Japanese Patent No. 2951068

By the way, as the tension of the knitting yarn at the time of knitting, the tension measured value measured at a position as close as possible to the knitting needle, that is, a position after passing through the yarn feeder, is used in consideration of the influence on the knitted fabric to be knitted. It will be preferable.

In the conventional tension measuring device, since it is the tension measurement value of the knitting yarn measured at the position before passing through the yarn feeder, there is a difference from the tension of the knitting yarn at the position after passing through the yarn feeder. It is undeniable that the tension of the knitting yarn cannot be accurately grasped at the position after passing through the yarn feeder.

Moreover, since the knitting yarn during the tension measurement is supplied to the knitting needle at a high speed, even if there is an abnormality in the tension measurement value of the knitting yarn, the knitting is continued due to inertia, and the knitting is in the middle of knitting. There is a risk of problems with the knitted fabric.

The present invention has been made in view of this point, and an object of the present invention is to use a measurement path different from the thread feeding path to the knitting needle in a state where the knitting yarn can be knitted at a position after passing through the yarn feeding port. By pulling in with the yarn feeder stopped and measuring the tension, it is possible to grasp an accurate tension comparable to that of knitting yarn that is knitted at the position after the yarn feeder has passed, and knitting due to an abnormality in the tension measurement value of the knitting yarn. It is an object of the present invention to provide a tension measuring device for a knitting machine and a method for measuring the tension thereof, which can prevent defects in the ground.

In order to achieve the above object, in the present invention, as a tension measuring device of a knitting machine, a knitting yarn that has passed through a yarn feeding path to a knitting needle in a state where tension is applied to the knitting yarn from the yarn package is fed to the yarn feeding path. It is assumed that the knitting machine is guided by the clues so that the yarn is supplied to the knitting needle. Further, in the vicinity of the yarn feeding port, a tension measuring device main body for measuring the tension of the knitting yarn by drawing the knitting yarn into a measuring path different from the yarn feeding path to the knitting needle at a position after passing through the yarn feeding port. Install. Then, the knitting yarn pulling means for pulling the knitting yarn into the measuring path in a state where the knitting yarn can be knitted at the position after the yarn feeding port has passed through the tension measuring device main body, and the knitting yarn pulling means for the yarn feeding port and the measuring path. A measuring means for measuring the tension of the knitting yarn provided between the knitting yarns and the knitting yarns drawn into the measuring path without knitting by the knitting yarn drawing means, and a knitting yarn in the measuring path measured by the measuring means. It is characterized by comprising a display means for displaying the tension measurement value of the above. At this time, the state in which knitting can be performed means a state in which the knitted fabric can be knitted as it is if it is guided to the knitting needle after passing through the yarn feeder.

Further, a tension applying means for applying tension to the knitting yarn is provided in the yarn feeding path. Then, the display means is measured so as to be comparable to the tension target value of the knitting yarn after passing through the yarn feeder, which is targeted in advance, and to be brought closer to the tension target value by adjusting the tension applying means. The tension measurement value of the knitting yarn in the path may be displayed.

Further, the yarn feed rate of the knitting yarn in the measurement path is changed according to the yarn feed rate that varies depending on the change in the feed direction of the knitting yarn in the yarn feed path at the position after passing through the yarn feeder. May be good.

Further, the tension measuring device main body may be detachably installed in the vicinity of the yarn feeding port of the knitting machine.

Further, in order to achieve the above object, in the present invention, as a method for measuring the tension of the knitting machine, the knitting yarn that has passed through the yarn feeding path to the knitting needle in a state where the tension is applied to the knitting yarn from the yarn package is the yarn feeding path. It is assumed that the knitting machine is guided by the yarn feeding port and is fed to the knitting needle. Then, the knitting yarn is pulled in at a position after passing through the yarn feeding port in a state where knitting can be performed with respect to a measurement path different from the yarn feeding path to the knitting needle. Then, the tension of the knitting yarn drawn into the measuring path without knitting is measured, and the tension measurement value of the knitting yarn is displayed at a position after passing through the yarn feeding port.

As described above, by pulling the knitting yarn into the measurement path in a state where the knitting yarn can be knitted at the position after passing through the yarn feeder and measuring the tension of the knitting yarn, the tension of the knitting yarn can be knitted at the position after passing through the yarn feeder. It is possible to accurately grasp the thread feeding route in a state where it can be performed. In particular, even in the case of intarsia knitting in which a knitted fabric is knitted from a yarn package via a plurality of yarn feeding paths having different lengths, the knitting yarn is knitted at a position after passing through the yarn feeding port for each yarn feeding path. The tension can be grasped accurately. Further, it is possible to accurately grasp the tension of the knitted yarn that fluctuates according to the knitting amount (thread amount) of the knitted fabric even if the yarn feeding path is the same.

