In a production system, a double gripper robot performs a loading and unloading

Question

In a production system, a double gripper robot performs a loading and unloading operation for a machine tool. The work cycle consists of the following sequence of steps: Robot reaches and picks raw part from incoming conveyor in one 3.3 sec snipper and awaits completion of machining cycle. activity is performed simultaneously with machining cycle. At completion of previous machining cycle. robot reaches in. 5.0 see retrieves finished part from machine, loads raw part into fixture, and moves a safe distance from machine. 3 Machining cycle (automatic). 33.0 sec Robot moves to outgoing conveyor and deposits part. 1 his activity 3.0 sec is performed simultaneously with machining cycle Robot moves back to pickup position. This activity is performed 1.7 sec simultaneously with machining cycle. Discuss the features of the work cycle Identify the activities and process parameters for each step of the operation Is decision making required in this work cycle program? Justify your answer List 5 possible errors in this work cycle For each error list possible corrective actions

Explanation / Answer

a) workcycle is the sequences of activities and processes that are repeated from start to end to complete a job. It mostly consists of repetitive and sequential order in performing each activity with a specified time. The activites are predefined in their order and time.

b) the actiivty one is picking the parts from conveyor. it is loading. The activity two is unloading the parts from the finished product and loading them into loads the raw part into the fixture. The activity three is automatic. the activity four is depositing parts i.e unloading parts on coveyor belt. the activity five is robot going back to pick up position thus repeating the cycle again.

c) Yes decision making is required in the above workcycle program since the activity three is automatic and most of the activities are running along the maching time and there is waiting in activity one for machining time there can be some changes done to reduce the robot time by making changes.

d) Possible errors in the work cycle include robot waiting in the pickup position and and sequencing orders and the chance of wrong fixture of the product in the second step that could be reduced by assigning another action or step in three where the work is done automatically.
