Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a paper sheet group bundling device for bundling a group of paper sheets, such as a group of mails, through a data f.

[Technical background of the invention and its problems]

In recent years, in order to cope with the increase in the amount of mail, we have started to carry out each process of stamping standard mail from the sorting, sorting, stamping machine as a pre-processing device, sorting and collecting → taking out → attaching paper tags → bundling. Automatic mail processing equipment is being developed.

This automatic mail processing device has a configuration as shown in FIGS. 1 and 2. That is, in the figure, reference numeral 1 denotes a reading and sorting machine with an automatic dispensing function, and the output conveyance path 2 of this reading and sorting machine 1 is opposed to the conveyance path 4 of the bundling device 3, and these conveyance paths 2.4 are connected via a transfer device 5.

Further, a paper bill issuing device 6 is arranged opposite to a midway portion of the conveyance path 4 of the bundling device 3. The bundling device 3 has a horizontal bundling section 7 and a vertical bundling section 8.

Then, postal items A are supplied to the supply section 9 of the reading and sorting machine 1 and taken out one by one.The postal codes of the postal items A are read by the reading sections 10 and 11, and then conveyed to the automatic dispensing and sorting section 12, where they are sorted into sections corresponding to the postal codes. They are sorted and accumulated in boxes 13. And sorting box 1
When a certain amount of mail A... is accumulated in box 3, sorting box 1
The push plate, which also serves as the front wall of No. 3, moves rearward and is discharged into a circulation/gulet (not shown) of the transfer section (Tsyaleft circulation system #) 14. Then, the pallet that has received the accumulated mail group A... is sent through the cross-feeding section 15 and lowering section 16 of the transfer section 14 to the unloading section 17 as the output conveyance path 2 of the reading and sorting machine 1. .

Next, the mail group A in the pallet that has been sent to the unloading section 17 is delivered via the transfer device 5 into the horizontal bin conveyor 18 that forms the transport path 4 of the bundle device 3, and on the other hand,
The empty/flat pellets are returned to the rising section 19 via a return cross-feeding section (not shown) and circulated.

Further, the mail group A... put out into the horizontal bin conveyor 18 of the bundler 3 is intermittently conveyed, and the paper bill issuing device #6
A paper bill (not shown) on which the address information (post office name, etc.) specified in is printed is attached to the t-mail group A... and then to the horizontal bundling mechanism section 7 and the vertical bundling mechanism section 8. By facing each other in sequence, a cross-shaped bundle is performed.

Further, in the horizontal bundling mechanism section 7, as shown in FIG. The bundle is intermittently conveyed by the movement of .20, and is pushed between bundles f21 extending perpendicularly to the conveyance path 4, as shown in FIG. 3(b). The bundle Q21 is pulled out by the movement of the mail group A... from upper and lower reels (not shown). The tension of the bundle tape 21 at this time is adjusted by tension devices (not shown) provided on the upper and lower sides, respectively.

Next, when the movement of bottle pair 20.20 is completed, Figure 3 (c)
After the thieves 22 and 22 sandwich and seal the upper and lower packaging materials as shown in FIG. 3, the binding tape 2 is cut off to complete the band binding, as shown in FIG.

However, in the bundling mechanism 7 having the above configuration, in order to prevent the bundled mail group A from falling during delivery, the bundling tape must have an appropriate tension. There is a need. For this reason, the binding tape 2゛1 for mail group A...
If the rigidity of mail group A is insufficient, mail group A may curl up as shown in Figure 4.
In extreme cases, there is a serious problem that mail group A... may be cut off.

Therefore, when sorting, we count the number of mail pieces, and in the case of mail group A that does not meet a certain specified number of pieces, we predict that the rigidity is insufficient and eliminate it, and do not bundle the mail pieces. Although it is possible to prevent scratches, for example, the rigidity of 10 postcards and 10 envelopes with a thickness of five cabinets is significantly different, and if this specified number of sheets is set with mail A, which has less rigidity, it will be possible to bundle them. This means that there are many things that are excluded.

[Purpose of the invention]

The present invention has been made based on the above circumstances, and its purpose is to reliably prevent the extreme curling and damage of paper sheets caused by bundles, and to eliminate even those that can be bundled. The present invention aims to provide a bundling device for a group of paper sheets.

[Summary of the invention]

In order to achieve such an object, the present invention applies the fact that the rigidity of a group of paper sheets such as mail is approximately proportional to its thickness,
Before bundling, the device detects the stacking height (thickness and stacking height), and if the specified number of sheets is reached, it will be bundled without being rejected if it has a certain thickness, and if it is not thick enough, it will be rejected. It was designed to be excluded by

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 5 and 6. Note that the same members as those described above are given the same reference numerals and detailed explanations will be omitted.

Mail group A as a group of paper sheets delivered from the output conveyance path 2 of the reading and sorting machine 1 through the transfer device 5 in the vertical direction (longitudinal direction) is transferred laterally (in the lateral direction) by the bin conveyor 18. ), and the paper bill B is attached by the paper bill issuing device 6.

Between this paper bill issuing device 6 and the horizontal bundling mechanism section 7,
As shown in the figure, an optical detector 23 for detecting the thickness (accumulation height) of the mail group A and a removal device fli 24 are sequentially arranged along the mail transport direction.

The optical detector 23 is placed between the transport path 4Yr and the light source 25.
Because of the arrangement of the optical axis 27 and the light receiving element 26, the mail group A has a rigidity that will not cause excessive curling or damage even if the height of the optical axis 27 from the mail guide is large.・
It is set at a position corresponding to the thickness of the mail group A..., and depending on whether or not the mail group A... being conveyed follows the optical axis 27 or not, it may be possible to bundle the mail group A... or damage to the mail group A... It is designed to determine which items are likely to be stained.

Further, the removing device 24 uses an air cylinder 28 to move the dispensing body 2 in a direction perpendicular to the concave conveying direction of the mail group A...
It is configured to be able to reciprocate by 9 f, and the mail group A judged to be insufficiently thick by the detector 23 is transferred to the transport path 4.
``It is busy dispensing to the removal accumulation section 30 from above.

Therefore, the bundle mechanism section 7 only transports paper sheets that have a predetermined thickness and sufficient rigidity to withstand the bundle, and if the paper sheet group A... is extremely curled due to lack of rigidity, it will be damaged. can be reliably prevented. Also, I often exclude books that can be bundled.

Note that the mail group A horizontally bundled by the horizontal bundler mechanism 7
. . . Vertical bundling is performed by the vertical bundling mechanism section 8 to form a cross-bundling state, which is conveyed to the two-way sorting section 32 via the vertical conveyor 31.

In the above-mentioned embodiment, the attachment of bundles of paper sheets according to the present invention is applied to bundles of mail items, but the present invention is not limited thereto, and may be applied to bundles of cards, etc., for example.

Moreover, although the thickness of the paper sheet group is detected optically, for example, mechanical detection may be used.

It goes without saying that the present invention can be modified in various ways without departing from the gist of the invention.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to reliably prevent damage caused by excessive curling of paper sheets due to bundling, and it has the advantageous effect of eliminating even those that can be bundled.
