Figure 8 User manual for a complete diagnosis.

[0048] The power supply unit 10 is configured to enable the lamp 12 to light up when powered on, but when the lamp is turned off, the input power and the fuse need to be checked.

[0049] In addition, the rocker switch unit 20 is configured to turn on the light 22 when the rocker switch set on the surface of each layer is turned on, and the transport vehicle arrival limit unit 30 is configured to detect when the transport vehicle reaches the selected layer and turn on the light 32.

[0050] At this time, if Figure 3 As shown, in the case of a three-layer structure, the rocker switch unit 20 and the transport vehicle reaching limit unit 30 are arranged on the first layer, the second layer and the third layer, as shown in FIG. Figure 4 As shown, in the case of a two-layer structure, it is arranged on the first layer and the second layer.

[0051] Furthermore, the transport vehicle operating condition section 40 is configured to allow the lights 42a, 42b, 42c, 42d, and 42e connected to the functional sections to light up when the emergency limit sections arranged at the uppermost and lowermost layers to detect that the transport vehicle is detached are operated, when the door limit sections arranged at each layer between the uppermost and lowermost layers are opened, when the drive motor driving the transport vehicle to lift and lower is overloaded, and when used for lighting up one or more of the emergency limit sections, door limit sections, and drive motor overloads.

[0052] At this time, if Figure 3 As shown, in the door stopper, in the case of a three-layer structure, the door stoppers of the first layer, the second layer and the third layer are connected to the lamps of each door stopper, such as Figure 4 As shown, in the case of a two-layer structure, the door stoppers of the first layer and the second layer are connected to the lamps of the door stoppers.

[0053] The transport vehicle operation status unit 50 is configured as follows: when the buzzer 55 and the rising and falling arrows of each layer are operated, the lights 52a, 52b, and 52c are lit, wherein the buzzer 55 performs a reminder operation for a certain period of time when the transport vehicle arrives at the locker of the selected layer, and the rising and falling arrows 56a, 56b of each layer are lit during the rising or descending operation of the transport vehicle.

[0054] In addition, the connector 200 of the printed circuit board is configured as follows: a connecting terminal 220 is provided on the inner side of an insertion slot 210 for horizontally inserting the wires 2 of each functional part, and a clamping bolt 230 is threadedly coupled to the vertical upper portion of the connecting terminal. The clamping bolt 230 is used to clamp the wires 2 of each functional part inserted into the connecting terminal, so as to simply and firmly clamp the wires of each functional part.

[0055] As a reference numeral not described, 300 denotes a distribution box.

[0056] Next, a fault diagnosis method of a printed circuit board using the present invention constructed as described above will be described with reference to the accompanying drawings.

[0057] The article transport elevator of the present invention supplies articles by opening and closing the door of the locker reached by the transport vehicle after the articles are loaded onto the transport vehicle and ascend or descend to the locker position of the selected layer, and when the transport vehicle reaches the selected layer, the buzzer light operates for a set time, so that the operator recognizes that the articles have arrived and receives the articles through the opening and closing operation of the door.

[0058] In the present invention, the printed circuit board 100 is built into the distribution board 300, so that the operator can view and inspect the printed circuit board 100 of the distribution board, and by confirming whether the lights of the printed circuit boards that are connected to the power supply part of the article transport elevator, the rocker switch parts of each floor, the transport vehicle arrival limit part, the transport vehicle operating condition part and the transport vehicle operation status part are on, even non-professionals can perform comprehensive, simple and rapid diagnosis.

[0059] More specifically, the operator Figure 8 The operator manual in the PCB confirms whether the lamp 12 of the printed circuit board is on, to confirm and check whether the power supply unit 10 is powered and whether it is operating normally. At this time, if the lamp is in the off state, the input power supply and fuse failure are diagnosed.

[0060] Furthermore, by confirming whether the lamp 22 of the printed circuit board is on, it is confirmed and checked whether the rocker switch 20 provided on each layer of the surface board is operating normally.

[0061] In addition, by confirming whether the light 32 of the printed circuit board is on, it is confirmed whether the transport vehicle arrival limiting unit 30 for detecting whether the transport vehicle has arrived at the selected layer is operating normally.

[0062] At this time, if the light 32 is not on, it can be confirmed that the transport vehicle arrival limit part 30 has a fault or is not set in the correct position and has left the setting position and cannot operate normally, so the transport vehicle arrival limit part can be inspected and repaired.

[0063] In addition, by confirming whether the lights 42a, 42b, 42c, 42d, and 42e of the printed circuit board are on, not only the operation of the emergency limit parts arranged at the uppermost and lowermost layers, the opening operation of the door limit parts arranged at each layer between the uppermost and lowermost layers, and the overload of the driving motor that drives the transport vehicle to rise and fall can be checked, but also it can be confirmed and checked whether the functions in use are operating normally due to the lighting of more than one of the emergency limit parts, door limit parts, and overload of the driving motor.

[0064] At this time, the emergency limit parts of the uppermost and lowermost layers are normally B contacts, which light up when operated, the door limit part is normally A contact, which lights up when opened, the motor overload is normally B contact, which lights up when overloaded, and when any one of the emergency limit part, door limit part and motor overload lights is lit and used, the light in use also lights up at the same time.

[0065] In addition, by confirming whether the lights 52a, 52b, and 52c of the printed circuit board are on, it is possible to confirm and check whether the buzzer 55 and the rising and falling arrows 56a and 56b of each layer are operating normally, wherein the GIA buzzer 55 performs a reminder operation for a certain period of time when the transport vehicle arrives at the locker of the selected layer, and the rising and falling arrows 56a and 56b of each layer are lit during the rising or descending operation of the transport vehicle.

[0066] Therefore, by confirming the lighting status of the lights on the printed circuit board 100 installed on the distribution board, the present invention allows even non-professionals to comprehensively, simply and quickly diagnose whether the functional parts of the elevator are operating normally, that is, whether the functional parts are faulty, and take measures.

[0067] In addition, the printed circuit board 100 of the present invention can be mainly used to diagnose faults occurring during the operation of the goods transport elevator. It can also confirm whether the light of the printed circuit board is on during the installation and construction of the goods transport elevator. It can also confirm whether the power supply unit 10, the rocker switch unit 20 of each layer, the transport vehicle arrival limit unit 30, the transport vehicle operating condition unit 40 and the transport vehicle operation status unit 50 have been installed normally, thereby making the initial installation and setting easier and faster.
