Abstract

PURPOSE:To obtain an effective split bridle roll at a low cost by providing an air chamber by inserting a gum cylinder into its shaft, disposing a brake lining material on the outer periphery of the gum cylinder and inserting plural number of rolls fitting urethane gum rings on its outer part. CONSTITUTION:Rolls are combined as a pair of upper and lower ones, a slit coil is put between the two rolls. Then, when compressed air is fed to the air chamber 2 from an air feeding port 8 through using rotary joint, etc., the gum cylinder 3 expands to press contact the brake lining material 4 to the inner side of the rings 6. After then, when a braking force is given to the roll 1 to stop its rotation, as the slit coil material is wound by a winding machine and pulled, held by the urethane ring part 7 inserted on the periphery of the rings 6 on the upper and lower rolls to generate the tensions. The tensions are given equally to each slit coil material, the whole slit coil material are wound with averaged equal tension.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a split tension prydle roll that applies tension to a slit coil in a slitter line.

<Prior art> The conventional method of applying braking force to the split rings of split tension pry roll rolls was to apply braking force to the split rings from the sides of the roll using air cylinders, which resulted in differences in the braking force of the split rolls as they moved toward the center of the roll. It was difficult to apply uniform tension to the slit coil. Furthermore, since bearings were inserted between the split rolls and the shaft, costs were also high.

<Problems to be Solved by the Invention> It is an object of the present invention to provide a split priddle roll that has a simple structure, is inexpensive to manufacture, generates the same braking force on each roll of the split rolls, and can apply uniform tension to the slit coil. It is something to do.

Means for Solving the Problems〉 The system is configured to apply frictional braking force by air pressure from the inside of the split ring fitted to the shaft, and apply the same braking force to the entire one split ring, and the conventional one inside the split ring. 〇<Example> A rubber cylinder 3 is fitted to a stepped roll l, an air chamber 3 is formed between the rubber cylinder 3 and the four parts of the roll surface, and the outer periphery of the rubber cylinder is A band-shaped lining material 4 is provided, and a fixing member 5 fixes the rubber cylinder 3 and restrains the lining material 4.

On the other hand, the ring member 6 fitted with the urethane rubber ring 7 is fitted onto the shaft 1 provided with the lining material 4. Furthermore, a compressed air supply port 8 is provided for supplying compressed air to the air chamber 2 from the outside. The above is the configuration of the present invention.

Function> The rolls of the present invention shown in FIG. 1 are combined as a pair of upper and lower rolls, and a slit coil is sandwiched between the two rolls.

Next, compressed air is supplied from the outside to the air chamber 2 through the air supply port 8 using a rotary joint or the like. When compressed air is introduced, the rubber tube 3 expands outward, and the lining material 4 is pressed against the inside of the ring 6.

After that, when a braking force is applied to roller 1 to stop its rotation,
When the slit coil material is wound and pulled by a winder, it is held by the urethane ring part 7 fitted to the outer periphery of the ring 6 of the upper and lower rolls, and tension is generated. The slit coil material with high tension is brake lining material 4.
Since the ring 6 is pulled by overcoming the frictional force of the inner diameter of the ring 6, the ring 6 having the urethane ring portion 7 rotates while rubbing 17 times between the ring 6 and the brake lining material 4. Even if there is a difference in the plate thickness of the slit coil and a difference in the winding diameter, this action applies tension equally to each slit coil material, and all the slit coil materials are wound with the same tension on average. This is because the pressure applied to the lining by air pressure from inside the rubber tube 3 is constant.
This is because the friction torque required to rotate each ring 6 is constant.

As described above, the divided priddle roll can apply uniform tension to each slit material.

<Effects of the Invention> Since the present invention can apply braking force evenly to the split rings fitted to the shaft from the inside of the shaft, it is possible to apply uniform tension to each slit coil, and each ring Since there is no need for a bearing inside the split prydle, it is possible to provide a split prydle that is inexpensive and highly effective.
