Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates primarily to warehouse equipment for handling loads of different widths.

BACKGROUND ART Conventional warehouse equipment has been provided such as a first conventional example shown in FIG. 5, a second conventional example shown in FIG. 6, and an eighth conventional example shown in FIG. That is, in the first conventional example, the panels were set upright at a predetermined interval (■). The vertical frame Le111 and the arms attached to both sides of the vertical frame @υ form a shelf, and a fork that can run freely along this shelf and move in and out of the platform horizontally. The cargo receiver is equipped with a transfer device OQ. According to this, the cargo is transferred between the pair of arms (6) and the cargo handling platform @no by a combination of the movement of the transfer device, the lifting and lowering of the lifting platform, and the arrival and departure of the forks. The receiving is the passing.

In contrast to the first conventional example, in which the long side direction of the load is the frontage direction, that is, the direction of the spacing, the second conventional example uses shelves that can be stored with the long side direction as the depth direction. ing. Further, in the eighth conventional example, the long side direction of the load is the frontage direction. In other words, from each vertical frame (truss), a large number of cantilevers θ are provided in the vertical direction protruding toward the traveling path, and the cantilevers are set at a pitch that is the greatest common divisor of the length of the load. I try to accept the load (a).

Problems to be Solved by the Invention In the above-mentioned conventional examples, in the first conventional example, the length in the frontage direction of the load (g) that can be supported by the pair of left and right arms iia is determined; In order to handle loads of different lengths, it is necessary to use shelves with several different vertical frame spacings of 0η.

According to this, when a large amount of one type of cargo (c) is handled, even if the interval corresponding to the cargo (good) becomes full, other intervals remain empty, making it flexible. will be lacking. Furthermore, even when a long load (c) is supported at both ends by the arms (6), deflection of the load (goods) becomes a problem, especially in the case of a palletless system. On the other hand, in the second conventional example, it is possible to handle loads having various lengths in the long side direction at each frontage, as long as the length is within the range defined by the short side direction. However, in the second conventional example, the depth lengths of all frontages must be set so that the load (c) with the longest side can be handled, and therefore the planar occupied area of the entire warehouse facility is large. become. However, when handling short loads (goods) in the long side direction, a large dead space is created in the depth direction, and the planar efficiency is extremely poor. Moreover, the delivery device 01 handles the cargo (goods).
Therefore, it is necessary to prepare a large number of units. Furthermore, the third
In the conventional example, the vertical frame θυ to which the cantilevers 4 are attached is too large, which is uneconomical, and the sway of the shelf becomes a problem. In addition, since ``Uta'' is too flexible, it becomes complicated in terms of operation (control, etc.).

Means for Solving the Problems In order to solve the above-mentioned problems, the warehouse equipment of the present invention has vertical frames erected at predetermined intervals, and a reciprocal vertical frame connecting vertical frames adjacent on the left and right sides. A horizontal frame and a large number of cargo receivers arranged at predetermined pitches on these horizontal frames form an opening with a tool, and the cargo receiver has a fork that can move freely along this shelf and that can move in and out of the platform laterally. A transfer device is provided, the shelf is divided into a plurality of blocks, and the cargo receiver determines a reference stop position of the transfer device for each block.

According to the above-described configuration of the present invention, the cargo receiver operates the transfer device according to the length of the load to be loaded, so that the cargo receiver transfers the cargo to a predetermined stop reference position of the block where the load can be loaded most efficiently. The device can be stopped and the desired loading can be carried out.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 4.

(No. 1 is a shelf, (2) is a shelf (On the front side of No. 1, the shelf (

) (9f) (9g) (9h) (9i) (9j
) (9k) are modules that can coexist and are set so that the loss is minimized. The shelf (1) is divided into a plurality of blocks in the vertical direction, namely a first block θ1, a second block 00, and an eighth block Oa. The cargo receiver determines the stop reference position of the transfer device it (2) for each block C11 to (2). Here, when the arrangement position of the tool (8) in each cargo receiver is set to ~L, the stop reference position of the first block QQ is (A (to) (G) (J)
The stopping reference position of the second block α is (A) (
E) (1), the stopping reference position of the 8th block (2) is (

The cargo receiving and transferring device (2) includes a main body a3 that can freely travel back and forth on a fixed path (3), and a lifting platform (c) that is guided by a pair of front and rear supports forming a part of this main body. A plurality of (5 in this example) forks (16a) (16b) (16c) (16d) are arranged on this elevator platform oQ so that they can move in and out in the lateral direction.
(16e) and each fork (t6a) ~
Although (16e) is used for coming and leaving work in an integrated manner, the number of times used can be determined arbitrarily. In addition, each fork (16a) ~ (1
In 6e), adjacent cargo receivers can be inserted between the tools (8).

Outside the end of the shelf (1), a travel path (g) for a transport vehicle Qη that supports and conveys the loads (9a) to (9k) is formed in a direction perpendicular to the fixed path (3), Also, the transport trolley is 0.
7) and delivery device i! (2) Load (9a) between
The transfer route (a) of the transfer trolley 01 that transfers the receivers of ~(9k) is formed along a fixed route (3).The transport trolley qη is supported by the rail Q0 via wheels and a main body guided through a guide roller (with a guide roller);
on this main body (C), a pusher (E) that is movable laterally on the main body (C), and a pusher (E) that is arranged on the main body (C). The holding device is comprised of a pair of front and rear clamping plates (b) which are provided and can move toward and away from each other. The transfer trolley OI includes a main body 0υ supported and guided by wheels (7) on rails), a large number of idling rollers (3) and a main body Gll that form a support conveyance surface in the front and rear direction on this main body θυ. A stopper (to) that is movable up and down at the end on the travel route (g) side of It is composed of a plurality of lifting tools (2) that can be freely raised and lowered between the rollers) and a lifting drive device that raises and lowers these lifting tools (to) as a unit, and each lifting tool
The pitch between the cargo receiving tools (8) is set equal to the pitch (P) of the lifting tools (8), and the forks (16a
) to (16e) can enter.

