As depicted in figs. 1 and 2, the present invention connects cloth machine, including frame 1 with for the overseam head 2 connected of being sewed at two pieces of cloth edges.Frame 1 has one and puts flitch 11 for what place cloth to be connected.In frame 1 slide be provided with at least three can closer or far from the cloth fixing device putting flitch 11, each cloth fixing device correspondence be provided with one for sense overseam head 2 position and control cloth fixing device relative to put flitch 11 slide induction apparatuss 31.
It is fixed on the first presser feet 13 putting flitch 11 one end as it is shown on figure 3, frame 1 has and the second presser feet 14 that flitch 11 slides can be put in edge.
First presser feet 13 is connected with the presser feet rotating shaft on the first presser feet seat 13b, it is possible to around presser feet axis of rotation binder or loose metal.First presser feet cylinder 13a is connected by connector and the first presser feet 13, drives its binder.
In a preferred embodiment, in order to can easily binder, and avoid cloth to be hooked by the first presser feet 13 after sewing completes, the first presser feet 13 can also 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 driving the second presser feet seat 16 to slide 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 driving the second presser feet 14 binder.
The tail end of cloth is placed into after aliging with the head end of another cloth and puts 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 is driven 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 approximately mid way between putting flitch 11, second presser feet cylinder 18 drives the second presser feet 14 to push down cloth, driven the second presser feet seat 16 to slide to cloth opposite side by the second presser feet motor 17 again, make cloth flitch 11 shakeout putting.
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, are equipped with presser feet Timing Belt 17c between two presser feet synchronizing wheel 17b, and 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 output 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 and shakeouing on flitch 11 and cloth fixing device, and overseam head 2 slides from the side of cloth to the opposite side of cloth and sews along putting flitch 11.
As shown in Figure 4 and Figure 5, frame 1 slip is provided with the installing rack 21 for installing overseam head 2, and drives installing rack 21 to slide by drive motor 22.
Being installed with the head rail 12 with cloth sides aligned parallel in frame 1, installing rack 21 is fixed on the slide block of head rail 12.In a preferred embodiment, drive motor 22 is fixed on installing rack 21, and the power output shaft of drive motor 22 is fixed with driving gear 22a, and this driving gear 22a is meshed with the tooth bar 22b in frame 1.By controlling the rotation of drive motor 22, making installing rack 21 slide along head rail 12, from cloth, overseam head 2 is transported to another side, in the sliding process of overseam head 2, the sewing completing cloth edge connects.
In other embodiments, drive motor 22 can also be fixed in frame 1.The power output 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 includes a box body being slidably mounted in frame 13.Box body 3 is provided with the suction plate 34 of wind inlet, and the inner chamber of box body 3 is connected with trachea 36 by suction nozzle interface 35.
In order to further enhance the cloth fixing device fixation to cloth edge, it is possible to install the holding pad 37 that can rotate on box body 3 and driving pressure flitch 37 rotates 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 to the first cylinder 33 for driving box body 3 to slide, and drives box body 3 closer or far from putting flitch 11 by the first cylinder 33.Each first cylinder 33 is controlled work by corresponding induction apparatus 31.Induction apparatus 31 can also be touching switch, and when overseam head 2 encounters touching switch, induction apparatus 31 controls the first cylinder 33 of correspondence and works, and makes box body 3 away from putting flitch 11, in order to overseam head 2 continuation is sewed along putting flitch 11 slip.
Induction apparatus 31 can also be the sensor of detection overseam head 2 position, and when overseam head 2 slides, corresponding sensor sends signal to control system after detecting, 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 around the shaft or loose metal.
Installing rack 21 is installed with the stock guide 25 in same level of the needle plate with overseam head 2, and stock guide 25 is being put between flitch 11 and suction plate 34.It is also provided with guide roller 26 on the surface of stock guide 25.
Installing rack 21 is further fixed on backgauge frame 23, and backgauge frame 23 has to be positioned at puts the striker plate 24 that also can lift above flitch 11.
The induction apparatus 31 that each cloth fixing device is corresponding is arranged in frame 1 along overseam head 2 glide direction interval.During work, the end overlap of two blocks of clothes is placed into after putting on flitch 11 and cloth fixing device and shakeouing, and 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 induction apparatus 31 near start end, make correspondence first cloth fixing device away from putting flitch 11, first cloth fixing device and put between flitch 11 formed overseam head 2 slide passage.
Overseam head 2 is at first cloth fixing device and puts and continues to move between flitch 11 and carry out sewing operation.Having sewed behind the first paragraph edge of cloth, overseam head 2 sewing is mobile touches second induction apparatus 31, makes second cloth fixing device away from putting flitch 11, is sewed in second segment cloth edge by overseam head 2.So, each cloth fixing device, under induction apparatus 31 controls, can keep the planarization of cloth, will not interfere with again the sewing activity of overseam head 2 when sewing.
In order to better fix cloth when overseam head 2 slides sewing, keep the planarization of cloth, put flitch 11 and can also be shaped with wind inlet.Be provided with the cavity 11a that bleeds being connected with trachea 36 in the bottom putting flitch 11, the cavity 11a that bleeds has the aperture communicated with wind inlet, and trachea 36 produces suction, makes cloth be 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.
