Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a loading/unloading and storage method for loading and unloading cargo between a cargo transport device and a cargo storage warehouse, and its equipment.

Conventionally, this kind of work involved passing the load transported by a hanging conveyor to a chain conveyor, and then transporting the load to a handling area by the chain conveyor, and then loading and unloading the load by a loading/unloading device that can run along a shelf. The cargo was stored on the shelf, or the load on the shelf was transferred to a hanging conveyor by the reverse operation.

According to this, because loads are transferred frequently between devices, it is easy for loads to collapse and pallets to shift in position.
Also, quick work cannot be expected.

The present invention provides a cargo loading/unloading and storage method and its equipment that can solve the above-mentioned problems, and one embodiment thereof will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a cargo storage warehouse, in which a plurality of shelves 3 forming a plurality of vertically and horizontally divided storage spaces 2 are arranged in parallel with aisles 4 placed therein. Inside, there is provided a loading/unloading device 6 having a fork 5 that can run along the shelf 3 and can move up and down as well as move in and out in the lateral direction.

An incoming cargo handling area 7 is provided on one side of the three rows of shelves,
In addition, a loading/unloading handling area 8 is provided on the other side.Hereinafter, the loading handling area 7 side will be described, and since the other loading/unloading handling area 8 side has the same configuration, the details thereof will be omitted. .

In FIGS. 3 and 4, reference numeral 9 denotes a hanging type conveyor, which includes a trolley guide rail 12 for guiding a trolley 11 formed by connecting hangers 10, and a drive device 13 for driving the trolley 11 on this rail 12. This drive device 13 consists of a drive chain and a chain guide rail (only the rail is shown in the embodiment).

The hanger 10 consists of a gate-shaped member 14 and a pair of front and rear horizontal bars 15 that are connected in opposite directions from the lower ends of the legs, and the upper surfaces of these horizontal bars 15 are formed into an upward supporting surface 16. A guiding piece 17 is provided to protrude from the upward supporting surface 16.

Reference numeral 18 denotes a member whose both ends can be placed between the upward supporting surfaces 16, and suspends and supports the load 20 via a chain 19.

The hanging type conveyor 9 is constructed so as to approach the side of the shelf 3, and by reversing its drive device 13 at the side of the shelf 3, the trolley carry-in drive path 13A and the trolley carry-out drive path 13B are connected. and is formed.

Further, the trolley guide rail 12 has a reversible portion, and has an inlet side 12A and an unloader side 12B parallel to each other, and its end portion protrudes beyond the reversible portion of the drive device 13.

Between the hanging type conveyor 9 and the shelf 3, one end 21 thereof is provided.
a can be connected to the loading side rail 12A and the vertical axis 22A
A relay rail 21 whose other end 2lb can be connected to the carry-out side rail 12B by rotating around the relay rail 21 and its rotation drive device 23 are provided.

This rotation drive device 23 includes a vertical shaft 22 that is rotatably supported by a fixed frame 24 from the ceiling side, a pinion gear 25 fixed to the upper end of this vertical shaft 22, and a rank 26 that engages with this pinion gear 25. , a cylinder 27 that reciprocates this rack 26 in its length direction, a rotating frame 28 attached to the lower end of the vertical shaft 22, and a rotating frame 28 pivotally attached to the rotating frame 28 side that guides the rotation. It consists of a plurality of rollers 29 and a roller guide rail 30 attached to the fixed frame 24 side, and the relay rail 21 is supported by the rotating frame 28.

That is, the relay rail 21 is supported by a rail 31 integrated with the rotating frame body 28 via a trolley 32, and is configured to be movable in a lateral direction orthogonal to the length direction thereof, and the movement is performed by a cylinder 33. It will be done.

The traveling path 34 of the loading/unloading device 6 extends to the side of the rotary drive device 23, and the fork 5 is
The hanger 10 supported by the relay rail 21 is configured to be able to move up and down as well as move in and out between the upward supporting surfaces 16.

The shelf 3 is provided with a pair of support parts 35 having the same arrangement shape as the upward support surface 16.

That is, the support part 35 is arranged in a continuous manner from the vertical frame 36 to form the divided storage space 2 and at the same time perform a supporting function thereof, and furthermore, a guide piece 37 is provided protruding from the upper surface of the support part 35 .

In FIG. 1, 38 indicates the main hanging type conveyor.

The loading/unloading and storage operations will be explained below.

The hanger 10 supporting the load 20 via the member 18 is
As shown in FIGS. 1 and 2, the main suspended conveyor 38
is transported to the side of the incoming cargo handling area 7, and transferred to the incoming side rail 12A of the hanging conveyor 9 via the trolley 11, and receives the power of the drive device 13 to move the trolley incoming drive path 13A. move.

When reaching near the end of the carry-in drive path 13A, the reversing structure of the drive device 13 causes the hanger 10 to become non-passive, and thus the hanger 10 stops at the tip side of the carry-in side rail 12A.

At this time, one end 21a of the intermediate rail 21 is connected to the carry-in side rail 12A due to the storage of the cylinder 27 and the extension of the cylinder 33. Therefore, by operating the extrusion device and the retraction device (none of which are shown),
As shown in FIG. 3, the hanger 10 can be transferred to the relay rail 21 and positioned on the side of the travel path 34.

In this state, the cargo loading/unloading device 6 is moved to the side of the rotary drive device 23, and between both upward supporting surfaces 16 and the member 1 is moved.
By protruding the fork 5 below 8, then raising the fork 5 to lift the member 18, and then retracting the fork 5, the load 20 is directly transferred to the hanger 10 via the member 18. can be received at.

After the cargo 20 is brought to face the desired compartment storage space 2 by the movement of the cargo loading/unloading device 6 and the raising of the fork 5, both ends of the member 18 are moved to the support portion by the protruding and descending movements of the fork 5. 35 to receive the load 20.
can be stored on shelf 3.

The empty hanger 10 causes the intermediate rail 21 to escape laterally with respect to the carry-in rail 12A as shown by the imaginary line A in FIG. 4 due to the contraction of the cylinder 33, and the rack 26 and After rotating the vertical shaft 22 via the pinion gear 25 and rotating the rotating frame 28 by 180 degrees around the vertical axis center 22A to change the phase of the relay rail 21, the cylinder 33 is extended as shown in the imaginary line B. By connecting the other end 21b of the intermediate rail 21 to the unloading rail 12B, the unloading rail 12
The trolley discharge drive path 13B can be run through B and can be rejoined with the main hanging conveyor 38.

In addition, at the position shown by the imaginary line, it is also possible to perform cargo storage work using the cargo loading/unloading device 6 provided on the side of the position.

The work is also carried out in the reverse order to the above at the other loading and unloading handling area 8 side, so that the loads 20 in the shelves 3 are transferred to the empty hangers 1.
It can be transferred to 0.

As described above, according to the loading/unloading and storing method of the first invention described in the embodiments, loading and unloading between the hanging type conveyor and the shelf is carried out with respect to the member that suspends and supports the loading. This can be done by directly applying the fork of the loading/unloading device, which reduces the number of times the load is transferred and prevents the load from collapsing or shifting the position of the pallet. Furthermore, by employing the cargo loading/unloading and storage equipment of the second invention, the aforementioned method can be reliably carried out with a simple and easy structure.
