Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) For the sake of example, the figures show:

(2) FIGS. 1-6 schematically, the sorting of beverage containers by means of the apparatus according to the invention, wherein the repositioning of the containers by means of two containers is shown by way of example.

DETAILED DESCRIPTION

(3) FIG. 1 shows a first exemplary state during a method for sorting containers with the apparatus 1 according to the disclosure. Optical characteristics of the containers 2, 4 are continuously detected by the identification device 8 and evaluated by an evaluation device. The detected characteristic is preferably the decor of the respective container 2, 4. Preferably, the containers 2, 4 are bottles or cans, in particular, for the holding beverages.

(4) The identification device 8, in particular the evaluation device, generates data for controlling the transport device 50 so that shifting means 14 are moved along the continuous track 12 in such a way that they move at least in the transport direction T at the same speed as the containers 2, 4 transported on the conveyor belt 6. The shifting means 14 can be coupled with the transport device 50 by means of magnetic couplings 70, shown in FIG. 4. The apparatus 1 preferably forms a crossover 22, by means of which the transport paths are portionally separated from each other.

(5) Furthermore, during the progression of the main transport path and/or during the progression of the secondary transport path, one separator device 24 or one for each can be arranged. The separator device preferably comprises a means for shifting or repositioning the containers. Here, the means for shifting or repositioning is preferably a compressed-air device or a mechanical element, such as a slider for example. This separator device 24 removes containers conveyed on one of the transport paths from the transport path. Preferably, by means of the separator device 24, separated containers 2a are supplied to a pick-up device 26 or another transport path.

(6) Furthermore, FIG. 1 shows that the shifting means 14.1 has already been moved and the container 4.1 is adjacent. The shifting means 14.2 is also already adjacent to the container 4.2. Between the two containers 4.1 and 4.2, by way of pure example, a further container 2 is arranged, which is not repositioned. However, it may also be that a plurality of containers 4 are arranged directly one after the other on the conveyor belt 6. Furthermore, it is conceivable that a multitude, more preferably, exactly two or more than two containers 2, are arranged between two containers 4.

(7) FIG. 2 shows that the shifting means 14.1 is already been deflected in an inclined manner towards the transport direction T, in particular, being orthogonally to it, and has thus come into contact with the container 4.1, whereby this is also deflected. In accordance with this illustration, the container 4.2 has not yet been shifted. Preferably, the deflection of the shifting means 14 in the direction N is carried out exclusively in the selection region 16.

(8) FIG. 3 shows that both shifting means 14.1 and 14.2 move the respective containers 4.1 and 4.2 in the direction transversely to the conveyor direction of conveyor belt 6. Preferably, the shifting means 14 move the containers from a first conveyor belt 6 to a second conveyor belt 61. The first conveyor belt 6 preferably moves along the main transport path 18 and the second conveyor belt 61 preferably moves along the secondary transport path 20. Preferably, these conveyor belts always move at the same speed, in particular, in the selection region 16. The shifting movement of the shifting means 14 is preferably effectuated by means of actuators. Preferably, each shifting means 14 comprises such an actuator, in particular, a lifting element or shifting element.

(9) FIG. 4 shows that the container 4.1 has been conveyed to the secondary transport path 20 and the shifting element 14.1 is spaced away from the container 4.1. The shifting element 14.1 thereby moves back again. In accordance with this illustration, the second container 4.2 has already arrived at the secondary transport path 20, therefore, also the second shifting means 14.2 moves back into the initial position.

(10) FIGS. 5 and 6 show that containers 4.1 and 4.2 are moved independently of the shifting means 14.1 and 14.2. The shifting means 14.1 and 14.2 are also in the initial configuration again, meaning not shifted and are moved across the continuous track 12 for further use back into the initial position or move back to the initial position along the continuous track 12 for further use.

(11) Referring to FIG. 1, a vacuum device 60 may be provided for the aspiration of the individual containers 2,4 onto the conveyor belt 6, wherein the individual containers can be aspired by means of vacuum onto the conveyor belt at least portionally along the main transport path and preferably portionally along the secondary transport path. Furthermore, referring to FIG. 4, each shifting means 14.1, 14.2 may comprise at least one holding means 90, such as an aspiration means 80, for stable movement of the respective container.

(12) The present disclosure therefore preferably refers to a sorting device 1 for sorting containers 2, 4, in particular, beverage containers. This apparatus 1 preferably comprises a conveyor belt 6 for transporting a multitude of container units 2, 4, an identification device 8 for identifying a decor on each container unit 2, 4 conveyed on the conveyor belt, wherein, by means of the identification device 8, selection data can be generated depending on the decor present on a specifically detected container 4, and a selection device 10 for repositioning individual container units 4 on the conveyor belt 6 depending on the respectively identified decor, wherein the selection device 10 forms a continuous track 12 and has shifting means 14 for shifting the identified container units 4, wherein the continuous track 12 extends along the conveyor belt 6 in a selection region 16, wherein the individual shifting means 14 in the selection region 16 can be accelerated to the same speed as the conveyor belt 6 by means of a transport device and thereby, a specific and previously identified container unit 4 is adjacent, whereby the control system of the transport unit is carried out depending on the selection data, wherein the respective shifting means 14 for shifting the adjacent container unit 4 can be shifted in a direction N inclined towards the transport direction T of the conveyor belt 6.

(13) This disclosure is favorable since, for example, identical beverage containers, such as cans or bottles, can be provided with different decor until shortly before completion, in particular, of filling or empty packaging, and can be guided across the same handling path together, particularly if different apparatuses for decor application are used. A significant reduction in complexity can therefore be effectuated since the handling path in the plant does not have to be alternately used for one or the other type of container. Thus, all containers can also be conveyed at the same time, whereby the total flow of the plant is increased, wherein an emptying of the system is not required even when changing individual apparatuses for decor application.
