Abstract

PURPOSE:To enhance cargo shifting work efficiency in handling cargoes, with various widths, by varying the carriage stoppage level by the distance between the upper and lower cargo supporting surfaces so that no matter what cargo width may be, large or small, the cargo can be shifted by being guided at its both right and left ends by a pair of right and left guides. CONSTITUTION:When a cargo 2 with large width stored in compartment 3 of a shelf 1 is to be delivered, a crane lifting carriage 10 is lifted/lowered first so that cargo receiving pieces 7a and 7b are positioned flushed with an upper supporting surface 13 of the carriage 10 at the exact side of the compartment 3. Next, a shifting means 11 is moved toward innermost of the compartment 3 and then lifted until its locking piece 16a is engaged with a counter-locking piece of the cargo 2. Further, the shifting means 11 is moved to this side and the cargo 2 is extracted onto the upper supporting surface 13. Meanwhile, when a cargo with small width in compartment 5 is delivered, the carriage 10 is lifted/ lowered until cargo receiving pieces 7a and 7b in the compartment 5 is positioned at the same level with a lower supporting surface 12 on the carriage 10 at the exact side of the compartment 5. After this, the cargo 4 is extracted in the same manner as above.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a loading/unloading crane used in automated warehouses, which safely transfers both small and large loads while being guided by a pair of left and right guides. To provide a loading/unloading crane for an automatic warehouse, which has a simple structure and does not require a movable guide that changes the interval according to the width of the load as in the past.

Hereinafter, one embodiment of the present invention will be described based on the attached illustrative drawings. Reference numeral 1 denotes a shelf installed beside a certain travel route of an automatic warehouse loading/unloading crane, and a section for storing a large amount of cargo 2. 6 and a section F[Q5 for storing small-width cargo 4. Each section 6.5 has a pair of left and right cargo receivers 7a installed between a pair of front and rear columns 6, respectively.

7b, and a pair of left and right stoppers F3a and 5b attached to the rear column 6. The loading/unloading crane is equipped with a carriage 10 that is supported on a support 9 so as to be able to rise and fall.
．． A load pushing/pulling transfer means 11 is provided which is movable in the far and near direction with respect to 5 and can be raised and lowered, and furthermore, this transfer means 11
A pair of left and right lower support surfaces 12 that support a small load 4 and a pair of left and right upper support surfaces that support a large load 2 at a higher position than the lower support surfaces 12 are provided on both the left and right sides of the movement path. A pair of left and right lower guides 14 are located between the surface 1S and the upper and lower support surfaces 12 and 13 and guide both left and right sides of the small-width load 4, and a pair of left and right lower guides 14 are located between the upper and lower support surfaces 12 and 13 to guide the left and right sides of the small-width load 4, and A pair of left and right upper guides 15 are provided for guiding both left and right sides of the upper guide 15. Since the transfer means 11 is well-known, illustrations and explanations of its support structure and drive structure will be omitted; however, in this embodiment, a pair of front and rear locking pieces 16a, 1
Of the locking pieces 6b, only the locking piece 16a located on the illustrated shelf 1 side is used. Of course, when the shelves 1 are erected on both sides of the crane traveling route, both the locking pieces 16a and 16b are used. In addition, the large load 2 and the small width load 4 are provided with inverted wave locking pieces 17a and 17b that can be freely engaged and detached from the locking pieces 16a and 16b at both front and rear ends thereof. In the example, the locked piece 1 located on the crane travel path side
Only 7a is used.

To explain how to use it, when pulling out a large load 2 stored in the compartment 6 of the shelf 1 onto the elevating carriage 10 of the crane during unloading work, run the crane and move the carriage 10 to WR. As shown in Figures 2 and 4, cargo receivers 7a and 7b in the compartment 6 are located directly next to the compartment 6 that stores the large cargo 2 to be shipped.
and the upper support surface 15 on the carriage 10 are positioned at the same level, and in this state, the transfer means 11 is placed on the lower support surface 15.
Move it to the compartment 6 side at a lower height than the locking piece 16
A is positioned directly below the locked piece 17a of the cargo 2 to be shipped. Next, the transfer means 11 is raised and the locking piece 16a is
is engaged with the locking piece 17a, and then the transfer means 11 is moved backward, so that the large load 2 to be discharged stored in the compartment 6 is moved to the upper side of the carriage 10 by the locking piece 16a. It is pulled out onto the support surface 13. At this time, the load 2 is moved between the left and right pair of upper guides 15 in the lateral direction (crane traveling direction) with respect to the load unloading direction.
There is no possibility that the position will shift or the direction will change.

