Description

490367 A7 ____ B7 _; __ 5. Description of the invention (i) Background of the invention Standard staples have long been used to staple stacks of paper or other materials within a predetermined stacking thickness. Generally, the needles of the longer legs are compared. Short-leg staples are more capable of stapling thick stacks of paper, such as standard staple sizes, which are constructed for stapling 2 to 30 or 70 stacks. U.S. Patent No. 4,318,555 discloses a stapler, which can cut and form staples by self-continuously supplying the wire. The height to be stapled is sensed, and the length of the wire to be cut is selected accordingly. The bottom piece then forms a staple and is driven into the stapled paper. When different wire lengths are selected, the nail is provided with variable length legs and a fixed length crown. U.S. Patent Nos. 4,538,276 and 5,007,483 disclose staple cartridges for staplers, including straight, flat strips of staple blanks that are fed to a formed piece to bend the blanks into a single size. The moving part then drives the formed staples to an anvil, and the anvil hits the slot or the wings to bend the legs of the staples to the stack. # 烟 明 SUMMARY The present invention relates to a stapler It can feed a predetermined long staple blank, and shape the blank into a staple with a smaller large crown size, and preferably has a corresponding or smaller leg length. Therefore, by changing the staple textures made, a single source of staple blanks can be used to bind a large range of stack sizes. The paper size is suitable for the National Standard (CNS) A4 specification (^ x297). It is stapled, for example, 30 to a stack of paper.

The blade is placed in the cavity of the small molded part, the same width! The front surface 68 of the moving blade 68 moves in the longitudinal direction. The driving blades 128 and ι30 each have a driving surface 132 and 134. In the configuration of the large crown, the driving surface 134 of the large driving blade 130 For the driving surface of the operation, when it is aligned with the square staple material before the operation top curved surface of the curved plate Π0, that is, at the top surface of the large curved portion 116. Also in this configuration, 'the side portion of the operation molding is the side portion 72 of the large molding portion 70' when it is also aligned above the front staple blank 58, therefore, the operation side The sections are laterally adjacent on opposite sides of the curved surface of the operating roof. The small side portion 92 and the small curved portion i 14 are both located outside the plane passing through the operation surface and the front staple blank 58. Referring to FIG. 11, the blank-restricting grooves 98 and 100 preferably extend further beyond the diameter of the staple blank 58 in the vertical direction, and preferably exceed one-half and the full diameter of the staple blank 58 in the vertical direction. between. Generally, the cross section of the staple blank is oval, and the long axis is measured as 0 · 022 pairs and the short axis is measured as 〇 〇 18 忖. The optimal extra vertical clearance of the embryo restraint is 0 · 01 and 0. · Between 015 inches. The large curved portion 116 shown is coupled to one of the crown portions 136 of the preform 58, and the side portion of the operation is coupled to the leg portion 13 of the preform 5 8 which has not yet been curved. When the molding assembly is forced downward in relation to the bent plate 11 〇, the paper size of the operating side applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 490367 A7 B7 V. Description of the invention (10 ) The edge is to bend the leg around the side of the large curved portion U6 of the operation, and the small curved plate located outside the plane of the staple blank 58 is preferably not bent. The width of the front crown is less than or equal to the gap ι06, and greater than or equal to the width 118. The molding leg of the embryo 58 is located in the gap or gap 120. The large-shaped part 70 preferably includes an inclined surface 139 of the cam portion 14m, aligned with the inclined surface for movement along a path, so as to push and push the cam portion 143 of the bent plate 110. When the molded part assembly passes the vertical point in its stroke and the leg part of the staple blank part 58 is completed, the cam part 141 of the molded part assembly moves the bent plate 110 out of the driving path of the driving part assembly. The formed staples can be driven into the stack of paper 68. The cam portion may be located on another element that moves with the molding / drive assembly, or the bent plate may be simply moved independently, for example, using another motor or a solenoid valve or other device. Referring to Figures 13 and 14, the small driver blade includes a leg portion for coupling to the top of the coupling plate 76 during driving. As shown in Figure 8, the driver actuator 64 has a flat plunger 142, preferably fixed to the top of the small driver blade.
