Specific embodiments

[0024] The embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the present invention and are not restrictive.

[0025] The embodiment of the present invention provides a flip - type automatic paper loading machine. As Figures 1 to 6 shown, the flip - type automatic paper loading machine of this embodiment includes the following components arranged in the feeding order: machine platform 1, paper feeding device 4, flipping device 7, paper pushing device 8, and receiving device 9. The paper feeding device 4 is arranged on the machine platform 1, the flipping device 7 is arranged at the discharging end of the paper feeding device 4, the paper pushing device 8 is used to push the flipped paper stack out, and the receiving device 9 is used to receive the paper stack in the subsequent process. The paper stack is conveyed through the paper feeding device 4, flipped by the flipping device 7, and then pushed by the paper pushing device 8 to the receiving device 9 that receives the paper stack in the subsequent process. The flipping device 7 includes a flipping assembly 71 and a flipping driving mechanism (not shown in the figure) for driving the flipping assembly 71 to flip, and the flipping driving mechanism can be realized by a servo motor.

[0026] As Figures 3 to 6 shown, the paper feeding device 4 includes a paper pushing air cylinder 3, a main pushing plate 5, and a side pushing plate 6, and the main pushing plate 5 is connected to the paper pushing air cylinder 3. The paper feeding device 4 may further include a support frame 41, a conveyor belt 42, and a plurality of conveying rollers 43. The conveyor belt 42 and the conveying rollers 43 are arranged on the support frame 41 and are located on the side where the conveying device 4 is connected to the flipping device 7. The paper stack reaches the conveying rollers 43 through the conveyor belt 42 and is then sent to the flipping device 7 by the conveying rollers 43.

[0027] The main pushing plate 5 and the side pushing plate 6 are arranged above the conveying rollers 43. The side pushing plate 6 is arranged parallel to the conveying rollers 43 and perpendicular to the main pushing plate 5. The side pushing plate 6 can be fixedly arranged on the conveying rollers 43 or arranged perpendicular to the conveying rollers 43 in a direction perpendicular to the conveying rollers 43 to prevent the paper stack placed on the conveying rollers 43 from falling.

[0028] A plate 44 may also be provided on the conveyor belt 42. The plate 44 may be fixed or movable. When the stack of paper on the conveyor belt 42 is deviated, the stack of paper is placed on the conveyor belt 42 and dropped through the plate 44.

[0029] In an alternative embodiment of the present invention, the flipping assembly 71 includes a carrying platform, two side pressing plates 73 and an upper pressing member; the two side pressing plates 73 are disposed on the carrying platform and are parallel to each other, and a space for receiving the stack of paper is formed between the two side pressing plates 73; the upper pressing member includes a plurality of upper pressing plates 74 and a plurality of cross beams 75 passing through between the plurality of upper pressing plates 74.

[0030] As Figure 4 shown, fixing structures 12 are provided on both sides of the machine table 1. The cross beam 75 passes through the plurality of upper pressing plates 74 and is connected to the fixing structures 12 on both sides of the machine table 1 and can rotate relative to the fixing structures 12. Among them, the plurality of upper pressing plates 74 can be arranged parallel to each other in the vertical direction, and there is a certain separation space between the upper pressing plates 74 in the vertical direction. Auxiliary plates 76 may also be provided on both sides of the flipping assembly 71, that is, near the fixing structures 12 on both sides of the machine table 1, so that the overall structure of the flipping mechanism 71 is more stable. It should be noted that the auxiliary plates 76 can be arranged opposite to the side pushing plates 6 of the paper feeding device.

[0031] The stack of paper from the paper feeding device 4 can be pressed by the side pressing plates 73 and the upper pressing member. The flipping drive mechanism of the flipping device 7 drives the cross beam 75 to rotate, thereby driving the entire flipping assembly 71 to rotate, so as to control the stack of paper to be flipped (the flipping angle is 180°) and then reach the paper pushing device 8. Optionally, the carrying platform of this embodiment may be formed by a plurality of parallel carrying shafts 72. There is a certain gap between the plurality of carrying shafts 72. The number of carrying shafts 72 is at least three, and the setting distance thereof can be adaptively adjusted according to the size of the stack of paper. This embodiment does not make any limitation in this regard.

[0032] In the actual working process, due to transportation requirements, the paper is not allowed to have friction. In this embodiment, by providing a flipping mechanism, the paper can be protected to prevent damage to the paper during the paper conveying process.

