Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo loading status detection system and a loading status detection method using the same,

The present invention relates to a loading status detection system for a cargo and a loading status detection method using the same. More particularly, the present invention relates to a loading status detection system used for detecting a loading status of cargo unloaded or loaded at a distribution center, The present invention relates to a method for detecting a stacking state.

The logistics center, which unloads or loads the logistics, introduces a technique for measuring the volume or size of the unloaded or loaded logistics for the automated processing of the logistics.

However, in the case of the technique of measuring volume and size of logistics applied so far, only technology for measuring the volume and size of the logistics in a state where a measuring device such as a scanner is fixed on a passage through which the logistics is moved is being developed, Korean Patent Application No. 2012-0138439 as a patent application.

However, in the case of the technologies that have been developed up to now, only the volume and the size of the logistics are measured in a state of passing through the predetermined docking part. Therefore, the volume and size of the logistics are measured in advance, There is a disadvantage that the state can not be grasped. Particularly, when a load failure or the like occurs in the loading of the logistics, the failure can be detected only when passing through the docking portion, so that the docking portion or the logistics can be damaged. To prevent this, Therefore, automation of the logistics center is greatly restricted.

In other words, until now, in the logistics center, the automation system is almost not realized in the situation where the manual work of the operator is required to solve the above-mentioned load defects. Accordingly, the workers are exposed to the risk of various safety accidents, There is an increasing need for a technology for an automation system of a distribution center that minimizes the occurrence of safety accidents of workers.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a system for detecting a load status of a cargo which can be effectively detected in a cargo loading status.

It is another object of the present invention to provide a method for detecting a load state using a loading state detection system for the cargo.

In order to achieve the object of the present invention, a cargo loading state detecting system according to an embodiment includes a loading unit, a detecting unit, and a transfer unit. The undercarriage extends in a first direction and forms a loading space on which a plurality of cargoes are stacked. The detecting unit scans the loading space based on the information on the loading space and the information on the loads to detect the loading state of the loads and whether the loading of the loads is faulty. The conveying unit conveys the cargoes when it is determined that the loading state of the cargoes is good in the detecting unit.

In one embodiment, the detection unit may include first and second frames extending in a second direction perpendicular to the first direction at each of opposite corners of the undercarriage, first and second frames extending in a second direction perpendicular to the first direction, And first and second scanners that are transported in the second direction on the first and second guides and that scan the loading space, respectively.

In one embodiment, the first scanner and the second scanner may be positioned diagonally across the loading space.

In one embodiment, the detection unit includes a pair of first and second horizontal frames extending in the first direction at an upper portion of the inferior portion, a pair of first and second horizontal frames extending in the first direction along the first and second horizontal frames, And first and second scanners fixed to both ends of the moving frame to scan the loading space as the moving frame is moved in the first direction.

In one embodiment, the first scanner scans a space adjacent to the first scanner in the loading space, and the second scanner scans a space in the loading space adjacent to the second scanner, The data scanned by the two scanners may be merged to detect the loading state of the loading space.

According to another aspect of the present invention, there is provided a method for detecting a load state, the method comprising: receiving information about a loading space formed on an upper portion of a loading unit extending in a first direction; And unloads the cargoes into the loading space. The loading space is scanned. And merges the scanned data. Based on the merged data, it is judged whether the cargoes are loaded or not.

In one embodiment, the information about the loading space includes information about the volume of the loading space, the information about the loads includes information about the volume or size of each of the loads, The loading defect area can be set based on the information and the information about the cargoes.

In one embodiment, the number and the loading state of the cargoes stored in the loading space can be predicted from information on the volume or size of each cargo.

In one embodiment, in scanning the loading space, first and second scanners positioned to face each other diagonally across the loading space move in a second direction perpendicular to the first direction, Space can be scanned.

In one embodiment, in scanning the loading space, first and second scanners located at both ends of the moving frame moving in the first direction at the top of the loading space may scan the loading space.

