Description

The The present invention relates to a labeling device.

labeling devices are well known. They usually include conventional pressure-sensitive ones Roll feeders, wherein the laminating coating forming the surface material, the adhesive, the removable one Silicone and the carrier material combined into a role. The printer then takes over his task by printing, punching and laying the label stock on a roll is kept. Established, technical procedures will follow Used to attach the laminated label to an article following transport and to raise. The carrier material will for the Label as a transport element, as a conveyor, away from the roll used up to the application position, and it is a common practice is, then the carrier material as waste, as there are no more in the facility Use has more.

In recently, Time is carrier material free, lightweight or thin designed, synthetic label materials have been developed Cost advantages with it, but a reduced tensile strength and can have a high expansion behavior. These properties cause additional Difficulties during of printing, punching and reel spooling during conversion. After punching and stripping the waste material is the lamination in their extensibility less stable, causing fluctuations in the Roller winding tension leads. The low thickness measurement of both the surface and the carrier material required during punching compliance with tight tolerances to a label overlap to prevent what the damage of the thin one support material or the funding would result or to avoid a label undercut that would lead to that Label partially gets stuck on the matrix.

One Another major problem is the increased risk of carrier web jumps, or the missed release of the label from the substrate during the Etikettenaufbringens, especially at a high feed rate than Consequence of the uneven punching.

A Label transfer device is known from WO 99 03737, in a sensor monitors the position of a label and an orientation causes when the label compared to a given Moved to default position. There are also label transfer devices in US-A-5,256,239 and EP-A-0852203.

The The present invention is directed to those described above To solve problems, by providing an improved labeling device in which the label material with improved precision and Efficiency is processed.

According to the present The invention provides a labeling device with a labeling device, a product labeling device, a product feeder and a control means serving to position and the speed of a product on the product feeder promoted will, and besides the position and speed of an associated label in a label application position using the product labeling device applied to said product is to be, the control device also serves to, the Speed and position of the product and its associated label to regulate speed and position differences between the label and the product on which it is applied based on the recorded positions and speeds, compensate for the label with the product surface in the Label application position due to a juxtaposition position (juxtaposition) of the product labeling device and the product in the label application position, and the speed of the label and the associated product to control so that the label and the associated product during the Label application at substantially the same speed exhibit.

The Accuracy of label positioning can be achieved with this disposition be substantially improved, as between a label and the associated product surface No relative displacement is left as soon as the label is applied to the product.

positive It should be noted that the speed of the label and the product surface while label application as linear or rotary speed (where the label or product is rotating around any axis) can take place, which is dependent on the respective desired labeling operation.

It is an advantage that during the label application the label and the product surface one have constant speed. With such Disposition can label the product in a uniform and be applied smoothly, thereby increasing the precision becomes, with which the label application can take place.

To that purpose be installed in the control device one or more sensors, the to serve the speed and / or position of the label and / or the product surface to capture. The sensors can take any suitable form and in any combination in electrical, magnetic, mechanical or optical devices etc. be included.

advantageously, There is at least one label sensor that can be an optical one can, and is so ready for the presence of a specific Area to capture, such as the leading edge of the label, the For example, it may already be inside the labeling device.

Prefers the controller serves to, before and / or during label application the speed and / or position of the label and / or the associated product surface to regulate.

The Control device is preferably in a label application device installed, which serves the label on the product surface advantageously with a uniform feed so to transport that applied the label at a constant speed can be.

Preferably the label applicator serves to do this before application of the label on the product, the positional orientation of the label in a label application position, and further preferably is a predetermined setting position.

The Label applicator can be any suitable shape and include a rotating or linear device. It can also be a direct contact device in which in the application position the label with the product surface due a juxtaposition position of the label applicator contacted with the product in the application position becomes. An embodiment in terms of a rotating label applicator is a pressure roller, which turns the label and is ready for the label using an overpressure to apply, which may be continuous or intermittent, such as a pulse pressure, which may be from the controller is controlled.

at a preferred embodiment promoted the label application mechanism labels the label at a speed which corresponds to the speed of the corresponding product surface. In a particularly preferred embodiment, the label application device serves to Prior to label application, the position of the label in relation to align with the speed of the product surface, so that in the label application position the label and the product surface with approach each other at the same speed.

