DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a stamping device for stamping a postal matter such as a sealed letter with a date and the like.

(Prior Art) An automatic postal sorting and stamping machine is provided with an exclusion section for selecting and eliminating postal matter containing foreign matter such as a seal or a key, so that postal matter containing foreign matter is not stamped. I have to.

By the way, in the rejecting section, all postal items that are rejected or rejected, or postal items directly supplied from the supply section of the sorting and stamping machine, all pass through the stamping device.

In this case, if the amount stamped is a stamp or other object to be stamped, regardless of the contents, all stamping will be performed, and postal items will be strongly hit between the stamping hub and backup roller that constitute the stamping device. Become.

(Problems to be solved by the invention) However, if a stamp is applied regardless of the contents of the mail, if a key or a seal is inside, the contents are destroyed or the envelope is cut due to the impact of the stamp. Jumping out of the vehicle occurs. These are called dirty losses and have become a major problem in recent years in improving postal services.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a stamping device for postal matter capable of preventing damage to contents and occurrence of popping out.

[Constitution of the Invention] (Means for Solving the Problems) In order to solve the above-described problems, the present invention provides a supply means for supplying the sealed letter in a postal stamping process having a stamping means for stamping a sealed letter. Transporting means for nipping and conveying the sealed letter supplied by the supply means with a belt, comprising a bent portion for changing the conveying direction of the sealed letter, and disposed near the bent portion of the transport means. And a foreign substance detecting means for detecting the foreign substance when the foreign substance is included in the sealed letter, and controlling such that when the foreign substance is detected in the sealed letter by the foreign substance detecting means, the sealing process is not performed on the sealed letter. And control means for performing the control.

(Operation) With the above-mentioned means, it is possible to stop all stamping on a sealed letter containing foreign matter.

Hereinafter, the present invention will be described with reference to an embodiment shown in the drawings.

FIG. 4 shows a mail processing apparatus. In the figure, reference numeral 1 denotes a supply table on which mails as sealed letters are placed. Reference numeral 2 denotes a supply unit that supplies mails on the supply table 1 one by one. The mail supplied from the supply unit 2 is sent to a thickness sorting unit 3 via a transport path, and the thickness sorting unit 3 has a thickness of 6 mm.
Thicker ones are removed. The postal matter that has passed through the thickness sorting section 3 is sent to a first width sorting section 4, where a piece wider than 235 mm is removed. Then, the mail having passed through the first width sorting unit 4 is shifted by the shifting unit 5 and then sent to the second width sorting unit 6, where the mail wider than 120 mm is removed.

The mail removed from the first and second width sorting units 4 and 6 is sent to the third width sorting unit 7 and the mail having a width smaller than 120 mm is removed.

The mails sorted by the second width sorting unit 6 are taken out one by one by the one-time taking-out unit 8 and sent to the hardness sorting unit 10 via the foreign matter detector 9.

After the hardness is determined by the hardness selection unit 10 in this manner, the hardness is sent to the buffer unit 11 and accumulated. The postal matter accumulated in the buffer unit 11 is taken out one by one, sent from the first stamp detection unit 12 to the positioning unit 13, and sent from the positioning unit 13 to the second positioning unit 13.
A stamping device via a hard object detecting device 16a and a metal detecting device 16b as foreign matter detecting means described later via a stamp detecting unit 15
It is sent to 17 and stamped.

The pressed mail is collected by the rejection stacking unit 20, special stacking unit.
19, the sheet is sent to the normal stacking section 18 and the sorting section connecting section 22 to be stacked.

Meanwhile, the stamping device 17 is configured as shown in FIG. That is, in the figure, reference numeral 31 denotes a stamp hub, and the backup roller 32 is opposed to the stamp hub 31.
Further, an ink roller 33 is provided adjacent to the stamp hub 31 so as to supply ink to the stamp hub 31.

When foreign matter is detected in the postal matter t, the backup roller 32 is retracted by the retraction drive device 51 shown in FIG. 6 to widen the gap between the backup roller 32 and the stamp hub 31. Thus, the postal matter t conveyed by the conveyor belt 34 is stamped with date and the like by passing between the stamp hub 31 and the backup roller 32.

The hard object detecting device 16a is configured as shown in FIG.

That is, in the drawing, reference numeral 25 denotes a detection lever provided on the upstream side of the stamping device 17, and this detection lever 25 is provided rotatably, and its rotation end is formed in a curved shape and serves as a bent portion. It is close to the transfer surface 26. On the transport surface 26, the transport direction of the mail is variable. The detection lever 25 is connected to the stamping device 17 via a detection circuit 27.
Is connected to the mechanism control unit 28.

The metal detector 16b is configured as shown in FIG.

The metal detection device 16b uses a commercially available magnet. When a metal is present, the magnetic force changes, and this is connected to a change in resistance to detect the change. The metal detector 16b is connected to the controller 28 of the stamping device 17.

As shown in FIG. 1, the postal matter t sent along the transport surface 26 is a foreign matter, for example, a hard material 29 such as a seal.
Is included, the seal is transported along the transport surface 26 without bending, and the thickness of the postal matter t is increased. The detection lever 25 of the hard object detection device 16a rotates as shown by the broken line, and is detected by the detection circuit 27. As described above, when the foreign matter 29 is detected, the operation of the pressing device 17 is stopped by the mechanism control unit 28, and the postal matter t is conveyed without being stamped.

Also, as shown in FIG.
When the metal is conveyed by the pinching device 40 and the metal is detected facing the metal detecting device 16b, the stamping device 17 is controlled via the control unit 28.
Is stopped and conveyed as it is without being stamped.

As described above, the hard and metal detectors 16a, 16b
Therefore, the foreign matter in the postal matter t is detected, and when it is detected, the stamping device 17 is stopped, so that the postal matter t is not damaged and the contents thereof can be damaged or popped out. It will surely be prevented.

In addition, since foreign matter in the stamping device is detected, if there is a foreign matter in a place other than the stamped portion, stamping can be performed without any trouble, and good processing efficiency can be maintained. Further, since the transport direction of the postal matter t is changed by bending the transporting surface 26 close to the detection lever 25, if foreign matter is included in the postal matter t, the foreign matter is folded along the transporting surface 26. The postal matter t is pushed up from the inside without being bent, and the thickness of the postal matter t on the transport surface 26 increases. Therefore, even if the postal matter is conveyed to the detection lever 25 with a thickness within the predetermined thickness, the foreign matter can be detected, and particularly when the foreign matter is long, the foreign matter can be more reliably detected. Can be detected.

[Effects of the Invention] As described above, when a foreign matter in a sealed letter is detected by the foreign matter detecting means, the sealing means is stopped. Serviceability can be improved.

In addition, a bent portion for changing the transport direction of the sealed letter is provided in the sealed letter conveying means, and in this bent portion, the foreign matter in the sealed letter is detected by the foreign matter detecting means, so that when a foreign matter is included in the sealed letter, The foreign material does not bend along the bent portion, but pushes up the sealed letter from the inside, and the thickness of the sealed letter increases. Therefore,
Even if the sealed letter is conveyed to the foreign matter detecting means in a thickness within a predetermined thickness, the foreign matter can be detected, and particularly when the foreign matter is long, the foreign matter can be more reliably detected. .
