Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet binding apparatus which cuts a wire into an appropriate length and uses it to bind paper sheets.

[0002]

2. Description of the Related Art FIG. 5 shows a wire feeder of a conventional paper sheet binding device. In the figure, a wire processing unit (not shown) is provided at the bottom of the device body 90,
A single wire support plate 94 is provided on the upper part of the so as to be rotatable around the vertical axis 92. This wire support plate 94
A wire 96 is supported around the vertical shaft 92 in a wound state, and the wire 96 is pulled out from the wire support plate 94 in the horizontal direction (left direction in FIG. 5).

A wire guide plate 97 is provided between the wire support plate 94 and the wire processing section. The outer surface of the wire guide plate 97 is a guide surface that guides the wire 96 to the wire processing unit while contacting the wire 96 pulled out from the wire support plate 94. Wire holding members 98 are provided at a plurality of positions on the guide surface, and each wire holding member 98 is provided with an insertion hole through which the wire 96 is inserted. The insertion hole of each wire holding member 98 is aligned with the guide direction of the wire 96, and the insertion hole of the most upstream wire holding member 98 is the wire 96 from the wire support plate 94.
It almost coincides with the drawing direction of.

In this device, when the wire 96 is pulled out from the wire support plate 94, inserted into the insertion holes of the wire holding members 98 and set in a wire processing unit (not shown), the wire is processed. The wire 96 is pulled in by the section,
After being cut into an appropriate length, the cut wire 96 is bent into an appropriate shape, generally a U-shape similar to that of a normal staple (binding staple), and the wire 96 is used to cut a paper sheet. The binding work is done.

Here, since the wire 96 is drawn into the wire processing section, the wire 96 is pulled out from the wire support plate 94, and the wire 96 slides on the guide surface of the wire guide plate 97. When the wire 96 slides on the curved portion of the wire, the winding of the wire 96 is corrected.

[0006]

In the above device, the wire 96 used depends on the number and hardness of the sheets to be bound.
It is necessary to change the thickness of the wire (that is, replace the wire 96). In order to carry out such exchange, all wire holding members 98
After pulling out the wire 96 from the insertion hole of the wire in the opposite direction and removing the wire 96 from the wire support plate 94, the wire 96 having a diameter different from that of the wire 96 is set again on the wire support plate 94 in a wound state. Each wire holding member 9 is pulled out from 94.
It is necessary to carry out a troublesome work such as inserting it into the insertion hole of No. 8, which requires a great deal of time and labor.

As a means for eliminating such inconvenience,
As shown by the chain double-dashed line in FIG. 5, another wire support plate 94 is stacked on the wire support plate 94, and another wire (wires having different diameters) 96 is set on the wire support plate 94. It is conceivable to select and use a suitable one of the wires 96. However, in this configuration, the direction in which the wire 96 is pulled out from the upper wire support plate 94 toward the most upstream wire holding member 98 is largely deviated from the direction of the insertion hole of the wire holding member 98 (two points in FIG. (See the chain line), the wire holding member 98 on the most upstream side bends the wire 96 remarkably, and rather bends the wire 96. When the wire 96 is supplied to the wire processing unit while such bent habit remains on the wire 96, the wire 96 is cut into pieces by the wire processing unit, and then the wire 96 is prevented from being deformed into a suitable shape. , The smooth binding work of paper sheets may be hindered. Such inconvenience similarly occurs when the wire support plates 94 are arranged side by side in the horizontal direction.

In view of such circumstances, the present invention makes it possible to selectively use a plurality of types of wires in a paper sheet binding device using wires without giving an unfavorable habit to the wires, thereby improving work efficiency. The purpose is to raise.

