Tray packers


TF 400 ERGON - Tray formers up to 40 ppm

The new ERGON range of automatic packers is based on design choices inspired by key concepts such as ergonomics, technology, sturdiness and modularity, masterfully blended to mark a new, significant evolution in the history of SMI products.

You can point out the new ERGON packers rather quickly due to the rounded profile of the movable safety guards, which allow to house all the motors on the outside with respect to the mechanical units they run, facilitating line operator access when performing maintenance.

The TF ERGON series includes automatic machines for the packaging of plastic, metal and glass containers in cardboard trays without film. Trays can be octagonal or rectangular, with walls having the same height.

TF ERGON series' tray formers can achieve outputs up to 80 packs per minute, according to the machine model and to the product to be packaged. The pack collations can vary according to the containers shape and size; in general, the most frequently requested collations are 2x2, 3x2, 4x3 and 6x4.

All TF ERGON models feature an electronic grouping system; the change-over is hand-operated.

1In the machine infeed zone, an oscillating unscrambler accurately lines up the loose containers carried by a conveyor belt featuring low-friction chains made of thermoplastic material. In the pack formation zone, the containers are clustered in the required format through a pneumatic device operating in alternate motion.


2A corrugated cardboard blank is picked from the blanks magazine by an alternate motion picker composed of a group of vacuum suckers. The pad or the blank moves along the blank climb and gently places itself underneath the group of products in transit with the long side leading.


3In the tray former, special mechanical devices fold the blank’s front and rear flaps. The side flaps are sprayed with hot melt glue and then folded, thus forming the tray.


4The packs coming out of the tray former can be conveyed either to the palletizer or directly to the storage area.

  • The machine is equipped with sliding protection doors in anodised aluminium featuring a rounded shape which let all the motors (featuring low energy consumption) be placed externally if compared to the mechanical groups they activate. The closing system of doors is equipped with a slow-down device, which accompanies the door smoothly in its final phase of closure
  • Absence of gearboxes and prevailing employment of ICOS brushless motors equipped with digital servo-driver integrated into the motor
  • For life lubricated bearings
  • Infeed conveyor with chains made of thermoplastic material featuring low friction coefficient and a motorized system of oscillanting laning guides
  • Cardboard magazine situated beneath the infeed conveyor in an easily accessible position (P and T models)
  • Alternate motion cardboard blank picker, equipped with suckers
  • Interactive 15'' touchscreen display and operator panel mounted on an arm sliding on a rail

Modular design

SMI machines are designed according to advanced principles of module assembly and feature interchangeable mechanical and electronic components, which ensure a reduction of the down-times during technical interventions or programmed maintenance and the optimization of the use of spare parts on stock.

Operational flexibility

SMI machines can package a wide range of products in several pack collations, so as to effectively meet the end user's current and future requirements. Moreover, each machine can be equipped with additional devices, which increase its basic functions and ensure a high level of customization of the final package.

Motors directly connected to the drive shafts

SMI machines do not include gearboxes: the motors are directly connected to the drive shafts. The consequent advantage is the reduction of maintenance, energy consumption and noise.

Easy and low-cost maintenance

The rounded protection doors of ERGON models allow broader space inside the machine and thus the motors can be mounted externally on the machine side edges. Therefore, they are easily accessible and reachable for maintenance. Actually, the operator doesn't need to enter the internal parts of the shrink wrapper when carrying out manual interventions.

Trays for all needs

All TF models can pack products in cardboard trays with 90° edges or in octagonal trays . Therefore, the final user can choose the most suitable solution for customizing, distributing and palletizing the pack.

User-friendly man-machine interface

The POSYC® control panel, fixed or sliding on a boom running the whole length of the machine (depending on the machine model), enables even less expert operators to easily and effectively run the packer, thanks to an intuitive interface, a touch screen display and diagnosis functions and real-time technical support available on the POSYC®.

Pallet display tray

Cardboard multipack sleevers

Wrap-around case packers of the WP series and shrink wrappers of the SK series can be predisposed in order to produce, in addition to standard packs in corrugated board boxes / trays or in shrink film bundles (with or without tray), also the so called "pallet displays", e.g. large trays in corrugated board measuring ¼ (WP and SK) and ½ europallet (WP) size.

These collations allow to get remarkable advantages: • better use of the space available on the pallet • huge savings in the packaging material • reduction of storage and transportation costs • low energy consumption • easier handling of the pallet at the points of sale.

It is a very innovative choice, if we consider that, presently, the production of these types of packaging solutions requires the use of two different machines: one for the production of cardboard cases in standard formats of 6, 12, 15 and 24 pieces, and another one for the packaging of a huge number of bottles in trays whose size is equal to ¼ or ½ europallet (½ europallet = until 80 bottles).
