BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet binding apparatus for winding and bundling a tape around an outer periphery of a large number of sheets of the same shape and shape.

[0002]

2. Description of the Related Art Conventionally, there is a binding device disclosed in, for example, Japanese Patent Application Laid-Open No. 60-58312, in which a predetermined number of sheets having the same shape and size, such as banknotes, are stacked and bound with a tape. In the binding device described in this publication, a paper sheet insertion opening is opened in the front of the device main body, and an annular rotating wheel corresponding to the binding position of the paper sheet inserted and positioned from this insertion opening. Is disposed so as to surround the paper sheet, and a winding member (roller) for winding the binding tape around the paper sheet is provided on the rotating wheel. The binding tape is wound around the outer periphery of the kind and the tape is tensioned, and then the tape is cut by a cutting device, and the cut end is bonded by a bonding iron.

However, in the above-described conventional apparatus, a rotating wheel for winding a tape around the binding position of the paper sheets is provided at the binding position, and the paper sheets are inserted into the inside thereof. The inner diameter of the device becomes larger, and the outer diameter becomes larger accordingly, so that the entire device becomes larger and the device cannot be made smaller.

[0004] Therefore, the applicant holds the leading end of the tape sent from the tape supplying means with the leading end of a rotatable arm, and pivots this arm to set the standby position above the opposite side of the installation position of the tape supplying means. After the paper is inserted, the tape is further turned and the tape is wound around the paper.Then, the paper on both sides of the tape winding part is compressed and clamped, and then the tape is tightened and cut. Proposed a sheet binding apparatus (Japanese Utility Model Application No. 3-25721) having an arm-turning tape winding means for binding and binding the sheets.

[0005]

According to the above-described paper binding apparatus, the problems of the above-mentioned known technique can be solved. However, according to this apparatus, paper sheets are inserted. Thereafter, the arm of the tape winding means is rotated from the standby position to the remaining area while the tape is not fixed by the holding means or the like, that is, with the operator holding the paper sheet by hand, and the tape is wound on the paper sheet. As a result, the paper sheets move during the winding of the tape, and the tape cannot be wound correctly, and the operability is poor because the operator must bind the paper with the paper sheets. was there. Further, even if the paper sheet is immediately held after the insertion of the paper sheet, the holding means cannot be provided in a region where the arm of the tape winding means is turned from the standby position and at the base side of the arm. If the leaves are folded or the paper leaves are no longer rigid like a used banknote, there is no independence, and as a result, the arm will fold the paper sheets together when the arm turns. As a result, there is a problem that normal binding cannot be performed.

In view of this, the present invention takes into account the fact that the tape is wound exactly and bound by simply inserting the paper sheet into the binding position.
It is another object of the present invention to provide a sheet binding apparatus capable of normal binding without folding the sheet even if the sheet is folded or the waist is weak.

[0007]

SUMMARY OF THE INVENTION In order to solve the problems of the prior art, the present invention wraps a tape fed from a tape supply means around a multiplicity of stacked paper sheets. In a sheet binding apparatus for cutting sheets at the ends and bonding them by heat bonding with an adhesive trowel, a sheet holding apparatus for holding both sides of a sheet inserted at a binding position; An arm which is rotatable by nipping the leading end of the tape sent from the means, waits at a standby position above the side opposite to the side on which the tape supply means is installed, and paper sheets are inserted; A tape winding means for rotating the tape around the paper sheet after being held by the holding means and further turning the tape, and a side above the tape supply means installation side and on which the base of the arm of the tape winding means is located Swingable And a spring for urging the pressing lever in the sheet pressing direction, and a sheet pressing mechanism including an operating lever engageable with the sheet pressing lever. , The paper sheet pressing lever,
When the arm is located at the standby position, the arm is located outside the paper sheet insertion path via the operating lever pressed by the arm, and the engagement is released before the arm finishes winding the tape. The upper side of the leaf is pressed.

[0008]

The arm holding the tape end before the paper sheet to be bound is inserted is located at the upper standby position on the opposite side of the tape supply unit, and at this time, the pressing lever is moved to the position of the paper sheet. It is located off the insertion path. Immediately after the sheet is inserted into the binding position, both sides of the sheet are clamped by the clamping means. At this stage, the operator can release his / her hand from the sheet. Then, since the arm turns around the paper sheet fixed by the holding means and winds the tape, the tape can be wound accurately without slipping. In addition, before the arm finishes winding the tape, the pressing lever presses the upper side of the paper sheet, and the upper edge of the paper sheet may be dislodged even if the paper sheet is folded or the waist is lost. To prevent the tape from being wound. When the arm returns to the standby position after the binding, the pressing lever is returned halfway and retracts to a position that does not hinder the insertion of the next sheet.

In a binding device that binds together by heat bonding, as soon as the sheet is inserted into the binding position, both sides of the sheet are clamped by the clamping means, so that the operator can release his / her hand from the sheet, and the operability can be improved. Will be better. Further, since the tape is wound in a state in which the paper sheets are held and fixed by the holding means, the tape is prevented from slipping and the winding is performed accurately. Also, before the arm finishes the tape winding, the upper side of the paper facing the turning path of the arm of the tape winding means is pressed by the sheet pressing lever. Even if there is, there is no bending due to contact with the tape, and no bad binding occurs. Furthermore, since the presser lever performs the presser operation and presser release using the pivoting movement of the arm, there is no need to provide a special drive mechanism,
There are various excellent effects such as reliable pressing operation and bundling can be performed by a simple configuration without complicating the structure, and the incorporation into a bundling device is easy.
