[0001] The present invention relates to the technical field of book processing equipment, and more particularly, to a bookbinding device. Background Art

[0002] A book refers to a bound collection of books and texts. In a narrow sense, it is an aggregation of papers with words and images. The publication of a book requires complex processes such as design, typesetting, printing, and binding. Among them, applying a cover adhesive to the papers is one of the essential processes.

[0003] Currently, in the actual operation of applying a cover adhesive to papers, the operator needs to first place the neatly stacked papers into the paper gripper, and then, according to the actual thickness of the papers measured manually, manually push the cover to adjust the actual position of the cover to align the papers with the cover. Then, hot melt adhesive is applied to the back of the papers, and by pressing the papers and the cover tightly together, the cover adhesive of the papers is achieved. However, the method of manually pushing the cover to align the papers with the cover according to the actual thickness of the papers measured manually has problems of poor alignment accuracy between the papers and the cover and low efficiency of cover adhesive application.

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the mechanisms of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0028] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the present invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0029] In addition, terms such as "horizontal" and "vertical" do not require the components to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0030] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and defined, the terms "arranged", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the connection inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] Please refer to Figures 1 to 5 , the embodiment of the present application provides a binding device 100, which includes a frame 10, a paper clamping mechanism 20, a glue coating mechanism 40, and a pressing mechanism 50 respectively arranged on the frame 10. The paper clamping mechanism 20 is used to clamp the paper and drive the paper to move horizontally relative to the frame 10, so that the paper passes through the glue coating mechanism 40 and the pressing mechanism 50 in sequence. The glue coating mechanism 40 is used to apply glue to the spine of the paper, and the pressing mechanism 50 is used to place the cover and drive the cover to move vertically relative to the paper, so that the cover is pressed and fixed to the paper through the glue.

[0032] As Figure 4 and Figure 5 shown, the binding device 100 further includes a controller, a measurement sensor, and a first driving member respectively electrically connected to the controller. The measurement sensor is used to obtain the thickness signal of the paper. An adjustment block 52 is slidably arranged on the pressing mechanism 50. The adjustment block 52 abuts against the horizontal side of the cover. The first driving member is in transmission connection with the adjustment block 52. The controller is used to control the first driving member to drive the cover to move relative to the pressing mechanism 50 in the thickness direction of the paper through the adjustment block 52 according to the thickness signal.

[0033] As described above, during the operation of binding the cover to the paper using the binding device 100, the operator needs to first place the neatly stacked papers into the paper clamping mechanism 20. The paper clamping mechanism 20 can clamp the papers. At this time, the measurement sensor can obtain the thickness signal of the papers and send the thickness signal to the controller. The controller can receive the thickness signal and calculate the actual thickness of the papers according to a preset algorithm. The controller can control the first driving member to drive the cover relative to the pressing mechanism 50 to move along the thickness direction of the papers through the adjusting block 52, so as to align the papers with the cover. After the operator places the neatly stacked papers into the paper clamping mechanism 20, the paper clamping mechanism 20 can also drive the papers to move horizontally relative to the frame 10, so that the papers pass through the gluing mechanism 40 and the pressing mechanism 50 in sequence. When the papers pass through the gluing mechanism 40, the gluing mechanism 40 can apply glue to the spine of the papers. After the papers move to the pressing mechanism 50, the pressing mechanism 50 can drive the cover placed on the pressing mechanism 50 to move vertically relative to the papers, so that the cover is pressed and fixed to the papers through the glue. Compared with the prior art in which the thickness of the papers is measured manually and the position of the cover is adjusted manually, the binding device 100 can improve the alignment accuracy between the papers and the cover, and at the same time can also improve the efficiency of cover binding.

