Definitions

  • the invention relates to a device for stopping folded products transported by means of a tape guide with a stop preferably penetrated by the tape guide and a pre-adjustable braking device, preferably at least in the form of a brush that can be raised and lowered with respect to the transport plane of the tape guide and spans a table.
  • the braking device is permanently set depending on the speed of the tape guide.
  • the disadvantage here is that the mass of the folded products hitting the stop remains practically neglected.
  • the same folded products also behave completely differently, depending on which and with how much color they are printed, etc.
  • These disturbances have not been taken into account either.
  • the brake elements are subject to unavoidable wear, which can be noticed as a further disturbance variable. So far, it has therefore been necessary to take these variable quantities into account empirically and to readjust the braking device from time to time by hand. However, this required a high level of monitoring and adjustment.
  • the described state of the art therefore proves to be not user-friendly and product-friendly enough.
  • the stop can be scanned by means of a sensing device which detects the forces acting on it upon impact of the folded products or a parameter dependent thereon and that the braking device can be adjusted as a function of the value at the output of the sensing device.
  • a resilient stop that can be deflected by the impacting folding products can be provided.
  • the feeler device can simply be designed as a position sensor. This results in a mechanical measurement recording, which ensures a high level of robustness.
  • the stop can be designed as a spring, preferably in the form of a sheet clamped on one side in the region of a table-parallel edge, or it can be supported by at least one spring.
  • the touch device only requires a push pin that rests against the stop and can be moved by this. The measures mentioned thus result in a particularly simple and robust design, which is also advantageously suitable for retrofitting.
  • a folding device provided with a sword folding mechanism generally enables the production of products which, in addition to a first longitudinal folding and a transverse folding, also have a second longitudinal folding which is produced with the aid of the sword folding mechanism.
  • This consists of an up and down movable folding knife 1, which cooperates with folding rollers, not shown here.
  • the folding knife 1 is received on a swivel arm 2 which can be driven by means of a drive shaft 3.
  • the folding knife 1 runs parallel to the bands of a band guide 4, which feeds the once longitudinally and transversely folded products to a stop 5 arranged downstream of the folding knife 1. At this stop 5, the products come to a standstill before the third fold is carried out.
  • the stop 5 consists of a sheet metal which is received on a crossbar 7 which overlaps the table 6 receiving the band guide 4 and which is provided with recesses 8 for the bands of the band guide 4 deflected downstream of the stop 5.
  • the table 6 is of course interrupted in the area of the folding knife 1, so that the folding products can be pushed into the folding gap between the folding rollers arranged below the table 6 by means of the folding knife 1.
  • the stop 5 is a braking device for braking the folded products before they hit the stop 5 upstream.
  • this braking device contains a brush 9 arranged overlapping the table 6, the bristles of which brush against the folded products received between the upper and lower belts 4.
  • the brush 9, like the table 6, is divided in the area of the folding knife 1 in such a way that there is a gap for the folding knife 1.
  • the brush 9 is arranged to raise and lower the braking force.
  • the brush 9 or each brush part is received by brackets 10 on a carriage 11 which is displaceably mounted in height.
  • the guide 12 receiving the slide 11 is fastened to the cross member 7.
  • the slide 11 is in threaded engagement with at least one set screw 13 running perpendicular to the table plane.
  • the setscrew 13 is supported on both sides in the axial direction on a bracket 14 of the crossmember 7 which overlaps the guide 12 and is provided at its upper end with a drive wheel 15 that engages with a means of a cone Sole 14 recorded drive motor 16 is drivable drive wheel 17.
  • the cross member 7 carrying the stop 5 and the brush 9 can be arranged fixed to the frame.
  • the cross member 7 is attached to a swivel arm 18 which is clamped onto a support rod 19.
  • a set screw 20 supported on a bracket 21 fixed to the frame, engages, by means of which the swivel arm 18 can be adjusted by hand when the clamp connection is released.
  • the desired basic position of the stop 5 and the brush 9 is hereby set.
  • the brush 9 is then tracked during operation by activating the motor 16.
  • the drive shaft 3 is rotated accordingly.
  • the drive shaft 3 is provided with a helical toothed pinion 22a, which is in engagement with a likewise helically toothed wheel 22b, which is adjustable in the axial direction and can be driven for this purpose by means of an adjusting device 23 designed as a gear.
  • the activation of the motor 16 for raising and lowering the brush 9 and / or the activation of the actuating device 23 for advancing and resetting the folding knife 1 take place in such a way that the folding products running onto the stop 5 are not damaged and do not rebound.
  • the elastic deflection of the sheet 5 forming the stop 5 and clamped in the region of its upper edge when each product strikes is detected by means of a feeler 24 and introduced into a control circuit for regulating the braking force exerted on the folded products.
  • a position sensor is provided with a feeler pin 25, which rests against the back of the stop 5 and can be displaced by the elastic deflection of the sheet forming the stop 5.
  • the output of the pushbutton device 24 is at one input of a controller 26.
  • a controller 26 At the other input of the controller 26 there is a setpoint generator 27.
  • This is provided with an adjusting button 28 which enables the desired braking effect to be preset.
  • the motor 16 and / or the actuating device 23 With the help of the controller 26, the motor 16 and / or the actuating device 23 are controlled.
  • the signal lines are indicated in the drawing by dashed lines.
  • the control loop outlined above ensures that the braking device or devices are tracked during operation in such a way that the impact energy released at the stop 5 remains within the scope of the setpoint value which can be predetermined by the setpoint generator 27.
  • the stop 5, which can be scanned by means of a stylus 25, is in the area of a Edge clamped sheet metal is formed, which is deflected in the manner of a leaf spring when each folded product to be stopped hits.
  • the stop 5 can be engaged behind in the area of its attachment by a spring arrangement 29, which results in a particularly large overall deflection when using a deflectable plate.
