【産業上の利用分野】[Industrial applications]

本考案は、吸着パットによってワークを吸着する真空吸着システムに関する。 The present invention relates to a vacuum suction system that sucks a work by a suction pad.

【0002】[0002]

【従来の技術】[Prior Art]

図1に示すように真空ポンプ1の吸込側を管路2で吸着パット3に連通し、そ の真空ポンプ1をACモータ4で駆動してワーク5に接した吸着パット3内を負 圧としてワーク5を吸着支持する真空吸着システムが知られている。 このような真空吸着システムにおいてはACモータ4とAC電源6の接続回路 7にスイッチ8を設け、このスイッチ8をON、OFFする真空圧力自動制御部 9を設け、前記AC電源6をトランス10、整流器11でDC電源12に接続し 、そのDC電源12を真空圧力自動制御部9に接続し、前記管路2に圧力センサ 13を設け、その検出した圧力信号を真空圧力自動制御部9に入力して設定真空 圧力となるとスイッチ8をOFFし、設定真空圧力より低下した時にスイッチ8 をONして吸着パット3内を常に設定真空圧力としてワーク5を確実に吸着支持 できるようにしている。 このようにすれば、吸着パッド3内の真空圧力が変化した時にのみACモータ 4が駆動して真空ポンプ1によって吸着パッド3内を設定真空圧力とし、設定真 空圧力の時にはACモータ4を停止できるからACモータ4を常時駆動しなくと も良い。 As shown in FIG. 1, the suction side of the vacuum pump 1 is connected to the suction pad 3 by a pipe line 2, and the vacuum pump 1 is driven by an AC motor 4 to make a negative pressure in the suction pad 3 in contact with the workpiece 5. A vacuum suction system that suction-supports the work 5 is known. In such a vacuum adsorption system, a switch 8 is provided in the connection circuit 7 between the AC motor 4 and the AC power supply 6, and a vacuum pressure automatic control unit 9 for turning the switch 8 ON and OFF is provided. The DC power source 12 is connected by the rectifier 11, the DC power source 12 is connected to the vacuum pressure automatic control unit 9, the pressure sensor 13 is provided in the pipe line 2, and the detected pressure signal is input to the vacuum pressure automatic control unit 9. Then, when the set vacuum pressure is reached, the switch 8 is turned off, and when the pressure is lower than the set vacuum pressure, the switch 8 is turned on so that the suction pad 3 is always set at the set vacuum pressure so that the workpiece 5 can be securely sucked and supported. By doing so, the AC motor 4 is driven only when the vacuum pressure in the suction pad 3 changes, and the vacuum pump 1 sets the suction pad 3 in the set vacuum pressure. When the set vacuum pressure is reached, the AC motor 4 is stopped. Since it is possible, it is not necessary to constantly drive the AC motor 4.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

かかる真空吸着システムであると停電、断線、欠相、ブレーカトリップ等のA C電源6に異常が発生してACモータ4を駆動できない場合や、ACモータ4の 焼付、過負荷等によってACモータ4が停止した場合に真空ポンプ1を回転でき ずに吸着パッド3内の圧力が低下してワーク5を落下させることがあって危険で ある。 With such a vacuum adsorption system, the AC motor 4 cannot be driven due to an abnormality in the AC power source 6 such as power failure, disconnection, open phase, breaker trip, etc., or the AC motor 4 is seized or overloaded. When the operation is stopped, the vacuum pump 1 cannot be rotated and the pressure in the suction pad 3 is lowered to drop the work 5, which is dangerous.

【0004】 そこで、本考案は前述の課題を解決できるようにした真空吸着システムを提供 することを目的とする。Therefore, an object of the present invention is to provide a vacuum adsorption system capable of solving the above-mentioned problems.

【0005】[0005]

【課題を解決するための手段】[Means for Solving the Problems]

AC電源6で駆動するACモータ4の出力側に真空ポンプ1を接続し、この真 空ポンプ1で吸着パット3内を真空にしてワーク5を吸着する真空吸着システム において、ワーク吸着時に前記吸着パット3内の真空度低下によりバッテリ電源 20で作動する警報装置23を設けて成る真空吸着システム。 In a vacuum suction system in which a vacuum pump 1 is connected to the output side of an AC motor 4 driven by an AC power source 6 and the vacuum pad 1 vacuumizes the suction pad 3 to suck a workpiece 5, the suction pad is sucked when the workpiece is sucked. A vacuum suction system provided with an alarm device 23 which is operated by a battery power source 20 when the degree of vacuum in 3 is lowered.

