1. Technical Field
This application relates to a labeling machine and method for labeling containers, such as bottles or cans, especially sardine cans. Such cans are usually longer than they are high or wide, and thus utilize labels that are longer than they are wide, i.e. have a ribbon-like shape. Since such labels are relatively much longer than they are wide, it is advantageous to guide and align the labels throughout the process of affixing the labels to the cans in order to promote optimum alignment and centering on the exterior surface of the cans.
This application further relates to a labeling machine for containers such as cans, bottles and similar containers, comprising transport means for the containers, a rotating carrier with a plurality of turntables that are supported on them so that they can be driven in rotation and/or oscillation, for the supportive and centering holding of the containers with docking stations that are located in a stationary manner on the peripheral edge of the rotating carrier, and specifically at least one gluing station, a label storage station with a label magazine and a label transfer station with transfer elements, whereby the gluing station is formed of a rotating glue roller, a glue application mechanism and/or a glue spray station that can be turned on and off.
2. Background Information
Labeling machines of this type are known in a variety of models, in particular in the form of rotary or linear machines. DE-OS 84 15 528 discloses a labeling machine with a gluing and application device that holds and guides the labels, upstream of which is a magazine of individual labels with a label extractor that is located on its front side. This individual label magazine is realized in the form of a pneumatic device that uses a vacuum and can be pivoted around a vertical axis. The label extractor also has a crank drive, with which, in addition to the pivoting movement, a transfer movement for the extracted labels to a gluing device can be executed parallel to the front side of the label magazine. The further transport of the labels takes place by means of conveyor belts. DE-AS 1 102 640 and DE-GM 1 941 274 disclose gripper cylinders for the transfer of the labels to circulating glue pallets, in which the extraction and holding of the labels is accomplished either by suction nozzles in connection with mechanically acting gripper fingers or by suction nozzles alone. The labels are thereby transferred to a container by the rolling motion of the glue pallet along the rotating cylindrical surface of the container.
These systems of the prior art are preferably used to transfer standard mass-produced labels that have approximately equal height and width ratios into the labeling area. If, on the other hand, the process calls for labels in strip form that have a large ratio between the height of the label and the length of the label, these systems of the prior art cannot be used successfully.
In one method of the prior art for the handling of bands or strips in connection with their application to packages, the bands or strips are extracted individually and one after another from the stack of bands or strips, and are transported along a track that is in the shape of a circular arc and then guided along a straight-line track until they are transferred to a package that is being transported at a right angle to said track. The device required to perform this action is equipped with a band pick-up device which has a plurality of banderole carriers rotating in circulation, by means of which the bands or strips are transferred to a straight-line endless conveyor with suction strips. From there, the bands or strips are conducted to a transfer station, where they are kept ready and transferred to packages that are being transported in a transverse direction. The suction strips used are thereby used only for the transport of the bands or strips that are being processed. Suction strips of this type are not suited for labeling using labels that have a very ratio of height to width. Labels of this type have only an extremely low inherent stability and consequently cannot be processed and applied with the required level of quality using the systems described in the prior art.
Taking into consideration the disadvantages of the systems of the prior art described above, the object of one possible embodiment of the invention is to overcome said disadvantages and to create a device with which strip-shaped labels of the type described above, for example, can be processed easily. In particular, for the labeling of containers that are not rotationally symmetrical, at least one possible embodiment teaches a technically supported forced guidance in the zones in which otherwise it is impossible to prevent the breakout of unstable labels or strip labels.
At least one possible embodiment teaches that this object can be accomplished by a labeling device of the type described herein, whereby a first stationary and vacuum-assisted guide device that is associated with the end surface of the label magazine is provided, and at least one second vacuum-assisted guide device that is associated with each turntable and rotates with said turntables around the longitudinal axis of the machine for the controlled forced guidance of the labels to be applied.
At least one possible embodiment teaches that the label is extracted from the label magazine after a preceding initial gluing of the container, and by the container, whereby the label extracted in this manner is extracted from the label magazine along a first, stationary guide device in a sliding motion, and by the continued rotation of the container with the turntable and as a result of its simultaneous rotation around the longitudinal axis of the machine, and at least after the completed initial gluing is taken over and steered by a second guide device and guided in a sliding movement over its remaining length.
With the solution claimed by at least one possible embodiment, a preferably vacuum-assisted controlled forced guidance of the label is provided for the label from its extraction from the label magazine until its application and final labeling. This arrangement has the advantage, among other things, that at the end of the application process, the otherwise conventional overlap tolerances are significantly smaller.
