Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a transport device for construction materials and equipment delivered to a construction site, and in particular, it is capable of transporting construction materials and equipment to a construction zone etc. without any personnel. 6. Concerning a device for transporting materials and equipment for construction work (prior art) Construction production has unique characteristics that are different from other industrial production.

For example, there is a single production method in which only one building is originally produced based on one design, and the production is carried out outdoors, and the production system is a method in which multiple subcontractors perform the work simultaneously in different construction areas. are taken.

In addition, because the types and quantities of piping equipment (a general term for materials, machinery, and equipment, etc.) used in construction are extremely large and relatively large in volume, large amounts of pipe equipment brought in are stored in stockyards. When transporting to a work site or a work area, it is generally carried out manually during working hours using a work vehicle such as a forklift and a lift.

(Problems to be Solved by the Invention) In such conventional pipe equipment transportation methods, when pipe equipment brought into the delivery entrance of a construction site is transported separately for each destination in the construction area or stockyard, it is difficult to match the construction plan. A person in charge of pipe equipment management who is familiar with the process chart created according to the process is required.
Furthermore, in order to eliminate errors in the destination of pipe equipment, it is necessary to clearly indicate the destination of the pipe equipment, or to attach a tag with the destination written on it.

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 pipe equipment to the destination, transport vehicles such as fork lifts and lifting lifts are used, but since most of these operations are done manually, the destinations are spread over multiple floors. □ If the destinations for delivery become diverse, the number of workers engaged in transportation will increase, leading to an increase in transportation costs.

Furthermore, in construction production, various types of construction work are carried out simultaneously based on schedules, so a large amount and variety of pipe 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 to each construction zone, reducing the efficiency of transporting pipe equipment and hindering the actual construction work in the construction zones as well as the work schedule. There was also the problem of stagnation.

The present invention has been made in view of the above-mentioned points, and is a construction work material that can automatically transport pipe equipment delivered to a construction site to a predetermined work position using a transport vehicle and a lifting lift. The purpose is to provide equipment for transporting equipment.

(Means for Solving the Problems) The present invention will be explained in conjunction with FIGS. 1 and 2 showing an embodiment. a car 12 for transporting pipe equipment installed in the hoistway so as to be movable up and down; a driving means 13 for driving the car 12 up and down; A code reader 19 that reads the identification code 17b attached to the loaded pipe equipment 17 or its pallet 17a, and a code reader 19 installed in a predetermined pattern on each floor IP-nF between the entrance of the hoistway and the cargo storage area. The taxiways 231 to 23n and each of the taxiways 2

4, and a transmitter 2 that is installed in the car 12 and sends a work permission command to the transport vehicle 20 waiting at the entrance/exit.
1, and a control means 15 that controls the driving means 13 so that the car 12 travels to a designated destination floor based on the identification code read by the corner code reader 19, and also causes the transmitter 21 to oscillate at the destination floor. and an unmanned work vehicle 28 for loading the pipe equipment 17 to be carried into the cage 12 in the carrying-in/out area 26 for construction pipe equipment.

(Function) When the unmanned working vehicle 28 waiting at the entrance of the loading/unloading area 26 receives the command signal from the transmitter 21, the pipe equipment 17 is loaded into the cage 12.

Then, when the code reader 19 inside the car 12 reads the identification code attached to the pipe equipment 17 or its pallet 17a, the control means 15 specifies the destination floor of the car 12, and the car 12 runs toward the destination floor. let

When the car 12 stops at the designated floor, a work permission command is sent from the transmitter 21 to the transport work vehicle 20, which starts the transport work vehicle 20, takes out the rented equipment] 7 from the car 12, and transports it. The identification code is read by the code reader 24 mounted on the work vehicle, and the transport work vehicle 2 is moved according to the code.
0 along the taxiway to the designated storage location.

Therefore, according to the present invention, rental equipment can be automatically transported to a predetermined work position.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2.

Figure 1 is a diagram showing the overall configuration of the material and equipment transport equipment for construction work.
FIG. 2 is a schematic diagram showing the relationship between the lift, unmanned work vehicles on each floor, and the stockyard.

In the figure, a lifting lift designated by the general reference numeral 10 is a temporary hoistway 11 formed over each floor IP-nF of the building.
It has a basket 12 for transporting cargo that is movable up and down inside, and an electric hoist 13 installed at the top of the hoistway 11, and a wire rope 14 wound around a sheave 13a of the electric hoist 13.
A car 12 is connected to one of the hanging ends, and a counterweight 14A is connected to the other hanging end.

A control device (control panel) 15 automatically drives the car 12 to the destination floor in response to the landing call and car call on each floor, and when the car 12 lands on the destination floor and stops, a gate drive device installed in the car 12 is operated. An opening/closing command is sent to 16a or 16b, thereby controlling the opening/closing of the left and right car gates and the corresponding landing gates.

In addition, inside the basket 12, there is an inventory detector 18 that detects the presence or absence of the rental equipment 17, and a barcode tag 17b for identifying the destination attached to the rental equipment 17 or its pallet 17a. Optical signal transmission that sends a command signal for unloading or loading the rental equipment 17 to the barcode reader 19 that detects the loaded position and the transportation vehicle 20 such as a forklift that waits at the entrance of each floor IF=nF. A container 21 is provided.

