Elscint Machine Combines Screw And Washer Assembly

Elscint Automation has developed an assembly machine for the assembly of screws with spring washers and plain washers. The machine consists of three vibratory bowl feeders: one feeding the screws, one the spring washers and one the plain washers. There is also a motorised rotary mechanism where the three parts (screw, spring washer and plain washer) are assembled.

A linear vibrator is used to convey the assembled parts forward. This machine can be used for feeding the assembled screw and washers to a threading machine. An assembly speed of up to 200 pieces per minute is possible with this machine, depending upon the screw size.

The machine has an additional provision to check and eliminate unassembled components. This ensures that only the correctly assembled components get fed to the threading machine. Sensors are used at four places to ensure smooth working of the assembly machine. This assembly machine works on single-phase supply. Various sizes of screws from M3 to M10 can be fed through a single machine with a slight changeover.

Connectors Available In Screw-Contact Versions

Souriau has announced that its standard UTS all-plastic connector range for severe operating environments is now available in a screw-contact version. The product allows easy connection with no need for dedicated tools and offers high-level sealing (IP68 and IP69K), as well as fast connections.

Connecting screw-termination contact UTS connectors does not require any specific expertise or tools; an ordinary screwdriver is enough to connect the wires to the contacts. This means that the connectors are especially suited to field applications including: tunnel ventilation; video-surveillance; traffic control and road signals; car park detection systems; and metrological measurement systems.

Screw-contact UTS connectors naturally benefit from the sealing performance offered by the UTS range, to IP68 or IP69K standards. This requires that characteristics remain stable when immersed to a depth of 10m and during high-pressure cleaning operations using 140 bar sprays. The sealing is retained even when the cable is pulled in all directions.

The material used - a high-performance plastic - is resistant to impact and vibration and offers good temperature performance (from -40C to 105C). In addition, the UTS connector is salt-mist resistant (for 500 hours) and UV resistant, increasing its reliability when used outdoors. Furthermore, UTS screw-contact connectors are intermateable and interchangeable with UTS layout crimp and solder contact versions.

In the same way, a connector with crimped or soldered contacts can be connected to a screw-contact terminal and vice versa. UTS screw-contact terminals are equipped with the Trim Trio locking mechanism: a one-third of a turn bayonet locking mechanism with a click-lock motion.

It is available in four- and seven-contact versions that are VDE 0110 certified (for low-power supplies and signal transmission without using the Ethernet protocol) and they mechanically rated at 250 mating cycles.
