Japanese Unexamined Patent Publication No. 6-14889

  Here, it is desired to develop a flat knitting machine having a fixing structure that can improve the fixing workability of the needle plate and can be fixed more firmly.

  The conventional fixing structure using caulking takes time for caulking. Further, not only when assembling, but also when the needle plate is replaced due to wear or damage, caulking is necessary, and a reduction in work load is desired.

  Even if there is no problem in normal use, if the knitting speed (carriage traveling speed) increases, the lateral load applied to the needle plate (in the direction perpendicular to the advancing / retreating direction of the knitting needle) increases and the caulking becomes loose. There is a fear.

  Therefore, an object of the present invention is to provide a flat knitting machine that can firmly fix a needle plate to a needle bed and is excellent in this fixing workability.

  The flat knitting machine of the present invention includes a needle plate provided upright in each of a plurality of plate grooves formed in parallel to the needle bed, and a knitting needle disposed between adjacent needle plates. The flat knitting machine is provided on the opposite side of the needle bed in the needle bed, and is disposed along the plate fixing groove and a plate fixing groove that opens above the needle bed and extends in a direction intersecting the plate groove. A plate fixing member, a tightening member that fixes the plate fixing member to the needle bed, and a fixing recess that opens below the needle plate and engages the plate fixing member. The plate fixing member has an inclined surface that applies a pressing force to the fixing recess when the tightening member is tightened and attracts the needle plate below the needle bed.

  The plate fixing member can be composed of a belt-like attracting member having an inclined surface that directly contacts the fixing recess. Alternatively, the plate fixing member includes a belt-like attracting member having an inclined surface, and a linear action member that abuts the inclined surface and the fixing recess and applies a pressing force of the attracting member to the fixing recess. preferable.

  The flat knitting machine according to the present invention is further provided in an intermediate portion of the needle bed in the direction in which the plate groove is formed. The intermediate knitting machine opens above the needle bed and extends in a direction intersecting the plate groove, and an intermediate support groove. It is preferable to include a linear support member disposed along the needle plate and an intermediate support recess that opens below the needle plate and supports the needle plate by contacting the support member when the needle plate is disposed in the plate groove. .

  The flat knitting machine of the present invention is further provided on the side of the mouth of the needle bed, and opens above the needle bed and extends in a direction intersecting the plate groove, and the height defining groove. A linear height defining member to be arranged, and a height that opens below the needle plate and positions the needle plate in the height direction by contacting the height defining member when the needle plate is disposed in the plate groove. A configuration including a prescribed recess is preferable.

  According to the configuration of the present invention, since the needle plate can be fixed to the needle bed via the plate fixing member by tightening with the tightening member, the caulking operation and the application of the adhesive are unnecessary, and the number of parts is small. The burden of fixing work can be reduced. And according to the structure of this invention, since it is a fixing structure by the mechanical engagement using the pressing force by a plate fixing member, a needle plate is made into a needle bed rather than the conventional method using caulking and an adhesive agent. Can be firmly fixed. Therefore, in the flat knitting machine of the present invention, even if the knitting speed is increased, the fixed state is hardly loosened due to an increase in the load applied to the needle plate.

  Further, if the inclined surface of the plate fixing member is in direct contact with the fixing recess, the number of parts is the smallest, and the arrangement time of the members constituting the fixing structure can be shortened.

  On the other hand, when the plate fixing member includes the attracting member and the action member, it is easy to release the fixed state of the needle plate, and the replacement workability is excellent. In this configuration, by loosening the tightening member and pulling out the working member, a gap is created between the pulling member and the fixed recess, so that the needle plate can be easily removed without completely removing all the tightening members. Pull upward from the groove.

  Further, when the intermediate portion of the needle plate is supported, it is possible to suppress the needle plate from floating from the plate groove when the knitting speed is increased. When the knitting speed is fast, the portion of the needle plate that protrudes from the plate groove moves so as to wave in the vertical direction, and it tends to float up from the plate groove, but by supporting the intermediate portion of the needle plate, such a state can be achieved. It can be suppressed.

