Description
Technical Field
The present utility model relates to a labelling machine for labelling containers.
Background
Such machines are well known from the prior art, in particular in the field of beverage industry, in different implementation variants. Labeling machines are generally equipped with a conveyor carousel by means of which containers to be labeled are conveyed through the machine.
In general, containers are transported at small distances from one another on a transport device of a container labeling machine, with a small (machine) indexing of the transport device. In particular, in labeling machines in which only every n containers transported on a transport carousel are labeled in relation to the number n of labeling stations, adjacent containers have a small distance from each other on the transport device, which labeling machines are operated with two or more labeling stations for high machine power or high throughput.
Labels to be applied to containers generally have a length which is greater than the spacing determined by the (machine) indexing of the conveyor, with two adjacent containers having the spacing relative to each other on the conveyor. This is often the case especially in wrap around labels, as the labels typically have a large length.
In the case of labels which are longer than the distance between two adjacent containers on the conveyor carousel, it is important to avoid the contact of a label which, although already fixed to a container, is not yet applied over its entire length to this container or in which the labelling process has not yet ended. This is especially true when the label is provided with an adhesive, as the label may adhere to the subsequent container when in contact with the container or may contaminate the container with adhesive.
In order to avoid such contact of the label with the subsequent container, a suction device is used in the prior art, which has a label guide provided with a suction opening and sucks a label section protruding from the container or not yet lying against the container onto the label guide. During the transport of the containers on the transport carousel (over a part of the transport path), the label sections are guided along the label guide by means of a suction device and kept away from the following containers. A labeling machine with such a suction device is disclosed, for example, in german patent document DE 20 2017 101 952 U1, where the suction device is referred to as a "vacuum plate".
The longer the label is used to label a container, the greater the probability that the label section of the label that typically extends from the container or has not yet been applied against the container will come into contact with a subsequent container.
Disclosure of Invention
The object of the present utility model is to provide a labeling machine in which, in particular when labels having a large label length are used, contact of the labels with subsequent containers can be reliably avoided.
This object is achieved according to the utility model by a labeling machine according to the utility model.
Preferred or advantageous further embodiments of the utility model are given in the further claims and in the following description. The features or combinations of features contained in the technical solution of the utility model are part of the description.
The labeling machine according to the utility model for labeling containers has a conveyor carousel for conveying containers, which is rotatably supported about a vertical rotation axis. The labeling machine according to the utility model also has a suction device for sucking (preferably by means of an adhesive, for example a hot glue) a label section of a label fixed to the container. The suction device comprises a label guide provided with a through-flow suction opening, which has a first end section, a second end section arranged downstream of the first end section in the conveying direction of the conveying carousel, and a middle section connecting the two end sections to each other. According to the utility model, the label guide is configured such that the label guide has a radial distance that varies with respect to the vertical axis of rotation over its entire extension from the first end section to the second end section.
The utility model is based on the knowledge that the label guide provides a longer path for the label section to be guided by its changing radial distance from the vertical axis of rotation than a label guide having a constant radial distance from the axis of rotation. The modified radial distance through the label guide reduces the effective length (i.e. the length in the conveying direction) of the label sections guided along the label guide compared to a label guide having a constant radial distance relative to the axis of rotation. The label section of the label attached to the container, which extends from the container or is not yet attached to the container, can thus be reliably held away from the subsequent container, said label section being sucked onto the label guide and guided along the label guide.
In the sense of the present utility model, a "tag section" is understood to be a partial section or portion of a tag.
The container to be labeled is preferably a beverage container, such as a bottle, in particular a glass or PET bottle or can.
The labeling machine may in particular be provided for labeling individual containers, i.e. containers which are not grouped and/or combined into groups or bundles of containers. For this purpose, the transport carousel may be equipped, for example, with container trays, which can each receive exactly one container. Furthermore, exactly one centering element, for example a centering bell, can be provided for each container disk in order to center or clamp the individual containers.
The maximum radial distance of the label guide with respect to the vertical rotation axis may be e.g. at least 5%, preferably at least 10% greater than the minimum radial distance of the label guide with respect to the vertical rotation axis.
In an advantageous manner, the labelling machine is configured for circumferential labelling of containers. That is to say, the labelling machine is preferably configured for providing the containers with a respective encircling label. Surrounding a label is understood here to mean a label which surrounds or surrounds the entire circumference of the container.
