Abstract

A thread gripper (G) comprising a stationary first and second gripping element (G1,G2), which supports a thread clamping surface (K1,k2), . The thread clamping surfaces (K1, K2) can be pressed against one another with an adjustable contact pressure in a gripping position that holds the thread (Y) between the thread clamping surfaces. The thread gripper also comprises a setting element (S), which can be actuated out of a non-operative position by at least executing an opening movement, which can be brought into contact with the second gripping element, and which, at a time of thread release, adjusts the thread clamping surfaces over a thread release position until the thread gripper (G) is in an open position. In the gripping position of the thread gripper, an idle travel is provided between the setting element (S) and the second gripping element (G2). In the direction of the opening movement, said idle travel essentially corresponds to the travel path of the setting element during the acceleration phase thereof from the non-operative position up to an at least essentially constant speed and/or constant acceleration.

Description

Yarn gripper
Technical field
The present invention relates to a kind of yarn gripper that comprises fixing first clamping element and second clamping element that movably has another yarn clamping surface with a yarn clamping surface.
Background technology
This class yarn gripper (EP-A-0 756 028) for example uses at so-called annular storage device and textile machinery for example in the yarn road between the loom, or use the yarn of going up to stretch between twice is picked up at water-jet loom (JP-U-60-78885[58-169670]) to carry out stop, and discharge this yarn to insert yarn at each time point by the decision of weaving cycle.Except known cam drive yarn gripper, the yarn gripper that also has available magnetic force to open, wherein solenoid discharges second clamping element from first clamping element, thereby discharges at first by the yarn of stop so that the yarn running.In the yarn gripper that can utilize magnetic force to open, the switch magnet engages with second clamping element, and like this, the armature (iron) of second clamping element and switch magnet begins the action of opening simultaneously.During opening, in case the contact pressure between the yarn clamping surface diminishes, act on the suffered frictional force of yarn that tension force on the yarn can overcome the yarn clamping surface, yarn is setting in motion just.At open position, do not contact with the yarn clamping surface when in fact yarn turns round.When the armature (iron) of switch magnet and second clamping element at first when a boost phase is accelerated jointly, slowly quickened before this, increase gradually until reaching a constant substantially speed with post-acceleration, this be because the inertia of frictional force and quality in action, and magnetic force increases gradually, and for example the influence of variations such as the influence of the heating power situation of switch magnet, wearing and tearing, elasticity pre-determines to possible accuracy the real time point of yarn release in fact hardly or repeats this time point reliably also in action.Because armature (iron) and clamping element quicken jointly from static beginning, cause the release time of yarn uncertain, because inevitably the external action that changes makes the real time point of yarn release produce a time fluctuation.
Summary of the invention
One of purpose of the present invention provides as disclosed a kind of yarn gripper at the beginning, and it is very accurate to it is characterized in that yarn discharges predetermined time point.
Described purpose is realizing by following technical proposals:
According to yarn gripper of the present invention, comprise fixing first clamping element and second clamping element that movably has another yarn clamping surface with a yarn clamping surface, at clip position, its yarn clamping surface compresses under the effect of adjustable contact pressure mutually, the yarn of this clip position is sandwiched between two yarn clamping surfaces, a setting element, at least be driven from static the beginning by an opening action, thereby carry out mechanical engagement at the second clamping element place, and the yarn clamping surface of second clamping element that will be relative with the yarn clamping surface of first clamping element is adjusted to and crosses the open position that the yarn off-position reaches yarn gripper, wherein, at the clip position place, between the setting element and second clamping element, be provided with an idle running along opening the direction of motion.
At first, after setting element had consumed idle running, second clamping element began effect.Because second clamping element is apace, as within several milliseconds, carry out motion from static to the off-position, the situation that can not occur changing like this, but produce rapid and repeatably yarn point release time of explication of a quilt.The ectocine that changes still exists.But these influences are weakened when setting element is at first quickened separately.These external influence factors are negligible to the influence of clamping element, because clamping element begins action subsequently, but speed is very fast.At last, because the prediction to the startup of clamping element is more accurate than prior art, and clamping element reduces pressure more quickly from static beginning, promptly the time shorter as far as possible than prior art also will be shorter a period of time in reduce pressure, because these facts make yarn put and can accurately be kept release time.For the quick acting of clamping element, it is insignificant that ectocine just seems.
