[0057] Optionally, the stack packaging device includes a stack sorting and transporting mechanism, a plurality of parallel third conveying mechanisms, a second stack handling mechanism, a packaging box conveying mechanism and at least one stack pushing mechanism, wherein:

[0058] The stacking classification and transfer mechanism is configured to receive the bagged stacks sent by the stacking bagging device, and classify the bagged stacks with different detection results and send them to the corresponding third conveying mechanism;

[0059] A plurality of third conveying mechanisms are configured to respectively receive bagged stacks of a test result and convey the received bagged stacks to a feeding station;

[0060] The second stack handling mechanism is configured to pick up bagged stacks at the feeding stations of the plurality of third conveying mechanisms and to carry the bagged stacks to the stack pushing mechanism;

[0061] The packing box conveying mechanism is configured to convey the empty packing box to the stack pushing mechanism, and the stack pushing mechanism is configured to send the received stacks into the empty packing box on the packing box conveying mechanism. The stacks received in the same packing box are of the same type.

[0062] Multiple third conveying mechanisms receive stacks of a test result respectively. When the number of stacking groups carried on one of the third conveying mechanisms is the same as the number of storage spaces in the packaging box, the second stacking handling mechanism grabs the stacking at the feeding station of the third conveying mechanism and delivers it to the stacking pushing mechanism, which pushes the stacking into the packaging box. During this process, the third conveying mechanism continues to move the stacking to the feeding station for the second stacking handling mechanism to pick up. When the corresponding packaging box is full of stacking, the packaging box conveying mechanism moves the packaging box backwards and moves the next empty packaging box to the stacking pushing mechanism. The second stacking handling mechanism carries the stacking on the next third conveying mechanism whose stacking group number meets the conditions. The stacking is automatically loaded into the packaging box, and the whole process does not require manual participation, which greatly improves the stacking efficiency; saves manpower and reduces production costs to a certain extent.

[0063] Optionally, there are two sets of stack pushing mechanisms, and the second stack handling mechanism sends the grabbed stacks to the two sets of stack pushing mechanisms in sequence. When one set of stack pushing mechanisms receives the stacks sent by the second stack handling mechanism, the other set of stack pushing mechanisms pushes the received stacks into the empty packaging box on the packaging box conveying mechanism.

[0064] By setting up two sets of stacking pushing mechanisms, when one set of stacking pushing mechanisms receives stacking sheets, the other set of stacking pushing mechanisms pushes the received stacking sheets into an empty packaging box, so that the stacking operation does not need to wait, and the stacking efficiency is further improved.

[0065] Optionally, the bag opening of the stacked stack transported by the second stack transporting mechanism to the stack pushing mechanism faces the stack pushing mechanism and is flipped downward and attached to the lower surface of the bag body.

[0066] A loading platform is mounted on the base, and the loading platform is configured to carry the stacked sheets to be boxed;

[0067] The sliding seat is slidably mounted on the base along a first direction, the pushing member is mounted on one end of the sliding seat close to the bearing platform, and the second driving member is configured to drive the sliding seat to approach the bearing platform along the first direction, so as to push the stacked sheets on the bearing platform into the packaging box through the pushing member;

[0068] Two first support plates are slidably mounted on the sliding seat, the two first support plates are flush with the bearing surface of the bearing platform, and the two first support plates are configured to respectively hold up the portion of the stack protruding from the bearing platform so as to closely attach the bag opening of the stack to the bag body of the stack;

[0069] The third driving member is installed on the sliding seat, and the driving end of the third driving member is connected to the two first pallets. When the pushing member moves toward the packaging box, the third driving member is configured to drive the two first pallets to move in the opposite direction so that the first pallets are stationary relative to the stack.

[0070] The sliding seat is driven by the second driving member to approach the bearing platform, and the first support plate and the pusher on the sliding seat will follow the sliding seat to move relative to the stack on the bearing platform. If the first support plate moves relative to the stack, the stack will be driven to move, and the bag mouth is easy to loosen and disengage. Therefore, in order to avoid the first support plate from moving relative to the stack, while the second driving member is working, the third driving member will drive the first support plate away from the bearing platform, so that the first support plate is stationary relative to the stack, and only the pusher is close to the stack on the bearing platform. When the pusher abuts against the stack and the bag body, the bag mouth of the bag body will be stuck and cannot be loosened. At this time, the third driving member stops working, and the first support plate and the pusher push the stack into the packaging box under the drive of the second driving member. When one end of the stack enters the packaging box, the third driving member can continue to work, and finally the pusher protrudes from the first support plate to push the stack into the packaging box. By adopting the above means, when the stack is loaded into the packaging box, the bag mouth of the stack will not be loosened, avoiding subsequent manual correction, reducing the burden on personnel, and improving work efficiency.

[0071] Optionally, the stacking pushing mechanism further includes a lifting assembly and a lifting seat, the base is mounted on the lifting seat in a liftable manner through a plurality of guide rods, the lifting assembly is mounted on the lifting seat, the lifting end of the lifting assembly is connected to the base, and the lifting assembly is used to drive the base to move up and down;

[0072] The lifting component drives the base to rise and fall to a preset height each time, so that the stack on the support table is flush with one of the storage spaces in the packaging box, so that the pusher can push the stack on the support table into the corresponding storage space.

