Ural Heavy Engineering Plant (54) DEVICE FOR TRANSPORTING ROLLS FROM STOP ONE ONE

A device for transporting rolls from a stack one by one relates to the field of metal forming and, in particular, can be used in tape processing workshops.

The known device, in which a hundred and ^five narrow rolls after winding the strip onto the reel drum, is transferred to one of the levers of the rotary device using a mobile lifting table and the coiler of the winder itself, where the rolls are manually tied and then removed by a crane from the lever for transfer to packing department 11]. The disadvantages of this device is the need for tying the rolls manually on the lever of the rotary device and the presence of crane operations when transferring the rolls for further processing.

It is also known an apparatus for trans-portation _m rolls comprising a rotator, a movable cart and tilting device having retractable tooth and tooth movement mechanism [2].

In this device, to prevent external turns of the roll, they must first be fixed, which significantly increases the processing time of the rolls and the consumption of strapping material, or left without fixing, but then it is possible to untangle and damage the external turns during transportation of the rolls. In addition, the transfer of the stack of rolls by a mobile trolley from the rotary device to the stationary tilter significantly complicates maintenance and reduces labor productivity. .

The purpose of the invention is to simplify maintenance and increase productivity. This is achieved by the fact that the device is equipped with mechanisms for tightening the outer turns of the roll, the first of which is mounted on a rotary device, the second on a tilter, while the tilter is mounted on a drive trolley. The mechanism for tightening the external turns of the roll mounted on the rotary device is made in the form of a rotary lever, a pressure roller mounted on one end of the rotary lever, and a hydraulic cylinder kinematically connected to the second end of the lever. The mechanism for preloading the external windings of the roll mounted on the tilter is made in the form of a system of levers, two rollers mounted on one of the levers of this system, and j cam associated with the tooth movement drive and pivotally connected to the lever system.

In FIG. 1 shows a device for transporting rolls from a stack j one at a time, a common view in FIG. 2 is a view A in Fig. ' 1; in FIG. 3 - section BB in FIG. 1; in FIG. 4 is a section BB of FIG. 3.

A device for transporting rolls from the stack one at a time comprises a turning device 1 and a mobile trolley 2 with a tilter 3.

In the housing 4 of the rotary device, the pinion shaft 5 with the head 6 and the lever 7 having a longitudinal groove ₂ and two hydraulic cylinders 8 with a rack 9 are mounted vertically for driving the rotation of the head, on which the lever 10 with the pressure roller 11 fixed to it is mounted and a 12 _ί hydraulic cylinder for swinging the latter. A mobile trolley 2 with a tilter 5 on it has a displacement drive from the hydraulic cylinder 13. The tilter includes a tilting lever and a hydraulic cylinder for turning this lever. In the slot of the canting lever 14 there is a tooth 16, the ejection of which varies depending on the width of the rolls in the foot by rotating the helm 17 of the screw pair _ζ 18. The lowering of the tooth 16 is carried out under the influence of gravity, and the lifting is done by the hydraulic cylinder 19 through the cam 2 0, articulated with two pressure rollers 21 by a system of levers 22 and _ζ ; a spring 23.

The device operates as follows.

In the initial position of the rotary device 1, which is necessary for receiving> the stack of rolls is worn on the lever 7, the ends of the outer coils must be located below and with their own weight of the rolls pressed against the supporting surface of the mobile lifting table, after which j the pressure roller 11 lifts the free ends to the rolls from below external turns, thus holding them from fluffing. Only after this, the movable lifting table is removed, and the stack of rolls is rotated by the hydraulic cylinders 6 of the rotary device until the longitudinal axis of the lever 7 coincides with the longitudinal axis of the mobile trolley 2 In the initial position of the tilter, the tilting lever 14 is maximally retracted from the rotary device and below the horizontal position, tooth 16 is lowered. The overturning lever 14 is installed by the hydraulic cylinder 15 in a vertical position, then the mobile trolley 2 with the hydraulic cylinder 13 is moved to the rotary device until the overturning lever comes into contact with the end of the roll and stops. The hydraulic cylinder 19 rotates the cam 20, simultaneously raising the tooth 16 and the pinch rollers 21. The tooth, pre-set to the width of the roll, removes the roll that is the last in the foot from the lever 7 and the pinch roller 11 of the rotary device, and the pinch rollers 21 abut against its outer diameter, holding the most external turns from fluffing. A mobile trolley with a roll returns to its original position, where the roll is tilted by 90 ^ and laid on the supporting surface of the lifting-turning device, in which the built-in rollers compress the outer turn, holding it from fluffing. Only after this, by turning the cam 2 0, the pressure rollers 21 are retracted from the roll, and the tooth is released and occupies a free position. The overturning lever falls below a horizontal position, the tooth leaves the roll zone. This completes the cycle of the device for transporting rolls from the stack one at a time. The roll is transferred by a lifting-and-turning device for further processing, where the strapping is done through the inner diameter with the simultaneous fastening of the external and internal coils. In such a device, the pressure rollers on the rotary device and the tilter can reduce the processing time of the rolls by eliminating the preliminary fastening of the outer turns before transportation, reduce the consumption of strapping material and eliminate damage to the outer turns, e <. Or they are not pre-fixed. The installation of the tilter on a mobile trolley allows you to exclude the cradle and the hydro-cylinder, the cradle lifting cylinder, which obscures the design and control circuit of the device. The mechanism for regulating the magnitude of the tooth outreach makes it possible to separate rolls of various widths from the foot.

Claims (2)

A device for transporting coils from the stack, one by one, relates to the field of metal forming and, in particular, can be used in tape processing shops. A known device, in which one hundred pa narrow coils after winding a strip on a winder drum, with the help of a movable lifting table and a pusher itself, is transferred to one of the levers of the rotator, where the hand rods are tied and then are removed from the lever to transfer in the packing compartment llj.
