6.6 Mechanical design ignored the danger to humanity learn the principles of ergonomics to produce.

--- Unhealthy posture or excessive force

--- Inappropriate to consider a human arm or leg foot structure

--- Face inappropriate lighting

--- Human error, human behavior

--- Design, location or identification of manual control

--- Design or location of visual display device 5.2.2 5.2.2 6.3 6.3 5.2.2 5.2.2 7.1 7.2 7.3

7.4 Due to an unexpected start-up, operation accident/accident too fast (or any other similar faults) generated Danger.

--- Control system failure/malfunction

--- Energy recovery after the interruption

--- External influences electrical equipment

--- Operator operator error (machine with human features and capabilities do not match, see 8.6) 5.2.1 5.2.1,5.2.9 5.2.1 5.2.1,5.4.5,6.3

5.2.3 Start

5.2.3.1 General requirements See GB 5226.1-2008 in 9.2.5.2. For the purposes of this standard, "safety guards in place and functioning" by arrangement

5.3.7.1 interlock device achieved. The "run" refers to the wheel and saw motorized feed start. Band saw wheel drive motor can be run after all interlock devices in place and functioning. Mechanical feed should be driven band saw wheel motor to run after starting. Inspection method. check the corresponding drawings and/or circuit diagrams, inspection and machine tools for functional testing on the machine.

5.2.3.2 Log band saw machine On manually operated log band saw machine for mechanical feed controller should be "Stop - run" mode, there are interlocking guard around the machine Except for the bezel. On manually operated log band sawing machines, wood turning device controller should "stop - operation" mode, unless the timber by a rotating means With locking ring shield surrounded. Inspection methods. Verify that the appropriate drawings and/or circuit diagrams, inspection and machine tools for functional testing on the machine.

5.2.3.3 with table saw machine If the manufacturer on the bench with a band saw machine installed removable mechanical feed device, you should install a separate start control on the device Troller. Inspection methods. Verify that the appropriate drawings and/or circuit diagrams, inspection and machine tools for functional testing on the machine.

5.2.4 Normal stop

5.2.4.1 General requirements In the main control position shall be equipped with a normal stop manipulator, unless there is an emergency stop control this manipulator can meet the requirements of a normal stop and The manipulator can stop all machine actuation mechanism. Normal stop control system shall be as follows:

a) If the machine is equipped with an electrical brake shall be in GB 5226.1-2008

b) in other cases should be GB 5226.1-2008 9.2.2 0 in the class. When equipped with a category 1 stop manipulator, the normal stop order should be.

--- In addition to the workpiece clamping (if provided), the machine cut off all power actuating mechanism, causing the brake.

--- After completion of cutting off the brake force of the brake. The use of time relay, the delay at least equal to the minimum braking time. The relay should be fixed or the time delay adjustment device It is sealed. Inspection method. check the corresponding drawings and/or circuit diagrams, inspection and machine tools for functional testing on the machine.

5.2.4.2 feed device is equipped with a detachable belt table band saw machine If the machine is equipped with a removable mechanical feed device or electrically connected to a detachable motorized feeding device, shall request

5.2.4.1 An additional stop controller, and installed in the main control position. Inspection method. check the corresponding drawings and/or circuit diagrams, inspection and machine tools for functional testing on the machine.

5.2.5 Emergency Stop Shall comply with the requirements of GB 16754. In addition to not feed device with removable belt table band saw machine, all machines should be installed emergency stop actuator. If the machine is equipped with a mechanical brake, the emergency stop control system shall be in GB 5226.1-2008 9.2.2 0 class. In other cases, press GB 5226.1-2008

9.2.5.4 Classes 1 and the stop order should be 5.2.4. Avoid dangerous movements caused by gravity, pressure (for example, by an automatic mechanical stops or clamping device generated). Inspection method. Check machine corresponding drawings and/or circuit diagrams, inspection, measurement and test functions for the machine.

5.2.6 adjustment mode In Saw wheel diameter less than 1200mm and cut off the power that is open to the brake machine, when required hand turn Saw blade wheel adjustment, Should the saw wheels stopped, and then release the brake, and then make adjustments. On the saw wheel diameter greater than or equal 1200mm machine, and when no brake adjustment allows coasting mode selector should be provided, And should fully meet the GB 12557-2010 requirements in 5.3.4.2. Inspection methods. Verify that the appropriate drawings and/or circuit diagrams, inspection and functional test tools on the machine.
