Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a plurality of storage shelving units arranged side by side to store thin articles such as file holders (hereinafter simply referred to as file holders) that can be carried while sandwiching a document at a predetermined location. In addition, the present invention relates to a file holder delivery control device for transferring a plurality of file holders in sequence in a designated delivery order via a conveyor.

[0002]

2. Description of the Related Art Medical records in hospitals and various documents in each office are stored in a file holder storage shelf while being sandwiched between file holders, and can be taken out as needed.
Further, in the device configured to return the device to the original position when the requirement is completed, the applicant of the present invention has previously proposed a delivery control device as disclosed in Japanese Patent Publication No. 4-44881.

In this shipping control device, on the front surface of the file holder storage shelf, there is provided a carrier table which moves up, down, left, right and front and back along the same, and an address code is assigned to each file holder storage position of the file holder storage shelf. , A mark corresponding to the designated address code is attached to each file holder, and the file holder in the storage section is stored at a predetermined position of the file holder storage shelf by the automatic control of the transfer table, and the file is reversed. The file holder is taken out from a predetermined position on the holder storage shelf and discharged to the exit port.

At this time, a plurality of storage shelf units are installed side by side,
A wide transfer conveyor is arranged along the front surface of the storage rack unit, and a slide is faced to each transfer outlet on the front of each storage shelf unit so as to face the transfer conveyor. A pedestal for temporarily receiving the falling file holders in a lying state is provided, and a sensor is used to detect that there is no file holder being transferred at the conveyor conveyor position below each of these pedestals. We proposed a configuration where the file holder is tilted and the file holder is paid out to the conveyor.

[0005]

By the way, when a plurality of file holders are continuously delivered, the plurality of file holders are taken out on the downstream side of the transport conveyor in the delivery order instructed (commanded) from the terminal operation unit. It is convenient if you can, because you don't have to rearrange the file holders later.
However, when the file holders to be delivered are scattered and stored at the storage shelf units of the plurality of storage shelf units arranged side by side, the file holders are paid from the cradle of each storage shelf unit to the conveyor. It is necessary to consider the delivery timing and the delivery order of the file holders in delivery control.

For example, four storage shelf units are arranged in parallel along the upstream side to the downstream side of the transport conveyor, and the storage shelving units from the storage shelf unit at the most upstream position of the transport conveyor to the storage shelf unit at the most downstream side are unloaded. When the third, fourth, first, and second file holders are stored in the order, the first file holder in the delivery order released from the second storage unit from the most downstream to the most upstream is the most. After being transported to the downstream side along the transport conveyor at the lower portion of the receiving stand in the storage shelf unit (unit for storing the second file holder in the shipping order) at the downstream position, the shipping is placed on the receiving stand. Sequentially, the second file holder is dispensed onto the conveyor.

Next, in the storage shelf unit at the most upstream position,
At the same time as the transfer of the second file holder in the delivery order from the cradle to the transport conveyor, the third file holder in the delivery order may be delivered from the cradle of the uppermost storage rack unit to the transport conveyor. However, before the delivery order third file holder passes below the cradle in the storage shelf unit (the unit in which the delivery order fourth file holder is stored) on the downstream side adjacent to this, the delivery order fourth It is necessary to control the delivery order of the file holders and the timing of delivering the file holders from the cradle in each storage shelf unit to the transport conveyor, such that the file holders should not be delivered to the transport conveyor.

A first object of the present invention is to provide an apparatus capable of carrying a file holder in a shipping order instructed and carrying it out via a carrying conveyor. The second object of the present invention is to
In each storage shelf unit, even though there is data of the shipping order (shipping request), the number of payouts and the number of payouts below the cradle are used when paying out the file holders from the shipping section to the transport conveyor. Even if there is an error in counting the number of file holders passing through the transport conveyor, the file holders in other shipping orders are paid out and the shipping operation is continued.

[0009]

In order to solve the above problems, a file holder delivery control apparatus according to the present invention has a plurality of storage rack units, each having a plurality of file holders stored at predetermined positions, which are arranged at right and left sides. The transfer conveyors are installed along the front surfaces of the plurality of storage shelf units, and the file holders are taken over by the transfer conveyors and discharged to the respective output portions of the file holders opened at the upper front of each storage shelf unit. A transfer unit is provided so that the file holders existing in its own storage shelf unit can be output in accordance with the output order number in accordance with the command of the output terminal controller of each storage shelf unit according to the input output order number of the file holder. In the file holder delivery device configured as described above, a file passing through on the conveyor is provided near the receiving portion of each storage shelf unit. While a passage determination sensor for detecting the number of passing holders and a payout sensor for detecting the number of file holders paid out on the transfer conveyor from within its own storage shelf unit at the receiving section are provided, the exit terminal controller of each storage shelf unit Is a file that counts the delivery order storage means for storing the delivery order number of the file holders existing in its own storage shelf unit, the number of file holder passages by the passage determination sensor and the number of delivery of the file holders by the delivery sensor. A self-counter for storing the accumulated number of holders is provided, and when the delivery terminal controller of each of the storage shelving units determines that the delivery order number and the accumulated number of file holders match, the file holder that is passing at that location is displayed. If not, activate the ejection drive means in the transfer section at Of the file holder to the conveyor, and the accumulated number of file holders at the location where the file holder is discharged is incremented by 1 and stored in the self-counter, and the incremented file holder is added to the delivery terminal controller adjacent to the upstream side of the conveyor. While controlling to transfer and store the accumulated number, when the accumulated number of file holders in each of the delivery terminal controllers is different from the delivery sequence number, the file holder is not released from the transfer section and the file holder is stored in each self-counter. The total number is set and stored, and the total number of file holders is controlled to be transferred to and stored in the delivery terminal controller adjacent to the upstream side of the conveyance.

