· 12. Simple principle: Simplify handling by eliminating and reducing unnecessary movement and equipment.

Applications: repeated handling, material flow backwards, storage planning is too cumbersome.

· 13. Gravity principle: Considering the loss of safety damage and other factors, use gravity to move materials as much as possible.

Application: Material moves from low to high level.

· 14. Safety principles: follow safety principles and use safe material handling systems and methods.

Application: Simple and dangerous self-made transportation facilities, without prior training of workers, operators of material handling equipment without formal training, no guards to protect materials, hanging loads with pallets, loads exceeding floor, shelf and structural loads, equipment Overspeed operation, shelves are not marked front and back, lack of automatic sprinkler and fire alarm, dangerous and flammable materials are not clearly marked and isolated, fire equipment is incomplete, entrances and exits are not safe, and there is no fire emergency plan.

· 15. Computerization principle: Use computers in material handling and storage systems to enhance the control of materials and information by the material handling system and material handling procedures.

Applications: Lack of instruction records for guided channel tracks, shipment orders are not printed in the order of shipment, and accumulated orders are manually classified.

16. System flow principle: When handling material handling and storage, integrate data flow and logistics flow.

Applications: The equipment is not dispatched in time, the materials are waiting for written work, the automatic identification system is not used, the parts are not prepared in advance before manufacturing, and the acceptance work is not notified in advance.

· 17. Layout principle: For all feasible solutions, prepare the operation sequence and equipment design, and then choose the most effective solution.

Applications: long handling distance, cross paths, poor workplace layout, improper service area configuration, improper checkpoint location, unmarked aisle and storage location, unplanned aisle length, lack of narrow and extra narrow track storage storage equipment, Material handling equipment does not cooperate with the exit, the parking station does not have a lifting platform, the parking station is not fenced, the number of parking station doors is not appropriate, the reception and transportation operations are not appropriately dispersed, the lighting, heaters and fans are not properly arranged, the ventilation of Air conditioning and temperature are inappropriate, materials, people or equipment move too long, and the walls and ceilings are not reasonably isolated.

18. Cost Principle: Compare the cost of material handling per unit for different solutions.

Applications: mastering too much material, idle handling equipment, excessive freight costs, high overhead costs

· 19. Maintenance principle: Prepare a plan for preventive maintenance and regular maintenance for all material handling equipment.

Applications: Material handling equipment maintenance costs are too high, too many waste products are not removed, load beams sag or shelves are distorted, and there is no preventative maintenance plan.

· 20. Elimination principle: Considering the product life cycle, there is a long-term and economical reasonable policy for outdated equipment updates.

Application: The handling equipment is not suitable, there is no equipment update plan, and the handling equipment is old. In addition, there is no reward system for material handling personnel.

The ultimate purpose of the company's material handling system is to reduce the handling costs under the premise of ensuring the normal production of the company, and to ensure that the company's products are sufficiently competitive in the market. In modern enterprises, the cost of material handling generally accounts for about 20% to 30% of the total product cost. In the machinery industry, the cost of material handling is as high as 35% to 40%. Therefore, reducing the operating cost of the material handling system is one way to increase corporate profits. way. Due to the imbalanced development of various regions and industries in China, the production types of different enterprises are different. Only the main and general handling principles can be determined to optimize the material handling system for the enterprise and improve the efficiency of the material handling system. (1) Improve material activity index.

(2) Containerization and unitization of materials (such as containerization, palletization, and standard containerization).

(3) Bulk material handling conveyor.

(4) Rationalization of material activity index and handling equipment handling index configuration.

(5) Linearization of the material handling system (ie the shortest handling distance).

(6) Seamless docking of the material handling system (materials are transported as far as possible without landing, loading and unloading, direct transportation).

(7) Reasonable, suitable and practical mechanization, automation and unmanned.

(8) Balanced handling of the material handling system.

(9) Rationalize the configuration of the handling equipment in the material handling system (that is, the system is capable of handling at full capacity to avoid the formation of functional islands due to excess or insufficient capacity and performance of certain equipment in the system).

(10) Gravity handling.

(11) The largest conveying unit (the conveying unit should be as large as possible under the conditions allowed by the conveying equipment).

(12) The principle of maximum use of space (in the storage system, use space as much as possible to reduce land costs).

(13) Safety principles (accidents are the biggest cost waste).

Improving the efficiency of modern logistics systems and reducing logistics costs are not only a technical issue, but also a series of logistics system management issues. That is to say, a modern logistics system composed of modern logistics technology equipment requires modern management methods and modern thinking methods to ensure that the technical capabilities of its modern logistics system are fully utilized.
