Abstract

The shuttle thread(31) is supplied through guide grooves(21b, 22b) of a shuttle box(21) not using a bobbin from a spool. A shuttle thread supplying tube(30) is inserted in a throughhole(11a) of a rotating shaft(11), a bearing(11b) is installed on the inner wall of the rotating shaft(11). A clip holder(11c) is also joined on the upper part of the rotating shaft(11) to prevent a separation of the bearing(11b). The shuttle thread(31) is continuously supplied without being cut to the shuttle box(21) by the device.

본 발명은 재봉작업의 중단없이 연속적인 밑실 공급이 되도록한 재봉기의 밑실 공급장치에 관한것이다.The present invention relates to a lower thread supply device of the sewing machine to be a continuous lower thread supply without interruption of the sewing operation.

종래의 경우, 재봉기의 재봉작업은 상부의 재봉사와 북틀의 밑실이 교호적으로 천에 꿰매지면서, 재봉작업이 이루어지도록 되어있다.In the conventional case, the sewing operation of the sewing machine is to be made while the sewing thread of the upper sewing thread and the lower thread of the drum is alternately sewn on the cloth.

따라서, 재봉기의 연속사용으로 인하여 밑실이 떨어지게 되므로, 재봉작업이 이루어지지 않아 짧은시간마다 이를 보충하여야 하는 수작업이 필요하였다. 또한, 수십대의 재봉기를 사용하여 봉제작업을 하고 있는 사업장에서는 보빈(밑실을 감는 기구)의 교환을 위하여 수명의 작업인원이 항상 재봉기 가까이에서 주의를 기울여야하고, 그 인건비도 제품가격의 인상에 연결되는 요인이기도 했다. 이러한 문제점을 해소시키고자 최근에는 미싱의 아래실공급기구(일본공개특허 제90-23989참조)가 소개되어 있기도하나, 이는 회전축에 관통공을 축심방향으로 형성하여, 별도 구비한 실패에서 실을 연속적으로 공급되게 하는 기술이지만, 고속으로 회전되는 회전축 내부의 실이 관통공 내면벽에 마찰되거나 회전방향과 같은방향으로 회전되면서 간섭받게 되므로, 실이 끊어지는가 하면 서로 꼬이면서 공급이 이루어지지 않게되는 폐단이 불가피하였다.Therefore, since the lower thread is dropped due to the continuous use of the sewing machine, sewing work is not made, it was necessary to replenish it every short time. In addition, in workplaces where several tens of sewing machines are used to sew, workers of life should always pay close attention to the sewing machine for the replacement of bobbins. It was a factor. In order to solve this problem, a lower thread supply mechanism (see Japanese Laid-Open Patent Publication No. 90-23989) has recently been introduced to solve this problem, but it forms a through hole in the axis of rotation in the axial direction, so that the thread can be continuously It is a technology that allows the supply of oil, but because the thread inside the rotating shaft rotates at high speed is interfering with the inner wall of the through-hole or rotated in the same direction as the rotation direction, if the thread is broken or twisted with each other, the closed end This was inevitable.

따라서 본 발명은 상술한 바와같은 종래의 제반문제점을 충분히 감안하여 안출된 것으로서, 회전축에 관통공을 형성함과 동시에 일정부위에 베어링을 장착하고 그 내부에 고정관을 개재하여 회전축의 회전시에도 밑실의 공급에 지장됨이 없게한 재봉기의 밑실 공급장치를 제공하는데 그 목적을 둔 것이다.Therefore, the present invention has been devised in view of the above-mentioned problems in the related art, and forms a through hole in the rotating shaft, mounts a bearing at a predetermined position, and interposes the lower thread even when the rotating shaft is rotated through a fixed tube therein. It is an object of the present invention to provide a lower thread supply device of a sewing machine, which does not interfere with supply.

이하 첨부된 도면을 참조하여 본 발명의 목적을 달성하기 위한 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration for achieving the object of the present invention with reference to the accompanying drawings in detail.

북집(21)과 속가마(22) 및 겉가마(23)로 이루어진 하우징(20)이 선단에 결합되는 회전축(11)의 축심방향에 관통공(11a)을 형성하면서, 그 내주연에 베어링(11b)을 설치한다. 그리고, 밑실공급관(30)을 상기 회전축(11)의 관통공(11a)으로 삽입하고 밑실(31)의 공급을 유도하는 안내홈(21b)(22b)을 북집(21)과 속가마(22)의 중심축부재(21a)(22a)에 형성하여 구성된 것이다. 여기에서 미설명부호, 10a는 재봉기의 요홈, 11c는 베어링의 이탈을 방지하는 체결편, 11d는 회전축과 겉가마를 결합키위한 체결부재, 32는 실패를 지칭하는 것이다.The housing 20 formed of the bobbin 21, the inner kiln 22 and the outer kiln 23 forms a through hole 11a in the axial direction of the rotating shaft 11, which is coupled to the tip, and at the inner circumference of the bearing ( Install 11b). In addition, the bobbin 21 and the kiln 22 are guide grooves 21b and 22b for inserting the lower thread supply pipe 30 into the through hole 11a of the rotary shaft 11 and inducing supply of the lower thread 31. Is formed on the central shaft member (21a) (22a). Here, reference numeral 10a denotes a recess of the sewing machine, 11c denotes a fastening member for preventing detachment of the bearing, 11d denotes a fastening member for coupling the rotary shaft and the outer fork, and 32 denotes a failure.

이상과 같이 구성된 본 발명의 작용 및 효과를 일실시예를 들어 설명하면 다음과 같다.Referring to the embodiment and the operation and effect of the present invention configured as described above are as follows.