  Furthermore, if the needle plate is positioned in the height direction in the vicinity of the tooth mouth, the height of the needle plate on the tooth mouth side can be accurately aligned at a desired position. Therefore, in this flat knitting machine, it is easy to place a member for fixing the relative positions of the needle plates arranged in parallel, and the vertical movement of the knitting needles can be suppressed during the knitting operation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, the overall configuration of the flat knitting machine of the present invention will be described with reference to a conventional flat knitting machine (FIG. 5).

Embodiment 1
<Needle bed and needle plate>
FIG. 1 is a schematic view of a needle bed 1 and a needle plate 2 used in the flat knitting machine of the present invention. Similar to the needle bed of a conventional flat knitting machine, the needle bed 1 includes a plurality of plate grooves 10 formed in parallel with the longitudinal direction of the needle bed 1 (perpendicular to the paper surface), and a direction orthogonal to the plate grooves 10. It has a front end locking groove 11 in which the wire 31 is formed, and the difference from the conventional needle bed is that it is on the opposite side (rear end side) to the mouth g, in the direction orthogonal to the plate groove 10 (paper surface). The plate fixing groove 12 extends in the vertical direction.

  The plate fixing groove 12 is a uniform trapezoidal groove extending from one side end side (front side of the paper surface) to the other side end side (back side of the paper surface) of the needle bed 1 and above the needle bed 1 ( It opens to the top of the page. The bottom surface 12c constituting the plate fixing groove 12 is substantially flush with the rear end side of the bottom surface 10a of the plate groove 10, and the tooth surface 12a is an inclined surface that intersects the bottom surface 12c non-orthogonally (obtuse angle). The rear end side surface 12b is a vertical surface orthogonal to the bottom surface 12c. The tooth opening side surface 12a is inclined so as to descend from the tooth opening g side toward the rear end side.

  A plate fixing member 6 is disposed along the plate fixing groove 12. The plate fixing member 6 includes a belt-like attracting member 60 having a trapezoidal shape whose end faces are line symmetrical, and a wire 61 (linear action member). The attracting member 60 is inclined such that one side surface 60a is in contact with the tooth side surface 12a of the plate fixing groove 12, and the other side surface (inclined surface) 60b is opposite to the tooth side surface 12a with the same inclination, that is, Inclined so as to descend from the rear end side toward the tooth opening g side. The pulling member 60 is provided with a bolt hole 60c through which a bolt 7 (clamping member) is inserted at a central portion thereof, and is fixed to the needle bed 1 by the bolt 7. The needle bed 1 is also provided with a needle bed bolt hole 15 into which the bolt 7 is screwed. A plurality of needle bed bolt holes 15 penetrate from the lower surface 1D of the needle bed 1 to the bottom surface 12c of the plate fixing groove 12 and are provided at equal intervals in the longitudinal direction of the needle bed 1. The position of the wire 61 in the plate fixing groove 12 is that the depth of the plate fixing groove 12 is slightly shallower (the bottom surface of the plate fixing groove 12 is raised), but the entire surface of the plate fixing groove 12 is It may be a single bottom surface. Note that the pulling member 60 and various wires arranged in the flat knitting machine of this embodiment and the embodiments described later are all one continuous long material. Each wire is a member having a circular cross section that extends linearly and has a uniform diameter in the longitudinal direction.

  Further, the needle bed 1 is different from the conventional needle bed in that an intermediate support groove 13 extending in a direction orthogonal to the plate groove 10 is provided at an intermediate portion in the plate groove 10 forming direction (left and right direction in the drawing). The intermediate support groove 13 is opened above the needle bed 1, and is inclined so as to descend from the mouth g side toward the rear end side, similarly to the tooth side surface 12a of the plate fixing groove 12. The needle bed 1 has a uniform polygonal shape from one side end side to the other side end side. A wire 33 (linear support member) that contacts the needle plate 2 and supports the needle plate 2 is inserted into the intermediate support groove 13. As with the intermediate support groove 13, the front end locking groove 11 is also inclined so as to descend from the tooth opening g side toward the rear end side, and so as to descend from the rear end side toward the tooth opening g side. The inclination of the conventional flat knitting machine (see FIG. 5) that is inclined is opposite to that of the leading end locking groove.

