Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is directed to the cutting edge position of a band-shaped member such as a carcass ply for a tire, a belt layer, etc. The present invention relates to a method for correcting the edge position of a band-shaped member and an apparatus for the same.

(Prior Art) As a conventional device for holding the cut end portion of a band-like member, for example, there is a device previously proposed by the applicant in Japanese Patent Application Laid-Open No. 16630/1983. As a conventional device for correcting the extending direction of the cut edge while holding the cut edge by suction, for example,
There is a proposal as No. 4-30738.

Here, the former clamping device has respective clamping claws pivoted around a fulcrum by a cylinder on the front and rear surfaces of a clamping body extending in the width direction of the band-shaped member, and is held in a horizontal position. By bending the cut end portion of a certain band-shaped member upwardly between the clamping body and the clamping claw under the action of the bending body that protrudes from the bottom to the top, and then causing the clamping claw to swing, The end portion of the band member is held between it and the holding body, and the latter correction device is
A gripping means is magnetically attracted to the steel corded strip along the cut edge of the strip to cause some lifting of the cut end, and the gripping means is then replaced by a motor and a gear mechanism. The extending direction of the cutting edge of the strip member is corrected as desired by causing the drive means to perform a required amount of rotational movement in a required direction within a horizontal plane.

Among these conventional techniques, the former clamping device can clamp the cut end portion of the band-shaped member without the risk of damaging it, and the latter straightening device can
When the cut edge of the strip member is linearly inclined at a certain angle with respect to a predetermined reference straight line, the extending direction of the cut edge can be made sufficiently close to the reference straight line.

(Problem to be Solved by the Invention) By the way, the cut edge of a band-shaped member is not always straight. For example, the cut edge may be curved or curved due to the buried state of the steel cord or other reinforcing cord. However, there is no way to correct such irregularities such as curvature and waving with conventional clamping and straightening devices. In order to bring the virtual approximate straight line closer to the reference straight line in consideration of , the amount of overlap between the leading end and the trailing end cannot be made uniform in the width direction of the bottom drum, and when the joint is a butt joint, the leading edge and the trailing end of the strip member cannot be made uniform. There was a problem in that the edges could not be butted together over the entire width of the bottom drum without any gaps, resulting in a decrease in the uniformity of the tire.

The present invention advantageously solves the problems of the prior art, and provides a band-shaped member that can very effectively correct the unevenness of the cut edge of the band-shaped member when the cut edge is curved or wavy. The present invention provides a method and device for correcting the edge position of a member.

(Means for Solving the Problems) The method for correcting the edge position of a strip-shaped member of the present invention corrects the cut edge position of a strip-shaped member cut on a pedestal, and also corrects the curvature, waving, etc. of the cut edge. In order to correct the cut edge position of the strip-shaped member cut on the pedestal, the cut edge position of the strip-shaped member is measured at multiple locations in the width direction of the strip-shaped member; and the cutting of the strip-shaped member. The process of bending the end portion upward and clamping it, and while maintaining the clamped state, cut the cut edge of the strip member.
The method is a combination of sequentially displacing the band-shaped member downward or upward at a predetermined position in the width direction. At the same time, a bendable body that can protrude from the surface of the pedestal and can be displaced is arranged on the pedestal, and a presser member that tends to extend in the width direction of the strip member and is driven up and down with respect to the pedestal is provided. is connected to a main frame that is reciprocated in the direction in which the strip member extends, and has a clamp claw pivoted on at least one surface side of the presser member that is operated to open and close with respect to the presser member; Also, on at least one surface side of the presser member, a plurality of slide plates are arranged side by side in the length direction of the presser member and clamp the strip member over its entire width in cooperation with the clamp claws. The slide plate is attached to the presser member so as to be movable up and down relative to the presser member, and is further provided with drive means, such as a cylinder, for independently moving each slide plate up and down with respect to the presser member, and more preferably, In addition to these, a cam for specifying the amount of downward or upward displacement of each slide plate with respect to the holding member, and a rotation drive means for displacing the cam relative to the slide plate are provided.

