Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip mounting device, and more particularly to a clip mounting device capable of selectively extruding a plurality of clips having different binding widths using a single clip mounting device.

[0002]

2. Description of the Related Art Conventionally, a pair of sandwiching pieces are provided on both sides of a spine forming a binding width, and a tip end side of the sandwiching pieces is gradually narrowed so that a sheet or the like can be bound by a spring-like metal. Sex clips are known and are available by using a dedicated clip applier.

In a known clip mounting device, a paper sheet insertion port is provided at the tip or front end side of a shaft-shaped case that can be grasped by a hand, and a clip holding piece portion is opened in the insertion port. A pair of bifurcated bifurcated bifurcated branch springs made of metal, bifurcated bifurcated bifurcated branch springs, a passageway for the clip leading to the insertion opening through the bifurcated bifurcation spring, and the back end of the clip at the leading edge, and the insertion opening It is configured to include an operation unit that can be further pushed out.

[0004]

However, most of the known clip mounting devices are manufactured corresponding to each clip having a specific binding width, and clips having different binding widths are used. Occasionally, a clip applicator that fits the clip must be used. Therefore, in order to be able to use different types of clips currently on the market, it is necessary to purchase at least a clip mounting device corresponding to each type, which is an economical burden. There is. Further, the single clip mounting device has a disadvantage that it is not versatile when binding documents having various binding widths and the application range is extremely limited.

Therefore, the applicant of the present invention is capable of arbitrarily selecting a plurality of types of clips having different sizes by using a single operation section, and extruding the selected clip by a slide operation of the operation section. A type clip mounting device has been proposed (see Japanese Patent Laid-Open No. 11-268465). The clip mounting device includes a main body case that has an insertion opening on the distal end side and extends in the axial direction, and a plurality of main body cases that are rotatably disposed in the main body case and that accommodate clips of different sizes and that extend in the insertion opening direction. And a pair of bifurcated branch springs arranged in the insertion port, and a piece-shaped holding body for holding these bifurcated branch springs.

In the holder, the bifurcated bifurcated spring is kept at the separated dimension position corresponding to the minimum clip width by the coil spring arranged between the holder and the main body case. A groove that allows passage of the middle and maximum clips is formed on the relative surface of the holding body, and the bifurcated branch spring resists the force of the coil spring when the clip passes through the groove. It is provided so as to be separated from each other and return to the minimum separated dimension position after the clip has passed.This makes it possible to pass clips of different sizes and push them out even if a pair of bifurcated branch springs are arranged. There is.

However, in the already proposed clip mounting device, since the holding member is mounted in the insertion opening via the above-mentioned coil spring, the mounting or assembling work is slightly complicated, and the holding member is There is still room for improvement in terms of improving the quality of mechanical parts and avoiding the cause of failure by stabilizing the posture of the robot.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to mount a holder for a bifurcated branch spring very easily, and
Another object of the present invention is to provide a clip mounter that is reliable enough to withstand long-term use while avoiding the cause of failure.

[0009]

