DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper discharge storage device coupled to an image forming apparatus such as a simple printing device or a copying machine, and more particularly to a receiving device for receiving one of a plurality of bin members arranged in a stacked state. The present invention relates to a paper discharge storage device equipped with sheet guide means for expanding an entrance by rotation of an opening / closing cam and simultaneously deflecting a sheet on a conveying surface by a deflection claw and inserting the sheet into a receiving entrance.

[0002]

2. Description of the Related Art An image forming apparatus such as a simple printing apparatus or a copying machine is provided with a paper discharge storage device for storing image forming paper discharged therefrom. This type of paper discharge storage device guides sheets to be discharged to a paper discharge tray in the non-sorting mode, and sequentially stacks the sheets on the paper discharge tray. On the other hand, in the sorting mode, the paper discharge storage device guides the sheets to be discharged to a bin unit composed of a plurality of bin members arranged sequentially one above the other, and sequentially to a receiving opening of a predetermined bin member in the bin unit. The sheet is guided by a sheet feeding device, and the sheet is inserted into a receiving port of a predetermined bin member and stored in the bin member. Here, in the sorting mode, when guiding each sheet on the conveyance surface of the conveyance device to the reception port of each bin member, the reception port of each bin member in the bin unit is moved to face the fixed sheet deflection position. What makes you
Using a deflecting claw that moves along the conveyance surface of the conveyance device and an opening / closing cam that sequentially moves each bin member in the bin unit up and down, a receiving port of each bin member that moves up and down and a sheet insertion that moves on the conveyance surface. There is known one that adopts each opening moving method of facing a position.

For example, in a sheet handling apparatus disclosed in Japanese Patent Publication No. 61-9218, all the bin members in a bin unit are moved up and down at the same time, so that a first diverting member provided on a vertical conveyance path can be used. The second diverting member is sequentially switched, and the sheets are alternately inserted into the receiving port of the bin member by the first diverting member and the second diverting member. In this case, the sliding area of the bin unit is reduced by half, compared with a device in which a single sheet deflection position is set by a single deflection member and the bin unit is moved up and down for sorting. Occupied space can be reduced, and the size of the apparatus can be reduced. On the other hand, the collating apparatus disclosed in Japanese Patent Publication No. 3-6104 has a cylindrical cam that sequentially engages with each bin member in the bin unit. In this case, by rotating the cylindrical cam, the receiving port of one bin member among the plurality of stacked bin members is enlarged, and a sheet is inserted into the receiving port by a sheet feeding device that moves together with the cylindrical cam. Sheets can be sorted into bin members. In this case, the size of the apparatus can be reduced as compared with a bin unit of a type in which a plurality of bin members that always open the receiving port are arranged.

[0004]

By the way, as the speed of an image forming apparatus has been increased, it has been required to improve the sorting processing speed of a paper discharge storage apparatus which performs sorting processing in synchronization with the image forming apparatus. .

However, in the sheet handling apparatus disclosed in Japanese Patent Publication No. 61-9218, the receiving port of the bin member into which the sheet is inserted is switched every time a sheet is inserted into the bin member by the second diverting member. That is, the switching time given here is the same as that of the apparatus in which a single deflecting member switches and moves the bin unit every time the first sheet is deflected. This is a very short time from when the third sheet is inserted into the bin member by the second diverting member to when the third sheet reaches the first diverting member, which is sufficient as a measure for improving the sorting processing speed. It is not a thing.

On the other hand, in a collating apparatus disclosed in Japanese Patent Publication No. 3-6104, a plurality of bin members for sheet insertion are stacked, and one bin member is connected to one side of an adjacent bin member by rotation of an opening / closing cam. The sheet is further moved to the other side to enlarge the receiving opening of the one bin member, and at this time, the sheet is inserted into the receiving opening of the one bin member by the sheet feeding device which moves together with the cylindrical cam. In the sorting process in this case, the sorting process can be performed by driving the opening / closing cam and the sheet feeding device to move only the bin member above one bin member up and down. However, in this case, the opening / closing cam has a central hole formed in a rectangular shape, and the opening / closing cam uses a drive shaft having a rectangular cross section capable of permitting axial sliding and transmitting rotation. In this case, the workability of the drive shaft is poor, and it is necessary to simultaneously slide while receiving the rotational force, so that a large force is applied to the central hole as the bearing. For this reason, the bearings are also severely worn, and are not suitable for high-speed rotation and high load at the time of opening and closing the bottle member, which is a problem in improving the sorting processing speed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper discharge storage device capable of increasing the sorting processing speed and improving the durability.

