Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a belt-like member, such as a tire carcass,
This invention relates to an edge straightening device for a band-shaped member, which supports the cut end portion of a ply cord such as a belt and corrects the cut edge position as desired.

(Prior art) As a conventional device for supporting the cut end portion of a band-like member, for example, there is a device previously proposed by the applicant in JP-A-64-16630, As a conventional device for correcting the extending direction of the cut edge while the cut edge is being held, for example, this device was also disclosed in Japanese Patent Application Laid-Open No.
There is one proposed as No.-30738.

Here, the former supporting device has respective supporting 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 strip member upwardly between the supporting member and the clamping claw under the action of a bending member that protrudes upward from below, and then causing the supporting claw to swing, The end portion of the band-shaped member is supported between it and the supporting 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 supporting device can hold the cut end portion of the strip member without damaging it, and the latter straightening device can hold the cut edge portion 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 wavy due to the buried state of the steel cord or other factors. Conventional supporting and straightening devices use a method of applying a linear guide to the cut hole to correct it.

However, with this method, it is not possible to correct curvature and other defects on the cut edge of a strip with low rigidity embedded in the textile cord, so when the strip is wound around a certain type of drum, overlap bonding may occur In this case, it is not possible to make the amount of overlap between the leading edge and the trailing edge of the strip member uniform in the width direction of the drum, and in the butt joint, the leading edge and trailing edge of the strip member cannot be made uniform in the width direction of the drum. There was a problem in that the tires could not be butted against each other without a gap over the entire width of the molded drum, resulting in a decrease in tire uniformity.

The present invention advantageously solves the problems of the prior art, and can sufficiently effectively correct the unevenness of the cut edge of a strip member when the cut edge is curved or wavy. Accordingly, there is provided an edge correction device for a band-shaped member that can bring the extending direction of a cut edge close to the extending direction of a reference straight line with high accuracy.

(Means for Solving the Problems) The edge correction device for a band-shaped member of the present invention is provided by, for example, using a motor and a gear mechanism, and Connecting rotating frames that rotate in a horizontal plane,
Further below this rotating frame, a plurality of plate-shaped holding members for pressing the band-shaped member onto the pedestal are connected, and an elevating means is provided for integrally raising and lowering these holding members with respect to the pedestal. The holding members, which are attached to the rotating frame and whose end portions are interconnected by vertically oriented hinge pins and which extend in the width direction of the strip member, are allowed to swing relative to each other in a plane parallel to the pedestal. A drive means is provided, and further,
A clamp claw is pivotally supported on at least one surface of each holding member so as to swing in a vertical plane under the action of a cylinder or the like.

<Function> When correcting the extending direction of the cut edge using such an edge straightening device, the cut edge should be adjusted to the desired shape, for example, as shown by the line segment x-x in FIG. 9(a). Reference line segment Y-
Y, in other words, when the strip member a is inclined at an angle θ with respect to a line segment perpendicular to the length direction of the strip member a, the plurality of presser members are aligned in a straight line, and the direction of their extension is 5, in a state substantially parallel to the line segment is pressed onto the pedestal over its entire radius, and then the free end portion of the strip member a is bent upward by the action of a bending body projecting upward from the pedestal,
The bent end portion is brought into contact with the surface of each presser member while the clamp claw is open, and then the clamp claw is operated to close, and the end portion of the strip member a is placed between the clamp claw and the presser member. support

After that, the folded body is lowered, and the presser member is raised somewhat along with the end portion of the band-shaped member a by reactivation of the reciprocating drive means, and the presser member is
By rotating the rotating frame around the central position in the length direction to a position where the line segment x-X coincides with or is closest to the reference line segment Y-Y, the band-shaped member a
Based on the plastic deformation of the end portion of the line segment X-X and the reference line segment Y
-Y, thereby modifying the direction of extension of the cutting edge to the direction of extension of the desired reference line segment Y-Y.

Here, in addition to the above-mentioned modification of the extending direction of the cutting edge, or completely separately from that, in order to eliminate the influence of curvature, waving, etc. of the cutting edge of the strip member a, the outline of the cutting edge is adjusted. In order to properly match the shape and the outline of the cutting trailing edge, it is assumed that the leading and trailing cutting edges have an outline as shown in FIG. 9(b) when wrapped around the drum. If the contour shape of the cutting trailing edge a is to be corrected to a shape corresponding to that of the cutting tip edge a2, first align a plurality of holding members, for example, three holding members in a straight line, and The cutting direction is made parallel to the reference line segment Y-Y of the cutting trailing edge a1, and thereafter, the rear end portion of the strip member a is held by the presser member and the clamp claw in the same manner as described above.

