Description

Technical Field

[0001] The present disclosure relates to the field of goods sorting, and more particularly, to a goods sorting device having a planar turning type sorting module based on image processing. Background Art

[0002] Currently, automatic sorting devices are widely used in the manufacturing automation production line and the goods sorting line in the logistics industry. However, before sorting, all current automatic sorting devices must rearrange the goods to be sorted automatically or manually to ensure that the goods pass through the sorting device in a single-column arrangement. Otherwise, correct sorting cannot be achieved. This rearrangement process and the single-column sorting method greatly reduce the goods sorting speed. The sorting speed provided by the most advanced foreign automatic sorting devices can reach approximately 400 - 600 packages per minute depending on the specifications of the goods. Therefore, no matter how many such sorting devices are installed on a production line, the sorting speed of this production line can only reach 600 packages per minute at most because the sorting speed of the sorting device limits the transmission speed of the production line. Therefore, there is a need to improve the sorting speed of goods and the sorting efficiency of the sorting production line in the existing goods sorting devices. Summary of the Invention

[0003] In order to overcome the above problems and other technical problems to be solved, the present invention is made.

[0004] The purpose of the present disclosure is to provide an efficient goods sorting device that allows goods to be sorted quickly without affecting the conveyance of other goods. At the same time, the goods sorting device allows goods to be conveyed side by side without affecting the sorting of the goods.

[0005] According to the present disclosure, there is provided a goods sorting device, comprising:

[0006] At least one conveyor belt for conveying goods;

[0007] A scanning module, the scanning module including an image acquisition device for acquiring an image of the goods and a code scanning device for scanning goods conveyance information;

[0008] At least one sorting module, the sorting module being located behind the scanning module in the goods conveying direction, and the goods conveyed by the conveyor belt being conveyed to the sorting module, wherein each sorting module includes a plurality of sorting devices arranged side by side, each sorting device includes a plurality of steering mechanisms arranged side by side, each steering mechanism includes a steering mechanism bracket and a plurality of endless conveyor belts supported in the steering mechanism bracket, in the initial state of the steering mechanism the endless conveyor belts are arranged along the goods conveying direction, the endless conveyor belts can support the goods conveyed onto them and convey the goods in the horizontal direction, and the steering mechanism bracket can be controlled to rotate in the horizontal plane so that the endless conveyor belts arranged on the steering mechanism bracket rotate in the horizontal plane; and

[0009] A control unit, the control unit receiving and processing the goods image and the goods conveying information obtained by the scanning module, and determining the external features and sorting positions of the goods,

[0010] wherein each of the steering mechanisms can be individually controlled by the control unit so that the endless conveyor belts rotate independently in the horizontal plane,

[0011] wherein, when it is determined that the goods are to be sorted at the sorting module, the control unit determines the steering mechanisms involved in sorting the goods according to the external features of the goods, and controls the steering mechanisms involved in the plurality of steering mechanisms to turn from the goods conveying direction to the lateral direction when the goods pass by, so as to convey the goods to the sorting position, and

[0012] wherein, when it is determined that the goods are not to be sorted at the sorting module, the control unit controls the steering mechanisms not to perform steering, so that the endless conveyor belts horizontally convey the goods in the goods conveying direction to the next sorting position.

[0013] According to the present disclosure, the goods can be conveyed side by side on the sorting module without affecting sorting. Specifically, when the goods need to be sorted, the steering mechanisms involved in the sorting device turn to convey the goods to the sorting positions on both sides of the sorting device, while the goods arranged in parallel are conveyed normally, thus greatly improving the speed of goods sorting and conveying, and thereby overall improving the sorting speed.

[0014] Preferably, during the steering of the steering mechanism for sorting the goods, after the goods pass through the steering mechanism, the steering mechanism immediately returns to its initial state individually. Therefore, when the prior goods are sorted, the subsequent goods can be conveyed quickly and smoothly, thereby improving the conveying and sorting efficiency.

