DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bogie conveyer in a bogie carrier used for carrying a car body on a bogie along a fixed route in an automobile factory, for example.

[0002]

2. Description of the Related Art A rail merging apparatus of this type has a rolling rail for connecting two bogie traveling upstream rails which are obliquely crossed to one bogie traveling downstream rail at an intersection. And the rail is 2
An upstream end located between the two upstream rails is horizontally swingably supported, and one of the two bogie traveling upstream rails and the downstream rail are connected to each other, and one of the upstream rails is When the point rail is retracted from the carriage conveyance path and the point rail is advanced into the conveyance path of the other upstream rail, the carriage traveling on the other upstream rail is the other. Collides with the point rail that has been entering the transport path of the upstream rail, pushes it, and is retreated from the transport path of the other upstream rail, and enters the transport path of one upstream rail. It is known that the other upstream rail is connected to the downstream rail instead of the one upstream rail.

[0003]

In the above-described apparatus, when the transport route of the bogie is switched, the bogie hits the rolling rail and pushes it, thereby swinging the rolling rail. Therefore, the impact when the bogie collides with the rolling rail generates a large sound. Furthermore, since the bogie moves while pushing the pivot rail, the bogie receives a large running resistance from the pivot rail.

[0004] Further, in this type of truck transport device,
A rubber feed roller is placed at a required point on the carriage transport path, and by pressing the feed roller against the carriage, the rotational force of the feed roller is transmitted to the carriage and the carriage is propelled, mounting while moving the carriage In order to work on the processed workpiece, from the viewpoint of workability and safety, the driving force of the feed roller is set to a degree that the cart can be stopped manually, so that when the cart is stopped, the feed roller idles. Has been made.

[0005] In the transfer device adopting such a system, the speed of the bogie is extremely reduced when the bogie passes over the turning rail, and in some cases, the bogie is stopped. Sometimes.

An object of the present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a bogie merging apparatus which can switch a point rail by a bogie quietly with a small force.

[0007]

SUMMARY OF THE INVENTION A bogie merging apparatus according to the present invention is a roller connecting two bogie traveling upstream rails which are obliquely crossed to one bogie traveling downstream rail at an intersection. The rail has a rail, and the rolling rail is supported so as to be horizontally swingable at an upstream end located between the two upstream rails, and a bogie transport of the two upstream rails at the downstream end. In a bogie merging device adapted to be alternately advanced and retracted in the path, an operation rod extending toward the upstream side is provided at an upstream end of the rolling rail, and a distal end of the operation rod is provided at the upstream end. The distal end of the operation arm extending toward the side is connected by a vertical pin, the base of the operation arm is fixed to one end of a vertical rotation shaft supported by a fixed support member, and to the other end of the rotation shaft, Horizontal platform Fulcrum engagement lever is fixed, both ends of the carriage engagement lever, and is characterized in that it is adapted to be moved back and forth alternately in the carriage conveying paths of the two upstream side rails.

In the bogie merging apparatus according to the present invention, an operating rod extending upstream is provided at the upstream end of the point rail, and an operating arm extending upstream is provided at the tip of the operating rod. The distal end is connected by a vertical pin, and the base of the operating arm is fixed to one end of a vertical rotation shaft supported by a fixed support member, and the other end of the rotation shaft has a fulcrum of a horizontal bogie engaging lever. Is fixed, and both ends of the trolley engaging lever can be moved back and forth on the same trolley transport path as the trolley transport path, so that one of the two trolley traveling upstream rails is connected to the downstream rail. When the rolling rail is retracted from the bogie transport path of one upstream rail, and the rolling rail enters the transport path of the other upstream rail, the other upstream rail is moved. Transport of side rail One end of a trolley engaging lever is advanced into the path, and when the trolley is engaged with the trolley, the trolley engaging lever is swung with the movement of the trolley. Is retreated from the transport path, the swing of the bogie engaging lever is transmitted to the pivot rail by the operation arm and the operating rod, and the pivot rail is also swung in the same direction as the bogie engaging lever. The point rail is moved away from the transport path of the other upstream rail. Therefore, when the bogie passes the point rail, since the point rail has been retreated from the transport path in advance, the bogie does not contact the point rail, and the bogie does not contact the point rail. However, since the vehicle can pass the place, the switching of the point rail by the bogie can be performed quietly with a small force.