Then, the folding body is lowered and the presser member is raised, thereby lifting the rear end portion of the strip member a somewhat from the pedestal.

By the way, when correcting the trailing edge contour in addition to correcting the extending direction of the cutting trailing edge a,
, the rear end portion of the strip member a is in the above-mentioned lifted position without repeating each of the above-described operations.

Therefore, after that, by relatively swinging each of the three presser members in the required direction, the cutting rear edge a
1 is made sufficiently close to that of the cutting tip edge a2.

To explain this based on the part shown in FIG. 9(C), by rotating the presser member located in the center based on the movement of the rotating frame, the cutting edge portion corresponding to the presser member a. from the imaginary line position in the figure to the solid line position, and also relative oscillation of the free end portion of each presser member connected vertically in the figure to the front side and the rear side respectively by the required amount. By moving the cutting edge portions a+2+ a, 3 corresponding to each of the presser members, these are also brought to the solid line positions in the figure, thereby changing the contour shape of the cutting trailing edge a1. Match the contour shape of the tip edge a2 with sufficient precision. Note that this matching accuracy increases as the number of holding members increases.

After completing the correction of the extending direction of the cut edge and/or the correction of the cut edge contour shape as described above, by winding the strip member a around the oval drum, the leading and rear end portions of the strip member a are separated. It is possible to overlap the strip members almost evenly in the width direction, or to match the leading edge and the trailing edge of the strip member with sufficient accuracy.

If this correction device is used to correct both the extending direction of the cut edge and the contour shape of the cut edge, it is also possible to correct the extending direction after correcting the contour. It is.

A plurality of slits 24 are provided at predetermined intervals in the length direction.

The edge correction device constructed as described above is put into use by arranging it as shown in FIG. 4, for example.

In FIG. 4, reference numeral 31 indicates a plurality of rollers constituting the conveyance means for the belt-shaped member a, and 32 indicates a pedestal disposed between two rollers at a predetermined position within the conveyance path.

Here, the pedestal 32 functions to hold the strip member a in a flat position over its entire width by means of the holding members 21a and 2lb which are moved up and down relative to the pedestal 32.

Further, 33 indicates a folded body that is housed in the pedestal and extends over the entire width of the strip member a14. The lowered position shown 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 33 has a blade holder 35 made of, for example, Teflon, in the center thereof, for receiving and protecting a cutting blade of a cutter device to be described later.

By the way, the cutter device indicated by 36 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 can also be moved by operating an air cylinder 37 at the cutting position shown in the figure. , the cutting blades 38 can be pierced into the strip member a, and as is clear from the schematic front view shown in FIG. Connect the main body portion 39 to the drive side and driven side P! J40.

The cutter device 36 is shown in FIG. 9(a), for example.
In order to measure the contour shape of the cut edge as shown in ) and (b) at the same time as the strip member a is cut, a In the figure, the cutter device main body portion 39 on the right side and the cutter device main body portion 39 on the left side connected to the upper running portion 42b of the timing belt 42, and furthermore,

Therefore, according to this cutter device, after horizontally moving the cutter device to the cutting position shown in FIG. Pierce the strip member a at the center in the width direction of the member a, and then insert both pulleys IJ40. 41 to separate the respective cutting blades 38 from each other in the direction of the side ends of the band-like member a, the band-like member a can be cut. , the amount of movement in the radial direction and the amount of displacement in the length direction of the strip member a are measured by the sensor 43 and the displacement sensor 44, respectively.
By detecting this, the contour shape of the cut edge can be determined.

Further, in FIG. 4, reference numeral 45 denotes deformation prevention means for the belt-like member a, which lowers the belt-like member a over its entire width onto the pedestal. a rigid plate 47 that is rotated by the
The leaf springs 4817 are arranged at intervals in the length direction in order to absorb changes in the thickness of the strip member a in the width direction and uniformly press down the strip member a onto the pedestal. It has a slit (not shown).

According to the deformation prevention means 45 configured in this way, when the strip member a is cut by the cutter device 36 and the front end portion and rear end portion of the strip member a are bent by the bending body 33, the leaf spring 48 By rotating the strip member a 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 4B 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 of the present invention is combined with other devices as described above, for example, the cut rear edge of the band member a has a contour shape as shown in FIG. 9(a). As mentioned above, the contour shape is
It is determined by the signal from the sensor 43 and the signal from the displacement sensor 44, and at the same time, the approximate line segment 18 of the contour shape is also determined by arithmetic processing of these signals.

