Abstract

PURPOSE:To enable automatic feed of a cover, by a method wherein a paper feed table, a separating means, and a feeding means for a cover are located separately from a printing paper receiving means, and the feeding means is coupled to a stack means through a guide. CONSTITUTION:When a cover is needed, the presence of the cover is detected by a sensor 55, and based on the detection, a paper feed roller 7 is driven at a timing at which the cover 3 is fed to a delivery part B before a duplicating paper 1 for a first item is conveyed to the delivery part B. The cover 3 is placed on an intermediate tray 33 of an intermediate stacking part D through delivery rollers 15, 16 and a guide 27, and is orderly arranged in a position with the aid of a push plate 37. The cover 3 passes through a pinch roller 11, and through detection of sensors 56 and 57, duplicating papers are orderly fed from a duplicator 1 to an intermediate stacking part D. After one set of the papers are fed, a paper group on the tray 33 is fed to a finishing part E through a roller 39 with the aid of a belt 36. This also permits simultaneous supply of the cover.

inot; tomi1toi・to1 In conventional bookbinding equipment, the printing paper is stacked and aligned, and a finishing machine, such as a stapler (a machine that binds with U-shaped buttons like a gisu), Bookbinding devices that bind printed paper are known. When binding printed paper, it is required to bind at least one of the front and back covers inside the printed paper. Conventionally, the cover and back cover are bound separately from the printed paper. A device is used that supplies only

Therefore, two types of equipment, a bookbinding machine and a cover supplying machine, are required, which has the drawback of requiring a large amount of space and a large amount of cost. In particular, when binding copies of paper from a copying machine, a simple and inexpensive binding device is required.
Separately, cover supply bag τ! (There was a problem that it was too expensive to prepare for the war.

The copy paper that has been bound with LS (staple) or with holes (in this store, binding includes not only the binding work but also the perforation work) is placed in the 1-1 exit position. The guide bell 1-44 moves to eject stack f!
It is served to the same person.

Jul-out stack part J? The first output tray 52 has a tray 52 for stacking papers, and a height detection lever 54 for detecting the height of the upper end surface 53 of the paper stacked on the first output tray 52.

Discharge [・The ray 52 can be structured to be extracted like an extractor, or can be configured to move forward or backward (in the left-right direction in the figure) by about 30+U, or to move back and forth. . This movement works so that, for example, the parts of the lily pads do not overlap.

The height detection lever 54 may be used to detect the height of the copy paper so that the ejection tray 52 is sequentially lowered or raised.

The present invention will be described in detail.

When the document start button of the document supply device of the copying machine 1 is pressed, the bookbinding device 2 first starts supplying the cover,
Thereafter, the copy paper is fed from the copying machine 1, and when a predetermined number of copy sheets have been fed, the back cover is supplied again and the paper is stacked and aligned one by one at the intermediate stacking section. The first group of copy sheets arranged together with the cover is sent to the finishing section E, where the finishing machine 48 performs bookbinding operations such as binding or punching.
Thereafter, 1'') is output to the IJI output stack section F.

This will be further explained in AT' 1111 below.

When binding a book, there are cases in which both the front and back covers are required, and there are cases in which only either the front and back covers are required, and which mode to choose.'; j
5! I) I! This can be specified using a button.

If a cover is required, copy machine 1 to 1j'j
Before the Ll copy & IE is sent to the intermediate stacking section, the presence of the cover is detected by the sensor 55, and the cover is sent to the intermediate stacking section. For this purpose, the paper feed roller 7 to a part of the feeder is rotated at least at the timing when the front sheet passes through the delivery section B before the first page of copy paper reaches the delivery section B.

Since the cover and back side ♀1 (generally use thicker paper than copy paper, the feeder part A needs to have a mechanism that can reliably feed thick paper. When using the surface binding device 2 with RR4, By placing a set of sheets with aligned pages on the feed tray 4 of the feeder part A, all the sheets are sequentially fed from the feeder part A, and a set of books is bound in the finishing part E. Therefore, the feeder part Δ needs to have a mechanism that can reliably feed copy paper and the like.

The cover sheet is sent out by the rotation of the paper feed roller 7, and is delivered to the delivery rollers 15 and 16 of the delivery section B.

