Next, the operation of the fuse holder supply device configured as described above will be explained. The fuse holder 2 supplied from the parts feeder is supplied to the delivery end 3 while sliding on the sliding rail 4. When the first and second stopper pieces 8 and 9 of the stopper mechanism 5 are raised, the most advanced fuse holder 2 is stopped by the first stopper piece 8. At this time, when the second cylinder 12 of the carrier mechanism 6 is activated, the rotating arm 13 rotates downward, and its tip 14 is attached to the most advanced fuse holder 2.

Next, when the first and second stopper pieces 8 and 9 descend, the first stopper piece 8 is retracted from the most advanced fuse holder 2, and the second fuse holder 2 is moved by the second stopper piece 9. Then stop. Therefore, when the first cylinder 11 of the carrier mechanism 6 is operated, the reciprocating table 10 moves forward, and the fuse holder 2 engaged with the rotating arm 13 is carried out from the parts supply chute 1 and supplied to the clamp mechanism 15. When the fuse holder 2 is interposed between the clamp pieces 18 and 18 in the open state of the clamp mechanism 15, the cylinder 1

Then, the second cylinder 12 of the carrier mechanism 6 is actuated again to raise the pivot arm 13, and then the first cylinder 11 is actuated again to retreat and return to its original position. When the clamp mechanism 15 clamps the fuse holder 2, the first cylinder 21 of the traverser mechanism 16 is actuated to move the clamp mechanism 15 laterally. Then, the fuse holder 2 clamped to the clamp pieces 18, 18 is placed on the first
When facing the receiving portion 29 of the second cylinder 2

Next, when the first and second stopper pieces 8 and 9 of the stopper mechanism 5 rise, the second fuse holder 2 comes off the second stopper piece 9, comes into contact with the first stopper piece 8, and stops. do. Then, as described above, the clamp mechanism 15 is operated by the carrier mechanism 6.
When the clamping mechanism 15 clamps the fuse holder 2, the traverser mechanism 16 operates to move the fuse holder 2 to the second position on the rotating table 24.
It is supplied to the receiving section 30 of. In this case, since the turning table 24 rotates 180 degrees as described above and the second receiving part 30 is located at the position of the first receiving part 29, the stroke of the traverser mechanism 16 is constant, and the stroke of the traverser mechanism 16 is constant. The protruding pieces 2c, 2c of the fuse holders 2, 2 are located on the outside. When the pair of fuse holders 2, 2 are thus set at predetermined positions, the elevating mechanism 31 is activated to raise the revolving table 24 and supply it to the chuck 35 of the assembly robot 34.

Therefore, the fuse holders 2, 2 can be simultaneously supplied to a printed circuit board or the like by an assembly robot.

〔Effect of the invention〕

As explained above, the present invention is capable of automatically clamping the parts supplied from the parts supply chute one by one and supplying them to the turning table, and also making it possible for the turning table to turn and keep the receiving part of the parts constant. In order to position the clamp mechanism, the stroke of the traverser mechanism that moves the clamp mechanism forward and backward can always be kept constant. Therefore, there is no need to make the operating timing of the traverser mechanism variable, and the control device can be simplified.

Further, the component has a pair of support legs and a fitting part formed of a pair of arcuate pieces provided on the upper part of the support legs and into which the ends of the fuse are fitted. While the legs are supported across the sliding chute, the parts are carried out by a carrier mechanism that is inserted and supported in the fitting part, and the parts are further deformed in order to be clamped in a direction perpendicular to the fitting direction of the fitting part. It is possible to reliably supply the parts without any problems, and by simultaneously supplying a pair of parts, it is possible to improve the efficiency of the supply work.
