Abstract

PROBLEM TO BE SOLVED: To provide a flat knitting machine with a stitch suppression plate which can release stitch even if stitch is inserted between a parallel part of a stitch suppression groove of the stitch suppression plate and a needle bed by biting.SOLUTION: A stitch suppression plate 1 has a step part 7 between a parallel part 5 and bias part 6 of a stitch suppression groove 2. The stitch led in the stitch suppression groove 2 is suppressed between the parallel part 5 and an inside edge 3a even if a knitting needle moves. However, the suppressed stitch repeats companion motion with the motion of the knitting needle. When the yarn thins down, as a result of the companion motion, insertion of the yarn might be generated between the parallel part 5 and a needle bed. Even if the insertion is generated at the parallel part 5, the inserted stitch can be released by dropping the stitch when passing the step part 7.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a flat knitting machine provided with a stitch deterrent plate that can be knitted by overlapping finger crotches of gloves.

  Conventionally, of flat knitting machines with needle beds at the front and back, flat knitting machines with stitch deterrent plates, also called razors, are knitted so that the crotch of gloves is stacked and no holes are opened between the finger bags. (See, for example, Patent Documents 1 and 2). Such flat knitting machines are widely used for knitting gloves for various operations efficiently and at low cost.

  The stitch restraining plate is in contact with the bottom surface side of the knitting needle that advances and retreats to and from the lower portion of the needle bed in the vicinity of the mouth where the front and rear needle beds face each other, and is movable in the knitting width direction (FIG. 2). 3). The stitch restraining plate (knitting mouth presser plate) is provided with a stitch restraining groove (knitting mouth latching groove) that extends slightly to one side of the knitting width and opens slightly away from the tooth opening. The locking piece extends to one side of the knitting width on the tooth opening side of the stitch suppression groove (see FIG. 1 of Patent Document 1). When knitting finger bags that are sequentially adjacent to the other side of the knitting width, the knitting needle at the end on one side of the knitting width is stitched in the section where crotch-stacking is performed with the finger bag on the other side after knitting the finger bag on one side The stitch restraining plate is moved from the other side of the knitting width to the one side so as to be positioned near the back end of the restraining groove. The stitch in the section that is the other side of the knitting width with the finger bag on one side is guided to the stitch suppression groove at the tip of the locking piece, and the stitch at the end where crotch overlaps is suppressed at the back end, and the suppression With an effective knitting needle, the stitch of the next finger bag can be knitted without any problem. If the stitch restraining plate is moved to the other side of the knitting width after knitting the next finger bag, the stitch that has been restrained by the stitch restraining groove returns to the top tooth facing the tooth opening along the inclination of the skewed portion. . In the knitting needle that has been restrained by the stitch restraining groove at the end of the finger bag on one side, the stitch knitted as the end of the finger bag on the other side is also locked. It becomes.

  The stitch restraining plate comes into contact with the bottom side of the knitting needle that advances and retreats to the mouth for knitting, and acts to fasten the knitted stitch to the needle stem in the stitch restraining groove. There is a risk of biting between the knitting needle and the needle bed. In Patent Document 1, the end surface of the skewed portion is made an inclined surface having an acute angle gradient with respect to the upper surface to make it difficult for the stitch to be bitten. In Patent Document 2, the stitch restraining plate is regulated so as not to be separated from the needle bed, and the stitch is made difficult to be bitten.

  In recent years, gloves for knitting with thin and elastic knitting yarns have been demanded for precision work and the like. Stretchable knitting yarns form stitches in a further thinned state due to tension applied during knitting. When such a knitting yarn is used, there is an increased risk of biting at the parallel portion extending in the knitting width direction in the stitch suppression groove of the stitch suppression plate.

  An object of the present invention is to provide a flat knitting machine provided with a stitch suppression plate that allows a stitch to be released even if the stitch is pinched between a parallel portion of a stitch suppression groove of a stitch suppression plate and a needle bed. That is.

FIG. 2 is a partial plan view, a front view, and a side sectional view showing a configuration in the vicinity of the stitch suppression groove 2 in the stitch suppression plate 1 of FIG. FIG. 3 is a side sectional view showing a schematic configuration of the flat knitting machine 10 provided with the stitch suppression plate of FIG. FIG. 4 is a plan view, a front view, and a right side view showing the configuration of the needle plate 12 used in the flat knitting machine 10 of FIG. FIG. 5 is a partial plan view, a front view, and a right side view showing the configuration near the tip of the needle plate 12 of FIG.

