3 Description of the VBF Vibratory Bowl Feeder 3.1 General The vibratory bowl feeder, together with bowl feeder, is designed for feeding materials at a single or multiple tracks. This machine is designed and manufactured for parts feeding which is based on the concept of trouble-free operation and labor saving.

The vibratory bowl feeder must only be used in combination with the corresponding controller. This combination guarantees optimum component feeding operational behavior.

The vibratory bowl feeder must be fixed onto a sufficiently rigid support, in order to avoid the conduction of vibrations to other parts

3.2 Functional description The vibratory bowl feeder is a manufactured part which transfers the part as result of electromagnetic oscillations The bowl feeder is installed on the top plate which is connected to the lower by means of the 4 epoxy sheet provided at certain angle, and they are oscillated through a magnet, so that parts on the bowl with the resonating force are moved up through the guide track resulting in little-by-little advancement of the component.

The basic construction of the vibratory bowl feeder contains the following elements.

1. Bowl feeder 2. Feeding direction3. Epoxy sheets 4. EM Coil

α Jumping - off angle β Inclination of leaf spring

The EM coil connected to the Iron core, creates a force which attracts and releases the leaf spring plate depending on the frequency of the power supply. The oscillation creates a rotary movement this tempts the material to jump from the guide track at each oscillation the component is conveyed as a result of the angle of inclination of the epoxy sheets connected.

VBF _EAF _ Manual 01 / 01 / 2016 9

With an alternating current of 50Hz, the Bowl Feeder carries out 100 oscillations per second, since the oscillating magnet attracts the magnet armature during current pulses. This oscillation of 100Hz is necessary in order to achieve smooth or gentle transport of parts however the weight factor for drive is depending upon the part and quantity parts to be fed which varies. In a Cycle of 50Hz alternating current supply, the magnet achieves twice its maxi-mum pulling force while this is independent of the direction of current flow. With heavy or large work pieces however, it is necessary to use an oscillating frequency of 50 Hz. A half wave of the mains supply is thereby blocked by the controlling devices.

4 Assembly instructions4.1 Transport

4.2 Installing the unit Each Vibratory bowl feeder system have 4 no’s of damping rubber mount and mounting block for mounting to the substructure with an adequate weight. While transportation the drive will be directly mounted to the mounting block .while it is been used with the bowl feeding system fig 2.

The following are the steps fix mounting

1. Remove the mounting screws from the substructure mentioned in fig 3.

2. By lifting the bowl slightly remove the mounting screw (2) from the mount-ing block

3. Fix the rubber mount to the bottom plate of the drive with respective mount-ing holes.

4. Fix the mounting block to the rubber mount using the screw (2).

5. Mount the mounting block with the drive to the provided substructure using screw (1).

The Vibratory bowl feeding system should be only lifted from bottom plate side only.

For the efficient operation of the vibratory bowl feeder it must always be mount-ed on a sufficiently supportive sub frame through the provided mounting holes in VBF mount, depending on the selected VBF.

The sub support should be plate or block design in order to absorb the vibration. The supporting profiles must be reinforced by a base plate or block on which the vibratory bowl feeder is attached. Required substructures are to be provided for the drive feeding systems. During the assembly of the vibratory bowl feeder make sure that the base is horizontal with reference to the mountable base. The elmech standard VBF mounting substructures will be also provided upon request

4.3 Mounting of the bowl feeder In order to achieve efficient transport speed, the following basic requirements must be achieved:

The bowl feeder are mainly classified to 3 types fig 5

1. Cylindrical bowl 2. Conical bowl 3. Stepped bowl

Depending upon the part to be fed the type is selected.

Fig 5

VBF _EAF _ Manual 01 / 01 / 2016 16

The installation of the bowl to the drive includes the following steps fig 6

1) The bowl should mount to the VBF top part using the provided mounting studs in the drive.

2) On the provided mounting stud mount the bowl

3) The structure of the bowl must transmit the vibration ideally with reference to the VBF considered.

4) The weight of the bowl (including parts) must not exceed the permissible weight limit depending upon the component.

4.4 Power supply

The below prescribed control devices can be used to activate the vibratory bowl feeder.

• SDVC 31 • REO MFS 168

Please note that an additional CEE connector plug is required for the controllers. Installation of the plug should be only to be carried out by technically qualified personnel

5 Operating instructions 5.1 Standard operations Basically there are no further settings required for standard operation once the control is switched on. An uninterrupted operation only requires the re-filling of the bowl.

5.2 Drive feeder specific adjustments.The Bowl Feeder system is basically a magnetic oscillation with the acting weight. It is operated by making use of resonance. This keeps energy consumption to a minimum.

The vibratory feeders are provided by the manufacturer, equipped with a standard oscillating system with EM coil. In order to achieve optimal feeding and sorting, the Bowl Feeder has to be adapted to the actual conditions of use. Adjustment is carried out by means of addition or removal of epoxy sheets.

The following steps are required for adjusting the Bowl Feeder:

1. Remove Bowl Feeder outer cover. 2. Check screws for the electromagnetic coil mounting and epoxy mounting

unit for tightness.3. Check air gap between electromagnetic coils and I cores. 4. Switch on Bowl Feeder and set controller device to the optimal feeding

values.

VBF _EAF _ Manual 01 / 01 / 2016 19

5.2.1 Feed rate increase / decreasesThe federate is the most critical constrain for the bowl feeding system which controlled by the frequency controller used. The decrease and increase in the feed rate can occur due to the below mentioned conditions.1. Optimal frequency and voltage not set in the control device.2. The air gap set is not set to the optimum values. 3. Faulty epoxy sheet mounted.4. Proper tightness not provided in the screws mounted in coil and epoxy

sheets.5. Outer cover not mounted properly.

6 Maintenance instructionsThe Bowl Feeder type is generally maintenance free but to be kept clean for effective working.In case of drive the epoxy sheets and the coil are the parts which will rarely require the replacement. Below mentioned are some of the parts in the system to be taken care.Clean the feeding system before it is started.All the orientation critical parts in the bowl should be cleaned to ensure proper working.Remove oil, grease or emulsions with a soft cloth or cotton waste.For cleaning the drive feeders without PU or urethane coating use solvents for e.g. acetone

6.1 Troubleshooting and fault repair

Disrupting caused by defective components must be repaired by replacing the defective component, only.

7.2 Control device The vibratory bowl feeder systems are connected to the 230/50Hz AC network via the control device. The control device can be made compatible for other supply voltages and frequencies. The vibratory bowl feeder operates in full wave mode with the double power frequency, i.e. at 50Hz AC with a mechanical 100 Hz vibration frequency.

Due to the change of the magnetic fluxes and thus the magnetic forces, the vibration displacement occurs and the components are being transferred. All controlling devices offer different setup for mounting as well as the activation. The controllers which are not related to EAF STANDARDS can also be used for as long as they meet the technical requirements.

7 Accessories 7.1 Mounting parts These are standard supporting setups provided for mounting the vibratory bowl feeder with the required bowl feeding systems excluding from this depending upon the customer requirement there are EAF custom made mounting accessories .
