Background technology
orderbefore stitching general on the market connect cloth equipment, function, structure are simple, can deal with the not high producer of ask for something and complete and general connect cloth sewing requirement.But along with continuing to bring out of various material and new technology, new technical matters and function characteristics also emerge in an endless stream.Above-mentioned stitching connects cloth equipment and runs into some special materials, and especially multilayer material is sewed up simultaneously, and thickness is too thick; The too fast grade of stitching speed requires that higher technological requirement is just helpless, can not complete diversified technological requirement, reach customer requirement.
The limitation that cloth equipment can not complete diversified technological requirement is connect for overcoming general stitching, the utility model uses control theory and the control method of modern mature and reliable on the basis of above-mentioned machine, adopt Japanese herd-boy's Sewing machines, PLC programming Control, the methods such as electric eye detection make machine both can complete general technology, also the requirement of some special process can be completed, the materials such as such as nonwoven fabric, plastic woven cloth, paper-plastic stick are sewed up, accomplish that mechanical movement is steady, non-jitter, stitching speed is high, and suture location is firm, attractive in appearance, not easily break.
Summary of the invention
For achieving the above object, the utility model adopts following technical scheme one to sew up and connects cloth equipment, mainly comprise: connect by two pieces, left and right frame, automatic sewing device, clamping device that cloth wallboard forms and unreel checkout gear, described unreels charging place that checkout gear is arranged on frame, described frame top is provided with clamping device and automatic sewing device, and machine frame inside arranges and connects cloth push rod, traction clamping and conveying device and the tenslator for controlling material tension.
Further, described automatic sewing device is provided with the infrared ray electric eye for test material, and the automatic sewing device controlled by PLC is arranged on the line slideway of frame top.
Further, described guide rail adopts two Guide Rail Design, and the chain controlled by PLC drives automatic sewing device left and right transverse shifting on line slideway.
Further, the described cloth push rod that connects controls push rod lifting by longitudinal cylinder of both sides.
Further, the described cloth push rod both sides that connect are equipped with two groups of clamping devices for fastening material both sides respectively, and the pneumatic cylinder that clamping device is distributed by two mirror images and push rod form.
Further, connect cloth push rod and be at least provided with the round and smooth push rod in a top.
Further, described tenslator controls by cylinder the tension force that jockey pulley carrys out compensative material.
Further, described traction clamping and conveying device controls the gap between rubber roller and traction steel rod by adjustable pressure cylinder.
The utility model has the advantage of:
1, automatic sewing device is at line slideway left and right transverse walking function, and by PLC control, frequency control and band infrared ray electric eye motion detection, thus improve automaticity, working stability, greatly reduces man power and material.
2, strain oscillatory device controls to unreel the tension stability connect between cloth, and Synchronization Control guarantees that material is wrinkle resistant, does not break, and improves the class of machine, has widened the applicability of machine;
3, connect the cylinder action of cloth push rod and selvedge clamping device employing PLC control, automaticity is high, while guaranteeing the degree of accuracy, takes into account mechanical action smoothness, coordinates automatic sewing device to sew up material well.

detailed description of the invention:
With reference to Fig. 1 ~ 4, a kind of stitching connects cloth equipment, mainly comprise: connect by two pieces, left and right the frame 1 that cloth wallboard 11 forms, automatic sewing device 2, clamping device 5 and unreel checkout gear 7, described unreels charging place that checkout gear 7 is arranged on frame 1, unreel checkout gear 7 carry out the diameter of test material by ultrasonic instrument and calculate surplus, thus reminding employees unreels material, described frame 1 top is provided with clamping device 5 and automatic sewing device 2, frame 1 inside arranges and connects cloth push rod 6, traction clamping and conveying device 3 and the tenslator 4 for controlling material tension, compare and sew with tradition, sew up the mechanical structure connecing cloth equipment and adopt PLC to control, not only guarantee mechanical movement fluency, and sew up firmly and positional accuracy in guarantee.
Described automatic sewing device 2 is provided with the infrared ray electric eye 21 for test material, the automatic sewing device 2 controlled by PLC is arranged on the line slideway 22 at frame 1 top, described guide rail 22 adopts two Guide Rail Design, the chain controlled by PLC drives automatic sewing device 2 left and right transverse shifting on line slideway 22, infrared ray electric eye 21 can detect sewing position accurately and whether accompany material, send signal again to controller, the knitting wool of automatic sewing device 2 is avoided to make a mistake intertexture, automatic sewing device 2 is caused to occur from card phenomenon in running, the operation of impact machinery.
The described cloth push rod 6 that connects controls push rod 62 by longitudinal cylinder 61 of both sides and is elevated and coordinates automatic sewing device 2, the described cloth push rod 6 that connects at least is provided with the round and smooth push rod 62 in a top, to avoid in the process of material jack-up causing damage to material, it connects cloth push rod 6 both sides and two groups of clamping devices 5 for fastening material both sides is housed respectively, the pneumatic cylinder that clamping device 5 is distributed by two mirror images and push rod form, by liftable many push rods 62 by material upwards jack-up, again by clamping device 5 fastening material on both sides, many push rods 62 will return original position.
Described tenslator 4 controls by cylinder 41 tension force that jockey pulley 42 carrys out compensative material, major control unreels the tension stability connect between cloth apparatus, described traction clamping and conveying device 3 controls the gap between rubber roller 32 and traction steel rod 31 by adjustable pressure cylinder 33, connects in cloth process provide traction power in the conveying of material.
During work, unreel checkout gear 7 carry out the diameter of test material by ultrasonic instrument and calculate surplus, and reminding employees puts into another roll of material, make leading portion material and back segment material staggered superposition, materials at two layers transmits and enters frame 1 inside under the effect of traction clamping and conveying device 3, when superposition place of materials at two layers is sent to and connects above cloth push rod 6, stop traction clamping and conveying device 3 and start longitudinal cylinder 61 push rod 62 round and smooth for many tops is upwards pushed, drive superposition place of material to rise simultaneously.Clamping device 5 is by the both sides of pneumatic cylinder fastening material, many push rods 62 will return original position, when the infrared ray electric eye 21 of automatic sewing device 2 detects material, chain drives automatic sewing device 2 to laterally move on line slideway 22, starts to sew up superposition place of material.When sewing up complete, automatic sewing device 2 returns original position automatically.Traction clamping and conveying device 3 is restarted while clamping device 5 unclamps.
Certainly, these are only the utility model better embodiment, not limit the scope of application of the present utility model with this, therefore, every make in the utility model principle equivalence change all should be included in protection domain of the present utility model.
