Abstract
Description
[Technical field]
[0001] This relates to transport device technology. [Background technology]
[0002] Conventional technologies related to transportation methods can be roughly categorized into two types. One is a method in which the object to be transported is placed on a cart and the wheels of the cart are driven. The other is a method in which a fixed power source drives a belt or wire, and the object is transported by the belt or wire.
[0003] Against this background, for example, Patent Document 1 proposes a conveying device that can improve the stopping position accuracy of a driven object in a conveying method in which multiple conveying units having pinion gears driven by a drive motor are installed on a plane.
[0004] Patent document 2 proposes a conveying device that simplifies the overall configuration by not using planar gears on the running plate that forms the traveling path, and that can prevent running problems such as gears riding up or becoming jammed and stuck when the running body moves. Moreover, Patent Document 3 proposes making it possible to reliably use a conveying device having a plurality of pallets. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] JP 2020-169081 A [Patent Document 2] JP 2019-089618 A [Patent Document 3] Japanese Patent Application Publication No. 07-242307 Summary of the Invention [Problem to be solved by the invention]
[0006] However, the above-mentioned conventional technology has a problem in that the structure of the conveying device is complicated.
[0007] In view of the above problems, an object of the present invention is to provide a conveying system capable of conveying an object in multiple directions using a simple mechanism that uses a fixed power source. [Means for solving the problem]
[0008] One form of the conveying system disclosed is a conveying system comprising a pallet of plate-shaped bodies and a roller device for moving the pallet, wherein the roller device comprises a cylindrical rotating body that rotates freely in both forward and reverse directions around an axis connecting the centers of both bottom surfaces of the cylinder, and roller protrusions that are protrusions arranged at predetermined intervals on a side surface of the cylinder from one bottom surface to the other bottom surface, and the pallet comprises pallet protrusions that are protrusions arranged on the underside of the plate-shaped body, and the pallet protrusions rotate freely in both forward and reverse directions in the planar direction of the plate-shaped body. Effect of the Invention
[0009] The conveying system disclosed herein is capable of conveying an object in multiple directions using a simple mechanism that uses a fixed power source. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a cross-sectional view of a pallet and a roller device according to the present embodiment. [Diagram 3] 11A and 11B are diagrams illustrating an example of an arrangement of pallet protrusions according to the present embodiment. [Figure 4] 5A and 5B are diagrams illustrating an example of an arrangement of roller devices according to the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the drawings, an embodiment of the present invention will be described. (Structure of the transport system according to this embodiment)
[0012] The structure of a conveying system 1 according to the present embodiment will be described with reference to Figures 1 to 4. Figure 1 is a perspective view showing an overview of the conveying system 1, Figure 2 is a view showing a cross-sectional structure of the conveying system 1, Figure 3 is a view showing an example of the arrangement of a pallet protrusion portion 6, and Figure 4 is a view showing an example of the arrangement of a roller device 8.
[0013] 1 and 2, the conveying system 1 includes a pallet 2 and a roller device 8. The pallet 2 forms a plate-like body 4 and has a pallet protrusion 6 which is a protruding portion disposed on the lower surface of the plate-like body 4. Since an object to be conveyed is placed on the upper surface of the plate-like body 2, it is preferable that the shape of the plate-like body 4 is, for example, a square or a rectangle.
[0014] 2, the pallet protrusions 6 rotate freely in both forward and reverse directions in the plane direction of the plate-like body 4. The pallet protrusions 6 have a function of reducing friction with the roller protrusions 16 described below.
[0015] 1 and 2, a plurality of pallet protrusions 6 are arranged on the underside of the plate-like body 4, and the arrangement rules (arrangement, spacing, etc.) can be in various patterns. As shown in Fig. 3, the pallet protrusions 6 are arranged, for example, on the diagonals of the square plate-like body 4, and it is preferable that they are also arranged regularly in positions other than the diagonals.
[0016] The roller device 8 has a rotating body 10 and roller protrusions 16. As shown in Figures 1 and 2, the rotating body 10 is cylindrical and can rotate in both forward and reverse directions around an axis 14 connecting the centers of both bottom surfaces 12 of the cylinder.
[0017] As shown in Figures 1 and 2, the roller protrusions 16 are protrusions arranged on the side surface of the rotating body 10 (cylindrical) from one bottom surface portion 12 to the other bottom surface portion 12, and are arranged at predetermined intervals. The roller protrusions 16 are cylindrical and rotate freely in the same direction as the rotating body 10, forward and backward. The roller protrusions 16 have the function of reducing friction with the pallet protrusions 6. As shown in FIG. 4, the roller devices 8 are preferably arranged regularly. The height of the roller protrusions 16 and the height of the pallet protrusions 6 can take various patterns, so they are not specifically or limited. (Method of using the transport system according to this embodiment)
[0018] The following describes how to use the conveyor system 1. The roller device 8 is rotated with the roller protrusions 16 and the pallet protrusions 6 in contact with each other. Then, the pallet 2 moves in the rotation direction of the roller device 8 (rotating body 10) with the pallet protrusions 6 being pushed by the roller protrusions 16.
[0019] Therefore, when a first guide 18 is installed to restrict horizontal movement with respect to the traveling direction of the pallet 2 (the rotation direction of the roller device 8 (rotating body 10)), the pallet 2 moves vertically along the first guide 18. On the other hand, when a second guide 20 is installed to restrict vertical movement with respect to the traveling direction of the pallet 2, the pallet 2 moves horizontally along the second guide 20.
[0020] As shown in Figure 4, assume that the roller devices 8 are regularly arranged, with a first guide 18 and a second guide 20 installed around them (on the outer edge). In this case, for example, when the roller device 8 at position (2,C) is rotated to the upper left, the pallet 2 at position (2,C) moves toward position (1,C). Also, for example, when the roller device 8 at position (3,C) is rotated to the lower right, the pallet 2 at position (3,C) moves toward position (3,B). Furthermore, for example, when the roller device 8 at the (1,A) position is rotated upward and to the left, the pallet 2 placed at the (1,A) position moves toward the (1,B) position.
[0021] 4, it is also possible to arrange the roller devices 8 in a regular pattern and use the pallets 2 arranged on the roller devices 8 as the first guide 18 and the second guide 20. For example, if the pallets 2 are arranged at positions (2,B), (3,B), and (2,C), and the roller device 8 at position (2,C) is rotated downward and to the right, the pallet 2 arranged at position (2,C) will move toward position (3,C). In this manner, the conveying system 1 is capable of conveying the object 2 to be conveyed in multiple directions with a simple mechanism that uses a fixed power source 8.
[0022] On the other hand, a method for moving the transport object in the height (high-low) direction will be described. First, two roller devices 8 are arranged so that their respective rotation axes 14 are perpendicular to each other and face each other. Next, one pallet 2 is placed on each roller device 8 so that the roller protrusions 16 and the pallet protrusions 6 abut against each other and the upper surfaces (the sides on which the transport object is placed) of the plate-like bodies 4 of the pallets 2 face each other. Then, the transport object is sandwiched between the upper surfaces of the plate-like bodies 4 of the two pallets 2.
[0023] As described above, when the two roller devices 8 are rotated in the same direction, in opposite directions, or only one of them is rotated, the transport object (pallet 2) can be moved up, down, left, right, or diagonally depending on the combination. In this manner, the conveying system 1 is capable of conveying the object 2 to be conveyed in multiple directions with a simple mechanism that uses a fixed power source 8.
[0024] Although the embodiment of the present invention has been described in detail above, the present invention is not limited to such specific embodiment, and various modifications and variations are possible within the scope of the gist of the present invention described in the claims.
