Description

Technical Field

[0001] This invention relates to the field of book production, and in particular to a book cover flipping mechanism. Background Technology

[0002] During the processing of hardcover covers, after one side of the cover is glued to the book block, the side of the hardcover cover not glued to the book block needs to be flipped up. Subsequent processes then press this flipped-up side of the cover onto the top surface of the book block to complete the mounting process. Currently, the flipping mechanisms used to lift the unglued side of the cover typically only achieve the basic flipping, and usually require moving the cover a considerable distance to do so, resulting in low efficiency. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0004] This invention provides a shell-flipping mechanism, comprising:

[0005] frame;

[0006] A cover pressing assembly, comprising a pressing drive and a pressing wheel row mounted on the frame, wherein the pressing drive drives the pressing wheel row to move downward;

[0007] A cover-flipping assembly includes a guide bar arranged in a left-right direction. The guide bar is located beside the spine rollers and flips one side of the cover from horizontal to vertical.

[0008] The beneficial effects of the present invention are as follows: By combining the cover pressing ridge assembly and the cover flipping assembly, the cover forms a pre-crease as it passes through the cover pressing ridge assembly to fold the cover. At the same time, the pressing ridge rollers of the pressing ridge assembly press the cover, which makes it easy to apply pressure to the cover so that the unbonded side of the cover can be stably flipped up by the guide strip. The flipping mechanism has a simple structure and high efficiency.

[0009] As some sub-solutions of the above technical solution, the cover spine pressing assembly also includes multiple spine pressing rollers, which are longitudinally separated into two rows. The spine pressing rollers are all rotatably connected to the spine pressing roller row. The cover spine pressing assembly also includes a pushing assembly, which includes a horizontally reciprocating pusher.

[0010] As some sub-solutions of the above technical solution, the pushing component also includes a horizontal reciprocating component, a vertical reciprocating component, and a pushing frame. The horizontal reciprocating component is mounted on the frame, the vertical reciprocating component is mounted on the horizontal reciprocating component, the vertical reciprocating component is drivenly connected to the pushing frame, and the number of pushing flags is at least two, all of which are mounted on the pushing frame.

[0011] As a sub-solution of the above technical solution, the vertical reciprocating component is a cylinder.

[0012] As a sub-solution of the above technical solution, the number of the pushing flags is 4.

[0013] As a sub-solution of the above technical solution, the flipping mechanism also includes a cover auxiliary support strip, which is disposed on the side of the guide strip opposite to the ridge roller row, and the cover auxiliary support strip is inclined to the upper right.

[0014] As some sub-solutions of the above technical solution, the spine pressing roller includes a wheel frame, a rotating wheel, and a spring. The wheel frame is mounted on the spine pressing wheel row by the spring, and the rotating wheel is located at the bottom of the wheel frame.

Detailed Implementation

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0026] In the description of this invention, "several" means an indefinite quantity, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features. The use of "and / or" throughout the text indicates three parallel solutions; for example, A and / or B indicates a solution satisfied by A, a solution satisfied by B, or a solution satisfied by both A and B.

[0027] In the description of this invention, if there is a short phrase containing multiple parallel features, the modifier in the phrase defines the closest feature. For example, "B, C, and E connected to D are set on A" means that B is set on A, E is connected to D, and C is not defined. However, modifiers indicating the relationship between features, such as "interval setting" or "circular arrangement," do not fall into this category. Modifiers preceded by "all" define all features in the short phrase. For example, "B, C, and D are all set on A" means that B, C, and D are all set on A. In statements where the subject is omitted, the omitted subject is the subject of the preceding statement; that is, "A has B and includes C" means that A has B and A includes C.

[0028] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0029] The following is combined Figures 1 to 5 Embodiments of the present invention will be described.

[0030] This embodiment relates to a cover-flipping mechanism, including a frame 1, a cover spine pressing assembly, and a cover flipping assembly;

[0031] The cover pressing assembly includes a pressing drive 21 and a pressing wheel row 22 mounted on the frame 1. The pressing drive 21 drives the pressing wheel row 22 to move downward.

[0032] The cover flipping assembly includes a guide bar 31 arranged in the left-right direction. The guide bar 31 is located on the side of the spine roller row 22 and the guide bar 31 turns one side of the cover from horizontal to upright.

[0033] This flipping mechanism combines a cover pressing component and a cover flipping component, so that when the cover passes through the cover pressing component to form a pre-crease for folding, the pressing wheel row 22 of the cover pressing component presses the cover, making it easy to apply pressure to the cover so that the unbonded side of the cover can be stably flipped up by the guide strip 31. This flipping mechanism has a simple structure and high efficiency.

