[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper sheet binding device for winding a tape around an outer periphery of a plurality of paper sheets having the same size and the same shape and bundling them.

[0002]

[Prior art]

 Conventionally, for example, Japanese Patent Application Laid-Open No. 60-58312 discloses a binding device for binding a predetermined number of sheets having the same shape and size such as banknotes and binding them with a tape. The binding device described in this publication has a paper sheet insertion opening on the front surface of the main body of the apparatus, and an annular rotary wheel corresponding to the binding position of the paper sheets inserted and positioned through this insertion opening. Are arranged so as to surround the paper sheets, and the rotating wheel is provided with a winding member (roller) for winding the binding tape around the paper sheets. A bundling tape is wound around the outer circumference of the class and tension is applied to the tape, and then the tape is cut by a cutting device, and the cut end is adhered by an adhesive trowel.

However, in the above-mentioned conventional apparatus, a rotating wheel for winding the tape at the binding position of the paper sheets is provided at the binding position, and the paper sheets are inserted therein, so that it is inevitably rotated. Since the inner diameter of the ring increases and the outer diameter increases accordingly, the overall size of the device becomes large and the device cannot be made compact.

Therefore, the applicant holds the tip of the tape sent from the tape supply means with the tip of a swivelable arm, and swivels the arm to wait a position above the installation position of the tape supply means. After the paper is inserted, the paper is inserted and swirled to wind the tape around the paper, and then the paper on both sides of the tape winding part is compressed and held, and then the tape is tightened. , A paper sheet bundling device (Japanese Patent Application No. 3-25721) having an arm rotation type tape winding means for bundling paper sheets by cutting and adhering.

[0005]

[Problems to be solved by the device]

 With the above-described paper sheet binding device, however, the problems of the above-mentioned known technology can be solved, but with this device, after the paper sheets are inserted, they are not fixed by the holding means or the like. In other words, while the operator holds the paper sheet in his hand, the arm of the tape wrapping means swivels from the standby position to the rest of the area to wrap the tape around the paper sheet. There were problems that the paper sheets moved and the tape could not be wound correctly, and that the operator had to bind the paper sheets while holding them, and the operability was poor. Further, even if the paper sheet is held immediately after the insertion of the paper sheet, the holding means cannot be provided in the area in which the arm of the tape winding means pivots from the standby position and on the base side of the arm. If the leaf has a crease, or if it is a loose paper sheet such as a used banknote, it is not self-supporting, and as a result, the arm folds the paper sheet together when the arm rotates. Therefore, there is a problem that normal binding cannot be performed.

In view of the above, the present invention has been made such that the paper sheets are accurately wrapped and bound by simply inserting the paper sheets into the binding position, and even if the paper sheets are folded or the waist is weak. The purpose of the present invention is to provide a paper sheet binding device that enables normal binding without folding the paper sheets.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems of the conventional technique, the present invention wraps a tape fed from a tape feeding means around a large number of stacked paper sheets and cuts the tape end with a cutter. In a paper sheet binding device for binding paper sheets by heat bonding with an adhesive iron, a holding means for holding both side surfaces of the paper sheets inserted at a binding position, and a tip of the tape fed from the tape supply means. It has an arm that can be swung while holding the paper sheet and waits at the standby position above the installation side of the tape feeding means to insert the paper sheet and the paper sheet is held by the holding means. After that, the paper sheet bundling device having a tape winding means for further turning and winding the tape around the paper sheet is referred to as claim 1, and is provided above the tape supply means installation side and Of the arm of the tape winding means Is provided so as to be swingable on the side where the section is located, and when the arm is located at the standby position, it is located outside the insertion path of the paper sheets, and the arm is biased by a spring before the end of tape winding. According to a second aspect of the present invention, there is provided a paper sheet binding device including a paper sheet pressing mechanism having a paper sheet pressing lever for pressing the upper side surface of the leaves.

[0008]

[Action]

 Before the sheets to be bound are inserted, the arm holding the tape end is located at the upper standby position on the side opposite to the tape supply section, and at this time, the pressing lever moves the sheet insertion path. It is placed in a position that is off. As soon as the paper sheets are inserted into the binding position, both sides of the paper sheets are pinched by the pinching means, and at that stage, the operator can release the paper sheets. Then, since the arm rotates around the paper sheet fixed by the holding means to wind the tape, the tape can be wound accurately without slipping. Also, before the arm finishes winding the tape, the pressing lever presses the upper side of the paper sheet, and the paper sheet may be folded or the upper edge of the paper sheet may come apart even if the waist is lost. To prevent the tape from being wound. When the arm returns to the standby position after bundling is completed, the pressing lever is returned in the middle and retracts to a position that does not hinder the insertion of the next sheet.

