Consisted of.

Here, FIG. 1(b) shows a top view of a combination of the pallet storage shelf device of the present invention and one processing machine 30a.

The carry-out mechanism 10a carries the unprocessed article 29b from the lower pallet 5b or the upper pallet 5a to the processing machine 30a.

The carrying mechanism 10b carries the processed article 29a to the upper pallet 5a or the lower pallet 5b.

The guide rail 12a is connected to the unloading mechanism 10a and the loading mechanism],
A receiver for the processing machine 30a and the upper pallet 5a or the lower pallet 1-5b, which guide the movement and position of the object and carry in and out the articles 29, are provided between the transfer positions.

The carrying-out mechanism ○a and the carrying-in mechanism 10b are interlocked to prohibit carrying-in/out of the same pallet at the same time.

Next, the operation of the above configuration will be explained.

To store the unprocessed articles 29a in the storage shelf 1, the pair of pallets 5 are transferred from the storage shelf 1 to the elevator mechanism 3 by the transfer mechanism 4.

Next, the elevator mechanism 3 is lowered to the transfer position to the moving table 8 and the pair of pallets 5 are transferred onto the moving table 8.

The movable table 8 carrying the pair of pallets 5 lowers the pallet mounting table 8a and places the upper pallet 5a on the upper separation tool 6a of the separation mechanism 6.

Next, the moving platform 8 with the lower pallet 5b placed thereon is moved to a position 10 next to the unloading machine.

In this state, the unprocessed articles 29b are loaded onto the lower pallet 5b by the carry-in mechanism 10a of the carry-in/out mechanism 10.

After loading the goods 29b, the lower pallet h5b is moved to the moving table 8.
It moves to the position of the middle separation mechanism 6 of each storage shelf 1, raises the pallet mounting table 8a, and stacks the upper pallet 5a on the lower pallet 5b. In this state, the pair of pallets 5 are transferred to the elevator mechanism 3, the elevator mechanism 3 is activated, the pallets are raised to the shelf position for storage, and the pallets are stored on the storage shelf 1.

With the above steps, the preparation work for storing the unprocessed articles 29b in the storage shelf 1 is completed.

Next, the moving table 8 carrying the pair of pallets moves to the position of the separation mechanism 6 of the support 7 provided outside the storage shelf 1, lowers the pallet loading table 8a, and removes the upper pallet 5a from the upper separation mechanism. Place it on top of 6a. The pallet placing table 8a further descends and places the lower pallet 5b on the lower separating tool 6b.

The upper pallet 5a and the lower pallet 5b are separated by an upper separating tool 6, respectively.
a. After placing the pallets on the lower separation tool 6b, the moving platform 8 returns to the transfer position of the pair of pallets 5.

When the processing machine 30a starts processing, the control device 9 sends an article 29b required for processing to the elevator mechanism 3.
The shelf where the is stored is indicated.

Upon receiving the instruction, the elevator mechanism 3 moves to the shelf, uses the transfer mechanism 4 to transfer the pair of pallets 5 onto the elevator mechanism 3, descends to the transfer position to the transfer platform 8, and transfers the pair of pallets 5 onto the transfer platform 8. The pair of pallets 5 are transferred to the upper and lower pallets 5, and the upper and lower pallets 5a and 5b are placed on the separating mechanism 6 in the storage shelf l to complete the setting (the state shown in FIG. 3(a)).

A request to transport the article 29b to the processing machine 30a is sent to the control device 9.
When the article 29 is taken out, the moving table 8 moves to the position where the lower pallet 5b loaded with the requested article 29b is separated, raises the pallet loading table 8a, places the lower pallet 5b on the moving table 8, and carries out the article 29. The unprocessed article 29b carried to the person's position is carried out to the processing machine 30a by the carrying-out mechanism 10b (
(state of FIG. 3(b)).

Next, with the lower pallet on it, the movable table 8 returns to the position of the separation mechanism 6 where the upper pallet 5a was separated and held, raises the pallet mounting table 8a, and stacks the upper pallet 5a on the lower pallet 5b. The nolet mounting table 8a is lowered and the upper and lower pallets 5a, 5b are held by respective separating tools 6a+6b inside the storage shelf 1.

Next, the pallets 5 inside the support stand 7 are combined into a pair by the moving stand 8 and moved to the carry-out person's position. The article 29a after processing by the processing machine 30a is carried by the carry-in mechanism 10a and placed on the upper pallet 5a (third
Figure (C) state).

After this upper pallet 5a is paired with the lower pallet 5b, this pair of pallets 5 is carried out to the next process by a conveyor, crane, etc. provided on the support base 7 (not shown).

Even when processing is performed using only one processing machine 30a, the separation mechanism 6 is provided on the support stand 7 outside the storage shelf l, and the separation mechanism 6 inside the storage shelf 1 holds the workpiece. A pair of pallets 5 are used for carrying into the processing machine 30a and for taking out from the storage shelf 1, while a pair of pallets 5 held by the separation mechanism 6 of the support stand 7 is used for carrying out the next process. By using this as a tool, the processed article 29a can be sent to the next process at the same time as the process is completed, and the next process can be sent without loss of waiting time.

Note that the pair of pallets 5 inside the storage shelf 1 in the above embodiment may also be adapted to accommodate the article 29a processed by the processing machine 30a in the storage shelf 1 again, and can be changed arbitrarily depending on the working conditions.

