Field of the Invention The present invention relates to a cover material for covering a core material with a cover material in a process of manufacturing a thick cover member of a book called a hard cover. The present invention relates to an apparatus for folding and bonding the four corners. 2. Description of the Related Art In general, a book cover is roughly classified into a thick cover sheet and a thin cover sheet. Among them, a thick cover member called a so-called hard cover is manufactured as follows. That is, a core material for a front cover, a core material for a back cover, and a core material for a back cover made of paperboard or the like are placed and adhered at predetermined positions on the back surface of a cover material made of paper, cloth, or the like to which adhesive has been applied in advance. . Next, the periphery of the facing material is folded back so as to wrap these core materials, and is bonded while being careful not to cause air bubbles between the facing material and the core material.
In this way, the cover member is completed. [0003] Among these steps, there are conventionally two methods for folding the periphery of the surface material so as to wrap the core material. The first method is a method in which four corners of the facing material are cut off obliquely in advance, a core material is stuck to the facing material, the top and bottom portions, and the edge of the facing material are folded back and overlap in the order of the fore edge portion and bonded. (FIG. 7A). The second method is a method in which, while the surface material remains rectangular, first, the four corners are folded back and adhered in a triangular shape, and then, in the same manner as described above, the top and bottom, and the front edge are folded back and adhered (FIG. 7B )). In the step of folding and bonding the peripheral edge of the facing material, the work requires a technique, and thus, in the past, it has been necessary to rely on manual work by skilled workers. Mechanization has been promoted, for example, by mechanically mechanizing or connecting those processes by a conveyor.
For example, Japanese Patent Publication No. 3-17677, Japanese Patent Publication No. 3-5159
No. 9 and JP-A-1-316291 disclose techniques for more reliably turning up and down the fore-edge portion of the surface material. [0005] However, all of these techniques are based on the theme that the top and bottom and the fore-edge portion are folded back by using a facing material in which all sides are cut in advance. No mention is made of a technique for folding back the corners of the triangular shape in advance into a triangular shape. Also, at present, there is no mechanical device that is designed to fold the four-sided corners of the facing material in advance. [0006] In view of such circumstances,
SUMMARY OF THE INVENTION The present invention proposes an apparatus for reliably folding and bonding the four corners in advance when manufacturing a thick cover member using a rectangular covering material in which the four corners are not notched. [0007] In order to solve the above-mentioned problems, the present invention provides a folding adhesive device for a corner portion of a thick cover, which is supported on guide rods (4) provided on both sides of a base (1). A belt conveyor (2) is slidably supported via an arm (3), and the belt conveyor (2) is moved back and forth by a cylinder (5) via a connecting rod (6) attached to the support arm (3). A base plate (8) that can be raised and lowered by a cylinder (7) is provided before and after the base (1), and both ends of the upper surface of each base plate are angled toward the inside at 45 degrees. A corner folding unit (9) is provided. The corner folding unit (9) is provided with a table part (13) slidable forward and backward on a base part (12), and a folding base (14) is fixed on the upper surface thereof. , Right side triangular recess (17) on the back
A folded plate (16) provided with is provided above the folded base,
The folded plate can be moved up and down by a cylinder (15). In the apparatus according to the present invention, the cover member (a) placed on the belt conveyor (2) is first moved forward, and a pair of front corner folding units (9) is moved. Then, the front corner of the cover member is folded back, and then the cover member is retracted, and the rear corner of the cover member is folded back by a pair of rear corner folding units (9). In the corner turning unit (9), first, the entire corner turning unit is raised, the corners of the facing material are bent upward by the turning plate (16), and then the table (13) is advanced inward. ,
While turning the corners, the folded base (14) and the folded plate (1)
6), the folded plate (16) is further lowered, and the corners are pressed to securely adhere the surface material. At this time, the cover core of the cover member is fitted into the concave portion (17) provided on the back surface of the folded plate (16), and the corners are more completely bonded. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the apparatus according to the present invention will be described below with reference to the drawings. In FIGS. 1 to 3, (1) is a base of the present apparatus, and (2) is a base of the base (1). It is a belt conveyor attached above via a support arm (3). The support arm (3) is slidably supported by guide rods (4) mounted on both sides of the base (1), and is connected to the belt conveyor by a cylinder (5) and a connecting rod (6) mounted on the side of the base. (2) It is possible to move itself back and forth. In addition, a base plate (8) which can be raised and lowered by a cylinder (7) is provided before and after the base (1). A unit (9) is provided. One of the corner turning units (9) is slidably attached to the guide rod (10), and can be fixed or moved with, for example, a set screw (11) or the like, so that the interval between the turning units can be adjusted. Thus, it is possible to cope with the covers of books of various sizes. Each corner turning unit (9)
As shown in FIG. 4, a table (1) slidable back and forth by a cylinder (not shown) built in the base (12).
