Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial field of application) The present invention is designed to slidably receive and support the lower surface of a material feeding portion of a belt with a cushioning member formed of a sheet-shaped member. Concerned belt conveyor.

(Prior Art) A general configuration of a belt conveyor is to stretch a belt made by laminating a cloth and a rubber layer between a driving vehicle and a driven vehicle,
The belt is supported by a large number of rollers between these two cars, and bearings are built into these rollers, so that when handling heavy rocks as a cargo, for example, from the hopper to the belt. There was a high possibility that the drop cushion of the rocks supplied would damage the bearings of the rollers located below the material supply site of the belt. Therefore, in order to prevent this, only the lower side of the material supply portion is arranged so that wooden plates or columns are arranged instead of the rollers to receive and support the belt.

(Problems to be solved by the invention) However, in the structure of receiving and supporting the belt with wood,
There is a drawback that the belt is apt to be damaged and has a short life because the belt is in a state of being pressed between the rock and the wood due to an impact caused by falling of the rock.

In addition, the conventional belt conveyor, at the site where the material is to be conveyed, when rocks fall from both sides of the belt at the upper feed position, the rock conveyor moves on the belt at the lower return position and moves as it is. Since it was caught between the subordinate (driving) vehicle, it damaged the belt and caused damage such as cutting.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to mitigate a drop impact of a conveyed product exerted on a belt at a portion where the conveyed material is supplied, and at the same time, to convey the conveyed material laterally from the belt at this portion. It is an object of the present invention to provide a belt conveyor which can prevent spillage and thus can prolong the life of the belt as a whole.

[Configuration of the Invention] (Means for Solving the Problem) The present invention is directed to a main body of a belt conveyor including a belt, a belt supporting mechanism, and a belt driving mechanism, and a flexible sheet-shaped member having a width. Is set to be wider than the width of the belt and has a predetermined length dimension in the longitudinal direction of the belt, and is provided so as to suspend and support both edge portions in the width direction of the cushion member. The present invention is characterized in that it is configured to include a support means for slidably receiving and supporting the lower surface of the transported material supply site by the buffer member.

(Operation) The belt driven by the drive mechanism is slidably received and supported on the lower surface of the transported material supply portion by the cushioning member having both edges in the width direction suspended and supported by the supporting means. There is. For this reason, the shock of dropping the carried article exerted on the belt at the article supply site is absorbed and relaxed by the cushioning member.

Further, since the width of the cushioning member is wider than the width of the belt, even if the cargo to be fed at the cargo feeding portion overflows from both ends of the belt, it is received by the cushioning member and returned to the belt. , No more spilled items on both sides of the belt.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

On the other hand, 11 is a cushioning member that slidably receives and supports the lower surface of the belt 6 at the transported material supply site A, which is made of a flexible rectangular sheet material, and is made of synthetic fiber like the belt 6, for example. It is made by laminating a cloth and a synthetic rubber layer. The width dimension thereof is wider than the width of the belt 6, and the length thereof is set to be substantially equal to the length of the transported material supply site A. 12
Is a plurality of strips fixed to the upper surface of the cushioning member 11 at predetermined intervals along the moving direction of the belt 6, for example, 6
A strip-shaped antifriction member of a strip, which is made of a polymer material such as polyethylene terephthalate having excellent wear resistance and a small friction coefficient.

Reference numeral 13 is a support metal fitting fixed to both edge portions in the width direction of the cushioning member 11, and a plurality of, for example, four hanging bolts 14 are projectingly provided on these at a predetermined interval. Reference numeral 15 denotes a pedestal fixed on the frame 1 so as to face the conveyed material supply site A of the belt 6, and three columns 17 are erected on both edges of the pedestal 16 and the top ends of these columns 17 are provided. A fixing member 18 is provided so as to connect with each other. This fixing member 18
The hanging bolts 14 provided on the cushioning member 11 via the support fittings 13 are respectively inserted into the bolt through holes 18a provided on the. The antifriction member 12 fixed to the cushioning member 11 is in sliding contact with the lower surface of the belt 6 as shown in FIG. In this way, the cushioning member 11 that receives and supports the belt 6 is in a state in which both side portions 11a, 11a in the width direction of the cushioning member 11 protrude from both side ends of the belt 6, respectively. Here, the support fitting 13, the suspending bolts 14, and the pedestal 15 constitute a supporting means 30 for suspending and supporting both widthwise edges of the cushioning member 11. In addition, each pillar 17 has a structure in which its height can be adjusted in a sliding manner.

Next, the operation of the above configuration will be described.

The drive wheel 4 is rotated by a drive motor (not shown) to move the belt 6, and the belt 6 is supported by the buffer member 11 at the article supply portion A, and the other portions are supported by the carrier roller 7 and the return roller 8. Has been done. On the other hand, the material supply site A from the hopper 10 to the belt 6
The rock (B) supplied to the

As described above, according to the above configuration, the shock absorbing member 11 reduces the impact of the fall of the conveyed product on the belt 6 at the conveyed product supply portion A, so that the belt 6 is surely prevented from being damaged and cut. To be done. Further, since the transported material supplied onto the belt 6 does not spill, the spilled transported material may be caught between the secondary (driving) vehicle and the belt 6 to cut the belt 6 as in the conventional case. As a result, the life of the belt 6 is extended as a whole.

5 to 8 show another embodiment of the present invention,
The same parts as those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted. Only different parts will be described below. That is, the opposing intervals of the three columns 17 respectively provided on both sides of the platform 16 of the gantry 15 are closer to the downstream side (the right side in FIG. 5) in the moving direction of the belt 6 and are closer to each other. In addition to narrowing the facing distance, each of the fixing members 21, 21 provided on each column 17 is also narrowing the facing distance toward the right side. Therefore, the width of the gutter-shaped opening of the cushioning member 11 becomes narrower toward the right side, and the belt 6 is deformed when the cushioning member 11 moves to match the shape of the cushioning member 11.

Next, the operation of this embodiment will be described with reference to the drawings. In the rock B supplied from the hopper 10 onto the belt 6, the rock 6 is moved to the right in FIG. As it approaches, the belt 6 is gradually deformed into the shallow gutter shape, which is shown in FIG.
The rocks B that have spread upward are gathered toward the central portion of the belt 6 as illustrated. And belt 6
When the belt passes through the supporting area by the buffer member 11 and reaches the position supported by the carrier roller 7, the belt 6 moves to the eighth position.
As shown in the figure, the shape returns to the shallow gutter shape, but at this time, the rock B on the belt 6 is kept gathered in the central portion of the belt 6 as shown in FIG. Therefore, there is no possibility that the rock B spills from both side edges of the belt 6 while the belt 6 continues to move with vibration thereafter.

It should be noted that the purpose of the present invention can be achieved by appropriately changing the material of the cushioning member 11 and the structure of the support fitting 13 in each of the above-mentioned embodiments, and the structure of the main body 9 of the belt conveyor is of course the same as in the above-mentioned embodiments.
