Any information about the device is notified based on the setting of the operator.

The notification lamp 44 is provided so as to protrude upward from the upper surface of the apparatus main body 1. The status display lamp 19 is composed of light emitting elements that can emit various colors such as blue, orange, and red. Each color indicates a different state, for example, blue indicates standby or normal operation, orange indicates a state where the sheet S rejected due to a failure exists, red indicates occurrence of various errors, etc. Is possible.

The operation unit 14 and the display unit 15 are electrically connected to the control unit 8. Although not shown, a power button for operating whether power is supplied to the sheet separating and conveying apparatus 100 is provided at the rear of the apparatus main body 1.

The control unit 8 is realized by a CPU, a ROM, a RAM, and the like. The control unit 8 receives the detection results transmitted from the placement sheet detection unit 33, the reject detection unit 43, the defect detection unit, and the angle detection unit. Further, the control unit 8 receives information from the operation unit 14. The control unit 8 stores various programs for separating and conveying the sheet S. The control unit 8 drives the first motor 11, the second motor 12, and the opening / closing member drive motor according to the program based on the detection results from the various detection units and the information from the operation unit 14, and displays necessary for the display unit 15. I do.

The control unit 8 counts the number of sheets S separated and conveyed one by one on the stacking table 21 and displays the counted number on the count display unit 20. Further, when receiving a signal that the count reset button 17 has been pressed by the operator, the control unit 8 resets the cumulative value of the count and sets the display of the count display unit 20 to zero.

Further, the control unit 8 performs control so as to determine whether or not a plurality of sheets S are conveyed in a continuous state based on the detection results of the leading and trailing ends of the sheet S from the sheet end detection unit 67. . At that time, the control unit 8 starts measuring the number of steps of the first motor 11 when a signal indicating that the leading end portion of the sheet S has been detected from the sheet end detection unit 67. Thereafter, the control unit 8 stores the cumulative value of the number of steps of the first motor 11 until a signal indicating that the trailing end of the sheet S has been detected is sent from the sheet end detection unit 67. And the control part 8 compares whether the memorize | stored accumulated value is below the predetermined value according to the magnitude | size of the sheet | seat S set by the operator. When the accumulated value is equal to or less than the predetermined value, the control unit 8 determines that only one sheet S is normally conveyed.

If the cumulative value of the number of steps of the first motor 11 stored in the control unit 8 is larger than the set value, the sheets S are not properly separated and are conveyed in a continuous state with almost no gap. There is a possibility. In this case, since the sheets S are continuous, the length in the transport direction of the sheet S obtained from the detection result of the sheet end detection unit 67 is longer than the actual size of the sheet S. In such a case, the control unit 8 controls the status display lamp 19 to turn on the red light emitting element and perform error display. Then, control is performed to perform an operation when the sheet S to be rejected is generated.

Further, the control unit 8 controls the operations of the sending unit 6 and the conveyance unit 9 so that the sheets S on the stacking table 21 are separated and conveyed at a predetermined timing. The predetermined timing can be selected and set from a plurality of types of patterns by the operator's selection. For example, the control unit 8 controls the conveyance of the sheet S by the conveyance unit 9 based on the detection result of the placed sheet detection unit 33. Further, the control unit 8 controls the conveyance of the sheet S by the conveyance unit 9 based on an operation for starting conveyance of the sheet S by the operator, for example, an operation of pressing the manual operation button 18.

Then, when the defective sheet S to be rejected is generated, the control unit 8 controls to perform the operation selected and set by the operator. For example, when the control unit 8 receives the detection result that the defective sheet S is collected by the reject unit 4 from the reject detection unit 42 according to the setting of the operator, the notification unit 43 collects the sheet to the reject unit 4. And the status display lamp 19 is lit in orange. Thereafter, the control unit 8 may perform control so as to temporarily interrupt the separation and conveyance operation of the sheet S by, for example, disabling the manual operation button 18. Alternatively, when the control unit 8 receives the detection result that the defective sheet S is collected by the reject unit 4 from the reject detection unit 42, the control unit 8 separates and conveys the subsequent sheet S on the stacking unit 2. It may be controlled to drive 63 and rotate the delivery roller 61 to deliver the sheet S to the conveyance path 5. Also, according to the setting of the operator, the control unit 8 receives the detection result from the reject detection unit 42 and then separates and conveys the subsequent sheet S when the operator performs an operation to start conveyance of the sheet S. It is also possible to control to start.