According to a second aspect of the invention, in the file holder delivery control device according to the first aspect, when at least one of the delivery terminal controllers has data of a delivery order number requested by the host controller to issue,
The self-counter provided in the delivery terminal controller at the most downstream position is monitored by a timer, and if the accumulated number of file holders at the delivery terminal controller at the most downstream position does not increment after a lapse of a predetermined time, the delivery at the upstream side It controls so that the integrated number of file holders in the self-counter of the terminal controller is incremented by one.

According to a third aspect of the present invention, in the time monitoring of the timer provided in the delivery terminal controller at the most downstream position in the second aspect, after it is judged that the first predetermined time has elapsed, the time monitoring of the timer after the next time is performed. It is controlled so that the cycle time of is shortened.

In the single delivery section 5 and the delivery section 6, the file holders F taken out by the carrier table 23 of the stacker crane 22 are discharged from the predetermined positions of the file holder storage shelves 21 to the outside of each storage shelf unit 2.

As shown in FIGS. 5 and 6, the delivery section 6 is formed in a space in which a plurality of upper and lower shelves near the front of the file holder storage shelf 21 are removed, and the delivery section 61 is provided. And an inclined passage 62 that communicates from the lower end of the delivery section 61 to the delivery port 10 of the file holder that opens to the front of each storage shelf unit 2.
A pair of left and right guide members 65, 65 are arranged at the upper end position of the carrier table 23.
The left and right side surfaces of the upper end of the file holder F inserted while being sandwiched by the pair of right and left sandwiching bodies 24, 24 are guided along the longitudinal direction thereof. Both guide members 65, 6
The front end of 5 is curved so as to be separated from each other so that the file holder F to be inserted can be easily inserted.

Further, the carrier table 23 is slidably supported by an elevating device which is vertically movable along the column 22 so as to be movable back and forth in parallel with the guide members 65, 65. Reference numeral 66 is a mounting table disposed below the pair of guide members 65, 65 and adjacent to the upper end of the inclined passage 62. The mounting table 66 is arranged in the same direction as the longitudinal direction of the guide member 65. From the bottom surface of the mounting table 66 and the crank 663 which is formed long and is rotatably supported around the front and rear end pivots 661 of the mounting table 66, and which is attached to the rotary plate of the delivery control motor 662 provided in the file holder storage shelf 21. The projecting arm 664 is connected by a link 665, and the light transmission type inventory sensor 63 shown in FIG. 5 senses that the file holder F is placed on the placing table 66, and the control motor 662 is turned on. By rotating the mounting table 66, the upper surface of the mounting table 66 is inclined toward the upper end of the inclined passage 62 and then returned to the original substantially horizontal state.

In this case, one rotation of the delivery control motor 662 tilts the mounting table 66 to drop the file holder F on a slide 71, which will be described later, and a non-contact type such as a light-reflecting type for detecting that the storage has been completed. An automatic delivery sensor 67 is provided in association with the approaching movement of the rotating link 665. On the other hand, from the exit 10 of the file holder that is open to the front of each storage shelf unit 2 at the lower end of the inclined passage 62, the slide 71 is made to face the wide endless belt-shaped transport conveyor 7 in a substantially right angle direction. The lower end of the slide 71 has frame bodies 72, 72 on both left and right sides of the conveyor 7.
Among them, the side cover plate 73 standing on the upper surface of the frame 72 on the side closer to each storage shelf unit 2 is connected to the upper end. Reference numeral 74 is a side cover plate which is erected on the side surface facing the side cover plate 73. The side cover plate 74 shields the file holder F from the slide 71 so as not to jump out from the transfer conveyor 7. Perform a function.

The file holder F which slides down along each slide 71 in a state of being laid down is a conveyor 7
It will be transferred while lying on the cradle 8 provided above. As shown in FIGS. 7 to 9, the pedestal 8 in the present embodiment has a pair of left and right support frames 81 and 82 extending from the lower end of the slide 71 along the left and right sides thereof in the direction perpendicular to the longitudinal direction of the conveyor 7. The support frames 81, 82 are L-shaped in cross section, and the horizontal plate portions of the support frames 81, 82 support the lower left and right sides of the file holder F.

One support frame 81 located on the rear side of the transfer direction of the file holder F (arrow A) by the transfer conveyor 7 is fixed across the upper portions of the left and right frame bodies 72, 72 of the transfer conveyor 7. The other support frame 82 located on the front side in the transfer direction of the file holder F by the transfer conveyor 7.
Is pivotally supported by brackets 92, 92 projecting from the left and right sides of the support base 91 of the ejection drive means 9 via pins 93, 93 so as to be vertically rotatable.

The back surface of the support frame 82 and the delivery control motor 94, which is the discharge driving means 9, are connected via a crank arm 95 and a link 96, and the support frame is rotated by one rotation of the delivery control motor 94 in the direction of arrow B. Reference numeral 82 denotes a structure in which the free end of the support plate portion 82a once pivots downward and then returns to a substantially horizontal shape as shown by the two-dot chain line in FIG. That is, the one supporting frame 82 by the discharge driving means 9
Is tilted and the file holder F supported thereby is transferred onto the transfer conveyor 7. Then, a non-contact type payout sensor 97 such as a light reflection type that detects tilting of the support frame 82 at a predetermined angle or more is provided, and it is determined that the file holder F on the receiving table 8 has been paid out to the transport conveyor 7. To do.

The pedestal 8 allows the pair of support frames 81 and 82 for supporting both sides of the lower surface of the file holder F to be rotatable with respect to each other, and connects the support frames 81 and 82 with a link (not shown). Since both support frames 81 and 82 are simultaneously turned inward by the rotation of the payout control motor 94, the file holder F placed on the support frames 81 and 82 may be dropped onto the conveyor 7. is there.

