Definitions

  • the invention relates to a labeling device of the type specified in the preamble of claim 1.
  • a labeling device of this type is known (DE-OS 25 16 195), which operates fully pneumatically and which is primarily intended for automatic operation in rooms at risk of explosion.
  • the tape is preferred there by pulling rollers pressing against each other and against the label tape, which can be driven by a pneumatic motor.
  • the preferred mechanism is controlled by an air barrier that responds to control holes located in the label tape.
  • the automatic operation of such a labeling device repeatedly leads to malfunctions, for example because the air barrier is missing or clogged control holes in the label tape does not respond. This can lead to multiple labeling or label jams, which may make it necessary to switch off the device and the conveyor system for the objects to be labeled.
  • there are geared motors that are subject to constant alternating stress both for the preferred mechanism and for a possible tape rewinder, which require frequent maintenance because of the unavoidable susceptibility to wear, especially during continuous operation.
  • the pull-off roller braked by a friction member is driven by the pulling-off label tape, while the take-up roller for the empty label tape can be driven by means of a specially provided motor.
  • a stationary belt clamping device which can be actuated in opposition to it, is arranged, which is intended to prevent tape withdrawal v 3 n of the winding roll when the movable belt clamping device is moved back.
  • the movable belt clamping device can detach itself from an adhering adhesive tape when moving back with open clamping jaws, this is not the case with the stationary belt clamping device, so that there is a slight build-up of jam and thus when feeding due to the bending slackness of the carrier tape serious operational disturbances can occur.
  • the invention has for its object to improve the known labeling device of the type specified in the preamble of claim 1 with respect to its drive and control mechanism in such a way that a reliable full even if individual control markings fail automatic operation is guaranteed.
  • the preferred mechanism according to the invention with its linearly displaceable tape clamping device by means of which the label advance can be controlled both via the scanning device and also via the redundant switching device, which is preferably designed as a mechanical limit switch valve, also ensures trouble-free operation if there are occasionally missing control markings in the label tape.
  • the tape tensioning mechanism acting on the take-up reel and the backstop enable the tape clamping device to be pushed back reliably without the unwanted label tape possibly being unwantedly taken back with it.
  • the tape tension required for reliable operation is obtained according to a preferred embodiment of the invention in that the take-up roll is connected via a transmission gear containing a slip clutch to the take-off roll which can be driven by the pulling-off label tape essentially without slippage.
  • the over corresponds setting of the transmission gear at least the ratio between the tape winding diameters of the empty take-up roll and the full take-off roll.
  • the transmission gear can be designed as a belt drive, chain transmission or gear transmission, while the slip clutch can be formed by a slip hub coupling the pull-off roller with the associated belt or driven pulley.
  • a freewheel is preferably provided as a backstop on the side of the winding roll.
  • the drawing shows two advantageous exemplary embodiments of the invention in a schematic manner.
  • the labeling systems shown schematically in the drawing essentially consist of one above a conveyor track 2 for the transport of the objects 4 to be labeled arranged labeling device 6, in which, with the aid of a pneumatically operating preferred mechanism 8, a tape 12 carrying self-adhesive labels 10 is pulled off a supply and take-off roller 14, pulled past a pneumatically actuated printing unit 16, an air barrier 18, a dispensing edge 20 and a pneumatically actuated pressing mechanism 22 and is wound on a take-up reel 23.
  • the labeling process including tape advance and printing process, is triggered via a trigger mechanism 24 which is mechanically actuated by the objects to be labeled and is arranged in the region of the conveyor track.
  • the objects to be labeled are beer kegs 4 which are transported upright on a roller conveyor 2 and which are to be labeled on their lid as precisely as possible next to the bunghole.
  • the label tape 12 coming from the take-off roller 14 passes via a deflection roller 26 and through the printing station 16 'to the scanning device 18, which consists of an air barrier at which a transmission nozzle 28 and a receiver nozzle 30 are arranged opposite to each other on a fork-shaped part.
  • the label strip 12 has holes 32 at the label spacing, as shown in FIG. 4.
  • the label tape is preferred step by step, whereas the step size is normally controlled via the air barrier 18 by scanning the holes 32.
  • the label strip 12 with the labels 10 pointing upwards arrives at the sharp-edged dispensing edge 20, at which it is deflected such that the label 10 'previously arranged on the strip is detached from the base and a little further over the dispensing edge is pushed forward while the empty carrier tape 12 'is pulled down at an acute angle.
  • the label 10 'released is sucked in via suction air openings in the free lower surface of the stamp 40 * of the pressing mechanism 22 and held there by the suction effect.
  • the punch 40 is arranged at the end of a piston rod 42 of a relatively long pneumatic cylinder 44.
