[0064] A hook 550 is installed at the rear of the housing 510 to hook the chain 720. [ That is, the stopper 550 is rotatably coupled to a portion of the housing 510 through a hinge shaft so that its rear end is rotatably movable up and down, and at its rear end is provided a chain 720 of the chain drive means 700 The hooks 552 are formed. A slider cylinder 560 is provided between the housing 510 and the slider 550 to actuate the slider 550. In other words, the latching cylinder 560 is provided with a latching rod 562 for selectively expanding and contracting, and one end of the latching cylinder 560 is hinged to the housing connecting port 564 protruded upward from the upper surface of the housing 510 And the end of the latching rod 562 is hingedly coupled to the latching coupling 566 protruding upward from the upper surface of the latching plate 550 to be rotatable. When the latching rod 562 is extended, the latching rod 550 is pushed to lower the rear end of the latching rod 550 so that the hooking hook 552 is caught by the chain 720. When the latching rod 562 is retracted, The rear end of the latch 550 descends from the chain 720 while rising.

Here, the conveying unit 600 is a table on which a plurality of base materials M are placed when the carriage 500 moves while pulling the plurality of base materials M, and the conveying unit 600 has a length sufficient for the length of the base material M to be pulled, And is long enough to have a length.

The chain drive means 700 for transferring the carriage 500 along the transfer unit 600 includes a pair of chain sprockets 720 rotatably mounted on the front and rear sides of the transfer unit 600, And at least one of the pair of chain sprockets 720 is connected to a driving motor (not shown) to transmit the driving force.

Now, the operating relationship of the composite ejector system according to the present invention thus configured will be described.

When the base material (M) is pulled out through the composite drawer system according to the present invention, a plurality of base materials (M) can be operated at a time.

That is, the front ends of the plurality of base materials M are linearly pulled by a separate device so that a plurality of base materials M can be inserted into the drawing holes 410 of the die 400. Then, a plurality of preformed base materials (M) are wound around the bobbin machine (100). At this time, the bobbin machine 100 adjusts the entire diameter of the bobbin cylinder member 170 according to the size of the base material M as shown in FIGS. 2 and 5. When the plurality of base materials M are installed on the bobbin cylinder member 170, the spaces are wound around the plurality of bifurcated ring members 180 so that they are installed without being interfered with each other.

Then, the plurality of base materials (M) are unwound and supplied to the snapper (200). Then, the plurality of base materials (M) are straightened in the snap device (200) and guided to the drawing hole (410) of the die (400). That is, when the base material M is supplied, the first pressure plate 270 first descends and cooperates with the first base plate 212 to catch the base material M first. In this state, the bobbin case 100 is snapped So that the base material M supplied from the bobbin machine 100 is straightened. The first pressure plate 270 is lifted to release the holding state of the base material M and the second pressure plate 280 is lowered while descending the cleaner The cloth 290 is brought into close contact with the upper and lower surfaces of the base material M to remove the foreign substances adhering to the surface of the base material M. [

The snapper 200 adjusts the vertical position of the upper horizontal roller 240 so that the plurality of base materials M are guided along the predetermined path to the drawing hole 410 of the die 400, And the space formed between the lower horizontal roller 230, the upper horizontal roller 240, and the interval adjusting vertical roller 250 is constantly regulated by adjusting the left and right positions of the upper and lower horizontal rollers 250 and 250. Then, the mother material M is guided to the corresponding space in the partitioned space, and stably guided to the drawing hole 410 of the die 400 in a state in which the movement is minimized without colliding with each other.

Next, a plurality of base materials M having passed through the drawing hole 410 of the die 400 are gripped by the carriage 500 and pulled out to start drawing. When drawing is started, The work is temporarily stopped and a part of the front end of the plurality of base materials M is cut by the shaker 300 to remove the line work. This is because the wire-worked portion of the base material M is not uniform and can be cut off when pulled out, so that the pull-out operation of the base material M is started after the base material M is removed.

At this time, when cutting a part of the front ends of the plurality of base materials M having passed through the drawing hole 410 of the die 400 with the shirring machine 300, the lower base 330 is raised to support the base material M The upper cutter 370 descends to cut the base material M. [

Next, a plurality of base materials M cut back into the carriage 500 are held, and the base material M is pulled continuously along the transfer unit 600 through the chain driving means 700. At this time, the carriage 500 is operated by the carriage cylinder 520, so that the latching cylinder 560 is operated in a state where the upper and lower clamps 530 and 540 grip the plurality of mother materials M, When the chain 720 is driven to rotate by driving the drive motor (not shown) after the rear end of the chain 550 is lowered so that the hook 552 of the chain 550 is hooked on the chain 720, ).

After the drawing of the base material M is completed, the workpiece M is cut to a predetermined length through a separate cutter (not shown) and then transported to complete the entire work.
