Definitions

  • the invention relates to a winding machine according to the preamble of claim 1.
  • each packaging container including the label
  • a label winding station In the previously known machines for applying labels to packaging containers for food and beverages, each packaging container, including the label, is brought into a label winding station.
  • an adhesive is either applied to the packaging container or along a front edge of the label, the front edge of the label then being pressed against the packaging container in order to attach this edge of the label to the packaging container.
  • the packaging container is then rotated so that the rest of the label is wrapped around it, with adhesive then being applied to the rear edge of the label in order to connect this edge to the front edge in an overlap area. Since the label is bonded to the packaging container, its subsequent removal from it is a difficult operation.
  • a machine for attaching a ring around a cylinder body for example for banding cigars in the cigar industry is known, in which a plurality of winding stations are arranged along the circumference of a circular disc rotatable about a horizontal axis, each of which has a triangular band arrangement.
  • the triangular base sides of the band arrangements run approximately tangentially to the disk, the corners of the band arrangement being formed by pins or rollers over which the band is guided.
  • the tip of each such triangle is connected to a central region of the disc via a spring, so that a minimum tension is maintained in the band.
  • a feed station for labels, which are coated at one end region with an adhesive, is provided peripherally to the said disk.
  • the objects to be wrapped are pressed in the area of the feed station with the help of a stamp against the base of a triangular belt arrangement, a label being located between the belt and the object.
  • the object is surrounded by the band over a circumferential angle of approximately 180 ° during the pressing against the band arrangement, whereby at the same time the label is bent around the object in such a way that its ends are parallel to one another and perpendicular to one through the corners of the base of the triangular band arrangement definable line.
  • the left end of the label is first bent by the oscillatingly driven folding fingers and then the right end of the label, which is provided with an adhesive, is bent around the object, so that its ends are glued together.
  • the label is first wrapped around the object by means of the winding machine according to the invention, so that the printing substance is transferred to its surface.
  • the label is then removed from the object, leaving behind the printing substance forming an imprint. Due to the precise guidance of the material web, an exact overlap of the end regions to be glued together is also possible, as a result of which it is subsequently possible to peel off easily those labels which carry a transferable printing substance. This peeling off of the label would be considerably more difficult if adhesive got between the label and the object.
  • a label can thus be wrapped around an object and glued in the region of its overlapping ends without being connected to the object itself by gluing. In the above-mentioned overlap area, only the end areas of the label are connected to one another, so that the label is held firmly around the object.
  • the label can then be stripped from the object, for example by using a compressed air jet stripping method.
  • the subclaims 2 to 6 are directed to the structural design of a single winding station and the subclaims 7 to 13 to the complete machine system, which is composed of a plurality of winding stations.
  • the machine system has a feed station for the material webs, a feed station for the objects to be wrapped, and a delivery station for the wrapped objects.
  • the subclaims 14 and 15 relate to particularly advantageous applications for the winding machine according to the invention.
  • the winding machine to be described is used to wrap labels that carry transferable printing substances in order to wrap packaging containers, namely cans, on which a receiving surface is located.
  • packaging containers namely cans
  • the can and the label are further treated to effect the transfer of the printing substance from the substrate of the label to the can .
  • the substrate is then removed from the can, the printing substance forming an imprint remaining thereon. In order to ensure all-round printing and to make it easier to remove the substrate, it is extremely important that no adhesive gets between the label and the can.
  • the machine shown in FIG. 1 has a main turntable 10 which is rotatably mounted on a main shaft 12.
  • the main rotary table 10 can be rotated counterclockwise about the main shaft 12 by means of an arrangement (not shown in the drawing) consisting of a motor and a transmission.
  • the main turntable 10 carries a plurality of labeling stations 14, which are arranged around the axis of the main shaft 12 with the same winding spacing.
  • Each labeling station 14 includes a winding tape device 16, a circular support plate 18 for a packaging container, a centering mandrel (not shown in the drawing) for a packaging container and a pair of label gripping devices 20, 22.
  • a feed station 24 for the packaging containers serves to transfer the packaging containers from a feed conveyor belt 26 to the main turntable 10.
  • the feed station 24 also serves to place the packaging containers arriving on the feed conveyor belt 26 at a predetermined distance and to place each individual packaging container on one of the support plates 18 the main turntable 10 on which the respective packaging container is held by a mandrel 86 shown in FIG. 7 during the rotation of the main turntable 10 beyond the feed station 24.
  • a label feed station 28, which - seen in the direction of rotation of the main turntable 10 - is arranged locally in front of the feed station 24, serves to supply the label gripping devices 20, 22 of each labeling station 14 with labels, which are removed from a label magazine 30 as soon as the label gripping devices 20, 22 come on the label feed station 28 are passed.
  • a - viewed in the direction of rotation of the main rotary table 10 - arranged behind the feed station 24 for packaging containers 32 serves to successively remove the individual packaging containers from the rotary table 10 and transfer them from the latter to a conveyor belt 34.
  • Each labeling station 14 is actuated during its passage from the feed station 24 to the delivery station 32 in such a way that a label is wrapped around the respective packaging container.
  • the feed station 24 will be described in detail below.
  • the packaging containers 8 arriving on the feed conveyor belt 26 are at an uneven distance from one another.
  • the packaging containers 8 are aligned in alignment by means of a guide rail 36 which extends along a side edge of the feed conveyor belt 26.
