Abstract

The invention claims a grey cloth pressing device which is not pushed back by counterforce from coil even if the grey cloth pressing member is projected, such that the grey cloth pressing member can advance and retreat in a large route. The grey cloth pressing device (10) is mounted in a triangular base sliding base (9) such that a pressing member (11) can advance and retreat. The pressing member (11) has a grey cloth pressing member (12a) in a lower front end and has a sliding plate (12b) in an upper base end. The sliding plate (12b) is interlinked with an interlocking member (1) to slide up and down. The sliding displacement of the interlocking member (13) is guided by a groove arranged in a base member (14) and is operated by driving a small gear (15) with a motor (16). When the grey cloth pressing member (12a) is projected, a fixing portion (11c) in an upper end of the pressing member (11) is fixed to a front end of an oscillating rod (17) to become a locking state, thus, the grey cloth pressing member is not pushed back by the counterforce from the coil.

Description

本発明は、横編機で針床に沿ってキャリッジを走行させながら編地を編成する際に、編成駆動される編針のフックに係止している編目を押える生地押え装置に関する。   The present invention relates to a fabric presser device that presses a stitch locked to a hook of a knitting needle that is knitted and driven when a knitted fabric is knitted while running a carriage along a needle bed with a flat knitting machine.

従来から、横編機では、編目をフックに係止している編針が歯口に進出する際に係止されている編目が一緒に付き上がったり、引下げ張力の弱い編端の編目が浮いたりするのを防止するために、生地押え装置が用いられる（たとえば、特許文献１参照）。生地押え装置は、針床から歯口に進出して編成動作を行う編針の底面側に、歯口を挟んで対向する針床側から生地押えを突出させて、編目を押えるように作用する。   Conventionally, in a flat knitting machine, when a knitting needle that is locked to a hook is advanced to the tooth opening, the stitch that is locked together rises or the stitch at the end of the knitting end that has a low pulling tension floats. In order to prevent this, a fabric presser is used (see, for example, Patent Document 1). The fabric presser device acts to press the stitches by projecting the fabric presser from the side of the needle bed opposite to the knitting needle on the bottom side of the knitting needle that advances from the needle bed to the tooth opening and performs the knitting operation.

生地押え装置は、たとえば手袋の指袋を順次編成する際のように、生地に充分な引下げ力を作用させることができないで、筒状に編成を行うような場合に、特に有効となる。ただし、指袋を編成するような場合は、編糸をいったん切断して、端糸の処理を行うための端糸処理装置を用いる（たとえば、特許文献２参照）。   The cloth presser device is particularly effective when knitting in a cylindrical shape without applying a sufficient pulling force to the cloth as in the case of sequentially knitting finger gloves. However, when knitting a finger pouch, an end yarn processing device for cutting the knitting yarn once and processing the end yarn is used (for example, see Patent Document 2).

端糸処理装置を用いるような場合は、生地押え装置の生地押えを、進退可能にしておく必要がある。特許文献１には、生地押えを溝付カムで駆動して進退させる構成が開示されている。
実開昭５４−１０６３５６号公報 特開２００５−８９９３３号公報 When using the end yarn processing device, the fabric presser of the fabric presser device needs to be able to advance and retreat. Patent Document 1 discloses a configuration in which a fabric presser is driven by a grooved cam to advance and retract.
Japanese Utility Model Publication No. 54-106356 JP 2005-89933 A

特許文献１に開示されているように、生地押えを溝付カムで駆動して進退させるためには、溝付カムを生地押えの進退方向とは垂直なキャリッジの走行方向に移動させる必要がある。特許文献２に示すような端糸処理装置を併用すると、生地押えは、端糸処理装置の上方から編針の底面側に進退させる必要があり、必要なストロークが大きくなり、溝付カムの移動量も大きくなる。しかしながら溝付カムを用いて端糸処理装置と併用すると、機械的に干渉しやすくなるので、生地押えを進退するストロークを大きくすることが困難となる。   As disclosed in Patent Document 1, in order to drive the fabric presser with the grooved cam to advance and retreat, it is necessary to move the grooved cam in the carriage traveling direction perpendicular to the advancement and retraction direction of the fabric presser. . When the end yarn processing device as shown in Patent Document 2 is used in combination, the fabric presser needs to be advanced and retracted from the upper side of the end yarn processing device to the bottom surface side of the knitting needle, the required stroke becomes large, and the movement amount of the grooved cam is increased. Also grows. However, when the grooved cam is used in combination with the end yarn processing device, mechanical interference easily occurs, and it is difficult to increase the stroke for moving the fabric presser back and forth.

生地押えを、進退する方向に直接駆動するようにすれば、溝付カムを用いて進退方向と垂直に駆動する場合のような併用する装置の制限を受けずに進退ストロークを大きくすることができると期待される。しかしながら、生地押えが突出状態で編目を押える際の反力を常に受けることになるので、編成時に編針とともに歯口に進出する編目で生地押えが押戻されるおそれがある。   If the fabric presser is driven directly in the advancing / retreating direction, the advancing / retreating stroke can be increased without being restricted by a device that is used in combination with a grooved cam that is driven perpendicularly to the advancing / retreating direction. It is expected. However, since the reaction force at the time of pressing the stitch is always received while the fabric presser is in a protruding state, the fabric presser may be pushed back by the stitch that advances into the tooth opening together with the knitting needle during knitting.

