Definitions

the present invention relates to a flat knitting machine.
a flat knitting machine includes a needle bed in which multiple knitting needles are arranged side-by-side, and is provided with yarn feeders (hereinafter, sometimes called "YF") that are attached to a rail, travel along the rail, and feed knitting yarn to the knitting needles of the needle bed.
yarn feeders hereinafter, sometimes called "YF"
Patent Document 1 discloses a configuration in which a YF is driven by a linear motor, or a drive motor or the like is attached to a YF, such that the YF is self-propelled.
the drive motor provided for the YF and the control apparatus for control thereof are supplied with electrical power through contact power supply that is performed via a contact strip provided on the rail.
Patent Document 2 discloses a moving body (reference sign 300 in Patent Document 2) that travels on a rail to which the YF is attached, and that moves the YF by inserting a changeover pin into the YF.
the insertion and removal of the changeover pin is performed using electrical power that is supplied to the moving body through contact between a conductive sheet provided on the rail and a carbon brush provided on the moving body.
Each YF receives a supply of knitting yarn from a knitting yarn supply source such as a cone around which the knitting yarn is wound.
a knitting yarn supply source such as a cone around which the knitting yarn is wound.
the knitting yarn is pulled by the YF and fed out from the cone.
appropriate tension set tension
the tension of the knitting yarn becomes inappropriate due to the type of knitting yarn and state thereof, external factors such as humidity and temperature, and knitting conditions such as knitting speed and knitting operations.
knitting yarn tension has been measured and adjusted at a position that is upstream in the knitting yarn path and separated from the needle bed gap where knitting is currently being performed, and therefore it has been difficult to speedily detect changes in the knitting yarn tension in the vicinity of the needle bed gap, and adjustment of the tension tends to be delayed.
the present invention was achieved in light of the foregoing circumstances, and an object thereof is to provide a flat knitting machine in which knitting yarn tension can be speedily and accurately measured during knitting.
a flat knitting machine of the present invention includes: a needle bed having a plurality of knitting needles; a yarn feeder that is attached to a rail that is parallel to a length direction of the needle beds, the yarn feeder travelling along the rail and feeding knitting yarn to a needle bed gap of the needle beds; a knitting condition adjustment apparatus that adjusts a knitting condition related to yarn feeding; and a knitting condition control unit that controls the knitting condition adjustment apparatus based on a tension of the knitting yarn, wherein 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 control unit.
the tension sensor includes a guide shaft portion that extends in a thickness direction of the yarn feeder and is configured to be displaceable in a direction intersecting the thickness direction of the yarn feeder, the knitting yarn being guided on a circumferential surface of the guide shaft portion, and the tension sensor outputs an extent of displacement of the guide shaft portion to the knitting condition control unit.
the knitting condition adjustment apparatus is a tension adjustment apparatus that is provided on the yarn feeder and adjusts the tension of the knitting yarn by acting on a portion of the knitting yarn that is upstream of the tension sensor.
the yarn feeder includes a carrier portion that is attached to the rail, and a suspended portion that extends downward from the carrier portion and has a smaller width than the carrier portion, and the tension adjustment apparatus is provided at a position on a lateral side of the suspended portion in a front view of the yarn feeder from a direction orthogonal to the rail.
the knitting condition control unit for controlling the tension adjustment apparatus is provided on the yarn feeder.
the tension adjustment apparatus adjusts the tension of the knitting yarn by acting on the knitting yarn in a direction orthogonal to a thickness direction of the yarn feeder.
the tension of the knitting yarn can be checked at a position near the knitting location in the vicinity of the needle bed gap, thus making it possible to speedily and accurately measure changes in the tension of the knitting yarn at the knitting location. It is therefore possible to adjust a knitting condition in accordance with the tension of the knitting yarn at an earlier timing than in conventional technology.
the knitting condition adjustment apparatus that adjusts the knitting condition include a tension adjustment apparatus that adjusts the tension of the knitting yarn by acting on the knitting yarn, a feeding apparatus that dynamically adjusts the feeding amount of the knitting yarn, and a cam system that adjusts the amount of the knitting yarn that is pulled by the knitting needle. In all of these configurations, it is possible to change the tension of the knitting yarn, it is easier to maintain an optimum tension of the knitting yarn at the knitting location, and it is possible to improve the quality of the knitted fabric.