도면 제 1 도와 2도에서 보는 바와같이 별도구비된 실패(32)에서 밑실공급관(30)으로 밑실을 유도하여 북집(21)과 속가마(22)의 안내홈(21b)(22b)을 관통하여 보빈을 사용치 않고 바로 공급하게된다. 즉, 재봉기(10)는 미싱바늘의 상, 하 작용에 연동하여 밑실(31)이 공급되는데, 회전축(11)은 체결부재(11d)에 의해 겉가마(23)에 결착되어있고, 속가마(22)는 겉가마(23)에 결합되어 있다. 밑실(31)의 공급을 유도하는 밑실공급관(30)은 회전축(11)의 관통공(11a)에 삽입되고, 회전축(11) 내벽에는 도면 제 3 도 (b)에서 보는 바와 같이 베어링(11b)을 설치하고, 베어링(11b)의 이탈을 방지하는 체결편(11c)을 회전축(11) 선단부에 결합한다. 또한, 북집(21)은 속가마(22)의 중심축부재(22a)에 끼워지게된다. 여기에서 밑실의 공급경로는, 재봉기(10)의 요홈(10a)을 통해 회전축(11) 내부의 밑실공급관(30)을 따라가다 그 끝단에 이르러서는 겉가마(23)의 중심통공과 속가마 중심축부재(22a)의 안내홈(22b)을 거쳐 북집(21)의 안내홈(21b)으로 그 공급경로가 이루어지게 된다. 한편, 회전축(11)의 고속회전시에는 회전축(11) 내벽에 설치한 베어링(11b)이 밑실공급관(30) 외주연을 미끌어지면서 회전축(11)이 회전되고, 밑실공급관(30)은 회전되지 않는다. 또한, 회전축(11)과 결착되는 겉가마(23)는 회전축(11)과 동일방향으로 회전되지만, 속가마(22)와 북집(21)은 별도의 훅크부재(미도시하였음)에 걸려 있으므로, 회전축(11)의 회전과는 무관하게 회전되지 않는다. 즉, 밑실공급경로상에 놓인 주변부재는 회전축(11)의 회전에 의해 같이 연동되지 않으므로 밑실(32)의 공급에 있어서 전혀 간섭받지 않게된다. 한편, 본 발명의 속가마(22)와 북집(21)의 크기(l')는 종래기술의 속가마와 북집의 크기(l')보다 어느정도 축소하여, 밑실(31)을 공급경로상에 초기에 연결되게 하기 위한 작업이 월등히 수월해 진것이다.As shown in FIG. 1 and FIG. 2, the lower thread is guided to the lower thread supply pipe 30 from the separately provided failure 32 to penetrate through the guide grooves 21b and 22b of the bobbin 21 and the inner kiln 22. It is supplied immediately without using bobbins. That is, the sewing machine 10 is supplied with a lower thread 31 in conjunction with the upper and lower actions of the sewing needle, the rotary shaft 11 is fastened to the outer hook 23 by the fastening member 11d, 22 is coupled to the outer kiln (23). The lower thread supply pipe 30 for inducing the supply of the lower thread 31 is inserted into the through hole 11a of the rotating shaft 11, and the inner wall of the rotating shaft 11 has a bearing 11b as shown in FIG. 3 (b). And a fastening piece 11c that prevents the bearing 11b from being detached from the bearing 11b, and couples to the distal end portion of the rotating shaft 11. In addition, the bobbin 21 is fitted to the central shaft member 22a of the inner kiln 22. Here, the supply path of the lower thread follows the lower thread supply pipe 30 inside the rotary shaft 11 through the groove 10a of the sewing machine 10, and reaches the end thereof, through the center hole of the outer kiln 23 and the center of the inner kiln. The supply path is made to the guide groove 21b of the bobbin 21 through the guide groove 22b of the shaft member 22a. On the other hand, during the high speed rotation of the rotating shaft 11, the rotating shaft 11 is rotated while the bearing 11b installed on the inner wall of the rotating shaft 11 slides the outer periphery of the lower thread supply pipe 30, and the lower thread supply pipe 30 is not rotated. Do not. In addition, the outer kiln 23 which is engaged with the rotary shaft 11 is rotated in the same direction as the rotary shaft 11, but since the inner kiln 22 and the bobbin 21 is caught on a separate hook member (not shown), It does not rotate regardless of the rotation of the rotating shaft 11. That is, since the peripheral member placed on the lower thread supply path is not interlocked together by the rotation of the rotary shaft 11, there is no interference in the supply of the lower thread 32 at all. Meanwhile, the size l 'of the inner kiln 22 and the bobbin 21 of the present invention is reduced to some extent than the size l' of the conventional kiln and the bobbin of the prior art, so that the lower thread 31 is initialized on the supply path. It's much easier to get things connected.

이상에서 본 바와같이 밑실(31)을 공급하는 과정이 재봉기(10) 주변에 별도설치한 실패(32)에서 공급하게 되므로 밑실(31) 부족여부를 용이하게 알수있으며, 그 공급에 있어서도 회전축(11)의 회전과 상관없이 공급되므로, 끊어지거나 꼬이게 되는 종래기술의 문제점을 해결하게된 발명인 것이다.As seen above, the process of supplying the lower thread 31 is supplied from the failure 32 separately installed around the sewing machine 10, so it is easy to know whether the lower thread 31 is insufficient, and the rotation shaft 11 also in the supply thereof. Since it is supplied irrespective of the rotation of the), the invention is to solve the problems of the prior art that is broken or twisted.
