A positioning member 402 provided on the other side, a skew roll 403 that changes the conveying direction of the recording material S after being cut by the X-direction cutting and conveying mechanism 200 from the X direction toward the positioning member 402, and a delivery stage A positioning position detector 404 that detects position information of the recording material S that is provided near the downstream side in the X direction 401 and is conveyed along the positioning member 402, and a conveyance roll 320 of the Y-direction cutting conveyance mechanism 300. ing. Therefore, in this example, the transport roll 320 of the Y-direction cutting and transporting mechanism 300 is also used for the delivery mechanism 400, and is also used with the Y-direction cutting and transporting mechanism 300.

  The delivery stage 401 according to the present embodiment is formed in a substantially plate shape having a predetermined opening in the vertical direction, and is fixed directly by being attached to the post-processing device casing 15 directly or indirectly. Has been. Further, the surface of the delivery stage 401 has a small sliding resistance with the recording material S so that the recording material S can move smoothly. Needless to say, a sufficient opening size is secured in the opening so that the skew roll 403 and the conveyance roll 320 can sandwich and convey the recording material S.

  Further, the positioning member 402 is a member made of a metal or a hard resin that extends linearly along the X direction, and is mounted on the delivery stage 401 along the X direction. The positioning surface 402a orthogonal to the Y direction is positioned so that the cut surface of the recording material S cut by the X-direction cutting and transporting mechanism 200 is positioned on the side facing the X direction (in this example, the same direction is also used in the X direction). It has become.

  Further, as shown in FIGS. 8A and 8B, the skew roll 403 is a pair of roll members that sandwich and convey the recording material S, and is disposed on the upper side. A roll member 403a provided so as to be rotated at a predetermined angle with respect to the transport direction (X direction) of the recording material S cut and transported by the head, and on the lower side so as to face the roll member 403a. And a roll member 403b that is driven and rotated so as to convey the recording material S in the X direction. Further, the upper roll member 403a can be appropriately retracted upward by a solenoid (not shown) or the like. When the two roll members come into contact with each other, a predetermined clamping pressure is applied and the recording material conveyed by the skew roll 403 is conveyed. The sliding surface of the recording material S is positioned on the positioning surface 402a of the positioning member 402 by gradually skewing from the X direction while sliding the S. In this example, the lower roll member 403b of the skew roll 403 is driven. However, the present invention is not limited to this, and the upper roll member 403a may be driven. The member 403a may be rotated along the X direction, and the lower roll member 403b may be provided in an oblique direction intersecting the X direction.

  In the present embodiment, as described above, since the recording material S received in the delivery stage 401 can directly reach the positioning position P2 positioned by the positioning member 402, the skew roll 403 is provided in the delivery stage 401. The recording material S is received at the receiving completion position P1 (described in detail in a second embodiment described later), and has two functions of pressing the recording material S against the positioning position P2. That is, by using such a skew roll 403, the recording material S cut by the X-direction cutting and transporting mechanism 200 and transported to the delivery stage 401 is skewed in the transport stage 401. Thus, the cut surface of the recording material S cut by the positioning surface 402a of the positioning member 402 is positioned. At this time, the position information of the leading edge of the recording material S is detected by the positioning position detector 404, and it is determined that the recording material S has reached a predetermined positioning position P2, and the recording material S is stopped by stopping the skew roll 403. Can be arranged at the positioning position P2.

Further, in the present embodiment, as a mechanism for feeding the recording material S from the positioning position P2 of the delivery stage 401 to the Y-direction cutting and conveying mechanism 300 side by the positioning member 402, the Y-direction cutting and conveying mechanism 300 does not have a dedicated conveying roll. The transport roll 320 has the function. In other words, after the recording roll S is nipped with respect to the recording material S at the positioning position P2, for example, the skew roll 403 is retracted to release the nipping, and then the conveyance roll 320 directly moves to the cutting conveyance section 330. The recording material S is conveyed toward the head.
In the present embodiment, the transport roll 320 is initially within the area of the recording material S at the positioning position P2 so that the recording material S at the positioning position P2 can be nipped and transported by the transport roll 320 of the Y-direction cutting transport mechanism 300. The clamping is released until the recording material S reaches the positioning position P2, so that the positioning of the recording material S is not hindered.

