First, the raw material f-1 provided in the form of a roll as described above is mounted on the roll axis 12 of the material feeder 1, and then the pulled end is pulled to pull the first guide roll 133 and the first guide table The paper is passed through the feeding section 13 after passing through the paper feeder 131 and then passed through the second guide roll 222 and the paper feed roll 221 of the paper feed section 22 of the outer cutter 2.

The raw material f-1 fed and fed to the feeding unit 22 by the feeding unit 13 is fed to the feeding roller 22 by the feed roll 221, This is because the first sensing sensor 24 provided at a lower portion of one side of the cutter main body 21 of the outer cutter 2 continuously senses and when the proper amount is excessive or insufficient, The feed speed and feed tension of the raw material f-1 when fed to the paper feed unit 22 can be appropriately maintained.

The raw material f-1 is driven by the feeding unit 13 of the raw material feeder 1 and the feeding unit 22 of the external cutter unit 2 feeds the raw material f- It is possible to continuously supply the material to the cutter 5 in the direction of the process leading to the cutter 2, the material folding machine 3 and the material cutter 5, thereby manufacturing the L holder h through the processing of the raw material f- The process proceeds.

Specifically, the raw material f-1 fed from the feeding portion 13 of the raw material feeder 1 and fed through the feeding portion 22 along the process advancing direction (raw material feeding step S100) The workpiece is processed into a workpiece f-2 in the form of an exploded view to be manufactured by the pressing of the cutter head 23 provided on the upper side of the outer cutter 2 by the pressing operation of the cutter head 23 The cutter base 231 provided at the lower side of the cutter head 23 descends simultaneously with the lowering of the cutter base 231 and the finish sheet 232 attached to the lower side of the cutter base 231 moves the cutter base 231 The first cutter 231-1 and the bent piece 231-2 of the cutter base 231 protruding outward are formed in a state in which the thickness is reduced (contracted) by the contact pressure in the process of pressing the cutter base 231 And the fold line is bent at the center of the object material f-2 thus cut.

In this case, the raw material f-1 fed along the traveling direction is marked on a predetermined range, and this marking is applied to a second detection sensor (not shown) provided on the cutter main body 21 of the outer cutter 2 25, the feeding unit 22 is automatically driven so that the feeding of the raw material f-1 is stopped intermittently, thereby enabling the material processing in each step.

Subsequently, the target material f-2 is cut into the inside of the raw material f-1 in accordance with the primary processing by the external cutter 2 and the residual material f-3 is formed around the raw material f-1 3, the residual material f-3 is transferred in a state in which the target material f-2 formed on the inner side of the residual material f-3 is prevented from being separated, Along the process direction.

Then, the raw material f-1 having passed through the outer cutter 2 is fed to the material folding machine 3 along the process advancing direction and then folded in half. As shown in FIG. 9A, The pressing head 32 provided on the upper frame panel 312 on the upper side of the folding basic body 31 of the material folding machine 3 is lowered and brought into close contact with the third guide table 311 to prevent the flow, The lifting body 33 provided on the upper frame panel 312 is lowered and the pressing roll 331 of the lifting body 33 is brought into close contact with the rotating body 34, Both sides of the workpiece f-2 are moved in the same direction by rotating the rotary rollers 341 of the rotating body 34 in a state in which both side edges of the workpiece f-2 are pressed, , The bending head 333 of the ascending / descending member 33 descends further downward and the folding line of the workpiece f-2 is moved downward as shown in Fig. Folded in half by being pressed downward, and then dropped down along with the rotation of the rotary rollers 341, and then transferred to the ultrasonic welder 4 (S300).

Accordingly, the workpiece f-2 that has fallen in the half folded state is individually fed to the next process path by the feeder 42 of the ultrasonic bonding machine 4, 11A, the lifting plate 43 disposed below the fourth guide table 411 is lifted by the detection sensor, and the lifting plate 43 is lifted up, And the movement of the workpiece f-2 may be stopped by the transfer restricting rod 431 protruding from the upper end of the lifting plate 43.

Thereafter, as shown in FIG. 11B, the position correcting plate 44 pushes the workpiece material f-2 to one side so that one end of the workpiece material f-2 comes into close contact with the support member 412 As shown in FIG.

Next, as shown in Fig. 11C, in a state in which the squeezing plate 45 is lowered so as to come into close contact with the fourth guide table 411 to prevent the flow of the workpiece f-2, The lower end of the object material f-2 folded in half as the ultrasonic head 46 descends so as to come into close contact with the fourth guide table 411 is subjected to ultrasonic bonding, The ultrasonic bonding step S400 is completed by forming the L holder h having a structure as shown in Fig. 1 in which the folded portion and the lower end portion are clogged.

Finally, the remaining material f-3, which is the remaining part of the material from which the workpiece material f-2 has been separated by the workpiece folding machine 3, is continuously conveyed along the advancing process direction, The material is cut to an arbitrary length by the intermittent lifting operation of the second cutter 52 of the material cutter 5, thereby facilitating the recovery for the disposal process (step S 500).

In addition, the article is collected by a separate conveying device used to convey various articles to other positions, such as a conveying conveyor, and finally the articles can be finally recovered by being transported in the predetermined direction (Product recovery step: S600).

In summary, according to the apparatus (A) for manufacturing an L holder and the method (B) for manufacturing an L holder using the same according to the present invention, a raw material is processed into a single sheet through a separate process, The process for manufacturing the L holder can be carried out directly and one-stop using a single system (apparatus), so that it is possible to perform the manufacturing process of the L holder (h) more quickly and accurately.