[0034] The top surface of the guide strip 31 is a curved surface that gradually twists from horizontal to right to vertical, so that the first side of the cover that is not glued to the book block turns from horizontal to vertical on the top surface of the guide strip 31, realizing the flipping of the un-glued side of the cover. By combining the cover spine pressing device and the cover flipping device, the cover forms a pre-crease as it passes through the cover spine pressing device to fold the cover. At the same time, the pressing action of the spine pressing wheel row 22 of the cover spine pressing device can easily apply pressure to the cover, so that the un-glued side of the cover can be stably flipped up by the guide strip 31. This flipping mechanism has a simple structure and high efficiency.

[0035] Furthermore, the cover spine pressing assembly also includes multiple spine pressing rollers 23, which are longitudinally arranged in two rows. Each spine pressing roller 23 is rotatably connected to the spine pressing roller row 22. The cover spine pressing assembly also includes a pushing assembly 4, which includes a laterally reciprocating pusher 41. By configuring two rows of spine pressing rollers 23, two indented creases can be formed on the cover to facilitate folding. However, since the pressure exerted by the spine pressing rollers 23 on the cover when forming the pre-press lines is very high, relying solely on conveyor belt friction conveying is insufficient to meet the requirements for cover conveying. Therefore, this solution also includes a laterally reciprocating pusher 41, which abuts against the side of the cover and pushes the cover to the right, reliably driving the cover past the spine pressing rollers 23 to form creases.

[0036] Furthermore, the pushing assembly 4 also includes a transverse reciprocating assembly 42, a vertical reciprocating assembly 43, and a pushing frame 44. The transverse reciprocating assembly 42 is mounted on the frame 1, and the vertical reciprocating assembly 43 is mounted on the transverse reciprocating assembly 42. The vertical reciprocating assembly 43 is drivenly connected to the pushing frame 44. The number of pushing flags 41 is at least two, and all pushing flags 41 are mounted on the pushing frame 44. The transverse reciprocating assembly 42 and the vertical reciprocating assembly 43 can be pneumatic push rods, electric push rods, hydraulic push rods, linear modules, linear modules, lead screw mechanisms, etc., and their main function is to provide the output end of linear motion. In this embodiment, both the lateral reciprocating component 42 and the vertical reciprocating component 43 are linear modules. The lateral reciprocating component 42 includes a lateral reciprocating slide rail extending laterally and a lateral reciprocating slide table sliding along the lateral reciprocating slide rail. The vertical reciprocating component 43 includes a vertical reciprocating slide rail extending vertically and a vertical reciprocating slide table sliding along the vertical reciprocating slide rail. The pusher 44 is fixed on the vertical reciprocating slide table. When the pusher 43 is activated, the longitudinal reciprocating drive component first drives the pusher 44 to move upward, raising the pusher flag 41 to the height of the cover. At this time, the pusher flag 41 is located to the left of the cover. Then, the lateral reciprocating component 42 moves the pusher flag 41 to the right, pushing the cover to the right a certain distance. Then, the vertical reciprocating component 43 drives the pusher 44 to descend, lowering the pusher flag 41 below the cover. At this time, the lateral reciprocating component 42 moves the pusher flag 41 to the left and resets it, thus completing one pushing action cycle. By continuously executing the pushing action cycle, the cover and the book block glued to the cover can be moved downstream, that is, to the device on the right, for further processing. In this embodiment, there are 4 push flags 41, which are arranged at equal intervals along the horizontal direction. The design of 4 push flags 41 can increase the frequency of pushing the cover.

[0037] The vertical reciprocating assembly 43 is a cylinder. Using a cylinder as the vertical reciprocating assembly 43 has the advantage of lower cost.

[0038] In this embodiment, the number of push flags 41 is four. The four push flags 41 are arranged at equal intervals in the horizontal direction, and the design of four push flags 41 can increase the frequency of pushing the cover.

[0039] Furthermore, the flipping mechanism also includes a cover support strip 5, which is disposed on the side of the guide strip 31 facing away from the pressure ridge wheel row 22, and is inclined to the upper right. This cover support strip 5 is used to support the portion of the cover extending beyond the guide strip 31, resisting downward bending deformation that may occur due to gravity as the cover is supported and upright by the guide strip 31. By limiting the maximum bending amplitude and deformation of the cover, the cover support strip 5 provides better protection for the cover.

[0040] Furthermore, the spine pressure roller 23 includes a roller frame, a rotating wheel, and a spring. The roller frame is mounted on the spine pressure roller row 22 via the spring, and the rotating wheel is located at the bottom of the roller frame. This structural arrangement of the spine pressure roller 23 allows it to be connected to the spine pressure roller row 22 via a spring. This reduces the chance of damage to the cover or the spine pressure roller 23 when it presses firmly against the cover.