  Next, regarding the control system of the post-processing apparatus 12 in the present embodiment, the delivery control of the recording material S in the delivery mechanism 400 will be mainly described. The control system in the delivery mechanism 400 of the post-processing device 12 is as shown in FIG. In the figure, for example, a position detector 210 and a positioning position detector 404 are connected as inputs of a control device 500 constituted by a computer system such as a CPU, a ROM, and a RAM, while three outputs are output. Drive motors M1 to M3 (270, 410, 370), two solenoids 1, 2 (420, 380) and the like are connected. Needless to say, the control device 500 also controls the second fixing device 100 (see FIG. 3) and the like.

  The drive motor M1 (270) rotates the conveyance roll 220 and the cutting conveyance unit 230 of the X-direction cutting conveyance mechanism 200, and the drive motor M2 (410) rotates the skew roll 403. It has become. Further, the drive motor M3 (370) is configured to rotationally drive the conveyance roll 320 and the cutting conveyance unit 330 of the Y-direction cutting conveyance mechanism 300. On the other hand, the solenoid 1 (420) is a mechanism for sandwiching the skew roll 403, or releasing the sandwich and retracting, and the solenoid 2 (380) sandwiches the transport roll 320 of the Y-direction cutting transport mechanism 300. Or a mechanism for releasing the pinching and retracting. In this example, the drive motors M1 (270) and M2 (410) have different configurations. However, the present invention is not particularly limited thereto. For example, the same drive motor using a drive transmission member such as a gear or a belt. However, it may be possible to use a system such as an actuator or a cam instead of the solenoids 1 and 2 (420 and 380).

Next, a processing process of the image forming apparatus 10 according to the present embodiment will be described.
Now, when print information is input to the image forming apparatus 10 from an input processing apparatus (not shown), an image forming operation is started.
That is, a toner image is formed on the surface of the photoconductive drum 42 of each of the image forming units 41 a to 41 d by a known electrophotographic process, and then each of these color toner images is substantially the same as the photoconductive drum 42 by the primary transfer roll 46. The images are sequentially transferred onto the intermediate transfer belt 50 that circulates and rotates at the same speed (see FIG. 2).
On the other hand, one sheet of recording material S is sent from the first recording material container 30 or the second recording material container 31 to the recording material conveyance path 70, and the fed recording material S is aligned with the rolls 71 and 72. When the sheet is conveyed up to 73, the sheet is temporarily stopped by the positioning roll 73 and then conveyed to the secondary transfer roll 53 at the timing of writing the image on the recording material S. The intermediate transfer belt 50 is transferred to the recording material S. The above multiplexed toner images are collectively transferred.

  Thereafter, when the recording material S is conveyed to the first fixing device 60, the unfixed toner image on the recording material S is fixed by the first fixing device 60. For example, in the case of forming an image on plain paper among the recording materials S, in this example, if the recording material S in the second recording material container 31 is used, the recording material S is sent from the first fixing device 60. The recording material S is discharged and accommodated in the first discharge receiver 76 from the switching gate 74 via the main conveyance path 77 and via the discharge roll 75.

  On the other hand, in the case of forming an image on a photographic coated paper of the recording material S, in this example, if the recording material S in the first recording material container 30 is used, for example, the image is sent from the first fixing device 60. The recorded material S is re-fixed by the second fixing device 100 of the post-processing device 12. That is, the recording material S sent from the first fixing device 60 is sent from the switching gate 74 to the post-processing device 12 through the connection conveyance path 79 and the discharge roll 78. Further, as shown in FIG. 3, after being heat-fixed by the second fixing device 100 and then cooled by the heat sink 130 on the smooth conveying surface of the fixing belt 120, a high-gloss image having a smooth surface is obtained. It is formed. The re-fixed recording material S is peeled off from the fixing belt 120 by the peeling guide members 150 and 151 and sent to the X-direction cutting and conveying mechanism 200 by the feed roll 160.

Next, the recording material S is transported to the X-direction cutting transport mechanism 200, and both side portions (margin portions) of the recording material S in a direction orthogonal to the recording material transport direction (X direction) are cut. At this time, the X-direction cutting / conveying mechanism 200 detects the conveyance position of the recording material S by the position detector 210, conveys the recording material S by the conveyance roll 220, and conveys the recording material S by the cutting / conveying unit 230. At the same time, both side portions (margin portions) of the recording material S in the direction orthogonal to the recording material conveyance direction are cut (see FIG. 4).
The recording material S, which has been removed by cutting both sides of the recording material S, is conveyed to the delivery stage 401 of the delivery mechanism 400 as it is.

