Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trolley storage system and a pallet for mounting a trolley, and more particularly to a trolley storage system for storing an in-flight meal transport trolley in a facility for preparing in-flight meals of an aircraft. And a truck-mounted pallet for mounting an in-flight edible truck.

[0002]

2. Description of the Related Art Generally, an in-flight meal preparation facility for preparing in-flight meals served by an airplane or the like receives orders for in-flight meals from a plurality of airlines. In-flight meal transport trolleys (hereinafter referred to as carts) that store in-flight meals are available in long and half sizes, and the same long size (or half size) is slightly different depending on the airline. In the food preparation facilities, carts are prepared for each airline.

[0003] The storage of carts in an in-flight meal preparation facility involves:
In general, it is common to place a plane in a flat storage warehouse, and when an in-flight meal is ordered from an airline, the ordering cart for the airline is placed in the flat storage warehouse. I just take it out.

In such an in-flight meal preparation facility, when the number of stored carts increases, the inside of the in-flight meal preparation facility becomes narrow, resulting in poor operation efficiency. In addition, since the carts are manually supplied to the necessary processes, when the number of carts is large or when the supply places are diversified, the operation is extremely labor-intensive.

For this reason, a hanger rail type cart storage system has recently been proposed as an automatic system for loading and unloading carts, and has been adopted mainly in Europe and the United States.

[0006]

However, the hanger rail type cart storage system requires a flat space for suspending the cart hanger for holding the cart, so that the number of carts to be stored increases. A lot of plane space must be secured in advance. Also, the types of carts that can be mounted on the cart hanger are limited, and cannot be applied to all carts. Furthermore, it is necessary to clear laws and regulations such as the Fire Defense Law, which has a legal disadvantage that it is difficult to introduce it in Japan, which has many restrictions.

Various automatic warehouse storage systems for automatically storing general cargo have been proposed. In such an automatic warehouse storage system, it is assumed that the cargo does not move even if it rolls slightly, and a bogie that moves greatly even if it rolls slightly, such as an airline cart with wheels on the bottom. It is difficult to apply the method, and if it is forcibly applied, there is a problem in that the cart may move during the transfer and may protrude from the pallet, fall, or fall on the pallet.

In addition, when an in-flight meal is ordered from an airline, a cart for the ordered airline is taken out of a flat storage warehouse by an amount corresponding to the order. There is no system for continuously loading and unloading carts from the storage warehouse when ordering in-flight meals from the airline or storing unused carts.
There is also a drawback in that carts need to be manually loaded and unloaded continuously.

In view of the above, it is an object of the present invention to provide a trolley storage system and a pallet for mounting a trolley, which can smoothly carry out the loading / unloading operation of the trolley, and in particular, a cart storage warehouse in an in-flight meal preparation facility. In the above, an object of the present invention is to provide a trolley storage system and a pallet for mounting a trolley, which can smoothly carry out a loading / unloading operation of a cart.

FIGS. 5 and 6 show the second conveyor 40b.
As shown in (A), it is the loading area of the cart,
The carts 14 to be stored are manually loaded on the empty pallets 12 sequentially transferred from the first conveyor 40a.
In this embodiment, the height of the conveyor is adjusted so that the cart mounting surface of the pallet 12 on the second conveyor 40b is flush with the floor surface, whereby the cart 14 can be smoothly placed on the pallet. 12 will be mounted.

To the personal computer 42, various information such as the company name of the cart 14 to be stored, the number of carts 14, the type of cart such as long size or short size, and the required number of pallets are input. Based on this information, a warehousing program, which will be described in detail later, is implemented.
The cart 14 is automatically transported to a specific shelf 24a and stored.

Also, on the downstream side of the second conveyor 40b,
A load detector 46 for detecting whether a cart is mounted on the pallet 12 is provided. The load height detector 46 irradiates light such as infrared rays to a predetermined height position, and detects the height of the load on the pallet 12 based on the presence or absence of reflected light or transmitted light, so that the cart is mounted on the pallet. Is detected.

Here, the program stored in the personal computer 42 will be described. In the in-flight trolley automatic storage warehouse 10 of the present embodiment, a storage program is stored in the personal computer 42 provided at the storage station 30 on the first floor, and a storage program is stored in the personal computer 42 provided at the storage station 32. It is remembered.

