The steps of operation of the automatic machine 100 in sequence operated by the relay system 28 are as follows:

The method of working of the raw material gripper system 22 and the finished product gripper system 24 of the automatic machine 100 is as follows:
At the position of picking of raw material, the raw material will be exactly below the raw material gripper system 22. The pneumatic actuator 231 opens the piston which in turn pulls the pulling wire 233 through the actuator lever 232. The pulling of the pulling wire 233 results in the pulling down of the puller 225 which in turn results in the opening of the levers 226 and thereby raw material will be in between the two levers 226. The compression of the spring 224 happens during the pulling down of the puller 225. Now, the pneumatic actuator 231 closes the piston which results in the release of tension in the pulling wire 233 and due to counter action of the spring 224, the levers 226 closes and holds the raw material by means of two rubber pads 230. The two connecting links 227 facilitates in parallel movement of the two levers 226.

At the position of placing of raw material, the pneumatic actuator 231 opens the piston which in turn pulls the pulling wire 233 through the actuator lever 232. The pulling of the pulling wire 233 results in the pulling down of the puller 225 which in turn results in the opening of the levers 226 and thereby placing of the raw material inside CNC machine fixture.
At the position of picking of finished product, the pneumatic actuator 256 opens the piston which results in the pulling of the pulling wire 257. The pulling of the pulling wire 257 results in the pulling back of the convex finger 252 and thereby results in compression of the two springs 258. The backward movement of the convex finger 252 results in the backward movement of the two convex finger guide supports 242 attached to the convex finger 252 until the two convex finger guide supports 242 are obstructed by stopper rings of first type 246 located on their backside. At this position, the finished product will be in between the convex finger 252 and the concave finger 253 and the piston of pneumatic actuator 256 continues to open still further but due to restriction of stopper rings of first type 246, the convex finger 252 cannot move backward any further. This results in the creation of counterforce resulting in the forward movement of the two concave finger rods 254 until their movement is restricted by stopper rings of second type 247 at two support blocks of second type 245. Now, the piston of the pneumatic actuator 256 closes which results in the release of tension in the pulling wire 257 and due to the counter action of the two springs 258, the convex finger 252 moves forward until the finished product restricts the movement of the convex finger 252. This results in the creation of counterforce resulting in the backward movement of the two concave finger rods 254 until their movement is restricted by the finished product. At this position, the finished product is tightly held between the convex finger 252 and the concave finger 253. The pivot pin 248 facilitates the concave finger 253 to adapt to surface of finished product while holding the finished product.
When the piston of the pneumatic actuator 144 reaches its middle position while the hollow rectangular tube 142 is coming out from the CNC machine after the finished product gripper system 24 picks the finished product, the sensor 153 located at the middle

of the cylinder of the pneumatic actuator 144 sends a signal to the relay system 28 which in turn communicates and results in opening of the piston of the pneumatic actuator 256 ultimately resulting in pulling back of the convex finger 252 and thereby results in dropping of the finished product in to a pan positioned below.
Typically, at the position of picking of the raw material and at the position of picking of the finished product, the two levers of the raw material gripper system 22 and the convex finger 252 and the concave finger 253 of the finished product gripper system 24 remains opened.
Typically, in failure cases, when the finished product is not in between the convex finger 252 and the concave finger 253, the piston of the pneumatic actuator 256 closes which results in the release of tension in the pulling wire 257 and due to the counter action of the two springs 258, the convex finger 252 moves forward until the stopper rings of first type 246 restricts the movement of the two convex finger guide supports 242. This results in the creation of counterforce resulting in the backward movement of the two concave finger rods 254 until their movement is restricted by the stopper rings of second type 247 at two support blocks of second type 245. Ultimately, a clearance gap is created between the convex finger 252 and the concave finger 253 making the finished product gripper system 24 fool proof.
