Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment] (Recording Material Processing Apparatus) FIG. 1 shows a recording material processing apparatus 1 according to an embodiment of the present invention. A recording material processing apparatus 1 shown in FIG. 1 is connected to a recording material discharge side of a copying machine 2 as an image forming apparatus, and a recording material (sheet-like paper, plastic, etc.) discharged from a discharge roller pair 3 of the copying machine 2. A film or the like is introduced into the inside of the recording material, so that a filing hole is formed in the recording material, and a stapling process is performed on a bundle of the recording material.

The recording material processing apparatus 1 includes a housing 4 having a substantially rectangular parallelepiped shape, and a recording material carry-in port 5 is formed at a portion of the copying machine 2 facing the discharge roller pair 3. At a position adjacent to the recording material carry-in port 5, a punching means 6 for piercing the recording material for filing is arranged.

The punching means 6 guides the recording material fed into the housing 4 from the recording material entrance 5 by the pair of discharge rollers 3 on the copying machine 2 side, between the upper and lower guide members 7a and 7b. ing. The punch processing means 6 positions the leading end of the recording material located between the upper and lower guide members 7a and 7b by temporarily stopping it with a stopper (not shown), and positions the punch 8 for punching on the lower guide member. 7b is moved up and down to engage with a punch receiving hole (not shown) of
Drill a hole at the end of the recording material. Next, the punching means 6 retracts a stopper (not shown). As a result, the recording material is sent to the curl removing device 10 by the discharge roller pair 3 on the copying machine 2 side. It should be noted that the punching operation time of the punch processing means 6 depends on the stopper and the copying machine 2.
This is an extremely short time in which the recording material between the pair of discharge rollers 3 on the side is slightly curved. Therefore, there is no possibility that a problem occurs in conveying the recording material.

The decurling apparatus 10 includes two curling roller pairs 11 and 12. One of the two sets of curl removing rollers 11 and 12 performs curl removal in exactly the opposite direction.

The recording material sent from the decurling device 10 is transported by a pair of transport rollers 13 to a first recording material transport path 14.
Alternatively, it is sent to the second recording material conveyance path 15. Here, the first recording material conveyance path 14 and the second recording material conveyance path 15
It can be switched by. That is, when the branch claw 16 closes the second recording material conveyance path 15 and opens the first recording material conveyance path 14 (when the branch claw 16 moves to the position indicated by the dotted line in FIG. 1), the recording sent from the conveyance roller pair 13 is performed. The material is guided to the branch claw 16 and the first recording material conveyance path 14 and is conveyed to the nip portion of the non-sort discharge roller pair 17. The recording material is a non-sort discharge roller pair 17.
Is discharged to the non-sorting discharge tray 18. Further, the branch claw 16 closes the first recording material conveying path 14 and
When the recording material transport path 15 is opened (when the branch claw 16 is at the position indicated by the solid line in FIG. 1), the recording material sent from the transport roller pair 13 is guided to the branch claw 16 and the second recording material transport path 15. It is transported to the intermediate tray 20 side.

The recording material moving in the second recording material transporting path 15 depends on the size.
The route guided up is different. That is, the intermediate tray 2
0 corresponds to the first to fourth recording media along the second recording material transport path 15 so as to correspond to the four types of recording media of the first to fourth sizes.
The four recording material loading means 22 to 25 are sequentially arranged.

First to third recording material loading means 22 to 24
Is a pair of carry-in rollers 26 to 28 and a pair of carry-in rollers 26
To 28, which are movable guide members (movable members) 30 to 32 located on the downstream side in the recording material conveyance direction. For example, the first recording material loading means 22 is configured to store the first-size recording material in the second recording material.
When the movable guide member 2 is transported through the recording material transport path 15,
6 moves to the dotted line position in FIG.
Is closed, and the recording material conveyed by the carry-in roller pair 26 is guided to the recording material receiving table 21. The movable guide member 30 of the first recording material carry-in means 22 moves to the solid line position in FIG. The recording material is reliably pushed onto the recording material receiving table 21 by hitting the rear end of the recording material. In this way, even if the recording material is curled, it is possible to prevent the trailing end of the curled recording material from being caught on the carry-in roller pair 26, so that a jam unlike the conventional example is less likely to occur. The second and third recording material loading means 23 and 24 have the same configuration as the above-described first recording material loading means 22, and the first and second recording material loading means 22 correspond to the recording material having the corresponding size. It functions in the same way as the recording material carrying means 22.

