YF is supplied with a knitting yarn from a knitting supply source such as a cone in which the knitting yarn is wound. When the YF moves, the knitting yarn is pulled on the YF to release the knitting yarn from the cone. In order to improve the quality of the knitted fabric, it is required that an appropriate tension (set tension) acts on the knitting yarn when the knitted fabric is knitted. However, there are cases where the tension of the knitting yarn becomes inadequate depending on the type of knitting yarn and its condition, external factors such as humidity and temperature, or knitting conditions such as knitting speed and knitting operation. Conventionally, the measurement and adjustment of the tension of the knitting yarn is performed upstream of the knitting path away from the needle bed gap where knitting is now performed, and it is difficult to quickly detect the tension change of the knitting yarn in the vicinity of the needle bed gap. Also, the tension adjustment tends to be delayed.

The present invention has been made in consideration of the above circumstances, and one of the objects of the present invention is to provide a flat knitting machine capable of quickly and accurately measuring the tension of the knitting yarn during knitting.

The flat knitting machine of the present invention,

A needle bed having a plurality of needles, a yarn feeder attached to a rail parallel to the length of the needle bed and traveling along the rail, and yarn knitting yarn to the needle bed gap of the needle bed; In the flat knitting machine provided with the knitting condition adjusting apparatus to adjust, and the knitting condition control part which controls the said knitting condition adjusting apparatus based on the tension of the said knitting yarn,

The yarn feeder includes a tension sensor that acquires information correlated with the tension of the knitting yarn and outputs the information to the knitting condition controller.

As one form of the flat knitting machine of this invention,

The tension sensor,

A guide shaft extending in the thickness direction of the yarn feeder and configured to be displaceable in a direction crossing the thickness direction of the yarn feeder, the guide shaft portion of which the knitting yarn is guided on a circumferential surface thereof;

The form which outputs the degree of displacement of the said guide shaft part to the said knitting condition control part is mentioned.

As one form of the flat knitting machine of this invention,

The knitting condition adjusting device may be a tension adjusting device which is mounted on the yarn feeder and acts on an upstream side portion of the knitting yarn to adjust the tension of the knitting yarn.

As one form of the flat knitting machine of this invention provided with the said tension adjusting device,

The yarn feeder includes a carrier portion attached to the rail and a drooping portion extending downward from the carrier portion and having a narrower width than the carrier portion,

The said tension adjusting device is a form provided in the position of the side of the said lower part, when the said yarn feeder is seen from the front from the direction orthogonal to the said rail.

As one form of the flat knitting machine of this invention provided with the said tension adjusting device,

The knitting condition controller for controlling the tension adjusting device may be mounted on the yarn feeder.

As one form of the flat knitting machine of this invention provided with the said tension adjusting device,

The tension adjusting device may be in the form of adjusting the tension of the knitting yarn by acting in a direction orthogonal to the thickness direction of the yarn feeder with respect to the knitting yarn.

According to the flat knitting machine of the present invention having a tension sensor in the yarn feeder (hereinafter referred to as YF), the tension of the knitting yarn in the knitting yarn can be confirmed because the tension of the knitting yarn can be confirmed at a position near the knitting yarn near the needle bed gap. Can be measured quickly and accurately. Therefore, the knitting conditions according to the tension of the knitting yarn can be adjusted at a timing earlier than before. As the knitting condition adjusting device for adjusting the knitting conditions, a tension adjusting device for acting on the knitting yarn to adjust the tension of the knitting yarn, a feeding device for actively adjusting the feeding amount of the knitting yarn, and a cam for adjusting the pulling amount of the knitting yarn by knitting needles Systems, and the like. In any configuration, the tension of the knitting yarn can be changed, and the knitting tension in the knitting growth center can be easily maintained optimally, thereby improving the quality of the knitting fabric.

If the guide shaft portion is a guide shaft portion extending in the thickness direction of YF, twisting or the like is unlikely to occur in the knitting yarn from the introduction guide to the guide shaft portion. In addition, since the guide shaft portion is configured to be displaced in a direction crossing the thickness direction of the YF, the guide shaft portion does not protrude in the thickness direction of the YF when the guide shaft portion is displaced. Can be avoided.

By providing the tension adjusting device, which is a kind of knitting condition adjusting device, in YF, it is possible to optimize the knitting tension in response to the change in the tension of the knitting yarn at the position near the needle bed gap.