In this structure, in order to store the file holder F put in the carriage 3, a code mark attached to each file holder hanging portion of the carriage 3 and each file holder F are put in an input terminal (not shown). The code mark attached is read alternately. Next, the trolley 3 is set in the mouth of the storage section 4 on either the left or right side of the predetermined storage shelf unit 2. After that, by pressing the warehousing switch of the input terminal, the transport table 23 sequentially stores the file holders F in the carriage 3 at predetermined positions in the file holder storage shelves 21 and 21 in accordance with the controlled operation.

When the file holder F is to be taken out from the delivery section 6 for the sequential delivery section 110, the data of the necessary code is input to the operation panel of the input terminal unit, and then a removal instruction is given to the delivery section 6. Thus, for example, in the delivery section 6, the file holder F, which is taken out from the predetermined position of the file holder storage shelf 21 by the holding bodies 24 of the carrier 23, is positioned in front of the delivery section 61. Next, when the carriage 23 slidably supported advances toward the front surfaces of the pair of guide members 65, 65,
The outer edges of the file holder F on the left and right sides are guided, while the lower edge of the file holder F enters the back along the mounting table 66.

When the position detecting sensor (not shown) detects a state in which the file holder F can be placed on the placing table 66, the holding bodies 24, 24 in the carrying table 23 are separated from each other, and the file holder F stands up. Will ride on.
Switch on the contact sensor provided on the upper surface of the mounting table 66
Alternatively, when the control motor 662 is rotated with an appropriate delay after the position sensor is turned on, the mounting table 66 inclines as shown by the alternate long and short dash line in FIG. 5 and becomes substantially equal to the inclined surface of the inclined passage 62. File holder F in standing state
Slides down so that its lower end moves onto the inclined passage 62, and then transfers from the slide 71 of the exit port 10 to the cradle 8 while lying down.

Each receiving sensor 52 detects the presence or absence of the file holder F on the receiving table 8 and enters a standby state in which the control motor 94 can be turned on via the controller 51. FIG. 10 shows a functional block diagram of a control device for executing the delivery control of the file holder F of the present invention. The central controller 5 controls the driving of the transfer conveyor 7, the side conveyor 11, and the relay conveyor 101, and also inputs to instruct the file holder F stored in each storage shelf unit 2 to be delivered according to the delivery order number Fn. An apparatus (not shown) is provided and connected to the delivery terminal controllers 51a, 51b, 51c (only three are shown in FIG. 10) provided for each storage shelf unit 2 to control them.

Incidentally, in FIG. 1, the right end (the most downstream end of the conveyance)
The storage shelf unit 2 is numbered in order from No. 1 unit U1, No. 2 unit U2, No. 3 unit U3, etc.
In FIG. 10 and FIG. 11 corresponding to each other, the exit terminal controller 51a corresponding to the No. 1 unit U1 is sequentially arranged from the right end (transportation most downstream) to the No. 1 terminal T1 and the exit terminal controller 51b corresponding to the No. 2 unit U2 is the No. 2 terminal. Machine T
The delivery terminal controller 51c corresponding to the No. 2 and No. 3 units U3 is referred to as No. 3 terminal T3 and the like.

Each exit terminal controller 51a, 51b,
51c operates the stacker crane 22 to the delivery section 6 so as to take out the file holders F stored in the predetermined file holder storage shelves 21 in the storage shelf unit 2 according to the instructed delivery order number Fn. The transfer control, the operation of the delivery control motor 662 of the location delivery unit 6 corresponding to each storage shelf unit 2, the timing of transferring the file holder F on each receiving stand 8 to the delivery conveyor 7, and the like are controlled in cooperation. Do things and things.

Each delivery terminal controller 51a, 51b,
Reference numeral 51c denotes a shipping department inventory sensor 63 of each corresponding shipping department 6.
The delivery sensor 67, the receiving sensor 52 that detects the presence or absence of the file holder F on each receiving tray 8, the payout sensor 97, and the file holder F on the transport conveyor 7 have passed the locations below each receiving tray 8. While receiving signals from a plurality of passage determination sensors 53a, 53b, 53c for determining whether or not each storage shelf unit has a delivery terminal controller 51a, 51b, 51c (each terminal machine), its own storage shelf. A readable / writable memory (RA that stores the file order number Fn of the file holder existing in the unit 2 at any time
M) and the like, and a self-counter for storing the file holder integrated number SEQ obtained by counting the number Tn of file holder passages by the passage determination sensor and the number of file holders dispensed by the dispensing sensor 97. Then, as will be described later, when the shipping terminal controllers 51a, 51b, 51c of the respective storage shelf units 2 determine that the shipping order number Fn and the file holder integrated number SEQ match, it means that the vehicle is passing through that location. If there is no file holder, the discharge drive means 9 at the receiving portion at the location concerned
Is controlled to discharge the file holder to the transfer conveyor 7.

