Description

[Detailed Description of the Invention] [Industrial field of application] The present invention arranges and stamps postal items that are conveyed either upwards or downwards so that all the stamps are on one side, for example, on the bottom. The present invention relates to an automatic stamping and assembling machine for postal matter that has undergone processing such as the following.

[Conventional technology]

Conventionally, in this type of automatic stamping and stamping machine for postal items, it is necessary to position all the stamps of the postal items down, for example, in order to stamp the stamps correctly. Had to let. In the reversing unit for reversing upside down, as shown in FIG.
A single belt 17 is twisted in a state of being twisted by a roller, and a mail item 18 conveyed is
It was sent out with 0 ° inversion. Although the inverted postal matter 20 is sent to the alignment section, it is often lifted from the substrate 19 of the transportation route, and therefore, there is a belt 21 inclined with respect to the substrate 19 as shown in FIG. At the aligning section, the lower end of the mail piece is aligned properly along the substrate 19.

The width of the mail processed by the automatic mail sorting and stamping machine is generally 90 mm to 120 mm which is the UPU size, but it may be necessary to process up to about 90 mm to about 160 mm in other countries. In order to turn the mail upside down, the center of the turning is the minimum from the substrate of the transportation route, and half the maximum width is required. For example, a minimum of 80 mm is required to flip a mail item having a maximum width of 160 mm. If the value is smaller than this value, the postal matter of the maximum width hits the substrate of the conveyance route when it is reversed, and bending or the like occurs. As a result, problems such as jams and imprint defects occur.

Conversely, if the reversing center is set too high, when the narrow postal item is turned over, the center of gravity of the postal item is far from the reversing center, so the postal items may fly out of the reversing section due to centrifugal force during reversing. was there. Therefore, the center of reversal for reversing a postal matter having a width of 90 mm to 160 mm is 80 mm from the substrate surface of the transportation route, and is generally about 85 mm to 90 mm with a slight margin.

[Problems to be solved by the invention]

However, in the reversing section of the conventional automatic mail sorting and stamping machine described above, the center of reversal must be raised in order to reverse a large wide mail, but if it is raised, a narrow mail will become There was a drawback that problems such as jumping out of the machine occurred.

On the other hand, in recent years, the amount of large-sized thin mail items has been increasing, and there is an increasing demand for collecting and imprinting these mail items, but it is possible to process such large-sized mail items as well. This was not possible with conventional technology.

[Means for solving problems]

The automatic mail sorting and stamping machine of the present invention is composed of a stamp detector for detecting stamps on mail and a mail for which stamps have been detected and mail for which stamps have not been detected, based on the result of the stamp detector. The first switcher for switching the conveyance path, the width detector for detecting the width of a postal item for which no stamp is detected, and the conveyance of a postal item having a predetermined width based on the detection result of the width detector A second switch for switching the path, an up-and-down moving unit for vertically moving the position of the postal matter having a width of a predetermined size with respect to the transport surface, and a predetermined size in which the transport path is divided by the second switch. The mail having the width of the mail and the mail having the width smaller than the predetermined size are merged, and the conveying path is divided by the reversing unit for inverting the mail and the first switch. Postage stamp detected and postage stamp not detected And after merging the mailpiece, and a Seii unit coordinating integer by aligning their mailpieces to the substrate surface of the transport path.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a view showing an embodiment of the present invention. The stamp detectors 1 and 2 are provided on both sides of the transportation route to detect a stamp attached on the mail item 3. The transportation routes 4, 5 and 6 convey the mail item as it is. The width detector 7 is for detecting the width of the postal matter. In addition, the tumblers 8 and 9 are for switching the route through which the mail is conveyed based on the detection results of the stamp detectors 1 and 2 and the width detector 7, respectively. This is for reversing the top and bottom of the postal matter 80 mm from the board surface, and the aligning section 11 aligns the bottom end of the postal matter that has been lifted and conveyed correctly so that it can be conveyed along the board surface of the conveyance route. It is for ranking. further,
The up-and-down moving unit 12 lowers the postal matter passing therethrough by 40
mm for moving.

The postal matter 3 conveyed through the conveying route 4 is first detected by the stamp detectors 1 and 2, and the postal item having the stamp affixing position is switched by the tumbling device 8 for the postal matter. It is sent to the transport route 5. On the other hand, for postal items with the stamp pasting position above, the width is further detected by the width detector 7, and postal items with a width of 160 mm or less are sent to the transportation route 6 and those with a width of more than 160 mm and 200 mm or less. The transfer route of the object is switched by the tumbler 9 and is sent to the up-and-down moving unit 12. As shown in FIG. 2, the vertical moving unit 12 is
The sub-board surface 13 of the exit side transportation route is 40 mm below the entrance-side main board surface 14, and the postal matter 15 conveyed along the main board surface 14 is provided inclined with respect to the board surface. Up to 4 downwards while being transported by the belt 16
The postal matter is moved by 0 mm, and is sent out so that the lower end of the postal matter follows the sub-board surface 13 on the exit side. 160 mm
Even for mail with a width of ~ 200 mm, up to 40 can be moved up and down 12
Since it can be lowered downward by mm, the upper end of the mail is 8
It does not become larger than 0 mm, and the bottom edge of the mail does not go below the main substrate surface even after reversing.

The postal matter that has passed through the reversing unit 10 merges with the postal matter that has passed through the transport route 5 and is sent to the aligning unit 11 so that the lower end of the postal matter is properly aligned along the main substrate of the transport route. To be done. As a result, since all the stamp sticking positions are aligned downward and the stamps are conveyed along the main substrate of the conveying route, the subsequent stamping and accumulating processes are correctly and accurately performed.

[Effect of device]

As described above, according to the present invention, by providing an up-and-down moving portion that moves (upward) and downward (downward) with respect to the conveying direction of a mail item, a narrow width of a mail item that cannot be conventionally processed. It is possible to provide an automatic mail sorting and stamping machine capable of processing mail having a wide range of widths, including wide mail.
