Fig. 1 is a view showing a sewing device according to an embodiment of the present invention, and the configuration and effects of the sewing device according to the present invention will be described below with reference to fig. 1.
The general sewing machine has a sewing machine body, and a table is installed at a lower portion of the sewing machine body. At this time, a needle plate is provided on the table. In correspondence to the needle plate, a needle portion having a needle is mounted on the sewing machine body, and a presser foot for supporting a material to be sewn or the like is mounted on a side surface thereof. A hole portion through which a needle passes is formed in the needle plate, and the tooth portion is exposed at an edge to transfer a material to be sewn or the like. Further, a driving device for driving the shuttle box and the tooth portion is mounted on the lower portion of the table.
Like a general sewing device, the sewing device according to the present invention includes a sewing machine body 10 and a table 20, and the table 20 is coupled to a lower portion of the sewing machine body 10. The sewing machine body 10 is formed to extend in a length direction, and includes a head part 11 and a body part, an end of which is connected with the table 20. In addition, the sewing machine body 10 is provided with a needle portion 30 and a guide portion 300, and the table 20 is provided with a hole portion 40 through which the needle portion 30 passes, a cutting portion 100, and a groove portion 200 recessed in a vertical direction.
The needle portion 30 is located at the head portion 11 of the sewing machine body 10, and the hole portion 40 is formed at the table 20. Accordingly, the needle part 30 passes through the hole part 40 while reciprocating in the vertical direction, and the user can sew the material by moving the material to a desired direction.
Fig. 2 shows the cutting unit 100 of the sewing device according to the embodiment of the present invention in detail, and the structure and effect of the cutting unit 100 of the present invention will be described below with reference to fig. 2. The cutting part 100 includes a motor part 110, a rotation shaft 120, and a blade part 130.
The motor part 110 provides power that the rotation shaft 120 and the blade part 130 can rotate. The rotating shaft 120 is formed to extend in a longitudinal direction, and one end portion thereof is connected to the motor portion 110 and rotated by the motor portion 110. The blade part 130 is located at the other end of the rotation shaft 120, and is perpendicularly coupled to the rotation shaft 120. Accordingly, the blade part 130 serves to cut the lower cloth 2 contacting the blade part 130 among the multi-stage cloths sewn by the needle part 30 while rotating.
At this time, the rotary shaft 120 can be rotated by the electromotive force of the motor unit 110, for example, and the rotary shaft 120 can be rotated by the rotational force of the timing belt, for example.
In addition, as another example, the motor part 110 is engaged with a frame, not shown, and the frame can be moved in a vertical direction by hydraulic pressure, so that it can be lowered to prevent accidents when the blade part 130 is not used.
At this time, the blade 130 preferably rotates in the width direction. Specifically, the blade portion 130 is perpendicularly engaged with the rotating shaft 120 formed to extend in the length direction, and for the finishing process of the material for the car seat, an elongated linear sewing machine is required, and therefore, the material moves in the width direction without a moving distance restriction, and the blade portion 130 also rotates in the same direction as the width direction in which the material moves. Therefore, it is possible to cut in the same shape at a predetermined interval from the sewn portion.
The cutting part of the existing sewing device reciprocates in a vertical direction or cuts the material by rotating according to the up-and-down movement. Therefore, there is a problem: in the case of cutting multiple-stage billets, only all the multiple-stage billets can be cut, and thus when the processed billets are turned over for materialization and used, improper ending processing such as disordered ending is observed.
In contrast, the cutting part 100 of the sewing device according to the present invention is characterized in that the blade part 130 rotating in the width direction is provided, so that not all the multistage materials are cut, but only the lower material 2 is separated and cut. That is, the blade 130 is rotated in the same direction as the direction in which the material moves (not in a perpendicular direction), the position of the blade 130 itself is fixed, and the user can select the height of the material in the vertical direction and the number of the materials in contact with the blade 130, thereby adjusting the cutting height of the material.
Fig. 3 is a view showing the cutting part 100, the groove part 200 and the guide part 300 of the sewing device according to the embodiment of the present invention in detail. Fig. 4 is a side view showing a sewing device according to an embodiment of the present invention. The structure and effects of the cut part 100, the groove part 200, and the guide part 300 will be described below with reference to fig. 3 and 4.
The groove 200 is located on one side of the hole 40, and the hole 40 is located on the table 20. Although the groove portion 200 is shown inside the hole portion 40 in fig. 3, it is not limited thereto. The groove portion 200 has a shape in which the table 20 is depressed in a vertical direction, and the cutting portion 100 is located at the groove portion 200 as described later.
