Since the greatly projecting configuration is arranged over the entire width direction of the set-up device, the conventional set-up device requires a large mounting space.

  The present invention has been made in view of the above circumstances, and one of its purposes is to provide a set-up device that can reduce the mounting space in a flat knitting machine.

  The set-up device according to the present invention is disposed below the tooth opening between the front needle bed and the rear needle bed in the flat knitting machine, and captures the set-up portion of the knitted fabric to lower the knitted fabric downward. And a plurality of set-up needles, a base portion, a needle control mechanism, and an urging body. The set-up needle is formed by combining a first needle member having a hook housing portion and a second needle member having a hook so as to be relatively slidable. The base portion is arranged so that the plurality of set-up needles can slide. The needle control mechanism slides the first needle member and the second needle member relatively to change the state of the set-up needle between the holding state for holding the set-up portion and the set-up portion. Switch between non-holding state. The urging body urges the first needle member or the second needle member below the tooth opening. The needle control mechanism provided in the set-up device according to the present invention includes a needle side engaging portion provided on a needle member of the first needle member and the second needle member to which the biasing body is not attached. And an action piece having a base side engagement portion that is slidably attached to the base portion and acts on the needle side engagement portion, and moves the action piece up and down along the extending direction of the set-up needle And an elevating mechanism. The needle control mechanism moves the needle side engaging portion up and down by the base side engaging portion, thereby changing the relative positions of the first needle member and the second needle member.

  As one form of the set-up device of the present invention, the urging body is attached to the second needle member, and the needle side engaging portion is constituted by a bat provided on the first needle member. Can be mentioned.

  As one form of the set-up device of the present invention, there is a form in which the needle side engaging part is constituted by a bat, and the base side engaging part is constituted by an accommodation recess for accommodating the butt therein. it can. In this case, the upper end edge of the storage recess pulls the bat downward, or the lower end edge of the storage recess pushes the bat upward, so that the first needle member and the second needle member are relatively Position changes.

  As one form of the set-up device of the present invention, the first needle member and the second needle member may include a pair of slide engaging portions that define a sliding range of both. In that case, one of the slide engaging portions can be slid in the extending direction of the set-up needle, and the other can be slid in the extending direction of the set-up needle. It is set as the structure which is an engagement recessed part accommodated.

As one form of the set-up device of the present invention, the elevating mechanism portion includes a cam follower provided on the action piece, a cam plate disposed on the base portion and having a cam groove engaged with the cam follower , and the base And a drive unit that moves the cam plate in the width direction of the unit. In this embodiment, the cam groove includes an upper end flat portion and a lower end flat portion extending in the width direction of the base portion at the upper end position and the lower end position, respectively. And the said lower end flat part is formed so that the said bat may be pulled down below by the said action piece, and the said set-up needle will be in the said non-holding state by arrange | positioning the said cam follower in the said lower end flat part. . Further, the cam follower is arranged in the upper end flat portion, so that the upper end flat portion is formed so that the bat is pushed upward by the action piece and the set-up needle is in the holding state. .

  As an embodiment of the set-up device of the present invention including the cam follower and the cam plate, the cam groove includes an intermediate flat portion extending in the width direction of the base portion at a position near the lower end flat portion. be able to. In that case, when the cam follower is disposed in the intermediate flat portion, the intermediate flat portion is formed so as to stop at a position immediately before the working piece contacts the bat or a position where the working piece contacts the bat. Yes. Here, since the intermediate flat portion is positioned above the lower end flat portion, the bat is not pulled down even if the action piece is in contact with the bat.

  In the set-up device of the present invention, instead of the needle control mechanism using the swing lever that swings in the thickness direction of the set-up device, the needle control mechanism using the action piece that moves up and down on the base portion of the set-up device Is adopted. Therefore, the set-up device of the present invention is more compact than the conventional set-up device.

  By attaching the urging body to the second needle member having the hook, an appropriate tension can be applied to the set-up portion that is locked to the hook. Moreover, the strength of the first needle member can be made higher by configuring the needle side engaging portion provided on the first needle member with a bat than when the needle side engaging portion is configured with a dent.

