Abstract

PURPOSE:To enable shifting in all directions in a plane by coupling shift operating devices with the device body, wherein each shift operating device is capable of revolving round a longitudinal axis. CONSTITUTION:A plurality of traveling devices for shifting 6 are installed at a certain spacing in the transport direction of the device body concerned 1, wherein each traveling device shall be capable of revolving by a revolving rail 11. Here, traveling crawlers 7a, 7b of each traveling device for shifting 6 are set in the width direction of the device body 1, and travel shifting in the width direction is accomplished by driving these crawlers 7a, 7b. A revolutional setting of crawlers 7a, 7b so as to become parallel with the rails 10a, 10b of the body 1 will provide shifting into the transport direction. Thus shift in all directions in a plane can be obtained by revolving each traveling device 6 appropriately.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a belt conveyor device having a self-propelled function.

(Prior Art) Conventionally, as shown in Japanese Unexamined Patent Publication No. 59-43714,
There was a belt conveyor device that had a self-propelling function, in which each skid of a group of conveyor skids that was integrated by a traveling rail such as a trippa stacker, etc., and that was in contact with the ground was equipped with a shifting traveling device that moved forward and backward in the width direction of the conveyor. .

(Problems to be Solved by the Invention) However, in the above device, although it is possible to shift in the conveyor width direction, it is not possible to shift in the conveyor transport direction or in a diagonal direction with respect to the conveyor width direction. was causing a decline in

Therefore, in view of the above problems, the present invention provides a belt conveyor device that can run and shift not only in the width direction of the conveyor but also in the conveying direction of the conveyor and in diagonal directions with respect to the width direction of the conveyor, that is, in all directions in a plane. With the goal.

(Means for Solving the Problem) The technical means is that a belt conveyor 3 that can freely circulate is mounted, and a shift traveling device 6 is mounted on the conveyor 3 at a distance from each other in the conveying direction below the device main body 2. In a belt conveyor device 1 having a self-propelling function, in which a plurality of shift traveling devices 6 are provided, each of the shift traveling devices 6 is connected to the device main body 2 so as to be freely rotatable around a vertical axis.

(Function) According to the present invention, the belt conveyor 3 is operated by rotating each shift traveling device 6 in a predetermined direction with respect to the conveyance direction of the conveyor 3 and simultaneously driving each traveling device 6. It is possible to move in a predetermined direction while maintaining a straight line in a plane. At this time, since each of the shift traveling devices 6 is connected to the device main body 2 so as to be able to rotate freely, each traveling device 6 can be rotated with respect to the device main body 2 as appropriate, so that any shift can be achieved on a plane. You can shift the vehicle in any direction.

(Embodiment) Hereinafter, a first embodiment of the present invention will be described based on the drawings. In FIGS. 1 to 5, 1 is a belt conveyor device, and a belt conveyor 3 is mounted on the upper part of the device main body 2, and carrier rollers 4 A plurality of shift traveling devices 6 are installed at a lower part of the conveyor 3 at predetermined intervals in the transport direction of the conveyor 3.
is provided. Each of the traveling devices 6 is provided with a pair of rollers 7a and 7b that can freely rotate and rotate in both directions. a and 7b are arranged parallel to each other. Support frames 8a and Bb for rollers 7a and 7b that run both ways
A so-called cross-shaped swing support bar 9 is installed between them. On the other hand, the device main body 2 mainly consists of a pair of running rails 10a and 10b arranged parallel to each other,
An annular swing rail 11 is connected and supported between the lower surfaces of both rails 10a, 10b at a predetermined interval in the longitudinal direction of both rails 10a, 10b. In addition, the turning rail 11
The center post support bar 1 is installed in a radial direction and in a cross shape.
At the center of the swing rail 11, a vertical center post 1 provided on the swing support bar 9 is provided.
3 is pivotally connected to the center post support bar 12 so as to be relatively rotatable. Further, a pair of movable turning rollers 14a, 14b are provided on the upper surface side of each support frame 8a, 8b along the lower surface of the turning rail 11, respectively.

And the turning rail 11 of each turning roller 14a, 14b
Each traveling device 6 is freely pivotable around the vertical axis of the center post 13 via the lower surface rotation.

Reference numeral 15 denotes a stringer frame for a conveyor, which is erected on the turning rail 11, as shown in FIG. In addition, in Fig. 2, 16 is a tripper stacker, and each rail 1
0a and 10b can be freely operated.

In order to drive the rollers 7a and 7b of each running device 6, a drive mechanism such as a motor or a chain is provided as appropriate.

And a pair of running rollers of each running device 6? a+7b
When the wheels travel in opposite directions, the travel device 6 is rotated around the center post 13 in a so-called spin turn.

Therefore, each traveling device 6 can be freely rotated in any direction about the center post 13.

The first embodiment of the present invention is constructed as described above, and each traveling device 6 is connected to a belt conveyor 3 as shown in FIG.
The roller that runs each time after being set in the width direction? a, 7
If both wheels b are simultaneously driven in the same direction, the conveyor 3 can be shifted in the width direction. Further, as shown in FIG. 6, after each traveling device 6 is rotated and set in the conveying direction of the belt conveyor 3, the rollers for each traveling are set. If a and 7b are simultaneously driven in the same direction, the conveyor 3 can be shifted in the transport direction.

Further, as shown in FIG. 7, after each traveling device 6 is rotated and set diagonally with respect to the width direction of the belt conveyor 3, the rollers 7a are moved each time.

7b in the same direction at the same time, the conveyor 3 can be shifted in a diagonal direction with respect to the width direction of the conveyor 3. As described above, the belt conveyor device 1 can be shifted in any direction in a plane while maintaining its linear state, and has excellent maneuverability. Furthermore, deviations in the conveyance direction of the belt conveyor 3 can be easily corrected. Furthermore, since it can run diagonally, the growth height can be adjusted freely without changing the length of the belt conveyor device 1, and since it can run in the conveying direction of the conveyor 3, it can penetrate even narrow cultivated areas.

8 to 13 show a second embodiment, in which the rollers 7a on which each traveling device 6 runs are of a single construction.

Then, as shown in FIGS. 8, 12, and 13, by turning each traveling device 6 to a predetermined position, the vehicle can be shifted in any direction as described above.

FIG. 14 and FIG. 15 show a third embodiment, and by running the running roller 7a, a pair of turning rollers 14 are moved on the lower surface of the turning rail 11, and the turning rail 1
It is said that it can be rotated freely at the center opening of 1.

(Effects of the Invention) According to the present invention, in a belt conveyor device having a self-propelled function, each shift traveling device is connected to the device main body so as to be able to rotate freely around the vertical axis. The device can be moved horizontally in any direction, providing excellent maneuverability. In addition, it is possible to easily correct deviations in the conveyance direction of the belt conveyor, and it also has the advantage of being able to penetrate even narrow cultivated areas.