In this device, it is more preferable that the holding member is rotatable in a horizontal plane with respect to the main frame, and that driving means for causing the rotational movement is connected to the holding member.

(Function) In the straightening method of the present invention, in particular, with the cut end portion of the strip member being held upward, the cut end portion of the strip member may be cut at a predetermined position in the width direction of the strip member based on the measurement result of the cut edge position. By displacing the edge downward or upward over a predetermined amount, it is possible to very effectively correct curved edges, waving, etc. of the cut edge, which was impossible with conventional techniques. As a result, the positions of the cut edges are substantially uniform over the entire width of the strip member, so that the above-mentioned problems in lap joint and butt jointing of the strip member can be sufficiently eliminated.

By the way, suppose that the cutting edge of the band-shaped member cut on the pedestal has a waveform contour as shown by the thin line in FIG. 6(a), and the approximate straight line χ-X of the waveform contour is If the reference straight line Y-Y, in other words, is located at an angle θ with respect to the line segment perpendicular to the length direction of the band-shaped member a,
Preferably, in the preferred orthodontic device of the present invention, first, the holding member is supported on a pedestal by a band-shaped member a in a state where the extending direction of the holding member is substantially parallel to the reference straight line Y-Y. Then, the part of the band member a on the tip side from the pressed position is bent upward by the action of the bending body that protrudes upward from the base, and the bent tip part is held by the clamp claw. is brought into contact with the surface of each slide plate with the opening of It is held between the plate.

Thereafter, while lowering the bent body, the crank pawl and base plate are slightly lifted together with the tip of the strip member a, and are moved in the longitudinal direction of the presser member by a driving means connected to the presser member. By rotating the approximate straight line XX around the center position to a position where it almost coincides with the reference straight line Y-Y, the approximate straight line XX and the reference straight line Y-Y are brought to substantially coincide with each other. According to
Correct the position of the cutting edge from the thin line in the figure to the thick line.

In this way, the extending direction of the cutting edge is set to the reference straight line Y-
After the band-shaped member is brought sufficiently close to that of Y, in order to correct the wavy phenomenon of the cutting edge edge, based on the original function of the straightening device according to the present invention, the band-shaped member is lowered, for example, by lowering the presser member. The tip is placed on the pedestal while being held between the clamp claw and the slide plate. At this time, the cut end edge of the strip member is as shown in FIG. 6(b).
As shown in the enlarged imaginary line, it is greatly curved as shown in the figure.

Next, only the slide plate at a specific position is moved downward by a predetermined amount with respect to the presser member and the clamp claw to the lowering limit position specified by the cam by the operation of its lifting/lowering drive means. According to
In particular, move the cut edge part with a large amount of protrusion, the part corresponding to the slide plates No. 2 to No. 4 shown by the imaginary line in FIG. 6(b), to the rear side by a distance l corresponding to the predetermined amount. to make the position of the cutting edge almost uniform in the width direction, as shown by the thick line in the figure.

Therefore, by performing such correction of the cutting edge position over the entire width of the strip member a, the cutting edge is brought to a substantially uniform position over the entire width.

In a state in which the cutting tip edge position has been corrected as described above, more preferably, the cutting trailing edge position has also been corrected in the same manner as described above so as to correspond to the corrected position of the cutting tip edge. When the band-shaped member is wound around the bottom drum, the leading edge and trailing edge of the band-shaped member should be overlapped almost equally in the width direction, or the leading edge and trailing edge of the band-shaped member should be They can be butted together without any gaps.

According to the preferred straightening device according to the present invention, the position of the cut edge is first corrected, and then the extending direction of the edge is corrected so that the approximate straight line imaginary to the edge coincides with the reference straight line. Alternatively, the position of the cut edge can be gradually corrected by performing a plurality of correction operations.

