[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0055] refer to Figures 1 to 3 This application provides a carton sorting device 10, which can automatically destacking and opening cartons 20, effectively improving the efficiency of carton sorting.

[0056] To facilitate a detailed description of the structure of the carton sorting equipment 10, the length direction X, width direction Y, and height direction Z of the carton sorting equipment 10 are defined here first, wherein the length direction X, width direction Y, and height direction Z are perpendicular to each other.

[0057] refer to Figure 2 , Figure 2 This illustration shows a cardboard box 20 to which the cardboard box sorting equipment 10 provided in this embodiment of the application is applicable. Specifically, during sealing, the cardboard box 20 is sealed using a first adhesive tape 21 (such as...). Figure 2 (as shown by the dashed line), second tape 22 (as shown by the dashed line) Figure 2 (as shown by the dashed line) and the third tape 23 (as shown by the dashed line) Figure 2 (As shown by the dashed line) The opening of the carton 20 is sealed. Specifically, the first tape 21 and the second tape 22 seal the carton 20 along the width direction K, and the third tape 23 seals the carton 20 along the length direction J. Furthermore, the first tape 21, the second tape 22, and the third tape 23 are arranged in an "I" shape. The carton sorting equipment 10 provided in this embodiment can automatically cut open the first tape 21, the second tape 22, and the third tape 23 to achieve automatic carton opening.

[0058] It should be noted that the cartons used in the carton sorting equipment 10 provided in this application embodiment are not limited to those in the following categories. Figure 2 The cardboard boxes shown are suitable for any cardboard boxes sealed with tape, and can be used with the cardboard box sorting equipment 10 provided in this application embodiment.

[0059] For example, refer to Figure 1 , Figure 3 and Figure 4 The carton sorting equipment 10 includes: a first conveyor line 100, a second conveyor line 200, a third conveyor line 300, a fourth conveyor line 400, and a fifth conveyor line 500. The first conveyor line 100 transports multiple stacked cartons 20 and performs destacking of the cartons 20, allowing individual cartons 20 to be transported to the second conveyor line 200 for opening. The third conveyor line 300 transports loose, individual cartons 20 to the second conveyor line 200. After opening, the cartons 20 enter the fourth conveyor line 400 via the second conveyor line 200. Workers on the fourth conveyor line 400 remove the necessary raw materials from the opened cartons 20 and place the empty cartons 20 on the fifth conveyor line 500. The fifth conveyor line 500 is used to collect and centrally process the empty cartons 20.

[0060] For example, in this embodiment, the first conveyor line 100, the second conveyor line 200, and the third conveyor line 300 are roller conveyors. However, this embodiment does not impose special limitations on this; for example, in other possible implementations, any one or more of the first conveyor line 100, the second conveyor line 200, and the third conveyor line 300 may also be belt conveyors, etc. In this embodiment, the fourth conveyor line 400 and the fifth conveyor line 500 are belt conveyors. However, this embodiment does not impose special limitations on this; for example, in other possible implementations, one or both of the fourth conveyor line 400 and the fifth conveyor line 500 may be roller conveyors, etc.

[0061] For example, refer to Figure 1 , Figure 3 and Figure 4 The first conveyor line 100 extends along the length direction X, and along the length direction X, the first conveyor line 100 has a first end 101 and a second end 102. The first conveyor line 100 is used to convey a plurality of stacked cartons 20 from the first end 101 to the second end 102 of the first conveyor line 100.

[0062] For example, the first conveyor line 100 further includes a first support 110, a handling mechanism 120, and a 3D camera 130. The first support 110 is located at the second end 102 of the first conveyor line 100. The 3D camera 130 is located on the first support 110, and is positioned above the first conveyor line 100 along the height direction Z, with its detection range capable of covering the stacked cardboard boxes 20. The handling mechanism 120 is movably connected to the first support 110 along the length direction X, width direction Y, and height direction Z, and is located above the first conveyor line 100.

