In JP-A-124777 (hereinafter referred to as Document 1), the number of winding layers of a wire is obtained from the number of reciprocations of a bobbin or a nozzle for winding out, and based on the number of windings, the number of windings of the winding material is normally set on the bobbin. The standard winding outer diameter when wound and laminated is calculated, the actual coil outer diameter is measured by an outer diameter sensor that detects the outer peripheral position of the wire wound around the bobbin, and the actual coil outer diameter and the standard winding are measured. When the difference between the attached outer diameters becomes larger than a predetermined value, it is determined that the winding disturbance has occurred.

はいえない。According to the conventional method for inspecting winding disturbance, according to Document 1, inspection for winding disturbance is performed after the wire winding process is completed. When the winding disturbance is detected, the product must be discarded. And waste of resources increases, resulting in extremely low productivity. Further, in Reference 2, every time winding of one layer is completed, the layer is inspected for turbulence.
Therefore, according to this prior art, when winding disturbance is detected, 1
The entire layer must be unwound, and the productivity is not good.

発生する。In particular, as the winding method, the winding end is gradually advanced from one end in the axial direction of the bobbin shaft to the other end, and the winding number is increased and decreased from the one end to the other end. When the oblique winding is performed in a stepwise manner, the end position of the reciprocating motion forming the winding end changes every one reciprocation, so that winding disturbance is likely to occur near the end position. Further, in the winding inspection method described in Document 1, when the number of layers is large or when a wire having a small wire diameter is wound, there arises a problem that required detection accuracy cannot be satisfied.

An object of the present invention is to provide a winding device and a winding inspection method capable of detecting winding disturbance during a wire winding process.

Is extracted optically, and based on this information, the turbulence of the wire is inspected. In this way, instead of performing a winding disturbance inspection after the wire winding is completed, the winding disturbance inspection process is performed at the same time as the winding process, thereby improving productivity and detecting winding disturbance during winding. Then, the winding can be completed immediately, so that the waste of the wire can be reduced.

Detection accuracy can be improved. That is, when detecting the presence or absence of a wire near the winding end, even a slight winding disturbance can be reliably detected.

For example, if the wire is present at a predetermined portion of the winding advancing end, that is, at a portion adjacent to the advancing side of the turn immediately before the wound wire, the winding is not disturbed. It can be determined that it has occurred. Alternatively, if the wire is wound at a position a predetermined distance away from the winding advancing end toward the axially advancing side, it is determined that a turbulence has occurred. Otherwise, it can be determined that the turbulence does not exist. .

ない。In a preferred embodiment, the irradiation beam is applied to a position 50 to 1200 μm away from the winding end in the axial direction. In other words, the wire rod presence information at a position 50 to 1200 μm away from the winding advance end toward the axial advance side is optically detected. In a normal small coil having a wire diameter of about 30 to 600 μm, when winding disorder occurs, the wire is moved from the winding advance end to the axial advance side by 50 to 1200 μm.
Since the position is shifted by m, the winding disturbance can be accurately determined. In addition, when judging the wire rod deviating from the winding advancing end, when optically examining a position less than 50 μm on the axially advancing side from the winding advancing end, it is not easy to determine whether the winding is disordered, On the other hand, when optically examining a position at a distance of 1200 μm or more, it is difficult to detect a wire even if a turbulence has occurred, so that it is not easy to detect the turbulence.

ことがない。In a preferred embodiment, when it is determined that the turbulence has occurred a predetermined number of times consecutively, preferably four times or more, the turbulence is finally determined. In this way, if the wire rod temporarily shifts by a predetermined distance from the winding advance end to the axial advance side for some reason and then returns to the normal winding advance end, it is erroneously regarded as a winding disorder. There is no detection.

Therefore, it is possible to inspect whether or not the wire is wound at an appropriate position during the wire winding process. This mode of detecting the presence or absence of a wire at a position separated by a predetermined distance from the winding progress end is particularly effective when a certain degree of turbulence is allowed.

