Definitions

  • the invention relates to a device for the mechanical removal of screw caps from bottles, such as caps from juice, mineral water or also beer bottles, with at least one unit rotating the lid in the opening direction and at least one lifting unit used to transport the bottles and held in a carrier plate. in which both a device for holding and removing the bottles and a device for rotating the lid in the opening direction are arranged.
  • a device of the type described above is known from DE-A 2 132 244.
  • gripper heads are fastened to holding plates which can be moved horizontally and vertically by means of a swivel drive and, when they are brought into a corresponding position by the holding plate, can be placed on the bottles in order to grip one bottle each with an associated gripping head.
  • a swivel drive can be moved horizontally and vertically by means of a swivel drive and, when they are brought into a corresponding position by the holding plate, can be placed on the bottles in order to grip one bottle each with an associated gripping head.
  • a screwdriver During the transport of a seized bottle, it is either uncapped or capped with a screwdriver.
  • a drive common to all gripping heads can have a disadvantageous effect on the operational safety of the known device, because e.g. Mechanical malfunctions in only one of the unscrewing and unscrewing devices result in all unscrewing and unscrewing devices failing. The entire device must then be taken out of operation for a longer period of time for the corresponding repair work.
  • each lifting unit is each provided with a separate rotary drive, that a drive pin of the drive extends vertically through a receiving bore in the carrier plate and continues via a coupling member as a drive shaft, the Drive shaft is mounted in a non-rotatably, but liftable and lowerable in the support plate seated piston shaft, inside which it runs coaxially, that the piston shaft is arranged coaxially inside a cylinder housing connected to the support plate, the piston shaft relative to the cylinder housing vertically downwards, can therefore be pressed against the bottle to be freed from the fact that the piston skirt is provided with a cone arranged at its lower end, which enters between at least two support rollers which are articulated on the cylinder housing and are connected in a fixed position with a lever s are, at the lower end via a further joint on the bottle engaging gripper jaws are pivotally arranged, and that between the lower end of the drive shaft and the cover to be removed, couplings are provided which are
  • the device according to the invention thus has the advantage that the cover can be unscrewed at the same time as the lifting process.
  • the individual parts of the unit can also be attacked on the bottle or on its lid at the same time.
  • the device according to the invention can preferably be applied to bottles which are temporarily stored in the above-mentioned collecting containers ("boxes").
  • the spacing and the number of lifting units of the type mentioned are used which correspond to the bottles arranged in the collecting container.
  • the use of such a device means that the removal and replacement of the bottles can be carried out very quickly.
  • one or more horizontally displaceable devices are used in particular for containers with numerous bottles, in which the number of aggregates is smaller than the number of bottles, so that the aggregates are only assigned to a part of the bottles .
  • the lids of four of these bottles which are therefore square to one another, could be removed one after the other by a device provided with correspondingly square lifting units.
  • devices that work simultaneously, each time but only remove a limited number of bottles. In the example above, two devices would be required, each with four lifting units, which simultaneously grasp the existing bottles and unscrew the lids there.
  • Such a division has the advantage that the device allows the existing bottles to be acted upon both in succession and simultaneously. In extreme cases, it may even be sufficient if a single movable unit is present, which captures the bottles one after the other and can be moved horizontally in a frame assigned to the carrier plate on rails arranged there, the movement being fixable in its initial and final position by a switch or the like is.
  • the individual units are each provided with a separate drive, which can be an electric motor.
  • a separate drive which can be an electric motor.
  • a pneumatic or hydraulic motor here.
  • intermediate gears are required in an electric motor, while a hydraulic motor is set in this way can be that it runs slowly.
  • the drive pin of the drive which runs centrally through the receiving bore of the support plate, e.g. of the electric motor, extends perpendicularly through the receiving bore, and continues beyond a coupling member as the drive shaft, the drive shaft in turn being mounted in the piston shaft, inside which it extends coaxially. Since the piston shaft in turn sits coaxially in the interior of a cylinder housing, the device can be provided with a pneumatic drive which presses the piston shaft downwards relative to the cylinder housing when it is triggered, that is, against the bottle to be freed from the lid.
  • a shaft section which is connected to the shaft of the drive motor or formed by the shaft itself is expediently provided coaxially within the piston shaft and rotates slowly within the piston shaft.
  • This driven shaft section is also carried by the piston when the piston moves downward, roller bearings being provided between the shaft and the piston shaft. It is therefore necessary for the shaft or its section to perform a relative movement with respect to the motor drive or its shaft, for example as a result can come about that, in a manner known per se, two sections of a coupling member are provided which interlock telescopically, the torque being transferable by means of teeth which enable longitudinal displacement.
  • couplings of various types can be provided between the shaft end and cover in the event that these two parts come into contact.
  • Such a coupling can - as described - consist, for example, that gripper-like jaws are connected to the shaft, which act on the cover under frictional force.
  • connection between the shaft end and the cover is achieved by the fact that at least one eccentrically arranged pointed pin is present at the shaft end, which penetrates the cover when the shaft moves downward and thus a fixed connection between the shaft pin and the shaft Lids. As soon as the pin has penetrated the cover, it is taken away by the shaft. Due to the low rotational speed, such a connection can be made while the shaft is running.
