Definitions

  • the invention relates to a magnet system for a selection block in textile machines, especially bistable magnet system for needle selection, wherein a magnetic is used to select the needle assigned to the magnet system actuatable, rotatably mounted elongated control flap is provided, which is designed as an anchor of the respective magnet system, and which end of the control flap facing the magnet system with permanent magnetic Means is provided, and a selection block with such Magnet systems.
  • Knitting machines circular knitting and flat knitting machines
  • magnetic systems are provided for the selection of the needles, which are generally in so-called selection blocks are summarized.
  • a specific knitting pattern to knit must be certain at a time Knitting needles can be selected and other needles just Not.
  • the control of the selection means is modern Knitting machines made electronically, one speaks then from electronic needle selection.
  • the desired pattern is in an electronic memory filed and is when knitting the textile part read out, and the needles are over the interface of the selection block selected accordingly.
  • the selection block there are energy converters that convert electrical control signal into a mechanical one Change in position of those required for needle selection Control flaps that protrude from the selection block.
  • the selection blocks are generally of a number provided by control flaps, each control flap one Selection level served.
  • Each control flap is with one Control curve provided with needle or circuit board feet cooperates.
  • the control flap can have two positions take, namely the "basic position" non-selection and select the "working position".
  • the board feet run in the 'Non-select' position past the control flaps and are not touched. If a control flap is moved to the 'select' position, the assigned board foot runs on the control curve and is towards the knitting cylinder or needle bed pressed. Due to the change in position of the board mechanically the prerequisite is created that lifting (Select) the corresponding needle from the 'Do not knit' position to 'Knit' position or 'Catch' is accomplished.
  • control flaps in the Both positions are preferably small electric magnets used in the selection block.
  • Such a selection block is from EP-0 219 029-B1 known.
  • the known system is made up of a large number of small magnets, individual parts and Assemblies built that an assembly of the selection block design complex and cost-intensive.
  • FR-A-1 564 603 and also FR-A-2 093 555 is a magnet system known for a selection block in textile machines for needle selection, being magnetic for the selection of the needles assigned to the magnet system actuatable control flaps are provided, the armature in one piece are trained. It is also known from FR-A-1 564 603 that To design the magnet system bistable, the one facing the magnet system End of the control flaps or the armature with permanent magnetic Means is to be provided.
  • the invention is therefore based on the object of a magnet system of the type mentioned at the beginning that reduces the drive power required and thus the volume can be reduced. In doing so also a simple and inexpensive installation as well as a Reduction of the pitch distance in the case of adjacent ones Magnet systems can be achieved.
  • the magnet system one with an excitation winding provided, elongated magnetic core, which forms a control flap magnet region on the end face that the control flap is essentially in the axial direction of the magnetic core axis extends that that provided with the permanent magnetic means End of the control flap is arranged in front of the end face of the magnetic core, that a single permanent magnet is provided as the permanent magnetic means is, the direction of polarization parallel to the end face or transverse runs to the magnetic core axis, and that on both sides of the magnetic core and the control flap magnet area a pole piece is provided, which before the end of the magnetic core and the permanent magnet area the control flap extends and is connected in a magnetically conductive manner or is in one piece with the bottom of a half-shell housing, so that for the Return flow of the control flow is a closed soft magnetic return over the soft magnetic housing shell to the other, rear Side of the magnetic core is present.
  • the magnet system according to the invention also less wear and thus increased wear Lifespan.
  • Selection block 1 shown for a textile machine.
  • the selection block essentially consists of one cuboid housing in which several magnet systems are arranged, each control flap 2 for control of the needles of the textile machine.
  • control flaps protrude in the illustration of FIG. 1A on the left side of the selection block.
  • On the selection block is on the opposite side provided a connector 3 through which the electrical Signals for actuation / control of the individual Magnet systems are performed.
  • control flaps can each be in two different Positions are moved, in the illustration at the lower control flap the second possible position is indicated by dashed lines.
  • the front edge of the control flap covers a distance of approx. 2 mm.
  • the adjacent control flaps 2 are at a pitch distance P arranged of about 5 mm, mentioned here should be that even smaller distances easily possible are.
  • the selection block 1 consists essentially of two Half shells 4, 5, used in the magnet systems 6 are.
  • 2 is a section through the selection block 3
  • FIG. 3 shows a view the one half-shell 4 with the magnet systems used.
  • For better visibility of details 4 is a half-shell in perspective Shown view in which only one of the magnet systems is inserted.
  • the magnet systems 6 essentially consist of one with an iron core 7 provided bobbin 8 on the an excitation winding 9 is wound.
  • the magnet systems are form-fitting in corresponding recesses in the Half-shell inserted, with the lower end of the core magnetically conductive with the half-shell made of magnetic conductive material is connected.
  • In the front The area of the magnet system are lateral pole pieces 11 formed in the half-shell, which also serves as a stop serve for the movement of the control flap 2.
  • the control valve which is shown in FIGS. 5 A, B enlarged is rotatably supported on an axis 12, and her the end face 13 of the iron core 7 of the Magnetic system end is with a permanent magnet 14 provided.
  • the control flap 2 shown in FIGS. 5 A, B is manufactured as a stamped and bent part made of steel. She is with a cranked storage area 16 for receiving the Axis 12 and an angled area 17 on which the Control surfaces 15 are formed. The opposite The area of the control flap is overmouldable Contour with undercut 18 and hole 19 provided, onto which a plastic part 20 is injection molded. The plastic part is provided with a recess in which a permanent magnet is inserted and attached.
  • 6 A, B is a modified control valve 2 ' shown.
  • the plastic part 20 ' With the recess for receiving of the permanent magnet, as well as the bearing area 16 ' includes.
  • a Steel part 22 used (molded) that with the control surfaces 15 for controlling the needles of the knitting machine is provided.
  • the coil body 7 is a sectional view of the coil body 8 shown with the iron core 7 of the magnet system.
  • the coil body is made of plastic material injected and with molded locking tabs 23 and centering 24 provided when inserting the bobbin / of the magnet system in the recesses of the Snap the half-shell behind the corresponding locking shoulders and keep the magnet system positioned in the half shell.
  • the magnet systems are in a mutual in the half shells Distance of 2 P used. Then there are the magnet systems of a half shell around the pitch distance P offset to the magnet systems of the others Half-shell provided so that when the the two half shells the control flaps the total Have pitch pitch P. With this arrangement it is possible, the magnetic systems of a half shell for themselves ultimately considered at twice the distance Pitch distance P to be provided, thereby volume advantages arise for every magnet system.
