<Example of operation and effect of the stapler of the first embodiment for detecting full load of cut needles>
In the conventional stapler mounted on the post-processing device, the cut needle storage portion is provided on the post-processing device side, and the cut needle is temporarily stored in the discharge path of the cut needle provided in the stapler, and the stapler is stored at a predetermined timing. Was moved to the position of the cut needle storage part, and the cut needle was discharged from the stapler to the cut needle storage part.

As described above, conventionally, in order to collect the cut needles, it is necessary to move the stapler to the position of the cut needle storage portion provided on the post-processing device side, which reduces the productivity of the booklet for binding the paper with the needles. .. Further, if the number of cut needles temporarily stored in the discharge path provided in the stapler is large, the cut needle is moved from the discharge path into the post-processing device without the stapler being moved to the position of the cut needle storage portion. There was a possibility of leaking to.

On the other hand, in the stapler 1Ra, since the stapler 1Ra is provided with the stapler 1Ra, the stapler 13A can be stored in the stapler storage portion 6R regardless of the position of the stapler 1Ra in the post-processing device 502A. Can be done. As a result, it is not necessary to move the stapler 1Ra to a specific position in order to collect the cut needles, and the productivity of the booklet for binding the paper with the needles is improved.

Further, the cut needle storage unit 6R has a size sufficient to store all the cut needles 13A even when the needle foot 12A of the number of needles 10A that can be stored in the needle cartridge 100R is cut to the maximum length. Since it has a large capacity, it is not necessary to collect the cut needle 13A until the timing of replenishing the needle 10A. As a result, the number of times the cut needle 13A is collected from the stapler 1Ra can be reduced, and the number of times the operation of the image forming system 500A is stopped due to the collection of the cut needle 13A can be reduced. Productivity is improved.

In the stapler 1Ra, when the cam 51R in stitching work sheet with needles rotates, the link portion 53R _L contacts the movable portion 95Ra _L in operation is lifting, the link portion 53R contact the moving part 95Ra _R in operation _R is lifting.

If the amount of cutting needles 13A which is accommodated in the cut needle storage portion 6R is small, the contact movable portion 95Ra _L is moved to a non-full detecting position is pressed downward by the spring 97Ra _L, sensor 96R _L Is detected by. Further, the contact movable portion 95Ra _R is pressed downward by the spring 97Ra _R and moved to the non-full load detection position, and is detected by the _{sensor 96R R.} Therefore, it can be detected that the amount of the cut needle 13A is not full.

If the amount of cutting needles 13A which is accommodated in the cut needle storage portion 6R becomes full, the contact movable portion 95Ra _L stops in raised position unable lowered to a non-full detecting position, the non-detection by the sensor 96R _L .. The contact movable portion 95Ra _R stops at elevated positions unable lowered to a non-full detecting position, the non-detection by the sensor 96R _R. Therefore, it can be detected that the amount of the cut needle 13A is full.

In the post-processing device 502A described with reference to FIG. 2 and the like, the stapler 1Ra is tilted depending on the position of the stapler 1Ra, as shown in FIG. In this case, in the present example, in one recovery path 60R _L side cut needle storage portion 6R, stacking height of the cut needle 13A is lowered. Therefore, the contact movable portion 95Ra _L is lowered to a non-full detecting position is detected by the sensor 96R _L. Meanwhile, on the other hand the recovery path 60R _R side cut needle storage portion 6R, the higher the stacking height of the cut needle 13A. Therefore, the contact movable portion 95Ra _R stops at elevated positions unable lowered to a non-full detecting position, the non-detection by the sensor 96R _R. Therefore, even when the stapler 1Ra is tilted, it is possible to accurately detect whether or not the amount of the cut needle 13A is full.

Further, by providing the sensor _96R L, the 96R _R the post-processing apparatus 502A, the cutting needle storage portion 6R is not attached to the stapler 1Ra, contact the movable portion 95Ra _L, 95Ra _R is non-detection. As a result, the same detection unit can be used for both full load detection for detecting that the amount of cut needles is full and detection for the presence or absence of the cut needle storage unit 6R.

