As shown in FIGS. 1 to 11, when the twin spring 12 is supplied to the twin spring cutting mechanism 70 and the twin spring transfer mechanism 80, the power switch of the machine is closed to supply power. After the intermediate portion of the twin spring 12 is cut by the spring cutting mechanism 70, it is transferred between the lower lifting jig 100 and the upper fixing jig 90 by the twin spring transfer mechanism 80.

That is, while unfolding the twin spring (12) wound in a roll shape in a straight line, the end is inserted into a portion having a mushroom head cross section formed in the spring guide 72 constituting the twin spring cutting mechanism (70) and then long When pushed so that the end portion is caught by the transfer gear 83c constituting the twin spring transfer mechanism 80, and then the power is supplied, the controller 500 drives the cutting cylinder 79 to extend and the When the seating cylinder 79 is extended, the middle portion of the twin spring 12 is cut by the cutting arm 78.

Thereafter, the first and second transfer motors 83a and 84a are rotated in the same direction and in the same direction, thereby driving the first and second driving pulleys 83b and 84b, respectively. The pulley 83b and the second driving pulley 84b transmit power to the transfer gear 83c and the timing pulleys 84c and 84d through the belt 83d and the transfer belt 84e, respectively.

At this time, the twin spring 12 engaged with the transfer gear 83c is transferred and the end of the twin spring 12 is engaged with the transfer belt 84e by both the transfer gear 83c and the transfer belt 84e. Are transported at the same time.

That is, since the first feed motor 83a and the second feed motor 84a are rotated in the same direction with the same feed amount, the twin spring 12 is transferred from the feed gear 83c to the feed belt 84e. While being transported by all the transport jig is located between the lower lifting jig 100 and the upper fixing jig (90).

On the other hand, the twin spring 12 is transferred not only by the transfer belt 84e but also by the transfer gear 83c, which transfers the function of the stopper that determines the stop position after insertion of the twin spring at the initial operation. Because it is configured to perform

While placing the binding object 10 such as a notebook or a calendar to be bound in the above state on the top plate 26, while close to the side alignment plate 50 installed on the side of the top plate 26 and at the same time When in close contact with the front alignment plate 52, the side and the front portion of the binding object 10 is placed in an aligned state.

At this time, when the operator applies a stepping force to the foot switch (not shown) placed on the floor, a signal is transmitted to the controller 500 while the contact point inside the foot switch is switched, and the controller 500 drives the clamp mechanism 60. To be pressed onto the upper plate 26 of the bookbinding object 10 placed on the upper plate 26.

That is, when the piston rod of the clamp cylinder 66 constituting the clamp mechanism 60 is lowered, the plate-shaped jaw 65 connected to the lower end thereof is directed toward the upper plate 26 from the binding object 10. Pressurized.

In this process, the plate-shaped jaw 65 has only linear movement in the vertical direction by the slide shafts 64a and 64b which are guided in the vertical direction by the guide bushes 63a and 63b installed on the cross plate 62b. The force line pressurizing the bookbinding object 10 is transferred to the lower transfer plate 22 through the cross plates 62a and 62b and the struts 61a and 61b, and then the upper plate 26 through the support 40. Since it is transmitted to the), the plate-shaped jaw 65 is able to press the binding object 10 more firmly.

Thereafter, the controller 500 lowers the front alignment plate 52 by the lifting movement mechanism 300 while the bookbinding object 10 is fixed to the upper plate 26 by the clamp mechanism 60 to bind the bookbinding object 10. The front part of the) is to open the passage to be directed to the binding position between the upper fixing jig 90 and the lower lifting jig 100.

That is, when the piston rod of the alignment plate lifting cylinder 304 constituting the lifting movement mechanism 100 descends while flowing into the cylinder tube, the front alignment plate 52 connected to the upper end thereof is lowered downward and bound. Open the passage through which the object 10 can pass.

At this time, the front alignment plate 52 is a straight line in the vertical direction by the elevating rods 308 and 309 guided by the guide bushes 306 and 307 installed on the support frame 302 installed in the main body 20. Only exercise is possible.

When the front alignment plate 52 is lowered as described above, the controller 500 immediately drives the front and rear forward cylinder 24 to move the piston rod forward, and at this time, the piston rod of the front and rear forward cylinder 24 The lower transfer plate 22 connected to the tip is moved forward while receiving the linear guide of the front and rear guide mechanism 30 so that the front hole 10a of the bookbinding object 10 placed on the upper plate 26 is the upper fixing jig. It stops between the open mouth of the twin spring 12 located between the 90 and the lower lifting jig (100).

At this time, the controller 500 pulls the rocking arm 128 forward by introducing the piston rod of the spring fastening cylinder 110 into the inner side of the cylinder tube, and at the same time, the arm shaft 126 connected to the rocking arm 128. The pivoting ends of the driving arms 160 and 162 connected to the arm shaft 126 are pivoted upward while being supported by the bearings 122 and 124 at both ends.

