* It is convenient for managers to send and receive, check and maintain, and facilitate loading and unloading operations.
* It is convenient for information system management, and fully improves the operation efficiency and storage utilization rate.
2) palletizing requirements
* light light, big not small, heavy not light. Signs are intuitive and clear, and labels are outward.
* corners should be neat and firm.
* The channel width is appropriate and easy to operate.
* Goods of different varieties, specifications, batches and manufacturers should be stacked separately. The stacking spacing is10cm. In order to ensure the convenience of "first in, first out", they should be stacked in the order of purchase.
* Bagged goods are finalized and palletized, and the center of gravity should tend to be in the crib; The mouth of carton packaging and barreled goods should face upwards; Damaged packages should be stacked separately.
* Stacked goods must be accepted and allowed to be put into storage; It should be well packed and clearly marked.
3) Stacking method
Stacking operation depends on forklift and other equipment combined with labor, and acts according to storage requirements.
* For bagged goods, the "five-five-style" stacking method that is convenient for measurement can be adopted, which is convenient for reading, neatness, inventory and delivery.
* For small items and parts of various specifications, such as bearings, electronic products and various accessories, shelf stacking method should be adopted. Variety, specification, model, etc. Storage should be distinguished, and similar goods should be stored on the same shelf as far as possible for easy access.
* Pallet stacking method: operate according to the packaging situation of goods and the storage pressure of the warehouse.
4) Stacking
The purpose of stacking is to prevent moisture, which should be determined according to the performance and climatic conditions of the goods. The padding material can be linoleum, cushion, etc. And when wood is used as padding, it should be treated as moisture-proof and insect-proof.
5) thatch mulching
In order to prevent the goods from getting wet, a cover can be used. After the cover, the goods should be stacked smoothly and tightly, and there should be no rain and snow leakage. Can be used for poncho, linoleum, canvas, etc. Pile up the shapes of the goods and cover them directly with tarpaulins.
2。 protect
1) warehouse temperature and humidity control method
* Ventilation
Using the air pressure difference caused by the different air temperatures inside and outside the warehouse, the air inside and outside the warehouse forms convection, thus achieving the purpose of adjusting the humidity inside the warehouse. When ventilating, open the window at the upper leeward side and open the warehouse door to promote the complete circulation of air in the warehouse. The warehouse keeper can determine the length of ventilation time and the number of doors and windows opened during ventilation according to the actual situation. On windy days, the pressure of the wind can accelerate the air convection, but the wind force should not be too strong (there will be more dust if the wind force exceeds level 5).
For materials that are afraid of heat, ventilation is mainly used to cool down. In hot season, materials with low temperature requirements can be ventilated at night or around 6 am, 1-2 times a week.
For materials that are afraid of freezing, ventilation is used to raise the temperature. In the cold season, when the sunshine is sufficient and the temperature outside the warehouse is the highest, usually from 2 pm to 3 pm, ventilation is needed. You can do it every day.
For materials that are afraid of tide, ventilation is used to reduce tide. Ventilation should be carried out under the condition of low absolute temperature outside the warehouse, which is the most in autumn and winter, the second in spring and the least in summer, and can be carried out at an appropriate time.
Hang the hygrometer in the warehouse. The blood glucose meter should be placed in a place with good ventilation and no sunlight. Don't hang them on the wall. The hanging height is about 1. About 5 meters. The temperature and humidity in the warehouse must be observed every day to determine the change of temperature and humidity in the warehouse.
* hygroscopicity
In rainy season or rainy day, when ventilation is not suitable, moisture absorption can be used to reduce the humidity in the warehouse. A hygroscopic agent or a mechanical hygroscopic method can be used.
2) Prevention and control of mildew of stored goods
* Strengthen warehousing acceptance. When the moldy articles are put into storage, the packaging should be checked for moisture, and special attention should be paid to regular inspection during storage to strengthen protection.
* Strengthen the temperature and humidity management of the warehouse, especially in rainy season, so that mold is not suitable for growth.
* Choose a reasonable storage location. Moldy articles should be arranged in a warehouse with good ventilation, strong light and relative dryness as far as possible, and should be avoided from being stored with commodities with high water content.
* reasonable stacking, mat moistureproof mat. Goods should not be stacked against walls or columns.
* Do a good job in daily cleaning and hygiene. The dust accumulated in the warehouse absorbs moisture and is easy to parasitize fungi.
* Chemical reagents to prevent mildew. Appropriate chemicals can be used to prevent goods or packaging from mildewing and rotting.
* For moldy but treatable goods, drying, baking and fumigation should be selected according to the nature of the goods to prevent mildew and rot. And re-test the sample of the article, and those who pass the test can continue to use it.
3) Prevention and control of pests and rodents in warehouses
* once every six months to the reservoir area for drug pest control, pest control, not regularly catch mice.
* Keep the reservoir area clean and hygienic, so that pests and other organisms are not easy to grow and hide.
* Inspection and treatment of pests on incoming materials.
4) Corrosion of metal objects and prevention methods
Metal corrosion is mainly aimed at external factors affecting metal corrosion, and storage conditions should be controlled and improved.
The warehouse for storing metal articles should choose a high-lying, dry place without water. Metal commodities such as more sophisticated hardware tools and parts should not be stored in the same warehouse as chemical commodities or commodities with high water content. Coating (or dipping or spraying) a layer of antirust grease film on the surface of some metal products for antirust treatment.
