FIELD

[002] The present disclosure relates to methods and devices for removing labels. BACKGROUND

[003] Many products carry some form of label. The labels will typically designate the source and type of the goods, and in many instances have multiple labels providing other information that is relevant to the consumer about the product. Labels are typically attached to the product through the use of an adhesive.

[004] There are a variety of circumstances where one or more labels on a product need to be removed. For example, in some circumstances it is necessary to remove a label as the label carries information that is incorrect or needs to be updated.

[005] If the product carries multiple labels, this also raises the difficulty of how to selectively remove a desired label while retaining the other labels. In many circumstances it is not possible to remove one label without damaging the other labels, and as a consequence all the labels need to be removed.

[006] In other circumstances, the product is contained in a container and the product is subsequently used up. In this case, it is often cost effective to recycle the container. Typically, all the labels on the container need to be removed and then the container is relabelled afresh for subsequent use. [007] The removal of labels is a time consuming and difficult process. This is not only because it is difficult to remove the label, but in many cases even after a label is removed, parts of the adhesive still remain. The remaining adhesive may therefore also need to be removed, as its presence may comprise the quality of any new labels that are put onto a product.

[008] As such de-labelling is not only time consuming and expensive, but it will often place a constraint on the volumes and/or efficiency of products that are to be relabelled.

[009] There are currently varied methods for removing labels, including one or more of soaking and hand scrapping, mechanical turning and scrapping of the label with a blade, soaking then mechanically brush/scrubbing the label, and utilising chemicals to remove the label. All of these processes are slow and/or cumbersome and in some circumstances they may also damage the container. In addition, these processes are difficult to automate.

[0010] Accordingly, there is a need for improved means to de-label products. SUMMARY

EXAMPLE 1 - Removal of labels from a wine bottle using a single station

[00235] Studies that have been undertaken have demonstrated that the delivery of dry-ice particulates under pressure efficiently removes labels and associated adhesive from a bottle, and removes the need for soaking of the label and the use of solvents. The parameters used to de-label a bottle and remove associated adhesive are shown in Table 1.

Table 1- Parameters used to de-label a bottle

[00236] Figure 1 shows a schematic representation of one embodiment of a de-labelling device or apparatus and the process for de-labelling a wine bottle using the device or apparatus based on the studies undertaken. [00237] Referring to Figure 1, there is shown a schematic representation of a de- labelling device or apparatus 110 and the process for de-labelling a wine bottle using the device or apparatus 110, according to one embodiment. In this embodiment, a single station with 6 bottles is employed. The bottles are lined up at the same time, indexed, clamped, and for each bottle 3 jets/nozzles are used which can be turned on or off, as per the de-labelling requirements, described in further detail below.

[00238] In the embodiment shown, a wine bottle 112 is shown having multiple labels (114, 116 and 118) adhered to the surface of the bottle, which are to be removed by the de-labelling process by directing at the label a gaseous mixture of particulate dry ice under pressure.

[00239] In the embodiment shown, labels are to be removed from a wine bottle. Other types of objects suitable for de-labelling include for example other types of bottles, jars, cans and other containers. The process for de-labelling described herein is suitable for the removal of labels from objects made from a variety of materials, such as glass, metal (or metal allow), plastic or combinations thereof. For wine bottles, a typical size of a

2 2

label is 7 x 10 cm (70 cm ), although labels as large as over 200 cm (eg 17 x 12 cm) may need to be removed.

[00240] In the embodiment shown, the wine bottle 112 comprises a front label 1 14, a rear label 116 and a neck label 118. In the embodiment shown, the front label 114, the rear label 116 and the neck label 118 are all to be removed, however, it will be appreciated that the process may be adjusted to remove labels selectively. The process may be adjusted to remove one or more labels, in any desired combination and/or order. For example, there may be a desire to remove only the rear label 116 on the bottle, and still retain the front label 114 and the neck label 118.

