Description
Technical field
The invention belongs to RING SPINNING to doff equipment technical field, in particular to a kind of structure design revolving ingot pine RING SPINNING automatic doffer in advance.
Background technology
Ring spinning is a kind of extremely important and general spinning technique. In the process of ring spun yarn, it is necessary to being taken off from the spindle of spinning frame by the spool (being called full spool or cop) having spun yarn, this link is called doffs. The mode of doffing of current ring spinning frame is divided into two big classes, a class be manually doff spool is chosen from ingot bar with hand by people after put into yarn basket, and the empty spool not having yarn is put on ingot bar; Another class is that machine doffs, come one by one with doffer or short run take off spool, adopting Intubaction device to be put into by empty spool on ingot bar, some spinning frames carry integral cosine doffing device simultaneously, utilize its collective doffing mechanism to doff in large quantity and intubate work simultaneously.
Spool is needed to fit tightly ingot bar during Spinning Frame spun yarn, the rotating speed of spool and ingot bar could be allowed like this to be consistent, the main CD-ROM drive motor high-speed rotation (be generally several thousand turns every minute, even up to ten thousand turns) of spinning frame followed by ingot bar under the transmission of transmission belt. Spinning frame is divided into two big classes, and a class adopts light ingot bar, and a class adopts aluminium loop bar. Aluminium loop bar is owing to there being spring centrifugal globe device can reach spool and the fitting tightly of ingot bar when ingot bar rotates, and when ingot bar does not turn, less being convenient to of frictional force between spool and ingot bar takes off, and therefore, all adopts aluminium loop bar with the spinning frame of integral cosine doffing device. But the device of aluminium loop bar is complicated, and cost is higher, the spinning frame existing market occupancy volume with collective doffing is less.
Most spinning frames adopt the light ingot bar of low cost; but there is the difficult problem pulling out yarn difficulty in light ingot bar: in order to ensure spool and effective laminating of light ingot bar; the interior hole of the spool interior hole of cylinder (namely in spool) has certain Small Taper; the tapering of itself and light ingot bar coincide and better forms closely cooperating of the self-locking conical surface; spinning effect is better; but; part spool Chang Huiyu ingot bar was fitted tight and was produced the sealing area of local lower than normal atmosphere, caused normal atmosphere to hinder choosing for spool. Especially more easily there is such problem in the spool of life-time service, and when the wadding sealing of the dirt of life-time service and spinning, high speed rotating agrees with, and these combined factors cause in spool the airtight phenomenon in local between cylinder and ingot bar. Therefore, the yarn success ratio of pulling out of doffer affects seriously by this, runs into the spool not pulled out to get off and causes shutting down and cannot running well, the phenomenon of breaking-up equipment even occurs.
A kind of Doffing manipulator device (Chinese utility model patent CN2466174Y), comprises pipeline mechanism, intubation mechanism, Bo Sha mechanism, shear mechanism and motor etc. The method of work of this device is: have different rises angle pre-loose dish and lifting dish clamp the yarn position of full spool. When doffing cart advances, spool produces axis component and radial component. Axis component plays pre-pine and pulls up full spool functional requirement, completes automatic doffing work. Its weak point is: owing to the wedge of full spool and ingot bar is made a concerted effort relatively big, therefore the radial component being applied on full spool is greater than the radial component being applied on full spool when manually doffing, and can affect the precision of spindle bearing. Owing to clamping the yarn position of full spool, can destroy by the quality parameter of retaining part yarn.
A kind of spinning frame automatic doffing dolly (Chinese invention patent CN103255514B), comprises doffing cart and automatic doffer. it is positioned at base plate above doffing cart and it is provided with automatic doffer, the Yu Song mechanism of this doffer is arranged on the base plate of doffing cart by Steel Spring Plate, Steel Spring Plate is fixed with pre-pine block, when dolly advances, pre-pine block advances with dolly, the insertion lower end of full spool, make full spool lower end edge in advance pine block inclined-plane on rise, then pre-pine block is under the effect of plane cam, withstand the lower end of full spool, upwards move along the direction parallel with ingot rod axis, under ingot hook barrier effect, full spool and ingot bar are departed from, the full spool popped up enters in robot device, the upper end of mechanical paw is clamped in the position of full spool upper end without yarn, and then full spool is extracted. its weak point is: 1) process the existence of error and the difference of the degree of wear due to spool, there is very big fluctuation hundreds of full spools position in the height direction for rail reference plane, height is not neat, it is difficult to uniform, therefore pre-pine block is made can not to stablize the contact lower end of full spool, causing pre-pine effect fluctuation very big, what have does not simply reach pre-pine object, 2) owing to the bonding force between full spool and ingot bar is bigger, this kind adopts the pre-pine block mode that upwards jack-up full spool realizes pre-pine to need very big strength, and energy consumption is higher, and bigger reactive force occurs simultaneously, produce vibration and noise, affect doffer resistance to overturning, 3) this kind of mode needs the plate cam installing total length tens meters on spinning frame, and cost height, installation is wasted time and energy.