Specifically, according to an embodiment of the present invention, the blade portion 130 of the cutting portion 100 and a portion of the rotating shaft 120 coupled to the blade portion 130 are located inside the groove portion 200 and exposed to the outside, and the motor portion 110 and a portion of the rotating shaft 120 connected to the motor portion 110 are shielded from the top by the table 20 and are not exposed to the outside. However, the present invention is not limited to the above configuration, and according to various embodiments, the motor part 110 may be located inside the groove part 200, and the motor part 110 may be exposed to the outside.
At this time, the blade portion 130 is characterized by partially protruding a length d in a vertical direction with reference to the upper surface of the table 20. Specifically, although the blade portions 130 are positioned inside the groove portions 200, a portion of the upper side of the blade portions 130 protrudes from the upper surface of the table 20. Therefore, the material on the surface of the table 20 can be easily cut by the partially protruded blade portions 130.
With the blade portion 130 according to another embodiment of the present invention, a height d protruding in a vertical direction with reference to an upper surface of the table 20 may be adjusted. In this case, a pair of height adjusting devices is provided on both sides of the bottom surface of the motor part 110. Specifically, a pair of height adjusting devices are provided on both side surfaces of the motor part 110 so as to face each other. The height adjusting device includes: a first regulating part which is arranged on one side surface and repeatedly protrudes and dents in an up-down inclined mode; and a second regulating part formed on the other side surface in a manner corresponding to the first regulating part. Thus, the height of the electric motor part can be adjusted according to the path between the first adjusting part and the second adjusting part. Therefore, when the height is adjusted to be high by the height adjusting means, the heights of the rotating shaft 120 connected with the motor part 110 and the blade parts 130 coupled to the rotating shaft 120 are also increased. Accordingly, the height d of the blade 130 protruding in the vertical direction is increased based on the surface of the table 20, and the height of the material that can be cut by the blade 130 is also increased.
Accordingly, the user can adjust the height of the blade portion 130 by the height adjusting means in consideration of the height or the number of the billets to be cut.
The guide part 300 is
Word-shaped and includes a shielding portion 320 and a supporting portion 310. The shielding part 320 is formed to extend along the width direction, is positioned at the upper part of the cut lower material 2 and is except for the cutThe lower part of the material 1 except the cut lower material. The support part 310 is formed to extend perpendicularly from one end of the shielding part 320, and the upper part is engaged with the sewing machine body 10. In fig. 3 and 4, the support 310 is shown to be engaged with the head 11 of the sewing machine body 10, but is not limited thereto, and the position where the support 310 is engaged is the sewing machine body 10, not limited to the head 11 of the sewing machine body 10.
In this case, the other end of the shielding portion 320 is preferably located at a position where it can contact the blade portion 130. Therefore, the guide 300 may prevent the strands 1 other than the lower strand from being cut by: the lower part gob 2 is cut by the blade 130, but the gob 1 except for the lower part gob is prevented from contacting the blade 130.
Preferably, the guide 300 is detachable with respect to the sewing machine body 10. Therefore, considering the number and thickness of the pieces to be cut, the pieces can be detached or attached according to the user's needs.
Specifically, according to an embodiment of the present invention, the sewing machine body 10 has a groove which has the same rectangular shape as the upper surface of the support part 310 and is recessed in the length direction. Accordingly, when the support part 310 is inserted into the groove, the support part 310 may be clamped. In addition, the fixing force may be strengthened by attaching the magnetic body of the N pole or the S pole to the upper surface of the recess and attaching the opposite magnetic body of the S pole or the N pole to the upper surface of the supporting part 310. On the other hand, when the guide 300 is to be detached, the inserted guide 300 is separated from the groove by being pulled downward.
Fig. 5 is a view showing a state of a multi-stage cloth used in a car seat in which sewing and cutting processes according to a sewing device of the present invention are completed. Referring to fig. 5, it can be seen that the multi-stage materials are sewn simultaneously and only the lower material is cut short.
For this, the user adjusts the height d of the blade 130 protruding from the surface of the table 20 to the height of the lower gob 2, and positions the shielding part 320 of the guide part 300 above the lower gob 2 and below the gob 1 except for the lower gob. Thereafter, the sewing machine is operated, and the user moves the multi-stage cloth in the width direction at a prescribed speed.
As such, when the sewing and cutting process according to the present invention is performed, the ending is cleanly finished, compared to a seat in which multi-stage billets are cut at the same length, so that the ending quality can be improved.
Although the present invention has been described in detail with reference to the preferred embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the present invention as set forth in the appended claims. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be determined by the claims.
