DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a method of and an apparatus for fastening an end of a sheet member with a clip.
2. Description of the Prior Art
Conventionally, a clipping machine is known for fastening an end of a sheet member with a clip (see Japanese Utility Model Application Laid-Open Publication No. Sho 47-12089).
The conventional clipping machine comprises, as shown in FIGS. 63 and 64, a base 1, a handle 2 attached pivotably to an end of the base 1, and a cover 3 disposed between the base 1 and the handle 2. A guiding groove 4 is formed in the upper surface of the base 1, and a row of connected clipping members 5 are contained between the guiding groove 4 and the cover 3. The connected clipping members 5 consist of clipping members 5N which are connected to each other with an adhesive agent like a sheet of staples. Each clipping member 5N is bent into a U-shape.
An end (rear end) of the connected clipping members 5 is in contact with a metallic member 7 which is slidably attached to a pressing rod 6 shown in FIG. 65. The connected clipping members 5 are pressed leftward (in FIG. 64) by the force of a spring 9 via the metallic member 7. The force enables the other end (front end) of the connected clipping members 5 to come into contact with an end 4a of the groove 4.
A pressing plate 8 is attached to the underside of the handle 2. When the handle 2 is pivoted from the position shown by the solid line to that shown by the chain line in FIG. 63, the pressing plate 8 comes into contact with the bent base part of the clipping member 5N occupying the front row of the connected clipping members 5, so that the clipping member 5N is separated from the connected clipping members 5. Then, only the separated clipping member 5N is further pressed and deformed by the pressing plate 8, and thereby an end of a plurality of sheets of paper inserted in the direction of arrow P is clipped by the clipping member 5N.
In order to perform a precise clipping operation by means of the clipping member 5N, the width of the clipping member 5N is required to be made larger. However, as a result of enlarging the clipping member 5N, the number of the clipping members 5N which can be contained in the apparatus is reduced. Therefore, disadvantageously, the apparatus must be frequently replenished with connected clipping members 5, and thus more labor is required.
SUMMARY OF THE INVENTION
In view of the aforementioned disadvantage, the present invention was made. It is therefore an object of the present invention to provide a method of and an apparatus for clipping a sheet member, in which the number of clipping members to be contained can be increased even though the width of a clipping member is larger.
In order to achieve the object, a sheet member clipping method according to an aspect of the present invention comprises the steps of keeping a plurality of platelike clipping members in a containing chamber, thereafter picking out one of the clipping members contained in the containing chamber, and bending the picked-out clipping member and clipping an end of a sheet member.
A clipping apparatus according to an aspect of the present invention comprises a containing chamber containing a plurality of substantially flat clipping members arranged in a pile, a delivery means for picking out of the containing chamber one of the clipping members contained in the containing chamber and delivering the clipping member to a clipping position where a clipping operation is performed, and a clamping means for bending the clipping member delivered to the clipping position and clipping an end of a sheet member inserted in the clipping position.
According to another aspect of the present invention, in a clipping apparatus in which a substantially flat clipping member is picked out of a containing chamber containing a plurality of clipping members arranged in a pile by a delivering means and is delivered to a clipping position where a clipping operation is performed, the clipping member delivered t
