DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material transfer facility at a construction site suitable for carrying long materials through narrow spaces.

[0002]

BACKGROUND OF THE INVENTION Generally, there are no vacant lots for stocking materials at construction sites in urban areas, and even if there are some finishing materials, they cannot be exposed to rain.

[0003] Therefore, at a construction site under construction of this kind, a hall connected to the entrance of a building such as a lobby on the ground floor or an entrance hall is used as a stock yard for materials, and a material is stored by using a main elevator shaft. Lifting is being carried out.

[0004]

However, in general, as shown in FIG. 1, an elevator hall 2 in which a permanent elevator shaft 1 is installed is adjacent to a hall 4 via a wall 3 as shown in FIG. If the width w of the entrance / exit opening 5 for communicating the wall 3 with the hall 4 is particularly smaller than the width W of the long material 6, the material 6 cannot be transported while being mounted on the forklift 7. . Originally, the forklift 7 has a structure in which a fork is applied to a central portion of the material 6 in the longitudinal direction to lift the material 6, and travels perpendicular to the longitudinal direction of the material. Therefore, in a building of this type,
When the long material 6 is carried into the elevator hall 2, the forklift 7 is turned by 90 ° from the state shown in the figure, and the material 6 is supplied to human power or a hoist in a state where the longitudinal direction of the material 6 faces the opening 5. 6 has to be transferred and passed through the opening 5 and brought into the elevator hall 2, resulting in a drawback that the loading operation takes time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to change a complicated direction when transferring a long material to a carry-in position through a narrow passage such as an entrance or a corridor. An object of the present invention is to provide a material transfer facility at a construction site which can be performed without any work.

[0006]

In order to achieve the above-mentioned object, the present invention relates to a material transporting apparatus used for loading a building under construction having a narrow passage opening between a stockyard and a loading position. The transport equipment is located in the stock yard, and the transport terminal is disposed orthogonal to the passage opening, and the longitudinal direction of the long material is placed orthogonal to the transport direction. A roller conveyor for transferring the material, and a reciprocating transport vehicle that is located at the end of the roller conveyor, receives the long material in its attitude, and moves in and out of the loading position through the passage opening by lateral movement. It is characterized by having.

[0007]

According to the above construction, the long material transferred from the stock yard by the roller conveyor is received by the carrier as it is, and is carried into the carry-in position through the passage opening by the lateral movement of the carrier. You.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the method of the present invention will be described below in detail with reference to the drawings.

FIG. 2 is a perspective view showing the transfer equipment of the present invention, and FIG. 3 is a plan view of the same. Since the building structure in the figure is the same as that of the related art, the common parts are denoted by the same reference numerals, and only different points will be described using different reference numerals.

That is, the building to which the present invention is applied has a structure in which the elevator hall 2 in which the main elevator shaft 1 is installed is adjacent to the hall 4 with the wall 3 interposed therebetween. The width w of the entrance / exit opening 5 for communicating with the material 4 is particularly smaller than the width W of the long material 6.

The hall 4 is a stock yard for the material 6, and a roller conveyor 10 for transporting the material is arranged in the hall 4 so that the longitudinal direction of the material 6 is perpendicular to the direction of the material transport. The transfer end of the roller conveyor 10 is arranged orthogonally to the entrance opening 5 and on its extension.

An unmanned transport vehicle 12 is arranged at the transport end of the roller conveyor 10. The transport vehicle 12 is an electric traveling vehicle that reciprocates in a lateral direction along an induction tape 14 attached to a floor surface, and the tape 14 is moved from the vicinity of the end of the roller conveyor 10 through the opening 5 to the elevator shaft of the elevator hall 2. 1 is laid in a straight line up to the floor near the opening, and the carrier 12 reciprocates along the floor.

The surface of the transport vehicle 12 facing the roller conveyor 10 is a surface on which the material 6 is placed. A fork is provided at the center of the surface, and the material 6 is transported in a state facing the terminal end. Take it in the posture. Note that, of course, the entire width of the transport vehicle 12 is sufficiently smaller than the width w of the entrance opening 5, and the installation surface is set to a length that supports the entire length of the material 6 in the longitudinal direction.

Further, as shown in FIG. 3, a transfer device 16 is arranged in the elevator hall 2 and in the elevator shaft 1. The transfer device 16 is provided with a fork for receiving the material 6 at the transfer end position of the transport vehicle 12, and a material lifting gondola 18 that rises and lowers inside the elevator shaft 1 at right angles to the moving direction of the transport vehicle 12. It reciprocates between the inside and the hall 2.

In the above configuration, the roller conveyor 10
The long material 6 placed on the
It is delivered to the automatic guided vehicle 12 waiting here with its posture.

The transport vehicle 12 which has received the material 6 moves into the elevator hall 2 through the entrance / exit opening 5 by lateral movement and stops just before the opening surface of the elevator shaft 1 which is the transport end position.

At the stop position, the transfer device 16 receives the material 6. The unmanned guided vehicle 12 in the empty state is the entrance 5
Through the roller conveyor 10 side.

The transfer device 16 moves through the opening of the elevator shaft 1 while supporting the material 6 to move the gondola 1.
Stop in 8. The frontage of the gondola 18 is long enough to receive the long material 6. In this state, the gondola 18 is lifted to the construction floor by lifting.

The transfer device 16 which has delivered the material 6 on the construction floor
Moves into the gondola 18 again and descends to its original position,
When the opening surface of the elevator shaft 1 is opened, the elevator shaft 1 moves from the gondola 18 to the standby position again and stops.

Therefore, the material 6 is successively lifted to the construction floor by repeating the above-described transfer and transfer operations.

[0021]

As explained in detail in the above embodiments, in the material transporting equipment at a construction site according to the present invention, a long material transported from a stock yard by a roller conveyor is transported as it is. It is picked up by the car and transported to the carry-in position through the passage opening by the lateral movement of the carrier, allowing long materials to pass through the narrow opening without changing the attitude of the material, making transfer work easy. Can be done.

Therefore, the present invention is suitable for, for example, a case where it is necessary to pass through a narrow place such as an entrance or a corridor depending on a building structure when lifting using a built-in elevator shaft.
