Description

【0001】
【産業上の利用分野】
本発明は、ミシンの上ルーパ軸に付与された余剰の潤滑油を上ルーパ支持台の上面に溜まらないようにしたミシンの上ルーパ支持台油逃がし装置に関するものである。
【0002】
【従来の技術】
従来、ミシンの上ルーパ支持台油逃がし装置としては、実開平7−283号公報に開示されているように、上ルーパ支持台の上面に設けられた油逃がし部(凹部)で行うようにしたものが知られている。上ルーパ支持台3Aは、図3に示されるように、ミシンフレーム1の前面にネジ2で固定されている。この上ルーパ支持台3Aは布送り方向Fに沿って穿設された円孔4を有する。円孔4の上下には、それぞれ開口部12,13が設けられている。円孔4は円柱状の上ルーパ軸案内5を回動自在に支持する。上ルーパ軸案内5の円周面には支持孔6が貫通されている。上ルーパ軸7は上ルーパ軸案内5の支持孔6と円孔4の開口部12,13とに挿通される。
【0003】
また、上ルーパ軸7はピン9を介してレバー10に連結されている。ピン9は中空の構造となっており、油芯紐19はその中空部分に挿入されている。レバー10は、図示を省略したミシン主軸に連動して揺動軸11を中心に揺動する。この揺動により、上ルーパ軸7は支持孔6内をスライドして昇降すると共に上ルーパ軸案内5を円孔4内で回動させ、上ルーパ8が略放物線状の軌跡を描くように運動する。ピン9の油芯紐19に浸透した潤滑油は、レバー10の揺動により飛散して噴霧状となり、上下にスライドする上ルーパ軸7の下部表面に付着する。
【0004】
上ルーパ支持台3Aには油逃がし部24(凹部)が設けられている。この油逃がし部24は、上ルーパ軸7が挿通される開口部12の近傍に配置され、ミシンの給油室に通じる逃がし孔25(図4参照)に接続されている。逃がし孔25の上部にはフィルタ26が設置されている。また、上ルーパ支持台3Aの上方には遮断板27が配置されている。この遮断板27の下端はルーパ支持台3Aの上面22上に接触されている。上ルーパ軸案内5には油分を浸透させたフェルト14が嵌め込まれている。フェルト14により上ルーパ軸7の表面に潤滑油が塗布される。つまり上ルーパ軸の表面には潤滑油が付与されることとなる。尚、この種のミシンフレームは一般的にミシン駆動に連動して円弧動する上メス腕を備えており、上メス腕は上ルーパ軸7の斜め上方に配置されている。
【0005】
上ルーパの昇降往復運動に伴って上ルーパ軸の表面から飛散して上ルーパ支持台上に落下する余剰の潤滑油の飛沫については、その一部が上ルーパ支持台の油逃がし孔を経て給油室等に戻される。また、上ルーパ支持台上に残った飛沫は蓄積されて大きな油玉となり、この油玉も重力により油逃がし孔を経て給油室等に戻される。さらに、遮断板は上ルーパ支持台の上面への潤滑油の広がりを防止している。
【0006】
【発明が解決しようとする課題】
ところが、従来のミシンの上ルーパ支持台油逃がし装置においては、上ルーパの昇降往復運動が高速化すると油玉の広がりが遮断板で遮られ、油玉の一部が上ルーパ支持台の上面より前に垂下していた。この垂下した油は、上ルーパ軸に連結された揺動レバーにより飛散したり、下方で蓄積されて機枠外に漏れたりしていた。これにより、生地や糸を汚損させることがあった。また、上ルーパ軸から飛散した油の一部が上メス腕にも付着していた。この付着した油は上メス腕の円弧動により飛散し、生地積載面の生地を汚損させることがあった。
従って、本発明の課題は、上ルーパ軸のスライドにより上ルーパ支持台の上面に溜まった油を上ルーパ支持台の前面に垂下させないことで生地や糸の汚損を防ぐようしたミシンの上ルーパ支持台油逃がし装置を提供することを目的としている。
【0007】
【課題を解決するための手段】
本発明は、上記目的を達成するために、ミシンフレームに固定され、布送り方向に沿って穿設された円孔と該円孔の上下にそれぞれ開口部とを設けた上ルーパ支持台と、上ルーパ支持台の円孔に回動自在に支持され、円周面に貫通された支持孔を有する上ルーパ軸案内と、上ルーパ軸案内の支持孔に挿通されると共に上ルーパ支持台の開口部に挿通された上ルーパ軸と、上ルーパ軸の表面に潤滑油を付与する手段と、上ルーパ支持台に設けられミシンの給油室に通じる逃がし孔を有する油逃がし部と、上ルーパ支持台の上方に配置された遮断板とを備えたミシンの上ルーパ支持台油逃がし装置において、遮断板の下端を上ルーパ支持台の油逃がし部の上方に配置すると共に門状に形成させたことを特徴とする。
