Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat knitting machine having a structure capable of easily changing the gauge of a knitting needle.

[0002]

2. Description of the Related Art Conventional gauge change of a flat knitting machine requires a large amount of work including replacement of the entire needle bed and replacement and adjustment of cams for driving and controlling knitting needles incorporated in the carriage. However, in general, the gauge change was extremely limited.

[0003]

SUMMARY OF THE INVENTION The present invention solves the problem that it is extremely difficult to change the gauge in a conventionally known flat knitting machine, and makes it possible to change the gauge only by exchanging some parts. It is an object of the present invention to provide a flat knitting machine capable of knitting knitted fabrics of various gauges by one machine.

One or two sheets according to the present invention
A flat knitting machine having a number of needle beds is constituted by a base portion of the needle bed and a sinker portion which is detachably disposed on the base portion and which is formed with a concave portion orthogonal to the sliding direction of the knitting needle. Then, the knitting needle drive shaft inserted into the guide groove of the base portion is connected to the knitting needle inserted into the guide groove of the sinker portion by an intermediate shaft, and a straight shaft or a bent portion at an intermediate position thereof is used as the intermediate shaft. The deformable shaft is used, and when the deformable shaft is used, the deformable shaft is connected to the knitting needle drive shaft and the knitting needle so that the bent portion is arranged in the recess between the base portion and the sinker portion. And

The present invention is a carriageless flat knitting machine capable of high-speed operation proposed by the same applicant as in the Japanese Patent Publication No. 01-012855, that is, a plurality of knitting needles arranged in parallel in one plane. , At least a knitting mechanism comprising a knitting needle guide member that slidably supports the plurality of knitting needles, extends to the left and right along the plane, defines the intervals between the plurality of knitting needles, and forms knitted fabric loops. At least one traveling platform having one set and reciprocating in the left-right direction along the guide member is provided, and the traveling platform is provided with at least one yarn feeding device. An actuator that is individually connected to each one of the needles and that slides the knitting needle, and a storage device that stores a predetermined knitting plan are provided, and the operation of the actuator is the reciprocating motion of the yarn feeding device. The predetermined organization while synchronizing It is extremely effective to use the flat knitting machine and providing a control device that controls based on the image.

The range of gauge change according to the present invention can be applied to all gauges of a flat knitting machine in principle. However, in order to avoid a decrease in efficiency due to the difference in the size of the knitting needles, the range of 5 gauge to 14 gauge is preferable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a plan view of a main portion of an embodiment of the present invention in a flat knitting machine, and FIG. 2 shows A-A in FIG.
Figure 4 shows a cross sectional view at the position. 1 and 2 show a needle bed on a flat knitting machine. The needle bed is composed of a sinker portion 11 and a base portion 21.
Is removable from the base portion 21. The needle bed has a knitting needle 31, a drive shaft 32 for driving the knitting needle 31, a knitting needle 31 and a drive shaft 32.
A predetermined number of intermediate shafts 33 that connect and are arranged according to the knitting width. Each knitting needle 31 has a sinker portion 11
The knitting of the knitted fabric is performed by performing a sliding movement in the front direction and the rear direction along the guide groove 12 provided in the. On the other hand, the drive shaft slides along the guide groove 22 provided in the base portion 21 to give power to the knitting needle. Each of the knitting needles is individually driven by a linear motor or a rotary motor, but description of this actuator will be omitted in this embodiment. The space 13 between the guide grooves 12 of the sinker portion 11 and the guide grooves 2 of the base portion 21
The intervals 23 of 2 do not necessarily match, and the intermediate shaft 33 absorbs the difference. Intermediate shaft 3
3 is provided with a bent portion 34 for providing an offset so as to be able to slide along both the guide groove 12 of the sinker portion 11 and the guide groove 22 of the base portion 21. The bent portion 34 is preferably right-angled in order to ensure a predetermined stroke of the knitting needle. The bent portion 34 is disposed in the recess 20 formed between the portion of the base portion 21 where the guide groove 22 is provided and the portion of the sinker portion 11 where the guide groove 12 is provided.

In FIG. 3, as an example, a sinker portion 11. for 12 gauge is formed so that a 12 gauge knitted fabric can be knitted.
1 is attached to the base portion 21.1, and the guide groove spacing 13.1 of the 12-gauge sinker portion 11.1 and the spacing between the knitting needles 31.1 are 1/12 inch.
In addition, in FIG. 3, the guide groove spacing 23.1 of the base portion 21.1.
The distance between the drive shaft 32.1 and the drive shaft 32.1 is also 1/12 inch. Therefore, in FIG. 3, since the guide groove interval of the sinker portion and the guide groove interval of the base portion are the same, it is not necessary to provide a bent portion for offset on the intermediate shaft 33.1, and a straight shaft is used.

Next, when it is desired to knit an 8-gauge knitted fabric in the needle bed of FIG. 3, the sinker portion 11.1 and the knitting needle 31.1 are exchanged from 12-gauge to 8-gauge and the intermediate shaft 33 is used. It can be realized by replacing and reducing 1. FIG. 4 is a diagram in which the sinker portion 11.2 for 8 gauge, the knitting needle 31.2, and the intermediate shaft 33.2 are attached. Sinker section 11.2 guide groove spacing 1
The distance between 3.2 and the knitting needle 31.2 is 1/8 inch, whereas the distance between the guide groove 23.1 of the base portion 32.1 and the drive shaft 32.1 is 1/12 inch, This pitch deviation is caused by the bending portion 34.1 of the intermediate shaft 33.2.
This is dealt with by reducing the number of intermediate shafts, such as 41, or by absorbing with 41.

In the above embodiment, an example of exchanging the gauge from 12 gauge to 8 gauge has been shown, but it is possible to deal with all gauges by preparing the sinker portion of each gauge and the intermediate shaft.

[0011]

As described above, according to the present invention, it is possible to easily change the gauge by only exchanging some of the parts, and thus it is possible to knit fabrics of various gauges with one knitting machine. As a result, it is not necessary to install many knitting machines of various gauges, and the operating rate of the knitting machines can be increased throughout the year.
