Abstract

PURPOSE:To improve the safety of a sorting place by providing a photoelectric switch in such a way that a ray passage is formed through the load supporting part of a positioned bogie in the oblique up/down direction, on a guide for guiding the receiving hand bogie and a pillar erected on the terminal end of said guide. CONSTITUTION:A receiving hand bogie 4 is moved by fitting a guided pin 10 in the groove type guide rail 16 of a guide 14, a positioning column body 12 is fitted in the inlet part of the groove type guide rail 16, and a stopper 11 is brought into contact with a stopper 17. At the same time, a lock pin 13 is fitted in a lock hole to carry out positioning. In this condition, a ray passage 20 from the light emitter 21a to light receiver 21b of a load existence detecting photoelectric switch passes through the bogie 4 in the oblique up/down direction. Hence, it can be detected whether a load W is loaded on a load positioning support table 9. By this structure, a pillar which stands in the way of the side, etc., of a bogie traveling course can be eliminated, improving environment such as the safety of an operation, etc.

Detailed Description of the Invention (Industrial Application Field) The present invention relates to an automated warehouse in which a handcart for receiving cargo can be positioned at a cargo handling area of an automated warehouse, that is, beside a home position of a lane for loading and unloading. The present invention relates to a cargo presence detection device for detecting whether or not a cargo exists on the cargo receiving hand truck.

(Prior Art and its Problems) The above-mentioned cargo receiving handcart is used for the work of transporting the cargo to be stored into a fixed position at the cargo handling place, and for the work of carrying out the cargo that has been delivered to the fixed position of the cargo handling place to another location. It is used. The warehousing operation using the loading and unloading lanes begins with the transfer of the load on the cargo receiving handcart stopped at a predetermined position in the cargo handling area onto the elevating carriage of the crane using the running fork of the crane, During unloading work, the load on the elevating carriage of the crane is transferred by the running fork or the like onto the load-receiving hand truck waiting at a predetermined position in the cargo handling area.

However, during the above-mentioned warehousing work, the running fork on the crane side is activated after checking the cargo on the cargo receiving handcart using the inventory detection device, and when unloading the cargo, it is necessary to check that the cargo receiving handcart is empty. After checking with a load detection device, the running fork on the crane side must be activated, but since a freely movable hand truck is used instead of a fixed load receiving platform, a load detection device must be installed on the hand truck. I can't. Therefore, in the past, a photoelectric switch was used to form an optical path that horizontally traversed the load support section on the load receiving handcart stopped at a predetermined position in the cargo handling area.
The presence detection device was constructed by being attached to a shelf adjacent to the end of the moving path of the handcart and to a column independently erected on the floor.

In such a conventional cargo presence detection device, not only does the support for installing the photoelectric switch get in the way, making it difficult for workers to walk safely in the cargo handling area, but also the light emitting part and light receiving part of the photoelectric switch get in the way. Since the photoelectric switch is mounted on separate shelves and columns that are independent of each other, it is difficult and time-consuming to adjust the position of the photoelectric switch on site.

(Means for Solving the Problems) The present invention proposes a cargo presence detection device capable of solving the conventional problems as described above. A guide is installed to guide the trolley to a certain position, and this guide and a post erected from the end of the guide pass diagonally upward and downward through the load support part of the handcart that is positioned at a predetermined position by the guide. A photoelectric switch for detecting the presence of cargo is installed to form an optical path.

The optical path 20 leading to the vehicle passes through the truck 4 obliquely. Since the truck 4 has a framework structure as described above, the load W is placed on the load positioning support base 9.
When the truck 4 is not mounted, the light beam from the light projector 21a is input to the light receiver 21b even if the trolley 4 is locked in a fixed position as described above, and the presence detection signal is not output. However, when the load W is mounted on the cart 4, the light beam reaching the light receiver 21b is blocked by the load W, and a load presence detection signal is output.

During the warehousing operation, the cargo W to be warehoved is carried into the cargo handling area 5 by the cargo receiving handcart 4. When the trolley 4 is locked at a predetermined position in the cargo handling area 5, the limit switch 24 outputs a detection signal for detecting the fixed position of the trolley, and the light beam from the light beam 21a of the photoelectric switch for detecting the presence of cargo is blocked by the cargo W. A load detection signal is output. However, when a running fork operation OK signal is transmitted from the light emitter 26a of the photoelectric switch for transmitting and receiving signals on the ground side based on these bogie fixed position detection signals and cargo presence detection signals, the crane 3 stops at a predetermined position of the home position. Since the elevating gear range 30 is stopped at a predetermined position as described above, the light receiver 26 on the elevating gear range 30 side
b receives the running fork operation OK signal, the elevating carriage 30 and the running fork 31 operate based on this signal, and automatically perform the action of pulling the load W on the cargo receiving hand truck 4 onto the elevating carriage 30. .

(Operations and Effects of the Invention) According to the cargo handling area detection device of the present invention which can be implemented as described above, it is possible to detect whether or not there is a cargo on the cargo receiving handcart that is stopped at a predetermined position in the cargo handling area. , which can be detected by a photoelectric switch on the ground side, has a guide that guides the hand truck for receiving goods to a certain position in the cargo handling area and a column that is erected from the end of the guide to support the load of the hand truck. Since a photoelectric switch for detecting the presence of cargo is installed that forms an optical path that passes diagonally up and down through the section, there is no need to erect pillars that will get in the way of the running route of the trolley, which improves the safety of the cargo handling area. , helps improve the environment.

Moreover, since the light emitting part and the light receiving part of the photoelectric switch for detecting the presence of goods are attached to one ground frame consisting of the guide and support of the truck, the photoelectric switch can be installed in advance on the ground frame assembled in a factory, for example. The switch can be assembled in advance, compared to the case where each switch part has to be installed separately and accurately on site.
The installation of the photoelectric switch is simple and easy, and the relative positional relationship of each part of the photoelectric switch can be easily adjusted on site. Furthermore, the wiring between the photoelectric switch and the control box on the ground side can be passed through the guide frame or attached to the outside surface of the frame, making the wiring work independent of the material and condition of the floor surface. It can be easily done without.
