Abstract

PROBLEM TO BE SOLVED: To provide a pallet rack picking mechanism capable of solving the following problems: (a) operation using a fork lift is needed, so an operator needs the operational skill thereof for picking, (b) high-performance picking operation cannot be achieved because the operator must go around racks one by one by operating the fork lift even if a large amount of loads must be picked in a short time, which are found in a general method of using a folk lift with a picking stage for carrying out a small lot of load from a pallet rack. SOLUTION: This pallet rack picking mechanism is formed so as to be vertically movable by hanging a stage 6 from a ceiling above a passage 2 between pallet racks 1 disposed so as to face each other. The stage is comprised so as to have a length large enough to reach a plurality of racks 3 of pallet racks in the right/left direction and move along the passage, thus it is possible to attain more effective picking.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a picking mechanism for picking up goods from a pallet rack used as a pallet unit load storage device.

[0002]

2. Description of the Related Art Conventionally, in the case of carrying out a small exit from a pallet rack, for example, a method using a forklift with a picking table as shown in FIGS. 4 and 5 is generally used. That is, FIG. 4 is an explanatory diagram of the pallet rack viewed from the front, and FIG. 5 is an explanatory diagram of the pallet rack viewed from the side. Sign a
The pallet racks indicated by are arranged facing each other with a passage b therebetween, and each pallet rack a is provided with shelves c at the top, bottom, left and right, and the load e is stored on each shelf c by the pallet d. In the case of carrying out a small-shipping operation in such a pallet rack a, as shown in the figure, an operator operates a forklift g provided with a picking table f and passes a passage b.
And picks up the load e from the pallet d directly on the picking table f after reaching the predetermined position.

[0003]

However, such a picking method has the following problems. a. Since work by a forklift is necessary, the operator also needs forklift operation skills for picking work. b. Even if you pick a lot of cargo in a short time,
High-capacity picking work cannot be performed because a forklift must be operated to rotate one shelf at a time. Therefore, an object of the present invention is to solve such a problem.

[0004]

According to the present invention, there is provided a pallet rack picking system in which a stage is suspended and supported from the ceiling side in a passage between pallet racks arranged opposite to each other so as to be able to move up and down. Suggest mechanism.

In the present invention, it is proposed that the stage has a length extending over a plurality of shelves in the left-right direction of the pallet rack.

In the present invention, it is proposed that the stage is suspended and supported so as to be movable along a path.

According to the present invention described above, the operator gets on the stage suspended and supported from the ceiling side, raises and lowers the height so as to be positioned on the desired shelf of the pallet rack, and then adjusts the height. Pallet racks
While moving on the stage, the load on the pallet of the shelf at that stage can be directly picked. Therefore, no special technique such as a forklift operation technique is required, and anyone can easily carry out the small-lot exit operation in a short time. At this time, if the length of the stage is configured to span a plurality of shelves in the left-right direction of the pallet rack, or if the stage is suspended and supported so as to be movable along the passage, the worker can move the pallet rack in the left-right direction. Picking work can be freely performed over a plurality of shelves. On the other hand, if you go up the stage,
Since the work space of the forklift can be configured in the passage, the pallets loaded with the forklift can be quickly stored in each shelf.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. FIGS. 1 and 2 show the mechanism of the present invention in a state where an unloading operation is being performed. FIG. 1 is an explanatory diagram viewed from the front, and FIG. 2 is an explanatory diagram viewed from the side. FIG. 3 is an explanatory view of the mechanism of the present invention as viewed from the front, showing a state where a storage operation is being performed.
In these figures, reference numeral 1 denotes a pallet rack, and the pallet rack 1 is installed so as to be opposed to each other with a passage 2 therebetween. The load 5 is stored on the shelves 3 by pallets 4. Reference numeral 6 denotes a stage. The stage 6 is configured to be suspended from the ceiling side of the passage 2 so as to be able to move up and down. In this embodiment, the stage 6 is supported by a cylinder device 8 suspended from an upper beam member 7 constituting the pallet rack 1 so as to be lifted and lowered. And in this embodiment,
The cylinder device 8 is supported on the upper beam member 7 by a rail member 9 configured along the passage direction so as to be movable in the direction along the passage 2. As a moving mechanism of such a cylinder device 8, for example, a mechanism used for an overhead crane or the like can be applied. Thus, the stage 6 can be moved up and down by the cylinder device 8 and can move in the direction along the passage 2.

In the above configuration, an operator rides on the suspended stage 6 and operates a control device arranged at an appropriate position on the stage 6 or the like, and sets the height on the shelf 3 of a desired stage of the pallet rack 1. After adjusting to position, stage 6
While moving upward, the load 5 on the pallets 4 of the opposing shelves 3 can be directly picked. At this time, as shown in FIG. 2, if the length of the stage 6 is configured to extend to a plurality of shelves 3 in the left-right direction of the pallet rack 1, a plurality of shelves in the left-right direction at one stop position of the stage 6. 3 picking operation can be performed. The picking operation for the shelf 3 at a position where the picking operation cannot be performed at a certain stop position can be performed by moving the stage 6 up and down in the height direction to change the position, and in the lateral direction, the stage 6 can be moved. It can be performed by moving in the direction of the passage 2 and changing the position. In the picking operation described above, even if the operator performing the picking operation operates the stage 6 himself, the operation is performed on the stage 6.
No special operation skills are required because only the lifting and lowering operations are performed. For this reason, the picking mechanism of the present invention allows anyone to easily carry out a small-lot exit operation in a short time. Next, as shown in FIG. 3, if the stage 6 is raised to a predetermined height, a work space for the forklift 9 can be formed in the passage 2. 3 can be quickly stocked.

[0010]

As described above, the present invention has the following effects in picking work on a pallet rack. a. By moving the stage up and down and / or moving along the direction of the passage and stopping at a predetermined position, any of the opposing pallet racks moves on the stage, and the pallets on the shelves of that stage are moved. The above load can be picked directly. b. Therefore, no special technique such as a forklift operation technique is required, and anyone can easily carry out the small-lot exit operation in a short time. c. If the stage is raised, a work space for the forklift can be formed in the passage, so that the pallets loaded with the load by the forklift can be quickly stored in each shelf.
