Description

Quilting {Quilting machine}

This article relates to a quilting machine which is formed with several stitches parallel to the fabric by installing several tens to hundreds of needles in a row.

In particular, the purpose of this paper is to improve the speed of quilting work very quickly and to make the work more convenient.

As is well known, the quilting machine lifts and drives many needles at the same time to form several rows of parallel lines.

However, in order to narrow the sequel interval, the interval between needles should be narrowed, but because the device for supplying the lower thread was large, some space was needed, so there was a limit in narrowing the installation interval of the needles. Therefore, the needle is installed in the diagonal direction of the quilting machine and the fabric is passed through in the longitudinal direction of the quilting machine to enable the narrowing of the quilting work.

The problem with the stitching method described above is that it takes a lot of stitching time, and the needle can be sewn in a diagonal direction so that the width of the stitch can be narrowed at a time. When you work, you have to go through the quilt repeatedly about five times to be able to quilted the entire width.

In addition, the conventional quilting machine was only able to work in a straight quilted line, that is, the sewing line in a straight line form, and in recent years, a part of the stitched line at the same time as a straight line by reciprocating a part of the head where the needle is installed 'It has been developed to be able to form a curve like a shape, but in this case it is only possible to repeat the straight line and the curved portion once or twice, and further repetition is impossible structurally, there is no room for deformation other than simple repetition It was a very simple form of quilted work.

In view of the above-mentioned problems, the present proposal has newly constructed a power transmission device of the quilting machine, which enables the quilting work at narrow intervals while passing the fabric perpendicular to the longitudinal direction of the quilting machine. It is designed to allow a wide variety of types of quilted work, such as selectively enabling it.

Therefore, when the transmission shaft 75 and the rotating plate 77 rotate by the drive shaft 13, the rod 78 raises and lowers the connector 79, and the one-way bearing 72 reciprocates by the operating period 74. Repeatingly, the reciprocating drive shaft 70 rotates in one direction so that the case 10, 10 'and the north drive unit 50 reciprocate by the rotating plate 71 and the rod 72 installed at both ends.

In the figure, reference numerals are 90 for the manual handle, 91 is a post for installing the fabric pressing plate 33, 92 is a fabric pressing plate support.

It looks at the operation of the present invention configured as described above.

The fabric is pushed between the fabric pressing plate 33 and the fabric support plate 34 in the perpendicular direction of the quilting machine 1, and the end is installed at the rear end of the case so as to be fed to the discharge roller (not shown) that pulls the fabric. In this state, the driving of the quilting machine 1 is started, and the drive shafts 13 and 13 'are rotated by the transmission action of the belt 61 and the chain 62 by the rotation of the motor 60.

As a result, the guide swing shafts 14 and 14 'and the needle drive shaft 21 connected by the drive shafts 13 and 13' and the chains 16 and 23 are rotated. Rotation of the rod 18 eccentrically connected to the outer bulb 17 when the rotation is to move one side of the swing interval 42, the swing guide 42 is lever lever movement around the support 41, the seal guide plate (40) (40`) is rocking up and down.

In addition, the needle driving shaft 21 rotates while the rod 28 eccentrically connected to both ends of the rotary holes 27 moves up and down, thereby being connected to the rod 28 to hold the needle elevating rod 25. The elevating movement of the needle bar 25 is to be elevated, and eventually the needle bar 30 and the needle 30 fixed to the connecting plate 31 is to be lifted while the sewing operation.

As the fabric is passed in the direction perpendicular to the quilting machine (1) as described above, the quilting work is progressed so that the entire width of the conventional fabric can be quilted at once. Considering all the different rows of needles are installed in a wide but displaced position, it is possible to reduce the installation interval of the needle by that much, so that it is possible to work in a right direction, thereby improving the working speed very much.

The important function of this paper is that it is possible to curve curvature, and to be able to simultaneously curve and straight quilted, which means that the whole of the quilted quencher 1, including the case 10 (10`), can move in the longitudinal direction of the quilter 1; Because it is configured to be.

That is, the LM guides 12 and 36 are provided on the bottom surfaces of the installation cases 51 and 51` of the case 10 (10 ') and the north driving part 50, and are installed on the cases 10 (10'). Since all the devices move together with the case 10 (10 ′) and the driving unit 50 is also configured to be connected with the case 10 (10 ′), the needle 3 and the north driving unit ( 50) reciprocates left and right, 'Curved quilted forms are possible.

In particular, this case is divided into two cases 10 (10`), each configured to transmit power, so that the power for reciprocating motion can be simultaneously connected to or disconnected from the two cases (10) (10`). Only the case 10 on one side can be selectively connected to the power, such as reciprocating movement, more various types of quilted work is possible. 'Shape or' Can be quilted in a straight line or a full curve, or ' 'Of course, some straight lines and some curves appear alternately,' 'You can do it one by one like a brother, and if you increase the distance of reciprocating motion,' It is possible to quilt in the form of overlapping curves and straight lines like 'shape'.

As described above, this paper makes it possible to quilt the entire width at once with narrow intervals while entering the fabric in the direction perpendicular to the quilting operation. It is possible to represent a straight or curved quilting line in a variety of forms, such as can be said to be an excellent design that greatly improved the performance and work efficiency compared to the conventional quilting.
