[0052] Please refer to Figure 1 , Figure 1 The overall flowchart of an automatic feeding method based on carton-packed tobacco provided by the embodiments of the present application is shown.

[0053] As Figure 1 shown, the automatic feeding method based on carton-packed tobacco can at least include the following steps:

[0054] Step 102: Determine the to-be-processed carton from at least two cartons in the material preparation area, and move the to-be-processed carton to the carton opening area.

[0055] In the embodiments of the present application, the automatic feeding method of the carton-packed tobacco can be applied to, but is not limited to, a robot or a control terminal corresponding to the robot. The robot or the control terminal corresponding to the robot can be respectively connected with a ground rail, a tape cutting device, a pneumatic cutting device, a visual positioning device and a suction cup grabbing device. The ground rail can be arranged in a tobacco conveying production line, which specifically includes a material preparation area, an unpacking area, a pneumatic cutting area and a feeding area (the robot can move to different areas according to the ground rail). The material preparation area can be used to place the tobacco after packaging, that is, the carton with a sealed plastic bag packed by the tape, and the sealed plastic bag contains tobacco. The unpacking area can be used to cut the carton by the tape cutting device to separate the carton and the sealed plastic bag containing tobacco. The pneumatic cutting area can be used to cut the sealed plastic bag containing tobacco by the pneumatic cutting device to separate the sealed plastic bag and the tobacco. After the sealed plastic bag and the tobacco are separated, the robot or the control terminal corresponding to the robot can transport the tobacco to the feeding area for subsequent feeding treatment by the feeding machine.

[0056] It can be understood that the visual positioning device mentioned above can be, but is not limited to, a shooting device to shoot the carton or the sealed plastic bag from different angles and can identify the shot image. The suction cup grabbing device mentioned above can be used to grab the top of the carton and transport the carton to the corresponding area with the movement of the robot. The tape cutting device mentioned above can be, but is not limited to, an electric cutting knife that can be controlled to move by the robot to cut the side tape and the bottom tape of the carton according to the instruction of the robot. The pneumatic cutting device mentioned above can be, but is not limited to, a pneumatic cutting knife that can be controlled to move by the robot to cut the top or the bottom of the sealed plastic bag according to the instruction of the robot.

[0057] Here, the tobacco conveying production line mentioned above can further include a carton collection area and a plastic bag collection area. The carton collection area can be used to collect the carton after the carton and the sealed plastic bag containing tobacco are separated. The plastic bag collection area can be used to collect the sealed plastic bag after the sealed plastic bag and the tobacco are separated.

[0058] Specifically, in the automatic feeding process of the tobacco, the carton to be processed can be determined in the material preparation area. The selection method of the carton to be processed can be, but is not limited to, combined with a preset selection path, for example, the first carton in the preset selection path can be selected as the carton to be processed. Or combined with the number of cartons contained in the tray area in the material preparation area, for example, a carton can be selected from the tray area with the most cartons as the carton to be processed. Here, it is not limited to this.

[0059] Further, after the to-be-processed carton is determined, a carton moving path can be generated according to the position of the to-be-processed carton and the position of the unpacking area, and the to-be-processed carton can be sucked to a specified position in the unpacking area according to the carton moving path.

[0060] As an option of the embodiment, the to-be-processed carton is determined from the at least two cartons in the material preparation area, including:

[0061] The at least two tray areas in the material preparation area are numbered and a carton suction path is planned according to a preset numbering order; wherein at least one tray area has at least two cartons placed therein.

[0062] The first carton in the carton suction path is taken as the to-be-processed carton, and a suction position is determined according to the upper surface area of the to-be-processed carton.

[0063] Specifically, in the process of determining the to-be-processed carton, all tray areas in the material preparation area can be numbered, wherein the material preparation area can be but is not limited to divided into multiple areas with consistent areas, and each area can be provided with a tray area for placing multiple cartons. Here, the numbering manner can be but is not limited to in a preset direction, for example, all tray areas in the first row are numbered from left to right, then all tray areas in the second row are numbered from left to right, and so on.

