When working, the staff first put the bagged items 1 on the front-end conveyor belt (not shown in the figure) for conveyance. Since one end of the butt conveyor belt 52 needs to follow the movement of the machine head 2, the front-end conveyor belt and the conveyor roller group are required. 54 is a soft connection, that is, it can perform docking transmission, but a certain relative activity is allowed between the two. The bagged objects 1 enter the conveying roller group 54 in turn through transmission, and the conveying situation is detected by the sensing device, and the control system adjusts the conveying speed of each section of the conveying roller group 54 in combination with the passing interval of the previous bagged object 1, for example, the front and rear two When the distance between the bagged objects 1 is too close, the conveying roller group 54 in the front section will reduce the conveying speed to open the distance between the two front and rear bagged objects 1 so as to meet the specified distance; if the distance between the two front and rear bagged objects 1 is too far , and the front-end conveying roller group 54 accelerates the conveying speed to shrink the distance between the front and rear bagged objects 1 .

During the conveying process, if there is a broken bag, the dropped contents can be dropped from the gap into the bucket 55 for collection (a vacuuming device can be equipped to prevent secondary pollution), and the weight of the bag 1 is reduced. In the separation system by detection, if the weight of the bag 1 is less than the set weight, it proves that the bag 1 is broken. The port 56 is pushed out, and the broken bag enters the joint through the push bag channel 57 for recovery. When the bag 1 passes through the whole bag mechanism, the left and right two whole bag guide plates 60 adjust the two sides of the bag 1, the whole bag roller 61 trims the surface of the bag 1, and the bag after the whole bag is completed. The load 1 is transported by the docking conveyor belt 52 to the station to be subcontracted at the output end.

The package inlet 31 of the subpackage box 22 at the subcontracting station is oriented towards the direction of incoming packages, the packaged goods 1 are directly sent into the subpackage box 22, and the subpackage motor 29 controls the subpackage box 22 to rotate 90°, so that the package inlet 31 faces the direction of the lifting channel on one side, the bag 1 is adjusted from the vertical packaging state to the horizontal packaging state, and the lifting bracket 32 and the flap 33 in the lifting channel are already at the upper packaging station at the highest position. Next, the translation motor 25 works to drive the sub-packaging box 22 to move horizontally to the upper-packing station. After reaching the upper-packing station, the bagged object 1 automatically falls from the outlet 30 to the flap 33 at the upper-packing station. After that, the second lifting motor works, driving the lifting toothed belt 37 to run, driving the lifting bracket 32 and the flap 33 carrying the bag 1 to descend to the lowering station, and finally the first bag feeding motor 35 drives the two first The bag feeding shaft 34 rotates synchronously to control the two flaps 33 to open downward, and the bag 1 falls into the corresponding bag feeding box 41 below by its own weight. Since the two sets of transfer devices 20 are fixed on the same lifting toothed belt 37 and are located on both sides, when one set of transfer devices 20 descends to the corresponding sub-contracting station, the other set of transfer devices 20 just rises to the corresponding upper-contracting station The two groups of transfer devices 20 realize alternate lifting and lowering of receiving packages, and the subcontracting device 21 also cooperates with the two groups of transfer devices 20 to realize left and right coordinated subcontracting.

After the package delivery box 41 receives the bag 1, the second package delivery motor 45 drives the package delivery drive shaft 46 to rotate, and through the meshing relationship, drives the second package delivery shaft 44 to rotate, thereby controlling the bottom 43 of the box to turn down and open. , the bag 1 is finally dropped and thrown into the loading vehicle.

The utility model is equipped with a plurality of sets of horizontal and vertical adjustment mechanisms to achieve precise placement and stacking of the bagged objects 1 . For example: the first horizontal control mechanism controls the overall movement of the nose 2 in the first horizontal direction, the second horizontal control mechanism controls the movable frame 6 to adjust the movement in the second horizontal direction relative to the fixed frame 5, and the first package delivery translation mechanism controls the delivery The bag holder 40 and the bag throwing box 41 are moved to the rear of the movable frame 6 and then the bag is cast, so that the fixed frame 5 and the movable frame 6 avoid the side panel, the rear door and the front of the vehicle, etc. close distance to ensure full stacking of bag 1. The second package delivery translation mechanism can control the number and spacing of packages delivered in the same row in the second horizontal direction. Through the translational adjustment of the first horizontal direction and the second horizontal direction, the first layer is stacked in turn by bagging, and then the machine head 2 is lifted to the bagging height of the previous layer, and the above-mentioned bagging process is repeated to complete the bag 1. The packages are stacked, and each time is a low-level package, or you can stack the first column first, and stack them one by one.
