2. Safety directives

We have taken great care in design and manufacture of our vibratory feeder in order to ensure smooth and safe operation. You, too, can make an important contribution towards safety at work. We therefore ask you to read the operating instructions completely prior to commissioning the system. Observe the safety directives at all times!

Make sure that all persons working with or at the equipment also read the following safety directives carefully and follow them!

These Operating Instructions only apply to the equipment types indicated on the cover page.

Notice

This hand indicates useful tips for operation of the vibratory feeder.

Attention

This warning triangle indicates safety notices. Non-observance of such warnings may cause serious injury or even death.

• Make sure that protective earthing of the power supply system is in perfect condition!

• Never operate the vibratory feeder without guards and cover panels in place!

Intended use

The intended use of the vibratory feeder is the driving of sorting systems. They serve for linear transfer as well as correctly oriented and metered supply of bulk products.

Any other use, for example as vibrating screen or for material inspection applications, is considered contrary to intended use. Intended use also includes observance of the operating instructions and compliance with the maintenance rules. For the technical data for your vibratory feeder please refer to the table 'Technical Data' (Section 1). Make sure that the ratings of the vibratory feeder, control system and power supply are compatible.

Notice

Operate the vibratory feeder in perfect condition only.

Never operate the vibratory feeder in areas subject to explosion hazards or in wet areas. Operate the vibratory feeder only in the configuration of drive unit, control unit and bowl agreed with the manufacturer.

The vibratory feeder must never be subjected to any loads other than the products to be handled for which this special type has been rated and dimensioned.

Attention

It is strictly forbidden to disable any guards or safety devices!

Equipment user's duties

• Observe the directives given in the operating instructions for any kind of work (operation, maintenance, repairs, etc.).

• Refrain from any working practice that affects the safety at the vibratory feeder.

• Make sure that only authorised personnel work at the vibratory feeder.

• Give immediate notice to the management of any changes that have occurred on the vibratory feeder affecting

safety.

Attention

The vibratory feeder must be installed, put into operation and maintained by professional personnel only. Observe the legally binding provisions for the qualifications of qualified electrical workers and

instructed workers as defined by standards IEC 364 and DIN VDE 0105, part 1.

Notice

Electrical protection is provided by RNA's controller.

Rhein-Nadel Automation GmbH 8 VT-MA-SRC 160-800-EN_2019 / 20.03.2019 SJ

Noise emission The noise level at the place of use depends on the complete line in which the hopper will be incorporated and on the material to be sorted. For this reason, sound pressure levels in accordance with the 'Machinery' directive can only be determined at the place of installation. If the noise level at the place of use exceeds the permissible, sound-insulating hoods can be installed which we can offer on request (see our catalogue).

2.1. Applicable directives and standards

The vibratory feeders have been manufactured in accordance with the following directives:

• EC Low-Voltage Directive 2014/35/EU

• Electromagnetic Compatibility Directive 2014/30/EU

We assume that our product will be incorporated into a stationary machine. The requirements of the EMC Directive must be satisfied by the user.

The applicable standards are specified in the Declaration of Conformity.

3. Design and functional description

Vibratory feeders serve for feeding and orienting parts. The driving force is provided by an electromagnetic coil. The figure below is a schematic representation of a vibratory feeder:

Driving magnet D is rigidly connected to counter mass F. When the driving magnet is energized it exerts a force on armature E. This force is transmitted to bowl A mounted on spring packs C, causing the bowl to vibrate. The angle of the spring packs defines the direction of bowl movement.

Due to these vibrations the parts are lifted off the spiral feed track inside the bowl and thrown forward in tiny steps (micro throw principle). The direction of this throwing movement is perpendicular to the plane of the spring packs.

The driving magnet achieves its maximum power of attraction twice within each period of the alternating current. Consequently, the vibration frequency is double the mains frequency (100/120 Hz).

If heavy orienting tooling is mounted, the alternating current is changed to obtain a low vibration frequency (50/60 Hz). The vibration frequency of your feeder is indicated by the last digit of its type designation:

-1: 50 Hz-50 vibrations / sec.

-2: 100 Hz-100 vibrations / sec.