  Here, the delivery operation flow (see FIG. 10) of the recording material S in the delivery mechanism 400 performed by the control device 500 (see FIG. 9) will be described. The recording material S that has been cut in the X direction is conveyed to the delivery stage 401 by the X direction cutting and conveying mechanism 200 (steps S1 and S2). Next, the recording material S conveyed to the delivery stage 401 is sandwiched by the skew roll 403 at a predetermined timing from the position detector 210 and is skewed as the skew roll 403 rotates, so that the cut surface is cut. When the positioning member 402 moves so as to follow the positioning surface 402a and the positioning position detector 404 determines that the predetermined positioning position P2 has been reached, the skew roll 403 stops (steps S3 and S4). Thereafter, the transport roll 320 of the Y-direction cutting transport mechanism 300 sandwiches the recording material S, and the sandwiching of the skew roll 403 is released (steps S5 and S6). Then, the transport roll 320 feeds the recording material S from the delivery stage 401, and cutting in the Y direction is performed (steps S7 and S8).

A specific movement of the recording material S in such a delivery operation flow will be described mainly with reference to FIG.
The recording material S transported from the X-direction cutting transport mechanism 200 is sandwiched between the skew rolls 403 as shown in FIG. Since the skew roll 403 sandwiching the recording material S has sliding performance, as the skew roll 403 rotates, the recording material S gradually tilts toward the positioning member 402 side. As shown in b), the leading end of the recording material S comes into contact with the positioning surface 402 a of the positioning member 402. The recording material S having the leading end in contact with the positioning surface 402a moves so that the leading end traces the positioning surface 402a by the sliding performance of the skew roll 403. Then, the cut surface cut by the X-direction cutting / conveying mechanism 200 comes into contact with the positioning surface 402 a, and thereafter, the recording material detection information of the recording material S is skewed at a predetermined timing detected by the positioning position detector 404. The rotation of the roll 403 stops and the recording material S reaches the positioning position P2 as shown in FIG. Thereafter, after the conveyance roll 320 of the Y-direction cutting conveyance mechanism 300 newly comes into contact with the recording material S arranged at the positioning position P2, and the skew feeding roll 403 releases the nipping, the recording material S is nipped and Y By conveying in the direction, the recording material S is fed out from the delivery stage 401 as shown in FIG.

  The recording material S fed from the delivery stage 401 by the transport roll 320 is cut at both side portions (blank portions) of the recording material S along a direction orthogonal to the recording material transport direction (Y direction) of the transport roll 320. Then, the cut recording material S is discharged to the second discharge receiver 16 (see FIG. 4).

  In the present embodiment, the cut surface of the recording material S cut by the X-direction cutting / conveying mechanism 200 is positioned on the positioning surface 402a of the positioning member 402, and further, the Y-direction cutting / conveying mechanism 300 is perpendicular to the positioning surface 402a. Since the conveyance direction (Y direction) is set, the cutting in the Y direction can be performed with the positioning surface 402a as a counter. Therefore, even if the recording material S cut and conveyed by the cutting and conveying unit 230 of the X-direction cutting and conveying mechanism 200 receives a load from the cutting and conveying unit 230 and is bent and conveyed, In the cutting direction in the Y direction by the direction cutting conveyance mechanism 300, the perpendicularity to the X direction is stably maintained, and the guarantee for the perpendicularity of the four corners of the recording material S after the cutting is completed is sufficient. .

In the present embodiment, as the skew roll 403, one roll member is disposed in the direction along the X direction, and the other roll member is disposed obliquely with respect to the X direction. However, the present invention is not limited to this. For example, a roll member capable of driving and rotating disposed obliquely with respect to the X direction on a flat plate may be provided, or a pair of roll members may be disposed obliquely with respect to the X direction. . However, in any case, the recording material S conveyed by the skew roll 403 needs to have a sliding performance so that the moving direction of the recording material S can be easily changed when the leading end contacts the positioning member 402. Needless to say. Therefore, not only the clamping pressure of the skew roll 403 may be adjusted as appropriate, but a release agent coating treatment for ensuring slipping performance may be applied to the roll member surface. Further, a plurality of skew rolls 403 themselves may be provided toward the positioning position detector 404.
Further, in the present embodiment, the positioning position P2 is determined based on information from the positioning position detector 404, but based on the recording material detection information in the position detector 210 on the X-direction cutting and conveying mechanism 200 side. It does not matter even if it is done.

