Innovative Usage of Vibratory Bowl Feeders - Vibratory Bowl Feeder for feeding various types and sizes of watch bases

by Monish Shete 25. April 2015 08:42

Elscint recently supplied a vibratory bowl feeder for feeding of various stainless steel watch bases for a major watch manufacturer. There were a total of 10 various sizes / dimensions comprising of 2 families of components. These also consisted of square and rectangular components. The requirement was to get them in a single row with the open side facing ground on a conveyor in lengthwise direction. Elscint provided a conical bowl with the least amount of changeover tooling to ensure operator ease. The changeover tooling too was made very easy with no adjustments and change parts were laser marked with the part number to make it easy for the operator to remember. Further, an extra capacity hopper having 50 ltr. capacity and a noise enclosure for the vibratory bowl feeder were also provided. The conveyor was provided with a variable drive with adjustable side guides. 

Innovative Usage of Vibratory Bowl Feeders - Elscint Vibratory Bowl Feeder for feeding two types of steel covers

by Monish Shete 19. April 2015 10:49

Elscint recently supplied a vibratory bowl feeder  for feeding of two steel parts in a single row. The part was very difficult to orient as there was a small tail on one side and no other difference. It was a “C” shaped part and the requirement was to get it in “open side facing sky with tail trailing”. There were two parts of same type but different sizes. Elscint removed the wrong parts by the use of a small air jet and then used machined outer chute to ensure that the orientation of the parts do not change afterwards during transfer to a linear vibratory track of 400 mm length. Elscint I linear vibrator was used for this purpose, again with a machine chute. A sensor was provided on the linear track to switch off the bowl feeder when the chute was full. Two separate tracks (orientation track in the bowl and the linear track were supplied for each of the components). The complete unit was supplied on a base plate to a special purpose machine builder.

 

 

Innovative Usage of Vibratory Bowl Feeders - Elscint Vibratory Bowl Feeder for feeding Ampoules in 12 rows

by Monish Shete 3. April 2015 05:15

Elscint recently supplied a special set of vibratory bowl feeders for feeding of glass in 12 rows. The speed or feed rate achieved was 75 Ampoules per minute per row in 12 rows. Two Elscint Model 630 vibratory bowl feeders were used for this purpose, each feeding 6 rows. The ampoules where oriented in base forward direction and outlets were provided in tubes. Stainless Steel flexible spring tubes were provided for each of the outlets. Elscint outer track bowls were fabricated in stainless steel. As the Ampoules were made of glass, there was a possibility of the Ampoules breaking while falling down in the bowl. Hence, Elscint provided FDA approved white colour Elscinthane PU coating for the bowl to ensure that even if they fall, there would not be any breakage. Additionally tooling was provided to reduce the fall of the Ampoules as they fall down. The bowls were pretty large in size (each one approximately 1200 mm in diameter). 

Innovative Usage of Vibratory Bowl Feeders - Auto feeding of Ceramic Rings for Centreless Grinding

by Monish Shete 22. March 2015 10:04

Elscint recently manufactured a supplied an auto feeding system for feeding of ceramic rings to a centerless grinding machine. The requirement was to feed 15 types of ceramic rings of various dimensions, right from diameter 20 mm to diameter 42 mm and thickness varying from 4 mm to 10 mm. The internal diameter too varied for the various rings, but mostly being 8 to 12 mm less that the outer diameter. For feeding to the customer’s centerless grinding machine, the rings were required to be fed axially. Due to the huge variety, to make the changeover between the rings easy, Elscint manufactured a special cylindrical design bowl made in stainless steel with separate changeover tooling for each of the rings. As the rings were having less thickness, there was a tendency of their toppling over. However, the tooling developed by Elscint ensured that this did not happen and the rings were fed in a stack to the grinding machine. Additionally, a linear vibrator with tubes was provided 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 contact between the bowl surface and the components. The complete system was mounted on a stand with an height adjustment of (+/-) 100 mm to ensure that the outlet tube can be aligned to the machine work-rest, whenever the ring size changes. 