  The needle plate 2 used in the flat knitting machine of the present invention is also a needle plate to which the movable sinker exemplified when explaining the conventional flat knitting machine can be attached. The needle plate 2 includes a tip locking recess 21 formed at a position corresponding to the tip locking groove 11 of the needle bed 1, and an engagement groove into which a steel strip or a wire for fixing a plurality of needle plates 2 is fixed. 25 and an engagement hole 26. The needle plate 2 is different from the prior art in that it has a fixing recess 22 formed at a position corresponding to the plate fixing groove 12.

  The fixing recess 22 is a trapezoidal recess, the side surface 22a of the tooth mouth constituting the fixing recess 22 is a vertical surface orthogonal to the longitudinal direction (left and right direction of the paper surface) of the needle plate 2, and the rear end side surface 22b is a pulling side. The inclined surface having an inclination along the inclined surface 60b on the rear end side of the attaching member 60, that is, inclined so as to descend from the rear end side toward the tooth opening g side. The inclination is opposite to that of the intermediate support recess 23.

  The needle plate 2 is also different from the conventional flat knitting machine (see FIG. 5) in that the needle plate 2 includes an intermediate support recess 23 formed at a position corresponding to the intermediate support groove 13. The intermediate support recess 23 has a U-shape inclined so as to descend from the tooth opening g side to the rear end side, that is, to rise from the rear end side to the tooth opening g side, similarly to the intermediate support groove 13. It is a dent. As with the intermediate support recess 23, the front end locking recess 21 is also inclined so as to descend from the tooth opening g side toward the rear end side, and so as to descend from the rear end side toward the tooth opening g side. The inclination of the conventional flat knitting machine (see FIG. 5) which is inclined is opposite to that of the tip locking recess.

<Needle plate fixing procedure>
When the needle plate 2 is fixed to the needle bed 1, first, the wires 31 and 33 are disposed in the distal end locking groove 11 and the intermediate support groove 13, respectively. Both the wires 31 and 33 have a diameter slightly smaller than the width (length in the left-right direction on the paper surface) of the grooves 11 and 13 arranged.

  Next, the tooth g side of the needle plate 2 is fitted into the plate groove 10 of the needle bed 1. At this time, the needle plate 2 is fitted so that a part of the lower surface of the needle plate 2 is in contact with the bottom surface 10a of the plate groove 10. Then, the needle plate 2 is moved to the rear end side, and the front end locking recess 21 and the intermediate support recess 23 are locked to the wires 31 and 33, respectively. At this time, the both concave portions 21 and 23 are inclined so as to descend from the tooth opening g side toward the rear end side, so that the needle plate 2 can be easily pulled toward the rear end side of the needle bed 1. Further, by moving the needle plate 2 toward the rear end side, the fixed concave portion 22 is aligned with the position of the plate fixing groove 12, and the fixed concave portion 22 is engaged with the pulling member 60.

  Next, the attracting member 60 is inserted in a direction perpendicular to the paper surface into a trapezoidal space surrounded by the plate fixing groove 12 and the fixing recess 22. Since the space is sufficiently wider than the cross section of the attracting member 60, the attracting member 60 can be easily inserted. After insertion, the pulling member 60 is moved to the tooth opening g side so that the side surface 60a of the pulling member 60 on the side of the tooth opening g contacts the tooth opening side surface 12a of the plate fixing groove 12, and A wire 61 is inserted in a direction perpendicular to the paper surface into a space surrounded by the inclined surface 60b and the rear end side surface 12b of the plate fixing groove 12 and the rear end side surface 22b of the fixing recess 22. The wire 61 makes point contact with the inclined surface 60b, the bottom surface 12c of the plate fixing groove 12, and the rear end side surface 22b of the fixing recess 22.