Embodiment 2
The image forming apparatus according to the present embodiment is mounted with a different delivery mechanism 400 from the image forming apparatus according to the first embodiment. Since the configuration of the image forming apparatus itself is substantially the same as that of the first embodiment, the details are omitted here, and the X-direction cutting and conveying mechanism 200, the Y-direction cutting and conveying mechanism 300, and the delivery mechanism 400 are omitted. Only the relationship is shown. In addition, the same reference numerals are given to the same components as those in the first embodiment, and detailed description thereof is omitted here.

  The delivery mechanism 400 in the present embodiment is as follows. That is, as shown in FIG. 12, the positioning member 402 provided for the delivery stage 401 (indicated by a two-dot chain line in the figure) and the recording material S cut by the X-direction cutting and conveying mechanism 200 are placed in the delivery stage 401. The position information of the receiving conveyance roll 405 received in the X direction and the recording material S received in the delivery stage 401 is detected, and the receiving conveyance roll 405 is stopped based on this position information, whereby the recording material S Is received at a predetermined receiving completion position P1 and a receiving position detector 406 and a transport roll 320 ′ of the Y-direction cutting transport mechanism 300. Also in this example, the transport roll 320 ′ is used for both the delivery mechanism 400 and the Y-direction cutting transport mechanism 300.

The receiving and conveying roll 405 in the present embodiment is for nipping and conveying the recording material S, and its conveying direction is in the direction along the X direction. Further, the receiving and conveying roll 405 is retractable so that the nipping can be appropriately released. It has become.
In the present embodiment, in particular, the transport roll 320 ′ of the Y-direction cutting transport mechanism 300 is slidable and capable of reversing operation, unlike the transport roll 320 of the first embodiment. Therefore, the clamping pressure is appropriately selected, or the surface is subjected to a treatment such as a mold release treatment.

  The delivery operation flow (see FIG. 13) of the recording material S in the delivery mechanism 400 having such a configuration will be described. The recording material S that has been cut in the X direction is conveyed to the delivery stage 401 by the X direction cutting and conveying mechanism 200 (steps S11 and S12). Next, the recording material S transported to the delivery stage 401 is sandwiched by the receiving transport roll 405 at a predetermined timing from the position detector 210, moves as it is along the X direction, and positional information of the receiving position detector 406. Is reached to a predetermined acceptance completion position P1 (steps S13, S14). Thereafter, the transport roll 320 ′ of the Y-direction cutting transport mechanism 300 grips the recording material S, and the gripping of the receiving transport roll 405 is released (steps S 15 and S 16). As the transport roll 320 'rotates, the recording material S can be pressed against the positioning member 402, and the transport roll 320' is temporarily stopped at a predetermined timing (step S17). Thereafter, the recording roll S is unwound from the delivery stage 401 by the reverse rotation of the transport roll 320 ', and is cut in the Y direction (steps S18 and S19).

A specific movement of the recording material S in such a delivery operation flow will be described mainly with reference to FIG.
The recording material S conveyed from the X-direction cutting and conveying mechanism 200 is sandwiched between the receiving and conveying rolls 405 at a predetermined timing based on the recording material detection information by the position detector 210 as shown in FIG. Is done. As shown in (b), the recording material S conveyed in the X direction by the receiving conveyance roll 405 is stopped at a predetermined timing based on the recording material detection information detected by the reception position detector 406. By doing so, it is received at the reception completion position P1 of the delivery stage 401. After that, the transport roll 320 ′ on the Y-direction cutting transport mechanism 300 side grips the recording material S at the reception completion position P1, and after the reception transport roll 405 is released, the transport roll as shown in FIG. The recording material S is pressed from the reception completion position P1 toward the positioning position P2 by the rotation of 320 ′ (−Y direction). At this time, the recording material S comes into contact with the positioning surface 402a of the positioning member 402 by the cut surface cut by the X-direction cutting and transporting mechanism 200, and is further pressed by the transport roll 320 ′. Since the transport roll 320 ′ has sliding performance, after the cut surface of the recording material S comes into contact with the positioning surface 402a, the recording material S does not move any more and is disposed at the stable positioning position P2. Will be. And rotation of conveyance roll 320 'stops once at predetermined timing. Next, as shown in (d), the conveyance roll 320 ′ performs a reversing operation, and the recording material S held between the conveyance rolls 320 ′ is fed out from the positioning position P2 in the Y direction.

