As shown in figure 12, first sensor 27, second sensor 28,3rd sensor 29, the 4th sensor 46 and the 5th Sensor 47 is electrically connected with controller 6 respectively；Controller 6 respectively with traversing motor 351, stamp motor 382, One reducing motor 21 and second reducing motors 41 are electrically connected with；Controller 6 by baric systerm respectively with gripper cylinder 252, beat Code driving cylinder 39 connects.

Wherein, first sensor 27, second sensor 28,3rd sensor 29, the 4th sensor 46 and the 5th sensor 47 are preferably close to sensor；Traversing motor 351, stamp motor 382 are preferably servomotor；Controller 6 is preferred For PLC.

Wherein, when when feeding position, in order to prevent oscillating platform 24 from driving first reducing motors 21 under gravity Rotate, so that oscillating platform 24 automatically rotates to feeding position when being unable to feeding, first reducing motors 21 are preferably worm gear Worm decelerating machine.

Or the reductor in first reducing motors 21 is any kind, still, the motor of first reducing motors 21 is Motor with brake function, it can also serve the same role.

The device of the application is described in detail with reference to the optimal technical scheme of the application, however, it is necessary to explanation, not Depart from spirit herein in the case of, those skilled in the art can be made on the basis of above disclosure it is any transformation, Modification and variation.The application includes above-mentioned specific embodiment and its any equivalents.
