Multi-needle bar module 2 of the present invention is prior art, comprises shank installing rack and is located at least two shanks spaced apart in shank installing rack.In the present embodiment, taking two shanks as example, switch accordingly cylinder of 4 need of air cylinder group.Certainly the present invention also can use three shanks or multi-needle bar more.
As shown in Figure 8, locating support 3 is connected with multi-needle bar module 2 by fixture 33 the preferred embodiments of the present invention.Two shanks in corresponding multi-needle bar module 2, locating support 3 has two crimpings, is respectively the first crimping 31 and the second crimping 32.Two drivers are installed on locating support 3, the drive rod of driver is connected with the wire pressing block that can coordinate crimping clamp simultaneously.
In the present embodiment, two drivers are the first driver 34 and the second driver 35.The drive rod of the first driver 34 is connected with the first wire pressing block 36.The drive rod of the second driver 35 is connected with the second wire pressing block 37.
Driver in the present invention can be cylinder, can be also electromagnet.In the present embodiment, the first driver 34 and the second driver 35 all adopt cylinder to realize the gripping action of wire pressing block.
The first wire pressing block 36 and the second wire pressing block 37 have respectively shaped as frame portion.The first crimping 31 and the second crimping 32 lay respectively in corresponding shaped as frame portion, and coordinate clamp with the inwall of corresponding shaped as frame portion.
Bracing wire cylinder 5 drives guy hook 51 rectilinear motions, and guy hook 51 can carry out hook line through shaped as frame portion.Guy hook 51 is retracted after being hooked to line, makes the end of a thread of holding suture through shaped as frame portion.The driver drives shaped as frame portion motion at operating position place, by coordinating suture clamped with crimping.
Sewing control system is existing sewing-machine control systems, comprise processor, mainboard, running memory, store memory, the input/output interface etc. of operational system and sewing process, can control the automation mechanized operation such as spindle motor rotation, the action of presser feet cylinder of Sewing machines by sewing control system.
Sewing control system of the present invention also has to control switches the first control module that air cylinder group 4 is worked, need to select the first shank to sew action time, the first control module can be exported control command to switching air cylinder group 4, make to switch air cylinder group 4 and drive the first shank to move to operating position place, corresponding the first crimping 31 and the first driver 34 also move to operating position place.Need to select the second shank to carry out sewing work time, the first control module can be exported control command and makes to switch air cylinder group 4 and drive the second shank to move to operating position place to switching air cylinder group 4.
Sewing control system also has the second control module of driver and the crimping loose ends of controlling operating position place before sewing starts.
Sewing control system also has in sewing initial 1 and keeps driver and the crimping clamp at operating position place during to 9 pin, and after initial 1 to 9 pin, makes the 3rd control module of driver and crimping loose ends sewing.
Sewing control system also has the 4th control module of controlling bracing wire cylinder 5 when sewing finishes and carry out bracing wire action and control driver in operating position carrying out clamp.
Now illustrate the course of work of multi-needle bar Sewing machines of the present invention.As shown in Figure 3, multi-needle bar Sewing machines of the present invention is before work, and the suture on the eedle of two shanks is all fixed by each self-corresponding crimping, eedle off-line while preventing from sewing withdrawal of needle.While carrying out sewing work, sewing control system, first according to program setting, moves to operating position place by the first control module by the first shank and corresponding the first crimping 31 and the first driver 34.According to program setting, before the spindle motor work of driving shank work, the second control module sends control command to the first driver 34, makes the first driver 34 and the first crimping 31 loose ends subsequently.The first eedle carries out sewing work under spindle motor drives.Now the end of a thread of the second eedle is still fixing by the second crimping 32, can prevent that the end of a thread of the first eedle and the second eedle is wound around.
When sewing finishes as shown in Figure 4, sewing control system, according to program setting, is carried out the trimming action of upper thread.Trimming simultaneously the 4th control module sends work order to the first driver 34 and bracing wire cylinder 5, and the drive rod of the first driver 34 stretches out, and makes guy hook 51 carry out hook line through the shaped as frame portion of the first wire pressing block 36; Guy hook 51 bounces back and makes the end of a thread pass the shaped as frame portion of the first wire pressing block 36 after holding the end of a thread of the first eedle, and the drive rod of the first driver 34 retraction, is fixed on the end of a thread on the first eedle on the first crimping 31 by the first wire pressing block 36 subsequently.
According to program setting, need to use the second shank to sew time, by the first control module, the second shank is moved to operating position place.As shown in Figure 5 and Figure 6, in sewing process, again repeat the second above-mentioned control module and the 4th control module.Sewing finishes as shown in Figure 7, and the end of a thread of the first eedle and the second eedle is separately fixed on corresponding crimping in order to carrying out sewing next time.
In sewing process, can also select the 3rd control module.While carrying out the 3rd control module, the shank of sewing control system testing position is in sewing withdrawal of needle 1 to 9 pin, the driver at operating position place and crimping retaining clip line states, after sewing withdrawal of needle 1 to 9 pin, the 3rd control module sends order to the driver at operating position place, controls driver and crimping loose ends.In specific embodiment, the 3rd control module preferably sets retaining clip line states in sewing withdrawal of needle 1 pin, 2 pins, 3 pins or 4 pins.For example the 3rd control module is set withdrawal of needle 2 pins, and while carrying out so the 3rd control module, in sewing withdrawal of needle 2 pins, the driver at operating position place and crimping be retaining clip line states all; Start driver and crimping loose ends at sewing the 3rd pin.
Carry out the 3rd control module and can in the time of each withdrawal of needle, control clamp state, can play the effect that prevents wire lead drop out, the tension force while simultaneously adjusting withdrawal of needle on suture, avoids fabric to occur a ball of string in sewing beginning.
Most preferred embodiment of the present invention is illustrated, and the various variations of being made by those of ordinary skill in the art or remodeling can not depart from the scope of the present invention.
