Description

The present invention relates to a sheet transfer device for transporting a sheet to which a sticky note is attached.

In most cases, only a part of the sticky note attached to the sheet is attached to the sheet with a small adhesive force so that it can be easily peeled off later. Therefore, if the sticky note comes into contact with any of the transport rollers during the transport of the sheet to which the sticky note is attached, the sheet is likely to be peeled off or bent due to the rotational driving force of the transport roller. In particular, when the sticky note is peeled off from the sheet, the sticky note remains on the transport path of the sheet, and the sticky note remaining on the transport path comes into contact with another sheet to be transported thereafter, which hinders the transport of the sheet. This may cause sheet clogging (jam).

In Patent Document 1, when it is predicted that either the sheet to which the sticky note is attached and the transport roller will be in contact with each other, the sticky note is controlled so as not to transport the sheet or to interrupt the transport control. The paper and the transport roller are kept out of contact with each other to prevent the sticky notes from peeling off.

JP-A-2016-222451

By the method described in Patent Document 1, it is possible to prevent the sticky note attached to the sheet from coming into contact with the transport roller.

However, if the sheets judged to be in contact are not transported or the transport control is interrupted, not only the transportability is deteriorated, but also when the interruption during transportation occurs, it is necessary to remove the interrupted sheet. This will increase the burden on the user.

Therefore, an object of the present invention is to avoid contact between the sticky note and the transporting means, and to transport the sheet without stopping or interrupting the transport.

In order to achieve the above object, the sheet transport device according to the present invention has a sheet transport means for transporting sheets in a predetermined transport direction, and at least one of a sheet transported by the sheet transport means and the sheet transport means is the other. On the other hand, a moving means for relatively moving in the width direction orthogonal to the conveying direction, a sticky note position recognizing means for recognizing the position of the sticky note attached to the sheet conveyed by the sheet conveying means, and the like. A duplication recognition means for recognizing whether or not the sticky note recognized by the sticky note position recognizing means and the sheet transporting means overlap at least a part in the width direction, and the sticky note and the sheet by the duplication recognition means. When it is recognized that the transport means overlaps, the movement is such that at least one of the sheet and the sheet transport means is moved relative to the other so that the sticky note and the sheet transport means do not overlap. It includes a control means for controlling the means.

According to the present invention, when it is determined that the sticky note attached to the sheet and the sheet conveying means such as the conveying roller overlap, at least one of the sheet and the sheet conveying means is in the width direction orthogonal to the conveying direction with respect to the other. By moving the sticky note relative to, it is possible to transport the sheet while avoiding contact between the sticky note and the sheet transporting means, and the sheet with the sticky note attached can be moved without stopping or interrupting the transport. Can be transported.

The finisher 400 is detachably configured on the copying machine 100, and can be used as an option for the copying machine 100 that can be used alone. In this embodiment, the detachable finisher 400 will be used, but the finisher 400 and the copying machine 100 may be integrated. That is, both the copying machine in which the finisher is an option and the copying machine in which the finisher is integrally incorporated are the image forming apparatus 1000 defined in the present invention.

The copying machine 100 has an operation unit 607. Here, the back side of the copying machine 100 (the back side of the paper surface in FIG. 1) is referred to as the "back side" which is the first side. On the other hand, the side located for the user to perform various inputs / settings to the operation unit 607 is the front side of the copying machine 100 (the front side of the paper in FIG. 1), and this is the second side, "front side". Called "side". Therefore, FIG. 1 shows the copying machine 100 from the front side. The finisher 400 is connected to the left side of the copying machine 100. The names of the front side and the back side are also used in the finisher 400.

FIG. 2 is a cross-sectional view of the finisher 400 as viewed from the front side.

The sheet discharged from the copying machine 100 is carried in from the carry-in port of the finisher 400 and delivered to the shift rollers pairs 105 and 106. The shift operation of the seat S is performed by moving the shift unit 108 toward the front or the back while the delivered seat S is being conveyed to the shift rollers 105 and 106. This shift operation will be described later.

