She instructs Housing 17 on the top of which a turntable 3, a Inlet star 10 and an outlet star 12, all with vertical Axis of rotation, and a labeling station 5 in the form of a Dispensers for self-adhesive labels are arranged. Of the Turntable 3, the inlet star 10 and the outlet star 12 are within drive means, not shown of the housing 17 continuously driven in the direction of the arrow.
  • In the turntable 3 are evenly distributed over the circumference several shafts 8 with a polygonal cross section rotatable stored and parallel to the axis of rotation of the turntable 3.
  • On each shaft 8 is a conical upwards tapering mandrel 4 with a correspondingly polygonal Bore height adjustable added.
  • Within the A first cam control 15 is arranged on the rotary table 3, which, when the rotary table 3 rotates, the shafts 8 or Thorns 4 in the area of the labeling station 5 and possibly not shown label pressing organs the desired rotary or Swivel movement granted.
  • a second cam control 16 is provided, which at one revolution of the rotary table 3 the thorns 4 in the area of Inlet star 10 and outlet star 12 the desired Lift movement issued.
  • Each mandrel 4 is an annular receptacle 6 for the assigned to the open, lower edge of a cup 2, the arranged concentrically to the mandrel 4 without connection to it is. 2 shows, the recordings 6 are on the upper Fixed ends of vertical rods 18 such that they fixed in height in a common horizontal transport level lie. At the outer edge of the circular receptacles 6 is an increased, rounded centering surface 7 is formed is circular according to the outer rim of the cup and includes this with easy play. Through the centering surface 7 the cups 2 are thus exactly opposite in the receptacle 6 the thorns 4 aligned. The height of the centering surfaces 7 is relatively low, so that, in connection with their rounding or Bevel, the cups 2 slightly into the receptacles 6 or can slip out of these.
  • a U-shaped carriage 19 On the parallel to each receptacle 6 Rods 18, which are attached to the turntable 3, is a U-shaped carriage 19 is mounted so as to be vertically movable. This engages in an annular groove on the one hand by means of lugs associated mandrel 4 and on the other hand by means of a roller 27 in a fixed stroke curve 20 a.
  • the latter parts form the second cam control 16 of the lifting rotary gear 9.
  • the first cam controller 15 also has a fixed one Groove curve 21, in which gear with the shaft 8 engage connected roller lever 28.
  • the stroke curve 20 and the Groove curve 21 are shaped such that the further below sets described function of the labeling machine 1.
  • Each mandrel 4 has a central bore with one in the upper end face opening opening 14. This is over another central bore in shaft 8 and one Cross hole with a arranged on the turntable 3 Rotary distributor 22 connected.
  • the rotary distributor 22 of all mandrels 4 are concentric with the axis of rotation of the turntable 3 arranged central distributor 24 in connection of them to the desired points of your orbit with either Vacuum source, a compressed air source or the atmosphere connects.
  • the central distributor 24 is designed such that the following function of the labeling machine 1 results.
  • Allotment devices 23 In normal labeling, they are in the form of a vertical column with opening pointing downwards stacked cup 2 by a conventional one Allotment device 23, which is stationary over the inlet star 10 is arranged, thrown into the pockets.
  • the Allotment device 23 does not have several, for example shown, driven synchronously to the inlet star 10 vertical screw conveyors, which the cups 2 Insert exactly into the inlet star 10 according to the division. Its pockets are in relation to the cross section of the cup 2 in Orbital direction expanded so that there is sufficient time for the Feed the cup 2 is available.
  • each cup 2 is exactly centered over a Recording 6 pushed, after which he between the centering surface 7th sinks and with its lower edge on the recording 6 lies on.
  • the corresponding mandrel 4 takes its in 2 a lower end position shown on the right, in which it is completely lowered under its receptacle 6 and its opening 14 is connected to the atmosphere. Instead of which is also possible, the upper end face of the mandrel 4th to align with the upper edge of the centering surface 7.
  • the vacuum at the opening 14 is now switched off and the mandrel is reversed as shown in Fig. 2 from the upper end position via an intermediate position in the lower End position lowered.