[0063] The 3D camera 130 is used to acquire the dimensions of a single carton 20 along the length direction X, the width direction Y, and the height direction Z, as well as the specific position of the carton 20 relative to the first conveyor line 100 along the width direction Y and the length direction X, so that the handling mechanism 120 can transport the carton 20 to the first end 201 of the second conveyor line 200.

[0064] In some possible implementations, the stacked cartons 20 are placed in a pallet (not shown), and a first conveyor line 100 transports the pallet along the length direction X to achieve the transport of the stacked cartons 20 along the length direction X. The detection range of the 3D camera 130 is able to cover the entire pallet, so that the detection range of the 3D camera 130 can cover the stacked cartons 20.

[0065] For example, continue to refer to Figure 1 , Figure 3 and Figure 4 and combined Figure 2 The top of the first support 110 is provided with two first guide rails 111, a second guide rail 112, and a third guide rail 113. The first guide rail 111 extends along the length direction X, the second guide rail 112 extends along the width direction Y, and the third guide rail 113 extends along the height direction Z. The second guide rail 112 is movably connected to the first guide rail 111 along the length direction X, and the third guide rail 113 is movably connected to the second guide rail 112 along the width direction Y. The conveying mechanism 120 is movably connected to the third guide rail 113 along the height direction Z. Thus, the conveying mechanism 120 can move relative to the first conveyor line 100 along the length direction X, width direction Y, and height direction Z, thereby conveying any single carton 20 located on the first conveyor line 100 to the second conveyor line 200 for opening.

[0066] In this embodiment, the conveying mechanism 120 is a suction cup (not shown in the figure). The suction cup can adhere to the upper surface of the carton 20 to move the carton 20 along the length direction X, width direction Y, and height direction Z. However, this embodiment does not impose special restrictions on the specific type of the conveying mechanism 120. For example, in other possible implementations, the conveying mechanism 120 can also be a gripper mechanism, etc.

[0067] Continue to refer to Figure 1 , Figure 3 and Figure 4 and combined Figure 2 The second conveyor line 200 extends along the length direction X. The second conveyor line 200 has a first end 201 and a second end 202. Along the length direction X, the first end 201 of the second conveyor line 200 is closer to the first conveyor line 100 than the second end 202. And along the length direction X, the first end 201 of the second conveyor line 200 abuts against the second end 102 of the first conveyor line 100. Along the height direction Z, the second conveyor line 200 is higher than the first conveyor line 100 to prevent the carton 20 from being directly conveyed from the first conveyor line 100 to the second conveyor line 200. Exemplarily, along the height direction Z, the first end 201 of the second conveyor line 200 is located below the first support 110, so that the handling mechanism 120 can transport the carton 20 from the second end 102 of the first conveyor line 100 to the first end 201 of the second conveyor line 200.

[0068] refer to Figure 5 and combined Figures 1 to 4 For example, along the length direction X, the second conveyor line 200 includes a first marking position 221 and a second marking position 222, and the first marking position 221 and the second marking position 222 are spaced apart along the length direction X. Along the length direction X, the first marking position 221 is located between the second marking position 222 and the first end 201 of the second conveyor line 200.

[0069] The second conveyor line 200 further includes: two box-opening cutters 230 (specifically, box-opening cutter 230a and box-opening cutter 230b), two first positioning plates 240 (specifically, first positioning plate 240a and first positioning plate 240b), and two second positioning plates 250 (specifically, second positioning plate 250a and second positioning plate 250b). The first positioning plate 240a, the second positioning plate 250a, and the box-opening cutter 230a are located at the first box-marking position 221. The first positioning plate 240b, the second positioning plate 250b, and the box-opening cutter 230b are located at the second box-marking position 222.

[0070] For example, a first positioning plate 240a is disposed on one side of the second conveyor line 200 along the width direction Y, and a second positioning plate 250a is disposed on the other side of the second conveyor line 200 in a manner movable along the width direction Y. The first positioning plate 240a and the second positioning plate 250a are arranged opposite to each other along the width direction Y. Figure 5 As shown, the second positioning plate 250a can move along the width direction Y to the position shown by the second positioning plate 250a', so that the first positioning plate 240a and the second positioning plate 250a clamp the carton 20 along the width direction Y, so that the carton opening knife 230a can open the carton 20.

