[0025] During the bag stacking process, the bag stack that needs to be aligned is placed on the bag conveying mechanism 1, and the bag conveying mechanism 1 drives the bag stack to move backward until it is blocked by the bag blocking mechanism 2. The bag conveying mechanism 1 continues to operate so that the bag stack is aligned in the conveying direction under the blocking action of the bag blocking mechanism 2. Thereafter, the bag pushing and aligning mechanism 3 squeezes the side of the bag stack to finally complete the alignment of the bag stack.

The feeding belts are arranged at intervals to form a channel for the comb teeth in the bag stack transfer tray to pass through. When placing the bag stack, the bag stack transfer tray descends and the comb teeth pass through the interval space between the feeding belts, thereby stably placing the bag stack on the feeding belts.

[0027] In practice, the bag conveying mechanism 1 uses a plurality of bag conveying belts arranged in parallel, and each bag conveying belt is connected to the feeding belt in an alternating manner.

[0028] In implementation, the feed belt includes two side baffles 6 arranged opposite to each other, a driving wheel 7, a tensioning wheel 8 and a telescopic rod 9 extending outward are arranged between the side baffles 6, a driven wheel 10 is arranged at the end of the telescopic rod 9, and a synchronous belt 11 is arranged between the driving wheel 7, the tensioning wheel 8 and the driven wheel 10; in a specific implementation, the telescopic rod 9 may include a fixed rod fixed between the side baffles 6, a floating rod movably inserted in the fixed rod, and a compression spring is arranged between the fixed rod and the floating rod.

[0031] During implementation, the bag pressing mechanism 12 includes a vertically arranged bag pressing cylinder 20, the end of the piston rod of the bag pressing cylinder 20 is hinged with a joint 21, a connecting rod seat 22 is arranged on the bag pressing cylinder 20, a connecting rod 23 is hinged between the connecting rod seat 22 and the joint 21, and a pressing fork 24 is arranged at the end of the joint 21; when the piston rod of the bag pressing cylinder 20 is extended, the joint 21 is driven to move, and during the movement, the joint 21 is rotated under the action of the connecting rod 23, thereby driving the pressing fork 24 to rotate to the upper side of the bag stack.

[0032] The bag pushing and aligning mechanism 3 can be implemented by using a bag pushing cylinder and a bag pushing plate arranged on the piston rod of the bag pushing cylinder.

[0033] During implementation, the bag blocking mechanism 2 is straddled at the discharge end of the bag conveying mechanism 1, a bag sorting and conveying mechanism 25 is arranged at the rear side of the discharge end of the bag conveying mechanism 1, and the bag dividing mechanism 4 moves back and forth between the bag conveying mechanism 1 and the bag sorting and conveying mechanism 25; the bag sorting and conveying mechanism 25 has the same structure as the bag conveying mechanism 1, the discharge end of the bag sorting and conveying mechanism 25 is connected with the discharge mechanism 26, the feeding end of the bag sorting and conveying mechanism 25 is straddled with the bag blocking mechanism 2, the bag pushing and aligning mechanisms 3 and the bag pressing mechanisms 12 are arranged on both sides of the bag sorting and conveying mechanism 25, and a bag lifting mechanism 13 is arranged in the bag sorting and conveying mechanism 25.

[0034] In a specific implementation, the discharge mechanism 26 has the same structure as the feed mechanism 5; an alignment baffle 28 is provided at the rear end of the top support block 16 in the bag lifting mechanism 13 in the bag sorting and conveying mechanism 25; the bag blocking mechanism 2 provided on the bag sorting and conveying mechanism 25 can be provided as a sliding structure along the bag conveying direction and driven by an alignment cylinder 27; after the bag stack is transferred from the bag conveying mechanism 1 to the bag sorting and conveying mechanism 25, the bag pushing and alignment mechanism 3, the bag blocking mechanism 2 and the alignment baffle 28 in the bag sorting and conveying mechanism 25 cooperate with each other to realize reciprocating squeezing of the bag stack from the four sides of the bag stack, thereby completing the re-alignment of the bag stack and ensuring the neatness of the bag stack delivered to the next workstation.

[0035] During implementation, the bag conveying mechanism 1 and the feeding mechanism 5 can be synchronously driven by the same power source, and the bag sorting and conveying mechanism 25 and the discharging mechanism 26 can be synchronously driven by the same power source, which can achieve synchronous driving while saving occupied space.

[0036] In practice, the bag distributing mechanism 4 includes relatively arranged guide rails 29 , between which a movable frame 30 is slidably arranged, on which a suction cup cylinder 31 is vertically arranged, and on which a suction cup 32 is arranged on the piston rod of the suction cup cylinder 31 .

