Description

Description: TECHNICAL FIELD The present invention relates to an unloading and conveying system for elevating and lowering luggage such as building materials and equipment at a construction site, and particularly, depending on whether or not there is a residual load on a floor of a destination. The present invention relates to an unloading / transporting system for a construction site capable of temporarily transferring the above-mentioned luggage to a place other than a predetermined floor and waiting for transfer.

(Prior art) In the conventional construction work of multi-story buildings such as buildings, when raising and lowering luggage such as materials and equipment used for the construction to a predetermined floor, use a lifting lift for unloading and transportation. There are many.

And, in the lifting lift for unloading and transporting as described above,
In order to improve the unloading efficiency and to reduce the number of operators, a system for unmanned unloading and transportation of luggage has been provided in recent years.

(Problems to be solved by the invention) By the way, since the unmanned system described above is merely for automatically unloading a package to a predetermined floor, there is an unloaded package on the floor of the transfer destination and a new package is transferred. If loading is not possible, it is necessary to abandon the unloading of the baggage and stock it on the ground floor until transfer is possible.

However, in general, there are many cases where various materials and equipment are already placed on the ground floor, especially in the field of construction work, and there is a space for stocking luggage that cannot be transferred to a predetermined floor as described above. The current situation is that there are none.

For this reason, a situation arises in which a material carrier, such as a truck, that carries a piece of luggage that cannot be unloaded is waiting near the construction site, which causes problems in terms of efficiently carrying in the luggage and preventing noise around the construction site. There was a problem.

The present invention has been made in view of the above circumstances, and when there is an unloaded cargo on a predetermined floor and it is impossible to unload, carry and transfer a new baggage, the unloading work without giving up the baggage transfer It is therefore an object of the present invention to provide an unloading / transporting system for a construction site, which is capable of continuing the above-mentioned operation and efficiently transporting the parcels carried into the site to a predetermined floor.

(Means for Solving the Problem) In order to achieve the above object, the present invention forms a hoistway over each floor of a building and enables a lift for unloading and conveying loads to be hoisted in the hoistway. In addition to the provision, in the unloading and conveying system for construction site, which is provided with transfer means for transferring the load between the lift and the load carrying-in / carrying-out port of each floor,
Unbalanced load detecting means for detecting whether or not there is an unbalanced load at the baggage loading / unloading port on each floor, and the unbalanced load detecting means has no unloaded load at the baggage loading / unloading port on the floor to which the package is transported. When this is detected, the lift and transfer means are controlled so as to unload, transfer and transfer the load to and from the load loading / unloading port on the floor of the transfer destination, while the remaining load detecting means transfers the load. When it is detected that there is a residual load at the luggage loading / unloading port on the preceding floor, the floor other than the transportation destination, and the floor at which the residual load detecting means has detected that there is no residual load at the luggage loading / unloading port. When the parcel is temporarily moved to the cargo loading / unloading port on the floor, transported, and transferred, and the residual load detecting means detects that there is no residual load at the cargo loading / unloading port on the floor of the transport destination. , Temporary unloading, transportation and transportation of transferred goods Other unloading from cargo loading opening of floor luggage loading opening of the transport destination of the floor, is made of a control means for controlling the lift and transfer means to cause the transport and transfer.

Further, according to the present invention, the control means causes the lift to stand by in the hoistway when the residual load detecting means detects that there is a residual load at the cargo loading / unloading port on the floor of the destination of the cargo. When the load detection means detects that there is no remaining load at the loading / unloading port on the floor of the destination, the lift is moved up and down from the standby position to the floor of the destination, and the lift moves from the lift to the destination. The transfer means is controlled so as to transfer the baggage to the baggage loading / unloading port on the floor.

(Operation) With the above-described configuration, the present invention temporarily puts the luggage on another floor and temporarily places the luggage on another floor when a new cargo cannot be unloaded, transported and transferred due to an unloaded cargo on the floor. When there is no leftover cargo, it can be transferred from the temporary storage to the predetermined floor, so even if there is leftover cargo on the predetermined floor, the unloading work can be continued without giving up on new cargo unloading, transportation and transfer. Therefore, it is possible to efficiently carry the parcels carried into the site to a predetermined floor.

