The second stick 16 is released from the lock and is inherited by the cylinder 30.

The odd-shaped electronic component receiving and transferring mechanism 18 includes a slider 32. The slider 32 has a block shape, and the slider 32 is held by two guide rods 33 in which the slider 32 is loosely inserted, and the two guide rods 33 have one end on the base 13. In addition, it is supported by a bracket 34 that is fixed to the chute cradle 14 side, and the other end is supported by a bracket 35 that is fixed to the end of the base 13 (arm side of the inserter). An actuating rod 36 is projectingly provided on an end surface of the slider 32 on the side of the bracket 34, and a fixed plate 37 and a movable plate 38 are provided in contact with the side surface thereof. Further, the movable plate 38 has a limit switch 39 and a limit switch. A roller 40 is attached. A cylinder 42 having a solenoid valve 41 is mounted on the lower surface side of the base 13, and the operating rod 43 of the cylinder 42 is a portion of the movable plate 38 and the fixed plate 37 which is projected downward by the base 13, and A spring 44, which is interposed between the plates 38 and 37, is provided so that the slider 32 can reciprocate between the brackets 34 and 35 along the two guide rods 33 by the operation of the cylinder 42. ing.

On the side of the slider 32 facing the projecting end surface of the operating rod 36, a table 45 is pivotally supported by its pivoting portion 46 in a vertically rotatable manner (horizontally superimposable on the slider 32). Has been done. More specifically, as shown in FIGS. 9 to 11, the table 45 includes a rectangular block portion 47 having a horizontal lower surface that is horizontally overlapped with the upper surface of the slider 32 and a block on one end side of the block portion 47. The wedge-shaped block has a width of about one-third of the width of the portion 47 and a length of about one-half of the block portion 47, and has an inclined surface 49 on the lower surface and is integrally extended. The rectangular block portion 47 is provided on the upper surface of the rectangular block portion 47 and in the longitudinal direction of the central portion on the wedge block portion 48 side. It has a convex pedestal 50 for receiving one of them and a convex portion 52 via a step portion 51, and the table 45 has its base portion (side portion facing the wedge-shaped block portion 48) as described above. Joint with slider 32 in With a 6 that it is rotatably pivoted.

As shown in FIG. 1, FIG. 8 and FIG. 15, a roller 54 is rotatably supported by the tip of the arm rod 53 fixed horizontally to the upper end of the bracket 34 so that the roller 54 can rotate freely. By the movement of 32, the wedge-shaped block portion 48 is transferred onto the roller 54 via the inclined surface 49, and is inclined at an angle of about 45 degrees which is integral with the chute portion 15. Further, a mechanical valve 55 is arranged on the chute receiving base 14, the wedge-shaped block portion 48 is transferred onto the roller 54 by the movement of the slider 32 and is inclined at about 45 degrees, and the operating rod 36 of the slider 32 is attached to the bracket 34. By inserting the through hole 56 and turning on the mechanical valve 55 at the tip thereof, the operation switching of the two cylinders 29, 30 in the stick accommodating portion 17 is performed in conjunction with this. In FIG. 1, 57 is a substrate having electronic parts such as a timer, 58 is a mechanical valve for manual operation, 59 is a start switch, and 60 is a cover mounting frame. Although not shown in the figure, mechanical valves, cylinders, etc. are connected and connected to each other, and switches, limit switches, patrol lights, etc. are also electrically connected to each other. The electronic component receiving / transferring mechanism 18, the substrate 57, the piping, the wiring, etc. are covered by covers (not shown) on both sides of the mounting frame 60 so that they cannot be seen from the outside.

