Abstract

PURPOSE: A warehouse operation system is provided to convey products, manufactured in a production field, at a specific position in a warehouse, and to withdraw the products from the warehouse for efficiently loading the products on a transport truck and managing the products at the warehouse. CONSTITUTION: The system comprises a position sensor, a height sensor, a PLC(Programmable Logic Controller), a weight sensor, a serial network/LAN converter, a push button sensor, a hub and a notebook. The position sensor senses a definite position at which the products are located, and the height sensor senses the height at which the products are located by calculating an RPM(Revolution Per Minute) of a motor installed within a crane. The PLC controls a work sequence and condition of a loading and unloading equipment. The serial network/LAN converter, installed between the serial network and the LAN, performs a data conversion when control instructions or sensed signals are transmitted between the notebook, and the PLC and the sensors.

Description

Warehouse management system {The system for manufacture-warehouse management}

The present invention relates to a system and apparatus for managing a product warehouse, and more particularly, to transfer a finished product produced on-site to a conveyor, and then store the transferred product at a specific location within the product warehouse, and from the specific location when the stored product is shipped. The present invention relates to a product warehouse management system and apparatus for efficient vehicle loading and product management for product transport vehicles to be sent to the outside.

In the commonly used product warehouse management, as shown in FIG. 1, when a product is produced, the produced product is transported to the conveyor 125, and the product is picked up by the crane coming to the conveyor 125, and then the product is The product is stored in the product warehouse by repeating the process of moving it to the place to be stored and putting it down again.When the stored product is shipped out of the factory, the crane moves to the stored product location and moves the product. Picking up and loading onto the external transport equipment 124 will be transported by the external transport equipment.

Referring to a hot rolling mill that produces a hot rolled coil 122 as an example of many product warehouses, as shown in FIG. The laser range finder 104 and the transverse laser range finder 105 are used. The driving range finder 104 corresponds to the reflecting reflector 120 for driving and the crane computer receives the corresponding distance value and displays it on the screen. The actual laser distance value is determined according to the installation position of the driving laser rangefinder 104 and the installation position of the driving reflector 120.

And the traversing laser rangefinder 105 is matched with the transverse reflecting plate 121 and the corresponding distance value is received by the crane computer and displayed on the screen. The actual laser distance value is the installation position of the driving laser rangefinder 105. And the installation position of the driving reflector 121.

The height meter typically checks the number of revolutions of the motor and detects the distance traveled by the encoder 108. The encoder controller 107 receives the measured value and sends it to the crane computer so that the crane computer receives the display on the screen. do.

Maintaining the accuracy of the product by using the measuring equipment as described above, which may require more information such as the weight or width of the product, where the weight is measured by the weighing unit 110 and the weight sensor 109 The crane computer is used for the crane in order to perform the work in the above method in which the measurement is performed and the width is measured and displayed on the screen in the same way as the height meter. Until now, only the equipment and the thermal network 113 have been used. .

In this case, the crane computer's load increased and there was no specific specification, so various communication methods were used, and management difficulties were scattered, and the stability of the system was not obtained.

Accordingly, in the present invention, it was conceived to eliminate various problems of product warehouse management as described above, by installing a serial / LAN converter on the measuring equipment, integrating all communications into the network, and then connecting the crane to the hub. The computer was completed as a technical task with the focus on increasing the stability of the system and the efficiency of product warehouse management by allowing all communication to be performed using only the network.