[0033] The paper pushing device 8 includes a paper pushing clamp arm 81 and a paper pushing drive mechanism (not shown in the figure) for driving the paper pushing clamp arm 81 to move. The flipping device 7 and the paper pushing device 8 are servo-driven. The paper pushing clamp arm 81 and the paper receiving clamp arm 91 need to return to the origin. After setting the initial position, 81 returns to the fixed position. After setting the paper receiving length according to the setting, the paper pushing clamp arm 81 and the paper receiving clamp arm 91 will automatically calculate the position and move to the position calculated by the program, so as to form a distance between the paper pushing and receiving that matches the set paper length.

[0034] As Figure 4As shown in the figure, two parallel racks 11 can be embedded in the upper inner sides of the fixing structures 12 on both sides of the machine table 1. The paper pushing device 8 further includes two first gears 82, and the two first gears 82 are respectively engaged with the two racks 11. The paper pushing driving mechanism drives the meshing actions formed by the first gears 82 at the left and right ends and the racks 11 by using a servo motor to achieve forward and backward movements. A first chromium rod 83 can be connected between the two first gears 82 to make the first gears 82 on its left and right sides move synchronously, and uniformly complete the forward and backward movements of the paper pushing device 8.

[0035] Optionally, as Figure 7 shown in the figure, fixing plates 84 are further connected to the first gears 82 on both sides of the paper pushing device 8. A square steel 85 is arranged between the fixing plates 84 on both sides for connection. A linear guide 86 is arranged on the square steel so that the pushing clamp arm 81 can slide left and right relative to both sides of the machine table 1. An air cylinder 87 is arranged above the pushing clamp arm 81 to drive the telescopic movement in the vertical direction to drive the pushing clamp arm 81 to achieve ascending and descending movements.

[0036] In addition, the receiving device 9 can include two second gears 92, and the two second gears 92 are respectively engaged with the racks 11 on both sides of the machine table 1. The two second gears are correspondingly engaged with the racks 11 to drive the paper receiving clamp arm.

[0037] A second chromium rod 94 can be connected between the two second gears 92 to make the second gears 93 on its left and right sides move synchronously, and uniformly complete the forward and backward movements of the receiving device 9.

[0038] In this embodiment, both the paper pushing clamp arm 81 of the paper pushing device 8 and the receiving device 9 for receiving the paper stack are in the form of clamp arms that cooperate with the paper stack. And a horizontal receiving hook 93 is arranged at the bottom of the receiving clamp arm 91 of the receiving device 9. The receiving hook 93 can form a receiving platform for placing the paper stack conveyed by the paper pushing device 8. During the paper stack transportation process, the starting positions of the paper pushing clamp arm 81 and the receiving clamp arm 91 are preset in advance, and at the same time, the moving stroke of the paper pushing clamp arm 81 is set. When the program triggers the paper pushing action, the motor of the paper pushing driving mechanism drives the rack 11 to move forward, thereby forming the forward pushing action of the paper pushing clamp arm 81. After the paper clamp arm 91 reaches the set position of the paper receiving device 9, it moves forward 50 mm. In order to separate the paper and avoid paper interference, after completely separating from the paper, the paper pushing clamp arm 81 and the paper receiving clamp arm 91 return to their respective initial positions to wait for the next paper pushing.

[0039] The receiving device 9 can receive the box gluing machine. After the paper cutting knife of the box gluing machine blocks the paper stack, the paper receiving clamp arm 91 is retracted to the initial position.

[0040] When the flip - type automatic paper loading machine of this embodiment is actually working, the paper feeding device 4 in the flip - type paper feeding device conveys the folded paper stack to a set position in a roller - conveying manner, and is pushed by the paper pushing cylinder 3 to the flipping device 7. The flipping drive mechanism of the flipping device 7 drives the flipping assembly 71 to flip the paper stack by 180 degrees. The flipped paper stack is pushed by the paper pushing device and the receiving device 9 for receiving the paper stack to output to the next processing station. The whole process realizes the automatic flipping and output after product paper loading, improves the production efficiency of product packaging, reduces the labor intensity and production cost, avoids the influence of human factors, and at the same time reduces the decline in the surface accuracy of the paper caused by friction loss, ensuring the quality of the product.

[0041] The above - mentioned is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above - mentioned embodiment. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
