本発明は、織機の積極的な電動送り出し装置に
関し、特に織布の停止段を解消する手段に係る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a positive electric unwinding device for a weaving loom, and more particularly to a means for eliminating the stop stage of the woven fabric.
緯入れ不正時に不良糸が抜き取られると、織口
は、その分だけ前進することになる。したがつて
その後の運転再開に際し、織口を正規の位置まで
後退させる必要があるが、従来この操作は、巻取
り装置および送り出し装置を操作し、織口を正規
の位置に合わせるという複雑で、熟練を要する作
業により行なわれている。 If a defective yarn is pulled out during incorrect weft insertion, the weave will move forward by that amount. Therefore, when restarting operation afterwards, it is necessary to move the cloth back to its normal position, but conventionally this operation has been complicated, requiring the operator to operate the winding device and the feeding device to align the cloth cloth to its normal position. It is performed by work that requires skill.
また織口が正規の位置に調整されたとしても、
織機の停止による経糸の伸びや起動時のおさ打ち
スピードの不足などから、織布に織段が発生する
こともある。この停止段は、高速の流体噴射式織
機において、特に顕著に現われる。 Also, even if the weaving opening is adjusted to the correct position,
Weaving steps may occur in the woven fabric due to elongation of the warp threads when the loom stops, or due to insufficient beating speed when starting up the loom. This stop stage is particularly noticeable in high-speed fluid jet looms.
このような停止段は、キツクバツク型式のダン
サーロールをエアシリンダなどの駆動手段で一時
的に後退させ、織布の織口を正規の位置に合わせ
るとともに、経糸の張力を制御することによつ
て、ある程度解決できる。しかしその解決手段に
よると下記の欠点がある。 This kind of stop stage is achieved by temporarily retracting the kickback type dancer roll using a driving means such as an air cylinder, aligning the weaving edge of the fabric to the proper position, and controlling the tension of the warp threads. It can be solved to some extent. However, this solution has the following drawbacks.
(1) 起動時に張力が一時点に高まるため、張力制
御系の送り出し装置は、これを補正する方向に
働き、キツクバツク効果を低下させてしまう。
また、キツクバツクの解除時に、一時的に経糸
張力が低下するため、大きな張力変動が現わ
れ、制御系に乱調が起き易く、キツクバツク効
果は、かえつて逆に作用し、停止段を発生させ
ることさえある。(1) Since the tension increases at a certain point during startup, the tension control system's delivery device works to compensate for this, reducing the kickback effect.
In addition, when the snapback is released, the warp tension temporarily decreases, resulting in large tension fluctuations that tend to cause disturbances in the control system, and the snapback effect may even work in the opposite direction, causing a stop stage. .
(2) キツクバツク方式のダンサーロールを後退さ
せるために、特別な駆動装置および制御装置が
必要であり、装置が複雑となる。(2) A special drive device and control device are required to retract the kickback dancer roll, making the device complicated.
したがつて、本発明の目的は、電動送り出し装
置の電気的な回転制御により、停止時の織口の位
置調整や、起動時の過渡的なおさ打ちの強弱を自
動的に調整できる電動送り出し装置を提供する点
にある。 Therefore, it is an object of the present invention to provide an electric feed-out device that can automatically adjust the position of the weaving cloth when stopped and the intensity of the transient beating during startup by electrically controlling the rotation of the electric feed-out device. It is in the point of providing.
さて第１図は、本発明の基本的な思想を織口
１、緯糸２および経糸３の関係で示している。不
正な緯糸２が例えば１本抜き取られると、織口１
は、正規の位置から１ピツク分の移動量L0だけ
前進する。したがつて織口位置の調整は、経糸３
を移動量L0だけ引き戻すことにより行なわれる。
またこの停止中の経糸張力により経糸３が伸びる
ため、織口１は、さらに前進方向に移動量L1だ
け変位する。したがつて起動時には、経糸３の伸
び分を予め見込んで、補償する必要がある。さら
に織機の運転再開時には、織機の回転速度が一定
の傾斜をもつて立ち上がるため、運転再開直後の
数回にわたつておさ打ち力が弱く、そのため織口
１が後退し、その結果ひま段が発生するため、こ
れも補償する必要がある。 Now, FIG. 1 shows the basic idea of the present invention in terms of the relationship among the weft 1, weft 2, and warp 3. For example, if one illegal weft thread 2 is pulled out, the weft opening 1
moves forward by the amount of movement L 0 corresponding to one pick from the normal position. Therefore, the adjustment of the weaving position is done by warp 3.
This is done by pulling back by the amount of movement L0 .
Furthermore, since the warp threads 3 are elongated due to the warp thread tension during this stop, the cloth opening 1 is further displaced in the forward direction by an amount of movement L1 . Therefore, at the time of starting, it is necessary to anticipate and compensate for the elongation of the warp threads 3 in advance. Furthermore, when the loom resumes operation, the rotational speed of the loom rises at a certain slope, so the beating force is weak several times immediately after the loom resumes operation, which causes the weaving head 1 to move backwards, resulting in the rows being shortened. This also needs to be compensated for.
そこで本発明は、織口１の位置合わせ後におい
て、織機の再起動直前に、打ち込み密度と送り出
しビームの巻径とによつて決まる適正量だけ、送
り出しを逆転することにより、織口１を運転再開
時のおさ打ち位置に合わせ、同時に経糸張力の大
きな変動を抑えるようにしている。 Therefore, the present invention operates the weave 1 by reversing the delivery by an appropriate amount determined by the driving density and the winding diameter of the delivery beam immediately before restarting the loom after positioning the weave 1. This is done to match the reshaping position when restarting, and at the same time to suppress large fluctuations in warp tension.
ところが織口１が正規の位置よりさらに後退し
ているため、そのまま運転を継続すると、厚段と
なる恐れがある。 However, since the cloth opening 1 is further retreated from its normal position, if the operation is continued as it is, there is a risk that the cloth will become thick.
そこで本発明は、織機の運転再開後に、一定期
間にわたつて送り出しモータを過電圧により駆動
し、経糸３の送りを助長し、厚段の発生を未然に
防止するようにしている。 Therefore, in the present invention, after restarting the operation of the loom, the feed motor is driven by overvoltage for a certain period of time to promote feeding of the warp threads 3 and prevent the occurrence of thick steps.
以下、本発明を図に示す一実施例にもとづいて
具体的に説明する。 Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