  Next, the bolt 7 is screwed into the needle bed bolt hole 15 of the needle bed 1 and the bolt hole 60 c of the pulling member 60 to fix the pulling member 60 to the needle bed 1. When the bolt 7 is tightened, the side surface 60a of the pulling member 60 on the side of the tooth opening g presses the tooth side surface 12a toward the tooth opening g side of the needle bed 1 and downward, and the rear end of the pulling member 60 The side inclined surface 60b presses the wire 61, and this wire 61 further presses the fixing recess 22 (the rear end side surface 22b) of the needle plate 2 so as to attract the needle bed 1 toward the rear end side and downward. . Further, the wire 61 also presses the bottom surface 12c of the plate fixing groove 12 downward. Due to the pressing force that acts as the bolt 7 is tightened, the entire needle plate 2 is pulled to the rear end side of the needle bed 1 through the plate fixing member 6, Locking (wire 31 and tip locking recess 21), locking of the intermediate portion (wire 33 and intermediate support recess 23), and locking of the rear end portion (plate fixing member 6 and fixing recess 12) causes the plate groove It is fixed to needle bed 1 without lifting from 10. Therefore, the needle plate 2 is not displaced in any of the longitudinal direction (left and right direction on the paper surface) and the vertical direction (up and down direction on the paper surface). By this process, a fixed structure in which the needle plate 2 is fixed to the needle bed 1 is constructed.

  In the present embodiment, the needle bed bolt hole 15 is provided so that the head of the bolt 7 does not protrude from the lower surface 1D of the needle bed 1, and the bolt 7 is selected. By using such a bolt 7, the bolt 7 does not get in the way when the needle bed 1 is mounted on the pedestal 100 as shown in FIG. If the base 100 is provided with a notch 101 near the location where the rear end of the needle bed 1 is placed, the bolt 7 can be placed and tightened with the needle bed 1 mounted on the base 100, and fixed workability Excellent.

  Then, as shown in FIG. 5, the needle plates 2 are integrally connected by the wires P1 to P5 penetrating the needle plates 2 and the steel strip PP. Also, the needle plates 2 are connected together so that the position of the needle plate 2 in the height direction on the side of the mouth g is not displaced, and the wires 36 that pass through the engagement holes 26 of the needle plates 2 are engaged. A steel strip 35 that passes through the groove 25 is attached. Finally, the knitting needle 4 is disposed in the needle groove 40 formed between the adjacent needle plates 2 so that the knitting needle 4 does not come off from the needle groove 40.

  As another fixing procedure, the following procedure can be used. First, as described above, the wires 31 and 33 are arranged in the tip locking groove 11 and the intermediate support groove 13, and the pulling member 60 is inserted into the plate fixing groove 12 in the direction perpendicular to the paper surface and temporarily tightened with the bolt 7. Temporarily fix to needle bed 1. Next, the needle plate 2 is fitted into the plate groove 10 as described above, and then the needle plate 2 is moved to the rear end side, and the wires 31, 33 are attached to the front end locking recess 21 and the intermediate support recess 23. In addition to locking, the fixed recess 22 is engaged with the pulling member 60. Then, as described above, the wire 61 is inserted in the space surrounded by the plate fixing groove 12 and the fixing recess 22 in the direction perpendicular to the paper surface, and then the bolt 7 is finally tightened.

<Effect>
The flat knitting machine of this embodiment can firmly fix the needle plate 2 to the needle bed 1 by a simple operation of tightening the bolt 7 without using an adhesive or caulking. Further, since this flat knitting machine mechanically connects the needle plate 2 and the needle bed 1, the fixed state is difficult to loosen even when high-speed knitting is performed. Since this flat knitting machine does not require caulking, the needle bed 1 and the needle plate 2 do not have V-shaped notches.