[00241] The labels 114, 116 and 118 are typically paper-based labels (paper labels), that may or may not be further laminated, for example with a plastic covering, or be metallized paper labels. However, the process as described herein is also suitable for the removal of non-paper labels, for example synthetic labels made from plastic or labels made from metal foils. Labels composed of combinations of any of the aforementioned labels may also be removed. [00242] A variety of adhesives may be used to adhere labels to the surface of objects. Typical adhesives or glues used for labelling include water-based adhesives, solvent- based adhesive or hot-melt adhesives. Water based glues are typically either synthetic (eg composed of PVA polymers, acrylic polymers) or natural polymers such as casein, starch or dextrin base. Solvent based glues are typically composed of combinations of synthetic polymers and/or resins. Hot melt glues are typically solid thermoplastic materials which are subjected to heat until they melt and then applied to the label for adhesion.

[00243] In the setting where a large number of wine bottles are to be de-labelled, typically the process begins with the unpacking of the bottles to be de-labelled from a container/carton, and the bottles placed onto an in-feeder conveyer system (not shown). The bottles are then conveyed to the de-labelling part of the device 110, indexed and clamped. For example, six bottles may be automatically received into position, clamped and indexed in the de-labelling machine.

[00244] In the embodiment shown, each bottle is indexed and held on a base plate 120. Rotation of the base plate is achieved using a rotating spindle 122 driven by a controllable drive motor 124. The bottle 112 is clamped by way of a top clamp 126, the height of which may be adjusted using a hydraulic height adjustor 128, driven by a hydraulic unit 130. As such, the bottle 112 may be held in place and rotated for removal of one or more labels.

[00245] The device 110 comprises jets or nozzles 132, 134 and 136 for directing the dry-ice particulates at a label. In the embodiments shown, the jets or nozzles 132, 134 and 136 are controllable, and may be turned off or on, in any desired combinations of the one or more of the jets/nozzles 132, 134 and 136. For example, for removal of all the labels (114, 116 and 118), jets 1 (132), 2 (134) and 3(126) may all be activated. For the removal of the neck label 118, only jet 1 (132) may be activated. For the removal of only the front label 114 and the rear label 116, jets 2 (134) and 3 (136) may only be activated. For the removal of only front label 114, jets 2 (134) and 3 (136) may be activated, and the rotation of the bottle controlled so that only the front of the bottle 112 is exposed to the jets. For the removal of only rear label 116, jet 3 (136) may be activated, and the rotation of the bottle controlled so that only the rear of the bottle 112 is exposed to the jet. Control of the removal of specific labels, and combinations of labels, may for example be controlled through the use of sensors and/or cameras (not shown) which are known.

[00246] For example, for removal of just the front label or the rear label, the bottle may be rotated into a specific position and held in that position while the appropriate jet or nozzle is activated to remove the desired label. If desired, the object could also be rotated from side to side (eg within the limits for removing the label). For removal of both the front and rear labels, a stepwise removal of the labels could be undertaken, or alternatively, the bottle may, for example, be continuously rotated through a stream of the gaseous mixture of dry-ice particulates to remove both the labels.

[00247] In the embodiment shown, a mixture 138 of dry ice pellets 140 (provided from a source of particulate dry-ice) and compressed air 142 (provided from a source of the gas under pressure) is delivered via a pipe 144. Typically, a pressure of 200 psi of compressed and a dry ice pellet size having a diameter of 3 mm, in conjunction with a flow rate of the dry ice of 30 kg per hour, is suitable for removal of a labels from a wine bottle 112 by directing the gaseous mixture at the label under pressure at a distance of 100 to 130 mm from the bottle, although the jets or nozzle may be closer or further away than this distance. It will be appreciated that other sources of gas under pressure may be used, for example nitrogen or carbon dioxide.

[00248] Once a bottle 112 has been positioned in place, for the removal of labels 114, 116 and 118 for example, jets 132, 134 and 136 are activated by controlled opening of valves 146, 148 and 150. Opening of the valves 146, 148 and 150 permits the mixture to flow through jets 1, 2 and 3 (132, 134 and 136 respectively) and the stream of gaseous mixture under pressure 152 to be directed at a label on the bottle 112. Typically, a jet or nozzle has a slot opening of approximately 1 mm - 5 mm wide and a length of the slot of approximately 40 mm - 50 mm long.

[00249] At the same time, the bottle 112 is rotated by means of rotation of the base plate 120. As described before, and dependent upon the number and positioning of the labels to be removed, the bottle may be rotated into a desired position and held in that position, or alternatively, the bottle rotated continuously through the stream to remove the labels.

