The present invention relates to a warehouse management system for minimizing damages caused by a fall of a load due to an earthquake, and more particularly, to a warehouse management system including a function of controlling a loading position of a loading unit according to a weight and a size of a loaded article, It is possible to prevent the load part from being vibrated due to internal or external factors due to vibration or impact, particularly, an earthquake or the like, and to prevent any drop of the load placed on the load part by dropping the load due to the vibration of the load part The present invention relates to a warehouse management system capable of coping with an earthquake situation that reduces the risk of accidents that may occur and prevents or minimizes physical and personnel damage.

Generally, a warehouse is a distribution system of cargo carrying in, carrying out, and storing various types of cargo.

In a conventional warehouse, a storage shelf is provided in a row on a floor, and a conveyance means such as a stacker crane or a forklift truck (for example, a forklift) is disposed in a passage between the storage shelves to carry in and out freight.

The above-mentioned warehouses are provided with storage tanks which are storage shelves so that they can be stacked in multiple layers with a large amount of cargo for the purpose of enhancing the efficiency of the storage space of the cargo and facilitating the storage of the cargo. .

The cargo rack is constituted by a plurality of support frames vertically installed and a plurality of stacking frames horizontally provided in upper and lower layers between the support frames.

When the cargo is placed on a cargo mount having the above structure, the pallet or the cassette is lifted by a conveying means such as a stacker crane in a state where the cargo is supported on a pallet or a cassette, .

On the other hand, companies have been continuously increasing their interest in logistics in order to respond quickly to changes in complex and rapidly changing business environment. As a result, the logistics information management system for processing the logistics functions in a warehouse (WMS), Order Management System (OMS), and Transportation Management System (TMS).

Among these, Warehouse Management System (WMS) is a way to efficiently manage the entire process from inventory management to warehouse to warehouse and from warehouse to warehouse, which is the basis of logistics information management system.

The warehouse management system needs to manage various forms of products, types of packaging, and characteristics. It can inspect goods received in the goods receipt process, input information of goods, and store them on a location basis.

The received goods are moved within the location by the movement instruction, and it is desirable to minimize the movement lines in the warehouse.

An example of such a conventional reference management system is disclosed in Korean Patent Laid-Open Publication No. 10-2015-89794 (a method of supplementing a picking location in a warehouse management system), as shown in FIG. 1, A buffer zone in which the received goods are stored in a buffer zone, a picking zone in which the goods are supplemented according to a predetermined supplemental algorithm, and in which a product is picked according to an order, and a shipping center, Wherein the warehouse management system calculates a minimum standard quantity and a minimum expected sales quantity for each of the picking locations, and the warehouse management system counts the current quantity of each picking location, Generating a supplementary indication if the minimum quantity is less than the minimum quantity or the current quantity is less than the expected minimum quantity, A warehouse management system calculates a replenishment quantity, a warehouse management system calculates a replenishment unit when the replenishment quantity is determined, and a warehouse management system assigns a replenishment operation according to the replenishment quantity and the replenishment unit .

However, since the conventional warehouse management system is developed with an emphasis on an algorithm that can efficiently make goods receipt and warehousing, it is possible to reduce the number of internal , There is a limitation in that it is not possible to stably protect the loaded load from impact or vibration applied to the loading portion due to external factors.

That is, in the conventional warehouse management system, the warehouses are sequentially placed at random positions in the loading section according to the order in which the loads are loaded.

In this case, when the load is sequentially loaded on the loading unit regardless of the weight of the load, the center of gravity of the loading unit is moved upward from the lower end by the load scattered by the central heating on the loading unit, There is a structural problem in terms of safety which causes not only the damage of the load due to the fall of the load due to an enemy factor or an internal factor but also a problem that can lead to a human injury that may cause injury to the operator.

For example, when an external vibration or an impact, such as an earthquake, is applied to the loading section when a lightweight load is loaded at the lowest end with respect to one loading section and a load of a heavy load is loaded at the upper end, As the center of gravity is moved upward by the load placed on the loading section, the loading section is easily shaken even with a small shock or vibration, thereby causing physical and personal accidents that the load can not easily fall from the loading section.

Korean Patent Laid-Open Publication No. 10-2011-112001 (published on October 12, 2011) Korean Patent Publication No. 10-1416703 (Bulletin of Apr. 14, 2014) Korean Patent Publication No. 10-1666166 (issued October 24, 2016)

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

≪ Embodiment 1 >

The warehouse management system 1 of the first embodiment includes a measurement unit 10, an identification unit 20, a loading unit 30, and a vibration detection unit 40, as shown in Fig.

The measuring unit 10 measures the weight and size of the loaded object, and transmits information about the measured weight and size to the identifying unit 20.

In this case, the measuring unit 10 may be any device that can easily measure the weight and size of the load.

In addition, the measuring unit 10 may be configured to measure only the weight of the load and not measure the size. In the case of the production system of the production line, even if the measuring unit does not include a separate measuring unit, It is possible to omit the measuring unit 10 as the case may be.