[0015] Preferably, each of the sorting modules includes at least four of the sorting devices, and each of the sorting devices includes at least four of the steering mechanisms. The number of the sorting devices and the steering mechanisms in each sorting device is not particularly limited, but can be determined according to the requirements of goods transportation.

[0020] Preferably, the two conveying devices are respectively arranged on two sides of the sorting module along a direction perpendicular to the goods conveying direction. The two conveying devices can relate to the same sorting position or two different sorting positions.

[0021] Preferably, an acceleration section or an accelerator is provided before the sorting module so as to form a specified interval between two adjacent goods in the front and back by accelerating the conveyor belt speed. Since there is a specified interval between two adjacent goods in the front and back, when the front goods are on the turned steering mechanism, the rear goods will not be on the same steering mechanism, thus not affecting the forward conveyance of the rear goods.

[0022] Preferably, the external features of the determined goods include the size of the goods and their positions on the conveyor belt. The control unit determines the steering mechanisms involved when the goods are sorted based on the size of the goods and their positions on the conveyor belt, and thus controls these steering mechanisms to perform steering actions.

[0023] Preferably, a plurality of sorting modules are provided, and only one scanning module is provided. That is, a single scan is performed before sorting the goods, and the controller controls each sorting module based on the conveying information and external features of all the goods obtained by the scanning module to sort all the goods to their respective sorting positions.

[0024] Preferably, a plurality of sorting modules are provided, and a scanning module is provided before each of the sorting modules. That is, before each sorting of the goods, the goods are scanned for information to re-determine the current position information and external features of the goods.

[0025] Preferably, another scanning module is provided after each of the sorting modules for checking the status of the goods after sorting.

[0026] Preferably, the scanning module is arranged above the conveyor belt via a bracket. The conveying position information of the goods can be located at any visible position. For example, the conveying position information of the goods is printed or pasted on the top of the goods, and the conveying position information of the goods can also be set on its left or right side. Preferably, an automatic flipping device can also be provided in the goods sorting device to turn the invisible label or position conveying information into visible information.

[0027] Preferably, the scanning module is arranged on the left or right side of the conveyor belt via a bracket, and the conveying position information of the goods is correspondingly printed or pasted on the left or right side of the goods, thereby enabling the scanning of the conveying position information of the goods.

[0028] Preferably, the scanning module is arranged above the conveyor belt via a bracket, and the scanning module is arranged to be programmable to move on the bracket. Thus, the scanning module can move to ensure accurate scanning of the conveying position information and external features of the goods.

[0029] Preferably, based on the conveying direction of the goods, each of the steering mechanisms can turn left or right at a predetermined angle. The predetermined angle is greater than 0 degrees and less than 90 degrees.

[0030] Preferably, the predetermined angle is variable during the turning of the steering mechanism, and the predetermined angle is determined by the control unit calculating the external features of the goods. That is, the control unit can control the steering mechanism to turn at a variable angle so that the goods can be conveyed to the conveying device along the expected route.

Detailed Description of the Specific Embodiments

[0039] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Before the description, it should be understood that the terms used in this specification and the appended claims should not be construed as being limited to the general and dictionary meanings, but should be interpreted based on the meanings and concepts corresponding to the technical aspects of the present disclosure, which are based on the principle that allows the inventor to appropriately define the terms for the best explanation.

[0040] In addition, the description presented here is only a preferred example for illustrative purposes and is not intended to limit the scope of the present disclosure. Therefore, it should be understood that other equivalent and modifications can be made thereto without departing from the spirit and scope of the present disclosure at the time of filing this application.

[0041] The goods sorting equipment of the present disclosure is used to sort a large number of goods and allows the goods to be conveyed side by side. Figure 1 It is an exemplary schematic diagram of the goods sorting equipment according to an embodiment of the present disclosure. Refer to Figure 1 , the goods sorting equipment 1 according to the present disclosure may include a first conveyor belt 10, a scanning module 20, a sorting module 30, a conveying device 40, a second conveyor belt 50, and a control unit 60. Each of the conveyor belts 10 and 50 may be a linear rolling conveyor belt, which is used to convey the goods 100 from the starting position to each sorting position. In Figure 1 only one sorting position is shown, however, according to the sorting requirements of the goods, the number of sorting positions may be multiple.