3) and a folded pedestal (1) fixed to the upper surface of the table section.
4) and a folded plate (16) that can be moved up and down by a cylinder (15). The folded plate (16) is located above the folded pedestal (14) and has a back surface and a cover member described below with the pedestal. (B) is pinched and pressed. A right-angled triangular recess (17) corresponding to the corner of the cover core material is provided on the back surface of the folded plate (16). Next, a method of folding back a corner portion of a thick cover member using the present apparatus will be described with reference to FIG. 5. First, in a previous step, a core material for a cover cover is attached to the back surface of a cover material coated with an adhesive in advance. The core material for the back cover and the core material for the spine are placed and adhered to predetermined positions, respectively. The cover member (a) is placed at an appropriate position on the belt conveyor (2) of the present apparatus by an arbitrary method, and the folding process is started. First, the belt conveyor (2) is rotated forward, and when the front end of the cover member (a) jumps out of the front end of the conveyor and comes to an optimum position above a pair of front corner folding units (9), the conveyor is rotated. Is stopped (FIG. 5). At this time, the cover member is fixed by a known fixing device (not shown) such as pressing from above so that the cover member does not displace. Next, the cylinder (7) provided below the front base plate (8) is operated to raise the pair of corner turning units (9) together with the base plate. As a result, both front corners of the cover member (a) come into contact with the upper surface of the folding plate (16) and are bent upward (FIG. 5). When the lower surface of the cover member comes into contact with the folding pedestal (14), the lifting of the base plate is stopped. Next, when the table portion (13) is advanced, the corners of the cover member are bent inward and enter the gap between the folding pedestal (14) and the back surface of the folding plate (16) (FIG. 5). When the folded plate cylinder (15) is operated to lower the folded plate (16), the corners are pinched and pressed between the folded pedestal and the back surface of the folded plate, so that the folded facing material and the core material are bonded. Then, the folding of the corner of the cover member is completed (FIG. 5). In this case, a right-angled triangular recess (17) corresponding to the corner of the cover core material is formed on the back surface of the folded plate (16).
Is provided, the corners of the cover core material are fitted into the recesses, and as shown in FIG. 6 (B), the cover materials that do not overlap with the core material are also polymerized and adhered to each other to reliably turn the corner portions. be able to. When the turning of the front end is completed, the cylinder (15) is operated again to raise the turning plate (16) to open the corner (FIG. 5). At the same time, the cover member fixing device is also released. Next, the belt conveyor (2) is rotated backward and the cover member is transferred in the opposite direction, and at the same time, the table portion (1) of the corner turning unit is rotated.
3) is also retracted and returned to the original position (FIG. 5). Thereafter, the cylinder (7) of the base plate is operated to lower the corner turning unit together with the base plate and return to the original position (FIG. 5).
,). When the corner turning unit (9) descends to its original position, the cylinder (5) attached to the base (1) is actuated to pull the entire belt conveyor via the connecting rod (6), and a pair of the front parts is used. Corner turning unit (9)
Move it up. Next, the belt conveyor (2) is rotated backward, and the rear end of the cover member jumps out of the rear end of the conveyor and reaches the optimum position above a pair of rear corner folding units (9). Is stopped, and is further fixed by the cover member fixing device. In this state, the rear corner turning unit is raised, moved forward and lowered in the same manner as described above, and the rear corner of the cover member is turned back and adhered. This completes the folding of the four corners of the cover member. When the folding of the rear end is completed, the fixing device of the cover member is released, and the belt conveyor (2) is rotated forward, and the completed cover member is subjected to the next step, for example, to the edge of the cover material at the top and bottom. Transfer to the return process. At this time,
The rear cylinder (15) is activated, and the rear corner turning unit returns to its original position. Further, the cylinder (5) is operated, and the belt conveyor (2) returns to the initial position, so that the next cover member can be turned back. In the above process, the optimum position of the cover member is determined by the rotation of the belt conveyor, for example, by detecting the cover position with an optical sensor or the like and controlling the belt conveyor. Each cylinder is driven by a known method such as pneumatic pressure or hydraulic pressure, and the driving is controlled by a known control device together with the timing of the entire series of operations. According to the apparatus of the present invention, the four corners of the surface material, which have conventionally depended on the manual work of a craftsman, can be easily and reliably folded. Therefore, the step of notching the corners of the surface material in advance is not required, and the overall work efficiency is improved. In addition, since the cover material is superimposed on the corner portion by folding, a robust cover member can be manufactured. In addition, since the concave portion is provided on the back surface of the folded plate, the corner portion is securely bonded, and when the back and forth portion and the fore edge portion are bonded in the next step, it can be performed smoothly and beautifully. And various other excellent effects.
