Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt shape of a belt conveyor for mounting and conveying components on a mounting surface of a belt inclined in a direction perpendicular to a conveying direction, and particularly to a belt in a stable state. The present invention relates to a belt conveyor adapted to run on a belt.

[0002]

2. Description of the Related Art Hitherto, there have been proposed a number of regulating means for preventing a belt of a belt conveyor from meandering in a conveying direction.

For example, a linear protrusion is formed at the center of the bottom surface of the belt over the entire length in the direction in which the belt extends, and the peripheral surface of the protrusion is guided by a concave groove formed at the center of a plurality of transport rollers. Configurations are known.

[0004]

However, the above-described conventional means for preventing meandering is based on the fact that the belt support plate of the belt conveyor is formed horizontally, or the belt support plate is installed obliquely in the conveying direction. It is configured to regulate meandering when traveling on the top, for example, when the belt travels on a belt support plate that is inclined in a direction perpendicular to the transport direction, the belt is formed on the back surface of the belt By merely guiding the protrusion, a load acts on the lower surface of the protrusion as the inclination angle becomes steeper, and the running resistance of the belt increases, so it is necessary to increase not only wear but also the capability of the drive motor, There has been a problem that the upper part of the inclined surface moves up and down as well as in the front-back direction with the high-speed running of the belt.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and not only restricts meandering of a belt that runs while being inclined in a direction perpendicular to a conveying direction, but also prevents vertical movement of a portion above an inclined surface. It is another object of the present invention to provide a belt conveyor capable of running in a stable state while suppressing a runaway in the front-rear direction.

[0006]

In order to solve the above-mentioned problems, a belt conveyor according to the present invention is arranged such that an upper surface of a belt inclined in a direction perpendicular to a conveying direction is a mounting surface, and a conveyed object is placed on the mounting surface. A belt conveyor for mounting and transporting, wherein a linear protrusion is formed on the mounting surface of the belt over the entire length in the extension direction of the belt, and supports a peripheral surface of the protrusion. And a belt regulating means for guiding the belt in parallel with the conveying direction is provided in the conveying direction. According to this feature, since the linear protruding portion peripheral surface formed on the mounting surface of the belt is supported by the belt restricting means, the meandering of the belt running obliquely in a direction orthogonal to the transport direction is prevented. In addition to restricting, it is possible to suppress a runaway in a vertical direction and a front-rear direction in a portion above the inclined surface, and to drive in a stable state.

[0007] In the belt conveyor of the present invention, it is preferable that a protruding portion formed on the mounting surface of the belt is formed above the inclined surface. According to this configuration, since the protruding portion on the mounting surface of the belt is formed above the inclined surface, the peripheral surface is supported by the belt restricting means, so that the belt is easily lifted from the belt support plate. The site is effectively regulated.

In the belt conveyor according to the present invention, it is preferable that the belt restricting means is constituted by a roller member which holds and supports the projecting portion peripheral surface on the placing surface. With this configuration, since the peripheral surface of the protruding portion of the belt mounting surface is rolled so as to be held by the roller member, movement in multiple directions perpendicular to the traveling direction of the belt is smoothly regulated without resistance. be able to.

[0009] In the belt conveyor of the present invention, it is preferable that auxiliary rollers that hold and support the inclined lower end edge of the belt are arranged in the transport direction. With this configuration, the lower edge of the inclined belt is supported and supported by the auxiliary roller in an auxiliary manner, so that not only the abrasion of the lower surface of the protrusion formed on the back surface of the belt is reduced, but also the action on the protrusion is reduced. Load can be reduced, and the size of the drive motor can be reduced.