[0034] Exemplarily, the above-mentioned measurement sensor can be fixedly arranged on the frame 10 or the paper clamping mechanism 20, as long as the position of the measurement sensor does not interfere with the operation process of binding the cover to the papers. The controller controls the first driving member to drive the cover relative to the pressing mechanism 50 to move along the thickness direction of the papers through the adjusting block 52 and the paper clamping mechanism 20 to drive the papers to move horizontally relative to the frame 10, which can be carried out simultaneously or successively. Those skilled in the art should be able to make a reasonable selection and design according to the actual situation, as long as the adjustment of the actual position of the cover by the controller is completed before the papers move to the pressing mechanism 50 to avoid interference between the movements in the two directions. No specific limitation is made here.

[0035] The above alignment between the papers and the cover means that the center line of the papers along the thickness direction of the papers is aligned with the center line of the cover along the thickness direction of the papers, so that after the cover binding of the papers is completed, the sides of the papers (except the spine) in all directions can be respectively aligned with the corresponding sides of the cover, thereby improving the aesthetic degree of the book. It should be noted that the sides of the papers along the thickness direction of the papers and the sides of the cover along the thickness direction of the papers can be accurately controlled by controlling the horizontal movement stroke of the papers driven by the paper clamping mechanism 20 and by respectively arranging limit plates on both sides of the cover along the thickness direction of the papers (one of the limit plates can be fixed and the other limit plate can be flexibly adjustable). No further discussion is made here.

[0036] For example, the actual thickness of the paper obtained by the controller based on the thickness signal is c, the width of the paper in the vertical direction is x, the width of the cover in the thickness direction of the paper is y, and the relational expression (1) is satisfied: y = c + x×2. The distance between the side of the adjusting block 52 (abutting against the cover) and the center line of the paper clamping mechanism 20 is z, and the relational expression (2) is satisfied: That is The width x of the paper in the vertical direction, the width y of the cover in the thickness direction of the paper, the relational expression (1), and the relational expression (2) can all be input into the controller through the control terminal in advance. For example, the control terminal can be a physical button and / or a virtual button, and the virtual button can be set on the display screen of the frame 10. In addition, the controller can include a storage module to store the data and algorithms input by the operator.

[0037] Specifically, as Figure 1 and Figure 2 shown, in this embodiment, there are two paper clamping mechanisms 20, and the two paper clamping mechanisms 20 are arranged oppositely on both sides of the frame 10. Each paper clamping mechanism 20 includes a slider 21, a second driving member 22, and a clamping plate 23. A slide rail is fixedly arranged on the frame 10, the slider 21 is slidably arranged in the slide rail, the second driving member 22 is fixedly arranged in the slider 21, and the transmission shaft of the second driving member 22 extends out of the slider 21 and is in transmission connection with the clamping plate 23.

[0038] It should be noted that, for example, the frame 10 can include a base 11 and side plates 12 arranged on opposite sides of the base 11, and the slide rail can be arranged on the side plates 12. When the operator puts the neatly stacked papers into the paper clamping mechanism 20, the spine of the papers can be in close contact with the top surface of the base 11, so that the operator can clearly know that the papers have been placed in place. At the same time, it can also ensure that when the second driving member 22 drives the clamping plate 23 to clamp the papers, the papers in the paper clamping mechanism 20 can still remain neatly stacked. The above-mentioned second driving member 22 can be electrically connected to the controller, so that the controller can control the second driving member 22 to drive the clamping plate 23 to clamp the papers.

[0039] It should also be noted that the paper clamping mechanism 20 may further include a detection sensor electrically connected to the controller. The detection sensor is used to obtain the paper placement signal, and the controller is used to control the second driving member 22 to drive the clamping plate 23 to move along the thickness direction of the paper according to the placement signal, so that the clamping plates 23 of the two paper clamping mechanisms 20 cooperate to clamp the paper, thereby improving the automation degree of the bookbinding device 100. Exemplarily, the detection sensor may be fixedly arranged on the base 11 or the clamping plate 23, as long as the position of the detection sensor does not interfere with the operation process of covering the paper with glue. In addition, the paper clamping mechanism 20 may further include a third driving member electrically connected to the controller. The third driving member is in transmission connection with the slider 21. The controller may include a timing module, and the controller controls the third driving member to drive the slider 21 to move horizontally at a preset time interval according to the timing module.

