Description

  The present invention has a plurality of fixing grooves for accommodating the knitting elements, and these knitting elements are juxtaposed along the longitudinal direction of the bar, each fixing groove having one groove bottom, two groove side surfaces, The present invention relates to a knitting machine bar having one groove opening.

  Such a bar is generally a component of a warp knitting machine. However, the bar can also be used in other stitch forming fiber machines. The knitting elements are mainly compound needles or other knitting needles.

  The invention is illustrated by the following examples of knitting needles.

  A single knitting machine is generally provided with a large number of knitting needles. It is assumed that 500 to 2000 knitting needles per meter are fitted to the bar. During operation, the knitting needle is subjected to a certain amount of wear. Therefore, knitting needles must be changed from time to time.

  The knitting needle is arranged in the fixing groove of the bar. In this case, it is important that the knitting needles are arranged in parallel at a predetermined gauge interval. Furthermore, the alignment of the knitting needles aligned in a straight line after the knitting needles have been fitted will have to be parallel to the longitudinal direction of the bars.

  Since the knitting needles are mass-produced products, the knitting needles that can be produced within the allowable spending range are limited to those that include a certain tolerance. These tolerances may appear, for example, in certain width differences, which may occur, for example, when the knitting needles are made from thin sheets of different lots. As a result, the fixing groove generally has to be formed somewhat larger than the width of the knitting needle. This certainly facilitates the removal of the knitting needle from the fixing groove and the fitting of the knitting needle into the fixing groove, but there is a certain play between the bar and the knitting needle after fitting in the bar. Become.

Therefore, in Patent Document 1, it has been proposed that the stem of the knitting needle has a bulge portion, and this bulge portion forms a certain oversize with respect to the fixing groove. When these knitting needles are pushed into the fixing groove, the bulging part slightly pushes (plastically deforms) or upsets the side surface of the groove, and the knitting needle sits in the fixing groove without any gap. However, this lack of play cannot be maintained over a long period of time or even if it is frequently changed. Further, in the case of mass production, these bulges are always formed at the same position. Therefore, when such a knitting needle is exchanged, there is a sufficient risk that the bulging portion will be seated at a position that has already been pushed away by the bulging portion of the knitting needle that was there last time, and a small play will occur again here.
German Patent No. 4414703

  The object of the present invention is to achieve a satisfactory seating of the knitting element in the bar even after several knitting element changes.

  This problem is solved in the type of bar pointed out at the beginning by the fact that the width of the groove opening in the fixing groove is larger than the width of the groove bottom.

  In other words, the fixing groove of the bar does not have the side surfaces formed in parallel to each other as is generally the case, but the front surface portion, that is, the groove opening portion, is wider than the bottom surface portion, that is, the groove bottom portion. In this case, the knitting needle formed so as to correspond to the fixing groove is automatically positioned when fitted into the fixing groove. That is, it is achieved that the knitting needle always abuts against both groove side surfaces with such a fixing groove, and the knitting needle can be held without gaps in the fixing groove by applying a corresponding holding force from the front surface. That is, there is no need to deform the groove belly portion disposed between the fixing grooves, or to deform the groove belly portion or the knitting needle itself. Rather, the knitting needle and bar can be assembled without wear.

  Mainly, it is a transition that forms the shape of a surface when a transition miracle from a large width to a small width is linked, and this surface exists in at least a part of the depth direction of one groove side surface, and the other groove side surface On the other hand, as it goes from the groove opening to the groove bottom, it is inclined or curved toward the other groove side surface. In the case of an inclined surface or curved surface, the knitting needle is fitted in the fixing groove, and the side surface of the knitting needle is first brought into contact with the groove side surface, so that it is guided slightly in the lateral direction, and the other side surface of the knitting needle is in contact with the other groove side surface. Guided until contact. As a result, both side surfaces of the knitting needle come into contact with the side surfaces of the grooves, and the knitting needles are securely seated in the fixing grooves without any gaps.

  The surface is mainly formed up to the groove bottom. As a result, the surface that contacts the knitting needle in the fixing groove when fitted can be made as large as possible, and the guide surface can be made correspondingly large.

  Preferably, the inclined surface has at least two partial surfaces having different inclination angles. Thereby, in a special case, the fitting and holding of the knitting needle in the fixing groove can be realized more satisfactorily.

