Description
Technical Field
The invention relates to a sock toe sewing device, in particular to a non-contra-needle type sock toe sewing device and a method.
Background
There are currently three ways to sew the toe of a sock: one is that manual sewing is relatively inefficient; one is that a worker sews the sock through a sewing machine, namely sewing the sock by the traditional machine; the last one is a sock toe sewing device integrally arranged on a sock machine. The invention mainly aims at the sock toe sewing device which is integrally arranged on the sock machine, the sewing device is integrally arranged on the sock machine, the automation degree of the sewing device is high, and the sewing device is popular with customers, and the machine is also called as an integrated sock machine.
The existing integrated hosiery machine aims at the working process of a sock stitch head part, when two semicircular coils of a sock head are overturned and overlapped to be sewn together, the sharp end of a stitch needle arranged on a semicircular stitch fluted disc needs to be notched, a needle point of the stitch needle arranged on the other semicircular stitch fluted disc is accommodated to enter the notch, a needle groove is machined on one side of the stitch needle rod of the sock head to be sewn, the needle groove is matched with the stitch needle on a sock head sewing device, missed stitches can be added in the needle matching process, a hanging ring is hung, needle dropping and the like, the manufacturing difficulty and the technical requirements of the stitch needle are reduced, and the improvement of the sewing quality is an object researched by technical personnel in the field.
Disclosure of Invention
The invention provides a device and a method for sewing the toe of a sock without needle grooves between a sewing tooth needle and between the sewing tooth needle and the sewing needle.
A non-contra-needle type sock head sewing device comprises a head sewing machine and a sewing device, wherein a sewing needle is installed on the head sewing machine, a sewing toothed needle is installed on the sewing device, the sewing toothed needle is connected with a first coil on a sock head in an inserting mode, and the sewing needle is connected with a second coil on the sock head in an inserting mode; the first coil and the second coil are two different coils. The device adopts the sewing tooth needle and the sewing needle to respectively correspond different coils on the sock head of the inserted sock, avoids the needle groove needle aligning structure in the traditional structure, and greatly improves the sock head sewing efficiency. The non-paired needle type sock toe sewing device solves the problem that in a traditional sock knitting machine, socks with different needle numbers need to be knitted, the sewing device with different needle numbers needs to be frequently replaced, namely the number of sewing tooth needles installed on the sewing device is consistent with the number of needles on a needle cylinder of the sock knitting machine under the common condition so as to achieve the technical purpose of mutual matching. By adopting the structure of the invention, the sock head can be directly sewed without changing a sewing device no matter what the needle number of the sock or the needle cylinder of the hosiery machine, because the sewing tooth needle of the invention does not need to be matched with the needle cylinder of the hosiery machine or the needle number of the sock.
The first coil is arranged at the inner side of the second coil. The inner side is knitted according to the knitting rule of the sock, the first coil on the inner side is knitted first, then the second coil on the outer side is knitted until the last coil on the outermost side, and the inner and outer arrangement is more beneficial to separating the sewing tooth needle and the sewing needle from each other, so that interference is prevented.
The stitch gear needle peg graft second coil and first coil on the socks toe simultaneously, realize the technological effect of two coils of a stitch gear needle grafting, reach the technical purpose to the locking of socks toe, prevent to appear taking off or miss the needle problem.
The sewing device comprises a turning semicircular mechanism and a second sewing fluted disc, wherein the turning semicircular mechanism is provided with a first sewing fluted disc which is matched with a first semicircular ring pushing device; the second sewing fluted disc is matched with a second semicircular ring pushing device; the turnover semicircular mechanism rotates around the rotating shaft to drive the first sewing fluted disc to be matched with the second sewing fluted disc; the sewing tooth needle is arranged on the first sewing fluted disc and the second sewing fluted disc.

A sewing method includes the steps of:
step 100: after the first coil is inserted on the sewing tooth needle, the turnover semicircular mechanism turns over to enable the second sewing fluted disc and the first sewing fluted disc to be of an upper-lower structure;
step 200: the sewing needle on the sewing machine is simultaneously inserted with the second coils of the upper part and the lower part formed after the turnover semicircular mechanism is turned over, the second coil at the upper part is positioned on the second sewing fluted disc, and the second coil at the lower part is positioned on the first sewing fluted disc; the first coil and the second coil are two different coils, the sewing needle and the sewing needle are not aligned, and the sewing needle is used for finishing the sewing of the sock head.
Between the steps 100 and 200, the method includes the step 150: the second semicircular ring pushing device pushes the first coil matched with the upper sewing tooth needle of the second sewing tooth disc to the lower sewing tooth needle of the first sewing tooth disc. The upper sewing needle and the lower sewing needle do not need to be aligned, the sewing needle and the sewing needle do not need to be aligned, and the technical structure of inserting and connecting different coils is adopted, so that the needle missing phenomenon caused by the alignment dislocation of the coil transfer between the upper sewing needle and the lower sewing needle and the alignment dislocation between the sewing needle and the sewing needle is solved, and the sewing efficiency is improved.
In the step 100, the number of the sewing tooth needles is 1.1 to 3 times of the number of the coil holes on the first coil.
In the step 100, the number of needle points of the sewing needle is two, and the two needle points respectively puncture the first coil and the second coil or the two needle points respectively puncture the first coil and the third coil.
After the stitching needle completes stitching the sock toe or the stitching needle is inserted with the second coil in the step 200, the second pushing block and the first pushing block respectively push the upper stitching needle on the second stitching fluted disc and the lower stitching needle on the first stitching fluted disc to move reversely, so that the stitching needle is separated from the sock toe.
The invention adopts the sewing tooth needle and the sewing needle which are not aligned through the needle groove, but are directly inserted with different coils to realize the non-aligned needle type sock toe sewing device, thereby realizing that the sock toe can be directly sewn without replacing the sewing device no matter what the number of needles of socks or hosiery machine needle cylinders, namely the sock toe sewing device can be suitable for the needle cylinders with different numbers of needles and the socks with different numbers of needles.