The identification unit 20 acquires the measurement information provided to the measurement unit 10 and performs a function of assigning an identification number to the load carried together with the acquired information.

In addition, the identification unit 20 includes an input member 22 that allows an operator or an administrator to directly input additional information about the load.

The input member 22 is constituted by a touch screen or the like so that the operator or the manager can input additional information about the load such as the type of the load, the degree of handling required, the customer (or the place of delivery) .

In this case, the input member 22 may be configured to automatically input additional information about the load on the field by using a barcode or an RFID, etc., in which information about the load is input before the load is put on the load.

Of course, the present invention is not limited to this, and the input member 22 can be used as any means that can effectively, easily, and promptly input additional information about the load.

The identification unit 20 is provided with stability information such as a size and a danger level of the load according to the type of the load.

Such stability information, such as the danger level, is important information for selecting the position of the loaded load through the loading unit 30. [

For example, when handling is required such as glass, even if the weight of the load is relatively small compared to other loads, the load can be easily deviated from the loading portion 30 by an external factor or the like by inducing the load to be mounted on the lower end side rather than the upper end portion of the loading portion 30 So that breakage or damage can be minimized owing to the difference in height even when falling off.

The loading unit 30 loads the load through the measuring unit 10 and the identifying unit 20 by using a stacker crane or the like.

Further, since the loading section 30 is formed in the same or similar structure or configuration as the conventional one, the detailed description is omitted here.

In addition, the loading unit 30 includes a sensor 32 for detecting the empty space due to the loading and unloading through loading of the load.

When the load is loaded due to the loading of the load, the sensor 32 transmits the load position of the loaded load to the identification unit 20 so that the accurate position of the load can be confirmed through the identification unit 20 .

In addition, when the empty space is formed in the loading unit 30 due to the unloading of the load, the sensor 32 outputs a loading / unloading detection signal to the identification unit 20, which enables the loading of the load in the future, (20).

The vibration sensing part 40 performs a function of sensing vibrations or shocks acting on the space provided with each of the loading parts 30 or the loading part. In this case, the vibration sensing part 40 is configured in each of the mounting parts 30 so that an effective correspondence can be made according to vibrations or shocks acting on the mounting part 30. [

In addition, the vibration sensor unit 40 is connected to an earthquake prediction engine or the like, such as a weather station, to acquire earthquake information provided by the prediction engine. If the information is thus dangerous, To stop the loading of the load on the vehicle.

In addition, when the information acquired through the receiving unit 42 is dangerous, the vibration sensing unit 30 includes a speaker 44 so that a safety accident can be prevented from being alerted to a worker or an administrator .

In this case, the dangerous level is a danger level, which means that the load placed on the loading unit 30 can fall due to the degree of collapse or shaking due to vibration or impact acting on the loading unit 30 due to external or internal factors Information.

For example, in the case of the loading section 30 installed through the earthquake-resistant design, since the earthquake of the magnitude of 2 to 3 may not be greatly affected, warning broadcast or stop of operation is not performed through the speaker 44 On the contrary, in the case of the loading section 30 in which the earthquake-resistant design is not reflected, the load placed on the loading section 30 can be dropped even by an earthquake of the magnitude of 2 to 3 Therefore, warning broadcast and work stop are performed through the speaker 44 or the like. As described above, the setting range is differently applied according to the state of the loading unit 30. [

The operation state of the warehouse management system configured as above will be described with reference to FIG.

The warehouse management system is configured to determine whether there is a detection signal of the vibration sensing unit (S1), a receiving step (S2), a measuring step (S3), an identification number giving step (S4), a loading step (S5) And a sensing signal transmission step (S6).

Whether or not there is a detection signal of the vibration detection unit S1 determines whether vibration or the like is occurring in the loading unit 30 due to internal or external factors before starting the warehouse management system, 30), it is necessary to stop the work to prevent the occurrence of safety accidents.

In this case, the vibration sensing portion 40 senses the vibration acting on the loading portion 30 due to internal and external factors, and particularly makes it possible to prepare for an earthquake.

In addition, an earthquake is caused by the information provided by the prediction engine through the receiver 42 of the vibration detector 40.

The loudspeaker 44 of the vibration sensing unit 40 may be arranged at a risk level according to seismic information of the prediction engine received at the receiving unit 42 or vibration applied to the loading unit 30 through the vibration sensing unit 40, It is possible to minimize the occurrence of human casualties through personnel deployment while stopping the operation.

In the receiving step S2, when there is no detection of vibration in the loading unit 30 due to vibration, impact or the like due to internal or external factors through the vibration detecting unit 40, the load is loaded.

In addition, since the loading of the load is the same as or similar to that provided by the conventional warehouse management system, the detailed description will be omitted here.

The measurement step S3 measures the weight and size of the load through the measuring unit 10 when the loading of the load is performed.

