Abstract

PROBLEM TO BE SOLVED: To layer a winding layer without leaving any aligning defect so as to prevent accumulation of a winding error due to a aligning defect when winding is continued by detecting whether a aligning defect such as a jump of a line or an overlap of a wire rod body is caused or not in at least every winding layer. SOLUTION: In the subject controller, a frequency of sudden change in a positional signal Sp from a laser type wire rod body position detector, which detects the traverse directional position of a wire rod body between a wire rod type body feeder and a winding drum, is counted by means of a counter 48 in every each winding layer. Then, this counting value Tp2 is compared with a counting value (reference counting value) Tp1 of the frequency of the sudden change in the traverse directional position signal Sp in the previous winding layer by means of a determination circuit 50, and if these counting values are different from each other, it is determined that a aligning defect is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for aligning and winding a wire such as an electric wire, an optical fiber, a metal or plastic tube, and a wire such as a rectangular metal wire. In particular, it is determined that misalignment has occurred due to the striated body being dashed (gap winding) or lap winding (riding winding) in each winding layer, and the winding of the striated body is corrected or wound. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a striated body aligning and winding control device capable of stopping take-up.

2. Description of the Related Art In order to align and wind a wire on a winding drum, a wire feeder for supplying the wire to the winding drum is generally translated relative to the rotation axis of the winding drum. The wire is traversed at a pitch corresponding to its diameter (linear body) or width (strip), but in this case, the filament is wound on a winding drum. It is supplied at a predetermined delay angle so as to be pressed against the side surface of the attached turn portion and wound in a line.

When the filament feeder moves relatively parallel to the axis of rotation of the winding drum, the traverser including the filament feeder moves the filament laterally every one revolution of the winding drum. Direction, but the pitch of the traverse of the striated body is shifted for some reason and one row of winding layers flies, leaving a gap between turns, or conversely, one row of one winding layer. Sometimes the striatum climbs on top of it, causing misalignment, but if you overlook this and continue to wind it up, misalignment will accumulate and eventually the striatum's winding appearance will collapse,
If a misalignment of the striatum occurs, it must be corrected or the winding stopped. This displacement of the lateral movement of the striated body can be caused by fluctuations in the feed speed of the striated body lateral feeding means, in addition to the properties of the striated body itself, such as twisting, curling, and deformation of the striated body. It may be caused by a mechanical cause.

[0004] Generally, in order to align and wind the filament while traversing it at a predetermined pitch on the winding drum, the filament is positioned between the filament feeder and the winding point of the winding drum. The feed angle is detected, and when the feed angle of the striatum changes beyond a normal range, the traverse speed (traverse speed) of the striatum feeder is controlled so as to correct the change. (For example, JP-A-51-92078, Japanese Utility Model Application Laid-Open No.
No. 06561, JP-A-62-240265 and JP-A-1-203174).

Among these prior arts, Japanese Patent Application Laid-Open No.
No. 2078 and Japanese Utility Model Application Laid-Open No. 61-206562 disclose a linear body winding retrieving control device, in which a change in the supply angle of the linear body to the winding drum exceeds a predetermined allowable range. The filament feeder is moved to a predetermined position with respect to the winding drum so as to return the supply angle of the body to a predetermined range, and the operation of following the filament feeder is performed by the winding drum. Irrespective of the rotation of the wire, it is performed in accordance with the cumulative value of the change in the supply angle of the wire with respect to the winding drum. The winding is continued without being performed. Therefore, for example, even if the striatum is wound with a gap, if the striatum is small, it is not determined that the wire is not aligned properly, the striatum is continuously wound, and the accumulated value of the gap increases. When the supply angle becomes larger than the initial value, the misalignment is determined only when the supply angle is larger than the initial value. Therefore, the misalignment may be accumulated to such an extent that the misalignment cannot be corrected. When the change is large enough to deviate from the range, the filament feeder is only fast-forwarded to absorb this large change. Since the continuous operation is performed, there is a possibility that the striated body is wound up particularly on the winding layer having the misalignment, which may promote the misalignment. This phenomenon similarly occurs when the striatum causes misalignment due to climbing.

Further, the angle detector described in Japanese Utility Model Laid-Open No. 61-206561 is composed of a pair of detection switches arranged at both sides of the traverse table with an angular displacement of the traverse table. Since it is not possible to detect a small angular displacement, it is not possible to detect misalignment due to running up of the striatum. For this reason, there is a possibility that it is determined that the striated body is performing the predetermined alignment winding, and the winding is continued, thereby promoting misalignment.

Further, the angle detectors described in JP-A-62-240265 and JP-A-1-203174 are composed of a visual sensor such as a TV camera. Since the supply state of the body is read as image information, this image information must be processed and the supply angle of the striatum must be detected from the content of this image information, so that complicated image processing is required.

It is an object of the present invention to provide an alignment and winding control device for a striated body in which winding is continued by winding up a winding layer while remaining, so that winding errors due to poor alignment are not accumulated.

It is an object of the present invention to provide an alignment and winding control device for a striated body in which winding errors due to poor alignment are not accumulated.

