Referring to fig. 1, the present invention provides an array type bag-poking mechanism, which includes a turning frame 300 rotatable around a fixed fulcrum; the roller assembly 100 is installed on the upper part of the turnover frame 300; the overturning frame 300 is also provided with a lifting disc 3 for placing the tray 400;

the tray 400 holds the stacked packs 200; after the tray 400 is placed on the lifting tray 3, the roller assembly 100 is pressed against the uppermost one of the bales 200.

One side of the turnover frame 300 is opened to facilitate the entrance of the pallet 400, and the other end thereof has a blocking part 2 to block the stack of goods from falling down when it is tilted. Above the blocking portion 2 there is an outlet for the passage of the bale 200.

In operation, the turnover frame 300 is inclined to a predetermined angle, preferably 40-85 degrees according to the present invention, and the roller assembly 100 stirs the uppermost parcel 200, which slides out of the outlet in sequence, and rapidly falls onto the equipment of the next process, such as a conveyor belt or a bag breaker, under the action of gravity.

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, the rollers 1 of the first drive zone 10 of the roller assembly 100 individually pick the parcels 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.

Referring to fig. 8-b, the orientation of the next layer of bags 200 is different from the previous layer due to the stubble-biting placement; 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 is completely fallen down, the lifting plate 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.

In the unstacking process, one goods package 200 is always ready at the outlet position, so that the package 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 stacked arrangement, the roller assembly 100 of the present invention has at least 3 rows of rollers 1, i.e., at least one roller 1 per bale 200 is pressed and driven; the preferred embodiment of the present invention is 6 rows, which makes the pressing and driving process of the bale 200 more stable (3 rollers 1 for each

forward bale

200 and 2 rollers 1 for each lateral bale 200) and prevents the bale 200 from falling down.

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.

The present embodiment is suitable for disassembling quintuplet stacks or quintuplet stacks with similar arrangement, and those skilled in the art can adaptively increase or decrease the number of rows or columns of the rollers 1 in the roller assembly 100 according to the foregoing working principle according to the specification of the actual stack.

As an example, referring to FIG. 11, the swing driving section 20 of the roller assembly 100 of the present invention has two rows of rollers 1; and the two rows of rollers 1 of the swing driving section 20 may be rotated in synchronization with the first driving section 10 and the second driving section 30, respectively, or the two rows of rollers 1 may be rotated in synchronization according to a predetermined program.

Referring to fig. 12-a, the first driving area 10 and the second driving area 30 respectively drive the two side forward bags 200; the two rows of rollers 1 in the swing drive zone 20 rotate in synchronism to drive the central forward pack 200.

Referring to fig. 12 b, the two rows of rollers 1 of the swing driving section 20 are rotated in synchronization with the first driving section 10 and the second driving section 30, respectively, to drive two rows of transversely disposed bales 200, respectively.

The six-flower stack can be disassembled, and the five-flower stack can also be disassembled.

Referring to fig. 13-a, the first driving area 10 and the second driving area 30 respectively drive the two side forward bags 200; the two rows of rollers 1 in the swing driving area 20 rotate synchronously to drive the middle forward luggage 200; then, the two rows of rollers 1 of the swing driving area 20 rotate synchronously with the first driving area 10 and the second driving area 30 respectively to drive two transversely placed bales 200 respectively.

Referring to fig. 13-b, the two rows of rollers 1 of the swing driving section 20 rotate synchronously with the first driving section 10 and the second driving section 30, respectively, to drive two transversely placed parcels 200, respectively; then the first driving area 10 and the second driving area 30 respectively drive the two side forward bags 200; the two rows of rollers 1 in the swing drive zone 20 rotate in synchronism to drive the central forward pack 200.

Those skilled in the art can preset a corresponding driving program in the control unit to control the roller assembly 100 to perform a corresponding driving manner according to the actual shape of the stack during production.

Referring to fig. 14, 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.

In summary, the present invention provides an array type bag shifting mechanism, which divides a roller of an array into a first driving area, a swing driving area and a second driving area; the rollers in each driving area rotate according to a preset program to stir the goods packages to be led out one by one, and the goods packages quickly fall onto equipment in the next procedure under the action of gravity. In the unstacking process, a goods package is standby at the outlet position all the time, and the package falling action is continuous and compact; the postures of the package stack and the roller assembly do not need to be adjusted during unstacking; therefore, the time for unstacking is greatly reduced, and the unstacking efficiency is improved.
