  • the sleeve labels are typically shrunk by heating and thus secured against slipping.
  • first label tube is further removed from a buffer memory, while the end portion is glued to an initial portion of the second label tube. Subsequently, the two label tubes are glued together further promoted until the second label tube has reached the cutting unit and thus the separation and labeling can be continued.
  • DE 10 2007 056348 A1 discloses a device in which the end of a label tube is separated at the lateral longitudinal folds and another label tube is placed between the resulting tabs and glued with double-sided adhesive tape.

Since the pressing of the adhesive dispenser can already be accomplished by a simple pivoting mechanism, the mechanical effort for this is particularly low. Furthermore, for the attachment of the adhesive elements, a conveying movement of the label tube can be exploited so as to enable the transfer roller or a carrier with the adhesive elements in motion and so set a conveyor mechanism in Klebspender in motion. Overall, the automatic attachment of the adhesive elements thus simplifies the connection of the two label tubes and is less time-consuming. For example, so the buffer memory can be configured smaller in the labeling and thus cheaper.

  • the gluing station 1 is intended to glue the end portion 5a of the first label tube 5 to the initial portion 6c of the second label tube 6. This will be explained in more detail below with reference to FIGS. 2A-2D or 3A-3D.
  • the gluing station 1 comprises a support frame 20 on which the table 22 is fixedly arranged. About the table 22 slides the folded first label tube 5 along the stop 24a, as long as the end portion 5a is not reached. Furthermore, another stop 24b is arranged on the table 22, with which the initial section 6c of the likewise folded, second label tube 6 can be aligned parallel to the first label tube 5.

They can each be moved together and apart in the directions Ri and R 2 via the adjusting device 32a and 32b and thus pressed against the first label tube 5 from both sides at the same time. Thereby, the adhesive members 7a, 7b are attached from below and above to the end portion 5a of the label tube 5. Thus, the label tube 5 is accessible from both sides for the opposite adhesive dispenser 31 a, 31 b, located in the table 22, a longitudinal slot 25 which extends across the width of the label tube 5.
  • the adjusting devices 32a, 32b are each designed as a parallelogram mechanism, in which at least one of the legs is pivoted by an electric motor or the like. Through the parallelogram are the adhesive dispenser 31 a, 31 b are moved together and efficiently perpendicular to the folded label tube 5.
  • the adhesive dispensers 31a, 31b are formed with the transfer rollers 33a and 33b, respectively; alternatively, however, donation edges are also conceivable.
  • the transfer rollers 33a, 33b rotated and thereby the pre-cut adhesive elements 7a, 7b unwound from the supply rolls 34a, 34b, isolated and attached to the end portion 5a.
  • the transfer rollers 33a, 33b are connected via a gear to the supply reel 34a, 34b, so that the wound-up and pre-cut adhesive elements 7a, 7b can be better unrolled.
  • the transfer rollers 33a, 33b are mounted without further gear elements and the band-like contiguous adhesive elements 7a, 7b are unrolled solely by the tensile force.
  • the adhesive elements 7a, 7b may be applied to carrier tapes, which remain in the adhesive dispensers 31a, 31b.
  • the adhesive elements 7a, 7b can be detached with donor edges of the carrier bands by abrupt deflection.
  • FIGS. 1A-1C that the adjusting devices 32a, 32b are arranged on the moving unit 21, so that the adhesive dispensers 31a and 31b can be moved transversely to the label tubes 5, 6. This will be described in more detail below with reference to FIGS. 2C and 2D.
  • the second label tube 6 is held at its initial section 6c by two vacuum strips 43a, 43b which can be moved together and pulled apart.
  • the vacuum strips 43a, 43b can be moved together and apart with the actuators 42a, 42b, wherein at the contact sides vacuum openings are attached.
  • the initial straps 6a, 6b of the second label tube 6 can be sucked in.
  • the vacuum strips 43a and 43b are arranged together with the adhesive dispensers 31a, 31b on the moving part 21 and are movable together.

