Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bulk cargo consolidation system, particularly when a certain number of individual bulk cargoes are extracted from multiple types of pallet cargoes and mixed onto another pallet. The present invention relates to an effective bulk cargo consolidation system.

[Conventional technology]

In conventional cargo handling systems of this type, multiple types of pallet cargo are stored in the yard, and although the loading and unloading of these pallet cargoes is automated, only a certain amount of bulk cargo is collected from each type of pallet. In the case of extracting the waste and placing it on another pallet, the following three methods were used, for example.

The first method in conventional bulk cargo consolidation processing.

Those who handle this type of bulk cargo consolidation are
As shown in the figure, storage area 2 -1 stores the pallet _1a for bulk processing of baggage A, storage area 2 -1 stores the full pallet 1 of baggage A,
Storage area 4 where full pallet 3 of baggage B is stored
Pallet 3b for bulk processing of cargo B
At least one storage area _6-1 is provided to store pallets _5c for bulk processing of baggage C. , and an empty pallet storage area 8 for storing empty pallets near these storage areas 2, 4, and 6.
The pallets 1a, 3b, and 5c are used to process bulk items in each of the storage areas _2-1 , _4-1 , and _6-1 .
The reason why the full pallets 1, 3, and 5 and the pallets 1a, 3b, and 5c for bulk processing are placed in the same area is to facilitate the transshipment work by operators operating forklifts. .

Such bulk cargo consolidation processing is performed as follows. In this case, for example, baggage A,
It is assumed that bulk cargo is mixed in the order of B and C.

(a) First, an empty pallet is loaded from the empty pallet storage area 8 onto a forklift operated by an operator, and this empty pallet is moved by the forklift to the storage area 2 where cargo A is stored.

(b) Upon arrival at the storage area 2, the bulk cargo A' is manually transferred from the pallet 1a for bulk processing onto an empty pallet. At this time, if necessary, place the empty pallet on the shipping yard floor near the storage area _2-1 of the bulk material pallet 1a, and then use the forklift operated by the operator to move the bulk material pallet 1a onto the empty pallet. Place it on the floor of a nearby shipping yard,
After preparing in this way, the transshipment work is carried out, and when the transshipment is completed, the pallet 1a for bulk processing is returned to its original position by the forklift.

(c) Next, the forklift carrying the pallet loaded with bulk cargo A' is operated and moved to storage area 4 where the next cargo B is stored.

(d) When reaching the storage area 4, manually remove the bulk cargo from the pallet 3b for bulk processing.
Bulk cargo B' is transferred onto the pallet loaded with A'. At this time, if necessary, bulk cargo B' may be transshipped on the shipping yard floor as described in (b) above.

(e) Furthermore, the forklift carrying the pallet loaded with bulk cargoes A' and B' is operated to move it to the storage area 6 where the next cargo C is to be stored.

(f) When the storage area 6 is reached, the bulk items A',
Bulk cargo C' is transferred onto the pallet loaded with B'. At this time, if necessary, bulk cargo C' may be transshipped on the shipping yard floor as described in (b) above.

(g) The pallets thus mixed and loaded are carried outside by a forklift.

(h) When the bulk processing pallets 1a, 3b, 5c are empty, the empty pallets are transported to the empty pallet storage area 8 by hand or by a forklift operated by an operator.

(i) Repeat (a) to (f) above.

The second method in conventional bulk cargo consolidation processing.

Those who perform this type of bulk cargo consolidation processing are
As shown in Figure 8, there is a storage area 2 where a full pallet 1 containing cargo A is stored, a storage area 4 where a full pallet 3 containing cargo B is stored, and a storage area 4 where a full pallet 3 containing cargo B is stored. A storage area 6 in which full pallets 5 are stored is provided, and an empty pallet storage area 8 is provided near these storage areas 2, 4, and 6. A pallet storage area 10 for bulk cargo processing is provided, in which a pallet 3b for processing bulk cargo C and a pallet 5c for processing bulk cargo C are placed exclusively. The pallets 1a, 3b, and 5c are used to process bulk cargo.

Such bulk cargo consolidation processing is performed as follows. In this case, for example, baggage A,
It is assumed that bulk cargo is mixed in the order of B and C.

(a) Empty pallets are first loaded from empty pallet storage area 8 onto a forklift operated by an operator, and pallets 1a, 3b,
5c is moved to a dedicated storage area 10 where only 5c is stored, and mixed on an empty pallet by hand.

