Description

本願発明は、綜絖枠毎に専用の駆動モータを備え、各駆動モータを織機の運転に同期して制御するいわゆる電子開口装置、又はドビー機構の接続、非接続を電気的に制御するいわゆる電子ドビー、あるいは各経糸の支持針の作動が電気的に制御されるジャカードにおいて実施される織布の裏織り方法と装置に関するものである。   The present invention includes a so-called electronic opening device that includes a dedicated drive motor for each frame and controls each drive motor in synchronization with the operation of the loom, or a so-called electronic dobby that electrically controls connection / disconnection of the dobby mechanism. Alternatively, the present invention relates to a woven fabric back weaving method and apparatus implemented in a jacquard in which the operation of the support needle of each warp is electrically controlled.

柄織物は通常意匠図から作成した織り柄パターンを基に経糸の開口を制御し、織り柄が表(織機上の織物表面)に出るようにして製織される(このような織り方を本願明細書では表織りと称する)。しかし、織り柄が表面に出ていると汚れ易くなり、また織り柄によっては多数の経糸が上方に位置することによる製織性の悪化、特に綜絖枠を使用する場合、多数の綜絖枠が上方に位置すると大きな負荷が開口駆動部に掛かるため、製織性が悪化し易い。これらの問題を解消する方策として、表に出る織り柄を織機上で織物の裏側に出るようにしたいわゆる裏織りが採用されている。   Pattern fabric is woven so that the opening of the warp is controlled based on the weave pattern pattern created from the design drawing, and the weave pattern comes out on the surface (the surface of the fabric on the loom). In the book, it is called a table weave.) However, if the woven pattern comes out on the surface, it becomes easy to get dirty, and depending on the woven pattern, the weaving property deteriorates due to the fact that a large number of warps are located above, especially when using a cocoon frame, When positioned, a large load is applied to the opening drive unit, so that the weaving property tends to deteriorate. As a measure for solving these problems, a so-called back weaving is adopted in which a weaving pattern appearing on the front surface is exposed on the back side of the fabric on the loom.

このような裏織りは、通常表織りの織り柄パターンを基に裏織り用の織り柄パターンを作成し、さらに裏織り用の織り柄パターンに合わせて綜絖枠毎に経糸の通し換え(ジャカードの場合は支持針に対する経糸の通し換え)という非常に煩雑な作業を行わなければ実現できなかった。   For this kind of back weaving, we usually create a weaving pattern for the back weaving based on the weaving pattern for the front weaving, and then change the warp thread for each frame (Jacquard) to match the weaving pattern for the back weaving. In the case of (1), it was not possible to achieve it without carrying out a very complicated operation of changing the warp to the support needle.

特許文献1には、ジャカード用の紋紙穿孔方法に関して、意匠図から作成した緯糸1本毎のテープ信号を180°反転して穿孔機に出力し、テープの穿孔を行うことにより新たな意匠図を作成すること無く反転意匠を作成する発明が開示されている。この特許文献1の明細書の末尾には、反転した織り柄パターンの紋紙を用いて製織すると反転しない意匠と同じ柄を織物の裏側に出現させることができると記載されている。
特開昭56−96931号公報
Patent Document 1 discloses a new design for a jacquard pattern punching method by turning a tape signal for each weft created from a design drawing 180 ° and outputting it to a punching machine to punch the tape. An invention for creating a reverse design without creating a figure is disclosed. At the end of the specification of Patent Document 1, it is described that the same pattern as a design that does not invert can appear on the back side of the woven fabric when weaving using a pattern paper with an inverted weave pattern.
JP-A-56-96931

しかし、ジャカードでは通常色糸を多数用いているため、反転した織り柄パターンで製織した織物の裏側は柄の色が反転してしまい、表織りの場合と同一の柄を織ることができない。特許文献1の反転意匠を用いて裏織りする場合は、やはり反転意匠に合わせた経糸の通し換えを行わなければ表織りと同一の織り柄を得ることができない。特許文献1の反転意匠を、綜絖枠を用いる電子開口装置や電子ドビーの織り柄パターンとして用いても同様の問題が発生する。   However, since jacquard usually uses a large number of colored yarns, the pattern color is reversed on the back side of the fabric woven with the reversed weave pattern, and the same pattern as in the case of the front weave cannot be woven. When weaving using the reversal design of Patent Document 1, the same weave pattern as the front weave cannot be obtained unless the warp thread is changed according to the reversal design. The same problem occurs even if the reversal design of Patent Document 1 is used as an electronic opening device using an eaves frame or an electronic dobby weave pattern.