The acceptance sensor 52 is a light-reflecting non-contact sensor provided downward at the upper end of the one side cover plate 74, and the light from its light emitting portion is placed on the pedestal 8 in a lying state. When the light is reflected by the upper surface of the placed file holder F and received by the light receiving portion, a signal for determining that the file holder is present is output. Further, in the embodiment, each of the passage determination sensors 53a, 53b, 53c is a light reflection type sensor which is horizontally arranged on the inner surface of one frame 72 of the transport conveyor 7 on the upper surface of the belt. Then, the first passage determining sensor 53a is arranged on the upstream side of the conveyance below the tilting support frame 82, and the second passage determining sensor 53b and the second passage determining sensor 53c are transferred by the conveyer conveyor 7. The file holders F are arranged at a dimension interval (W2) shorter than the width dimension (W1) of the file holder F toward the downstream side in the direction (arrow A). Therefore, the three passage determination sensors 53a, 53
One of the passage determination sensors of b and 53c is ON
If so, it can be determined that the file holder F exists between the three passage determination sensors. For example, when the plurality of passage determination sensors 53a, 53b, 53c are OFF to O
If it changes to N, it can be determined that the file holder F is passing below the hanging table 8. Further, when all (three) passage determination sensors 53a, 53b, 53c are OFF, it can be determined that there is no file holder F passing below the receiving table 8. If the transfer speed of the conveyor is high, the number of passage determination sensors may be increased. In addition, when the passage determination sensor and the payout sensor are collectively referred to, a symbol Sc is used, and is referred to as a passage payout sensor.

The pass-through sensor Sc may be a non-contact sensor such as a light-reflective sensor, a light-transmissive sensor, an ultrasonic wave transmissive sensor, or a reflective sensor thereof. Next, referring to the flow charts of FIGS. 12 and 13, according to the commanded shipping order number Fn, control for shipping the file holder F in the downstream direction of the transport conveyor 7 (sequential shipping control).
Aspects will be described. Note that the flowchart of FIG. 12 is a process for the exit terminal controller 51a (= 1 terminal device T1) corresponding to the No. 1 unit U1 at the most downstream position, and the flowchart of FIG. 13 is for the units other than the most downstream unit. Processing.

As one embodiment, the file holder F having the shipping order number Fn = 3 is stored in the No. 1 unit (downstream side), and the shipping order number Fn = 1 is stored in the No. 2 unit (central position). The file holder F of No. 3 is stored, the file holder F of the delivery order number Fn = 2 is stored in the No. 3 unit (the most upstream side), and the respective delivery order number file holders F exist in the corresponding delivery section 6. However, it is assumed that the delivery section inventory sensor 63 starts in the ON state.

The first terminal T1, the second terminal T2,
In the terminal No. 3 terminal T3, the file holder integrated number SEQ and the input value INSIG. Both are set to the initial value = 1. In the flowchart of FIG. 12, first, in succession to the sequential delivery control start, in each transfer unit, the passing-and-dispensing sensor Sc is in an OFF → ON state, an ON → ON state, or OF
It is determined whether it is in the F state (step S1). When the pass-and-delivery sensor Sc is in the OFF → ON state, the file holder F is dispensed from the cradle 8 at its own transfer portion,
Alternatively, it is mounted on the transfer conveyor 7 from the upstream side and detects that the file holder F has completed passing through the portion of its own inheritance portion, and the pass-delivery sensor Sc is set to O.
When it is in the N → ON state, the conveyor 7 is conveyed from the upstream side.
It is detected that the file holder F is mounted on the. When the passing payout sensor Sc is in the OFF state, there is no passing or payout of the file holder F.

For example, to process the file holder F having the delivery order number Fn = 1 called from the delivery order storage means,
The file holder F having the delivery order number Fn = 1, which is the second terminal T2 corresponding to the second unit U2, has the highest priority,
Since the delivery control motor 662 is driven to incline the mounting table 66 of the No. 2 unit U2 and the file holder F is discharged from the delivery section 6 without any restriction,
The file holder F is placed on the receiving table 8, and then the payout control motor 94 is driven to transfer the file holder F from the receiving table 8 onto the transfer conveyor 7 to transfer it in the downstream direction. Therefore, it is determined in step S1 that the passage payout sensor Sc is in the OFF → ON state (passage start state).

In each terminal, when the receiving sensor 52 is in the OFF state (the state where the file holder F is not on the receiving table 8) in step S5 of the flowchart of FIG. Sensor 63 ON
Alternatively, when the file holder F is placed on the delivery section 6 (when it is ON), the OFF state is determined, and the delivery section 6 is released.
The step S11 of discharging more is executed.

When the file holder F is transferred to the conveyer conveyor 7 and starts to be conveyed, in step S2, the self-counter of the No. 2 terminal T2 increments (adds) 1 to the accumulated number of file holders SEQ. The accumulated number SEQ is updated. In the terminal No. 2 terminal T2, the file holder integrated number SEQ input to the self-counter and an input value INSIG. Since both are set to the initial value = 1, the updated file holder integrated number SEQ = 2 (step S2). The updated file holder integrated number SEQ = 2 is stored in the memory of the self-counter. Next, the total number of file holders S
When the EQ is changed, the same value as the changed file holder integrated number SEQ (= 2) is used as the input value INSIG.
(= 2) is output to the adjacent upstream terminal No. 3 (step S4). If there is no change in the file holder accumulated number SEQ, it is not changed.
The value of EQ is set to the upstream terminal (terminal No. 3 terminal T in the embodiment).
3) and output the same value to the input value I at the No. 3 terminal T3.
NSIG. (Step S4). Therefore,
In the memory of the terminal No. 3 terminal T3, the input value INSIG. Memorize as = 2.

After that, the No. 2 terminal T2 which has finished paying out the file holder F returns to step S1 and repeats the flow of FIG. Next, the state of the passing-out dispensing sensor Sc at the inheritance point in the most upstream No. 3 unit is determined in step S1. The third terminal T that should process the file holder F with the shipping order number Fn = 2
In No. 3, when the file holder F is not conveyed from the upstream side, that is, because there is no file holder F to pass through at the receiving portion of the No. 3 unit, step S
1 is determined to be OFF. Therefore, the input value INSIG.
= 2, on the other hand, the self-counter has the file holder integrated number SEQ = 1 as an initial value. Further, when the file holder F having the delivery order number Fn = 2 is placed on the receiving table 8, the receiving sensor 52 in step S5 is turned on.

