It relates to a method of coupling the rails.

In general, various unmanned conveyance trucks are used for conveying materials, semi-finished products or parts in industrial sites such as production lines or assembly lines.

The unmanned conveyance trolley is a device that moves materials or products in a factory automated production line and carries materials or products, and operates according to a command received from a host computer using power of a bus bar for rails as a power source. The conveying trolleys include AGVs that move while reading induction devices arranged on the floor, and rail guided vehicles (RGVs) moving along a certain track depending on the size, precision, or difficulty of the product applied to the system.

In the assembly between the rails of the RGV is a connection structure consisting of a simple assembly using a plate made of a precision degradation due to the step between the two rails generated at this time, the shaking and separation of the product driven on the rail was formed.

That is, by forming a fixed block of the rail to be fixed to the upper portion and at the same time to be configured for the fixing block in the lower portion is to be precisely configured to transfer the trolley to be transferred on the rail.

In the rail to be transported, the two rail connections are fixedly mounted so that the movement of the trolley moves with high precision and high speed. Therefore, there is a problem in that it is difficult to precisely control the trolley, that is, stop at the correct position.

As described above, the roller rotated by the motor rotates at a high speed on the rail by the high rotational power of the motor. At this time, a high speed rotation of the roller by the motor causes a sliding phenomenon and a shaking phenomenon between the roller and the rail. Malfunctions may occur

A conventional method for joining a rail for a transfer truck is "LONGITUDINAL TRANSFER SYSTEM" of US005617796.

The above system is provided with a groove portion having a shape of "상부" at the top of the rail, and the groove portion is formed in a rectangular shape with a ball insertion groove for inserting a circular ball at a predetermined interval along the longitudinal direction. The connecting member is vertically formed, and a connecting member is formed in which a cutting groove having a narrower width is formed from the bottom of the ball insertion groove to the bottom surface.

When joining the upper part of the rail and the adjacent rail, the connection member is seated so as to span all the recesses of each rail, and the head is tightened by inserting a flat head bolt while the ball is inserted into the ball insertion groove. By moving toward the bottom side by opening the incision groove outwards both outer peripheral surfaces of the connecting member is in close contact with the inner wall of the groove portion to secure the two rails.

However, in the above method, since the ball insertion groove and the cutting groove must be formed separately in the connection member, the formation of the connection member is complicated, and the coupling method is complicated because the bolt is inserted in the state where the ball is inserted. There was a problem.

The present invention has been invented to solve the above problems, and an object of the present invention is to precisely connect the rails and adjacent rails so that the conveyance of the truck is smoothly configured.

In order to solve the above problems, the present invention extends to the neck and the upper portion of the neck portion, the groove portion is formed in a "┗┛" shape along the longitudinal direction at the center of the upper side and downward on both sides of the groove portion. It is formed in a diagonal direction and extends from the lower part of the head and the neck comprising an inclined surface for guiding the movement of the bogie while supporting the rail of the bogie, and is formed at predetermined intervals up and down along the longitudinal direction on both outer peripheral surfaces thereof. Balanced conveyance consisting of a trunk portion including a pair of busbar insertion grooves formed with a locking jaw to prevent separation of the busbar at the inlet side and a cutout groove formed in the inner direction at the lower portion of the busbar insertion groove In the method of coupling the trolley transfer rail for coupling the rail with the adjacent transfer rail, the width of the narrower than the groove portion A bottom surface is formed, and a body having a 45 ° inclined surface is formed on one side, and is formed along a longitudinal direction at the center of the body, and is spaced apart by a predetermined distance to one side from the center of the body, so that a plurality of fastening holes vertically. A first connection member having a predetermined length; It is formed in a shorter length than the first connecting member, the bottom surface is formed in a narrower width than the groove portion, the body is provided with an inclined surface of 45 ° is formed on one side, is formed along the longitudinal direction in the center of the body And a pair of second connecting members spaced apart by a predetermined distance from the center of the body by a predetermined distance to form a plurality of fastening holes vertically, wherein the first connection is connected to a connection portion of the transport rail adjacent to the transport rail. Position the member, and seat the bottom surface of the first connecting member so as to be located on the recess of each transfer rail, and then the pair of second connecting members are seated on the upper portion of the first connecting member. Position the inclined surfaces to face each other and then close the fastening holes of the respective connecting members to correspond to each other, and insert and tighten the bolts to penetrate the fastening holes of the respective connecting members. As the second connecting member descends along the inclined surface of the first connecting member, the outer peripheral surfaces of the first connecting member and the second connecting member are respectively in close contact with both inner walls of the recess, and two adjacent conveying rails are coupled.

In addition, the lower end of the body portion is formed in the shape of an inverted trapezoidal shape and protruded in the longitudinal direction upwards in the center of the base, but in the horizontal direction a plurality of fastening holes formed at a predetermined interval integral or mutual coupling is possible The lower bracket is formed to be in close contact with each other, and the cutout groove of the body portion and the fitting groove corresponding to the corner of the base are formed to be coupled to the lower bracket and the body portion, and the position corresponding to the fastening hole of the close portion. Side brackets are formed in the fastening hole is in close contact with the left, right direction, by inserting a bolt to pass through the fastening hole of the side bracket to be fixed to the fastening hole of the close contact portion characterized in that the two adjacent conveying rail is coupled.

In addition, the busbar insert grooves are formed to have a predetermined length, and both sides of the busbar seating part may support the busbar seating part on which the busbar is seated and one end of the busbar seated on the busbar seating part. A first release preventing part bent vertically from an end but bent in an inward direction, and formed at an upper end of the busbar seating part so as to support the other end of the busbar; A booth formed on a bottom surface of the second departure preventing part and the busbar seating part formed in a shape corresponding to the first departure preventing part and supported by a locking jaw of the busbar insertion groove to prevent departure. A bar fixture is inserted to prevent direct contact between the busbar and the transfer rail, and the busbar is connected to the connection portion of the transfer rail and the transfer rail. Characterized in that the fixed static.
