Combined packers

CM ERGON Series

CM 800 ERGON - Combined machines up to 80 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 CM ERGON series includes automatic machines gathering into a single unit the functions of a wrap-around casepacker and of a shrinkwrapper, for the packaging of plastic, metal, cardboard or glass containers in the following package types: cardboard case, cardboard tray + film and cardboard tray without film.

Trays can be octagonal or rectangular, with walls having either the same height or different heights.

CM ERGON series machines can achieve an output up to 80 packs per minute, according to the machine model, the product kind and the selected format. The pack collations can vary according to the containers shape and dimensions; in general, the most requested collations are: 2x3, 3x4 and 4x6 for wrap-around cases and 4x3 and 6x4 for tray + film packs.

All CM ERGON packers are equipped with an electronic grouping system, manual format changeover and with the “Easy-Load” system to automatically load the cardbord blank magazine.

The blanks magazine capacity can be increased through modular expansion units.

3A corrugated cardboard blank is picked from the blanks magazine by a newly designed picker equipped with vacuum suction cups; it moves along the blank climb and places itself underneath the group of products in transit. The products move on with the short side leading (wrap-around case) or with the long side leading (tray).

4In the tray/case former, the cardboard blank is folded and wrapped around the products by special guides. Then the flap folding devices fold the blank’s side flaps and finally 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.

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.

Continuous motion pack formation

The continuous motion packaging system ensures a fluid production process and protects the containers from strokes, thus granting more reliability, a better quality of the pack and a reduction of mechanical wear.

Thermoplastic material dividing pins

In the pack formation zone, the use of dividing pins made of thermoplastic material, which last longer than those made of metal, reduces the machine noise and protects the fragile containers (such as glass containers) and their labels.

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.

Precise film unwinding with constant tensioning

Film reel with built-in motor, in order to enhance the film unwinding precision thanks to a dedicated brushless motor for each reel. Moreover, a new film-tensioning system, controlled by a piston, ensures a constant tensioning and allows to quickly and easily switch from single lane to dual/triple lane operations.

Precise and automatic film cut

Film-cutting unit equipped with direct drive motorization that allows to easily carry out motor maintenance and reduce maintenance operations.

Perfect cases

SMI 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.

Versatile packs

Besides the cases with traditional sealing, the CM and WP models can realize cases with superposed or joining flaps. As a consequence, the cases can be easily customized with printed images on the 5 visible sides, with obvious advantages for marketing and promotion, as well as better protection of the case content.

"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®.

Easy-Load

Overlapping cardboard sleeve packers

The innovative “Easy-Load” system allows the automatic loading of the cardboard blanks magazine and features considerable advantages from an operating and functional point of view; in fact, the operator can easily load the cardboard blanks, stacked horizontally in uniform groups, because the feeding belt of the cardboard blanks magazine is positioned at the same working height as the packer's infeed belt, rather than under it.

More in detail, the new system patented by SMI is made up of a series of conveyor belts, fitted with motorized rollers, which feed the packer's cardboard blanks magazine; the cardboard blank stacks are carried on these belts up to the area in which they are translated and then continue up to the collection system at case/shrink packer infeed.

Thanks to specific sensors, the layout and feed of the cardboard blanks on the conveyor belts fitted with the motorized roller and their loading into the packer's magazine is, in fact, fully automated.

Therefore, the innovative solution devised by SMI eliminates the disadvantages related to the traditional loading of the cardboard blanks magazine, which force the operator to bend his/her body continuously to place the blanks in the bottom part of the machine.

The technology used in the "Easy-Load" magazine also features the great advantage of ensuring fluid and constant picking operations with a wide range of cardboard blanks having a thickness between 0.5 mm and 5 mm.

TS – Tray stacker

Overlapping cardboard sleeve packers

The NEW TS (Tray Stacker) stacks on two or more layers clusters of plastic, metal , cardboard or glass containers both clustered in cardboard trays or pad and loose (this latter solution solely for fit-in type cans). This device can be installed on SK shrinkwrappers, on WP casepackers and on CM combined packers.

It consists of an electronic stacking device operating in continuous motion, which achieves an output rate up to 60 packs per minute according to the machine model and to the product handled.

Pack collations can vary according to the container shape, capacity and size; in general, the most requested collations are: 4x3 and 6x4. It is available both for single and for double lane production.

After coming out of the trayformer, two or more packs are stacked by means of a Cartesian coordinate system.

Before the pack enters the shrinking tunnel, the film is wrapped around the products and overlapped at the base of the pack.

PID SBP

Overlapping cardboard sleeve packers

The PID SBP® inserts stretched board pre-assembled partitions into cardboard boxes, in order to protect fragile products (such as glass containers) and save their labels from abrasions.

This device can be installed on the WP wrap-around casepackers and on the CM combined packers.

Compared with the traditional inserting systems of non-preassembled partitions, the PID SBP® allows to:

  • reduce the partitions purchasing cost by about 20% and their storage volume by at least 60%;
  • have a more compact machine, since both the partition magazine and the Partition Inserting Device are mounted on top of the machine; in this way, the machine dimensions are the same as those of a conventional casepacker;
  • speed up the partition insertion operation and the loading times of the relevant magazine, since partitions are already pre-assembled;
  • reduce the sensitivity of partitions to humidity and climate changes.

The PID SBP® and the pre-assembled partitions magazine are mounted at the machine inlet, on top of the pack-forming section. The maximum operating speed is 40 packs/minute (1-head model) or 60 packs/minute (2-head model).

A mechanical arm equipped with vacuum suckers picks a stretched board pre-assembled partition from the partition magazine, opens it and lowers it between the products that have just been grouped in the required pack collation.

Finally a cardboard blank is wrapped around the products by means of special guides, thus forming a case.

Easy-Open

Overlapping cardboard sleeve packers

The Easy-Open system can be installed both on the SK shrinkwrappers and on the CM combined packers. It consists of a device piercing the film during the cutting operation, in order to create the required mark.

It can pierce two types of marks, “X”-shaped and “H”-shaped, and is available both for single and double lane production. Thanks to the Easy Open system, the customer’s level of satisfaction is definitely improved, because of the easier opening of the pack.

Moreover, this application does not require any specific packaging materials and, therefore, allows to obtain eye-catching packs without additional costs.

Film welding device by heated blade

Overlapping cardboard sleeve packers

SMI customers can now upgrade their SK and CM packers with an innovative film welding device. The “film welding device by heated blade” joins the edge of the film reel about to end with the beginning of the new reel while the machine is running, with no need to stop production. The machine slows down and the film (printed or neutral with reference mark) is automatically joined; the machine is immediately back to running at full pace.

The new system allows dramatic cuts on energy and maintenance costs compared to traditional hot sealing method, as there are no more sealing rollers to be kept at a consistent temperature. The sealing precision of printed film or neutral film with reference mark is higher, with +/-10mm margin from the reference mark. The "film welding device by heated blade" can handle also no-collant film.
