The present invention relates to a columnar conveying vehicle having a floating table for movably supporting a columnar object such as a roll of newspaper and a coil wound on a steel sheet.

Conventionally, the conveying vehicle which loads and conveys a columnar object can carry the columnar object to a columnar object receiving apparatus.

As an example of this conveyance vehicle, there is a traverser (not shown) which can be moved next to a three-prong reel (circular-shaped object receiving device) which supplies a roll to a rotary press, and guides the roll to a three-prong reel.

This traverser enters a pit formed at the bottom in the air, and when a truck loaded with a replacement scroll arrives from the paper warehouse, it is loaded under the three-prong reel 20 (see Fig. 8) installed next to the rotary press. It moves so that the trolley 22 may be raised as it is, and the roll W is hold | maintained by each arm 21 of the three reel 20.

The trolley | bogie is equipped with the function which loads the roll W on the table 25 of cross-sectional V shape, and runs.

The scroll conveyed by the traverser is held on each arm 21 of the three-pronged reel 20 shown in FIG. 8, held on one arm 21 of them, and one of the arms ( The paper of the scroll W1 held in 21 is drawn into the web printing machine (not shown).

The tip of the arm 21 is composed of the fixed arm 24 and the movable arm 23, as shown in FIG. The thread C is pressed by the fitting support 27 on the fixed arm 24 to support the scroll W. As shown in FIG.

When the traverser stops under the three reel 20, if the position of the scroll W is shifted with respect to the three reel 20, the scroll W is supported between the pair of fitting cones 26 and 27. There is a fear of not.

For this reason, the traverser can move freely with the trolley | bogie 22 when it stops under the three reel 20. As shown in FIG.

That is, the position of the roll W with respect to the three-prong reel is shifted in the X-axis direction (the direction connecting the pair of fitting cones 26 and 27), or the X-axis direction and the Y-axis direction (the X-axis in the horizontal plane). In the case of shifting in both directions with the direction orthogonal to the direction), the cart W can move as the roll W is picked up by the pair of raising cones 26 and 27.

Here, the stop accuracy of the traverser in the X-axis direction and the Y-axis direction is about ± 10 mm, respectively.

Moreover, the positional error of the roll W in the Z-axis direction (direction perpendicular to the X-axis and Y-axis) is about ± 3 mm.

In addition, as the scroll W is pressed by one of the fitting cones 26 to move in the Y-axis direction and pressed by the other of the fitting cones 27, the traverser is Y-axis together with the scroll W. Can move in the direction.

Here, the moving distance of the movable arm 23 is about 50 mm.

By the way, such a traverser has the following problem.

(1) You must form pit on the floor.

(2) Without a cart, a scroll cannot be carried on a three-prong reel.

(3) The height of the V-shaped surface of the bogie becomes the height that added the height of the traverser and the bogie's bogie, and the three reels cannot be lowered.

An object of the present invention for solving the above problems is that the overall height can be lower than the height overlapping the conventional trolley and the traserver, the conventional traverser is unnecessary, it is necessary to form a traverser pit on the floor The movable plate provides a columnar conveying vehicle having a floating table that allows the movable plate to be moved individually on a slope so that the loaded cylindrical form can be loaded in a stable state.

The above object includes a floating table for supporting a cylindrical shape and a lifting device for elevating the floating table, the floating table comprising: a movable frame in which a groove having a V-shaped cross section is formed and movable in a direction parallel to the groove; And a movable plate provided on the slope so as to move up and down along the groove, and an elastic body for applying a force in a downward direction to the movable plate provided between the movable plate and the slope, the movable plate of the movable frame It can be achieved by a transport vehicle that is arranged in a plurality of arrangement in the moving direction.

The conveying vehicle loads columnar objects on a floating table and runs to the side of the columnar object receiving device.

Thereafter, the transport vehicle raises the floating table while operating the lifting device.

The columnar object is supported by the movable plate of the floating table, approaches the columnar object receiving device, and is held in the columnar object receiving device.

When the columnar object is at a predetermined position with respect to the columnar object receiving device, the columnar object receiving device smoothly holds the columnar shape object.

For example, when the columnar object is shifted from the predetermined position, the columnar object receiving device holds the columnar object while correcting the position.

Correction of the position of the columnar product in the radial direction is permitted by the movement of the movable plate.
