bar driver 85 is a cylinder device coupled to the adjustingbar supporter 83 and driving the adjustingbar supporter 83 to reciprocate in a vertical direction, but not limited to. Instead of the cylinder device, a belt and a driving motor may be used so that they are coupled to the adjustingbar supporter 83 and driving the adjustingbar supporter 83 to reciprocate in the vertical direction. - Further, the thread
standby length adjuster 71 includes thetread transferring interceptor 91 provided between the bobbin and the thread standbylength adjusting body 73 and intercepting eachthread 3 transferred from the bobbin to the thread standbylength adjusting body 73. - The
thread transferring interceptor 91 is placed behind the thread standbylength adjusting body 73. As shown inFIG. 2B , thethread transferring interceptor 91 includes a supportingbracket 93 mounted on the thread standbylength adjusting body 73, and the supportingbracket 93 is formed with a throughhole 93 a through which the plurality ofthreads 3 transferred from the bobbin passes. - The supporting
bracket 93 is provided with aninterceptor 95 at an top side, theinterceptor 95 contacting and being spaced apart from the plurality ofthreads 3 transferred to thethread guiding unit 75 through the throughhole 93 a, and intercepting the plurality ofthreads 3 transferred to thethread guiding unit 75. - The
interceptor 95 is coupled to the supportingbracket 93 and can be lifted up and down. Here, theinterceptor 95 is connected to aninterceptor driver 101 by a pair ofrods 97 and a connectingbar 99. - The
interceptor driver 101 is preferably a cylinder device coupled to the connectingbar 99 and lifting theinterceptor 95 up and down toward the top surface of the supportingbracket 93. That is, theinterceptor driver 101 drives theinterceptor 95 to contact or be spaced apart from the plurality ofthreads 3 transferred to thethread guiding unit 75 along the top surface of the supportingbracket 93, thereby intercepting or allowing the plurality ofthreads 3 transferred to thethread guiding unit 75. - With this configuration, the
sewing machine 1 according to an embodiment of the present invention cuts thethread 3 as follows. - In the case where the
thread 3 connected to the needle working unit is cut during the embroidering work, the embroidering work is stopped. At this time, as shown inFIGS. 3A, 3B and 6, thecut thread 3 transferred from thethread supplying unit 11 to the needle working unit along the thread transferring path is retained on the thread take-upunit 9, and the cut end of thethread 3 is untwists so that it is not easy to thread the needle of the needle working unit. - Then, the
cylinder rod 49 of the drivingunit 45 is retracted, so that thecutter 33 of the cuttingunit 31 is moved to the cutting position, i.e., thecutting accommodating groove 23 of the supporting block 21 (refer toFIGS. 4A and 4B ). - As the
cylinder rod 49 of the drivingunit 45 is retracted, thelink 51 moves toward the drivingunit 45, and the supportingshaft 43 is rotated by therotation arm 59 and disposed on the same plane as thecylinder rod 49. At this time, theguide 53 is rotated toward the supportingblock 21 as the supportingshaft 43 rotates, thereby making thethread 3 retained on the thread take-upunit 9 be in contact with the front surface of the supportingblock 21. - Further, when the
cylinder rod 49 is more retracted, thecutter supporter 35 moves toward theguide 53 in the state that theguide 53 is in contact with the front surface of the supportingblock 21. At this time, as shown inFIGS. 5A, 5B and 7, the edge of thecutter 33 passes through the cutter throughhole 55 of theguide 53 and contacts and cuts thethread 3 disposed transversely to thecutter accommodating groove 23. At the same time, theelastic member 61 interposed between thecutter supporter 35 and theguide 53 is compressed. Here, the end of thecut thread 3 is clearly cut enough to be easily put to the needle of the needle working unit. - After cutting the
thread 3, as shown inFIG. 8 , the adjustingbar driver 85 is driven to make the thread standbylength adjusting bar 81 move down along the guide slit 79 of the thread standbylength adjusting body 73 while theguide 53 is in contact with the front surface of the supportingblock 21, thereby accommodating thecut thread 3 from the bobbin in thethread accommodating unit 77. At this time, thethread transferring interceptor 91 allows thethread 3 to be transferred. - After the
cut thread 3 is supplied from the bobbin to thethread accommodating unit 77 by a predetermined length, theinterceptor driver 101 drives thethread 3 to be not transferred from the bobbin to the thread standbylength adjusting body 73. - Then, as shown in
FIG. 9 , while thethread 3 is not transferred from the bobbin to the thread standbylength adjusting body 73, thecylinder rod 49 of thedriver 45 is expanded, thereby spacing theguide 53 from the supportingblock 21. At this time, thethread 3 retained on the thread take-upunit 9 and thethread 3 transferred from the thread take-upunit 9 to the needle working unit get out of thesewing machine 1. - Then, in order to return the cut thread 2 extended between the
cutter accommodating groove 23 and the bobbin to the needle working unit, the thread standbylength adjusting bar 81 is more moved down along the guide slit 79 of the thread standbylength adjusting body 73, thereby returning the end of thecut thread 3 to the standby position of thethread supplying unit 11, i.e., placing the end of thecut thread 3 in the connectingpipe 17 of thethread supplying unit 11. - Thus, the end of the
thread 3 snapped during the embroidering work is clearly cut enough to easily thread the needle of the needle working unit, and then returns to the thread standby position of thethread supplying unit 11, thereby completing preparation to supply thethread 3 to the needle working unit. - After completing the preparation, the air supply blows the high pressure air so as to transfer the
thread 3 accommodated in the connectingpipe 17 toward the needle working unit. Then, the threading unit (not shown) puts thethread 3 to the needle of the needle working unit, thereby making a sewing work possible. - Thus, the thread snapped during the embroidering work is automatically cut by the cutter, so that work efficiency is enhanced. Further, the cut thread is automatically returned to the thread standby position of the thread supplying unit in order to returning the cut thread to the needle working unit, thereby enhancing work efficiency.
- Meanwhile, it will be appreciated by those skilled in the art that the invention can be applied to the single needle automatic embroidering machine, a multi-needle automatic embroidering machine, a sewing machine, etc.
- As described above, the present invention provides a sewing machine, in which a thread snapped during an embroidering work is automatically cut, thereby enhancing work efficiency.
