Definitions

  • the invention relates to an eccentric machine driven by a weaving machine with shafts which are driven by means of a handlebar and a roller lever with scanning rollers which bear against an eccentric driven for rotation, a pivotable release lever being provided which is connected to the roller lever in a rotationally fixed manner and which Control of the scanning roller on the eccentric.
  • Eccentric machines of this type on weaving machines are known. They are primarily used for the production of simple weaves such as Twill fabrics used.
  • the invention is therefore based on the object of designing an eccentric machine of the type mentioned at the outset in such a way that even in the event of longer downtimes, positions in the tissue are not shown or occur.
  • the problem is solved by the characterizing part of claim 1.
  • a drive element On the release lever assigned to the eccentric machine and known per se, a drive element is thus arranged which, when the eccentric machine is at a standstill, shifts the release lever so that all the shafts reach the central position.
  • the release lever present in an eccentric machine which was previously used for manually adjusting the shafts to a central compartment position, is connected to a controlled drive element, preferably to the piston rod of the drive element.
  • the drive element Via a control system that is operatively connected to the drive element, the drive element is now automatically pressurized when the weaving machine is switched off, so that the release lever brings the shafts into the central compartment position under the action of the drive element. This avoids standing spots in the fabric, because all shafts are moved to the middle shed position immediately after the loom stops and the warp threads are thus relieved.
  • the drive member is also controlled so that the binding-correct shaft position is restored shortly before the weaving machine starts, so that no weakening of the binding occurs in the fabric when the weaving machine starts up.
  • a control which first determines the starting position of the release lever before the machine is switched off, that the drive element controls accordingly in order to move the release lever into a central position and shortly before the weaving machine starts again Release lever adjusted so that it is turned back to the position it was in before the loom was turned off.
  • the drive element can take a variety of forms. It can be designed as a hydraulic or pneumatic cylinder or as an electromagnet. An electric motor drive can also be considered. It is only important that the release lever is pivoted into the previously described positions by the control and the drive element (not shown).
  • a weaving machine 24 is shown, the shafts 1 of which are driven by an eccentric machine 25.
  • the shafts 1 are driven via two parallel bumpers 2, each bumper attaching at one end to the free pivotable end of a bell crank 3, 5.
  • the second bell crank 3 is connected to the first bell crank 5 via a connecting rod 4.
  • One end of a drive rod 6 attaches to the first deflection lever 5, the other end of which is connected via a tab 13 to a roller lever 8 which carries two scanning rollers 11, each of which scanning roller is in engagement with an eccentric 9, each eccentric an axis 10 is driven to rotate.
  • a roller lever 8 which carries two scanning rollers 11, each of which scanning roller is in engagement with an eccentric 9, each eccentric an axis 10 is driven to rotate.
  • only the front eccentric 9 is shown in the drawing.
  • the tab 13 is designed to be displaceable and lockable in the longitudinal direction of the roller lever 8 in order to be able to set different strokes.
  • a further setting is made in that the drive rod 6 engages in a bore 7 in the first bell crank 5 and a further bore 26 is provided for adjusting the stroke. It is also known to design the drive rod 6 to be adjustable in length.
  • a release lever 14 is rotatably connected to an axis 15.
  • the axis 15 in turn is connected to the roller lever 8.
  • a handle 16 is arranged, with which the release lever 14 is pivoted in the arrow directions 17, 18 by hand.
  • a drive element is now arranged on the free, pivotable end of the release lever 14, which in the exemplary embodiment shown consists of a pneumatically driven cylinder 20, which is mounted on one side in a machine-fixed bearing 21 and whose piston rod 19 is adjustably connected to the release lever 14 is.
  • the release lever 14 By disengaging the cylinder 20 from a control, not shown, the release lever 14 can thus be pivoted in the direction of the arrows 17, 18.
  • the weaving machine has chair walls 22 and a main gear 23 is arranged parallel to each chair wall.
  • a control not shown, detects the pivot position of the release lever 14 at the time the loom is switched off. During the weaving process, the release lever 14 always has the same pivot position.
  • the roller lever 8 has an extension, which is referred to as a drive rocker 12.
  • a tab 13 is slidably and fixably attached to the drive rocker 12. Different shaft strokes can thus be set.
  • a device according to the present invention is only used in eccentric machines and because of the low manufacturing costs, it is a very simple way to avoid such harmful locations in the tissue.
  • the measures according to the invention ensure that the shafts located in the high shed are also brought into the middle shed position shortly after the weaving machine is switched off and all warp threads are subject to the same, normal warp tension when the weaving machine is at a standstill.
  • the binding-correct shaft position must be restored so that no weaving errors occur in the fabric when the weaving machine starts up.
  • the arrangement according to the invention also provides this.
