1 to 5, the logistics system using a multi-sided rail according to an embodiment of the present invention may include a rail unit 100, a side moving cart unit 200 and an upper moving cart unit 300. have.

First, the rail unit 100 may be installed spaced to a certain height from the floor or wall or floor of the workshop. The rail unit 100 may be formed to extend in the form of a straight line, or may be formed to extend in a curved form as necessary. The rail unit 100 may serve to guide the mobile truck units 200 and 300, which will be described later.

In this embodiment, the rail unit 100 may be installed to be spaced to a predetermined height from the floor by a support (S) supported on the bottom surface.

Looking at the shape of the rail unit 100, the rail unit 100 may be formed with an upper movement slit 110, a lower movement slit 110 and a side movement slit 110 on the upper, lower, and side portions, respectively. In other words, the rail unit 100 may be formed of four surfaces, and the width for each surface may be formed identically. However, the width of the rail unit 100 is not limited to the same.

For reference, hereinafter, the upper moving slits 110, the lower moving slits 110 and the side moving slits 110 are all of the same shape, and the upper side and the lower side can be changed according to the arrangement direction of the rail unit 100.

Both inner walls of the side movement slits 110 may have a shape protruding in a curved shape inward. The wheel member W1 of the side moving cart unit 200, which will be described later, may be seated on the side moving slits 110 and moved.

A fixed slit 120 may be formed inside the side movement slit 110. The fixed slits 120 may be formed in a groove shape from the side movable slits 110 toward the center of the rail unit 100. In addition, the fixed slit 120 may have a line width smaller than the line width of the side movement slit 110. Both inner walls of the fixed slits 120 may be formed in a straight line shape. The fixed slit 120 may be used as a space for a specific object to be fixedly coupled, such as a support S for supporting the rail unit 100.

The upper movable slit 110 and the lateral movable slit 110 and the lower movable slit 110 of the logistics system using the multi-faced rail according to the embodiment of the present invention may be formed in the same form. That is, the upper movement slit 110 and the side movement slit 110 and the lower movement slit 110 may be determined based on the direction in which the rail unit 100 is disposed according to the rotation.

For example, if the movable slit 110 and the fixed slit 120 are not separated from the rail unit 100 having multiple faces, the support S for supporting the rail unit 100 must be installed in the movable slit 11. At this time. During the installation of the support (S), the movable slit 110 may be bent or a hole may be formed by a screw. That is, later, when the moving cart units 200 and 300 are seated on the corresponding moving slits 110 of the rail unit 100, a play between the wheel member W1 and the rail unit 100 occurs, and noise and vibration may be generated. Can be.

However, each of the upper moving slit 110 and the side moving slit 110 and the lower moving slit 110 of the present invention is provided in the rail unit 100 because the moving slit 110 and the fixed slit 120 are separately provided. Even if the object for fixing is combined, there is no fear of damage to any one of the moving slits 110.

In this embodiment, a support (S) may be installed in the fixing slit 120 of the lower moving slit 110 positioned in the lower direction of the rail unit 100.

In this embodiment, the surface of the rail unit 100 may be formed of a polygonal surface, such as 3 or 5, rather than 4. For example, when the rail unit 100 is formed in three sides, the cross section of the rail unit 100 may be formed in a triangular shape.

An upper moving cart unit 300 and a side moving truck unit 200 may be seated and moved on the upper moving slits 110 and the side moving slits 110 formed on the rail unit 100, respectively.

A plurality of wheel coupling holes 221 may be formed in the side plate member 220. The wheel coupling hole 221 may be continuously formed in a direction parallel to the longitudinal direction of the rail unit 100. For reference, at least one of the plurality of wheel coupling holes 221 may be formed to be out of line with the other wheel coupling hole 221, which will be described again below.

Wheel members W1 may be installed in each of the wheel coupling holes 221 of the side plate member 220. The wheel member W1 may be formed in a shape corresponding to the inner wall of the side movement slit 110. For example, since the wheel member W1 and the side movement slit 110 are formed in a shape of a curve corresponding to each other, it is possible to prevent the wheel member W1 from being detached from the side movement slit 110.

In this embodiment, the number of wheel members W1 is shown, but the number of wheel members W1 is not limited to any one.

Side plate member 220 may be formed with a gap control piece 222 is formed by cutting a portion.

