Definitions

  • the invention relates to a device for producing all-metal spring cushions from knitted metal pieces.
  • all-metal feather pillows have been produced as follows: on a circular knitting machine, the metal wire is knitted into a tube, which is then laid out to form a double-layer tape. This is provided with a transverse corrugation (embossing). Pieces of a given length are cut from the embossed tape and rolled up into a wrap. The end of the knitted piece is fixed to the winding by hand crocheting, and the knitted winding obtained in this way is put into a press mold by hand and pressed together in a press, the individual wires of the knitted layers coming into close frictional engagement with one another and the feather cushion having the desired final geometry .
  • FR-A-1 064 768 describes the production of such all-metal spring cushions for use in vibration dampers.
  • the present invention is intended to provide a device for producing all-metal spring cushions, which enables largely automated production without human intervention, in particular eliminating the need to manually insert the knitted fabric into the press mold.
  • the object is achieved according to the invention by a manufacturing device according to claim 1.
  • the knitted pieces are wound inside a winding tube, which also serves as an insertion aid for a compression tube.
  • the finished knitted wrap can thus be easily transferred mechanically from the winding station to the press station.
  • a device according to claim 3 is characterized by a particularly simple mechanical structure. In addition, there is no joint between the mandrel and mandrel. The press ram can easily be moved over the mandrel.
  • the development of the invention according to claim 6 also serves to fix the knitted piece end on the winding without a counterelectrode inserted into the winding by micro-welding.
  • extendable gripping means can be realized and actuated from the winding mandrel in a particularly simple manner.
  • the development of the invention according to claim 9 is advantageous with regard to the high throughput of the manufacturing device, since the winding and closing of the knitted packages and the pressing can be carried out simultaneously in different, spatially separate work stations.
  • a feed rail via which the knitted piece is fed to the winding station, can be arranged in a spatially fixed manner. It does not have to be moved out of the step table path when the step table is moved.
  • the end of the knitted piece can be positioned very precisely in the immediate vicinity of the fastening device, taking into account length fluctuations of the knitted piece.
  • the radius of the knitted roll is automatically taken into account when determining the remaining angle of rotation for the drive working on the winding mandrel.
  • 10 denotes a machine bed which bears a winding station, designated overall by 12, in which in practice, 1-2 m long knitted pieces of spring wire are used to form a knitted roll with a diameter of, for example, 4 cm and a height of, for example, 5 cm is wound and the end of the knitted piece is attached to the winding by micro-welding.
  • Winding sleeves 14, in which this winding and closing of the knitted fabric takes place in the manner described in more detail below, are fastened to arms 16 of an indexing table 18, generally designated 18, which can be moved in 90 ° steps about a horizontal axis by a drive 20.
  • the machine bed 10 also carries a pressing station, designated overall by 22, which lies opposite the winding station 12 with respect to the axis of the indexing table 18 and in which the knitted fabric rolls axially to form a spring cushion be compressed, the height of which is approximately half the initial height of the reel.
  • a winding drive 24 drives a winding mandrel, designated overall by 26. This has a flange 28 which, with play, can engage somewhat from one end in the respective winding tube 14 in the winding station, as shown in FIG. 3.
  • a front winding section 30 of the winding mandrel 26 extends essentially through the entire winding sleeve 14 and carries on its outer surface four sets of driving wires 32 which are set in the winding direction (arrow 34).
  • a feed window 36 is provided in the peripheral wall of the winding tubes 14, which are open on both sides and are butted against the associated arms 16. Its lower boundary surface 38 is slightly higher than the uppermost surface line of the winding section 30, so that the free end of a knitted piece 40 when cantilevered advancing over the boundary surface 38 above the winding section 30 gets into the path of the driving wires 32 rotating in the direction of arrow 34 and is taken along by the winding mandrel 26.
  • the upper boundary surface 42 of the feed window 36 extends tangentially to the inner surface of the winding tube 14.
  • a feed rail 44 which has a bottom wall 46 and lateral guide walls 48.
  • a transverse round guide rod 50 is provided which, together with a transverse strip 52 lying in front of it, forms an insertion funnel for the knitted piece 40 and holds the knitted piece on the bottom wall 46, so that it assumes a defined position relative to a light barrier 54, which comprises a transmitter part 56 embedded in the bottom wall 46 and a receiver part 58 arranged in alignment in the strip 52.
  • the path of the outermost surface line of the winding tube 14 is indicated by a dashed circle 60, the path of the innermost surface line by a dashed circle 62.
  • the end face of the feed rail 44 is arranged tangentially to the circle 60.
  • a welding device, generally designated 64 is provided tangentially to the circle 62, essentially opposite it. This comprises three welding electrodes 70 which can be displaced in bores 66 of a housing 68 and are each guided via an insulating sleeve 72 in the associated bore 66.
