[Prior art]

 Conveyed objects having various properties such as aggregates such as ore and limestone, granular materials such as beans, and powdered materials such as sugar and flour are conveyed between two belts and conveyed vertically. A so-called polymerization belt conveyor is known. In this superposed belt conveyor, a large tension is applied to two belts as compared with a normal belt conveyor, and the conveyed objects are sandwiched by the force of the belts trying to adhere to each other.

In the above-mentioned polymerization belt conveyor, the belt is transported in a horizontal direction at a lower portion where the object is supplied to the belt and at an upper portion where the object is discharged from the belt. Is formed. A vertical portion is formed between the two horizontal portions, and the two superposed belts are transported in the vertical direction. Further, the vertical portion is connected to the lower horizontal portion and the upper horizontal portion to form a lower loop portion and an upper loop portion having a predetermined radius, and the two superposed belts are transferred in an arc shape. The transition from horizontal transport to vertical transport or vice versa smoothly.

[0004] A number of carrier rollers having a predetermined trough angle are arranged on each horizontal portion and loop portion to support the belt, and a plurality of support portions for supporting the end portions of the overlapped belt are provided on the vertical portion. Edge rollers are located. Further, in addition to the rollers, the polymerization belt conveyor is provided with a roller for supporting the belt on the return side, a drive motor, and other members. Various members such as a belt, various rollers, and a drive motor that constitute the superposed belt conveyor are attached to the conveyor frame while maintaining the positions related to each other. For this reason, high rigidity and high precision are required for the conveyor frame.

[0005]

[Problems to be solved by the invention]

 The frame of the conventional polymerization belt conveyor is designed to be able to withstand the load and force acting on the frame, and is mainly composed of structural steel such as an angle material and a channel material. That is, the frame is constituted only by the section steel. For this reason, when a cover is provided according to the transported object, there is a problem that an auxiliary frame for the cover needs to be attached to the frame, which causes an increase in weight.

An object of the present invention is to provide a frame structure of a polymerization belt conveyor that can reduce the weight of the frame and reduce the number of installation steps on site to shorten the construction period.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a frame structure of a polymerization belt conveyor according to the present invention has a lower horizontal part, a vertical part, and an upper horizontal part. Frame structure of a polymerization belt conveyor for vertically transporting a plurality of unit cylinders composed of a combination of steel plates having predetermined dimensions and having a support member for supporting a belt disposed therein. The unit cylinder is disposed at a predetermined position and adjacent unit cylinders are connected to each other.

In the above frame structure, a rectangular tubular unit cylinder is formed by combining steel plates set in advance in the design stage, and a support member for supporting a belt is incorporated inside the unit tubular body. By arranging the unit cylinders vertically or horizontally and connecting adjacent unit cylinders, a frame of a polymerization belt conveyor can be constructed.

In particular, since the frame is made of a steel plate, when the superposed belt conveyor is covered with a cover, the cover material can be directly attached to the steel plate. Therefore, it is not necessary to form a frame for the cover, and the weight can be reduced.

[Embodiment of the invention]

 Hereinafter, a preferred embodiment of a frame structure of a polymerization belt conveyor will be described with reference to the drawings. 1 is a side view illustrating a frame structure, FIG. 2 is a side view showing a configuration of a vertical portion, FIG. 3 is a cross-sectional view of the vertical portion, (a) is a cross-sectional view of FIG. FIG. 2B is a sectional view, FIG. 2C is a sectional view of FIG. 2C, and FIG. 4 is a plan view for explaining a frame structure.

The polymerization belt conveyor shown in the figure is disposed below and receives a supply of a conveyed object, a lower horizontal portion 1, a lower loop portion 2 connected to the lower horizontal portion 1, and a connection to the lower loop portion 2. Vertical section 3 for transporting the transported object in the vertical direction, an upper loop section 4 connected to the vertical section 3, and an upper horizontal section 5 connected to the upper loop section 4 and discharging the transported article. A support belt 6 and a cover belt 7 are stretched from the lower horizontal portion 1 to the upper horizontal portion 5.

The support belt 6 is stretched between a head pulley 8 a driven by a drive motor 8 disposed in the upper horizontal portion 5 and a tail pulley 9 a provided in a take-up unit 9 disposed in the lower horizontal portion 1, and is provided with a cover. The belt 7 is stretched between a head pulley 10 disposed on the upper horizontal portion 5 and a tail pulley 11a provided on a take-up unit 11 disposed on the lower horizontal portion 1.

