Abstract
Description
- This invention relates to a thread-implanting machine to implant a number of threads into the base cloth and produce carpets and mats, etc.
- For the thread-implanting machine of the base cloth, refer to
FIG. 12 for the explanation of producing a carpet. -
FIG. 12 shows the cross-section drawing, and to produce a carpet,implant thread 101 intobase cloth 100 at a prescribed pitch while cutting every thread loop as well as implanting thethread 101 into thebase cloth 100. - A
needle 105 that moves up and down is placed in the body of the thread-implanting machine (not shown in the figure) and thethread 101 from a stock bobbin (not shown in the figure) is inserted through apinhole 105 a that is at the tip of theneedle 105. In addition, apivot shaft 107 is placed underneath theneedle 105 that oscillates by an oscillating mechanism (not shown in the figure) in response to the vertical movement of saidneedle 105, and an L-shaped shuttle hook 108 is attached to thispivot shaft 107. Asharp point 108 a of thisshuttle hook 108 is inserted into an after-mentioned thread loop that is formed by thethread 105, and acutting blade 108 b is placed underneath thepoint 108 a. Moreover, athread cutting blade 112 that is able to slide against thecutting blade 108 b of saidshuttle hook 108 moves up and down using an ascending-descendingshaft 113 as a supporting point in response to the vertical movement of saidneedle 105. - Subsequently, for the mechanism of the
needle 105, theshuttle hook 108 and thethread cutting blade 112 of said structure, refer toFIG. 12 for the explanation of the process of implanting thethread 101 into thebase cloth 100. - (1) The
needle 105 runs through thebase cloth 100 from the top dead center and hits the lowest point through an ascending-descending apparatus (not shown in the figure) of theneedle 105. At this time, thepoint 108 a of the L-shaped shuttle hook 108 moves close to thethread 101 by the oscillating mechanism (FIG. 12 (A)). - (2) Subsequently, when the
needle 105 starts moving up, thethread 101 inserting through thepinhole 105 a loosens and forms a thread loop. Then, by said oscillating mechanism, thepoint 108 a of the L-shaped shuttle hook 108 is inserted into the thread loop of the thread 101 (FIG. 12 (B)). - (3) Moreover, when the
needle 105 moves up, the length (distance) of thethread 101 between thebase cloth 100 and theneedle 105 is maintained at a certain length by thepoint 108 a of the L-shaped shuttle hook 108 that stays at the same position, and the needle moves further up and hits the top dead center above thebase cloth 100. When theneedle 105 hits the top dead center, thethread cutting blade 112 moves up and the thread is cut by thethread cutting blade 112 and thecutting blade 108 b that is formed on said shuttle hook 108 (FIG. 12 (C)). - After that, the
thread 101 is implanted into thebase cloth 100 and carpets etc. are produced by repeating said (1) to (3) with thebase cloth 100 being moved by 1 pitch. - However, because it repeats the operation of stopping, oscillating, stopping and waiting to cut, cutting the thread, oscillating back to the original position and stopping by the oscillating movement of said
shuttle hook 108, there is an impact shock at the time of stopping the oscillation when this sequence of operation is performed at high speeds, thus improvements on the noise problem are desired. - The needle on the thread-implanting machine of this invention has thread through its pinhole and runs up and down through the surface and undersurface of base cloth. In addition, the hook shaft turns in response to the vertical movement of this needle. Then, the turning hook, which has the turning hook blade and is attached to the hook shaft, and the ascending-descending blade by the turn of said hook shaft, cuts the thread, and sequentially, the thread is implanted. Therefore, because the turning hook (turning hook blade) cuts the thread with the ascending-descending blade while implanting, the noise is reduced.
- Moreover, because the ascending-descending blade that is used for the thread-implanting machine of this invention has a mechanism that it moves up and down by the eccentric cam that is attached to the turning shaft or the eccentric cam that is placed on the outside of the hook shaft and synchronizes with the hook shaft, it can be easily configured.
- In addition, because the thread-implanting machine of this invention has a rotary vane, attached, it can prevent the accumulation of thread waste and makes it possible to stitch at high speeds.

FIG. 12 is the basic concept of an existing thread-implanting machine. - Explaining this invention in greater detail.