【0008】
なお、遮断板について、ミシンフレームに備えられた上メス腕に隣接して凹面を付設するのが望ましく、また、遮断板の凹面に鉛直壁を付設しておくとよい。
【0009】
【作用】
本発明によれば、遮断板の下端を上ルーパ支持台の油逃がし部の上方に配置しているので、上ルーパ軸の昇降往復運動によって飛散した油が遮断板を伝うとその油は上ルーパ支持台の油逃がし部に流れ込む。なお、遮断板の下端を門状に形成しているので、ミシンが高速で駆動する等して油供給が過剰になっても上ルーパ支持台上に留まる油が遮断板で遮られず、また遮断板の下端より落下しようとする潤滑油が、上ルーパ支持台の油逃がし部に溜まる油と接触し難くなる。その結果、油逃がし部に溜まる油が弾き飛ばされずに上ルーパ支持台の上面より前に垂下しなくなる。油逃がし部に到達した油は逃がし孔を通じてミシンの給油室に戻される。
【0010】
なお、遮断板についてミシンフレームに備えられた上メス腕に隣接して凹面を付設しているので、上ルーパ軸から飛散してくる油の飛沫が上メス腕に付着しない。さらに、遮断板の凹面に鉛直壁を設けておくと、鉛直壁が防護カバーとなって容易に上メス腕で人体等に危害を与えることができなくなる。
【0011】
【発明の実施の形態】
以下、本発明に係る実施の形態を図面を用いて説明するが、図3および図4で述べた従来装置と共通する部分については同じ符号を付して説明を省略する。遮断板の下端27aは、上ルーパ支持台3Aの油逃がし部24上方に配置され、その形状は門状に形成されている。また、遮断板には、ミシンフレーム1に備えられた上メス腕31に隣接して凹面27bが付設されている。遮断板の凹面27bは上メス腕31と生地積載面32との間に配置されている。遮断板の凹面27bには鉛直壁27cが付設されている。この鉛直壁27cは、円弧動する上メス腕31と生地積載面32とを遮断するものである。上メス腕31は、公知の上メス機構に連結され、図示しないミシン主軸に連動して円弧動する。
【0012】
この実施の形態においてミシンを駆動すると、ピン9の揺動により飛散した潤滑油の飛沫は、上ルーパ軸7の下部表面に付着し、その上ルーパ軸のスライド運動により支持孔6の摺動面に給油される。また、その飛沫した油は上ルーパ軸案内5の円周面を経て円孔4の摺動面にも給油される。そして、上ルーパ軸案内5よりも上方にもたらされる余剰の油は、上ルーパ軸7のスライドによって飛散しても、遮断板により遮られる。遮断板によって遮られた油の飛沫が結合して大きな油玉になると、その油玉は、重力により遮断板の下端27aを経て上ルーパ支持台3Aの油逃がし部24に落下する。油逃がし部24に落下した油は、逃がし孔25を通じてミシンの給油室(図示せず)に戻される。
【0013】
油逃がし部24に落下する油が多量になっても、遮断板の下端27aが門状に形成されているので、上ルーパ支持台3A上に留まる油が遮断板27で遮られない。また、遮断板の下端より落下しようとする潤滑油が、上ルーパ支持台の油逃がし部に溜まる油と接触し難くなる。その結果、油逃がし部に溜まる油が、弾き飛ばされずに上ルーパ支持台3Aの上面22より前に垂下しなくなる。また、上ルーパ軸7から飛散した油の飛沫は遮断板の凹面27bにより上メス腕31に付着しない。本実施の形態では詳述していないが、遮断板の凹面に付着した油が遮断板の下端に流れ込むように、該凹面を傾斜させておくとよい。また、上ルーパ支持台の円孔は布送り方向に沿って穿設されていればよく、円孔の穿設箇所は上ルーパ支持台の前面あるいは背面のどちらからでもよい。
【0014】
【発明の効果】
以上のように、本発明によれば、上ルーパ軸の昇降往復運動によって飛散した油が、上ルーパ支持台の上面に落下して溜まったり、その溜まった油が上ルーパ支持台の上面より前に垂下することを防ぎ、生地や糸の汚損を防止できるという効果がある。なお、遮断板の下端を門状に形成しているので、ミシンが高速で駆動する等して油供給が過剰になっても上ルーパ支持台の油逃がし部に溜まる油が遮断板で遮られずに上ルーパ支持台の上面より前に垂下し難くなる。
【0015】
なお、上ルーパ軸から飛散してくる油が、遮断板に付設された凹面により上メス腕に付着しないので、上メス腕の円弧動によって油が飛散するのを防ぐことができる。更に、遮断板の凹面に鉛直壁を設けておくと、鉛直壁が防護カバーとなって容易に上メス腕で人体等に危害を与えることができなくなり、ミシン駆動時の安全性を向上させることができる。

