摘要： The method and system are designed to detect whether a mobile piece or mobile pieces (8) of a mould (9) is/are in the correct or incorrect position, before proceeding to carry out the corresponding injection of the mould using the respective machine. for this reason, the application of a fluid has been provided for, preferably being compressed air, which will go through a channel (5-6) and through an opening (7) in the mould (9), in such a way that the fluid accesses the mobile piece (8) directly and causes the fluid to pass through a flow meter measuring device (1), firstly passing through a pressure regulation valve (3) and an air purification filter (4), in such a way that using a number of means (10) of the compressed air flow meter device (1), the signal captured by the flow measured is sent to the injection machine, so that the same can proceed to inject the mould (9) in the event of the correct position of the mobile piece (8) being detected or paralyse this injection process in the event of the incorrect position of this mobile piece (8) being detected.

摘要： The invention relates to a device and method for automatically monitoring repetitive operational sequences on injection molding machines and/or on handling units to injection molding machines, and for identifying abnormalities or disruptions with regard to the operational sequence. During normal production operation, the repetitive operational sequence of at least one partial process is provided, and a measurable quantity (1), which is influenced by the partial process, regarding the operational sequence monitoring is automatically recorded in short sampling intervals (2). The sampled values are compared with limit values (6) that were formed, by using an algorithm, from a multitude of previous sampled values of the same operational sequence. The sensitivity is automatically adapted to the process variations with regard to a decision to alert or terminate. This novel solution permits the carrying out of monitoring with the highest possible sensitivity, however, without a negative response, e.g. repetitive traveling motion, but also for operational sequences without moving parts such as the d.c. link voltage in converters or during controlled processes for monitoring a quantity that is not controlled.

摘要： A method for a hot runner injection molding system. The injection molding system has a plurality of melt conveying components defining a melt path from a melt source to a mold cavity and a mold housing. A force sensor or load cell is utilized between at least one melt conveying component of the system and the mold housing to measure a force generated due to thermal expansion of the melt conveying component during start-up and/or operation of the system and to provide an output to a receiving device. In an embodiment, once a sealing load or a predetermined preload force has been reached, an injection molding cycle may begin.

摘要： The invention relates to a method for operating an injection molding machine, particularly a method for securing tools of an injection molding machine. According to said method, a setpoint variable curve is determined along at least one section of a displacement path of a molding tool in a setpoint variable determination phase, and the injection molding machine is operated according to the determined setpoint variable curve in a subsequent operational phase. A preset curve of at least one initial variable is predefined, the molding tool is driven in accordance with the preset curve of the initial variable in a test run, at least one resulting value of the setpoint variable is measured and stored during the test run, and a setpoint variable curve is formed along the section of the displacement path from the measured values of the setpoint variable.

摘要： The invention relates to an electromechanical linear drive, in particular for an injection moulding machine, comprising an electric motor (1) with a hollow-shaft rotor (5), open on one side, with a subsequent screw gear (6) which converts the rotational movement of the hollow-shaft rotor into a linear movement. The hollow-shaft rotor is supported on the motor housing (2), at the end thereof closed by a end wall, such as to rotate, by means of a central bearing spigot (10) projecting axially from the end wall. According to the invention, an extremely stable-running, exactly central and fail-safe rotor bearing may be achieved with a simple construction and in an economical manner, whereby the bearing spigot is supported on the motor housing such as to rotate by means of at least two axially pre-tensioned, counter-rotating, individual bearings (11, 12), separated in the longitudinal direction and supporting longitudinal and transverse forces and, in the region of the open rotor end, an emergency running safety device (14, 15) for an eccentric rotor displacement is provided.

摘要： Zum Erkennen einer Blockierung eines bewegbaren Bauteils, insbesondere einer Formaufspannplatte, einer Spritzgießmaschine wird erfindungsgemäß vorgeschlagen, den Bewegungszustand des Bauteils fortlaufend zu überwachen und einen Antrieb zu deaktivieren, wenn keine Bewegung oder nur eine minimale Bewegung erfaßt wird.
Dazu kann beispielsweise Geschindigkeit des Bauteils direkt überwacht werden, oder die momentane Position des Bauteils wird zyklisch überwacht. Kommt es zu keiner Positionsänderung in aufeinderfolgenden Zyklen, wird auf eine Blockierung geschlossen.
Entsprechend kann man bei einer Lageregelung, bei der fortlaufend momentane Ist-Positionswerte mit momentanen Soll-Positionswerten verglichen werden, auf eine Blockierung schließen, wenn der Betrag der Differenz zwischen Ist- und Soll-Wert einen vorgegebenen Wert überschreitet.
Mittelbar kann der Bewegungszustand überwacht werden, in dem eine Betriebskenngröße eines Antriebsmotors, beispielsweise die Soll-Drehzahl im Vergleich mit der Ist-Drehzahl, überwacht wird.

摘要： An excessive load detection device for an injection molding machine capable of detecting an excessive load exerted on the injection screw when the screw is driven with resin remaining unmolten in the heating cylinder. An output torque of the servomotor for axially moving the screw is limited to a predetermined value by a torque limiter and the screw is driven to move forward in a direction of injection by a predetermined amount at a predetermined velocity. If reference time elapses before the axial motion of the set amount is completed or a position deviation exceeds a reference value, it is determined that the remaining resin has low fluidity to cause an excessive load on the screw and an alarm is issued. When the axial motion of the screw is completed without an alarm, the screw is moved backward and forward alternately predetermined times. A servomotor for rotating the screw is driven in the same manner to detect an excessive load on the screw. Since the excessive load on the screw is directly detected, the excessive load is securely detected.
摘要翻译：一种用于注射成型机的过载检测装置，其能够检测当加热缸中树脂未熔化时螺杆被驱动时施加在注射螺杆上的过大的负荷。用于轴向移动螺杆的伺服电动机的输出扭矩通过扭矩限制器被限制到预定值，并且螺杆被驱动以在预定方向上以预定速度在注射方向上向前移动预定量。如果在设定量的轴向运动完成或位置偏差超过参考值之前经过参考时间，则确定剩余树脂具有低流动性，导致螺钉上的过大负载并发出报警。当螺钉的轴向运动在没有报警的情况下完成时，螺杆将交替地向前和向前移动预定的次数。用于旋转螺钉的伺服电机以相同的方式被驱动以检测螺钉上的过大负载。由于直接检测到螺钉上的过大负荷，因此能够可靠地检测出过大的负荷。
