Description

  The present invention relates to a belt conveyor, and more particularly to a belt conveyor that is suitably used when there is a height difference between an upstream side and a downstream side of a conveyance path.

  Conventionally, a belt conveyor has a base installed along the transport path between the upstream side and the downstream side of the transport path of articles, and a pulley is installed between the upstream end and the downstream end of the base. An endless belt-like conveyor belt is wound around these pulleys, and a plurality of guide rollers for supporting the conveyor belt at a plurality of locations in the conveying direction and suppressing blurring of the conveyor belt are provided. The structure is mounted on the gantry.

  By the way, in the above-described belt conveyor, there may be a case where a difference in height is required between the carrying-in position and the carrying-out position of the article to be conveyed. For this purpose, the belt conveyor is configured such that one end thereof is higher than the other end. Must be installed in.

  In order to cope with such a belt conveyor installation mode, conventionally, for example, a countermeasure as disclosed in Patent Document 1 is performed.

  In the technique disclosed in Patent Document 1, a support structure is formed on the floor on which the belt conveyor is installed, and the belt conveyor is supported by supporting one end of the belt conveyor. It is installed in an inclined state.

  On the other hand, as another method of installing the belt conveyor in a state where the height difference is provided at both ends, it is conceivable to incline the floor surface on which the belt conveyor is installed.

Japanese Utility Model Publication No. 5-77112

  By the way, in the technique described in the said patent document 1, since it is necessary to construct | assemble a support structure, it causes a rise in installation cost, and since the period of the installation operation | work of this support structure is required, it is installed. There is a problem that the construction period for the project becomes longer.

  In addition, in the latter method of inclining the floor surface, since the floor is usually formed of concrete, when concrete is placed, the concrete must be placed so that the top surface is uniformly inclined. Therefore, there is a problem that the construction becomes extremely difficult work.

  The present invention has been made as a solution to the above-described problems of the prior art, and when installing a belt conveyor with a difference in height at both ends of the conveyance path, the construction is simplified. This is a problem to be solved.

  In order to solve the above-described problems, the belt conveyor of the present invention is configured such that a plurality of gantry components are arranged in series along the conveying direction of the belt conveyor, and the gantry of the adjacent gantry components is arranged. The end portions are connected to each other via a connecting tool, and the connecting tool is attached to the end of one of the adjacent gantry constituting bodies and the end of the other gantry constituting body. A second connecting tool to be fixed, a fixing means for fixing the first connecting tool and the second connecting tool to the gantry constituting body, and the first connecting tool and the second connecting tool are rotatably connected. And a connecting shaft.

By setting it as such a structure, a some conveyance structure can be formed by connecting a some mount structure with a connector.
And by rotation of the 1st connection tool and the 2nd connection tool which comprise a connection tool, the other mount structure can be connected in the state which made the angle with respect to one connected mount structure.

Here, by making the connecting shaft horizontal, the other gantry constituting body can be tilted up and down with respect to the one gantry constituting body.
Thereby, a height difference can be provided between the unconnected end portions of one gantry constituent body and the other gantry constituent body.

Thus, the inclination of the gantry structure can provide a height difference between the unconnected end portions of one gantry structure and the other gantry structure, so that the floor on which these gantry structures are installed The surface can be horizontal and the floor can be stepped.
That is, one connected frame structure is installed on a horizontally formed high floor, and the unconnected end portion side of the other frame is placed on a horizontally formed low floor. By doing so, it is possible to install the gantry structure while ensuring the above-described height difference by positioning the other unconnected end portion at a low position with respect to the one gantry structure.

Therefore, the shape of the floor is simplified, and the construction for constructing the floor can be simplified.
In addition, since the work can be performed on a horizontal floor when installing the gantry structure, the work can be simplified.

  One end portion of the first connector is disposed so as to protrude from an end portion of the one frame structure, and one end portion of the second connector is disposed so as to protrude from an edge portion of the other frame structure. The protruding end portions of the first connector and the second connector are preferably overlapped in a direction substantially orthogonal to the transport direction, and the connecting shaft is mounted on the overlapping portion.

  By setting it as such a structure, connection with a 1st connection tool and a 2nd connection tool can be performed in the exterior of a mount frame structure, and the connection operation | work can be made easy.

  On the other hand, the frame structure can be connected on the same plane to form a horizontal conveyance path.

  In addition, by preparing a plurality of gantry structures having different lengths and appropriately selecting and connecting them, the length of the conveyance path formed by these gantry structures can be easily adjusted. Therefore, it is possible to easily form a conveyance path having a required length.

  The fixing means includes the first connector and the gantry structure, the second connector and a fixing bolt that passes through the gantry structure, and the first connector and the first connector screwed to the fixing bolt. The two connecting tools can be constituted by a fixing nut that press-contacts the frame structure.

  By setting it as such a structure, the said fixing means can be attached or detached and it can mount | wear only at a required location.

  Further, the fixing means is a backing material that is disposed in a portion of the gantry constituting body opposite to the portion where the first connector or the second connector is disposed, and through which the fixing bolt penetrates. It can be set as the structure provided with.

  By setting it as such a structure, the fixing force by the said fixing means can be uniformly disperse | distributed to the said mount frame structure body, and the stable fixing force can be obtained.

  In the first connector, a long hole is formed along the length direction of the gantry structure, and a protrusion that fits into the long hole is formed in the gantry structure to which the first connector is fixed. It can be set as the formed structure.

  By adopting such a configuration, the displacement between the first connecting tool and the gantry constituent body is suppressed by the fitting of the elongated hole and the protrusion, and the shift of the connecting portion of the two gantry constituent bodies is suppressed. can do.

  And when it is set as the structure by which the contact surface with which the inner surface of the said long hole is contacted is formed in the said protrusion, when position shift arises between the said 1st coupling tool and a mount structure, The displacement of one connector can be received by the contact surface, and the above-described positional displacement can be effectively suppressed.

  According to the belt conveyor of the present invention, the floor surface to be installed can be constructed in a horizontal state, and even when it is necessary to provide a height difference at both ends of the belt conveyor, the floor surface is formed in a stepped shape. It can be handled by easy construction.
