CONSTITUTION:In a stocking/shipping system having a loop transportation truck 7 at the front face of stocking/shipping conveyor 2, shipping station 22 is arranged at the extended position of shipping side conveyor 2b while holding a loop track 3 then said conveyor 2b and the station 22 are coupled linearly through said truck 7. Consequently, when shipping large amount of cargoes at once, they can be shipped directly resulting in efficient bulk shipping work.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a loading/unloading device for an automated warehouse equipped with a loop carrier.

[Conventional technology]

Figure 2 shows an example of a loading/unloading device for an automated warehouse equipped with a loop conveyor.
), a large number of automated warehouses are installed in parallel, (3) is a rail provided in a long loop shape in a perpendicular direction in contact with the front end of the above-mentioned loading/unloading conveyor (2), (4) is a rail (3) ) is placed on the opposite side of the automated warehouse fl), and (
5) indicates the receiving device (4) (the shipping device installed in parallel).

A drive tube (6) is installed along the rail (3) between the automated warehouse (11 and the receiving/shipping device (4) +5).
A loop conveyance cart (7) is provided which is driven to travel by the drive tube (6). Loop transport vehicle (as shown in Figures 6 and 4, the drive wheel (8) converts the rotational force of the drive tube (6) into propulsive force by contacting the drive tube (6) in an inclined state. , a traveling wheel (9) for traveling on the rail (3), a guide wheel aυ in contact with the guide rail OQ, and a pallet holder for receiving the cargo loading pallets α is equipped with rollers (131 and a movable stopper I).
is provided on the top surface.

Further, in the above, the conventional receiving device (4) includes a plurality of receiving stations (each having a turntable α9).
IQ and empty pallet supply (and stacking) machine ←η are arranged together. Further, the shipping device (5) includes a plurality of shipping stations (181) and an empty pallet stacking machine a9 arranged together.

In the conventional warehousing/unloading device, the cargo carried into the receiving station (4) is transported onto the pallet receiver of the loop carrier (7) on rollers (13), and then moved in the direction of the arrow to be stored. Warehouse (1) loading/unloading conveyor (2)
It is stopped at the position and stored in the automatic warehouse (1) via the warehouse conveyor (2). Also, when leaving the warehouse, the cargo is cut out onto the cart (7) that is stopped in front of the loading/unloading conveyor (2), and then the cart (7) is run in the direction of the arrow and placed in front of the shipping station (5). It will be stopped and shipped.

In such devices, it is often necessary to take out a large amount of cargo at one time, but in the conventional method, it is necessary to run and stop the trolley (7), and cut out the cargo onto the trolley (7). , furthermore the trolley (power running, stopping and the trolley (
7) Since it takes time to take out the cargo on top, there is a problem in that it is not possible to efficiently remove a large amount of cargo at once.

[Problem that the invention seeks to solve]

The present invention is an attempt to make it possible to efficiently unload a large amount of cargo from a warehouse at once in an automatic warehouse loading/unloading device equipped with a transport vehicle that travels in a loop.

[Means for solving problems]

The present invention provides a warehousing and retrieval device equipped with a loop conveyor that moves along a loop-shaped track in front of a warehousing and retrieval conveyor installed in an automated warehouse, in which a warehousing-side conveyor of the warehousing and retrieval conveyor is mounted across the loop track. A shipping station is installed at an extended position, and the delivery side conveyor and the shipping station can be connected linearly via a loop carriage.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of the present invention, in which, as in the case of the conventional method, a loop-shaped carriage (7) is installed in front of the loading/unloading conveyor (2) of an automated warehouse (1). A rail (3) and a drive tube (6) are provided.

In the above configuration, the loading and unloading conveyors (2) of the automated warehouse (1), which are installed in large numbers so that the cranes travel at mutually spaced positions, are alternately moved between the loading side (2α) and the loading side (2b).
), and sandwiching the loop rail (3), an automated warehouse (
1), the exit side conveyor (2b
), an input/shipping station (21) and a shipping station (2) are provided as appropriate. Further, inside the loop of the loop rail (3), an intermediate conveyor (c) is provided at a position on a line that linearly connects the exit conveyor (2h) and the receiving/shipping station CD and the shipping only station (22). I241 in the middle shows an empty pallet transport conveyor, and (c) shows an empty pallet stacking machine.

In the above, when the cargo is normally stored, the cargo is carried into the loading/unloading station 0D, is placed on the loop transport vehicle (7), is transported along the loop rail (3), and is transferred to the automated warehouse (1) where it is stored. After stopping in front of the corresponding warehousing side conveyor (2a), it is warehousing.

In addition, after cutting out the baggage onto the loop conveyor (7) stopped just before the exit side conveyor (2b),
) and stops at the shipping station (position 22J) to unload the warehouse.

In the above case, when a request is made to take out a large amount of cargo at once, each loop conveyor (7) is moved between the exit side conveyor (2b) and the receiving/shipping station QD and the shipping station (24). Thereby, it is possible to directly unload cargo from the automated warehouse (1) in a straight line, thereby greatly improving the efficiency of unloading work.

It should be noted that the present invention is not limited only to the above embodiments.
In addition, the input and output sides of the loading and unloading conveyor can be freely selected, the number of intermediate conveyors, each methion, and loop conveyor can be changed arbitrarily depending on the situation, and the drive tube drive system is used. Although the example is given for a loop transport vehicle, other drive systems such as self-propelled vehicles can be similarly applied as long as they can travel along a loop track such as a rail or a guide line buried under the floor surface. In this case, we have shown an example of increasing the unloading capacity by setting up a receiving/shipping station and simultaneously unloading through all stations, but it is also possible to use the receiving side as a receiving-only station, It goes without saying that the intermediate conveyor can be omitted by making the parallel parts close to each other, and that various other changes can be made without departing from the gist of the present invention.

〔Effect of the invention〕

As described above, according to the loading and unloading device for an automatic warehouse of the present invention, when a large amount of cargo is to be unloaded at once, the unloading conveyor and the shipping station are connected in a straight line via the loop carrier. Particularly, it is possible to directly ship the cargo, and therefore, an excellent effect can be achieved in that efficient large-volume unloading work is possible.