On this way you can all Differences between product surface position and label position over one Regulation adjustment of the label applicator compensated become.

Prefers the labeling device further comprises a label feeder which Feed labels into the label applicator. preferred includes the label feeder a reusable conveyor for supporting the label underlay using an electrostatic attraction, the between the conveyor and the label is generated.

The Electrostatic attraction can be generated in any suitable manner be such as by feeding a high voltage on at least one section of the conveyor, or through the use of an electrostatic induction element attached to a Section of the conveyor is arranged adjacent to so an electrostatic charge to be able to produce.

A electrostatic support is particularly suitable where the label stock is laminated Structure having an adhesion layer includes (for example liability for a product). This surface layer becomes, for example still treated with silicone or coated to apply for the label material to allow a roller bearing.

The Label material may be, for example, a laminating structure which a surface material layer having a first side herein as the surface side is designated, which can be printed, and with an opposite Side which is treated with an adhesive (i.e., coated) becomes.

With Such a label material construction, the label material on the subsidy be carried by means of an electrostatic attraction, between a surface side of the Label material and the conveyor is produced. In this way, the label material can be released supports be without putting on the carrier web an excessive Pressure exerted must become. Furthermore is the adhesive side to the outside whose advantage is clear from the description below evident.

at another embodiment For example, the label material may include a substrate which the surface material before / during the Put on / s on the conveyor wearing.

The support material Can be a lightweight carrier web be, for example, to carry the label material - in front of you Print / cut labels - for convenient storage the label material is used in a reel spool form.

at a particularly preferred embodiment supports the conveyor the label material during cutting a label from the label backing, and For this purpose, the label cutting devices are on the conveyor in an opposite Placed side by side.

Of the Label cutter can take any suitable form, but includes this advantageously a laser device for cutting the supporting one Label documents.

The Laser device may have any suitable shape, but preferred make it a precise one Laser beam with a low energy output ready, which the Can cut off label backing without doing the conveyor receives an incision.

These Embodiment and in particular the combination with an electrostatic supported label material, which the laser cuts through, allows a precise, linear label cutting, completes the process of punching with the printing / conversion processes off and lets the label separation immediately before label application to.

A Laser control can be installed in the device which the beam intensity of the laser controls.

The Laser application allows an efficient and precise Cutting off the label material and allows particularly advantageous Cutting the label pads with the outward facing Adhesive layer side, since the laser cutting edge is not affected by the adhesive becomes (as with a conventional Cutting blade is the case).

Of the Label cutting process creates around the label / labels around and in terms of label stock usually one Matrix waste.

consequently can any surplus material that caused by the label cutting process, d. H. the matrix waste be eliminated by the label / the labels remain on the conveyor. The matrix waste - possibly in label form - can wound on reel spools for disposal from the device become.

In Devices using a continuous feed for the label material, every interruption in the label material is reconnected, by using established techniques for one splice, a so-called "splicing." The assemblages become herein as splices designated.

at a further embodiment according to the present Invention become splice sites, the while earlier operations accomplished such as coating, printing, converting or any role-linking process detected by conventional splicing applied to those skilled in the field in general are known. Therefore, they will not be described in further detail herein described. The occurrence of splice sites is then in the Laser control input, which - while passing the Splice - the cutting process prevents and thus allows that it is wound up as part of the matrix waste.

Of the Label cutting operation can be performed so that predetermined, d. H. continuously uniform spacing between each label exists are, but also without distances accomplished be used to label labels known as die-cut manufacture. This can be controlled by the laser control.

The Conveyor may have any suitable shape; but it is preferably one Endless conveyor belt.

The Conveyor can be made of any material, but advantageously is the funding constructed from a material that is electrostatically chargeable, d. H. of metal or of a metallic material, such as Steel, stainless steel.

These Attachment may be a label transfer device for executing the Release the label from the conveyor include.

The label transfer device may have any suitable shape, but preferably it is a roller or drum which is generally cylindrical and around which the conveyor passes to effect release of the label from the conveyor. It is advantageous if the roller has a sufficiently small diameter to clear the label from the conveyor belt to be able to support / effect.

Preferably is the conveyor flexibly flexible and at its end a conveyor made of metal or from a metallic material.

