Description

  The present invention relates to a cord winding system that winds a cord having a small elongation rate due to tension as a sheet-like cord, and a cord winding method using the winding system. In the description of the present specification, the term “sheet cord” is defined and used as a term representing “a plurality of cords arranged in parallel”.

  Conventionally, a plurality of cords such as wires are arranged to form a sheet-like cord, and the sheet-like cord is wound by a winding device. Moreover, when the sheet-like cord is wound by the winding device, the winding operation is performed while the winding tension of the sheet-like cord to be wound is adjusted to be constant and the tension is kept constant.

  At this time, when adjusting the winding tension to a constant state, the winding tension is adjusted so that each cord constituting the sheet-like cord exhibits different elongation depending on the tension tension. Yes.

For this reason, when a plurality of cords with different elongation rates due to tensile tension are wound up as a sheet-like cord, each cord cannot be given different elongation, so a sheet-like cord is constructed. It was not possible to adjust the winding tension of each cord to be constant. In addition, since the winding shape of each cord on the winding shaft of the winding reel of the winding device is a winding shape with different unevenness for each cord, each cord can be wound with the same length. There wasn't.

In the manufacture of tire cords that use a plurality of steel cords with different elongation rates due to tensile tension as sheet-like steel cords, at the stage where a plurality of steel cords are arranged into a sheet-like steel cord, the sheet cord is subsequently A steel cord calender (see Non-Patent Document 1) that winds a rubber-coated sheet-shaped steel cord with a winding device, and multiple steel cords with adjusted tension There has been proposed a tension adjusting device (see Patent Document 1) that forms a sheet-shaped steel cord side by side and applies rubber coating to the sheet-shaped steel cord.

  In the steel cord calendar apparatus described in Non-Patent Document 1, a plurality of steel cords 41 delivered from the creel stand 40 are arranged and knitted into a sheet-like steel cord 42 as shown in FIG. The steel cord 42 is covered with a rubber layer, and the sheet-like steel cord 42 after the rubber coating is cooled by the cooling device 44, and then the sheet-like steel cord coated with rubber by the winding device 45 is used. Is winding up.

  In the step of forming a plurality of steel cords 41 delivered from the creel stand 40 into a sheet-like steel cord 42, the tension of each steel cord 41 is kept constant by using a tension adjusting device as described in Patent Document 1. It can be.

  As a result, the sheet-like steel cord 42 having a constant tension can be covered with a predetermined thickness of rubber in the roll calender 43, and tire materials such as plies, breakers, and belts can be manufactured. . Moreover, tire materials such as plies, breakers, belts and the like having a predetermined width manufactured in a state where the tension of each steel cord is kept constant by rubber coating can be wound up by a winding device.

However, in the conventional apparatus, as described above, since a plurality of cords having different elongation rates due to tensile tension are arranged into a sheet-like cord cannot be wound in the winding device as it is, for example, a tire As in the production, the sheet-shaped steel cord had to be covered with a rubber and then wound with a winding device.

For this reason, in order to wind up a plurality of steel cords with different elongation rates due to tensile tension and wind them up as a sheet-like steel cord, a rubber roll calendar roll, a cooling device, etc. are connected between the winding device and a device such as a grill stand. It was necessary to install in the factory, and the equipment had to be enlarged. Further, when a rubber-coated sheet-like steel cord is wound up, the bulk is increased by the amount of the rubber coating layer, and the amount of winding cannot be increased. In addition, it is necessary to secure a large place for storing the rubber-coated sheet-like steel cord.
Japanese Utility Model Publication No. 1-16599 Rokuro Hattori's “Tire Story” published by Taiseisha, 1992, p. 124

In the present invention, a sheet-like cord in which a plurality of cords having different elongation rates due to tensile tension are arranged can be directly wound without any special treatment such as rubber coating, and each cord has the same length. It is an object to provide a cord winding system and a winding method that can be wound.

