Description

  The present invention relates to a fiber bundle supply device, and more specifically, uses an array head for arraying fiber bundles sent out from bobbins, and relatively moves the array head and fiber bundle array member to align the fiber bundle array member. The present invention relates to a fiber bundle supply device of a fiber bundle arrangement device that forms a laminated fiber bundle group by being engaged with a pin and folded back.

  As the fiber bundle supply device, as shown in FIG. 5, the fiber bundle F drawn from the bobbin B is moved in a plurality of guide rollers 71, 72, 73, 74, 75 rotating in a predetermined position and vertically. There is an apparatus that guides the fiber bundle F to the array head 77 via a movable roller 76 that performs tension adjustment, and arranges the fiber bundle F by relative movement between the array head 77 and the fiber bundle arrayed member 78.

Further, as a method of controlling the yarn tension in the three-dimensional loom, a method of detecting the yarn tension, comparing the detected value with a predetermined set value, and controlling the yarn tension according to the comparison result Has been proposed (see, for example, Patent Document 1). In this method, as shown in FIG. 6, the thread 82 pulled out from the bobbin 81 is guided to a rapier 86 via pulleys 83, 84, 85, and is turned back by a pulley (not shown) attached to the tip of the rapier 86. One end of the thread 82 is fixed via a pulley 87. Then, the thread 82 is pulled out by the forward movement of the rapier 86 and the bobbin 81 is rotated by the motor 88 in the feeding direction of the thread 82. Further, when the rapier 86 is moved backward, the bobbin 81 is rotated in the direction in which the yarn 82 is wound up. The control unit 89 inputs the output of the rotation sensor 90 as a signal corresponding to the rotation direction, rotation speed, and rotation amount of the pulley 85 via the rotation detection conversion unit 91, and outputs the displacement sensor 92 via the displacement detection conversion unit 93. Then, the displacement amount of the pulley 84 is input. Then, the control unit 89 controls the motor 88 via the motor control unit 94 so that the tension of the yarn 82 becomes a predetermined tension.

  In order to efficiently arrange the fiber bundles by the fiber bundle arranging device (with high productivity), it is necessary to increase the arrangement speed of the fiber bundles within a range in which excessive tension is not applied to the fiber bundles. However, in the above-described fiber bundle supply device, the fiber bundle F is arranged so as to be folded by being engaged with the pins, so that the relative speed becomes zero at the time of folding. When relative movement is started again, it is necessary to increase the relative speed of the array head 77 to a predetermined speed as soon as possible. However, when the fiber bundle F is pulled out suddenly, there is a problem that the generation of fluff increases in the fiber bundle F, the width of the fiber bundle F becomes narrow, or the pin with which the fiber bundle F engages falls. To do. When the cause is analyzed, when the fiber bundle F is pulled out rapidly, the tension applied to the fiber bundle F increases for a while even after passing through the acceleration region of the drawing speed as shown by a chain line in FIG. And it became constant. Then, in the state where the tension surrounded by the broken line in FIG. 4 is increased, the generation of fluff increases in the fiber bundle F, the width of the fiber bundle F decreases, or the pin with which the fiber bundle F engages falls. It was found that this problem occurred.

  In the yarn tension control method described in Patent Document 1, the control unit 89 controls the tension of the yarn 82 to be a predetermined tension based on the output of the rotation sensor 90 and the output of the displacement sensor 92. At that time, the rotation sensor 90 is based on the premise that there is no slip between the pulley 85 and the yarn 82, and the above-mentioned problem cannot be solved.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to suppress the occurrence of slipping between the fiber bundle and the guide roller after the fiber bundle is pulled out in an accelerated state. It is in providing the fiber bundle supply apparatus which can be performed.

  In order to achieve the above object, according to the first aspect of the present invention, an array head is used for arraying fiber bundles fed out from bobbins, and the array head and the fiber bundle arrayed member are relatively moved to move the fiber bundle. It is a fiber bundle supply device of a fiber bundle array device that forms a laminated fiber bundle group by being engaged with a pin on a member to be arranged and folded back. And a bobbin rotating means for positively rotating the bobbin, a guide roller for guiding the fiber bundle sent out from the bobbin, and a driving means for positively rotating the guide roller in the direction in which the fiber bundle is drawn out.

  In this invention, when the fiber bundle is arranged on the fiber bundle arrayed member by the relative movement between the array head and the fiber bundle arrayed member, the guide roller for guiding the fiber bundle is driven by the driving means in the direction in which the fiber bundle is pulled out. It is actively rotated. Therefore, after the fiber bundle is engaged with the pin and turned back, the fiber bundle is pulled out in an accelerated state even if the fiber bundle is arranged by accelerating the drawing speed of the fiber bundle. The occurrence of slipping between the fibers can be suppressed, and excessive tension is prevented from being applied to the fiber bundle.