Further, according to the present invention, when there is an unloaded cargo on the predetermined floor and it is impossible to unload, transfer and transfer a new baggage, it is possible to wait until the unloaded cargo on the predetermined floor is exhausted. In the case of required luggage, prioritizing this and unloading on the prescribed floor,
It can be transported and transferred, and its convenience can be greatly improved.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram showing a schematic configuration of a building site luggage transport system according to an embodiment of the present invention, and FIGS. 2A to 2F are flow charts of operations in the building site unloading transport system of FIG. FIG. 3 is an explanatory diagram showing a schematic configuration of another embodiment of the present invention.

In FIG. 1, reference numeral 10 is a lift for unloading and conveying, which is provided so as to be able to move up and down in a hoistway 1 formed over each floor of a building. Reference numeral 12 is a first roller conveyor as a means for bidirectionally transferring the load P between the lift 10 and a load carrying-in / carrying-out port of each floor described later.

Further, the lift 10 is provided with a communication device 14 for performing two-way communication such as light waves with a communication device provided at a luggage loading / unloading exit of each floor other than the ground floor, which will be described later. The operations of the lift 10, the first roller conveyor 12, and the communication device 14 are controlled by a first controller 20 as a control means.

On the other hand, 30, 30, ... Are luggage loading / unloading ports on each floor, and the luggage loading / unloading port 30 is provided for each floor with an automatic hand pallet 40 for horizontally transporting the luggage P within the floor. A second roller conveyor 32 is provided for transferring the load P between them and as a means for transferring the load P bidirectionally between the load carrying-in / out port 30 and the lift 10.

In addition, at the luggage loading / unloading port 30 on each floor, the lift
As a means for detecting whether or not there is a residual load on the second roller conveyor 32 and a gate (not shown) that opens and closes in conjunction with the transfer of the load P between the load transfer port 10 and the load / unload port 30. The remaining load detection sensor 34 is provided.

Further, at least at the luggage loading / unloading port 30 on each floor except the ground floor, the communication device 14 provided on the lift 10 is provided.
A communication device 36 is provided for performing two-way communication with.

And the second roller conveyor 3 on each floor except the ground floor
2. The operation of the remaining load detection sensor 34, the communication device 36, the automatic hand pallet 40, and the gate is controlled by the second control devices 50, 50 as control means individually provided for each floor. On the other hand, the operation of the second roller conveyor 32 and the gate provided at the luggage loading / unloading port 30 on the ground floor is controlled by the first controller 20.

An operation panel 22 provided with a plurality of input keys (not shown) is connected to the first control device 20, and a key input from the operation panel 22 allows the lift 10 to be loaded and placed on the loading floor. Is specified and the mode of whether to operate the system automatically or manually is set.

Further, the first control device 20 is provided with a timer means (not shown) for counting time of a predetermined time-out time, and the parcel P cannot be loaded at a predetermined destination and is temporarily placed on another floor. In this case, a temporary storage information memory (not shown) for storing the floor of the temporary storage destination and the floor of the original transfer destination is provided.

Furthermore, when transferring the luggage P between the lift 10 and the luggage loading / unloading port 30, the first control device 20 and the second control device 20 communicate with each other via the communication devices 14 and 36. Then lift
The load P is transferred by controlling the first roller conveyor 12 on the 10th side and the second roller conveyor 32 on the load loading / unloading port 30 side to rotate in conjunction with each other in the same direction.

In the unloading and conveying system for construction sites according to the present embodiment having such a configuration, when the unloading and conveying of the package P is performed, the first
The control of the control device 20 will be described with reference to the flowchart of FIG.

First, in step S101, a mode setting for automatically or manually operating the system is performed using, for example, the input keys on the operation panel 22, and the setting mode is confirmed in step S103.

Here, in the present embodiment, since the description will be given of the operation in the automatic mode, the description in the case where the manual mode is set in the above step S101 is omitted, and the setting of the automatic mode is confirmed in the above step S103 thereafter. I will continue to explain the case.

Next, in step S105, whether the unloading and transporting this time is new, or the load P temporarily placed on a floor other than the predetermined floor is temporarily set.
Step S1
Similar to the case of 01, the input key of the operation panel 22 is used to confirm the setting mode in step S107.

If the temporary transfer mode is confirmed in step S107, the process proceeds to the transfer subroutine described later with reference to FIGS. 2E and 2F, and if the new mode is confirmed, the process proceeds to step S109. .