The fabric passes from the delivery beam 5 to the tension roll 6, and is wound up as a woven fabric onto the winding beam 9 via rolls 8a, 8b, and 8c, while forming the thread 7 and the weave 1. The delivery beam 5 is forcibly driven by a variable speed delivery motor 12, and the roll 8b is driven by a driving motor 10 of the loom.

定の時間だけオンとなる。 Next, FIG. 3 shows the electric feeding device 11 of the present invention.
It shows. This electric feeding device 11 has a winding diameter detecting device 13 in relation to a feeding motor 12.
It is composed of a motor drive device 14, a reverse rotation correction section 15, and a start correction section 16. Winding diameter detection device 1
3 detects the winding diameter of the warp threads 3 on the sending beam 5 and generates a speed signal S V that is inversely proportional to the winding diameter;
This is sent to the motor drive device 14 via a regulator 17, normally closed contacts 18, 37, and amplifiers 19, 20. The motor drive device 14 also includes a drive control circuit 21, a tachometer generator 22, and a contact point 2.
3, 24, and 25, and the drive control circuit 21 drives the feed motor 12 at a speed proportional to the input voltage, that is, the voltage such as the speed signal S V. Controlling to target speed. The feed motor 12 rotates in the forward direction when the input voltage is positive, and rotates in the reverse direction when the input voltage is negative. The contact 23 operates when the loom 4 is running (forward rotation), the contact 24 operates when the loom 4 rotates in reverse, and the contact 25 is turned on for a certain period of time before the loom 4 starts operating.

It outputs S R and is constructed by combining contacts 27 and 28, an inverting amplifier 30, and a regulator 31. Parallel connected contacts 27, 28, inverting amplifier 30
and regulator 31 are connected in series between the output terminal of regulator 17 and the input terminal of amplifier 20. Further, the contacts 27 and 28 are connected to the contacts 24 and 2 mentioned above.
5 and each have an interlocking relationship.

ある。 Furthermore, the start correction section 16 outputs a transient start correction signal S S to the motor drive device 14 during normal rotation operation, and is connected to a contact 23 between the output end of the regulator 17 and the input end of the amplifier 20. Associated contacts 26, integrator 32, variable regulator 33, contacts 29, 38
are configured by connecting them in series. In addition, integrator 3
2 and the input of amplifier 20 are connected to ground 36 by regulators 34 and 35, respectively.

is in a stopped state.

