Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention holds a cut end portion of a strip-shaped member, for example, a ply cord such as a carcass ply for a tire or a belt layer, and sets a cut edge position thereof. The present invention relates to a method and an apparatus for correcting an edge position of a band-shaped member, which corrects the edge position as described above.

(Prior art) As a conventional device for holding a cut end portion of a band-shaped member,
For example, there is a device proposed by the applicant as Japanese Patent Application Laid-Open No. 64-16630, and as a conventional device for correcting the extending direction of the cut edge while holding the cut end portion of the band-shaped member by suction. This is also disclosed in, for example, Japanese Patent Application Laid-Open No. 64-3073.
There is one proposed as No. 8.

Here, the former pinching device is configured such that the pinching pawls pivoted around the fulcrum by the cylinder are pivotally supported on the front and rear surfaces of the pinching member extending in the width direction of the belt-shaped member, and are placed in a horizontal posture. By bending the cut end portion of a certain band-shaped member upward between the holding body and the holding claw under the action of a bent body that operates to project upward from below, and then by causing the holding claw to swing, The end portion of the band-shaped member is held between the holding member and the holding member, and the latter straightening device is a state in which the gripping means is magnetically attracted to the steel cord-containing band-shaped member along the cutting edge thereof. , Which results in some lifting of the cut end portion, after which the gripping means is
By driving means consisting of a motor and a gear mechanism, in a horizontal plane, a required amount of rotational movement in a required direction,
This is to correct the extending direction of the cutting edge of the band-shaped member as expected.

Among the prior arts, according to the former clamping device, the cut end portion of the band-shaped member can be clamped without fear of damaging it, and according to the latter straightening device, the cutting of the band-shaped member can be performed. When the edge 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.

(Problems to be Solved by the Invention) By the way, the cutting edge of the belt-shaped member is not always straight, and for example, the cutting edge may be curved due to the influence of the embedded state of the steel cord or other reinforcing cord. ,
Where it may be wavy, any of the conventional clamping and straightening devices, there is no way to correct such unevenness such as curved state, wavy state, in the straightening device,
When the band-shaped member is wound around a forming drum, the leading end and the rear end of the band-shaped member are joined together, because the approximate straight line imaginary in consideration of the unevenness of the cutting edge is slightly approximated to the reference straight line. Is a lap joint, the amount of overlap between the front end portion and the rear end portion cannot be made uniform in the width direction of the molding drum, and when the joining is a butt joint, There was a problem that the leading edge and the trailing edge could not be abutted over the entire width of the forming drum without any gap, and therefore, the uniformity of the tire was reduced.

The present invention advantageously solves such a problem of the prior art, and a strip-shaped member capable of extremely effectively correcting unevenness of the cut edge when the cut edge of the strip member is curved or wavy. An object of the present invention is to provide a method and an apparatus for correcting an edge position of a member.

(Means for Solving the Problems) The edge position correcting method of a band-shaped member of the present invention corrects a cutting edge position of a band-shaped member cut on a receiving table, and furthermore, a curved or wavy shape of the cutting edge. In correcting the cutting edge position of the band-shaped member cut on the receiving table, measuring the cutting edge position of the band-shaped member at a plurality of positions in the width direction of the band-shaped member; and cutting the band-shaped member. The step of bending the end portion upward and clamping, and the step of displacing the cutting edge of the band member downward or upward at a required position in the width direction of the band member while maintaining the clamping state are sequentially performed. It is a combination
A straightening device suitable for use in carrying out this straightening method is provided with a support for supporting the band-shaped member, and on the support, a bent body capable of projecting and displacing from the surface thereof is provided. A holding member extending in the width direction of the band member and driven to move up and down with respect to the receiving table is provided in connection with a main frame reciprocated in the direction in which the band member extends, and at least one of the holding members is provided. On the front side, a clamp pawl that is opened and closed with respect to the presser member is pivotally supported, and also on at least one surface side of the presser member, the clamp pawl is arranged side by side in the longitudinal direction of the presser member. Under the cooperation of, a plurality of slide plates sandwiching the band-shaped member over the entire width thereof, is attached to the pressing member so as to be able to move up and down with respect to it, and further, each slide plate,
It is provided with respective driving means, for example, cylinders, which individually raise and lower the holding member with respect to the holding member, and more preferably, in addition to these, specify the amount of downward or rising displacement of each slide plate with respect to the holding member. A cam and rotation driving means for relatively displacing the cam with respect to the slide plate are provided.