Furthermore, when processing the article 29b using the processing machine 30a, it may take more than one hour per piece, but in such a case, the article is not carried into the processing machine 30a, but is carried out from the support base 7 and processed. It's okay.

[Second Embodiment] Next, FIG. 5 is a top view of a combination of the pallet storage shelf device of the present invention and two processing machines 30a and 30b.

The operation of storing the unprocessed article 29b on the storage shelf 1 is performed in the same manner as in the previous embodiment.

When the first processing machine 30a starts processing, the control "AM9"
Articles 29 required for processing for the elevator mechanism 3
The shelf where b is stored is specified.

Upon receiving the instruction, the elevator mechanism 3 moves to the shelf, uses the transfer mechanism 4 to transfer the pair of pallets 5 onto the elevator mechanism 3, descends to the transfer position to the transfer platform 8, and transfers the pair of pallets 5 onto the transfer platform 8. A pair of pallets 5 are transferred to.

The moving table 8 carrying the pair of pallets moves to the position of the separation mechanism 6 of the support 7 provided outside the storage shelf 1, lowers the pallet mounting table 8a, and places the upper pallet 5a on the upper separation device 6a. I'll ride it. The pallet mounting table 8a further descends and places the lower pallet 5b on the lower separation tool 6b.

The upper pallet 5a and the lower pallet 5b are separated by an upper separating tool 6, respectively.
a. After placing the pallets on the lower separation tool 6b, the moving platform 8 returns to the transfer position of the pair of pallets 5.

Next, the elevator mechanism 3 that has received the second shelf instruction goes up and the previous series of operations is performed again, and the upper and lower pallets 5a are placed in the separating mechanism 6 in the storage shelf 1.

5b and the set is completed (state shown in Figure 4 (a))
.

When a request to transport the article 29b to the first processing machine 30a is issued from the control device 9, the moving table 8 transfers the requested article 29b.
The lower pallet 5b loaded thereon is moved to the separated position, the pallet loading table 8a is raised, the lower pallet 5b is placed on the moving table 8, and the article 29 is carried to the unloading person's position, and the unprocessed article 29b is transferred to the unloading mechanism 10b. Then, it is carried out to the processing machine 30a (the state shown in FIG. 4(b)).

Next, with the lower pallet 5b placed thereon, the movable table 8 returns to the position where the lower pallet 5b is placed, raises the pallet placement table 8a, and stacks the upper pallet 5a on the lower pallet 5b. With the upper and lower pallets piled up, the movable table 8 returns to the article carryout position again.

The processed article 29a is carried by the carry-in mechanism 10a and placed on the upper pallet 5a (state shown in FIG. 4(c)).
.

When the processed article 29a is picked up, the moving table 8 returns to the position of the separating mechanism 6 where the upper pallet 5a was held separately, lowers the pallet loading table 8a, and loads the upper and lower pallets 5a,
5b and each separating tool 6a.

6b is held.

By the way, even if a request is issued from the second processing machine 30b for an unprocessed article 29b that is different from the article 29b being processed by the first processing machine 30a, another separation mechanism that is not used by the first processing machine 30a is used. The upper and lower pallets 5a and 5b held by the upper and lower pallets 5a and 5b held by the upper and lower pallets 6 (separation mechanism 6 provided on the support stand 7 portion outside the storage shelf 1 shown in FIG. 4(d)) are operated in the same manner as the first pallet. , transporting the unprocessed article 29b and the processed article 29
A can be brought in.

The above is an article 29b before being processed by two different processing machines.
I explained the case when requesting.

In this way, a plurality of pairs of pallets 5 are placed in advance in the loading/unloading machine 1.
Arranged around 10! By being able to store pallets in multiple columns, and carrying other pallets into and out of the processing machine side, it is possible to do so in parallel.
In particular, quick loading/unloading operations can be performed without any waiting time loss.

The above operations are shown in the flowchart of FIG.

[Effects of the Invention] According to the present invention, a pair of pallets are held in a separated state in the separation mechanism part as each pallet for pre-processing of articles, and the separation mechanism of the bracket is located near the loading/unloading mechanism for conveying to the processing machine. Since the configuration is such that a plurality of units are provided, the following effects can be obtained.

1. Just-in-time forwarding to the next process is now possible.

By having a separation mechanism installed outside the storage shelf hold the pallet loaded with processed items, the items can be taken out without disassembling the moving table or storage shelf, making transportation to the next process easy and eliminating time loss.

2. Processing machines or processing equipment can be easily added.

Because it is possible to separate two or more different types of goods without having to put pallets loaded with goods into or out of storage shelves, two or more types of goods can be separated.
It is now possible to supply and take out products from more than one processing machine or processing device without any time loss.

3. Can process large quantities of the same item.

It is possible to process similar items that cannot be placed on one pallet.

4. Easy interrupt production and high efficiency.

It is easy and efficient to urgently process small quantities of articles that are different from those on the separated pallets taken out from storage shelves.

It is easy to temporarily process large quantities of items that are not stored on storage shelves.

5. Good adaptability to factory environment.

Pallets loaded with goods can be placed on and taken out directly from the separation mechanism installed outside the storage rail, allowing goods to be carried in and out of the storage shelving system from the outside. Even if there are restrictions due to this, there is a high degree of freedom in the direction in which items can be carried in and out of the storage shelf device, so it has become possible to install it in locations that could not be installed in the past.
