Description

[Detailed Description of the Invention] The present invention relates to an improvement in an automatic mail sorting machine that reads the postal code written on the mail and automatically sorts it into each sorting box.

It is well known that automatic mail sorting machines are widely used, which read the postal code written on mail, sort and transport the mail based on the reading information, and guide and stack the mail in designated sorting boxes. .

However, in this type of sorting machine, when the sorting box is full of mail, the mail must be manually or mechanically removed from the sorting box and subjected to processing such as sub-sorting or delivery sorting.

If reading and sorting operations are not continued during this retrieval, the processing capacity will be reduced.

However, even during extraction, a new reading classification is performed,
Of course there is mail to be directed to that sorting box.

Since this mail cannot be directly introduced into the sorting box, the conveyance must be temporarily stopped in front of the sorting box and must wait until the removal is completed.

Therefore, the processing efficiency is low, and the control of the conveyance system is complicated, resulting in high cost.

Therefore, a structure was devised in which a small auxiliary sorting box was installed near each sorting box, and the mail was introduced into the auxiliary sorting box during removal.

However, in this case, the device becomes larger and requires more space for installation.

In addition, a device was developed in which a dedicated reject box was installed and everything was introduced into the Reject I box during removal to make the device more compact, but the items inside the Reject I box were put back into the device and recycled. Must be read and reclassified.

Therefore, it is time-consuming and leads to a decrease in processing capacity.

Furthermore, one of the sorting boxes is left as a spare sorting box, and when a predetermined sorting box becomes full, the mail to be guided to that sorting box is designated as the spare sorting box and introduced, Clear the address designation on the box and use it as a spare sorted box.

There is an idea that the above-mentioned preliminary sorting box is a sorting box with a new destination specified.

However, in this case, the arrangement state of the sorting boxes constantly changes, and it is quite difficult for the operator to constantly grasp the state, making it inappropriate to take out the boxes manually.

The present invention was developed based on the above-mentioned circumstances, and its purpose is to provide a loop-shaped auxiliary conveyance path to guide the mail to be guided to the sorting box being taken out. The present invention aims to provide an automatic mail sorting machine that can increase processing capacity.

An embodiment of the present invention will be described below based on the drawings.

1 in the figure is the main body of the sorting machine, and in the negative corner of this
. . . A supply section 2 into which the .

Adjacent to the supply section 2, a postal code reading section 3 consisting of, for example, an optical character reading device is provided.

On the other hand, the sorting machine main body 1 is provided with a sorting section 5 consisting of a large number of sorting boxes 4 divided into a plurality of rows and columns.

Each division box 4 corresponds to a postal code (-provided for each destination).

The postal code reading section 3 and the sorting section 5 are connected by a conveyance path 6 for conveying the mail P.

In other words, the conveyance path 6 extends upward from the reading section 3, and its midway portion is connected to the sorting boxes 4 of each stage of L"'F.
The conveyor path branches and extends horizontally toward . .

A gate 7 is provided at each branch position of the conveyance path 6, and the timing is determined based on the signal from the reading section 3 so that the There is.

An auxiliary conveyance path 8 is connected to a midway portion of the conveyance path 6 constructed in this way, that is, at the intermediate point where it first diverges from the reading section 3 .

This preliminary conveyance path 8 is curved into a loop shape at the −F side portion of the dividing portion 5 .

An auxiliary gate 1-9 is provided at the connection station with the conveyance path 6, which moves in synchronization with the timing based on the signal from the reading section 3. Drive control is performed based on signals from sensing bodies (not shown) provided in the sorting boxes 4, respectively.

Then, the postal items P input into the supply section 2 are taken out one by one and fed into the postal code reading section 3, where the postal code is read.

Normally, the auxiliary gate 9 opens the auxiliary transport path 8, and the mail P whose postal code has been read is guided to the transport path 6.

Each gate 7... is rotated and displaced in accordance with the signal from the reading section 3 and in accordance with the conveyance of the mail P.

Therefore, the mail P is led to and accumulated in a designated sorting box 4 according to its destination.

When any of the sorting boxes 4 becomes full, a signal is emitted from a detection body (not shown), and the mail P must be taken out manually or mechanically.

The sensing body also sends a signal to the reading unit 3 to store it.

The sorting process continues as it is, when the reading unit 3 confirms that the navy blue (to be continued, the postal item ■ to be led to the sorting box 4 being taken out) is sent to the auxiliary gate 9 and the auxiliary transport path 8.

The auxiliary game 1-9 rotates and displaces with proper timing, and guides only the mail P to the auxiliary conveyance path 8 that runs endlessly.

The preliminary conveyance path 8 conveys the mail P as indicated by the broken line arrow in the figure and waits for the completion of the retrieval operation.

Note that since the auxiliary game 1-9 immediately returns to its original position, the mail P other than the one being led to the sorting box 4 during the extraction operation...
. . . are all guided to a conveyance path 6 and accumulated in a designated sorting box 4.

Therefore, the sorting process continues without any stagnation.

When the detection body detects the completion of taking out, it sends a signal to the auxiliary gate 9 again, and sends the mail P on the auxiliary conveyance path 8 to the conveyance path 6.

The mail P is guided to a designated sorting box 4 by a game h7 which rotates in response to a stored signal from the reading section 3.

Further, the preliminary conveyance path 8 accompanies the conveyance of the waiting mail P until it is sent.

As explained above, according to the present invention, a loop-shaped auxiliary conveyance path is connected to the conveyance path that guides the conveyance of postal items whose postal code has been read to a designated sorting box, and the mail is transferred from a full sorting box to a designated sorting box. If there is mail that should be guided to the sorting box while it is being taken out, it is guided to the above-mentioned auxiliary conveyance path and kept waiting, so that while taking out the sorted mail from the full sorting box. Even if the original sorting process is carried out, the original sorting process will not be stopped at all, and the process efficiency can be improved.Moreover, its configuration is simple, and there is no need to expand the installation space, making it an inexpensive postal service. We can provide automatic object sorting machine.
