Arnott Conveyors have developed a product singulator that can be easily integrated to the out feed of spiral chillers / freezers.
With product exiting a spiral in a completely random pattern the singulator will separate and lane via variable belt speeds and guide chicanes, producing a single lane of product.
Should the product be exiting at high level then the single lane can decline via our spiral decline conveyor which uses a tight turn belt, keeping the overall foot print very compact.
The single lane can then be conveyed through the necessary processes through to end of line case packing.
Specifically designed for circular product, the Arnott Laner unit takes delivery of product and diverts them into multiple lanes. This reliable solution is ideal for post oven, freezer / chiller operations where the product needs to be controlled from a completely random pattern into one that can be easily orientated further down the production line.
Examples of post laning applications
Once in lanes, the products can be pitched ready for robotic pick and place operations where a controlled amount of space is required around the product.
The product can be accumulated, counted and slugged, converged into smaller or single lanes ready for flow wrapping or cartoning.
The unit itself depending on the product size can be design to suit any widths. A reject head can also be implemented so Not OK product can be removed from the process before it enters the packing process.
The reject element can be vision or sensor based and look for product errors ranging from colour and shape to the depth of fill in a pie that would be reject at the check weigher stage.
This pre inspection can save on good product being rejected with bad, as well as the carton and packaging utilised further down the line. Rather remove a bad one early than after it has been placed in an acetate, flow wrapped, cartoned and labelled depending on where the quality check operation is on your line.
Disinfection confidence - without chemicals.
Arnott Conveyor’s reputation for reliability throughout the food industry led to them teaming up with Daro UV Systems, the world’s largest ultraviolet disinfection company, to create a complete package solution for maintaining low to high care product transfer barriers and thereby reducing cross-contamination problems.
The system can also be used to treat the conveyor belt as well as the actual product surface, reducing overall contamination. UV lamps are positioned beneath a ladder belt, sides and top of the tunnel.
UV disinfection is a universally proven and industry accepted method of effective reduction of pathogens on surfaces, in water or in air. A typical system can provide as great as 99 - 99.9% reduction of all common bacteria and viruses.
Unlike chemical disinfectants, which rely on chemical oxidation to disrupt the life functions of micro-organisms, UV is simple light energy that cripples the DNA of harmful organisms. By disabling their DNA, the life functions of these organisms are interrupted, rendering them harmless.
Because no chemicals are involved, there are no worries of handling harmful chemicals within the workplace, with their associated by-products and stringent COSHH regulations.
The UV tunnels are available in 3 sizes, 4, 6 or 8 lamp housing system tailored to the size and shape of the product passing through it.
Each system is also designed and fitted with numerous safety features, making it totally safe for use by standard operators after minimal training.
To maintain system integrity, the HMI screen has visual indicators to individually monitor each lamp as healthy, maximum run hours reached and lamp not on.
The concept of an alpine buffer is not new, however the solution Arnott developed to assist their customer as part of their overall line solution, carries benefits to other customers with similar applications.
The main challenge was to handle the product placed into acetates prior to cartoning and keep them flowing in the event of cartoner of other down line issues.
The exit of the pick and place cell in normal operation would convey the filled acetates to the in feed of the cartoner. Should a down issue occur, then the acetates are diverted to the buffer in feed where they are collected until the situation is resolved.
On signal, the buffer will then reverse at a lower speed, re feeding the product back into the cartoner. In this application the cartoner was ramped up to a higher throughput enabling the buffer to be emptied.
This solution can resolve a number of packing area issues whether it involves flow wrapping, cartoning or other in line functions that will at times falter. The buffer allows an amount of time to correct the issue, or prepare for an alternative action should the downstream situation require a longer correction period than the buffer can accommodate.
The Pouch Massager was developed to aid the packing of filled pouches into Shelf Ready Packing cartons, SRP’s. The issue with a product in a filled pouch is that through the process the product in the pouch can become hard or bind together making it difficult to put them into the SRP’s.
The massage unit receives the pouch or bag and manipulates it between the two massage rollers, breaking up and softening the product in side.
On exit from the massager the pouch can be manually or automatically placed in the SRP’s.
The pitching unit was developed to solve the problem at the point of coding or labelling where accumulated / slugged product wants to go through the process in a continual line without appropriate gaps.
The lack of space between the cartons is an issue for a number of process where an individual item needs weighing, metal or X ray detection to ensure quality.
The pitching unit is inverter controlled allowing an accurate control over the product pitching. It also has width adjustment to suit the range of products that may be produced on a single line.
The unit can be fitted to an existing line pending line suitability or simply added into a line as it can be supplied as a standalone unit with its own transfer conveyor. With a standalone unit you have flexible control over the conveyor speed as well as the pitching unit.
