Description

  The present invention relates to a transport system, and more particularly to a transport system that transports a package after it has been transported.

  A conventional automatic warehouse includes, for example, a pair of racks, a stacker crane, a warehouse station, and a warehouse station. The pair of racks are provided at a predetermined interval in the front-rear direction. The stacker crane is provided so as to be movable in the left-right direction between the front and rear racks. The warehousing station is arranged on the side of one rack. The delivery station is arranged on the side of the other rack. The rack has a number of shelves on the top, bottom, left and right. The stacker crane has a traveling carriage, a lifting platform that can be raised and lowered on a mast provided therein, and a transfer device (for example, a slide fork that is slidable in the front-rear direction). ing.

  Once the load is placed at the storage station, the stacker crane then takes the load and transports it to the intended shelf.

As described above, when the stacker crane takes in the load from the storage station, specifically, the transfer device transfers the load to the top of the lift platform. In that case, the load placed on the lifting platform may cause a load appearance abnormality (including load slippage and collapse) after a lapse of time after placement. A stacker crane has been proposed as a means for coping with this cargo appearance abnormality problem to accurately grasp the situation of the cargo appearance abnormality and quickly recover it (see Patent Document 1).
The stacker crane described in Patent Literature 1 includes a camera 7 that captures an image of the load L placed on the lifting platform 4 and a controller 10. Based on the image captured by the camera 7, the controller 10 compares the positional relationship between the load L and a reference region on which the load is to be placed, and the comparison result by the comparison unit. In addition, when the load L protrudes from the reference region, an output unit that emphasizes the portion of the load protruding from the reference region and outputs an image to the display device is provided.

(6) Control Operation In the stacker crane 3 configured as described above, the camera 71 continues to image the state on the lifting platform 27 during the automatic operation of the stacker crane 3. Specifically, imaging is performed when a load is received by the elevator 27, and the data is stored in the first storage unit 57A. Thereafter, imaging is performed regularly or irregularly, and the image data is stored in the storage unit 57. Image data relating to one package is associated with each other, and package information, date / time information, and status information are given to each image data as necessary.
It should be noted that the time when the package is received by the elevator 27 means that a short period of time has passed immediately after it has been received or has been received.

  Then, if a load state abnormality is detected by a signal from the load state sensor 75, the image server 51 stores the image data captured at that time or slightly later in the second storage unit 57B. Furthermore, the image server 51 notifies the operator of an abnormal state using an alarm (not shown). It should be noted that the imaging and data storage of the abnormal packaging are not necessarily performed.

  If a load appearance abnormality is detected, the main controller 53 stops the automatic operation of the stacker crane 3. Specifically, the main controller 53 causes the travel control unit 54 to stop traveling, causes the elevating control unit 55 to stop elevating, and causes the transfer control unit 56 to prevent the slide fork 29 from moving back and forth with respect to the shelf 13. To interlock. When the stacker crane 3 can be forcibly operated, the operator moves the stacker crane 3 to a place where it is easy to work by remote control. Then, the state of the load W causing the load appearance abnormality is repaired by the operator, and then the interlock of the stacker crane 3 is released. On the other hand, when the stacker crane 3 cannot be forcibly operated, the state of the load W causing the load appearance abnormality is repaired by the operator, and the stacker crane 3 can be forcibly operated. Then, the state of the load W causing the load appearance abnormality is repaired by the operator, and then the interlock of the stacker crane 3 is released.

  After recovery, the operator uses the input device 72 to search the PC 52 for image data at the time of receipt of the parcel for the parcel W with the parcel abnormality detected, in order to know the cause of the parcel abnormality. To do. Accordingly, the display control unit 58 reads the data from the first storage unit 57A of the storage unit 57, and then displays the data on the display 73. As a result, as shown in FIG. 6, the baggage imaging data at the time of acceptance is displayed on the display 73. As is apparent from the figure, the load W does not cause a load appearance abnormality at this point, but shows an inappropriate stacking condition that will cause a future load appearance abnormality. As described above, the baggage imaging data at the time of receiving the baggage W in which the load appearance abnormality is detected is read from the storage unit 57 and displayed on the display 73. Therefore, the operator can confirm how to load the load causing the load appearance abnormality. As a result of the above, the operator can learn how to place a load and cause a problem. As a result, the way of loading the load causing the load appearance abnormality is improved.

The camera 71 takes a picture of the load when the load sensor 75 detects the load W abnormality of the load W, and the storage unit 57 (specifically, the second storage unit 57B) The package image data of the state is saved.
Therefore, the display control unit 58 can read the baggage imaging data in the abnormal state of the package from the storage unit 57 and display it together with the baggage imaging data when the baggage in the abnormal state of the package is received. For example, as shown in FIG. 7, the baggage imaging data at the time of acceptance and the baggage imaging data in the abnormal state of the cargo appearance are displayed on the display 73.

  In this way, since the baggage imaging data in the abnormal state of the packing state is displayed in association with the baggage imaging data at the time of accepting the baggage in the abnormal state of the packing state, the operator can compare the cause and the result of the abnormal state of the packing state, Learn more about how to load packages that cause abnormal packaging. In this embodiment, two types of imaging data are simultaneously displayed on one screen, but may be displayed by switching what is on another screen.

  The storage unit 57 (specifically, the third storage unit 57C) also stores the baggage imaging data in the normal state of the package. Then, the display control unit 58 reads the baggage imaging data in the normal state of the package from the storage unit 57 and displays it together with the baggage imaging data at the time of receiving the package W in the abnormal state of the package. For example, as shown in FIG. 8, the baggage imaging data at the time of acceptance and the baggage imaging data in the normal state of the package are displayed on the display 73. In this embodiment, two types of imaging data are simultaneously displayed on one screen, but may be displayed by switching what is on another screen.