[00250] The mixture 152 (of dry ice pellets and compressed air) is ejected from the jets and the stream directed towards the bottle 112.

[00251] Without being bound by theory, the mixture 152 has a variety of properties that assist in removal of a label and adhesive, including the abrasive action of the pellets 140, the flow of the compressed air 142 and the cooling of the label, adhesive and surface of the bottle 112 associated with the temperature of the mixture.

[00252] The action of the mixture 152 under pressure, in conjunction with the specific or continuous rotation of the bottle to bring the labels 114, 116 and 118 into contact with the mixture 152, results in removal of each of the labels 114, 116 and 118 and adhesive associated with the adhered labels.

[00253] For removal of only the neck label 118, sensors and/or cameras are used to sensors to only activate jet 1 (132) by opening valve 146.

[00254] For removal of only the rear label 116, sensors and/or camera are used to only activate jet 3 (136) at that point in the rotation cycle where the rear label 116 comes into a position where is can be acted upon by the mixture 152.

[00255] For removal of only the front label 114, sensors and/or camera are used to only activate jets 2 and 3 (134 and 136) at that point in the rotation cycle where the front label 114 comes into a position where is can be acted upon by the mixture 152.

[00256] Combinations of the above sequences of events can therefore be used to selectively remove any combination of one or more of the labels 114, 116 and 118 during a cycle. Alternatively, all the labels can be removed at once during a cycle.

[00257] Typically, a cycle time of 12 to 20 seconds is used per bottle for de-labelling purposes. For example, the device 110 results in a cycle time for removing a single label from a bottle of around 13 seconds using a single nozzle or jet, although faster or slower cycle times can be achieved.

[00258] Once the cycle has been completed, the bottle 112 is automatically unloaded from the de-labelling device 110 and automatically conveyed to a buffer/drying station (not shown), utilizing blown air and buffing wheels. Once the bottle 112 is dried and buffed, the bottle 112 de-labelled by the process may then be automatically conveyed into a labelling machine without any further intervening treatment, where one or more new labels are applied, in accordance with the labelling requirements. Labelled bottles are them conveyed automatically via a conveyer system to a packing area and the newly labelled bottles repacked into cartons.

[00259] It should be noted that the process and device described result in the removal of the label without the need for pre-treatment of the label by soaking in water or by treatment with another type of solvent, nor does the process need treatment of the object to water prior to and/or after removal of the label. As such, the entire process does not require pre-treatment or post-treatment of a label with water or other solvent. In addition, it is not necessary, for example, to provide a water mist prior to, and/or in conjunction, with the gaseous mixture of dry-ice particulates (mixed or separately), in order to assist with softening of the label(s).

[00260] Further, aside from the efficient and convenient removal of the label from the bottle 112, the method and de-labelling device described also results in substantial removal of the adhesive/glue, thereby removing the need post treat the bottle after, including removing the need to post-treat the bottle with any additional soaking or other treatment with other solvent. In addition, dependent upon the nature of the object having a label to removed, the process and devices describe herein should not substantially damage the object (such as causing pitting and/or fissuring).

[00261] In another embodiment, the mixture 152 can be replaced with dry-ice snow. In this embodiment, dry-ice snow can be formed from liquid dry-ice provided under pressure and delivered via pipe 144 to jets 132, 134, 136, where dry-ice snow is formed upon exiting the jets or nozzle and then directed under pressure at the bottle 112. Typically, dry ice snow has a particulate size ranging from 1-500 microns. [00262] In another embodiment, the device 110 may also have multiple stations, each station being used for the removal of label(s) from a bottle. This provides an increase in the number of bottles able to be processed per unit time. For example, the device may have 6 stations machine catering for six bottles with each station having 3 nozzles. At a cycle time of 5 -6 seconds per bottle, this results in the de-labelling of 6 bottles every 6 seconds.

EXAMPLE 2 - Removal of labels from a wine bottle using multiple stations

[00263] Referring to Figures 2 to 4, there is shown schematic representations of a de- labelling process and a device or apparatus according to another embodiment in which the device or apparatus uses three separate de-labelling stations, each station devoted to de-labelling a specific label.