In step S109, the floor on which the load P to be loaded on the lift 10 is located, that is, the floor for picking up and the floor of a predetermined destination, that is, the floor for loading, are set by the input keys of the operation panel 22.

The setting input in step S109 is performed, for example, by attaching a bar code label including information on the pickup floor and the loading floor to a predetermined position of the parcel P before the cargo P is unloaded and conveyed. The barcode label (not shown) may be set by reading the barcode label (not shown) connected to the first control device 20.

When the setting input of the pickup floor and the pickup floor is completed in this way, it is determined whether or not the lift 10 is in the set pickup floor (step S111), and when it is not in the set pickup floor, Move the lift 10 up and down to the pickup floor (step S1
13) Proceed to the next step S115, and if the lift 10 is located at the set pickup floor, proceed directly to step S115.

When the lift 10 arrives at the set pickup floor, it is determined whether or not the preparation for pickup of the load P on the pickup floor is completed (step S115). ) To the next step S125.

On the other hand, if the result of the determination in step S115 is not completed, the operator is informed of this by an alarm notification means such as a buzzer or a display connected to the first control device 20, and the operator determines the above. It waits for the input of the operation panel 22 to input an instruction to interrupt the work or to wait (step S117).

Then, the input contents of the step S117 are discriminated (step S119), and if the discrimination result is an instruction to suspend the work, the process returns to the initial state of the step S101.

If the result of the determination in step S119 is that the standby is instructed, it is determined whether or not the preparation for the pickup of the load P on the pickup floor is completed as in step S115 (step S121). If completed, the process proceeds to the next step S125.

On the other hand, if the result of the determination in step S121 is incomplete, the timer means provided in the first control device 20 is actuated and the preset timeout time has expired. The above step S121 is repeated at regular time intervals until it is confirmed in step 20 (step S123).

Then, if preparation for picking up goods is completed before the time is over, the process proceeds to the next step S125, and if it is confirmed that the time-out occurs at step S123, the process returns to step S115.

However, in this state (state in which the timer means has timed out because the preparation for pickup is not completed), the above step S1 is performed.
Since the result of the determination as to whether or not the preparation for the collection of the package P on the fifteenth floor is completed is of course incomplete, a further step is performed after the notification by the alarm notification means as described above.
The process proceeds to S117 and shifts to a state of waiting for the input of the operation panel 22 to input an instruction for interrupting work or for waiting.

Here, the operation of determining whether or not the preparation for picking up the load P on the pick-up floor is completed will be briefly described.

First, when the pickup floor is the ground floor, the presence / absence of the load P on the second roller conveyor 32 is detected by the residual load detection sensor 34 on the ground floor, and the result is confirmed by the first control device 20. It is determined by

On the other hand, when the pickup floor is a floor other than the ground floor, the second roller conveyor is detected by the remaining load detection sensor 34 of the pickup floor.
The presence or absence of the luggage P on the 32 is detected, and the result is sent from the communication device 36 to the communication device 14 on the lift 10 side via the second control device 50, and the first control device 20 sends the result. It is determined by checking.

In this way, when the preparation for picking up the load P on the pick-up floor is completed, the second control device 20 is instructed by the first control device 20 or the second control device 20 and the communication devices 14, 36 are used. The gate on the pickup floor is opened by the instruction signal output from the control device 50 (step S125, FIG. 2B below), and lifted from the second roller conveyor 32 on the pickup floor.
Transfer of the load P to the first roller conveyor 12 of 10 (unloading)
Is performed (step S127).

Here, the operation of picking up the load P on the pick-up floor will be briefly described.

First, when the pickup floor is the ground floor, the second roller conveyor 32 on the ground floor and the first roller conveyor on the lift 10 side
An instruction signal is output from the first control device 20 to 12, so that the first and second roller conveyors 12 and 32 are interlocked and rotate in the same direction to lift the load P from the load loading / unloading port 30. Reprinted in 10.

On the other hand, if the pickup floor is a floor other than the ground floor,
The second roller conveyor 32 on the loading floor and the first roller conveyor 12 of the lift 10 are interlocked by an instruction signal output from the second controller 50 via the controller 20 and the communication devices 14 and 36 of FIG. The luggage P is rotated in the same direction, and the luggage P is transferred from the luggage loading / unloading port 30 to the lift 10.