  Further, since the flat knitting machine of the present embodiment has a configuration in which the plate fixing member 6 includes the pulling member 60 and the wire 61, the fixing recess 22 (rear end side surface 22b), the plate fixing groove 12 (bottom surface 12c), and Since the attracting member 60 (inclined surface 60b) and the wire 61 are in point contact, the tightening is good and the needle plate 2 can be securely fixed to the needle bed 1. Further, even if the bolt 7 that fastens the pulling member 60 is not completely removed, the engagement between the needle plate 2 and the plate fixing member 6 is released by loosening the bolt 7 and pulling the wire 61 in the direction perpendicular to the paper surface. Since the fixed state of the needle plate 2 and the needle bed 1 can be released, the needle plate 2 can be extracted from the plate groove 10. Therefore, this flat knitting machine can easily replace the needle plate 2.

  Furthermore, the flat knitting machine of the present embodiment is configured to include an intermediate support mechanism including an intermediate support groove 13, an intermediate support recess 23, and a wire 33. With this configuration, even when the knitting speed is increased, the intermediate portion of the needle plate 2 can be prevented from being lifted and a strong fixed state can be easily maintained. Therefore, this flat knitting machine can be used for high-speed knitting such as 2.0 m / s or more.

(Modification)
In Embodiment 1 described above, the flat knitting machine including the movable sinker having the sinker plate fixed in the vicinity of the mouth plate side of the needle plate is illustrated. It may be a machine.

Embodiment 2
FIG. 3 is a schematic view of another embodiment of the needle bed 1 and the needle plate 2 used in the flat knitting machine of the present invention, and FIG. 4 is a schematic view showing a virtual arrangement state of the knitting needles and the sinker plate in this embodiment. FIG. The basic configuration of the needle bed 1 is the same as that of the first embodiment, and the difference is that it includes a positioning mechanism capable of positioning the needle plate in the height direction. Hereinafter, the positioning mechanism will be mainly described, and description of other configurations will be omitted.

  The needle bed 1 has a height defining groove 14 extending in a direction orthogonal to the plate groove 10. The height regulating groove 14 is provided in the needle bed 1 on the side of the tooth opening g from the tip locking groove 11 and at a relatively thick portion. The height defining groove 14 is a uniform rectangular groove extending from one side end side to the other side end side of the needle bed 1 and opens above the needle bed 1. Further, the height defining groove 14 is shallower than the plate groove 10 (here, shallower than the front end locking groove 11 and the intermediate support groove 13), similarly to the front end locking groove 11 and the intermediate support groove 13, and Since multiple grooves are not formed in parallel like the plate groove 10, there is little heat and distortion accumulated in the needle bed 1 during processing, and there is a great variation in depth in the formation direction of the height regulating groove 14. Few.

  In the height defining groove 14, a wire 34 (a linear height defining member) is disposed. The wire 34 has a diameter smaller than the width of the height defining groove 14 (length in the left-right direction on the paper surface). The height of the needle plate 2 is determined by the depth of the height defining groove 14 and the diameter of the wire 34.

  The needle plate 2 has a U-shaped height defining recess 24 formed at a position corresponding to the height defining groove 14. The height defining recess 24 may be formed by notching from the position corresponding to the height defining groove 14 to the tip of the needle plate 2, but to the extent that the wire 34 can be disposed in the height defining recess 24. If the size is small, the function can be sufficiently exhibited, and the removal amount of the needle plate 2 can be reduced, so that the strength of the needle plate 2 does not decrease.

  When the needle plate 2 is fitted into the plate groove 10, the wires 31, 33, and 34 are disposed in the tip locking groove 11, the intermediate support groove 13, and the height defining groove 14, respectively. In this state, the needle plate 2 is fitted into the plate groove 10. At this time, since the wire 34 disposed in the height defining groove 14 is disposed higher than the wires 31 and 33, the tip locking recess 21 and the intermediate support recess 23 are in contact with the wires 31 and 33 in the height direction. However, the height defining recess 24 is easily in contact with the wire 34. The height defining recess 24 abuts on the wire 34, whereby the position of the needle plate 2 in the height direction is defined, and the needle plate 2 is supported by the wire 34. That is, the vicinity of the tooth plate g side of the needle plate 2 is disposed in the plate groove 10 in a floating state without contacting the bottom surface 10a of the plate groove 10. The needle plate 2 is moved to the rear end side, and the front end locking recess 21 and the intermediate support recess 23 are locked to the wires 31 and 33.

