Definitions

  • This invention relates to a knitting needle driving mechanism of a circular knitting machine.
  • this invention relates to the knitting needle driving mechanism of a circular knitting machine capable of knitting a predetermined pattern by making or removing engagement between raising cams for applying vertical movement to a plurality of knitting needles on a circular cylinder of the circular knitting machine and cam butts of jacks engaging with lower ends of the knitting needles on the basis of a predetermined knitting plan.
  • a jacquard circular knitting machine is 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 knitting 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.
  • the patterning procedure memory 4 usually consists of a pin drum or a computer memory.
  • a plurality of yarn 9 is fed through the yarn feed devices 8 to the knitting needles 3.
  • the knitting needle driving mechanism as shown in Fig. 9, a main portion of which is comprised of a plurality of plates 60 arranged slidably in parallel to each other.
  • the plates 60 slide base on pins on the pin drum or signals emitted from the computer memory.
  • a jack 61 engaging the lower end of the knitting needle moves toward the center of the knitting cylinder, so that a cam butt provided on the lower portion of the jack 61 is disengaged from a rising cam 64.
  • the vertical movement of the corresponding knitting is controlled and a knit cloth having the predetermined pattern can be made.
  • French Patent 1.564.603 describes a knitting needle driving mechanism having a plurality of fingers arranged substantially superimposed at intervals along the sliding direction of the knitting needles and capable of swinging in the sliding direction of the knitting needles by being pivoted at points near their central portions, and an electromagnetic finger operating device for selectively swinging the corresponding fingers.
  • said electromagnetic finger operating device comprises U-shaped polar expansions.
  • the permanent magnet abuts against one of the two polar expansions of said electromagnetic finger operating device and said polar expansions operate as mechanical abutments which stop the swinging movement of said swinging finger.
  • the fingers would have to be stronger, and therefore could no longer be so small.
  • the operating speed may not exceed certain well-defined limits.
  • the object of the present invention is to provide a knitting needle driving mechanism having a small size and high response speed for a circular knitting machine.
  • a knitting needle driving mechanism comprising a plurality of fingers arranged substantially
  • a knitting needle driving mechanism comprising a plurality of fingers arranged substantially superimposed at intervals along the sliding direction of the knitting needles and capable of swinging in the sliding direction of the knitting needles by being pivoted at points near their central portions, and an electromagnetic finger operating device for selectively swinging the corresponding fingers, according to the invention, said electromagnetic finger operating device is arranged at a location behind the fingers.
  • Permanent magnets are provided on ends of the fingers remote from the knitting cylinder such that the lines connecting the two poles substantially correspond to the lengthwise directions of the fingers.
  • the ends of the fingers near to the knitting cylinder have formed thereon pushing surfaces having a hill shape or a half hill shape in the horizontal plane and a predetermined thickness in the vertical direction.
  • the electromagnetic finger operating device includes a plurality of electromagnets, the S-poles and N-poles of which are attached on the housing.
  • the S-poles and the N-poles of the electromagnets are positioned at intervals in the vertical direction so as to substantially face the end surfaces of the permanent magnets, of the fingers in the upper position and lower position of the swinging movement of the fingers.
  • the housing includes a plurality of pivots supporting the fingers at the center portions thereof and a pair of finger guides slidably guiding in the vertical direction the two side faces, in the horizontal direction, of the plurality of fingers at the pushing side.
  • the surfaces of the finger guides facing the knitting cylinder are parallel to the lengthwise direction of the knitting cylinder and extend in direction away from the fingers to form lead surfaces for finger butts of jacks abutting the lower ends of the knitting needles.
  • the electromagnets of the electromagnetic finger operating device are supplied selectively with plus or minus currents in accordance with a predetermined plan, whereby the fingers swing and select the engagement between the pushing surfaces of the fingers and the finger butts of the jacks. The engagement between a raising cams and cam butts of the jacks is thereby selected and knitting of the predetermined pattern becomes possible.