In the first aspect, it is preferable that the misalignment judging means includes a storage circuit for sequentially storing a count value of the number of abrupt position signal changes of each winding layer. When the count value of the number of abrupt changes in the position signal of each winding layer is stored, the storage circuit outputs the previous count value to the comparator and clears the previous count value.

According to a second aspect of the present invention, there is provided a winding drum for winding a filament, and a filament feeder for supplying the filament to the winding drum.

When the count value is different, it is determined that misalignment has occurred, or the abrupt change in the position signal in the transverse feed direction of the striated body is determined according to the rotation speed of the winding drum for each rotation of the winding drum. It is determined whether or not it is in the normal range, and it is determined that misalignment has occurred when no abrupt change of the position signal in the normal range has occurred, so each winding layer or each turn Misalignment can be detected.

Therefore, irrespective of the rotation of the winding drum, when the accumulated change amount of the supply angle of the filament goes out of the predetermined range, the supply angle of the filament is returned to the predetermined range. As in the case of controlling the traverse speed, the winding of the striatum is not continued while overlooking the misalignment,
Therefore, winding is not performed while accumulating winding errors due to misalignment, and a defective winding shape can be prevented.

The normal range of the abrupt change in the position signal of the filament is obtained by calculating according to the rotation speed of the winding drum. Can be determined with certainty.

When the numerical values are different, it is determined that misalignment has occurred, and a sudden change in the position signal in the transverse feed direction of the striated body is determined according to the number of rotations of the winding drum every time the winding drum rotates. Judgment whether or not the position is within the range, judge that misalignment has occurred when no abrupt change of the position signal within the normal range has occurred, and misalignment only when receiving both of these judgment signals When a signal is generated, it is necessary to double-check the winding state of the striatum. Since it is, compared to the case of judging only one judgment, more securely detect the misalignment of the striatum. In this case, the first misalignment is determined for each winding layer of the striatum, and the second misalignment is determined for each turn of the striatum. Needs to be held until the end of one winding layer that gives the former determination result.

As shown in FIG. 3, the traverse drive control circuit 42 receives a pulse signal from a pulse generator 54 for detecting the rotation speed of the winding drum 24 and a pulse generator 56 for detecting the rotation speed of the traverse drive motor 36. Receiving P ₂₄ and P ₃₆ , respectively, it generates a drive signal So for driving the traverse drive motor 36.

As shown in FIGS. 1 and 3, the traverse drive control circuit 42, when the striatum lateral feed means 30 and the striatum feeder 18 reach the reversing position, detects the reversing position from the reversing position detecting means 58. It receives the inversion command Sl or Sr. As shown in FIG. 1, the inversion position detecting means 58 includes a reflector 64 attached to a bracket 62 supporting a laser type position detector 60, which will be described later, and a reflection member at a position where the filament feeder 18 is to be inverted.

In the illustrated embodiment, the striatum position detecting means 44
As shown in FIGS. 1 and 2, the linear diameter or the width of the striated body 1 is radiated by irradiating a laser beam to the striated body 1 and supported by a bracket 62 extending from the casing 28 of the striated body supply device 18. It consists of a laser position detector 60 for detection.

The laser type position detector 60 is shown in FIGS.
As shown in FIG. 7, a light projector 68 arranged so as to scan the striated body 1 with a parallel laser beam interposed across the running path of the striated body 1 and receives a change in light (brightness or darkness) from the illuminated light source 68 Light receiver 68 'for generating a signal corresponding to a change in light
And The light receiver 68 ′ includes a photoelectric light receiving element that generates an electric signal that changes based on a change in light from the light emitter 68.

As described above, the striated body lateral feeding means 30 and the striated body feeder 18 move laterally in accordance with the traverse pitch Pt for each rotation of the winding drum 14, while the winding position of the striated body 1 Pw does not change laterally during one rotation of the take-up drum 14 until the transition from one turn to the next. Accordingly, when the filament 1 is wound on the winding drum 14 for one turn, as shown in FIG.
In the laser type position detector 60, the position gradually changes in a direction parallel to the axial direction of the winding drum 14 during most of the turn from the start of one turn (during a normal winding portion of one turn). However, during a slight rotation angle of the winding drum 14 which shifts toward the beginning of the next turn near the end of one turn, the winding position Pw of the filament 1 is set at the axis of the winding drum 14. Since the direction changes rapidly, striatum 1
Also, the position rapidly changes in the laser position detector 60 in a direction parallel to the axial direction of the winding drum 14.

