The present invention relates to a sheet processing apparatus for processing sheets such as marketable securities and more particularly to an electromagnetic locking method of a stacking device loaded on the concerned apparatus.
The sheet processing apparatus for processing sheets such as marketable securities is an apparatus for taking out and conveying sheets one by one by a take-out device from sheet bundles inserted in a batch according to the processing unit, checking for the quality (shape, damage, blurred print, stains, etc.) of the concerned sheets by the sheet check device, sorting the sheets into normal bills (hereinafter, referred to as quality bills), abnormal bills (hereinafter, referred to as disqualified bills), and rejected bills such as abnormal conveying bills and double feed bills and temporarily stacking them in a stacking device, and sealing them, when the number of sheets stacked temporarily reaches a predetermined number of sheets, by paper straps. For example, quality bills are sealed by a paper strap as a binding strap for each 100 sheets so as to form a bunch and 10 bunches are stacked up whenever necessary and are sealed additionally by a paper strap so as to form a bundle.
In the sheet processing apparatus, since counted sheets are stacked on the stacking device, from the viewpoint of security, the stacking device is locked (turned on) by an electromagnetic lock. Conventionally, the locking by the electromagnetic lock is performed regardless of the door condition of the sheet processing apparatus (for example, refer to Patent Document 1).

Hereinafter, the embodiments of the present invention will be explained with reference to the accompanying drawings.
The sheet processing apparatus 100 shown in
The first unit 2, which is a preprocessing portion for supplying sheets P to a take-out device 4, includes a keyboard for inputting by an operator, an operation display device 33 having a display device such as input device such as a mouse or a touch panel and a display such as a CRT or a liquid crystal display for notifying to the operator, the take-out device 4, a conveyance detection apparatus 5a, and rejected bill stacking devices 75 and 76 and is equipped with doors 102a and 102b so as to access these devices
The second unit 103 includes a sheet check device 6, stacking devices 73 and 74, and a 100-sheets sealing device 83 and is equipped with doors 103a and 103b so as to access these devices.
The third unit 104 includes the sheet check device for checking for the thickness and breaking of sheets, stacking devices 71 and 72, and 100-sheets sealing devices 81 and 82 and is equipped with doors 104a and 104b so as to access these devices.
The fourth unit 105 includes a bundle moving device 9, a print reading device 10, and a 100-sheets sealing device 11 and is equipped with a door 105a so as to access these devices.
The fifth unit 106 includes a label issuing-attaching device 12 and is equipped with the door 105a so as to access the unit. Further, the fifth unit is an optional unit.
Hereinafter, the constitution and function of the apparatus composing the aforementioned units will be explained roughly. The take-out device 4 includes a supply portion 4a for supplying sheet bundles in a batch and a take-out portion 4b for taking out the sheets P supplied to the supply portion 4a one by one at a fixed interval.
The supply portion 4a includes a backup plate 4a1 as a supply table for loading a sheet bundle and a take-out position detection device (not shown) for detecting the take-out position of the sheet P on the uppermost surface of the sheet bundle loaded on the backup plate 4a1. On the basis of the detection results of the take-out position detection device, so as to move the sheet on the uppermost surface of the sheet bundle to the take-out position, the supply portion 4a is equipped with a drive device (not shown) for driving vertically the backup plate 4a1.
The take-out portion 4b is composed of a take-out roller (not shown) and a drive device therefor (not shown). The take-out roller is structured so as to be internally at a negative pressure and whenever the take-out roller makes one revolution, one sheet P at the uppermost position of stacked sheets is attracted. One sheet is taken out in correspondence with the rotation of the take-out roller, so that the sheets P are sent onto a conveying path 5 continuously at a fixed interval.
The conveying path 5 is composed of a conveying belt, a conveying roller, and a drive motor (not shown). Further, a branching gate for deciding the conveying destination of the sheets P conveyed by the conveying path 5 is controlled by a conveyance controller 20.
The sheets P taken out by the take-out device 4 is detected and discriminated the conveying condition of the sheets by a sensor (the conveying condition detection sensor 5a) arranged on the downstream side of the take-out device 4 in the conveying direction. As a result of the discrimination, the sheets P detected for a displacement of conveyance, a skew, or double feed cannot be checked, so that they are stacked on the rejected bill stacking device 76.
The sheet check device 6 includes a sheet check device 6a for checking the bottom of the sheets P conveyed and a sheet check device 6b for checking the top thereof. The sheet check devices 6a and 6b are structured similarly to each other and are respectively composed of a sensor for detecting the sheets P conveyed, a light source for lighting the sheets P, and a camera for imaging reflected light from the sheets P and read images obtained from the camera.