本発明の目的は、生地押えが突出状態でも編目からの反力で押戻されないで、生地押えを大きなストロークで進退させることが可能な生地押え装置を提供することである。   An object of the present invention is to provide a fabric presser device that can advance and retreat the fabric presser with a large stroke without being pushed back by a reaction force from the stitch even when the fabric presser is in a protruding state.

本発明は、横編機のキャリッジに搭載され、歯口の上方から、該キャリッジが走行する針床に対向する針床から歯口に進出する編針の底面側に突出する突出状態で、編針に係止されている生地の編目が編針とともに付き上がるのを防ぎ、歯口から退避することも可能な生地押え装置において、

含むことを特徴とする生地押え装置である。 The present invention is mounted on a carriage of a flat knitting machine, and protrudes from the upper side of the tooth opening to the bottom side of the knitting needle that advances from the needle bed facing the needle bed on which the carriage runs to the tooth opening. In the fabric presser device that prevents the stitches of the locked fabric from sticking up with the knitting needle and can also be withdrawn from the tooth opening,
A presser member that is formed with a fabric presser at the tip and is capable of sliding displacement in a direction to advance and retract the fabric presser on the bottom side of the knitting needle that advances from the opposite needle bed to the tooth opening,
An entraining member that slides and displaces the presser member in a direction to move the presser foot forward and backward ,
The spring is urged by the spring so as to suppress the sliding displacement and lock the presser member in the protruding state of the material presser, and the lock is released by the accompanying member when the accompanying member retracts the presser member from the protruding state of the presser foot. and a lock mechanism that will be,
It is the cloth presser device characterized by including.

A swing lever that locks the upper end of the presser member at the tip;
A roller provided near the tip of the swing lever,
The entraining member releases the lock by pressing a roller of the lock member at the upper end.

また本発明で、前記押え部材には、段差部が設けられ、
前記ロック機構は、先端で押え部材の段差部を係止してロックする揺動レバーを備え、
前記連行部材は、揺動レバーの先端を押え部材の段差部から離してロックを解除させる傾斜部を備えることを特徴とする。 In the present invention, the pressing member is provided with a stepped portion,
The locking mechanism includes a swing lever that locks the stepped portion of the presser member at the tip,
The entrainment member includes an inclined portion that releases the lock by separating the tip of the swing lever from the stepped portion of the pressing member.

また本発明で、前記押え部材の生地押えは、先端付近にキャリッジの走行方向に延びる長孔を有することを特徴とする。   In the present invention, the presser foot of the presser member has a long hole extending in the traveling direction of the carriage near the tip.

本発明によれば、駆動源で、先端に生地押えが形成される押え部材を、対向する針床から歯口に進出する編針の底面側に進退するように駆動することができる。生地押えを編針の底面側に進出させれば、突出状態の先端で編目を押えることができる。これによって、編目をフックに係止している編針が歯口に進出する際に係止されている編目が一緒に付き上がったり、引下げ張力の弱い編端の編目が浮いたりするのを防止することができる。生地押えを退避させれば、端糸処理装置な押え部材などを作用させる際に支障が生じないようにすることができる。ロック機構は、押え部材の突出状態で摺動変位を抑止するようにロックするので、生地押えに対する編目からの反力が直接連行部材には掛らないようにすることができ、押え部材が突出状態でも押戻されないので、生地押えの作用を安定に持続させることができる。また、連行部材が押え部材を連行して、生地押えが突出状態となるように摺動変位させれば、ばねで付勢されているロック機構によるロックを自動的に開始させることができるとともに、押え部材を退避させる際には、連行部材でロックを解除させることができる。   According to the present invention, it is possible to drive the presser member having the fabric presser formed at the tip thereof with the drive source so as to advance and retreat from the opposing needle bed to the bottom side of the knitting needle that advances to the tooth opening. If the fabric presser is advanced to the bottom surface side of the knitting needle, the stitch can be pressed at the protruding tip. This prevents the stitches that are locked when the stitches that are locked to the hooks from advancing into the mouth of the knitting needles from rising together or the stitches at the ends of the knitting ends where the pulling tension is weak. Can do. If the dough presser is retracted, it is possible to prevent troubles from occurring when a presser member such as an end yarn processing device is operated. Since the lock mechanism locks to prevent sliding displacement in the protruding state of the presser member, reaction force from the stitch against the fabric presser can be prevented from being applied directly to the entraining member, and the presser member protrudes. Since it is not pushed back even in the state, the operation of the fabric presser can be stably maintained. In addition, if the entraining member entrains the presser member and slides and displaces so that the fabric presser is in a protruding state, the lock mechanism that is biased by the spring can be automatically started, When the presser member is retracted, the lock can be released by the entrainment member.

