Definitions

  • the present innovation relates to a reel transfer unit.
  • the present innovation may be advantageously, but not exclusively, used to transfer, i.e. to load or feed, automatically reels of labelling material to the labelling module of a labelling machine configured to apply labels onto articles, in particular containers designed to contain a pourable product, preferably a food product.
  • the bottling of pourable food or non-food products inside respective containers is usually accompanied by the labelling of these containers with respective labels, in the form of thin bands which are obtained from a strip of labelling material, during a labelling process.
  • the strip of labelling material is wound onto one or more storage reels which typically have a disc-like form, with a height substantially equal to the transverse extension of the strip.
  • the labelling of the container is performed before, during or after the filling thereof, by means of special labelling machines.
  • Labelling machines which are configured to prepare, transport and apply, during a labelling process, labels onto respective containers designed to be filled with a pourable product are known.
  • a succession of containers is moved forwards, along a predetermined travel path, towards a labelling module of the labelling machine configured to label each container.
  • the strip of labelling material is firstly unwound from the respective storage device and then fed, along a predetermined feeding path, to a cutting device, typically a cutting blade, which is configured to separate the strip into a succession of single labels which have the same length.
  • a cutting device typically a cutting blade
  • the labelling module further comprises a label transfer device, typically a vacuum drum which is configured to receive each label, retain it on an outer surface thereof by means of suction and apply it onto a respective container, in an application station.
  • a label transfer device typically a vacuum drum which is configured to receive each label, retain it on an outer surface thereof by means of suction and apply it onto a respective container, in an application station.
  • a layer of glue is spread on an inner side of each label, namely on its rear side, namely the side which is intended to cooperate by means of contact, in particular to be pressed, onto the respective container, after application.
  • the transfer or loading operation is performed by means of a transfer (or loading) unit usually comprising one or more robotic arms configured to remove the reels from the respective stack and release them to the labelling module.
  • a transfer (or loading) unit usually comprising one or more robotic arms configured to remove the reels from the respective stack and release them to the labelling module.
  • a transfer unit of the known type comprises one or more storage members, for example vertical supports, each consisting of a column supported in a vertical position by a base (for example a tripod); the reels are secured to the support by inserting the column concentrically inside the central hubs of the respective reels. In this way, stacks of concentric reel are obtained, said stacks being positioned, for example by an operator, in the vicinity of the labelling module.
  • Each reel is then removed from the respective stack by means of the aforementioned robotic arm, for example by means of engagement of a respective gripping device mounted on the robotic arm with the associated central hub of the reel.
  • the object of the present innovation is to provide a unit for transferring reels of labelling material, which is very reliable and has a low cost and which is able to overcome at least some of the aforementioned drawbacks associated with the units for transferring reels of labelling material of the known type.
  • this object is achieved by a transfer unit according to Claim 1.
  • 1 denotes in its entirety a labelling machine (shown in schematic form and with parts removed for greater clarity) configured to handle a labelling material in an automated labelling process.
  • the labelling machine 1 forms part of a plant for packaging pourable products and is configured to apply labels 2 obtained from a strip 3 of labelling material onto articles.
  • the articles consist of containers 4, for example bottles, cans or the like, which are made of plastic, metallic or glass material, able to contain (namely be filled with) a pourable product, preferably a food product.
  • the labels 2 applied are glued labels, namely portions of labelling material of predefined length, which are cut from the strip 3 of labelling material and then covered with glue. These cut and glued labels 2 are then transferred and applied onto the outer surface of the respective containers 4.
  • the labelling machine 1 comprises essentially:
  • the strip 3 is initially wound - and stored - on respective storage reels 6 having a disc-like form and a height substantially equal to the transverse extension of the said strip 3.
  • the labelling module 13 comprises essentially:
  • the vacuum drum 10 has a substantially cylindrical-toroidal lobe-shaped form.
  • the drum 10 receives in sequence, during use, the labels 2 which have been cut beforehand by the cutting blade 9, retains the labels 2 by means of suction on its side surface and, after a rotation through a given angle about the axis X, releases these labels 2 in the application station A, so that they are applied onto the respective containers 4, in a manner known and not described in detail.