One more extremely satisfied customer in the USA for Elscint

by Monish Shete 14. March 2015 12:04

It’s always nice to get a positive customer testimonial, especially one from an overseas customer. Elscint exported a double outlet feeding system for springs to the USA in October, 2014, details about the same were mentioned in the January Elscint Ahead Newsletter. The President of the company, Alfonso Jaramillo has written recently written to us –

“I am extremely happy with the performance of the Elscint feeding system. Elscint Automation has given us the ability to speed up our spring grinding system 600% and the process is now almost automatic with the exception of placing a box of springs into the vibratory feeder. We applaud Monish for his persistent effort in finding a way to accomplish this. We are very enthusiastic about our new machine we will for sure do more business with Elscint Automation in the near future.”

You can watch the video of the equipment working in his factory.

It is also important to note that a lot of bowl feeder manufacturers in the USA had expressed their inability to develop this system due to the fact that the springs had a tendency to entangle and also singulating them was not easy. But this was achieved with the patented Elscint Pneumatic Escapement, which can be seen in the video.

 

 

 

Innovative Usage of Vibratory Bowl Feeders - Elscint Feeding System for two types of rivets

by Monish Shete 3. March 2015 12:05

Elscint recently manufactured & supplied a complete feeding system for two types of rivets, delta rivet and normal rivet. The dimensions of the parts were around 18 x 25 mm (ht) and 15 x 23 mm (ht) respectively. Further in each type of rivet, there was a different rivet having extra height of 2 mm. One type of rivet was supposed to run in the system at one time and wrong rivet, if any, was supposed to be ejected out. The complete system consisted of two extra capacity elevator feeders of 75 ltr. capacity each for feeding each of these two rivets, two separate bowl feeders for feeding and orienting of the rivets, 4 linear vibrators, singling and checking systems. All this was mounted on a table big enough to even accommodate the robot of the customer. The elevators were kept outside the table. A see through acrylic cover was provided on the table to act as noise as well as dust enclosure. Limit switches were provided for each door opening. Even the elevator was covered with acrylic covers. Each feeding system had two linear vibrators. At the end of the first linear vibrator, there was a sensor to check the height of the rivet. If an incorrect size of rivet was fed, the same was removed into a bin with the help of a 3 stage pneumatic cylinder. The cylinder would travel backwards and release the incorrect rivet into a bin. In case of correct rivet, the cylinder used to travel forward and convey the rivet onto the 2nd linear vibrator which would take the rivet forward. At the end of the linear vibrator, there was a Singulating cylinder which moved the rivet 20 mm sideways for ease of pick up by the scara robot. Another customer requirement was “fast draining” in case change in the rivet size. For this, pneumatically operated gates were provided in the hopper elevator, the bowl and at the end point of the last linear vibratory track. This ensured fast draining of components within 60 seconds. Additionally, all the drains emptied in the same bin at the bottom of the hopper elevators, thus eliminating the need of the operator to go into the enclosure. The customer exported the machine to Turkey.

Elscint exports two outlet Vibratory Bowl Feeder for Springs to the USA

by Monish Shete 22. February 2015 10:02

Elscint Automation, the leading Vibratory Parts Feeder manufacturer from India has recently manufactured a vibratory bowl feeder for feeding of springs in two outlets. The wire diameter being small, these springs had a tendency of getting entangled between themselves. However, Elscint designed the bowl in such a way that the entangled springs fell back into the bowl and got disentangled while falling down. Only single disentangled springs came out of the bowl. Additionally, two tubular gravity feeder. chutes were provided so that two separate outlets could be provided at the centre distance required by the customer. At the end of the outlets, two separate Elscint pneumatic escapements (patented) were provided in order to release the springs one at a time. The customer required to feed the same to his disc grinder. Separate sensors were provided for the customer to actuate the escapements to release one spring at a time. The gravity chutes too had separate sensors in order to provide for “auto-switch off” once both the chutes were full. As there were two outlets, proper overflow was provided for each of these. The complete system was mounted on a stand made of aluminium extruded sections and height adjustment of (+/-) 100 mm was given. A speed of 120 springs per minute per row was achieved. Presently the customer was manually feeding springs and this automation certainly reduced his manpower and increased the speed of operation. The system was made to run on 110 V / 60 Hz supply as it was air shipped to a customer in the USA. You can watch the video of this bowl feeder for feeding of Springs.