When pulling out the narrow load 4 stored in the compartment 5 of the shelf 1 onto the elevating carriage 1o of the crane, the crane is moved and the carriage 1o is elevated and moved along the imaginary line in Fig. 1 and the imaginary line in Fig. 3. As shown in FIG.
a, 7b and the lower support surface 12 on the carriage 1o are positioned at the same level, and in this state, the transfer means 11 is moved to the compartment 5 side at a height lower than the lower support surface 12, and its locking is performed. The piece 16a is positioned directly below the locked piece 17a of the cargo 4 to be shipped. Next, the transfer means 11 is raised to engage the locking piece 16a with the locked piece 17a, and then the transfer means 11 is moved backward to remove the goods stored in the compartment 5 that are to be delivered. A narrow load 4 is pulled out onto the lower support surface 12 of the carriage 10 by the locking piece 16a. At this time, by moving the load 4 between the pair of left and right lower guides 14, the load 4 does not shift in position or change its orientation in the lateral direction (crane traveling direction) with respect to the load unloading direction.

When carrying a large load 2 or a small load 4 on the carriage 10 into the compartment 6 or 5 on the shelf 1 during the warehousing operation, a support surface that supports the load 2 or 4 to be handled in the same manner as in the above-mentioned unloading operation is used. 12 or 15 and ward ii! With the cargo receivers 7a and 7b of Ii3 or 5 located at the same level, or with the support surface 12 or 15 on the carriage 10 side slightly higher, the cargo 2 or 4 can be pushed into the compartment 6 or 5 of the shelf 1. At this time as well, the load 2 or 4 is pushed toward the shelf 1 while its movement direction is regulated by the guides 14 or 15 located on both its left and right sides.

Is the cargo transported between the loading/unloading platform or conveyor placed next to the crane's home position and the crane's elevating carriage 1o that is stopped at the crane's home position? Alternatively, the work of transferring the load 4 can be carried out in the same way as the work of transferring the load between each compartment 6 or 5 of the shelf 1 and the lifting carriage 10'' described above.

It should be noted that although the transfer work of the load 2 or 4 between the carriage 1o and the shelf 1 etc. is carried out only by the transfer means 11 provided with the locking piece 16a, the lower support surface 12 and the It is also possible to arrange a pair of left and right IT forwarding conveyors on the upper support surface 15, respectively, and to transfer the load by the joint action of the locking pieces 16a of the transfer means 11 and the conveyors. .

In this way, the load transfer device C between the carriage 10 and the shelves etc. may have any configuration.

The loading and unloading crane for automatic warehouses of the present invention can be implemented as described above, and has a lower support surface that supports a narrow load on a carriage that can be raised and lowered, and a lower support surface that supports the load on both the left and right sides of this support surface. A pair of left and right upper support surfaces that support a large load are provided at a higher position than the surface, a pair of left and right lower guides that guide the left and right sides of a small load between the upper and lower support surfaces, and the upper side. A pair of left and right upper guides are installed at a higher position than the support surface and guide large loads on both sides, and small and large loads are moved along the guides to move these loads between shelves, etc. Since the carrier is equipped with a transfer device for delivering and receiving the load, the stop level of the carrier slider can be simply changed by the distance between the upper and lower support surfaces, depending on whether a small load is being handled or a large load is being handled. Whether it is a small load or a large load, it can be transferred by being guided by a pair of left and right guides on both sides, and the position of the transferred load can be shifted laterally or in the wrong direction. This allows the transfer work to be carried out safely and at all times while preventing changes in the contents. In addition, there is no need to change the distance between the pair of left and right guides depending on the width of the load to be handled as in the conventional case, and since fixed guides are provided, the structure is extremely simple and can be implemented at low cost.