  • the labelling module 13 comprises, furthermore, a glue application device 11, for example a glue roller, configured to apply a certain predetermined amount of glue onto each label 2, before the latter is applied onto the associated container 4.
  • a glue application device 11 for example a glue roller, configured to apply a certain predetermined amount of glue onto each label 2, before the latter is applied onto the associated container 4.
  • the application device 11 is configured to spread a layer of glue on an inner side of each label 2.
  • inner side of the label 2 is understood as being the rear of the label 2, namely the side intended to cooperate by means of contact, namely to be pressed, onto the side surface of the respective container 4, after application.
  • the inner side therefore forms the non-visible part of the label 2 after application.
  • the labelling machine 1 further comprises a transfer unit 12 configured to feed - i.e. to transfer or load - in sequence the reels 6, in particular at least one reel 6 at a time to the labelling module 13.
  • the transfer unit 12 is configured to position one reel 6 at a time on each shaft 7 of the labelling module 13 and to remove the empty reels 6 from the said shafts 7.
  • the transfer unit 12 comprises:
  • each of the two shafts 7 defines an aforementioned release station R.
  • the support member 14 is arranged at the rear of the labelling module 13, in particular on the side of the labelling module 13 opposite to that of the carousel 5.
  • the support member 14 comprises a vertical column 17 engaging, during use, with the central of hubs of the stacked reels 6 and a disc-like base 18 mounted slidably on the column 17 and supporting above it, during use, the stack 15.
  • the reels 6 are stacked vertically on the disc-like base 18 with their central hubs engaged by the vertical column 17.
  • the robotic arm 16 comprises a gripping member 20 configured to remove at least one reel 6 from the stack 15, at the gripping station G, and to release it at the corresponding release station R, namely onto the corresponding shaft 7.
  • the stack 15 when the stack 15 is located at the gripping station G, it is arranged underneath the robotic arm 16, in particular underneath the gripping member 20.
  • the gripping member 20 comprises vacuum suction means for removing and retaining one reel 6 at a time.
  • the gripping member 20 is defined by a substantially circular plate comprising, on its bottom surface facing, during use, the stack 15 (and therefore directed downwards), a plurality of holes (not shown); these holes are connected in fluid communication with a vacuum source (known per se and not shown) designed to generate a sucking action in the region of the said holes.
  • the gripping member 20, and therefore the robotic arm 16 is able to remove and retain in sequence the reels 6, in particular one reel 6 at a time.
  • the sucking action is interrupted and the reel 6 is released to the corresponding shaft 7; in this condition the central hub of the reel 6 is engaged by this shaft 7 so that the shaft 7 itself rotatably supports the reel 6.
  • the holes extend radially over the entire bottom surface of the gripping member 20; in this way it is possible to avoid the undesirable separation of the strip 3 from the reel 6 during transfer from the gripping station G to the associated release station R.
  • the labelling module 13 comprises, on each shaft 7 of the means for raising the reels 6, in particular fork members 21 movable vertically between:
  • the fork members 21 are slidably connected to respective vertical guides 30 which are fixed onto the labelling module 13.
  • the empty reels 6 are transferred, by means of the robotic arm 6, to a special collection device 22 (schematically shown).
  • the support member 14 is movable horizontally, during use, at least from a remote position, where the reels 6 are arranged stacked vertically on the said support member 14, to the gripping station G, where the transfer unit 12 is configured to eliminate the vertical distance between the stack 15 and the robotic arm 16, namely between the stack 15 and the bottom surface of the gripping member 20.
  • the transfer unit 12 comprises a trolley 23 carrying the support member 14, in particular carrying on top of it the support member 14 and movable horizontally at least from the remote position to the gripping station G.
  • the column 17 is fixed to the trolley 23 and therefore transported, during use, by the trolley 23.
  • the trolley 23 is provided with wheels and the transfer unit 12 further comprises a guide rail 24 extending horizontally at least from the remote position to the gripping station G and configured to seat slidably the trolley 23, in particular the wheels of the trolley 23.