In the state where the control unit 8 grasps that the reject operation by the defect detection has already been performed and the sheet S exists on the reject table 41 based on the detection result from the reject detection unit 42, the separation transport operation of the sheet S is performed. If the subsequent sheet S needs to be rejected due to a failure, the control unit 8 is necessary to transport the subsequent sheet S to be rejected onto the reject table 41. The feeding motor 63 and the first motor 11 are controlled to be driven for a predetermined time set in advance. Then, the control unit 8 sends the sheet S after a predetermined time elapses from the time when the sheet S to be rejected is conveyed on the reject conveyance path 53 and the sheet S to be rejected is placed on the reject table 41. The motor 63 can be driven to control the subsequent sheet S on the stacking table 21 to be separated and conveyed.

At this time, the control unit 8 puts the sending unit 6 into a standby state at the time when the succeeding sheet S to be rejected is placed on the reject table 41, and responds to the pressing of the manual operation button 18 by the operator. Then, control may be performed so that the separation and conveyance of the subsequent sheet S on the stacking table 21 is resumed.

When the trouble of separating and conveying the sheet S occurs continuously for a predetermined number of times such as three times, some problem has occurred in any of the sheet separating and conveying devices 100 such as the conveying path 5 and the sending unit 6. there is a possibility. In this case, it may be necessary to eliminate or adjust the problem by the operator. Therefore, when either the double feed detection unit 66 or the sheet edge detection unit 67 or both of the detection results indicating the abnormality is transmitted continuously for a predetermined number of times, and the control unit 8 receives the detection result, the control unit 8 Changes the status display lamp 19 from orange indicating that a sheet S to be rejected is generated to red indicating the occurrence of an error. Further, the control unit 8 may stop driving the first motor 11 after the conveyance of the sheet S to be rejected by the first and second conveyance rollers 71 and 72 to the rejection table 41 is completed.

Next, the operation of the sheet separating and conveying apparatus 100 according to this embodiment will be described below. When an operator stacks sheets S on the stacking unit 2, presses the power button, and power supply to the sheet separating and conveying apparatus 100 is started, the control unit 8 activates the lifting / lowering unit 24, and on the stacking table 21. The stacking base 21 is raised to a position where the uppermost sheet S among the sheets S comes into contact with the delivery roller 61. Further, the status display lamp 19 is lit in blue. Then, the control unit 8 controls the opening / closing member drive motor, and controls the opening / closing member 76 to be in a tilted posture indicated by a two-dot chain line in FIG.

Thereafter, the operator operates the operation unit 14 to set the size of the sheet S. The size of the sheet S may be automatically set by installing a sheet size detection sensor in the stacking unit 2 instead of the manual setting by the operator.

Further, the operator sets the timing for separating and conveying the sheet S on the stacking table 21, the subsequent countermeasure when the trouble is detected in the conveyed sheet S, the error display, and the like. When the manual setting by the operator is not performed, the subsequent operation may be executed on the assumption that the size and operation state of the initially set general-purpose sheet S are set.

In this way, when the preparation for the sheet S separating and conveying operation is completed, the operator presses the manual operation button 18 in order to start the sheet S separating and conveying operation. Then, the control unit 8 drives the delivery motor 63. As the delivery motor 63 rotates, the delivery roller 61 rotates through the power transmission mechanism. At the same time, the control unit 8 drives the first motor 11. Accordingly, the drive rollers 81 and 82 of the first and second transport rollers 71 and 72 are rotated via the power transmission mechanism, and the driven rollers 91 and 92 are driven to rotate.

