Definitions

  • the invention relates to a knitting machine with several Laying rails connected to drives via coupling points, their laying needles towards a work line are directed.
  • a knitting machine with several laying rails which too are called laying bars, is constructed in such a way that the laying rails are arranged in a fan shape in cross section are.
  • the laying needles therefore go from the imaginary working line out in the form of radial rays to the outside, being the space available for the laying needles stands, due to the other elements of the knitting machine, such as knitting needles, pile boards, tee boards etc., limited is.
  • every lay rail becomes an angular segment allocated.
  • the angular range of such Angular segment is relatively small. It is only a few degrees, usually about 8 to 15 degrees.
  • the laying rails are driven lengthways, to cause an offset movement of the laying needles. This means that you have acceleration forces for the Movement of the guide rails must initiate so that they in Direction of the longitudinal axis of the guide rails are. As a result, connecting elements between the laying rails and their drives parallel to each other and run close to each other have to.
  • the invention has for its object a direct To be able to control laying rails.
  • This task is the beginning of a knitting machine mentioned type in that the drives side by side arranged in adjacent angular segments are from the work line and in one a smaller area adjacent to the working line Width than in an area away from the working line exhibit.
  • So drives are used for the laying rails fit into each of the angle segments. This is it is possible to move all drives in the axial direction, i.e. movement direction the laying rails, in the same position to arrange.
  • the drive conditions for the machines are equal to each other. Is solved constructively this is because the drives are not above their height more with a constant width (perpendicular to the direction of movement the laying rails), but with a width that decreases towards the working line.
  • the "working line” is an imaginary line, in which the laying needles would intersect if they are extended. It is not absolutely necessary that the extensions of all laying needles cut in the working line. Minor deviations are allowed.
  • Each drive preferably has a motor that further away from the working line than the coupling point is arranged.
  • the coupling point can then be relative be placed close to the working line so that the Laying rails at a convenient location with driving forces can be applied.
  • the engine that im The principle that forms the largest component of the drive is on installed a larger radius in the angular segment. Thereby it is possible to close the individual drives to form the working line with a smaller width than further away from the work line.
  • the coupling point is preferably at a first Element arranged opposite a second Element on which the engine is fixed, relocatable is, between the first and the second element at least two parallel guides are formed.
  • the two guides ensure that the first element its alignment with the second element, i.e. to the Engine maintains, even if over the Coupling point forces act on the first element which are not in line with those caused by the engine Driving forces lie.
  • At least one guide is closer located on the work line as the engine.
  • the first element preferably has a second one Attachment point on at least one guide. This provides additional support for the first element, so that tilting or tilting avoided will, even if greater forces are exerted on the laying rails be transmitted.
  • the second attachment point arranged between two bearings of the command center is. So that the guide is on both sides of the attachment point supported so that the first element even with larger forces with the required orientation is held on the drive.
  • the two guides are preferably together twice connected. This is also a measure to Keep guides parallel and thus the first element in the desired orientation to the motor on the one hand and on the other hand to hold the laying rail.
  • One of the guides preferably has a ball screw on. Via a ball screw a rotary motion of the engine in simple and relative transferred to the first element with low loss. If you place this ball screw in a guide, then you save space, so that the drive on does not need to become excessively wide at this point.
  • the motor is preferably coaxial with the ball screw arranged. So you don't need an additional one Gearbox more between the motor and the ball screw, but can drive the motor directly onto the ball screw let it work.
  • the motor has a rotating Tension element with a displacement of the first element Gearbox is connected.
  • a tension element can formed by a chain, a toothed belt or the like his.
  • the engine can be relative Arrange far away from the work line. The engine can therefore have a certain size without the drives interfere with each other in the arrangement.
  • the drive preferably has a section which tapers towards the work line.
  • this section can for example by using a housing section sloping walls.
  • Such training facilitates assembly. You can namely the side walls of the tapered sections parallel to each other align and so the drives on simple Assemble way.
  • a knitting machine not shown, has several Lay rails 1-3 on, in the direction of a double arrow 4 are moved back and forth to thread through Laying needles 5 have been guided in a predetermined manner around other active elements, for example knitting needles, around set.
  • This work line 6 is a virtual line. It is at the intersection the extensions of the laying needles 5 of the laying rails 1-3.
  • the laying rails 1-3 have suspensions 7 with which they are attached in the knitting machine. Every shot is via a plunger 8 with a drive 9 connected, which generates the axially directed force with the laying rails 1-3 in the direction of the double arrow 4 be moved back and forth.
  • Each angular segment has only a limited angular width A, usually 8 to 15 °.
  • the Space for the laying rails 1-3 in total at about 120 ° limited.
  • the drives have a special shape. You are in an area which is adjacent to the working line 6, with a smaller one Width (in the circumferential direction) than in one greater distance. Each drive has this to do at least one section 10 that extends to the work line 6 tapered. This section 10 must do not go over the entire height of the drive 9. A further section 11 can certainly remain in which the walls of the drive 9 parallel to each other are aligned.
  • the plunger 8 engages via a coupling point is formed by a ball pin 12 on the drive.
  • the ball pin 12 is in a first element 13 of the drive 9 (Fig. 3) used, the opposite one second element 14 is displaceable. To move a motor 15 used.
  • the engine 15 is located on the opposite side in relation to work line 6 End of drive 9, i.e. where am most space is available. You wear the Fact that motor 15 is basically the largest Individual component of the drive 9 is.
  • the first element 13 has a first in a linear bearing 16 mounted guide 17, which a mother 18th a ball screw 19 carries.
  • the ball screw 19 is with an output shaft 20 of the motor 15 connected.
  • the first element 13 is opposite the second element 14 to the left or right (based on the representation of FIG. 3) and depending on the direction of rotation of the motor 15th
  • the first element 13 has a second guide 21, which is designed as a guide shaft.
  • the leadership 21 is supported in two linear bearings 22, 23 in the direction of movement of the first element 13 a certain Distance from each other.
  • the first element is 13 in that distance or space between the two Bearings 22, 23 with a second fastening point 24 connected to the second guide 21. This will make one very stable guidance of the first element 13 opposite achieved the second element 14 even if the forces on the first element 13 in the vertical direction (based on the representation of Fig. 3: of have a certain distance.
  • the first Element 13 is also sufficient in relation to occurring moments stable.
  • Figures 5 and 6 show a modified embodiment. The same elements as in Figures 3 and 4 are provided with the same reference numerals.
  • the first element 13 to which the ball pin 12 is attached is, in turn, via two guides 17, 21 in second element 14 slidably mounted.
  • the motor 15 is not coaxial with the guide 17 arranged. Rather, the engine 15 is located above the second element 14. It has an output pinion 25 with a toothed belt 26 with a drive pinion 27 is engaged.
  • the drive sprocket 27 is fixed in a rotationally fixed manner on a shaft 28, the two guides via a gear 29 17, 21 drives.
  • the gear 29 has an output element 30 on that the two guides 17, 21 with each other combines.
  • the gear 29 can here also by a ball screw be educated with an associated mother.
  • the individual drives 9 in the width direction a small distance from each other.
  • the drives 9 are independent of each other on a side wall, not shown Knitting machine mounted.
  • the walls in the tapered Sections 10 facilitate the opposite side Orientation.
  • the drives 9 for all laying rails 1-3 can be the same be formed. This increases the ease of maintenance. The stock of spare parts is reduced. This can save costs. Thereby, that the individual drives 9 can also be replaced individually maintainability is improved.