The sheet check devices 6a and 6b check for the quality (shape, damage, blurred print, stains, etc.) of the conveyed sheets P and discriminate them as quality bills, disqualified bills, and rejected bills such as abnormal conveying bills and double feed bills. On the basis of the discrimination results, the aforementioned branching gate is controlled and the sheets P are sorted and conveyed.
The stacking device 7 includes the stacking devices 71 and 72 for stacking quality bills and the stacking devices 73 and 74 for stacking disqualified bills. The stacking devices 7 have a paddle wheel stacking device, stop the sheets P conveyed at a high speed by absorbing the conveying speed of the sheets P, and stack them on a stacking storage (not shown).
The quality bills, on the basis of the discrimination results by the sheet check device 6, are controlled by a conveying-sorting device and are stacked on the stacking devices 71 and 72. The stacking method of the quality bill stacking device will be separately described in detail. The disqualified bills are controlled by the conveying-sorting device similarly to the quality bills and are stacked on the stacking devices 73 and 74. Further, undiscriminatable bills such as different kind bills detected by the sheet check device 6 are similarly controlled by the conveying-sorting device and are stacked on the rejected bill stacking device 75.
Further, when the sheet stacking device 100 processes new bills as shown in this embodiment, the majority of the sheets P is occupied by quality bills, so that as mentioned above, in the quality bill stacking device, three stacking devices 71 to 73 are arranged and in the disqualified bill stacking device, one stacking device 74 may be arranged.
Hereinafter, the situation that quality bills are stacked on the stacking devices 71 and 72 and are sealed by the 100-sheets sealing devices 81 and 82 will be explained. Further, when disqualified bills are stacked on the stacking devices 73 and 74, the same man be said, so that the explanation thereof will be omitted. A conveying-sorting device 13, when the sheets P stacked on the stacking device 71 reach 100 sheets, switches a distribution gate (not shown), prevents the sheets P from being conveyed continuously to the stacking device 71, and stacks the sheets P conveyed continuously on the quality bill stacking device 72. The sheets stacked on the stacking device 71 are transferred to the 100-sheets sealing device 81 arranged on the lower part, and 100 sheets are sealed by a paper strap, thus a bunch H is formed.
When the sheets P stacked on the quality bill stacking device 72 reach 100 sheets, the conveying-sorting device 13 switches the distribution gate (not shown), prevents the sheets P from being conveyed continuously to the quality bill stacking device 72, and stacks the sheets P conveyed continuously on the stacking device 71. The sheets stacked on the quality bill stacking device 72 are transferred to the 100-sheets sealing device 82 arranged on the lower part, and 100 sheets are sealed by a paper strap, thus a bunch H is formed.
The 100-sheets sealing devices 8 are arranged on the lower part of the stacking devices in correspondence to the stacking devices 71 and 72 and the stacking devices 73 and 74 and the sheets stacked on the stacking storages (not shown) of the corresponding stacking devices 71 and 72 by the aforementioned method are bound by a paper strap to form a bunch.
A bundle moving device 9a is arranged on the lower part of the 100-sheets sealing devices 81 to 83, and to convey the bunches H formed by the 100-sheet sealing device 8 to the next step, is composed of a conveyor and conveys the bunches H in the stacked state.
A bundle moving device (lifter) 9b receives and moves upward the bunches H conveyed by the bundle moving device 9a one by one.
The print reading device 10 reads the issue number on the uppermost surface of the bunch H conveyed by the bundle moving device 9b. The reading results are transmitted to the conveyance controller 20. When the issue number read by the print reading device 10 is a predetermined value, it is judged that the bunch H sealed by the 100-sheets sealing device 8 is normal.
The bunches H having an issue number of the predetermined value by the print reading device 10 are stacked for each 10 bunches and are transferred to the 1000-sheets sealing device 11. The 1000-sheets sealing device 11 binds the sheets stacked as 10 bunches by a paper strap and forms a bundle S. The 1000-sheets sealing device 11 includes a strap setting portion for setting paper straps, a strap feeder for feeding paper straps, a strap heater for cutting paper straps in a length suited to sealing and adhering them by heat, a winder for winding a paper strap round each 10-bunch sheets, and a pressing portion for pressing the sheets. The aforementioned process can be realized by the prior art, so that detailed explanation will be omitted.
The label issuing-attaching device 12 sticks a label printed with the sheet attributes of the kind of the bundle S, the number of sheets, and the issue location on the top of the bundle S formed by the 1000-sheets sealing device 11.