The fourth recording material carrying means 25 includes a carrying roller pair 33, a stationary guide portion 34 located at a downstream end of the second recording material carrying path 15, and a downstream side of the carrying roller pair 33 in the recording material carrying direction. It comprises a hitting member (movable member) 35 located. The hitting member 35 is supported so as to be swingable by a support shaft 36 attached to a frame fixed to the housing 4. The hitting member 35 is moved at a timing when the fourth size recording material is separated from the nip of the carry-in roller pair 33. 1 swings from the solid line position to the dotted line position, and strikes the rear end of the recording material. Thus, even if the fourth-size recording material is curled, the fourth recording-material carrying means 25 can prevent the occurrence of a jam similarly to the first recording-material carrying means 22 described above.

The above-described first to fourth recording material loading means 22 to
The recording material sent to the recording material receiving table 21 by any one of the members 25 is held up by the holding roller 37 and further sent downward in FIG. 1 by the holding roller 37. The pressing roller 37 stops rotating at the timing when the leading end of the recording material comes into contact with the receiving member 38 located at the lower end of the recording material receiving table 21. As a result, the leading end of the recording material carried into the recording material receiving table 21 is positioned by the receiving member 38 at the home position, and the carrying-in movement is stopped.

The receiving member 38 of the recording material receiving table 21 is
The front end of the recording material (the lower end of the recording material P in FIG. 2) is received, and a predetermined number of recording materials can be stacked. A holding member 40 made of a film-shaped plastic is attached to the receiving member 38, and the rising of the top surface on the leading end side of the stacked recording materials is suppressed by the elastic force of the holding member 40.

When a predetermined number of recording materials are stacked on the recording material receiving table 21, the width moving plate 43 is operated by the width moving mechanism 42 of the aligning means 41, and the width direction of the recording material (the paper surface in FIG. 1). (Perpendicular to the vertical direction).

When the aligning operation of the recording material bundle by the aligning means 41 is completed, a stapler (recording material processing means) 44 is operated, and a stapling process is performed on the leading end side of the recording material bundle.

The bundle of recording materials subjected to stapling is
Sorting discharge roller pair 46 by recording material moving means 45
To the nip. That is, when the driving pulley 47 is rotationally driven, the recording material moving unit 45 rotates the endless belt 5 wound around the driving pulley 47 and the driven pulley 48.
0 is driven to rotate counterclockwise, and the endless belt 5
1 is moved along the surface of the recording material receiving table 21 from the home position in FIG.
The bundle of recording materials is lifted up in FIG. 1 along the surface of the recording material receiving table 21, and the leading end of the bundle of recording materials is conveyed to the nip portion of the sort discharge roller pair 46 through the sort recording material discharge path 51. It is supposed to.

The bundle of recording materials is discharged onto a sort discharge tray 52 by a sort discharge roller pair 46. The operation of the sorting discharge tray 52 is controlled such that the upper surface position thereof is detected by the sensor 53 and the upper surface position is at an optimum height position for stacking a bundle of recording materials.

The recording material processing apparatus 1 takes into account the time required to perform a stapling process or the like on the recording material and the time required to discharge a bundle of recording materials to the sorting discharge tray 52, and the like. Roller pair 13 and carry-in roller pairs 26-28,
33 etc.).

(Detailed Structure and Operational State of Intermediate Tray) FIGS. 2 and 3 are diagrams for explaining the detailed structure and operational state of the intermediate tray 20 according to the present embodiment. As shown in these drawings, for example, one of the carry-in roller pairs 33 is formed of a rubber material and the other is formed of a resin material such as POM, and is formed in a width direction of the recording material P (perpendicular to the paper surface of FIGS. ) Are arranged at an interval in the direction, so that the conveying force is reliably transmitted to the recording material. The rear end of the recording material P is located between the carry-in rollers 33, 33.
A recording material hitting roller 54 in which plastic hairs acting to hit the side are planted is rotatably arranged.
The recording material hitting roller 54 is attached to one support shaft of the carry-in roller pair 33, and rotates with one of the carry-in roller pairs.

Each of the movable guide members 30 to 32 operates as described above to guide the recording material P onto the recording material receiving table 21, and also to transfer the bundle of the recording material P after stapling to the intermediate tray. When the recording material is discharged from
5, is swung to the position shown in FIG.
The guide surface 55a, 55b on the recording material receiving table 21 side and the surface 21a of the recording material receiving table 21 limit the width of the passage through which the bundle of the recording material P passes, and the leading end of the recording material P is moved to the pair of loading rollers 26 to
This prevents a bend or a jam from being caused by being caught on the cover 28. In addition, the movable guide members 30 to 3
2 guide surfaces 55a, 55b and surface 2 of recording material receiving table 21
1a is set smaller than the interval between the carry-in roller pairs 26 to 28 and the surface 21a of the recording material receiving table 21,
The recording material processing apparatus 1 can be adjusted according to the use environment and the like.