After the shift operation by the shift unit 108, the sheet S conveyed by the transfer roller pair 102, the transfer roller 110, and the separation roller 111 is further conveyed by the buffer roller pair 115. When the sheet S is transported by the buffalo pair 115 and discharged to the loading tray 136, it is guided to the transport path 117 by the upper path switching member 118 and discharged to the loading tray 136 by the discharge roller pair 120. If it is not discharged to the loading tray 136, it is guided to the transport path 121 by the upper path switching member 118, and sequentially passes through the transport path by the buffalo pair 122 and the transport roller pair 124.

When the seat S is saddle-stitched, the saddle path switching member 125 is switched by a driving means (not shown) such as a solenoid, so that the seat S conveyed to the transfer roller pair 124 is guided to the saddle unit 135. It is saddle-stitched.

On the other hand, when the sheet S is discharged to the loading tray 137, the sheet S conveyed to the transfer roller pair 124 is conveyed to the lower path 126 by the saddle switching member 125. The lower pass 126 is provided with a paper ejection sensor 127. After that, the sheet S is discharged to the processing tray 138 by the lower discharge roller pair 128 composed of the discharge rollers 128a and 128b, and a plurality of sheets are stacked in the processing tray 138 to form a sheet bundle, which is subjected to processing such as binding processing by the stapler 134. Will be done. Then, the sheet bundle is discharged to the loading tray 137 by the discharge roller pair 130 including the lower discharge roller 130a and the upper discharge roller 130b.

Next, the configuration and operation of the shift unit 108 will be described with reference to FIGS. 11 and 12.

FIG. 11 is a plan view of the shift unit 108 as viewed from the direction perpendicular to the transport direction and the width direction of the sheet S. FIG. 12 is a perspective view of the shift unit 108.

The shift unit 108 includes shift rollers pairs 105 and 106 as shown in FIGS. 11 and 12. When the seat S is conveyed, the shift transfer motor 308 is driven, and the drive of the shift transfer motor 308 is transmitted to the shift roller pair 106 via the drive belt 309 to drive the shift roller pair 106. Further, the drive of the shift roller pair 106 is transmitted to the shift roller pair 105 via the drive belt 313 to drive the shift roller pair 105. As a result, the sheet S is conveyed in the direction of arrow C.

The shift operation is performed by driving the shift unit 108 in the front / back direction (arrow D direction) by the shift unit moving motor 310 while the seat S is sandwiched between the shift rollers 105 and 106. .. As a result, the sheet S is shifted while being transported in the transport direction C. The direction of arrow E is the same as the direction of arrow D.

Next, the configuration of the processing tray 138 will be described with reference to FIGS. 13 and 14.

FIG. 13 is a vertical cross-sectional view of the processing tray 138. As shown in FIG. 13, the processing tray 138 is tilted so that the downstream side (left side in FIG. 13) is upward and the upstream side (right side in FIG. 13) is downward with respect to the discharge direction of the sheet bundle. It is arranged. A rear end stopper 150 is arranged at a lower end portion on the upstream side of the processing tray 138.

A lower discharge roller 130a of a discharge roller pair 130 is arranged at an upper end portion on the downstream side of the processing tray 138. An upper discharge roller 130b of a discharge roller pair 130 is arranged at the front end of the lower surface of the swing guide 149. A guide guide 151 is arranged in the swing guide 149 in the axial direction. The swing guide 149 is rotatably supported by the support shaft 154 so that it can swing in the vertical direction. The guide guide 151 is provided on the upstream side of the upper discharge roller 130b, and guides the sheet S to the nip portion of the discharge roller pair 130.

The upper discharge roller 130b comes into contact with the lower discharge roller 130a as the swing guide 149 swings to open and close. The discharge roller pair 130 is subjected to rotational drive from a drive motor (not shown) to the upper and lower discharge roller shafts, and rotates in the forward and reverse directions. As a result, the discharge roller pair 130 can convey the sheet S in the external discharge direction for discharging onto the loading tray 137 and the introduction direction for transporting (introducing) the sheet S onto the processing tray 138.