As shown in FIG. 5, the cut needle storage portion 6R has a structure that can be attached to and detached from the stapler 1Ra, so that the cut needle 13A can be collected by removing the cut needle storage portion 6R from the stapler 1Ra. When the cut needle 13A is collected, it is possible to suppress the occurrence of problems such as the cut needle 13A spilling into the post-processing device 502A.

In this example, the cut needle accommodating portion 6R is attached / detached by moving the stapler 1Ra to the first position Pp1 shown in FIG. 2 and opening the door 505A. The recovery of the cut needle 13A, the recovery port _61R L of the cut needle storage portion 6R, from 61R _R, or is performed openable discharge opening (not shown). Further, the cut needle storage portion 6R itself may be replaced.

In the stapler 1Ra, the needle cartridge 100R can be attached and detached with the cut needle accommodating portion 6R attached. As a result, by moving the stapler 1Ra to the first position Pp1 shown in FIG. 2 and opening the door 505A, the needle cartridge 100R can be attached and detached without removing the cut needle storage portion 6R, and the needle 10A can be replenished. It can be carried out.

Further, since the cut needle storage portion 6R is attached to the back side of the stapler 1Ra, even if the capacity of the cut needle storage portion 6R is increased, it is suppressed that the size of the needle cartridge 100R is restricted, and the cut needle storage portion is suppressed. The number of needles 10A that can be stored can be maintained or increased as compared with the configuration that does not have 6R.

As shown in FIG. 2, in the operation of moving the stapler 1Ra to a predetermined binding position, the stapler 1Ra reciprocates, so that the cut needle 13A stored in the cut needle storage portion 6R is subjected to a force in the left-right direction. Is hung. As a result, the cut needle 13A can be stored evenly at a substantially uniform height by suppressing the deviation of the cut needle 13A in the cut needle storage portion 6R.

When the stored cut needle 13A becomes bulky due to deviation, the processing is stopped by detecting the full load of the cut needle 13A, and the cut needle 13A is stored even if the cut needle storage portion 6R still has a remaining capacity. The cut needle storage unit 6R cannot be used effectively. On the other hand, by suppressing the offset of the cut needle 13A and storing the cut needle 13A evenly at a substantially uniform height, false detection due to the offset of the stored cut needle 13A is suppressed. The cut needle storage unit 6R can be effectively used.

As shown in FIG. 1, the stapler 1Ra mounted on the post-processing device 502A is tilted so that the paper holding portion 4R side faces upward, and moves according to the binding position as shown in FIG. Therefore, the position of the stapler 1Ra, discharge passage 33R _L and the discharge passage 33R _R tilt of the discharge passage 33R _L and the discharge passage 33R height between the _R, the inclination of the cutting needle storage portion 6R, and a recovery passage 60R _L height between the collection path 60R _R is changed.

Therefore, the stapler 1Ra the first position Pp1 shown in FIG. 2, be moved to any of the second position Pp2 or third position Pp3, at least one of the discharge passage 33R _L and the discharge passage 33R _R is cut parts 30R from the discharge port _34R L, configured 34R _R is low. Further, the cut needle storage portion 6R does not depend on the position of the stapler 1Ra in the post-processing apparatus 502A, the body portion of the cutting needle storage portion 6R is below the one or both of the recovery path 60R _L or collection route 60R _R It is configured to be located.

As a result, regardless of whether the stapler 1Ra moves to the first position Pp1, the second position Pp2, or the third position Pp3 in the binding operation, the cut needle 13A cut by the cut portion 30R becomes the cut portion 30R. , it can be suppressed staying in the discharge passage 33R _L and the discharge passage 33R _R. Further, it is possible to prevent the discharge passage 33R _L and cutting needles 13A which are discharged from the discharge passage 33R _R is staying in the recovery passage 60R _L and recovery passage 60R _R. Therefore, the cut needle 13A cut by the cut portion 30R can be stored in the cut needle storage portion 6R.

