Description

The invention relates to mechanical engineering, in particular, to the construction of devices for unwinding and transporting rolls of lengthy material.

The purpose of the invention is to increase productivity by automating the process of transporting rolls and improving reliability.

FIG. shows the proposed device, a general view; figure 2 - section aa in fig „1; in FIG. 3, node I in FIG. 2; FIG. 4 is a section BB in FIG. figure 5 is a view In fig.b

The device comprises a frame 1, a ram, a drive rod 2 that is not pulling in the frame, a roll axial locking mechanism mounted on the rod 2, a drive trolley 3, a vertical C-shaped rack 45 mounted on the trolley 3, a roll centering mechanism mounted on the rack 4, and also a drive for placing rolls.

The drive is manufactured in the form of a bed 5 mounted on the bed 5 of an inclined discharge trough-shaped tray 6 with an inclination in the direction of the mentioned mechanisms, the bunker 7 and the unit for issuing rolls to the tray b, filled in the form of a power cylinder 8 and connected to its movable element 9 and pusher 10 The mechanism for centering the rolls is implemented in the form of 4 vertical guides mounted on a rack mounted in a rack 4 parallel to the last f of screw 12, articulated with the latter and placed in the guides 11 of the upper 13 and lower 4 prisms, fixed The coil position monitoring sensor 15 on the prism 13, as well as the shock absorber 16 mounted on the A-pillar. The axial locking mechanism of the roll is made in the form of a rotor mounted in the frame I sJuiaH-17 with fingers 18 of the cams 19 mounted on the rod 2 of the conical sleeve 20 connected to 4) lanzm 17 and cams 19 of elastic elements 21. pins 22 with 23 covering them, and also connected to pins 22 of anvil 24. In f1: the butt 17 holes 25 are made to accommodate pins 225 and the springs 23 are mounted between flange 17 and / pore 24.

Bearings 26 and 27 are mounted in the frame, in which 1X is located Flyian 7.

The trolley is mounted for movement along the guides 28 from the power cylinder 29. On the screw 12, nuts 30 are mounted, connected 5 with prisms 13 and 14, the screw 12 is driven from the electric motor 31 via a gear 32. The rod 2 is connected to the movable element 33 of the power cylinder 34, Cams 19 10 are provided with a protrusion 35 for providing axial fixation of the rolls 36,

The device works as follows.

The rolls 36 are loaded into the hopper 7, iS. In the initial state, tech 3 is located in the left position (FIG. 4) 5 of the prism 3 and 14 is dispersed, the cone sleeve 20 is pushed to its extreme front position. In this case, the cams 20 19 under the action of the elastic elements 21 are reduced to the center of the rod 2. The stop 24 is in the extreme left position (FIG. 3) under the action of the springs 23,

By turning on the power cylinder 8, the pusher 0 is set in motion, which moves the rolls by one step equal to the width of the roll, while the outermost roll hits the path 6 and rolls down, setting 30 on the bottom prism 14. / and the dimmer 16 extinguishes kinetic energy roll roll down tray 6.

After that, the electric motor 31s is turned on, which, through the reducer 35, causes the screw 12 to rotate, the latter using nuts 30 moves the prisms 13 and 4 to the center, aligning the axis of the roll with the rod 2. At the same time, the sensor 15 gives the command to activate 40 the power cylinder 29 which moves the carriage 3 to the extreme right position, while the roll with its internal opening is placed on the collapsed cams 19, and the stop 24, with which help the roll is aligned in a plane perpendicular to the axis of the rod 2, moves to the rightmost position and, overcoming the force 23. In this position, the jQ roll 36 is set to the unwinding position.

25

After that, the command is given to turn on the power cylinder 34, which, by means of its movable element 33, moves the rod 2 with the taper bushing 20 to the right, the spreading cams 19 in contact with the taper bushing 20, release the Gmutg. and

fixing the roll along the axis of the rod 2.

Turning the electric motor 3 1 on the reverse by means of nuts 30 and screw 12, prisms 13 and 1A return to their original position: the latter release the roll, leaving it on the cams 9. Sensor 15, releasing the roll, gives the command to turn on the power cylinder 29, which returns the cart 3 to its original position, while the roll is prepared for unwinding.

After complete unwinding of the roll, by turning on the cylinder 34, the taper sleeve 20 is moved to

the extreme left position, with this, the cams 19 under the influence of the elastic elements 21 are compressed, and the stop 24 under the influence of the springs 23 moves to the extreme left position.

The further operation of the device in the automatic mode is carried out in the described sequence.

The technical and economic effect of the implementation of the invention is provided by increasing the productivity by automating the process of transporting the rolls and increasing the reliability as compared with the basic object.