[0064] Then, after all tray areas are numbered, all cartons in the numbered tray areas can be planned according to a preset numbering order to generate a carton suction path. Taking the preset numbering order 12345 as an example, the tray areas corresponding to the numbers 12345 are determined first in the numbered tray areas, then one carton is selected from each of the tray areas numbered 1, 2, 3, 4 and 5 as a path carton, and the path formed by the five path cartons is taken as the carton suction path (the carton suction path passes through the tray areas numbered 1, 2, 3, 4 and 5 in turn).

[0065] Then, the first carton in the carton suction path can be taken as the to-be-processed carton to be processed, and the center area of the upper surface can be determined according to the upper surface area of the to-be-processed carton, and the center area is taken as the suction position of the to-be-processed carton, that is, the initial position in the above-mentioned carton moving path.

[0066] As another optional of the embodiment of the present application, the to-be-processed carton is moved to the unpacking area, comprising:

[0067] A carton moving path is generated based on the preset position of the unpacking area and the suction position;

[0068] The to-be-processed carton is moved to the unpacking area according to the carton moving path.

[0069] Specifically, in the process of moving the to-be-processed carton to the unpacking area, a corresponding carton moving path can be generated according to the preset position of the unpacking area and the suction position on the to-be-processed carton, combined with the historical path record. Here, it can be but not limited to judging whether there is a path containing the preset position of the unpacking area and the suction position on the to-be-processed carton in the historical path record. If there is, the path corresponding to the starting position of the suction position on the to-be-processed carton and the ending position of the preset position of the unpacking area in the path can be directly used as the carton moving path. If there is not, the path closest to the starting position of the suction position on the to-be-processed carton and the ending position of the preset position of the unpacking area in the historical path record can be determined, and the closest path is optimized to obtain the corresponding carton moving path. It can be understood that the above-mentioned preset position of the unpacking area can be the position for performing carton cutting processing, and a tape cutting device can be arranged around the position.

[0070] Step 104, identifying the to-be-processed carton, and performing carton cutting processing on the to-be-processed carton according to the identification result to obtain the sealed plastic bag in the to-be-processed carton.

[0071] Specifically, after the to-be-processed carton is moved to the unpacking area, the surface of the to-be-processed carton can be photographed by a visual positioning device, and then the photographed image is identified to identify the tape area on the surface of the to-be-processed carton. The tape cutting device can be controlled to cut the identified tape area to separate the to-be-processed carton and the sealed plastic bag.

[0072] As another optional of the embodiment of the present application, the to-be-processed carton is identified, and the to-be-processed carton is cut according to the identification result, comprising:

[0073] The tape area in the side image of the to-be-processed carton is identified, and the tape area at the lowermost end in the side image is determined;

[0074] The size parameter of the to-be-processed carton is obtained, and the corresponding carton thickness is determined according to the size parameter;

[0075] Based on any one vertex of the lowermost tape area and the carton thickness, a first cutting position is determined, and a first cutting path is planned based on the long side of the lowermost tape area.

[0076] According to the first cutting position and the first cutting path, the side cutting processing is performed on the to-be-processed carton.

[0077] Specifically, in the process of cutting the to-be-processed carton, the side of the to-be-processed carton can be first photographed by the visual positioning device to obtain two side images of the to-be-processed carton, and the adhesive tape area in each side image is identified to determine the adhesive tape area at the lowermost end in each side image. It can be understood that in the embodiment of the present application, the bottom adhesive tape of the to-be-processed carton is cut by using the gravity characteristics of the tobacco shreds, so that the sealed plastic bag falls into the material tray from the bottom opening of the to-be-processed carton.

[0078] Then, after determining the adhesive tape area at the lowermost end of the side of the to-be-processed carton, the size parameters corresponding to the to-be-processed carton can be measured, such as but not limited to including the length, width and height of the to-be-processed carton, and the carton thickness corresponding to the length, width or height of the to-be-processed carton can be determined in combination with the preset corresponding relationship. Here, the carton thickness corresponding to different sizes of cartons is different.

