Definitions

  • the invention relates to a glue scraper which can be adjusted to a glue roller in a labeling machine and which is pivotably mounted on a shaft with a carrier, the carrier being spring-loaded in the direction of a stop fixed to a minimum gap width of the glue scraper with respect to the glue roller and being parallel a further adjustable, frame-fixed stop is provided for this stop, on which the support can be supported by means of an actuator with a constant travel.
  • Labeling machines for bottles known from practice have a glue scraper of the type mentioned in the introduction in order to be able to adjust the thickness of the glue layer on the glue roller depending on the type of labels used for the labeling.
  • the setting of the glue scraper in an almost pressure-free system on the glue roller serves to make the glue roller glue-free when the labeling machine is idling, when no more glue is removed from the glue roller for the labels.
  • the invention has for its object to take precautions with a glue scraper of the type mentioned, which allow a change of the glue scraper during operation.
  • the actuator is designed as a multi-stage actuator.
  • the actuating device can either be a cylinder-piston unit with actuating cylinders connected in series, preferably from the actuating cylinders an actuating cylinder with its piston rod acts on the piston of another actuating cylinder, which has the greater stroke compared to the first actuating cylinder, or a cylinder-piston unit with actuating cylinders arranged in parallel with one another include different sizes strokes or a combination of these cylinder piston units.
  • the two-stage setting device it is possible to adjust the glue scraper parts to different operating positions during operation in order to take into account the performance-dependent flattening of the elastic glue roller. In this way, the glue scrapers are brought into a first position with low output. If the machine is then started up to high power, the adjusting device moves the glue scraper further towards the glue roller, so that the glue gap at high power is essentially equal to the glue gap at low power.
  • the actuating device has two cylinder piston units connected in parallel, each with series-connected actuating cylinders with different stroke lengths, this actuating device offers five different setting options, namely the position of the glue scraper in an almost pressure-free system on the glue roller and four positions for different gap widths.
  • the driving device can be constructed in a simple manner with a driver held on a carrier and an abutment held by the other carrier.
  • the solution according to the invention can be implemented both with an idle stroke and without an idle stroke. Without an idle stroke, the control of an actuator leads to the same gap width settings of the scraper parts on the glue roller, with an idle stroke to different gap widths. In any case, however, the driving device does not hinder the independent actuation of the two actuators in order to set different gap widths.
  • the flexibility of the glue scraper for setting to different gap widths can be further improved in that the driving device has an adjustable idle stroke.
  • the two carriers are coupled to one another by means of a double-acting entrainment device with such an idle stroke that the entrainment device does not respond in the actuating range of the actuators.
  • a double-acting driving device can, however, also be provided as an alternative to the single-acting driving device.
  • Such a driving device allows both scraper parts to be adjusted either with one or the other actuator, which is only possible with one of the two actuators in the case of a driver acting on one side.
  • each stop set to the minimum gap width of the associated glue scraper part can be achieved according to one embodiment of the invention by a pressure piece acting on a wedge surface.
  • a support 3 carrying a one-piece glue scraper 2 is pivotably mounted on a shaft 1.
  • the carrier 3 carries 4.5 actuators 6.7 on lever arms in the form of independently actuated pressure actuating cylinders which are supported in the extended state on adjustable stops 8.9.
  • These stops 8, 9, which can be adjusted by means of rotary knobs 8a, 9a, are carried by a holder 10, which is adjusted beneath the glue scraper 2 on the shaft 1 by a screw 11.
  • adjusting screws 13.14 form stops for bolts 15.16 arranged next to the actuators 6.7 on the lever arms 4.5, so that with them in unactuated actuating cylinders 8.9 for idling operation the pivoting of the carrier 4, 5 can be preset to the smallest gap width, the glue scraper 2 resting against the glue roller 19 practically without pressure.
  • the force generated in this way has a stabilizing effect on the unsteady force development caused by the inhomogeneous glue between the glue scraper 2 and a glue roller 19.
