Description

Jig, Clip Actuator and Inner Frame For Quilting Machine, and Quilt Manufacturing Method Using The Same}

The present invention relates to a jig, clip operation unit, and inner frame suitable for a quilting machine used to produce a quilt, and a method of manufacturing a quilt.

Quilted blankets are manufactured by inserting the inner material between the top and bottom outer layers of the quilt and sewing the upper and lower outer pieces and the inner material in a quilted form, and the form shown in Figure 1 is a representative example.

In the case of quilts, cotton is mainly used as the filling.

As shown in FIG. 2, the quilt is made by placing an inner material (20) between the upper and lower shells (11, 12) that are about the size of a finished quilt, and then sewing the upper and lower shells (11, 12) and the inner fabric (20) together using a quilting machine. It is made by sewing in a quilted shape and then sewing the edges.

This manufacturing method is mainly used to produce quilts by supplying the outer shell and inner material in a roll-to-roll manner. The shape of the quilt is limited to a straight line, and if the thickness of the inner material is thick, the edges are compressed and sewn. It requires skilled skills to do this.

In order to overcome the problems of the manufacturing method shown in Figure 2 and manufacture a quilt with various quilt shapes, the three edges of the upper and lower shells 11 and 12 or a portion of the three edges and the remaining edge are sewn as shown in Figure 3. It is made into a bag shape, the inner material is inserted through the entrance part 15 formed by the bag-like outer shell, the upper and lower outer skin and inner material are quilted with a quilting machine, and then the entrance portion is sewn and finished.

This manufacturing method is suitable for producing a blanket with thick filling, but there is a problem in that it is very difficult to insert the filling into the inside through the entrance part 15 and spread the filling evenly inside.

Meanwhile, in order to quilt the outer shell and inner fabric on a quilting machine, the four edges of the outer fabric and inner fabric must be pulled and fixed to the quilting machine jig. This fixing work requires manually manipulating the clips installed along the four sides of the jig one by one, and is done by pulling the outer shell and inner material and fixing them between the clips, which requires skill and has the problem of very low productivity.

Hereinafter, the present invention will be described in more detail with reference to the drawings according to embodiments thereof.

The present invention relates to a quilting machine in which a jig holding the outer shell and inner material moves or a sewing needle moves to make a quilt.

The present invention uses a bag-shaped shell (FIG. 3) sewn together with three edges of the shell disposed on the top and bottom, or including three edges and a part of the remaining edge.

In this embodiment, the inner frame 100 is used to insert the inner material 20 into the entrance portion 15.

The inner frame 100 consists of a first frame 110 and a second frame 200.

The first frame 110 shown in FIG. 4 consists of first and second lateral frames 111 and 112 and a rear frame 120 connected to rear ends of the first and second lateral frames 111 and 112. A reinforcing frame 130 may be installed between each frame as needed, and in this embodiment, the front frame 140 is installed opposite the rear frame.

The first and second side frames 111 and 112 of the first frame 110 are provided with a side pressurizing portion 150 that expands/contracts or protrudes/retracts from the first and second side frames 111 and 112, and the inner frame is the outer shell. When inserted into the inside, the inner side of the shell is elastically pressed according to the operator's manipulation.

According to another embodiment of the present invention, the lateral pressing part 150 is a tube made of a soft material as shown in FIG. 5 (the part located inside the frame is shown with a dotted line) connected to the first and second lateral frames 111 and 112 and the front frame 140. ) is installed according to the The lateral pressurizing portion 150 is inflated by the air injected into the tube and protrudes laterally to elastically pressurize the inner side of the outer shell, and when the air inside is removed, the tube contracts.

6 to 9 relate to an embodiment of the present invention. In this embodiment, the lateral pressing portion 150 is formed by a protruding portion 151.

FIG. 6 is a diagram for explaining the operational relationship of the lateral pressing unit 150 coupled inside the first lateral frame 111, and FIG. 7 is a diagram for explaining the assembly relationship of the lateral pressing unit 150. 8 and 9 are diagrams for explaining the structure of the side pressurizing portion 150.