  The set-up needle is an elongated and thin member. Therefore, when the needle-side engaging portion is configured with a butt and the base-side engaging portion is configured with a storage recess, the opposite is true (needle-side engagement portion = storage recess, base-side engagement portion = butt). As a result, the strength of the set-up needle can be increased. In addition, by adopting a configuration in which the bat is moved by the upper end edge and the lower end edge of the storage recess, switching between the holding state and the non-holding state can be performed reliably.

  The engaging recess and the engaging recess that define the relative sliding range of the first needle member and the second needle member are provided in the set-up needle, so that the engaging recess when the both needle members are relatively slid. Since the engaging convex part is abutted against the inner wall, the sliding range can be precisely defined. Moreover, it becomes difficult for the second needle member to come off from the first needle member by the slide engagement portion.

  According to the configuration in which the action piece is moved by the engagement between the cam follower and the cam groove, the action piece can be smoothly moved up and down. Further, by forming flat portions at the upper and lower ends of the cam groove, the upper end position and the lower end position of the movement range of the action piece can be determined with high accuracy. As a result, switching from the holding state to the non-holding state and switching from the non-holding state to the holding state can be reliably performed.

  By forming the intermediate flat portion in the cam groove, when the cam follower is moved from the upper end flat portion to the intermediate flat portion, the set-up needle is maintained in the holding state, and the biasing force of the biasing body is applied to the set-up needle. It can be in a non-operational state. By setting the set-up needle in this state, the knitted fabric can be knitted with the flat knitting machine while maintaining a state in which a substantially constant tension is applied to the set-up portion.

As shown in FIG. 3, the set-up needle 2 includes a first needle member 20 and a second needle member 21 that are combined so as to be relatively slidable. The set-up needle 2 is slidably disposed in a needle groove 1g (see FIG. 4) of the base portion 1. The set-up needle 2 disposed in the needle groove 1g is pressed by a band 1b (see FIG. 2) so as not to be detached from the needle groove 1g. The set-up needle 2 is not limited to the configuration arranged in the needle groove 1g, and may be arranged slidably on the needle bed 10 with a cover, a wire, or the like.

[First needle member]
As shown in FIG. 3A, the first needle member 20 includes a slide groove 2g into which the second needle member 21 can be fitted from the right side of the drawing. The set-up needle 2 shown in FIGS. 3B and 3C is formed by fitting the second needle member 21 into the slide groove 2g. At the upper end portion of the first needle member 20, a hook housing portion 2c for housing a hook 2f of the second needle member 21 described later is provided. The hook storage portion 2c is formed in a substantially trapezoidal shape, and the hook storage portion 2c has no portion where the set-up portion of the knitted fabric is caught.

  A slide engagement portion 2 a that defines a relative slide range between the first needle member 20 and the second needle member 21 is provided at an intermediate portion of the first needle member 20. The slide engagement portion 2a of this example is formed by providing a rectangular hole that penetrates the first needle member 20 in the front and back direction of the drawing. The rectangular hole is formed so that a part thereof reaches a position deeper than the slide groove 2g (a position on the left side of the paper surface), and as a result, the slide groove 2g becomes deep at the position of the rectangular hole. The deepened portion (engagement recess) of the slide groove 2g forms the slide engagement portion 2a in this example. In addition, the formation position of this slide engagement part 2a and the slide engagement part 2b mentioned later is not specifically limited, You may exist in any position in the extending | stretching direction of the set-up needle 2.

  At the lower end of the first needle member 20, a bat (needle side engaging portion) 30 is provided that protrudes in the direction toward the base portion 1 (see FIG. 5). The bat 30 constitutes a part of a needle control mechanism 3 (see FIGS. 2, 4 and 5) which will be described later. Here, the formation position of the bat 30 is not particularly limited, and may be any position in the extending direction of the first needle member 20.

[Second needle member]
As shown in FIG. 3A, a hook 2f for hooking a set-up portion of the knitted fabric is provided at the upper end portion of the second needle member 21. The configuration of the hook 2f can be the same as that of Patent Document 1. As shown in FIG. 3B, when the hook 2f is housed in the hook housing portion 2c of the first needle member 20, the hook housing portion 2c has no portion where the set-up portion of the knitted fabric is caught. 2 becomes a non-holding state in which the set-up portion of the knitted fabric cannot be locked. On the other hand, when the hook 2f is exposed from the hook housing portion 2c as shown in FIG. 3C, the set-up portion of the knitted fabric can be hooked on the hook 2f. Can be locked.