Because preestablished the size of idle running, setting element is at first accelerated to constant substantially speed separately, be with very fast when the time comes then and geostationary speed is collided second clamping element.Because second clamping element is with very fast speed, promptly big relatively acceleration slope is carried out the stroke of opening, and because the motion of the relative clamping element of boost phase of setting element can ignore, so the fluctuation of the time point that yarn discharges can not occur.Under the situation of magnetically-actuated setting element, can use highly dense, a light and cheap switch magnet, can select lower powered, because at boost phase, have only setting element to be driven, and after setting element has fully quickened and had very big acceleration energy, have only second clamping element to need to drive.
Idle running has caused time-delay, until the clamping element setting in motion.This time-delay is probably opened the cycle 1/2nd for begin to move count whole from setting element.Opening the cycle of yarn gripper, for example, sustainable 6.3 milliseconds.Like this, time-delay amounts to about 3 milliseconds.This has just determined to make clamping element carry out an opening action with speed how soon, and has shown the time point that reaches yarn release after clamping element begins to move with speed how soon.
Easily, setting element is defined by the armature (iron) or the fixator of switching magnet.This switch magnet is characterised in that relatively accurately predefined tensile force characteristic, this tensile force feature may be owing to external influence changes at boost phase, and this a part of feature that reaches geostationary speed or acceleration in the opening characteristics is can accurately be set as the gradient with regard to it by accurately predefined.
It structurally is simple adjusting contact pressure by a spring that acts on second clamping element.Adjust contact pressure enough greatly with at the clip position yarn of clamping and stop tension reliably.Maybe advantageously, use a spring, this spring has a long relatively spring-return and a suitable relatively elasticity of accurately setting is arranged.
Adjust onesize idle running for clip position, can be provided with a second switch magnet and/or a return spring or a permanent magnet at yarn gripper.The advantage of a second switch magnet be it can be when the first switch magnet be energized or even before demagnetization soon, it just can not produce perturbed force like this.
Permanent magnet is regulated armature (iron) at clip position, is the given default idle running of opening action subsequently, and this permanent magnet can be conveniently used for producing an action fast when setting element quickens beginning.This means: at first, the magnetic force of switch magnet increases, and is overcome until the resistance of permanent magnet.Up to this time point, setting element is not carried out any obvious action.In case the resistance of permanent magnet is overcome, in case same because armature (iron) motion, itself and the gap increase of permanent magnet, the drag of permanent magnet reduces suddenly, and setting element will significantly quicken.Subsequently, the armature (iron) that has been quickened greatly will clash into second clamping element.This snap action helps realizing the accurate setting to the boost phase of armature (iron), because what obvious effect the external action that changes does not have.
According to notion of the present invention, the yarn gripper of the coefficient yarn clamping surface with annular of preferred so-called disc-like.Yarn moves between the yarn clamping surface, and has crossed central shaft at least substantially.The endless yarn clamping surface has big clamping zone to yarn.Annular surface can be flat or can be ring grain or even can have a surface texture.This does not get rid of provides other forms of yarn clamping surface and/or clamping element, as plate-shaped or similar shape.
Realize the friction to second clamping element, the guiding of freely stretching fully with a tubular article and a conduit.
Pass the axle of the armature (iron) of tubular article bottom and guarantee that with the transmission device that is located on the axle power transmits along central shaft, and do not have other power.Idle running can be located between the transmission device and tubular article bottom that is fixedly mounted on the axle, or between the brake component on transmission device and the axle.In either case, to guarantee that all armature (iron) at first moves until reaching geostationary speed and/or acceleration in idle running, armature (iron) begins mechanically and the second clamping element acting in conjunction then, and carries the motion of second clamping element by the direction of opening.Because armature (iron) has had an obvious speed when clashing into second clamping element, answer between to use a buffer element to reduce wear.
During sliding catheter in using pipe, the friction law that can realize ideal to second clamping element.
And pipe can keep the spring of clip position to lead to being used to.If spring action is at the back side of the yarn clamping surface of second clamping element, the required contact pressure of clip position is directly transmitted in a certain position, is sent on the yarn at this position contact pressure.
Consider different tension force on different yarn qualities and/or yarn amount or the yarn, in order to make clip position and to contact pressure and can adjust, first clamping device being installed and/or being changed the preload of spring with adjustable form can be more convenient.
