Multi-needle bar module 2 of the present invention is prior art, comprises shank installing rack and to be located in shank installing rack at least two shanks spaced apart.In the present embodiment, for two shanks, corresponding switching air cylinder group 4 need cylinder.Certain the present invention also can use three shanks or more shank.
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.On locating support 3, be provided with two drivers, 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, also can be 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.
First wire pressing block 36 and the second wire pressing block 37 have shaped as frame portion respectively.First crimping 31 and the second crimping 32 lay respectively in corresponding shaped as frame portion, and coordinate clamp with the inwall in corresponding shaped as frame portion.
Bracing wire cylinder 5 drives guy hook 51 rectilinear motion, 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 pulling suture through shaped as frame portion.The driver drives shaped as frame portion motion at operating position place, clamps suture by coordinating with crimping.
Sewing control system is existing sewing-machine control systems, comprise processor, mainboard, running memory, the memory storing operational system and sewing process, input/output interface etc., the automation mechanized operation such as spindle motor rotation, the action of presser feet cylinder of Sewing machines can be controlled by sewing control system.
Sewing control system of the present invention also has the first control module controlling to switch air cylinder group 4 work, when needing selection first shank to carry out sewing action, first control module can export control command to switching air cylinder group 4, make switching air cylinder group 4 drive the first shank to move to operating position place, corresponding first crimping 31 and the first driver 34 also move to operating position place.When needing selection second shank to carry out sewing work, the first control module can export control command to switching air cylinder group 4 makes switching air cylinder group 4 drive the second shank to move to operating position place.
Sewing control system also have sewing start before control the driver at operating position place and the second control module of crimping loose ends.
Sewing control system also has the driver and the crimping clamp that keep operating position place when sewing initial 1 to 9 pin, and makes the 3rd control module of driver and crimping loose ends after initial 1 to 9 pin of sewing.
Control bracing wire cylinder 5 at the end of sewing control system also has sewing and carry out bracing wire action and the driver controlling to be in operating position carries out the 4th control module of 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 when preventing from sewing withdrawal of needle.When carrying out sewing work, the first crimping 31 of the first shank and correspondence and the first driver 34, first according to program setting, are moved to operating position place by the first control module by sewing control system.Subsequently according to program setting, before the spindle motor work 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.First eedle carries out sewing work under spindle motor drives.Now the end of a thread of the second eedle is still fixed by the second crimping 32, and the end of a thread of the first eedle and the second eedle can be prevented to be wound around.
As shown in Figure 4 at the end of sewing, sewing control system, according to program setting, performs 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 can carry out hook line through the shaped as frame portion of the first wire pressing block 36; Guy hook 51 bounces back after holding the end of a thread of the first eedle and makes the end of a thread pass the shaped as frame portion of the first wire pressing block 36, and the drive rod retraction of the first driver 34, 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, when needing use second shank to sew, 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 terminates 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.
The 3rd control module can also be selected in sewing process.When performing 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, 3rd control module sends order, control and drive system and crimping loose ends to the driver at operating position place.In a particular 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.Such as the 3rd control module setting withdrawal of needle 2 pin, when so performing the 3rd control module, in sewing withdrawal of needle 2 pin, the driver at operating position place and crimping be retaining clip line states all; Driver and crimping loose ends is started at sewing the 3rd pin.
Perform the 3rd control module and can control clamp state when each withdrawal of needle, the effect preventing wire lead drop out can be played, the tension force simultaneously during adjustment withdrawal of needle on suture, avoid fabric to occur a ball of string in sewing beginning.
Most preferred embodiment of the present invention is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from the scope of the present invention.