The hitting member 35 is accommodated in a retreating recess 56 of a stationary guide portion 34 fixed to the housing 4, and one end of the hitting member 35 is swung by a support shaft 36 supported by the stationary guide portion 34. Supported to be able. Then, as described above, after the leading end of the recording material P is detected by the sensor 57 (see FIG. 1) disposed on the upstream side of the intermediate tray 20, the hitting member 35 applies the recording material P to the carry-in roller pair 3.

5, when the bundle of the recording materials P after the stapling process is discharged from the recording material receiving table 21 (intermediate tray 20), the recording material P swings from the retracted position (the solid line position in FIG. 2) to the dotted line position in FIG. The upper surface of the recording material P is placed on the recording material receiving table 2
The recording material P is pressed at a position closer to one to suppress the lifting of the end of the recording material P. As a result, even when the end of the recording material P is curled, when the bundle of the recording material P is discharged from the intermediate tray 20, the end of the recording material P is caught by the carry-in roller pair 33, and the end of the recording material P is bent or jammed. Nothing happens.

The hitting member 35 is swingable by a solenoid (not shown), and is always retreated to the retraction recess 56 when the recording material processing apparatus 1 is stopped. As a result, the intermediate tray 20 can be easily pulled out of the housing 4. Although at least one hitting member 35 is sufficient, it is preferable to arrange a plurality of hitting members 35 in the width direction as shown in FIG.

The holding roller 37 is rotatably attached to the tip of the swing arm 58, and is connected to the driving source of the above-mentioned carry-in roller pair 33 via power transmission means such as a gear. The recording material P can be conveyed at the same speed as the recording material conveyance speed such as 33. Also,
The swing arm 58 is swingably supported by a stationary guide portion 60 fixed to the housing 4 via a support shaft 61, and the leading end of the recording material P is detected by the sensor 53 (see FIG. 1). The operation is performed in consideration of the time from when the pressing roller 37 reaches the ground contact position.
That is, the swing arm 58 is in the retracted position (solid line in FIG. 2) such that the pressing roller 37 is brought into contact with the surface 21a of the recording material receiving base 21 at the timing when the leading end of the recording material P almost reaches the contact position of the pressing roller 37. 2) to the dotted line position in FIG. The swing arm 58 is controlled to be retracted to the retracted position when the bundle of the recording materials P after the stapling process is discharged from the recording material receiving table 21 and when the recording material processing apparatus 1 is stopped. As a result, the work of discharging the bundle of recording materials P from the intermediate tray 20 is performed smoothly, and the intermediate tray 20 can be smoothly pulled out of the housing 4 at the time of a jam clearance or the like. As described above, the rotation of the pressing roller 37 is stopped at the timing when the leading end of the recording material P comes into contact with the receiving member 38. Note that the swing arm 58 is provided with the carry-in roller pair 3.
Drive control by linking to the power transmission means 3 through a gear or an electromagnetic clutch, or driving by a solenoid,
Further, the drive control may be performed by a forward / reverse rotation motor. As shown in FIG. 3, one pressing roller 37 is arranged at a substantially central portion in the width direction of the recording material receiving base 21. A plurality of pressing rollers 37 may be arranged at intervals so as to provide a conveying force.

As shown in FIG. 3, a pair of pressing members 40 are provided so as to press both ends in the width direction of the leading end of the recording material P, so as to prevent the leading end of the recording material P from rising. Has become.

32 or the hammering member 35, the carry-in roller pair 26-2.
The recording material P can be pushed into the recording material receiving table 21 by hitting the rear end of the recording material P in the vicinity of 8, 33 to prevent the rear end of the recording material P from being caught by the carry-in roller pairs 26 to 28, 33. Therefore, even if the recording material P is curled, the leading end of the recording material P which is later conveyed onto the recording material receiving tray 21 is positioned at the rear end of the recording material P already stacked on the recording material receiving tray 21. There is no snagging and jams are less likely to occur.

The intermediate tray 20 according to the present embodiment
Is transferred to a position where the leading end of the recording material P conveyed onto the recording material receiving table 21 comes into contact with the receiving member 38 of the recording material receiving table 21 by the pressing roller 37, and the pressing member 40 installed on the receiving member 38 Since the rising of the leading end of the recording material P is suppressed, the leading end position of the recording material P is positioned. Therefore, the work of aligning the recording material P before the stapling process is reliably performed, and the stapling process with high accuracy can be performed.

The intermediate tray 20 according to the present embodiment
, The bundle of the recording materials P after the stapling process is
When the recording material P is ejected from above, the movable guide members 30 to 32 and the hitting member 35 suppress the rising of the leading end of the recording material P, and the leading end of the recording material P moving on the recording material receiving table 21 is brought into the pair of loading rollers 26 to 28. , 33 are controlled so that the operation of the movable guide members 30 to 32 and the hitting member 35 is controlled, so that the recording material P discharged from the recording material receiving table 21 is bent or jammed. Can be prevented.

