Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a bookbinding device that stacks copies ejected from a copying machine and binds them with a stable.

Prior Art When a set of original documents consisting of multiple sheets is copied using a copying machine,
Conventionally, staplers (trade name: Stapler) are used to manually staple one corner or 2.6 points on the - side.

Recently, a recycled automatic document feeder δ (RADF) has been used as part of office automation, but in this case, a set of documents is automatically fed onto the contact glass of the Q4 machine and fed once. One exposure is performed for a fed sheet of paper, the original is fed by circulating it a predetermined number of times, and a series of copies are continuously ejected from the copying machine in a predetermined number. Therefore, if a simple bookbinding machine that can automatically staple each set of consecutively output copies is connected to the copy output port of a copying machine, the bookbinding work can be done without manpower. First, the bookbinding work is speeded up, which is convenient.

As a bookbinding apparatus for this purpose, for example, a document copying apparatus with a copy finishing device is disclosed in Japanese Patent Application Laid-Open No. 53-119.047. In this device, copies ejected from a copying machine are ejected onto an artistically inclined tray, and the tip of the tray is pressed against a stopper whose position can be changed according to the copy size and which can be retracted from the surface of the tray. Then, one side edge is pressed with a push-butting device so that it abuts against the side guide whose position has been adjusted in advance according to the copy size, and the stack is stacked.The rear edge of the stacked group of copies in the conveying direction is fixed at two places with a stapler. After binding, the stopper is retracted below the surface of the tray, and the bound copies are slid down and received by the copy receiver.

Now, when binding a copy made from an original using a copying machine, it is often desirable to bind the book with a cover or a cover and a back cover. However, in the copy finishing device attached to the above-mentioned document copying device, only the copies ejected from the copying device main body are ejected to the finishing tray, so copies other than originals are sent to the finishing tray. Not introduced, with front and back covers attached. If necessary, blank sheets must be stacked on top and bottom of the stack of originals and placed on the paper feed tray of the original feeder, and the blank sheets must be copied before and after copying the original original.

It is desirable to use thicker paper for the front and back covers than the copy paper inside, but with the above method,
The paper quality and thickness of the back cover are not appropriate because the paper is the same as the transfer paper used to copy the original manuscript. Moreover, it is a waste of time to go through the same process as for copying images in order to supply front and back covers that do not require copying images.

Furthermore, if the bookbinding machine can be used as a stand-alone bookbinding machine for binding printed papers, etc., unrelated to the copying machine, in addition to binding lobby books discharged from the copying machine, the utility of the bookbinding machine will be further increased.

Purpose The present invention eliminates the above-mentioned drawbacks of conventional bookbinding machines attached to copying machines, and makes it possible to use paper of appropriate paper quality and paper thickness for the front and back covers, which is different from general transfer paper. I can do it,
It does not require unnecessary processes or time to feed the paper for the cover to the bookbinding machine, and in addition, it can be used as a standalone bookbinding machine. The purpose is to provide bookbinding machines.

Configuration The above object is, according to the present invention, to provide a receiving means for receiving copies ejected from a copying machine and conveying them forward, and a receiving means for receiving copies ejected from a copying machine from the bottom to the top in the order in which the copies received from the copying machine are received through the receiving means. an intermediate stacking means for stacking one another; a means for conveying a group of copies stacked on the intermediate stacking means to a finishing section by turning them upside down;
This is achieved by providing a portion of a feeder capable of supplying sheets other than copies ejected from a copying machine to the above-mentioned receiving means of a bookbinding apparatus that is equipped with finishing means for performing finishing operations such as stapling and punching.

It consists of a driving device.

The operation of the bookbinding apparatus configured as above will be explained below.

Before explaining the detailed operation, an outline of the overall operation will be described.

The bookbinding device 2 starts operating LfFJ when the document start button of the document supply device attached to the copying machine 1 is pressed. When a front cover and a back cover are attached to a copy, the cover is first sent from the feeder section B to the intermediate tray 100 of the intermediate stacking section C via the receiving rollers 14,15. Next, the copies from the copying machine 1 are fed into the intermediate stacking section C via the copy receiving section A in page order with the image 1m facing downward, and stacked on top of the previously fed cover.

When a predetermined number of copies have been fed, the back cover is fed again from the feeder part B and is stacked on top of the copy stack. There, a series of copies (hereinafter referred to as a group of copies) aligned with the front and back covers is guided by a U-shaped guide plate, makes a U-turn, is turned upside down, and is sent to a finishing section where it is placed in a designated position. Finishing work (stable, punch) will be carried out. By doing this, the image side will face up,
A stable is driven from above into a group of copies consisting of copies arranged in page order from top to bottom, front and back covers stacked above and below, and finishing can be achieved by punching from above. The group of finished copies is discharged onto the paper discharge tray 66 and stacked.

Next, the functions of each part will be explained.

Paper feeding roller 5 of feeder part B, double feeding separation means 6.7,
8. The function of the pinch roller pair 10.11 is the same as that of the transfer paper feeding section of a general copying machine, but relatively thick paper is used for the front and back covers, so thick paper is used. It has a performance that ensures that sheets of paper are fed one by one. In addition, when using this bookbinding machine 2 alone to bind printed sheets other than copies ejected from the copying machine, a booklet with aligned pages is placed on the paper feed tray 4 of the feeder part B.
A set of sheets, etc. is placed and sent to the finishing section via the intermediate stacking section C using the above-mentioned members in order for finishing.

The peripheral speed of the pair of receiving rollers i4, 15 in the copy receiving section A is the same as or several times faster than the transport speed of the copying machine 1. Rotation starts based on the signal detected.

The sheets discharged onto the intermediate tray 100 are guided by the presser plate 20, and even sheets with face curls are reliably aligned on the intermediate tray. It makes a reciprocating movement once every time a sheet is delivered,
The front and rear positions of the paper are aligned. Both sides of the paper are also aligned in a predetermined position by a similar device (not shown).

When it is confirmed that the final sheet of the set (last page copy or back cover When the sensor 54 confirms that the group of copies has been fed out, the feed roller 50 provided at the tip of an arm 61 that swings about a shaft 60 moves the group of copies to the left by the action of a solenoid. The upper surface of the group of copies (the back side of the copies) is pressed and the group of copies is turned in a U-turn along guides 22 and 23, and the copies are sent toward the finishing section tray 101 with their image surfaces facing upward.

When the leading edge of the group of copies is detected by the sensor 55, the receiving roller 24 presses the group of copies by the action of a solenoid, and the leading edge is inserted into the recessed part 30a of the finishing machine 30 along the guide 29 at the speed of the guide belt 27. aligned and positioned. A group of copies follows a preset mode, those in stable mode are stabilized in a predetermined position,
Furthermore, the object to be punched is punched in a predetermined position. After stabilizing and punching, the first group of copies
As shown in the figure, an arm 111 that swings around a shaft 110 under the action of a solenoid pushes back the tips of the group of copies to a position where they are removed from the recess 30a of the finishing device 30.
Next, the tray 101 is rotated together with the guide belt 27 to an inclined position shown by the chain line in FIG. It is sent out onto the tray 63.

A height detection feeler 34 is provided above the paper output tray 36, and is always in contact with the top surface of the group of copies fed into the paper output tray 63, and detects the height of the top surface of the group of copies.
The height of the top surface of the group of copies stacked on the paper output tray 36 is not much different from the front end of the tray 101, which is always inclined! The height adjustment link mechanism 65 adjusts the height to a constant height. Note that the paper ejection tray 63 is connected to the link mechanism 3.