る。 First, during reverse operation, the contact 24 of the motor drive device 14 is turned on at time t1 of reverse operation,
In conjunction with this, contacts 18 and 29 are turned off, and contact 27 is turned on. At this time, the speed signal S V of the winding diameter detection device 13 is inverted and amplified by the contact 27 and the inverting amplifier 30, and is further inverted and amplified by the regulator 31.
The motor drive device 1 is amplified by an amplifier 20.
Sent to 4. Here, since the speed signal S v is inversely proportional to the winding diameter of the sending beam 5,
The delivery motor 12 rotates in the reverse direction at a speed related to the winding diameter of the delivery beam 5. This reversal command is performed only for an artificially necessary time.
In this way, the cloth opening 1 is pulled back by the amount of displacement advanced by the removal of the illegal yarn.

出力信号を与えない。 Next, when restarting operation, first turn on the feed motor 1.
2 is started at a start-up time t 2 , and the drive motor 10 of the loom 4 is started at a subsequent start-up time t 3 . That is, at the starting point t2 , the contact 25 is turned on, and in conjunction with this, the contact 28 is turned on for a certain period of time. Therefore, the speed signal S V is inverted by the inverting amplifier 30 via the contact point 28, and sent to the motor drive device 14 as a negative reverse rotation correction signal S R to temporarily give a command in the reverse direction. Negative reversal correction signal S R at this time
The peak value of is set by the adjuster 31. The amount of reversal corresponds to the elongation of the warp threads 3 due to the stoppage of the loom 4 and the amount of retraction of the sheath 1 due to insufficient rotation during startup. In this way, the cloth opening 1 is temporarily pulled back by an appropriate amount at the time of activation to avoid weaving flaws. Since the contacts 37 and 38 are in an off state during this certain period of time, the amplifier 19
And the startup correction section 16 does not give an output signal to the motor drive device 14.

２は、次の動作に備えて、再び充電されることに
なる。 At starting time t3 after a certain period of time, the contact 23 is turned on, and in conjunction with this, the contacts 37 and 38 are turned on, and at the same time, the contacts 25 and 28 are turned off. In this way, the reverse rotation correction section 15 is in a state where it does not take in the speed signal S V , but the amplifier 19 and the start correction section 16
Be able to participate in 4. The integrator 32 of the startup correction section 16 stores a constant charge proportional to the speed signal S V , but this charge is stored at the time of startup.
Variable regulator 3 as starting correction signal S S from t 3
3. It is added to the amplified speed signal S v via contacts 29 and 38, and applied to the input terminal of the amplifier 20. This start-up correction signal S S decreases exponentially and eventually reaches zero. In this way, the motor drive device 14 rotates the feed motor 12 in the reverse direction for a certain period of time from the start time t2 , then rapidly increases the speed in the forward rotation direction at the start time t3 of the loom 4, and then detects the winding diameter. Device 1
The feed motor 12 is driven at the speed given by the speed signal S V of No. 3. The transient start correction signal S S of the start correction section 16 causes the feed-out motor 12 to be adjusted in response to the amount by which the weaving cloth 1 is pulled back due to reversal between the start time t 2 and the start time t 3 of the loom 4. It is made to rise quickly at startup, and the reeding force is compensated to be equal to the reeding force at steady state. Therefore, the occurrence of steps can be prevented. Moreover, the charging voltage of the integrator 32 is always proportional to the voltage value of the speed signal S V , and the start correction signal S S from the integrator 32 is adjusted to an appropriate value by the variable regulator 33. Therefore, the transient feed-out amount at the initial stage of startup almost matches the amount of reversal at the time of startup of the reverse rotation correction section 15. Of course, in the subsequent steady operation state, the winding diameter detection device 13 detects the winding diameter of the sending beam 5, and sends a speed signal that is inversely proportional to the winding diameter.
Since S V is applied to the motor drive device 14 through amplifiers 19 and 20, the motor drive device 14 is
In response to the change in the winding diameter, the speed of the feed motor 12 is increased with a predetermined slope characteristic so as to follow the change. Then, at the time delay Δt after the startup correction signal S S becomes zero, that is, at time t 4 , the contact 29 turns off and the contact 26 turns on at the same time, so the integrator 3
2 will be charged again in preparation for the next operation.

きる。 In the present invention, since the reversal correction section temporarily drives the feed motor in the reverse direction immediately before starting the loom, it is possible to correct the displacement of the weaving edge position due to elongation of the warp yarns and the displacement of the reeling position due to insufficient rotation speed. After the loom resumes operation, the start correction section transiently increases the speed of the feed motor for a certain period of time, so the influence of changes in the beating force at the time of start-up can be prevented, thus improving the quality of the woven fabric. The occurrence of weaving steps can be effectively prevented.
