Definitions

  • the invention relates to a device for separating a continuously conveyed stream of shingled flat workpieces, preferably bags or sacks, with two successive endless conveyor belts, of which the second downstream conveyor belt is driven at an increased speed to pull the shingle stream apart at the rate of shed separation and after the separation of the shingled stream into a leading and a trailing part is driven again at the same speed as the first conveyor belt, and with a separating device arranged between the two conveyor belts.
  • the separating device In a device of this type known from DE-0S 28 52 603, the separating device consists of an endless conveyor which overlaps the second conveyor belt and can be driven independently of the first conveyor belt, which is arranged over a part of its circumference and takes over the scale flow from the first conveyor belt and over it has second conveyor belt holding cross bars, so that the intermittently driven at higher speed second conveyor belt pulls the shingled stream apart to create a gap.
  • the known device does not make it possible to achieve a proper separation of the scale flow in such a way that parts leading from the scale flow can be cut off with a precisely predetermined number of workpieces. In the known device, namely, it cannot be predicted with certainty at which point the scale flow is pulled apart to separate a leading scale flow part. In particular, the separation of a shingled stream is problematic in the known device if it consists of thin lobed workpieces.
  • the object of the invention is therefore to provide a device of the type specified at the outset, with which shingled stream parts leading from a shingled stream can be separated with a precisely predetermined number of workpieces. Furthermore, a device is to be created with which shingled streams can also be separated from thin lobed workpieces.
  • this object is achieved in a device of the generic type in that the separating device consists of an endless intermediate conveyor belt, which runs parallel to the starting area of the second conveyor belt, rotates at a lower speed than the second conveyor belt during the separating process and that with a device for holding at least the first workpiece of the trailing shingled stream is provided.
  • the first workpiece of the trailing shingled stream part is held on the intermediate belt conveyor and fixed thereon, so that the shingled stream can be pulled apart at a predetermined point to create a gap without the individual workpieces of the shingled stream parts even being displaced if they are made of thin lobed material.
  • the intermediate conveyor belt consists of at least two belts running parallel to one another, which are arranged between outer conveyor strands of the second conveyor belt, that the belts in Equal distances are provided with two cams that the belts are below the conveying plane of the conveyor strands of the second conveyor belt and the cams extend during the intermittent run over the upper strands of the intermediate belt conveyor during the separating process over the conveyor plane of the second conveyor belt, and that above the Belts of the second intermediate belt conveyor are arranged endless counter-pressure belts against which the cams press the front end of the trailing stream of shingles.
  • the belts of the intermediate belt conveyor can of course also enclose the individual belts of the second conveyor belt between them.
  • the two cams arranged on each belt of the intermediate belt conveyor are in the ready position of the intermediate belt conveyor in the area of the respective front and rear surface lines of the deflection rollers of the belts. They change their position during a separation process, in which they each run over the upper strands of the ligaments.
  • the endless counter-pressure belts expediently run over freely rotatable deflection rollers which are mounted at the ends of pivotably mounted, inclined links.
  • the counter pressure belts can generate the necessary pressure due to the weight of their deflection rollers and linkage.
  • the links are expediently connected to one another by coupling rods to form a four-link parallel link system.
  • pressure medium cylinders are pivotally mounted in the machine frame above the lower run of the pressure belts, the piston rods of which carry press rams at their free ends, which at the start of the cutting process can be lowered onto the overlapping area of the last workpiece of the leading part of the scale flow to be separated .
  • both the first workpiece of the subsequent shingled stream part and the last workpiece of the leading shingled stream part to be separated are clamped, so that due to the differential speeds a safe pulling apart of the shingled stream is ensured without fear of uncontrolled displacements of the workpieces.
  • a spring can be provided which holds the cylinder in its ready position at a stop.
  • the pivot bearing of the cylinders and the stops are expediently adjustable in the longitudinal direction for adjustment to different workpiece lengths.
  • the cylinder is expediently a pneumatic cylinder.
  • the distance of the extensions of the cylinders projected onto the shingled stream from the upper center lines of the rear deflection rollers of the intermediate belt conveyors can correspond approximately to a workpiece length in such a way that the rear cams, when they rotate, clamp the first workpiece of the subsequent part of the shingled stream to be separated, while the Place the ram on the last workpiece of the leading part of the shingled stream to be separated.
  • FIG. 1 only the rear side wall 1 of two side walls 1, 2 is shown, between which a feed conveyor belt 3 is mounted.
  • This feed conveyor belt 3 is adjoined by a first conveyor belt pair 4 in a level that is lower than the level of the feed belt 3, which is followed by a second conveyor belt pair 5.
  • Both the conveyor belt pair 4 and the conveyor belt pair 5 can be driven by separate motors 6 and 7, respectively.
  • An intermediate conveyor belt pair 8 overlaps, as can be seen particularly in FIG. 2, the two conveyor belt pairs 4 and 5.
  • the intermediate conveyor belt pair 8 is driven by a separate motor 9. This motor drives the shaft 10, which drives the two belts 8 'or 8 '' of the conveyor belt pair 8 loop around.
  • FIG. 1 drives the shaft 10 which drives the two belts 8 'or 8 '' of the conveyor belt pair 8 loop around.
  • the shaft 10 ' is mounted in the two side walls 1 and 2 in such a way that the two conveyor belts 8' and 8 '' run below the level of the conveyor belt pair 5.
  • the second shaft 11 carrying the conveyor belts 8 'and 8'' serves at the same time as a deflection for the conveyor belt pair 4.
  • the shaft 11 is offset, in such a way that it has a smaller diameter in the area in which it is wrapped by the conveyor belts 8 'and 8''than in the area in which it has the conveyor belts 4' and 4 '' of the conveyor belt pair 4 carries.
  • a pressure belt 15 is provided, which rests on the sheet stream 12 from above.
  • This belt loops around two rollers 16 and 17, which are connected to a cross member 19 via a parallelogram linkage 18. The latter is firmly connected to two cross members 20 and 21 which are supported on the two side walls 1 and 2.
  • a piston-cylinder unit 22 is further articulated, which is held by a spring 23 against a stop 24.
  • a stamp 25 is provided, which is preferably made of elastic material, such as rubber. The distance between the piston-cylinder unit 22 and the roller 27 can be changed in a manner not shown in such a way that the plunger 25 presses on the leading end of the sack after the piston rod 22 'has been extended and is no longer gripped by the cam 14.
  • the motor 9 of the intermediate conveyor pair 8 is switched on.
  • the cam 14 located on the left in FIG. 1 moves in a clockwise direction, presses the scale flow 12 from below and presses it against the pressure belt 15, which is then raised around the articulation points of the parallelogram linkage 18 on the cross member 19.
  • the motor 7 of the conveyor belt pair 5 is driven at a higher speed than the two synchronized motors 6 and 9, so that the scale flow part located in front of the left cam 14 is removed at high speed.
  • the ram 25 of the piston-cylinder unit 22 is lowered as the motor 7 accelerates. He presses on the leading edge of the last sack of the scale flow part that is to be conveyed away at high speed and presses this last sack onto a conveyor belt of the pair of conveyor belts 5. Later on, the piston-cylinder unit then swivels counterclockwise while simultaneously moving the piston rod 24 around its articulation point on the cross member 17.
  • FIG. 2 it can be seen that the device for pressing the scale flow shown in FIG. 1 is provided twice, namely a pressure belt 5 and a piston-cylinder unit 22 are assigned to each side of the first pair of conveyor belts and the second pair of conveyor belts.
