る。2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 1-222933 discloses a belt-shaped member winding device (cord-containing strip winding device) as described above. This device is a conveyor (strip feeding device) driven by a positionable motor. Feeder and forming drum, and a cutter for cutting the strip on the conveyor in parallel with the buried cord, the cutter runs parallel to the buried cord and can be elastically displaced in a direction perpendicular to the cord. If the cutter interferes with the cord at the time of cutting, the cutter is displaced in a right angle direction and cuts the strip parallel to the cord at a position avoiding the cord. In this case, the displacement of the cutter can be detected.

してある。On the other hand, the cutting length of the strip is preset to be slightly shorter than one round of the drum, and the short length is determined by stopping the drum to reverse the conveyor or stopping the conveyor to rotate the drum forward. By means of stretching and winding the material, the front end and the rear end of the strip are aligned after winding, but the actual cutting length of the strip when the cutter is displaced at right angles as described above. Is different from the preset cutting length.
Therefore, in this winding device, the feed amount of the conveyor and the forming drum is relatively controlled based on a preset cutting length and the displacement amount of the cutter, and the starting end of the strip wound on the forming drum is controlled. And the end are matched.
解決しようとする課題 上述のコード入りストリップ巻付装置は、切断時にコ
ードは常にストリップに対して一定のバイヤス角度を有
しており、かつカッタによる切断線は常にコードに平行
な直線であることを前提としている。The above-described cord-wrapped strip wrapping apparatus has the following features: when cutting, the cord always has a certain bias angle with respect to the strip, and the cutting line by the cutter is always a straight line parallel to the cord. It is assumed.
しかし実際にはコードのバイヤス角度はストリップの
始めから終りまで必ずしも一定ではなく各コードのバイ
ヤス角度にバラツキが生じたりすることがある。However, in practice, the bias angle of the cord is not always constant from the beginning to the end of the strip, and the bias angle of each cord may vary.
また切断時におけるカッタの走行は埋設されたコード

ム周面におけるストリップ前端と後端の接合部に重なり
部分と隙間部分とが生ずるが、この重なり量または隙間
量は所定の限界値内に厳密に納めなければならない。Also, since the cutter travels along the embedded cord during cutting, the cutting line is not necessarily a straight line, and a meandering cutting line may be obtained. An overlap portion and a gap portion occur at the joint at the rear end, and the overlap amount or the gap amount must be strictly within a predetermined limit value.

るように制御することはむずかしい。However, when the front end and the rear end are cut as in the above-described conventional example, the right angle displacement of the cutter is detected at one point, and the amount of stretching is corrected based on this displacement.
At the end of winding, the cutting line at the front end and the cutting line at the rear end do not always have the same inclination angle and coincide with each other over the entire width of the strip, and when the cutting line is in a meandering state, the amount of overlap or gap is reduced. It is difficult to control to always stay within a predetermined limit.

ることとを特徴とする。Means for Solving the Problems and Action The present invention has been made in view of such circumstances, and a belt-shaped member cut to a certain length by a cutter on a conveyor is supplied to the drum by the conveyor to thereby form the drum. In winding around the peripheral surface, the cutting length of the band-shaped member is set to be slightly shorter than the peripheral length of the drum, and at the time of winding, the band-shaped member is stretched by a predetermined amount, and after the winding is completed, the front end and the rear end thereof. In the band-shaped member winding method to match with, cut the band-shaped member by running the cutter along a predetermined travel reference straight line, measure the shape of the cutting line at the front end and the rear end, and, Obtaining an approximate straight line, an inclination angle of the approximate straight line with respect to the predetermined travel reference straight line, and a deviation amount of each point on the cutting line from the predetermined travel reference straight line, and calculating the inclination angle obtained with respect to a rear end cut line. The orientation of the rear end cutting line is corrected based on the inclination and the inclination angle obtained for the front end cutting line so that the inclination angle of the rear end cutting line matches the inclination angle of the front end cutting line. Is set on the conveyor, and based on the deviation amounts obtained for the front end and the rear end, a gap amount and an overlap amount generated between the front and rear cutting lines when winding is completed are calculated, and the gap amount is calculated. And the amount of stretching of the belt-shaped member during winding is corrected so that the maximum value of the overlap amount falls within a predetermined value.

