Description

Device and method for removing tail yarn on cop

Technical Field

The invention belongs to the technical field of textile machinery manufacturing, relates to improvement of a tray type bobbin winder, and particularly relates to a device and a method for removing tail yarns on cops.

Background

The bobbin yarn that the spinning frame falls always leaves longer tail yarn, and when bobbin yarn is spooled on the tray type winder, the tail yarn is easy to be entangled with yarn heads, so that the yarn ends of the bobbin yarn are seriously influenced, and even if the bobbin yarn with successful yarn ends is unwound to the bottom, the yarn in unwinding can interfere with the tail yarn, so that the unwinding tension of the yarn is rapidly increased, the yarn ends are caused, and the production efficiency of the winder is seriously influenced.

At present, a tray type bobbin winder is provided with a tail yarn removing device, wherein the tail yarn removing device comprises a box body with a negative pressure air inlet, a thorn stick and a driving mechanism. Cop is inserted on the tray through the intubate mechanism, and then is sent to the waiting station before the pick in the drawing through the tray conveyor, and the cop usually contains wrapping yarn and tail yarn. After the cop reaches the pick-up station, the cop rotates under the drive of the tray, the tail yarn of the cop is removed through the tail yarn removing device, and the tail yarn is sucked into the box body through the negative pressure air inlet under the action of negative pressure. There are two current methods of removing the yarn after it reaches the inside of the box, the first method is to break with a single spike and the second method is to cut with rotary scissors. The first method has the problem that the yarn end reaches the inside of the box in general in two states: one end of the yarn is held by the cop, and the other end is broken at high speed by a thorn rod and sucked away through a negative pressure air outlet; the second state is that the yarn tail is broken from the cop when being sucked in and loses the effect of holding, and the yarn will twine on the thorn rod under this state to can twine more, lose the effect of thorn rod at last, often need the manual cleaning yarn of twining on the thorn rod. The second method has the problems that the rotary scissors must rotate at high speed, the service life of the scissors is short, the cost is high, and the structure is complex. Therefore, the prior art has defects when solving tail yarns on cops, so that the success rate of the head generation is low, and the production efficiency of single ingots is low.
