According to the present invention, the danger area of the automatic warehouse is surrounded by a safety fence. This safety fence has an entrance for handling luggage,
Separate outlets are provided. A primary intrusion recognition unit for detecting intrusion of a person or a foreign object, a insertion recognition unit for detecting a cargo-handling machine such as a forklift, and an insertion indicator lamp are provided in and around the insertion port. Then, when the primary intrusion recognition unit detects and activates a person or a foreign substance, it stops only the transport system for the luggage to be handled and displays the occurrence of an abnormality on the inflow indicator, and the intrusion recognition unit operates the loading / unloading machine. The signal system is constructed so that the primary intrusion recognition unit does not operate when detected and activated. In addition, a primary intrusion recognition unit for detecting intrusion of a person or a foreign substance, a removal recognition unit for detecting a cargo handling machine, and a removal indicator lamp are provided in and around the removal opening. Thus, when the primary intrusion recognition unit detects and activates a person or foreign matter, it stops only the transport system for unloading and handling luggage and displays an abnormality on the unloading indicator, and the unloading recognition unit operates When a machine is detected and activated, a signal system is constructed so that the primary intrusion recognition unit does not operate.

As described above, according to the present invention, the danger area of the automatic warehouse is surrounded by the safety fence, and the primary intrusion recognition section for detecting the intrusion of a person or a foreign substance into the entrance and the exit of the handled luggage, respectively. And that when the primary intrusion recognition unit detects a person or foreign matter, the insertion indicator light or the removal indicator lamp indicates that an abnormality has occurred, so that the person entering the danger area can be identified. Safety against entry of foreign matter can be ensured.

Further, in the present invention, a primary intrusion recognition unit for detecting intrusion of a person or a foreign object, a loading recognition unit for detecting a cargo handling machine for loading a handled baggage, and an abnormality occurrence in the vicinity of the loading port. And a primary intrusion recognition unit that detects the intrusion of a person or foreign matter, and a removal recognition that detects a cargo-handling machine to remove the handled luggage. Section and a take-out indicator light that indicates the occurrence of an abnormality, so that when the loading recognition section detects and operates the cargo handling machine, the primary intrusion recognition section provided at the loading port does not operate. In addition, when the removal recognition unit detects and operates the cargo handling machine, the signal system is constructed so that the primary intrusion recognition unit provided at the removal opening does not operate, so that the handling baggage is loaded. Mouth, outlet And when an abnormality in these neighboring occurs, the occurrence location and type accurately grasped, it is possible to deal with.

Further, according to the present invention, when the primary intrusion recognition unit provided at the insertion port detects a person or a foreign substance and operates,
Signals to stop only the transport system for incoming luggage, and to stop only the transport system for unloading luggage when the primary intrusion recognition unit provided at the outlet detects and activates a person or foreign object. Since the system is constructed, only the abnormal range can be stopped, and the rest of the facilities in the other ranges can be normally operated, while the abnormal range can be restored.

Further, according to the present invention, as described above, when an abnormality occurs in the loading / unloading port of the handled luggage and in the vicinity thereof, the location and type of occurrence can be accurately grasped. Work to take charge of the recovery process by returning only the relevant outgoing indicator light to the initial state and stopping only the relevant transport system of the incoming handled baggage transport system and the outgoing handled baggage transport system. It is possible to greatly simplify the procedure for the worker to enter the abnormality occurrence range.

In the present invention, the loading port is provided in a direction of conveyance of the handled luggage at a predetermined location of the safety fence and in a direction orthogonal thereto, and separately from the loading ports, the transfer direction of the handled luggage and the loading direction are provided. An outlet is provided in a direction perpendicular to the direction. As a result, a relatively small handled luggage within the width of the transport line is thrown in from the input port in the transport direction, and a relatively large handled luggage in the length direction of the transport line is loaded from the input port in the direction orthogonal to the transport direction. Can be easily loaded, and a relatively small unloading luggage within the width of the transfer line can be taken out from the take-out opening in the transfer direction, and the length of the transfer line can be taken out from the take-out opening perpendicular to the transfer direction. Can be easily configured to be able to take out relatively large handled luggage.

Therefore, according to the present invention, a relatively small load and a relatively large load can be rationally loaded, transported and taken out on a single transport line.

In the present invention, there is provided a comparison / judgment device for the cargo data and the handled luggage in the vicinity of the input port. The comparison / judgment device determines that the actually loaded luggage is a luggage outside the luggage data. When judged, a signal system is constructed so that the handled luggage is not transported. Therefore, the apparatus for comparing and judging the handled luggage compares the pre-registered load data with the size of the actually handled luggage and determines whether the actual handled luggage is the size in the load data. As a result of the judgment, if the actual baggage actually loaded is the size in the package data,
It is transported by the transport system for incoming handling luggage. Conversely, when the actually loaded luggage has a size outside the load data, the transport system of the loaded luggage is stopped so as not to be transported.

Thus, according to the present invention, even if a nonstandard package is mistakenly loaded in the handled baggage, the baggage can be automatically detected at the loading stage and the operator can remove it. It is possible to prevent various troubles caused by carrying nonstandard handling luggage to the entrance.

Further, in the present invention, a loading section conveyor is installed inside the loading port, and a device for detecting the package appearance of the handled luggage is provided within the transport range of the loading section conveyor. Then, when the packing state detection device detects an abnormal packing state of the handled luggage placed on the loading unit conveyor, the packing state detecting apparatus is configured not to transport the handled luggage and to display an occurrence of the abnormality on the loading indicator. We are building a signal system. Therefore, the handled luggage is thrown into the loading section conveyor and placed thereon, and the form of the handled luggage, that is, the height of the handled luggage, the load protruding, and the like are inspected by the packing form detecting device. As a result of the inspection, when there is no abnormality in the package, the package is delivered from the loading section conveyor to another transport device and transported in the direction of the entrance. Conversely, when an abnormality in the form of the load, such as the height of the load or the protrusion of the load, is detected, the handled luggage is not conveyed, and the occurrence of the abnormality is displayed on the loading indicator.