また本発明によれば、ロック機構に備えられる揺動レバーの先端で押え部材の上端を係止してロックすることができる。揺動レバーの先端付近にはローラを備え、連行部材がローラを押すと、揺動レバーによる押え部材のロックを解除することができる。   Further, according to the present invention, the upper end of the presser member can be locked and locked at the tip of the swing lever provided in the lock mechanism. A roller is provided near the tip of the swing lever, and when the entraining member presses the roller, the lock of the press member by the swing lever can be released.

また本発明によれば、ロック機構に備えられる揺動レバーの先端で押え部材に設ける段差部を係止してロックすることができる。連行部材に設ける傾斜部では、ロック部材の先端を押え部材の段差部から離して、ロックを解除することができる。   Further, according to the present invention, the step provided on the presser member can be locked and locked at the tip of the swing lever provided in the lock mechanism. In the inclined portion provided in the entraining member, the lock can be released by separating the tip of the lock member from the stepped portion of the pressing member.

また本発明によれば、生地押えの先端で編目を押えることができなくても、先端付近に設ける長孔を利用して、確実に編目の付き上がりを防止することができる。   Further, according to the present invention, even if the stitch cannot be pressed at the tip of the fabric presser, the stitch can be reliably prevented from being lifted up by utilizing the long hole provided near the tip.

以下、図１〜図８で本発明の実施の一形態を概略的に示す。図９〜図１１で本発明の実施の他の形態を概略的に示す。各図の説明では、先行して説明している部分に対応する部分に、同一の参照符を付して、重複する説明を省略している部分がある。また、説明の便宜上、一部の構成の図示を省略している場合がある。   1 to 8 schematically show an embodiment of the present invention. 9 to 11 schematically show another embodiment of the present invention. In the description of each figure, there are portions where the same reference numerals are given to portions corresponding to the portions described in advance, and overlapping descriptions are omitted. For convenience of explanation, some components may not be shown.

図１は部分的な断面を含むように側面から見た横編機１としての構成を示す。横編機１は、編針２が多数並設される針床３を、歯口４を挟んで前後に備える。ただし、編針２を歯口４に進出させている側の針床の図示は省略する。歯口４では、中心線４ａとして示す方向が上下方向となり、針床３は歯口４側が高くなるように傾斜しているけれども、針床３をほぼ水平な角度となるようにして示す。   FIG. 1 shows a configuration of a flat knitting machine 1 as seen from the side so as to include a partial cross section. The flat knitting machine 1 includes a needle bed 3 on which a large number of knitting needles 2 are arranged side by side on the front and rear sides of the tooth opening 4. However, the illustration of the needle bed on the side where the knitting needle 2 is advanced to the tooth opening 4 is omitted. In the tooth opening 4, the direction shown as the center line 4 a is the vertical direction, and the needle bed 3 is inclined so that the tooth opening 4 side becomes higher, but the needle bed 3 is shown to have a substantially horizontal angle.

編針２は、先端にフック２ａが設けられ、給糸口５からフック２ａに供給される編糸を引込むと編目ループ６が形成される。編針２としては、スライダ２ｂでフック２ａを開閉する複合針を示すけれども、べらでフック２ａを開閉するべら針も用いられる。新たな編目を形成するためには、編目ループ６を針幹側に残してフック２ａを歯口４に進出させる。フック２ａに新たな編糸が供給されると、編針２は針床側に引込まれ、編目ループ６は相対的にフック２ａ側に移動する。スライダ２ｂなどでフック２ａが閉じていると、編目ループ６はフック２ａの外周側を通ってノックオーバし、生地７が形成される。横編機１では、紙面に垂直な、針床３の長手方向にキャリッジ９が走行し、キャリッジ９に搭載されるカム機構が編針２を駆動して編成動作を行わせる。   The knitting needle 2 is provided with a hook 2a at the tip, and a knitting loop 6 is formed when a knitting yarn supplied from the yarn feeder 5 to the hook 2a is drawn. As the knitting needle 2, a compound needle that opens and closes the hook 2a with the slider 2b is shown, but a latch needle that opens and closes the hook 2a with a latch is also used. In order to form a new stitch, the hook 2a is advanced to the tooth opening 4 while leaving the stitch loop 6 on the needle stem side. When a new knitting yarn is supplied to the hook 2a, the knitting needle 2 is drawn to the needle bed side, and the stitch loop 6 relatively moves to the hook 2a side. When the hook 2a is closed by the slider 2b or the like, the stitch loop 6 knocks over the outer peripheral side of the hook 2a, and the fabric 7 is formed. In the flat knitting machine 1, the carriage 9 travels in the longitudinal direction of the needle bed 3 perpendicular to the paper surface, and a cam mechanism mounted on the carriage 9 drives the knitting needle 2 to perform a knitting operation.