The labelling machine may in particular be a so-called roll labelling machine. In the labelling machine, the labels are provided in the form of a label tape wound into a roll, wherein individual labels are obtained by cutting the label tape.
In a preferred embodiment of the utility model, the label guide forms a wall of the suction device. The label guide may be configured, for example, as an at least sectionally arched or curved plate. It is furthermore preferred that the label guide is made of a rigid or inflexible material. Advantageously, the label guide is arranged such that the label guide is not deformed and/or crushed by the containers transported by means of the transport carousel.
Expediently, the labeling machine comprises a rotatably mounted vacuum drum for transporting the labels and for transferring the labels to the containers to be labeled. The suction device, in particular the label guide of the suction device, is advantageously arranged adjacent to the vacuum drum and behind the vacuum drum with respect to the conveying direction of the conveying carousel. By means of the described arrangement of the suction device, it is achieved that a label section of a label which is fixed to the container, which is extended from the container or which is not yet attached to the container, can be reliably sucked by the suction device after the label section is no longer held or sucked by the vacuum drum. Unlike the vacuum drum, the label guide of the suction device is expediently a rotatably mounted unit of the labeling machine.
In a preferred embodiment of the utility model, it is provided that the first end section of the label guide is at least partially arcuately configured and/or that the second end section of the label guide is at least partially arcuately configured. The radius of curvature of the arcuate portions of the respective end sections may be, for example, equal to the radius of the conveyor carousel.
According to an advantageous embodiment of the utility model, the middle section of the label guide is at least partially arc-shaped.
Furthermore, it may be provided that the first end section of the label guide has a constant radial distance from the vertical axis of rotation in the direction of conveyance of the conveyor carousel and/or that the second end section of the label guide has a constant radial distance from the vertical axis of rotation in the direction of conveyance of the conveyor carousel. In this case, the radial distance of the first end section from the vertical rotation axis and/or the radial distance of the second end section from the vertical rotation axis is preferably equal or substantially equal to the radius of the conveyor carousel.
The expression "equal or substantially equal" to the radial distance of the first end section or the second end section to the radius of the conveyor carousel is thus understood to mean that the radial distance of the first end section or the second end section with respect to the vertical rotation axis is smaller or larger than the radius of the conveyor carousel by at most 10%, preferably at most 5%.
In particular, it can be provided that the first end section of the label guide has the same radial distance from the vertical axis of rotation as the second end section of the label guide. In an alternative embodiment of the utility model, the first end section of the label guide has a different radial spacing, in particular a greater radial spacing, relative to the vertical axis of rotation than the second end section of the label guide.
In a preferred embodiment of the utility model, the intermediate section of the label guide has a radial distance along the conveying direction of the conveying carousel that varies with respect to the vertical axis of rotation.
Advantageously, the intermediate section of the label guide has a larger maximum radial distance relative to the vertical axis of rotation than the first end section and/or the second end section of the label guide. In this way, the distance between the label section guided on the label guide and the subsequent container is increased when the label section moves along the intermediate section, so that contact of the label section with the subsequent container can be reliably prevented.
At least a part of the intermediate section of the label guide may have a concave shape, viewed from the vertical axis of rotation. Alternatively or additionally, at least a part of the middle section of the label guide may have a convex shape, seen from the vertical rotation axis.
In an advantageous further development of the utility model, the label guide, in particular the middle section of the label guide, is at least partially wave-shaped. The wavy configuration of the intermediate section makes it possible to reduce the effective length of the labels guided along the label guide particularly strongly at low cost.
The two end sections of the label guide and the middle section of the label guide are preferably constructed integrally with one another. This allows for low-cost assembly of the label guide in the labeling machine.
In an advantageous manner, the suction device comprises at least one under-pressure generating unit, in particular a vacuum pump, for generating an under-pressure at the label guide.
Advantageously, the label guide is a form factor. It is furthermore advantageous if the suction device has one or more further, format-independent parts, wherein the label guide can be replaced independently of the format-independent parts of the suction device. In this way, the replacement of the format-independent parts of the suction device can be dispensed with during format changes, so that at least the format changes of the suction device are limited to the replacement of the label guide and possible further format parts of the suction device. In this way, the replacement specification can be realized with little effort and effort. The above-described underpressure-generating unit is preferably a specification-independent part of the suction device, so that the underpressure-generating unit advantageously does not have to be replaced when changing specifications.
