Definitions

  • the invention relates to a labeling machine for bottles with a turntable arranged between an inlet star and an outlet star, which has a rotatably mounted, hood-free bottle carrier on its base with storage spaces for the bottles arranged on its circumference, to which stationary brushing elements are arranged laterally on a section of their circulation path are assigned and each consist of a driven turntable and a centering head supported by a radial arm of a cylinder mounted in the bottle carrier and adjustable by an actuator, both the rotary drives of the turntables and the actuators of the cam drives, each with a common fixed in the substructure Curve for the cam drives of the rotary drives on the one hand and the cam drives of the actuators on the other.
  • Labeling machines of this and similar types with hood-free bottle carriers have been around for many decades known (DE-A-391 729; FR-A-1,294,574).
  • Such labeling machines have the advantage of free access for the operators compared to other labeling machines with a hood arranged above the bottle carrier, which carries the centering heads and their drives.
  • the vast majority of the labeling machines used in practice today have a hood over the bottle carrier, because the common height adjustment of the centering heads simplifies the format changeover, especially in the case of a large number of recording spaces.
  • each column is mounted in a guide sleeve built on the bottle carrier.
  • the brushing elements are arranged both on the inner and on the outer side of the circulation path of the bottles. While the fixed fixing of the outer brushing elements is possible without problems, the fixed fixing of the inner brushing elements causes problems because of the rotating parts in the interior of the carrier.
  • One possible solution is not specified in the prior art.
  • the invention has for its object to provide a labeling machine of the type mentioned with a simple design.
  • the labeling machine according to the invention has a simple structure, because an independent guide element built on the bottle carrier is not provided for each column, but a common guide body; which not only serves as a guide for the columns, but also as a support ring for the brushing elements. Since the carrier ring also extends over the area between the inlet and outlet star, a holder can be brought out of the bottle carrier in this area without the risk of collision with moving parts of the bottle carrier, over which the carrier ring is held so that it cannot be held rotates together with the bottle carrier and the guide body built thereon, on which it is rotatably mounted.
  • the engagement members of the cam gears of all actuators each have a transmission member with a radial arm with the column connect. Because of the lever transmission of the radial boom, the pivoting position of the boom carrying the centering head can be guided precisely with low forces.
  • the control curve has a larger diameter than the running circle of the Pillars. The required positioning movements are therefore distributed over a larger curve and thus result in a comparatively small area load.
  • a power control which is independent of the power is provided for the movement of the centering heads, which consists in the fact that the curve of the cam gears of all actuators is a cylinder cam designed as a groove curve, on the two flanks of which the engagement members are guided and that for each An engaging member is provided with an axial guide between the engaging member and the bottle carrier, the axial guide in particular consisting of an axial groove and an engaging member.
  • a return spring is deliberately dispensed with, in order to ensure the required movement of the centering head for each performance.
  • the secondary task in the prior art of the return spring to compensate for height tolerances of the bottle can be achieved in the invention, on the one hand, by a flexible pressure cushion in the centering head , which is provided for the all-round pressing of a film blank surrounding the bottle head, but above all by a resilient support of the centering head in the boom.
  • the spring must be designed for the return of the centering head; but since its mass is small compared to the total mass of the centering head, boom, pillar and engagement member and the travel path provided only for the purpose of tolerance compensation is not particularly large spring.
  • the axial position of the boom on the column is adjustable.
  • the axial position of the boom is preferably determined by a stop supported on the free end face of the column.
  • Each boom extension should be interchangeable. This facilitates the changeover from one bottle size to another bottle size, because then only one stop set needs to be exchanged for another stop set for a conversion. It is structurally particularly simple if the stop is designed as a sleeve which is closed at one end by a base and which can be plugged onto the column.
  • the carrier ring for the brushing elements is axially fixed by a releasable holding element on the guide body. After loosening the holding element, the carrier ring can then be axially removed from the guide body. For such a format changeover, however, it is also necessary that the cantilevers supporting the centering heads are dismantled. This is necessary anyway if the bottles are not only different in diameter but also in height.
  • a protection of the drives from water and dirt can be easily achieved according to an embodiment of the invention in that the base and the bottle carrier form two shells receiving the drives, which are sealed at their outer, opposite edges, in particular by a labyrinth seal. With this configuration, the required freedom of movement between the base and the bottle carrier is retained.
  • the labeling machine shown in FIG. 1 has an inlet star 1, an outlet star 2 and a rotary table 3 arranged between them.
  • the inlet star 1 and the outlet star 2 have pockets 5, 6 on their circumference for receiving the bottles 4 to be labeled, so that the bottles 4 are held in the pockets 5, 6, sheet guides 7 a, 7 b are one between the inlet and outlet star 1 , 2 arranged guide element 7 assigned.