び方向の切換え移動パターンと同じにする必要はない。The inspection apparatus of the present embodiment includes an inspection controller 19 as a judging means for judging the output 16a of the light receiver 16. The inspection controller 19 inputs an output 19 a indicating the presence or absence of the wire 11 at the winding progress end to the servo controller 20. The servo system controller 20 outputs signals 1a, 6a and 9a for controlling the servo motors 1, 6 and 9 to the servo motors 1, 6 and 9. As a result, the rotation speed of the main shaft 2 according to the winding method, the winding pitch, and the like, the moving speed of the nozzle unit 4, the switching movement pattern of the direction, and the like are controlled in a predetermined relationship. The switching movement pattern of the moving speed and the direction of the inspection head 12 is the same as the switching movement pattern of the moving speed and the direction of the nozzle unit 4 when a normal annular coil is wound. For coils with oblique windings,
It is not necessary to synchronize the moving speed and direction of the nozzle unit 4 with the moving pattern in synchronization with the winding end of the oblique portion.

The winding end gradually advances from one end side to the other end side of the shaft portion 10a,
This is a winding method in which the outer winding end is stepped toward the upper layer. In this oblique winding, there is no problem if the winding advance end T overlaps the already wound portion as shown by reference numeral T1, and the winding may be performed on the upper layer as it is. However, the sign T
As shown in FIG. 2, the progress of the winding by protruding from the unwound portion of the shaft portion 10 a further deteriorates the later wound state, so that the winding is disturbed.

In FIG. 4, the two-dot chain line indicating the irradiation beam indicates the optical axis. FIG.
The flowchart shown in Fig. 7 shows the flow of the operation of the inspection controller 19, which is started when the bobbin 10 is chucked to the spindle 2, and steps S1 and S2 as initial settings are executed. In S1, a winding method (in this case, oblique winding) is set in S1, and in step S2, the moving speed and moving pattern of the nozzle section 4a, the rotating speed of the main shaft 2, the irradiation beam scanning position, the moving speed and moving pattern, and the like are set. Set. In the case of oblique winding, the movement pattern of the nozzle portion 4a is a pattern in which the reciprocating stroke gradually increases from one end to the other end of the shaft portion 10a. The moving speed and the moving pattern of the inspection head 12 do not need to follow the reciprocating movement of the nozzle portion 4a, but only the movement to the other end at a low speed in accordance with the speed at which the oblique winding end spreads to the other end. Thus, the irradiation beam from the probe unit 14 scans the winding end T of the wire 11 wound around the shaft 10a.
These initial settings are set from the inspection controller 19 to the servo controller 20.

9 is a process for taking in the output 16a from the light receiver 16.
In step S6, the level of the taken output 16a is determined. 4, the level of the output 16a is higher than the reference levels G1 and G2 as shown in FIGS. 5 and 6, depending on whether or not the wire 11 is present at the winding end T as shown in FIG. , Or the reference levels G1 and G2. The level change of the output 16a is illustrated by the difference in reflectance between the surface of the wire 11 and the surface of the shaft 10a when the irradiation beam is obliquely incident as in the embodiment and when the wire 11 is not at the winding advance end T. 5 or FIG. When the reflectance of the surface of the wire 11 is smaller than the reflectance of the surface of the shaft 10a,
As shown in FIG. 5, the turbulence changes G1 in the upward direction (large level). When the reflectivity of the surface of the wire 11 is larger than the reflectivity of the surface of the shaft 10a, as shown in FIG.
2 downward (small level). Assuming that the surface of the shaft portion 10a is covered with an insulating film, the reflectivity is higher than the surface of the insulating material of the wire 11 and the scattered portion becomes a reflected beam, which protrudes upward as shown in FIG.

