Definitions

  • Patent Literature 1 discloses such a configuration.
  • Patent Literature 1 discloses a flat knitting machine including at least two needle beds facing each other in the front-back direction across a needle bed gap, in which a large number of knitting needles are arranged on the needle bed so as to be movable forward and backward.
  • at least two needle beds facing each other in the front-back direction are configured to be relatively movable (racking).
  • an auxiliary floor (bed-like member) such as a loop pressor or a transfer jack may be provided separately from the needle bed. It is conceivable to individually drive each bed, but an error (a difference in responsiveness or an error in a stop position) in driving of each bed may cause collision between members or hindrance to knitting of a knitted fabric.
  • Patent Literature 1 Japanese Patent No. 3044373
  • a flat knitting machine includes: at least two needle beds facing each other in a front-back direction; a first drive source that is coupled to each of the needle beds and generates a drive force for relatively moving the front and back needle beds in a longitudinal direction; a bed-like member provided to be relatively movable with respect to each of the needle beds; a second drive source that is coupled to the bed-like member and generates a drive force for moving the bed-like member; and a control unit that is capable of controlling operations of the first drive source and the second drive source, in which the second drive source is coupled to each of the needle beds, and in which the control unit is capable of moving each of the needle beds by driving the first drive source, is capable of moving the bed-like member integrally with each of the needle beds along with movement of the second drive source along with movement of each of the needle beds, and is capable of moving the bed-like member relative to each of the needle beds by driving the second drive source.
  • the bed-like member when relatively moving the bed-like member with respect to the needle bed, the bed-like member can be avoided from colliding with other members and causing hindrance to knitting of a knitted fabric.
  • the flat knitting machine may further include a coupling member that is formed so as to extend along each of the needle beds and couples each of the needle beds and the first drive source, and the second drive source may be coupled to the coupling member.
  • the second drive source can be coupled to the needle bed via the coupling member, whereby the degree of freedom of the disposing position of the second drive source can be improved.
  • directions indicated by arrows U, D, F, B, L, and R in the drawings are defined as an upward direction, a downward direction, a forward direction, a backward direction, a left direction, and a right direction, respectively.
  • a flat knitting machine 100 mainly includes needle beds 110, carriages 120, yarn path rails 130, loop pressor beds 140, drive mechanisms 150, and a control unit 160.
  • a pair of front and back carriages 120 are disposed to face the front and back needle beds 110 from above.
  • the front and back carriages 120 are coupled by a bridge 120a disposed to straddle the plurality of yarn path rails 130.
  • the carriage 120 can reciprocate along the longitudinal direction of the needle bed 110 by a servo motor (not illustrated).
  • the carriage 120 is provided with a needle selecting mechanism (not illustrated) and a cam mechanism (not illustrated) for selectively operating the knitting needles 111 of the needle bed 110.
  • FIG. 3 and FIG. 5 hatching is applied to the needle bed 110 and the loop pressor bed 140 in order to clarify each member.
  • the drive mechanism 150 moves the needle bed 110 and the loop pressor bed 140 in the longitudinal direction.
  • one drive mechanism 150 is provided for the needle bed 110 and the loop pressor bed 140 on the front side
  • one drive mechanism 150 is provided for the needle bed 110 and the loop pressor bed 140 on the back side.
  • the drive mechanism 150 mainly includes a first drive source 10, a first sliding plate 20, a second drive source 30, and a second sliding plate 40.
  • the second sliding plate 40 is a longitudinal platelike member, and is provided so as to extend along the body bed 112 of the needle bed 110 with the longitudinal direction of the second sliding plate 40 oriented in the longitudinal direction of the needle bed 110.
  • the second sliding plate 40 is provided above the first sliding plate 20.
  • One end of the second sliding plate 40 is coupled to one end (right end in FIG. 3 ) of the loop pressor bed 140 via an appropriate member.
  • the nut 33 screwed into the ball screw 32 of the second drive source 30 is coupled to a middle portion of the second sliding plate 40 in the longitudinal direction via an intermediate member 70.
  • the control unit 160 drives the first drive motor 11 of the first drive source 10
  • the rotational motion of the ball screw 12 is converted into linear motion
  • the first sliding plate 20 coupled to the ball screw 12 moves in the left-right direction.
  • the needle bed 110 moves in the left-right direction
  • the housing coupled to the first sliding plate 20 and the second drive source 30 accommodated in the housing move in the left-right direction.
  • the second sliding plate 40 coupled to the second drive source 30 moves in the left-right direction
  • the loop pressor bed 140 moves in the left-right direction.
  • control unit 160 drives the second drive motor 31 of the second drive source 30
  • the rotational motion of the ball screw 32 is converted into linear motion, and the second sliding plate 40 coupled to the ball screw 32 moves in the left-right direction.
  • the loop pressor bed 140 moves in the left-right direction.
  • the loop pressor bed 140 can be moved relative to the needle bed 110.
  • the control unit 160 can selectively drive the first drive source 10 and the second drive source 30 based on the knitting program.
  • control unit 160 can move the loop pressor bed 140 integrally with the needle bed 110 without driving the second drive source 30.
  • the control unit 160 By integrally moving the loop pressor bed 140 and the needle bed 110, the influence of the difference in responsiveness and the error in the stop position can be reduced. Therefore, it is possible to avoid the loop pressor 141 from colliding with other members such as the movable sinker.
  • control unit 160 can adjust the relative position of the loop pressor bed 140 with respect to the needle bed 110 by driving the second drive source 30.
  • the loop pressor 141 that has advanced to the needle bed gap S side from interfering with a member such as the movable sinker provided on the needle bed 110 on the opposing side.
  • the front and back loop pressors 141 are at positions facing each other and only the loop pressor 141 on one side can advance, or there is a case where the loop pressor 141 is at a position facing the movable sinker on the opposing side and when the loop pressor 141 is advanced to the needle bed gap S side, the loop pressor 141 interferes with the movable sinker on the opposing side.
  • the loop pressor 141 can be advanced to the needle bed gap S side without interfering with other members.
  • control unit 160 drives the first drive source 10 to move the loop pressor bed 140 integrally with the needle bed 110.
  • control unit 160 can relatively move the loop pressor bed 140 with respect to the needle bed 110 by driving the second drive source 80.
  • the bed-like member of the disclosure is the loop pressor bed 140, but the disclosure is not limited thereto.
  • the bed-like member may be a transfer jack bed provided with a transfer jack for transfer between the front and back needle beds 110.
  • the knitting needle 111 is a latch needle
  • the knitting needle 111 on the opposing side is inserted between the transfer clip (thin plates) provided on one side of the needle main body and the needle main body to perform transfer, but the knitting needle 111 is disposed in a state of being slightly shifted from the center between the sinkers by the transfer clip. Therefore, the formed stitches are not symmetrical.
  • the sinker bed can be relatively moved such that the knitting needle 111 is located at the center between the sinkers.
  • the left and right uniform stitches can be formed.
  • the range in which the loop pressor bed 140 is relatively movable with respect to the needle bed 110 is set to be within 1 pitch, but any value can be set according to the type of the bed-like member of the disclosure.
  • the range in which the bed-like member is relatively movable with respect to the needle bed 110 may be set to be smaller than the range in which the needle bed 110 is relatively movable.
