Abstract

PURPOSE:To prevent a belt from such trouble as skew, deviation and slip by fitting the belt at both ends with a flexible and resilient guide rail having a fitting mouth. CONSTITUTION:Each guide rail A is made of a flexible and resilient material and equipped with an upper jaw 1, a lower jaw 2 having a ridge 3 longitudinal and a fitting mouth 4 for belt situated in the middle. The belt B fitted with such guide rails A at both ends is borne by a carrier 9, each of whose ends constituted a grooved roller 8 pressed by another respective roller 10. On the letan side, the belt B is borne by a roller 11 and pressed by a pair of grooved guide rollers 12. The pulley at the front and rear of the machine overall length is provided with grooves at both ends. This constitution should well prevent the belt from skew, deviation, slip and turnover by blast. This is also applicable to any belt device of conventional type.

Description

[Detailed Description of the Invention] This invention addresses belt meandering and uneven running that occur during operation of a belt conveyor, gusts of wind (: belt reversal and rolling,
It provides a safe and reliable belt conveyor that completely prevents conveyor troubles such as belt slippage caused by rainwater.

When a problem like the one mentioned above occurs with a belt conveyor, the conveyed objects fall to the ground, causing a lot of damage, and flowing into oceans and rivers, causing pollution and pollution, and causing pollution in people's lives and workplaces due to the scattering of dust. Causes environmental deterioration. Furthermore, due to the magnitude of the impact and the amount of loss, including cleaning costs and the loss of resources and products disposed of as garbage, we cannot ignore the issue for even one day.

Conventional technologies to prevent these problems include self-aligning carriers and belts with convex stripes integrated with the belt on the sides and center, but these techniques can cause problems such as lifting when the belt is idling, flipping the belt during gusts of wind, rolling, etc. It is completely ineffective against problems such as belt slippage caused by rainwater.

This is because in conventional vehicle techniques, vehicles are driven only by placing belts on carriers and retan rollers, and there is no compulsion to prevent troubles. In addition, providing convex stripes integrated into the belt is useful for manufacturing, transportation, and long belts.
It has not been implemented because it involves many difficulties in construction and is ineffective.

The object of the present invention is to completely prevent the above-mentioned belt troubles that could not be solved by the prior art.

Embodiments of the invention will be described with reference to the drawings.

This invention provides a guide rail A that is separate from the belt.
The guide rail A, which is made of a flexible and elastic material, has an upper rib 1, a rising rib 2 having longitudinally convex stripes 3, and a belt fitting opening 4 between the upper and lower ribs. A pulley 7 and 7' having grooves 6 at both ends installed on the machine frame 5, which is a belt with guide rails fitted on both sides, is suspended endlessly, and a grooved roller 8, which is a belt on the carrier side, is placed on both sides. The guide rail A is supported by a combined carrier 9, the guide rail A is pressed from above by a roller 10, the belt on the retan side is supported by a retan roller 11, and the guide rail person is pressed by a grooved guide roller 12 from above and driven.

When the conveyor starts and belt B runs, pulley 7.7
1 Carrier 9 Retan roller 11 and presser roller 10 Guide roller 12 rotate. In this case, the convex stripes of guide rail A that fit into the belt fit into the pulleys 7 and 71 and the concave grooves of carrier 9, and guide rail A is the presser roller 10 on the carrier side, and the grooved guide roller 1 on the lettuce side.
2, each is pressed down from the top, so belt B does not lift up. Therefore, even if the machine frame 1 is slightly distorted, no belt trouble will occur due to gusts of wind or rain, and smooth operation will be maintained.

This invention addresses belt meandering, uneven running, belt reversal due to gusts of wind, 0-ring,
Completely prevents belt slippage caused by rainwater. Since the guide rail and belt can be manufactured separately, production costs are reduced, and transportation is also easier because they can be carried out separately. It can be easily attached to a guide rail belt on site. Can be easily attached to existing conveyor belts with short stoppages. It has many excellent features such as the ability to replace and repair the guide rails if they become worn.
