Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a conveyance device for conveying various materials brought into a construction site to a construction zone, etc. The present invention relates to a conveyance device that automatically conveys to a person.

(Conventional technology) Building production has unique characteristics that are different from other industrial production.

For example, in principle, only one building is produced based on one design, and the production is carried out outdoors, and the production system is such that multiple subcontractors work simultaneously in different construction areas. There is.

In addition, materials used in construction work are delivered to the construction site by large trucks, etc., depending on the construction plan and construction status of the construction work, and the delivered materials are transported to a predetermined stockyard, or They are transported to various construction areas where finishing and other construction work is being carried out.

Conventionally, such materials have generally been transported manually during working hours using work vehicles such as forklifts and lifting lifts.

(Problem to be solved by the invention) In such a conventional material transportation method, when materials brought into the entrance of a construction site are transported separately for each destination such as a work zone or stockyard, it is difficult to adjust the construction plan. A person in charge of materials management is required to be familiar with the process chart created according to the schedule, and in order to avoid mistakes in transporting materials, it is necessary to clearly indicate the transport destination on the materials or use a shipping tag with the transport destination written on it. It is necessary to paste.

However, such work places a heavy burden on the person in charge and is time-consuming, and is also prone to errors in the destination.

In addition, when transporting materials to a destination, transport vehicles such as forklifts and lifting lifts are used, but since most of these operations are done manually, the destinations are distributed over multiple floors. When transportation destinations become diverse, the number of workers engaged in transportation increases, leading to an increase in transportation costs.

Furthermore, in construction production, various types of construction work are carried out simultaneously based on schedules, so large amounts and types of materials are brought in in a concentrated manner.

This has led to problems such as forklifts, lifting lifts, and other transport machinery being competed with by construction companies contracted for each construction area, reducing the efficiency of transporting materials, hindering actual construction work, and disrupting the work process. There was a problem of stagnation.

The present invention has been made in view of the above-mentioned points, and it is an object of the present invention to provide a construction material transport device that can automatically transport materials delivered to a construction site to a predetermined work position using a small number of transport machines. With the goal.

As is well known, the automatic guided vehicle 16 is equipped with running wheels, a steering wheel, and a drive motor for driving these (none of which are shown), and furthermore, the automatic guided vehicle 16 is equipped with running wheels, a steering wheel, and a drive motor for driving these (none of which are shown).
It has a control circuit 16a that automatically controls the operation of the vehicle.

Moreover, a transfer device 26 of a roller conveyor portion is installed on the automatic guided vehicle 16 to transfer the materials 21 placed on each pallet in a predetermined direction. This transfer device 26 drives a roller conveyor section using a built-in drive mechanism, thereby making it possible to place the materials 21 carried in on the transfer device 26 and to automatically carry them out to the cargo receiving cart at the cargo storage position. .

The automatic guided vehicle 16 configured in this manner is used to transport materials 21 brought into the first floor of a building to each floor other than the first floor in collaboration with the lifting lift lO, and for this purpose, 1
At the landing of the floor IF of the floor, the automatic guided vehicle 16 is placed in the landing car 1.
A taxiway 27 for reciprocating guidance is formed between 2 and 2F, and a guideway 27 is formed on each floor 2F=nF above the second floor to allow the automatic guided vehicle 16 to run unmanned between the landing entrance of each floor and the stockyard (cargo storage area). Semi-fixed taxiways 282 to 2B are laid. Furthermore, a guide path 29 is provided on the floor of the car 12 for automatically getting on and off the automatic guided vehicle 16.

As shown in FIG. 2, the automatic guided vehicle 16 includes a barcode league 30 for reading the barcode tag 21b attached to the material 21 or its pallet 21a, and a transceiver for transmitting and receiving signals with the transceiver 23 of the car 12. 31 are installed respectively.

The barcode sheet 2)b indicates the destination of the material 21, and specifies the destination floor for the lifting lift 10, and specifies the cargo storage location for the automatic guided vehicle 16.

On the 1st floor floor IF (ground floor), there is a semi-fixed guided dew 33 that connects the stockyard 32 where various materials 21 to be brought in are temporarily stocked and the standby position 2 of the automatic guided vehicle 16.
A forklift 3 is installed along this taxiway 33.
4 are arranged so that they can run automatically.

This forklift 34 has a built-in optical sensor (not shown) at the tip of a pair of fork claws that handle the material 21.
This optical sensor determines the presence or absence of a pallet to ensure cargo pickup, and a barcode league (not shown) reads the barcode tag 21b attached to the material 21 or its pallet 21a and displays it on a monitor. This makes it possible for anyone to understand the information about the object to be transported (date, time, product name, quantity, place of use, and user).

In addition, in the stockyard on floors 2F to nF other than the first floor (ground floor), a loading cart 35 for temporarily storing materials 21 is arranged. The materials 21 that are received can be stocked on each pallet.

Next, the operation of this embodiment configured as described above will be explained.

First, when the forklift 34 starts operating, it takes out one material 21 (7) stacked in the stockyard 32 along with the pallet 21a.

Then, after reversing the direction of the load side to the traveling side, the automatic guided vehicle automatically travels along the guideway 33 to the automatic guided vehicle standby position P.

