Test section 68 is determined to have the (mobile capture of yarn 14 in the case of the light of the intensity of the predetermined above is received in light accepting part 68b
Seizure successes of the portion 30a to yarn 14).
In addition, the structure of test section 68 is arbitrary, such as it can be the structure shown in Fig. 5 (b) to Fig. 5 (d).
In example shown in (b) in Fig. 5, pipe portion 32 (is located in the inside of 68 opposite side of test section across test position
The opposite side of test section 68 (light passes through portion 69)) possess reflecting plate 32d.In example shown in (b) in Fig. 5, light-projecting portion 68a institutes
The light of light projector is received after being reflected by reflecting plate 32d by light accepting part 68b.Herein, when yarn 14 in pipe portion 32 being present
Under, light is blocked by the yarn 14, therefore the intensity decreases of light that light accepting part 68b is received.Test section 68 judges by this way
The presence or absence of yarn 14 (whether the seizure of yarn 14 succeeds).So, the reflection of the light and at non-used yarn 14, and utilize yarn
14 block to light, and thus, even light absorbing colored yarn (especially crape line) can also carry out above-mentioned judgement.
In example shown in (c) in Fig. 5, instead of reflecting plate 32d using the inner surface of pipe portion 32 come reflected light.By
This, the accuracy of detection of yarn 14 reduces, but can utilize the presence or absence of simple structural determination yarn 14.
In addition, in Fig. 5 (b) and Fig. 5 (c), light-projecting portion 68a and light accepting part 68b and yarn 14 length direction
Arranged perpendicular, but can also be configured along the length direction of yarn 14.In this case, the not only light of light-projecting portion 68a institutes light projector,
The light reflected by reflecting plate 32d is also blocked by yarn 14, therefore the intensity of light is greatly reduced.Thus, it is possible to improve yarn 14
The judgement precision whetheing there is.
In example shown in (d) in Fig. 5, light-projecting portion 68a and light accepting part 68b across the light of pipe portion 32 to pass through portion 69
The mode of (test position) configures.The light of light-projecting portion 68a institutes light projector is kept intact after being blocked by yarn 14 and by light accepting part 68b
Receive.Thus, with Fig. 5 (b) and Fig. 5 (c) equally, this case can be blocked to carry out yarn by yarn 14 using light
The presence or absence of 14 judgement.In the structure of Fig. 5 (d), without setting reflecting plate, therefore cost can be reduced, also can in addition
Omit the labour for cleaning reflecting plate.
In addition, as long as test section 68 can detect the yarn 14 in pipe portion 32, however it is not limited to optical sensor, such as
Feeler etc. can be used, but by using optical sensor, can be from the outside yarn simply detected inside pipe portion 32
14。
Secondly, pipe portion 32 and light are described in detail by portion 69.As shown in figure 4, pipe portion 32 is by cylindrical portion 32a
Formed with connecting portion 32b.Cylindrical portion 32a is the part of the side of axle portion 31, the air flow circuit formed with section circle shape.Connecting portion
32b is connected to the cylindrical portion 32a end by the side of suction port 33, and in order to connect cylindrical portion 32a and suction port 33 and section shape
Shape is changing into slit-shaped from toroidal.In addition, suction port 33 is along the opening portion of the slit-shaped of the rotation direction of principal axis extension of package 22.
In the present embodiment, light is formed at the cylindrical portion 32a of pipe portion 32 by portion 69.In more detail, it is formed at phase
The position of connecting portion 32b sides is leaned in center than cylindrical portion 32a.Thus, the close suction that light is formed in cylindrical portion 32a by portion 69
Draw the position of the side of mouth 33, therefore the time untill detecting yarn 14 can be shortened.Also, connecting portion 32b is according to wide in width
Which of suction port 33 partly capture yarn 14 and position that yarn 14 is passed through is different.Thus, by the way that light is passed through into portion
69 are arranged on the position for avoiding connecting portion 32b, can prevent the accuracy of detection of yarn 14 and reduce.
In addition, as shown in figure 4, light is formed opposed with test section 68 when suction port 33 is located at catching position by portion 69
Position.Thereby, it is possible to realize rational simple layout.Even if the also, suction port 33 because of the winding thickening of package 22
Catching position changes slightly, and light will not also be changed by portion 69 with 68 opposed this case of test section, therefore can be without a doubt
Detect yarn 14 in ground.
In patent document 1 and 2, test section is arranged at suction port.Its reason is that quickly detecting suction port is inhaled
Draw the yarn captured.But for the structure, the distribution extended from test section can all be applied when turning round suction port negative
Load and distribution is tired.Also, as other structures, it is also known that more (attracting by inboard compared to axle portion 31 or axle portion 31
Mouthful opposite side be attract direction downstream) position set test section structure.But for the structure, until suction port
The yarn for attracting to capture just starts to detect untill reaching axle portion, therefore expends the time untill detection, the yarn of waste
Increase or the joint time is elongated.
For the point, in the structure of present embodiment, the position of test section 68 is fixed, therefore distribution will not be applied
Burden just can determine that whether the seizure of yarn 14 succeeds.Also, examined when suction port 33 is located at the catching position time by portion 69
The inside in test tube portion 32 (especially attracting direction upstream side), therefore, compared with the structure of test section 68 is set in axle portion 31, energy
Enough quickly detect the presence or absence of yarn 14.
Also, as shown in fig. 6, it is configured with guide portion 32c in the inside of pipe portion 32 (cylindrical portion 32a).Guide portion 32c is plate
The part of shape, and direction upstream side is being attracted to configure by portion 69 compared to light.Also, guide portion 32c is with relative to cylindrical portion
32a vertical cross-section and be slightly inclined mode (away from the remote side of suction port 33 positioned at attract direction upstream side mode) match somebody with somebody
Put.In addition, guide portion 32c possesses the 1st guide portion 321 and the 2nd guide portion 322.
1st guide portion 321 is arranged on the near its inner edge away from the remote side of suction port 33 (the opposite side that light passes through portion 69).The
1 guide portion 321 pulls the yarn 14 that suction port 33 is attracted to and guided to the 2nd guide portion 322.
2nd guide portion 322 is arranged on away from the near side of suction port 33 (light by portion 69 near).2nd guide portion 322 has
Recess, yarn 14 are guided by the recess of the 2nd guide portion 322.The yarn 14 being attracted to thereby, it is possible to determine suction port 33
Yarn path.Thus, it is possible to improve the accuracy of detection of yarn 14.
In addition, when light by portion 69 formed with recess in the case of and in the case where otch does not configure transparent panel,
The position relationship of test section 68 and light by portion 69 is adjusted, test section 68 when 22 yarn is wrapped to cause suction port 33 to catch
At least a portion pass through portion 69 ((a) of reference picture 8) into light.Thereby, it is possible to away from the near location determination yarn of suction port 33
Whether the seizure of line 14 succeeds.Even if, also can be with foot in addition, as described above, in the case where otch is configured with transparent panel etc.
Enough accuracy of detection detection yarns 14.
Secondly, the action of the reeling end 17 when reference picture 7 to Fig. 9 catches the yarn 14 of package 22 to suction port 33 is said
It is bright.In addition, action described below simply one, can also replace the serially or simultaneously multiple processing of carry out that a part is handled.