  • the knitting needle driving mechanism in accordance with the present invention is comprised of a plurality of swingable fingers as described hereinbefore and the swinging movement of the fingers is performed by an attractive force and a repelling force of electromagnets against the permanent magnets arranged on the ends of the fingers, the knitting needle driving mechanism can be operated at a high response speed compared with the conventional known knitting needle driving mechanism operated by the sliding movement of the fingers. Further, since the construction of the device of the present invention is simple, the device can be manufactured at low cost. Also, it is possible to save on electric power consumed in operating the device.
  • the finger guides of the knitting needle driving mechanism have formed thereon lead surfaces for the finger butts of the jacks engaging the lower ends of the knitting needles so that any butt protruding outward of the knitting cylinder for any reason is corrected in advance by the lead surfaces. Consequently, there is no change that a finger butt of a jack will directly abut a finger, thus minimizing the chance of damage to the fingers.
  • the relative position between the fingers and the finger guides be determined such that, at the swinging position in which the pushing surfaces of the fingers engage with the finger butts of the jacks abutting the lower ends of the knitting needles, the two end edges of the pushing surfaces of the fingers, i.e., the hill shape portions, furthest from the knitting cylinder, or the end edge of half hill shaped portions remote from the knitting cylinder, be positioned in the same plane as the finger butt lead surfaces of the finger guides or move inward of the finger guides than the lead surfaces.
  • the knitting needle driving mechanism having the aforesaid construction enables smooth contact of the finger butts positioned on the lead surfaces with the fingers, so the risk of damage to the fingers can be reduced and, as a result, the durability of the knitting needle driving mechanism can be significantly increased.
  • the knitting needle driving mechanism in accordance with the present invention can be used when the circular knitting cylinder is rotated in the normal direction and the reverse direction.
  • pushing surfaces formed in a half hill shape may be used.
  • the knitting needle driving mechanism of the embodiment is comprised of eight fingers 11, an electromagnetic finger operating device 30 arranged behind the fingers 11, and a housing 20 supporting the eight fingers 11 and the electromagnetic finger operating device 30.
  • eight fingers are shown in the knitting needle driving mechanism according to the present embodiment, the number of fingers is not particularly limited. At least 16 fingers are used in conventional (sliding movement type) knitting needle driving mechanisms.
  • a knitting needle driving mechanism with a small number of fingers is preferable, because it is possible to make the external dimensions smaller. Since, in the embodiment according to the present invention, the operation of the knitting needle driving mechanism can be made high speed, as described hereinafter, it is possible to form the knitting needle driving mechanism with eight fingers. Incidentally, the ideal number of fingers in a knitting needle driving mechanism is just one.
  • a finger 1 is comprised of a finger central portion 19 supported rotatively by a pivot 16, a first arm 12 and a second arm 13 extending from the finger central portion 19 to the two sides, a pushing member 14 attached to a top end of the first arm 12, and a permanent magnet 17 attached to a top end of the second arm 13.
  • the top end of the pushing member 14 is substantially formed in a hill shape in the horizontal plane including the lengthwise axis of the finger 11 and inclined surfaces thereof form pushing surfaces 15, 15'.
  • the permanent magnet 17 is formed such that the line connecting the two poles, i.e., S-pole and N-pole, corresponds to the lengthwise direction of the finger 11.
  • a pair of electromagnets is arranged for each finger 11.
  • the pair of the electromagnets includes two electromagnetic coils 33 and 34 and electromagnet ends 31 and 35 provided on each electromagnetic coil 33 and 34 to form a U-shape electromagnetic coil, as illustrated in Fig. 4.
  • Fig. 4 shows that the two electromagnet ends 31 and 35 connected with the electromagnetic coils 33 and 34 by leading wires, this is for convenience in explanation.
  • the electromagnet ends are the ends of the core of the electromagnetic coil.
  • the electromagnet ends 31 and 35 are arranged in a rear vertical plate 22 of the housing 20, as illustrated in Fig. 3. Namely, the electromagnet ends 31a and 35a in Fig.
  • FIGS. 3 are ends of the core of the pair of electromagnetic coil 33a and 34a.
