Description

Rosler R 425/4600 DA Continuous Vibratory Linear System 

Continuous flow deburring 

The Rosler R 425/4600 DA Vibratory Linear Bowl is for the surface finishing of mass parts in a continuous flow, offering many advantages over the more conventional batch finishing processing:

"R" vibrators consist of a trough-type, rectangular work bowl . They are especially used for

• processing of robust mass produced parts of small and medium size (stampings, die-castings, etc.)
• deburring and grinding of mid- and large-size components (engine and pump housings, oil pans, cylinder head covers...)

Installation includes:-

R 360/3000 FB/T Discharging Belt 1

R 360/2500 FB/T Discharging Belt 2

RT 550 Euro Rotary Drier

Advantages

Continuous surface finishing with a continuous flow of parts offers many advantages compared to batch processing:

• Easy integration of the surface finishing process into continuous manufacturing systems
• Easy, cost-effective automation of the surface finishing process
• Lower cost for material handling, because the parts do not have to be collected in batches

specially designed for continuous processing in one cycle by feeding the workpieces in loading cycles. These machines are particularly suitable for removing slight burrs as well as degreasing oily parts with very short processing times. 

The process ...

Components are fed continuously or in batches into a U-shaped semi-round processing chamber filled with polishing and deburring media (chips) and are rolled over for a certain time to achieve the desired surface finish.

The processing parameters such as the processing time and the desired polishing, deburring or burnishing effects can be adjusted by adapting the processing chamber inclination, the mass balance and the number of revolutions.

After the single run through the processing chamber the chips and components are separated in the separation station. At the same time the components can be rinsed down and sent on for any follow-up processing.

The chips will be fed back by means of a conveyor belt transport system for continued use in the processing chamber. 

Range of applications ...

deburring, finishing, radiusing, polishing or ball burnishing of punched, diecast, forged or cut metal components using the powerful Linear-Flow installation technology. High throughput capacity, enormous profitability and the vast potential for automation fascinate ever more users.

The  Linear-Flow-System, in detail

The processing chamber is the core of every continuous flow installation. In the LINEAR-FLOW continuous flow installation, the processing chamber has an optimum shape as far as flow and processing technology are concerned and everything matches exactly. In this way an efficient processing of components and a perfect result is guaranteed.

Technology, that inspires .

The special shape of the inner surface of the processing chamber is the result of intensive developmental efforts. 
The one-sided and rounded U-shape guarantees an optimal rotation of media and components. This increases the process efficiency and components do not get stuck to the lining of the processing chamber nor do they drift to the surface.

Long lasting wear resistant lining

Highly wear-resistant special LF-polyurethane
Spreading of the processing water over the whole length of the processing chamber for constant 
component treatment at maximum cleanliness.
Large area, easy to change (multiple) bottom effluent sieves at the lowest point of the processing chamber 
guarantee a constant renewal of the processing water.

Robust drive technology ...

The special Rösler electrical drive motor and the vibration units, which are intercoupled in line, are the building blocks of the powerful, well proven drive concept. Energy loss through transmissions is avoided by means of the direct flange connection of the vibration units to the processing chamber.

 The installation of the units in line along the length of the processing chamber guarantees a constant working motion and a high working efficiency.  

As a result of the optimal accessibility it is always easily possible to make adjustments to the vibration units in order to adapt the system to new processing tasks.

The exterior of the processing chamber ...

The processing chamber is of torsion-proof and vibration-proof welded stainless steel construction. The finely spaced external ribs and the thermal glowing process provide for a stable and low-tension construction.

Waste water

specially designed for continuous processing in one cycle by feeding the workpieces in loading cycles. These machines are particularly suitable for removing slight burrs as well as degreasing oily parts with very short processing times. The waste water drainage pipes are fed into a maintenance friendly collecting trough – located on the outside of the installation.

Vibration

Active vibration dampening with the aid of the air-suspension system effectively prevents the transfer of vibrations to the installation foundation.

Efficiency

The many special features of the Rösler Linear-Flow installations repeatedly draw the attention of the users. Highly flexible installation technology is more in demand than ever before.

Technology..

The special inclination technology of the processing chamber allows for the most individual adaptability that a
linear flow installation could possibly offer from the flexible adjustment of the processing speed to the batchwise processing of highly sensitive components.

The programmable processing speed of linear flow installations ...

Sensors monitor the variable inclination position of the processing chamber. Individually adjustable processing
times can be set at the control panel.

XXL processing performance ..

The special separation area can be adapted in a flexible way to the maximum weights and sizes of the components. As a result, even components with a diameter of up to 550 mm or a weight of up to approx. 50 kilos can be processed without any problem.

Exact, flexible and fast ...

The separation station, which is independent from the processing chamber, has its own adjustable vibration drive motors.

In this way you can guarantee an optimal separation in any application scenario without any influence on the processing intensity during continuous or batch production.

Separation process by the large area separation screen decks programmable through the control panel. 

Seamless inner coating consisting of noise absorbing, corrosion-proof polyurethane.

Turning steps with various standard heights for extraction of media from “cup shaped” components.

Quick change separation screens – no tools required – allows for a flexible adaptation to any separation requirement.

The sensitivity of the components determines the intensity and the speed of the separation process and is infinitely variable.

Integrated component-rinsing installation.

Convincing flexibility

An effective media transportation system is the basis for the optimal installation performance and tailor-made individual utilisation. After the separation of the media and the components in the large separation area, the media are fed into the lateral vibration-driven transport trough.

Water residues and component fillings are removed with the aid of the media classification screen area. A wide conveyor belt with thick edges and scoop elements transports the chips back.

Moisture residues are collected over the whole surface and fed into the collection basin. 

The media land in another vibration-driven transport trough and are fed back to the processing chamber. All cross-over points have a minimal drop height and are therefore suitable for ceramic polishing media

Parts feeding system

The feeding of components into a linear flow installation can be achieved in several ways. There are tipping devices designed for the discharge of components from transport containers. The combination of a buffer trough controlled by batch weighing allows for a measured feeding of bulk components. Conveyor belts or roller tracks with continuous of intermittent running can also be implemented. Currently fitted with conveyor belt loading. 

Post treatments

A continuous output of components from the linear flow installation is ideally suited for automatic follow-up treatment. Various washing, conservation and drying devices can be implemented.

Automatic storage and transport systems as well as container-filling devices for the processed components can be linked up in various ways. Currently supplied with a hot air recirculating drying tunnel.