  • bores 74 of the winding tube are aligned with the bores 66, so that the ends of the welding electrodes 70 can be moved against the surface of the knitted package 76 produced in the winding tube 14, the end of the welding electrodes 70 in the bores 74 is performed similarly as in the bores 66.
  • the welding electrodes 70 are biased by springs, not shown, so that they are elastically adjusted during welding after softening the knitted material.
  • the welding electrodes 70 work together with a cylindrically curved counterelectrode 78 which is carried by an electrode shaft 80, as can be seen in particular from FIG. 3.
  • the electrode shaft 80 is provided with a flange 82 which closes the right-hand end of the winding tube 14 in a similar manner to that which the flange 28 does for the left-hand tube end.
  • the flange 82 is in the center formed with a recess 84 into which the end of the winding section 30 can engage with play.
  • the counter electrode 78 is parked under the feed window 36 over most of the winding process, as shown in FIGS. 2 and 3.
  • An electrode drive 88 which works on the electrode shaft 80, is controlled by a second light barrier 86 located in front of the light barrier 54.
  • the position of the second light barrier 86 is selected so that after the counter-electrode 78 is brought into circulation (also in the direction of the arrow 34), a full number of knitted layers are just wound over the counter-electrode 78 and the end of the knitted piece 40 is about the size of the Weld spots lies behind the center of the counter electrode 78. This really fixes the outermost end of the knitted piece 40 to the knitted roll 40, and there are no protruding ends which would impair later handling of the knitted roll, but also of the finished spring cushion. Details of the control of the electrode drive 88 will be described later with reference to FIG. 6.
  • the winding drive 24 is seated on a first carriage 90 which can be moved parallel to the axis of the indexing table 18 and which is moved by a double-acting hydraulic working cylinder 92.
  • the electrode drive 88 sits on a carriage 94 which is moved by a double-acting working cylinder 96.
  • the winding mandrel 26 and the counterelectrode 78 can thus be pulled out in the axial direction from the knitted roll produced in the winding tube 14 in the winding station 12, and then this winding tube 14 can be moved through the indexing table 18 are first moved into a 90 ° intermediate position and then into a 180 ° pressing position.
  • the inner surface of the winding tube can be provided with closely adjacent semicircular sliding ribs 98, as shown in FIG. 1.
  • the winding drive 24 can be connected to a mains line 104 via a controllable switch 102 in order to set the winding mandrel 26 in the direction of the arrow 34.
  • the switch 102 is controlled from the "1" output of a bistable multivibrator 106 whose set output "S" is connected to the output of the first light barrier 54.
  • all components that can be triggered by edges are to be components that respond to rising signal edges.
  • the output signal of the second light barrier 86 is sent to the set input of a further bistable multivibrator 108, the "1" output of which is connected to the control terminal of a further switch 110.
  • the electrode drive 88 can be connected to the power line 104 via the latter.
  • the winding drive 24 and the electrode drive 88 are stopped simultaneously by resetting the two bistable flip-flops 106 and 108 as a function of the falling signal edge of the light barrier 54 by a specially designed digital residual angle control circuit 112.
  • the residual angle control circuit 112 is connected to a resolver 114, which cooperates with the winding drive 24 and in each case emits a pulse for a predetermined angular increment, the output signal of which is transmitted to an auxiliary counter 118 via an AND gate 116.
  • a small distance in front of the light barrier 54 is another light barrier 120, the output signal of which is connected via an inverter 122 to the set terminal of a bistable multivibrator 124. Its "1" output drives the second terminal of the AND gate 116. At the same time the flip-flop 124 is set, the auxiliary counter 118 is also reset to zero.
  • the flip-flop 124 is supplied with the output signal of the light barrier 54 via an inverter 126.
  • the level obtained in the auxiliary counter 118 thus corresponds to the number of angular increments of the winding drive 24 that were required to move the end of the knitted fabric from the light barrier 120 to the light barrier 54. This number depends on the respective radius of the knitted fabric 76. From this number it can now be calculated with better accuracy by how many angular steps the winding drive 24 has to be moved further so that the end of the knitted piece 40 comes to lie directly in front of the welding electrodes 70.
  • This conversion takes place digitally in such a way that a correction memory 128 is controlled with the output signal of the auxiliary counter 118, in which the corresponding angle values were previously stored.
  • the applicable residual angle value is entered as an increment number on the presetting terminals PR Given counter 130.
  • the correction memory 128 and the counter 130 are activated via delay elements 132, 134 from the "0" output of the flip-flop 124.
  • the output signal of the delay element 134 simultaneously turns on an AND gate 136, via which the output pulses of the resolver 114 are passed to a down-counter terminal of the counter 130.
  • the output signal at the sign terminal S of the counter 130 can then be used via an inverter 138 to reset the bistable multivibrators 106 and 108.
