Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a mail processing device, and in particular, when the device becomes inoperable due to mail jamming during operation, the present invention speeds up the output and minimizes the downtime. The present invention relates to a mail processing device that can be used only for a long period of time.

(Prior Art) A conventional mail processing device processes mail in the order of sorting, arranging, stamping, sorting, etc. according to its functions, and these are collectively controlled.

However, individual mail items often vary in size, and during processing, they can become mechanically jammed and cause the device to stop working. In this case, all tied parts of the mail are stopped in operation near the receiving port, and those near the sending port are transported to the sorting machine and treated as errors, and then stopped.

Therefore, even though the functions operate normally except for the clogged part of the mail, all functions stop due to the common use of the drive system for each function.
In the part where processing is being executed before stopping, start again from the beginning! 1 needs to be repeated. Furthermore, even during restoration, human labor is temporarily required to remove mail items near the receiving entrance.

(Problem to be solved by the invention) The problem of the conventional technology which the invention is to solve is as mentioned above, when the mail becomes mechanically jammed, all functions stop and the mail cannot be recovered when the mail is restored. The removal work requires manpower, and the removal requires double processing of the mail that was being processed before the stoppage.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a mail processing device that overcomes the above-mentioned drawbacks.

(Means for Solving the Problem) The mail processing device of the present invention smoothes only mail pieces within a predetermined size range and sends them one by one to a first mail processing means. The mail supply means detects at least the spacing, length, and diagonal conveyance of the mail items, and sends only the mail items that are within predetermined value ranges to the fc second mail processing means, and sends out the mail items that are outside the range. The postal item that has become a postal item is returned to the previous postal item supplying means, and the second mail processing means, which operates independently of the other mail processing means, detects the presence or absence of at least a stamp and performs a predetermined process. Sends only the mail items with stamps within the predetermined size range to a subsequent sorting machine 7, and sends the mail items for which no stamps are detected within the predetermined size range to a third mail processing means;
The second mail processing means operates independently of the other mail processing means, and the second mail processing means returns postage that has fallen out of the range to the mail supply means. The mail that is not detected is turned upside down to detect the presence or absence of at least a stamp, and only the mail that has a stamp within a predetermined size range is sent to the subsequent sorter, and the mail that falls outside of that range is sent to the subsequent sorter. and a third mail processing means that returns articles to the mail supply means and operates independently of the other mail processing means.

(Example) Next, the present invention will be described in detail with reference to drawings showing examples. FIG. 1 is a block diagram showing the configuration of an embodiment of the invention, and FIG. 2 is a perspective view showing the appearance of an embodiment of the invention.

An outline of the present invention will be described below.

First, the part that processes mail is divided into several processing parts, or modules, and each of these modules is driven independently.

A removal route is provided for each processing section, or module, so that the mail removed from the sorter or detector of each processing section and the mail that is removed from the processing section at the input port side when each processing section is stopped. This method employs a method in which mail is supplied to a removal route, passes through a thickness sorter from the receiving port side, and joins a mail supply path for processing. In addition, when each processing unit, that is, one of the modules stops, its output port 11
The mail items in the processing section 111 are processed as they are and then output to the sorter.

By adopting such a method, even if one processing section is clogged with mail and stops operating, the receiving port 11
The mail items in the processing section 11 are supplied to the removal route, and are merged into the mail receiving section where the mail items are supplied from the receiving port through the thickness sorter, and then sorted in the assortment supply section.

Further, the stopped mail on the output side of the processing section continues to be processed as described above and is output to the sorting machine, and the rejected mail goes through the rejection route to the mail receiving section that supplies mail. return. At the same time, mail items are removed from the stopped processing section and cleaned, so that the system can be restored. Since the range of work required by the personnel required for this purpose is limited to the module concerned, the number of staff can be reduced compared to conventional techniques, and the recovery time is therefore extremely shortened.

Here, the structure and operation of one embodiment of the present invention will be explained.

Referring to FIGS. 1 and 2, this embodiment includes a mail supply section 1, a first mail processing section 2, a second mail processing section 3, and a third mail processing section. 4 and a sorting machine 5.

