  FIG. 3 is an enlarged configuration diagram illustrating an internal configuration example of the paper feeding device 1B, and FIG. 4 is a block diagram illustrating an example of a drive control system of the paper feeding device 1B. FIG. 5 is an explanatory view showing the front and back surfaces of the envelope Pf set in the paper feeding device 1B, and FIG. 6 is a transverse sectional view of the tray 24 of the paper feeding device 1B. 3 to 6 exemplify the sheet feeding device 1B in which the envelope Pf is set, the other sheet feeding devices in which sheets are set can be similarly configured.

  3 and 4, the sheet feeding device 1B includes a bottom plate raising motor 205 that drives the movable table 103 of the tray 124, a pickup motor 201 that drives the pickup roller 107, a sheet feeding motor 202, and a drive system. A transport motor 203. The paper feed motor 202 drives the paper feed belt 109, the reverse roller 110 and the pull-out roller 112. The intermediate conveyance motor 203 drives the first intermediate roller 114 and the second intermediate roller 115.

  In addition, the sheet feeding device 1B has, as detection means, a size detection sensor 130 that detects the size of the envelope Pf, an envelope set sensor 105 that detects the set of the envelope Pf, and a table rise detection sensor that detects the upper limit of the movable table 103. 108, an abutting sensor 111 for skew correction, and a CIS (Contact Image Sensor) reading registration sensor 113 for reading the identification information (for example, barcode) of the envelope.

  As shown in FIG. 4, the configuration of the drive control system of the sheet feeding device 1 </ b> B is configured around a sheet feeding control unit 200. The paper feed controller 200 includes a size detection sensor 130, an envelope set sensor 105, an abutment sensor 111, a table lift sensor 108, a bottom plate home position sensor 106, a registration sensor 113, a pickup motor 201, a paper feed motor 202, and an intermediate transport motor. 203 and a bottom plate raising motor 205 are connected.

  The sheet feeding control unit 200 and the control device 120 serving as a control unit on the image forming apparatus main body side can be configured by, for example, a CPU, a ROM, a RAM, and the like. The CPU expands the program code stored in the ROM to the RAM, and executes the control defined by the program code while using the RAM as a work area and a data buffer. Each part is controlled by executing a program using these CPU, ROM and RAM, various sensors, various motors and the like as hardware resources. The paper feed control unit 200 can communicate with the control device 120 on the main body side of the image forming apparatus 1 via a predetermined communication interface (I / F) 207. Cooperative control of the control device 120 is possible.

  The envelope Pf is set on the movable table 103 and the bottom plate 125 of the tray 124. More specifically, the envelope Pf is set with the front surface Pfa of the envelope Pf facing upward as shown in FIG. 5 and the flap Pfc of the envelope Pf positioned on the side opposite to the paper feeding direction Pfd. Moreover, the width direction orthogonal to the conveyance direction of the envelope Pf is positioned by the side guides 127 and 128 (see FIG. 6). The envelope set is detected by the set filler 102 and the envelope set sensor 105 and transmitted to the control device 120 via the paper feed control unit 200.

  Further, as shown in FIG. 6, the envelope Pf placed on the bottom plate 125 of the tray 124 is sandwiched by a pair of side guides 127 and 128 that can slide in the direction of arrow A along the guide rod 126. , Is set at the center position of the bottom plate 125. Below the bottom plate 125, a size detection sensor 130 (for example, a variable resistance position sensor) that detects the paper size on the bottom plate 125 by detecting the position of the side guide 128 is disposed. The control device 120 or the paper feed control unit 200 compares the value detected by the size detection sensor 130 with, for example, size data stored in advance in the internal memory, whereby the size of the envelope Pf set on the bottom plate 125 is determined. Can be recognized.

  The movable table 103 is configured to be movable up and down (swingable) in the a and b directions by using a bottom plate raising motor 205 as a fulcrum at an end (left end in FIG. 3) on the bottom plate 25 side. When the control device 120 or the paper feed control unit 200 detects that the envelope Pf is set by the set filler 102 and the envelope set sensor 105, the bottom plate raising motor 205 is rotated forward so that the uppermost surface of the bundle of envelopes Pf is the pickup roller. The movable table 103 is raised so as to come into contact with 107. The pickup roller 107 is operated by the pickup motor 201 in the c and d directions shown in FIG. 3 by the cam mechanism, and the envelope discharge side of the movable table 103 is raised and pushed by the upper surface of the envelope Pf on the movable table 103. Go up in direction c. The table rise detection sensor 108 detects the upper limit position of the pickup roller 107, and can thereby detect the upper limit position of the movable table 103. When the operator presses the print start key d on the operation panel 1A, an envelope paper feed signal is transmitted from the control device 120 to the paper feed control unit 200 via the I / F 207, and the pickup roller 107 is rotated forward by the paper feed motor 202. The envelope Pf on the bottom plate 125 is picked up by being driven to rotate. The rotation direction is a direction in which the uppermost envelope Pf is conveyed to the paper feed port.