[00264] Referring first to Figure 2, there is shown a first station in the device 210 in which the front label 214 is to be removed from a wine bottle 212. In the embodiment shown, the wine bottle 212 has multiple labels (214, 216 and 218) to be removed by the de-labelling process.

[00265] In the embodiment shown, the front label 114, the rear label 116 and the neck label 118 are all to be removed, however, in contrast to the embodiment described in Example 1 where the bottle is placed into a single station for the removal of labels, in this embodiment the bottle is placed into three separate stations, each of which is devoted to the removal of a specific label type.

[00266] It will be appreciated that in this embodiment, the process may also be adjusted to remove labels selectively. The process may be adjusted to remove one or more labels, in any desired combination. For example, there may be a desire to remove only the rear label 216 on the bottle, and still retain the front label 214 and the neck label 218.

[00267] As described previously, the labels 214, 216 and 218 are typically paper-based labels, that may or may not be further laminated with a plastic covering, or be metallized paper labels. However, the process as described herein is also suitable for the removal of non-paper labels, for example synthetic labels made from plastic or labels made from metal foils.

[00268] As described previously, in the setting where a large number of wine bottles are to be de-labelled, typically the process begins with the unpacking of the bottles to be de-labelled from a container/carton, and the bottles placed onto an in- feeder conveyer system (not shown). The bottles are then conveyed to the de-labelling part of the device 220, indexed and clamped in the first station.

[00269] In the embodiment shown, the bottle is indexed in the first station and held on a base plate 220. Rotation of the base plate is achieved using a rotating spindle 222 driven by a controllable drive motor 224. The bottle 212 is clamped by way of a top clamp 226, the height of which may be adjusted using a hydraulic height adjustor 228, driven by a hydraulic unit 230. As such, the bottle 212 may be held in place and rotated for removal the type of label specific for that station, being the front label.

[00270] In the embodiment shown, the device 210 comprises at the first station two nozzles 234 and 236, which are used for removal of the front label. The jets or nozzles 234 and 236 are controllable, and may be turned off or on.

[00271] In the embodiment shown, a mixture 238 of dry ice pellets 240 and compressed air 242 is delivered via a pipe 244. Typically, a pressure of 200 psi of compressed air and a dry ice pellet size of 3 mm, in conjunction with a flow rate of the dry ice of 30 kg per hour, is suitable for removal of the front label from the wine bottle 212 by directing the gaseous mixture at the front label under pressure.

[00272] Once the bottle 212 has been positioned in place in the first station, for the removal of the front label 214, jets 234 and 236 are activated by opening of valves 248 and 250. Opening of the valves 248 and 250 permits the mixture to flow through jets 2 and 3 (234 and 236 respectively) and the gaseous mixture under pressure 252 to be directed at the front label on the bottle 212.

[00273] At the same time, the bottle 212 is rotated by means of rotation of the base plate 220. The bottle 212 can either be rotated into a specific position for removal of the label or the bottle rotated through the gaseous mixture. In this case, typically, a rotation cycle time of 15 seconds is used per bottle for de-labelling purposes. The mixture 252 (of dry ice pellets and compressed air) is ejected from the jets and directed towards the bottle 212.

[00274] The action of the mixture 252 under pressure, in conjunction with the rotation of the bottle to bring the front label 214 into contact with the mixture 252, results in removal of the front label 214 and the adhesive associated with that adhered label.

[00275] Once the cycle has been completed, the bottle 212 is automatically moved from the first station to the second station for removal of the rear label 216, and which is subsequently shown in Figure 3.

[00276] In the embodiment shown, the bottle 312 is then indexed into the second station and held on a base plate 320. Rotation of the base plate is achieved using a rotating spindle 322 driven by a controllable drive motor 324. The bottle 322 is clamped by way of a top clamp 326, the height of which may be adjusted using a hydraulic height adjustor 328, driven by a hydraulic unit 330. As such, the bottle 312 may be held in place and rotated to removal the label specific for that station, being the rear label.

[00277] The device or apparatus 310 comprises at the second station one nozzle 336, which is used for removal of the rear label. The jet or nozzle 336 is controllable, and may be turned off or on.

