Background technology
General traditional Sewing machines is one and connects a ground and become a string in succession by the suture that does not cut off as yet that wait to make and finish after the some, the sewings that one by one bunchiness is linked to each other is cut off with scissors one by one again when operation sewing workpiece.This operational method is cut off one by one owing to the operating personnel still must pick up scissors in addition again, so comparatively time-consuming consumption worker.
Please refer to TaiWan, China in disclosed No. 098204640 " Sewing machines cutting facility (one) " novel patent application on August 11st, 2009 and disclosed on the same day of the same month of the same year No. 098204637 " Sewing machines cutting facility (two) " novel patent application, this two patent application is the previous invention of the present application design that the people invents, different in order to add man-hour employed Sewing machines type in response to sewing because of function or label etc., look itself situation for the practitioner and select the required cutting facility of installing; Be above-mentioned two novel when using, need the end of a thread or the intact line tail of sewing are drawn in the cutting facility,, the end of a thread, line tail are separated with cloth, can't reach the automatic job pattern of consistentization like this to drive cutting facility afterwards again with the pedal post legged.
Given this, the inventor of the present application is promptly once more in line with this original intention, and research and development create another kind of structure and can reach automation, the industrial sewing machine automatic thread trimming device of more simplifying in the operation.
Summary of the invention
Main purpose of the present invention, provide a kind of industrial sewing machine automatic thread trimming device, can drive the trimming unit automatically, the end of a thread on the cloth sheet and line tail are cut off, and with the end of a thread and the line tail centralized collection cut, carry out the sewing operation of next clothing for the user, and this cutting facility has the characteristic that automation trimming function was simplified, assembles easily and reached to mode of operation.
For reaching above-mentioned purpose, industrial sewing machine automatic thread trimming device of the present invention is realized by following technical scheme:
Industrial sewing machine automatic thread trimming device of the present invention, be that side edge in the sewing platform of Sewing machines is provided with pedestal, on pedestal, establish trimming unit and positioning seat, has the guiding conduit on this positioning seat, and the guiding conduit is connected with external suction unit by joint, two sides in the guiding conduit are equiped with first detecting unit, in addition in the body of Sewing machines to should installing second detecting unit in sewing platform place, and above the corresponding guiding of the body conduit of Sewing machines, locate to be equiped with insufflation unit.
Useful technique effect of the present invention is: utilize second detecting element to detect cloth sheet position, and drive insufflation unit, trimming unit and suction unit in good time, guiding is cut off in the conduit and purt is drawn to suction unit so that the suture head on the cloth sheet is blown into, other utilizes first detecting unit to detect the sewer and whether the suture tail is pulled to the guiding conduit, to drive trimming unit and suction unit cutting suture tail and the suture purt is drawn to suction unit, to reach the usefulness of automated job.

The specific embodiment
Have more complete and clearly exposure for making technological means of the present invention, goal of the invention and reaching effect, preferred embodiment of the present invention is elaborated below in conjunction with accompanying drawing.
See also Fig. 1～Fig. 2, be the structural map of industrial sewing machine automatic thread trimming device of the present invention.This industrial sewing machine automatic thread trimming device is to establish a pedestal 2 in the side edge of the sewing platform 11 of Sewing machines 1, be provided with a trimming unit 3 and a positioning seat 4 in this pedestal 2, and on this positioning seat 4, put one and guide conduit 41, and make this guiding conduit 41 be connected with an external suction unit 5 by joint 42, two sides in this guiding conduit 41 are equiped with first detecting unit 6 again, and establish an enclosing cover 7 in the outboard cover of this positioning seat 4, in addition in the body of Sewing machines 1 to installing second detecting unit 8 in sewing platform 11 places, in the body of this Sewing machines 1 place, top that should guide channel road 41 is equiped with insufflation unit 9 again.
In view of the above, when desiring to carry out with in a tubular form the sewing operation of cloth sheet A sewing, referring to Fig. 1 and Fig. 3～Fig. 5, at first be to utilize this second detecting unit 8 to detect cloth sheet A position, sensed the cloth sheet A of seam feeding when this second detecting unit 8 after, just can notify this insufflation unit 9 in starting behind the preset time at interval, begin to blow, this is played the suture head B that knots of seam is blown in this this guiding conduit 41, at this moment, because of detecting, first detecting unit 6 have suture head B to pass through in this guiding conduit 41, cut off this suture head B so drive this trimming unit 3, this external suction unit 5 is also carrying out aspiratory action simultaneously, and the suture head B that will be cut off is drawn to extraneous centralized collection through these guiding conduit 41 purts.And when the user finishes the sewing operation of this cloth sheet A, referring to Fig. 1 and Fig. 6～Fig. 8, the user directly establishes the suture tail C drawing of connection to this guiding conduit 41 with Shang Yubu sheet A seam, make first detecting unit 6 of position detect suture tail C in these guiding conduit 41 both sides, and the control of the transmission by this message starts trimming unit 3 and carries out trimming and carry out the trimming action, cut off with suture tail C cloth sheet A end, this message also notifies this external suction unit 5 to begin to carry out aspiratory action simultaneously, consider the line of cutting off generation in the lump that purt is drawn to extraneous centralized collection to be worth doing, to reach the usefulness of automated job.
Wherein, above-mentioned this suction unit 5 begin to carry out air-breathing opportunity be this first detecting unit 6 detect have in this guiding conduit 41 suture head B, suture tail C by the time be activated (ginseng Fig. 1, Fig. 4, Fig. 7); Or promptly be under the suction condition of often opening after Sewing machines 1 start.
More than cited only be part embodiment of the present invention, be not in order to restriction the present invention, cause according to intention spirit of the present invention and feature, the modifications person of forming also should be included within this patent scope a little.
In sum, the embodiment of the invention really can reach desired use effect, its disclosed concrete structure again, not only be not seen in like product, also be not disclosed in application before, really meet the regulation and the requirement of Patent Law fully, the whence proposes the application of patent of invention in accordance with the law, earnestly ask and give examination, and grant quasi patent, then the true feeling moral just.