The sheet S on the stack 21 is separated from the lower sheet S among the plurality of sheets S on the stack 21 by the delivery roller 61 and the separating member 62, and the rear delivery transport path 54. Sent out. FIG. 5 shows a state where the sheet S is being sent from the delivery conveyance path 54 to the main conveyance path 51.

In FIG. 5, since the upper part 762 of the opening / closing member 76 is inclined at a predetermined angle such as about 20 to 40 degrees from the vertical direction, the sheet S is guided by the guide members 563, 564 and the opening / closing member 76 that constitute the delivery conveyance path 54. Guided and enters the rear main conveyance path 51 from the transmission conveyance path 54. The sheet S is conveyed upward along the main conveyance path 51 by the feeding roller 61 and the second conveyance roller 72 while being guided by the front and rear guide members 56.

Thereafter, the leading end of the sheet S passes through the double feed detection unit 66 installation position and further passes through the sheet end detection unit 67 installation position. Then, the sheet end detection unit 67 transmits to the control unit 8 that the leading end portion Sa of the sheet S has passed. The control unit 8 receives this signal from the sheet end detection unit 67 and starts measuring the number of steps of the first motor 11 in order to determine whether or not the length of the sheet S in the transport direction is appropriate. Further, the double feed detection unit 66 checks whether or not the sheets S are conveyed in a state where a plurality of sheets S are overlapped, and transmits the detection result to the control unit 8.

Thereafter, the leading end portion Sa of the sheet S is sent from the main transport path 51 to the reject transport path 53 by the first and second transport rollers 71 and 72. The control unit 8 stops the driving of the feeding motor 63 when the trailing edge of the sheet S is sent to the feeding conveyance path 54 by the feeding roller 61. Thereafter, the trailing edge of the sheet S leaves the delivery conveyance path 54 and is fed into the main conveyance path 51. Thereafter, the sheet S is further conveyed upward along the main conveyance path 51, the rear end portion Sb of the sheet S passes through the installation position of the double feed detection unit 66, and further passes through the installation position of the sheet end detection unit 67. FIG. 6 shows a state after the rear end portion Sb of the sheet S has passed the installation position of the sheet end detection unit 67. The sheet end detection unit 67 transmits to the control unit 8 that the rear end Sb of the sheet S has been detected.

When the detection result of the trailing edge Sb of the sheet S is received from the sheet edge detection unit 67, the control unit 8 detects the first edge Sa of the sheet S detected by the sheet edge detection unit 67 until the detection of the trailing edge Sb. It is confirmed whether the accumulated value of the number of steps of one motor 11 is equal to or less than a predetermined value corresponding to the size of the sheet S set by the operator. When the accumulated value is equal to or less than a predetermined value corresponding to the set size of the sheet S, the control unit 8 determines that the sheet S is normally separated and conveyed.

As described above, when the length of the sheet S in the conveyance direction is appropriate and the double feed detection unit 66 does not detect the double feed of the sheet S, the control unit 8 drives the opening / closing member drive motor to The swing shaft 77 is rotated counterclockwise in FIG. 4 via the transmission mechanism, and the open / close member 76 is swung so as to be in the upright posture shown by the solid line.

Then, the control unit 8 rotates the first motor 11 in the reverse direction and starts driving the second motor 12. Due to the reverse rotation of the first motor 11, the rotation directions of the first and second transport rollers 71 and 72 are reversed, and the sheet S transported upward in the main transport path 51 starts transporting downward in a switchback manner. Is done. The lower end of the leading sheet S sequentially passes through the installation position of the sheet edge detection unit 67 and the installation position of the double feed detection unit 66 and reaches the installation position of the opening / closing member 76.

At this time, as shown in FIG. 7, the opening / closing member 76 is already in a substantially upright posture, and the opening / closing member 76 is substantially flush with the guide member 561 installed on the front side of the main transport path 51. Therefore, even if the lower end Sb, which is the leading end of the sheet S, is conveyed to the installation position of the opening / closing member 76, it is smoothly moved downward without being obstructed and obstructed by contacting the upper portion 762 of the opening / closing member 76. It is conveyed to.