Accordingly, the output of the laser type position detector 60 between the winding position Pw of the filament 1 and the filament feeder 18 indicates that the output of the laser type position detector 60 is normal while the filament 1 is normally wound. , FIG.
As shown in (A), it changes in a sawtooth shape. In the waveform of FIG. 5 (A), the length α of the horizontal axis is a winding in which the position of the striatum 1 rapidly changes by the traverse pitch Pt toward the beginning of the next turn as the striatum 1 approaches the end of one turn. The length of the horizontal axis of the rotation angle of the take-up drum 14 is shown. The length of the horizontal axis of the angle portion α is abruptly increased in the lateral direction by the lateral movement of the linear position detector 60 within the laser type position detector 60. Corresponds to the drum angle Aα in FIG. In the waveform of FIG. 5A, the length β of the horizontal axis is
The remaining rotation angle portion during one rotation of the winding drum 14 is shown, and the horizontal axis length of this angle β indicates that the striatum 1 is in the laser type position detector 60 in the laser type position detector 60. This corresponds to the drum angle Aβ in FIG. 4 in which the position is gradually changed in the lateral direction by the lateral movement of the laser position detector 60.

When the striated body 1 is wound and wound on the winding drum 14 in a row, or is wound by overlapping winding, the output Sp of the laser type position detector 60 becomes as shown in FIG. It appears with the waveform shown in FIG. In the waveform of FIG. 5B, a waveform portion indicated by a symbol Wg indicates a state where the striatum 1 moves laterally from the end of one turn toward the beginning of the next turn (the winding drum).

The case where the position of the filament 1 hardly changes at a pitch that does not reach the traverse pitch Pt corresponding to the wire diameter or width of the filament 1 (lap winding) is shown.

As shown in the figure, when there is a line jump exceeding the traverse pitch, the number of turns (traverse number) of one winding layer becomes four, and only four pulse signals Pp indicating the number of traverses are generated. Also, for example, as shown in FIG. 5C, when there is one lap winding, the number of turns (traverse number) of one winding layer is six turns, and the six pulse signals Sp indicating the number of traverses are provided. Occurs. These pulse signals Pp are output to the misalignment determination unit 5.

Further includes a storage circuit 72 for storing the count value of the pulse signal Pp from the counter 48 for each winding layer, and the storage circuit 72 stores the count value (reference meter) previously stored for each winding layer. The value Tp1) is sent to the determination circuit 50, and the next count value (current count value Tp2) is received from the counter 48 to rewrite the count value of the pulse signal Pp.

As shown in FIG. 3, misalignment judging means 52
Operates the counter 48 so as to count the abrupt change of the position signal of the striatum 1 for each winding layer of the striatum 1, rewrites the storage circuit 72, and sets the In order to compare the count value between the layer and the previous winding layer, the inverted signals S1 and Sr from the inversion detecting means 58 are received. That is, these inverted signals Sl and Sr are output from the counter 48 and the storage circuit 7.

As shown in FIG. 3, the filament winding and winding control device 10 of the present invention comprises a winding drum drive motor 24 of the filament winding machine 12 and a traverser drive motor of the filament lateral feeding means 30. And a drive stop circuit 74 for stopping the drive with the drive 36.
A drive stop command Ss is generated when the misalignment determination signal Sb is received from the determination circuit 50, and the motor drive control circuit 76 of the winding drum drive motor 24 and the striatum lateral feed means 3
Motor drive control circuit 4 for traverser drive motor 36 of 0
2 is supplied with the drive stop command Ss. As will be described later in connection with the description of the operation, misalignment is caused by the fact that the filament 1 is wound around with one turn gap to cause a turn jump (row jump) or that the filament 1 is over the previous turn. When the winding is overtaken and the winding is overlooked, if the winding is continued, the winding state of the striatum becomes abnormal. Therefore, when the misalignment determination signal Sb is generated, It is required to stop the strip winding machine 12 and correct the misalignment as soon as possible.

Next, the operation of the control device 10 for aligning and winding the striated body of the present invention will be described with reference to the flowchart of FIG. 6 based on the embodiment of FIGS. As shown in FIGS. 1 and 2, the filament 1 is wound on a winding drum 14 on a filament winding machine 12 via a filament feeder 18. Reference numeral 30 designates a predetermined traverse pitch P for each rotation of the winding drum 14 by rotating the filament feeder 18.
The traversal body 1 moves laterally at t and relatively traverses to the right or left every time the turn increases on the winding drum 14. FIGS. 1 and 4 show that the filament 1 is traversed rightward from the right flange 15A of the winding drum 14 to the left flange 15B.

Also, as shown in FIGS. 1 and 4, the striated body 1 is wound on the winding drum 14 so as to be closely adjacent to the previous turn (one winding part of the striated body). The wire body 1 is wound so as to be shifted in the delay direction with respect to the traversing direction.

The traverse drive control circuit 42 corresponds to one rotation of the winding drum 14 from the pulse generator 54 for detecting the rotation of the winding motor 24 based on the traverse pitch Pt (see FIG. 3) inputted in advance. Each time a pulse is received, the traverse drive motor 36 is driven so that the striatum lateral feed means 30 moves rightward at the traverse pitch Pt. Therefore, the filament feeder 18 supplies the filament 1 to the winding position Pw such that the filament 1 maintains a proper delay in the delay direction with respect to the winding position Pw. Thus, the filament 1 is normally wound around the winding drum 14 in a good alignment state. The traverse drive motor 3
The pulse generator 56 for detecting the rotation speed of the traverse drive control circuit 4
2 to determine whether the traverse drive motor 36 has rotated properly.