[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper looper support oil release device for a sewing machine that prevents excess lubricating oil applied to an upper looper shaft of a sewing machine from collecting on an upper surface of an upper looper support base.
[0002]
[Prior art]
Conventionally, as an oil release device for an upper looper support base of a sewing machine, as disclosed in Japanese Utility Model Laid-Open No. 7-283, an oil release section (recess) provided on the upper surface of the upper looper support base is used. Things are known. The upper looper support 3A is fixed to the front surface of the sewing machine frame 1 with screws 2 as shown in FIG. The upper looper support 3A has a circular hole 4 formed along the cloth feeding direction F. Openings 12 and 13 are provided above and below the circular hole 4, respectively. The circular hole 4 rotatably supports the cylindrical upper looper shaft guide 5. A support hole 6 penetrates a circumferential surface of the upper looper shaft guide 5. The upper looper shaft 7 is inserted into the support hole 6 of the upper looper shaft guide 5 and the openings 12 and 13 of the circular hole 4.
[0003]
The upper looper shaft 7 is connected to a lever 10 via a pin 9. The pin 9 has a hollow structure, and the oil core cord 19 is inserted into the hollow portion. The lever 10 swings about a swing shaft 11 in conjunction with a sewing machine spindle (not shown). By this swing, the upper looper shaft 7 slides up and down in the support hole 6 and rotates the upper looper shaft guide 5 in the circular hole 4 so that the upper looper 8 moves so as to draw a substantially parabolic locus. I do. The lubricating oil that has permeated into the oil core string 19 of the pin 9 is scattered by the swing of the lever 10 and becomes a spray, and adheres to the lower surface of the upper looper shaft 7 that slides up and down.
