Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an automatic clipping device that can automatically clip documents, etc.

Problems to be Solved by the Prior Art and Invention When clipping documents, etc., it was extremely cumbersome as it required opening each clip each time. The object of the present invention is to provide a completely new automatic clip clamping tool that does not exist in the past and solves these problems.

Measures to solve the problem: A clamping tool body with a through hole in the lower end of the opposing side walls through which only one loaded clip can pass, and a gap in the lower surface with a width that allows only the inner ring of the clip to pass through. and a lever fixed to the main body so as to be able to swing at a required angle through a spring acting in a direction away from the main body, and the inner ring portion of the clip moves integrally with the lever so that the inner ring portion of the clip is attached to the hook piece. A pressing body that is moved until it engages with the hook and then presses the rocking body, the rocking body that is moved downward by the pressing body and moved upward by a spring to rock within a required angle range, and the rocking body When the clip swings integrally with the clip and is slidably attached in the front-rear direction, as the clip swings downward, the hook at the tip of the clip pulls and flexes the engaged inner ring part of the clip, and returns to the lower end position. The hook piece is guided by a cam projection and slides relative to the rocking body to project forward and release the hook from the inner ring portion of the clip.

Embodiment An embodiment of the present invention will be described below based on the drawings.

First of all, Fig. 1 shows the overall appearance. 1 is a flat cylindrical clip made of transparent plastic with a lid 2 fitted into the upper opening, and 3 is a hollow part with an opening on the front side. It is a lever which has a shape and whose rear part of the lower end is rotatably connected to the main body 1 by a support shaft 4, so that the rear part of the main body 1 can be freely retracted into the inside from the open front side surface. , 5 bends a wire having a circular cross section into an oblong shape approximately twice around the circumference to form an outer ring portion 5a and an inner ring portion 5b, and inserts documents, etc. between the inner ring portion 5b and outer ring portion 5a. This is a structural clip. The clips 5 are not separate entities one by one, but constitute an assembly in which a required number of clips are stacked and bonded together like the needles of a stapler, and each can be easily separated by a required shearing force. Next, Figures 2 to 5 show longitudinal sections of main parts in the front-rear direction,
FIG. 6 shows longitudinal sections of main parts in the lateral direction. First, the lower surface of the main body 1 is opened, and L-shaped guide rails 6, 6' are mounted at the lower edges of both wide lateral sides. A gap 7 is formed between the guide rails 6 and 6' with a width that allows the inner ring portion 5b of the clip 5 to pass through but does not allow the outer ring portion 5a to pass through. Through holes 8 and 8' are set at a height that allows passage of only one clip at the lowest end of the clip stack placed on the guide rails 6 and 6', and the guide rails at the rear of both lateral sides are rail 6,
Side walls 9, 9' extend further downward from 6', and inclined plate-shaped stoppers 11, 1 are provided at the front upper end of the inner surface of the side walls to abut against both lateral edges of the rocking body 10, which will be described later.
1' and slightly behind it, there are protruding pins 13, 13' for hooking the upper ends of coil springs 12, 12' whose lower ends are similarly fixed to both side edges of the rocking body 10, and the side walls 9, A cam protrusion 15 whose upper surface is inclined downward toward the front is installed at the front end of a horizontal bottom plate 14 that connects the lower edge of the base plate 9'. Next, the lever 3 is rotatably connected to the side wall 9, 9' of the container body 1 by the support shaft 4 as described above at a position near the rear edge of the side wall 9, 9'. rear side 17
A leaf spring 18 is interposed between the main body 1 and the lever 3, which acts in a direction to separate them from each other.
The bottom plate 14 of the main body 1 abuts against the stoppers 19, 19' protruding from the side surfaces of the lever 3, so that the lever 3 is kept opened at a required angle in the normal state. Between the side walls 9 and 9' of the clamp main body 1, there is an approximately 4.
A semicircular pressing body 20 is provided to protrude from the rear side surface 16 of the lever 3. The width of the pressing body 20 is set to be narrower than the gap 7 between the guide rails 6, 6' described above, and a step 21 is formed on the peripheral surface, and the pressing body 20 is moved around the step 21 as a boundary. Divided into a large diameter portion 20a and a small diameter portion 20b, the support shaft 4 of the large diameter portion 20a
