[0036] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0037] Please see Figure 1 , Figure 3 , Figure 5 , Figure 8This application discloses a carton depalletizer, comprising: at least one feeding conveyor 1; a robotic arm 2, the robotic arm 2 being equipped with a material handling mechanism 3; and at least one depalletizing device 4, the depalletizing device 4 comprising a frame 41, a buffer mechanism 42 disposed on the frame 41, an edge-blocking mechanism 43, and a turning mechanism 44. The buffer mechanism 42 comprises a buffer roller line 421, a blocking assembly 422, and a roller assembly 423 located at the end of the buffer roller line 421 along a first conveying direction. The conveying speed of the roller assembly 423 is greater than that of the buffer roller line 421. The conveying speed of 1, the edge-adjusting mechanism 43 includes an edge-adjusting roller line 431 and a lifting assembly 432. The edge-adjusting roller line 431 receives the carton 5 conveyed by the roller assembly 423 and conveys it along the second conveying direction, which is perpendicular to the first conveying direction. Both the edge-adjusting roller line 431 and the lifting assembly 432 are inclined. The turning mechanism 44 includes a turning roller line 441 and a turning assembly 442. The turning roller line 441 is connected to the edge-adjusting roller line 431. The conveying speed of the turning roller line 441 is greater than the conveying speed of the edge-adjusting roller line 431.

[0038] For ease of explanation, Figure 1 The first conveying direction and the second conveying direction are marked in the figure. The first conveying direction is the X-axis direction in the figure, and the second conveying direction is the Y-axis direction in the figure.

[0039] Preferably, there are two feeding conveyor mechanisms 1, which facilitates the simultaneous transport of two product carton stacks 6. Preferably, the feeding conveyor mechanism 1 is a chain conveyor.

[0040] Please see Figure 2 The preferred material handling mechanism 3 includes a connecting flange 31, a mounting plate 32 fixedly connected to the connecting flange 31, and a plurality of suction cups 33 disposed on the mounting plate 32. The connecting flange 31 is fixedly connected to the robot arm 2.

[0041] Please see Figure 3 The buffer roller line 421 is connected to and driven by the first motor 424. The roller assembly 423 includes a plurality of rubber-coated rollers 4231 arranged along the first conveying direction. The plurality of rubber-coated rollers 4231 are connected to and driven by the second motor 4232. The rotational speed of the second motor 4232 is greater than that of the first motor 424.

[0042] To prevent the carton 5 from sliding off the buffer roller line 421, a protective plate 425 is provided at the beginning of the buffer roller line 421.

[0043] Please see Figure 4 The blocking assembly 422 includes a blocking bracket 4221, a blocking cylinder 4222 disposed on the blocking bracket 4221, and a blocking plate 4223 connected to the blocking cylinder 4222. The blocking cylinder 4222 is activated to raise or lower the blocking plate 4223.

[0044] Specifically, along the first conveying direction, there are four of the multiple coated rollers 4231 in each column. When the carton 5 moves from the first two coated rollers 4231 to the last two coated rollers 4231, the baffle plate 4223 is raised. The baffle plate 4223 is located between the first two coated rollers 4231 and the last two coated rollers 4231, blocking the carton behind.

[0045] Please see Figure 6 The lifting assembly 432 includes a fixed frame 4321, a mounting frame 4322 disposed on the fixed frame 4321, a plurality of lifting rollers 4323 disposed on the mounting frame 4322, and a lifting cylinder 4324 connected to the mounting frame 4322. By tilting the fixed frame 4321, the plurality of lifting rollers 4323 can be arranged at an angle. Along the second conveying direction, the plurality of lifting rollers 4323 are arranged in multiple rows, and the plurality of lifting rollers in each row are spaced apart along the tilting direction.