In one embodiment, merging the scanned data comprises removing noise in the data scanned by the first and second scanners, equalizing the noise canceled data, and equalizing And coinciding the coordinate systems of the data with each other.

According to the embodiments of the present invention, the detecting unit detects the loading state and loading defect in a state in which the information on the loading space and the information on the cargo are inputted in advance, and in particular, from the information on the loading space, And when the stacking state exceeding the threshold value is detected, it can be detected as a stacking failure, so that it is possible to more effectively detect the stacking state and the stacking failure.

Also, based on the information about the cargoes, it is possible to detect the number of cargoes and the loading status from the detection information detected in the loading space, which is effective for automating the transportation of the goods.

In addition, since the detecting unit includes the scanners that move in the up-and-down direction at the diagonal edge with the loading space therebetween and scan the loading space, the loading status and the loading error of the loads located in the relatively large loading space can be relatively simple .

Alternatively, the detecting unit may include scanners moving in the horizontal direction at the upper portion of the loading space and scanning the loading space, so that the loading status and loading failure of the loads located in a relatively large loading space can be relatively simple .

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

1 is a perspective view illustrating a cargo loading state detection system according to an embodiment of the present invention.

Referring to FIG. 1, a cargo loading state detection system 10 according to the present embodiment includes a loading unit 100, a detection unit 200, and a transfer unit 400.

The loading unit 100 forms a loading space 102 on an upper part of the space where the cargo 110 transported by the freight car or the like is loaded and the cargoes 110 are located in the loading space 102.

The loading unit 100 includes a loading plate 101 on which the cargo 110 is placed and when the loading plate 101 has a rectangular shape, And may be formed in a rectangular parallelepiped shape at a predetermined height.

The unloading portion 100 extends in a first direction X and the transferring portion 400 extends from the unloading portion 100 and extends in the first direction. In addition, the unloading unit 100 may include a conveying device such as a conveyor belt, and the cargo 110 unloaded from the unloading unit 100 may be transferred to the transferring unit 400.

Each of the cargoes 110 unloaded to the unloading unit 100 may have a rectangular parallelepiped shape, for example, a box. Thus, the cargoes 110 loaded in the loading space 102 are arranged such that a plurality of boxes, such as the first, second, and third cargoes 111, 112, and 113, .

The detecting unit 200 includes a first frame 210 and a second frame 220, and may further include a third frame 230 as needed.

The first to third frames 210, 220 and 230 extend in a second direction Y perpendicular to the first direction X and are fixed to the four corners of the loading plate 101 . In this case, the first and second frames 210 and 220 are fixed to the corners of both ends along the first direction X, which is the extending direction of the loading plate 101, so as to face diagonally with each other.

At this time, the third frame 230 may be fixed to any one of the remaining corners where the first and second frames 210 and 220 are not fixed. Although not shown, May be further secured to the other non-fixed edge.

A first guide 211 is formed on the first frame 210 along the second direction Y and a second guide 221 is formed on the second frame 220 along the second direction Y. [ .

Thus, the first scanner 212 is moved on the first guide 211, and the second scanner 221 is moved on the second guide 221. In this case, the first scanner 212 and the second scanner 221 are synchronized with each other and move along the first and second guides 211 and 221 in the second direction, To scan the cargoes 110 loaded on the vehicle.

In this case, since the first scanner 212 and the second scanner 221 are located at the diagonal corners of both ends with respect to the loading space 102, the first scanner 212 can be moved from one side edge The second scanner 222 scans the second scanning area 223 from the other side edge to the center of the stacking space 102 Scanning.

At this time, an area scanned by the first and second scanners 212 and 221 may occur, which may be processed through a data merge step described later.

As described above, the first and second scanners 212 and 221 are synchronized with each other and moved in the second direction Y to scan the loading space 102, It is determined whether or not the loading status of the cargoes 110 is good.

