What Is a Needle Detector?
A needle detector is used to detect broken needles, staples, iron needles, nails, and broken pieces that have been mixed in with various textile and industrial products.
When a foreign object is detected, a lamp and electronic buzzer alerts the operator.
The equipment ranges from compact, lightweight, and easy-to-handle handheld types, to tabletop types that require less space for efficient inspection, to conveyor types that simplify inspection work after mass production, thereby improving productivity.
The conveyor type is available in a wide variety of types, so it can be selected according to the object and work environment.
Applications of Needle Detectors
Needle detectors are used in a wide range of fields, such as apparel, food, recycling, medicine, medical, sewing, logistics, baby products, sporting goods, chemical, security, and crime prevention.
Examples of applications are as follows:
- Needle inspection of ties, stockings, and other small products
- Needle inspection of apparel products such as women's, children's, and men's clothing, including forgotten needles
- Detection of needles, nails, and other iron fragments mixed in with pharmaceutical products
- Medical detection such as hairpin removal
- Detection for weapons, security, and safety
- Partial detection of needles, broken needles, and iron pieces mixed in sewing products
- Detection of needles and iron fragments in textiles, carpets, felts, non-woven fabrics, and other textile products
- Detection of iron needles mixed in industrial materials such as rubber, plastic raw materials, sheets, boards, cardboard, etc.
- Inspection of baggage and parcels such as bags
- Detection of small iron pieces such as bolts, nuts, tacks, needles, mixed in products
Principle of Needle Detectors
Needle detectors use the electromagnetic induction method.
When a permanent magnet and a search coil are installed in the sensor head, magnetic lines of force are generated between the permanent magnet and the detection coil.
When a magnetic object such as a needle approaches the magnetic field lines, the magnetic field lines deform in response to the magnetic material attached to the magnet, causing an electric current to flow.
The search coil detects the current and sends the information to the processing circuit, which sounds an alarm or stops the conveyor.
Basically, it detects magnetic objects, but some of them may also react to dust, dirt, and non-magnetic metals.
Also, since the detection response may differ depending on the directionality of the needle, some devices are equipped with two sensor heads at different angles or with a twice-angled needle detection to increase the level of sensitivity.
Some instruments use a large color LCD touch panel, some can record inspection history as data, and some can print out inspection results using a printer.
They can be equipped with a lock function, a function to set sensitivity levels by stages, a conveyor speed adjustment function, etc. Select a device that is easy to use, highly reliable, and has few malfunctions.