Moreover, the tension of the knitting yarn is measured by pulling the knitting yarn into a measurement path different from the yarn feeding path to the knitting needle with the yarn feeding port stopped at the position after passing through the yarn feeding port to measure the tension. It is not necessary to knit the knitted fabric with a knitting needle during the process, and it is possible to confirm the defect of the knitted fabric due to the abnormality of the tension measurement value of the knitted yarn before knitting and prevent it.

Further, by displaying the tension measurement value of the knitting yarn in the measurement path so as to be comparable to the tension target value of the knitting yarn to be targeted in advance and to be closer to the tension target value by adjusting the tension applying means, the tension is applied. By means, the tension applied to the knitting yarn can be adjusted so that the measured tension value accurately approaches the target tension value.

In addition, by changing the yarn feed rate of the knitting yarn in the measurement path according to the yarn feed rate that fluctuates due to the change of the yarn feed direction of the yarn feed path at the position after passing through the yarn feed port, the yarn feed path can be changed. The tension corresponding to the fluctuating yarn feed rate of the knitting yarn can be easily measured in the measurement path.

Furthermore, by installing the tension measuring device main body in the vicinity of the yarn feeding port of the knitting machine in a detachable manner, it can be installed in the vicinity of the yarn feeding port of other knitting machines, and a single tension measuring device is used. It is possible to accurately measure the tension of the knitting yarn in the yarn feeding path of another knitting machine.

In addition, the tension measurement value of the knitting yarn drawn into the measurement path different from the yarn feeding path to the knitting needle in a state where the knitting yarn can be knitted at the position after passing through the yarn feeder, and drawn into the measurement path without knitting. it's shown. As a result, in addition to being able to accurately grasp the tension of the knitting yarn that is knitted at the position after passing through the yarn feeding port, problems with the knitted fabric due to abnormal tension of the knitting yarn in the yarn feeding path can occur before knitting. It is possible to provide a tension measuring method that can be prevented.

When the yarn carriers 15 and 16 are carried by the carriage 12 and slide in the left-right direction, the yarn carriers 20 are pulled out from the yarn feeders 153 and 163 in the same guiding direction as the knitting yarn 20 from the side tension device 4. It can be switched between the guiding direction and the pushing direction of pulling out in the opposite direction.

FIG. 3 shows a schematic configuration diagram of the tension measuring device of FIG. In FIG. 3, in the vicinity of the yarn feeding port 153 of the yarn carrier 15, the yarn feeding port 153 is stopped at a position after passing through the yarn feeding port 153 to a measurement path 24 different from the yarn feeding path 2 to the knitting needle. The tension measuring device main body 50 of the tension measuring device 5 for pulling in while holding and measuring the tension is installed. The tension measuring device main body 50 includes a frame-shaped housing 59, a magnet (not shown) is provided on the lower surface of the housing 59, and the tension measuring device main body 50 can be freely attached to and detached from the metal support 19 of the flat knitting machine 1. It is attached to. As a result, it can be installed near the yarn feed port of another flat knitting machine, and the tension of the knitting yarn in the yarn feeding path of the other flat knitting machine can be accurately measured by using a single tension measuring device main body 50. Can be measured. In the present embodiment, the housing 59 of the tension measuring device main body 50 is detachably mounted on the support base 19 of the flat knitting machine 1, but the tension measuring device main body cannot be attached to or detached from the support base of the flat knitting machine. It may be provided integrally in a state.

The tension measuring device main body 50 includes a knitting yarn pulling means 51 that pulls the knitting yarn 20 into the measuring path 24 in a state where knitting can be performed in the yarn feeding path 2 when the knitting yarn 20 is fed to the knitting needle at a position after passing through the yarn feeding port 153. There is. The knitting yarn pulling means 51 sandwiches the knitting yarn 20 with respect to the knitting yarn pulling motor 511, the knitting yarn pulling pulley 513 rotationally and integrally connected to the output shaft 512 of the knitting yarn pulling motor 511, and the knitting yarn pulling pulley 513. It is equipped with a driven pulley 514 that goes around in a state. In this case, the yarn feed rate of the knitting yarn 20 in the measuring path 24 by the knitting yarn pulling means 51 is guided to the knitting needle at the position after passing through the yarn feeder port 153 by the yarn carrier 15 carried by the carriage 12. It is set to be the same as the yarn feed rate of the knitting yarn 20 in.

Further, the tension measuring device main body 50 includes a measuring means 52 provided between the yarn feeding port 153 and the knitting yarn pulling means 51 of the measuring path 24. The measuring means 52 includes two guide rollers 521 and 522 that guide the knitting yarn 20 fed to the measuring path 24, a tension detecting roller 523 provided between the guide rollers 521 and 522, and a tension detecting roller 523. It is equipped with a load cell 524 to support. Then, the measuring means 52 makes the tension of the knitting yarn 20 drawn into the measuring path 24 by the knitting yarn drawing means 51 measured by the load cell 524 via the tension detection roller 523.