the guide shaft portion is a guide shaft portion that extends in the thickness direction of the YF, the knitting yarn is not likely to become twisted or the like between the introduction guide and the guide shaft portion.
the guide shaft portion is configured to be displaceable in a direction intersecting the thickness direction of the YF, and therefore the guide shaft portion does not protrude beyond the YF in the thickness direction during displacement of the guide shaft portion, thus making it possible to avoid a fault such as the guide shaft portion coming into contact with another YF.
the tension adjustment apparatus which is one type of knitting condition adjustment apparatus, being provided on the YF, it is possible to immediately respond to a change in the tension of the knitting yarn at a position in the vicinity of the needle bed gap and optimize the tension of the knitting yarn.
the tension adjustment apparatus is intentionally provided at the YF position.
Providing the knitting condition control unit on the YF makes it possible for the information acquired by the tension sensor to be used in control of the tension adjustment apparatus without being transmitted from the YF to the outside.
the direction in which the tension adjustment apparatus acts is a direction orthogonal to the thickness direction of the YF (i.e., the planar direction of the YF), it is possible to suppress the case where the tension adjustment apparatus protrudes a large amount from the YF.

More specifically, the main body portion 2M is divided into a carrier portion 2a on which the traveling rollers 2r are provided, and a suspended portion 2b that extends so as to hang downward from the carrier portion 2a. In order to ensure strength, the main body portion 2M is preferably made of a metal. A pin groove 2h for receiving the changeover pin of the selector 1S shown in FIG. 1 is provided in the upper edge of the carrier portion 2a.

the introduction guide 21 of this embodiment is configured by a roller that has a rotation shaft that extends in the thickness direction of the main body portion 2M.
the introduction guide 21 is provided on a small piece that extends in the extending direction of the rail 1R and is fixed to the suspended portion 2b, and more specifically in a portion of the small piece that projects out from the suspended portion 2b.
the introduction guide 21 is not limited to being a roller, and may be a tubular member through which the knitting yarn 9 can pass, for example.
the lower mounting portion 2L is attached at a position that is below the introduction guide 21.
the lower mounting portion 2L appears to be a plate-shaped member in the drawings, it is actually constituted by combining a plate piece and a framework member or the like.
This lower mounting portion 2L is for the mounting of electrical devices such as a tension sensor 4 and a tension adjusting apparatus 5 that are shown in FIG. 3 , and is made of an insulating material.
a portion of the lower mounting portion 2L projects laterally from the main body portion 2M in a front view of the YF 2A from a direction orthogonal to the extending direction of the rail 1R, and the tension sensor 4 and the tension adjusting apparatus 5 are provided on the back side (side shown in FIG. 3 ) of this projecting portion.

a power supply portion 3 supplies electrical power to a later-described control circuit 20, the tension sensor 4, and the tension adjusting apparatus 5.
the power supply portion 3 may be an active power supply that supplies electrical power from its own power supply, such as abattery, or maybe a passive power supply that receives electrical power from outside of the YF 2A and supplies that electrical power to the control circuit 20 and the like. Examples of methods for supplying electrical power to the passive power supply include a contact type of power supply such as that described in Patent Document 1 or 2, and a contactless power supply method that utilizes electromagnetic induction or the like.
the control circuit 20 is provided on the front side of the upper mounting portion 2U, and is electrically connected to the power supply portion 3.
the tension adjusting apparatus 5 is provided on the YF 2A
the control circuit 20 of this embodiment has a tension control portion (knitting condition control unit) that controls the tension adjusting apparatus 5 based on information from the tension sensor 4.
the YF 2A of this embodiment may include a transceiver as will be described later, and in this case, a communication control portion for the transceiver can be provided in the control circuit 20.
the tension sensor 4 is provided on the lower mounting portion 2L of the YF 2A, acquires information indicating a physical amount that is correlated with the tension of the knitting yarn 9, and outputs the acquired information to the control circuit 20 as an electrical signal. Providing the tension sensor 4 on the YF 2A makes it possible for slack and tension of the knitting yarn 9 to be detected more swiftly than in conventional technology. There are no particular limitations on the acquired physical amount, as long as it changes in correlation with change in the tension of the knitting yarn 9.