Therefore, the judgment of the next step S6 is executed. In step S6, it is determined whether the file holder integrated number SEQ counted by the self-counter is equal to the delivery order number Fn called from the delivery order storage means. In the third terminal device T3, the delivery order number Fn = 2 called from the delivery order storage means, while the file holder integrated number SEQ = 1.
Therefore, the two values are not equal.

Therefore, in the third unit U3, step S
Without paying out the file holder F by 9, the process proceeds to step S7. In step S7, the input value INSIG. Is greater than the counted file holder integrated number SEQ (>) or other than (≦). In the above state, the input value INSIG. = 2 while the file holder integrated number SEQ = 1 (initial value), the input value is larger. Therefore, next, in step S8, the input value INSIG. The value of is substituted into the file holder integrated number SEQ. In this embodiment, the file holder integrated number SEQ is changed to 2.

Next, at step S4, the file holder integrated number SEQ = 2 is input to the upstream side with the input value INSIG. However, the third unit U3 is at the most upstream position,
Since there is no upstream storage unit, it is self-contained (input value INSI in the memory of terminal 3 terminal T3
G. = 2). When the process returns at the terminal No. 3 terminal T3 and the file holder with the delivery order Fn = 2 has not been released yet, the OFF state is detected again in step S1. When the file holder F having the delivery order number Fn = 2 is placed on the receiving table 8, the acceptance sensor 52 in step S5 is in the ON state, and therefore the determination in step S6 is executed. This time, the value of the shipping order Fn = 2 and the value of the file holder integrated number SEQ = 2 are equal, so in step S9, the file holder F is paid out and the flow from step S7 onward is repeated in the third terminal T3. .

When the file holder of the delivery order Fn = 2 is discharged at the position of the unit 3 U3, which is the most upstream position, and the carrier conveyor 7 moves downstream, the unit 2 U
Since the passing payout sensors Sc at two locations change from OFF to ON, in step S1 of the flowchart of FIG.
In the second terminal T2, the file holder integrated number SEQ = 2 is incremented (added) by 1 in step S2.
Update is performed and this value is stored in the memory of the self-counter, while the input value I is stored in the memory of the upstream terminal No. 3 terminal T3.
NSIG. = 3 and output (step S4).

In the No. 2 unit U2 and No. 3 unit U3, when the file holder F placed on the conveyor 8 is passing (step S1, ON → ON), the determination of step S7 is received. Next, referring to the flow chart of FIG. 13, the most downstream unit No. 1 unit U1
The processing at this point will be described.

As described with reference to the flow chart of FIG. 12, first, after the sequential delivery control is started, the pass-delivery sensor Sc is turned off at the transfer portion of the first unit U1.
It is determined whether it is the FF → ON state, the ON → ON state, or the OFF state (step S20). When the pass-and-delivery sensor Sc is in the OFF → ON state, the file holder F is dispensed from the cradle 8 at its own transfer portion, or
It is mounted on the transfer conveyor 7 from the upstream side and senses that the file holder F has completed passing through the portion of its own inheritance portion, and the pass-delivery sensor Sc is turned ON → ON.
When it is in the state, it is detected that the file holder F is being carried by being mounted on the carrying conveyor 7 from the upstream side.
When the passing payout sensor Sc is in the OFF state, there is no passing or payout of the file holder F.

Also, in the first terminal T1 as shown in FIG.
In step S21 of the flowchart of FIG.
When 2 is in the OFF state (the state in which the file holder F is not on the cradle 8), the ON / OFF state of the delivery section inventory sensor 63 is determined in step S22, and the file holder F is placed on the delivery section 6. When it is (when it is ON), the step S23 of discharging from the shipping section 6 is executed.

Passage payout sensor S in Unit 1 U1
When c is ON → ON (while the file holder is passing), or after executing step S23, the accumulated number of file holders in the self counter SEQ = 1 (initial value) is stored in the memory of the second terminal T2 adjacent to the upstream side. Input value INSI
G. Is output (step S24). Going back to the time when the above-mentioned file holder having the delivery order Fn = 1 is discharged, and is placed on the transport conveyor 7 and passes under the cradle 8 of the No. 1 unit U1 at the most downstream side, while the file holder F is passing, steps are taken. In S21, the ON → ON state is determined. When the passage of the file holder F is completed, it becomes O in step S21.
Determine the state of FF → ON.

Then, in step S25, the self-counter of the No. 1 terminal T1 at the most downstream position updates the file holder integrated number SEQ = 1 (initial value) by incrementing (adding) by one, and changes it. The value (= 2) of the accumulated file holder accumulated number SEQ is input to the memory of the upstream terminal No. 2 as the input value INSIG. = 2 and output (step S24). Subsequently, when the file holders in the shipping order Fn = 2 have completely passed under the receiving table 8 of the No. 1 unit U1 located at the most downstream, the accumulated number of file holders in the memory of the self-counter becomes SEQ = 3 by the steps S20 and S25. , The input value INSIG. = 3 and output (step S2
4).

In this way, the most downstream unit U
This means that the file holders of the shipping order Fn1 and 2 have passed in order below the cradle 8 of No.1. After that, the first terminal T
Self-counter file holder accumulated number SEQ in 1
When the determination in step S20 is performed again when = 3, since it is in the OFF state, it is determined in step S21 whether the sensor 52 is ON or OFF. Delivery order number Fn = 3
When the file holder F of 1 is placed on the receiving table 8, the receiving sensor 52 of step S21 is turned on.