In this apparatus, more preferably, the holding member is rotatable in a horizontal plane with respect to the main frame, and driving means for causing the turning movement is connected to the holding member.

(Operation) In the straightening method of the present invention, in particular, in a state where the cut end portion of the band-shaped member is held upward, the cutting is performed at a required position in the width direction of the band-shaped member based on the measurement result of the cut edge position. By displacing the edge downward or upward over a predetermined fixed amount, it is possible to extremely effectively correct the curvature of the cutting edge, waving, etc., which was impossible in the prior art, and as a result, As described above, since the positions of the cutting edges are substantially uniform over the entire width of the belt-shaped member, the occurrence of the above-described problems at the time of lap joint and butt joining of the belt-shaped members can be sufficiently eliminated.

By the way, the cutting edge of the band-shaped member cut on the pedestal has a waveform contour as shown by a thin line in FIG. 6 (a), and an approximate straight line XX of the waveform contour is required. The reference straight line Y-Y, in other words, if it is positioned at an angle θ with respect to a line segment perpendicular to the length direction of the belt-shaped member a, preferably in the preferred straightening device of the present invention, preferably, In a state where the extending direction is substantially parallel to the reference straight line Y-Y, the pressing member is pressed against the band-shaped member a supported on the receiving table, and then the band-shaped member a is moved from the pressed position. The front end portion is bent upward by the action of a bent body projecting upward from the cradle, and the bent front end portion is brought into contact with the surface of each slide plate under the opening of the clamp pawl, and subsequently, , The closing operation of the clamp claw, the band-shaped member The tip portion of the over its entire width, is sandwiched between the clamp jaws, the slide plate subjected to edging treatment on the surface.

Thereafter, the folded body is lowered, and the clamp pawl and the base plate are slightly lifted together with the distal end portion of the band-shaped member a. By pivoting around the center position to a position where the approximate straight line XX substantially coincides with the reference straight line Y-Y, a substantial match between the approximate straight line XX and the reference straight line Y-Y is obtained. As a result, the position of the cutting edge is corrected from the thin line position to the thick line position in the figure.

In this manner, the extending direction of the cutting tip edge is set to the reference straight line Y.
After sufficiently approaching that of −Y, in order to correct the waving phenomenon of the cutting tip edge based on the intrinsic function of the correction device according to the present invention, for example, firstly, by lowering the pressing member, The distal end is placed on the receiving table while being held between the clamp pawl and the slide plate. At this time, the cutting leading edge of the band-shaped member is positioned as shown by enlarging a part thereof in FIG. 6 (b) with an imaginary line, and is greatly curved as shown in the figure.

Next, only the slide plate at the specific position is displaced downward by a predetermined amount to the pressing member and the clamp pawl to the lower limit position specified by the cam, by the operation of the elevation drive means thereof. Thus, the cutting edge portion having a large amount of overhang, the portion corresponding to the slide plates No. 2 to No. 4 as indicated by the imaginary line in FIG. By displacing it rearward, the position of the cutting tip edge is made substantially uniform in the width direction as shown by the thick line in the figure.

Therefore, by performing such a correction of the position of the cutting leading edge over the entire width of the band-shaped member a, the cutting edge is brought to a substantially uniform position over the whole.

