The upper canister portion 311 of turnbarrel 31 is driven to rotate by driving motor, the upper canister portion 311 drives planetary gear
313 rotations, planetary gear 313 drives lower canister portion 312 to rotate, therefore can make the direction of rotation of canister portion 311 and lower canister portion 312
On the contrary, and rotating speed it is identical；In rotation process, since upper canister portion 311 and the height and position of lower canister portion 312 are constant, first
Guide pad 315 is rotated on the second guide pad 316 comfortable horizontal plane each always, and height does not also change.
As shown in fig. 7, when in the first station, first guide pad 315 is located at the initiating terminal of the first guide groove
When 321a, second guide pad 316 is located at the initiating terminal 322a of second guide groove；Canister portion 311 turns in upper canister portion 311
It is dynamic that the first guide pad 315 is driven to be moved in the first guide groove 321 so that it moves back and forth column 32 and moves down, this canister portion at present
312 rotate backward, and drive the second guide pad 316 to rotate backward, to turn to second station, as shown in Figure 8；When the first guiding
When block 315 turns to the clearing end of the first guide groove 321, as shown in figure 9, being 3rd station, just the second guide pad 316 at this time
The clearing end of the second guide groove 322 is turned to, and moves back and forth column 32 and drops to minimum point；With being rotated further, first leads
It is detached from the first guide groove 321 to block 315, and the second guide pad 316 enters the second guide groove 322 and along the second guide groove 322
It is mobile, it is begun to ramp up so that moving back and forth column 32, is at this time the 4th station as shown in Figure 10；Until the second guide pad 316
The initiating terminal 322a of the second guide groove is turned to, column 32 is moved back and forth at this time and rises to peak, return to the first station at this time, and
And repetitive operation.
In whole process, the first guide pad 315 and 316 alternating action of the second guide pad, can in moving back and forth on column 32
316 service life of the first guide pad 315 and the second guide pad is effectively improved, and the two rotation direction is on the contrary, compared to only setting
Setting keeps the stress of reciprocating movement column 32 more balanced for a guide pad, and operation is more stablized.
