Description

Technical Field

[0001] The invention belongs to the technical field of printing equipment, and in particular relates to a page turning device. Background Art

[0002] The library has a huge amount of books, and the workload of borrowing and returning books is large and prone to errors. In order to manage books more conveniently and efficiently, it is necessary to print collection codes, RFID tags or stamps on the pages of books. Before printing the collection code, RFID tag or stamp, it is often necessary to turn the cover 101, back cover or pages of the book 1. If the page turning is done manually, the labor intensity is very high and the production efficiency is greatly reduced. Therefore, it is urgent to develop an automatic page turning device.

[0003] In order to solve the above problems, the Chinese invention patent with authorization announcement number 107628436B discloses an automatic page turning mechanism, including a conveyor, a vacuum suction nozzle, a page turning action cylinder, a blocking cylinder, a page turning guide rod and a supporting guide plate. When turning pages, the unfolded book (page) with one side tilted is moved to the blocking cylinder through the conveyor, the blocking cylinder extends the baffle to block the book, the conveyor stops, the horizontally arranged page turning action cylinder pushes the vacuum suction nozzle to close to and suck the tilted book page, the page turning cylinder contracts, and the page falls to the page turning guide rod to achieve complete page turning.

[0004] Although the above patent can automatically turn pages of books, it has the following problems: (1) Figure 1 -A, the above patent is to turn the pages of the opened book 1 along the direction of arrow a, and before the book 1 enters the conveyor, the book 1 needs to be opened as shown in FIG. Figure 1 -A, it is impossible to completely turn the pages automatically without manual intervention; (2) In the above patent, after the page turning cylinder is retracted, the pages fall freely (the direction of the pages falling is Figure 1 a), when the free end of the page falls below the page turning guide rod, the page can be completely turned. Therefore, the page turning device disclosed in the patent can only turn the pages of thinner paper that can be bent back, and cannot turn the pages of harder paper that cannot be bent back (especially the cover); (3) The above patent cannot turn the book Figure 1 Turn the pages in the b direction. Summary of the invention

[0005] The object of the present invention is to provide a fully automatic page turning device capable of turning pages of books made of relatively hard paper.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A page turning device comprises a suction cup assembly, a first page turning auxiliary rod, a second page turning auxiliary rod and a third page turning auxiliary rod; the initial position of the first page turning auxiliary rod, the third page turning auxiliary rod and the suction cup assembly are at the page opening side, and the second page turning auxiliary rod is at the spine side; the third page turning auxiliary rod is at the downstream of the suction cup assembly; the first page turning auxiliary rod is used to push the cover or the book page above the third page turning auxiliary rod to the second page turning auxiliary rod;

[0008] It also includes a fifth mounting plate, and a first linear power mechanism for controlling the movement of the suction cup assembly, wherein the first linear power mechanism is slidably connected to the fifth mounting plate along the moving direction of the book;

[0009] It also includes a pushing mechanism for controlling the movement of the first page turning auxiliary rod.

[0010] The working principle of this technical solution is:

[0012] When turning pages, the first linear power mechanism controls the suction cup assembly to move downward and then upward, and the cover or book page tends to open upward under the action of the suction cup assembly, and then falls freely. At this time, since the book continues to move forward during the page turning process, the first linear power mechanism slides along the moving direction of the book and is connected to the fifth mounting plate, so the cover or book page that opens and falls again will fall on the third page turning auxiliary rod downstream of the suction cup assembly. Finally, the pushing mechanism controls the first page turning auxiliary rod to move out, and the first page turning auxiliary rod pushes the cover or book page above the third page turning auxiliary rod to the second page turning auxiliary rod.

The sliding structure between the third mounting plate 703 and the second slide rail mounting plate 1001 is the same as the sliding structure between the first mounting plate 701 and the second mounting plate 702, that is, the second slide rail mounting plate 1001 is slidably connected to the guide rail on the lower surface of the third mounting plate 703 through a slide rail slider. The free end of the second slide rail mounting plate 1001 is fixedly connected to the second page turning auxiliary rod 5 by bolts. The linear motion unit 1003 and the second slide rail mounting plate 1001 are linked by the fourth sliding plate 1002 (such as Figure 6 , the longitudinal section of the fourth sliding plate 1002 is L-shaped), the linear motion unit 1003 is started, and the linear motion unit 1003 drives the second page turning auxiliary rod 5 to move through the fourth sliding plate 1002 and the second slide rail mounting plate 1001.

The free end of the second page-turning auxiliary rod 5 is tilted upward, and the supporting strength of the second page-turning auxiliary rod 5 on the book 1 is optimal.

[0051] like Figure 4This embodiment also includes a third slide rail mounting plate 12 fixedly connected to the side of the conveying mechanism 2 by bolts. A sixth sliding plate 13 is vertically slidably connected to the third slide rail mounting plate 12. The longitudinal section of the sixth sliding plate 13 is an inverted L shape. An electric eye is welded on the sixth sliding plate 13. The electric eye can be a coaxial beam photoelectric sensor of model zr-q200N produced by Japan Ops opt page turning device-Ex) for measuring the thickness of the spine side 102. The electric eye can also be a sensor in the prior art.

[0054] When turning pages, the first linear power mechanism 303 controls the suction nozzle 301 to move downward and then upward through the suction nozzle mounting block 302. The cover 101, the back cover or the book page has a tendency to open upward under the action of the suction nozzle 301, and then falls freely. At this time, since the book 1 continues to move forward during the page turning process, the first linear power mechanism 303 is slidably connected to the fifth mounting plate 706 along the moving direction of the book 1, so the cover or page that is opened and falls again will fall on the third page turning auxiliary rod 6 downstream of the suction nozzle 301. Finally, the linear motion unit 1003 is started, and the linear motion unit 1003 drives the first page turning auxiliary rod 4 to move out through the fourth sliding plate 1002 and the second slide rail mounting plate 1001. The first page turning auxiliary rod 4 pushes the cover or page above the third page turning auxiliary rod 6 to the second page turning auxiliary rod 5 to achieve complete page turning. During the whole process, the pages of the book 1 move along Figure 1 Middle arrow b moves.

[0055] The page turning device provided in this embodiment can turn the cover and the pages, and is suitable for turning the covers and pages of hard paper continuously. Compared with the prior art that requires manual opening of the book 1, the page turning device provided in this embodiment can realize full automation in the page turning process.

The three sixth auxiliary rods 1503 are in a vertical array and are arranged along the conveying direction of the book 1 ( Figure 2 The sixth auxiliary rod 1503 prevents the (multiple) pages from falling back after turning the pages.

[0058] (2) The fourth mounting plate 705 is slidably connected to the third mounting plate 703 through the first slide rail mounting plate 708. A sliding structure is provided between the fourth mounting plate 705 and the first slide rail mounting plate 708. A sliding structure is provided between the first slide rail mounting plate 708 and the third mounting plate 703. The sliding structure between the fourth mounting plate 705 and the first slide rail mounting plate 708, and the sliding structure between the first slide rail mounting plate 708 and the third mounting plate 703 are the same as the sliding structure between the first mounting plate 701 and the second mounting plate 702.