Here, the warehousing program stored in the personal computer 42 provided in the warehousing station 30 will be described with reference to FIGS. 7 and 8, and the warehousing process in the warehousing station will be described. First,
Pressing a mode switching button (see FIG. 6B) provided on the personal computer 42 puts the personal computer 42 into the storage mode. This starts the storage program. The storage program includes a pallet supply process and a storage process.

FIG. 7 shows a flowchart of the pallet supply process. In step 100 of FIG. 7, it is determined whether various information regarding the cart 14 to be stored is input to the personal computer 42 by the operator. here,
The various information includes the company name of the cart 14 to be stored, the number of carts to be stored, the type of cart such as a long size or a short size, the number of carts 14 placed on a pallet, and the total number of necessary pallets 12.

In the next step 102, it is determined whether the number of carts 14 is a multiple of the number of carts that can be mounted on one pallet. For example, in the present embodiment, the number of carts that can be mounted on one pallet 12 is two in the case of the long cart 14a and three in the case of the short cart 14b. It is determined whether the number is a multiple of 2 for the cart 14a or a multiple of 3 for the short cart 14b. If the determination is affirmative, the process proceeds to step 104.

In step 104, the pallet horizontal transport device 16 and the pallet horizontal transfer device 16 are supplied so that multiple empty pallets (a value obtained by dividing the number of incoming carts 14 by the number of carts that can be loaded on one pallet) are supplied to the receiving station. An instruction is issued to the pallet vertical transfer device 18 and the present routine ends.

If the determination in step 102 is negative, the process proceeds to step 106, where it is determined from the inventory data whether a pallet on which a fraction of trucks can be mounted is in the storage area. If the determination in step 106 is affirmative, the process proceeds to step 108 and issues a delivery instruction for the corresponding pallet to the crane controller. For example, short cart 14
If one b is left, the fraction pallet 12 on which one short cart 14b can be mounted, that is, FIG. 4B or FIG. 4D is preferentially allocated. If there is no corresponding pallet, a fraction pallet 12 in which one or more short carts 14b can be mounted, that is, FIG. 4 (F) is allocated.

Similarly, when two short carts 14b are left, the fraction pallet 12 on which two short carts 14b can be mounted, that is, FIG. 4 (F) is preferentially assigned, and there is no corresponding pallet. In such a case, the fraction pallet 12 in which one short cart 14b can be mounted,
That is, FIG. 4B or FIG. 4D is allocated. Similarly, when a long cart is mounted, a fraction pallet 12 on which one long cart 14a can be mounted, that is, FIG. 4B is allocated.

At this time, a stacking mode is provided, the cart mounting information of the pallets before the stacking is displayed on a display, and the cart mounting information is corrected. In addition, it is preferable to input the arrival flight number for the account of the result.
After that, if the load is checked in the same manner as the above-described warehousing process and the pallet 12 is OK, the pallet 12 is stored in the empty shelf of the storage area from the first warehousing port 34a, and the stock information is updated.

If there is no corresponding pallet, the judgment is negative in step 106, a fractional cart is mounted on an empty pallet, and the fractional pallet is stored in the shelf 24a. Therefore, in step 110, (multiple + 1)
The pallet horizontal transfer device 16 and the pallet vertical transfer device 18 are instructed so that empty pallets (a value obtained by dividing the number of carts 14 to be received by the number of carts that can be loaded on one pallet + 1 minute) are supplied to the receiving station. And exit this routine.

Thus, the pallets required for storing the cart are supplied to the storage station 30. The operator sequentially loads carts on empty pallets and presses a confirmation button of the personal computer 42. Thereby, the stocking process is started.

FIG. 8 shows a flowchart of the warehousing process.
In step 200, it is determined whether or not the storage support is issued by pressing the confirmation button. If the determination in step 200 is affirmative, the process proceeds to step 202, where the load is checked. The height check is a process of irradiating light such as infrared rays to a predetermined height position and detecting reflected light.

In the next step 204, it is determined whether or not the checked pallet is passable based on the detected reflected light. If the pallet is OK, the flow proceeds to step 206 to issue a traffic permission, and then proceeds to step 208. Thereby, the pallet 12 is moved from the second conveyor 40b to the third conveyor 40c.
And stored in the storage area through the first storage port 34a.

If it is determined in step 204 that it is not OK, the process proceeds to step 212, where a warning sound such as a buzzer, a blinking screen, or a blinking light provided with a blinking light is issued. . Preferably, at this time, the second conveyor 40b may be stopped.