The sheet is deflected, and the sheet is moved to the first bin tray 6 where the trunnion 22 abuts immediately below the opening / closing cam 12.
The sheet which is inserted into the receiving port a of the printer, that is, the sheet taken into the discharge section facing position Z by the take-in section conveying means 8 and the sheet deflecting means 14 is conveyed in a U-turn state and is placed with the image surface facing downward. Is done. At this time, the first bin unit 7 side end fence 24 switches and holds the position in accordance with the sheet size which has been detected in advance, so that the sheet inserted from the receiving port a side can be predetermined in accordance with the size. To stop at the time of stacking.

When this first sheet is inserted into the receiving port a of the first bin tray 6, a bin drive signal for permitting bin feeding is output in response to a detection signal from the sheet sensor S1 (see FIG. 5). In response to this signal, the stencil printing apparatus 2 switches to the second bin unit operation mode, drives the drive motor 29 of the opening / closing cam drive means 13 and rotates both the front and rear opening / closing cams 12 by one rotation. One in this one revolution
The trunnion 22 of the second bin tray 6 moves relatively downward by the distance L1 above the trunnion 22 of the second bin tray 6. At this time, the trunnions 22 of the second bin tray 6 move downward along the cam grooves 122 of both opening / closing cams 12 to overlap directly above the trunnions 22 of the first bin tray 6, and can move further downward. Therefore, the two opening / closing cams 12 and the deflecting claw 35 move upward together with the lifting frame 11, and when just one rotation, the two opening / closing cams 12
Is the trunnion 22 of the second bin tray 6 whose lower edge is
And reach the position where it contacts.

At this time, the receiving port a of the second bin tray 6
At the same time, the claw solenoid 95 is turned off, and the claw solenoid 95b of the second sorting section B is turned on.
Switch to 1 and hold.

In this state, when the second sheet passes through the deflecting claw 35 and reaches the deflecting claw 35b, it is deflected there and the first bin tray 6 abuts on the lower edge of the opening / closing cam 12b.
Insert the sheet into b and store it. When the second sheet is inserted into the first bin tray 6b of the second sorting section B, a bin drive signal for permitting bin feeding is output in response to a detection signal from the sheet sensor S1 (see FIG. 5). In response to this signal, the stencil printing machine 2 returns to the first bin unit operation mode.

Here, the drive motor 29b of the opening / closing cam driving means 13b of the second sorting section B is driven to
b is rotated once, and the trunnions 22 of the second bin tray 6b are placed on the trunnions 22b of the first bin tray 6b.
b moves relatively downward by the distance L1. At this time, 2
The trunnion 22b of the second bin tray 6b overlaps right above the trunnion 22b of the first bin tray 6b and cannot move any further downward. When exactly one rotation is made, both open / close cams 12b have lower end edges of 2 cams.
The bin tray 6b reaches a position where it comes into contact with the trunnion 22b. At this time, the receiving inlet a of the second bin tray 6b is enlarged, and at the same time, the claw solenoid 95b is turned off, and the claw solenoid 95 of the first sorting section A is turned on. 35 is switched to the deflection position q1 and held.

In this state, when the third sheet reaches the deflecting claw 35 of the first sorting section A, it is deflected there, and the sheet is inserted into the second bin tray 6 contacting the lower edge of the opening / closing cam 12 and stored. Is done. When the third sheet is inserted into the second bin tray 6 of the first sorting section A, the operation continues thereafter as in the case of the first sheet, and the stencil printing machine 2
Hereinafter, the first and second bin unit operation modes are repeated, and when the sorted number of sheets are inserted into the receiving inlets a of the bin trays 6 and 6b of the first sorting section A and the second sorting section B by １ ／ each. The stencil printing apparatus 2 includes an opening / closing cam driving unit 13;
The rotation of the drive motors 29, 29b of 13b is stopped, and the claw solenoids 95, 95b are turned off. Further, when the sheets of the sorting number are inserted into the bin trays 6 and 6b of the sorting number,
The stencil printing machine 2 stops the drive motors 29, 29b of the opening / closing cam drive means 13, 13b of the first and second sorting units A, B after rotating them in reverse, and enters the standby state at the above-mentioned reference position, which is the lowermost end. enter.