The object of the present invention can be achieved by the invention described in claim 1 .
That is, as described in claim 1 in the present invention, a creel stand that rotatably supports a plurality of cord bobbins each wound with a cord, and a winding device that winds each cord unwound from the creel stand side by side, wherein a cord winder system comprising a delivery amount adjusting device arranged between the click reel stand and the winding device, will be back tension applying mechanism is disposed in the vicinity of each code bobbins of the creel stand, said delivery amount adjusting device, the feed amount of each code have a delivery amount adjusting means comprising a plurality of feed rolls which are driven and controlled to be constant, the delivery amount adjusting means, wherein each code is parallel to each other In such a state, it is sequentially wound between the supply rolls, and a press roll is arranged on at least one of the plurality of supply rolls, Each cord is pressed between the supply roll and the press roll, and the back roll is applied between the supply rolls by reducing the conveyance speed of the supply roll arranged on the upstream side from the conveyance speed of the supply roll arranged on the downstream side. The most important feature is a cord winding system characterized by this.

In the present invention, when a plurality of cords that have been unwound from a creel stand, and in particular have different elongation rates due to tension, are wound as a sheet-like cord directly with a winding device, the reel stand and the winding device are The arranged delivery amount adjusting device is provided with delivery amount adjusting means for making the delivery amount of each cord constant.

  As a result, the sheet-like cord in which the feeding amount of each cord from the feeding amount adjusting device is constant can be directly wound by the winding device. For this reason, even if the winding shape of each cord is different in the sheet-like cord, the feeding amount of each cord sent from the feeding amount adjusting device is constant, so that the winding length of each cord varies. Can be prevented.

  According to the present invention, the winding length of each cord in the sheet-like cord is made constant, that is, the winding length of the sheet-like cord in which the cords are arranged and the intervals between the cords are kept substantially uniform is made constant. It becomes possible to wind up with.

  By synchronizing the feeding speed from the feeding amount adjusting device of each cord and the winding speed of the sheet-like cord in the winding device, the feeding amount of each cord from the feeding amount adjusting device and the winding by the winding device It is possible to have a one-to-one relationship between the winding lengths of the respective cords forming the sheet-like cords. When the sending speed and the winding speed are different, a dancer means or the like can be arranged between the sending amount adjusting device and the winding device to absorb the speed difference.

  As the delivery amount adjusting means, a configuration is used in which a plurality of supply rolls that are driven and controlled are used, and each cord is wound around each supply roll in a parallel state and with the spacing between adjacent cords maintained substantially uniform. It can be. The winding angle of each cord around each supply roll needs to be 180 degrees or more. Desirably, a winding angle of 210 degrees or more is desirable in order to reduce slippage between the supply roll and each cord and to convey each cord in a substantially non-slip state by the rotational driving force of each supply roll. .

  Each supply roll can be rotated together by using a gear mechanism, a chain mechanism, or the like. Further, it is possible to provide a motor that can be driven and controlled for each supply roll, and to drive and control each supply roll independently.

  The roll diameter of each supply roll can be made different, but in order to perform control to send out each cord while keeping the feed amount from the feed amount adjusting device constant, the roll diameters of the respective feed rolls are all set to the same roll diameter. This is desirable because the drive control of each supply roll is facilitated. When the roll diameters of the supply rolls are all the same, it is desirable that the winding angles of the cords with respect to the supply rolls are all set to the same winding angle.

  It is desirable to form each supply roll so that each cord is transported in a non-slip state, but at least a supply roll disposed downstream of each supply roll is transported in a non-slip state. It is desirable to configure.

  Since each cord is transported in a non-slip state by the supply roll, the structure of the supply roll is to form an uneven surface on the surface of the supply roll or to cover the surface of the supply roll with a chrome layer, a tungsten layer, a resin layer, etc. Various conventionally known means can be employed. Furthermore, a non-slip state can be formed by reducing the conveyance speed of the supply roll together with the formation of the supply roll described above.

  As a delivery amount adjusting means, each cord is pressed between the supply roll and the press roll using a press roll, a running resistance is given to each cord, and each cord is non-slip by the supply roll in a non-slip state. It can also be transported. The press roll is provided on at least one supply roll, and it is preferable that the press roll is provided on the supply roll disposed on the upstream side. It is also possible to install a press roll on the downstream supply roll so that sheet-like cords are fed from the downstream supply roll in a non-slip state.

