Below the rearward end of each conduit 24, be provided with manual manual pulling off device, be positioned at conduit 24 with the end of a thread that will insert (that carried out just now makes) the suture T that leads in looper device R.As this manual pulling off device, the aggrandizement apparatus of the amount of leaving behind of leave behind member and increase line that the TOHKEMY 2002-317374 communique that for example can use the applicant to apply for is put down in writing etc.These members are that everybody is known, and therefore, in this description will be omitted, are not limited to above-mentioned structure certainly.
Below, the action when carrying out the chain-type stitch operation in the chain sitch sewing machine of the present utility model that constitutes said structure on the sewn object of tubular is described.In each conduit 24, be placed with the color of drawing a plurality of spools on being configured in not shown patch bay device and the suture T of different in kind respectively.During the operation of beginning chain-type stitch, axle 18 is rotated, the connecting hole 27a of connecting elements 27 is connected with certain 1 conduit 24 that is placed with required suture T.Under this state, from the air supply source during, insert and lead in the through wires hole 11 of looper device R being placed on the suture T that utilize in the conduit of supplying with that air connected 24 to air supply part 28 air supplies, the end of a thread of suture T is derived from line export mouth 11b.And, but identical rotation when moving knife 33 being carried out cut off with line, with pass connecting hole 27a, the air supply part 28 of connecting elements 27 tube connector 30, looper device R through wires hole 11 and the suture T the end of a thread of deriving from line export mouth 11b is kept.
After the end of a thread maintenance with suture T, drive motor 14 makes looper device R rotation, and the crochet hook 4 of sewing machine head 3 is moved up and down.In addition, with these actions the framework 7 of making that is placed with tubular sewn object H is moved to the X/Y direction.Like this, can use required suture T, on sewn object H, carry out the chain-type stitch operation of style and embroidery etc.
When the suture T that carries out the chain-type stitch operation is switched, stop the rotation of looper device R and moving up and down of crochet hook 4, but then moving knife 33 is rotated successively to clockwise direction and counter clockwise direction, suture T is cut off.After suture T is cut off, but again that moving knife 33 is a certain amount of to the clockwise direction rotation, the maintenance of the end of a thread of the looper device R side of releasing suture T.Then, use not shown manual pulling off device will insert the suture T that leads in looper device R and pull out, make the end of a thread of the looper device R of the suture T that has removed above-mentioned maintenance be positioned at conduit 24.Axle 18 is rotated, the connecting hole 27a of connecting elements 27 is connected with the conduit 24 that is placed with the required suture T of next root,, suture T is inserted lead in looper device R to air supply part 28 air supplies, but rotate moving knife 33 then, keep inserting the end of a thread that leads to the suture T in looper device R.With aforementioned the same, make crochet hook 4 follow the rotation of looper device R and move up and down.Use required suture T that sewn object H is carried out the chain-type stitch operation.As everyone knows, the chain-type stitch form has chain type seam, circle chain-type stitch etc., and they switch according to the setting of making action.
As mentioned above, adopt the chain sitch sewing machine shown in the foregoing description, by conduit 24 with many lines be directed to looper device R near, member 27 can be connected the through wires hole 11 of each conduit 24 with looper device R by being rotationally connected, therefore can make the component volume that is positioned at looper device R below very little, looper base 5 can be made the narrow and small cartridge type of width.Can be located at the inboard of the sewn object H of multiple tubular thus.When switching suture T, because of only needing the connecting elements 27 of rotation small size,, and can carry out colour changing at a high speed so drive source can not only be made small-sizedly again.
In the foregoing description, to only supply with from the air of air supply source to air supply part 28, with slotting the leading in the through wires hole 11 of looper device R of suture T that is placed in the connected conduit 24, but be not limited to this, but near the also air supply rearward end of conductive pipe 24 is to help suture T mobile conduit 24 in.
In addition, with suture T be directed to looper device R near, selectively the threading opening of looper device R is connected with the end of conduit 24 by connecting elements 27, any the inserting of many sutures led in a looper device R, but more than this structure also not necessarily be positioned at the structure of tubular sewn object H inboard, that is, the utility model also goes for plane sewn object is carried out the Sewing machines of chain-type stitch.
In addition, suture T is directed to the configuration of a plurality of line supply ports of near the configuration of the conduit 24 the looper device R and carriage 20, being not limited to the axle center of axle 18 is the circular-arc configuration at center, for example also and row arrangement.This occasion, because of the connecting hole 27a with connecting elements 27 is connected with each conduit 24, thus of course not connecting elements 27 is rotated driving, but to its driving that walks abreast and move.