[0040] In this way, after the operator places the neatly stacked papers into the paper clamping mechanism 20, the detection sensor obtains the paper placement signal, and the controller can control the second driving member 22 to drive the clamping plate 23 to move along the thickness direction of the paper according to the placement signal, so that the clamping plates 23 of the two paper clamping mechanisms 20 can cooperate to clamp the paper. At this time, the measurement sensor can obtain the thickness signal of the paper, and the controller can control the first driving member to drive the cover relative to the press-fitting mechanism 50 to move along the thickness direction of the paper through the adjusting block 52 according to the thickness signal, so that the paper is aligned with the cover. After a preset time interval, the controller then drives the slider 21 to move horizontally by controlling the third driving member (that is, the controller controls the first driving member to drive the cover relative to the press-fitting mechanism 50 to move along the thickness direction of the paper and the paper clamping mechanism 20 to drive the paper to move horizontally relative to the frame 10 are carried out successively), so that the paper clamping mechanism 20 can drive the paper to move horizontally relative to the frame 10, so that the paper can pass through the glue application mechanism 40 and the press-fitting mechanism 50 in sequence.

[0041] Specifically, as Figure 1 and Figure 3 shown, in this embodiment, the glue application mechanism 40 includes a glue box 41 fixedly arranged on the frame 10, a glue application roller 42 rotatably arranged in the glue box 41, and a scraping plate 43 movably arranged above the glue box 41. The glue agent is accommodated in the glue box 41. On the path where the paper moves horizontally relative to the frame 10, the glue application roller 42 is located at the front end of the scraping plate 43.

[0042] It should be noted that the above-mentioned glue - applying roller 42 is rotatably arranged in the glue box 41, which enables the glue - applying roller 42 to attach the adhesive in the glue box 41 to its surface during rotation, and at the same time, it can also come into contact with the spine of the paper, so as to perform the glue - applying operation on the spine of the paper. On the path where the paper moves horizontally relative to the frame 10, the glue - applying roller 42 is located at the front end of the scraping plate 43, which enables the scraping plate 43 to scrape the spine of the paper and the adhesive attached to the spine of the paper when the paper passes through the scraping plate 43, so as to ensure that there is enough and evenly - applied adhesive on the spine of the paper.

[0043] It should also be noted that the glue - applying mechanism 40 may further include a fourth driving member electrically connected to the controller. The fourth driving member is in transmission connection with the glue - applying roller 42. The controller is used to control the fourth driving member to drive the glue - applying roller 42 to rotate relative to the glue box 41, so as to avoid the glue - applying roller 42 being in a rotating state when no paper passes through, thus causing the consumption of the adhesive and the glue - applying roller 42.

[0044] The above - mentioned scraping plate 43 is movably arranged above the glue box 41, which enables the actual height of the scraping plate 43 to be flexibly adjustable, so as to adapt to papers of different thicknesses. For example, in some embodiments, fixing frames may be provided on both sides of the glue box 41. A plurality of slots with different heights are arranged vertically on the fixing frames. The two ends of the scraping plate 43 can be selectively clamped in the slots with different heights, so that the actual height of the scraping plate 43 can be adjusted.

[0045] In other embodiments, a first lifting assembly is arranged between the scraping plate 43 and the frame 10. The first lifting assembly includes two groups, and the two groups of the first lifting assembly are respectively arranged at the two ends of the scraping plate 43. The controller is electrically connected to the first lifting assembly and is used to control the first lifting assembly to drive the scraping plate 43 to move vertically relative to the glue box 41 according to the thickness signal, so as to improve the accuracy of the adaptive adjustment of the actual height of the scraping plate 43.

[0046] As the actual thickness of the paper increases, more adhesive is required on the spine of the paper to ensure more reliable fixation between the paper and the cover. Optionally, a standard thickness a of the paper and a standard height b1 of the scraping plate 43 are preset in the controller. The controller obtains the actual thickness c of the paper and the actual height d1 of the scraping plate 43 according to the thickness signal, and satisfies the relational formula (3): d1 = b1+(a - c)×0.0382, where 1mm ≤ c ≤ 60mm. For example, the standard thickness a of the paper is taken as 20mm, and the standard height b1 of the scraping plate 43 is taken as 2mm. When the actual thickness c of the paper is 40mm, the actual height d1 of the scraping plate 43 can be calculated according to the relational formula (3), and d1 is 1.236mm.

