Description
Technical field
The present invention relates to draw drawing-in machine and the corresponding method of drawing organizine of the organizine of a warp thread in the part of a frame of textile machine.
Background technology
A kind of like this drawing-in machine or pull-in method for example are known in US3681825, EP0446326 and EP0460129.
In order to draw a kind of organizine of warp thread in the part of a frame of textile machine, 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 as far as possible simply described separation, at first arrange organizine to such an extent that make it (preferably in an aspect and the organizine that arranges abreast each other) and consist of one (warp) silk layer.
In order to isolate single organizine from described silk layer, mostly described silk layer is tightened and stretched on a reel that is positioned between two card articles (a upper card article and a lower card article).In order separating by means of a separator are, the top organizine in described silk layer edge to be opened from the deflection of described layer, then to be held by a silk clip and then this organizine of cutting below card article on described.Be stretched in the scope of a length section between these two card articles at it in next step the organizine that has separated is taken out from described organizine layer, make in the lower end, that is to say above described lower card article, utilize one to draw utensil, drag hook for example grasps the organizine that has separated.Thereby following the described utensil that connects draws back the corresponding organizine that is grasping and draws this organizine thereupon and at last this organizine 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 drawing-in machine is that described clamping force is merely able to change when replacing from a warp thread to another warp thread.If inner use of same warp thread, the organizine of different qualities is being arranged aspect its coefficient of friction, just be necessary for and regulate described clamping force-set about-attempt a kind of optimization from empirical value, select in other words one compromise or in the situation that the described pulling rate degree of certain coupling, with the different qualities of all organizine of considering this warp thread, and for example prevent due to Si Ka and/or draw the single organizine of effect damage of utensil.The standby drawing-in machine of repacking or find out clamping force and a suitable optimization of pulling rate degree is usually that height expends is 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.In the situation that using organizine by different material behaviors to form, warp thread also reduces operational efficiency (estimating the organizine number that draws for the unit interval).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 be determined by those organizine responsive especially and that therefore have to draw with minimum pulling rate degree in fact, all organizine of especially same warp thread can only and be merely able to same clamping force clamping draw with same pulling rate degree.
Summary of the invention
Therefore basic task of the present invention is, avoids above-mentioned shortcoming, and creates a kind of drawing-in machine that draws the organizine of a warp thread in the part of a frame of textile machine, and described drawing-in machine can high-quality, process expeditiously the organizine that the material by different speciality consists of.Should determine in addition a kind of corresponding method of drawing organizine.
Described task is completed by following a kind of drawing-in machine and a kind of method of warp thread of drawing.
Draw the drawing-in machine of the organizine of a warp thread to comprise a silk card that is used for one of described organizine of clamping, one for the part to a frame of textile machine to be used for drawing correspondingly draw utensil and one of the organizine held by described silk clip to be used for controlling described silk card and/or the described control device that draws utensil to one of part of described frame of textile machine according to of the present invention.