[0046] For improved lifting stability, please refer to [link / reference]. Figure 7 Preferably, a linear bearing 4325 is provided on the fixed frame 4321, and a guide rod 4326 is connected to the mounting frame 4322, with the guide rod 4326 extending into the linear bearing 4325. The lifting cylinder 4324 drives the mounting frame 4322 to move vertically, and the mounting frame 4322 drives the guide rod 4326 to move linearly along the linear bearing 4325.

[0047] To facilitate the positioning of the carton 5, it is preferable to provide a limiting plate 433 above the inclined side of the edge roller line 431.

[0048] Please see Figure 9 , Figure 10 The steering assembly 442 includes a bogie 4421, a servo motor 4422 mounted on the bogie 4421, a driving synchronous pulley 4423 and a driven synchronous pulley 4424, a synchronous belt 4425 connecting the driving synchronous pulley 4423 and the driven synchronous pulley 4424, and a steering plate 4426 that moves synchronously with the synchronous belt 4425. The movement of the synchronous belt 4425 drives the movement of the steering plate 4426, facilitating the adjustment of the position of the steering plate 4426, i.e., adjusting the steering stop position. This allows cartons that need to be turned to turn, while cartons that do not need to be turned are not blocked and are directly conveyed out along the steering roller line 441.

[0049] The steering plate 4426 includes a vertical rod 44261, a first guide plate 44262 and a second guide plate 44263 connected to the vertical rod 44261. Both the first guide plate 44262 and the second guide plate 44263 extend along a second conveying direction. Preferably, the vertical rod 44261 is connected to a first clamping plate 44264, and a second clamping plate 44265 is disposed above the first clamping plate 44264. The timing belt 4425 passes between the first clamping plate 44264 and the second clamping plate 44265. Locking the first clamping plate 44264 and the second clamping plate 44265 together can drive the timing belt 4425 to move.

[0050] In order to facilitate the movement of the carton 5 to the first guide plate 44262 so as to stop and turn when it hits the upright 44261, the front end of the first guide plate 44262 is preferably set in an arc shape.

[0051] Please see Figure 8 , Figure 11 The end of the steering roller line 441 is provided with a stop assembly 443. The stop assembly 443 includes a stop fixing frame 4431, a stop cylinder 4432 disposed on the stop fixing frame 4431, and a stop plate 4433 connected to the stop cylinder 4432.

[0052] In use, the product carton stack 6 is transported to the robotic arm 2's suction station via the feeding conveyor 1. Multiple suction cups 33 then pick up one layer of cartons and place them on the buffer roller conveyor 421. (See also...) Figure 12 When a carton 5 reaches the rubber-coated roller 4231, its increased speed creates distance between it and the slower-moving cartons 5 behind it. At this point, the blocking cylinder 4222 rises to block the slower cartons. When the faster-moving cartons 5 reach the edge roller line 431, the lifting roller 4323 is lifted by the lifting cylinder 4324. Due to inertia, the cartons 5 slide on the lifting roller 4323 until they reach the limit plate 433. Then, the lifting roller 4323 descends, and the cartons 5 fall onto the edge roller line 431. Please refer to [link to relevant documentation]. Figure 13 The side roller conveyor 431 transports the carton 5 to the deflector roller conveyor 441. Because the deflector roller conveyor 441 and the side roller conveyor 431 have a speed difference, the carton 5 on the deflector roller conveyor 441 moves faster, increasing the distance between it and the slower carton 5 on the following side roller conveyor 431. Please refer to [link / reference needed]. Figure 14 To facilitate subsequent turning, when the narrow side of carton 5 faces forward, it will not hit the upright 44261 and will be directly conveyed forward along the turning roller line 441. When the long side of carton 5 faces forward, it will hit the upright 44261 after passing the first guide plate 44262 and be stopped and turned by the upright 44261, so that the narrow side of carton 5 faces forward. Please refer to [link / reference]. Figure 15This facilitates subsequent scanning of the barcode on the narrow side. The carton 5 is conveyed out by the turning roller line 441 along the second guide plate 44263 and transported to the manual palletizing end. The empty pallet 7 is transported to the rear collection equipment.