本実施形態の生地押え装置１０は、キャリッジ９に取付けられ、歯口４の上方から、キャリッジ９が臨む針床３とは歯口４を挟んで対向する針床から歯口４に進出する編針２の底面側に押え部材１１を進退させることができる。押え部材１１は、下方の先端に生地押え１２ａを有し、上方の基端に摺動板１２ｂを有する。摺動板１２ｂは、連行部材１３に連行されて、図では上下方向で示す摺動変位を行う。連行部材１３の摺動変位は、ベース部材１４に設ける溝で案内され、ピニオン歯車１５による駆動に従って行われる。ピニオン歯車１５は、駆動源としてのモータ１６の出力軸に取付られている。駆動源を備えているので、移動位置に対する制約が少ない状態で生地を押えることができる。   The fabric presser device 10 of the present embodiment is attached to the carriage 9, and the knitting needle that advances from above the tooth opening 4 to the tooth opening 4 from the needle bed facing the needle bed 3 facing the carriage 9 across the tooth opening 4. The presser member 11 can be advanced and retracted toward the bottom surface side of 2. The presser member 11 has a dough presser 12a at the lower end and a sliding plate 12b at the upper base end. The sliding plate 12b is entrained by the entraining member 13 and performs a sliding displacement shown in the vertical direction in the figure. The sliding displacement of the entraining member 13 is guided by a groove provided in the base member 14 and is performed according to driving by the pinion gear 15. The pinion gear 15 is attached to the output shaft of a motor 16 as a drive source. Since the drive source is provided, the fabric can be pressed with few restrictions on the movement position.

押え部材１１が下限付近まで編針２の裏面側に突出している突出状態では、押え部材１１の上端を、ロック機構としての揺動レバー１７の先端で係止して、摺動変位を抑止し、ロック状態とすることができる。揺動レバー１７は、揺動軸１７ａまわりに揺動変位が可能であり、先端付近にローラ１８を備え、ねじりコイルばね１９で先端が図の左方に突出するように、付勢されている。生地押え装置１０の前面は、カバー２０で覆われている。   In the protruding state in which the presser member 11 protrudes to the back side of the knitting needle 2 to near the lower limit, the upper end of the presser member 11 is locked by the tip of the swing lever 17 as a lock mechanism to suppress sliding displacement, It can be in a locked state. The oscillating lever 17 can be oscillated and displaced about the oscillating shaft 17a. The oscillating lever 17 is provided with a roller 18 in the vicinity of the tip, and is urged by a torsion coil spring 19 so that the tip protrudes to the left in the figure. . The front surface of the fabric presser 10 is covered with a cover 20.

横編機１では、生地押え装置１０とともに、端糸処理装置２１も併用される。端糸処理装置２１は、編糸の把持部２２や切断部２３を備え、歯口４の上方に架設される案内軸２４，２５に沿って、キャリッジ９と平行に移動する。移動のための駆動は、可動ラック２６によって行われる。可動ラック２６は、ホルダ２７内に収容されている。端糸処理装置２１は、ホルダ２７によっても支持される。ホルダ２７は、保持軌道２８に取付けられている。   In the flat knitting machine 1, the end yarn processing device 21 is used in combination with the fabric presser device 10. The end yarn processing device 21 includes a knitting yarn gripping portion 22 and a cutting portion 23, and moves in parallel with the carriage 9 along guide shafts 24 and 25 installed above the tooth opening 4. Driving for movement is performed by the movable rack 26. The movable rack 26 is accommodated in the holder 27. The end yarn processing device 21 is also supported by the holder 27. The holder 27 is attached to the holding track 28.

図２は、図１に示す生地押え装置１０の構成を正面側から見て、カバー２０を取外した構成として示す。押え部材１１の先端の生地押え１２ａには、先端付近に長孔１２ａを設けている。連行部材１３は、大略的にＵ字の形状を有し、連行部材１３でピニオン歯車１５に臨む内側の辺には、ラック１３ａが形成され、ピニオン歯車１５の外周の歯に噛合する。連行部材１３の昇降変位のための駆動は、ピニオン歯車１５がラック１３ａに対して行うので、キャリッジ９の走行方向となる図の横方向には大きなスペースをとらなくても、ストロークが大きい駆動を行うことができる。押え部材１１の摺動板１２ｂと連行部材１３との間には、圧縮コイルばね３０が設けられる。圧縮コイルばね３０の上端側は、押え部材１１のばね保持部１１ｂで保持される。   FIG. 2 shows the structure of the dough pressing device 10 shown in FIG. 1 as viewed from the front side, with the cover 20 removed. The dough presser 12a at the tip of the presser member 11 is provided with a long hole 12a in the vicinity of the tip. The entraining member 13 has a substantially U shape, and a rack 13 a is formed on the inner side of the entraining member 13 that faces the pinion gear 15, and meshes with teeth on the outer periphery of the pinion gear 15. The driving for moving up and down the entraining member 13 is performed by the pinion gear 15 with respect to the rack 13a. Therefore, the driving with a large stroke is performed without taking a large space in the lateral direction of the drawing, which is the traveling direction of the carriage 9. It can be carried out. A compression coil spring 30 is provided between the sliding plate 12 b of the pressing member 11 and the entraining member 13. The upper end side of the compression coil spring 30 is held by the spring holding portion 11 b of the pressing member 11.