With the cutting tip edge position corrected as described above,
More preferably, when the band-shaped member is wound around a forming drum in a state where it is corrected in the same manner as described above so that the post-cut edge position also corresponds to the corrected position of the cut front edge, The leading end portion and the trailing end portion of the band-shaped member can be substantially uniformly overlapped in the width direction, or the leading edge and the trailing edge of the band-shaped member can be abutted without any gap.

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

Further, according to this preferred apparatus, the amount of descending of the slide plate, in other words, the amount of rearward displacement of the cutting leading edge is determined by rotating the cam to a required position by the rotation driving means of the cam. Can be appropriately selected in relation to the wavy state.

By driving, the vehicle can travel in a required direction along the guide rail 2.

Such a main frame 3 has a bracket 6 at the lower end thereof, which protrudes toward the near side as shown in the figure, and an elevating frame 7 is disposed on the bracket 6 here so as to be vertically movable. . The lifting frame 7 allows two sliding rods 8 to pass through both end portions of the bracket 6, and the upper and lower end portions of these sliding rods 8

This is performed by drivingly connecting a pulley 13 attached to an upper end of the belt 12 with a belt 14 and screwing a female screw member 15 fixed to the upper cross bar 9 to the male screw member 12 extending in the vertical direction. be able to.

Here, the holding member 16 is provided below the lifting frame 7.
Are connected rotatably in a horizontal plane, and the holding member 16 is connected to a motor 17 provided on the lower cross bar 10 of the lifting frame 7 and a pinion attached to an output shaft of the motor 17.
Rotational driving is enabled by a driving means comprising an 18 and a sector gear 19 fixed to a connecting shaft between the lifting frame 7 and the pressing member 16.

Further, usually, as shown in a vertical cross-sectional view in FIG. 2 (a), at least one surface side of the pressing member 16 which takes a posture extending in the width direction of the band-shaped member a,
On each of the front and rear surfaces, each clamp claw 20 is pivotally supported by a horizontal axis provided therein, and each of the clamp claws 20 is
, The cylinder 21 and the swing arm connected to each cylinder 21

Here, each of the clamp claws 20 allows the band member a to cooperate with a slide plate to be described later over the entire width thereof without being affected by a variation in the thickness of the band member a in the width direction or the like. In order to clamp sufficiently firmly and uniformly in operation, a plurality of slits 20a extending in the vertical direction are provided at the distal end thereof.

Further, a plurality of slide plates 23 which are opposed to the clamp claws 20 and are arranged side by side in the length direction of the pressing member 16 are disposed below the pressing member 16, and the sliding of the sandwiched band-like member is provided. For the purpose of prevention, these two slide plates 23 whose surfaces have been subjected to edging can be relatively displaced vertically in the window hole 16a provided in the holding member 16 with the holding member 16 separated. Each of the blocks 25 is independently connected to a piston rod 26a of a corresponding one of the cylinders 26 formed on the pressing member 16.

According to this, the block 25 and the slide plate 23 move their holding members based on the supply of pressurized fluid, for example, pressurized air to the upper chamber of the cylinder 26 in relation to the position of the window hole of the holding member 16. It can be displaced downward with respect to the member 16, and conversely, it can be displaced upward by the supply of pressurized air to the lower chamber of the cylinder.

Here, the amount of downward displacement of the slide plate 23 with respect to the pressing member 16 is determined by moving the camshaft 27 provided horizontally through the pressing member 16 and the block 25, respectively.
For example, the surface of each cam 30 provided on the camshaft 27 and the upper wall surface of the through-hole of the block 25 are rotated as necessary by a rotation driving unit including a servomotor 28 and a reduction gear 29. The slide plate 23 can be displaced downward with respect to the pressing member 16 until the upper wall surface of the through hole of the block 25 contacts the cam surface. .

