Description

In the first invention, a needle stem of a knitting element (knitting element) such as a knitting needle has a fixing portion, and the knitting element can be inserted (fixed) into a fixing groove of the knitting machine bar by this fixing portion. The present invention relates to a knitting element such as a knitting needle of a warp knitting machine, in which the fixing portion has one front surface, one back surface, and two side surfaces.
The second aspect of the invention also includes a plurality of fixing grooves arranged in parallel along the longitudinal direction of the knitting machine bar, and a knitting element disposed in at least some of the plurality of fixing grooves. the a, and a respective fixing groove of one groove bottom and two groove sides and one Mizoguchi relates warp knitting machine knitting elements overhang the fixing groove by a specific overhang amount.

  A knitting element such as a knitting needle is known from Patent Document 1, for example.

  In the following, the present invention will be described with reference to a knitting needle, in particular, a compound needle which is a kind thereof. However, the invention is also applicable in other knitting elements that must be secured to the knitting machine bar in a corresponding form. At this time, it is not important whether the knitting needle is configured as a composite needle or a whisker needle, or other types of knitting needles or needles (needles) used at the time of stitch knitting or for stitch knitting, etc. Whether it is an organizational element is not important.

  A knitting needle is a knitting element useful for stitch knitting in textile machines, particularly warp knitting machines. These knitting needles are inserted into the fixing grooves of the knitting machine bar. The arrangement of the knitting needles inserted in this way is such that the knitting needle collides with another knitting element which is attached to another knitting machine bar for knitting (manufacturing) and must move relative to the knitting needle. A relatively high accuracy in gauge spacing is required to avoid this. For the same reason, it is also important that the knitting needles are arranged in a straight line as accurately as possible in parallel with the knitting machine bar.

  However, the knitting needles must be replaced from time to time because of constant wear during operation. In many cases, 500 to 2000 knitting needles are exchanged per meter length of the knitting machine bar. That is, the worker cannot spend an excessive amount of time for inserting a single knitting needle. In addition, it is necessary to avoid as much as possible a situation in which an operator spends time and effort to align the needles after inserting all the knitting needles.

  The aforementioned fixing groove is usually constituted by a rectangular groove in a plan view, and has a needle width dimension, that is, both side surfaces of the needle are laterally (widthwise) between corresponding walls of the fixing groove, There is a small dimensional difference, and this difference creates a certain gap between the knitting needles in the fixing groove. The reason why the dimensional difference occurs between the knitting needle and the fixing groove is that the knitting needle is mass-produced. The existence of such a dimensional difference is inevitable in practice. In particular, when the different knitting needles are different production lots manufactured from different thin plates, the dimensional difference occurs. This is because each thin plate is slightly different in thickness.

In order to realize seating without a gap between the knitting needles in the fixing groove, in Patent Document 1, the needle stem is provided with a bulging portion in the fixing portion, and the bulging portion generates an oversize with respect to the fixing groove. It has been proposed to configure. When such a bulging portion of the knitting needle is pushed into the fixing groove, in this case, the bulging portion is in a state in which the material on the side surface of the groove is slightly pushed away or is in a state of being fitted (fitted state). Should be seated without any gaps. However, such a configuration does not fundamentally solve the problem. This is because, when the knitting needle is worn out, it is replaced with a new one, but the bulging portion of the replaced knitting needle may always be seated at the same position of the fixing groove. That is, when the knitting needle is replaced, there is a certain probability that the new needle bulge will be positioned where the previous bulge of the needle has already pushed the material on the side of the groove. In that case, since plastic deformation has already occurred at the place where the bulging portion of the fixing groove abuts, seating without a gap is no longer secured. When the bulging portion is provided on the needle as described above, there is a risk that the abdomen of the knitting machine bar having the fixing groove is laterally pressurized due to the bulging oversize.
German Patent No. 4414703

  An object of the present invention is to provide a knitting element that can achieve satisfactory seating of a knitting element in a fixed groove even after several replacements, and in particular, to provide a knitting needle that is a kind of knitting element. It is.