Normally, when the sheet S from the lower pass 126 is introduced into the processing tray 138, the swing guide 149 swings upward, and the upper discharge roller 130b is opened away from the lower discharge roller 130a accordingly. Become. Further, when the processing of the sheet S on the processing tray 138 is completed, the swing guide 149 moves downward, and the sheet bundle is sandwiched between the upper discharge roller 130b and the lower discharge roller 130a. After that, the discharge roller pair 130 rotates with the sheet bundle sandwiched between the upper discharge roller 130b and the lower discharge roller 130a, so that the sheet bundle is discharged to the loading tray 137. In the processing tray 138, for example, the stapler 134 performs a binding process on the rear end portion of the sheet bundle.

FIG. 14 is a view of the processing tray 138 as viewed from diagonally above right of FIG.

The processing tray 138 includes a first matching portion 341 on the back side and a second matching portion 340 on the front side as matching portions for aligning the sheets S in the width direction.

The first and second matching members 341a and 340a, which are matching members, are erected from the first and second matching portions 341 and 340, respectively. These matching members 341a and 340a are wall portions perpendicular to the width direction (depth direction) of the sheet S. The surfaces of the first and second matching members 341a and 340a facing each other are the first and second matching surfaces 341a1 and 340a1.

The driving force of the first and second matching drive motors M341 and M340 is transmitted from the respective tip pulleys to the first and second matching portions 341 and 340 via the timing belts B341 and B340. As a result, the first and second matching portions 341 and 340 can move independently with respect to the processing tray 138 along the width direction of the sheet S. When the first and second matching drive motors M341 and M340 drive the first and second matching portions 341 and 340, respectively, the first and second matching members 341a and 340a are displaced, and the first and second matching members 341a and 340a are displaced. The positions and spacings of the second matching surfaces 341a1 and 340a1 are defined.

Sensors S341 and S340 for detecting the home positions are arranged for the first and second matching portions 341 and 340, respectively. When not operating, the first and second matching portions 341 and 340 are waiting at each home position position (both ends), respectively.

Next, the introduction of the sheet S into the processing tray 138 will be described.

Regarding the sheet S introduced into the processing tray 138, the upstream end on the lower right side of FIG. 13 is referred to as the rear end portion, and the downstream end portion on the upper left side of FIG. 13 is referred to as the front end portion.

It matches the part.

When the sheet S is introduced into the processing tray 138, the front end portion of the sheet S becomes the end portion on the side that first enters between the first matching member 341a and the second matching member 340a. The sheet S starts to be discharged to the processing tray 138 by the lower discharge roller pair 128, and then switches back once, so that the rear end portion of the sheet S faces the rear end stopper 150. Then, the rear end portion of the sheet S comes into contact with the rear end stopper 150, and the first matching member 341a and the second matching member 340a move in a direction approaching each other, thereby aligning the lateral ends of the sheet S. The edge matching operation is performed. The horizontal edge alignment operation is performed before the sheet bundle binding process in the processing tray 138.

As shown in FIG. 13, a belt roller 158 for transporting the sheet S (see also FIG. 2) and a rear end lever 159 for pressing the sheet S are arranged on the upstream side of the processing tray 138.

The seat S introduced into the processing tray 138 is guided upstream by the counterclockwise rotation of the belt roller 158 in FIG. 13 while being guided by the rear end lever 159, and abuts on the rear end stopper 150. As a result, the rear ends of the sheet S are aligned in the transport direction.

The belt roller 158 is hung on the outer circumference of the lower discharge roller 128a constituting the lower discharge roller pair 128 as a conveying means, and rotates counterclockwise in accordance with the rotation of the discharge roller 128a. Further, the belt roller 158 is provided above the processing tray 138 so that its lower portion is in contact with the uppermost sheet loaded on the processing tray 138.

