25、 4.1.1 The operational characteristics of robots can be significantly different from those of other machines and equipment, as follows: a) robots are capable of high energy movements through a large operational space; b) the initiation of movement and the path of the robot arm are difficult to predi

26、ct and can vary, for example due to changing operational requirements; c) the operating space of the robot can overlap a portion of other robots operating space or the work zones of other machines and related equipment; d) operators can be required to work in close proximity to the robot system whil

27、e power to the machine actuators is available. 9DIN EN ISO 10218-2:2012-06 EN ISO 10218-2:2011 (E) 4.1.2 It is necessary to identify the hazards and to assess the risks associated with the robot and its application before selecting and designing appropriate safeguarding measures to adequately reduce

28、 the risks. Technical measures for the reduction of risk are based upon the following fundamental principles: a) the elimination of hazards by design or their reduction by substitution; b) preventing operators coming into contact with hazards or controlling the hazards by achieving a safe state befo

29、re the operator can come into contact with it; c) the reduction of risk during interventions (e.g. teaching). 4.1.3 The realization of these principles can involve: a) designing the robot system to allow tasks to be performed from outside the safeguarded space; b) the creation of a safeguarded space

30、 and a restricted space; c) provision of other safeguards when interventions have to occur within the safeguarded space. 4.1.4 The type of robot, its application and its relationship to other machines and related equipment will influence the design and the selection of the protective measures. These

31、 shall be suitable for the work being done and permit, where necessary, teaching, setting, maintenance, programme verification and troubleshooting operations to be carried out safely. 4.2 Layout design The design of the robot system and cell layout is a key process in the elimination of hazards and

32、reduction of risks. The following factors shall be taken into account during the layout design process. a) Establishing the physical limits (three dimensional) of the cell or line, including other parts of a larger cell or system (integrated manufacturing system): 1) scale and origin for modelling t

33、he layout in design drawings; 2) location and dimensions of the components within available facilities (scale). b) Workspaces, access and clearance: 1) identifying the maximum space of the robot system, establishing restricted and operating spaces, and identifying the need for clearances around obst

34、acles such as building supports; 2) traffic routes (pedestrian aisles, visitor routes, material movement outside the perimeter safeguarding of the cell or line); 3) access and safe pathway to support services (electricity, gas, water, vacuum, hydraulic, ventilation) and control systems; 4) access an

35、d safe pathway for service, cleaning, troubleshooting and maintenance purposes; 5) cables/other hazards for slips, trips and falls; 6) cable trays. c) Manual intervention the layout should be designed to allow tasks requiring manual intervention to be performed from outside the safeguarded space. Wh

36、ere this is not practicable and when the intervention requires powered movements of the machine(s), appropriate enabling devices shall be provided. The enabling devices may be designed to control: 1) the whole robot cell; 10DIN EN ISO 10218-2:2012-06 EN ISO 10218-2:2011 (E) 2) a zone in the robot ce

37、ll; 3) a selected machine or equipment within the cell. NOTE See ISO 12100 for more information. d) Ergonomics and human interface with equipment: 1) visibility of operations; 2) clarity of controls; 3) clear association of controls with robot; 4) regional control design traditions; 5) position of w

38、orkpiece relative to the operator; 6) foreseeable misuse; 7) collaborative operation. e) Environmental conditions: 1) ventilation; 2) weld spark. f) Loading and unloading the workpieces/tool change. g) Consideration of perimeter safeguarding. h) Requirements for and location of emergency stop device

39、s and possible zoning of the cell (e.g. local stops or full cell stop). i) Requirements for and location of enabling devices. j) Attention to the intended use of all components. The risk assessment shall determine the additional space required beyond the restricted space to define the safeguarded sp

40、ace. 4.3 Risk assessment 4.3.1 General Because a robot system is always integrated into a particular application, the integrator shall perform a risk assessment to determine the risk reduction measures required to adequately reduce the risks presented by the integrated application. Particular attent

41、ion should be paid to instances where safeguards are removed from individual machines in order to achieve the integrated application. Risk assessment enables the systematic analysis and evaluation of the risks associated with the robot system over its whole lifecycle (i.e. commissioning, set-up, pro

42、duction, maintenance, repair, decommissioning). Risk assessment is followed, whenever necessary, by risk reduction. When this process is repeated, it gives the iterative process for eliminating hazards as far as practicable and for reducing risks by implementing protective measures. 11DIN EN ISO 102

43、18-2:2012-06 EN ISO 10218-2:2011 (E) Risk assessment includes: determination of the limits of the robot system (see 4.3.2); hazard identification (see 4.4); risk estimation; risk evaluation. 4.3.2 Limits of the robot system The integration of a robot system begins with the specification of its inten

44、ded use and limits described in ISO 12100, ISO 11161 and other applicable C level standards. This specification should include, for example: a) use limits: 1) description of functions, intended use and reasonably foreseeable misuse; 2) description of the different user modes; 3) analysis of process

45、sequences including manual intervention; 4) description of interfaces, tooling and equipment; NOTE 1 It is advisable that the relevant C level standards for these devices be taken into account. 5) utility connections; 6) information supplied by the manufacturer, which is derived from the use of ISO

46、10218-1, including applied measures for risk reduction; 7) required power supply and their appliances; 8) required or anticipated user skills (competency); b) space limits (see 5.5 describing layout): 1) required machine movement range; 2) required space for installation and maintenance; 3) required

47、 space for operator tasks and other human intervention; 4) reconfiguration capabilities (ISO 11161); 5) required access (see 5.5.2); 6) foundations; 7) required space for supply and disposal devices or equipment; c) time limits: 1) intended life limit of the machinery and its components (wear parts,

48、 tools, etc.); 2) process flow charts and timings; 3) recommended service intervals; 12DIN EN ISO 10218-2:2012-06 EN ISO 10218-2:2011 (E) d) other limits: 1) environmental (temperature, use indoors or outdoors, tolerance to dust and moisture, etc.); 2) required cleanliness level for the intended use and environment; 3) properties of processed materials; 4) hazardous environments; 5) lessons learned, i.e. study and comparison, including available
