[Purpose of invention]

[Technical field to which the invention belongs and the prior art in that field]

TECHNICAL FIELD The present invention relates to a rail device for conveying equipment, for example, used in a suspension conveying facility for conveying a vehicle body on a fixed path on the ceiling side in an automobile assembly plant.

Conventionally, in this kind of rail apparatus, as the connection structure between the end portions of the rail, for example, the configuration disclosed in Japanese Patent Application Laid-Open No. 53-115586 is provided. That is, a power line rail made of I-shaped material and a pair of left and right free line rails formed of C-shaped material and whose openings thereof face each other are disposed, and these rails are provided by intermediate-joining yokes every predetermined time. In addition to being connected, it is connected by the connecting yoke at both ends.

Here, the connecting yoke is formed by bending and extending the elongated portion which is integrally connected and provided inside the lower end portions of both ends thereof. In the state where the back side of the free line rail is in contact with the inner surface of the elongated part, welding is performed by using the edge of the elongated part, and the outer surface of the connecting yoke and the rail end of the free line rail have one surface. Both sides are connected. The rail for the power line and the connecting yoke are similarly connected using a reinforcing rib plate or the like.

The connection between the ends of the rails in the longitudinal direction is performed by acting a coupling tool consisting of bolt nuts between the connecting through holes which are connected to each other while the outer surfaces of both connecting yokes are connected.

However, according to the conventional connection structure between the rail end portions, two types of yokes are required, i.e., connection yokes having an elongated portion and intermediate yoke for intermediate portions not having an elongated portion. The production of the melted oak becomes difficult, and a dedicated device for bending and bending the elongated portion is required. In addition, the welding using the edge of the elongated portion has welding along the rail length direction, and furthermore, since the length of the welding line is long, new welding is applied to the whole welding.

In addition, when connecting the outer surfaces of the connecting yokes in contact with each other in the longitudinal direction of the rails, both connecting yokes are changed by welding misalignment or the like, so that the connection accuracy between the rails is rarely obtained as desired. On the other hand, although a misalignment is performed, it takes time to catch this misalignment.

Moreover, conventionally, in this kind of rail apparatus, as a connection structure between upper and lower rails, the structure shown by Unexamined-Japanese-Patent No. 58-44044 is provided, for example. That is, a power rail made of I-shaped material and a pair of free rails facing each other with its open portion made of C-shaped material are disposed, and these rails are connected by a connecting frame at every desired time.

However, according to the conventional connection structure between the upper and lower rails, the rail is connected to the connecting frame by welding, and welding is not easily performed while increasing the accuracy between the rails.

The free rotation is comprised by the rollers 55 etc. which were provided freely, and these rollers 55 hold | maintain and guide to the upper surface in the lower plate part of the said upper rail 11. In addition, the link chain 51 is linked to a drive unit (not shown in a motor or the like).

The operation in the first embodiment described above will be described below.

The middle yoke material 20 and the end yoke material 21 which connect the 1st rail 11 and the 2nd rail 15 are formed in the same shape, and are formed in the shape of a flat plate of a door shape, and are located in a predetermined position. The connecting holes 22 and 23 are formed, respectively.

And before assembling the rail apparatus 10, the 1st rail 11 and the 2nd rail 15 are connected through the middle part yoke material 20 and the end part yoke material 21. As shown in FIG. That is, in each intermediate | middle rail part 20, the lower edge of the intermediate part is double-sided welded 12 to the upper surface 11a of the 1st rail 11 in the upper board part, and the inner inner edge of the lower part in both side board parts. Is double-sided weld 16 to the outer surface 15a of the second rail 15, thereby connecting the rails 11 and 15 together.

In the end rail member 21, the welding edge L is positioned inward from the rail end surfaces 11b and 15b of the respective rails 11 and 15, and the lower edge of the center portion of the upper plate portion is first. The upper end 11a of the rail 11 is fixed to the rail end by double-sided welding 13A, 13B using this welding table L, and the lower inner edge of the lower side of the second rail 15 The outer surface 15a is fixed to the rail ends by double-sided welding 17A and 17B using the welding table L, thereby connecting the rails 11 and 15 to each other.

One of the split rail apparatuses formed in this way is connected to the brancat 5 on the ceiling structure side through a connector 6 which penetrates through the upper connector hole 22 of the intermediate yoke material 20. It is hypothesized on the ceiling side. Another split rail device is rail-connected to the split rail device constructed in this way. That is, immediately before the rail connection and when the connection by the double-sided welding 13A, 13B, 17A, 17B between each rail 111, 15 mentioned above is performed, At a predetermined position on the outer surface, the handle metal plate 24 is fixed by welding (used welding etc.) 25, respectively.

The rail connection is performed using the end yoke material 21. In the state in which the rail end faces 11b and 15b of each rail 11 and 15 face each other in the longitudinal direction of the rail, the end yoke material (21) is connected via a connector (26) inserted between the holes (22, 22), (23, 23) for the connector. This inserts the bolt 27 into the connector holes 22 and 23, the handle metal plates 24 and 24, and the connector holes 22 and 23, and then inserts the washer 29 outward at the protruding end thereof. The nut 28 can be screwed in and fastened.

At that time, since the handle metal plate 24 of a long shape is fixed to the surface which becomes the outer side of the end part oak material 21 by the thickness which buried the above-mentioned welding stand L, it is just by the connector 26 The tightening force acts between the handle metal plates 24 connected to each other, that is, the rail ends 11b and 11b and 15b and 15b connected to each of the rails 11 and 15 are easily twisted. Since the end yoke member 21 is not acted on, the rail connection can be easily and quickly performed with high accuracy through the end yoke member 21 and the connector 26.

At that time, the grip metal plate 24 of the long shape is fixed to the surface which becomes the outside of the end of the end portion oak material 21 with the above-described welding rod L, and is tight by the connector 26. The tightening force acts between the handle metal plates 24 which are in contact with each other, that is, between the end faces 11b, 11b and 15b and 15b of the rails 11 and 15 which are in contact with each other, and are easily displaced. It is prevented from acting between the auxiliary yoke materials 21, so that the rail connection via the end yoke material 21 and the connector 26 can be easily and quickly performed with high accuracy.

At the time of the operation which completed the desired assembly of the rail apparatus 10, the assembly of the conveying apparatus 30, etc., the movement of the trolley apparatus 31 engages the rolling element 56 with the passive body 40. This is performed on a certain path by receiving the moving force of the driving body 50. At this time, the front end side of the operation lever 42 moves downward. When the trolling device 31 which is moving in this way attempts to runaway, the runaway blocking member 43 comes into contact with the rear face of the rolling element 56, whereby the runaway is prevented.

In operation as described above, the trolley device 31 is guided by holding the guide foil 38 fitted to the second rail 15, and the anti-foil foil 39 is provided with the second rail ( It is located on the end face of the lower plate part of 15) and guided, and it stably moves on a certain path without large shaking. Moreover, the roller 55 is guided by the 1st rail 11, and the drive body 50 moves smoothly.

Next, a second embodiment will be described with reference to FIGS. 5 and 6.