By the way, in the device shown here, the belt-like member is inserted between the slide plate 23 and the clamp claw 20 under a state in which a predetermined space is provided between the upper wall surface of the through hole of the block 25 and the cam surface. In order to prevent the undesired slide plate 23 from performing an insufficient downward displacement together with the band-shaped member when nipping and / or lifting the band-shaped member,
Arm members 31 projecting to one side of each slide plate 23 are fixed to each slide plate 23, and between the arm members 31 and the pressing members 16, as is apparent from the cross-sectional view shown in FIG. A spring 32 for urging the arm member 31 in a direction away from the pressing member 16 is provided.
The downward displacement of the slide plate 23 is restricted by the frictional force between the arm member 31 and the arm member 31.

The apparatus configured as described above is used for use together with auxiliary equipment as shown in FIG. 3, for example.

In FIG. 3, reference numeral 41 denotes a plurality of rollers constituting the transport means of the belt-shaped member a, and reference numeral 42 denotes a pedestal disposed between the rollers at a predetermined position in the transport path. Here, the pedestal 42 functions to clamp the band-shaped member a in cooperation with the pressing member 16 which is moved up and down with respect to the pedestal 42.

Reference numeral 43 denotes a folded body that is housed in the receiving table and extends the band-shaped member a over the entire width thereof.
Reference numeral 43 denotes a lowering position shown by a solid line in the figure and a raising position shown by a virtual line, in other words, a bending position of a rear end portion or a front end portion of the cut strip-shaped member a due to the action of the cylinder 44 attached to the receiving table 42. Can be displaced vertically. Note that the bent body 43 has a groove 45 at the center thereof that allows the passage of a cutting blade of a cutter device described later.

By the way, the cutter device shown in FIG. 46 can be moved in the longitudinal direction of the band-shaped member a as required by a reciprocating drive device (not shown), and the air cylinder 47 can be operated at the cutting position shown in the drawing. As a result, the cutting blades 48 can pierce the band-shaped member a. Further, as is apparent from the schematic front view in FIG. 4, each cutter holding two pairs of the cutting blades 48 is provided. By connecting the apparatus main body portion 49 to the timing belt 52 that is stretched over the pulleys 50 and 51 on the driving side and the driven side, based on the traveling of the timing belt 52, the two cutter device main portions 49 are cut into the cutting blades. Along with 48, strip-shaped member a
Can be separated from each other from the center in the width direction toward each side end thereof.In this separation movement, the respective cutting blades 48 pierced into the center in the width direction of the band-shaped member a A transverse tear can be provided.

In addition, in order to measure the wavy contour of the cutting edge as shown by a thin line in FIG. 6 (a) at the same time as the cutting of the belt-shaped member a by the cutter device 46, for example, Lower running part of timing belt 52
The cutter unit body 49 on the right in the figure connected to 52a
And the left cutter device body portion 49 connected to the upper traveling portion 52b of the timing belt 52, and thus both cutting blades 48
A sensor 53 that can be a sensor for detecting the amount of movement from the center of the belt-shaped member toward the side end, for example, a proximity sensor, a pulse generator, a displacement sensor, or the like.
At a position associated with one of the pulleys 50, and a displacement sensor 54 (see FIG. 3) for detecting the amount of displacement of the cutting blade 48 in the longitudinal direction of the band-shaped member a. .

Therefore, according to this cutter device, after it is moved horizontally to the cutting position shown in FIG. 3, the air cylinders 47 provided on each cutter device main body portion 49 are synchronously operated, and both cutting blades 48 are strip-shaped. At the center position in the width direction of the member a, pierce the band-shaped member a, and then drive both pulleys 50 and 51,
By separating the respective cutting blades 48 from each other in the direction of the side end of the band-shaped member a, the band-shaped member a can be cut, and the width of the band-shaped member a of each of the cutting blades 48 at this time. By detecting each of the direction movement amount and the length direction displacement amount by the sensor 53 and the displacement sensor 54, the wavy contour of the cutting edge can be obtained.

Further, 55 in FIG. 3 shows a means for preventing deformation of the band-shaped member a which presses down the band-shaped member a on the support over the entire width thereof. And a leaf spring 58 fixed to the distal end of the rigid plate 57. The leaf spring 58 absorbs a change in thickness in the width direction of the band-shaped member a, and It has a slit (not shown) spaced apart in the length direction to uniformly lower the member a on the cradle.

