Abstract

PURPOSE:To obviate generation of a shock on the contents of mail during the passage of the mail and contrive prevention of fouling by stopping a stamping means when a foreign matter contained in mail is detected. CONSTITUTION:A back-up roller 32 is opposed to a stamping hub 31 of a stamper 17, and an ink roller 33 is disposed adjacent to the hub 31 to supply an ink to the hub 31. When a foreign matter contained in mail is detected, the back-up roller 32 is retracted by a refraction driver 51 to broaden the gap between the back-up roller 32 and the stamping hub 31. A detecting lever 25 of a hard matter detector is disposed turnably, and a turnable end thereof having a curved shape is disposed close to a feeding surface 26. The detecting lever 25 is connected to a mechanism-controlling part 28 of the stamper 17 through a detecting circuit 27. This metal detector is a commercial one utilizing magnetism, and is connected to the controlling part 28 of the stamper 17.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a stamping device for stamping a date, etc. on a postal item such as an envelope, for example.

(Prior art) A mail automatic sorting, sorting, and stamping machine is equipped with a removal section that sorts and eliminates mail items containing foreign objects such as stamps and keys, and is designed to avoid stamping mail items containing foreign objects. I have to.

By the way, in the above-mentioned rejection section, mail items that were not rejected,
Alternatively, all mail items directly supplied from the supply section of the assortment stamping machine pass through the stamping device.

In this case, if the face of the postal stamp is a stamp or other stamp, the stamp will be stamped on all items regardless of the contents, and the mail will receive a strong blow between the stamping hub and the backup roller that make up the stamping device. Become.

(Problem to be Solved by the Invention) However, if a seal is affixed regardless of the contents of the mail, if there are keys, seals, etc. inside, the impact of the seal may destroy the contents or tear the envelope. This may cause the product to pop out. These are called dirty losses and have become a major problem in recent years in improving postal services.

The present invention has been made in view of the above-mentioned circumstances, and its object is to provide a stamping device for mail items that can prevent the contents from being damaged or flying out.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention includes a stamping means for stamping a mail being conveyed, and a stamping means provided upstream of the stamping means for stamping the mail. The present invention is characterized by comprising: a detection means for detecting a foreign object within the seal; and a control means for stopping the operation of the stamping means when the foreign object is detected by the detection means.

(Function) By the above means, it is possible to stop stamping all mail items containing foreign objects.

(Example) The present invention will be described below with reference to an example shown in the drawings.

FIG. 4 shows a mail processing apparatus, and 1 in the figure is a supply table for uMing mail. Reference numeral 2 denotes a supply unit that supplies the mail pieces on the supply table 1 one by one.

The mails supplied from the supply section 2 are sent to the thickness sorting section 3 via a conveyance path, and the thickness sorting section 3 removes those having a thickness of more than 6y. The mail that has passed through the thickness sorting section 3 is sent to a first width sorting section 4, where mail items wider than 235111JI are removed. The mail that has passed through the first width sorting section 4 is then shifted by the shifting section 5 and sent to the second width sorting section 6.
Those wider than 12011121 are removed.

Note that the mail items removed from the first and second width sorting sections 4 and 6 are sent to the third width sorting section 7, and those narrower than 120 mm are removed.

Further, the mail items sorted by the "-2 second width sorting section 6 are taken out one by one by a mail takeout section 8, and sent to the hardness sorting section 10 via a foreign object detector 9.

After the hardness is determined in the hardness sorting section 10 in this way, it is sent to the buffer section 11 and accumulated.

The mail accumulated in this buffer section 11 is taken out one by one and sent from the first stamp detection section 12 to the alignment section 13, and from this alignment section 13 via the second stamp detection section 15, foreign object detection, which will be described later, is carried out. The stamped mail is sent to the stamping device 17 via the hard object detection device 16a and metal detection device 16b as means and is stamped. This stamped mail is sent to the removal stacking section 20, the special stacking section 19, the normal stacking section 18, They are each sent to the sorting machine connecting section 22 and accumulated therein.

By the way, the stamping device 19 is constructed as shown in FIG. That is, numeral 31 in the figure is a stamping hub, and a backup roller 32 is opposed to this stamping hub 31. Further, an ink roller 33 is provided at a distance from the stamping hub 31 to supply ink to the stamping hub 31.

When a foreign object is detected in the mail panhandler, the backup roller 32 is moved backward by a backward drive device 51 shown in FIG. 6 to widen the gap between the backup roller 32 and the stamping hub 31. The mail t conveyed by the conveyor belt 34 passes between the stamping hub 31 and the backup roller 32 and is stamped with a date and the like.

Further, the hard object detection device 16a is constructed as shown in FIG.

That is, in the figure, reference numeral 25 denotes a detection lever provided upstream of the suppressing device 17. This detection lever 25 is rotatably provided, and its rotary end is formed in a curved shape and is located close to the conveyance section 26. has been done.

This detection lever 25 is connected to the stamping device 1 via a detection circuit 27.
It is connected to the mechanism control section 28 of No. 7.

Further, the metal detection device 16b is constructed as shown in FIG.

This metal detection device 16b is an application of commercially available magnetism, and when metal is present, the magnetic force changes, and this is connected to a change in resistance for detection. This metal detection device 16b is connected to the control section 28 of the stamp device 17.

As shown in FIG.
9, 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. In this manner, when the foreign object 29 is detected, the mechanism control unit 28 stops the operation of the suppression device 17, and the mail item [ is transported as it is without being stamped.

Moreover, as shown in FIG.
．． 40, and when metal is detected facing the metal detection device 16b, the stamping device 17 is stopped via the control unit 28, and the stamping device 17 is conveyed as is without being stamped.

As described above, the hard object and metal detectors 16a, 1
6b detects a foreign object inside the mail item, and if detected, the stamping device 17 is stopped, so that the mail item t is not damaged and its contents are not damaged or thrown out. will definitely be prevented.

In addition, since a foreign object is detected at the stamping position, if there is a foreign object in a place other than the stamping part, the stamp can be stamped without any problem, and processing efficiency can be maintained well.

[Effects of the Invention] - As explained above, according to the present invention, when a foreign object is detected in a mail item, the stamping means is stopped, so that there is no impact on the mail item when it passes through. It is possible to improve the serviceability of postal services by preventing dirt and damage.

Further, since foreign matter is detected at the stamping position, if there is a foreign matter at a location other than the stamping part, the stamp can be stamped without any problem, and processing efficiency can be maintained favorably.