本願発明の目的は、経糸開口装置の作動を電気的に制御するようにした織機において、経糸の通し換え作業を必要とせずに表織りと同じ織り柄を裏織りで製織できる織布の裏織り方法および装置を提供することにある。   The object of the present invention is to provide a back weaving of a woven fabric that can weave the same weave pattern as a front weaving with a back weaving without requiring a warp threading operation in a loom designed to electrically control the operation of the warp opening device.

請求項2に記載の本願発明は、前記裏織り用の織り柄パターンは、織成順序に従って都度生成されることを特徴とするため、必要な時に都度裏織り用の織り柄パターンを生成すればよいので、織り柄パターン保存のための記憶容量を増やす必要が無い。   The invention of claim 2 is characterized in that the woven pattern for back weaving is generated each time according to the weaving order. Therefore, if a weaving pattern for back weaving is generated whenever necessary. Since it is good, there is no need to increase the storage capacity for storing the woven pattern.

(第1の実施形態)
以下、第1の実施形態を図1〜図4に基づいて説明する。
(First embodiment)
Hereinafter, a first embodiment will be described with reference to FIGS.

第1の実施形態は経糸開口装置である電子開口装置に本願発明を実施した例を示す。図1において、説明の便宜上4枠で示した綜絖枠S1、S2、S3、S4と同数の専用の駆動モータM1、M2、M3、M4が織機のフレーム(図示せず)の側方に配設されている。各駆動モータMn(n=1〜4)の回転軸1、2、3、4の先端にはそれぞれ駆動ギヤ5、6、7(回転軸4の駆動ギヤは図示せず)が固定され、各回転軸1、2、3、4の後端にはそれぞれ駆動モータMn(n=1〜4)の回転角度を検出するロータリエンコーダ8、9、10、11が取り付けられている。   1st Embodiment shows the example which implemented this invention in the electronic opening device which is a warp opening device. In FIG. 1, the same number of dedicated drive motors M1, M2, M3, M4 as the saddle frames S1, S2, S3, S4 shown as four frames for convenience of explanation are arranged on the side of the loom frame (not shown). Has been. Driving gears 5, 6, and 7 (the driving gear of the rotating shaft 4 is not shown) are fixed to the tips of the rotating shafts 1, 2, 3, and 4 of the respective driving motors Mn (n = 1 to 4). Rotary encoders 8, 9, 10, and 11 for detecting the rotation angle of the drive motor Mn (n = 1 to 4) are attached to the rear ends of the rotary shafts 1, 2, 3, and 4, respectively.

一方、織機フレームの側方に配設された支軸12には、各綜絖枠Sn(n=1〜4)に対応した数の偏心輪17、18、19、20と一体化された被動ギヤ13、14、15、16が回転可能に支持されている。各被動ギヤ13、14、15、16は各駆動モータMn(n=1〜4)の駆動ギヤ5、6、7(駆動モータM4の駆動ギヤは被動ギヤ16に隠れているため、図示せず)と噛合し、各偏心輪17、18、19、20は対応する各綜絖枠Sn(n=1〜4)と公知のリンク機構21、22、23、24によって連結されている。   On the other hand, on the support shaft 12 disposed on the side of the loom frame, a driven gear integrated with a number of eccentric rings 17, 18, 19, and 20 corresponding to each frame Sn (n = 1 to 4). 13, 14, 15, 16 are rotatably supported. The driven gears 13, 14, 15, and 16 are not shown in the figure because the driving gears 5, 6, and 7 of the driving motors Mn (n = 1 to 4) are hidden by the driven gear 16. ), And the eccentric wheels 17, 18, 19, and 20 are connected to the corresponding flange frames Sn (n = 1 to 4) by known link mechanisms 21, 22, 23, and 24, respectively.

