Technical field
The present invention relates to a kind of inserting tube yarn spindle.The inserting tube yarn spindle that particularly relates to a kind of cross winding automatic device working position, it has and the fixing device of giving the mating reaction of yarn bobbin spool, and it is installed in the housing.
Background technology
Recently, cross winding automatic device with a plurality of control positioies is disclosed with different embodiments, on inserting tube yarn spindle fixing give yarn bobbin again around (umspulen) (or rewinding) become through remove the defect yarn and/or roll up winding bobbin greatly, preferred form is a cross winding bobbin.
For example, DE 10040106A1 discloses a kind of cross winding automatic device, provides new for yarn bobbin through special machine cop and spool delivery system to its control position.These are arranged on the transfer dish for yarn bobbin (or cop), and transfer dish has is locating the inserting tube yarn spindle of giving yarn bobbin in the back-haul preface again.
Also have a kind of disclosed cross winding automatic device, it has respectively in each work area and is used for one or more cop storehouses that particular job is regulated of carrying out of giving yarn bobbin.
For example, EP 0970910A1 has described a kind of cross winding automatic device, and it has cross winding respectively and handles feedway in the control position zone.Handle feedway by cross winding and supply unit can be transformed into the unwinding position from the position of getting the raw materials ready, wherein on the inserting tube yarn spindle of its supply unit, be provided for respectively again around unwinding cheese.
DE 19816188A1 has described a kind of cross winding automatic device, and its control position is installed circular cop storehouse.This known loom also has except deposit is given the circular cop storehouse of yarn bobbin in the work area and will be transferred to the cop slideway of unwinding position to yarn bobbin and walk around the inserting tube yarn spindle of locating in the journey to yarn bobbin again.For this loom, for again around, be transported at first the accepting the inserting tube yarn spindle of location positioning on of swinging mounting from the circular cop storehouse of rotating support through the cop slideway to yarn bobbin, its inserting tube yarn spindle is with putting control position to yarn bobbin after accepting to give yarn bobbin, at this control position, be in to the big volume cross winding bobbin of the reel for yarn coiled on the yarn bobbin.Yarn through the check of defect yarn feeding device, is removed simultaneously simultaneously.
The inserting tube yarn spindle of known cross winding automatic device is made of 2 holders as described at CH-PS 396718 usually.Be clamped in promptly that inserting tube yarn spindle in the spool of unwinding cheese has hard contact surface and with respect to the clamping lever of its contact surface swinging mounting, it is positioned at unwinding cheese on the inserting tube yarn spindle when supporting.At the clip position of inserting tube yarn spindle, its contact surface and clamping lever are resisted against on the inwall of spool.
By the inserting tube yarn spindle of this known and 2 holder effects, can not guarantee enough accurately and the same unwinding of oriented phase, as needed for the cross winding automatic device of present high speed yarn unwinding.
Also disclose transfer dish relatively for the relevant cross winding automatic device of yarn bobbin spool delivery system with having special machine, it is equipped with inserting tube yarn spindle.Be that known transfer dish has center shaft, integrated thereon specific clamp assembly.For example in the transfer dish of in DE 4227302A1, describing, the chuck of integrated differing heights on center shaft.Chuck forms two chuck groups, and they are resisted against on the yarn bobbin from interior by spring-loaded independently of one another, thus, accurately locatees for yarn bobbin in vertical direction.
But the shortcoming of this known transfer dish is, because the balance staff of chuck is arranged on the inside of center shaft, the useful clamping path of seriously having limited inserting tube yarn spindle.In fact this caused its transfer dish only to be fit to the spool of specific dimensions, and when the spool change in size, need to change transfer dish usually.The inside that the chuck balance staff is arranged on the transfer dish center shaft also can cause disadvantageous lever transmission ratio also to have a strong impact on the gripping power of transfer dish clamp assembly thus.That is to say that the known transfer dish center shaft in-to-in clamp assembly that is arranged on is not suitable for such inserting tube yarn spindle, promptly this inserting tube yarn spindle accurately clamps the spool of different size, particularly under the repacking work of not taking a lot of trouble.
Summary of the invention
According to above-mentioned prior art, the objective of the invention is to improve the inserting tube yarn spindle of cross winding automatic device working position, guarantee the spool of giving the accurate orientation of yarn bobbin in the journey and guaranteeing to locate different size walking around again with enough big gripping power.