[0042] The scanning module 20 is used to perform image scanning on the goods 100 to obtain various information about the goods 100, such as conveying position information and the external features of the goods 100. To achieve the above functions, the scanning module 20 of the present disclosure includes an image acquisition device (such as a camera) and a code scanning device. Usually, the conveying position information about the goods 100 is printed or pasted on the top of the goods 100, therefore, the code scanning device of the scanning module 20 can obtain the conveying position information of the goods by scanning the two-dimensional code or bar code, and transmit the conveying position information to the control unit 60. However, the conveying position information of the goods may be located at any visible position. For example, the conveying position information of the goods may also be set on its left or right side. Preferably, an automatic flipping device may also be provided in the goods sorting equipment to convert the invisible label or position conveying information into visible. Further, the image acquisition device of the scanning module 20 performs image scanning on the goods 100, and transmits the obtained image to the control unit 60, so as to obtain the external features of the goods through the image, such as the size of the goods and its position on the conveyor belt.

[0043] In Figure 1 , a scanning module 20 is arranged above the first conveyor belt 10 via a bracket 201 and is located before the sorting module 30, so as to obtain the conveying information and size of the goods 100 before sorting the goods. However, the position and number of the scanning module 20 are not limited to the above situation. For example, the scanning module may be set on the left or right side, or may be set to be programmable to move. Further, another scanning module 20 may be provided after the sorting module 30, so as to correct the goods 100 after passing through the sorting module 30, for example, whether the qualified goods 100 have been sorted, whether the unsorted goods 100 are conveyed in the original position and state, etc. In addition, according to the requirements, a scanning module 20 may be provided for each sorting module 30.

[0044] Figure 2 An exemplary schematic diagram of a sorting module according to an embodiment of the present disclosure is shown. The sorting module 30 of the present disclosure is a programmable plane steering sorting module, which allows the qualified goods to be sorted and allows the unqualified goods to be continued to be transferred to the next conveyor belt. Figure 2 As shown in , the sorting module 30 according to the present disclosure can be composed of a plurality of sorting devices 31 arranged side by side. Each sorting device 31 has a substantially rectangular shape with the side surfaces standing upright. In the illustrated embodiment, a plurality of sorting devices 31 are arranged side by side in a direction perpendicular to the direction of cargo conveying. However, the present disclosure is not limited thereto, for example, a plurality of sorting devices 31 are arranged side by side in the direction of cargo conveying. Here, the number and size of the sorting devices 31 are determined according to cargo conveying requirements. Preferably, the sorting devices 31 can be made into standard modules with predetermined lengths and widths, and according to cargo conveying requirements, only an appropriate number of sorting devices 31 need to be provided. For example, Figure 2 It is shown that seven sorting devices 31 are arranged side by side.

[0045] Figure 3 1 shows an exemplary internal structure diagram of a sorting device of a sorting module according to an embodiment of the present disclosure. The sorting device 31 of the present disclosure may include a steering mechanism 310, an inner frame 311, a transmission motor 312, a transmission shaft 313, a transmission belt 314, and a rotating motor 315. For the sake of clarity, Figure 3 Only one steering mechanism is shown exemplarily. As shown in the figure, the steering mechanism 310 is arranged at the top of the inner frame 311. Specifically, the steering mechanism 310 includes a steering mechanism bracket 317 and a plurality of endless transmission belts supported in the steering mechanism bracket 317 via multiple pairs of rollers. The top surface of the endless transmission belt may be slightly higher than the top surface of the steering mechanism bracket 317 to facilitate the transmission of goods. The steering mechanism bracket 317 is supported on the top of the inner frame 311 by a steering bearing 316. The rotating motor 315 is configured to be able to drive the steering mechanism bracket 317 to rotate on a horizontal plane, thereby realizing the steering of the endless transmission belt arranged on the steering mechanism bracket 317 on a horizontal plane. In particular, the steering bearing 316 and the rotating motor 315 are coaxially arranged on the vertical rotating shaft at the lower part of the steering mechanism bracket 317.