従って、各駆動モータMn(n=1〜4)が回転されると、それぞれ回転軸1、2、3、4、駆動ギヤ5、6、7(回転軸4の駆動ギヤは図示せず)、被動ギヤ13、14、15、16、偏心輪17、18、19、20及びリンク機構21、22、23、24を介して各綜絖枠Sn(n=1〜4)が上方又は下方に開口され、所定の開口運動が行われる。   Therefore, when each drive motor Mn (n = 1 to 4) is rotated, the rotation shafts 1, 2, 3, 4, drive gears 5, 6, 7 (the drive gear of the rotation shaft 4 is not shown), Each collar frame Sn (n = 1 to 4) is opened upward or downward via the driven gears 13, 14, 15, 16, the eccentric wheels 17, 18, 19, 20 and the link mechanisms 21, 22, 23, 24. A predetermined opening movement is performed.

電子開口装置の開口運動を制御するコンピュータからなる開口制御装置C1は、各駆動モータMn(n=1〜4)及びロータリエンコーダ8、9、10、11に接続し、各駆動モータMn(n=1〜4)の回転制御を行う。   An aperture control device C1 comprising a computer for controlling the aperture motion of the electronic aperture device is connected to each drive motor Mn (n = 1 to 4) and rotary encoders 8, 9, 10, and 11, and each drive motor Mn (n = The rotation control of 1-4) is performed.

織機駆動モータ25はコンピュータで構成される織機の制御装置Cからの指令を受けて起動する。織機の制御装置Cは、織機運転のための各種プログラムを記憶する記憶部ROM、データの記憶や書き換えが可能な記憶部RAM及びデータの各種演算や指令を行う演算処理部CPUを備えている。織機運転中は織機の回転角度を検出するロータリエンコーダ26から回転角度信号が織機の制御装置Cに送信され、織機の制御装置Cからは織機を運転するための各種制御指令が発信される。また、ロータリエンコーダ26の回転角度信号は開口制御装置C1にも出力され、織機の運転と電子開口装置が同期するように制御されている。   The loom drive motor 25 is activated in response to a command from the loom control device C constituted by a computer. The loom control device C includes a storage unit ROM that stores various programs for operating the loom, a storage unit RAM that can store and rewrite data, and an arithmetic processing unit CPU that performs various calculations and commands of data. During the loom operation, a rotary angle signal is transmitted from the rotary encoder 26 that detects the rotation angle of the loom to the loom control device C, and various control commands for operating the loom are transmitted from the loom control device C. The rotation angle signal of the rotary encoder 26 is also output to the opening control device C1, and the operation of the loom and the electronic opening device are controlled to be synchronized.

織機の制御装置Cに接続されたデータ入力装置27はデータ入力用のカード挿入口28を備えたキーボード29及び表示装置30からなり、織機の制御装置Cに接続されている。データ入力装置27からは、織機を運転するための各種制御データとともに図2に示した電子開口装置の開口運動を制御するための表織り用の織り柄パターンWP(以下、単に織り柄パターンWPと称する)がカード又は手作業により入力され、織機の制御装置Cのデータ記憶部RAMに記憶される。
なお、31は筬、Yは各綜絖枠Sn(n=1〜4)に支承された経糸、Wは織布を示す。
The data input device 27 connected to the loom control device C includes a keyboard 29 having a data insertion card insertion slot 28 and a display device 30, and is connected to the loom control device C. From the data input device 27, along with various control data for operating the loom, a weaving pattern WP for front weaving (hereinafter simply referred to as weaving pattern WP) for controlling the opening movement of the electronic opening device shown in FIG. Is input by card or manual operation and stored in the data storage RAM of the control device C of the loom.
In addition, 31 is a kite, Y is the warp supported by each kite frame Sn (n = 1-4), W shows a woven fabric.

織機の制御装置Cに記憶された織り柄パターンWPは、表示装置30のタッチパネル方式で構成された表示画面32に表示させることができる。織り柄パターンWPは横軸に綜絖枠Sn(n=1〜8)(織機で多く使われる8枚の綜絖枠で示している)を示し、縦軸に織り柄パターンWPの織成順序、即ち綜絖枠Sn(n=1〜8)を上方向又は下方向に開口する順番を示している。織成順序は緯入れ回数に相当する。   The weave pattern WP stored in the control device C of the loom can be displayed on the display screen 32 configured by the touch panel method of the display device 30. The weaving pattern WP shows the kite frame Sn (n = 1 to 8) (shown by eight kite frames often used in looms) on the horizontal axis, and the weaving order of the weaving pattern WP on the vertical axis, that is, The order of opening the eaves frame Sn (n = 1 to 8) upward or downward is shown. The weaving order corresponds to the number of weft insertions.

