DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing a book 1 according to this embodiment. Book 1 has a main body 10 including a plurality of pages on which text, images, etc. are printed, a front cover 21 and a back cover 22 arranged to sandwich main body 10, and a string-like spine 6. Main body 10 has a plurality of quires, each having a plurality of pages, and front and back endpapers arranged to sandwich the plurality of quires. Front cover 21 and back cover 22 are joined to the front and back endpapers, respectively. In this invention, the term "book" is a concept based on structure, and includes what are commonly called "notebooks (schedule books)" and "diaries," etc. In such cases, only ruled lines may be printed on the main body.

[0011] The spine 6 is attached to the spine of the main body 10 with an adhesive or the like. Furthermore, the end of the spine 6 attached to the spine is covered with the label 7. The label 7 has a portion that covers the end of the spine 6 attached to the spine, and both ends of the label 7 are folded and attached to the front cover 21 and the back cover 22. In this way, the end of the spine 6 is fixed to the spine of the main body 10 so that it does not easily come off from the main body 10. In the present invention, the label 7 need only cover a certain area of ​​the end of the spine 6 (a position closer to the fixed end than the midpoint of the spine in the longitudinal direction), and does not have to cover the end completely. Therefore, one end of the spine 6 may be exposed and not covered by the label 7.

[0012] An example of a method for manufacturing the book 1 according to this embodiment will be described. First, the main body 10 is fabricated using a known procedure. An example of the procedure is as follows. A number of folded sections are stacked, and the endpapers, folded in half, are placed between the folded sections. The front and back endpapers are then pasted with a cover 21 and a back cover 22, respectively. The book is then bound. Various well-known binding methods, such as sewn binding, thread binding, and perfect binding, can be used for the binding. There are no limitations on the manner in which the front cover 21 and back cover 22 are joined to the inside paper, and they may be joined together entirely or only partially.

[0013] Next, the signature is cut on three sides except for the spine, separated into individual pages, and the spine 6 is attached. There are no particular restrictions on the method of attaching the spine 6, and various adhesives such as cold glue and emulsion bond can be used. It is preferable to sandwich the attached spine inside the main body 10 so that it does not interfere with subsequent processes. The steps up to this point can be performed using a known binding machine equipped with a spine attachment function. There are various types of binding machines, such as a "vertical type" in which the spine 6 is attached while the book body 10 is conveyed with the cover 21 and back cover 22 in a nearly vertical position and the spine facing up, and a "diagonal type" in which the spine 6 is attached while the book body 10 is conveyed with the cover 21 or back cover 22 in contact with an inclined conveying surface, but there are no limitations and any type may be used.

[0014] As a result of the above, a pre-printed book is completed with the spine 6 attached to the main body 10. Next, a label 7 is attached to this pre-printed book using a spine fixing device.

[0015] The spin fixing device according to this embodiment includes a label attaching section, a stacking section, and a pressing section. Pre-printed books are sequentially passed through these sections by a conveyor or other transport mechanism, and labels 7 are attached to the pre-printed books to form the books 1.

[0016] FIG. 2 shows the label attachment section 110 of the spin fixing device 100 according to this embodiment. The labeling unit 110 includes a camera 111, a labeler 121, and a pair of rollers (pressing members) 131.

[0017] The camera 111 captures an image of the pre-printed book heading towards the labeler 121 and acquires an image to be used for defect determination, which will be described later. The labeler 121 has a first reel 122 that supplies labels 7, a second reel 123 that takes up the remaining separator, and a plate 124 for feeding out the labels. As shown in Fig. 3, a plurality of labels are arranged on a long separator S in the longitudinal direction of the separator. As shown in Fig. 3, the pair of rollers 131 are arranged with their rotation axes substantially perpendicular to the conveying direction (indicated by arrow D in Fig. 3) and spaced apart so that pre-printed books can pass through. Of course, the rollers 131 may be configured so that the space between them can be adjusted according to the thickness of the pre-printed books to be supplied. The camera 111 and the labeler 121 are connected to a control unit (not shown) that controls the operation of the labeler. The control unit can be configured by combining software with a personal computer or dedicated hardware.

[0018] The operation of the label attachment unit 110 in the spin fixing device 100 will be described. A user supplies pre-printed books to the upstream side of the labeling unit 110. The supply may be done manually or automatically using a feeder or the like.

