Winding machine for raffia spools

Winding machine for raffia spools, consisting of a bench (1), which supports a base plate on which the various sub-stations of the machine are located, a bench (1) fitted with a perimeter safety enclosure (2), a machine with a pair of conveyor belts (10-10′) on which the body and cap of the spool are respectively fed into the machine, and a conveyor belt (10″) on which finished spools are discharged;

• the area where they are discharged by the conveyor belts (10-10′) contains a 4-axis robot (3) with the means to handle both the two parts of the spool, and the spool unit onto which thread has previously been wound;
• the robot is fitted with a reel gripper (40 and has, on both sides, a winding station (5), a support centring system (6), a feed reel (9), a thread handler (7) and a thread guide (8), where:
• a) The winding stations (5) include the means to receive and rotate the body of the spool.
• b) The support centring system (6) includes the means to exert pressure on, and consequently attach, the cap to the body of the spool, and the means to manoeuvre horizontally over the operating area.
• c) The feed reels (9) supply the thread guide unit (8)
• d) The thread guide unit (8) includes the means to guide the thread towards the spool.
• e) The thread guide unit (8) supplies a thread handling unit (7) consisting of 3 pneumatic shafts and a further two pneumatic actuators, including the means to jam, cut and position the thread.