In the door opening-closing detection portion structured like this, for example, when the door 104a is closed, the detected article 104b is inserted into the detected article output and input port 104d of the door detection device 104c (hereinafter, referred to as a door closed state) and is detected. The door 104a of the sheet processing apparatus is ordinarily used in the closed state.
The operation is common to the stacking devices 71 and 72, the stacking devices 73 and 74, and the rejected bill stacking device 75.
The stacking storage of this embodiment is equivalent to the inside portion of the stacking storage cover 71b and stacks the sheets P discharged from the paddle wheels 71a.
The stacking storage cover 71b has a cover function for preventing the sheets P stacked in the stacking storage from jumping out and a security function for prevent the stacked sheets from being externally accessed and taken out easily. Therefore, the stacking storage cover 71b is locked so as not to be opened and closed when opening and closing are not permitted. Cancellation of the locking method will be explained separately in detail.
The lever position sensor 71c is a sensor for detecting the position of the lever 71e and optically detects a light shield plate 71d moving in correspondence with the vertical movement of the lever 72e. In the state shown in
Further, as a permission display to permit access to the stacking device 71, a cover opening-closing permission display lamp (a cover opening-closing permission display) 71m to permit opening and closing of the stacking storage cover 71b is installed and when the cover opening-closing permission display lamp 71m is on, the operation of opening and closing the cover of the concerned stacking portion can be performed.
When the lever 71e is in the locked state (the electromagnetic lock on state), to prevent the left end surface of the lever 71e from moving up, a stopper 71h is attracted by the electromagnetic locking device such as a solenoid and is put into the state at a position 71i1. As a result of it, the lever 71e cannot move up because the rising course direction is closed (it is put into the locked state; in the locked state, the stacking storage cover 71b cannot be opened and closed).
On the other hand, if no power is supplied to the solenoid, the stopper 71h is pulled by a spring 71j and is put into the state at a position 71j2. In this case, the lever 71e can move up and if the lever 71e moves up, the lever position sensor 71c is not shielded light by the light shield plate 71d. As a result, the lever 71e enters the unlocked state and the stacking storage cover 71d can be opened and closed.
For example, when any difficulty happens in the sheet processing apparatus (hereinafter, referred to as the main body) 100 and a condition for opening the stacking portion (for example, the stacking device 71) occurs (Y at Step S1), if any of the doors 103a to 105a of the main body 100 is opened (Y at S2), a condition for unlocking the stacking portion occurs (Y at Step S1) and when any of the doors 103a to 105a of the main body is opened (for example, the door 104a is opened), the opening of the door is detected by the door detection device 104c (Y at Step S2).
If the opening of the door is detected, to enable access (take-out, etc.) to the sheets P stacked on the stacking device 71, the electromagnetic lock is held in the unlocked state (Step S3). To notify that the stacking device 71 is in the unlocked state and can be accessed to the operator, the cover opening-closing permission display lamp 71m is turned on (Step S4).
The operator recognizes the lighting of the cover opening-closing permission display lamp 71m, opens the stacking storage cover 71b of the stacking device 71, and performs the difficulty removing operation such as removing the stacked sheets. After the operation is finished, the operator closes the stacking storage cover 71b, moves down the lever 71e, and then closes the door 104a of the main body.
If it is detected by the door detection device(the door opening-closing detection device) that the door 104a of the main body is closed (Y at Step S5), the electromagnetic lock of the stacking device 71 is turned off and the cover opening-closing permission display lamp is turned off (Step S7). As a result, the unlocking state is held in the state that no power is supplied to the solenoid.
When the condition of unlocking the stacking portion does not occur at Step S1 (N at Step S1), the door detection device confirms whether the condition of locking the stacking portion occurs or not (Step S8).
As a result of the confirmation, when a condition of locking the stacking portion occurs (Y at Step S8), the door detection device confirms whether the door of the main body is opened or not (Step S9). As a result of the confirmation, when the door of the main body is opened (Y at Step S9), the electromagnetic lock is turned on (Step S10) and the cover opening-closing permission display lamp 71m is turned off (Step S11).
The operator, when a predetermined process is finished, closes the door of the main body. If it is detected by the door detection device that the door 104a of the main body is closed (Y at Step S12), the electromagnetic lock of the stacking device 71 is turned off (Step S13) and the cover opening-closing permission display lamp is turned off (Step S14). As a result, the unlocking state is held when no power is supplied to the solenoid. After the process is finished, the process is returned to Step S1 and the sheet processing is continued.
