Description

本発明はミシンのプーラー装置に関する。   The present invention relates to a puller device for a sewing machine.

ジーンズ等のミシン縫製において、生地送りの補助として、先引きプーラー装置が用いられる。先引きプーラー装置は、送り歯の後方（生地送り方向下流側）に該送り歯から布等被縫製物を引き出すための上下一対の駆動プーラーと従動プーラーを設置する（例えば、特許文献１，２参照）。
駆動プーラーは合成樹脂製あるいは鉄等金属製の所定プーラー幅のリムを回転軸体上に備えてなるが、一般に、ジーンズのような厚物生地では生地が滑らないように外周面に鋸歯を付けた鉄製のリムを備えた駆動プーラーが使用される。例えば、普通サイズ幅のウエストバンドの縫製に際しては、針幅が１／４−１−１／４（インチ）（総幅３８．１ｍｍ）、プーラー幅が５０．８ｍｍで足りていた。 In sewing a sewing machine such as jeans, a pull-up puller device is used as an aid for feeding the fabric. The leading puller device is provided with a pair of upper and lower drive pullers and a driven puller for pulling out a sewing object such as cloth from the feed dog behind the feed dog (downstream in the fabric feed direction) (for example, Patent Documents 1 and 2). reference).
The drive puller is equipped with a rim of a predetermined puller width made of synthetic resin or metal such as iron on the rotating shaft body. Generally, in the case of thick fabric such as jeans, serrated teeth are attached to the outer peripheral surface to prevent the fabric from slipping. A drive puller with an iron rim is used. For example, when sewing a normal-size width waistband, a needle width of 1 / 4-1-1 / 4 (inch) (total width of 38.1 mm) and a puller width of 50.8 mm are sufficient.

しかしながら、最近では、幅広のウエストバンドの需要に伴い、針幅も１／４（インチ）均等で１２本針（総幅６９．８５ｍｍ）、プーラー幅７８ｍｍという仕様が必要となってきており、かかる仕様では駆動プーラーの回転部分の総重量が増大することになる。駆動プーラーの回転部分の総重量が増えると、ミシンの回転数が増すにつれて慣性によるオーバーラン現象が激増し、縫目ピッチのばらつきが発生しやすいという問題があった。   However, recently, with the demand for a wide waistband, it has become necessary to specify a needle width equal to 1/4 (inch), 12 needles (total width 69.85 mm), and puller width 78 mm. The specification increases the total weight of the rotating part of the drive puller. When the total weight of the rotating portion of the drive puller increases, the overrun phenomenon due to inertia increases dramatically as the number of rotations of the sewing machine increases, and there is a problem that variations in stitch pitch are likely to occur.

本発明は、このような問題を解決するためになされたものであり、その目的とするところは、被縫製物の引っ張り機能を確保し得ながらプーラーの軽量化を図り得てオーバーランを抑え、縫目ピッチのばらつきを少なくすることのできるミシンのプーラー装置を提供することにある。   The present invention has been made in order to solve such a problem, and the object of the present invention is to reduce the weight of the puller while ensuring the pulling function of the sewing product, and to suppress overrun.

各分割リム９ａ，９ｂ，９ｃ，９ｄ・・・を回転軸体７に対し軸心方向に移動・固定自在に取り付ける手段としては、具体的には、図３、図４に示すように、ハウジング１４に複数個のねじ穴２７を軸線方向に列設し、各分割リム９ａ，９ｂ，９ｃ，９ｄ・・・にねじ挿通穴２８を設け、そのねじ挿通穴２８に挿通されるねじ２９をねじ穴２７群のうちのいずれかを選択してねじ込むことにより各分割リム９ａ，９ｂ，９ｃ，９ｄ・・・がハウジング１４に固定される。ねじ２９の頭部は分割リム９ａ，９ｂ，９ｃ，９ｄ・・・の外周面より沈ませて被縫製物と触れないようにしている。
ねじ穴２７はハウジング１４に直接あけるに代えて、図７に示すように、キー３０に複数個のねじ穴２７を軸線方向に列設し、そのキー３０をハウジング１４の外周面に設けた溝３１に嵌め込み固定することもできる。 As means for attaching each of the divided rims 9a, 9b, 9c, 9d... To the rotary shaft body 7 so as to be movable and fixed in the axial direction, specifically, as shown in FIGS. A plurality of screw holes 27 are arranged in the axial direction in 14, screw insertion holes 28 are provided in the respective divided rims 9 a, 9 b, 9 c, 9 d..., And screws 29 inserted through the screw insertion holes 28 are screwed. Each of the divided rims 9a, 9b, 9c, 9d,... Is fixed to the housing 14 by selecting any one of the holes 27 and screwing them. The heads of the screws 29 are sunk from the outer peripheral surfaces of the divided rims 9a, 9b, 9c, 9d.
Instead of directly opening the screw holes 27 in the housing 14, as shown in FIG. 7, a plurality of screw holes 27 are arranged in the axial direction in the key 30, and the key 30 is a groove provided on the outer peripheral surface of the housing 14. It can also be fitted and fixed to 31.