The stapling operation of the sheet P in the stapler 1Ra, by binding unit 3R at a rotational operation with the fulcrum shaft 32R is moved, the discharge passage 33R _L and the discharge passage 33R _R is moved. When the amount of movement of the discharge port of the discharge port becomes large, the collection port of the cut needle accommodating portion to which the discharge port is connected needs to be sized according to the movement range of the discharge port, so that the stapler becomes large.

In contrast, the outlet 34R _R outlet 34R _L and the other discharge path 33R _R of one discharge channel 33R _L, by arranging in the vicinity of the shaft 32R, the movement of the outlet 34R _L and the discharge port 34R _R The amount can be kept small, and the stapler 1Ra can be miniaturized.

Also, one of the recovery port 61R _L of the cut needle storage portion 6R, as one of the discharge passage 33R _L outlet 34R _L enters embodiment, and the discharge port 34R _L within the opening of the recovery port 61R _L moves The configuration is such that it can be done. Similarly, the other recovery port 61R _R cut needle storage portion 6R, as the other exhaust passage 33R _R of the outlet 34A _R enters embodiment, and the discharge port 34R _R within the opening of the recovery port 61R _R It is configured to be movable. As a result, it is possible to suppress leakage of the cut needle 13A to the outside at the connecting portion between the cut needle accommodating portion 6R and the discharge path 33R.

Further, as shown in FIG. 32, the contact movable portion 95Re _R cannot move to the non-full load detection position and stops at the position moved forward. Therefore, it can be detected that the amount of the cut needle 13A is full.

In the post-processing device 502A described with reference to FIG. 2 and the like, the stapler 1Re is in an inclined state as shown in FIG. 33 depending on the position of the stapler 1Re. In this case, in the present embodiment, the recovery path 60R _R side cut needle storage portion 6R, the higher the stacking height of the cut needle 13A. Therefore, the contact movable portion 95Re _R cannot move to the non-full load detection position and stops at the position moved forward.

In contrast, in the recovery path 60R _L side cut needle storage portion 6R, stacking height of the cut needle 13A is lowered. However, since the link 98Re _L and the link 98Re _R are connected by the shaft 98R ₁ and interlocked with each other, the contact movable portion 95Re _L cannot move to the non-full load detection position and moves forward regardless of the loading height of the cut needle 13A. It stopped at a position, the non-detection by the sensor 96R _L. As a result, it is possible to accurately detect whether or not the amount of the cut needle 13A is full with one sensor regardless of the direction of inclination of the stapler 1Re.

In the present embodiment, the display unit 603, the indicator light 604, and the buzzer 605 show an example of the notification means for notifying the user of information, and the present invention is not limited thereto. For example, the operation unit 602 and the display unit 603 may be an operation panel integrally formed.

The post-processing device 502A includes a sub-control unit 601 as a control means for controlling the post-processing device 502A, a moving unit 606 for moving the stapler 1R, and a safety detecting unit 607 for detecting the opening and closing of the door 505A. Further, the post-processing device 502A includes a stapler 1R, and the stapler 1R has a drive unit 5A, a cut needle amount detection unit 94R, and a needle detection unit that detects the presence / absence and the remaining amount of the needle 10A housed in the needle cartridge 100R. 608 is provided.

<Operation example of the image forming system of the present embodiment>
In this example, the image forming apparatus 501A forms an image on the paper by forming a latent image by scanning exposure, developing the latent image by toner, transferring and fixing the toner on the paper.

The post-processing device 502A performs an operation of binding the paper by punching out the needle 10A, cutting the needle foot 12A based on the number of sheets of paper, and bending the needle foot 12A.

In the post-processing device 502A, the main control unit 600 and the sub-control unit 601 perform predetermined control by full load detection that detects that the remaining amount of the needle 10A and the amount of the cut needle 13A are full. In addition, control is performed to accurately perform full load detection that detects that the amount of the cut needle 13A is full.

In the post-processing device 502A, when the operation of binding the paper is executed a predetermined number of times, the stapler 1R is moved. For example, when the binding operation is performed at the first position Pp1 shown in FIG. 2, the stapler 1R is inclined in the left-right direction. Therefore, since the cut needle storage portion 6R is inclined, the cut needle 13A stored in the cut needle storage portion 6R is offset, and the bulk is different on the left and right.