Further, the tension measuring device main body 50 includes a monitor 53 as a display means for displaying the tension measured value measured by the load cell 524. The monitor 53 displays the tension measurement value of the knitting yarn 20 at the position after passing through the yarn feeding port 153, that is, the tension measurement value of the knitting yarn 20 in the measurement path 24. The tension measurement value displayed on the monitor 53 is displayed so as to be comparable to the pre-targeted tension target value of the knitting yarn 20 up to the knitting needle in the yarn feeding path 2, and is displayed on the top spring device 3 and the side. By adjusting the tension device 4, the measured tension value is used so as to approach the tension target value of the knitting yarn 20 in the yarn feeding path 2 at the position after passing through the yarn feeding port 153. In this case, the tension target value of the knitting yarn 20 in the yarn feeding path 2 at the position after passing through the yarn feeding port 153 is preset according to the model of the flat knitting machine, and is an ideal tension target value. It suffices as long as it is a tension target value that is not necessary and can be knitted without difficulty.

Further, the yarn feed rate of the knitting yarn 20 in the measurement path 24 is a change in the guiding direction of the knitting yarn 20 to the knitting needle in the yarn feeding path 2 at the position after passing through the yarn feeding port 153, that is, in the traveling direction of the carriage 12. The yarn feed speed is changed according to the yarn feed rate that fluctuates when the knitting yarn 20 from the yarn feeding port 153 of the yarn carrier 15 that is reversed by switching the folding back is switched between the pushing direction and the pulling direction. The yarn feed speed that fluctuates when the knitting yarn 20 is switched between the pushing direction and the pulling direction is the pitch in the course direction of the stitch, the loop length of the stitch to be knitted, the speed at which the knitted fabric 22 is knitted, and the flat knitting machine 1. It is preset according to the gauge of. In this case, the yarn feed speeds in the pushing direction and the pulling direction of the knitting yarn 20 are preset for each model of the flat knitting machine 1.

For example, in the case of a plain structure, the yarn feed rate (m / s) in the pushing direction of the knitting yarn 20 is determined.
((Crop length of stitches-Pitch of stitches) / Pitch of stitches) × Speed of knitting the knitted fabric 22
It is also possible to calculate based on. Specifically, the yarn feed rate (m / s) in the pushing direction of the knitting yarn 20 is the pitch of 1.814 in the course direction of the stitch, the loop length of the stitch to be knitted 6.0, and the speed at which the knitted fabric 22 is knitted. 1.0, according to the gauge 14G of the flat knitting machine 1
((6.0-1.814) /1.814) × 1.0≈2.3 m / s .

On the other hand, the yarn feed rate (m / s) in the pulling direction of the knitting yarn 20 is
((Loop length of stitch + pitch of stitch) / Pitch of stitch) × Speed to knit the knitted fabric 22
It is also possible to calculate based on. Specifically, the yarn feed rate (m / s) in the pulling direction of the knitting yarn 20 is the pitch of 1.814 in the course direction of the stitch, the loop length of the stitch to be knitted 6.0, and the speed at which the knitted fabric 22 is knitted. 1.0, according to the gauge 14G of the flat knitting machine 1
((6.0 + 1.814) /1.814) × 1.0≈4.3 m / s .

It is also possible to obtain the rotation speed of the knitting yarn pulling motor 511 from the mutual correlation based on the yarn feeding speed in the pushing direction or the pulling direction of the knitting yarn 20. For example, at a yarn feed rate of 2.3 m / s in the pushing direction of the knitting yarn 20, the rotation speed of the knitting yarn pull-in pulley 513 is about 1400 rpm, and at a yarn feeding speed of 4.3 m / s in the pulling direction of the knitting yarn 20. It is obtained from the mutual correlation that the rotation speed of the knitting yarn pull-in pulley 513 is about 2550 rpm.

Next, an example of a measuring method for measuring the tension of the knitting yarn 20 at a position after passing through the yarn feeding port 153 using the tension measuring device main body 50 will be described.

First, the knitting yarn 20 at the position after passing through the yarn feeding port 153 of each yarn carrier 15 from the yarn package 17 via the crown spring device 3 and the side tension device 4 is measured in a measurement path 24 different from the yarn feeding path 2 to the knitting needle. It is pulled in in a state where it can be organized.

Next, the knitting yarn 20 drawn into the measurement path 24 without knitting is sandwiched between the knitting yarn pull-in pulley 513 and the driven pulley 514. Then, the knitting yarn pull-in pulley 513 is rotated by the knitting yarn pull-in motor 511 in a state where knitting can be performed in the yarn supply path 2 when guiding the knitting needle, and the driven pulley 514 is rotated around to knit into the measurement path 24. The knitting yarn 20 pulled in without doing this is fed.

