Special Maintenance Items On The Assembly Line

- Oct 26, 2018-

(1) Inspection and lubrication

     In order to facilitate inspection and lubrication work, it is necessary to provide passages, platforms and railings, pedals or permanent ladders around the assembly line for easy access. The spacious upper space, convenient inspection holes, sufficient light, dry pits and tunnels are all material conditions for easy inspection of lubrication work.

     In order to be able to perform thorough inspections and lubrication frequently, there is also a lubrication and inspection work plan. The content requirement is first to determine a correct set of procedures, and secondly, in order to successfully implement these procedures, a clear post responsibility system must be established. Usually a preliminary part lubrication and maintenance chart is prepared. This chart is signed by the responsible person after completing the designated work task according to the specified time.


    (2) start and stop

     The conveyor should be started at no load and should be idling when possible when parked. Starting under load conditions not only increases the strain of the equipment, but also directly causes breakage. If, in some special cases, the conveyor or hoist must be stopped under load, a return gear must be used, whereas the directional movement and material are piled up at the end.

    (3) The size of the largest piece

     The maximum size of the material loaded onto the conveyor must be kept within the design and must be strictly enforced.


    (4) Prevent overloading

     The flow rate of the incoming equipment must be adjusted to within its energy permit. If it is inevitable that there are too many loads, you should set up a properly sized funnel and use a suitable feeder to unload the material. Material spills must be avoided, especially those that are prone to damage to the moving parts of the conveyor. This is because these scattered objects can easily bury or jam the moving parts of the moving parts, causing the mechanism to malfunction or be damaged.

    (5) Overload protection

     Despite the great care, accidental or accidental blockages can occur. In this case, the chain conveyor belt or the complete machine may reach the breaking load. A suitable method is to install an overload protector on the conveyor. This type of protection must be checked regularly (preferably once a month) to make sure its effect is effective.

    (6) Seasonal operation

     If the operation is seasonal (not to be idle for long periods of time), the equipment must be disassembled, cleaned, lubricated and preserved when not in use. If the disassembly is not easy to do, the idle equipment must be operated periodically for a short period of time so that its working parts are often kept flexible.

    (7) Spare parts

     The library must have enough spare parts for urgent needs. The complete chain, sprocket, conveyor belt and hopper to be replaced must be pre-ordered and stored for future use. Preventive maintenance is the best system to avoid losses caused by parking failures.

    Daily use, inspection and maintenance of equipment

     When the machine is running, the parts of the parts are worn out and go through three stages. Initially the initial wear stage. In fact, the peaks on the surface are quickly worn away, so it is also called the running-in stage. Followed by the normal wear stage. When the high point of the surface is flattened, the wear rate is stabilized and the wear is slow. Finally, there is a sharp wear phase. This is due to the too large clearance of the mating surface and loose work. At this time, the wear rate is quickly increased, and the fitting accuracy is rapidly lowered until it is damaged. Therefore, we set the end point A of the normal wear stage to a reasonable wear limit. From the above situation, the wear of the machine to a certain extent will reduce the productivity and product quality. For example, reasonable use of the equipment, careful maintenance, and enhanced inspection will prolong the normal wear stage, reduce the failure, improve the productivity, ensure the product quality, and extend the equipment. life.