  • each electromagnetic coil When current flows to each electromagnetic coil to energize them, it is possible to reverse the states, e.g., change a plus state of the electromagnet end 35a and a minus state of the electromagnet end 31a a to a minus state of the electromagnet end 35a and a plus state of the electromagnet end 31 a, by changing the direction of the electric current.
  • the change of the direction of the electric current is usually performed by means of transistors, so that the change between the plus state and the minus state of the electromagnet surface can be performed at an extreme high speed.
  • the pushing surfaces 15 and 15' are arranged at intervals in the vertical direction in Fig. 2 (which coincides with the sliding direction of the knitting needles).
  • four fingers of the eight fingers are pivotably supported at a front side and the other four fingers (not shown in Fig. 1) at the back side by forming the pushing member 14 of the rear portion of the pushing surface 15 in a sickle-like shape as illustrated in Fig. 4.
  • the electromagnet surfaces corresponding to the permanent magnets 17 on the ends of the eight fingers are arranged such that four pairs are at the left and four pairs are at the right.
  • the eight finger central portions 19 are separated into two groups; a left 19a, 19b, 19c, and 19d and a right 19e, 19f, 19g and 19h in Fig. 2. Consequently, the finger central portions 19 and the pivots 16 can be designed to dimensions sufficient to withstand the high speed sliding of the fingers 11 and, as a result the durability of the knitting needle driving mechanism according to the present invention can be increased. On the other hand, it is possible to make a knitting needle driving mechanism having the same strength with a smaller overall size.
  • the space between the permanent magnets 17 and the electromagnetic ends 31 and 35 of the electromagnetic finger drawing mechanism 30 be such that the two approach each other without actual contact.
  • the housing 20 includes a pivot support member (not shown) extending in the vertical direction in the roughly central portion of the housing 20.
  • the pivot support member supports four pivots 16 on both sides thereof.
  • the housing includes a front vertical plate, i.e., a finger guide 21.
  • the finger guide 21 is provided with an opening 23 having a substantially rectangular shape.
  • the pushing surfaces 15 and 15' of the fingers 11 protrude into the opening 23.
  • the opening 23 may be formed as a slit extending from a top end to a lower end of the housing 20.
  • the relative position between the finger guide 21 and the pivots 16 supporting the fingers 11 is determined such that the space between the side walls 25 and 25' of the opening 23 (see Fig. 2 and 4) is set slightly larger than the distance between the side walls 55 and 55' of the pushing member 14 and such that at least one portion of the pushing surface 15 protrudes from the lead surface 24 of the finger guide 21.
  • Figs. 5 and 6 40 is a jack.
  • the jack 40 is provided with a finger butt 41 and a cam butt 42.
  • the S-pole at the end of the permanent magnet 17 of the finger 11 faces an electromagnet end 31, the end face of which is an N-pole, so that the finger 11 is kept in the horizontal plane in Fig. 5.
  • the finger butt 42 of the jack 40 on the knitting cylinder (not shown) abuts the pushing surface 15 of the finger 11, so that the jack 40 is turned in the counterclockwise direction. Therefore, the cam butt 42 of the lower end of the jack 40 does not abut a raising cam 43 arranged on a machine frame of the circular knitting machine, so that the jack 40 and the knitting needle (not shown) engaging the jack 40 do not receive a raising movement caused by the raising cam 43.
  • the relative position between the pushing surface 15 of the finger 11 and the finger butt 41 of the jack 40 may be constituted, conversely to Fig. 6, so that engagement between the finger butt 41 and the pushing surface 15 is released by upward movement of the pushing surface 15.
  • the swinging movement of the finger 11 is performed by changing the direction of the electric current toward the electromagnetic coils 33 and 34. Since the change of the direction of the electric current is performed by a usual transistor, it can be effected at a high speed. Since the finger can change in position by a swinging movement about the pivot 16, the finger rapidly responds to the attraction between different poles of the electromagnets and the repulsion between the same poles of the electromagnets to change in position. Consequently, the pushing surface of the finger can be inserted to or removed from a position engaging with the finger butt of the jack at a higher speed compared with any conventional known knitting needle driving mechanism.