  • a uniform distance between the packaging containers 8 is set by means of a feed screw 38, which is arranged on the opposite side edge of the feed conveyor belt 26.
  • the feed screw 38 has a helically wound groove 38a. Any packaging container 8 that is inserted into the space between the guide rail 36 and the feed screw 38 can only be inserted into this space by engaging the groove 38a. In this way, a uniform spacing of the packaging containers 8 is ensured, which corresponds to the slope of the helical groove 38a.
  • a rotatable star wheel 40 At the end of the space between the feed screw 38 and the guide rail 36 - as seen in the conveying direction of the feed screw 38 - there is a rotatable star wheel 40.
  • the star wheel 40 has a total of four recesses 40 a, which are arranged at equal angular intervals on its circumference. Both the star wheel 40 and the feed screw 38 are replaced by the same one driven motor-gear arrangement, not shown in the drawing, which simultaneously drives the main turntable 10.
  • the relative angular positions of the star wheel 40 and the feed screw 38 are set such that a packaging container which is led out of the above-mentioned space can always be inserted into a recess 40a.
  • Each recess 40a of the star wheel 40 is provided with a plurality of vacuum openings, not shown in the drawing.
  • a vacuum system not shown, to which a series of valves, also not shown, are assigned, a vacuum is generated which is switched on in a recess 40a at the moment when a packaging container 8 enters the recess from the above-mentioned space and which in the Is switched off at the moment in which the respective packaging container has been rotated by the star wheel 40 into a position immediately above a support plate 18 of a corresponding labeling station.
  • a packaging container 8 is held in the corresponding recess 40a by the suction force of the vacuum, removed from the feed conveyor belt 26, moved in the direction of the main turntable 10 and only released at this moment as soon as it has arrived directly above a support plate 18. Since the main turntable 10 and the star wheel 40 have a common drive, the exact positioning of the recesses 40a with respect to the support plates 18 can be synchronized.
  • the label feed station 28 will now be described in detail.
  • the label feed station 28 comprises an auxiliary turntable 42.
  • this secondary turntable 42 there are four arc-shaped label supports 44, which are each fastened to support shafts 46.
  • the secondary turntable 42 can be rotated clockwise so that each label support 44 moves along a label magazine 30 in order to take up labels one after the other and feed them to the label gripping devices 20, 22 of a corresponding labeling station 14.
  • an adhesive application roller 48 in front of the label magazine 30.
  • This adhesive application roller is continuously supplied with an adhesive, with a doctor blade 50 ensuring that a film of uniform thickness is maintained on the adhesive application roller 48.
  • the adhesive that has been removed by the doctor blade 40 is returned to the adhesive applicator roller 48, which is rotated counterclockwise.
  • Each label support 44 is provided in its outer surface with a plurality of vacuum slots 52a to 52d extending in the longitudinal direction thereof.
  • the slots 52a to 52d are connected via a cam-controlled valve group to a vacuum source, not shown in the drawing.

  • the rear edge of the label support 44 is provided with a projecting rib 54.
  • the label supports 44 are arranged in such a way that when the secondary turntable 42 rotates, only this rib 54 comes into contact with the adhesive application roller 48. Thus, each time a label support 44 is guided past the adhesive application roller 48, only the rib 54 is coated with adhesive.
  • the label magazine 30 is in the form of a magazine housing 58 which contains a label supply.
  • a pair of pressure plates 60, 61 which is connected to a system (not shown) consisting of a torsion spring and a coil, of rollers and a cable, serves to press the labels towards the front of the label magazine 30.
  • Each of the pressure plates 60, 61 can be retracted independently of the other to allow refilling of labels during the operation of the winding machine. This is shown in detail in Fig. 3a.
  • the foremost labels are held in the magazine housing 58 by wedge-shaped knives 64 which bear against the upper and lower edges of the labels and by spring-loaded fingers 66 which bear against the front and rear edges of the respective label. This can be seen from FIG. 4.
  • the support shaft 46 is fastened on the secondary rotary table 42 in such a way that it can execute an oscillating and at the same time a reciprocating movement in the radial direction about its own longitudinal axis. 3 shows this.
  • This movement is controlled by a number of cams, not shown, such that the moment the arcuate label support 44 approaches the foremost label of the label magazine 30, the front edge of the label support contacts the front edge of the label.
  • This is followed by a continuous application of the rest of the label support 44 to the corresponding parts of the label, until finally the rear edge of the label support 44 lies against the rear edge of the label.
  • the vacuum slots 52 (a-d) are vacuumed so that a label is pulled out from under the fingers 66 and thereby moves over the knives 64 which make corresponding incisions in the upper and lower edges of the label.
  • the vacuum is maintained, with the label being fed to the main rotary table 10 during the further rotation of the secondary rotary table 42, in order to be taken over here by the label gripping devices 20, 22 .
  • the rib 54 is brought into firm contact with the rear edge of the label, so that this rear edge is coated with the adhesive which has been taken up by the adhesive application roller.
  • the feed screw 38 is assigned a sensor by means of which it can be determined whether a packaging container is missing in the helical groove 38a. If the absence of a packaging container is discovered in this way, an air cylinder (not shown) is actuated by means of a signal emitted by the sensor. The label magazine 30 is temporarily held back by this cylinder, so that no label is fed to the corresponding labeling support.