FIGS. 4 and 5 will be referenced while describing the tension sensor 4 of this embodiment.
the tension sensor 4 is provided at a position downstream from the introduction guide 21 in the knitting yarn 9 feeding direction (on the side corresponding to the yarn feeding opening 2f of the main body portion 2M in FIGS. 2 and 3 ), is in contact with the knitting yarn 9, and acquires a physical amount that corresponds to stress applied by the knitting yarn 9.
the tension sensor 4 is configured by guide rollers 41 and 42 and a guide shaft portion 40 that is attached in a cantilevered manner at a position between the guide rollers 41 and 42.
the tension of the knitting yarn 9 spanning between the guide rollers 41 and 42 is measured by the guide shaft portion 40.
the guide shaft portion 40 is configured to be displaceable in the left-right direction with respect to the paper plane, and acquires, as the physical amount, a strain amount that corresponds to the amount of displacement.
the guide shaft portion 40 of this embodiment includes a roller 4r, and the roller 4r is rotatably supported at the leading end of a roller support shaft 4b that extends in a direction conforming to the left-right direction with respect to the paper plane (the extending direction of the rail 1R in FIG. 3 ).
the rear end of the roller support shaft 4b is sandwiched by a pair of a wall portions 4w, and the roller support shaft 4b can be displaced in the left-right direction with respect to the paper plane.
a groove portion 4g that extends orthogonal to the axial direction of the roller support shaft 4b is formed in the upper surface of an intermediate portion of the roller support shaft 4b, and a small piece 4p is fitted into the groove portion 4g.
An end portion of the small piece 4p that is on the side opposite to the groove portion 4g is supported by a strain sensor 4s.
the strain sensor 4s detects a strain amount of the small piece 4p caused by the bending.
the small piece 4p itself may be configured by a strain sensor.
the above-described configuration of the tension sensor 4 is merely one example, and the measurement of tension may be realized using another detection principle.
Information indicating the physical amount acquired by the tension sensor 4 (the strain amount in this embodiment) is input as an electrical signal to the control circuit 20 shown in FIG. 2 .
the control circuit 20 controls the tension adjusting apparatus 5 based on this information.
the control circuit 20 references a look up table that is stored in a memory of the control circuit 20, for example.
the look up table indicates a correlation relationship between the physical amounts and tensions of the knitting yarn 9, for example.
the control circuit 20 compares the obtained tension of the knitting yarn 9 with a set tension that is stored in the memory, and causes the tension adjusting apparatus 5 to operate such that the tension of the knitting yarn 9 approaches the set tension.
the tension adjusting apparatus 5 is caused to operate such that the tension of the knitting yarn 9 increases. Conversely, if the obtained tension is higher than the set tension, the tension adjusting apparatus 5 is caused to operate such that the tension of the knitting yarn 9 decreases.
the tension of the knitting yarn 9 is brought closer to the set tension by repeating this operation of the tension adjusting apparatus 5, measurement by the tension sensor 4, and tension comparison by the control circuit 20.
the tension adjusting apparatus 5 of this embodiment adjusts the tension of the knitting yarn 9 by acting on a portion of the knitting yarn 9 that spans between the introduction guide 21 and the tension sensor 4.
the tension adjusting apparatus 5 is a knitting condition adjustment apparatus that optimizes the tension of the knitting yarn 9 by directly acting on the knitting yarn 9 so as to adjust the tension itself of the knitting yarn 9, which is a knitting condition.
the tension adjusting apparatus 5 is not necessarily required to be provided on the YF 2A, and may be provided at a position of the side tension device of the flat knitting machine 1 shown in FIG. 1 as in conventional technology.
the tension adjusting apparatus 5 of this embodiment is provided at a position on a lateral side of the suspended portion 2b in a front view of the YF 2A from a direction orthogonal to the rail 1R. For this reason, the tension adjusting apparatus 5 does not interfere with a member (e.g., a YF on another rail) in the vicinity of the traveling route of the YF 2A.
