Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a quilting machine which makes it possible to feed the fabric to be sewn entirely by means of a belt.

A quilting machine is a machine that continuously sews thick long fabric using multiple needles. 1. A quilting machine is a machine that continuously sews thick long fabric using multiple needles. 1. A quilting machine is usually equipped with a pair of upper and lower rollers close to the operator to feed the thick long fabric forward. A rotatable cylinder takes up the long fabric, and feeds the entire long fabric to the rollers.The rotation of the rollers sends the fabric forward, and multiple stitches are activated to stitch the long fabric at predetermined intervals. There are many configurations that form.

In recent years, in order to meet the demand for a wide variety of products in small quantities, the fabric that forms the seams is sometimes not long, and therefore the fabric is sometimes fed directly into a quilting machine for sewing work without being wound onto a cylindrical feed cylinder. It was happening. When such short fabrics are fed into a lamination machine for sewing, it requires skill to carry out forward feeding using only a conventional pair of upper and lower rollers, making it difficult to form beautiful seams.

The present invention allows even short fabrics to be easily fed into the machine.
The purpose of the present invention is to provide a quilting machine capable of producing beautiful seam shapes. In order to achieve this object, the present invention uses a belt tracker to smoothly feed the dough.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be fully described below with reference to the accompanying drawings.

A horizontal plate 6 is supported by a column 8 on the top surface of a table 4 equipped with legs 2.
It is provided on the table 4 so that it is supported by the table 4. Code 10.
Reference numeral 10 denotes a pair of side plates, which are rotatably supported for a pair of shirts) 12, 13i, and each of the shirts) 12, 13 has a plurality of first groups 14. A second upper spool group 16 is attached, and an upper feed belt 18 is wound around each of the two pre-groups 14 and 16. The side plate 10 is a shirt) 1
2.13', it opens and closes in a vertically movable manner around its rear shaft portion 20. The upper feed belt 18 is wrapped around an upper shaft feed roller 53 attached to an upper feed shaft 52, a third upper sill 22, a fourth upper sill 24°, a second upper pref 16, a first upper pref 14, etc., which will be described later.

A part of the belt contacts the upper belt idler 26, and its tension is adjusted.

FIG. 2 is a route diagram of the belt drive device of the present invention housed in case C. Table 4VC motor M is installed,
A drive belt 34 is wrapped around the pre-shaft 28 and a main shaft pre-shaft 32 attached to the main shaft 30. The main shaft 30 has a feed rod 3
A feed cam 38 provided at 6 is eccentrically mounted. A stepped screw 42 with a nut provided at the end of the arm portion 40 of the feed rod 36 is slidably fitted into a long groove 48 formed in a feed port adjustment lever 46 that constitutes a part of the clutch adjustment lever 44 .

A one-way clutch (not shown) has a lower feed shaft 50 with a lower shaft feed roller 51 inserted and fixed to the clutch adjustment lever 44.
Clutch adjustment by the action of Leno:! 44 so as to be rotatable only in the direction of the arrow, is attached to the end of the lower feed shaft 50, and has an upper shaft feed roller inserted and fixed thereto via a gear joint (not shown). The lower shaft gear 56 that meshes with the lower shaft gear 54 mounted on the end portion of the lower shaft gear 56 rotates in the same direction as the lower feed shaft 5o rotates. Feed lower shaft 5o
The upper shaft gear 54 meshes with the lower shaft gear 56 due to the rotation of the upper shaft gear 54.
rotates in the direction of the arrow, which is the opposite direction.

Therefore, the rotation of the motor M is controlled by the motor preamp 28 and the belt 34.
When the main shaft 30 rotates, the eccentric feed cam 38 causes the feed rod 36 to swing in the direction of the arrow, and the step screw 42 at the end of the feed rod 36 rotates through the long groove 4 of the feed adjustment lever 46.
Since it slides inside 8, the feed port can be adjusted. 46 also swings in the direction of the arrow, and when the clutch adjustment lever 44 fully engages the one-way latch and rotates the feed lower shaft 50 and the lower shaft gear 56 in the direction of the one-way arrow, the upper shaft gear meshed with this gear. 54 rotates in the direction of the arrow together with the upper feed shaft 52. Therefore, the lower shaft feed roller 51 that is fitted and fixed to the lower feed shaft 50 and the upper shaft feed roller 53 that is fitted and fixed to the upper feed shaft 52 are also attached to the shaft 5.
0.52 and rotate in the same direction, and as will be described later, it becomes possible to sandwich the fabric W between both rollers and send it out.

Next, referring to FIG. 3, the rotation of the lower feed belt 58 will be explained. The lower feed belt 58 moves in the direction of the arrow by the rotation of the lower feed shaft 50 and the lower shaft feed roller 51 as described above. The code 6o is the first lower series, 62 is the second lower series, 6
4 is a third lower sill, and the lower belt eye P 66 contacts a part of the lower feeding belt 58 and is useful for adjusting the tension of the lower feeding belt. The lower feed belt 58 moves in contact with the upper surface of a throat plate 74 provided on a horizontal support plate 72 that is constructed between a front T plate 68 and a rear lower plate 70 that are erected on the table 4. Throat plate 7
A needle 76 and a needle 78 are arranged so as to correspond to each other across the needle 4.

Next, the effects of the present invention will be explained. Figures 1 and 3
In the figure, a plurality of pairs of upper feed belts 18 and lower feed belts 58 are arranged at relative positions to each other. A sewing thread (needle thread) 80 is attached to the plurality of needles 76 via a thread guide 82.

The fabric W to be sewn is held between the upper feed belt 18 and the lower feed belt 58 in FIG. For this purpose, yellowtail group 14
．． The side plate 10 supporting the 16'iz shirt) 12.13 is rotated upward about the rear shaft part 20 to form an appropriate gap, and the fabric W'& is pushed into this gap, After returning the side plate 10 to its original position, when the motor M is activated, the upper feed shaft 52. The upper shaft feed roller 53, the lower feed shaft 50, and the lower shaft feed roller 51 rotate in a predetermined direction, and the upper and lower feed bells (18.58i) are moved while being tied to a plurality of yellowtails. Vertical feed belt 18.5
8, the fabric W moves in the direction of arrow A and is held between the upper axis feed roller 53 and the lower axis feed roller 51.
Also, the fabric is being moved by a plurality of needles 76 with needle threads attached and a plurality of loops 78 with all bobbin threads attached at the position of the moving needle [76].
Multiple rows of stitches are constructed by the operation of .

As described above, since the quilting machine of the present invention is configured to feed the fabric with a belt, it is possible to smoothly feed fabrics with the rollers 53 of the upper shaft 52, even short fabrics, rather than a specific long fabric as in the past. It is fed between the rollers 51 of the lower feed shaft 50, making it possible to perform so-called quilting stitches.