A vibratory feeder is a resonant system (spring-mass system). As a result, its factory set-up will rarely meet your onsite requirements. Section 5 describes in detail how you can adapt the vibratory feeder to your specific requirements.

Our optional accessories include a range of bowls covering a wide field of applications. For special applications we offer customized solutions.

The vibratory feeder is controlled by a low-loss electronic control unit. The choice of the control unit depends on the power input of the feeder. The following table indicates which control units can be used for which type of vibratory feeder:

The controller has a 5-pin connector on its front panel for connection to the vibratory feeder. Connector pin assignment is shown in the table 'Technical data' in chapter 1 of this operating instructions manual.

Notice For comprehensive information on the full range of control devices please refer to the 'Control Units' operating instructions.

All control devices have two essential operating elements:

• The power switch is used to energize and de-energize the vibratory feeder.

• A rotary knob (or buttons) can be used to set the feed rate of the orienting device.

Frequency controllers: For tuning of the vibratory feeders you may also use frequency controllers. For detailed description of the tuning procedure refer to the frequency controller operating instructions.

Caution: Electromagnetic field

Magnetic fields may affect a cardiac pacemaker. Therefore, persons wearing a cardiac pacemaker are recommended to keep a distance of at least 25 cm.

4. Shipment and installation

Shipment

Vibratory feeders are packed in sturdy wooden crates for shipment. After opening the lid, first remove the screws at the bottom of the crate securing the feeding system in place. An eye bolt is provided for handling of the vibratory feeder. You can attach a sling to this eye bolt and transport the feeder to its place of installation by means of suitable hoisting equipment.

Notice When unpacking and handling the vibratory feeder please observe the enclosed instruction sheet.

Depending on the feeder type we distinguish between following situations:

• For vibratory feeders whose bottom rests on the counter mass you must pull out the bottom to the top before you can screw in the eye bolt.

• For vibratory feeders with vibrating bottom (bottom bolted in place),it is mandatory to remove the central plug in order to screw in the eye bolt.

• For feeder bowls with central fastening, the bowl must be dismounted in order to screw on the eye nut.

• For vibratory feeder SRC-N 800 you can screw on the eye nut after removing the central plastic cap and domed

nut (M16).

Attention Do not sling or handle the vibratory feeder at or on the orienting device. Take care that the vibratory feeder cannot collide with other objects during handling operations.

Attention Make sure that nobody is under the vibratory feeder during handling operations.

Before commencing any handling operations be sure to verify that the hoisting equipment has a sufficient load carrying capacity. For the weight of the vibratory feeder please refer to the table 'Technical Data' (Section 1).

Notice The enclosed eye bolt is provided solely for purposes of handling the unit. Be sure to remove it before starting up.

Installation

At the place of installation the vibratory feeder should be mounted on the specially designed RNA support. If other supports are used make sure that they have sufficient load carrying capacity. This support must be dimensioned to ensure that no vibrations from the vibratory feeder can be transmitted.

Depending on the feeder type we distinguish between three mounting situations:

• Vibratory feeders with baseplate can be fastened from top. The required dimensions of SRG and USJ baseplates are specified in our Vibratory Feeders Catalogue on page 20.(Baseplates)

• Vibratory feeders without baseplate are fastened to shock absorbers (part G in overview drawing on page 9) from below.

5. Commissioning

Preparations

Attention

Make sure that the machine frame (rack, substructure, etc.) is connected to the protective earth conductor (PE). Protective earthing has to be provided by user as necessary.

Attention

It is imperative that the vibrating motor be connected to the equipotential bonding system of the overall equipment before commissioning. The adaptation points are marked with earth symbols. See also: DIN EU 60204 / VDE 0100-540

Attention Electrical connection of the vibratory feeder must be made by trained professional electricians only! When making any change to the electrical connection make absolutely sure that the 'Control Units' operating instructions are duly observed.

Verify that

• the vibratory feeder is arranged freely without contact to any solid body.

• the bowl is firmly bolted in place

• the vibratory feeder connecting cable is plugged into the control unit.

• The available electricity supply (frequency, voltage, power) must correspond to the connection data of the con-

trol system (see rating plate on the control unit).

Plug the cable of the control unit into a power socket and operate the power switch to energize the control unit.

