Definitions

  • This invention relates to a knitting needle driving mechanism of a knitting machine.
  • this invention relates to a knitting needle driving mechanism of a knitting machine capable of knitting a predetermined pattern by causing or removing engagement between rising cams for applying a sliding movement to a plurality of knitting needles arranged on a needle bed of the knitting machine and rising cam butts of the knitting needles or rising cam butts of jacks engaging with lower ends of the knitting needles on the basis of a predetermined knitting plan emitted from a controller of a knitting machine main body.
  • a knitting needle driving mechanism for transmitting a patterning procedure memorized in a pattern procedure memory such as a pin drum, a tape, a floppy disk or the like for upward or downward movement of the knitting needle has been heretofore used.
  • a jacquard circular knitting machine is usually comprised of a knitting cylinder 2 having a plurality of knitting needles 3, yarn feed devices 8, and a knitting needle driving mechanism 1 for transmitting a patterning procedure memorized in a patterning procedure memory 4 for vertical movement of the knittintg needles.
  • the knitting cylinder 2 is rotated through a transmitting mechanism 7 by a motor 6.
  • the rotation of the knitting cylinder more exactly, the rotational angle of the knitting cylinder, is detected by a decoder 5 and transmitted to the patterning procedure memory 4.
  • a knitting procedure corresponding to the rotational angle of the knitting cylinder 2 is transferred from the patterning procedure memory 4 to the knitting needle driving mechanism 1.
  • a plurality of yarn 9 is fed through the yarn feed devices 8 to the knitting needles 3.
  • the knitting needle driving mechanism As a knitting needle driving mechanism now in wide use, there is known the knitting needle driving mechanism as shown in Fig. 13, a main portion of which is comprised of a plurality of plates 50 arranged slidably in parallel to each other.
  • the sliding movement of the plates 50 is based on pins on the pin drum or signals emitted from the computer memory.
  • a plate 50 moves toward a center of the knitting cylinder 52, a jack 51 engaging with the lower end of the knitting needle moves toward the center of the knitting clyinder, so that a cam butt provided on the lower portion of the jack 51 is disengaged from a rising cam 54.
  • the vertical movement of the correspond­ing knitting needle is controlled and a knit cloth having the predetermined pattern can be produced.
  • a high speed drive jacquard knitting machine is desired, and it is necessary to speed up the response of the knitting needle driving mechanism to achieve such a high speed drive knitting machine.
  • a knitting needle driving mechanism having the constitution where the plates are slid such as the known knitting needle driving mechanism. It is possible to obtain a high speed knitting machine by increasing the number of the plates slid at the ordinary sliding speed, but the knitting needle driving mechanism then becomes too large, due to the increased number of plates, so that it becomes difficult to arrange the knitting needle driving mechanism in a narrow space outside the knitting machine.
  • the same applicant as the applicant of the present application proposed a knitting needle driving mechanism provided with a plurality of fingers having one end which can be swung, in Japanese Unexamined Patent Publication (Kokai) No. 60-224845.
  • This knitting needle driving mechanism has a rapid response speed compared to the conventional known knitting needle driving mechanism now in wide use, and further is useful in that the knitting needle driving mechanism can be made smaller and the power consumption thereof decreased.
  • the movement of the fingers is caused by applying an attraction force or repelling force from an electromagnet. That is, the sliding movements or the swinging movements of the fingers are performed by applying an electric current to the poles of the electromagnets in such a manner that the poles of the electromagnets are changed from plus to minus, respectively, or vice versa. Therefore, the response speed of the knitting needle driving mechanism activated by the electromagnet has a limit caused by a function of the electromagnet itself, and an optimum high speed of the electromagnet is around 80 cycles per second. Further since the power consumption efficiency of the electromagnet is about 1% and the remainder of the electric current is consumed as heat or the like, there is a problem in that the total consumption of the electric power is extremely high when the knitting needle driving mechanism having the electromagnet is used.
  • the knitting needle driving mechanism having the electromagnet can be used for, e.g., a circular knitting machine for knitting socks, which machine has 240 knitting needles and a rotational speed of 220 r.p.m, it is impossible to apply this knitting needle driving mechanism to a circular knitting machine for knitting panty-hose, wherein the machine has 400 knitting needles and a rotational speed of from 400 r.p.m to 1,000 r.p.m. Therefore, in the existing circumstances, the conventional knitting needle driving mechanism has been used for knitting panty-hose by decreasing the rotational speed of the circular knitting machine to a speed corresponding to an ordinary response speed of the conventional knitting needle driving mechanism.
