Definitions

  • This invention relates to a trick plate spacing changer for double raschel machines.
  • a spacing between front and rear opposite rows of knitting needles should be changed when the thickness of a fabric to be knitted is changed. This requires change of a spacing between front and rear trick plates contingent on the knitting needles.
  • the applicant has proposed and filed the JP-A-2000-80545 for the apparatus for changing the spacing between front and rear trick plates.
  • an eccentric mechanism provided with locking means is connected to an end of each connecting rod connected to respective supporting levers for supporting front and rear opposite trick plates.
  • the locking means would be unlocked when a spacing between the trick plates is to be changed, and a handle attached to the eccentric mechanism is rotated as to change a position of the connecting rod.
  • the supporting lever is rotated as to change a position of the trick plates held at the distal ends.
  • a desired trick plate spacing is obtained through such procedure.
  • the trick plate pivots about an axis of the supporting lever to change in position.
  • a distal end of the trick plate is even slightly shifted in a stroke direction relative to distal ends of the knitting needles. If such shift is left as it is, a condition of pulling from a loop in knitting changes, resulting in trouble or disadvantage in knitting.
  • stroke of knitting needles has to be changed or adjusted, after changing the trick plate spacing. This makes a procedure for changing the trick plate spacing to be troublesome.
  • a trick plate spacing changer which can resolve the above problems, for a double raschel machine that is comprised of : front and rear, two rows of knitting needles; front and rear trick plates contingent on the front and rear rows of knitting needles; front and rear intermediate frames respectively supporting the front and rear rows of knitting needles and the trick plates in a knitting-allowing manner; and a front pedestal and a rear pedestal on which the front and rear intermediate frames are respectively erected and fixed, characterized in that: means or mechanism for linearly moving the front pedestal and the rear pedestal toward and away from each other are provided on both of the front and rear pedestals so as to enable changing of spacing between the front and rear trick plates together with spacing between the rows of knitting needles.
  • the trick plate spacing changer linearly moving the front pedestal and the rear pedestal toward or away from each other by means of said means for moving allows the spacing between the front and rear trick plates to be easily changed. Furthermore, the whole parts on the front and rear pedestals including the front and rear trick plates and the front and rear rows of knitting needles evenly moves in parallel, so that a relative position of the trick plates and the knitting needles does not change before and after changing the spacing, resulting in dispensing with stroke adjustment of the knitting needles.
  • the front and rear trick plates are mounted through a supporting body to a supporting shaft passing through plural intermediate frames in the width direction of the knitting machine, the intermediate frames being respectively erected and fixed on the front and rear pedestals, in a knitting-allowing manner together with the knitting needles.
  • Said means or mechanism for linearly moving is preferably comprised of threaded shaft (s) screwed on and passing through the front pedestal and the rear pedestal in the front-rear direction. More preferably, one of the threaded shafts has a right-hand thread and the other of the threaded shaft has a left-hand thread. This allows the structure to be simplified and driving to be easily performed.
  • each of the front pedestal and the rear pedestal may be fastened as fixed to a base machine pedestal by way of clamp means or clamp device(s) so that hydraulic means is used for fastening and unfastening the front pedestal and the rear pedestal.
  • clamp means or clamp device(s) so that hydraulic means is used for fastening and unfastening the front pedestal and the rear pedestal.
  • a first take-up roll and a presser roll are oppositely provided in parallel at below of the knitting area formed by the rows of knitting needles; and one of the take-up roll and the presser roll is mounted on a front intermediate frame while the other is mounted on a rear intermediate frame. Then, a spacing between the opposite rolls in conformity with the thickness of the three-dimensional warp knitted fabric being knitted is automatically adjusted when the spacing between the trick plates is changed.

  • nuts 13a1 and 13a2 are fixed in a built-in style in the front pedestal 5a while nuts 13b1 and 13b2 are provided in a built-in style in the rear pedestal 5b.
  • each of the front-part and rear-part threaded shafts 12a and 12b is screwed in the pair of nuts.