When the bookbinding device 2 is designated by a push button to perform bookbinding operations such as hole punching and stabilization (Bosotigis binding), the branching arm 17 passes through the first reversing guide and is moved to the discharge roller 3.
The passage leading to 1 and 32 is open. Therefore, the cover sheet is placed on the intermediate tray 33 in the intermediate stacking section by the discharging rollers 31 and 32, and aligned at a predetermined position by the pressing plate 37.

When it is desired to perform processing by interruption or to eject copy paper without so-called bookbinding, the branch arm 17 is switched to the position where it opens the path to the outlet 29, and the paper sent out from a part of the feeder is ejected from the outlet 29. 29 to the output tray 30 and the next machine, and the copy paper from the copying machine 1 is sent out from the outlet 29 to the output I-ray 30 and the next machine. Nao'I? It is also used to advance the cover when the page is large.

Copies C that are continuously sent one after another from the copying machine 1 without a break
&;I Reception 1 Cola 19.20 and conveyance speed 1iII Sent to adjustment section C. The circumferential speed of the receiving rollers 19 and 20 is the same as the conveying speed of the copying machine 1, but it is higher than that>'I i'
The speed has increased by ii.

Even if the copy M copy i1E is curled in one direction, it is reliably guided by the copy presser foot 25 and placed on the top of the conveyor heddle 24.

Depending on the type of saw mode selected and the bookbinding work performed by the binding machine 48, such as stabilization, hole punching, number of sheets, or thickness, the cover may not be marked or not.
The peripheral speed of the conveyor loop 1-24 is selected.

In the case of a mote that uses a cover, the sensor 56 detects that the cover is sent out by the binding roller 11;
Passing 1'-J-ra 15.1G means 1 pin! The copy kill was detected before it was detected by J'-'57! J--2], the cover is transferred to the transfer roller 1.5.
．． If it is at 1G, then Q, delivery, roller 15.1
In order to prevent the copy paper from advancing into the transfer belt 6, the circumferential speed of the conveyor belt 24 is controlled to be low.

When driven at this low speed, the conveyor bell 1-24
On the top of the sheet, a portion of the front part of the succeeding copy sheet rests on the rear part of the preceding sheet, so that they are arranged one on top of the other, like an arrangement of tiles. It is preferable to control the circumferential speed of the IM feeding route 24 so that the distance between the leading edges of adjacent copy sheets does not become too small, for example, so that it does not become less than about 151,111. If the paper leading edge interval is too short, the two sheets of copy paper will remain overlapped and be sandwiched between the delivery rollers 15 and 16, which is not preferable. When the paper leading edge interval is about 15 fins, the transfer roller], 5.16 allows two adjacent copy sheets to be sent out in a separated state without overlapping.

By conveying the copy sheets fed in at high speed in a stacked arrangement in a shingled pattern, it is possible to provide sufficient time for feeding the front cover to the intermediate stacking section.

-I that the cover has passed the delivery roller 15.16! After the sensor 57 detects 1, the circumferential speed of the first transfer roller 1-24 is gradually increased until it reaches the same speed as the transfer rollers 15 and +6.

The conveyance speed of a predetermined number of copy sheets as one set is adjusted t'! l
(When the back cover is sent from C to the intermediate stacking section, the back cover is sent in. At this time, at the stage of receiving the next set of copy kills, the peripheral speed of the conveyor bells 1 to 24 is reduced, and the back cover and The time required to feed the next set of covers is made to wait at 11 feed bells) and 24. If the back cover is not needed, the next cover is fed or is placed on standby.

According to the h sentence 11, the middle 1 and the middle 1 of the middle 1-ray 33 of the middle stacking section 31 and 33 are reversed and stacked sequentially as 1 and lower 1. At this time, each sheet is aligned each time it is fed by a reciprocating push plate 37.

By entering the size of the roughening paper, press 4.
The length of the reciprocating motion of M31 is selected.

If necessary, align the edges of the paper with a similar structure G,
It is possible to align them using a guide within one section.