Next, confirmation of the pickup of the luggage P is performed (step S129),
Then close the gate on the pickup floor (step S131) and lift
Elevate 10 to the loading floor (step S133).

When the lift 10 arrives at the loading floor, luggage P on the loading floor
It is determined whether or not the preparation for loading the cargo has been completed (step S1
35) If it is completed, the process proceeds to the next step S145 shown in FIG.

On the other hand, if the determination result in step S135 is incomplete, for example, the same processing as in step S115 is performed, and the operator operates the input keys of the first control device 20 to select floors other than the loading floor. It waits until a temporary placement or standby instruction is input (step S137).

Here, if the load P placed on the lift 10 is to be transported to a predetermined loading floor as soon as possible, a standby instruction may be given, and it is not necessary to hurry and priority is given to the efficiency of loading and transporting the entire load. Should give a temporary placement instruction.

Then, the input contents of the above step S137 are discriminated (step S139), and when the discrimination result indicates the temporary placement of the luggage P, a temporary explanation will be given later with reference to FIG. 2 (D). Move to the storage subroutine.

If the result of the determination in step S139 is that the standby is instructed, it is determined whether or not the preparation for loading the load P on the loading floor is completed (step S141) as in step S135. If completed, the process proceeds to the next step S145.

On the other hand, if the result of the determination in step 141 is incomplete, the timer means provided in the first control device 20 is actuated and the preset time-out time has expired. The above step S141 is repeated at regular time intervals until it is confirmed in step 20 (step S143).

Then, if preparation for loading is completed before the time is over, the process proceeds to the next step S145, and if it is confirmed that the time-out occurs at step S143, the process returns to step S135.

In this way, when the preparation for loading the luggage P on the loading floor is completed, the second control device 20 is instructed by the first control device 20 or the second control device 20 and the communication devices 14 and 36. The gate on the loading floor is opened by the instruction signal output from the control device 50 (step S145, FIG. 2C below), and the first roller conveyor 12 of the lift 10 and the loading / unloading port of the loading floor. The second roller conveyor 32 on the 30 side operates to transfer (load) the cargo P from the lift 10 to the cargo loading / unloading port 30 on the loading floor (step S147).

Next, confirmation of loading of the luggage P is performed (step S149),
Then, when the gate on the pickup floor is closed (step S15)
1) It is determined whether the loading operation is a normal loading operation or a temporary loading operation on a floor other than a predetermined floor (step S15).
3) If it is a normal loading operation, a series of unloading and transporting operations are terminated and the process returns to step S101.

Note that step S155 performed when it is determined in step S153 that the temporary placement operation is performed will be referred to later in the description of the temporary placement subroutine.

Next, a temporary placement subroutine that branches from step S139 when the determination result in step S139 indicates temporary placement of the luggage P will be described with reference to FIG. 2 (D).

When the temporary placement instruction is confirmed in step S139, the temporary placement information memory provided in the first control device 20 is searched (step S161), and the load P is placed on the second roller conveyor 32. It is determined whether there is a floor that is not temporarily placed (step S16
3) If there is a floor on which the luggage P is not temporarily placed, the temporary storage destination for the current temporary storage is determined from among the floors (step S16).
5), step S in the main routine of FIG. 2 (B)
Returning to 133, if there is no floor on which the luggage P is not temporarily placed, the error processing is performed.

Then, after that, each processing from step S133 to step S151 is performed in the same manner as in the case of normal loading,
In S153, it is determined that the current loading operation is the temporary loading operation.

Therefore, in this case, the number of floors of the temporary storage destination determined in step S163 and the number of floors of the original destination of the parcel P are
For example, each time such information is stored and registered, it is stored and registered in the temporary information memory in a pair with a serial number which is sequentially incremented from 0 (step S15).
5), a series of unloading and conveying operations are completed, and the above step S101
Return to

Next, a transfer subroutine that branches from step S107 when the temporary transfer mode is confirmed in step S107 will be described with reference to FIGS. 2 (E) and (F).

When the temporary transfer mode is confirmed in step S107 of FIG. 2 (A), the temporary storage information stored and registered in the temporary storage information memory of the first control device 20 as shown in FIG. 2 (E). Baggage P
The floor number of the temporary storage destination and the floor number of the original transfer destination of the parcel P are read, for example, from the smaller serial number (step S171).

