[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In FIG. 1, the main body of a conveyed object 1 is supported by a plurality of conveyors 2 and conveyed thereon.

As shown in FIG. 2, distance adjustment devices are attached to both sides of the main body of the transported object 1. As shown in FIG. This consists of a pin 3 fixed to the main body of the conveyed object 1, a roller 6 rotatably attached to the pin 3, supports 4 and 5 rotatably suspended from the pin 3, and the supports 4 and 5. pin 7
It consists of rollers 8, 8 which are rotatably attached via the rollers 8, 8.

As shown in FIG. 1, the rollers 6, 8, and 8 can come into contact with guides 9 and 10 supported by a separately provided frame 27. Further, in FIG. 1, if the left end side is the upstream side in the conveying direction of the conveyor 2 and the right side is the downstream side, the roller 8 installed on the support 5 on the downstream side of the main body of the conveyed object 1 is the downstream side of the conveyed object. It is in contact with the roller 8 of the support 4 installed on the conveyed object. Due to the contact between the rollers 6 and the guide 9, the contact between the rollers 8 and 8 and the guide 10, and the contact between the rollers 8 and 8, the height and lateral positions of the device are restricted, and the position of the transported object 1 is restricted. is decided.

The overall configuration of this embodiment will be explained with reference to FIGS. 3 and 4. Supports 12a-1 erected from foundation 11
2h becomes shorter toward the downstream side in the conveyance direction. The conveyor 2, on which it rests via the plate 13, is tilted. Note that a stopper 1 is provided on the downstream side in the conveying direction via a bracket 14.
5 is installed. Now, when the conveyed object 1 is placed on the conveyor 2, it slides in the conveying direction due to its inclination, and the main body of the conveyed object 1 hits the stopper 15 and is held. When the objects to be conveyed are placed one after another, the distance between them is determined by the distance adjusting device and the guides 9 and 10, and the objects are placed over the entire length of the conveyor 2.

As shown in FIG. 5, the upper guide 9 that contacts the rollers 6 is installed parallel to the conveyor 2.
On the other hand, the lower guide 10 that contacts the rollers 8 is installed so that the distance from the guide 9 becomes smaller as it goes downstream.

Further, as shown in FIGS. 1 and 3, at the upstream end in the conveyance direction, the lower guide 10 projects further upstream than the upstream end of the upper guide 9. On the other hand, at the downstream end, the lower guide 10 projects further downstream than the downstream end of the upper guide 10.

Next, adjusting the distance between the objects 1 to be transported will be explained with reference to FIG. 5.As shown in FIG. The intervals become wider as a, b, and c.

In FIGS. 3 and 4, when the conveyed object 1n is removed from the conveyor 2 at the downstream end of the conveyor 2, the other conveyed objects 1 are successively conveyed one by one. By repeating this operation, the object 1 to be transported is transported.

In this case, the lower guide 10 is the upper guide 9
It protrudes further downstream. Further, the downstream end of the conveyor 2 also projects further downstream than the upper guide 9. Therefore, the conveyed object 1 is transferred to the conveyor 2.
It rests on the stopper 15 and stops. A guide 9 is provided above the main body of the transported object 1.
There is no. In this state, by lifting the most downstream object 1 upward, the object 1 (including the interval adjustment device) can be carried out.

Furthermore, since the upstream ends of the conveyor 2 and the lower guide 10 protrude further upstream than the upper guide 9, when the conveyed object 1 is placed on the conveyor 2, the distance adjusting device is adjusted between the guide 9 and the guide 10. It can be easily inserted between the two.

According to this configuration, since the conveyor 2 is installed at an angle, the conveyed object 1 is moved simply by being placed on the conveyor 2, so no special driving means is required, and the overall structure of the device can be simplified. It's easy to do. In addition, the guides 9 and 10 and the supports 4 and 5
Since they are arranged vertically, the installation space is small and the entire device can be made compact. Further, the distance between the objects 1 to be transported during transport is automatically adjusted by changing the shapes of the guides 9 and 10, and the distance can be adjusted as desired without requiring any input.

Furthermore, the upstream ends of the conveyor 2 and the guide 10 protrude above the guide 9, the downstream ends of the conveyor 2 protrude below the downstream end of the guide 9, and the presence of the stopper 15. , the object 1 to be transported can be easily loaded and removed.

〔Effect of the invention〕

As explained above, according to the present invention, the installation space is small and the configuration is simple, and the objects to be transported can be transported while gradually increasing the interval in the transport direction without using any special driving means. Further, it is possible to easily insert and remove objects to be transported.
