Definitions

  • the present invention relates to a system for packaging lamellar parts, in particular stamped parts, wherein individually conveyed parts are stacked in a magazine to form a package.
  • the actual packaging device is generally connected directly to a punch press, the punched parts being continuously fed to the packaging device and stacked there.
  • the punched-out parts in the punch press are immediately pushed back into the step-by-step band from which they were punched out and are fed with this band to the packaging device, where they are ejected from the band into the magazine.
  • the punched-out parts can also be transported exposed from the punching tool to the packaging device by means of a mechanical transport device.
  • the aim of the present invention is, with little effort on additional equipment parts and space, a unun To allow interrupted production and supply of parts and to have enough time to replace magazines.
  • the solution according to the invention consists in that the magazine is preceded by an intermediate magazine, in which stacking takes place during a magazine change.
  • a stacking plunger is preferably provided, the stroke of which for stacking can be changed either into the magazine or into the intermediate magazine.
  • Figure 1 shows an overview of the entire system. It consists of a punch press 1 and a stacking device 2. These parts of the system are directly coupled and synchronized.
  • a band 3 is conveyed step by step through the punch press 1 and the stacking device 2, three rotor sheets for an electric motor being punched out in the punch tool 4, for example, and immediately pressed back into the punching opening in the band.
  • the tape 3 with the parts adhering therein gradually passes through a guide 5 into the stacking device 2, in which three punched parts 7 on a common carrier 6, three punched parts are simultaneously pressed out of the tape 3 and stacked in a magazine 8 located underneath.
  • the carrier 6 is fastened to a link 9 which is guided in vertically displaceable manner in guide jaws 10 (FIG. 4).
  • the link 9 is driven via toggle levers 11, of which the upper is articulated to an upper yoke 12 of a C-shaped gear frame 13.
  • the gear frame 13 is fixedly connected to a plunger 14, which is arranged so as to be vertically displaceable in the machine frame.
  • the tappet 14 is caused to reciprocate vertically by an eccentric or connecting rod gear.
  • the eccentric or connecting rod drive is driven synchronously with the punch press 1 by means of a chain j5, so that the two system parts always work with the same cadence.
  • the link 9, the support 6 and the plunger 7 are also made to reciprocate vertically in order to stack previously punched sheets into the magazines 8.
  • These magazines are located on a step-by-step rotary table 16, the shaft 17 of which is rotatably mounted in the lower part of the machine. At the stacking point, the turntable 16 is supported by a support 18 when it deforms under the axial forces that occur during the stacking process.
  • FIG. 2 shows further details of the transmission of the stacking device.
  • the middle joint 11a between the toggle levers 11, is connected to the levers 19 with a further toggle lever joint which is transverse to the toggle joint 11.
  • the other end of the toggle joint 19 is articulated on the vertical arm of the drive frame 13.
  • Tension springs 20 and 21 act on the joint 11a, which tend to bend the toggle lever 11 to the right in FIG. 2.
  • a roller 22 on the intermediate joint 19a of the toggle lever 19 rests on a release pin 23 which is vertically adjustable and can be fixed in the upper part of the link 9 by means of a screw 24.
  • a shock absorber 25 is arranged in the gear frame 13, on which the roller 22 strikes when the toggle levers 19 bend upward.
  • the roller 22 also strikes a sensor 26 which serves as a control sensor for the presence of this roller or the position of the toggle lever system.
  • a sensor 26 which serves as a control sensor for the presence of this roller or the position of the toggle lever system.
  • an L-shaped support 27 for a return cylinder 28 is also connected to the plunger 14.
  • This reset cylinder 28 carries on its piston rod a reset plunger 29, which serves to reset the toggle lever system into the working position shown in FIG. 1 in a manner described later.
  • the drive frame 13 is stiffened at the front by tension members 30.
  • Figure 3 shows a section through a stacking point with the magazine 8.
  • a stepped bore 31 there is a correspondingly stepped plunger 32 with a continuous channel 33.
  • a spring-loaded brake block 34 acts on the lower, tapered part of the plunger 32 and determines the axial force under which this plunger is displaceable in the bore 31.
  • Above the plunger 32 there is a stack of rotor plates 35 in the upper, further part of the bore 31, which have been pushed into the magazine from the band 3 running over the magazine in the guide 5 by means of the plunger 7 and thereby the magazine plunger 32 step by step. of the sheet thickness have shifted downwards until this plunger is in contact with the shoulder of the bore 31, as shown in FIG. 3.
  • FIG. 6 shows how these holding cams 41 engage somewhat in the clear width of the passage of the intermediate magazine at opposite points and with their shoulders 42 the free passage of the stamped parts and, if appropriate, the plunger 7, provided that this has practically the same cross section as the stamped parts.
  • FIGS. 4 and 5 correspond to Figures 2 and 3, respectively, and corresponding parts are identified in each case identically.
  • the indexing of the turntable 16 is released by the sensor 26 and this indexing can take place.
  • further monitoring sensors can be provided which scan the position of the holding cams 41 of the intermediate magazine 38 and also only release the advance when these supporting cams are in the inner position shown, which means that there are no metal sheets in this area and there is no pestle.
  • the turntable is advanced, for example, within approximately one second, and during this time the sheets are stacked in the intermediate magazine 38. With the cadence of the machine given above, this would be about 10 sheets, for example.
  • the toggle lever system is returned to the extended position according to FIG. 2 by means of the hydraulic or pneumatic cylinder 28 and its plunger 29 acting on the roller 22. which extends the stroke of the ram downwards.
  • each tappet together with a new sheet that has been ejected from the band 3, will eject the sheet stack from the intermediate magazine 38 into the main magazine 8 underneath.
  • the further sheets are then pushed directly into the magazine 8 again, as initially described, to form a stack 35.
  • the turntable 16 is part of an implement (not shown) with several stations.
  • an axis can be inserted into the stack 35, the lower end of this axis being able to enter the continuous channel 33 of the magazine plunger.
  • an insulating washer can be placed on the front of the stack, a collector and a bearing on the axle.
  • the entire magazine plunger 32 is then raised either with the stack 35 or the stack 35 connected with further parts, so that the stack 35 emerges from the magazine upwards. It is then gripped by pliers and removed.
  • the magazine plunger 32 remains in its upper end position and returns to the stacking position in the same, as shown in FIG. 5. During the stacking process, the plunger 32 is then gradually pushed down until it reaches the lower end position again
  • the drive could possibly take place via a hydraulic or pneumatic cylinder, which can be brought into two specific end positions, which end positions also determine the working positions of the link 9 or the punch 7. In this case too, this cylinder could be switched over when the Ku. lisse 9 or the stamp 7 remain with respect to the drive member. A corresponding switchover could also be carried out using purely electrical means.
  • the entire stroke of the drive device could also be changeable, i.e. this stroke could be reduced if the stacking in the intermediate magazine is to take place during the advance. While it was assumed above that the stacking takes place at three points at the same time by means of three stacking stamps 7 in three magazines, more or fewer magazines and stamps could of course be provided.