In the sense of the present utility model, a format is understood to be a component of a labeling machine whose shape and/or size is adapted to the size of the container to be labeled and/or to the size of the label used to label the container. That is, the format is a component of the labeling machine that is replaced when changing the size of the container to be labeled and/or changing the size of the label for labeling. Accordingly, a specification-independent part is understood to be a component of the labeling machine whose shape and/or size is independent of the size of the container to be labeled and/or of the label used for labeling.
Preferably, the suction device is an integral part of the labelling station of the labelling machine. The labeling machine can have a plurality of labeling stations, each having a suction device of the aforementioned type, which can be configured in particular identically to one another.
In the case of a labeling machine having a plurality of labeling stations, a corresponding labeling station can be provided for labeling only n containers transported on the transport carousel, wherein n is the number of labeling stations of the labeling machine. If the labelling machine has, for example, two labelling stations (i.e., n=2), the respective labelling stations are expediently provided for labelling only every two containers which are transported in the transport device.
The preferred or advantageous configurations of the utility model described so far contain features which are described in each case in part in several combinations. However, the features can expediently also be investigated individually and in a meaningful further combination. In particular, the features can be combined with the labeling machine according to the utility model individually and in any suitable combination.
The foregoing features, and advantages of the utility model, as well as the manner and method of attaining them, will be more apparent and may be better understood in conjunction with the following description of embodiments of the utility model. The examples are presented to illustrate the utility model and the utility model is not limited to the combination of features presented therein nor to the functional features. Furthermore, features of each embodiment that are suitable for this may also be specifically considered as being introduced into the further embodiments separately to supplement the embodiments and/or in combination with any of the techniques.

Detailed Description
Fig. 1 shows schematically a labelling machine 1 for circumferential labelling of containers 2 from a top view. The container 2 is in this embodiment a beverage container, such as a bottle or a can.
Labelling machine 1 comprises a conveyor carousel 3 which is rotatably supported about a vertical rotation axis 4. Containers 2 to be labeled are transported to transport carousel 3 by a not-shown input star of labeling machine 1. The containers 2 to be labeled are transported equidistant from one another by means of the transport carousel 3 along a part-circular path in the transport direction 5 of the transport carousel 3. After the containers 2 to be labeled have been labeled in the labeling machine 1, the containers 2 are output from the conveyor carousel 3 by means of an output star of the labeling machine 1, not shown.
For transporting the containers 2, the transport carousel 3 has a plurality of container disks, not shown, which are each rotatably supported about a vertical axis and on which one container 2 can be positioned. Preferably, labelling machine 1 comprises for each container disk an own drive unit, in particular an own servomotor, for driving the respective container disk and a control device for controlling the drive unit. The individual container disks can thus be rotated independently of one another, and the respective rotational speeds of the container disks are set independently of the rotational speed of the conveyor carousel 3. Advantageously, the individual defined movement sequences of the container disk and also the time sequence of the defined movement sequences or the time coordination of the defined movement sequences are stored in the control device or in a data memory which is communicatively connected to the control device. The control device advantageously controls the individual drive units in accordance with a stored defined course of motion.
Labelling machine 1 also comprises a labelling station 6. The labelling station comprises a label feed device, not shown, for unwinding a label tape wound into a roll, a cutting device, not shown, for cutting the label tape into individual labels 7, and a rotatably supported vacuum drum 8 for transporting the labels 7 and transferring the labels 7 onto the containers 2. The labelling station 6 also comprises rollers, not shown, for applying adhesive to the labels 7. The labelling station 6 also comprises a brushing unit 9 and suction means 10.
The suction device 10 comprises a base body 11 having a cavity, a label guide 12 provided with a through-flow-capable suction opening, and an under-pressure generating unit 13 for generating an under-pressure at the label guide 12, which is arranged on the base body 11 and delimits the cavity of the base body 11. The underpressure-generating unit 13 can be configured, for example, as a vacuum pump connected to the base body 11 of the suction device 10 for evacuating the cavity of the base body 11.