At this time, when setting the yarn feed rate that fluctuates when the knitting yarn 20 of the yarn feeding path 2 is switched between the pushing direction and the pulling direction at the position after passing through the yarn feeding port 153, the yarn feeding speed is set in the course direction of the stitch. The yarn feed rate in the measurement path 24 may be set based on a preset numerical value according to the pitch, the loop length of the stitch to be knitted, the speed at which the knitted fabric 22 is knitted, the gauge of the flat knitting machine 1, and the like. .. Specifically, the rotation speed of the knitting yarn pull-in pulley 513 may be set based on the correlation with the yarn feeding speed in the pushing direction or the pulling direction of the knitting yarn 20. As a result, the yarn feeding speeds in the pushing direction and the pulling direction, which have different ratios depending on the combination of the loop length of the stitch and the knitting speed, are easily reproduced, and the tension according to the yarn feeding speed fluctuating in the yarn feeding path 2 is measured in the measuring path 24. Can be easily measured even in.

Then, the tension of the knitting yarn 20 drawn into the measuring path 24 at the position after passing through the yarn feeding port 153 without knitting is measured by the load cell 524 of the measuring means 52. As a result, the tension of the knitting yarn 20 at the position after passing through the yarn feeding port 153 can be accurately grasped as well as the yarn feeding path 2 in a state where knitting can be performed. In particular, even in the case of intarsia knitting in which the knitted fabric 22 is knitted from different yarn packages 17 via a plurality of yarn feeding paths 2 and 2 having different lengths, the yarn feeding port is used for each of the individual yarn feeding paths 2 and 2. The tension of the knitting yarn 20 at the position after passing through 153 can be accurately grasped. Further, even if the yarn feeding path 2 is the same, the tension of the knitting yarn 20 that varies depending on the knitting amount of the knitted fabric 22 can be accurately grasped. Moreover, the knitting yarn 20 is pulled into the measurement path 24 different from the yarn feeding path 2 to the knitting needle at the position after the yarn feeding port 153 has passed, while the yarn feeding port 153 is stopped, and the tension is measured. It is not necessary to knit the knitted fabric 22 while measuring the tension of the knitting yarn 20, and it is possible to confirm the defect of the knitted fabric 22 due to the abnormality of the tension measurement value of the knitting yarn 20 before knitting and prevent it. ..

Then, the tension measurement value of the knitting yarn 20 measured by the load cell 524 at the position after passing through the yarn feeding port 153 is displayed on the monitor 53. Therefore, the tension measurement value displayed on the monitor 53 can be compared with the tension target value of the knitting yarn 20 in the yarn feeding path 2 at the position after passing through the yarn feeding port 153. As a result, the load of the tension disk 31 is adjusted by the adjustment knob 34 of the ceiling spring device 3, and the swing load of the side tension arm 42 with respect to the thread stand 18 is adjusted by the support portion 41 of the side tension device 4. , The tension measurement value of the knitting yarn 20 in the yarn feeding path 2 can be accurately approached to the tension target value.

The present invention is not limited to the above embodiment, and includes various other modifications. For example, in the above embodiment, the tension measurement value displayed on the monitor 53 can be compared with the tension target value in the thread feeding path 2 at the position after passing through the thread feeding port 153, and the ceiling spring device 3 and the side tension device 4 can be compared. It was used to bring the tension measurement value closer to the tension target value by making adjustments such as, but it is sufficient if the tension of the knitting yarn drawn into the measurement path at the position after passing through the yarn feeder is displayed on the monitor as the tension measurement value. At this time, since the tension measurement value displayed on the monitor is as close as possible to the state in which knitting is performed, it is not always necessary to adjust the tension value of the knitting yarn to approach the tension target value. From this point, the tension measurement value displayed on the monitor makes it possible to grasp the difference between each yarn feeder in the same knitting machine and the difference between different knitting machines, and it is also possible to adjust the tension applied state in the yarn feeder path. It is possible to deal accurately based on the tension measurement value without relying on it.

Further, in the above-described embodiment, the feed roller 44 that applies a driving force to the knitting yarn 20 is provided in the yarn feeding path 2, but the yarn feeding amount of the knitting yarn is measured while applying the driving force to the knitting yarn. The delivery device may be provided in the yarn feeding path.

Further, in the above-described embodiment, the case where the tension measuring device 5 is applied to the flat knitting machine 1 has been described, but the present invention is not limited to this, and the tension measuring device is a knitting machine such as a warp knitting machine or a circular knitting machine. Needless to say, it may be applied to.

Further, in the above-described embodiment, the case where the ceiling spring device 3 and the side tension device 4 are applied as the tension applying means has been described, but these are only examples, and the tension applying means is not limited thereto. ..