The opening / closing member 76 is bent slightly toward the rear where the lower portion 761 is on the sheet S conveyance space 57 side, and an upper portion 562a of a guide member 562 installed below the lower portion 761 of the bent opening / closing member 76 is provided. On the contrary, since it is bent slightly forward, the lower end portion of the sheet S comes into contact with the upper part 562a of the guide member 562 installed below the opening / closing member 76 when passing through the installation position of the opening / closing member 76. Thus, the sheet S can be properly conveyed downward without causing a jam.

By driving the second motor 12, the driving rollers 83 to 85 of the third to fifth conveying rollers 73 to 75 rotate, and the belt 311 rotates. The sheet S is transported downward by the third to fifth transport rollers 73 to 75, and the lower end portion that is the leading end of the sheet S enters the mounting transport path 52 curved from the lower part of the main transport path 51. The sheet S is changed in the transport direction to the front and sent to the placement unit 3.

When the sheet S reaches the placement unit 3, the sheet S is conveyed forward by the traveling belt 311. In the conveyance path 5, the sheet S is conveyed while being nipped by the pair of first to fourth conveyance rollers 71 to 74 facing each other, but in the loading conveyance unit 31, the sheet S is released from the nip by the pair of conveyance rollers, The sheet S is conveyed by the force fed forward by the nip between the fifth conveying roller 75 and the belt 311 and the frictional force of the rubber belt 311, and sent to the front mounting table 32.

As described above, in the loading conveyance unit 31, the sheet S is conveyed by the force conveyed by the nip between the fifth conveyance roller 75 and the belt 311 and the frictional force of the belt 311, so that the sheet S is placed on the loading table 32. The operator can quickly take out the sheet S. Further, when the operator takes out the sheet S, the sheet S is not nipped from both sides by a pair of conveying rollers or other pressing members, so that no extra force is required to extract the sheet S, thereby reducing the burden on the operator. Is possible.

The first detection unit 34 detects the leading end of the sheet S, then detects the trailing end of the sheet S, and transmits the detection result to the control unit 8. When the control unit 8 receives the detection result of the rear end portion of the sheet S from the first detection unit 34, the first and second motors 11 start from the time when the rear end portion is received until a predetermined time elapses thereafter. , 12 is continued. Then, the controller 8 stops driving the first and second motors 11 and 12 after the predetermined time has elapsed.

Thus, the control unit 8 continues to drive the first and second motors 11 and 12 until a predetermined time elapses from the time when the detection result of the trailing edge of the sheet S is received from the first detection unit 34. Thus, as shown in FIG. 8, the sheet S sent on the mounting table 32 has the rear end portion Sa of the sheet S positioned in front of the belt roller 313 on the front side of the belt 311. The front portion Sc of the sheet S is placed in a state of protruding further forward than the front end portion 321 of the placement table 32. Thus, the operator can easily grasp the front end portion of the sheet S and remove it from the mounting table 32.

Further, since the placement unit 3 is provided below the stacking unit 2, the operator can easily take out the sheet without reaching a high place.

When the sheet S is removed from the mounting table 32 by the operator, the second detection unit 35 determines that the sheet S on the stacking table 32 has been removed and the sheet S is not on the mounting table 32. 8 is transmitted. When the operator has set to send the subsequent sheet S immediately after the sheet S is removed from the mounting table 32 by the operator, the timing for separating and conveying the subsequent sheet S on the stacking table 21 is controlled. When receiving the detection result from the second detection unit 35, the unit 8 drives the feeding motor 63 and the first motor 11 and starts conveying the subsequent sheet S.

In this manner, by driving the feeding motor 63 and the first motor 11 according to the detection result from the placed sheet detection unit 33, the conveyance of the subsequent sheet S is automatically started even if there is no manual operation by the operator. And can be separated and conveyed more quickly than the sheet S.

Further, even if the sheet S is removed from the mounting table 32 by the operator, the conveyance of the subsequent sheet S is not started immediately, but is kept waiting for sending by the sending unit 6, and the operator presses the manual operation button 18. When the operator has set to start the separation and conveyance of the subsequent sheet S at this time, the control unit 8 causes the feeding motor 63 and the first motor in response to the manual operation button 18 pressed by the operator. 11 is driven to start separation and conveyance of the sheet S by the delivery unit 6. Thus, the sheet S can be conveyed according to the pace of the worker.

