TS Transmission Mechanism (TM) - Transition of the Trolley Between Bay 2 and Bay 1

The transition of the trolley between Bay 2 and Bay 1 is described by a sequence of states and events.

State 6: Empty trolley is in transit between Bay 2 and Bay 1

B2: (Bay 2 states)

• The operator withdraws the left and right dish pins (2 pins). The springs expand upwards pushing the dish up and raising the plate and thus the rack attached underneath it. The pinion then rotates thus activating the belt-pulley mechanism. The drive wheel on the ground starts rotating and the trolley moves.
• The trolley travels from Bay 2 to Bay 1 (state 6)
• The trolley arrives at Bay 1 (state 7)
• The operator engages the two plate pins
• The trolley is at rest at Bay 1; the springs are in the relaxed mode. (state 1)
