Description

[Detailed description of the invention] The present invention relates to a recognition marker device for mail that stamps recognition marks such as 1, 2, 3, etc., or A, B, C, etc., or other symbols, etc. on the mail being conveyed. .

Conventionally, there are recognition marker devices of this type as shown in FIGS. 1 and 2. That is, a drive system 5 is provided so that both the type roller 1 for imprinting the recognition mark and the push roller 2 have the same circumferential speed at the outermost periphery, and the type roller 1 attached to the type roller 1 and the ink roller 3 are lightly pressed. By touching it, you can obtain ink and stamp it on postal items such as letters 4.

The drive system 5 is composed of a driving shaft 7 connected to a prime mover (not shown) and two idler pulleys 8 and 9, and a belt 10 is wound between them. Drive roller body 1 that pivotally supports type roller 1
1 is in contact with the belt 10, and the rotation of the driving shaft 7 is transmitted thereto. The idle pulley 9 is also provided with a coaxial small pulley 12.
Rotation of the driving shaft 7 is transmitted by a round belt 13 that is wrapped around the push roller 2. Therefore, the type roller 1 and the push roller 2 rotate at the same circumferential speed as described above. In the figure, reference numeral 14 denotes a spring, which causes the push roller 2 to generate a pressing force against the letter 4.

Two conveyor belts 17 and 18 that convey the mail
are idler rollers 15 and 1 at the ends of the conveying section, respectively.
6 are arranged to move in close contact. The letter 4 is carried by two conveyor belts 17 as shown in the figure.
18 and conveyed on a base plate 19 in the direction of arrow A.

The conveyor belts 17 and 18 are arranged at a position where the letter 4 sandwiched between them comes into contact with the push roller 2 and moves, and while the letter 4 is in contact with the push roller 2, the letter 6 is moved by the type roller 1. It will be stamped.

However, in the conventional mail recognition marker device described above, the drive system 5 is complicated and must be installed from the design stage for the purpose of marking, and in particular, the existing mail conveyance device etc. If it becomes necessary to add a recognition marker device to the equipment, the cost of the device is expensive, and the modification work is extensive and the construction cost is also high. It has been desired to obtain a mail recognition marker device that has a simple mechanism and can be completed at low cost.

The object of the present invention is to solve the above-mentioned problems of the conventional mail recognition marker device and provide a much-needed device. Specifically, the drive source is the rotational force of the idler roller on which the flat conveyor belt that conveys the mail is attached, and the recognition mark is affixed in print along the flat conveyor belt at a midway position along the conveyance section of the mail. A mail system in which a roller is installed upright, the idler roller and the type roller are continuously rotated by an endless round belt, and one or several recognition marks can be imprinted on the mail being conveyed. The present invention aims to provide an object recognition marker device.

The details of the present invention will be explained below based on the drawings.

FIGS. 3 and 4 are diagrams showing an embodiment of the present invention. In the following, a case will be described in which a mail recognition marker device according to the present invention is added to an existing mail transport device.

Focusing on the fact that the idler rollers installed in the existing mail conveyance device receive rotational force from the conveyor belt that conveys the mail, only one of the two idler rollers, idler roller 20, rotates. Replace it with one that has a V-groove 21 for force transmission, and use this as the drive source. The remaining existing idler rollers 22 are used as they are. Like the idler roller 20, a type roller 24 having a V groove 23 formed therein is rotatably installed at a midway position in the conveyance section of the mail. At the bottom of the type roller 24, type characters 25 for stamping are attached so as to be replaceable.

In the figure, reference numeral 26 denotes an endless round belt, which connects the idler roller 20 and the type roller 24.
The rotational force applied by the flat conveyor belt 27 to the type roller 24 is transmitted to the type roller 24. The V grooves 21 and 23 of the idler roller 20 and the type roller 24 have a cross-sectional shape so that the endless round belt 26 does not protrude outward, and the movement of the flat conveyor belt 27 is not hindered. be.

In the figure, 28 is a push roller, and the flat conveyor belt 27
It is provided at a position corresponding to the type 25 of the type roller 24 with another flat conveyor belt 29 in between. The mail such as a letter 30 being conveyed between the flat conveyor belts 27 and 29 is pressed toward the type roller 24 by the push roller 28,
A predetermined recognition mark is stamped by the printed characters 25 that have come into contact with the ink roller 31 and obtained ink. This push roller 28 is made of a resin material in order to increase the rebound speed and reduce its weight, and is designed to prevent ink from being hit by the convex type 25 in the middle even when it rotates, and to prevent the ink from scattering onto the push roller 28. A concave recess 32 is provided to prevent the mail from adhering to the mail. O-links 33 made of soft rubber are attached to the upper and lower ends of this recess 32 to serve as a shock absorber, and by bringing them into contact with the type roller 24, the type roller 24 and the push roller 28 can have the same circumferential speed. Make it. Further, the push roller 28 has a plate spring 24 attached thereto so that the pushing force against the type roller 24 can be changed as desired, and can be adjusted by rotating the support shaft 35.

The type 25 is attached to the type roller 24 by screws, so that it can be replaced or changed easily.

When stamping the letter 30, the circumferential speed of the surface of the type 25 is the same as the running speed of the flat conveyor belt 27,
Moreover, since it rotates at a constant period, if a mail such as a letter 30 is located between the type roller 24 and the push roller 28, depending on the length of the mail, for example, one piece of mail will be sent to the smallest standard size, and one piece will be sent to the largest standard size. ~2 recognition marks are stamped at arbitrary positions.

As explained above, according to the present invention, the drive source is the rotational force of the idler roller on which the flat conveyor belt that conveys the mail is attached, and the flat conveyor belt is attached to the flat conveyor belt at a position midway through the conveyance section of the mail. A type roller with a recognition mark is erected along the line.
The above idler roller and type roller are continuously rotated by an endless round belt.
By making it possible to stamp one or several identification marks on the mail being transported, the mechanism is much simpler than conventional equipment, and modification work is mainly done by assembling with nuts, making it possible to make fewer holes. It requires only additional work such as tap cutting, is inexpensive, and has great effects, and is also suitable for initial maintenance of mail conveyance equipment.
