Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a belt having a chitinous layer formed on its surface to impart antibacterial properties.

[Conventional technology]

BACKGROUND ART Conventionally, endless belts have been used for transporting foods, pharmaceuticals, etc. before packaging in manufacturing plants for foods, pharmaceuticals, etc. However, this belt is required to be non-toxic from the viewpoint of hygiene. In order to meet this demand, a belt whose surface is coated with a synthetic resin such as silicon or Teflon is currently used.

[Problems to be solved by the device]

However, the above-mentioned conventional belt is effective in terms of antibacterial property for preventing adhesion of bacteria and the like, but has little effect in terms of antifungal property for preventing mold adhesion. Therefore, it was not always satisfactory in terms of hygiene.

Then, this invention aims at providing a very hygienic belt having not only antibacterial properties but also antifungal properties.

Another object of the invention is to provide a belt of the above type which can be manufactured easily and inexpensively.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, the chitinous layer (3) is formed on at least the transport surface of the belt (1). The chitinous layer (3) may be directly formed on the surface of the belt core body (2), or may be formed on the surface of the elastomer layer (4) coated / formed on the surface of the belt core body (2). May be.

Further, the chitinous layer (3) may be provided only on the conveying surface of the belt (1), but may be formed on the entire surface of the periphery.

[Action]

Although chitin has antibacterial properties, it is particularly excellent in antifungal properties, so that foods, pharmaceuticals, etc. can be transported in a hygienic manner.

〔Example〕

The configuration of the present invention will be described below with reference to the drawings shown as examples.

FIG. 1 shows a first embodiment of the present invention. A belt (1) according to the present invention has a chitinous layer (3) only on the surface of a belt core (2) made of canvas or the like, that is, on the conveying surface. ) Is formed directly. The chitinous layer (3) is formed by adhering a sheet of chitinous material to the surface of the belt core body (2), or applying fluidized chitinous material to the surface of the belt core body (2) or heating. Then, it can be formed by a method such as fusion bonding. This embodiment is suitable for a conveyed product that does not need to impart elasticity to the surface of the belt core body (2).

FIG. 2 shows a second embodiment of the present invention, in which the chitinous layer (3) is formed on the surface of the elastomer layer (4) coated on the surface of the belt core (2). It is only different from the first embodiment. In some cases, the surface of the belt (1) needs to be elastic depending on the material to be conveyed, and in such a case, this embodiment is suitable.

The elastomer layer (4) can be formed from a known material such as synthetic resin such as polyurethane or synthetic rubber.

The chitinous layer (3) may be provided only on the conveyance surface side of the belt (1) that directly comes into contact with a conveyed product such as food.
In order to sufficiently secure the antibacterial property and antifungal property, it is preferable to provide the belt (1) on the back surface and the side surface so that the entire periphery of the belt (1) is covered with the chitinous layer (3).

[Effect of device]

The present invention has the above-mentioned structure, and therefore, at least the transport surface of the belt (1) has the chitinous layer (3) having excellent antibacterial and antifungal properties. Not only that, it has a mildew-proof property and can provide a very hygienic belt. This is particularly useful in foods and medicines that are required to be nontoxic in hygiene, and in manufacturing plants for semiconductor-related products where it is necessary to eliminate minute dust as much as possible.

Further, the present invention has an effect that it can be manufactured easily and inexpensively because the chitinous layer (3) only needs to be provided on the surface of the belt (1).

When the chitinous layer (3) is provided on the entire surface of the belt (1), the antibacterial property and the antifungal property are further improved.