Then, the paper sheet detection plate 62 is pushed by the tip of the paper sheet, which causes the shaft 57 to retreat and the swing lever 67 to swing. This is detected, and the bundling operation is started by the detection signal.

When a binding operation start command is issued, the shutter plate 136 of the shutter mechanism 135 is first closed, and then the swing mechanism (not shown) rotates the relay mechanism 35 counterclockwise in FIG. It moves to the side and the rollers 18 and 28 of the arm 15 and the link 24 are pushed outward by the left and right cam surfaces 20 and 29.

When the cam member 19 moves to the back side, the first and second holding members 5 and 6 move in a direction in which they approach each other, and this movement causes the holding surfaces 8, 9, 11, and 12 to move the paper. Hold both sides of the leaf P (Figs. 5 and 16).

After that, the arm 51 of the tape winding means 50 re-rotates, and at that time, the trimming piece 110 of the tape trimming plate 106 is pushed away and passed, while the actuating lever 112 of the paper sheet pressing mechanism 111 is moved as shown in FIG. When the arm 51 is placed along the paper sheet P and passes through the lower part of the arm 51, the holding of the operating lever 112 is released as the arm 51 passes and the pressing lever 116 is released. Is rotated counterclockwise in the figure by the action of the spring 119, and the pressing portion 114 presses the upper side portion of the paper sheet P, and adjusts the variation above the paper sheet P (FIG. 18).

Then, the roller 34 of the lever 13 is rotated by the crank-shaped long hole 39 of the member 40 of the relay mechanism 35, and the lever 13 is rotated to bring the third holding member 7 into contact with the paper sheet P (see FIG. 6). . As a result, both side surfaces of the paper sheet P are held by the holding surfaces 8, 9, 11, 12, 32 of the holding members 5, 6, 7 (FIG. 19).

Then, the roller 102 of the tape supply means 100 reverses to apply tension to the tape T (FIG. 20), the iron 150 moves forward and presses the overlapping portion of the tape T, and at the same time when this adhesion is started, the cutter 156 descends. Then, the tape T is cut, and the cutting end of the tape T is rubbed up by further advancing the iron 150 to heat-bond it (FIG. 21).

Thereafter, the cutter 156 and the iron 150 return to their original positions, the moving frame 56 is retracted by the moving mechanism 69, the arm 51 is pulled out from the tape bonding position, and the binding of the paper sheets is completed. Then, the cam member 19 also returns to the initial position, the holding members 5, 6 and 7 are opened to the initial position, the holding of the paper sheets is released, and the shutter plate 136 is opened to close the bound paper sheets. It can be taken out.

When the bundled paper sheets are taken out, the shutter plate 136 is closed again and the arm 51 returns to the tape receiving position. Then, the roller 102 of the tape supply means 100 is once rotated in the reverse direction and then forwardly rotated to feed the tape T, and similarly to the above, it is held by the arm 51 and swung to the standby position, and the standby state shown in FIG. 15 is obtained.

[Effect of device]

 As described above, according to the present invention, the arm holding the tape end is swung around the paper sheets to be inserted at the binding position, the tape is wound, and the wound end is cut and heat-bonded. In the binding device that binds the sheets together, both sides of the sheet are held by the holding means as soon as the sheets are inserted into the binding position, so that the operator can remove the hands from the sheets and the operability is improved. . Further, since the tape is wound while the paper sheet is held and fixed by the holding means, the tape is prevented from being displaced and the tape is wound accurately. Moreover, before the arm finishes winding the tape, the upper side surface of the paper-like material facing the swivel trajectory of the arm of the tape winding means is pressed by the paper-sheet pressing lever, so that the paper-like material with a weak waist is pressed. However, it does not bend due to contact with the tape, and thus does not cause defective binding. Furthermore, since the presser lever uses the pivoting motion of the arm to perform presser operation and presser release, there is no need to install a special drive mechanism, and a simple structure and reliable presser operation and binding are not required. It has various excellent effects such as being able to perform the above and being easily incorporated into the binding device.