図の例では織成順序が8回の緯入れで織り柄パターンWPの1サイクルが終了することを示している。また、織り柄パターンWPの○印の織り柄指令記号33は綜絖枠Sn(n=1〜8)のいずれかを上方向へ開口する指令であることを示し、●印の織り柄指令記号34は綜絖枠Sn(n=1〜8)のいずれかを下方向へ開口する指令であることを示す。   In the example shown in the figure, one cycle of the weaving pattern WP is completed when the weaving order is 8 times. Further, the woven pattern command symbol 33 with a circle mark in the woven pattern WP indicates that the hook frame Sn (n = 1 to 8) is opened upward, and the woven pattern command symbol 34 with a mark ● is displayed. Indicates a command to open any one of the eaves frames Sn (n = 1 to 8) downward.

例えば、織成順序1では、綜絖枠S1には下方向への開口指令が出され、綜絖枠S2〜S8には上方向への開口指令が出される。同様にして各織成順序で綜絖枠Sn(n=1〜8)の開口指令が出され、織成順序8では、綜絖枠S1〜S6に上方向への開口指令が出され、綜絖枠S7、S8に下方向への開口指令が出されて織り柄パターンWPの1サイクルが終了する。以降、織り柄パターンWPのサイクルが繰り返され、織り柄パターンWPに対応した織り柄が織機上の織物表面に現れる表織りの製織が行われる。   For example, in the weaving order 1, a downward opening command is issued to the collar frame S1, and an upward opening command is issued to the collar frames S2 to S8. Similarly, in each weaving order, an opening command for the eaves frame Sn (n = 1 to 8) is issued. In the weaving order 8, an upward opening command is issued for the eaves frames S1 to S6, and the eaves frame S7. , A downward opening command is issued in S8, and one cycle of the weave pattern WP is completed. Thereafter, the cycle of the weaving pattern WP is repeated, and weaving of the front weaving is performed in which the weaving pattern corresponding to the weaving pattern WP appears on the surface of the fabric on the loom.

表示画面32には、織り柄パターンWPの他、織り柄パターンWPのスクロールボタン35及び表織りボタン36、裏織りボタン37が表示される。表織りボタン36を押すと、図2のように織り柄パターンWPが表示される。裏織りボタン37をタッチすると、織機の制御装置Cが下記のように作動し、図4に示す裏織り用の織り柄パターンWR2(以下、単に織り柄パターンWR2と称する)が表示される。なお、裏織り用の織り柄パターンWR2は表示画面32に表示しなくてもよい。また、図3に示す織り柄パターンWR1は、織り柄パターンWPから織り柄パターンWR2に至る中間の段階を説明用に示したものである(以下、単に中間の織り柄パターンWR1と称する)。   On the display screen 32, a scroll button 35, a front weave button 36, and a back weave button 37 of the weave pattern WP are displayed in addition to the weave pattern WP. When the front weaving button 36 is pressed, a weave pattern WP is displayed as shown in FIG. When the back weaving button 37 is touched, the control device C of the loom operates as follows, and the back weaving pattern WR2 (hereinafter simply referred to as the weaving pattern WR2) shown in FIG. 4 is displayed. The weave pattern WR2 for back weaving may not be displayed on the display screen 32. Further, the interwoven pattern WR1 shown in FIG. 3 shows an intermediate stage from the interwoven pattern WP to the interwoven pattern WR2 for explanation (hereinafter simply referred to as an intermediate interwoven pattern WR1).

