Components

The RNA linear feeders in these series are distinguished by three characteristic features: Firstly, by a patented adjustment of the spring angles, in which the set magnetic gap is maintained. Secondly, the oscillating superstructures are flexibly attached via a continuous groove (does not apply to SLL 175). Thirdly, this series has mutually exchangeable vibrating profiles. In particular, the patented adjustment of the spring angles - while maintaining the set magnetic gap - is a significant advantage of the SLL and SLF series (Pat. no.: 4312711-EN). The spring angles can be adjusted externally and separately to meet special requirements e.g. a higher projection angle for slightly oily components or a low angle for thin parts. The spring angles are adjustable from the outside. The continuous groove of the vibrating profile allows the toolings to be attached at any point. The interchangeable vibrating profiles can be used to increase or decrease the mounting width.

SLL series

SLL 175

• patented adjustment of the spring angles while maintaining the set magnetic gap,
• interchangeable vibrating profiles,
• short track lengths of 175-400 mm can be realised.

SLL 400

• patented adjustment of the spring angles while maintaining the set magnetic gap,
• flexible fastening of the toolings via continuous groove,
• interchangeable vibrating profiles,
• track lengths of 400-1,300 mm can be realised,

• flexible fastening of the toolings via continuous groove,
• interchangeable vibrating profiles, characteristic advantage features of the SLL series
• track lengths of 800-3,000 mm can be realised,
• due to the use of a heavier counterweight and a higher installed magnetic power, higher weight toolings are possible with type 804.

SLF series

• patented adjustment of the spring angles while maintaining the set magnetic gap,
• flexible fastening of the toolings via continuous groove,
• interchangeable vibrating profiles,
• track lengths of 1,000-3,000 mm can be realised,
• when used to drive bulk hoppers, useful weights of up to 200 kg are possible,
• because of the high magnetic power, particularly suitable for holding sorting trays (e.g. for multi-track feeders).

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 workpiece geometries. The bolt-fixing is completely free of resilient elements. Adjusted drilling holes simplify the adjustment of the linear track junction for an accurate positioning.

The new SLC500 linear feeder offers its optimal use in applications with wide multi-track feeding and accumulating tracks, but also in the realisation of hopper systems in which a high filling volume and filling weight are realised in a compact installation space. The SLC500 has a width of 300 mm and a length of 500 mm and has a high load weight of up to 70 kg.

The SLC is particularly suitable for the upright transport of elongated vials, as used in the pharmaceutical industry, for example, where vials have to be transported gliding on a fixed vibrating plate. During the development of the SLC500, special emphasis was placed on incorporating the proven and patented features of the SLL linear feeders. These features enable simple and logical adjustment of the drive with regard to speed and running characteristics of the workpieces (e.g. speed increase on the discharge side) and smooth and accurate running behaviour.

The linear feeders in the SLS series are suitable for parts with high-precision guides at the transition to the separating or vibratory feeder (bowl feeder). With this linear feeder, the oscillating forces are almost balanced due to the counter-swing principle in the base plate.

Product features:

• compensation of the vibration forces in the drive unit.
• no transmission of vibrations to the stand
• no reciprocal influence of several combined units
• no influence on other units and processes, even in the immediate vicinity
• highest precision at the interfaces
• no adjustment of the transitions during maintenance work due to adjustable fixation

The linear feeders of the PARU Mini series are available in two sizes: PARU Mini XS and PARU Mini S. They are suitable for parts with high-precision guides at the transition to the separating or vibratory feeders (bowl feeder). With this linear feeder, the oscillating forces are almost balanced due to the counter-swing principle in the base plate. The PARU Mini series is fully digitalised. Every conventional process step is completed with just a few clicks in the digital world. I.e. the drives can be digitally tuned and simulated with the Digital Motion simulation software. This enables the user to digitally balance the linear drive, set the natural frequency, determine the throw angle or adjust the leaf springs. This offers the possibility to adjust the drive to the customer's own feeding system already before receipt.

RNA linear feeders in the GL series have horizontally installed springs. Their conveying behaviour is more like "gliding" than the "throwing" typical of linear feeders. Especially at interface transitions for small workpieces, this characteristic is of great advantage due to the low relative movement between upstream and downstream equipment.

