Pet food bagging machine
Pet food bagging machine
Thanks to their 30 years of experience in the pet food sector, Concetti manufacture innovative pet food bagging machines that offer flexibility and increased outputs, featuring many patented devices that allow an unprecedentedly accurate handling and sealing of the most advanced PE, PET and PE-Alu-PE gusseted bags demanded by pet food marketing departments. Moreover, Concetti pet food bagging machine now features an innovative device for inserting and sealing a pre-formed zipper onto the top of an ordinary PE bag.
Weighers machine for Pet Food
Concetti produces its own range of pet food weighers in-house. High accuracy is obtained by a combination bagging machine for pet food comprising a belt for the main feed and a vibrating trough for fine feed to add precisely the right quantity of kibbles. The weighing ranges vary between 1 to 7 kg and 2 to 20 kg. With two weighers working in parallel, the output rate reaches up to 1800 bags/hour.
The Concetti range of pet food bagging machines
All Concetti bagging filling and closing machines are monobloc structures that constitute an integrated unit for safe, clean and reliable packing. Let us focus for example on the IMF pet food bagging machine for pre-formed bags. This filler features two discharge spouts and two empty bag magazines to ensure an output of up to 1800 bags/hour. Users benefit from the most flexible bagging system available on the market. The IMF is designed to run all bag formats from 1 kg right through to 20 kg, both gusseted or flat bags, while the bag material can be coated paper or PE, PET, aluminated PE, etc. Moreover, bags with carrying handles, bags with lateral carrying handle, with easy-peel and front or top zipper, hooded bags, stand-up pouches, single-lip bags, bags with Quattro-seal or Stabilo-seal - all these innovations can be worked with Concetti’s IMF.
This flexibility is not limited to the IMF but is common to all Concetti pet food machine. Many of the features described apply equally to the IGF and the IPF machines for both large and small format bags.
How the filling operation works in pet food bagging machines
The actual filling operation is one to which Concetti have dedicated special attention. Opening a gusseted bag for filling requires care to ensure the shape is not lost and the gussets are properly reformed. Concetti pet food bagging machine is equipped with special devices for holding and restoring gussets of bags with different sizes and formats. In addition, it also comes with patented systems for quad seal or stabilo bags. These bags have vertical seals on the four lengthwise edges to improve stability and appearance on the shelf but are difficult to handle automatically and hard to realign precisely when closing. Without Concetti’s patented system, arranged to give all-round gripping of the bag, proper opening and realigning of the quad seal bags is simply left to chance.
Efficient filling on Concetti equipment includes bottom vibration of the bag for compacting the product to improve palletization and reduce the bag length. Further, after the bag mouth is realigned and closed and during transfer to the sealing station, Concetti uses a mechanical device (a roller) that can be selected if necessary to evacuate any excess air in the top of the bag.
Heat-sealing of PE bags is a science in itself. The IPF, IGF and IMF all designed by Concetti allow the bag to be closed at different heights on the bag face. For example, the seal can be exactly at the top edge, below the carrying handle or many centimeters below the top edge. It is also possible to have two sealing lines on the same bag, where the distance between the two seals is set by program according to the bag features, one seal at the top edge and a second one below the carrying handle. Furthermore, the sealing line itself can vary in height from 4 to 20 mm.
To guarantee a flawless seal, Concetti have opted for an in-built sealing system using high quality, heavy-duty components. For high performance and long periods without operator attention, the sealing bars are protected by a reel mounted Teflon sheet allowing a clean sealing face to be wound on whenever signs of wear appear. On high-speed applications a seal-cooling device is supplied.
Pet food bagging equipment from a tubolar reel
The series of form, fill seal pet food machines encompasses many of the technical features highlighted so far, while offering one additional advantage: cost-effectiveness. Today, the market offers tubular reels fabricated from various materials, ensuring the best protection for the product. And reel graphics can be extremely attractive. But still, the tubular reel stock represents the lowest cost way to create a strong and safe bag.
Bagging equipment for Pet Food industry
Concetti manufacture a complete range of palletizing machines from single column pick and place robots to low and high-level layer machines. But for maximum flexibility in pet food applications the four-column palletizer is the preferred solution.
The gripper tool takes one or two bags at a time from the roller conveyor and places it on the stripper plate, at a point assigned by the program. The bags can easily be overlapped partially along the top or the side if required. The layer can be arranged in any convenient pattern regardless of the bags shape or how full they are. Once a layer has been completed, it is compacted on all four sides and the stripper plates open to unload the layer onto the pallet below.
Because Concetti specializes in complete including weighing, bagging, palletizing, metal detectors, checkweighers for pet food, it is easy to link these separate devices to form one integrated system so the program for the complete line is changed at one location without the use of tools. This makes the operator’s job easier with less risk of set up errors, reduces the changeover time and increases productivity. Pet food producers with many different products, bag weights, sizes and short job runs will find this very appealing.