[0009]

As a means for solving the above problems, the present invention provides a wire support part for supporting a wire in a wound state, and a wire supplied from the wire support part to a predetermined length. A wire processing unit that cuts and binds paper sheets with this wire, and a guide surface that is provided between the wire supporting unit and the wire processing unit and that guides the wire pulled out from the wire supporting unit to the wire processing unit. And a wire guide member having
In a paper sheet binding device provided with a wire holding member having insertion holes through which the wire is inserted at a plurality of positions on the guide surface, a plurality of wire support portions are arranged at different positions, while the wire guide member is provided. The inlet end of the wire is branched toward each wire support portion, the wire holding members are provided at each branch portion, and the directions of the insertion holes of these wire holding members are substantially aligned with the wire withdrawing direction from the wire support portion. (Claim 1).

In this apparatus, at least one wire support portion is configured to be movable with respect to the apparatus main body in a direction orthogonal to the wire winding center axis, and the wire support portion is allowed to move and the wire support is provided. It is more preferable to provide a fixing means capable of switching to a fixed state for fixing the portion at an arbitrary position (claim 2).

More specifically, an arm is attached to the main body of the apparatus so as to be rotatable around a bolt in a direction substantially parallel to the wire winding center axis of the wire support portion, and the wire support portion is attached to the tip of the arm. A structure in which the pivot position of the arm is fixed by mounting the bolt and fixing the bolt is preferable.

[0012]

In the apparatus according to the first aspect of the present invention, if wires of different types (for example, different diameters) are set on the plurality of wire support portions, then a suitable wire is selected from these wires. The paper sheet binding operation can be started simply by inserting the sheet into the through hole of the wire holding member and setting it in the wire processing section. Therefore, the wires to be used can be switched without removing the wires from the wire support parts, and the work of attaching and detaching the wires to and from the wire support parts is not necessary. Moreover, the upstream end of the wire support member is branched and directed to each wire support portion, and the insertion holes of the wire holding member provided on the guide surface of each branch portion are respectively connected to the wire support member from each wire support portion. Since it is almost the same as the wire withdrawing direction, no strange bending habit is given to each wire.

Here, when the winding diameter or winding direction (right-handed or left-handed) of the wire set on the wire support is changed, the wire is withdrawn from this wire support toward the most upstream wire holding member. However, if the wire support portion is configured to be movable with respect to the apparatus main body in a direction orthogonal to the wire winding center axis as described in claim 2, this movement causes the wire to be withdrawn and the uppermost stream. It is possible to match the direction of the insertion hole in the wire holding member on the side, and by fixing the position of the wire support portion with the fixing means in such a matched state, bending is not given to the wire. The binding work can be performed.

More specifically, in the apparatus according to claim 3,
With the bolt loosened, the wire support part can be moved by rotating the arm around this bolt as a fulcrum, and after adjusting the position of the wire support part, tightening the bolt allows the arm to move. The position of the wire support can be fixed.

[0015]

The binding device 36 includes a housing 39,
The housing 39 is arranged on the front surface of the apparatus body 10. The housing 39 includes a shaft 40 in the left-right direction.
A wire gripping member 42 is attached so as to be rotatable around. A groove 44 that opens rearward (to the right in FIG. 3) is formed at the lower end of the wire gripping member 42.
The wire 18 (28) can be inserted therein, and the gripping mechanism for gripping the wire 18 (28) has a wire gripping member 42.
Is built into.

In the housing 39, column members 46 are held on both sides of the wire gripping member 42 so as to be able to move up and down.
A wire push-out plate 48 is held so as to be capable of moving up and down behind the wire gripping member 42, and the inner surface of each column member 46 is shown in FIG.
A groove 47 is formed as shown in (a) and (b).

The operation of the binding device 36 will be described later. Further, in the present invention, it is possible to substitute various ones used in the conventional sheet binding device regardless of the specific configuration of the wire processing unit.

A lower end portion of the wire guide plate 50 is provided at the wire entrance portion of the habit removing table 30. The wire guide plate 50 has a common portion 52 extending upward from the wire inlet portion.
And a branch portion 53, 54 that branches from the upper end of the common portion 52 to the left and right while bending to the horizontal direction. The outer surface of the wire guide plate 50 serves as a guide surface for guiding the wire 18 (28) supported by the reel 16 and the wire support plate 26 to the habit removing table 30.

