Linears

The linear feeder type SLA ensures a defined and precise interface to bowl and linear feeders or separations. Through a stiff fixation of the linear feeder the SLA shows a steady running behaviour independently from the connected mass of the substructure and therefore, takes no influences from the environment. Lateral oscillation is avoided, resulting in a stable transition with safe feeding, particularly with critical part geometries. The bolt-fixing is completely free of resilient elements and adjusted Drilling holes simplify the adjustment of the liner track junction for an accurate positioning. The spring angle can centralised adjusted without changing the magnet gap.

The RNA linear feeders of these series stand out for the following three characteristics: First, the spring angle has a patented adjustment that maintains the set magnetic gap. Second, the vibratory superstructures are fastened flexibly over a continuous groove (this does not apply to SLL 175).Third, this series has interchangeable vibrating profiles.

Especially the patented adjustment of the spring angles – whilst maintaining the set magnetic gap – is a major advantage of the SLL and SLF series (Pat.no. 4312711-DE). The spring angles are adjustable independent of each other, so that the angle of cast can be adapted to the specific requirements. For example, higher angles of cast with slightly oily or planar parts, or flatter angles of cast with especially sensitive parts. The spring angles are adjustable from the outside. The continuous groove of the vibrating profile enables the vibratory superstructures to be fixed anywhere one wants. The interchangeable vibrating profiles make it possible to increase or diminish the mounting width.

1.) SLL Series

SLL 175

• Patented adjustment of the spring angles whilst maintaining the set magnetic gap.
• Interchangeable vibrating profiles
• Short track lengths of 175–400 mm are possible.

SLL 400

• Patented adjustment of the spring angles whilst maintaining the set magnetic gap
• Flexible fastening of the vibratory superstructures over continuous groove
• Interchangeable vibrating profiles
• Track lengths of 400–1,300 mm are possible
• For higher track weights, one can use additional spring packs and/or magnets.

SLL 800 and SLL 804

• Patented adjustment of the spring angles whilst maintaining the set magnetic gap
• Flexible fastening of the vibratory superstructures over continuous groove
• Interchangeable vibrating profiles, characteristic advantageous features of the SLL series
• Track lengths of 850–3,000 mm are possible
• By using a heavier counterweight and higher installed magnet performance, it is possible to achieve higher track weights with the model 804.

2.) SLF Series

• Patented adjustment of the spring angles whilst maintaining the set magnetic gap
• Flexible fastening of the vibratory superstructures over continuous groove
• Interchangeable vibrating profiles
• Track lengths of 1,100–2,500 mm are possible
• When using these drive units for bulk hoppers, load weights up to 200 kg are possible
• The high magnet performance is especially suitable for mounting sorting hoppers (e.g. in multi-track feeding).

The new linear feeder SLC500 is specially designed for applications with high loads and wide transport and accumulation lines in feeding technology. The new linear feeder SLC500 is ideal for using in applications with wide multi-track transport and accumulation lines as well as with hopper systems in which a high filling volume and filling weight is realised in compact space. The SLC500 has a width of 300mm and a length of 500mm plus a load capacity of up to 70kg. [Details]

RNA linear feeders of the GL series have horizontally built in springs. Their feeding performance resembles a “sliding” rather than the “throwing” typical of linear feeders. Because of the small relative motion between the preceding and following device, this feature is most advantageous particularly at interface transitions for small component parts.

RNA linear feeders of the SLK series have the following product features:

• Compact, small devices
• Simple handling when changing the springs
• Short track lengths of 200–350 mm are possible with the SLK 05.

The linear feeders of the SLS series are suitable for parts with high-precision guiding at the transition to separation or to the vibratory bowl feeder (rotary feeder). Thanks to the counter-vibration principle of this linear feeder, the vibrating forces in the base plate are almost balanced.

Product features:

• Compensation of the vibrating forces in the drive unit
• No vibrations are transferred to the substructure
• No reciprocal influence between several combined devices
• No influence on other devices and processes even in the immediate Surroundings
• Highest precision at the interfaces
• An adjustable fixing makes it unnecessary to set the transfer points during maintenance.

Besides the complete product range for linear feeders available on stock for the series GL, SLK, SLS, SLA, SLL and SLF, special models and accessories are available upon request.