  According to a second aspect of the present invention, in the first aspect of the present invention, a plurality of the guide rollers are provided, and the driving means drives all the guide rollers. When there are multiple guide rollers, the slip state between the fiber bundle and the guide roller differs depending on the position of the guide roller. Even if it occurs, there are a few. Therefore, it is not always necessary to positively drive all the guide rollers, but it is not necessary to check the occurrence of slippage in each guide roller as long as all the guide rollers are actively driven.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the driving means is configured to be able to drive the guide roller in a reverse direction.
When arranging the fiber bundle, if the arrangement head approaches the folding point of the fiber bundle and the relative speed between the arrangement head and the fiber bundle arranged member is rapidly reduced, the fiber bundle is slackened. In the present invention, when slack occurs in the fiber bundle, it is easy to reverse the guide roller to reverse the slack and arrange the fiber bundle in an appropriate tension state.

  According to a fourth aspect of the present invention, in the first or second aspect of the present invention, the drive means continues the forward rotation drive while the arrangement head is relatively moved in the fiber bundle drawing direction. Therefore, in the present invention, the control of the driving means is simplified. The bobbin that feeds the fiber bundle may be rotated in the direction of winding the fiber bundle depending on the tension state of the fiber bundle. At this time, if the guide roller continues to rotate normally, depending on the position of the guide roller, the guide roller is rotated in the direction opposite to the moving direction of the fiber bundle. However, when the bobbin is rotated in the direction of winding the fiber bundle, the tension of the fiber bundle is weakened. In such a case, there is no problem even if some slip occurs between the guide roller and the fiber bundle. Absent.

  According to the present invention, it is possible to suppress the occurrence of slipping between the fiber bundle after the fiber bundle has been drawn in an accelerated state and the guide roller.

  A linear motor (not shown) of the linear sliders 17 and 18, the motors 22 and 23, the servo motor 31, and the motors 44 and 51 are controlled by the control device C. The control device C controls the motor 23 so that the orientation of the flat portion of the fiber bundle F fed out from the arrangement head 30 corresponds to the arrangement direction of the fiber bundle F. The control device C controls linear motors (not shown) of the linear sliders 17 and 18 so that the arrangement head 30 is moved relative to the frame 15 in the arrangement direction of the fiber bundles F. The control device C controls the motor 31 so as to send out the fiber bundle F with a predetermined tension, and actively rotates the guide rollers 36a, 46a, etc. in accordance with the pulling speed of the fiber bundle accompanying the movement of the arrangement head 30. 44 and 51 are controlled.

  Next, the operation of the fiber bundle arranging device 11 and the fiber bundle supply unit 14 configured as described above will be described. FIG. 3 is a schematic diagram of the guide rollers 36a and 46a and the drive rollers 41a and 48a for explaining the operation. The arrangement intervals of the guide rollers 36a and 46a and the drive rollers 41a and 48a are different from those in FIG.

  Prior to the arrangement of the fiber bundles F, the linear sliders 17 and 18 and the motor 22 are driven so that the guide pipes 30a are arranged at the arrangement start position. And the guide pipe 30a will be in the state located in the outer side of one corner part in the one end side of the X direction of the frame 15 supported by the base part 12. FIG. Next, the fiber bundle F fed from the bobbin B is guided to the guide pipe 30a through the guide roller 36a, the roller 40, the guide rollers 36b and 36c, and the guide rollers 46a and 46b, and is inserted into the guide pipe 30a. Is pulled out from the outlet (tip) of the guide pipe 30a. Then, the tip of the fiber bundle F is fixed at a predetermined position outside the frame body 15. The fiber bundle F is fixed using, for example, an adhesive tape (not shown).

  From this state, the operation of the fiber bundle arranging device 11 is started. The linear slider 17 is driven, and the linear slider 18 is moved in the X direction together with the fiber bundle arrangement unit 13 and the fiber bundle supply unit 14. The servo motor 31 is driven in accordance with the movement of the fiber bundle array section 13, and the bobbin B is rotated so as to send out the fiber bundle F at a speed substantially equal to the moving speed of the fiber bundle array section 13, that is, the moving speed of the array head 30. The The fiber bundle F sent out from the bobbin B in a flat state is drawn from the guide pipe 30a in a state where an appropriate tension is applied by the tension adjusting mechanism 38 and is surrounded by the pins 16 on the frame 15. Are arranged in a state where they are engaged with the pins 16 and turned back.

