Bag Filling Units

Automatic filling and closing lines for use of tube-on-a-reel (FFS)
This machine was designed to attach manufactured bags through a specially designed system and contains the following properties:

• A combination machine consisting of a Rodomatic sack making and sack placing system for manufacturing roll-off bags. A sack hanging machine is integrated for processing ready-made open mouth manufactured bags.
• Without mechanical switchovers, we can switch between tube-on-a-reel and manufactured bags.

Automatic filling and closing line for the use of open mouth bags
Designed for attaching manufactured bags:

• Suitable for all types of bags such as paper, plastic, polypropylene, etc.
• Suitable for bags with or without a side fold.
• EeEasy setting for various bag sizes (through hand wheels or electronically).
• Bag stacker in several versions.
• Bags can be folded and closed through gluing, sealing, sewing or a combination (optionally finished with crêpe top border).

Combined automatic filling and closing line (tube-on-a-reel and open mouth bags)
A combination machine consisting of a Rodomatic bag making and a fixing device for making bags directly from the roll, with an integrated bag attachment machine for processing manufactured open mouth bags.
Without mechanical switching, we can switch between tube-on-a-reel and manufactured bags.

Bag Vacuumisers

Vacuum packing setup

A major challenge is packaging products with a large amount of air. Until now, Arodo is the only machine manufacturer in the world that is able to vacuum bag these products (including cement, etc.). This system is also frequently used to vacuum pack bag products for which a long shelf life needs to be guaranteed (milk powder, etc.). This system is known under the name of AROVAC. The system’s advantages are:

• No (micro)perforation required in the bag.
• Suitable for unprotected storage in the open air (water and weather resistant).
• No influence of dust and oxygen on your product, which further improves its shelf life.
• Pure bags, no dust or unpleasant odours.

Fully automatic FIBC filling system

Fully automatic FIBC filling unit with empty pallet magazine and automatic pallet discharge conveyor.

Arodo manufacture different types of big-bag filling systems. Think of mobile systems which can be added to a sack filling system where big bags are filled according to the “multi-dump” principle. Also filling systems with an own dosing and weighing device are part of the delivery program.

Palletisers

Palletising machines
Arodo fully designs and produces palletising machines. Because of this, Arodo is able to meet customer-specific requirements and thus offers a suitable solution to any palletising wishes. Naturally, to save expenses, as many of our tried and tested techniques are used. The assortment of Arodo palletisers consists of four types: the DS, the GR, the GRS and the robot palletiser. After analysis of the customer’s situation, one of these types is suggested in consultation.

DS
The DS palletiser slides the bags in a desired pattern on the lay table. By opening the lay table, a complete layer of bags always ends up on the constantly dropping pallet until loading height has been reached.

• High capacity up to 2,500 bags/hour
• Well filled bags
• Non overlapping stacking

The bottom pallet in the empty pallet magazine is freed with a fork mechanism because of which it is brought to the loading position with a roller conveyor without the danger of empty pallets getting stuck in the magazine. The DS palletiser stacks the pallet layer per layer. The supplied bags are oriented in the right direction with a turning knob. The rows of bags this creates are brought to the lay table with a sliding mechanism. The operating system also enables positioning the bags at a mutual distance from each other without mechanical stops. This results in greater flexibility of bag and pallet sizes. The empty pallet is brought to just below the lay tables with the pallet lift. By opening the lay table the formed layer ends up on the pallet. When opening, the layer is locked in on four sides, resulting in a well-stacked pallet. Every deposited layer is pressed against the bottom of the lay table to ensure greater pallet stability by smoothing the layers and pressing air out of the bags. This cycle repeats itself until the desired loading height is reached. This way, we can reach a maximum capacity of 2,500 bags/hour. The loaded pallet is removed from the palletiser with a roll-out track.

Operation of the palletiser can be programmed according to your wishes. Stacking pattern, pallet measurements, as well as pressing force and loaded pallet height can be filed in the machine’s memory per bag size. As the build-up is always modular we can place a palletiser in almost each space.


GR
The GR palletiser combines the functions of a conventional palletiser with those of a robot. Via a roller conveyor the bottom pallet is transported from the empty pallet magazine to the loading position in the palletiser. The stack of empty pallets is lifted with a fork-lift mechanism so the pallet to be moved is prevented from getting stuck. The bags are put onto the pallet layer per layer. A rotating gripper picks up the bag and lets it drop from a limited height onto the right place on the lay table while also being correctly oriented. This also enables the processing of poorly filled bags or even unstable bags and also offers the possibility of stacking the bags overlapping. This makes this palletiser extremely flexible with regard to bag and pallet sizes. After forming a complete layer, the lay table opens and the layer ends up on the pallet that was taken to just under the lay table by the pallet lift. When opening, the layer is pressed down sideways to obtain a neatly stacked pallet. In order to smooth the top of each layer, each layer is pressed down against the underside of the lay tables. This creates an extremely stable pallet because the air is also pressed out of the bags. When the required loading height has been reached, the pallet is transported with a roll-out track.

Pallets can be stacked with a capacity of up to 1,200 bags/hour. Operating enables the palletiser to be programmed freely with the possibility of filing pallet dimension, pressing force and loading height per bag size. As the build-up is always modular we can place a palletiser in almost each space.


Robotpalletiser
A robot palletiser consists of an acquired robot with a self-developed gripper or suction button. It picks up the bag and places it directly on the pallet in the desired pattern. The robot takes a pallet and puts it on the ground or on a table. It then starts stacking. It can also take a sheet of paper or plastic and place it on the pallet or stack.

The robot is operated via customer-specific Arodo operational software that guarantees easy operation. We recommend using a robot when products need to be picked up from several points and/or several different products need to be stacked on various pallets at the same time. For instance, other products such as boxes and buckets can also be stacked on the same line.

Stretchhooders

Stretch hood machines

ARODO’s stretch hood machine was specially developed to load pallets with bags or FIBCs. The machine is, however, also extremely suitable for covering pallets with boxes, barrels, stones, etc.

Optimum protection
The cover is completely waterproof and provides optimum protection against all types of weather, as well as dust. Furthermore, no heating is required for watertight pallet packaging and the pallet’s stability is optimal. Finally, for commercial purposes the company logo can be depicted on the cover.

Working safely
Many systems on the market provide solutions where the cover is constructed on top of the machine. The disadvantage of this is that, in case of interruptions and for maintenance, work is required at a (great) height, which involves risks for employees. Arodo on the other hand has developed a system where the cover is made on shop floor level. Arodo likes to help think along about safety!