The clearance adjustment piece 222 formed as described above may have elasticity in a direction orthogonal to the longitudinal direction of the side movement slit 110. Here, the degree of elasticity of the clearance adjustment piece 222 may be equal to the incision width of the incision around the adjacent circumference of the wheel coupling hole 221.

In other words, since the clearance adjustment piece 222 is formed by cutting a part of the circumference of the specific wheel coupling hole 221, when an external force is applied, the incised part may be bent and restored again. .

And, as shown in Figure 3, at least one wheel engaging hole 221 formed in the clearance adjustment piece 222 is to be arranged to deviate a predetermined distance from the central axis connecting the center of the plurality of wheel engaging hole 221 Can be. That is, the wheel member W1 installed on the clearance adjusting piece 222 may be installed to deviate from the center line connecting the other wheel members W1. For reference, for convenience of description, the wheel member W1 installed in the clearance adjustment piece 222 will be described as a clearance adjustment wheel W2.

For example, the width of the side movement slits 110 may have a wider width than the width of the wheel member W1. At this time, when the side moving cart unit 200 moves, noise and vibration may occur due to the clearance between the side moving slits 110 and the wheel member W1. The clearance adjustment piece 222 has an advantage of minimizing noise and vibration by minimizing the clearance by adjusting the distance between the plurality of wheel members W1 and the side movement slits 110 through the clearance adjustment wheel W2.

A plurality of fastening holes 223 may be formed through the side plate member 220. Fastening means such as a bolt nut for fastening the basket to the upper plate member may be fitted into the fastening hole 223. The number or shape of the fastening holes 223 may be formed in various numbers and shapes. In this embodiment, the fastening hole 223 may be formed at a position adjacent to the circumference of the side plate member 220.

As mentioned above, the side moving cart unit 200 and the upper moving cart unit 300 may have the same configuration and be formed in the same form. However, the side moving cart unit 200 may be formed to have a height that does not exceed the uppermost end of the rail unit 100 when installed in the rail unit 100. This is to avoid interference with each other when the upper moving cart unit 300 and the side moving truck unit 200 are moved on the same rail unit 100.

On the other hand, the logistics system using a multi-faced rail according to an embodiment of the present invention may further include a mounting unit 400. The mounting unit 400 may be made of a wheel and a mounting plate 920.

The wheel of the mounting unit 400 may be formed in the same shape as the wheel member W1 of the mobile trucks described above and seated on the lower moving slit 110. In this embodiment, the wheel of the mounting unit 400 may be fixedly coupled to the fixing slit 120 formed in the lower portion of the rail unit 100. At this time, the shape of the wheel of the mounting unit 400 may be formed in a shape corresponding to the fixed slit 120.

A mounting plate 420 may be coupled to the wheel of the mounting unit 400. The mounting plate 420 may be formed in a plate shape so that one end is coupled to the wheel and the other end extends toward the outside of the rail unit 100. The mounting plate 920 may serve to mount a work tool or the like at the work site.

Looking at the operation of the logistics system using the multi-faced rail according to an embodiment of the present invention configured as described above, the rail unit 100 may be installed in a straight or curved form as a predetermined path to the work site. For reference, a support (S) for separating the rail unit 100 from the floor may be installed on the fixing slit 120 formed at the bottom of the rail unit 100.

In addition, the upper moving cart unit 300 and the side moving cart unit 200 may be moved along the upper moving slits 110 and the side moving slits 110 of the rail unit 100, respectively. For example, depending on the working environment, the upper movable cart unit 300 may move forward and the side movable cart unit 200 may move in the opposite direction to the upper movable cart unit 300.

At this time, since the side shifting bogie unit 200 moves along the side shifting slit 110 provided separately from the top shifting bogie unit 300, it moves in a desired direction regardless of the moving direction of the top shifting bogie unit 300. It may be possible.

In addition, the lower moving slit 110 of the rail unit 100 may be mounted or fixed to the mounting unit 400 for mounting a work tool or the like.

Therefore, the logistics system using the multi-faced rail according to an embodiment of the present invention increases the efficiency of work because it can utilize a plurality of mobile carts and mounting units 400 even when one rail unit 100 is installed. In order to move the mobile cart toward the rear, there is an advantage of minimizing the working time since unnecessary movement for removing the other mobile truck is not required.