A cover belt 7 is superimposed on the support belt 6 to which the conveyed object is supplied in the lower horizontal section 1 in the vicinity of the lower loop section 2, and the cover belt 7 is transferred by contact friction, and the upper loop It is separated from the support belt 6 near the part 4. The support belt 6 is further transported in the upper horizontal portion 5 and discharges the conveyed object downstream of the head pulley 8a.

Each of the parts 2 to 5 other than the lower horizontal part 1 in the above-mentioned superposed belt conveyor has frames 12 to 15 each composed of a unit cylindrical body formed by combining steel plates having predetermined dimensions. . That is, since the lower horizontal portion 1 needs to correspond to a structure such as a hopper or a chute for supplying an object to the support belt 6, the lower horizontal portion 1 is configured to have a lower frame 16 using structural steel. However, the lower loop portion 2, the vertical portion 3, the upper loop portion 4, and the upper horizontal portion 5 are respectively composed of a lower loop frame 12, a vertical frame 13, and an upper loop frame, each of which is made of a steel-made unit cylinder. 14 and an upper horizontal frame 15.

The unit cylinders constituting each of the frames 12 to 15 have dimensions corresponding to the specifications of the target polymerization belt conveyor. In particular, the vertical portion frame 13 is formed in a symmetrical shape divided into at least two in the vertical direction. The lower loop frame 12 and the upper loop frame 14 are formed to have basically the same dimensions.

In each of the loop portions 2 and 4, a number of carrier rollers 17 having a predetermined trough angle are arranged. The carrier roller 17 is formed into a curved shape with a predetermined radius, and after assembling the loop frames 12, 14, the carrier roller 17 is attached to a curved frame 18 fixed to the frames 12, 14.

The lower loop frame 12 has unit cylinders 12a and 12b formed by combining steel plates in a U-shape, and the opposed portions of the unit cylinders 12a and 12b and the vertical part of the unit cylinder 12a. At a portion facing the frame 13, a flange 12c made of an angle material and joined to each other using bolts and nuts (not shown) is provided. The dimensions of the unit cylinders 12a and 12b are set according to the specifications of the polymerization belt conveyor and the dimensions of the transporting means. Rollers 19 on the return side excluding the curved frame 18 are attached to the unit cylinders 12 and 12b.

The upper loop frame 14 has two unit cylinders 14 a and 14 b, and is basically configured in the same manner as the lower loop frame 12. The difference between the two frames 12, 14 is that the vertical dimensions are different. That is, the height of each of the frames 12 and 14 is set so that the lower loop frame 12 is set such that the conveying surface height of the support belt 6 is based on the floor surface, whereas the upper loop frame 14 is specially designated. This is due to the absence.

Accordingly, it is not impossible to share the unit cylinders 14 a and 14 b constituting the upper loop frame 14 with the unit cylinders 12 a and 12 b constituting the lower loop frame 12, but this is not a good idea. Further, flanges 14c to be joined to each other are provided at opposing portions of the unit cylindrical bodies 14a and 14b and at portions opposing the vertical frame 13 and the upper horizontal frame 15, and a return side other than the curved frame 18 is previously provided inside. Rollers 19 are attached.

The vertical frame 13 has two unit cylinders 13 a formed symmetrically, and a portion of the unit cylinder 13 a opposed to the unit cylinder 13 a and a portion opposed to each of the loop frames 12, 14. Each of the positions is provided with a flange 13b which is joined to each other.

As shown in FIGS. 3 (a) to 3 (c), the vertical portion 3 has an edge roller 20 abutting on the non-conveying surface of the overlapped support belt 6 and cover belt 7 and the end in the width direction. A backup roller 21 is disposed in contact with the center side, and further, rollers 19 on the return side are disposed. The edge roller 20 and the backup roller 21 are mounted on a roller frame 22 at a predetermined pitch.

The roller frame 22 provided with the rollers 19, the edge rollers 20, and the backup roller 21 disposed on the vertical section 3 is previously mounted on each unit cylinder 13 a constituting the vertical section frame 13.

The upper horizontal section frame 15 has a unit cylinder 15a formed to have the same dimensions as the unit cylinder 14b of the upper loop section frame 14. A flange 15b is provided on a portion of the unit cylindrical body 15a opposed to the upper loop frame 14 to be joined to each other.

Each of the unit cylinders uses a steel plate having at least two surfaces having a thickness set in advance in a design stage. For this reason, when it is necessary to cover the polymerization belt conveyor with a cover, it is possible to attach a cover material to each unit cylinder without providing a special frame.

Further, when configuring the polymerization belt conveyor, it is possible to assemble by arranging the unit cylinders constituting each of the frames 12 to 15 in order and joining them via flanges. By attaching rollers to each unit cylinder in advance, it is possible to assemble the polymerization belt conveyor simultaneously with the joining of each unit cylinder.