When it is confirmed that the last copy sheet or back cover of a set of sheets has been fed, the I-Rayheld 36 moves the push plate 37 in the direction of pushing the aligned sheets forward, that is, to the left in the figure. The aligned sheets of paper on the intermediate tray 33 are sent out toward the delivery roller 39 while being pushed as they are.

One push plate 37 may be provided on the tray belt 36 in the circumferential direction thereof, or two or more push plates 37 may be provided at predetermined intervals, as required.

When it is confirmed that the copy paper group has passed the position of the feed roller 39, the arm 41 is moved and the feed roller 39 is moved from the position away from the lay belt 36 to the position where the paper is tray belted, and the copy KIE group is moved. It is sent out by the sending roller 39 and the tray heald 36.

The group of copy sheets is fed into the finishing section E by inverting the entire group of copy sheets aligned by the second reversing guides 42 and 43. When the leading edge of the group of copy sheets is detected by the sensor 60, the driver 1 II cola 45 is driven by the motor, and when it reaches the position of the receiving roller 47, the receiving roller 45 is loaded. ;l:
It is moved from a standby position away from the I cola 65 to a position in contact with the group of copy sheets by the action of a solenoid or the like, and presses the group of copy sheets against the roller 65. The receiving roller 47 is driven in synchronization with the drive 'IJ-roller 45 even when it is not in contact with the receiving roller 47. Distance system 1 initially set from the contact point P1 of tray belt 1-1-ra 45 and receiving belt 1-ra 47 of one intermediate stuff kink part and positional deviation 'ri2 between sensor 60 and point P1 are added. Distance! illt (li
+II 2-a) One push plate 49 is waiting in the device. A sensor 61 is provided at a selected position corresponding to the sensor 4159 in the intermediate methanol ring section l).

When the motor is turned on with the leading edge of the copy paper 11Y reaching the sensor 60, the push plate 49 reaches the point ljli where the 1&end of the copy paper group has passed the point P] and after the rear end of the copy paper group 11Y has passed the point P. jl by receiving roller 47 and drive 1 coke 45
j) Even if the number of copies is 41<, the group of copy sheets can be generally fed once by the push plate.

The group of copy sheets is guided by the guide bell l-44 and the tray 63 and fed into the notch-shaped entrance of the paper tray iJM48. The motor is stopped when the push plate 49 has pushed the group of copy sheets from the position of the entrance strainer 64 to the distance-inclusive position.

By reciprocating the push plate 49 while the group of copy sheets is in contact with the positioning member 64 which also serves as a stopper at the entrance of the finishing machine 48, the group of copy sheets aligned at the intermediate stacking section is slightly moved during transfer. Even if they are misaligned, you can re-align them. The group of copy IEs, which are placed in the finishing machine 48 in an aligned state, are subjected to bookbinding finishing operations such as perforation binding or posozi binding under the action of the drive roller 50.

When the bookbinding work is completed, the return lever 64, which also serves as a positioning section of the finisher 48, is actuated by the drive shaft 50 to push the copy paper out of the entrance. The return lever can be installed separately from the inlet positioning part 64.

Thereafter, the guide bell i-44 moves to the position indicated by the chain line in the figure, the guide bell I-44 is driven, and the group of copy sheets is moved to the position indicated by the chain line in the figure.
- 44 is pushed out to -1- of the υ1 paper tray 52 by the push plate 49. ... A servo motor, a stenoping motor, etc. can be used as the drive motor.

The height detection rod 54 detects the height of the highest copy sheet in a group of copies, and the height of the paper is adjusted from 1 to 8 so that the group of copies can be ejected accurately. surrounding. For this reason, the paper ejecting tray 52 is supported by, for example, a pantograph mechanism, and is configured to be able to freely move downward.

In the example of bound copy paper, if the stapled positions overlap, the portions will bulge, so in order to prevent this, the 1/1 paper tray 52 is set up every time a group of copy papers is fed. Each time, the paper tray 52 supported by a ball or the like is moved back and forth or left and right.

9L-US According to the present invention, it is possible to iM a bookbinding apparatus equipped with both a system for supplying a front cover or a back cover and a system for receiving and transporting printed fflE. According to the present invention, paper can be supplied at any time in addition to the printing paper, rather than the cover, so it has become possible to provide partitions of any number of printing papers.
