Description

Labeling device for containers

The present invention relates to a labeling device for containers, such as bottles, with a cutting device according to the preamble of claim 1.

State of the art

Labeling devices for containers, such as bottles, cans or the like, are sufficiently known from the prior art. These labeling devices can be designed as rotary machines with a carousel, on the periphery of which containers are guided in container receptacles, or as linear machines in which the containers are guided along a linear transport path past suitable labeling units. Labeling devices usually comprise labeling units or other devices with which the labels are applied to the containers. For this purpose, the labeling devices comprise a series of rotatably mounted cylinders which take labels from a source and, if necessary, cut and glue them and transfer them to the containers.

When processing non-adhesive labels that are arranged on a label tape or are provided in the form of a label tape, it is necessary to insert a new label tape into the labeling device after use of a label tape. Until the labeling device is set to the new label tape, some labels are usually used for test or adjustment purposes and, for example, the cutting device and a gluing device or a pallet carousel for taking over the labels. The resulting labels are removed dog-wise by the operator before the machine is put into operation.

However, this poses a safety risk for the operator since he has to intervene in potentially rotating devices and is still time-consuming.

task

Based on the known prior art, the technical problem to be solved is therefore to specify a labeling device with which the setting up of a new label tape can be carried out more quickly and more safely for the operator. solution

This object is achieved according to the invention by the labeling device according to claim 1. Advantageous developments of the invention are covered in the subclaims.

The labeling device according to the invention for containers, such as bottles, comprises a cutting device for separating labels from a label strip, the cutting device comprising a cutting cylinder and a cutting element, wherein the label strip can be transported along the cutting cylinder for separating labels, and is characterized in that it is characterized that in the area of the cutting cylinder or downstream of the cutting cylinder a suction is arranged such that it can suck a label transported along the cutting cylinder or along a device arranged downstream of the cutting cylinder from the cutting cylinder or the device.

The cutting device can either be designed in such a way that the cutting element is integrated in the cutting cylinder or is arranged outside the cutting cylinder and, in cooperation with the cutting cylinder, effects a cutting of a label strip guided along the cutting cylinder into individual labels. The device arranged downstream of the cutting cylinder can be a transport device for the labels cut by the cutting device in the form of a rotatably mounted cylinder, so that the device does not carry out any further processing of the label and merely carries it out. Alternatively or additionally, the device arranged downstream of the cutting cylinder can also comprise one or more devices for further processing of the label.

The suction is always arranged downstream of the cutting element. It can be arranged so that it can suck off a label from the cutting cylinder before it reaches the transfer point from the cutting cylinder to the downstream device. It can therefore be arranged in particular in an area which extends between the cutting element and the transfer point of the label to the downstream device.

If it is arranged such that it can suction off a label transported along the device arranged downstream of the cutting cylinder, the suction device can preferably be arranged in a region which is upstream of a gluing device and / or upstream of a transfer point of the labels from the device to a device further downstream device, in particular located upstream of the transfer point of the labels to the container. Furthermore, the suction can be arranged in such a way that it can take over transported labels along the cutting cylinder, being arranged downstream of the point of transfer of the labels to the downstream device in the direction of rotation of the cutting cylinder. In this embodiment, a label to be vacuumed is then transported beyond the transfer point to the downstream device along the cutting cylinder and vacuumed.

By means of this labeling device, in particular the leading 5 to 20 labels falling when the label tape is changed can be reliably removed as rejects from the cutting device or a downstream device without the operator still having to reach between the rotating parts, in particular between the rotating cylinders .

It can be provided that the suction comprises a component which extends along a region of a circumferential surface of the cutting cylinder or the device.

That the component stretches along the circumferential surface of the cutting cylinder or the device is to be understood such that the suction is arranged outside the cutting cylinder or the device, that is to say it is at a distance from it, so that the label band and / or the labels at least can run through between the suction and the cutting cylinder and / or the device and can be sucked off by the suction. The suction can be done reliably.

In a further development of this embodiment it is provided that the area comprises an Winkelbe range of at least 10 ° along the peripheral surface of the cutting cylinder or the device.