[00278] In the embodiment shown, a mixture 338 of dry ice pellets 340 and compressed air 342 is delivered via a pipe 344. Typically, a pressure of 200 psi of compressed and a dry ice pellet size of 3 mm, in conjunction with a flow rate of the dry ice of 30 kg per hour, is suitable for removal of the rear label 316 from the wine bottle 312 by directing the gaseous mixture at the rear label under pressure.

[00279] Once the bottle 312 has been positioned in place in the second station, for the removal of the rear label 314, jet 336 is activated by opening of valve 550. Opening of the valves 350 permits the mixture to flow through jet 3 (336) and the gaseous mixture under pressure 352 to be directed at the rear label 316 on the bottle 312. [00280] At the same time, the bottle 312 is rotated by means of rotation of the base plate 320. Once again, the bottle may be rotated into a specific position suitable for removal of the label or the bottle can be rotate through the gaseous mixture. Typically, a cycle time of 15 seconds is used per bottle for de-labelling purposes. The mixture 352 (of dry ice pellets and compressed air) is ejected from the jet and directed towards the bottle 312.

[00281] The action of the mixture 352 under pressure, in conjunction with the rotation of the bottle to bring the rear label 313 into contact with the mixture 252, results in removal of the rear label 314 and the adhesive associated with that adhered label.

[00282] Once the cycle has been completed, the bottle 312 is automatically moved from the second station to the third station for removal of the neck label 318, and which is subsequently shown in Figure 4.

[00283] In the embodiment shown, the bottle 412 is then indexed into the third station and held on a base plate 420. Rotation of the base plate is achieved using a rotating spindle 422 driven by a controllable drive motor 424. The bottle 422 is clamped by way of a top clamp 426, the height of which may be adjusted using a hydraulic height adjustor 428, driven by a hydraulic unit 430. As such, the bottle 412 may be held in place and rotated to removal the label specific for that station, being the neck label.

[00284] The device or apparatus 410 comprises at the third station one jet or nozzle 432, which is used for removal of the neck label. The jet or nozzle 432 is controllable, and may be turned off or on.

[00285] In the embodiment shown, a mixture 438 of dry ice pellets 440 and compressed air 442 is delivered via a pipe 444. Typically, a pressure of 200 psi of compressed air and a dry ice pellet size of 3 mm, in conjunction with a flow rate of the dry ice of 30 kg per hour, is suitable for removal of the neck label 416 from the wine bottle 412 by directing the gaseous mixture at the neck label under pressure.

[00286] Once the bottle 412 has been positioned in place in the third station, for the removal of the neck label 418, jet 432 is activated by opening of valve 446. Opening of the valve 446 permits the mixture to flow through jet 1 (432) and the gaseous mixture under pressure 452 to be directed at the neck label 418 on the bottle 412.

[00287] At the same time, the bottle 412 is either rotated into a specific position or rotated continuously through the stream, by means of rotation of the base plate 420. Typically, a rotation time of 15 seconds is used per bottle for de-labelling purposes. The mixture 452 (of dry ice pellets and compressed air) is ejected from the jet and directed towards the bottle 412.

[00288] The action of the mixture 452 under pressure, in conjunction with the rotation of the bottle to bring the neck label 418 into contact with the mixture 452, results in removal of the neck label 418 and the adhesive associated with that adhered label.

[00289] Once the cycle has been completed, the bottle 412 is automatically unloaded from the de-labelling device 410 and automatically conveyed to a buffer/drying station (not shown), utilizing blown air and buffing wheels. Once the bottle 412 is dried and buffed, the bottle 412 may then be automatically conveyed into a labelling machine, where one or more new labels are applied, in accordance with the labelling requirements. Labelled bottles are them conveyed automatically via a conveyer system to a packing area and the newly labelled bottles repacked into cartons.

[00290] It should be noted that the process and device described in this embodiments also results in the removal of the labels without the need for pre -treatment of the labels by soaking in water or by treatment with another type of solvent.

[00291] Further, aside from the efficient and convenient removal of the labels from the bottle 412, the method and de-labelling device described also results in substantial removal of the adhesive/glue, thereby removing the need post treat the bottle after, including removing the need to post-treat the bottle with any additional soaking or other treatment with other solvent.
