Definitions

  • the invention relates to a method and a device for cutting a strip of paper, cardboard or the like. helically wound tube in individual container sleeves with a label wound by a winding belt, in which the drive speed of the cutting unit is compared with the conveying speed of the label strip and a correction of the cut is made in the event of a deviation.
  • a method for spiral labeling is known.
  • this problem is solved in such a way that with a comparison of the drive speed of the cutting unit with the the size of the label strip resulting from the drive of the cutting unit is corrected.
  • a disadvantage of this method is that the correction of the cutting tool can only be carried out with great expenditure on equipment on motors, couplings, hydraulic, pneumatic and electronic adjusting devices. It follows from this that the correction device reacts too sluggishly in the event of uncontrolled changes in slope or in the case of fluctuations in the paper thickness, so that a large reject of cut container sleeves cannot be avoided.
  • the object of the invention is to avoid these disadvantages of the known prior art and to provide a simple solution to the problem of a helically wound tube made of strips of paper, cardboard or the like. to cut at precisely specified points. In particular, a correction of the drive of the cutting unit should be avoided.
  • the variable resulting from the comparison of the drive speed of the cutting unit with the conveying speed of the label strip is used to control the speed of the winding belt.
  • the drive of the cutting unit is no longer corrected, but rather, based on a speed deviation between two directly proportional sizes of the system, influences the drive of the winding belt by this an additional rotary movement is preferably entered, which makes the winding belt and thereby the sleeve slower, for which purpose the winding belt speed is always set to be a small percentage greater than the cutting unit speed.
  • the purpose of this is that the winding belt speed only has to be reduced in order to achieve a correction. In principle, however, it would also be possible to increase the winding belt speed for correction when the method according to the invention is carried out.
  • the comparison variable is advantageously determined by photoelectric scanning of control marks attached to the label at specific intervals.
  • the driving force for correcting the speed of the winding belt is taken from the drive of the cutting unit via an electromagnetic clutch controlled by the comparison variable, in particular the photocell.
  • the method according to the invention determines on the basis of the speed comparison whether the label strip is correct in relation to the setting of the subsequent cutting process or whether a correction must be made. If a deviation in the speed is found, the speed of the winding belt and thus the pipe speed is influenced. The correction takes place immediately upon detection of a deviation, since only a coupling process has to be triggered.
  • the device according to the invention for carrying out the spiral labeling method is characterized by a deflection drum for the label strip in its path of movement in front of the tube, an infinitely adjustable gear for both the winding belt and the cutting mechanism, a drive arranged on the deflection drum with the drive speed of the cutting ⁇ factory rotating photoelectric scanning device for the control marks on the label strip and an electromagnetic clutch arranged between the drive of the cutting unit and the winding belt and controlled by the photoelectric scanning device, which additional rotation in the drive of the winding belt to accelerate or accelerate it slowdown.
  • the deflecting drum preferably has a circumference which corresponds to one or half a cutting mechanism stroke.
  • the basic setting of the spiral labeling machine it is advantageous to provide a further geared motor that can be coupled to the drive of the winding belt.
  • the basic setting can be carried out very quickly and correctly in particular if an indication of the possible difference between the drive speed of the cutting unit and the conveying speed of the
  • the device for spiral labeling has an electric motor 1, which drives a gear 2, which can be continuously adjusted in order to set the overall machine speed.
  • a winding belt 4 is connected and driven to the output shaft 3 of the transmission 2 and, on the other hand, a cutting mechanism 6 via an infinitely adjustable PIV transmission 5.
  • the power is converted here by means of a cam plate 7 and a crank mechanism 8 which is on the carriage of the cutting unit 6, not shown, acts.
  • the function of the winding device described is to wind up strips of paper or cardboard (not shown) by means of the winding belt 4 to form a helically wound tube 9.
  • a label strip 10 is applied to the outside of the tube 9 in the direction of movement behind the tube 9 shaped in this way, which is shown schematically in the drawing.
  • the label strip 10 then represents the outermost layer on the tube 9, which has a specific pitch angle corresponding to the strips which form the tube 9.
  • the supply of the label strip 10 to the tube 9 in the direction of movement behind the winding belt 4 is via a deflection drum 11, which has a circumference that corresponds to a whole or half a knife slide stroke of the cutting unit 6.
  • the label strip 10 is guided around the deflection drum 11 by almost 360 °.
  • a photo cell 12 is arranged on a toothed disc 13, which has approximately the same diameter as the deflection drum 11, the position of the photo cell 12 being such that the markings 14 arranged on the label strip 10 are scanned can.
  • the toothed disk 13 is driven together with the drive shaft 15 of the cam disk 7 of the cutting unit 6 and rotates at the speed thereof which corresponds to that of the knife carriage.
  • the shaft 15 also continues to the other side of the cam plate 7. Via an electromagnetic clutch 16, the drive of the cutting unit 6 is connected to the drive of the winding belt 4, in the differential gear 17 of which an additional movement can be entered when the electromagnetic clutch 16 is engaged.
  • a gear motor 18 is also connected to the differential gear 17, which runs to the right or left and which can be used to intervene in the differential when the machine is reset.
  • This intervention takes place at the push of a button and helps to bring the printed image of the labeled tube 9 into line with the knife set of the cutting unit 6.
  • the automatic synchronization correction with the photocell would under certain circumstances take too long when the machine was readjusted, since when starting the cutting unit 6 could be ahead of the pipe 9, which would entail a large number of incorrectly cut off container sleeves.
  • the drive of the winding belt 4 can only be slowed down, since in spiral labeling by adjusting the PIV gear 5 the procedure is such that the belt speed is always a small percentage greater than the cutting unit speed.
  • the labeling machine shown has a tachometer 20 for the speed of the deflection drum 11 and a tachometer 21 for the speed of the toothed disk 13 and thus the cam disk 7, the difference between which is displayed on a device 22 for optical control.
  • This allows manual intervention in the PIV transmission 5 to adjust the cutting mechanism speed, which is shown schematically in the drawing.
  • the PIV gear 5 is basically used to adapt the cutting unit speed to the winding belt speed, which changes with the different diameters and pitches.
  • the PIV transmission 5 is therefore set more often by hand, and these inputs
  • the position of the synchronization is facilitated in that the display device 22 displays the cutting device speed and pipe speed or deflection drum speed as a difference.
  • Spiral labeling on the PIV transmission 5 is carried out in such a way that the belt speed and thus the pipe speed is always a small percentage greater than the cutting unit speed. This makes it possible to subsequently only have to reduce the belt speed in order to achieve synchronism (correction). This correction is made automatically:
  • the label strip 10 runs over the deflection drum 11, next to which the photocell 12 rotates at the speed of the cutting mechanism - cam disc 7.
  • the photocell 12 scans the length of the tube section of the markings 14 made on the label strip 10. If the photocell 12 does not rotate at the same speed as the marking 14 on the label strip 10, it sends an impulse via an amplifier to the electromagnetic clutch 16, which couples the differential gear 17 to the shaft 7 and inputs an additional rotary movement into the differential gear 17 . As a result, the speed of the winding belt 4 is slowed down.
  • the entire path of the label strip 10 via the deflection drum 11 is available to the photocell 12 for correction.
  • the correction is therefore made immediately after a deviation occurs, so that the
  • Cutting unit 6 always cuts the tube 9 at the precisely specified points.
