  When the rotary drum 1 is stopped in a state where the entrance / exit 14 is at the top and the bowl-shaped container 21 is positioned below, the entire amount of the work is stored in the bowl-shaped container 21, and the workpiece storage mechanism 2 is moved backward to move the rotary drum 1. If the bowl-shaped container 21 is extracted from the inner peripheral cylinder 4 and the work taken out from the bowl-shaped container 21 is placed on the carriage 32 and carried out, the work of the work is completed.

  Thus, when the workpiece is taken out, the kelen member and the workpiece are separated, and only the kelen member remains on the rotating drum 1 side, and the workpiece is taken out while the bowl-shaped container 21 is taken out from the rotating drum 1. The operator does not need to put a part of the body into the rotary drum 1 during the work picking work, and the work picking work can be improved in safety and efficiency.

  Next, a second embodiment shown in FIGS. 9 to 12 will be described.

An annular end plate 41a is provided around the end portion on the opening side to prevent the swell member from spilling out.

  The work rotating mechanism 42 is disposed at the open end of the rotating drum 41 so that a cart 51 that moves toward and away from the rotating drum 41 is driven by a motor along the rail 52. A bearing 53 provided on the upper side rotatably supports a work mounting shaft 54 arranged substantially coaxially with the rotary drum 41, and a lid that closes the opening of the rotary drum 41 at the end of the rotary shaft 54 on the side of the carriage 51. A member 55 is provided, and the rotating shaft 54 and the lid member 55 are integrally rotated with the rotating drum 41 in the same direction or in the reverse direction by driving by a motor on the carriage 51.

If the rotary shaft 54 on which the workpiece A is mounted is extracted from the rotary drum 41, and the workpiece A removed from the rotary shaft 54 is placed on a carriage or the like and carried out, the work of the workpiece is completed.

  When the rotating drum 41 is stopped, only the workpiece rotating mechanism 42 may be rotated to separate the keren member from the workpiece by centrifugal force, so that the kelen member and the workpiece can be more reliably separated.

  Also in the second embodiment, as in the first embodiment, the kelen member and the work are separated when the workpiece is taken out, and only the kelen member remains on the rotary drum 41 side, and the workpiece is taken out from the rotary drum 41. Therefore, the operator does not need to put a part of the body into the rotating drum 41 during the work picking work, and the work picking work can be improved in safety and efficiency.

  In addition to the structure shown in the figure, the work rotation mechanism 42 in the second embodiment has an outer diameter that fits in the rotary drum 41 with a margin, and has a mesh smaller than the work and larger than the keren member. Then, it is possible to employ a structure in which a wire mesh cylinder that accommodates a work in an insertable manner is rotatably attached to the carriage 51, and a kelen member is caused to collide with the work in the cylinder to perform keren.