  As the press roll, a pressing means such as a pressure contact shoe can be used in addition to the roll rotated by the supply roll. Moreover, a press roll can also be arranged with respect to all the supply rolls.

  The pressing force of the press roll can be performed using the pressing force of a piston that is driven and controlled. Moreover, the pressing force of each press roll can be controlled individually, or the pressing force of a plurality of press rolls can be controlled in conjunction with each other.

  Back tension can be applied to each cord supplied by a plurality of supply rolls. As a method for applying the back tension, a method of applying a load due to the urging force of a weight or a spring to the cord pulled out from the bobbin, a method of applying the cord by meandering the conveyance path of the cord, or the like can be used. . Further, back tension can be applied by using a method in which the conveyance speed of the supply roll is made lower than the conveyance speed of the downstream supply roll as it goes upstream.

  In addition, braking means such as a press roll and a brake shoe are arranged on the drive shaft of the supply roll arranged on the upstream side, and the conveyance speed of the supply roll arranged on the upstream side is set higher than the conveyance speed of the supply roll arranged on the downstream side. Back tension can also be given by reducing.

  The back tension can be applied by reducing the roll diameter of the supply roll as it goes upstream, or by appropriately combining the above-described methods for applying the back tension. Furthermore, a back tension can be applied to each cord by adopting a known method for applying a back tension.

  In the present invention, by applying back tension to each cord, transporting while maintaining a parallel state, increasing the transporting force of the supply roll using a press roller, and combining these, The code can be sent out from the sending amount adjusting device with a fixed sending amount.

Thereby, in the winding device, it is possible to wind the sheet-like cords supplied at a constant feed amount, that is, those in which the respective cords are arranged at substantially uniform intervals, at a constant winding length. It becomes like this. For this reason, a sheet-like cord in which cords having different elongation rates by tension are arranged is wound as it is with a winding device with a certain winding length without performing any special treatment on the sheet-like cord as in the prior art. Can do.

  Another independent invention in the present invention relates to a method for winding a sheet-like cord using the above-described sheet-like cord winding system. In the invention relating to this winding method, each cord is supplied to the delivery amount adjusting device in a parallel state, and the delivery amount of each cord maintained in the parallel state from the delivery amount adjusting device is kept constant. A sheet-like cord is sent out, the sheet-like cord is supplied to the winding device, and the winding device winds up the sheet-like cord at a predetermined winding speed.

  Each cord is supplied to the delivery amount adjusting device in a parallel state, and each cord is transported through the delivery amount adjusting device while maintaining the parallel state, while maintaining the parallel state. It can be sent from the delivery amount adjusting device. As a result, the carrying amount of each code can be made the same. In addition, the transmission amount of each code from the transmission amount adjusting device can be made constant.

  When winding a sheet-like cord in which each cord with a fixed delivery amount is arranged with a winding device, the feeding amount is constant by setting the winding speed at the winding device to a predetermined winding speed. The formed sheet-like cord can be wound with a certain winding length.

  Although it is desirable that the delivery speed from the delivery amount adjusting device and the take-up speed at the take-up device are the same, if the delivery speed and the take-up speed are different, the delivery amount adjustment device and the take-up device It is also possible to absorb the speed difference using dancer means or the like. The winding speed of the winding device is determined by detecting the winding diameter of the sheet-like cord wound by the winding device and controlling the peripheral speed at the winding diameter, that is, the winding speed. The speed can be controlled constant.

  Further, by feeding each cord in a non-slip state while applying a back tension to each cord, the sending amount of each cord sent from the sending amount adjusting device can be made constant. The means for applying a back tension to each cord and the means for conveying each cord in a non-slip state can be performed by using each of the configurations described in the above-described sheet-like cord winding system.

  The cord that can be used in the sheet-like cord winding system and the sheet-like cord winding method of the present invention is not particularly limited as long as it is a cord that has a small elongation rate by pulling. When used as a part of a manufacturing apparatus, a synthetic fiber cord using a fiber such as steel cord, nylon, polyester, rayon, vinylon, or aramid can be used as the cord.