Therefore, when the paper binding operation is executed a predetermined number of times, the moving unit 606 is driven to reciprocate the stapler 1R at the second position Pp2 in this example, whereby the cutting needle stored in the cutting needle storage unit 6R is reciprocated. The operation of leveling 13A is performed. The number of reciprocating movements may be one or more.

Further, the stapler 1R may be reciprocated at an arbitrary timing while the operation of binding the paper with the stapler 1R is stopped or the post-processing device 502A is on standby. In this case, the stapler 1R may be reciprocated regardless of the number of times the paper binding operation is executed.

When the stapler 1R is reciprocated, a force is applied to the cut needle 13A stored in the cut needle storage portion 6R in the left-right direction. As a result, the cut needle 13A can be stored evenly at a substantially uniform height by suppressing the deviation of the cut needle 13A in the cut needle storage portion 6R. Therefore, the capacity of the cut needle storage unit 6R can be effectively utilized.

In the above-described stapler 1Ra etc., in one recovery path 60R _L side and the other of the collection passage 60R _R side, the contact movable portion 95Ra _L contact the movable portion 95Ra _R can operate independently, sensor 96R _L, sensor It can determine the presence or absence of Katayose cut needle 13A from the output of the 96R _R. As a result, if it is determined that the cut needle 13A is offset, the stapler 1R may perform the operation of leveling the offset due to the reciprocating movement of the stapler 1R.

Further, in the post-processing device 502A, the stapler 1R is not tilted in the left-right direction, and the full load detection position, which is a suitable position for detecting whether or not the amount of the cut needle 13A is full, is used in this example. The stapler 1R is moved to the second position Pp2, and the cut needle amount detection unit 94R detects whether or not the amount of the cut needle 13A is full, and detects the fullness of the cut needle 13A.

First, in order to eliminate the deviation of the cut needle 13A in the cut needle storage portion 6R, as described above, when the paper binding operation is executed a predetermined number of times, the stapler 1R is reciprocated at the second position Pp2. conduct.

Next, the position where the stapler 1R is stopped is determined, and in this example, the stapler 1R is stopped at the second position Pp2, and the cut needle amount detecting unit 94R detects the full load. As a result, it is possible to detect the full load of the cut needle 13A in a state where the offset of the cut needle 13A in the cut needle storage portion 6R is eliminated, so that it is possible to detect whether or not the amount of the cut needle 13A is full. Full load detection can be performed accurately.

At the second position Pp2 where the full load detection of the cut needle 13A is performed, the cut needle accommodating portion 6R cannot be attached to or detached from the stapler 1R. Therefore, in the post-processing device 502A, the standby position of the stapler 1R is set to the removable position of the cut needle accommodating portion 6R. For example, if the home position of the stapler 1R is the removable position of the cut needle storage portion 6R, the stapler 1R is moved to the detachable position of the cut needle storage portion 6R such as the home position and stands by. As a result, the cut needle accommodating portion 6R can be attached and detached to collect the cut needle not only at a predetermined timing such as after the full load detection of the cut needle 13A but also at an arbitrary timing before the full load detection.

Further, by performing the binding operation with the stapler 1R tilted to the left and right, after it is detected that the amount of the cut needle 13A is full, the cut needle 13A is offset in the cut needle storage portion 6R described above. It may not be detected that the amount of the cut needle 13A is full due to the operation of eliminating the above.

Therefore, after the binding operation a plurality of times, the stapler 1R is reciprocated as described above to detect whether or not the amount of the cut needle 13A is full, and the amount of the cut needle 13A is full. The number of times that this is detected is counted, and when the number of times that the amount of the cut needle 13A is detected to be full is equal to or greater than the predetermined number of times, it is determined that the amount of the cut needle 13A is full. .. As a result, when the capacity of the cut needle 13A is increased, it is possible to more accurately detect whether or not the amount of the cut needle 13A is full.

The full load detection of the cut needle 13A may be performed not only by moving the stapler 1R to a predetermined position such as the second position Pp2, but also at all times. The term “always” here includes the case where the stapler is performed at predetermined time intervals regardless of the position of the stapler 1R.

