by Monish Shete 18. October 2016 07:58

Elscint recently manufactured and supplied a 6 outlet bowl feeder to Romania. The part to be fed was a metal insert having dia 6 mm x 15 mm length. One end was having a smaller diameter (dia 4 mm) and the requirement was to get the smaller side forward. As the number of outlets were 6, Elscint used Model 400 with a 700 mm diameter cast aluminium bowl, coated with Elscinthane PU coating. The bowl track width was 50 mm and the parts were then taken forward in a tube. As there were 6 outlets, it was imperative that proper overflow arrangement was provided for each outlet. Further, flexible see through transparent tubes, each having length of 2 mtrs. were attached to each outlet. The bowl feeder was shipped to Romania by air freight. The speed achieved was 25 to 30 parts per minute per outlet, more than the requirement of the customer. You can watch the video of the equipment.

by Monish Shete 25. September 2016 10:49

Elscint manufacturer from India manufactures a high speed cap vibratory bowl feeder for feeding of caps. Elscint manufactures a total of 6 vibrator drives and due to the high speed, either model 400, model 400 HD or model 630 is used for this application. Various sizes of caps can be fed in the same bowl feeder with slight changeover tooling.


In fact, for a recent project, there were two caps, one having diameter 43 x 9.3 mm ht while the other one was having diameter 51 x 9.5 mm ht. and the speed required was 150 caps per minute. For this application, Elscint manufactured a special type of bowl wherein the speed achieved was 220 caps per minute for the one having diameter 43 mm and 185 caps per minute for the one having diameter 51 mm. This translates into a linear speed of 9.5 mtrs per minute (after orientation!). Elscint used a unique concept whereby such a high speed could be achieved. Model 400 with a cast aluminium bowl coated with Elscinthane PU coating was used for this application. Additionally, the changeover tooling too was very easy for the operator to change. Proper overflow arrangement was provided in the bowl so that the caps would fall back into the bowl in case the outlet was closed.

Elscint Vibratory Bowl Feeders for Conical Washer

by Monish Shete 23. August 2016 06:28

Elscint recently manufactured a Vibratory Bowl Feeder for feeding of Conical & Flat Washers. The Washers were having outer diameter from 24 mm to 50 mm and thickness of 2.2 mm to 5 mm in ht. Due to its conical curvature, the washers have a tendency of coming in a bunch and it is difficult to remove one out of the bunch. Orientation too is very critical as the Washer is being used in a SPM which cannot detect wrongly orientated pieces. This makes it pertinent to have a bowl feeder that not only feeds correctly oriented parts consistently but also feeds them in a single row, thereby eliminating the chances of double feeding of the washers. For this Elscint used a stainless steel bowl with a reverse track which eliminated the double washers automatically. Additionally ahead of the bowl feeder, a linear vibrator with 800 mm track length having an auto-switch off mechanism and mounting arrangement was provided. After the linear vibrator, a Singulating arrangement with a Festo make cylinder with 60 mm stroke was provided to singulate and push a single washer forward. A mounting stand was provided for the complete system.

by Monish Shete 16. August 2016 08:31

Elscint recently manufactured & supplied a complete feeding system for feeding of bearing cups to a centerless grinding machine. The work also entailed linking of two centerless grinding machines. For the first machine, Elscint used Model 630 with a dia 1100 mm stainless steel bowl coated with Elscinthane PU coating. It oriented the cups in “Axial with open side forward” orientation and fed the same onto a linear vibrator, namely Elscint I which then transported the bearing cups upto the workrest of the centerless grinding machine. After grinding, a stationary, non-vibrating chute of 600 mm was used to convey the bearing cups ahead. Then it was connected to a vibrating chute mounted on a linear vibrator which further conveyed the bearing cups 800 mm to the next grinding machine. After the second grinding operation, the bearing cups were again taken forward by 600 mm on a non-vibrating chute and then onto another vibrating chute of 800 mm with a stopper arrangement. The operator was supposed to pick and pack the bearing cups from the end of this track. The complete system was manufactured in record time and installed at the customer’s end by Elscint.

by Monish Shete 3. August 2016 12:39

Elscint recently manufactured and supplied a vibratory bowl feeder for feeding of plastic screws having dia 7 mm head x 9 mm length. The requirement was to feed the plastic screws in a single row at a speed of 30 parts per minute with singulation. Elscint recommended its Model 250 with Linear Vibrator Model Elscint I HD. Model 250 has a bowl diameter of 400 mm ensuring a lot of loading capacity, thus eliminating the need of a separate hopper and level control. A speed of between 60 to 65 parts was observed with singulation. A sensor was fixed on the linear vibrator to switch off the bowl feeder once the linear track was full. The singulation was made with the help of a specially designed fixture with Festo make cylinder. The screws being white in colour, Elscinthane coating was provided on the bowl to ensure that they do not get coloured or dirty during usage in the cast aluminium bowl with stainless steel tooling. The equipment was supplied to a customer in Mexico and hence was made to work on 110 V / 60 Hz input power. Frequency controllers were supplied both for the vibratory bowl feeder and the linear vibrator. Confirmation videos were sent to the customer for his approval and then the system was packed and dispatched by air freight mode to Mexico.  You can watch the video of the equipment.

Innovative Usage of Vibratory Bowl feeder - Elscint high speed vibratory feeder for large plastic spouts with in three rows with Cap Up

by Monish Shete 28. July 2016 11:39

Elscint, recently manufactured a bowl feeder for feeding of large spouts in the orientation Cap up / Tail down in three rows. The spouts were having a cap of dia 35 mm and length of 40 mm. Elscint manufactured a step type bowl having diameter of 1200 mm to be used with its Model 630 drive unit which is a four coil version with 1500 VA rating. The spouts were mostly coming either with the cap down or else in lying fashion. Elscint ensured that most of spouts were made in cap down forward (even the ones coming lying down) and then there were bifurcated into three rows and taken forward. Thereafter the spouts were turned in 180 degrees to ensure that the cap was up. This was done on wire cut rods for good accuracy. Afterwards, the spouts were taken forward on a linear vibrator of 800 mm length and a centre distance of 80 mm was maintained between each of the spouts. Speed required for 60 spouts per minute per row and Elscint achieved a speed of 80 spouts per minute per row. A sensor was provided on the innermost row of the linear vibrator (which was the slowest one). This ensured that the bowl feeder could be switched off, reducing noise and power requirement.

Innovative Usage of Vibratory Bowl feeder -Vibratory bowl feeder for feeding of various screws to Eddy Current Testing Machine

by Monish Shete 14. July 2016 08:45

Elscint recently completed an assignment wherein the requirement was to feed various types of screws for testing to an Eddy Current Testing Machine. There were various sizes of screws right from M4 x 20 mm length to M16 x 120 mm length. A single bowl feeder was required for the same. Elscint used its Model 630 with a bowl diameter of approximately 1050 mm. This ensured that even the biggest part of M16 x 120 mm length was fed as well the storage too was enough in the bowl. Further, a linear vibrator was provided with adjustable tooling which again ensured that all these parts were fed properly. Ahead of the linear vibrator, a pneumatic singulator was placed which released one screw at a time on receipt of a signal from the Eddy Current Testing Machine. To make changeover easy, Elscint provided separate tooling fixtures for each of the screws with separate pneumatic cylinders. The changeover was on just 4 screws, making it very easy for the operator. Additionally, a stand with height adjustment was provided to ensure adjustment from 700 mm to 1100 mm to match the input height of the Eddy Current Testing Machine. The bowl was coated with Elscinthane PU coating for reduction in noise level as well as better performance.
