Description

Technical Field

[0001] The present invention relates to a book spine labeling device and its working method. Background Art

[0002] Books are an important way for the inheritance of human civilization and the dissemination of knowledge. With the development of human society, the volume of book publishing has reached new highs. The book purchases of major libraries have also reached new highs. Currently, a scientific book labeling system has been formed to achieve standardized, scientific, and information-based management of such a large number of books. However, the workload of physical processing for book labeling before new books are shelved in libraries is extremely huge. Due to the different sizes and thicknesses of books, and there are multiple different labeling areas on the same book, the book labeling processing flow is complex. In particular, it is difficult to paste the labels on the spine part in a standardized manner. The thicknesses of books are different, and the label needs to be pasted by fitting three surfaces. Moreover, for different books, the sizes of the three surfaces are different. Currently, manual methods are used for scanning each book one by one, printing labels, pasting protective films, and labeling books at different positions.

[0003] Manually pasting labels on the spines of such a large number of books one by one, on the one hand, seriously affects the efficiency of new book shelving and is not conducive to the exchange and inheritance of the latest culture; on the other hand, manual operation is not conducive to the standardization and unification of physical processing for book labeling, and even affects the accuracy of labels. Factors such as manual proficiency and fatigue have a certain impact on the stability of the quality of physical processing for book labeling, which is not conducive to scientific and standardized management of books. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a book spine labeling device and its working method, which not only has a reasonable structure but also can meet the labeling operations for the spines of books with different thicknesses.

[0005] To solve the above technical problem, the technical solution of the present invention is: It includes a label printer. Labels are intermittently pasted on the label tape output by the label printer. The end of the label tape is wound around a label tape pressure roller and fixedly connected to a tape take-up roller. A protective film pressure roller is pressed on the label tape pressure roller. A protective film is wound around the protective film pressure roller. The other end of the protective film is wound around a protective film roller shaft. An adhesive is provided on the opposite surface of the protective film in contact with the protective film pressure roller. The label is transported to the position between the label tape pressure roller and the protective film pressure roller and is attached to the protective film through the adhesive. The label tape and the protective film are partially attached between two crawler-type components after passing through the protective film pressure roller. A telescopic cutter and a flexible telescopic roller presser are sequentially provided along the vertical extension direction of the crawler-type components. A flexible centering device is provided directly above the flexible telescopic roller presser.

[0006] Further, the label is pasted with a protective film to form a label film. Two crawler-type assemblies are respectively located on both side edges of the adhesive side of the label film. The crawler-type assembly includes a crawler, and a driving wheel and a driven wheel that drive the crawler to rotate at the upper and lower ends of the crawler. The outer surface of the crawler is spaced with convex raised teeth along its conveying direction. The outer ends of the raised teeth are all arc-shaped to reduce the contact surface with the label film.

[0007] Further, the telescopic cutter is horizontally arranged on the non-adhesive side of the protective film. The telescopic cutter includes a cutter telescopic assembly and a cutter fixedly connected to the telescopic end of the cutter telescopic assembly.

[0008] Further, the flexible telescopic roller presser includes two flexible rollers. The upper and lower ends of the flexible rollers are respectively rotatably connected to two swing brackets. The ends of the two swing brackets away from the flexible rollers are hinged and rotatably connected within the axle center frame. The hinged ends of the two swing brackets are butted by torsion springs for resetting. The outer end of the axle center frame is driven to horizontally expand and contract by a labeling telescopic assembly. The hinged ends of the two swing brackets can be rotatably connected to the axle center frame through a vertical rotating shaft, and a torsion spring is sleeved on the vertical rotating shaft. The two ends of the torsion spring respectively abut on the two swing brackets to facilitate the swing and reset of the two swing brackets. In the reset state, the two swing brackets are in a parallel state.

[0009] Further, the flexible centering device includes a horizontally arranged flexible centering device telescopic assembly and a flexible centering block fixedly connected to the telescopic end of the flexible centering device telescopic assembly. The side surface of the flexible centering block facing the spine labeling is concave with a V-shaped centering groove. The V-shaped centering groove vertically extends through the flexible centering block. The end surface where the center of the V-shaped centering groove is located is coplanar with the central axis surface of the protective film cut by the telescopic cutter.

[0010] Further, the tape take-up roller, the protective film roller shaft, and the protective film pressing roller are all driven to rotate by different driving components, and the driving components can be motors.