Next, at step S26, it is determined whether the file holder integrated number SEQ is equal to the delivery order number Fn called from the delivery order storage means. In the above-mentioned state, since the accumulated number of file holders SEQ = 3 and the shipping order number Fn = 3, it is determined in step S26 that (=), and the file holder having the shipping order number Fn = 3 is conveyed from the cradle 8 to the conveyor. Payout to 7 (step S27), step S2
No. 2 terminal T which is the upstream position by executing No. 4
Total number of file holders of Terminals 2 and 3 T3 SEQ =
Rewritten to 3.

Next, in this most downstream terminal T1,
The process returns again and the determination in step S21 is executed.
When the file holder F having the delivery order number Fn = 3 is paid out to the transfer conveyor 7, the self portion (at the first terminal T1)
The payout of the file holder F by the passing payout sensor Sc is detected, it is determined from OFF to ON in step S21, the file holder integrated number SEQ is updated by (+1) (step S25), and the file holder integrated number SEQ = Four
By storing the value of and the step S24 is further executed, the file holder integrated number SEQ = 4 of the second terminal T2 and the third terminal T3, which are upstream positions, is rewritten.

In this way, the delivery order number Fn is 1,
A few file holders F could be transferred to the downstream side of the transfer conveyor 7 in the order of the delivery command. In the same manner as above, even if the three file holders F having the delivery order numbers Fn 4, 5 and 6 are located anywhere from the 1st unit to the 3rd unit, they are downstream of the transport conveyor 7 in the delivery command order. It can be received by the side.

For example, the shipping order number Fn = 5 for the No. 1 unit U1 at the most downstream position and the shipping order number F for the No. 2 unit U2.
n = 4, shipping order number F to Unit 3 U3 at the most upstream position
When n = 6 file holders are respectively stored, these files are stored in the order in which they are output in the order output section 11
Considering the control flow of releasing to 0, when the payout of the file holder F of the delivery order number Fn = 3 is completed, the accumulated number of file holders in the memory of the self-counters of all terminals becomes SEQ = 4. There is.

At the 1st terminal on the most downstream side, the shipping order number Fn
= 5 and the file holder integrated number SEQ = 4 are stored. As described above in the flowchart of FIG. 13,
Since it is determined that (≠) in the determination in step S26, the file holder having the delivery order number Fn = 5 is not paid out from the first unit U1. On the other hand, at the location of the No. 2 unit U2, the shipping order number Fn = 4, the shipping order number Fn = 4, and the aforementioned INSIG. = 4, it is determined (=) in the determination in step S9 of the flowchart of FIG. 12, and the file holder having the delivery order number Fn = 4 is paid out from the cradle 8.

Next, in the determination in step S7, the determination (≦) is made and the file holder integrated number SEQ = 4 is output to the upstream terminal No. 3 terminal T3 (step S4), and the memory of the No. 3 terminal is temporarily stored. Then INSIG. Input = 4 and memorize. When the payout file holder F is detected in step S1 of the No. 2 terminal, it is updated in step S2, and the file holder integrated number SEQ = 5. This value is output to the No. 3 terminal again (step S4), and INS is stored in the memory of the No. 3 terminal.
IG. Input = 5 and memorize. At the downstream unit No. 1, the file holder F flowing along the transport conveyor 7 is sensed by the passage dispensing sensor Sc, and the accumulated file holder number SEQ = 5.

Then, in the No. 1 terminal T1, it is judged that the delivery order number Fn = 5 is equal to the file holder integrated number SEQ = 5, and the file holder F with the delivery order number Fn = 5.
Payout (step S9), and OF of step S1
When the update is made in step S2 after the judgment of F → ON, the file holder integrated number SEQ = 6. In this way, when the value of the file holder integrated number SEQ is changed on the downstream side,
In step S4, the changed value of the file holder integrated number SEQ is sequentially output to the upstream terminal, and INSIG. The value of is changed. In the above-mentioned embodiment, INSIG. = 6.

Therefore, the file holder F having the delivery order number Fn = 6 stored in the most upstream No. 3 unit is delivered to the transport conveyor 7 from step S9 in the determination of step S6. In this way, the file holder F paid out on the upstream side is detected by the passing payout sensor Sc on the downstream side, and the value of its own file holder integrated number SEQ is also changed.

In this way, according to the present invention, even if the file holders F are delivered from the plurality of delivery ports to the receiving pedestals 8 at the respective positions substantially simultaneously along the longitudinal direction of the conveyor 7, even if the receiving pedestals 8 of the respective receiving pedestals 8 are delivered. Since the payout operation is performed by determining the approach of the file holder F transferred by the transport conveyor 7,
The inconvenience that the file holders F are vertically overlapped and transferred onto the transport conveyor 7 can be eliminated, and the file holders F can be discharged in the commanded shipping order, and the trouble of rearranging the order of the file holders on the downstream side of the transport is eliminated.

Next, the delivery control for achieving the second object of the present invention will be described. That is, in each storage shelf unit, even if there is a counting error in the number of payouts or the number of file holders passing through the transport conveyor below the cradle when paying out the file holders from the delivery section to the transport conveyor, etc. That is, the file holders in the delivery order of are delivered so that the delivery operation is continued.

For example, there may be an erroneous detection by the passing / delivery sensor Sc of the most downstream terminal device, in particular, a skipping phenomenon in which the file holder that has passed or delivered is not detected. In order to deal with such a case, each terminal is made to store whether or not there is a command of a file holder's request for leaving from the main central control unit 5, for example, the data of the order of leaving. Then, in the memory of the No. 1 terminal device T1 at the most downstream side, data including the presence / absence request data is input, including self.
In this case, if there is delivery request data in any one of the terminals, the OR condition is set to indicate that there is delivery request data.

