Definitions

  • the invention relates to a labeling machine according to the preamble of claim 1.
  • the angular position of the stamp must be precisely defined during the labeling process. This applies, for example, if the stamp has a flattened contact surface on one side for a label end protruding upward above the label object or is provided with a controllable gripper finger for a label or has an opening which enables a label to be applied to the top of the label object , or if the surface of the labeling object gripped by the stamp is eccentric to the axis of rotation of the plate. In such cases it is known to provide the stamp with its own rotating device. Such a labeling machine is described in DE-A-38 23 471.
  • the invention is concerned with the problem of making the rotary device for the stamps particularly simple and inexpensive in a generic labeling machine.
  • the stamps are only controlled directly by the rotating device when they are lifted off the labeling objects, while they are controlled indirectly by the plates when they are pressed against a labeling object.
  • This enables a particularly simple and inexpensive construction of the rotating device, which can also be easily retrofitted to labeling machines already delivered. It is usually not necessary to retrofit the rotating device when changing the rotating program for the plates; the rotating device mainly only has to ensure that the stamp assumes a predetermined starting position when it is placed on the vessel or the like. Elaborate control curves, which directly influence the stamp during the entire labeling process, are not necessary.
  • the required initial position or zero position of a stamp can be defined in the simplest way by two interacting stops, one with the stamp and the other with a fixed part of the labeling machine connected is.
  • the stops are brought into contact by a torsion spring acting on the stamp as soon as the stamp is lifted off a labeling object.
  • the stamp is then taken away from the labeling object against the torsion spring.
  • the torsion spring of the rotating device is also effective when the stamp is placed on the labeling object, but is easily run over if the dimensions are sufficiently weak.
  • the rotating device is only effective as long as the stamp has no contact with a labeling object.
  • the stamp can rotate freely in the labeling area together with the labeling object without being hindered by a torsion spring or the like.
  • the stamp has a friction lining acting on the labeling object.
  • the labeling machine shown only partially in FIGS. 1 to 4 is set up for equipping labeling objects in the form of bottles 24 with different labels. It has a rotary table 20 which rotates around a vertical axis and in which a plurality of plates 1 with a vertical axis of rotation are distributed evenly over the circumference. These are connected via a pinion 21 to a toothed segment 22 which is pivotably mounted on the rotary table 20 and which in turn engages with a cam roller 17 in a self-contained groove cam 23, formed in a fixed cam ring 16.
  • a friction lining 19 is provided on the top of the plate 1.
  • a rotary head 14 is provided at a distance from the rotary table 20, which is connected to the rotary table 20 in a rotationally fixed manner and therefore rotates together with the rotary table 20.
  • bearing blocks 13 are fastened, distributed uniformly over the circumference, one over each plate 1.
  • the sliding block 25 is guided for the purpose of securing the sleeve 9 against rotation in a vertical link 26 of the bearing block 13, while the cam roller 12 engages in a self-contained, groove-shaped lifting curve 11, formed in a fixed cam drum 27.
  • a control device for the lifting movement or the height of the sleeves 9 is formed by the lifting curve 11 and the cam rollers 12 scanning these.
  • a vertical rod 15 is mounted such that it can move vertically, a spring element 10 in the form of a compression spring with pretension being inserted between the upper end face of the rod 15 and the closed upper end face of the sleeve 9. This thus seeks to move the rod 15 downward against the plate 1 or a bottle 24 carried by it.
  • a plunger 2 is rotatably supported by means of a vertical cylindrical bearing bore, with the interposition of a hardened ball.
  • the cylindrical upper part of the stamp 2 is provided with a transverse bore in which a pin 28 is detachably held by means of a clamping spring.
  • the pin 28 engages in a corresponding annular groove in the rod 15 with play and thus releasably holds the stamp 2 on the rod 15.
  • a disk-like control cam 4 with a cylindrical jacket is formed, which is described in more detail below.
  • the lower part of the stamp 2 is designed in the manner of a centering bell and provided on one side with a vertical, corrugated flat 29.
  • a friction lining 18 is fastened to the underside of the stamp 2, in the area which comes into contact with the bottle 24 or its closure. This improves the transmission of the rotary movement from the bottle 24 to the stamp 2.
