For ease of operation, it is necessary to ensure that there is a suitable relative position between the operator of the semi-automatic nail box machine and the operating components. To this end, the following points must be noted

① Commonly used operating components should be arranged as close as possible to the operators, and measures such as linkage can be taken. The height of the operating component from the ground should be set at a slightly lower position. The direction of rotation of the operating component should be consistent with the direction of motion of the driven part, and it is generally stipulated that clockwise rotation of the speed control handwheel is the speed increase and an indicator sign is attached to avoid misoperation The height of the storage bin for packaged items and auxiliary packaging equipment, as well as the position of the support for the roll packaging material, should be arranged appropriately. When the weight is large, it can be placed on the side of the machine to reduce height, and when the weight is small, it can be placed above the machine to reduce footprint. It is important to consider the overall appearance of the machine and try to place it in front of the semi-automatic nail box machine operator

② The height of the packaging machine workbench is generally selected within the range of 700 ^ -900mm. The above height should be appropriately reduced

③ The operator of the semi-automatic nail box machine should regularly pay attention to the most concentrated and prone areas of packaging operation. But for the packaging of large and heavy items, it is necessary to move them from left to right or rotate them clockwise. When determining the direction of the items, exceptions can generally be made when the packaging production line has special requirements

④ Temperature, pressure, speed, counting and other indicator instruments, as well as signal lights, alarms, safety valves, nameplates, etc., should be arranged in positions that are easy for operators of semi-automatic nail box machines to observe, safe and reliable, and easy to maintain.
