Description

Technical Field

[0001] The invention generally relates to the technical field of printed matter packaging, in particular to a book packaging line and books. Background Art

[0002] At present, the commonly used book and periodical packaging processes are saddle stitch packaging and glue binding, and there are basically only packaging equipment (packaging lines) suitable for these two packaging processes on the market.

[0003] Saddle stitching requires folding the paper into book signatures, and then putting the front and back signatures on top of each other like a saddle (called a saddle), and after all the signatures are saddled, the whole book (book blank) is saddle-stitched together to form a volume. Books and periodicals sealed with saddle stitching have the saddle stitches exposed, which affects the appearance. After long-term reading, the staples and pages are prone to fall off, and there is rust pollution. If used on books and periodicals for young children, there is also a risk of the young children being ingested or scratched by the staples.

[0004] The glue binding process requires folding paper into book signatures, then stacking the front and back book signatures neatly (called matching) and flattening and clamping them, then grinding and roughening the spine with a gear knife, and then applying glue on the surface of the spine that has been ground and roughened, and then wrapping the cover on the outside, so as to glue all the book signatures and the cover together and bind them into a book. The glue binding process generally requires the spine thickness to be more than 3mm. For books and periodicals with fewer pages, glue binding is not possible, and the production cost of the glue binding process is relatively high. In addition, the spine of glue-bound books and periodicals is thicker, and the hot melt glue used to stick the book has a higher hardness after cooling and solidifying. Therefore, the pages close to the spine of glue-bound books and periodicals are difficult to flatten when flipping through, which affects the reader's perception.

[0005] The utility model patent with application number 2023205655339 records "a folding and gluing machine", which can use a single sheet of paper to seal and glue the back to produce folded and glued books and periodicals, thereby avoiding the defects of the above-mentioned saddle stitching process and glue binding process. However, because the main body of the folding and gluing machine has a maximum limit on the paper feed size, the general maximum paper feed width is 780mm. Considering the printing size limit of the printing press and the size format of conventional paper in the industry, the folding and gluing machine can only be used to seal and produce folded and glued books and periodicals with a small number of pages or a smaller size. The content of the background technology section is only the technology known to the inventor and does not necessarily represent the prior art in this field. Summary of the invention

[0067] Figure 2 A schematic diagram showing a signature according to an embodiment of the present invention is shown, Figure 3 Shows the production Figure 2 The schematic diagram of the paper of the book signature shown is as follows: Figure 2 and Figure 3 As shown, the signature 110 may be a folded and pasted signature, and the folded and pasted signature may be a Figure 3 The paper shown is used as the basis, and is folded and pasted by a folding and pasting machine (such as the folding and pasting machine described in the utility model patent application number 2023205655339). In some embodiments, the signature 110 can also be a single-page signature formed by folding a single sheet of paper in half.

[0068] According to one embodiment of the present invention, a book 100 formed by bonding a plurality of folding pages and backing sheets satisfies the following relationship:

[0069]

[0070] Wherein: H is the height of the book spine; L is the printing length of the folded book with glued backing when it is unfolded into a flat printing surface (single sheet) and enters the printing press (i.e., the distance between the bite edge and the trailing edge of the printing surface); a is the size of the bite edge reserved for the flat printing surface; b is the size of the trailing edge reserved for the flat printing surface; c is the distance between the pages of the book signature 110 reserved for the flat printing surface imposition in the direction of the book spine height H (parallel to the direction of the bite edge or the trailing edge); is the round-up symbol; P is the number of pages, and the value of P is greater than 8 and is an integer multiple of 4.

[0071] In process practice, considering actual production constraints, a+b=22 mm and c=14 mm can generally be set; considering the format size of conventional paper in the industry and the printing limit size of the printing press, L can be 596 mm.

[0072] Compared with the prior art, the embodiment of the present invention provides a book 100 in which a plurality of book signatures 110 are stacked in the form of a nest of signatures, and the spines of adjacent book signatures 110 are glued together, so that the book 100 can be flattened for easy reading by readers.

