Description

  The present invention relates to a facility for high-rise article shelves, and relates to a technique for safely and efficiently performing warehouse operations without increasing the floor area.

  Conventionally, when storing items at a high place on a high-rise article shelf or taking out articles stored at a high place on a high-rise article shelf, as shown in FIG. 7, an article shelf 53 is installed across a plurality of rows. A floor 52 (hatched portion) is provided on the second floor portion of the accommodation facility 51 to be used, and an operator goes up and down the second floor 52 using a staircase or the like.

On the other hand, as a device that is not intended for work on high-rise article shelves, but works out of reach for cultivation management, fruit harvesting, etc. in facility horticulture, etc., a work carriage equipped with a step board that can change the height, There is known a work moving device that is connected to a transport cart that can load an article, and that can be run on a track on which the work cart and the transport cart are installed on the ground, and that can also run outside the track. Yes. (For example, refer to Patent Document 1.)
JP 10-338144 A

However, in the case of the technique of providing the floor 52 on the second floor as shown in FIG. 7, the facility becomes large and the floor area increases. In addition, there is a problem that the management cost increases.
Further, in the case of the technique as disclosed in Patent Document 1, when the work cart and the transport cart are operated on the floor surface of the high-rise article shelf, when working at a high place, the work is simultaneously performed below the same portion. There was a problem that workability was poor.
Also, when using a stepladder etc. that is often used simply for general high-altitude work, it is not possible to perform parallel work up and down at the same time as above, and it is difficult to achieve stability in work. There was also a safety problem.

  Therefore, the present invention simplifies the equipment configuration of the storage facility in which the high-rise article shelves are arranged to prevent the floor area from spreading unnecessarily, and enables parallel work simultaneously on the top and bottom of the same article shelf. It is intended to enable a person to work in a stable state.

  In order to achieve the above object, the present invention provides a cross beam at the same height position on the front surface or wall surface of another high-rise article shelf arranged opposite to the high-rise article shelf. In addition, the pair of horizontal beams are used as rails of the traveling body, and a person is placed on the traveling body so that the installation range of the shelf can be moved in the lateral direction by driving means.

  In this way, if a horizontal beam is provided in front of the high part of the high-rise article shelf and this horizontal beam is used as a rail for the traveling body, a person who is placed on the traveling body is required without providing a floor at the high part. You can move to a new place and work in a stable state. In addition, the floor area does not spread unnecessarily, simplifying the facility and facilitating facility management. Moreover, since parallel work can be performed simultaneously on the top and bottom of the same article shelf, work efficiency can be improved.

In the present invention, electric and manual driving are used in combination as the driving means for the traveling body.
For example, if the amount of movement is large, it is driven electrically, and if the amount of movement is small, it is driven manually, so that it is possible to reduce the labor of the operator and at the same time easily perform fine position adjustment. In addition, the apparatus configuration is simple and can be configured at low cost.
Here, as the manual drive, for example, a method of rotating the drive shaft by hand is conceivable, but specific means are arbitrary.

In the present invention, as a switch for operating the electric drive means, a hand switch operated by hand and a foot switch operated by foot are used in combination, and the traveling body moves only when both are operated simultaneously. I did it.
If the traveling body moves only by operating both of them at the same time, the traveling body will not move even if the hand switch or the foot lever is touched by mistake, which is safer.
The hand switch is preferably a mono-lever type operation switch that can change the speed in several steps by lever switching, for example.

In the present invention, a safety net is stretched below the traveling body.
Such a safety net ensures safety even when an operator unexpectedly falls from the traveling body for some reason.

By installing a horizontal beam in front of the high part of the high-rise article shelf and using this horizontal beam for the track of the traveling body, the equipment can be simplified and the floor area can be restricted, and the fire fighting equipment etc. can be controlled. Costs can be reduced. Further, since parallel work can be performed simultaneously on the upper and lower parts of the same shelf, work efficiency can be improved.
In this case, if both electric and manual driving are used as the driving means for the traveling body, it is easy to use and the apparatus can be configured simply. As the electric driving means, a hand switch operated by hand and a foot switch operated by foot When used together, safety against erroneous operation is improved. Moreover, if a safety net is stretched below the traveling body, the safety of the worker is further ensured.