  • the two actuators 6, 7 designed as hydraulic actuating cylinders are designed for different strokes, so that when one actuator 6 is acted upon, the glue scraper 2 is adjusted to a first gap width and by acting on the second actuator 7, the glue scraper 2 is adjusted to a second different gap width.
  • the same result can also be achieved with the same strokes by setting the stops 8, 9 differently.
  • two actuators 26, 27 arranged one behind the other can also be provided in accordance with FIGS. 4a to 4c.
  • the two actuators 26, 27 designed as actuating cylinders like the actuators 6.7 of the first exemplary embodiment, can be pressurized independently of one another.
  • Each actuating cylinder 26, 27 has a piston 26 ", 27" supported on a spring 26 ', 27'.
  • the piston rod 27 "'of the actuating cylinder 27 acts on the piston 26" of the actuating cylinder 26, while the piston rod 26 "' forms the stop 28 of the actuator.
  • the two actuating cylinders 26, 27 are designed such that the actuating cylinder 27 has a greater stroke than the actuating cylinder 26 has.
  • actuating cylinders 26, 27 connected in series can, however, also replace each of the actuating cylinders 6, 3 of exemplary embodiment 3, in which case the actuating cylinders 26 on the one hand and the actuating cylinders 27 on the other hand have different strokes.
  • Such training serves to multiply the possibilities for placement.
  • a lever 29 is fastened to the carrier 3. So that when the He bels 29 the glue scraper 2 is not pivoted too far, the bracket 10 fixed to the frame carries a stop pin 30.
  • the embodiment of Figures 5 to 7 differs from the described embodiment essentially in that the glue scraper consists of two superposed parts, each with its own carrier 3a, 3b, and the two carriers 3a, 3b via a single-acting and / or bilateral driving device 21 to 22a, 24, 25 are coupled. It is therefore sufficient for an understanding of the exemplary embodiment with the divided glue scraper if the further description is restricted to these differences.
  • a lever 21 attached to the carrier 3a forms a one-sided driver, at the end of which there is an adjustable abutment 21a. Adjacent to it, attached to a lever arm 22 of the carrier 3b, is an adjusting screw 22a.
  • the driver designed as a lever 21 and the lever arm form a driver device which is effective on one side between the glue scraper parts.
  • the function of the one-sided driving device 21 to 22a is as follows: If the actuator 6 is pressurized when the actuator 7 is depressurized, it pivots the support 3a and thus also the lever 21 acting as a driver 21, supported by the adjustable stop 8. As soon as the lever 21 strikes the adjusting screw 22a with the abutment 21a, the support 3b is also pivoted via the lever arm 22. The gap width of the glue scraper parts on the glue roller 20 depends on the set idle stroke. The carrier 3b can then be pivoted further by pressurizing the actuator 7. In the two possible extreme cases, the carrier 3b is carried simultaneously in one case and not at all in the other case. In the latter case, the pivoting movements of the two glue scraper parts are completely independent of one another.
  • FIG. 5 also shows a driver device acting on both sides. It consists of a pin 24, which is firmly inserted in the carrier 3a, and a bore 25 in the carrier 3b, in which the pin 24 engages with play.
  • the size of the bore 25 is dimensioned so that a limited independent adjustment of the scraper parts is possible.
  • the function corresponds to the one-sided entrainment device, but in this case the common movement can be carried out either by the actuator 7 or by the actuator 6.
  • the driving device 24, 25 acting on both sides can be provided in addition to the driving device 21 to 22a. In this case, it serves to carry the lower carrier 3a with the lower scraper part when both scraper parts are to be pivoted away from the glue roller 20 and subsequently pivoted back again by means of the lever 2a attached to the carrier 3b of the upper scraper part.
  • a pin 29 prevents pivoting too far.
  • the actuators 6, 7 are each designed as two-stage adjusting devices arranged in parallel or one behind the other, as shown in FIGS. 4a to 4c.