Therefore, also in the present embodiment, the recording material conveyance direction is stable, and the perpendicularity of the cut recording material S is sufficiently guaranteed.
Needless to say, the transport rolls 320 ′ are spaced apart so as not to interfere with the transport operation of the recording material S by the X-direction cutting transport mechanism 200, and are cut by the X-direction cutting transport mechanism 200. Needless to say, the recording material S is provided at a position where it can contact the recording material surface at the receiving completion position P1.

  Also in the present embodiment, the recording material S in the delivery stage 401 is once arranged at the positioning position P2 by the positioning member 402, and then the recording material S is fed out in a direction orthogonal to the positioning surface 402a. And the perpendicularity formed by the Y direction is stably maintained.

  In the first and second embodiments described above, the transport rolls 320 and 320 ′ of the Y-direction cutting and transporting mechanism 300 are used for feeding the recording material S at the positioning position P2 in the delivery mechanism 400. A dedicated member for feeding out the recording material S at the positioning position P2 from the delivery stage 401 may be used.

  In the first and second embodiments, the X direction and the Y direction are arranged to be orthogonal to each other, and the positioning member 402 is arranged along the X direction. However, the X direction and the Y direction are perpendicular to each other. There is no problem even if it is not arranged in. That is, the arrangement direction of the positioning surface 402a of the positioning member 402 is obliquely arranged in a direction that intersects the X direction at a predetermined angle, and the recording material S cut by the X-direction cutting / conveying mechanism 200 is fed to the skew roll 403 or the conveyance roll. If it is conveyed so as to be slid by the roll 320 ′ and its cut surface is positioned by the positioning surface 402 a, the positioning surface 402 a and the Y direction of the Y direction cutting and conveying mechanism 300 are orthogonal to each other, so that the cutting is performed. The perpendicularity of the recording material S is guaranteed.

Comparison Mode Next, a delivery mechanism shown in FIG. 15 will be described as a comparison mode different from the above-described embodiment.
In the drawing, the delivery mechanism 600 is configured by an X-direction cutting and transporting mechanism 200 and a Y-direction cutting and transporting mechanism 300 as in the present embodiment, and the angle formed by the X and Y directions is a right angle. In the delivery stage 601 in this example, the receiving conveyance roll 602 that conveys the recording material S cut by the X-direction cutting conveyance mechanism 200 in the same direction, and the detection of the recording material S conveyed by the receiving conveyance roll 602 are detected. A receiving position detector 603 for detecting information is provided.

Here, the delivery operation of the recording material S in the delivery mechanism 600 will be described mainly with reference to FIG.
The receiving conveyance roll 602 is for conveying the recording material S along the X direction at the delivery stage 601 as shown in (a), for example, after the recording material S is detected by the position detector 210. The receiving and conveying roll 602 nipping and conveying the recording material S at the predetermined timing. At this time, as indicated by a two-dot chain line in the figure, the cut surface of the recording material S may be conveyed while facing the X direction. However, if it is assumed that the recording material S is conveyed by being inclined by an angle α, the receiving conveyance is performed. The recording material S conveyed by the roll 602 is conveyed in the X direction with the inclination as it is, and stops based on the detection information of the recording material S by the receiving position detector 603 as shown in FIG. Therefore, at this recording material stop position (corresponding to the reception completion position P1 in the above-described embodiment), the recording material S is maintained in a state where it is inclined by the angle α. Next, as shown in (c), since the recording material S is conveyed in the Y direction while the inclination is maintained by the conveying roll 320, the recording material S cut in the Y direction as it is is (d). As shown in FIG. 4, the angles of the four corners are inclined by α from the right angle, and the perpendicularity is not guaranteed.

  That is, in such a delivery mechanism 600, if the recording material S cut by the cutting / conveying section 230 of the X-direction cutting / conveying mechanism 200 is conveyed as it is to the delivery stage 601, it is particularly cut in the Y direction as it is. However, the perpendicularity of the cut recording material S does not matter. However, when the recording material S is cut in the cutting conveyance unit 230, a load is applied to the recording material S. This load is caused by cutting the recording material S while rotating the round blade, and is related to the material and thickness of the recording material S, the blade angle θ, the cutting margin, and the like. Therefore, the cut recording material S may be deviated from the transport direction (X direction). If such a deviation (corresponding to the angle deviation of α in FIG. 16) occurs, the recording material S is cut in the Y direction with the deviation, and at the four corners of the recording material S that has been cut. The perpendicularity will not be maintained.
