(Function)
Next, the operation | work which fastens the set screw 16 to the product 16 using this set screw fastening apparatus 10 is demonstrated.

  As shown in FIG. 25, first, the main body portion 23 (third cylinder 102) that is movable in the horizontal direction when the driving force is transmitted from the first cylinder 56 has a horizontal end portion (the right end portion shown in FIG. 25). ).

  Further, as shown in FIGS. 18 and 20, the supply tray 52 is in a rearwardly inclined state in which the insertion portion 52 </ b> A is positioned below the insertion portion 52 </ b> B in the vertical direction. Then, the operator puts a plurality of set screws 14 into the replenishing unit 20 from the replenishing port 30 </ b> A of the hopper member 30. In this state, since the discharge port 32A of the transport pipe 32 is closed by the closing lid 36 (closed state), the set screw 14 supplied to the supply unit 20 is not discharged from the discharge port 32A of the transport pipe 32. .

  Further, as shown in FIGS. 19 and 21, the pressing member 50 to which the driving force is transmitted from the third cylinder 102 moves downward in the vertical direction and presses the upper end portion of the swing arm 46 downward. When the upper end portion of the swing arm 46 is pressed downward, the swing arm 46 and the swing arm 44 swing about the rotation shaft 44A.

  As the swing arm 44 swings, the vertically moving arm 42 moves upward in the vertical direction, whereby the swing arm 40 swings about the rotation shaft 40A. Then, the closing lid 36 fixed to the end of the swing arm 40 moves downward to open the discharge port 32A (open state).

  When the discharge port 32A is opened, the set screw 24 supplied to the supply unit 20 is discharged from the discharge port 32A by gravity and is supplied to the input unit 52A of the supply tray 52 (see FIG. 1).

  13 and 15, after the set screw 24 is inserted into the insertion portion 52A of the supply tray 52, the main body portion 23 (third cylinder 102) to which the driving force from the first cylinder 56 is transmitted. ) Move to the second position.

  Further, as shown in FIGS. 14 and 17, the pressing member 50 to which the driving force is transmitted from the third cylinder 102 moves downward in the vertical direction and presses the upper end portion of the vertical movement arm 74E downward. When the upper end of the vertically moving arm 74E is pressed downward, the pair of swing arms 74D swings around the rotation shaft 74C. As the swing arm 74D swings, the vertical movement arm 74B moves upward in the vertical direction, and the rod 74A attached to the lower end of the vertical movement arm 74B also moves upward in the vertical direction.

  As the rod 74 </ b> A moves upward in the vertical direction, the base plate 68 and the second cylinder 54 swing around the hinge 70. Then, the supply tray 52 shifts to a forward inclined state in which the input portion 52A is positioned vertically above the insertion portion 52B.

  Further, the vibrator 76 vibrates the supply tray 52 that shifts from the backward inclined state to the forward inclined state. That is, the supply tray 52 swings while vibrating.

  As shown in FIG. 2, the supply tray 52 shifts from the backward tilted state to the forward tilted state while vibrating, so that the set screw 14 lying down is guided to the insertion portion 52B by gravity while rising. Accordingly, the set screw 14 is inserted into the insertion hole 60 formed in the insertion portion 52B.

  As shown in FIG. 13 and FIG. 15, when a predetermined time elapses when the supply tray 52 is tilted forward, the pressing member 50 to which the driving force is transmitted from the third cylinder 102 moves upward in the vertical direction. . As the pressing member 50 moves upward in the vertical direction, the pressing force applied to the vertical movement arm 74E is released, and the supply tray 52 returns to the initial state. That is, the supply tray 52 shifts from the forward tilt state to the rear tilt state.

  As shown in FIG. 3, when the supply tray 52 shifts from the forward tilted state to the rearward tilted state, the set screw 14 guided to the insertion portion 52B and not inserted into the insertion hole 60 is moved to the insertion portion 52A by gravity. It moves and is collected by the input part 52A.

  Further, as shown in FIG. 16, the pressing member 50 to which the driving force is transmitted from the third cylinder 102 moves downward in the vertical direction and presses the upper end portion of the vertical movement arm 74E downward. Note that the amount of pressing this time is smaller than the amount of pressing when the supply tray 52 is tilted forward.

  When the upper end of the vertically moving arm 74E is pressed downward, the pair of swing arms 74D swings around the rotation shaft 74C. As the swing arm 74D swings, the vertical movement arm 74B moves upward in the vertical direction, and the rod 74A attached to the lower end of the vertical movement arm 74B also moves upward in the vertical direction.

  As the rod 74 </ b> A moves upward in the vertical direction, the base plate 68 and the second cylinder 54 swing around the hinge 70. Then, the supply tray 52 shifts to a horizontal state where the height of the insertion portion 52A and the height of the insertion portion 52B are the same (see FIG. 4).

  In this state, as shown in FIG. 24, the main body portion 23 to which the driving force is transmitted from the first cylinder 56 moves in the horizontal direction, and the portion where the set screw 14 is fastened first in the product 16 and the supply tray 52. Corresponds to the horizontal position. Even if the main body 23 moves in the horizontal direction, the horizontal state of the supply tray 52 and the second cylinder 54 is maintained by a jig (not shown).

  When the position where the set screw 14 is first fastened in the product 16 and the horizontal position of the supply tray 52 correspond to each other, the supply to which the driving force is transmitted from the second cylinder 54 as shown in FIGS. The tray 52 moves to the near side in the depth direction together with the support plate 62 attached to the lower surface of the supply tray 52. The sensors 94 and 96 detect the presence / absence of the set screw 14 in the insertion hole 60 formed in the moving supply tray 52 and the vertical state of the set screw 14.