【0006】[0006]

【作 用】[Work]

ワーク5を吸着支持している状態でAC電源6の異常やACモータ4の異常に より吸着パット3内の真空度が低下した時に警報装置23が作動して作業者に知 らせるので、作業者は吸着パット3内の真空度低下によるワーク落下を未然に防 止できる。 When the vacuum level in the suction pad 3 is lowered due to an abnormality of the AC power supply 6 or an abnormality of the AC motor 4 while the work 5 is being suction-supported, the alarm device 23 is activated to notify the operator. The operator can prevent the work from dropping due to the decrease in the degree of vacuum in the suction pad 3.

【0007】[0007]

【実 施 例】【Example】

図2に示すようにAC電源6とは別にバッテリ電源20を設けると共に、真空 圧力自動制御部9用の圧力センサ13とは別に警報用の圧力センサ21を管路2 に設ける。 前記バッテリ電源20は回路22で真空度低下を警報する警報装置23に接続 し、この回路22にスイッチ24を設け、そのスイッチ24を前記圧力センサ2 1でON、OFFする。 すなわち、圧力センサ21は吸着パッド3内が設定真空圧力の時にはスイッチ 24をOFFし、吸着パッド3内の真空圧力が低下した時にスイッチ24をON する。 ここで、圧力センサ21がスイッチ24をONする時の真空圧力、つまり真空 度低下警報用設定圧Paは、前記真空圧力自動制御部9がスイッチ8をOFFす る時の真空圧力、つまり真空圧力自動制御用設定圧Pbよりも低く設定してある 。(Pa<Pb) また、真空圧力自動制御部9にはバッテリ電源20よりDC電源が供給される 。 As shown in FIG. 2, a battery power source 20 is provided separately from the AC power source 6, and a pressure sensor 21 for alarm is provided in the conduit 2 separately from the pressure sensor 13 for the vacuum pressure automatic control unit 9. The battery power source 20 is connected to an alarm device 23 for alarming a drop in the degree of vacuum in a circuit 22, a switch 24 is provided in this circuit 22, and the switch 24 is turned on and off by the pressure sensor 21. That is, the pressure sensor 21 turns off the switch 24 when the vacuum pressure inside the suction pad 3 is set, and turns on the switch 24 when the vacuum pressure inside the suction pad 3 decreases. Here, the vacuum pressure when the pressure sensor 21 turns on the switch 24, that is, the set pressure Pa for low vacuum warning is the vacuum pressure when the vacuum pressure automatic control unit 9 turns off the switch 8, that is, the vacuum pressure. It is set lower than the automatic control set pressure Pb. (Pa <Pb) Further, the vacuum pressure automatic control unit 9 is supplied with DC power from the battery power supply 20.

【0008】 以上のようであるから、吸着パット3でワーク5を吸着する時には吸着パッド 3内の真空圧力が前記圧力センサ21の作動する真空度低下警報用設定圧Paと なるまでの間スイッチ24がONして警報装置23が警報を発し、前記設定圧P a以上となるとスイッチ24がOFFして警報が停止する。 ワーク5を吸着した状態でAC電源の異常、ACモータ異常、真空圧力自動制 御部9の異常等により吸着パッド3の真空圧を前記真空圧力自動制御用設定圧P bを保持できずに前記真空度低下警報用設定圧Paまで低下するとスイッチ24 がONして警報を発するので、作業者は吸着パッド3内の真空圧が低下したこと を感知してワーク5が落下することを未然に防止できる。As described above, when the work piece 5 is sucked by the suction pad 3, the switch 24 is operated until the vacuum pressure in the suction pad 3 becomes the set pressure Pa for the vacuum degree reduction alarm at which the pressure sensor 21 operates. Is turned on and the alarm device 23 gives an alarm, and when the pressure exceeds the set pressure Pa, the switch 24 is turned off and the alarm is stopped. When the work 5 is sucked, the vacuum pressure of the suction pad 3 cannot be held at the vacuum pressure automatic control setting pressure Pb due to an abnormality of the AC power supply, an abnormality of the AC motor, an abnormality of the vacuum pressure automatic control unit 9, or the like. When the set pressure Pa for the low vacuum warning is reduced, the switch 24 is turned on and an alarm is issued, so that the worker can detect that the vacuum pressure in the suction pad 3 has decreased and prevent the work 5 from dropping. it can.

【考案の効果】[Effect of the device]

ワーク5を吸着支持している状態でAC電源6の異常やACモータ4の異常に より吸着パット3内の真空度が低下した時に警報装置23が作動して作業者に知 らせるので、作業者は吸着パット3内の真空度低下によるワーク落下を未然に防 止できる。 When the vacuum level in the suction pad 3 is lowered due to an abnormality of the AC power supply 6 or an abnormality of the AC motor 4 while the work 5 is being suction-supported, the alarm device 23 is activated to notify the operator. The operator can prevent the work from dropping due to the decrease in the degree of vacuum in the suction pad 3.