  The problem is that, in the knitting element of the type pointed out at the beginning, at least part of the longitudinal direction of the needle stem fixing portion (7) of the knitting element is one of the front surface and the back surface. This is solved by a configuration in which the width of the surface is larger than the width of any one of the remaining surfaces.

  With such a configuration, it is possible to achieve automatic alignment of the knitting elements when they are inserted into the fixing grooves of the knitting machine bar. That is, the cross section of the fixing groove has a form corresponding to the cross section of the fixing portion, and the side surfaces of the fixing portion are at least partially not parallel to each other. According to such a configuration, the knitting element is brought into contact with the groove side surface of the fixing groove when inserted into the fixing groove of the knitting machine bar, and is pressed against the groove side surface of the other fixing groove when inserted further into the back. That is, when the knitting needle is inserted into the fixing groove of the knitting machine bar, neither material wear due to friction nor displacement of the material (plastic deformation) due to deformation of the fixing groove toward the side surface of the groove does not occur. For this reason, the knitting elements can be exchanged repeatedly, and there is no change (deformation) on the geometric shape of the knitting machine bar.

  Mainly, the trajectory of the transition from one of the front surface and the back surface of the knitting needle shaft to the surface with the smaller width forms the surface, that is, the surface with the larger width has the smaller width. If the locus of change of transition to the surface is linked, the transition is performed so as to be in the form of a surface, this surface is present in at least part of the depth direction of one side surface, and this surface is on the other side surface. On the other hand, it is inclined or curved toward the other side surface in the direction from the front surface to the back surface. Here, the “depth direction” is a direction from the front surface to the back surface. Side inclined surface or curved surface is guided and displaced so that the knitting element is in a predetermined position in the lateral direction when the knitting element abuts the corresponding inclined surface or curved surface of the groove side Will be. That is, the alignment operation is performed.

  In that case, it is preferable that the surface formed by the transition is configured to extend to the back surface. With this configuration, the knitting element can be positioned in the fixing groove of the knitting machine bar with a large area of the fixing portion. In addition, the surface on the back side of the knitting element is the surface that is inserted in the innermost part in the fixing groove.

  Preferably, the surface has at least two surfaces having different inclination angles. Such a configuration is suitable, for example, when the knitting element requires a special configuration in which a part of the side surface adjacent to the back surface is an inclined surface having a large inclination angle.

  It is also desirable that only one of the two side surfaces (14, 15) has an inclined surface or a curved surface. In such a configuration, the other side surface extends at a right angle to the longitudinal direction of the knitting machine bar (the direction in which the knitting elements are arranged). In this case, the side surfaces extending at right angles are used for positioning the knitting elements in the fixing grooves of the knitting machine bar. In this way, it is possible to maintain high accuracy of guaranteeing the gauge dimension of the knitting element at a small cost.

  As another configuration of the above configuration, the two side surfaces (14, 15) may have a surface that is inclined or curved so as to approach each other. In particular, when the needle stem of the knitting element is configured symmetrically with respect to the plane passing through the center thereof, it is possible to achieve highly accurate positioning in consideration of the gauge dimension of the knitting element. In such a configuration, the gauge dimension is determined around the center plane of the knitting element.

  Preferably, the two side surfaces (14, 15) are configured to have surfaces extending in parallel with each other in a region close to the surface having the large width. If comprised in this way, when inserting a knitting element in the fixed groove | channel of a knitting machine bar, a fixed guide means will be provided, and the assembly | attachment to the knitting machine bar will become easy.

  Further, as a preferred configuration, one of the two side surfaces (14, 15) is configured to be arranged at right angles to the front surface (12). If comprised in this way, the surface of the front side of a knitting element will extend in parallel with the longitudinal direction (parallel arrangement direction of a knitting element) of a knitting machine bar. Such a configuration can be made by punching at a right angle from one thin plate when manufacturing the knitting element, so that the knitting element can be easily manufactured.

