The FF circuit is supplied to the control circuit 67, and the set output of the FF circuit 74 is supplied to the control circuit 57 as a signal indicating that the mounting table 44 is at the full position of the mail pieces A. I'm here.

FIG. 6 schematically shows the electrical circuit of the entire system. That is, the converting section 81 converts the postal code read as a result of reading-4 into the classification code of the accumulating section 10 corresponding to the postal code. The output of the conversion section 81 is supplied to the control section 33, and the control section 43 has the integration section 10. . . . and various signals from the preliminary accumulation section 100, such as a push-out enable signal, a full signal, an initialization end signal,
An operation stop signal, empty detection signal, etc. are supplied.

When the control unit 33 determines that the container is ready for extrusion based on the supplied extrusion enable signal, or determines that it is full based on the full signal, and an empty detection signal is supplied from the corresponding stacking unit 10. , outputs a pushing signal to the stacking section 101fC, and also controls the sorting of the corresponding mail A according to the sorting code supplied. Further, when the sorting code of a certain stacking section 10 is supplied within the extrusion time of a certain stacking section 10, the control section 33 performs sorting control to stack the corresponding mail A in the preliminary stacking section 100, and the extrusion When the accumulating section 10 is in its initial state, a pushing signal is output to the preliminary accumulating section 100.

Furthermore, the control section 33 controls the upper stacking section 10 when the sorting operation is started by inputting a sorting start key (not shown).・

When the initialization end signal is supplied from 0, the initialization signal is output to each of the lower stacking units 10, . . . , 100 starts the ejecting operation of the ejecting section 2 when an initialization end signal is supplied from the extractor 100. Further, the control section 33 determines whether to stop the operation based on the supplied operation stop signal, and stops the take-out section 2 and also stops the conveyance of the mail items A on each conveyance path. Note that the above-mentioned stacking sections 10 of each stage...
100 are connected to the control unit 33 by bus drivers 83, 84, and 85, respectively.

Next, the operation in such a configuration will be explained. For example, now, mail 1 person A that has been set in the supply section IK is sequentially taken out by the take-out section 2 and conveyed on the taking-in conveyance path 3, and the postal code given to the mail person by the reading section 4 during the conveyance. is read. Then, the read postal code is converted into a classification code by the conversion section 81 and supplied to the control section 33. For your convenience, the control section 33 performs conveyance control and sorting control so that the mail A is accumulated in the corresponding accumulation section 10 according to the sorting code. The mail items A are accumulated in the accumulation unit 10VC corresponding to the postal code assigned to the mail person.

In this way, when the mail A is supplied to a predetermined stacking section 10 and a predetermined number of one mail person is placed on the mounting table 44, the detector 69 detects the mail A, and this detection By driving the control circuit s';rilt motor 55 in the forward direction in response to the signal, the loading table 44 is lowered by a distance corresponding to a predetermined number of mail pieces A. works as above. In this way, when the plurality of mail items A... are supplied, the mounting table 44 descends to the ejectable position before being full, and the ejectable full detector 61 is turned on, and the FF circuit 73 is set. . This FF
Based on the outputs of the circuit 73, the control circuit 57 outputs an extrusion enable signal and lights up the operating indicator 66.

As a result, when the control section 33 receives an empty detection signal from the corresponding accumulation section 100 control circuit 67, it outputs a push signal to the accumulation section.

Then, the control circuit 5r drives the motor 55 in the forward direction to lower the table 44, stops the motor 66 by the detector 4 of the lower limit detector 63, and drives the motor 42 in the forward direction. K, place the extrusion part 40 on the mounting table 44.
It moves forward along the longitudinal direction. As a result, the mail group A1 . When this transfer is completed, a detection signal is output from the detector 48 by the protrusion provided on the bottom 40c of the extrusion section 40. Then, the control circuit 51
The mounting table 44 is moved by driving the motor 56 in the opposite direction.
At the same time, by driving the motor 42 in the opposite direction, the extrusion section 40f is moved back along the longitudinal direction of the mounting table 44. Thereafter, when the mounting table 44 reaches the initial position, the upper limit detector 60 detects this, and the control circuit 57 stops the motor 65. 9. When the push-out section 40 reaches the pJ period' position, a detection signal is output from the detector 46 by the protrusion on the bottom 40e of the push-out section 40, and the control circuit 61 stops the motor 42t. In particular, the extruder 40 is stopped. At this time,
The control circuit 57 turns off the indicator 66 during operation.