(b) When the pallets 1a, 3b, 5c for bulk processing in the dedicated storage area 10 are empty, the empty pallets are transported to the empty pallet storage area 8 by hand or by a forklift operated by an operator, The empty palette and the same full palettes 1, 3,
5 is transported to a pallet storage area 10 for bulk processing.

(c) When the above processing is completed for one type of pallet cargo A', the operator operates the pallet at the transfer destination close to another type of bulk cargo processing pallet 3b in the bulk processing pallet storage area 10. Place it on the claw of a forklift and repeat steps (a) to (c) above.

By doing this, bulk goods A', B', and C' are mixedly loaded on a pallet and shipped.

A third method in conventional bulk cargo consolidation processing (Japanese Patent Application Laid-Open No. 61-33426, etc.).

A loading planning device that creates the loading arrangement and loading order of bulk cargo and the operation sequence of the loading device according to the dimensions of the bulk cargo, and a loading planning device that receives data from the loading planning device and controls each device. a control device to
A marshalling device that receives the bulk cargo in an arbitrary order and sends out the bulk cargo according to the loading order from the control device, and a supply device that supplies the bulk cargo from the marshalling device to a location on a pallet. and a stacking device for stacking the bulk cargo supplied by the supply device onto the pallet, and the bulk cargo is stacked on the pallet by these.

Such consolidation of bulk cargo is carried out as follows.

The stowage arrangement, stowage order, and operation sequence of the stowage device are created by the stowage planning device according to the dimensions of the bulk cargo. A control device receives data from the stowage planning device, and controls each device based on this data. The marshalling device receives the bulk cargo in an arbitrary order and sends out the bulk cargo according to the loading order from the control device. The bulk material from the marshalling device is fed to a pallet location by a feeding device. The bulk goods supplied by this supply device are stacked onto the pallets by a stacking device.

[Problem to be solved by the invention]

However, the above-mentioned method for handling the consolidation of bulk cargo requires complicated manual work for transshipment, and requires a long forklift operated by an operator to transfer one cargo to the next. There was a problem in that it had to be moved a long distance. Moreover, the storage area is small and the
As shown in the figure, for example, the direction of loading and unloading is indicated by arrow a.
If the full pallet 1 of cargo A is stacked from the bottom and the bulk material processing pallet 1a is stacked on top of it, the position of the full pallet 1', that is, the bulk material processing direction. There is a problem in that when a full pallet is carried in and stored under or in the back of the processing pallet 1a, or when a full pallet 1' is taken out, it is not easy to do so because the bulk material processing pallet 1a becomes an obstacle. It was hot.

On the other hand, the above-mentioned method for the mixed processing of bulk cargo solves the problem that the pallets for bulk processing become an obstacle when taking out full pallets. If the pallets are placed flat on top, there is a problem that a forklift must be moved a long distance within the bulk pallet storage area, and if the pallets are stored three-dimensionally outside on shelves. The problem is that pallets for bulk cargo processing must be temporarily placed on a nearby floor using a forklift to facilitate transshipment work.
It still remains.

Furthermore, in the above-mentioned method for the mixed loading of bulk cargo, the bulk cargo is generally stored in bulk cases before being loaded onto the supply device. At this time, (a) the marshalling device has a problem in that the cargo is usually stored in bulk, resulting in low storage efficiency. (b) Also,
The problem is that in order to achieve the final function of transshipment, it is necessary to use a combination of depalletizers and palletizers. (c) Furthermore, when a plurality of depalletizers and a plurality of palletizers are required, there is a problem in that it is necessary to provide a large buffer to operate each of them effectively.

The present invention has been made in order to solve the problems of the prior art described above, and is a method of combining bulk goods that automatically extracts a certain number of individual bulk goods from multiple types of pallet goods and consolidates them onto another pallet. The purpose is to provide a system.

[Means to solve the problem]

A bulk cargo consolidation system according to the present invention that achieves the above object includes a bulk cargo processing pallet storage area in which a plurality of bulk cargo processing pallets each loaded with different types of bulk cargo, and a bulk cargo processing pallet storage area. A bulk cargo transfer device installed near the area and having means for controlling the transshipment work of each of the bulk cargoes, and a bulk cargo transfer device located between the bulk cargo transfer device and the storage area, The present invention is characterized by comprising a conveying means for reciprocating the pallets, and a control means for controlling the conveyance of the pallets for bulk processing by the conveying means based on a predetermined bulk cargo transfer operation procedure.

