DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bookbinding apparatus for binding an image-formed sheet to a book, and more particularly to, for example, a plurality of apparatuses necessary for continuously forming an image and a sheet formed with the image. The present invention relates to a bookbinding apparatus that is applied to an online apparatus that is connected to a bookbinding apparatus that binds a book, and a sorting storage device that sorts and sorts the finished bookbinding product.

[0002]

2. Description of the Related Art Conventionally, when a plurality of sheets on which an image is formed are glued together and automatically performed continuously, an online apparatus in which a plurality of apparatuses for performing necessary jobs are connected is used. I have.

For example, the above-mentioned online apparatus includes a document setting unit for setting a document, an optical system for scanning the document, and a paper feed unit for storing and feeding a large number of sheets. A paper device, an image forming apparatus that forms a surface image of a fed sheet, a bookbinding apparatus that binds an image-formed sheet, a sorting storage device that sorts and stores a bound finished product or a single sheet, and the like are sequentially connected. Made of things.

[0004] When bookbinding is performed in a bookbinding apparatus, there is a glue binder that glues and binds the aligned sheet bundle in the sheet alignment tray. The bind tape used for this is a type formed by applying hot-melt glue to a tape-like sheet, and is heated and melted by a heater and brought into contact with the sheet bundle to glue the sheet bundle.

Further, the sheets are stored in one alignment tray, and the sheets are aligned by bringing the sheets into contact with the abutting members.
Then, the sheet bundle and the bind tape in contact with the sheet bundle have been heated by one tape heating unit.

[0006]

However, in the above-described conventional bookbinding apparatus, it takes time from setting the bind tape to the tape heating means to melting it.
Further, even when the melted bind tape was brought into contact with the sheet bundle and heated, the heat was taken away by the sheet bundle and sufficient bonding could not be performed. That is, it takes a long time to heat the sheet bundle at room temperature to the gluing temperature.

Further, since an image forming apparatus which forms an image at high speed and with a short sheet interval is applied to the image forming apparatus, if only one sheet aligning tray is used, it takes a long time to align the sheets. Since the sheets are continuously supplied, the productivity of the apparatus is reduced, and when the time required for heating the sheet bundle is added to the above, the productivity is further reduced.

Further, providing two alignment trays occupies a space and increases costs.

In a conventional image forming apparatus and an on-line bookbinding apparatus, a sheet bundle aligning means, a conveying means, and a stacker are arranged in series from a sheet carry-in port , and the conveying means is of a handling type. According to this method, in the bookbinding operation, the single sheets sequentially fed in from the carry-in entrance are aligned in a sheet bundle by the aligning means, and then the bind tape is bound by heating with a heater, and the finished bound product is sent to the stacker to be stacked. It has become. When the specified number of books are completed or the stacker is full, the stacker is unloaded, the tray of the stacker protrudes outside the machine, the operator removes the book, and the tray is automatically stored inside the machine. , And then go back to standby. At this time, the apparatus stops the bookbinding operation until unloading from the unloading is completed and the apparatus enters the standby state again, and the productivity is reduced.

In addition, simple bookbinding such as a stapler or a folder, which is a finishing device provided upstream of the bookbinding device, similarly stops, and the operating rate of the machine decreases.

On the other hand, the sheets on which images have been formed are stacked on a stacker or a paper discharge tray, but the operator must manually sort them. However, in order to minimize these efforts, there has recently been an increasing demand for sorting devices such as sorters, mailboxes and multi-client sorters.

However, in the bookbinding apparatus having the above-described modules arranged in series, the productivity changes depending on the bookbinding work time because the transporting means operates in series with the bookbinding work. It is not preferable that the productivity of the entire apparatus is reduced by the bookbinding apparatus which takes the longest tact time in an online image forming apparatus, even from the viewpoint of cost and productivity of a high-speed image forming apparatus.

Further, in the online system, the image forming means and other finisher petri upstream from the bookbinding apparatus, when placing the sorting device on the downstream side of the bookbinding apparatus, the sorting apparatus, a single sheet, the staple bundle sheet, simple made genuine stapled sheet bundle that is not based on bar-in Dotepu method such fold bundle sheets will have to pass through the conveying section in the bookbinding apparatus. In the conventional serial type bookbinding apparatus, the final process is a stacker, so that the bookbinding apparatus and the booklet created by another finisher are mixed in the same stacker, or the job is separated from each other. I had no choice but to make it work. For this reason, the sorting device cannot be provided downstream.

Further, in a device in which a sheet bundle whose leading end is aligned by an abutting member in an alignment tray is moved straight to a back contact position, and the back and side are heated and bound by a tape heating device and a side heater, It is desirable to set the distance between the abutting member and the tape heating device so that the heating operation of the tape heating device and the side heater can be performed.

[0015]

According to the present invention, the distance between the abutting member for aligning the sheet bundle in the alignment tray and the tape heating binding means for heating and binding the binding tape to the sheet bundle is set longer than the sheet bundle, and the tape heating binding is performed. It is an object of the present invention to provide a bookbinding apparatus in which the operation of the means is smooth.

[0017]

SUMMARY OF THE INVENTION A bookbinding apparatus according to the present invention has an alignment tray for aligning a sheet conveyed in a sheet conveying path, a position for aligning the leading end of the sheet in the alignment tray, and an evacuation from the alignment position. An abutment member that can temporarily move a position and temporarily stores a sheet in the alignment tray;