If the wire 11 is located at the normal winding advancing end T as shown in FIG. 4A, most of the reflected beam will be a component reflected from the wire surface, and no level change will occur in the output 16a. When the wire 11 is wound at the position shown in FIG. 4B, the reflected beam is deflected to the opposite side of the irradiation beam as shown by LB, and the component returning to the probe unit 14 as the reflected beam is reduced (the waveform in FIG. 6).

At this time, the main reflected beam has more scattered LC components than in the case of B, and the output 16a shows an R waveform at a lower level than the Q waveform. Inspection controller 1
9 determines this level change as a turbulence. If it is determined in step S6 that there is no winding disturbance (Y), the inspection controller 19 determines whether or not it is the winding end. If it is not the winding end (N), the process returns to step S4, and if it is the winding end (Y). Ends the winding step of one coil (S8).

In this case, an alarm can be issued, another correction program can be automatically executed, or the turbulence can be corrected manually. As another example, the irradiation beam may be incident on the shaft 10a so as to intersect the shaft 10a at right angles. In the output 16a obtained in this case, when a winding disturbance is detected, a level change protruding in the positive direction shown in FIG. 5 appears.

を特徴とするものである。The difference between the case where the irradiation beam is incident on the shaft portion 10a so as to intersect at a right angle and the case where the irradiation beam is obliquely incident as in the present embodiment is that, in the present embodiment, a wire having a large reflectivity and a shaft having a small axis are used. And can be detected even if the reflectance of the surface of the shaft portion is larger than that in the former case. (Second Embodiment) In the first embodiment, the turbulence of the winding is detected by irradiating the irradiation beam to the winding advancing end T of the winding. However, in the second embodiment, Irradiation is performed at a position separated by a predetermined distance in the traveling direction of the winding.

うになっている。The second embodiment will be described with reference to FIG. As shown in FIG. 7, the irradiation beam BE from a light source (not shown) is a red LED light,
A portion separated by about 1000 μm is always irradiated on the bobbin 10 in the vertical direction. Therefore, the inspection head 12 that emits the irradiation beam BE can move in the horizontal direction along with the horizontal movement of the nozzle unit (not shown).

て、線材の巻き乱れを検出することができる。With the above-described configuration, the bobbin 10 is irradiated with the irradiation beam BE when the wire rod 11 is in a normal state in which the winding disturbance does not occur. However, when winding disturbance occurs, the irradiation beam BE irradiates the wire 11. At this time, the light quantity of the reflected light when irradiating the winding 11 and the light quantity of the reflected light when irradiating the bobbin 10 are different as shown schematically in the circle A and the circle B in FIG. Assuming that the amount of reflected light when irradiating the winding 11 is about 22 mV, the amount of reflected light when irradiating the bobbin 10 is scattered as shown in the B circle, and the amount of light at this time is about 20 mV. Since the amount of light when irradiating the winding 11 is larger, by detecting the difference in the amount of light, the winding disturbance of the wire can be detected.

As compared with the second embodiment, the irradiation beam BE is further supplied to the bobbin 10.
Irradiation is performed at an angle θ of 20 ° with respect to the perpendicular direction of the axial direction. In this case, the inspection head 12 is divided into a light source unit 12A and a light receiving unit 12B.

However, as shown in FIG. 10, when the irradiation beam is irradiated obliquely, the reflected light from the bobbin 10 is not detected.

射ビームによる反射光は検出することができない。Therefore, the amount of reflected light (approximately 22 mV) when irradiating the winding 11 is irradiated with the irradiation beam more vertically than the amount of reflected light (approximately 16 mV) when irradiating the bobbin 10. Since the difference is much larger than the case, the difference between the light amounts can be increased, and the winding disturbance of the wire can be detected with higher accuracy. Further, in the third embodiment, since the irradiation beam is irradiated obliquely, the reflected light is detected by the regular reflection of the irradiation beam at the position of the wire parallel to the winding direction of the wire. can do. On the other hand, when the irradiation beam is applied to the wire portion existing between the winding end and the end of the winding disorder portion, the wire existing between the winding end and the end of the winding disorder portion becomes , Not parallel to the winding direction. Therefore, light reflected by the irradiation beam cannot be detected.