the tension adjusting apparatus 5 of this embodiment is configured so as to not protrude beyond the width of the carrier portion 2a in the extending direction of the rail 1R, and thus allowing the YFs 2A and 2B shown in FIG. 1 to be arranged close together in the left-right direction.
the tension adjusting apparatus 5 is provided external to the YF 2A, it is necessary to be capable of transmitting the information acquired by the tension sensor 4 from the YF 2A.
the tension adjusting apparatus 5 of this embodiment adjusts the tension of the knitting yarn 9 by sandwiching the knitting yarn 9 between an immovable fixed piece 51 that is fixed to the lower mounting portion 2L and a movable piece 50 that moves linearly in a direction of movement toward and away from the fixed piece 51.
the movable piece 50 can be configured to be operated by a solenoid or the like, and the force by which the knitting yarn 9 is sandwiched by the fixed piece 51 and the movable piece 50 can be changed by changing the amount of electrical power supplied to the solenoid. The stronger the force sandwiching the knitting yarn 9 is, the more difficult it is for the knitting yarn 9 to move, and the higher the tension of the knitting yarn 9 becomes on a downstream side of the tension adjusting apparatus 5.
the above-described linear movement direction of the movable piece 50 that is to say the direction in which the tension adjusting apparatus 5 acts on the knitting yarn 9, is a direction that is orthogonal to the thickness direction of the YF 2A, that is to say a direction parallel to the planar direction of the main body portion 2M of the YF 2A.
the YF 2A is configured to be able to exchange information with the computer 10 of the flat knitting machine 1 shown in FIG. 1 .
the YF 2A is provided with a transceiver that is optical wireless or the like such that information can be exchanged between the control circuit 20 of the YF 2A and the computer 10.
the transceiver can be provided in the control circuit 20, and can be controlled by a communication control portion provided in the control circuit 20.
the control circuit 20 is capable of selecting information that is to be transmitted, and selecting received information.
the tension adjusting apparatus 5 can change the tension of the knitting yarn 9.
the tension adjusting apparatus 5 may have a configuration in which a pair of comb-shaped members are arranged such that the comb teeth thereof fit between each other.
the tension of the knitting yarn 9 can be changed by arranging the knitting yarn 9 so as to be woven between adjacent comb teeth, and changing the gap between the two comb-shaped members in the thickness direction of the comb-shaped members.
the knitting condition adjustment apparatus of the present invention is not limited to the tension adjusting apparatus 5. Any apparatus can be set as the knitting condition adjustment apparatus of the present invention as long as it can optimize the tension of the knitting yarn 9 as a result of changing some sort of condition related to knitting.
the flat knitting machine 1 may be configured to include a feeding apparatus in which the knitting yarn 9 is sandwiched between a pair of rollers, at least one of which is driven to rotate, and in which the knitting yarn 9 is dynamically fed by rotation of the rollers, and in this case, the feeding apparatus and a feeding control portion for control thereof are respectively set as the knitting condition adjustment apparatus and the knitting condition control unit.
the tension of the knitting yarn 9 can be optimized by adjusting the feeding amount of the knitting yarn 9 based on tension-related information from the tension sensor 4.
the feeding apparatus it is possible to reduce the tension of the knitting yarn 9 by increasing the rotation speed of the rollers so as to increase the feeding amount of the knitting yarn 9.
a cam system which adjusts the amount of the knitting yarn 9 that is pulled by a knitting needle, and a cam control portion for control of the cam system can be respectively set as the knitting condition adjustment apparatus and the knitting condition control unit.
the tension of the knitting yarn 9 can be optimized by adjusting the pulling amount of the knitting needle based on tension-related information from the tension sensor 4.
the concept of adjusting a knitting condition also includes prompting a user to change a knitting condition in order to optimize the tension of the knitting yarn 9.
a tension abnormality notification apparatus which is a display, a warning lamp, or the like for notifying the user of a tension abnormality
a notification control portion for control of the tension abnormality notification apparatus can be respectively set as the knitting condition adjustment apparatus and the knitting condition control unit.
an overall control portion of the flat knitting machine 1 can determine that knitting operations are to be paused.