When the post-processing device 502A determines that the remaining amount of the needle 10A stored in the needle cartridge 100R has reached a predetermined number by the needle detection unit 608, the remaining number of needles such as stopping the operation or performing a predetermined number of binding operations. Control is performed according to. It is considered that when the number of needles 10A stored in the needle cartridge 100R decreases, the capacity of the cutting needle 13A in the cutting needle storage portion 6R increases. Therefore, when the needle detection unit 608 performs near-end detection for detecting that the remaining amount of the needle 10A stored in the needle cartridge 100R has decreased and end detection for detecting that the remaining amount of the needle 10A has been exhausted, The display unit 603, the indicator light 604, the buzzer 605, or a combination thereof gives a notification prompting the collection of the cut needle.

When the end and near end detection of the needle 10A is performed, the operation of replenishing the needle 10A is performed, so that the operation of stopping the device once and opening the door 505A is performed. The number of times the device is stopped can be reduced by prompting the collection of the cut needle 13A at the timing of replenishing the needle 10A regardless of the presence or absence of full load detection by the cut needle amount detecting unit 94R.

In the operation of collecting the cut needle 13A, the operation of attaching / detaching the cut needle accommodating portion 6R to / from the stapler 1R is performed. Therefore, the remaining amount of the cut needle can be predicted based on the number of actual hits, the number of binding processes, the number of sheets, etc. between the interval between the attachment / detachment of the cut needle storage portion 6R and the interval between the attachment / detachment of the cut needle storage portion 6R. As a result, a notification prompting the collection of the cut needle can be made at a predetermined timing before the full load detection by the cut needle amount detection unit 94R, and the cut needle can be collected by using the timing when the device is not operating. can. Further, the amount of the cut needle may be predicted based on the length of the cut needle foot.

Further, when setting the job, the amount of the cut needle 13A that can be generated from the number of sheets to be bound, the number of bound copies, etc. is predicted, and the remaining amount of the cut needle 13A that can be stored in the cut needle storage section 6R is predicted. If it is determined that the cut needle 13A is full during the execution of the job, a notification prompting the collection of the cut needle may be given at a predetermined timing before the full load detection of the cut needle 13A is performed.

In the aftertreatment device 502A, when the safety detection unit 607 detects that the door 505A has opened, the power supply is stopped. However, if the cut needle storage unit 6R cannot detect, the presence or absence of full load detection cannot be output. Therefore, when the safety detection unit 607 detects that the door 505A has opened, the sub-control unit 601 and the cut needle amount detection unit 94R Continue to supply power to. As a result, full load detection can be notified even when the door 505A is open.

Further, when the safety detection unit 607 detects that the door 505A has been opened, a notification prompting the collection of the cut needle may be given, based on the number of times the door 505A is opened and closed, the number of times the cut needle storage unit 6R is attached / detached, and the interval. , The remaining amount of the cut needle may be predicted. Further, the amount of the cut needle 13A that detects that the cut needle 13A is fully loaded may be set by the user on the operation unit 602.

As described above, the cut needle amount detection unit that detects the amount of the cut needle stored in the cut needle storage unit 6R is not limited to the sensor, and the main control unit 600 is based on counting, detecting, and the like that a predetermined operation has been performed. , The sub-control unit 601 can make a judgment.

Further, the weight of the cut needle accommodating portion 6R and the weight of the stapler 1R may be detected to predict the amount of the cut needle.

Further, in the configuration in which the cut needle amount detection unit 94R detects the full load of the cut needle and the attachment / detachment detection of the cut needle storage unit 6R, the notification that the cut needle is full and the attachment of the cut needle storage unit 6R are insufficient. Notification that there is, and notification that the cut needle storage unit 6R is not attached are also performed.

It should be noted that, based on the detection of a predetermined state by the cut needle amount detection unit 94R and the operation before and after the execution job or the state detection, the cut needle full load detection or the cut needle storage unit 6R attachment / detachment state is detected. It may be determined whether the notification content is changed and the notification content may be changed.