Referring to FIGS. 11 and 12, a horizontal operating rod 91 is fixed to the mounting boss 82 of the point rail 62. The operation rod 91 protrudes upstream from between the top plate 71 and the bottom plate 72 of the support base 61. Operation rod
An elongated hole 92 extending in the width direction is formed at the protruding end portion 91. On the other hand, a vertical support cylinder 93 is fixed to the rear edge of the upper surface of the support base top plate 71 so as to be positioned above the operation rod 91. A vertical rotation shaft 94 is fitted into the support cylinder 93 so that both upper and lower ends thereof protrude from the support cylinder 93. The base of the operating arm 95 is fixed to the lower end of the rotating shaft 94. The operating arm 95 extends upstream from the operation rod 91 so as to overlap the operation rod 91 when viewed from above.

A roller 97 is fitted over the vertical pin 96, and the vertical pin 96 is fitted into the elongated hole 92 via the roller 97. On the other hand, an L-shaped engagement lever 98 is fixed to the upper end of the rotating shaft 94 at a bent portion thereof. A pair of left and right horizontal contact rollers 99 are attached to both ends of the engagement lever 98, respectively.

As shown by the solid lines in FIGS. 6 and 12, when the first upstream rail 51 and the downstream rail 53 are connected by the rolling rail 62, the right contact roller 99 is moved to the first upstream side. The left abutment roller 99 is retreated from the carriage moving path of the rail 51, and enters the carriage moving path of the second upstream roller 52. Further, the vertical pin 96 is located at the left end of the long hole 92. On the other hand, as shown by a chain line in both figures, in a state where the second upstream rail 52 and the downstream rail 53 are connected by the rolling rail 62, the right abutment roller 99 is connected to the first upstream rail 51. The left abutment roller 99 is made to enter the carriage movement path, and is withdrawn from the carriage movement path of the second upstream roller 52.

Referring to FIG. 10, the mounting height of the contact roller 99 is set so that the contact roller 99 is brought into contact with the trolley 31 at the middle of the height of the side plate 41 passing therethrough. Is set.

FIGS. 6 and 12 show the first upstream rail 51.
This shows a state in which the bogie 12 can pass from to the downstream rail 53. In this state, the bogie 12 moves on the second upstream rail 52, and the first trolley 31 is moved.
The first trolley that moves when it reaches the left contact roller 99
31 abuts against the left abutment roller 99 and pushes it toward the downstream side, and the engagement lever 98 is swung counterclockwise in both figures. Due to this swing, the left contact roller 99 is retreated from the carriage conveyance path of the second upstream rail 52, and the right contact roller 99 is advanced into the carriage conveyance path of the first upstream rail 51.

The swing of the engagement lever 98 is transmitted to the operation rod 91 by the operation arm 95 and the vertical pin 96, and pushes the operation rod 91 counterclockwise. Then, the operating rod 91 is swung in the counterclockwise direction together with the switching rail 62, whereby the switching rail 62 is moved to the second upstream rail.
Switching is performed so as to connect the downstream rail 53 to the downstream rail 52. When the pressing of the left abutment roller 99 by the first trolley 31 is completed and the swing of the pivot rail 62 is stopped, the entire pivot rail 62 is moved from the bogie transport path of the downstream rail 53. Without being completely retreated, a part of the right edge of the pivot rail 62 remains in the bogie transport path of the downstream rail 53. The first trolley 31 that has passed through the contact roller 99 abuts on this entry portion, and further swings the pivot rail 62 counterclockwise, so that the entire pivot rail 62 is located on the downstream side. The rail 53 is completely retreated from the carriage transport path, and the right and left stopper surfaces 86a and 88a of the turning rail 62 facing right.
Is brought into contact with the right rail member 21 of the downstream rail 53.
During this time, the vertical pin 96 is moved from the right end to the left end in the elongated hole 92. At the time of switching, the pivoting of the pivot rail 62 is performed separately in the first stage in which the trolley 31 pushes the contact roller 99 and in the second stage in which the pushing rail 62 is pushed. Accordingly, the impact when the rolling rail 62 comes into contact with the left rail member 21 of the downstream rail 53 is reduced.

After the above switching, the first upstream rail is again turned on.
In order to switch the connection between the first rail 51 and the downstream rail 53 by the rolling rail 62, the first trolley 31 traveling on the first upstream rail 51 comes into contact with the right contact roller 99, and the engagement lever 98 Is pivoted clockwise together with the pivot rail 62.

According to the present invention, the switching of the point rail by the bogie can be performed quietly with a small force.
