Claims

[Claims for Utility Model Registration] 1. A device provided on a reel having a spiral spring 2 on a drum 1, which includes a cutting detection section 3 for detecting damage to the spiral spring 2, and a brake 4 operated by the cutting detection section 3. A reel safety device comprising: 2. The cutting detection section 3 according to claim 1 includes a spiral spring 2, a pin 5 pulled in the opposite direction by a tension spring 21 having a weaker spring force, and the pin 5.
A reel safety device comprising a limit switch 6 that is engaged with the reel. 3. The cutting detection section 3 according to claim 1 is a detection pin 31.
This reel safety device is characterized in that one end of the detection pin 31 projects near the internal spiral spring 2, and the other end of the detection pin 31 contacts the limit switch 6. 4 The brake 4 according to claim 1 includes a brake pad 7 on the side of the reel and a biasing spring 8 for the brake pad.
A reel safety device comprising a lock pin 9 and a soletoid 10 for operating the lock pin 9. 5. The brake 4 according to claim 1 is the drum rotation shaft 1.
A safety device for the reel is an electromagnetic brake 12 provided coaxially with the reel.
