Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a conveyor belt having a rising part or an inclined part.

[0002]

[Prior Art]

 As a conventional conveyor belt of this type, there is known a conveyor belt constructed as shown in FIGS. 3 and 4, for example.

Referring to the drawings below, reference numeral 1 denotes a horizontal portion 2 at the lower end, a portion 3 that rises vertically from one end of the horizontal portion 2, and a portion 4 that extends horizontally from the upper end of the rising portion 3. This is an endless conveyor belt. The conveyor belt 1 has corrugated ears 6 on both sides along the lengthwise direction on the surface of the endless base portion 5 and is located between the ears 6, 6 on both sides. Horizontal bases 5 are provided at appropriate intervals in the longitudinal direction of the base portion 5.

In such a conveyor belt 1, one end of a horizontal portion 4 at the upper end is hooked on a roller 8 driven by a drive motor (not shown), and the other end of the horizontal portion 2 at the lower end or a corner portion (a bent portion). ) Are respectively hung on the roller 9 or the pulley 9a to form a vertical belt conveyor device as shown in FIG.

With such a vertical belt conveyor device, for example, when a powdery or granular material to be conveyed is supplied to the lower end from one end side of the horizontal portion 2 and is conveyed, as shown in FIG. The object to be conveyed is lifted while moving in the direction of the arrow together with 5, but the weight of the object to be conveyed is in the direction of pushing it down with respect to the horizontal rod 7.

In particular, the joint portion of the horizontal joint 7 to the base portion 5 is integrally provided with a plate portion 10 projecting in front of and behind the horizontal joint 7, and at the base of the horizontal joint 7 and the plate portion 10, the object to be conveyed is provided. Therefore, there is a problem in that the load applied to the horizontal shaft 7 is concentrated and a crack is generated at the root portion 11 on the rear side in the moving direction of the conveyor belt 1.

Further, although the plate portion 10 is joined to the base portion 5 and the horizontal joint 7 is attached, recently, the diameter of the roller for hanging the conveyor belt 1 tends to be small, and the plate portion is provided at the roller portion. When the portion 10 is stretched in a curved shape, there is a problem that the portion is peeled from the base portion 5 due to fatigue.

[0008]

[Problems to be solved by the device]

 The present invention solves such a problem, and aims to disperse the load applied to the base portion of the horizontal shaft, eliminate the occurrence of cracks and peeling, and prolong the life of the conveyor belt. is there.

[0009]

[Means for Solving the Problems]

 In order to solve this problem, the present invention provides corrugated ear lugs on both sides along the length direction on the surface of the base portion, and is located between the ear lugs on both sides, and laterally spaced at appropriate intervals in the length direction of the base portion. A board is provided integrally with the horizontal board for attaching the horizontal board to the base portion, and a hollow portion is provided on the back surface of the board at the base of the horizontal board and the board.

[0010]

[Action]

 With this configuration, the load applied to the base of the horizontal shaft when receiving the object to be transported is distributed in the cavity, eliminating the problems of cracks at the base and peeling from the base, thus increasing the life of the conveyor belt. Can be promoted.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In the figure, the same reference numerals as those of the conventional example indicate the same members, and detailed description thereof will be omitted.

In the figure, a horizontal member 7 is a plate portion 10 that is bonded, thermocompression-bonded, or mechanically fixed to the surface of the base portion 5, and a central portion of the plate portion 10 in the front-rear direction (moving direction of the conveyor belt 1). Further, the inclined portion 12 inclined toward the moving side of the conveyor belt 1 at an angle of about 65 degrees with respect to the rising plate portion 10 and the tip (upper end) of the inclined portion 12 continuously provided at an angle of about 10 degrees with respect to the plate portion 10. The conveyor belt 1 includes a tip inclined portion 13 inclined toward the moving side. The cross member 7 having such a structure has elasticity by being made of a strongly vulcanized synthetic rubber or natural rubber, and further has a plate portion at the base of the inclined portion 12 and the plate portion 10. A triangular cavity portion 14 is formed on the back surface of the central portion of the front-rear direction 10 over the entire length of the horizontal shaft 7 in the horizontal direction. The other structure is the same as that of the conventional example.

In the above-mentioned structure, the side wall 7 is provided with the triangular hollow portion 14 on the back surface of the plate portion 10 at the base of the inclined portion 12 and the plate portion 10. Even if the weight of the conveyed object is applied to the root portion, it is dispersed in the cavity portion 14, increasing the elasticity of the root portion, and the fatigue of the lateral joint 7 causes the rear root portion in the moving direction of the conveyor belt 1 to move. It is possible to prevent the occurrence of cracks in 11 and further prevent the plate portion 10 from peeling off from the base portion 5, thereby extending the life of the conveyor belt 1. The same effect can be obtained if the shape of the hollow portion 14 is other than a triangular shape.

Further, since the slanted portions 12 and 13 receive the transported object, it is possible to transport a large amount of the transported object as compared with a conveyor belt having no slanted portion 13 at the tip thereof, and the horizontal swinging direction There is no spilling of the transported object from 7. Although the angle of the inclined portion 12 is about 65 degrees and the angle of the inclined portion 13 is about 10 degrees in the above embodiment, the angle is not limited to this angle.

[0015]

[Effect of the device]

 As described above, according to the present invention, by receiving an object to be transported, the load applied to the base portion of the horizontal joint is dispersed, eliminating the problems of cracking at the base portion and separation from the base portion, and The life can be extended.