When the sheet S is conveyed, when the double feed detection unit 66 detects the double feed of the sheet S or based on the detection result of the sheet end detection unit 67, the first motor 11 measured by the control unit 8. Since the cumulative value of the number of steps is larger than a predetermined value corresponding to the size of the sheet S set by the operator, only one sheet S is not normally conveyed, but a plurality of sheets are conveyed in a continuous state. When it is determined that the control unit 8 is, the control unit 8 executes a reject operation described below.

That is, in the rejecting operation, the control unit 8 first controls the status display lamp 19 to change from blue indicating normal operation to orange indicating that the rejected sheet S has occurred. And the control part 8 continues the rotation in the same rotation direction as it is, without making rotation of the 1st motor 11 into a reverse direction. The control unit 8 stops driving the first motor 11 after a predetermined time has elapsed since the time when the sheet end detection unit 67 detected the trailing end of the sheet S.

Thus, the sheet S is conveyed upward along the main conveyance path 51, reaches the rejection conveyance path 53, and the conveyance direction is changed forward by the curved guide member 56. After the trailing edge of the sheet S has passed the installation position of the sheet edge detection unit 67, the sheet S is conveyed by the first and second conveyance rollers 71 and 72 for a predetermined time, so that the sheet S is transferred to the reject unit 4. Sent. In the reject unit 4, the sheet S placed on the reject table 41 is detected by the reject detection unit 42 and transmitted to the control unit 8.

As described above, since the reject unit 4 that collects the sheet S in which the defect is detected by the defect detection unit is provided, when the sheet S is separated and transported to the placement unit 3, multiple sheets S or a plurality of sheets are fed. When problems such as continuous conveyance occur, the defective sheet S can be collected in the reject unit 4 and the subsequent sheet S can be continuously conveyed. Therefore, it is only necessary to maintain the work without stopping the apparatus every time there is a problem. Thus, the work time can be shortened.

After receiving the detection result of the sheet S on the reject table 41 from the reject detection unit 42, the control unit 8 performs an operation according to the operator's setting. For example, the control unit 8 can notify the collection of the sheet S to the reject unit 4 by the notification unit 43 and can continue the state in which the state display lamp 19 is lit in orange when a failure is detected. Thus, since the notification unit 43 notifies the sheet collection to the reject unit 4 based on the detection result of the reject detection unit 42, it is easy for the operator that the defective sheet S is collected in the reject unit 4. Can grasp. Further, it is possible to prevent the sheet S from being left collected in the reject unit 4.

Thereafter, according to the setting of the operator, the control unit 8 performs control so as to temporarily interrupt the separating and conveying operation of the sheet S by making it impossible to operate the manual operation button 18 or the like. Then, when the sheet S on the reject table 41 is removed by the operator, the separating and conveying operation of the sheet S can be resumed.

Further, when only one sheet S thus rejected is generated by the setting of the operator, the operation is not immediately stopped, and the control unit 8 drives the feeding motor 62 and remains on the stacking table 21. It is possible to continue the separating and conveying operation of the subsequent sheet S.

When all the sheets S on the stacking table 21 are sent out to the transport path 5 by the sending unit 6 and placed on either the placing table 32 or the rejecting table 41, the control unit 8 performs the separating and transporting operation of the sheet S. Stop.

Next, the sheet separating and conveying system 110 provided with a plurality of the sheet separating and conveying apparatuses 100 will be described below. FIG. 9 is a schematic diagram of the sheet separating and conveying system 110. In the sheet separating and conveying system 110, a plurality of sheet separating and conveying apparatuses 101 to 108 are arranged in parallel in the vertical and horizontal directions, and each of the sheet separating and conveying apparatuses 101 to 108 and the personal computer 99 are electrically connected. The connection method between the sheet separating / conveying apparatuses 101 to 108 and the personal computer 99 may be a wired connection using a USB cable or a dedicated cable. The personal computer 99 may be connected to the personal computer 99 inside or outside the company wirelessly using a communication antenna or a communication network. The sheet separating and conveying apparatuses 101 to 108 may be connected.

