As depicted in figs. 1 and 2, the present invention meets the seam mechanism in cloth method, comprises frame 1 and for the overseam head 2 connected of being sewed at two pieces of cloth edges.Frame 1 has one for what place cloth to be connected and puts flitch 11.Frame 1 is slided be provided with at least three energy near or away from the cloth fixing device putting flitch 11, each cloth fixing device correspondence is provided with one for responding to overseam head 2 position and controlling cloth fixing device relative to 11 inductors 31 slided of putting flitch.
As shown in Figure 3, frame 1 has the first presser feet 13 of being fixed on and putting flitch 11 one end and can along the second presser feet 14 put flitch 11 and slide.
First presser feet 13 is connected with the presser feet rotating shaft on the first presser feet seat 13b, can around presser feet axis of rotation binder or loose metal.First presser feet cylinder 13a is connected with the first presser feet 13 by attaching parts, drives its binder.
In a preferred embodiment, in order to can easily binder, and after sewing completes, avoid cloth to be hooked by the first presser feet 13, the first presser feet 13 also can slide relative to frame 1.First presser feet seat 13b can be slidably arranged in frame 1 by the first presser feet guide rail 13c, and drives the first presser feet seat 13b to slide along the first presser feet guide rail 13c by the first presser feet sliding cylinder 13d.
Frame 1 is provided with the second guide rail 15, and slip is provided with the second presser feet seat 16.Frame 1 is provided with the second presser feet motor 17 that driving second presser feet seat 16 slides along the second guide rail 15.Second presser feet 14 is arranged on the second presser feet seat 16, and the second presser feet seat 16 is provided with the second presser feet cylinder 18 of driving second presser feet 14 binder.
Be placed into after the tail end of piece of cloth material aligns with the head end of another block cloth and put on flitch 11 and cloth fixing device.First presser feet sliding cylinder 13d drives the first presser feet seat 13b to move to material folding position, then drives the first presser feet 13 to push down the side of two blocks of clothes by the first presser feet cylinder 13a.Second presser feet motor 17 drives the second presser feet seat 16 to slide into the roughly midway location putting flitch 11, second presser feet cylinder 18 drives the second presser feet 14 to push down cloth, drive the second presser feet seat 16 to slide to cloth opposite side by the second presser feet motor 17 again, cloth is shakeout putting on flitch 11.
In the present embodiment, frame 1 is fixed with two the second presser feet synchronous wheel seat 17a, two the second presser feet synchronous wheel seat 17a are separately installed with presser feet synchronizing wheel 17b, and be equipped with presser feet Timing Belt 17c between two presser feet synchronizing wheel 17b, the second presser feet seat 16 is connected with presser feet Timing Belt 17c.Second presser feet motor 17 is fixedly mounted on one of them second presser feet synchronous wheel seat 17a, and the power take-off shaft of the second presser feet motor 17 is connected with corresponding presser feet synchronizing wheel 17b, the second presser feet seat 16 is driven to slide along the second guide rail 15 by presser feet Timing Belt 17c.
Overseam head 2 can slide relative to frame 1.The end of two blocks of clothes is after putting flitch 11 and cloth fixing device shakeout, and overseam head 2 to slide from the side of cloth to the opposite side of cloth sew along putting flitch 11.
As shown in Figure 4 and Figure 5, frame 1 is slided the erecting frame 21 be provided with for installing overseam head 2, and drives erecting frame 21 to slide by drive motor 22.
Frame 1 is installed with the head rail 12 with cloth sides aligned parallel, and erecting frame 21 is fixed on the slide block of head rail 12.In a preferred embodiment, drive motor 22 is fixed on erecting frame 21, and the power take-off shaft of drive motor 22 is fixed with driven wheel 22a, and this driven wheel 22a is meshed with the tooth bar 22b in frame 1.By controlling the rotation of drive motor 22, erecting frame 21 is slided along head rail 12, overseam head 2 is transported to another side from cloth, and in the sliding process of overseam head 2, the sewing completing cloth edge connects.