  The paper feeding belt 109 is driven in the paper feeding direction by the normal rotation of the paper feeding motor 202, and the reverse roller 110 is driven to rotate in the reverse direction to the paper feeding by the normal rotation of the paper feeding motor 202. The envelope is separated and only the uppermost envelope is fed. More specifically, when the reverse roller 110 is in contact with the paper feeding belt 109 at a predetermined pressure and is in direct contact with the paper feeding belt 109 or through one envelope, the reverse roller 110 responds to the rotation of the paper feeding belt 109. Turn counterclockwise. On the other hand, when two or more envelopes Pf enter between the sheet feeding belt 109 and the reverse roller 110, the reverse roller 110 is originally set so that the accompanying force is set lower than the torque of the torque limiter. It rotates in the clockwise direction, which is the driving direction of, and pushes back the excess envelope, preventing double feeding.

  The envelope Pf separated into one sheet by the action of the paper feed belt 109 and the reverse roller 110 is further fed by the paper feed belt 109, the leading end is detected by the abutting sensor 111, and the pull-out roller 112 which is further advanced and stopped. I hit it. Thereafter, the sheet is fed by a predetermined distance from the detection position of the abutting sensor 111, and as a result, the paper feeding motor 202 is stopped while being pressed against the pull-out roller 112 with a predetermined amount of bending, The drive of the paper feeding belt 109 is stopped. At this time, the pickup roller 201 is retreated from the upper surface of the envelope by rotating the pickup motor 201. As a result, the envelope Pf is fed only by the conveying force of the paper feed belt 109, the leading end of the envelope enters the nip of the pair of upper and lower rollers of the pull-out roller 112, and the leading end of the envelope Pf is aligned (skew correction).

  The pull-out roller 112 is a roller that has the skew correction function and conveys the envelope Pf that has been skew-corrected after separation to the first intermediate roller 114, and is driven by the reverse rotation of the paper feed motor 202. At this time (when the paper feed motor 202 is reversely rotated), the pull-out roller 112 and the intermediate roller 114 are driven, but neither the pickup roller 107 nor the paper feed belt 109 is driven.

FIG. 7A is a block diagram showing an example of the internal configuration of the inspection processing apparatus 3, and FIG. 7B shows information on manufacturing specifications for each of the mails manufactured in the encapsulating and sealing apparatus 5. FIG. It is an example of a file. The inspection processing apparatus 3 can inspect envelopes and paper, but the case of inspecting paper will be described.
As shown in FIG. 7A, the inspection processing apparatus 3 is provided with a conveyance path 201 for receiving the sheet output from the image forming apparatus 1, and this conveyance path 201 is connected to the sheet post-processing apparatus 4. It is connected to the exit where paper is delivered. The transport path 201 is provided with a reading device 202 that is a reading unit that reads paper information such as a paper image, color, and outer shape. The reading device 202 is constituted by a CCD, a CIS, or the like, and the CCD and the CIS are arranged facing the upper and lower sides of the conveyance path 201 so that both sides of the sheet can be read. Note that the reading width in the direction orthogonal to the paper transport direction is set to be equal to or larger than the maximum paper passing width so that the outer shape of the paper can be read.

  A branch path 203 is provided on the downstream side of the conveyance path 201 in the sheet conveyance direction. The branch path 203 is for branching an abnormal sheet from the conveyance path 201 so as not to be conveyed to the sheet post-processing unit 4. When it is determined that the paper is abnormal by reading by the reading device 202 described later, a branch claw (not shown) is switched to the branch path 203 side, and the abnormal paper is guided to the branch path 203 so as to be exposed to the outside of the inspection processing apparatus 3. It is conveyed to an inspection tray 204 which is an abnormal paper storage unit provided. In addition, the conveyance path 207 is provided in the middle of the branch path 203. When a branch claw (not shown) is switched to the conveyance path 207 side, normal paper is temporarily stored in the buffer tray 205 which is a normal paper storage unit. It is designed to be conveyed.