The flexibility the conveyor allows, that they are leading around something can, such as a label transfer device, the one Roller with small diameter for includes the label release / transfer, as above has been described.

to support the release from the conveyor can be electrostatic holding a cut off label in the conveyor shortened or at the release point except Force, whereby the separation of the label from the Conveyor is driven forward.

This is important because the expected useful life of the conveyor significantly increased by maximizing the roll diameter can be around which she leads the diameter being due to the flexibility of the label with respect to the conveyor is determined. As for the latter parameter, the Application of electrostatic attraction to supporting Carrying the label on the conveyor advantageous over using the adhesive side of the label as this is usually the removal of the label would require, for a tine-shaped or a peeling off metal piece is used, which the conveyor / label material would impose a heavy burden.

The Laser control can be so functional that the cutting process in response to the changes adapted in the conveyor speed becomes. For this purpose, the laser control is advantageously in contact with a detector, which determines the speed of the conveyor detected.

The Control device also serves in addition, the speed of the conveyor to control. The laser control can be independent of this, or in conjunction with this, or over a control by this controller will work.

Consequently can speed up the product labeling supplied Labels at the speed of the labels in the product labeling device be synchronized.

The Product labeling means may comprise the product delivery device which may include a linear device, i. H. a sponsor or a rotary device, such as a printing cylinder or a printing drum, or a revolving automatic turret.

Preferably serves the product feeder to the product (and in particular advantageously with a Registration) into a predetermined label application position bring to.

The Product may be stored stationary with respect to the product delivery device or alternatively, the product may be in relation to the Move device. For example, a product of one Wrapped label, the product in relation to the product feeder is rotated to allow the wrapping of the label.

advantageously, is a label feeder, such as the labeling device described above, with the product feeder electronically coupled, such as with the corresponding Electronic transmission of feed rollers and / or with a servomotor control or with other drives / an actuator, so that the labels and products at a substantially same speed be supplied can. Furthermore, the labeling device with the label application device be coupled, leaving a label as soon as it reaches the label applicator promoted essentially be aligned with the product spacing can.

In In this application, the term Product Distance is used to denote the Space between the product surfaces to be labeled in sequence to name. Consequently, when a product is rotated, for example during the Label application for a label wrap, the spacing of the labels in the Label applicator with the related Feed rate of the rotating product around its own Axis and adapted to the feed rate of the conveyor.

It is not important that the label and the product distance are exactly the same, since the control unit according to the invention differences in the intervals can compensate by changing the relative position / speed of the label in relation to the product, or vice versa, d. H. by repositioning the label before applying the label, supported in the label applicator, so that the label in the label application position in a Positional accuracy can be brought with the product.

The Labeling can also a Measuring equipment (such as a visual inspection system), which serves to measure the arrangement of the labels as soon as these are placed on the product.

These Measuring device is also ready so that they the position of the next / succeeding or of automatically align any other, predefined label, to apply it.

With this design of the system can prevent cumulative errors and individual position compensations are kept low, possibly while labeling even very high speeds can be achieved.

The The present invention will now be described by way of example only and with reference to the associated Drawings are described which show:

1 Fig. 10 is a diagram of an embodiment of the labeling device according to the present invention attached to a product labeling device.

2 FIG. 4 is a diagram of one embodiment of the product labeling apparatus of FIG 1 ,

3 is a schematic representation of the control device in the product labeling of 1 ,

4 is a schematic representation of an alternative embodiment according to the present invention.

Regarding 1 Figure 4 is a graphic view of one embodiment of the labeling device 200 illustrated in accordance with the present invention, the preferred product labeling 10 affiliated.

The labeling device 200 includes a label unwinding unit 202 , a laser unit 204 controlled by a laser controller (not shown), a label waste receiving unit 206 , a conveyor, which is a flexible, thin conveyor belt 208 made of metal and having the shape of a loop, wherein the conveyor belt 208 around a servo motor driven roller 210 rotates, as well as a label transfer intermediate roll 212 that has a smaller radius than the roller 210 having.

The product labeling device is in the 2 and 3 more clearly shown and its details are described below.

The label material has a laminating structure and comprises a surface material layer and an adhesion layer; it is stored in a reel spool mold and by motorized unwinding from the label unwinding unit 202 , passing over a pull roller 201 and on the conveyor belt 208 , to the labeling device 200 introduced.