  • the preferred mechanism 8 contains a pneumatic belt clamping device 50 which can be moved back and forth by means of a pneumatic cylinder 46 in the direction of the double arrow 48 and which is controlled in such a way that during the forward movement it presses the empty carrier belt 12 ' Clamping claw 52 holds and takes with it while it is open when moving back.
  • the preferred path of the label tape is normally controlled by the air barrier 18, which emits a signal to open the tape clamp 50 in the presence of a hole 32 in the label edge.
  • holes 32 are not punched out or not completely punched out and are therefore not detected by the air barrier 18.
  • a redundant limit switch valve 54 is additionally provided, which can be mechanically actuated directly by the belt clamping device 50 and which reverses the belt clamping device 50 after an adjustable feed path has been reached.
  • the output signals of the switching valve 54 and the air barrier 18 are linked to one another via an OR logic 56.
  • a stationary band clamping device 58 which can be actuated in opposition to the latter and which is intended to ensure that the empty carrier tape 12 'reaches the winding roll 23 freely when it is pulled forward and when the movable band is moved back Band clamping device 50 is not inadvertently taken back by it.
  • the symbols S and O indicate the inputs for closing and opening the two belt clamps and the two below centering barriers 70 explained.
  • the stationary tape clamping device is omitted in the labeling device shown in FIG. Instead, a backstop 82, 83 is provided on the take-up reel 23, which ensures that the carrier tape wound on the take-up reel cannot be pulled off again.
  • the backstop is indicated for the sake of simplicity as spring-loaded pawl 83 engaging in a circumferential toothing 82 of the winding roller 23. It is more appropriate to use a freewheel, not shown, as a backstop, which enables a continuous winding.
  • FIGS. 1 and 1 a Another difference between the exemplary embodiments shown in FIGS. 1 and 1 a is the type of reversal of the movable belt clamping device: while in the case of FIG. 1, the reversal of the direction of movement is triggered simultaneously with the opening of the belt clamping device via the output signal of the OR gate 56 , in the case of FIG. 1 a, the reversal of the direction of movement takes place solely via the output signal of the limit switch valve 54, after the band clamp has normally been opened shortly before via the air barrier by actuation via the OR gate and the band advance has thus been interrupted. With the latter arrangement, one obtains a more reliable switching sequence in the reversal. In both cases, the feed path of the movable tape clamping device up to the limit switch valve 54 is to be set slightly larger than the label spacing on the carrier tape.
  • the take-off roller 14 is driven in a largely slip-free manner in the direction of the arrow 60 via the label tape 12 drawn off by the preferred mechanism 8. It is coupled to the pulley 64 via a sliding hub, not shown, which in turn is connected via a belt drive 63 to the pulley 66 of the winding roller 23 so that the winding roller is driven in the direction of arrow 62.
  • the ratio defined by the different diameters of the pulleys 64 and 66 is selected so that the empty take-up roll 23 also full take-off roller 14 is driven with the angular speed necessary for tight winding.
  • the aforementioned slip hub ensures that a certain band tension is constantly maintained during winding.
  • the labeling process is triggered by two switching valves of the trigger mechanism 24, identified by the symbols A and B, which are activated by means of two levers 72 A, which engage laterally in the roller track 2, are hinged to centering barriers 70 and arrive at the driven roller track 4 and can be pivoted against the centering barriers. 72 B can be operated.
  • the AND gate 74 causes the labeling process to be triggered only when both switching valves A, B are actuated simultaneously, which means that the barrel 4 is correctly centered. Thereafter, the stamp 40 is first moved obliquely downward by moving the piston rod 42 until it strikes the drum cover with its lower surface carrying the self-adhesive label 10 '.
  • the stamp is articulated on a transverse axis of the piston rod and connected to it via several independently compressible or expandable coil springs 41 and consists in its lower part of an elastic material, for example Foam.
  • a pressure switching valve 76 which is acted upon by the internal pressure of the cylinder 44 engages is made, the stamp 40 is pulled back into its starting position, while the self-adhesive label 10 'adheres to the drum lid.
  • the plunger 40 In its upper end position, the plunger 40 actuates a switching valve 78 via an organ connected to it, via which both the centering racks 70 and the pneumatic cylinder 46 and the belt clamp 50 of the preferred mechanism 8 and, in the case of FIG. 1, the belt clamp 58 are controlled .
  • the labeled barrel 4 is released for further transport by opening the centering barriers 70.
  • the renewed closing of the centering barriers 70 is triggered by a light barrier 80 which emits a signal when the labeled barrel has left the area of the centering barriers.
  • the label tape 12 is pulled forward by a hole spacing while detaching a new label 10 'for the stamp 40.
  • the label 10 that has come under the printing unit 16 is then printed.
  • the system is then ready for a further labeling process which is triggered by the next drum.