Since a plurality of YFs are arranged in the flat knitting machine and are concentrated in a narrow space near the needle bed gap, there is no idea of providing a tension adjusting device at a position near the tip of the YF. On the other hand, in the flat knitting machine of this invention, in view of the subject of this invention, the tension adjusting apparatus is provided in the position of YF. When the number of YFs increases, the tension adjusting device may hinder the movement of the YF. However, the problem can be solved by providing the tension adjusting device at a position on the side of the lower part of the YF.

By providing the knitting condition control unit in the YF, the information obtained from the tension sensor can be used for controlling the tension adjusting device without transmitting the information outside the YF.

By setting the direction of action of the tension adjusting device in the direction orthogonal to the thickness direction of the YF (that is, the plane direction of the YF), the tension adjusting device can be prevented from protruding largely from the YF.

The introduction guide 21 is provided in the part which extends in the extending direction of the rail 1R and protrudes from the lower part 2b among the small pieces fixed to the lower part 2b. In addition, the introduction guide 21 is not limited to a roller, For example, it may be a cylindrical member which can insert the knitting yarn 9 and let it pass.

The lower mounting portion 2L is attached to a position below the introduction guide 21. In the drawing, the lower mounting portion 2L is seen as a plate member, but is actually configured by combining plank pieces, aggregates and the like. The lower mounting portion 2L is for installing electrical devices such as the tension sensor 4 and the tension adjusting device 5 shown in Fig. 3 and is made of an insulating material. A part of the lower mounting part 2L protrudes to the side of the main body part 2M when the YF 2A is viewed from the front in a direction orthogonal to the stretching direction of the rail 1R, and the rear side of the protruding part thereof (Fig. 3), the tension sensor 4 or the tension adjusting device 5 is provided.

The upper mounting part 2U is a plate-shaped member provided on the surface side (side of FIG. 2) of the carrier part 2a. The upper mounting portion 2U is for providing the control circuit 20 and the like described later, and is made of an insulating material. The surface side of the carrier part 2a may be formed in a box shape, and the upper mounting part 2U may be accommodated inside the carrier part 2a. In this case, if a lid is provided in the carrier part 2a, the control circuit 20 can be protected from dust and oil.

≪Feed part≫

The power supply unit 3 supplies electric power to the control circuit 20, the tension sensor 4, and the tension adjusting device 5 described later. The power supply unit 3 may be an active power supply that supplies electric power by a magnetic force such as a battery, or may be a passive power supply that receives power from the outside of the YF 2A and supplies the power to the control circuit 20 or the like. good. As a power supply method for a passive power supply, the contact-type power supply method as described in patent documents 1, 2, the non-contact power supply method using electromagnetic induction, etc. are mentioned, for example.

`` Control circuit ''

The control circuit 20 is provided on the surface side of the upper mounting portion 2U and is electrically connected to the power feeding portion 3. In the present example, the tension adjusting device 5 is provided at the YF 2A, and the control circuit 20 of the present example controls the tension adjusting device 5 based on the information from the tension sensor 4. (Composition condition control unit). In addition, the YF 2A of this example may be equipped with the transceiver as mentioned later, and the communication control part of a transceiver can be provided in the control circuit 20 in this case. Each control part provided in these YF 2A is controlled by the integrated control part with which the computer 10 of the flat knitting machine 1 is equipped.

≪Tension sensor≫

The tension sensor 4 is provided in the lower mounting portion 2L of the YF 2A, acquires information of the physical quantity correlated with the tension of the knitting yarn 9, and outputs the information to the control circuit 20 as an electric signal. do. By providing the tension sensor 4 in the YF 2A, the relaxation and the tension of the knitting yarn 9 can be grasped faster than before. The physical quantity to be acquired is not particularly limited as long as it is a physical quantity that changes in correlation with the change in the tension of the knitting yarn 9.

