ヤベルト３が公知である。 2. Description of the Related Art Conventionally, conveyor belt devices for conveying steel plate materials for processing, etc. have been desired to be small in size due to rationalization of installation space. For this reason, it is necessary to reduce the diameter of the pulley, and as a belt that is inexpensive, has high flexibility that easily adapts to the pulley, and has shock absorbing properties, a tensile strength core layer 1 is used as shown in Fig. 1. A resin conveyor belt 3 is known, which has a cover layer 2 made of a soft thermoplastic resin on the upper surface thereof.

い。 However, since the conventional belt uses a soft thermoplastic resin for the cover layer 2 as a belt with high flexibility and shock-absorbing properties, the cover layer 2 has high abrasion resistance and is susceptible to collisions with the edges of conveyed items. It has the drawback of poor crack resistance and extremely shortened belt life. For this reason, there are restrictions on the hardness and thickness of the cover layer 2, and no solution has been found yet.
本考案はかかる事情に鑑み考案されたもので、
衝撃緩和性を有する撓み性の大きいベルトであつ

るという構成にした。 This invention was devised in view of such circumstances,
The purpose is to obtain a conveyor belt that is highly flexible and has shock-absorbing properties, and has excellent abrasion resistance and crack resistance. , on the surface of at least the upper cover layer made of soft vinyl chloride resin, convex portions having a generally rectangular cross section in the longitudinal direction that are continuous over the entire width in the belt width direction and at intervals in the longitudinal direction of the belt are provided, and at least the convex portions are It has a structure in which a covering layer made of hard urethane resin is provided including the top surface.
以下、本考案を第２図乃至第３図の一実施例に
基づいて説明する。 Hereinafter, the present invention will be explained based on an embodiment shown in FIGS. 2 and 3.

ベヤベルト１６である。 Canvas is generally used as the tensile strength core layer 11 of the conveyor belt, and a cover layer 12 is disposed on the upper surface of the tensile strength core layer 11, and a cover layer 12 is provided over the entire width of the belt and in continuous lengths at intervals in the longitudinal direction of the belt. A conveyor belt 16 made of resin is provided with a convex portion 13 having a substantially rectangular cross-section in the direction, and a coating layer 15 made of hard urethane resin that covers at least the top surface 14 of the convex portion 13.

レタン樹脂にて製した被覆層を設けても差支えな
い。又被覆層１５に用いられる硬質ウレタン樹脂
の硬度はJIS−Ａ硬さ80〜95゜が用いられる。 The hardness of the soft vinyl chloride resin used for the cover layer 12 is determined depending on the application, taking into account the thickness of the cover layer, and JIS-A hardness of 40 to 60 degrees is used. Furthermore, in this embodiment, the cover layer 12 is disposed only on the upper surface of the tensile core layer 11, but in consideration of the shock absorbing property when a foreign object gets caught between the pulley and the belt, covers are placed on both the upper and lower surfaces of the tensile core layer. Arrange the layers,
In addition to providing the aforementioned convex portions on the surface of each cover layer, a covering layer made of hard urethane resin may be provided covering at least the top surface of the convex portions. The hardness of the hard urethane resin used for the coating layer 15 is JIS-A hardness of 80 to 95 degrees.
尚、他の実施例として、被覆層が凸部の全てで
あつてもよく、さらに凸部を含みベルト表面全域
に渡つて、一様に薄肉（0.2〜0.5mm）な硬質ウレ
タン樹脂を被着しても差支えない。 In addition, as another embodiment, the coating layer may cover all of the convex portions, and furthermore, a thin (0.2 to 0.5 mm) hard urethane resin may be uniformly coated over the entire belt surface including the convex portions. I don't mind if you do that.
凸部について説明を加えると、凸部の幅方向に
適宜数に分割する切欠きを長手方向に設けること
が望ましく、又凸部を設ける長手方向間隔は搬送
品の大きさ等により適宜決められる。 To explain the convex portion, it is desirable to provide a notch in the longitudinal direction that divides the convex portion into an appropriate number in the width direction, and the interval in the longitudinal direction at which the convex portion is provided is determined as appropriate depending on the size of the conveyed item, etc.
次に本考案の樹脂製コンベヤベルト１６の作用

を有する。 Next, the effects of the resin conveyor belt 16 of the present invention will be explained. Resin conveyor belt 1
6 has the above-mentioned structure, and since the cover layer 12 is made of soft vinyl chloride resin, it is soft and has shock absorbing properties, as well as flexibility that allows it to easily fit into the pulley.

又凸部１３は幅方向全幅に設けてあるため、ベル
トの長手方向の屈曲性がよく、プーリーになじみ
易い撓み性を助長する効果がある。 On the other hand, a hard urethane resin coating layer 15 formed on the surface of the cover layer 12 and including at least the top surface 14 of the convex portion has excellent wear resistance and crack resistance, and protects the cover layer 12 from conveyed goods. effective.
Further, since the convex portion 13 is provided over the entire width in the width direction, the belt has good flexibility in the longitudinal direction, and has the effect of promoting flexibility to easily fit into the pulley.
硬質ウレタン樹脂は撓み性を損う性質の材料で
あるが、被覆層１２が凸部１３に存するものであ
れば、樹脂製コンベヤベルト１６の撓み性に影響
を与えることはない。 Although the hard urethane resin is a material that impairs flexibility, as long as the coating layer 12 is present on the convex portions 13, it will not affect the flexibility of the resin conveyor belt 16.
尚、被覆層が凸部を含みベルト表面全域に渡つ

ベヤベルトの撓み性を損うことはない。 Note that even if the coating layer is uniformly applied over the entire belt surface including the convex portions, the coating layer may be thin (0.2 ~0.5mm), it will not impair the flexibility of the conveyor belt.
尚、カバー層１２に用いられる軟質塩化ビニル
樹脂は安価な樹脂であり、コスト面でも利点を有
する。 Note that the soft vinyl chloride resin used for the cover layer 12 is an inexpensive resin and has an advantage in terms of cost.