  Preferably, the groove side faces are arranged at right angles to the front face of the bar. In that case, the knitting needles are aligned at positions where the side surfaces of the groove are formed in the fixing groove. The knitting needle is already fitted in the fixing groove and contacts the side surface extending at a right angle, and then the knitting needle is pushed into the fixing groove until it contacts the inclined side surface. In that case, the knitting needle is seated in the fixing groove without any gap. Further, when the knitting needle is fitted into the fixing groove so that the knitting needle first contacts the inclined side surface, the knitting needle is guided to the vertically extending side surface by contact with the inclined side surface, and abuts on the vertically extending side surface. Even in that case, seating without gaps is guaranteed.

  In another form, both groove sides have surfaces that are inclined or curved to approach each other. In that case, when the knitting element comes into contact with the first groove side surface, the knitting element is shifted laterally by a slight distance and comes into contact with the other groove side surface. Even in that case, seating without gaps is guaranteed.

  Preferably, both side surfaces of the groove have surfaces extending in parallel with each other in the portion having the largest width. Only a portion of one or both sides is inclined. This is sufficient to assure knitting needle seating without gaps in the anchoring groove.

  Mainly, a knitting element is fitted in at least one fixing groove, and the knitting element has a fixing portion disposed in the fixing groove, and the fixing portion has one front surface, one back surface, and two side surfaces. The fixing portion is formed such that the width of the front surface is larger than the width of the back surface. In that case, the cross section of the knitting element corresponds to the cross section of the fixing groove. The fixing groove can be filled with knitting elements. As a result, the knitting element can be best held in the fixing groove.

  Mainly, the side surface of the knitting element has a shape corresponding to the surface of the groove side surface of the fixing groove at least in a partial surface. In this case, the side surface and the groove side surface can be substantially adjacent to each other in a planar manner, and high fixing stability of the knitting needle is ensured in the fixing groove.

  Preferably, the knitting element protrudes from the fixing groove by a predetermined overhang amount. This has the advantage that the knitting element can be fixedly held in the fixing groove by means of a clamping device, for example a lid.

  It is also advantageous if a predetermined safety distance is provided between the groove bottom and the rear surface of the knitting element. This safety distance is slightly smaller than the overhang amount. With this safety distance, on the other hand, it can be ensured that the knitting element is sufficiently pushed into the fixing groove and abuts on both side surfaces of the groove without any gap. On the other hand, when an excessive force is generated in the process in which the knitting element is fitted in the fixing groove, the excessive force is limited, and even if such a high force is generated in the groove abdomen between the fixing grooves. It will not be deformed beyond tolerance. That is, when such a high force is generated, the knitting element comes into contact with the groove bottom and does not move any further.

  Hereinafter, the present invention will be described based on preferred embodiments in conjunction with the drawings.

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

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

  The knitting machine bar 1 has a plurality of fixing grooves 3 extending in the height direction juxtaposed in a part 2 in a predetermined height direction (vertical direction in FIG. 1), and these fixing grooves 3 are parallel to each other. A plurality of the knitting machine bars 1 are arranged 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 arranged only in the two fixing grooves 3 among the many fixing grooves, but in general, the knitting needles 5 are respectively arranged in all the fixing grooves 3.

  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 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.

  As with a generally known knitting needle, a needle head 8 is provided at one end of the stem 6 and a hook 9 is formed on the needle head 8. A slider is provided on the hook 9 in a form not shown in detail. I can leave. When a thread is hooked on the hook 9 and the stitch is to be inserted, a slider (not shown) can close the hook 9. A bat 10 having a protrusion 11 is formed at the other end of the stem 6, and the protrusion 11 is hooked to the lower end of the portion 2 in the height direction, whereby the knitting needle 5 is additionally fixed to the knitting machine bar 1. To do.

  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 surface 13 is a surface on the side most deeply fitted 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 part 7 are not provided in parallel to each other, but both surfaces 14 and 15 approach each other in the direction from the front surface 12 toward the back surface 13. Inclined in the direction. That is, the cross section of the knitting needle 5 is basically V-shaped at the fixing portion 7.

  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 is configured corresponding 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. Specifically, in each fixing groove 3, the width of the groove opening 17 (the length in the direction from the upper right to the lower left in FIG. 1) is larger than the width of the groove bottom 16, and the two groove side faces 18 and 19 are formed in the groove opening 17. Are inclined toward each other in the direction toward the groove bottom 16. That is, the cross section of the fixing groove 3 is basically V-shaped.