When the loading status of the cargoes 110 is judged to be good, the cargoes 110 are transferred to the transfer unit 400, and when the loading status is judged to be bad, And transfers the cargoes (110) to the transfer unit (400).

As described above, the transfer unit 400 extends along the first direction X and transfers the cargoes 110 when it is determined that the loading state of the detecting unit 200 is good.

2 is a perspective view showing a cargo loading state detecting system according to another embodiment of the present invention.

The cargo loading state detection system 20 according to the present embodiment is substantially the same as the cargo loading state detection system 10 described with reference to Fig. 1 except for the configuration of the detection unit 300, And the description thereof will be omitted.

Referring to FIG. 2, in the stacking state detecting system 20 according to the present embodiment, the detecting unit 300 includes a plurality of detectors 300 disposed at four corners of the loading plate 101 and extending in the second direction Y, 1 to 4 < th > frames 310, 320, 330, and 340, respectively.

The detecting unit 300 includes a first horizontal frame 350 connecting the upper ends of the first and third frames 310 and 330 to each other and extending in the first direction X, And a second horizontal frame 360 connecting the upper ends of the fourth frames 320 and 340 to each other and extending in the first direction X. [

Further, the detecting unit 300 further includes a moving frame 370 guided by the first and second horizontal frames 350 and 360 and moved along the first direction X, First and second scanners 371 and 372 are fixed to both ends of the frame 370.

Thus, the first and second scanners 371 and 372 move along the first direction X, and the loading space 102 scans the loading status of the cargoes and the loading defect.

In this case, the first scanner 371 is positioned at one end of the moving frame 370, so that the first scanning area 373, which is an area of the loading space 102 close to the first scanner 371, And the second scanner 372 is positioned at the other end of the moving frame 370 so that the second scanning area 374 which is an area of the loading space 102 close to the second scanner 372 is scanned .

After the stacking space 102 is divided and scanned by the first and second scanners 371 and 372, the data scanned by the data merging described later is merged into the stacking space 102, The loading state can be detected. In addition, if the scanned data are overlapped with each other, noise may be removed through the data merging.

Fig. 3 is a flowchart showing a loading status detection method using the loading status detection system of Fig. 1 or Fig. 4 is a flow chart illustrating the step of merging the scanned data of FIG. 5A and 5B are examples showing the results of detecting the loading state of the cargo through the loading state detection method of FIG.

The above-described stacking state detection system of FIG. 1 and FIG. 2 is the same as that for detecting the stacking state of the stacking space 102 by dividing and scanning the stacking space 102 requiring scanning only with different positions of the scanners . Therefore, the load state detection method using the load state detection system of Figs. 1 and 2 will be described below.

Referring to FIG. 3, in the loading state detecting method, information about the loading space 102 and the cargoes 110 is input (step S10).

The information about the loading space 102 includes information about the volume of the loading space 102 and may include information about a coordinate value for the loading space 102 for this purpose. Since the volume information is included in the information on the loading space 102, it is possible to set a threshold value that is out of the range of the loading space 102, and the threshold value is set as information on the coordinate value .

For example, in FIGS. 5A and 5B, the area indicated by the rectangle of the blue gamut of the left side and the area indicated by the rectangle of the green series on the right side may be combined and provided as information on the loading space 102, , And can be displayed as an area based on information on the coordinate values as shown in the figure.

On the other hand, the information on the cargoes 110 includes information on the volume or size of each cargo. In this case, if there are various types of cargoes loaded into the loading space 102, information on the volume or size of each cargo may be included.

When the information about the volume or size of the cargoes 110 is input in advance, the number and the load status of the cargoes stored in the loading space 102 before the detection of the detection unit 200 is determined in advance Therefore, it is possible to more easily grasp whether or not the loading defect is detected from the detection result of the detection unit 200. [

For example, if the volume of the cargo is large enough to be loaded in the loading space 102, only the loading state of the one cargo is grasped based on the detection result of the detecting unit 200, If the volume of the cargo is relatively small and a plurality of cargoes are stacked on the loading space 102, the cargo can be loaded on the cargo based on the loading state of the cargo based on the detection result of the detecting unit 200 The number of sensors and the like can be detected at the same time.