Further, it is assumed that the extrusion signal is not supplied from the control unit 33 between when the extrusion possible and full detector 61 is turned on until it is turned off. Then, pushing is possible, the full detector 61 is turned off, the FF circuit 74 is set, and the control circuit 51 outputs a full signal according to the set output of the FF circuit 74.

The control section 33 then controls the control circuit 57 of the corresponding integrated section 10.
When the empty detection signal is supplied, the pushout signal 46 is output to the accumulating unit 10.Thus, in the accumulating unit 1o, the control circuit 62 drives the motor 56 in the forward direction. The mounting table 44 is lowered. Thereafter, by operating in the same manner as in the case of transferring the mail items A1 before being full, the mail items A1 and the stacking section 10 that are full are transferred.
... are transferred to the corresponding tray 15.

Also, within the extrusion time of the accumulating unit 10, the accumulating unit 10
When the classification code of is supplied to the control section 33, the control section 33
performs sorting control so that the corresponding mail A is accumulated in the preliminary accumulation section 100.

Further, other postal acquaintances are also accumulated in the corresponding accumulation section 10. Then, when the stacking section 10 finishes pushing out and returns to the state where it can be stacked, the mail A corresponding to the stacking section 10 is stacked again.

Further, at 9 o'clock after the accumulation section 10 returns, the control section 33 outputs a pushing signal to the preliminary accumulation section 100. Accordingly, in the preliminary accumulation section 100, the control section 11 drives the motor 66 in one direction, thereby lowering the table 44. From then on, it will operate in the same way as when transferring the postal acquaintance before it was full.
The collected mail items A, . . . in the preliminary stacking section 100 are transferred to the corresponding trays 15.

Next, in a state in which the switching switch and cheer 1 of each of the accumulation sections 1o..., 100 are turned on in advance and outputting a logic 6o'' signal, if an accumulation abnormality occurs in a predetermined accumulation section 10, 100, Suppose that the operator discovers the abnormality in the stacking section and indicates the lower i of the mounting table 44 using the mounting table up/down switch or the roller 7, or that the control circuit 57 interrupts the accumulation abnormality in the stacking section.

Then, the control circuit 57 lowers the mounting table 4-4 by driving the drive/IF pulse motor 55 to a square vortex, and also turns off the operating indicator 65 and blinks the abnormality indicator 66. At this time, the control circuit 5r
sets the FF circuit 15 and outputs an operation stop signal to the control section 33. Then, the control unit 33 determines to stop the drive, stops the take-out unit 2, and stops the conveyance of the mail A by each conveyance path.

Then, the operator/author is the above-mentioned predetermined accumulation unit 1o...

After canceling the accumulation abnormality in 100, press the classification start key (
(not shown). Then, the control section S3 connects the above-mentioned accumulation sections 10...#10 via the path drivers 83 to 86.
Initialization signals are output sequentially for 0. Accordingly, when the set output of the FF circuit 15 is the 111 signal, the control circuit 67 of the integrated unit 10 .
At the same time, by driving the motor 42 in the opposite direction, the extrusion section 40 is moved back along the longitudinal direction of the mounting table 44. Then, the mail item A on the mounting table 44
When the top surface of the mail detector 59 is detected, the control circuit j7 stops the motor 55. Next, the control circuit 5
7 is a mounting table 4 for driving the motor 56 in the forward direction.
4 by a distance corresponding to the optimal location for collecting postal acquaintances. In addition, 1, due to the rise of the mounting table 44, the mounting table 44
When the motor reaches the initial position, the upper limit detector 60 detects this, and the control circuit 57 stops the motor 65. On the other hand, when the extrusion part 40 reaches the initial position, the detector 46
A detection signal is output from the control circuit 57 and the control circuit 42 is stopped, thereby stopping the extrusion section 40. As a result, the control circuit 67 controls the FF circuit 75 when the mounting table 44 and the push-out section 40 reach the initial position or the optimum position.
t-reset and sends the initialization end signal to the control unit 3.
Output to 3. Further, when the control circuit 67 is supplied with the initialization signal, the upper limit detector 60 detects that the roll mounting table 44 is at the initial position, and the detector 46 causes the push-out portion 40 to be pushed out.
is detected to be the initial position, or F
When the set output of the F circuit 75 is a 1'01 signal, an initialization end signal is output to the control/hook section 33.