Additional features of at least one possible embodiment of the invention are described in greater detail below on the basis of preferred examples. The features that are described and/or illustrated are the object of at least one possible embodiment, both individually and/or in any possible combination.
The above-discussed embodiments of the present invention will be described further hereinbelow. When the word “invention” or “embodiment of the invention” is used in this specification, the word “invention” or “embodiment of the invention” includes “inventions” or “embodiments of the invention”, that is the plural of “invention” or “embodiment of the invention”. By stating “invention” or “embodiment of the invention”, the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
At least one possible embodiment is explained in greater detail below on the basis of the exemplary embodiment illustrated in the accompanying drawings, in which:
In a canning process, the product is of course first placed in the cans by any one of a number of methods, depending on the product to be canned. Next, the filled cans are closed and/or sealed shut. The closed cans are then heated to a desired temperature to cook and/or sterilize the contents to prevent contamination. If the cans are not finally sealed after the cooking step, a final sealing can be performed after the cooking, in at least one possible embodiment. The closed, filled cans are then cleaned to remove any contaminants or product residue off the exterior of the cans. The cleaned cans are then labeled by a labeling machine, such as described herein.
As shown in
These turntables are driven by means of rotation gear trains that are located underneath the carrier 4, as described by EP 1 052 176 A1, for example, and the content of which, to the extent that it contributes to the explanation of at least one possible embodiment, is hereby incorporated by reference into this description. On the peripheral edge of the rotating carrier 4 there are docking or screw-on stations such as the gluing station 6 with a glue roller 7, spray or injection gluing mechanisms 8, 9, 10 and a labeling station with a label magazine 11. In connection with the label magazine 11 there is a first guide device 12 which is located on an end surface. This guide device is stationary and is held in the area of the label magazine so that it can be adjusted relatively multi-dimensionally with reference to the length to be processed and the required guidance and sliding motion of such a label 13. Effectively connected with said guide device 12 is a second, vacuum-assisted guide device 14 which is associated laterally with each turntable 5 and circulates with the latter around a longitudinal axis 15 of the machine. This second guide device is for the forced guidance of a label 13 to be applied during almost the entire labeling process, and in particular after the end 16 of each label 13 has traversed and exited the area of the first guide device 12, as will be explained in greater detail below.
This second guide device is held on the carrier 4 so that it can be adjusted vertically around an axis 17. In particular in the inlet and outlet area 2, in which the guide curves (which are not shown in any further detail) are provided to guide the entry and exit of the containers 1, the second guide device 14 can be moved outside its actual working height, preferably upward, so that it can be lowered again after it traverses this area. For this purpose, in the exemplary embodiment, a control curve 18 with a cam roller 19 is provided. Depending on the type of the initial gluing 8, the guide device can also be moved accordingly in this area to prevent contamination and similar phenomena. In addition, the guide device 14, like the guide device 12 in the appropriate configuration, has top and bottom guides 20 to fix the height of the label as it slides along.

According to one possible embodiment, the labeling machine shown in
The labeling machine shown in
The labeling process, according to at least one possible embodiment, begins with the cans 1 being transferred by an input apparatus onto the turntables 5 of the carrier 4. The carrier 4 rotates, as seen in
Glue or other adhesive is first applied to a can 1 at the gluing station 6 by the roller 7 and/or the spray devices 8, 9. The can 1 is rotated by the turntable 5 to permit application of glue to a substantial portion of the outer side surface of the can 1. The turntable 5 rotates the can 1 into a position such that the area 22 of the can 1 that projects beyond the flat edge or surface 21 of the turntable 5 comes into contact with the beginning or end portion 23 of a label 13. By the adhesion of the glue and the pulling forces exerted by the clockwise rotation of the turntable 5 and by the counterclockwise movement of the carrier 4, which moves the turntable 5 away from the label magazine 11, the label 13 is extracted and applied to the can 1.
To minimize or substantially prevent misalignment of the label 13 on the can 1, two vacuum-assisted guide devices 12 and 14 are utilized to guide and align the label 13. The first guide device 12 guides the labels 13 as they leave the magazine 11. The second guide device 14, as can be seen in
After the majority of the label 13 has been applied to the can 1, the spray gluing mechanism 28 sprays an adhesive or glue onto the can 1 and label 13 at the point where the ends of the label 13 overlap to finally and securely affix the label 13 to the can 1.