- For the thread-implanting machine that produces carpets etc. by implanting into base cloth, refer to
FIG. 1 that shows the entirety andFIG. 2 that shows components underneath theneedle 51. - The ascending-descending mechanism that the
needle 51 runs up and down through thesurface 54 a and theundersurface 54 b of thebase cloth 54 is built in the body of the thread-implantingmachine 50, andthread 55 from thestock bobbin 52 is inserted through thepinhole 51 a that is formed on the tip of thisneedle 51. - Moreover, there is the hook
turning extension arm 60 underneath the body of the thread-implantingmachine 50, and thehook shaft 6 that turns in synchronization with the ascending-descending mechanism of saidneedle 51 is placed on the inside of this hookturning extension arm 60. In other words, it is a cycle in which the rotation is made from the top dead center of the needle 51 (on the surface of the implanting cloth 54) to the bottom dead center of the needle 51 (on the undersurface of the implanting cloth 54) to the top dead center of the needle 51 (on the surface of the implanting cloth 54). - The turning
hook 1, which is semicircular, is composed of anarm part 7 that is placed extending towards the exterior edge from the center and afalcate hook 4 that extends on a quasi-half circle from thisarm part 7, and aninductive groove 3 is formed between thishook 4 and thearm part 7. Then, this turninghook 1 is connected to thehook shaft 6 in the center part. - Additionally, the
sharp point 2 of thehook 4 is able to insert into a thread loop that is formed by the later-mentionedthread 55 c andthread 55 w, and thisthread 55 of the thread loop that has the hook inserting through is induced to a turninghook blade 5, which is one side of scissors that cut thethread 55 and are placed on the inside that is close to thearm part 7 of thehook 4, accompanying the turn ofshuttle hook 1. - Moreover, an
eccentric cam 8 that is in close contact with saidarm part 7 is attached to saidhook shaft 6. On the other hand, a plate-like ascending-descendingblade 10 that is oscillatable is attached to a supportingshaft 10 j by aspring 11 in the state where it is always placed on said eccentric cam. Then, acutting blade 10 a that is formed at the upper end of the ascending-descendingblade 10 comprises the other side of the scissors for saidshuttle hook blade 5. - Thus, turning
hook 1 andeccentric cam 8 turn counterclockwise in synchronization with the vertical movement of theneedle 51, and ascending-descendingblade 10 moves up by theeccentric cam 8, and said turninghook blade 5 and the ascending-descending blade slide against each other, and cut thread as scissors. - Next, the process of sequentially implanting into the
base cloth 54 accompanying the vertical movement of theneedle 51 will be described with reference toFIG. 3-8 . - The positions of the vertical movement of the
needle 51 is defined as sin θ function depending on the turning angle of theshuttle hook 1, and the positions of theneedle 51 and thepoint 2 of theturning hook 1 are recreated with a high degree of accuracy. - In addition, the
hook shaft 6 makes one rotation with the cycle ofneedle 51, which is from the top dead center (on thesurface 54 a) to the bottom dead center (on theundersurface 54 b) to the top dead center (on thesurface 54 a), and theneedle 51 runs up and down through thesurface 54 a and theundersurface 54 b of thebase cloth 54, andthread 55 is cut by the turninghook blade 5 of the turning hook and the ascending-descendingblade 10 and sequentially implanted into thebase cloth 54 by a pitch (P). - (1)
FIG. 3 shows that theneedle 51 that has thread 55 through itspinhole 51 a is on thesurface 54 a of thebase cloth 54 and is going down from the top dead center and also shows the state immediately before thepinhole 51 a sticks into thebase cloth 54. - In addition,
thread 55 that is threaded in thepinhole 51 a is connected to astock bobbin 52, and with regard to the dropping of theneedle 51, there is no sliding ofthread 55 that is restrained by thepinhole 51 a and theneedle 51 andthread 55 moved down together. Moreover, the slackness ofthread 55 a is equivalent to the length of one implanted piece of thread, and with the downward movement ofneedle 51, the length of one implanted piece of thread is pulled from thestock bobbin 52. - (2)
FIG. 4 shows the state thatneedle 51 drops further andneedle 51 has run throughbase cloth 54 and is under theundersurface 54 b and has hit the bottom dead center. In addition,thread pinhole 51 a are under tension of the friction of thebase cloth 54 and closely attaching toneedle 51. - (3)
FIG. 5 shows thatneedle 51 moves slightly up from the bottom dead center, and thethread pinhole 51 a, and at the same time,point 2 of the turning hook inserts into the thread loop accompanying the turn of the turningshaft 6 and the thread is hooked by thehook 4. - In addition, because the thread loop of the
thread 55 is hooked by thehook 4, this thread loop does not come through to the surface of thebase cloth 54 even ifneedle 51 moves up. - (4)
FIG. 6 shows that the shuttle hook has caracoled from the stateFIG. 3 , and theneedle 51 is moving up throughbase cloth 54, andthread hook 4, andthread 55 is moved up to the surface ofbase cloth 54 accompanying the upward movement ofneedle 51 while the thread loop that is formed withthread - (5)
FIG. 7 shows thatneedle 51 has moved further up and almost hits the top dead center, the thread loop slides to the turninghook blade 5 held by thehook 4, andneedle 51 is being pulled upward withthread 55 d sliding throughpinhole 51 a, and thethread 55 d is put into a state of tension. - In addition, it shows that ascending-descending
blade 10 moves up byeccentric cam 8 that is attached tohook shaft 6, and this is immediately before this ascending-descendingblade 10 and the turninghook blade 5 of the turninghook 1cut thread 55. - (6) In