  The height defining groove 14 has little variation in depth in the formation direction, and the wire 34 has the same diameter with high accuracy, so that the position of the needle plate 2 in the height direction is also precisely aligned with the desired height. . In addition, since the wire 34 and the needle plate 2 are in point contact, the height of each needle plate 2 can be accurately adjusted to a desired height, and this aligned state can be stably maintained.

  The procedure after the needle plate 2 is fitted into the plate groove 10 is the same as that in the first embodiment. In this embodiment, since there is little variation in the position of each needle plate 2 in the height direction, the wire 36 and the steel strip 35 can be easily arranged.

  Further, the flat knitting machine of the present embodiment is configured to suppress the vertical blur of the needle body 41 (see FIG. 5) by the spacer 5 (see FIG. 5) that engages the needle plate 2 near the mouth of the needle plate 2. It is. This flat knitting machine is provided with the above-described positioning mechanism in the height direction on the side of the tooth opening g, so that the height of the needle plate 2 standing on the needle bed 1 becomes a desired height in the vicinity of the tooth opening g. Since they are aligned with high precision, the position in the height direction of the spacer 5 attached to the needle plate 2 is also aligned with the desired height with high precision. Accordingly, when the knitting needle 4 (see FIG. 5) is advanced or retracted in the extending direction of the needle groove 40 (see FIG. 5), the flat knitting machine has the spacer 5 height lower than the optimum value. There is a problem that the needle body 41 is in sliding contact with the needle body 41 or the height of the spacer 5 is higher than the optimum value, so that the gap between the spacer 5 and the needle body 41 becomes large and the needle body 41 shakes up and down during knitting. Does not occur.

  Further, as shown in FIG. 4, the flat knitting machine of the present embodiment is configured to include a movable sinker in which a sinker plate S is swingably supported in the vicinity of the tooth mouth side of the needle plate 2. In this flat knitting machine, since the height of the needle plate 2 is accurately aligned at a predetermined position near the tooth opening g as described above, the position of the sinker plate S can be easily aligned at a desired position.

  A positioning mechanism in the height direction may be provided on the side other than the side of the mouth g. However, in order to suppress the vertical movement of the knitting needle 4, the height of the needle plate 2 is within the range where the spacer 5 is disposed. Since they are preferably aligned, it is preferable to provide a positioning mechanism in the vicinity of the tooth opening g in order to align the heights of the needle plates 2 with high accuracy.

  Further, the needle plate 2 does not have to be provided with the height defining recess 24, but by providing the height defining recess 24, the needle plate 2 can be inserted deeply into the plate groove 10, so that the needle plate 2 in the plate groove 10 In addition to being able to stabilize the standing state, it is not necessary to form the height defining groove 14 deeply when inserting the needle plate 2 deeply.

Embodiment 3
In the first and second embodiments, the flat knitting machine including the wire 61 as the plate fixing member 6 has been described. However, the needle plate 2 is not formed using the wire 61 but the pulling member 60 having an inclined surface that directly contacts the fixing recess 22. Is fixed to the needle bed 1, the number of parts can be reduced. At this time, both surfaces 60b and 22b are brought into contact with each other as the inclined surfaces inclined so that the side surface 60b of the pulling member 60 and the rear end side surface 22b of the fixing recess 22 descend from the rear end side toward the tooth opening g side.

Embodiment 4
In the first and second embodiments, the flat knitting machine including the intermediate support mechanism has been described. However, when performing knitting at a normal knitting speed, for example, about 1.2 to 1.5 m / s, the flat knitting machine that does not include the intermediate support mechanism. It can be a knitting machine.
