Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a rod-shaped article conversion and transfer device for changing the direction of rod-shaped articles such as cigarettes and filter plugs.

(Prior art and its problems) It is necessary to change the direction of stick-shaped objects such as cigarettes and filter plugs when communicating between conveying machines or between processing machines and conveying machines.

The basic structure of the conventional turning and transferring device for rod-shaped objects was
To explain with reference to FIG. 5, in this conventional example, the direction of a rod-shaped object is changed by 90 degrees.

In the figure, B is a rod-shaped object, and A' is a guide plate. Each guide plate A' is a board whose upper edge A ₁ ' and lower edge A ₂ ' are twisted at 90 degrees, and are arranged at equal intervals l ₁ in the horizontal direction. It is configured to be kept.

The interval l ₁ between the guide plates A' is the same as or slightly wider than the length of the rod-shaped object B, and each end of the rod-shaped object B carried in is guided downward by the upper edge A ₁ ' of the guide plate A'. The direction of the object is changed by gradually dropping the object.

When the conventional example is used for rod-shaped objects of different lengths, the interval _l1 between the guide plates A' must be adjusted according to the lengths.

For example, in order to change the direction of a rod-shaped object having a length _l2 , the interval _l1 between the guide plates A' must be set to _l2 . In Fig. 15, the distance l ₁ is changed to l ₃ at the upper edge A ₁ ' of the guide plate A'.
Even if it is narrowed to l ₂ , at the lower edge A ₂ ' of guide plate A', the _distance will be
l ₁ remains unchanged.

That is, the conventional apparatus cannot handle rod-like objects of different lengths, and many types of guide plates corresponding to rod-like objects of various lengths must be kept in stock, which is very uneconomical.

Each unit guide plate a has an upper edge a ₁ and a lower edge
A ₂ is twisted by 18 degrees to form a curved guide surface A ₃ , and a long hole A ₄ is formed on the back side of the guide surface A 3 so that the distance between the unit guide plates A and A can be adjusted. There is.

Each side guide plate 3 is formed by forming the side surface of a cylindrical plate into an inclined shape to form a guide edge 3a, and a long hole 3b is formed on the back side of the side guide plate 3. The distance from 3 can be adjusted.

The lower step portion a5 of the unit guide plate a provided on the movable plate ₅ comes into contact with the lower movable plate 5 to open the lower movable plate 5 when the units 2 are stacked.

Further, the fixed frame 4 of the unit 2 has a circumferential direction.
The mounting holes 4b are opened at appropriate intervals by 18 degrees.

As shown in FIGS. 1 to 3, each of the units 2 is stacked on a mounting base 10 with a twist of 18 degrees, and as shown in FIG. Configure A.

To explain the twisted state of each unit 2, Fig. 1 shows the unit 2 in the first stage, Figs. 4 to 7 show the units 2 in the second to fifth stages, and Fig. 8 shows the mounting base 10.