  • "14” denotes a coupling, which couples together the front-part and rear-part threaded shafts 12a and 12b as to be joined and fixed with each other.
  • two worm wheels 15 are respectively put tightly as fixed onto rear extreme ends of the joined threaded shafts 12, which are respectively arranged in the right and left sides of the knitting machine.
  • Each of the respective worm wheels 15 is engaged with a worm 16 as shown in Figures 1 and 3.
  • two worm shafts 17 respectively for the worms 16 on right and left sides of the knitting machine are coupled as fixed to a transmission shaft 18 by use of respective couplings 19, as respectively being supported by two bearings 20.
  • a sprocket 21 is mounted on an end of one of the worm shafts 17 to be connected, through a connecting chain 25, with a sprocket 24 mounted on a shaft 23 of a motor 22 that is provided on the base machine pedestal 6.
  • "26" denotes supporting metals for supporting the transmission shaft 18.
  • Figures 4 and 5 are sectional views of clamp means for fixing the front pedestal 5a and the rear pedestal 5b to the base machine pedestal 6.
  • Figure 4 shows two clamp sites in the front pedestal 5a while
  • Figure 5 shows one clamp site.
  • three pairs of clamp sites namely six clamp sites as paired by every two of them, are provided on each of the front and rear pedestals 5a and 5b, since the operational width of the knitting machine is 75 inches in the double raschel machine in this embodiment. It goes without saying that the number of the clamp sites can be increased or decreased in accordance with the increase or decrease of the operational width of the knitting machine.
  • Figure 4 is a sectional view taken along the line B-B in Figure 2. With respect to Figure 4, only the clamp means on left-hand side on the drawing will be explained at below since those on front-part and rear-part sides are equivalent in construction.
  • the flange member 31 is engaged with a concave portion on the upper surface side of the cylinder member 27.
  • the belleville spring 30 is thus held between a bottom surface of the concave portion and the flange member 31.
  • the other distal portion, i.e. a lower distal portion, of the shaft part 32 passes through a long hole 43, which is formed on the base machine pedestal 6 and which is long in the front-and-rear direction, so as to be capable of sliding therein.
  • a double nut 33 is screwed from a bottom surface 6a of the base machine pedestal 6, directly or via a washer as shown in Figure 4.
  • the front pedestal 5a and the base machine pedestal 6 are thus tightly and closely fixed with each other by the belleville spring 30.
  • There applies force of 1.8 t (metric tons) per each clamp means in the case of this embodiment, by way of parenthesis.
  • the clamp means of the rear pedestal 5b has a structure substantially same to that of the clamp means described above. Therefore, detailed description thereof is omitted here.
  • a pipe 34 provided to communicate with the inner space 27a of the cylinder member 27 of the clamp means.
  • the pipe 34 is communicated to six cylinder members 27, which are located separately, of the front pedestal 5a as shown in Figure 2.
  • the pipe 34 is further communicated through a communication pipe 44 to six cylinder members 27, which are located separately, of the rear pedestal 5b.
  • "35” denotes a "hydraulic jack” or hydraulic pump provided closely to the machine pedestal 6 and connected to an end of the pipe 34 as to pump oil into the inner space 27a of each cylinder member 27.
  • the "hydraulic jack” is arranged to use the hydraulic pressure obtained by the oil-pumping operation as to move the piston member 29 and its shaft part 32 against the extension-wise restoring force, or the resilience, of the belleville spring 30. That is to say, the hydraulic means are used for performing operations of fastening and unfastening the front pedestal 5a and the rear pedestal 5b against the base machine pedestal 6 by way of the clamp means.
  • the pipe 34 is omitted from the illustration.
  • the numeral 36 shown in Figure 1 denotes a three-dimensional warp-knitted fabric being knitted.
  • a fabric having a predetermined thickness is formed as knitted with yarn fed from a group of knitting reed 37 provided at above the knitting needles 1a and 1b.
