TECHNICAL DETAILS

This machine, with painted steel structure (possible option: stainless steel)  for the automatic packaging of various types of products in trays with heat-shrinked film in single lane with linear,  90°or  180° infeed even more compact version for a greater reduction of overall dimensions .

Main machine features: 

  • Painted steel machine bearing structure (possible option: stainless steel)
  • Pneumatic product separator to enable a smooth product channelling – Minimum accumulation photocell control for each channel
  • Pneumatic product separation
  • Continuous motion bar conveyor, synchronised with the machine that leads the product directly to the winding area
  • Device for the creation of filmed bundles without tray
  • Motorised die cut pick-up from the machine
  • Tray formation unit around the product with hot-melt adhesive application unit
  • Film tension control system during uncoiling operations by means of an electronic sensor and motorised brake installed on the reel holder shaft
  • Film winding unit around the product depending on the size of the pack to be wrapped
  • Automatic controls with alarm and machine stop signals for:
    – “Minimum die cut storage accumulation”
    – “No die cut pick-up”
    – “No tray under product”
    – “Tray not glued check”
    – “No film winding”
    – “Product overturned or missing”
    – “Oven obstructed”
    “End of film reel”
  • Heat-shrinking oven consists of a metal mesh conveyor with automatic control and regulation of the temperature by digital temperature controllers and static relays
  • Electrical cabinet on the machine
  • Control panel with touch-screen colour display
  • Bundle cooling device installed at heat shrinking tunnel output

The machine can pack products both in TRAY + FILM or in ONLY FILM (through ADDITIONAL MODULE) by additional transport with automatic insertion provided for this purpose.

FURTHERMORE the TB model can also package products on FLAT FLOOR + FILM (through ADDITIONAL MODULE automatic insertion)


EXAMPLES OF PROCESSES


ADDITIONAL MODULES


OPTIONAL

PRINT REGISTRATION
Printed Film registration in the longitudinal direction is obtained by spot reading + an encoder on the film upstroke (on printed film), or encoder only (on transparent film). This data is then systematically calculated/compared by the main machine encoder to optimise and/or retrieve any film centring errors on packaging.
Print registration in the transverse direction is carried out according to the quality of the kinematic positioning / locking of the reel up to the film winding module. Also the steps on the conveyors between the film winding area and access to the tunnel/oven, made with upper transmission recovery, allow the stabilisation of packages with the film, before its retraction. 
We propose a film positioning tolerance with repeatability:
– Film side positioning tolerance: Max ±2 mm.
– Longitudinal film positioning tolerance: Max ±2 mm.

SECOND REEL HOLDER
The installation of a second reel holder shaft allows the positioning of a new reel without interrupting machine operation. It can be installed on all machine models that work with shrink film.
Advantages: reduced reel replacement times.

AUTOMATIC SEALING
Device that allows the replacement of the finished film reel with new reel in a fully automatic way and without interrupting machine operation.
The operator places the new film reel on the second shaft while the machine is operating with the first reel. At the end of the latter (detected via photocells), the device seals the new reel film and the machine continue to run without any operator intervention.
It can be installed on all machine models that work with shrink film.
Advantages: if the reel is placed correctly by the operator while the machine is running, no machine downtime is required nor any manual intervention for reel changes (except the 2/3 seconds necessary for the sealing).

REEL REPLACEMENT CARRIAGE
Painted steel carriage that allows film reel positioning with no effort by the operator. It is equipped with swiveling wheels that confer high manoeuvrability and a manual winch to safely lift the reel by applying the minimum force.
Advantages: reel transport and positioning with a minimum operator effort.

SEMI AUTOMATIC FORMAT CHANGE
This machine automatically adjusts wrap-around cardboard formation unit based on width, length, and height of the package.
It also automatically adjusts the width and the uprising  of the cardboard itself.
The other adjustments remain manual (cardboard storage, product input guides, etc.).
Advantages: very reduced format change times and with minimum manual intervention by the operator.

AUTOMATIC FORMAT CHANGE
All machine adjustments are carried out automatically in changing from one format to another.
Advantages: very reduced format change times and without manual intervention by the operator.

ANTI STATICS BAR
Anti-static bars are active anti-static devices that are based on the principle of air ionisation. In fact, once activated, the anti-static bar continuously ionises the surrounding air, thus neutralising the charge of static electricity present on the surface of the film without direct contact. 
Advantages: Eliminates any problems caused by electrostatic charging of film.
