Description

   The present invention relates to a sheet processing apparatus that processes sheets such as paper and cloth, and more particularly to a compact sheet processing apparatus that can process with a weak force.

Conventionally, in sheet processing apparatuses such as punches, staplers, stamps, and press machines, a base on which a sheet is placed, an arm standing on the base, and an operation member rotatably attached to the arm are provided. An operation for processing the sheet is performed at one end portion of the operation member, and a processing tool such as a punch blade, a staple needle, a stamp tool, and a press tool is pushed down toward the sheet at the other end portion, The sheet is configured to be processed.
In such a sheet processing apparatus, various techniques for enabling a sheet to be processed with a weak force have been proposed.

For example, in Patent Document 1 and Patent Document 2, when the operation member of the two-hole punch is pressed down, the timing of pressing down one punch blade and pressing the other punch blade is shifted, which is necessary for drilling. A technique for reducing the initial operating force is disclosed.
Further, in Patent Document 3, the upper cover and the base cover of the stapler are relatively rotated forward from the pivot portion of the main body housing the staple needle, thereby reducing the pressing force of the upper cover on the base cover. Technology is disclosed.

FIG. 1 is an explanatory view showing a sheet processing apparatus 1 according to an embodiment of the present invention.
This sheet processing apparatus 1 is a die cutting punch for forming a die cutting pattern of a desired shape on a sheet material such as paper, cloth, cellophane, and leather, and is erected on a base 10 on which a sheet is placed and a base. The arm 20, the operation member 30 that is rotatably attached to the arm 20, the push-down member 40 that is turnably attached to the arm 20, and the link member 50 that connects the push-down member 40 and the operation member 30. And a punch blade 60 for perforating the sheet, and a punch base 61 for perforating the sheet in cooperation with the punch blade 60. FIG. 1 shows a state in which the sheet processing apparatus is cut along the inner surface of one arm 20, and a punch blade 60 that passes through the inside of the punch base 61 is represented by a broken line.

The base 10 is a part on which the sheet is placed, and is formed integrally with the punch base 61 by a metal such as zinc. A step is provided in a portion where the punch base 61 is attached, and a sheet insertion slit 62 is formed between the base 10 and the punch base. With the sheet inserted into the slit 62, a punch blade 60 described later is lowered to push out a sheet piece perforated from the opening 11 provided at the center of the base 10. The upper edge portion of the opening 11 functions as a lower blade for punching a sheet by cooperating with the punch blade 60.
A pair of arms 20 are erected on both sides of the base 10.

The pair of arms 20 are provided with pivot portions h1 and h2 at two locations on the top and bottom, and an operating member 30 is rotatably attached to the upper pivot portion h1 and is attached to the lower pivot portion h2. A push-down member 40 is rotatably attached.
The operation member 30 mounted on the upper side is a member for performing a drilling operation by pushing down one end portion A, and each arm is provided via a pivotal support portion h1 located at a predetermined distance M2 from the other end portion B. It is pivotally attached to 20 in a swingable manner.

The push-down member 40 attached below is a member for pushing down the punch blade 60, and the punch blade 60 is rotatably supported by the punch blade support portion provided at the one end D.
The other end portion C of the pressing member 40 and the other end portion B of the operation member 30 are connected by a link member 50. The push-down member 40 is provided with a slide portion that moves up and down while slidably contacting the slide groove 21 provided in the arm 20, and allows the punch blade 60 to move up and down smoothly.

The length and attachment state of the operation member 30, the push-down member 40, and the link member 50 are such that the distance M2 between the pivot portion h1 of the operation member 30 and the other end B is different from that of the pivot portion h2 of the push-down member 40. It is designed to be smaller than the distance M3 to the end C, for example, to be a half.
The distance M1 from the one end A of the operating member 30 to the pivot h1 is set to be larger than the distance M2 from the other end according to the desired operating force, and the distance from the one end D of the push-down member 40 to the pivot h2 is set. The distance M4 is set to be smaller than the distance M3 from the other end C according to a desired pressing force.

A punch base 61 is fixed to the base 10. The punch base 61 is cast by die-casting a metal such as zinc, and a guide path through which the punch blade 60 is guided while sliding is provided. This guide path is continuous with the opening 11 provided in the base 10.
A punch blade 60 is inserted into the guide path with the blade tip facing downward. When the operation member 30 is pushed down, the push-down member 40 is rotated via the link member 50, and the punch blade 60 is moved. It descends along the guideway.
A step 62 provided in the base 10 forms a slit 62 between the punch base 61 and a sheet is inserted into the slit 62.