[0019] The pre-book being conveyed is photographed by the camera 111 before reaching the labeler 121, and the obtained image is sent to the control unit. The control unit determines whether the spine is properly attached to the pre-printed book by performing image processing on the acquired image.

[0020] The pre-book enters the labeler 121 with a part of the upper side, to which the label 7 is to be attached, protruding from the conveying mechanism. The labeler 121 drives the second reel 123 to wind up at a predetermined timing when the pre-book approaches. Then, the separator S is wound up and moves to the opposite side of the plate 124, while the label 7 is peeled off from the separator S without following the separator S. As a result, as shown in FIG. 4, the label 7 is fed downstream of the pre-book 1p, i.e., forward in the conveyance direction, with the adhesive surface facing the pre-book 1p, with a portion of the label 7 supported by the separator S. When the pre-printed book 1p is further conveyed in this state, the label 7 is eventually attached to the spine of the pre-printed book 1p so as to cover the end of the spine 6.

[0021] The pre-book 1p to which the label 7 is attached is further conveyed and passes between a pair of rollers 131. At this time, both ends of the label 7 that are not in contact with the pre-book 1p are folded by the rollers 131 and pressed toward the front cover 21 and back cover 22 to be attached, as shown in FIG.

[0022] This completes the initial attachment of the label 7 to the pre-book 1p. In this embodiment, if the control unit determines that the spine is not properly attached to the pre-book, i.e., that the pre-book is "defective," the control unit controls the labeler 121 so that the second reel 123 does not perform winding drive. As a result, a new label is not paid out, and the pre-book determined to be defective passes through the labeler 121 without a label attached.

[0023] After the primary attachment, the pre-book is moved to a stacking section by a transport mechanism. 6 is a schematic diagram showing the accumulating section 140 and the pressing section 150. In this embodiment, the conveying mechanism leading to the accumulating section 140 is uphill, and the accumulating section 140 is located downstream of the end point of the conveying mechanism. The pressing section 150 is located directly below the accumulating section 140.

[0024] Fig. 7 is a view from the upstream side in the conveying direction of the area surrounded by the dashed line in Fig. 6. As shown in Fig. 7(a), the accumulation section 140 has a pair of guides 141 and a pair of supports 142 arranged below the guides 141. The transported pre-book 1p enters between the pair of guides 141 while being arranged by the guides 141, and is supported by the supports 142 and piled up as shown in Fig. 7(a). When a predetermined number of pre-book 1p (five in the illustrated example) are piled up, the pair of supports 142 move away from each other as shown in Fig. 7(b). As a result, the piled pre-book 1p loses support from the supports 142, falls, and moves to the pressing section 150. The timing when the support 142 moves, that is, the timing when a predetermined number of pre-printed books 1p have been piled up, can be detected by various sensors using the total weight and height of the piled up pre-printed books. There is no particular limitation on the manner in which the support can be moved. In addition to the horizontal movement shown in the figure, the support may be attached to a rotating shaft and rotated to move.

[0025] The pressing section 150 has a pair of guides (not shown) similar to the guide 141, and the pre-book 1p dropped from the stacking section 140 is arranged between the guides while being arranged by the guides. As shown in Fig. 6, the press unit 150 has a presser 151 that presses the label 7 attached to the pre-printed book 1p. The presser 151 is attached to a cylinder 152, and as shown in Fig. 8, is configured to be able to protrude and retract through a slot 153a in a plate 153 arranged opposite the spine of the pre-printed book 1p.

[0026] The plurality of pre-printed books 1p arranged in the press section 150 are stacked with the positions of the labels 7 generally aligned, and the slots 153a of the plate 153 are formed to correspond to the positions of the labels 7. In this state, when the cylinder 152 is driven and the presser 151 protrudes from the slot 153a, it comes into contact with the label attachment portion of the stacked pre-printed books 1p and presses the label 7 toward the main body 10. After the initial attachment, the label 7 located on the spine of the pre-book 1p may not be in close contact with the spine 6, as shown in FIG. 9(a). This is problematic because the spine 6 is not sufficiently fixed despite the label 7 being attached. However, even in this case, when the press unit 150 presses the floating label 7 against the main body 10 by the presser 151, and the label 7 adheres to the spine 6. As a result, as shown in FIG. 9(b), the spine 6 is sandwiched between the main body 10 and the label 7 and is sufficiently fixed, effectively preventing it from slipping off. In this state, the label 7 forms a U-shape with the boundaries between the spine and the front and back covers tightly folded.

