Description
Technical field
The present invention relates to a kind of automatic doffing trolleies used in process that doffs of rotor spinning machine.
Background technology
Open-end-spinning, that is, Rotor Spinning Technology is a kind of Advanced Spinning Technologies, usually by being arranged in the more of spinning machine both sides
A individual spinning unit composition.The rotor that the rove of single fiber shape can be processed as twisted yarn by each spinning unit by one
It is constituted with the winder unit of guiding yarn winding to one tube of a spool up stroke.On a revolving cup spinning production line, lead to
Often there are multiple spinning spindle positions, one to two automatic doffing trolley is commonly provided in every one side of this rotor spinning machine.Work as bobbin
When reaching preset length of yarn or bobbin diameter, the lick-up on automatic rotor spinning machine is changed pipe and is activated.Essence
True electronic length detection device makes in the deviation range that the difference of length of yarn between bobbin and bobbin is maintained at a very little.
And mechanical parking is then less accurate when bobbin diameter reaches certain value, because the winding condition on different spinning spindle positions is not
Together, such as yarn Zhang Butong, there is the case where skidding in spindle, bobbin diameter and yarn winding length just will produce difference.
The major function realized required for doffing cart is will to wind the bobbin completed to release, and changes new spool, continues
Spinning process.One complete process of doffing is made of multiple and different operating process, including：Doffing cart gas port access behaviour
Make, inhale yarn operation, bobbin cradle lifts operation, bobbin cradle opening operation, bobbin cradle pressing operation, bobbin release operation, yarn sent to grasp
Make, group yarn operation, spool captures and release operation, different operating process are realized by different devices.
The mode of doffing of rotor spinning machine is broadly divided into two kinds, respectively manually doffs and automatic doffing.For longer
For production line, the labor intensity that manually doffs is larger, less efficient.Automatic doffing vehicle structure used at present is complicated, from
Dynamicization degree is relatively low, and the time of doffing is longer.It during doffing, needs to realize doffing operation by hand fit, influences production effect
Rate.