The conveyor belt is powered by a charger 220 electrostatically charged, which induces an electrostatic charge in the conveyor belt. The labelstock is then supported by the static attraction force between the label surface material and the conveyor belt 208 has been generated, wherein the adhesion side of the conveyor belt 208 directed to the outside.

The label material is conveyed on the conveyor belt via a cutting station 213 transported past where the laser unit 204 to the conveyor belt 208 is placed in an operative abutment position.

As the labelstock passes this position, a low energy but precise laser beam is applied to the label stock to cut the labels as desired, either without spacing or with spaces between subsequent labels. The label waste material is from the label waste receiving unit 206 which rotates through a controlled servomotor at a finely tuned speed, with the tension roller 203 applies a tension control which is at the speed of the roller operated by the servomotor 210 and with that of the label unwinding unit 202 is synchronous. Splices that have been made during earlier operations, such as coating, printing, transferring / splicing operations, are detected by a conventional splice detector (not shown) and transmitted to the laser controller, which inhibits the cutting action as the splice passes the cutting station and thus ensures that it is reeled as part of the matrix waste.

After cutting the labels 24 which have been detached from the matrix base, they remain on the conveyor belt 208 subject to being electrostatically supported with continuous gaps between each label, or with no spacing, the laser should be set so that die cut labels are produced without a bridge (ie, there are no gaps between the labels). This endless flow of the conveyor belt and the label then moves (by the rotation of the servomotor-controlled roller 210 ) to Label transfer intermediate roll 212 for a transfer of the labels 24 to the product labeling device.

The speed of the conveyor belt 208 is from the controller 100 (in the 3 is shown) in the product labeling device 10 which is part of the label-product application process.

All changes in the conveyor belt speed are detected by the laser cutting unit, which controls the cutting process Automatically adjusts accordingly.

When the conveyor belt around the label transfer intermediate roll 212 passes, the smaller radius allows the label release of the conveyor belt 208 , where at this point the label on the drum 17 the product labeling device (description below) is placed.

The flexible nature of the conveyor makes it possible for this to be around the smaller radius roller 212 can lead so that the conveyor belt releases the label, which then itself on the drum 17 touches down. To support this operating process is the electrostatic charge, which is the label on the conveyor belt 208 stops, reduces, or aborts at the releasing transfer point, and thus the separation of the label from the conveyor belt 208 allows. This is important in that the expected useful life of the conveyor belt is determined by the maximized diameter of the releasing intermediate roll 212 The diameter of the roll around which it passes is greatly increased, with the roll diameter due to the desired flexibility of the label and its need on the conveyor belt 208 to remain to be determined.

With particular reference now to the 2 and 3 sets the product labeling device 10 the above-described labeling device as an endless label feeder (the labeling device 200 is shown in these two figures only in general). The product labeling device 10 includes a product delivery device 14 , a label application mechanism 16 and a controller 100 (in 2 shown) having a main controller (not shown) associated with optical label sensors 18 and 20 as well as with an optical product sensor 22 communicates. The optical sensors 18 . 20 and 22 react color sensitively.

The Main controller includes data storage options for saving of data captured by the sensors and other devices have been.

The label application mechanism 16 has a rubber coated, rotating vacuum drum 17 on, which has arranged on the outer surface openings. The openings are in fluid communication with a pneumatic system which serves to provide a vacuum (ie, suction) for transporting the labels to these openings, as well as overpressure for release of the labels from these openings. (The air pressure can from the central control device 100 to be controlled).

The product feeder 14 includes a linear conveyor belt 15 with which the products 34 continuously and sequentially in the label application position 32 to get promoted.

The label feed roller 210 , the vacuum drum 17 and the product conveyor 15 are each driven by a correspondingly controlled servo motor M, which are all connected to the main controller and to other control devices for communication between signals resulting therebetween. Each of these components 210 . 15 . 17 has an associated servo axis and a reference sensor that is also in communication with the main controller. In view of this embodiment, the conveyor belt is fully integrated into the servo control, which allows intelligently performing error correction maneuvers, as will become apparent from the following description.

however can the funding alternatively, from an externally controlled system, a reference coding circuit have to make it a subordinate operation of the conveyor belt to allow.

