Description

[Detailed Description of the Invention] This invention relates to an automatic sorted letter accumulation device that accumulates letters sorted by destination in a letter accumulation room by destination.

2. Description of the Related Art There is a conventional automatic stacking device for sorted letters as shown in FIG. In other words, a in the figure is a letter section with a large number of address-specific letter collection chambers b... inside this letter section a, and a plurality of preliminary letter accumulation chambers c are further arranged at the bottom of the letter section a. has been done. Further, d in the figure is a letter supply section, in which a letter sorting device consisting of an optical reader and a letter conveying mechanism (not shown) is housed. Then, the address of the letter e is read by an optical reader, and the letter is further conveyed to the letter sorting body a by the letter conveyance mechanism according to the destination. Then, the further conveyed letters e... are conveyed along the letter conveyance path f... to the letter accumulation rooms b... for each destination, and each letter accumulation room b...
accumulated within. At this time, for example, when letter collection room b at a certain destination becomes full,
The stacking in the letter accumulating chamber b is stopped, and the subsequent letter e... is conveyed along the letter conveying path g by the letter conveying mechanism so that it is accumulated in a standing position in the preliminary letter accumulating chamber c. It's summery.

However, a large number of letters to the destination e.
... are once accumulated in the letter accumulation chamber b of a predetermined destination via the letter conveyance path f..., and when this letter accumulation chamber b becomes full, a separate letter conveyance path f. Subsequent letters e... are stacked into the preliminary letter accumulation chamber c via the letter conveyance path g, and in an upright position different from the stacking form of the letters e... accumulated in other letter accumulation chambers b... Therefore, it is extremely troublesome to take out the accumulated letters, resulting in problems such as poor operability in taking out the letters. Moreover,
Subsequent letters e after the letter collection room b is full
... are conveyed by an independent letter conveyance path g, resulting in a problem that the structure becomes extremely complicated.

This idea was made based on the above circumstances, and its purpose is to convert one or more of the letter stacking chambers in which letters are stacked horizontally into a large letter stacking room with a larger letter stacking capacity than the other letter stacking chambers. Then, in this large letter accumulation room, letters from large destinations with a large amount of letters accumulated are stacked horizontally in the same manner as letters stacked in other letter accumulation room groups, and the large letter accumulation room and letter accumulation room It is an object of the present invention to provide an automatic stacking device for sorted letters that can improve the operability of stacked letters in groups and simplify the structure.

An embodiment of this invention will be described below with reference to FIG. In the figure, reference numeral 1 denotes a letter sorting unit of an automatic sorted letter stacking device, and a large number of letter stacking rooms 2 for each destination are arranged inside the letter sorting unit. These letter accumulation chambers 2 are arranged in five upper and lower stages and are arranged in parallel along the longitudinal direction of the letter section 1, forming a letter accumulation chamber group 2a. Furthermore, within this letter section 1, there are a plurality of large letter collection rooms 3 for each destination.
...is arranged. This large letter collection room 3...
are formed to have a capacity that satisfies the number of letters 4 to be accumulated at each destination, and are arranged in parallel at the bottom of the letter section 1. These large letter accumulation chambers 3 form a large letter accumulation chamber group 3a. Further, numeral 5 in the figure is a letter supply section, inside which a letter sorting device consisting of an optical reader and a letter conveyance mechanism (not shown) is installed.
It is provided on the side of the letter segment 1.

In addition, 6 in the figure is a letter conveyance system consisting of a letter conveyance path 8 which guides the letters 4 ... supplied from the letter supply unit 5 to each letter accumulation room 2 . 4... to the letter conveyance path 8 of each stage, and the letter conveyance path 8 of each stage.
Accumulation chamber gates 10 for guiding letters 4 from... to each letter accumulation chamber 2 are provided.

Therefore, when stacking the letters 4... using the automatic stacking device configured in this way, the letters 4...
The postal code written on the letter 4... is read by an optical reading device, and then the letter 4... is conveyed to the letter sorting body 1 by the letter conveying mechanism according to the destination of the postal code. Then, the further conveyed letters 4... are guided to the letter conveyance paths 8 of each stage by the pass gates 9..., and then the stacking room gate 1
0..., and are sequentially accumulated in a horizontal state in letter accumulation rooms 2... specified for each destination and large letter accumulation rooms 3... specified for each destination. Through this series of operations of the automatic stacking device, letters 4 are sorted and stacked by destination in each letter stacking room 2 and each large letter stacking room 3.
The letter groups 4a... thus accumulated in each letter accumulation chamber 2... and each large letter accumulation chamber 3... are all accumulated in the same accumulation form, that is, in a horizontal state.

In this way, letters with large quantities to the destination 4...
Since the letters are accumulated in the large letter accumulation chamber 3 with a large accumulation capacity through the same letter conveyance system 6 as the other letter accumulation chamber groups 2a, in the same horizontal state as the letter accumulation chamber group 2a, each letter accumulation The operation for taking out the letter groups 4a... accumulated in the chamber 2... and each large letter accumulation chamber 3... can be made extremely easy, and the number of times of take-out required for taking out the large letter accumulation chamber 3... can be reduced. be able to. Therefore, it is possible to save labor in the extraction work. Moreover, since the letters 4... accumulated by destination are conveyed and guided to each letter accumulation room 2... and each large letter accumulation room 3... by the same letter conveyance system 6, the structure is different from that of the conventional one. It can be simplified.

As explained above, according to this invention, one or more of the letter accumulation chambers in which letters are stacked horizontally is designated as a large letter accumulation chamber that has a larger letter accumulation capacity than the other letters, and this large letter accumulation is used to store letters. Since letters for large-volume destinations with a large amount of accumulated letters are stacked horizontally in the same way as letters stacked in other letter accumulation rooms, the letters collected in each letter accumulation room and each large-volume letter accumulation room The operation involved in taking out can be made extremely easy, and furthermore, the number of times required to take out the large-sized collection chamber can be reduced. Therefore, it is possible to save labor in the extraction work. Furthermore, since paper sheets are stacked horizontally even in the large stacking room, there is no need for a means to prevent paper sheets used for stacking in an upright position from falling over, making it easy to stack large amounts of paper sheets. It can be stored. Moreover, since the letters accumulated by destination are guided by the same letter conveyance system to each letter accumulation room and to the large letter accumulation room provided at the end of the line, the letters are transported to the large letter accumulation room. The structure of the conveyance path can be extremely simplified without providing an independent path.
