Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roller support structure in a pipe conveyor, and more specifically to a roller support structure capable of easily adjusting an angle of a shaft portion of a holding roller with respect to a traveling direction of a conveyor belt. is there.

[0002]

[Prior Art]

 Conventionally, as a system for transporting powdered or granular objects, flat belts can be piped to lines that require curb transportation to effectively prevent scattering and cargo spillage that occur during transportation. A pipe conveyor that is rolled into a shape and transported is known. This pipe conveyor is in the shape of a flat belt when placing or transferring an object to be transported, and inside a holding frame equipped with holding rollers arranged in a hollow circle during operation. It is a system in which the objects to be transported are rolled into a circular pipe shape while being sequentially inserted into the container, and the transported object is returned to the flat belt shape when discharged.

By the way, in the pipe conveyor as described above, when it is transported along the holding frame having the holding rollers, the belt is twisted because it does not have any restraining means, and the belt is piled up. In addition, the parts may be up and down or may be slanted, which causes problems such as damage to the belt and dropping of transported objects.

[0004]

[Problems to be solved by the device]

 Therefore, conventionally, when the belt is twisted, the shaft portion of the holding roller is adjusted in the traveling direction of the belt so that the force is generated in the direction opposite to the belt twist. As means for adjusting the twist of the belt W, conventionally, for example, as shown in Japanese Patent Publication No. 1-46404 and FIGS. 2 and 3, between the bracket 2 of the holding roller 1 and the roller holding plate 3, The angle θ of the shaft portion 5 of the holding roller 1 is adjusted with the spacer 4 interposed.

However, in the case of the method of interposing the spacer 4 as described above, it is necessary to always prepare the spacers 4 having various thicknesses, and the adjustment work for operating the plurality of bolts 6 is performed. There was a problem that it took a lot of time and effort. The present invention has been devised in view of such conventional problems. When the belt is twisted, it can be easily adjusted without using a member such as a spacer, and the workability and the operation are improved. It is an object of the present invention to provide a roller support structure for a pipe conveyor having good performance.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, this invention fixes a bracket having a U-shaped cross section to a holding plate on which a plurality of holding rollers are mounted, and at least one side plate of the bracket has a bolt planted along the bolt. The gist of the present invention is that a key plate having a slidable elongated hole is provided and the key plate is configured to support both end shaft portions of the holding roller.

[0007]

[Function of the device]

 The present invention is configured as described above, and when a twist of the belt occurs, the position of the key plate that can slide along the bolt is simply adjusted, and the shaft portion of the holding roller is adjusted in the traveling direction of the belt. The angle can be easily adjusted, and the adjustment work will be easy.

[0008]

[Example of device]

 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view of a roller support structure in a pipe conveyer embodying the present invention, FIG. 2 is a side view taken along the line AA of FIG. 1, 10 is a belt rolled into a pipe, and 11 is a plurality of belts. 2 shows a holding plate to which the holding roller 12 is attached. The holding roller 12 is rotatably arranged at a peripheral portion of a hollow portion formed in the holding plate 11 at a predetermined interval.

A bracket 13 having a U-shaped cross section is fixed to each of the holding plates 11 to which the plurality of holding rollers 12 are attached, and a bolt 14 is planted on at least one side plate 13 a of the bracket 13. . An elongated hole 16 formed in the key plate 15 is slidably fitted in the bolt 14, and is fixed by tightening the bolt 14 and the nut 17. On both ends of the key plate 15, both end shaft portions 18 of the holding roller 12 are supported.

With such a configuration, when the belt 10 is twisted during transportation and the angle of the shaft portion 18 of the holding roller 12 with respect to the traveling direction of the belt 10 needs to be adjusted, The angle θ of the shaft portion 18 can be easily adjusted only by loosening the nut 17 and sliding the position adjustment of the oblong hole 16 of the key plate 15 along the bolt 14, and the nut 17 can be easily adjusted after the adjustment. The work can be completed simply by tightening and fixing.

[0011]

[Effect of the device]

 In this invention, a bracket having a U-shaped cross section is fixed to a holding plate to which a plurality of holding rollers are mounted as described above, and a bolt is planted on at least one side plate of the bracket and slides along the bolt. A key plate with a movable long hole was provided, and the key plate was configured to support the shafts of both ends of the holding roller, so that the belt was twisted, and the angle of the shaft of the holding roller was adjusted. Even if it becomes necessary, it is possible to easily make adjustments without using conventional members such as spacers, and to improve workability and operability in adjusting the angle of the shaft. There is.
