Referring to fig. 18, preferably, the blocking portion 2 includes a plurality of rollers 21 arranged in parallel, and a belt 22 is wrapped outside the rollers 21; after the turnover frame 300 is turned over, the stacked goods package 200 is leaned on the belt 22, and when the goods package 200 is pushed up, the belt 22 rotates along with the goods package, so that the pushing-up resistance is reduced.

During the operation, upset frame 300 slopes to predetermined angle, the utility model discloses preferred slope is to 40-85, and drum assembly 100 stirs the goods package 200 of the superiors, follows the export roll-off in proper order, falls rapidly on the equipment of next process under the effect of gravity, like conveyer belt or bag breaker etc..

Referring to fig. 2, the drum assembly 100 has a plurality of drums 1 arranged in an array; each roller 1 is rotatably erected on the hanger 13 and can independently rotate to stir the goods package 200 to slide along the conveying direction; referring to fig. 3, each roller 1 is connected to a pre-pressing member 12; the pre-pressure 12 provides a pre-pressure that keeps the cylinder 1 pressed against the bale 200, preventing it from tipping over.

Preferably, the hangers 13 are connected to the guide rods 11, and the number of the guide rods 11 is preferably 4.

Further, the pre-pressing pieces 12 are air cylinders, all the air cylinders are connected with the same air pressure source, the same pre-pressing force is provided, the pre-pressing force cannot change along with the extension length of the telescopic rods of the air cylinders, and the stable pre-pressing force is always kept.

In one embodiment, the pre-pressing member 12 is a spring, and the spring is sleeved on the guide rod 11.

Referring to fig. 4, the drum 1 is a hollow structure, and a drum motor 14 for driving the drum to rotate is arranged in the drum; referring to fig. 5, one end of the drum motor 14 is fixedly connected with a hanger 13 and is rotatably connected with the drum 1 through a bearing 15; referring to fig. 6, the motor spindle 141 at the other end of the drum motor 14 is fixedly connected to the drum 1 and is rotatably connected to the hanger 13 through the bearing 15.

The drum motor 14 is arranged inside the drum 1 to drive the drum to rotate, and the structure is compact, and the drum 1 is arranged in an array.

Preferably, the surface of the roller 1 is provided with a plurality of bulges, so that the bag poking power is improved; further, the protrusions are provided with friction layers to facilitate the picking of the luggage 200; the friction layer is preferably made of rubber or resin.

As an example:

referring to fig. 7, the roller assembly 100 has a first driving region 10, a swing driving region 20 and a second driving region 30; the first driving region 10 and the drum 1 of the second driving region 30 are alternately rotated, and the drum 1 of the swing driving region 20 is rotated in synchronization with the first driving region 10 or the second driving region 30 according to a predetermined program.

Referring to fig. 8, a upper layer stack shape: the rollers 1 of the first drive zone 10 of the roller assembly 100 individually pick the packages 200 placed in the forward direction (parallel to the conveying direction); the rocking drive zone 20 operates in synchronism with the rollers 1 of the second drive zone 30 to move the transversely (perpendicular to the conveying direction) positioned bale 200.

The control unit controls each roller motor 14 to make the rollers 1 of each driving area act according to a set program, and each time a parcel 200 falls out from the outlet until all the parcels 200 on the layer are pulled out.

b, lower-layer stacking: due to the stubble biting placement, the orientation of the next layer of bales 200 is different from the orientation of the previous layer; at this time, the swing driving area 20 and the roller 1 of the first driving area 10 act synchronously to shift the transversely placed luggage 200; the rollers 1 of the second drive zone 30 individually pick the packages 200 placed in the forward direction.

Referring to fig. 9, after the front parcel 200 is pulled out, the next adjacent parcels 200 are sequentially supplemented in place; the last bag leaves a vacant position after going forward, and the corresponding roller 1 at the position extends forwards under the pushing of the prepressing part 12 and presses on the next layer of the goods bag 200 to prevent the goods bag from rolling automatically; at the same time, the drum 1, which is extended forward and pressed down, stops rotating. When the upper layer of the bales 200 completely falls down, the lifting frame body 3 moves up by the distance of one layer of the bales 200, the roller 1 pressed on the bales 200 contracts along with the movement, and the disassembly of the layer of the bales 200 is started. And each layer is disassembled according to the process until the whole stack is unpacked.

Because the overturning frame 300 is inclined at a larger angle in the working state, the component force of the gravity of each goods package 200 in the transmission direction is larger, and the roller 1 can stir the goods package 200 to move forwards only by smaller stirring power. The goods package 200 can fall down rapidly under the action of gravity after reaching the outlet, so that the driving time of two adjacent packages is short, and the continuous pulling-out of the goods package 200 can be realized by setting a proper time length in the control unit to control the start and stop of each roller motor 14.

Because the utility model has a goods bag 200 standing by at the exit position all the time in the unstacking process, the bag dropping action is continuous and compact; and the posture of the package stack and the roller assembly 100 does not need to be adjusted when the stack is unstacked; therefore, the time for unstacking is greatly reduced, and the unstacking efficiency is improved.

According to the stack arrangement, the roller assembly 100 of the present invention has at least 3 rows of rollers 1, i.e., at least one roller 1 is pressed and driven for each bale 200; the utility model discloses preferably 6 rows, make pressing and the drive process of goods package 200 more stable (each cisoid goods package 200 has 3 cylinders 1 to push down, and each horizontal goods package 200 has 2 cylinders 1 to push down), avoid goods package 200 goods package to empty.

The first driving area 10 and the second driving area 30 of the present embodiment are both two rows of rollers 1, and the swing driving area 20 is one row of rollers 1;

with reference to fig. 10, the first driving area 10 and the second driving area 30 of the present embodiment may also be an array of rollers 1; further, the length of the roller 1 located in the first driving region 10 and the second driving region 30 is twice the length of the roller 1 of the swing driving region 20 for stabilizing the pack.
