Definitions

  • the invention relates to a braking device for braking and depositing on a stack of areally extending, spaced supplied workpieces, such as in particular blanks of cardboard or the like made of flexible materials.
  • the invention has the object to provide a braking device of the type in question available that gently slows down mechanically supplied easily supplied workpieces, and beyond that in a simple manner to a variety of workpieces can be adapted.
  • a braking device for braking and depositing areally extending, spaced supplied workpieces, in particular of cardboard, according to claim 1 by the measures that the workpieces are fed to a brake drum whose peripheral speed is smaller than the feed rate of Workpieces, and that in the feed direction end of the workpiece at least one cam presses a brake roller passing workpiece against the brake roller and reduces the speed of the workpiece.
  • the braking device according to the invention has a number of advantages.
  • it is best suited for cardboard or other, non-self-supporting workpieces, for example, from films in which it would come to a deformation on emergence on a stop. Such is excluded by the end-fitting of the workpiece between the cam and the brake roller.
  • a not self-supporting, easily deforming workpiece such as a cardboard or the like retains a largely stretched position or the workpiece receives the time to take before laying on a stack again a stretched position.
  • the cam protrudes a roller.
  • This structurally simple solution makes it possible to adapt the speed components of roller and brake roller to each other by simply setting a drive.
  • the circumferential speed of the roller will then be set in such a way that the cam covers a revolution in time corresponding to the feed of a workpiece.
  • constant spacing of the supplied workpieces can thus be ensured in a simple manner that the cam engages only at the end of the workpiece to press the workpiece against the brake roller and thus decelerate.
  • the preferably rounded, the workpiece pressing against the brake roller pressing surface of the cam and the surface of the brake roller can run on each other in the nature of the surfaces of a pair of rollers, with a speed difference in the regularly
  • roller is arranged above the brake roller and that the axes of the roller and the brake roller lie in a common plane transverse to the feed direction.
  • the cam can be fixed axially displaceable on the roller so that, for example, printed cardboard can be detected and braked outside the actual pressure range.
  • the printed image of such a cardboard remains securely undisturbed.
  • Punches be taken as a carry handle.
  • the angular velocity of the roller carrying the cam is adjustable.
  • the time interval can be predetermined, in which the open gap remains between the brake roller and the roller, so that a workpiece can enter this gap undisturbed. Only at the end of the workpiece is the cam end of the workpiece pressing it down against the brake roller. By this measure, various lengths of the workpieces are taken into account.
  • a sensor system may further be provided which measures the length and / or distances of workpieces in the feed direction and in which a controller sets the angular velocity such that the cams press each workpiece against the brake drum ,
  • a controller sets the angular velocity such that the cams press each workpiece against the brake drum .
  • workpieces after passing through the braking device according to the invention are scaly, but spaced superimposed on a magazine, a pallet or the like fed in a dropping motion.
  • the roller follows in the feed direction at least one guide band which rotates above the workpiece. An emigration of the workpieces upwards due to bending as a result of the free entry into the gap and the end-side pressing down to the brake roller is thus reliably prevented. Rather, the scaly superimposed workpieces are moved away from the guide belt and stored on, for example, a pallet or in a magazine in the falling motion.
  • the rotational speed of the guide belt of the feed speed of the workpieces approximately equal, in particular is the same, so that the workpieces with entry into the gap between the roller and the brake drum experience no speed reduction, if, for example.
  • Bends bending the guide band invest.
  • a drive shaft of a drive and one of the guide band are connected via a belt, which eliminates the need for an independent drive of the guide band. It is particularly thought that the drive of the guide belt via a belt drive together with the drive of the workpieces of the braking device supplying conveyor devices such as conveyor belts or the like.
  • the above-described braking device will be arranged at the end. After stacking the workpieces, a transfer to a packet inverter can take place, which then turns the stack on a conveyor belt or another conveyor. For an increase in capacity can also be provided that two brake devices according to the invention a switch is connected upstream. It is preferred that the braking devices following the turnout are arranged offset in height and that a transfer device transfers the stacked by the braking devices packages to a packet inverter. A space-saving design of a high-capacity production line is thus made possible.
