Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applied to an automated warehouse or the like that handles loads of many items.
The present invention relates to a multi-item mixed pallet transfer device that receives a mixed pallet in which multiple items are mixedly loaded from a carry-in conveyor and transfers a desired item in a unloading conveyor.

[Prior Art] Conventionally, in an automatic warehouse that handles loads of many items, there is a type in which loads of many items are mixed and stored on one pallet. ,
The pallet on which the desired items are mixed is conveyed to the delivery port, and the desired items are selected and delivered from the delivery port.

[Problems to be Solved by the Invention] However, in the above-mentioned automated warehouse, since the selection of the load at the delivery port is performed manually, there is a problem that labor saving of the selection and automation of delivery cannot be performed.

The present invention was devised to solve the above-mentioned problems, and automatically selects a load of a desired item from a pallet in which loads of a large number of items are mixed and transfers it to a carry-out conveyor so that it is automatically delivered. It is to provide a transfer device for a multi-item mixed pallet that can be used.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention receives a mixed pallet in which loads of multiple items are mixed from a carry-in conveyor and transfers a load of desired items to a carry-out conveyor. In a pallet transfer device, a parent pallet is formed on four grid-shaped frames and is transferred by the carry-in conveyor, and a child pallet is placed on each frame hole of the parent pallet. A mixed pallet, a swivel base rotatably provided between the carry-out conveyor and the carry-in conveyor, a pair of chain conveyors provided on the swivel base and receiving the parent pallet from the carry-in conveyor, and both of them. Elevator that is installed between the chain conveyors and inserts the desired child pallet on the received parent pallet into the carry-out conveyor to insert it through the frame hole of the parent pallet. It is configured to include a conventional transfer roller conveyor.

[Operation] According to the above configuration, loads of many items are mixedly loaded on the child pallet, and the child pallet is placed and stored on the parent pallet.

When unloading a cargo, the parent pallet with the desired items mixed is transferred by the carry-in conveyor, and after receiving the parent pallet from the carry-in conveyor by the chain conveyor, the swivel base is used to transfer the desired items to the carry-out conveyor. After turning, the child pallet on which the desired item is placed is transferred to the carry-out conveyor by the transfer roller conveyor, and then the child pallet may be carried out to the exit port by the carry-out conveyor and taken out.

In this way, since only the child pallet on which the desired item is placed can be automatically transferred to the carry-out conveyor, it is possible to automate the load selection and warehousing, and save labor.

[Embodiment] An embodiment of the present invention will be described with reference to the accompanying drawings.

On the other hand, the pair of chain conveyors 10 is provided with a pair of chain conveyor frames 15 across the center of the swivel base 3 as shown in FIGS. 2 and 3, and both ends of the chain conveyor frames 15 are provided. A chain 17 for carrying is hung endlessly on a chain wheel 16 of the part, and these chains 17 are connected to a chain drive motor 19 via a power transmission device 18.

On the swivel base 3, a plurality of telescopic lifting jacks 20 for supporting the chain conveyor frame 15 to be lifted up and down are provided. The lifting jacks 20 are provided with transmission shafts 21, 22 and a transmission device 23. It is connected to a chain conveyor lifting motor 24.

Further, as shown in FIG. 1, four transfer roller conveyors 11 are formed between the two chain conveyors 10 so that the frame holes 12a of the parent pallet 12 of the mixed pallet 9 can be inserted between them. The transport direction of each roller conveyor 11 is driven in a direction orthogonal to the transport direction of the chain conveyor 10. Each roller conveyor 11 has
As shown in FIG. 2 and FIG. 4, a rotary drive motor 25 for individually rotating these is provided,
On the swivel base 3, as shown in the drawing, a plurality of telescopic lifting jacks 27 for supporting the conveyor frame 26 of the transfer roller conveyor 11 in a vertically movable manner are provided. The lifting jack 27 is connected to a roller conveyor lifting motor 31 via transmission shafts 28, 29 and a transmission device 30, and each transfer roller conveyor 11 is positioned on the chain conveyor 10 during its lifting. The parent pallet 12 is inserted through the frame hole 12a, and the child pallet 13 positioned on the inserted frame hole 12a
And the desired child pallet 13 is transferred to the carry-out conveyor 2.

Further, as shown in FIG. 1, on the swivel base 3, the mixed loading pallet 9 is provided on the peripheral portion thereof from the carry-in conveyor 1 to the chain conveyor 10 or from the transfer roller conveyor 11 to the carry-out conveyor 2. Roller conveyors 32, 33, 34, 35 for moving are provided for moving.

Next, the operation of this embodiment will be described.

In an automated warehouse that handles loads of many items, loads of many items are mixedly loaded on a child pallet 13 to which symbols (for example, A, B, C, D, etc.) are attached in advance as shown in FIG. It is placed on the parent pallet 12 and stored in a storage shelf (not shown) or the like.

When the stored goods are to be unloaded, the child pallets 13 (A, B, C, D) on which the child pallet 13 (for example, A) on which the desired item to be unloaded is placed are mixed. The parent pallet 12 on which the 13 is placed is taken out from the storage rack by a crane (not shown), transferred onto the carry-in conveyor 1 and conveyed to the swivel base 3 (Fig. 1), and the parent pallet 12 on the carry-in conveyor 1 is chained. The conveyor 10 receives and lowers the chain conveyor 10 to position the frame hole 12a of the parent pallet 12 on the transfer roller conveyor 11 (FIGS. 6 and 8 (A)). After that, the swivel base 3 is set to 90 so that the child pallet 13 of the symbol A of the desired item is positioned toward the carry-out conveyor 2.
After rotating, the transfer roller conveyor 11 is moved to the parent pallet.
After inserting and raising 12 frame holes 12a to raise the child pallet 13 located on the frame hole 12a (FIG. 8 (B)), the child pallet 13 of the symbol A of the desired item is placed. The transfer roller conveyor 11 is driven and transferred to the carry-out conveyor 2 via the transfer conveyor 33 (Fig. 7). The child pallet 13 having the symbol A may be conveyed by the carry-out conveyor 2 and discharged from a discharge port (not shown).

It should be noted that the child pallet 13 and the parent pallet 12 on which the loads of the desired items are mixedly loaded and taken out or selectively transferred are automatically performed by a control device not shown.

As described above, since the load of the desired item can be automatically selected and transferred to the carry-out conveyor 2, the load of the desired item and the warehousing can be automated, and the labor of the work can be saved.

[Effect of the Invention] According to the present invention, in an automatic warehouse that handles loads of many items,
Since the pallet containing many items of load is received from the carry-in conveyor and the load of the desired item is transferred to the carry-out conveyor, load selection and shipping work are automated, and labor saving of the work can be achieved. Shows excellent effects.