[0037] A specific working process of the bag stack splitting and sorting device of the utility model includes:

[0038] S1. A bag stack is formed by stacking a number of packaging bags. The task of the bag stack splitting and sorting device is to split and sort the bag stack handed over to the feeding mechanism 5, and then output it through the discharging mechanism 26. The stack splitting and sorting device can be arranged as a multi-layer structure, and the structure of each layer is the same. While the bag stack on a certain layer of the device is being split and sorted, the other layers can also receive the bag stack and split and sort the bags at the same time. This design greatly improves the work efficiency of bag stack splitting and sorting. In this example, one layer is taken as an example for explanation.

[0039] S2. A receiving tray for transferring bag stacks is arranged at the front side of the feeding mechanism 5. The receiving tray can complete lifting and rotating actions, and the receiving tray is in the shape of comb teeth so that it can pass through the gaps between the feeding belts in the feeding mechanism 5. When the receiving tray receives the bag stack placed from the outside, it rotates to the top of the feeding mechanism 5, and then the receiving tray descends to place the bag stack on the surface of the feeding mechanism 5; the bag stack is sent to the bag conveying mechanism 1 by the feeding mechanism 5, and the bag conveying mechanism 1 continues to convey the bag stack backwards until it is blocked by the bag blocking mechanism 2;

[0040] S3. The driving cylinder 18 in the bag lifting mechanism 13 acts to lift the stack of bags off the surface of the bag conveying mechanism 1 through the top support block 16. The bag pressing mechanism 12 acts, and through the cooperation of the pressing cylinder 20 and the connecting rod 23, the pressing fork 24 swings above the stack of bags without contacting the stack of bags. Then, high-pressure gas is ejected through the high-pressure nozzle 19 to blow the stack of bags off the top support block 16. Since the stack of bags is restricted by the bag pressing mechanism 12, it will not be scattered. At this time, the moving nozzle of the bag pushing and aligning mechanism 3 realizes the preliminary alignment of the stack of bags. After alignment, the high-pressure nozzle stops jetting, the bag pushing and aligning mechanism 3 stops acting, and the bag pressing mechanism 12 resets;

[0041] S4. The bag separating mechanism 4 acts to grab the uppermost packaging bag in the stack of bags. During the grabbing process, since the bag lifting mechanism 13 is in the state of lifting the stack of bags off the bag conveying mechanism 1, the suction cup 32 will not press on the bag conveying mechanism 1 when sucking the packaging bag, ensuring the service life of the bag conveying mechanism 1. After the grabbing is completed, the bag separating mechanism 4 moves the grabbed packaging bag to the bag arranging and conveying mechanism 25. At this time, the bag lifting mechanism 13 in the bag arranging and conveying mechanism 25 is also in the raised state, so as to place the packaging bag on the top support block 16;

[0042] S5. During the process of the bag separating mechanism 4 transferring the packaging bags in the stack of bags to the station of the bag arranging and conveying mechanism 25, after each packaging bag transfer task is completed, the bag pressing mechanisms 12 on both sides of the bag arranging and conveying mechanism 25 act to swing the pressing fork 24 above the stack of bags. Correspondingly, the high-pressure nozzle 19 in the bag lifting mechanism 13 in the bag arranging and conveying mechanism 25 ejects high-pressure gas to blow the packaging bag off the top support block 16. At this time, the bag pushing and aligning mechanism 3 and the bag blocking mechanism 2 on one side of the bag arranging and conveying mechanism 25 act simultaneously. Under the mutual cooperation of the bag pushing and aligning mechanism 3, the bag blocking mechanism 2 and the alignment baffle 28, the stack of bags is reciprocally squeezed from the four sides of the stack of bags to complete the re-alignment of the stack of bags;

[0043] S6. After completing the transfer and re-alignment tasks of the entire stack of bags, the bag lifting mechanism 13 in the bag arranging and conveying mechanism 25 resets to place the stack of bags on the bag arranging and conveying mechanism 25. The re-aligned stack of bags is sent out through the bag arranging and conveying mechanism 25 and the discharging mechanism 26. Thus, the splitting and arranging work of a stack of bags is completed.

[0044] The solution provided by the embodiment of the present invention can autonomously complete the tasks of splitting, arranging and conveying the stack of bags without human intervention, effectively solving the problems of large splitting difficulty and low arranging efficiency during the splitting and arranging process of the stack of bags, and thus bringing significant economic benefits to the enterprise.

[0045] The above are only the preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