The mail supply section 1 includes a mail input section 11, a mail transfer section 12, a thickness sorter 13, and a container for over-thick mail.
=-) 14, height sorters at 6A and 16B, chutes 17A and 17B for over-height mail items, a leveling section 18, and an assortment supply section 19.

The mail received by the mail input section 11 from the input mail route 100 passes through the entire mail transfer section 12 and is supplied to a rotary drum-shaped thickness sorter 13. 15, mail pieces within a prespecified thickness range are supplied to the mail receiving section 103. Mail pieces outside the specified thickness range are fed to the overthick mail bin sheet 14 and rejected from the mail processing equipment.

The mail supplied to the transport route 102 is passed through the height sorter 16
Mail passing under the A.l 513 and within a pre-specified height range are supplied to the leveling unit 18, leveled one by one, and sent from the assortment supply unit 19 to the first level. The mail is supplied to the mail processing section 2. - 10,000, mail items outside the specified height range are fed to chutes 17A and 17B' for mail items exceeding the height, and mail items are processed 4! It
be excluded from

The first mail processing section 2 includes a length detector 21 and an exclusion route 29, and detects the length of the mail to be transferred, the interval between the mail, and the diagonal transport of the mail, The mailpieces determined to be within the size range are supplied to the second mailpiece processing section 3. Mail items determined to be outside the pre-specified size range (for example, abnormally long mail items are often sent in duplicate) are sent to Exclusion Route 2.
9, the mail is supplied to a transport route 102, reaches a mail receiving section 103, and is processed again.

The second mail processing section 3 includes a positioning device 31 and a stamp detector 3.
2 and an exclusion route 39.

In order to supply the mail to the stamp detector 32, the aligner 31 aligns the mail, detects the length of the mail and the spacing between the mail, and checks whether the mail is within a predetermined size range. Only mail items determined to be sent to the stamp detector 32. Further, mail items determined to be outside the pre-specified size range are supplied to the transfer route 102 through the rejection route 39, reach the mail receiving section 103, and are processed again. The stamp detector 32 makes a sound to detect a stamp on the mail, and when it is determined that there is a stamp, the mail is supplied to the normal transport route 42 of the third mail processing section 4, and it is determined that there is no stamp. If so, the mail is supplied to the reverse transfer route 41 of the third mail processing section 4.

The third mail processing section 4 includes a reverse transfer route 41, a normal transfer route 42, a positioning device 43, a stamp detector 45,
It also has an exclusion route 49.

Mailpieces that are determined to have stamps by the second mailpiece processing section 3 pass through the normal transport route 42, and mailpieces that are determined to have no stamps are reversed to transfer the stamps at the opposite end. In order to detect the stamps, the mail passes through the reversal transfer route 41, is aligned again by the aligner 43, is detected by the stamp detector 45, and the mail determined to have stamps is sent through the output mail route 1011. It is supplied to a sorter 5. Further, mail items for which stamps are not detected are supplied to the transfer route 102 through the rejection route 49, reach the mail receiving section 103, and are processed again. Further, in the same way as the aligner 31, the length of the mail items and the spacing between the mail items are detected, and the mail items determined to be outside the pre-specified size range are supplied to the transport route 102 through the rejection route 49. .

Therefore, if any processing section or module becomes inoperable due to a blockage of mail, the module located on the output mail route 101 side from the module will continue to operate, and all mail will be transferred to the sorting machine. 5 or to the transfer route 102 and stop the operation. In addition, in the module on the side of the mail receiving section, all the mail is supplied to the transfer route 102 and collected at the assortment supply section 18.

On the other hand, the supply from the thickness sorter 13 to the mail receiving section 103 is stopped. Therefore, when restoring the system, it is sufficient to replace only the module that has ceased to operate.

(Effects of the Invention) As explained in detail above, the present invention is divided into several processing units, that is, modules, and each module is driven independently, and each module is provided with an exclusion route, so that when an abnormality occurs, Since the mail can be removed at the same time, when the mail gets stuck in one of the modules and that module stops working, it has the effect of speeding up recovery and extremely shortening the time it takes to stop operation.