The RNA linear feeders in the SLK series are suitable for driving vibrating chutes into which the bulk material is transported. These are used for the linear transport and correct position feeding of mass parts as well as the metered feeding of the bulk material.

Product features:

• compact, small units
• easy handling when changing springs
• short track lengths of 200-350 mm can be realised with the SLK 05

The BV8-BV200 vibration hoppers are based on the proven linear drives of the SLL and SLF series. They are particularly suitable for storing small and medium-sized workpieces (BV8-BV60) and are used, for example, within a feeding system for filling vibratory feeders (bowl feeders). Vibration hoppers are characterised by a closed chute into which no thin-walled workpieces or chips (for example through joints) can penetrate. The BV100-BV200 types are not only used for high feed performance and the associated demand for high filling volumes. They are particularly suitable when larger and/or heavier workpieces have to be fed. In addition, pre-separation of the hopper material is possible by accelerating the transport speed towards the outlet. In this way, downstream equipment can be loaded more accurately.

Type BVL

• filling volume up to 50 l,
• hopper chute made of stainless steel,
• very good conveying behaviour (vibration transmission),
• flexible adjustment options (based on the proven linear feeders of the SLL series),
• workpieces are pre-sorted with increasing speed towards the discharge,

Our belt hoppers are suitable for storing workpieces and are based on the conveyors of the FK/FP 120 series.

The main features:

• filling volume from 5 to 200 l,
• hopper and chute made of stainless steel (brushed on the outside),
• belt in FDA design,
• adjustable sealing strips made of stainless steel,
• lock curtain,
• motor in three-phase design.

The belt body of the FK120 is made of sheet steel, that of the FP120 of aluminium profile. Stainless steel systems and different types of belts are also available.

RNA mini-band conveyors type FP15 E and FP15D are manufactured from aluminium profiles and are especially suitable in small confined spaces.

The knife edge construction makes it possible to overcome potential problems at critical transfer points. The belt body consists of an aluminium profile that allows for flexible mounting options such as stands, side guides and the like. The FP15 D is a twin-band conveyor used to transport hanging parts. A benefit of this unit is that the installation of escapements between conveyors is made easier (e.g. extraction station).

RNA STF incline feeders: the solution for "highest" requirements. RNA offers a wide product range of hopper systems when workpieces are to be stored and safely transferred to downstream processes. Our incline feeders are particularly ergonomic and suitable for especially high filling volumes. These hoppers are always used when stored workpieces are to be ergonomically fed to a downstream process. The incline feeders are ergonomically designed so that filling by the machine operator takes place at the lowest possible height and the downstream processes are supplied in a compact, dosed and gentle manner. The incline feeders are based on our proven FP120 series conveyors and are individually designed to suit your task.

In addition, we also offer our popular and proven mini incline feeder, which is particularly suitable for the smallest installation spaces. The mini incline feeders in the STF series are always used when workpieces are to be stored in the smallest installation space or when rejected workpieces from the sorting stations are to be returned to the feeding process. In combination with upstream vibratory hoppers, workpieces can also be transferred to the downstream process in a gentle and optimally dosed manner. These incline feeders are designed for direct mounting on the machine table.

Special features are:

• all components in contact with the product are made of stainless steel
• specially manufactured "hopper sump" to avoid workpiece jamming with cleated belts
• simple and compact design, cost-effective
• ideal for applications with incline feeders in narrow installation spaces

The new generation of RNA inclined hoppers is another variant of the standard BUS series, which is currently available in sizes of 25 litres and 50 litres. The compactly built BUS25 and BUS50 inclined hoppers are designed for direct mounting on the machine table. The adjustable inclined position of the hopper enables a significantly lower filling height than is the case with normal horizontal hoppers. The hopper is driven by a direct drive. The toolings are made of brushed stainless steel and all weld seams are appropriately through-welded and cleaned.

When developing these compact inclined hoppers, we also took into account the easy installation of accessories. This means that these hoppers can easily be equipped with covers, quick emptying devices or cleated belts.

