VIBRATORY Bowl Feeders

Vibratory Bowl Feeders

Sandfield designs and manufactures custom made Bowl Feeding solutions which may also include Linear Conveyors, hoppers and Escapements to your precise specifications as well as providing a Bowl Feeder servicing and re-lining service. This combined with onsite support provides our customers with the complete package.

We have more than 20 years’ experience of designing, manufacturing, and servicing Bowl Feeders and offer customers reliable, robust Bowl Feeding Solutions. Each Vibratory Bowl Feeder is custom designed to meet your specific requirements depending on the size and shape of components, the required feed rate and running time. The systems are also designed to minimize downtime, thus optimising output.

The Highest Possible Level of Customer Service

One of our Unique Selling Points, is the time and trouble we take to ensure that your production line, and the bowls and feeding devices are designed in an optimum manner.

This often means visiting your facility and creating drawings and specifications for your consideration, prior to any orders being placed. Such is our dedication to providing the very best customer service.

Complete Range of Services

We provide a complete range of services and equipment associated with bowl feeding components, from a standalone Bowl Feeder to a complete Bowl Feeding system providing supplementary equipment including vibratory linear feeders, vibratory hoppers , belt conveyors, bulk loaders, and controllers.

Stainless Steel tooling is used on all Bowl Feeders and can be internally or externally tooled to suit the components. External tooling can produce much higher feed rates and also increases the storage space in the bowl top for components.

Bowl Feeders Speed Up Your Production Line

If you are running a production line where there is need to orientate small components, so that they can be correctly fed to into another part of the production process, then the chances are that you are using, or need a bowl feeder.

Factory Automation & Solutions

These feeders work by taking advantage of the fact that any small part, when gently shaken at the correct frequency, in a bowl, a conveyor belt or chute (these having to be shaped to fit the part), can slowly be agitated so that all the parts become aligned in a prescribed direction.

Dependable High-Speed Process

They can then leave the feeder’s conveyor one-by-one, the part being passed on to the next stage on the production-line, be it for assembly or to a packaging machine.

Your Part Handling and Material Flow Problems Solved

For example, certain parts cannot be dealt with simply using bowl feeders. In such instances, twisted conveyor belts are also used to turn parts over as needed. This is the sort of material-handling problem we will solve for you.

All Types of Bowl Feeders Supplied.

A specially shaped bowl, designed to orient the parts being processed into the specific orientation required, is at the centre of these units. Each bowl is mounted on a vibrating drive unit (available in piezoelectric, electromagnetic, and pneumatic forms), which is controlled with a variable-speed and amplitude control box. The vibration created forces the parts to move up a circular, inclined track. The sorted parts are then fed onto a track or Linear Feeder, this being gravity fed in some instances.

Linear Feeders – Connecting the Parts of the Production Line

On a production line, the machines can be some distance apart, this to allow for maintenance or the layout of the work floor. Linear feeders act as bridges between each stage, conveying the oriented components from the bowl feeders – multiple lines often being used, each with a different component. The distances can be short or relatively long, the latter creating an amount of buffer storage. These tracks use drive units which incorporate a multi magnet design, are robust, compact and virtually maintenance free.

Parts Escapements and Nests

Each linear track normally ends in some form of escapement device. These are the points on the line where some form of automated assembly equipment receives all the parts necessary for the next stage in the production process.

There are various types of Escapements

Static Parts Nests – A robotic arm is normally used to pick up the part, another part being dropped from the linear track immediately the part is taken.

Spring Loaded Hold Downs – The escapements here are of the ‘hold and release’ variant. Air pistons are used to release the parts in synchronisation to the needs of an assembly machine.

Pneumatic Hold and Release – This type of escapement uses pneumatic pistons to control the release of a part or product. A sensor is used to detect the presence or absence of a part on the track, back pressure being used to ensure an ample supply of parts.


Type of Industries That Use Bowl Feeders in Their Assembly-Lines

Vibratory feeders are used by many industries, including the pharmaceutical, automotive, electronic, cosmetic, food, like packaging and metalworking as well as fast moving consumable goods (FMCG). Other industries such as foundries, construction, pulp and paper, and plastics, not to mention recycling also use this equipment.

Economical Robotic Throughput

In all cases these vibratory feeders are used as they offer a cost-effective alternative to manual labour, thus saving time, and labour costs. When considering what type of parts feeder to select, your industry, the types of materials you are working with, the application and the volume of production must all be considered.

Bowl Feeder Specifications

Bowls are available from 150–1200 mm diameter and are either tooled internally or externally depending on requirements.

Bowl Feeders can also be supplied with linear conveyors to consistent, precise orientation and positioning of components. Bowl tops are available in Stainless Steel or Aluminium coated with Polyurethane with other coatings available as required.

Why would you need a Vibratory Bowl Feeder?

The common theme is the challenge of finding a robust, reliable, and efficient part feeding solution as part of an automated manufacturing process or application. If your objective is to improve cost efficiency and quality, whilst driving up production, Vibratory Bowl Feeders are the most reliable method for ensuring a consistent component flow for production machinery.

How to select the right Vibratory Bowl Feeder for your application?

Bowls are sized according to component size, run rate and re-stocking requirements. Please complete our Bowl Feeder Specification form so that we can advise on specification, costs, and delivery times.

More Information on Other Types of Feeders

  • Centrifugal feeder: These are also known as a rotary feeder. Whilst this system can work, the high rotating force required is not always suitable, with some components possibly becoming damaged.

  • Step feeder: One type of feeder that can also work as well as a Bowl Feeder, is the step feeder. This type also gently sorts parts, rotating them as needed with little or no vibration. This makes it a good choice if the parts to be sorter are very delicate.
  • Linear feeders: The linear motion of this feeder can handle uneven supplies of parts from equipment that is upstream of their position in the assembly line. This can be especially useful as it creates a smooth flow for downstream processes. It is however better if systems that run at a set rate are used throughout the line.
  • Carpet feeder: Where soft treatment of any oriented components (from bundle to escapement devices) is needed, this feeder s one to consider.
  • Axis vibration feeders: This robotic feeder uses a vibratory plate to evenly space out parts on a level surface, so that a manufacturing robot can easily pick them up.

Vibratory Bowl feeders are though, the most sophisticated reliable, useful, and robust system available on the market today, and offer the smoothest way of handling and sorting bulk products for further processing and packaging.