  • a holder 8 is adjustably clamped, which is designed in the upper area in the manner of a horizontal, slotted clamp with a clamping screw 30 and has an arm projecting vertically downward beyond the control cam 4.
  • a rotatable roller 5 is arranged on the holder 8, the height of which sits between the control cam 4 and the plate 1.
  • the roller 5 is arranged with the axis of rotation aligned radially to the axis of rotation of the stamp 2 such that it can touch the outer edge of the lower end face of the control cam 4.
  • This edge of the control cam 4 is designed in the manner of a one-sided stroke curve and has a recess 7 which defines a preferred zero position of the plunger 2 when it is in contact with the roller 5. Both sides of this recess 7 are followed by ramps 6 which drop downwards and which unite to form a tip on the opposite side of the control curve 4. In cooperation with the roller 5, the two ramps 6 are responsible for the return rotation of the plunger 2 to the zero position.
  • the arm 8, which projects downward, is arranged on the inside of the sleeve 9, which faces the axis of rotation of the rotary table 20, in order not to hinder the application of the labels, which is carried out from the outside by labeling cylinders (not shown) or the like.
  • the exemplary embodiment shown is a body label, a back label and a breast label which has a strip 31 projecting upward above the head of the bottle 24.
  • the label is attached to the bottle 24, this is first placed on the flattened portion 29 of the stamp 2.
  • a discharge star (not shown) connected downstream of the rotary table 20, the strip 31 is then folded over by means of rollers or the like and pressed against the top of the bottle stopper.
  • a rotary device 3 is assigned to each punch 2, which is essentially formed by the control cam 4, the roller 5 and the spring element 10.
  • the function of this rotating device 3 is as follows:
  • the sleeve 9, including all parts attached or mounted thereon is first moved downward by a corresponding drop in the stroke curve 11, while maintaining the relative position shown in FIG. 2, until the stamp 2 with its friction coating 18 on the closure of the bottle 24 hits. This stops its height movement. The lowering movement of the sleeve 9 is continued even further, the spring element 10 being compressed. In this way, on the one hand, a sufficiently large clamping force is generated between the plate 1 and the punch 2 even with tolerances in the height of the bottles 24 and, on the other hand, the roller 5 is moved downwards completely out of the effective range of the control cam 4 until the one shown in FIG. 1 lower end position of the sleeve 9 with the holder 8 and the roller 5 is reached.
  • the stamp 2 initially remains in its zero position and the bottle 24 is firmly clamped between the plate 1 and the stamp 2. If the plate 1 now performs its various rotations and positions under the action of the groove curve 23 in the course of the labeling process, these are transferred exactly to the bottle 24 and from there onto the stamp 2 with the aid of the friction linings 18 and 19.
  • the strip 31 then exactly meets the flattened portion 29 of the breast label when it is applied Stamp 2, caused by a corresponding choice of its zero position.
  • the rotating device 3 for the stamp 2 is ineffective as long as the stamp 2 is fixed by a bottle 24 in the height position shown in FIG. 1.
  • the stamp 2 in question immediately drops under the action of the spring element 10 until the control curve 4 hits the roller 5, which is kept unchanged. As a result, the stamp 2 is immediately aligned in its zero position in the manner described above. If there is no bottle 24 for a turntable 1 from the outset, the stamp 2 remains fixed in its zero position during its entire circulation through the labeling area.
  • the sleeves 9 are gradually raised by an increase in the stroke curve 11 from the lower end position shown in FIG. 1 to the upper end position shown in FIG. 2.
  • the stamp 2 remains on the bottle 24 under the action of the spring element 10 until the roller 5 hits the lower edge of the control cam 4 and then the stamp 2 also takes part in the lifting movement.
  • the possibly required rotation of the punch 2 can begin if the roller 5 first hits one of the two inclined ramps 6. This ensures that the stamps 2 have definitely reached their zero position even when the labeling machine is performing well when they are placed on a bottle 24 again.
  • the groove curve 23 can also be designed such that in the normal case the punches 2 already assume their zero position when they are lifted off the bottles 24. In this case, the rotating device 3 is only effective when bottles 24 break.
  • An adjustment of the zero position of the stamp 2 is possible in a simple manner by adjusting the holder 8 with the help of the clamping screw 30. If the labeling machine is converted to processing a type of bottle which requires normal rotationally symmetrical stamps or centering bells, the holders 8 can possibly be removed.