裏織りボタン37を押すことにより生じる指令信号は、織機の制御装置Cに伝達され、織機の制御装置Cは記憶部ROMに記憶されている織り柄パターンWR2の作成プログラムを読み出し、実行する。作成プログラムは次の2つの過程を含む。即ち、1つは、図2に示した各織り柄指令記号33及び34を反転してそれぞれ図3に示すように●印の織り柄指令記号38及び○印の織り柄指令記号39に変更し、織り柄パターンWPを反転した中間の織り柄パターンWR1を生成する過程である。他の1つは、図3の織り柄パターンWR1において、各綜絖枠Sn(n=1〜4)の織成順序1〜8を逆転し、図4に示す裏織り用の織り柄パターンWR2を生成する過程である。   A command signal generated by pressing the back weave button 37 is transmitted to the control device C of the loom, and the control device C of the loom reads and executes a creation program for the weaving pattern WR2 stored in the storage unit ROM. The creation program includes the following two processes. That is, the first is to invert each of the weaving pattern command symbols 33 and 34 shown in FIG. 2 to change to a weaving pattern command symbol 38 marked with ● and a weaving pattern command symbol 39 marked with ○ as shown in FIG. This is a process of generating an intermediate weave pattern WR1 obtained by inverting the weave pattern WP. The other one is that the weaving patterns 1 to 8 of the rib frames Sn (n = 1 to 4) are reversed in the weaving pattern WR1 of FIG. 3, and the weaving pattern WR2 for back weaving shown in FIG. It is a process of generating.

図に示した第1の実施形態では、まず図3のように、織り柄パターンWPの織り柄指令記号33及び34を反転する過程を実行し、次に図3の中間織り柄パターンWR1の織成順序を逆転する過程を実行して図4の織り柄パターンWR2を生成するという順序でプログラムが作成されている。このプログラムにおける2つの過程の実行順序は本実施形態と逆の順序で実行するようにプログラム変更しても同一の結果を得ることができる。   In the first embodiment shown in the figure, first, as shown in FIG. 3, the process of inverting the weaving pattern command symbols 33 and 34 of the weaving pattern WP is executed, and then the weaving of the intermediate weaving pattern WR1 of FIG. The program is created in the order of executing the process of reversing the generation order to generate the woven pattern WR2 of FIG. Even if the program is changed so that the execution order of the two processes in this program is executed in the reverse order of the present embodiment, the same result can be obtained.

なお、織り柄パターンWR2の生成は、図3及び図4において説明の便宜上、1サイクルのデータ全てについて実行してから製織が行われるような形で示しているが、実際の製織では運転中に都度前記2つの過程を実行するようにプログラムされている。   The generation of the weaving pattern WR2 is shown in the form in which weaving is performed after all the data of one cycle is executed in FIGS. 3 and 4 for convenience of explanation. It is programmed to execute the two processes each time.

即ち、最初に図4の織成順序1を生成して織り柄指令を発信し、次に織成順序2を生成して織り柄指令を発信するというように順次織り柄パターンの生成と織り柄指令の発信を行うようにプログラムされている。但し、織機の制御装置Cから開口指令が発信され、電子開口装置が実際に作動するまでにタイムラグがあるため、例えば織成順序3回分の織り柄パターンを常時生成しておくような方法が取られている。また本実施例において、生成された裏織り用の織り柄パターンWR2は、例えばアップダウンカウンター(図示せず)等を用いて一時記憶と削除を行うようにし、恒久的な保存はしない構成である。   That is, the generation of the weaving pattern 1 and the weaving pattern, such as first generating the weaving order 1 and transmitting the weaving pattern command, and then generating the weaving order 2 and transmitting the weaving pattern command. It is programmed to send a command. However, since there is a time lag until the opening command is transmitted from the control device C of the loom and the electronic opening device is actually operated, for example, a method of constantly generating a weave pattern for three weaving sequences is used. It has been. Further, in the present embodiment, the generated weave pattern WR2 for back weaving is configured to be temporarily stored and deleted using, for example, an up / down counter (not shown), and not permanently stored. .

以上のように構成された第1の実施形態の作用を以下に説明する。
織機において、通常の製織は表織りボタン36が押された状態にしておき、図2の織り柄パターンWPに基づいて織機の制御装置Cから電子開口装置の開口制御装置C1に開口指令信号が出されると、開口制御装置C1から各駆動モータMn(n=1〜4)に駆動指令が出され、各綜絖枠Sn(n=1〜4)による経糸開口運動が行われる。
The operation of the first embodiment configured as described above will be described below.
In the loom, normal weaving is performed with the front weaving button 36 pressed, and an opening command signal is output from the loom control device C to the opening control device C1 of the electronic opening device based on the weaving pattern WP in FIG. Then, a drive command is issued from the opening control device C1 to each drive motor Mn (n = 1 to 4), and a warp opening motion is performed by each reed frame Sn (n = 1 to 4).