  The thickness of the cord suitable for use in the present invention is, for example, about 1840 dtex / 2 for a rayon cord, about 1670 dtex / 2 for a vinylon cord or an aramid cord, and about a steel cord. It is the thickness before and after the code of thickness such as 1 × 5 (book) × 0.23 mm and the numerical value shown here.

  The tensile properties of these cords include steel cords with an elongation of less than about 1% at a tensile strength of 200N, and elongations of about 1 to 2% at 400N. Aramid cords have a tensile strength of 200N. The elongation is about 2-3% at 400N, the elongation is about 3.5-4.5% at 400N, and the vinylon cord has an elongation of about 3.5-4.5% at a tensile strength of 200N. If the cord is made of rayon, the elongation can be about 8.5 to 9.5% at a tensile strength of 150N.

  Note that the types of cords that can be used in the present invention and the elongation of each cord with respect to the thickness and tensile strength are not limited to the above-mentioned numerical values, but are exemplified as numerical values.

  Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. In addition, this invention is not limited to the Example demonstrated below, A various change is possible.

FIG. 1 shows a schematic diagram of the overall configuration of the present invention. In the sheet-like cord winding system 1, the creel stand 2 rotatably supports a plurality of cord bobbins 4 wound with cords 5 having different elongation rates due to tension. Each cord bobbin 4 or a spindle (not shown) that supports the cord bobbin 4 is provided with a conventionally known braking means so that the cord 5 is rewound with a predetermined unwinding tension. Yes.

  In the vicinity of each bobbin 4 of the creel stand 2, a back tension applying mechanism 31 can be provided as shown in FIGS. The back tension applying mechanism 31 is provided with a plurality of guide pins 32, and the cords 5 drawn from the bobbins 4 of the creel stand 2 are wound around the guide pins 32. At least one guide pin 32 is provided with a receiving portion 33 and a pressing plate 34.

  The cord 5 runs while meandering between the guide pins 32, and a back tension is applied to the cord 5. Further, the cord 5 is inserted between the receiving portion 33 and the presser plate 34, and a back tension is applied to the cord 5 by the weight 35. By changing the weight of the weight 35, the strength of the back tension can be adjusted. Instead of the weight 35 described above, a back tension can be applied by applying a biasing force of a spring to the presser plate 34. In this case, the biasing force of the spring can be configured to be adjustable.

  Further, a back tension can be applied to the cord 5 by hanging the cord 5 a plurality of times by staking between the plurality of guide pins 32.

  The rewinding of the cord 5 from the cord bobbin 4 can be performed by rewinding in the horizontal direction or rewinding in the vertical direction. By performing rewinding in the longitudinal direction, the cord 5 can be twisted. Therefore, depending on the intended use of the sheet-like cord 6, vertical orientation or horizontal orientation can be selected. Furthermore, the number of the cords 5 to be pulled out from the creel stand 2 can be set according to the application in which the sheet-like cord 6 is used.

  The plurality of cords 5 drawn out from the creel stand 2 are aligned with a predetermined width by the alignment roll 26, and are carried into the delivery amount adjusting device 10 with the interval between the adjacent cords 5 being substantially uniform. A sheet-like cord 6 composed of a plurality of cords 5 carried into the delivery amount adjusting device 10 has a constant delivery amount from the delivery amount adjusting device 10 while maintaining a predetermined width and a substantially uniform interval via the guide roll 14b. Sent out.

  The sheet-like cord 6 delivered from the delivery amount adjusting device 10 is supplied to the traverse guide 27 via the guide roll 25 while the tension is adjusted by the tension adjusting roll 18, and between the cords 5 of the sheet-like cord 6. Is supplied to the winding device 20 while maintaining a constant interval. A configuration in which a plurality of codes 5 are sent from the sending amount adjusting device 10 at a constant sending amount will be described later.

