Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to flexible elongate storage devices, such as cables for supplying electrical power or transmitting electrical signals, and hoses for transporting fluids.

BACKGROUND ART The technique of stacking such flexible elongated bodies in a figure-eight shape in a horizontal plane has been known for a long time, and this allows the elongated bodies to be smoothly stored and supplied. The excellent advantage is that there is no need for a combination of a slip ring and a brush, or for a rotary pipe joint, which are necessary when winding onto a reel.

Problems to be Solved by the Invention In the prior art in which such elongated bodies are stacked in a figure 8 shape in a horizontal plane, there is no means for guiding the elongated bodies over the entire range in which the longitudinal bodies are stacked in a figure 8 shape. , configured to move. Therefore, the means for guiding the elongated body must be moved over a wide range, resulting in a problem of increased size.

SUMMARY OF THE INVENTION An object of the present invention is to provide a storage device for flexible elongated bodies that is compact in construction and that allows elongated bodies to be stacked in a figure-eight shape over a relatively wide area.

Means for Solving the Problems The present invention comprises: a base disposed above a storage location for a flexible longitudinal body and movable in a predetermined first direction within a horizontal plane; a truck that moves in a second direction intersecting the first direction; an arm provided on the truck and capable of angular displacement about the vertical axis; and an arm provided at a position offset from the vertical axis of the arm to guide the elongated body. and means for driving the base and the trolley to travel and driving the arm to angularly displace the longitudinal body in a horizontal plane at the storage location over a range larger than the movement range of the base and the trolley. This storage device is made up of flexible longitudinal bodies that can be stacked in a figure-eight shape.

Effect According to the invention, the means for guiding the elongate body is provided at a position offset from the vertical axis of the arm, and this arm is provided on the truck so as to be angularly displaceable about the vertical axis. The base is movable in a first direction within a horizontal plane, and a cart is provided on the base so as to be movable in a second direction. Therefore, by moving the base and the truck so that the longitudinal body forms a figure 8 shape in the horizontal plane while angularly displacing the arm, the range of movement between the base and the truck can be reduced. Moreover, it becomes possible to stack the elongated bodies in a figure 8 shape over a large area. In this way, a flexible elongated storage device that is small and lightweight is realized.

Embodiment FIG. 1 is a longitudinal sectional view of an embodiment of the present invention.
FIG. 2 is a plan view of the embodiment. Storage location 1
In this case, the flexible elongated bodies 2 are stacked and stored in a figure-eight shape in a horizontal plane, as indicated by reference numeral 3 in FIG. Above the storage place 1, there are rails 4 extending in a predetermined first direction (perpendicular to the plane of the paper in FIG. 1, vertical direction in FIG. 2) within a horizontal plane.
5 are provided, and the rails 4, 5 are provided with wheels 6,
A frame-shaped base 8 having a shape of 7 is movable.
The base 8 has rails 9 and 10 extending in a second direction perpendicular to the first direction (left-right direction in FIGS. 1 and 2).
is installed. A truck 13 having wheels 11 and 12 is provided on the rails 9 and 10 so as to be movable along the second direction. A motor 14 for driving the wheels 6 and 7 is provided to allow the base 8 to self-propel in the first direction. Further, the truck 13 is equipped with a motor 15 that drives the wheels 1 and 12 so that the truck 13 can self-propel in the second direction.
An arm 17 that can be angularly displaced around a vertical axis 16 is provided at the bottom of the truck 13 . This arm 1
7 is rotatable about its axis 16 by a motor 19 via a gear train 18 and can be angularly displaced. A means 20 for guiding the elongated body 2 in the vertical and longitudinal directions is provided at the distal end of the arm 1 at a position offset from the axis 16. The guide means 20 has a horizontal axis and includes a plurality of rollers 22 that support the elongate body 2 by sandwiching its outer periphery therebetween. The longitudinal body 2 passing through the guide means 20 is moved by a roller 2 provided near the axis 16.
3, the longitudinal body 2 is guided by the drive means 24 in the vertical direction in FIG. The driving means 24 includes a pair of rollers 25 and 26 having horizontal axes, and a pair of endless belts 27 and 28 endlessly wound between these rollers 25 and 26.
26 by the motor 29, the belts 27, 28 are driven to run in the same direction on the longitudinal body 2 side, and thus the belts 27, 2
The longitudinal body 2, which is compressed by the rollers 8, is displaced and driven in its length direction.

FIG. 3 is a block diagram showing the electrical configuration of the embodiment shown in FIGS. 1 and 2. FIG. The processing circuit 30 drives and controls the motors 14, 15, 19, and 29. When the elongated bodies 2 are stacked in a figure 8 shape in the storage location 1 by the drive of the motors 14, 15, the vertical axis 16 of the arm 17 follows a trajectory indicated by reference numeral 32 in FIG. The power of the motor 19 causes an angular displacement of the arm 17, so that the guide means 20 traces a trajectory indicated by reference numeral 33 in FIG. In this way, even if the movement range of the base 8 and the trolley 13 is relatively small, the elongated bodies 2 can be stacked in a figure-eight shape in the horizontal plane over a larger range. It is. Long body 2
When piling up the motor 29, the guide means 20
A slight tensile force is applied to the part of the elongate body 2 hanging down from the base, and the part is lowered downward. As a result, the longitudinal body 2 can be stably stacked in a figure-eight shape.

FIG. 4 is a plan view of the elongated bodies 2 stacked in a figure 8 shape. The figure 8-shaped parts l1 to l4 are stacked with their intersecting positions P1 to P4 shifted in the direction of the arrow 32. Thereafter, as shown in the figure 8 portions l5 to l8, their intersecting positions P5 to P8 are shifted in the direction of the arrow 33 and stacked. Such an operation is repeated, so that at the intersection positions P1 to P8, the elongated bodies 2 can be stacked with substantially uniform heights without being piled up and overlapping.
Therefore, the stacked figure-eight longitudinal bodies 2 are
Maintains a stable posture. The intersecting positions P1 to P8 may be stacked in another manner, for example, in a circular manner.

Effects As described above, according to the present invention, it is possible to stack the flexible longitudinal bodies in a figure-eight shape in a horizontal plane over a range larger than the movement range of the base and the trolley. be. Therefore, the configuration of the storage device of the present invention can be made smaller and the weight can be reduced.
