Abstract

A device for tensioning warp threads on a drawer-in for warp threads has a substantially vertical frame (1) for tensioned warp threads arranged next to a warp thread cutting device (13) arranged in a marginal region of the frame. In order to provide a simple and light device of said type, in which the warp threads to be cut and the warp thread cutting device are positioned as precisely as possible relative to each other, the frame is movably mounted in a marginal region (16) and is guided by a fixed roller (19) so as to move in the direction of the main axis (22) and in a direction perpendicular thereto. In another marginal region (12), the frame is directly linked to the thread cutting device so as to move in the same direction as the latter.

Description

Warp thread is added to device on the drawing-in machine

Characteristic according to independent claims 1, the present invention relates to a kind of being used for warp thread is added to device on the drawing-in machine, it has a framework that is used for adding warp thread, described framework is vertically to be arranged on a next door in order to the wire-cutting device that cuts off warp thread basically, wire-cutting device is arranged on a fixing position in first marginal zone of framework, and framework is along guiding with become vertical direction by the plane that added warp thread constituted in first marginal zone, and be connected so that can on the direction of a main shaft, be shifted with wire-cutting device, and in second marginal zone, framework is installed movably, and is directed to so that become perpendicular or parallelly to be shifted in the direction of a main shaft and with the plane.

From EP0, known in 446,326 have a device, and its middle frame is hanging with the warp thread that is added, and carry out vertical shift so that can cross in the basic pillar of whole drawing-in machine one.Wire-cutting device also is mounted in the fixed position of same basic pillar.Therefore framework can be parallel to the warp thread group of adding together with added warp thread and move in the wire-cutting device front.Wire-cutting device progressively cuts off other warp thread so that they are drawn in the comprehensive light of loom.

A shortcoming of this known devices particularly in: wire-cutting device and framework all are mounted on the basic pillar, and their relevant position is limited by the relative position with basic pillar.This means that the position on the warp thread plane that is added and the position of wire-cutting device are to guarantee by thread-carrier and the supporting member that is contained on the basic pillar.Sometimes this thread-carrier and supporting member are very long and easy deformation, and have the gap.Therefore the degree of accuracy in the position of the wire-cutting device of warp thread front is extremely limited.This means that if the accuracy requirement of position is high more the rigid design of then described supporting arrangement and thread-carrier requires also high more, weight is also heavy more.

From EP0, know that also another kind of device is arranged in 541,268.Here framework is to be arranged on the wire-cutting device on the fixed position and to move with respect to one equally.Framework is to guide in a mode that tilts in the first top edge district.This device uses in restriction under the occasion of possibility of the extraordinary yarn be applicable to liposuction technique has some shortcomings, i.e. the guiding of framework can not guarantee satisfactorily all the time that thread layers warp thread just to be cut off introduces yarn reliably and cut off in element or the wire-cutting device.

Therefore indicated as feature in the claims, task of the present invention is to provide a kind of device of simple and lightweight described type, and warp thread wherein to be cut off and wire-cutting device are located mutually as far as possible exactly.

Combination according to the various features of independent claims 1, this task is finished like this: framework is installed in a marginal zone movably, and be directed to be shifted along a direction, and can be with wire-cutting device together at same direction superior displacement in another marginal zone, and framework directly be connected with shearing device.Preferably framework is having a distance mutually and is being positioned at channeling conduct on the leg-of-mutton angle 3 at least, specifically, be guiding on 2 positions, and only resist the guiding of lateral position in one direction on the position at least on one point antigravity and the lateral displacement on a certain direction.The position of this last point is to be positioned at yarn to cut off element or wire-cutting device close vicinity all the time.Also can on other point, be used for guiding to side direction displacement.Further details according to apparatus of the present invention can obtain from dependent claims.

By the obtainable advantage of the present invention particularly in: cracked ends yarn to be cut rests on the tram point of wire-cutting device front all the time exactly, though basic pillar whether because the weight of framework and local deformation, perhaps whether framework twists.Therefore warp thread can be cut off reliably and be need not by means of having the heavy especially device strong with rigidity.

And by embodiment and with reference to accompanying drawing that the present invention is described in detail is as follows, wherein:

Fig. 1 represents a perspective view of this device;

Fig. 2 represents a sectional view by this device.