At Step S9, the condition that the detected article 104b of the door 104a of the main body is detected by the door detection device 104d is the condition that the door is closed and this condition is hereinafter referred to as the case that the opening of the door is not detected (N at Step S9). In this case, the door detection device confirms whether the condition of locking the stacking portion is canceled or not (Step S15). As a result of this confirmation, when the condition of locking the stacking portion 71 is not canceled (N at Step S15), the process is returned to Step S9 and the opening of the door is monitored.
At Step S15, when the condition of locking the stacking portion is canceled (Y at Step S15), the process is returned to Step S1 and the sheet processing is continued.
As explained above, according to Embodiment 1 of the present invention, the power supply for the electromagnetic lock executed to ensure the security of the stacking storage cover 71b is limited to the case that the door of the main body 100 is opened, thus the power supply time of the electromagnetic lock can be shortened, so that the shortening of the life span of the solenoid and the power consumption can be reduced. As a result, the problem of “the power supply time under the electromagnetic lock is prolonged and the life span of the electromagnetic lock is shortened” described in the problem (1), the problem of “the power consumption of the apparatus is high” described in the problem (2), and the problem of “that the stacking device is under the electromagnetic lock is not known” described in the problem (3) can be solved.
For example, when a difficulty happens in the third unit 104, and the door 104a or 104b is opened, and the operation of removing the difficulty is necessary, if it is necessary to remove the sheets stacked on the stacking devices 71 and 72 installed in the fourth unit 105 or lock the stacking devices 71 and 72 to prevent mixture with sheets due to the difficulty removal operation (Y at Step S21), whether any of the monitored doors 103a to 105a of the main body is detected by the door detection device arranged so as to detect the respective doors or not is confirmed (Step S22).
As a result of this confirmation, when the door of the main body is detected (Y at Step S22), whether the opened door is a door capable of accessing the stacking devices 71 and 72 or not is confirmed (Step S23).
As a result of this confirmation, when the opened door is the door capable of accessing the stacking devices 71 and 72 (in this embodiment, the doors 104a and 104b are applicable, Step S23), the electromagnetic lock is turned on (locked) (Step S24).
If the aforementioned difficulty removal operation is finished, and the doors 104a and 104b are closed, and the closed doors 104a and 104b are detected by the door detection device 104d (Y at Step S25), the internal security of the main body is ensured, so that the electromagnetic lock is turned off (Step S26).
Thereafter, the process is returned to Step S21 and the processing of the main body 100 is continued.
At Step S22, when the opening of the door of the main body 100 is not detected (N at Step S22), whether the condition of locking the stacking portion which occurs at Step S21 is canceled or not is confirmed (S27). As a result of this confirmation, if it is not canceled, the process is returned to Step S22 and the opening of the door of the main body 100 is monitored. Further, as a result of this confirmation, when the condition of locking the stacking portion is canceled, the process is returned to Step S21 and the processing of the main body 100 is continued.
As explained above, according to the embodiment of the present invention, when the door capable of accessing the concerned stacking portion is opened, the electromagnetic lock only of the concerned stacking portion is turned on (locked) and off (unlocked) and the electromagnetic locks of other unaccessible stacking devices can be kept off, so that compared with Embodiment 1, the power supply time for the solenoid is shortened more and a higher effect can be obtained.
At Step S22, when the door of the main body 100 is opened (Y at Step S22), the door detection device confirms whether it is the door capable of accessing the concerned stacking portion or not (Step S23). As a result of the confirmation at Step S23, when it is the door capable of accessing the concerned stacking portion (Y at Step S23), the door detection device turns on and locks the electromagnetic lock of the stacking portion (Step S24).
After the processing when the door of the main body 100 is opened is finished, the door detection device detects the closing of the door of the main body 100 (Step S25). As a result of this confirmation, when the door is closed (Y at Step S25), the door detection device turns off (unlocks) the electromagnetic lock (Step S26). The reason that the door is unlocked is that similarly to the description in Embodiment 1, since the door of the main body 100 is closed, the security of the staking portion is ensured, so that if the power supply to the solenoid is stopped, not only the solenoid can be prevented from high temperature but also unnecessary power supply is avoided, so that the power can be reduced. Thereafter, the process is returned to Step S21 and the processing of the sheets P is continued.
As explained above, according to Embodiment 2 of the present invention, when the door capable of accessing the concerned stacking portion is opened, the electromagnetic lock only of the concerned stacking portion is turned on (locked) and off (unlocked) and the electromagnetic locks of other unaccessible stacking devices can be kept off, so that the power supply time for the solenoid is shortened more and a higher effect can be obtained. As a result, for the problems (1) and (2), compared with Embodiment 1, a higher effect can be obtained.
