntable 11 and the base 16 can be easily connected and disconnected.
The attachment mechanism 15 of the cassette 13 according to the first embodiment pivots the lever 105 about the 1 st axis 102 to change the posture of the arm 103 from the upright posture to the fallen posture, or vice versa. In order that the washer 107 does not become an obstacle due to the relationship with the base 16 (the coupling portion 16t) when the posture of the arm 103 is changed in this manner, the lever spring 106 presses the washer 107 outward in the radial direction about the 1 st shaft 102, and therefore the attachment mechanism 15 of the cassette 13 according to the first embodiment can easily operate the lever 105.
In addition, the attachment mechanism 15 of the set box 13 according to the first embodiment can produce a predetermined slider 1 by preparing any type of set box 13 according to the first embodiment corresponding to the body 2 to be attached and replacing the set box 13 according to the slider 1 to be produced, and can be a useful mechanism that does not require a conventional ring surrounding the turn table 11 without replacing the turn table 11.
The present invention is not limited to the above-described embodiments, and can be modified as appropriate within a scope not departing from the gist thereof. For example, in the above-described embodiment, the ejecting position of the assembled slider 1 (the lift limit position of the stage 17) is the same height position as the upper surface of the side block 19, but the present invention is not limited to this, and may be a different height position, that is, a position higher than the upper surface of the side block 19 or a position lower than the upper surface of the side block 19. Even in the case of different height positions, the slider 1 placed on the upper surface of the stage 17 at the lift limit position of the stage 17 is in a state of being at least partially projected with respect to the side block 19, and the slider 1 can be ejected by the projected portion.
