Description
Technical field
The invention belongs to textile machine manufacturing technology field, it is related to the improvement of doffing trolley on bobbin-winding machine, specifically one
The spinning-in system and threading method of kind doffing trolley.
Background technology
Doffing trolley is equipped with a kind of doffing equipment on automatic winder, is thin network connection automatic winder and large yarn library
Indispensable configuration on type automatic winder.Doffing trolley replaces artificial doffing with automatic equipment, manually puts cylinder, improves on the whole
The level of automatic winder automation.The purpose is to mitigate the labor intensity of spinner, doffing automation is realized.
When single ingot sends out full cylinder signal, i.e., cylinder yarn reaches length or weight setpoint value, the cylinder yarn that doffing trolley expires network
It is removed from support arm, ready bare bobbin is put on support arm, and coil yarn is captured from specified position, by what is grabbed
Coil yarn, which is wound into, newly changes the designated position on bare bobbin, needs yarn fixing device to receive yarn during yarn movement
Collect and be fixed on required position, so that loose thread to be smoothly fixed between support arm big end and bare bobbin, and twines as required
On bare bobbin.
In existing doffing trolley, the yarn grabbing mechanism of spinning-in system first is controlled by cam completely, convex after completing yarn grabbing
Wheel has been rotated through certain angle, due to the irreversibility of cam rotation herein, once yarn grabbing mechanism yarn grabbing fails, Jiu Huizao
Fail at entire doffing.
How a kind of spinning-in system and method for doffing trolley are provided so that after a yarn grabbing failure, single ingot can be again
Splice one or many until yarn grabbing success.This is current the art urgent problem to be solved.
Invention content
The present invention is in order to solve the problems existing in the prior art and insufficient, provides a kind of spinning-in system and repiece of doffing trolley
Method so that after a yarn grabbing failure, single ingot can splice again one or many until yarn grabbing success, improves doffing trolley
Doffing success rate.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of spinning-in system of doffing trolley, including the yarn grasping mechanism of doffing trolley, groove drum, groove drum shield yarn plate, yarn clearer,
Thread board and control system, the yarn grasping mechanism include that yarn grabbing cylinder, yarn grabbing cam and yarn grabbing scissors, feature exist
In the yarn grasping mechanism further includes yarn grabbing cylinder pushing mechanism, and it is small that the yarn grabbing cylinder pushing mechanism is fixed on doffing
Che Shang, for the yarn grabbing cylinder pushing mechanism for pushing the telescopic arm of the yarn grabbing cylinder to move, the yarn grabbing cylinder pushes machine
The driving portion of structure pushes the telescopic arm of the yarn grabbing cylinder to move by control system control, and yarn is made to be cut into the yarn grabbing
In the edge of a knife of knife.
Improvement to above-mentioned technical proposal：The telescopic arm is formed by a section telescoping tube and a section telescopic bar grafting, institute
It states and the yarn grabbing scissors, when the yarn grabbing cylinder pushing mechanism drives, the yarn grabbing cylinder is set on one end of telescopic rod
It is contacted in the middle part of the driving portion of pushing mechanism and the telescoping tube.
Above-mentioned technical proposal is further improved：The yarn grabbing cylinder pushing mechanism is driving cylinder, the driving gas
It is contacted in the middle part of the driving telescopic rod of cylinder and the telescoping tube.
Above-mentioned technical proposal is further improved：The yarn grabbing cylinder pushing mechanism is push-pull electromagnet, described
The main body of push-pull electromagnet is arranged on the doffing trolley, magnetic core push rod and the telescoping tube of the push-pull electromagnet
Middle part contacts.
Above-mentioned technical proposal is further improved：The yarn grabbing cylinder pushing mechanism is linear motor, the straight line
It is contacted in the middle part of the driving portion of motor and the telescoping tube.
It is a kind of to utilize a kind of above-mentioned threading method of the spinning-in system of doffing trolley, which is characterized in that the threading method
Include the following steps：
（1）Cylinder yarn stops after expiring cylinder, and cutting continuous strand, the telescopic arm that control system controls yarn grabbing cylinder are not extended yarn yarn clearer
Grasping mechanism is sent to from home position above the thread board of yarn clearer, and stretching for yarn grabbing cylinder is pushed by yarn grabbing cylinder pushing mechanism
Contracting arm moves, and yarn is made to import in the edge of a knife of yarn grabbing scissors；
（2）After yarn grabbing scissors cuts the yarn on top and clamps the yarn of lower part, yarn is clamped in yarn grabbing cylinder pushing mechanism return
Line is pushed outwardly, and yarn grabbing scissors is collided with groove drum shield yarn plate when avoiding rising, and the telescopic arm that control system controls yarn grabbing cylinder returns
Contracting rises to initial position；
（3）Yarn clearer is detected yarn, if there is yarn means that yarn grabbing success；If yarn clearer does not detect yarn
Line, then it represents that yarn grabbing fails；
（4）If yarn grabbing fails, because yarn grabbing cam does not rotate at this time, doffing trolley is beaten again still in original state, single ingot
Knot is primary, presses the step (1)-again（3）Process carry out yarn grabbing, until yarn grabbing success, finally complete entire doffing process.
The present invention compared with prior art the advantages of and good effect be：
1, the present invention increases by a yarn grabbing cylinder pushing mechanism, yarn grabbing cylinder pushing mechanism is used for by improving yarn grasping mechanism
The telescopic arm of the yarn grabbing cylinder is pushed to move, when the yarn grabbing cylinder pushing mechanism drives, yarn grabbing cylinder pushing mechanism
Driving portion and flexible arm contact, and controlled by control system and the telescopic arm of yarn grabbing cylinder is pushed to move, make to grab described in yarn entrance
In the edge of a knife of yarn scissors.In this way so that after yarn grabbing failure, because yarn grabbing cam does not rotate at this time, doffing trolley is still in first
Beginning state, single ingot knot once again, and single ingot can splice again one or many until yarn grabbing success, substantially increases doffing
Trolley doffing success rate；
2, yarn grasping mechanism of the invention is simple in structure, and processing and fabricating is convenient, and cost is relatively low.