[Effect]

In the present invention configured as described above, the transport means is controlled by the control means, and the bulk cargo transshipment device installed near the bulk cargo processing pallet storage area adjusts the order of the bulk cargo to be transshipped. Therefore, the pallets for bulk processing stored in the pallet storage area for bulk processing are transported to the bulk cargo transfer device. That is, the conveyance means carries the bulk cargo processing pallet of the bulk cargo to be first transshipped by the bulk cargo transfer device into the bulk cargo transfer device in accordance with the command from the control means. The bulk cargo transfer device is controlled by a means for controlling the bulk cargo transfer operation, and extracts a predetermined number of bulk cargoes from the carried-in bulk cargo processing pallet and loads them onto the mixed pallet. exchange.

When the bulk cargo transshipment device finishes transshipping the bulk cargo, the conveying means returns the bulk cargo processing pallet for which the transshipment has been completed to the bulk cargo processing pallet storage area, and then transships the bulk cargo processing pallet according to the command from the control means. A pallet of bulk cargo to be processed is carried into a bulk cargo transfer device. The bulk cargo transfer device transloads the bulk cargo on the carried-in bulk cargo processing pallet as described above. Thereafter, the above operations are repeated until the predetermined transshipment work is completed.

Therefore, according to the present invention, it is possible to automatically extract a certain number of individual loose items from multiple types of pallet items and consolidate them onto another pallet, thereby saving labor and reducing the burden on the operator. Efficiency can be improved. Moreover, since the bulk cargo is stored on a pallet for bulk processing, the storage space can be reduced and the cost for processing the bulk cargo can be reduced.

The operation of the implementation configured in this way will be explained.

FIG. 5 is a flowchart shown to explain the embodiment.

The control means 80 controls the operations of the conveyance means 70 and the bulk cargo transfer means 60. Control means 80
A predetermined procedure is stored in the .

First, the control means 80 initializes each device (step S10). At this time, the control means 8
0 is set in the reference register N of the CPU 81 as the first number (a) in the table shown in FIG.

The control means 80 is under the control of a CPU 81 that operates according to procedures stored in a main memory 82.
In order to transport the empty pallet 45 to the predetermined position of the bulk cargo transfer means 60, a command to move it to the third storage area 40 is first issued to the guidance radio equipment ground station 72 (step S11). As a result, a predetermined control signal is output from the guidance radio equipment ground station 72 to the guidance line 71. A forklift automatic control panel 75 receives this control command via the guidance radio device onboard station 74.
5 drives predetermined control devices 756 and 757 to move the unmanned forklift 75 along the guide line 71 (step S12). Next, the control means 80
The system determines the position of the unmanned forklift 75 based on the signal sent from the guidance radio equipment onboard station 74 to the guidance radio equipment ground station 72 via the guidance line 71, and commands the third storage area 40. When it is determined that the position has been reached (step S13), a command is issued to place the empty pallet 45 from the third storage area 40 onto the fork 751 of the unmanned forklift 75 (step S14). As a result, each control device 75 is controlled by the forklift automatic control panel 755 according to the command received via the guidance radio device onboard station 74.
8,759 is driven and controlled to place the empty pallet 45 on the fork 751 (steps S15 and S16). Next, a command for transporting the empty pallet 45 by the unmanned forklift 75 to a predetermined position of the bulk cargo transfer means 60 is issued from the control means 80 to the guidance radio equipment ground station 72, the guidance line 71, and the guidance radio equipment on-vehicle station 74.
to the forklift automatic control panel 755 (step S17). As a result, the unmanned forklift 75 moves the empty pallet 45 to the fork 7.
51 and move along the guide line 71 (step S18). Then, the control means 80 determines the position of the unmanned forklift 75 based on the signal sent from the guidance radio equipment onboard station 74 to the guidance radio equipment ground station 72 via the guidance line 71, and if the position is , issues a command to stop the unmanned forklift 75, and issues a set command (step
S19, S20). As a result, unmanned forklift 7
Step 5 operates the mast 752 and fork 751 to set the empty pallet 45 on the bulk cargo transfer means 60 (steps S21 and S22).