  The buffer tray 205 is provided with a paper re-feeding means 206 so that the paper can be re-fed and conveyed to a re-feed path 206 a provided so as to join the conveyance path 201. More specifically, the sheet guided to the buffer tray 205 by the transport path 207 is transported to the transport path 201 by the refeed unit 206 through the refeed path 206a and passes through the reading device 202 again. .

  Further, the storage device 208 configured by a hard disk or the like for storing image data of the output paper read by the reading device 202, the read image is compared with reference data, and the abnormality detection means together with the reading device 202 A comparison device 209 is provided. Further, a CPU 210 is provided as a control unit for controlling the sequence control and data handling of the entire inspection processing apparatus, and the control of the image forming apparatus 1 and the sheet post-processing 4. The inspection processing device 3 calculates the similarity between the image data from the reading device 202 and the image data stored in the storage device 208, and determines the quality (abnormality) of the output paper based on the similarity. Yes. Next, an example of a method for calculating the similarity will be described.

  FIG. 8A shows a pattern of image data read by the reading device 202 of the inspection processing apparatus 3, and FIG. 8B shows a pattern of image data stored in the storage device 208. Each pattern is expressed as B (i, j) and P (i, j). B (i, j) and P (i, j) take a value of “1” for black pixels and “0” for white pixels. Also, assuming that the center-of-gravity coordinates of B (i, j) and P (i, j) are (ibc, jbc) and (ipc, jpc), the similarity COR between them is expressed by the following equation.

  The above equation 1 represents the Hamming distance when the centers of gravity of the patterns B (i, j) and P (i, j) are aligned. Also, the greater the COR value, the greater the similarity between the two. When the similarity COR is calculated by the above calculation, the preset threshold value Th and COR are compared. That is, when COR> Th, the read image data is almost the same as the image data in the storage device, and is determined to be a non-defective product. On the other hand, when COR <Th, the similarity between the two image data is low, and it is determined that the product is abnormal (abnormal paper). Note that the accuracy of determination can be changed by changing the value of the threshold Th. It is also possible to provide a more flexible inspection function by changing the value of the threshold Th according to the type of image data to be inspected. When it is determined that the product is abnormal (abnormal paper) based on the similarity thus calculated, the inspection processing device 3 removes the paper determined to be abnormal and removes the CPU (control device 120) from the image forming apparatus 1. A command instructing to form an image formed on the abnormal sheet on another substitute sheet is transmitted.

The CPU 210 reads paper information output from the image forming apparatus 1 by using the reading device 202, for example, image information and paper shape. The read information is compared with the original data stored in the storage device 208 in advance by the comparison device 209. If the comparison result is OK, the paper passes through the conveyance path 201 as it is and is sent to the paper post-processing device 4. It is done. This operation is sequentially repeated.
On the other hand, if it is determined as abnormal as a result of the comparison by the comparison device 209, the paper determined as abnormal is discharged to the inspection tray 204. The inspection tray 204 is exposed to the outside of the inspection apparatus, so that the user can visually recognize the discharged paper, and the user can easily understand what kind of abnormality the paper is. it can.

  By the way, at this time, the sheet conveyed to the inspection processing apparatus 3 next, that is, the sheet that has already passed through the fixing device, the sheet during image formation, or the sheet feeding apparatus 1B is fed into the image forming apparatus. There may be several sheets in progress such as paper. Therefore, when an abnormal sheet occurs, the CPU 210 determines whether or not there is a sheet for which an image is being formed (hereinafter referred to as an in-process sheet) in the image forming apparatus through communication with the control device 120 of the image forming apparatus 1. When it is determined that there is a work-in-process sheet, an instruction is sent to the control device 120 of the image forming apparatus 1 to perform the process from image formation to fixing for the work-in-process sheet, and temporarily stop the subsequent operation. Further, the paper after the work-in-process paper is fed as a substitute paper for the abnormal paper, an instruction is given to form an image formed on the abnormal paper on the substitute paper, and an image is sent via the control device 120 of the image forming apparatus 1. Control the forming part. As a result, the paper in progress is thereafter guided to the inspection processing device 3 with the image fixed, and the paper information is read by the reading device 202. As a result of the comparison by the comparison device 209, if the inspection is OK, the in-process sheets are guided to the buffer tray 205 and sequentially stacked. If it is determined that the result of the comparison is abnormal, the abnormal paper is discharged to the inspection tray 204.