[0011] A working method of a book spine labeling device is carried out according to the following steps: When the book is conveyed to the spine labeling station, the flexible centering block is extended through the centering device telescopic component to dock the spine in the V-shaped centering groove to be centered. Then, the label printer and each driving component are started synchronously. The label is detached from the label tape at the docking position of the label tape pressure roller and the protective film pressure roller and adhered to the protective film at intervals through glue. The edge of the formed label film adheres to the raised teeth of the two crawler-type components and moves vertically upward. When it moves to the flexible telescopic roller press station, the label printer and each driving component stop conveying synchronously, and the cutter is extended by the cutter telescopic component to cut between adjacent label films. The cutter telescopic component resets. Then, the labeling telescopic component drives the axle center frame to extend, and the two flexible rollers push the cut label film onto the spine for attachment. The flexible rollers continue to advance and swing toward both sides through the swing bracket to tightly paste the label film on the spine. After the labeling is completed, the labeling telescopic component resets, and the two swing brackets reset under the action of the torsion spring to complete the spine labeling. By this cycle, centering and labeling work can be carried out on book spines of different thicknesses, greatly improving the efficiency.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the automated method of flexible roller pressing, the combination of the protective film and the printed label is realized, and a protective film is attached to the surface of the book label, better ensuring the service life of the label; 2. The combination of the crawler-type transmission method and telescopic cutting realizes the stable conveying and independent separation of the label with the protective film; 3. The design of the flexible centering clamp meets the processing operations of the book spines of different thicknesses; 4. The design of the openable and closable roller pressing realizes the reliable pasting of the label with the protective film.

The crawler-type assembly includes a crawler and a driving wheel 703 and a driven wheel 704 that drive the crawler to rotate at the upper and lower ends of the crawler 702. Raised gear teeth 701 are spaced and protrude on the outer surface of the crawler along its conveying direction. The outer ends of the raised gear teeth are all arc-shaped to reduce the contact surface with the label film.

[0023] In an embodiment of the present invention, the cutter telescopic assembly, the labeling telescopic assembly, and the flexible centering device telescopic assembly are all connected and positioned with the overall bracket of the device (not shown in the figure).

The telescopic cutter includes a cutter telescopic assembly 111 and a cutter 112 fixedly connected to the telescopic end of the cutter telescopic assembly. The cutter telescopic assembly can be a cylinder or a hydraulic cylinder.

[0025] In an embodiment of the present invention, the flexible telescopic roll press includes two flexible rollers 101. The upper and lower ends of the flexible rollers are respectively rotatably connected to two swing brackets 102. One end of the two swing brackets away from the flexible rollers is hinged and rotatably connected inside a spindle frame 103. The hinged ends of the two swing brackets are butt-jointed by torsion springs for resetting. The outer end of the spindle frame is driven to horizontally expand and contract by a labeling telescopic assembly 104. The labeling telescopic assembly can be a cylinder or a hydraulic cylinder. The hinged ends of the two swing brackets can be rotatably connected to the spindle frame through a vertical rotating shaft, and a torsion spring is sleeved outside the vertical rotating shaft.

[0028] A working method of a book spine labeling device is as follows: When the book 13 is conveyed to the spine labeling station, the flexible centering block is extended through the centering device telescopic assembly to dock the spine in the V-shaped centering groove in the center. Then, the label printer and each driving component are started synchronously. The label comes off the label tape at the docking position of the label tape pressing roller and the protective film pressing roller and adheres to the protective film at intervals through glue. The edge of the formed label film adheres to the raised teeth of the two crawler-type components and moves vertically upward. When it moves to the flexible telescopic roll press station, the label printer and each driving component stop conveying synchronously, and the cutter is driven to extend by the cutter telescopic assembly to cut between adjacent label films. The cutter telescopic assembly resets. Then, the labeling telescopic assembly drives the spindle frame to extend, and the two flexible rollers push the cut label film onto the spine for attachment. The flexible rollers are continuously pushed to swing towards both sides through the swing brackets to tightly paste the label film on the spine. After the labeling is completed, the labeling telescopic assembly resets, and the two swing brackets reset under the action of the torsion springs to complete the spine labeling. By cycling in this way, the centering and labeling work can be carried out on book spines of different thicknesses, greatly improving the efficiency. As for the feeding and discharging of books, it can be completed through a conveyor belt, which is a general design and will not be elaborated here.
