Buhrs 4000

This innovative, high quality poly and paper wrapping system is not just more flexible and safer, it is also characterised by its reduced set-up and maintenance times. As a result of this the system offers more productivity than any other system currently available. The Buhrs 4000: offering the ultimate design to help you make more money in the mailing industry.

Buhrs 4000 – Principle of the system

Owing to the modularity of the Buhrs 4000, the system can be configured ideally for co-mailing. It has a low gathering section, automatic feeder synchronisation and individually controlled feeders via the new Buhrs System Controller.

Buhrs 4000 – Benefits

Selectivity, increased product variations and job complexity are today's major issues in the mailing industry. In addition price pressures and shorter production times to run jobs are common occurrences.

Buhrs 4000 – Flexibility

Your ability to handle increasing job variations and to respond to last-minute changes in job configuration strongly depends on the flexibility of your equipment. The possibility of quickly optimising the machine configuration for specific jobs enables you to obtain short production times. Easy variable positioning of feeders and page openers improves the quality of inserting. The Buhrs 4000 offers you the competitive advantage to anticipate your customer's needs of tomorrow and increases your business today.

The flexibility of the Buhrs 4000 results from the following properties:

The mobile feeders are interchangeable between systems
Feeder type, position & orientation can be changed in less than 2 minutes
Opener position can be changed in less than 2 minutes
Simple switch from paper to poly wrapping within 20 minutes
Modularity for easy future system expansion
Easy integration with equipment both upstream and downstream

Buhrs 4000 – Reduced set-up times

Set-up times strongly influence your ability to handle an increasing number of different jobs. The increase of automatic regulated functions and decrease in the number of mechanical parts contributes to reducing the number and length of set-up procedures. System adjusting is tool-less and trial and error cycles are unnecessary. It is even possible to set up feeders off-line.

Buhrs 4000 – Increased productivity

Increased reliability of the system contributes to reducing downtime of the machine.
The system, designed for an optimal number of operators, is user-friendly. This aspect of the machine shortens the learning curve for operators and increases their satisfaction. Quick reset and restart, after system stops, simplifies the handling of difficult products without effecting the net output. Result: your system is more productive!

Buhrs 4000 – Reduced maintenance times

Fewer parts and the use of servo technology reduce maintenance times. This in turn decreases the downtime of the equipment and minimises system maintenance costs. The following parts of the system ensure reduced system maintenance:

Timing belts reduce lubrication and chain tensioning procedures
Off-line maintenance of feeders allows autonomous production schedule
Quick default diagnosis provides clear reporting of faults in MMI and feeders for preventive maintenance (see photograph)
Use of servo motor reduces need for spare parts

Buhrs 4000 – Safety and ergonomics

Safety and ergonomic regulations are becoming increasingly obligatory. Safe ergonomic systems, like the Buhrs 4000, enable you to comply with safety regulations without limiting your net system output. Improved operator confidence results from prevention of injuries.

System characteristics that make the Buhrs 4000 safe and ergonomic:

Automated push-button adjustments lead to short set-up times
Safety chain lug mechanism with optional detection
Clear and easy access to Man Machine Interface (MMI) and control panels
Lowered gathering section reduces body stress
Mobile RF5 feeders with optional in-line nose extension for accurate placement
Direct servo drive motors on the sealing knife to reduce number of parts
Lowered noise level from the use of timing belts and absence of a control drive shaft
Start-up audio and light signals
