Line L lower section, thread L to be cut off is hooked using hook-shaped blade 41.It is preferred that wherein before cut-out thread L, control
The outlet salad 23 of the control of device 10 edge-pulling machine processed clamps thread L stopping outlets and (mainly uses the air pressure in outlet salad 23
Cylinder 232 drives two salad pieces 231 to clamp thread L), it can so cause thread L to be cut off to be maintained at nervous shape
Under state, then, the action that tangential knife 40 is returned to normality standby position can be cut off by thread L by driver 30.
Illustrate the continuous action of the automatic tangent apparatus for the edge-pulling machine that this creation is proposed below by way of Fig. 3 A- Fig. 3 G, in order to
Readily appreciate and eccentric swage P, feed appliance are not illustrated in the action of needle bar 21 and crochet hook 22, figure, and only show outlet salad 23
Members.
(1) as shown in Fig. 3 A, before sewing operation is started (edge-pulling machine now is halted state), it is installed on needle bar
The needle bar 21 of seat 24 is in the position of starting point, and wherein thread L reaches pin after by outlet salad 23 by needle bar seat 24
Rod 21, thread L the end of a thread passes through the pin hole of needle bar 21 and retains the end of a thread of sufficient length in needle bar 21, treats the sewing of sewing
Object 70 also reaches the precalculated position of feed appliance.At the same time, the tangential knife 40 of the utility model automatic tangent apparatus is parked in often
The standby position of state (see Fig. 4 A).
(2) as shown in Fig. 3 B, sewing operation is proceeded by, needle bar 21 is positioned against sewing object 70 from starting point
Direction is advanced (going out needle movement), and now the two of outlet salad 23 salad piece 231 keeps the state loosened not clamp thread
L, needle bar 21 pierces through sewing object 70, and one section of thread L is brought to the outside of sewing object 70 by needle bar 21 and (shown in Fig. 3 B
The right side of sewing object 70).
(3) as shown in Fig. 3 C, (narrowing fortune during needle bar 21 is retracted towards the direction of the inner side of sewing object 70
It is dynamic), one section of thread L in the foregoing outside positioned at sewing object 70 initially forms coil L1, and at this moment, crochet hook 21 extends sewing
The outside of object 70 and hook described coil L1 (please also refer to Fig. 4 B).
(4) as shown in Fig. 3 D, needle bar 21 carries out narrowing motion and has been retracted to towards the direction of the inner side of sewing object 70
The position of initial point, then crochet hook 22 cross the apical margin of sewing object 70 and be moved to the inner side of sewing object 70, crochet hook 22 is drawn simultaneously
The apical margin of the coil L1 from the sewing object 70 that are firmly hooked is crossed, subsequently into the inner side (top of sewing object of sewing object 70
Edge is still pushed down by eccentric swage, is not illustrated in figure), feed mechanism can also drive sewing object 70 to move (in such as Fig. 3 D at the same time
The signified direction of arrow 50), when going out needle movement of needle bar 21 is slightly below in the position of the crochet hook 22 of the inner side of sewing object 70
Horizontal level.
(5) as shown in Fig. 3 E, needle bar 21 makes needle movement again, and now needle bar 21 initially passes through foregoing with thread L
Arrival sewing object 70 inner side coil L1 (please also refer to Fig. 4 C).
(6) as shown in Fig. 3 F, then needle bar 21 pierces through sewing object 70, then by needle bar 21 is had already passed through one section foregoing
Coil L1 thread L is brought to the outside of sewing object 70.
(7) as shown in Fig. 3 G, needle bar 21 carries out narrowing campaign again, and the action as shown by earlier figures 3C is located at
One section of thread L in the outside of sewing object 70 forms new coil L2 again, is then cyclically repeated earlier figures 3C- Fig. 3 G's
Action, can just form continuous sewing tissue in sewing object 70 (see Fig. 5 A).
After sewing operation is completed, operator starts controller 10 and carries out thread cutting action, the such as, but not limited to company of pressing
The tangent line button 11 of controller 10 is connect, controller 10 can determine the dynamic of tangent mechanism according to the position of foregoing needle bar 21, crochet hook 22
Make time point progress thread cutting action, one of which embodiment can install microswitch (micro in the drive mechanism of edge-pulling machine
Switch), microswitch is triggered when needle bar 21, crochet hook 22 reach default position under the drive of drive mechanism and produces tangent line
Signal, controller 10 can just be operated according to the driver 30 of tangent line signal control tangent mechanism, and then complete thread cutting action.It please join
Fig. 5 A are read, in the actuation time point of the progress thread cutting action, wherein needle bar 21, which has completed to narrow, moves back into the position of starting point
Put, and the apical margin that crochet hook 22 is then coil L1 from sewing object 70 that pulling is hooked is crossed, subsequently into sewing object 70
Inner side (with earlier figures 3D identicals position), the driver 30 of tangent mechanism first promotes tangential knife 40 with an oblique angle obliquely court
Stretched out to the direction of hook line position (see Fig. 5 C), when tangential knife 40 reaches hook line position, the root edge of tangential knife 40 can be pressed in close
The thread L of the front end of needle bar 21 top (see Fig. 5 A), then the blade 41 of tangential knife 40 can reach thread L to be cut off
Lower section, thread L, the thread L to be cut off hooked by blade 41 to be cut off is hooked using hook-shaped blade 41
It is the part line segment for having formed the coil L1, in other words, tangential knife 40 constitutes coil L1 thread L to cut off.Preferably
Ground, wherein before cut-out thread L is performed, the outlet salad 23 of the control edge-pulling machine of controller 10 clamps thread L and stops
Line, can so cause thread L to be cut off to be maintained in the state of anxiety, then, by driver 30 by tangential knife 40
The action of normality standby position is returned to regard to thread L can be cut off, the cut-out point position that its coil L1 is cut off by tangential knife 40
The 60 needle point remote position apart from needle bar 21 in coil L1 is preferred (see Fig. 5 B- Fig. 5 C), and thread L is being cut off
Afterwards, operator by sewing object 70 from the feed mechanism of edge-pulling machine remove when, cut-out thread L before formed coil L1's
One section of thread L major part still can stay in needle bar 21, and the end of a thread of consistent and sufficient length can be retained in needle bar 21, it is not necessary to
Threading can just carry out next sewing task immediately again.
In fact, extending out to hook line position from tangential knife 40 and then being retracted to the whole thread cutting action of normality standby position
Time is very short, is usually no more than 1 second, it will be apparent that cut thread L mode faster manually than tradition.This practicality
It is new to solve existing edge-pulling machine trimming is so that the problem of low production capacity in a manual manner, while after cut-out thread,
The end of a thread of consistent and sufficient length can be retained in needle bar, it is not necessary to which threading can just carry out next sewing task immediately again.
Although the utility model is disclosed as above by the above embodiments, so it is not limited to the utility model,
Those skilled in the art, are not departing from spirit and scope of the present utility model, when can make a little change and retouching, therefore this
The scope of patent protection of utility model must be defined depending on the claims hereof person of defining.