The radius centered at is such that its peripheral surface can pass through the through hole 8' in the rear side surface 17 of the clamp main body 1, and is slightly lower than the upper surface of the lowermost clip 5 placed on the guide rails 6, 6'. It is set to take a trajectory, and
The radius of the small-diameter portion 20b is set so that its peripheral surface follows a locus lower than the lower surface of the lowermost clip 5, and the step portion 21 is positioned so that the lever 3 is separated from the main body 1 by the leaf spring 18 to the maximum extent possible. It is set at a position where it comes into contact with the rear end surface of the clip 6 in its normal state (see FIG. 2). Below the main body 1, the side wall 9,
A rocking body 10 whose rear end is rotatably supported by a support shaft 4 in the same manner as the pressing body 20 is disposed between the two parts 9'. As described above, the rocking body 10 is pulled upward by the coil springs 12, 12', and in the normal state it hits the stoppers 11, 11' and maintains an upwardly tilted posture. A hook 23 having a hook 22 facing rearward at the front end of the rocking body 10 swings integrally with the rocking body 10, and is slidable along the rocking body 10 so that the hook can be displaced. A coil spring 26 interposed between the receiving plate 24 and the front end surface 25 of the rocking body 10 maintains the retracted state. In this normal state, the hook 22 at the tip of the hook 23 is positioned between the inner ring part 5b and the outer ring part 5a of the lowermost clip 5 placed on the guide rails 6, 6'. length is set (second
(see figure). When the rear surface 16 of the lever 3 is swung by a required angle against the leaf spring 18 from the normal state shown in FIG. The body 20 also rotates,
First, the stepped portion 21 presses the rear end surface of the lowermost clip 5 to move it forward, and the inner ring portion 5b of the clip 5 fits into and engages with the hook 22 of the hook piece 23. At this time, the shape of the pressing body 20 is designed so that the front end surface of the small diameter portion 20b of the pressing body 20 comes into contact with the upper surface of the rocking body 10 (see FIG. 3).
When the lever 3 is further pressed, the rotation of the pressing body 20 also pushes the oscillating body 10, and the coil springs 12, 12'
As the hooking piece 23 moves downward against the force, the hook 23 also reaches its lower end, so that the inner ring portion 5b that has engaged with the hook 22 is pulled downward and flexed, causing the inner ring portion 5b and the outer ring portion 5a to separate. (See Figure 4). In this state, a document to be clipped is inserted into the gap between the inner ring part 5b and the outer ring part 5a. When the constant angle swinging body 10 moves downward, the cam extractor 15 is moved so that the receiving plate 24 at the rear end of the hook piece 23 comes into contact with the inclined upper surface of the cam protrusion 15 on the bottom plate 14 of the lower edge of the clamp body 1. The position of is set (see Figure 4). Therefore, when the lever 3 is further pressed to move the rocking body 10 slightly downward from this state, the hook piece 23 is pushed by the inclined upper surface of the cam projection 15 and slides against the rocking body 10, and the coil spring 26 The hook 22 is released from the inner ring part 5a of the clip 5, and the inner ring part 5b is elastically restored and the document 2 is automatically moved between the inner ring part 5b and the outer ring part 5a of the clip 5. (See Figure 5). When the pressing force on the lever 3 is released, the state shown in FIG. 2 is restored by the restoring forces of the leaf spring 18, coil spring 26, and coil springs 12, 12'.

Note that the clips may be separated one by one.

Effects of the Invention Since the present invention has the above-mentioned configuration, when the lever is operated and the pusher presses the clip, the inner ring portion (together with the outer ring) of the clip moves forward and engages the hook of the hook. When engaged and the lever operation is continued, the swinging body moves downward against the spring, the hook piece that swings integrally with the swinging body also moves down, and the inner and outer rings of the clip are expanded from each other. After inserting the paper between the inner and outer rings, by continuing to operate the lever, the engagement between the hook and the inner ring portion is released, and the paper can be automatically held by the clip. In other words, the process of separating the inner and outer ring parts of the clip and the process of re-closing them from the opened state are automatically performed by pressing and releasing the lever, thereby allowing the clip to hold documents, etc. This makes it extremely easy to stop.

Moreover, the inner ring part is hooked on the hook piece and the inner ring part is expanded (separated) from the outer ring part.
Therefore, an existing clip in which the inner and outer ring portions are located on the same plane can be used, and there is no need to use a dedicated clip.