Preferably, yarn gripper is used for an insertion system, triggers a startup of depending on the insertion in loom cycle respectively.Insertion system comprises a special storage yarn feeding device, and this device is sent into insertion system with the several yarn circles in the tubulose winder structure under the situation without any internal support, disclosed as DE10051635A.Because in this case, when starting insertion, a plurality of yarn circles can be inserted and are not needed the internal support of winder apace, and can not expand substantially, thereby help in the yarn gripper that yarn point release time is accurately preestablished and with loom cycle coupling so that guarantee optimum insertion condition and short insertion time.
Description of drawings
By accompanying drawing embodiments of the invention are described.In the accompanying drawing:
Fig. 1 is a chart, and the opening characteristics of a general yarn gripper is described;
Fig. 2 is the chart according to the opening characteristics of a yarn gripper of the present invention; And
Fig. 3 is the longitudinal sectional view of a yarn gripper according to the present invention at clip position.
The specific embodiment
Fig. 1 has described the chart of opening of a general yarn gripper, and wherein the second clamping element G2 and setting element begin opening action at synchronization.Vertical axis is represented stroke S.Trunnion axis is represented time t.The horizontal line G1/G2 of upper end represents the position of first fixing on the clip position clamping element G1 and the position of the second clamping element G2.By under horizontal line F/G2 represent second clamping element yarn release time point open position in the stroke.Because the slope of opening curves A increases gradually at boost phase, thus its with by under horizontal line F/G2 still still relative straight when crossing.A relative velocity and/or acceleration at first appear afterwards, complete linear opening curves A with a very little angle with by under horizontal line crossing.Aging and the similar situation of the friction situation that changes, temperature regime, wearing and tearing, spring can change this boost phase, like this slope of opening curves at the very start than complete linear opening curves increase sooner (by under the part A 2 that dots) or increase slowlyer (dot on leaning on part A 1).This caused actual yarn point release time (curve A, A1, A2 with by under the vertical line of horizontal intersection point) drift.Because slope is still very little, the little deviation of boost phase will have very big influence to the drift of yarn point release time (between t1 and the t3).
Fig. 2 is the figure that opens according to a yarn gripper G of the present invention.Fig. 3 has shown this yarn gripper G.Represent the position of first and second clamping element on the clip position by last horizontal line G1/G2.By under the position of the horizontal line F/G2 representative second clamping element G2 when putting F release time, be to put F release time when the tension force that presents on the yarn begins to make yarn to move in case contact pressure diminishes.A represents the opening curves of setting element.B represents the opening curves of the second clamping element G2.Opening curves B begins to overlap with curve A from time point X.Owing between setting element and the second clamping element G2 one section idle running H is arranged, thus setting element when beginning to carry out boost phase second clamping element for example reached constant substantially speed without any action up to setting element.Yet, inevitably external action (by last and by under the curved path A1 and the A2 that dot) after setting element is by idle running A, no longer include any influence when moving with the second clamping element G2 (curve B).As common opening curves A, B with very large slope with by under horizontal line F/G1 when crossing, just cause yarn to put the generation of F release time, this time point accurately is limited to time t0.The whole opening action of the second clamping element G2 carries out along a very large part of slope of curve at faster speed, is produced yarn point release time that is accurately defined by this part.The external action that changes (aging, the temperature effect of frictional force, spring etc.) when the rapid movement of second clamping element to the not influence of some release time.
Fig. 3 has described the clip position of yarn gripper G.The yarns Y that is held has along the tension force effect of arrow Z direction.
Thread-guide element 2,3 is located in the support 1.Thread-guide element 2,3 defines the yarn road.A fixing clamping element G1 is fixed on and supports projection 5 places.The position of the first clamping element G1 can change arbitrarily by screwed hole 4.An endless yarn clamping surface K1 is flat in an illustrated embodiment, is arranged on the lower end of the first clamping element G1.The second clamping element G2 and first clamping element interact.Second adheres to that element G2 is designed to dish shape or discoid and ring gripping surface K2 also arranged.Described disk is formed by the flange 6 at the free open edge of tubular article 7.Tubular article is smoothly in the guide pipe 9.But between is provided with sliding catheter 10.Tubular article bottom 8 be opening and form a composition surface 15 at an upper portion thereof.As one of selection, composition surface 15 is made of the buffer element 16 that is located on the tubular article bottom 8.The direction of spring 11 is the lateral direction along pipe 9.Spring 11 is fixed and is acted on the back side of flange 6 by its upper end.As selection, the preload of spring is adjustable.