Here, this approximate line segment X-x is defined as, for example, the strip member a
Considering the case of substantially matching the reference line segment Y-Y extending in the direction perpendicular to the length direction of The holding member 13a is moved in the length direction of the strip member a.
．． 13b is positioned on the pedestal 32 on the front side of the folded body 33. Note that at this time, the cutter device 36
The plate spring 48 of the deformation preventing means 45 has been previously displaced to a position where it does not interfere with the correction device, and the leaf spring 48 of the deformation prevention means 45 continues to press down the band-shaped member a since the band-shaped member a is cut.

Next, the motor 8, pinion 9 and sector gear 10
is activated, the intermediate plate 12, and both presser members 13a. are aligned in a straight line. By lowering the intermediate plate 12 by the cylinder 1l with the extending direction of the intermediate plate 13b substantially parallel to the approximate line segment XX, both presser members 13a. 13b, the rear end of the strip member a is pressed onto the pedestal 32 19 as shown in FIG. By protruding upward from the base 32, the rear end portion ale of the strip member a is bent upward, and the bent rear end portion alQ is

13b, and then the cylinder 22a.
, 22b and the swing arms 23a, 23b to close the clamp claws 21&, 2lb, so that the rear end portion alo of the strip member a is moved over its entire width by the respective clamp claws 21a, 2lb and the holding members 13a. 13b.

After that, the folded body 33 is lowered to its original position, the leaf spring 48 is separated from the strip member a, and
Pressing member 13a. 13b is lifted up together with the strip member a by the lifting of the intermediate plate 12 by the operation of the cylinder 11, and both presser members 13a. 13b is moved by the driving means of the rotating frame 7 around the connection axis 20 times together with the rotating frame 7 to a position where the approximate line segment X-x coincides with or is closest to the reference line segment YY. , based on the plastic deformation of the lifted end portion of the strip member a, the approximate line segment Correct in the Y-Y extending direction.

Even after the extending direction of the cut trailing edge has been corrected in this way, if the contour still curves in the protruding direction as shown by the solid line in FIG. 6(a), the cut trailing edge J!
The above-mentioned edge is made to match the contour shape of the cutting tip edge a2 shown by the imaginary line in the figure, so that the overlap between the front and rear end portions or the butt of the front and rear end portions are sufficiently appropriate. Following the correction process, the presser member 13
a. The rear end portion clamped with each of 13b,
Both presser members 13a based on the operation of motors 15a and 15b
．． 13b is plastically deformed by the forward rocking motion, thereby correcting the contour shape of the cut rear end edge a from the shape shown by the dashed line in the figure to the shape shown by the solid line.

After correcting the extending direction of the cutting trailing edge and correcting the cutting contour as described above, the cutting 21 is performed. With the member a pre-wound around the drum of a certain type, near the circumference, the cut rear end portion of the drum in the lifted position is moved around the drum based on the conveying movement of the straightening device in synchronization with the rotational operation of the drum of the certain type. By conveying in the direction of a certain drum at a speed somewhat lower than the circumferential speed, the remaining part of one strip a is applied to the hollow drum under a constant tension thereon.

By winding the strip member a around the precept-shaped drum in this manner, as described above, the extending direction of the cut trailing edge is corrected to substantially match the direction of the reference line segment YY, In addition, since the contour shape has been corrected to accurately correspond to that of the cutting tip edge, when the tip portion and the rear end portion of the band-shaped member a overlap over a predetermined range, the amount of overlap is can be made sufficiently uniform over the entire width of the strip member a,
Further, when the leading edge and the trailing edge of the band-shaped member a are butted against each other, it is possible to effectively prevent a gap from forming between both edges.

By the way, when the front end portion and the rear end portion of the strip member a are joined on the hollow drum as required, or when the front and rear end edges are butt-jointed, those portions are connected to the holding members 13a and 13b. By subsequent manipulation, this can be done properly by pressing against a certain type of drum.

After completing the series of operations as described above, by returning the straightening device to the position above the pedestal 33, the straightening device can repeat the same operations as described above.

Therefore, according to this straightening device, the extending direction of the cut rear end edge a1 of the strip member a can be made to substantially match the reference line segment, and the contour shape of the cut edge can be adjusted to the desired shape with high precision. It can be corrected in shape, therefore,
The leading end and trailing end of the strip member are placed on a certain type of drum.
It is possible to overlap the strip members almost equally in the width direction, and the leading edge and the trailing edge of the band-shaped member can be properly butt-joined.

23 Above, we have explained the application example of the orthodontic device, but the first
By using the clamp claws on the front side of the figure, it is possible to perform the same corrections and corrections as described above on the cutting edge of the band-like member, as well as adjust the extending direction of the reference line segment as required. You can also change it as appropriate.
