2. Description of the Related Art As a conventional technique relating to a method for storing and packing articles, there is known one disclosed in JP-A-5-8807.

The conventional technique described in the above publication will be explained. In Japanese Patent Laid-Open No. 5-8807, based on the expected quantity of goods received and the quantity that can be stored in the storage facility (automatic warehouse) at that time, It is calculated whether or not the expected arrival quantity is larger than the warehousing quantity, and if so, it is set that some of the goods to be received will be stored in another storage facility (overflow area), and then the above storage It describes a method of storing goods that starts the storage of all the above-mentioned goods that are received in the equipment and the above-mentioned other storage equipment. The goods are stored in the storage equipment (automatic warehouse) or other storage equipment (overflow area). They are palletized before they are stored, stored in a state of being stacked on pallets, and then depalletized when they are stored, and are handled on a case-by-case basis.

[0004]

However, the above-mentioned conventional techniques have the following problems.

That is, in the article storage method described in JP-A-5-8807, articles stored in another storage facility (overflow area) are stored in the storage facility (automatic warehouse).
It is configured so that the goods are sorted and shipped after being re-stocked in the warehouse, which complicates the storage and sorting route for goods, and requires high storage and retrieval capacity for storage equipment (automatic warehouse). The cost will be extremely high. In addition, since the articles that are delivered in units of one case are stored in a state of being stacked on a pallet, wasteful work that does not add value such as palletizing work and depalletizing work is required. Expensive personnel costs (or equipment costs) and vast space are required.

[0006] Therefore, the object of the present invention is to reduce the loading and unloading capacity required for storage equipment by simplifying the storage and arranging route of articles, and also to create the added value of palletizing work and depalletizing work. An object of the present invention is to provide a storage and packing method for articles that can eliminate unnecessary wasteful work.

Next, an embodiment of the article storage / loading method of the present invention using the above-described article storage / loading facility will be described.

That is, based on the shipment status of each day, the first storage facility F or the second storage facility is produced at the production facility P at regular time intervals (for example, every one hour, every three hours, every day, etc.). The production amount of each type of article G stored in the facility 8 and the shipment amount of each type of article G shipped from the first storage facility F or the second storage facility 8 are made substantially the same (for example, The production amount and the shipment amount are set within a range of ± 20% of the production amount), and the production amount and the shipment amount are planned so that the production amount and the shipment amount are substantially synchronized with each other.

Further, the article storage scale of the first storage facility F for storing the articles G of a large quantity to be shipped among the articles G to be stored was calculated on the basis of the standard production pattern and the standard shipping pattern. The scale is required based on the imbalance between production and shipment. That is, if the production amount and the shipment amount can be always synchronized, the first storage facility F
The storage capacity of goods may be close to zero, but due to the fact that it is not preferable to greatly change the production speed depending on the shipping situation as well as the shipping situation depending on the arrival time of the delivery truck. Since it is difficult to perfectly synchronize the production amount with the shipment amount from moment to moment, in the present embodiment, the shipment amount of the article of the first storage facility F at a constant time is ± 20% of the production amount. It is set so that it can respond even if it fluctuates within the range.

In addition, each second storage of the first storage facility F
It is set up so that only the articles G of the same type are stored in the tributary line 1, and one or more second articles G are provided for each type.
The tributary line 1 (1 frontage or more) is allocated at a fixed location according to the required article storage scale.

Thus, the shipment amount of the product G of a certain type among the items G stored in the first storage facility F in a certain time zone is less than the production amount, and the product G is assigned to the first type. When the tributary line 1 of No. 2 is filled with the articles G, a part (excess) of the articles G of the article that is still being produced cannot be stored (stored) in the first storage facility F. The second tributary line 1 for each product after a certain period of time based on a trial calculation made based on the article storage scale of the first storage facility F, the planned production amount (scheduled production speed), the planned shipment amount (scheduled shipment speed), etc. When the first storage facility F is determined to have little empty storage space by predicting whether or not the product G will be full, the first storage facility F can be stored before the first storage facility is full. Cannot be stored (stored) in facility F And are controlled as an article G of varieties is expected to be to (stored in the first storage facilities F (housing) as well as) gradually stored in the second storage facility 8 (housing). Therefore, if the article G of the product type is stored (stored) in the second storage facility 8 after the second tributary line 1 is filled with the article G, (the articles stored in the first storage facility F are Since G is a product G of a product type with a large amount of shipment, that is, a product G of a product type with a large amount of production, the second storage facility 8 also needs a large storage capacity similar to that of the first storage facility F. By controlling so that the second storage facility 8 is gradually stored (stored), the stacker crane 9 for storing the articles G in the second storage facility 8 does not have a high processing capacity. can do.

Further, the article G is set to be stored in a free location in each article storage portion of the second storage facility 8, and the second storage facility 8 stores articles of a small variety in shipment quantity. In addition to storing G, the product G of the type with a large shipment amount, which cannot be stored in the first storage facility F as described above, is also stored.

It should be noted that although it is possible to set such that the goods G of a small quantity to be shipped are stored in the first storage facility F,
If the product G of the type having a small shipment amount (production amount) is set to be stored in the first storage facility F, an extremely large first storage facility F is required, and the facility cost is high. Since the first storage facility F can be effectively used and it is operated with a large amount of empty storage space, the goods G of the type having a small shipment amount are the second one.
It is designed to be stored only in the storage facility 8 of FIG.

Thus, the articles G produced in the production facility P are transported by the transport conveyor C in case units, and the transported articles G are transported in the first storage facility F and the second storage facility 8 in case units. It is designed to be stored at.

