DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to an apparatus for turning small goods, particularly packages, on a conveyor belt.
Turning devices are known in which the small goods are stood up by means of a sloped roller track or the goods are turned by tipping them over.
Such devices have the drawback that they do not permit the goods to be in a defined position on the conveyor belt.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an apparatus for turning small goods in which the goods are pivotal about at least 90.degree. into any desired position. Moreover, the apparatus is to be configured so that the goods are transported away flush with the preceding and the subsequent conveyor belt.
One embodiment of the invention will now be described with reference to the attached drawing.
FIG. 1 is a perspective view of an apparatus according to the invention for turning small goods;
FIG. 2, shows the configuration of a pivot drive provided with articulated rods for the apparatus according to the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The small goods, a package, is marked 1 and lies on a conveyor belt 2. Conveyor belt 2 transports the package in the direction of the arrow toward a turning device 3. After the package has been pivoted on turning device 3, it moves upright into conveyor path 4 and is transported away in the direction of the arrow.
The device for turning the small goods 1 is composed of a lateral guide member 5 and conveyor belts 6 extending in the direction of conveyor belt 2. As shown in FIG. 2, conveyor belts 6 may also be made of one piece. Likewise, the lateral guide member 5 may be configured as a driven conveyor belt (FIG. 2).
The above object generally is achieved according to a first embodiment of the present invention by an apparatus for turning small goods, particularly packages, on a conveyor, wherein the apparatus is composed of first and second conveyor belts having respective transporting surfaces that are perpendicular to one another and form an independent component of the conveyor, with the first and second conveyor belts being arranged on a frame which is pivotal about 90.degree. by a pivot drive so that the transporting surface of the one of the first and second conveyor belts that is flush in the direction of the conveyor on the other transporting surface, once pivoted about 90.degree., is flush with the conveyor surface, and the transporting surface that was flush in the direction of the conveyor and with the conveyor surface before the pivoting process is perpendicular to the conveyor surface.
The above object is achieved according to a second embodiment of the invention by an apparatus for turning small goods, particularly packages, on a conveyor, which apparatus comprises: a horizontal transporting surface flush with a surface of the conveyor and extending in the direction of the conveyor and a guide surface extending in the direction of the conveyor and perpendicular to the transporting surface, with the transporting surface and the guide surface forming an independent component of the conveyor, the transporting surface is subdivided into partial conveyor belts and has rectangular rods arranged between the partial conveyor belts and connected with one another by way of a frame, and a pivot drive having articulated rods which engage the frame in such a manner that the rectangular rods are pivotal about 90.degree. within spaces in the guide surface and between the partial conveyor belts.
Actuation of the device for turning the package is effected by means of a pivot drive 7 composed of articulated rods 8 and a pneumatic cylinder 9.
Conveyor belts 5 and 6 run in synchronism and are perpendicular to one another. The points of articulation 10 of the articulated rods can be selected at will; they must be adapted to one another in such a way that it is possible to perform a pivoting movement about a maximum angle of 90.degree.. According to the invention, the pivoting must here occur in such a manner that transporting surfaces 5 and 6 wh