[0073] Figure 4 A schematic diagram of a book packaging line 200 according to an embodiment of the present invention is shown below. Figure 4 Describe in detail.

[0074] The book packaging line 200 is suitable for packaging books 100, such as Figure 4 As shown, the book and periodical packaging line 200 includes a slapping unit 210, an adhesive adding device 220, a conveying device 230 and a spine pressing device 240. There are multiple slapping units 210, which are arranged at intervals along the first direction. Books can be stored in the slapping units 210. The slapping units 210 are provided with a book outlet, and a book pick-up and delivery mechanism is provided below the book outlet. The slapping unit 210 is configured to release the book from the book outlet. Specifically, the book pick-up and delivery mechanism picks up (or sucks) the book one by one from the book outlet and delivers the book 110 to the conveying device 230. The conveying device 230 is arranged below the multiple slapping units 210, especially directly below the book delivered by the book pick-up and delivery mechanism. The conveying device 230 is configured to sequentially receive the book provided by the multiple slapping units 210 along the first direction, and make the multiple book sets form a book blank. The glue adding device 220 is provided as one or more, and the number of the glue adding devices 220 can be determined according to the number of the plying units 210. The glue adding device 220 is provided between adjacent plying units 210, and the glue adding device 220 is also located directly above the conveying device 230 (especially directly above the conveying path of the book sheet conveyed by the conveying device 230). The glue adding device 220 is configured to add glue to the outer spine of the book sheet. For example, in the process that the conveying device 230 receives a book sheet from a plying unit 210 (or after receiving the book sheet), the glue adding device 220 located downstream of the plying unit 210 adds glue to the outer side of the spine of the corresponding book sheet. The spine pressing device 240 is provided downstream of the conveying device 230, and the spine pressing device 240 is configured to receive the book sheet output by the conveying device 230 and press the spine of the book sheet. When using the book packaging line 200 to package books and periodicals, the stacking unit 210, the glue adding device 220 and the conveying device 230 cooperate with each other to stack multiple book signatures in sequence to form a book blank, and add glue between the spines of adjacent book signatures. Then, the spine pressing device 240 presses the spine of the book blank to make the adjacent book signatures in the book blank stick together.

[0075] According to one embodiment of the present invention, Figure 4As shown, the conveying device 230 includes a conveying chain 231 and a driving mechanism 232, wherein the conveying chain 231 is a closed ring, and the conveying chain 231 is suitable for supporting the book signature at the inner spine of the book signature.

The first top surface 2312 and the second top surface 2313 are at a preset angle (for example, 60 degrees) to form a pointed top. After the mounting unit 210 releases the book, the book can ride on the top of the link 2311, and the pointed top of the link 2311 supports the book at the inner spine of the book.

[0076] According to one embodiment of the present invention, the driving mechanism 232 may include a motor and multiple sprockets, wherein the multiple sprockets may respectively engage with hinges or links in the conveyor chain and provide support for the conveyor chain, and one of the sprockets may be connected to the motor and driven by the motor.

[0077] According to one embodiment of the present invention, Figure 4 As shown, a triangular bar 250 is provided under each of the stacking units 210. The triangular bar 250 is suitable for supporting the signature at the inner spine of the signature. When the stacking unit 210 releases the signature through the signature picking and delivering mechanism, the signature falls and rides on the triangular bar 250. The triangular bar 250 supports the signature at the inner spine of the signature. Figure 6 Schematic diagram of a tripod 250 and a conveyor chain 231 according to an embodiment of the present invention is shown. Figure 6 As shown, the tripod 250 is located directly above the conveyor chain 231, and there is a preset interval between the tripod 250 and the conveyor chain 231. The tripod 250 is roughly triangular, and a groove is provided at the bottom. Figure 4 and Figure 6 As shown, a plurality of push rods 233 are arranged at intervals on the conveying chain 231. Preferably, the push rods 233 are connected to both sides of the chain link 2311 ( Figure 6 The push rod 233 can rotate with the conveying chain 231. When the push rod 233 passes under the attaching triangle rod 250, the push rod 233 can push the signature on the attaching triangle rod 250 and deliver the signature to the conveying chain 231. In this process, the push rod 233 also plays a positioning role, so that the signature on the attaching triangle rod 250 is aligned with the signature on the conveying chain 231 to ensure the accuracy of the attachment.