Thereafter, the cargoes 110 are unloaded into the loading space 102 (step S20).

Thereafter, when the cargo 110 is unloaded, the loading space 102 is scanned through the scanners of the detecting unit 200 (step S30).

In this case, in the embodiment shown in FIG. 1, the first and second scanners 212 and 222 reciprocate in the second direction with diagonally facing each other, and the first and second scanning areas 213 and 223 In the embodiment shown in FIG. 2, the first and second scanners 371 and 372 are reciprocated in accordance with the movement of the moving frame 370 in the first direction, Scanning areas 373 and 374 are scanned.

Thereafter, the scanned data are merged by the first and second scanners (step S40).

More specifically, referring to FIG. 4, in the step of merging the scanned data (step S40), noise is first removed from data scanned by the first and second scanners, respectively (step S41) .

That is, the scanned data requires continuous data to be derived when considering the loading state of the cargoes 110 with respect to the outline of the cargoes 110. Therefore, And remove it.

In addition, the first and second scanners scan the first and second scanning areas, respectively, and the first and second scanning areas all correspond to the inside of the loading space. Thus, among the scanned data Data excessively deviating from the range defined by the loading space 102 is regarded as noise and removed.

Thereafter, the noise-removed data is equalized (step S42). Data scanned by the first and second scanners may include data of different characteristics even if the noise is removed, so that data is equalized through predetermined filtering (e.g., low pass filtering).

Thereafter, the coordinate systems of the equalized data are matched with each other (step S43). Thus, the data scanned by the first and second scanners, respectively, are represented by one coordinate system, in which case the overlapping coordinates are eliminated.

As described above, when the merging step of the data scanned by the first and second scanners is finished, for example, the merged data is displayed as indicated by points in FIG. 5A or 5B .

Thereafter, it is determined whether or not the loading is defective (step S50).

Specifically, if the loading space 102 is displayed as an area on the coordinate, based on the information about the loading space 102, the area indicated by the loading space 102, It is possible to determine whether the cargoes are stacked or not.

5A, when it is determined that the cargoes 110 are located inside the area indicated by the loading space 102, it is determined that the cargoes 110 are in a good condition, And is transported through the transport unit 400 (step S70).

On the other hand, if it is determined that the cargoes 110 are located outside the area indicated by the loading space 102, that is, outside the area set as the threshold value, as shown in FIG. 5B, The defective elements at the time of loading the cargoes 110 are removed (step S60), and the scanning step for the loading space (step S30) is performed again.

According to the embodiments of the present invention, the detecting unit detects the loading state and loading defect in a state in which the information on the loading space and the information on the cargo are inputted in advance, and in particular, from the information on the loading space, And when the stacking state exceeding the threshold value is detected, it can be detected as a stacking failure, so that it is possible to more effectively detect the stacking state and the stacking failure.

Also, based on the information about the cargoes, it is possible to detect the number of cargoes and the loading status from the detection information detected in the loading space, which is effective for automating the transportation of the goods.

In addition, since the detecting unit includes the scanners that move in the up-and-down direction at the diagonal edge with the loading space therebetween and scan the loading space, the loading status and the loading error of the loads located in the relatively large loading space can be relatively simple .

Alternatively, the detecting unit may include scanners moving in the horizontal direction at the upper portion of the loading space and scanning the loading space, so that the loading status and loading failure of the loads located in a relatively large loading space can be relatively simple .

In this case, the data scanned by the scanners are combined with each other through noise elimination, equalization, and coordinate system matching, so that it is possible to automatically determine the loading state and loading defect of the cargoes while using a relatively small number of scanners .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.

The loading status detection system and the loading status detection method using the same according to the present invention have industrial applicability that can be used in a distribution center where cargo is loaded or unloaded.