Next, the control unit of the copying machine 100 and the finisher 400 (image forming apparatus 1000) will be described. As shown in FIG. 15, the copying machine 100 according to the present embodiment has a computer 620 connected to the CPU circuit unit 630 via an external interface 637. The CPU circuit unit 630 has a CPU 629, a ROM 631, and a RAM 650, and communicates with a document feeding device control unit 632, an image reader control unit 633, an image signal control unit 634, and a printer control unit 635. Further, it communicates with the operation unit 607, the finisher control unit 636, and the sticky note sticking control unit 640. The detailed control of the CPU 629 will be omitted.

As shown in FIG. 16, the finisher control unit 636 includes a CPU (microcomputer) 701, a RAM 702, a ROM 703, an input / output unit (I / O) 705, a communication interface 706, and a network interface 704. Further, the input / output unit (I / O) 705 includes a transport control unit 707, a shift control unit 712, a processing tray control unit 708, a binding control unit 709, a loading tray control unit 710, and a saddle control unit 711.

Further, the motors (actuators) M120, M122, M112, and M114 for the transfer roller pairs 102 and 124, the transfer roller 110, the separation roller 111, the buffer roller pair 115, 122, and the discharge roller pair 120 are output.

From here, in the finisher 400 of the present embodiment, control when the sheet S to which the sticky note F is attached is discharged from the sticky note sticking device 500 will be described with reference to FIGS. 17 to 18.

FIG. 17 is a diagram showing the operation of the finisher 400 (sheet transfer) when the sticky note F attached to the sheet S overlaps with the roller pair on the transfer path. When the sheet S to which the sticky note F is attached is ejected from the sticky note attaching device 500, it is attached to the sheet S by the CPU 701 (FIG. 16) as a duplication recognition means described later as shown in FIG. 17 (a). When it is recognized that the attached sticky note F overlaps with the transport rollers R1 and R2 on the transport path, the shift unit 108 as a moving means so that the sticky note F is removed from the overlapping area as shown in FIG. 17B.

The transport rollers R1 and R2 are sheet transport means for transporting the sheets in a predetermined transport direction, and the above-mentioned transport rollers 102, 124, transport rollers 110, separation rollers 111, buffer rollers 115, 122, and discharge. It corresponds to a roller pair 120 or the like.

FIG. 18 is a flowchart showing each operation when the sticky note F attached to the sheet S overlaps with any of the roller pairs on the transport path and when they do not overlap.

First, when the sticky note sticking sheet transport control is started, the CPU 701 acquires the paper information and the sticky note F information (S101). Specifically, the CPU 701 as the sticky note position recognizing means recognizes the position of the sticky note F set on the sticky note information setting screen 2000 as described above. When the sheet S to which the sticky note F is attached is delivered from the sticky note pasting device 500 to the finisher 400, the CPU 701 as the duplication recognition means uses the roller pair on the transport path and the sticky note attached to the sheet S. It is determined whether or not F overlaps (S102). For example, the CPU 701 is attached to a roller such as a transfer roller pair 102, 124, a transfer roller 110, a separation roller 111, a buffer roller pair 115, 122, and a discharge roller pair 120 as a sheet transfer means, and a sheet S to be transferred. It is determined whether or not at least a part of the attached sticky note F overlaps in the width direction. The sheet transporting means for avoiding overlap with the sticky note F may include a discharge roller pair 130, a belt roller 158, and the like. The sheet transporting means for avoiding overlap with the sticky note F preferably includes at least a roller or the like on the transport path on which the sheet is transported. When it is determined that the roller pair on the transport path and the sticky note F do not overlap (S102: N), the sheet S is directly transported to the post-processing unit and discharged to the loading tray 136 or 137.

When it is determined in S102 that the roller pair on the transport path and the sticky note F overlap (S102: Y), the CPU 701 stops the sheet S at the shift position in the finisher (S103). For example, the seat S is stopped while being sandwiched between the shift rollers 105 and 106 of the shift unit 108. After that, the CPU 701 as a moving distance recognizing means for recognizing the moving distance when shifting the sheet S to a position where the sticky note F and the roller pair on the transport path do not overlap recognizes the moving distance to the non-overlapping position. (S104). This moving distance recognition means will be described later.

