NEW JOB can work in the textile field on preparation, spinning, winding, weaving, finishing and bleaching both for natural fibers and synthetic fibers systems.
Besides the above mentioned activities, we would like to point out the following system which can offer and supply to the spinning mills:
We can oer and install an automatic doing system on the ring frames which are not equipped with this
device. The system can be applied on all types of machines (Lakshmi, Rieter, Zinser, Toyota, ecc.) with very
good result, reliability and optimum ratio quality/price.
It is controlled by a cam moved thanks to a motor reducer.
This solution allows to have more fluid movements and also to avoid swinging that can damage the system.
AUTO DOFFING CYCLE
Thanks to the double-peg plates you have a shorter auto-doffing cycle avoiding the parking position time.
SETTING POSITION FOR UP/DOWN AND IN/OUT OF THE DOFFING
Doffer up and doffer down:
contact-less linear position transducer.
Doffer in and doffer out:
Strong: Oilresistant and anti-ageing membranes.
Fast: membrane is studied to reduce opening and closing time.
Security:in case of deep impact grippers remove automatically.
EMPTY TUBES BOX
Empty tubes can be loaded in random way.
Mechanical system to set empty tubes. Mechanical and pneumatic system,very functionalavoids blocks.
The auto-doffing can be linked to winding machine.
The auto-diagnosis operating panel informs about eventualfaults and explain how to solve them.
Moreover there is an on-line link to NEW JOB diagnosis centre.
SAFETY AND CONTROL
Possibility to avoid the contemporary operation of two doffing devices if the distance between the ring-spinning frames is not enough for safe operation. Thanks to an emergency cord along the machine itis possible to stop the device at any point of operation position.Grippers are solid and easy to unhook (no screw needed).
How many minutes takes a cycle of doffing?
The doffing time can be adjusted by increasing the speed of up and downof the device. Minimum time is about 2 minutes, the recommended time is 3 minutes (more movement is slow and is more functional the system in time).
What is the speed of loading-unloading bobbin-tubes?
Even in this case, the plates being controlled by an electric motor the speed may be adjusted by varying the frequency of power to the motor and it can reach 1200 bobbin-tubes per hour.
We need to make some changes the ring spinning machine?
What types of safety devices are there?
What is the life of the membranes of the hand grip?
It depends on several factors such as the number of doffing made, compressed air quality, condition of the tubes. According to our experience of 1200 membranes with a number of doffing of 6 in 24 hours 5 membranes were changed in a year
