[0001] The present application relates to the technical field of office equipment, in particular to a paper automatic turnover device. BACKGROUND

[0002] Government agencies, institutions, large and medium-sized enterprises and other organizations produce a large number of paper files that need to be archived in daily work. In order to better archive and manage paper files, it is usually necessary to electronically process paper files, which mainly obtains electronic files corresponding to paper files through printing coding (referred to as coding, the same below) and imaging processing of paper files, so as to facilitate subsequent query and use.

[0003] In order to meet the needs of the above-mentioned coding of paper files according to page numbers, paper turnover mechanisms need to be set in existing paper file processing equipment. For example, the patent document with publication number CN218477317U discloses a structure for turning over paper after coding, and its turnover process is as follows: paper is conveyed from the top into the turnover mechanism and conveyed from the bottom of the turnover mechanism. Each paper file is equivalent to a 180-degree turnover, and the page numbers of the paper are sequentially increased from the bottom to the top, so as to realize effective sorting of the paper. Although this turnover structure has good turnover sorting effect, the turnover structure is composed of a C-shaped structure composed of an inner paper guide plate and an outer paper guide plate, which has the technical problems of complex structure, high cost and easy paper jamming due to long paper running path.

DETAILED DESCRIPTION

[0030] Example 1

[0031] As shown in Figure 1 , 2 , an automatic paper turnover device comprises a frame 1, which is of a conventional structure and specifically comprises two facing fixed support plates. The upper portion of the frame 1 is fixed with a paper feeding mechanism 2 for turning the paper downward from the horizontal direction, and the lower portion of the frame 1 is fixed with a paper receiving mechanism 3 for receiving the turned paper. A guide mechanism is fixed between the paper feeding mechanism 2 and the paper receiving mechanism 3 through the frame 1, and is used to guide the turned paper output by the paper feeding mechanism 2 to continuously and stably enter the paper receiving mechanism 3.

[0032] It should be noted that, in order to ensure better paper turnover effect, the lower end of the paper is inclined to the left as shown in Figure 1 when the paper feeding mechanism 2 outputs the paper downward, that is, the paper is output by the paper feeding mechanism 2 in a left-inclined manner, so as to ensure that the paper is stably turned over to the paper receiving mechanism 3 under the action of the guide mechanism.

[0033] As shown in Figure 1 , 2 , the paper feeding mechanism 2 comprises a conveying roller set and a turning guide assembly 4. The conveying roller set comprises an upper conveying roller 5, a lower conveying roller 6 and a turning conveying roller 7. The upper conveying roller 5 is located directly above the lower conveying roller 6, and the upper conveying roller 5 and the lower conveying roller 6 cooperate to form a horizontal conveying structure. The paper can be output horizontally from left to right in the direction shown in the figure under the action of the upper conveying roller 5 and the lower conveying roller 6. The turning conveying roller 7 is located obliquely downward of the output end of the horizontal conveying structure, and the turning conveying roller 7 and the lower conveying roller 6 cooperate to form a downward turnover conveying structure. In addition, the axis connecting line between the lower conveying roller 6 and the turning conveying roller 7 in the downward turnover conveying structure forms an angle of 15-45 degrees with the horizontal plane. Through the cooperation of the turning conveying roller 7 and the lower conveying roller 6 with the specific angle, the horizontally output paper can be turned downward and output leftward, so as to realize the automatic turnover of the paper. The turning guide assembly 4 is located between the upper conveying roller 5 and the turning conveying roller 7, and is used to guide the paper output by the horizontal conveying structure to turn downward and enter the downward turnover conveying structure, so as to ensure the stable turning of the paper.

[0034] It should be noted that the upper conveying roller 5, the lower conveying roller 6 and the turning conveying roller 7 rotate synchronously under the action of the driving mechanism, and the horizontal conveying structure and the downward overturning conveying structure share the lower conveying roller 6, which has the advantages of simple structure and short conveying path.

[0035] As shown in Figure 1 , 2 , the turning guide assembly 4 comprises an overturning member 8, a fixing member 9 and a guide plate 10 for guiding the paper to turn downward. The fixing member 9 is two L-shaped structural members, one side of each of which is fixed on the rack 1, and the other side of each of which is provided with a through hole. The overturning member 8 is also L-shaped, one side of which is detachably fixed in the through hole by a pin or the like, and the other side of which is fixedly connected with the guide plate 10. The fixed guide plate 10 is located between the upper conveying roller 5 and the turning conveying roller 7, and can guide the paper output by the horizontal conveying structure to turn downward and enter the downward overturning conveying structure. Since the overturning member 8 and the fixing member 9 are detachably connected, when a paper jam occurs in the device, the overturning member 8 can be first detached from the fixing member 9, and then the guide plate 10 can be overturned to quickly handle the paper jam.