このように各分割リム９ａ，９ｂ，９ｃ，９ｄ・・・をハウジング１４にねじ２９で取り付けることにより、各分割リム９ａ，９ｂ，９ｃ，９ｄ・・・を所定間隔で並べられた複数本針１１の後方に位置するように回転軸体７に対し簡単に取り付けることができ、また取り付け後、針１１の配置変えに応じて各分割リム９ａ，９ｂ，９ｃ，９ｄ・・・の取り付け位置を簡単に変更することができる。但し、各分割リム９ａ，９ｂ，９ｃ，９ｄ・・・の回転軸体７に対する取り付け手段にはねじ２９による締め付け以外の取り付け手段を採用することもできる。 In this way, by attaching the divided rims 9a, 9b, 9c, 9d... To the housing 14 with the screws 29, a plurality of needles in which the divided rims 9a, 9b, 9c, 9d. 11 can be easily attached to the rotary shaft 7 so as to be located behind the actuator 11, and after the attachment, the attachment positions of the divided rims 9a, 9b, 9c, 9d. It can be changed easily. However, attachment means other than tightening with the screw 29 can be adopted as attachment means for the divided rims 9a, 9b, 9c, 9d.

分割リム９ａ，９ｂ，９ｃ，９ｄ・・・は、針幅が１／４インチ、２本の針１１を基準として、その針１１の後方位置に移動・固定できるように、ハウジング１４にねじ穴２７が１１個設けられる。例えば、図５、図６では、幅広のウエストバンドの縫製に対応すべく、針幅ｗを１／４（インチ）均等で１２本の針１１（総幅Ｗ＝６９．８５ｍｍ）、プーラー幅７８ｍｍという仕様に合わせて、リム９は分割リム９ａ，９ｂ，９ｃ，９ｄに４分割（各分割リムの幅は１２．４ｍｍ）して、総幅７８ｍｍの両端に分割リム９ａ，９ｄを２個、その間に分割リム９ｂ，９ｃを２個配置する。   The split rims 9a, 9b, 9c, 9d... Are threaded in the housing 14 so that the needle width is 1/4 inch and the two needles 11 can be moved and fixed to the rear position of the needles 11. Eleven 27 are provided. For example, in FIGS. 5 and 6, 12 needles 11 (total width W = 69.85 mm), puller width 78 mm, with a needle width w equal to ¼ (inch) to accommodate sewing of a wide waistband. In accordance with the above specifications, the rim 9 is divided into four divided rims 9a, 9b, 9c, 9d (the width of each divided rim is 12.4 mm), and two divided rims 9a, 9d are provided at both ends of a total width of 78 mm. Two split rims 9b and 9c are arranged between them.

上記のように構成した駆動プーラー５においては、各分割リム９ａ，９ｂ，９ｃ，９ｄ・・・は所定間隔で並べられた複数本の針１１の後方に位置するようにハウジング１４に配置するので、本来の被縫製物を引っ張るプーラー機能を確保することができる。
とくに、一つの回転軸体７上に所定間隔置きに配置させた分割リム９ａ，９ｂ，９ｃ，９ｄ・・・の総重量は、一つの回転軸体上に一括して配置した従来の一体リムの総重量に比べて（両者のプーラー総幅、リム径、リム厚みなどが同一の条件下で）、従来の一体リムの総重量よりも、隣り合う分割リム９ａ、９ｂどうし間、分割リム９ｂ，９ｃどうし間、分割リム９ｃ，９ｄどうし間のそれぞれの分割リム抜け部分だけ軽減することができ、それだけ駆動プーラー５の回転部分の重量が軽くなるため、オーバーラン現象を抑えることができ、ミシンの回転数が増すことに伴う縫目ピッチのばらつきを激減できるに至った。 In the drive puller 5 configured as described above, the divided rims 9a, 9b, 9c, 9d... Are arranged in the housing 14 so as to be positioned behind the plurality of needles 11 arranged at a predetermined interval. The puller function of pulling the original sewing product can be ensured.
In particular, the total weight of the divided rims 9a, 9b, 9c, 9d,... Arranged on the one rotating shaft 7 at predetermined intervals is the same as that of the conventional integrated rim arranged collectively on one rotating shaft. Compared to the total weight of the conventional integrated rim, and between the adjacent divided rims 9a, 9b and between the divided rims 9b (under the same conditions of the total width of the pullers, the rim diameter, the rim thickness, etc.). , 9c and between the divided rims 9c, 9d can only be reduced, and the weight of the rotating portion of the drive puller 5 can be reduced accordingly, so that the overrun phenomenon can be suppressed. As a result, the variation in the stitch pitch accompanying the increase in the number of rotations can be drastically reduced.
