[0002]

2. Description of the Related Art Generally, in order to smoothly transfer packages between a stationary conveyer fixedly installed on the ground and a moving conveyer mounted on a trolley, it is required that the conveying surfaces of both conveyers are aligned flush with each other. To be done.

When a stationary conveyor and a moving conveyor are newly installed, a shim is inserted between the stationary conveyor and the ground,
The shim adjustment for adjusting the height of the shim aligns the carrying surface of the stationary conveyor with the carrying surface of the moving conveyor.

[0004]

However, if, for example, the ground is unequally settled after installation, a height difference occurs between the transfer surface of the moving conveyor and the transfer surface of the stationary conveyor, or the transfer surface of the moving conveyor is There is a problem that the transfer surface of the stationary conveyor is inclined around an axis parallel to the transfer direction, and the consistency of the transfer surfaces of both the movable and stationary conveyors is impaired.

DISCLOSURE OF THE INVENTION The present invention is directed to a baggage loading and positioning apparatus for a mobile conveyor, which aligns the transport surface of a mobile conveyor mounted on a carriage with the transport surface of a stationary conveyor installed on the ground. In order to achieve, the following technical measures are adopted.

That is, the load assembling and positioning apparatus for a mobile conveyor according to the present invention comprises a lift means for moving the mobile conveyor up and down, and at least one shift supported by the mobile conveyor so as to be able to move forward and backward toward the stationary conveyor. A rail and a pedestal supported by the stationary conveyor are provided, and the raised moving conveyor is lowered in a state where the shift rail is advanced, so that the shifting rail is received by the pedestal to move and stationary. It is characterized in that the conveying surfaces of the conveyor are aligned.

According to this method, the lift means is operated in advance to position the moving conveyor higher than the stationary conveyor, and then the shift rail is moved toward the stationary conveyor in the state where the shift rail is advanced toward the stationary conveyor. When the conveyor is lowered and the shift rail is received by the pedestal, the heights of the transport surfaces of the moving and stationary conveyors can be matched.

According to the present invention, if only one set of the shift rail and the pedestal is provided, the heights of the transfer surfaces of both the moving and stationary conveyors can be made equal as described above. There remains the problem that the movement around the axis parallel to the direction and the inclination of the conveying surfaces of both stationary conveyors cannot be matched.

Therefore, in the present invention, a pair of shift rails are supported at both ends in the width direction of the moving conveyor so as to be capable of advancing and retracting toward the stationary conveyor, and one of the shift rails is a pedestal. After that, the operation of the lift means is continued to allow the other shift rail to be received by the pedestal so that the inclination about the axis parallel to the transport direction of the moving conveyor is aligned with that of the stationary conveyor. Is preferred.

According to this structure, by continuously lowering the moving conveyor by the lifting means until the pair of shift rails are received by the receiving table, the heights of the conveying surfaces of both the moving and stationary conveyors are parallel to the conveying direction. It is possible to match the inclinations around different axes.

However, for example, when the lift means is provided with a plurality of hydraulic cylinders distributed at a plurality of positions on the moving conveyor, the loads shared by the respective hydraulic cylinders are different, and the hydraulic oil to the respective hydraulic cylinders is different. If the conditions for supplying and discharging are different, the expansion and contraction of each hydraulic cylinder becomes uneven, and the transfer surface of the moving conveyor may be twisted.

Therefore, in the present invention constructed so that the height and the inclination of the transfer surface can be matched, in order to prevent the transfer surface of the transfer conveyor from being twisted for some reason, the transfer of the transfer conveyor is prevented. It is preferable to provide a synchronization means for mechanically synchronizing the inclination of the plane about the axis parallel to the conveying direction over both ends of the moving conveyor in the conveying direction.

According to this, since the conveying surface of the moving conveyor is uniformly inclined over both ends in the conveying direction around the axis parallel to the conveying direction, the conveying surface of the moving conveyor is not twisted, and the conveying surface of the moving conveyor is prevented. The transport surface has a predetermined surface shape,
For example, it is inclined around an axis parallel to the transport direction while keeping a flat surface.