  • FIG. 1 is an isometric view of a brake device according to the invention
  • 2 is a side view
  • 3 a plan view
  • Fig. 5 the use of the braking device further explained.
  • FIG. 1 shows, in an isometric view, a braking device 1 according to the invention for braking and depositing areally extending, in particular equally spaced, supplied workpieces 4, preferably cardboard boxes, for example, printed, punched and singulated at high speed in a production line 2 (not shown) for example, 500 m / min and with high clock frequency of about 10 pieces / sec. the braking device 1 are supplied.
  • the workpieces 4 are supplied to a linkage 5 of a conveyor belt 6 a brake roller 7 in the feed direction 8 according to the arrow.
  • a further roller 11 is arranged, wherein the axis 12 of the brake roller 7 in a plane transverse to the feed direction 8 with the axis 13 of the roller
  • the roller 11 projects two cams 14, 15, which, as shown in FIG. 4, press a workpiece 4 passing through the brake roller 7 downwards against the brake roller 7 and thus reduce the speed of the workpiece 4.
  • the angular velocity of the shaft 11 is adjusted so that the cams 14,15 the workpiece 4 always press against the end of the brake roller 7, in which one revolution of the cam 14, 15 takes as long as a workpiece 4, taking into account the distance of the workpieces 4 with each other is supplied.
  • the cams 14,15 or possibly the complete roller 11 can be replaced operationally and / or the cams can be adjustable transversely to the feed direction 8, so that an adaptation to different workpieces 4 is easily possible. If the workpiece 4 is, for example, a sheet printed on the upper side, then the cams 14, 15 are set in such a way that such a workpiece 4 on unprinted surfaces ends with the brake roller 7 passing from the cams 14, 15 against the brake roller 7 can be pressed. Damage to the upper-side print image of the workpiece 4 is then excluded. Correspondingly, geometries of the workpieces 4 can also be taken into account, for example punched-out sections.
  • an adaptation of the preferably rounded contact surface 16 by a suitable material selection of the cams 14, 15, a coating or surface structuring on the workpieces 4 can be carried out for a gentle pressing against the brake roller 7.
  • the angular velocity of the roller 11 is adjustable, so that the interval at which the cams 14,15 impinge on the brake roller 7 while enclosing a workpiece 4 is adjustable.
  • Angular velocity of the shaft 11 is such that the cams 14,15 each workpiece 4 press exact end in time with the feed against the brake roller 7 down.
  • FIG 3 also shows that the cams 14,15 and the guide belt 17 are set to gap, here the centrally located guide belt 17 is bordered by the cams 14,15 as it were.
  • the rotational speed of the guide belt 17 corresponds substantially, preferably exactly the feed rate of the workpieces 4 in the feed direction 8 in front of the braking device 1.
  • no reduction in speed of the workpiece 4 if this is done with the free entry into the Gap between the brake roller 7 and the roller 11 and the braking bends and rests on the front edge side of the guide belt 17.
  • a drive of the guide belt 17 can be done in a simple manner via a belt 18 which is driven by an electric motor drive 19 of the feeders of the workpieces 4 as the conveyor belt 6 with.
  • the brake roller 7 and the roller 11 each have their own drives 20,21, so that the peripheral speeds of the two rollers 7,11 in a simple manner independently of each other, can be set for themselves.
  • FIG. 5 shows on the right a transport device 23, for example two transport belts enclosing a workpiece, at the end of a production line, not further shown, for workpieces extending in a planar manner.
  • the braking devices 25,26 put the workpieces braked as a stack 27,28.
  • This stacking of the workpieces is staggered in time, so that each one of the stack 27,28, which is completed, can be transferred via transport devices 29,30 to a height-adjustable transfer device 31.
  • This is, provided with a height-adjustable conveyor device 32, shown in Fig. 5 in two positions, Stapel.33 in a packet inverter 34, which records after turning taken stack this example, on a transport device 35 for removal.
