Elscint recently supplied a special set of vibratory bowl feeders for feeding of condoms in 6 rows. The speed or feed rate achieved was 75 condoms per minute per row in 6 rows. Two Elscint Model 630 vibratory bowl feeders were used for this purpose, each feeding 3 rows to a single linear vibrator. A single linear vibrator with 6 rows was provided with a pitch of 55 mm between two condoms. For this linear vibrator Model Elscint IV 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 3 outlets for each vibratory bowl feeder, 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 was very smooth without any overlapping or jamming. The fabricated bowls were having a diameter of more than 1200 mm. Elscint also provided two separate hoppers for each of these bowls, ensuring higher loading capacity so that it can be a truly manless operation.

Elscint recently completed an order for a double head Automatic Tapping Machine. Two different components required tapping. However, the tap size and the pitch was same for both the components. Hence, Elscint suggested a single tapping machine with two bowl feeders but a single tapping machine (with 2 spindles). The advantage was saving of costs. The components were fed through two separate vibratory bowl feeders to the individual tapping stations by a gravity chute. At the tapping station, tapping took place with the help of a specially designed double spindle tapping attachment. The components were stopped with an (patented) Elscint pneumatic escapement while the tapping took place. Further, the components were also clamped separately to ensure they do not twist or turn during tapping. After tapping, the tapped components were released / unloaded to fall into a bin. Two separate bins were provided for each of the two components. The machine had provision to run either both or either of the components. The machine had a PLC and a HMI by which the operator could select which component to run. This provided the customer with the required flexibility for its production run. The machine had option of running a coolant or tapping oil. Recirculation of the oil / coolant was also provided for. The complete machine was enclosed in a dust free polycarbonate cover. You can watch the video of this tapping machine.

Elscint, the leading vibratory bowl feeder manufacturer from India recently manufactured a vibratory bowl feeder for feeding of special nuts. The nuts were flat and having a curved portion on one side making the orientation difficult. However, Elscint perfected the orientation by providing three places for confirmation of the orientation. The special nuts were required to come out in two outlets making it more critical. Additionally, a 600 mm long linear track and a non-vibrating pick up point was provided at the end of the linear track for easy part pick up by the customer’s pick and place unit. The whole system was mounted on a single post stand having a (+/-) 100 mm height adjustment. In order to increase the life of the equipment, Elscint used hardened and ground parts for not only the linear track but also the orientation plates as the special nuts were hard. Elscint unit its Model 250 vibratory bowl feeder with a cast aluminium bowl lined with Elscinthane PU coating. The parts being metallic, the Elscinthane PU coating eliminated the metal to metal contact between the bowl and the metallic components, thus reducing the noise level to just 70 Db. A total of 2 such systems were delivered to the customer.

Elscint recently completed an assignment wherein the requirement was to feed 40 types of components of various dimensions. The parts being carbide inserts, which, though small were very heavy. They required orientation and additionally, some inserts were having diameter more than length, some having diameter equal to length and some length more than diameter. Hence, Elscint provided a total of 4 bowls with changeover tooling for each of these. In most cases, the lot sizes were small and hence, a small bowl feeder (Model 250 with bowl diameter of around 400 mm) was used. This made bowl as well as tooling replacement very easy. The lot sizes in most cases too were less and this made the small bowl convenient. For higher lot sizes, Elscint provided a 50 ltr. Hopper feeder which could accommodate the larger quantity. Further, having a hopper feeder ensured that the bowl feeder was always having only a certain number of components, so that the load on the vibrator was constant in all cases, providing a constant feed. Elscint also provided a linear vibrator with tubes to accommodate different sizes of components for further feeding to the centreless grinding machine. This provided a constant pressure and push to the parts when they entered the grinding machine. The bowl was coated with Elscinthane PU coating, ensuring that the noise level was less by eliminating the metal to metal contact between the stainless steel bowl and the carbide inserts.

Elscint recently manufactured a vibratory bowl feeder where very small rivets were required in two rows in head up orientation. The usual tendency of such rivets is to come in head down orientation. None of them come in the required orientation of head up. Hence, Elscint first ensured head down orientation and then used a sector type track to turn them upside down, ensuring that the final orientation of head up was achieved. Further, as there were two outlets, proper overflow was needed to be ensured on each of the outlets. The bowl was a double start bowl which was completely machined. The sector and linear track too was machined with high accuracy and a polycarbonate see through cover was provided for the linear track. Speed of 100 rivets per minute per row was achieved which was more than the requirement of the customer

Elscint recently manufactured a vibratory bowl feeding system for feeding grading and blow feeding of hex bolts of the size M8 x 39 mm having a flange. The diameter of the flange was to be checked. In case of oversize or undersize flange, the bolt had to be rejected and only the correct size of bolts had to be blow fed through two separate tubes to two separate stations 5 meters away. Elscint used Model 400 vibratory bowl feeder with a cast aluminium bowl with Elscinthane coating which has a loading capacity of 30 kgs for feeding of the bolts. Thereafter, segregation of the bolts with respect to the undersize and oversize flange was done by using two counter rotating rollers. These rollers ensured that the undersized and oversize bolts fell into separate bins earmarked for the same. The correct size of bolts were then singulated and blow fed through proper flexible tubes to the required stations (two numbers). For this pneumatic cylinders were used with a fixture which ensured that each of the stations was fed on receipt of the required signal from the end of the customer. The whole equipment was mounted on a table as per the requirement of the customer. The complete electrical and pneumatic system was manufactured by Elscint and supplied to the customer. Even commissioning of the equipment was undertaken at the customer’s end.
