[0060] As Figures 1-5In one embodiment, the second branch conveying line comprises a drum conveying line and a main belt extension conveying line 41. The drum conveying line comprises a support platform 36 located at a downstream position of the main belt line 1 and a plurality of drums 37 arranged in parallel and at the same height as the main belt line 1. The axial direction of each drum 37 is perpendicular to the conveying direction of the main belt line 1. The upper surface of the support platform 36 is provided with a support plate 38 corresponding to the axial ends of each drum 37. The two ends of each drum 37 in the axial direction are rotatably connected to the corresponding support plate 38. The end of the plurality of drums 37 on the same side in the axial direction is formed with a transmission section. The drum close to the main belt line 1 is a first drum 39. The transmission section of the first drum 39 is provided with an input sprocket and an output sprocket. The output end of a fifth motor 40 is fixed with a sprocket. The sprocket and the input sprocket are connected through a chain.

The transmission section between each two adjacent drums 37 is connected through a chain transmission. The drum away from the main belt line 1 is provided with the main belt extension conveying line 41. The drum 37 and the main belt extension conveying line 41 are at the same height.

[0061] The first branch conveying line comprises a plurality of sorting belt lines 42 for sorting the first yarn roll 2. The sorting belt line 42 is arranged between two adjacent drums 37. The lifting platform 44 is located above the support platform 36 and below the plurality of drums 37. The lifting platform 44 is provided with a plurality of sorting belt lines 42. The lifting platform 44 is provided with a main transmission rod 45 corresponding to the same end of the plurality of sorting belt lines 42.

[0062] The controller is electrically connected to the fifth motor 40, the sixth motor 46, the lifting cylinder 43 and a seventh motor for controlling the start and stop of the main belt extension conveying line 41.

[0063] When the second branch conveyor line conveys several second yarn rolls 3, the lifting cylinder 43 is in a retracted state, causing several sorting belt lines 42 to be lower than the roller 37. When the first branch conveyor line conveys several first yarn rolls 2, the roller conveyor line and the main belt extension conveyor line 41 stop operating and the lifting cylinder 43 is in an extended state, causing several sorting belt lines 42 to be at the same height as the main belt line 1 and the transmission belt line 5.

[0064] The number of first yarn rolls 2 in each yarn roll stack 66 is 4.

[0065] like Figures 1-5 As shown, in one specific embodiment, the automatic splice palletizing system 4 further includes a splice support platform 47. The conveyor belt 5 and the yarn roll stacking conveyor belt 6 are both arranged on the splice support platform 47, and their conveying directions are perpendicular. The starting end of the yarn roll stacking conveyor belt 6 is close to the end of the conveyor belt 5. A first slide rail 48 is provided above the end of the conveyor belt 5. The extension direction of the first slide rail 48 is perpendicular to the conveying direction of the conveyor belt 5. A slider is slidably installed on the first slide rail 48. A robotic arm 49 capable of rotating 90° is installed at the end of the slider. The first slide rail 48 is supported by a second slide rail 50 arranged vertically and fixed on the splice support platform 47. The first slide rail 48 is slidably connected to the second slide rail 50. The system also includes a first cylinder that drives the first slide rail 48 to slide up and down along the second slide rail 50, and a second cylinder that drives the slide rail to reciprocate along the first slide rail 48. The controller is electrically connected to the robotic arm 49, the first cylinder, and the second cylinder.

[0066] Each of the yarn roll stacking and pressing mechanisms includes a third cylinder and a circular pressure plate 51 located at the end of the third cylinder. The size of the circular pressure plate 51 matches the size of the yarn roll. The extension and retraction direction of the third cylinder is vertical. It also includes a third slide rail 52. The extension direction of the third slide rail 52 is the same as the conveying direction of the yarn roll stacking conveyor belt 6. The third slide rail 52 is supported on the joint support platform 47 by a support rod. All three third cylinders are fixed on a moving rod that can reciprocate along the third slide rail 52. It also includes a fourth cylinder that drives the moving rod to reciprocate. The controller is electrically connected to the third cylinder and the fourth cylinder.

[0067] In this specific implementation, such as Figure 2As shown, the positions of the inner joint and the outer joint of the second yarn roll 3 conveyed by the conveying belt line 5 are already determined positions (the same, the positions of the inner joint and the outer joint of the adjacent second yarn roll 3 on the main belt line 1 are also determined positions, and the orientation of the second yarn roll 3 is rotated by 90 degrees through the sorting belt line 42). As shown, the inner joint is oriented towards the outer joint in a direction perpendicular to the conveying direction of the conveying belt line 5, and then a sensor arranged on one side of the conveying belt line 5 is used to sense whether the second yarn roll 3 passes, and if so, a signal is transmitted to the controller, and then the controller controls the movement of the mechanical arm 49 along the first slide rail 48, and the movement of the first slide rail 48 along the second slide rail 50, and then the mechanical arm 49 is rotated by 90 degrees to grasp the second yarn roll 3, and then reset to place the second yarn roll 3 on the yarn roll stack conveying belt line 6. When four second yarn rolls 3 are formed into a yarn roll stack 66, the controller controls the joint mechanism 7 to act. After the joint action is completed, the controller drives the yarn roll stack pressing mechanism to act, so that the circular pressing plate 51 presses the top of the yarn roll stack 66, and moves along the third slide rail 52 to follow the yarn roll stack moving along the conveying direction of the yarn roll stack conveying belt line 6. It can be understood that the side of the main belt line 1 is also provided with a sensor connected to the controller, which is used to sense whether the first yarn roll 2 passes, and if so, a signal is transmitted to the controller to control the sorting belt line 42 to act and the drum 37 and the main belt extension conveying line 41 to be inactive. Correspondingly, when the second yarn roll 3 is conveyed in batches, the sensor senses the second yarn roll 3, and then the controller controls the drum 37 and the main belt extension conveying line 41 to act and the sorting belt line 42 to be inactive.

[0068] In one embodiment, as shown in Figures 1-5 The transfer part includes a 6-axis robot 53 and a clamp placing rack 54, the clamp placing rack 54 is provided with a joint stacking clamp 55, a non-joint stacking clamp 56 and a paperboard suction clamp 57, the joint stacking clamp 55 is used to grasp the yarn roll stack 66 conveyed by the yarn roll stack conveying belt line 6, the non-joint stacking clamp 56 is used to grasp each second yarn roll 3 conveyed by the main belt extension line 41, and the paperboard suction clamp 57 is used to grasp the paperboard, and the joint stacking clamp 55, the non-joint stacking clamp 56 and the paperboard suction clamp 57 are detachably connected to the mechanical arm of the 6-axis robot 53.

[0069] Further comprising a paperboard placing station 65 for placing a plurality of mutually stacked paperboards.

[0083] The air twister 33 used in the present application is a commercially available product, and its specific structure will not be described in detail here.

[0084] The present application processes batches of first yarn rolls 2 or batches of second yarn rolls 3. For example, if the batch of yarn rolls are all first yarn rolls 2 that need to be jointed, the first yarn rolls 2 are sequentially transported through the main belt line 1 and then enter the automatic jointing and stacking system to complete the corresponding actions. If the batch of yarn rolls are all second yarn rolls 3 that do not need to be jointed, the transportation is completed through the main belt line 1, the roller 37 and the main belt extension conveying line 41.