  In order to efficiently arrange the fiber bundles F by the fiber bundle arranging device 11 (with good productivity), it is necessary to increase the arrangement speed of the fiber bundles in a state where excessive tension is not applied to the fiber bundles F. However, in the fiber bundle arranging device 11, the fiber bundle F is engaged with the pins 16 and arranged so as to be folded, so that the relative speed becomes zero at the time of folding. When relative movement is started again, it is necessary to increase the relative speed of the array heads 30 to a predetermined speed as soon as possible.

  FIG. 4 shows the relationship between the time when the fiber bundle F is pulled out rapidly and the tension applied to the fiber bundle F. In FIG. 4, the arrangement head 30 is accelerated between time T0 and time T1, and then moved at a constant speed from time T1. In the conventional apparatus that does not actively rotate the guide rollers 36a, 36b, 36c, 46a, 46b, the tension applied to the fiber bundle F rises for a while even after passing through the acceleration region of the drawing speed, as shown by the chain line in FIG. , Drop and become constant. Then, in the state where the tension surrounded by the broken line in FIG. 4 is increased, the generation of fluff increases in the fiber bundle F, the width of the fiber bundle F decreases, or the pin with which the fiber bundle F engages falls. This problem occurs. The reason why the tension increases once and then decreases again with the passage of time is because the guide rollers 36a, 36b, 36c, 46a, and 46b start to rotate as the tension increases. Note that the time from the start of acceleration until the tension reaches the peak is less than 1 second, depending on the conditions, and becomes a constant tension in about 1 second.

  In the fiber bundle supply unit 14 of this embodiment, each guide roller 36a, 36b, 36c, 46a, 46b is positively rotated in the direction in which the fiber bundle F is pulled out by the drive rollers 41a, 41b, 41c, 48a, 48b. Therefore, even if the arrangement head 30 moves in a rapid acceleration state and the fiber bundle F is pulled out in a rapid acceleration state, the occurrence of slipping between the fiber bundle F and the guide roller 36a and the like is suppressed. As a result of examining the change in tension over time, the state indicated by the solid line in FIG. 4 was obtained. As is clear from FIG. 4, unlike the conventional apparatus in which each guide roller 36a, 36b, 36c, 46a, 46b is not actively rotated, the tension of the fiber bundle F is hardly increased after the acceleration is finished, and the tension is lowered to a constant tension. is doing. In this configuration in which each guide roller 36a, 46a, etc. is positively rotated, the magnitude of the tension is reduced to about ½ that when the guide rollers 36a, 46a, etc. are not actively rotated. In addition, problems caused by excessive tension applied to the fiber bundle F, that is, fluff is increased in the fiber bundle F, the width of the fiber bundle F is narrowed, and the pin with which the fiber bundle F is engaged falls. The occurrence of the situation was not seen.

According to this embodiment, the following effects can be obtained.
(1) The fiber bundle supply unit 14 includes a bobbin rotating means (servo motor 31 and the like) that positively rotates the bobbin B that sends out the fiber bundle F, and guide rollers 36a, 36b, and 36c that guide the fiber bundle F sent out from the bobbin B. , 46a, 46b, and drive means (motors 44, 51, etc.) for positively rotating the guide roller 36a, etc. in the direction in which the fiber bundle F is drawn. Therefore, after the fiber bundle F is engaged with the pin 16 and turned back, the fiber bundle after the fiber bundle F is pulled out in an accelerated state even if the fiber bundle F is arranged by accelerating the drawing speed of the fiber bundle F The occurrence of slippage between F and the guide rollers 36a, 46a and the like can be suppressed, and excessive tension is prevented from being applied to the fiber bundle F. Therefore, it is possible to prevent the occurrence of problems due to excessive tension applied to the fiber bundle F.

  (2) A plurality of guide rollers 36a, 46a, etc. are provided, and drive means (motors 44, 51, etc.) positively rotate all the guide rollers 36a, 46a, etc. Therefore, the occurrence of slippage between the fiber bundle F and the guide rollers 36a, 46a and the like is reliably suppressed.

  (3) The driving means (motors 44, 51, etc.) continues normal rotation while the array head 30 is relatively moved in the drawing direction of the fiber bundle F. Therefore, the control is simple as compared with the configuration in which the rotation direction of the guide rollers 36a, 46a and the like is changed in accordance with the rotation direction of the state where the fiber bundle is sent out from the bobbin B and the state where the bobbin B winds the fiber bundle F. become. Depending on the tension state of the fiber bundle F, the bobbin B may be rotated in the direction in which the fiber bundle F is wound. At this time, if the guide rollers 36a, 46a, etc. continue normal rotation, the guide roller 36a, 46a, 46a, etc. The roller is rotated in the direction opposite to the moving direction of the fiber bundle F. However, when the bobbin B is rotated in the direction in which the fiber bundle F is wound, the tension of the fiber bundle F is weakened. In such a case, the guide rollers 36a, 46a and the like are placed between the fiber bundle F. There is no problem even if some slip occurs.

