DETAILED DESCRIPTION

[0026] The content of the utility model will be further explained in detail in combination with specific embodiments:

[0027] As Figures 1-3 shown, the utility model is applied to the unstacking and transfer of the stacked turnover boxes. In the production turnover process, generally, multiple turnover boxes are stacked and placed and transferred through a tray, when transferred to the unstacking mechanism, the turnover boxes are taken out one by one through the unstacking mechanism and transferred to the designated position. Specifically:

[0028] An unstacking mechanism, comprising a rack and a base 1 movably connected with the rack through a guide device in Y-axis direction, a fifth driving device 11 is connected on the base 1, and the fifth driving device 11 drives the rack 2 to move along the Y-axis direction on the base 1.

[0029] The rack 2 is provided with a lifting assembly 3, the lifting assembly 3 comprises a second support 31 and a third driving device 32 connected with the second support 31, and the third driving device 32 is connected with the rack 2 simultaneously. The third driving device 32 can drive the second support 31 to move along the Z-axis direction.

[0030] The second support 31 is provided with a fourth driving device 33, the fourth driving device 33 is connected with a first support 41 of a carrying cabin 4, and the fourth driving device 33 drives the carrying cabin 4 to move along the X-axis direction on the second support 31 through the first support 41.

[0031] The carrying cabin 4 comprises the first support 41, the first support 41 is square as a whole, the upper end is connected with the second support 31, and the lower end is provided with a drum conveying belt 42 in the conveying direction Y. The first support 41 upper end is connected with a hook claw device through a first driving device 43 in the driving direction Y.

[0032] The hook claw device 44 comprises a hook 441 and a second driving device 442 connected with the hook 441, the second driving device 442 is connected with the first driving device 43, and the second driving device 442 can drive the hook 441 to move in the Z-axis direction, so as to hook the box body from bottom to top.

[0033] The hook 441 is connected with the second driving device 442 through a fixing block 443. The fixing block 443 is connected with a vertical first guide rod 444. The lower end of the first guide rod 444 is connected with a pressing plate 445. The pressing plate 445 extends to the hook 441 and is located between the hook tip and the hook bend of the hook 441 in the Z-axis direction. The upper end of the first guide rod 444 is connected with an inductive sheet 446. The inductive sheet 446 is connected with a first sensor 447 connected with the hook 441. The fixing block 443 is connected with a second sensor 45. The sensing direction of the second sensor 45 is the Y-axis direction and faces and penetrates a gap 4411 on the hook 441. The second sensor 45 is arranged above the hook 441.

[0034] In the embodiment, when the unstacking operation is performed, the rack 2 moves towards the toter direction in the Y-axis direction under the driving of the fifth driving device 11, thereby driving the carrying cabin 4 to move towards the toter direction. When the second sensor 45 senses the toter, the driving is stopped. Then, the carrying cabin 4 moves upwards in the Z-axis direction under the driving of the third driving device 32 through the second support 31. When the second sensor 45 cannot sense the toter, the driving is stopped. Then, the carrying cabin 4 continues to move towards the toter direction in the Y-axis direction under the driving of the fifth driving device 11 for a predetermined distance, and then stops. At this time, the hook 441 is located directly below the handle of the toter. Then, the hook 441 moves upwards in the Z-axis direction under the driving of the second driving device 442. During the movement, when the handle of the toter presses the pressing plate 445, the inductive sheet 446 moves downwards relative to the fixing block 443 through the first guide rod 444, so that the first sensor and the inductive sheet 446 are in induction. At this time, it is indicated that the hook 441 has been accurately connected with the handle. The second driving device 442 continues to drive the hook 441 to move upwards for a predetermined distance, continues to pull the toter, so that the end of the toter close to the carrying cabin is lifted and is higher than the roller conveying belt 42. Then, the toter is pulled to the upper end of the roller conveying belt under the driving of the first driving device 43. The hook 441 moves downwards and away from the toter under the driving of the second driving device 442 and the first driving device 43, so as to be separated from the toter. Finally, the carrying cabin 4 drives the toter to a predetermined position under the driving of the third driving device 32, the fourth driving device 33 and the fifth driving device 11, and the toter is transported out.