The CPU 701 as the control means shifts the sheet S according to the recognized moving distance so that the sticky note F and the roller pair on the transport path do not overlap each other (S105). For example, the shift unit 108 shifts the seat S. When the shift operation is completed in S105, the sheet S is re-transported in order to transfer the sheet S to the post-processing unit in S106. Then, it is discharged to the loading tray 136 or 137, and the process is completed.

In this embodiment, the sheet S is shifted to avoid contact between the sticky note F and the roller pairs (conveyor roller pairs R1, R2) on the transport path. For example, the rollers on the transport path instead of the sheet S are avoided. There are also a method of shifting the pair and a method of shifting both the sheet S and the roller pair on the transport path to avoid contact, and the present invention is not limited to this embodiment. That is, so that the sticky note F and the transfer rollers R1 and R2 do not overlap, at least one of the sheet conveyed by the transfer rollers R1 and R2 and the transfer rollers R1 and R2 is in the transfer direction with respect to the other. Move relatively in the orthogonal width direction. For example, before the sheet S is conveyed to the shift unit 108, the shift rollers 105 and 106 as the sheet conveying means may be moved to a position that does not overlap with the sticky note on the sheet S. In this case, the shift roller pairs 105 and 106 correspond to the transport roller pairs R1 and R2.

Further, both the sheet and the transfer rollers R1 and R2 may be moved so that the sticky note F and the transfer rollers R1 and R2 do not overlap. For example, before the sheet S is conveyed to the shift unit 108, the shift rollers 105 and 106 are moved to positions that do not overlap with the sticky notes on the sheet S, and then the sticky notes F are moved by the shift rollers 105 and 106. With the attached sheet S sandwiched between the rollers such as the transfer rollers 102 and 124, the transfer rollers 110, the separation rollers 111, the buffer rollers 115 and 122, and the discharge rollers 120, the sticky note F does not overlap. In addition, the seat S may be moved by the shift unit 108.

Further, although not particularly shown in this flowchart, if either the sheet S or the roller pair on the transport path is shifted and the roller pair on the transport path and the sticky note F overlap, the sheet is transported. You may control to let the user choose whether or not to do.

Next, the means of recognizing the overlap between the sticky note F attached to the sheet S and the roller pair on the transport path will be described. FIG. 19 is a diagram showing a method of determining whether or not the attached sticky note F overlaps with any of the roller pairs on the transport path.

First, the CPU 701 acquires the sticky note F sticking position m set on the sticky note information setting screen 2000. m represents the position of the sticky note F when the center of the transport width is 0 with respect to the transport direction. (The front side of the device is + (plus) m and the rear side is- (minus) m based on the center).

Next, it is determined whether or not the sticky note F overlaps with the roller pair on the transport path. The position and width of the roller pair on the transport path are recognized in advance by the CPU 701. Here, the position of the transport roller vs. R2 is n, the position of the transport roller vs. R1 is p, and the roller width is 35 mm. .. These n and p also represent the positions of the transport rollers when the center of the transport width is 0.

When the sticky note F and the transport roller are in the positional relationship shown in FIG. 19, the overlapping range is n or more (p + 35) or less in the width direction. Therefore, the CPU 701 determines whether or not the sticky note F sticking position m is within the above-mentioned range, and recognizes that the sticky note F overlaps with at least one of the transport roller pairs R1 and R2. .. On the other hand, if it is out of range, it is recognized that it does not overlap. In this way, it is recognized whether or not there is overlap from the position of the pair of rollers on the transport path and the sticky position of the sticky note F.

In the present embodiment, it is recognized whether or not the sticky note F attached to the sheet S overlaps with any of the roller pairs on the transport path by the method described above, but as a means for recognizing the overlap, a sensor is used. It may be recognized whether or not there is duplication by a method such as information or image recognition, and the method is not limited to this method.