  A further object of the present invention is that, in a knitting machine bar of the type mentioned at the outset, the knitting element is configured as described above, and the fixing groove corresponds to the cross section of the knitting element over at least part of its height. This is solved by having a groove cross section.

  According to such a knitting machine bar, when the corresponding knitting element described above is used, the knitting element can be assembled to the knitting machine bar with a predetermined gauge width with high accuracy, and the assembling can be performed at low cost. Can do. In order to fix the knitting element in the fixing groove as required, it is sufficient to simply insert the knitting element into the fixing groove and fix and hold it there. By such an assembling operation, the knitting elements can be fixed in an automatically aligned state in the fixing groove.

  As a preferred configuration, the groove side surface is configured to extend at right angles to the front surface of the knitting machine bar. In that case, this groove side surface extending perpendicular to the front surface of the knitting machine bar can be used as an auxiliary means for assisting in positioning, which makes it possible to position the knitting elements according to a predetermined gauge dimension at low cost.

  Moreover, as a preferable configuration, a safety distance is provided between the back surface of the knitting element and the groove bottom. This safety distance is actually a small dimension. This safety distance should be sufficiently dimensioned so long as the knitting element is sufficiently pushed into the fixing groove so as to guarantee a seat without a gap between the knitting elements. However, if excessive forces act on the knitting element and try to push the knitting element further toward the back of the fixing groove, the safety distance will be lost, so the knitting element will reach the bottom of the fixing groove relatively soon. Abutting, making it impossible to push the knitting element further into the fixing groove. At the same time, a lateral action higher than the allowable stress on the groove abdomen of the fixing groove is avoided.

  Further, as a preferable configuration, the knitting element is configured to be held in the fixing groove by at least one lid. In such a configuration, the lid generates a holding force. The lid mainly has an elastic layer on the side facing the knitting element, and compensates for small dimensional differences in which the knitting element protrudes from the fixing groove.

  According to the present invention, it is possible to provide a knitting element and a knitting machine bar that can achieve satisfactory seating of a knitting element even after several replacements.

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

  FIG. 1 is a perspective view showing a configuration of a part of a knitting machine bar not shown in detail. Such a bar may have a length of several meters in the longitudinal direction (diagonal lateral direction in FIG. 1).

  The knitting machine bar 1 has a plurality of fixing grooves 3 juxtaposed in a portion 2 indicated by a double arrow in a predetermined height direction (vertical direction in FIG. 1) and extending in the height direction, and these fixing grooves 3 are parallel to each other. A plurality of the knitting machine bars 1 are arranged in parallel in the longitudinal direction. The fixing grooves 3 are separated from each other by a groove abdomen 4.

  A knitting needle 5 which is a kind of knitting element is disposed in the fixing groove 3. In FIG. 1, the knitting needles 5 are illustrated as being disposed only in the two fixing grooves 3 among the many fixing grooves 3, but in general, the knitting needles 5 are respectively disposed in all the fixing grooves 3. The

  The knitting needle 5 shown in FIG. 1 has a form as shown in FIGS. 2A and 2B when viewed from two different directions. Each knitting needle 5 includes a needle stem (stem) 6 having a fixing portion 7. The knitting needle 5 is fixed in the fixing groove 3 of the knitting machine bar 1 by a fixing portion 7.

  Like a generally known knitting needle, it has a needle head 8 following one end of the needle stem 6, and a hook 9 is formed on the needle head 8, and a slider or a closing element is not shown in detail. It can be provided on the hook 9. When the hook 9 is to insert a thread into the stitch, a closing element (not shown) can close the hook 9. The bat 10 formed at the end of the knitting needle 5 opposite to the hook 9 is provided with a protrusion 11, which protrudes into the lower end of the portion 2 in the height direction and puts the knitting needle 5 into the knitting machine bar 1. In addition, it adheres.