The striatum supply 18 moves rightward from the position shown in FIG. 1 and the reflector 64 of the reversal position detecting means 58 reaches the position to be reversed leftward facing the reversing position detecting light emitting / receiving device 66. Then, since the light emitter / receiver 66 supplies the reversal command S1 to the traverse drive control circuit 42, the traverse drive control circuit 42 drives the traverse drive motor 36 in the reverse direction, and Lateral feeding means 30
Move to the left in the opposite direction.

As described above, at the time of this reversal, the deviation in the delay direction with respect to the winding position of the filament 1 is reversed. Therefore, at the time of the reversal, it is necessary to maintain this deviation at once. , The traverser amount at the time of reversal becomes twice as large as that in the normal case.

While the filament 1 is being wound on the winding drum 14, the filament 1 is, as described above, between the winding drum 14 and the filament feeder 18. In the body position detecting means 44, it is displaced in the direction opposite to the lateral feeding direction of the striatum 1 and the laser type position detector 60 of the striated body position detecting means 44 is shown in FIGS. 5 (A) to 5 (C). Thus, the position signal Sp of the filament 1 that changes according to the rotation angle of the winding drum 14 is detected (see block 1 in FIG. 6).

This position signal Sp is supplied to the misalignment determination means 5.
The second position change detector 46 converts the position signal Sp into a pulse signal Pp for detecting only a sudden change (FIG. 6).
Block 2 and waveforms (a) and (b) in FIG. 7). This pulse signal Pp indicates that the position of the striatum 1 has changed abruptly, regardless of whether the striatum 1 is wound normally or not. Is a traverse signal indicating that the traverse has been traversed in the axial direction of the winding drum 14 near the end of the period.

This pulse signal Pp is input to the counter 48 of the misalignment judging means 52 and counted until the inverted signal Sl or Sr is input from the inverted position detecting means 58 (blocks 3 and 7 in FIG. 6). Waveform (c)). Since the counter 48 counts the pulse signal Pp from the time when the striatum 1 is inverted to start winding and the next inverted signal is output, the count values Tp1 and Tp2 −−−− are: Striatum 1
The number of times (the number of traverses or the number of turns of one winding layer) of the abrupt position change of the filament 1 of one winding layer is shown. In addition, Tp1 and Tp2----sequentially indicate the count value of the pulse signal of each winding layer.

When the inverted signal Sl or Sr is input to the misalignment judging means 52 (waveform (c) in FIG. 7), the counter 48 is reset, and the judging circuit 50 outputs the last counted value (current value). (Count value) Tp2 is compared with the previously counted reference count value Tp1 (see block 4 in FIG. 6) .If the reference count value Tp1 and the current count value Tp2 match, the number of traverse times is calculated. Alternatively, since there is no change in the number of turns, it is determined that the alignment is good (see Y of block 4 in FIG. 6), and the winding to the next winding layer is continued as it is, and the flowchart is the first stage (block in FIG. 6). Returning to 1), the same operation as above is repeated.

If the count values Tp1 and Tp2 do not match (N in block 4 in FIG. 6), the number of traverses or the number of turns in the upper and lower winding layers has changed, so that it is determined that the alignment is poor. A misalignment determination signal Sb is generated (see block 6 in FIG. 6 and (d) in FIG. 7).

When drive stop circuit 74 receives this alignment failure determination signal Sb, drive stop circuit 74, as shown in FIG.
Supplies the drive stop command Ss to the traverse drive control circuit 42 and the winding drive control circuit 76,
2 and the striatum lateral feed means 30 are immediately stopped.

After the winding operation of the striated body 1 is stopped, the operator can unwind the striated body 1 of the winding layer in which the misalignment has occurred, and correct the misalignment.
If it is difficult to correct the misalignment due to a long unwinding amount, the winding operation is stopped, the winding drum 14 is replaced, and the filament 1 is wound on a new winding drum 14. The winding work of. In any case, after the misalignment of the striated body 1 occurs, the winding operation is continued and the misalignment is accumulated to make it difficult to correct, or the unnecessary winding operation after the misalignment is continued. Disappears.

If there is a line jump in the striatum 1, the abrupt change in the position of the striatum 1 is larger than the usual large position change near the end of one turn, and the pulse signal Pp is larger. If there is a lap winding on 1, the abrupt change in the position of the striatum 1 is smaller than the usual large change in position near the end of one turn, but this small change is a slow change before the end of one turn. It is larger than the position change (waveform W in FIG. 5C).
o), and can be reliably distinguished from other normal position changes.

