Embodiment Construction

[0093] figure 1 and figure 2 A typical process valve is shown. However, the invention is not limited to this type of valve, but can also be used in other valves using electronically actuated auxiliary valves or main valves. In particular, the invention can be used in pilot-controlled process valves with a pneumatic main valve and at least one pilot valve, in particular at least one solenoid valve. In other embodiments, the main valve is controlled directly.

[0094] The process valve shown schematically here has a pneumatic main valve 1 and a pilot valve 2 in the form of a solenoid valve, ie a solenoid valve.

[0095] The main valve 1 has a valve housing 10 with a control chamber 13 , a process pressure inlet channel 15 and a process pressure outlet channel 16 . The switching piston 12 is held displaceably in the valve housing 10 , the switching piston being sealed relative to the valve housing 10 by means of a high-pressure seal 14 . The switching piston is generally de...

Abstract

In a method for monitoring a blow-moulding device for producing a hollow body, the blow-moulding device comprises at least one process valve unit for feeding a process fluid into a preform of the hollow body under process pressure, wherein the process valve unit comprises at least one electrically operated valve. During a blow-moulding process, at least one value of an electric current of the electrically operated valve is detected. The method according to the invention and the device according to the invention allow early recognition of an ageing process of the process valves, in particular their pilot valves, and / or the recognition of the status of valve properties.

Description

technical field [0001] The invention relates to a method, a blow molding valve system and a computer program product for monitoring a blow molding installation for producing hollow bodies. [0002] A further invention relates to a method, a control system and a computer program product for monitoring a blow molding unit for producing hollow bodies. Background technique [0003] Hollow bodies made of thermoplastics, especially PP or PET bottles (PP=polypropylene; PET=polyethylene terephthalate), are usually produced by means of blow molding machines. For this purpose, the blank or parison is fed to the blow molding machine. The blank essentially already has a finished bottle head, by means of which the blank is held in the blow mold of the blow molding machine. The heated blank is inflated by blowing process gas, usually air, through the head of the bottle until said blank reaches its final shape. The shape is defined by surrounding forming tools. [0004] Insufflation is...
