Description
Technical field
The present invention relates to isolate from thread layer the device of quantitative yarn, the yarn of this thread layer is being tightened up on two positions at least, can isolate a yarn from thread layer by a separating mechanism.The present invention also relates to from thread layer, separate the method for yarn.
Background technology
For example, yarn separately or to separate be such operation, promptly for example in the harness threading spare of warp thread being drawn in braiding machine and must carry out this operation.In this case, warp thread is tightened up in such framework, and promptly there, they form a thread layer jointly.In addition, some yarns lean on very closely mutually.Before being threaded into, they should be separated from thread layer, and promptly they must be separated from each other.In this case, the purpose of separating draw thread is to prepare out quantitative yarn and especially a yarn for the processing of subsequent handling.Another purposes is that a warp thread that has obtained the old thread layer of weft yarn is received on the new thread layer.Here, warp thread also is tightened up in a framework and must separates from thread layer before with the Warp tying machines tying-in.
In known yarn separating mechanism and method, for example separate pin and from thread layer, isolate top yarn with one.In this case, the separation pin falls on the top yarn of this layer and by a groove that is matched with the yarn cross section that separates pin by the motion that is approximately perpendicular to the thread layer plane and clamps yarn.In this case, unsatisfactory is must very accurately be matched with each yarn size owing to separate pin, so must a large amount of different separation pin of storage.In addition, separation process is not reliable especially.Therefore, especially relevant with filament yarn ground needs one as the so-called lease making spare that separates supplementary means.This lease making spare must be added in the thread layer in advance, and here, two ropes of laterally putting along warp thread are drawn into or enroll between the warp thread.By seesawing of lease making rope, yarn is Always On Top separated with other yarn and is branched away with separating pin subsequently.
A shortcoming of this known method and device is that especially it is limited separating with the separation pin in the warp thread that many so-called multifilament are formed.Here, be difficult to not clamp all monofilament of a yarn with not using lease making spare but the monofilament of not clamping adjacent yarn is arranged.Especially do not twist, have little number or thread layer density when very irregular when these multifilament, situation is especially true.Even utilize the method for lease making spare, also must separate with hand or by machinery, so that be encased inside rope, therefore, at this problems referred to above have appearred also.Although bobbin magazine is fitly separated and put into to warp thread by lease making spare, be encased inside the separation rope and mean extra and common very bothersome work.But, at braiding or warp thread when having tied a knot, separate irregular warp thread and cause and shut down and and then cause productivity ratio unsatisfactory.This in addition occur in and used as under the situation that is used in the dual yarn recognition system in the Warp tying machines.
Disclose other method from FR 698064 or GB 2117419, wherein do not used lease making spare and only carry out the operation of separating draw thread from thread layer by a rotary body, the outer peripheral face of described rotary body has screw thread form.But described method only is applicable to the separation of staple fibre or twisting multifilament.For the untwisted yarn that is made of many long filaments, yarn only is divided into some monofilament.Therefore, almost can't carry out neat separation.
At last, disclose a kind of device in US 4723346, one of them lease making spare is encased inside in the thread layer.The two ends of lease making rope are being provided with along its longitudinal extension direction basically with laterally can distinguishing relative motion.As a result, every yarn can leave the crosspoint and can pay out the yarn Always On Top of a thread layer.Isolated top yarn is booked by suction nozzle and is sent from this thread layer from this thread layer thus.But this moment, a yarn is promptly isolated in real separation process from thread layer process has realized by known in many ways lease making form.Suction nozzle only is used for seeing off isolated yarn.This device is not satisfied to be, lease making must be arranged, and it will be added into very bothersomely or be drawn out of thread layer.
Summary of the invention
Therefore, task of the present invention provides a kind of apparatus and method, by these apparatus and method, can be without difficulty as far as possible and only with operation seldom but carry out reliably from the thread layer separating draw thread, and especially when thread layer has difficult yarn that separates such as untwisted multifilament.
In order to finish this task, the invention provides a kind of device of from thread layer, isolating quantitative yarn, these yarns of this thread layer are tightened up on two positions at least, at least one yarn can be separated from this thread layer by a separating mechanism, described device is provided with an aspirator, can produce negative pressure by this aspirator, described device is provided with a drive unit, can this aspirator be moved relative to this thread layer by this drive unit, at described aspirator during relatively near this thread layer, described negative pressure can cause at least one yarn towards this aspirator deflection, it is characterized in that, also be provided with a checkout gear, can carry out the inspection of separating resulting by this checkout gear, described aspirator has suction nozzle, and this suction nozzle is equipped with and holds yarn portion and suction slot, the extension trend of this suction slot is directed abreast with a yarn to be separated basically, and the width in one slit of described aspirator is less than the longitudinal extension distance of the cross section of a yarn to be separated.
