Feeding of stud bolts through a vibratory bowl feeder is a regular feature, however, most of the times they are fed in head up orientation or else in axial or length wise orientation. In case one wants to use them in stem / tail up direction, a costly pick and place mechanism has to be employed for the same. To get over this problem, Elscint has developed a special vibratory bowl feeder which feeds the stud bolts in head down position i.e. with the stem up. Any of the 8 models of vibratory bowl feeders manufactured by Elscint can be used for this purpose depending upon the size of the stud bolts being fed. A wide size of stud bolts are also possible to be fed in the same bowl with slight change over tooling. Very high feed rates ranging from 80 pieces per minute to 300 pieces per minute are possible again depending upon the size of the stud bolts. This unit, which finds applications in the Fastener Industry as well as other allied Industries where such components are required.

Elscint has developed a special type of Vibratory Bowl Feeder for segregating assembled and semi-assembled Radiator Valves through a Vibratory Bowl Feeder without the need of a costly vision system. The Radiator Valve Assembly has five parts. Even if any one part is not assembled in the Radiator Valve Assembly, the same must be rejected. There are numerous permutations and combinations that need to be segregated. The same has been made possible by development of a special type of Vibratory Parts Feeder. Elscint Vibratory Bowl Feeder Model 400 is used for this purpose. A feed rate of 150 Pieces Per Minute is achieved with this Bowl Feeder. This unit is available at a very competitive price in a very low delivery period. This has helped reduce the time lost while making the final Radiator Assembly for the customer. This unit finds application in the Automobile Industry. With the help of this technology, Elscint can undertake segregation of a variety of Components through Vibratory Bowl Feeders. Elscint Hopper Feeder with Elscint Linear Feeder (Inline Rail Feeder) is available as an accessory for increasing the loading capacity.

Once you order a Vibratory Bowl Feeder, you might be called to inspect it before shipping. In such a case, you need to check whether the following points are taken care of -

1. Suitable Overflow Arrangement - When a bowl's production output (feed rate) is greater than the production needs of the end user, he components will have to fall back in the bowl and remain vibrating in place. This may not be required in case one has an Auto-Switch off Mechanism built in the chute or the Linear track. However, still, a good Vibratory Bowl feeder should have a suitable overflow arrangement. The "overflow" system helps you save on the cost of the "Auto Switch off Mechanism" and its attendant controls.

2. Replaceable Tooling - Areas of the bowl that are prone to wear and tear include the sections that change the velocity or orientation of the part. If wear is anticipated and unavoidable, then replaceable tooling can be developed for the bowl. This can include stainless steel tracks and bowl linings, spill offs, scallops, wipers, and virtually any other tooling. Replaceable tooling also makes it easy to "retool" the bowl for another component in case your component changes or a new component is added in that "family" of components.

3. Bowl Linings - Though they are often used for noise level reduction purposes or for increasing the parts drive, various linings can be used to extend the wearable life of a bowl. However, best results are found with sprayable Polyurethane coatings / linings. These linings also increase the life of the bowl. In case of oily components or where there is presence of coolant / oil, such linings help in increasing friction between the bowl and the components and facilitate feeding. The best type of coating is the Elscinthane PU coating.

4. Bowl material - Bowls can be made of mild steel, stainless steel, cast aluminium and polyamide. The best of of these are cast aluminium bowls. They provide flexibility of tooling and there can be a modular approach to tooling. The tooling can be changed easily when the components change. The tooling can be made in stainless steel so that the wear and tear is less.

Elscint manufactures a Sorting & Grading Unit for small Shims. The Elscint Sorting and Grading Unit is designed to feed, sort and grade components like shims which require to be graded according to their thickness. This Unit operates at a speed in excess of 150 pieces per minute, depending on the size of the components. The system utilizes an Elscint Vibratory Bowl Feeder of suitable mode amongst the 6 Models of Elscint Vibratory Bowl Feeders. The Bowl Feeder feeds the parts to a set of powered gauge rolls. These are powered by an Elscint Geared Motor of suitable rating. The inclination of the rolls, plus adjustable roll spacing from one end to the other enables parts to move / travel easily and rapidly into the desired position, while moving them to the discharge point. Undersized parts are first separated, followed by those within tolerance. Oversize and damaged or oversize parts continue to the end of the rolls and are discharged into a separate container. An important feature is that the rolls being counter-rotating does not bind or grip the parts and are extremely sensitive to fine tolerances. The basic unit works on a fixed speed, however, optionally Elscint can also offer Sensor and a variable speed AC or DC motor fitted with an Elscint Reduction Unit. This unit offers high flexibility for the user and can also be used for sorting and grading of Balls, Taper Rollers, Pins and similar components.

A lot of System Integrators start the process of ordering/ speaking to a Bowl Feeder manufacturer only after their design work is complete. However, this is suicidal on the part of the System Integrator. It is better that he consult with a Vibratory bowl Feeder manufacturer before starting his Design work. The reason is that a particular part might be very difficult of orient as required by the System Integrator for this future operation / assembly. However, it might be very easy to orient if used in another way. This might result not only in saving a lot of cost but also future head aches and problems on part of the System Integrator. Hence, it is beneficial for the System Integrator to speak / consult a Vibratory Bowl Feeder manufacturer at the design stage itself.

Also, early in the design stage of an assembly machine, the parts used in the assembly should be analyzed to determine how well they can be fed in a Vibratory Bowl Feeder. Another important consideration is how reliably a part will orient in a Bowl feeder. A part needs some geometry that allows the bowl tooling to distinguish one side from the other, or one end from the other.
