Definitions

  • the invention relates to a weaving machine with devices for receiving and Guiding active and passive shaft rods according to the characteristics of the The preamble of claim 1.
  • the shaft rods not required for weaving shed formation i.e. the passively operating shaft rods, pivoted out of the drive area of the heald frames and either in one on the bell crank of the relevant shaft rod existing clamping means can be mechanically locked or on an outside of the Movement range of the heald frames arranged so-called magnetic strip are held, see also DE 195 48 848 C1.
  • the known holding devices also have the disadvantage that in the course of Shaft change does not preposition the previously passive shaft rods in this way are held that when the heald frames are inserted into the weaving machine Coupling means on the shaft side not without manual intervention with the relevant shaft-side coupling means is connectable.
  • the object of the invention is therefore to overcome the disadvantages of the prior art avoid and devices for receiving and guiding both the passive and also create the active pairs of shaft rods in which, in the event of a Change the respective shaft rod pairs with their shaft rod side Coupling means are held in a defined position around the Coupling process with the shaft-side coupling means without manual To be able to perform the intervention.
  • both the active and the passive shaft rod pairs are guided or held together in lateral longitudinal guide elements arranged outside the range of movement of the shaft rods.
  • a certain number of longitudinal guide elements together form a first and a second guide and holding device, which are each arranged on a support plate mounted on sub-connectors of the weaving machine.
  • each longitudinal guide element has an arcuate longitudinal guide which can be of any geometric cross-sectional shape, but is preferably a simple geometric shape in which a guide element connected to the respective shaft rod is movably guided or held. It is irrelevant whether the stem rods are active stem pairs or passively active stem pairs. It is crucial that the pairs of shaft rods are held in the guides in a substantially vertical position even when there is no connection to the heald frames. In particular in the case of weaving machines, whose heald frames can be automatically connected to the respective shaft pair, manual pairing of the shaft pairs or their coupling means on the coupling means of the respective heald frame is eliminated. Another advantage is that machine vibrations can no longer exert any influence on the mounting of the passively active pairs of shaft rods. It is also advantageous that the operator of the weaving machine does not have to operate in an area of the weaving machine that is difficult to access when changing articles to lock or unlock the shaft rods.
  • Figure 1 shows the left side cheek 1 of a weaving machine with the sub-connectors 2, which connect the left side cheek 1 with the right side cheek, not shown.
  • a support plate 3 is fastened on the sub-connectors 2 near the two side cheeks.
  • Each carrier plate 3 receives a plurality of longitudinal guide elements 4. The entirety of the longitudinal guide elements forms, together with the carrier plate 3, the first device 5 for receiving and guiding the active and passive shaft rods 6.
  • the second device 5 is not shown here.
  • Suitable connecting means connect each longitudinal guide element 4 to the carrier plate 3.
  • Each longitudinal guide element 4 has a longitudinal guide 4a, which describes an arc. The size of the circular arc is determined from the movement sequence characteristics of an actively operating shaft rod 6 with the guide element 7.
  • a large number of deflection levers 8 are arranged on a common shaft (not shown) pivotable about its central axis 9.
  • the shaft rod 6 is articulated at the free end of the lever arm 8 a of the first bell crank 8.
  • a connecting rod 10 is articulated in the joint 10a.
  • the connecting rod 10 transmits the movement control of the shaft 11 via the pairs of shaft rods 6 and via the coupling rod-side and shaft-side coupling means 12, 13, as shown in FIG. 2 and FIG.
  • FIG. 2 shows a suitable connection means 14 for connecting the carrier plate 3 to the sub-connector 2.
  • the individual longitudinal guide elements 4 are also connected to the carrier plate 3 in the end regions of their longitudinal extent by suitable connecting means 15.
  • the connecting means 15 are also only indicated here.
  • the shaft rod 6 is, as is known, formed in two parts, namely from a part 6a carrying the coupling means 12 and from a part 6b articulated on the lever arm 8a of the bell crank 8.
  • the part 6a is inserted into the part 6b and locked in place by screws 16.
  • the leg 7a of the guide element 7 is inserted here in the part 6b and clamped in the part 6b by means of the screws 16, for example via clamping bodies 17, 18.
  • the parts 6b of the shaft rods 6 are known to be located parallel to one another and connected to the relevant lever 8.
  • the shaft rod part 6a is inserted between a first clamping body 17 and a second clamping body 18 in the shaft rod part 6b.
  • the leg 7a of the guide element 7 is inserted between the first inner narrow side of the part 6b formed as a rectangular hollow profile and the first clamping body 17.
  • the parts 6a, 7a, 17 and 18 inserted into the hollow profile are clamped in part 6b by means of the screws 16 screwed into the wall of the second narrow side of the hollow profile.
  • Each longitudinal guide element 4 has a recess 4a which is open on one side and into which the guide lug 7b of the guide element 7 projects.
  • the longitudinal guide 4a and the guide lug 7b can have a freely selectable geometric shape. It is crucial that between the contour of the guide lug 7b and the surfaces 4b, 4c of the longitudinal guide 4a running in the form of a circular arc, there is a sufficiently large amount of play not to impair the guiding of the actively operating shaft rods 6 and the holding of the passively active shaft rods 6.
  • the first and second lever 8 is articulated on the connecting rod 10 in the articulation points 10a, 10b.
  • the lever 8 on the left side of the side cheek 1 is connected to the dobby, not shown, by means not shown here.
  • the two shaft rods 6 form a pair of shaft rods.
  • Each shaft rod 6 carries a shaft-side coupling means 12 which is connected to the respective shaft-side coupling means 13 on the heald frame 11.
  • a guide and holding device 5 for the entirety of the shaft rods 6 is arranged on the sub-connector 2 on the right and left of the respective side cheek 1.
  • the device 5 arranged on the right side of the side cheek 1 consists of a plurality of longitudinal guide elements 4 with a concave longitudinal guide 4a into which the guide element 7 engages with the guide lug 7b of the shaft rod 6, while the device 5 arranged on the left side of the side cheek 1 consists of a plurality of longitudinal guide elements 4 with a convex longitudinal guide 4a.
