Yarn guide portion 35 is for being formed with the tabular sheet material of the recess for guiding yarn 21.Guide yarn 21 that the crank motion of traversing can be prevented to be delivered to side, upstream by yarn guide portion 35.Further, yarn guide portion 35 guides the position of yarn 21 to become the fulcrum of traversing.
Then structure and the configuration of traversing detecting sensor 70 is described in detail with reference to Fig. 3 to Fig. 6.
As shown in Figure 3, above-mentioned cap 29 is made up of with the backplate (the 1st plate) 82 being configured in side, the back side (coiler drum 28 side) the front plate (the 2nd plate) 81 being configured in side, front (side contrary with coiler drum 28).Front plate 81 and backplate 82 is spaced apart is arranged in parallel, the yarn 21 of traversing is by therebetween.Further, front plate 81 avoids the middle ground setting in traversing region.
As shown in Figure 6, front plate 81 is formed with the hole portion 81a of through shape, overleaf plate 82 is formed with the hole portion 82a of through shape.Hole portion 81a and hole portion 82a are formed on corresponding position (being position identical on the direction orthogonal with traversing region in detail).
On cap 29 throughout whole implementation electroplating processes.The kind of this electroplating processes is arbitrary, preferably zinc-plated or chromium plating (hard chromium plating).Further, cap 29 also can be made for stainless steel, omit electroplating processes.
Traversing detecting sensor 70 is configured in the one end in traversing region.Be more specifically be configured in the end regions side (with reference to Fig. 4) along package Width, traversing region being divided into the non-central authorities in 3 regions.In addition, the traversing detecting sensor 70 of this example is also be configured in the region of most end when being divided into 4 regions.As shown in Figure 3 and Figure 6, traversing detecting sensor 70 possesses housing 71, light-projecting portion 72, light accepting part 73, reflecting part 74 and sensor controller 75.
Housing 71 is box shape assembly, is arranged on side, the back side (yarn 21 passes through opposition side by the opposite side of side, yarn) (with reference to Fig. 6) of backplate 82.Housing 71 is provided with light-projecting portion 72 and light accepting part 73.Further, housing 71 is provided with sensor controller (control part) 75.This sensor controller 75 carries out the signal that proper transformation is obtained by light accepting part 73, the process etc. exported to unit controls portion 30.
Because light-projecting portion 72 is arranged on housing 71, be therefore positioned at the side, the back side (yarn passes through opposition side) of backplate 82.Light-projecting portion 72 can project the light such as infrared ray from hole portion 82a towards front plate 81 side.The light passing hole portion 82a that light-projecting portion 72 projects, between front plate 81 and backplate 82, (the yarn road that the yarn 21 of traversing passes through) and hole portion 81a project on reflecting part 74.
As shown in Fig. 3, Fig. 5 and Fig. 6, reflecting part 74 is spaced apart being configured in than the plate-shaped member of front plate 81 by side, front (yarn passes through opposition side).Reflecting part 74 part extending to side, front from side, the back side is bearing in the outside of front plate 81.Further, reflecting part 74 is configured on the position corresponding with hole portion 81a and hole portion 82a.Reflecting part 74 is also implemented to the electroplating processes such as zinc-plated or chromium plating (hard chromium plating).Or, reflecting part 74 also can be made for stainless steel, omit electroplating processes.
Light accepting part 73 is the same with light-projecting portion 72, is positioned at the side, the back side (yarn passes through opposition side) of backplate 82.Therefore, the side in the yarn road that the yarn 21 that light-projecting portion 72 and light accepting part 73 are both positioned at traversing passes through, reflecting part 74 is positioned at other side.The light that light accepting part 73 light light-projecting portion 72 projects, reflecting part 74 reflects.Light accepting part 73 generates the detection signal of the magnitude of voltage corresponding with the light quantity of light.