  As shown in FIG. 4, the traverse guide 27 is configured such that a comb-like member 28 screwed with a ball screw 30 that is rotationally driven by a servo motor 29 can reciprocate in the left-right direction in FIG. 4. In FIG. 4, for example, when 100 cords 5 are wound on a winding reel having a width of 600 mm by the winding device 20, the cord can be traversed with a width of 6 mm. The traverse width can be adjusted according to the number of windings of the cord 5 as the wire cord 6. Moreover, it can guide so that the code | cord | chord 5 may pass one by one in each comb-shaped recessed part. If necessary, it is possible to guide the plurality of cords 5 so as to pass through each of the recesses and appropriately adjust the traverse width.

  In the present invention, the conveying state of the sheet-like cord 6 between the above-described aligning roll 26 and the guide roll 25 disposed on the downstream side of the delivery amount adjusting device 10 is such that the plurality of cords 5 are maintained at substantially uniform intervals. However, it is desirable to be conveyed in a parallel state. At least in the delivery amount adjusting device 10, it is desirable to configure the plurality of cords 5 as sections in which they are conveyed in a parallel state while maintaining a substantially uniform interval.

  The sheet-like cord 6 composed of a plurality of cords 5 delivered from the delivery amount adjusting device 10 is adjusted in tension by the tension adjusting roll 18, then changed in direction by the guide roll 25, and conveyed to the traverse guide 27. The The sheet-like cord 6 carried into the traverse guide 27 is taken up by the take-up reel 22 of the take-up device 20 as the traverse guide 27 reciprocates in the axial direction. The tension adjusting roll 18 can adjust the tension of the sheet-like cord 6 by controlling the protruding amount of the cylinder 17.

  In the winding device 20, the rotating shaft 21 is rotated by a driving motor (not shown) so as to have a winding speed synchronized with the sending speed of the plurality of cords 5 sent from the sending amount adjusting device 10 by a control device (not shown). The rotation is controlled.

  The winding speed can be controlled by measuring the winding diameter of the sheet-like cord 6 wound around the winding reel 22 to control the winding speed, that is, the peripheral speed during winding. . The winding diameter of the sheet-like cord 6 can be measured by using a conventionally known appropriate measuring means. The configuration of the winding device 20 is not limited to the configuration of the above-described embodiment, and the winding device can be configured to reciprocate in the traverse direction. The configuration can be adopted.

  Since the delivery amount or delivery speed of the plurality of cords 5 delivered from the delivery amount adjusting device 10 is constant, the winding device 20 has a different winding shape for each cord 5 and the winding location. Even if irregularities or the like occur in the case, each cord 5 is wound while being tightened or wound while being loosened, so that the winding amount of each cord 5 wound on the take-up reel 22 is always constant. As you can wind up.

  For this reason, all the winding amounts of the plurality of cords 5 wound around the winding reel 22 can be made the same winding amount. Thus, even when the sheet-like cord 6 is rewound from the take-up reel 22 and processed into a desired product, a sheet-like cord having a certain length can be taken out.

  FIG. 2 shows a schematic enlarged view of the delivery amount adjusting apparatus 10. As shown in FIG. 2, the delivery amount adjusting means for delivering a plurality of cords 5 with a constant delivery amount from the delivery amount adjusting device 10 includes three supply rolls 11a to 11c and upstream of the supply rolls 11a and 11c. And guide rolls 13a and 13b arranged on the downstream side, guide rolls 14a and 14b arranged on the inlet side and outlet side of the delivery amount adjusting device 10, and a press roll 12 that presses the supply roll 11a arranged on the upstream side, It comprises brake means (not shown) for applying a braking force to the supply rolls 11a and 11b.

  As shown in FIG. 3, in the delivery amount adjusting device 10, the plurality of cords 5 are maintained in a parallel state while maintaining a substantially uniform interval, and the supply rolls 11 a to 11 c and the guide rolls 13 a and 13 b are maintained. Traveled and transported in a state of being wound around.

  The winding angle of each of the supply rolls 11a to 11c is about 210 degrees in the example shown in FIG. The number of supply rolls and the winding angle are not limited to three and about 210 degrees, respectively, and the number of supply rolls can be three or more, and the winding angle is 180 degrees or more. It is desirable to wrap around.

