The present invention relates to a kind of end stitching machine for silk stockings and using method thereof, particularly a kind of be not subjected to the restriction of silk stocking thickness, raw material, behind margin to seam on same the head sewing machine, can carry out the end stitching machine for silk stockings of automatic shearing crotch.

Background technology:

Along with continuing to increase with popular requirement to the socks product quality of cost of labor and workman's flowability is constantly soaring, socks enterprise more and more pays attention to minimizing internal circulation cost and reduces artificial substandard product factor.More new technology reduces operation, and the raising product are imitated, and has just become instantly to knit the unremitting pursue of socks industry.

The end stitching machine for silk stockings of prior art all is the passive methods of making that adopt fixation locus, TC720 type end stitching machine for silk stockings such as the production of Japan high bird machinery club, critical piece and working method are: be evenly equipped with the telescopic hollow movable socks plate of ten build sections at main frame, advance the socks station and going out the socks station, the plastic cement inlet scoop of UNICOM's blower fan is housed from the plastic cement mouth that is automatically connected in hollow movable socks plate tail end, the afterbody of movable socks plate connects with the main frame running part, drives their operations by the programmable controller controls main frame; The stocking leg is enclosed within on the movable socks plate advancing socks station manipulation worker, when the sensor sensing that advances the socks station has put movable socks plate to socks, advancing the cylindrical rubber ring of socks wheel pulls out the undertoe that sucks in the hollow movable socks plate pipe gradually, after undertoe is moved the position that photoelectric sensor sets to, finish into socks bit motion, advancing the socks wheel lifts, because main frame is continuous operation, if completely before reaching next station do not become above-mentioned a series of actions, the operative employee just has to pull out the stocking leg of not finishing into socks, re-start operation, so the class head sewing machine is only applicable to make thinner socks, when being used for thick socks, high stretch hosiery, institutional framework is closely during socks, because the frictional force of the stocking leg and socks plate strengthens, the operative employee can not put the stocking leg within the time of a station, therefore empty socks plate situation can occur, causes yield reducation; Air draught was cut off in the movable socks plate that has overlapped socks was managed when reaching next station, its movable punch head is pushed away undertoe outside the socks plate gradually by the running rail of main frame, Sewing machines is contained on the support, have short groove on the support, short groove in-built a movable pin, movable pin pin body can slide in short groove, movable pin top is a little more than plane on the support, there is one greater than the metallic plate of short well width, be fixed on movable pin top, in case the stop machine frame skids off from short groove, the lower end of movable pin is fixed on the fractional motor rotating disk below the short groove of support, fractional motor is with rotating mode drive activity pin back and forth, make support center on the fractional motor axe movement, Sewing machines with 7000 rev/mins-8000 rev/mins high speed in the support operation that do not stop, the motion of wait socks comes to carry out passive making, sewing path can not change, in addition, because undertoe is subject to backward resistance when making, and the socks body still travels forward with main frame, before the undertoe line speed less than the socks body before line speed, ultra-thin to some, the socks that institutional framework is loose easily produce and make dropped stitch, make spacing inhomogeneous, make out-of-flatness, pull out broken hole, make rear undertoe and upwarp asymmetricly, cause the substandard products socks; Sock piece-end sewing is complete, and main frame directly runs to out the socks station, and the rubber that is driven by fractional motor goes out the socks wheel and is depressed on the socks, through the socks pipe that falls socks are fallen in the case, afterwards, socks need be through manually cutting crotch, counting, and manually cut the difference of crotch green hand and skilled worker's technical merit, make output and quality differ a lot of, therefore, product quality is difficult to guarantee, operating efficiency is very low, and buy a this high-grade import industrial sewing machine, ten thousand yuan/platform of 2-3 easily changes a consumable accessory price also high.Although this type of head sewing machine theoretical yield is higher, but applicable surface is too narrow, be used for making thick socks, high stretch hosiery, institutional framework is very easy to cause because having little time to overlap the empty socks plate that socks produce during socks closely, the actual production of makeing above-mentioned socks product is very low, even can not produce, because it adopts the fixation locus when running up to make, when making different material, easily produce dropped stitch during the different big or small stocking leg, make spacing inhomogeneous, make out-of-flatness, making circular arc upwarps asymmetric, even pull out the situations such as broken hole, defect rate is higher, brought thus artificial, equipment, the energy, the waste of raw material, secondly, the socks undertoe that prior art is produced is difficult to adapt to the toe camber line of different crowd, undertoe discontinuity when therefore wearing, feel under the weather, easily by the toe bursting.