When yarn 21 does not cross traversing detecting sensor 70, the magnitude of voltage of detection signal is roughly fixing.But when yarn 21 crosses traversing detecting sensor 70, because light is blocked by this yarn 21, therefore the magnitude of voltage of detection signal reduces.In the moment that the magnitude of voltage of detection signal reduces, sensor controller 75 judges that yarn 21 has crossed, export judged result to unit controls portion 30.
In above-mentioned such method in the past detected from the reflected light of yarn, be difficult to detect light absorbing color yarn (with reference to Fig. 7 (b)).To this, detect yarn 21 by time light quantity the high crape of the absorptivity of method to light of this example of minimizing naturally can detect, because white yarn also absorbs light to a certain degree, therefore dialogue yarn also can detect.Therefore, the light quantity that need not increase light-projecting portion 72 just can detect various yarn.
Wherein, as shown in Figure 3 and Figure 4, light-projecting portion 72 and light accepting part 73 along the yarn 21 of detected object direction of travel configure.Thus, the yarn 21 of traversing crosses light-projecting portion 72 and light accepting part 73 simultaneously.As shown in Figure 6, the light that light-projecting portion 72 projects is blocked by yarn 21 result, and light quantity reduces, and the light that reflecting part 74 reflects is blocked by yarn 21 again, and light quantity reduces further.Therefore, it is possible to improve the accuracy of detection of yarn 21.
Then, the structure of the accuracy of detection for maintaining traversing detecting sensor 70 is described.
When reflecting part 74 has been implemented electroplating processes, can not only reflectivity be improved, can also intensity have been improved, be not easy injured.Continue to maintain reflectivity thereby, it is possible to long-time.Further, when reflecting part 74 is stainless steel, due to can be antirust, continue to maintain reflectivity therefore, it is possible to long-time.
But, between front plate 81 and backplate 82, sometimes there is the splashing such as fiber or wax of yarn 21.Therefore, fiber etc. are attached on light-projecting portion 72, light accepting part 73 or reflecting part 74 sometimes.When being attached with fiber etc., because light has been blocked by this fiber etc., therefore the accuracy of detection of yarn 21 has reduced gradually.Consider this point, in this example, achieve 2 countermeasures.
First countermeasure is the method for the light quantity of the light that adjustment light-projecting portion 72 projects.Cross as long as no yarn 21 in this example, light accepting part 73 should detect fixing light quantity.Therefore, preset the predictor of the light quantity of light accepting part 73 light when not having yarn 21 to cross in this example, make the light quantity of light accepting part 73 light for this predictor control light-projecting portion 72.Be specially, sensor controller 75 obtains the deviation between light quantity that predictor and the actual light of light accepting part 73 arrive.Then, sensor controller 75 is added deviation and is also added the differential value or integrated value etc. of deviation according to necessity, thus makes deviation carry out controlled reset with diminishing.
Thus, even if hypothesis fiber etc. are attached on light-projecting portion 72, light accepting part 73 or reflecting part 74, owing to can increase the light quantity of light-projecting portion 72 with corresponding, therefore, it is possible to prevent the accuracy of detection of yarn 21 from declining.Further, owing to not being always but increasing the light quantity of light-projecting portion 72 according to necessity, therefore compared with the mode in the past of carrying out under the state always increasing light quantity detecting, inhibit the load of light-projecting portion 72, thus can life-saving.
In addition, because the light quantity of light-projecting portion 72 also exists limit, therefore when needing the light quantity of more than specified amount, even if or to continue to carry out the situation that controlled reset deviation also do not reduce at the appointed time inferior, also can give the alarm.
Second countermeasure is for easily can carry out cleaning this point.Reflecting part 74 is configured on the position leaving front plate 81 in this example, and the space opening between light-projecting portion 72 and reflecting part 74.Therefore, by the surface of wiping light-projecting portion 72 grade of being assigned to these opening portions of insertion such as thin bar-like member, the fiber etc. be attached in light-projecting portion 72 grade can be removed.In addition, also can according to the alarm controlled reset of light-projecting portion 72 being sent to the cleaning of urging light-projecting portion 72 grade.