To describe a specific embodiment of the present invention, assuming that the outer diameter of the filament 1 is 10 mm, the winding drum 1
4 also has a traverse pitch of 10 mm per rotation, and the striatum feeder 18 has a traverse pitch of 10 mm.
Traverse pitch Pt = 10 mm in the laser type striated body position detector 60
, Gradually changes in the direction opposite to the traverse direction (traverse direction), and near the end of one turn, rapidly changes in the traverse direction corresponding to the traverse pitch Pt = 10 mm. For example, from the striatum supply device 18 to the winding position P
Assuming that the distance to the w is 1000 mm and the distance from the wire feeder 18 to the striatum position detector 60 is 200 mm, when the striatum 1 changes position by 10 mm at the winding position Pw, the striatum 1 The position of the body position detector 60 changes by 2 mm. Accordingly, the position signal Sp of the striatum position detector 60 is
Is 2 if normal traverse operation is being performed.
It changes in accordance with a sudden change in position of mm, and if there is a line jump, a position change considerably larger than 2 mm, for example, if there is a one-turn line jump, abruptly changes in accordance with a position change of 4 mm. If there is a lap winding, the position change is considerably smaller than 2 mm. For example, if there is a lap winding diagonally above the previous turn by deviating in the transverse direction, 1 mm
Smaller and sharper changes.

Assuming that the number of turns when one winding layer is normally wound is 40, for example, FIG.
As shown in the waveform Wg of (B), if there is a line jump (gap) exceeding the traverse pitch Pt in the middle of the turn,
The number of turns (traverse number) of one winding layer is 39 turns, and only 39 pulse signals Pp indicating the number of traverses are generated. For example, as shown in FIG. If there is, the number of turns (traverse number) of one winding layer becomes 41 turns, and 41 pulse signals Sp indicating the number of traverses are generated. Therefore, Tp1 = 40 and Tp2 = 39 or 4
When it is 1, skipping or overlapping winding is determined.

In the above-described embodiment, the misalignment judging means 52 determines the number of abrupt position changes (current count value Tp2) of the filament 1 of each winding layer by the number of filaments 1 of the preceding winding layer. The presence / absence of misalignment is determined by comparing the number of abrupt position changes (reference count value Tp1). Unless the misalignment occurs, the number of abrupt position changes of the filament 1 of each winding layer is determined. Is not limited to the number of times of abrupt position change of the wire body 1 of the immediately preceding winding layer, as compared with the sudden position change of the wire body 1 of any earlier winding layer. Is also good. However,
The number of abrupt position changes of the wire body 1 of the winding layer depends on the misalignment of the first winding layer wound first on the body of the winding drum 14, if the winding layer on the winding layer 14 has misalignment. The number of abrupt position changes of the body 1 matches the number of abrupt position changes of the striatum 1 of the first winding layer, and despite the misalignment,
Since it is determined that there is no misalignment, only the misalignment of the first winding layer can be judged by the operator without regard, or the first winding layer can be placed on the body of the winding drum 14 on which the first winding layer is to be wound. It is required that the first winding layer is always wound without causing misalignment by providing a winding groove in which each turn portion of the winding layer falls. Further, the number of turns (the number of turns) of the position of the winding layer, which is the reference count value, is determined by the width of the body of the winding drum 14 (length in the axial direction) and the pitch of the filament 1 (in the case of dense winding). (Corresponding to the outer diameter or width dimension of the striatum 1), and the number of turns may be input to the determination circuit 50 as the reference count value Tp1 of the number of position changes.

In the above embodiment, the storage circuit 74
Is always rewritten, as long as there is no change in the count value Tp2 of the number of abrupt position changes of the striatum 1 of each winding layer, since the winding layers are aligned and wound, The reference count value Tp1 of one winding layer that is surely aligned and wound is kept stored, and this reference count value Tp1 is used as the number of times of abrupt position change of the filament 1 that is sequentially counted in each winding layer. You may compare with the count value Tp2.

FIG. 8 shows another embodiment of the control device 10 for arranging and winding the striated body of the present invention. In this embodiment, too, the striated winding machine 12 has the structure shown in FIGS. The form shown in FIG. 1 to 3, the traverse drive motor 36 of the traverse feeder 30 (see FIGS. 1 and 2) is provided. A traverse drive control circuit 42 for controlling the driving, and a winding position P of the striatum 1
and a striated body position detecting means 4 disposed between the w and the striated body feeder 18 to detect the position of the striated body 1 in the relative transverse direction.
4 and the position signal Sp from the striatum position detecting means 44.
And a drive stop circuit 74 for stopping the operation of the apparatus in accordance with the misalignment determination signal Sb from the misalignment determination means 152.

The traverse drive control circuit 42, the striated body position detecting means 44, and the drive stop circuit 74 are completely the same as those in the embodiment shown in FIGS. As in the embodiment of FIGS. 1 to 3, when the drive stop circuit 74 receives the misalignment signal Sb, the drive stop circuit 74 sends the traverser drive motor 36 and the take-up motor via the traverser drive control circuit 42 and the take-up drive control circuit 76. 24 is stopped.

As shown in FIG. 8, the misalignment judging means 152 has a position change detector 146 for detecting a sudden change in the position signal Sp of the striatum 1 from the striatum position detecting means 44.
It is determined whether or not the rapid change of the position signal from the position change detector 146 is within a normal range (between X and X ') determined according to the rotation speed of the winding drum 14. A sudden change in the position signal in the range
It comprises a judgment circuit 150 for judging that an alignment error has occurred when it has not occurred during rotation.

