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

In such a ceiling transfer device, an L-shaped hanger whose end portion is bent in the direction of travel is provided on a carrier that is pulled and moved by an endless chain along a rail so as to have the L-shape. The bent hanger tip is inserted into the bobbin of the package and the package is hung and transported, but the package support part of the hanger is almost horizontal in consideration of workability when inserting and removing the package. Since it is provided and supports the package in a forward direction, if there is a downhill part in the transport path, the supporting part may be lowered frontward 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 ceiling conveying apparatus, can prevent the conveyed articles from falling off at the downhill portion of the conveying path, and stabilizes the supporting state. It is an object of the present invention to provide a ceiling transfer device having such a structure.

[0005]

A carrier supporting member is rotatably provided on a swinging substrate of a carrier which is hung down on a rail and moves in a vertical plane including a moving locus of the carrier. A guide member provided to be displaced from the axis of rotation and a guide rail for guiding the guide member are provided.

[0006]

In the downhill portion of the transport path, the carrier is lowered frontward along the rail, but the support member is rotated relative to the carrier by the posture maintaining means so that the transport posture is horizontal or predetermined. In this state, the unsteady swinging is prevented, so that the supported state of the conveyed product is stable, and the conveyed product does not fall out.

In the figure, a ceiling conveying device 1 is pulled to the roller chain 2 along a rail 3 having an endless roller chain 2 inserted therein and having an inner bottom surface for roller guide on both sides of a lower opening portion having a tubular cross section. The carrier 4 is mainly configured to move by being moved. Carrier 4
Comprises a carrier suspension member 4a, a package support member 4b for supporting the package P, and a carrier attitude control member 4c integral with the package support member 4b. The carrier 4
Are hung on the rail 3 and fixed to the roller chain 2 at appropriate intervals.

The carrier suspension member 4a supports a pair of rolls 6 and 6 on both ends of a pin 7 on the top of a link 5 provided on both ends of the rocking substrate 8, respectively.
It is placed so as to roll on the inner bottom surface of the rail 3. A package support member 5 is swingably supported by a shaft 10 in the center of the swing substrate 8 in a virtual vertical plane parallel to the transport direction.

The package supporting member 4b is provided by integrating a flat plate-shaped base 13 under the two plate members 11 and 12 arranged in parallel on both sides of the oscillating substrate 8 and forming an L-shape under the base 13. The hanger 14 composed of a bar is hung. The tip of the supporting portion of the hanger 14 is provided substantially horizontally without bending upward in consideration of workability when inserting and removing the package P. Then, the carrier attitude control member 4c integrated with the package support member 4b is
The plate member 11 is extended above the shaft 10 to extend the lever 15
To form a guide roller 16 on the upper end of the lever 15.
The (guide member) is rotatably provided.
In addition, 17 is a pin fixed between the plate material 11 and the plate material 12 to regulate the rotation of the package support member 4b in the counterclockwise direction in FIG.

Further, as shown in FIG. 1, a carrier attitude control guide rail 18 is provided on the rail 3 at the downward slope portion D of the conveying path so as to come into contact with the guide roller 16.
The carrier attitude control guide rail 18 is provided along the locus of the guide roller 16 when the carrier 4 is moved along the downhill portion D of the rail 3 while horizontally maintaining the attitude of the package support member 4b. , 19 clamp the rail 3 and are fixed to the rail 3 by tightening bolts 21.

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

In the carrier 4 of the ceiling transfer apparatus 1, when the rail 3 is in a horizontal state, the front and rear rolls 6 and 6 are substantially horizontal, and the swinging substrate 8 has the same front and rear height and is also in a horizontal state. When the carrier 4 reaches the downhill portion D, the swing substrate 8
The package support member 4b is the weight of the package P supported by the hanger 14 of the package support member 4b and the carrier attitude control member integrated with the package support member 4b. 4c
