Definitions

  • the present invention relates to a shedding device for weaving machines, whose warp threads run in strands between an upper compartment position and one Sub-position can be moved back and forth, with electronic sample reading, the piston or a pair of pistons of each strand under the action of a signal pressure of the pressure medium alternately in the direction of the upper compartment position and sub-position of the strand in question, each strand formed as a piston rod emerging from the piston-cylinder system or each strand is connected to the piston via piston rod-like means, and having its free end in guide holes in one of the system block (10) spaced strand or piston rod guide block.
  • US-A-3 853 150, EP-A-0 536 899 and the DE-A-28 32 515 which already show a shedding device in the each strand attacks a pneumatic or hydraulic piston-cylinder system
  • US-A-5 390 709 shows a shedding device of the aforementioned Art.
  • the object of the present invention is therefore to simplify the design Building as well as creating a way to clean the Arrangement within the company, so downtimes due to malfunctions practically eliminated.
  • the cylinders are in one block encapsulated cylinder tubes or parallel bores in a ceramic block or the like; that the guide holes have a common feed line and valve means in fluid communication with a source of the pressure medium stand to periodically enable compressed air cleaning of the strand guide; and further that with the compressed air source via supply line and valve means the cylinders on the top of the pistons are in fluid communication to generate a restoring force.
  • the piston-cylinder system includes effective pistons at the free end of each strand, which are each movable back and forth in a cylinder, the pistons each sit firmly on the free end of the strand or with the latter over a piston rod are interconnected.
  • the cylinders can be connected via feed lines be connected to a pressure medium source, preferably for compressed air, which Compressed air acts on the pistons to generate a restoring force on them to bring the strands in question into the sub-compartment position.
  • the cylinders can each have control lines on the underside and via a multi-valve control or the like with the compressed air source in Flow connections are available to select the pistons and thus the strands with the warp threads in the upper compartment position.
  • the pattern control can be done via a control unit with a central computer system, which the valve means and the multi-valve control according to the entered sample data controls, the sample data created on a computer system and transferred to the control unit using diskettes.
  • the shedding device for weaving machines according to FIG. 1 is a so-called Open compartment jacquard machine, in which two sinkers 1, 2 over one common roller train 3 are connected at the lower end, the boards depending on the control here via the magnetic means 4 with two constantly counter-rotating Moving lifting knives 5.6 can be coupled, so that the attached to the roller train 3 Strand 7 and thus the relevant warp thread 8 a controlled lifting movement between an upper compartment position (left side Fig. 1) and a lower compartment position (right side) is issued.
  • Essential to the invention is now the known mechanical retraction device, consisting of one that matches the number of strands of the weaving machine Large number of tension springs to be replaced by a piston-cylinder system 10.
  • This piston-cylinder system 10 comprises effective at the free end of each strand Pistons 11, which are each movable back and forth in a cylinder 12.
  • the pistons 11 can sit firmly on the free end of the strand or with the latter be interconnected via a piston rod.
  • the cylinders 12 can in one block cast cylinder tubes with an inner diameter for example from 2.8 to 3.5 mm or parallel holes in a ceramic block his. The selection of material and construction is not subject to any restrictions.
  • the cylinders 12 are shown on the top side via feed lines 13 to one Unspecified pressure medium source, preferably connected for compressed air, which compressed air, for example with a pressure of up to 4 bar Piston 11 acts on this to a restoring force of, for example, up to to produce 250 gr to secure the strands in question in the sub-compartment position bring to.
  • the lifting force to overcome the pressure from the compressed air Piston 11 exerted retraction force is then about 280 to 560 gr and will easily applied by the board control.
  • leak sensors (not shown) be provided for monitoring and pressure adjustment or the supplied The pressure medium can always be at the same pressure level.
  • Such a previously described retraction device on a shedding device allows any working frequency of the machine, is practically trouble-free and wear-free and quiet and can easily be used on all types of Retrofit specialist training facilities.
  • the strands can also have additional piston rod-like Means be connected to the piston.
  • the guide bores 14 are via a common feed line 14 'and Valve means 15 with a source 16 for the pressure medium, usually compressed air, in flow connection to periodically perform compressed air cleaning of the strand guide to enable.
  • a source 16 for the pressure medium usually compressed air
  • the cylinders 12 are located on the underside of each of the control lines 18 and a multi-valve control 19 or fluid control or one Flow controller or the like in flow communication with the compressed air source 16 selected the piston 11 and thus the strands 7 with the warp threads 8 with, for example Press 4 to 8 bar pressure into the upper compartment position.
  • a negative pressure could alternately also occur via the control lines 18 are generated to generate the restoring force.
  • the pattern is controlled by a control unit 20 with a central computer system, which the valve means 15, 17 and the multi-valve control 19 via corresponding Signal lines 21 according to the entered sample data controls.
  • control in the above sense can of course also via the control line 13 in the opposite sense. It is also quite possible and in the context of the invention, the control via a double-piston system to effect alternately.
  • the sample data can be created, for example, on a computer system 22 and transferred to the control device 20 by means of diskettes 23.
  • the complete pattern can also be part of a Networking of several machines from a central computer to the control are transmitted, whereupon the control unit 20 of each machine Sample data from the main memory processed.
