Abstract

PURPOSE: To provide a suction roll that can be manufactured at low cost and is excellent in suction force by providing a number of slits on the outer peripheral surface of the roll that are extended in the direction of the roll width and parallel to a shaft rod, and conveying a long sheet-shaped subject to be conveyed, while sucking air from the slits. CONSTITUTION: This suction roll is provided with a number of slits 3 extended in the direction of the roll width, being parallel to a shaft rod, and provided on its outer peripheral surface in contact with a long sheet-shaped subject to be conveyed, and conveys the long sheet-shaped subject to be conveyed, while sucking air from the slits 3. Since the numerous slits 3 are provided in the direction of the roll width, the opening rate of the overall peripheral surface of the cylinder is large, the suction force increases, and even if this suction device is small in diameter and low in ability the long sheet-shaped subject to be conveyed is subjected to sufficient suction so that it can be conveyed with safety. Further, not a number of suction holes are bored but the numerous slits 3 are formed in the outer peripheral surface by molding in the direction of the roll width, with the result that the suction roll can be manufactured at low cost.

2. Description of the Related Art When a conventional thin film, cloth, or long sheet-like conveyed product is conveyed, the long sheet-like conveyed product is supported and conveyed on a conveying roll while maintaining a predetermined tension. As the conveying rolls, two conveying rolls are sandwiched between a pair of nip rolls to guide the conveyance, and one conveying roll is simply guided while adsorbing the long sheet-like conveyed product onto the surface of one driving roll, for example, a suction roll. Are known and are used in transport devices. However, since the suction roll has a difficult manufacturing process and is expensive, a pair of inconvenient nip rolls having a large number of parts are used.
As an example of such a suction roll, the applicant has previously arranged a large number of small circular air intake holes on the surface of a cylinder that contacts one side of the transported object, as described in Japanese Patent Application Laid-Open No. 5-24726. We proposed a suction roll in which a wire rod was wound around the surface of the cylinder with an appropriate gap.

However, in the suction roll having a large number of small circular holes, the long sheet-like conveyed product is strongly adsorbed on the roll surface, and the long sheet-like conveyed product and the conveying roll are combined with each other. In order to generate as much friction as possible, it is necessary to perforate and arrange many holes on the surface of the transport roll, which results in much cost and cost for the perforation step. Further, when the suction force from the suction holes on the surface is increased in order to increase the friction between the both, traces of the suction holes are generated in the long sheet-like conveyed product, which lowers the commercial value. Further, as a method of increasing the frictional force, it is also possible to coat the surface of the cylinder with a breathable rubber or an elastic porous material, but the porous material is heavily fatigued and the replacement cost is high and the cost is high. In addition, there was no great effect on the prevention of the traces of suction. In addition, it is known that the surface of a cylinder having an air intake hole is coated with a special metal mesh made by electroplating or a synthetic resin net such as nylon, but it may cause clogging in a short time. There was a problem in the repair and replacement of this cylinder due to the surface failure of the wire mesh and the life was short. The cylindrical outer cylinder formed by combining porous sintered metal had a weak adsorption force due to the existence of innumerable holes, was not suitable for high-speed transportation, and was quickly clogged. . Moreover, cleaning and regeneration were difficult.

Since the suction roll of the present invention is provided with a large number of slits extending in the width direction of the roll on the outer peripheral surface, the open area ratio of the entire peripheral surface of the cylinder is large and the suction force is large.
Even if the diameter is small, even if the capacity of the suction device is low, a sufficient suction action can be applied to the long sheet-shaped conveyed material to stably convey it. Furthermore, since it is possible to manufacture by forming a large number of slits by extending in the roll width direction on the outer peripheral surface by molding without forming a large number of intake holes on the outer peripheral surface with a perforation drill or the like, it is possible to manufacture at low cost. be able to. Further, a cylindrical body is fixed to a rotary shaft connected to a drive source, and a large number of radial ventilation chambers are arranged in parallel from the inner cylinder of the cylindrical body toward the outside at regular intervals and the tip of the ventilation chamber is opened. Since a large number of parallel slits extending in the axial direction of this cylindrical body are arranged in parallel, the intake chamber or the exhaust hole of the shutter member is operated by the intake action from the exhaust port connected to the pipe communicating with the blower. By communicating with the exhaust hole of the fixed shutter member, the ventilation chamber of the rotating cylindrical body, and the slit, the long sheet-like conveyed product is conveyed while being adsorbed on the surface of the cylindrical body. Therefore,
The suction force is strong because it is sucked from the narrow slits in which a large number of cylinders that rotate at high speed are arranged, and the opening ratio is larger than that in which a large number of air holes are arranged, so the suction area is increased. It can beat the intake power. Therefore, even with a narrow slit, effective transport can be performed,
Even if the suction device has a small output, it is possible to reliably convey the long sheet-shaped conveyed material while adsorbing it.

Further, this suction roll can be easily manufactured by integrally molding a cylindrical body having radial ventilation chambers and slits at regular intervals. Since the columnar plate extending in the axial direction is formed because the radial ventilation chambers are arranged, the amount of roll deflection can be reduced even if the columnar plate is formed of a lightweight alloy such as aluminum. Further, according to the suction roll of the present invention, it is possible to prevent the generation of slit traces on a long sheet-like conveyed product by winding a filamentous material such as stainless steel, for example, a wire around the surface of a cylindrical body having a slit. it can. In addition, for example, by fitting a mesh made of rubber, nylon, urethane or the like or a pipe made of a metal mesh on the surface of this cylindrical body, a long sheet-like conveyed product conveyed to the surface is adsorbed extremely softly. In addition, it is possible to efficiently convey the long sheet-shaped conveyed product without leaving a trace of suction on the long sheet-shaped conveyed product by using a small suction device as compared with the conventional suction roll.

As described above, since the radial ventilation chambers and the elongated slits can be integrally formed in the cylindrical body 2, a rotatable outer cylinder provided with a large number of perforations and an inner cylinder provided with the ventilation holes are formed. It can be easily manufactured as compared with a conventional suction roll having a double structure. The suction roll of the present invention can generally be manufactured to have a diameter of 90 to 500 mm and a length of 100 mm to 6 m. In particular, aluminum is lightweight, but it is structurally difficult to bend because a large number of radial column plates are arranged, and the amount of bending is about 1 compared to the conventional suction roll with many small circular holes. /
Third place. Further, since it is lightweight, it has a small moment of inertia, so that the responsiveness when the rotation is stopped or rotated is fast.

Since the suction roll of the present invention is constructed as described above, it has the following effects. 1) It was necessary to punch a large number of holes in order to improve the conventional frictional force, but since punching work is not required and a roller with a slit structure can be easily manufactured by extraction molding, the cost is low and the manufacturing cost is low. You can do it. 2) The opening rate of the roll surface is large, and the opening rate is about 3 times that of conventional punched products. Therefore, suction efficiency is good, so suction rolls with a small diameter can be used, and the manufacturing cost is low. Since it is possible to reduce the moment of inertia, the response to acceleration and deceleration is fast. 3) Since the fixed inner cylinder unlike the conventional product is not required, the contact accident of the inner and outer cylinders due to the deformation due to the temperature difference between the outer cylinder and the inner cylinder or the deformation due to the bending of the roll does not occur. 4) Since the intake efficiency is high, sufficient results can be achieved with a small intake device.
