Testbed Sequences

3. Animate operational sequences

The TESTBED_VIEWL system configuration can be used as shown below to produce static animations of both normal and abnormal operational sequences for the Sortation/Inspection testbed .

The image size is reduced from the original TESTBED_VIEWL configuration by changing the DIA parameter of the resources in the VIEW device from 40 to 30.

A Web animation of this system is available here.

3.1 Normal operation [Blocked][Starved]

The sequence shown below is one of many possible normal operational sequences, depending on the relative speed of operation of the various physical components of the system and the order in which pegs and rings are fed to the chain.
1. A ring is fed into the supply transfer bar (s1).	2. The ring has arrived at the sortation area and the sort solenoid has begun its motion (s2).	3. The sortation is complete and the ring has arrived at the rotary solenoid, which has begun operation (s3).	4. The ring has been moved to the assembly area by the rotary solenoid, which has returned to its original position.

5. A second ring has been deflected from the sortation area to the rotary solenoid area, and a peg has passed the sortation area.	6. The peg slides down the chute.	7. The peg is carried by the belt toward the assembly area (s4).	8. Assembly has completed (s5) and the rotary solenoid has advanced the second disk to the assembly area. The assembled combination has passed the inspection station (s6) and will proceed to the delivery chute (s7).

3.2 Blocked operation [Normal][Starved]

In this abnormal operational sequence, sortation of a ring is blocked when a ring is already present in the upper hopper. The ring will then fall off the end of the chain into a surplus ring hopper.

3.3 Starved operation [Normal][Blocked]

In this abnormal operational sequence, a peg passes throught the assembly station when a ring is not available. It will then be deflected into the reject bin.