[0041] In addition, a cover flattening mechanism is provided downstream of the flipping mechanism, that is, on the right side. The cover flattening mechanism includes a flattening driver 65 and a cover pressing head 66 driven by the flattening driver 65 to press down. The cover pressing head 66 is used to press down the book pages.

[0042] The cover flattening mechanism also includes a cover positioning driver 61 arranged longitudinally, a spine pusher 62 driven by the cover positioning driver 61, a first cover positioning corner block 63, and a second cover positioning corner block 64. Both the first cover positioning corner block 63 and the second cover positioning corner block 64 are mounted on the frame 1. Together, they form a U-shaped cover positioning groove with its opening facing the spine pusher 62. The cover moves up and down above the cover positioning groove. By configuring the longitudinally arranged cover positioning driver 61, spine pusher 62, top pressure driver, cover pressure head 66, first cover positioning corner block 63, and second cover positioning corner block 64, the cover flattening mechanism achieves reliable positioning of the cover and presses down the side of the cover that is upright to fit against the book block, thus completing the bonding between the cover and the book block. Specifically, the cover, which is glued to the book block on one side, is pushed by the pusher 41 between the spine pusher 62 and the first cover positioning corner block 63 and the second cover positioning corner block 64. Then, when the cover positioning driver 61 is activated, the spine pusher 62 pushes the cover towards the first cover positioning corner block 63 and the second cover positioning corner block 64 to achieve the positioning of the cover. After that, the top pressure driver is activated to drive the cover pressure head 66 to move downward, that is, to press the part of the cover that is not in contact with the book block towards the book block, so that both sides of the top surface of the cover are glued to the book block, thus completing the complete mounting of the cover and the book block.

[0043] The cover flattening mechanism also includes a pre-pressing strip, which is positioned between the cover positioning driver 61 and the guide strip 31, and is located above the spine push plate 62. The pre-pressing strip is inclined, with the inclination direction being backward and downward. By configuring this pre-pressing strip, when the cover moves to the right, the side of the cover that is turned up is folded downward to a certain extent in advance under the guidance of the inclined pre-pressing strip, so that the subsequent top-pressing driver action can press the cover firmly.

[0044] The top surface of the cover pressing head 66 is inclined, and the inclined direction of the cover pressing head 66 is downward along the direction away from the spine push plate 62. By setting the cover pressing head 66 in an inclined form, when the top of the cover is pressed, the inclined cover pressing head 66 can press the part of the cover that extends beyond the book block below the top surface of the book block, which to some extent counteracts the tendency of the cover to flip upward due to elasticity, thereby reducing the problem of the cover warping and deformation on the opening side.

[0045] The first cover positioning corner block 63 is L-shaped and includes a first positioning surface and a second positioning surface for positioning the two sides of the cover. A first pad 631 and a second pad 632 are respectively provided on the first and second positioning surfaces. The first pad 631 and the second pad 632 protrude from the cover positioning groove on the first and second positioning surfaces, respectively. The cover flattening mechanism also includes a cover pad 67, which is fixed to the frame 1. The first pad 631 and the second pad 632 are both located above the cover pad 67, and a cover protrusion groove 630 is provided between the first pad 631 and the second pad 632 and the cover pad 67. When sealing the book block, after the book block is placed on the hardcover cover, the edges of the cover usually protrude from the book block, providing better protection. In this design, a first pad 631 and a second pad 632 are configured on the first cover positioning corner block 63. Firstly, the first pad 631 and the second pad 632 form a cover protrusion groove 630 with the cover pad 67 on which the cover is placed. Thus, when the cover and book block are pushed together by the cover positioning driver 61 via the spine pusher 62, the portion of the cover protruding from the book block can precisely extend into the cover protrusion groove 630, while the book block is restrained by the first pad 631 and the second pad 632, ensuring that the spine pusher 62 does not push the book block and cover to be flush. Furthermore, when the cover pressing head 66 is driven by the flattening driver 65 to press down the upright side of the cover, the first pad 631 and the second pad 632 can also limit the depth of the press, thus preventing excessive tilting of the cover when it is pressed down at an angle by the first pad 631 and the second pad 632, which could lead to insufficient adhesion between the cover and the book block. In this embodiment, the second cover positioning corner block 64 and the first cover positioning corner block 63 are mirror-symmetrically arranged to ensure that the side of the cover positioned by the second cover positioning corner block 64 is also designed with a cover protrusion groove 630, ensuring that the protruding edge size between the book block and the cover is consistent, and the book block and cover are more aesthetically pleasingly packaged.

[0046] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present invention.
