[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a safety fence for a stacker crane used in an automated warehouse.

[0002]

[Prior art]

 Conventionally, a structure of an automatic warehouse has been known in which a stacker crane is driven to run on a transfer passage, and luggage is carried in and out from a rack arranged in a plurality of rows and stages on the side of the transfer passage. . Since the stacker crane travels on the transport passage at a high speed, it is very dangerous for an operator to enter the transport passage. Therefore, a safety fence was installed around the transport passage.

[0003]

[Problems to be solved by the device]

 The size of the safety fence that was installed as in the past varies depending on the type of stacker crane, so the length between the safety corridor and the station also varies, and the safety fence must correspond to that length. Since it was necessary to prepare many types of fences with different front and rear widths, when using a wire mesh, etc., which complicates the manufacturing process, many types of fences would have to be manufactured, resulting in higher costs and on the floor. When a pole is embedded and a fence is provided by connecting it with chains, etc., it is necessary to construct a hole in the floor to install it. Therefore, there was a demand for a safety fence that is standardized with a small number of types and has a low manufacturing cost.

[0004]

[Means for solving the problem]

 The present invention uses the following means in order to solve the above problems. That is, in the safety fence for preventing the stacker crane from entering the transportation passage in the automatic warehouse, the safety fence is composed of a lower pedestal part, an upper front opening / closing door, a fence part, and a rear end part of the fence part. It consists of a back cover that fills the gap between the station and the station.

[0005]

[Action]

 As for the safety fence, an open / close door, a fence part and a rear cover will be installed on the pedestal part to form a U-shaped fence in plan view, and the pedestal part and the fence part can be a unified standard product. By adjusting the extension length of the cover portion of the stack, the length of the transport passage or the stacker crane can be adjusted.

【Example】

 An embodiment of the configuration of the present invention will be described with reference to the accompanying drawings. Fig. 1 is an overall perspective view of the automated warehouse with the safety fence of the present invention installed, Fig. 2 is a front view of the safety fence of the present invention, Fig. 3 is the same plan view, Fig. 4 is the same side view, and Fig. 5 is safety. FIG. 6 is a plan view of the front part of the fence, FIG. 6 is a plan view of the safety fence when the rear cover is arranged laterally, and FIG. 7 is a side view of the same.

The overall configuration of the automated warehouse will be described with reference to FIG. A plurality of rows and a plurality of stages of racks R are arranged on both sides of the traveling path L of the stacker crane S to form a warehouse part. The stacker crane S is equipped with a slide fork 10, which is configured to carry a load P and move vertically and horizontally between the front mast 11F and the rear mast 11R. The crane S travels on the traveling path L, stores the load P in the desired rack R 1, or takes out the load P from the rack R. Further, in the stacker crane S, a control board 12 is arranged at the base of the front mast 11F.

The starting end of the traveling path L is configured as a station at which the stacker crane S is at a position for loading or unloading the luggage P from the loading / unloading pedestals 13/13. Has been done. A safety fence A is installed around the stacker crane S at the station position, and an operation panel C for operating the stacker crane is fixed at a predetermined position outside the safety fence A. The stacker crane can be operated by operating the operation panel C or a host computer, and the stacker crane S can be operated by an operator, and the control panel 12 can be manually operated. Has become.

Next, the structure of the safety fence A will be described. First, at the bottom of the safety fence A, a pedestal 1 is configured as shown in plan view 3. The pedestal part 1 has the operation panel pedestal 1a for mounting the operation panel C on the front right side, the step 1b for entering and exiting the fence on the front left side, and the side pedestals 1c and 1c on both sides. ing.

Further, wiring is provided between the control panel S or the stacker crane S main body and the operation panel C, and the pedestal 1 is utilized as a wiring duct for arranging the wiring H as shown in FIG. . That is, the inside of each pedestal is formed into a cylindrical shape, and the wiring H is passed from the control panel S or the stacker crane S into the pedestals 1c and 1c on both sides, the step 1b, and the operation panel pedestal 1a, and As will be described later, it is connected to an operation panel C standing on the operation panel pedestal 1a. Since the wiring can be done in this way, conventionally, the wiring was passed through a pipe and the pipe was laid on the floor surface. However, such work is unnecessary, and the wiring work is saved, and the laying work is also performed. There is no occurrence of tripping over the pipes that have been created, and the appearance is neat. Further, even when the wiring is repaired, it is known that the wiring location is inside the pedestal portion 1, which leads to speeding up of the repair.

On the pedestal portion 1 configured as described above, on the side pedestals on both sides, the wire nets 4 and 4 forming a fence are fixed, and the wire nets 4 and 4 are rearward from the rear end portion. As shown in FIG. 4, rear covers 5 and 5 are provided on the rear side of the vehicle. The rear covers 5 and 5 are for filling the gap between the rear end of the wire nets 4 and 4 and the end of the station. By attaching the rear covers 5 and 5 having a front-rear length corresponding to the width of the gap. , Cover the back of the wire nets 4 and 4. Although it is possible to make the wire nets 4 and 4 large and cut them according to the gaps, it takes time to post-process the cut portions, and the wire nets 4 are complicated in the manufacturing process, and various types of wire nets are required. Manufacturing things also leads to higher costs. Therefore, the standard standards of the wire nets 4 and 4 are kept constant, while various kinds of rear covers 5 that are simple in manufacturing process and low in cost are manufactured to reduce the width of the gap between the wire nets 4 and 4 and the warehouse portion. The gap was filled according to the difference.