[0046] At the same time, the plurality of pairs of rollers on which the endless transmission belt is arranged are driven by the transmission belt 314, so that the endless transmission belt is cyclically rotated to achieve horizontal transmission. The transmission belt 314 is drivably connected to the transmission motor 312 via the transmission shaft 313. Figure 3 As shown in the example, the transmission shaft 313 is arranged on the inner frame 311 along the horizontal direction, and a pulley for cooperating with the transmission belt 314 is arranged on the transmission shaft 313 .

[0047] With the above structure, the steering mechanism 310 of the present application can achieve steering on a horizontal plane while realizing the horizontal transmission of the endless transmission belt.

[0048] Figure 4 FIG. shows an exemplary internal structure diagram of a sorting device of a sorting module according to an embodiment of the present disclosure, in which five steering mechanisms are shown. The five steering mechanisms 310 are arranged linearly on the inner frame 311. In the present application, the number of the steering mechanisms 310 is not limited to five, but can be determined according to the requirements of goods transportation. These steering mechanisms 310 are respectively driven by separate rotating motors 315. That is, each steering mechanism 310 can independently perform steering. At the same time, the endless transmission belts of these steering mechanisms 310 are respectively driven by transmission belts 314. The transmission belt 314 of each steering mechanism 310 is drivably coupled to the transmission shaft 313. That is to say, each transmission belt 314 is drivably coupled to the transmission motor 312 via the transmission shaft 313, so that the endless transmission belts of all the steering mechanisms 310 are only driven by the transmission motor 312.

[0049] Further, referring to Figure 5 , the sorting device 31 of the present disclosure is provided with a generally rectangular outer frame 300. As Figure 4 shown, the inner frame 311 and the various components provided thereon are installed in the outer frame 300. The top of the outer frame 300 is provided with five circular openings for accommodating the five steering mechanisms 310. In Figure 5 the assembled state shown, the top surface of the steering mechanism bracket 317 is substantially flush with the top of the outer frame 300, and the endless transmission belt protrudes slightly from the top of the outer frame 300 to the outside for easy contact with the goods.

[0050] In addition, referring again to Figure 1 , two conveying devices 40 can be arranged on the left and right sides of the sorting module 30, that is, on both sides along the direction perpendicular to the goods conveying direction, so as to convey the sorted goods to the sorting position. Here, the two conveying devices 40 can relate to the same sorting position or two different sorting positions. That is to say, according to the goods conveying requirements, the two conveying devices 40 can convey the sorted goods to two different locations of the same sorting position, or can respectively direct the sorted goods to different sorting positions. As shown in the figure, the conveying device 40 can be a roller type conveying device including a group of rollers arranged side by side. Of course, the present invention is not limited thereto, and various improvements to the number, position and type of the conveying device should also fall within the scope of the present disclosure.

[0051] Hereinafter, the specific operation of the goods sorting equipment of the present disclosure will be described. Figures 6 - 9 is a schematic diagram of the operation process of the goods sorting equipment according to the present disclosure, in which Figure 6Shows a situation where two side-by-side goods are not sorted. Figures 7 - 8 Shows a situation where one of two side-by-side goods is sorted, and Figure 9 Shows a situation where both of two side-by-side goods are sorted.

