摘要:
An injection molding apparatus and method of fabricating a molded part are provided. The apparatus may include a barrel, a nozzle enclosing an end of the barrel and defining an opening in fluid communication with an inside of the barrel, and an extrusion screw positioned at least partially inside the barrel and rotatable relative to the barrel. The extrusion screw may include a screw tip. Relative axial movement between the barrel and the extrusion screw may open or close the opening of the nozzle to permit or prevent, respectively, material flow through the opening of the nozzle. The method may include clamping a mold, opening a nozzle, rotating the extrusion screw to pump a molten material into the mold until the mold is filled, closing the nozzle, and unclamping the mold to release a molded part.

摘要:
A material processing system has a plurality of material processing stations, one of which is a base material processing station. Material is directed to be processed serially through said plurality of processing stations in a given order to said base station. Such an arrangement is improved by providing that each of said plurality of processing stations and said base station comprises a separate data and control processor. There is a communication loop interconnecting the processors of said plurality of stations in said given order to the processor of said base station and interconnecting said processor of said base station to the processor of the first of said plurality of stations. A control signal is used to determine processing of material at each station. The processors of said plurality of stations each have means responsive to said control signal for executing each processing at each said station, and means responsive to a completion of each station processing for providing a completion signal to the next successive station along said communication loop. The system may be used in a document inserter.
摘要:
The invention relates to a method and a device for controlling a production cell for producing plastic injection-moulded parts, according to which the production cycle is defined and parameterised by the user. The invention is based on a component-oriented control system. Components can be, for example, the mould closure, the injection unit, the core puller, the handling appliances etc., which are virtually formed in the control system. According to the invention, machine cycles are designed, managed and run on the basis of behaviourally complete components, together forming a domain model, by means of a specialised domain language. In this way, an injection-moulding machine can be used and operated in a universal and simple manner. The components appear on the display screen or operating surface and are used by the user as the basis for the modelling of any cycles. Furthermore, a domain language is used for each problem area in the control system, in order to describe solutions and to automatically generate the program code therefrom.

A material processing system comprising a plurality of material processing stations and means for transporting articles to be processed serially through the processing stations in a given order, the improvement comprising a central processing station computer, a plurality of peripheral processing stations, each of the peripheral processing stations including a microprocessor, a first data channel serially interconnecting each of the peripheral processing station computers with the central processing station computer, a second data channel connecting each of the peripheral processing station computers directly with the central processing station computers, and a third data channel interconnecting each of the peripheral processing station computers with its next adjacent peripheral processing station computers, each of the channels performing a different data processing operation for controlling the serial processing for transporting articles.
摘要:
A remote controller can be provided on any apparatus that employs feedback control from a native controller to add functionality to the apparatus where the native controller is not capable of providing such functionality independently.
