ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a pasting and bookbinding method and a pasting and bookbinding apparatus by which the paste is linearly pasted in the vicinity of the sheet side edge to image formation processed sheets, and one side edge of the sheet set is covered by the book cover and a booklet is produced, and particularly to a pasting and bookbinding apparatus which is connected to an image forming apparatus such as a copier, facsimile device, or printer, or which can be applied for the image forming apparatus, and to an image forming apparatus provided with the pasting and bookbinding apparatus.
Generally, a sheet on which an image is recorded by a copier, facsimile device, printer and image forming apparatus main body which is a composite machine of them, is variously processed as a post-processing, by, for example, punching, stapling, central stapling and central folding, book covering, folding, stamping, or pasting and bookbinding.
As a pasting and bookbinding apparatus, the following apparatus are used.
(1) An apparatus to jet the paste onto the sheet by using a paste jetting nozzle,
(2) an apparatus in which a paste wheel is provided to the paste container, and the paste is fitted onto the outer periphery of the rotating paste wheel, and the outer periphery of the paste wheel is brought into contact with the sheet and the contact transfer is conducted,
(3) a hot melt coating apparatus to jet a mixed body of a hot melt agent (thermal fusion agent) and a heating compression air from the nozzle, or
(4) a tape pasting apparatus to glue a tape onto which a paste having the adhesion property is previously pasted, onto one side edge of a sheet set while heating the tape.
A pasting method and apparatus disclosed in Japanese Tokkaihei-No. 7-80377, is a method and apparatus in which a high pressure air is blown upon the paste jetted from the paste jetting nozzle and the paste is formed into a thin film-like one.
A bookbinding apparatus disclosed in Japanese Tokkaisho-No. 59-500907 (corresponding to U.S. Pat. No. 4,473,425) is an apparatus in which the sheet conveyed in the first direction is deflected to the second conveyance direction perpendicular to the first conveyance direction, and after that, the paste is linearly pasted on the end portion of the running sheet, and after the sheets are stacked and aligned, the sheets are pressed, aligned and book-bound.
As a back side taping bookbinding method, methods in which a tape on which the paste having the adhesion property at the time of heating is previously pasted, is pasted while being heated, or a tape on which the paste having the adhesion property when the water is included, is previously pasted, is used, are well known. The conventional tape pasting method is disclosed in Japanese Tokkaisho No. 62-284795, U.S. Pat. No. 4,985,729, Japanese Tokkaihei No. 3-151286, or No. 6-115275.
In the conventional pasting and bookbinding apparatus, there are following problems.
(1) In the back side tape pasting system, after the tape is pasted onto the backbone of sheet set, because the tape is folded to the front book cover side and the back book cover side, when the system is made so that the tape can be highly reliably pasted corresponding to the kind of sheets, or the thickness of sheet set, the structure of the apparatus becomes complicated and large sized.
(2) In a system in which the sheet set is covered by a book cover which is integrated with the front book cover and the back book cover, and the back surface of the sheet set is adhered, the book cover length corresponding to the maximum thickness of the sheet set is necessary, and after the book cover is adhered by using a special large sized book cover, a process by which the excessive book cover portion protruded from the sheet set is cut and removed, is necessary.
(3) In a pasting and bookbinding apparatus by which the sheet set, front book cover, and back book cover are aligned at high speed and accurately, and the high quality bookbinding is conducted, the structure of the apparatus becomes complicated and large sized.
(4) For pasting and bookbinding the sheet delivered at a high speed from the image forming apparatus main body, in order to maintain the high speed productivity, the structure of the apparatus becomes complicated and large sized.
(5) It is difficult that the booklet which is made by thermally adhered by the hot melt coating apparatus is recycled as the regenerated paper.
(6) When a sheet set production mechanism by which the pasting processed sheet is conveyed, stacked, and the pasted portion between sheets is pressed and the sheet set is formed, and the cover bookbinding production mechanism by which the book cover surface side of the sheet set and the back book cover surface and the back portion are covered by the book cover and adhered, are accommodated in integrated pasting and bookbinding apparatus, the waiting time for the pasting and bookbinding process is generated, and the productivity for bookbinding producing is lowered.
SUMMARY OF THE INVENTION
The first object of the present invention is to provide a pasting and bookbinding method, a pasting and bookbinding apparatus and an image forming apparatus to solve the above problems.
The second object of the present invention is to provide a pasting and bookbinding method by which the above problems are solved and the pasting and bookbinding apparatus is improved, and the formation of the sheet set and the alignment and adherence of the front book cover and back book cover are surely attained, and the deterioration of the finishing quality of the bookbinding is prevented, and the productivity at the high speed processing is maintained, a pasting and bookbinding apparatus, and an image forming apparatus provided with the pasting and bookbinding apparatus.
The first object is solved by one of the following structures of the present invention.
(1) A pasting and bookbinding method which is characterized by being structured such that: the leading edge portion of the sheet conveyed in the first conveying path having a sheet conveying means is brought into contact with a hitting member and the sheet skew is corrected; a linear paste coating portion is formed by a paste jetting means in the vicinity of the side edge portion of the sheet conveyed in the second conveying path on which the sheet is conveyed in the direction perpendicular to the first conveying path; and a plurality of sheets after paste coating processing are stacked on a sheet stacking table provided below the second conveying path, and aligned by an aligning means, and the linear pasted portion is pressed by a pressing means, and after a pasted booklet is produced, the booklet is delivered by a delivery means, and delivered onto the delivery tray provided in the conveying direction downstream of the first conveying path and on an outside side surface of the apparatus.
(2) A pasting and bookbinding apparatus which comprises: the first conveying path for positioning the sheet by correcting the sheet skew when the sheet conveyed from the outside is conveyed and the leading edge portion of the sheet is brought into contact with the contact member; the second conveying path to convey the sheet in the direction perpendicular to the first conveying path; a paste jetting means which is provided on the second conveying path and to form a paste coating portion in the vicinity of the side edge portion of the sheet; the third conveying path to reversed-convey the sheet after the paste coating processed; the fourth conveying path to stack the sheets onto the sheet stacking table provided below the second conveying path; an alignment means for aligning a plurality of sheets stacked onto sheet stacking table; a pressure means for pressing the pasted portion and producing the booklet; a delivery means for delivering the booklet; and a delivery tray which is provided on the conveying direction downstream of the first conveying path and an outside side surface of the apparatus, and which accommodates the delivered booklet.