The usage state of the sheet processing apparatus having the above-described configuration will be described.
In the initial state shown in FIG. 1, a sheet to be punched is inserted into the slit 62.
And as shown in FIG. 2, the one end part A of the operation member 30 is pushed down. Then, the other end portion C of the push-down member 40 is lifted upward via the link member 50, and the punch blade 60 is pushed down at one end portion D as shown in FIG. 11, the sheet inserted in the slit 62 is punched.

At this time, the relationship between the operating force F1 applied to the one end A of the operating member 30 and the force F2 applied to the other end B is expressed by the formula F1 × M1 = F2 × M2.
On the other hand, when the other end B of the operating member 30 is pulled upward, an upward force F2 acts on the other end C of the push-down member via the link member 50, and the punching blade 60 is caused by the upward force F2. A predetermined pressing force F3 is applied. The force relationship in this case is represented by the formula F2 × M3 = F3 × M4.

  Accordingly, for example, the ratio of the distance M1 from the one end A of the operation member 30 to the distance M2 from the other end B is set to 6: 1, and the distance M3 from the other end B of the operation member 30 and the one end D are determined. When the ratio to the distance M4 is set to 2: 1, the operation can be performed with a force (that is, F1) that is approximately 1/12 of the pressing force (that is, F3) of the punch blade 60. As described above, since the operation can be performed with a half of the normal lever force (ie, F2), the operation force can be remarkably reduced.

In this embodiment, the processing tool is a punch blade 60 with the blade tip directed downward, and a punch is provided by providing a base having a guide path through which the punch blade 60 is guided and a slit into which a sheet is inserted. However, as long as the sheet is a processing apparatus, another sheet may be used.
For example, the processing tool is a staple needle with the needle tip facing downward, and a storage box is provided for housing the connecting body of the slapling needle, and the push-down member pushes down the single staple needle from the connecting body. You may comprise so that a needle may pierce a sheet | seat. Thus, a stapler that can be operated with a remarkably small force can be formed.

Further, the processing tool is a stamp tool provided with a marking surface at the lower end, an ink supply portion for attaching or exuding ink to the marking surface of the slump tool is provided, and the pressing member lowers the stamp tool, thereby reducing the sheet. A predetermined pattern may be displayed on the screen. Thereby, it is possible to form a stamp that can be operated with a remarkably small force.
Further, the processing tool may be a pressing tool having a pressing surface below, and the operation member lowers the pressing tool so that irregularities are formed on the surface of the sheet. Thereby, it is possible to form a press that can be operated with a remarkably small force.

In the present invention, the distance M2 between the pivot portion h1 of the operation member 30 and the other end B is different from that of the pivot portion h2 of the push-down member 40 in accordance with the positions of the pivot portions h1 and h2 provided on the arm 20. What is necessary is just to design the operation member 30, the pressing member 40, and the link member 50 suitably so that it may become smaller than the distance M3 between the edge parts C. FIG.
Further, according to the present invention, the pivoting portion, the operating member, the push-down member, and the link member are arranged in such a manner that the distance M2 between the pivoting portion h1 of the operating member 30 and the connecting portion B is the pivoting portion h2 of the pushing-down member 40. Since the distance M3 may be smaller than the distance M3 between the first and second connecting portions C, for example, a configuration such as the first modification shown in FIG. 4, the second modification shown in FIG. 5, and the third modification shown in FIG. It may be.

  Further, the arrangement of the pivotal support portion, the operation member, the push-down member, and the link member of the present invention is such that the push-down member 40 and the operation member 30 are connected, and the pivot support portion h1 of the operation member 30 and the connection portion B are connected. The distance M2 may be made smaller than the distance M3 between the pivot part h2 of the push-down member 40 and the connecting part B. Therefore, even in the fourth modification shown in FIG. An aspect like the 5th modification shown in below may be sufficient.

In any case, the relationship between the operating force F1 applied to the operating portion A of the operating member 30 and the force F2 applied to the connecting portion B is expressed by the formula F1 × M1 = F2 × M2, and the operating member 30 The force F3 that the force F2 of the connecting portion B acts on the push-down portion D of the push-down member 40 via the link member 50 is expressed by the following formula: F3 = F2 × M3 ÷ M4.
Thereby, for example, the ratio of the distance M1 from the operation portion A of the operation member 30 to the distance M2 from the connection portion B is set to 6: 1, and the distance M3 from the connection portion C (or B) of the operation member 30 is pressed down. When the ratio with the distance M4 from the part D is set to 2: 1, the operation can be performed with a force F1 that is about 1/12 of the force for pushing down the processing tool (ie, F3).

  The present invention is not limited to an office sheet processing apparatus, and can be applied to all sheet processing apparatuses that apply the lever principle to an operation member.