The synchronizing means may be constructed so as to mechanically synchronize the inclination about the axis parallel to the carrying direction of the carrying surface of the moving conveyor over both ends in the carrying direction of the moving conveyor. A rotary shaft that is rotatably supported around an axis parallel to the transport direction at two points on the conveyor frame that are spaced appropriately in the transport direction. It is possible to adopt a configuration in which two gears that are fixed together and a pair of racks that are individually meshed with each gear and that are fixed to the carriage are provided.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a load combining and positioning device for a moving conveyor according to an embodiment of the present invention will be specifically described with reference to the drawings. In the drawings, FIG. 1 is a configuration diagram showing a basic configuration of a luggage combining and positioning device for a moving conveyor according to an embodiment of the present invention. As shown in FIG. The moving conveyor 2 is supported so as to be able to move up and down via a lifting means 3 composed of, for example, four hydraulic cylinders, and the width direction of the moving conveyor 2, that is,
Traveling direction of trolley 1 (direction perpendicular to the plane of FIG. 1)
A pair of shift rails 5 are provided at both ends of the movable conveyor 2 so as to be able to move forward and backward toward the stationary conveyor 4 at a height equal to or lower than the conveying surface of the movable conveyor 2.
The shift rail 5 is configured to be driven forward and backward by a shift cylinder 6 which is, for example, a hydraulic cylinder.

In the lift means 3, for example, the upper limit position where the shift rail 5 is located higher than the carrying surface of the stationary conveyor 4 and the carrying surface of the moving conveyor 2 are the stationary conveyor 4.
The moving conveyor 2 is moved up and down to the lower limit position which is located lower than that.

By the way, at the end surface of the stationary conveyor 4 facing the moving conveyor 2, the height of the conveying surface of the stationary conveyor 4 and the height of the moving surface of the movable conveyor 2 coincide with each other toward the stationary conveyor 4. The shift rail 5 that has advanced
The pedestal 7 that abuts on the lower side is fixed.

The carriage 1 is installed on the ground GL 1
It is configured to be guided and moved by the pair of rails 8.
Further, in FIG. 1, reference numeral 9 is a guide rail for guiding the shift rail 5 forward and backward.

FIG. 2 is a side view of this embodiment, FIG. 3 is a plan view of this embodiment, FIG. 4 is a sectional view taken along the line A--A of FIG. 3, and FIG. It is sectional drawing of a part. In these figures, the moving conveyor 2 and the stationary conveyor 4
The configurations are not specifically shown because they are not related to the essence of the present invention, and detailed description of these configurations is also omitted in the present specification.

Now, as shown in FIGS. 2 and 3,
An axis parallel to the carrying direction of the carrying surface of the moving conveyor 2 across the carriage 1 and the moving conveyor 2 at the center of the pair of shift rails 5 in the width direction of the moving conveyor 2, that is, the horizontal direction orthogonal to the carrying direction. A synchronizing means 10 is provided for mechanically synchronizing the inclination of the surroundings over both ends in the transport direction of the moving conveyor 2.

As shown in FIGS. 2 to 5, the synchronizing means 10 is parallel to the carrying direction via the bearings 12 at two positions on the frame 11 of the moving conveyor 2 at appropriate intervals in the carrying direction. A rotary shaft 13 rotatably supported around an axis, two gears 14 fixed to the rotary shaft 13 at appropriate intervals in the transport direction, and individual gears 14 meshed with each other. It is provided with a pair of racks 15 fixed to the carriage 1.

Each rack 15 is fixed to a frame 16 of the carriage 1 and fixed to a guide plate 18 having a U-shaped guide groove 17, and the rotary shaft 13 is moved up and down in the guide groove 17 via another bearing 19. Insert as much as possible.

In this embodiment thus constructed, as shown in FIG. 1, the moving conveyor 2 is moved up to the upper limit position by the lift means 4 and the shift rail 5 is advanced, and then the moving conveyor 2 is moved to the stationary conveyor 4. When the lift means 3 is reversely operated after being moved to a position corresponding to, the shift rail 5 is eventually received by the cradle 7, and the transfer surface of the moving conveyor 2 reaches the height of the transfer surface of the stationary conveyor 4. Positioned.