[0052] The goods sorting device of the present disclosure allows goods to be conveyed side by side. Although the goods shown in the drawings are neatly arranged side by side on the conveyor belt, the goods conveyed side by side can also be staggered in the goods conveying direction. When sorting goods, the goods 100 (such as 100A, 100B, 100C, 100D, 100E, 100F) are first conveyed by the first conveyor belt 10 at the starting position. When the goods 100 pass through the position of the scanning module 20, the scanning module 20 acquires an image of the goods 100 and scans the information, and transmits the acquired image and scanning information to the control unit 60. The control unit 60 can determine the sorting position and size of the goods based on the acquired image and the scanned code information, and can determine whether the goods need to be sorted here according to the scanned code information.

[0053] As Figure 7 shown, when it is determined through the scanned code information that the goods 100A and 100B are not sorted here, the control unit 60 will not control the steering mechanism 310 of the sorting module 30 to make a steering action. Thus, the goods 100A and 100B will be conveyed to the second conveyor belt 50 through the endless conveyor belt of the steering mechanism 310.

[0054] Referring to Figure 8 , the goods 100C and 100D are conveyed side by side on the conveyor belt. When it is determined through the scanned code information that the goods 100C do not need to be sorted here, while the goods 100D need to be sorted here, the specified steering mechanism 310 is controlled according to the size and position of the goods 100D on the conveyor belt to make a steering action to convey the goods 100D to the conveying device 40. For example, the control unit 60 first determines the steering mechanism 310 involved when the goods 100D pass through the sorting module, and controls these steering mechanisms 310 to turn towards the conveying device 40 so that the goods 100D can be conveyed to the conveying device 40. Optionally, an additional conveyor belt can be provided at the end of the conveying device 40 to receive and continue to convey the goods sorted here.

[0055] Preferably, there is a certain interval between two adjacent goods before and after, and the interval is sufficient to ensure that when the goods in front are turned and conveyed by the turning mechanism 310, the goods behind that do not need to be sorted will not be turned and conveyed by the turning mechanism 310. Preferably, an acceleration section or an accelerator can be provided before the goods are conveyed to the first conveyor belt 10 to ensure the interval between two adjacent goods before and after by increasing the conveyor belt speed. In addition, the first conveyor belt 10 itself can also be used as an accelerator to ensure the above interval.

[0056] At the same time, since the turning mechanism 310 of the sorting module of the present disclosure can be turned independently, when two goods 100C and 100D are adjacent in the width direction of the conveyor belt, the sorting module 30 of the present disclosure can only turn the turning mechanism 310 involved in the goods 100D that require sorting, while maintaining the goods 100C that do not need to be sorted to continue to be conveyed along the goods conveying direction. Therefore, even when multiple goods are conveyed side by side, the sorting module 30 of the present disclosure can accurately sort the specified goods while maintaining the other goods to continue to be conveyed forward. Therefore, the present disclosure can allow the goods to be conveyed side by side, thereby maximizing the conveying and sorting efficiency of the goods.

[0057] In addition, each turning mechanism 310 is controlled such that when the goods that require sorting pass through the turning mechanism 310, the turning mechanism 310 is immediately restored to its initial position, so as not to affect the subsequent goods conveyance.

[0058] Figure 9 Shows the situation where two side-by-side goods are both sorted. As Figure 9 shown, when two side-by-side goods 100E and 100F are sorted simultaneously, the control unit 60 controls the specified turning mechanism 310 to make a turning action according to the sizes of the goods 100E and 100F and their positions on the conveyor belt, so as to turn the goods 100E and 100F to the conveying device 40 respectively.

[0059] In particular, in the present disclosure, each turning mechanism 310 can turn within a predetermined angle range based on the goods conveying direction. For example, based on the goods conveying direction, the turning mechanism 310 can turn left or right within the range of 0-90 degrees, so that the goods thereon can be conveyed left or right as needed to achieve the expected sorting.

[0060] Although the present disclosure has been described in conjunction with the above embodiments, the scope of the present disclosure is obviously not limited to the above embodiments. The specific components in the above embodiments of the present disclosure can be recombined to form new embodiments. Therefore, those skilled in the art will recognize that various variations, additions, and substitutions are possible without departing from the spirit and scope of the present disclosure as disclosed in the appended claims.