  On the other hand, after the work-in-process sheet is stacked on the buffer tray 205 (or the inspection tray 204) in this way, in other words, after the work-in-process sheet in the image forming apparatus is exhausted, the substitute sheet on which the image is formed is transferred to the inspection processing apparatus 3. It is conveyed and passes through the reading device 202. Then, the information is read by the reading device 202, and if the inspection is OK, the information is guided to the paper post-processing device 4. As a result of the comparison, if it is determined that the substitute sheet is abnormal, the abnormal sheet is discharged to the inspection tray 204, and the control apparatus 120 of the image forming apparatus 1 is instructed to output again. Then, after the substitute sheet is guided to the sheet processing apparatus 4 in this way, a sheet to be received next, that is, a sheet to be inspected is determined. Here, when the work paper is stacked on the buffer tray 205, the work paper is sequentially re-fed from the buffer tray 205 by the re-feed unit 206, passes through the conveyance path 201, and is sent to the paper post-processing device 4. Guided. At this time, the sheet information is read again by the reading device 202, and this time, it is checked whether there is any abnormality in the shape of the sheet such as double feeding or folding. If the inspection of the re-feed sheet is OK, The re-feed paper is guided to the paper post-processing device 4 and the control device 120 of the image forming apparatus main body 1 is instructed to perform the remaining jobs. As a result of the comparison, when it is determined that the re-feed paper is abnormal, the abnormal paper is discharged to the inspection tray 204 and the output is instructed to the control device 120 of the image forming apparatus 1 again. The paper (replacement paper) re-output according to this instruction is then inspected after passing through the reading device 202 as described above.

  As described above, the abnormal paper is discharged to the inspection tray 204 and the non-defective product is stored in the buffer tray 205 without being discarded, and an image formed on the abnormal paper is formed on the substitute paper and re-output. By refeeding the paper stored in the tray 205, even if an abnormal paper is generated, it is possible to recover the abnormal paper automatically removed without stopping the image forming apparatus 1. As a result, it is not necessary for the user to reside in front of the image forming apparatus 1, and productivity is improved. Further, with this configuration, there is no paper to be discarded other than the abnormal paper, so there is no waste, and no abnormal paper is conveyed to the paper post-processing device 4. It can be assured that the bound booklet is a non-defective product.

Next, the inspection means in the name identification inspection mode of the inspection processing apparatus 3 will be described.
A number identifying a group to be enclosed is printed on the sheet conveyed from the image forming apparatus 1. In a plurality of types of paper, the paper enclosed in a specific envelope may be all types of paper, but usually only the paper selected from the plurality of types is sealed. For example, when there are six types of sheets A to F, A, B, C, and D are selected and sealed in the envelope 1, and A, B, C, E, and F are selected in the envelope 2 Then, A, E, and F are selected and sealed in the envelope 3, and so on. At this time, the number “12345” specifying the group to be enclosed is printed on the sheets A, B, C, and D enclosed in the envelope Pf1, and the sheets A, B, C, E, and F enclosed in the envelope Pf2 are printed on the sheets A, B, C, E, and F. The number “12346” specifying the group to be enclosed is printed, the number “12347” specifying the group to be enclosed is printed on the sheets A, E, and F enclosed in the envelope Pf3, and so on. . The number that identifies the group to be enclosed is not limited to ordinary numbers, and includes OCR characters, bar codes, two-dimensional codes, and the like. The printing of this number can be performed off-line at a time before enclosing and sealing. At that time, it is handled so that the order is not changed, and the sheet on which the number is printed is set in the enclosing sealing device 5. Moreover, the printing of this number can be printed inline in the enclosing sealing device 5. For example, an ink jet printer or the like may be provided in the paper supply unit, and printing may be performed simultaneously during the paper supply process. As a result, inspection can be performed even when paper from the inserter (supply unit) is fed. This number is individual information, and printing of such individual information can be performed based on information obtained by referring to the enclosure number table 213 or the like.

  The manufacturing specification file 212 shown in FIG. 7B is generated based on customer (destination) information, specification information, etc. in a higher-level computer system, and is downloaded to the content inspection system for use.

  The number that identifies the group to be enclosed, the destination (address, name, etc.), the type of contents to be enclosed, etc., are different parts for each email. A file of information necessary for manufacturing such individual mails is a manufacturing specification file 212. An enclosure number table 213 exists in the manufacturing specification file 212.

  When individual information is printed in the process of supplying paper, the individual information to be printed is read from the enclosure number table 213. Further, when the process of checking whether or not the paper is appropriate is performed, information on the appropriate paper is read from the enclosed number table 213 and compared with the reading number read by the number reading device 211. The enclosure number table 213 is stored in a memory, and is a table in which numbers are associated with the types of sheets belonging to the enclosed group specified by the numbers.

