Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet conveying apparatus for conveying paper sheets such as postal letters, and more specifically,
The present invention relates to a paper sheet transporting device that can sort and transport continuously transported paper sheets to a plurality of transport paths.

[0002]

2. Description of the Related Art For example, in a postal letter automatic arranging and stamping machine or the like, a stamp or an address bar code attached to a postal letter, a postal letter, or the like which is continuously conveyed is detected and stamped. It is divided into express delivery and ordinary mail.

Therefore, in this kind of apparatus, it is necessary to sort the continuously conveyed postal letters into a plurality of conveying paths and convey them in a predetermined direction, for example, to a sorting stacking box.
In this type of paper sheet conveying apparatus, the paper sheet is held and conveyed by a belt, so that at least two branching rollers around which the conveyance belts are provided are provided around the branching portions of the two conveying paths. Above, there is a gap between these branching rollers.

On the other hand, looking at the shape of the paper sheets before they are supplied, it cannot be said that they are always kept flat because the tips are bent or curled paper sheets are mixed. like this,
When the leading end is bent or a curled paper sheet is conveyed, the paper sheet sometimes enters the gap between the branching rollers and causes the paper sheet to remain.

Therefore, conventionally, in order to close the gap between the branching rollers, the front portion of the gap is shielded.
It had a fixed guide plate. However, in the case of such a configuration, although the front surface of the gap can be shielded, the guide plate cannot be brought into contact with the conveyor belt, and a gap is formed between the rear surface of the guide plate and the conveyor belt. As a result, the leading edge of the paper sheet may enter the back side of the guide plate. Further, when the paper sheets being conveyed collide with the guide plate, the conveyance speed is changed, which may cause the conveyance failure.

[0006]

As described above, in the conventional conveying device provided with the guide plate, it is impossible to reliably prevent the paper sheets from staying at the branch portions of the two conveying paths. In addition to the risk of damaging the paper sheets, the device must be stopped and the jammed paper sheets must be removed, and the removal work is troublesome and burdens the operator. There is a problem that the operating efficiency of a device equipped with the device is lowered.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to reliably distribute and convey paper sheets to two conveying paths without retaining the paper sheets at a branching portion. Provided is a paper sheet conveying device capable of preventing damage to a paper sheet due to clogging at a branch portion, reducing the burden on an operator, and improving the operation efficiency of a device equipped with this conveying device. Is.