In the description of the tension sensor 4 in this example, FIGS. 4 and 5 are referred to. As shown in Fig. 4, the tension sensor 4 is located on the downstream side of the dispensing direction of the knitting yarn 9 (in the feed yarn 2f side of the main body 2M of Fig. 2, Fig. 3) from the introduction guide 21. It is provided and contacts the knitting yarn 9, and acquires the physical quantity according to the stress which the knitting yarn 9 receives. More specifically, the tension sensor 4 is comprised from the guide rollers 41 and 42 and the guide shaft part 40 attached in the inclination to the position between the guide rollers 41 and 42. As shown in FIG. The tension of the knitting yarn 9 passing between the guide rollers 41 and 42 is measured by the guide shaft portion 40. The guide shaft part 40 is comprised so that it may displace to the left-right direction of the paper surface, and acquires the deformation amount according to the displacement amount as said physical quantity.

The structure of the guide shaft part 40 is demonstrated in detail based on FIG. The guide shaft part 40 of this example is equipped with the roller 4r, and the roller 4r is the roller support shaft 4b extended in the direction along the left-right direction (stretching direction of the rail 1R of FIG. 3) of the paper. It is supported so that it can rotate at the tip. The rear end of the roller support shaft 4b is fitted to the pair of wall portions 4w, so that the roller support shaft 4b can be displaced in the horizontal direction of the paper. The groove part 4g orthogonal to the axial direction of the roller support shaft 4b is formed in the upper surface of the intermediate part of this roller support shaft 4b, and the small piece 4p is fitted in the groove part 4g. In the small piece 4p, the edge part on the opposite side to the groove part 4g is supported by the deformation sensor 4s. Therefore, when the tension of the knitting yarn 9 acts and the roller support shaft 4b which supports the guide shaft part 40 is displaced, the small piece 4p will be pressed by the groove part 4g, and it will bend. The deformation sensor 4s detects the deformation amount of the small piece 4p generated by the bending. Of course, the small piece 4p itself may be comprised by a deformation sensor. The configuration of the tension sensor 4 described above is merely an example, and the measurement of tension may be realized by other detection principles.

Information of the physical quantity (deformation amount in this example) acquired by the tension sensor 4 is input to the control circuit 20 of FIG. The control circuit 20 controls the tension adjusting device 5 based on the information. In the adjustment of the tension of the knitting yarn 9, the control circuit 20 refers to, for example, a look up table stored in the memory of the control circuit 20. As a look-up table, what shows the correlation between the said physical quantity and the tension of the knitting yarn 9 is mentioned. The control circuit 20 compares the obtained tension of the knitting yarn 9 with the set tension stored in the memory and operates the tension adjusting device 5 so that the tension of the knitting yarn 9 approaches the set tension. For example, when the obtained tension is lower than the set tension, the tension adjusting device 5 is operated so that the tension of the knitting yarn 9 becomes high. On the contrary, when the tension obtained is higher than the set tension, the tension adjusting device 5 is operated so that the tension of the knitting yarn 9 is lowered. By repeating the operation of the tension adjusting device 5 and the comparison of the measurement in the tension sensor 4 and the tension in the control circuit 20, the tension of the knitting yarn 9 is made closer to the set tension.

≪Tension adjuster≫

As shown in FIG. 4, the tension adjusting device 5 in this example acts on a portion passing between the introduction guide 21 and the tension sensor 4 in the knitting yarn 9 to adjust the tension of the knitting yarn 9. do. This tension adjusting device 5 is a knitting condition adjusting device which directly acts on the knitting yarn 9 and adjusts the tension itself of the knitting yarn 9 which is a knitting condition, thereby optimizing the tension of the knitting yarn 9. The tension adjusting device 5 does not necessarily need to be provided at the YF 2A, and may be provided at the position of the side tension of the flat knitting machine 1 of FIG. However, adjusting the knitting yarn 9 at a position close to the needle bed gap like the tension adjusting device 5 of the present example is preferable because the tension of the knitting yarn 9 can be adjusted quickly. The tension adjusting device 5 of this example is provided at a position on the side of the lower part 2b when the YF 2A is viewed from the front in a direction orthogonal to the rail 1R. Therefore, the tension adjusting device 5 does not interfere with the member (for example, YF of another rail) in the vicinity of the running route of the YF 2A. In addition, since the tension adjusting apparatus 5 of this example is comprised so that the width | variety of the carrier part 2a in the extending | stretching direction of the rail 1R may not protrude, the YF (2A, 2B) of FIG. You can also make them side by side. In the case where the tension adjusting device 5 is provided outside the YF 2A, it is necessary to allow the information acquired by the tension sensor 4 to be transmitted to the outside of the YF 2A.