The label guide 12 of the suction device 10 comprises a first end section 14, which is arranged on a first end of the label guide 12. The label guide 12 further comprises a second end section 15 atThe conveying direction 5 of the conveying carousel 3 is arranged downstream of the first end section 14 and at the second end of the label guide 12. The label guide 12 further comprises a middle section 16 arranged between the two end sections 14, 15 and adjoining the two end sections 14, 15. The end sections 14, 15 and the intermediate section 16 of the label guide 12 are integrally formed with one another. The label guide 12 has a radial distance d which varies with respect to the vertical rotation axis 4 over its entire extension from the first end section 14 to the second end section 15 R 。
The two end sections 14, 15 of the label guide 12 are configured in an arc-shaped manner and have a constant radial distance d relative to the vertical rotational axis 4 along the conveying direction 5 of the conveying carousel 3 R . The bending radius of the two end sections 14, 15 is substantially equal to the radius R of the conveyor carousel 3. In the present exemplary embodiment, the first end section 14 has a shorter extension than the second end section 15 in the conveying direction 5 of the conveying carousel 3. However, this need not be mandatory. In principle, the first end section 14 may have a longer extension than the second end section 15 in the conveying direction 5 of the conveying carousel 3, or the extension of the first end section 14 in the conveying direction 5 of the conveying carousel 3 may be just as large as the extension of the second end section 15 in the conveying direction 5 of the conveying carousel 3.
The intermediate section 16 has a concave shape as seen from the vertical axis of rotation 4. Unlike the two end sections 14, 15 of the label guide 12, the middle section 16 of the label guide 12 has a radial distance d which varies with respect to the vertical axis of rotation 4 along the conveying direction 5 of the conveying carousel 3 R Wherein the intermediate section 16 has a larger maximum radial distance d from the vertical rotational axis 4 than the two end sections 14, 15 R . At the transition from the first end section 14 to the intermediate section 16, the radial distance d of the label guide 12 relative to the vertical rotation axis 4 is provided R Increases the radial distance d of the label guide 12 from the vertical rotation axis 4 R At the transition from the intermediate section 16 to the second end section 15.
The label guide 12 of the suction device 10 is a gauge of the suction device 10. The base body 11 or at least a part of the base body 11 can, if appropriate, likewise be a specification of the suction device 10. And the aforementioned under-pressure generating unit 13 of the suction device 10 is a specification-independent part of the suction device 10. Therefore, the undervoltage generating unit 13 is not replaced at the time of replacing the specification, whereby the replacement specification can be realized at low cost.
An under-pressure is generated by the vacuum drum 8 of the labelling station 6 to hold the labels 7 provided by the label feeding means (not shown). The vacuum drum 8 rotates counter to the transport direction 5 of the transport carousel 3 and transports the labels 7 together. During the laying of the labels 7 on the vacuum drum 8, an adhesive, in particular a hot glue, is applied onto the rear face of the labels 7 by means of the aforementioned (not shown) rollers of the labelling station 6, wherein the adhesive is preferably not applied onto the entire rear face of the labels 7, but only onto the vertically extending first end and the vertically extending second end of the labels 7.
The label 7 is transferred by the vacuum drum 8 onto the container 2 to be labelled, which passes the vacuum drum 8, wherein the label 7 is attached with its first end provided with adhesive to the container 2. In order to wind the labels 7 onto the containers 2, the containers 2 are rotated on a container tray, on which the containers 2 are positioned, about their longitudinal axis during their transport in the transport direction 5 (at least over a part of the transport path).
In order to prevent the label section 17 of the label 7, which has not yet been applied to the container 2 or has not yet been wound around the container 2 before the winding process has ended, from coming into contact with the subsequent container 2 and the label 7 possibly adhering with its second end provided with adhesive to the subsequent container 2, the label section 17 is sucked by the suction device 10 onto the label guide 12 of said suction device. This not only prevents the label section 17 of the label 7 which has not yet been applied to the container 2 from contacting the subsequent container 2, but also ensures that the label 7 is stretched and guided when wound around.
During the transport of the containers 2 in the transport direction 5, the label sections 17 which have not yet been applied to the containers 2 slide along the label guide 12, wherein the label sections 17 are wound onto the containers 2 on the basis of the aforementioned rotation of the containers 2 about their longitudinal axes and thereby become continuously shorter.
By means of the changing radial distance R of the label guide 12 relative to the axis of rotation 4, the effective length L of the label section 17 is reduced compared to a label guide with a constant radial distance eff . The probability of the label section 17 coming into contact with the subsequent container 2 can thereby be reduced in the case of labels 7 having a large (actual) label length.
