FIG. 4 is an enlarged perspective view of the binding center shown in FIG. 3, and FIG. 5 is a side view of the binding center shown in FIG.

As shown in FIGS. 4 and 5, the booklet 40 includes a pair of fourth guide rails 41 and a pair of fourth guide rails 41 installed along the front and rear directions on the base 21. A moving member 42 that moves in the forward and backward direction according to the moving member 42, a driving motor 43 that generates a driving force to move the moving member 42, and power that transmits the driving force generated by the driving motor 43 to the moving member 42 It includes a pair of cutting members 45 for cutting the lower end of the iron core by the forward movement of the transmission unit 44 and the moving member 42, and a bending member 46 for bending the lower end of the cut iron core.

The pair of fourth guide rails 41 may be installed side by side along the front and rear directions at positions spaced apart from each other by a predetermined interval on the upper right side of the base 21 .

The moving member 42 is formed in a substantially hexahedral shape, and a pressing member 421 may be provided at an upper end of the moving member 42 to press and rotate the pair of cutting members 45 in opposite directions.

The power transmission unit 44 may include a shaft 443 that rotates by receiving rotational force through a connection gear 442 engaged with a drive gear 441 installed on an output shaft of the drive motor 43 at one end.

For example, the drive gear 441 and the connection gear 442 may be provided as bevel gears to transmit driving force in a right angle direction.

The shaft 443 is screwed to the movable member 42, and the movable member 42 can move forward and backward by rotation of the shaft 443.

The pair of cutting members 45 are fastened with bolts to the top of the fixing block fixedly installed on the base 21, respectively, and can rotate around the bolt. A contact member 451 contacting the pressing member 421 of the moving member 42 may be provided at an upper portion of each cutting member 45 . Surfaces of each contact member 451 facing each other may protrude. Therefore, the pair of contact members 451 move in a direction away from each other when the pressing member 421 moves forward.

So, as the rear ends of the pair of cutting members 45 rotate to move away from each other when the movable member 42 moves forward, the front ends of the pair of cutting members 45 rotate to come closer to each other and cut the lower end of the iron core. .

To this end, an inclined surface may be formed at the front end of the pair of cutting members 45 to be inclined towards the center between the pair of cutting members 45 .

In addition, a fixing member 47 may be provided at the upper portion of the front end of the pair of cutting members 45 to fix the lower end of the iron core in the inserted state.

A portion around each insertion groove 471 may be formed as an inclined surface so that the lower end of the iron core can be easily cut using the cutting member 45 .

Here, the iron core is provided with a sufficient length so that many documents can be bound at one time. Therefore, in the case of a document with a small number of sheets, when binding without cutting the lower end of the iron core, the bending area at the lower end of the iron core is unnecessarily long, resulting in deterioration in the quality of binding and the possibility of the user's hand being stabbed at the end of the iron core. A safety accident may occur.

Therefore, in this embodiment, in a state where the iron core is inserted through a hole punched in the document, the lower ends of both legs of the iron core are cut while leaving the lower end of the document at a preset length.

To this end, the cutting member 46 may be disposed lower than the pedestal 22 by the set length, for example, by about 10 mm. Therefore, even if the number of documents changes, the document can be firmly bound by cutting the iron core so that the protruding length of the document is constant and bending the remaining portion by the set length.

The bending member 46 is formed in a substantially rectangular parallelepiped shape extending in the left and right directions, and a pair of bending grooves 461 are recessed downward on the upper surfaces of both sides of the bending member 46 so as to bend the lower ends of both legs of the iron core, respectively. can be formed

A cam member 48 may be provided at a lower portion of the bending member 46 to move the bending member 46 up and down by rotating in accordance with the forward and backward movement of the moving member 42 .

For example, the cam members 48 may be provided as a pair, and may be formed in a substantially arc shape that is convex downward when viewed from the side in cross section. The cam member 48 may rotate around a rotational shaft 481 installed in the center by the forward and backward movement of the movable member 42 .

That is, when the moving member 42 moves forward, the cam member 48 rotates in the rearward direction around the rotating shaft 481 as the front end is pressed downward by the moving member 42 . So, the bending member 46 moves downward by the rearward rotational motion of the cam member 48 .

