This feed roller uses a roller core material 2 as a base material, and the roller core material 2 is formed by surface-polishing a stainless steel round bar material. Roller core material 2
Rubber rings 3 made of synthetic rubber or the like are fitted at multiple positions on the outer periphery of the rubber ring 3 . That is, the rubber ring 3 is fitted into a groove 4 formed by & board processing on the surface of the roller core material 2, and the fitting is performed by inserting the rubber ring 3 from the - end side of the roller core material 2 in the direction of the arrow. This is done by inserting a rubber ring (there is also one in which a rubber ring is fitted directly onto the outer periphery of the roller core material without forming a groove). Further, when fitting, an adhesive is applied to the inside of the groove 3, and the rubber ring 3 is fixed to the groove 4 by the adhesive. The feed roller 1 thus formed serves as a contact portion between the outer circumferential surface of the rubber ring 3 and the paper to be fed, and the use of the rubber ring 3 was considered to be the best in terms of frictional contact performance with the paper. It has also been suggested that the roller core material 2 into which the rubber ring 3 is fitted and supported is preferably made of a stainless steel round bar or tube material. That is,
Stainless steel round bar materials are preferable because of the support performance and durability of the rubber ring, the ease of machining the groove 4 (it can be easily processed using a lathe, that is, the roundness of the groove 4 can be easily improved), etc. It was said that In addition, when fitting the rubber ring directly to the outer periphery of the roller core material without forming a groove, it is possible to use a stainless steel roller core material, or because it is easy to polish (process to achieve roundness). It was considered suitable.

。[Problems to be Solved by the Invention] However, in the conventional feed roller 1 described above, the rubber ring 3 is fitted to the roller core material 2 in order to maintain the feed performance of the roller surface. In the manufacturing process of 1, it is necessary to process and form the groove 4 on the roller core material 2 using a lathe, apply adhesive to the groove 4, and fit the rubber ring 3, etc., which increases the work cost. It was done. In addition, since the rubber ring 3 fitted to the outer circumference of the roller core material 2 is made of a material that deforms elastically, the roundness may vary depending on the state of support for the core material 2 (i.e., the state of fixation to the core material 2 with adhesive). The reality is that there is no such thing. Therefore, in practice, the surface of the rubber ring 3 is polished using a lathe or the like after the feed roller 1 is completed, so that the rubber ring 3 is rounded and the paper is fed smoothly.

い送り性能が保てる。The outer peripheral surface of the roller core material 11 is a roller surface 14, as shown in FIG. This roller surface 14 is formed by applying a film of urethane-based synthetic resin material to the outer peripheral surface of the roller core material 11 formed of a hard synthetic resin material and curing it, and is the contact surface with the copy paper being fed. CD & more specifically, it is referred to as the roller surface 14) on the surface of the convex strip 12. That is, the roller surface 14 is formed by spraying a urethane-based synthetic resin material onto the outer peripheral surface of the roller core material 11 using a spray gun 15. Spraying is performed by rotating the roller core material 11 in the direction of arrow A (see FIG. 3) and sliding it in the direction of arrow B (see FIG. 1) with respect to the blow-off nozzle of the spray gun 15. Spraying The film thickness of the urethane-based synthetic resin material is said to be at least 15 μm or more.Also, as the urethane-based synthetic resin material, polynisder urethane or pucryl urethane is used as a base material, and these base materials are coated with a curing agent or It is formed by adding additives such as ethylene fluoride.The weight ratio of the base material to the additive is considered to be approximately 10:1 to 4:1, and it is recommended to use thinner or the like as a solvent. It is considered appropriate.The sprayed urethane-based synthetic resin material is dried and cured under drying conditions of a drying temperature of 100°C to 150°C and a drying time of 10 to 30 minutes.In the examples, urethane-based synthetic resin material Ouflex 100 manufactured by Ohashi Chemical Industry Co., Ltd. was used as the resin material.The coefficient of static friction of the roller surface 14 thus formed was measured.The measurement was carried out using an AN-FQ friction tester manufactured by Toyo Pki Co., Ltd. As a result, it was found that the coefficient of friction was always 0.5 or higher, indicating that there was a frictional resistance against paper similar to that of a conventional feed roller equipped with a rubber ring. It was also found that the rubber ring has the same performance as rubber.Furthermore, unlike rubber rings, it does not deteriorate or distort, so better feeding performance can be maintained.

That is, the urethane-based synthetic resin material is applied to and integrated with the roller core material 11, which is also formed from a synthetic resin material, in a state that conforms to its structure. Since the urethane-based synthetic resin material has approximately the same 6-stroke resistance as rubber in its cured state, the roller surface has a smooth performance for feeding paper, etc.

１４等を容易に形成することができる。Further, according to the feed roller 10 according to the example 10, since the roller core material 11 is formed of a hard synthetic resin material such as ABS resin, it is possible to reduce the weight of the feed roller. In other words, compared to conventional feed rollers or roller cores made of stainless steel, the actual weight is 200g.
It is now possible to make the machine lighter, and if a copy machine uses 40 or more feed rollers, it can be made lighter by 8 kg or more by simple calculation. Moreover, the roller core material 11 made of a hard synthetic resin material has properties similar to stainless steel rods and tube materials in terms of durability and bending stress, and the roundness of the core material is also comparable to that of conventional stainless steel materials. The same is true. Furthermore, it is easy to mold, and the protrusions 12, engagement grooves 14, etc. can be easily formed by, for example, molding.

ものであってもよい。Furthermore, the applicant formed the roller core material from a round bar made of aluminum alloy, which is lightweight and strong, like the above-mentioned hard synthetic resin material, and also coated the surface of the roller core material with a urethane-based synthetic resin material. A feed roller was formed by spraying. As a result,
It has been found that it is possible to form a feed roller that is lightweight and durable like the feed roller 10 mentioned above, and in which the roller surface (urethane-based synthetic resin material) is in close contact with the core material. Therefore, the roller core H should be made of a material such as a hard synthetic resin material or an aluminum alloy that can maintain stress and roundness for durability 1 bending, and that can also be coated with a urethane-based synthetic resin material. It can be anything.