Further, since the recording material processing apparatus 1 according to the present embodiment includes the above-described intermediate tray 20 as a main part of the structure, the recording material P can be stapled without causing a problem such as jamming or bending of the recording material P. Processing can be performed smoothly, and the bundle of recording materials P after the stapling can be smoothly discharged onto the sorting discharge tray 52.

[Second Embodiment] The intermediate tray 20 of the present invention is not limited to the above-described embodiment, but may be configured as shown in FIG. That is, the intermediate tray 20 shown in FIG.

In the intermediate tray 20 shown in FIG. 4, the pressing roller 37 moves up and down by a solenoid or a cam (not shown) so as to come into contact with or separate from the recording material P. However, the intermediate tray 20 shown in FIG. 4 is the same as the intermediate tray 20 of the above-described embodiment except for the swing fulcrum position of the hitting member 35 and the operation configuration of the holding roller 37. Functions and effects substantially the same as those of the intermediate tray 20 of the embodiment can be obtained. Further, while the hitting member 35 of the above-described embodiment hits the rear end of the recording material P in the vicinity of the carry-in roller pair 33, the hitting member 35 of the present embodiment has the carry-in roller pair 33. You will hit a position slightly away from. Therefore, the hitting member 35 of the above-described embodiment has a greater effect of hitting the rear end of the curled recording material P than the hitting member 35 of the present embodiment, and more reliably records the rear end of the recording material P. It can be pushed onto the material receiving table 21.

The output shaft 72 is supported by these bearings 91 and 92 so that it can rotate. Here, the side projection 91a on the outer peripheral end of the bearing 91 is engaged with the locking hole 58c of the swing arm 58, so that the swing arm 58 prevents rotation.

At both ends of the output shaft 72 and the swing arm 58
The pressing rollers 37 are attached to the outside of the side plates 58a and 58b so as to rotate integrally with the output shaft 72, respectively. That is, the holding rollers 37 are connected to the output shaft 72.
The pins 93a and 93b fixed to the pins are prevented from rotating.

A torque limiter 77 is mounted between the bearing 91 and the bearing 92 of the output shaft 72. The torque limiter 77 is configured to generate a certain load when the inner ring 77a and the outer ring 77b are rotated in opposite directions. Here, the inner ring 77a is prevented from rotating by a pin 93c fixed to the output shaft 72. On the other hand, the outer ring 77b

As shown in FIG. 6, the holding member 80 according to the present embodiment has a supporting point 81 which is located at an intermediate portion of the holding member 80 and a supporting pin 83 which is fixed to the housing 4.
It is mounted so that it can swing through. The pressing member 80 has both sides bent downward in the drawing with the fulcrum 81 as a boundary, and the bent left portion 84 is a recording material pressing portion that presses the recording material against the recording material receiving table 21. The right portion 85 is a weight portion that generates clockwise turning power in the figure. When the tip of the left portion 84 contacts the tip of the recording material,
In order to prevent the recording material from being damaged, the recording material is bent so that the contact surface with the recording material becomes an arc surface. The right end of the right side portion 85 is bent, and the weight 86 is fixed to the bent portion 85a. Here, the force with which the pressing member 80 (the left portion 84) presses the recording material depends on the fulcrum position of the pressing member 80, the thickness and shape of the pressing member 80, and the like.
By adjusting the weight and the like of the weight 86, it is possible to make the weight 86 an optimum size. The weight 86 may be fixed to the right portion 85 as needed, and may be omitted.

In the holding member 80 having such a structure, the force for holding the recording material does not change with time and the magnitude of the force for holding the recording material can be adjusted. As compared with the pressing member 40 that presses the recording material, the recording material can be pressed with a stable force over a long period of time, and the recording material can be transported more stably.

When the recording material is carried into the recording material receiving table, the rear end of the recording material separated from the nip portion of the carry-in roller pair is pushed into the recording material receiving side by the movable member, and the recording material on the recording material receiving table is also moved. When the recording material is discharged by the recording material moving means, the interval between the recording material receiving table and the recording material receiving table is narrower than that between the carry-in roller pair and the recording material receiving table so that the movable member suppresses the floating of the recording material. It is possible to prevent the recording material from being bent or jammed when the recording material is carried into and out of the material receiving table.

In the intermediate tray of the present invention, the lifting of the recording material on the recording material receiving table is suppressed by a pressing roller, and the pressing roller conveys the leading end of the recording material so as to contact the receiving member. Since the rising of the leading end of the recording material is pressed by the film-shaped pressing member, the recording material can be stored on the recording material receiving table with the leading end of the recording material positioned accurately.

Further, since the recording material processing apparatus of the present invention is provided with the above-described intermediate tray, it is possible to prevent the recording material from being bent or jammed, and to perform accurate processing of the recording material by the recording material processing means. be able to.
