Description

Description: TECHNICAL FIELD The present invention relates to a pipe conveyor in which a flat belt is rolled up in a pipe shape or a U shape so that a conveyed object can be conveyed without being scattered. Is.

(Prior Art) As schematically shown in FIGS. 6 and 7, between the rollers (31) and (32) arranged at predetermined positions on the front and rear ends, an endless belt-shaped rubber conveyor belt ( 33), and at least the outward path part of the upper part is rounded upward by a number of shape-maintaining rollers (34) into a pipe shape, and a hopper (35) provided near the rear roller (32) therein. A pipe conveyer is known which wraps and conveys an object (36) to be conveyed further.

In this case, the object to be conveyed (36) is discharged, that is, dropped, when the conveyor belt (33) is inverted downward at the front roller (31).

(Problems to be Solved by the Invention) In the above-described pipe conveyor, after the pipe conveyor is once installed, the discharge point of the transported object is constant and cannot be changed.

According to the present invention, in a once installed pipe conveyor, an object to be conveyed can be freely discharged at an arbitrary position in the length direction.

(Means for Solving Problems) In the present invention, most of the upper outward path portion of the endless transport belt wound around the front roller and the rear roller is rounded into a pipe shape by a large number of shape-retaining rollers, In a pipe conveyor configured to accommodate and convey an object to be conveyed, it has an inclined surface that rises forward, an upper guide roller is provided at its front end, and a lower guide roller is provided below it. A carriage is provided so as to be movable in parallel with the upper outward path of the conveyor belt, and the upper outward path of the belt is passed over the inclined surface of the movable carriage and hung on the upper surface and front surface of the upper guide roller in a flat state. After that, the lower guide roller is made to travel toward the front roller via the rear surface and the lower surface of the lower guide roller.

(Operation) According to the pipe conveyor of the present invention, it is possible to change the dropping position of the transported object to any position in the longitudinal direction by a simple operation even after the pipe conveyor is once installed.

(Embodiment) FIGS. 1 to 5 show an embodiment in which the present invention is applied to a pipe conveyor.

(1) is the front roller, (2) is the rear roller, both of which are pedestals (3)
Installed rotatably in the required position on the front roller
(1) is adapted to be driven via a chain (5) by a motor (4) attached to the front end of the gantry (3).

An endless rubber conveyor belt (6) having a tendency to roll around the longitudinal axis is wound around the rollers (1) and (2).

Except for the front end and the rear end of the gantry (3), the height is higher than the height including the upper forward path (6a) and the lower return path (6b) of the conveyor belt (6), and A large number of support frames (7) orthogonal to the traveling direction of the conveyor belt (6) are fixed at substantially constant intervals.

As shown in FIG. 2, the support frame (7) has a pair of outer rods (7a) (7a) and inner rods (7b) (7b) whose bottom ends are located at the bottom rod (7c).
And the support plate (7d) is stretched between the inner rods (7b) (7b).

A U-shaped recessed hole (7e) having an upper opening is formed in the upper portion of the support plate (7d), and a circular hole (7f) is also formed in the lower portion.

The supporting plate (7d) is parallel to the mounting plate (7d), and the side and bottom of the recessed hole (7e) and the circular hole (7f).
Shape-maintaining rollers (8) located on the same circumference of the periphery of
The bearing (9) is pivotally attached to the bearing with the rackets (10) and (11).

The shape-maintaining rollers (8) and (9) cause the conveyor belt (6) to travel upwardly in a circular or U-shaped rounded state in the upper outward path portion (6a) thereof, and then to the lower backward path. part
In (6b), the vehicle runs in a circular state in which the side edges are on the lower side.

Straddling the upper surface of the outer rod (7a) of each support frame (7),
A longitudinal rail (12) is attached.

On the rails (12) (12), wheels (14) (15) on the lower front and rear of the moving carriage (13) are mounted. The rear wheel (15) is driven via a chain (17) by a motor (16) attached to a moving carriage (13).

The upper surface of the moving carriage (13) is an inclined surface (13a) that gradually rises toward the front, and an upper guide roller (18) is attached to the upper front end thereof.

Further, as shown in FIG. 4, a holding roller (19) forming a V shape and arranged in the left and right direction is provided at a key part of the inclined surface (13a) of the movable carriage (13).
Are installed in multiple sets.

A lower guide roller (20) is mounted between the front and rear wheels (14) and (15) in the lower part of the moving carriage (13).

As a result, the forward path portion (6a) of the conveyor belt (6) rises along the inclined surface (13a) of the moving carriage (13), and the guide roller (18)
After being flatly developed on the upper surface of the lower guide roller (20), the front surface of the lower guide roller (20) is moved to the lower rear side of the lower guide roller (20), and the lower surface of the lower guide roller (20) is moved forward. By (8), again circular or U upward
It will be rounded and run.

In addition, the upper guide roller (1
A vertical discharge tube (21) is fixed to a portion including 8). The lower part (21a) of the discharge tube (21) is divided into two left and right parts, and is open at the lower parts on both sides of the mount (3).

In the part including the front roller (1) at the front end of the frame (3),
A fixed discharge tube (22) is provided.

Immediately after the front roller (1) on the frame (3), the conveyor belt
An appropriate number of tension rollers (23) for removing the slack in the return path portion (6b) of (6) are provided.

In the pipe conveyor of the present invention having the above-mentioned configuration, regardless of the position of the moving carriage (13) on the rail (12), the upper outward path portion (6a) of the conveyor belt (6) is always the moving carriage ( After raising the sloping surface (13a) of (13) and expanding it flat,
Since it moves toward (1), the transported object (24) loaded near the rear roller (2) is discharged to the discharge tube (21) when passing through the guide roller (18) of the moving carriage (13). ) And discharged.

Therefore, the motor (16) can move the moving carriage (13) to a desired position in the longitudinal direction of the gantry (3), and in that case, the transferred object (24) can be discharged, which is convenient. is there.

Moreover, the moving carriage (13) can be moved freely even while the conveyor belt (6) is operating, which is convenient.