In order to achieve the above object, the present invention comprises a back portion forming a binding width and a pair of holding piece portions which are connected to the back portion and face each other, and the holding piece is always provided. In the clip mounting device that is formed so that the tip ends of the parts are narrowed and that the paper sheets can be bound between the sandwiching piece parts by forcibly expanding this, a paper sheet insertion port is provided on the tip side. A main body case, a pair of bifurcated branch springs that are disposed in the insertion port and guide the clip while expanding the holding piece portions, and a pair of holding bodies that hold the bifurcated branch springs, A leaf spring member that is disposed between the holding body and the main body case and that always holds the holding body at a predetermined relative position; and two or more types that are rotatably housed in the main body case and have different sizes. Clip of the above two A holder member provided with a plurality of passages for guiding toward the base end side of the branch spring, and an actuating mechanism provided between the holder member and the holder, and when the holder member is rotated. The movement of the actuating mechanism changes the relative position of the holding body for each lateral width size of the clip so that the mutual separation width of the bifurcated branch springs can be adjusted. According to such a configuration, since the leaf spring is used, the leaf spring can be easily assembled, and the manufacturing efficiency can be dramatically improved. Further, since the separation width of the bifurcated branch spring is adjusted by changing the relative position of the holding body by the operating mechanism, the position of the bifurcated branch spring can be adjusted according to the size of the clip simply by changing the rotation angle of the holder member with respect to the main body case. Can be adjusted automatically. Therefore, unlike the clip applier proposed by the present applicant, when the clip is extruded, the separation width of the bifurcated bifurcated spring is not forcibly enlarged at the side edge of the clip, and therefore the extruding of the clip is performed. It is possible to allow smooth forward movement during operation, and it is possible to effectively prevent malfunctions and the like.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The actuating mechanism of the present invention comprises a cam shaft provided at the tip of the holder member, a cam provided on the cam shaft, and a cam shaft provided inside each of the holders. It is preferably configured by a cam contact portion that contacts the outer peripheral surface. According to this structure, the operating mechanism can be integrated with the holder member to have a simple structure, and the rotation of the holder member can be directly transmitted to the holding body, so that stable operation of the holding body can be achieved. Can be expected.

Further, the cam includes two cams provided at two locations along the cam shaft, and one cam contacts the cam contact portion of one holding body and the other cam holds the other. It is preferably provided to contact the cam contact portion of the body to independently adjust the position of each holder. With this configuration, when adjusting the separation width of the bifurcated bifurcated spring, the relative movement amount of the holding body can be kept equal, and as a result, the bifurcated bifurcated spring can always be positioned on the left and right ends of the clip. it can.

Further, the leaf spring member is seated in the main body case and lies in a direction substantially orthogonal to the axial direction of the main body case, and the leaf spring member stands up from both ends of the base surface and the distance between the upper ends is gradually narrowed. It is preferable to employ a configuration in which the holding body is arranged on the base surface in a state in which the outer side surface of the holding body is in contact with the rising sloped surface. . As a result, the holder can be mounted only on the base surface, and the position of the holder can be maintained in a stable posture.

Further, it is preferable that a guide mechanism is provided between the pair of holding bodies and the main body case so as to move the holding bodies along the direction in which the bifurcated branch springs are spaced apart from each other. With such a configuration, when the relative position of the holding body changes, it is possible to achieve smooth movement while reliably maintaining the mounting posture of the holding body.

Further, the holding body is provided with a spring accommodating portion extending in the front-rear direction, the spring accommodating portion being provided longer than the length in the front-rear direction of the bifurcated branch spring, and the outer end of the bifurcated branched spring. A configuration is also adopted in which a stopper wall portion that is substantially in contact with the edge is provided. By providing such a stopper wall portion, it is possible to effectively prevent the tip end side of the bifurcated branch spring from being displaced outward when the clip is pushed out.

Therefore, the clip 10 pushed through the insertion opening 116 does not drop off from the insertion opening 116.

Next, the clip mounting device 15 according to the present embodiment.
How to use is explained.

First, as described above, it is assumed that the clips 10 having the sizes corresponding to the respective passages are accommodated in the first to third passages 105 to 107, and the clip attaching device 15 as a whole is held in one hand. It is assumed that the user holds a document and holds it in the other hand. Further, it is assumed that the third passage 107 that receives the smallest clip 10 is connected to the insertion port 21. In this case, as shown in FIG.
Each of the bifurcated branch springs 2 held by the pair of left and right holders 70, 70 is in a position closest to each other so that the front and rear cams 102, 103 are vertically long.
The mutual separation widths of 3 and 23 are set at positions corresponding to the minimum clip 10.