Switch magnet M is located at the lower end of support 1.Switch magnet M has a coil 111 and an inner armature (iron) 12, in case coil 111 be energized, armature (iron) 12 by from shown in the position of rising pull down.Axle 13 is connected with armature (iron) 12.Axle passes the bottom 8 of tubular article and have a transmission device 14 in tubular article 7.At illustrated clip position, yarn clamping surface K1, K2 exert pressure under the effect of spring 11 mutually to stop yarns Y to move.Armature (iron) 12 remains on shown position, at this moment on transmission device 14 and composition surface 15 idle running is arranged.Under the situation that clamping element G2 can move in the 6.5mm scope, idle running H is about 2.0mm.The size of idle running H shown in opening on the direction for example conforms to the stroke that keeps constant substantially speed and/or acceleration from static under the excitation of switch magnet M with transmission device 14.The speed that this means transmission device 14 and armature (iron) 12 strengthens in idle running H gradually to carry out boost phase, afterwards impact bonded face 15 and drive the second clamping element G2 shown in Fig. 3 and move along being directed downwards of fully open position of yarn gripper.
Behind transmission device 14 impact bonded faces 15, yarn clamping surface K1, the contact pressure between K2 reduces rapidly, and the tension force Z that presents on yarns Y is enough to put mobile yarn release time at real yarn.Afterwards, the second clamping element G2 further is adjusted to the yarn gripper full open position.
For coaxial better, axle 13 can for example move in the graphite bush at sliding catheter 20.Can be armature (iron) 12 equally and be provided with a coaxial sliding catheter 21.Perhaps, armature (iron) can be by the extension of the lower end secured core of the switch magnet M guiding of assigning to.
In case switch magnet M eliminates excitation, spring 11 makes yarn clamping surface K1, K2 mutual extrusion make yarns Y stop once more.Armature (iron) 12 is also driven upwards.As selection, can be provided with a second switch magnet 17, be used for armature (iron) 12 is adjusted to position shown in Figure 3, and/or be provided with the return spring 19 shown in.Return spring 19, same, can be located between composition surface 15 and the transmission device 14.In addition, may in the hole among the first clamping element G1, be provided with a magnet, shift transmission device 14 onto as shown in Figure 3 position, perhaps be preferably, at this moment in support 1, be provided with a little permanent magnet 18 adjacent with armature (iron) 12.
Permanent magnet 18 can be conveniently used for realizing armature (iron) 12 unexpected accelerated motion before bump second clamping element.The action force of switch magnet M increases gradually.The suction that permanent magnet 18 produces makes armature (iron) 12 remain on original position, and the size of suction depends on the gap size of 18 of armature (iron) 12 and permanent magnets, in case the interval width increase, suction sharply reduces.The switch magnet action force that is triggered increases, and this action force must at first overcome the suction of permanent magnet before armature (iron) begins to move.Because the action force of switch magnet M is very big at this time point, and since at this moment the suction of permanent magnet 18 sharply reduce, just realized the accurately default boost phase of desirable rapid movement and armature (iron) 12.Then, armature (iron) 12 will partly clash into second clamping element an opening curves that slope is very big, and second clamping element at this moment moves rapidly from inactive state and crosses the position that yarns Y is discharged.Because this function, the influence of outside variation can not apply tangible influence to the boost phase of armature (iron) 12 and can not apply tangible influence in the opening stage of the second clamping element G2.
In unshowned another embodiment, idle running H can be located between transmission device 14 and the composition surface 15, and 15 are located at the position of a certain lifting of axle 13.Transmission device 14 always is positioned on the bottom 8 of tubular article, and the composition surface on the axle 13 is offset to the distance of an idle running H upwards.In case coil 111 is energized, armature (iron) is pulled down and at first accelerate to a geostationary speed.Then, the composition surface bump transmission device 14 on the axle 13.Transmission device 14 will be with second clamping element G2 motion.Can between the composition surface on transmission device 14 and the axle 13, insert a return spring.
In illustrated embodiment, suppose that armature (iron) 12 and clamping element G2 carry out parallel and motion linearity.Different is, clamping element G2 even the motion or owing to the reason of armature (iron) produces strain of can pivoting.Yet no matter under the sort of situation, these all can take place when armature (iron) is used up idle running.In this case, a braking thin slice is pushed open from another braking thin slice or fixing bearing, perhaps can make the brake band strain.