Figure 6 is shown with the top cover 158 of Figure 7 removed to explain the internal operating relationship, and the top and bottom covers 158 and 159 extend along the longitudinal direction of the first and second side frames 111 and 112. To make the structure easier to understand, part of the length has been omitted without indication.

In this embodiment, the lateral pressing unit 150 operates so that the protrusion 151 protrudes from the first and second lateral frames 111 and 112 toward the inner side of the shell or contracts according to the operation of the first link mechanism 170. .

The protrusion 151 is roughly divided into a first contact end 152 that contacts the inner side edge of the shell, and a first operation end 153 connected to the first contact end 152.

One end is fixed to one of the first contact end 152 and the first operating end 153, and the other end is connected to the first contact end 152 by the first rod 154 sliding inside the other one. ) and the first operating end 153 are coupled to each other, so that the distance between the first contact end 152 and the first operating end 153 is variable.

A second spring 155 is connected to the first rod 154 that is slidably coupled within the first operating end 153 to elastically support the first contact end 152 to the outside (the inner side edge of the shell). .

The elastic force of the second spring 155 is adjusted by the second spring adjustment screw 157 disposed on the opposite side of the side in contact with the first rod 154.

In this embodiment, one end of the first rod 154 is described as being fixed to the first contact end 152, but one end of the first rod is fixed to the first operating end and the other end is fixed to the first contact end 152. It would also be possible to make it slide inside.

Additionally, the first contact end 152 and the first operation end 153 may be connected only by the second spring 155.

The first link mechanism 170 includes a pin 171 installed on the first operating end 153 and a second operating end 172 having an inclined groove 173 into which the pin 171 is coupled. .

The protrusion 151 is guided to protrude or retract toward the inner side edge of the shell by the first guide member 156 installed on the first and second lateral frames 1111 and 112, and this protrusion and retraction are caused by the second operation stage. This is achieved by the interaction between the pin 171 and the inclined groove 173 that occurs as (172) moves forward and backward.

The second operation stage 172 extends along the first and second lateral frames 111 and 112 and has a plurality of inclined grooves 173, and the lateral pressing unit 150 is located at the first and second lateral frames as shown in FIG. 4. A plurality of them are installed at (111, 112), and they simultaneously protrude or retract according to the movement of the second operation stage (172).

One end of the second operating end 172 is connected to the second link mechanism 180 of the rear frame 120, as shown in FIG. 10. The second link mechanism 180 operates like a lever. When the handle 181 is fixed by the fixing latch 182 installed on the rear frame 120, the protrusion 151 is retracted by the second operating end 172. When the handle 181 is dismantled from the fixing latch 182 and rotated, the second operating end 172 moves forward, and thus the protrusion 151 protrudes to pressurize the inner side of the shell. .

Additionally, a front frame 140 is connected to the front ends of the first and second lateral frames 111 and 112.

The front frame 140 may be directly connected to the front ends of the first and second side frames 111 and 112, but as shown in FIG. This fixed guide pin 141, the first through hole 142 of the front frame 140 that is inserted and installed so that the other side of the guide pin 141 does not come off, and the guide pin (142) within the first through hole 142 A third spring 143 elastically supports the other side of the spring 141, and is connected by a third spring adjustment screw 144 coupled to the first through hole 142 to adjust the elastic force of the third spring 143. It is desirable.

The front frame 140 is provided with a groove portion 210 to prevent interference with the pressing portion of the jig for the quilting machine, which will be described later. (see Figure 4)

Meanwhile, the second frame 200 has frames corresponding to the first and second side frames 111.112, the rear frame 120, and the front frame 140 of the first frame 110, respectively, as shown in FIG. 12. And, as shown in FIG. 13, it is hingedly connected to the rear frame 120 of the first frame by the hinge shaft 220.

The inner frame 100 is mounted on the inner frame support 250 shown in FIG. 14.

The lower frame supporting the inner frame support 250 and the jig preparation stand to be described below is not shown.

