A configuration of the transport rail coupling bracket 10 according to the embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view illustrating a configuration of a transport rail coupling bracket 10 according to the present embodiment. FIG. 2 is a diagram illustrating a configuration of the transport rail coupling bracket 10 according to the present embodiment. 2A is a front view of the transport rail coupling bracket 10, FIG. 2B is a rear view of the transport rail coupling bracket 10, and FIG. 2C is a top view of the transport rail coupling bracket 10. FIG. ) Is a bottom view of the transport rail coupling bracket 10, (e) is a left side view of the transport rail coupling bracket 10, and (f) is a right side view of the transport rail coupling bracket 10.

  The transport rail connecting bracket 10 is a substantially rectangular long plate-shaped metal member, and is used to connect two transport rails. In the present embodiment, the metal member constituting the transport rail coupling bracket 10 is galvanized iron. In addition, as a metal member, aluminum or stainless steel can also be used.

  In the transport rail coupling bracket 10, the length in the short direction (hereinafter referred to as “height”) differs in the long direction, and the height gradually increases from both ends in the long direction toward the center. On the other hand, the thickness of the transport rail coupling fitting 10 is substantially uniform.

  In the transport rail coupling bracket 10, a short length is provided on both the upper surface 12 (one end surface in the short direction) and the lower surface 14 (the other end surface in the short direction) at the center in the long direction, specifically, in the center in the long direction. Protrusions 13 projecting outward in the direction are provided.

In the transport rail connecting bracket 10, a through-hole 11 is formed in the central portion in the longitudinal direction so as to penetrate in the thickness direction from the front surface to the back surface. The through-hole 11 has a substantially rectangular shape when viewed from the front and the back, and has substantially the same height in the longitudinal direction. In the present embodiment, the through-hole 11 is approximately half the width of the transport rail connecting bracket 10 with respect to the length in the longitudinal direction (hereinafter referred to as “width”). As described above, the transport rail connecting bracket 10 has a plate shape and the through hole 11 is formed in the center portion. The degree of elastic deformation can be adjusted by changing the size and position of the through-hole 11 and the thickness and material of the transport rail coupling bracket 10.
Next, the connection method of the 1st conveyance rail 20 and the 2nd conveyance rail 30 by the coupling bracket 10 for conveyance rails which has the said structure is demonstrated using FIGS.

  3, 4, and 5 are a perspective view, a plan view, and a plan view for explaining a method of connecting the first transport rail 20 and the second transport rail 30 using the transport rail coupling bracket 10 according to the present embodiment, respectively. It is a side view.

  In the method of connecting the first transport rail 20 and the second transport rail 30, first, as shown in FIG. 3A, FIG. 4A, and FIG. The first transport rail 20 and the second transport rail 30 are disposed so as to face each other. In this arrangement state, the lengthwise direction of the first transport rail 20 and the second transport rail 30 and the lengthwise direction of the two transport rail connecting brackets 10 coincide.

  Here, the first transport rail 20 includes a long U-shaped rail member 21 having a substantially U-shaped cross section, and a roller member 22 that is rotatably held by the rail member 21 and on which an object to be transported is placed. It is configured. The rail member 21 includes a substantially rectangular long plate-like bottom surface portion and two hollow rectangular column-shaped side surfaces formed so as to rise from both ends of the bottom surface in the short direction. This coincides with the conveyance direction of the object to be conveyed on one conveyance rail 20. The roller member 22 has a rotation shaft that is rotatably spanned between the two side surface portions of the rail member 21, and rotates around the rotation shaft. The two side surface portions of the rail member 21 have openings 23 into which the transport rail connecting bracket 10 can be inserted on the end surface of the first transport rail 20 in the longitudinal direction.

Similarly, the second transport rail 30 is composed of a long rail member 31 having a substantially U-shaped cross section, and a roller member 32 that is rotatably held by the rail member 31 and on which an object to be transported is placed. It is configured. The rail member 31 includes a substantially rectangular plate-like bottom surface portion and two hollow rectangular column-shaped side surface portions formed so as to rise from both ends in the short direction of the bottom surface portion. It corresponds with the conveyance direction of the to-be-conveyed object of the 2 conveyance rail 30. FIG. The roller member 32 has a rotation shaft that is rotatably spanned between the two side surface portions of the rail member 31, and rotates around the rotation shaft. The two side surface portions of the rail member 31 have openings 33 into which the transport rail connecting bracket 10 can be inserted on the end surface of the second transport rail 30 in the longitudinal direction.
In this embodiment, the rail members 21 and 31 are made of galvanized metal such as iron, and the roller members 22 and 32 are made of synthetic resin. At this time, aluminum or stainless steel can be used as the metal of the rail members 21 and 31.

  Next, as shown in FIGS. 3B, 4 </ b> B, and 5 </ b> B, two transport rails are formed in the two openings 33 on the transport rail coupling bracket 10 side of the second transport rail 30. One end of the connecting metal fitting 10 in the longitudinal direction is inserted.