[0079] Then, after determining the carton thickness, the first cutting position can be determined according to any one vertex of the adhesive tape area at the lowermost end of the side of the to-be-processed carton and the carton thickness. Here, any one vertex of the adhesive tape area at the lowermost end of the side of the to-be-processed carton can be understood as any one bottom vertex of the side of the to-be-processed carton. The position with a distance from the bottom vertex being the sum of the carton thickness and the preset thickness can be but not limited to the first cutting position, that is, the horizontal coordinate of the first cutting position is consistent with the horizontal coordinate of the bottom vertex, and the difference between the vertical coordinate of the first cutting position and the vertical coordinate of the bottom vertex is the sum of the carton thickness and the preset thickness.

[0080] Then, the first cutting path can also be determined according to the length corresponding to the adhesive tape area at the lowermost end. The initial position of the first cutting path is the first cutting position mentioned above, the vertical coordinate of the terminal position can be consistent with the vertical coordinate of the first cutting position, and the difference between the horizontal coordinate of the terminal position and the horizontal coordinate of the first cutting position is the length corresponding to the adhesive tape area at the lowermost end.

[0081] Then, after determining the first cutting path, the adhesive tape cutting device can be controlled to cut the adhesive tape area at the lowermost end of the side of the to-be-processed carton according to the first cutting path.

[0082] As another optional of the embodiment of the present application, after the side cutting treatment of the to-be-processed carton according to the first cutting position and the first cutting path, the method further comprises:

[0083] performing adhesive tape recognition processing on the bottom image of the to-be-processed carton, and counting the number of recognized adhesive tape regions;

[0084] when it is detected that the number of all adhesive tape regions is two, generating a corresponding second cutting path based on each adhesive tape region;

[0085] performing bottom cutting treatment of the to-be-processed carton according to the second cutting path corresponding to each adhesive tape region;

[0086] when it is detected that the number of all adhesive tape regions exceeds two, determining a to-be-cut region according to all adhesive tape regions whose long sides are consistent with the long side length of the bottom image;

[0087] dividing the to-be-cut region into at least two sub-regions according to the preset wide side length, and determining a third cutting path according to the diagonal line of each sub-region; wherein the included angle between the diagonal lines corresponding to any two adjacent sub-regions is in a preset included angle interval;

[0088] performing bottom cutting treatment of the to-be-processed carton according to the third cutting path.

[0089] Specifically, after the side cutting treatment of the to-be-processed carton, the bottom image of the to-be-processed carton can be obtained by the visual positioning device to recognize the adhesive tape region from the bottom image, and the corresponding cutting treatment mode can be determined according to the number of all adhesive tape regions.

[0090] It can be understood that when it is detected that the number of all adhesive tape regions is two, it indicates that the bottom of the to-be-processed carton includes two mutually perpendicular adhesive tape regions, and one of the adhesive tape regions is used for sealing treatment of the bottom of the to-be-processed carton, and then the corresponding second cutting path can be generated according to each adhesive tape region, and each adhesive tape region can be cut according to the second cutting path, so that the bottom of the to-be-processed carton is cut open, that is, the sealed plastic bag falls off from the bottom of the to-be-processed carton.

[0091] When it is detected that the number of all adhesive tape regions exceeds two, it indicates that at least two adhesive tape regions are used for sealing treatment of the bottom of the to-be-processed carton, and then in order to improve the cutting efficiency of the adhesive tape, all adhesive tape regions whose long sides are consistent with the long side length of the bottom image can be used as the to-be-cut region.

[0092] Then, the to-be-cut region can be divided into at least two sub-regions according to the preset width length, each sub-region has a same area, and a third cutting path is determined according to a diagonal line of each sub-region, wherein the third cutting path can be a continuous cutting path, that is, in any two adjacent sub-regions, the end point of the former diagonal line is consistent with the start point of the latter diagonal line.

[0093] Then, each adhesive tape region can be cut according to the third cutting path, and the bottom of the to-be-processed carton can be cut, that is, the sealed plastic bag can be made to fall from the bottom of the to-be-processed carton.

[0094] Step 106, moving the sealed plastic bag to the pneumatic cutting area and cutting the sealed plastic bag to obtain the tobacco in the sealed plastic bag.