The variation of above-mentioned example is described referring to Fig. 8.In addition, in the explanation of this variation, sometimes on drawing, add identical mark for the same or similar parts of aforementioned example, omit the description.
For to separate with front plate 81 structure possessing reflecting part 74 in above-mentioned example.To this, a part for front plate 81 in this variation, is made to play reflecting part 74.That is, the light of light-projecting portion 72 projection is by the backside reflection of front plate 81, this reflected light of light accepting part 73 light.
Thus, although compared with above-mentioned example cleaning expense time, can amount of parts be suppressed.Further, when like this with front plate 81 reflected light rays, preferably the electroplating processes such as zinc-plated or chromium plating (hard chromium plating) are implemented to the whole front plate 81 comprising reflecting part 74.Or, the whole front plate 81 comprising reflecting part 74 also can be made to be stainless steel, to omit electroplating processes.
As described above, automatic bobbin winder 1 possesses winder 26 and traversing detecting sensor 70.Winder 26 limit makes yarn 21 traversing limit reel.Traversing detecting sensor 70 is configured in yarn 21 and is wound in the traversing region of portion 26 traversing, detects the yarn 21 of traversing.Traversing detecting sensor 70 has the light accepting part 73 of the light that light-projecting portion 72, the reflecting part 74 reflected by the light projected from light-projecting portion 72 and light are reflected by reflecting part 74.Traversing region is divided on the position in any one region in 2 regions at the two ends in 3 regions along package Width by the position and detecting that light accepting part 73 and reflecting part 74 are configured in the yarn road that the yarn 21 that clips traversing passes through.
Thus, light-projecting portion 72 projects, the light that reflected by reflecting part 74 owing to being blocked by the yarn 21 of traversing, therefore light quantity reduces.As a result, the yarn 21 of traversing can independently be detected with the color of yarn.And, because traversing detecting sensor 70 is configured in the end regions in traversing region, therefore, it is possible to reliably detect state that traversing region diminishes, be wound up into ribbon wound in a part for package or yarn 21 circumvolution to undesirable conditions such as the drum windings on drum to yarn 21 not traversing.
Be explained above preferred example of the present invention and variation, but said structure such as can change as follows.
Although light-projecting portion 72 is configured in downside (side, upstream) in above form, light accepting part 73 is configured in upside (side, downstream), also can be conversely.Further, although light-projecting portion 72 and light accepting part 73 are formed integratedly in above-mentioned form, also can separate.In this case, although the degree of freedom of layout improves, the position adjustment of light-projecting portion 72 and light accepting part 73 becomes difficulty.
Further, traversing detecting sensor 70 also can be configured in the end regions of opposite side (side, unit controls portion 30).Further, also can light-projecting portion 72 and light accepting part 73 be configured in front plate 81, reflecting part 74 is configured on backplate 82.In this case, the maintaining of light-projecting portion 72 and light accepting part 73 becomes easy, but the cleaning of light-projecting portion 72 grade becomes and takes time and energy.
Although carry out traversing with the coiler drum 28 being formed with traversing groove in above-mentioned form, arm-type, belt, revolving traverse gear also can be used.In this case, the roller not forming traversing groove can be used as help roll.Especially when using arm-type traverse gear, by traversing test section being arranged on the central portion of the traversing width of traverse guide, even if when produce yarn do not engage with traverse guide the traversing caused bad, multiple traversing test section also need not be set and just can detect that traversing is bad.And, even if Patent Document 2 discloses when to change traversing width in arm-type traverse gear, also do not carry out this distinctive effect of necessity of the position adjustment of traversing test section.When so arm-type traverse gear, by traversing test section of the present invention being arranged on the central portion of the traversing width of traverse guide, except effect of the present invention, the effect can also recorded in patented document 2.
Although sensor controller 75 carries out the control of traversing detecting sensor 70 in above-mentioned form, the control also can carrying out at least partially with unit controls portion 30.
The present invention is not limited to automatic bobbin winder, also can be applied in other yarn take-up devices such as rewinder and spinning frame (such as rotor spinner, free-end spinning machine).