  Hereinafter, the structure of the flat knitting machine 10 provided with the stitch suppression plate as one embodiment of the present invention will be described with reference to FIGS. For convenience of explanation, portions that are not described in the drawings to be described may be referred to with reference numerals described in other drawings.

  FIG. 1 shows a schematic configuration of the stitch suppression plate 1. In the use state of the stitch suppression plate 1 described later in FIG. 3, the horizontal direction in FIG. 1 is the knitting width direction, the vertical direction is the advancing / retreating direction of the knitting needle, and the upper side is a flat top tooth 1a facing the tooth opening. The stitch restraining plate 1 has a plate-like shape elongated in the knitting width direction, and the back surface side in the drawing abuts against the bottom surface side of the knitting needle 13 and can reciprocate in the knitting width direction. The stitch restraining plate 1 is formed with a stitch restraining groove 2 that is used when knitting a crotch overlap where a part of stitches of a finger crotch overlaps between adjacent finger bags. The stitch-inhibiting groove 2 is formed by a locking piece 3 that is provided so as to extend to the right side in the drawing in order to suppress the stitch of the finger bag that has been previously knitted, and to the right in the drawing. The inner edge 3a, the inner edge 3a, the back end 4 connected to the other side of the knitting width, and the parallel part 5 connected to the inner edge 3a and facing the inner edge 3a at a distance from the tooth opening. , Generally surrounded by a U-shape.

  The stitch restraining plate 1 of the present embodiment has a skewed portion 6 on one side of the parallel portion 5, and is inclined between the parallel portion 5 and the skewed portion 6 in the downward direction of the figure, that is, in a direction away from the tooth opening. A stepped portion 7 is formed. The skewed portion 6 is separated from the tooth opening from the start end 6b at a position spaced from the tip 3b of the locking piece 3 to one of the knitting widths to the end end 6b connected to the stepped portion 7 at the other knitting width. Inclined to. As the height of the stepped portion 7, the parallel portion 5 to the end end 6b are separated from the tooth opening by the same degree as the diameter of the knitting yarn.

  However, with respect to the knitting width direction, basic dimensions such as the length that the locking piece 3 extends and the length from the back end 4 of the stitch suppression groove 2 to the start end 6a of the skewed portion 6 are the conventional stitches. Same as deterrence plate. In a flat knitting machine including a stitch suppression plate for glove knitting, a mechanism for moving the stitch suppression plate in the knitting width direction in conjunction with the knitting of the finger pouch is provided. By making the basic dimensions the same as those of the conventional stitch suppression plate, the stitch suppression plate 1 of the present embodiment can be driven in the same manner by a conventional mechanism. Alternatively, the stepped portion 7 may be located on one side of the knitting width with respect to the tip 3b of the locking piece 3 and the parallel portion 5 may be formed up to the vicinity of the tip 3b of the locking piece 3.

  The stitch guided into the stitch restraining groove 2 by the movement of the stitch restraining plate 1 is restrained between the parallel portion 5 and the inner edge 3a of the locking piece 3 facing the parallel portion 5 even if the knitting needle advances or retreats. However, the stitches to be restrained are repeatedly moved along with the movement of the knitting needle when the knitting needle advances and retracts the hook at the tip of the knitting needle to knitting the stitch of the new finger pouch. When the knitting yarn becomes thin, the knitting yarn may be caught between the parallel portion 5 and the needle bed as a result of the accompanying movement. In the present embodiment, even if pinching occurs in the parallel portion 5, the stitches that have been pinched are pulled out when passing through the stepped portion 7 provided with a height difference, and thus can be released.

  As shown in FIG. 1 and FIG. 2 of Patent Document 1, conventionally, the stepped portion 7 is not provided, and the skewed portion is formed up to the vicinity of the tip of the locking piece portion. When the crotch knitting is completed, the stitch suppression plate 1 is moved to the other knitting width. The stitch that has been restrained in the stitch restraining groove 2 rises along the skewed portion 6 and returns to the flat top tooth 1a when the start end 6a of the skewed portion 6 is exceeded. In the present embodiment, the stepped portion 7 is provided on the other side of the knitting width with respect to the tip 3 b of the locking piece portion 3. The skewed portion 6 following the stepped portion 7 is also formed until it enters the other side in the knitting width direction from the tip 3b of the locking piece portion 3. Further, in the case of the present embodiment, the position of the parallel portion 5 is brought closer to the inner edge 3a side and the stitch suppression groove 2 is made narrower than before, so that the inclination angle of the skew portion 6 can be made slower than before. The burden on the stitches moving along the skew portion 6 can be reduced. Even when the position of the parallel portion 5 is the same as that of the conventional stitch suppression groove and the stitch suppression groove is wide, if the step portion 7 is provided between the parallel portion 5 and the skew portion 6, the stitch sandwiched between the parallel portions 5 Can be released by the stepped portion 7.