A vehicle such as a forklift for loading and unloading luggage is loaded into and unloaded from the loading / unloading table 13. Therefore, it is desirable to reduce the width of the safety fence A and open the front of the loading / unloading table 13 wide. (When many automated warehouses are installed side by side, it is not possible to enter or exit from the side.) The minimum width of the safety fence A is approximately the same width as the pallet width X of the stacker crane in FIG. Up to. Therefore, if the width of the safety fence A is set to the pallet width X, the operability of the forklift to the loading / unloading platform 13 is improved, but this time the side edges of the loading / unloading platform 13 and the safety fence A are improved. There is a space between and so that people can easily enter. Therefore, it is conceivable to dispose the cover laterally so as to prevent entry into the gap between the loading / unloading table 13 and the safety fence A. However, if the cover is high, it may interfere with the stacker crane. There is a problem of causing. Therefore, as shown in FIGS. 6 and 7, rear covers 5 ′ and 5 ′, which are laterally overhanging and lower than the stacker crane S main body, are provided at the rear ends of the wire nets 4 and 4 of the safety fence A. Of. As a result, it is possible to configure a safety fence A that prevents entry into the loading / unloading platform 13 and allows a sufficient space for operating the forklift to the loading / unloading platform 13 without interfering with the stacker crane. In FIG. 6 and FIG. 7, 13 a is a station mount for mounting the carry-in / carry-out base 13.

As shown in FIGS. 2 and 5, on the front surface of the safety fence A, above the step 1b, it is possible to enter the traveling path L for the inspection of the control panel 12 and the repair of the crane. Door 2 is provided, and a plug hole 2a is formed in the door 2. When the door is closed, the outlet 7 fixed to the outlet mounting plate 9a of the left vertical frame 9 is attached to the outlet 7. The safety plug 6 can be inserted. Then, when the safety plug 6 is pulled out, the driving of the stacker crane S is stopped, and when the safety plug 6 is pulled into the door, the safety is maintained by pulling out the safety plug 6.

The door 2 is hinged to a front plate 3 fixed to a vertical frame 9 at the front of the right side wire net 4, and the operation panel pedestal 1a is projected forward at the bottom of the front plate 1c. There is. Bolt holes 1d, 1d ... Are drilled in the operation panel pedestal 1a, and a bolt hole is also drilled in the bottom of the operation panel C for stacker crane operation. The operation panel C can be integrally fixed to the front.

Various switches are attachable to the safety fence A of the present invention. Conventionally, the safety fence and the switches have been separated, and they were retrofitted or attached by hooking the cord on the wire mesh, which made the construction complicated and the appearance bad, but this solved the problem. -ing First, as shown in FIG. 5, a switch mounting hole 3a is formed in the upper portion of the front plate 3 so that an abnormal stop button, an operation mode switch, or the like can be mounted in an embedded manner. These switches are originally mounted on the crane operation panel C, but when operated on the operation panel attached to the main body of the stacker crane S, or when automatically controlled by the online method, When the operation panel C is not erected on the operation panel pedestal 1a, it must be installed at least near the safety fence A. When the operation panel C is installed upright, these switches are also incorporated, so that the switch mounting hole 3a is not necessary, and in this case, the hole is covered with a lid.

A work completion button 8 is attached to the front part of the frame bodies 4a, 4a of the wire nets 4, 4. That is, when loading a load onto the slide fork 10 of the stacker crane S, if the load is placed on the loading / unloading table 13 by a forklift or the like as shown in FIG. 1, the load is placed at the station at the start end of the traveling path L. The slide fork 10 of the stacker crane S is driven to lift the load P at that position and take it into the crane. The operation completion button 8 is pushed when the load P is completely loaded on the loading / unloading table 13 by a forklift or the like, and the slide fork 10 of the stacker crane S at the station position is moved to the above-mentioned position. It is configured to start the luggage loading drive as described above.

Conventionally, the work completion button 8 was attached to the safety fence afterwards, and the wire cord for the button was hung on the wire mesh. People and forklifts may get caught and may be dangerous. In the safety fence A of the present invention, as described above, the work completion button 8 is attached to the frame body 4a of the wire net 4, and the inside of the frame body 4a has a cylindrical shape, The code for the button can be passed through. In addition, in order to improve work efficiency, loading / unloading bases 13 and 13 are provided on both sides of the traveling path L, so that the loading / unloading bases 13 can be operated smoothly. The work completion buttons 8.8 are attached to the frame bodies 4a of the wire meshes 4 on both sides so that the buttons can be operated.
