  • the bellows can be supplied with suction air and/or compressed air via the air distributor core.
  • the supply depends on the rotary position of the label pickups.
  • the label pick-ups take a label from a label dispenser edge under suction air in a label take-over rotary position and apply it under compressed air to the fruit conveyed past in a label applicator rotary position, in which they generally point downwards.
  • Such labelers are, for example, from the documents EP 3 019 406 B1 and EP 2 356 031 B1 known.
  • the negative pressure created by the suction air is not constantly available to the label receivers during the rotation from the label takeover rotary position to the label application rotary position, but decreases again and again for a short time.

  • a plurality of suction air lines can lead from the suction air channel to the groove, it being preferably provided that the suction air lines are arranged in a common plane oriented perpendicularly to the suction air channel. Multiple lines can provide more even pressure conditions along the groove.
  • a compressed air line branching off radially from the compressed air channel can lead to a groove-free area of the outer surface of the air distributor core, i.e. to the area in which the groove connected to the suction air connection is not formed.

  • the label applicator can have a motor controllable by the control device for transverse adjustment of the label applicator on a frame along the axis of rotation of the rotary head and/or a motor controllable by the control device for driving the label transport device of the label dispensing device. Due to the transverse adjustment, if several Labelers are arranged side by side, the distances between the labelers are adjusted to each other. The distances can be adapted in particular as a function of the respective fruit or vegetable to be labeled.

It is preferred if an inner, air-permeable membrane is provided in each case, which covers the one or more air openings when compressed air is present and releases the one or more air openings when suction air is present. This supports a defined, in particular straight, extension and retraction of the bellows, since the membrane gives stability to the movement of the bellows.
  • the bellows can be slipped over the receiving sections in a non-positive manner at their end facing the rotary head by radial expansion. The bellows can then be installed and replaced easily and without tools.
  • the label dispensing device can be placed on the label applicator in such a way that a plurality of bolts provided on the label dispensing device engage in corresponding bolt receptacles formed in the label applicator. In this way, correct positioning of the label dispensing device relative to the label applicator can be achieved in a simple manner.

  • the two lateral return rollers pull the two returning carrier tape halves at a slightly higher speed than the middle label tape roller transports the incoming carrier tape. This allows the carrier tape to be tightened. A corresponding slip occurs between the roll of label tape and the carrier tape.
  • the label dispensing edge is preferably V-shaped. Such a design supports the division of the carrier tape into two halves of the carrier tape.
  • each of the two return rollers is assigned at least one counter-pressure roller, in particular a spring-loaded counter-pressure roller, with the two halves of the carrier tape being able to be passed between the respective return roller and the respective counter-pressure roller or rollers in order to pull the two returned carrier-tape halves.

Otherwise, the next step is not carried out and it is assumed that the label pick-up still holding the previous label will apply this to a fruit conveyed past during its next run through the rotary label-applying position.
  • the labeller can be designed to interrupt operation and output an error signal if the label sensor has detected several, in particular three or five, runs of a label receiver in a row that the label receiver is still holding the previous label.

Malfunctions of the labeler 11 can be avoided by the label sensor 119 .
  • the labels 99 are dispensed intermittently in steps into the rotary position of the respective label holder 35 for taking over the labels.
  • the carrier tape 101 is transported further by a distance that corresponds to the sum of the label length I and the distance a between two consecutive labels 99 on the carrier tape 101 (cf. 6 ).
  • the carrier tape 101 is always transported further by one step if the label sensor 119 has not detected that the respective label receiver 35 is still holding the previous label 99 . If, on the other hand, the label sensor 119 has detected that the respective label receiver 35 is still holding the previous label 99, the further transport of the carrier strip 101 is suspended by one step and no new label 99 is dispensed into the label takeover rotary position.
  • the affected label picker 35 can then apply the old label 99 to a fruit conveyed past during its next run through the rotary label application position.
  • the label sensor 119 If the label sensor 119 has detected that a label receiver 35 is still holding an old label 99 after several, for example three or five, runs of a label receiver, the operation of the labeler 11 is interrupted and an error signal is output. Manual intervention by operating or service personnel is then required.
  • the rotary head 29 is intermittently rotated in steps. With each step, the rotary head 29 is rotated through an angle which corresponds to dividing 360° by the number of label holders 35, ie through 72° in the present case. After each step, one of the label pickups 35 assumes the label takeover rotary position. The label pickups 35 thus each stop at least briefly in the label takeover rotary position. The detection of whether a respective Label pick-up 35 still holds an old label 99 takes place in the label take-over rotary position. In contrast, in the label-applying rotary position, the label pickups 35 do not stop, but pass through them while a respective step is being carried out.
  • the label applicator 13 has a plug 121 and the label dispensing device 15 has a socket 123 .
  • an electrical plug connection can also be established automatically between the control device and the label sensor 119, so that the control device enables the intermittent operation of the label transport device 75 depending on the respective output signal of the label sensor 119 can control.