  2 shows the configuration of the stitch restraining plate 1 in FIG. 1 in the vicinity of the stitch restraining groove 2, in a plan view of (a), a front view of (b), and side sectional views of (c) and (d). Show. In addition, (c) and (d) respectively show the cross-sectional configurations viewed from the cutting plane lines CC and DD shown in (b).

  As shown in (c), the distance between the inner edge 3a and the parallel part 5 in the stitch restraining groove 2 is narrow on the back side Ai, which is the one side where the stitch restraining plate 1 abuts against the back side of the knitting needle, and on the other side. Widens on side Ao. As will be described later with reference to FIG. 3, the needle bed is raised on the side of the mouth, and the front and back needle beds face each other in a letter C shape across the mouth. The stitch restraining plate 1 in use is arranged so that the back side is the upper surface and the top teeth 1a are the mouth side, and is parallel to the knitting needle. The knitted fabric that hangs down below the mouth of the knitting stitches in the stitch restraining groove 2 has a larger distance between the inner edge 3a and the parallel portion 5 on the other side opposite to the one side that contacts the back side of the knitting needle. Therefore, it can hang down straight without being rubbed against the member, and can be locked with a reduced load.

  As shown in (d), the oblique portion 6 is configured such that the cross-sectional shape from the back surface side to the front surface side is an inclined surface in order to reduce the plate thickness of the upper edge portion 6c on the back surface side. By making the skewed portion 6 that guides the stitches back to the top teeth 1a after the finger crotch knitting as an inclined surface and reducing the plate thickness of the upper edge portion 6c, the stitches are smoothly guided and made difficult to wind. Can do.

  FIG. 3 shows a schematic configuration of the flat knitting machine 10 provided with the stitch suppression plate of FIG. The needle bed of the flat knitting machine 10 is formed by standing a needle plate 12 on a substrate 11. The needle plate 12 is provided at regular intervals in the knitting width direction, which is the depth direction in the figure, and a needle groove for accommodating the knitting needle 13 is formed between the needle plates 12. Although such a needle bed is opposed to form a pair across the mouth 10a, only one needle bed is shown. In the needle groove, the knitting needle 13 advances and retracts the hook 13a at the tip to the tooth opening 10a, and forms a stitch with the knitting yarn received by the hook 13a. The knitted stitches are connected to a knitted fabric 20 that hangs down from the mouth 10a. The knitting needle 13 is pressed from above by a band 14 so that it does not come out of the needle groove. The needle plate 12 is provided with a tip end portion 12a on the side of the tooth opening 10a and a band receiving portion 12b on the band 14 portion.

  The stitch restraining plate 1 is provided on the side of the tooth opening 10a of the substrate 11, and is held so as to come into contact with the bottom surface side of the knitting needle 13 by the back surface receiving member 15 from the back surface side and the upper receiving member 16 from above. However, the upper receiving member 16 is attached to the attachment portion 11 a of the substrate 11. The attachment portion 11a is a needle bed and is formed outside a section where the needle plate 12 is erected and the knitting needle 13 is accommodated. Since the stitch restraining groove 2 has a cross-sectional shape as shown in FIG. 2C, the burden applied to the knitted fabric 20 connected to the stitches to be locked can be lowered to the tooth opening 10a. Similarly, the inclination of the skewed portion 6 shown in the cross section of FIG. 2D also contributes to smoothly suspending the knitted fabric 20 at the tooth opening 10a.

  FIG. 4 shows the configuration of the needle plate 12 used in the flat knitting machine 10 of FIG. FIG. 5 shows a configuration near the tip of the needle plate 12 of FIG. The needle plate 12 is held by fitting the lower portion 12 c into a groove provided in the substrate 11. The distal end portion 12a is located closer to the tooth opening 10a than the substrate 11, and has a relief processing portion 12d at the lower portion of the front end. The relief processing portion 12d makes it easy to form a double stitch smoothly with the newly knitted stitch by the stitches locked in the stitch restraining groove 2 being pulled out to the top teeth 1a along the skewed portion 6.