A slide engagement portion 2 b that regulates the slide range of the second needle member 21 is provided at an intermediate portion of the second needle member 21 together with a slide engagement portion (engagement recess) 2 a of the first needle member 20. . The slide engagement portion 2b of the present example protrudes toward the slide groove 2g of the first needle member 20 (a direction orthogonal to the extending direction of the set-up needle 2) and is housed inside the engagement recess 2a of the first needle member 20. It is a protrusion (engagement convex part). As already described, the slide engagement portion 2a of the first needle member 20 is an engagement recess in which the slide groove 2g is partially deepened. The vertical direction of the engagement recess 2a (the extending direction of the set-up needle 2) ) Is larger than the vertical width of the engaging projection 2b. Therefore, when the first needle member 20 is slid upward as shown in FIG. 3 (C), the engaging convex portion 2b is abutted against the lower end edge of the engaging concave portion 2a, and as shown in FIG. 3 (B). the first needle member 20 when slid downward, the engaging projection 2b is stopped against the upper edge of the engaging recess 2 a to. As described above, according to the configuration in which the slide of the first needle member 20 is regulated by the stopper, the relative slide range of the first needle member 20 and the second needle member 21 is precisely defined. By the engagement of the slide engagement portions 2a and 2b, there is also an effect that the second needle member 21 can be prevented from being detached from the first needle member 20 in the slide direction (the same as the extending direction of the set-up needle 2). It is also possible to form an engaging convex portion in the slide groove 2g of the first needle member 20 and to form an engaging concave portion that engages with the engaging convex portion in the second needle member 21.

  At the lower end portion of the second needle member 21, a locking portion 2j that locks one end of the coil spring 4 (see FIG. 4) is provided. As shown in FIG. 4, the other end of the coil spring 4 is locked to a hook-shaped locking member 1 j attached to the installation portion 11 of the base portion 1. That is, the second needle member 21 and the first needle member 20 combined with the second needle member 21 are in a state of being biased downward by the coil spring 4 that is a tension spring. Unless the first needle member 20 is moved, the set-up needle 2 in the holding state is maintained in the holding state, and the set-up needle 2 in the non-holding state is maintained in the non-holding state.

  In addition to the configuration described above, the first needle member 20 (second needle member 21) has a set-up needle in the needle groove 1g as a configuration that defines the slide range of the entire set-up needle 2 in the needle groove 1g. A lower end defining portion 2w (2x) that determines the lower end of the slide range 2 and an upper end defining portion 2y (2z) that determines the upper end of the slide range are provided. The lower end defining portion 2w (2x) is abutted against the contact portion 1t of the base portion 1 in FIG. 5 when the set up needle 2 slides downward, and defines the lower end of the slide range of the entire set up needle 2. . On the other hand, the upper end defining portion 2y (2z) is abutted against the band 1b attached to the base portion 1 in FIGS. 4 and 5 when the set-up needle 2 slides upward, so that the entire slide range of the set-up needle 2 is reached. Define the top edge of

  Here, the set-up needle only needs to have a configuration in which the set-up needle is in a holding state and a non-holding state by relatively sliding the first needle member and the second needle member, and is limited to the above-described configuration. It is not done. For example, a set-up needle as described in FIGS. 1 to 3 of Japanese Patent Laid-Open No. 5-71051 and Japanese Patent Publication No. 2011-513601 may be used. The former set-up needle is a set-up needle that is held when a member corresponding to the second needle member 21 having the hook 2f slides downward. Contrary to the set-up needle 2 of this example shown in FIG. 3, the latter set-up needle is knitted in a holding state when a member corresponding to the first needle member 20 having the hook housing portion 2c slides downward. It is a needle. Further, the biasing body that applies the biasing force to the second needle member 21 is not limited to the coil spring 4. For example, the urging body may be made of an elastic material such as rubber.

≪Needle control mechanism≫
As shown in FIGS. 4 and 5, the needle control mechanism 3 of the present example includes a bat 30 provided at the lower end portion of the first needle member 20 and an action piece 31 slidably attached to the installation portion 11 of the base portion 1. And an elevating mechanism 32 (see FIG. 2) for moving the action piece 31 up and down.