The inner frame support 250 includes a plurality of first rollers 252 that support the first and second lateral frames 111 and 112 of the inner frame 100 from the lower part, and the inner frame support 250 is provided in the groove of the support coupling portion 254. As it is coupled to the hinge axis 220 of the frame 100, the inner frame 100 is fixed to the inner frame support 250.

The inner frame 100 fixed to the inner frame support 250 lifts the front of the frame located on the upper side of the first and second frames 110 and 200, and the inner material 20 is inserted between them. (Figure 15)

The inner material 20 may be placed between the inner frames 100 by hand, but it is also preferable to use a draw bar 260 as shown in FIGS. 16 and 17. When one end of the inner fabric 20 is fixed to the traction bar 260 and the traction bar 260 is moved from the front to the rear of the inner frame support 250, the inner fabric 20 is placed between the inner frames 100.

The traction bar 260 is provided with a second roller that contacts the bottom and side surfaces of the inner frame support 250. In addition, it is provided with a first clip 262 for fixing the inner material or outer shell to the drawbar and a first coupler 263 for fixing it to the inner frame 100.

When the inner material 20 is placed between the inner frames 100, the traction bar 260 moves again to the front of the inner frame support 250, and then attaches the upper end of the bag-like shell 11 to the traction bar 260. It is fixed to the first clip 262, and the lower shell 12 passes between the inner frame 100 and the inner frame support 250, and the front part of the inner frame is connected to the shell 10 through the entrance portion 15. ) and insert it inside.

Thereafter, when the traction bar 260 is moved rearward, the outer shell 10 moves along the traction bar 260 and the inner frame 100 is inserted into the outer shell.

At this time, the protruding portion 151 of the lateral pressing portion 150 is in a retracted state, and it is natural that the width of the inner frame formed by the first and second frames 110 and 200 is sufficient to be inserted into the inlet portion 15.

When the inner frame 100 is inserted into the outer shell 10, the outer shell is fixed by the first coupler 263 of the traction bar 260 and the second coupler 121 at the rear of the inner frame 100. The first coupler 263 and the second coupler 121 may be configured in various shapes, such as pins and holes, or protrusions that engage each other, as long as the outer shell can be fixed between the two couplers.

Accordingly, the inner frame 100 inserted into the outer shell with the inner material positioned between the first and second frames 110 and 200 is integrated with the traction bar 260.

Thereafter, when the handle 181 of the second link mechanism 180 is separated from the fixing latch 182 and rotated, the second operation end 172 moves forward and the first link mechanism, that is, the pin 171. Due to the interaction of the inclined groove 173, the protrusion 151 protrudes toward the side edge of the inner shell.

The protrusion 151 can be pushed toward the inner frame 100 as the second spring 155 is compressed, and can prevent the edge of the shell from being damaged due to the absolute displacement generated by the first link mechanism 170. .

Accordingly, the outer shell 10 is mounted on the inner frame support 250 in a combined form as shown in FIG. 18, and the four sides are pulled and kept taut.

Afterwards, the hinge axis 220 of the inner frame 100 is separated from the groove of the support coupling portion 254, and the inner frame 100 and the traction bar 260 move forward on the inner frame support 250. It heads to the jig (300).

Figure 18 shows the form before the outer shell and inner material are moved to the jig 300 together with the inner frame 100 and the drawbar 260, and Figure 19 shows the form completely moved to the jig 300.

The jig 300 includes a base member 310 forming four sides; It consists of a plurality of clip members 400 arranged on the base member.

In this embodiment, the clip members 400 are disposed only on the base members disposed on the front and both sides of the base member 310, and both ends of the rear base member are hingedly connected to the lateral base members, as shown in Figure 19. As shown, it can be folded downward, thereby avoiding interference when the outer shell and inner material are moved to the jig 300 together with the inner frame 100 and the traction bar 260.

The jig 300 is fixed by a base fixture to a jig preparation table (not shown) where preparation work is performed before being input into the quilting machine. The base fixing unit may have any known configuration for fixing the jig to the jig preparation table, and may be provided on the jig 300 and/or the base fixing unit.

The jig 300 is provided with a third roller 312 to be guided while sliding on the jig preparation table and the jig holder of the quilting machine.