[0004]
The upper looper support 3A is provided with an oil escape portion 24 (recess). The oil release portion 24 is disposed near the opening 12 through which the upper looper shaft 7 is inserted, and is connected to a release hole 25 (see FIG. 4) communicating with the oil supply chamber of the sewing machine. A filter 26 is provided above the escape hole 25. Further, a blocking plate 27 is disposed above the upper looper support 3A. The lower end of the blocking plate 27 is in contact with the upper surface 22 of the looper support 3A. A felt 14 impregnated with oil is fitted into the upper looper shaft guide 5. Lubricant is applied to the surface of the upper looper shaft 7 by the felt 14. That is, lubricating oil is applied to the surface of the upper looper shaft. This type of sewing machine frame generally has an upper knife arm that moves in an arc in conjunction with the sewing machine drive, and the upper knife arm is disposed diagonally above the upper looper shaft 7.
[0005]
With regard to the surplus lubricating oil splattered from the surface of the upper looper shaft and dropped onto the upper looper support due to the reciprocating movement of the upper looper, part of the lubrication oil is supplied through the oil escape hole of the upper looper support. Returned to the room. Further, the droplets remaining on the upper looper support stand accumulate and become large oil balls, and these oil balls are returned to the oil supply chamber and the like via the oil release hole by gravity. Further, the blocking plate prevents the lubricating oil from spreading on the upper surface of the upper looper support base.
[0006]
[Problems to be solved by the invention]
However, in the conventional oil release device of the upper looper support base of the sewing machine, when the reciprocating movement of the upper looper is accelerated, the spread of the oil balls is blocked by the blocking plate, and a part of the oil balls is removed from the upper surface of the upper looper support base. I was hanging down before. The dripping oil was scattered by the swinging lever connected to the upper looper shaft, or was accumulated below and leaked out of the machine frame. As a result, the fabric and the thread may be stained. In addition, part of the oil scattered from the upper looper shaft was also attached to the upper knife arm. The adhering oil was scattered by the circular motion of the upper knife arm, and sometimes soiled the fabric on the fabric loading surface.
Accordingly, an object of the present invention is to provide an upper looper support for a sewing machine that prevents the oil accumulated on the upper surface of the upper looper support base from sliding down on the front surface of the upper looper support base by sliding the upper looper shaft, thereby preventing the cloth and thread from being stained. It is intended to provide a tandem relief device.
[0007]
[Means for Solving the Problems]
The present invention, in order to achieve the above object, an upper looper support fixed to a sewing machine frame and provided with a circular hole formed along the cloth feeding direction and openings above and below the circular hole, An upper looper shaft guide rotatably supported in the circular hole of the upper looper support base and having a support hole penetrated in the circumferential surface, and an opening of the upper looper support base inserted through the support hole of the upper looper shaft guide. An upper looper shaft inserted into the upper portion, a means for applying lubricating oil to the surface of the upper looper shaft, an oil escape portion provided on the upper looper support base and having an escape hole communicating with a lubrication chamber of the sewing machine, and an upper looper support base The upper looper support base oil release device of the sewing machine having the blocking plate disposed above the upper looper support base and the gate lower shape. Features.
[0008]
It is preferable that a concave surface is provided on the blocking plate adjacent to the upper knife arm provided on the sewing machine frame, and a vertical wall is provided on the concave surface of the blocking plate.
[0009]
[Action]
According to the present invention, since the lower end of the blocking plate is disposed above the oil release portion of the upper looper support base, when oil scattered by the reciprocating motion of the upper looper shaft travels through the blocking plate, the oil is transferred to the upper looper. It flows into the oil release section of the support base. In addition, since the lower end of the blocking plate is formed in a gate shape, even if the sewing machine is driven at a high speed and the oil supply becomes excessive, the oil remaining on the upper looper support base is not blocked by the blocking plate, and Lubricating oil that is about to fall from the lower end of the blocking plate is less likely to come into contact with oil that accumulates in the oil escape portion of the upper looper support base. As a result, the oil that has accumulated in the oil escape section does not drop off and hang down before the upper surface of the upper looper support base. The oil that has reached the oil release section is returned to the oil supply chamber of the sewing machine through the release hole.