During such sheet sorting operation, the deflection claw 3
The sheet sensor S1, which is a reflection-type optical sensor disposed in the concave surfaces 352 and 352b of the fifth and 35b, performs a sheet detection operation. Each time a sheet is inserted from the stencil printing apparatus 2 into a predetermined bin tray 6, 6b, the sheet sensor S1 can reliably recognize the sheet. When the control system of the stencil printing apparatus 2 cannot detect a sheet within a predetermined time or keeps detecting the sheet, it determines that a sheet conveyance jam has occurred and stops the printing operation. Is displayed. Accordingly, there is no need to provide a sheet sensor S1 for detecting that a sheet has been inserted into all the bin trays 6, 6b, and if only one deflection claw 35, 35b is provided, the bin trays 6, 6b
It is possible to detect insertion of a sheet into a sheet. In parallel with this,
A second plate making process is performed. Then, the stencil printing apparatus 2 sequentially discharges the sheets corresponding to the second document on which the image is formed from the paper discharge port 3 by the sorting number. At this time, the paper with the plate is controlled to be discharged to the discharge tray 15 as described above.

In this case, when the first sheet corresponding to the second document is conveyed along the taking-in section conveying means 8, a sheet detecting switch (not shown) on the taking-in section conveying means 8 outputs a sheet conveying signal. The stencil printer 2 enters the first bin unit operation mode, turns on the claw solenoid 95 of the first sorting unit A, turns off the claw solenoid 95b of the second sorting unit B, and moves the deflecting claw 35 to the deflection position q1. , The deflection claw 35b is held at the retracted position q2. As a result, the sheet that has reached the deflection claw 35 is deflected, and the sheet is placed in the standby state in the standby state.
The first sheet is stacked on the previous sheet with the image surface of the first sheet facing downward on the bin tray 6 with. At this time, the sheet sensor S1 provided on the deflection claw 35 is turned on in the same manner as described above, and a bin drive signal allowing the bin feed is output. In response to this signal, the stencil printing machine 2 is set to the second bin unit operation mode. Then, the drive motor 29 of the opening / closing cam drive means 13 rotates both the front and rear opening / closing cams 12 in the same manner as in the case of the first document, and moves the trunnion 22 of the second bin tray 6 from the bottom by the distance L1. To move downward.

As a result, the two opening / closing cams 12 and the deflecting pawl 35 move upward together with the lifting frame 11, and the lower edges of the two opening / closing cams 12 move to the trunnions 22 of the second bin tray 6 from the bottom.
Abut. At this time, the receiving port a of the second bin tray 6 from the bottom is enlarged, and at the same time, the claw solenoid 95 is turned off.
The claw solenoid 95b of the second sorting section B is turned on, whereby the deflection claw 35 is switched to the retreat position q2 and the deflection claw 35b is switched to the deflection position q1 for holding. In this state, when the second sheet reaches the deflecting claw 35, the second sheet passes through the deflecting claw 35. When the second sheet reaches the deflecting claw 35b of the second sorting section B, the lower end edge of the opening / closing cam 12b contacts the trunnion 22b. 6b is inserted into the receiving port a, and is stacked on the previous sheet. When the second sheet is inserted into the bin tray 6b, the sheet sensor S1 provided on the deflecting claw 35b as described above.
Is turned on, and a bin drive signal allowing bin feed is output. In response to this signal, the operation returns to the first bin unit operation mode. Thereafter, the first and second bin unit operation modes are repeated, and the first sorting unit A and When 仕 of the sorted number of sheets are inserted into the receiving openings a of the bin trays 6 and 6b of the second sorting section B, the stencil printing apparatus 2 opens and closes the opening and closing cam driving means 13 and
The rotation of the drive motors 29, 29b of the 13b is stopped, the claw solenoids 95, 95b are turned off, and the drive motor 2 of the opening / closing cam drive means 13, 13b of the first and second sorting units A, B is driven.
9, 29b are stopped after being rotated in the reverse direction, and the apparatus enters a standby state in which the sheet corresponding to the third document is carried in at the above-described reference position at the lowermost end.

As described above, when the sorting mode is selected, the sheets on which images are formed are sequentially sorted on the bin trays 6 and 6b of the number of prints according to the predetermined number of originals from the first original. After the stacking and the printing, the sheet bundles of the number of documents stacked on the bin trays 6 and 6b are sequentially taken out to the near side by the operator from between the left vertical frame portion 204 and the right vertical frame portion 205. Become. In some cases, after printing, each sheet bundle on each bin tray 6, 6b may be stapled by the stapler 26, 26b and then taken out.

