Germany'S Advanced Needle Detector Has Wide Application Scope.

Installation of detector probe

The 4022 needle detector manufactured by Protechna Herbst in Germany can be widely used in single plane, rib knitting machine, cotton wool machine, jacquard circular knitting machine and molding equipment.

It is understood that the needle sensor consists of an optical probe (which can be more than one) and a control unit 4022.

There are different types of looms.

At least one optical probe is used for each syringe.

If in a single displacement, all the work needles are not pushed to the same position, a plurality of optical probes must be connected to a syringe.

In this case, an optical probe is used for induction of a set of controlled knitting needles.

If all needle pins are pushed out at the same guide position (probably not yet supplied with yarn), then a single needle control program is available.

And other jacquard looms can be monitored by this device.

Monitoring is cyclical, that is to say, monitoring time will be limited to several circles.

This mode of operation is particularly suitable for molding equipment.

The suitable mode of production is that knitting needles are usually not released for a long time, and all needle hooks should be able to be sensed by light sensors.

Different types of optical detection heads are selected according to different needle number.

Different types of optical probes can be used in the same control unit simultaneously.

The main functions of the needle sensor are: stopping immediately when the needle is detected; the 4 digit display can quickly locate the location of the broken needle; the lateral bending of the needle can be detected; if the maximum limit is adjustable, it will stop immediately; the monitoring of one or more separate columns can be gradually reduced; the control unit is automatically matched with the knitting needle type; the control unit can automatically coordinate with different operation speed; the larger voltage range is 11~28V (DC / AC); the sensing range of the optical probe is at (15 + 1) mm; the knitting needle recognition range is at 15~5000 root /s; the largest needle cylinder number 50E; relay output, the maximum 60V can be converted.
