[0017]

BEST MODE FOR CARRYING OUT THE INVENTION A feeding / conveying belt according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 11.

In FIG. 1, a delivery belt 10 wound around a driving roller 12 and a driven roller 14 is provided. Although not shown, the drive roller 12 is connected to a drive mechanism and is configured to be rotationally driven by the drive force of the drive mechanism.

The lower surface of the feeding belt 10 is arranged in contact with the sheets P stacked on the tray 16,
The feeding belt 10 is rotated by the rotation of the drive roller 12, whereby the surface of the feeding belt 10 and the paper P are rotated.
The uppermost sheets of the sheets P stacked on the tray 16 are fed one by one by the frictional force between the sheets.

As shown in FIG.
As shown in FIGS. 4 to 4, a large number of dimples D are provided. The dimple D is formed from a recess having a diameter of 0.5 to 10.0 mm and a depth of 0.1 to 5.0 mm. Due to the recess of the dimple D, the lower surface of the feeding belt 10 is covered with the paper P. When it comes into contact with the sheet P, the sheet P is elastically deformed and comes into close contact with the sheet P, whereby the sheet P can be straightly and surely fed out without causing oblique sheet feeding.

The dimples D provided on the surface of the delivery belt 10 are provided on the entire surface of the delivery belt 10, but it is preferable to form the dimple pattern T having a certain regularity.

For example, as shown in FIG. 5, when the dimple patterns T are arranged in a grid pattern T1, the feeding belt 1
When 0 rotates, the paper P is provided with a flat portion 10a on the front surface of the feeding belt 10 and a dimple portion Da formed on the front surface.
However, since they abut alternately like Y1-Y2-Y3,
The paper P can be reliably fed in the transport direction.

As shown in FIG. 6, when the dimple patterns T are arranged in a zigzag pattern T2, the feeding belt 10
When the sheet P rotates, the sheet P has a flat portion 10a on the front surface of the feeding belt 10 and a dimple portion Da formed on the front surface.
However, since it is always in contact with Y5-Y6-Y7, the elastic force always acts in the conveyance direction and the width direction of the sheet P, which allows the wrinkles and the like to be extended at the same time as the sheet is conveyed.

Further, since the dimples D are formed from the dents, as is clear from FIG. 4, the paper dust X or the like generated during the feeding of the paper once enters the dents of the dimples D, so that the paper Since it suppresses the diffusion of powder and does not have walls and edges (corners) unlike the conventional recesses, the paper powder X that has entered the recess is easily removed from the inside of the recess of the dimple D. Therefore, as shown in FIG.
It is possible to stably feed the paper P without the need for cleaning the above or replacing the feeding belt 10.

Therefore, by the action of the flat surface portion 10a of the feeding belt 10 on which the dimples D are formed and the dimples D arranged in the predetermined dimple pattern T, the surface of the feeding belt 10 is brought into close contact with the paper P, whereby The paper P can be reliably and stably fed out without slipping.

The dimple D can be easily formed by dimple processing or die molding on the surface of the belt made of an elastic material such as rubber. As shown in FIG. 7, a sheet having the dimple D is formed. (Hereinafter, referred to as the dimple sheet DS) may be attached to the belt-shaped fibrous body.

When the dimple sheet DS is attached to the belt-shaped fibrous body, as shown in FIG. 8, the joint portion L2 of the dimple sheet DS2 is moved in the axial direction Y of the drive roller 12.
As shown in FIG. 7, it is preferable to bond the dimple sheet DS1 so that the joint portion L1 of the dimple sheet DS1 intersects the axial direction Y of the driving roller 12 rather than the bonding in parallel with.

As a result, peeling of the dimple sheet DS can be prevented and the work of attaching the dimple sheet DS can be simplified.

Next, as the constitution of the feeding belt,
As shown in FIG. 9, the feeding belt 30 having the dimples D is attached to the friction drive roller 34 and the pinch roller 3.
2 and the friction drive roller 34 and the pinch roller 32 rotate, so that the feeding belt 30
And the feeding belt 30 is rotated by its own weight so that the paper P
The sheet P can be configured to be fed one by one by contacting the surface of the sheet and rotating.

In this case, since the self-weight of the feeding belt 30 is used, an excessive load is not applied to the paper P. Therefore, even thin paper can be fed accurately and stably without damaging it. it can.

Further, as shown in FIG. 10, a weight member 36 having a weight selected in relation to the thickness and material of the fed paper P is provided inside the feeding belt 30 to adjust the pressing force against the paper. , Even if it is a special paper, it can be fed accurately and stably with a simple structure.

Further, as shown in FIG. 11, the driving friction roller 34 is provided inside the feeding belt 30 as a biasing means 39 for biasing the lower surface of the feeding belt 30 downward.
A lever 38 engaged with the shaft of the lever 38 and a biasing roller 37 locked at the tip of the lever 38, and when the drive friction roller 34 is driven, the lever 39 rotates,
The urging roller 37 is pressed downward, and the lower surface of the feeding belt 30 is brought into close contact with the paper by the pressing force. This makes it possible to apply a pressing force to the belt 30 only at the time of feeding, and to reliably feed the paper without applying an unnecessary load to the paper.
