〔産業上の利用分野〕
この発明は、電動ミシンを制御するミシン制御装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sewing machine control device for controlling an electric sewing machine.
一般に、工業用ミシンは足踏みスイッチなどによってモ

われるようになっている。そして、補正縫いまたは一針
縫いなどを行なうため、ミシンヘッドに補正縫いスイッ
チが設けられている。In general, industrial sewing machines use a foot switch or the like to rotate a motor, and the power is used to perform sewing. A correction stitch switch is provided on the sewing machine head in order to perform correction stitches or single-stitch stitches.
このような従来の装置において、縫製位置を変更するた
め、布の平行移動または回転移動を行なうときは、モー
タの回転を止めてからその作業を行なっているが、この
とき補正縫いスイッチに布または作業者の手が触れると
このスイッチがオンとなシ、補正縫いが開始されてしま
い、危険であるという欠点があった。In such conventional devices, when moving the cloth in parallel or rotationally in order to change the sewing position, the motor rotation is stopped first. When touched by a worker's hand, this switch turns on and correction stitching begins, which is dangerous.
この発明はかかる問題点を解決するためになされたもの
で、安全なミシン制御装置を得ることを目的とする。The present invention was made to solve these problems, and an object of the present invention is to provide a safe sewing machine control device.
このような欠点を解決するためにこの発明は、布押えの
上昇時はモータの回転駆動指令を無効にするための手段
を設けたものである。In order to solve these drawbacks, the present invention provides means for invalidating the rotational drive command of the motor when the presser foot is raised.
布押えの上昇時は誤まって補正縫いスイッチをオンにし
てもモータが回転駆動さ九ない。Even if the correction stitch switch is turned on by mistake when the presser foot is raised, the motor will not rotate.

ベルの信号が供給されているときは端子７ｄから「０」
レベルの信号が送出されるようになっている。In the figure, 1 is a correction stitch switch, 2 is a presser foot lifting switch for controlling the lifting of the presser foot when turned on, 3 is a foot switch, 4 and 5 are logic circuits, 6 is an inverter, and 7
is a control unit, 8 is a transistor, 9 Otori to 9c are resistors, 10
1 is a solenoid for controlling the rise and fall of the presser foot, and 11 is an OR circuit. The control section 7 sends out a correction sewing command signal from the terminal 1b when a "0" level signal is supplied to the terminal 7a, and sends a "correction sewing command signal" from the terminal 7d when a "0" level signal is supplied to the terminal 7c. 1'' level hookup signal is transmitted. Also, when the rlJ level signal is supplied to the terminal 7c, "0" is output from the terminal 7d.
level signals are sent out.
このように構成さｎた装置の動作は次のとおシである。The operation of the device configured as described above is as follows.
押え上げスイッチ２がオフのとき、すなわち布押えが下
降しているとき、制御部７の端子７ｃは「ｌ」レベルと
なっているので、端子７ｄから「０」レベルの信号が送
出されている。このとき補正縫いスイッチ１をオンにす
ると論理回路４は「０」レベルの信号を送出するので、
制御部７の端子７ｂから図示しない駆動部に補正縫い指
令信号が送出さｎ１補正縫いが行なわれる。When the presser foot lifting switch 2 is off, that is, when the presser foot is lowered, the terminal 7c of the control unit 7 is at the "L" level, so a signal at the "0" level is sent from the terminal 7d. . At this time, when the correction stitching switch 1 is turned on, the logic circuit 4 sends out a "0" level signal, so
A correction sewing command signal is sent from the terminal 7b of the control section 7 to a drive section (not shown), and n1 correction stitching is performed.

る。この状態で布は布押えによる押圧が解除さｎるので
、作業者は布を任意の位置に移動または回転させること
ができる。When the cloth is moved or rotated to change the sewing location, when the presser foot lifter switch 2 is turned on, a signal at the crcrOj level is supplied to the terminal 7 of the control section, and a signal at the "l" level is sent from the terminal 7d. When the transistor 8 is turned on, the solenoid 10 is driven and the presser foot is raised. In this state, the cloth is no longer pressed by the presser foot, so the operator can move or rotate the cloth to any desired position.
この時、布または作業者の手が誤まって補正縫いスイツ

論理回路４の他方の端子に供給されている。このため、
補正縫いスイッチ１から送出さｎている「０」レベルの
信号は制御部７に供給されないので、誤まって補正縫い
スイッチ１がオンとなっても、補正縫いの行なわれる危
険はない。At this time, if the fabric or the worker's hand accidentally touches the compensation stitch switch, 1, a "0" level signal, which is a command to perform compensation stitches, is sent from that switch to one terminal of the logic circuit 4. Supplied. At this time, since the control section 1 is sending out a signal at the "1" level from the terminal 7d, this signal is supplied to the other terminal of the logic circuit 4. For this reason,
Since the "0" level signal sent from the compensation stitching switch 1 is not supplied to the control section 7, there is no danger that compensation stitching will be performed even if the compensation stitching switch 1 is turned on by mistake.
一方、ミシンは針上げまたは糸切シ、中立、増速の制御

チ３から送出さｎた「０」レベルの信号がインバータ６
で反転され、論理回路４に「１」レベルの信号を供給す
るので、補正縫いスイッチ１が誤まってオンとなっても
、その信号は制御部７に伝えられない。On the other hand, the sewing machine selects needle raise or thread trim, neutral, or speed increase control by changing the operating direction of the foot switch. It is also conceivable that the correction stitching switch 1 may be turned on by mistake while the signal tube is sending out the signal at the "0" level. At this time, the "0" level signal sent from the foot switch 3 is sent to the inverter 6.
Since the signal is inverted and a "1" level signal is supplied to the logic circuit 4, even if the correction stitch switch 1 is accidentally turned on, the signal will not be transmitted to the control section 7.
また、インバータ６の信号は論理回路５にも供給するよ
うにして、足踏みスイッチ３が踏まれているときは布押
えの上昇はできないようにしている。Further, the signal from the inverter 6 is also supplied to the logic circuit 5, so that the presser foot cannot be raised when the foot switch 3 is depressed.

を有する。Although the above embodiment is an example in which the process is performed electrically, the process may also be performed mechanically in conjunction with the presser foot. [Effects of the Invention] As explained above, the present invention has a method in which the presser foot lifting switch is Since the rotation control of the motor is prohibited when the presser foot is being controlled to rise, it is possible to maintain work safety.