According to the deformation preventing means 55 configured as described above, when the band member a is cut by the cutter device 46 and the front end portion and the rear end portion of the band member a are bent by the bent body 43, the leaf spring 58 is used. By rotating the belt-shaped member a by rotating it to the illustrated position, displacement and deformation of the feeding-side belt-shaped member can be sufficiently prevented, and the leaf spring 58 is separated from the surface of the belt-shaped member a. By doing
The belt-shaped member a can be fed out sufficiently smoothly.

When the edge position correcting device is combined with another device as described above, and the cutting edge of the strip-shaped member a is wavy as shown by a thin line in FIG. 6 (a), for example, As described above, the waveform contour is
, And a signal from the displacement sensor 54, and an approximate straight line XX of the waveform contour is also obtained by arithmetically processing these signals.

Here, first, the approximate straight line XX is corrected so as to substantially coincide with, for example, a reference straight line YY extending in a direction orthogonal to the length direction of the belt-shaped member a, and then the waveform is changed. Considering a case in which the unevenness of the contour is corrected so as to be as flat as possible, first, the entire device shown in FIG. The holding member 16 is moved between the bent member 43 and the deformation preventing means 55 on the receiving table 42 by moving the pressing member 16 in the vertical direction. In this case, the cutter device 46
Is displaced in advance to a position that does not interfere with the correction device,
Further, the leaf spring 58 of the deformation preventing means 55 continuously lowers the band-shaped member a from the time of cutting the band-shaped member a.

Next, in a state where the extending direction of the holding member 16 is substantially parallel to the reference straight line Y-Y, the lifting frame 7 is lowered, so that the holding member 16 receives the distal end of the band-shaped member a. pressing on the base 42, subsequently, the folded member 43, by protruding from the cradle 42 upward, by bending the tip portion a ₁ of the belt-shaped member a upwardly, that occasion the bent tip portion a ₁ Then, the clamp claw 20 is opened, and the surface of each slide plate 23 is brought into contact with the surface. Thereafter, the cylinder 21 and the swing arm 22 are actuated to close the clamp claw 20, and the leading end portion a _{1 of the} belt-shaped member a ₁ Over its entire width, the clamp claw 20 and the slide plate 23 in the raised position.
, As shown in FIG. 5 (a).

Thereafter, the folded body 43 is lowered to the original position, the leaf spring 58 is separated from the band-shaped member a, and the pressing member 16 is moved up by the lifting frame 7 to move the band-shaped member a.
With the support member 16 slightly lifted, the holding member 16 is rotated by its rotational driving means around the connecting axis to form an approximate straight line X.
The approximate straight line XX is substantially matched with the reference straight line Y-Y by rotating -X to the position that matches or is closest to the reference straight line Y-Y. It is displaced from the thin line position to the thick line position in FIG.

In this manner, after the extending direction of the cutting leading edge is sufficiently close to that of the reference straight line Y-Y, the belt-shaped member a is temporarily set to the initial posture as shown in FIG. At this time, a part of the leading edge of the band-shaped member is at a position indicated by a virtual line in FIG. 6 (b).

Then, after that, the cutting edge portion where the amount of protrusion is particularly large, the portion corresponding to the slide plates 23 of No. 2 to No. 4 as shown in FIG. By the operation of each cylinder 26, as shown in FIG. 5 (b), the slide plate having its surface subjected to edging by being displaced downward over a predetermined amount to a position where the block 25 and the cam 30 abut. Along with 23, it descends by the same amount as the descending amount. According to this, No. 2 to No. 4 slide plates
The cutting edge corresponding to 23 is displaced downward by a distance 1 as shown by the bold line in FIG. 9 (b), while the edge of the other portion that does not lower the slide plate 23 is maintained at the original position. As a result, the cutting edge of the strip-shaped member a is brought to a substantially uniform position over the entire width thereof.

