DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling conveying device used for conveying a package formed by winding a yarn around a bobbin.

[0002]

2. Description of the Related Art Conventionally, a package formed by winding a yarn spun from a spinning machine onto a bobbin by a high-speed winding device is a ceiling conveying device that circulates in a factory for the purpose of protecting a yarn layer and saving space. And was transported to the unloading station and stocker.

[0003] In such a ceiling transport device, an L-shaped hanger whose end is bent in a traveling direction is provided to a carrier which is pulled and moved by an endless chain along a rail, and is hung down. The tip of the bent hanger is inserted into the bobbin of the package to suspend and transport the package, but the package support of the hanger is almost horizontally in consideration of the workability when inserting and removing the package. Since the package is provided to support the package in the forward direction, if there is a downhill portion in the transport path, the support portion is lowered forward, and the package may fall out.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional overhead conveying apparatus, and it has been found that the package can be prevented from falling off on a downhill portion of the conveying path and the supporting state can be stabilized. It is an object of the present invention to provide a ceiling transport device that is not in use.

In the downwardly inclined portion of the transport path, the moving body descends forward along the rail, but the package supporting member is in the first position consisting of the guide roller and the guide rail.
By the control means, the conveying posture is rotated relative to the moving body so that the conveying posture is maintained in a horizontal or predetermined reverse forward leaning posture .
In the horizontal or upward slope of the transport path,
The moving body will be horizontal or forward along the rail,
Package support for the moving body by the second attitude control means.
The rotation of the holding member is restricted, and the package support member is

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIGS. 1 to 3 show a ceiling conveying apparatus 1 according to an embodiment of the present invention. In the figure, an overhead conveying device 1 is pulled to the roller chain 2 along a rail 3 having an endless roller chain 2 inserted therein and having a cylindrical cross section and an inner bottom surface for roller guide on both sides of a lower opening portion. It is mainly composed of a carrier 4 that is moved. Carrier 4
Is hung on the rail 3 and is appropriately
A moving body 4a fixed at a distance , a package supporting member 4b for suspending and supporting the package P, and first posture control means (16, 1) for controlling the posture of the package supporting member 4b.
8) and a second attitude control means (17) .

The moving body 4 a supports a pair of rollers 6, 6 at both ends of a pin 7 at the top of a link 5 provided at each end of the swinging board 8, and the pair of rollers 6, 6 Place so that it rolls on the bottom. A package supporting member 4b is swingably supported at the center of the swinging board 8 by a shaft 10 in a virtual vertical plane parallel to the transport direction.

The package supporting member 4b is integrally formed by providing a plate-like base 13 below two plate members 11 and 12 arranged in parallel on both sides of the oscillating base 8, and forming an L-shaped base below the base 13. Is hung down from the bar. The tip of the support portion of the hanger 14 is provided substantially horizontally without being bent upward in consideration of workability when inserting and removing the package P. And, the top Symbol plate 11
Is extended above the shaft 10 to form a lever 15,
A guide roller 16 (first attitude control) is provided on the upper end of the lever 15.
It is provided with a control means) to freely rotate. 17 is the plate 1
1 and the plate 12, and the package support member 4
1b (a second pin) for restricting the rotation of counterclockwise in FIG.
Attitude control means) .

As shown in FIG. 1, a guide rail 18 (first posture control means) for controlling the posture is provided on the rail 3 on the downhill portion D of the conveying path, which is in contact with the guide roller 16. The guide rail 18 is provided along the trajectory of the guide roller 16 when the moving body 4a is moved along the downhill portion D of the rail 3 while keeping the attitude of the package support member 4b horizontal. The rail 3 is clamped and fixed to the rail 3 by a fastening bolt 21.

Next, the operation will be described based on an embodiment.

When the rail 3 is in a horizontal state, the front and rear rollers 6, 6 of the carrier 4 of the ceiling conveying device 1 are almost horizontal.
The moving body 4a (oscillating substrate 8) also has the same height in the front-rear direction and maintains a horizontal state. However, when the carrier 4 reaches the downhill portion D, the moving body 4a moves forward and downward along the inclination of the rail 3. Become . However, the package support member 4b is moth Idorora 16 is guided by the guide rail 18 holds the horizontal position by the swinging in FIG 1 in the counterclockwise direction is restricted, the package P that is supported on the hanger 14 By its own weight
As a result, unnecessary swing is prevented and a stable supporting state is ensured.

Further, when the carrier 4 reaches uphill portion of the rail 3 (not shown), the pin 17 is the moving body 4
a to restrict the rotation of the package support member 4b with respect to
The position of the package support member 4b is held upward in parallel with the moving body 4a to prevent the package P from falling off, and to reduce the weight of the package P by its own weight.
4b is fixed in that position, preventing unnecessary rocking.

The pin 17 (second attitude control means)
Moves forward and swings with the movement of the rail 3
It also has a function to prevent it. Further, in the downhill portion D, the rail 18 is protruded further below the illustrated example,
The position of the package supporting member 4b may be set slightly upward to more positively prevent the package P from falling off.

[0016]

As described above, the ceiling transport device of the present invention has a structure as described above.
As a result , the package is held in a predetermined posture over the entire area of the conveyance path including the downwardly inclined part of the conveyance path, the supporting state is stable, the package is prevented from falling off, and the Can be transported. Ma
Also, attitude control in consideration of the characteristics of the package as a transported object
Means in front of the package at the downward slope of the transport path
First attitude control means for preventing tilting,
Horizontal or reverse forward tilt of the package at the upward slope
That the second posture control means that holds the posture
Therefore, the guide rail of the first attitude control means is located below the conveyance path.
Only need to be provided on the inclined part, which simplifies the configuration of the device.
And reduce running resistance, noise and vibration.
There are advantages too.