Next, the control means 80 refers to the reference register N of the CPU 81, searches for (a) of the table 822 at the address commanded to the reference register N, and searches for the second address specified in (a) of the table 822. storage area 3
A command to move the unmanned forklift 75 to position 0 is sent to the guidance radio equipment ground station 72 and guidance line 7.
1. Provide the guidance radio device to the forklift automatic control panel 755 via the onboard station 74 (step S23).
As a result, the unmanned forklift 75 moves to the designated position in the second storage area 30 (step S24). Then, the control means 80 determines the position of the unmanned forklift 75 based on the signal sent from the guidance radio equipment onboard station 74 to the guidance radio equipment ground station 72 via the guidance line 71 (step 1).
S25), if the location is unmanned forklift 7
At the same time, a command is issued to stop the bulk cargo processing pallet 21a on the fork 751 of the unmanned forklift 75 (step S26).
As a result, the unmanned forklift 75 moves the bulk cargo processing pallet 21a to the unmanned forklift 75.
Place it on the fork 751 (step S27,
S28). Further, the control means 80 issues a command to the unmanned forklift 75 to transport the bulk cargo processing pallet 21a from the second storage area 30 and set it on the bulk cargo transfer means 60 (step S29). . As a result, unmanned forklift 75
Then, the pallet 21a for bulk processing is taken out from the second storage area 30 and transported (step S30). Then, the control means 80 determines the position of the unmanned forklift 75 based on the signal sent from the guidance radio equipment onboard station 74 to the guidance radio equipment ground station 72 via the guidance line 71 (step 1).
S31), if the contact position is unmanned forklift 7
At the same time, a command is issued to stop the bulk cargo processing pallet 21a in the bulk cargo transfer means 60 (step S32). As a result, the unmanned forklift 75 stops at the commanded position and sets the bulk cargo processing pallet 21a on the bulk cargo transfer means 60 (step S33).

When the setting of the bulk material processing pallet 21a on the bulk material transfer means 60 is completed in this manner, the control means 80 issues a bulk material transshipment command to the bulk material transshipment means 60 (step S34). As a result, the bulk cargo transfer means 60 is controlled by the control means 80 from the table 822.
Bulk cargo A' is stacked according to the quantity and stacking pattern instructed based on the data in (c) and (d) (step S35). Based on the signal from the bulk cargo transshipment means 60, the control means 80 determines whether the data in (c) and (d) of the table 822 has been reached, and if the data has not been reached, the process returns to step S35 and further transshipment is performed. is executed, but when it is reached, it moves to the next step (step S36). In the next step, it is determined whether there is any remaining bulk material A' on the bulk material processing pallet 21a (step S37), and if there is any remaining bulk material A', the control means 80
then issues a command to the unmanned forklift 75 to move the bulk cargo processing pallet 21a to its original location in the second storage area 30 (step S38). As a result, the unmanned forklift 7 of the transport means 70
Step 5 moves this pallet for bulk processing to its original location in the second storage area 30 (step S39). Then, the control means 80 controls the guided radio device on-vehicle station 74.
from the guidance radio equipment ground station 7 via the guidance line 71
The position of the unmanned forklift 75 is determined based on the signal sent to the second stage (step S40). A command is issued to return it to the storage area 30 (step S41). As a result, unmanned forklift 75
Then, the bulk processing pallet 21a is returned to the second storage area 30 (step S42). Furthermore, the control means 80 determines whether or not the entire amount of production shown in (e) of the table 822 has been completed (step S43), and if the next bulk cargo B' is to be loaded, the process moves to step S44, and the CPU
81 reference register N is incremented (N=N
+1). Next, in step S45, table 8
The CPU 81 of the control means 80 determines whether the data in (a) and (b) of 22 have completed one cycle, that is, whether the predetermined amount of bulk loading for one pallet has been completed. At step S45, if the process has not finished, the process returns to step S23 without doing anything, but if it has finished, the process proceeds to step S46. Here, since it has not finished yet, step S23
Proceed to.

At this point, the process moves to step S23, and by performing the processes from step S23 to step S45 in the same manner as described above, another pallet 2 for bulk processing is transferred from the control means 80 to the unmanned forklift 75 of the conveyance means 70.
3b is taken out and a command is issued to set it on the bulk cargo transfer means 60. As a result, the unmanned forklift 75 of the conveying means 70 can move the pallet 23 for bulk processing from the second storage area 30 to another pallet 23 for bulk processing.
b is taken out and set in the bulk cargo transfer means 60. When the setting is completed in this manner, the control means 80 issues a bulk cargo transshipment command to the bulk cargo transshipment means 60. As a result, the bulk cargo transfer means 60 executes a process of transferring the bulk cargo B' on the bulk cargo processing pallet 23b to the set empty pallet 45. When the predetermined bulk cargo B' has been transshipped, the control means 80 instructs the unmanned forklift 75 of the transport means 70 to move the bulk cargo processing pallet 23b to its original location in the second storage area 30. issue. As a result, the conveying means 70
The unmanned forklift 75 moves this bulk processing pallet 23b to its original location in the second storage area 30.

