7 is disposed, and a rotating shaft 19 is rotatably inserted into the sliding tube 17 by means of a bearing 18.
The middle of the swing mounting plate 20 is attached to the front outer peripheral surface of the sliding tube 1.
7, a driving wheel 21 is fixed to the front part of the rotating shaft 19, and a folding ring 22 and a forming ring 23 are protruded from one part of the swinging mounting plate 20 with a predetermined gap. , a rotating belt 24 is wound around the driving wheel 21 and the folding wheel 22, and a swinging cylinder 2 is attached to the mounting body 14.
5 upright, and its cylinder rod is attached to the swinging mounting plate 2.
0 through a pin 26.

Further, 27 is a vibration mechanism, which is attached to the mounting body 1.
4 is provided with a vibration motor 28, an eccentric roller 29 is fixed to its main shaft, and the eccentric roller 29 is engaged with the concave ring groove 30 on the outer circumferential surface of the sliding tube 17, so that the vibration motor 28 rotates. Therefore, due to the eccentric action, the sliding tube 17,
Rotating shaft 19, swing mounting plate 20, rotating belt 24
etc. can be freely slid back and forth.

Further, the rotation shaft 19 is rotated via a belt 31 and a pulley 32 by a rotation motor (not shown).

Further, a sliding rod 34 is horizontally installed by a bearing 33 below the rotating shaft 19 so as to be freely slidable, an engaging piece 35 is attached to the rear part of the sliding rod 34, and the engaging piece 35 is inserted into the concave annular groove 30. A mounting arm 36 is provided protruding from the front part of the sliding rod 34, and the mounting arm 36 has two