As in the embodiment shown in FIGS. 1 to 3, when the filament 1 is wound on the winding drum 14 for one turn, as shown in FIG. During the most part from the beginning of one turn (during a normal winding part of one turn), the laser position detector 60 gradually changes in a direction parallel to the axial direction of the winding drum 14, Near the end of one turn and during the slight rotation angle of the winding drum 14, which moves towards the beginning of the next turn,
Since the winding position Pw of the filament 1 rapidly changes in the axial direction of the winding drum 14, the filament 1 also sharply moves in the laser position detector 60 in a direction parallel to the axis of the winding drum 14. Changes to

Accordingly, the output (position signal) Sp of the laser type position detector 60 between the winding position Pw of the filament 1 and the filament feeder 18 indicates that the filament 1 has been wound normally. 5 (A), and when the striated body 1 is hopped and wound on the winding drum 14 or wound up by overlapping winding. The output (position signal) Sp of the laser type position detector 60 appears in the waveforms shown in FIGS. 5B and 5C, which is also the same as the embodiment of FIGS.

As in the embodiment shown in FIG. 3, the position change detector 146 changes the output (position signal) Sp of the laser type position detector 60 of the striatum position detecting means 44 rapidly (the waveform shown in FIG. 5). The signal conversion circuit 170 converts the change in the middle angle α into a pulse signal Pp. During normal winding, when one winding layer has 5 turns, FIG.
As shown in (A), during normal winding,
Each time the striatum 1 suddenly moves laterally toward the next turn near the end of each turn, a predetermined level (between X and X ')
Is generated (see FIG. 10A). Also, as shown by the waveform Wg in FIG.
If there is a row jump exceeding the traverse pitch Pt in the second turn, the sudden change of the position signal Sp due to this row jump is larger than that in the normal lateral movement, and therefore, a pulse signal of level R> X exceeding a predetermined level Ppna occurs (FIG. 10)
(See FIG. 5B.) Further, if there is a lap winding in the second turn as shown by the waveform Wo in FIG. 5C, the rapid change of the position signal Sp due to the lap winding is smaller than that in the normal lateral movement. And generates a pulse signal Ppnb having a level R <X ′ which is lower than a predetermined level (see FIG. 10C).

As shown in FIG. 8, the determination circuit 150 determines whether the pulse signal Pp (Ppn, Ppna, Ppnb, etc.) from the signal conversion circuit 170 of the position change detector 146 is between predetermined levels X and X ′ ( It is determined whether or not it is within a normal range, and if it is out of the predetermined level, it is determined that there is a misalignment, and a misalignment determination signal Sb is generated.

As shown in FIG. 8, misalignment determination means 15
2. The winding motor 24 of the winding drum 14 operates so that the determination circuit 150 operates every rotation of the winding drum 14.
A pulse signal P ₂₄ instructing one rotation of the winding motor 24 is received from the pulse generator 54 for detecting the number of rotations.

Next, based on the embodiment of FIG. 8, the operation of the striated body winding and winding control device 10 of the present invention will be described with reference to the flowchart of FIG. The winding state of the striated body 1, the lateral feeding operation, and the reversing operation thereof are the same as those in the embodiment of FIGS.

While the filament 1 is being wound on the winding drum 14, as described above, the filament 1 is connected between the winding drum 14 and the filament feeder 18. In the body position detecting means 44, it is displaced in the direction opposite to the lateral feeding direction of the striatum 1 and the laser type position detector 60 of the striated body position detecting means 44 is shown in FIGS. 5 (A) to 5 (C). Thus, the position signal Sp of the striatum 1 that changes according to the rotation angle of the winding drum 14 is detected (see block 1 in FIG. 9).

The position signal Sp is supplied to the misalignment judging means 1
The position change detector 146 converts the position signal Sp into a pulse signal Pp for detecting only a sudden change (the block 2 in FIG. 9 and the waveforms (A) and (B) in FIG. 10).
(C)). This pulse signal Pp indicates that the position of the striatum 1 has changed abruptly, regardless of whether the striatum 1 is wound normally or not. Is a traverse signal indicating that the traverse has been traversed in the axial direction of the winding drum 14 near the end of the period.

This pulse signal Pp is input to the judgment circuit 150 of the misalignment judging means 152 (see block 4 in FIG. 9). The determination circuit 150 determines the normal range (X and X ′) in which the pulse signal Pp is input in advance for each pulse signal (pulse signal instructing one rotation) P ₂₄ supplied for each rotation of the winding motor 24. (See block 3 in FIG. 9)
Is determined (see block 4 in FIG. 9).

If the level of the pulse signal Pp is
If it is between the normal ranges X and X 'as indicated by Ppn in (A), it is determined that the alignment is good (see Y in block 4 in FIG. 9), and the winding is continued as it is, and the flowchart is repeated. Returns to the initial stage (block 1 in FIG. 9) and repeats the same operation as described above.

