Generally, in order to send a work such as a semiconductor device to another process through one process, a turntable for continuously carrying the work from a predetermined position to a predetermined position is commonly used. In this type of turntable, when multiple workpieces that have been supplied to the same station at the supply position and handled are taken out from one place to one place at the take-out position, conventionally there are multiple workpieces at each station of the turntable. A turntable is provided by providing a head having holding means movable in the normal direction of the turntable, and intermittently shifting a plurality of holding means of the head by utilizing the linear reciprocating motion of a linear reciprocating mechanism such as a cylinder. A plurality of works handled at the same station are taken out from one place.

For example, when a semiconductor element cut from a warped lead frame that has undergone pellet mounting, wire bonding, and resin molding processes is delivered to the lead forming process, high speed is required. However, in the intermittent shift of the head performed by utilizing the linear reciprocating motion of the conventional linear reciprocating mechanism such as a cylinder, it takes time for the plurality of holding means of the head to return to the original position before the shift. Then, there was a problem that high-speed delivery was not possible.

First, the turntable (1) intermittently rotates in the direction of the arrow shown in FIG. 1 , and a plurality of work pieces, that is, two work pieces are supplied to the head (3) that is temporarily stopped at the supply position (P 1 ). The holding means (5) and (6) handle them respectively. Then, the turntable (1) is intermittently rotated again and the holding means (5) (6) together with the turntable (1).
When the head (3) that is handling the workpieces respectively is rotated to an intermediate position between the supply position (P 1 ) and the take-out position (P 2 ), the cam follower (7) of the head (3) moves to the fixed cam (10). ) Abuts on the starting end of the cam surface (11). Next, when the turntable (1) is intermittently rotated again, the head (3) is rotated together with the turntable (1), and along with this rotation, the cam surface (11) of the fixed cam (10).
The head (3) moves inward in the normal direction against the tension spring (8) via the cam follower (7) that abuts against the. Then, when the head (3) is rotated by the take-out positioner (P 2 ), the head (3) is moved radially inward by the distance (H) between the work holding means (5) and (6), and The cam follower (7) transfers from the end of the cam surface (11) of the fixed cam (10) to the threaded cam surface (13) of the barrel cam (12) and contacts the spiral cam surface (13) of the barrel cam (12). Here, the workpieces handled by the workpiece holding means (5) and (6) are taken out from one place while the head (3) is temporarily stopped. That is, when the head (3) is rotated to the take-out position (P 2 ), first, the work handled by the one (outer) work holding means (5) is taken out, and then the barrel cam (12) is moved to 1 When rotated, the head (3) holds the workpiece outward in the normal direction by the tension spring (8) via the cam follower (7) that comes into contact with the spiral cam surface (13) of the barrel cam (12) as shown in FIG. After moving the distance (H) between the means (5) and (6), the work handled by the inner work holding mechanism (6) is taken out, and two works are taken out from one place. The transfer section (2) from which the work has been taken out is rotated to the supply position (P 1 ) again with the intermittent rotation of the turntable (1), and thereafter the same operation is repeated.