Here, one of the pair of shift rails 5 may be received by the receiving table 7 before the other. In this case, the shift rail 5 is moved at the end portion where the shift rail 5 is received by the cradle 7, and the heights of the conveying surfaces of the two stationary conveyors 2 and 4 are the same, but at the opposite end portion, the moving conveyor 2 is moved. Since the transport surface of (1) is located higher than the transport surface of the stationary conveyer 4, the lift hand stage 3 is continuously reversely operated.

As a result, the moving conveyor 2 is inclined around the axis parallel to the carrying direction, centering on the end on the side where the shift rail 5 is first received by the receiving table 7. When the shift rail 5 on the opposite side is received by the pedestal 7, the heights of the transfer surfaces of the moving and stationary conveyors 2 and 4 coincide with each other over the entire width direction. Stop reverse operation.

By the way, in this embodiment, since the above-mentioned synchronizing means 10 is provided, when the moving conveyor 2 is tilted about the axis parallel to the carrying direction with one end in the width direction as the center, it is supported by the frame 11. The rotating shaft 13 descends, and the rotating shaft 13 rotates due to the engagement between the rack 15 and the gear 14. Due to the rotation of the rotary shaft 13, both gears 14 rotate mechanically in synchronization regardless of the load shared by the hydraulic cylinders of the lift means 3, so that both ends of the rotary shaft 13 always have the same height. Thus, the frame 11 supporting the rotating shaft 13 moves up and down at the same height at two positions separated in the transport direction. As a result, since the inclination of the moving conveyor 2 is the same at both ends in the carrying direction, the carrying surface of the moving conveyor 2 is not twisted around the axis parallel to the carrying direction.

As described above, according to this embodiment, the conveying surfaces of the moving and stationary conveyors 2 and 4 can be aligned over their entire width without twisting the conveying surface of the moving conveyor 2. Rough installation accuracy of the stationary conveyor 2, the rail 8 that guides the carriage 1, etc.,
The flatness of the traveling road surface of the carriage 1 can be roughened. In addition, the shift rail 5,
The present invention can be implemented easily and inexpensively by a simple modification in which the shift cylinder 6 is added and the cradle 7 is added to the existing stationary conveyor 4.

[0029]

As described above, according to the present invention, lift means for moving the moving conveyor up and down, and at least one shift rail supported by the moving conveyor so as to be able to move forward and backward toward the stationary conveyor, It is equipped with a cradle supported by a stationary conveyor, and by moving the raised moving conveyor down while the shift rail is advancing, it is moved by receiving the shift rail on the cradle and conveyed by both stationary conveyors. The feature is that the surfaces are aligned.

According to this, after the lift means is actuated to position the moving conveyor higher than the stationary conveyor in advance, the shift rail is advanced toward the stationary conveyor and the lifting means is operated in reverse to move. When the conveyor is lowered and the shift rail is received by the pedestal, it is possible to obtain an effect that the height of the transfer surface of the moving conveyor can be positioned at the same height as that of the stationary conveyor.

By this action, the effect that the luggage can be smoothly transferred between the moving and stationary conveyors can be obtained, and the installation accuracy of the stationary conveyor at the time of new installation,
The effect of being able to reduce equipment costs by roughening the installation accuracy of the rails that guide the dolly, the finishing accuracy of the road surface on which the dolly travels, and absorbing changes in the installation conditions of the transfer conveyor and stationary conveyor that occurred after installation. As a result, it is possible to obtain the effect that the luggage can be smoothly transferred between the stationary conveyors for a long period of time.

In the present invention, a pair of shift rails are supported at an appropriate interval at both ends in the width direction of the moving conveyor so as to be capable of advancing and retreating toward the stationary conveyor, and one shift rail is received by a pedestal. After that, by adopting a structure in which the inclination of the axis around the axis parallel to the transport direction of the moving conveyor is aligned with that of the stationary conveyor by continuing the operation of the lifting means and receiving the other shift rail on the cradle. Therefore, it is possible to obtain an effect that the height of the transport surface of the moving conveyor can be aligned with that of the stationary conveyor over the entire width direction.

Further, in this structure, if a synchronizing means for mechanically synchronizing the inclination of the conveying surface of the moving conveyor about the axis parallel to the conveying direction over both ends in the conveying direction of the moving conveyor is provided. It is possible to obtain the effect that the moving conveyor is not likely to be twisted even when the load conditions become uneven.