Therefore, according to the present invention, when an abnormality such as a load height or an unloading of a loaded baggage occurs, it can be automatically detected at the stage of loading the baggage. Load collapse can be prevented beforehand.

Further, in the present invention, a loading section conveyor is provided inside the loading port, and a loading section conveyor is connected to the loading section conveyor on the unloading side, and a package shape detection is performed between the loading section conveyor and the loading section conveyor. Equipment is deployed. Thus, when the packing state detecting device detects a packing state abnormality, the baggage is returned to the loading position, an occurrence indicator is displayed on the loading indicator lamp, and the packing state detecting device is corrected. A signal system is configured to function as a secondary intrusion recognition unit when a worker enters the loading unit conveyor from the loading unit conveyor. That is, in the present invention, the handled luggage is loaded onto the loading section conveyor, placed and transported once in the direction of the loading section conveyor. Next, it is inspected by the packing state detecting device whether the handled luggage on the input section conveyor has a load height or a load protruding or not. As a result of the inspection, when there is no abnormality in the package, the handled luggage is delivered from the loading section conveyor to the loading section conveyor, and is conveyed to the loading port by the loading section conveyor.
As a result of the inspection, if an abnormality in the package is detected, the baggage handled is returned to the loading position by the loading section conveyor, a work space for correcting the package is secured on the loading section side of the loading section conveyor, and a loading indicator light Is displayed, and the package appearance detecting device is further operated as a secondary intrusion recognition unit. Therefore, when an abnormality is detected in the package, the worker enters the work space secured on the carry-out side of the input unit conveyor and corrects the package. During such package modification work,
If a worker inadvertently tries to enter the loading section conveyor from the loading section conveyor, the packing state detection device functions as a secondary intrusion recognition section, and the occurrence of an abnormality is displayed on the loading indicator lamp to call attention.

Therefore, according to the present invention, it is possible to detect an abnormality of the package at the stage of loading the handled luggage, and when the abnormality of the package is detected, a work space for a worker who performs a work to correct the package of the handled luggage is secured. Correction work can be performed carefully, and the safety of the correction worker can be ensured.

In the present invention, a loading operation panel is provided near the loading port, and a loading completion button, a return button, and a key are inserted into the loading operation panel to selectively switch the mode between the operation enabled and stopped modes. A possible key switch and a restart button are provided. Then, after loading the handled luggage through the loading port onto the loading section conveyor, the operator presses the loading completion button. When the loading completion button is pressed, the loading section conveyor and the loading section conveyor rotate forward, and the handled baggage is transported toward the loading section conveyor. As mentioned above,
When the handled luggage is conveyed to the unloading unit side of the loading section conveyor, the package is inspected by a package detection device. As a result of the inspection, when there is no abnormality in the package, the handled luggage is delivered from the loading section conveyor to the loading section conveyor, and is conveyed to the entrance by the loading section conveyor. As a result of the inspection, when an abnormality in the package is detected, the occurrence of the abnormality is displayed on the loading indicator and the loading section conveyor and the loading section conveyor are stopped. Here, when the operator presses the return button, the indication of the occurrence of the abnormality of the loading indicator is released and the initial state is returned, the loading section conveyor and the loading section conveyor are rotated in the reverse direction, and the handled luggage is returned to the loading position.
At this time, a work space for correcting the package is secured in the loading section conveyor, and the package detection device detects the occurrence of abnormalities when the correction worker enters the loading section conveyor from the loading section conveyor. Set to work as a part. Before starting the packing correction work, the worker switches the key that has been inserted into the key switch and set in the operable mode from the operable mode to the stop mode, and then pulls out the key switch, and the worker removes the key from the key switch. With the key in hand, enter the work space secured on the carry-out side of the loading section conveyor, and carry out work to correct the package. As mentioned above, since the package change operator switches the key switch to the stop mode and possesses the key, a third-party erroneously operates during the package change work, such as the loading unit conveyor or the loading unit conveyor. It is possible to completely prevent a malfunction of the equipment on the side of the input section of the apparatus.
Also, if the worker inadvertently enters the conveyor of the loading section from the loading section conveyor during the modification of the packing state, the packing state detecting device, which is the secondary intrusion recognition section, operates, and the occurrence indicator is displayed to indicate the occurrence of abnormality, Call attention. When the worker inserts the key into the key switch after changing the packing state and switches the mode from stop to operable mode, the equipment at the loading section including the loading section conveyor, loading section conveyor, loading indicator, and package detection device Is returned to the initial state. In this state, when the restart button is pressed, the loading section conveyor and the loading section conveyor rotate forward again, and the handled luggage whose packaging has been corrected is delivered from the loading section conveyor to the loading section conveyor, and is loaded by the loading section conveyor. Conveyed to the mouth.

As described above, according to the present invention, the closing button, the return button, the key switch for switching between the operation enable and stop modes with the key inserted, and the restart button provided on the closing operation panel are provided for safe operation. By operating according to the specifications, it is possible to ensure the safety of the package modification worker.In particular, switch the mode from operable to stop mode with the key inserted into the key switch, and the worker pulls out the key By possessing, it is possible to completely prevent malfunction of the equipment on the loading section side due to erroneous operation by a third party during the work of correcting the package appearance, and it is possible to more surely assure the safety of the worker who has recovered from the abnormal state.
