Description

(54) USER FOR INSTALLING A ROLLER ON THE AXIS DRIVER'S AXIS ROLLER

I

The invention relates to the processing of metals by pressure and, in particular, can be used in workshops for the processing of rolled sheet rolled into a roll.

A device is known for removing and placing a roll on an axis of a winder consisting of a drive of the winder and a cantilever trolley feeding rolls of steel tape 1 which are perpendicular to one another.

However, this device can not provide automatic installation on the axis of the drum uncoiler rolls of different diameters.

It is also known a device for mounting a roll along the axis of a drum of a decoiler, comprising a walking conveyor with successive roll slots, a trolley with a slot for receiving a roll, and a photo relay 2.

A disadvantage of the known device is that the signal for automatic locking of the roll along the axis of the drum of the decoiler is taken over the outer diameter of the roll, which cannot provide sufficient accuracy. In addition, automatic centering of the drum axles of the unwinder and the inner diameter of the roll

is provided due to the considerable complexity of the device due to the introduction of several gear and rack gears into its design, which leads to a decrease in the reliability of its operation.

The aim of the invention is to improve the reliability of the device.

This goal is achieved in that a device for placing a roll on a; -and a drum unwinder containing a walking conveyor with slots for a Q-roll, a trolley with a slot for receiving a roll, a control system with a photo relay, is equipped with a second photo relay installed along the last slot of the walking conveyor , and a ruler mounted on a trolley, with the first photo relay mounted on

15, and both photo relays are mounted with the possibility of synchronous movement in the direction perpendicular to the axis of the drum of the uncoiler.

FIG. 1 shows the device, a general view; in fig. 2 - the same plan.

The device includes a walking conveyor with nests for rolls, including a movable frame 1 and a fixed frame 2, a carriage 3 with a hydraulic cylinder 4, on the plunger of which a nest 5 is mounted. On the axis of the last nest of the fixed frame 2 there is a hydraulic cylinder 6, on the rod of which a photo relay 7 is mounted. The trolley 3 is fitted with a hydraulic cylinder 8 connected by a pipeline 9 with a hydraulic cylinder 6. A photo-relay 10 is mounted on the rod of the hydraulic cylinder 8. A ruler 11 is mounted on the slot 5 of the trolley 3. In addition, in FIG. 1 shows a drum 12 uncoiler 13, rolls 14-16 and a spool 17.

The device works as follows.

At the next step of the movable frame 1, the roll 16 is installed in the extreme seat of the fixed frame 2. After that, the working fluid is supplied under the piston of the hydraulic cylinder 6, which goes in the lowest position, to the level of the lower part of the inner cavity of the roll 16 When the piston moves, the working fluid from the upper part of the hydraulic cylinder 6 through the pipeline 9 passes into the hydraulic cylinder 8, which causes its shaft to move downwards from the photo relay 10. When the photo relay 7 is at the bottom level The internal cavity of the roll 16 generates a signal to turn off the spool 17 of the working fluid supply to the hydraulic cylinder 6. At the next step of the moving frame 1, the roll 16 is installed in the slot 5 of the trolley 3, and the roll 15 in the extreme slot of the fixed frame 2. The movable frame 1 returns to its original position . Then, a pump (not shown) is turned on, supplying the working fluid under the lowest position of the plunger of the cylinder 4, on which the nest 5 is mounted. Moving the nest 5 occurs until the photo relay 10 crosses the beam 11. This gives a signal to stop the pump the working fluid in the hydraulic cylinder 4, and the nest 5 of the carriage 3 takes a certain position in height, at which the axis of the roll 16 coincides with the axis of the drum 12. The trolley 3 together with the roll 16 moves to the decoiler 13, and the roll 16 is put on the drum 12. Thereafter, the hydraulic cylinder 4 with the socket 5 and the hydraulic cylinders 6 and 8, together with the photo relay 7 and 10, as well as the carriage 3, return to their original position.

The advantage of the present invention is the accuracy of the installation of the rolls along the axis of the drum of the unwinder and the simplicity of the device design, which allows

to create both a reliable and easy-to-operate device.