[0095] Specifically, after the to-be-processed carton and the sealed plastic bag are separated, the sealed plastic bag can be moved to the pneumatic cutting area, and the pneumatic cutting device is controlled to cut the sealed plastic bag to separate the sealed plastic bag and the tobacco. In the process of controlling the pneumatic cutting device to cut the sealed plastic bag, the bottom of the sealed plastic bag can be directly cut by the pneumatic cutting device after the bottom of the sealed plastic bag is recognized, so that the tobacco in the sealed plastic bag falls onto the tray after the bottom of the sealed plastic bag is cut; or the top of the sealed plastic bag can be cut by the pneumatic cutting device after the top of the sealed plastic bag is recognized, and the tobacco in the sealed plastic bag can be made to fall onto the tray from the top of the sealed plastic bag by turning over the sealed plastic bag.

[0096] As another optional embodiment of the present application, the cutting of the sealed plastic bag comprises:

[0097] The sealed plastic bag is fixed on both sides, and the top edge length and any one vertex of the top edge are recognized from the front view image of the sealed plastic bag.

[0098] Based on the preset plastic bag thickness and any one vertex of the top edge, a corresponding second cutting position is determined, and a fourth cutting path is planned based on the top edge length and the second cutting position.

[0099] According to the fourth cutting path, the top of the sealed plastic bag is cut by the pneumatic cutting device, and the sealed plastic bag is turned over so that the tobacco in the sealed plastic bag falls from the top of the sealed plastic bag.

[0100] Specifically, in the process of cutting the sealed plastic bag, the two sides of the sealed plastic bag can be fixed, for example, by extrusion or clamping, but the application is not limited thereto.

[0101] Next, the sealed plastic bag can be photographed by a visual positioning device to obtain a front view image, and the length of the top edge and any vertex of the top edge can be identified from the front view image. The second cutting position can be determined by combining the preset thickness of the plastic bag and the position of the vertex of the top edge. The horizontal coordinate of the second cutting position is consistent with that of the vertex of the top edge, and the difference between the vertical coordinates of the second cutting position and the vertex of the top edge is the preset thickness of the plastic bag.

[0102] Next, the fourth cutting path can also be determined according to the length of the top edge. The initial position of the fourth cutting path is the second cutting position mentioned above. The vertical coordinate of the terminal position can be consistent with that of the second cutting position, and the difference between the horizontal coordinates of the terminal position and the second cutting position is the length of the top edge.

[0103] Next, after the fourth cutting path is determined, the top of the sealed plastic bag can be cut according to the fourth cutting path by controlling the pneumatic cutting device, and the tobacco in the sealed plastic bag can be dropped from the top of the sealed plastic bag by flipping.

[0104] It can be understood that, by cutting the top of the sealed plastic bag, compared with cutting the bottom of the sealed plastic bag, the tobacco can be effectively protected from being cut during the cutting process, i.e., the tobacco is not cut by the pneumatic cutting device, thereby improving the overall processing efficiency and processing quality.

[0105] Step 108: delivering the tobacco in the sealed plastic bag to a feeder.

[0106] Specifically, after the tobacco in the sealed plastic bag is obtained by the tray, the weight of the tobacco in the sealed plastic bag can be measured. When it is detected that the weight of the tobacco in the sealed plastic bag reaches a preset weight range, it indicates that the tobacco in the sealed plastic bag is normal tobacco, and then the tobacco in the sealed plastic bag can be delivered to the feeder for subsequent processing procedures. It can be understood that when it is detected that the weight of the tobacco in the sealed plastic bag does not reach the preset weight range, it indicates that the tobacco in the sealed plastic bag is abnormal tobacco, and then the staff can be notified to timely investigate and process the tobacco in the sealed plastic bag.

[0107] Please refer to Figure 2 , Figure 2A structural schematic diagram of an automatic feeding device based on a carton-packed tobacco is shown.

[0108] As shown in Figure 2 The automatic feeding device based on a carton-packed tobacco can at least include a first processing module 201, a second processing module 202, a third processing module 203, and a tobacco conveying module 204, wherein:
