Through this, the material (10) can be cut to an accurate length during the cutting process carried out in the subsequent process.

[0040] The base part (101) is for supporting the main moving frame (110), and can be configured so that the main moving frame (110) can move back and forth left and right through the first position adjustment part (111).

[0041] The main moving frame (110) can be moved linearly left and right from the base part (101) so that the position of the guide roller part (141) can be moved back and forth in the Y-axis direction, which is the left and right direction of the base part (101), according to the position and shape of the material (10). For example, the main moving frame (110) can be provided to be moved back and forth left and right from the base part (101) through the first position adjustment part (111).

[0042] Specifically, the main moving frame (110) is intended to move the position of the guide roller part (141) left and right from the base part (101), and may largely include a left-right moving body part (113) and an up-and-down moving support body part (115). In this main moving frame (110), the up-and-down moving support body part (115) is vertically fixed to the left-and-right moving body part (113), and the left-and-right moving body part (113) is coupled to the first position adjustment part (111) to move left and right above the base part (101), and the up-and-down moving frame (120) may be installed to be movable up and down on the up-and-down moving support body part (115).

[0043] The left-right moving body part (113) can be moved back and forth on the base part (101) through the operation of the first position adjustment part (111).

[0044] The vertical movement support body part (115) has a position adjustment opening (117) formed for the input of material (10) and the position adjustment of the guide roller part (141), and can be fixed upright on the upper surface of the left-right movement body part (113). This vertical movement support body part (115) may be equipped with a main plate part (115a) coupled to the base part (101) and a support plate part (115b) for supporting and fixing the main plate part (115a).

[0045] At this time, a position adjustment opening (117) is formed in a rectangular shape in the main plate portion (115a), and support plate portions (115b) can be attached to both sides of the main plate portion (115a). Through this, the operation of the weight-weight vertical movement frame (120), rotation guide frame (130), and material guide frame (140) can be stably supported.

[0046] A first position adjustment unit (111) is provided in the base unit (101) to be coupled to the left-right movement body unit (113) so as to move the main movement frame (110) left and right.

[0047] Additionally, the first position adjustment unit (111) is provided with a left-right movement operating unit (111b) in a ball screw manner, and the first driving unit (111c) can be connected to the left-right movement operating unit (111b) in a timing belt manner.

[0048] The main moving frame (110) can be moved left and right from the base part (101) by the driving of the first driving part (111c) as the left and right moving operating part (111b) is operated.

[0049] Meanwhile, the vertical movement support body part (115) can be coupled to the main plate part (115a) so that the vertical movement frame (120) can move up and down reciprocally.

[0050] In this embodiment, another vertical movement frame (120) may be provided to be reciprocally movable up and down on the main movement frame (110) through a second position adjustment part (121) so as to be movable in a direction different from the movement direction of the main movement frame (110). Accordingly, the vertical movement frame (120) may have a rotation guide opening (120a) formed through the central part, and both ends may be connected to the main plate part (115a) so as to be movable up and down. For example, the vertical movement frame (120) may be reciprocally movable in the vertical X-axis direction.

[0051] Additionally, the vertical movement frame (120) may be formed in a rectangular shape, and a rotation guide frame (130) may be rotatably mounted in the rotation guide opening (120a). At this time, the vertical movement frame (120) may be aligned with the position adjustment opening (117) so that the rotation guide opening (120a) moves inside the position adjustment opening (117). Furthermore, a second position adjustment part (121) may be connected to both ends of the vertical movement frame (120).

[0052] The second position adjustment unit (121) may be provided in the vertical movement support body (115) so as to connect both ends of the vertical movement frame (120), and may reciprocate the vertical movement frame (120) up and down. To this end, the second position adjustment unit (121) may include a second LM guide (123) and a lifting operation unit (125), and as the lifting operation unit (125) is driven, the vertical movement frame (120) may be moved up and down by the second LM guide (123).

At this time, the lifting operating portion (125) can be provided on the main plate portion (115a) so as to be connected to the upper part of the vertical movement frame (120).

[0054] For example, the lifting operation unit (125) may be provided on the main plate portion (115a) of the vertical movement support body portion (115) so as to be connected to each end of the vertical movement frame (120), thereby enabling the vertical movement frame (120) to be lifted. To this end, the lifting operation unit (125) may include a first lifting drive unit (127) provided on the main plate portion (115a) so as to be connected to one side of the vertical movement frame (120), and a second lifting drive unit (129) provided on the vertical movement support body portion (115) so as to be connected to the upper end of the other side of the vertical movement frame.

