DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. The finned sheet conveying apparatus to which the present invention is applied is similar to the conventional conveying apparatus shown in FIG. 3 in that finned conveying belts 3 are disposed on both sides of a conveying table 1 having an upper surface as a conveying area. A gate (not shown) is provided on the downstream side, and the discharge roller 6 is further disposed downstream of the gate. The fins 2 are placed on the surface of the conveyor belt 3 at positions spaced apart by a half of the circumference.
Is protruding.

According to the present embodiment, as shown in FIG. 1, the transport table 1 has two parallel to the upper surface of the transport table 1 that penetrates the transport table 1 in a width direction perpendicular to the transport direction. The rotating shafts 10 and 11 are arranged at intervals along the carrying direction of the carrying table 1, and are located at a position downstream and below the rotating shaft 10 of the carrying table 1 that penetrates the carrying table 1 in the width direction. A rotation shaft 12 parallel to the upper surface is provided, and a drive pulley 7 of the conveyance belt 3, a support pulley 8 of the conveyance belt 3, and a driven pulley 9 of the discharge roller 6 are attached to these rotation shafts 10, 11, and 12, respectively.
The finned conveyor belt 3 is wrapped around the pulleys 7, 8, and 9.

The discharge roller 6 comprises a pair of an upper roller 6a and a lower roller 6b, and two pairs are provided. The lower roller 6b is
It is attached to the rotating shaft 12 of the driven pulley 9 at an interval, and the top faces the opening 15 provided at the transport table 1 at an interval in the width direction. A support 17 for supporting the upper roller 6a is swingably supported around a support shaft 16 fixed to a frame portion (not shown) of the transport device, and is spaced apart from the support shaft 16 in the longitudinal direction. Fixed. Further, the upper roller 6a is rotatably supported by the support member 17. The upper roller 6a is in light pressure contact with the lower roller 6b due to its weight. According to the present embodiment, the lower roller 6 b is formed to have a larger diameter than the driven pulley 9. The diameter of the lower roller 6b is determined on the basis of the minimum top and bottom width of the form 20 to be used (the length of the side in the same direction as the transport direction) so as to obtain a speed that does not involve the rear end of the form 20. .

A stepping motor 13 is used as a drive source of the transport belt 3 and is connected to a rotary shaft 10 on which a drive pulley 7 is mounted. That is, the pulley 14 is attached to the tip of the rotating shaft 10 protruding from the drive pulley 7, and the drive belt 18 is wound around the pulley 14 and the pulley 21 attached to the output shaft of the stepping motor 13. Accordingly, when the rotating shaft 10 is rotated by the stepping motor 13 via the drive belt 18 and the pulley 14, the drive pulley 7 attached thereto is rotated,
The conveyor belt 3 is driven to rotate in the direction of the arrow by the pulley 7. The rotation of the transport belt 3 rotates the support pulley 8 and the driven pulley 9, and the rotation of the driven pulley 9 drives the lower discharge roller 6 b attached to the rotating shaft 12. Since the diameter of the lower roller 6b is larger than that of the driven roller 9, the lower roller 6b
Is higher than the peripheral speed of the driven roller 9. That is, the transport speed of the discharge roller 6 with respect to the form 20 is higher than the transport speed of the transport belt 3.

As shown in FIG. 2, the fins 2 of the conveyor belt 3 move to the support pulley 8 along the upper surface of the conveyor table 1 by the rotation of the conveyor belt 3, and when the fins 2 pass through the support pulley 8, they assume a forwardly inclined posture. As a result, the vehicle travels gently at an angle up to the driven pulley 9. Thereafter, the pulley 9 rotates along the circumference of the pulley 9, moves substantially parallel to the drive pulley 7 in a downward position, and rotates around the pulley 7 to make an upward position.

Forms 20 loaded on the transport table 1
Is pushed downstream of the fin 2 by the fins 2 of the conveyor belt 3 and transported to the downstream side, and the front end collides with a gate (not shown) to adjust the posture. Thereafter, by raising the gate, the form 20 pressed by the fins 2 is sent to the transport roller 6 and is discharged from the transport table 1 by the transport roller 6. At this time, since the transport speed of the discharge roller 6 is higher than the transport speed of the transport belt 3, the fin 2
Even if the sheet passes through the support pulley 8 and leans forward, the form 20 sent to the discharge roller 6 is quickly conveyed, and the form 2
0 is not left at the position of the fin 2, so that the rear end of the form 20 does not get caught and hit by the fin 2 which tilts forward, and the loaded form 20 is twisted or wrinkled. Can be prevented, or the posture can be prevented from being disturbed.

The fins 2 of the transport belt 3 assume a forwardly inclined posture when passing through the support pulley 8, but do not change to a sharply downward posture as in the case of making one round around the pulley. Therefore, it is difficult for the rear end of the form 20 to be caught in the fins 2.
It is not necessary to increase the transfer speed of the transfer belt 3 compared to the transfer speed of the transfer belt 3, and there is an advantage that the transfer stability of the discharge roller 6 is not impaired.

The present embodiment is configured as described above, and has the following operational effects. (1) Convey belt 3 on driven pulley 9 of discharge roller 6
, The discharge roller 6 can be driven by the drive source of the conveyor belt 3, and one drive source of the apparatus can be omitted. (2) Since the diameter of the discharge roller 6 is larger than the diameter of the driven pulley 9 of the discharge roller, the speed at which the sheet is conveyed by the discharge roller 6 can be higher than the speed at which the sheet is conveyed by the conveyor belt 3, and the fins 2 Even if the sheet is tilted forward, the sheet fed to the discharge roller 6 is quickly conveyed, so that the trailing end of the sheet is prevented from being caught and hit by the fin 2 tilted forward. (3) Since one drive source can be omitted, the device configuration can be made compact, and the entire device can be downsized.

In the above embodiment, the stepping motor 13 of the driving source is connected to the rotating shaft 10 to which the drive pulley 7 of the conveyor belt 3 is attached. However, the present invention is not limited to this, and the driving source is The lower roller 6b may be connected to the rotating shaft 12 to which the lower roller 6b is attached. Although two pairs of upper and lower rollers 6a and 4b are installed as the unloading roller 6, one pair of upper and lower rollers having a wide width may be installed. The upper member does not necessarily need to be a roller, and the lower roller 6b
It may be a pressing member which is arranged so as to swing freely and comes into contact with the light pressure. In some cases, the upper member may be omitted. Further, the rotation speed of the rotary shaft 12 is increased by interposing a gear mechanism in the middle of the rotary shaft 12 to which the driven pulley 9 is attached, so that the lower roller 6b is transported by the discharge roller 6 without having a larger diameter than the driven pulley 9. The speed may be higher than the transport speed of the transport belt 3. Although the conveyed articles are forms such as various kinds of payment statements of banks and the like, and usage statements of telephones and the like, any sheet that needs to be conveyed in a generally adjusted posture can be conveyed.

[0024]

According to the first aspect of the present invention, the following effects can be obtained. (1) The discharge roller can be driven by the drive source of the transport belt, and one drive source of the apparatus can be omitted. (2) Even if the fins are tilted forward, the sheet fed to the discharge roller is quickly conveyed, so that the trailing edge of the sheet is prevented from being caught and hit by the fins tilted forward. (3) Since one drive source can be omitted, the device configuration can be made compact, and the entire device can be downsized.

According to the second aspect of the present invention, the structure of the speed increasing means of the discharge roller is simple.