We have completely revised our step feeders. The new generation of RNA step feeders in the STS series are available in 2 different sizes. A stationary hopper is integrated in each size. The low filling height allows manual filling. As the basic unit in the parts feeding system, the step feeder is built in such a way that the associated stationary hopper can be filled by hand due to its low filling height. The size of the hopper can be adjusted according to the workpieces. The workpieces are conveyed upwards from the hopper sump by means of counter-rotating lifting plates and thus reach the desired transfer height without the need for any further conveyor technology. The workpieces are already pre-sorted by the upward transport and the shape of the lifting plates. In addition, the lifting plates can be equipped with clamping protection if required.

The step feeder operates almost noiselessly and vibration-free without workpieces. With a range of linear feeders matched to the STS series, RNA offers a powerful overall concept for specific tasks in feeding technology, from linear feeders to conveyors. High performances even with the smallest sorting features characterise this range.

Control units of the EBF 05 type series are microprocessor-controlled devices for adjusting the running speed on RNA belt drives, incline feeders and apron feeders. Two types with 0.37 kW and 0.75 kW are available for power adjustment

The units generate a three-phase mains with adjustable frequency from the single-phase mains 230 V, 50 or 60 Hz. The speed of asynchronous squirrel-cage motors operated with this mains supply is infinitely variable, ranging from 17 Hz to 85 Hz. The lower limit results from the minimum speed necessary for self-cooling, the upper limit is set by the maximum permissible speed of the bearings.

A release input for starting and stopping the drive without power, as well as a signal output for fault detection are routed to the terminal strip and are available to the user by means of additional wiring.

The new SCU1000 (mains connection fixed via cable) and SCU2000 (mains connection can be plugged in) control units from RNA have been fundamentally revised and replace the previous ESG1000 and ESG2000 series. They are characterised by an innovative design that allows easy operation and integration into modern systems. A clearly arranged display ensures simple and safe operation, and the plug connections placed on the front allow several control units to be directly connected side by side. The use of the latest processor and communication technology leads to optimal operation of the control units.

General features and functions:

The compactly designed control unit can supply all RNA vibratory drives up to a load current of 6 amps and is intended for individual installation directly on the vibratory drive. The conveying speed can be precisely adjusted within the setting range via LED display and is matched to RNA drives. Thanks to a new type of control, the conveying speed is kept largely constant even when the mains voltage fluctuates. The illuminated rocker switch in the front panel disconnects the control unit from the mains with two poles. For frequent switching or operation with a higher-level control system, it is possible to switch off the power without using a potential-free contact or a 16-30 VDC voltage signal. Furthermore, the operating status of the control can be queried via a "READY" or "ACTIVE" signal. The unit can be used in both 230 V and 110 V networks, the network selection is made via an internal switch. All other settings of the unit are carried out via the integrated LED display.

The frequency controller units of the ESR 3000 series are suitable for operating one bowl or linear feeder and for connecting two sensors to monitor and control the material flow. The oscillation frequency can be manually adjusted (e.g. when using alternating bowl feeders with different load weights).

Equipment:

• one power output for bowl or linear feeder,
• automatic adjustment of the oscillation frequency after calibration, i.e. fine mechanical tuning (spring mounting) is no longer necessary,
• automatic switchover to 230 V or 110 V mains voltage,
• membrane keypad for setting and changing the operating values in the setting menus,
• simple menu navigation for changing the setting parameters,
• manual adjustment of the transient response by changing the time constants,
• external control 24 VDC,
• a relay output and an opto-coupler for status messages and other links,
• unit messages:
  • Active = unit running,
• possibility of connecting external devices, e.g. solenoid valve,
• connection of one sensor (supply voltage 24 VDC 10 mA)

Highest efficiency and cost-effective! The spring untangler is designed to separate intertwined springs so that the individual springs can be used in the further process or dosed for the next device. The spring untangler is often used together with a vibrating conveyor or hopper for storage, which feeds the springs to the spring untangler, which then feeds the separated springs to another vibrating feeder for sorting and processes for further processing.

• For small to medium-size springs
• High reliability and untangling quota
• Integrable between hopper and bowl feeder or between two bowl feeders (for storage and sorting)
• Housing made of stainless steel
• External on/off switch with additional fuse