[0078] According to one embodiment of the present invention, Figure 4 As shown, the glue adding device 220 includes a sensor 221 and a glue injector 222, wherein the sensor 221 may be a photoelectric sensor (e.g., a photoelectric proximity switch), etc. The sensor 221 is disposed on one side of the conveying chain 231, and is used to detect whether a book has passed through the conveying path of the conveying chain 231, and the sensor 221 is configured to send a trigger signal in response to the passing of the book. The glue injector 222 is disposed directly above the conveying device 230, preferably, the glue injector 222 is disposed directly above the bridging triangle 250, and the glue injector 222 is electrically connected to the sensor 221, and the glue injector 222 is configured to add glue to the outer spine of the book according to the trigger signal.

The triangular pressing plate 242 is arranged just above the triangular base 241, and the triangular pressing plate 242 is configured to be switchable between a first position and a second position, wherein the second position is higher than the first position, and when the triangular pressing plate 242 is in the first position, the triangular pressing plate 242 can press the spine of the book blank against the triangular base 241, so that adjacent book signatures in the book blank are firmly adhered; when the triangular pressing plate 242 is in the second position, the book blank can pass between the triangular pressing plate 242 and the triangular base 241.

[0080] Figure 7 FIG. 2 shows a schematic diagram of a triangular base 241 and a triangular pressure plate 242 according to an embodiment of the present invention. Figure 7 As shown, the triangular base 241 includes a first supporting surface 2411 and a second supporting surface 2412, which intersect and are used to support the book blank at the inner spine of the book blank, and a first angle is formed between the first supporting surface 2411 and the second supporting surface 2412. The triangular pressing plate 242 includes a first pressing surface 2421 and a second pressing surface 2422, which intersect and are used to press the book blank at the outer spine of the book blank, and a second angle is formed between the first pressing surface 2421 and the second pressing surface 2422. Since the books and periodicals themselves have a certain thickness, in order to ensure that the triangular pressing plate 242 and the triangular base 241 can flexibly press the book blank and are not stuck, the second angle can be set to be greater than the first angle. Preferably, the second angle is 3-5° greater than the first angle.

[0081] According to one embodiment of the present invention, Figure 7As shown, the top of the triangular base 241 is configured as a rounded corner (i.e., the first supporting surface 2411 and the second supporting surface 2412 are rounded to prevent the inner spine of the book blank from being crushed by the top of the triangular base 241 when the triangular pressing plate 242 and the triangular base 241 cooperate to squeeze the book blank. Preferably, the radius of the rounded corner is 0.5-1 mm.

[0082] According to one embodiment of the present invention, Figure 7 As shown, the spine pressing device 240 also includes a first supporting member 243, and the triangular base 241 is detachably connected to the first supporting member 243 (for example, bolted, snap-fitted, etc.), so that triangular bases 241 of different specifications can be replaced according to books and periodicals of different specifications. Specifically, a connecting portion 2413 is integrally provided at the bottom of the triangular base 241, and a plurality of through holes are provided on the connecting portion 2413, and a plurality of threaded holes are provided on the first supporting member 243, and the connecting portion 2413 is connected to the first supporting member 243 by bolts.

[0083] According to one embodiment of the present invention, Figure 7 As shown, the triangular base 241 may be a metal piece with a smooth surface, so as to facilitate moving the book blank on the triangular base 241 .
