Definitions

  • the invention relates to a device for centering and aligning vessels according to the preamble of claim 1.
  • a generic device (DE-PS 33 08 489) which is suitable for centering and aligning vessels with depressions provided for this purpose in the base area.
  • the alignment rotation of the vessel required for aligning the vessel that is, the alignment rotation of the vessel required until a spring-loaded alignment cam engages in the recess on the bottle bottom, is rotated by means of a rotatably mounted centering ring, which is rotated for this purpose by means of a fixed friction surface while the one receiving the vessel bottom Stand plate is held against rotation.
  • a device for aligning cylindrical bottles is also known, in which these are lifted by driving through the alignment section by means of a height-controllable centering cone and set in rotation until an alignment cam engages. This is done either by means of a friction surface acting directly on the bottles or by means of a friction wheel connected to the centering cone.
  • problems arise during operation due to the sometimes not inconsiderable dimensional tolerances of the bottles and their frequently wet surface (condensed water, etc.), so that reliable alignment cannot be guaranteed in all cases.
  • the friction surface used depends on the bottle format, ie it has to be replaced when changing the vessel and also exerts undesirable lateral forces on the centered bottle.
  • the possible uses of the device are limited to bottles with a bottom cone.
  • the main disadvantage is the extremely complex construction due to the required height control of the centering cone, which is due to the space required for this in a rotary table of a modern high-performance labeling machine can hardly be accommodated. This is especially true for the version in which the centering cone is set in rotation by an additional friction wheel.
  • the invention is therefore based on the object to improve a generic centering and aligning device with the simplest means to the effect that it can also be used for an equipment machine with a conveyor which can be operated via a simple turntable control of conventional type, e.g. by means of roller lever and groove curve.
  • the annular outer body of the plate is non-rotatably connected to its associated control device in the transporter and has at least one recess on the side, it is possible despite the use of a roller lever groove curve control in the transporter that is common in standard labeling machines to achieve the required alignment rotation of the container through the im To make the interior of the housing freely rotatably supported without additional complicated gear mechanisms having to be accommodated in the transporter, which would make changes to the control device and the housing of the transporter unavoidable.
  • the aligning rotary movement of the inner body can be generated by a friction element, which is assigned to the housing of the plate in height in the region of the aligning path parallel to the path of the transporter and which extends through the lateral recess of the housing and rests on a friction body which is connected to the inner body in a rotationally fixed manner.
  • the housing of the plate with its lateral recess points towards the friction element and is held stationary by the control device relative to the feed dog while passing through the alignment section.
  • the plates carrying the vessels are arranged on a conveyor designed as a rotary table, it being particularly expedient to arrange the friction element on the radially outer side of the orbit of the plates.
  • the use of a friction element, which is formed by a flexible belt, is particularly favorable.
  • a flexible belt not only allows it to be fixed to the transporter housing, but also enables the use of an endless belt, which can be mounted so that it can be driven around two pulleys, for example. This makes it possible to drive the belt drum assigned to the plate either in or against the direction of transport of the plate.
  • the latter option is therefore particularly inexpensive, since it enables the maximum possible number the alignment rotations of the inner body can be increased while driving through a lengthwise predetermined alignment path, which makes it possible without further extension of the alignment path to rotate the vessel several times completely, so that this occurs, for example, if the alignment element does not engage during the first revolution can still take place with a second or third rotation, which means a considerable increase in alignment security.
  • the design of the annular outer body and the inner body is influenced by the type of vessel centering. Basically, the centering takes place either on the outer contour of the vessel in the bottom area or with the help of a conical surface in the bottom of the vessel, if there is one.
  • the inner body is designed as a base plate and the annular outer body as a centering ring with a centering surface.
  • Both the shape of the base plate and that of the friction body connected to it, which cooperates with the friction element, depends on whether a vessel has to be aligned on the bottom or the side wall, ie whether an alignment element acting on the bottom of the vessel or the side wall is used .
  • the respective alignment element is connected to the centering ring which, according to an advantageous development of the invention, is quickly detachably connected to the housing of the plate.
  • this constructive design permits either a centering ring with a radially displaceable top surface of the plate to the axis of rotation of the plate or an alignment element mounted pivotably about an axis parallel to this, or a Centering ring with an axially in the area of the centering surface on its underside, parallel to the turntable axis, displaceable or pivotable about an horizontally lying axis.
  • the alignment element used in each case is spring-loaded in such a way that it is constantly pressed against the vessel bottom or side wall during the alignment process until it engages.
