Innovative Usage of Vibratory Feeders – Bowl feeder for feeding Bushes

by Monish Shete 1. February 2016 10:46

Elscint recently manufactured and exported a bowl feeder to South Africa for small bushes with a flange on one side. The bushes were of size flange diameter 14 x bottom diameter 10 mm x 6.7 mm ht. Two outlets were required with different orientation for each of these outlets. The orientation required was the flange to be facing each other. A particular centre distance too was required to be maintained between the two outlets. Again the scope included gravity chutes with sensors on each of these parts with a mounting base plate. As against required speed / feed rate of 15 parts per minute, Elscint achieved a speed of 100 parts per minute per outlet. As usual Elscinthane PU coating was provided on the bowl feeders to ensure that the bushes were not damaged due to constant rubbing on the metal bowl surface. The bowl was made of stainless steel. The gravity chutes too were machined out of stainless steel. The bowl feeder was completed before the committed delivery time and shipped to South Africa. You can watch the video of the bush feeder.

Innovative Usage of Vibratory Feeders - Elscint Vibratory Bowl Feeder for feeding small Pins

by Monish Shete 15. January 2016 04:27

Recently, an overseas customer approached Elscint, for feeding of small pins having diameter of just dia 2 and length of 6 mm. All the pins had one end flat while the other end was slightly tapered. The customer wanted all these to be fed in the pointed side forward orientation. Elscint used its Model 100 to feed and orient the same. A complete machined bowl made of stainless steel was used for this purpose. Additionally, the requirement was to provide a linear vibrator with a small chute of 250 mm and a non vibrating part at the end so that the operator can pick up the pins by his robot. The pointed portion being very minute and small, it was a very difficult job to orient. However, Elscint used its expertise to make it possible. The complete system was completed in less than 4 weeks and shipped to Finland. You can watch the video of the Elscint Bowl feeder for feeding the pointed pins.

Innovative Usage of Vibratory Feeders - Vibratory feeding system for feeding & Sorting of Uranium Pallets

by Monish Shete 1. January 2016 06:42

Elscint recently manufactured a vibratory feeding & sorting system for feeding of uranium pallets. The pellets had a diameter of dia 9.74 x 14 mm length. However, for the actual sizes, the diameter varied from dia 9.6 mm to dia 10 mm. Hence, Elscint provided a sorting equipment with two motorized counter rotating rollers to ensure that the incurrect pellets were sorted at an accuracy of 40 microns. The minus and plus pellets were sorted and collected in separate bins. The correct pellets were taken forward in a tube and singulated with the help of an electric actuator so that they would be kept ready for pick up by the customer robot. No pneumatics was to be used and hence Elscint used a 24 V Electric Actuator for the singulator. As the equipment was to be placed in a separate cell with no operator access and hence it was imperative that not a single pellet stayed in the unit and even the last one was removed without any manual intervention. The special bowl manufactured by Elscint ensured this. The uranium pallets being radioactive, it was ensured that no operator interface was required for any maintenance. The pellets also being brittle, it was ensured that their fall in the bowl feeder as well as after sorting was reduced to the maximum extent possible. The electrical panel was housed in a separate control box and kept at a distance of 15 mtrs. 

Innovative Usage of Vibratory Feeders - Elscint Four Headed Automatic Tapping Machine for M2 Tapping

by Monish Shete 21. December 2015 08:36

Elscint Automation, the leading vibratory parts feeder manufacturer from India recently completed an order for a four headed Automatic Tapping Machine. The part to be tapped was electrical Cable Nut. The tapping required was M2 and tapping depth was 1 mm. The customer requirement was for tapping at a very high speed. Hence Elscint recommended a 4 headed tapping head. Elscint used a cast aluminium bowl with tooling made in stainless steel with 4 outlets for feeding to the tapping head. Gravity chutes with escapements / singulators for each of the chutes were provided.

