Verein Deutscher Ingenieure Guideline 2860) 1 Handling is a subfunction of the materials flow and categorized on the same level as conveying or storing effecting materials flow conveying VDI 2411 storing VDI 2411 handling VDI 2860 Handling is divided into the following single steps: • Store • Change Quantities • Move • Secure • Control 26 Handling: The Underrated Process 1.3 What Are The Main Points of. .. workpieces 17 1.1 The Handling Process The process of handling component parts or workpieces in production is often underrated as technically simple or even trivial From the production point of view it is obvious that the workpiece itself does not increase in value during the handling process As far as technical solutions are concerned, handling is secondary to the manufacturing process The time necessary... Book? The following chapters focus on the realization of handling technology tasks Keynote is the process of integrating a workpiece into a moving device and put it into a new position or orientation In order to illustrate the subject in a sensible selection we draw the analogy to human object handling In line with this analogy we concentrate on gripping techniques which follow mechanical principles... valuable machine time; or at least to keep handling time at a minimum and to move as many workpieces as possible per time unit Machine time and handling time have to be coordinated: Machinery idling during workpiece handling is generally not acceptable, just as fast robots waiting for machinery do not make sense 21 Handling: The Underrated Process gripping moving placing start 1 Influencing factors... is separated into machine time and handling time (see figure 1.2) Machine time is the period of time during which a machine is operating, i e making changes to the workpiece itself Machine time can be further separated into pre-operating time, operating time, and post-operating time Pre- and post-operating time include all necessary operations before and after operating time, such as supplying a tool... analyzed and evaluated at an early stage 22 Handling: The Underrated Process Setup The term is used in connection with the availability of workpieces A workpiece is made ready when it is able to be gripped Handling Handling means creating, defined changing or temporarily maintaining a pre-set alignment of geometrically defined bodies in a system of coordinates Further parameters such as time, quantity, and... or coolant These intervals have been reduced to a minimum by high traverse rates and appropriate control technology over the past few years Handling time or auxiliary process time can be separated into single steps from setting up a workpiece to testing it Production planning aims at synchronizing handling time and machine time in order to prevent time-consuming handling processes from taking up valuable... of a handling process and its ambient conditions The handling process can be basically characterized by counting the workpieces moved per unit of time This characteristic, however, does not specify the amount of technical requirements for obtaining a desired cycle time Complex workpieces and multiple ambient conditions can create different handling tasks to such an extent that a simple task of moving... declining kinetic performance distinctly declining kinetic performance Table 1.1 Phases of human motor skills Table 1.1 details human motor skills changing throughout a lifetime For the technical recording of kinetic processes, a distance-time diagram is used which depicts illustration of various movement features This method can also be used for determining the fine motor skills necessary for gripping... Vacuum grippers and other gripper types are included but not covered in detail However, workpiece movement with moving axes and robot technology from the gripper finger to the six-axis robot arm are thoroughly described 1 Chapter 1 explains terms and fundamentals of the subject Chapter 2 gives an insight into the history of automation technology and robot development over the past 30 years, highlighting the . separated into machine time and handling time (see figure 1.2). Machine time is the period of time during which a machine is operating, i. e. making changes to the workpiece itself. Machine time. separated into single steps from setting up a workpiece to testing it. Production plan- ning aims at synchronizing handling time and machine time in order to prevent time-consuming handling processes. obvious that the workpiece itself does not increase in value during the handling process.
