[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a twist correction device for a pipe conveyor, and more particularly, to a twist of a pipe conveyor for correcting a twist in a traveling direction of a conveyor belt by adjusting a mounting angle of a shape retaining roller. It relates to a straightening device.

[0002]

2. Description of the Related Art Conventionally, as a system for transporting powdered or granular conveyed objects, scattering or spillage occurring during the transportation of conveyed objects is effectively prevented, and a flat line is required for a line requiring curve transportation. 2. Description of the Related Art Pipe conveyors in which a belt is rolled into a pipe and transported are known. The conveyor belt of this pipe conveyor is in the form of a flat belt when an object is placed or transferred, and is formed on the support plate 1 as shown in FIGS. 4 and 5 during operation. The conveyor belt 4 is sequentially inserted inside a plurality of shape-retaining rollers 3 arranged on the peripheral edge of the hollow portion 2 to form a pipe.
Is transported in a wrapped state, and is returned to a flat belt shape again at the time of discharge.

The above-described pipe conveyor has no constraining means when it is transported along the support plate 1 provided with the shape-retaining rollers 3, so that the conveyor belt 4
Of the conveyor belt 4
a), the conveyor belt 4 comes into contact with the roller bracket 5 or the like, damaging the belt end,
There is a problem that the transported object W falls off.

Therefore, conventionally, when the conveyor belt 4 is twisted, for example, Japanese Patent Publication No.
As shown in FIG. 1 and FIG. 6, the roller bracket 5 is inclined by interposing a spacer 6 between the roller bracket 5 of the shape retaining roller 3 and the support plate 1, and the shaft portion 7 of the shape retaining roller 3 is formed. As shown in FIGS. 7 and 8, a method of adjusting the angle θ, the mounting hole 8 of the shape retaining roller 3 formed in the roller bracket 5 is formed in a long hole, and the angle of the shaft portion 7 of the shape retaining roller 3 is adjusted. Is adjusted in the up-down direction via bolts 9.

[0005]

However, when such a spacer 6 is interposed, it is necessary to always prepare spacers 6 of various thicknesses and to remove a plurality of mounting bolts to maintain the shape. Since the roller 3 must be removed together with the roller bracket 5, the workability is poor, and there has been a problem that the adjustment work requires much labor and time.

In the case where the elongated mounting hole 8 is formed in the roller bracket 5, there is a problem that the cost is increased because extra work is required in processing. This invention was devised in view of such a conventional problem, and when the conveyor belt is twisted, the mounting angle of the shape retaining roller can be easily changed in any direction without using other members. Further, it is an object of the present invention to provide a pipe conveyor torsion straightening device which can be easily fine-adjusted and has improved workability and safety.

[0007]

According to the present invention, in order to achieve the above object, an L-shaped cross section for supporting the roller bracket (5) is formed on a vertical support plate (1) around the hollow portion .
Attach the vertical side (10a) of the support bracket (10)
Concave section on the other horizontal side (10b) of the support bracket (10)
Place the bottom surface of the roller bracket (5) formed on the surface of the roller bracket (5), and contact one side of the contact surface between the roller bracket (5) and the support bracket (10) with at least two or more rollers in parallel with the conveyor belt conveyance direction. Forming a slot (12) and the other slot (12)
The engagement and fixable mounting bolt (13) in provided, the
Adjust the mounting angle of the shape retaining roller (3) to the roller bracket (5).
The gist of the present invention is that it can be adjusted from the lower side . The support bracket is detachably provided on the support plate via a mounting member, or provided integrally with the support plate.

[0008]

The present invention is configured as described above, and when the conveyor belt is twisted, the support bracket is used.

The work can be done efficiently in a short time.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The same components as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted. FIG. 1 is a side view of a device for correcting the twist of the shape-retaining roller 3 in a pipe conveyor embodying the present invention, wherein 4 is a rounded conveyor belt supported by the shape-retaining roller 3 and 1 is for attaching the shape-retaining roller 3. As shown in FIGS. 2 and 3, the support plate 1 has a support bracket 10 formed in an L-shaped cross section.
Is attached via mounting bolts 11.

On the other side 10b of the support bracket 10, a conveyor formed in an arc shape or an eye larger than the bolt is provided.
Elongated holes 12 are formed at predetermined intervals in parallel with the transfer direction of the belt, and the elongated holes 12 formed in the other side 10b of the support bracket 10 have roller brackets 5 having a concave cross section for supporting the shape-retaining roller 3. The mounting bolts 13 vertically provided on the bottom surface are inserted and fixed with the fastening nuts 14.

It is to be noted that a long hole 12 may be formed in the roller bracket 5 and a mounting bolt 13 may be provided on the support bracket 10. Further, in this embodiment, the support bracket 10 is attached to and detached from the support plate 1 via the mounting bolt 11. Although mounted as possible, the support bracket 10 may be integrally fixed to the support plate 1. Next, a method of correcting the twist of the pipe conveyor by adjusting the mounting angle of the shape keeping roller 3 when the twist of the conveyor belt occurs will be described.

[0012] First, if the twisting of the conveyor belt occurs, the fastening nut 14 of the mounting bolts 13 it
Each loosened, the roller bracket 5 to the support bracket 10
The shaft 7 of the shape-retaining roller 3 is slid along the two elongated holes 12 formed in parallel with the conveying direction of the conveyor belt so that the angle θ of the shaft portion 7 becomes a predetermined angle. And the shape-retaining roller 3
When the adjustment of the mounting angle θ is completed, the loosened tightening nuts 14 are tightened and fixed, respectively, so that the mounting angle θ of the shape retaining roller 3 can be adjusted in an arbitrary direction.

As described above, in the embodiment of the present invention, when the conveyor belt is twisted, unlike the conventional case, the members such as the spacers are not used, and the shape retaining roller 3 and the roller bracket 5 are removed. In addition, the adjustment work can be performed easily and in a short time, and workability and safety can be improved.
