The present invention relates to a roll stacking device for mounting a roll, such as a back-up roll for supporting the rotational drive of the rolling roll used in the rolling line of the steel mill in the workplace during repair or replacement of the roll, in particular, the backup The surface of the roll is worn out to prevent the collision between the roll and the loading equipment due to the rolling phenomena of the roll when loading the roll for reuse in the equipment after polishing, thereby preventing the surface damage of the roll and the damage of the loading equipment. In particular, the present invention relates to a roll stacking device in which roll breakage is prevented to facilitate the stacking operation.

In general, many rolling machines are installed in a rolling line which is essentially required in the manufacture of steel sheets in a steel mill, and such a rolling mill is composed of a work roll for rolling a material in contact with a rolled material and a backup roll for supporting the roll. Since the surface is easily worn, the surface of the backup roll should be polished through regular inspection.

By the way, since the backup rolls are usually installed in one rolling machine up and down, in order to facilitate the movement and polishing of the rolls and to quickly reassemble the rolling mill, one pair of backup rolls is loaded. In a two-stage stack, a conventional roll loading operation for two-stage stacking of such a backup roll is shown in FIGS. 1 and 2.

That is, as shown in Figures 1 and 2, the roll neck 102 portion is caught on the lower mounting plate 110 to load one backup roll 100 via the protective plate 120, and then After the other protective plate 120 'is interposed over the vertical stand 112 is to load another backup roll (100').

On the other hand, when the back-up rolls 100, 100 'are subjected to surface polishing, a considerable time is often required until they are put back into the line, so that the roll necks of the back-up rolls 100, 100' are rolled. Parts (102) and (102 ') should be oiled and packed to maintain precision, ie to prevent corrosion.

However, as shown in Figure 2, in the conventional loading operation of the roll using the mounting table consisting of the lower mounting plate 110 and the vertical stand 112, because the first simply put the roll in the vertical direction When the lower roll 100 and the upper roll 100 'are placed thereon, sliding of the roll occurs and the surface of the rolls 100 and 100' collides with the vertical stand 112 of the mounting table. This is likely to be damaged.

In addition, since the roll neck 102 is mounted on the lower plate 110, the roll neck 102 portion is seated on the lower plate 110, so that the oil coating and packing work of the roll neck 102 may be difficult. 100) and the roll 100 'seated on the upper side are inclined to exert a force on the vertical stand 112 on the opposite side, while the deformation of the loading table itself occurs easily, in particular, the work space of the roll 100 seated on the lower side. This narrow work is difficult for the operator, such as crane work for the movement of the roll, the load time of the roll, as well as a considerable amount of time required for its movement, there is a problem that workability is significantly reduced.

The present invention has been made in order to solve the various problems of the prior art, the object of which is that the back-up rolls are individually stacked without contacting each other at the bottom and the top, and at the same time the neck portion of the roll protrudes It is easy to apply and pack oil, and more stable loading of rolls on top and bottom so as to prevent damage of roll and loading device due to roll loading device collision without roll shaking or slipping in loading device. It is to provide a roll stacking device which prevents roll breakage.

In addition, another object of the present invention, as well as easy to load the upper and lower rolls, as well as the roll neck portion is maintained in the protruding state without contacting the loading device, oil coating and packaging operations for maintaining the accuracy of the roll neck An object of the present invention is to provide a roll stacking device in which roll breakage is easily performed.

As a technical configuration for achieving the above object, the present invention is equipped with a lower plate and vertical bars formed vertically integrally to both sides thereof, the mounting table is seated on the back up roll;