Further, the articles G of the type stored in both the first storage facility F and the second storage facility 8 at a certain time zone.
When the shipping amount of the above item exceeds the production amount, the article G of that type can be delivered from both the first storage facility F and the second storage facility 8.

The articles G stored in the first storage facility F and the second storage facility 8 on a case-by-case basis are controlled by the load assembling facility M in accordance with a shipping request, such as reverse order of delivery. Cases are taken out from the first storage facility F and the second storage facility 8 in units of cases and integrated on the second transfer conveyor 5, and the articles G of a desired product type are ordered in a desired order and in a desired number of cases for each shipping destination. Etc.

That is, when the arrangement intervals of the five rows of the second tributary lines 1 forming the first storage facility F arranged in parallel along the main stream line 2 are 700 mm, the uppermost stream is obtained. The distance from the second tributary lines 1e, 1j, that is, the offset value α, is 700 mm for the second tributary lines 1d, 1i adjacent to the second tributary lines 1e, 1j, and for the second tributary lines 1d, 1i.

Of the article Gi, the length of the article Gi is 280 mm and the extra space 4 is taken out.
Virtual space βi of the article Gi added with 00 mm, that is, 28
0 mm + 400 mm = 680 mm is set, and the time required for the virtual space βi set in the upper main line 2 to move, that is, 680 mm ÷ 266.7 mm / sec = 2.
Since the articles Gp in the first tributary line 6 are merged (taken out) at a timing after 16.3 seconds plus 5 seconds plus the merging time difference, the upper main stream line 2 is merged depending on the timing of merging. The length dimension of the article Gp is 590 mm and the extra space 40 is
The virtual space γp (590 mm of the article Gp added with 0 mm
(+400 mm = 990 mm) is set, and the virtual space γp is controlled so that the articles G are not merged from the second tributary line 1 on the upper stage side (set as an empty space). Further, the virtual space γp is set also in the main stream line 2 on the lower stage side in accordance with the timing (16.3 seconds after) when the articles Gp on the first tributary line 6 merge, and the virtual space γp on the lower stage side is set in the virtual space γp. It is controlled so that the articles G are not merged from the tributary line 1 of No. 2 (an empty space).

The article Gj taken out at the final end of the second conveyor 5 after the article Gp is the second tributary line in the same stage as the article Gi taken out at the last end of the second conveyor 5 ahead of the article Gp. The article G that is stored at No. 1 is taken out at the final end of the second conveyor 5 before the article Gp.
After taking out time to the mainstream line 2 excluding the offset value α of i, that is, 13.8 seconds + merging time difference, the time 2.5 seconds required for the virtual space βi of the article Gi to move and the hypothesis of the article Gp The time required for the space γp to move, that is, 9
90mm ÷ 266.7mm / sec = 3.7sec added 2
After 0.0 seconds + merging time difference, the article take-out command is issued so that the article Gj is taken out from the second tributary line 1j into the virtual space βj set in the main tributary line 2.
Is provided to the article take-out device 3 provided at the tip of the. The offset value α of the second tributary line 1j is 0 m
Since it is m, it is not necessary to add the offset value α to the above time.

The article Gj taken out at the final end is taken out to the mainstream line 2 excluding the offset value α and the merging time difference, that is, after 20.0 seconds, a phase difference of 2 seconds is added 2
2.0 seconds later, the offset value α of the second tributary line 1d
Minute 700 mm, that is, 700 mm ÷ 266.7 mm / sec =
The second tributary line 1d was added 24.6 seconds after adding 2.6 seconds.
An article take-out command is given to the article take-out device 3 provided at the tip of the second tributary line 1d so as to take out the article Gd from the main stream line 2. The following calculation is also performed in order to confirm whether or not there is a sufficient margin space in the main line 2 on the lower stage side. That is, after the article Gd is taken out before the article Gd is taken out to the downstream end of the main stream line 2 on the lower stage side, the take-out time to the main stream line 2 excluding the offset value α, that is, 9.3 seconds, the length of the article Gd The virtual space βd of the article Gd obtained by adding the margin space 400 mm to the size 280 mm, that is, 280 mm + 400 mm =
The time required for moving the virtual space βd set on the main line 2 by setting 680 mm, that is, 680 mm / 2
The value obtained by adding 66.7 mm / second = 2.5 seconds is 11.8 seconds later, and the taking-out time before adding this value and the offset value α minutes of the above-mentioned article Gd, that is, 22.0 seconds later. Comparing the above, it can be confirmed that there is a sufficient margin space in the main stream line 2 on the lower stage side, since it is later after 22.0 seconds described above.

As described above, the transport speed 266 of the main stream line 2 is calculated in the computer (not shown) during the time from the start of the packing of the articles G stored in the second tributary line 1 to the removal thereof. The value multiplied by 0.7 mm / sec is the value of each article G stored in the second tributary line 1.
Is the transport distance of each virtual space β from the start of load assembling to the removal. Therefore, the pulse encoder 23 attached to the line shaft 22 of the mainstream line 2
Is the transport distance of the virtual space β during one pulse of, and the virtual space β from the start of load alignment to the time when each article G is taken out
The value obtained by dividing the transport distance of is the pulse value from the start of the load alignment at which the respective articles G stored in the second tributary line 1 should be taken out. Then, the computer transmits the pulse value from the start of the load alignment and the number of the second tributary line 1 from which the respective articles G are to be taken out to a sequencer (not shown). The sequencer receiving the data stores the pulse value from the start of the load alignment and the number of the second tributary line 1 from which the article G should be taken out, and counts the pulses of the pulse encoder 23 at the same time when the load alignment is started. Start and control the air cylinder 35 of the article take-out device 3 provided at the tip of the second tributary line 1 that coincides with the commanded pulse value to take out a predetermined article G to the main line 2 To do.