Notice For vibratory feeders that are supplied as a completely set-up system the optimum feed rate has been factory-set. It is marked with a red arrow on the dial of the rotary knob. In this case set the rotary knob (or keys) to this mark.

Optimum tuning is achieved when the desired feeder speed is obtained with a controller setting of 80 %. In case of larger deviations (> +/- 15%) you should re-tune the system.

Tuning

Vibratory feeders are factory-tuned for standard feeder bowls (without orienting devices). To ensure optimum sorting behaviour the vibratory feeder has to be fine-tuned for the actual local operating conditions.

Tuning is done by adding or removing leaf springs and spacers. First check that the correct control unit is connected (see table with frequency, voltage and power ratings in Section 1). Now perform following steps:

• Unscrew the sheet metal enclosure. Firmly tighten all spring and bowl fastening screws. For the tightening torque of spring fastening screws refer to section 1 'Technical data'.

• Check that the magnets are compatible with the voltage and frequency ratings specified under Technical Data.

• Measure the air gap. Adjust the air gap to the correct setting if it doesn't match the values specified under Tech-

nical Data.

• Fill the bowl with parts. Switch the vibratory feeder on and set the feeding capacity to 90% via the rotary knob (or keys).

• Loosen the bottom fastening screw on one spring pack (by about a quarter turn or half turn).

Rhein-Nadel Automation GmbH 13 VT-MA-SRC 160-800-EN_2019 / 20.03.2019 SJ

When you loosen the spring fastening screw you can observe a change in feeder speed. The following graph shows the resonance curve of a vibratory feeder.

Notice The resonance frequency of the vibratory feeder must not be equal to the mains frequency, it should be lower than the driving frequency of the current.

If the feeder speed decreases after you loosen the spring fastening screw, proceed as described in section 5.1. If, on the contrary, the feeder speed increases, proceed as described in section 5.2.

Notice Tuning is facilitated by the use of an electronic frequency controller that is part of our standard product range.

The vibratory feeder should be tuned so that the desired feeder speed is obtained with a controller setting of approx. 80%. This is to ensure sufficient magnetic saturation.

5.1. Feeder speed decreases?

Install additional springs. Start by adding one spring (including spacers) to one spring pack. If the feeder speed continues to decrease after you loosen a fastening screw anew, install additional springs one by one progressively in another spring pack until the desired speed is obtained with the controller set at 70 - 80%.

5.2. Feeder speed increases?

Remove springs. Start by removing one spring (including spacers) from one spring pack. If the feeder speed continues to increase after you loosen a fastening screw anew, remove springs one by one progressively from another spring pack until reaching a range where the feeder speed decreases when you loosen the spring fastening screws. In this range the resonance frequency of the system is lower than the driving frequency of the current. Now proceed with the actual tuning procedure as described in Section 5.1.

Notice As the tuning procedure is done with the enclosure removed, be sure to add one more spring after finding the optimum setting. This compensates the influence of the sheet metal enclosure on the frequency. With type SRC-N 800 feeders, install 6 additional springs (one each in every 2nd spring pack).

Objective of the tuning procedure: To set a stable feed rate matching the requisite amount of product.

When the desired feeder speed is obtained at a controller setting of 80 %, the feeder speed must always decrease when the spring fastening screw is loosened.

Notice Make sure that the number of springs per spring pack will not deviate by more than 2 – 3 springs. Otherwise the feeder speed at the circumference of the bowl is no longer constant.

Rhein-Nadel Automation GmbH 14 VT-MA-SRC 160-800-EN_2019 / 20.03.2019 SJ

Feeder speed is not constant?

If the feeder speed in the bowl is no longer constant you can balance the bowl by adding counter-weights.

• Attach a counterweight to the side that is running fast.

If the addition of counter-weights is not possible, you can also proceed as follows:

• Remove a spring from the spring pack located on the 'slow' side.

• Add a spring to the spring pack located on the 'fast' side.

6. Maintenance

Vibratory feeders basically require no maintenance. They should only be cleaned when soiled or after coming into contact with liquids.

• Before starting such work pull the mains plug.

• Remove the enclosure.

• Clean the inside of the vibratory feeder, and in particular the air gap of the coil.

• After remounting the enclosure and plugging in the mains plug the vibratory feeder is again ready for operation.

7. Spare parts and customer service
