DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet conveying roller, and more particularly to a sheet conveying roller having a dust collecting function.

[0002]

2. Description of the Related Art In the case where various kinds of processing are performed while paper and other papers are carried in and conveyed to a conveyance device, for example, in a case where printing is performed while conveying paper cut into a predetermined size, Paper dust and ink particles of a printing machine such as IJP (ink jet printer) generated on paper during transportation are scattered,
These scattered paper dust and ink not only adhere to the transport device and contaminate the device, but also adhere to parts such as sensors that detect the presence or absence of paper sheets, destabilizing their operation, Had been reduced.

[0003]

Heretofore, there has been an attempt to install a dust removing mechanism for removing or absorbing paper dust and ink particles as a countermeasure for these problems. For example, Tokiko 7-166
No. 60 describes an example in which, on a paper transport line, a dust removing roller provided with a brush on the outer periphery, a blowing unit for blowing air, ultrasonic waves, and the like, and a suction unit for sucking small dust separated from the paper surface are described. ing.

However, as seen in this prior example, a series of dust removing or dust absorbing mechanisms such as a dust removing roller, a spraying unit, and a suction unit are configured as a separate mechanism from the paper sheet transporting device. However, the overall size of the transport device is large because only the additional mechanism is added, which is a major factor that hinders the compactness of the transport device.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the transport roller 1 with a dust collection function according to the present invention has an intake hole 3 opened in the body of a roller body 2. The intake hole 3 is a hollow shaft 4 and a shaft that support the roller body 2. 4 is connected to an air suction mechanism 6 through an air hose 5 connected to the inside. The air suction mechanism is a dust removing device, specifically, an air compressor.

That is, the conveying roller 1 with the dust collecting function according to the present invention has a conveying function as a sheet conveying roller of the sheet conveying device, and a paper dust and other dust generated by conveying the sheet. And a dust collecting function for removing dust from the transport line.

In FIG. 1, a conveying roller 1 having a dust collecting function is shown.
The roller body 2 has a body having a middle height and a bearing 7.
Is rotatably mounted on the circumference of the shaft 4 via
The shaft 4 is supported in a cantilever manner on a machine frame 8 of the transfer device. However, how to support the shaft 4 on the machine frame is a matter of design, and is not necessarily limited to the case where the shaft 4 is supported on the machine frame in a cantilever manner.

The roller body 2 is hollow and has a suction hole 3.
2, are opened at positions not blocked by the belt 9, that is, at several places on the circumference of both ends of the body except for the center region of the body of the roller body 2 around which the belt 9 is stretched. Things.

The shaft 4 has a shaft hole 11, and the roller body 2 is rotatably supported by the bearing 7, and the inside of the roller body 2 is blocked by a seal 10 from entering dust. The hollow portion of the roller body 2 is communicated with the shaft hole 11 through a through hole 12 opened on the outer periphery of the shaft 4.

Therefore, the suction force generated by the air suction mechanism 6 directly acts on the intake hole 3 of the roller body 2 through the air hose 5 and the shaft 4. Note that, in order to increase the degree of freedom of the installation location of the air suction mechanism 6, the air hose 5
Preferably, a flexible material is used.

The belt 9 applied to the roller body 2
Is fed continuously in one direction, and conveys paper sheets in one direction. The roller body 2 rotates in one direction as a support mechanism of the belt 9. In the present invention, the suction force generated by the air suction mechanism 6 is transmitted to the shaft 4 via the air hose 5.

The suction force transmitted to the shaft 4 is transmitted from the shaft hole 11 of the shaft 4 to the inside of the roller body 2 through the through hole 12, and external dust and dirt are sucked into the roller body 2 through the suction hole 3. Is done.

The sucked dust and the like are separated from the roller body 2,
It is sent to the air suction mechanism 6 via the shaft 4 and the air hose 5. The dust and dust generated near and around the roller body 2 in this manner are removed from the paper sheet transport line through the roller body 2.

The transport roller 1 with a dust collecting function according to the present invention has a dust collecting function of dust and dirt, but has a transport function of giving a one-way transport feed to the belt 9 as an original function. As shown in FIG. 3, similarly to the other transport rollers 13, it is arranged as one of the transport rollers.

Next, referring to the example of FIG. 3, a detailed description will be given of an example in which the leaf conveying roller with the dust collecting function of the present invention is used in the vicinity of a printing device provided in the paper sheet conveying device 15, for example, IJP14. Will be described.

In FIG. 3, the IJP 14 is arranged in the middle of a paper sheet transport line, and sprays ink when paper sheets to be printed, for example, mail, passing the front surface thereof, pass through the paper. When printing information such as an address on a postal matter, a small amount of scattered ink particles float in the air. The ink particles flying in the air are also included in the dust and the like in the present invention.

The transport roller 1 with the dust collecting function installed downstream of the IJP 14 sucks ink particles floating in the air, and prevents the ink particles from adhering to and contaminating each part of the paper transport device 15. Of course, the transport roller 1 with the dust collecting function is rotated by the movement of the belt similarly to the other transport rollers 13, and transports the paper sheets in a predetermined direction along the transport line.

FIG. 4 shows an example in which a transport roller 1 with a dust collecting function is provided at a joint between two transport belts 9a and 9b for delivering paper sheets on a transport line. Paper dust is generated especially from paper sheets at the connecting portion of the belts 9a and 9b such as between the transport roller supporting the feed end of the one transport belt 9a and the transport roller supporting the feed start end of the other transport belt 9b. Cheap.

In this embodiment, the conveying roller 1 with the dust collecting function is applied to either the conveying end of one belt, which is the connecting portion of the conveying belt, or the starting end of the feeding of the other belt. . In this embodiment, the normal transport roller 13 is used as a roller at the feed end of the previous transport belt 9a, whereas the transport roller 1 with a dust collection function is used as a roller at the feed start end of the next transport belt 9b. ing.

As a result, the conveying roller 1 having the dust collecting function
Can suck and remove the paper dust generated in the transfer line, particularly in the connecting portion of the belt, and can prevent the generation of the contamination of each part of the apparatus due to the paper dust.

[0027]

As described above, according to the present invention, dust and dirt can be removed from the transport line by the dust-absorbing function of the roller with the dust collecting function to prevent the paper sheet transport device from being stained. Since the dust collecting function is applied to the belt conveying roller, there is no need to separately provide a dust suction mechanism on the conveying path of the conveying apparatus, and the apparatus can be made compact.
