[0001] The invention relates to the technical field of packaging machinery, and in particular to a sorting machine with high-speed sorting and bag turning functions. Background Art

[0002] At present, most soft-bag beverages on the market have a straw attached to the outside of the soft bag. When the suction cup grabs the material with the straw on one side, it is easy to fall off during the moving and packing process. Therefore, the soft bag material needs to be flipped 180° so that the side without the straw faces up, which is convenient for subsequent suction cup grabbing and packing. Most sorting machines on the market use Delta3 robots for sorting, and the sorting method is single grabbing. For some packaging industries, the sorting speed cannot match and adapt to the speed of upstream and downstream production equipment, which limits the production efficiency of existing production lines.

[0069] The working principle of the present invention is as follows: the soft bag materials are first transported in an orderly manner through the feeding conveying component 300, and straws are pasted on the upper end surfaces of the soft bag materials on the feeding conveying component. Then, they are grabbed in groups by the robot component 200, and each group of suction cups includes two suction cups distributed diagonally. The two suction cups are respectively used to suck the end surfaces of the soft bag materials on both sides of the straws, and the soft bag materials are placed on the three-channel arrangement conveying component in sequence. After being accelerated by the acceleration conveying component 500, they are pulled apart, enter the bag turning component, flip 180°, and then fall into the feeding conveying component 700. The bag turning component flips the straw surface of the soft bag material from the upper end surface to the lower end surface, so that when sucking multiple soft bag materials in the subsequent grabbing and packing process, it is necessary to change the distance between adjacent soft bag materials. Therefore, the contact area between the suction cup and the soft bag material is larger, ensuring a large suction force to avoid the soft bag material being thrown off during the movement process, and then conveyed to the packing machine for group packing. The Delta3 robot 201 is used in combination with the technology of first regularizing and then grouping grabbing and conveying, which significantly improves the speed of material sorting and bag turning, and improves the production efficiency of the entire production line. The whole process is fully automated, with a simple structure and fast sorting speed. It can sort and turn over 450 materials per minute, making it an ideal high-speed sorting and bag turning equipment, especially suitable for high-speed sorting and bag turning production lines.

[0070] The arrangement order of the components is the feeding conveying component 300, the arranging conveying component 400, the accelerating conveying component 500, the bag turning mechanism 600 and the bag feeding conveying component 700; when the robot component 200 grabs and places materials, the feeding conveying component 300 and the arranging conveying component 400 are in a following state, realizing non-stop grabbing and placing.

[0071] The arranging conveying component 400 and the accelerating conveying component 500 are arranged on a horizontal plane, and the accelerating conveying component 500 is arranged behind the arranging conveying component 400. The three accelerating belt conveyors and the three arranging belt conveyors are connected end to end respectively.

[0072] The feed conveying component 300 is arranged between the first arrangement belt conveyor and the second arrangement belt conveyor of the three-channel arrangement conveying component 400, and the conveying surface is lower than the conveying surface of the arrangement conveying component 400; the arrangement belt conveyor, acceleration belt conveyor, and package feeding belt conveyor each include three parts: a frame, a foot frame and a belt, and the belt is a smooth belt.

[0073] The bag turning mechanism 600 is arranged behind the accelerating conveying component 500. The soft bag material passing through the accelerating conveying component 500 enters the bag turning mechanism 600, is turned 180 degrees and is output.

[0074] The bag-infeeding conveying component 700 is arranged behind the bag-turning mechanism, and the turned soft bag materials fall steadily onto the bag-infeeding conveying component 700 and are output to the subsequent case packing machine for case packing.

[0075] The robot component 200 is arranged above the arrangement and conveying component 400, and the gripper thereon grabs the materials and places them on the first arrangement belt conveyor, the second arrangement belt conveyor, and the third arrangement belt conveyor in sequence.

[0076] The conveying speed of the bag feeding belt conveyor is greater than that of the accelerating belt conveyor, and the speed of the accelerating belt conveyor is greater than that of the arranging belt conveyor, so as to realize the sub-packaging of soft bag materials and keep a certain distance between adjacent materials to prepare for material packing.

[0077] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