That is, if the cut needle amount detection unit 94R detects during the execution of the paper binding job, it is determined that the cut needles are full, and the cut needles are notified that the cut needles are full. On the other hand, if the cut needle amount detection unit 94R detects immediately after detecting that the door 505A of the aftertreatment device 502A is closed, the cut needle storage unit 6R is not sufficiently attached and the cut is performed. It is also assumed that the needle storage unit 6R is not attached. Therefore, the notification that the cut needle is full, the notification that the cut needle storage portion 6R is insufficiently attached, and the notification that the cut needle storage portion 6R is not attached are combined.

When the full load of the cut needles is detected, the image forming system 500A determines whether to execute the remaining paper processing jobs for the paper processing job being executed, and controls the execution and stop of the paper processing jobs. It may be controlled that the next job is not executed until the executing job is completed and the collection of the cut needle is determined. When the running job is completed, a notification prompting the collection of the cut needle is given. Further, it may be determined whether or not the job can be executed from the number of remaining bindings of the job being executed. Further, if the job does not cut the needle foot, the job may be continued even after the full load of the cut needle is detected. Further, if it is determined that the job is interrupted for some reason after the full load of the cut needles is detected, a notification prompting the collection of the cut needles may be given.

Further, when the full load of the cut needles is detected, as described above, the stapler 1R is reciprocated at a predetermined position to level the cut needles 13A stored in the cut needle storage unit 6R. For the paper processing job being executed, the remaining paper processing jobs may be continued.

On the other hand, after the full load of the cut needle is detected, the full load of the cut needle 13A is not detected by the operation of eliminating the deviation of the cut needle 13A in the cut needle storage portion 6R described above. Even in such a case, the job may not be executed until it is determined that the cut needle is to be collected.

When the full load of the cut needle is detected, after the job is stopped, the stapler 1R is moved to the detachable position of the cut needle storage portion 6R such as the home position and stands by.

As described above, the post-processing device 502A performs full load detection after eliminating the deviation of the cut needle 13A stored in the cut needle storage unit 6R, and also detects full load at a position where the stapler 1R does not tilt to the left or right. Conditions suitable for full load detection are set.

In the post-processing device 502A, when the stapler 1R is used to bind the paper, the stapler 1R vibrates. Further, even after the binding operation is completed, the vibration of the stapler 1R continues for a predetermined time. When the stapler 1R is vibrating, the upper surface of the cut needle 13A stored in the cut needle storage portion 6R vibrates, so that the upper surface of the cut needle 13A temporarily reaches the full load position and is mistakenly full. May be detected.

Therefore, as a full load detection condition, it is determined whether the stapler 1R is in a state where vibration that causes false detection of full load detection can occur, and during the operation of binding the paper with the stapler 1R, while the stapler 1R is being moved to the binding position or the like. , Full load detection is not performed because the full load detection conditions are not met. In addition, the vibration convergence time, which is the time for reducing the vibration that causes false detection of full load detection to the extent that it does not cause false detection, is set, and the vibration convergence time starts from a predetermined timing after the start of operation of the stapler 1R. Full load detection is not performed until.

For example, after the stapler 1R finishes binding the paper, the stapler 1R is moved to the home position, and the vibration convergence time elapses, it is determined that the full load detection condition is satisfied, and the cut needle amount detection unit 94R detects the paper. .. Here, if the full load detection position of the cut needle is different from the home position, the cut needle amount detection unit 94R detects when the vibration convergence time elapses after moving the stapler 1R to the full load detection position.

The post-processing device 502A may be provided with a vibration detection sensor that detects vibration, and if vibration that causes false detection of full load detection is detected, full load detection may not be performed.

In addition to the stapler, the post-processing device includes a device for drilling holes in paper, a device for aligning paper, a device for cutting paper, a device for bending paper, and the like. Therefore, while the operation of the post-processing device other than these staplers is not completed, the cut needle amount detecting unit 94R performs detection. Further, the vibration convergence time is also set for the post-processing devices other than the stapler, and when the vibration convergence time elapses after the operation of the post-processing device other than the stapler is completed, the cut needle amount detection unit 94R detects the vibration convergence time. May be good.