Can be detected. In the third embodiment, the irradiation angle θ of the irradiation beam is set to 20 °. However, as shown in FIG. 11, if the irradiation angle θ is 5 ° or more, the amount of light reflected from the bobbin 10 can be reduced. Difference from the reflected light from the light source can be increased.

なしと判定してステップＳ９に進む。However, if the angle is set to 85 ° or less, there is a problem that it is impossible to detect the turbulence of the wire rod with the irradiation beam. For this reason, in the third embodiment, it is preferable that the irradiation angle of the irradiation beam is inclined within a range of 5 to 85 degrees from the direction perpendicular to the axial direction of the bobbin. (Fourth Embodiment) In the fourth embodiment, when performing oblique winding, an offset corresponding to the movement of the nozzle from the winding nozzle by oblique winding (width of oblique winding portion (length in the bobbin axial direction)). The sensor is mounted integrally with the nozzle at a position separated from the length by the specified width (FIG. 12). Thus, an axis for moving the sensor in synchronization with the movement of the winding end of the oblique winding is required, but it is possible to detect a winding turbulence only with the movement axis of the nozzle. (Fifth Embodiment) In the second embodiment, a predetermined interval (50 to 1200 .mu.m) in the traveling direction from the winding advance end T of the winding.
m, more preferably, 1000 μm), and the presence or absence of the wire 11 was inspected by irradiating it with an irradiation beam. In this embodiment, the inspection is performed at a constant interval (here, 1 mse) in step S5 shown in FIG. It is performed sequentially. In the determination at S6, if all the immediately preceding consecutive inspection results (four times in this case) are all determined to be turbulent (that is, there is a wire), it is finally determined to be turbulent, and the process proceeds to step S9. If not, it is determined that there is no turbulence, and the process proceeds to step S9.

果により初めて巻き乱れと判定することもできる。In this manner, when the wire is temporarily shifted from the winding end by a predetermined distance toward the axially moving side for some reason, and then returns to the normal winding end, the wire is wound. There is no false detection of disturbance. Note that such a shift of the wire 11 toward the axially advancing side may occur, for example, when the wire slides on the shaft portion or is pushed out. However, in many cases, such a deviation returns to a normal position, that is, a winding progress end due to the tension of the wire 11, and the winding disturbance is eliminated. Therefore, according to this embodiment, it is possible to improve the detection accuracy without erroneously detecting a temporary wire rod displacement. (Modification) In the fifth embodiment, a predetermined interval (50 to 1200 μm) is set in the traveling direction from the winding advance end T of the winding.
m, more preferably 100 to 1000 μm), the winding disturbance is determined for the first time based on the result of the presence of the wire rod which is temporally continuous a plurality of times at positions separated from each other. It is also possible to determine that the winding is turbulent only on the basis of the result of the continuous absence of the wire plural times.

に好ましい。Further, the inspection at the winding advance end and the inspection at a position away from the winding advance end by a predetermined distance from the winding advance end may be performed at the same time. The wire position can also be monitored.
The time from the occurrence of a temporary displacement of the wire in the axial direction to the elimination thereof is usually 144 times the rotation angle of the bobbin.
At 0 degree, that is, in this embodiment, since the bobbin occurs during four rotations, at least one test result among the test results obtained by judging data sequentially sampled at a constant interval from the reflected light, and this test result In the case where all the inspection results including the inspection result obtained at an angle position exceeding 1440 degrees in the rotation angle of the bobbin with respect to the obtained bobbin angle position show the winding disorder, Is preferable in order to prevent the above-mentioned temporary wire rod displacement (immediately after the displacement is eliminated) from being erroneously determined as a winding disturbance.