  (4) The guide rollers 36a, 46a and the like are rotated at a rotation speed that matches the drawing speed of the fiber bundle F. Therefore, slippage between the fiber bundle F and the guide rollers 36a, 46a and the like is reliably prevented.

  (5) The drive means for driving the guide rollers 36a, 46a, etc. includes drive rollers 41a, 48a, etc. for rotating the guide rollers 36a, 46a etc. in contact with the peripheral surfaces of the guide rollers 36a, 46a etc. . Therefore, it becomes easy to retrofit the drive means without changing the arrangement of the guide rollers 36a, 46a, etc., the support shafts 37a, 47a, etc. constituting the existing fiber bundle supply unit 14.

The embodiment is not limited to the above, and may be embodied as follows, for example.
In the above-described embodiment, the positive rotation of the fiber bundle F in the pull-out direction of the fiber bundle F such as the guide rollers 36a and 46a continues even when the fiber bundle F is pulled back, but when the fiber bundle F is pulled back, the guide roller 36a , 46a and the like may be stopped.

  The drive rollers 41a, 48a, etc., as drive means for rotating the guide rollers 36a, 46a, etc. are not limited to the configuration that can be positively rotated only in the pulling direction of the fiber bundle F, and the guide rollers 36a, 46a, etc. can be driven in reverse. It may be configured. When arranging the fiber bundle F, if the arrangement head 30 approaches the folding point of the fiber bundle F, and the relative speed between the arrangement head 30 and the fiber bundle arrangement member (frame body 15) decreases rapidly, the fiber bundle F Looseness occurs. If the guide rollers 36a, 46a, etc. can be driven in reverse, if the fiber bundle F becomes slack, the guide rollers 36a, 46a, etc. are reversed to eliminate the slack and arrange the fiber bundle F in an appropriate tension state. Easy to do.

  The speed at which the guide rollers 36a, 46a, etc. are rotated is not necessarily limited to the speed that matches the drawing speed of the fiber bundle F. Even if the rotation speed does not match the drawing speed of the fiber bundle F, the occurrence of slipping is suppressed by rotating the guide rollers 36a, 46a and the like in the drawing direction of the fiber bundle F.

  The guide rollers 36a, 46a, etc. do not necessarily have to be positively rotated. For example, a guide roller that easily slips among the guide rollers 36a, 46a, etc. may be examined in advance, and the guide roller that easily slips may be positively driven to rotate.

  The number of guide rollers 36a, 46a, etc. is not limited to the number in the above embodiment, but may be increased or decreased as appropriate according to the arrangement relationship between the bobbin holder 27 and the array head 30. Further, the number of guide rollers is not limited to a plurality and may be one.

The configuration for driving the drive rollers 41a and 48a is not limited to a winding transmission mechanism using a belt or a chain, and may be configured only by a gear transmission mechanism.
○ The drive means for positively rotating the guide rollers 36a, 46a, etc. is not limited to the configuration provided with the drive rollers 41a, 48a contacting the guide rollers 36a, 46a, etc., and the rotation of the motor is wound through a transmission mechanism or a gear mechanism. The support shafts such as the guide rollers 36a and 46a may be rotated.

The motor is not limited to a configuration in which a plurality of guide rollers 36a, 46a, etc. are driven by a single motor 44, 51, but a motor may be provided for each guide roller 36a, 46a, etc.
The tension adjusting mechanism 38 is not limited to the combination of the support arm 39 and the roller 40. For example, the roller 40 may be configured to be biased downward by a constant load spring.

○ The tension adjusting mechanism 38 may be omitted.
The fiber bundle F is not limited to the one wound around the bobbin B in a flat state.
The fiber bundle F is not limited to carbon fiber, and for example, inorganic fiber such as boron fiber, silicon carbide fiber, glass fiber, or organic fiber such as polyaramid fiber or ultrahigh molecular weight polyethylene fiber may be used.

  ○ The fiber bundle array member (frame body 15) is fixed, and the fiber bundle array section 13 and the fiber bundle supply section 14 are moved to relatively move the array head 30 and the fiber bundle array member (frame body 15). As a configuration, a scalar robot may be used.
