SKL MACHINE

Labeling machines for shrink sleeves with 1 or 2 heads in line + shrinking tunnel

The series of Shrink Sleeve Labellers covers a wide range of speeds from 3,000 up to 48,000 cph and is divided into three groups of machines that differ essentially due to the different configuration of the sleeve insertion unit.:
1) In Line direct shooting Shrink Sleeve Labeling Machines; production speed up to 18.000 cph (See)

CLOSE UP SKL 100

2) In Line Shrink Sleeve Labeling Machine with rotating carousel; production speed up to 24.000 cph; (See)

3) In-line double head Shrink Sleeve Labeling Machine for speeds up to 48.000 cph

The bottles coming from the line are continuously fed and sufficiently spaced for the insertion of the sleeve. To seperate the sleeve from the reel we perform a pre-cut by a perforation across the sleeve web at register;

therefore the pre-perforated tubular fed to the application head, in a flat shape opened and shaped on a mandrel in the shape required by the container to be labeled, has a minimal abundance in perimeter allowing a very low energy consumption and minimum lay flat.

 

Finally the sleeve is thermally retracted inside the tunnel.

  • The HIGH SPEED models are equipped with a rotating carousel mechanically synchronized with the bottles, which allows high production speeds to be obtained even with an extremely simple and compact linear configuration. This system also allows the use of very thin materials (20 mµ), with very high energy savings and / or materials to be disposed of and / or carbon footprint.
  • Differently to most of the shrink sleeve machines already on the market, our machine features an alternative solution to the traditional cutting of the sleeve by means of rotating blades around a cylindrical mandrel.
  • To achieve the separation of one sleeve from the other, the sleeve tubular, in its original flat form, is fed into a couple of parallel shafts with toothed blades that carry out the pre-perforation of the sleeve (transversal to the advancing direction) in the middle of the transparent zone typically left unprinted between one sleeve and the other.
  • This cutting system, working on the flattened tubular, does not require size adjustments as the width of the sleeve varies. The cutting length is self-adjusting thanks to the reading of the transparent interval between one sleeve and the other. In no case will there be visible teeth marks or signs of breakage along the sleeve cutting line
  • Furthermore, the advancement of the sleeves takes place at a constant and continuous speed, as the system does not require stopping, cutting and restarting like traditional systems with rotating knives around the mandrel. After the pre-perforation, the tubular is then opened by a very simple and light shaping mandrel, suspended on two pairs of rubber nip rollers actioned by electronic servomotors.
  • Downstream the first couple of rollers, aother second couple of rollers, by means of a speed difference, separate the sleeve along the pre-perforation and fit it onto the contianers passing under the applying head.
  • This is a very simple and effective solution, with which the parts of format to be replaced are reduced to just the conforming mandrel, in addition to the infeed timing screw. This system, when required by a particularly elongated shape of the bottle section, also allows the use of conforming mandrels with elliptical shapes.
  • The shaping of the mandrel allows to optimize the dimensions of the sleeve with respect to the contour of the bottle, reducing to the minimum the percentage of shrinking necessary.
  • 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
  • Bottles drying tunnel with air knives to remove the moisture on the bottles
  • The machine can be equipped with a Plug-On Head which allows the immediate change over of the applying head, complete with its sleeve shaping mandrel.
  • This version is especially suitable for cases where the downtime for the format change over must be reduced to the minimum and is needed quite often. No mechanical adjustment is required: each unit, with its conforming mandrel, is dedicated and pre-set to its format. The operator can easily recall the PLC software settings associated with the format from the touch screen panel. The complete format change can be completed in a few minutes.