On the other hand, in the cam member 48, when the movable member 42 moves backward by a preset distance, the rear end or the central portion where the rotary shaft 481 is installed is pressed downward by the movable member 42, thereby increasing the rotational shaft 481. rotates forward and downward around Therefore, the bending member 46 is moved upward by the rotational motion of the cam member 48 in the forward direction, and the lower ends of the legs on both sides of the iron core are bent in a substantially arc shape to firmly bind the document.

As described above, according to the present invention, the length of the iron core is adjusted by cutting the lower end of the iron core according to the thickness of the document to be bound, and the length of the iron core bent on the back side of the document is kept constant to improve the quality of binding.

Next, a method of operating a perforation binding device according to a preferred embodiment of the present invention will be described.

First, when the power switch provided in the input unit 80 is turned on and power is supplied, the controller 70 initializes each device and prepares for punching and bookbinding.

Therefore, the operator places the document to be bound on the pedestal 22, and the control unit controls the driving of the fixing unit 25 to press and fix the document by lowering the fixing table 27.

Next, the control unit 70 lowers the pair of drill bits 31 provided in the drilling unit 30 to control the pair of holes to be drilled in the document.

When the drilling operation is completed, the pair of drill blades 31 ascend and return to their original positions, and the control unit 70 moves the transfer unit 60 to transfer the pedestal 22 to the left toward the binding unit 40. control the drive.

Subsequently, the iron core supply unit 50 separates one iron core accommodated therein and supplies it to the bookbinding unit 40, and both legs of the iron core are formed in a pair of through holes ( 471) into a pair of holes drilled in the document.

Then, the controller 70 controls the operation of the bookbinding unit 40 to bind the document by cutting the lower ends of both legs of the iron core and bending the lower ends of both legs.

That is, the driving motor 43 provided in the binding unit 40 is driven according to the control signal of the control unit 70 to generate driving force, and the shaft 443 receives the driving force generated from the driving motor 43 and moves in one direction. rotate

Then, the movable member 42 screwed with the shaft 443 moves forward by the rotational motion of the shaft 443 .

At this time, the pressing member 421 at the top of the moving member 42 is in contact with a pair of contact members 451 installed on the pair of cutting members 45, respectively. So, the pair of cutting members 45 are rotated so that the rear ends move away from each other and the front ends come closer to each other around the bolt fastened to the fixing block.

By the rotational operation of the cutting member 45, the lower end of the iron core is cut to leave a predetermined length at the lower part of the document.

Subsequently, the drive motor 43 rotates in the opposite direction by a predetermined angle to move the moving member 42 backward. During the backward movement of the movable member 42, the cam member 48 disposed under the movable member 42 rotates forward and upward around the rotational shaft 481 to lift the bending member 46.

Then, the bending member 46 firmly binds the document by bending the lower ends of both legs of the iron core using a pair of bending grooves 461 concavely formed on the upper surface.

Meanwhile, a screw thread is formed on an outer circumferential surface of the shaft 443 so as to move the movable member 42 forward and backward by a rotational motion.

Therefore, according to the present invention, the speed of the bookbinding operation can be adjusted by adjusting the pitch of the threads formed on the outer circumferential surface of the shaft 443 .

That is, when the thread pitch of the shaft 443 is reduced, the moving speed of the moving member 42 slows down, and the position of the moving member 42 can be precisely adjusted.

On the other hand, when the thread pitch of the shaft 443 increases, the moving speed of the moving member 42 increases, so that the bookbinding operation speed can be improved.

Therefore, according to the present invention, the working speed can be adjusted by replacing the shaft with a different pitch according to the desired working speed, or the position of the moving member can be precisely controlled.

Through the process as described above, the present invention can perforate a plurality of overlapping documents, bind the documents firmly using an iron core, and bind them.

In addition, according to the present invention, it is possible to adjust the speed of bookbinding of documents by adjusting the pitch of threads formed on the shaft, and improve workability.

In addition, according to the present invention, the lower end of the iron core is cut to adjust the length according to the thickness of the document to be bound, so that the length of the iron core bent on the back side of the document is kept constant, thereby improving the quality of binding.

Although the invention made by the present inventors has been specifically described according to the above embodiments, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention.

The present invention is applied to a perforation bookbinding device technology for perforating a plurality of overlapping documents and firmly binding the documents using an iron core.