  By the way, the V-shaped configuration as described above automatically aligns the knitting needle 5 when the knitting needle 5 is fitted into the fixing groove 3. One side surface of both side surfaces 14 and 15 of the knitting needle 5 abuts against one of the groove side surfaces 18 and 19 when the knitting needle 5 is fitted in the fixing groove 3 and is applied. 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, 15 abut against the other groove side surfaces 18, 19. For this reason, the center of the knitting needle 5 is automatically arranged so as to be located 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 fitted to the knitting machine bar 1, the knitting needle 5 does not force any deformation on 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 fitted to the knitting machine bar 1. That is, the individual knitting needles 5 can be fixedly held in the knitting machine bar 1 with a lid that will be described in detail below with reference to FIG. 9, and the knitting needles 5 do not require a large cost and have gaps. Without being held in the fixing groove 3.

  The knitting needle 5 can be replaced relatively easily. The knitting needle 5 can be moved toward the front surface 21 of the knitting machine bar 1 by lightly pulling the knitting needle 5 in a direction to be pulled out from the fixing groove 3 to the front side. Then, the new knitting needle 5 can be fixed by being fitted into the fixing groove 3 in the reverse procedure, and it is not necessary to apply a large force during the fitting.

  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 in which the same reference numerals are 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 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 portion 7 of the knitting needle 5 may be considered as various embodiments having the common features of the present invention. Some of these configurations will be described.

  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 plane 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 is at an angle ≠ 90 ° with respect to the front surface 21 of the knitting machine bar 1.

  The knitting needle 5 attached to the knitting machine bar 1 is shown in FIG. The knitting needle 5 has a left side surface 14 in a state of being attached to the fixing groove 3 shown in FIG. 6 corresponding to the configuration (cross-sectional shape) of the fixing groove 3 with respect to 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 but, as described above, is perpendicular to the front surface 21 of the knitting machine bar 1. This is performed on the side surface 18 of the left groove.

  When the knitting needle 5 is fitted into the fixing groove 3, the knitting needle 5 is guided slightly in the lateral direction 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, so that the knitting needle 5 Positioning is performed by the side surface 14 of the contact portion contacting the side surface 18 of the groove.

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

  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), (b), the dimension of the needle gauge is determined by the dimension between the groove side surfaces 18 extending perpendicular to the front surface 21 of the knitting machine bar 1. The

  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 at a right angle 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). 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. Further, the other side surface 15 has a surface 23 which is inclined and extended with respect to the front surface 12 in a portion in the depth direction of the fixing portion 7. This surface 23 comes into contact with the corresponding inclined surface 24 of the groove side surface 19 of the fixing groove 3. The cross section of the fixing groove 3 is formed so as to correspond to the cross section of the knitting needle 5. Specifically, one groove side surface 18 extends perpendicularly to the front surface 21, and the other groove side surface 19 extends parallel to the front surface 21, that is, parallel to the one groove side surface 18. Similarly. In addition, the other groove side surface 19 has a surface that is inclined and extended with respect to the front surface 12 in the rear portion in the depth direction.

  As shown in FIG. 9, when the knitting needle 5 is assembled to the fixing groove 3 in this manner, a safety distance s is formed between the back surface 13 and the groove bottom 16, and in the present embodiment, this safety distance s. Is configured to be dimensionally smaller than the overhang amount 20 between the lid 25 and the front surface 21 of the knitting machine bar 1. 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 the amount of part of the knitting needle protruding forward from the front surface 21 of the knitting machine bar 1 is different due to the difference in the 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.

  FIGS. 10A to 10J show various shapes with different cross sections of the fixing portion 7 of the knitting needle 5. FIGS. 11A to 11J show cross sections of the fixing grooves 3 having different shapes corresponding to the shapes of the fixing portions 7 shown in FIGS. 10A to 10J. However, in general, a fixing groove 3 having the same cross-sectional shape is used for one knitting machine bar 1, and the fixing groove 3 has a fixing portion having a form (shape) corresponding to the form (shape). A knitting needle 5 having 7 is fixed. That is, FIGS. 10A to 10J and FIGS. 11A to 11J illustrate the fixing groove 3 and the fixing portion 7 in various possible embodiments.