  • the arrangement described above has the essential advantage that construction material is saved.
  • the cover which may be adhering to a plurality of pins of this type, out of the device by means of an ejector
  • the ejector consisting of a pin which is located in the center of the shaft and is arranged there to be longitudinally displaceable is.
  • this ejector can be acted upon by a correspondingly small compressed air unit in the ejector direction, ie downwards; however, mechanical devices are also conceivable which are arranged in the interior of the piston skirt due to eccentrics or the like and which, in a specific position, strike the upper end of the ejector.
  • grippers can also be provided for the cover, which produce the frictional connection with the shaft.
  • the ejection may be simplified if an air flow is generated which is directed against the cover from above and separates it from the tips.
  • the gripper jaws can be provided with adhesion-increasing bristles or the like which face the neck of the bottle.
  • adhesion-increasing bristles or the like which face the neck of the bottle.
  • rubber coatings or coatings made of rubber-like plastic can also be provided.
  • the essential parts of the pneumatic system can be arranged in the upper part of the cylinder head, which in turn is connected to the carrier plate via a flange which can be held by three screws and which thus reliably holds the unit.
  • a connection makes it possible to detach the entire assembly including the shaft, ejector and gripper and to remove it from the traverse with minimal downtime for the purpose of replacement.
  • a device 1 is assigned to a collecting container 3 which holds eight bottles 2 arranged next to one another in rows of four, this collecting container 3 being commercially available and used for the simultaneous sale of several filled bottles 2.
  • the device 1 assigned to the collecting container 3 and shown in FIG. 1 exists according to the illustrated embodiment from a frame 4 which can accommodate a carrier plate 5, the carrier plate 5 serving to hold (in the exemplary embodiment shown: eight) lifting units 6, one of which is assigned to one of the bottles 2 in the collecting container 3.
  • the frame 4 and thus the support plate 5 are arranged displaceably on rails 7 and 8, the rails 7 and 8 being arranged at right angles to one another in the exemplary embodiment shown, but need not be.
  • the rails 7 and 8 can engage above and below the frame 4 or the carrier plate 5 and can be locked in their respective setting position.
  • the rails 7 and 8 make it possible, for example, when using relatively few units (for example four units in the exemplary embodiment shown) to achieve the number of bottles not achieved in each case by moving the carrier plate 5 with the frame 4 appropriately and quickly over the bottles not previously taken.
  • FIG. 1 shows the device 1 seen from below, the individual units 6 protruding downward from the carrier plate 5, ie in the direction of the bottles 2.
  • the outer cylinder housing 9 is visible in FIG. 1, from each of which a piston shaft 10 emerges from below.
  • This piston shaft 10 serves on the one hand to actuate a gripper 11 which holds the respective bottle 2 by means of articulated gripper jaws 12, the lid 13 of which is to be removed (cf. FIG. 2).
  • at least two levers 14 can be provided in the exemplary embodiment according to FIG. 2, each of which can be pivoted about a fixed articulation point 15 and at whose ends pointing towards the bottle 2 the articulated holders 17 of the gripper jaws 12 are articulated via joints 16.
  • the gripper jaws 12 are thus brought into contact with the bottle 2 in the neck region thereof when their upper ends 18 are pressed apart in the direction of the double arrow 19. This pushing apart, like all other operations, can be done pneumatically.
  • Fig. 3 shows a schematic representation of this actuation of the jaws 12, the spreading apart in the direction of the double arrow 19 being carried out by the piston shaft 10, at the end facing the jaws 12 a cone 20 is arranged, which acts on stationary support rollers 21 spread the levers 14 apart and thus bring the gripper jaws 12 against the bottle 2 in the opposite direction.
  • Fig. 4 shows the individual components in their single stage, i.e. at a time when the cone 20 has not yet acted on the support rollers 21 in the opening direction and thus on the gripper jaws 12 in the closing direction.
  • FIG. 4 also shows a centrally arranged ejector 30, which serves to eject the turned-off cover 13.
  • the ejector designed as a pin can be pressurized with compressed air.
  • Fig. 6 shows the overall device with its details in section. Thereafter, the piston shaft 10 is arranged vertically displaceably and pneumatically acted upon, in the interior of which a drive shaft 26 is rotatably mounted about its vertical axis via roller bearings 25, which unscrews the cover 13 serves.
  • the driver for this is a pin 127, which is inserted into the cover 13 outside of the center from above, so that the continued rotation of the shaft 26 leads to a drive of the cover 13 and thus to a rotation in the opening direction.
  • several carriers of this type can also be provided.
  • the ejector 30 coaxial within the shaft 26 is the ejector 30, which can be moved vertically downward in the direction of arrow 35 via its air connections 31 and 32 (cf. FIG. 4), so that the removed and twisted cover 13 is promoted downwards.
  • FIG. 5 is the section V / V in FIG. 6 and illustrates the coaxial engagement of the ejector 30, the drive shaft 26 of the piston shaft 10 and the cylinder housing 9.
  • the gripper jaws 12 can additionally be acted upon by springs 36 in the contact direction.
  • FIG. 7 shows the overall assembly in a side view and illustrates its mounting, in particular on the carrier plate 5.