In this development, a reliable suction of excess labels is ensured even with a rapid rotation of the cutting cylinder or the device, provided that this is configured as a cylinder.

The suction can be designed to bring about a negative pressure for suctioning off the label.

Since the labels have only a small mass, reliable suction can be achieved by creating a vacuum. Furthermore, the suction can be connected to a vacuum pump assigned to the cutting cylinder and / or the downstream device for loading the cutting cylinder and / or the downstream device with a vacuum in order to generate the negative pressure; and or

the suction can be designed to be connectable to an external vacuum pump in order to generate the oppression.

The vacuum or the negative pressure generated with the vacuum pump can thus be used in an energy-efficient manner for the suction of the labels, particularly when starting up the labeling device, in which only a little vacuum power is required. Due to the alternative design of the external vacuum pump, which can be designed, for example, as a known suction device, additional lines to the vacuum pump of the labeling device can be omitted and the complexity of the labeling device can be kept as low as possible.

In one embodiment, the suction comprises a component facing the cutting cylinder and / or the device, in which a suction opening for suctioning off the label is arranged, the component preferably being a component produced by means of a generative manufacturing process. In this embodiment, the component can, but need not, have been produced by means of a generative production process. For example, the component facing the cutting cylinder and / or the device can also have been produced by another method.

The suction opening prevents labels from being inadvertently left in the area of the labeling device and in particular in the area of the cutting device or the downstream device.

The suction device can comprise a collecting container for suctioned labels.

In this way, labels that are left unintentionally in the area of the labeling device can be avoided.

In one embodiment, the suction is detachably connected to the labeling device.

The suction can thus preferably only be attached during the commissioning of the labeling device or when setting the new label tape and can be removed during normal operation in order not to hinder the normal operation of the labeling device. Alternatively, you can it should also be provided that the suction (as a permanent installation) is attached during commissioning and during operation of the labeling device. It can then additionally serve as protection for operators from reaching into moving parts.

Furthermore, a fastening device can be provided for establishing the releasable connection between the suction and the labeling device. The fastening device can bring about the establishment of the releasable connection by establishing a positive connection and / or establishing a non-positive connection.

This further development ensures a reliable arrangement of the suction.

In a development of this embodiment, the fastening device comprises at least one of a clamping element, a click element, a plug element.

Preferably, the loosening or fastening of the releasable connection (especially when seeing the clamping elements, click elements or plug-in elements) requires the use of tools, such as a screwdriver or a wrench. If the suction serves as protection, unintentional or careless loosening of the connection can be prevented. Alternatively, a tool-free arrangement of the suction and removal of the suction (for example, by actuating the clamping elements, click elements or plug-in elements), which can only be carried out with the hands of the operator, can be possible.

The device can comprise a vacuum cylinder or a gripper cylinder. Instead of or in addition to the gripper cylinder, a pallet carousel can also be provided.

The use of the suction in combination with the devices downstream of the cutting device is particularly advantageous.

The labeling device can comprise a gluing device for applying glue to separated labels downstream of the cutting device, the suction device being arranged upstream of the gluing device and / or the suction device being arranged downstream of the gluing device and upstream of a transfer point of a label to a container and / or wherein the suction is arranged downstream of a transfer point of a label to a container.

An unreliable suction of labels already provided with glue or a sticking of the suction can be avoided with the first variant. The other variants require partly by sucking in labels with glue, which can result in increased maintenance. However, this can be used to advantage to remove incorrectly glued labels.

Provision can also be made for the labeling device to be designed to suppress the suction of the label in the suction by means of the Venturi effect and / or for the labeling device to be designed to suppress the label in the suction by means of the Coanda- Effect. The number of moving components can thus be reduced.

Detailed description

FIG. 1 shows a labeling device 100 according to an embodiment in a schematic view. The components of the labeling device shown here are not shown in relation to the rest of a possibly provided label machine for applying labels to containers, such as bottles, but only illustrate the devices relevant to the invention.