  Next, as shown in FIGS. 3 (c), 4 (c), and 5 (c), the two transport rail connecting brackets 10 inserted into the two openings 33 of the second transport rail 30 are: The two metal fittings 10 for the transport rail are beaten in the longitudinal direction with a rubber hammer and pushed into the inside of the side surface of the second transport rail 30 in the longitudinal direction.

  At this time, the height at both ends in the longitudinal direction of the transport rail coupling fitting 10 is lower than the height of the opening 33 in the side surface portion of the rail member 31. And the height in the center part of the elongate direction of the coupling bracket 10 for conveyance rails is more than the height of the opening 33 of the side part of the rail member 31. As shown in FIG. Accordingly, when the conveyance rail coupling bracket 10 is pushed into the second conveyance rail 30, the upper surface 12 and the lower surface 14 of the conveyance rail coupling bracket 10 come into contact with the inner surface of the opening 33 in the vertical direction, so that the conveyance rail coupling is performed. The metal fitting 10 and the 2nd conveyance rail 30 fit.

  When the conveyance rail coupling bracket 10 is further pushed in even after the conveyance rail coupling bracket 10 and the second conveyance rail 30 are fitted, the central portion of the conveyance rail coupling bracket 10 is pressed so as to be sandwiched in the short direction. Thus, the height of the central portion of the transport rail coupling bracket 10 is lowered. However, since the convex part 13 which protrudes in a short direction is provided in the center of the elongate direction of the connection bracket 10 for conveyance rails, the insertion part pushes in the connection bracket 10 for conveyance rails, and the insertion part reaches to the center of the elongate direction. When reaching, the side surface of the convex portion 13 comes into contact with the opening end of the opening 33 in the vertical direction. As a result, the convex portion 13 is hooked on the opening end of the opening 33 in the vertical direction, and further insertion of the transport rail connecting bracket 10 is restricted. By such insertion using the convex portion 13 as a stopper, it becomes possible to reliably insert the right half of the longitudinal direction of the transport rail coupling bracket 10 into the second transport rail 30.

  Finally, in the same manner as the insertion into the second conveyance rail 30, as shown in FIGS. 3D, 4D, and 5D, the first conveyance rail 20 is connected to the conveyance rail. The other ends of the two transport rail connecting brackets 10 in the longitudinal direction are inserted into the two openings 23 on the bracket 10 side. After that, the two metal fittings 10 for the transport rail inserted into the two openings 23 of the first transport rail 20 are engaged with the opening 23, and then the projection 13 is caught until the vertical opening end of the opening 23 is caught. It is pushed toward the longitudinal direction further inside the side surface portion of one transport rail 20. By such insertion using the convex portion 13 as a stopper, it becomes possible to reliably insert the left half in the longitudinal direction of the transport rail connecting bracket 10 into the first transport rail 20.

  By the above connection method, it is possible to realize the connected transport rail 40 including the transport rail connecting bracket 10 and the two first transport rails 20 and the second transport rail 30 connected by the transport rail connecting bracket 10. Similar to the first transport rail 20 and the second transport rail 30, the connection transport rail 40 is arranged such that its longitudinal direction is inclined with respect to the ground, so that the rollers 22 and 32 can rotate the rollers. The objects to be conveyed placed on the members 22 and 32 can be conveyed in the longitudinal direction by the weight of the objects to be conveyed.

  As described above, the transport rail connecting bracket 10 according to the present embodiment is a connecting bracket that connects the two first transport rails 20 and the second transport rail 30 that transport the object to be transported, and the two first transport rails. It is a plate-like member that can be fitted simultaneously into the openings 23 and 33 formed on the end surfaces of the 20 and the second transport rail 30 in the transport direction.

  With such a configuration, the two first transport rails 20 and the second transport rail 30 can be connected by the transport rail connecting bracket 10 to form a long transport rail. Therefore, even when the transport distance is extended with respect to the previous distance, there is no need to prepare a new transport rail. For example, a long transport rail is configured by connecting short transport rails that have been scrapped. Can do. As a result, it is possible to realize the transport rail coupling bracket 10 that can easily cope with the extension of the transport distance of the object to be transported.

  Further, since the connection between the two first transport rails 20 and the second transport rail 30 can be realized by a lightweight member called a plate-like member, the two first transport rails 20 and the second transport rails 20 are suppressed while suppressing an increase in weight. The conveyance rail coupling bracket 10 capable of coupling the conveyance rail 30 can be realized.

In addition, the connection of the two first transport rails 20 and the second transport rails 30 can be realized by a simple method of fitting the plate-like members to the two first transport rails 20 and the second transport rails 30. It is possible to realize the transport rail coupling bracket 10 that can easily connect the two first transport rails 20 and the second transport rail 30.
Moreover, the through-hole 11 penetrating from the front surface toward the back surface is formed in the transport rail connecting bracket 10 of the present embodiment.