The car 12 and the control device 15 are connected by a cable 22, and the cable 22 transmits the signals detected by the cargo presence detector 18, the barcode reader 19, the landing signal, etc. to the control device 15, and also sends gate opening/closing commands. Gate drive device 16a.

16b, and the transmission of the optical signal transmitter 21 can be controlled.

As shown in Figure 2, each floor IF-nF of the building has 20 transport work vehicles between the boarding/disembarking area and the storage area (stockyard).
Semi-fixed taxiway for unmanned operation23. ~23
n is installed.

The transportation vehicle 20 carries rental equipment 17 or its pallet 1.
A barcode reader 24 for reading the barcode tag 17b attached to the car 12 and a receiver 25 for receiving the optical signal from the transmitter 21 of the car 12 are installed.

The barcode sheet 17b indicates the destination of the rental equipment 17, and specifies the destination floor for the lifting lift 10, and specifies the cargo storage location for the transport vehicle 20 on each floor. .

In addition, the floor IF on the first floor is provided with a loading/unloading area 26 for the rental equipment 17 with respect to the lifting lift 10, and this loading/unloading area 26 is provided with an optical reception area 26 for loading the rental equipment 17 into the basket 12. An unmanned work vehicle 28 with a container 27 is waiting.

The transport vehicle 20.28 is equipped with an autonomous turning function and a copying cargo handling control (placement directly on the floor, stacking) function.

Next, the operation of this embodiment configured as a "double series" will be explained.

In the pipe equipment transporter area 26 on the 1st floor, when the unmanned work vehicle 28 carrying the rented equipment 17 with its pallets is waiting at the entrance to the lift IO, the car 12 stops at the 1st floor IF, and the car 12 stops at the IF on the 1st floor. When the car gate and the landing gate are opened by the driving device 16a, the optical signal transmitter 21 operates to send out an optical signal for permission to work. This light signal is sent to the unmanned work vehicle 2.
When the receiver 27 of No. 8 receives the signal, the unmanned working vehicle 28 starts work and loads the rental equipment 17 along with the pallet into the basket 12.

When the rental equipment 17 is loaded into the car 12, the inventory detector 18 operates to detect the loading of the rental equipment 17 and sends a detection signal to the control device 15.

Further, the barcode reader 19 scans the barcode slip portion of the rental equipment 17 and transmits the scan signal to the control device 1.
5, it is determined whether the rental equipment 17 has been loaded in the proper position.

Here, when it is determined that the loading position of the rental equipment 17 is not appropriate, the unmanned working vehicle 8 is operated again to correct the loading position of the rental equipment 17.

When the loading position of the rental equipment 17 is determined to be appropriate, the barcode tag 17b is read and the signal is sent to the control device 15.

Then, an evacuation command is issued to the unmanned working vehicle 28 from the optical signal transmitter 21 to evacuate the unmanned working vehicle 28 from inside the cage 12 and to move on to the next loading work 1 of rental equipment.

The control device 15 that has taken in the contents of the barcode slip 17b outputs a gate close command to the gate drive device 16a to close the car and landing gates, and then gives a start command to the hoisting machine 13 to close the car and the landing gate. is caused to travel to the destination floor designated by the barcode slip 17b.

Here, if the designated floor of the barcode slip 17b is the nth floor nF, the car 12 stops at the nth floor, and the gates of the car and the landing are opened by the gate driving device 16a.

Then, the optical signal transmitter 21 sends an optical signal for permission to work to the transportation vehicle 20 waiting at the entrance on the nth floor.

When this optical signal is received by the receiver 25, the transport vehicle 2
0 starts the operation, lifts up the rental equipment 17 in the car 12 along with the pallet 17a, and carries it out of the car 12.

At the same time, the barcode reader 24 reads the barcode tag 2 17b attached to the rental equipment 17 or the pallet 17a to determine the destination of the rental equipment 17.

For example, when it is determined that the loading lane 231 is on the nth floor nF, the transport vehicle 20 is guided along the guide path 23n while traveling toward the loading lane 23n1.

When it reaches the top of the storage lane 23n, the transportation vehicle 20 stops and places the rental equipment 17 on the storage lane 23n1 as shown in FIG.

Furthermore, the transport work vehicle 20 that has completed unloading is placed on the taxiway 23.
While being guided along the n, I moved to the boarding and exit entrance on the nth floor.
Waits for the next loading operation.

Thereafter, by repeating the same operation, the rental equipment 17 carried into the construction rental equipment transporter area will be automatically and unmanned transported to the destination designated by the barcode slip 17b.

The transportation work on each floor other than the 1st floor IF is carried out in the same way as described above, but in the case of the 1st floor IF, the rental equipment 17 loaded in the car 12 is carried out while the car 12 remains stopped. The cargo is unloaded by opening the gate drive device 16a of the car and landing gate opposite to the entry area 26.

In this embodiment as described above, the various rental equipment 17 brought into the construction site can be automatically and unmanned transported to the designated work area and work position.

As a result, transportation of rental equipment 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, at the stage of receiving an order for rental equipment 17 based on the process chart, the rental equipment supplier will place an identification barcode sheet 17b on each pallet.
By attaching a bar code, it is not necessary to attach a barcode tag at the delivery stage, and a rental equipment manager is also not required, so that the transport work can be carried out even more smoothly and efficiently.

A Note that the present invention is not limited to the method shown in the above embodiment.

(Effects of the Invention) As explained below, according to the present invention, materials and equipment 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.