はない筈である。The cutting of the band-shaped member is performed, for example, by causing the cutter to travel along a scheduled traveling reference straight line defined by a traveling path member that is erected across the band-shaped member and guides the traveling of the cutter. There may be a slight displacement in the direction perpendicular to the planned running reference straight line, so that the actual trajectory of the cutter, ie, the shape of the cutting line does not always match the planned running reference straight line. Therefore, in the method of the present invention, when cutting the front end and the rear end of the band-shaped member,
For example, the locus of the cutter, that is, the shape (coordinates) of the cutting line is measured by measuring the amount of displacement of the cutter from each scheduled traveling reference straight line at each traveling position. Then, an approximate straight line of the cutting line is calculated from the shape, and an inclination angle of the approximate straight line with respect to the planned traveling reference straight line is calculated. Then, after the rear end is cut, the rear end is held by an appropriate holding means and its posture is changed to correct the inclination angle after the rear end cutting so as to match the inclination angle of the front end cutting line. In this state, the belt-shaped member is set and held on the conveyor. Therefore, when the belt-shaped member is set and held on the conveyor, there should be no angle error between the approximate straight line at the front end and the approximate straight line at the rear end.

る。However, since the cutting line goes back and forth with respect to the approximate straight line, the front end and the rear end overlap in some parts and a gap is formed in some parts. As described above, simply stretching the belt-shaped member by a predetermined amount cannot always keep the overlapping amount of the overlapping portion and the gap amount of the distant portion within the predetermined limit value. Therefore, in the method of the present invention, when the front end and the rear end are cut, the deviation amount of each point on the cutting line from the planned traveling reference straight line is obtained, and the overlap amount and the gap are calculated from the deviation amounts of the front end and the rear end. The amount is calculated, and the stretching amount of the belt-shaped member is corrected so that the maximum value of the overlap amount and the maximum value of the gap amount are both within predetermined limit values.

および隙間量で接合することができる。Thus, even if the strip is not cut linearly at the correct bias angle along the predetermined reference straight line, the front end and the rear end of the strip are joined with the overlapping amount and the gap amount within the predetermined limits after the drum is wound. can do.

もよい。In the above method, based on the inclination angle determined for the rear end cutting line and the inclination angle obtained for the front end cutting line, the inclination angle of the rear end cutting line is equal to the inclination angle of the front end cutting line. The direction of the rear end cutting line is corrected and the belt-shaped member is held and set on the conveyor.Instead, the front end cutting line is cut such that the approximate straight line of the front end cutting line matches the reference straight line at a predetermined angle. Correct the direction of the line and hold and set the front end of the band-shaped member on the conveyor, and correct the direction of the cutting line so that the approximate straight line of the rear end cutting line matches the reference straight line at the predetermined angle. By holding and setting the rear end of the belt-shaped member on the conveyor, the inclination angle of the approximate straight line at the front end and the approximate straight line at the rear end may be matched.

ち切断線の形状はガイドレール25に平行な直線をなす。The cutting of the strip 22 is performed as follows. First, the traveling motor 32 is driven to move the traveling member 27 together with the cutter 40 to one side edge of the belt-shaped member 22 to be positioned. Next, the cylinder device 36 is operated to lower the cutter 40, and as shown in FIG. 8, the V-shaped cutting edge bites into the band-shaped member 22 and reaches the blade receiving plate 47. Is disconnected. Thereafter, when the traveling motor 32 is driven to cause the traveling member 27 to travel along the guide rail 25, the cutter 40

る。However, if the steel cord 23 is located directly below the cutting edge when the cutter 40 is lowered, the reaction force of the rubber portion near the steel cord 23 is large. 40 escapes in a direction perpendicular to the running direction and eventually cuts between the steel cords 23 and cuts the strip 22 along the steel cords 23. Therefore, the trajectory of the cutter 40 is deviated from the planned travel line (planned travel reference straight line) defined by the guide rail 25. If the steel cord 23 is curved, the shape of the trajectory also becomes a curve.

Assuming that the traveling direction of the cutter 40 (the traveling direction of the traveling member 27) is the Y direction and the direction perpendicular thereto is the X direction, the Y
The position in the direction can be digitally detected as a count value by the reflection type optical sensor 43. When the periodic count value is selected, and the count value is detected, the position of the cutter 40 in the X direction is signaled from the distance sensor 46. The data is input to the converter 70 and digitized. Then, the numerical calculation device 69 stores a periodic count value in the Y direction and numerical information in the X direction at each count value as a pair as a Y coordinate and an X coordinate, respectively. The measurement of the Y and X values is, for example, when the cutter 40 is 2 m in the X direction.
The calculation is performed every time the lens moves by m, and the average of five successive Y values is stored in the numerical operation device 69 as a representative Y coordinate of 10 mm in the corresponding X direction.