FIG. 8 ,needle 51 hits the top dead center, and the turninghook blade 5 and ascending-descendingblade 10 move to the highest position, slide against each other, become scissors and cutthread base cloth 54 is moved by one pitch (P), and the next thread implantation is prepared. - In addition, the timing to move said
base cloth 54 by one pitch (P) is while theneedle 51 is above the surface of thebase cloth 54. -
FIG. 9 (A) shows the implanted thread that has been implanted into thebase cloth 54 when said cycle from (1) to (6) is sequentially performed using one piece of thethread 55, and each piece of implanting thread is cut into 55 g and 55 h and is implanted. Additionally,FIG. 9 (B) shows the state of one implanted thread, and shows the thread implantation state in which the thread is divided into two pieces on the undersurface ofbase cloth 54. - In addition, there is an explanation of an example that one piece of
thread 55 is inserted throughpinhole 51 a, however, several pieces of thread can be inserted throughpinhole 51 a and implanted. For example, if three pieces of thread are inserted throughpinhole 51 a, and said cycle (1)-(6) is performed, they are divided into three and three pieces as shown inFIG. 9 (C), which means that it can implant 6 pieces at a time. - As seen above, because the thread-implanting machine of this invention cuts thread with turning
hook blade 5 and ascending-descendingblade 10 when turninghook 1 turns, it moves smoothly unlike the oscillating movement of existing shuttle hooks and is able to implant quietly. - In addition, although ascending-descending
blade 10 is a simple mechanism that moves up byeccentric cam 8, it can be comprised to oscillate as existing one and cut thread with theshuttle hook blade 5. - Moreover,
FIG. 10 shows the components underneath theneedle 51 that have another structure, but a component that is different from the thread-implanting machine shown inFIG. 2 isrotary vane 40. Additionally, aturning hook 1A is a discotic that hasfalcate hook 4 and theturning hook blade 5 and has a different shape than said turninghook 1, but it has the same function. - The
rotary vane 40 is attached to the back of said ascending-descendingblade 10 on thehook shaft 6, andblades 41 are attached to thisrotary vane 40, and it turns along with the turn ofhook shaft 6 and blows winds forwards (to the direction of ascending-descending blade 10) to cool the scissor part that is composed of ascending-descendingblade 10 and theturning hook blade 5 as well as preventing thread waste from adhering and piling up. - In addition, this thread waste is made by the friction generated when the
thread 55 goes throughsmall pinhole 51 a, and the thread that goes through the small pinhole is peeled into micro fibers and scattered around, and this thread waste wraps around theturning hook 1 and, if left unattended, it becomes unable to operate. - Moreover, with regard to the cutting by turning
hook blade 5 and the ascending-descendingblade 10, because turninghook blade 5 and ascending-descendingblade 10 cut thread by sliding against reciprocal, theturning hook blade 5 and ascending-descendingblade 10 will burn due to frictional heat if the machine operates for a long time at high speed and is left unattended. - In this way, it is possible to prevent the accumulation of thread waste and the
turning hook blade 5 and the ascending-descendingblade 10 from burning and to continuously perform for a long time at high speeds by attaching therotary vane 40 to thehook shaft 6. - In addition, this
rotary vane 40 can be attached to the hook shaft that oscillates as well as the turningshaft 6 that turns to one direction, and it goes without saying that it is possible to apply this to various sorts of sewing machine etc. as well as thread-implanting machine. For example, thethread 55 is inserted throughpinhole 51 a, andbase cloth 54 is sewn byneedle 51 that runs up and down through the surface and undersurface ofbase cloth 54 and the bobbin thread (not shown in the figure), in other words, for the thread-implanting machine that does not cutthread 55, because the accumulated thread waste can be removed by the winds fromrotary vane 40 that is attached to a shaft that turns in one direction or oscillates, it is possible to stitch at high speeds. - Subsequently,
FIG. 11 is a front elevation view that shows the other ascending-descending mechanism of ascending-descending blade 10A, and the structure has a different position ofeccentric cam 8 from the one shown inFIG. 2 . - A cam shaft 30 is placed on the outside of a
turning hook 1A, and this cam shaft 30 and thehook shaft 6 have turning conduction in equal ratio by a wheel and are synchronized with each other, and aneccentric cam 31 is attached to cam shaft 30, and the ascending-descending blade 10A moves up by thiseccentric cam 31. In other words, theeccentric cam 31 is placed on the outside of thehook shaft 6. Moreover, this ascending-descending blade 10A is supported roughly in the center by apivot shaft 33, and a U-shapedfitting part 10 b that is formed on the heel of the ascending-descending blade 10A slides over theeccentric cam 31 and connects to it. - Therefore, as the
turning hook 1A turns on theshuttle shaft 6, the ascending-descending blade 10A is moved up (oscillates) byeccentric cam 31 on the cam shaft 30, and said turninghook blade 5 and thecutting blade 10 acut thread 55. - In this way, the ascending-
descending blade 10A can be configured so that it can be moved up (oscillatable) by theeccentric cam 31 that is attached to the cam shaft 30 that is placed on the outside of theturning hook 1 as well as being comprised to attach theeccentric cam 8 to thehook shaft 6 shown inFIG. 2 .
