Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a first rotating shaft to which a punch is fixed, a second rotating shaft to which a die is fixed, and a first rotating shaft. with respect to the sheet processing apparatus having a drilling equipment which are integrally formed with a drive transmission means for rotating in synchronization with the second rotary shaft. 2. Description of the Related Art An apparatus for perforating paper is disclosed in Japanese Utility Model Application Laid-Open No.
JP-A-12258, JP-A-1-193761,
For example, Japanese Patent Publication No. 2-42221 discloses a configuration in which a punching device is configured to temporarily stop a copy sheet to perform punching. [0003] Among the conventional devices,
Japanese Utility Model Application Laid-Open No. 61-12258, Japanese Patent Publication No. 2-42221
In the publication, when the copy productivity is increased, the interval between conveyed copy sheets is shortened, and a problem occurs that the punching process cannot be performed in time. Further, in Japanese Patent Application Laid-Open No. 1-193661, there is a drawback that the mechanism is complicated because an intermediate tray is provided in the middle of a transport path for performing a punching process. The present invention eliminates the disadvantages of the conventional apparatus, and detachable drilling unit in the conveying path, or without perforating apparatus, Hakare the commonality of apparatus for mounting the punching device, or
In addition, a punching device is separately provided in the middle of the transport path, so that it is possible to easily respond to the need of the punching process by the user and to make the punching device perform at a high speed. It is an object of the present invention to provide a paper processing apparatus that can be simplified. [0006] The above object is achieved by a first rotating shaft to which a punch is fixed, a second rotating shaft to which a die is fixed, and the first rotating shaft and the second rotating shaft. Uni and drive transmitting means for rotating in synchronization with the rotation shaft of integrally formed
Paper to the punching device and the processing tray for post-processing.
And a transport path for transporting the transport bus.
In place of the transport path,
The punching device is removably mounted in the
By the punching device installed in the middle of the path, the transport
A part of the path is formed, and the first rotation shaft and the second rotation shaft are conveyed between the first rotation shaft and the second rotation shaft by rotating in synchronization with each other. This is achieved by the first means for performing the perforating process while transporting the incoming paper. [0009] In the first means, since the punching device is detachable from the transport path, a common device for mounting the punching device regardless of the presence or absence of the punching device. Therefore, it is possible to easily respond to the user's request for necessity / unnecessity of perforation processing. Perforator
Is installed separately in the middle of the transport path, so
It can be performed at high speed, and the post-processing machine of the processing tray
The structure can be simplified. Hereinafter, embodiments of the present invention will be described with reference to the drawings. [0015] Figure 1 is a block diagram of a use Kamisho management apparatus according to an embodiment. In the figure, reference numeral 1 denotes a copying machine main body, and 2 denotes a post-processing apparatus main body connected to the downstream side of the copying machine main body 1. The copy paper discharged from the discharge section 11 of the copying machine main body 1 enters the post-processing apparatus main body 2 side, and is copied by the branching claws 12 to a processing tray 13 which performs post-processing such as collating, sorting, and bookbinding. And a second transport path 16 for transporting the copy paper to the collection tray 15 where the above processing is not performed. A rotary punch unit 17 is disposed in the middle of the first transport path 14. The rotary punch unit 17 is driven a predetermined time after the entrance sensor SN1 detects the trailing edge of the copy sheet, and the copy is performed. It is controlled so as to punch a punch hole at a predetermined position at the rear end of the paper. Next, the rotary punch unit will be described. 2 is a front view of a main part of the rotary punch unit, FIG. 3 is a perspective view of the same, and FIG. 4 is a perspective view of a relay guide unit. In these figures, P is copy paper. The punch 21 protrudes from the rotating shaft 22, and the dies 23 are respectively fitted and fixed to the rotating shaft 24, and a hole 25 is formed in an extension piece on the outer peripheral portion. A gear 26,
27 comrades are engaged and fixed, and the punch 2
1 and the die 23 are rotated in synchronization with each other, and the tip of the punch 21 is fitted into the hole 25 of the die 23. Thus, the copy paper P is sandwiched between the copy paper P being conveyed.
Drill a punched hole. The gear 27 is driven by a drive motor 30 via a gear 28 and a timing belt 29. The drive motor 30 is started and stopped under the control of a control device (not shown) based on a signal from a sensor SN2 that detects a rotation angle of the encoder 31 that rotates in synchronization with the entrance sensor SN1 and the rotation shaft 22 (24). Rotating shafts 22, 24 and drive motor 30
Are fixed to the side plates 32 and 33 and a support member (not shown), and the rotary punch unit 17 is configured as one unit. A reference pin 35 protrudes from an outer surface of the side plate 33, and the side plate 3 of the post-processing device main body 2 is provided.
By inserting the reference pin 35 into the hole drilled in 6, the side plate 33 (the rotary punch unit 17) is positioned on the side plate 36. On the other hand, a screw hole 32 a is formed in the side plate 32 facing the side plate 33, and the side plate 32 of the rotary punch unit 17 is fixed to the other side plate 34 of the post-processing device main body 2 with a set screw 37. The rotary punch unit 17 is fixed to the post-processing apparatus main body 2. When the rotary punch unit 17 is unnecessary (or when another unit is required), for example, a relay guide plate unit 41 as shown in FIG. By attaching in a similar fixing method, it is possible to configure the apparatus without interfering with other processing. The relay guide unit 41 includes two guide plates 41a, 4
1a is provided to form a conveyance path for the copy paper P. In the above embodiment, collation, sorting,
By providing copy paper processing means for processing while transporting the copy paper P in the first transport path 14 for transporting the copy paper to the processing tray for bookbinding, secondary processing such as perforation is performed at high speed. As a result, it is possible to perform secondary processing of the copy paper P and composite processing such as collation and bookbinding. In the above embodiment, the use of the rotary punch unit 17 makes it possible to cope with high productivity. In the above embodiment, since the copy paper processing means is constituted as a unit, it is possible to arbitrarily select necessary functions. In the above embodiment, the copy paper processing means (17) can be easily attached to and detached from the post-processing apparatus main body 2 by, for example, the reference pin 35 and a fixing screw. Can easily accommodate expansion. [0027] [Effect of the Invention] According to the first aspect of the invention, since the mounting detachably the punching device in the middle of the conveying path, or without perforating apparatus, commonality of apparatus for mounting the punching device This makes it possible to easily respond to the need for or not to require drilling processing by the user, and to make the drilling machine perform at high speed.
And the post-processing mechanism of the processing tray can be simplified. [0029]