The numerical operation device 69 also calculates the approximate straight line b of the locus curve a by calculation, and calculates the inclination angle of the approximate straight line b, for example, the deflection angle θ between the straight lines b and f, and the position of each point on the cutting line from the planned running reference straight line. The amount of deviation δ is calculated and stored.

Correction is made so as to match the inclination angle of the approximate straight line b of the cutting curve a. This correction is performed by calculating the difference between the inclination angles at the front and rear ends by the numerical calculation device 69, sending information about the difference to the control device 73, and controlling the rotation of the turning motor 62 by the control device 73. The FIG. 11 is shown by matching the rear cutting curves a 1 and the approximate straight line b 1 to the approximate straight line b of the front cutting curve a.

The strip-shaped member 22 is sucked onto the conveyor belt 9 without changing the corrected rear end cutting line angle. (The front part of the belt-shaped member 22 is always attracted by the fixed magnet block 13a.) Then, the suction device B is raised again so that the succeeding portion of the belt-shaped member 22 is separated from the conveyor belt 9, and the belt conveyor 5 is moved. The belt conveyor 5 is driven by a motor 12 by rotating the entire belt about a pivot 10 so that the front end thereof abuts on the peripheral surface of the drum 1.

Further, instead of the planned traveling reference line, a straight line of the process angle, a straight line of an angle obtained by adding a certain correction value to the process angle, or a straight line of an angle obtained by cutting the rear end of the previous band-shaped member may be employed. In short, the direction of the cutting line is corrected so as to match the reference straight line having a predetermined angle, and the tip is held and set on the conveyor.

修正量は例えば次のようにして算出される。Therefore numerical calculation unit 69 calculates the displacement amount of overlap each Ki not a preparative to (offset amount) and the amount of clearance from the cutting line a, planned travel reference line of a 1 tip rear end thereof the limit value Calculate the amount of stretching correction necessary to fit in the
73, the control device 73 is based on this, the stretching means
76 For example, by controlling the drive motor 3 and the motor 12 at a fixed ratio, the amount of extension of the belt-shaped member 22 is corrected. The enlargement correction amount is calculated, for example, as follows.
一般に、重なり側の限界値h1はコードのラップを避け

って引伸ばし修正量を算出する。すなわち、 Ｒ≦0.5mmのときには、最大重なり部分と最大隙間部
分を同一にするように引伸ばし量を修正する。Ｒ≦0.5m
mであるので重なり量、隙間量ともに0.25mm以内になり
限界値内に納まる。In general, the limit value h 1 of the overlapping side is set smaller than the limit value h 2 of the gap side in order to avoid wrap code,
Now, it is assumed that h 1 = 0.25 mm and h 2 = 0.5 mm. The numerical calculation device 69 calculates the maximum value R of the overlapping amount and the minimum value R of the overlapping amount only when the overlapping portion is included, and calculates the difference R between the maximum value of the gap amount and the minimum value of the gap amount when only the overlapping portion is included. When both the overlapping portion and the gap portion exist, the sum R of the maximum value of the overlapping amount and the maximum value of the gap amount is obtained, and the stretching correction amount is calculated based on the value of R. That is, when R ≦ 0.5 mm, the stretching amount is corrected so that the maximum overlapping portion and the maximum gap portion are the same. R ≦ 0.5m
Since it is m, both the overlap amount and the gap amount are within 0.25 mm, which is within the limit value.
0.5＜Ｒ≦0.75mmのときには、最大重なり量が0.25mm
になるように修正する。Ｒの最大値は0.75mmであるの
で、隙間量は最大でも0.5mmになり限界値内に納まる。When 0.5 <R ≦ 0.75mm, the maximum overlap is 0.25mm
Modify so that Since the maximum value of R is 0.75 mm, the gap amount is at most 0.5 mm, which is within the limit value.
Ｒ＞0.75mmのときにも、最大重なり量が0.25mmになる
ように修正するが、この時には隙間量が0.5mmを越える
ので、異常警報を発する。Even when R> 0.75 mm, the maximum overlap amount is corrected to be 0.25 mm. At this time, since the gap amount exceeds 0.5 mm, an abnormal alarm is issued.
