Allocator: Increased quality

Allocators are integral parts of inline-sorting, above all, in bottling plants and the food and drink industry. Due to the high production speed, modern systems work with powerful control systems, highly dynamic drive technology and precise industrial image processing. We have developed our own Allocator based on our comprehensive know-how of the container glass manufacturing process. This combines image processing, SPS and servo-motor drive technology into a compact and easy to integrate unit. The function principle is, in essence, based on a rotary, eccentric allocation wheel, that can transport bottles, as an example, independent of their load and with a smooth movement, to a parallel conveyor track. An industrial image processor, such as our separator, determines, according to a predefined analysis framework, which container is to be transferred. This can be dependent on quality characteristics such as label position, bottle colour, or closure position.In its Allocator, Bertram is deliberately passing on the any of the usual pneumatic solutions. As the rotary servo-method works considerably faster, wear-free and due to the fact that it goes without expensive compressed air, far more energy efficient.

The Separator allows bottles and/or jars to be distributed between up to four tracks without changing the production speed. With its fast industrial image processing in combination with the corresponding SPS-programming, Bertram’s system works so flexibly that it can handle all standard tasks. Resulting, in essence, from the shape and number of bottles and/ or jars, and their allocation to the correct tracks.
Bertram’s bottle separator consists of a powerful industrial image processor, that is controlled by a pre-programmed, ready to use IPC-control system and a servomotor driven Allocator. Individual adjustments to the respective applications can be made directly on the module, either through an integrated touch screen, a USB connection with an external keyboard, or, the most convenient, remotely from your PC. We use forward-looking technology based on real-time ethernet, in the form of Profinet-communication at the input/ output level.

Bertram combines precise and highly dynamic servo drive technology with quick industrial image processing. Using this, we have developed a machine that orientates bottles and jars with extreme accuracy. The in-line ‘Orientator with a recognition system’ can turn up to 500 containers per minute into a desired position. The belt Orientator (or belt orienter), which holds the Lower Saxony Handwork Innovation prize, efficiently and smoothly turns containers to the desired position for the following production step. Palletising, filling, capping or labelling machines can then work considerably faster. In summary, productivity increases, if nothing else, through the skillful exploitation of industrial image processing.

About us

Company portrait

Production systems can only work efficiently and reliably if all mechanical and electrical processes in the control engineering concept are coordinated. From machine orientated measurement and control engineering to production management and control systems: Bertram Elektrotechnik works continuously and modularly with both SPS-Programming and a choice of hardware elements while always using the newest technology. In doing this, our biggest trump card is our flexibility to always adjust to our customers wishes. This is how Bertram offers its business partners everything from one source: from analysis and project planning, to production, montage and start-up, and to after sales service. At the same time it refers back to standard products from leading manufacturers wherever it is possible and practical - for example, in the areas of automation solutions and industrial image processing.
The goal for Bertram specialists is to make reliable, efficient and easily understandable systems, and they are highly motivated, no matter the size of the automation task. Whether it concerns the control of single machines or automatising whole industrial systems, our maxime is: to always find the optimal solution for each respective application - this is not only valid for hardware project planning and SPS-programming, but also for designing industrial image processing.
Economical wiring needs in large systems are met, due to intelligent sensors and actuators with a direct fieldbus connection and the decentralised nature of the automatisation solutions, ensure the necessary flexibility for the expansion and adaptation. Decentralised control engineering, which is coupled with the industrial network, accelerates the rate of data exchange between superior control and monitoring stations and enables the integration into process management systems, in which all information converges. Even for initially small solutions, there are many possibilities to integrate them later into the whole concept with a company wide production planning system. Isolated solutions are therefore avoided and the investment is secure for the long term.