All implementations known in the prior art can be considered as a labeling device or more generally as a labeling machine. For example, the labeling device can additionally comprise a carousel 109 or a linear conveyor for transporting containers 191, it also being possible to provide suitable application devices for applying labels. However, the application can also be carried out by the downstream device 102, as shown here. These are also well known from the prior art. According to the invention, such labeling devices and / or labeling machines come into consideration which provide non-self-adhesive labels on a label tape and cut this to the container before application and optionally glue it.

In the transport direction of a label strip 130, the labeling device initially comprises at least one cutting device 101. This cutting device 101 comprises a cutting cylinder 1 1 1, along the circumferential surface of which the label tape 130 can be transported. In addition, the cutting device 101 comprises a cutting element 112 which, in cooperation with the cutting cylinder, can separate the label strip into individual labels.

In the embodiment shown here, the cutting element 1 12 is arranged outside the cutting cylinder 1 1 1 and can be formed, for example, as a movable cutting knife or as a plurality of movable cutting knives. The cutting cylinder 1 1 1 is then usually designed in such a way that it has one or more depressions along its circumferential surface, along which the label strip is guided, so that when the cutting cylinder is rotated and the cutting element is moved, the cutting element is moved into the depressions of the cutting cylinder, so that the label tape is cut at these points.

Alternatively, the cutting device 101 can also comprise only one cutting cylinder 1 1 1, in which one or more cutting elements are integrated, which can be moved outward in the radial direction of the cutting cylinder, for example, in order to move a label strip arranged on the peripheral surface of the cutting cylinder during this movement outward to sever.

A variety of embodiments are conceivable for the cutting device. For the invention, however, it is only essential that a cutting device is provided which comprises at least one cutting cylinder, along the circumferential surface of which the label strip is transported and can be divided into individual labels during this transport.

A further device 102, for example a transfer cylinder, gripper cylinder, vacuum cylinder or pallet carousel or the like, can be provided in the transport direction of the labels thus separated downstream of the cutting cylinder 11. The labels, which are now isolated, are transported along this and then, for example, fed to or passed past a gluing device 108 in order to apply glue to the cut labels and then to apply them to the containers. The device 102 itself is preferably designed so that it does not glue the cut labels. Any gluing device is therefore arranged downstream of the device 102 or at most along its direction of rotation downstream of a transfer point of cut labels from the cutting cylinder 11 to the downstream device 102.

According to the invention, the labeling device 100 comprises a suction device for suctioning labels transported along the cutting cylinder or along the device 102 Cutting cylinder or from the device. The suction is shown here with 104 and 105 and 107 cal. It should already be mentioned here that each suction 104, 105 and 107, independently of the other suction devices, can also be provided alone or several suction devices in combination.

This suction allows suction of cut labels, in particular when a new label tape is introduced into the labeling device, since this may require adjustment of the relative movement of the cutting device (in particular the cutting cylinder) and the downstream devices and other devices. This usually results in a number of labels that are unsuitable for labeling containers, for example because they have folds or are not properly cut. The suction is provided according to the invention to remove these labels from the cutting cylinder 1 1 1 or from a device 102. According to the invention, only one suction device 104 or 105 must be provided for this purpose, so that the suction devices 104 and 105 can also be provided individually and no two suction devices in 104 and 105 are necessary. If a suction is provided, it can, for example, be arranged at positions 104 or 105.

The suction 104 or 105 is in any case arranged in the transport direction of the cut labels downstream of the cutting element or generally the point at which the label band is cut into individual labels. If the cutting element is integrated in the cutting cylinder, this point is the rotary position of the cutting cylinder, in which the severing of the label is effected by moving or actuating the cutting element. This point usually corresponds to a predetermined angle setting of the cutting cylinder and is therefore well defined in the operation of the labeling device.