  Before the inspection unit compares the reading numbers read by the number reading device 211, the number is predicted. For this purpose, first, the number is read with reference to the enclosure number table 213. Here, for example, the number is read as a number that is larger (or smaller) than the number read last time, has the smallest difference from the number read last time, and exists in the enclosure number table 213. Then, the number is set as a prediction number. By performing such reading, it is not always necessary to set the numbers in the enclosure number table 213 as serial numbers. Even if the number becomes discontinuous when the mail to be manufactured is selected in editing the enclosing number table 213, the number can be used as it is. The reading number output by the number reading device 211 is compared with the predicted number that is the predicted number, and a number comparison result indicating whether or not they match is output. Thereafter, it is determined whether or not it is appropriate based on the number comparison result, and the determination result is output.

FIG. 9 is a configuration diagram illustrating an example of an internal configuration of the sheet post-processing apparatus 4. In the following description with reference to FIG. 9, the saddle stitching operation for performing the saddle stitching process on the paper P will be mainly described.
The paper sorted by the branch claw 135 and the branch claw 136 from the conveyance path A is guided to the conveyance path B, and is discharged to the processing tray T by the conveyance roller 137, the conveyance roller 138, the conveyance roller 139, and the staple paper discharge roller 140. The In the processing tray T, the same operation is performed until the sheets sequentially discharged by the paper discharge roller 140 are aligned and immediately before stapling (saddle stitching). After the sheet bundle is temporarily aligned on the processing tray T, the leading end of the sheet bundle is sandwiched between the discharge roller 143 and the pressure roller 141a attached to the end of the branch guide plate 141, and the branch guide plate 141 and the movable guide 142 is rotated again by the discharge claw 145 and the discharge roller 143 so as to pass the path guided to the processing tray C by rotating. The discharge roller 143 is provided on the drive shaft of the discharge belt 144 and is driven in synchronization with the discharge belt 144.

  Thereafter, the sheet bundle is conveyed by the discharge claw 145 until the rear end thereof passes the discharge roller 143, and further conveyed by the upper bundle conveyance roller 146 and the lower bundle conveyance roller 147. At that time, the stop position of the movable rear end fence 148 differs depending on the size of each sheet bundle in the transport direction, and is waiting. When the front end of the sheet bundle P ′ contacts and is stuck on the movable rear end fence 148 that is waiting, the pressure of the lower bundle conveying roller 147 is released, and the rear end tapping claw 149 strikes the rear end of the sheet bundle. Final alignment in the transport direction. That is, an alignment operation is performed in which the width direction of the sheet bundle P ′ is aligned by the saddle stitching jogger fences 150 and 151, and the conveyance direction of the sheet bundle P ′ is aligned by the movable rear end fence 148 and the rear end tapping claw 149. Then, the center of the sheet bundle P ′ is bound by the saddle stitch stapler S. Here, the movable rear end fence 148 is positioned by pulse control from the movable rear end fence HP (home position) sensor 152, and the rear end hitting claw 151 is controlled by pulse control from the rear end hitting claw HP (home position) sensor 153. It is positioned. The saddle-stitched sheet bundle P ′ is conveyed upward along with the movement of the movable rear end fence 148 while the pressurization of the lower bundle conveying roller 147 is released, and thereafter the vicinity of the stapled staple portion is in a substantially perpendicular direction. Are pushed by the folding plate 154 and guided to the nip of the opposing folding roller 155. The folding roller 155 that has been rotated in advance folds the center of the sheet bundle P ′ by conveying the sheet bundle P ′ under pressure, and conveys the sheet bundle P ′ as it is to the downstream subsequent machine.

And FIG. The pressure roller 156 that performs the folding process on the fold line is downstream in the transport direction of the sheet bundle (sheet bundle) P ″ after the center folding process that is transported through the transport path 157 by the rotation of the first folding roller 155. It is provided at a position close to the side. The pressure roller 156 is provided by a roller moving mechanism 158 so as to be movable in a direction orthogonal to the sheet bundle conveying direction (sheet conveying direction) (a direction perpendicular to the drawing sheet). As shown in FIG. 10A, the sheet bundle P ″ is folded by the first folding roller 155 and then conveyed in the direction of the arrow as it is. Only stops and stops at the position shown in FIG. At this time, the stop position of the fold portion Pc, which is the leading end portion of the sheet bundle P ″, is on the movement locus of the pressure roller 156 moved by the roller moving mechanism 158. The pressure roller 156 moves in the direction (perpendicular to the paper surface in the drawing) perpendicular to the sheet bundle conveyance direction (sheet conveyance direction) at the position shown in FIG. The fold portion Pc is further folded (pressurized), and the fold is strengthened. After the additional folding process in which the folds are strengthened is completed, the sheet bundle P ″ is conveyed in the direction of the arrow in FIG. 10B by the conveying roller 160 and is conveyed toward the downstream subsequent machine. On the other hand, when the post-processing is not necessary in the downstream succeeding machine, the sheet bundle P ″ after the additional folding process is conveyed in the paper discharge direction.