  Slipping between the cords 5 occurs by forming an uneven surface on each surface of the supply rolls 11a to 11c, or covering the surface of the supply roll with a chrome layer, a tungsten layer, a resin layer, or the like. It is formed in a structure that does not.

  As shown in FIG. 2, each supply roll 11a-11c is comprised by the drive motor 15 via the gearwheels 16a-16d, and it is comprised so that it may rotate at equal speed. The rotation direction of each supply roll 11a-11c rotates in the direction which conveys the code | cord | chord 5 from an upstream to a downstream. The supply rolls 11a to 11c can be driven to rotate using a chain transmission mechanism instead of being driven to rotate using a gear transmission mechanism.

  A braking means is provided on a rotating disk (not shown) fixed to the rotating shafts of the supply rolls 11a and 11b, and the rotational speeds of the supply roll 11a and the supply roll 11b are reduced. By reducing the rotation speed of the supply rolls 11a and 11b, a back tension can be applied to each cord 5 transported between the supply rolls 11a to 11c.

  By controlling the rate at which the rotation speed of the supply roll 11a and the supply roll 11b is reduced, the magnitude of the back tension can be adjusted. Further, the braking means is not necessarily provided on both supply rolls of the supply rolls 11a and 11b, but can be provided on one of the supply rolls.

  Moreover, a press roll can be provided as a braking means, and the rotation of the supply rolls 11a and 11b can be decelerated. FIG. 2 shows an example in which the press roll 12 is arranged on the supply roll 11a, and the pressing force of the press roll 12 against the supply roll 11a can be adjusted by a pressing means (not shown).

  A press roll (not shown) is arranged on the supply roll 11c arranged on the downstream side, and the pressing force of the press roll against the supply roll 11c can be adjusted. Thereby, by adjusting the pressing force of the press roll, each cord 5 can be sent from the feed amount adjusting means without causing slippage between each cord 5 and the supply roll 11c. You can also.

  The guide rolls 13a and 13b are arranged on the upstream side of the supply roll 11a arranged on the upstream side and the downstream side of the supply roll 11c arranged on the downstream side, respectively, and these guide rolls 13a and 13b are arranged on the supply roll 11a. And 11c to obtain a winding angle.

  1 and 2 show an example in which a tension adjusting roll 18 adjusted by a cylinder 17 is arranged as a tension adjusting means on the downstream side of the guide roll 14b. The rotation position of the tension adjusting roll 18 is adjusted so that a predetermined tension is applied to the sheet-like cord 6 delivered from the supply roll 11c.

  For example, when applying a tension of 400 to 500 g per one cord 5, when sending 100 cords 5, the cylinder 17 can be adjusted so that a total tension of 40 to 50 kg is applied. The tension adjusting means can be arranged on the upstream side of the delivery amount adjusting device 10 as necessary.

  By configuring the delivery amount adjusting means in the delivery amount adjusting device 10 as described above, each cord 5 can be conveyed in a non-slip state with the supply rolls 11a to 11e in the delivery amount adjusting device 10. The sending amount of each code 5 sent from the sending amount adjusting device 10 can be made constant.

  In the present invention, since the delivery amount of the plurality of cords 5 sent from the delivery amount adjusting device 10, that is, the delivery amount of the sheet-like cord 6 or the delivery speed of the sheet-like cord 6 is constant, In the winding device 20, even if the winding shape of each cord 5 is different and unevenness is generated, each cord 5 is wound while being tightened or wound while being loosened, and the winding reel 22 is wound. Thus, the winding amount of each cord 5 wound on the wire can be wound in a constant state.

  For this reason, all the winding amounts of the plurality of cords 5 wound around the winding reel 22 can be made the same winding amount. Thus, even when the sheet-like cord 6 is rewound from the take-up reel 22 and processed into a desired product, a sheet-like cord having a certain length can be taken out.

The present invention, in addition to winding the sheet-like code having different elongation by pulling with a constant winding amount, the winding system which can be wound with different sheets of elongation by pulling with winding amount constant Can be applied.