Next, with reference to FIG. 19, a moving distance recognizing means for recognizing the moving distance when shifting the sheet S to a position where the sticky note F attached to the sheet S and the roller pair on the transport path do not overlap. explain.

When it is recognized by the duplication recognition means described above that they overlap, it is necessary to shift the sticky note F to a position where it does not overlap with the transfer roller pair in order to avoid contact. At that time, in FIG. 19, the sheet S is shifted in any of the directions A and B in the direction orthogonal to the transport direction. The moving distance in the direction of A at this time is recognized by (mn) + 10 (width of sticky note F). On the other hand, the moving distance in the direction of B is recognized by (p + 35) -m.

The CPU 701 recognizes the shorter moving distance in the recognized directions A and B as the shift direction. That is, in the present embodiment, A is recognized as the shift direction and the moving distance. If the recognized movement distance exceeds the shiftable range, the maximum shift operation is performed within the shiftable range. The shiftable range is, for example, a range in which the shift unit 108 can move the seat in the width direction based on the seat size. It should be noted that this moving distance recognition means is also an example in the present embodiment, and the moving distance may be recognized by another method, and it goes without saying that the moving distance recognition means is not limited to this method.

Finally, in the present embodiment, when it is recognized by the overlap recognition means that the sticky note F attached to the sheet S and the transfer means such as the transfer roller overlap, the sheet S is attached by shifting the sheet S. Although the contact between the sticky note F and the transport means such as the transport roller was avoided, the sheet is not disturbed by the shift operation so that the alignment with the sheet already loaded on the loading tray 137 (already loaded sheet) is not disturbed. It is desirable to discharge the paper to the loading tray 137 as the loading means.

Therefore, as a method of maintaining the alignment at the time of discharging, there is a method of shifting the shifted seat S again before discharging and controlling the seat S to move to the same position as the already loaded seat. In the present embodiment, as an example, the shift unit 108 described above is used as the first moving means, and the first and second matching portions 341 and 340 for aligning the sheets S in the width direction provided in the processing tray 138. Is used as a second means of transportation to show a method for maintaining alignment at the time of discharge.

FIG. 20 shows the sheet S shifted by the shift unit 108 as the first moving means at the same position as the already loaded sheet on the first and second matching portions 341 and 340 as the second moving means of the processing tray 138. It is a figure which showed the operation of shifting to and discharging to a loading tray 137.

First, as shown in FIG. 20A, the sheet S in a state where contact between the attached sticky note F and the sheet conveying means such as the conveying roller is avoided is conveyed to the processing tray 138. Next, in FIG. 20B, the sheet S loaded on the processing tray 138 is shifted by the matching portions 341 and 340 so as to move to the same position as the already loaded sheet. That is, the CPU 701 as the loading position recognizing means recognizes the loading position of the sheets loaded by the loading tray 137. Then, the CPU 701 moves the matching units 341 and 340 to the same position as the loading position recognized by the loading position recognizing means so that the sheet moved by the shift unit 108 to a position where the sticky note F and the sheet conveying means do not overlap. Control. In the present embodiment, the moving distance of the seat S by the matching portions 341 and 340 at this time is the moving distance shifted by the shift unit 108, and the seat S is returned by the moving distance (the direction moved by the shift unit 108). (Move in the opposite direction to). After that, in FIGS. 20 (c) and 20 (d), the bundle of sheets S whose alignment has been adjusted is discharged to the loading tray 137 by the discharge roller pair 130. In this way, by shifting again by the matching portions 341 and 340, it is possible to maintain the alignment at the time of paper ejection.

As described above, according to the present embodiment, when it is recognized by the overlap recognition means that the sticky note F attached to the sheet S and the transfer means such as the transfer roller overlap, in order to avoid contact. By shifting the sheet S to a position where the sticky note F attached to the sheet S and the roller pair on the transport path do not overlap, or by shifting the roller pair on the transport path, the sticky note F and the roller The sheet S can be conveyed while avoiding contact, and the sheet S can be conveyed without stopping or interrupting the transfer.