Now, when a document is inserted into the insertion port 21 and a pressing operation surface portion 34 of the operation portion 24 of the clip attaching device 15 is pressed with a thumb, for example, a forward sliding force is applied, the nail of the operation portion 24 is pressed. The piece 40 acts so as to press the outer surface of the back portion 11 of the clip 10 located at the tip. Then, the sandwiching pieces 12, 1 of the clip 10
The base portion of the bifurcated bifurcated spring 23 enters into a slight gap formed between the two distal ends, and is further pushed forward to be deformed so as to gradually expand between the sandwiching pieces 12, 12. Then, at the moment when the clip 10 passes through the bifurcated branch spring 23, the edge of the document is sandwiched between the flared gripping pieces 12 and 12, and the elastic restoring force of the gripping pieces 12 and 12 causes the document to move. The binding force is applied to.

Here, when the size of the clip 10 to be used is changed from the minimum size to the intermediate size, the rotary knob tube 99 of the holder member 17 is pinched and rotated by a predetermined angle (approximately 120 degrees in this embodiment). . As a result, the front and rear cams 102 and 103 take an inclined posture by rotating about 120 degrees from the above position, as shown in FIG. At this time, the outer peripheral surface portion of each cam 102, 103 is
The holding body 70 is moved in the opening direction while being in contact with the inner end of the cam contact portion 80 against the spring force of the upright inclined surface 65 of the leaf spring member 63, and at the same time, the left and right of the intermediate size clip 10 is moved. The pair of left and right bifurcated bifurcated springs 23, 23 are relatively separated from each other by a separation width corresponding to the width,
By the same operation as described above, the intermediate size clip 10 can be pushed out.

When the maximum size clip 10 is pushed out, the holder member 17 may be further rotated by approximately 120 degrees. As a result, as shown in FIG. 7, the holding bodies 70, 70 are further distant from the spring force of the upright inclined surface 65, and the relative positions thereof become the farthest positions, corresponding to the clip 10 having the maximum width. The bifurcated branch spring 23 is separated from the position.

Therefore, according to the structure of this embodiment, even if the single operation section 24 is used, a clip of an arbitrary size is selected in accordance with a change in the binding width to perform a predetermined binding operation. Get the effect that you can do it.

The clip mounting device 10 according to the present invention.
Is not limited to the illustrated configuration example, as long as the clips can be extruded according to a plurality of sizes, the number of passages formed can be appropriately increased or decreased.

[0041]

As described above, according to the present invention,
An operating mechanism is provided between the holder member and the holding body, and the movement of the operating mechanism allows the relative position of the holding body to be changed for each lateral width size of the clip to adjust the mutual separation width of the bifurcated branch spring. Therefore, by adopting the leaf spring, the leaf spring can be easily assembled, and the manufacturing efficiency can be dramatically improved. Further, since the separation width of the bifurcated branch spring is adjusted by changing the relative position of the holder by the operating mechanism, the position of the bifurcated branch spring can be adjusted according to the size of the clip simply by changing the rotational position of the holder member with respect to the main body case. Can be adjusted automatically.

Further, since the actuating mechanism is constituted by the cam provided on the tip cam shaft of the holder member and the cam contact portion provided inside each of the holders, the rotation of the holder member causes the holder to rotate. Therefore, stable relative movement of the holder can be expected.

Further, since the cam is composed of two cams, and each cam comes into contact with the cam contact portion of each holder, the size of each clip is adjusted when the separation width of the bifurcated branch spring is adjusted. Accordingly, the bifurcated bifurcated spring can move relative to the predetermined center of rotation equally, and it is possible to ensure the expansion operation of the holding piece while allowing the clip to pass.

Further, the leaf spring member is constituted by a pair of upright inclined surfaces which are erected from both ends of the base surface and are oriented so that a space between upper ends thereof is gradually narrowed. Since the holding body is arranged on the base surface in a state where the side surfaces are in contact with each other, the position of the holding body can be maintained in a stable posture and the assembling work becomes easy.

Further, according to the structure provided with the guide mechanism for moving the holding body along the separating approaching direction of the bifurcated branch spring, the holding body can be smoothly moved without rattling when the relative position of the holding body is changed. Can be made.

Further, according to the constitution in which the stopper wall portion is provided in the spring accommodating portion of the holding body, it is possible to effectively prevent the tip end side of the bifurcated branched spring from being displaced outward when the clip is pushed out. You can
