In the scallop drilling machine, which comprises a pressing device that presses the scallop downwards, the low end opening edge of the opposite side walls of the scallop self-propelled groove chute is located on the guide member disposition side of the starting end of the thread. To the top of both adjacent threads of the screw thread, and to allow passage of a scallop that has fallen into the valley of the screw at the low end of the side wall located on the side of the lead of the screw thread of the chute. And a cross section of the chute above the lower end of the chute, and at least two parallel striations with a distance larger than the diameter of the scallop. A rod is arranged, and the stopper rods are moved up and down between a position where the feed screw is stopped or just before the stop of the scallop to allow passage of the scallop and a position where the sliding of the subsequent scallop is stopped after the passage of the scallop. The operating device is provided, and further, an engaging portion into which the corner of the ear-like protrusion of the scallop fits is provided in front of the lower end of the bottom wall of the chute.

[Action]

Supply the scallops that were manually grasped into the high end of the chute so that the ears are on the lower side.

The supplied scallop slides in the chute and stops when it contacts the upper stopper rod that is stopped at the descending position.

Each stopper rod allows the passage of the scallop that has risen and stopped due to the action of the feed screw of the operating device or the action immediately before the stop, and since it descends to the original position after the passage of the scallop, it passes under the upper stopper rod. The scallop that was made stops due to the lower stopper rod.

The scallops sequentially supplied by repeating the above process are stopped by the respective stopper rods, and the scallops are dropped to the feed starting end side of the valley of the feed screw which is stopped as the lower stopper rods are raised.