Fig. 1 represents one according to device of the present invention, and it has one and is used among the interpolation figure the not framework 1 of the warp thread of expression.Framework 1 is mainly by two horizontal bearing bodies 2,3 and 4,5 compositions of two vertical support frames.The guide rail 6,7th that warp thread is used is installed in the place ahead on the horizontal bearing body 2,3 with the method for knowing, and therefore described warp thread is positioned at mutually on an area or the plane successively.In addition, there is an additional guide rail 8 to be installed on the upper level supporting body 2, and is used for guiding frame 1.Two rollers 9,10 are installed on the lower horizontal supporting body 3 movably, or also may be contained on the support 4,5.These two rollers are supported on the fixed guide 11 and can move thereon.In the first top edge district 12 of framework 1, there is a wire-cutting device 13 to be installed on the fixed position on framework 1 next door.Described device is to be installed on the principal post of the drawing-in machine of not representing among the figure with the method for knowing.Wire-cutting device 13 has a pair of roller 15 as deflector roll on its shell 14, and guide rail 8 can move between roller.Foregoingly be used for movably that the roller 9,10 of supporting frame 1 is arranged in second marginal zone 16 of framework 1 bottom.Other has a roller 19 to be installed on the position of fixing by parts 28 that are connected on the wire-cutting device 13 equally, is supporting a clamping guide rail 27 of only partly representing in the side of described roller.Other devices, for example being used for brush crossbeam 17 grades of tensioning warp thread also is to be contained on the framework, but these devices have all been known and are unimportant to the present invention.

Fig. 2 represents the element same with Fig. 1 once more, therefore all marks with identical code name.But these elements no longer here have been illustrated one by one.But in the case, have only the shell 14 of wire-cutting device 13 is represented partly.Just can be more clearly visible guide rail 8 is so here guided in a pair of roller 15 or between the roller 15.Here also expressed by one group of warp thread 18 of guide rail 6,7 location.

According to device of the present invention, its method of operation is as follows:

One group of warp thread 18 is added to the front of guide rail 6,7 with the method for knowing, and for example by the 17 further tensionings of brush crossbeam, and is fixed, and that is to say to lead by clamping changes 27 (Fig. 2) and be clamped on the guide rail 6,7.For this purpose, displaceable framework 1 is moved to a position 1 on guide rail 11, and wherein a pair of roller 15 is positioned at rail and leads an end of 8.In the case, clamping guide rail 27 leans against on the roller 19 in the bottom.This moment, 18 leaps one of warp thread group were parallel to the area or the plane 20 of the main shaft 21,22 of guide rail 8 and 11.For the purpose of cutting off independent warp thread, framework 1 station the direction of main shaft 21,22 and moves.In the case, framework is directed resisting and guide rail 11 or 22 one-tenth horizontal displacements of its main shaft with the both direction that is equivalent to arrow 23,24 on guide rail 11 by roller 9,10 in marginal zone 16.

In marginal zone 12, framework 1 is only resisted in the displacement of arrow 23 directions by fixing a pair of roller 15 and guide rail 8 and is directed.In marginal zone 16, framework 1 is directed with the direction of arrow 23 by fixing roller 9 and extraly.In the case, framework 1 is with himself weight and be pressed on the roller 19.Roller 9,10 preferably is connected on the framework like this, makes it pass through joint 30 and can rotate or tilt.Simultaneously, these joints are preferably arranged in the framework plane of gravity yarn are cut off a side of element, so that make framework 1 static reliably, the horizontal component with its deadweight acts on the roller 19 basically.

In other words, framework 1 is to install or be guided in A at least, on the B, 3 of C, also can select an annex point D.On B and C point, framework is to be directed along main shaft 22.On A and D point, framework is to guide with the direction of arrow 23.The great advantage of this solution is: the guiding of framework 1 can be positioned at very near wire-cutting device 13, also is: framework can cut off the contiguous A point of element at yarn especially exactly, preferably also at the D point to be guided with the 20 one-tenth horizontal directions in plane.This has guaranteed that also warp thread enters yarn exactly and cuts off element.Contiguous at wire-cutting device 13, warp thread group 18 remains on a steady state value 25 with the distance of the outer boundary 26 of shell 14.Though but be actually the relation that has guaranteed for the cut-out element of not representing among the figure but all knowing.Even so for example under the situation of guide rail 8 bendings, warp thread to be cut off also can be located exactly.Obviously, if roller 15 suitably designs, it also can absorb the gravity effect, thereby framework 1 can partly be suspended on the wire-cutting device 13 at least.Roller 19 is with clamping guide rails 27 guiding frame 1 exactly together, particularly work as roller 9,10 when the accurate guiding that can not guarantee on the guide rail 11 on arrow 23 directions, also particularly because roller 9, if 10 swing or the problem that tilts to connect are when framework 1 some distortion.

Other advantages of the present invention comprise: can exempt safely the frame of guiding frame, this The kind frame must have the width of twice warp beam at least. This means can be more easily near device, And can make the weaver that required provision for disengagement is set at the scene to be used for removing any device. In addition because of For framework guides according to the present invention, so the production cost of this device can subtract significantly Few.