In this embodiment, the opening / closing cams 12, 12
Using the position where b is the lowermost position as a reference position, the lifting frame 11,
Although the sorting operation is performed while moving the bins 11b from bottom to top, the trunnions 22, 22b move from top to bottom, and as a result, the bin trays 6, 6b
Is moved from top to bottom, so the load is reduced and it is easy to respond at high speed. Therefore, if this effect is not desired, the lifting frames 11, 11b may be moved from top to bottom with the position where the opening and closing cams 12, 12b are at the uppermost end as a reference position. Of course, open / close cam 1 for each document
After moving 2,12b from the top to the bottom without returning to the reference position, the next document may be moved from the bottom to the top.

As described above, in the paper discharge storage device 1 shown in FIG. 1, by attaching the retrofit frame 120 to the base frame 20, the bin trays 6 and 6b of the first and second bin units 7 and 7b are connected. All sheets can be sorted and stored,
It can easily cope with an increase in the number of sheets. In particular, since the first sheet guide means 130 independently feeds the bin tray 6 of the first bin unit 7 and the second sheet guide means 130b feeds only the bin tray 6b of the second bin unit 7b, the first and second sheet guide means 130 operate independently. Two sheet guide means 130, 13
The load received by the switching operation 0b at the time of the switching operation is divided into two and reduced, so that the sorting processing speed can be increased and the durability can be easily improved.

Further, when the number of sorts always required by the user is small, the taking-in section conveying means 8, the first bin unit 7, the first vertical conveying means 19, and the first sheet guiding means 130 are mounted on the base frame 20. Can be used, and the user always needs a relatively large number of sorts, a retrofit frame 120 is connected to the upper end of the base frame 20 and then the retrofit frame is attached. In the body 120, the second bin unit 7b, the second vertical conveying means 19b, and the second sheet guiding means 130
b, and the first and second vertical transporting means 19 and 19b, which are arranged vertically, the first and second bin units 7, 7b,
The first and second sheet guide means 130 and 130b can be linked to each other, so that the usage mode can be diversified. Further, the first and second bin unit operation modes are alternately repeated,
The permissible operation time allowed for bin feeding of each sheet guide means 130, 130b can be twice as long as when only a single sheet guide means is used, and in this respect, the sorting processing speed is increased. And durability can be easily improved.

Further, the opening / closing cam 1 is mounted on the lifting frames 11 and 11b.
2, 12b and opening / closing cam driving means 1 as the driving means thereof
3, 13b, the deflecting claws 35, 35b and the claw switching means 36, 36b are attached and moved up and down integrally.
The bearing portion Y that receives the rotation of the opening / closing cams 12 and 12b and the front pivot portions 27 and 27b on the side of the lifting frames 11 and 11b are separated and independent, so that the load received by each bearing portion Y is relatively reduced, and the bin opening and closing operation is performed. It is easy to increase the speed at the time, and the durability is also improved.
Moreover, in this case, even if the lifting frame 11, 11b moves to any position in the vertical direction, the first and second deflecting-side transfer surfaces f, 11
After being deflected by the deflection claws 35, 35b on the fb, the sheet deflected toward the receiving opening a of the bin trays 6, 6b abutting on the lower edges of the opening / closing cams 12, 12b has a constant deflection angle. The sheet can be guided to the receiving port a, and a stable sheet guiding function can be secured. Further, the opening / closing cam driving means 13, 13 b controls the rotation of the driving motors (driving sources) 29, 29 b supported on the lifting frames 11, 11 b by the connecting shaft 34,
34b and a plurality of gear trains 32, 33, 32b, 33b, and can be transmitted to a plurality of opening / closing cams 12, 12b.
The plurality of opening / closing cams 12 and 12b can be reliably and rotationally driven.

As described above, the paper discharge storage device 1 shown in FIG.
And the first sorting unit A
And the second sorting unit B are connected and linked in a stacked state. Instead, as shown in FIG. 15, a second paper discharge storage device having a substantially similar configuration to the paper discharge storage device 1 is used. 1B to 2
A configuration in which a series is connected may be adopted. In this case, the second paper discharge storage device 1B is different from the first paper discharge storage device 1 in that the paper discharge tray 15 and the first switching unit 16 are eliminated, and the single paper discharge unit transport means 8B is provided. Only the difference. In this case as well, each drive source of the paper discharge storage device 1 and the second paper discharge storage device 1B is connected to the control means (not shown) in the stencil printing device 2, and thereby the switching operation is performed. .