In the personal computer 99, an operator can set the timing at which the sheets S stacked in the plurality of sheet separating and conveying apparatuses 101 to 108 are separated and conveyed. Based on the information set by the operator, the control device 98 of the personal computer 99 controls the operation of each of the sheet separating and conveying devices 101 to 108.

Further, the control device 98 sets the sheets S stacked on the stacking units 201 to 208 of some of the sheet separating and conveying apparatuses 101 to 108 according to the setting of the operator, when they are not required in one set of sheet separating and conveying operations. It is possible to control the sheet separating and conveying apparatuses 101 to 108 on which necessary sheets S are stacked to be operated and not operating the sheet separating and conveying apparatuses 101 to 108 on which unnecessary sheets S are stacked. In this case, only the necessary sheet S can be easily taken out by not conveying the unnecessary sheet S in one set of sheet separating and conveying operations.

In addition, the control device 98 allows the operator to set all the sheets S placed on the placement units 321 to 328 of the sheet separation and conveyance devices 101 to 108 in one set of sheet separation and conveyance operations according to the setting of the worker. When removed, it can be controlled to perform the next set of sheet separating and conveying operations. In this case, the next set of sheets S can be separated and conveyed more quickly.

In addition, when the order in which the sheets S are arranged in advance for a plurality of sheets S included in a set of sheet separation and conveyance operations is specified in advance by the operator's setting, The operations of the sheet separating and conveying apparatuses 101 to 108 can be controlled. More specifically, the control device 98 can perform control so that each of the sheet separating and conveying devices 101 to 108 is sequentially operated based on the order in which the sheets S are arranged according to the setting of the operator. Further, each of the sheet separating and conveying apparatuses 101 to 108 includes notification units 431 to 438 for notifying the worker that the sheets S to be taken out are the sheet separating and conveying apparatuses 101 to 108 on which the sheet S is to be taken out. 98 can be notified by the notification units 431 to 438 of each sheet separating and conveying apparatus based on the order in which the sheets S are arranged according to the setting of the operator.

FIG. 10 shows an example of a method for setting a plurality of sets of sheet separating and conveying operations. In FIG. 10, the numbers 1 to 8 are assigned to the sheet separating and conveying apparatuses 101 to 108, respectively. For example, the type of a set of sheets S to be sealed in one envelope is assigned according to the direct mail destination. The various sheets S are stacked by the operator on the stacking platforms 211 to 218 of the numbered sheet separating and conveying apparatuses 101 to 108, respectively.

For example, for the first destination in the list shown in FIG. 10, among the sheet separating and conveying apparatuses 101 to 108, the sheet S of the apparatus 3 having the apparatus number and the sheet separating and conveying apparatuses 103 and 105 having the apparatus 5 is not required. The sheets S stacked on the other 1, 2, 4, 6 to 8 sheet separating and conveying apparatuses 101, 102, 104, and 106 to 108 are necessary. In this case, the control device 98 does not operate the sheet separating and conveying devices 103 and 105 and does not separate and convey the sheets S on the stacking tables 213 and 215 of the sheet separating and conveying devices 103 and 105. Then, the control device 98 operates the other sheet separating and conveying apparatuses 101, 102, 104, and 106 to 108 to separate and convey the sheet S from the stacking tables 211, 212, 214, and 216 to 218, and to place the placing tables 321 and 322. The conveyed sheet S is placed on 324, 326 to 328.

In the list shown in FIG. 10, the order in which the sheets S are arranged is specified. The control device 98 sequentially operates the sheet separating and conveying devices 101, 102, 104, and 106 to 108 in the order specified in the list. For example, for the first destination, first, the sheet separating and conveying apparatus 101 of the apparatus 1 in the first order is operated to convey the sheet S on the stacking table 211 to the mounting table 321. The placement sheet detection unit of the device 1 detects that the sheet S has been removed from the placement table 321 by the operator's hand, and the control device 98 receives the detection result. The sheet separating / conveying apparatuses 101 to 108 that need to be operated are sequentially operated based on a preset order of the sheets S, and so on.

