ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a transporting apparatus for individual sheets, in particular banknotes, having a frame on which there are provided a first transporting path, a second transporting path, which is directed at an angle to said first transporting path, and, at the connecting location between the two transporting paths, a diverter arrangement with a first diverter surface which, together with a first frame-side directing surface, bounds a first connecting path, which leads from the first transporting path to the second transporting path, and with a second diverter surface which, together with a second frame-side directing surface, bounds a second connecting path, which leads from the second transporting path to the first transporting path, it being the case that the two diverter surfaces can be adjusted alternately such that, when the first connecting path is opened, the first transporting path is interrupted and the inlet opening from the second transporting path into the second connecting path is closed and, when the latter is opened, the inlet opening from the first transporting path into the first connecting path is closed and the first transporting path is released.
A transporting apparatus of the type mentioned above may be provided, for example, on a storage apparatus for storing banknotes, for example a winding store, it being the case that the first transporting path is guided past the outside of the store housing or frame, while the second transporting path is intended to guide into the store the banknotes which are to be stored or to guide out of the store banknotes which are to be discharged.
A transporting apparatus of the type mentioned above is known, for example, from EP 0290731 B1. In the case of the transporting apparatus described in this document, the diverter arrangement comprises a strip-like diverter body with an essentially triangular cross section. Two of the triangle sides form the first and the second diverter surfaces and are curved concavely in adaptation to the convexly curved frame-side directing surfaces. At its longitudinal ends, the diverter body is fitted on two levers, with the result that it can be pivoted about an axis parallel to its longitudinal direction. The two levers can be adjusted linearly in their longitudinal direction via a drive, with the result that the diverter body can be adjusted between a first position, in which the first diverter surface butts against the first directing surface, and a second position, in which the second diverter surface butts against a second directing surface. If the diverter body, in the first position, is pressed against the first directing surface by way of its first diverter surface, then it assumes a pivot position in which the third, straight triangle side is aligned with the frame-side surface bounding the first transporting path. The other surface of the first transporting path is formed by a fixed plate. In the second position, in which the second diverter surface is pressed onto the second directing surface, the diverter body tilts such that the first diverter surface projects into the first transporting path by way of its edge which is adjacent to the third, straight triangle side of the diverter body, with the result that the individual sheets arriving via the first transporting path are directed into the first connecting path. As a result of the combined lifting and pivoting movement, a relatively large amount of space is required for the diverter body. It is not possible for the gap to be set individually for the two connecting paths.
SUMMARY OF THE INVENTION
The object of the invention is to design a transporting apparatus of the type mentioned in the introduction such that the diverter arrangement requires only a small amount of space, allows individual setting of the width of the connecting paths and can nevertheless be produced inexpensively and straightforwardly.
This object is achieved according to the invention in that the first diverter surface and a third diverter surface, which forms an acute angle with the first diverter surface and bounds part of the transporting path, are formed on a first strip-like diverter body, which extends over the width of the transporting paths and can be adjusted in a translatory manner between a first position, in which the third diverter surface is located in a surface which bounds the first transporting path and the first connecting path is closed, and a second position, in which the third diverter surface has been lifted out of the surface which bounds the first transporting path and the first connecting path is open, in that the second diverter surface is formed on a second strip-like diverter body, which is parallel to the first diverter body and is mounted such that it can be pivoted about a pivot spindle parallel to the respective transporting plane of the transporting paths, and in that the two diverter bodies are coupled to a drive arrangement for the synchronous adjustment of the diverter bodies.
In the case of the solution according to the invention, it is possible for the two diverter bodies to be adjusted synchronously but with different adjustment paths, with the result that the connecting paths may be configured differently and may be made to have different widths. Nevertheless, the two diverter bodies can be accommodated in an extremely small amount of space. It is also possible for the diverter arrangement according to the invention to be arranged in a convexly curved surface which bounds the first transporting path on the frame side and may be combined with a transporting belt for transporting the individual sheets.
If the first and the second connecting paths, as in the case of the known solution described above, converge toward a gap between two transporting rollers of the second transporting path, it is advantageous if, between the location at which the two connecting paths converge and the roller gap, a blocking strip, which is parallel to the diverter bodies, is arranged in an adjustable manner such that, in the first position of the first diverter body, it screens those edges of the diverter bodies which are directed toward the roller gap and blocks the first connecting path and, in the second position of the first diverter body, it releases the first connecting path. This prevents the situation where sheets running to the diverter arrangement on the second transporting path strike against the first and/or second diverter body. The blocking strip reliably ensures that, in this case, the individual sheets are directed into the open, second connecting path.
Synchronous adjustment of the two diverter bodies, despite the different adjustment movements of the latter, can be easily realized inexpensively in that the first diverter body is connected to at least one rack, which is guided in an at least more or less linearly displaceable manner on the frame, in that the second diverter body is connected to at least one toothed segment, which is curved coaxially with the pivot spindle of said second diverter body, and in that the rack and the toothed segment engage with a gear-wheel arrangement, which is seated on a pivot shaft which is parallel to the pivot spindle of the second diverter body and is connected to a pivot drive. Thus, despite the different adjustment movements of the two diverter bodies, one pivot drive is sufficient for adjusting the two diverter bodies. It is also possible for the adjustment path of the two diverter bodies to be set individually in that the gear-wheel arrangement comprises a first gear wheel, which engages with the rack, and a second gear wheel, which is coaxial with the first gear wheel and engages with the toothed segment. This makes it possible to select individually the transmission ratio for the adjustment of the two diverter bodies.
The blocking strip may easily be adjusted in that it is connected to at least one toothed segment, which is mounted such that it can be pivoted about a spindle parallel to the pivot shaft of the gear-wheel arrangement and which enga