Further, according to this preferred device, the amount of descent of the slide plate, in other words, the amount of rearward displacement of the cutting edge can be adjusted by rotating the cam to a desired position using the cam rotation driving means. It can be selected as appropriate in relation to the wavy state of the surface.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a front view showing the main parts of the device according to the present invention, and 1 in the figure is a rectangular tube-shaped beam extending in the extending direction of the strip member a, in other words, in the direction perpendicular to the plane of the paper. 2 parts
3 shows guide rails fixed horizontally to both sides of the beam member 1, and 3 shows a main frame whose reciprocating movement is guided by the guide rails 2.

Here, in this main frame 3, a male threaded member 5 extending parallel to the beam member 1 and the guide rail 2 is screwed into a female threaded member 4 fixed thereto, and this male threaded member 5
By rotating and driving by a motor (not shown), it is possible to travel in a desired direction along the guide rail 2.

The main frame 3 has a bracket 6 at its lower end that protrudes toward the front as shown in the figure.
are arranged so that they can move up and down. This lifting frame 7 is constructed by passing two sliding rods 8 through both ends of the bracket 6, and fixing crossbars 9 and 10 to the upper and lower ends of these sliding rods 8, respectively. The lifting frame 7 can be driven up and down by using the output shaft of the motor 11 attached to the main frame 3.
A belt 14 is connected to a pulley (not shown) via a speed reducer, and a pulley 13 attached to the upper end of a male threaded member 12 bearing on the main frame 3 is connected to a pulley (not shown).
This can be done by drivingly connecting the upper cross spar 9 and screwing the female thread member 15 fixed to the upper cross spar 9 into the male thread member 12 extending in the vertical direction.

Further, here, a presser member 16 is provided below the lifting frame 7.
are rotatably connected in a horizontal plane, and this presser member 16 is connected to a motor F provided on the lower cross spar 10 of the elevating frame 7, a binion 18 attached to the output shaft of this motor 17, and the elevating frame 7. It is made rotatable by a drive means consisting of a sector gear 19 fixed to a connecting shaft with the presser member 16.

Also, normally, at least one surface side of the presser member 16 that takes a posture extending in the width direction of the strip member a, here, the front and rear sides, as shown in the longitudinal cross-sectional view in FIG. Each clamp claw 20 is pivotally supported on both surfaces of the clamp claw 2 by a horizontal shaft provided thereon.
By rotating the horizontal shaft using a driving means consisting of a cylinder 21 and a swing arm 22 connected to each cylinder 21, each clamp claw 20 can be opened and closed as required. . FIG. 2(a) shows one of these clamp claws 20 in an open state,
It is a sectional view showing the other in a closed state.

Here, each clamp claw 20 holds the strip member a over its entire width in cooperation with a slide plate to be described later, without being affected by some variation in the thickness of the strip member a in the width direction. In order to clamp the clamp firmly and uniformly during operation, it has a plurality of sulins 20a extending in the vertical direction at its tip.

Furthermore, a clamp claw 20 is provided at the lower part of the presser member work 6.
A plurality of slide plates 23 are disposed facing the holding member 16 and arranged in line in the length direction of the holding member 16, and the surface of these plates has been subjected to an etching treatment in order to prevent the sandwiched band member from slipping. Each slide plate 23
The two pieces located with the presser member 16 in between are placed on the presser member 1.
The pistons of the respective cylinders 26 are fixed to a block 25 which is relatively movable in the vertical direction in the window hole 16a provided in the block 6, and each of such blocks 25 is configured on the upper part of the holding member 16. They are connected to the rond 26a independently of each other.

According to this, the block 25 and the slide plate 23 are operated by the presser member 16 based on the supply of pressurized fluid, such as pressurized air, to the upper chamber of the cylinder 26 in relation to the window hole position of the presser member 16. A downward displacement relative to the member 16 is possible and, conversely, an upward displacement is possible by supplying pressurized air to the lower chamber of the cylinder 26.