Also, if the level of the pulse signal Pp is
As shown by Ppna or Ppnb of 0 (B) (C),
If it is not between the normal ranges X and X '(N in block 4 in FIG. 9), it is determined that there is a skip or overlap winding, it is determined that the alignment is defective, and an alignment error determination signal Sb is generated (FIG. 9). 9, block 5). Referring to FIG. 12, there is shown an example in which there is a line jump in the fourth turn of one winding layer.

When drive stop circuit 74 receives this alignment failure determination signal Sb, drive stop circuit 74 issues drive stop command S
s is supplied to the traverse drive control circuit 42 and the winding drive control circuit 76, and the winding operation is stopped (see FIG. 8).
Therefore, the filament winding machine 12 and the filament lateral feeding means 30
Can be stopped immediately to prevent the winding from collapsing due to misalignment.

The normal range of the level of the pulse signal Pp (the normal range of a sudden change in the position of the striatum 1 during normal winding) is as shown in FIGS. 11A and 11B. Then, it changes according to the rotation speed of the winding drum 14. This normal range (between X and X ') is input to the determination circuit 150 from the calculation unit 154 which calculates this normal range according to the rotation speed of the winding drum 14, as shown in FIG.

A specific example to which the second embodiment of the present invention is applied will be described. An example corresponding to the second embodiment is also a specific example corresponding to the first embodiment. As in the example, assuming that the outer diameter of the filament 1 and the traverse pitch Pt are 10 mm, the traverse pitch Pt = 1 in the laser type filament position detector 60.
In response to 0 mm, the direction gradually changes in the direction opposite to the traverse direction (traverse direction), and near the end of one turn, this time changes in the traverse direction corresponding to the traverse pitch Pt = 10 mm. Similarly, for example, the striatum feeder 1
The distance from 8 to the winding position Pw is 1000 mm,
Assuming that the distance from the wire feeder 18 to the striated body position detector 60 is 200 mm, the striated body 1 is 10
mm, the striatal position detector 60 changes the position by 2 mm.
Change. Therefore, the position signal of the striatum position detector 60 becomes 2 when a normal traverse operation is performed.
It changes in accordance with a sudden change in position of mm, and if there is a line jump, a position change considerably larger than 2 mm, for example, if there is a one-turn line jump, abruptly changes in accordance with a position change of 4 mm. If there is a lap winding, the position change is considerably smaller than 2 mm. For example, if there is a lap winding diagonally above the previous turn by deviating in the transverse direction, 1 mm
Smaller and sharper changes.

Therefore, for example, as shown by a waveform Wg in FIG. 5B, if there is a line jump (a gap) exceeding the traverse pitch Pt in the middle of the second turn in a certain winding layer,
This changes at a large level in the position signal Sp as shown by the waveform Wg, and the pulse signal Pp is changed to Ppn in FIG.
As shown at a, it has a level above the upper limit X between the normal ranges X and X '. For example, as shown in FIG. 5C, when there is one lap winding, if there is a lap winding that does not reach the traverse pitch Pt in the second turn in a certain winding layer, this is a position signal. Sp changes at a small level as shown by the waveform Wo, and the pulse signal Pp becomes
As shown by Ppnb in FIG. 10C, the level has a level exceeding a lower limit X ′ between the normal ranges X and X ′. Therefore, when a misalignment occurs in a certain turn, the misalignment can be immediately determined in the turn and the misalignment determination signal Sb can be generated.

In the above two embodiments, the winding drum 14 is stopped, and the filament feeder 18 is moved with respect to the winding drum 14 along the rotation axis of the winding drum 14. Although the striated body 1 is relatively traversed with respect to the winding position of the winding drum 14, the striated body supplying device 18 is stationary so as not to move along the rotation axis of the winding drum 14. Then, the winding drum 14 may be laterally moved in parallel to the rotation axis to traverse the filament 1 with respect to the winding position of the winding drum 14. In this embodiment, the striated transverse feed means 30 acts to laterally move the winding drum 14 of the striated winder 12 together with its support means.

FIG. 13 shows still another embodiment of the present invention. The striated body winding control device 10 according to this embodiment is used in the first embodiment shown in FIG. The first misalignment judging means 52 and the second misalignment judging means 152 used in the second embodiment shown in FIG.
And these first and second misalignment determining means 52, 15
Misalignment determination signal from both the 2 Sb _1, when receiving the Sb ₂ and a misalignment signal generating circuit 172 for generating a misalignment signal Sb _12.

Although not shown in detail in the drawings, the first misalignment judging means 52 and the second misalignment judging means 152
Can share the position change detector indicated by reference numeral 46 in FIG. 3 or reference numeral 146 in FIG. 8, and this position detector has a position signal Sp from the common position change detection means 44.
Is supplied.

The misalignment signal generation circuit 172
The first and second misalignment determining means 52 for each winding layer of
Misalignment determination signal Sb ₁ from any or the first and second misalignment determination means 52, 152 when receiving the alignment defect determination signal Sb ₁ or Sb ₂ only from one of the 152,
When Sb ₂ is not received, no misalignment signal Sb ₁₂ is generated, and when the misalignment determination signals Sb ₁ , Sb ₂ are received from both the first and second misalignment judging means 52, 152, alignment is performed. It consists aND circuit for generating a defect signal Sb _12.