連行部材１３には、ラック１３ａが形成される辺に対向する内側の辺付近に、圧縮コイルばね３０の下部を保持するばね保持部１３ｂも形成される。押え部材１１の摺動板１２ｂは、ピニオン歯車１５が設けられる内側が空いている形状を有し、下側には内部から摺動変位を案内するガイド板３１が嵌め込まれている。ガイド板３１は、取付けねじ３１ａ，３１ｂでベース部材１４に取付けられている。摺動板１２ｂの外部は、ベース部材１４に設けられる溝に嵌合して、摺動変位するように案内される。   The entrainment member 13 is also formed with a spring holding portion 13b that holds the lower portion of the compression coil spring 30 in the vicinity of the inner side facing the side where the rack 13a is formed. The sliding plate 12b of the pressing member 11 has a shape in which the inside on which the pinion gear 15 is provided is vacant, and a guide plate 31 for guiding sliding displacement from the inside is fitted on the lower side. The guide plate 31 is attached to the base member 14 with attachment screws 31a and 31b. The outside of the sliding plate 12b is fitted into a groove provided in the base member 14 and guided so as to be slidably displaced.

摺動板１２ｂの上端には、揺動レバー１７の先端で係止される係止部１１ｃを有する。揺動レバー１７の先端での係止部１１ｃの係止は、ねじりコイルばね１９による付勢で保持され、ロック状態となる。連行部材１３には、揺動レバー１７の先端でのロック状態を、揺動レバー１７の側方でローラ１８を押して解除する解除部１３ｃが設けられている。押え部材１１は、生地押え１２ａと摺動板１２ｂとに分けて、取付ねじ３２で固定している。生地押え１２ａと摺動板１２ｂとの間の空間には、軌跡３３で示すように、対向する針床側から編針のフックを進出させることができる。なお、押え部材１１は、生地押え１２ａと摺動板１２ｂとを分けているけれども、生地押え１２ａと摺動板１２ｂとを一体に形成することもできる。   At the upper end of the sliding plate 12b, there is a locking portion 11c that is locked at the tip of the swing lever 17. Locking of the locking portion 11c at the tip of the swing lever 17 is held by urging by the torsion coil spring 19 and enters a locked state. The entrainment member 13 is provided with a release portion 13c that releases the locked state at the tip of the swing lever 17 by pressing the roller 18 on the side of the swing lever 17. The presser member 11 is divided into a fabric presser 12a and a sliding plate 12b, and is fixed by mounting screws 32. In the space between the fabric presser 12a and the sliding plate 12b, as shown by a locus 33, a hook of a knitting needle can be advanced from the opposite needle bed side. Although the presser member 11 separates the presser foot 12a and the slide plate 12b, the presser foot 12a and the slide plate 12b can be integrally formed.

連行部材１３が下降する摺動変位を行うようにピニオン歯車１５で駆動されると、押え部材１１のばね保持部１１ｂの上部の当接部１１ｄに、連行部材１３の当接部１３ｄが当接し、押え部材１１も下方に連行する。連行部材１３が上昇する摺動変位を行うように駆動されると、連行部材１３のばね保持部１３ｂから圧縮コイルばね３０を介して、押え部材１１のばね保持部１１ｂに上昇力が伝達される。しかしながら、押え部材１１の係止部１１ｃが揺動レバー１７の先端で係止されてロックされていると、圧縮コイルばね３０を圧縮しつつ、連行部材１３のみが上昇する。後述するように、連行部材１３の解除部１３ｃがローラ１８を押圧する位置まで上昇すると、ロックが解除される。連行部材１３で、押え部材１１の係止部１１ｃに対応する側の部分は、ロックが解除されるまで揺動レバー１７の先端に当接しないように切り欠かれて、切欠部１３ｅが形成されている。   When the entraining member 13 is driven by the pinion gear 15 so as to perform the sliding displacement that descends, the abutting portion 13d of the entraining member 13 abuts on the abutting portion 11d of the upper portion of the spring holding portion 11b of the pressing member 11. The pressing member 11 is also taken downward. When the entraining member 13 is driven to move up and slide, the ascending force is transmitted from the spring holding portion 13b of the entraining member 13 to the spring holding portion 11b of the holding member 11 through the compression coil spring 30. . However, when the locking portion 11c of the pressing member 11 is locked by being locked at the tip of the swing lever 17, only the entraining member 13 is raised while compressing the compression coil spring 30. As will be described later, when the release portion 13c of the entraining member 13 rises to a position where the roller 18 is pressed, the lock is released. A portion of the entraining member 13 on the side corresponding to the locking portion 11c of the presser member 11 is cut out so as not to contact the tip of the swing lever 17 until the lock is released, thereby forming a cutout portion 13e. ing.