When the control unit 33 is supplied with the initialization completion signal, it drives the take-out unit and each conveyance path, thereby
Start sorting operation.

Also, a switch for switching each of the stacking units 10 . . . , 100 .

While the chia 6 is turned off in advance and is outputting the logic ``''1'1'', the operator discovers that a stacking abnormality has occurred in the predetermined stacking section 10°100, and stops the lowering of the mounting table 44. It is assumed that an instruction is given by the up/down switch 67 or that the control circuit 57 determines that there is an abnormality in the integration. Then, the control circuit 57 drives the driving nose motor 55 in the forward direction, thereby lowering the mounting table 44f, turning off the operating indicator 65, and blinking the abnormality indicator 66t. Further, at this time, the control circuit 52 outputs an operation stop signal to the control section 33. Then, the control unit 33 determines to stop the drive, stops the take-out unit 2, and stops the conveyance of the mail A by each conveyance path.

Then, the operator selects the predetermined accumulation section 10 .

After canceling the accumulation abnormality at 100, a classification start key (not shown) is turned on. Then, the control unit 33 controls each of the upper stacking units 10 . . . , ioo sequentially outputs initialization signals. Accordingly, the integration unit 10 which received the initialization signal. ..., 1000 control circuit 6
7 determines initialization based on the fact that "1#" is supplied from the OR circuit 76, and raises the mounting table 44 by driving the motor 55 in the opposite direction.

Then, when the upper surface of the mail piece A on the mounting table 44 is detected by the mail piece detector 59, the control circuit 57 stops the motor 55. Next, the control circuit 57 controls the motor 55.
By driving in the forward direction, the mounting table 44 is lowered by a distance corresponding to the optimal position for collecting the mail pieces A. Furthermore, when the mounting table 44 reaches the initial position due to the rise of the mounting table 44, the upper limit detector 60 detects this, and thereby
Control circuit 57 stops motor 65. Furthermore, the control circuit 57 drives the motor 42 in the opposite direction) to cause the extrusion section 40 to move backward along the longitudinal direction of the mounting table 44. Thereafter, when the extrusion part 40 reaches the initial position, the protrusion on the bottom 40e of the extrusion part 40 causes the detector 46
A detection signal is output from the control circuit 57, and the control circuit 57 stops the extrusion section 40 by stopping the motor 42. As a result, the control circuit 57 outputs an initialization end signal to the control section 33 when the mounting table 44 and the extrusion section 40 reach the initial position or the optimum position. Further, when the control circuit 57 is supplied with the initialization signal, the upper limit detector 60 is set on the mounting table 44.
If the detector 46 detects that the push-out section 40 is at the initial position, an initialization end signal is output to the control section 33 .

The control section 33 controls all the accumulation sections 10...

When an initialization end signal is supplied from 100, the extraction section 2 is driven to start the sorting operation.

As mentioned above, after the sorting operation is stopped due to accumulation abnormality, etc.
When starting the sorting operation, selectively all accumulators 1
0..., 100 or an abnormality has occurred.The mounting table and extrusion part of only the hole accumulation part are set to the initial position or the optimum position, and then the actual sorting operation is performed.
Even if there is a stacking section in which the loading platform or the extrusion section is moved manually when the sorting operation is stopped, the stacking on that stacking section can be performed normally.

In addition, since initialization is performed at the start of sorting only for the stacking unit where a stacking error has occurred or the stacking unit where the table up/down switch has been turned on, power consumption is low and the motor of each stacking unit can be driven. It is better to use a transformer with a smaller input power supply capacity.

In the above embodiment, the initialization is stored in the FF circuit, but the invention is not limited to this, and the initialization flag can be set in the memory in the control circuit by program control. Also good. Further, although the switching is performed using the changeover switches in the accumulation section, the control is not limited to this and may be performed by changing the control from the control section.

[Effects of the Invention] - As described in detail above, according to the present invention, even if the placing table and push-out part in a predetermined stacking section are not in the appropriate stacking position due to manual operation when stopping during sorting, It is possible to provide a sorting machine with an automatic take-out device that can prevent the accumulation tool from failing when sorting and accumulation is performed again.
