(11) The feed device 2 consists of two conveyor belts 2.1 and 2.2, which are embodied as endless belts and which are arranged so as to be aligned with one another in transport direction X. The two conveyor belts 2.1 and 2.2 are arranged at a distance from one another, so that a gap 7 is embodied between them. In the illustration in
(12) The printing device 3 is illustrated in detail in
(13) In particular in the case that the labels 5 are removably applied (adhered) to a carrier strip 4, the label dispensing unit 3.1. has a label dispensing edge 3.11, at which the carrier strip 4 is diverted to such an extent that the relatively stiff label 5 detaches from the carrier strip 4 at that location and is moved further in the dispensing direction S, while the carrier strip 4 is diverted/moved in a different direction, in
(14) As stated, the case that the labels 5 are not applied to a carrier strip 4, but are obtained by severing a partial section, which forms the respective label 5, from a material strip 4, is also possible. For this purpose, the label dispensing unit 3.1 can have a severing device (not illustrated), comprising severing means, in particular comprising a cutting wire, a blade or a knife, by means of which said partial section is severed from the other material strip so as to form the label.
(15) After dispensing or already during dispensing from the label dispensing unit 3.1, respectively, the printed label 5 is transferred to a manipulator means 6.1 of the application device 6 or comes in contact therewith, respectively, which will be explained in more detail below.
(16) The application device 6 has a manipulator means 6.1 for moving the printed label 5 from a pick-up position I (inside the device), in which the printed label is transferred from the label dispensing unit 3.1 to the manipulator means 6.1 in the dispensing direction S, to a dispensing position II (inside the device), in which the manipulator means 6.1 can apply the printed label 5 to the package 1. For the exemplary embodiments in
(17) As shown in
(18) According to the first embodiment (
(19) According to the first embodiment of the device according to the invention, as is shown by
(20) As can be seen when comparing
(21) As already suggested above, the manipulator means 6.1 is configured in such a manner that the label 5 can adhere to the element or endless belt 6.11, respectively. For this purpose, the manipulator means 6.1 has a means, which is not illustrated in detail here, for generating a underpressure, for example a suction device, which suctions the label 5 and thus presses it against the element or endless belt 6.11, respectivelythe label 5 adheres automatically.
(22) As is shown in
(23) As is furthermore shown in
(24) The element or endless belt 6.11, respectively, is connected to a clocked drive, which is not illustrated in detail here, which effects the circulating movement of the element 6.11. The stroke length (interval length), which the drive provides, corresponds to the horizontal distance between the pick-up position I and the dispensing position II. When the endless belt 6.11 is stopped, the printed label 5 can thus be dispensed from the label dispensing unit 3.1, whereby is adheres to the endless belt 6.11 in the pick-up position I. In the case of the first embodiment, the manipulator means 6.1 can subsequently be pivoted into the second position B, which is illustrated in
(25) To be able to carry out the motion sequences, which are described above and which are illustrated in
(26) As mentioned above, an alternative second embodiment is also possible in addition to the above-described first embodiment of the device according to the invention, which is illustrated in
(27) In the case of this alternative second embodiment, the device has a control device, which is not illustrated in detail here, which controls the pivot movement of the manipulator means 6.2 and the circulating movement of the element or endless belt 6.11, respectively, in such a manner that the circulating movement of the element 6.11 is stopped (the label 5 is located in the pick-up position I; the manipulator means 6.1 is located in position A), when the element 5 is transferred from the label dispensing unit 3.1 to the element 6.11, the manipulator means 6.1 is pivoted from the first position A into the second position B (the label 5 is then located in the first transport position T), after the label 5 has been transferred to the element 6.11, the manipulator means 6.1 is pivoted back into the first position A after the second position B has been reached, wherein the circulating movement of the element 6.11 is carried out for the duration of a stroke (interval), wherein the stroke length (interval length) of the movement corresponds to the horizontal distance between pick-up position I and dispensing position II (the label 5 is then located in the second transport position T), and the manipulator means 6.1 is then moved from the first position A into the second position B (the label 5 is now in the dispensing position II).
(28) As can be seen when comparing
(29) A method for labeling individual packages 1 can be carried out by means of the device described above by means of
(30) wherein the manipulator means 6.1 applies the label 5 to the package 1 at the dispensing position II, while a further printed label 5 is simultaneously arranged on the manipulator means 6.1 in the pick-up position I or in one of the transport positions T.
(31) As stated, the manipulator means 6.1 is pivoted from a first position A into a second position after the respective label 5 has been transferred to the manipulator means 6.1 and in particular to the endless belt 6.11 at the pick-up position I, the label 5 is then moved across a distance, which corresponds to the horizontal distance between the pick-up position I and the dispensing position II, the manipulator means 6.1 is then pivoted from the second position B back into the first position A and the label 5 is finally applied to the package 1. In this case, provision is made for a further label 5 to be transferred to the manipulator means 6.1 at the pick-up position I after the manipulator means 6.1 has been pivoted from the second position B back into the first position A.