図３、図４、および図５は、押え部材１１、連行部材１３、および揺動レバー１７に関連する構成をそれぞれ示す。各図の（ａ）は正面から見た構成、（ｂ）は側面から見た構成をそれぞれ示す。図３（ｂ）に示すように、生地押え１２ａは、先端付近の板厚を薄くしている。これは、図１に示すように、可動シンカ８が歯口４の中心線４ａに接近していても、生地押え１２ａに接触しないようにするためである。図４に示すように、連行部材１３の上部は、解除部１３ｃよりも側端側に切欠部１３ｄが設けられている。図５に示すように、揺動レバー１７は、先端付近にはローラ１８が設けられ、基端側の揺動軸１７ａを中心に揺動変位が可能である。ねじりコイルばね１９は、図５（ｂ）では時計回り方向に、揺動レバー１７を、先端やローラ１８が左方に突出するように付勢している。   3, 4, and 5 show configurations related to the pressing member 11, the entraining member 13, and the swing lever 17, respectively. (A) of each figure shows the structure seen from the front, (b) shows the structure seen from the side, respectively. As shown in FIG. 3B, the dough presser 12a has a thin plate thickness near the tip. This is to prevent the movable sinker 8 from coming into contact with the fabric presser 12a even when the movable sinker 8 is close to the center line 4a of the tooth opening 4 as shown in FIG. As shown in FIG. 4, the upper portion of the entraining member 13 is provided with a notch portion 13d on the side end side with respect to the release portion 13c. As shown in FIG. 5, the swing lever 17 is provided with a roller 18 in the vicinity of the tip, and can be swung and displaced about a swing shaft 17a on the base end side. The torsion coil spring 19 urges the swing lever 17 in the clockwise direction in FIG. 5B so that the tip and the roller 18 protrude to the left.

図６は、生地押え装置１０としての主要部の構成を示す。摺動板１２ｂおよび連行部材１３は、上限付近まで上昇しており、揺動レバー１７の先端は、摺動板１２ｂの裏面側に当接しているけれども、係止はしていない。ピニオン歯車１５を回転させれば、ラック１３ａを介して連行部材１３を昇降変位させることができる。揺動レバー１７による係止が行われていないので、摺動板１２ｂも連行部材１３に連行されて昇降変位する。   FIG. 6 shows the configuration of the main part of the fabric presser 10. The sliding plate 12b and the entraining member 13 are raised to near the upper limit, and the tip of the swing lever 17 is in contact with the back side of the sliding plate 12b, but is not locked. If the pinion gear 15 is rotated, the entraining member 13 can be displaced up and down via the rack 13a. Since the rocking lever 17 is not locked, the sliding plate 12b is also moved up and down by being driven by the driving member 13.

図７は、揺動レバー１７の先端で押え部材１１の上端の係止部１１ｃを係止している状態（ａ）から係止を解除した状態（ｄ）まで、連行部材１３を上昇させる際の変化を示す。図７（ａ）は、図１および図２に対応する生地押え１２ａの突出状態であり、係止部１１ｃへの係止で摺動変位が抑制されるロック状態となっている。図７（ｂ）は、連行部材１３を少し上昇させている状態を示す。係止部１１ｃへのロックは継続しているので、摺動板１２ｂは上昇しないけれども、図示を省略している圧縮コイルばね３０が縮み、連行部材１３は上昇し、解除部１３ｃがローラ１８に接近する。図７（ｃ）は、連行部材１３の解除部１３ｃでローラ１８が押され、揺動レバー１７の先端が摺動板１２ｂの係止部１１ｃから外れてロックが解除される状態を示す。図７（ｄ）に示すように、さらに連行部材１３を上昇させると、ロックが外れた摺動板１２ｂも連行されて上昇する。ロック解除後は、常にローラ１８が連行部材１３の裏面に沿うようになり、揺動レバー１７の先端は連行部材１３の裏面から離れる状態を保つ。   FIG. 7 shows the case where the entraining member 13 is raised from the state (a) where the locking part 11c at the upper end of the pressing member 11 is locked at the tip of the swing lever 17 to the state (d) where the locking is released. Shows changes. FIG. 7A shows a protruding state of the fabric presser 12a corresponding to FIG. 1 and FIG. 2, and is in a locked state in which sliding displacement is suppressed by locking to the locking portion 11c. FIG. 7B shows a state where the entraining member 13 is slightly raised. Since the locking to the locking portion 11c continues, the sliding plate 12b does not rise, but the compression coil spring 30 (not shown) is contracted, the entraining member 13 is raised, and the release portion 13c is moved to the roller 18. approach. FIG. 7C shows a state in which the roller 18 is pushed by the releasing portion 13c of the entraining member 13, and the tip of the swing lever 17 is released from the engaging portion 11c of the sliding plate 12b to release the lock. As shown in FIG. 7D, when the entraining member 13 is further raised, the sliding plate 12b that has been unlocked is also entrained and raised. After unlocking, the roller 18 always follows the back surface of the entraining member 13, and the tip of the swing lever 17 is kept away from the back surface of the entraining member 13.