  • a base plate can advantageously be used, on the outer circumference of which a cylindrical outer surface is formed which forms the friction body and which is perpendicular to the interior of the plate housing.
  • the outer diameter of the base plate can easily be chosen larger than the inner diameter of the centering surface of the centering ring.
  • the stand plate which is supported in a vertically resilient manner in the housing of the plate, rests with its upper side on the underside of the centering ring in the unloaded state, as a result of which the upper stop position is defined which the stand plate assumes during the pushing on or removal of the containers onto or from the transporter, the base of the base plate is substantially flush with the surface of the centering ring.
  • a base plate can be used, the outer diameter of which is dimensioned smaller than the inner diameter of the centering surface and in such a way that the width of the resulting annular gap allows a non-contact grasping of the underside of the centering ring stored alignment element allowed up to the bottom of the vessel.
  • the base plate is equipped with a friction body, which consists of a disk, which is rotatably connected to it below it at a distance from the base plate, and a ring fastened or molded on its circumference, the inside diameter of the ring being larger than the outside diameter of the base plate and the inside diameter of the Centering surface is dimensioned, in such a way that the ring of the friction body engages around the alignment element attached to the underside of the centering ring to the outside.
  • the side of the friction body designed as a ring facing the centering ring can determine the upper stop position of the base plate together with the latter.
  • the height control device of the centering bell over the axially clamped vessel before or while driving through the alignment section, to move the stand plate a little from the upper stop position into an intermediate position between the upper and lower stop positions lower and lower into the lower stop position only after passing the alignment section, but before reaching the equipment station.
  • the lower stop position of the base plate is defined by a stop surface formed on the inside of the housing, so that the base plate is frictionally connected to the control device of the plate in the lower stop position, and thus also in the further course of the furnishing process about the Stand plate part of the torque required to carry out the specified turning program is transferred to the bottom of the vessel.
  • This has the advantage that the torque must not only be transmitted exclusively through the centering surface and the alignment element connected to the centering ring. In the intermediate position, however, the base plate can rotate freely to align the vessel.
  • the stand plate can be brought into its lower stop position by the height control of the centering bell before or while driving through the alignment section, without the rotation of the stand plate being impeded for the purpose of alignment.
  • the centering ring is quickly connected to the housing of the plate.
  • a bayonet lock is advantageous.
  • the centering ring can be equipped with a bore which interacts, for example, with a resilient dowel in the housing of the plate. If the centering ring is to be removed, it is sufficient to press the dowel pin into the housing by means of a pin, to twist the centering ring by a few degrees until the bayonet lock releases it in terms of height. Then the Centering ring - if necessary also the base plate - be removed and replaced by other specimens.
  • a further development also provides for a recess on the circumferential surface of the centering ring, which, when passing through an equipment station, is aligned with a locking element connected to and rotating with the transporter.
  • Each locking element is assigned to a plate and is radially controllable with respect to the centering ring, so that it can be brought into engagement with the recess of the centering ring by means of a fixed control cam arranged in the area of the equipment station, with the result that while in the equipment station the in the control device of the plate existing turning play is switched off. This measure ensures an extremely precise label fit in relation to the circumferential position on the vessel.
  • the centering ring In order to achieve a constant adhesive height, for example of a label, with respect to the bottle bottom regardless of the shape tolerances of the containers, it is particularly advantageous to design the centering ring to be displaceable in height with respect to the transporter, the centering ring assuming a defined upper end position in the unloaded state, which can also determine the upper stop position of the base plate.
  • the height of the centering ring can be achieved constructively in several ways, for example, that the housing carrying the centering ring is guided so that it can be moved vertically on the conveyor, or only the centering ring is fixed in height relative to the housing or part of the housing and another part together with the Centering ring is slidably guided on it.
  • a particularly simple and a large lateral recess design of the housing can be formed by using a support plate rotatably and vertically connected to the control shaft rotatably mounted in the housing of the transporter, with at least three telescopic rods fastened thereon in the area of its outer edge, each of which consists of one Bolts with a sleeve guided thereon and an integrated compression spring can exist, wherein a stop surface determining the upper end position can be formed between the sleeve and the bolt.
  • the centering ring can rest on an annular disc which is connected to the ends of the telescopic rods facing away from the support plate.
  • a more stable design of the housing has an annular body which is arranged on the support plate in a manner that is fixed against rotation and has at least one recess on its outer surface.
  • the ring body is axially displaceable relative to the support plate and is held in an unloaded state in an upper end position by compression springs.
  • the ring body has bores with integrated compression springs, into which bolts arranged on the support plate engage.
  • the centering ring lies directly on the ring body.
