Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a binding tape insertion device in a paper sheet binding device for binding paper sheets such as banknotes, securities, lottery tickets, postcards, and various card-like sheets.

Conventionally, a tape insertion device of this type has been proposed, for example, as described in Japanese Patent Publication No. 11914/1983. The already proposed tape insertion device includes a thin tongue-shaped tape insertion plate that can move forward and backward between the leaves of paper sheets and support a binding tape that can be freely fed out on the upper surface, and this tape insertion plate. Using a guide member which is synchronously preceding and capable of forming a gap for inserting a tape insertion board between the leaves, the spaces between the sheets to be bound are pushed apart by the preceding action of the guide member, and this pushed open The tape insertion plate is inserted into the gap along with the tape.

However, the already proposed tape insertion device described above has an extremely complicated mechanism in which the tape is supported on the top surface of the tape insertion plate and inserted between the leaves. However, due to the frictional force generated between the tape and the tape insertion plate, it is impossible to exclude the possibility that the inserted tape will be tangled back from between the leaves. In this way, if the leading end of the tape is pulled back from between the leaves, it becomes impossible to wind the tape, or the tape becomes loose and sag after winding.

An object of the present invention is to enable the leading end of the tape to be reliably inserted between the leaves using an extremely simple mechanism.

In order to achieve the above object, the binding tape insertion device in the paper sheet binding device according to the present invention is provided with a tape insertion device that is divided into two states, a widened state and a flattened state, between the leaves forming the tape insertion portion of the paper sheets. The members are arranged relative to each other, and the tip end of the tape is individually inserted into the tape insertion gap formed between the leaves when the dividing member is in an expanded state.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a schematic configuration of a paper sheet binding device 10 used for carrying out the present invention. This paper sheet binding device 10 allows a large number of stacked paper sheets 11 to be inserted into a binding position defined by a window hole 12, and also allows paper sheets to be inserted on both sides of the binding position as shown in FIG. Move toward and away from both sides of Class 11,
a holding member 13 that can press and hold paper sheets 11;
It has 14.

The paper sheet binding device 10 also includes a tape reel 16 loaded with a long heat-welded tape 15 for binding, two tape feed rollers 17 that are rotated as appropriate, a tape feed guide 18, and a tape cutting blade. 1
9, the leading end of the tape 15 is fed between the leaves forming the tape insertion portion of the paper sheet 11 by a mechanism to be described later, and the tape 15 can be fed around the paper sheet 11. There is.

Further, the paper sheet binding device 10 has a revolving body 20 that rotates around the binding position, and the revolving body 20 includes a pair of tape support members 21 and 22. When the rotating body 20 into which the leading end of the tape 15 is inserted is stationary, the tape supporting members 21 and 22 listen to each other to define a feeding path for the tape 15 between them, as shown in FIG. When the body 20 rotates, as shown in FIG. 2, the tape 15 closes between them.
This makes it possible to wrap the tape 15 around the paper sheet 11 and the holding members 13 and 14 by sandwiching them.

Further, the paper sheet binding device 10 has a tape adhesion heater 23, and the tape adhesion heater 23 has a third
As shown in the figure, paper sheets 11 and holding members 13,
The end portion of the tape 15 wound around the tape 14 is pressed against the holding member 13 to enable welding.

Thus, the paper sheet binding device 10 has a tongue-like dividing member 24 arranged approximately at the center of the binding position.
As shown in FIG.
It is located inside the machine from the insertion and winding position of 5, and can collide with the leading end of the paper sheets 11 inserted at the bundling position. Here, the dividing member 24 is
At the stage when the paper sheets 11 are inserted into the bundling position, the paper sheets 11 are placed in the solid line state in FIG. 1 and in the widened state perpendicular to the surface of the paper sheets 11 as shown in FIG. Waiting for the collision with the tip side, insert the sharp end 24A between the leaves forming the tape insertion part of the paper sheet 11, divide the paper sheet 11 into a V shape, and insert a wide space between the leaves. A tape insertion gap 25 can be formed. Further, after the above, the dividing member 24 is
As shown in the two-dot chain line state in the figure and in FIG.
The tape 15 is rotated once to eliminate the tape insertion gap 25 and to hold the tape 15 in close contact between the leaves.

Next, the operation of the above embodiment will be explained.

At the same time that the paper sheets 11 are inserted into the bundling position through the window hole 12, the paper sheets 11 are inserted into the paper sheets 1 in the machine.
The tape is divided into a V-shape by a dividing member 24 waiting in an expanded state perpendicular to the surface of the tape 1, and a tape insertion gap 25 is formed. Following this, the tape reel 16 and tape feed roller 17 rotate, and the leading end of the tape 15 is inserted alone into the tape insertion gap 25 of the paper sheet 11.

Next, the holding members 13 and 14 are driven to press and hold the paper sheet 11, and at the same time, the dividing member 24 is rotated 90 degrees from the widened state perpendicular to the surface of the paper sheet 11, and the paper sheet 11 is Transition to a flat state parallel to the surface. As a result, the tape insertion gap 25 between the sheets 11 disappears, and the leading end of the tape 15 is held in close contact between the sheets 11.

Next, the paper sheets 11 are rotated by the rotation of the revolving body 20.
Then, the tape 15 is wound around the holding members 13 and 14, and the end portion of the tape 15 is cut by the tape cutting blade 19. In this way, paper sheets 11 and holding members 13, 14
When a predetermined length of tape 15 is wound around the
The end portion of the tape 15 is welded by a tape bonding heater 23. Thereafter, by pulling the paper sheets 11 out of the machine, the paper sheets 11 bound by the tape 15 can be obtained.

That is, according to the above embodiment, the tape 15
The tape is inserted completely independently into the wide tape insertion gap 25 formed between the paper sheets by the dividing member 24 by the tape feed roller 17 which is rotationally driven as appropriate, and then the tape insertion gap 25 is disappeared. The paper sheets 11 are held in close contact with each other between the leaves, and the paper sheets 11 are held very reliably between the leaves without being subjected to any pullback action after being inserted into the spaces.

In the above embodiment, the tape 15 is wound around the paper sheets 11 without rotating the paper sheets 11 in the binding device. However, the present invention is also applicable to the case where the tape is wound around the paper sheets by rotating the paper sheets at the binding position.

Further, in the above embodiment, a case was described in which a tongue-shaped dividing member that rotates 90 degrees is used. However, the present invention does not require the use of dividing members having other shapes and structures as long as the dividing members can substantially form two states, a widened state and a flattened state, between the leaves of paper sheets. It's okay to be hot.

The binding tape insertion device in the paper sheet binding device according to the present invention as described above has a dividing member relatively arranged between the sheets forming the tape insertion portion of the paper sheets,
When the width of the dividing member between the leaves is widened, the tip of the tape is individually inserted between the leaves forming a tape insertion gap. Therefore, the tape can be reliably inserted between the sheets of paper with an extremely simple mechanism.
