Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an interlock detecting device for an overhead traveling vehicle that facilitates construction of equipment for interlocking.

[0002]

[Prior Art]

 Equipment for interlocking is required for driving control of overhead traveling vehicles. As an interlock facility, for example, an interlock plate with a shape protruding to the side of the rail is placed at a position where interlock control of the rail is required, and a reflective photoelectric sensor or There was a type that detected the interlock plate with a proximity sensor.

[0003]

[Problems to be solved by the device]

 In the conventional method of arranging members such as interlock plates on the rails, it is necessary to firmly attach the interlock plates so that they do not come off or fall, which is troublesome and time-consuming, and the interlock plate and its mounting It required a large number of parts such as parts for use.

Therefore, an object of the present invention is to provide an interlock detection device for an overhead traveling vehicle which has a small number of members and is easy to install.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention configures an interlock detection device for an overhead traveling vehicle, which includes a magnetic tape attached to the lower surface of the rail and a magnetic sensor provided on the overhead traveling vehicle.

[0006]

[Action]

 Since the present invention has the above-mentioned configuration, it has the following effects.

According to the interlock detecting device for an overhead traveling vehicle according to the present invention, the overhead traveling vehicle traveling along the rail can be moved to the rail at a necessary position on the traveling route by the magnetic sensor provided in the overhead traveling vehicle. The interlock control is performed by detecting the magnetic tape attached to the lower surface of the.

【Example】

 The illustrated embodiment will be described below.

FIG. 1 is a plan view showing an overhead traveling vehicle to which an embodiment of an interlock detecting device for an overhead traveling vehicle according to the present invention is applied, and FIG. 2 shows an operation of the same overhead traveling vehicle in a curve. The plan view and FIGS. 3 and 4 are respectively a front view and a side view of the same overhead traveling vehicle, and some of them are shown with some members omitted.

In each figure, an overhead traveling vehicle 1 travels along a rail 2. The rail 2 has a U-shaped cross section, and the driving wheel 3 and the driven wheel 4 are in contact with the bottom surface of the inner surface of the U-shape to roll. The guide roller 5 is in contact with the folded-back portion 2 at the upper end of the U-shape of the rail 2. In the curve, the guide wheels 5 steer the drive wheels 3 and the driven wheels 4 in accordance with the curve. The drive wheels 3 and the driven wheels 4 are provided in steering units 6 and 7 which are rotatable about an axis perpendicular to the main body of the overhead traveling vehicle 1.

A magnetic tape 8 is attached to the lower surface of the rail 2 at an appropriate position. A bracket 9 is attached to the lower surface of the steering portion 6 and extends below the rail 2. A magnetic sensor 10 is attached to the tip of the bracket 9.

Next, the operation of this embodiment will be described.

When the overhead traveling vehicle 1 travels along the rail 2 and reaches the location where the magnetic tape 8 is attached, the magnetic sensor 10 detects the magnetic tape 8 and the control device for the overhead traveling vehicle 1 (shown in the figure). Notify) that it has detected. The control device receives this and controls the traveling of the overhead traveling vehicle 1.

For example, the magnetic tape 8 is attached in front of the traverser. If the traverser's moving rail is connected to rail 2, the overhead traveling vehicle can be moved to the moving rail as it is, but if the moving rail is connected to another rail, it can be moved to the ceiling. Car 1 must stop and stand by.

When the traverser side can accept the overhead traveling vehicle 1, the light source provided in the traverser is turned on, and when it cannot be accepted, the light source is turned off. The light emitted from the light source is detected by an optical sensor (not shown) provided on the front surface of the overhead traveling vehicle 1.

When the overhead traveling vehicle 1 travels and detects the magnetic tape 8, the control device determines whether the optical sensor is ON or OFF. If it is ON, the control device advances the overhead traveling vehicle 1 as it is and transfers it to the traverser. If it is OFF, the control device stops the overhead traveling vehicle, waits until the traverser side is ready, the light source is turned on, and the light sensor is turned on.

As described above, the interlock control can be performed by the combination of the magnetic tape 8 attached to an appropriate place and the magnetic sensor 10 provided on the overhead traveling vehicle side. On the side of the rail 2, all that is required is to attach the magnetic tape 8 to the lower surface of the rail 2, so there is no need for troublesome construction such as attaching an interlock plate as in the past, and the location where interlock control is performed is changed. And new installation is easy. Also, the number of members is small.

Furthermore, in the present embodiment, since the magnetic sensor 10 is attached to the steering portion 6, the magnetic sensor 10 is attached from below the rail 2 even if the rail 2 is curved. It is possible to reliably detect the magnetic tape 8 without coming off.

Although the embodiment of the present invention has been described above, it is needless to say that the present invention is not limited to the above embodiment and can be appropriately modified within the scope of the gist of the present invention.

[0020]

[Effect of the device]

 Thus, according to the interlock detection device for an overhead traveling vehicle according to the present invention, since only the magnetic tape is attached to the rail side, the construction is easy and the number of members is small, which saves manpower and cost. be able to.