The tension adjusting device 5 of this example includes a floating stationary piece 51 fixed to the lower mounting portion 2L and a movable piece moving in a straight line in a direction close to and away from the stationary piece 51. The tension of the knitting yarn 9 is adjusted by sandwiching the knitting yarn 9 between the two pieces 50. The movable piece 50 can be configured to operate by a solenoid or the like, and the knitting piece 9 is sandwiched between the stationary piece 51 and the movable piece 50 by varying the amount of current supplied to the solenoid. You can change the power. If the knitting force of the knitting yarn 9 is strong, the knitting yarn 9 becomes difficult to move, and the tension of the knitting yarn 9 on the downstream side becomes higher than the tension adjusting device 5. On the contrary, when the force for sandwiching the knitting yarn 9 is weak, the knitting yarn 9 is easy to move, and the tension of the knitting yarn 9 on the downstream side is lower than the tension adjusting device 5. The linearly moving direction of the movable piece 50 described above, that is, the action direction of the tension adjusting device 5 with respect to the knitting yarn 9 is perpendicular to the thickness direction of the YF 2A, that is, the main body of the YF 2A. It is a direction parallel to the plane direction of the part 2M. Therefore, even when the movable piece 50 operates, the movable piece 50 does not protrude in the thickness direction of the YF 2A, and the member of the movable piece 50 is in the vicinity of the running route of the YF 2A. Do not interfere with

≪Others≫

The YF 2A communicates information with the computer 10 of the flat knitting machine 1 of FIG. 1 in order to realize the tension of the knitting yarn 9 according to the kind of the knitting yarn 9 and the knitting structure of the knitting fabric to be knitted. It is preferable to comprise so that exchange is possible. For example, it is possible to provide a transceiver such as an optical wireless system in the YF 2A so that information can be transmitted and received between the control circuit 20 and the computer 10 of the YF 2A. The transceiver can be installed on the control circuit 20 and can be controlled by the communication control unit provided in the control circuit 20. In the control circuit 20, the selection of the information to be transmitted and the selection of the received information can be made.

Embodiment 2

The tension adjusting device 5 may be any one capable of varying the tension of the knitting yarn 9. For example, the tension adjusting device 5 includes a configuration in which a pair of comb-like members are arranged such that comb teeth alternately engage with each other. In this case, the tension of the knitting yarn 9 can be changed by arranging the knitting yarn 9 so as to pass between adjacent comb teeth, and changing the spacing of both comb-shaped members in the thickness direction of the comb-like member.

Embodiment 3

The knitting condition adjusting device in the present invention is not limited to the tension adjusting device 5. As long as the tension of the knitting yarn 9 can be optimized as a result of changing certain conditions relating to knitting, it can be set as the knitting condition adjusting apparatus of the present invention. For example, if it is a flat knitting machine 1 provided with the feeding device which pinches the knitting yarn 9 to a pair of rollers which at least one rotationally drives, and actively feeds the knitting yarn 9 by rotation of a roller, the feeding will be carried out. The apparatus and the sending control unit controlling the apparatus can be set as the knitting condition adjusting apparatus and the knitting condition controlling unit, respectively. In this case, the tension of the knitting yarn 9 can be optimized by adjusting the feeding amount of the knitting yarn 9 based on the information about the tension from the tension sensor 4. In the feeding device, the tension of the knitting yarn 9 can be relaxed by increasing the number of rotations of the rollers and increasing the feeding amount of the knitting yarn 9. In addition, a cam system for adjusting the amount of pull of the knitting yarn 9 according to the knitting needle and a cam control unit for controlling the same may be set as the knitting condition adjusting device and the knitting condition control unit, respectively. In this case, the tension of the knitting yarn 9 can be optimized by adjusting the drawing amount of the knitting needle based on the information on the tension from the tension sensor 4.

It is also included in adjusting the knitting conditions to promote the user to change the knitting conditions in order to optimize the tension of the knitting yarn 9. For example, a tension abnormality notification device such as a display or an alarm lamp which notifies the user of an abnormality in tension and a notification control unit for controlling the same can be set as the knitting condition adjusting device and the knitting condition controlling device, respectively. When the notification is made, the integrated control unit of the flat knitting machine 1 may determine that the knitting operation is stopped once.