In the enclosing sealing device 5 of FIG. 11, the envelope is conveyed as follows. The envelope set in the paper feeding apparatus 1B is fed into the image forming apparatus 1, and after an address is formed as an image, the envelope is conveyed to the sealing and sealing apparatus 5 via the inspection processing apparatus 3 and the paper post-processing apparatus 4. . The envelope is first carried into the entrance conveyance path 9. After the envelope is detected by the inlet sensor 8A, the conveyance rollers are driven to start conveyance of the envelope. The branch claw 11 has moved to a position leading to the upper conveyance path 12, and the envelope is conveyed to the upper conveyance path 12. Further, the branch claw 13 has moved to a position leading to the envelope conveyance path 14, and the envelope is conveyed to the envelope conveyance path 14. The flaps of the envelope are held in a state where the chuck roller pair 23 is bitten, and waiting for the paper as the enclosed material to be enclosed. At this time, the swing roller pair 25 is retracted in the direction of the arrow and is in a position not in contact with the envelope.

<Processing and transportation of inclusions>
Moreover, in the enclosure sealing apparatus 5 of FIG. 11, the enclosure thing enclosed with an envelope is processed as follows, and is conveyed. After the original is read by the ADF 2, the corresponding paper is fed into the image forming apparatus 1 from the paper feeding device 1 </ b> B, and after the image is formed, the sealed sealing is performed via the inspection processing device 3 and the paper post-processing device 4. It is conveyed to the device 5. When the inclusion is a single sheet or a sheet bundle that has been subjected to the edge binding process, it is carried into the entrance conveyance path 9. After the inclusion is detected by the inlet sensor 8A, each conveyance roller is driven to start conveyance of the inclusion. When the enclosed material is a booklet that has undergone saddle stitching processing by the paper post-processing device 4, it is carried into the entrance conveyance path 10. In this case, after the inclusion is detected by the inlet sensor 8B, each conveyance roller is driven to start conveyance of the inclusion, and the branching claw 11 is moved to a position leading to the upper conveyance path 12. Is transported to the upper transport path 12, and then follows the same transport path as a single sheet or a bundle of sheets subjected to edge binding processing. After the inclusion is conveyed to the upper conveyance path 12, the branching claw 13 is further moved to a position leading to the inclusion conveyance path 15, and the inclusion is conveyed to the inclusion conveyance path 15. The inclusion passes through the inclusion discharge sensor 16 and is discharged to the intermediate tray 18. After being discharged to the intermediate tray 18, the return roller 17 moves to a position where it comes into contact with the intermediate tray 18, and conveys the filled material toward the rear end stopper 21. After the completion of conveyance, the alignment operation is performed by the side jogger pair 20. The same operation is repeated until all the inclusions to be enclosed in the envelope are prepared.

<Encapsulation process>
Moreover, in the enclosure sealing apparatus 5 of FIG. 11, enclosure of the inclusion in the envelope is performed as follows. After all the inclusions are stacked on the intermediate tray 18, the rear end stopper 21 is retracted in the direction of the arrow. After retraction, the tip stopper 19 starts to move in the direction of the arrow, and the bundle of inclusions is conveyed into the pack unit 22. After the transport to the pack unit 22 is completed, the pack unit 22 moves in the direction of the arrow, and is transported and sealed by the transport roller in the pack unit 22 to the envelope in the chuck roller pair 23 part. After completing the sealing, the swing roller pair 25 moves in the direction opposite to the arrow, and starts transporting the envelope to the transport path 26.

  In the image forming system, the user selects a paper feed size and post-processing means on the operation panel 1A with a display device before passing the paper as a normal operation, and then starts a job. In the image forming system according to the present embodiment, a new category of inspection and an inspection mode button for whether or not to perform inspection are provided in the post-processing means determination unit. As inspection types, quality inspection and name identification inspection are set.

