ISLa MACHINE

Rotary labeling machines for shrink sleeves with integrated thermoshrinking

The ISLa (Integrated Shrink Labeler) rotary machines apply and shrink the sleeves in a single structure that includes the tunnel, taking up very little space (less than about 2×2 meters):

the container (either full or empty) is labelled and immediately treated individually in a series of closed chambers, where a jet of steam of variable-duration causes the label to shrink on the container. See
This innovative technique allows reducing steam consumption up to 10 times compared to the traditional shrink tunnels, and in addition the steam stops – and is not consumed uselessly – when the machine is in standby.


There are two different types of ISLa that share the integrated shrinking system, but the methods for applying the sleeve are very different:

The first system, called INDIRECT, shoots the sleeve first on a so called expander when it is closed making the label feeding on it very simple; then the expanders open up to keep the sleeve in the needed shape to allow the bottle to easily enter into the sleeve without difficulty in a progressive movement.(See)

 

In the second DIRECT system, the label is directly shot on the bottle and there are no expanders.
We have made this second version available to reduce some costs for low-speed applications. (See)

  • High speed rotary system
  • Direct Shooting (DIRECT) or Expander (INDIRECT) depending on the speed and the product to be labeled
  • Space reduction due to the absence of a shrink tunnel which is integrated into the central rotor of the machine, consisting of a series of cylinders mounted on the labeling machine carousel, in which a jet of pressurized steam is injected
  • Very compact machine; with less than 2 meters of space in the line it is possible to insert a machine of over 24,000 bph when for a labeling machine + intermediate conveyor + tunnel it would be necessary not less than 10 – 12 meters
  • Extremely accurate positioning of the label: the label is transferred to the bottle with a progressive and mechanically determined movement. with absolutely precise positioning of the final position of the label on the bottle, which is also maintained in the shrinking phase, immediately following, allowing the label to be partially positioned under the base to completely eliminate the SMILE effect
  • Low consumption – the amount of steam required is up to 10 times lower than traditional steam tunnels and is directly proportional to the production speed. No preheating is required and there is no steam consumption when the machine is in stand-by. Furthermore, the system guarantees the absence of steam dispersion in the work environment
  • The reduced exposure time to heat and the minimum quantity of steam required for shrinking, make the process particularly suitable for products that do not withstand high temperatures and allow to work indifferently both full and empty containers (as well as wet or with condensation) even with very thin walls
  • No brushes are necessary for the positioning of the label and the shrinkng phase is immediately after the posiitoning of the sleeve on the bottle. In this way the orientation of the sleeve cannot be compromised in the transport from the machine to the tunnel
  • Perfect shrinking on every shape and size; each bottle is treated individually in a series of closed chambers where a jet of steam, quickly saturating the internal chamber area, realizes the perfect and immediate shrinking of the sleeve on the bottle, eliminating any problem of regulation and management of the tunnel
  • Immediate achievement of full production after a format change: each format has its own retraction cylinder designed according to the design of the bottle. Therefore, after the normal format changeover operations, the machine is immediately ready to go into production without further adjustments. Furthermore, both the steam injection time and the pressure are controlled by the PLC and therefore associated with each format
  • There are no temperature variations due to fluctuations in the flow of containers, typical of linear tunnels
  • The system also allows labeling of empty containers

The INDIRECT sleever can work without problems on bottles wet by moisture and no noisy and expensive drying units are needed on the line before the labeling machine.
On the INDIRETTA machine the sleeve enters the container progressively and smoothly, and this allows the use of low thickness films (we tested the machine up to 20 microns!). This point is very important for all environmental issues, for the reduced weight of the labels and for the low energy required for shrinkage.

  • Possibility of installing two applicator heads connected to a filler with a double product tank.
  • The machine can apply two different series of labels in succession. For example: 12 bottles with type A sleeve followed by 12 bottles with type B sleeves.
  • Transversal Perforator for partial removal of the sleeve (needed when the sleeve extends over the cap/closure for tamper evident seal function)
  • Non-stop sleeve feeder:
  • It is possible to equip the machine with a buffered sleeve feeding system, separate from the machine, that allows the operator to carry out the reloading of the reels by coupling the reel that finishes with a new one without stopping the machine