The present invention regulation, preferably only by aspirate one or more yarn make it or they separate with the thread layer that is tightened up.Major advantage of the present invention is, in order to isolate a yarn the yarn that is tightened up from one deck, must adopt a pre-separation lease making spare neither resembling in the prior art, also needn't allow separating mechanism insert in this layer.In the device of known the above-mentioned type, cause detachment defects between insert layer or two yarns.According to the present invention, do not need to insert, because yarn to be separated is separated with thread layer by a pulling force, described pulling force is applied on this yarn from the thread layer outside.Especially do not need side to clamp yarn to be separated.Equally, can eliminate separating mechanism and hook the monofilament that constitutes by one or more other yarn, thereby the present invention is particularly useful for the separation of this yarn.Therefore, solution of the present invention also can be used in separation critical yarn such as spun yarn and filament yarn and can irrespectively use with the roughness or the fiber number of yam surface.
According to the principle of the invention, promptly pulling force is applied on the yarn that is tightened up between the tightened position and described pulling force has at least one horizontal component along yarn longitudinal extension direction, can isolate any yarn in principle from thread layer.At present, always can only so isolate top yarn from thread layer, promptly this yarn is separated by such motion, and described motion is carried out in the thread layer plane that is made of thread layer basically.On the contrary, the present invention also can so catch one to eradicate two yarns beyond the yarn of the outside, promptly this aspirator and thread layer are moved to this root yarn in a supply campaign that is approximately perpendicular to this thread layer and bleed, subsequently, this root yarn is separated on a direction with this supply reverse movement.
General provision is only separated a yarn respectively from thread layer.By the size and/or the suitable nozzle structure of suitable negative pressure or suction, also can side by side many yarns be separated from this thread layer basically.
In the present invention, aspirator can have the slit one, comes suction air by this slit, wherein gap width less than or equal yarn cross section extended distance on the gap width direction at the most.One realized that thus the yarn that is held is not brought in the slit, but blocks this slit.On the one hand, this has increased the suction that keeps yarn; On the other hand, this slit thus can be closed basically, the result, and other yarn of this layer can not attracted.
According to vacuum magnitude, yarn to be separated because of deflection from aspirator back at regular intervals near this aspirator.In addition, in order to simplify the further processing of yarn, can replenish regulations, aspirator and the yarn that just was tightened up on two positions of a framework originally leave thread layer together, and the yarn clamping part is in this aspirator.This has simplified yarn and has been passed to the treating apparatus that comes into operation subsequently from aspirator.
By as comprising the checkout gear of an image recognition system, can advantageously control device of the present invention and control method process.For this reason, for example can identify a yarn from when being positioned near the aspirator, so that be controlled between aspirator and the yarn further approaching.By this checkout gear, can determine whether that also this aspirator catches and take away yarn to be separated.Also can determine, in fact whether isolate a yarn (being called as dual yarn identification).If checkout gear is determined current the separation and gets nowhere that then it can impel a control device to repeat this process.For this reason, in a preferred embodiment of the invention, can form a control circuit, its regulation, separation process repeats always, judges vacuum noz(zle) up to this checkout gear and in fact separates a yarn.Because the separation of yarn only need be in the relative translation between thread layer and one of them separating mechanism, so even if under the situation of using control circuit, also can realize very apace separating.
As a replacement scheme of optical detection apparatus, also can be applied to tension force on the yarn with a condenser type or the measurement of piezoelectric type checkout gear.The deflection that is caused by suction nozzle has increased yarn tension, and the predetermined value that wherein reaches yarn tension may be the standard that a yarn is isolated in success.

Description of drawings
Embodiment shown in the signal describes the present invention in detail in conjunction with the accompanying drawings.Wherein:
Fig. 1 is as first embodiment of apparatus of the present invention and the perspective view of thread layer;
Fig. 2 is the sectional view at the suction nozzle at thread layer edge;
Fig. 3 represents the device shown in Figure 1 that a yarn is separated.
The specific embodiment
Fig. 1 illustrates a thread layer 1, and it has many equally long basically and yarns 2 that be parallel to each other and extend, and described yarn is clamped in a unshowned suitable clamping device respectively on the two ends 3,4.Continuous yarn 2 is the same distance in space ideally, but also can be spaced apart differently, and this does not influence function of the present invention.Therefore, all to be positioned at a plane be the thread layer plane to these yarns 2.Thread layer 1 does not contain lease making spare.
Fig. 1 also illustrates the light source 6 (as light emitting diode) of gamma camera 5 and below the thread layer plane that places top, thread layer plane, and they all belong to an optical detection apparatus.Gamma camera 5 and light source 6 are on same optical axis 7, and this optical axis is substantially perpendicular to the thread layer plane at least.
An aspirator 8 is arranged between gamma camera 5 and the light source 6, and arranged side by side with it is a separating mechanism as for example pin 9 that separates shown in Figure 1.Aspirator 8 with separate the shooting district that pin 9 all is positioned at gamma camera 5.
Gamma camera 5, light source 6, aspirator 8 and separate pin 9 and constitute a construction unit according to the mode of not describing in detail are as by being arranged on the same bearing.Therefore, these parts can be together with the thread layer plane parallel move.A drive unit that also is not shown specifically is set for this reason.In addition, aspirator 8 is configured to and can moves on construction unit, thereby aspirator 8 can move relative to gamma camera 5.
