Characteristics and innovative management of steel sheet stacking management in shipbuilding industry

Engineering industry, generally refers to the ship, steel structure, such as large-scale enterprises, some super-large shipyards, steel sheet stock reached 100,000, steel yard a total of hundreds of stacking, management of these steel plates, work mainly to take manual records and Excel to manage steel plate information, efficiency is not high.

Confusion is mainly manifested in the following aspects

A) Find board mainly rely on experience, move the stack, out of warehousing and other services must be manually recorded, then to the office input, there is lag, data can not be updated synchronously.

b) The historical data of each plate cannot be saved, and the quality traceability is difficult.

c) Various specifications of the steel plate mixed placement, the order of confusion, resulting in a heavy turnover of the board.

d) The physical inventory cycle is long, labor strong, accurate rate is not high

e) Some steel plate stacking time is too long, there is a phenomenon of rust

Steel plate is a special kind of material, compared with the supermarket commodity, the ship enterprise steel plate management is special in

(1) Inverted stack: steel plate overweight, large size, difficult to carry, the need for the crane electromagnetic suction cups, sometimes need to move the stack before the target plate pressure in the following out of the library;

(2) Side marking

Steel plate stacking storage, only from the side of the bar code identification, steel plate side roughness, rust and other factors, resulting in bar code label paste, antifouling and other problems are not solved.

(3) Stacking order

Ship enterprises on the fine management of steel plate, also requires the management of steel plate stacking number, stacking order (layer), easy to get out of the library, the system automatically find the top of the plate, reduce unnecessary move the stack operation.

(4) Accounting cost ration after the checkout

Ship enterprises in strict accordance with the project number (even the same type of ship, but also give the concept of the first ship, etc.) to calculate costs, out of the library of Steel, whether in the scope of the quota, only after the accounting, should be able to control costs in advance and in the matter.

These particulars determine the storage management of the steel plate, is different from the general goods warehouse management, management characteristics of the same time, but also to achieve the entire life cycle of steel plate, procurement, nesting, warehousing, picking list, hair materials, cutting, and other business is in a platform to achieve, enhance the overall interests of the company to obtain a better return on investment.

In this industry, colleagues in the field, have done some useful research, share the following

One, self-adhesive barcode label on the side of the steel plate adhesion problem

For the bar code label on the side of the problem of bad paste, the introduction of a new barcode label, suction is very solid, can be recycled, efficient and reliable, the technology applied for a patent, the introduction of large-scale production of patented products.

Plate identification, in the enterprise has a lot of effective methods, for example, with color code, different materials with different colors, the location and number of colors, representing the length, width, thickness.

This method of steel plate material types of enterprises, but in many materials, board rules up to more than 1000 kinds of ship enterprises can not be implemented.

Plate side uneven, very rough, self-adhesive barcode label is not easy to stick, lifting and handling easy to fall off, resulting in difficult to identify steel plate, seriously affecting work efficiency.

Most of the steel plate warehouse is outdoor, dust, wind and rain, steel plate side is certainly rusty, it is more difficult to stick on, some enterprises to spray paint on the plate to solve the rust problem, this method increases the cost, reduce the efficiency, also can not solve the plate side uneven, rough problem, or paste is not firm.

The innovative solution to this problem is the introduction of new barcode labels that allow stickers to be pasted on plastic bags instead of being pasted directly on the side of the rusty steel plate. You can paste the work at the yard site in advance in a clean office.

Barcode technology, you can use one-dimensional code, two-dimensional code and RFID electronic tags. Combined with the software, it can be reused completely without having to print the QR code repeatedly.

Second, the collection of steel plate stacking data collection and processing in a visual pad terminal

The above-mentioned new barcode label technology solves the problem of using bar code technology to identify the steel plate, and the steel yard is open-air, large area, warehousing and out of the library and other operations, often using a PDA to collect data, through the USB interface will be collected data into the PC-side processing, update warehousing data. In this process, the PDA just acts like a barcode gun to collect data in batches, unable to process the data in time (sometimes on-site query to a better target board, reduce the lifting, rapid decision-making).

The introduction of pad, Android operating system, has a good visual interface, you can see the steel yard of the aerial view, touch operation to select the query and select the board, out of the library information timely written to the database. Pad can integrate one-dimensional code, two-dimensional code scanning camera and RFID Reader module, is the pad-side directly out of the library screen, press the Library button, you can highlight the target board out of the library.
