DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tracked truck system using non-contact power supply, and more particularly to installation of a power supply cable holder and a guide rail.

[0002]

2. Description of the Related Art There is known a system in which a pair of power supply lines are arranged along a guide rail, and a high frequency is supplied to supply power to a pickup coil of a tracked vehicle in a non-contact manner. Conventionally, in such a system, the power supply line is supported by setting the holder of the power supply line on the guide rail at intervals, but there is a problem that the power supply line is exposed. Since the power supply line is exposed, the power supply line lacks aesthetic appearance, and the power supply line is likely to be caught. Further, since a large number of holders are used, workability is low.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a guide rail and a power supply line holder for non-contact power supply which are easy to construct, have high positioning accuracy with respect to a pickup coil, and have high reliability. (Claims 1 to 3). Another object of the present invention is to enhance the power supply efficiency from the power supply line to the pickup coil. An additional object of the third aspect of the present invention is to make it possible to attach the guide rail and the feed line holder at the same time, and to further facilitate the positioning between the guide rail and the feed line holder.

[0004]

According to the present invention, a guide rail and a feed line holder having a continuous shape along the longitudinal direction of the guide rail are separately provided, and these are positioned relative to each other with a pin or a key. The feed line holder is provided with a pair of continuous grooves parallel to the guide rail to hold the pair of feed lines, and by positioning the guide roller of the tracked truck with the guide rail, a pickup coil of the tracked truck is provided. In the tracked bogie system positioned with respect to the pair of power supply lines (claim 1).

Preferably, the feed line holder is formed to have a substantially U-shaped cross section, and the continuous groove is provided near both ends of the U-shaped cross section in the short side direction of the feed line holder. And the pickup coil is disposed in a U-shaped hollow portion (claim 2). Preferably, the power supply line holder and the guide rail are fixed to the mounting portion with a common fastening member such as a bolt or a nut screw. The tracked vehicle is not limited to the ground traveling type shown in the embodiment, but may be a ceiling traveling type. For example, it is assumed that a transfer device is mounted and goods are transported in a clean room or the like.

[0006]

According to the first aspect of the present invention, there is provided a guide rail made of a hard and highly accurate material such as aluminum, nylon, engineering plastic or the like, and a shape continuous along the longitudinal direction of the guide rail. And the power supply line holder are separately provided, and are positioned relative to each other using pins, keys, or the like. Since the power supply line holder is required to have a more complicated shape than the guide rail, manufacturing the power supply line holder separately from the guide rail facilitates manufacture. A pair of continuous grooves are provided in the feed line holder parallel to the guide rail to hold the pair of feed lines, and the feed lines are used to supply power to the pickup coil of the tracked vehicle in a non-contact manner. Here, if the guide roller of the tracked truck is positioned by the guide rail, the feed line holder has already been positioned with respect to the guide rail, so that the pickup coil of the tracked truck has also been positioned with respect to the feed line.

According to the first aspect of the present invention, since the power supply line holder is continuous along the longitudinal direction of the guide rail, the construction of the power supply line holder is facilitated. Further, since the power supply line is accommodated in the continuous groove of the power supply line holder, there is no possibility of a person or the like getting caught, the reliability is improved, and the appearance is increased. Furthermore, since the feeder is positioned with respect to the guide rail, and the tracked bogie is also positioned with respect to the guide rail,
The pickup coil can be positioned with respect to the power supply line.

According to the second aspect of the present invention, the cross section of the power supply line holder as viewed in the short side direction is substantially U-shaped, and the material thereof is made of insulating synthetic resin or the like. The feed line is held by providing the pair of continuous grooves at both ends, and the pickup coil is disposed in the U-shaped hollow portion. With this configuration, the pickup coil is disposed at a position sandwiched between the pair of power supply lines, and the efficiency of non-contact power supply is high. Also, even if the pickup coil is biased to the left or right with respect to the power supply line, the power supply efficiency is small since the power supply line is biased to the left or right from near the center of the pair of power supply lines. Therefore, according to the second aspect of the present invention, power can be efficiently supplied to the pickup coil from the power supply line.

According to the third aspect of the present invention, the power supply line holder and the guide rail are fixed to the mounting portion by a common fastening member. For this reason, the positioning accuracy of the power supply line holder with respect to the guide rail is further improved. Here, the attachment portion is not limited to the one provided on the floor surface or the like, and for example, a hanger suspended from the ceiling of a clean room may be used as the attachment portion.

A pair of continuous grooves 28 and 30 are provided at upper ends of both ends of the U-shape, and a litz as a power supply line is provided. The wires 32 and 34 are accommodated. The litz wires 32 and 34 are made of a number of fine wires and are stranded wires, and a high frequency of about 1 KHz to 100 KHz is passed therethrough and used for non-contact power supply. 36,38
Is a mark (dog) provided on the U-shaped bottom of the feeder line holder 16, for example.

Numeral 40 denotes a non-contact power supply section provided on the tracked truck side, which will be described later, is provided with a yoke having an E-shaped cross section using a magnetic material, and a pickup coil 44 is wound around a projecting piece 42 at the center thereof. Reference numerals 46 and 48 denote a pair of sensors for reading commands such as a stop position and a speed from the marks 36 and 38. On the tracked truck side, there are other guide rollers 50 and 52,
These are left and right guide surfaces 14, 14 of the guide rail 12.
Guides the vehicle to determine the attitude of the tracked truck.

FIG. 2 shows the construction of the guide rail 12 and the feeder holder 16.
Using the opening 4, the mounting plate 6 is mounted with bolts 8 or the like. A pair of long grooves 22 and 24 are provided at the bottom of the feeder holder 16, and the feeder holder 16 is positioned in the left-right direction with respect to the guide rail 12 by the pins 20 and the like. 66 is a pin hole on the guide rail 12 side for fitting the pin 20. U of feeder holder 16
At the center of the bottom of the character, there is a hole 60,
There is also a hole 62 communicating with the center part of the mounting plate 6 in the left-right direction, and a nut part 64 is provided at a corresponding position of the mounting plate 6. After positioning with the pin 20, the bolt 18 is inserted into the hole 6
When the feeder holder 16 and the guide rail 12 are fixed to each other through the nuts 64 through the nuts 64 and 62, the feeder line holder 16 and the guide rail 12 can be integrally attached to the attachment plate 6. And, for example, after this,
The litz wires 32, 34 are set in the continuous grooves 28, 30.

FIGS. 3 and 4 show a tracked carriage 70 on the guide rail 12. FIG. 3 shows a traveling system of the tracked bogie 70. Wheels 72 travel by a traveling motor 74, and the arrangement of the wheels 72 and the driving method of traveling are arbitrary.
The guide rollers 50 and 52 are provided, for example, in a total of four, and are arranged, for example, before and after the non-contact power supply unit 40. Further, in the guide rail 12, a hole 60 in which the bolt 18 is attached,