In this manner, the extending direction of the cutting tip edge is set to the reference straight line Y.
After substantially matching with that of −Y and sufficiently correcting the wavy contour of the cutting leading edge, the band member a is lifted to a predetermined height by raising the pressing member 16 based on the raising of the lifting frame 7, The subsequent rotation of the male screw member 5 conveys the entire straightening device together with the leading end of the band-shaped member a to a not-shown forming drum, whereby the required length of the band-shaped member a is also wound up, also not shown. Withdraw from roll.

Thereafter, the pressing member 16 is lowered to press the tip of the band-shaped member a against the surface of the forming drum, and the clamp claw 20 is released, and the pressing member 16 is raised again to form the band-shaped member. The belt-like member a is left on the drum, and then, by a clamp mechanism or other appropriate operation.
Result of the bent tip portion a _1, a sufficient adhering to the forming drum.

After the leading end portion of the band-shaped member a is delivered to the forming drum by such an operation, the pressing member 16 is caused to retreat again in its raised posture, while the forming drum is rotated to move the band-shaped member a around the Paste all around,
This also pulls out the belt-shaped member a from the winding roll over a predetermined length.

Thereafter, as shown in FIG. 3, the band member a is pressed down by the leaf spring 58, and the band member a is pressed by the pressing member 16 at a position forward of the bent body 43, so that the band member a
With the displacement and deformation of the belt-like member a constrained, cutting by the cutter device 46 over the entire width of the band-shaped member a is performed at a position corresponding to the groove 45.

After performing the fixed-size cutting of the band-shaped member a in this manner,
This results in the retraction of the cutter device 46 and the separation of the leaf spring 58 from the feeding-side band-like member, and the rear end a ₂ of the cut-to-size band-like member a under the action of the bent body 33, It is clamped between the clamp claw 20 and the slide plate 23 on the opposite side from the above.

Here, if the post-cut edge has a wavy contour like the above-described cut front edge and / or the approximate straight line of the cut rear edge is inclined with respect to the reference straight line, then The same operations are performed as for correcting and / or correcting those of the cutting leading edges, so that the trailing edges are also corrected and / or corrected.

And more, raising the lifting frame 7, lifting the rear portion a ₂ of the cut belt-shaped member a, followed by the pressing member 16, together with synchronizing with the rotation operation of the building drum,
The remaining portion of the belt-shaped member a is adhered to the forming drum under the action of a constant tension by causing the belt-shaped member a to advance toward the forming drum at a fixed ratio with the rotational peripheral speed.

By the way, on the forming drum of the front end portion and the rear end portion of the band-shaped member a, overlap bonding or
The butting of the front and rear edges is performed by pressing
By performing the ex post operation, pressing against the forming drum can be performed sufficiently properly.

After a series of operations is completed as described above, the pressing device 16 is raised and retracted, so that the correction device can thereafter repeat the same operation as described above.

Therefore, according to this straightening device, not only can the extending direction of the cutting edge of the band-shaped member be substantially coincident with the reference straight line, but also the waveform contour of the cutting edge is sufficiently corrected, and the unevenness amount is advantageously reduced. Therefore, the leading end portion and the trailing end portion of the belt-shaped member can be substantially uniformly overlapped on the forming drum in the width direction thereof, and the leading edge and the trailing edge of the belt-shaped member can be reduced. The edges can be properly butted and joined.

In the above, one embodiment of the correction device has been described. However, it is also possible to directly connect the pressing members 16 without providing a rotating mechanism for the lifting frame 7.

(Effects of the Invention) Thus, according to the present invention, in particular, the amount of unevenness of the cut edge having wavy unevenness can be effectively reduced, so that the belt-shaped member is wound around the forming drum with high accuracy. It is possible to improve the uniformity of the tire and to greatly reduce the amount of unevenness of the joint.