  • the end of the knitted fabric now lies just before the welding electrodes 70.
  • the "0" output signal of the bistable multivibrator 106 simultaneously triggers a monostable multivibrator 142 via a delay circuit 140, the period of which is somewhat longer than the time required for the end of the workpiece to be welded to the package.
  • the latter controls a switch 144, via which a second supply terminal of the winding drive 24 can be connected to the power line 104, when the winding drive 24 is acted upon in the arrow 34 in the opposite direction. In this direction of rotation, the driving wires 32 work out of the knitted package 76.
  • the period of the flip-flop 142 corresponds to the time required to pull the winding mandrel 26 out of the knitted fabric.
  • the output signal of the monostable multivibrator 142 is provided on a line 146 in order to bring about a simultaneous axial pulling out of the winding mandrel 26 and counterelectrode 78 from the knitted winding 76 by appropriate pressurization of the working cylinders 92, 96.
  • the Pressing station 22 has a winding tube 14 each with a pressure tube 148 in such a way that the inner surfaces of both tubes pass flush into one another.
  • the press sleeve 148 is fixedly connected to the machine bed 10 by a holder 150. Its bottom is formed by a slide 152 which runs in guide grooves 154 fixed to the frame.
  • a press mandrel 156 is guided through the slide 152 and is connected to the piston rod 158 of a double-acting working cylinder 160.
  • a press die 162 can be moved through the winding sleeve 14 into the press sleeve 148 and thereby pushes the knitted roll 76 into the press sleeve 148 and onto the press mandrel 156.
  • the press punch 162 has a central bore 164 into which the press mandrel 156 can run.
  • the press cylinder 166 is then relieved and the press mandrel 156 is pulled out of the finished spring cushion by the working cylinder 160, which is indicated by dashed lines in FIG. 7 at 168.
  • the mandrel 156 is retracted as far as behind the slide 152, so that the latter can then be moved away in the direction perpendicular to the plane of FIG. 7 by a double-acting working cylinder 170 (see FIG. 1).
  • the finished spring cushion is then ejected from the press sleeve 148 and arrives at a delivery chute 172.
  • the press die 162 is moved back into the starting position shown in FIG. 7, as is the slide 152 and the press mandrel 156. Thereafter, a further winding tube 14 with a further knitted package 76 can be moved into the pressing station 22.
  • the winding tube 14 is now made of electrically insulating material, e.g. made of a ceramic material and connected directly to the compression sleeve 148 by means of bolts 174.
  • the winding mandrel 26 has a shaft section 176 which is rotatably guided through the press ram 162, and the pressing mandrel 156 is formed directly on the winding mandrel 26.
  • the bore 164 has a larger diameter rear bore section 178, which can accommodate the resilient driving wires 32 with play, while a bore section 180 which fits the pressing surface and fits to the press mandrel 156 has only a short axial dimension.
  • a rotary drive for the winding mandrel 26 is located behind the press ram 162 and is again mounted on a slide similar to that shown in FIG. 1.
  • the combined winding / pressing station according to FIG. 8 operates in the same way as described above.
  • the end of the knitted piece is welded in place by the welding device 64 to be considered above the drawing plane without a separate counter electrode.
  • the lower layers of the knitted fabric in connection with the winding mandrel 26 serve as counterelectrode. Since the winding sleeve 14 is electrically non-conductive, a defined current away from the welding electrodes in the radial direction is also obtained in this way.
  • the press ram 162 is simply moved against the slide 152 in the device according to FIG. If the knitted package is sufficiently compacted, the winding drive is moved to the left in FIG. 8, as a result of which the pressing mandrel 156 is pulled out of the slide 152 and the finished spring cushion. Thereafter, the slide 152 is moved away and the spring cushion is pushed out by pushing the plunger 162 further.
  • the driving wires 32 can also be made essentially retractable into the surface of the winding mandrel 26, as shown in FIG. 9.
  • the drive wires 32 are carried tangentially running away from an actuating shaft 182 and penetrate openings or slots 184 in the now hollow winding mandrel 26, which enable tilting.
  • the actuating shaft 182 is connected to the winding drive and takes the winding mandrel 26 with it via a lost motion connection 186 acting in the angular direction.
  • the driving wires 32 are automatically extended, and are automatically drawn in when the actuating shaft 182 is rotated in the opposite direction.
  • the friction between the knitted winding 76 and the winding tube 14 or the inertia of the winding mandrel 26 is sufficient for changing the lost motion connection. If not, the driven part of the lost motion connection can be braked by an additional brake 188, which can be a magnetic brake that is only energized when switching.
  • the microweldings can also be produced by microflames, which are directed through the bores 74 against the end of the knitted fabric 76. These microflames can either be flames generated by gas combustion or arcs maintained between two electrodes.
