Flare Nuts require to be fed to flaring machines. The hex head and the threading size in most cases of the flare nuts is the same and this makes orientation of the flare nuts rather difficult. However, Elscint has developed a unique type of bowl wherein Flare Nuts having head across flat equal to the threading can also be fed in the required direction at a very good speed. For this, either the Elscint Vibratory Bowl Feeder Model 250 or Model 400 can be used. Feed Rates or the speeds that can be achieved can be as high as 120 Pieces Per Minute. Further accessories like pneumatic escapement, stands, auto-switch off mechanism etc. can be provided to make the working convenient and easy for the operator. 

Bowl feeders are regularly required for feeding of Plastic Caps, mainly for feeding to Automatic Capping Machines as well other Special Pharmaceutical and Consumer Goods feeding Machines. These caps have to be oriented in one particular direction, which can either be Open side facing Sky or Open Side facing Ground or even the open side facing center of the Bowl or away from it. Speeds in such cases are very high, in the region of 60 to 300 pieces Per minute depending upon the size of the Plastic Cap. Caps of even upto diameter 120 mm or more can be fed in a vibratory bowl feeder. In most cases, in addition to a bowl feeder, a gravity track is required for taking the caps from the bowl to the conveyor / capping station which the cap is placed on the bottle. Further a stand too is required for mounting of the bowl feeder

Many times multiple outlets are required for a vibratory bowl feeder. It is better from the customer’s point of view to have a multiple outlet bowl feeder rather than getting purchasing multiple bowl feeders. One can have tracks from 2 to even upto 10 or more depending upon the part to be fed, the orientation etc. In fact, Elscint has developed a novel vibratory parts feeder, which can feed cylindrical components like needles, rivets, tablets etc. in ten tracks. Due to this, the output, which can be achieved through the bowl feeder can be as high as 8000 pieces per minute.

Chain circlips need to be fed during the assembly of chains at a very high speed. However, they also have a tendency of getting entangled. Hence Elscint has developed a Vibratory Bowl Feeder in which this problem is solved in an innovative way without even the usage of air. Consequently, the feed rate or speed that can be achieved is very high and there is no jamming of components in the track even if the outlet is closed / chute is full. This eliminates the requirement of having a Sensor for stopping the Vibratory Bowl Feeder every time the outlet chute is full.

Parts which make up a electron gun are very delicate and require careful handling. Hence, it is important not to handle them by hand and feed them automatically. This is where a bowl feeder comes into picture. The orientation of these parts is difficult though speeds are not very high. As the parts are plated and require shiny finish, there is a possibility of these parts becoming blackish while being fed in a vibratory feeder. Hence, it is important to provide PU coating for the bowls. Further for taking care of the critical orientation, it is preferable to get the bowls machined on a VMC machine.

Chains links are a very small part where the orientation is difficult and the required feed rate or speed is also very high (upto 300 pieces per minute). Not only is their orientation very difficult as there is very less difference between the two ends but the links being very flat and thin (0.60 mm in thickness) makes it doubly difficult. However, Elscint Automation (www.elscintautomation.com) has developed a Vibratory Bowl Feeder, which not only orients the links in the correct manner but also feeds them at a very high speed. The outer track is made in such a way to ensure that there is an overflow which means that there is no jamming of components in the track even if the outlet is closed / chute is full. This eliminates the requirement of having a Sensor for stopping the Vibratory Bowl Feeder every time the outlet chute is full.

Normally Vibratory Bowl Feeders are made for either Bolts or Nuts due to the intrinsic nature of the tooling required for each type of component. However, Elscint has developed a special type of Vibratory Bowl Feeder which can feed various types of Nuts and Bolts in the same Vibratory Bowl Feeder with slight changeover tooling. Bolts from size M 4 to M 14 and Nuts from M4 to M30 can be fed through the same Vibratory Bowl Feeder. This helps fastener manufacturers attain a lot of flexibility and adaptability with regard to the Vibratory Bowl Feeders. The changeover tooling is made in such a way that a range of bolts and nuts are fed in the same bowl feeder. The outlet of the nuts is blocked while feeding the bolts and while feeding the bolts, the outlet of the nuts is blocked. This makes the changeover tooling very easy.

Feeding of very large bolts or screws in a vibratory part feeder bowl is not possible. However, Elscint has developed an innovative feeding system for feeding of Bolts having size M 6 to M 24 and length between 30 mm to 200 mm. Any number of sizes between these dimensions can be fed through this type of feeding system. A chain elevator feeder and a custom built vibratory linear feeder are used in this case. Bulk loading of the bolts can be done at the ground level in a 200 Ltr. Hopper. The elevator feeder carries the bolts from the hopper to a height of about three meters from where they are unloaded onto a customized Elscint In-Line Rail Feeder which then transports the bolts in head up direction. A Pneumatic Escapement can also be attached to this equipment, if required. This releases the bolts one at a time on receipt of a 24 V DC signal. Speed of between 50 to 200 pieces per minute can be achieved depending upon the sizes of the bolts. The system results in a smooth flow of components without any starvation to the subsequent Machine.

Vibratory bowl feeders can be used to feed rivets and screws at a very high speed. Such components are usually required to be fed in head up orientation. The orientation is usually done on a Slot. Though this method is good for orientation, it reduces the speed of operation and requires usage of pneumatic air for increasing the feed rate and removal of unoriented rivets / screws and also requires a sensor for stopping the vibratory parts feeder when the chute is full. However, the vibratory parts feeder developed by Elscint Automation not only achieves a very high speed or feed rate but also does away with the usage of pneumatic air for orientation and removal of Component as also the sensor. Either of the five models of Elscint vibratory parts feeders can be used for this purpose depending upon the size and loading capacity required. This unit has a lot of applications in varied industries.

Vibratory bowl feeders are used for feeding and orienting of small components. There are numerous uses of these feeder bowls. One common usage of vibratory bowl feeders is for feeding of Engine Valves having dia from 20 mm to 50 mm and length between 30 mm to 200 mm. Depending up the valve size, a suitable model of vibratory bowl feeder can be selected. Thereafter, through a Pneumatic Uptake System, a bunch of Engine Valves can be transported up to a height of 2 Meters from the Ground Level for further feeding. This can be used for any machine like shaft strengthening machine, grinding machine, turning etc. Speed of between 40 to 100 pieces per minute can be achieved depending upon the sizes of the engine valves. Such a system results in a smooth flow of components without any starvation to the next machine and can increase the productivity of the engine valve producing unit by even upto 40%. The biggest advantage of this system is loading of the heavy engine valves at a height of just 500 mm, usage of the bare minimum space and flexibility of feeding various sizes of Engine Valves through the same feeding system. In fact, Elscint Automation (www.elscintautomation.com) has perfected this type of feeding equipment and can even sell only the vibratory bowl feeder or only the pneumatic take up unit. Elscint offers this in PLC and non-PLC (Electrical control) versions.