  • a knitting needle driving mechanism having a high response speed, small size, and low electric power consumption is strongly desired to enable the creation of a high speed jacquard knitting machine.
  • the object of the present invention is to provide a knitting needle driving mechanism having a high response speed, small size, and low electric power consumption for a knitting machine which eliminates the above disadvantage of the conventional known knitting needle driving mechanism.
  • a knitting needle driving mechanism is comprised of a housing, and a plurality of fingers supported in the housing by the rear ends thereof and arranged substantially superimposed at intervals along a sliding direction of the knitting needles.
  • the finger is comprised of a plate having one end provided with an attaching portion to be attached to the housing and another end provided with a guiding portion for guiding a finger butt of the knitting needle or a finger butt of the jack, and a piezo-electric element attached to a face or to both faces of the plate and connected to the controller by means of lead wires.
  • the finger is bent in either an upward direction or a downward direction, or in both directions, about a fulcrum, which is the attaching portion of the finger, to cause or remove engagement between the guiding portion of a front end of the finger and the finger butt of the knitting needle or the finger butt of the jack, when a pulse is input from the controller to the piezo-­electric element in accordance with the procedure corresponding to the predetermined pattern, whereby the formation or the release of engagement between the rising cam and the rising cam butt of the knitting needle or the rising cam butt of the jack is caused by the formation or release of engagement between the guiding portion of the finger and the finger butt of the knitting needle or the finger butt of the jack, and the sliding movement of the knitting needle is thereby defined.
  • the needle bed i.e., a knitting cylinder
  • the knitting needle driving mechanism is fixed to the frame of the knitting machine. Therefore, when the knitting needle driving mechanism according to the present invention is used in the circular knitting machine, it is necessary to constitute the knitting needle driving mechanism in such a manner that the guiding portion of the finger advances towards or retreats from a moving locus of the finger butt of the knitting needle or the finger butt of the jack engaging with a lower end of the knitting needle by the swing motion of the finger, before the corresponding knitting needle moves in front of the knitting needle driving mechanism.
  • the knitting needle driving mechanism according to the present invention can be used in a flat knitting machine.
  • the needle belt is fixed on a frame of the knitting machine, and a slider including the knitting needle driving mechanism and a yarn feed device slides along the needle bed. Therefore, when the knitting needle driving mechanism according to the present invention is used in the flat knitting machine, it is necessary to constitute the knitting needle driving machine in such a manner that the guiding portion of the finger previously advances toward or retreats from a position where the guiding portion of the finger engages with the finger butt of the knitting needle or the finger butt of the jack engaging with a flower end of the knitting needle by the swinging motion of the finger, before the knitting needle driving mechanism slides in front of the corresponding knitting needle.
  • At least one opening is arranged on a portion of the plate of the finger which is provided with the piezo-electric element. Since a weight of the plate having the opening becomes very light, the plate becomes more flexible, so that the plate can be bent by a lower electric voltage. Further, since the piezo-electric element is affixed to the plate with an adhesive, e.g., adhesives of an epoxy group, it is possible to obtain a firm adhesion when the opening is provided on the plate. Most preferably, the piezo-­electric element is affixed to both faces of the plate.
  • any kind of piezo-electric element can be used so long as the piezo-electric element is an element having an inverse piezo-electric effect.
  • a piezo-­electric element of a ceramic constituted from a barium titanate or the like is used, to ensure that a lot quantity of the piezo-electric element having a staple quality can be obtained on an industrial scale. Since it is possible to make the piezo-electric element having a high electrostrictive strain by using a thinner plate, preferably a piezo-electric element having a thickness in the order of from 100 ⁇ m to 200 ⁇ m is used. Further the piezo-electric element may have an elongated shape. A silver paste or the like is baked on both faces of the piezo-electric element to form the electrodes, and these electrodes are connected through lead lines to the controller, respectively.
  • the piezo-electric element is usually affixed to both faces of the plate of the finger by an adhesive.
  • the number of fingers in the knitting needle driving mechanism according to the present invention may be determined in accordance with a required knitting pattern. Since the piezo-electric element has a rapid response speed and it is possible to input a pulse with high frequency to the element, when a pulse of 240 cycles, for example, is input to the element, the knitting needle driving element can drive the knitting needle at a high speed of three times the speed (usually 80 cycles) of a conventional known knitting needle driving mechanism operated by electromagnets. This means that the number of fingers can be decreased to one-third of the number of fingers used in the conventional knitting needle driving mechanism.