  FIG. 12 is an explanatory diagram illustrating an example of an inspection setting screen on the operation panel 1A. This inspection setting screen functions as inspection processing selection means. Further, in the example of the setting screen of FIG. 12, when the “inspection” tab 901 is selected and the “inspection mode” button 902 is pressed when the enclosing job mode is selected on the enclosing setting screen (not shown), the “quality inspection” "Display 903, and quality inspection is set.

Here, a control flow until the inspection mode is determined in the image forming system of the present embodiment will be described.
FIG. 13 is a flowchart for explaining an example of a procedure for automatically setting the inspection mode. In this example, there are two cases as a premise: inspection is performed (inspection mode) and inspection is not performed (non-inspection mode).
In FIG. 13, the user selects whether or not to inspect at the time of various settings prior to passing paper (step S1). When the inspection is not performed, the inspection mode button 902 is not pressed (No in Step S1), thereby entering the non-inspection mode in which the inspection is not performed (Step S2). As an operation performed in the non-inspection mode, the sheet conveyed to the inspection processing apparatus 3 is directly transferred to the downstream machine. On the other hand, when the inspection is performed, the inspection mode button 902 is pressed (Yes in step S1), and when the user selects the job content to be executed, the inspection type is automatically selected. That is, when the enclosing and sealing device 5 is connected and the enclosing job mode is selected, the name collation inspection is automatically selected (Yes in step S3, step S4). On the other hand, when a mode other than the enclosed job mode is selected, quality inspection is automatically selected (No in step S3, step S5). The name identification inspection inspects whether the conveyed paper is not printed excessively or whether the paper is missing. On the other hand, the quality inspection inspects the image and shape of the conveyed paper. Basically, the type of inspection is automatically selected, but can be changed so that it can be manually selected by an initial setting unit (not shown) of the user.

Next, an example of a specific example when inspection by the inspection processing apparatus 3 is rejected (hereinafter referred to as “NG”) will be described.
First, a case where the inspection is NG during the quality inspection will be described. The sheet information as the comparison source stored in the storage device 208 includes sheet outline information, image position, and the like. Then, the comparison device 209 divides these pieces of information into grid-like elements and performs comparison for each corresponding element. When the CPU 210 recognizes the difference and recognizes the difference, the CPU 210 sends a signal for switching the paper conveyance path, discharges the paper to the inspection tray 204, and outputs a substitute paper on which the same image as the abnormal paper is formed. The controller 120 of the image forming apparatus 1 is instructed. Thereafter, the inspection processing apparatus 3 performs the same operation as described above.

  Next, the case where the inspection is NG during the name identification inspection will be described. The sheet reading number read by the number reading device 211 is compared with the number predicted from the number read with reference to the enclosure number table 213, and a number comparison result indicating whether or not they match is output. Based on the number comparison result, it is determined whether or not it is appropriate, and the determination result is output. If the numbers do not match and if the same number is duplicated, it is determined that there is excessive printing, and the paper is discharged to the inspection tray 204. Otherwise, if the numbers do not match, it is determined that a missing sheet has occurred, and the subsequent sheet is transported to the normal buffer tray 205 and recovery printing of the missing sheet is performed as in the case of quality inspection.

  Here, depending on the abnormal state of inspection, it may not be OK even if the image forming apparatus 1 re-outputs the image many times. Therefore, it is desirable to set a limit on the number of automatic recovery operations. FIG. 14 is a flowchart showing the inspection processing procedure. FIG. 15 is an explanatory diagram showing an example of the inspection NG result history list screen of the operation panel 1A.

  By providing a limit on the number of times of automatic recovery operation, the inspection processing apparatus 3 instructs the control device 120 of the image forming apparatus 1 to output again and counts the number of NGs until the inspection result becomes OK. When the number of times of NG reaches the set number of times, a stop command is output to the control device 120 of the image forming apparatus 1, and further, the operation panel 1A displays that the job has been stopped due to repeated NG, and the image forming apparatus. Inform the user to check 1. Further, these NG histories can be confirmed later as shown in FIG. As an example of the NG factor shown in FIG. 15, an example of recognizing the edge of the paper, skewing, and color is given. In addition to this, the paper density, color misalignment, dirt, punch hole position, tab position, etc. You can also recognize and compare various information about.

