Next, the operation of the automatic mail sorting / sorting and stamping device 1 will be described with reference to FIGS. 1, 2 and 3. FIG. 1 is a flowchart of a forward / reverse branching device 39 that determines a forward / reverse operation by the first detection unit 23 and the inversion unit 25.

First, a large amount of mail is put into the supply table 7 by an operator (not shown). The input postal matter is conveyed to the thickness selection unit 11 by the supply unit 9 having a supply conveyor (not shown). The thickness sorting unit 11 sorts the thickness of the postal matter conveyed from the supply unit 9, eliminates thick postal matter thicker than a predetermined thickness, and then removes the postal matter within the predetermined thickness not eliminated here. The product is sent to the first width selection unit 13. Further, the accuracy of width selection is increased by the second width selection unit 15, the third width selection unit 17, and the fourth width selection unit 19. The postal items determined to be wider than the predetermined width by the width selection units 13, 15, 17, and 19 are excluded.

The fixed-size mail items that have passed through 17 and 19 are stored in the buffer unit 21.
Is supplied to. The buffer unit 21 keeps the trailing edges of the fixed-size mail pieces and other fixed-size mail pieces at a constant value, and sends them to the first detection section 23 one by one. In the first detection unit 23, the light-emitting element of the detector irradiates the lower surface of the postal object with light, and the reflected light from the postal item 50 is received by the light-receiving element of the detector. After this detection operation, the first detection unit 23
It is determined whether or not the above-mentioned detection target is detected (step 1).

Here, if the object to be detected is detected, the forward / reverse branching device 39 does not depend on the detection result of the height detection sensor 35 provided in the reversing unit 25, but at the timing taken by the forward / reverse branching control sensor 37. In addition, the postal matter 50 is sent out to the forward rotation belt 41 side (step 2).

After step 2, the forward / reverse branching device 39 for controlling the forward / reverse operation of the mail sent subsequently.
Performs step 1. After that, the postal matter 50 is again detected by the second detector 27, and when the second detector 27 detects an object to be detected, it is stamped by the stamping section 29. The postal matter 50 that could not be detected by the first detector 23 in step 1 is the height detection sensor 3 of the reversing unit 25.
The height is detected by 5 (step 3).

As a result of the height detection operation, when the postal matter 50 is higher than a predetermined height, that is, when the optical path formed by the height detection sensor 35 is blocked by the postal matter 50, the postal matter 50 is reversely conveyed. Therefore, there is a high possibility that the mail will be damaged. Therefore, the postal matter 50 is forcibly sent to the forward rotation belt 41 side by the forward / reverse branching device 39 at the timing taken by the forward / reverse branching control sensor 37. The postal matter 50 forcibly sent to the forward rotation belt 41 side is sent to the second detection unit 27. Then, after the detection operation by the second detection unit 27, it is supplied to the imprinting unit 29.
Since the object to be detected has not been detected, the stamping unit 29 does not stamp the stamp.

When the postal matter 50 is lower than a predetermined height as a result of the detection operation of the height detection sensor 35 in step 3 after step 1 and step 3, that is, the optical path formed by the height detection sensor 35. If the postal matter is not blocked by the postal matter 50, the forward / reverse branching device 39 sends the postal matter 50 to the reverse belt 43 side at the timing taken by the forward / reverse bifurcation control sensor 37 (step 4).

After step 4, the forward / reverse branching device 39 for controlling the forward / reverse operation of the mail sent subsequently.
Performs step 1. The reversing belt 43 is sandwiched between the facing rollers 45 and 47 and reverses and conveys the postal matter 50. Mail 5 sent to the reversing belt 43 side
After that, 0 is supplied to the second detection unit 27. Here, the light emitting element of the detector irradiates the lower surface of the postal matter 50 with light in a state of being reversed and conveyed, and the reflected light from the postal matter 50 is received by the light receiving element of the detector. With this detection operation, the second detection unit 27 determines whether or not the detection target of the postal matter 50 has been detected. If the detection object can be detected by the detection operation of the second detection unit 27, the stamping unit 29 stamps the detection target. If the object to be detected is not detected, this stamping will not be done.

After passing through the stamp portion 29, the postal matter 50 is supplied to the stacker portion 31. Here, the postal matter 50 is classified and accumulated into an ordinary mail that has been imprinted, a special delivery that has been imprinted, a mail that has not been imprinted, and the like. The automatic postal sorting and assembling and stamping device 1 is operated and controlled by the central operation panel 33.

The present invention is not limited to the above embodiment, and when the optical path formed by the height detection sensor 35 is blocked by the postal matter 50, the postal matter 50 can be conveyed to the supply base 7. .. As described above, the present invention can be variously modified within the scope of the invention.
