Embodiment Construction

[0053] figure 1 The metal detection device 1 of the invention is shown equipped with three test devices 2A, 2B, 2C connected to the pneumatic control device 3 as symbolically indicated by the arrows.

[0054] The metal detection device 1 is designed to detect metal-contaminated products in vertical packaging applications, ie for inspecting products in flight before insertion into a sealed package. The device is designed with a minimum height to allow it to be installed, for example, in a confined space between the scale and the bag making machine.

[0055] The metal detection device 1 comprises a housing 11 having an inlet aperture 111 and an outlet aperture 112 which define inside the housing 11 a travel path along which the object 9 under inspection can move through the detection zone 100 . In order to mount the metal detection device 1 , the housing 11 is equipped with mounting means such as a mounting flange 115 and a mounting hole 116 .

Abstract

An apparatus (1) for detecting metal is equipped with at least one test device (2) with a non-metallic guide tube (21). Only a proximal end of the guide tube is connected to a pneumatic control unit (3). A distal end of the guide tube has at least one first ventilation port (211). The guide tube comprises a test article (7) which is movable back and forth between the proximal end and the distal end of the guide tube at least through a section of an electromagnetic field. The pneumatic control unit (13) can use air pressure to the proximal end of the guide tube (21) in order to drive the test article back and forth, or only in one direction if it is returned by gravitational force, and the air pressure is elevated above or reduced below the ambient pressure.

Description

technical field [0001] The invention relates to a metal detection device, a device for testing a metal detection device and a method for optimizing a metal detection device with a test device. Background technique [0002] Metal detection equipment is used to detect and reject unwanted metal contaminants. When properly installed and operated, it will help reduce metal contamination and improve food safety. The latest metal detector applications include a "balanced coil system" search head. Detectors of this design are capable of detecting all types of metal contamination including ferrous, non-ferrous and stainless steel in a wide variety of products such as fresh and frozen. [0003] The metal detection apparatus typically comprises a metal housing having inlet and outlet apertures of different or equal sized cross-sectional areas defining a travel path inside the housing along which the object under inspection moves. [0004] Metal detection equipment operating on the "...
