Description

Detailed Description of the Invention "Field of Industrial Application" The present invention is applicable to various utilities used in production conveyor lines in factories, such as hand lighting, vacuum exhaust lines, compressed air lines, and power supply lines. Concerning the structure of arranging lines within a factory.

"Conventional technology" In factories that use conveyor lines to manufacture products through assembly lines, there are lines (utility lines) that supply utilities such as power, lighting, and compressed air necessary for manufacturing products along the conveyor lines. A tailoring line) has been installed.

FIG. 3 is a sectional view showing the arrangement structure of a conventional utility line for a production conveyor line.

Reference numeral 1 in the figure is a conveyor line installed on the floor A in the factory and extending in a direction perpendicular to the drawing. This conveyor line 1 includes a pair of belt conveyors 2, 2, and these belt conveyors 2, 2 are adapted to transport articles in the order of processes.

At the center of the upper surface of the conveyor line 1, a utility line support frame 3 is disposed along the line 1. This frame 3 includes pillars 4 erected at regular intervals along the line 1,
A roof member 5 fixed to the upper end of these pillars 4...
It consists of. A power line 6, a compressed air line 7, etc. are arranged in the middle of the pillars 4. Further, the roof member 5 is provided with lighting devices 8, 8 for illuminating the top of each belt conveyor 2, 2, a vacuum exhaust line 9, and the like. In this case, the power supply line 6, compressed air line 7, lighting device 8, and exhaust line 9 are utility lines.

``Problems to be Solved by Inventions'' Recently, as consumer needs have become more diversified, there has been a growing trend in various manufacturing plants to produce a wide variety of products in small numbers.

As a result, manufactured items are frequently changed within a short period of time, and in a factory using a conveyor line, the conveyor line must be rearranged each time.

In such a case, in the conventional utility line arrangement structure, since the utility lines 6, 7, 8, and 9 are fixed on the conveyor line 1 by the support frame 3, First, all the utility lines 6, 7, 8, 9 are separated from the supply source, and along with the conveyor line 1, the support frame 2 and the utility lines 6, 7,
It is necessary to move the lines 8, 9 and then connect the lines 6, 7, 8, 9 to the source again. Therefore, there were problems in that it took time and effort to relocate the conveyor line 1, and that it was difficult to respond quickly to changes in manufactured items, and at the same time, it was expensive.

In addition, in the above-mentioned arrangement structure, since a large number of columns 4 of the utility line support member 3 stand on the conveyor line 1, these columns 4 obstruct the worker's view and make it difficult to see inside the factory. bad. Therefore, it is difficult to manage the conveyor line 1.
Improvements were also desired in terms of safety.

"Means for Solving the Problems" The present invention provides a utility system that is arranged approximately parallel to the extending direction of the conveyor line and supplies electricity, compressed air, etc. to work performed on a production conveyor line in a factory. In the arrangement structure of the utility line, a supporting member that collectively holds the utility line is suspended and supported from the ceiling so as to be movable horizontally in a direction substantially perpendicular to the direction in which the conveyor line extends. Features.

"Example" Hereinafter, an example of the present invention will be described in detail using the drawings.

FIG. 1 is a sectional view of the utility line arrangement structure of this embodiment, and reference numeral 1 in the figure indicates a conveyor line. This conveyor line 1 is located on the factory floor A.
It is equipped with belt conveyors 2, 2 for transporting products.

A plurality of guide rails 10 are laid in parallel to each other on a ceiling surface B above the conveyor line 1 in a direction perpendicular to the direction in which the conveyor line 1 extends (the front and back directions of the drawing in FIG. 1). These guide rails 10 are supported by a plurality of supports 11...
It is installed with a certain distance from the ceiling surface B. A rectangular cylindrical utility line support frame (supporting material) 12 is suspended and supported on these guide rails 10 in parallel to the conveyor line 1 at a predetermined distance above the conveyor line 1. Therefore, unlike the conventional conveyor line, there are no supports or the like on the upper surface of the conveyor line 1.

Wheels 13 are mounted on the upper surface of the support frame 12.
A plurality of pairs of suspension devices 13 are attached. The support frame 12 is suspended by hooking a pair of wheels 13a onto each guide rail 10, and the wheels 13a roll along the guide rail 10 by rolling on the upper surface of the guide rail 10. It is considered movable.