In the flow chart of FIG. 13, the pass-and-delivery sensor Sc is OFF in the No. 1 terminal device T1 at the most downstream side.
In the case of (step S20), the acceptance sensor 52 is OF
F (step S21), and when the delivery section inventory sensor 63 in its own storage unit is determined to be OFF (step S22, OFF), step S2
At 8, it is determined whether or not there is delivery request data. If there is no delivery request data (step S28, no), there is no problem.

When it is determined that there is delivery request data (step S28, yes), it can be understood that the file holder F to be delivered is present in at least one of the storage units. Therefore, a timer (not shown) is provided in the No. 1 terminal device T1 on the most downstream side, time monitoring is executed (step S29), and if a certain time has elapsed (time up) (step S29, yes), The passing dispensing sensor S for detecting that the file holder mounted on the conveyor 7 has passed the inheritance point of the first unit.
Even if there is no change in the signal of c, the update of incrementing (adding) the value of its own file holder integrated number SEQ by 1 is executed (step S25).

Here, the lapse of a certain time (time-up) means that the file holder F placed on the transport conveyor 7 at the inheritance point of the storage unit (No. 3 unit U3 in the embodiment) at the most upstream position is the most downstream inheritance part. It means the time to complete passing through. As described above, when the predetermined time elapses, it is determined in step S25 that the own file holder integrated number SE
The value of Q is forcibly updated, and the value increased by 1 is stored in the memory of the upstream terminal (terminal No. 2 terminal U2 in the embodiment) INSIG. 12 is activated, the control flow of FIG. 12 in the upstream terminal operates, and if there is a file holder, it pays out, and if there is no file holder, it moves to the upstream terminal and controls it. The transfer operation can be continued, such as activating the flow.

When the time is not up in step S29, it can be determined that the file holder has passed at the inheritance point in the most downstream unit, so the count (timekeeping) of the timer may be reset and updated (step). S30). That is, when there is a file holder to be delivered to at least one of the storage units including its own storage unit, the payout should be executed without fail, and nevertheless, the above-mentioned fixed time has elapsed. That is, it means that the skipping sensor Sc in any of the storage units has skipped reading without counting the file holders on the conveyer conveyor 7. Therefore, in this case, when a certain time elapses, the step S25 is performed. Forcibly update the value of own file holder accumulated number SEQ, and
The value increased by the same is stored in the memory of the upstream terminal (terminal No. 2 terminal U2 in the embodiment) as INSIG. It is input as the value of and the leaving operation is continued.

If the payout passage sensor Sc is in the OFF → ON state in the No. 1 terminal T1 at the most downstream position (step S20), the value of its own file holder integrated number SEQ is forced in step S25. And the value increased by 1 is stored in the memory of the upstream terminal (terminal No. 2 terminal U2 in the embodiment) as INSIG. Input as the value of. Further, in step S21, the acceptance sensor 52 is OF
When the file holder F is in the F state (the state where the file holder F is not present on the cradle 8), the ON / OFF state of the delivery section inventory sensor 63 is determined in step S22, and the file holder F is placed on the delivery section 6. At this time (when it is ON), step S23 of discharging from the delivery section 6 is executed, and if the acceptance sensor 52 is in the ON state in step S21, then in step S26, the delivery order number Fn and the file are output. If the accumulated number of holders SEQ is equal to (=), the file holder F is paid out in the pedestal 8 (step S27).

Next, referring to the flow chart of FIG. 14, when the passing / delivery sensor Sc in the storage unit at any of the above positions double counts the file holders on the transport conveyor 7, that is, each storage rack In the unit, if there is a counting error of counting one file holder twice among the counting errors of the number of passing file holders, except for the file holder that was not paid out, the file holders in the other delivery order are That is, the delivery operation is continued as it is paid out.

In the flow chart of FIG. 14, the payout passage sensor Sc is OFF (step S40) and the acceptance sensor 52 is OFF in the No. 1 terminal device T1 located at the most downstream side.
(Step S41) In addition, when it is determined that the delivery section inventory sensor 63 in its own storage unit is OFF (step S42, OFF), step S4.
At 3, it is determined whether or not there is delivery request data. If there is no delivery request data (step S43, no), there is no problem.

When it is determined that there is delivery request data (step S43, yes), it can be understood that the file holder F to be delivered exists in at least one of the storage units. It is determined whether or not the time-up has occurred (step S44), and if yes in this step S44, it is determined whether or not the time-up is activated for the first time (step S45).

Similarly, the payout passage sensor Sc is turned off.
Even in the ON state (step S40), it is determined whether or not the time-up is activated for the first time (step S4).
5). As described above, when the payout passage sensor Sc in any one of the terminals has a double count, when the payout passage sensor Sc at the most downstream position is counting the predetermined number of passing file holders, the time elapses. However, since only one less number can be counted, as described above, the file holder F mounted on the transport conveyor 7 at the inheritance position of the storage unit (No. 3 unit U3 in the embodiment) at the most upstream position determines the most downstream inheritance part. If the time until the passage is completed elapses, a certain time elapses (time-up) (step S
44). And once the time is up (step S
45, yes) and insert n in the timer value of the cyclic timer to set the waiting time for time monitoring to be short (step S
46), forcibly updating the value of its own file holder integrated number SEQ in the most downstream terminal T1 (step S
47), the value increased by 1 is stored in the memory of the upstream side terminal (terminal No. 2 terminal U2 in the embodiment) as INSIG. It is input as the value of and the leaving operation is continued (step S48).

With this arrangement, the payout passage sensor Sc
Even if the file holder that should be issued is not paid out due to a double counting error, the file holders in the other shipping orders are paid out except for the file holder that was not paid out It can be continued. Since the file holders that have not been paid out are paid out later, the delivery order of this part will be out of order.

