Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a quilting machine.

(Prior Art) This type of quilting machine is exemplified by U.S. Pat. No. 62-159159, which was previously filed by the present applicant. In this quilting machine, as shown in FIG. 4, FIG. 5, and FIG. A plurality of rollers 1 that sandwich the material C to be sewn and transport it in the front and back direction.
A frame body 120 to which 25 is assembled is provided so as to be movable in the left and right direction. And the frame body 120
is adapted to be driven left and right by a frame drive motor M1 arranged and fixed on the base 100 on the side thereof.

Further, the roller 125 is rotationally driven by a roller drive motor M2 arranged and fixed on the base 100 on the side of the frame 120.

(Problem to be solved by the invention) Therefore, in the quilting machine,
Since the frame drive motor M1 and the roller drive motor M2 are arranged and fixed on the base 100 of the quilting machine and protrude to the sides of the frame 120, the entire device becomes larger in the width direction. ,
There were problems such as being bulky during transportation and taking up extra installation space within the factory.

Therefore, the purpose of this invention is to fix the frame drive motor and roller drive motor to the bottom of the base,
The objective is to reduce the width dimension of the quilting machine.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the quilting machine of the present invention includes a base provided with a large number of sewing needles that move up and down to stitch patterns on the material to be sewn;
A frame body is provided on the upper surface of the base to which a plurality of rollers are assembled for sandwiching and transporting the material to be sewn in the front and rear directions, so as to be movable in the left and right direction, and a threaded rod is connected to the rotation shaft on the lower surface of the base. A support arm having a nut portion that penetrates the base and is threadedly engaged with the threaded rod is provided on the lower surface of the frame, and a support arm is protruded from the lower surface of the base. A roller drive motor is disposed in the roller drive motor, a toothed belt wheel or sprocket is slidably but non-rotatably attached to the rotating shaft of the roller drive motor, and the toothed belt wheel or sprocket is attached to the roller. The feature is that a toothed belt or chain is hung between the attached toothed belt wheel or sprocket.

(Function) According to the present invention, since the frame drive motor and the roller drive motor are disposed on the lower surface of the base, these two motors do not protrude to the sides of the base. Further, since the threaded rod connected to the rotating shaft of the frame drive motor is screwed into the nut portion of the support arm, the volume of this portion can be reduced and it can be easily stored in the lower surface of the base. Furthermore, even if the frame or roller moves, the toothed belt or chain slides the toothed belt wheel or sprocket on the motor side along the rotation axis due to its centering action, and the center of both toothed belt wheels or sprockets is adjusted. Match.

(Example) An example of a quilting machine embodying the present invention will be described below.

As shown in FIGS. 1 and 2, on the upper surface of a base 10 on which a large number of sewing needles 11 that move up and down to pattern-sew the material C to be sewn, a drive means for the needles, etc., the material C to be sewn is mounted. A frame body 20 is provided so as to be movable in the left-right direction. A frame body 20 is assembled with a plurality of rollers 25 that sandwich and transport the paper in the front-back direction. The three rear rollers 25 are connected to the three gears 26 shown in FIG. The two gears are rotated simultaneously by two gears (not shown).

The frame body 20 includes a pair of front and rear steel members 21 and a connecting member 2 that connects both left and right ends of the steel members 21 to each other.
2. Support legs 21a are protruded from the lower surface of both left and right ends of the steel material 21, and the support legs 21a support the frame 20 and move left and right on the guide rail 10a fixed to the upper surface of the base 10. It is designed to slide.

A support arm 2 is provided on the lower surface of the left connecting member 22 in FIG.
3 is provided. A nut portion 23a facing in the left-right direction is provided at the lower end of the support arm 23, and the nut portion 23a is provided with a frame drive member arranged and fixed on the lower surface of the base 10 below the frame member 20. A threaded rod 30 connected to the rotating shaft of the motor M1 is screwed from the left and right directions.

Further, a roller drive motor M2 is arranged and fixed on the lower surface of the base 10, which is below the right side of the frame 20 in FIG. As shown in FIG. 3, a shaft 40 facing left and right is connected to the rotating shaft, and a toothed belt pulley 50 having flanges on both sides is attached to the shaft 40 so as to be slidable left and right. has been done. The toothed belt wheel 50
A toothed belt 60 is hung between the roller 25 and the toothed belt wheel 55 fixed to the end of the rear roller 25 through an opening 10b provided in the upper surface of the base 10. 25 to rotate. Incidentally, a protrusion 41 is formed on the outer circumferential surface of the shaft 40 along its longitudinal direction to prevent the toothed belt pulley 50 from idling.

In the quilting machine configured as described above, the threaded rod 3 connected to the frame drive motor M1
In this example, since the nut portion 23a is screwed from the left and right directions, when the frame drive motor M1 is rotationally driven, the threaded rod 30, the nut portion 23a, and the support arm 23 are connected from the back side of the base 10. Through this, the frame body 20 can be driven left and right on the base 10.

Further, when the roller drive motor M2 is rotationally driven, each roller 25 can be rotationally driven from the back side of the base 10 via the shaft 40, toothed belt pulleys 50, 55, and toothed belt 60. Note that when the frame body 20 is driven left and right, the toothed belt 55 also moves left and right. Since the toothed belt 60 slides left and right following the toothed belt pulley 55 so as to match the toothed belt pulleys 50 and 55, the toothed belt 60 does not come off from the toothed belt pulleys 50 and 55.

And in this quilting machine,
Since the frame drive motor M1 is arranged and fixed on the lower surface of the base 10 below the frame 20, and the roller drive motor M2 is fixed on the lower surface of the base 10 below the frame 20, The entire device can be made smaller in the width direction. Therefore, the problem of bulkiness during transportation can be solved, and the installation space within the factory can also be omitted.
It should be noted that the present invention is not limited to the above-described embodiments, and may be implemented by using a sprocket instead of the toothed belt wheel 50, a chain instead of the toothed belt 60, etc. without departing from the spirit of the present invention. It may be implemented with appropriate changes within the range.

(Effects of the invention) As detailed above, in the present invention, the frame drive motor and roller drive motor are fixed to the lower surface of the base, which is below the frame, so that the widthwise dimension of the quilting machine can be made smaller, and the volumes of the threaded rod and the nut portion of the support arm can be reduced. In addition, in order to drive the rollers, a toothed belt was hung on the toothed belt wheel, or a chain was hung on the sprocket, so
With a simple configuration, the excellent effect of aligning the centers of both toothed belt wheels or sprockets is achieved.