  • the same letters of the figure numbering correspond to the same method step, with FIGS. 2A-2D representing the process in perspective and FIGS. 3A-3D in a side, schematic view.
  • FIG. 2A it can be seen that the second label tube 6 has already been prepared by an operator, with the two longitudinal folds 6d being cut in the area of the starting section 6c (for example 20-30 mm), so that the starting tabs 6a and 6b are formed therefrom (shown in more detail in Figures 3C and 3D).
  • the initial portion 6c of the second label tube 6 is laterally applied to the stopper 24b and clamped by means of the contracted vacuum strips 43a, 43b.
  • the vacuum strips 43a, 43b are moved together with inserted starting straps 6a, 6b. Consequently, therefore, the second label tube 6 is already in a waiting position.
  • FIG. 2A, 3A shows the first label tube 5 which has been conveyed so far in the conveying direction R 3 that the end section 5 a has been reached. Since the end 5b of the label tube 5 is usually not precisely cut straight on the roll, this is now cut off with the cutting device 23 exactly perpendicular to the stop 24a or transversely to the label tube 5. This results in a particularly precise bonding. During conveyance or cutting, the adhesive dispensers 31 a, 31 b are moved apart to ensure a free passage of the label tube 5.
  • FIGS. 2B and 3B a further method step is shown, wherein the adhesive elements 7a and 7b are attached to the end section 5a of the first label tube 5 with the adhesive dispensers 31a and 31b.
  • the adhesive dispensers 31 a, 31 b are moved together in the directions R and R 2 , so that the transfer rollers 33 a, 33 b come into contact with the end portion 5 a of the first label tube 5 from both sides.
  • the first label tube 5 is moved in the conveying direction R 3 still a piece, so that the adhesive elements 7 a and 7 b are issued by the adhesive dispensers 31 a, 31 b on the end portion 5 a by pressing and rolling simultaneously.
  • the transfer rollers 33a, 33b are constructed by a suitable surface structure and / or material so that the adhesive elements 7a and 7b exert only a slight adhesive action thereon.
  • the adhesive elements 7a, 7b here consist of sections of a double-sided adhesive tape.
  • FIGS. 2C and 3C respectively, that the vacuum rests in the vacuum strips 43a, 43B, so that the two initial straps 6a and 6b of the second label tube 6 adhere thereto.
  • the vacuum strips 43a and 43b are moved apart so that a space is created between the two starting plates 6a and 6b.
  • the adhesive dispensers 31 a, 31 b have already moved apart, since the attachment of the adhesive elements 7 a and 7 b has already been completed.
  • the traversing unit 21 the adhesive dispensers 31a, 31b and the vacuum strips 43a, 43b are now moved together across the label tubes 5.6.
  • the top plates 6a, 6b are moved or positioned above and below the end section 5a of the first label tube 5 without touching each other.
  • the movement R 4 takes place here transversely to the label tubes 5.6.
  • the vacuum is switched off and the two vacuum strips 43a, 43b moved apart again.
  • the vacuum strips 43a, 43b and the adhesive dispensers 31a, 31b can be jointly returned to the starting position of FIG. 2A by means of the traversing unit 21.
  • the label tubes are glued together reliably and quickly. Due to the automated and simple process steps, the joining takes place particularly quickly and consequently only a small buffer store is required in the labeling machine for gluing in order to continue production during this time. Since the adhesive dispensers are activated by the pressing and the method of the label tube, they themselves need no actuators to promote the adhesive elements.
  • the second label tube can be gripped reliably with the vacuum strips and prepositioned in relation to the first label tube in the waiting position, so that an operator does not have to be present at the gluing station during the actual gluing.
  • the gluing station is particularly simple by the use of a common movement for the adhesive dispenser and the vacuum bars.
  • the adhesive elements are applied with the adhesive dispensers to the initial section or the starting tabs of the second label tube. It is understood that in the embodiments described above mentioned features are not limited to these specific combinations and also possible in any other combinations.