[0010]
Since the blocking plate is provided with a concave surface adjacent to the upper knife arm provided on the sewing machine frame, oil droplets scattered from the upper looper shaft do not adhere to the upper knife arm. Further, if a vertical wall is provided on the concave surface of the blocking plate, the vertical wall serves as a protective cover, so that the upper knife arm cannot easily harm a human body or the like.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment according to the present invention will be described with reference to the drawings, but the same reference numerals will be given to portions common to those of the conventional device described with reference to FIGS. 3 and 4, and description thereof will be omitted. The lower end 27a of the blocking plate is arranged above the oil release portion 24 of the upper looper support 3A, and has a gate-like shape. The blocking plate has a concave surface 27b adjacent to the upper knife arm 31 provided on the sewing machine frame 1. The concave surface 27 b of the blocking plate is disposed between the upper knife arm 31 and the fabric loading surface 32. A vertical wall 27c is attached to the concave surface 27b of the blocking plate. The vertical wall 27c blocks the upper knife arm 31 that moves in an arc and the fabric loading surface 32. The upper knife arm 31 is connected to a known upper knife mechanism, and moves in an arc in conjunction with a main shaft of a sewing machine (not shown).
[0012]
In this embodiment, when the sewing machine is driven, the splash of the lubricating oil scattered by the swing of the pin 9 adheres to the lower surface of the upper looper shaft 7, and the sliding motion of the upper looper shaft causes the sliding surface of the support hole 6 to slide. Refueled. The splashed oil is also supplied to the sliding surface of the circular hole 4 via the circumferential surface of the upper looper shaft guide 5. The surplus oil brought above the upper looper shaft guide 5 is blocked by the blocking plate even if it is scattered by the slide of the upper looper shaft 7. When the oil droplets blocked by the blocking plate combine to form a large oil ball, the oil ball drops to the oil release portion 24 of the upper looper support 3A via the lower end 27a of the blocking plate due to gravity. The oil that has fallen into the oil release section 24 is returned to the oil supply chamber (not shown) of the sewing machine through the release hole 25.
[0013]
Even if a large amount of oil falls into the oil escape portion 24, the lower end 27a of the blocking plate is formed in a gate shape, so that the oil remaining on the upper looper support 3A is not blocked by the blocking plate 27. Further, the lubricating oil that tends to drop from the lower end of the blocking plate hardly comes into contact with the oil accumulated in the oil escape portion of the upper looper support base. As a result, the oil that accumulates in the oil escaping portion does not drop down before the upper surface 22 of the upper looper support 3A without being flipped off. Further, the splash of oil scattered from the upper looper shaft 7 does not adhere to the upper knife arm 31 due to the concave surface 27b of the blocking plate. Although not described in detail in the present embodiment, the concave surface may be inclined so that oil adhering to the concave surface of the blocking plate flows into the lower end of the blocking plate. Further, the circular hole of the upper looper support may be formed in the cloth feeding direction, and the circular hole may be formed from either the front or the rear of the upper looper support.
[0014]
【The invention's effect】
As described above, according to the present invention, the oil scattered by the reciprocating motion of the upper looper shaft falls and accumulates on the upper surface of the upper looper support, or the accumulated oil is located in front of the upper surface of the upper looper support. This has the effect of preventing the fabric from hanging down and preventing the fabric and yarn from being stained. In addition, since the lower end of the blocking plate is formed in a gate shape, even if the sewing machine is driven at high speed and the oil supply becomes excessive, the oil accumulated in the oil escape portion of the upper looper support stand is blocked by the blocking plate. And it is difficult to hang down before the upper surface of the upper looper support base.
[0015]
Since the oil scattered from the upper looper shaft does not adhere to the upper knife arm due to the concave surface attached to the blocking plate, it is possible to prevent the oil from being scattered by the circular motion of the upper knife arm. In addition, if a vertical wall is provided on the concave surface of the blocking plate, the vertical wall can serve as a protective cover, making it difficult for the upper knife arm to easily harm the human body, etc., and improving the safety when driving the sewing machine. Can be.