In the next step 214, it is determined whether or not the cart has been remounted on the pallet 12. This determination may be made so that the operator inputs the re-installation into the personal computer 42 after re-installation. If it is determined that it has been mounted again, the process returns to step 202 and the above-described processing is repeated. If not, the process returns to step 212, and the above-described processing is repeated.

In step 208, it is determined whether the number of pallets n (where n is a positive integer) is equal to the required number of pallets P first input, and if so, the inventory data is updated. Transition. If not equal, the process proceeds to step 216 to increment n, and then returns to step 202 to repeat the above-described processing.
If the number of pallets P has not been input, it is determined that P = 1 and the inventory data is updated.

In step 210, the received cart is
The inventory data is corrected by adding the position information of the pallet on which the cart is mounted and the shelf on which the pallet is stored to the inventory data as new receipt information. In addition, for example,
It is possible to collectively display in a list such as for each company and each storage date and display it as desired.

In the next step 212, it is determined whether or not there is an input of data of a cart to be mounted next. If there is an input, the flow returns to step 202 and the above-described processing is repeated.
If there is no input, this routine ends. When a plurality of pallets are input, it is preferable to set so that carts of the next type cannot be installed unless carts are installed for the number of pallets input.

Here, the retrieval program stored in the personal computer 42 provided at the retrieval station 32 will be described with reference to FIG. 9, and the retrieval processing at the retrieval station will be described. First, a mode switching button provided on the personal computer 42
(See FIG. 6B) and press the personal computer 4
2 is a delivery mode. As a result, the retrieval program starts.

First, in step 300 of FIG. 9, it is determined whether or not information regarding the cart to be delivered has been input to the personal computer 42 of the delivery station 32 by the operator. The information on the cart to be delivered is, for example, a person in charge, a company, an item, a quantity, and the like, and a plurality of items and quantities can be set at one time. Note that, in the in-flight food cart automatic storage warehouse 10 of the present embodiment, the item is basically a cart, but it is also possible to load a load having the same dimensions as the cart. Describe the type.

In the next step 302, the stock corresponding to the input outgoing data is allocated, and it is determined whether or not the stock is available based on the stored stock data. To be warned, such as issuing a warning sound such as a buzzer, blinking the screen, blinking with a blinking light, etc., and rewriting the data to be released so that all the items are released as much as there is stock. Prompts the user to re-enter the issue data. When the data is input again in step 316, the process returns to step 302, and the above-described processing is repeated. If it is determined in step 302 that there is a stock, the process proceeds to step 304 to determine whether the number of carts requested to be taken out is a multiple of the number of carts that can be mounted on one pallet. For example,
In the present embodiment, the number of carts that can be loaded on one pallet 12 is two in the case of the long cart 14a and three in the case of the short cart 14b. If it is, it is determined whether it is a multiple of 2 and if it is the short cart 14b, it is determined whether it is a multiple of 3. If the determination is affirmative, the process proceeds to step 306.

If the determination in step 304 is affirmative, the flow shifts to step 318, where it is determined from the inventory data whether a pallet having a fraction of trucks is in the storage area. If the determination in step 318 is affirmative, the flow shifts to step 320 to allocate the shelf in which the corresponding pallet is stored, and to output the information of the allocated shelf to the pallet horizontal transport device 16 and the pallet vertical transport device 18 as a delivery instruction. , To step 306.

For example, if the short cart 14b is 1
In the case of a table, the fraction pallet 12 on which one short cart 14b is mounted, that is, FIG. 4 (C) or FIG. 4 (F) is preferentially allocated. If there is no corresponding pallet, a fraction pallet 12 having two short carts 14b mounted thereon, that is, FIG. 4D is allocated.

Similarly, the fraction of the short cart 14b is 2
In the case of a table, the fraction pallet 12 on which two short carts 14b are mounted, that is, FIG. 4D is preferentially allocated. Similarly, when a long cart is mounted, the fraction pallet 12 on which one long cart 14a is mounted, that is, FIG. 4B or FIG. 4C is allocated.

At this time, a take-out mode is provided, the cart mounting information of the pallet 12 before taking out is displayed on a display, and the cart mounting information is corrected. In addition,
It is advisable to input the arrival flight number to record the results. After that, if the load is checked in the same manner as the above-described warehousing process and the pallet 12 is OK, the pallet 12 is stored in the empty shelf of the storage area from the first warehousing port 34a, and the stock information is updated.