  • the base plate arranged in the interior of the housing is equipped with an axle journal, which is axially displaceably and rotatably mounted in a blind hole open to the top of the transporter of the control shaft rotatably mounted in the housing of the rotating transporter.
  • the axle journal which is connected to the base plate in a rotationally fixed manner, is supported by a compression spring on an axial bearing arranged at the bottom of the blind hole.
  • the device can also be used as a pure centering plate for shaped containers which do not have a rotationally symmetrical cross section and do not need to be aligned.
  • the ring body of the housing is provided on its radially inner side facing the base plate with a vertical groove in which, for example, the head of a hexagon screw, which in turn is attached to the circumference of a corresponding base plate, is axially displaceable.
  • the base plate required for this has no friction body, since no alignment is necessary.
  • the centering ring having the centering surface corresponding to the cross section of the vessel has no alignment element.
  • the device can be used as desired for aligning the bottom and side walls of vessels, as well as for centering shaped containers, the device being able to be easily installed on any conveyor of a standard labeling machine.
  • the device can be designed so that for centering and aligning vessels no lifting of a centering cone and thus no separate height control device is necessary.
  • the ring-shaped outer body of the plate receiving the bottom of the plate is designed as a standing ring which is vertically movable, ie axially displaceable in the direction of the axis of rotation of the plate, the standing ring being spring-loaded in an unloaded state, an upper one Assumes the stop position in which the standing surface projects above or at least is flush with the top of the inner body designed as a truncated cone and the alignment element.
  • the vessel bottom and thus the spring-loaded base ring can be lowered in an extremely simple manner immediately after the vessel is pushed until the conical depression in the vessel bottom reaches the level arranged, frustoconical centering element meets. From this moment the lowering movement of the vessel is stopped.
  • the height control device of the centering bell is usually equipped with a compensation spring to compensate for vessel height tolerances.
  • the likewise spring-loaded alignment element hits the bottom of the vessel and is lowered by it in the same way as the base ring, a compression spring permanently pressing the alignment element against the bottom of the vessel.
  • the soft compression springs acting on the base ring are dimensioned so that the friction between the base ring and the part of the vessel bottom surface in contact with it turns out to be significantly lower than the friction between the conically recessed area of the vessel bottom and the centering cone, so that the vessel can be rotated by the driven truncated cone-shaped centering element while driving through the alignment section despite the stationary standing ring, with slippage occurring between the bottom of the vessel and the standing ring until the spring-loaded aligning element can engage in the corresponding recess on the bottom of the vessel and further rotation of the vessel during prevents the alignment phase.
  • slip For the rest of the alignment section, slip now occurs either on the frustoconical centering element or between the friction body, which is connected to it in a torsion-proof manner and is arranged in the cavity of the housing of the plate, and the friction element which bears against it and extends through a recess in the housing.
  • the torque transfer from the plate control to the vessel takes place for the execution of the turning program, on the one hand through the aligning element which engages positively on the bottom of the vessel and, on the other hand, through the friction between the bottom of the vessel and the base ring, which is non-rotatable with the housing of the plate is connected.
  • the centering bell pressing the vessel against the plate is raised by its associated control device for this purpose, so that the springs acting on the underside of the standing ring are able to move it into its upper stop position , whereby the vessel is lifted from the centering cone and the alignment element and can be easily removed from the plate.
  • FIG. 1 schematically indicates the orbit of the conveyor 1 designed as a turntable, onto which the vessels arriving from the feed conveyor 50 are pushed by means of an inlet star 51.
  • the alignment section 18 begins, the length of which is determined by the arc section of the friction element 13 arranged on the radially outer side of the conveyor 1 on the orbit of the plate 2, which is designed as a flexible circumferential belt.
  • the associated one is assigned Centering bell 15 lowered by its height control 14 (Fig. 2), so that the vessel 3 is clamped axially between the head and bottom surface.
  • the alignment path 18 As the alignment path 18 is traveled through, the alignment of the vessels 3 takes place, which in the further course reach an equipment station 52. At this point, for example, a label is applied to the vessel in a known manner and brushed onto the vessel contour in the further circulation area of the transporter 1. Then, shortly before reaching the outlet star 53, the centering bell 15 is lifted from the vessel head by its height control 14, so that the vessel 3 can be transferred from the conveyor 1 to the conveyor 54.
  • each plate 2 can be assigned a controllable locking element 26 which rotates with the transporter 1 and which is displaced radially in the direction of the plate 2 in the area of the equipment station 52 by means of a fixed control cam 27 and engages with one can be brought not shown recess on the circumference of the centering ring.