If the container 2 reaches the brushing unit 9, the label section 17 which has not yet been applied to the container 2 is detached from the label guide 12, wherein the label section 17 which has not yet been applied to the container 2 is already so short that it cannot come into contact with a subsequent container 2. The label 7 is pressed against the container 2 by the brushing unit 9 so that the second end of the label 7 provided with adhesive is attached with its back side to the front side of the first end of the label 7. During the movement of the container 2 along the brushing unit 9 in the conveying direction 5, the container 2 continues to rotate about its longitudinal axis.
In addition to the elements described above, labelling machine 1 is preferably equipped with further elements, such as an input screw, a centering cap, one or more gratings, etc., whose purpose and operation are known in principle to the person skilled in the art, so that the drawing description thereof is omitted for reasons of better simplicity.
The following description of the embodiment from fig. 2 is mainly limited to the differences from the previously described embodiment described in connection with fig. 1, to which reference is made in respect of the same features and functions. Identical and/or corresponding elements are denoted by the same reference numerals as long as they are suitable. Hereinafter, the non-illustrated features of the foregoing embodiments are referenced in the other embodiments without describing the non-illustrated features again.
Fig. 2 shows a further labelling machine 18, which is schematically used for circumferential labelling of containers 2, from above.
The labelling machine 18 likewise comprises a conveyor carousel 3 and a labelling station 6 with a suction device 10 having a label guide 12 with a first endA partial section 14, a second end section arranged downstream of the first end section 14 in the conveying direction 5 of the conveying carousel 3, and a middle section 16. In this labeling machine 18 too, the label guide 12 has a radial distance d which varies with respect to the vertical axis of rotation 4 over its entire extension from the first end section 14 to the second end section 15 R The conveyor carousel 3 is rotatably supported about said vertical rotation axis.
In the embodiment from fig. 2, the label guide 12 is configured in a wave-like manner. That is, the label guide 12 has a convex shape and a concave shape alternately as viewed from the vertical rotation axis 4. Maximum radial distance d of label guide 12 relative to vertical rotation axis 4 R Larger than the radius R of the carrousel 3, while the minimum radial distance d of the label guide 12 with respect to the vertical rotation axis 4 R Equal to the radius R of the conveyor carousel 3.
In the present exemplary embodiment, the label guide 12 is configured in a wave-like manner over its entire length. In an alternative embodiment, the label guide 12 may be configured in a wave-like manner only over a portion of its length, for example only over its intermediate section 16.
In each of the two preceding embodiments, the respective labelling machine may have, in addition to its already described or illustrated labelling station 6, one or more further, not illustrated labelling stations which are in particular structurally identical to the already described or illustrated labelling station 6. In this case, the respective labelling stations are preferably provided for labelling only every n containers transported on the transport carousel 3, where n is the number of labelling stations of the labelling machine.
Fig. 3 shows an axis chart, wherein the ordinate of the chart represents the throughput P of the labelling machine for labelling containers (i.e. the number of containers per time unit) and the abscissa of the chart represents the length L of the label for labelling containers.
At a first length L 1 And a second greater length L 2 Within the length interval there between, the throughput of the labelling machine according to the utility model, in particular of the embodiment according to fig. 1 or 2 (shown in solid lines), and the throughput of the labelling machine from the prior art (shown in broken lines) are reflected by way of example in relation to the length L of the label.
In the following, it is assumed that the labeling machine according to the utility model differs from the labeling machines from the prior art only in that the label guides of the suction device in the latter labeling machine have a constant radial distance from the vertical axis of rotation, whereas the label guides of the suction device in the labeling machine according to the utility model have a variable radial distance from the vertical axis of rotation.
Not only the labeling machine according to the utility model but also the labeling machines from the prior art can be used with a small label length at a certain throughput P 0 And (5) running. If the length L of the label increases beyond a predefined threshold value, the throughput P must be reduced with the increasing length L of the label both in the labeling machines from the prior art and in the labeling machines according to the utility model, in order to be able to reliably prevent label sections of the label attached to the container that are not yet attached to the container from coming into contact with subsequent containers.
For labelling machines from the prior art, the threshold value is at a certain length L X Is a kind of medium. Since the effective length of the label sections that have not yet been wound is reduced in the labeling machine according to the utility model by the changing radial distance of the label guide relative to the vertical axis of rotation (see fig. 1), the threshold value is at a greater length L for the labeling machine according to the utility model Y Is a kind of medium. In other words, the labeling machine according to the utility model can be operated at a high throughput up to a greater label length than labeling machines from the prior art. Or in other words, it is sufficient in the labelling machine according to the utility model to reduce the throughput P only with a greater label length.
