[0037] Further, the first to fourth cylinders (72, 64, 16, 17) may be devices for maintaining operation and stop statuses by using air or oil pressure by a control device not shown, and detail description for structures and operation is omitted since it is well known in the art.

[0038] Next, operation of the punching apparatus for the wire-binding book described above according to an embodiment of the present invention will be described.

[0039] First, to precisely hold the object for binding (100) by the clip (16) mounted to the upper portion of the unit transferring unit (6) of the binding object transferring unit (2) or to set the position for returning to an initial status after operation, in the status illustrated in FIG. 4a, when the handle (81) is rotated as shown in FIG. 4b, the screw pole (84) may be rotated and the fixing plate (73) may be moved. In this time, the first cylinder (72) fixed to the fixing plate (73), the operation axis (721) of the first cylinder (72), the supporting plate (71) fixed to the front portion of the operation axis (721) and the saddle (5) fixed to the supporting plate (71) may be moved. Additionally, the saddle (5) may be smoothly moved by the first LM guide (4).

[0040] Additionally, as shown in FIG. 4b and FIG. 5a, the position of the clip (61) mounted to the upper portion of the unit transferring unit (6) may be set on a preferred position, and then the object for binding (100) may be placed on the table (12) and may contact the first alignment plate (13) and the second alignment plate (14) with edge portions thereof for correct alignment.

[0041] Next, when the operation axis (721) moves the saddle (5), fixed to the supporting plate (71), forward by operation of the first cylinder (72), the plurality of the unit transferring units (6) mounted to the saddle (5) may move together and, as shown in FIG. 4c and FIG. 5b, contact the object for binding (100), and at the same time the plurality of the clips (61) may divide the object for binding (100) and hold the sheet units (100). In this time, the clip (61) of the unit transferring unit (6) mounted to the lowest stair layer (51a) of the saddle (6) may be inserted into a portion located at a lower portion of the object for binding (100) first and the sheet unit (100) may be held, and then each of the clips (61) of the unit transferring units (6) mounted to the next stair layer (51b) to highest stair layer (51e), which are moved and contacted one after another, may divide and hold the sheet units (100) of the object for binding (100) in order.

[0042] Accordingly, the order for dividing the object for binding (100) and holding the sheet units (100) may be continued from the clip (61) of the unit transferring unit (6) mounted to the lowest stair layer (51a) of the saddle (5) to the clip (61) of the unit transferring unit (6) mounted to the highest stair layer (51e) of the saddle (5) when the saddle (5) is moved forward by operation of the first cylinder (72) and, when the holding operation of the sheet units (100) is finished, the operation of the first cylinder (72) may be stopped and the stop status may be maintained.

[0043] Next, the shut off status may be released so that the sheet unit (100) of the object for binding (100) divided by moving the first alignment plate (13) downward toward the lower portion of the table (12) by the operation of the third cylinder (16) can be moved to the punching device (15), and then by operating the second cylinder (64) of the unit transferring unit (6) mounted to the highest stair layer (51e), the sheet unit (100) of the object for binding (100), which is divided and held as shown in FIG. 4c and FIG. 5c, may be moved toward the punching device (15) and be stopped, and then by lowering the punch pin (151) of the punching device (15) the sheet unit (100) of the object for binding (100) may be punched to punch the coupling holes (100) and the status is continuously maintained. Next, the sheet unit (100) of the object for binding (100) divided by sequentially operating the second cylinders (64) of the unit transferring unit (6) mounted from the next stair layer (51d) to the lowest stair layer (51a) may be moved toward the punching device (15) and may be stopped at the status being inserted into the lower surface of the sheet unit (100) previously processed, and then when the process of the coupling holes (110) is finished by punch of the punch pin (151), there may be the object for binding (100) consisted of all stacked sheet units (100) as shown in FIGS. 4d and 5d.

[0044] Next, in the status of FIG. 5d where all coupling holes (110) were punched in the unit object for binding (100), all second cylinders (64) of the unit transferring unit (6) mounted to each of the stair layers (51a to 5e) of the saddle (5) may be return to an original status simultaneously, and the object for binding (100) held to the each of the clips (61) may be moved to the status of FIG. 5b and then stopped. Then, to move the object for binding (100) to the wire (200) binding location which is a next process, as shown in FIG. 1, in the status holding the object for binding (100) by tongs the operation axis (721) of the first cylinder (72) may be returned. In this time, as the entire saddle (5) may be returned and the clip (61) of the unit transferring unit (100) holding the object for binding (100) may be naturally separated, and therefore when, a cycle operation returning to an original standby position such as FIG. 5a may be completed.

[0045] Accordingly, in the embodiments of the present application, even an object for binding (100) having various thicknesses may easily aligned by the first and second alignment plates (16, 17), and by moving the saddle (5) forward the object for binding (100) may be divided into sheet units (100) and held by the clips (61), then at the same time as lowering the first alignment plate (16) the sheet units (100) may be sequentially moved toward the punching device (15) by operation of the second cylinder (64) of the unit transferring unit (6) and then all of the coupling holes (110) may be punched by the punch pin (151), then after returning all of the second cylinders (64) of the unit transferring unit (6), in the stopped status, the object for binding (100) may be held by tongs for transfer (19), then to transfer the object for binding (100) to the binding location the saddle (5) may be returned by operation of the first cylinder (72) and the clip (61) holding the sheet unit (100) may be separated from the object for binding (100), then to operate movement of the object for binding (100) held by the tongs for transfer (19) the second alignment plate (14) may be rotated by operation of the fourth cylinder (17) and the shut down status may be released to provide a moving passage, and therefore an operation process for punching the coupling holes (110) of the unit object for binding (100) and coupling the wire (200) may be efficiently performed and the productivity may be improved.

[0046] Further, even if the size of the object for binding (100) is changed, the position of the clip (61) of the unit transferring unit (6) may be moved left and right by the third LM guide (91) and the object for binding (100) may be divided and easily held in a stable position, and since the embossed grooves (921) of the guide plate (92) and the embossed grooves (121) of the table (12) may be interlockedly connected to correspondingly moved, the object for binding (100) may be prevented from being fallen until it is placed on the table (12) and therefore it may provide the effect of increasing operation efficiency.

[0047] Additionally, as shown in FIG. 6, as the front portion of the resilient part (611) of the clip (61) may be smoothly open and restored by a spring (616) providing elastic force and arranged at the center, it may be freely inserted into the object for binding (100) and easily picked, and therefore the efficiency for clip operation for punch may be improved.

[0048] The forgoing disclosure explains and illustrates preferred embodiments of the present invention, but it is not intended to be limited to the configuration and operation illustrated and explained. Accordingly, as a person having ordinary skill in the art can easily understand that the embodiments can be properly changed and modified, proper modification and variations and its equivalents are within the scope of the present invention.