[0071] The second conveyor line 200 is also provided with a second support 210. The carton opening cutter 230a is connected to the second support 210 in a movable manner along the length direction X, the width direction Y and the height direction Z, so that the carton opening cutter 230a can move relative to the carton 20 along the length direction X, the width direction Y and the height direction Z to open the carton 20.

[0072] refer to Figure 6 and combined Figures 1 to 5 The box-opening tool 230a includes: a cutting edge 231, two auxiliary wheels 232, and a tool connecting part 233. The tool connecting part 233 is movably connected to the second bracket 210 in the length direction X, the width direction Y, and the height direction Z. The cutting edge 231 and the two auxiliary wheels 232 are connected to the tool connecting part 233, and the two auxiliary wheels 232 are rotatable relative to the tool connecting part 233.

[0073] For example, along the width direction U of the carton opener 230a, two auxiliary wheels 232 are located on opposite sides of the blade 231. The carton opener 230a applies tape (e.g., to the carton) to the carton 20. Figure 2 When the first tape 21, the second tape 22, or the third tape 23 shown is being cut, the auxiliary wheel 232 can roll along the upper surface of the carton 20 in the height direction Z, which guides the movement of the blade 231, prevents the blade from deviating, and makes the cutting smoother. The width direction U of the carton-opening blade 230a is perpendicular to the length direction V of the carton-opening blade 230a.

[0074] For example, a first positioning plate 240b is disposed on one side of the second conveyor line 200 along the width direction Y, and a second positioning plate 250b is disposed on the other side of the second conveyor line 200 in a manner movable along the width direction Y. The first positioning plate 240b and the second positioning plate 250b are disposed opposite each other along the width direction Y. The second positioning plate 250b is movable along the width direction Y so that the first positioning plate 240b and the second positioning plate 250b clamp the carton 20 along the width direction Y, so that the carton opening cutter 230b can open the carton 20.

[0075] The carton-opening cutter 230b is movably connected to the second bracket 210 in a manner that allows it to move relative to the carton 20 in the length direction X, width direction Y, and height direction Z, so as to open the carton 20.

[0076] The structure of the box opener 230b is the same as that of the box opener 230a described above. For a more detailed understanding, please refer to the specific description of the box opener 230a.

[0077] By way of example, in this embodiment of the application, the carton opening cutter 230a is used to open the carton 20 along the width direction Y, and the carton opening cutter 230b is used to open the carton 20 along the length direction X. (See reference) Figure 6 and combined Figure 5 The width direction U of the carton opening blade 230a is parallel to the length direction X of the carton sorting equipment 10, and the length direction V of the carton opening blade 230a is parallel to the width direction Y of the carton sorting equipment. The width direction U of the carton opening blade 230b is parallel to the width direction Y of the carton sorting equipment, and the length direction V of the carton opening blade 230b is parallel to the length direction X of the carton sorting equipment.

[0078] Specifically, when the conveying mechanism 120 transports the carton 20 from the second end 102 of the first conveyor line 100 to the first end 201 of the second conveyor line 200, the length direction J of the carton 20 is the same as the length direction X of the carton sorting device 10, and the width direction K of the carton 20 is the same as the width direction Y of the carton sorting device 10. In other words, at this time, the first tape 21 and the second tape 22 of the carton 20 extend along the width direction Y, and the third tape 23 extends along the length direction X. Then, under the drive of the second conveyor line 200, the carton 20 moves to the first cutting position 221. The opening cutter 230a moves to the position corresponding to the first tape 21 according to the dimensions of the carton 20 along the length direction X, width direction Y, and height direction Z obtained by the 3D camera 130, and cuts the first tape 21 along the width direction Y. Then it moves to the position corresponding to the second tape 22 and cuts the second tape 22 along the width direction Y. Afterwards, the carton 20, cut by the opening cutter 230a at the first cutting position 221, moves along the second conveyor line 200 to the second cutting position 222 under the transmission of the second conveyor line 200. The opening cutter 230b, based on the dimensions of the carton 20 along the length direction X, width direction Y, and height direction Z obtained by the 3D camera 130, moves to the position corresponding to the third tape 23 and cuts the third tape 23 along the length direction X. This completes the opening of the carton 20.