  For the purpose described below, the knitting needle 5, more precisely, the fixing part 7 of the knitting needle 5 is provided with one front surface 12, one back surface 13 and two side surfaces 14, 15. The front surface 12 is a surface on the side protruding (visible) from the knitting machine bar 1 when the knitting needle 5 is assembled to the knitting machine bar 1. The back-side surface 13 is the surface that is most deeply inserted into the bottom of the fixing groove 3 of the knitting machine bar 1.

  As can be seen from FIG. 4, both side surfaces 14 and 15 of the fixing portion 7 are not provided in parallel to each other, but both surfaces (side surfaces) as they go from the front surface 12 toward the back surface 13. 14 and 15 incline in the direction which adjoins. That is, the cross section of the knitting needle 5 is basically V-shaped at the fixing portion 7.

  As shown in FIG. 1, each fixing groove 3 has one groove bottom 16, one groove opening (groove opening) 17, and two groove side surfaces 18 and 19 so as to correspond to the configuration (form) of the knitting needle 5. The cross section of the fixing groove 3 is configured to correspond to the cross section of the fixing portion 7 of the knitting needle 5. That is, the inclinations of the side surfaces 14 and 15 of the fixing portion 7 are matched with the inclinations of the groove side surfaces 18 and 19.

  By the way, the V-shaped configuration as described above automatically aligns the knitting needle 5 when the knitting needle 5 is inserted into the fixing groove 3. One side surface of both side surfaces 14 and 15 of the knitting needle 5 abuts on one groove side surface of both the groove side surfaces 18 and 19 when the knitting needle 5 is inserted into the fixing groove 3, When the knitting needle 5 is further pushed into the fixing groove 3, the knitting needle 5 is slightly displaced in the lateral direction, and the remaining side surfaces of the side surfaces 14 and 15 abut against the other groove side surfaces 19 and 18. Therefore, the center of the knitting needle 5 is automatically arranged (aligned) so as to be positioned at the center of the fixing groove 3, and the knitting needle 5 is positioned and fixed in the fixing groove 3 without a gap at that position. . When inserted into the knitting machine bar 1, the knitting needle 5 does not force any deformation of the grooved portion 4 of the knitting machine bar 1 or a part thereof.

  A part of the knitting needle 5 protrudes from the front surface 21 with a small overhang 20 after being inserted into the knitting machine bar 1 (see FIG. 9). That is, the individual knitting needles 5 can be fixedly held in the knitting machine bar 1 with the lid 25 (see FIG. 9) described in detail below based on FIG. 9, and the knitting needles 5 require a large cost. It is held in the fixing groove 3 without any gap.

  The knitting needle 5 can be replaced relatively easily. That is, by applying a simple tensile force to the knitting needle 5 in the direction of pulling it forward from the fixing groove 3, the knitting needle 5 is moved toward the front surface 21 of the knitting machine bar 1, and then the fixing groove 3. Can be taken out from. Then, the new knitting needle 5 can be inserted and fixed in the fixing groove 3 in the reverse procedure, and it is not necessary to apply a large force during the insertion.

  The knitting needle 5 shown in FIG. 2 is suitable as a knitting needle for a Raschel knitting machine. On the other hand, the knitting needle 5 shown in FIG. 3 with the same reference numerals assigned to the same components is suitable as a knitting needle for an automatic warp knitting machine or a warp knitting machine.

  By the way, the embodiment of the cross section of the fixing groove 3 of the knitting machine bar 1 according to the present invention and the cross section of the fixing section 7 of the knitting needle 5 may be various embodiments having the common features of the present invention. However, some of those configurations will be described below.

  In the knitting machine bar 1 of the embodiment different from FIG. 1 shown in FIG. 5, the fixing groove 3 is not formed symmetrically with respect to the virtual center of the fixing groove 3. That is, one groove side surface 18 is arranged at right angles to the front surface 21, and the other groove side surface 19 has an angle ≠ 90 ° (acute angle) with respect to the front surface 21 of the knitting machine bar 1. Yes.