As shown in FIGS. 21 and 22, the clip member 400 includes a pressure plate 410 that fixes the outer skin and inner material on the base member 310, and one end of the pressure plate 410 is moved toward the base member 310. A 1-1 spring 420 for pressing, a first axis 430 that combines with the pressure plate 410 to act as a rotation axis of the pressure plate 410, and is coupled to both ends of the first axis 430 It consists of a hinge portion 440 fixed to the base member 310.

In this embodiment, the 1-1 spring 420 is installed on both sides of the first axis 430, and the 1-1 spring 420 is surrounded by a cylindrical spring protection portion 422.

The hinge portion 440 includes a pair of sliders 442 installed at both ends of the first axis, and a hinge body portion 446 having a groove portion 444 that guides the sliders 442 in the inner and outer directions of the jig. and a first elastic pressing portion 450 that presses the slider 442 within the groove toward the outside of the jig.

The first elastic pressing part 450 includes a first adjustment hole 452 installed in the hinge main body 446, a first spring adjustment screw 454 installed in the first adjustment hole 452, and the first spring. This is achieved by the 1-2 spring 456 installed between the adjustment screw 454 and the slider 442.

The clip member 400 is operated by the clip operating unit.

The clip operating unit consists of a cam operating unit 510 and a cam moving unit.

Although not shown, the cam moving part is connected to the top of the cam operating part 510 and serves to allow the cam operating part 510 to contact or be spaced apart from the clip member 400.

Such a cam moving part may be formed integrally with the jig preparation table where the preparation process is performed before the jig is input into the quilting machine, or may be installed in a separate frame.

It is also preferable that the cam moving part be connected to a plurality of cam operating parts 510.

The cam operating unit 510 contacts one end of the pressure plate 410 to open the space between the pressure plate 410 and the base member 310, or is a rotating contact part ( 512) and a sliding contact portion 514 that pushes the first shaft 430 toward the inside of the jig. Figure 25 is a cross-sectional view showing a cross section of the rotating contact portion 512.

When the cam operating part 510 moves downward from the top toward the clip member 400 by the cam moving part (FIG. 26(a)), the sliding contact part 514 first moves along the first axis 430 of the clip member 400. ) of the 1-1 spring 420 or the spring protection portion 422 surrounding the 1-1 spring 420 to move the slider 442 inside the jig (FIG. 26(b), (c))

When the cam operation unit 510 descends further, the rotation contact part 512 comes into contact with one side of the pressure plate 410, and the pressure plate 410 rotates about the first axis 430. (Figure 27(a) ), (b)) When the cam operating unit 510 completely descends, the pressure plate 410 is completely opened. (Figure 27(c))

Through the above process, the pressure plate 410 is opened, the outer shell 10 and the inner material 20 are moved to the jig 300, and then the cam operation unit 510 is raised, the pressure plate 410 rotates and the first - 1 The outer shell 10 and the inner material are pressed by the elastic force of the spring.

When the cam operating unit 510 rises and is completely separated from the clip member 400, the outer shell 10 and the inner material are pulled to the outside of the jig by the elastic force of the 1-2 spring 456.

Thereafter, the protrusion 151 of the inner frame 100 is contracted so that the protrusion 151 and the clip member 400 do not interfere when the inner frame 100 is removed from the inside of the outer shell.

When the inner frame 100 is completely inserted into the outer shell 10, it is natural that the protrusion 151 and the clip member 400 are placed in positions where they do not interfere with each other.

Since the clip member 400 simultaneously holds the outer shell 10 and the inner material 20, it is possible to remove only the inner frame 100.

It is also desirable to manually fix the outer shell and inner material to the rear base member of the jig using separate clips, and to secure the outer skin and inner material by arranging the same clip members as the clip members installed on the front and lateral base members. It may also be possible to fix it.

Afterwards, the jig on which the outer skin is fixed is moved to the quilting machine and fixed, and the outer skin and inner fabric are sewn with the quilting machine.

When the sewing work is completed, the jig is separated from the quilting machine, moved to the jig preparation table, and the clip member is opened to separate the outer shell and inner material from the jig to complete the quilting work.
