When the cartons in the carton bin reach the specified number, the bottom of the carton bin opens, so that the stacked cartons fall to the carton conveying assembly 40 and are conveyed to the specified equipment.

[0082] In the present invention, after the cartons have completed the bonding process, they are stacked on a pallet to form a carton stack. The pallet conveying assembly 30 conveys the pallet and the carton stack placed on the pallet to the turntable assembly 20. The carton stack of the present invention is four in a layer, arranged in a field shape, thereby forming four stacks of stacked cartons. The turntable assembly 20 is used to rotate the pallet, and a single rotation of 90° allows the four stacks of stacked cartons to be rotated to the bottom of the paper feeding assembly 60 respectively.

The pallet conveying assembly 30 conveys the pallet and the carton stack placed on the pallet to the turntable assembly 20. The turntable assembly 20 rises and approaches the paper feeding assembly 60. The paper feeding assembly 60 conveys the cartons at the top to the carton bin in sequence. The cartons contact the micro switch 621 to realize counting. When the cartons in the carton bin reach the specified number, the bottom of the carton bin opens, so that the stacked cartons fall to the carton conveying assembly 40 and are conveyed to the specified equipment. Since the technical means of splitting, sorting and conveying the carton stack to another device is adopted, the technical problems of manual operation in the prior art, which are dangerous, consume high labor costs and affect production efficiency, are effectively solved, thereby realizing the technical effects of automatic destacking, automatic counting, reducing operation dangers and improving production efficiency.

[0096] In the utility model, the second lifting frame 51 and the frame 10, as well as the first sliding frame 52 and the second lifting frame 51 are all slidably matched by a guide rail slider structure. The second lifting frame 51 is lifted and lowered by a chain drive, and the first sliding frame 52 is horizontally slid by a screw mechanism. The stacking baffles 53 are located on opposite sides of the carton. The two stacking baffles 53 are driven to approach or move away from each other by the two first cylinders 54 respectively. The stacking pallets 55 are located at the bottom of the carton. During the stacking process of the cartons, the two stacking pallets 55 are located at the bottom of the carton to play a supporting role. When the cartons are stacked and transferred to the roller conveyor line 42, the two second cylinders 56 respectively drive the two stacking pallets 55 to move away from each other, so that the bottom opening of the carton bin is opened, and the carton can fall onto the roller conveyor line 42 through the bottom opening. After the cartons are counted and stacked to a certain height, the two first cylinders 54 respectively drive the two stacking baffles 53 to move toward and away from each other for multiple times, which is the same as the principle of the carton aligning component 45, that is, it plays the role of arranging and aligning the cartons in the carton bin.

[0097] In the embodiment of the present utility model, Figures 11 to 13 As shown, the carton carrying assembly 50 also includes a connecting frame 571, a guide roller 572, a guide plate 573, a fixed beam 574, a rotating beam 575, a paper feeding wheel 576 and a paper feeding motor 577, wherein the connecting frame 571 is arranged on the first sliding frame 52; the guide roller 572 is arranged on the side of the connecting frame 571 close to the frame 10; there are two guide plates 573, the two guide plates 573 are arranged on the connecting frame 571 and are symmetrically located on both sides of the guide roller 572, and the two guide plates 573 are in a trumpet shape; the fixed beam 574 is arranged on the first sliding frame 52; one end of the rotating beam 575 is rotatably connected to the fixed beam 574; the paper feeding wheel 576 is rotatably arranged at the other end of the rotating beam 575, and the paper feeding wheel 576 is located at the top of the guide roller 572; the paper feeding motor 577 is used to drive the paper feeding wheel 576, and the paper feeding motor 577 is arranged on the rotating beam 575.

[0098] It can be understood that when stacking cartons, that is, when the cartons are transported to the carton bin in sequence, the carton carrying assembly 50 is first raised to a height where the guide roller 572 is aligned with the top of the carton stack, so that when the paper feeding assembly 60 transports the carton at the top, the carton at the top is guided into the carton bin by the guide roller 572 and the paper feeding wheel 576. At the same time, during the paper feeding process, the height of the carton carrying assembly 50 remains unchanged, and the turntable assembly 20 continuously moves upward to ensure that the carton at the top can contact the paper feeding assembly 60. During the conveying process, the paper feeding motor 577 is located between the guide roller 572 and the paper feeding wheel 576, driving the paper feeding wheel 576 to rotate, so that the carton is conveyed toward the carton bin. The rotating beam 575 where the paper feeding wheel 576 is located is rotated with the fixed beam 574, thereby controlling the gap between the paper feeding wheel 576 and the guide roller 572, so that the cartons pass through in sequence. At the same time, the guide plates 573 located on both sides of the guide roller 572 also guide the conveying of the cartons, so that the cartons can smoothly pass through the guide roller 572 and the paper feeding wheel 576 and smoothly enter the carton bin.

[0099] In the embodiment of the present utility model, Fig.14 and Fig.15 As shown, the paper feeding assembly 60 includes a fixed frame 61, a second sliding frame 62, a belt conveyor mechanism 63 and a fan 65, wherein the fixed frame 61 is arranged on the top of the frame 10 and is located above the turntable assembly 20; the second sliding frame 62 can be horizontally slidably arranged on the fixed frame 61; the belt conveyor mechanism 63 is arranged on the second sliding frame 62, and the belt conveyor mechanism 63 has a conveying belt, the conveying belt is provided with adsorption holes, and an adsorption block 64 is provided in the middle of the conveying belt, and the lower end surface of the adsorption block 64 is close to the conveying belt, and the micro switch 621 is arranged on the second sliding frame 62 and is located on the side of the conveying belt; the fan 65 is arranged on the fixed frame 61, and the fan 65 and the adsorption block 64 are connected through a suction pipe.

[0100] It can be understood that the fan 65 realizes the effect of vacuum adsorption, so that when the belt conveyor mechanism 63 drives the carton to convey, the belt located below adsorbs the upper end surface of the carton, thereby avoiding the problem that the carton is separated from the belt and cannot be conveyed smoothly. At the same time, during the conveying process, every time a carton passes, the carton contacts the micro switch 621 to realize the counting function. The utility model realizes automatic counting in this way, and according to the set number, a specific number of cartons are transferred from the carton stack to the carton bin, thereby realizing the destacking of the carton stack and the stacking of the cartons.

[0101] In the embodiment of the present utility model, Fig.14As shown, the paper feeding assembly 60 further includes a paper shifting component 66, which includes a mounting seat 661, a shifting cylinder 662 and a shifting plate 663, wherein the mounting seat 661 is arranged on the fixing frame 61; the shifting cylinder 662 is arranged on the mounting seat 661; the shifting plate 663 is connected to the piston rod of the shifting cylinder 662; the shifting cylinder 662 drives the shifting plate 663 to shift the carton toward the direction of the belt conveyor mechanism 63. The paper shifting component 66 plays the role of auxiliary feeding, and is used to shift the carton in the opposite direction of the belt conveyor mechanism 63, and then convey the carton to the direction of the carton bin through the belt conveyor mechanism 63.

[0102] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