[0047] Preferably, the binding device 100 further includes a fluffing mechanism 30 disposed on the frame 10. Along the path where the paper moves horizontally relative to the frame 10, the fluffing mechanism 30 is located between the paper clamping mechanism 20 and the glue coating mechanism 40. The fluffing mechanism 30 is used to cut the spine of the paper to fluff the spine of the paper, so as to facilitate the application of the glue and ensure that the glue can adhere more firmly to the spine of the paper.

[0048] Specifically, as Figure 1 and Figure 5 shown, in this embodiment, the fluffing mechanism 30 includes a milling cutter rotatably disposed on the frame 10. A second lifting assembly is disposed between the milling cutter and the frame 10. The controller is electrically connected to the second lifting assembly and is used to control the second lifting assembly to drive the milling cutter to move vertically relative to the frame 10 according to the thickness signal, so that the actual height of the milling cutter is flexibly adjustable, so as to adapt to papers of different thicknesses. By controlling the second lifting assembly to drive the milling cutter to move vertically relative to the frame 10 by the controller, the accuracy when adjusting the actual height of the milling cutter for adaptation can be improved.

[0049] As the actual thickness of the paper increases, the required fluffing depth on the spine of the paper is deeper to ensure more reliable fixation between the paper and the cover. Optionally, a standard thickness a of the paper and a standard height b2 of the milling cutter are preset in the controller. The controller obtains the actual thickness c of the paper, the actual height d2 of the milling cutter according to the thickness signal, and satisfies the relational expression (4): d2 = b2 - (a - c) × 0.0618, where 1mm ≤ c ≤ 60mm. For example, the standard thickness a of the paper is taken as 20mm, the standard height b2 of the milling cutter is taken as 7mm. When the actual thickness c of the paper is 40mm, the standard height b2 of the milling cutter can be calculated according to the relational expression (4) to be 8.236mm.

[0050] Specifically, as Figure 1 、 Figure 4 and Figure 5 shown, in this embodiment, the pressing mechanism 50 includes a placement seat 51 slidably disposed on the frame 10. A third lifting assembly is disposed between the bottom of the placement seat 51 and the frame 10. The controller is electrically connected to the third lifting assembly and is used to control the third lifting assembly to drive the cover to move vertically relative to the paper through the placement seat 51; at this time, the top surface of the placement seat 51 is the bearing surface for placing the cover. The adjusting block 52 is slidably disposed on the placement seat 51, and it is required that the distance between the top surface of the adjusting block 52 and the frame 10 is greater than the distance between the top surface of the placement seat 51 and the frame 10, so that the side surface of the adjusting block 52 can abut against the horizontal side edge of the cover.

[0051] Furthermore, as Figure 1 、 Figure 4 andFigure 5 As shown, two clamping blocks 53 are slidably arranged on the placing seat 51. The two clamping blocks 53 are arranged at intervals, and a bearing surface for placing the cover is jointly formed on the side of the two clamping blocks 53 away from the placing seat 51. The cover moves relative to the paper in the vertical direction so that the top surface of the placing seat 51, the cover and the spine of the paper located between the two clamping blocks 53 are sequentially abutted. The clamping blocks 53 move relative to the placing seat 51 in the thickness direction of the paper so that the two clamping blocks 53 cooperate to clamp the cover and the paper. Thus, when the two clamping blocks 53 approach each other, the binding device 100 can bond the cover and the paper to complete the binding operation; the adjusting block 52 is arranged on one side of the clamping block 53, and it is necessary to make the distance between the top surface of the adjusting block 52 and the placing seat 51 greater than the distance between the bearing surface and the placing seat 51 so that the side surface of the adjusting block 52 can abut against the horizontal side of the cover.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