Derusting methods include manual and chemical derusting;
* Manual derusting
Manual derusting uses wire brush, copper wire brush, sandpaper, emery cloth, etc. Grind the surface of rusty objects and remove the rust layer. For rough steel, it can be polished with wire brush or coarse emery cloth (paper); Metal products and parts with average precision can be polished with fine abrasive cloth (paper); Metal products with coated or polished surfaces can be polished with emery cloth dipped in polishing paste and decontamination powder.
* chemical derusting
Chemical derusting is a chemical reaction between acid solution and corrosion products on metal surface to achieve the purpose of derusting.
The pickling process comprises the following steps:
Degreasing → washing → pickling → washing → phosphating → surface adjustment → washing → natural drying.
3。 first-in first-out
The first-in-first-out management mode of materials can prevent materials from deteriorating due to long-term accumulation.
* In order to ensure the convenience of "first in first out", they should be stacked in the order of purchase.
* effective and reasonable location division and management of the site in the warehouse. Warehouse administrators should be familiar with the purpose and rules of warehouse location.
* Kanban management is implemented at the warehouse site, and delivery tasks are clearly and effectively executed.
* On the inventory card and login account book, the items of the same kind, the same factory and the same specification are numbered from 1 at the beginning of each year in the order of purchase time. When leaving the warehouse, the warehouse keeper should check the remaining quantity of the earliest batch of goods on the inventory card and deliver the goods according to the principle of "first in, first out".
4。 Stock turnover rate
Through the calculation of inventory turnover rate, the inventory turnover rate of key materials is adjusted to realize the effective utilization of inventory assets and improve warehouse management.
Calculation formula of inventory turnover rate:
Inventory turnover rate = monthly issued quantity/monthly average inventory quantity.
Average monthly inventory quantity = (monthly inventory quantity 1 day+monthly inventory quantity of 30 days) /2
The warehouse shall calculate the inventory turnover rate of last month at the beginning of each month, when the turnover rate is
Reasons, shorten the procurement cycle, investigate the safety inventory, and relevant personnel of various departments put forward improvement opinions and measures to optimize the inventory turnover efficiency.
Verb (short for verb) Inventory check:
Material inventory inspection refers to the inspection of the quantity and quality of inventory materials, so as to count the actual quantity of inventory materials and ensure the consistency of accounts, materials and cards; Find out the actual varieties, specifications and quantities of materials that have exceeded the storage period and have been overstocked for a long time, so as to handle and check the profit and loss quantity and reasons of the inventory materials;
Through the inventory requirements, the quantity, specification and quality of the inventory materials are clear, the accounts are clear, the profit and loss are well-founded, the accident damage is well-founded, and the adjustment is well-founded, so as to ensure the accuracy of the inventory materials.
1, contents of inventory inspection
1) Check whether the actual inventory of materials is consistent with the figures on the debit card, and find out the reasons for the profit and loss of materials;
2) Understand the quality of stock materials, and recheck the samples if necessary, in case of rust, mildew, deliquescence and moth-eaten;
3) Find out whether there are overstocked materials that have exceeded the storage period and have not been used for a long time, and find out the reasons for the overstock;
4) Check whether the stacking is stable, whether there is water and sundries on the site, whether there is rain leakage in the warehouse, whether the ventilation holes of doors and windows are in good condition, whether the temperature and humidity of the warehouse meet the storage requirements and whether the cleanliness meets the requirements.
5) Check whether the measuring tools are accurate and whether the use and maintenance are reasonable;
6) Check whether all kinds of safety measures and fire fighting equipment are complete and meet the safety requirements.
2, the method of inventory inspection
1) For warehouse managers, when daily materials change dynamically, the inventory method should be carried out in batches and in categories. After receiving each batch of materials, the warehouse will make a receiving and dispatching inventory card in advance and stick it on each batch of packaging. After each batch of materials is distributed, record it on the inventory card immediately and save the application form. When counting, it is used to check whether the release number of this batch of materials is consistent with the application form and the actual receipt number.
2) critical inventory method
Regularly check the key inventory methods of key materials stored and kept. At the beginning of July every year, the finance department, the warehouse keeper and the quality inspector make an inventory together. In inventory, we should first check the quality of inventory materials, and then determine the quantity, name and specification of materials, which is mainly used to grasp the changes of key materials in inventory, prevent and find errors in time, and fill in the inventory status checklist for reference and reference of relevant departments and general managers.
Periodic inventory method
At the beginning of each year (65438+ 10 month), the quality of inventory materials shall be comprehensively inspected and counted. In order to reduce the confusion and omissions in the inventory and make the inventory results accurate, it is necessary to close the warehouse and clean it up comprehensively. Therefore, it is required to make full preparations before the start of routine inventory work to ensure the smooth progress of inventory work.
The preparatory work before regular inventory mainly includes:
1。 Organization and training of personnel. Periodic inventory needs to establish a temporary joint organization with a certain form. Generally organized by warehouse supervisor, finance department, technology department, etc. Before taking stock, we should unify our understanding and methods to avoid human error.
1) Clean up the warehouse. Before the inventory, the warehouse materials shall be cleaned once, and the requirements are as follows:
* Materials that have not yet gone through warehousing formalities should be marked and not included in the inventory;
* The materials that have gone through the warehousing formalities should be distributed or identified as soon as possible, and are not included in the inventory;
* Arrange the palletizing, shelves and materials between them for statistical calculation;
* Check the measuring instrument and make adjustments to make it within the specified error range.
1。 Study and formulate the inventory workflow.
2。 The names, varieties and specifications of materials should be unified, and the units and methods of measurement should be unified to avoid the error of inventory results caused by inaccurate technical concepts and inconsistent measurement methods.
3。 Make an inventory.