[Action piece]
The action piece 31 includes a plate-like portion 31A having a rectangular storage recess (needle side engagement portion) 31w and an operating arm 31B connected to the lower portion of the plate-like portion 31A as shown in FIG. FIG. 4 shows only a part of the plate-like portion 31A). As shown in FIG. 2, the action piece 31 of this example is a member in which two operating arms 31 </ b> B are connected to a plate-like portion 31 </ b> A having substantially the same width as the width direction of the base portion 1. As shown in FIG. 4, the operating arm 31 </ b> B is fitted in the slide recess 1 s of the base portion 1, so that the action piece 31 moves on the base portion 1 along the extending direction (vertical direction on the paper surface) of the set-up needle 2. Slide. The action piece 31 is provided on the back side of the coil spring 4 on the surface side of the installation portion 11. The operating arm 31 </ b> B of the action piece 31 is covered with a cover member 13 (see FIG. 2) so that the action piece 31 does not come off the base portion 1. The cover member 13 is disposed on the back side of the coil spring 4 and is fixed to the installation portion 11. Here, the number of the operating arms 31B connected to the plate-like portion 31A is not particularly limited.

  The bat 30 of the first needle member 20 is disposed in the storage recess 31 w provided in the plate-like portion 31 </ b> A of the action piece 31. The number of bats 30 arranged in one storage recess 31w, that is, the number of set-up needles 2 corresponding to one storage recess 31w is not particularly limited. Further, the number of storage recesses 31w provided in the action piece 31 is not particularly limited. The storage recess 31w may be a recess having a bottom portion or a through-hole penetrating the plate-like portion 31A (the latter in this example). That is, in the configuration of this example, the set-up needle 2 can be moved in the range of the length of the storage recess 31 w in the extending direction of the set-up needle 2. When knitting a knitted fabric having a different number of knitting courses of wale for each constant knitting width, the set-up needle 2 is arranged along the shape of the knitted fabric. For example, in the example shown in FIG. 4A, the two set-up needles 2 in the center corresponding to the shape of the knitted fabric are located above the other set-up needles 2 within the length of the storage recess 31w. Has moved to. In that case, the urging force of the coil spring 4 in the downward direction of the paper acts on the two center setting needles 2 more strongly than the other setting needles 2. As a result, a pulling force corresponding to the number of knitting courses of each wale for each constant knitting width of the knitted fabric can be applied to the knitted fabric.

  Further, according to the configuration in which the bat 30 of the first needle member 20 is disposed in the storage recess 31w, the bat 30 is pushed upward by the lower edge of the storage recess 31w by moving the plate-like portion 31A upward. The bat 30 can be pulled downward by the upper edge of the storage recess 31w by moving the plate-like portion 31A downward. The raising and lowering of the bat 30 is related to switching between the holding state and the non-holding state of the set-up needle 2 as described later with reference to FIG.

  A cam follower 31 </ b> C is provided on the lower end side of the operating arm 31 </ b> B of the action piece 31. The cam follower 31C is a cylindrical member that protrudes from the surface of the operating arm 31B, and is configured to be rotatable by a bearing. The cam follower 31C may be a cylindrical member that does not rotate, or a member in which a sphere is provided at the tip of the shaft portion. In that case, damage to the cam follower 31C and the cam groove 32g can be suppressed by configuring the portion of the cam follower 31C that is in sliding contact with the cam groove 32g with a material that is easy to slide.

[Elevating mechanism]
The elevating mechanism 32 includes the cam follower 31C, a cam plate 32A having a cam groove 32g with which the cam follower 31C is engaged, and a drive unit 32B (see FIG. 2) for moving the cam plate 32A. The number of cam grooves 32g corresponds to the number of cam followers 31C.

