Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a yarn feeding frame for rationally feeding yarn to sewing machines, circular knitting machines, etc.

(Prior Art) Conventionally, yarn feeding racks in sewing machines, circular knitting machines, etc. have had the disadvantage that they are flat and require a large amount of space, and cannot accommodate many thread cones.

(Example) The present invention eliminates the above-mentioned drawbacks, and will be explained below based on the illustrated examples.

1 is a bent rod with a vertical part 1A and a bent part 1
2 is a fixing piece fixed to the lower end of the vertical part 1A, 3 is a support shaft fixed to the lower part of the vertical part 1A, and a U-shaped fixing piece 4 is fixed to the same axis. An adjustment piece 5 is provided in the middle part of the piece 4, and the support piece 4
A screw 6 that penetrates and screws into the lower piece 4A is fixed to the adjustment piece 5, and a knob 7 is fixed to the lower end of the screw 6.

Reference numerals 8 and 8 indicate inclined plates each formed in an inverted T-shape, which are integrally fixed symmetrically to both sides of the bent portion 1B of the rod 1, and furthermore, an inclined plate provided at an angle on the side surface of the bent portion 1B. 8 is integrally formed into a trapezoidal shape via a planar central portion 8B and inclined side portions 8A, 8C, and the central portion 8B of the same plate 8 is connected to the bent portion 1B.
It is fixed in the axial direction.

Further, in the axial direction of the bent portion 1B, the angle α between the plane including the central portion 8B of the inclined plate 8 and the inclined surfaces of the side portions 8A and 8C may be in the range of 0°<α≦60°. preferable.

Further, with respect to the axial direction of the bent portion 1B, the angle β between the horizontal plane including the bent portion 1B and the inclined surface of the central portion 8B in a direction perpendicular to the axial direction of the bent portion 1B is 0°<β≦60°.
It is preferable to set it as the range of.

That is, by setting the angles α and β to the required ranges of 60 degrees or less, it is possible to prevent the bobbin cone 16 from falling off the support frame 11 and the hollow shaft 13, and to make the yarn feeding frame compact, as described later. Furthermore, the extension lines of each hollow shaft 13 can be concentrated at one point, that is, each yarn 17 guided from the hollow shaft 13 can be concentrated at almost one place, and the yarn can be used for various yarn feeding objects such as sewing machines. This allows the yarn to be fed under optimal conditions by keeping the tension uniform.

9, 9... are holes provided at equal intervals in the inclined plates 8A, 8B, 8C, respectively, and the fixing plate 10,
While fixing the conical support frames 11 respectively, the holes 9
A stator 12 is fixed to the lower surface of the .

13, 13... are inclined plates 8A, 8B, 8C, respectively.
The hollow shaft is inserted through the conical support frame 11, the fixing plate 10, and the hole 9, and is also passed through and fixed to the stator 12.

Next, to describe the case where the device of the present invention is applied to a sewing machine, first, the U-shaped fixing piece 4 of the rod 1 is fitted to the rear end of the table 15 of the sewing machine 14, and the adjusting piece 5 is pushed up with the screw 6. The upper piece 4B of the fixing piece 4 is crimped and clamped to the table 15 side, and the rod 1 is fixed to the table 15 via the fixing piece 2.

Next, the thread cones 16, 16... are respectively inserted into the hollow shafts 13, 13... and fitted into the conical support frames 11, 11..., and then the thread ends of the threads 17 are lifted upward and the thread cones 16, 16... are inserted into the hollow shafts 13, 13... 13 Insert into the upper end,
Furthermore, it is made to protrude to the lower end through the inside of the hollow shaft 13,
The thread end of the protruding thread 17 is inserted into a thread guide (not shown) of the sewing machine 14 for use.

In addition to the above-mentioned sewing machines, the present invention can be applied and implemented to general textile machines such as circular knitting machines.

(Effects) As described above, in the present invention, a pair of inclined plates 8, 8 formed in an inverted T shape are fixed on both sides of the upper bent part 1B of the bent rod 1, which is fixedly provided as appropriate, and a plurality of inclined plates 8, 8 are fixed on the same plate. In a yarn feeding frame including support frames 11, 11... and hollow shafts 13, 13... for thread winding cones, an inclined plate 8 provided inclined on the side surface of the bent portion 1B is attached to the center of the planar shape. portion 8B and inclined side portion 8A,
8C into a trapezoidal shape, the central portion 8B of the plate 8 is fixed to the bent portion 1B, and the plane including the central portion 8B of the inclined plate 8 and the side in the axial direction of the bent portion 1B. The angle α between each of the inclined surfaces of the portions 8A and 8C is in the range of 0°<α≦60°, and the horizontal plane including the bent portion 1B in a direction perpendicular to the axial direction of the bent portion 1B and the center The angle β between the portion 8B and the inclined surface is in the range of 0°<β≦60°, and the central portion 8B and the inclined side portions 8A, 8
Hollow shafts 13, 13, .
1, 11... are fixed to the central portion 8B and the inclined side portions 8A, 8C, respectively, it is possible to prevent a large number of thread cones 16 from falling off from the support frame 11 and the hollow shaft 13, and A large number of thread winding cones 16 can be placed on the inclined plates 8, 8, and the device itself is compact and space-saving.
This provides many advantages, such as being able to concentrate on one location, uniformizing the thread tension, and feeding yarn under optimal conditions to various yarn feeding objects such as sewing machines.