When the forklift 34 reaches the running end of the taxiway 33,
The presence of each other is confirmed by an optical sensor or the like, and if the presence of each other is confirmed, the material 21 on the forklift 34 is placed on the transfer device 26 on the automatic guided vehicle 16. At the same time, the roller conveyor section of the transfer device 26 is driven to transfer the material 2.
1 to the determined position and hold it.

Thereafter, the automatic guided vehicle 16 loaded with the material 21 is started and automatically travels along the guideway 27 toward the landing gate of the lifting lift IO.

At this time, if the car 12 is stopped at the landing entrance on the first floor and is waiting, the woot 18Fl is at the gate drive device 19F.
1 - 1 - held open.

Therefore, the automatic guided vehicle 16 gets into the car 12 while being guided by the guide path 27 and the guide path 29.

When the automatic guided vehicle 16 finishes entering the car 12 and stops, the load detector 20 is activated and its detection signal is sent to the control device 17.

Further, information read by the barcode reader 22 when the automatic guided vehicle 16 is boarded is sent to the control device 17. Further, a lifting start command due to the stoppage of the automatic guided vehicle 16 is sent from the transmitter/receiver 31 of the automatic guided vehicle 16 .

After this transmission signal is received by the transmitter/receiver 23 on the side of the basket 12 and taken into the control device 17, the gate drive device 1
9F1 closes the gate 18F1, and the drive motor 15 is started to drive the car 12 to the destination floor designated by the barcode slip 21b.

Here, if the designated floor of the barcode slip 21b is the nth floor nF, after the car 12 stops at the nth floor, the gate 18Fn of the landing is opened by the gate drive device 19Fn.

Furthermore, when the landing gate 18Fn opens, a start command is sent from the transmitter/receiver 23 on the car 12 side to the automatic guided vehicle 16.

When this sending command signal is received by the transmitter/receiver 31 of the automatic guided vehicle 16 and the received signal is taken into the control circuit 16a, the automatic guided vehicle 16 is started and the guide path 2 inside the car 12 is
9 from the car 12 toward the nth floor nF.

When the automatic guided vehicle 16 descends to the designated nth floor nF, the automatic guided vehicle 16 is guided along the guide path 28n laid on the floor nF, and is directed toward the loading cart 35 placed in the stockyard. Drive automatically.

Then, when it reaches the loading truck 35 on the stockyard,
The automatic guided vehicle 16 stops, and the transfer device 26 starts operating. When the transfer device 26 operates, the material 21 on the transfer device 26 is transferred onto the receiving cart 35.

The unloaded automatic guided vehicle 16 moves along the guideway 28n to the entrance on the nth floor, and then gets into the car 12 via the guideway 29.

When it is confirmed that the automatic guided vehicle 16 has boarded the car, the car 12 is driven downward toward the first floor.

As a result, when the car 12 stops and lands on the first floor, the gate 18Fl on the first floor opens, and the empty automatic guided vehicle 16 is taken out onto the first floor along the guideway 29,26. after that,
The vehicle travels to the standby position P and waits for the next loading operation from the forklift 34.

Thereafter, by repeating the same operations, the materials 21 carried into the stockyard 32 on the ground floor can be automatically and unmanned transported to the destination designated by the barcode slip 21b.

In this embodiment, various materials 21 brought into a construction site can be automatically and unmanned transported to a designated work area and work position.

Accordingly, the work of transporting the materials 21 can be carried out at night and outside working hours, including holidays, and there is no need to compete for work vehicles and lifts as in the past.

Furthermore, the number of personnel engaged in transportation work can be eliminated or significantly reduced, and the workers contracted for the construction zone can be fully invested in the work in the construction zone, making it possible to proceed with the work process according to the schedule without delay.

In addition, by having the material supplier attach a barcode label for identification to each pallet at the stage of receiving an order for materials 21 based on the process chart, it becomes unnecessary to attach a barcode label at the delivery stage.
In addition, there is no need for a materials manager, and the transportation work can be carried out even more smoothly and efficiently.

Furthermore, since one unmanned guided vehicle 16 is used to transport and distribute materials to each construction zone, there is no congestion caused by the lifting lift lO and the unmanned guided vehicle 16, and materials can be transported without waste. It becomes possible.

Furthermore, since the material is temporarily placed on the receiving cart 35 placed at the cargo storage area, when it is desired to move the material to the construction position, the material can be transported to the construction position by moving the receiving cart 35. becomes easier.

Further, by installing the transfer device 26 on the automatic guided vehicle 16, it becomes easy to transfer materials to the receiving truck 35 and to carry materials from the forklift 34 to the automatic guided vehicle 16.

In addition, in the present invention, when carrying in materials is automatically transported to a storage location on a designated floor by an automatic guided vehicle, the operation timing of the automatic guided vehicle and the corresponding forklift and lifting lift is as described above. The system is not limited to the one described in the example, and a system in which the entire system is managed and controlled using a main computer may be used.

(Effects of the Invention) As explained above, according to the present invention, with a small number of transport machines using one automatic guided vehicle and one lifting lift,
Materials for construction work can be automatically and unmanned transported to designated construction areas and storage locations. This makes it possible to perform transportation work outside of working hours, significantly reducing the number of personnel engaged in transportation work, reducing transportation costs, and expediting the work process.