Cam plate 32A on the lower end side of the position of the installation portion 11 is provided to be slidable in the width direction of the base portion 1 (a direction orthogonal to the extending direction of the knitted out needle 2). The surface of the cam plate 32 </ b> A is covered with the cover member 14 (see FIG. 2) so as not to be detached from the installation portion 11. The cam groove 32g provided on the cam plate 32A extends as a whole in an oblique direction (a direction intersecting the width direction of the base portion 1). The cam groove 32g includes an upper end flat portion 320 and a lower end flat portion 329 extending in the width direction of the base portion 1 at the upper end position and the lower end position, respectively. By arranging the cam follower 31C on the lower end flat part 329, the lower end flat part 329 is formed so that the bat 30 is pulled downward by the action piece 31 and the set-up needle 2 is not held. Further, the cam follower 31C is arranged on the upper end flat portion 320, whereby the upper end flat portion 320 is formed so that the bat 30 is pushed upward by the action piece 31 and the set-up needle 2 is held. According to the configuration in which the action piece 31 is moved by the engagement between the cam follower 31C and the cam groove 32g, the action piece 31 can be smoothly moved up and down. Further, by forming the flat portions 320 and 329 at the upper and lower ends of the cam groove 32g, the upper end position and the lower end position of the movement range of the action piece 31 can be determined with high accuracy.

  Here, instead of the set-up needle 2 shown in FIG. 3, a set-up needle (see Japanese Patent Application Publication No. 2011-513601) that is held when the first needle member having the hook housing portion slides downward is used. In this case, when the cam follower 31C is arranged on the upper flat portion 320 (lower flat portion 329), the set-up needle is in a non-holding state (holding state).

  The cam groove 32g further includes an intermediate flat portion 325 extending in the width direction of the base portion 1 at a position near the lower end flat portion 329. The intermediate flat portion 325 is formed so that when the cam follower 31 </ b> C is disposed in the intermediate flat portion 325, the action piece 31 stops at a position immediately before acting on the bat 30. Here, unlike the cam groove 32g of this example, the cam groove 32g without the flat portions 320, 329, and 325 may be used.

  As shown in FIG. 2, the drive unit 32B that slides the cam plate 32A includes a rack 32r formed at the lower end of the cam plate 32A, a pinion 32p that engages with the rack 32r, a motor 32m that rotates the pinion 32p, Consists of. That is, in this example, it is configured so that the state of all the set-up needles 2 provided in the set-up device 100 can be switched by one motor 32m.

  Here, the raising / lowering mechanism part 32 which moves the action piece 31 up and down should just be a structure which does not protrude largely in the thickness direction of the set-up apparatus 100, and is not necessarily limited to the structure of embodiment. For example, a rack extending in the vertical direction may be provided on the action piece 31 and the action piece 31 may be moved up and down by a pinion, or the action piece 31 may be moved up and down using a crank mechanism. In addition, the raising / lowering mechanism part 32 can also be comprised with the structure which moves the action piece 31 directly up and down, for example, an actuator using a solenoid, an air cylinder, etc., for example.

≪Operation of set-up needle by needle control mechanism≫
With reference to FIG. 5, how the set-up needle 2 operates by the needle control mechanism 3 will be described. FIG. 5A shows a state in which the cam follower 31C is pulled down to the lower limit position (the position of the lower flat portion 329 in FIG. 4) by the cam groove 32g (see FIG. 4) of the cam plate 32A. The upper end edge of the storage recess 31w of the action piece 31 lowers the bat 30 of the first needle member 20 slightly before the cam follower 31C is lowered to the lower limit position (see the central circled portion). When the bat 30 is pulled downward, the first needle member 20 slides downward, and the hook 2f is stored in the hook storage portion 2c as shown in the upper circled portion. That is, in FIG. 5A, the set-up needle 2 is in a non-holding state.

  FIG. 5C shows a state where the cam follower 31C is pushed up to the upper limit position (the position of the upper end flat portion 320 in FIG. 4) by the cam groove 32g (see FIG. 4) of the cam plate 32A. The lower end edge of the storage recess 31w of the action piece 31 pushes up the bat 30 of the first needle member 20 just before the cam follower 31C is pushed up to the upper limit position (see the central circled portion). When the bat 30 is pushed upward, the first needle member 20 slides upward, and the hook 2f is exposed from the hook storage portion 2c as shown in the upper circled portion. That is, in FIG. 5C, the set-up needle 2 is in the holding state.