[0078] The misalignment signal Sb _12, as shown in FIG. 13, is supplied to the drive stop circuit 74, drive stop circuit 7
4, upon receiving the alignment defect determination signal Sb _12, supplies the drive stop command Ss on the traverse drive control circuit 42 and the take-up drive control circuit 76 stops the winding operation. Therefore, the wire winding machine 12 and the wire traversing means 30 can be immediately stopped to prevent the winding form from being broken due to misalignment.

The misalignment signal generation circuit 172 determines the presence or absence of the misalignment determination signals Sb ₁ and Sb ₂ for each winding layer of the striated body 1.
b is generated based on the determination result of each winding layer of the striatum 1, whereas the misalignment determination signal Sb ₂ is generated based on the determination result of the striatum 1 for each turn, and time is required for the determination. This is because there is a gap. Therefore, the second misalignment judging means 1
When the misalignment determination signal Sb ₁ is generated from 52 and input to the misalignment signal generation circuit 172, the misalignment signal generation circuit 172 generates one winding layer for which the determination result of the first misalignment determination means 152 is output. There holds the alignment defect determination signal Sb ₁ until the end. Second misalignment judging means 1
Be also completed after which the wound layers undergoing misalignment determination signal Sb ₂ from 52 to undergo a misalignment determination signal Sb ₁ from the first misalignment determination means 52, misalignment signal generating circuit 172, inverts clearing the misalignment determination signal Sb ₂ by the signal Sl or Sr.

Also in this embodiment, the number of times of abrupt positional change of one winding layer used in the first misalignment judging means 52 is determined by the width dimension of the drum of the winding drum 14 (length in the axial direction). Of course, it may be obtained by calculation from the dimension) and the pitch of the striatum 1.

In this embodiment, the count value Tp ₂ of the number of times the position signal Sp of the wire feeder 1 in the lateral feed direction of the wire 1 of the wire 1 on the winding drum 14 changes rapidly and comparing the count value Tp ₁ in the number of abrupt changes in the transverse feed direction position signal striatal winding layer before than, to determine that the misalignment occurs when these count values are different first generate the alignment defect determination signal Sb _1, also the winding drum 1
4 abrupt change of the position signal Sp in the transverse feed direction of the striated body 1 for each rotation is within a normal range (between X and X ') determined according to the rotation speed of the winding drum 14. Judge
When no abrupt change occurs in the position signal Sp in the normal range, it is determined that misalignment has occurred, and a second misalignment determination signal Sb ₂ is generated.
Only when it receives b ₁ and Sb ₂ , it generates an alignment error signal Sb ₁₂ . Therefore, according to this embodiment, the striatum 1
Can be double checked. This is advantageous in that misalignment of the striatum 1 can be more reliably detected as compared to the case where only one of the determinations is performed.

[0082]

According to the present invention, as described above, the count value of the number of abrupt changes in the position signal in the transverse feed direction of the filament for each winding layer of the filament on the winding drum (as described above). (The current count value) and the count value of the number of sudden changes in the position signal in the transverse direction of the wire body of the wound layer (the position change obtained from the dimensions of the winding drum and the pitch of the wire body) Number of times)
(The reference count value), and when the current count value is different from the reference count value, it is determined that misalignment has occurred. For each rotation of the winding drum, the position signal of the traverse in the transverse feed direction is determined. Determines whether a sudden change is within the normal range determined by the number of revolutions of the winding drum, and determines that misalignment has occurred if no sudden change in the position signal within the normal range has occurred. Therefore, misalignment can be detected for each winding layer or each turn.

Therefore, irrespective of the rotation of the winding drum, when the cumulative change amount of the supply angle of the filament goes out of the predetermined range, the lateral angle of the filament is returned so that the supply angle returns to the predetermined range. As in the case of the related art in which the feed rate is controlled, the winding may be performed while accumulating the winding errors due to the misalignment without overlooking the misalignment and continuing to wind the striatum. In addition, it is possible to prevent a defective winding appearance.

The normal range of abrupt change of the position signal in the transverse feed direction of the striated body for each rotation of the winding drum is determined by calculating according to the rotation speed of the winding drum. , The misalignment can be accurately detected regardless of the rotation speed of the winding drum.

In particular, the counted value of the number of abrupt changes in the position signal in the transverse direction of the filament for each winding layer of the filament on the winding drum and the filament of the preceding winding layer And a count value (including a value obtained by calculation) of the number of abrupt changes in the position signal in the lateral feed direction of the traverse direction. If these count values are different, it is determined that misalignment has occurred. For each rotation of the take-up drum, it is determined whether or not a sudden change in the position signal of the striated body in the lateral feed direction is within a normal range determined according to the number of rotations of the take-up drum. If no abrupt signal change occurs, it is determined that misalignment has occurred, and if both of these determination signals are received, a misalignment signal is generated, and the winding state of the striatum is double-checked. So that compared to the case where only one judgment is used, The misalignment of the strip member can be more reliably detected.