  First, the case where the up-and-down direction of the set screw 16 inserted into the insertion hole 60 at the distal end that reaches the upper side of the product 16 first is appropriate will be described.

  As shown in FIGS. 7 and 8, when the sensor 94 and the sensor 96 determine that the set screw 14 inserted into the insertion hole 60 at the distal end is in an up / down state, the set screw 14 in the up / down state is appropriate. , The control unit 98 controls the second cylinder 54 and the third cylinder 102 to move the block 104 and the power tool 114 downward.

  Thereby, the inclined surface 104A of the block 104 presses the inclined surface 86A, and the moving member 86 and the gate-shaped member 90 move to the back side in the depth direction. When the moving member 86 and the gate-shaped member 90 are moved to the back side in the depth direction, the rod 62A is pressed to the back side in the depth direction by the leg portion 90A of the gate-shaped member 90, and the support plate 62 is pressed against the supply tray 52. Moves to the depth side in the depth direction (see FIG. 5).

  As a result, the support plate 62 moves from the support position to the supply position, and the set screw 14 inserted into the insertion hole 60 located above the product 16 is supplied to the product 16.

  Then, the lower end of the bit 116 provided in the electric power tool 114 moved downward simultaneously with the block 104 is inserted into a hexagonal hole provided in the set screw 14, and the set screw 14 is moved to the product 16 by rotating the bit 116. It is concluded.

  As shown in FIG. 9, when the set screw 14 is fastened to the product, the control unit 98 moves the block 104 and the power tool 114 upward. As a result, the inclined surface 104A is separated from the inclined surface 86A of the moving member 86, and the moving member 86 and the portal member 90 are moved to the near side in the depth direction by the urging force of the compression coil spring 92. As a result, the rod 62A and the leg portion 90A of the portal member 90 are separated from each other.

  When the set screw 14 is fastened to a portion where the set screw 14 is fastened first, the main body 23 to which the driving force is transmitted from the first cylinder 56 moves in the horizontal direction, and the second set screw 14 in the product 16. The position in the horizontal direction of the supply tray 52 corresponds to the part where the is fastened.

  Next, in the plurality of insertion holes 60, the set screw 14 inserted into the insertion hole 60 at the tip that reaches the upper side of the product 16 first and the insertion hole that reaches the upper side of the product 16 secondly. A case where the vertical direction of the set screw 14 inserted in 60 is inappropriate will be described.

  As shown in FIG. 10 and FIG. 11, when the sensor 94 and the sensor 96 determine that the set screw 14 inserted into the insertion hole 60 is in the up / down state, the set screw 14 in the up / down state is not appropriate. When moving upward of the product 16, the control unit 98 does not move the block 104 downward. Thereby, the support plate 62 of the set screw 14 inserted in the insertion hole 60 located above the product 16 does not move from the support position to the supply position.

  Then, in this state, the second cylinder 54 moves the supply tray 52 to the near side in the depth direction, so that the rod 62A hits the leg portion 90A and the movement of the support plate 62 is restricted. Moves to the near side in the depth direction. As a result, after the set screw 14 having an inappropriate vertical state passes over the product 16, the support plate 62 of the insertion hole 60 into which the inappropriate set screw 14 has been inserted moves from the support position to the supply position. Then, the set screw 14 whose vertical state is inappropriate is discharged to the outside of the insertion hole 60. In this way, the two set screws 14 are discharged to the outside.

  Furthermore, as shown in FIG. 12, when the sensor 94 and the sensor 96 determine that the vertical direction of the set screw 14 inserted into the insertion hole 60 that reaches the upper side of the product 16 third is appropriate, When the proper set screw 14 moves upward of the product 16, the control unit 98 controls the third cylinder 102 to move the block 104 and the electric tool 114 downward, and the set screw 14 is moved according to the procedure described above. Is fastened to the product 16.

  When the set screw 14 is fastened to the product 16, the main body 23 to which the driving force is transmitted from the first cylinder 56 moves in the horizontal direction. The horizontal position of the supply tray 52 corresponds to the portion of the product 16 where the set screw 14 is fixed second.

  As described above, when the supply tray 52 is tilted forward while being vibrated by the vibrator 76, the set screw 14 that has been lying up rises and the set screw 14 is efficiently inserted into the insertion hole 60.

  Further, as described above, since the set screw 14 is efficiently inserted into the insertion hole 60 by using the vibrator 76, the set screw can be configured with a simpler configuration than the configuration without the vibrator 76. Are supplied separately.

  Further, after the supply tray 52 is tilted forward, the set screw 14 that has not been inserted into the insertion hole 60 is recovered by the insertion portion 52A by further tilting backward.

  Further, since the control unit 98 moves the support plate 62 from the support position to the supply position based on the detection results of the sensor 94 and the sensor 96 and supplies the set screw 14 whose vertical state is appropriate, it is erroneously inappropriate. It is suppressed that a secure set screw is supplied.

  Although the present invention has been described in detail with respect to specific embodiments, the present invention is not limited to such embodiments, and various other embodiments are possible within the scope of the present invention. It is clear to the contractor. For example, although not specifically mentioned in the above embodiment, a vibrator that vibrates the transport pipe 32 may be provided. In this case, clogging of the set screw in the transport pipe is suppressed.
