DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a device for handling containers, e.g., cans made of glass, plastic, wood or metal, or bottles of glass or plastic, wherein the containers with the aid of a conveyor are conveyed in lying position past a detector in order to inspect characteristic data about the containers, and means which, on the basis of such data, determines how the containers are to be handled subsequently, e.g., sorted for removal from the conveyor, or conveyed further to the downstream end of the conveyor, and wherein the conveyor has first and second rotatory roller units, a first driving motor being connected to a first of the roller units to cause rotation thereof about its axis of rotation and thereby rotation of the second roller unit about its axis of rotation, by movement of belts or bands which extend continuously about and between the roller units. When inserted into the apparatus, such containers are preferably empty and may have served as storage for foodstuffs, e.g., beverages, or other usable contents.
It has previously been known to use controllable pushers which operate transverse to the conveyor belt, so that the containers are pushed off the belt and onto a second conveyor or directly into a receptacle means. A solution of this kind is technically complex, requires a great deal of equipment and is not suitable for handling all types of containers.
There has therefore long been a desire to provide a simple sorting device, especially for the cases where there is a need for sorting out to two or three exits.
SUMMARY OF THE INVENTION
According to the invention, the device is characterised in: run in grooves on the roller units; provided respectively a first and a second rotatable roll, wherein the rolls can be made to rotate with the aid of respective first and second roll driving motors about their longitudinal axis in the same direction of rotation, and wherein the rolls on coordinated movement are moveable in the horizontal and optionally in the vertical direction relative to the conveyor, whereby the rolls are displaceable to a first position wherein they lie substantially laterally outward relative to the container transport path of the conveyor and are spaced apart at a first distance, a second position wherein they are located above the conveyor and displaced towards each other so as to be spaced apart at a second distance which is smaller than the width of the conveyor, and a third position wherein the rolls are spaced apart at a third distance which is smaller than or equal to said second distance; conveyor; and sideways displacer for the containers, wherein the displacer consists of a laterally displaceable suspension on which is secured a substantially downward directed pair of plates, wherein the plates are spaced apart at a distance at least equal to the width of the conveyor.
According to further embodiments of the device, the rolls are mounted on a pair of arms which, when the rolls above the conveyor are positioned so as to be spaced apart at second distance with the aid of a motor-driven arm rotation mechanism, lift the container up from the conveyor and, on rotation of the rolls, cause the container to rotate about its longitudinal axis, so that a bar code located on the container can be read by the bar code reader.
Each of the roller units is preferably made having a double-cone configuration, a so-called "diabolo" shape.
The rolls are preferably driven by respective internally mounted motors.
Furthermore it would be advantageous to allow said belts or bands to have a circular, rectangular, triangular or polygonal cross-section.
In a special and preferred embodiment, the device can be a part of a transport path for containers in a reverse vending apparatus. Data concerning the shape and/or colour and/or material type of the container will in this case be registered by the reverse vending apparatus upstream in the transport path in relation to the conveyor of the device.
The said data concerning the container and its bar code data are supp