Inside the support frame 12, utility lines such as a power supply line 6, a compressed air line 7, an exhaust line 9, and the like are collectively housed and held. These utility lines 6, 7, 8, 9
are arranged parallel to the direction in which the conveyor line 1 extends. Furthermore, lighting devices 8, 8 for illuminating the top of the belt conveyors 2, 2 are attached to both sides of the outer bottom surface of the support frame 12.

The ends of the utility lines 6, 7, 8, and 9 on the supply source side are flexible cables (not shown) that can be bent freely. Further, the length of these end portions is set to be sufficient for the support frame 12 to move over the entire length of the guide rail 10. These utility lines 6, 7, 8, and 9 are adapted to appropriately supply utility to the outside through holes (not shown) formed in the frame 12. In the figure, P and Q are tools that are supplied with such utilities.

A plurality of moving wires 14 extending in the horizontal direction are connected to the upper portions of both sides of the support frame 12. These moving wires 14...
are stretched as shown in FIG. 2 to constitute a frame moving mechanism.

Each wire 14 is bent by a pulley 15 installed on the ceiling surface B, and wires connected to the same side of the frame 12 are bundled together. The ends of the wires 14 on the right side of the figure are wound around a winding device 16R, and the ends of the wires 14 on the left side are wound around a winding device 16L.

Therefore, when the wires 14 are wound by one of the winding devices 16R, each wire 14 connected to the right side of the frame 12 moves to the right by the same length, and the support frame 12 moves as a guide. The guide rail 10 remains oriented perpendicularly to the rail 10.
... will be moved along. At this time, as the frame 12 moves, from the other winding device 16L,
The wires 14... are pulled out one after another. When moving in the opposite direction, the other winding device 16L is operated in the same manner.

According to the utility line arrangement structure having such a configuration, each of the utility lines 6, 7,
8, 9 are movably suspended and supported along a guide rail 10 extending in a direction perpendicular to the conveyor line 1, each utility line 6, 7,
8 and 9 can be easily rearranged in a direction perpendicular to the conveyor line 1 (width direction of the conveyor line 1). Therefore, it becomes necessary to relocate the conveyor line 1 to one of the width directions, that is, to the side, and accordingly, the utility line 6,
When moving lines 7, 8, and 9, it is possible to eliminate the trouble of disconnecting them from their supply sources and reconnecting them, and compared to conventional structures, the time and cost required for line relocation can be significantly reduced. It is possible to reduce this.

In addition, in this arrangement structure, the utility lines 6, 7, 8, and 9 are suspended from the ceiling, away from the conveyor line 1, so there is nothing on the conveyor line 1 that obstructs the view, and inside the factory. The outlook will improve. Therefore, it has advantages such as easier manufacturing control and increased safety.

Also, utility lines 6, 7, 8, 9
are housed and held together in the support frame 12, so the utility lines 6, 7,
8 and 9 themselves do not obstruct movement and move smoothly.

Furthermore, in this arrangement structure, the winding device 16R,
Since the wires 14 are moved by the winding devices 16L, which move the frame 12, the winding devices 16R and 16L can be moved even when the frame 12 is at a high position that is out of reach. The frame 12 can be moved extremely easily just by operating it. Note that it is also easy to automatically perform this movement using an electric motor.

Alternatively, a plurality of support frames may be suspended and supported on the same guide rail, and any one of them may be moved onto the conveyor line to select the utility.

"Effects of the Invention" The utility line arrangement structure for a production conveyor line of the present invention has the following excellent effects.

A supporting material is provided to collectively support the various utility lines, and this supporting material is suspended so that it can move horizontally in a direction perpendicular to the direction in which the conveyor line extends, so that the utility line can be connected to the conveyor line. It can also be moved horizontally to any desired position, and there is no need to disconnect or reconnect each utility line from its supply source when relocating the conveyor line. Therefore, it is extremely easy to change the line arrangement, and the time and cost required for line relocation can be significantly reduced.

By suspending and supporting the utility line from the ceiling, it is separated from the conveyor line, so there is nothing blocking the view on the conveyor line, and the visibility inside the factory is improved. Therefore, production management is easy and safety is improved.

Since the utility line is collectively held by the supporting material, the utility line itself does not become an obstacle to movement and moves smoothly.
