Innovative Usage of Vibratory Bowl feeder - Vibratory bowl feeder for feeding 4 types of metal parts in 4 rows

by Monish Shete 1. July 2016 11:07

Elscint recently completed an assignment wherein the requirement was to feed 4 types of metal parts with the head forward and threading trailing in 4 rows. The parts were having diameter 11.5 mm and the ht. varied between 30 mm to 40 mm. The profile of all the 4 components was also different. As 4 rows were required, overflow was required in each of the 4 rows to ensure that there is no jamming once the outlet tracks are full. However, Elscint provided a sensor on the slowest row so that once it was full, the bowl feeder could be stopped, ensuring lesser noise and savings on power. Elscint used its Model 400 vibratory bowl feeder with a bowl diameter of approximately 800 mm for this purpose as 4 outlets were required and plus space was required for overflow of each of the tracks. A speed of 25 to 35 parts per minute per row was achieved as against the required speed of 12 parts per minute. The bowl used was stainless steel and coated with brown Elscinthane PU coating for reduction in noise level as also to ensure better performance of the same.

Supply of Vibrator Drives to Spain

by Monish Shete 15. June 2016 10:30

Elscint recently supplied 10 vibrator Drives (Model 250) along with a few linear vibrators to Spain to a Spanish Vibratory Bowl Feeder manufacturer. Earlier, the manufacturer was making its own drives. However, a couple of months back, Elscint supplied one vibrator to him for testing and approval. The manufacturer was very happy with the quality and performance of Elscint drives and immediately ordered the first set of 10 drives to Elscint. These were sent by sea freight, freight pre-paid. The Spanish customer plans to keep these in stock, use them for their own bowls as well as supply the same all over Europe to other bowl feeder toolers. Elscint vibrators are not only having CE Marking but also compatible with respect to the base mounting as well as bowl mountings to major European makes. The performance too is comparable, if not superior to European makes. Finally they are very competitively priced to make them attractive to European bowl toolers. Further, Elscint provides springs free of cost with each supply for the first tuning purpose. As against this, European manufacturers charge for spare springs. In a similar fashion, Elscint can also supply untooled bowls too.

Innovative Usage of Vibratory Bowl feeder - Feeding system for Carbide drill bits for Centreless Grinding

by Monish Shete 2. June 2016 06:20

Elscint recently completed an assignment wherein the requirement was to feed 2 types of components of various dimensions. The parts being carbide inserts, which, though small were very heavy. They required orientation was axial with the dome shape to be forward. The parts being heavy, Elscint suggested Model 250 which has a load carrying capacity of 30 kgs with a cast aluminium bowl with stainless steel tooling. The cast al bowl was coated with Elscinthane bowl coating to ensure smooth operation even in the case oil or coolant was present. It also reduced the noise level resulting due to the touching of the metallic bowl to the metal parts but also with respect to the metal to metal contact between the components themselves. Hence, a rough texture was given for the coating. 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. A stand with 100 mm plus and minus height adjustment was provided to ensure ease of operation with integration with the grinding machine of the supplier. 

Innovative Usage of Vibratory Bowl feeders - Feeding & Inserting of Plastic Filter into Regulator Housing

by Monish Shete 24. May 2016 06:14

Elscint recently supplied an integrated a vibratory bowl feeder for feeding of a small dia 12 mm x 3 mm plastic filter. The requirement was to first orient and feed the plastic filter through a vibratory bowl feeder, then singulate the same and push it into the Regulator Housing of the customer. The regulator housing was to be kept on an indexing table manually by the operator. Elscint’s scope was upto the insertion into the regulator housing. The insertion was to be 40 mm inside the housing, making it difficult as this had to be done during the indexing mechanism. Elscint used a small vibratory bowl feeder of approximately 200 mm in diameter (Model 160 with a cylindrical bowl) for this purpose. The filters were oriented in “rolling” orientation and taken vertically down where they were singulated with a cylinder. Then another cylinder having a 120 mm long stroke with guide rods was provided to push the filter into the Regulator housing. The cylinder time was 2 seconds per component and this was easily achieved. Elscint completed the equipment and its service engineer installed and commissioned the same at the customer’s factory in the South of India within record time. You can watch the video of the equipment.

Innovative Usage of Vibratory Bowl Feeders – Feeding ofr Coffee Cups

by Monish Shete 14. May 2016 11:53

Elscint  recently manufactured a bowl feeder for orientating and feeding of two types of coffee cup. One was having a diameter of 37 mm x 24 mm ht with a small flange. The other cup was slightly smaller in size. The requirement was to feed the cups in rolling orientation. Speed required was 100 parts per minute. Elscint used a stainless steel step design bowl, mounted on Model 400 for this application. The cups used to come in any direction. However, Elscint turned most of the cups and used 90% of the cups coming up. Hence, the speed achieved was more than 150 cups per minute. The cups were oriented in “Flange up” orientation in the bowl and further twisted to make them “rolling”. Then they were carried further in a vertical gravity chute. 600 mm before the end of the vertical chute, the cups were singulated using the patented Elscint Escapement mechanism with a Festo make ADN series double acting cylinder. This ensured that only one cup was released at a time, on receipt of a signal from the customer’s end. Elscint provided the complete system including F/R/L, solenoid etc. making integration with the customer’s machine very easy and fast. You can watch the video of the equipment.

by Monish Shete 2. April 2016 03:43

Elscint recently manufactured a Syringe feeding, Adhesive Dispensing & Piston pressing Machine wherein a large plastic syringe of 45 x 28 x 104 mm length was fed through a big vibratory bowl feeder, namely, Model 630 with a bowl diameter of 1100 mm onto the first station of a 6 station indexing table. At the next station, two separate types of adhesives were dispensed into the two capsules of the syringe. After the dispensing was complete, the table was indexed and the piston was fed from another big bowl feeder, Model 630 once again. For both these bowl feeders, gravity chutes of almost 1 mtr. Length were used for providing sufficient buffer. The fourth operation on the indexing table was assembly and pressing of the piston into the syringe (20 mm inside). The fifth station was a “blank” one as they customer wanted to have a provision of checking of the adhesive, if required, in the future. At the sixth station, the dispensed and assembled syringe was ejected into a bin. The speed achieved was 28 parts per minute, including the dispensing of the adhesive. Siemens make S7-200 PLC was used along with Festo make pneumatics for the machine. You can watch the video of the equipment.