After the device 2, the device in the third order is operated. Here, the apparatus 3 adjacent to the apparatus 2 does not require the sheet S, so the apparatus 3 is not operated, and the apparatus 4 in the third order is operated following the apparatus 2. Next to the apparatus 4, the sheet separating and conveying apparatus 106 of the apparatus 6 in the fourth order is operated. Next to the device 6, the device 8 has the fifth order in the list. Therefore, when the sheet S is removed from the mounting table 326 of the sheet separating and conveying apparatus 106 of the apparatus 6, the sheet separating and conveying apparatus 108 of the apparatus 8 that has been skipped by one is operated instead of the apparatus 7 adjacent to the apparatus 6. Subsequently, the sheet separating and conveying apparatus 107 of the sixth apparatus 7 in the order is operated.

As described above, when the order in which the sheets S are arranged in advance is specified for a plurality of sheets S included in one set of sheet separating and conveying operations, the control device 98 can select each sheet separating and conveying apparatus based on the order. Since the operations 101 to 108 are controlled, it is possible to easily understand the order in which the sheets S are taken out, and it is possible to prevent forgetting to remove the sheets S.

Further, the control device 98 notifies the notification units 431 to 438 of the sheet separating and conveying devices 101 to 108 in the order in which the sheets S specified in the list are arranged. Therefore, for example, for the first destination in the list, the sheet separating and conveying apparatuses 101, 102, 104, 106, 108, and 107 are operated in the order of apparatuses 1, 2, 4, 6, 8, and 7. During operation of the apparatus and while the sheet S is being placed on the placing tables 321, 323, 324, 326, 328, and 327, the notification lamps 441 to 448 of the respective apparatuses are turned on. Thus, the operator can instantly grasp where the sheet S to be taken out next is, and can work quickly. Then, the operator can enclose the taken-out plurality of sheets S together in the same order in an envelope. Therefore, even if the order of the sheets S to be sealed is different for each destination, the operator can put the sheets S in the order in which they are taken out, and there is no need to rearrange the sheets S again. , Work efficiently.

The operator removes all the sheets S placed on the placing tables 321, 322, 324, and 326 to 328 of the sheet separating and conveying apparatuses 101, 102, 104, and 106 to 108 for the first destination, and separates and conveys each sheet. The detection result that the sheet S has been removed from the placement tables 321, 322, 324, and 326 to 328 from the placement sheet detection unit of the devices 101 to 108 is transmitted to the control device 98 of the personal computer 99. Then, the control device 98 similarly uses the sheet separating and conveying devices 100 of the required devices 1, 3, 4, 5, 7, and 8 for the set of sheets S to be sealed in the envelope of the next destination. , 103 to 105, 107, and 108 are sequentially operated.

If any one of the sheet separating and conveying apparatuses 101 to 108 has a sheet conveying defect, an appropriate process such as temporarily stopping all the operations according to the operator's setting and redoing the sheet separating operation of the set. I do. That is, for example, when a defect detection is transmitted from the defect detection unit of any of the sheet separating and conveying apparatuses 101 to 108 to the control apparatus 98, the control apparatus 98 temporarily performs the operations of all the sheet separating and conveying apparatuses 101 to 108. Stop. Then, the worker returns the sheet S placed on the placement tables 321 to 328 and the same set of sheets S taken out from the placement tables 321 to 328 to the original loading tables 211 to 218. When the operator performs an operation for redoing the sheet separation / conveying operation of the defective group from the personal computer 99, the control device 98 sequentially performs the sheet separation / conveying operation of the group from the order 1 again.

In this way, the sheet separation and conveyance system 110 is controlled by the control device 98 provided in the personal computer 99 that controls the operation of each of the sheet separation and conveyance devices 101 to 108. Therefore, the separation and conveyance of the sheet S including a plurality of sheets as one set. Operations can be managed collectively.