In other embodiments, drive motor 22 also can be fixed in frame 1.The power take-off shaft of drive motor 22 drives Timing Belt to rotate, then is slided along head rail 12 by Timing Belt drive installation frame 21.
As shown in Figure 6 to 8, in the present embodiment, cloth fixing device has 6, along putting the arrangement of flitch 11 side.Each cloth fixing device comprises a box body 3 be slidably mounted in frame 1.Box body 3 is provided with the suction plate 34 of band wind inlet, and the inner chamber of box body 3 is connected with tracheae 36 by aspirate tube interface 35.
In order to strengthen the fixation of cloth fixing device to cloth edge further, the holding pad 37 that can rotate can be installed on box body 3 and drive holding pad 37 to rotate the binder cylinder 38 of binder.
Frame 1 is fixed with the first guide rail 32.Box body 3 is fixed on the first slide block of the first guide rail 32, slides along the first guide rail 32.
Frame 1 is connected with the first cylinder 33 for driving box body 3 to slide, by the first cylinder 33 drive box body 3 near or away from putting flitch 11.Each first cylinder 33 controls work by the inductor 31 of correspondence.Inductor 31 also can be touching switch, and when overseam head 2 encounters touching switch, inductor 31 controls the first corresponding cylinder 33 and works, and makes box body 3 away from putting flitch 11, so that overseam head 2 continues to sew along putting flitch 11 slip.
Inductor 31 also can be the sensor detecting overseam head 2 position, when overseam head 2 slides, sends signal after corresponding sensor detects to control system, and control system controls corresponding first cylinder 33 and works.
Holding pad 37 is connected with box body 3 by rotating shaft.The piston rod of binder cylinder 38 matches with drive block, to drive holding pad 37 binder or loose metal around the shaft.
Erecting frame 21 is installed with and the stock guide 25 of the needle plate of overseam head 2 in same level, and stock guide 25 is being put between flitch 11 and suction plate 34.Guide roller 26 can also be provided with on the surface of stock guide 25.
Erecting frame 21 is also fixed with backgauge frame 23, and backgauge frame 23 has the striker plate 24 being positioned at and putting and also can be elevated above flitch 11.
The inductor 31 that each cloth fixing device is corresponding is arranged in frame 1 along overseam head 2 direction of slip interval.During work, the end overlap of two blocks of clothes is placed into puts on flitch 11 and cloth fixing device and after shakeouing, cloth fixing device adsorbs cloth by holding pad 37 binder and suction plate 34.
Drive motor 22 drives overseam head 2 to start to slide, first touch with first inductor 31 near start end, make first corresponding cloth fixing device away from putting flitch 11, at first cloth fixing device and put the passage forming overseam head 2 between flitch 11 and slide.
Overseam head 2 is at first cloth fixing device and put and continue to move between flitch 11 and carry out sewing operation.Sewed cloth first paragraph edge after, overseam head 2 is sewed and mobile is touched second inductor 31, and making second cloth fixing device away from putting flitch 11, sews in overseam head 2 pairs of second segment cloth edges.So, each cloth fixing device, under inductor 31 controls, can keep the planarization of cloth, can not interfere again the sewing activity of overseam head 2 when sewing.
In order to better fix cloth when overseam head 2 slides sewing, keeping the planarization of cloth, putting flitch 11 and can also be shaped with wind inlet.Be provided with the cavity 11a that bleeds be connected with tracheae 36 in the bottom of putting flitch 11, the cavity 11a that bleeds has the aperture communicated with wind inlet, and tracheae 36 produces suction, cloth is adsorbed on and puts on flitch 11.When overseam head 2 starts to sew, cloth both sides are fixed by the first presser feet 13 and the second presser feet 14, and the middle part of cloth is adsorbed on and puts on flitch 11 simultaneously, effectively prevents cloth from rolling.
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.