織り柄の汚れや傷付きの恐れがある織物や多数の綜絖枠が同時期に上方へ開口され、負荷が大きくなるような織物の製織が必要になった場合、裏織りボタン37を押すことにより表織りから裏織りへ切り換えられる。裏織りボタン37による裏織りへの変更指令は織機の制御装置Cに送信される。   If weaving of a weaving pattern that has a risk of soiling or scratching or a large number of reeds is opened upward at the same time, and weaving of the weaving that increases the load is necessary, press the back weaving button 37 Switch from front to back weaving. A change command to the back weaving by the back weaving button 37 is transmitted to the control device C of the loom.

織機の制御装置Cは記憶部ROMに記憶されている裏織り用のプログラムを読み出し、記憶されている図2の織り柄パターンWPを基に各織り柄指令記号33及び34を図3の織り柄指令記号38及び39のように反転する過程を実行する。続いて、図3の織り柄パターンWR1について織成順序を逆転し、図4の織り柄パターンWR2を生成し、一時的に記憶させておく。   The loom control device C reads the back weaving program stored in the storage unit ROM, and sets the weaving pattern command symbols 33 and 34 based on the stored weaving pattern pattern WP in FIG. The inversion process is executed as in command symbols 38 and 39. Subsequently, the weaving order is reversed for the woven pattern WR1 in FIG. 3, and the woven pattern WR2 in FIG. 4 is generated and temporarily stored.

このように生成された織り柄パターンWR2について、織機の制御装置Cはまず織成順序1の織り柄指令に基づく開口指令を開口制御装置C1に送信し、以後、織成順序1の織り柄指令に基づく開口指令を送信するまで順番に開口指令を発信し、織り柄の1サイクルが終了する。また、生成された織成順序1や織成順序2等の古い織り柄指令記号は設定された数の新しい織成順序の織り柄指令が生成されると順次削除されていく。その後は上記の動作を繰り返し、製織が行われる。
なお、裏織りを中止する場合は表織りボタン36を押すことによって裏織りから表織りに切り換えられ、表織りの指令信号が織機の制御装置Cに発信される。以後は表織りが行われる。
For the weaving pattern WR2 generated in this way, the loom control device C first transmits an opening command based on the weaving order 1 weaving pattern command to the opening control device C1, and thereafter the weaving order 1 weaving pattern command. The opening command is transmitted in order until the opening command based on is transmitted, and one cycle of the weave pattern is completed. In addition, old weaving pattern command symbols such as the weaving order 1 and the weaving order 2 that have been generated are sequentially deleted when a set number of new weaving pattern commands are generated. Thereafter, the above operation is repeated and weaving is performed.
In order to cancel the back weaving, the front weaving button 36 is pressed to switch from the back weaving to the front weaving, and a front weaving command signal is transmitted to the control device C of the loom. After that, surface weaving is performed.

前記した本願発明の第1の実施形態は、以下の作用効果が得られる。
(1)簡単な方法及び装置により、各綜絖枠Snに経糸Yを通し直すという煩雑な作業を必要とせずに表織り時の織り柄と同一の織り柄を裏織りで製織することができる。
(2)表示装置30の裏織りボタン37を押すだけで裏織り指令信号が発信され、織機の制御装置Cは記憶されている裏織り用プログラムを読み出し、実行するので、作業者は特別な操作や作業を行う必要が無く、簡単に裏織りを行うことができる。
The above-described first embodiment of the present invention has the following effects.
(1) By the simple method and apparatus, the same weave pattern as the front weaving pattern can be woven with the back weaving without requiring the troublesome work of passing the warp Y through each rib frame Sn.
(2) The back weaving command signal is transmitted simply by pressing the back weaving button 37 of the display device 30, and the control device C of the loom reads and executes the stored back weaving program. There is no need to carry out or work, and the back weaving can be performed easily.

