Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying mechanism having a function of arranging and sorting out defective items in the process of conveying a plurality of paper sheets that are sorted and accumulated.

This Tanuki device is used, for example, in automated equipment for sorting and bundling mail. The first system of this type is
As shown in the figure, the postal code written on the postal item 4 is optically read, and based on the result, the postal mte is placed in a predetermined storage box 5.
The mail is automatically sorted and collected, and the mail is collected! P/
An automatic pick-up and sorting machine 1 for automatically collecting and discharging postal items 4 onto a conveyor 3, an automatic bundling machine 2 for automatically bundling the sorted and accumulated mail 4, and an automatic pick-up sorting machine. There is a system consisting of f1 and a conveyor 3 for sequentially conveying the accumulated mail from 1 to an automatic binding machine 2.

However, in the above system, in order to load the mail items sorted and accumulated in the automatic picking and sorting machine 1 onto the transport conveyor 3 and supplying them to the automatic bundling machine 2, the collecting box 5 of the automatic picking and sorting machine 1 is used. Postal items that have been stacked incorrectly, such as crumbling, when being removed from the stacking box 5, or when being removed from the automatic bundling machine 2.
Since mail items that have collapsed during transportation are fed to the automatic binding machine 2, there may be problems with bundling such as breakage of jammed bundles due to collapsed mail items, etc. This caused problems such as damage to the bundled mail items, significantly impairing the stability and efficiency of the bundling work. In addition, since the amount of accumulated mail conveyed from the automatic pick-up and sorting machine 1 is not necessarily constant, mail with a small amount of accumulated mail may be incorrectly inserted into the automatic bundling machine 2 or bent within the bundling, etc. As a result, the binding work had to be interrupted.

The present invention corrects the collapse of four-piece paper sheets in the process of conveying the stacked paper sheets taken out from the automatic take-out and sorting machine to the automatic binding machine, and also corrects the collapse of paper sheets that could not be completely corrected. By sorting and eliminating leaves, and further detecting the stacking state and stacking amount of stacked paper sheets, automatic bundling machine - ＼Bunds the stacked paper sheets supplied, and prevents jams at the time of 8 bundles. In addition to solving problems such as poor bundling, the present invention realizes a device that transports rejected paper sheets to a reprocessing process.

Next, an example of the present invention will be shown! Figures 2 to 4 are 111
A detailed explanation of the present invention will be given below.

In the figure, the structure and functions of the automatic pick-up and sorting machine 1 are the same as those described in the conventional example, and will therefore be omitted. Conveyor 3 is 111
A plurality of partition plates 6 opened in one plane direction are intermittently circulated horizontally along a vertical plane via a chain etc. by a drive motor (not shown) so as to be reversed at the terminal end 10. Driven. Note that while mail is being loaded in the side direction of the transport conveyor 3, the width is smaller than the width of the mail blade 4 to be loaded.

In addition, on both sides of the stop position of the f-feeding conveyor 3, a force-feeding conveyor (which can swing while remaining parallel to the plane 911) is installed at a variable predetermined speed via a cam mechanism 11 driven by a motor or the like. A guide plate 7 is provided, and on the exit side of the guide plate 7 portion, a photoelectric switch 12 for detecting protrusion is provided vertically on the side of the conveyor 3.
A photoelectric switch 13 for detecting an accumulation bin is installed at a predetermined position above the loading surface of the conveyor 3 so as to intersect with the conveyor 3.

Further, at the stop position of the automatic binding machine transfer portion of the transport conveyor 3, an air cylinder or the like is intermittently driven to push the accumulated mail 4 on the transport conveyor 3 to the binding machine 2IIll based on the detection result. A transfer mechanism 14 is installed.

Further, below the transport conveyor 3, there is a rejection conveyor 8 and a discharge conveyor 3 for loading mail items 4 that have not been supplied to the automatic bundling machine 2 and sending them back to the automatic pick-up and sorting machine 1 side for reprocessing.
A shaker 9 is installed to guide the mail 4 rejected from the mail onto the rejection conveyor 8.

Incidentally, on the side of the transport conveyor 3, there is a stack of mail 4 to be transported.
A guide (not shown) is installed to prevent the structure from collapsing.

Next, the operation will be explained with reference to FIGS. 2 to 4.

When the accumulated mail 4 loaded on the conveyor 2 and conveyed from the automatic pick-up and sorting machine 1 stops at the swingable guide plate 7, the cam mechanism 11 of the guide plate 7 is driven. The motor rotates and the guide plate 7
is initially 0. It swings at a predetermined speed of I Iv's or higher to create a predetermined gap with the side surface of the conveyor 3, corrects the part of the stacked mail 4 that is about to crumble, and spreads debris on the 1fi11 side of the conveyor 3. Postal items 4 which cannot be corrected and have stood horizontally are provided on both sides of a conveyor 3.

- Sorting and rejecting onto the rejecting conveyor 8 via the filter 9. After that, the guide plate 7 returns to the transport conveyor 3 side at a low speed of Q, 1 m/s or less, and when the accumulated mail 4 is arranged in the width of the transport conveyor 3, the transport conveyor 3 opens the movement FM, and the guide plate 7 A photoelectric switch 12 for detecting protrusion installed at the exit of the conveyor 3 checks whether the dyed mail pieces 4 are arranged within the width of the transport conveyor 3, and a photoelectric switch 13 for exporting the accumulated amount After checking whether the amount of accumulated mail 4 is within the range that can be bound, the accumulated mail 4 is conveyed to a fully automatic binding machine 2111.

When the transport conveyor 3 stops at the automatic bundling machine 2 section, the transfer mechanism 14 to the automatic bundling machine 1 only moves the accumulated mail 4 to the automatic bundling machine 1 side if it is determined that there is no problem with bundling based on the above-mentioned check results. The accumulated mail 4 on the conveyor is supplied to the fully automatic binding machine 2.

In addition, in the case of the accumulated mail 4 that is determined to be impossible to bundle, the transport conveyor 3 is moved without performing the above-mentioned transfer operation, and the partition plate 60 is reversed at the terminal end portion 11 of the transport conveyor 3 to separate the mail. 4 is dropped onto the rejection conveyor 8.

Furthermore, the rejected mail pieces 4 dropped onto the reject conveyor 8 are transported to a predetermined reprocessing step, that is, to the mail piece 4 resupply position of the automatic picking and sorting machine 1 in this embodiment.

As explained above, the present invention has a simple structure that prevents the stacked mail pieces from collapsing and becoming irregular in the process of transporting the stacked mail pieces taken out from the mail sorting unit # etc. to the automatic bundling machine. In addition to effectively correcting mail, by sorting and eliminating only mail that cannot be corrected and supplying only normal stacked items and items to the binding machine, troubles such as no-shaming and poor bundling in the binding machine can be eliminated, and further labor is required. By automatically conveying the rejected mail items that were previously sent to the reprocessing process by the rejected conveyor, the efficiency of the mail sorting and bundling system can be improved.