Gamma camera 5 can have a cmos sensor that 640 * 480 pixels are for example arranged.In this sensor, the quantity of the pixel that effective pixel is promptly paid attention in signal is handled is variable.Need improve with the pixel number minimizing than summarizing overall shooting pixel and accessible picture frequency still less because the details of separation process is taken, when details was taken, picture frequency can be apparently higher than overall shooting.Therefore, in real separation process, take and grasp situation about changing very apace and make a response by details.
Gamma camera has first interface, and it becomes the form of asynchronous serial port such as standardization LVDS (low-voltage differential signaling) interface.By this interface, control signal such as dimension of picture, time for exposure etc. are passed to gamma camera from unshowned higher level's control device.The captured image of gamma camera can be passed to a digital signal processor (DSP) by another LVDS interface of gamma camera.This digital signal processor is equipped with traditional image analysis software, by this software, can determine some yarns and other yarn and aspirator and the position of separating pin relatively relatively.
The analysis result of digital signal processor is passed to this control module again, and this control module is controlled aspirator 8 and separated moving and function of pin according to analysis result.
Fig. 2 is expressed as the aspirator 8 of suction nozzle 12 forms and near the cross section of the yarn at thread layer 1 edge.As shown in Figure 2, relative thread layer plane 13 symmetries and the aspirator 8 established has a conical nozzle portion 14, it has infundibulate nozzle face 14a, the 14b of two relative tilts.Two folded angular aperture α of nozzle face 14a, 14b can be selected from 30 °-130 ° and also preferably equal 90 °.Spray nozzle part 14 has the suction slot 15 of constant gap width h to be communicated with one.As shown in Figure 2, gap width is less than the diameter D of the cross section of a yarn 2.In this embodiment, gap height h approximates half of diameter D.
One only illustrates local suction chamber 16 at Fig. 2 links to each other with suction slot 15, and a pipeline 17 (Fig. 1) is communicated with suction chamber 16 again.A pressure p is arranged in suction chamber 16
1, p wherein
1Less than environmental pressure p
0p
1With p
0Difference for example can be 0.6 crust.A unshowned negative pressure pump (or vavuum pump) or jet pump are connected with pipeline 17, can produce negative pressure by it.
In order from the thread layer of no lease making spare, to isolate top yarn 2a with this device, the construction unit of band suction nozzle 12 near top yarn 2a, photographs those top yarns 2 of thread layer 1 or at least that root top yarn 2a up to video camera 5 by a feed motion that is produced by drive unit.In this case, feed motion is carried out along arrow 18, this arrow thread layer plane 13 interior orientations and basically with the capwise of yarn 2.Because control device has been grasped one and has been taken the yarn that is detected on district's outward flanges with the distance between the suction nozzle 12 at video camera 5, thus this suction nozzle now can by along the predetermined continuation mobile alignment of direction of feed (arrow 18) near first yarn 2a.Perhaps, this control device can be controlled suction nozzle 12 near yarn 2a by the measurement result of checkout gear.Along with this suction nozzle further near yarn, it is that fixed gamma camera moves relative to now on direction of feed.Therefore, can determine the backhaul of aspirator 8 and the Distance Remaining that still stays by gamma camera apart from yarn 2a.Figure 1 illustrates this situation.
Along with near the still undeflected yarn 2a in thread layer, owing to the air-flow that has negative pressure and cause thus in suction nozzle and before the suction nozzle, described yarn is inhaled to suction nozzle 12 more and more doughtily towards suction slot 15.As a result, yarn 2a is deflected to suction slot 15 with its part relative with suction nozzle 12.In order to obtain maximum degree of deflection, suction nozzle 12 should be admitted on the centre position between the yarn end 3,4.
The feeding of yarn 2a is moved and deflection has produced such result, and promptly yarn 2 is with reclining suction slot 15 and seal this slit of its that part of in suction section, as shown in Figure 2.The pressure reduction of (promptly at suction slot 15 and be right after between the zone in the nozzle segment 14 behind yarn 2a) increases thus because the yarn both sides, so confining force has also increased, yarn 2a is maintained in the suction nozzle 12 by such confining force.
Now, suction nozzle 12 is together with leaving thread layer 1 (arrow 19) on the present direction opposite with direction of feed (arrow 18) of yarn part that is kept by it.In addition, originally fixed video camera 5 and the analytic unit of the control device that becomes the digital signal processor form that is attached thereto are determined whether suction nozzle 12 really obtains and have been held a yarn 2 and whether really only held top yarn 2a.As long as video camera determines to have held a yarn, then the corresponding signal according to this control device stops dropping back mobile.If can not determine, then end negative pressure and perhaps return the yarn that has held, then, produce negative pressure again and repeatedly repeat described so far yarn acquisition methods, determined to obtain correct yarn up to this analytic unit.
If this analytic unit detects the yarn 2a that correctly obtains the front, then separate pin 9 and be inserted in now in the expansion slit between top yarn 2a and the follow-up yarn 2b.Like this, top yarn 2a is separated from thread layer 1 uniquely or separates and be used for follow-up processing or processing.In this way, all yarns 2 of thread layer 1 can be separated one by one.
