Description
Technical field
The present invention relates in the part of a frame of textile machine, to draw the machine drawing and the corresponding method of drawing organizine of the organizine of a warp thread.
Background technology
A kind of like this machine drawing or pull-in method for example are known in US3681825, EP0446326 and EP0460129.
In order in the part of a frame of textile machine, to draw a kind of organizine of warp thread, usually organizine is individually isolated from warp thread and the corresponding organizine that has separated is individually drawn in attaching troops to a unit in that part of this corresponding organizine of a frame of textile machine.In order enough machines to carry out described separation as far as possible simply, at first arrange organizine to such an extent that make it (preferably in an aspect and the organizine of arranging abreast each other) and constitute one (warp) silk layer.
In order to isolate single organizine, mostly described silk layer is tightened and stretched on a reel that is positioned between two card articles (going up card article and a following card article for) from described silk layer.In order separating the top organizine in described silk layer edge to be opened from the deflection of described layer, to be held by a silk clip then and then this organizine of cutting below the card article on described by means of a separation utensil.In next procedure, be stretched in the scope of a length section between these two card articles the organizine that has separated is taken out from described organizine layer at it, make in the lower end, that is to say above described card article down, utilize one to draw utensil, the organizine that drag hook for example, grasping have separated.Thereby follow and describedly connect organizine that utensil corresponding grasping and draw back and draw this organizine thereupon and at last this organizine is fully extracted from described silk card.
The clamping force of described silk card is looked the characteristic of organizine and different.Similarly, if change pulling rate degree (in other words, described speed of drawing utensil motion itself when drawing), the clamping force of requirement also can change.For a kind of optimization can be arranged, the clamping force of described silk card is adjustable.
The shortcoming of known machine drawing is that described clamping force is merely able to changing when another warp thread replaces from a warp thread.If use at the organizine that different qualities is arranged aspect its coefficient of friction in same warp thread inside, just be necessary for and regulate described clamping force-set about-attempt a kind of optimization from empirical value, select one to trade off or the described pulling rate degree of coupling under certain situation in other words, with the different qualities of all organizine of considering this warp thread, and for example prevent because Si Ka and/or draw the single organizine of effect damage of utensil.Repacking is equipped with a machine drawing or finds out clamping force and a suitable optimization of pulling rate degree usually is that height expends, especially when usually processing the organizine made from different materials.In order to change the clamping force of silk card, generally need the manual of operating personnel to get involved.Use at warp thread and also to reduce operational efficiency (estimating the organizine number that draws for the unit interval) under the situation about forming by the organizine of different material behaviors.For example corresponding clamping force or pulling rate degree must not surpass certain predetermined threshold when considering responsive especially organizine.Draw the needed time of all organizine of a warp thread therefore to determine that by those organizine responsive especially and that therefore have to draw all organizine of especially same warp thread can only and be merely able to same clamping force clamping draw with same pulling rate degree in fact with minimum pulling rate degree.
Summary of the invention
Therefore basic task of the present invention is, avoids above-mentioned shortcoming, and creates a kind of machine drawing of drawing the organizine of a warp thread in the part of a frame of textile machine, and described machine drawing can high-quality, process the organizine that the material by different speciality constitutes expeditiously.Should determine a kind of corresponding method of drawing organizine in addition.
Described task is finished by following a kind of machine drawing and a kind of method of warp thread of drawing.
The part that is used for to a frame of textile machine according to the present invention draws the machine drawing of the organizine of a warp thread to comprise a silk card that is used for one of described organizine of clamping, one to be used for drawing correspondingly draw utensil and one of the organizine held by described silk clip to be used to control described silk card and/or the described control device that draws utensil to one of part of described frame of textile machine.
Comprise a measurement mechanism that is used to survey at least one yarn silk parameter of corresponding organizine according to machine drawing of the present invention, wherein can depend on described silk card of yarn silk parameter control and/or the described utensil that draws that at least one is correspondingly surveyed by described measurement mechanism.
Reach thus, can be before drawing according to the individual characteristic that its other characteristic aspect is determined the characteristic of each organizine and described control device can be considered single organizine in real time when the process that control is drawn.In this way can, when the single organizine of processing according to the described machine drawing of its characteristic optimizing ground adjusting.Can pass through the organizine of different yarn silk parameter identification different qualities, thereby no longer need the manual adjustment of clamping force.Obviously, in the time will being processed with the organizine of different material behaviors, be particularly advantageous, for example when processing after one first warp thread of processing when with the organizine of first warp thread other another warp thread being arranged aspect at least one yarn silk parameter, perhaps a kind of own during by a series of warp thread of forming by the organizine of different yarn silk parameters when processing.
The implementation of looking described measurement mechanism is and different, and the yarn silk parameter of being surveyed by corresponding measurement mechanism can be different.