In step 306, shelves storing multiple pallets (multiplied by the number of carts 14 to be taken out by the number of carts that can be mounted on one pallet) are allocated, and the equipment state and tracking state are set. The information of the shelves allocated in accordance with the situation is output to the pallet horizontal transport device 16 and the pallet vertical transport device 18 as a delivery instruction, and the process proceeds to step 308.

If the corresponding pallet does not exist, the judgment is negative in step 318, and the pallet 12 full of carts is selected. Therefore, in step 322, (multiple + 1) (the number of carts 14 to be taken out divided by the number of carts that can be mounted on one pallet + 1)
An instruction is issued to the pallet vertical transfer device 18 so that the full pallet of (minute) is supplied to the storage station, and the process proceeds to step 308.

The crane controller takes out the pallet 12 from the allocated shelf 24a based on the shelf information input from the personal computer 42, conveys it to the second outlet 36b, and reports the completion of the exit to the personal computer 42. . Therefore, in step 308, it is determined whether or not there is a report of completion of the delivery from the crane controller. If it is determined that there is a report, the process proceeds to step 310 to correct the inventory data and record the delivery result.
In addition, in order to perform re-entry at times other than all-in-stock, re-entry data is created. The re-entry data is input to the personal computer 42 as various types of information on the cart in the above-described entry processing. In addition, empty pallet 1
2 is a pallet horizontal transfer device 1 from the second storage port 34b.
6 and the pallet vertical transfer device 18.

In the next step 312, it is determined whether or not there is an input of the cart data to be taken out next. If there is an input, the flow returns to step 302 to repeat the above-described processing.
If there is no input, this routine ends.

Preferably, at the time of retrieval at the retrieval station 32, the full pallets are preferentially allocated to the remaining fraction pallets (pallets with one short cart 14b or pallets with two short carts). Good to do.

As a specific example, a case where ten short carts 14b of Company A are delivered from the warehouse will be described below, but the present invention is not limited to these numerical values. In order to release 10 short carts 14b of Company A, first, three full pallets (see FIG. 4E) are allocated and a fraction pallet (FIG. 4C or FIG. 4) on which one short cart 14b is mounted. (See (F)) is preferentially assigned to one unit.

If there is no fraction pallet equipped with one short cart 14b, a fraction pallet equipped with two short carts 14b (see FIG. 4D) is retrieved. When a fraction pallet with two short carts 14b is attracted, one pallet is taken out of the fraction pallet and then returned to the storage area as a fraction pallet with one short cart 14b (see FIG. 4F). .

Further, when there is no fraction pallet, four full pallets are attracted, one short cart 14b is taken out of one of them, and then a fraction pallet having two short carts 14b mounted thereon (FIG. 4D ) Is stored in the storage area 20 again.

If there are not three full pallets, the pallets with the least number of pallets are sequentially allocated and the short carts 14b are allocated to the ten pallets. In addition, the short cart 1 is stored in the in-flight food cart automatic storage warehouse 10.
If no 4b is stored, all the stocks, regardless of the full load or the fraction, are taken out and the shortage number is displayed on the terminal.

Further, the short cart 14b of the company A is set to 1
When one car is to be taken out, three full pallets are assigned and one fraction pallet equipped with two short carts 14b is assigned preferentially.

If there is no fraction pallet equipped with two short carts 14b, two fraction pallets equipped with one short cart 14b are attracted and discharged.
2 fraction pallets with one short cart 14b
If there is no short cart 14b, one fraction pallet with one short cart 14b is attracted, one full pallet is attracted, one short cart 14b is taken out, and a fraction pallet with two short carts 14b is attached. And store it in the storage area again.

Further, when there is no fraction pallet, four full pallets are attracted, two short carts 14b are taken out of one of the pallets, and then a short pallet having one short cart 14b is loaded into the storage area again. Get in stock.

If there are not three full pallets, the short pallets 14b are allocated to the short pallets 14b in order from the pallets with the smallest number of pallets. In addition, the short cart 1 is stored in the in-flight food cart automatic storage warehouse 10.
If 11 units of 4b are not stored, all the stocks are loaded regardless of the full load or the fraction, and the shortage number is displayed on the terminal.
