A manufacturing tray and system for ergonomic operations includes a tray, conveyance system, and loading and unloading stations configured with optimal dimensions and placement to allow an operator to load and unload trays while maintaining ideal standing posture. A conveyor system and trays transported thereon have a width less than the length of an average human forearm, while lanes of a tray rack and a flow rack open in front of a tray loading position on the conveyor. The height of the conveyor has a height approximately the height of the hips of an average standing operator. The tray includes a sliding rail for low-friction sliding of the tray along the conveyor. The tray may also include a handle which allows an operator to flip the tray position from vertical to horizontal or horizontal to vertical depending on whether the tray is to be stored or used.
摘要:
The invention relates to a tool for the electrochemical machining of a fuel injection device, the tool comprising an electrode holder and an electrode element which forms a cathode during the machining operation in order to be able to electrochemically remove material from the fuel injection device in a machining region. The electrode element is arranged in such a way that it can be displaced in relation to the electrode holder.