  The knitting needle 5 attached to the knitting machine bar 1 is shown in FIG. The knitting needle 5 corresponds to the structure (cross-sectional shape) of the fixing groove 3, and the left side surface 14 in a state of being attached to the fixing groove 3 illustrated in FIG. 6 is formed on the front surface 12 of the fixing portion 7. The other side surface (right side surface) 15 is configured to form an acute angle with respect to the front surface 12.

  The principle of fixing the knitting needle 5 to the fixing groove 3 is similar (common) to the embodiment shown in FIGS. However, the positioning of the knitting needle 5 in the fixing groove 3 is not performed at the center of the fixing groove 3 in the longitudinal direction of the knitting machine bar 1 (the width direction of the fixing groove 3). 1 on the left groove side 18 which is at right angles to the front face 21.

  When the knitting needle 5 is inserted into the fixing groove 3, a small lateral displacement of the knitting needle 5 is caused by the wedge action between the side surface 15 of the knitting needle 5 and the groove side surface 19 of the fixing groove 3. Positioning is performed by the side surface 14 of the contact portion contacting the side surface 18 of the groove.

  In addition, this configuration is advantageous in that the surface on the side of the knitting needle 5 that abuts the side surface 14 perpendicular to the front surface 12 can be configured to be smooth, as shown in FIG. It becomes clear from b).

  FIG. 8A is a front view of the knitting machine bar 1 shown in FIG. In this embodiment, it can be seen that the dimension of the needle gauge 22 can be determined by the distance between the central surfaces of the fixing grooves 3 arranged side by side. In the case of the configuration shown in FIGS. 5, 6 (a) and 6 (b), depending on the dimension between the side surfaces 18 of the grooves that extend at right angles to the front surface 21 of the knitting machine bar 1, The gauge dimensions are fixed.

  FIG. 8B is a side view showing a configuration from the side face in a state where the knitting needle 5 shown in FIG. 1 is assembled to the knitting machine bar 1, and FIG. 8C is a plan view of FIG.

  As shown in FIG. 9, which is a schematic cross-sectional view, the knitting needle 5 is fixed in the fixing groove 3 of the knitting machine bar 1. In this cross section, one side surface 14 of the knitting needle 5 is disposed so as to extend in the depth direction perpendicular to the front surface 12, and the side surface 14 is the entire depth direction of the fixing portion 7 (from top to bottom in FIG. 9). Extended to the extent to). Similarly, the other side surface 15 of the knitting needle 5 has a portion extending perpendicularly to the front surface 12 of the fixing portion 7, that is, a surface parallel to the side surface 14. In addition, the other side surface 15 has a surface 23 that is extended and inclined with respect to the front-side surface 12 (inclined toward the side 14 in the back) in the back portion of the fixing portion 7 in the depth direction. . This surface 23 comes into contact with the corresponding inclined surface 24 of the groove side surface 19 of the fixing groove 3.

  As shown in FIG. 9, when the knitting needle 5 is assembled to the fixing groove 3 in such a form, a safety distance s is formed between the back surface 13 and the groove bottom 16. The distance s is configured to be smaller than the overhang amount 20 between the lid 25 of the knitting machine bar 1 and the front surface 21. Also, in the case of the knitting needle 5 and the fixing groove 3 according to this embodiment, the same function and effect as those of the above-described embodiment are achieved, and the centering action is also achieved by the surface 23 and the surface 24.

  The lid 25 has an elastic layer 26 on the side facing the knitting machine bar 1, and when the lid 25 is fixed to the knitting machine bar 1, the thickness of the fixing portion 7 of the knitting needle 5 based on tolerance (allowable error) ( Even if a part of the knitting needle protrudes further forward from the front surface 21 of the knitting machine bar 1 due to the difference in thickness or depth of the fixing portion (the vertical dimension in FIG. 9), All the knitting needles 5 can be fixed and held uniformly. However, this difference in thickness is not so large.