  • the thickness of the fabric is determined in accordance with spacing between the trick plates 2a and 2b.
  • a lever 35a of the hydraulic jack 35 is first operated as to pump and inject oil into each space upside of the piston member 29 in the inner space 27a of each cylinder member 27.
  • the piston member 29 and its shaft part 32 thereby move to a direction shown by an arrow 38 in Figure 5 against the extension-wise restoring force of the belleville spring 30.
  • the gap is 0.4 mm.
  • a press-wise fixing of the front pedestal 5a and the rear pedestal 5b against the base machine pedestal 6 is thus released.
  • a driving signal is sent to the motor 22 as to rotate the both worms 16 on the transmission shaft 18, via the shaft 23, the sprocket 24, the connecting chain 25 and the sprocket 21; the worms 16 being located on right-hand and left-hand sides of the knitting machine.
  • Such rotation of the worms 16 makes the two threaded shafts 12 on right-hand and left-hand sides of the knitting machine to simultaneously rotate, by rotating the both worm wheels 15.
  • the transmission shaft 18 When to widen the spacing between the trick plates 2a and 2b, the transmission shaft 18 is rotated in the counter-clockwise direction in view from a side associated with the motor 22. This makes the front pedestal 5a to move frontward and makes the rear pedestal 5b to move rearward so that the front and rear pedestals 5a and 5b separate from each other in a linear manner. On such occasion, it goes naturally that each spacing between the intermediate frames 4a and 4b, the supporting shafts 7a and 7b, the supporting bodies 3a and 3b, the trick plates 2a and 2b and the knitting needles 1a and 1b also increases by a same distance with increase of the spacing between the front and rear pedestals 5a and 5b.
  • Plural take-up rolls are provided below the knitting area, which is formed by the rows of the knitting needles, as arranged in parallel to the width direction of the knitting machine, that is, a direction vertical to the sheet surface of Figure 1.
  • a first take-up roll 39 among the plural take-up rolls is located nearest to the knitting area and arranged to face to a presser roll 40.
  • a distance between the first take-up roll 39 and the presser roll 40 is automatically changed in conformity with thickness of the three-dimensional warp knitted fabric 36 that is being knitted; by following construction: the first take-up roll 39 and the presser roll 40, which are opposed with each other, are respectively provided in one body with the intermediate frames 4a and 4b, or with the intermediate frames 4b and 4a.
  • the first take-up roll 39 is provided in one body with the front intermediate frame 4a
  • the presser roll 40 is provided in one body with the intermediate frame 4b
  • spacing between the first take-up roll 39 and the presser roll 40 is changed by same amount with change of the spacing between the front and rear pedestals 5a and 5b.
  • a motor is used in changing the trick plate spacing. It goes without saying, however, that not only a motor but also the other driving means may be used, such that a handle may be mounted to the transmission shaft so as to be manually rotated, for example.
  • the front and rear pedestals 5a and 5b respectively supporting the front and rear trick plates 2a and 2b move toward and away linearly from each other, by the means for moving.
  • a relative stroke position of the knitting needles 1a and 1b for the trick plates would not change before and after changing the spacing. This results in dispensing with stroke adjustment of the knitting needles after changing the trick plate spacing.
  • the above-mentioned means for moving are threaded shafts 12, which run through the front pedestal 5a and the rear pedestal 5b as screwed on them, in the front-and-rear direction.
  • one of the threaded shafts 12 has a right-hand thread while the other has a left-hand thread. This simplifies a structure of the trick plate spacing changer, resulting in easy driving.
  • the hydraulic means are used for pressing and fixing the front pedestal 5a and the rear pedestal 5b to the base machine pedestal 6 and for releasing the fixing, so that a changing operation can be easily and conveniently performed.
  • the invention is particularly applicable to a double raschel machine comprising two rows, front and rear, of knitting needles, wherein the spacing of rows of the front and rear knitting needles and the spacing of the front and rear trick plates belonging to the knitting needles should be changed in changing the thickness of a fabric to be knitted.