In the embodiment shown in FIG. 1, the suction 104 is arranged downstream of the cutting element in the direction of rotation of the cutting cylinder (which is also called an impression cylinder if a separate cutting element is provided), in such a way that it is transported along the cutting cylinder 1 1 1 Can suck off the label at least before the transfer point to the downstream device 102. The label is therefore removed from the cutting cylinder 1 1 1 by suction before the label is transferred to the downstream device 102. The suction 104 can be arranged in an angular range a between the cutting element and the transfer point of the label from the cutting cylinder 1 1 1 to the downstream device. The angular range a can extend over 10 ° or more. For example, it can also extend over 25 ° or more or over 35 ° or more. The suction 107 is arranged in the direction of rotation of the cutting cylinder downstream of the transfer point of the label from the cutting cylinder 1 1 1 to the downstream device 102. From the suction is thus arranged so that it can suck a label transported from the cutting cylinder beyond the transfer point of the label from the cutting cylinder 1 1 1 to the downstream device 102. This transport of the label beyond the transfer point through the cutting cylinder 1 1 1 usually does not occur (in the trouble-free labeling operation). However, it can occur, for example, when changing a label roll if the setting of the cutting cylinder 1 1 1 is adapted to the new label roll. The case can also occur if (intentionally or unintentionally) the label is not transferred from the cutting cylinder to the downstream device 102 during operation of the labeling machine. In such a case, for example, the vacuum holding the label on the cutting cylinder cannot be deactivated at the transfer point, so that the label is not transferred but is transported further along the cutting cylinder. This can occur intentionally (for example, if damage to the cut label is detected by an inspection device arranged in the region of the cutting cylinder) or unintentionally (for example, due to a malfunction of the vacuum elements of the cutting cylinder).

In any case, the suction 107 can then be used to extract a label from the cutting cylinder, which is transported along the cutting cylinder along the transfer point of the label to the downstream device 102. The suction in the angular range 02 between the transfer point of the label from the cutting cylinder to the downstream device and the transfer point of the label strip 130 to the cutting cylinder 1 1 1 is preferably arranged. This angular range 02 can for example be at least 10 ° up to 25 ° or up to 35 °. Values in between or larger values can also be selected.

The suction 105 is arranged such that it can suction a label transported along the downstream device 102. The suction is therefore preferably after the transfer point of the label from the cutting cylinder 1 1 1 to the downstream device 102, but in the direction of rotation of the downstream device or in the transport direction of the labels along the downstream device upstream of the gluing device 108 and / or upstream of the Transfer point of the labels to the container 191. The angular range 03, in which the suction 105 is arranged, can for example also extend over at least 10 °. It can also extend up to 15 ° or up to 25 ° or up to 35 ° or assume any values in between. As shown in FIG. 1, the suction 104 or 105 or 107 can be a component 141 or

151 or 171, which extends along at least a portion or a portion of the peripheral surface of the cutting cylinder 1 1 1 or the further device 102. A suction of a label, for example, into a collecting container 142 or

152 and 172 respectively. For this purpose, the component 141 or 151 or 171 can be connected to the collecting container 142 or 152 or 172 via a suction line 143 or 153 or 173.

The component can, as also indicated in FIG. 1, have a curved suction surface which faces the cutting cylinder 11 or the device 102. This curved suction surface can comprise at least one suction opening through which an aspirated label can be removed from the cutting cylinder or the device 102. The curvature of the suction surface can preferably correspond to the curvature of the peripheral surface of the cutting cylinder 1 1 1 or the device 102, the suction surface being arranged at a distance from the peripheral surface of the cutting cylinder 1 1 1 or the device 102. This distance can be selected so that a label tape or label can be moved between the suction surface and the cutting cylinder 11 or the device 102, but at the same time a reliable suction of the label can be effected through the suction surface.

The component 141, 151 or 171 is preferably a component produced by means of a generative manufacturing method such as 3D printing. Generative manufacturing processes are all non-machining manufacturing processes, in particular manufacturing processes in which the component is built up layer by layer from a (structureless) basic material. Such methods are generally known.