  • the pushing member 14 may be formed in a hill shape having inclined pushing surfaces 15 and 15' on its two sides, as illustrated in Fig. 7(a) (b), (c), (d) and (e), or in a half hill shape having an inclined pushing surface 15' on only one side, as illustrated in Fig. 7(f).
  • a hill shape having inclined pushing surfaces 15 and 15' on its two sides
  • Fig. 7(a) (b), (c), (d) and (e)
  • a half hill shape having an inclined pushing surface 15' on only one side
  • the relative position between the finger guide 21 and the pushing member 14 may be determined such that the pushing surfaces 15 and 15' of the pushing member 14 are completely exposed from the lead surface 24 and 24' and further portions of side walls 55 and 55' of the pushing member 14 are exposed from the lead surface 24 and 24' as illustrated in Fig. (e). However, it is preferable that the relative position between the finger guide 21 and the pushing member 14 be determined such that points 56 and 56', at which the pushing surfaces 15 and 15' meet the side walls 55 and 55', are arranged within the lead surfaces 24 and 24' as illustrated in Fig. 7(a); or the points 56 and 56' coincide with the lead surfaces 24 and 24', as illustrated in Fig. 7(b). When the relative position between them is determined as illustrated in Fig.
  • the jack butt 41 advancing toward the pushing surfaces 15 and 15' under the guide of the lead surface 24 or 24' can ride on the pushing surface 15 or 15' without receiving any resistance and can move by being pushed by the pushing surface 15 or 15', more concretely, by the jack butt being pushed toward an axis of the knitting cylinder.
  • the lead surfaces 24 and 24' serve to push the jack to a suitable level when the jack jumps out in the radial direction of the knitting cylinder by centrifugal force itself or damage itself, the lead surface can prevent the finger butt from damaging the finger of the knitting needle driving mechanism.
  • the angle of inclination of the lead surfaces 24 and 24' may be such that the lead surfaces 24 and 24' are in the horizontal plane in Fig. 7, as illustrated in Fig. 7(a) and Fig. 7(b) are inclined outward as illustrated in Fig. 7(c), or inclined inward as illustrated in Fig. 7(d).
  • the position of Fig. 7(c) helps to slowly push in a protruding jack, and the position of Fig. (d) helps to push in an abnormally protruding jack.
  • the leads surfaces 24 and 24' of the finger guide 21 are formed as flat planes, the shape of the lead surfaces is not limited to a flat plane and may be formed as an arc-like shape.
  • the knitting needle driving device Since the knitting needle driving device according to the present invention is constituted as described hereinbefore, the movement of the pushing surface of a finger for selecting a needle is very speedy. Therefore, it is possible to make the knitting needle driving mechanism small by decreasing the number of fingers compared with the conventional knitting needle driving mechanism. Further since the construction of the device is simple, the device according to the present invention has advantages of low cost manufacture of the device and significant savings in power consumption.

Abstract

Dispositif de sélection d'aiguilles pour machines à tricoter circulaires, comprenant une pluralité de doigts dont chacun est supporté de manière pivotante à proximité de sa partie centrale, et dont chacun est pourvu à une extrémité d'un aimant permanent et à l'autre extrémité d'une surface de poussoir; le dispositif comprend en outre une bobine électromagnétique en U possédant des pôles S et N disposés verticalement et opposés à l'aimant permanent. Lorsqu'un courant électrique est appliqué à la bobine électromagnétique sélectivement vers l'avant et vers l'arrière par rapport à un certain plan, les doigts sont déplacés de manière pivotante, de sorte que les surfaces de poussoir des doigts et un aboutement de tringle à crochet pouvant être engagé par les doigts s'engagent entre eux sélectivement. Une came de levage dans la machine à tricoter circulaire et un aboutement sur la tringle à crochet pouvant être engagé par la came s'engagent l'un dans l'autre sélectivement, ce qui permet d'effectuer un tricotage selon un motif prédéterminé.