In addition, the weight and size information measured through the measuring unit 10 is transmitted to the identification unit 20.

In the identification number assigning step S4, information on the weight and size measured through the measuring unit 10 and the like are received, and the additional information about the load is input directly or automatically through the input member 22 .

When the input of the measurement information and the additional information of the measuring unit 10 is completed, the identification unit 20 gives an identification number for the completed load.

In this case, the load shall be provided with an identification number including a classification code according to the risk level, together with weight, size and additional information.

When the input of the identification number is completed through the identification unit 20, the loading step S5 loads the load to the proper position of the loading unit 30 according to the identification number.

For example, as shown in FIG. 4, a relatively heavy material is stacked in two to three spaces from the bottom, and a heavy material is stacked in two or three spaces at the top of a heavy material, Allow the light weight to be loaded in the upper two or three spaces of the lightweight water.

Accordingly, the center of gravity of the loading unit 30 is positioned at the lower end by the heavy object, thereby preventing the loading unit 30 from being shaken due to vibration or impact acting on the inside or the outside. Accordingly, it is prevented that the load placed on the loading unit 30 falls easily in an environment such as a vibration or an impact, thereby preventing or minimizing the risk of physical and personal accidents.

In addition, the load having a high risk level among the loads loaded on the loading section 30 is loaded on the lower end portion, for example, a heavy load or a load position of a heavy load, based on safety information such as a risk grade, Even if the load of the danger class is dropped by the vibration of the loading unit 30, it is possible to minimize the damage or damage of the load by the drop height.

The loading unit 30 may be loaded in the same or similar manner as the conventional warehouse management system by using a stacker crane or the like, Any structure or configuration can be used so that the loading of the load can be easily carried out.

In the sensing signal transmission step S6 according to the loading, when a load is loaded on the loading unit 30, a sensing signal is generated by the sensor 32 formed in the loading space of the load, A signal is transmitted to the identification unit 20.

The identification unit 20 receives the sensing signal of the sensor 32 and adds the loading position number of the loading unit 30 according to the identification number assigned to the load or adds the loading position number to the loading position number Make sure the identification number of the load is displayed so that the goods can be shipped out smoothly in the future.

The above-described warehouse management system allows the stacking position of the stacking unit to be selectively performed according to the weight and size of the loaded stack, so that the center of gravity of the stacking unit is positioned downward, And particularly prevents or minimizes the shaking of the loading section due to the influence of an earthquake or the like.

In addition, the load can be rearranged at an arbitrary position according to the judgment of the manager. If the space is insufficient, the load is placed at an arbitrary position, and when the product is shipped, the load is automatically rearranged Function may be performed.

This prevents or minimizes the shaking of the loading portion, thereby preventing the load loaded on the loading portion from falling down, thereby preventing or minimizing physical and personnel damage.

In addition, when the detection signal of a dangerous level is input in the vibration sensor unit 40 during the loading process of the load, the operation is stopped and the damage of the person is prevented through the discharge of the personnel.

≪ Embodiment 2 >

The fixing pin 344 is formed at the center of the solenoid 342 and is transported by the magnetization of the solenoid 342 to fix the load placed in the loading space of the loading unit 30.

For example, the fixing pin 344 may be maintained at the initial backward position so as not to interfere with the loading space formed in the loading unit 30 so that the load can be loaded freely, and the solenoid 342, The pallet is temporarily inserted into the pallet positioned in the loading space of the loading unit 30 so that the pallet is temporarily fixed to the loading space.

In this case, the fixing member 34 is configured to be vertically erected, and as the fixing pin 344 is positioned upward in the vertical downward direction when fixing the pallet by advancing, Allow vibration to be interrupted.

The fixing member 34 is formed at the upper end of the fixing pin 344 so that when the fixing pin 344 is advanced to fix the pallet 34, a pressing force is applied to one end of the pallet 34, And a hook pin 346 for amplifying the clamping force.

The hook pin 346 is hinged by the fixing pin 344 and the hinge pin and rotates horizontally at right angles to the fixing pin 344 about the hinge pin so that a pressing force .

The operation state of the fixing member constructed as above will be described.

First, the detection signal is transmitted to the fixing member 34 when a detection signal indicating a dangerous level that the loading unit 30 can be vibrated due to an earthquake or the like is detected in the vibration detecting unit 40.

The hook pin 346 hinged to the one end by the hinge pin is moved out of the range of the solenoid 342 to the upper end of the fixing pin 344 and the hook pin 346 is inserted between the fixing pin 344 and the hook pin 346 The hook pin 346 is tilted in the horizontal direction with respect to the fixing pin 344 by the elastic action of the spring 348 constituted by the fixing pin 344.

The pallet positioned in the loading space of the loading unit 30 is fixed to the fixing pin 344 that has been advanced upward and the hook pin 346 So as to minimize the drop of the load on the vibrating loading part 30, thereby minimizing physical and personal damage.
