When in operation, workers firstly put the bagged objects 1 on a front-end conveying belt (not shown in the figure) in sequence for conveying, and as one end of the butt-joint conveying belt 52 needs to move along with the machine head 2, the front-end conveying belt and the conveying roller set 54 need to be in flexible connection, namely butt-joint conveying can be performed, but certain relative movement can be allowed between the front-end conveying belt and the conveying roller set. The bagged materials 1 enter the conveying roller set 54 in sequence through transmission, the conveying condition is detected by the sensing device, the control system combines the passing interval of the bagged materials 1, the conveying speed of each section of conveying roller set 54 is adjusted, when the distance between the front bagged material 1 and the rear bagged material 1 is too close, the conveying speed of the front section of conveying roller set 54 is reduced, so that the distance between the front bagged material 1 and the rear bagged material 1 is pulled to be consistent with the specified distance, and when the distance between the front bagged material 1 and the rear bagged material 1 is too far, the conveying speed of the front conveying roller set 54 is increased, so that the distance between the front bagged material 1 and the rear bagged material 1 is retracted.

If there is a broken bag during the transportation, the dropped contents can be dropped from the gap into the hopper 55 for collection (dust collection equipment can be provided to prevent secondary pollution), and the weight of the bagged materials 1 is reduced. In the detection and separation system, if the weight of the bagged material 1 is less than the set weight, the bagged material 1 is proved to have a bag breaking condition, the bag pushing cylinder 59 is operated, the push plate 58 is driven to push the bag breaking out of the bag pushing port 56, and the bag breaking enters the joint through the bag pushing channel 57 for recovery. When the bagged material 1 passes through the bagging mechanism, the left and right bagging guide plates 60 are used for adjusting the two sides of the bagged material 1, the surface of the bagged material 1 is trimmed by the bagging roller 61, and the bagged material 1 after finishing the bagging is conveyed to a station to be converted at the output end by the butt-joint conveying belt 52.

The bag feeding port 31 of the bag box 22 at the station to be transferred faces the bag feeding direction, the bag 1 is directly fed into the bag box 22, the bag transferring motor 29 controls the bag box 22 to rotate 90 degrees, the bag feeding port 31 faces the lifting channel direction on one side, the bag 1 is adjusted from the vertical bag state to the horizontal bag state, and the lifting bracket 32 and the turning plate 33 in the lifting channel are at the highest position at the loading station. Next, the translation motor 25 operates to drive the subcontracting box 22 to move horizontally to the subcontracting station, and after reaching the subcontracting station, the bagged material 1 automatically falls from the outlet 30 onto the flap 33 at the subcontracting station. Then, the second lifting motor works to drive the lifting toothed belt 37 to run, drive the lifting bracket 32 and the turning plates 33 carrying the bagged objects 1 to descend to the lower bag station, and finally the first bag throwing motor 35 drives the two first bag throwing shafts 34 to synchronously rotate so as to control the two turning plates 33 to open downwards, and the bagged objects 1 fall into the corresponding bag throwing boxes 41 below by means of dead weight. Because the two groups of transfer devices 20 are fixed on the same lifting toothed belt 37 and are separately arranged on two sides, when one group of transfer devices 20 descends to the corresponding lower packaging station, the other group of transfer devices 20 just ascends to the corresponding upper packaging station, the two groups of transfer devices 20 realize alternate lifting and package receiving, and the transfer device 21 also cooperates with the two groups of transfer devices 20 to realize left-right coordination package receiving.

After the bag throwing box 41 receives the bagged materials 1, the second bag throwing motor 45 drives the bag throwing driving shaft 46 to rotate, and drives the second bag throwing shaft 44 to rotate through the meshing relationship, so that the bottom 43 of the control box is turned down and opened, and the bagged materials 1 finally fall down and are thrown into the loading vehicle.

The invention is provided with a plurality of groups of horizontal and vertical adjusting mechanisms to realize the accurate throwing and stacking of the bagged materials 1. For example, the first horizontal control mechanism controls the whole machine head 2 to move in a first horizontal direction, the second horizontal control mechanism controls the movable frame 6 to move in a second horizontal direction relative to the fixed frame 5, the first bag throwing translation mechanism controls the bag throwing support 40 and the bag throwing box 41 to move to the rear of the movable frame 6 and then throw bags, the fixed frame 5 and the movable frame 6 avoid side plates, a rear door, a vehicle head and the like, and the bagged materials 1 are thrown to a distance close to the rear door of the vehicle, so that the bagged materials 1 are ensured to be fully stacked. The second ladle transferring mechanism can control the ladle quantity and the ladle interval of the same row in the second horizontal direction. Through the translation adjustment of the first horizontal direction and the second horizontal direction, the first layer of the package is stacked, then the machine head 2 is lifted to the package-throwing height of the previous layer, the package-throwing process is repeated, the package-throwing stacking of the bagged objects 1 is completed, the package is thrown at a low position each time, the first row can be stacked firstly, and the first row can be stacked row by row.
