FIG. 1 is an overall view of an elevator for small parcels according to this embodiment. FIG. 2 is a top view of the luggage car showing an example of the arrangement of the inclination detectors mounted on the luggage car. FIG. 3 is a flowchart of the operation of the elevator for small parcels in this embodiment.

  Hereinafter, this embodiment will be described with reference to the drawings. In the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, the vertical / horizontal dimension ratio, and the like are appropriately changed and exaggerated from those of the actual product.

As shown in FIG. 1, a small baggage elevator 1 is connected via a luggage car 10 that moves up and down in a hoistway 2, and a rope 4 hung over the luggage car 10 by a sheave 7 and a hoisting machine 8, And a counterweight 6 that moves up and down in the hoistway 2. Further, the sheave 7 and the hoisting machine 8 are installed in a machine room 3 provided above the hoistway 2.
The hoisting machine 8 is driven and controlled by the control unit 9. Further, four inclination detectors 11 a, 11 b, 11 c, 11 d for detecting the inclination of the luggage car 10 are installed outside the luggage car 10, and when the luggage car 10 is inclined inside the luggage car 10. In order to notify the operator 20 loading the cargo 15 to that effect, a speaker 12 that emits a warning sound and a display device 13 that displays a warning are installed. The four inclination detectors 11 a, 11 b, 11 c, and 11 d, the speaker 12, and the display device 13 are all connected to the control unit 9 via the signal cable 5.
By the way, as shown in FIG. 1, the luggage car 10 is supported by a support frame 10A larger than the luggage car 10, and the four inclination detectors 11a, 11b, 11c, and 11d described above are included in the luggage 10A. It is attached to portions corresponding to the four corners of the car 10 (see FIG. 2). As described above, since the four inclination detectors 11a, 11b, 11c, and 11d are provided at the portions corresponding to the four corners of the upper surface of the luggage car 10 in the support portion 10A, the inclination of the luggage car 10 in any direction can be determined. The four inclination detectors 11a, 11b, 11c, and 11d can be detected with high accuracy.

  Next, the operation of the present embodiment having such a configuration, that is, the control method of the small baggage elevator will be described with reference to the flowchart of FIG.

  First, the worker 20 places the luggage 15 in the luggage basket 10. At this time, the worker 20 places the load so as to avoid the case that the load cage 10 is tilted by placing the load 15 in only one direction of the load basket 10 (step S1).

  The inclination detectors 11a, 11b, 11c, and 11d always detect the inclination of the luggage car 10 while the luggage 15 is being loaded and when the luggage 15 has been loaded. The detection signal from the inclination detector 11 is sent to the control unit 9.

The detection signals from the inclination detectors 11a, 11b, 11c, and 11d are always sent to the control unit 9, and the control unit 9 determines whether or not the detection signal is 10% or more that is the first inclination (step S2). ). When the detection signal is 10% or more, the control unit 9 sends a warning signal to the speaker 12, the display device 13, and the hoisting machine 8. In this case, a warning sound such as “cannot drive because it is tilted” is emitted from the speaker 12 by a warning signal from the control unit 9, and a similar warning is displayed on the display device 13. The control unit 9 keeps the hoisting machine 8 stopped. For this reason, the hoisting machine 8 does not perform the hoisting operation, so that the luggage car 10 remains stopped (step S3).

  Next, based on the warning sound from the speaker 12 and the warning display from the display device 13, the operator 20 determines that the luggage car 10 is tilted and reloads the luggage (step S4). After reloading the luggage 15, the control unit 9 determines again whether the luggage car 10 is tilted by 10% or more (step S2). In this way, it is possible to prevent the luggage car 10 from driving while being tilted.

  On the other hand, when the control unit 9 determines that the luggage car 10 is not tilted by 10% or more, the hoisting machine 8 is driven and controlled to drive the luggage car 10 up and down temporarily, and the luggage car 10 is moved up and down to the destination floor. Is started (step S5). Here, provisional driving means that the luggage car 10 is temporarily moved up and down when the luggage car 10 is not tilted by 10% or more, and when the luggage car 10 is not tilted by 5% or more as described later. This is different from the normal operation in which the luggage car 10 is moved up and down.

  During the ascending / descending to the destination floor, the control unit 9 determines whether or not the detection signal is the second slope, here 5% or more (step S6).

  When the control unit 9 determines that the inclination of the luggage car 10 is 5% or more, it controls the hoisting machine 8 to forcibly stop the luggage car 10 at the nearest floor (step S7).

  At this time, the luggage car 10 is not inclined more than the first inclination, but is inclined more than the second inclination, and there is a risk of collapse of the cargo. Therefore, after the luggage car 10 stops at the nearest floor, the worker 20 reloads the luggage 15 in the luggage car 10 (step S8). Thereafter, the control unit 9 determines again whether or not the luggage car 10 is tilted by 5% or more (step S6), and when the luggage car 10 is tilted less than 5%, a normal lifting operation is started (step S9). Thus, it is possible to more reliably prevent the luggage car 10 from driving while being tilted.

  If it transfers to a normal raising / lowering operation, it will drive | operate to the destination floor as it is (step S10). Thus, the collapse of the cargo can be suppressed by raising and lowering the luggage car 10 only when the inclination is small.

As described above, in this embodiment, the control unit 9 emits a warning sound by the speaker 12 and displays a warning by the display device 13 when the inclination of the luggage car 10 is equal to or greater than the first inclination. Can know from the warning sound from the speaker 12 and the warning display from the display device 13 that the luggage basket 10 is tilted. When the inclination of the luggage car 10 becomes less than the first inclination, the control unit 9 controls the hoisting machine 8 to temporarily move the luggage car 10 up and down, and further the inclination of the luggage car 10 becomes the first inclination. If it is less than the 2nd slope, it stops at the nearest floor. Thereafter, since the worker reloads the load again and enters the normal lifting operation, the collapse of the load can be suppressed and the normal lifting operation can be easily restored.

  Note that various modifications can be made to the above-described embodiment.