Here, the amount of downward displacement of the slide plate 23 with respect to the presser member 16 is determined by the amount of downward displacement of the slide plate 23 with respect to the presser member 16. Each cam 30 provided on the camshaft 27 is rotated as required by a rotation drive means consisting of
This can be determined by appropriately adjusting the distance between the surface of the block 25 and the soil wall surface of the through hole of the block 25. A downward displacement relative to the member 16 is possible.

By the way, in the device shown here, the strip member is inserted between the slide plate 23 and the clamp claw 20 while a predetermined distance is provided between the earth wall surface of the through hole of the block 25 and the surface of the cam. In order to prevent the slide plate 23 from performing an insufficient downward displacement together with its strip during clamping and/or lifting of its strip, each slide plate 23 is provided with an arm extending from its side. While fixing the member 31, between the arm member 31 and the presser member 16, the arm member 31 is separated from the presser member 16, as shown in the cross-sectional view in FIG. 2(b). By arranging the spring 32 that urges in the direction, the downward displacement of the slide plate 23 is restrained by the frictional force between the spring 32 and the arm member 31.

The apparatus configured as described above is put into use together with incidental equipment as shown in FIG. 3, for example.

In FIG. 3, reference numeral 41 indicates a plurality of rollers constituting a conveyance means for the belt-shaped member a, and reference numeral 42 indicates a pedestal arranged between the rollers at a predetermined position within the conveyance path. Here, the pedestal 42 cooperates with the holding member 16 which is moved up and down with respect to the pedestal 42.
It functions to hold the strip member a.

Reference numeral 43 indicates a folded body that is housed in the pedestal and extends the entire width of the strip member a. The lowered position shown by the solid line and the raised position shown by the imaginary line,
In other words, it can be moved up and down between the bending position of the rear end portion or the tip portion of the cut strip member a. Note that this bent body 43 has a groove 45 in its center that allows passage of a cutting blade of a cutter device to be described later.

By the way, the cutter device shown at 46 in the figure can be moved as required in the length direction of the strip member a by a reciprocating drive device (not shown), and also operates an air cylinder 47 at the cutting position shown in the figure. By this, the cutting blade 48
can be pierced into the strip member a, and furthermore, as is clear from the front view of the route shown in FIG. Driving side and driven side pulleys 50.
51 are respectively connected to the timing belts 52 passed over, and based on the running of the timing belts 52, the two-sided blade device main body portion 49 is cut into the widthwise central portion of the strip member a along with the cutting blade 48. The strip members a can be separated from each other toward their respective side ends, and during this separating movement, the strip members a can be torn in the width direction by the respective cutting blades 48 that are pierced into the center of the strip members a in the width direction. can bring.

The cutter device 46 is shown in FIG. 6(a), for example.
) In order to simultaneously measure the undulating contour of the cut edge as shown by the thin line in FIG.
2a, the cutter device main body part 4 on the right side in the figure
9, and a sensor for detecting the amount of movement of the left cutter device main body portion 49 connected to the upper running portion 52b of the timing belt 52, and by extension, the amount of movement of both cutting blades 48 from the central position of the belt-like member toward the side ends; For example, a sensor 53, which can be a proximity sensor, a pulse generator, a displacement sensor, etc., is provided at a position related to one of the booleans IJ50, and furthermore, the sensor 53 is provided with a sensor 53 that can be used as a proximity sensor, a pulse generator, a displacement sensor, etc. Displacement sensor 54 (third
(see figure).

Therefore, according to this cutter device, after horizontally moving the cutter device to the cutting position shown in FIG. By piercing the strip member a at the center position in the width direction of the member a, and then driving both pulleys 50 and 51 to separate the respective cutting blades 48 from each other in the direction of the side ends of the strip member a, The strip member a can be cut, and the amount of movement of each cutting blade 48 in the width direction and the displacement position in the length direction of the strip member a at this time are detected by the sensor 53 and the displacement sensor 54. By doing this, the wavy contour of the cut edge can be determined.

