How should I plan a new warehouse?

Warehouse FIFO Planning

1. Entering and exiting from different doors, entering from the warehouse, entering from the warehouse door, exiting from the warehouse door.
2. Combined order system, each box is set with two combined orders, one is posted on the box, and the other is placed in the folder, which is sorted according to the storage time. When the materials are needed, the earliest document time in the folder is preferentially removed and used.
3. Two-zone system. In the two areas of material deployment, the materials come in area A, and the materials are sent from area B. When the area B is completed, the identification signs of the two areas AB are exchanged.
4. Gravity feeding system, suitable for bulk materials, cement, rice, plastic particles, oil, bulk materials in a large warehouse, enter the warehouse from the upper part, out of the warehouse.
5. Relocation system, the material moves from one end or one side of the inspection warehouse to the sending end, to ensure the advanced appearance, shortcomings, each time the material is moved, the workload is large. (Cargo can be placed on wheels or wheels)
6. The shafted product is put on the steel frame with the shaft put on to realize the gradual movement from the storage end to the delivery end (at the same time to solve the problem of stacking height), a locking device must be provided.

Warehouse layout design
Position determination:
(1) Generally, it should be arranged according to the process of storage, acceptance, storage, sorting, and storage;
(2) Determine the position according to the operating frequency, and approach the door with high frequency.

Determination of the size of the cargo space:
The size of the storage space is related to the storage area and space utilization, and also whether the storage space can be smoothly accessed. The size of the storage space depends on the size of the headroom around the cargo unit. Consider the total amount of material.
Do not pay attention to cargo flow (large throughput should be placed in the shortest moving distance, including the main channel, low cargo space).

Functional area division refers to the comprehensive and reasonable arrangement of the various components of the warehouse—the storage area, the storage inspection area, the tally area, the distribution and preparation area, the aisle, and the auxiliary operation area within the prescribed range.
(1) Classified storage according to the characteristics of the goods, and store goods with similar characteristics in a centralized manner;
(2) Store goods with a large unit volume and a large unit weight on the bottom of the shelf, and close to the storage area and aisle;
(3) Store the goods with high turnover rate at the most convenient place for loading and unloading in and out of the warehouse;
(4) Centrally store the goods of the same supplier or the same customer to facilitate sorting and distribution operations.

Logistics relevance design
Straight line: the entrance and exit are on the opposite side of the warehouse, regardless of the size of the order and the number of items to be picked, they must go through the entire warehouse, which is suitable for simple and small-scale logistics operations

Double linear type: the entrance and exit are on the opposite side of the warehouse, but have two passages, which are suitable for similar logistics, but there are two different forms of logistics for import and export

Zigzag type: the entrance and exit are on different sides of the warehouse, and the route is zigzag, which is usually suitable for multiple rows of inventory shelves.

U-shaped: the entrance and exit are on the same side of the warehouse. According to the frequency of incoming and outgoing, the items with a large amount of goods are arranged in the storage area near the entrance and exit to shorten the picking and moving route of the items;

Diversion type: suitable for diversion operation of batch picking.

Channel design

Aisle type, passage in storage area, passage between warehouses (stock spaces);

The direction, width and number of the aisle, the aisle of the car is not less than 4 meters, and the aisle of the forklift is not less than 3.6 meters;

Make the loading and unloading of goods be one-way and linear movement, avoid reverse operation and inefficient operation that change direction greatly;

Places that are easily hit during transportation can be wrapped with soft materials (corners, columns, etc.)

Handling equipment design

1. Use high-efficiency material handling equipment;
2. Handling equipment is designed reasonably according to the shape of the materials in the warehouse. The forklift trucks of paper rolls are curved. The flats consider the rolling brake device and have soft protection.
3. The size, type and turning radius of the material handling equipment are limited to minimize the space occupied by the passage.

Cargo stacking design
Cargo stacking code refers to the general term of cargo stacking operation methods and methods. It is a method of stacking goods into various shapes according to certain rules according to the packaging, shape and storage requirements of the goods, combined with warehouse equipment conditions and storage time.

1. Basic requirements for cargo stacking
   (1) The quantity, quality and packaging of the goods must meet the requirements when they are officially stacked;
   (2) The stacking site needs to be dry and high. For the convenience of mechanical handling, pallets can be used;
   (3) Basic requirements for stacking: reasonable, firm, quantitative, neat, and economical.
2. Cargo stacking method
   (1) Place them as high as possible to improve storage efficiency;
   (2) the principle of “emphasis on light and priority on light”;
   (3) Select the location according to the frequency of delivery;
   (4) The principle of keeping the same variety in the same place;
   (5) the principle of easy identification;
   (6) the principle of facilitating points;
   (7) Arrange storage methods according to shape;
   (8) The cargo is easy to be scratched or scratched, and the pallet must have a protective layer of foam board;
   (9) When the cargo stacking is prevented from rolling, consider whether the cargo will be injured.