[0055] By using the first lifting drive unit (127) and the second lifting drive unit (129) of the lifting operation unit (125) as described above, a heavy vertical moving frame (120) can be moved up and down stably and accurately. At this time, the first lifting drive unit (127) and the second lifting drive unit (129) operate in different ways to lift the vertical moving frame (120).

The first lifting screw unit (127a) may have a ball nut connected to the vertical movement frame (120) and a ball screw connected to the lifting motor unit (127b). At this time, the lifting motor unit (127b) may be connected to the upper part of the main plate unit (115a).

[0057] The first lifting drive unit (127) can move the vertical movement frame (120) simultaneously by driving together with the second lifting drive unit (129).

[0058] The second lifting drive unit (129) may be provided with a guide wheel unit (129a) rotatably provided on the upper end of the main plate unit (115a), a lifting wire unit (129b) having one end connected to the upper end of the vertical movement frame (120) so as to pass through the guide wheel unit (129a), and a cylinder unit (129c) provided on the main plate unit (115a) so as to be connected to the other end of the lifting wire unit (129b). At this time, the guide wheel unit (129a) and the lifting wire unit (129b) may be provided in a chain manner, and the lifting wire unit (129b) may be connected to the cylinder rod of the cylinder unit (129c).

[0059] As the vertical movement frame (120) moves up and down by the first lifting drive unit (127) and the second lifting drive unit (129) as described above, the position of the guide roller unit (141) can be moved up and down.

[0060] Meanwhile, a rotation guide frame (130) may be rotatably provided in the rotation guide opening (120a) of the vertical movement frame (120).

[0061] The rotary guide frame (130) is rotatably mounted in the rotary guide opening (120a) and can be rotated around the rotary guide opening (120a) by the third position adjustment part (131). Through such a rotary guide frame (130), the guide roller part (141) can be rotated around the Z-axis. Through this, the guide roller part (141) can be reciprocated in the X-axis and Y-axis directions and rotated around the Z-axis. That is, the guide roller part (141) can be easily moved in the three axes (X-axis, Y-axis, Z-axis).

[0062] Additionally, the rotation guide frame (130) is formed in a ring shape, with a material guide frame (140) coupled inside, and its outer surface can be rotatably mounted in the rotation guide opening (120a).

[0065] In addition, a material guide frame (140) can be combined inside the rotation guide frame (130).

[0066] The material guide frame (140) is provided on the rotary guide frame (130) and can support and guide the material (10). For example, the material guide frame (140) may include a guide roller section (141) for supporting and guiding the material (10), a roller fixing support section (143) and a roller moving support section (145) for installing the guide roller section (141), and a material support operating section (147) for fixing the material (10) using the guide roller section (141).

[0067] When the material (10) is fed between the guide rollers (141) of this material guide frame (140), the guide rollers (141) move by the material support operating part (147) to support the material (10).

[0068] The guide roller section (141) may include a fixed roller section (141a) coupled to a roller fixed support section (143) and a movable roller section (141b) coupled to a roller moving support section (145).

The lifting bracket (149a) can be guided to lift accurately and stably by a guide rod (149d). The upper end of the guide rod (149d) is fixed to the lifting bracket (149a), and the lower end can be inserted into the fixed block member (149a) to allow for lifting.

[0071] At this time, the space between the lifting bracket (149b) and the elastic support (149c) can be provided by a coil spring.

[0074] For example, the roller fixing support member (143) may include a first support member (143a) which is fixed to the rotary guide frame (130) to be coupled with a fixed roller member (141a), and a second support member (143b) which is fixed to the rotary guide frame (130) to correspond to the first support member (143a) and to which a material support operating member (147) is coupled. At this time, a movable roller member (141b) may be coupled between the first support member (143a) and the second support member (143b) so as to be movable up and down. The first support member (143a) may be coupled to be located on the inner surface of the lower part of the rotary guide frame (130), and the second support member (143b) may be coupled to be located on the inner surface of the upper part of the rotary guide frame (130).

[0075] The roller movement support member (145) may be coupled with a movable roller member (141b) and may be movably coupled to a material support operating member (147). For example, the roller movement support member (145) may be provided with a plurality of movable roller members (141b) spaced apart in a row.

[0076] The material support operating part (147) may include a plurality of guide rod members (147a) provided in the roller fixing support part (143) to pass through the roller moving support part (145), and an actuator (147b) provided in the roller fixing support part (143) to be connected to the roller moving support part (145) and to move the roller moving support part (145).
