Definitions

  • the invention relates to a transport and braking mechanism in a labeling device of the type specified in the preamble of claim 1.
  • a label tape carrying self-adhesive labels is gradually pulled over a dispensing edge with the release of a self-adhesive label and stopped in the intermediate phases.
  • DE-PS 24 32 501 In a known transport and braking mechanism of this type (DE-PS 24 32 501) is in the feed direction behind the dispensing edge a permanently fixed drive roller mounted on the frame and a counter-pressure roller which can be pressed against the drive roller with intermediate clamping of the empty return part of the label tape and one in the feed direction before Drive roller arranged, provided from a frame-fixed stopper and a counterpressure against which it can be pressed against it with intermediate clamps of the label tape.
  • a lever fixed to the frame which has a first lever arm carrying the counterpressure roller and a second lever arm carrying the counterpressure stopper and which can be pivoted back and forth between two end positions via a pneumatically triggerable actuating mechanism such that in one end position the counterpressure roller when lifted off Counter pressure stopper is pressed against the drive roller and in the other end position the counter pressure stopper is pressed against the stopper when the counter pressure roller is lifted off.
  • the tape brake with stopper and counter pressure stopper is arranged in the feed direction in front of the dispensing edge, so it acts on the self-adhesive label cut the leading part of the label tape.
  • both the drive roller and the counter pressure roller are partially wrapped around by the return part of the label tape, so that even when the counter pressure roller is lifted off, a pulling force by the sliding drive roller on the label tape is exercised.
  • this leads to a more or less severe abrasion on the label tape and on the surface of the drive roller when it is at a standstill, so that there is a risk of tape overstretching or even a tape break on the one hand and premature wear of the roll surface on the other.
  • the invention has for its object to improve the known transport and braking mechanism of the type mentioned in such a way that the wear in the area of the drive roller is reduced and the risk of belt overstretching or even a belt breakage is avoided even during longer downtimes.
  • the invention is based on the idea that an arrangement of the stopper in the feed direction behind the dispensing edge in the vicinity of the drive roller Looping of the drive roller and the counter-pressure roller is unnecessary, so that the label tape can be lifted from the drive roller in the stopped state and thereby abrasion on the label tape and the drive roller can be avoided.
  • the stopper is arranged in the feed direction behind the dispensing edge near the drive roller, and that the label tape can be pressed tangentially and without wrap against the drive roller and lifted from it in the stopped state.
  • a tightening of the label tape in the area of the dispensing edge can be achieved in that the supply roll of the label tape has an adjustable bearing friction and / or that in the area in front of the dispensing edge a brush or similar braking element rests against the tape advance.
  • a further improvement in this regard can be achieved in that the tape brake has a second counterpressure stop arranged on a third lever arm, which can be pressed against a second stopper fixed to the frame in the advancing direction before the dispensing edge when the counterpressure roller is lifted off by interposing the feed part of the label tape.
  • the leading part of the label tape located in front of the dispensing edge and equipped with the self-adhesive labels is passed through the area between the stopper and the counterpressure stopper, so that it be in the stopped state together with that behind the dispensing edge sensitive return part of the label tape is clamped between the stopper and counter pressure stopper.
  • the transport and braking mechanism shown in the figures in various exemplary embodiments is intended for a labeling device in which the leading part 8 'of a label tape equipped with self-adhesive labels 15 is pulled off a supply roll (not shown) in the direction of the arrows 20 and is released via a dispensing edge, not shown, with the release of the Self-adhesive labels 15 is performed.
  • the empty return part 8 "of the label tape in the feed direction first passes through a tape brake consisting of a stopper 2 fixed to the frame and a counterpressure stopper 3 and then past the drive roller, which is continuously driven at constant speed in the direction of arrow 22, to a drive roller not shown
  • the speed of the drive roller 1 is set via a controllable electric motor or via a regulating gear.
  • the transport of the label tape 8 ', 8 "in the direction of the arrows 20 is carried out by the drive roller 1 in that the return 8" is pressed by a counter-pressure roller 11 against the peripheral surface of the drive roller 1.
  • the counterpressure roller is mounted on a first lever arm 5 'of a rocker arm pivotable about the axis 10 fixed to the frame, on the second lever arm 5 "of which the counterpressure stopper 3 is arranged.
  • the actuation of the lever 5', 5" takes place with the aid of a pneumatically or electromechanically actuatable actuating mechanism 4 which is connected via a control rod 7 and one at one end at its hinge 9 to the control rod 7 and at the other end rigidly to the two-armed lever 5 ', 5 "
  • Control lever 6 can be pivoted back and forth between two end positions. In one end position the counter pressure roller 11 is pressed against the drive roller with the counter pressure stop 3 lifted off, with intermediate clamps of the return 8 ′′ (FIG.
  • FIG. 3 shows a constructive embodiment of the transport and braking mechanism shown in the functional diagram in FIGS. 1 and 2.
  • an additional band brake is arranged in the region of the band advance 8 ′, which has a stop 12 fixed to the frame and a third lever arm 14 rigidly connected to the lever 5 ′, 5 ′′ arranged counter pressure stop 13.
  • the tape feed 8 ' is passed between the stop 12 and the counter pressure stop 13.
  • both counter pressure stops 3 and 13 are lifted off the label tape 8 ", 8' while in the braking position the counter pressure stops 3 and 13 when the counter-pressure roller 11 is lifted, they are pressed together against the respective stoppers 2 and 12.
  • a brake layer 18 on the stopper and counter-pressure stop made of resilient material, such as rubber, ensures reliable and uniform braking of the two band parts 8 ', 8 ".
  • the leading part 8 'of the label tape is also passed through the tape brake 2, 3.
  • the deflection rollers 16 and 17 ensure that the feed part 8 'and the return part 8 "of the label tape are aligned essentially parallel to one another in the area between the stopper 2 and the counterpressure stopper 3.
  • both tape parts 8' are thus and 8 "held together.
  • the embodiment according to FIG. 6 largely corresponds to that according to FIG. 5, in which the forward part 8 'and the return part 8 "are passed together through a single band brake consisting of stopper 2 and counterpressure stopper 3. It is merely modified in that the deflection roller 17 is omitted and thus the forward part 8 'and the return part 8 "of the label tape are oriented essentially parallel to one another at a small distance from one another over the entire distance between the deflection roller 16, band brake 2, 3 and dispensing edge 24.
  • the dispensing edge 24 is arranged at the free end of a thin-walled table 26, which is simultaneously designed as an abutment for a printing or embossing unit, not shown, which acts on the self-adhesive labels from above.
  • the label tape is pulled over the dispensing edge 24 under deflection by 180 ° in such a way that the self-adhesive labels 15 detach from the tape due to their inherent rigidity.