  With such a configuration, the transport rail connecting bracket 10 is easily elastically deformed by the force toward the through hole 11 received by the fitting between the two first transport rails 20 and the second transport rail 30, and the fitted state is increased. Can be strongly maintained. As a result, it is possible to realize the transport rail coupling bracket 10 capable of strengthening the connection between the two first transport rails 20 and the second transport rail 30.

  Further, the transport rail connecting bracket 10 of the present embodiment is in contact with the end surfaces of the first transport rail 20 and the second transport rail 30 in a state of being fitted with the two first transport rails 20 and the second transport rail 30. It has the convex part 13 which determines the fitting position of the two 1st conveyance rails 20 and the 2nd conveyance rail 30. FIG.

  With such a configuration, it is possible to prevent the fitting positions of the first transport rail 20 and the second transport rail 30 and the transport rail connecting bracket 10 from being varied in the plurality of connection transport rails 40. As a result, it is possible to realize the transport rail connecting bracket 10 capable of aligning the connection strengths of the first transport rail 20 and the second transport rail 30 with the plurality of connected transport rails 40.

As mentioned above, although the connection bracket for transport rails and the connection transport rail of the present invention have been described based on the embodiment, the present invention is not limited to this embodiment. The present invention includes various modifications made by those skilled in the art without departing from the scope of the present invention.
For example, in the above-described embodiment, the transport rail connecting bracket has a rectangular shape, but is not limited thereto as long as it can be fitted into the opening of the transport rail.

  Moreover, in the said embodiment, although the conveyance rail had the opening which the coupling bracket for conveyance rails fits in a side part, a bottom face part is a hollow prismatic shape and you may have an opening in the end surface of a bottom face part. . In this case, it is possible to connect the two transport rails by one transport rail connecting bracket.

  Moreover, in the said embodiment, the connection bracket for conveyance rails had a convex part in both the upper surface and the lower surface, and it was supposed that insertion to a conveyance rail was performed by using this convex part as a stopper. However, the convex portion of the transport rail connecting bracket may be provided only on either the upper surface or the lower surface, or provided on at least one of the front surface and the rear surface of the transport rail connecting bracket in the longitudinal direction. Also good. When a convex part is provided in the surface and back surface of the connection bracket for conveyance rails, the convex part protrudes outward in the thickness direction.

  Moreover, in the said embodiment, although the side part of the conveyance rail was hollow prismatic shape and the opening of the end surface of a side part was substantially rectangular shape seeing the conveyance rail from the elongate direction, it is not restricted to this. For example, the side surface portion of the transport rail may be a hollow prism having a groove running in the longitudinal direction, and the opening at the end surface of the side surface portion may be substantially C-shaped when the transport rail is viewed from the longitudinal direction.

  Further, in the above embodiment, the upper surface and the lower surface of the conveyance rail coupling bracket are brought into contact with the inner surface of the conveyance rail opening by insertion of the conveyance rail coupling bracket into the conveyance rail opening, so that the conveyance rail opening and the conveyance rail coupling are connected. Suppose that the metal fitting fits. However, the front and back surfaces of the transport rail connection bracket come into contact with the inner surface of the transport rail opening by inserting the transport rail connection bracket into the transport rail opening, and the transport rail opening and the transport rail connection bracket are fitted. May be. In such a configuration, for example, the thickness of the connecting bracket for the transport rail is set to be equal to or greater than the length in the left-right direction of the opening of the transport rail at the center in the longitudinal direction, and the left-right direction of the transport rail opening at both ends in the longitudinal direction. This can be realized by gradually reducing the thickness of the transport rail coupling metal fitting from both ends in the longitudinal direction toward the center. In this case, the height of the transport rail connecting bracket can be made constant below the height in the vertical direction of the opening of the transport rail.

Moreover, in the said embodiment, the connection bracket for conveyance rails was flat form, and it was supposed that two conveyance rails were connected so that a longitudinal direction might correspond, and a new linear conveyance rail was comprised. However, the transport rail connecting bracket may have a bent shape in which a flat plate is bent, and the two transport rails may be coupled so that the longitudinal direction intersects to form a new transport rail having a broken line shape.
Moreover, in the said embodiment, although the connection bracket for conveyance rails connected two conveyance rails, you may connect three or more conveyance rails.

  Further, in the above embodiment, the through-hole that facilitates elastic deformation of the transport rail connecting bracket is formed in the transport rail connecting bracket, but the thickness, material, etc. of the transport rail connecting bracket 10 are changed. When a desired elastic deformation is obtained by setting, the through hole may not be formed.

  Moreover, in the said embodiment, although the convex part was provided in the connection bracket for conveyance rails as a stopper in insertion to a conveyance rail, it is necessary to adjust the fitting position of a conveyance rail and the connection bracket for conveyance rails. When there is not, the convex part does not need to be provided.

  INDUSTRIAL APPLICABILITY The present invention can be widely used in connection fittings that connect conveyance rails that convey an object to be conveyed, and connection conveyance rails that are connected thereby.