[0027] After the pressing process in the press unit 150, the pre-book 1p becomes the book 1. The guide of the press unit 150 retracts, and the book 1 is moved by the transport mechanism to a collection location for finished products. In this embodiment, because labels are not attached to defective pre-printed books, there is a possibility that unfinished products that have not become books 1 may be included among the products transported from the press unit 150. Such unfinished products are removed by workers at the collection point.

[0028] As described above, by using the spine fixing device 100 according to this embodiment, the label 7 can be attached so as to cover the end of the spine 6 of the pre-printed book 1p after the spine is attached. As a result, even if the spine is tightly woven and adhesive does not easily penetrate, it can be reliably fixed to the main body, and the spine can be suitably prevented from falling off after completion.

[0029] Furthermore, since the label pasting unit 110 has a pair of rollers 131 and the pressing unit 150 has a presser 151, the label 7 is pressed against the spine, the front cover, and the back cover, and the spine 6 can be securely fixed.

[0030] Furthermore, in this embodiment, the labeling unit 110 has a camera 111, and the presence or absence of defects in the spine attachment state of the pre-printed book is determined before labeling based on the image captured by the camera 111. Since labels are not attached to pre-printed books determined to be defective, defective books removed by the worker can be redone by attaching the spine without removing the label. This prevents the hassle of removing the label and the waste of products due to poor appearance, and improves manufacturing efficiency without making the work excessively complicated.

[0031] As described above, the spin fixing device according to this embodiment firmly folds the label 7 into a U-shape, but if the label has high rigidity, the folded portion may return to its original shape, which may lead to lifting of the label 7 that holds down the spin 6. In the inventor's study, it was found that the label 7 substrate used in the present invention is made of a material with a basis weight of 65 g / m 2 Less than 55 g / m, more preferably 55 g / m 2 We have found that such restoration can be almost completely prevented by using the following paper. 2 Nonwoven fabrics and resin films with a similar weight per unit area can also be suitably used as the substrate. When using a resin film, there are no particular restrictions on the material, but a thickness of 150 μm or less is preferred, and a thickness of 80 μm or less is more preferred. The material of the adhesive layer provided on the substrate is not particularly limited, and for example, an acrylic adhesive or a rubber adhesive can be used.

[0032] Although one embodiment of the present invention has been described above, the specific configuration is not limited to this embodiment, and modifications and combinations of the configuration within the scope that does not depart from the gist of the present invention are also included.

[0033] For example, in the spin fixing device according to the present embodiment, a camera and a spin fixing failure determination using the image are not essential, and therefore the spin fixing device may be configured without a camera and without determining whether or not the spin fixing failure is present.

[0034] Furthermore, the stacking unit is not essential to the spin fixing device according to this embodiment. For example, the spin fixing device may be configured so that the pressed books after the primary pasting are not stacked but are transported to the pressing unit and are sequentially pressed.

[0035] Furthermore, a squeegee plate or the like may be used instead of a roller as a member for pressing the label toward the front and back covers in the label attachment section. However, if the pressing member is configured as a roller, there is an advantage in that the roller can be actively rotated to assist the transport of the pre-printed book. In such a squeegee plate or presser of the press section, the parts that come into contact with the label or pre-printed book may be made of a flexible material to prevent damage to the label or pre-printed book.

[0036] In addition, if the label substrate is highly flexible and it is expected that the label will not lift as described above, the spin fixing device can be configured without the press unit.

[0037] In the above embodiment, an example was described in which the spin fixing device was independent of the binding machine, but it may also be configured so that the binding machine is connected upstream of the spin fixing device and the produced pre-book is directly supplied to the spin fixing device. In this way, the process from attaching the spin to attaching the label can be carried out seamlessly, significantly improving the efficiency of book production.

[0038] The above embodiment is merely one aspect of the spin fixing device according to the present invention. Therefore, the posture of the pre-printed book during transport and the direction of movement when the label is attached to the pre-printed book do not need to be the same as in the above embodiment and may be changed as appropriate.