[0036] Preferably, the embodiment is provided with an arc-shaped part with an arc of 100-160 degrees in the middle of the length direction of the guide plate 10, the concave surface of which faces the downward output roller, and the arc can be 120 degrees or can be set according to actual needs. In actual application, the guide plate 10 can guide the front end of the paper to turn smoothly through the arc-shaped part, avoiding paper jam caused by the front end being pressed against and unable to continue moving, thereby ensuring that the paper output by the horizontal conveying structure can smoothly turn and enter the downward overturning conveying structure.

[0037] As shown in Figure 1 , 2 , the paper receiving mechanism 3 comprises a paper receiving box 11 and a paper receiving guard plate 12, the paper receiving box 11 is fixed by the rack 1, and the paper receiving guard plate 12 is inclinedly arranged in the paper receiving box 11. The paper receiving box 11 and the paper receiving guard plate 12 cooperate to receive the overturned paper. In the direction shown in the figure, the paper receiving box 11 comprises a front side, a rear side, a left side and a right side, the heights of the front side, the rear side and the left side are the same, and the height of the right side is slightly lower. The bottom end of the paper receiving guard plate 12 is located in the paper receiving box 11, and the middle part is supported on the right side, so as to be inclinedly arranged in the paper receiving box 11, and the inclination angle of the paper receiving guard plate 12 is preferably 45 degrees. It should be noted that the paper receiving guard plate 12 can be fixed in the paper receiving box 11 or directly placed in the paper receiving box 11.

[0038] In addition, the embodiment preferably has two outwardly flared side paper guide plates 13 on the side surfaces (front side surface and rear side surface) of the receiving paper box 11 on both sides of the receiving paper guard 12, and the two side paper guide plates 13 are at least the same height as the lower end of the guide mechanism or at least higher than the lower end of the guide mechanism, so as to constrain the paper output by the paper conveying mechanism 2 and make the paper accurately enter the receiving paper box 11.

[0039] As shown in Figure 1 , 2 , the embodiment can be directly installed at the output end of the existing conventional code scanning equipment in actual application, such as the output end of the equipment disclosed in the patent document CN116552140A. The working process is as follows:

[0040] After the paper enters the horizontal conveying structure, the paper is horizontally output under the driving action of the upper conveying roller 5 and the lower conveying roller 6. Then, under the action of the guide plate 10, the front end of the paper is flipped downward to enter the downward flipping conveying structure, and is obliquely output to the left and downward under the driving action of the lower conveying roller 6 and the turning conveying roller 7. When the paper is output to the downward flipping conveying structure, the front end of the paper is orderly dropped onto the receiving paper guard 12 under the guiding and restraining action of the guide mechanism and the side paper guide plate 13, at this time, the bottom end of the paper is supported by the bottom surface of the receiving paper box 11, and the flipping of the paper is completed in this way. The subsequent paper is sequentially flipped and arranged on the receiving paper guard 12 (i.e., the page number of the lowermost page of the paper is small, and the page number is sequentially increased upward), that is, the flipping and sorting of the paper are completed, and when the conveying of all the papers is completed, the papers are flipped by 180 degrees along the long edge of the paper by manual operation, and the paper with the page number sequentially arranged from small to large and sorted is obtained.

[0041] In summary, in actual application, the front end of the paper is just output to the horizontal conveying structure, that is, the paper is flipped downward to enter the downward flipping conveying structure under the guiding action of the guide plate 10, so that the overall structure is simpler, and the running path of the paper is shorter, thereby having the advantages of lower cost and less paper jamming.

[0044] As shown in Figure 1 , the guide mechanism includes an upper paper guide plate 14 and a lower paper guide plate 15 fixedly inclined on the frame 1, and the upper paper guide plate 14 is inclined at an angle of 60-105 degrees with the horizontal plane, and the lower paper guide plate 15 is inclined at an angle of 50-100 degrees with the horizontal plane. In order to better guide the paper to accurately enter the receiving paper mechanism 3, the embodiment preferably has an inclination angle of 85 degrees for the upper paper guide plate 14 and an inclination angle of 70 degrees for the lower paper guide plate 15.

[0045] Preferably, in order to count the number of turned paper, the embodiment is provided with a through hole in the middle of the lower paper guide plate 15, and a sensor 16 is installed in the through hole, which is specifically installed on the left side of the lower guide plate, and can detect the number of turned paper through the through hole.