As indicated in FIG. 1, the component 141 or 151 or 171 of the suction device can extend in an angular range along the circumferential surface of the cutting cylinder 11 or the device 102. This angular range is determined by the angle which two jets emanate from the axis of rotation of the cutting cylinder or device 102, one jet being the first limiting surface of the suction device or at least component 141 or 151 or 171 in the transport direction of the labels and the other jet being happens in the transport direction of the labels second boundary surface of the suction or at least the component 141 or 151 or 171. The angular range can extend, for example, over a = 10 ° along the circumferential surface of the cutting cylinder or device 102. Larger or smaller angles are also conceivable. An angular range of a = 10-60 ° is preferred, although angles of 10-35 ° or 10-45 ° are also conceivable. In order to ensure the suction of the label from the cutting cylinder 1 1 1 or the device 102 with the aid of the suction 104, 105 or 107, it can be provided that at least the component 141 or 151 or 171 is subjected to a vacuum. Alternatively or in addition, the collecting container (142, 152, 172) or the suction line 143 or 153 or 173 can also be subjected to a vacuum. For this purpose, for example, the vacuum pump 106 shown here in dashed lines can be used, which in normal operation of the labeling device, for example, applies a vacuum cylinder as a further device 102 to a vacuum. By means of one or more additional lines that branch off from this vacuum pump, the respective suction can be acted upon with sufficient negative pressure in order to detach a label from the device 102 or the cutting cylinder 11.

Alternatively, the vacuum pump 106 can also be understood as an external vacuum pump which is provided and operated exclusively for the application of the suction 104, 105 or 107. It is then preferably not connected to other devices of the labeling device.

Alternatively, it can also be provided that the suppression when the label is sucked off is generated in the suction by means of the Venturi effect, for example in the suction line 143 or 153 or 173. For this purpose, the compressed air, which is generated by a stationary vacuum pump 106 (which, as just described, for example supplies a vacuum cylinder with vacuum), can be introduced into a line connected to the suction line 143, 153 or 173, as a result of which of the Venturi effect in the suction line itself a negative pressure is generated so that a label can be detached from the cutting cylinder 1 1 1 or the device 102. Alternatively or additionally, the Coanda effect can also be used to generate the negative pressure. Both the use of the Venturi effect and the Coanda effect do not require any other media, only a (compressed air) supply is necessary. Alternatively or additionally, a jet pump can also be used to generate the suppression. For this purpose, the exhaust air from the existing overall system is preferably used, such as the exhaust air from the vacuum cylinder, vacuum pump or the like (air recycling). Furthermore, it is also possible to use an additional medium, preferably a gaseous medium

Alternatively, this effect can also be realized on the component 141 or 151 or 171 or in the collecting container 142 or 152 or 172. It is also conceivable to provide both a vacuum in order to generate a vacuum for suctioning off the label (for example by applying the vacuum in the collecting container 142, 152 or 172), and at the same time, using the Venturi effect or one of the other effects described above, to generate a suppression in the suction line 173, 153 or 143 in order to assist the suctioning of the label.

In the embodiments shown so far and in particular in FIG. 1, the suction (104, 105, 107) were shown in each case arranged downstream of the cutting cylinder but upstream of the application device 108. This has the advantage that no glue residues can get into the suction.

However, it can also be provided that the suction (not shown here) is arranged downstream of the gluing device 108 (in the direction of movement of the labels). The suction can in particular be arranged downstream of the gluing device, for example on the periphery of the further device 102 (such as a vacuum cylinder or the like). For example, it can be arranged between the gluing device 108 or the point at which the glue is applied to the labels, and the point of transfer of the label to the container (which is transported in the cassette 109). Alternatively, it can also be provided that the suction is arranged, for example, along the periphery of the device 102 after the point of transfer of the label to the container. This is to be understood in such a way that, for example, when the cylinder 102 rotates clockwise, the suction in the direction of rotation of the cylinder is arranged after the point of transfer of the label to the container (s).

In some embodiments, one or more additional devices in the form of transport cylinders or the like can also be arranged downstream of the further device 102. One or more suction devices can also be provided accordingly in their areas.

Each of the suction systems described can be designed in accordance with each of the previously described and / or the subsequent embodiments.

Figure 2 shows an enlarged view of a suction 104 (instead of this, suction 105 or suction 107 may be provided) in the area of the cutting cylinder 1 1 1 in a cavalier's perspective.

