Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
Fig. 1 is to Figure 7 shows that structural representation of the present invention.
Reference numeral is wherein: feed lead rail 1, charging bearing 11, charging gear drive support 12, extension spring 13, charging motor 14, driving member 15, charging gear 2, material-handling rod 3, material folding cylinder 31, limiting plate 32, feeding clamping plate 4, feeding cylinder 41, cleat base 42, feeding clamping plate cylinder 43, feeding bottom plate 44, fervent cylinder 5, fervent resistance wire 51, resistance wire support 52, fervent support 53, material blocking rod 6, auxiliary stand 61, feeding base 7, mounting seat 71, adjustment bolt 72, rotary cylinder 8, sweeping through the material plate 81, mounting bracket 82, sewing machine head 9.
Ribbon processing method of the present invention, comprises the following steps: step 1, by ribbon roll up in ribbon input feed lead rail 1; Step 2, driving ribbon export to the outlet of feed lead rail 1 length set; When step 3, ribbon export to outlet, by the ribbon end of material-handling rod 3 stationary exit; Step 4, ribbon continue export to outlet and form ribbon ring outside outlet, clamp ribbon ring by feeding clamping plate 4; Step 5, the ribbon ring cut outside outlet; Step 6, by feeding cylinder 41, to be sewed in the sewing area that the ribbon ring on feeding clamping plate 4 moves to sewing mechanism.
Apply the inkle loom of above-mentioned ribbon processing method, comprise sewing mechanism and feeding mechanism, sewing mechanism can adopt known sewing machine head 9.
Feeding mechanism has for the charging gear 2 carrying the feed lead rail 1 of ribbon and drive ribbon to move along feed lead rail 1.In the present embodiment, feed lead rail 1 is made up of two pieces of feedboards, and ribbon passes through between the sidewall of two pieces of feedboards.The mounting distance of adjustment two pieces of feedboards, just can adjust the width of feed lead rail 1, adapts to the ribbon of different size.
The two pieces of feedboards forming feed lead rail 1 are fixed on charging bearing 11.Charging bearing 11 is provided with the charging gear drive support 12 that can rotate.One end of charging gear drive support 12 is rotationally connected by rotating shaft and charging bearing 11, and another movable end is connected with charging bearing 11 by extension spring 13.Charging gear 2 is rotated by bearing and is located on charging gear drive support 12, and is connected by the power output shaft of driving member 15 with charging motor 14.Driving member 15 can be chain or Timing Belt.Charging motor 14 can be stepper motor, also can be servomotor, controls the length of carrying ribbon by the rotational travel controlling charging motor 14.
As shown in Fig. 2 to 5, inkle loom also has fixes the material-handling rod 3 of ribbon end, the material cutting mechanism cut off by exit ribbon and the feeding clamping plate 4 being positioned at exit in the outlet of feed lead rail 1.Material-handling rod 3 is driven by material folding cylinder 31, by ribbon end winding support on charging bearing 11 or on auxiliary member.Material-handling rod 3, except being driven by material folding cylinder 31, also can adopt motor drive mode.
In this practical example, the auxiliary member coordinating material-handling rod 3 material folding is the material blocking rod 6 being arranged on exit.Material blocking rod 6 is fixed on charging bearing 11 by auxiliary stand 61.Material folding cylinder 31 drives material-handling rod 3 by ribbon end winding support between material-handling rod 3 and material blocking rod 6.
The stroke that charging motor 14 can be rotated by control system setting.When control system sends feed command to charging motor 14, the length that the ribbon in feed lead rail 1 sets to exit movement under charging gear 2 conveying.Control system controls material folding cylinder 31 according to the movement travel of charging motor 14 and carries out material folding.When ribbon exports a bit of to outlet, the ribbon end that material folding cylinder 31 just drives the fixing output of material-handling rod 3 to export, ribbon continues to export to outlet, just outside exporting, forms a ribbon ring.
Feeding clamping plate 4 are provided with in the outlet side of feed lead rail 1.This ribbon ring of feeding clamping plate 4 gripping, and after material cutting mechanism cuts ribbon ring, by feeding cylinder 41, the ribbon ring on feeding clamping plate 4 is moved to the sewing area of sewing mechanism.
After material cutting mechanism cuts ribbon ring, material folding cylinder 31 drives material-handling rod 3 to rise.Charging motor 14 can again to the ribbon of outlet conveying preseting length, material folding cylinder 31 is according to the conveying process of charging motor 14, automatic driving material-handling rod 3 declines with the ribbon end outside stationary exit, and ribbon continues conveying just at the next ribbon ring of the outer formation of outlet.Inkle loom repeats the above-mentioned course of work, greatly can improve the efficiency that ribbon is folded into ribbon ring.
Limiting plate 32 can be provided with above the outlet of feed lead rail 1.Ribbon ring is when exporting outer formation, and the top of ribbon ring is subject to limiting plate 32 and limits, and the ribbon ring of formation can be made to have intrinsic shape to a certain degree, be convenient to feeding clamping plate 4 gripping ribbon ring.
In the present embodiment, material-handling rod 3 is fixedly connected with the drive rod of material folding cylinder 31 respectively with limiting plate 32, drives material-handling rod 3 and limiting plate 32 rise simultaneously or decline by material folding cylinder 31.When material-handling rod 3 and limiting plate 32 decline, material-handling rod 3 clamps ribbon end, and limiting plate 32 is also in operating position simultaneously.
As shown in Figure 6, the drive rod of feeding cylinder 41 is connected with cleat base 42, is positioned at ribbon ring side when cleat base 42 is initial.Cleat base 42 is fixed with feeding clamping plate cylinder 43 and feeding bottom plate 44.The drive rod of feeding clamping plate cylinder 43 is connected with feeding clamping plate 4, and feeding clamping plate 4 can be driven to move to clamp material to feeding bottom plate 44.After ribbon ring is folded, feeding clamping plate cylinder 43 drives feeding clamping plate 4 to clamp ribbon ring, and then feeding cylinder 41 drives cleat base 42 to move, and ribbon ring is moved to sewing region.
In the present embodiment, the fervent resistance wire 51 that material cutting mechanism comprises fervent cylinder 5 and driven by fervent cylinder 5.Fervent resistance wire 51 is arranged on resistance wire support 52, and is connected with power supply.Resistance wire support 52 is connected by the drive rod of fervent support 53 with fervent cylinder 5.When wanting blank, by fervent cylinder 5 drive fervent resistance wire 51 decline contact exit ribbon to cut ribbon ring.
Material cutting mechanism also can adopt cutting knife air cylinder driven cutting knife to cut ribbon ring outside outlet.
In the present embodiment, charging bearing 11, material folding cylinder 31 and fervent cylinder 5 are separately fixed on feeding base 7.Feeding base 7 is slidably arranged on the guide rail of mounting seat 71, and fixedly mounts position by adjustment bolt 72.
As shown in Figure 7, mounting seat 71 is fixed with rotary cylinder 8 by mounting bracket 82, and the rotary actuation bar of rotary cylinder 8 is connected with sweeping through the material plate 81.Sweeping through the material plate 81 is positioned at above the needle plate of sewing machine head 9, and after ribbon circumferential weld has been threaded, rotary cylinder 8 drives sweeping through the material plate 81 to move, and the ribbon ring of sewing it up is swept the needle plate from sewing machine head 9.
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.