ロックが解除されている状態からロック状態への変化は、大略的に、（ｄ）から（ａ）まで、連行部材１３で押え部材１１を下降するように連行して行われる。たとえば、図６のように、ローラ１８が完全に連行部材１３の裏面に沿っている状態から、連行部材１３を下降させると、当接部１３ｄ，１１ｄを介する連行で、押え部材１１も下降し、図７（ｄ）の状態になる。ただし、連行部材１３が下降を続けると、当接部１３ｄ，１１ｄを介する下方への駆動で、押え部材１１は（c），(ｂ)，（ａ）で示す位置よりも下降しうる。連行部材１３が（ｂ）よりも下降すると、解除部１３ｃによるローラ１８への押圧は無くなり、揺動レバー１７は時計回り方向に揺動変位して、先端は押え部材１１の係止部１１ｃの上昇を抑えるロック状態となる。   The change from the unlocked state to the locked state is generally performed from (d) to (a) along with the entraining member 13 so as to lower the presser member 11. For example, as shown in FIG. 6, when the entraining member 13 is lowered from the state where the roller 18 is completely along the back surface of the entraining member 13, the presser member 11 is also lowered by entrainment via the contact portions 13 d and 11 d. Then, the state shown in FIG. However, if the entraining member 13 continues to descend, the pressing member 11 can descend from the positions indicated by (c), (b), and (a) by driving downward through the contact portions 13d and 11d. When the entraining member 13 is lowered from (b), the roller 18 is not pressed by the release portion 13c, the swing lever 17 is swung in the clockwise direction, and the tip of the engaging portion 11c of the presser member 11 is moved. It becomes the lock state which suppresses the rise.

生地押え１２ａの先端が編目を押えると、編目が付き上がる反力で押え部材１１も上昇力を受ける。揺動レバー１７による係止部１１ｃのロックで、押え部材１１の上昇を確実に防ぐことができ、連行部材１３の駆動源となるモータ１６には負荷がかからない。   When the tip of the fabric presser 12a presses the stitch, the presser member 11 also receives a rising force due to the reaction force with which the stitch is attached. The locking member 11c is locked by the swing lever 17 so that the presser member 11 can be reliably prevented from rising, and no load is applied to the motor 16 serving as the drive source of the entrainment member 13.

図８は、生地押え１２ａの先端付近に長孔１１ａを設ける効果を示す。図８（ａ）は、生地押え１２ａの先端で、編目ループ６を押えている状態を示す。ただし、長孔１１ａ付近は板厚が薄くなっているので、図８（ｂ）に示すように、編目ループ６を先端では押えられず、編針２の底面と生地押え１２ａとの間に編目ループ６が入って、編針２の進出に伴って編目ループ６も付き上がる場合があり得る。付き上がる編目ループ６でも、図８（ｃ）に示すように長孔１１ａの位置では落込み、さらに付き上がることは防止可能となる。なお、長孔１１ａは三つに分けて設けているけれども、一つにまとめるようにしてもよい。分けると、強度を確保することができる。分ける場合、孔が無い部分で、付き上がり防止の効果が得られなくなるけれども、生地押え装置１０はキャリッジ９とともに移動するので、付き上がりかけた編目ループ６をいずれかの孔に落込ませることができる。   FIG. 8 shows the effect of providing the long hole 11a in the vicinity of the tip of the fabric presser 12a. FIG. 8A shows a state in which the stitch loop 6 is pressed at the tip of the fabric presser 12a. However, since the plate thickness is thin in the vicinity of the long hole 11a, the stitch loop 6 cannot be pressed at the tip as shown in FIG. 8B, and the stitch loop is interposed between the bottom surface of the knitting needle 2 and the fabric presser 12a. 6 may enter, and the stitch loop 6 may move up as the knitting needle 2 advances. Even in the stitch loop 6 that rises, it is possible to prevent the stitch loop 6 from dropping at the position of the long hole 11a as shown in FIG. In addition, although the long hole 11a is divided and provided in three, you may make it combine in one. If divided, strength can be secured. In the case of dividing, although the effect of preventing the sticking up cannot be obtained at a portion where there is no hole, the fabric presser device 10 moves together with the carriage 9, so that the stitch loop 6 that has been lifted up can be dropped into any hole. .

図９は部分的な断面を含むように側面から見た横編機４１としての構成を示す。横編機４１は、生地押え装置５０を備える。生地押え装置５０では、押え部材５１の先端側に生地押え５２ａが設けられ、基端側に摺動板５２ｂが設けられる。連行部材５３をベース部材５４に収容し、ピニオン歯車１５によるラック５３ａへの昇降駆動で摺動板５２ｂを連行させる構成は、基本的に図１の生地押え装置１０と同様である。生地押え装置５０で生地押え装置１０に対応する部分には同一の参照符を付し、重複する説明を省略する。ベース部材５４では、連行部材５３の下端付近で摺動板５２ｂを係止するように、揺動レバー５７の揺動軸５７ａを支持している。揺動レバー５７は、図の時計回り方向にねじりコイルばね５９で付勢されている。摺動板５２ｂの表面側は、カバー６０で覆われている。   FIG. 9 shows a configuration of the flat knitting machine 41 as seen from the side so as to include a partial cross section. The flat knitting machine 41 includes a fabric presser device 50. In the fabric presser device 50, a fabric presser 52a is provided on the distal end side of the presser member 51, and a sliding plate 52b is provided on the proximal end side. The structure in which the entraining member 53 is accommodated in the base member 54 and the sliding plate 52b is entrained by the raising and lowering drive to the rack 53a by the pinion gear 15 is basically the same as that of the fabric presser 10 in FIG. Parts of the cloth presser device 50 corresponding to the cloth presser apparatus 10 are denoted by the same reference numerals, and redundant description is omitted. The base member 54 supports the swing shaft 57 a of the swing lever 57 so as to lock the sliding plate 52 b near the lower end of the entraining member 53. The swing lever 57 is biased by a torsion coil spring 59 in the clockwise direction in the figure. The surface side of the sliding plate 52 b is covered with a cover 60.