At the tapping station, tapping took place with the help of a specially designed four head spindle tapping attachment. The components were stopped with an (patented) Elscint pneumatic escapement while the tapping took place. After tapping, the tapped components were released / unloaded to fall into a bin. The bin had a provision for recirculation of the coolant / oil to be used for tapping along with a coolant tray. The machine had a PLC and a HMI for easy operator interface. The machine had option of running a coolant or tapping oil. Recirculation of the oil / coolant was also provided for. Sensors were used to check the possibility of tap breakage as well as for providing indication to the operator that the components in the bowl feeder were empty. The complete machine was enclosed in a dust free polycarbonate cover. A speed of 60 parts per minute was achieved. You can watch the video of this tapping machine.

Innovative Usage of Vibratory Feeders - Elscint Two Outlet Vibratory Bowl Feeder for condoms

by Monish Shete 13. December 2015 09:26

Elscint recently supplied a special vibratory bowl feeder for feeding of condoms in 2 rows. The speed or feed rate achieved was 75 condoms per minute per row in 2 rows. Elscint Model 400 was used for this purpose. Further a 800 mm long double track linear vibrator (Model Elscint II) was used to convey the condoms forward. The major problem with condoms is that they are rubbery and lubricated, making them slippery. This results in the speed being very less as the friction between the condoms and the bowl track is reduced, which does not allow them to move forward properly. However, Elscint provided a special type of bowl made of stainless steel for this purpose. Full welding was done at all areas to ensure that there were no crevices for dust accumulation. Another important point is that the mounting of the bowl has to be from outside to ensure that dust does not get accumulated in holes made for the screws required for bowl fixing. Hence, Elscint ensured the mounting was on the outer side on 12 screws. There being 2 outlets, proper overflow of parts was required and this too was taken care off.  The condoms being in various shapes, another possibility is that of overlapping and jamming. However, Elscint has perfected appropriate tooling for this type of bowl which eliminates this problem totally. Thus the feeding is very smooth without any overlapping or jamming. The fabricated bowl was having a diameter of more than 800 mm. Additionally, Elscint provided the complete system on a stand along with a hopper for extra loading capacity as the capacity of the bowl was limited.

by Monish Shete 23. November 2015 04:12

Elscint recently manufactured a vibratory bowl feeder for feeding a very thin contacts. The parts were having size 4 mm x 3 mm x 0.5 mm thickness with two slits on one side. The requirement was to get the slits towards the bowl centre as the contacts moved lengthwise. Due to the parts being very thin, there was a tendency of the parts coming double or jamming at the outlet. However, in the specially designed bowl feeder manufactured by Elscint, these possibilities were totally eliminated, resulting in smooth flow the parts at a high speed of 150 parts per minute.  Linear vibrator with 250 mm long track with a sensor attached to the same to switch off the bowl feeder was provided. Additionally, height adjustment of (+/-) 30 mm was provided for the bowl feeder and linear vibrator to make it easy for the customer to integrate with his system. The complete bowl was fully machined from stainless steel on a 5 Axis Vertical Machining Centre for achieving the required accuracy. You can watch the video of this bowl feeder.

Innovative Usage of Vibratory Feeders - Elscint Vibratory Bowl Feeder for feeding two types of metal parts with round belt conveyor feeder

by Monish Shete 10. November 2015 03:19

Elscint recently completed an order for a major multinational company where the requirement was to feed two types of metal parts with open side leading on to a centerless grinding machine. Both parts were having different geometries and hence, one part had to be oriented by making it stand up while the other part had to be oriented with respect to its weight balance. This resulted in the orientation tooling being very different for both the parts. However, Elscint provided a very easy changeover tooling to ensure operator ease. There were a total of 4 bowl feeders and Elscint ensured that all the tooling was interchangeable between all the 4 bowl feeders. Additionally, the requirement was for a 35 litre hopper feeder or stock feeder for extra loading capacity. There was a round belt conveyor ahead of the bowl feeder for further taking the parts upto the grinding machine. The customer was a 100 mm “X” Adjustment. This was provided and fine tuning of the same could be done with the help of a wheel. A zero to fifteen degree tilting provision was also provided. The whole structure was mounted on aluminium extruded sections and a polycarbonate aluminium guarding was provided for the complete machine. The centerless grinding machine was to be purchased from Japan and hence Elscint arranged to pack and transport one unit for trials to the Machine manufacturer in Japan. It was then sent back to India along with the grinding machine. The belt conveyor too was made from aluminium extruded sections and was driven by Elscint Geared Motor Model DM 38.
