DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an outer cylindrical body (for example, a cylindrical can filled with a beverage or a cylindrical intermediate product used in producing the can) for the next step. The present invention relates to a transfer device (hereinafter simply referred to as a transfer device) for transferring an outer cylindrical body.

[0002]

2. Description of the Related Art FIG. 4 shows such a conventional transfer apparatus. That is, this is for transporting an intermediate product (hereinafter, referred to as a cup) C used for can production to a press device 1 for drawing the cup C, and is capable of dropping a plurality of cups C in a vertical direction. And a rod 4 provided below the shooter 2 and advanced and retracted by an actuator 3. The cup C located at the lowermost position of the shooter 2 is protruded from the rod 4 to the press device 1. I try to push it. At this time, another cup C located behind the cup C pushed by the rod 4 is freely dropped along the shooter 2 so as to prepare for the next pushing into the press device 1.

[0003]

However, in the conventional transfer device, the cup C to be pushed next into the press device 1 is allowed to freely fall, so that the cup C collides with another member at the time of free fall. In addition, there is a problem that noise is generated, and there is a problem that dents and scratches are generated in the cup C at the time of a collision, which may leave a defect in a can as a product.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables the outer cylindrical body to be smoothly transported without free falling, thereby suppressing the generation of noise to a very small extent. An object of the present invention is to provide a transport device that can prevent dents and scratches on the surface of a cylindrical body.

[0005]

According to the transfer apparatus of the present invention, a pair of feed guides for temporarily stopping the transfer of the outer cylindrical body to be transferred downward and then sending it downward are provided on both sides of the transfer path. The feed guides are arranged in a state of entering the road, and each of the feed guides is driven to rotate in the opposite direction to each other, has a substantially circular outer peripheral surface substantially centered on the rotation axis, and a part of the outer peripheral surface of the feed guide. A concave portion is formed to wrap around the outer cylindrical body from the left and right while being driven to rotate and is sent downward, and a convex portion for pressing the outer cylindrical body sent from inside the concave portion from above is formed continuously with the concave portion. On both sides of the transport path below the feed guide, a pair of rollers that support the outer cylindrical body wrapped in the concave portion and sent downward are pressed before being pressed by the convex portion. Vignetting, wherein the biasing mechanism is provided for urging the pair of rollers in the direction to protrude the conveying path.

[0006]

According to the transfer apparatus of the present invention, the outer cylindrical body comes into contact with the outer peripheral surface of the feed guide which has entered the transfer path, and the transfer is temporarily stopped. Here, when the feed guide is driven to rotate, the outer cylindrical body is sent downward while being wrapped from the left and right by a concave portion formed on a part of the outer peripheral surface of the feed guide. At this time, the outer cylindrical body sent downward is supported by the pair of rollers and prevented from falling. Further, when the feed guide is rotated, the outer cylindrical body supported by the roller is pressed from above by the convex portion formed on the outer peripheral surface of the feed guide. As a result, each of the rollers retracts from the transport path while opposing the urging force of the urging mechanism, and the outer cylindrical body is smoothly fed downward.