図１０は、図９の生地押え装置５０を正面側から見た構成を、カバー６０を取除いた構成として示す。揺動レバー５７の先端には、幅方向の右半分で押え部材５１としての摺動板５２ｂの段差部５１ｃが作用し、幅方向の左半分で連行部材５３の傾斜部５３ｃが作用する。   FIG. 10 shows the configuration of the fabric presser 50 shown in FIG. 9 as viewed from the front side, with the cover 60 removed. The step 51c of the sliding plate 52b as the pressing member 51 acts on the right half in the width direction and the inclined portion 53c of the entraining member 53 acts on the left half in the width direction on the tip of the swing lever 57.

図１１は、押え部材５１の段差部５１ｃ、連行部材５３の傾斜部５３ｃおよび揺動レバー５７の作用を示す。図１１（ａ）は、各部を切り離した状態で示す。ただし、実際の段差部５１ｃと傾斜部５３ｃとは、ほぼ同じ位置に並ぶように配置されている。図１１（ｂ）は、押え部材５１の段差部５１ｃを揺動レバー５７の先端で係止して摺動変位をロックしている状態を示す。図１１（ｃ）は、上昇する連行部材５３の傾斜部５３ｃで揺動レバー５７の先端を反時計回り方向に揺動変位させる直前の状態を示す。この状態から、ピニオン歯車１５でラック５３ａを駆動して、連行部材５３の傾斜部５３ｃを上昇させると、傾斜部５３ｃの傾斜面で揺動レバー５７を反時計回り方向に揺動させることができる。図１１（ｂ）のように、揺動レバー５７の先端が押え部材５１の段差部５１ｃを係止してロック状態となっていても、揺動レバー５７の反時計回り方向への揺動で、ロック状態を解除させることができる。   FIG. 11 shows the operation of the stepped portion 51 c of the pressing member 51, the inclined portion 53 c of the entraining member 53, and the swing lever 57. FIG. 11A shows a state where each part is cut off. However, the actual stepped portion 51c and the inclined portion 53c are arranged so as to be aligned at substantially the same position. FIG. 11B shows a state in which the stepped portion 51 c of the pressing member 51 is locked by the tip of the swing lever 57 to lock the sliding displacement. FIG. 11C shows a state immediately before the tip end of the swing lever 57 is swung in the counterclockwise direction by the inclined portion 53c of the ascending member 53 that moves up. From this state, when the rack 53a is driven by the pinion gear 15 to raise the inclined portion 53c of the entraining member 53, the swing lever 57 can be swung counterclockwise on the inclined surface of the inclined portion 53c. . As shown in FIG. 11B, even when the tip of the swing lever 57 is locked by locking the stepped portion 51c of the presser member 51, the swing lever 57 is swung counterclockwise. The locked state can be released.

以上で説明した生地押え装置１０，５０では、ピニオン歯車１５で連行部材１３，５３のラック１３ａ，５３ａを介して摺動変位するように駆動しているけれども、ベルトなどを介して摺動変位するように駆動してもよい。回転駆動ではなく、シリンダなどで、直線的に駆動してもよい。ロック機構は、ばね付勢される揺動レバー１７，５７を用いているので、ソレノイドなどのアクチュエータ等での駆動を必要としない。   In the cloth presser devices 10 and 50 described above, the pinion gear 15 is driven to slide and displace through the racks 13a and 53a of the entraining members 13 and 53, but it slides and displaces through a belt or the like. You may drive as follows. You may drive linearly with a cylinder etc. instead of rotational drive. Since the lock mechanism uses the swing levers 17 and 57 that are spring-biased, it does not need to be driven by an actuator such as a solenoid.

また、横編機１，４１では、生地押え装置１０，５０と端糸処理装置２１とを併用しているけれども、生地押え装置１０，５０のみを使用することも当然可能である。端糸処理装置２１を使用しない場合は、押え部材１１の昇降変位に必要なストロークを小さくし、キャリッジ９への取付け位置を歯口４に近づけることができる。   Further, in the flat knitting machines 1 and 41, the fabric presser devices 10 and 50 and the end yarn processing device 21 are used in combination, but it is naturally possible to use only the fabric presser devices 10 and 50. When the end yarn processing device 21 is not used, the stroke required for the upward / downward displacement of the presser member 11 can be reduced, and the attachment position to the carriage 9 can be brought closer to the tooth opening 4.