In this process, the lifting bar 102, which was clevis-coupled to the turning end of the electric arms 160 and 162, is raised through the turnbuckles 164 and 166, and the lower lifting jig 100 and the upper fixing jig 90 are raised. The twin spring 12 is placed between the adjusting bar 104 and the adjusting plate 92 between the two, and the twin spring 12 is deformed into a circular ring shape in the "C" shape of the binding object 10 It is coupled to the hole 10a.

At this time, the controller 500 causes the plate-shaped jaw 65 to be instantaneously raised by the clamp cylinder 66 of the clamp mechanism 60 holding the bookbinding object 10 on the upper plate 26 so that the inaccurate hole 10a may be removed. The center is controlled to be aligned by the twin spring 12.

At the time when the deformation of the twin spring 12 is completed as described above, the lower pivot end of the rocking arm 128 is caught by the stopper block 172 for limiting the rising position constituting the stopper mechanism 170, and at the same time, the lower portion is stopped. Movement of the lifting jig 100 is also stopped such that there is no further deformation of the twin spring 12.

The controller 500 then moves the lower lifting jig 100 in the reverse order as opposed to when the twin spring 12 is deformed to free the twin spring 12 from the lower lifting jig 100 and the upper fixing jig 90. In this operation, the piston rod of the spring fastening cylinder 110 protrudes from the cylinder tube and pushes the rocking arm 128 to the rear side, and at the same time, the arm shaft that is connected to the rocking arm 128 ( 126 is rotated by a predetermined angle while being supported by bearings 122 and 124 at both ends to pivot the pivoting end of the driving arms 160 and 162 connected to the arm shaft 126 downward.

In this process, the lifting bar 102, which was clevis-coupled to the turning end of the electric arms 160 and 162, is turned down through the turnbuckles 164 and 166, and the lower lifting jig 100 and the upper fixing jig 90 are There is a gap between.

When the lower lifting jig 100 is lowered as described above, the lower pivot end of the rocking arm 128 is stopped by the stopper block 171 for limiting the lowered position that constitutes the stopper mechanism 170, and at the same time, the lower lifting jig The descent of the 100 is also stopped so that it can no longer go down.

Further, the positions of the lower position limiting stopper block 172 and the lower position limiting stopper block 171 are adjusted by the lowering position adjusting handle 177 and the rising position adjusting handle 179 provided in the stopper mechanism 170. As a result, the lifting height of the lower lifting jig 100 can be arbitrarily adjusted, which is very easy when using twin springs 12 having different dimensions.

That is, when the lowering position adjusting handle 177 or the rising position adjusting handle 179 is turned, the lowering position adjusting screw 176 and the rising position adjusting screw 178, which are respectively connected thereto, rotate and move in the axial direction. The distance between the rocking arm 128 of the falling position limiting stopper block 171 and the rising position limiting stopper block 172 connected to the tip is adjusted.

At this time, the lower position limiting stopper block 171 is formed in the form of a block, and the bottom surface thereof is in close contact with the fixed plate 176 and is prevented from rotating as the lowered position adjusting screw 176 is rotated.

On the other hand, when the twin spring 12 is coupled to the hole 10a of the bookbinding object 10 to produce a bookbinding product, the back and forth forward cylinder 24 is reversed again to move the lower transfer plate 22 to the same position as the first time. By returning, the bookbinding finished product is removed from the lower lifting jig 100 and the upper fixing jig 90, and then the bookbinding finished product placed on the upper plate 26 is discharged by driving the discharge mechanism 130.

That is, the operation of the discharge mechanism 130 is first, when the lifting plate 138 is raised on the left and right transfer block 136 by the lifting cylinder 139, the locking pin 138a which is installed on the lifting plate 138 Ascending under the long groove 134 formed in the side alignment plate 50 protrudes upward.

Thereafter, when the belt 147b rotates while the control motor 147a constituting the belt driving mechanism 147 rotates forward, the left and right transfer block 136 connected to the middle of the belt 147b is left and right guide mechanism ( The lifting plate 138 and the locking pin 138a are simultaneously transferred to the right side while being transported to the right side while receiving the straight guide of the 140. At this time, the left end of the bookbinding finished product is caught by the locking pin 138a protruding upward. While pushing to the right, it is separated from the top plate 26.

At this time, since the locking pin 138a moves along the long hole 132 formed in the upper plate 26, the locking pin 138a does not cause interference with the upper plate 26.

Then, after the locking pin 138a provided on the elevating plate 138 is lowered by the elevating cylinder 139 again, the control motor 147a constituting the belt driving mechanism 147 is rotated in reverse. Positioned on the side alignment plate 50 is located just below the left slotted groove 134 to stand by.

As described above, the discharge of the bookbinding finished product by the control motor 147a can arbitrarily adjust the reciprocating distance and the origin according to the size of the bookbinding finished product.

As described above, the present invention is configured to automatically discharge the bookbinding finished product when the bookbinding is completed, so that the operator can immediately perform a task of preparing and loading a new bookbinding object while the bookbinding finished product is automatically discharged. It is possible to greatly improve the productivity of the work, and when the size of the twin spring is changed, it can be used by simply adjusting the position without replacing the jig, which greatly reduces the setting and preparation time of the machine. have.