(3)表織り用の織り柄パターンWPを記憶させておくだけで裏織り用の織り柄パターンWR2を都度生成することができ、表織り用と裏織り用の両方の織り柄パターンを記憶するための容量を必要とせず、装置を簡略化できる。
(4)表織りも裏織りも同一の織り柄を製織できるため、裏織りをするか否かは、織機の制御装置Cに記憶されている表織り用の織り柄パターンWPを表示画面に表示するだけで判断することができる。
(3) The woven pattern WR2 for back weaving can be generated each time by simply storing the woven pattern WP for front weaving, and stores both the weaving pattern patterns for front and back weaving. Therefore, the apparatus can be simplified.
(4) Since the same weave pattern can be woven for both the front and back weaves, whether or not to perform the back weave is displayed on the display screen with the weaving pattern WP for front weaving stored in the control device C of the loom Just make a decision.

(第2の実施形態)
図1〜図4を利用して第2の実施形態を説明する。なお、第1の実施形態と同一の構成については詳細な説明を省略する。
(Second Embodiment)
A second embodiment will be described with reference to FIGS. Detailed description of the same configuration as that of the first embodiment will be omitted.

第2の実施形態は、裏織りを行う方法の一部変更に関するものである。記憶されている織り柄パターンWPは、実際の織物の場合、綜絖枠数が16枚であったり、1サイクルの織成順序数が緯入れ回数数十回とか数百回に及ぶものもあり、織機に備えられている表示装置30では充分に表しきれない場合も多々有る。   The second embodiment relates to a partial change in the method of performing the back weaving. In the case of an actual woven fabric, the stored woven pattern WP has 16 sash frames, or the number of weaving orders in one cycle reaches several tens or hundreds of weft insertions. There are many cases where the display device 30 provided in the loom cannot be fully represented.

そこで、第1の実施形態のように表織りボタン36を押して図2のように織り柄パターンWPを表示装置30に表示して織り柄を確認するのではなく、裏織りを行う前に、表織りで織機を起動する。織り柄パターンWPを数サイクル分試織した時点で織機を停止する。試織により製織された織物は表織りであるため、織物の表面に織り柄が現れ、織り柄全体を見ることができる。従って、作業者は従来のように織り柄を確認するために織物を裏返す等の余分な作業を必要としないため、実際に製織された織り柄や織物の出来具合を容易に確認することができる。   Therefore, the front weaving button 36 is pressed as in the first embodiment and the weaving pattern WP is displayed on the display device 30 as shown in FIG. 2 to confirm the weaving pattern. Start the loom with weaving. When the weaving pattern WP is weaved for several cycles, the loom is stopped. Since the fabric woven by trial weaving is a surface weave, a weave pattern appears on the surface of the fabric, and the entire weave pattern can be seen. Therefore, the operator does not need extra work such as turning over the fabric in order to confirm the weaving pattern as in the prior art, so that the actual weaving pattern and the quality of the fabric can be easily confirmed. .

試織した織物が目的の織り柄に一致し、織物も他に問題が無いことを確認したら、表示装置30の裏織りボタン37を押し、織機を起動する。その後は、第1の実施形態と同様に織機の制御装置Cが裏織り用のプログラムを実行し、表織りと同一の織り柄を裏織りで製織することができる。   When it is confirmed that the weaved fabric matches the target weaving pattern and there are no other problems with the fabric, the back weaving button 37 of the display device 30 is pressed to start the loom. Thereafter, similarly to the first embodiment, the control device C of the loom executes the back weaving program, and the same weaving pattern as the front weaving can be woven with the back weaving.

第2の実施形態は、表織りと裏織りとをボタン1つで切り換え可能である点を利用し、作業者が作業しやすい表織りで織物の製織状態を簡単に確認することができるという特有の効果を有する。   The second embodiment uses the fact that it is possible to switch between front and back weaving with a single button, and it is possible to easily check the weaving state of the fabric with the front weaving that is easy for the operator to work. It has the effect of.

本願発明は、前記した各実施形態の構成に限定されるものではなく本願発明の趣旨の範囲内で種々の変更が可能であり、次のように実施することができる。   The present invention is not limited to the configuration of each of the embodiments described above, and various modifications are possible within the scope of the gist of the present invention, and can be implemented as follows.