The optical label sensors include a label pitch sensor 18 that is to the conveyor belt 208 is located adjacent and serves to determine the label edge distance (ie the distance from the labels supplied to the product application system) and a label position sensor 29 that to the vacuum drum 17 is arranged adjacent and ready for the position of the subsequent labels 24 on the drum 17 capture. Also, the drum sensor is ready to detect the distance from the labels on the drum and the positional errors of the labels that are in the label application position 32 this serves to eliminate all subsequent inefficiencies during the transfer of labels from the transfer mechanism 212 towards the drum 17 capture. Follow-up errors in label transfer may occur due to the servo-controlled adjustment of the label head motor speed of the roller 210 or speed of the drum 17 be compensated.

The optical product sensor 22 is to the conveyor belt 15 arranged adjacent and serves to determine the product distance, ie the gap between the product surfaces to be labeled, which in this case is equal to the gap between the successive products. (The positioning setting of the product sensor is a user-adjustable parameter).

Everyone Sensor generates signals in response to a color detection with respect to leading edge the consecutive labels or the successive products, depending on.

The drum 17 also with the conveyor belt 15 controlled electronically so that the peripheral speed of the drum is matched with the speed of the conveyor belt for normal operation. With this arrangement approach the label 24 and the product surface to be labeled 36 with the same speed towards each other.

The label feed roller 210 and the drum 17 are also controlled electronically so that once the label is transferred to the drum, the label spacing on the drum (ie the space between the consecutive labels on the drum) is approximately equal to the product spacing. label supply 210 , The speed ratio of the drum 17 It is constantly recalculated based on the saved average label and product distance values (ie "stack") to ensure that the labels are fed at the correct distance, however, it is not absolutely necessary that the spacing of the labels on the drum and the distance of the products on the conveyor belt is exactly the same, as the present invention can compensate for differences in product and label spacings, as described below The system also allows manual correction of label and product spacing.

The control device 100 responds to signals from the label sensor 18 and from the product sensor 22 , The labels are from the label feeder 200 over the intermediate roller 212 where they are from the conveyor belt 208 be separated, to the drum 17 transported and on the drum 17 mounted (with the adhesive surfaces facing outwards), which holds each label in position over the drum openings. The position of each subsequent label on the drum 17 is supported (the label pitch) is from the label position sensor 20 Identifies which leading edge of each label 24 recognizes. In response, the axis position of the drum is detected and stored. These data set the position of the label 24 on the drum 17 firmly.

The drum 17 modifies the spacing of the labels with respect to a distance that is substantially the same as the product spacing.

Once the leading edge of a product from the product sensor 22 has been identified, the axis position of the drum and the axis position of the conveyor belt is detected and stored, whereby the relative positions with respect to the product and the drum are fixed. The controller then searches for the stored label position values (label stacks) to locate the "target label," ie, the label closest to the application position, where the distance value between the product sensor 22 and the label application position 32 is used. If it is found to be a product from the application position 32 is removed with a similar distance value (ie, within predetermined limits), the distance difference is calculated and (if it is within the predetermined limits) applied as a correction thrust for the drum axis position. Due to the servo control with their responsible motor M, the drum 17 Effectively accelerates or slows down to a position that precedes (or precedes) the application position 32 so as to be in the application position 32 to prevent any possibility of label acceleration. This compensation step overlays the existing electronic drive step. The correction step superimposes the feed speed of the label feed roller 210 during the servo control of the label feed motor.

Sequence fouling between the label feed rate (the speed of the roll 210 ) and the drum speed are also compensated by the correction step.

Once the positions of both the product and the label (on the drum 17 ), the label application position is calculated (provided that no correction is needed). Each occurring error is applied to a correction step in the drum feed speed.

In the label application position 32 becomes the vacuum-assisted label 24 turning the label length lengthwise and starting at the leading edge so as to drive the label gradually and in a continuously uniform manner in the direction of and into precise alignment with the product, the speed of the product being controlled Labels (by the rotating speed of the drum 17 is dominated) with the Geschwin the product is the same (within the device tolerances). This operation is automatically repeated for each label and its associated product.

alternative this may be on the total length of the Labels the air pressure immediately reversed in one place or by means of a control by the controller with pulses be offset.

