专利摘要:
The invention can be used to automatically signal the end of material softening. The purpose of the invention is to increase reliability. To do this, in the central part of the reel 6 there is a grass-creating element in the form of an annular permanent magnet 3, and at the free end of the lever 9, a hinge fixed on the base 1, there is a magnetic control contact 2 with a possibility of interacting with the central part of the lateral surface of the roll 5. When unwinding the material, the diameter of the roll 5 decreases., The distance between the magnet 3 and the magnetically controlled contact 2 decreases, and at a given distance between them the contact 2 triggers, which turns on the alarm unit 7 . 1 il.

The invention relates to the production, and processing of roll materials, and can be used to automatically signal the end of unwinding of material rolled up.
The purpose of the invention is to increase reliability by eliminating the false triggering of the device during radial movements of the material placed on the roll axis.
The drawing shows a diagram of the proposed device.
A device for signaling the end of unwinding of a material roll placed on a reel comprises a base 1, a magnetically controlled contact 2, a floor-making element in the form of a permanent magnet 3, an axis 4 designed to place a roll 5 of material wound on the reel 6 on it, and block 7 signaling, as well as a support 8 fixed on the base, with which the axis 4 is rigidly connected, and a lever 9 hinged on the base 1, a magnetically controlled contact; the contact 2 is fixed on its free end of the lever 9 with the possibility of interaction with the central h Stu side surface of the roll 5 and the sub key to signaliza1dii unit 7, and a permanent magnet 3 vsholnen kol- forearm and intended cl securing the bobbin 6 in its central part.
The device works as follows.
During operation, the material roll 5 is unwound, the material is gradually consumed, and the diameter of the roll 5 decreases, the Magnet-controlled contact 2 attached to the free end of the lever 9 rests on the lateral surface of the roll 5 under the influence of gravity and

material consumption approaches the center of the coil and, consequently, the permanent magnet 3 fixed on the reel 6 in its center: the neutral part. The magnetically controlled contact 2 and the permanent magnet 3 begin to interact at a predetermined distance between them. As soon as the intensity of the magnetic field is sufficient to trigger contact 2, the alarm unit 7 is activated.
When the device is in operation, at the time the alarm unit 7 is triggered, the movements in the radial direction will not affect, since the floor-making element is fixed on the reel 6, which makes the indicated movements together with the roll 5.
Formula inventions
A device for signaling the end of unwinding of a material roll placed on a reel, comprising a base, a magnetically controlled contact, a floor-making element in the form of a permanent magnet, an axis designed for placing the reel on it, and an alarm unit, characterized in that, in order to increase reliability , it is equipped with a support fixed on the base, with which the axle is rigidly connected, and a lever hinged on the base; a magnetically controlled contact is fixed on the free end of the lever with the possibility of interaction with the central part of the side surface of the roll and connected to the alarm unit, and the permanent magnet is annular and intended to be fixed to the reel in its central part.
