Description

Electronic striping driving device for circular knitting machine {ELECTRONIC STRIPPING RUNNING GEAR FOR CIRCULAR KNITTING MACHINE}

The present invention relates to an electronic striping (striping) for circular knitting machine, and more particularly, to improve the assemblability by improving the structure of the drive device for driving the striping, and also the upper kiln when knitting a variety of tissue patterns according to the knitted fabric conditions, such as fabric thickness The present invention relates to an electronic stripe driving device for a circular knitting machine, which makes it easy to replace wagama.

In general, the mechanical striping for supplying the color yarn in the circular knitting machine is made of a pure mechanical structure, and the mechanical striping is composed of a selection drum and a plurality of yarn yarn feeding fingers, and a plurality of pin insertion holes are formed on the outer circumferential surface of the selection drum. Inserting a pin into either of these pin insertion holes selects or switches the color yarn supply finger that supplies a specific color yarn.

However, mechanical striping is limited to the pin insertion hole formed in the selection drum, so the range for selecting the color yarn is limited, so it is not suitable for knitting various patterns.If you want to change the knitting pattern, remove the pin inserted in the insertion drum pin insertion hole and change the knitting pattern. The pattern conversion work was complicated, cumbersome and laborious, such as being inserted into the pin insertion hole.

In addition, since the mechanical striping is a purely mechanical structure as described above, there was a problem that frequently occurs, and in particular, the circular knitting machine using the mechanical striping has a problem that the overall production efficiency is lowered.

Therefore, in order to solve the above problems of mechanical striping, the conventional selection drum is replaced with an electronic selection box driven by an actuator according to a signal of a program input to a computer, and the machine operation configuration of the color yarn supply finger is simplified. An electronic striping system was provided to cope with the color shifting device and the butt cam to increase the production efficiency in applying and changing the pattern.

In this electronic striping, the finger of the electronic selection box is operated by an actuator according to a signal of an input computer program, and is configured to advance one of the plurality of color yarn supply plates of the color yarn conversion apparatus to supply the yarn to the knitting needle to knit. Since it is easy to change the knitting pattern, and the knitting of various patterns is possible, high-speed knitting is possible, and since the failure rate is also significantly reduced, the overall production efficiency is significantly improved compared to mechanical striping.

On the other hand, in the knitting portion (hang kiln, hagama) of the circular knitting machine, the needle immersion is changed depending on the knitted fabric conditions such as the fabric thickness, so in order to knit a variety of tissue patterns, the needle immersion must be replaced with the right kiln and hagama.

However, in the related art, the assembly structure of the drive device for driving the electronic striping is very complicated, and thus the assembly is poor. Also, in order to disassemble the striping drive device after assembling the conventional striping drive device, the entire circular knitting machine must be disassembled. Therefore, the following problems have been pointed out because the stripping drive is difficult and difficult to separate.

That is, as described above, in order to replace the upper and lower kilns when knitting various tissue patterns according to the conditions of the knitted fabric, such as the thickness of the fabric, the striping driving device is first separated, and then the needles are submerged in the state of separating the upper and lower kilns in order. It is necessary to assemble a new kiln and hagama to fit, but there was a problem that can not easily replace the kiln and hagama due to the difficulty of separating the entire circular knitting machine to separate the conventional striping drive.

In addition, due to these problems, in the past, various tissue patterns could not be knitted with a single machine. Therefore, in order to knit various tissue patterns, a separate circular knitting machine having a needle immersion of a desired tissue pattern must be manufactured separately. There was an uneconomical problem.

An object of the present invention is to invent the conventional drawbacks as described above, to improve the structure of the striping drive device to improve the assembly, and when replacing the kiln and hagama according to the fabric conditions such as fabric thickness It is easy to disassemble and assemble the hagama, and it is easy to replace the upper and lower kilns with one machine while knitting various tissue patterns, and at the same time, it is possible to reduce the cost and place of installation, thereby enabling economical use. To provide an electronic striping drive for.

In order to achieve the above object, the present invention includes a drive pinion that is fastened to the bottom of the gear with a driving intermediate gear, supports a driven intermediate gear on a main shaft with a race bearing, and is engaged with the driving intermediate gear and the driven intermediate gear. The driven pinion is mounted on the upper plate by bearing housing, the actuator block and the set cam base are bolted to the bottom of the driven intermediate gear, the reset cam base is installed on the set cam base, and the box holder is bolted to the upper plate. Fasten a bolt of a striper box to the lower part of the box holder, and install a chuck block for setting a stripper finger and a stripper finger to supply the upper and lower chambers to the stripper box, the lower block of the actuator block Engage the actuator for activating the chuck block, and set the actuator on the set cam base and reset cam base.