One branch portion 53 faces the reel 16 and the other branch portion 54 faces the wire support plate 26. Wire holding members (most upstream wire holding members) 55 and 56 are provided on the outer surfaces (guide surfaces) of the branch portions 53 and 54, respectively.
The plurality of wire holding members 58 are vertically arranged side by side on the outer surface (guide surface) of the common portion 52.

Each wire holding member 55, 56, 58 is provided with an insertion hole through which the wire 18 (28) can be inserted.
The insertion hole of the wire holding member 58 is in the vertical direction, and the insertion holes of the wire holding members 55 and 56 are aligned with the branching directions of the branch portions 53 and 54, respectively. Therefore, the direction of the insertion hole of the wire holding member 55 is substantially coincident with the direction of pulling out the wire 18 from the reel 16. In addition, the wire 28 from the wire support plate 26 toward the wire holding member 56.
The positions of the arm 22 and the wire support plate 26 are adjusted so that the pull-out direction of the wire substantially coincides with the direction of the insertion hole of the wire holding member 56 (solid line position in FIG. 1).

The procedure for using this device will be described. First, among the wires 18 and 28, a wire suitable for the number of sheets 37 to be bound (binding thickness) and hardness is selected. For example, when the wire 18 is selected, as shown in the figure, the wire 18
The wire holding member 55 by pulling the wire horizontally from the reel 16.
Then, the wire holding member 58 is inserted through the insertion hole, and the pull-out end of the wire holding member 58 is set on the habit removing table 30. At this time, the unused wire 28 may be pulled out from the wire support plate 26 and inserted only into the wire holding member 56.

When the device is operated from this state, the wire 2
The binding work using 8 is automatically performed in the following procedure.

The wire feeding device 32 rotates upward from the position shown in FIG. 2, and the wire gripping portion 32a at the lower end thereof grips a predetermined portion of the wire 18.

The wire feeding device 32 is rotated downward while holding the wire 18, and while pulling the wire 18, the end thereof is inserted into the groove 44 of the wire gripping device 42.
At this time, the wire 18 is pulled out from the reel 16 by the amount of rotation of the wire feeder 32, and the wire 18 slides on the guide surface of the wire guide plate 52.
By sliding on the guide surface at the upper curved portion,
The curl of the wire 18 is corrected. Further, the wire 18 passes through the habit removing roller 31 in a zigzag shape, whereby the correction is further advanced.

The amount of rotation of the wire feeding device 32 (that is, the wire feeding length) is set according to the type of the paper sheet 37 (that is, in accordance with the required length of the binding wire 18).

The wire gripping device 42 operates to grip the portion of the wire 18 inserted in the groove 44. Then, the wire cutting device 34 lowers the knife 35 to cut the wire 18 into pieces of a predetermined length (state of FIG. 4A).

Both column members 46 descend from the above state.
At this time, the left and right wing portions of the wire 18 are fitted into the grooves 47 on the inner surface of the both pillar members 46, and are bent downward. That is, the wire 18 is bent in a U shape as shown in FIG.

The wire gripping device 42 releases the wire 18, and the wire push-out plate 48 descends while retreating to the front side (the front side in FIG. 4 (b)) (arrow in FIG. 4 (b)). Stick the wire 18 into the paper sheet 37, and
At 8, the paper sheets 37 are bound.

The above operations (1) to (5) are repeated to proceed with the binding work of the paper sheets 37. However, the binding thickness and hardness of the paper sheets 37 change during the process, and the wire to be used is changed from the wire 18 to the wire 2.
In the case of changing to 8, the wire 18 is pulled out from the insertion holes of the habit removing table 30 and the wire holding member 58 (it is not necessary to pull it out from the wire holding member 55), and instead, the wire 2 is used.
It suffices to insert 8 into the insertion hole of the wire holding member 58 and set it on the habit removing table 30. That is, it is not necessary to attach and detach the wires 18 and 28 to and from the reel 16 and the wire support plate 26 when changing the wire used, and the work efficiency is greatly improved.

