Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention detects the position of a stamp affixed to a paper sheet, such as a postal item, and
The present invention relates to a fixed position stop control device for stopping postal items with stamps attached at a fixed position in a stamping part in an automatic mail processing device that automatically stamps stamps and accumulates stamps by type and direction.

(Prior Art) Conventionally, in an automatic mail processing device, a fixed position stop control device as shown in FIGS. 1 and 3 is used to stop a mail with a stamp attached at a fixed position in a stamping section. It is being That is, the mail P taken out from the takeout section 1 passes through the detector 3 disposed on the conveyance path 2, and then passes through the photoelectric element 5a for driving the stamping section 9 disposed at a later stage.
5b, the data of the postal item P to which the stamp has been affixed is stored in the shift register 4, so the drive circuit of the stamp section 9 operates only for the postal item P for which this data has been detected. A clutch/brake system is used to drive the stamping section 9, and when a voltage is applied to the clutch side magnet 9a, the stamping section 9 starts rotating to stamp the stamp, and the clutch shaft ( When a notch in a disc (not shown) attached to a disc (not shown) is detected, the brake side magnet 9b operates to stop the stamping part 9.

However, with such a stamping method, if the mail P becomes clogged in the middle of the transport path 2,
If the machine is stopped immediately, the rotation of the stamping part 9 may be in the middle, and if the machine is stopped when it is about to start rotating, the rotation of the motor 12 will decrease and the rotation of the stamping part 9 will also decrease. Therefore, it does not stop at a predetermined position, and in extreme cases, it ends up stopping at a position that prevents the mail P from being carried in. This has the disadvantage that the stamp section 9 gets jammed when restarted.

(Problem to be solved by the invention) Conventionally, when a mail jam occurs in the middle of the conveyance path, if the machine is immediately stopped, the rotation of the stamping section also stops, but at this time, it does not stop at a predetermined position. In extreme cases, the machine may stop at a position that prevents mail from being carried in, resulting in a jam or the like in the stamp section when restarted. The present invention has been made in order to solve the above-mentioned problems, and is a fixed position stop control of the stamping section, which stops the rotation of the stamping section at a predetermined position based on the jam signal when a mail jam occurs. The purpose is to provide equipment.

[Structure of the invention]

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention includes: a conveyance path for conveying paper sheets; a stamp section provided on the conveyance path for imprinting a stamp on the paper sheets; a driving device that drives the stamping section; a first detection means that detects a position for stopping the stamping section at a predetermined position;
A stopping means is provided between the stamping section and the drive device to stop the stamping section at a predetermined position in response to the first detection means; 2 detection means, and this second detection means.
control means for stopping the drive device after a paper jam occurs in response to an output signal from the second detection means, and for stopping the stamping unit at a fixed position by the stop means in response to the output from the second detection means; It is composed of

(Function) That is, by having the above-mentioned structure of the present invention, it is possible to make sure that the stamping part is stopped at a predetermined position at the same time as the jamming signal is generated. Therefore, it is possible to prevent the problem of paper sheets becoming jammed in the stamping section at the time of restart.

(Example) The present invention will be described below based on an example shown in FIGS. 1, 2, and 4. However, in FIG. 4, the same reference numerals as in FIG. 3 indicate the same parts. In FIG. 1, a paper sheet, for example, a postal item P, taken out from a takeout section 1 passes through a detector 3 disposed on a conveyance path 2, whereby the presence or absence of a stamp is detected, and the stamp is affixed. The data of the mail P that is being stored is stored in the shift register 4. Thus, the above data is transferred at the timing when the mail P sequentially passes through the photoelectric elements 5a to 5f as it is transported.

Now, the postal item P is stamped with the photoelectric element 5 for stamping timing.
When the data of the shift register 4 and the output of the photoelectric element 5b are inputted to the AND gate 6 and an AND is taken, a delay circuit 7 for adjusting the stamping position on the mail P is triggered. Then, after a predetermined time, the delay circuit 7 outputs an output and sets the flip-flop 8. When this set signal drives the clutch-side magnet 9a of the stamping section 9, the stamping section 9 starts rotating, and the stamp is stamped on the mail P while being held between the character hub 9c of the stamping section 9 and the back-up roller 10. It is done.

In this way, when the stamping on the postal item P is completed, the notch 9 of the disk 9d attached to the stamping part 9
d' is detected by the photoelectric element 11 and the flip-flop 8 is reset. This reset signal drives the brake-side magnet 9b of the stamping section 9, and the stamping section 9 stops.

However, now in the middle of the conveyance path 2,
When the photoelectric element 5c detects the occurrence of a jam in the mail P, this detection signal is immediately transmitted as a "0" signal to the AND gate 13 to inhibit the output of the delay circuit 7 connected to the stamp drive circuit. Then, a so-called jam signal is generated, which inhibits subsequent stamp unit drive signals. Furthermore, this clog signal is transmitted to the delay circuit 1
4, the drive circuit (not shown) of the transport system and the motor 12 that drives the stamp section 9 are stopped.
Here, the delay time of the delay circuit 14 is set to the time required for one rotation of the stamp section 9, and if the stamp section 9 is about to start driving when a jam occurs, that is, when the flip-flop 8 is set. Even if it is instantaneous, the notch 9d' provided in the disk 9d of the stamping section 9 is detected by the action of the delay circuit 14, and the stamping section 9 is completely stopped, and then the motor 12 is stopped. I can do it.

As explained above, according to the present invention, the input to the stamp drive circuit is prohibited at the same time as the jam signal is generated, and the motor stop signal is sent after the delay circuit has secured time for one revolution of the stamp. Therefore, the stamp part can always be stopped at a predetermined position. Therefore, this has an excellent effect of preventing the problem of paper sheets jamming in the stamping section at the time of restart.