Then, based on the read result, it is determined whether or not the lift 10 is on the floor of the original transfer destination (step S17).
3) If you are not on the floor of the original destination, lift 10 above.
Move up and down to the floor of the original destination (step S175)
The process proceeds to the next step S177, and if the lift 10 is located at the original transfer destination floor, the process directly proceeds to step S177.

When the lift 10 arrives at the floor of the original transportation destination, it is determined whether or not preparations for loading the luggage P on the floor of the original transportation destination are completed (step S177). Then, the process proceeds to next step S179.

On the other hand, if the determination result in step S177 is incomplete, the process returns to step S171, and in this case, the temporary placement information stored and registered together with the serial number next to the previously read temporary placement information is It is read from the temporary information memory, and the processing from step S173 onward is performed.

When it is confirmed in step S177 that the loading P on the floor of the original destination is completed, the lift 10 is moved up and down to the floor of the temporary loading destination of the temporary loading P (step S1.
79), and it is determined whether or not the preparation for picking up the temporary luggage P on the floor of the temporary storage destination is completed (step S181).

When it is confirmed in step S181 that the preparation for picking up the temporary baggage P on the floor of the temporary placement destination is completed, the process directly proceeds to the next step S183, and the preparation for picking up the temporary baggage P is not completed. If this is the case, this step S181 is repeated until the preparations for picking up the temporarily stored luggage P on the floor of the temporary storage destination are completed.

When it is confirmed that the preparation for picking up the temporary luggage P is completed, the same operations as those in steps S125 to S131 are performed as shown in FIGS. 2E and 2F (step S1).
83 to step S189, step S187 and the following FIG. 2 (F), and subsequently the lift 10 is moved up and down to the floor of the original transfer destination (step S191).

Here, it is determined whether or not preparations for picking up the temporary luggage P on the floor of the original transport destination are completed (step S193),
If the preparation for picking up the temporary baggage P is not completed, this step S193 is repeated until the preparation for picking up the temporary baggage P on the floor of the original destination is completed, and the preparation for picking up the bag is completed. If confirmed, the process proceeds to the next step S195.

When it is confirmed that the preparation for picking up the original floor of the destination is completed (step S195), the same operations as those in steps S145 to S151 (steps S197 to S2)
01) is performed, and then the temporary placement information regarding the temporary placement package P for which the temporary placement transfer has been executed is erased from the temporary placement information melody (step S203), and a series of temporary placement transfer operations ends, and the above step S171 is performed. Return to.

In the above embodiment, step S101 of the main routine,
In S105, S109, S113, and S117, various conditions are manually input and set each time, but input is set in advance before starting operation, and fully automatic operation is performed after starting operation. You may do it.

Further, in the above-mentioned embodiment, the control device for controlling the system is composed of the lift 10 side and the luggage loading / unloading port 30 side of each floor, but these may be integrated into one.

Further, in the above embodiment, the first and second roller conveyors 12 and 32 are used as means for transferring the load P between the lift 10 and the load carrying-in / carrying-out port 30 on each floor.
As shown in the figure, a slide fork 16 is provided on the lift 10 side, and the slide fork 16 is controlled by the first control device 20 to transfer the load P between the lift 10 and the load loading / unloading port 30 of each floor. You may make it carry.

In this case, the control by the first and second control devices 20, 50 during the operation of the system shown in FIG. 3 is substantially the same as the contents described in FIGS. 2 (A) to (F).

(Effect of the invention) As described above, according to the present invention, when there is an unloaded cargo on a predetermined floor and a new cargo cannot be unloaded, transported and transferred, the cargo is temporarily placed on another floor. If you leave it and can transfer it to the predetermined floor from the temporary storage when there is no remaining load on the predetermined floor, even if there is an unloaded load on the predetermined floor, you will abandon unloading, transporting and transferring new luggage. It is possible to continue the unloading work without having to do so, and thus it is possible to efficiently carry the cargo carried into the site to a predetermined floor.

Further, according to the present invention, when there is an unloaded cargo on the predetermined floor and it is impossible to unload, convey and transfer a new load, it is possible to wait until the unloaded cargo on the predetermined floor is exhausted. In the case of required luggage, prioritizing this and unloading on the prescribed floor,
It can be transported and transferred, and its convenience can be greatly improved.