Moreover, in this apparatus, the upper end of the wire guide plate 50 branches toward the reel 16 and the wire support plate 26,
Wire holding members 55, 5 provided on the respective branch portions 53, 54
Since the direction of the insertion hole of 6 is substantially coincident with the direction of withdrawing the wires 18, 28 to the wire retaining members 55, 56, the direction of withdrawing the wire 96 and the wire retaining direction are as shown by the two-dot chain line in FIG. Compared to the case where the direction of the insertion hole of the member 98 is deviated, the wires 18 and 28 do not have strange bending habits. Therefore, the deformation of the wires 18, 28 into a suitable shape (U-shape) due to such bending habit is not hindered,
Smooth binding work is guaranteed.

In the wire support plate 26, when the winding direction of the wire 28 is changed from the left winding to the right winding,
The direction of pulling out the wire 28 from the wire support plate 26 also changes, but in this case, the bolt 20 is once loosened and the arm 22 is rotated from the solid line position in FIG. 1 to the two-dot chain line position.
If the arm 22 is fixed by tightening the bolt 20 at this position, the pull-out direction of the wire 28 can be made to coincide with the direction of the insertion hole of the wire holding member 56 as in the case of the left-handed winding state, and the wire 28 is curled. Can be prevented. Further, even when the winding diameter of the wire 28 is changed, both directions can be matched by the same adjustment.

The present invention is not limited to such an embodiment, and the following modes can be taken as examples.

(1) In the above embodiment, the wire support plate 26 is horizontally moved by rotating the arm 22.
The wire support plate 26 may be attached to the apparatus body 10 so as to be horizontally slidable.

(2) In the above embodiment, the wire support plate 26
Alternatively, or in addition to the wire support plate 26, if the pulley 16 is configured to be movable in the vertical direction, even if the winding direction or winding diameter of the wire 18 on the pulley 16 is changed, the same handling as in the above embodiment is dealt with. It is possible. On the contrary, the positions of the wire support plate 26 and the pulley 16 may be completely fixed if the winding direction and winding diameter of the wires 18 and 28 are not changed.

(3) In the above embodiment, the positions of the pulley 16 and the wire support plate 26, which are wire support portions, are horizontally different, but these positions may be vertically different.
Moreover, you may make it provide three or more wire support parts. In these cases as well, by branching the upstream end of the wire guide plate 50 toward each wire support portion, the same effect as in the above embodiment can be obtained.

(4) In the present invention, the wire winding center axis of each wire support portion may be in any direction. For example, the wire winding center axis of the wire 18 may be oriented vertically in FIGS. Then
The winding axis direction of the wire 28 may be oriented horizontally.

[0045]

As described above, according to the present invention, since a plurality of wire support portions are arranged at different positions from each other, the wire to be used can be simply operated without attaching or detaching the wire to or from the wire support portion. It can be switched, and work efficiency can be significantly increased. Moreover, since the wire guide member is branched and the wire holding members on the most upstream side are provided at the respective branch portions, the direction of the insertion holes of these wire holding members is made to substantially coincide with the wire withdrawing direction from each wire supporting portion. Whichever wire is used, the wire can be supplied to the wire processing section without bending the wire, and there is an effect that the wire can be deformed into a preferable shape and a smooth binding operation can be ensured.

Further, in the apparatus according to claim 2, the wire support portion is configured to be movable with respect to the apparatus main body in a direction orthogonal to the wire winding central axis, and the position of the wire support portion is fixed. Since the fixing means that can be switched to the released state is provided, regardless of the winding diameter and the winding direction of the wire, the movement of the wire support portion causes the wire to be withdrawn and the insertion hole of the wire holding member on the most upstream side of the wire. There is an effect that the direction can be matched and bending of the wire can be prevented.

More specifically, in the apparatus according to claim 3,
The arm and the wire support part can be rotated and fixed only by loosening and fastening the bolt which is the fixing means, and the position of the wire support part can be adjusted with a simple structure.