Here, when the number of NG inspection results exceeds the number of recovery settings, the processing differs depending on the selected inspection mode and the content of the NG. Therefore, next, processing for each selected inspection mode will be described with reference to the flowchart of FIG.
In FIG. 14, when the paper inspection result is NG (Yes in step S10), it is determined whether or not the excessive printing of the paper is the cause in the name verification inspection mode (step S11). In case of NG due to excessive printing of paper in the name collation inspection mode, recovery printing is not performed, and the currently executed job is continued without stopping (Yes in step S11). That is, excess printing paper is discharged to the inspection tray 204, and subsequent paper is conveyed to the downstream machine to continue the processing (steps S12 and S13). As a result, it is not treated as an NG job. Although it is arbitrarily possible to display NG of overprinting on the operation panel 1A of the image forming apparatus 1, when NG is displayed, it is also notified that the job has been completed normally as a result. If the inspection result is OK (No in step S10), the subsequent sheet is naturally conveyed to the downstream machine and the process is continued (step S13).

  When the inspection result is other than overprinting of the paper in the name identification inspection mode (No in step S11), there are a case of paper missing printing in the name identification inspection mode and a case of quality inspection. In any case, first, it is compared whether or not the number of NG inspection results is equal to or less than the recovery set number (step S14). When the number of NG inspection results is equal to or less than the number of recovery settings (Yes in step S14), a recovery process is performed (step S15). That is, in the case of paper missing printing in the name collation inspection mode, the subsequent paper is conveyed to the normal buffer tray 205 and recovery printing of the missing paper is performed. On the other hand, in the quality inspection mode, the abnormal paper is discharged to the inspection tray 204 and recovery printing is performed to output a substitute paper on which the same image as the abnormal paper is formed.

On the other hand, when the number of NG inspection results is greater than the number of recovery settings (No in step S14), the processing is different between the case of missing paper printing in the name identification inspection mode and the case of quality inspection mode. For this reason, it is determined whether or not the sheet is missing printing in the name collation inspection mode (step S16).
In the case of paper missing printing in the name collation inspection mode (Yes in step S16), the subsequent paper is transported without interrupting the job being executed, the sealing process is performed, and then the sealing process is not performed (step S17). Further, the target sheet for the NG job is displayed on the operation panel 1A of the image forming apparatus 1 as the “inspection NG result history list” screen 904 as shown in FIG. 15 (step S18). By displaying an NG job on the operation panel 1A, the user can easily find an envelope in which a sheet is missing from an unsealed envelope, and print the missing sheet later and enclose it in the corresponding envelope. This makes it possible to use an NG envelope. In addition, since the job being executed is not interrupted even if it is NG, an effect of improving productivity can be expected.
In the case of No in the above step S16, that is, in the case of the name collation inspection mode, it is determined that the quality inspection mode is selected and the job being executed is interrupted (step S19). In this case as well, the target sheet of the NG job is displayed as the “inspection NG result history list” screen 904 on the operation panel 1A of the image forming apparatus 1 as shown in FIG. 15 (step S18).

An accurate encapsulation process is performed.
Further, according to the present embodiment, the control device 120 controls to execute the quality inspection processing as the second inspection processing in the case of an image forming job not accompanied by the sealing processing by the sealing device 5. As a result, in the case of an image forming job that does not involve the enclosing process by the enclosing / sealing device 5, the quality inspection process of the paper P sealed in the envelope Pf is automatically executed even if the user does not manually select the quality inspection process. Thus, the quality of the image formed on the paper P is maintained.
Further, according to the present embodiment, the inspection setting screen is displayed on the operation display screen 900 of the operation panel 1A as inspection processing selection means for the user to select one of the plurality of types of inspection processing.

Therefore, the job is stopped every time the abnormality or missing of the paper P is detected. Compared with, workability and productivity are improved.
Further, according to the present embodiment, when the inspection processing apparatus 3 detects a missing sheet P, the control device 120 re-executes image formation by the image forming apparatus 1 for the missing sheet, and the sheet P is missing. When the number of times of detection exceeds a predetermined number of times set in advance, control is performed so that sheets other than missing sheets are sealed in the envelope Pf without interrupting the job being executed. As a result, the number of re-execution of image formation is suppressed to a predetermined number or less, and the job being executed is not interrupted, so that a decrease in productivity can be prevented. In this case, it is preferable that the inspection result in which the missing sheet is detected is displayed on the display means, and the envelope in which the missing sheet is detected is not sealed. Thus, after the job is completed, the user can individually form an image on the missing sheet and enclose it in an envelope based on the inspection result displayed on the display means. In addition, since the sealing is not performed, it is possible to easily find the envelope in which the missing sheet is detected, and it is easy to additionally seal the missing image-formed sheet in the envelope.