As can be seen, the component 141, which at least partially faces the cutting cylinder 1 1 1, in this embodiment comprises at least one suction opening 271, which is connected to the suction line 143. A label that moves along the cutting cylinder can be sucked off through this suction opening, which can be subjected to negative pressure. This can the negative pressure applied to the suction opening, or in particular the negative pressure which acts on the label by means of the suction opening, is greater than a negative pressure applied to the label by the cutting cylinder. This ensures that the label experiences a force resulting in the direction of the suction opening and is thus sucked off by the cutting cylinder 1 1 1. Alternatively, it can also be provided that any suppression exerted by the cutting cylinder on the label is switched off or at least reduced as the label moves past the suction, for example by no longer having one or more vacuum openings in the cutting cylinder that hold the label be subjected to a vacuum. Alternatively, it can also be provided that an overpressure is applied to the label starting from the cutting cylinder in order to actively blow the label away from the cutting cylinder. Each of these embodiments reduces the force with which the label is held on the cutting cylinder, so that detachment of the label from the cutting cylinder can be achieved more easily with the suction 104 or 107. In this way, tensions in the label can also be reduced, which reduces the risk of unintentional tearing of the label and thus of label residues remaining on the cutting cylinder.

The vacuumed label can then be fed to the collecting container 142 via the suction.

FIG. 3 shows a further embodiment for the labeling device 100 in a cutout, in which only the cutting cylinder 11 and a suction device 104 associated with it are shown with the suction line 143 on, for example, a stand table 390 of the labeling device. It goes without saying that instead of the cutting cylinder 1 1 1 and the suction assigned to it, the other device 102 with the suction 105 assigned to it could also be used here.

In the embodiment shown here, the suction 104 is detachably connected to the labeling device 100. For this purpose, the component 141 is for example connected via a first connecting element 382 to a second connecting element 381 on the standing table 390. For this purpose, in particular a third connecting element 383 can be provided, which creates the detachable connection between the first connecting element 382 and the second connecting element 381. This third connecting element 383 can be designed, for example, as a clamping element or click element or plug element, so that it can preferably be loosened or fastened simply by manual operation of an operator without the use of tools, so that the releasable connection between the connecting elements 381 and 382 is manufactured. The connecting elements 381, 382 and 383 are provided together as a fastening device, since this can make the releasable connection between the suction and the labeling device.

Instead of tool-free fastening devices for establishing or releasing the releasable connection between the suction 104 and the labeling device, other fastening devices can also be used for which the use of tools is usually necessary. For example, the suction with the third connecting element 383 in the form of a screw or a flange can be connected to the labeling device 100. Tools such as screwdrivers are usually necessary to operate them. The use of connections that can only be detached or attached using a tool is particularly advantageous if the respective suction is also to take on a protective function, for example to prevent an operator from being able to intervene in rotating parts.

In the embodiment shown in Figure 3, the suction line 143 is provided separately from the fastening device 380. In one embodiment, it can alternatively also be provided that the fastening device 380 is part of the suction line 143 or that a releasable connection with the labeling device is established with the aid of the suction line via suitable connecting elements or fastening devices. This can be the case in particular if the vacuum pump provided in the labeling device is used to apply suction or vacuum to the suction 104. The detachable connection of the suction with the labeling device can then be established in that the suction line 143 is connected to a vacuum connection provided for this purpose of the vacuum pump of the labeling device. This can be done via a sealing ring or sealing flange, so that the suction can be subjected to vacuum and / or vacuum as reliably as possible, even if the suction is dismantled several times and releasably connected to the labeling device. Here too, the establishment and / or loosening of the detachable connection between the suction device and the labeling device can be carried out without tools or requiring tools (ie only with a tool such as a wrench or a screwdriver) or with the use of tools.

All of the embodiments described in FIGS. 1 to 3 only with reference to the suction 104 or another one of the suction devices can also be transferred to the suction devices 105 and 107. The same also applies to designs or implementations or examples which have only been described in connection with the suction 105 or the suction 107.
