Wrap-around casepackers

LWP ERGON Series

LWP 30 ERGON - Wrap-around casepackers up to 30 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 LWP ERGON series includes automatic machines for the packaging of plastic, metal , cardboard and glass containers in corrugated cardboard cases and/or trays without film. The octagonal or rectangular trays can have walls of either the same height or different heights.

The LWP ERGON series casepackers can achieve an output up to 30 packs per minute, according to the product.

The pack collations can vary according to the containers shape and dimensions; in general, the most requested collations are: 2x3, 3x4 and 4x6.

LWP ERGON casepackers are equipped with a mechanical product grouping system and are supplied with an in-line or a 90° infeed conveyour, depending on the customer’s exigencies. The change-over is manual.

1In the machine infeed zone, a group of guides accurately lines up the loose containers carried by a conveyour belt featuring low-friction chains made of thermoplastic material. In the pack formation zone, the containers are clustered in the required format through electronically synchronized fingers and dividing bars, operating in continuous motion.

2A corrugated cardboard blank is picked from the blanks magazine by an alternate motion cardboard blank picker composed of a group of suction cups, moves along the blank climb and places itself underneath the group of products in transit with the short side leading. In the tray/case former, the cardboard blank is folded and wrapped around the products by special guides.

3The flap folding devices fold the blank’s side flaps and then the upper/lower flaps of both the front and back side of the pack. The hot melt glue sealing ensures an excellent resistance of the pack.

4At the machine outlet, the pack walls are pressed by special guides that guarantees a perfect and lasting squaring of the cases. Such system ensures perfect and durable pack squaring, if compared to pressing systems with rotating chains, which cannot provide the same quality standard.


  • Machine bearing frame made of sand-blasted and powder-painted steel
  • 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 pads
  • 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 conveyour, adjustable according to the blank size
  • Alternate motion cardboard blank picker, equipped with suckers
  • POSYC® control panel mounted man-high and running the whole length of the machine (fixed on AFW/LSK/LWP models)

Compact size and competitive prices

Thanks to their reduced size, the ERGON machines are the ideal solution for the customers who do not possess large plants. Moreover, the price of the ERGON models is very competitive, despite the high-tech solutions and the use of very reliable components. All ERGON models can be customized, in order to increase their basic functions.

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 shrinkwrapper when carrying out manual interventions.

User-friendly man-machine interface

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

Perfect cases

The LWP casepackers are equipped with fixed guides, which press the pack walls at the machine outlet. This system ensures a perfectly balanced, resistant case, whereas the rotary chain pressing systems can not guarantee the same quality level.

"User-friendly" man-machine interface

The POSYC® control panel, sliding on a boom running the whole length the machine, is very easy to use, thanks to the intuitive interface, the touch screen and the diagnosis functions and real-time technical support on the POSYC®.