  • the rotary table 3 consists of a two-part base 9a, 9b built on a table top 8 and a bottle holder 10 rotatably mounted on the base 9a, 9b.
  • the two parts 9a, 9b of the lower house can be adjusted independently of one another in their rotational positions on the table top 8.
  • Turntables 11 are mounted in the bottle carrier.
  • the turntables 11 are assigned centering heads 12 which are variable in relation to the turntables 11 by actuators to be described in more detail below.
  • the turntable 11 and the Centering heads 12 form receiving spaces for the bottles to be labeled and clamp them axially, while the labels are transferred to them from a labeling station (not shown in the drawing) on the outer circumference of the rotary table 3.
  • Cam-controlled drives are assigned to both the turntables 11 and the centering heads 12.
  • each turntable 11 is connected via a drive shaft 13, usually with an intermediate transmission gear, to a lever arm 14, which carries two cam rollers 15 which engage as an engagement member in a flat, fixed groove curve 16 of the outer part 9a of the substructure 9a, 9b.
  • the course of the groove curve 16 is designed such that when the bottle carrier 10 rotates, the bottle 4 to be labeled is rotated at stations arranged along the path in such a way that a label is transferred to it and placed on the circumference of the bottle 4.
  • the centering head 12 is supported by a radial arm 17. For this purpose, it is mounted axially displaceably with a guide pin 18 in a guide bush 19 against the force of a spring 20.
  • the spring 20 is compressed in order to exert the axial clamping force and to effect a tolerance compensation.
  • the boom 17 has at the end facing away from the centering head 12 a guide bushing 21 which can be clamped onto a column 23 by means of a clamping bolt 22.
  • a stop 25 in the form of a sleeve which is closed at one end by a base 26 is locked in the guide bushing 21 by means of a bayonet lock.
  • the bottom 26 rests on an end adjusting screw 27 of the column 23.
  • This adjusting screw 27 is used for fine adjustment, while the axial length 25 of the sleeve-shaped stop Position of the sleeve 21 on the column 23 is basically determined.
  • the columns 23 of all centering heads 12 are mounted in a common central guide body 28 which is part of the bottle carrier 10.
  • the columns 23 are axially displaceable in this guide body 28.
  • Their axial position is determined by a fixed groove curve 29, which is arranged in the substructure 9 and is designed as a cylinder curve.
  • an engagement member 30 is guided on both flanks of the groove curve 29.
  • a simple cam roller is shown.
  • the engagement member 30 can be designed as a double cam roller like the cam roller.
  • the engagement member 30 is carried by an angular transmission member 31, the radial arm 31a of which is rigidly connected to the column 23 and carries a further engagement member 32 in the form of a sliding block which engages in an axial groove 33 which is formed in the bottle carrier 10.
  • the engagement member 32 and the axial groove 33 form an axial guide for the transmission member 31 and prevent rotation of the column 23. Because of the radial arm 31a, the diameter of the groove curve 29 is larger than the diameter of the concentric circle, which is determined by the columns 23. This results in a low curve load.
  • Another advantage of the radial boom is that only small forces are required to move the centering element because of the lever arm translation. 12 to keep in the correct swivel position.
  • This labyrinth seal 34 largely prevents the entry of dirt and water into the interior of the shells.
  • the central guide body 28 not only serves the columns 23 as an axial guide, but brushing elements 35 as a rotary bearing.
  • it has on its outer circumference as a rotary bearing 36 a bearing bush having a two-part collar, on which a carrier ring 37 is rotatably mounted.
  • the rotary bearing 36 and thus also the carrier ring 37 held between the collars is fixed on the guide body 28 by means of a releasable annular holding element 42.
  • the carrier ring 37 has a base 38 with axial plug pins 39, on which the brushing elements 35 are attached by means of a support element 40.
  • the carrier ring 37 is fixed to the guide element 7 between the inlet and outlet star 1, 2 with a holder 41 which is led out of the area of the receiving places 11, 12 so that the carrier ring 37 does not rotate when the bottle carrier 10 rotates.
  • the radial arms 17 with the centering heads 12 are removed from the columns 23 and the stops 25 are exchanged in accordance with the new height of the bottles.
  • the carrier ring 37 can also be pulled axially from the guide body 28 after loosening the annular holding element 42 and exchanged for another carrier ring which is equipped with other brushing elements.
  • such a disassembly is generally not necessary for a format adaptation to different diameters of the bottles, because the brushing elements 35 can be exchanged with their support element 40 when the carrier ring 37 is mounted.