Further, reference numeral 55 in FIG. 3 indicates deformation prevention means for the belt-like member a, which lowers the belt-like member a onto the platform over its entire width. Rigid plate 57 rotated against
and a leaf spring 5 fixed to the tip of this rigid plate 57.
8, this leaf spring 58 absorbs changes in the thickness of the strip member a in the width direction, and the receiver is arranged at intervals in the length direction in order to uniformly press down the strip member a onto the table. It has a slit (not shown).

According to the deformation prevention means 55 configured in this way, when the strip member a is cut by the cutter device 46 and the front end portion and rear end portion of the strip member a are bent by the bending body 43, the leaf spring 58 is By rotating to the illustrated position and pressing down the strip member a, displacement and deformation of the feeding side strip member can be sufficiently prevented, and the leaf spring 58 is separated from the surface of the strip member a. By doing so, the band-shaped member a can be fed out sufficiently smoothly.

When the edge position correction device is combined with other devices as described above, the cut tip edge of the strip member a is
For example, in the case of waving as shown by the thin line in FIG. An approximate straight line XX of the waveform contour is also obtained by arithmetic processing of those signals.

Here, initially, the approximate straight line XX is, for example,
Regarding the case where correction is made to substantially match the reference straight line Y-Y extending in a direction perpendicular to the length direction of the band-shaped member a, and then correction is made to make the unevenness of the wavy contour as close to a flat shape as possible. Considering this, first, the entire device shown in FIG.
6 on the pedestal 42, the bent body 43 and the deformation prevention means 55
be located between. At this time, the cutter device 46 has been previously displaced to a position where it does not interfere with the straightening device, and the leaf spring 58 of the deformation prevention means 55 continues to press down the strip member a since the time of cutting the strip member a. ing.

Next, by lowering the elevating frame 7 with the extending direction of the holding member 16 substantially parallel to the reference straight line Y-Y, the holding member 16 presses the strip member a.
Press the tip of the body onto the pedestal 42, and then press the bent body 43 onto the pedestal 42.
By projecting upward from the pedestal 42,
The tip portion a1 of the strip member a is bent upward, and the bent tip portion a1 is brought into contact with the surface of each slide plate 23 while the clamp claw 20 is opened, and then the cylinder 21 and the swing arm 22 are Each time the clamp claw 20 is actuated, the clamp claw 20 is closed, and the distal end portion a of the strip member a is held between the clamp claw 20 and the slide plate 23 in the ascending position over its entire width as shown in FIG. 5(a).
Clamp as shown.

Thereafter, the folded body 43 is lowered to its original position, the leaf spring 58 is separated from the strip member a, and the presser member 16 is raised somewhat together with the strip member a by the lifting frame 7. , the holding member 16,
The rotation driving means rotates the approximate straight line XX around the connecting shaft to a position where the approximate straight line XX coincides with the reference straight line YY or is closest to it, so that the approximate straight line XX becomes the reference straight line Y-Y. substantially matched, and as a result of this,
The cutting edge is moved from the thin line position in FIG. 6(a) to the thick line position.

In this way, the extending direction of the cutting tip edge is set to the reference straight line Y.
-Y, the belt-like member a is once brought into an initial position as shown in FIG. 5(a). At this time, a portion of the tip edge of the band-shaped member is at the position shown by the imaginary line in FIG. 6(b).

After that, the cutting tip edge where the amount of protrusion is particularly large,
As shown in FIG. 6(b), the portions corresponding to the slide plates 23 of Nos. 2 to 4 are moved to the position shown in FIG. 5(b) by operating the respective cylinders 26. As shown, by moving the block 25 and the cam 30 downward over a predetermined distance until they come into contact with each other, the slide plate 23, whose surface has been etched, is lowered by an amount equal to the amount of the downward movement. According to this, No, 2 to No, 4
The cutting tip edge portion corresponding to the slide plate 23 of
As shown by the thick line in FIG. 9(b), while the slide plate 23 is moved downward by a distance l, the tip edge of the other portion where the slide plate 23 is not lowered is maintained at its original position, and as a result, a band-shaped The cutting edge of member a will be brought to approximately even positions over its entire width.