  When the set-up portion is captured by the set-up needle 2, the set-up needle 2 is set to a non-holding state (see FIG. 5A), the base portion 1 of the set-up device 100 is raised toward the tooth gap GP, and the knitting is performed. The set-up needle 2 is disposed at the position of the protruding portion. Next, the set-up needle 2 is held (see FIG. 5C), the base portion 1 is lowered, and the set-up portion is captured by the hook 2f of the set-up needle 2. Then, the base portion 1 is lowered, and the knitted fabric is knitted while applying tension to the set-up portion. When the set-up portion passes the lowering rollers 301 and 302 (FIG. 1), the knitted fabric portion is sandwiched by the lowering rollers 301 and 302, and the cam plate 32A shown in FIG. Is in a non-holding state (see FIG. 5A).

  Here, the cam plate 32A in FIG. 4 is moved to the left to capture the set-up portion with the set-up needle 2 held (see FIG. 5C), and then the cam plate 32A in FIG. 4 is moved to the right. The cam follower 31C may be disposed at the position of the intermediate flat portion 325 by moving the cam follower 31C. By doing so, the upper end edge of the storage recess 31 w of the action piece 31 stops at a position immediately before contacting the bat 30, as shown in the central circled portion of FIG. As a result, as shown in the enlarged view of the upper circle, the set-up needle 2 is maintained in the holding state, and the upward movement of the bat 30 is restricted by the upper edge of the storage recess 31w. By limiting the movement of the bat 30, the knitted fabric can be knitted in a state where the urging force of the coil spring 4 is not applied to the set-up needle 2. Note that when the cam follower 31C is disposed in the intermediate flat portion 325, the upper end edge of the storage recess 31w may contact the bat 30. However, it is necessary to form the intermediate flat portion 325 so that the set-up needle 2 is maintained in the holding state.

≪Effect≫
As shown in FIG. 5, the set-up device 100 of the present example largely protrudes in the thickness direction of the set-up device 100 (same as the thickness direction of the base portion 1) except for the drive unit 32B (see FIGS. 1 and 2). Therefore, it is more compact than the set-up device of Patent Document 1. Therefore, the mounting space of the set-up device 100 in the flat knitting machine is smaller than that of the conventional set-up device.

  Moreover, as shown in FIG. 1, according to the set-up device 100 of the present example, it is possible to make it easy to be provided with the lowering device 300 in the flat knitting machine. When the set-up device 100 captures the set-up portion of the knitted fabric, the base portion 1 of the set-up device 100 is moved toward the tooth gap GP. At that time, the base portion 1 passes between the lowering rollers 301 and 302 of the lowering device 300. Here, in the base portion 1 of the set-up device 100 of the present example, the portion that passes through the lowering rollers 301 and 302 does not have a configuration that protrudes greatly in the thickness direction of the base portion 1. Problems such as contact with the lowering rollers 301 and 302 do not occur. Therefore, the setting-up device 100 and the lowering device 300 are provided side by side without any special design change such as providing a mechanism for expanding the distance between the lowering rollers 301 and 302 to a position where the setting-up device 100 can be avoided. be able to. In addition, although the drive part 32B protrudes largely in the thickness direction of the base part 1, since it exists in the position which does not contact the lowering apparatus 300, it does not cause the said malfunction.

<Embodiment 2>
Unlike the first embodiment, the coil spring 4 may be attached to the lower end of the first needle member 20, and the butt (needle side engagement portion) 30 may be provided on the second needle member 21 having the hook 2f. In other words, the second needle member 21 having the hook 2f may be slid with respect to the first needle member 20 to switch between the non-holding state and the holding state of the set-up needle 2. In this case, the set-up needle 2 is in the holding state when the cam follower 31C of FIG. In order to apply the urging force of the coil spring 4 to the set-up portion of the knitted fabric via the set-up needle 2, after the set-up portion is captured by the set-up needle 2, the cam follower 31C is moved from the lower end flat portion 329 to the upper end flat portion. What is necessary is just to move to the front of 320.

<Embodiment 3>
Unlike Embodiments 1 and 2, the base-side engagement portion provided on the action piece 31 can be a butt, and the needle-side engagement portion provided on the set-up needle 2 can be a storage recess. The storage recess formed in the set-up needle 2 can be formed by cutting out a part of the set-up needle 2. In addition, two protrusions spaced apart in the extending direction of the set-up needle 2 can be formed on the set-up needle 2, and a portion sandwiched between the two protrusions can be used as a storage recess. The storage recess may be provided in either the first needle member 20 or the second needle member 21.