Next, the operation of the embodiment described in - will be explained. Here, we will describe the action of putting the loads (9a) to (9k) transported by the transport vehicle θ onto the shelf (1), but due to the reverse action, &jJ (]
, ) can be taken out to the transport vehicle aη, and equipment for taking out may be provided outside the other end of the shelf (1). (c) The transport vehicle θ, which supports the loads (9a) to (9k) on it, travels along the traveling route (g) and is stopped opposite the end of the intended transport route slope. At this time, the clamping plates (b) move closer to each other to hold the loads (9a) to (9k), and at the same time centering.
In the transfer cart θ1 located on the side (G), the stopper and the lifting tool (埒) are moving downward and retracting, and the positioning tool (■) is moving away. Therefore, after moving the clamping plate (A) away, By operating the pusher (7), the load (9a) on the idle roller of the transport vehicle Q77
~(9k) will be transferred onto the idle roller (2) of the transfer cart 0.

After this transfer has been carried out, first, the stopper ζ→ is raised and projected, and the positioning tool (B) is moved closer to contact the loads (9a) to (9k), and the loads (9a1 to (9k) are brought into contact with the loads (9a) to (9k).
9k) are moved together. Moving load (9a) ~ (
9k) comes into contact with the stopper (to), and is thereby positioned using the surface of the stopper (to) as a reference plane, and is also held between the stopper (to) and the positioning tool (b). In this state, the transfer cart OI is run, and the cargo receiver is stopped at the operating position of the transfer device (2). Next, after separating the positioning tool @, the lifting tool (to) is raised via the elevating drive device.

This lifts the loads (9a) to (9k) upward relative to the idle rollers. The transfer device (2), which is stopped at the operating position, is at its lowering limit when the lifting platform is 0 o'clock. ) and between the idle rollers (2)
and the loads (9a) to (9k). At this time, the lengths of the loads (9a) to (9k) have been detected. This detection is performed by the amount of movement of the positioning tool (2), a phototube device, or various detection means in a previous step, and the detected value is input to the control section. Therefore, in the control unit, the blocks OQ to 0O into which the loads (9a) to (9k) are placed, and the stop reference positions (A) to (I-
) is determined, and based on that, the consignment is transferred to the delivery device (2)
becomes in a state where it can be controlled. The aforementioned fork (16a)
The protruding movements (16e) to (16e) are performed only as many times as necessary based on control. After protruding, the lifting platform OQ is raised,
The loads (9a) to (9k) on the lifting tool are received by the forks (16a h-(16e). Thereafter, the loads (9
a) to (9k) are drawn into the lifting platform θQ. Next, the cargo receiving and transferring device (2) is driven and stopped in accordance with the corresponding stop reference position (L) of the corresponding block OQ (to) based on a command from the control section. Then, by the protruding movement of the forks (16a) to (16e) and the descending movement of the lifting platform (to), the cargo receiver at the corresponding location is moved between the tools (8) and the cargoes (9a) to (9k) are moved. ) can be passed,
Thereafter, the forks (16a) to (16e) are moved in and out. Loads (9a) to (9k) are supported by a plurality of load receivers arranged at predetermined pitches (P) between the fixtures (8), but the number of supported loads depends on the length of loads (9a) to (9k). Depends on the size.

In Fig. 2, for example, only the shortest load (9a) is loaded on the upper side of the first block (II), and only the slightly longer load (9b) is loaded on the lower side. Depending on the ratio of the loads (9a) and (9b) to be handled, the load (9b) may be loaded on a part of the upper side, or the load (9a) may be loaded on a part of the lower side. Corresponding loads (9a) and (9b) may be mixedly loaded in the second block 01.
), the load (9c) (9d) (9e) (9f) (
In the eighth block (a), it is possible to mix loads (9h), (9i), (9j), and (9k).

When looking at the entire load (9a) to (9k), if the balance is uneven, the ratio of the blocks Od to 0 described above may be changed arbitrarily.

In the above embodiment, the blocks are divided in the vertical direction, but the blocks may be divided in the left-right direction, that is, on the frontage side.

Effects of the Invention According to the present invention configured as described above, the cargo receiver operates the transfer device according to the length of the cargo to be loaded on the shelf.
The cargo receiver can stop the transfer device at a predetermined stop reference position of the block where the cargo can be loaded most efficiently and perform the desired loading.

As a result, the following effects can be expected.

0 A plurality of loads can be loaded within a predetermined interval of sufficient length, with the long side direction being the frontage direction, and divided into multiple groups with common lengths in the long side direction, Since each group can be loaded in a correspondingly set block, loading can be performed with great flexibility, and the division into blocks simplifies operation (control).

The zero load is supported at multiple locations depending on its length by the load receiving tools placed at a predetermined pitch, making it possible to support the load without causing deflection.

0. Loading can be carried out efficiently in the left and right directions, and no dead space is created in the depth direction, thereby providing a shelf with good planar efficiency and a small occupied area.

0 Since the length is adjusted in the left and right direction, but not in the depth direction, each cargo can be handled even if one cargo receiver is a transfer device.

O Since the framework is composed of a horizontal frame and a vertical frame, each unit member can be small and inexpensive, and a rigid shelf that does not sway can be provided.

O The set ratio of each block can be arbitrarily and easily changed according to the ratio of loads to be handled, making it possible to achieve greater flexibility.
