Description
Technical field
The present invention relates to the apparatus for sewing a thread chain into a seam of overlock machine.At length say; The apparatus for sewing a thread chain into a seam that relates to a kind of like this overlock machine:, the operator pulls to cloth on one side after sewing finishing and makes direct of travel the place ahead, moves to operator front one side Yi Bian manually retract; Subsequently; The idle loop that forms of linking to each other with cloth in the time of will binding off the sewing finishing of occasion to the cloth ora terminalis is pulled out to a side in front of the operator of the needle plate that contains to fall pin portion, holds it on the idle loop holding unit that is arranged at a side in front of this operator, simultaneously idle loop is cut off from cloth; Under this state; Automatically be sewn in the stitching of the cloth of then making (below be called the back stitching seam) with remaining on idle loop on the idle loop holding unit, burst forth, relate in particular to and be suitable for the device that the idle loop in the double-needle cup seaming machine sews up with the stitching of the seam portion that prevents to begin.
Background technology
On the needle plate in the apparatus for sewing a thread chain into a seam of this double-needle cup seaming machine; Be formed with the edge with make direct of travel roughly the direction of quadrature arrange and comprise respectively inside and outside two needle trays that fall with the corresponding pin portion that falls of crosspointer, the needle tray that respectively falls from the leading edge edge of these needle trays that fall simultaneously extends inside and outside two needle board claws to making direct of travel.These inside and outside two needle board claws the regulation make the time from below partly support being positioned at inside and outside two clothes that fall between needle tray; Thus; Having the effect that prevents that this cloth part from off-line taking place because of the part falls into or cause the cloth local eminence to become the semicircle cone that processing is worsened because of the tension force of line, is effective obtaining good making aspect the processing.
Yet; In the apparatus for sewing a thread chain into a seam of double-needle cup seaming machine with inside and outside two needle board claws; Owing to after sewing finishing, cloth pulled to and makes direct of travel the place ahead and manually retracting when moving in front of the operator side (making the direct of travel rear side); Form the big idle loop of width and get in the inboard needle tray that falls extracting the back from needle board claw to be wrapped in inside and outside these state on needle board claw; The pin portion leading edge that falls of needle tray of falling from this inboard pulled into a side in front of the operator, becomes the state that is maintained on the idle loop holding unit, therefore; When crosspointer carries out once reciprocating motion (Sewing machines revolves and turns around) for next cloth is made; Last looper thread and following looper thread are introduced in the pin portion that falls of the inboard needle tray that falls through the needle tray that falls in the outside with needlework under not shown following looper effect, then when crosspointer moves back and forth (second needle tracking) again, the outside be needled into said upward looper thread and following looper thread sews up; Its result; Behind second needle tracking, the beginning of back to back tailoring cloth seam end arrive pin portion between early stage formed idle loop be curled into the dumpling shape at the cloth end place of the beginning of cloth seam end, produced the problem of the back stitching seam that can not stipulate.
The reason of this problem is, last looper thread and following looper thread have been wrapped on the inboard needle board claw of the needle plate that is formed in the double-needle cup seaming machine and the very big width of formation.As the method for eliminating the problems referred to above that this reason causes; Technology was as the special public clear 56-28554 communique of Japan disclosed in the past; A kind of like this structure has been proposed: after the sewing finishing,, make said inboard needle board claw from front of the operator, retiring moving in a rear flank with the parallel progressive position of outside needle board claw Yi Bian manually retract when moving in front of the operator side when one side granny rag material; Make idle loop not be formed on inboard needle board claw; Only be formed on the needle board claw of the outside, thus, fall from the outside pin portion leading edge that falls of needle tray of idle loop be pulled out to a side in front of the operator; Or as japanese kokai publication hei 9-182884 communique discloses; Proposed to be provided with the structure of the idle loop guide way of driven in rotation formula: after sewing finishing; When one side granny rag material manually retracts on one side when moving in front of the operator side; Through making cloth begin action with the idle loop butt, thereby this idle loop released the rear foreign side of making direct of travel that is directed to outside needle board claw leading section.
In addition; As japanese kokai publication sho 56-104696 communique discloses; A kind of like this structure has been proposed: make the direct of travel anterior position at inside and outside two needle board claw leading sections; On the same plane that is positioned at inside and outside two needle board claws, form the fixed salient of idle loop deflection usefulness with needle plate, and fixed salient have the 1st guide cam face and the 2nd guide cam face; Cloth moves and when inside and outside two needle board claws are extracted idle loop to the pulling of making direct of travel after along with sewing finishing; Said the 1st guide cam face gathers these lines with the ply-yarn drill merging of these idle loops of formation, and said the 2nd guide cam face is along with the idle loop slip is moved and made to said cloth manually retracting of a side in front of the operator after this, in the needle tray that falls outside this idle loop immigration is directed to.
But, in above-mentioned technology in the past, as the flat 9-182884 communique of the public clear 56-28554 communique of spy and Te Kai proposes; In the structure of movable parts such as inboard needle board claw that has used the advance and retreat formulas or revolving idle loop guide way; The driving mechanism of this movable part self not only to be arranged, and the synchronous interaction mechanism that synchronously makes movable part action usefulness with the action of handling the needle of Sewing machines will be arranged, therefore; The complex structure of single unit system causes cost to increase.In addition; Foreign matters such as line bits are wrapped on the movable part easily; In the occasion that this wound foreign matter takes place; This movable part can not carry out compulsory exercise smoothly and fully, and its result can not eliminate on the cloth end of the residual beginning seam end that is crimped onto cloth of idle loop and the problem of the back stitching seam that can't stipulate reliably.
In addition; Open clear 56-104696 communique proposes like the spy; In fixed salient of idle loop being partial to usefulness and structure that needle plate is integrally formed; Compare with the structure of having used above-mentioned movable part; Though structure is very simple and can reduce cost, the fixed salient of idle loop deflection usefulness be formed on inside and outside two same planes of needle board claw on the position, so between the 1st guide cam face of this fixed salient and two needle board claws, must be provided with as the operator cloth is spurred the gap that can let idle loop pass through when mobile to making direct of travel the place ahead; Therefore, the top location of the 1st guide cam face will be than the leading section of inboard needle board claw more away from making the direct of travel front side.In addition; Be formed in the structure at the back side (making the face of direct of travel front side) of fixed salient owing to make the idle loop guiding of having gathered line by the 1st guide cam face move into fall the 2nd guide cam face used in the needle tray of the outside; Therefore; In order not carry out idle loop transfer towards the 2nd guide cam face by the strong hand and successfully, can not make the end of fixed salient outstanding to foreign side too much from the 1st guide cam.
Therefore; The effect that idle loop is extracted from needle board claw and make the idle loop guiding move into fall effect in the needle tray of the outside can to receive after the sewing finishing about the move operation technical ability of operator to cloth; According to operative skill how, to have and can not idle loop successfully be extracted from the needle board claw or idle loop can not successfully lead and moves into the outside and fall in the needle tray and bring for the back stitching seam of regulation to hinder this possibility problem of higher.
Summary of the invention
The present invention makes in view of the above problems; Its purpose is to provide a kind of apparatus for sewing a thread chain into a seam of overlock machine; Do not use the movable part of all just can integral body be made simple structure and low cost; And, irrespectively make idle loop move into the guiding that the outside falls in the needle tray with operator's operative skill and move into reliable effectization from the effect of extracting of needle board claw and idle loop guiding thereof, and the back stitching that can reliably and well stipulate all the time seam.
