[0062] like Fig. 9 As shown, the conveying device 3 includes a conveying support 51, a docking conveyor belt 52 and a plurality of adjustable rollers 53, wherein the plurality of adjustable rollers 53 are arranged in sequence to form a conveying roller group 54, wherein the docking conveyor belt 52 is arranged on the conveying support 51 and one end thereof is extended into the movable frame 6 as an output end, and the other end thereof is docked with the conveying roller group 54, wherein the docking conveyor belt 52 and the conveying roller group 54 each have their own power systems, and a sensing device is arranged on the conveying roller group 54, wherein the sensing device is used to detect the passing bagged objects 1, and an infrared sensor commonly used in the prior art can be adopted. The conveying roller group 54 is divided into at least two sections, and the power system corresponding to each section is relatively independent, and each section is provided with a first sensing device. The first sensing device detects the passing bagged objects 1, and the control system can control the conveying speed of each section of the conveying roller group 54 according to the passing interval between the two bagged objects 1 in front and behind, so as to keep the bagged objects 1 entering the docking conveyor belt 52 at a consistent interval.

[0063] The lower part of the conveying bracket 51 is provided with a receiving bucket 55, which is larger at the top and smaller at the bottom, and the conveying roller set 54 is located directly above the joint. There is a gap between the spacing rollers 53, and when the broken bag 1 passes through the conveying roller set 54, the fallen contents can fall from the gap into the receiving bucket 55 for collection, and will not accumulate on the conveying roller set 54.

[0064] A detection and separation system is also provided at the joint of the butt conveyor belt 52 and the conveyor roller group 54. The detection and separation system includes a weight sensor. A bag pushing opening 56 is provided at one side of the butt conveyor belt 52 at the weight sensor. The bag pushing opening 56 is connected to the receiving bucket 55 through a bag pushing passage 57. A push plate 58 is provided at the other side of the butt conveyor belt 52 relative to the bag pushing opening 56. The push plate 58 is connected through a bag pushing cylinder 59.

[0065] On the docking conveyor belt 52, a whole-pack mechanism is also provided between the detection and separation system and the output end of the conveying device 3. The whole-pack mechanism includes two whole-pack guide plates 60. The two whole-pack guide plates 60 are erected on both sides of the docking conveyor belt 52 and form a whole-pack channel therebetween. The whole-pack channel gradually narrows toward the direction of the machine head 2. A whole-pack roller 61 is also mounted on the upper part of the two whole-pack guide plates 60. The whole-pack roller 61 is horizontally arranged and the two ends are rotatably connected to the two whole-pack guide plates 60 respectively.

[0066] During operation, the staff first puts the bags 1 onto the front conveyor belt (not shown) for transportation. Since one end of the docking conveyor belt 52 needs to move with the machine head 2, the front conveyor belt needs to be softly connected to the conveyor roller group 54, that is, docking transmission can be performed, but a certain relative movement is allowed between the two. The bags 1 are transported into the conveyor roller group 54 in turn, and the conveying status is detected by the sensing device. The control system adjusts the conveying speed of each section of the conveyor roller group 54 in combination with the passing interval of the previous bag 1. For example, when the distance between the front and rear bags 1 is too close, the front section of the conveyor roller group 54 reduces the conveying speed to open the distance between the front and rear bags 1 to meet the specified distance; if the distance between the front and rear bags 1 is too far, the front section of the conveyor roller group 54 speeds up the conveying speed to shrink the distance between the front and rear bags 1.

[0067] During the conveying process, if there is a broken bag, the fallen contents can fall from the gap into the receiving bucket 55 for collection (it can be equipped with dust collection equipment to prevent secondary pollution), and the weight of the bag 1 is reduced. In the detection and separation system, if the weight of the bag 1 is less than the set weight, it proves that the bag 1 is broken, and the bag pushing cylinder 59 works to drive the push plate 58 to push the broken bag out of the bag pushing port 56, and the broken bag enters the joint through the bag pushing channel 57 for recovery. When the bag 1 passes through the bagging mechanism, the left and right bagging guide plates 60 align and adjust the two sides of the bag 1, and the bagging roller 61 trims the surface of the bag 1. After the bagging is completed, the bag 1 is transported to the transfer station at the output end by the docking conveyor belt 52.

[0068] The bag inlet 31 of the sub-packaging box 22 at the sub-packaging station faces the incoming bag direction, and the bagged object 1 is directly fed into the sub-packaging box 22. The sub-packaging motor 29 controls the sub-packaging box 22 to rotate 90 degrees, so that the bag inlet 31 faces the lifting channel on one side, and the bagged object 1 is adjusted from the vertical bagging state to the horizontal bagging state, and at this time, the lifting bracket 32 ​​and the flap 33 in the lifting channel are already at the highest position of the upper bagging station. Next, the translation motor 25 drives the sub-packaging box 22 to move horizontally to the upper bagging station. After arriving at the upper bagging station, the bagged object 1 automatically falls from the bag outlet 30 onto the flap 33 at the upper bagging station. After that, the second lifting motor starts to work, driving the lifting toothed belt 37 to operate, driving the lifting bracket 32 ​​and the flap 33 carrying the bagged objects 1 to descend to the lower bagging station, and finally the first bagging motor 35 drives the two first bagging shafts 34 to rotate synchronously to control the two flaps 33 to open downward, and the bagged objects 1 fall into the corresponding bagging box 41 below by their own weight. Since the two groups of transfer devices 20 are fixed on the same lifting toothed belt 37 and are arranged on both sides, when one group of transfer devices 20 descends to the corresponding lower bagging station, the other group of transfer devices 20 just rises to the corresponding upper bagging station, and the two groups of transfer devices 20 realize alternating lifting and receiving packages, and the subcontracting device 21 also cooperates with the two groups of transfer devices 20 to realize left and right coordinated subcontracting.

[0069] After the bag box 41 receives the bag 1, the second bag motor 45 drives the bag driving shaft 46 to rotate, and through the meshing relationship, drives the second bag shaft 44 to rotate, thereby controlling the box bottom 43 to flip downward and open, and the bag 1 finally falls and is thrown into the loading vehicle.

[0070] The present invention is equipped with multiple groups of horizontal and vertical adjustment mechanisms to achieve accurate delivery and stacking of bagged objects 1. For example: the first horizontal control mechanism controls the head 2 as a whole to adjust and move in the first horizontal direction, the second horizontal control mechanism controls the movable frame 6 to adjust and move relative to the fixed frame 5 in the second horizontal direction, and the first bag delivery translation mechanism controls the bag delivery bracket 40 and the bag delivery box 41 to move to the rear of the movable frame 6 before delivering bags, so that the fixed frame 5 and the movable frame 6 avoid the side panels, the rear door and the front of the vehicle, etc., and deliver the bagged objects 1 to a distance close to the rear door of the vehicle to ensure that the bagged objects 1 are fully stacked. The second bag delivery translation mechanism can control the number and spacing of bags delivered in the same row in the second horizontal direction. Through the translation adjustment in the first horizontal direction and the second horizontal direction, the first layer of bags are delivered in sequence to complete the stacking, and then the head 2 is lifted to the bag delivery height of the upper layer, and the above-mentioned bag delivery process is repeated to complete the bag delivery and stacking of the bagged objects 1. Each time, the bags are delivered at a low position, and the first column can also be stacked first, and then the bags are stacked one by one.