  • This will temporarily facilitate compressed air Opening 14 fed.
  • the cup 2 meets with its lower edge again Recording 6 and is there through the centering surface 7th fixed.
  • the receptacle 6 with the cup 2 now runs to Outlet star 12, where the cup 2 through the guide arc 25th out of the receptacle 6 over the centering surface 7 on the outlet-side sliding surface 13 and thereby in a Pocket of the outlet star 12 is passed.
  • the Sliding surface 11 is in turn at the level of the upper edge of the Centering surface 7 arranged.
  • the Sliding surface 13 and the guide sheet 25 is the labeled Bucket 2 to a conveyor belt 26 that removes the buckets 2 fed.
  • the corresponding mandrel 4 completely below the shot 6 and is with the atmosphere connected so that it does not affect this process.
  • the mandrel 4 remains in its lower end position until it after placing a cup 2 on its receptacle 6 again begins with its rise.
  • the labeling station 5 (FIG. 3) has a transfer drum 33 with a conically shaped surface 37 and a Label feed station 40, which consists essentially of a the outer surface tangent dispensing edge 32 and one controlled driven intermittently Label tape feed device (not shown) for the adhesive labels 30 attached to a carrier tape 31, so-called self-adhesive labels.
  • a transfer drum 33 with a conically shaped surface 37 and a Label feed station 40, which consists essentially of a the outer surface tangent dispensing edge 32 and one controlled driven intermittently Label tape feed device (not shown) for the adhesive labels 30 attached to a carrier tape 31, so-called self-adhesive labels.
  • Dispensing edge 32 detach the individual label blanks from the carrier tape 31.
  • Vacuum bores 36 are not directly in the lateral surface 37 the transfer drum, but each on one strip-shaped slide 34, which in the conical Shell surface 37 substantially transversely to the plane of rotation E (Fig.4) of the transfer drum 33 can be moved in a controlled manner is stored and its surface is flush with the outer surface lies or protrudes slightly radially outwards is trained.
  • the control of the slide 34 is carried out by an inside of the transfer drum arranged in a rotationally fixed control curve 38 (Groove curve) in connection with a the control curve sensing control connected to the slider 34 39, e.g. Cam roller, depending on the rotational position of the Transfer drum.

At this moment the label is removed by interrupting the Vacuum released in the corresponding vacuum slide or by transferring compressed air to the cup supported. These operations are done in a known manner controlled so that on a more detailed description is waived.
  • ⁇ Label tape running direction L depends as well as the taper the transfer drum 33 from the taper of the labeling cup 2, since this also the angle of leading label edge 30a of an upper and lower all-round label with curved label edge 30 determined with respect to the running direction L of the carrier tape 31.
  • ⁇ Label tape running direction L depends as well as the taper the transfer drum 33 from the taper of the labeling cup 2, since this also the angle of leading label edge 30a of an upper and lower all-round label with curved label edge 30 determined with respect to the running direction L of the carrier tape 31.
  • the control curve 38 of the vacuum slide 34 is designed that a vacuum slide 34 when passing the dispensing edge 32 during the complete dispensing of a label 30 in Direction S from top to bottom across the plane of rotation E in the Lateral surface along a surface line of the transfer drum see above the procedure is that between the dispensed label 30 and the assigned vacuum slide is synchronized, i.e. no position or orientation of the label on the Relative movement influencing the transfer drum is present.
  • the vacuum gate valves are reached before Dispensing edge back up to its starting position pushed back.
  • Dispensing edge tapering label tape to circulation level E inclined not only that Dispensing edge tapering label tape to circulation level E inclined, but also the dispensing edge 32 is at the angle ⁇ for the longitudinal extension or guide axis of the vacuum slide 34 inclined.
  • This solution enables one to run up Label tape 31 parallel return of the label-free Carrier tape 31 'to a take-up reel. Because of the better Overview is the carrier tape 31, 31 'and the dispensing edge 32 4 only shown with dashed lines Dispensing edge could also be parallel to the vacuum slides and the leading label edge 30a are aligned, the dispensing edge then with respect to the Label tape running direction L would be positioned at an oblique angle.