Among the same processes as those at Steps S2 to S7 indicating the processes when the condition of unlocking the stacking portion of Embodiment 1 shown in
When the condition of unlocking the stacking portion occurs (Step S31), the door of the main body 100 is opened, and when the opening of the door is detected (Step S32), the unlocking state of the electromagnetic lock of the concerned stacking portion is held and the cover opening-closing permission display lamp 71m is turned on (Step S34).
The operator confirming the cover opening-closing permission display lamp opens the stacking storage cover 71b of the stacking portion 71 (Step S35), takes out the stacked sheets, and closes the stacking storage cover (Step S36). When the stacking storage cover 71b is opened and closed, the lever sensor 71c detects that the light shield plate 71d is on (there is the light shield plate) and off (there is no light shield plate). On the basis of the detection results, it is detected that the stacking storage cover 71b is opened and closed (Step S37). If it is detected that the stacking storage cover 71b is opened and closed, the unlocking of the electromagnetic lock is held (Step S38). Then, the cover opening-closing permission display lamp 71m is turned off (Step S39).
As explained above, according to Embodiment 3 of the present invention, in addition to the effect of Embodiment 1, “Although the operator should perform the process of the stacking portion, if he does not perform it but performs the initialization, the program goes to the next process, thus the sheet processing apparatus may not be operated normally, and a difficulty may be caused” described in the problem (3) can be solved.
The present invention, when the condition of locking the stacking portion occurs, if the stacking portion is opened and closed by the operator, is an embodiment when displaying a malfunction on an operation display device 33.
The processes at Steps S21, S22, and S27 indicated in Embodiment 2 when the condition of locking the stacking portion occurs are the same as those at the steps S41, S42, and S48 of this embodiment. However, since the process after the opening of the door of the main body 100 is detected at Step S42 is different, the process of that portion will be explained below.
When the opening of any of the doors 103a to 105a of the main body 100 is detected (Step S42), the electromagnetic lock is turned on and the stacking portion is locked (Step S43). Next, the closing of the door of the main body 100 is detected (Step S44).
As a result of the detection, when the door is not closed (No at Step S44), the light shield plate 71 is detected by the lever position sensor 71c of the stacking portion and whether the stacking storage cover 71b of the staking portion is opened or not is detected (Step S45).
As a result of the detection, when it is not detected (No at Step S25), the process is returned to Step S24 and whether the door of the main body 100 or the stacking storage cover 71b of the stacking portion is opened and closed or not is monitored.
As a result of the monitoring, when it is detected that the stacking storage cover 71b of the stacking portion is opened, a warning is displayed on the operation display device 33. Namely, since the condition of locking the stacking portion occurs, the opening of the door should not be detected originally by the stacking portion, though when the operator opens it by mistake, the opening of the door is detected. In that case, a warning accompanying the malfunction is displayed on the operation display device 33.
The malfunction is monitored until the opening of the door by the main body 100 is detected (Steps S44 to S46).
As a result of the detection, when the closing of the door of the main body 100 is detected (Y at Step S44), the electromagnetic lock is turned off (Step S47). Thereafter, the process is returned to Step S41 and the ordinary process is continued.
As explained above, according to Embodiment 4 of the present invention, when the condition of locking the stacking portion occurs, the door of the main body 100 enters the open state and furthermore when the stacking storage cover 71b of the stacking portion enters the closed state, there are possibilities that an error operation may be performed by the operator, so that in this case, a warning is displayed on the operation display device 33 and care can be requested for the operator. As a result, the convenience of a manager (operator) for managing the main body 100 is improved.
When the operator presses the manual binding start switch 71h, the stacking cover 71b of the stacking device 71 is locked electromagnetically (Step S51).
Next, the sheets P stacked on the stacking device 71 are transferred to the sealing device 81 and are bound (sealed) by a paper strap (Step S52). The sealing process is displayed in the sub-routine, though it can be performed by the conventional art and it is not the object of the present invention, so that the explanation thereof will be omitted.
Next, when the sealing process is finished, the electromagnetic lock of the stacking cover 71b of the stacking device 71 is canceled and the process is finished (Step S53).
As explained above, according to Embodiment 5 of the present invention, the stacking cover 71b is prevented from opening by mistake during the binding operation, so that the injury such as device stop accompanying the malfunction described in the problem (4) can be prevented.
According to the present invention, the door condition of the sheet processing apparatus is detected, thus the power supply time of the electromagnetic lock can be shortened, so that the life span of the electromagnetic lock is lengthened, and the power consumption of the sheet processing apparatus is suppressed, and it is found that the stacking device is under the electromagnetic lock, so that the malfunction can be prevented.