Next, the operation will be described. In the state where the stick 16 in which a large number of odd-shaped electronic components W are aligned and housed is stacked and housed (for example, 10 pieces) between the pair of holding bodies 24 and 25 (starting switch 59). Is turned on in the automatic mode (automatic operation) (the start switch 59 has two switching modes, the manual mode and the manual mode). Then, the first (lowermost) stick 16 has one end slightly inserted into the hole 27 of the holder 25, and the other end is temporarily locked and held by the cylinder 30. The other end of the second stake 16 is temporarily locked and held by the cylinder 29, and at the same time, the odd-shaped electronic component W in the first (lowermost) stake 16 is passed through the hole 27 of the holder 25 and the chute portion 15 is held. The chutes 20 are slid down and aligned one after another on the pedestal 19 of the chute 20, and the first odd-shaped electronic component W is locked by the stopper cylinder 21 so as not to slide down further. (Second) The odd-shaped electronic component W is temporarily pushed up and locked by the cylinder 23 so as not to be caught by the burr of the chute 20. In this state, the slider 32 and the like are in the original position shown in FIG. Therefore, the limit switch 39 is judged by the switch ON (as shown in FIG. 15, the limit switch 39 is "closed" if there is the variant electronic component W on the table 45). When it is confirmed that the slider is not on the table 45, the solenoid valve 41 and the operating rod 43 of the cylinder 42 are activated through the operation of the timer on the base plate 57, and the slider 32 is shown in FIG. As indicated by the arrow, the slider moves along the guide rod 33 in the direction of the solid arrow b. Then, along with this movement, the rectangular block portion 47 rides on the roller 54 from the inclined surface 49 of the wedge-shaped block portion 48, and the table 45 pivots upward with the pivotal portion 46 as a fulcrum to move the slider 32 (base). The wedge-shaped block portion 48 is integrally joined to the seat 20 in the shoe portion 15 with an inclination angle of θ (approximately 45 degrees) with respect to the base 13), and at the same time, the convex pedestal 50 on the table 45 is seated. When the actuating rod 36 of the slider 32 is inserted through the through hole 56 of the bracket 34 and the switch of the mechanical valve 55 is momentarily turned on at the tip thereof, the stopper is fitted with the convex pedestal 19 of FIG. The cylinder 21 operates to release the locked state, and the first odd-shaped electronic component W slides down by its own weight and is delivered to the pedestal 50 on the table 45. When the stopper cylinder 21 is activated and the locked state of the first part is released, the cylinder 23 is activated and the locked state of the second part is released, and at the same time, the stopper cylinder 21 is originally operated and The third part is locked, and at the same time, the cylinder 23 is actuated to lock the third part. When the first odd-shaped electronic component W is delivered onto the table 45, the timer times out, and the solenoid valve 41 is cut off, as shown in FIG. The slider 32 or the like moves in the direction of the solid arrow a to return to the original position and stop. More specifically, as the actuating rod 43 moves in the direction of the solid arrow a, the wedge-shaped block portion 48 of the table 45 slides off the roller 54 and is transferred onto the slider 32 in a horizontal overlapping state. The presence of the above-mentioned odd-shaped electronic component W is confirmed by the limit switch 39, and the stroke of the operating rod 43 is slightly shortened, and the movable plate 38 is pressed against the elasticity of the spring 44 by the short amount. As a result, the odd-shaped electronic component W on the table 45 is held between the stepped portion 51 and the limit switch roller 40, and the floating is prevented. The odd-shaped electronic component W thus transferred to the original position on the table 45 and mounted in the original position is mounted on the printed circuit board by the insertion machine.

When the odd-shaped electronic component W is supplied to the insertion machine and the odd-shaped electronic component W disappears on the table 45, the slider 32 returns to the receiving position by the judgment of the limit switch 39 again, and the same operation as described above is repeated. . When all the odd-shaped electronic components W in the first stick 16 are delivered, the cylinder 30 is actuated by the signal from the mechanical valve 22 of the cylinder 23 to release the locked state, and the empty first stick 16 becomes the cylinder. The holders 24 and 25 are disengaged from the 30 side and fall outward, and at the same time, the cylinder 29 is actuated to release the locked state of the second stake 16, and the cylinder 30 is transferred again in the locked state. At the same time, the cylinder 29 is actuated and the third stick 16 is locked. In this way, the patrol light 31 is turned on through the operation of the limit switch when the remaining stacked stack 16 remains to be one, and the stack is supplied by the worker.