  • the transfer unit 12 further comprises a control unit 25 configured to control the sliding movement of the trolley 23 along the guide rail 24 at least from the remote position to the gripping station G. Consequently, the trolley 23 defines an automatic robotic trolley.
  • the trolley 23 could be moved manually by an operator.
  • the trolley 23 When the trolley 23 is located in the remote position, it carries the support member 14 which supports, in turn, a plurality of reels 6 organized in a vertical stack 15, as specified above.
  • the trolley 23 is operated by the control unit 25 so as to move from the remote position to the gripping station G where the stack 15 is arranged underneath the gripping member 20 of the robotic arm 16.
  • the transfer unit 12 eliminates the vertical distance between the stack 15 and the gripping member 20.
  • the transfer unit 12 comprises raising means designed to move vertically the stack 15 when the support member 14 is located at the gripping station G and therefore when the stack 15 is located underneath the gripping member 20.
  • the raising means comprise a vertical guide 26 and a lifting fork 27 slidably engaged with the vertical guide 26.
  • the fork 27 is configured to cooperate by means of contact with the disc-like base 18, more particularly with a bottom surface of the disc-like base 18.
  • the fork 27 raises, during use, the disc-like base 18 so as to move vertically the stack 15 itself and bring the first reel 6 (that arranged highest) in the stack 15 within the reach of the gripping member 20.
  • the fork 27 is operated by the control unit 25 so as to move downwards, so that the reel 6 to be transferred remains gripped by the said gripping member 20 and so that the stack 15 does not interfere with the subsequent movement of the gripped reel 6.
  • the fork member 27 When the next reel 6 must be transferred, the fork member 27 will be operated so as to move again upwards, thus bringing the new first reel 6 within the reach of the gripping member 20.
  • control unit 25 causes the displacement of the trolley 23 from the gripping station G to the remote position.
  • the robotic arm 16 is fixed pivotably, in particular rotatably, to a rear portion of the labelling module 13.
  • the robotic arm 16 comprises:
  • the bar element 29 is arranged perpendicularly with respect to the axis Y.
  • the robotic arm 16 is configured to move the gripping member 20 along a substantially circular gripping path W concentric with the axis Y and passing through the gripping station G and the release stations R.
  • the robotic arm 16 is fixed to the ground supporting the labelling module 13, the transfer unit 12 and the carousel 5.
  • the gripping member 20 is movable vertically towards/away from the support member 14 when the support member 14 is in the gripping station G.
  • the spindle 28 of the robotic arm 16 is extendable/retractable along the axis Y; since the bar element 29 is mounted integrally with the spindle 28, it causes a corresponding vertical movement of the gripping member 20.
  • the gripping member 20 is mounted so as to be movable with the bar element 29, for example by means of a coupling extendable telescopically in the vertical direction.
  • the gripping member 20 is able to reach the aforementioned first reel 6 in the stack 15 and grip it, at the gripping station G.
  • the transfer unit 12 comprises at least two support members 14 each configured to support a respective plurality of reels 6 organized vertically in respective stacks 15.
  • At least two gripping stations G1 and G2 are defined and passed through by the gripping path W defined, during use, by the gripping member 20 of the robotic arm 16 about the axis Y.
  • the trolley 23 is operated by the control unit 25 so as to move from the remote position to the gripping station G, or is already located in the gripping station G. Moreover, the robotic arm 16 is operated to move into the gripping station G (situation shown in Figure 2a ).
  • the labelling module 13 so as not to interrupt production, draws material from the full reel 6 which has already been loaded onto the other one of the shafts 7 by means of a system for splicing the strip 3, known per se and not described in detail.
  • the robotic arm 16 is operated to move along the path W towards the associated release station R in order to pick up the empty reel 6, unload it onto the collection device 22 ( Figure 2b ) and move towards the gripping station G.
  • the fork 27 raises the stack 15 and the gripping member 20 grips the new reel 6 from the stack 15.
  • the gripping member 20 moves down vertically towards the stack 15 in order to pick up the new reel 6, as specified above.