[0073] Through the cooperation of the lifting assembly and the base, the automatic lifting of the load-bearing platform is realized, and then the pushing piece can push the stacked sheets on the load-bearing platform into empty storage spaces at different heights, thereby improving the pushing efficiency of the stacked sheets.

[0074] Optionally, the packaging box conveying mechanism includes a conveying line and a turning mechanism, wherein:

[0075] The conveyor line is configured to convey the packaging box along a first direction, with the opening of the packaging box on the conveyor line facing upward;

[0076] At least one loading station is arranged outside the conveyor line, and the flipping mechanism is located between the conveyor line and the loading station. The flipping mechanism is configured to flip the packaging box on the conveyor line to the loading station, so that the opening of the packaging box after flipping and located at the loading station faces the stacking pushing mechanism;

[0077] At least one set of stacking pushing mechanism is arranged on the side of the packaging box conveying mechanism, each set of stacking pushing mechanism corresponds to a loading station, and the stacking pushing mechanism is configured to push the received stacking into the opening of the packaging box on the loading station;

[0078] The turning mechanism is also configured to turn over the packaging box filled with stacked sheets at the loading station, so that the packaging box filled with stacked sheets is turned over and returned to the conveying line.

[0079] Through the cooperation of the conveyor line and the flipping mechanism, the automatic conveying of the packaging box and the automatic flipping of the packaging box to the loading station or the conveyor line are realized, which not only facilitates the packing of the stacked sheets; but also during the transportation process of the packaging box filled with stacked sheets, the opening is always facing upward, which effectively prevents the stacked sheets in the packaging box from accidentally falling off during the transportation process.

[0172] Through the cooperation of the transverse driving member 396, the push member 397, the upper folding member 393, the lower folding member 395, the third clamping member 398 and the clamping cylinder 399, the folded edge of the material bag 50 loaded with the stacked sheets can be automatically smoothed on the lower surface of the material bag 50 to avoid the folded edge from loosening, thereby improving the folded edge quality.

[0173] The specific folding process of the folding mechanism 39 is as follows:

[0174] S1, the upper driving member 3920 drives the first sliding seat 3921 to rise along the moving seat 391, and the lower driving member 3940 drives the second sliding seat 3941 to descend along the moving seat 391, so as to drive the upper folding member 393 and the lower folding member 395 to separate.

The bag adsorption and conveying component 351 is configured to adsorb the upper bag surface of the topmost bag 50 in the bag storage component 350, and move the adsorbed bag to the bagging station M. When the bag adsorption and conveying component 351 adsorbs the upper bag surface of the bag 50, the lower bag surface of the bag 50 moves away from the upper bag surface by its own weight, so that the middle part of the open end of the bag 50 is opened.

[0184] The material bag storage assembly 350 is used to store a plurality of stacked material bags 50, and the material bag adsorption and transport assembly 351 adsorbs the upper bag surface of the uppermost material bag in the material bag storage assembly 350, and then transports the adsorbed material bag to the bagging station M, thereby providing a material bag feeding mechanism 30 with a simple structure and small space occupation. At the same time, the material bag adsorption and transport assembly 351 only adsorbs the upper bag surface of the material bag 50, so that the lower bag surface of the material bag 50 is separated from the upper bag surface by its own weight, so that the opening end of the material bag 50 is automatically opened, so that the bag support assembly 383 can enter the material bag 50 from the opening end of the material bag 50.

[0185] See also Figure 1 , Fig.17 , Fig.18and Fig.24 As shown, as an embodiment, the stack packaging device 40 includes a stack classification and transfer mechanism 41, a plurality of parallel third conveying mechanisms 42, a second stack handling mechanism 43, a packaging box conveying mechanism 44 and at least one stack pushing mechanism 45, wherein: the stack classification and transfer mechanism 41 is configured to receive the bagged stacks sent by the stack bagging device 30, and classify the bagged stacks with different test results and send them to the corresponding third conveying mechanism 42; the plurality of third conveying mechanisms 42 are configured to receive the bagged stacks with different test results respectively.

[0186] It should be noted that: Fig.24 The stack packaging device shown does not include the packaging box conveying mechanism 44 .

[0187] The stacks of a test result are received by multiple third conveying mechanisms 42 respectively. When the number of stacking groups carried on one of the third conveying mechanisms 42 is the same as the number of storage spaces in the packaging box 51, the second stacking handling mechanism 43 grabs the stacking at the feeding station of the third conveying mechanism 42 and sends it to the stacking pushing mechanism 45, and the stacking pushing mechanism 45 pushes the stacking into the packaging box 51. In this process, the third conveying mechanism 42 continues to move the stacking to the feeding station for the second stacking handling mechanism 43 to pick up. When the corresponding packaging box 51 is full of stacking, the packaging box conveying mechanism 44 moves the packaging box 51 backward, moves the next empty packaging box 51 to the stacking pushing mechanism 45, and the second stacking handling mechanism 43 carries the stacking on the next third conveying mechanism 42 whose stacking group number meets the condition. The stacking is automatically loaded into the packaging box 51, and the whole process does not require manual participation, which greatly improves the packing efficiency of the stacking, saves manpower, and reduces production costs to a certain extent.

