Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a circular object gripping device according to a first example of the present invention. FIG. 2 is a side view of FIG. 1.
FIG. 3 is an explanatory diagram showing a case where circular objects placed horizontally apart from each other are joined and placed vertically. FIG. 4 is an explanatory diagram showing a case where a circular object that is joined and placed horizontally is separated.

[0007] The circular object gripping device 1 comprises a base 2, a rotating body 3,
The main part of the rotating mechanism 4, the gripping mechanism 5, and the moving mechanism 6 is configured, and is applied to a cargo handling vehicle such as a forklift.

The base 2 forms a basic part of the circular object gripping device 1. In this example, the base 2 is a lifting body (lift bracket) that can move up and down a forklift, and rolls along a mast (not shown). A moving end roller 7 and a chain anchor 8 to which one end of a lift chain (not shown) is locked.
And

The rotating body 3 is provided so as to be rotatable around an axis in the front-rear direction (left-right direction in FIG. 2) with respect to the base body 2.
In this example, it is located on the front side of the base 2 and has a rectangular plate shape.

The rotating mechanism 4 rotates the rotating body 3 with respect to the base 2. In this example, the rotating mechanism 4 is interposed between the base 2 and the rotating body 3, and a motor ( A hydraulic motor) 9, a small gear 10 wedge-mounted on a rotating shaft thereof,
A large gear 11 meshed with the gear and fixed to the rotating body 3 is provided.

The gripping mechanism 5 is arranged side by side with the rotating body 3 in a lateral direction (a direction perpendicular to the longitudinal axis, that is, a direction perpendicular to the longitudinal axis, the horizontal direction in FIG. 1), and grips a circular object (roll paper) A. In this example, two frames are provided side by side on the left and right. In each of the frames, a frame 12, a long arm 13 provided on the upper part of the frame 12 so as to be swingable about a horizontal axis, and a frame 12 are provided. Arm 14, a clamp cylinder (hydraulic cylinder) 15 provided on the frame 12 for swinging the long arm 13, and swinging around the horizontal axis at each end of the long arm 13 and the short arm 14. It comprises a pad 16 movably provided, and a stopper 17 provided on each of the arms 13 and 14 to limit the swing of each pad 16.

The moving mechanism 6 moves at least one gripping mechanism 5 in the lateral direction with respect to the rotating body 3. In this example, only one (left) gripping mechanism 5 is moved relative to the rotating body 3. The upper and lower guide shafts 18 provided on the left front half of the rotating body 3 and the frame 1 of the left gripping mechanism 5 which are slidably inserted into these.
2 and a shift cylinder 20 provided on the rotating body 3 to move the frame 12 of the left gripping mechanism 5 in the horizontal direction. The frame 12 of the other (right) gripping mechanism 5 is fixed to the right front half of the rotating body 3.

Next, the operation will be described based on such a configuration. When the clamp cylinder 15 of each gripping mechanism 5 is operated, the long arm 13 swings with respect to the frame 12 and the pad 16 swings. When the long arm 13 and the pad 16 are swung, each arm 13,
The circular object A can be gripped between the fourteen pads 16.
When the motor 9 of the rotation mechanism 4 is operated, the rotation is reduced by the small gear 10 and the large gear 11, and the rotating body 3 and each of the gripping mechanisms 5 are rotated with respect to the base 2, and are gripped by the respective gripping mechanisms 5. The rotated circular object A can be rotated. Therefore, a plurality of horizontally arranged circular objects A can be vertically arranged, and conversely, a plurality of vertically arranged circular objects A can be horizontally arranged. When the shift cylinder 20 of the moving mechanism 6 is operated, the left gripping mechanism 5 is moved laterally with respect to the rotating body 3 by the guide shaft 18 and the guide pipe 19. Therefore, the circular objects A gripped by the gripping mechanisms 5 can be joined or separated from each other.

FIG. 3 shows a state in which two circular objects A placed sideways apart are gripped by each gripping mechanism 5 and lifted by a mast device (not shown) of a forklift.
The one circular object A is rotated by 90 degrees by the rotation mechanism 4 to make one of the circular objects A ground, and the other (upper) circular object A is moved by the moving mechanism 6 to be superimposed on the one (lower) circular object A. It shows the case where it is placed.

FIG. 4 shows a state in which two circular objects A which are joined and placed side by side are gripped by each gripping mechanism 5 and lifted by a mast device (not shown) of a forklift.
A case where one circular object A is moved by the moving mechanism 6 to separate the two circular objects A from each other is shown. Therefore, the operation of attaching a label or the like to the end face of the circular object A can be easily performed.

Next, a second embodiment of the present invention will be described with reference to FIGS. The second example differs from the first example in that the moving mechanism 6 moves the two gripping mechanisms 5 in the lateral direction. That is, the moving mechanism 6 is provided on the left and right in response to the left and right gripping mechanisms 5, and is provided with the guide shaft 18.
, A guide pipe 19 and a shift cylinder 20. In such a device, since both gripping mechanisms 5 are moved in the lateral direction, not only can both gripping mechanisms 5 be moved in different directions, but also in the same direction, so-called side shift. Can do things.

The base 2 is an elevating body in the above example. However, the invention is not limited to this. For example, a so-called hook type (hook-on type) removably attached to the elevating body may be used. In the above example, the rotating mechanism 4 uses the small gear 10 and the large gear 11, but the present invention is not limited to this. For example, a worm and a worm wheel may be used. Although the number of the gripping mechanisms 5 is two in the above example, the number of gripping mechanisms is not limited to two, and may be three or more. In the gripping mechanism 5, the short arm 14 is a fixed type in the above example, but is not limited to this, and may be, for example, a movable type. In the above example, the moving mechanism 6 has two gripping mechanisms 5, so that one of them is fixed and the other is moved, or both are moved. For example, when there are three or more gripping mechanisms 5, one of them is fixed and the rest is moved,
It may move everything. The moving mechanism 6
In the above example, the guide is performed using the guide shaft 18 and the guide pipe 19; however, the present invention is not limited thereto, and the guide may be performed using, for example, a rail and a roller. The moving mechanism 6 is driven using the shift cylinder 20 in the above example, but is not limited to this, and may be driven using, for example, a motor and a chain.