The control of the label cutter can also via a corresponding connection of the laser control (not shown) with the control device 100 in the product labeling device 100 be integrated.

With This configuration will increase the speed of each label modified so that the label speed during the entire label application period at the speed of the corresponds to the product to be assigned.

It should be noted that the present invention is not limited to the use of a vacuum drum 17 is restricted. Other devices may be used which support labels on the drum, ie the drum 17 could be electrostatically charged to create a static attraction between the labels 24 and the drum 17 manufacture.

An alternative system will be in 4 shown and described below.

The System is the same as described above except that this alternative system the position of each product on the Conveyor belt recorded and a first-in-first-out (FIFO) stack.

The position of each product is used to generate a target position for label application. Both the labeling device 200 as well as the label applicator use the product conveyor as its central guide axis so that the amount of product feed rate required for the label to be transferred to be carried from the label carrier web to the label applicator in the application position can be calculated. This allows, for each product, the calculation of a conveyor belt position at which the associated label feed must start. This calculation also takes into account the carriage of the label from its starting position to the application position.

The labeling device 200 acts as a label delivery system which supplies labels to the label applicator (drum 17 ) as soon as the calculated conveyor belt positions are reached for each delivery. During normal operation, with consistently spaced products and labels and correctly entered data, both the labeler and the label maker should be used 200 as well as the drum 17 run smoothly, at a continuous feed rate, as controlled from the main axis of the product conveyor.

The Position of each label in the transfer mechanism can after the complete Separation from the label web will be scanned as soon as it is approaches the application position. All final position errors can in comparison to the assigned product position by means of a controlled Speed adjustment of the transfer mechanism can be corrected. After troubleshooting, the speed of the transfer mechanism returns the product speed back, before the label reaches the application position.

The speed of the label carrier web can be regulated to allow the transfer mechanism to use the label in the desired conveyor belt position to be allocated if the product spacing is not uniform. In extreme cases, it may be necessary for the labeling device 200 completely stopped.

The labeling device 200 sets the labels on the drum with individual loading mechanisms, as dictated by the data in the product stack. The target position for the label on the drum is calculated from the associated product position on the conveyor and from the intended conveying speed of the label from the grommet - on the drum - to the application position. The calculation of the label conveyance takes into account the feed rate during the control of the label carrier web, the feed rate during the control by the drum and possibly the effects of an acceleration.

task of the system is, with a uniform and continuous Feed rate in all units on the labels to apply the products. Any deviation leads to irregularities for the orientation data to be scanned, for errors in the processing parameters or sequential abuses during label transfer.

The data of the label spacing is recorded during the initializing advancement step of the label carrier web. If the data is consistent, an average tag gap value is assumed and used as the basis for subsequent calculations. Of the average label spacing value can be updated at any time during the operation process.

The information about the product distance can be sampled or entered by the plant operator. The average product distance information is less important than the product position so that "appropriate adjustments" can be made, especially if the product spacing is recognized as irregular 200 as soon as the product distance is the same.

Dependent on Prior actions may be the label carrier web at the beginning of the power supply be feeding or electrostatic.

If It is electrostatic, the power supply is only the rest Part at a conveyor belt position started, which for the desired Application position for feeding of the label on the conveyor belt is calculated. The calculation assumes that the drum continuously with the conveyor belt speed mitläuft, being the position on the conveyor belt can be equated with the position on the drum.

If already the feed is to be made, the calculated application position of the label on the conveyor belt (provided that no correction has to be made) with the product item to be assigned compared. The calculation then assumes that the drum continuously with the conveyor belt speed mitläuft, being a position on the conveyor belt can be equated with a position on the drum. The Extent of each resulting error is compared to a threshold.

If the error is less than the limit, the label feed will be attached to the previous feed, with the required Correction by a controlled speed adjustment of the label carrier web accomplished before the current label is completely removed.

If the error is greater than the limit is, the previous feed is controlled Slowdown for the rest stopped. The current feeder to be fed in will be displayed with a controlled acceleration at a calculated conveyor belt position started.

This allows for the labeling device 200 Automatically switches back and forth as required between continuous and intermittent operation, and compensates for missing products or deviations within the product gap.

Of course it is It can be assumed that the present invention is not based on the detailed information of the embodiment described above may, which has been explained only with reference to an embodiment.
