The other side of the butt-joint conveying belt 52 opposite to the bag pushing opening 56 is provided with a push plate 58, and the push plate 58 is connected through a bag pushing cylinder 59.

On the butt joint conveyer belt 52, be located and detect that separation system is whole still to be equipped with whole package mechanism between the 3 output terminal of conveyer, this whole package mechanism includes two whole package guide boards 60, two whole package guide boards 60 erect in the both sides of butt joint conveyer belt 52 and form whole package passageway between the two, whole package passageway narrows down towards aircraft nose 2 direction gradually, whole package cylinder 61 has still been erect on the upper portion of two whole package guide boards 60, whole package cylinder 61 level sets up and both ends respectively with two whole package guide boards 60 rotate to be connected.

When the bag-type material conveying device works, a worker firstly puts the bag-type materials 1 into a front-end conveying belt (not shown) in sequence for conveying, and one end of the butt-joint conveying belt 52 needs to move along with the machine head 2, so that the front-end conveying belt needs to be in flexible connection with the conveying roller group 54, namely butt-joint conveying can be carried out, and certain relative movement can be allowed between the front-end conveying belt and the conveying roller group. The bagged objects 1 sequentially enter the conveying roller sets 54 through transmission, the sensing device detects the conveying condition, the control system combines the passing interval of the last bagged object 1 to adjust the conveying speed of each section of conveying roller set 54, for example, when the distance between the front and the rear bagged objects 1 is too close, the front section of conveying roller set 54 reduces the conveying speed to pull apart the distance between the front and the rear bagged objects 1 to make the distance meet the specified distance; if the distance between the front and rear two bagged materials 1 is too far, the front end conveying roller set 54 increases the conveying speed to retract the distance between the front and rear two bagged materials 1.

If there is a bag break during the transportation, the dropped contents may drop into the receiving funnel 55 from the gap to be collected (a dust suction device may be provided to prevent secondary contamination), and the weight of the bagged material 1 may be reduced. In the passing detection separation system, if the weight of the bagged object 1 is less than the set weight, the bag breaking condition of the bagged object 1 is proved, the bag pushing cylinder 59 works, the pushing plate 58 is driven to work to push the broken bag out of the bag pushing opening 56, and the broken bag enters the joint through the bag pushing channel 57 to be recovered. When the bagged object 1 passes through the whole-packaging mechanism, the left whole-packaging guide plate 60 and the right whole-packaging guide plate 60 are used for aligning and adjusting the two sides of the bagged object 1, the whole-packaging roller 61 is used for finishing the surface of the bagged object 1, and the bagged object 1 after being completely packaged is conveyed to a to-be-packaged station at the tail end of an output end by the butt-joint conveying belt 52.

The bag inlet 31 of the bag transfer box 22 at the bag transfer station faces the bag direction, the bagged materials 1 are directly sent into the bag transfer box 22, the bag transfer motor 29 controls the bag transfer box 22 to rotate 90 degrees, the bag inlet 31 faces the lifting channel direction at one side, the bagged materials 1 are adjusted from a vertical bag state to a horizontal bag state, and at the moment, the lifting bracket 32 and the turning plate 33 in the lifting channel are already at the highest bag loading station. Next, the translation motor 25 operates to drive the bag transfer box 22 to horizontally move to the bag loading station, and after the bag transfer box reaches the bag loading station, the bag-packed material 1 automatically falls onto the turning plate 33 at the bag loading station from the bag outlet 30. Then, the second lifting motor works to drive the lifting toothed belt 37 to operate, so as to drive the lifting bracket 32 and the turning plate 33 loaded with the bagged materials 1 to descend to a lower packaging station, and finally, the first packaging throwing motor 35 drives the two first packaging throwing shafts 34 to synchronously rotate so as to control the two turning plates 33 to be opened downwards, so that the bagged materials 1 fall into the corresponding packaging throwing box 41 below by means of self weight. Because two sets of transfer device 20 are fixed on same lift cingulum 37 and set up in both sides respectively, therefore when one of them group transfer device 20 descends to the lower package station that corresponds, another group transfer device 20 then just rises to the upper package station department that corresponds, and two sets of transfer device 20 realize ascending and descending in turn and connect the package, and change package device 21 and also cooperate two sets of transfer device 20 to realize controlling harmoniously packing simultaneously.

After the bag throwing box 41 receives the bagged object 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 relation, so that the box bottom 43 is controlled to be turned downwards and opened, and the bagged object 1 finally falls down and is thrown into a loading vehicle.

The present invention is equipped with multiple sets of horizontal and vertical adjustment mechanisms to achieve accurate delivery and palletizing of the bagged materials 1. For example: first horizontal control mechanism control aircraft nose 2 is whole at first horizontal direction adjustment motion, second horizontal control mechanism control movable frame 6 is for fixed frame 5 at second horizontal direction adjustment motion, first packet translation mechanism control of throwing is thrown a packet support 40 and is thrown the package again to the rear that movable frame 6 was removed to a packet box 41, let fixed frame 5 and movable frame 6 avoid driving the car curb plate, car back door and locomotive etc. throw in bagged object 1 to the distance that is nearer apart from the car back door, in order to guarantee to pile up bagged object 1 fully. The second package throwing translation mechanism can control the package throwing quantity and the space of the same row in the second horizontal direction. Through the translation adjustment of first horizontal direction and second horizontal direction, throw the package in proper order and pile up the completion with first layer, later with aircraft nose 2 lifting to the package height of throwing of last layer, repeat above-mentioned package process of throwing, accomplish the package of throwing of bagged materials 1 and pile up, all low-order at every turn throws the package, also can pile up earlier and accomplish first row, pile up one row.