Then, the above steps S23 to S51 are repeated until the data in (a) and (b) of the table 822 go through one cycle, that is, until the predetermined transshipment is completed.

Then, when the control means 80 determines that the predetermined transshipment has been completed (step S45), the step
Proceeding to S46, the pallet containing the bulk cargo is transported from the bulk cargo transfer means 60 to the mixed pallet storage area 50 by the unmanned forklift 75 of the transport means 70. Then, the process moves to step S47. In step S47, the first address of table (a) in FIG. 4 is set in the reference register N of the CPU 81, and the process returns to step S11.

If there is no remaining pallet in step S37, the unmanned forklift 75 is used to transport the empty pallet to the third storage area 40 (step S50), and then transports the full pallet 21 from the first storage area 20 to the second storage area. Carry it to area 30 (step S51). Next, it is decided to proceed to step S42.

On the other hand, in step S43, if the entire quantity of the mixed pallet 55 has been completed based on the data (e) of the table 822, the process moves to step S49, where the reference register N of the CPU 81 is cleared and the process is ended.

By repeating this process, it is possible to automatically extract a certain number of individual loose items from multiple types of pallet items and load them onto another pallet, saving labor and reducing the burden on the operator. Work efficiency can be improved. Furthermore, in this embodiment, the bulk cargo is stored on pallets for bulk processing, so the storage space can be reduced, and since no depalletizer or palletizer is used, the cost of processing the bulk cargo can be reduced. It is possible to reduce the

FIG. 6 is a diagram showing another example of the structure of the bulk cargo transfer means.

The bulk cargo transfer means 60', as shown in FIG.
Robotic depalletizer 6 having a predetermined position 62
6 and a robot palletizer 67 having a predetermined position 61 may be arranged side by side via a conveyor, relay stand 68, etc.

Still other embodiments are not shown but will be described. That is, in this embodiment, the transport means 70 is a manned forklift, and the commands from the control means 80 are displayed near the driver's cab or the pallet storage area for bulk material processing (second storage area 30). The operator sees this display and operates the forklift in accordance with the instructions.

Even in such an embodiment, the same effects as in the above embodiment can be achieved.

Furthermore, to explain another embodiment, in the first and second embodiments described above, the bulk cargo transfer means 60, 60' are constructed by machines, but the bulk cargo transfer command issued from the control means 80 is not limited to this. It is also possible to display the procedure for the transshipment work that starts at the bulk cargo transshipment location, so that transshipment can be done manually. At this time, the conveyance means may be an unmanned forklift as in the first embodiment, or may be a manned forklift as in the other embodiments described above.

Similar effects can be achieved with this embodiment as well.

Furthermore, in the above embodiment, the unmanned forklift 75 has been described as operating under the control of the CPU 81 of the control means 80, but the control means 80 initially gives all data to the unmanned forklift 75, and from then on, It may also be a distributed system in which unmanned forklifts 75 operate independently.

In addition, in the above embodiment, the explanation is given to the unmanned forklift 75, but the present invention is of course not limited to this, and the combination of an unmanned guided vehicle and a guide line, or a combination of a stacker crane or an overhead crane and a track rail, Furthermore, it goes without saying that a conveyor or the like may also be used.

It goes without saying that the control means 80 can change the stacking pattern as much as desired as long as the type and number of bulk cargo are satisfied.

According to this embodiment, a certain number of individual bulk items can be automatically extracted from a plurality of types of pallet items and mixed on another pallet, thereby making it possible to save labor.

〔Effect of the invention〕

As described above, according to the present invention, the transport means is controlled by the control means, and the bulk cargo is stored in the bulk cargo processing pallet storage area according to the transshipment work procedure of the bulk cargo to be transshipped by the bulk cargo transfer device. At the same time, the bulk cargo handling pallet is transported to the bulk cargo transfer device, and the bulk cargo transfer device is controlled by the means for controlling the bulk cargo transfer operation, and the bulk cargo processing pallet that has been transported is By transferring bulk cargo to pallets for consolidated pallets,
A certain number of individual bulk items can be automatically extracted from multiple types of pallet items and mixed on another pallet, resulting in labor savings.