When such a configuration is adopted, at the time when the sheets are sorted into the first sorting section A and the second sorting section B of the sheet discharge storage device 1, the second switching section 18 is moved to the normal position t1 (see FIG. 8). And the sheet of the horizontal transport unit 17 is
It is deflected to the second vertical transport means 19, 19b, on which the first and second bin unit operation modes are alternately repeated. Next, at the time when the sheets are sorted into the first sorting section A 'and the second sorting section B' of the second sheet discharging and storing apparatus 1B, the second switching section 18 is switched to the double position t2 (see FIG. 8) and held. The sheet of the horizontal conveying section 17 is conveyed toward the discharge section opposing position Z ′ of the second discharge storage apparatus 1B, and then the first sorting section A ′ of the second discharge storage apparatus 1B and The first and second bin unit operation modes for sorting sheets to the second sorting section B 'are alternately repeated.
In this case, the same operation and effect as those of the paper discharge storage device 1 in FIG.

In each of the above embodiments, the tip of the deflecting claw 35, 35b is brought into contact with the surface of the endless belt 48 to scoop up the tip of the conveyed sheet. However, as shown in FIG. It is also possible to adopt a configuration in which the belt enters the inside of the endless belt 48. The positional relationship with the endless belt 48 is as shown in FIGS. As shown in FIG. 17, the deflection claw 35c in the present embodiment has a toe 351.
Is formed with a notch portion 512 into which the endless belt 48 enters, and is formed in a comb-like shape as a whole. Due to this shape, each toe 351 enters the gap between the endless belts 48 at the deflection position of the deflection claw 35c. In FIG. 17, the claw switching means 36 is omitted.

As described above, the deflecting claw 35c is formed in a comb tooth shape, and the toe 351 is formed on the surface of the endless belt 48 (deflecting side conveying surface f).
If it is made to sink more, the scooping of the sheet is assured, and it is not necessary to increase the tip precision of the toe 351.
By the way, as described above, the guide plate 500 located on the back side (inward side) of the endless belt 48 has a function as close to the endless belt 48 as possible within a range that does not hinder the rotational movement of the endless belt 48. However, contact with the deflection claw 35c is a problem. This is because the deflecting claw 35c is frequently swung and may be worn out early by contact with the guide plate 500.

In this embodiment, in order to deal with this problem, FIG.
As shown in FIG. 6, a mylar 514 as a cushioning member is fixed to the back side of each toe 351. Due to the presence of the mylar 514, the contact between the guide plate 500 and the toe 351 becomes a soft contact, so that the impact that cannot be absorbed by the stroke adjusting spring 118 is reduced, and the collision noise can be reduced.

Although the above-described paper discharge storage devices 1 and 1B are connected to the stencil printing device 2, a configuration in which the paper discharge storage devices 1 and 1B are connected to the paper discharge unit of the electrophotographic copying machine may be adopted instead. In this case, the same operation and effect as described above can be obtained.

According to the third aspect of the present invention, the first sheet guiding means is driven in the first bin unit operating mode to store a sheet in the first bin unit, and the second sheet guiding means is operated in the second bin unit operating mode. , And the operation of accommodating sheets in the second bin unit is alternately repeated, and the permissible operation time allowed for the bin feeding operation of each sheet guide means is twice as long as when only a single sheet guide means is used. In this respect, it is possible to easily increase the sorting processing speed and improve the durability.

According to the fourth aspect of the present invention, in each of the first and second sheet guide means, the opening / closing cam supported by the elevating frame does not slide in the up-down direction itself, and is equivalent to the feed. The vertical sliding part and the pivoting part of the opening / closing cam can operate independently and smoothly at high speed.
Their durability is also improved. In addition, regardless of the vertical position of the lift frame, the lift frame is deflected by the deflecting claw on the deflecting side transport surface, and then deflected toward the bin member receiving port that contacts the lower edge of the opening / closing cam. The deflection angle of the sheet becomes constant, and the sheet can be reliably guided to the receiving port, and a stable sheet guiding function can be secured.

According to the fifth aspect of the present invention, the rotation of the drive source supported by the lifting frame can be transmitted to the plurality of opening / closing cams via the connecting shaft and the plurality of gear trains. And can be driven to rotate.