When the time is up for the first time (step S
45, no), the timer is initialized (step S49), and the time required for the elapse of the predetermined time (time-up) is the same as the first time. If it is determined in step S44 that the time has not expired, it can be determined that the file holder has passed at the inheritance point in the most downstream unit, so the count (clocking) of the cyclic timer is reset and updated. Good! (Step S5
0).

In step S41, the acceptance sensor 52 turns off.
In the N state (the state in which the file holder F is on the cradle 8), it is determined whether or not the value of the own file holder integrated number SEQ in the most downstream terminal T1 and the delivery order Fn match (step S51). If they match, the file holder F may be dispensed from the cradle 8, and if they do not match, the determination in step S44 is received. Further, the receiving sensor 52 is turned off (the file holder F is placed on the receiving stand 8).
When there is not any), it is determined that the delivery section inventory sensor 63 in its own storage unit is ON (step S4).
2, ON), the file holder may be discharged from the delivery section in step S53.

[0072]

As described above, according to the first aspect of the present invention, a plurality of storage rack units having a large number of file holders stored at predetermined positions are arranged at right and left sides, and the plurality of storage units are stored. A transfer conveyor is arranged along the front surface of the shelf unit, and a transfer section for transferring the file holder to the transfer conveyor and discharging the file holder is provided at each delivery section of the file holder opened at the upper front surface of each storage shelf unit. A file holder configured to issue the file holders existing in its own storage shelf unit according to the output order number of each storage shelf unit according to the output order number of the file holder. And a passage determination device that detects the number of passing file holders on the transfer conveyor near the receiving portion of each of the storage shelving units. Sensor and a pay-out sensor that detects the number of file holders that are paid out from the storage shelf unit on the transfer conveyor to the storage terminal unit of each storage shelf unit. A delivery order storage means for storing the delivery order number of the file holders existing in, and a self-counter for storing the file holder integrated number obtained by counting the number of file holder passages by the passage determination sensor and the number of file holders delivered by the delivery sensor. When the delivery terminal controller of each storage shelf unit determines that the delivery order number and the integrated number of file holders match, if there is no passing file holder at that location, the transfer portion at the location is The ejection drive means is activated to eject the file holder onto the transfer conveyor, and The file holder integrated number at the location where the file holder is released is incremented by 1 and stored in the self-counter, and the incremented file holder integrated number is transferred and stored in the delivery terminal controller adjacent to the upstream side of conveyance. On the other hand, when the cumulative number of file holders in each shipping terminal controller is different from the shipping sequence number while controlling, the file holder cumulative number is set and stored in each self-counter without discharging the file holder from the transfer section, and The accumulated number of file holders is controlled to be transferred to and stored in the delivery terminal controller adjacent to the upstream side of conveyance.

Therefore, even if there are a plurality of storage rack units along the direction in which the file holders are conveyed by the conveyor, the presence or absence of the file holders approaching the cradle is detected by the passage determination sensor at each inheritance point, and they approach each other. If there is no file holder, the transfer unit moves the file holder onto the transfer conveyor, and if there is an approaching file holder, the drive means is controlled so that the transfer unit is operated after the file holder is overrun. Under the condition that the phenomenon of overlapping file holders does not occur,
The file holders can be released in the order in which they are ordered.

Then, the cumulative number of file holders at the location where the file holder is released is incremented by 1 and stored in the self-counter, and the incremented cumulative number of file holders is transferred to the delivery terminal controller adjacent to the upstream side of conveyance. On the other hand, when the cumulative number of file holders in each of the shipping terminal controllers is different from the shipping sequence number, the file holders are not discharged from the inheritance unit and the cumulative number of file holders is set in each self-counter. Are stored and stored, and the accumulated number of file holders is controlled to be transferred to and stored in the delivery terminal controller adjacent to the upstream side of the conveyance, so that a plurality of delivery terminal controllers arranged in parallel operate in cooperation with each other. And the probability of malfunctioning is low, The effect of being able to reliably control the order in which the folders are delivered and the timing of delivering the file holders from the cradle to the transport conveyor in each storage shelf unit, and discharging the file holders to the downstream side of the transport conveyor in the order of delivery Play.

The invention according to claim 2 is the same as claim 1.
In the file holder outgoing control device described, when at least one of the outgoing terminal controllers has data of the outgoing sequence number requested by the host controller, the self-counter provided in the outgoing terminal controller at the most downstream position is used as a timer. If the cumulative number of file holders in the exit terminal controller at the most downstream position does not increment after a predetermined time has elapsed, increment the cumulative number of file holders in the self-counter of the exit terminal controller on the upstream side by one. It is controlled to do so.

As a result, when at least one of the shipping terminal controllers has data for a shipping request, the file holder should be counted by the self-counter at a predetermined position when the file holder is placed on the transport conveyor for a certain time. However, if the count is missed, the self-counter at the most downstream position is forcibly incremented by 1 after the elapse of the certain period of time, so that the plurality of terminal controllers can be continuously operated and the count error causes It is possible to prevent the interruption of the sequential shipping control.

According to a third aspect of the present invention, in the time monitoring of the timer provided in the delivery terminal controller at the most downstream position in the second aspect, after it is judged that the first predetermined time has elapsed, the time monitoring of the timer after the next time is performed. It is controlled so that the cycle time of is shortened. In the case of double counting among the count mistakes, the file holders in the subsequent order are erroneously determined to have been paid out, so that the normal shipping control makes the subsequent shipping operation impossible. Therefore, in the time monitoring of the second time or more, the time monitoring time by the timer is shortened so that the time-up occurs quickly, the release of the file holder that has not been paid out is postponed, and the delivery work is continued. The effect of being able to reduce the effect of counting errors is achieved.