[0188] As an embodiment, the stack pushing mechanism 45 is provided with two sets, and the second stack conveying mechanism 43 sends the grabbed stacks to the two sets of stack pushing mechanisms 45 in sequence. When one set of stack pushing mechanism 45 receives the stacks sent by the second stack conveying mechanism 43, the other set of stack pushing mechanism 45 pushes the received stacks into the empty packaging box 51 on the packaging box conveying mechanism 44.

[0189] By providing two sets of stacking pushing mechanisms 45, when one set of stacking pushing mechanisms 45 receives stacking sheets, the other set of stacking pushing mechanisms 45 pushes the received stacking sheets into the empty packaging box 51, so that the stacking operation does not need to wait, and the stacking efficiency is further improved.

[0190] Please refer to 18 to Fig. 20 As shown, as an embodiment, the bag opening of the stacked stack after being transported to the stack pushing mechanism 45 by the second stack transporting mechanism 43 faces the stack pushing mechanism 45 and is turned downward and attached to the lower surface of the bag body. The stack pushing mechanism 45 includes a bearing platform 450, a second driving member 451, a pushing member 452, a second base 453, a sliding seat 454, two first supporting plates 455 and a third driving member 456, wherein: the bearing platform 450 is installed on the second base 453, and the bearing platform 450 is configured to carry the stacked stack to be packed; the sliding seat 454 moves along the third direction ( Fig.17 The second driving member 451 is configured to drive the sliding seat 454 to approach the bearing platform 450 along the third direction, so as to push the stack on the bearing platform 450 into the packaging box 51 through the pushing member 452; the two first support plates 455 are slidably mounted on the sliding seat 454, and the two first support plates 455 are flush with the bearing surface of the bearing platform 450. The two first support plates 455 are configured to respectively hold up the parts of the stack protruding from the bearing platform 450, so as to make the bag mouth of the stack close to the bag body of the stack; the third driving member 456 is mounted on the sliding seat 454, and the driving end of the third driving member 456 is connected to the two first support plates 455. When the pushing member 452 moves toward the packaging box 51, the third driving member 456 is configured to drive the two first support plates 455 to move in the opposite direction, so that the first support plates 455 are stationary relative to the stack.

[0191] Specifically, the supporting platform 450 is configured to carry the stacks transferred by the second stack handling mechanism 43, the driving end of the second driving member 451 is connected to the pushing member 452, and the second driving member 451 is configured to drive the pushing member 452 to approach or move away from the supporting platform 450 to push the stacks on the supporting platform 450 into the opening of the packaging box 51 on the packaging box conveying mechanism 44.

[0192] When the above-mentioned stacking pushing mechanism 45 is working, the second driving member 451 first drives the sliding seat 454 to approach the supporting platform 450, and the first support plate 455 and the pushing member 452 on the sliding seat 454 will follow the sliding seat 454 to move relative to the stacking on the supporting platform 450. If the first support plate 455 moves relative to the stacking, the stacking will be driven to move, and the bag mouth will easily loosen and detach. Therefore, in order to prevent the first support plate 455 from moving relative to the stacking, while the second driving member 451 is working, the third driving member 456 will drive the first support plate 455 away from the supporting platform 450, so that the first support plate 455 is stationary relative to the stacking, and only the pushing member 452 is close to the stacking on the supporting platform 450. When the pusher 452 contacts the stack and the bag, the bag mouth of the bag will be stuck and cannot be loosened. At this time, the third driving member 456 stops working, and the first support plate 455 and the pusher 452 push the stack into the packaging box 51 under the drive of the second driving member 451. After one end of the stack enters the packaging box 51, the third driving member 456 can continue to work, and finally the pusher 452 protrudes from the first support plate 455 to push the stack into the packaging box 51. By adopting the above means, when the stack is loaded into the packaging box 51, the bag mouth of the stack will not be loosened, avoiding subsequent manual correction, reducing the burden on personnel, and improving work efficiency.

The second base 453 is mounted on the lifting seat 458 so as to be liftable via a plurality of guide rods. The lifting assembly 457 is mounted on the lifting seat 458, and the lifting end of the lifting assembly 457 is connected to the second base 453. The lifting assembly 457 is used to drive the second base 453 to be lifted and lowered. Each time, the lifting assembly 457 drives the second base 453 to be lifted and lowered to a preset height, so that the stack on the supporting platform 450 is flush with one of the storage spaces 510 in the packaging box 51, so that the pushing piece 452 can push the stack on the supporting platform 450 into the corresponding storage space 510.

[0196] Through the cooperation of the lifting assembly 457 and the second base 453, the automatic lifting of the support platform 450 is realized, and then the pushing member 452 pushes the stacked sheets on the support platform 450 into the empty storage spaces 510 at different heights, thereby improving the pushing efficiency of the stacked sheets.
