Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a warehousing method in an automated warehouse, and particularly to a warehousing method that is fully integrated with a pallet system and a slipsheet system.

Conventionally, various types of sashes have been used for cargo handling and storage. / is widely used. In other words, by adopting this method in the Nosolet, it is possible to streamline cargo handling work by saving labor, standardizing it, and speeding it up.

However, no cretization with, no! There is a problem in that a large amount of expense is required for purchasing, collecting, managing, repairing, etc.・There are few problems when recycling and using within the same business site, but when carrying out the pallet with the ・Gret, it becomes difficult to manage the collection of the pallet, and sometimes the pallet is left behind or lost outside the facility. , damage may occur. Therefore, the biggest problem is how to collect pallets and increase the turnover rate.

Further, there are problems such as a decrease in loading efficiency due to the weight and volume of the pallet, and an increase in return shipping costs.Furthermore, repairing and replenishing damaged pallets also requires considerable expense.

On the other hand, due to the depletion of natural resources and the rise in prices of wood and wood, in particular, sheets and sheets (slip sheets) have been developed in recent years, and the so-called slip sheet system has been adopted. It became so. Slipsheets are (a) low in unit price, (b) thin and lightweight, so they have good loading efficiency, (...
The slip sheet system has the following characteristics: (2) it requires very little space for storage, (d) it is easy to return and collect, and (e) it is clean and hygienic. It is thought that it will become more widely adopted in the future.

In addition, efficient use of warehouse space for cargo storage,
Recently, multi-level automatic warehouses have been adopted due to the demand for labor saving and automation of cargo handling work. Automated warehouses generally store cargo loaded on conventional grids via a conveyor and stacker crane into predetermined cells of high-rise racks. In automated warehouses,
Normally, the pallet itself serves as a transport board for a conveyor, and in racks, pallets serve as shelves.

Therefore, in the unit load used in place of the above-mentioned Surisono Sheet'kno or Let, the Surisono Sheet is flexible and cannot support the cargo on top of the frame, so it cannot be directly applied to an automated warehouse system. It's impossible. When applying a cargo handling system using only Surisono sheets to a conventional automated warehouse for Zoret, the following equipment modifications are required.

(a) Modification of the noguretizer Add a sheet feeding device.

(b) Modification of the conveyor In the case of a roller conveyor, the gap between the rollers should be made smaller, or the conveyor should be changed to a belt conveyor, 7-of-rate chain conveyor, etc. Conventional slide chain conveyors cannot be used.

(...) Attach all shelves to each cell of the rank.

(d) Stacker crane (7) Modified so that it can swing so that cargo can be taken out from the shelves on both sides.
And install all horn seagull devices.

Such modifications are costly and impractical. Therefore, does the present invention require such a large-scale modification? The purpose of this invention is to combine a slip-on stem, which has a number of advantages, with a conventional automated warehouse system for Lesotho.

In other words, in the present invention, by taking advantage of the advantages of both the goulette and the Surisono sheet, palletizing, conveyance,
Storage and unloading are carried out using conventional pallets, and the shipping department transfers all cargo from pallets to slip sheets, making it possible to ship cargo using slip sheets.

By adopting this method, pallets can be used cyclically within the same office, and shipping outside can be done without using slip sheets, making it possible to take advantage of the features of both pallets and slip sheets. , the above problems can be solved.

That is, the present invention provides a three-dimensional automated warehouse in which a unit load loaded on a cargo container is stored in a predetermined cell of a rack, in which the unit load is transported to a transfer device by a stacker crane and an unloading conveyor, and This relates to an unloading method characterized in that cargo on a unit load or let is transferred onto a slip sheet placed on a slip sheet table.

Furthermore, the present invention uses a stacker crane of an automated warehouse, a transfer device provided at the end of an unloading system consisting of a conveyor, a slip sheet table adjacent to the transfer device, and a slip sheet supply device. This relates to the characteristic shipping method.

The present invention will be explained in more detail below with reference to illustrated embodiments.

First, in an automated warehouse, when a command is issued for two deliveries of a desired cargo, the palletized cargo stored in a predetermined cell of a rank is moved to a stanker crane (not shown).
The pallets 2 and the cargo 3 are then taken out onto the carry-out conveyor 1, and the pallets 2 and the cargo 3 are conveyed as they are onto the transfer table 5 of the size transfer device 4. Existing equipment is used for the above-mentioned ranks, stacker crane, unloading conveyor 1, etc.

The illustrated conveyor 1 (7) is an example of a chain conveyor for pellets, but the present invention is not limited to this.

The transshipment device 4 includes a transshipment table 5 and a pressure grate 6.
And from the zolet rack part 7. The transfer table 5 is a pedestal for receiving all the cargo 3 and the grate 2 conveyed by the conveyor 1, and on its upper surface, for example, a free roller conveyor is provided so that the grate 2 can slide. The pressure plate 6 leaves the unit load plate 2 on the transfer table 5 and inserts only the baggage 3 thereon toward the slip sheet table 8, which will be described later, and is equipped with appropriate guide rails and rollers. This allows it to slide forward and backward (left and right in the figure). A pallet rack section 7 is provided behind the pressure plate 6 (on the right side in the figure) for stacking the lets 2 on the empty plates that have been removed.

As described above, the baggage 3 on the unit load rack 2 placed on the transfer table 5 via the transport conveyor 1 is then transferred onto the slip sheet table 8 by the Glennon year grade 6. (FIG. 2) 1 One slip sheet 10 is supplied in advance to this slip sheet table 8 from a slip sheet supply device 9. The slip sheet supply device 9 feeds the slip sheets one by one to the slip sheet table 8.
Any type of device may be used as long as it can be placed on top of the stacked slip sheets 10a. The sheet is released directly above the . In this case, it goes without saying that the slip sheet 10 may be placed on the slip sheet table 8 manually.

The slip sheet 10 can be of one-tab type, two-tab type, four-tab type, etc., but when the slip sheet 10 is placed on the stand 8, the tab 12 is used so that it can be handled later by the Zino Seagle forklift trunk or other loading equipment. , put it out towards the edge where it touches the loading equipment.

In addition, in order to prevent the slip sheet 10 from slipping on the table 8 when sliding the luggage on the slip sheet 10, the slip sheet table 8 is provided with grits or -13 to make the slip seam 0. suppress. If the slip sheet 10 is a two-tab or four-tab type having tabs on opposite sides, only the tabs may be pressed onto the side edges of the slip sheet base 8.

As shown in Figure 2, using the above-mentioned device, after the cargo 3 is transferred onto the slip sheet 10, it is transferred to a truck, container, or freight car for transportation using a Zonon Yupuru forklift truck or other appropriate equipment. etc., to load luggage along with slip sheets.

By adopting the above method, it is possible to ship using slip sheets without making major modifications to the conventional automated warehouse for turrets, and it is possible to eliminate the shortcomings of the Plet system and to The advantages of the Rizzosheet system can be effectively utilized.
