Definitions

  • the invention relates to a labeling machine for open containers, in particular cups, according to the preamble of claim 1.
  • the invention has for its object to increase the performance in the generic labeling machine with simple means and to avoid disruptions in container transport.
  • the relative movement between the mandrel and the support creates the possibility of gently and safely placing the container on the mandrel or lifting it off the mandrel even with a continuously rotating rotary table. This enables significantly higher outputs and disruptions in container transport, e.g. by skewing or tilting are reliably avoided.
  • the labeling machine 1 is set up for labeling open, conical cups 2 made of plastic, as are used for example for yogurt. It has a housing 17, on the top of which a rotary table 3, an inlet star 10 and an outlet star 12, all with a vertical axis of rotation, and a labeling device 5 in the form of a dispenser for self-adhesive labels are arranged.
  • the turntable 3, the Inlet star 10 and outlet star 12 are continuously driven in the arrow direction by drive devices, not shown, within the housing 17.
  • a plurality of shafts 8 with a polygonal cross-section are rotatably distributed evenly over the circumference, namely parallel to the axis of rotation of the rotary table 3.
  • an upwardly tapering mandrel 4 with a correspondingly polygonal bore is accommodated in a vertically displaceable manner.
  • a first cam control 15 which, when the turntable 3 rotates, gives the shafts 8 or thorns 4 in the area of the labeling device 5 and, if necessary, label pressing elements (not shown) the desired rotary or pivoting movement.
  • a second cam control 16 is provided which, when the rotary table 3 rotates, gives the mandrels 4 the desired lifting movement in the area of the inlet star 10 and outlet star 12.
  • Each mandrel 4 is assigned an annular receptacle 6 for the open, lower edge of a cup 2, which is arranged concentrically to the mandrel 4 without being connected to it.
  • the receptacles 6 are attached to the upper ends of vertical rods 18 such that they are fixed in height in a common horizontal transport plane.
  • a raised, rounded centering surface 7 is formed, which is circular in accordance with the outer rim of the cup and encompasses this with a slight play.
  • the height of the centering surfaces 7 is relatively low, so that, in conjunction with their rounding or beveling, the cups 2 can easily slip into and out of the receptacles 6.
  • a U-shaped slide 19 is mounted in a vertically movable manner on the parallel rods 18, each belonging to a receptacle 6, which are fastened on the turntable 3. This engages on the one hand by means of lugs in an annular groove on the associated mandrel 4 and on the other hand by means of a roller 27 in a fixed stroke curve 20.
  • the last-mentioned parts form the second cam control 16 of the lifting rotary gear 9.
  • the first cam control 15 also has a fixed groove curve 21, in which roller levers 28 connected to the shafts 8 engage via gear mechanisms.
  • the stroke curve 20 and the groove curve 21 are shaped such that the function of the labeling machine 1 described below is established.
  • Each mandrel 4 has a central bore with an opening 14 opening into the upper end face. This is connected via a further central bore in the shaft 8 and a transverse bore to a rotary distributor 22 arranged on the turntable 3.
  • the rotary distributors 22 of all mandrels 4 are connected to a central distributor 24 which is arranged concentrically to the axis of rotation of the rotary table 3 and which optionally connects them to a vacuum source, a compressed air source or the atmosphere at the desired points in their orbit.
  • the central distributor 24 is designed such that the following function of the labeling machine 1 results.
  • the cups 2 which are stacked in the form of a vertical column with the opening facing downward, are thrown into its pockets by a conventional metering device 23, which is arranged in a stationary manner above the inlet star 10.
  • the allocation device 23 has, for example, a plurality of vertical screw conveyors, not shown, which are driven synchronously with the inlet star 10 and which insert the cups 2 exactly into the inlet star 10 in accordance with the division. Its pockets are expanded in the circumferential direction compared to the cross section of the cups 2, so that there is sufficient time for the cups 2 to be supplied.
  • the cups 2 are then transported through the pockets of the inlet star 10 to the rotary table 3, with their open edge region resting on the flat sliding surface 11 and being guided exactly by a stationary guide bend 25 arranged between the inlet star 10 and the outlet star 12.
  • the sliding surface 11 lies at the level of the upper edge of the centering surface 7 of the receptacles 6.
  • each cup 2 is pushed exactly over a receptacle 6, after which it sinks between the centering surface 7 and rests with its lower edge on the receptacle 6.
  • the corresponding mandrel 4 assumes its lower end position shown in FIG. 2 on the right-hand side, in which it is completely lowered under its receptacle 6 and its opening 14 is connected to the atmosphere. Instead, it is also possible to align the upper end face of the mandrel 4 with the upper edge of the centering surface 7.
  • the mandrel 4 is now connected to the vacuum source in order to securely position the cup 2 and, under the action of the second cam control 16, it is raised above the intermediate position shown in the middle in FIG. 2 to the upper end position shown on the left.
  • the cup 2 in question is lifted somewhat from the receptacle 6 and then carried exclusively by the mandrel 4, held in place by the vacuum which continues to act at the opening 14.
  • the mandrel 4 with the attached and sucked-in cup 2 passes the labeling device 5, where it is given a pivoting movement in the circumferential direction under the influence of the first cam control 15.
  • a self-adhesive label is attached to the wall of the cup 2 and pressed on, if necessary under the action of additional pressure rollers or the like.
  • the vacuum at the opening 14 is now switched off and the mandrel is lowered, as shown in FIG. 2, from the upper end position via an intermediate position to the lower end position.
  • compressed air is temporarily supplied to the opening 14.
  • the cup 2 hits the receptacle 6 with its lower edge and is fixed there by the centering surface 7.
  • the receptacle 6 with the cup 2 now runs to the outlet star 12, where the cup 2 through the guide bend 25 out of the receptacle 6 over the centering surface 7 onto the outlet-side sliding surface 13 and thereby into a pocket of the outlet star 12 is introduced.
  • the sliding surface 11 is in turn arranged at the level of the upper edge of the centering surface 7.
  • the labeled cup 2 is fed to a conveyor belt 26 which removes the cups 2.
  • the corresponding mandrel 4 is located completely below the receptacle 6 and is connected to the atmosphere, so that it does not influence this process.
  • the mandrel 4 remains in its lower end position until it begins to rise again after a cup 2 has been placed on its receptacle 6.
