Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for sewing a large sewn product such as a futon.

[0002]

[Prior Art]

 Conventionally, a gate-type machine frame was erected on a bogie that moves in the front-rear direction, and a sewing machine main body moving mechanism that horizontally moves the sewing machine main body in the horizontal direction was provided in the horizontal section of the gate-type machine frame. As the main body moving mechanism, there is known a futon sewing device having a structure in which the hook portion mounted on the upper surface of the carriage is moved in synchronization with the main body of the sewing machine in the left-right direction so that it is always at the lower position of the sewing machine main body.

[0003]

[Problems to be solved by the device]

 In the above-described futon sewing machine, in addition to driving the sewing machine body and the hook portion in conjunction, the sewing machine body and the hook portion must be moved accurately in synchronization with the left and right directions, which complicates the structure. There is a point. In addition, since the futon tension stand is installed below the gate type machine frame, the futon can be put in and out only in the front-rear direction because it is blocked by the vertical part of the edge of the gate type machine frame. There was a problem that it was restrictive and inefficient.

The problem to be solved by the present invention is to eliminate these conventional problems, to move the main body of the sewing machine and the hook portion with a simple structure, and to sew the futon easily. To provide a device.

[0005]

[Means for Solving the Problems]

 The gist of the present invention, which has solved such a problem, is to provide an upper base movably in the left-right direction on a lower base that moves in the front-rear direction, provide a cantilevered long horizontal arm on the upper base, and freely move the horizontal arm. The sewing machine main body is vertically movable near the end, and a hook section is provided on the upper surface of the upper base that faces the sewing machine main body, and a sewing machine drive mechanism that synchronously drives the sewing machine main body and the hook section is provided on the upper base. In addition, the sewing machine is provided with a sewn product tension stand for suspending a sewn product such as a futon above the hook portion of the upper table.

[0006]

[Action]

 In this invention, since the sewing machine main body, the hook portion and the sewing machine drive mechanism are all mounted on the upper base, the sewing machine main body moves to the left and right as the upper base moves left and right, and the upper base moves back and forth. The hook portion can be freely moved back and forth and right and left, and can be sewn in a desired pattern on a futon that is stretched on a sewn material stretcher fixed to the floor.

In the present invention, since the sewing machine main body and hook section are attached to the horizontal arm of the upper table and the upper table top, and both move left and right by the movement of the upper table, there is no horizontal movement mechanism for each sewing machine main section and hook section. The sewing machine body and hook section can be moved left and right in synchronization with a simple structure. Since the horizontal arm is cantilevered for attaching and detaching sewn items such as duvets, large sewn items such as duvets can be put in and taken out from a wide angle range, and can be easily attached and detached.

【Example】

 An embodiment of sewing a futon according to the present invention will be described below with reference to the drawings. FIG. 1 is a front view of an embodiment, FIG. 2 is a plan view showing a drive mechanism for a lower stand and an upper stand, FIG. 3 is a side view of the embodiment, and FIG. 4 is a front view showing a sewing tension stand.

In the figure, 1 is a lower base, 2 is an upper base, 3 is a horizontal arm provided on the upper base 2, 4 is a sewing machine main body, 5 is a hook portion, 6 is a sewing machine drive mechanism, 7 is a sewing material tension stand, 8 Is the floor.

In the figure, 10 is a running rail for moving the lower base 1 back and forth, 11 is a fixed screw shaft installed in the front and rear, 12 is a rotary nut screwed with the screw shaft 11, 13 is a rotary nut 12. A belt to be rotated, 14 is a motor for moving back and forth for mounting the belt 13 on the lower base 1, 15 is a rail for left and right traveling provided on the lower base 1, 18 is a rotary screw shaft attached to the lower base 1, 19 is the same rotary screw shaft A motor for rotating 18, a nut 20 mounted on the upper base 2 screwed onto the screw shaft 18, a substrate 21 on which the sewing machine main body 4 is attached, 22 a pivot of the same substrate 21, and 23 vertically moving the sewing machine main body 4. A cylinder, 24 is an L-shaped link, 25 is a pivot of the L-shaped link 24, 26 is a connecting plate that connects the tip of the L-shaped link 24 and the substrate 21, 27 is a sewing machine drive motor, 28 is an upper shaft, 29 Universal joint , 31, 31 and 32 are belts, 33 is a lower shaft, 34 is a tension frame of the sewn material tension stand 7, and 35 is a peripheral clamp of a futon using a cylinder (not shown).

In this embodiment, when the longitudinal movement motor 14 is operated, the rotary nut 12 rotates via the belt 13, and the rotary nut 12 moves with respect to the screw shaft 11 to move the lower base 1 in the longitudinal direction. Let

When the motor 19 is actuated, the rotary screw shaft 18 rotates, and the screw shaft 18 is screwed onto the rotary screw shaft 18 and attached to the upper base 2, and the nut 20 moves in the left-right direction together with the upper base 2. As a result, the sewing machine body 4 and the shuttle 5 can be moved back and forth and left and right.

When the sewing machine drive motor 27 is operated, the sewing machine main body 4 is operated via the belt 30, the upper shaft 28, the universal joint 29, and the belt 32. At the same time, the shuttle 5 is operated in synchronization with the sewing machine main body 4 via the belts 30, 31 and the lower shaft 33.

Next, when the cylinder 23 is operated, the base plate 21 and the sewing machine main body 4 attached to the base plate 21 are rotated about the pivot shaft 22 through the L-shaped link 24 and the connecting plate 26, and the needle of the sewing machine main body 4 is rotated. , And the futon is attached to the sewing material tension base 7 in a state in which it is spread between the upper surface of the lower base 1 and the needle of the sewing machine main body 4.

To attach and detach the futon, the futon is introduced from a wide range to the tension frame 34 of the sewn material tension base 7 from either the free end side of the horizontal arm 3 on the right side of the sewing device or the front front side. The peripheral clamps 35 are attached to the tension frame 34. It can be easily removed by reversing the operation.
