BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for conveying building materials and the like, and more particularly to a transfer apparatus for construction materials suitable for a building having floors of a plurality of floors and each floor being constructed.

[0002]

2. Description of the Related Art Conventionally, as a conventional conveying apparatus for conveying building materials to each floor of a building, as a conventional example, a lifting lift installed vertically over each floor and a building from a loading / unloading port of the lifting lift are constructed. A guide track that extends to the vicinity of the place where materials should be placed, and a self-propelled carriage that has a lifting function for loading and unloading and that is capable of self-propelled along the guide track, and the lifting truck. It is known to have a command means for sending a predetermined motion signal to each of the heavy lift and the self-propelled carriage, and an input means for inputting a required motion to the command means (Japanese Patent Laid-Open No. HEI 4). 185869).

As a conventional example, both a lift rail laid in the front-rear direction from the entrance to the back on the floor of a construction lift for building high-rise buildings such as a building, and a lift and a deck along the rail. There is known a construction lift device that includes a forklift that moves in the front-rear direction over the entire length, and a pallet for building materials that is arranged on each of the decks and that is transported by the forklift to each other in a shuttle manner. (JP-A-6-171865).

However, in the above-mentioned conventional example, since the battery is mounted as the drive source of the self-propelled carriage, the self-propelled vehicle becomes very heavy and the capacity of the self-propelled cart is reduced, It was necessary to increase the pressure resistance of the floor on which the self-propelled carriage runs. In addition, since it moves around the entire floor, there is an inconvenience that obstacles and the like cannot be monitored, and there is a problem that there is a risk of contact with people and obstacles. Furthermore, since the self-propelled carriage is controlled by wireless operation, there is a possibility that the self-propelled carriage may operate or become uncontrollable due to radio wave interference or the like.

In the above-mentioned conventional example, since the forklift can only move straight ahead, it is not possible to effectively use the place where the load is placed, and when the wheel on one side of the forklift slips due to an obstacle, etc. There was a problem that I could not return to.
In addition, the plan was only to carry in the load, and the comprehensive plan up to the carry-out was not completed, and the material including dust such as waste material was not efficiently transported.

As described above, the conventional building material conveying apparatus is
There were issues to be solved in weight reduction and diversification of transport functions.

The encoders 3 and 23 are rotated in the opposite directions while monitoring the rotational speed of the drive wheels by the encoder 24 (see FIG. 10), and the skeleton portions are turned at right angles to any of the orthogonal directions with respect to the straight traveling direction.

Then, after making a right-angled turn, it goes straight along the white line, and the empty container 51a and the pallet 50 are lifted up by the lift device 29 of the transfer machine 4 in the same manner as in the above-mentioned loading work to reach a predetermined position. After moving backward, the skeleton portion of the transfer machine 4 is rotated in the opposite direction to that when the drive wheels 23, 23 are turned at the right angle, and is rotated by 90 ° so as to face the loading platform 7.

Thereafter, the transfer machine 4 is stored in the loading platform 7 of the lifting lift 2. By the bumper switch 27 of the loading platform 7, it is found that the transfer machine 4 has been stored up to a predetermined position on the depth side of the loading platform 7, and the movement of the transfer machine 4 is stopped.

Subsequently, the front doors 15 and 16 are closed by the action of the motor 13, and the footboard 18 is also flipped up.

Then, when the loading platform 7 descends the lifting lift 2 and arrives at the floor 20 on the first floor and lands on the floor within a highly accurate range, as shown in FIG. 11, the front door 15 of the loading platform 7, 1
6 is opened, the transfer machine 4 moves forward, and the empty container 51a and the pallet 50 are placed at predetermined positions in the pallet yard. This completes the work of collecting empty containers.

Further, after moving to a predetermined position on the floor 20, the pallet 50 and the containerized building material 51, which are carried in by a truck and previously placed in the pallet yard by a forklift or the like, are lifted up for the next purpose. The building materials are transported to the floor and repeated to carry in the building materials.

As described above, by simply reciprocating between the lift pallet 2 and the inside of the pallet yard of each floor 20 which is determined,
Since the transfer machine 4 does not move at a low speed in the entire range of the floor 20, the construction material transfer apparatus 1 according to the present invention can carry out the construction material loading work speedily.

The intervals of the claws 38, 39 in the lift device 29 of the transfer machine 4 can be freely changed,
Even if the trolley and the container to be conveyed have different lengths, they can be appropriately handled by operating the expansion / contraction cylinder 40.

The transfer machine 4 is also equipped with a loading platform 7 of the lifting lift 2.
Since it is driven and controlled via the cable 3 to be moved only within the pallet yard within a certain range, for example, it becomes easy to set a monitoring camera on the loading platform 7 and monitor it with the control device 5. Not only is there no need to arrange the parts, but the risk of contact with people is reduced.

Further, since the control signal is sent by the cable 3, malfunction of the transfer machine is prevented, and since the driving power is also supplied from the cable 3, it is not necessary to mount a battery on the transfer machine and the transfer is compact and lightweight. As a loading machine, the loading capacity is increased, and more building materials can be transported to the transfer machine 4. However, the weight of the transfer device 4 may be reduced and the power may be supplied to the battery, and the load range can be appropriately changed. In addition, it is equipped with a device that detects white lines and moves along with them, and the transfer machine 4 can be freely moved to a desired location by a plan plan that efficiently arranges containers and pallets in the pallet yard. It is possible to induce.

Next, in the transfer device according to the second embodiment of the present invention, the transfer device 1 for building materials according to the first embodiment is laterally moved by turning the transfer machine at a right angle. On the other hand, the driven wheels 25 and the drive wheels 23 of the frame 26 of the transfer machine 4 are rotated in the orthogonal directions by their supporting shafts by known means, and then the drive wheels 23 are rotated, thereby transferring the transfer wheels. The posture of the machine 4 is moved laterally (like walking of a crab) without rotating.

According to the transfer apparatus for building materials according to the second embodiment, even if the spaces between the pallets are narrow and the intervals between the pallets are narrow in the pallet yard, for example, the pallets are left as they are after being forked up. Since the transfer machine can be laterally moved in a posture, collision of the pallet with other building materials on the pallet due to a right-angled turn can be avoided, and work efficiency is improved.