[0079] In this embodiment, a first cutting position 221 and a second cutting position 222 are provided. At the first cutting position 221, a cutting tool 230a cuts the first tape 21 and the second tape 22 of the carton 20. The carton 20 is then transported to the second cutting position 222, where a cutting tool 230b cuts the third tape 23 of the carton 20, thus opening the carton 20. In this process, the cutting tool 230a at the first cutting position 221 cuts only along the width direction (Y), and the cutting tool 230b at the second cutting position 222 cuts only along the length direction (X), effectively shortening the stroke of the two cutting tools 230. Therefore, through the synergistic effect of the first and second cutting positions 221, the opening speed of the carton 20 is improved.

[0080] It should be noted that in other possible implementations, the box cutter 230a may cut the first tape 21 and the second tape 22 along the length direction X, and the box cutter 230b may cut the third tape 23 along the width direction Y.

[0081] For example, in some possible implementations, the second conveyor line 200 is provided with only one carton cutting position, a first positioning plate 240, a second positioning plate 250 and a carton opening cutter 230. The carton opening cutter 230 is capable of cutting the third tape 23 of the carton 20 along the length direction X, and is capable of cutting the first tape 21 and the second tape 22 of the carton 20 along the width direction Y.

[0082] For example, continue to refer to Figure 1 , Figure 3 and Figure 4 and combined Figure 5 The fourth conveyor line 400 extends along the width direction Y and is located on one side of the second conveyor line 200 along the width direction Y. Along the length direction X, the fourth conveyor line 400 and the first conveyor line 100 are located at opposite ends of the second conveyor line 200.

[0083] Along the height direction Z, the fourth conveyor line 400 is higher than the second conveyor line 200. The second end 202 of the second conveyor line 200 is provided with a rotary lifting mechanism 260. Along the length direction X, the second slotting position 222 is located between the rotary lifting mechanism 260 and the first slotting position 221.

[0084] refer to Figure 7 and Figure 8 and combined Figure 1 , Figures 3 to 5The rotary lifting mechanism 260 has a support platform 261 for supporting the cardboard box 20 after it has been opened. The support platform 261 has a short side 262 and a long side 263. The long side 263 extends along the length direction of the rotary lifting mechanism 260, and the short side 262 extends along the width direction of the rotary lifting mechanism 260. The rotary lifting mechanism 260 is movable relative to the second conveyor line 200 along the height direction Z, and it is also rotatable relative to the second conveyor line 200.

[0085] Specifically, the rotary lifting mechanism 260 has a first state and a second state. In the first state, the support platform 261 of the rotary lifting mechanism 260 is flush with the second conveyor line 200, and the long side 263 is parallel to the length direction X (e.g., Figure 7 (As shown). In the second state, the support platform 261 of the rotary lifting mechanism 260 is flush with the fourth conveyor line 400, and the long side 263 is parallel to the width direction Y (as shown). Figure 8 (As shown).

[0086] For example, the surface of the support platform 261 of the rotary lifting mechanism 260 is provided with a conveyor belt, which in the second state is used to transport the carton 20 to the fourth conveyor line 400.

[0087] Specifically, after the carton 20 is opened at the second marking position 222, the rotary lifting mechanism 260 is in the first state. The opened carton 20 moves along the second conveyor line 200 to the support platform 261 of the rotary lifting mechanism 260. Then, the rotary lifting mechanism 260 moves along the height direction Z and rotates relative to the second conveyor line 200 to put the rotary lifting mechanism 260 into the second state. Then, the carton 20 moves along the width direction Y to the fourth conveyor line 400 under the action of the conveyor belt.