In this way, the extending direction of the cutting edge is set to the reference straight line Y-
After substantially matching that of Y and sufficiently correcting the wavy profile of the cutting edge, lift the strip member a to a predetermined height by lifting the presser member 6 based on the rise of the lifting frame 7, By the subsequent rotational drive of the male screw member 5, the entire straightening device together with the tip of the strip member a is conveyed to a forming drum (not shown), whereby the strip member a of the required length is wound up (also not shown). Pull out from the roll.

After that, the presser member 16 is lowered to press the tip of the strip member a to the surface of the molding drum, and the clamp claw 20 is released, and the presser member 16 is raised again to mold the strip member. It remains on the drum and is then operated by a clamping mechanism or other suitable operation to bring about sufficient adhesion of the folded end portion a of the strip a to the forming drum.

After the leading end of the strip member a is delivered to the forming drum through this operation, the presser member 16 is moved backward again in its ascending position, while the forming drum is rotated to spread the strip member a around it. Paste it all around the circumference,
This also allows the strip member a to be pulled out over a predetermined length from the take-up roll.

Thereafter, as shown in FIG. 3, the strip member a is pushed down by the leaf spring 58 and the strip member a is pressed by the presser member 16 at a position in front of the folded body 43, so that the strip member a is displaced. , with the deformation restrained, the cutter device 46
Cutting across the entire width of the strip member a is performed at a position corresponding to the groove 45.

After the strip member a is cut to size in this manner, the cutter device 46 is moved backward, the leaf spring 58 is separated from the feeding side strip member, and the cutter strip member a is cut to size. The rear end portion a2 is bent under the action of the bending body 33,
It is held between the clamp claw 20 and the slide plate 23 on the opposite side to that described above.

Note that if the cutting trailing edge has a wavy profile like the cutting leading edge described above and/or the approximate straight line of the cutting trailing edge is inclined with respect to the reference straight line, then , similar operations are performed to straighten and/or modify the trailing edges as well as to straighten and/or modify those of the cutting leading edges.

Furthermore, the elevating frame 7 is raised to lift the rear end a2 of the cut strip member a, and then the presser member 16 is synchronized with the rotational operation of the molding drum and kept constant with its rotational peripheral speed. By advancing toward the forming drum side at a ratio of , the remaining portion of the strip member a is affixed to the forming drum with a constant tension thereon.

By the way, in order to overlap the front end portion and the rear end portion of the band member a on the molding drum as required or to butt the front and rear end edges, those portions are held together by the pressing member 16.
This can be done properly by pressing the molding drum by a subsequent operation.

After completing the series of operations as described above, by raising and retracting the presser member 16, the correction device can repeat the same operations as described above.

Therefore, according to this straightening device, it is possible not only to make the extending direction of the cut edge of the strip member substantially coincide with the reference straight line, but also to sufficiently correct the wavy profile of the cut edge to make the amount of unevenness advantageous. Therefore, the leading end portion and the trailing end portion of the strip member can be overlapped almost equally in the width direction on the forming drum, and
The leading edge and the trailing edge of the band-shaped member can be butt-joined appropriately.

Although one embodiment of the correction device has been described above, it is also possible to directly connect the presser member 16 to the elevating frame 7 without providing a rotation mechanism for the elevating frame 7.

(Effects of the Invention) Thus, according to the present invention, it is possible to effectively reduce the amount of unevenness of the cut edge that is wavy, in particular,
It becomes possible to wrap the band-shaped member around the molding drum with high precision, and the uniformity of the tire is improved, and the amount of unevenness at the joint portion is greatly reduced.