  • the knitting needle driving mechanism according to the present invention which has the same number of fingers as the number of fingers of the conventional knitting needle driving mechanism is used, it is possible to knit a jacquard cloth having a complicated pattern such as a three time pattern, compared with a pattern knitted by using the conventional knitting needle driving mechanism, and it is possible to use this knitting needle driving mechanism with a knitting machine in which a product of the number of knitting needles and a rotational speed of the knitting cylinder is three times that of the conventional knitting machine.
  • the finger of the knitting needle driving mechanism according to the present invention is constituted by a thin plate and the piezo-electric element, the height necessary for arranging one finger in the driving mechanism becomes very small and, further, the width of the driving mechanism also becomes very small. Therefore, when the same number of fingers are used in the driving mechanism, the total volume of the driving mechanism becomes very compact. As described hereinbefore, since the knitting needle driving mechanism according to the present invention has a compact volume and a high response speed, this driving mechanism can be also used in a circular knitting machine for knitting panty-hose, in which space it is impossible to attach the conventional knitting needle driving mechanism using the electromagnets with reference to a space to be arranged with the latter driving mechanism.
  • the plate of the finger is of stainless steel and the guiding portion of the finger is formed as a different member made of a hardened steel having a thicker thickness than that of the plate.
  • a rear end of the finger of the stainless steel is held to the housing, and the guiding member made of the hardened steel is connected to a front end of the plate.
  • the guiding member may be connected to the end of the finger by an adhesive, a rivet or the like. Further, it may be possible to achieve the connection between them by providing a groove by which a front end of the plate can be inserted at a rear end of the guiding member.
  • the guiding member Since the guiding member usually impacts on the finger butt of the knitting needle or the jack, abrasion of the guiding member is severe. Further it is necessary to ensure the engagement between the guiding member and the finger butt.
  • the guiding member should be made of hardened steel and have a thick thickness. Preferably, the guiding member has a thickness of about 1 mm.
  • the shape of the end of the finger near to the knitting needle is formed as a hill shape or half hill shape in the plane parallel to the plate of the finger, and it is preferable to make the engagement between the finger butt and the guiding portion of finger along an inclined face of the finger so that the finger butt can be smoothly pushed toward the needle bed of the knitting machine.
  • the controller connected to the piezo-electric elements is a device for memorizing a pattern procedure and inputting a pulse to the plurality of piezo-electric elements on the basis of the memorized pattern procedure, respectively. Since this device is a familiar device in the art, a further detailed explanation thereof will be omitted.
  • Each guiding portion of the plurality of fingers is moved upward or downward on the basis of a signal emitted from the controller to each piezo-electric element of the corresponding finger.
  • a length of the amplitude of the upward and downward movement of the guiding portion of the finger is deter mined in accordance with a height of the rising cam butt in the direction parallel to the movement of the knitting needle.
  • a length of from 1.5 mm to 2.0 mm is usually adopted as the length of amplitude of the upward and downward movement of the guiding portion of the finger.
  • the housing includes a needle bed opposing member elongated in a direction parallel to the sliding direction of the knitting kneedle in the needle bed at a place adjacent to the guiding portion of a plurality of fingers.
  • the needle bed opposing member is provided with a pair of finger-guiding faces for slidably supporting both side faces of the guiding portion of the finger through the predetermined space in the direction perpendicular to a plane including the plate of the finger, and at least one finger butt guiding face extending from the finger guiding face in the direction parallel to the swinging direction of the finger and in the direction away from the guiding portion of the finger.
  • the finger butt guiding face may be formed as a face parallel to the above-mentioned lateral direction, as a face extending from the parallel face, e.g., going toward the needle bed, or as a face extending from the parallel face, e.g., going away from the needle bed.
  • the finger butt of the knitting needle or the jack jumps out in the direction away from the needle bed during a knitting operation, it is possible to push the finger butt into a suitable position by means of the needle bed opposing member having the finger guiding face and finger butt guiding face. Further, since the guiding portion of the finger is supported in the lateral direction by the finger guiding face of the needle bed opposing member, even if there is problem in pushing the finger butt toward the needle bed, the finger is not damaged.
  • the power consumption efficiency of the knitting needle driving mechanism according to the present invention is high, i.e., about 70%, and this value is one to several tens higher than power consumption efficiency of the conventional knitting needle driving mechanism using the electromagnet.
